1 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3 * lisp.mk: Adjust comments to the fact that term/internal is now
6 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
7 (msdos_fatal_signal): New function.
8 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
11 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
12 for GCC versions before 4.
13 (emacs_raise): Define to call msdos_fatal_signal.
15 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
16 iterator when starting in the middle of a display or overlay
19 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
21 Fix data-loss with --batch (Bug#9574).
22 * emacs.c: Include <close-stream.h>.
23 (close_output_streams): New function.
24 (main): Pass it to atexit, so that Emacs closes stdout and stderr
25 and handles errors appropriately.
26 (Fkill_emacs): Don't worry about flushing, as close_output_stream
29 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
30 The symptom is a diagnostic "GLib-WARNING **: In call to
31 g_spawn_sync(), exit status of a child process was requested but
32 SIGCHLD action was set to SIG_IGN and ECHILD was received by
33 waitpid(), so exit status can't be returned." The diagnostic
34 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
35 The real bug is a race condition between Emacs and glib: Emacs
36 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
37 so that glib can't find it. Work around the bug by invoking
38 waitpid only on subprocesses that Emacs itself creates.
39 * process.c (create_process, record_child_status_change):
40 Don't use special value -1 in pid field, as the caller now must
41 know the pid rather than having the callee infer it. The
42 inference was sometimes incorrect anyway, due to another race.
43 (create_process): Set new 'alive' member if child is created.
44 (process_status_retrieved): New function.
45 (record_child_status_change): Use it.
46 Accept negative 1st argument, which means to wait for the
47 processes that Emacs already knows about. Move special-case code
48 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
49 processes that have already been waited for, by testing and
50 clearing new 'alive' member.
51 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
52 now does this internally.
53 (handle_child_signal): Let record_child_status_change do all
54 the work, since we do not want to reap all exited child processes,
55 only the child processes that Emacs itself created.
56 * process.h (Lisp_Process): New boolean member 'alive'.
58 Omit duplicate definitions no longer needed with gcc -g3.
59 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
60 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
61 Define only as macros. There's no longer any need to also define
62 these symbols as enums or as constants, since we now assume
63 gcc -g3 when debugging.
65 2012-11-03 Chong Yidong <cyd@gnu.org>
67 * process.c (wait_reading_process_output): Clean up the last
70 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
72 * process.c (wait_reading_process_output): Avoid a race condition
73 with SIGIO delivery (Bug#11536).
75 2012-11-03 Chong Yidong <cyd@gnu.org>
77 * buffer.c (cursor_type): Untabify docstring.
79 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
81 * frame.h (struct frame): Drop can_have_scroll_bars member
82 which is meaningless for a long time. Adjust comments.
83 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
84 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
86 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
88 * window.c (decode_next_window_args): Update window arg after
89 calling decode_live_window and so fix crash reported at
90 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
91 by Juanma Barranquero <lekktu@gmail.com>.
92 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.

102 2012-11-02 Eli Zaretskii <eliz@gnu.org>
104 Implement backtrace output for fatal errors on MS-Windows.
105 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
106 (BACKTRACE_LIMIT_MAX): New macro.
107 (w32_backtrace): New function.
108 (emacs_abort): Use w32_backtrace when the user chooses not to
109 attach a debugger. Update the text of the abort dialog.
111 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
113 Window-related stuff cleanup here and there.
114 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
115 Use decode_any_window.
116 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
117 * xdisp.c (Fformat_mode_line): Likewise.
118 * font.c (Ffont_at): Use decode_live_window.
119 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
120 * window.c (decode_next_window_args): Likewise.
121 (decode_any_window): Remove static.
122 * window.h (decode_any_window): Add prototype.
123 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
124 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
127 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
129 Remove pad from struct input_event.
130 * termhooks.h (struct input_event): Remove padding field.
132 * keyboard.c (event_to_kboard): Simplify because frame_or_window
133 member is never cons for a long time. Adjust comment.
134 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
135 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
136 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
137 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
139 2012-11-01 Eli Zaretskii <eliz@gnu.org>
141 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
143 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
145 Fix crash when using Emacs as commit editor for git (Bug#12697).
146 * callproc.c (setpgrp): Remove macro, as we now use setpgid
147 and it is configured in conf_post.h.
148 (Fcall_process): Don't invoke both setsid and setpgid; the former
149 is enough, if it exists.
150 * callproc.c (Fcall_process, child_setup):
151 * process.c (create_process): Use setpgid.
152 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
154 * dispnew.c (init_display): Initialize the foreground group
155 if we are running a tty display.
156 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
157 * lisp.h (init_foreground_group): New decl.
158 * sysdep.c (inherited_pgroup): New static var.
159 (init_foreground_group, tcsetpgrp_without_stopping)
160 (narrow_foreground_group, widen_foreground_group): New functions.
161 (init_sys_modes): Narrow foreground group.
162 (reset_sys_modes): Widen foreground group.
164 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
166 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
168 2012-10-31 Martin Rudalics <rudalics@gmx.at>
170 * minibuf.c (read_minibuf): Restore current buffer since
171 choose_minibuf_frame calling Fset_frame_selected_window may
172 change it (Bug#12766).
174 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
176 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
178 2012-10-30 Kenichi Handa <handa@gnu.org>
180 * font.c (Ffont_at): If WINDOW is specified and it is not
181 displaying the current buffer, signal an error.
183 2012-10-29 Daniel Colascione <dancol@dancol.org>
185 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode): In
186 preparation for fixing bug#12739, move these functions from
189 * coding.h, coding.c: ... to here, and compile them only when
190 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
191 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
193 2012-10-28 Eli Zaretskii <eliz@gnu.org>
195 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
196 (timer_loop, getitimer, setitimer): Use it instead of
197 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
199 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
202 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
204 * nsterm.m (NO_APPDEFINED_DATA): New define.
205 (last_appdefined_event_data): New variable
206 (last_appdefined_event): Remove.
207 (ns_select): Initialize t from last_appdefined_event_data instead
208 of [last_appdefined_event data1].
209 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
210 remove last_appdefined_event (Bug#12698).
212 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
214 * frame.c (x_set_font): Catch internal error.
216 2012-10-27 Eli Zaretskii <eliz@gnu.org>
218 Avoid overflow in w32 implementation of interval timers.
219 When possible, for ITIMER_PROF count only times the main thread
221 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
222 'volatile ULONGLONG' types. All the other data which was
223 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
224 (GetThreadTimes_Proc): New typedef.
225 (w32_get_timer_time): New function, returns a suitable time value
227 (timer_loop): Enter critical section when accessing ULONGLONG
228 values of the itimer_data struct, as these accesses are no longer
229 atomic. Call 'w32_get_timer_time' instead of 'clock'.
230 Remove unused variable.
231 (init_timers): Initialize s_pfn_Get_Thread_Times.
232 (start_timer_thread): Don't assign itimer->caller_thread here.
233 (getitimer): Assign itimer->caller_thread here.
234 (setitimer): Always call getitimer to get the value of ticks_now.

237 2012-10-26 Eli Zaretskii <eliz@gnu.org>
239 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
240 mouse movement events if the menu bar is active. This avoids
241 producing a busy "hour-glass" cursor by Windows if the mouse
242 pointer is positioned over a tooltip shown for some menu item.
244 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
246 Don't assume process IDs fit in int.
247 * emacs.c (shut_down_emacs) [!DOS_NT]:
248 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
249 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
250 Use pid_t, not int, to store process IDs, as 'int'
251 is not wide enough on a few platforms (e.g., AIX and IRIX).
253 2012-10-23 Kenichi Handa <handa@gnu.org>
255 The following change is to make face-font-rescale-alist work
256 correctly for non-ASCII fonts.
258 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
259 (font_open_for_lface): Handle Vface_font_rescale_alist.
261 2012-10-23 Chong Yidong <cyd@gnu.org>
263 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
265 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
267 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
269 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).

274 2012-10-21 Glenn Morris <rgm@gnu.org>
276 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
278 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
281 * frame.c (Fmouse_position, Fmouse_pixel_position):
282 * xdisp.c (produce_stretch_glyph):
283 Declare local vars only when they're needed.
284 This is clearer and avoids a warning on OpenBSD about unused vars.
285 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
286 This is safer, and avoids OpenBSD warnings about unused vars.
287 * keyboard.c (record_menu_key): Remove unnecessary decl.
288 (poll_timer): Define only if POLL_FOR_INPUT is defined.
289 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
290 as our definition clashes with OpenBSD's.
291 * xfaces.c (load_face_colors, check_lface_attrs)
292 (get_lface_attributes_no_remap, get_lface_attributes)
293 (lface_fully_specified_p, x_supports_face_attributes_p)
294 (tty_supports_face_attributes_p, face_fontset, realize_face)
295 (realize_x_face, realize_tty_face):
296 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
297 merely Lisp_Object *. This is more informative and avoids
298 a warning on OpenBSD about accessing beyond an object's size.
300 2012-10-20 Chong Yidong <cyd@gnu.org>
302 * lread.c (Fload): Doc fix (Bug#12592).
304 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
306 * font.c (Ffont_at): Fix previous change.
308 2012-10-19 Eli Zaretskii <eliz@gnu.org>
310 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
311 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html
314 * alloc.c (NSTATICS): Decrease to 0x800.
316 2012-10-19 Stefan Monnier <monnier@iro.umontreal.ca>

324 FD_ISSET (Bug#12668).
326 2012-10-18 Daniel Colascione <dancol@dancol.org>
328 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
329 (staticpro): If we run out of staticpro slots, die with an
330 informative error instead of just calling emacs_abort.
332 2012-10-18 Martin Rudalics <rudalics@gmx.at>
334 Fix two flaws reported by Dmitry Antipov.
335 * window.c (Ftemp_output_buffer_show): Remove.

377 Lisp_Object values. (Bug#12661)
379 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
380 to Lisp_Object. (Bug#12661)
382 2012-10-17 Kenichi Handa <handa@gnu.org>
384 * xdisp.c (reseat_1): Make the information stored in it->cmp_it

421 Set windows_or_buffers_changed.
423 2012-10-15 Daniel Colascione <dancol@dancol.org>
425 * dbusbind.c: Fix cygw32 build break when compiling with dbus
426 enabled by undefining the symbol "interface", which the platform
427 headers define to something incompatible.

456 removed or renamed by some other process immediately after Emacs
457 writes it but before Emacs stats it. Do not assume that stat (or
459 * image.c (slurp_file): Resolve the file name with fopen + fstat
460 rather than stat + fopen.
461 (pbm_read_file) [0]: Remove unused code with stat race.
462 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:
463 Remove ineffective code with stat race.
465 2012-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
467 * doc.c (get_doc_string): Don't signal an error if the file is missing.
469 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
471 * nsterm.m (hold_event_q): New static variable.

488 * fileio.c (check_existing): New function.
489 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
490 instead of calling 'stat', when what's needed is to check whether
491 a file exists. This avoids expensive system calls on MS-Windows.
494 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
496 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to

584 Use bool for boolean.
585 * keyboard.c (timers_run, swallow_events)
586 (detect_input_pending_run_timers):
587 * process.c (wait_reading_process_output):
588 Use unsigned for counter where wraparound-on-overflow is desired,
589 since unsigned is guaranteed to have that behavior and signed is not.
590 (read_char): Use ptrdiff_t for string length.
591 (get_input_pending): Remove first argument, since it was always
592 the same pointer-to-int (now pointer-to-boolean) &input_pending,
593 and behave as if it had that value. Return new value of
594 input_pending. All callers changed.
595 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
596 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

612 initializer for PVEC_NORMAL_VECTOR.
614 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
616 Clean out old termopts cruft.
617 * termopts.h (flow_control, meta_key): Remove unused decls.
618 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
619 Don't include termopts.h.
621 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
623 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
625 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
627 * commands.h (immediate_quit): Remove duplicate decl.
629 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>

636 2012-10-09 Eli Zaretskii <eliz@gnu.org>
638 * w32fns.c (w32_last_error): Change the return value to DWORD, to
639 match what GetLastError returns. Explain why the function is
642 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
643 'is_tooltip_frame', to avoid confusion with its global namesake.
645 2012-10-08 Daniel Colascione <dancol@dancol.org>
647 * xdisp.c (start_hourglass): Call w32_note_current_window when
648 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
649 build that caused Emacs to display the hourglass cursor forever.
651 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
652 which is broken under remote desktop, calculate the number of
653 colors available for a display based on the display's number of
654 planes and number of bits per pixel per plane. (bug#10397).
656 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
658 * nsfont.m (Vfonts_in_cache): New variable.
659 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
660 are used. Add cached fonts to Vfonts_in_cache.
661 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
663 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
665 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
667 (FONT_H): Define after FRAME_H.
668 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
671 * w32term.c: Remove leftover declaration of keyboard_codepage.
673 2012-10-08 Eli Zaretskii <eliz@gnu.org>
675 * makefile.w32-in (FONT_H): Add $(FRAME_H).
676 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
677 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
678 (GLOBAL_SOURCES): Add cygw32.c.
679 ($(BLD)/unexw32.$(O)):
681 ($(BLD)/w32console.$(O)):

683 ($(BLD)/w32heap.$(O)):
684 ($(BLD)/w32menu.$(O)):
685 ($(BLD)/w32proc.$(O)): Add w32common.h.
687 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
689 (x_to_w32_color): Don't modify the argument, modify a copy instead.
691 2012-10-08 Daniel Colascione <dancol@dancol.org>
693 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
694 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
695 accidental message numbering hole. Change other messages to
698 * w32select.h (HAVE_W32SELECT): Remove.
700 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
701 w32common.h instead of w32heap.h.
703 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)

706 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
707 (OS_NT, os_subtype, cache_system_info): Move declarations to

711 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
712 (w32_minor_version, w32_build_number, w32_subtype):
713 Remove duplicate definitions.
715 * w32fns.c: Include w32common.h; include w32heap.h only in
718 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
719 Use `report_file_error' instead of `error' in order to better
720 inform users of what went wrong. Increase NTGUI_UNICODE file
721 dialog box file name length to 32k, the maximum allowed by the NT
724 * w32common.h: New file.
725 (ROUND_UP, ROUND_DOWN, get_page_size)
726 (get_allocation_unit, get_processor_type, get_w32_major_version)
727 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
728 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
729 (OS_NT, os_subtype, cache_system_info): Move here.
731 * unexw32.c, unexcw.c: Include w32common.h.
733 * emacs.c (main): Use (defined (WINDOWSNT) || defined
734 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
735 to call syms_of_w32select.
737 * cygw32.h: Remove obsolete EXFUN declarations.
739 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
741 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
742 of w32inevt.o from SOME_MACHINE_OBJECTS.
744 2012-10-08 Daniel Colascione <dancol@dancol.org>
746 * image.c: Permanent fix for JPEG compilation issue --- limit
747 jpeglib `boolean' redefinition to Cygwin builds.
749 2012-10-08 Eli Zaretskii <eliz@gnu.org>
751 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
753 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
756 2012-10-08 Daniel Colascione <dancol@dancol.org>
758 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
759 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
760 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
761 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
762 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
763 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
764 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
765 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
766 now a supported configuration.
768 * Makefile.in: consolidate image variables into LIBIMAGE; add
769 W32_OBJ and W32_LIBS. Compile new files.
772 (_DebPrint) declare tracing facility for W32 debugging. We need
773 to unify tracing later.
775 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
776 unconditional use of W32 Unicode functions. Cygwin runs only on
777 100% Unicode operating systems.
779 * cygw32.c: New file. Define Cygwin-specific facilities.
780 (Fcygwin_convert_path_to_windows)
781 (Fcygwin_convert_path_from_windows): New user functions for
782 accessing Cygwin path-munging routines.
784 * cygw32.h: New file.
785 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
786 UTF-16LE strings temporarily inside non-Lisp-visible string
789 (w32_strerror): Just what it says on the tin.
791 * emacs.c: Make the NS fork-then-exec code for daemon-launching
792 also run for Cygwin; both systems have the same problem with using
793 GUI facilities in a forked child. Also call syms_of_cygw32,
794 syms_of_w32select in correct places.
796 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
797 needs fork-then-exec for daemon launching.
799 * font.h: Include frame.h.
801 * image.c: Use the image library cache machinery only when we're
802 compiling for native WINDOWSNT; Cygwin can use shared libraries
803 like any other Unixlike system.
805 * keyboard.c: Clarify a comment regarding the input loop.
807 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
808 functions directly instead of trying to detect at runtime that our
809 host operating system supports them. We make this change for two
810 reasons: Cygwin lacks support for the multibyte character
811 conversion functions used by the legacy menu code, and Cygwin
812 never needs to rely on non-Unicode APIs.
814 * unexw32.c (hinst): Declare extern.
816 * w32.c: Change header order;
817 (w32_strerror): Move to w32fns.c because we need it for
818 non-WINDOWSNT builds.
820 * w32.h: Add #error macro to make sure we don't include w32.h for
821 Cygwin builds. Remove w32select declarations.
823 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
824 w32fns.c. w32console.c is WINDOWSNT-only.
826 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
827 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
829 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
830 (w32_major_version, w32_minor_version, w32_build_number)
831 (os_subtype, sound_type): Define here
832 (w32_defined_color): Make color parameter const for consistency
833 with other _defined_color functions.
834 (w32_createwindow): Unconditionally call w32_init_class instead of
835 doing so only when hprevinst is non-NULL. Plumbing hprevinst
836 through the code is complex and unnecessary because class
837 registration is practically free.
838 (w32_name_of_message): New EMACSDEBUG-only function.
839 (Fset_message_beep): Move here
840 (Fx_open_connection): Require that the display name for Windows be
841 "w32" for consistency, emacsclient disambiguation, and maybe, one
842 day, multi-window-system support.
843 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
844 Cygwin files for W32 GUI facilities, since these clearly don't
847 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
848 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
849 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
850 (w32_last_error): Remove.
852 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
854 * w32heap.c (syspage_mask): Declare here.
855 (cache_system_info): Remove.
857 * w32inevt.c (faked_key): Define globally, not statically.
858 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
859 (w32_console_toggle_lock_key): Move to w32fns.c.
861 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
863 * w32proc.c (_DebPrint): Move to w32fns.c.
864 * w32select.c: Include string.h, stdio.h for Cygwin.
865 * w32select.h: New File.
867 * w32term.c: Include io.h for non-CYGWIN builds; needed for
869 (w32_message_fd): New variable. Under Cygwin, holds the file
870 descriptor the system used to tell us about pending thread
873 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
874 that prevented compilation under non-WINDOWSNT systems.
876 (w32_initialize): Open /dev/windows and assign it to
877 w32_message_fd. Provide w32 feature.
879 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
880 (WM_EMACS_INPUT_READY): add.
881 (prepend_msg, w32_message_fd): Declare globally.
884 (keyboard_handle): Use only when WINDOWSNT.
885 (notify_msg_ready): New function. Posts a message to the main
886 thread's message queue under CYGWIN, which wakes up the main
887 thread from select(2) by making the /dev/windows file descriptor
888 ready. Under WINDOWSNT, it sets an event the same way the old
891 (post, prepend_msg): Actually call notify_msg_ready instead of
892 setting the input event directly.
894 2012-10-07 Eli Zaretskii <eliz@gnu.org>
896 * ralloc.c (relinquish): If a heap is ready to be relinquished,
897 but it still has blocs in it, don't return it to the system,
898 instead of aborting. (Bug#12402)
900 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
902 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
904 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
905 MAC_OS_X_VERSION_10_6.

913 MAC_OS_X_VERSION_10_4.
915 * nsmenu.m (fillWithWidgetValue:): Remove code for <
916 MAC_OS_X_VERSION_10_2.
918 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
920 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
921 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
923 * nsterm.m (ns_in_resize): Remove (Bug#12479).
924 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
925 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
926 Remove ns_in_resize check.
927 (ns_clear_frame_area): Remove resize handle code.
929 * nsfns.m (ns_in_resize): Remove.
930 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
931 Remove ns_in_resize check.
933 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
935 Improve sys_siglist detection.
936 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
937 defined as a macro, as is done in Solaris.
938 (sys_siglist_entries): New macro.
939 (save_strsignal): Use it.
940 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
941 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
943 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
945 * nsfns.m (Fx_create_frame): Call x_default_parameter with
946 fullscreen/Fullscreen.

951 * nsterm.m (x_make_frame_visible): Check for fullscreen.
952 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
953 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
954 (windowDidResize:): Check for correct window if old style fullscreen.
955 Capitalize word in comment. Remove incorrect comment.
956 (initFrameFromEmacs:): tbar_height renamed tibar_height.
957 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
958 error in drawing background.
959 (toggleFullScreen:): Remove comment. Rearrange calls.
960 Set toolbar values to zero, save old height in tobar_height.
961 Restore tool bar height when leaving fullscreen.
962 (canBecomeMainWindow): New function.
964 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
966 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
968 2012-10-05 Eli Zaretskii <eliz@gnu.org>
970 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
972 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
973 that time stamps of directories could also be changed.
974 Don't request the too broad GENERIC_WRITE, only the more restrictive
975 FILE_WRITE_ATTRIBUTES access rights.
977 * fileio.c (Fset_file_times): Special-case ignoring errors for
978 directories only on MSDOS, not on MS-Windows.
980 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
982 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
984 2012-10-04 Eli Zaretskii <eliz@gnu.org>
986 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
987 see whether CreateFile failed.
989 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
991 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
992 to avoid similar races.
993 * keyboard.c (pending_signals): Now bool, not int.
995 Port timers to OpenBSD, plus check for timer failures.
996 OpenBSD problem reported by Han Boetes.
997 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
999 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1000 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1001 like OpenBSD, which has timer_settime but does not declare it.
1002 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1003 whether to use itimerspec-related primitives. All uses of
1004 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1006 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1008 * profiler.c (handle_profiler_signal): Fix a malloc race
1009 that caused Emacs to hang on Fedora 17 when profiling Lisp.
1011 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
1013 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1015 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1017 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1018 consistent with the change in return value of 'safe_strsignal'.
1020 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1022 Prefer plain 'static' to 'static inline' (Bug#12541).
1023 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1024 (bidi_set_sor_type, bidi_push_embedding_level)
1025 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

1030 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1031 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1032 Now 'static', not 'static inline'.
1034 Count overruns when profiling; change units to ns.
1035 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1036 Give extra weight to samples after overruns, to attempt to count
1037 the time more accurately.
1038 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1039 the underlying primitives nominally do ns.
1040 (Fprofiler_cpu_start): Document the change. Mention that
1041 the sampling intervals are only approximate.
1043 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1045 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

1048 case for the special 0 coding-system.
1050 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1051 (Fmake_overlay): Remove redundant tests.
1052 (fix_start_end_in_overlays): Remove redundant recentering.

1057 Update dependencies.
1059 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1061 Fix a malloc race condition involving strsignal.
1062 A signal can arrive in the middle of a malloc, and Emacs's signal
1063 handler can invoke strsignal, which can invoke malloc, which is
1064 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1065 Fix it by altering the signal handler so that it does not invoke
1067 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1068 * process.c (status_message): Use const pointer, in case strsignal
1069 is #defined to safe_strsignal.
1070 * sysdep.c (sys_siglist, init_signals): Always define and
1071 initialize a substitute sys_siglist if the system does not define
1072 one, even if HAVE_STRSIGNAL.
1073 (safe_strsignal): Rename from strsignal. Always define,
1074 using sys_siglist. Return a const pointer.
1075 * syssignal.h (safe_strsignal): New decl.
1076 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1078 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1080 * w32proc.c (timer_loop): Fix code that waits for timer
1081 expiration, to avoid high CPU usage.
1083 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1085 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1086 (sweep_weak_table): Remove redundant prototypes.
1088 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1090 * emacs.c: Move the inclusion of TERM_HEADER after including
1091 windows.h on WINDOWSNT. This avoids compilation problems with
1094 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1096 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1097 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1098 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1099 as the previous version used 'void *'.
1101 * ralloc.c (ROUNDUP): Fix last change.
1102 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1105 * w32proc.c <disable_itimers>: New static flag.
1106 (init_timers): Initialize it to zero, after creating the critical
1107 sections used by the timer threads.
1108 (term_timers): Set to 1 before deleting the critical sections.
1109 (getitimer, setitimer): If disable_itimers is non-zero, return an
1110 error indication without doing anything. Reported by Fabrice
1111 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1112 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1114 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1117 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1118 term_ntproc after all the other bookkeeping, to get timers working
1119 as long as possible.
1121 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1123 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1124 Suggested by Juri Linkov in
1125 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1127 Prefer plain 'static' to 'static inline' (Bug#12541).
1128 With static functions, modern compilers inline pretty well by
1129 themselves; advice from programmers often hurts as much as it helps.
1130 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1131 this change shrinks the text size of the Emacs executable by 1.1%
1132 without affecting CPU significantly in my benchmark.
1133 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

1213 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
1215 Revert the FOLLOW-SYMLINKS change for file-attributes.

1217 not enough time to get that tested before the freeze today.
1218 * dired.c (directory_files_internal, Ffile_attributes):

1255 * w32.c (init_environment, get_emacs_configuration): Support AMD64
1257 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
1258 compatibility with x64.
1260 * vm-limit.c (lim_data): Now size_t.
1261 (check_memory_limits): Adjust prototypes of real_morecore and
1262 __morecore to receive argument of type ptrdiff_t. Use size_t for

1288 * frame.c (x_report_frame_params): Use EMACS_UINT for the return
1289 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows
1292 * image.c (x_bitmap_pixmap): Return ptrdiff_t, not int, since

1316 sigfillset, and sigprocmask are no longer no-ops.
1317 (sigismember): New function.
1318 (struct itimer_data): New definition.
1319 (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)

1348 2012-09-30 Kenichi Handa <handa@gnu.org>
1350 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
1351 to the buffer relocation which may be caused by ccl_driver.

1405 Suggested by Eli Zaretskii in
1406 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
1408 2012-09-30 Eli Zaretskii <eliz@gnu.org>
1410 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
1411 HAVE_TIMER_SETTIME is defined.
1413 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
1415 Profiler improvements: more-accurate timers, overflow checks.
1416 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
1417 signal.h, setjmp.h. Include systime.h instead.
1418 (saturated_add): New function.
1419 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

1425 All uses changed to store the new value.
1426 (handle_profiler_signal): Rename from sigprof_handler_1,
1427 for consistency with other handlers. Do not check whether
1428 cpu_log is a hash-table if garbage collecting, since it
1429 doesn't matter in that case.
1430 (deliver_profiler_signal): Rename from sigprof_handler,
1431 for consistency with other handlers.
1432 (setup_cpu_timer): New function, with much of what used to be in
1433 Fprofiler_cpu_start. Check for out-of-range argument.
1434 Prefer timer_settime if available, and prefer
1435 thread cputime clocks, then process cputime clocks, then
1436 monotonic clocks, to the old realtime clock. Use make_timeval
1437 to round more-correctly when falling back to setitimer.
1438 (Fprofiler_cpu_start): Use it.
1439 (Fprofiler_cpu_stop): Prefer timer_settime if available.
1440 Don't assume that passing NULL as the 2nd argument of setitimer
1441 is the same as passing a pointer to all-zero storage.
1442 Ignore SIGPROF afterwards.
1443 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
1444 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
1445 non-fatal signal handlers. Ignore SIGPROF on startup.
1446 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
1447 in profiler.c, since sysdep.c now uses it.
1449 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
1450 Suggested by Eli Zaretskii in
1451 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

1464 (Fbacktrace_frame): Adjust accordingly.
1466 2012-09-28 Glenn Morris <rgm@gnu.org>
1468 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)
1469 (Frun_hook_with_args_until_failure): Doc fixes.

1503 * character.h (MAYBE_UNIFY_CHAR): Remove.
1504 * charset.c, charset.h (maybe_unify_char): Now static.
1505 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1506 Since this stuff is now private to charset.c, there's no need for
1507 a public macro and no need to inline by hand.

1538 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
1540 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
1542 Prefer POSIX timers if available.
1543 They avoid a race if the timer is too close to the current time.
1544 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
1545 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

1573 2012-09-25 Eli Zaretskii <eliz@gnu.org>
1575 * w32proc.c (sys_signal): Handle all signals defined by the
1576 MS-Windows runtime, not just SIGCHLD. Actually install the signal
1577 handlers for signals supported by Windows. Don't override
1578 term_ntproc as the handler for SIGABRT.
1579 (sigaction): Rewrite to call sys_signal instead of duplicating its
1581 (sys_kill): Improve commentary.
1583 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1584 consistency with a signature of a signal handler. All callers
1586 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1587 install term_ntproc as a signal handler for SIGABRT, as that
1588 should be done by the dumped Emacs.
1590 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
1592 * w32select.c (term_w32select): Protect against repeated
1593 invocation by setting clipboard_owner to NULL after calling

1608 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
1610 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
1611 when encountering an unknown bytecode.
1613 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
1615 image.c, indent.c: Use bool for booleans.
1616 * dispextern.h (struct image_type): Members valid_p, load, init
1617 now return bool, not int. All uses changed.
1618 * image.c: Omit unnecessary static decls.
1619 (x_create_bitmap_mask, x_build_heuristic_mask):
1620 Return void, not int, since callers don't care about the return value.

1655 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1657 Move pid_t related decls out of lisp.h.
1658 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1659 (interruptible_wait_for_termination):
1660 Move these decls from lisp.h to syswait.h, since they use pid_t.
1661 Needed on FreeBSD; see Herbert J. Skuhra in
1662 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1663 * callproc.c: Include syswait.h.

1683 Use bool for boolean.
1684 * gtkutil.c (xg_update_frame_menubar):

1709 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1711 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1712 fatal_error_backtrace.
1714 * w32proc.c (sys_kill): Undo last change: don't do anything when
1715 invoked to deliver SIGABRT to our own process. This is now
1716 handled by emacs_raise.
1718 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1720 * w32term.c (w32_read_socket): Remove leftover reference to
1721 interrupt_input_pending.
1723 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1725 Do not use SA_NODEFER.
1726 Problem reported by Dani Moncayo in
1727 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1729 * sysdep.c (emacs_abort): Do not reset signal handler.
1730 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1731 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1732 wanted even on POSIXish hosts, and it doesn't work on Windows.
1734 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1736 * xterm.c (x_term_init): Call fixup_locale before and after calling
1737 gtk_init (Bug#12392).
1739 2012-09-23 Chong Yidong <cyd@gnu.org>
1741 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
1742 Vdynamic_library_alist.
1744 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
1745 (Fgnutls_available_p): Caller changed.
1747 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
1748 (Flibxml_parse_xml_region): Likewise.
1750 * dispextern.h (struct image_type): Remove arg from init function.
1752 * image.c (Finit_image_library, lookup_image_type)
1753 (define_image_type): Remove now-unneeded second arg.
1754 (init_xpm_functions, init_png_functions, init_jpeg_functions)
1755 (init_tiff_functions, init_gif_functions, init_svg_functions):
1756 Arglist and w32_delayed_load calling convention changed.
1757 (gs_type): Remove init_gs_functions; there is no such function.
1758 (valid_image_p, make_image): Fix caller to lookup_image_type.
1760 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1762 Simplify and avoid signal-handling races (Bug#12471).
1764 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
1765 Avoid recursive loop if there's a fatal error in the function itself.
1766 * atimer.c (pending_atimers):
1767 * blockinput.h: Don't include "atimer.h"; no longer needed.
1768 (interrupt_input_pending): Remove. All uses removed.
1769 pending_signals now counts both atimers and ordinary interrupts.
1770 This is less racy than having three separate pending-signal flags.
1771 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
1773 Rename from their upper-case counterparts BLOCK_INPUT,
1774 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
1775 INPUT_BLOCKED_P, and turn into functions. All uses changed.
1776 This makes it easier to access volatile variables more accurately.
1777 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
1778 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
1779 that's more reliable if the code is buggy and sets
1780 interrupt_input_blocked to a negative value. All uses changed.
1781 * atimer.c (deliver_alarm_signal):
1782 Remove. No need to deliver this to the parent; any thread can
1783 handle this signal now. All uses replaced by underlying handler.
1784 * atimer.c (turn_on_atimers):
1785 * dispnew.c (handle_window_change_signal):
1786 * emacs.c (handle_danger_signal):
1787 * keyboard.c (kbd_buffer_get_event):
1788 Don't reestablish signal handler; not needed with sigaction.
1789 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
1791 Rework to avoid unnecessary accesses to volatile variables.
1792 (UNBLOCK_INPUT_TO): Now a function.
1793 (totally_unblock_input, unblock_input): New decls.
1794 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
1795 (init_data): Remove. Necessary stuff now done in init_signal.
1796 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
1797 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
1798 (fatal_error_code): Remove; no longer needed.
1799 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
1800 it doesn't always backtrace. All uses changed. No need to reset
1801 signal to default, since sigaction and/or die does that for us now.
1802 Use emacs_raise (FOO), not kill (getpid (), FOO).
1803 (main): Check more-accurately whether we're dumping.
1804 Move fatal-error setup to sysdep.c
1805 * floatfns.c: Do not include "syssignal.h"; no longer needed.
1806 * gtkutil.c (xg_get_file_name, xg_get_font):
1807 Remove no-longer-needed signal-mask manipulation.
1808 * keyboard.c, process.c (POLL_FOR_INPUT):
1809 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
1810 * keyboard.c (read_avail_input): Remove.
1811 All uses replaced by gobble_input.
1812 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
1813 (kbd_buffer_store_event_hold, gobble_input):
1814 (record_asynch_buffer_change) [USABLE_SIGIO]:
1815 (store_user_signal_events):
1816 No need to mess with signal mask.
1817 (gobble_input): If blocking input and there are terminals, simply
1818 set pending_signals to 1 and return. All hooks changed to not
1819 worry about whether input is blocked.
1820 (process_pending_signals): Clear pending_signals before processing
1821 them, in case a signal comes in while we're processing.
1822 By convention callers now test pending_signals before calling us.
1823 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
1824 New functions, to support changes to blockinput.h.
1825 (handle_input_available_signal): Now extern.
1826 (reinvoke_input_signal): Remove. All uses replaced by
1828 (quit_count): Now volatile, since a signal handler uses it.
1829 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
1830 All callers changed. Block SIGINT only if not already blocked.
1831 Clear sigmask reliably, even if Fsignal returns, which it can.
1832 Omit unnecessary accesses to volatile var.
1833 (quit_throw_to_read_char): No need to restore sigmask.
1834 * keyboard.c (gobble_input, handle_user_signal):
1835 * process.c (wait_reading_process_output):
1836 Call signal-handling code rather than killing ourselves.
1837 * lisp.h: Include <float.h>, for...
1838 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
1839 (pending_signals): Now volatile.
1840 (syms_of_data): Now const if IEEE floating point.
1841 (handle_input_available_signal) [USABLE_SIGIO]:
1842 (terminate_due_to_signal, record_child_status_change): New decls.
1843 * process.c (create_process): Avoid disaster if memory is exhausted
1844 while we're processing a vfork, by tightening the critical section
1846 (send_process_frame, process_sent_to, handle_pipe_signal)
1847 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
1849 (send_process): No need for setjmp/longjmp any more, since the
1850 SIGPIPE stuff is now gone. Instead, report an error if errno
1852 (record_child_status_change): Now extern. PID and W are now args.
1853 Return void, not bool. All callers changed.
1854 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
1855 Remove. All uses removed. This bug should be fixed now in a
1857 (wait_for_termination_1): Use waitpid rather than sigsuspend,
1858 and record the child status change directly. This avoids the
1859 need to futz with the signal mask.
1860 (process_fatal_action): Move here from emacs.c.
1861 (emacs_sigaction_flags): New function, containing
1862 much of what used to be in emacs_sigaction_init.
1863 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
1864 caught by emacs, to make races less likely.
1865 (deliver_process_signal): Rename from handle_on_main_thread.
1867 (BACKTRACE_LIMIT_MAX): Now at top level.
1868 (thread_backtrace_buffer, threadback_backtrace_pointers):
1870 (deliver_thread_signal, deliver_fatal_thread_signal):
1871 New functions, for more-accurate delivery of thread-specific signals.
1872 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
1873 (deliver_arith_signal): Handle in this thread, not
1874 in the main thread, since it's triggered by this thread.
1875 (maybe_fatal_sig): New function.
1876 (init_signals): New arg DUMPING so that we can be more accurate
1877 about whether we're dumping. Caller changed.
1878 Treat thread-specific signals differently from process-general signals.
1879 Block all signals while handling fatal error; that's safer.
1880 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
1882 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
1883 Ignore SIGPIPE unless batch.
1884 (emacs_backtrace): Output backtrace for the appropriate thread,
1885 which is not necessarily the main thread.
1886 * syssignal.h: Include <stdbool.h>.
1887 (emacs_raise): New macro.
1888 * xterm.c (x_connection_signal): Remove; no longer needed
1889 now that we use sigaction.
1890 (x_connection_closed): No need to mess with sigmask now.
1891 (x_initialize): No need to reset SIGPIPE handler here, since
1892 init_signals does this for us now.
1894 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
1896 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
1897 background rect may be larger (Bug#12245).
1899 2012-09-23 Chong Yidong <cyd@gnu.org>
1901 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
1903 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1905 * .gdbinit: Just stop at fatal_error_backtrace.
1906 See Stefan Monnier's request in
1907 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
1908 Remove no-longer-used query of system type.
1910 2012-09-22 Chong Yidong <cyd@gnu.org>
1912 * search.c (Freplace_match): Doc fix (Bug#12325).
1914 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
1916 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
1917 (Fline_end_position): Doc fix.
1919 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
1921 2012-09-22 Chong Yidong <cyd@gnu.org>
1923 * dispextern.h (struct image_type): Add new slot, storing a type
1924 initialization function.
1926 * image.c (define_image_type): Call the image initializer function
1927 if it is defined. Arguments and return value changed.
1928 (valid_image_p, make_image): Callers changed.
1929 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
1930 (gif_type, imagemagick_type, svg_type, gs_type):
1931 Add initialization functions.
1932 (Finit_image_library): Call lookup_image_type.
1933 (CHECK_LIB_AVAILABLE): Macro deleted.
1934 (lookup_image_type): Call define_image_type here, rather than via
1935 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
1936 (syms_of_image): Move define_image_type calls for xbm_type and
1937 pbm_type to lookup_image_type.
1939 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1941 * keyboard.c (timer_check_2): Move calculation of 'timers' and
1942 'idle_timers' from here ...
1943 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
1944 lists, to avoid infloops when the timer does something stupid,
1945 like reinvoke itself with the same or smaller time-out.
1948 2012-09-22 Martin Rudalics <rudalics@gmx.at>
1950 * window.c (Fsplit_window_internal): Handle only Qt value of
1951 Vwindow_combination_limit separately.
1952 (Qtemp_buffer_resize): New symbol.
1953 (Vwindow_combination_limit): New default value.
1956 2012-09-22 Eli Zaretskii <eliz@gnu.org>
1958 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
1959 the new overlay string. (Bug#10159)
1961 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
1963 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
1964 or that fprintf is async-signal-safe. POSIX doesn't require
1967 2012-09-22 Chong Yidong <cyd@gnu.org>
1969 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
1972 2012-09-22 Kenichi Handa <handa@gnu.org>
1974 * composite.c (composition_reseat_it): Handle the case that a
1975 grapheme cluster is not covered by a single font (Bug#12352).
1977 2012-09-21 Chong Yidong <cyd@gnu.org>
1979 * image.c (define_image_type): Avoid adding duplicate types to
1980 image_types (Bug#12463). Suggested by Jörg Walter.
1982 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1984 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
1985 (print_load_command_name): Add case LC_DATA_IN_CODE.
1986 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
1988 2012-09-21 Glenn Morris <rgm@gnu.org>
1990 * eval.c (Frun_hook_with_args_until_success)
1991 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
1993 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
1995 * fileio.c (Ffile_selinux_context): Only call freecon when
1996 lgetfilecon succeeded.
1997 (Fset_file_selinux_context): Likewise. (Bug#12444)
1999 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2001 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2002 reordering, locate the cursor by calling set_cursor_from_row; if
2003 that fails, clear the desired glyph matrix before returning a
2004 failure indication to the caller. Fixes leaving garbled display
2005 when fast scrolling with a down-key. (Bug#12403)
2006 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2007 scrolling through multibyte text.
2009 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2011 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2012 calling mark_vectorlike since that's the one that marks the window.
2013 (mark_discard_killed_buffers): Mark the final cdr.
2014 * window.h (struct window): Move prev/next_buffers to the
2015 non-standard fields.
2016 * window.c (make_window): Initialize prev/next_buffers manually.
2018 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2020 Omit unused arg EXPECTED from socket hooks.
2021 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2022 * nsterm.m (ns_term_init):
2023 * termhooks.h (struct terminal.read_socket_hook):
2024 * w32inevt.c (w32_console_read_socket):
2025 * w32term.c (w32_read_socket):
2026 * xterm.c (XTread_socket):
2027 Omit unused arg EXPECTED. All callers changed.
2028 (store_user_signal_events): Return void, not int, since callers no
2029 longer care about the return value. All uses changed.
2031 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2033 * w32gui.h (XParseGeometry): Do not declare.
2035 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2037 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2038 Ignore 'expected'. See Eli Zaretskii in
2039 <http://bugs.gnu.org/12471#8> (last line).
2041 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2042 (XParseGeometry): Now static. Substitute extremal values for
2043 values that are out of range.
2045 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2047 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2049 * nsfns.m (XParseGeometry): Remove.
2050 (Fx_create_frame): Call x_set_offset to correctly interpret
2051 top_pos in geometry.
2053 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2054 (Fx_parse_geometry): If there is a space in string, call
2055 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2057 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2059 * search.c (scan_buffer): Use character positions in calls to
2060 region_cache_forward and region_cache_backward, not byte
2061 positions. (Bug#12196)
2063 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2064 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2066 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2067 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2068 emacs_blocked_malloc, now deleted.
2070 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2072 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2073 The workaround was for improving performance on Solaris 2.4, but
2074 is getting in the way now. Emacs will still work if someone is
2075 still running Solaris 2.4 in a museum somewhere; Sun dropped
2076 support for Solaris 2.4 in 2003.
2077 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2078 * process.c (create_process) [HAVE_WORKING_VFORK]:
2079 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2080 since Emacs no longer uses vfork on that platform.
2082 2012-09-17 Glenn Morris <rgm@gnu.org>
2084 * emacs.c: Use COPYRIGHT.
2086 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2088 Remove configure's --without-sync-input option (Bug#12450).
2089 When auditing signal-handling in preparation for cleaning it up,
2090 I found that SYNC_INPUT has race conditions and would be a real
2091 pain to fix. Since it's an undocumented and deprecated
2092 configure-time option, now seems like a good time to remove it.
2093 Also see <http://bugs.gnu.org/11080#16>.
2094 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2095 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2096 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2097 (malloc_hysteresis):
2098 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2099 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2100 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2101 (dont_register_blocks, bytes_used_when_reconsidered)
2102 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2103 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2104 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2105 Remove. All uses removed.
2106 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2107 implementation, one that depends on whether the new macro
2108 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2110 * atimer.c (run_timers, handle_alarm_signal):
2111 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2112 (handle_async_input, process_pending_signals)
2113 (handle_input_available_signal, init_keyboard):
2114 * nsterm.m (ns_read_socket):
2115 * process.c (wait_reading_process_output):
2116 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2117 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2119 * xterm.c (XTread_socket):
2121 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2122 * eval.c (handling_signal): Remove. All uses removed.
2123 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2124 All uses replaced with the SYNC_INPUT version.
2125 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2127 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2130 * font.c (Ffont_shape_gstring): Remove unused local.
2132 2012-09-16 Glenn Morris <rgm@gnu.org>
2134 * Makefile.in (clean): No longer run nextstep's clean.
2136 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2138 (ns-app): Move here from ns.mk, and simplify.
2139 (clean): Simplify nextstep entry.
2140 * ns.mk: Remove file.
2142 2012-09-17 Kenichi Handa <handa@gnu.org>
2144 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2145 not covert the last few charactes.
2147 2012-09-16 Kenichi Handa <handa@gnu.org>
2149 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2150 here, but just check the validity of glyphs in the glyph-string.
2152 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2154 * window.c (Fwindow_parameter, Fset_window_parameter):
2155 Accept any window as argument (Bug#12452).
2157 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2159 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2160 to ns_term_init to avoid memory leak.
2162 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2163 explicit retain/release.
2164 (ns_term_init): Only allow one display. Initialize outerpool and
2167 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2169 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2170 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2171 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2172 the Microsoft problem in a different way, by altering ../nt/config.nt.
2174 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2189 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2190 by lisp.h. This completes removal of setjmp.h inclusion
2191 erroneously announced in the previous commit. (Bug#12446)
2193 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2196 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2197 not defined as a macro. The latter happens on MS-Windows.
2200 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2202 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2203 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2204 Some instances of '#include <setjmp.h>' removed, if the
2205 only reason for the instance was because "lisp.h" was included.
2206 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2207 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2208 and _longjmp with the new symbols. Emacs already uses _setjmp if
2209 available, so this change affects only POSIXish hosts that have
2210 sigsetjmp but not _setjmp, such as some versions of Solaris and
2211 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2212 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2213 (png_load_body) [HAVE_PNG]:
2214 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2215 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2216 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2217 since PNG requires jmp_buf. This is the only exception to the
2218 general rule that we now use sys_setjmp and sys_longjmp.
2219 This exception is OK since this code does not change the signal
2220 mask or longjmp out of a signal handler.
2222 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2224 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2225 Include "syssignal.h", for 'main_thread'.
2227 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2229 Avoid out-of-range marker position (Bug#12426).
2230 * insdel.c (replace_range, replace_range_2):
2231 Adjust markers before overlays, as suggested by comments.
2232 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2233 Remove redundant check before calling offset_intervals.
2235 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2237 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2238 current buffer (Bug#12387).
2240 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2242 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2244 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2246 Use a more backwards-compatible timer format (Bug#12430).
2247 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2248 vector element, not from the 4th, since PSECS is now at the end.
2249 (Fcurrent_idle_time): Doc fix.
2251 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2253 Function to mark objects and remove killed buffers at once.
2254 * alloc.c (discard_killed_buffers): Rename to ...
2255 (mark_discard_killed buffers) ... new name. Add marking
2256 of remaining objects. Fix comment. Adjust users.
2257 (mark_object): Do not touch frame buffer lists here.
2258 * frame.c (delete_frame): Reset frame buffer lists here.
2260 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2262 Better workaround for GNOME bug when --enable-gcc-warnings.
2263 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2264 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2265 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2267 Simplify SIGIO usage (Bug#12408).
2268 The code that dealt with SIGIO was crufty and confusing, e.g., it
2269 played tricks like "#undef SIGIO" but these tricks were not used
2270 consistently. Simplify mostly by not #undeffing standard symbols,
2271 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2272 or not as we please) rather than "defined SIGIO" (standard symbol
2273 that we probably shouldn't #undef).
2274 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2275 Modules that need it can include it.
2276 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2277 * dispextern.h (ignore_sigio): New decl.
2278 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2279 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2280 * emacs.c (shut_down_emacs):
2281 * keyboard.c (kbd_buffer_store_event_hold):
2282 Use ignore_sigio rather than invoking 'signal' directly.
2283 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2285 (FIONREAD, SIGIO): Do not #undef.
2286 (tty_read_avail_input): Use #error rather than a syntax error.
2287 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2288 for I_PIPE, used by SETUP_SLAVE_PTY.
2289 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2290 * sysdep.c (croak): Remove; no longer needed. This bit of
2291 temporary code, with Fred N. Fish's comment that it's temporary,
2292 has been in Emacs since at least 1992!
2293 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2294 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2295 * syssignal.h (croak): Remove decl.
2296 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2297 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2298 now that we're termios-only.
2299 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2300 * term.c (dissociate_if_controlling_tty): Use #error rather than
2303 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2304 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2305 to work around GNOME bug 683906.
2306 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2307 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2308 This works around GCC bug 54561.
2310 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2312 More fixes for 'volatile' and setjmp/longjmp.
2313 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2314 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2315 (png_load_body) [HAVE_PNG]:
2316 (jpeg_load_body) [HAVE_JPEG]:
2317 New function, with most of the old parent function's body.
2318 (png_load) [HAVE_PNG]:
2319 (jpeg_load) [HAVE_JPEG]:
2320 Invoke the new function, to avoid longjmp munging our locals.
2321 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2322 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2323 longjmp is passed 2, as the C standard doesn't guarantee this.
2324 Instead, store the failure code into mgr->failure_code.
2326 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2328 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2329 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2330 (syms_of_keyboard): Remove support for unread-command-char.
2332 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2334 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2335 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2336 violation. (Bug#12426)
2338 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2340 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2342 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2344 * eval.c: Add `inhibit-debugger'.
2345 (Qinhibit_debugger): New symbol.
2346 (call_debugger): Bind it instead of Qdebug_on_error.
2347 (maybe_call_debugger): Test Vinhibit_debugger.
2348 (syms_of_eval): Define inhibit-debugger.
2349 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2350 (syms_of_xdisp): Remove inhibit-debug-on-message.
2352 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2354 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2355 If a nonvolatile local variable is written before a _longjmp to
2356 the frame containing the variable, and is read after the _longjmp,
2357 the value read is indeterminate. Some local variables of type
2358 'struct handler' and 'struct catchtag' are used in this way, so
2359 mark each of their slots as volatile if the slot can be set before
2360 _longjmp and read afterwards.
2361 * lisp.h (struct handler): var and chosen_clause are now volatile.
2362 (struct catchtag): val, next, and pdlcount are now volatile.
2364 * bidi.c (bidi_push_it, bidi_pop_it):
2365 * fns.c (copy_hash_table):
2366 * image.c (define_image_type):
2367 * keyboard.c (kbd_buffer_store_event_hold):
2368 * process.c (Fprocess_send_eof):
2369 * xfaces.c (x_create_gc) [HAVE_NS]:
2370 * xgselect.c (xg_select):
2371 Prefer assignment to memcpy when either will do.
2373 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2374 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2375 time an item is removed. No need to mark this function 'inline';
2376 the compiler knows better than we do.
2378 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2380 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2381 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2382 to change_frame_size (Bug#12388).
2383 (windowDidResize:): Pass YES to updateFrameSize.
2385 * nsterm.h: Add delay parameter to updateFrameSize.
2387 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2389 Discard killed buffers from deleted window and frame objects.
2390 This reduces an amount of references to killed buffers and
2391 helps GC to reclaim them faster.
2392 * alloc.c (discard_killed_buffers): New function.
2393 (mark_object): Use it for deleted windows and frames.
2394 (mark_object): If symbol's value is set up for a killed buffer
2395 or deleted frame, restore its global binding.
2396 * data.c (swap_in_global_binding): Add GC notice.
2397 (swap_in_symval_forwarding): Use convenient set_blv_where.
2398 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2399 * window.h: ... to here.
2401 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2403 Convenient macro to check whether the buffer is live.
2404 * buffer.h (BUFFER_LIVE_P): New macro.
2405 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2406 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2408 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2410 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2411 composition cases (Bug#12364).
2413 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2414 overhang of succeeding glyphs overlapping box cursor.
2416 * w32term.c (x_draw_glyph_string): Likewise.
2418 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2420 Simplify, document, and port floating-point (Bug#12381).
2421 The porting part of this patch fixes bugs on non-IEEE platforms
2422 with frexp, ldexp, logb.
2423 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2425 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2426 support, by removing commented-out code and briefly listing the
2427 C89 functions excluded. The commented-out stuff was confusing
2428 maintenance, e.g., we thought we needed cbrt but it was commented out.
2429 (logb): Remove decl; no longer needed.
2430 (isfinite): New macro, if not already supplied.
2431 (isnan): Don't replace any existing macro.
2432 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2433 are present on all C89 platforms.
2434 (Ffrexp): Do not special-case zero, as frexp does the right thing
2436 (Flogb): Do not use logb, as it doesn't have the desired meaning
2437 on hosts that use non-base-2 floating point. Instead, stick with
2438 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2439 frexp, to avoid getting an unspecified result.
2441 * xdisp.c (Qinhibit_debug_on_message): Now static.
2443 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2445 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2446 NSBezierPath (Bug#12131).
2448 2012-09-10 Chong Yidong <cyd@gnu.org>
2450 * fns.c (Fdelq, Fdelete): Doc fix.
2452 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2454 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2455 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2457 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2459 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2460 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2463 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2465 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2466 left fringe if the window has a left margin. This avoids leaving
2467 traces of the cursor because its leftmost pixel is not drawn over.
2469 * dispnew.c (update_window_line): When the left margin area of a
2470 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2471 that screen line. (Bug#12277)
2473 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2475 Assume C89 or later for math functions (Bug#12381).
2476 This simplifies the code, and makes it a bit smaller and faster,
2477 and (most important) makes it easier to clean up signal handling
2478 since we can stop worring about floating-point exceptions in
2479 library code. That was a problem before C89, but the problem
2480 went away many years ago on all practical Emacs targets.
2481 * data.c, image.c, lread.c, print.c:
2482 Don't include <math.h>; no longer needed.
2483 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2484 might be autoconfigured, as that never happens.
2486 * doprnt.c (DBL_MAX_10_EXP):
2487 * print.c (DBL_DIG):
2488 Remove. C89 or later always defines these.
2489 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2490 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2491 (arith_error, domain_error, domain_error2):
2492 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2493 no longer needed -- we simply return what C returns. All uses removed.
2494 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2496 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2497 Remove. All uses expanded, as these macros are no longer used
2498 more than once and are now more trouble than they're worth.
2499 (Ftan): Use tan, not sin / cos.
2500 (Flogb): Assume C89 frexp.
2501 (fmod_float): Assume C89 fmod.
2502 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2503 (init_floatfns): Remove. All uses removed.
2505 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2507 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2508 compositeToPoint for OSX < 10.6 (Bug#12390).
2510 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2512 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2513 This produces more-accurate results.
2515 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2517 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2518 changes (Bug#12088).
2520 2012-09-08 Chong Yidong <cyd@gnu.org>
2522 * syntax.c (Fstring_to_syntax): Doc fix.
2524 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2526 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2527 in the internal border.
2528 (x_set_window_size): Remove static variables and their usage.
2529 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2530 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2531 Remove fringe/internal border adjustment (Bug#11052).
2532 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2533 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2534 (ns_fix_rect_ibw): Remove.
2535 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2536 (ns_dumpglyphs_box_or_relief): Ditto.
2537 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2539 (ns_dumpglyphs_image): Ditto.
2540 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2542 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2543 their usage. Add fringe_extended_p and its use as in other terms.
2544 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2545 scroll bar was removed.
2546 (updateFrameSize): New function.
2547 (windowDidResize): Move code to updateFrameSize and call it.
2549 * nsterm.h (EmacsView): Add updateFrameSize.
2551 2012-09-07 Chong Yidong <cyd@gnu.org>
2553 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2555 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2557 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2559 More signal-handler cleanup (Bug#12327).
2560 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2561 Problem introduced when merging patches. Noted by Eli Zaretskii in
2562 <http://bugs.gnu.org/12327#67>.
2563 * floatfns.c: Comment fix.
2564 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2565 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2566 and anyway the declaration is harmless even if SIGDANGER is not defined.
2567 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2568 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2569 source files not surprisingly expected syssignal.h to define, or
2570 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2571 Include <sys/ioctl.h>, for FIONREAD.
2572 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2573 This eliminates a problem whereby other files mysteriously had
2574 to include "syssignal.h" before including "systty.h" if they
2575 wanted to use "#ifdef SIGIO".
2577 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2579 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2581 * w32.c (sigemptyset): Empty the set.
2582 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2584 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2586 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2588 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2589 (mark_object): Likewise for frame objects.
2591 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2593 * syssignal.h (handle_on_main_thread): Always declare,
2594 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2595 This ports to platforms without HAVE_PTHREAD.
2597 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2599 Signal-handler cleanup (Bug#12327).
2600 Emacs's signal handlers were written in the old 4.2BSD style with
2601 sigblock and sigmask and so forth, and this led to some
2602 inefficiencies and confusion. Rewrite these to use
2603 pthread_sigmask etc. without copying signal sets around. Also,
2604 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2605 'signal', and instead use functions that do not attempt to take
2606 over the system name space. This patch causes Emacs's text
2607 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2608 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2609 Do not include <signal.h> or "syssignal.h", as these
2610 modules do not use signals.
2611 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2612 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2613 Do not include <signal.h>, as "syssignal.h" does that for us now.
2614 * atimer.c (sigmask_atimers): New function.
2615 (block_atimers, unblock_atimers): New functions,
2616 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2618 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2619 no longer needed here.
2620 * emacs.c (main): Inspect existing signal handler with sigaction,
2621 so that there's no need to block and unblock SIGHUP.
2622 * sysdep.c (struct save_signal): New member 'action', replacing
2623 old member 'handler'.
2624 (save_signal_handlers, restore_signal_handlers):
2625 Use sigaction instead of 'signal' to save and restore.
2626 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2627 New function. All users of 'signal' modified to use set_sighandler
2628 if they're writeonly, and to use sys_signal if they're read+write.
2629 (emacs_sigaction_init, forwarded_signal): New functions.
2630 (sys_signal): Remove. All uses replaced by calls to sigaction
2631 and emacs_sigaction_init, or by direct calls to 'signal'.
2632 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2633 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2634 all uses replaced by pthread_sigmask etc. calls.
2635 * syssignal.h: Include <signal.h>.
2636 (emacs_sigaction_init, forwarded_signal): New decls.
2637 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2638 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2639 (sigmask, sys_sigmask): Remove; no longer needed.
2640 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2641 (sigblock, sigunblock, sigfree):
2642 (sigsetmask) [!defined sigsetmask]:
2643 Remove. All uses replaced by pthread_sigmask.
2644 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2645 no longer need to be replaced, and its typical old uses
2646 are now done via emacs_sigaction_init and sigaction.
2647 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2648 (sys_sigdel): Remove; unused.
2649 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2651 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2653 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2654 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2656 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2658 Explicitly mark buffer_defaults and buffer_local_symbols.
2659 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2660 mark_local_symbols here.
2661 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2662 since special buffers aren't marked here any more.
2663 (allocate_buffer): Chain new buffer with all_buffers here...
2664 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2666 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2667 (syms_of_buffer): Remove staticpro of the above.
2668 (init_buffer_once): Set names for buffer_defaults and
2669 buffer_local_symbols.
2671 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2673 Use bool for booleans in font-related modules.
2674 * font.c (font_intern_prop, font_style_to_value)
2675 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2676 (generate_otf_features, font_check_otf_features, font_check_otf)
2677 (font_match_p, font_list_entities, font_at):
2678 * fontset.c (fontset_id_valid_p, reorder_font_vector
2679 (fontset_find_font, Fset_fontset_font)
2680 (face_suitable_for_char_p) [0]:
2681 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2682 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2683 (m17n_flt_initialized, ftfont_shape_by_flt):
2684 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2685 * nsfont.m (nsfont_draw):
2686 * w32font.c (w32font_draw):
2687 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2688 Use bool for booleans.
2689 * font.h: Adjust to above API changes.
2690 (struct font, struct font_driver, struct font_driver_list):
2691 Use bool for booleans.
2692 (struct font): Remove useless member encoding_type.
2694 * fontset.c, xftfont.c: Omit unnecessary static decls.
2696 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2698 * alloc.c (mark_object): Revert window marking code
2699 since it's unsafe for the Fset_window_configuration.
2701 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2703 Fix race conditions with signal handlers and errno (Bug#12327).
2704 Be more systematic about preserving errno whenever a signal
2705 handler returns, even if it's not in the main thread. Do this by
2706 renaming signal handlers to distinguish between signal delivery
2707 and signal handling. All uses changed.
2708 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2709 * data.c (deliver_arith_signal): Rename from arith_error.
2710 * dispnew.c (deliver_window_change_signal): Rename from
2711 window_change_signal.
2712 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2713 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2714 * keyboard.c (deliver_input_available_signal): Rename from
2715 input_available_signal.
2716 (deliver_user_signal): Rename from handle_user_signal.
2717 (deliver_interrupt_signal): Rename from interrupt_signal.
2718 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2719 (deliver_child_signal): Rename from sigchld_handler.
2720 * atimer.c (handle_alarm_signal):
2721 * data.c (handle_arith_signal):
2722 * dispnew.c (handle_window_change_signal):
2723 * emacs.c (handle_fatal_signal, handle_danger_signal):
2724 * keyboard.c (handle_input_available_signal):
2725 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2726 * process.c (handle_pipe_signal, handle_child_signal):
2727 New functions, with the actual signal-handling code taken from the
2728 original respective signal handlers, sans the sporadic attempts to
2729 preserve errno, since that's now done by handle_on_main_thread.
2730 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2731 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2732 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2734 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2735 Move initialization of main_thread to sysdep.c's init_signals.
2736 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
2737 our usage, and simplifies the mainline code.
2738 (record_child_status_change): New static function, as a helper
2739 for handle_child_signal, and with most of the old child handler's
2741 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
2742 (handle_child_signal): Use the above.
2743 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2744 Moved here from emacs.c.
2745 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
2746 code moved here from emacs.c's main function.
2747 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
2748 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
2749 This lets callers save and restore errno properly.
2751 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2753 Remove redundant or unused things here and there.
2754 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
2755 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
2756 * editfns.c (Fcompare_buffer_substrings): Likewise.
2757 * frame.h (struct terminal, struct font_driver_list):
2758 Remove redundant declarations.
2759 * window.h (Qleft, Qright): Likewise.
2761 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2763 Do not mark objects from deleted buffers, windows and frames.
2764 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
2765 (mark_object): Likewise for windows and frames.
2767 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
2769 * alloc.c (valid_lisp_object_p): Treat killed buffers,
2770 buffer_defaults and buffer_local_symbols as valid objects.
2771 Return special value to denote them.
2773 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2775 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
2776 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
2777 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
2778 (file_name_absolute_p, Fsubstitute_in_file_name):
2779 (check_executable, check_writable, Ffile_accessible_directory_p)
2780 (Fset_file_selinux_context, Fdefault_file_modes)
2781 (Finsert_file_contents, choose_write_coding_system)
2782 (Fwrite_region, build_annotations, a_write, e_write)
2784 * filelock.c (boot_time_initialized, get_boot_time)
2785 (get_boot_time_1, lock_file_1, within_one_second):
2786 * floatfns.c (in_float):
2787 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
2788 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
2789 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
2790 * lisp.h (struct Lisp_Hash_Table.cmpfn):
2791 * window.c (compare_window_configurations):
2792 Use bool for booleans.
2793 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
2794 (Fdefault_file_modes): Now mode_t, not int, for modes.
2795 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
2796 (internal_delete_file): Now returns void, not a (boolean) int,
2797 since nobody was looking at the return value.
2798 * lisp.h, window.h: Adjust to above API changes.
2800 * xdisp.c (set_message): Simplify and reindent last change.
2802 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
2804 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
2806 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
2808 * eval.c (call_debugger): Make the function non-static so that we
2809 can call it from set_message.
2811 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
2812 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
2814 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2816 Give more-useful info on a fatal error (Bug#12328).
2817 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
2818 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
2819 of doing the work ourselves.
2820 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
2821 do most of the work.
2822 (fatal_error_backtrace): New function, taken from the guts
2823 of the old fatal_error_signal, but with a new option to output
2825 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
2826 info about the signal than just its number.
2827 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
2828 * sysdep.c: Include <execinfo.h>
2829 (emacs_backtrace): New function, taken partly from the previous
2830 code of the 'die' function.
2831 (emacs_abort): Call fatal_error_backtrace rather than abort.
2833 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
2835 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
2836 eager (load-time) macro-expansion.
2837 * lisp.mk (lisp): Add macroexp.
2839 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2841 Simplify redefinition of 'abort' (Bug#12316).
2842 Do not try to redefine the 'abort' function. Instead, redo
2843 the code so that it calls 'emacs_abort' rather than 'abort'.
2844 This removes the need for the NO_ABORT configure-time macro
2845 and makes it easier to change the abort code to do a backtrace.
2846 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
2847 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
2848 Remove; sysdep.c's emacs_abort now takes its place.
2849 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
2850 'abort' changed to use 'emacs_abort'.
2851 * msdos.c (dos_abort) [defined abort]: Remove; not used.
2852 (abort) [!defined abort]: Rename to ...
2853 (emacs_abort): ... new name.
2854 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
2855 the place of the old 'abort' in emacs.c.
2856 * w32.c, w32fns.c (abort): Do not #undef.
2857 * w32.c (emacs_abort): Rename from w32_abort.
2859 2012-09-04 Eli Zaretskii <eliz@gnu.org>
2861 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
2862 offsets[j].dv, since the y axis of the screen coordinates points
2863 down, while the y axis of the font definition coordinates points
2864 up. This fixes display of Arabic diacritics such as KASRA and
2865 KASRATAN. (Bug#11860)
2867 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
2869 Be more systematic about _setjmp vs setjmp.
2870 * alloc.c (test_setjmp, mark_stack):
2871 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
2872 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
2873 (png_load, my_error_exit, jpeg_load):
2874 * process.c (send_process_trap, send_process):
2875 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
2876 The underscored versions are up to 30x faster on some hosts.
2877 Formerly, the code used setjmp+longjmp sometimes and
2878 _setjmp+_longjmp at other times, with no particular reason to
2879 prefer setjmp+longjmp.
2881 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
2883 Fix minor problem found by static checking.
2884 * buffer.c (Fdelete_all_overlays): Return nil.
2886 2012-09-03 Martin Rudalics <rudalics@gmx.at>
2888 * buffer.c (Fdelete_all_overlays): New function.
2890 2012-09-03 Chong Yidong <cyd@gnu.org>
2892 * gtkutil.c: Add extern decl for Qxft.
2894 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

2908 All callers changed.
2909 * eval.c (interactive_p): Omit always-true boolean argument
2910 EXCLUDE_SUBRS_P. All callers changed.
2911 * dispextern.h, lisp.h: Reflect above API changes.
2912 * firstfile.c (dummy): Use the address of 'main', whose signature
2913 won't change, instead of the address of 'initialize', whose
2914 signature just changed from int to bool.
2915 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
2916 * msdos.c (fatal_error_in_progress): ... from here.
2917 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
2919 (redisplay_internal, unwind_redisplay): Simply clear
2920 REDISPLAYING_P when unwinding, instead of saving its previous,
2921 always-false value and then restoring it.
2923 Clean up some extern decls.
2924 Mostly, this hoists extern decls out of .c files and into .h files.
2925 That way, we're more likely to catch errors if the interfaces change.
2926 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
2927 declare xg_mark_data.
2928 * dispextern.h (x_frame_parm_handlers):
2930 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

2946 * xfont.c (x_clear_errors):
2947 * xterm.c (x_frame_parm_handlers):
2948 Remove now-redundant extern decls.
2949 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
2950 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
2952 * xfaces.c: Remove unnecessary static decls.
2953 * xterm.c (updating_frame): Remove decl of nonexistent object.
2955 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
2956 when building globals.h, as the objects that are not built on
2957 this host are not needed to compile C files on this host.
2959 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
2961 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

2975 (make_buffer_string, make_buffer_string_both)
2976 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

2988 (set_intervals_multibyte_1, set_intervals_multibyte):
2989 * keyboard.c (decode_timer):
2990 Use bool for boolean.
2991 * intervals.h, lisp.h, systime.h: Reflect above API changes.
2992 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
2994 2012-09-02 Chong Yidong <cyd@gnu.org>
2996 * keymap.c (push_key_description): Print M-TAB as C-M-i
2999 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
3001 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
3002 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

3007 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
3009 2012-09-01 Eli Zaretskii <eliz@gnu.org>
3011 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3012 more than one grapheme cluster passed to the shaper: compute the
3013 offset adjustment values separately for each cluster. (Bug#11860)
3015 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3016 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3017 about implicit conversions from integer to pointer.
3019 2012-09-01 Daniel Colascione <dancol@dancol.org>
3021 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
3022 system used too early.
3024 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
3026 Better seed support for (random).

3055 * process.c: Include TERM_HEADER instead of listing all possible
3056 window-system headers.
3058 * nsterm.h: Remove declarations now in frame.h.
3059 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
3061 * menu.c: Include TERM_HEADER instead of listing all possible
3062 window-system headers.
3064 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
3067 * keyboard.c: Include TERM_HEADER instead of listing all possible
3068 window-system headers.
3070 * image.c: Include TERM_HEADER instead of listing all possible
3071 window-system headers. Declare Vlibrary_cache when compiling for
3074 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
3075 window system declarations.
3077 * frame.h: Move common functions here: set_frame_menubar,
3078 x_set_window_size, x_sync, x_get_focus_frame,
3079 x_set_mouse_position, x_set_mouse_pixel_position,
3080 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

3104 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3106 Remove mark_ttys function and fix tty_display_info initialization.
3107 * lisp.h (mark_ttys): Remove prototype.
3108 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
3109 to mark_ttys because all possible values of 'top_frame' slot are
3110 the frames which are reachable from Vframe_list.
3111 * term.c (mark_ttys): Remove.
3112 (init_tty): Safely initialize 'top_frame' slot with Qnil.
3114 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
3116 Change struct frame bitfields from unsigned char to unsigned.
3117 * frame.h (struct frame): Change type of 'display_preempted',

3119 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
3120 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
3121 bitfields from unsigned char to unsigned.

3134 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
3136 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
3137 for GCC 4.7.1 x86-64.
3139 2012-08-30 Glenn Morris <rgm@gnu.org>
3141 * lread.c (init_lread): For out-of-tree builds, only add the
3142 source directory's site-lisp dir to the load-path if it exists,
3143 consistent with in-tree builds. (Bug#12302)
3145 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
3147 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

3156 (addString:row:): Remove return self, declare return value as void.
3157 (addSplit): Remove return self, declare return value as void.
3158 (clicked:): Remove return self, declare return value as void.
3159 Set dialog_return to button_values[seltag]. Code formatting change.
3160 (initFromContents:isQuestion:): Adjust call to process_dialog.
3161 Code formatting change.
3162 (timeout_handler:): Set timer_fired to YES.
3163 (runDialogAt:): Set timer_fired to NO.
3164 Handle click on close button as quit.
3166 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3167 Add window_closed and button_values. Add void as return value for
3168 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3169 Add process_dialog as new member.
3171 2012-08-28 Eli Zaretskii <eliz@gnu.org>
3173 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
3174 is not one of the heaps we manage. (Bug#12242)

3235 Use bool for boolean.
3236 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
3237 and remove last int (actually boolean) argument, which was always 0.
3238 All callers changed.
3239 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
3240 * dispextern.h (struct composition_it): Use bool for boolean.
3241 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
3242 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
3243 * dired.c (file_name_completion):
3244 Use bool for boolean. (This was missed in an earlier change.)
3246 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3248 * window.c (Fset_window_configuration): Revert first part of
3251 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
3253 * nsterm.h (NSPanel): New class variable dialog_return.
3255 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
3256 Initialize dialog_return.
3257 (windowShouldClose:): Use stop instead of stopModalWithCode.
3258 (clicked:): Ditto, and also set dialog_return (Bug#12258).
3259 (timeout_handler:): Use stop instead of abortModal. Send a dummy
3261 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when

3306 Use bool for booleans.
3307 * coding.h, lisp.h: Reflect above API changes.
3308 * coding.c: Remove unnecessary static function decls.
3309 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
3310 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
3311 not a boolean 'int', since callers never look at the return value.
3312 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
3313 * coding.h (decoding_buffer_size, encoding_buffer_size)
3314 (emacs_mule_string_char): Remove unused extern decls.
3315 (struct iso_2022_spec, struct coding_system):

3317 (struct emacs_mule_spec): Remove unused field 'full_support'.
3318 All initializations removed.
3319 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
3321 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3323 Fix spare memory change (Bug#12286).
3324 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
3325 (valid_lisp_object_p): Likewise.
3327 2012-08-27 Martin Rudalics <rudalics@gmx.at>
3329 * window.c (Fset_window_configuration): Record any window's old
3330 buffer if it's replaced (see Bug#8789). If the new current
3331 buffer doesn't appear in the selected window, go to its old
3334 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
3336 Special MEM_TYPE_SPARE to denote reserved memory.
3337 * alloc.c (enum mem_type): New memory type.
3338 (refill_memory_reserve): Use new type for spare memory.
3339 This prevents live_cons_p and live_string_p from incorrect
3340 detection of uninitialized objects from spare memory as live.
3342 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
3345 * Makefile.in (.PHONY): versioclean -> versionclean.
3347 Remove unused external symbols.
3348 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
3349 * window.c (Qwindow_valid_p, decode_valid_window):
3350 Now static, not extern.
3351 * data.c (Qinterval): Remove; unused.
3352 (syms_of_data): Do not define 'interval'.
3353 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3354 * window.h (decode_valid_window):

3368 (map_sub_char_table):
3369 Use bool for boolean.
3370 * character.c (str_to_unibyte): Omit last boolean argument; it was
3371 always 0. All callers changed.
3372 * character.h, charset.h: Adjust to match previous changes.
3373 * character.h (char_printable_p): Remove decl of nonexistent function.
3374 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3375 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3376 are all boolean, so make them single-bit bitfields.
3378 * lisp.h (ASET): Remove attempt to detect side effects.
3379 It was meant to be temporary and it often doesn't work,
3380 because when IDX has side effects the behavior of IDX==IDX
3381 is undefined. See Stefan Monnier in
3382 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3384 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3386 * lisp.h (functionp): New function (extracted from Ffunctionp).
3387 (FUNCTIONP): Use it.
3388 * eval.c (Ffunctionp): Use it.
3390 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3392 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3393 as that's faster and simpler than static storage. Don't bother
3394 with the g_main_context_query overhead if g_main_context_pending
3395 says no events are pending.
3396 (gfds, gfds_size): Remove these static vars.
3397 (xgselect_initialize): Remove; no longer needed.
3398 All uses and decls removed.
3400 * emacs.c (fatal_error_signal_hook): Remove.
3401 All uses removed. This leftover from old code was always 0.
3403 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3404 * casefiddle.c (casify_object, casify_region):
3405 * casetab.c (set_case_table):
3406 * category.c, category.h (word_boundary_p):
3407 * category.h (CHAR_HAS_CATEGORY):
3408 Use bool for booleans, instead of int.
3410 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3412 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3414 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3416 On assertion failure, print backtrace if available.
3417 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3418 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3419 * Makefile.in (LIB_EXECINFO): New macro.
3422 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3423 * bytecode.c (exec_byte_code):
3424 * callint.c (check_mark, Fcall_interactively):
3425 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3426 (getenv_internal, sync_process_alive, call_process_exited):
3427 * lisp.h (USE_SAFE_ALLOCA):
3428 Use bool for booleans, instead of int.
3429 * lisp.h, process.h: Adjust prototypes to match above changes.
3430 * callint.c (Fcall_interactively): Don't assume the mark's
3431 offset fits in 'int'.
3433 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3435 * buffer.c, buffer.h: Use bool for boolean.
3436 * buffer.c (reset_buffer_local_variables)
3437 (buffer_lisp_local_variables, Fset_buffer_modified_p)

3441 (report_overlay_modification, call_overlay_mod_hooks):
3442 (mmap_enlarge, mmap_set_vars):
3443 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3444 Use bool for booleans, instead of int.
3445 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3446 since the 1-or-0 return value is always ignored anyway.
3447 (mmap_initialized_p):
3448 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3449 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3451 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3453 * bidi.c: Use bool for boolean.
3454 This is a bit more readable, and makes the text segment of bidi.o
3455 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3456 Presumably it's faster too.
3457 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3459 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3460 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
3461 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
3462 (bidi_explicit_dir_char, bidi_level_of_next_char)
3463 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3464 Use bool for booleans, instead of int.
3465 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3466 (bidi_unshelve_cache): Adjust decls to match code.
3468 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3470 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3473 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3475 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3476 * atimer.h: Include <stdbool.h>.
3478 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3480 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3481 compile time tests instead of run time tests on systems that do
3483 (FRAME_MAC_P): Remove leftover from deleted code.
3484 * frame.c (syms_of_frame): Remove leftover from deleted code.
3486 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3488 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3490 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3492 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3493 Otherwise, the compiler complains about (A?B:C) where B is void
3494 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3495 (fontset_add): Return void, for FONTSET_ADD.
3497 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3499 * alloc.c: Use bool for booleans.
3500 (gc_in_progress, abort_on_gc)
3501 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3502 (dont_register_blocks) [GC_MALLOC_CHECK]:
3503 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3504 (check_string_bytes, make_specified_string, memory_full)
3505 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3506 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3507 (mark_stack, valid_pointer_p, make_pure_string)
3508 (Fgarbage_collect, survives_gc_p, gc_sweep):
3509 Use bool for booleans, instead of int.
3510 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3511 Remove unused local.
3512 * alloc.c (PURE_POINTER_P):
3513 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3514 * editfns.c (Fformat):
3515 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3517 * fns.c (sweep_weak_table):
3518 * lisp.h (suppress_checking, push_message, survives_gc_p)
3519 (make_pure_string, gc_in_progress, abort_on_gc):
3520 * lread.c (readchar, read1):
3521 * print.c (Fprin1_to_string):
3522 * xdisp.c (push_message):
3523 Use bool for booleans affected directly or indirectly by
3526 Make recently-introduced setters macros.
3527 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3528 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3529 (set_fontset_default, set_fontset_fallback): Rename from their
3530 upper-case counterparts, and make them functions rather than macros.
3531 This is more consistent with the other recently-introduced setters.
3532 These don't need to be inline, since they're local.
3534 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3536 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3537 the loop (Bug#12247).
3539 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3541 * lisp.h (vcopy): Use memcpy rather than our own loop.
3542 This fixes a performance regression introduced by the recent
3543 addition of vcopy. This means 'vcopy' will need to be modified
3544 for a copying collector, but that's OK. Also, tighten the
3545 checking in the assertion.
3547 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3549 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3550 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3551 non-base glyph for the width of the base character, according to
3552 what x_draw_composite_glyph_string_foreground expects.
3553 Generate WADJUST value according to composition_gstring_width's
3554 expectations, to produce correct width of the composed character.
3555 Reverse the sign of the DU offset produced by ScriptPlace.
3557 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3559 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3561 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3563 Avoid direct writes to contents member of struct Lisp_Vector.
3564 * lisp.h (vcopy): New function to copy data into vector.
3565 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3566 * fns.c (Ffillarray): Use ASET.
3567 * keyboard.c (timer_check_2): Use AREF and ASET.
3568 (append_tool_bar_item, Frecent_keys): Use vcopy.
3569 * lread.c (read_vector): Use ASET.
3570 * msdos.c (Frecent_doskeys): Use vcopy.
3571 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3572 (Finternal_merge_in_global_face): Use ASET and vcopy.
3573 * xfont.c (xfont_list_pattern): Likewise.
3575 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3577 * window.c (Fwindow_point): For the selected window always return
3578 the position of its buffer's point.
3579 (Fset_window_point): For the selected window always go in its
3580 buffer to the specified position.
3582 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3584 Setter macros for fontsets.
3585 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3586 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3587 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3590 2012-08-20 Glenn Morris <rgm@gnu.org>
3592 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3593 Don't assume that `ln -f' works.
3595 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3597 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3598 and later about non-assignments with no effect. See discussion at
3599 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3602 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3604 Inline setter functions for Lisp_Objects slots of struct specbinding.
3605 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3608 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3610 * window.c (select_window): Always make selected window's buffer
3613 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3615 Use AREF and ASET for docstrings of category tables.
3616 * category.h (CATEGORY_DOCSTRING): Use AREF.
3617 (SET_CATEGORY_DOCSTRING): Use ASET.
3618 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3620 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3622 Inline setter functions for hash table members.
3623 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3624 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3625 (set_hash_key_and_value, set_hash_index, set_hash_next)
3626 (set_hash_hash): New functions.
3627 * charset.c, fns.c: Adjust users.
3629 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3631 Inline getter and setter functions for per-buffer values.
3632 * buffer.h (per_buffer_default, set_per_buffer_default)
3633 (per_buffer_value, set_per_buffer_value): New functions.
3634 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
3635 * buffer.c, data.c: Adjust users.
3637 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3639 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3641 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3643 Rely on <config.h> + <unistd.h> to declare 'environ',
3644 as gnulib does this if the system doesn't.
3645 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3646 Remove declaration. MS-Windows declares it on stdlib.h which is
3647 included by conf_post.h.
3648 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3649 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.

3655 * xdisp.c (handle_invisible_prop): Make it a bit faster
3656 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3658 2012-08-19 Chong Yidong <cyd@gnu.org>

4069 Use bool, not int, for Lisp booleans.

4521 value of EMACSLOADPATH, as it is no longer needed.
4522 (check_windows_init_file): Now external, not static.
4523 Use Vload_path as is, without adding anything, as this function is now
4524 called when Vload_path is already set up.
4526 * w32.h (check_windows_init_file): Add prototype.
4528 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
4529 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
4530 compatibility with Posix platforms.
4531 (main): Move the call to check_windows_init_file to here from
4533 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
4534 any, in the DEFALT argument into the root of the Emacs build or
4535 installation tree, as appropriate.
4537 * callproc.c (init_callproc_1): Call decode_env_path instead of
4538 doing its equivalent by hand.
4539 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
4540 the code that sets Vexec_path run on MS-Windows.
4542 * lread.c (init_lread): Add comments to #ifdef's.
4544 * msdos.c (dos_set_window_size, IT_update_begin)
4545 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
4546 instead of direct references.
4548 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
4550 Export DEFAULT_REHASH_* to GDB.
4551 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
4552 Now constants, not macros.
4554 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
4556 Remove unnecessary casts involving pointers.
4557 These casts are no longer needed now that we assume C89 or later,
4558 since they involve casting to or from void *.
4559 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
4560 (make_pure_float, make_pure_vector):
4561 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

4569 * xselect.c (x_stop_queuing_selection_requests)
4570 (x_get_window_property, x_get_window_property_as_lisp_data):
4571 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4572 Remove unnecessary pointer casts.
4573 * alloc.c (record_xmalloc): New function.
4574 * lisp.h (record_xmalloc): New decl.
4575 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4576 more like a function. This is because the pointer cast is not
4577 needed. All uses changed.
4578 * print.c (print_string, print_error_message): Avoid length recalc.
4580 Improve fix for macroexp crash with debugging (Bug#12118).
4581 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4582 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4583 not supposed to be invoked from the garbage collector.
4584 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4585 (gc_aset): New function, which is like ASET but can be
4586 used in the garbage collector.
4587 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
4588 (set_hash_index): Use it instead of ASET.

4597 <g_b_init_create_symbolic_link>: New static flags.
4598 (globals_of_w32): Initialize them to zero.
4599 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
4600 (map_w32_filename): Improve commentary. Simplify switch.
4601 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
4602 headers (most versions of MinGW w32api don't).
4603 (get_security_info, create_symbolic_link)
4604 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
4606 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
4607 in the argument file name.
4608 (sys_access): Call unc_volume_file_attributes only if
4609 GetFileAttributes fails with network-related error codes.
4610 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4611 have the required privileges.
4612 (get_file_security_desc_by_name): Rename from
4613 get_file_security_desc.
4614 (stat_worker): New function, with most of the guts of 'stat', and
4615 with addition of handling of symlinks and support for 'lstat'.
4616 If possible, get file's attributes and security information by
4617 handle, not by name. Produce S_IFLNK bit for symlinks, when
4618 called from 'lstat'.
4619 (stat, lstat): New functions, call 'stat_worker'.
4620 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4621 symlinks when the underlying filesystem supports them.
4623 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4625 Fix macroexp crash on Windows with debugging (Bug#12118).
4626 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4627 checking subscripts; problem introduced with the recent
4628 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4629 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4630 since it's used in non-static inline functions now.
4632 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4633 Don't assume buffer size fits in 'int'. Remove unused local.
4635 Use C99-style 'extern inline' if available.

4646 * dispextern.h, lisp.h, systime.h:
4647 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4648 * alloc.c (LISP_INLINE):
4649 * buffer.c (BUFFER_INLINE):
4650 * category.c (CATEGORY_INLINE):
4651 * character.c (CHARACTER_INLINE):
4652 * charset.c (CHARSET_INLINE):
4653 * composite.c (COMPOSITE_INLINE):
4654 * dispnew.c (DISPEXTERN_INLINE):
4655 * sysdep.c (SYSTIME_INLINE):
4656 Define to EXTERN_INLINE, so that the corresponding functions
4657 are compiled into code.
4658 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4659 (INLINE_HEADER_END): New macros.
4660 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4680 hard-coding the path separator.
4682 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4684 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4685 This how ASET and AREF are supposed to work, and makes
4686 it easier to think about future improvements. See
4687 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4688 * charset.h (set_charset_attr): New function.
4689 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
4690 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

5103 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
5104 enumeration constants, as PURE and HEAP are too general, and clash
5105 with other headers and sources, such as gmalloc.c and the
5106 MS-Windows system headers. All users changed.
5108 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5110 Revert last save_excursion_save and save_excursion_restore changes.
5111 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

5124 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5125 arms of an 'if', not using conditional expressions; otherwise GDB
5126 complains about the types in the unevaluated arm when the argument
5127 is an integer literal.
5128 (xgetint): Simplify expression.
5129 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5130 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5131 Zaretskii in <http://bugs.gnu.org/12036#13>.
5132 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5133 needed now that we have gdb_make_enums_visible.
5134 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5135 (enum enum_USE_LSB_TAG):
5136 New enum types, packaging up enums that need to be exported to GDB.

5178 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5179 emacs.c, as this is a more-suitable home. Had this been done earlier
5180 the fix for 12036 would have avoided some of the problems noted in
5181 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5182 would have been more obvious.
5183 * emacs.c: Do not include <verify.h>; no longer needed.
5184 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5185 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5186 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

5192 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5193 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5194 not be usable in #if. This simplifies things.
5196 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5198 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

5203 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5204 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5205 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5206 Adjust to changes in lisp.h and emacs.c, by using
5207 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5208 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5209 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5210 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5211 instead of gdb_valbits.
5212 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5213 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5214 instead of gdb_array_mark_flag.
5215 (xboolvector): Get size from $->size, not $->header.size.
5216 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5217 (xreload, hook-run, hookpost-run): Remove.
5218 * emacs.c: Include <verify.h>.
5219 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5220 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5222 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5223 (gdb_USE_LSB_TAG): New enum constants.
5224 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5225 Also define these as enum constants, so they're visible to GDB.
5226 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5227 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5228 as constants, so they're visible to GDB.

5231 Now enum constants, not macros, so they're visible to GDB.
5232 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5233 more convenient now. All uses changed.
5234 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5235 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5237 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

5244 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5245 add argument, tune behavior, and adjust all callers.
5247 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5249 Use typedef for EMACS_INT, EMACS_UINT.
5250 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5251 than macros. This simplifies debugging in the usual case, since
5252 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5253 and it allows expressions involving EMACS_INT casts.
5254 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5256 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

5268 Adjust buffer text indirection counters at the end of Fkill_buffer.
5269 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5270 buffer is definitely dead. This should really fix an issue reported
5271 by Christoph Scholtes again. (Bug#12007).
5272 (init_buffer_once): Initialize indirection counters of
5273 buffer_defaults and buffer_local_symbols (for sanity and safety).
5275 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5277 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5278 and continuation glyphs on tooltip frames, leave them at zero.

5306 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5308 Swap buffer text indirection counters in Fbuffer_swap_text.
5309 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5310 This avoids crash reported by Christoph Scholtes at
5311 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5313 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5315 * nsmenu.m (Popdown_data): New struct.
5316 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
5318 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
5319 (initWithContentRect): Make imgView and contentView non-static
5320 and autorelease them. Also autorelease img and matrix (Bug#12005).
5321 (dealloc): Remove (Bug#12005).
5323 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
5325 Adjust consing_since_gc when objects are explicitly freed.

5338 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
5340 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
5341 as it's limited by the amount of memory, not by INT_MAX.
5343 2012-07-21 Eli Zaretskii <eliz@gnu.org>
5345 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
5346 in special-event-map. See the discussion at

6071 EMACS_TIME simplification (Bug#11875).
6072 This replaces macros (which typically do not work in GDB)

6074 The functional style also makes code easier to read and maintain.
6075 * systime.h: Include <sys/time.h> on all hosts, not just if
6076 WINDOWSNT, since 'struct timeval' is needed in general.

6089 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
6090 not functions. All uses rewritten to use the following, respectively:
6091 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
6092 (add_emacs_time, sub_emacs_time): New functions.
6093 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

6116 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6117 Prefer snprintf to strncpy.
6118 * nsterm.m (ns_term_init):
6119 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6120 * nsterm.m (ns_term_init):
6121 Avoid the need for strncpy, by using build_string or
6122 make_unibyte_string directly. Use dtoastr, not snprintf.
6123 * process.c (Fmake_network_process): Diagnose service names that
6124 are too long, rather than silently truncating them or creating
6125 non-null-terminated names.

6135 Clarify fallback case.
6137 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>

6141 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
6142 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
6143 where argument type is known to be a Lisp_Cons.

6198 O_RDONLY already includes it).
6200 Stop ns builds setting the EMACSLOADPATH environment variable.
6201 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6202 Now it does not set EMACSLOADPATH, just returns the load-path string.

6204 * lread.c [HAVE_NS]: Include nsterm.h.
6205 (init_lread) [HAVE_NS]: Use ns_load_path.

6215 (ns_init_paths): Do not set EMACSPATH.

6302 * xdisp.c (display_line): Avoid warning about implicit declaration
6305 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6307 * lisp.h: Remove empty conditional.
6309 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6311 * lread.c (load_path_check): Now static.
6313 Fix some minor --with-ns problems found by static checking.
6314 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6315 (x_set_font) [!HAVE_X_WINDOWS]:
6316 * image.c (xpm_load_image) [HAVE_NS]:
6317 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6318 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6319 Remove unused local.
6320 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6321 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6322 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6323 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6324 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6325 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6326 Fix pointer signedness problem.
6327 * xfaces.c (FRAME_X_FONT_TABLE):
6328 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6330 2012-07-07 Glenn Morris <rgm@gnu.org>
6332 * lread.c (load_path_check): New function, split from init_lread.
6333 (init_lread): Reorganize. Motivation:
6334 If EMACSLOADPATH is set, check/warn about that rather than the
6335 defaults, which we are not going to use. Hence we can remove
6336 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6337 Don't warn if site-lisp directories are missing.
6338 If not installed, start from a blank load-path, since
6339 PATH_LOADSEARCH refers to the eventual installation directories.
6341 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6343 Support truncation and continuation glyphs on GUI frames, when
6344 fringes are disabled. (Bug#11832)
6345 * xdisp.c (init_iterator): Get dimensions of truncation and
6346 continuation glyphs even if on GUI frames.
6347 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6348 or both, are absent.
6349 (start_display, move_it_in_display_line_to): Handle the case of a
6350 GUI frame without a fringe to display continuation or truncation
6352 (insert_left_trunc_glyphs): Support GUI frames: make sure
6353 truncation glyphs overwrite enough glyphs from the current line to
6354 have sufficient space in pixels.
6355 (display_line): Support truncation and continuation glyphs on GUI
6356 frames. If some spare pixels are left on the line after inserting
6357 the truncation glyphs, fill that space with a stretch glyph of a
6358 suitably computed width.
6360 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6361 produce_glyphs, to support GUI sessions.
6363 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6365 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6367 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6369 Do not require float-time's arg to fit in time_t (Bug#11825).
6370 This works better on hosts where time_t is unsigned, and where
6371 float-time is applied to the (negative) difference between two times.
6372 * editfns.c (decode_time_components): Last arg is now double *,
6373 not int *, and means to store all the result as a double, without
6374 worrying about whether the seconds part fits in time_t.
6375 All callers changed.
6376 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6377 All callers changed.
6378 (Ffloat_time): Do not fail merely because the specified time falls
6379 outside of time_t range.
6381 2012-07-07 Glenn Morris <rgm@gnu.org>
6383 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
6384 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

6387 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
6389 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
6390 Update dependencies.
6392 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6394 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6396 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
6397 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
6398 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6399 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6400 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6401 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6403 * xfont.c (compare_font_names): Redo to omit the need for casts.
6405 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6407 * xfns.c (Fx_change_window_property): Doc fix.
6408 * w32fns.c (Fx_change_window_property): Doc fix.
6410 * w32fns.c (Fx_window_property): Accept the same arguments as the
6411 X Windows version. Doc fix.
6412 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6414 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6415 Eli Zaretskii <eliz@gnu.org>
6417 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6418 Windows-specific code from nt/config.nt moved here.
6419 Obsolete settings removed.
6421 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6423 * process.c: Avoid unnecessary calls to gettime.
6424 (wait_reading_process_output): Don't get the time of day
6425 when gobbling data immediately and not waiting, as there's no need
6426 for it in that case. This removes a FIXME.
6428 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6430 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6431 is defined (Bug#11768).
6433 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6435 Fix marker debugging code.
6436 * marker.c (byte_char_debug_check): Do not perform the check
6437 if buffer is not multibyte.
6438 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6439 Call byte_char_debug_check with correct arguments.
6441 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6443 Compile marker debugging code only if ENABLE_CHECKING is defined.
6444 * marker.c (byte_char_debug_check, count_markers):
6445 Use only if ENABLE_CHECKING is defined.
6446 (byte_debug_flag): Remove.
6447 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6448 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6450 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6452 Avoid code repetition in marker-related functions.
6453 * marker.c (attach_marker): New function.
6454 (Fset_marker, set_marker_restricted, set_marker_both)
6455 (set_marker_restricted_both): Use it.
6456 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6457 Consistently rename charno to charpos.
6458 (marker_position): Add eassert.
6459 (marker_byte_position): Convert to eassert.
6461 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6463 Simplify list operations in unchain_overlay and unchain_marker.

6465 * marker.c (unchain_marker): Simplify. Fix comments.
6467 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6469 Introduce fast path for the widely used marker operation.
6470 * alloc.c (build_marker): New function.
6471 * lisp.h (build_marker): New prototype.
6472 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6473 * composite.c (autocmp_chars): Likewise.
6474 * editfns.c (buildmark): Remove.
6475 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6476 (save_restriction_save): Use build_marker.
6477 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6478 * window.c (save_window_save): Likewise.
6480 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6482 Do not use Fdelete_overlay in delete_all_overlays
6483 to avoid redundant calls to unchain_overlay.
6484 * buffer.c (drop_overlay): New function.
6485 (delete_all_overlays, Fdelete_overlay): Use it.
6486 * minibuf.c (get_minibuffer): Fix comment.
6488 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6490 Port to OpenBSD 5.1 amd64.
6491 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6492 This is needed for OpenBSD, and should be harmless on all BSD systems.
6493 Also, include <sys/sysctl.h>, as it should be available on all
6494 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6495 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6496 use p_pid member, not kp_proc.pid.
6498 2012-07-06 Glenn Morris <rgm@gnu.org>
6500 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6502 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6504 More xmalloc and related cleanup.
6505 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6506 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
6507 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

6509 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
6510 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:
6511 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
6512 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6513 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6515 Omit needless casts involving void * pointers and allocation.
6516 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6517 as the former is more robust if P's type is changed.
6518 Prefer xzalloc to xmalloc + memset 0.
6519 Simplify malloc-or-realloc to realloc.
6520 Don't worry about xmalloc returning a null pointer.
6521 Prefer xstrdup to xmalloc + strcpy.
6522 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6524 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6525 alloca of a constant.
6527 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6529 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6530 hscroll is larger than the line width. Fixes long and futile
6531 looping inside extend_face_to_end_of_line (on a TTY) producing
6532 glyphs that are not needed and thrown away.
6534 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6536 * marker.c (set_marker_restricted_both): Simplify by using
6539 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6541 * editfns.c (region_limit): Simplify by using clip_to_bounds.
6543 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

6546 not defined (Bug#11768).
6547 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
6548 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6549 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6550 followed by gtk_box_set_homogeneous (Bug#11768).
6551 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6552 (update_theme_scrollbar_width, xg_create_scroll_bar):
6553 Use gtk_scrollbar_new (Bug#11768).
6554 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6555 (is_box_type): New function (Bug#11768).
6556 (xg_tool_item_stale_p): Call is_box_type.
6557 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6558 with default display (Bug#11768).
6560 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6562 * xdisp.c (window_hscroll_limited): New function.
6563 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6564 coordinates when window's hscroll is set to insanely large
6567 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6569 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6570 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6572 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6575 * lisp.h (xzalloc): New prototype. Omit needless casts.
6576 * alloc.c (xzalloc): New function. Omit needless casts.
6577 * charset.c: Omit needless casts. Convert all calls to
6578 xmalloc with following memset to xzalloc.
6579 * dispnew.c: Likewise.
6580 * fringe.c: Likewise.
6581 * image.c: Likewise.

6628 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6630 * fileio.c (time_error_value): Check the right error number.
6631 Problem reported by Troels Nielsen in
6632 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6634 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6636 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6637 This should be fixed in a better way; see Eli Zaretskii in
6638 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6639 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6641 * fileio.c (time_error_value): Rename from special_mtime.
6642 The old name's problems were noted by Eli Zaretskii in
6643 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6645 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6646 This variable's comment says Emacs needs at least one GDB-visible
6647 symbol of type enum pvec_type, to work around GDB problems.
6648 The symbol's value doesn't matter.
6650 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6651 that causes compilation to fail on pre-C99 compilers.
6653 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6655 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6656 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6658 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6660 * buffer.c (init_buffer_once): Fix initialization of
6661 headers for buffer_defaults and buffer_local_symbols.
6662 Reported by Juanma Barranquero <lekktu@gmail.com>.
6664 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6666 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6667 * lisp.h (enum pvec_type): Use fewer bits.
6668 (PSEUDOVECTOR_SIZE_BITS): New constant.
6669 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6670 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6671 change in pvec_type.
6672 (PSEUDOVECTOR_TYPEP): New macro.
6673 (TYPED_PSEUDOVECTORP): Use it.
6674 * fns.c (internal_equal): Adapt code to extract pvectype.
6675 * emacs.c (gdb_pvec_type): Update type.
6676 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
6677 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
6678 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6679 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6680 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6681 abusing vector->header.next.nbytes.
6682 (live_vector_p): Use PVEC_TYPE.
6683 (mark_object): Adapt code to extract pvectype. Use switch.
6685 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6687 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6688 Tighten new eassert a bit.
6690 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6692 Fix compilation with --enable-gcc-warnings and -O1
6694 * doprnt.c (doprnt): Change type of tem to int, initialize
6695 to avoid compiler warning. Add eassert.
6696 * search.c (simple_search): Initialize match_byte to avoid
6697 compiler warning. Add eassert.
6699 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6701 Avoid weird behavior with large horizontal scrolls.
6702 Without this change, for example, large hscroll values would
6703 mess up Emacs's display on Fedora 15 x86, presumably due to
6704 overflows in int calculations in the display code.
6705 Also, if buffers had long lines, Emacs would freeze.
6706 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6707 (set_window_hscroll): New function, containing the old guts of
6708 Fset_window_hscroll. Return the clipped value.
6709 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6710 This avoids the need to check against PTRDIFF_MAX.
6712 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6714 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6716 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6718 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6720 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6721 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6722 since GCC 4.4.6 issues a bogus warning for them.
6724 Fix bugs in file timestamp newness comparisons.
6725 * fileio.c (Ffile_newer_than_file_p):
6726 * lread.c (Fload): Use full timestamp resolution of files,
6727 not just the 1-second resolution, so that files that are only
6728 slightly newer still count as newer.
6729 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6730 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6732 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6734 * fileio.c: Improve handling of file time marker. (Bug#11852)
6735 (special_mtime): New function.
6736 (Finsert_file_contents, Fverify_visited_file_modtime):
6737 Use it to set special mtime values consistently.
6739 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
6741 * fileio.c (Finsert_file_contents): Properly handle st_mtime
6742 marker for non-existing file. (Bug#11852)
6744 2012-07-03 Glenn Morris <rgm@gnu.org>
6746 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
6747 and did not make it into globals.h).
6749 2012-07-03 Tom Tromey <tromey@redhat.com>
6751 * window.c (Fset_window_margins, Fset_window_fringes)
6752 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
6753 * textprop.c (Fprevious_property_change): No longer static.
6754 * syntax.c (Fsyntax_table_p): No longer static.
6755 * process.c (Fget_process, Fprocess_datagram_address): No longer

6795 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
6796 values which aren't power of 2.
6797 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
6798 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users

6807 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6809 * alloc.c (allocate_vector_block): Remove redundant
6810 calls to mallopt if DOUG_LEA_MALLOC is defined.
6811 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
6812 avoid calls to mallopt if zero_vector is returned.
6814 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6816 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
6817 is enabled, avoid dereferencing NULL current_sblock if
6820 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
6822 Cleanup basic buffer management.
6823 * buffer.h (struct buffer): Change layout to use generic vector
6824 marking code. Fix some comments. Change type of 'clip_changed'
6825 to bitfield. Remove unused #ifndef old.
6826 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
6827 (GET_OVERLAYS_AT): Fix indentation.
6828 (for_each_per_buffer_object_at): New macro.

6832 * alloc.c (allocate_buffer): Adjust to match new layout of
6833 struct buffer. Fix comment.
6834 (mark_overlay): New function.

6836 Lisp area of struct buffer.
6837 (mark_object): Use it. Adjust marking of misc objects
6838 and related comments.
6840 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
6842 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
6843 wrapper that is not needed because the wrapped code is a no-op (zero
6844 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
6845 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
6847 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
6849 * alloc.c (mark_buffer): Simplify. Remove prototype.
6850 (mark_object): Add comment. Reorganize marking of vector-like
6851 objects. Use CHECK_LIVE for all vector-like objects except buffers
6852 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
6853 Avoid redundant calls to mark_vectorlike for bool vectors.
6855 2012-06-30 Glenn Morris <rgm@gnu.org>
6857 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
6859 * epaths.in (PATH_SITELOADSEARCH): New.
6860 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
6861 This is rather than relying on --enable-locallisppath elements
6862 having "site-lisp" in their names. (Bug#10208#25, 11658)
6864 2012-06-30 Eli Zaretskii <eliz@gnu.org>
6866 * w32proc.c (sys_select): Accept and ignore one more argument.
6868 * w32.c (emacs_gnutls_pull): Call select with one more argument.
6870 * sysselect.h [DOS_NT]: Don't include sys/select.h.
6871 (pselect) [!MS_DOS]: Redirect to sys_select.
6873 * sysdep.c: Don't include dos.h and dosfns.h.
6875 * process.c (sys_select):
6876 * msdos.c (sys_select): Accept one more argument and ignore it.
6878 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
6879 adapt data types and code to that.
6882 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
6883 which clashes with the gnulib function of the same name.
6885 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
6887 * font.c (font_style_to_value, font_style_symbolic)
6888 (font_prop_validate_style): Add type checks for values in
6891 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
6893 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
6896 2012-06-29 Eli Zaretskii <eliz@gnu.org>
6898 * xdisp.c (try_window_id): Undo last change.
6900 * w32.c (getwd): Adjust commentary about startup_dir.
6901 (init_environment): Always call sys_access, even in non-MSVC
6902 builds. Don't chdir to the directory of the Emacs executable.
6903 This undoes code from 1997 which was justified by the need to
6904 "avoid conflicts when removing and renaming directories". But its
6905 downside was that every relative file name was being interpreted
6906 relative to the directory of the Emacs executable, which can never
6907 be TRT. In particular, it broke sys_access when called with
6908 relative file names.
6909 (sys_access): Map GetLastError to errno.
6911 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6913 * window.h (struct window): Change type of 'fringes_outside_margins'

6929 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6931 * editfns.c (region_limit): Fix type mismatch.
6933 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
6935 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
6936 undefined. Convert from xassert to eassert.
6937 * nsmenu.m: Convert from xassert to eassert.

6953 * window.h (struct window): Change type of 'hscroll',
6954 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
6955 'last_modified' and 'last_overlay_modified' to EMACS_INT.
6956 Adjust users accordingly.
6957 * xdisp.c (try_cursor_movement): Replace type check with eassert.
6958 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
6959 from EMACS_INT to ptrdiff_t.

7035 * alloc.c (allocate_string): Omit intervals initialization.
7036 * alloc.c (make_uninit_multibyte_string): Initialize intervals

7095 a better opportunity to optimize away calls to strlen when the

7097 * image.c (imagemagick_error): Convert to build_string.
7098 * w32proc.c (sys_spawnve): Likewise.

7101 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
7103 Use sprintf return value instead of invoking strlen on result.
7104 In the old days this wasn't portable, since some sprintf
7105 implementations returned char *. But they died out years ago and
7106 Emacs already assumes sprintf returns int.
7107 Similarly for float_to_string.
7108 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

7115 * xfns.c (syms_of_xfns):
7116 Use sprintf or float_to_string result to avoid need to call strlen.
7117 * data.c (Fnumber_to_string):
7118 Use make_unibyte_string, since the string must be ASCII.
7119 * lisp.h, print.c (float_to_string): Now returns int length.
7120 * term.c (produce_glyphless_glyph):
7121 Use sprintf result rather than recomputing it.
7123 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

7156 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

7159 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7161 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7162 instead of truncating it to 63 (admittedly a generous limit).
7164 * process.c: Fix spelling and caps in comments.
7166 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
7168 * emacs.c (setpgrp): Remove definition, unused.

7222 * keyboard.c (kbd_buffer_get_event):

7245 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
7246 Privately reported by Herbert J. Skuhra.
7247 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
7249 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

7284 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
7285 Privately reported by Herbert J. Skuhra.
7286 [__FreeBSD__]: Remove "*/" typo after "#include".
7287 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
7288 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
7289 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
7290 Don't assume EMACS_TIME and struct timeval are the same type.
7292 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7294 Support higher-resolution time stamps (Bug#9000).
7295 The time stamps are only nanosecond-resolution at the C level,
7296 since that's the best that any real-world system supports now.
7297 But they are picosecond-resolution at the Lisp level, as that's
7298 easy, and leaves room for future OS improvements.
7300 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7303 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7304 Don't get current time unless it's needed.
7306 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7307 now provides it if it's absent.
7308 (start_atimer): Port to higher-res time stamps.
7309 Check for time stamp overflow. Don't get current time more
7310 often than is needed.
7312 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7313 Include systime.h, not time.h.
7314 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

7320 (struct image): Timestamp now has higher resolution.
7322 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7323 has at least microseconds now. All uses removed.
7324 (update_frame, update_single_window, update_window, update_frame_1)
7325 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7326 (duration_to_sec_usec): Remove; no longer needed.

7336 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7337 Report an error if the time is invalid, rather than having the caller
7340 * fileio.c: Include <stat-time.h>
7341 (Fcopy_file): Copy higher-resolution time stamps.
7342 Prefer to set the time stamp via a file descriptor if that works.

7345 (Fvisited_file_modtime, Fset_visited_file_modtime):
7346 Support higher-resolution time stamps.
7348 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7350 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7352 * image.c (prepare_image_for_display, clear_image_cache)
7353 (lookup_image): Port to higer-resolution time stamps.
7355 * keyboard.c (start_polling, bind_polling_period):
7356 Check for time stamp overflow.

7358 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7359 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7360 Port to higher-resolution time stamps. Do not assume time_t is signed.
7361 (decode_timer): New function. Timers are now vectors of length 9,
7362 not 8, to accommodate the picosecond component.
7363 (timer_check_2): Use it.
7365 * nsterm.m (select_timeout, timeval_subtract): Remove.
7366 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7367 as they're a bit more accurate and handle overflow better.
7368 (ns_select): Change prototype to be compatible with pselect.
7369 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7370 * nsterm.h (ns_select): Adjust prototype.
7372 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7373 us-resolution time stamps.
7374 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7376 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7378 * lisp.h (time_overflow): New decl.
7379 (wait_reading_process_output): First arg is now intmax_t, not int,
7380 to accommodate larger waits.
7382 * process.h (struct Lisp_Process.read_output_delay):
7383 Now counts nanoseconds, not microseconds.
7384 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

7389 (Faccept_process_output, wait_reading_process_output):
7390 Check for time stamp overflow. Do not assume time_t is signed.
7391 (select_wrapper): Remove; we now use pselect.
7392 (Fprocess_attributes): Now generates ns-resolution time stamps.
7394 * sysdep.c: Include utimens.h. Don't include utime.h
7395 or worry about struct utimbuf; gnulib does that for us now.
7396 (gettimeofday): Remove; gnulib provides a substitute.
7397 (make_timeval): New function.
7398 (set_file_times): Now sets ns-resolution time stamps.
7399 New arg FD; all uses changed.
7400 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7401 (system_process_attributes):
7402 Now returns ns-resolution time stamp. All uses changed.
7403 Check for time stamp overflow.
7405 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7406 provides a substitute now.
7408 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7409 since it guarantees struct timespec.
7410 (EMACS_TIME): Now struct timespec, so that we can support
7411 ns-resolution time stamps.
7412 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7413 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7414 (EMACS_USECS): Remove.
7415 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7416 so multiply the arg by 1000 before storing it.
7417 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7419 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7420 Port to ns-resolution time stamps.
7421 (EMACS_TIME_NEG_P): Remove; replaced by....

7426 (make_timeval, make_lisp_time, decode_time_components): New decls.
7427 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7428 that it mishandled time_t overflow. You can't compare by subtracting!
7429 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7430 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

7441 (w32_get_internal_run_time):
7442 Port to higher-resolution Emacs time stamps.

7448 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7449 for compatibility with pselect. Support ns-resolution time stamps.
7451 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7453 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7454 Check for time stamp overflow, and support ns-resolution time stamps.
7456 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7457 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7458 (timeval_subtract): Remove; no longer needed.
7459 (XTflash, XTring_bell, x_wait_for_event):
7460 Port to ns-resolution time stamps. Don't assume time_t is signed.

7466 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7468 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7469 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7470 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
7471 staticidx goes up to 1597 out of 1600 = 0x640.)
7473 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
7475 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
7476 Otherwise, the umask might be mistakenly 0 while handling input signals.

7510 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
7511 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
7512 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

7521 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7522 gets killed during executing of this function (Bug#11665).
7523 Try to always return Qt when the buffer has been actually killed.
7524 (Vkill_buffer_query_functions): In doc-string say that functions
7525 run by this hook should not change the current buffer.
7527 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
7529 Fix recently-introduced process.c problems found by static checking.

7550 This removes the need for CHECK.
7551 (CHECK): Remove. Its comments about always evaluating its
7552 argument were confusing, as 'eassert' typically does not evaluate
7555 * coding.c (produce_chars): Use ptrdiff_t, not int.
7557 * xterm.c (x_draw_underwave): Check for integer overflow.
7558 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

7732 * alloc.c (make_number) [!defined make_number]:
7733 Remove, as lisp.h always defines this now.
7734 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
7735 (roundup_size): Verify that it is a power of 2.
7736 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
7737 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
7738 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
7739 -DUSE_LSB_TAG=0, to override the automatically-selected default.
7740 USE_LSB_TAG now is always defined to be either 0 or 1.
7742 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
7743 code works fine either way, and efficiency is not a concern here,
7744 as the union type is for debugging, not for production.
7745 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
7746 Use an inline function on all platforms when using the union type,
7747 since this is simpler and 'static inline' can be used portably
7749 (LISP_INITIALLY_ZERO): New macro.
7750 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
7751 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
7753 2012-06-12 Glenn Morris <rgm@gnu.org>

7768 MagickMergeImageLayers is undefined. Use pixel pusher loop if
7769 MagickExportImagePixels is undefined.

7777 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/darwin.h:
7778 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
7779 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
7780 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
7782 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
7784 * alloc.c (make_byte_code): New function.

7817 2012-06-09 Michael Albinus <michael.albinus@gmx.de>
7819 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
7820 dbus_type_is_basic if available.
7821 (xd_extract_signed, xd_extract_unsigned): Rename from
7822 extract_signed and extract_unsigned, respectively. Adapt callers.
7824 2012-06-09 Chong Yidong <cyd@gnu.org>
7826 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).

7831 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
7833 * xdisp.c (vmessage): Treat frame message as multibyte.
7834 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
7835 would generate the diagnostic "Making \302\247 buffer-local while
7838 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7840 * dispnew.c (showing_window_margins_p): Undo last change, which

7851 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
7853 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
7854 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
7856 2012-06-08 Eli Zaretskii <eliz@gnu.org>
7858 * alloc.c (allocate_vectorlike): Fix last change.
7860 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
7862 Block-based vector allocation of small vectors.
7863 * lisp.h (struct vectorlike_header): New field `nbytes',
7864 adjust comment accordingly.
7865 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
7866 to denote vector blocks. Adjust users (live_vector_p,
7867 mark_maybe_pointer, valid_lisp_object_p) accordingly.
7868 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
7869 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
7870 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
7871 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
7872 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

7887 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
7889 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
7891 * doprnt.c (doprnt): Truncate multibyte char correctly.
7892 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
7893 would mishandle a string argument "Xc" if X was a multibyte
7894 character of length 2: it would truncate after X's first byte
7895 rather than including all of X.
7897 2012-06-06 Chong Yidong <cyd@gnu.org>
7899 * buffer.c (word_wrap): Doc fix.
7901 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

7946 * minibuf.c (Fassoc_string): Remove duplicate declaration.
7948 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
7949 Convert pctcpu and pctmem to Lisp float properly.
7950 Let the compiler fold better, as 100.0/0x8000 is exact.
7952 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
7954 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
7957 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
7959 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
7961 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
7963 For a 'struct window', replace some Lisp_Object fields to
7964 bitfields where appropriate, remove unused fields.
7965 * window.h (struct window): Remove unused 'last_mark_x' and
7966 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
7967 change its type from Lisp_Object to bitfield.
7968 Change type of 'force_start', 'optional_new_start',
7969 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
7970 fields from Lisp_Object to bitfield. Adjust users accordingly.
7972 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
7974 Pacify gcc -Wdouble-precision when using Xaw.
7975 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
7976 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
7977 Use 'float' consistently, rather than 'float' in most places
7978 and 'double' in a couple of places.
7980 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7982 * xdisp.c (handle_stop): Detect whether we have overlay strings
7983 loaded by testing it->current.overlay_string_index to be
7984 non-negative, instead of checking whether n_overlay_strings is
7985 positive. (Bug#11587)
7987 2012-05-31 Chong Yidong <cyd@gnu.org>
7989 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
7991 * doc.c (Fsubstitute_command_keys): Doc fix.
7993 2012-05-31 Eli Zaretskii <eliz@gnu.org>
7995 * search.c (search_buffer): Remove calls to
7996 r_alloc_inhibit_buffer_relocation, as it is now called by
7997 maybe_unify_char, which was the cause of relocation of buffer text
8000 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8002 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8003 for the duration of call to load_charset, to avoid problems with
8004 callers of maybe_unify_char that access buffer text through C
8007 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8008 decrement the inhibition flag, instead of just setting or
8011 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8013 Remove obsolete '#define static' cruft.
8014 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8015 This #undef was "temporary" in 2000; it is no longer needed
8016 now that '#define static' has gone away.
8017 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8018 (gray_bitmap_bits): Remove; no longer needed.
8019 All uses replaced with definiens.
8020 * xterm.c: Include "bitmaps/gray.xbm".
8022 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8024 Clean up __executable_start, monstartup when --enable-profiling.
8025 The following changes affect the code only when profiling.
8026 * dispnew.c (__executable_start): Rename from safe_bcopy.
8027 Define only on platforms that need it.
8028 * emacs.c: Include <sys/gmon.h> when profiling.
8029 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
8030 (__executable_start): Remove decl, since lisp.h does it now.
8031 (safe_bcopy): Remove decl; no longer has that name.
8032 (main): Coalesce #if into single bit of code, for simplicity.
8033 Cast pointers to uintptr_t, since standard libraries want integers

8057 * lisp.h (Qdefun): Remove.
8058 * lread.c (read1): Tiny simplification.
8060 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
8062 Do not create empty overlays with the evaporate property (Bug#9642).
8063 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8064 Bug#9642, but explicitly check that the buffer the overlay would
8065 be moved to is live and rearrange lines to make sure that errors
8066 will not put the overlay in an inconsistent state.
8067 (Fdelete_overlay): Cosmetics.
8069 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8071 * w32term.c (my_bring_window_to_top): New function.
8072 (x_raise_frame): Use handle returned by DeferWindowPos, which
8073 could be different from the original one.
8074 Call my_bring_window_to_top instead of my_set_foreground_window.
8077 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
8078 by calling BringWindowToTop.

8083 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
8085 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
8086 This avoids undefined behavior that might cause the eassert
8087 to not catch an out-of-range value.
8089 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8091 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

8103 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
8105 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8106 Only r_alloc_inhibit_buffer_relocation needed to be added;
8107 the others were already declared.
8109 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8110 before checking whether it's out of range. Put the check inside
8112 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8114 2012-05-27 Ken Brown <kbrown@cornell.edu>
8116 * callproc.c (Fcall_process): Restore a line that was accidentally
8117 commented out in the 2011-02-13 change (bug#11547).

8121 * lisp.h [REL_ALLOC]: Add prototypes for external functions
8122 defined on ralloc.c.
8124 * buffer.c [REL_ALLOC]: Remove prototypes of
8125 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
8126 they are now on lisp.h.
8128 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8130 * search.c (search_buffer): Use it to inhibit relocation of buffer
8131 text while re_search_2 is doing its job, because re_search_2 is
8132 passed C pointers to buffer text. (Bug#11519)
8134 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8137 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8138 state after an additional call to move_it_in_display_line_to, keep
8139 the values of it->max_ascent and it->max_descent found for the
8141 (pos_visible_p): Revert the comparison against bottom_y to what it
8142 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8145 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8147 Fix coding-related core dumps with gcc -ftrapv.
8148 The code was computing A - B, where A and B are pointers, and B is
8149 random garbage. This can lead to core dumps on platforms that
8150 have special pointer registers, and it also leads to core dumps on
8151 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8152 A - B only when B is initialized properly.
8153 * coding.c (coding_set_source, coding_set_destination): Return void.
8154 (coding_change_source, coding_change_destinations): New functions,
8155 with the old behaviors of coding_set_source and coding_set_destination.
8156 All callers that need an offset changed to use these new functions.
8158 2012-05-26 Glenn Morris <rgm@gnu.org>
8160 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
8162 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8164 Extend mouse support on W32 text-mode console.
8165 * xdisp.c (draw_row_with_mouse_face):
8166 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8168 * w32console.c: Include window.h.
8169 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8171 (initialize_w32_display): Initialize mouse-highlight data.
8173 * w32inevt.c: Include termchar.h and window.h.
8174 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8175 moves, call note_mouse_highlight. If help_echo changed, call
8176 gen_help_event to produce help-echo message in the echo area.
8177 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8180 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8182 * lread.c (read1): Simplify slightly to avoid an overflow warning
8183 with GCC 4.7.0 on x86-64.
8185 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8187 * bidi.c (bidi_mirror_char): Revert last change: an int is
8188 definitely wide enough here.
8190 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
8192 Fix integer width and related bugs (Bug#9874).
8193 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):

8197 (make_unibyte_string, make_multibyte_string)
8198 (make_string_from_bytes, make_specified_string)
8199 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
8200 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
8202 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8203 (allocate_pseudovector):
8204 Use int, not EMACS_INT, where int is wide enough.
8205 (inhibit_garbage_collection, Fgarbage_collect):

8225 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8226 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8227 (validate_region): Omit unnecessary test for b <= e,
8228 since that's guaranteed by the previous test.

8230 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8231 (report_overlay_modification):

8237 * buffer.h: Adjust decls to match defn changes elsewhere.

8242 not int, to avoid needless 32-bit limit on 64-bit hosts.
8243 (exec_byte_code): Use tighter memory-full test, one that checks
8244 for alloca overflow. Don't compute the address of the object just
8245 before an array, as that's not portable. Use EMACS_INT, not
8246 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8247 * callint.c (Fcall_interactively):
8248 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

8261 (casify_object): Avoid integer overflow when overallocating buffer.
8262 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

8265 * category.h (CATEGORYP): Don't assume arg is nonnegative.

8269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8270 For CCL_MapSingle, check that content and value are in int range.

8272 Check that Vcode_version_map_vector is a vector.
8273 (resolve_symbol_ccl_program): Check that vector header is in range.
8274 Always copy the vector, so that we can check its contents reliably
8275 now rather than having to recheck each instruction as it's being
8276 executed. Check that vector words fit in 'int'.
8277 (ccl_get_compiled_code, Fregister_ccl_program)
8278 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8279 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

8281 contents are in range.
8282 (Fccl_execute_on_string): Check that status is in range.
8283 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8284 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8285 Accept and return EMACS_INT, not int, because callers can pass values

8294 avoid mishandling large integers.

8306 Don't assume unsigned int fits into fixnum, or that fixnum fits
8307 into unsigned int. Don't require max_code to be a valid fixnum;
8308 that's not true for gb10830 4-byte on a 32-bit host. Allow
8309 invalid_code to be a cons, for the same reason. Require code_offset
8310 to be a character. Avoid int overflow if max_char is close
8312 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8313 this is intended anyway and avoids some undefined behavior.
8314 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8315 INDEX_TO_CODE_POINT, as that's what it expects.
8316 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8317 * charset.h (DECODE_CHAR): Return int, not unsigned;
8318 this is what was intended anyway, and it avoids undefined behavior.
8319 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8320 integer-overflow issues.
8321 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8322 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8323 where the argument is EMACS_INT, and this behavior is not intended.
8324 * chartab.c (Fmake_char_table, Fset_char_table_range)
8325 (uniprop_get_decoder, uniprop_get_encoder):
8326 Don't assume fixnum fits in int.
8327 * cmds.c (move_point): New function, that does the gist of
8328 Fforward_char and Fbackward_char, but does so while checking
8329 for integer overflow more accurately.
8330 (Fforward_char, Fbackward_char): Use it.
8331 (Fforward_line, Fend_of_line, internal_self_insert)
8332 (internal_self_insert):

8988 (struct scroll_bar): Use struct vectorlike_header
8989 rather than rolling our own approximation.
8990 (SCROLL_BAR_VEC_SIZE): Remove; not used.
8992 2012-05-25 Glenn Morris <rgm@gnu.org>
8994 * lisp.mk (lisp): Update for more files being compiled now.
8996 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
8998 * lread.c: Remove `read_pure' which makes no difference.
8999 (read_pure): Remove var.
9000 (unreadpure): Remove function.
9001 (readevalloop): Don't call read_list with -1 flag.

9016 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
9019 This directory predates autoconf and is no longer needed nowadays.
9020 Move its few remaining bits of functionality to where they're needed.
9021 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

9030 (EMACS_UINT): Define unconditionally now.
9031 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
9032 (BITS_PER_EMACS_INT): New constants, replacing
9033 what used to be in config.h, but not useful in #if.
9034 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
9035 define them any more.
9036 (VAL_MAX): New macro.
9038 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
9039 BITS_PER_EMACS_INT, in #if.
9040 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
9041 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
9042 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
9043 * s/ms-w32.h (DATA_START):
9044 Move here from removed file m/intel386.h.
9045 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
9046 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
9048 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
9050 Assume C89 or later.

9059 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
9060 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
9061 * xterm.c (input_signal_count): Assume volatile works.
9063 2012-05-21 Ken Brown <kbrown@cornell.edu>
9065 * xgselect.c (xg_select): Fix first argument in call to 'select'
9068 2012-05-20 Ken Brown <kbrown@cornell.edu>
9070 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
9071 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
9073 2012-05-19 Ken Brown <kbrown@cornell.edu>
9075 * xfns.c (x_in_use): Remove `static' qualifier.
9076 * xterm.h (x_in_use): Declare.
9077 * xgselect.c: Include xterm.h.
9078 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
9079 and `display_arg' (bug#9754).
9081 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
9083 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
9085 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
9086 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
9088 2012-05-18 Eli Zaretskii <eliz@gnu.org>
9090 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
9092 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
9093 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
9095 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
9096 reference to image_cache->refcount.
9097 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
9099 2012-05-17 Juri Linkov <juri@jurta.org>
9101 * search.c (Fword_search_regexp, Fword_search_backward)
9102 (Fword_search_forward, Fword_search_backward_lax)
9103 (Fword_search_forward_lax): Move functions to isearch.el
9104 (bug#10145, bug#11381).
9106 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
9108 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
9110 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
9112 * lread.c (init_obarray): Declare Qt and Qnil as special.
9114 2012-05-14 Glenn Morris <rgm@gnu.org>
9116 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9117 Put "libexec" before "bin", for the sake of init_callproc_1.
9119 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9121 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
9123 * unexaix.c: Port to more-recent AIX compilers.
9124 (report_error, report_error_1, make_hdr, copy_sym)
9125 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9126 Make arguments const char *, not char *, to avoid violations of C
9127 standard and to fix some AIX warnings reported by Gilles Pion.
9129 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9131 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9132 already have overlays loaded.
9133 (handle_single_display_spec): Before returning without displaying
9134 fringe bitmap, synchronize the bidi iterator with the main display
9135 iterator, by calling iterate_out_of_display_property.
9136 (iterate_out_of_display_property): Detect buffer iteration by
9137 testing that it->string is a Lisp string.
9138 (get_next_display_element): When the current object is exhausted,
9139 and there's something on it->stack, call set_iterator_to_next to
9140 proceed with what's on the stack, instead of returning zero.
9141 (set_iterator_to_next): If called at the end of a Lisp string,
9142 proceed to consider_string_end without incrementing string
9143 position. Don't increment display vector index past the end of
9144 the display vector. (Bug#11417)
9145 (pos_visible_p): Don't report a position visible when move_it_to
9146 stopped at the last line of window, which happens to be scanned
9147 backwards by the bidi iteration. (Bug#11464)
9149 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9151 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9152 and right-margin display specs even if the spec is invalid or we
9153 are on a TTY, and thus unable to display on the fringes.
9154 That's because the text with the property will not be displayed anyway,
9155 so we need to signal to the caller that this is a "replacing"
9156 display spec. This fixes display when the spec is invalid or we
9159 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9161 * unexaix.c (make_hdr): Fix typo in prototype.
9162 This bug broke the build on AIX. Problem reported by Gilles Pion.
9164 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9166 * keyboard.c (kbd_buffer_get_event): Read special events also in
9167 batch mode. (Bug#11415)
9169 2012-05-12 Glenn Morris <rgm@gnu.org>
9171 * ns.mk: Update for ns_appbindir no longer having trailing "/".
9173 2012-05-12 Eli Zaretskii <eliz@gnu.org>
9175 * lisp.mk (lisp): Add newcomment.elc.
9177 2012-05-12 Glenn Morris <rgm@gnu.org>
9179 * Makefile.in (MKDIR_P): New, set by configure.
9180 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9182 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9184 Remove unused function hourglass_started.
9185 * dispextern.h (hourglass_started):
9186 * w32fns.c (hourglass_started):
9187 * xdisp.c (hourglass_started): Remove.
9189 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
9191 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
9192 Update dependencies.
9194 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9196 * xgselect.c (xg_select): Put maxfds+1 into a var.
9197 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9199 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9201 2012-05-10 Dave Abrahams <dave@boostpro.com>
9203 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9204 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9206 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9208 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9209 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9210 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9211 Initialize xd_registered_buses.
9213 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9215 Untag more efficiently if USE_LSB_TAG.
9216 This is based on a proposal by YAMAMOTO Mitsuharu in
9217 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9218 For an admittedly artificial (nth 8000 longlist) benchmark on
9219 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9220 Emacs's overall text size by 1%.
9221 * lisp.h (XUNTAG): New macro.
9222 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9223 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9224 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9225 * eval.c (Fautoload):
9226 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9227 * frame.h (XFRAME): Use XUNTAG.
9229 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9230 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9231 Remove unportable assumptions about print widths of types like
9233 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9234 intptr_t when converting between pointer and integer, to avoid GCC
9235 warnings about wrong width.
9237 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9239 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9240 stack for each reader_thread, instead of defaulting to 8MB
9241 determined by the linker. This avoids failures in creating
9242 subprocesses on Windows 7, see the discussion in this thread:
9243 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9245 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9247 Fix up display of the *Minibuf-0* buffer in the mini window.
9248 * keyboard.c (read_char): Don't clear the echo area if there's no
9250 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9251 contents of *Minibuf-0*) if there's no message displayed in its stead.
9253 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9255 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9258 2012-05-06 Chong Yidong <cyd@gnu.org>
9260 * lisp.mk (lisp): Update.
9262 2012-05-05 Jim Meyering <meyering@redhat.com>
9264 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9266 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9268 * data.c (PUT_ERROR): New macro.
9269 (syms_of_data): Use it. Add new error type `user-error'.
9270 * undo.c (user_error): New function.
9271 (Fprimitive_undo): Use it.
9272 * print.c (print_error_message): Adjust print style for `user-error'.
9273 * keyboard.c (user_error): New function.
9274 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9276 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9278 Do not limit current-time-string to years 1000..9999.
9279 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9280 (Fcurrent_time_string): Support any year that is supported by the
9281 underlying localtime representation. Don't use asctime, as it
9282 has undefined behavior for years outside the range -999..9999.
9284 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9286 Fix race conditions involving setenv, gmtime, localtime, asctime.
9287 Without this fix, interrupts could mess up code that uses these
9288 nonreentrant functions, since setting TZ invalidates existing
9289 tm_zone or tzname values, and since most of these functions return
9290 pointers to static storage.
9291 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9292 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9293 Grow the critical sections to include not just invoking
9294 localtime/gmtime, but also accessing these functions' results
9295 including their tm_zone values if any, and any related TZ setting.
9296 (format_time_string): Last arg is now struct tm *, not struct tm **,
9297 so that the struct tm is saved in the critical section.
9298 All callers changed. Simplify allocation of initial buffer, partly
9299 motivated by the fact that memory allocation needs to be outside
9300 the critical section.
9302 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9304 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9305 with RESET_INTERVAL.
9307 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9308 Remove duplicated buffer name initialization.
9310 2012-05-02 Jim Meyering <jim@meyering.net>
9312 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9314 * xfns.c (x_window): Use xstrdup (Bug#11375).
9316 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9318 * xdisp.c (pos_visible_p): If already at a newline from the
9319 display string before the 'while' loop, don't walk back the glyphs
9320 from it3.glyph_row. Solves assertion violation when the display
9321 string begins with a newline (egg.el). (Bug#11367)
9323 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9325 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9328 2012-05-01 Glenn Morris <rgm@gnu.org>
9330 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9331 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9332 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9333 All were removed before 23.1.
9335 * dispnew.c: Remove HAVE_LIBNCURSES test;
9336 it is always true on relevant platforms.
9338 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9339 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9341 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

9351 Do not avoid creating empty evaporating overlays (Bug#9642).
9352 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9353 That is, do not delete an evaporating overlay if it becomes
9354 empty after its bounds are adjusted to fit within its buffer.
9355 This fix caused other problems, and I'm reverting it until we get
9356 to the bottom of them.
9358 2012-04-27 Chong Yidong <cyd@gnu.org>
9360 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9362 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9364 * xdisp.c (pos_visible_p): If the window start position is beyond
9365 ZV, start the display from buffer beginning. Prevents assertion
9366 violation in init_iterator when the minibuffer window is scrolled
9369 * window.c (window_scroll_pixel_based): Likewise.
9371 2012-04-27 Chong Yidong <cyd@gnu.org>

9388 display element, check also the underlying string or buffer
9389 character. (Bug#11341)
9391 * w32menu.c: Include w32heap.h.
9392 (add_menu_item): If the call to AppendMenuW (via
9393 unicode_append_menu) fails, disable Unicode menus only if we are
9394 running on Windows 9X/Me.
9396 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9398 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

9409 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9410 manipulation of :loaded-from data.
9412 2012-04-23 Juanma Barranquero <lekktu@gmail.com>

9415 now a cons (bug#11311).
9417 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9419 Do not create empty overlays with the evaporate property (Bug#9642).
9420 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9421 if it becomes empty after its bounds are adjusted to fit within
9422 its buffer. Without this fix, in a nonempty buffer (let ((o
9423 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9424 yields an empty overlay that has the evaporate property, which is
9425 not supposed to happen.
9427 Fix minor GTK3 problems found by static checking.
9428 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

9448 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9449 (__malloc_size_t, __malloc_ptrdiff_t):

9529 since the two debugging options are incompatible.
9530 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
9532 (mem_init, mem_insert, mem_insert_fixup):
9533 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

9542 * sysdep.c [__FreeBSD__]: Minor cleanups.
9543 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9544 Use Emacs indenting style more consistently. Avoid some casts.
9545 Use 'double' consistently rather than mixing 'float' and 'double'.
9547 2012-04-21 Eduard Wiebe <usenet@pusto.de>
9549 * sysdep.c (list_system_processes, system_process_attributes):
9550 Add implementation for FreeBSD (Bug#5243).

9565 (print_object): Check for cycles even when print-circle is nil and
9566 print-gensym is t, but only check print_depth if print-circle is nil.
9568 2012-04-20 Chong Yidong <cyd@gnu.org>
9570 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9571 set the status to "failed" and ensure that sentinel is run.

9626 New extern decls, to avoid calling undeclared functions.
9627 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9628 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9629 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
9630 (NEED_MEM_INSERT): New macro.
9631 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9632 Remove one incorrect comment and fix another.

9646 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9647 Remove decls. This fixes an "It stinks!".
9649 * alloc.c (which_symbols): Fix alignment issue / type clash.
9651 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9653 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9674 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9676 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
9678 * lread.c (lisp_file_lexically_bound_p):

9699 2012-04-11 Daniel Colascione <dancol@dancol.org>
9701 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9702 against is gone. It's better to use vfork now so that when Cygwin
9703 gains a new, working vfork, we use it automatically (bug#10398).
9705 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

9726 being loaded (bug#10424).
9728 2012-04-09 Glenn Morris <rgm@gnu.org>
9730 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

9743 Add convenience `GNUTLS_LOG2i' macro.
9745 * gnutls.c (gnutls_log_function2i): Convenience log function.
9746 (emacs_gnutls_read): Use new log functions,
9747 `gnutls_handshakes_tried' process member, and
9748 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
9749 attempts per process (connection).

9760 2012-04-09 Eli Zaretskii <eliz@gnu.org>
9762 * xdisp.c (set_cursor_from_row): If the display string appears in
9763 the buffer at position that is closer to point than the position
9764 after the display string, display the cursor on the first glyph of
9765 the display string. Fixes cursor display when a 'display' text
9766 property immediately follows invisible text. (Bug#11094)
9768 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
9770 composite.c: use 'double' consistently
9771 * composite.c (get_composition_id): Use 'double' consistently
9772 instead of converting 'float' to 'double' and vice versa; this is
9773 easier to understand and avoids a GCC warning.
9775 2012-04-09 Glenn Morris <rgm@gnu.org>
9777 * Makefile.in: Generate leim-list with bootstrap-emacs, in
9778 preparation for dumping it with emacs. (Bug#4789)

9800 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
9801 (mark_memory): Mark Lisp_Objects only if pointers might hide in
9802 objects, as mark_maybe_pointer will catch them otherwise.
9803 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
9804 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

9822 [!WINDOWSNT]: New macros.
9823 (init_libxml2_functions, libxml2_loaded_p): New functions.
9824 (parse_region): Call fn_xmlCheckVersion instead of using the macro

9827 Calls xmlCleanupParser only if libxml2 was loaded (or statically
9829 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
9830 Call init_libxml2_functions before calling libxml2 functions.
9831 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
9833 * emacs.c: Don't include libxml/parser.h.
9834 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
9835 xmlCleanupParser directly.

9847 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
9848 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
9849 about subtle differences between FETCH_CHAR* and STRING_CHAR*
9850 macros related to unification of CJK characters. For the details,
9851 see the discussion following the message here:
9852 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
9854 2012-04-04 Chong Yidong <cyd@gnu.org>
9856 * keyboard.c (Vdelayed_warnings_list): Doc fix.
9858 2012-04-01 Eli Zaretskii <eliz@gnu.org>
9860 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

9868 2012-03-31 Eli Zaretskii <eliz@gnu.org>
9870 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
9871 position we get to after a call to move_it_to fails the
9872 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
9873 only if we wind up in a string from display property. (Bug#11063)
9875 * window.c (Fdelete_other_windows_internal): Invalidate the row
9876 and column information about mouse highlight, so that redisplay
9877 restores it after reallocating the glyph matrices. (Bug#7464)
9879 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
9880 string comes from a `display' text property, use the buffer
9881 position of that property as if we actually saw that position in
9883 (move_it_by_lines): Remove the assertion that
9884 "it->current_x == 0 && it->hpos == 0" which can be legitimately
9885 violated when there's a before-string at the beginning of a line.
9888 2012-03-30 Eli Zaretskii <eliz@gnu.org>
9890 * xdisp.c (append_space_for_newline): If the default face was
9891 remapped, use the remapped face for the appended newline.
9892 (extend_face_to_end_of_line): Use the remapped default face for
9893 extending the face to the end of the line.
9894 (display_line): Call extend_face_to_end_of_line when the default
9895 face was remapped. (Bug#11068)
9897 2012-03-29 Eli Zaretskii <eliz@gnu.org>
9899 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

9913 bit length of glyphless.ch to 25 (Bug#11082).
9915 2012-03-26 Chong Yidong <cyd@gnu.org>
9917 * keyboard.c (Vselection_inhibit_update_commands): New variable.
9918 (command_loop_1): Use it; inhibit selection update for
9919 handle-select-window too (Bug#8996).
9921 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
9923 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
9925 2012-03-25 Kenichi Handa <handa@m17n.org>
9927 * dispextern.h (struct glyph): Change the bit length of
9928 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
9930 2012-03-24 Eli Zaretskii <eliz@gnu.org>
9932 * s/ms-w32.h (tzname): Include time.h before redirecting to
9933 _tzname. Fixes the MSVC build. (Bug#9960)
9935 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
9937 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
9940 * xterm.c (XTread_socket): Only modify handling_signal if
9941 !SYNC_INPUT. (Bug#11080)
9943 2012-03-23 Eli Zaretskii <eliz@gnu.org>
9945 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
9946 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
9947 when fetching a multibyte character consumes more bytes than
9948 CHAR_BYTES returns, due to unification of CJK characters in
9949 string_char. (Bug#11073)
9951 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
9953 * process.c (wait_reading_process_output): Handle pty disconnect
9954 by refraining from sending oneself a SIGCHLD (bug#10933).

9977 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
9978 to reflect default non-nil value of redisplay-dont-pause.
9980 2012-03-19 Kenichi Handa <handa@m17n.org>
9982 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
9983 it fit in a valid range (Bug#11003).
9985 2012-03-18 Eli Zaretskii <eliz@gnu.org>
9987 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
9988 that is not from display property, accept the row as a "cursor
9989 row" if one of the string's character has a non-nil `cursor'
9990 property. Fixes cursor positioning when there are newlines in
9991 overlay strings, e.g. in icomplete.el. (Bug#11035)
9993 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
9995 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).

9999 * eval.c (inhibit_lisp_code): Rename from
10000 inhibit_window_configuration_change_hook; move from window.c.
10002 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10003 * window.c (run_window_configuration_change_hook)
10004 (syms_of_window): Callers changed.

10024 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10027 2012-03-03 Glenn Morris <rgm@gnu.org>
10029 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10031 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10033 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10034 position past the first glyph_row that ends at ZV. (Bug#10902)
10035 (redisplay_window, next_element_from_string): Fix typos in
10037 (redisplay_window): Pass to move_it_vertically the margin in
10038 pixels, not in screen lines.
10040 2012-03-02 Glenn Morris <rgm@gnu.org>
10042 * buffer.c (buffer-list-update-hook): Doc fix.
10044 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10046 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10047 push_it before setting up the iterator for the first overlay
10048 string, even if we have an empty string loaded.
10049 (next_overlay_string): If there's an empty string on the iterator
10050 stack, pop the stack. (Bug#10903)
10052 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10054 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10055 Suggested by Stefan Monnier in
10056 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10057 * alloc.c (widen_to_Lisp_Object): New static function.
10058 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10059 and widening them to Lisp_Objects. This would work even if
10060 USE_LSB_TAG is defined and wide integers are used, which might
10061 happen in a future version of Emacs.
10063 2012-02-25 Chong Yidong <cyd@gnu.org>
10065 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10068 * xselect.c (Fx_selection_exists_p): Doc fix.
10069 (x_clipboard_manager_save_all): Print an informative message
10070 before saving to clipboard manager.
10072 2012-02-24 Chong Yidong <cyd@gnu.org>
10074 * keyboard.c (process_special_events): Handle all X selection
10075 requests in kbd_buffer, not just the next one (Bug#8869).
10077 2012-02-23 Chong Yidong <cyd@gnu.org>
10079 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10080 call when setting menu-bar-lines and tool-bar-lines parameters.
10081 (unwind_create_frame_1): New helper function.

10102 when computing $valmask.
10104 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10105 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10106 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10107 It's useless in that case, and it can cause problems on hosts
10108 that allocate halves of EMACS_INT values separately.
10109 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10110 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10111 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10112 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10113 it avoids undefined behavior on hosts where shifting right by more
10114 than the word width has undefined behavior.
10116 2012-02-19 Chong Yidong <cyd@gnu.org>
10118 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10119 (Funhandled_file_name_directory, Ffile_name_as_directory)

10136 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
10138 2012-02-15 Chong Yidong <cyd@gnu.org>
10140 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

10156 2012-02-12 Chong Yidong <cyd@gnu.org>
10158 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10159 as that creates a dangerous corner case.
10161 * window.c (Fdelete_window_internal): Invalidate the mouse
10162 highlight (Bug#9904).
10164 2012-02-12 Glenn Morris <rgm@gnu.org>

10167 (Fx_get_selection_internal, Fx_disown_selection_internal)
10168 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
10169 * nsselect.m (Fx_own_selection_internal)
10170 (Fx_disown_selection_internal, Fx_selection_exists_p)
10171 (Fx_selection_owner_p, Fx_get_selection_internal):
10172 Sync docs and argument specs with the xselect.c versions.
10174 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
10176 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

10194 2012-02-07 Chong Yidong <cyd@gnu.org>
10196 * buffer.c (Fbuffer_local_variables)
10197 (buffer_lisp_local_variables): Handle unbound vars correctly;
10198 don't let Qunbound leak into Lisp.
10200 2012-02-07 Glenn Morris <rgm@gnu.org>
10202 * image.c (Fimagemagick_types): Doc fix.
10204 * image.c (imagemagick-render-type): Change it from a lisp object
10205 to an integer. Move the doc here from the lisp manual.

10234 * keyboard.c (adjust_point_for_property): Don't position point
10235 before BEGV. (Bug#10696)
10237 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
10239 Handle overflow when computing char display width (Bug#9496).
10240 * character.c (char_width): Return EMACS_INT, not int.
10241 (char_width, c_string_width): Check for overflow when
10242 computing the width; this is possible now that individual
10243 characters can have unbounded width. Problem introduced
10244 by merge from Emacs 23 on 2012-01-19.
10246 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

10779 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
10780 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
10781 this macro definition.
10783 * s/ms-w32.h (tzname): Redirect to _tzname for all values of

10808 * xdisp.c (redisplay_window): If cursor row is not fully visible
10809 after recentering, and scroll-conservatively is set to a large
10810 number, scroll window by a few more lines to make the cursor fully
10811 visible and out of scroll-margin. (Bug#10105)
10812 (start_display): Don't move to the next line if the display should
10813 start at a newline that is part of a display vector or an overlay
10814 string. (Bug#10119)

10894 Otherwise, valgrind does not work on some platforms.
10895 Problem reported by Andreas Schwab in
10896 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
10897 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
10898 is set, removing the need for VIRT_ADDRESS_VARIES.
10899 (PURE_P): Use a more-efficient implementation that needs just one
10900 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
10901 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
10902 to 4 (xorl, subq, cmpq, setbe).
10903 * alloc.c (pure): Always extern now, since that's the
10904 VIRT_ADDR_VARIES behavior.
10905 (PURE_POINTER_P): Use a single comparison, not two, for
10906 consistency with the new puresize.h.
10907 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
10908 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

10914 (erase_phys_cursor, update_window_cursor, show_mouse_face)
10915 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
10916 behave as if the cursor position were at the window margin.
10918 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
10919 and the cursor position is out of bounds, behave as if the cursor
10920 position were at the window margin. (Bug#10075)
10922 2011-11-18 Chong Yidong <cyd@gnu.org>
10924 * window.c (Fwindow_combination_limit): Make first argument
10925 non-optional, since it is meaningless for live windows like the

10943 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
10945 * xdisp.c (row_hash): New function, body extracted from
10946 compute_line_metrics.
10947 (compute_line_metrics): Call row_hash, instead of computing the
10950 * dispnew.c (verify_row_hash): Call row_hash for computing the
10951 hash code of a row, instead of duplicating code from xdisp.c.
10953 * dispextern.h (row_hash): Add prototype.
10955 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
10957 * frame.c (delete_frame): Don't delete the terminal when the last

10982 (recombine_windows, make_parent_window, make_window)
10983 (Fsplit_window_internal, saved_window)
10984 (Fset_window_configuration, save_window_save): Rename all
10985 occurrences of window_nest to window_combination_limit.

10991 2011-11-14 Eli Zaretskii <eliz@gnu.org>
10993 * xdisp.c (display_line): Move the call to
10994 highlight_trailing_whitespace before the call to
10995 compute_line_metrics, since the latter needs to see the final
10996 faces of all the glyphs to compute ROW's hash value.
10997 Fixes assertion violations in row_equal_p. (Bug#10035)
10999 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
11001 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
11002 just return (bug#10044).
11004 2011-11-12 Eli Zaretskii <eliz@gnu.org>
11006 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11007 with user-defined heap size. Bump the default size of the temacs

11009 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
11011 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11012 current_matrix and desired_matrix. (Bug#9990)
11013 (verify_row_hash) [XASSERTS]: New function.

11047 avoid a crash (bug#9496).
11049 2011-11-09 Chong Yidong <cyd@gnu.org>
11051 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

11058 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
11060 Avoid some portability problems by eschewing 'extern inline' functions.
11061 The trivial performance wins aren't worth the portability hassles; see
11062 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11064 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11065 (window_box_width, window_box_left, window_box_left_offset)
11066 (window_box_right, window_box_right_offset): Undo previous change,
11067 by removing the "extern"s.
11068 * intervals.c (adjust_intervals_for_insertion)
11069 (adjust_intervals_for_deletion): Undo previous change,
11070 making these static again.
11071 (offset_intervals, temp_set_point_both, temp_set_point)
11072 (copy_intervals_to_string): No longer inline.
11073 * xdisp.c (window_text_bottom_y, window_box_width)

11113 This is also needed for porting to any host where GC_MARK_STACK is
11114 not GC_MAKE_GCPROS_NOOPS.
11115 (which_symbols): Use it.
11117 2011-11-07 Kenichi Handa <handa@m17n.org>

11130 * xmenu.c (cleanup_widget_value_tree): New function.
11131 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
11132 calling free_menubar_widget_value_tree directly (Bug#9830).
11134 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
11136 Fix some portability problems with 'inline'.

11138 (window_box_width, window_box_left, window_box_left_offset)
11139 (window_box_right, window_box_right_offset): Declare extern.
11140 Otherwise, these inline functions do not conform to C99 and
11141 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11142 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11143 * intervals.c (adjust_intervals_for_insertion)
11144 (adjust_intervals_for_deletion): Now extern, because otherwise the
11145 extern inline functions 'offset_intervals' couldn't refer to it.
11146 (static_offset_intervals): Remove.
11147 (offset_intervals): Rewrite using the old contents of
11148 static_offset_intervals. The old version didn't conform to C99
11149 because an extern inline function contained a reference to an
11150 identifier with static linkage.

11202 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
11203 (unwind_create_frame): New function (Bug#9943).

11216 official. Move initialization of image_cache_refcount and
11217 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

11257 previous/next-single-property-change returns nil, treat that as
11258 the beginning or the end of the buffer. (Bug#9955)
11260 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
11262 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
11263 label is not null (Bug#9951).

11284 its CHARPOS is positive.
11285 (mouse_face_from_buffer_pos, note_mouse_highlight):
11286 Rename cover_string to disp_string.

11296 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
11297 past the beginning of the current glyph matrix.
11299 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
11301 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
11302 (x_error_handler): Ignore BadMatch for X_SetInputFocus for

11322 so that this new function doesn't get optimized away by a
11323 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.

11345 2011-10-29 Glenn Morris <rgm@gnu.org>
11347 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
11348 Not clear what it was for, and it causes various bugs. (Bug#9839)
11350 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11352 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
11353 possible random value that matches one of those tested as
11354 condition to clear the mouse face.
11356 2011-10-28 Chong Yidong <cyd@gnu.org>
11358 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

11368 2011-10-28 Juanma Barranquero <lekktu@gmail.com>

11372 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11374 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
11375 <oslsachem@gmail.com> for helping to debug this.
11377 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

11383 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
11385 (w32font_open_internal, compute_metrics):
11386 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11387 instead of calling the "wide" APIs directly.
11389 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11391 * w32.h (syms_of_w32font): Add prototype.
11393 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

11396 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
11397 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
11398 (Fmove_to_window_line): Doc fix.
11400 2011-10-27 Chong Yidong <cyd@gnu.org>
11402 * process.c (make_process): Set gnutls_state to NULL.
11404 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11405 non-NULL, regardless of GNUTLS_INITSTAGE.
11406 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
11407 an error. Set process slots as soon as we allocate them.
11409 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
11411 2011-10-27 Chong Yidong <cyd@gnu.org>
11413 * gnutls.c (emacs_gnutls_deinit): New function.

11417 * process.c (make_process): Initialize GnuTLS credentials to NULL.
11418 (deactivate_process): Call emacs_gnutls_deinit.
11420 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11422 * image.c (x_create_x_image_and_pixmap):
11423 * w32.c (sys_rename, w32_delayed_load):
11424 * w32font.c (fill_in_logfont):

11430 extracted from Fw32_default_color_map.
11431 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
11433 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
11435 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
11437 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
11439 * keyboard.c (test_undefined): New function (bug#9751).
11440 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
11442 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
11444 * sysdep.c (init_sys_modes): Fix the check for the controlling
11445 terminal (Bug#6649).
11447 2011-10-20 Eli Zaretskii <eliz@gnu.org>
11449 * dispextern.h (struct bidi_it): New member next_en_type.
11451 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11452 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11453 current character, check also for next_en_type being WEAK_EN.
11454 (bidi_resolve_weak): Don't enter the expensive loop if the current
11455 position is before next_en_pos. Record the bidi type of the first
11456 non-ET, non-BN character we find, in addition to its position.
11457 (bidi_level_of_next_char): Invalidate next_en_type when
11458 next_en_pos is over-stepped.
11460 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11462 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11463 * editfns.c: Rewrite current-time-zone so that it invokes
11464 the equivalent of (format-time-string "%Z") to get the time zone name.
11465 This fixes a bug when the time zone name contains characters that
11466 need converting from the system time locale to Emacs internal format.
11467 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11468 that patch fixed format-time-string to do the conversion, but
11469 I forgot to fix current-time-zone.
11470 (format_time_string): New function, containing most of
11471 what Fformat_time_string used to contain.
11472 (Fformat_time_string): Rewrite in terms of format_time_string.
11473 This doesn't change this function's behavior.
11474 (current-time-zone): Rewrite to use format_time_string.
11475 This fixes the bug reported by Michael Schierl in
11476 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11477 Jason Rumney's 2007-06-07 change worked around this bug, but
11479 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11481 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11483 * xdisp.c (start_display): If the character at POS is displayed
11484 via a display vector, reset IT->current.dpvec_index to zero.
11485 (try_window_reusing_current_matrix): If a line ends in a display
11486 vector or the next line starts in a display vector, continue
11487 redrawing the window even though the character position of
11488 start_row was reached.
11491 2011-10-18 Chong Yidong <cyd@gnu.org>
11493 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11494 with nobreak-char-display too.
11496 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11498 Fix part 3 of bug#9771.
11499 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11500 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11501 non-neutral characters if the current character is a paragraph
11502 separator (a.k.a. Newline). This avoids running the same
11503 expensive loop twice, once when we consume the preceding newline
11504 and the other time when the line actually needs to be displayed.
11505 Avoid the loop when we see neutrals on the base embedding level
11506 following a character whose directionality is the same as the
11507 paragraph's. This avoids running the expensive loop when a line
11508 ends in a long sequence of neutrals, like control characters.
11509 Add assertion against STRONG_AL type. Slightly rearrange code
11510 that determines the type of a neutral given the first non-neutral
11512 (bidi_level_of_next_char): Set next_en_pos to zero when
11513 invalidating its info.
11515 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11517 * xdisp.c (push_display_prop): Determine whether to record string
11518 or buffer position by IT->string, not by IT->method. Allow
11519 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11520 (move_it_vertically_backward): Don't look for character position
11521 immediately after the newline when in a continuation line.
11524 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11526 * window.c (coordinates_in_window): Rewrite and delabelize
11527 vertical border check. (Bug#5357) (Bug#9618)
11529 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11531 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11532 errors in XSetWindowBorder (bug#9310).
11534 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11536 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11537 avoid crash when xmalloc overrun checking is enabled.
11539 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11541 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11542 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11543 cursor motion with <left> and <right> arrow keys.
11545 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11546 some callers set that themselves.
11548 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11550 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11551 display string and the previous row comes from the same string and
11552 is empty. (Bug#9739) (Bug#9738)
11554 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11556 * doc.c (get_doc_string): Encode file name (bug#9735).
11558 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11560 * bidi.c (bidi_level_of_next_char):
11561 * xdisp.c (get_visually_first_element): Remove old incorrect
11562 comments regarding the Unicode Line Separator character.
11564 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11566 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11568 * alloc.c (Fgc_status): Do not access beyond zombies array
11569 boundary if nzombies > MAX_ZOMBIES.
11570 * alloc.c (dump_zombies): Add missing format specifier.
11572 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11574 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11575 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11577 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11578 Some packages use them to denote characters with modifiers.
11580 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11582 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11583 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11584 matching a pp-number. Rename parameter var to var1.
11586 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11588 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11590 2011-10-08 Glenn Morris <rgm@gnu.org>
11592 * callint.c (Fcall_interactively): Give a more explicit error for the
11593 'c' case with a non-character input. (Bug#8479)
11595 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11597 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11599 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11600 lines that are hscrolled on the left.
11602 * dispnew.c (buffer_posn_from_coords): Account for a possible
11603 presence of header-line. (Bug#4426)
11605 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11607 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11608 Don't advertise functionality which we discourage or doesn't work.
11610 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11612 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11613 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11614 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11615 this makes Emacs dump core during garbage collection on rare
11616 occasions. sizeof is obviously inferior to offsetof here, so
11617 stick with offsetof.
11618 (GC_POINTER_ALIGNMENT): New macro.
11619 (mark_memory): Omit 3rd (offset) arg; caller changed.
11620 Don't assume EMACS_INT alignment is the same as pointer alignment.
11622 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11624 * keyboard.c (read_key_sequence_remapped): New var.
11625 (read_key_sequence): Compute remapping in the right buffer.
11626 (command_loop_1): Use read_key_sequence's remapping directly.
11628 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11630 * dired.c (file_name_completion): Don't expand file name.
11631 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11632 before checking file name handler.
11634 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11635 they've been requested explicitly (bug#9591).
11637 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11639 * keymap.c (Fsingle_key_description): Use make_specified_string
11640 instead of build_string to build string from push_key_description.
11643 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11645 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11646 This fixes a Y2038 bug on 64-bit hosts.
11647 * buffer.c (reset_buffer):
11648 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11649 (Fclear_buffer_auto_save_failure):
11650 Use 0, not -1, to represent an unset failure time, since time_t
11651 might not be signed.
11653 Remove dependency on glibc malloc internals.
11654 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11655 Move back here from lisp.h, but with their new implementations.
11656 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11657 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11658 * charset.c (charset_table_init): New static var.
11659 (syms_of_charset): Use it instead of xmalloc. This removes a
11660 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11661 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11662 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11663 Move back to alloc.c.
11664 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11665 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11667 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11669 * nsterm.m (windowDidResize): Call x_set_window_size only when
11670 ns_in_resize is true. Otherwise set pixelwidth/height and
11671 call change_frame_size (Bug#9628).
11673 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11675 Port --enable-checking=all to Fedora 14 x86-64.
11676 * charset.c (syms_of_charset): Also account for glibc malloc's
11677 internal overhead when calculating the initial malloc maximum.
11679 Port --enable-checking=all to Fedora 14 x86.
11680 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11682 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11683 (overrun_check_realloc, overrun_check_free):
11684 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11685 That way, xmalloc returns a properly-aligned pointer even if
11686 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11687 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11688 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11689 into account when calculating the initial malloc maximum.
11690 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11691 Move here from alloc.c, so that charset.c can use it too.
11692 Properly align; the old code wasn't right for common 32-bit hosts
11693 when configured with --enable-checking=all.
11694 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11695 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11697 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11699 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11702 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11704 * xdisp.c (compute_display_string_end): If there's no display
11705 string at CHARPOS, return -1.
11707 * bidi.c (bidi_fetch_char): When compute_display_string_end
11708 returns a negative value, treat the character as a normal
11709 character not covered by a display string. (Bug#9624)
11711 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11713 * lread.c (Fread_from_string): Fix typo in docstring.
11715 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11717 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11718 newline, reseat the iterator instead of bidi-iterating there one
11719 character at a time. (Bug#9610)
11720 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11721 TO_CHARPOS if the bidi iterator is at base embedding level.
11723 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11725 * lread.c (readevalloop): Use correct code for NBSP.
11726 (read1): Likewise. (Bug#9608)
11728 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11730 * dbusbind.c (Fdbus_register_signal): When service is not
11731 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11733 2011-09-25 Glenn Morris <rgm@gnu.org>
11735 * buffer.c (truncate-lines): Doc fix.
11737 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
11739 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
11740 (Fset_window_next_buffers): Doc fix.
11742 2011-09-24 Glenn Morris <rgm@gnu.org>
11744 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
11746 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
11748 Fix minor problems found by static checking.
11749 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
11750 * indent.c (Fvertical_motion): Fix == vs = typo.
11752 2011-09-24 Eli Zaretskii <eliz@gnu.org>
11754 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
11755 Default value is now t. Doc fix.
11757 * indent.c (Fvertical_motion): Compute and apply the overshoot
11758 logic when moving up, not only when moving down. Fix the
11759 confusing name and values of the it_overshoot_expected variable;
11760 logic changes accordingly. (Bug#9254) (Bug#9549)
11762 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
11763 CHARPOS is covered by a display string which includes newlines.
11764 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
11765 is covered by a display string with embedded newlines.
11767 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
11769 * dbusbind.c (Fdbus_register_signal): Add match rule to
11770 Vdbus_registered_objects_table. (Bug#9581)
11771 (Fdbus_register_method, Vdbus_registered_objects_table):
11774 2011-09-24 Jim Meyering <meyering@redhat.com>
11776 do not ignore write error for any output size
11777 The previous change was incomplete.
11778 While it makes emacs --batch detect the vast majority of stdout
11779 write failures, errors were still ignored whenever the output size is
11780 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
11781 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
11782 && echo FAIL: ignored write error
11783 FAIL: ignored write error
11784 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
11785 && echo FAIL: ignored write error
11786 FAIL: ignored write error
11787 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
11789 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
11791 * emacs.c (Fkill_emacs): In noninteractive mode exit
11792 non-successfully if a write error occurred on stdout. (Bug#9574)
11794 2011-09-21 Eli Zaretskii <eliz@gnu.org>
11796 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
11799 * dispextern.h (struct it): Update the comment documenting what
11802 2011-09-20 Eli Zaretskii <eliz@gnu.org>
11804 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
11805 a display string, extend search for cursor position to end of row.
11806 (find_row_edges): If the row ends in a newline from a display
11807 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
11808 Handle the case of a display string with multiple newlines.
11809 (Fcurrent_bidi_paragraph_direction): Fix search for previous
11810 non-empty line. Fixes confusing cursor motion with arrow keys at
11811 the beginning of a line that starts with whitespace.
11813 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
11815 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
11818 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
11820 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
11821 boolean (Bug#9154).
11823 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11825 * xdisp.c (display_line): Record maximum and minimum buffer
11826 positions even if no glyphs were produced (e.g., by a zero-width
11827 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
11828 buffer positions that will be removed from the glyph row because
11830 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
11831 column is beyond frame width: don't subtract 1 "pixel" when
11832 computing width of the stretch.
11833 (reseat_at_next_visible_line_start): Undo the change made on
11834 2011-09-17 that saved paragraph information and restored it after
11835 the call to `reseat'. (Bug#9545)
11837 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11839 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
11840 and turn window cursor on if cleared (Bug#9415).
11842 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
11844 * search.c (boyer_moore): Take unibyte characters from pattern
11845 literally. (Bug#9458)
11847 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11849 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
11851 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
11853 Fix minor problem found by static checking.
11854 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
11855 initialized, to pacify gcc -Wuninitialized.
11857 * fileio.c: Report proper errno when syscall falls.
11858 (Finsert_file_contents): Save and restore errno,
11859 so that report_file_error outputs the correct diagnostic.
11860 (Fwrite_region) [CLASH_DETECTION]: Likewise.
11862 2011-09-18 Eli Zaretskii <eliz@gnu.org>
11864 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
11866 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11868 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
11869 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
11871 2011-09-17 Eli Zaretskii <eliz@gnu.org>
11873 * xdisp.c (reseat_at_next_visible_line_start): Keep information
11874 about the current paragraph and restore it after the call to reseat.
11876 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
11877 (bidi_find_paragraph_start): Search back for paragraph beginning
11878 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
11879 (bidi_move_to_visually_next): Only trigger paragraph-related
11880 computations when the last character is a newline or at EOB, not
11881 just any NEUTRAL_B. (Bug#9470)
11883 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
11884 truncated lines if point is covered by a display string. (Bug#9524)
11886 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
11888 * xselect.c: Relax test for outgoing X longs (Bug#9498).
11889 (cons_to_x_long): New function.
11890 (lisp_data_to_selection_data): Use it. Correct the test for
11891 short-versus-long data; it was negated. Break out of vector
11892 loop, for efficiency, when a long datum is discovered.
11894 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
11896 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
11898 2011-09-16 Eli Zaretskii <eliz@gnu.org>
11900 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
11901 GCC PR/17406) by declaring this function with external scope.
11903 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11905 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
11906 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
11908 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
11910 * editfns.c (Fformat): Correctly handle text properties on "%%".

11916 * term.c (encode_terminal_code):
11917 * composite.c (composition_update_it, get_composition_id):
11918 * xdisp.c (get_next_display_element)
11919 (fill_composite_glyph_string): Add comments about special meaning
11920 of TAB characters in a composition.
11922 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
11924 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
11925 This occurs when processing a multibyte format.
11926 Problem reported by Wolfgang Jenker.
11928 2011-09-15 Johan Bockgård <bojohan@gnu.org>
11930 * xdisp.c (try_cursor_movement): Only check for exact match if
11931 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
11933 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11935 Remove unused external symbols.
11936 * dispextern.h (calc_pixel_width_or_height): Remove decl.
11937 * xdisp.c (calc_pixel_width_or_height): Now static.
11938 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
11939 * indent.c (check_display_width):
11940 * w32term.c: Fix comment to match code.
11941 * xterm.c, xterm.h (x_catching_errors): Remove.
11943 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
11945 * xselect.c: Use signed conversions more consistently (Bug#9498).
11946 (selection_data_to_lisp_data): Assume incoming selection data are
11947 signed integers, not unsigned. This is to be consistent with
11948 outgoing selection data, which was modified to use signed integers
11949 in as part of the fix to Bug#9196 in response to Jan D.'s comment
11950 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
11951 expects long, not unsigned long.
11953 2011-09-14 Eli Zaretskii <eliz@gnu.org>
11955 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
11956 computation of loop end. Reported by Johan Bockgård
11959 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
11961 * frame.c (Fother_visible_frames_p): Function deleted.
11963 2011-09-12 Eli Zaretskii <eliz@gnu.org>
11965 * indent.c (compute_motion): Process display vector front to back
11966 rather than the other way around. (Bug#2496)
11968 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
11970 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
11972 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
11974 * minibuf.c (Fread_from_minibuffer): Doc fix.
11976 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11978 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
11979 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
11981 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
11983 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
11984 value for non-existent files.
11986 2011-09-11 Eli Zaretskii <eliz@gnu.org>
11988 * fileio.c (Finsert_file_contents): If the file cannot be opened,
11989 set its "size" to -1. This will set the modtime_size field of
11990 the corresponding buffer to -1, which is what
11991 verify-visited-file-modtime expects for files that do not exist.
11994 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
11996 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
11998 * lisp.h: ... from here. push_key_description is no longer
11999 defined in keyboard.c, so its declaration should not be in
12000 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12001 logically belongs with push_key_description.
12003 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12005 * buffer.h: Include <sys/types.h> instead of <time.h>.
12006 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12007 Problem reported by Herbert J. Skuhra.
12009 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12011 * xml.c (parse_region): Make the parsing work for
12012 non-comment-starting XML files again (bug#9144).
12014 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12016 * image.c (gif_load): Fix calculation of bottom and right corner.
12019 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12021 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12022 redisplay in small windows.
12024 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12026 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12028 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12030 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12031 Operate on live windows only.
12033 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12035 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12037 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12039 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12040 only under bidi iteration.
12042 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12044 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12046 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12048 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12049 Without this fix, the command to link temacs failed due to an
12050 undefined symbol __builtin_isnan. This is because
12051 /usr/include/iso/math_c99.h #defines isnan(x) to
12052 __builtin_isnan(x), but the bundled gcc, which identifies itself
12053 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12055 * floatfns.c (isnan): #undef, and then #define to a clone of
12057 (Fisnan): Always define, since it's always available now.
12058 (syms_of_floatfns): Always define isnan at the Lisp level.
12060 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12062 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12064 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12066 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12067 The previous code assumed that file offsets (off_t values) fit in
12068 EMACS_INT variables, which is not true on typical 32-bit hosts.
12069 The code messed up by falsely reporting buffer overflow in cases
12070 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12071 when "big" contains more than 2**29 bytes, even though this
12072 inserts just one byte and does not overflow the buffer.
12073 (Finsert_file_contents): Store file offsets as off_t
12074 values, not as EMACS_INT values. Check for overflow when
12075 converting between EMACS_INT and off_t. When checking for
12076 buffer overflow or for overlap, take the offsets into account.
12077 Don't use EMACS_INT for small values where int suffices.
12078 When checking for overlap, fix a typo: ZV was used where
12079 ZV_BYTE was intended.
12080 (Fwrite_region): Don't assume off_t fits into 'long'.
12081 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12083 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12085 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12087 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12089 sprintf-related integer and memory overflow issues (Bug#9412).
12091 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12092 (esprintf, exprintf, evxprintf): New functions.
12093 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12094 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12095 (modify_event_symbol): Do not assume that the length of
12096 name_alist_or_stem is safe to alloca and fits in int.
12097 (Fexecute_extended_command): Likewise for function name and binding.
12098 (Frecursion_depth): Wrap around reliably on integer overflow.
12099 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12100 since some callers pass EMACS_INT values.
12101 (Fsingle_key_description): Don't crash if symbol name contains more
12102 than MAX_ALLOCA bytes.
12103 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12104 (get_minibuffer): Arg is now EMACS_INT, not int.
12105 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12106 (esprintf, exprintf, evxprintf): New decls.
12107 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12109 * dbusbind.c (signature_cat): New function.
12110 (xd_signature, Fdbus_register_signal):
12111 Do not overrun buffer; instead, report string overflow.
12113 * dispnew.c (add_window_display_history): Don't overrun buffer.
12114 Truncate instead; this is OK since it's just a log.
12116 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12117 even if the time zone offset is outlandishly large.
12118 Don't mishandle offset == INT_MIN.
12120 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12121 when creating daemon; the previous buffer-overflow check was incorrect.
12123 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12124 which has the guts of the old verror function.
12126 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12127 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12129 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12130 (font_unparse_xlfd): Don't blindly alloca long strings.
12131 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12132 fits in int, when using sprintf. Use single snprintf to count
12133 length of string rather than counting it via multiple sprintfs;
12134 that's simpler and more reliable.
12135 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12136 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12137 sprintf, in case result does not fit in int.
12139 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12140 (fontset_from_font): Print it.
12142 * frame.c (tty_frame_count): Now printmax_t, not int.
12143 (make_terminal_frame, set_term_frame_name): Print it.
12144 (x_report_frame_params): In X, window IDs are unsigned long,
12145 not signed long, so print them as unsigned.
12146 (validate_x_resource_name): Check for implausibly long names,
12147 and don't assume name length fits in 'int'.
12148 (x_get_resource_string): Don't blindly alloca invocation name;
12149 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12152 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12153 (xg_check_special_colors, xg_set_geometry):
12154 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12156 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12157 Use esprintf, not sprintf, in case result does not fit in int.
12159 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12160 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12161 it as a large positive number.
12162 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12163 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12165 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12166 in case result does not fit in int.
12168 * print.c (float_to_string): Detect width overflow more reliably.
12169 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12170 buffer overrun. Don't assume list length fits in 'int'. Treat
12171 print length of 0 as 0, not as infinity; to be consistent with other
12172 uses of print length in this function. Don't overflow print length
12173 index. Don't assume hash table size fits in 'long', or that
12174 vectorlike size fits in 'unsigned long'.
12176 * process.c (make_process): Use printmax_t, not int, to format
12177 process-name gensyms.
12179 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12181 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12182 to avoid potential buffer overrun.
12184 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12185 if X resource line is longer than 512 bytes.
12187 * xfns.c (x_window): Make sprintf buffer a bit bigger
12188 to avoid potential buffer overrun.
12190 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12192 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12194 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12196 Integer overflow fixes for scrolling, etc.
12197 Without these, Emacs silently mishandles large integers sometimes.
12198 For example, "C-u 4294967297 M-x recenter" was treated as if
12199 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12201 * xdisp.c (try_window_id): Check Emacs fixnum range before
12202 converting to 'int'.
12204 * window.c (window_scroll_line_based, Frecenter):
12205 Check that an Emacs fixnum is in range before assigning it to 'int'.
12206 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12207 values converted from Emacs fixnums.
12208 (Frecenter): Don't wrap around a line count if it is out of 'int'
12209 range; instead, treat it as an extreme value.
12210 (Fset_window_configuration, compare_window_configurations):
12211 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12213 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12214 that can exceed INT_MAX. Check that EMACS_INT value is in range
12215 before assigning it to the (possibly-narrower) index.
12216 (match_limit): Don't assume that a fixnum can fit in 'int'.
12218 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12221 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12222 (Fvertical_motion): Don't wrap around LINES values that don't fit
12223 in 'int'. Instead, treat them as extreme values. This is good
12224 enough for windows, which can't have more than INT_MAX lines anyway.
12226 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12228 * Require libxml/parser.h to avoid compilation warning.
12230 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12232 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12233 since this reportedly can destroy thread storage.
12235 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12237 * syntax.c (find_defun_start): Update all cache variables if
12238 exiting early (Bug#9401).
12240 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12242 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12244 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12245 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12246 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12248 * term.c (tty_append_glyph): New function.
12249 (produce_stretch_glyph): Static function and its prototype deleted.
12251 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12254 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12256 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12257 when checking :margin (Bug#9390).
12258 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12259 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12260 so that the name doesn't mislead. All uses changed.
12262 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12264 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12267 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12269 * xdisp.c (move_it_to): Don't bail out early when reaching
12270 position beyond to_charpos, if we are scanning backwards.
12271 (move_it_vertically_backward): When DY == 0, make sure we get to
12272 the first character in the line after the newline.
12274 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12276 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12277 (ccl_driver): Do not generate an out-of-range pointer.
12278 (Fccl_execute_on_string): Remove unnecessary check for
12279 integer overflow, noted by Stefan Monnier in
12280 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12281 Remove a FIXME that didn't need fixing.
12282 Simplify the newly-introduced buffer reallocation code.
12284 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12286 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12288 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12290 Integer and memory overflow issues (Bug#9196).
12292 * doc.c (get_doc_string): Rework so that
12293 get_doc_string_buffer_size is the actual buffer size, rather than
12294 being 1 less than the actual buffer size; this makes xpalloc more
12297 * image.c (x_allocate_bitmap_record, cache_image):
12298 * xselect.c (Fx_register_dnd_atom):
12299 Simplify previous changes by using xpalloc.
12301 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12302 since either will do and ptrdiff_t is convenient with xpalloc.
12304 * charset.c (charset_table_size)
12305 (struct charset_sort_data.priority): Now ptrdiff_t.
12306 (charset_compare): Don't overflow if priorities differ greatly.
12307 (Fsort_charsets): Don't assume list length fits in int.
12308 Check for size-calculation overflow when allocating sort data.
12309 (syms_of_charset): Allocate an initial charset table that is
12310 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12312 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12314 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12315 The actual value is always <= INT_MAX, and leaving it unsigned made
12316 overflow checking harder.
12318 * dispextern.h (struct glyph_matrix.rows_allocated)
12319 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12320 with xpalloc. The values are still always <= INT_MAX.
12322 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12324 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12325 (SAFE_NALLOCA): New macro.
12327 * region-cache.c (struct boundary.pos, find_cache_boundary)
12328 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12329 (set_cache_region, invalidate_region_cache)
12330 (revalidate_region_cache, know_region_cache, region_cache_forward)
12331 (region_cache_backward, pp_cache):
12332 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12333 so that ptrdiff_t * can be passed to xpalloc.
12334 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12335 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12336 (pp_cache): Don't assume cache_len fits in int.
12337 * region-cache.h: Adjust extern decls to match.
12339 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12340 EMACS_INT, since either will do, for xpalloc.
12342 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12343 (xnmalloc, xnrealloc, xpalloc): New functions.
12345 * bidi.c (bidi_shelve_header_size): New constant.
12346 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12347 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12349 * bidi.c (bidi_cache_shrink):
12350 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12352 Don't update size of array until after memory allocation succeeds,
12353 because xmalloc/xrealloc may not return.
12354 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12355 now that we have proper integer overflow checking.
12356 (record_overlay_string, overlay_strings): Catch overflows when
12357 calculating size of overlay_str_buf.
12359 * callproc.c (Fcall_process): Check for size overflow when
12360 calculating size of args2.
12361 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12362 Normally we prefer signed values, but sticking with ptrdiff_t would
12363 require adding more-complicated checks.
12365 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12366 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12367 Redo buffer-overflow calculations to avoid integer overflow.
12368 Add a FIXME comment where memory seems to be over-allocated.
12370 * character.c (Fstring): Check for size-calculation overflow.
12372 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12373 unnecessary integer overflow. Check for size overflow.
12374 (encode_coding_object): Don't update size until xmalloc succeeds.
12376 * composite.c (get_composition_id): Check for overflow in glyph
12377 length calculations.
12379 Integer and memory overflow fixes for display code.
12380 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12381 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
12382 (scrolling_window): Check for overflow in size calculations.

12394 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12395 (get_doc_string): Check for size calculation overflow.
12396 Don't update size until allocation succeeds.
12397 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12398 EMACS_INT, where ptrdiff_t will do.
12399 (Fsubstitute_command_keys): Check for string overflow.
12401 * editfns.c (set_time_zone_rule): Don't assume environment length
12403 (message_length): Now ptrdiff_t, not int.
12404 (Fmessage_box): Don't update size until allocation succeeds.
12405 Don't assume message length fits in int.
12406 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12408 * emacs.c (main): Do not reallocate argv, since there is a null at
12409 the end that can be overwritten, and this way there's no need to
12410 worry about size-calculation overflow.
12411 (sort_args): Check for size-calculation overflow.
12413 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12415 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12417 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12418 (x_set_scroll_bar_width, x_figure_window_size):
12419 Check for integer overflow.
12420 (x_set_alpha): Do not assume XINT fits in int.
12422 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12423 This is for the members text_lines, text_cols, total_lines, total_cols,
12424 where the system imposes an 'int' limit.
12426 * fringe.c (Fdefine_fringe_bitmap):
12427 Don't update size until alloc works.
12429 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12430 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12432 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12433 Check for size-calculation overflow.
12434 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12435 do, as we prefer signed integers.
12436 (id_to_widget.max_size, id_to_widget.used)
12437 (xg_store_widget_in_map, xg_remove_widget_from_map)
12438 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12439 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12440 Use and return ptrdiff_t, not int.
12441 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12442 * gtkutil.h: Change prototypes to match the above.
12444 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12445 are duplicate now that they've been promoted to lisp.h.
12446 (x_allocate_bitmap_record, x_alloc_image_color)
12447 (make_image_cache, cache_image, xpm_load):
12448 Don't update size until alloc is done.

12458 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
12459 Use ptrdiff_t, not int, to count maps.
12460 (read_char_minibuf_menu_prompt): Check for overflow in size
12461 calculations. Don't update size until allocation succeeds.
12462 Redo calculations to avoid overflow.
12463 * keyboard.h: Change prototypes to match the above.
12465 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
12467 (current_minor_maps): Check for size calculation overflow.
12468 * keymap.h: Change prototypes to match the above.
12470 * lread.c (read1, init_obarray): Don't update size until alloc done.
12472 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

12491 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12492 for command line length. Do not attempt to address one before the
12493 beginning of an array, as that's not portable.
12495 * term.c (max_frame_lines): Remove; unused.
12496 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12498 (encode_terminal_code, calculate_costs): Check for size
12499 calculation overflow.

12521 Use ptrdiff_t, not int, for sizes.
12522 (Finternal_make_lisp_face, cache_face):
12523 Check for size calculation overflow.
12524 (cache_face): Treat size calculation overflows as if they were
12525 memory exhaustion (the usual treatment), rather than aborting.
12527 * xfns.c (x_encode_text, x_set_name_internal)
12528 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12529 sizes, since they can exceed INT_MAX in size. Check for size
12530 calculation overflow.
12532 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12533 (xg_select): Check for size calculation overflow.
12534 Don't update size until alloc done.
12536 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12537 as sprintf is limited to int lengths.
12539 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12540 (X_LONG_MIN): New macros.
12541 Use them to make the following changes clearer.
12542 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12543 This change doesn't affect the value now, but it may help remind
12544 future maintainers not to raise the value too much later.
12545 (SELECTION_QUANTUM): Remove, replacing with ...
12546 (selection_quantum): ... new function, which avoids overflow.
12548 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12549 assumption that selection length fits in 'int'.

12556 (receive_incremental_selection, x_property_data_to_lisp):
12557 Redo calculations to avoid overflow.
12558 (x_reply_selection_request): When sending hint, ceiling it at
12559 X_LONG_MAX rather than relying on wraparound overflow to send
12561 (x_get_window_property, receive_incremental_selection)
12562 (lisp_data_to_selection_data, x_property_data_to_lisp):
12563 Check for size-calculation overflow.
12564 (x_get_window_property, receive_incremental_selection)

12566 Don't store size until memory allocation succeeds.
12567 (x_get_window_property): Plug memory leak on memory exhaustion.
12568 Don't double-block input; malloc is safe here. Don't assume 2**34
12569 - 4 fits in unsigned long. Add an xassert to check
12570 XGetWindowProperty overflow. Be more careful about overflow
12571 calculations, and distinguish size from memory overflow better.
12572 (receive_incremental_selection): When tracing, don't assume
12573 unsigned int is less than INT_MAX.
12574 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12575 harmful) conversions of unsigned short to int.
12576 (lisp_data_to_selection_data): Don't assume that integers
12577 in the range -65535 through -1 fit in an X unsigned short.
12578 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12579 result parameters unless successful. Rely on cons_to_unsigned
12580 to report problems with elements; the old code wasn't right anyway.
12581 (x_check_property_data): Check for int overflow; we cannot use
12582 a wider type due to X limits.
12583 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

12588 (x_term_init): Check for size calculation overflow.
12589 (x_color_cells): Don't store size until memory allocation succeeds.
12590 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
12591 Don't assume alloca size is less than MAX_ALLOCA.
12592 (x_term_init): Don't assume length fits in int (sprintf is limited
12595 Use ptrdiff_t for composition IDs.

12614 * image.c (xpm_get_color_table_h):
12615 * lisp.h (hash_lookup, hash_put):
12616 * minibuf.c (Ftest_completion):
12617 Use ptrdiff_t for hash table indexes, not int (which is too
12618 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12619 32-bit --with-wide-int hosts).
12621 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12622 Add a FIXME comment about memory leaks.
12623 (syms_of_charset): Don't assume xmalloc returns.

12627 * character.h (CHAR_WIDTH):
12628 * indent.c (MULTIBYTE_BYTES_WIDTH):
12629 Use sanitize_char_width to avoid undefined and/or bad behavior
12630 with outlandish widths.
12631 * character.h (sanitize_tab_width): Rename from sanitize_width,
12632 now that we have two such functions. All uses changed.

12643 * fileio.c: Integer overflow issues with file modes.
12644 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
12646 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
12647 Remove unreachable code.
12648 (read_hex, load_charset_map_from_file): Check for integer overflow.
12650 * xterm.c: Don't go over XClientMessageEvent limit.
12651 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
12652 (x_send_scroll_bar_event): Likewise. Check that the size does not
12653 exceed limits imposed by XClientMessageEvent, as well as the usual
12654 ptrdiff_t and size_t limits.
12656 * keyboard.c: Overflow, signedness and related fixes.
12657 (make_lispy_movement): Use same integer type in forward decl
12658 that is used in the definition.
12659 (read_key_sequence, keyremap_step):
12660 Change bufsize argument back to int, undoing my 2011-03-30 change.
12661 We prefer signed types, and int is wide enough here.
12662 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12663 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12664 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12665 length, not size_t. Use ptrdiff_t for index, not int.
12666 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12667 possibility of integer overflow.
12669 Overflow, signedness and related fixes for images.
12671 * dispextern.h (struct it.stack[0].u.image.image_id)

12679 * xdisp.c (calc_pixel_width_or_height):
12680 * xfns.c (image_cache_refcount):
12681 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

12690 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
12691 (lookup_image): Remove unnecessary tests.
12692 (xbm_image_p): Locals are now of int, not EMACS_INT,
12693 since parse_image_check makes sure they fit into int.
12694 (png_load, gif_load, svg_load_image):
12695 Prefer int to unsigned where either will do.
12696 (tiff_handler): New function, combining the cores of the
12697 old tiff_error_handler and tiff_warning_handler.
12698 This function is rewritten to use vsnprintf and thereby avoid
12699 stack buffer overflows. It uses only the features of vsnprintf
12700 that are common to both POSIX and native Microsoft.
12701 (tiff_error_handler, tiff_warning_handler): Use it.
12702 (tiff_load, gif_load, imagemagick_load_image):
12703 Don't assume :index value fits in 'int'.
12704 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
12705 (imagemagick_load_image): Check that crop parameters fit into
12706 the integer types that MagickCropImage accepts. Don't assume
12707 Vimagemagick_render_type has a nonnegative value. Don't assume
12708 size_t fits in 'long'.
12709 (gs_load): Use printmax_t to print the widest integers possible.
12710 Check for integer overflow when computing image height and width.
12712 2011-08-26 Eli Zaretskii <eliz@gnu.org>
12714 * xdisp.c (redisplay_window): Don't force window start if point
12715 will be invisible in the resulting window. (Bug#9324)

12719 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
12720 the display spec is of the form `(space ...)'.
12721 (handle_display_spec): Return the value returned by
12722 handle_single_display_spec, not just 1 or zero.
12723 (handle_single_display_spec): If the display spec is of the form
12724 `(space ...)', and specifies display in the text area, return 2
12726 (try_cursor_movement): Check for the need to scroll more
12727 accurately, and prefer exact match for point under bidi.
12728 Don't advance `row' beyond the last row of the window.
12730 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
12731 into disp_prop; all users changed.
12733 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
12734 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
12735 for the text covered by the display property.

12745 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
12746 buffers, return left-to-right.
12747 (set_cursor_from_row): Consider candidate row a win if its glyph
12748 represents a newline and point is on that newline. Fixes cursor
12749 positioning on the newline at EOL of R2L text within L2R
12750 paragraph, and vice versa.
12751 (try_cursor_movement): Check continued rows, in addition to
12752 continuation rows. Fixes unwarranted scroll when point enters a
12753 continued line of R2L text within an L2R paragraph, or vice versa.
12754 (cursor_row_p): Consider the case of point being equal to
12755 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
12756 from the end of a short line to the beginning of a continued line
12757 of R2L text within L2R paragraph.
12758 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
12759 composed characters.

12774 2011-08-22 Kenichi Handa <handa@m17n.org>
12776 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
12777 extra slot even if the purpose is char-code-property-table.
12779 2011-08-23 Eli Zaretskii <eliz@gnu.org>
12781 * xdisp.c (redisplay_window): When computing centering_position,
12782 account for the height of the header line. (Bug#8874)
12784 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
12785 instead of CHAR_TO_BYTE. Fixes a crash when a completion
12786 candidate is selected by the mouse, and that candidate has a
12787 composed character under the mouse.
12789 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
12790 coordinates reported by pos-visible-in-window-p for a composed
12791 character in column zero.
12793 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
12795 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
12797 2011-08-22 Eli Zaretskii <eliz@gnu.org>
12799 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
12800 consider it a hit if to_charpos is anywhere in the range of the
12801 composed buffer positions.
12803 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
12805 * image.c (gif_load): Don't assume that each subimage has the same
12806 dimensions as the base image. Handle disposal method that is
12807 "undefined" by the gif spec (Bug#9335).
12809 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
12811 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
12812 (Fcondition_case): Document `debug' symbol in error handler.
12814 2011-08-19 Eli Zaretskii <eliz@gnu.org>
12816 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
12817 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
12818 from an Org mode buffer to a Speedbar frame.
12820 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
12821 a composition, take its buffer position from IT->cmp_it.charpos.
12822 Fixes cursor positioning at the beginning of a line that begins
12823 with a composed character.
12825 2011-08-18 Eli Zaretskii <eliz@gnu.org>
12827 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
12828 character bidirectional type, use STRONG_L instead. Fixes crashes
12829 in a buffer produced by `describe-categories'.
12831 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
12832 members before the level stack, so they would be saved and
12833 restored when copying iterator state. Fixes incorrect reordering
12834 around TABs covered by display properties.
12836 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
12838 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

12842 * eval.c (internal_condition_case, internal_condition_case_1)
12843 (internal_condition_case_2, internal_condition_case_n):
12844 Remove unnecessary aborts (Bug#9081).
12846 2011-08-17 Eli Zaretskii <eliz@gnu.org>
12848 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
12849 has no `load' handler, try opening the file locally. (Bug#9311)
12851 2011-08-16 Ken Brown <kbrown@cornell.edu>
12853 * gmalloc.c: Expand comment.

12857 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
12858 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
12860 2011-08-16 Ken Brown <kbrown@cornell.edu>
12862 Fix memory allocation problems in Cygwin build (Bug#9273).
12864 * unexcw.c ( __malloc_initialized): Declare external variable.
12865 (fixup_executable): Force the dumped emacs to reinitialize malloc.
12867 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
12869 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

12898 coordinates of the iterator when restoring from ppos_it.
12901 2011-08-14 Kenichi Handa <handa@m17n.org>
12903 * process.c (create_process): Call setup_process_coding_systems
12904 after the pid of the process is set to -1 (Bug#8162).
12906 2011-08-14 Eli Zaretskii <eliz@gnu.org>
12908 * xdisp.c (move_it_in_display_line_to): Don't invoke
12909 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
12910 ppos_it. Fixes vertical cursor motion when line beginning is
12911 covered by an image. (Bug#9296)
12913 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
12915 * nsterm.h (ns_run_ascript): Declare.

12918 * nsfns.m (as_script, as_result, as_status): New static variables.
12919 (ns_run_ascript): New function.
12920 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
12921 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
12922 the event loop. Get status from as_status (Bug#7276).
12924 * nsterm.m (sendEvent): If event is NSApplicationDefined and
12925 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
12926 the event loop (Bug#7276).
12928 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
12930 * gnutls.c (QCgnutls_bootprop_priority)

12951 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
12952 (Fnetwork_interface_list): Allocate in increments of bytes instead
12953 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
12954 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
12956 (struct ifflag_def): notrailers is smart on OSX.
12957 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
12958 Get hardware address with getifaddrs if available.
12960 2011-08-12 Eli Zaretskii <eliz@gnu.org>
12962 * xdisp.c (iterate_out_of_display_property): xassert that
12963 IT->position is set to within IT->object's boundaries. Break from
12964 the loop as soon as EOB is reached; avoids infloops in redisplay
12965 when IT->position is set up wrongly due to some bug.
12966 Set IT->current to match the bidi iterator unconditionally.
12967 (push_display_prop): Allow GET_FROM_STRING as IT->method on
12968 entry. Force push_it to save on the stack the current
12969 buffer/string position, to be restored by pop_it. Fix flags in
12970 the iterator structure wrt the object coming from a display
12971 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
12972 properties. (Bug#9284)
12974 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
12976 * fontset.c (fontset_get_font_group): Add proper type checks.

12989 no-display-properties-and-no-overlays under bidi display.
12990 Set disp_pos in the bidi iterator to avoid searches for display
12991 properties and overlays.
12993 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
12995 * editfns.c (Fset_time_zone_rule): Document relationship with the
12998 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
12999 the font entity extracted from the cache (Bug#8109).
13001 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
13003 * composite.c (autocmp_chars): Don't reset point. That is done by
13004 restore_point_unwind (Bug#5984).
13006 2011-08-07 Juri Linkov <juri@jurta.org>
13008 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13009 to show the arg `TIME' instead of `TIMEVAL'.
13011 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13013 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13014 display property strides EOL and includes a newline, as in
13015 longlines-mode. (Bug#9254)
13016 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13017 word-wrap under bidirectional display. (Bug#9224)
13019 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13020 is non-zero, even if the data buffer is NULL. Fixes a crash in
13021 vertical-motion with longlines-mode. (Bug#9254)
13023 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13025 * bidi.c <bidi_cache_total_alloc>: Now static.
13026 (bidi_initialize): Initialize bidi_cache_total_alloc.
13028 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13031 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13032 amount allocated this far in `bidi_cache_total_alloc'.
13033 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13034 non-zero, only free the data buffer without restoring the cache
13035 contents. All callers changed.
13037 * dispextern.h (bidi_unshelve_cache): Update prototype.
13039 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
13040 (move_it_in_display_line, move_it_to)
13041 (move_it_vertically_backward, move_it_by_lines): Replace the call
13042 to xfree to an equivalent call to bidi_unshelve_cache.
13043 (move_it_in_display_line_to): Fix logic of returning
13044 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
13046 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13048 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
13049 came from a string character with a `cursor' property. (Bug#9229)
13051 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13053 * Makefile.in (LIB_PTHREAD): New variable.
13054 (LIBES): Add LIB_PTHREAD (Bug#9216).
13056 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
13057 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
13059 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
13061 * regex.c (re_iswctype): Remove some redundant boolean conversions.
13063 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
13065 * xterm.c (x_find_topmost_parent): New function.
13066 (x_set_frame_alpha): Find topmost parent window with
13067 x_find_topmost_parent and set the property there also (bug#9181).
13068 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
13070 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
13072 * callproc.c (Fcall_process): Avoid vfork clobbering
13073 the local vars buffer, coding_systems, current_dir.
13075 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
13077 * keymap.c (Fmake_composed_keymap): Move to subr.el.
13079 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
13081 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
13082 so that it is not optimized away.
13084 * xdisp.c (compute_display_string_pos): Remove unused local.
13086 2011-08-02 Eli Zaretskii <eliz@gnu.org>
13088 Fix slow cursor motion and scrolling in large buffers with
13089 selective display, like Org Mode buffers. (Bug#9218)
13091 * dispextern.h (struct bidi_it): New member disp_prop_p.
13093 * xdisp.c: Remove one-slot cache of display string positions.
13094 (compute_display_string_pos): Accept an additional argument
13095 DISP_PROP_P; callers changed. Scan at most 5K characters forward
13096 for a display string or property. If found, set DISP_PROP_P
13099 * bidi.c (bidi_fetch_char): Accept an additional argument
13100 DISP_PROP_P, and pass it to compute_display_string_pos.
13101 Only handle text covered by a display string if DISP_PROP_P is returned
13102 non-zero. All callers of bidi_fetch_char changed.
13104 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
13106 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
13108 2010-12-03 Don March <don@ohspite.net>
13110 * keymap.c (Fdefine_key): Fix non-prefix key error message when
13111 last character M-[char] is translated to ESC [char] (bug#7541).
13113 2011-08-02 Kenichi Handa <handa@m17n.org>
13115 * lisp.h (uniprop_table): Extern it.
13117 * chartab.c (uniprop_table): Make it non-static.
13119 2011-08-01 Eli Zaretskii <eliz@gnu.org>
13121 * xdisp.c (forward_to_next_line_start): Accept additional argument
13122 BIDI_IT_PREV, and store into it the state of the bidi iterator had
13124 (reseat_at_next_visible_line_start): Use the bidi iterator state
13125 returned by forward_to_next_line_start to restore the state of
13126 it->bidi_it after backing up to previous newline. (Bug#9212)
13128 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
13130 * regex.c (re_comp): Protoize.
13131 (re_exec): Fix return type.
13132 (regexec): Fix type of `ret'. (Bug#9203)
13134 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13136 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13137 This is needed if max-image-size is a floating-point number.
13139 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13141 * print.c (print_object): Print empty symbol as ##.
13143 * lread.c (read1): Read ## as empty symbol.
13145 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13147 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
13148 setting frame foreground color (Bug#9175).
13149 (x_set_background_color): Likewise.
13151 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13152 contents (Bug#9176).
13153 (EmacsTooltip -init): Remove bezels and add shadows to
13156 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13157 or scroll bar (Bug#8470).
13159 * nsfont.m (nsfont_open): Remove assignment to voffset and
13160 unnecessary vars hshink, expand, hd, full_height, min_height.
13161 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13163 * nsterm.h (nsfont_info): Remove voffset field.
13165 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13167 Implement strike-through and overline on NextStep (Bug#8863).
13169 * nsfont.m (nsfont_open): Use underline position provided by font,
13170 instead of hard-coded value of 2.
13171 (nsfont_draw): Call ns_draw_text_decoration instead.
13173 * nsterm.h: Add declaration for ns_draw_text_decoration.
13175 * nsterm.m (ns_draw_text_decoration): New function for drawing
13176 underline, overline, and strike-through.
13177 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13178 ns_draw_text_decoration. Change treatment of cursor drawing to
13179 accommodate underlining, etc.
13181 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13183 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13186 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13188 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13189 Without this fix, if a signal arrives just after memory fills up,
13190 'malloc' might be invoked reentrantly.
13192 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13193 In other words, assume that every image size is allowed, on non-X
13194 hosts. This assumption is probably wrong, but it lets Emacs compile.
13196 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13198 * regex.c (re_iswctype): Convert return values to boolean.
13200 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13202 * xdisp.c (compute_display_string_pos): Don't use cached display
13203 string position if the buffer had its restriction changed.
13206 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13208 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13210 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13212 Integer signedness and overflow and related fixes. (Bug#9079)
13214 * bidi.c: Integer size and overflow fixes.
13215 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13216 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13217 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13218 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13219 (bidi_find_other_level_edge):
13220 Use ptrdiff_t instead of EMACS_INT where either will do.
13221 This works better on 32-bit hosts configured --with-wide-int.
13222 (bidi_cache_ensure_space): Check for size-calculation overflow.
13223 Use % rather than repeated addition, for better worst-case speed.
13224 Don't set bidi_cache_size until after xrealloc returns, because it
13226 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13227 (bidi_cache_ensure_space): Also check that the bidi cache size
13228 does not exceed that of the largest Lisp string or buffer. See Eli
13229 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13231 * alloc.c (__malloc_size_t): Remove.
13232 All uses replaced by size_t. See Andreas Schwab's note
13233 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13235 * image.c: Improve checking for integer overflow.
13236 (check_image_size): Assume that f is nonnull, since
13237 it is always nonnull in practice. This is one less thing to
13238 worry about when checking for integer overflow later.
13239 (x_check_image_size): New function, which checks for integer
13240 overflow issues inside X.
13241 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13242 This removes the need for a memory_full check.
13243 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13244 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13245 (xbm_read_bitmap_data): Change locals back to 'int', since
13246 their values must fit in 'int'.
13247 (xpm_load_image, png_load, tiff_load):
13248 Invoke x_create_x_image_and_pixmap earlier,
13249 to avoid much needless work if the image is too large.
13250 (tiff_load): Treat overly large images as if
13251 x_create_x_image_and_pixmap failed, not as malloc failures.
13252 (gs_load): Use x_check_image_size.
13254 * gtkutil.c: Omit integer casts.
13255 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13256 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13258 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13260 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13261 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13262 would wrongly return t on a 64-bit host.
13264 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13265 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13266 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13267 and therefore cause GCC to emit a bogus diagnostic in some cases.
13269 * image.c: Integer signedness and overflow and related fixes.
13270 This is not an exhaustive set of fixes, but it's time to
13271 record what I've got.
13272 (lookup_pixel_color, check_image_size): Remove redundant decls.
13273 (check_image_size): Don't assume that arbitrary EMACS_INT values
13274 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13275 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13276 (tiff_load, imagemagick_load_image):
13277 Check for overflow in size calculations.
13278 (x_create_x_image_and_pixmap): Remove unnecessary test for
13279 xmalloc returning NULL; that can't happen.
13280 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13281 (xpm_color_bucket): Use better integer hashing function.
13282 (xpm_cache_color): Don't possibly over-allocate memory.
13283 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13284 (gif_memory_source):
13285 Use ptrdiff_t, not int or size_t, to record sizes.
13286 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13287 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13288 either works, as we prefer signed integers.
13289 (tiff_read_from_memory, tiff_write_from_memory):
13290 Return tsize_t, not size_t, since that's what the TIFF API wants.
13291 (tiff_read_from_memory): Don't fail simply because the read would
13292 go past EOF; instead, return a short read.
13293 (tiff_load): Omit no-longer-needed casts.
13294 (Fimagemagick_types): Don't assume size fits into 'int'.
13296 Improve hashing quality when configured --with-wide-int.
13297 * fns.c (hash_string): New function, taken from sxhash_string.
13298 Do not discard information about ASCII character case; this
13299 discarding is no longer needed.
13300 (sxhash-string): Use it. Change sig to match it. Caller changed.
13301 * lisp.h: Declare it.
13302 * lread.c (hash_string): Remove, since we now use fns.c's version.
13303 The fns.c version returns a wider integer if --with-wide-int is
13304 specified, so this should help the quality of the hashing a bit.
13306 * emacs.c: Integer overflow minor fix.
13307 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13308 Define only if GNU_LINUX.
13309 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13311 * dispnew.c: Integer signedness and overflow fixes.
13312 Remove unnecessary forward decls, that were a maintenance hassle.
13313 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13315 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13316 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13317 (prepare_desired_row, line_draw_cost):
13318 Use int, not unsigned, where either works.
13319 (save_current_matrix, restore_current_matrix):
13320 Use ptrdiff_t, not size_t, where either works.
13321 (init_display): Check for overflow more accurately, and without
13322 relying on undefined behavior.
13324 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13325 Remove, replacing with the new symbols in lisp.h. All uses changed.
13326 * fileio.c (make_temp_name):
13327 * filelock.c (lock_file_1, lock_file):
13328 * xdisp.c (message_dolog):
13329 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13330 Use pMd etc. instead.
13331 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13332 replacing the pWIDE etc. symbols removed from editfns.c.
13334 * keyboard.h (num_input_events): Now uintmax_t.
13335 This is (very slightly) less likely to mess up due to wraparound.
13338 * buffer.c: Integer signedness fixes.
13339 (alloc_buffer_text, enlarge_buffer_text):
13340 Use ptrdiff_t rather than size_t when either will do, as we prefer
13343 * alloc.c: Integer signedness and overflow fixes.
13344 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13345 (__malloc_size_t): Default to size_t, not to int.
13346 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13347 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13348 Prefer ptrdiff_t to size_t when either would do, as we prefer
13350 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13351 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13352 Now const. Initialize with values that are in range even if char
13354 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13355 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13356 These functions do the right thing with sizes > 2**32.
13357 (check_depth): Now ptrdiff_t, not int.
13358 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13359 Adjust to new way of storing sizes. Check for size overflow bugs
13361 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13362 slightly wrong anyway, as it missed one instance of
13363 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13364 (refill_memory_reserve): Omit needless cast to size_t.
13365 (mark_object_loop_halt): Mark as externally visible.
13367 * xselect.c: Integer signedness and overflow fixes.
13368 (Fx_register_dnd_atom, x_handle_dnd_message):
13369 Use ptrdiff_t, not size_t, since we prefer signed.
13370 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13371 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13372 x_dnd_atoms_size and x_dnd_atoms_length.
13374 * doprnt.c: Prefer signed to unsigned when either works.
13376 * doprnt.c (doprnt):
13378 * xdisp.c (vmessage):
13379 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13380 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13381 prefer signed arithmetic to avoid comparison confusion.
13382 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13383 but is a bit tricky.
13385 Assume freestanding C89 headers, string.h, stdlib.h.
13386 * data.c, doprnt.c, floatfns.c, print.c:
13387 Include float.h unconditionally.
13388 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13389 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13390 * regex.c: Likewise for stddef.h, string.h.
13391 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13392 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13393 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13394 (STDC_HEADERS): Remove obsolete defines.
13395 * sysdep.c: Include limits.h unconditionally.
13397 Assume support for memcmp, memcpy, memmove, memset.
13398 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13399 * regex.c (memcmp, memcpy):
13400 Remove; we assume C89 now.
13402 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13403 (__malloc_safe_bcopy): Remove; no longer needed.
13405 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13406 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13407 well either way, and we prefer signed to unsigned.
13409 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13411 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13412 closes the connection while we're reading (bug#9182).
13414 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13416 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13417 are specified (Bug#9168).
13419 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13421 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13422 Found by GCC static checking and --with-wide-int on a 32-bit host.
13424 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13426 * xdisp.c (compute_display_string_pos): Fix logic of caching
13427 previous display string position. Initialize cached_prev_pos to
13428 -1. Fixes slow-down at the beginning of a buffer.
13430 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13432 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13433 for attrs[LFACE_FONTSET_INDEX].
13435 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13437 * xml.c (parse_region): Remove unused local
13438 that was recently introduced.
13440 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13442 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13443 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13445 * xdisp.c (move_it_in_display_line_to): Record the best matching
13446 position for TO_CHARPOS while scanning the line, and restore it on
13447 exit if none of the characters scanned was an exact match.
13448 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13449 when exact match is impossible due to invisible text, and the
13450 lines are truncated.
13452 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13454 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13457 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13459 Fix a significant slow-down of cursor motion with C-n, C-p,
13460 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13461 auto-repeat under bidi redisplay in fontified buffers.
13462 * xdisp.c (compute_stop_pos_backwards): New function.
13463 (next_element_from_buffer): Call compute_stop_pos_backwards to
13464 find a suitable prev_stop when we find ourselves before
13466 (reseat): Don't look for prev_stop, as that could mean a very long
13468 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13469 <cached_disp_overlay_modiff>: Cache for last found display string
13471 (compute_display_string_pos): Return the cached position if asked
13472 about the same buffer in the same area of character positions, and
13473 the buffer wasn't changed since the time the display string
13474 position was cached.
13476 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13478 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13479 is an integer, which is important for empty lines. (Bug#9149)
13481 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13483 * frame.c (Fmodify_frame_parameters): In tty case, update the
13484 default face if necessary (Bug#4238).
13486 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13488 * editfns.c (Fstring_to_char): No need to explain what a character
13489 is in the docstring (Bug#6576).
13491 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13493 * xml.c (parse_region): Make sure we always return a tree.
13495 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13497 * xml.c (parse_region): If a document contains only comments,
13500 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13502 * xml.c (make_dom): Return comments, too.
13504 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13507 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13508 and the surrounding thread.
13509 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13510 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13511 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13513 * s/openbsd.h (BROKEN_SIGIO): Define.
13514 * unexelf.c (unexec) [__OpenBSD__]:
13515 Don't update the .mdebug section of the Alpha COFF symbol table.
13517 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13519 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13522 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13524 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13525 This fixes some race conditions on the permissions of any newly
13528 * alloc.c (valid_pointer_p): Use pipe, not open.
13529 This fixes some permissions issues when debugging.
13531 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13532 If fchown fails to set both uid and gid, try to set just gid,
13533 as that is sometimes allowed. Adjust the file's mode to eliminate
13534 setuid or setgid bits that are inappropriate if fchown fails.
13536 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13538 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13539 to compare Lisp_Objects.

13544 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13546 * lread.c (read_integer): Unread even EOF character.
13547 (read1): Likewise. Properly record start position of symbol.

13550 symbol character follows.
13552 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13554 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13555 This works around a problem with the previous change to Fcopy_file.
13556 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13557 and without this change, GCC might complain about discarding
13558 fchown's return value.
13560 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13562 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13564 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13566 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13568 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13570 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13571 it's used from the C level.
13573 * process.c: Use the same condition for POLL_FOR_INPUT in both
13574 keyboard.c and process.c (bug#1858).
13576 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13578 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13579 (Fgnutls_boot): Use it.
13581 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13583 * doc.c (Fsubstitute_command_keys): Revert last change.
13585 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13587 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13588 quotes the next character, and doesn't affect other longer
13589 sequences (bug#8935).
13591 * lread.c (syms_of_lread): Clarify that is isn't only
13592 `eval-buffer' and `eval-defun' that's affected by
13593 `lexical-binding' (bug#8460).
13595 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13597 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13598 bidi redisplay when a line includes both an image and is truncated.
13600 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13602 Fix minor problems found by static checking.
13603 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13604 (elsz): Now a signed constant, not a size_t var. We prefer signed
13605 types to unsigned, to avoid integer comparison confusion. Without
13606 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13607 "cannot optimize loop, the loop counter may overflow", a symptom
13609 * indent.c (Fvertical_motion): Mark locals as initialized.
13610 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13612 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13614 * search.c (Fre_search_backward): Mention `case-fold-search' in
13615 all the re_search_* functions (bug#8138).

13635 buffer position was specified. Initialize paragraph_embedding to
13637 (reseat_to_string): Initialize the bidi iterator.
13638 (display_string): If we need to ignore text properties of
13639 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13640 original value of -1 will not work with bidi.)
13641 (compute_display_string_pos): First arg is now struct
13642 `text_pos *'; all callers changed. Support display properties on
13644 (compute_display_string_end): Support display properties on Lisp
13646 (init_iterator, reseat_1, reseat_to_string): Initialize the
13647 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13648 when iterating on a string not from display properties).
13649 (compute_display_string_pos, compute_display_string_end):
13650 Fix calculation of the object to scan. Fixes an error when using
13652 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13653 base_level_stop; instead, set base_level_stop to BEGV.
13654 Fixes crashes in vertical-motion.
13655 (next_element_from_buffer): Improve commentary for when
13656 the iterator is before prev_stop.
13657 (init_iterator): Initialize bidi_p from the default value of
13658 bidi-display-reordering, not from buffer-local value. Use the
13659 buffer-local value only if initializing for buffer iteration.
13660 (handle_invisible_prop): Support invisible properties on strings
13661 that are being bidi-reordered.

13680 parts of next_element_from_buffer, next_element_from_string, and
13681 next_element_from_c_string.
13682 (tool_bar_lines_needed, redisplay_tool_bar)
13683 (display_menu_bar): Force left-to-right direction. Add a FIXME
13684 comment for making that be controlled by a user option.

13693 (get_overlay_strings_1, push_display_prop): Set up the bidi
13694 iterator for displaying display or overlay strings.
13695 (forward_to_next_line_start): Don't use the shortcut if
13697 (back_to_previous_visible_line_start): If handle_display_prop
13698 pushed the iterator stack, restore the internal state of the bidi
13699 iterator by calling bidi_pop_it same number of times.
13700 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
13701 and we are bidi-iterating, don't decrement the iterator position;
13702 instead, set the first_elt flag in the bidi iterator, to produce
13704 (reseat_1): Remove redundant setting of string_from_display_prop_p.
13705 (push_display_prop): xassert that we are iterating a buffer.
13706 (push_it, pop_it): Save and restore paragraph_embedding member.
13707 (handle_single_display_spec, next_overlay_string)
13708 (get_overlay_strings_1, reseat_1, reseat_to_string)
13709 (push_display_prop): Set up the `unibyte' member of bidi_it.string
13710 correctly. Don't assume unibyte strings are not bidi-reordered.
13711 (compute_display_string_pos)
13712 (compute_display_string_end): Fix handling the case of C string.

13718 popping after iteration over a string that came from a display
13719 property. Fix a typo in popping stretch info. Add an assertion
13720 for verifying that the iterator position is in sync with the bidi
13722 (handle_single_display_spec, get_overlay_strings_1)

13736 (try_scrolling, redisplay_window, display_line): Use them when
13737 saving a temporary copy of the iterator and restoring it back.
13738 (back_to_previous_visible_line_start, reseat_1)

13747 displayed in margins. (Bug#8133) (Bug#8867)
13748 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
13750 (pos_visible_p): Support positions in bidi-reordered lines.
13751 Save and restore bidi cache.
13753 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

13776 changed to -1 and -2, respectively.
13777 (bidi_char_at_pos): New function.
13778 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

13811 (bidi_push_it, bidi_pop_it): Add prototypes.
13812 (struct iterator_stack_entry): New members bidi_p,
13813 paragraph_embedding, and from_disp_prop_p.

13861 Pass Qx_lost_selection_functions rather than
13862 Vx_lost_selection_functions to Frun_hook_with_args.
13864 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
13866 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
13867 The old code sometimes used this field without initializing it.
13869 * alloc.c (gc_sweep): Don't read past end of array.
13870 In theory, the old code could also have corrupted Emacs internals,
13871 though it'd be very unlikely.
13873 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
13875 * character.c (Fcharacterp): Don't advertise optional ignored
13876 argument. (Bug#4026)

14138 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

14176 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14177 subseconds part to the entropy, as that's a bit more random.
14178 Prefer signed to unsigned, since the signedness doesn't matter and
14179 in general we prefer signed. When given a limit, use a
14180 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14181 latter isn't right if USE_2_TAGS_FOR_INTS.
14182 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14183 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14195 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14196 This is more efficient than Ffile_directory_p and avoids a minor race.

14200 * buffer.c (Foverlay_put): Say what the return value is

14207 error be more correct.
14209 * fns.c (Frequire): Remove the mention of the .gz files, since

14226 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

14328 * eval.c (struct backtrace): Simplify and port the data structure.
14329 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14330 signed bit field, as this assumption is not portable and it makes
14331 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14332 "char debug_on_exit : 1" as this is not portable either; instead,
14333 use the portable "unsigned int debug_on_exit : 1". Remove unused
14334 member evalargs. Remove obsolete comments about cc bombing out.
14336 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

14404 (emacs_fixed_new): Set priv->f to argument.
14405 (emacs_fixed_get_preferred_width)
14406 (emacs_fixed_get_preferred_height): Use min_width/height from
14407 frames size_hint to set minimum and natural (Bug#8919).
14408 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
14409 and use min_width/height from frames size_hint to set
14410 min_width/height (Bug#8919).
14412 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

14430 Use gnulib's dup2 module instead of rolling our own.
14431 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.
14433 2011-06-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14435 * dispnew.c (scrolling_window): Before scrolling, turn off a

14498 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
14500 Integer and buffer overflow fixes (Bug#8873).
14502 * print.c (printchar, strout): Check for string overflow.
14503 (PRINTPREPARE, printchar, strout):
14504 Don't set size unless allocation succeeds.
14506 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14507 for sizes. Check for string overflow more accurately.
14508 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
14510 * macros.c: Integer and buffer overflow fixes.
14511 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14512 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
14513 Use ptrdiff_t, not int, for sizes.

14515 Check for size-calculation overflow.
14516 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
14518 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14520 * lread.c: Integer overflow fixes.
14521 (read_integer): Radix is now EMACS_INT, not int,
14522 to improve quality of diagnostics for out-of-range radices.
14523 Calculate buffer size correctly for out-of-range radices.
14524 (read1): Check for integer overflow in radices, and in
14525 read-circle numbers.
14526 (read_escape): Avoid int overflow.
14527 (Fload, openp, read_buffer_size, read1)
14528 (substitute_object_recurse, read_vector, read_list, map_obarray):
14529 Use ptrdiff_t, not int, for sizes.

14544 2011-06-22 Leo Liu <sdl.web@gmail.com>
14546 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14547 Move to minibuffer.el.
14549 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14551 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14552 The following patches are for when GLYPH_DEBUG && !XASSERT.
14553 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14554 * dispnew.c (flush_stdout):
14555 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14556 Mark as externally visible.
14557 * dispnew.c (check_window_matrix_pointers): Now static.
14558 * dispnew.c (window_to_frame_vpos):
14559 * xfns.c (unwind_create_frame):
14560 * xterm.c (x_check_font): Remove unused local.
14561 * scroll.c (CHECK_BOUNDS):
14562 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14563 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14564 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14565 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14566 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14568 (debug_method_add): Use va_list and vsprintf rather than relying
14569 on undefined behavior with wrong number of arguments.
14570 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14571 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14572 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14573 since we're not interested in debugging glyphs with old libraries.
14574 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14575 GCC 4.6.0's static checking.
14577 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14579 Integer overflow and signedness fixes (Bug#8873).

14589 (x_create_bitmap_from_xpm_data):
14590 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
14591 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
14593 * xfaces.c (load_pixmap):
14594 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
14595 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14596 (.bitmaps_last, struct x_output.icon_bitmap):
14597 Use ptrdiff_t, not int, for bitmap indexes.
14598 (x_allocate_bitmap_record): Check for size overflow.
14599 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14601 Use ptrdiff_t, not int, for overlay counts.
14602 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14603 * editfns.c (overlays_around, get_pos_property):
14604 * textprop.c (get_char_property_and_overlay):
14605 * xdisp.c (next_overlay_change, note_mouse_highlight):
14606 * xfaces.c (face_at_buffer_position):
14607 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14608 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14609 (Fnext_overlay_change, Fprevious_overlay_change)
14610 (mouse_face_overlay_overlaps, Foverlays_in):
14611 Use ptrdiff_t, not int, for sizes.
14612 (overlays_at, overlays_in): Check for size-calculation overflow.
14614 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14616 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14617 (x_session_initialize): Do not assume string length fits in int.
14619 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14620 This is unlikely, but can occur if DPI is outlandish.
14622 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14623 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14625 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14626 * xrdb.c (magic_file_p, search_magic_path):
14627 Omit last arg SUFFIX; it was always 0. All callers changed.
14628 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14630 * xfont.c (xfont_match): Avoid need for strlen.
14632 * xfns.c: Don't assume strlen fits in int.

14635 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14636 not unsigned long, as we prefer signed integers. All callers changed.
14637 Detect integer overflow in repeat count.
14638 (message_dolog): Don't assume print length fits in 39 bytes.
14639 (display_mode_element): Don't assume strlen fits in int.
14641 * termcap.c: Don't assume sizes fit in int and never overflow.
14642 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14643 (gobble_line): Check for size-calculation overflow.
14645 * minibuf.c (Fread_buffer):
14646 * lread.c (intern, intern_c_string):
14647 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
14648 Don't assume string length fits in int.

14657 Don't assume integer property fits in fixnum.
14658 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14660 * filelock.c: Fix some buffer overrun and integer overflow issues.
14661 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14662 Reformulate so as not to need the command string.
14663 Invoke gzip -cd rather than gunzip, as it's more portable.
14664 (lock_info_type, lock_file_1, lock_file):
14665 Don't assume pid_t and time_t fit in unsigned long.
14666 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14667 (current_lock_owner): Prefer signed type for sizes.
14668 Use memcpy, not strncpy, where memcpy is what is really wanted.
14669 Don't assume (via atoi) that time_t and pid_t fit in int.
14670 Check for time_t and/or pid_t out of range, e.g., via a network share.
14671 Don't alloca where an auto var works fine.
14673 * fileio.c: Fix some integer overflow issues.
14674 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14675 Don't assume string length fits in int.
14676 (directory_file_name): Don't assume string length fits in long.
14677 (make_temp_name): Don't assume pid fits in int, or that its print
14678 length is less than 20.
14680 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14682 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14684 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14686 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14687 We prefer signed integers, even for size calculations.
14689 * emacs.c: Don't assume string length fits in 'int'.
14690 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14691 (main): Don't invoke strlen when not needed.

14696 * callproc.c (getenv_internal_1, getenv_internal)
14697 (Fgetenv_internal):
14698 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14700 * lread.c (invalid_syntax): Omit length argument.
14701 All uses changed. This doesn't fix a bug, but it simplifies the
14702 code away from its former Hollerith-constant appearance, and it's
14703 one less 'int' to worry about when looking at integer-overflow issues.
14704 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14706 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14707 This didn't break anything, but it didn't help either.
14708 It's confusing to put a bogus integer in a place where the actual
14709 value does not matter.
14710 (LIST_END_P): Remove unused macro and its bogus comment.
14711 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14713 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14714 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14716 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14717 We prefer signed types, and the value cannot exceed the EMACS_INT
14718 range anyway (because otherwise the length would not be representable).
14719 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14720 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14721 This avoids a GCC warning when WIDE_EMACS_INT.
14723 * indent.c (sane_tab_width): New function.
14724 (current_column, scan_for_column, Findent_to, position_indentation)
14725 (compute_motion): Use it. This is just for clarity.
14726 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14728 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14730 * lisp.h (lint_assume): New macro.
14731 * composite.c (composition_gstring_put_cache):
14732 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14734 * editfns.c, insdel.c:
14735 Omit unnecessary forward decls, to simplify future changes.
14737 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
14739 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
14741 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
14742 Use much-faster test for byte-length change.
14743 Don't assume string byte-length fits in 'int'.
14744 Check that character arg fits in 'int'.
14745 (mapcar1): Declare byte as byte, for clarity.
14747 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
14749 * fns.c (concat): Catch string overflow earlier.
14750 Do not rely on integer wraparound.
14752 * dispextern.h (struct it.overlay_strings_charpos)
14753 (struct it.selective): Now EMACS_INT, not int.
14754 * xdisp.c (forward_to_next_line_start)
14755 (back_to_previous_visible_line_start)
14756 (reseat_at_next_visible_line_start, next_element_from_buffer):
14757 Don't arbitrarily truncate the value of 'selective' to int.
14759 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
14761 * composite.c: Don't truncate sizes to 'int'.
14762 (composition_gstring_p, composition_reseat_it)
14763 (composition_adjust_point): Use EMACS_INT, not int.
14764 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
14765 not EMACS_UINT, for indexes.
14767 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
14769 * buffer.c: Include <verify.h>.
14770 (struct sortvec.priority, struct sortstr.priority):
14771 Now EMACS_INT, not int.
14772 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
14773 (struct sortstr.size, record_overlay_string)
14774 (struct sortstrlist.size, struct sortlist.used):
14775 Don't truncate size to int.
14776 (record_overlay_string): Check for size-calculation overflow.
14777 (init_buffer_once): Check at compile-time, not run-time.
14779 2011-06-22 Jim Meyering <meyering@redhat.com>
14781 Don't leak an XBM-image-sized buffer
14782 * image.c (xbm_load): Free the image buffer after using it.
14784 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
14787 * composite.c (find_automatic_composition): Omit needless 'return 0;'
14788 that Sun C diagnosed.
14789 * fns.c (secure_hash): Fix pointer signedness issue.
14790 * intervals.c (static_offset_intervals): New function.
14791 (offset_intervals): Use it.
14793 2011-06-21 Leo Liu <sdl.web@gmail.com>
14796 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
14799 * fns.c (secure_hash): Rename from crypto_hash_function and change
14800 the first arg to accept symbols.
14801 (Fsecure_hash): New primitive.
14802 (syms_of_fns): New symbols.
14804 2011-06-20 Deniz Dogan <deniz@dogan.se>
14806 * process.c (Fset_process_buffer): Clarify return value in
14809 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
14811 * dispnew.c (add_window_display_history): Use BVAR.
14813 * xdisp.c (debug_method_add): Use BVAR.
14814 (check_window_end, dump_glyph_matrix, dump_glyph)
14815 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
14817 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
14820 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
14821 check till after the cache is created in init_frame_faces.
14823 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
14825 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
14827 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
14829 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
14830 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
14831 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
14833 Improve buffer-overflow checking (Bug#8873).
14834 * fileio.c (Finsert_file_contents):
14835 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
14836 Remove the old (too-loose) buffer overflow checks.
14837 They weren't needed, since make_gap checks for buffer overflow.
14838 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
14839 The old code merely checked for Emacs fixnum overflow, and relied
14840 on undefined (wraparound) behavior. The new code avoids undefined
14841 behavior, and also checks for ptrdiff_t and/or size_t overflow.
14843 * editfns.c (Finsert_char): Don't dump core with very negative counts.
14844 Tune. Don't use wider integers than needed. Don't use alloca.
14845 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
14847 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
14849 * insdel.c, lisp.h (buffer_overflow): New function.
14850 (insert_from_buffer_1, replace_range, replace_range_2):
14851 * insdel.c (make_gap_larger):
14852 * editfns.c (Finsert_char):
14853 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
14855 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
14857 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
14859 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
14861 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
14862 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
14864 * fileio.c: Don't assume EMACS_INT fits in off_t.
14865 (emacs_lseek): New static function.
14866 (Finsert_file_contents, Fwrite_region): Use it.
14867 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
14869 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
14871 * fns.c: Don't overflow int when computing a list length.
14872 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
14873 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
14874 truncation on 64-bit hosts. Check for QUIT every
14875 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
14876 faster and is responsive enough.
14877 (Flength): Report an error instead of overflowing an integer.
14878 (Fsafe_length): Return a float if the value is not representable
14879 as a fixnum. This shouldn't happen except in contrived situations.
14880 (Fnthcdr, Fsort): Don't assume list length fits in int.
14881 (Fcopy_sequence): Don't assume vector length fits in int.
14883 * alloc.c: Check that resized vectors' lengths fit in fixnums.
14884 (header_size, word_size): New constants.
14885 (allocate_vectorlike): Don't check size overflow here.
14886 (allocate_vector): Check it here instead, since this is the only
14887 caller of allocate_vectorlike that could cause overflow.
14888 Check that the new vector's length is representable as a fixnum.
14890 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
14891 The previous code was bogus. For example, next_almost_prime (32)
14892 returned 39, which is undesirable as it is a multiple of 3; and
14893 next_almost_prime (24) returned 25, which is a multiple of 5 so
14894 why was the code bothering to check for multiples of 7?
14896 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
14898 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
14900 Variadic C functions now count arguments with ptrdiff_t.
14901 This partly undoes my 2011-03-30 change, which replaced int with size_t.
14902 Back then I didn't know that the Emacs coding style prefers signed int.
14903 Also, in the meantime I found a few more instances where arguments
14904 were being counted with int, which may truncate counts on 64-bit
14905 machines, or EMACS_INT, which may be unnecessarily wide.
14906 * lisp.h (struct Lisp_Subr.function.aMANY)
14907 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
14908 Arg counts are now ptrdiff_t, not size_t.
14909 All variadic functions and their callers changed accordingly.
14910 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
14911 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
14912 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
14913 * callint.c (Fcall_interactively): Check arg count for overflow,
14914 to avoid potential buffer overrun. Use signed char, not 'int',
14915 for 'varies' array, so that we needn't bother to check its size
14916 calculation for overflow.
14917 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
14918 * eval.c (apply_lambda):
14919 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
14920 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
14921 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
14923 * callint.c (Fcall_interactively): Don't use index var as event count.
14925 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
14926 * mem-limits.h (SIZE): Remove; no longer used.
14928 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
14930 Remove unnecessary casts.
14931 * xterm.c (x_term_init):
14932 * xfns.c (x_set_border_pixel):
14933 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
14934 These aren't needed now that we assume ANSI C.
14936 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
14937 It's more likely to cause problems (due to unsigned overflow)
14940 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
14942 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
14944 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
14946 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
14948 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
14950 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
14952 GLYPH_CODE_FACE returns EMACS_INT, not int.
14953 * dispextern.h (merge_faces):
14954 * xfaces.c (merge_faces):
14955 * xdisp.c (get_next_display_element, next_element_from_display_vector):
14956 Don't assume EMACS_INT fits in int.
14958 * character.h (CHAR_VALID_P): Remove unused parameter.
14959 * fontset.c, lisp.h, xdisp.c: All uses changed.
14961 * editfns.c (Ftranslate_region_internal): Omit redundant test.
14963 * fns.c (concat): Minor tuning based on overflow analysis.
14964 This doesn't fix any bugs. Use int to hold character, instead
14965 of constantly refetching from Emacs object. Use XFASTINT, not
14966 XINT, for value known to be a character. Don't bother comparing
14967 a single byte to 0400, as it's always less.
14969 * floatfns.c (Fexpt):
14970 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
14972 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
14975 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
14977 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
14978 Without this fix, on a 64-bit host (aset S 0 4294967386) would
14979 incorrectly succeed when S was a string, because 4294967386 was
14980 truncated before it was used.
14982 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
14983 Otherwise, an out-of-range integer could cause undefined behavior
14986 * composite.c: Use int, not EMACS_INT, for characters.
14987 (fill_gstring_body, composition_compute_stop_pos): Use int, not
14988 EMACS_INT, for values that are known to be in character range.
14989 This doesn't fix any bugs but is the usual style inside Emacs and
14990 may generate better code on 32-bit machines.
14992 Make sure a 64-bit char is never passed to ENCODE_CHAR.
14993 This is for reasons similar to the recent CHAR_STRING fix.
14994 * charset.c (Fencode_char): Check that character arg is actually
14995 a character. Pass an int to ENCODE_CHAR.
14996 * charset.h (ENCODE_CHAR): Verify that the character argument is no
14997 wider than 'int', as a compile-time check to prevent future regressions
15000 * character.c (char_string): Remove unnecessary casts.
15002 Make sure a 64-bit char is never passed to CHAR_STRING.
15003 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15004 by silently ignoring the top 32 bits, allowing some values
15005 that were far too large to be valid characters.
15006 * character.h: Include <verify.h>.
15007 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15008 arguments are no wider than unsigned, as a compile-time check
15009 to prevent future regressions in this area.
15011 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15012 (Fsubst_char_in_region):
15014 * xdisp.c (decode_mode_spec_coding):
15015 Adjust to CHAR_STRING's new requirement.
15016 * editfns.c (Finsert_char, Fsubst_char_in_region):
15017 * fns.c (concat): Check that character args are actually
15018 characters. Without this test, these functions did the wrong
15019 thing with wildly out-of-range values on 64-bit hosts.
15021 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15022 These casts should not be needed on 32-bit hosts, either.
15023 * keyboard.c (read_char):
15024 * lread.c (Fload): Remove casts to unsigned.
15026 * lisp.h (UNSIGNED_CMP): New macro.
15027 This fixes comparison bugs on 64-bit hosts.
15028 (ASCII_CHAR_P): Use it.
15029 * casefiddle.c (casify_object):
15030 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15031 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15032 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15033 * dispextern.h (FACE_FROM_ID):
15034 * keyboard.c (read_char): Use UNSIGNED_CMP.
15036 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15037 not to EMACS_INT, to avoid GCC warning.
15039 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15041 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15042 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15043 isn't needed on 32-bit machines.
15045 * buffer.c (Fgenerate_new_buffer_name):
15046 Use EMACS_INT for count, not int.
15047 (advance_to_char_boundary): Return EMACS_INT, not int.
15049 * data.c (Qcompiled_function): Now static.
15051 * window.c (window_body_lines): Now static.
15053 * image.c (gif_load): Rename local to avoid shadowing.
15055 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15056 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15057 * alloc.c (make_save_value): Integer argument is now of type
15058 ptrdiff_t, not int.
15059 (mark_object): Use ptrdiff_t, not int.
15060 * lisp.h (pD): New macro.
15061 * print.c (print_object): Use it.
15063 * alloc.c: Use EMACS_INT, not int, to count objects.
15064 (total_conses, total_markers, total_symbols, total_vector_size)
15065 (total_free_conses, total_free_markers, total_free_symbols)
15066 (total_free_floats, total_floats, total_free_intervals)
15067 (total_intervals, total_strings, total_free_strings):
15068 Now EMACS_INT, not int. All uses changed.
15069 (Fgarbage_collect): Compute overall total using a double, so that
15070 integer overflow is less likely to be a problem. Check for overflow
15071 when converting back to an integer.
15072 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15073 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15074 These were 'int' variables that could overflow on 64-bit hosts;
15075 they were never used, so remove them instead of repairing them.
15076 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15077 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15078 Previously, this ceilinged at INT_MAX, but that doesn't work on
15080 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15082 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15083 (allocate_vectorlike): Check for ptrdiff_t overflow.
15084 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15085 when a (possibly-narrower) signed value would do just as well.
15086 We prefer using signed arithmetic, to avoid comparison confusion.
15088 * alloc.c: Catch some string size overflows that we were missing.
15089 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15090 for convenience in STRING_BYTES_MAX.
15091 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15092 The definition here is exact; the one in lisp.h was approximate.
15093 (allocate_string_data): Check for string overflow. This catches
15094 some instances we weren't catching before. Also, it catches
15095 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15096 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15097 and ptrdiff_t and EMACS_INT are both 64 bits.
15099 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15100 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15101 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15103 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15105 * alloc.c (Fmake_string): Check for out-of-range init.
15107 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15109 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15111 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15113 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15114 xg_get_default_scrollbar_width.
15116 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
15117 (int_gtk_range_get_value): Move to the scroll bar part of the file.
15118 (style_changed_cb): Call update_theme_scrollbar_width and call
15119 x_set_scroll_bar_default_width and xg_frame_set_char_size for
15120 all frames (Bug#8505).
15121 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
15122 Call gtk_window_set_resizable if HAVE_GTK3.
15123 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
15124 and height if HAVE_GTK3 (Bug#8505).
15125 (scroll_bar_width_for_theme): New variable.
15126 (update_theme_scrollbar_width): New function.
15127 (xg_get_default_scrollbar_width): Move code to
15128 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
15129 (xg_initialize): Call update_theme_scrollbar_width.
15131 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
15133 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
15135 2011-06-12 Martin Rudalics <rudalics@gmx.at>
15137 * frame.c (make_frame): Call other_buffer_safely instead of
15140 * window.c (temp_output_buffer_show): Call display_buffer with
15141 second argument Vtemp_buffer_show_specifiers and reset latter
15142 immediately after the call.
15143 (Vtemp_buffer_show_specifiers): New variable.
15144 (auto_window_vscroll_p, next_screen_context_lines)
15145 (Vscroll_preserve_screen_position): Remove leading asterisks from
15148 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
15150 Fix minor problems found by GCC 4.6.0 static checking.
15151 * buffer.c (Qclone_number): Remove for now, as it's unused.
15152 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
15153 (record_buffer): Remove unused local.
15154 * frame.c (other_visible_frames, frame_buffer_list): Now static.
15155 (set_frame_buffer_list): Remove; unused.
15156 * frame.h (other_visible_frames): Remove decl.
15157 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
15158 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
15159 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
15161 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
15162 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
15163 Define only if HAVE_GPM.
15164 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
15165 (update_hints_inhibit): Remove; never set. All uses removed.
15166 * widgetprv.h (emacsFrameClassRec): Remove decl.
15167 * window.c (delete_deletable_window): Now returns void, since it
15168 wasn't returning anything.
15169 (compare_window_configurations): Remove unused locals.
15170 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
15171 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
15172 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
15173 the same widths as pointers. This follows up on the 2011-05-06 patch.
15174 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
15175 * xterm.h: Likewise.
15176 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
15178 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
15180 * makefile.w32-in: Update dependencies.
15181 (LISP_H): Add lib/intprops.h.
15183 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
15185 * image.c (gif_load): Add animation frame delay to the metadata.
15186 (syms_of_image): Use DEFSYM. New symbol `delay'.
15188 2011-06-11 Martin Rudalics <rudalics@gmx.at>
15190 * window.c (delete_deletable_window): Re-add.
15191 (Fset_window_configuration): Rewrite to handle dead buffers and
15192 consequently deletable windows.
15193 (window_tree, Fwindow_tree): Remove. Supply functionality in

15648 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
15650 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15652 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
15653 in the current matrix if keep_current_p is non-zero.
15655 2011-06-04 Eli Zaretskii <eliz@gnu.org>
15657 * bidi.c (bidi_level_of_next_char): Fix last change.
15659 2011-06-03 Eli Zaretskii <eliz@gnu.org>
15661 Support bidi reordering of text covered by display properties.
15663 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
15664 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
15665 (bidi_cache_search, bidi_cache_iterator_state)
15666 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
15667 (bidi_level_of_next_char, bidi_move_to_visually_next):
15668 Support character positions inside a run of characters covered by a
15670 (bidi_paragraph_init, bidi_resolve_explicit_1)
15671 (bidi_level_of_next_char): Call bidi_fetch_char and
15672 bidi_fetch_char_advance instead of FETCH_CHAR and
15673 FETCH_CHAR_ADVANCE.
15674 (bidi_init_it): Initialize new members.
15675 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
15677 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
15678 instead of using explicit *_CHAR codes.
15679 (bidi_resolve_explicit, bidi_resolve_weak):
15680 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
15681 bidirectional text is supported only in multibyte buffers.
15682 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
15683 it to initialize the frame_window_p member of struct bidi_it.
15684 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
15685 (bidi_resolve_explicit, bidi_resolve_weak)
15686 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
15687 bidi_it->nchars is non-positive.
15688 (bidi_level_of_next_char): Don't try to lookup the cache for the
15689 next/previous character if nothing is cached there yet, or if we
15690 were just reseat()'ed to a new position.
15692 * xdisp.c (set_cursor_from_row): Set start and stop points
15693 according to the row's direction when priming the loop that looks
15694 for the glyph on which to display cursor.
15695 (single_display_spec_intangible_p): Function deleted.
15696 (display_prop_intangible_p): Reimplement to call
15697 handle_display_spec instead of single_display_spec_intangible_p.
15698 Accept 3 additional arguments needed by handle_display_spec.
15699 This fixes incorrect cursor motion across display property with complex
15700 values: lists, `(when COND...)' forms, etc.
15701 (single_display_spec_string_p): Support property values that are
15702 lists with the argument STRING its top-level element.
15703 (display_prop_string_p): Fix the condition for processing a
15704 property that is a list to be consistent with handle_display_spec.
15705 (handle_display_spec): New function, refactored from the
15706 last portion of handle_display_prop.
15707 (compute_display_string_pos): Accept additional argument
15708 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
15709 value of a `display' property is a "replacing spec".
15710 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
15711 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
15712 the display property, but just return a value indicating whether
15713 the display property will replace the characters it covers.
15714 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
15715 frame_window_p members of struct bidi_it.
15716 (compute_display_string_pos, compute_display_string_end):
15718 (push_it): Accept second argument POSITION, where pop_it should
15719 jump to continue iteration.
15720 (reseat_1): Initialize bidi_it.disp_pos.
15722 * keyboard.c (adjust_point_for_property): Adjust the call to
15723 display_prop_intangible_p to its new signature.
15725 * dispextern.h (struct bidi_it): New member frame_window_p.
15726 (bidi_init_it): Update prototypes.
15727 (display_prop_intangible_p): Update prototype.
15728 (compute_display_string_pos, compute_display_string_end):
15729 Declare prototypes.
15730 (struct bidi_it): New members nchars and disp_pos. ch_len is now
15733 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
15735 Malloc failure behavior now depends on size of allocation.
15736 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
15737 * lisp.h: Change signatures accordingly.
15738 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
15739 All callers changed. (Bug#8762)
15741 * gnutls.c: Use Emacs's memory allocators.
15742 Without this change, the gnutls library would invoke malloc etc.
15743 directly, which causes problems on non-SYNC_INPUT hosts, and which
15744 runs afoul of improving memory_full behavior. (Bug#8761)
15745 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
15746 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
15747 xfree instead of the default malloc, realloc, free.
15748 (Fgnutls_boot): No need to check for memory allocation failure,
15749 since xmalloc does that for us.
15751 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
15752 * category.c (hash_get_category_set):
15753 * ccl.c (ccl_driver):
15754 * charset.c (Fdefine_charset_internal):
15755 * charset.h (struct charset.hash_index):
15756 * composite.c (get_composition_id, gstring_lookup_cache)
15757 (composition_gstring_put_cache):
15758 * composite.h (struct composition.hash_index):
15759 * dispextern.h (struct image.hash):

15761 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
15762 (hashfn_equal, hashfn_user_defined, make_hash_table)
15763 (maybe_resize_hash_table, hash_lookup, hash_put)
15764 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
15765 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
15766 (Fsxhash, Fgethash, Fputhash, Fmaphash):
15767 * image.c (make_image, search_image_cache, lookup_image)
15768 (xpm_put_color_table_h):
15769 * lisp.h (struct Lisp_Hash_Table):
15770 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
15771 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
15772 for hashes and hash indexes, instead of 'unsigned' and 'int'.
15773 * alloc.c (allocate_vectorlike):
15774 Check for overflow in vector size calculations.
15775 * ccl.c (ccl_driver):
15776 Check for overflow when converting EMACS_INT to int.
15777 * fns.c, image.c: Remove unnecessary static decls that would otherwise
15778 need to be updated by these changes.
15779 * fns.c (make_hash_table, maybe_resize_hash_table):
15780 Check for integer overflow with large hash tables.
15781 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
15782 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
15783 (SXHASH_REDUCE): New macro.
15784 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
15785 Use it instead of discarding useful hash info with large hash values.
15786 (sxhash_float): New function.
15787 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
15788 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
15789 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
15790 Rewrite to use FIXNUM_BITS, as this simplifies things.
15791 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
15792 Adjust signatures to match updated version of code.
15793 (consing_since_gc): Now EMACS_INT, since a single hash table can
15794 use more than INT_MAX bytes.
15796 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
15798 Make it possible to build with GCC-4.6+ -O2 -flto.
15800 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
15802 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
15804 * minibuf.c (get_minibuffer, read_minibuf_unwind):
15805 Call minibuffer-inactive-mode.
15807 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
15809 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
15810 Update dependencies.
15812 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15814 * data.c (init_data): Remove code for UTS, this system is not
15817 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15819 Don't force ./temacs to start in terminal mode.
15821 * frame.c (make_initial_frame): Initialize faces in all cases, not
15822 only when CANNOT_DUMP is defined.
15823 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
15825 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15827 * dispnew.c (add_window_display_history): Use const for the string
15828 pointer. Remove declaration, not needed.
15830 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15832 Use 'inline', not 'INLINE'.
15833 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
15834 * alloc.c, fontset.c (INLINE): Remove.
15835 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
15836 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
15837 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
15838 * gmalloc.c (register_heapinfo): Use inline unconditionally.
15839 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
15841 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
15843 Make it possible to run ./temacs.
15845 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
15846 syms_of_callproc does the same thing. Remove test for
15847 "initialized", do it in the caller.
15848 * emacs.c (main): Avoid calling set_initial_environment when dumping.
15850 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
15852 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
15853 (read_minibuf): Use get_minibuffer.
15854 (syms_of_minibuf): Use DEFSYM.
15855 (Qmetadata): New var.
15856 * data.c (Qbuffer): Don't make it static.
15857 (syms_of_data): Use DEFSYM.
15859 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
15861 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
15862 (CCL_CODE_MIN): New macro.
15864 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
15866 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
15868 * eval.c (Qdebug): Now static.
15869 * lisp.h (Qdebug): Remove decl. This reverts a part of the
15870 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
15871 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
15873 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15875 * image.c: Various fixes to ImageMagick code comments.
15876 (Fimagemagick_types): Doc fix.
15878 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
15880 Minor fixes prompted by GCC 4.6.0 warnings.
15882 * xselect.c (converted_selections, conversion_fail_tag): Now static.
15884 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
15885 (x_clipboard_manager_save_all): Move extern decl to ...
15886 * xterm.h: ... here, so that it can be checked for consistency.
15888 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
15890 * xselect.c (x_clipboard_manager_save_frame)
15891 (x_clipboard_manager_save_all): New functions.
15892 (Fx_clipboard_manager_save): Lisp function deleted.
15894 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
15895 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
15897 * xterm.h: Update prototype.
15899 2011-05-28 William Xu <william.xwl@gmail.com>
15901 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
15902 exiting (Bug#8239).
15904 2011-05-28 Jim Meyering <meyering@redhat.com>
15906 Avoid a sign-extension bug in crypto_hash_function.
15907 * fns.c (to_uchar): Define.
15908 (crypto_hash_function): Use it to convert some newly-signed
15909 variables to unsigned, to avoid sign-extension bugs. For example,
15910 without this change, (md5 "truc") would evaluate to
15911 45723a2aff78ff4fff7fff1114760e62 rather than the expected
15912 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
15913 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
15915 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
15917 Integer overflow fixes.
15919 * dbusbind.c: Serial number integer overflow fixes.
15920 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
15921 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
15922 to hold a serial number that is too large for a fixnum.
15923 (Fdbus_method_return_internal, Fdbus_method_error_internal):
15924 Check for serial numbers out of range. Decode any serial number
15925 that was so large that it became a float. (Bug#8722)
15927 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
15928 (Fdbus_call_method, Fdbus_call_method_asynchronously):
15929 Use XFASTINT rather than XUINT when numbers are nonnegative.
15930 (xd_append_arg, Fdbus_method_return_internal):
15931 (Fdbus_method_error_internal): Likewise. Also, for unsigned
15932 arguments, check that Lisp number is nonnegative, rather than
15933 silently wrapping negative numbers around. (Bug#8722)
15934 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
15937 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
15939 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
15941 ccl: Add integer overflow checks.
15942 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
15943 (IN_INT_RANGE): New macros.
15944 (ccl_driver): Use them to check for integer overflow when
15945 decoding a CCL program. Many of the new checks are whether XINT (x)
15946 fits in int; it doesn't always, on 64-bit hosts. The new version
15947 doesn't catch all possible integer overflows, but it's an
15948 improvement. (Bug#8719)
15950 * alloc.c (make_event_array): Use XINT, not XUINT.
15951 There's no need for unsigned here.
15953 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
15954 This follows up to the 2011-05-06 change that substituted uintptr_t
15955 for EMACS_INT. This case wasn't caught back then.
15957 Rework Fformat to avoid integer overflow issues.
15958 * editfns.c: Include <float.h> unconditionally, as it's everywhere
15959 now (part of C89). Include <verify.h>.
15960 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
15961 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
15962 (Fformat): Avoid the prepass trying to compute sizes; it was only
15963 approximate and thus did not catch overflow reliably. Instead, walk
15964 through the format just once, formatting and computing sizes as we go,
15965 checking for integer overflow at every step, and allocating a larger
15966 buffer as needed. Keep track separately whether the format is
15967 multibyte. Keep only the most-recently calculated precision, rather
15968 than them all. Record whether each argument has been converted to
15969 string. Use EMACS_INT, not int, for byte and char and arg counts.
15970 Support field widths and precisions larger than INT_MAX. Avoid
15971 sprintf's undefined behavior with conversion specifications such as %#d
15972 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
15973 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
15974 formatting out-of-range floating point numbers with int
15975 formats. (Bug#8668)
15977 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
15979 * data.c: Avoid integer truncation in expressions involving floats.
15980 * data.c: Include <intprops.h>.
15981 (arith_driver): When there's an integer overflow in an expression
15982 involving floating point, convert the integers to floating point
15983 so that the resulting value does not suffer from catastrophic
15984 integer truncation. For example, on a 64-bit host (* 4
15985 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
15986 Do not rely on undefined behavior after integer overflow.
15988 merge count_size_as_multibyte, parse_str_to_multibyte
15989 * character.c, character.h (count_size_as_multibyte):
15990 Rename from parse_str_to_multibyte; all uses changed.
15991 Check for integer overflow.
15992 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
15993 since it's now a duplicate of the other. This is more of
15994 a character than a buffer op, so better that it's in character.c.
15995 * fns.c, print.c: Adjust to above changes.
15997 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
15999 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16001 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16003 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16004 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16005 (x_clipboard_manager_save): Now static.
16006 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16008 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16009 (crypto_hash_function): Now static.
16010 Fix pointer signedness problems. Avoid unnecessary initializations.
16012 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16014 * termhooks.h (Vselection_alist): Make it terminal-local.
16016 * terminal.c (create_terminal): Initialize it.
16018 * xselect.c: Support for clipboard managers.
16019 (Vselection_alist): Move to termhooks.h as terminal-local var.
16020 (LOCAL_SELECTION): New macro.
16021 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16022 (symbol_to_x_atom): Remove gratuitous arg.
16023 (x_handle_selection_request, lisp_data_to_selection_data)
16024 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16025 (x_own_selection, x_get_local_selection, x_convert_selection):
16026 New arg, specifying work frame. Use terminal-local Vselection_alist.
16027 (some_frame_on_display): Delete unused function.
16028 (Fx_own_selection_internal, Fx_get_selection_internal)
16029 (Fx_disown_selection_internal, Fx_selection_owner_p)
16030 (Fx_selection_exists_p): New optional frame arg.
16031 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16032 (x_handle_selection_clear): Don't treat other terminals with the
16033 same keyboard specially. Use the terminal-local Vselection_alist.
16034 (x_clear_frame_selections): Use Frun_hook_with_args.
16036 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16038 * xterm.h: Add support for those atoms.
16040 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16042 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16043 (converted_selections, conversion_fail_tag): New global variables.
16044 (x_selection_request_lisp_error): Free the above.
16045 (x_get_local_selection): Remove unnecessary code.
16046 (x_reply_selection_request): Args changed; handle arbitrary array
16047 of converted selections stored in converted_selections.
16048 Separate the XChangeProperty and SelectionNotify steps.
16049 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16050 (x_convert_selection): New function.
16051 (x_handle_selection_event): Simplify.
16052 (x_get_foreign_selection): Don't ignore incoming requests while
16053 waiting for an answer; this will fail when we implement
16054 SAVE_TARGETS, and seems unnecessary anyway.
16055 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16056 (Vx_sent_selection_functions): Doc fix.
16058 2011-05-26 Leo Liu <sdl.web@gmail.com>
16060 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16062 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16064 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16066 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16067 for fringe update if it has periodic bitmap.
16068 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16069 and fringe_bitmap_periodic_p.
16071 * fringe.c (get_fringe_bitmap_data): New function.
16072 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16073 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16074 row. Mark glyph row for fringe update if periodicity changed.
16076 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16077 for fringe update unless it has periodic bitmap.
16079 2011-05-25 Kenichi Handa <handa@m17n.org>
16081 * xdisp.c (get_next_display_element): Set correct it->face_id for
16082 a static composition.
16084 2011-05-24 Leo Liu <sdl.web@gmail.com>
16087 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16089 * fns.c (crypto_hash_function, Fsha1): New function.
16090 (Fmd5): Use crypto_hash_function.
16091 (syms_of_fns): Add Ssha1.
16093 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16095 * gnutls.c: Remove unused macros.
16096 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16097 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16098 Remove macros that are defined and never used.
16099 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16101 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16103 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16104 (Fx_get_selection_internal): Minor cleanup.
16105 (Fx_own_selection_internal): Rename arguments for consistency with
16108 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16110 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16112 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16114 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16116 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16118 * dispnew.c (scrolling_window): Don't exclude the case that the
16119 last enabled row in the desired matrix touches the bottom boundary.
16121 2011-05-21 Glenn Morris <rgm@gnu.org>
16123 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16124 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16125 and add some more files.
16127 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16129 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16130 report_file_error introduced by the change from 2011-05-07.
16132 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16134 * systime.h (Time): Define only if emacs is defined.
16135 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16136 where the include path doesn't have X11/X.h by default. See
16137 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16139 2011-05-20 Kenichi Handa <handa@m17n.org>
16141 * composite.c (find_automatic_composition): Fix previous change.
16143 2011-05-20 Glenn Morris <rgm@gnu.org>
16145 * lisp.mk: New file, split from Makefile.in.
16146 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16147 (shortlisp): Remove.
16148 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16150 2011-05-19 Glenn Morris <rgm@gnu.org>
16152 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16153 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16154 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16155 (lisp): Set the order to that of loadup.el.
16156 (shortlisp): Make it a copy of $lisp.
16157 (SOME_MACHINE_LISP): Remove.
16158 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16159 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16161 2011-05-18 Kenichi Handa <handa@m17n.org>
16163 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16164 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16165 (find_automatic_composition): Mostly rewrite for efficiency.
16167 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16169 * makefile.w32-in: Update dependencies.
16171 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16173 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16174 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16176 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16178 Fix some integer overflow issues, such as string length overflow.
16180 * insdel.c (count_size_as_multibyte): Check for string overflow.
16182 * character.c (lisp_string_width): Check for string overflow.
16183 Use EMACS_INT, not int, for string indexes and lengths; in
16184 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16185 the resulting string length overflows an EMACS_INT; instead,
16186 report a string overflow if no precision given. When checking for
16187 precision exhaustion, use a check that cannot possibly have
16188 integer overflow. (Bug#8675)
16189 * character.h (lisp_string_width): Adjust to new signature.
16191 * alloc.c (string_overflow): New function.
16192 (Fmake_string): Use it. This doesn't change behavior, but saves
16193 a few bytes and will simplify future changes.
16194 * character.c (string_escape_byte8): Likewise.
16195 * lisp.h (string_overflow): New decl.
16197 Fixups, following up to the user-interface timestamp change.
16198 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16199 for UI timestamps, instead of unsigned long.
16200 * msdos.c (mouse_get_pos): Likewise.
16201 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16202 * w32gui.h (Time): Define by including "systime.h" rather than by
16203 declaring it ourselves. (Bug#8664)
16205 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16206 * image.c (clear_image_cache): Likewise.
16208 * term.c (term_mouse_position): Don't assume time_t wraparound.
16210 Be more systematic about user-interface timestamps.
16211 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16212 and sometimes 'EMACS_UINT', to represent these timestamps.
16213 This change causes it to use 'Time' uniformly, as that's what X uses.
16214 This makes the code easier to follow, and makes it easier to catch
16215 integer overflow bugs such as Bug#8664.
16216 * frame.c (Fmouse_position, Fmouse_pixel_position):
16217 Use Time, not unsigned long, for user-interface timestamps.
16218 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16219 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16220 * keyboard.h (last_event_timestamp): Likewise.
16221 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16222 * menu.h (xmenu_show): Likewise.
16223 * term.c (term_mouse_position): Likewise.
16224 * termhooks.h (struct input_event.timestamp): Likewise.
16225 (struct terminal.mouse_position_hook): Likewise.
16226 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16227 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16228 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16229 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16230 what it was before.
16231 * menu.h, termhooks.h: Include "systime.h", for Time.
16233 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16234 Don't assume that the difference between two unsigned long values
16235 can fit into an integer. At this point, we know button_down_time
16236 <= event->timestamp, so the difference must be nonnegative, so
16237 there's no need to cast the result if double-click-time is
16238 nonnegative, as it should be; check that it's nonnegative, just in
16239 case. This bug is triggered when events are more than 2**31 ms
16240 apart (about 25 days). (Bug#8664)
16242 * xselect.c (last_event_timestamp): Remove duplicate decl.
16243 (x_own_selection): Remove needless cast to unsigned long.
16245 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16246 that always fit in int. Use a sentinel instead of a counter, to
16247 avoid a temp and to allay GCC's concerns about possible int overflow.
16248 * frame.h (struct frame): Use int for menu_bar_items_used
16249 instead of EMACS_INT, since it always fits in int.
16251 * menu.c (grow_menu_items): Check for int overflow.
16253 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16255 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16256 Before, the code was not consistent. These values cannot exceed
16257 2**31 - 1 so there's no need to make them unsigned.
16258 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16259 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16260 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16262 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16264 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16265 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16266 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16267 presumably because the widths might not match.
16269 * window.c (size_window): Avoid needless test at loop start.
16271 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16273 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16275 2011-05-12 Drew Adams <drew.adams@oracle.com>
16277 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16279 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16281 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16282 `width' to `bar_area_x' and `bar_area_width', respectively.
16283 (x_scroll_run): Take account of fringe background extension.
16285 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16286 Rename local vars `left' and `width' to `bar_area_x' and
16287 `bar_area_width', respectively.
16288 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16289 background extension.
16291 2011-05-10 Jim Meyering <meyering@redhat.com>
16293 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16295 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16297 * image.c (Finit_image_library): Return t for built-in image types,
16298 like pbm and xbm. (Bug#8640)
16300 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16302 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16304 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16306 * w32console.c (Fset_screen_color): Doc fix.
16307 (Fget_screen_color): New function.
16308 (syms_of_ntterm): Defsubr it.
16310 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16311 unlink the temporary file if Fcall_process didn't create it in the
16313 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16314 child process will be redirected to a file specified with `:file'.
16315 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16316 cue to call_process_cleanup not to close that handle.
16318 2011-05-07 Ben Key <bkey76@gmail.com>
16320 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16321 one of two shell specific rules, either bootstrap-temacs-CMD or
16322 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16323 to the previous implementation of the bootstrap-temacs rule.
16324 The bootstrap-temacs-CMD rule is similar to the previous
16325 implementation of the bootstrap-temacs rule except that it
16326 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16329 These changes, along with some changes to nt/configure.bat,
16330 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16331 earlier fix to add support for --cflags and --ldflags options
16332 that include quotes so that it works whether make uses cmd or
16335 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16337 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16338 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16340 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16341 a string. Handle both cases.
16342 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16343 (Fdbus_register_method): Use Qinvalid_function.
16345 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16347 * makefile.w32-in: Update dependencies.
16348 (LISP_H): Add inttypes.h and stdin.h.
16349 (PROCESS_H): Add unistd.h.
16351 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16353 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16354 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16356 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16358 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16360 * term.c (vfatal): Remove stray call to va_end.
16361 It's not needed and the C Standard doesn't allow it here anyway.
16363 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16364 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16366 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16369 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16371 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16373 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16375 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16377 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16379 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16380 * charset.c (Fdefine_charset_internal): Don't initialize
16381 charset.code_space[15]. The value was garbage, on hosts with
16382 32-bit int (Bug#8600).
16384 * lread.c (read_integer): Be more consistent with string-to-number.
16385 Use string_to_number to do the actual conversion; this avoids
16386 rounding errors and fixes some other screwups. Without this fix,
16387 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16388 (digit_to_number): Move earlier, for benefit of read_integer.
16389 Return -1 if the digit is out of range for the base, -2 if it is
16390 not a digit in any supported base. (Bug#8602)
16392 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16394 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16395 to match comment at start of function. This also removes a
16396 GCC warning about overflow in a 32+64-bit port.
16398 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16400 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16401 Reported by Stefan Monnier in
16402 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16403 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16404 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16406 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16407 (EMACS_UINTPTR): Likewise, with uintptr_t.
16409 * lisp.h: Prefer 64-bit EMACS_INT if available.
16410 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16411 on 32-bit hosts that have 64-bit int, so that they can access
16413 However, temporarily disable this change unless the temporary
16414 symbol WIDE_EMACS_INT is defined.
16416 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16418 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16419 This removes an assumption that EMACS_INT and long are the same
16420 width as pointers. The assumption is true for Emacs porting targets
16421 now, but we want to make other targets possible.
16422 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16423 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16424 In the rest of the code, change types of integers that hold casted
16425 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16426 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16427 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16428 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16429 No need to cast type when ORing.
16430 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16431 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16432 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16433 assume EMACS_INT is the same width as char *.
16434 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16435 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16436 Remove no-longer-needed casts.
16437 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16438 (xg_tool_bar_help_callback, xg_make_tool_item):
16439 Use EMACS_INTPTR to hold an integer
16440 that will be cast to void *; this can avoid a GCC warning
16441 if EMACS_INT is not the same width as void *.
16442 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16443 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16444 (current_message_1, set_message_1):
16445 Use a local to convert to proper width without a cast.
16446 * xmenu.c (dialog_selection_callback): Likewise.
16448 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16449 Also, don't assume VALBITS / RAND_BITS is less than 5,
16450 and don't rely on undefined behavior when shifting a 1 left into
16452 * lisp.h (get_random): Change signature to match.
16454 * lread.c (hash_string): Use size_t, not int, for hash computation.
16455 Normally we prefer signed values; but hashing is special, because
16456 it's better to use unsigned division on hash table sizes so that
16457 the remainder is nonnegative. Also, size_t is the natural width
16458 for hashing into memory. The previous code used 'int', which doesn't
16459 retain enough info to hash well into very large tables.
16460 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16462 * dbusbind.c: Don't possibly lose pointer info when converting.
16463 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16464 Use XPNTR rather than XHASH, so that the high-order bits of
16465 the pointer aren't lost when converting through void *.
16467 * eval.c (Fautoload): Don't double-shift a pointer.
16469 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16471 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16473 * gnutls.c (DEF_GNUTLS_FN):
16474 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16476 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16478 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16481 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16483 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16484 New version that can reserve upto 2GB of heap space.
16486 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16488 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16490 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16492 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16493 `gnutls_certificate_set_x509_key_file'.
16495 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16497 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16498 Update dependencies.

16552 * process.c: Include lisp.h before w32.h, not after.
16553 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16554 instead of gnutls_record_check_pending.

16631 %llo or %llx format is passed. (Bug#8545)
16633 * window.c (window_scroll_line_based): Use a marker instead of
16634 simple variables to record original value of point. (Bug#7952)

16637 produced by %s or %c overflows available buffer space. (Bug#8545)
16639 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16641 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

16644 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16646 * w32.c (init_environment): Warn about defaulting HOME to C:\.
16648 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16650 * keyboard.c (Qdelayed_warnings_hook): Define.
16651 (command_loop_1): Run `delayed-warnings-hook'
16652 if Vdelayed_warnings_list is non-nil.
16653 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16654 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16656 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16658 * doprnt.c (doprnt): Don't return value smaller than the buffer
16659 size if the message was truncated. (Bug#8545).
16661 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16663 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16664 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16666 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16668 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16670 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16672 * makefile.w32-in: Update dependencies.
16674 2011-04-27 Eli Zaretskii <eliz@gnu.org>
16676 Improve `doprnt' and its usage. (Bug#8545)
16677 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16678 `format_end'. Remove support for %l as a conversion specifier.
16679 Don't use xrealloc. Improve diagnostics when the %l size modifier
16680 is used. Update the commentary.
16682 * eval.c (verror): Simplify calculation of size_t.
16684 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16687 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16689 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16692 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16694 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16695 This makes this file independent of the recent pseudovector change.
16697 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16699 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16701 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16702 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16703 Remove unused local.
16704 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16706 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16707 GCC 4.6.0 optimizes based on type-based alias analysis.
16708 For example, if b is of type struct buffer * and v of type struct
16709 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16710 != &v->size, and therefore "v->size = 1; b->size = 2; return
16711 v->size;" must therefore return 1. This assumption is incorrect
16712 for Emacs, since it type-puns struct Lisp_Vector * with many other
16713 types. To fix this problem, this patch adds a new type struct
16714 vectorlike_header that documents the constraints on layout of vectors
16715 and pseudovectors, and helps optimizing compilers not get fooled
16716 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16717 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16718 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16720 (XSETPVECTYPE): Rewrite in terms of new macro.
16721 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16722 This is a bit clearer, and further avoids the possibility of
16723 undesirable aliasing.
16724 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16725 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16726 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16727 since Lisp_Subr is a special case (no "next" field).
16728 (ASIZE): Now uses header.size rather than size.
16729 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16730 to avoid the hassle of writing XVECTOR (foo)->header.size.
16731 (struct vectorlike_header): New type.
16732 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16733 object, to help avoid aliasing.
16734 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
16735 (SUBRP): Likewise, since Lisp_Subr is a special case.
16736 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
16737 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
16738 (struct Lisp_Hash_Table): Combine first two members into a single
16739 struct vectorlike_header member. All uses of "size" and "next" members
16740 changed to be "header.size" and "header.next".
16741 * buffer.h (struct buffer): Likewise.
16742 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
16743 * frame.h (struct frame): Likewise.
16744 * process.h (struct Lisp_Process): Likewise.
16745 * termhooks.h (struct terminal): Likewise.
16746 * window.c (struct save_window_data, struct saved_window): Likewise.
16747 * window.h (struct window): Likewise.
16748 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
16749 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
16750 * buffer.c (init_buffer_once): Likewise.
16751 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
16753 * process.c (Fformat_network_address): Use local var for size,
16756 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
16758 Make the Lisp reader and string-to-float more consistent (Bug#8525)
16759 * data.c (atof): Remove decl; no longer used or needed.
16760 (digit_to_number): Move to lread.c.
16761 (Fstring_to_number): Use new string_to_number function, to be
16762 consistent with how the Lisp reader treats infinities and NaNs.
16763 Do not assume that floating-point numbers represent EMACS_INT
16764 without losing information; this is not true on most 64-bit hosts.
16765 Avoid double-rounding errors, by insisting on integers when
16766 parsing non-base-10 numbers, as the documentation specifies.
16767 * lisp.h (string_to_number): New decl, replacing ...
16768 (isfloat_string): Remove.
16769 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
16770 (read1): Do not accept +. and -. as integers; this
16771 appears to have been a coding error. Similarly, do not accept
16772 strings like +-1e0 as floating point numbers. Do not report
16773 overflow for integer overflows unless the base is not 10 which
16774 means we have no simple and reliable way to continue.
16775 Break out the floating-point parsing into a new
16776 function string_to_number, so that Fstring_to_number parses
16777 floating point numbers consistently with the Lisp reader.
16778 (digit_to_number): Move here from data.c. Make it static inline.
16779 (E_CHAR, EXP_INT): Remove, replacing with ...
16780 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
16781 (string_to_number): New function, replacing isfloat_string.
16782 This function checks for valid syntax and produces the resulting
16783 Lisp float number too. Rework it so that string-to-number
16784 no longer mishandles examples like "1.0e+". Use strtoumax,
16785 so that overflow for non-base-10 numbers is reported only when
16786 there's no portable and simple way to convert to floating point.
16788 * textprop.c (set_text_properties_1): Rewrite for clarity,
16789 and to avoid GCC warning about integer overflow.
16791 * intervals.h (struct interval): Use EMACS_INT for members
16792 where EMACS_UINT might cause problems. See
16793 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
16794 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
16795 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
16797 (offset_intervals): Tell GCC not to worry about length overflow
16798 when negating a negative length.
16800 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
16801 (overrun_check_free): Likewise.
16803 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
16804 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
16807 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16808 (gnutls_make_error): Rename local to avoid shadowing.
16809 (gnutls_emacs_global_deinit): ifdef out; not used.
16810 (Fgnutls_boot): Use const for pointer to readonly storage.
16811 Comment out unused local. Fix pointer signedness problems.
16813 * lread.c (openp): Don't stuff size_t into an 'int'.
16814 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
16815 about possible signed overflow.
16817 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
16818 (GDK_KEY_g): Don't define if already defined.
16819 (xg_prepare_tooltip): Avoid pointer signedness problem.
16820 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
16822 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
16823 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
16825 * xfns.c (Fx_window_property): Simplify a bit,
16826 to make a bit faster and to avoid GCC 4.6.0 warning.
16827 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
16829 * fns.c (internal_equal): Don't assume size_t fits in int.
16831 * alloc.c (compact_small_strings): Tighten assertion a little.
16833 Replace pEd with more-general pI, and fix some printf arg casts.
16834 * lisp.h (pI): New macro, generalizing old pEd macro to other
16835 conversion specifiers. For example, use "...%"pI"d..." rather
16836 than "...%"pEd"...".
16837 (pEd): Remove. All uses replaced with similar uses of pI.
16838 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
16839 * alloc.c (check_pure_size): Don't overflow by converting size to int.
16840 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
16841 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
16842 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
16843 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
16844 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
16846 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
16847 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
16848 * print.c (safe_debug_print, print_object): Likewise.
16849 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
16851 Use pI instead of if-then-else-abort. Use %p to avoid casts,
16852 avoiding the 0 flag, which is not portable.
16853 * process.c (Fmake_network_process): Use pI to avoid cast.
16854 * region-cache.c (pp_cache): Likewise.
16855 * xdisp.c (decode_mode_spec): Likewise.
16856 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
16857 behavior on 64-bit hosts with printf arg.
16858 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
16859 (x_stop_queuing_selection_requests): Likewise.
16860 (x_get_window_property): Don't truncate byte count to an 'int'
16863 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
16864 here, since it parses constructs like leading '-' and spaces,
16865 which are not wanted; and it overflows with large numbers.
16866 Instead, simply match F[0-9]+, which is what is wanted anyway.
16868 * alloc.c: Remove unportable assumptions about struct layout.
16869 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
16870 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
16871 (allocate_vectorlike, make_pure_vector): Use the new macros,
16872 plus offsetof, to remove unportable assumptions about struct layout.
16873 These assumptions hold on all porting targets that I know of, but
16874 they are not guaranteed, they're easy to remove, and removing them
16875 makes further changes easier.
16877 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
16878 This doesn't fix a bug but makes the code clearer.
16879 (string_overrun_cookie): Now const. Use initializers that
16880 don't formally overflow signed char, to avoid warnings.
16881 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
16882 can cause Emacs to crash when string overrun checking is enabled.
16883 (allocate_buffer): Don't assume sizeof (struct buffer) is a
16884 multiple of sizeof (EMACS_INT); it need not be, if
16885 alignof(EMACS_INT) < sizeof (EMACS_INT).
16886 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
16888 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
16890 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
16892 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
16894 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
16895 supposed to be handshaking. (Bug#8556)
16896 Reported by Paul Eggert <eggert@cs.ucla.edu>.
16898 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
16900 * lisp.h (Qdebug): List symbol.
16901 * eval.c (Qdebug): Restore global linkage.
16902 * keyboard.c (debug-on-event): New variable.
16903 (handle_user_signal): Break into debugger when debug-on-event
16904 matches the current signal symbol.
16906 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
16908 * alloc.c (check_sblock, check_string_bytes)
16909 (check_string_free_list): Convert to standard C.
16911 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
16913 * w32.c (emacs_gnutls_push): Fix typo.
16915 2011-04-25 Eli Zaretskii <eliz@gnu.org>

17431 However, leave prepare_to_modify_buffer alone. It's never

17469 * xfaces.c (face_at_string_position):
17470 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,

17639 Declare Lisp_Object Q* variables to be 'static' if not exported.
17640 This makes it easier for human readers (and static analyzers)
17641 to see whether these variables are used from other modules.

17655 * lisp.h (DEFINE_FUNC): Make sname 'static'.
17657 Make Emacs functions such as Fatom 'static' by default.
17658 This makes it easier for human readers (and static analyzers)
17659 to see whether these functions can be called from other modules.
17660 DEFUN now defines a static function. To make the function external
17661 so that it can be used in other C modules, use the new macro DEFUE.

17667 Remove decls, since these functions are now static.
17668 (Funintern, Fget_internal_run_time): New decls, since these functions
17669 were already external.
17671 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

17679 Mark functions with DEFUE instead of DEFUN,
17680 if they are used in other modules.
17681 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
17682 decls for now-static functions.
17683 * buffer.h (Fdelete_overlay): Remove decl.

17719 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17721 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17722 when at ZV. (Bug#8487)
17724 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17726 * charset.c (Fclear_charset_maps): Use xfree instead of free.

17735 (overrun_check_free): Protoize.
17737 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
17739 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
17740 since callers should never pass a negative size.
17741 Change the signature to match that of plain 'read' and 'write'; see
17742 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
17743 * lisp.h: Update prototypes of emacs_write and emacs_read.
17745 2011-04-11 Eli Zaretskii <eliz@gnu.org>
17747 * xdisp.c (redisplay_window): Don't try to determine the character
17748 position of the scroll margin if the window start point w->startp
17749 is outside the buffer's accessible region. (Bug#8468)
17751 2011-04-10 Eli Zaretskii <eliz@gnu.org>
17753 Fix write-region and its subroutines for buffers > 2GB.
17754 * fileio.c (a_write, e_write): Modify declaration of arguments and
17755 local variables to support buffers larger than 2GB.
17756 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
17758 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
17759 argument, local variables, and return value.
17761 * lisp.h: Update prototypes of emacs_write and emacs_read.
17763 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
17765 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
17767 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
17769 Fix more problems found by GCC 4.6.0's static checks.
17771 * xdisp.c (vmessage): Use a better test for character truncation.
17773 * charset.c (load_charset_map): <, not <=, for optimization,
17774 and to avoid potential problems with integer overflow.
17775 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
17776 * casetab.c (set_identity, shuffle): Likewise.
17777 * editfns.c (Fformat): Likewise.
17778 * syntax.c (skip_chars): Likewise.
17780 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
17781 This also lets GCC 4.6.0 generate slightly better loop code.
17783 * callint.c (Fcall_interactively): <, not <=, for optimization.
17784 (Fcall_interactively): Count the number of arguments produced,
17785 not the number of arguments given. This is simpler and lets GCC
17786 4.6.0 generate slightly better code.
17788 * ftfont.c: Distingish more carefully between FcChar8 and char.
17789 The previous code passed unsigned char * to a functions like
17790 strlen and xstrcasecmp that expect char *, which does not
17791 conform to the C standard.
17792 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
17793 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
17794 char * when the C standard requires it.
17796 * keyboard.c (read_char): Remove unused var.
17798 * eval.c: Port to Windows vsnprintf (Bug#8435).
17799 Include <limits.h>.
17800 (SIZE_MAX): Define if the headers do not.
17801 (verror): Do not give up if vsnprintf returns a negative count.
17802 Instead, grow the buffer. This ports to Windows vsnprintf, which
17803 does not conform to C99. Problem reported by Eli Zaretskii.
17804 Also, simplify the allocation scheme, by avoiding the need for
17805 calling realloc, and removing the ALLOCATED variable.
17807 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
17809 Remove invocations of doprnt, as Emacs now uses vsnprintf.
17810 But keep the doprint source code for now, as we might revamp it
17811 and use it again (Bug#8435).
17812 * lisp.h (doprnt): Remove.
17813 * Makefile.in (base_obj): Remove doprnt.o.
17814 * deps.mk (doprnt.o): Remove.
17816 error: Print 32- and 64-bit integers portably (Bug#8435).
17817 Without this change, on typical 64-bit hosts error ("...%d...", N)
17818 was used to print both 32- and 64-bit integers N, which relied on
17819 undefined behavior.
17820 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.

17825 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
17826 Truncate the output at a character boundary, since vsnprintf does not
17828 * charset.c (check_iso_charset_parameter): Convert internal
17829 character to string before calling 'error', since %c now has the
17831 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
17832 overflow when computing char to be passed to 'error'. Do not
17833 pass Lisp_Object to 'error'; pass the integer instead.
17834 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
17835 formatted with plain %d.
17837 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
17839 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.

17851 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
17852 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
17853 return ssize_t not "int", and use size_t as the buffer length.
17854 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
17855 * gnutls.h: Update declarations.
17856 * process.c (read_process_output): Use ssize_t, to match.

17861 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
17863 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
17865 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
17866 Use unsigned char, to match FcChar8 type definition.
17868 * xterm.c (handle_one_xevent):
17869 * xmenu.c (create_and_show_popup_menu):
17870 * xselect.c (x_decline_selection_request)
17871 (x_reply_selection_request): Avoid type-punned deref of X events.
17873 2011-04-09 Eli Zaretskii <eliz@gnu.org>

17902 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
17903 (encode_invocation_designation): Last argument P_NCHARS is now
17905 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.

17972 This avoids several warnings with gcc -Wstrict-overflow.
17973 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
17974 directly, rather than having caller test rule sign. This avoids
17975 some unnecessary tests.
17976 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
17977 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
17978 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
17980 * xfont.c (xfont_text_extents): Remove var that was set but not used.
17981 (xfont_open): Avoid unnecessary tests.
17983 * composite.c (composition_gstring_put_cache): Use unsigned integer.

17989 breaking out part of COMPOSITION_DECODE_RULE.
17990 (COMPOSITION_DECODE_RULE): Use it.

17992 by using the new macro.
17994 * textprop.c (set_text_properties_1): Change while to do-while,
17995 since the condition is always true at first.
17997 * intervals.c (graft_intervals_into_buffer): Mark var as used.
17998 (interval_deletion_adjustment): Return unsigned value.
18001 * process.c (list_processes_1, create_pty, read_process_output):

18017 * print.c (print_error_message): Avoid int overflow.
18019 * font.c (font_list_entities): Redo for clarity,
18020 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18022 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18023 (font_score): Avoid potential overflow in diff calculation.
18025 * fns.c (substring_both): Remove var that is set but not used.
18026 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18028 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18030 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18031 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18032 can always succeed if overflow has undefined behavior.
18034 * search.c (boyer_moore, wordify): Remove vars set but not used.
18035 (wordify): Omit three unnecessary tests.
18037 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18038 All callers changed. This avoids the need for an unused var.
18040 * casefiddle.c (casify_region): Remove var that is set but not used.
18042 * dired.c (file_name_completion): Remove var that is set but not used.
18044 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18046 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18047 (Finsert_file_contents): Remove unnecessary code checking fd.
18049 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18050 Check for integer overflow on size calculations.
18052 * buffer.c (Fprevious_overlay_change): Remove var that is set
18055 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18056 Remove vars that are set but not used.
18057 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.

18060 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18062 * image.c (lookup_image): Remove var that is set but not used.
18063 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18065 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18066 that are set but not used.
18068 * xfns.c (make_invisible_cursor): Don't return garbage
18069 if XCreateBitmapFromData fails (Bug#8410).
18071 * xselect.c (x_get_local_selection, x_handle_property_notify):
18072 Remove vars that are set but not used.
18074 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18075 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
18077 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
18078 Remove var that is set but not used.
18079 (scroll_bar_windows_size): Now size_t, not int.
18080 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
18081 Check for overflow.
18083 * xfaces.c (realize_named_face): Remove vars that are set but not used.
18084 (map_tty_color) [!defined MSDOS]: Likewise.

18092 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18093 (decode_coding_charset): Remove vars that are set but not used.
18095 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18096 that is set but not used.
18098 * print.c (print_object): Remove var that is set but not used.
18100 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18101 The gnulib version avoids calling malloc in the usual case,
18102 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18103 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18104 * filelock.c (current_lock_owner): Likewise.
18105 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18106 * sysdep.c: Include allocator.h, careadlinkat.h.
18107 (emacs_no_realloc_allocator): New static constant.
18108 (emacs_readlink): New function.
18109 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18110 ../lib/careadlinkat.h.
18112 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18114 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18115 first non-nil return value).

18129 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18130 and thereabouts. All callers changed.
18131 (get_per_char_metric): Remove parameter `f', unused since
18132 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

18136 do not dereference NULL upon failed strdup
18137 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.

18166 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
18168 * keyboard.c (eval_dyn): New fun.
18169 (menu_item_eval_property): Use it.
18171 * image.c (parse_image_spec): Use Ffunctionp.
18173 * fns.c (concat, mapcar1): Accept byte-code-functions.
18175 * eval.c (Fsetq): Handle lexical vars.
18176 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18177 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18178 (FletX, Flet): Obey lexical binding.
18179 (Fcommandp): Handle closures.
18180 (Feval): New `lexical' arg.
18181 (eval_sub): New function extracted from Feval. Use it almost
18182 everywhere where Feval was used. Look up vars in lexical env.
18184 (Ffunctionp): Move from subr.el.
18185 (Ffuncall): Handle closures.
18186 (apply_lambda): Remove `eval_flags'.
18187 (funcall_lambda): Handle closures and new byte-code-functions.
18188 (Fspecial_variable_p): New function.
18189 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18190 but without exporting it to Lisp.
18192 * doc.c (Fdocumentation, store_function_docstring):
18193 * data.c (Finteractive_form): Handle closures.
18195 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18198 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18200 (exec_byte_code): New function extracted from Fbyte_code to handle new
18201 calling convention for byte-code-functions. Add new byte-codes.
18203 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
18205 * alloc.c (Fmake_symbol): Init new `declared_special' field.

18215 Limit scrolling to 100 screen lines.
18216 (redisplay_window): Even when falling back on "recentering",
18217 position point in the window according to scroll-conservatively,
18218 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18220 (try_scrolling): When point is above the window, allow searching
18221 as far as scroll_max, or one screenful, to compute vertical
18222 distance from PT to the scroll margin position. This prevents
18223 try_scrolling from unnecessarily failing when
18224 scroll-conservatively is set to a value slightly larger than the
18225 window height. Clean up the case of PT below the margin at bottom
18226 of window: scroll_max can no longer be INT_MAX. When aggressive
18227 scrolling is in use, don't let point enter the opposite scroll
18228 margin as result of the scroll.
18229 (syms_of_xdisp) <scroll-conservatively>: Document the
18230 threshold of 100 lines for never-recentering scrolling.

18238 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18239 (redisplay_internal): Remove parameter `preserve_echo_area',
18240 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18242 * indent.c (Fvertical_motion):
18243 * window.c (window_scroll_pixel_based, Frecenter):
18244 Don't pass `need_y_p' to `move_it_by_lines'.
18246 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18248 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18249 steal a few bits to be more compact.

18251 Remove unneeded casts.
18253 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18255 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18257 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18258 binding" message (bug#7967).

18264 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18265 Remove unused local var.
18267 * editfns.c (Fmessage_box): Remove unused local var.
18269 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18270 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18271 Omit unused local vars.
18272 * window.c (shrink_windows): Omit unused local var.
18273 * menu.c (digest_single_submenu): Omit unused local var.
18274 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18275 Omit unused local var.
18277 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18278 Don't assume string length fits in int.
18279 (keyremap_step, read_key_sequence): Use size_t for sizes.
18280 (read_key_sequence): Don't check last_real_key_start redundantly.
18282 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18283 instead of alloca (Bug#8344).
18285 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18286 (Fbacktrace_frame): Don't assume nframes fits in int.
18288 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18290 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18293 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18295 * cm.c (calccost): Turn while-do into do-while, for clarity.
18297 * keyboard.c (syms_of_keyboard): Use the same style as later
18298 in this function when indexing through an array. This also
18299 works around GCC bug 48267.
18301 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18303 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

18306 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18308 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18309 This avoids undefined behavior on integer overflow, and is a bit
18310 more convenient anyway since it is compared to a size_t variable.
18312 Variadic C functions now count arguments with size_t, not int.
18313 This avoids an unnecessary limitation on 64-bit machines, which
18314 caused (substring ...) to crash on large vectors (Bug#8344).
18315 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18316 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

18322 (internal_condition_case_n, run_hook_with_args, apply_lambda)
18323 (funcall_lambda, mark_backtrace): Likewise.
18324 * fns.c (concat): Likewise.
18325 * frame.c (x_set_frame_parameters): Likewise.
18326 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18327 0 if not found, not -1. All callers changed.
18329 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18330 (stack_copy_size): Now size_t, not int.
18331 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

18337 All callers changed.
18339 * lisp.h (multibyte_char_to_unibyte):
18340 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18341 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

18351 * keyboard.c (safe_run_hook_funcall): New function.
18352 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18353 don't set the hook to nil, but remove the offending function instead.
18354 (Qcommand_hook_internal): Remove, unused.
18355 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18356 Vcommand_hook_internal.
18358 * eval.c (enum run_hooks_condition): Remove.
18359 (funcall_nil, funcall_not): New functions.
18360 (run_hook_with_args): Call each function through a `funcall' argument.

18370 * print.c (strout): Remove parameter `multibyte', unused since
18371 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18373 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18374 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

18387 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
18388 All callers changed.
18390 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
18392 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

18421 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
18423 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
18425 * w32.c (read_unc_volume): Use parameter `henum', instead of
18426 global variable `wget_enum_handle'.
18428 * keymap.c (describe_vector): Remove parameters `indices' and

18524 2011-03-23 Julien Danjou <julien@danjou.info>
18526 * term.c (Fsuspend_tty, Fresume_tty):
18527 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18528 * window.c (temp_output_buffer_show):

18535 * callint.c (Fcall_interactively):
18536 * buffer.c (Fkill_all_local_variables):
18537 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18539 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18540 unconditionally since it does the check itself.
18542 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18544 Fix more problems found by GCC 4.5.2's static checks.
18546 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18547 the first time through the loop, since we know p0 < p1 then.
18548 This also avoids a gcc -Wstrict-overflow warning.
18550 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18551 leading to a memory leak, possible in functions like
18552 load_charset_map_from_file that can allocate an unbounded number
18553 of objects (Bug#8318).
18555 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18556 that could (at least in theory) be that large.
18558 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18559 This is less likely to overflow, and avoids undefined behavior if
18560 overflow does occur. All callers changed. Use strtoul to scan
18561 for the unsigned long integer.
18562 (pint2hrstr): Simplify and tune code slightly.
18563 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

18578 * process.c (Fmake_network_process): Use socklen_t, not int,
18579 where POSIX says socklen_t is required in portable programs.
18580 This fixes a porting bug on hosts like 64-bit HP-UX, where
18581 socklen_t is wider than int (Bug#8277).
18582 (Fmake_network_process, server_accept_connection):
18583 (wait_reading_process_output, read_process_output):
18586 * process.c: Rename or move locals to avoid shadowing.

18593 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
18594 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
18596 Make tparam.h and terminfo.c consistent.
18597 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18598 Include tparam.h instead, since it declares them.
18599 * cm.h (PC): Remove extern decl; tparam.h now does this.
18600 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18601 * terminfo.c: Include tparam.h, to check interfaces.
18602 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18603 (tparam): Adjust signature to match interface in tparam.h;
18604 this removes some undefined behavior. Check that outstring and len
18605 are zero, which they always are with Emacs.
18606 * tparam.h (PC, BC, UP): New extern decls.
18608 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18609 (xftfont_open): Rename locals to avoid shadowing.
18611 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
18612 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

18614 (ftfont_list): Remove unused local.
18615 (get_adstyle_property, ftfont_pattern_entity):
18616 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
18617 Rename locals to avoid shadowing.
18619 * xfont.c (xfont_list_family): Mark var as initialized.
18621 * xml.c (make_dom): Now static.
18623 * composite.c (composition_compute_stop_pos): Rename local to
18625 (composition_reseat_it): Remove unused locals.
18626 (find_automatic_composition, composition_adjust_point): Likewise.
18627 (composition_update_it): Mark var as initialized.
18628 (find_automatic_composition): Mark vars as initialized,
18629 with a FIXME (Bug#8290).
18631 character.h: Rename locals to avoid shadowing.
18632 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
18633 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18634 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18635 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18636 to avoid shadowing.
18638 * textprop.c (property_change_between_p): Remove; unused.
18640 * intervals.c (interval_start_pos): Now static.
18642 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
18644 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
18645 Rename locals to avoid shadowing.
18647 * sound.c (wav_play, au_play, Fplay_sound_internal):
18648 Fix pointer signedness.
18649 (alsa_choose_format): Remove unused local var.
18650 (wav_play): Initialize a variable to 0, to prevent undefined
18651 behavior (Bug#8278).
18653 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18655 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18657 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18658 clobbering (Bug#8298).
18659 * sysdep.c (sys_subshell): Likewise.
18660 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18662 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18663 This should get cleaned up, so that child_setup has the
18664 same signature on all platforms.
18666 * callproc.c (call_process_cleanup): Now static.
18667 (relocate_fd): Rename locals to avoid shadowing.
18669 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18671 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18672 not to be necessary, and produces flickering.
18674 2011-03-20 Glenn Morris <rgm@gnu.org>
18676 * config.in: Remove file.
18678 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
18680 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
18681 are now in src/globals.h.
18682 (syms_of_minibuf): Remove spurious & from previous change.

18699 2011-03-17 Eli Zaretskii <eliz@gnu.org>
18701 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

18797 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
18798 some of which prompt warnings from gcc -Wbad-function-cast.
18799 (Fformat_time_string, Fencode_time, Finsert_char):

18828 (Fmemory_limit): Cast sbrk's returned value to char *.
18830 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

18836 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18837 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
18838 to use the following functions instead of these macros.
18839 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
18840 EMACS_INT, since callers assume the returned value fits in int.
18841 (upcase1): Likewise, for UPCASE_TABLE.
18842 (uppercasep, lowercasep, upcase): New static inline functions.
18843 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

18853 (regex_compile, re_match_2_internal): Mark locals as initialized.
18854 (RETALLOC_IF): Define only if needed.
18855 (WORDCHAR_P): Likewise. This one is never needed, but is used
18856 only in a comment talking about a compiler bug, so put inside
18857 the #if 0 of that comment.
18858 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
18859 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

18885 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
18886 New macros, so that the caller can use some names other than
18887 gcpro1, gcpro2, etc.
18888 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
18890 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
18891 argument, for consistency with GCPRO2_VAR, etc: it is now the
18892 prefix of the variable, not the variable itself. All uses
18894 * dired.c (directory_files_internal, file_name_completion):
18895 Rename locals to avoid shadowing.
18897 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
18898 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
18899 dired.c's scmp function, had undefined behavior.
18900 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
18901 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
18902 * buffer.h: ... to here, because these macros use current_buffer,
18903 and the new implementation with inline functions needs to have
18904 current_buffer in scope now, rather than later when the macros
18906 (downcase, upcase1): New static inline functions.
18907 (DOWNCASE, UPCASE1): Reimplement using these functions.
18908 This avoids undefined behavior in expressions like
18909 DOWNCASE (x) == DOWNCASE (y), which previously suffered
18910 from race conditions in accessing the global variables
18911 case_temp1 and case_temp2.
18912 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
18913 * lisp.h (case_temp1, case_temp2): Remove their decls.
18914 * character.h (ASCII_CHAR_P): Move from here ...
18915 * lisp.h: ... to here, so that the inline functions mentioned
18916 above can use them.
18918 * dired.c (directory_files_internal_unwind): Now static.
18920 * fileio.c (file_name_as_directory, directory_file_name):

18923 (file_name_as_directory): Use const pointers when appropriate.
18924 (Fexpand_file_name): Likewise. In particular, newdir might
18925 point at constant storage, so make it a const pointer.
18926 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
18927 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
18929 (Fset_file_times, Finsert_file_contents, auto_save_error):

18934 to avoid shadowing.
18936 * marker.c (bytepos_to_charpos): Remove; unused.
18938 * lisp.h (verify_bytepos, count_markers): New decls,
18939 so that gcc does not warn that these functions aren't declared.
18941 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
18942 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
18943 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
18944 (copy_text): Remove unused local var.
18946 * filelock.c (within_one_second): Now static.
18947 (lock_file_1): Rename local to avoid shadowing.
18949 * buffer.c (fix_overlays_before): Mark locals as initialized.
18950 (fix_start_end_in_overlays): Likewise. This function should be
18951 simplified by using pointers-to-pointers, but that's a different
18953 (switch_to_buffer_1): Now static.
18954 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
18955 (report_overlay_modification): Rename locals to avoid shadowing.
18957 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
18958 Fix pointer signedness issue.
18959 (sys_subshell): Mark local as volatile if checking for lint,
18960 to suppress a gcc -Wclobbered warning that does not seem to be right.
18961 (MAXPATHLEN): Define only if needed.
18963 * process.c (serial_open, serial_configure): Move decls from here ...
18964 * systty.h: ... to here, so that they can be checked.
18966 * fns.c (get_random, seed_random): Move extern decls from here ...
18967 * lisp.h: ... to here, so that they can be checked.
18969 * sysdep.c (reset_io): Now static.
18970 (wait_for_termination_signal): Remove; unused.
18972 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
18973 (copy_keymap_item, append_key, push_text_char_description):
18975 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
18976 (DENSE_TABLE_SIZE): Remove; unused.
18977 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
18978 (describe_map_tree):
18979 Rename locals to avoid shadowing.
18981 * keyboard.c: Declare functions static if they are not used elsewhere.

19066 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
19067 These macros can no longer be used for assignment.

19128 For example, without this patch (encode-time 0 0 0 1 1
19129 1152921504606846976) returns the obviously-bogus value (-948597
19130 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
19131 reports time overflow. See
19132 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
19133 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
