3 Fix SIGDANGER handlers, for AIX (Bug#13408).
4 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
5 Move handlers here from emacs.c; they were out of place.
7 2013-01-05 Eli Zaretskii <eliz@gnu.org>
9 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
10 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
11 digits for buffer positions, before misalignment starts. Display
12 "0" for integer "object" field.
13 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
14 Display the newline glyph more unambiguously.
16 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
18 * nsterm.m (ns_draw_underwave):
19 * w32term.c (w32_draw_underwave):
20 * xterm.c (x_draw_underwave): Make underwave look more triangular
21 and also degrade gracefully for small fonts. (Bug#13000)
23 * nsterm.m (ns_draw_text_decoration):
24 * w32term.c (x_draw_glyph_string):
25 * xterm.c (x_draw_glyph_string): Don't use previous underline
26 thickness and position if previous underline type is underwave.
28 2012-12-31 Glenn Morris <rgm@gnu.org>
30 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
32 2012-12-29 Andreas Schwab <schwab@linux-m68k.org>
34 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
35 (LIBS_GNUSTEP): Define.
36 (LIBES): Add $(LIBS_GNUSTEP).
37 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
39 2012-12-27 Eli Zaretskii <eliz@gnu.org>
41 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
42 continuation glyph on a TTY with an indication of an empty line.
45 2012-12-27 Glenn Morris <rgm@gnu.org>
47 * cygw32.c (Fcygwin_convert_file_name_to_windows)
48 (Fcygwin_convert_file_name_from_windows): Doc fixes.
50 2012-12-24 Eli Zaretskii <eliz@gnu.org>
52 * fileio.c (file_name_as_directory, directory_file_name): Accept
53 an additional argument MULTIBYTE to indicate whether the input C
54 came from a multibyte or a unibyte Lisp string; all callers
55 adjusted. Don't assume the input string is always multibyte.
57 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
58 don't ENCODE_FILE them, and return a unibyte string if the input
60 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
61 don't assume the input strings will always be multibyte. If the
62 input strings are multibyte, decode strings obtained from C
65 2012-12-22 Martin Rudalics <rudalics@gmx.at>
67 * window.c (Fselect_window): Reword doc-string (Bug#13248).
69 2012-12-21 Eli Zaretskii <eliz@gnu.org>
71 * fileio.c (Finsert_file_contents): Doc fix.
73 * w32proc.c (new_child, delete_child, find_child_pid): For a
74 subprocess, consider its slot being in use as long as its process
75 handle (procinfo.hProcess) is not NULL. This avoids reusing the
76 slot when a new process is started immediately after killing
77 another one, without waiting enough time for the first process to
78 be reaped and resources allocated for it be orderly freed.
80 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
82 2012-12-21 Chong Yidong <cyd@gnu.org>
84 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
86 2012-12-15 Chong Yidong <cyd@gnu.org>
88 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
90 2012-12-14 Eli Zaretskii <eliz@gnu.org>
92 * w32.c (get_name_and_id): Always pass NULL as the first argument
93 of lookup_account_sid. Avoids crashes with UNC file names that
94 refer to DFS domains, not to specific machine names. (Bug#12621)
95 Remove now unused argument FNAME; all callers changed.
96 (get_file_owner_and_group): Remove now unused argument FNAME; all
99 2012-12-11 Eli Zaretskii <eliz@gnu.org>
101 * search.c (search_buffer): Check the inverse translations of each
102 character in pattern when the buffer being searched is unibyte.
105 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>
107 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
108 files, fixing a regression from 24.2.
109 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
111 2012-12-08 Jan Djärv <jan.h.d@swipnet.se>
113 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
115 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
117 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
118 DWORD_PTR, for compatibility with 64-bit builds.
120 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
121 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
122 (system_process_attributes): Use SIZE_T rather than DWORD, for
123 compatibility with 64-bit builds.
125 2012-12-08 Christopher Schmidt <christopher@ch.ristopher.com>
127 * lread.c (Vload_source_file_function): Doc fix (Bug#11647).
129 2012-12-07 Eli Zaretskii <eliz@gnu.org>
131 * indent.c (Fvertical_motion): If a display string will be
132 displayed on the left or the right margin, don't consider it as a
133 factor in cursor positioning. (Bug#13108)
135 2012-12-07 Martin Rudalics <rudalics@gmx.at>
137 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
139 2012-12-05 Eli Zaretskii <eliz@gnu.org>
141 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
142 fails, signal an error instead of continuing with an empty
144 Encode expanded temp file pattern before passing it to mkstemp or
147 2012-12-04 Eli Zaretskii <eliz@gnu.org>
149 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
150 Encode the file name before passing it to dostounix_filename, in
151 case it will downcase it (under w32-downcase-file-names).
154 2012-12-01 Chong Yidong <cyd@gnu.org>
156 * fileio.c (Vauto_save_list_file_name): Doc fix.
158 2012-11-30 Fabrice Popineau <fabrice.popineau@gmail.com>
160 * w32fns.c: Remove prototype of atof.
161 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
163 (file_dialog_callback): Declared UINT_PTR.
165 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
168 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
169 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
172 2012-11-27 Glenn Morris <rgm@gnu.org>
174 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
176 2012-11-26 Eli Zaretskii <eliz@gnu.org>
178 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
181 2012-11-24 Paul Eggert <eggert@cs.ucla.edu>
183 Revert recent change for Bug#8855.
184 As reported by Harald Hanche-Olsen in
185 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00445.html>
186 the change introduces a further bug, of creating lots of zombie
187 processes in some cases. Further work is needed to come up with a
188 better fix for Bug#8855.
190 2012-11-24 Eli Zaretskii <eliz@gnu.org>
192 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
193 highlighting on the frame was cleared. Prevents assertion
194 violations when repeatedly clicking on the "Top" link of the
195 "bread-crumbs" in Info buffers.
197 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
198 Eli Zaretskii <eliz@gnu.org>
200 Fix a race condition with glib (Bug#8855).
201 The symptom is a diagnostic "GLib-WARNING **: In call to
202 g_spawn_sync(), exit status of a child process was requested but
203 SIGCHLD action was set to SIG_IGN and ECHILD was received by
204 waitpid(), so exit status can't be returned." The diagnostic
205 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
206 The real bug is a race condition between Emacs and glib: Emacs
207 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
208 so that glib can't find it. Work around the bug by invoking
209 waitpid only on subprocesses that Emacs itself creates.
211 This is a backport from the trunk, consisting of:
213 * w32proc.c (create_child): Don't clip the PID of the child
214 process to fit into an Emacs integer, as this is no longer a
216 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
217 reaping only the process specified by PID argument, if that is
218 positive. Use PID instead of dead_child to know which process to
219 reap. Wait for the child to die only if WNOHANG is not in
221 (sys_select): Don't set dead_child.
223 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
224 as it is no longer needed.
226 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
228 (create_process, record_child_status_change): Don't use special
229 value -1 in pid field, as the caller now must know the pid rather
230 than having the callee infer it. The inference was sometimes
231 incorrect anyway, due to another race.
232 (create_process): Set new 'alive' member if child is created.
233 (process_status_retrieved): New function.
234 (record_child_status_change): Use it.
235 Accept negative 1st argument, which means to wait for the
236 processes that Emacs already knows about. Move special-case code
237 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
238 processes that have already been waited for, by testing and
239 clearing new 'alive' member. Remove the setting of
240 record_at_most_one_child for the !WNOHANG case.
241 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
242 now does this internally.
243 (handle_child_signal): Let record_child_status_change do all
244 the work, since we do not want to reap all exited child processes,
245 only the child processes that Emacs itself created.
246 * process.h (Lisp_Process): New boolean member 'alive'.
248 2012-11-23 Eli Zaretskii <eliz@gnu.org>
250 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
251 between bpos_covered and bpos_max. This fixes cursor display when
252 several display strings follow each other.
254 * .gdbinit (pgx): If the glyph's object is a string, display the
255 pointer to string data, rather than the value of the string object
256 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
258 2012-11-21 Eli Zaretskii <eliz@gnu.org>
260 * indent.c (Fvertical_motion): If the starting position is covered
261 by a display string, return to one position before that, to avoid
262 overshooting it inside move_it_to. (Bug#12930)
264 2012-11-20 Daniel Colascione <dancol@dancol.org>
266 * w32fns.c (Fx_file_dialog):
267 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
268 cygwin_convert_file_name*.
270 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
271 Rename cygwin_convert_path* to cygwin_convert_file_name*.
273 2012-11-20 Ken Brown <kbrown@cornell.edu>
275 * emacs.c (main): Set the G_SLICE environment variable for all
276 Cygwin builds, not just GTK builds. See
277 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
279 2012-11-19 Eli Zaretskii <eliz@gnu.org>
281 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Don't mix declaration of
282 w32_note_current_window with code. (Backport from trunk.)
284 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
285 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
286 Define for the MSVC compiler.
288 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing
291 2012-11-18 Eli Zaretskii <eliz@gnu.org>
293 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
294 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
295 dostounix_filename. Prevents crashes down the road, because
296 dostounix_filename assumes it gets a unibyte string. Reported by
297 Michel de Ruiter <michel@sentient.nl>, see
298 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
300 2012-11-17 Eli Zaretskii <eliz@gnu.org>
302 * w32select.c: Include w32common.h before w32term.h, so that
303 windows.h gets included before w32term.h uses some of its
306 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
308 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
310 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
312 2012-11-17 Jan Djärv <jan.h.d@swipnet.se>
314 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
315 (ns_select): Return at once if events are held (Bug#12834).
317 2012-11-16 enami tsugutomo <tsugutomo.enami@jp.sony.com>
319 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
320 Needed following 2012-10-20 change. (Bug#12902)
322 2012-11-16 Glenn Morris <rgm@gnu.org>
324 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
326 2012-11-15 Stefan Monnier <monnier@iro.umontreal.ca>
328 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
330 2012-11-14 Eli Zaretskii <eliz@gnu.org>
332 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
333 use the same value of thread handle.
334 (start_timer_thread): If the timer thread exited (due to error),
335 clean up by closing the two handles it used. Duplicate the caller
336 thread's handle here, so it gets duplicated only once, when
337 launching the timer thread. Set priority of the timer thread, not
339 (getitimer): Don't duplicate the caller thread's handle here.
342 2012-11-13 Jan Djärv <jan.h.d@swipnet.se>
344 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
347 2012-11-12 Eli Zaretskii <eliz@gnu.org>
349 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
350 passed to pint2str and pint2hrstr to be at most the size of the
351 frame's decode_mode_spec_buffer. This avoids crashes with very
352 large values of FIELD_WIDTH argument to decode_mode_spec.
355 2012-11-07 Martin Rudalics <rudalics@gmx.at>
357 * window.c (Fsplit_window_internal): Set combination limit of
358 new parent window to t iff Vwindow_combination_limit is t;
359 fixing a regression introduced with the change from 2012-09-22.
360 (Fwindow_combination_limit, Fset_window_combination_limit):
363 2012-11-06 Eli Zaretskii <eliz@gnu.org>
365 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
366 amount when the scroll margins are too large. When scrolling
367 backwards in the buffer, give up if cannot reach point or the
368 scroll margin within a reasonable number of screen lines.
369 Fixes point position in window under scroll-up/down-aggressively when
370 point is positioned many lines beyond the window top/bottom.
373 2012-11-05 Eli Zaretskii <eliz@gnu.org>
375 * ralloc.c (relinquish): If real_morecore fails to return memory
376 to the system, don't crash; instead, leave the last heap
377 unchanged and return. (Bug#12774)
379 2012-11-03 Eli Zaretskii <eliz@gnu.org>
381 * lisp.mk: Adjust comments to the fact that term/internal is now
382 loaded from loadup.el.
384 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
385 (msdos_fatal_signal): New function.
386 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
389 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
390 for GCC versions before 4.
391 (emacs_raise): Define to call msdos_fatal_signal.
393 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
394 iterator when starting in the middle of a display or overlay
397 2012-11-03 Jan Djärv <jan.h.d@swipnet.se>
399 * widget.c (resize_cb): New function.
400 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
401 (EmacsFrameResize): Check if all is up to date before changing frame
404 2012-11-01 Eli Zaretskii <eliz@gnu.org>
406 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
408 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
410 Fix crash when using Emacs as commit editor for git (Bug#12697).
411 * callproc.c (setpgrp): Remove macro, as we now use setpgid
412 and it is configured in conf_post.h.
413 (Fcall_process): Don't invoke both setsid and setpgid; the former
414 is enough, if it exists.
415 * callproc.c (Fcall_process, child_setup):
416 * process.c (create_process): Use setpgid.
417 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
419 * dispnew.c (init_display): Initialize the foreground group
420 if we are running a tty display.
421 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
422 * lisp.h (init_foreground_group): New decl.
423 * sysdep.c (inherited_pgroup): New static var.
424 (init_foreground_group, tcsetpgrp_without_stopping)
425 (narrow_foreground_group, widen_foreground_group): New functions.
426 (init_sys_modes): Narrow foreground group.
427 (reset_sys_modes): Widen foreground group.
429 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
431 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
433 2012-10-31 Martin Rudalics <rudalics@gmx.at>
435 * minibuf.c (read_minibuf): Restore current buffer since
436 choose_minibuf_frame calling Fset_frame_selected_window may
437 change it (Bug#12766).
439 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
441 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
443 2012-10-30 Kenichi Handa <handa@gnu.org>
445 * font.c (Ffont_at): If WINDOW is specified and it is not
446 displaying the current buffer, signal an error.
448 2012-10-29 Daniel Colascione <dancol@dancol.org>
450 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
451 In preparation for fixing bug#12739, move these functions from
454 * coding.h, coding.c: ... to here, and compile them only when
455 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
456 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
458 2012-10-28 Eli Zaretskii <eliz@gnu.org>
460 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
461 (timer_loop, getitimer, setitimer): Use it instead of
462 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
464 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
467 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
469 * nsterm.m (NO_APPDEFINED_DATA): New define.
470 (last_appdefined_event_data): New variable
471 (last_appdefined_event): Remove.
472 (ns_select): Initialize t from last_appdefined_event_data instead
473 of [last_appdefined_event data1].
474 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
475 remove last_appdefined_event (Bug#12698).
477 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
479 * frame.c (x_set_font): Catch internal error.
481 2012-10-27 Eli Zaretskii <eliz@gnu.org>
483 Avoid overflow in w32 implementation of interval timers.
484 When possible, for ITIMER_PROF count only times the main thread
486 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
487 'volatile ULONGLONG' types. All the other data which was
488 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
489 (GetThreadTimes_Proc): New typedef.
490 (w32_get_timer_time): New function, returns a suitable time value
492 (timer_loop): Enter critical section when accessing ULONGLONG
493 values of the itimer_data struct, as these accesses are no longer
494 atomic. Call 'w32_get_timer_time' instead of 'clock'.
495 Remove unused variable.
496 (init_timers): Initialize s_pfn_Get_Thread_Times.
497 (start_timer_thread): Don't assign itimer->caller_thread here.
498 (getitimer): Assign itimer->caller_thread here.
499 (setitimer): Always call getitimer to get the value of ticks_now.
500 (sys_spawnve): Avoid compiler warning about format mismatch.
502 2012-10-26 Eli Zaretskii <eliz@gnu.org>
504 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
505 mouse movement events if the menu bar is active. This avoids
506 producing a busy "hour-glass" cursor by Windows if the mouse
507 pointer is positioned over a tooltip shown for some menu item.
509 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
511 Don't assume process IDs fit in int.
512 * emacs.c (shut_down_emacs) [!DOS_NT]:
513 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
514 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
515 Use pid_t, not int, to store process IDs, as 'int'

1023 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1024 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
1025 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
1026 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
1027 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1028 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1029 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1030 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1031 now a supported configuration.
1033 * Makefile.in: consolidate image variables into LIBIMAGE; add
1034 W32_OBJ and W32_LIBS. Compile new files.
1037 (_DebPrint) declare tracing facility for W32 debugging. We need
1038 to unify tracing later.
1040 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1041 unconditional use of W32 Unicode functions. Cygwin runs only on
1042 100% Unicode operating systems.
1044 * cygw32.c: New file. Define Cygwin-specific facilities.
1045 (Fcygwin_convert_path_to_windows)
1046 (Fcygwin_convert_path_from_windows): New user functions for
1047 accessing Cygwin path-munging routines.
1049 * cygw32.h: New file.
1050 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1051 UTF-16LE strings temporarily inside non-Lisp-visible string
1054 (w32_strerror): Just what it says on the tin.
1056 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1057 also run for Cygwin; both systems have the same problem with using
1058 GUI facilities in a forked child. Also call syms_of_cygw32,
1059 syms_of_w32select in correct places.
1061 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1062 needs fork-then-exec for daemon launching.
1064 * font.h: Include frame.h.
1066 * image.c: Use the image library cache machinery only when we're
1067 compiling for native WINDOWSNT; Cygwin can use shared libraries
1068 like any other Unixlike system.
1070 * keyboard.c: Clarify a comment regarding the input loop.
1072 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1073 functions directly instead of trying to detect at runtime that our
1074 host operating system supports them. We make this change for two
1075 reasons: Cygwin lacks support for the multibyte character
1076 conversion functions used by the legacy menu code, and Cygwin
1077 never needs to rely on non-Unicode APIs.
1079 * unexw32.c (hinst): Declare extern.
1081 * w32.c: Change header order;
1082 (w32_strerror): Move to w32fns.c because we need it for
1083 non-WINDOWSNT builds.
1085 * w32.h: Add #error macro to make sure we don't include w32.h for
1086 Cygwin builds. Remove w32select declarations.
1088 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1089 w32fns.c. w32console.c is WINDOWSNT-only.
1091 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1092 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1094 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1095 (w32_major_version, w32_minor_version, w32_build_number)
1096 (os_subtype, sound_type): Define here
1097 (w32_defined_color): Make color parameter const for consistency
1098 with other _defined_color functions.
1099 (w32_createwindow): Unconditionally call w32_init_class instead of
1100 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1101 through the code is complex and unnecessary because class
1102 registration is practically free.
1103 (w32_name_of_message): New EMACSDEBUG-only function.
1104 (Fset_message_beep): Move here
1105 (Fx_open_connection): Require that the display name for Windows be
1106 "w32" for consistency, emacsclient disambiguation, and maybe, one
1107 day, multi-window-system support.
1108 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1109 Cygwin files for W32 GUI facilities, since these clearly don't
1110 expect Cygwin names.
1111 (_DebPrint): Define.
1112 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1113 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1114 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1115 (w32_last_error): Remove.
1117 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1119 * w32heap.c (syspage_mask): Declare here.
1120 (cache_system_info): Remove.
1122 * w32inevt.c (faked_key): Define globally, not statically.
1123 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1124 (w32_console_toggle_lock_key): Move to w32fns.c.
1126 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1128 * w32proc.c (_DebPrint): Move to w32fns.c.
1129 * w32select.c: Include string.h, stdio.h for Cygwin.
1130 * w32select.h: New File.
1132 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1134 (w32_message_fd): New variable. Under Cygwin, holds the file
1135 descriptor the system used to tell us about pending thread
1138 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1139 that prevented compilation under non-WINDOWSNT systems.
1141 (w32_initialize): Open /dev/windows and assign it to
1142 w32_message_fd. Provide w32 feature.
1144 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1145 (WM_EMACS_INPUT_READY): add.
1146 (prepend_msg, w32_message_fd): Declare globally.
1149 (keyboard_handle): Use only when WINDOWSNT.
1150 (notify_msg_ready): New function. Posts a message to the main
1151 thread's message queue under CYGWIN, which wakes up the main
1152 thread from select(2) by making the /dev/windows file descriptor
1153 ready. Under WINDOWSNT, it sets an event the same way the old
1156 (post, prepend_msg): Actually call notify_msg_ready instead of
1157 setting the input event directly.
1159 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1161 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1162 but it still has blocs in it, don't return it to the system,
1163 instead of aborting. (Bug#12402)
1165 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1167 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
1169 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
1170 MAC_OS_X_VERSION_10_6.
1171 (syms_of_nsterm): Remove comment about Panther and above for
1173 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
1174 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
1175 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
1177 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
1178 MAC_OS_X_VERSION_10_4.
1180 * nsmenu.m (fillWithWidgetValue:): Remove code for <
1181 MAC_OS_X_VERSION_10_2.
1183 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
1185 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
1186 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
1188 * nsterm.m (ns_in_resize): Remove (Bug#12479).
1189 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
1190 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
1191 Remove ns_in_resize check.
1192 (ns_clear_frame_area): Remove resize handle code.
1194 * nsfns.m (ns_in_resize): Remove.
1195 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
1196 Remove ns_in_resize check.
1198 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
1200 Improve sys_siglist detection.
1201 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
1202 defined as a macro, as is done in Solaris.
1203 (sys_siglist_entries): New macro.
1204 (save_strsignal): Use it.
1205 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1206 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1208 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1210 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1211 fullscreen/Fullscreen.
1213 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1214 tobar_height is new.
1216 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1217 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1218 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
1219 (windowDidResize:): Check for correct window if old style fullscreen.
1220 Capitalize word in comment. Remove incorrect comment.
1221 (initFrameFromEmacs:): tbar_height renamed tibar_height.
1222 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
1223 error in drawing background.
1224 (toggleFullScreen:): Remove comment. Rearrange calls.
1225 Set toolbar values to zero, save old height in tobar_height.
1226 Restore tool bar height when leaving fullscreen.
1227 (canBecomeMainWindow): New function.
1229 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
1231 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
1233 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1235 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1237 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1238 that time stamps of directories could also be changed.
1239 Don't request the too broad GENERIC_WRITE, only the more restrictive
1240 FILE_WRITE_ATTRIBUTES access rights.
1242 * fileio.c (Fset_file_times): Special-case ignoring errors for
1243 directories only on MSDOS, not on MS-Windows.
1245 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1247 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1249 2012-10-04 Eli Zaretskii <eliz@gnu.org>
1251 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
1252 see whether CreateFile failed.
1254 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1256 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1257 to avoid similar races.
1258 * keyboard.c (pending_signals): Now bool, not int.
1260 Port timers to OpenBSD, plus check for timer failures.
1261 OpenBSD problem reported by Han Boetes.
1262 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1264 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1265 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1266 like OpenBSD, which has timer_settime but does not declare it.
1267 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1268 whether to use itimerspec-related primitives. All uses of
1269 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1271 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1273 * profiler.c (handle_profiler_signal): Fix a malloc race
1274 that caused Emacs to hang on Fedora 17 when profiling Lisp.
1276 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
1278 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1280 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1282 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1283 consistent with the change in return value of 'safe_strsignal'.
1285 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1287 Prefer plain 'static' to 'static inline' (Bug#12541).
1288 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1289 (bidi_set_sor_type, bidi_push_embedding_level)
1290 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
1291 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
1292 (bidi_cache_search, bidi_cache_ensure_space)
1293 (bidi_cache_iterator_state, bidi_cache_find)
1294 (bidi_peek_at_next_level, bidi_set_paragraph_end)
1295 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1296 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1297 Now 'static', not 'static inline'.
1299 Count overruns when profiling; change units to ns.
1300 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1301 Give extra weight to samples after overruns, to attempt to count
1302 the time more accurately.
1303 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1304 the underlying primitives nominally do ns.
1305 (Fprofiler_cpu_start): Document the change. Mention that
1306 the sampling intervals are only approximate.
1308 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1310 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1312 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1313 case for the special 0 coding-system.
1315 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1316 (Fmake_overlay): Remove redundant tests.
1317 (fix_start_end_in_overlays): Remove redundant recentering.
1319 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1321 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1322 Update dependencies.
1324 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1326 Fix a malloc race condition involving strsignal.
1327 A signal can arrive in the middle of a malloc, and Emacs's signal
1328 handler can invoke strsignal, which can invoke malloc, which is
1329 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1330 Fix it by altering the signal handler so that it does not invoke
1332 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1333 * process.c (status_message): Use const pointer, in case strsignal
1334 is #defined to safe_strsignal.
1335 * sysdep.c (sys_siglist, init_signals): Always define and
1336 initialize a substitute sys_siglist if the system does not define
1337 one, even if HAVE_STRSIGNAL.
1338 (safe_strsignal): Rename from strsignal. Always define,
1339 using sys_siglist. Return a const pointer.
1340 * syssignal.h (safe_strsignal): New decl.
1341 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1343 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1345 * w32proc.c (timer_loop): Fix code that waits for timer
1346 expiration, to avoid high CPU usage.
1348 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1350 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1351 (sweep_weak_table): Remove redundant prototypes.
1353 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1355 * emacs.c: Move the inclusion of TERM_HEADER after including
1356 windows.h on WINDOWSNT. This avoids compilation problems with
1359 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1361 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1362 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1363 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1364 as the previous version used 'void *'.
1366 * ralloc.c (ROUNDUP): Fix last change.
1367 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1370 * w32proc.c <disable_itimers>: New static flag.
1371 (init_timers): Initialize it to zero, after creating the critical
1372 sections used by the timer threads.
1373 (term_timers): Set to 1 before deleting the critical sections.
1374 (getitimer, setitimer): If disable_itimers is non-zero, return an
1375 error indication without doing anything. Reported by Fabrice
1376 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1377 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1379 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1382 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1383 term_ntproc after all the other bookkeeping, to get timers working
1384 as long as possible.
1386 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1388 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1389 Suggested by Juri Linkov in
1390 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1392 Prefer plain 'static' to 'static inline' (Bug#12541).
1393 With static functions, modern compilers inline pretty well by
1394 themselves; advice from programmers often hurts as much as it helps.
1395 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1396 this change shrinks the text size of the Emacs executable by 1.1%
1397 without affecting CPU significantly in my benchmark.
1398 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

1696 for consistency with other handlers.
1697 (setup_cpu_timer): New function, with much of what used to be in

1699 Prefer timer_settime if available, and prefer
1700 thread cputime clocks, then process cputime clocks, then
1701 monotonic clocks, to the old realtime clock. Use make_timeval
1702 to round more-correctly when falling back to setitimer.
1703 (Fprofiler_cpu_start): Use it.
1704 (Fprofiler_cpu_stop): Prefer timer_settime if available.

1923 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1924 (interruptible_wait_for_termination):
1925 Move these decls from lisp.h to syswait.h, since they use pid_t.
1926 Needed on FreeBSD; see Herbert J. Skuhra in
1927 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1928 * callproc.c: Include syswait.h.
1930 gnutls.c, gtkutil.c: Use bool for boolean.
1931 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)
1932 (emacs_gnutls_handle_error):
1933 * gtkutil.c (xg_check_special_colors, xg_prepare_tooltip)
1934 (xg_hide_tooltip, xg_create_frame_widgets)

1942 (is_box_type, xg_tool_item_stale_p, xg_update_tool_bar_sizes)
1943 (update_frame_tool_bar, free_frame_tool_bar):
1944 * gtkutil.c, w32term.c, xterm.c (x_wm_set_size_hint):
1945 * nsmenu.m (ns_update_menubar):
1946 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
1947 * xfns.c (Fx_show_tip) [USE_GTK]:
1948 Use bool for boolean.
1949 * gtkutil.c (xg_update_frame_menubar):
1950 * xmenu.c (update_frame_menubar):
1951 Return void, not int, since caller ignores return value.
1952 * gtkutil.c (xg_change_toolbar_position):
1955 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1957 * makefile.w32-in (BLOCKINPUT_H): Remove.
1958 (SYSSIGNAL_H): New macro.

1974 2012-09-23 Eli Zaretskii <eliz@gnu.org>
1976 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
1977 fatal_error_backtrace.
1979 * w32proc.c (sys_kill): Undo last change: don't do anything when
1980 invoked to deliver SIGABRT to our own process. This is now
1981 handled by emacs_raise.
1983 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
1985 * w32term.c (w32_read_socket): Remove leftover reference to
1986 interrupt_input_pending.
1988 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1990 Do not use SA_NODEFER.
1991 Problem reported by Dani Moncayo in
1992 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
1994 * sysdep.c (emacs_abort): Do not reset signal handler.
1995 * emacs.c (terminate_due_to_signal): Reset signal handler here.
1996 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
1997 wanted even on POSIXish hosts, and it doesn't work on Windows.
1999 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2001 * xterm.c (x_term_init): Call fixup_locale before and after calling
2002 gtk_init (Bug#12392).
2004 2012-09-23 Chong Yidong <cyd@gnu.org>
2006 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2007 Vdynamic_library_alist.
2009 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2010 (Fgnutls_available_p): Caller changed.
2012 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2013 (Flibxml_parse_xml_region): Likewise.
2015 * dispextern.h (struct image_type): Remove arg from init function.
2017 * image.c (Finit_image_library, lookup_image_type)
2018 (define_image_type): Remove now-unneeded second arg.
2019 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2020 (init_tiff_functions, init_gif_functions, init_svg_functions):
2021 Arglist and w32_delayed_load calling convention changed.
2022 (gs_type): Remove init_gs_functions; there is no such function.
2023 (valid_image_p, make_image): Fix caller to lookup_image_type.
2025 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2027 Simplify and avoid signal-handling races (Bug#12471).
2029 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2030 Avoid recursive loop if there's a fatal error in the function itself.
2031 * atimer.c (pending_atimers):
2032 * blockinput.h: Don't include "atimer.h"; no longer needed.
2033 (interrupt_input_pending): Remove. All uses removed.
2034 pending_signals now counts both atimers and ordinary interrupts.
2035 This is less racy than having three separate pending-signal flags.
2036 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2038 Rename from their upper-case counterparts BLOCK_INPUT,
2039 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2040 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2041 This makes it easier to access volatile variables more accurately.
2042 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2043 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2044 that's more reliable if the code is buggy and sets
2045 interrupt_input_blocked to a negative value. All uses changed.
2046 * atimer.c (deliver_alarm_signal):
2047 Remove. No need to deliver this to the parent; any thread can
2048 handle this signal now. All uses replaced by underlying handler.
2049 * atimer.c (turn_on_atimers):
2050 * dispnew.c (handle_window_change_signal):
2051 * emacs.c (handle_danger_signal):
2052 * keyboard.c (kbd_buffer_get_event):
2053 Don't reestablish signal handler; not needed with sigaction.
2054 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2056 Rework to avoid unnecessary accesses to volatile variables.
2057 (UNBLOCK_INPUT_TO): Now a function.
2058 (totally_unblock_input, unblock_input): New decls.
2059 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2060 (init_data): Remove. Necessary stuff now done in init_signal.
2061 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2062 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2063 (fatal_error_code): Remove; no longer needed.
2064 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2065 it doesn't always backtrace. All uses changed. No need to reset
2066 signal to default, since sigaction and/or die does that for us now.
2067 Use emacs_raise (FOO), not kill (getpid (), FOO).
2068 (main): Check more-accurately whether we're dumping.
2069 Move fatal-error setup to sysdep.c
2070 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2071 * gtkutil.c (xg_get_file_name, xg_get_font):
2072 Remove no-longer-needed signal-mask manipulation.
2073 * keyboard.c, process.c (POLL_FOR_INPUT):
2074 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2075 * keyboard.c (read_avail_input): Remove.
2076 All uses replaced by gobble_input.
2077 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2078 (kbd_buffer_store_event_hold, gobble_input):
2079 (record_asynch_buffer_change) [USABLE_SIGIO]:
2080 (store_user_signal_events):
2081 No need to mess with signal mask.
2082 (gobble_input): If blocking input and there are terminals, simply
2083 set pending_signals to 1 and return. All hooks changed to not
2084 worry about whether input is blocked.
2085 (process_pending_signals): Clear pending_signals before processing
2086 them, in case a signal comes in while we're processing.
2087 By convention callers now test pending_signals before calling us.
2088 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2089 New functions, to support changes to blockinput.h.
2090 (handle_input_available_signal): Now extern.
2091 (reinvoke_input_signal): Remove. All uses replaced by
2093 (quit_count): Now volatile, since a signal handler uses it.
2094 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2095 All callers changed. Block SIGINT only if not already blocked.
2096 Clear sigmask reliably, even if Fsignal returns, which it can.
2097 Omit unnecessary accesses to volatile var.
2098 (quit_throw_to_read_char): No need to restore sigmask.
2099 * keyboard.c (gobble_input, handle_user_signal):
2100 * process.c (wait_reading_process_output):
2101 Call signal-handling code rather than killing ourselves.
2102 * lisp.h: Include <float.h>, for...
2103 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2104 (pending_signals): Now volatile.
2105 (syms_of_data): Now const if IEEE floating point.
2106 (handle_input_available_signal) [USABLE_SIGIO]:
2107 (terminate_due_to_signal, record_child_status_change): New decls.
2108 * process.c (create_process): Avoid disaster if memory is exhausted
2109 while we're processing a vfork, by tightening the critical section
2111 (send_process_frame, process_sent_to, handle_pipe_signal)
2112 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2114 (send_process): No need for setjmp/longjmp any more, since the
2115 SIGPIPE stuff is now gone. Instead, report an error if errno
2117 (record_child_status_change): Now extern. PID and W are now args.
2118 Return void, not bool. All callers changed.
2119 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2120 Remove. All uses removed. This bug should be fixed now in a
2122 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2123 and record the child status change directly. This avoids the
2124 need to futz with the signal mask.
2125 (process_fatal_action): Move here from emacs.c.
2126 (emacs_sigaction_flags): New function, containing
2127 much of what used to be in emacs_sigaction_init.
2128 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2129 caught by emacs, to make races less likely.
2130 (deliver_process_signal): Rename from handle_on_main_thread.
2132 (BACKTRACE_LIMIT_MAX): Now at top level.
2133 (thread_backtrace_buffer, threadback_backtrace_pointers):
2135 (deliver_thread_signal, deliver_fatal_thread_signal):
2136 New functions, for more-accurate delivery of thread-specific signals.
2137 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2138 (deliver_arith_signal): Handle in this thread, not
2139 in the main thread, since it's triggered by this thread.
2140 (maybe_fatal_sig): New function.
2141 (init_signals): New arg DUMPING so that we can be more accurate
2142 about whether we're dumping. Caller changed.
2143 Treat thread-specific signals differently from process-general signals.
2144 Block all signals while handling fatal error; that's safer.
2145 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2147 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2148 Ignore SIGPIPE unless batch.
2149 (emacs_backtrace): Output backtrace for the appropriate thread,
2150 which is not necessarily the main thread.
2151 * syssignal.h: Include <stdbool.h>.
2152 (emacs_raise): New macro.
2153 * xterm.c (x_connection_signal): Remove; no longer needed
2154 now that we use sigaction.
2155 (x_connection_closed): No need to mess with sigmask now.
2156 (x_initialize): No need to reset SIGPIPE handler here, since
2157 init_signals does this for us now.
2159 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2161 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2162 background rect may be larger (Bug#12245).
2164 2012-09-23 Chong Yidong <cyd@gnu.org>
2166 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2168 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2170 * .gdbinit: Just stop at fatal_error_backtrace.
2171 See Stefan Monnier's request in
2172 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2173 Remove no-longer-used query of system type.
2175 2012-09-22 Chong Yidong <cyd@gnu.org>
2177 * search.c (Freplace_match): Doc fix (Bug#12325).
2179 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2181 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2182 (Fline_end_position): Doc fix.
2184 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
2186 2012-09-22 Chong Yidong <cyd@gnu.org>
2188 * dispextern.h (struct image_type): Add new slot, storing a type
2189 initialization function.
2191 * image.c (define_image_type): Call the image initializer function
2192 if it is defined. Arguments and return value changed.
2193 (valid_image_p, make_image): Callers changed.
2194 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2195 (gif_type, imagemagick_type, svg_type, gs_type):
2196 Add initialization functions.
2197 (Finit_image_library): Call lookup_image_type.
2198 (CHECK_LIB_AVAILABLE): Macro deleted.
2199 (lookup_image_type): Call define_image_type here, rather than via
2200 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2201 (syms_of_image): Move define_image_type calls for xbm_type and
2202 pbm_type to lookup_image_type.
2204 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2206 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2207 'idle_timers' from here ...
2208 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2209 lists, to avoid infloops when the timer does something stupid,
2210 like reinvoke itself with the same or smaller time-out.
2213 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2215 * window.c (Fsplit_window_internal): Handle only Qt value of
2216 Vwindow_combination_limit separately.
2217 (Qtemp_buffer_resize): New symbol.
2218 (Vwindow_combination_limit): New default value.
2221 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2223 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
2224 the new overlay string. (Bug#10159)
2226 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2228 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2229 or that fprintf is async-signal-safe. POSIX doesn't require
2232 2012-09-22 Chong Yidong <cyd@gnu.org>
2234 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2237 2012-09-22 Kenichi Handa <handa@gnu.org>
2239 * composite.c (composition_reseat_it): Handle the case that a
2240 grapheme cluster is not covered by a single font (Bug#12352).
2242 2012-09-21 Chong Yidong <cyd@gnu.org>
2244 * image.c (define_image_type): Avoid adding duplicate types to
2245 image_types (Bug#12463). Suggested by Jörg Walter.
2247 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2249 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2250 (print_load_command_name): Add case LC_DATA_IN_CODE.
2251 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
2253 2012-09-21 Glenn Morris <rgm@gnu.org>
2255 * eval.c (Frun_hook_with_args_until_success)
2256 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2258 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2260 * fileio.c (Ffile_selinux_context): Only call freecon when
2261 lgetfilecon succeeded.
2262 (Fset_file_selinux_context): Likewise. (Bug#12444)
2264 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2266 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2267 reordering, locate the cursor by calling set_cursor_from_row; if
2268 that fails, clear the desired glyph matrix before returning a
2269 failure indication to the caller. Fixes leaving garbled display
2270 when fast scrolling with a down-key. (Bug#12403)
2271 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2272 scrolling through multibyte text.
2274 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2276 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2277 calling mark_vectorlike since that's the one that marks the window.
2278 (mark_discard_killed_buffers): Mark the final cdr.
2279 * window.h (struct window): Move prev/next_buffers to the
2280 non-standard fields.
2281 * window.c (make_window): Initialize prev/next_buffers manually.
2283 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2285 Omit unused arg EXPECTED from socket hooks.
2286 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2287 * nsterm.m (ns_term_init):
2288 * termhooks.h (struct terminal.read_socket_hook):
2289 * w32inevt.c (w32_console_read_socket):
2290 * w32term.c (w32_read_socket):
2291 * xterm.c (XTread_socket):
2292 Omit unused arg EXPECTED. All callers changed.
2293 (store_user_signal_events): Return void, not int, since callers no
2294 longer care about the return value. All uses changed.
2296 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2298 * w32gui.h (XParseGeometry): Do not declare.
2300 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2302 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2303 Ignore 'expected'. See Eli Zaretskii in
2304 <http://bugs.gnu.org/12471#8> (last line).
2306 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2307 (XParseGeometry): Now static. Substitute extremal values for
2308 values that are out of range.
2310 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2312 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2314 * nsfns.m (XParseGeometry): Remove.
2315 (Fx_create_frame): Call x_set_offset to correctly interpret
2316 top_pos in geometry.
2318 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2319 (Fx_parse_geometry): If there is a space in string, call
2320 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2322 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2324 * search.c (scan_buffer): Use character positions in calls to
2325 region_cache_forward and region_cache_backward, not byte
2326 positions. (Bug#12196)
2328 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2329 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2331 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2332 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2333 emacs_blocked_malloc, now deleted.
2335 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2337 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2338 The workaround was for improving performance on Solaris 2.4, but
2339 is getting in the way now. Emacs will still work if someone is
2340 still running Solaris 2.4 in a museum somewhere; Sun dropped
2341 support for Solaris 2.4 in 2003.
2342 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2343 * process.c (create_process) [HAVE_WORKING_VFORK]:
2344 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2345 since Emacs no longer uses vfork on that platform.
2347 2012-09-17 Glenn Morris <rgm@gnu.org>
2349 * emacs.c: Use COPYRIGHT.
2351 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2353 Remove configure's --without-sync-input option (Bug#12450).
2354 When auditing signal-handling in preparation for cleaning it up,
2355 I found that SYNC_INPUT has race conditions and would be a real
2356 pain to fix. Since it's an undocumented and deprecated
2357 configure-time option, now seems like a good time to remove it.
2358 Also see <http://bugs.gnu.org/11080#16>.
2359 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2360 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2361 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2362 (malloc_hysteresis):
2363 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2364 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2365 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2366 (dont_register_blocks, bytes_used_when_reconsidered)
2367 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2368 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2369 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2370 Remove. All uses removed.
2371 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2372 implementation, one that depends on whether the new macro
2373 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2375 * atimer.c (run_timers, handle_alarm_signal):
2376 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2377 (handle_async_input, process_pending_signals)
2378 (handle_input_available_signal, init_keyboard):
2379 * nsterm.m (ns_read_socket):
2380 * process.c (wait_reading_process_output):
2381 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2382 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2384 * xterm.c (XTread_socket):
2386 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2387 * eval.c (handling_signal): Remove. All uses removed.
2388 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2389 All uses replaced with the SYNC_INPUT version.
2390 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2392 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2395 * font.c (Ffont_shape_gstring): Remove unused local.
2397 2012-09-16 Glenn Morris <rgm@gnu.org>
2399 * Makefile.in (clean): No longer run nextstep's clean.
2401 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2403 (ns-app): Move here from ns.mk, and simplify.
2404 (clean): Simplify nextstep entry.
2405 * ns.mk: Remove file.
2407 2012-09-17 Kenichi Handa <handa@gnu.org>
2409 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2410 not covert the last few charactes.
2412 2012-09-16 Kenichi Handa <handa@gnu.org>
2414 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2415 here, but just check the validity of glyphs in the glyph-string.
2417 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2419 * window.c (Fwindow_parameter, Fset_window_parameter):
2420 Accept any window as argument (Bug#12452).
2422 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2424 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2425 to ns_term_init to avoid memory leak.
2427 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2428 explicit retain/release.
2429 (ns_term_init): Only allow one display. Initialize outerpool and
2432 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2434 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2435 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2436 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2437 the Microsoft problem in a different way, by altering ../nt/config.nt.
2439 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2454 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2455 by lisp.h. This completes removal of setjmp.h inclusion
2456 erroneously announced in the previous commit. (Bug#12446)
2458 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2461 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2462 not defined as a macro. The latter happens on MS-Windows.
2465 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2467 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2468 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2469 Some instances of '#include <setjmp.h>' removed, if the
2470 only reason for the instance was because "lisp.h" was included.
2471 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2472 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2473 and _longjmp with the new symbols. Emacs already uses _setjmp if
2474 available, so this change affects only POSIXish hosts that have
2475 sigsetjmp but not _setjmp, such as some versions of Solaris and
2476 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2477 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2478 (png_load_body) [HAVE_PNG]:
2479 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2480 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2481 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2482 since PNG requires jmp_buf. This is the only exception to the
2483 general rule that we now use sys_setjmp and sys_longjmp.
2484 This exception is OK since this code does not change the signal
2485 mask or longjmp out of a signal handler.
2487 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2489 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2490 Include "syssignal.h", for 'main_thread'.
2492 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2494 Avoid out-of-range marker position (Bug#12426).
2495 * insdel.c (replace_range, replace_range_2):
2496 Adjust markers before overlays, as suggested by comments.
2497 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2498 Remove redundant check before calling offset_intervals.
2500 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2502 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2503 current buffer (Bug#12387).
2505 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2507 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2509 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2511 Use a more backwards-compatible timer format (Bug#12430).
2512 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2513 vector element, not from the 4th, since PSECS is now at the end.
2514 (Fcurrent_idle_time): Doc fix.
2516 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2518 Function to mark objects and remove killed buffers at once.
2519 * alloc.c (discard_killed_buffers): Rename to ...
2520 (mark_discard_killed buffers) ... new name. Add marking
2521 of remaining objects. Fix comment. Adjust users.
2522 (mark_object): Do not touch frame buffer lists here.
2523 * frame.c (delete_frame): Reset frame buffer lists here.
2525 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2527 Better workaround for GNOME bug when --enable-gcc-warnings.
2528 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2529 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2530 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2532 Simplify SIGIO usage (Bug#12408).
2533 The code that dealt with SIGIO was crufty and confusing, e.g., it
2534 played tricks like "#undef SIGIO" but these tricks were not used
2535 consistently. Simplify mostly by not #undeffing standard symbols,
2536 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2537 or not as we please) rather than "defined SIGIO" (standard symbol
2538 that we probably shouldn't #undef).
2539 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2540 Modules that need it can include it.
2541 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2542 * dispextern.h (ignore_sigio): New decl.
2543 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2544 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2545 * emacs.c (shut_down_emacs):
2546 * keyboard.c (kbd_buffer_store_event_hold):
2547 Use ignore_sigio rather than invoking 'signal' directly.
2548 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2550 (FIONREAD, SIGIO): Do not #undef.
2551 (tty_read_avail_input): Use #error rather than a syntax error.
2552 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2553 for I_PIPE, used by SETUP_SLAVE_PTY.
2554 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2555 * sysdep.c (croak): Remove; no longer needed. This bit of
2556 temporary code, with Fred N. Fish's comment that it's temporary,
2557 has been in Emacs since at least 1992!
2558 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2559 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2560 * syssignal.h (croak): Remove decl.
2561 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2562 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2563 now that we're termios-only.
2564 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2565 * term.c (dissociate_if_controlling_tty): Use #error rather than
2568 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2569 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2570 to work around GNOME bug 683906.
2571 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2572 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2573 This works around GCC bug 54561.
2575 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2577 More fixes for 'volatile' and setjmp/longjmp.
2578 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2579 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2580 (png_load_body) [HAVE_PNG]:
2581 (jpeg_load_body) [HAVE_JPEG]:
2582 New function, with most of the old parent function's body.
2583 (png_load) [HAVE_PNG]:
2584 (jpeg_load) [HAVE_JPEG]:
2585 Invoke the new function, to avoid longjmp munging our locals.
2586 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2587 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2588 longjmp is passed 2, as the C standard doesn't guarantee this.
2589 Instead, store the failure code into mgr->failure_code.
2591 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2593 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2594 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2595 (syms_of_keyboard): Remove support for unread-command-char.
2597 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2599 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2600 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2601 violation. (Bug#12426)
2603 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2605 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2607 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2609 * eval.c: Add `inhibit-debugger'.
2610 (Qinhibit_debugger): New symbol.
2611 (call_debugger): Bind it instead of Qdebug_on_error.
2612 (maybe_call_debugger): Test Vinhibit_debugger.
2613 (syms_of_eval): Define inhibit-debugger.
2614 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2615 (syms_of_xdisp): Remove inhibit-debug-on-message.
2617 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2619 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2620 If a nonvolatile local variable is written before a _longjmp to
2621 the frame containing the variable, and is read after the _longjmp,
2622 the value read is indeterminate. Some local variables of type
2623 'struct handler' and 'struct catchtag' are used in this way, so
2624 mark each of their slots as volatile if the slot can be set before
2625 _longjmp and read afterwards.
2626 * lisp.h (struct handler): var and chosen_clause are now volatile.
2627 (struct catchtag): val, next, and pdlcount are now volatile.
2629 * bidi.c (bidi_push_it, bidi_pop_it):
2630 * fns.c (copy_hash_table):
2631 * image.c (define_image_type):
2632 * keyboard.c (kbd_buffer_store_event_hold):
2633 * process.c (Fprocess_send_eof):
2634 * xfaces.c (x_create_gc) [HAVE_NS]:
2635 * xgselect.c (xg_select):
2636 Prefer assignment to memcpy when either will do.
2638 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2639 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2640 time an item is removed. No need to mark this function 'inline';
2641 the compiler knows better than we do.
2643 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2645 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2646 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2647 to change_frame_size (Bug#12388).
2648 (windowDidResize:): Pass YES to updateFrameSize.
2650 * nsterm.h: Add delay parameter to updateFrameSize.
2652 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2654 Discard killed buffers from deleted window and frame objects.
2655 This reduces an amount of references to killed buffers and
2656 helps GC to reclaim them faster.
2657 * alloc.c (discard_killed_buffers): New function.
2658 (mark_object): Use it for deleted windows and frames.
2659 (mark_object): If symbol's value is set up for a killed buffer
2660 or deleted frame, restore its global binding.
2661 * data.c (swap_in_global_binding): Add GC notice.
2662 (swap_in_symval_forwarding): Use convenient set_blv_where.
2663 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2664 * window.h: ... to here.
2666 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2668 Convenient macro to check whether the buffer is live.
2669 * buffer.h (BUFFER_LIVE_P): New macro.
2670 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2671 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2673 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2675 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2676 composition cases (Bug#12364).
2678 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2679 overhang of succeeding glyphs overlapping box cursor.
2681 * w32term.c (x_draw_glyph_string): Likewise.
2683 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2685 Simplify, document, and port floating-point (Bug#12381).
2686 The porting part of this patch fixes bugs on non-IEEE platforms
2687 with frexp, ldexp, logb.
2688 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2690 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2691 support, by removing commented-out code and briefly listing the
2692 C89 functions excluded. The commented-out stuff was confusing
2693 maintenance, e.g., we thought we needed cbrt but it was commented out.
2694 (logb): Remove decl; no longer needed.
2695 (isfinite): New macro, if not already supplied.
2696 (isnan): Don't replace any existing macro.
2697 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2698 are present on all C89 platforms.
2699 (Ffrexp): Do not special-case zero, as frexp does the right thing
2701 (Flogb): Do not use logb, as it doesn't have the desired meaning
2702 on hosts that use non-base-2 floating point. Instead, stick with
2703 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2704 frexp, to avoid getting an unspecified result.
2706 * xdisp.c (Qinhibit_debug_on_message): Now static.
2708 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2710 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2711 NSBezierPath (Bug#12131).
2713 2012-09-10 Chong Yidong <cyd@gnu.org>
2715 * fns.c (Fdelq, Fdelete): Doc fix.
2717 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2719 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2720 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2722 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2724 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2725 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2728 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2730 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2731 left fringe if the window has a left margin. This avoids leaving
2732 traces of the cursor because its leftmost pixel is not drawn over.
2734 * dispnew.c (update_window_line): When the left margin area of a
2735 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2736 that screen line. (Bug#12277)
2738 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2740 Assume C89 or later for math functions (Bug#12381).
2741 This simplifies the code, and makes it a bit smaller and faster,
2742 and (most important) makes it easier to clean up signal handling
2743 since we can stop worring about floating-point exceptions in
2744 library code. That was a problem before C89, but the problem
2745 went away many years ago on all practical Emacs targets.
2746 * data.c, image.c, lread.c, print.c:
2747 Don't include <math.h>; no longer needed.
2748 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2749 might be autoconfigured, as that never happens.
2751 * doprnt.c (DBL_MAX_10_EXP):
2752 * print.c (DBL_DIG):
2753 Remove. C89 or later always defines these.
2754 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2755 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2756 (arith_error, domain_error, domain_error2):
2757 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2758 no longer needed -- we simply return what C returns. All uses removed.
2759 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2761 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2762 Remove. All uses expanded, as these macros are no longer used
2763 more than once and are now more trouble than they're worth.
2764 (Ftan): Use tan, not sin / cos.
2765 (Flogb): Assume C89 frexp.
2766 (fmod_float): Assume C89 fmod.
2767 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2768 (init_floatfns): Remove. All uses removed.
2770 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2772 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2773 compositeToPoint for OSX < 10.6 (Bug#12390).
2775 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2777 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2778 This produces more-accurate results.
2780 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2782 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2783 changes (Bug#12088).
2785 2012-09-08 Chong Yidong <cyd@gnu.org>
2787 * syntax.c (Fstring_to_syntax): Doc fix.
2789 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2791 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2792 in the internal border.
2793 (x_set_window_size): Remove static variables and their usage.
2794 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2795 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2796 Remove fringe/internal border adjustment (Bug#11052).
2797 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2798 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2799 (ns_fix_rect_ibw): Remove.
2800 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2801 (ns_dumpglyphs_box_or_relief): Ditto.
2802 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2804 (ns_dumpglyphs_image): Ditto.
2805 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2807 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2808 their usage. Add fringe_extended_p and its use as in other terms.
2809 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2810 scroll bar was removed.
2811 (updateFrameSize): New function.
2812 (windowDidResize): Move code to updateFrameSize and call it.
2814 * nsterm.h (EmacsView): Add updateFrameSize.
2816 2012-09-07 Chong Yidong <cyd@gnu.org>
2818 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2820 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2822 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2824 More signal-handler cleanup (Bug#12327).
2825 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2826 Problem introduced when merging patches. Noted by Eli Zaretskii in
2827 <http://bugs.gnu.org/12327#67>.
2828 * floatfns.c: Comment fix.
2829 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2830 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2831 and anyway the declaration is harmless even if SIGDANGER is not defined.
2832 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2833 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2834 source files not surprisingly expected syssignal.h to define, or
2835 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2836 Include <sys/ioctl.h>, for FIONREAD.
2837 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2838 This eliminates a problem whereby other files mysteriously had
2839 to include "syssignal.h" before including "systty.h" if they
2840 wanted to use "#ifdef SIGIO".
2842 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2844 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2846 * w32.c (sigemptyset): Empty the set.
2847 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2849 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2851 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2853 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2854 (mark_object): Likewise for frame objects.
2856 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2858 * syssignal.h (handle_on_main_thread): Always declare,
2859 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2860 This ports to platforms without HAVE_PTHREAD.
2862 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2864 Signal-handler cleanup (Bug#12327).
2865 Emacs's signal handlers were written in the old 4.2BSD style with
2866 sigblock and sigmask and so forth, and this led to some
2867 inefficiencies and confusion. Rewrite these to use
2868 pthread_sigmask etc. without copying signal sets around. Also,
2869 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2870 'signal', and instead use functions that do not attempt to take
2871 over the system name space. This patch causes Emacs's text
2872 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2873 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2874 Do not include <signal.h> or "syssignal.h", as these
2875 modules do not use signals.
2876 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2877 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2878 Do not include <signal.h>, as "syssignal.h" does that for us now.
2879 * atimer.c (sigmask_atimers): New function.
2880 (block_atimers, unblock_atimers): New functions,
2881 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2883 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2884 no longer needed here.
2885 * emacs.c (main): Inspect existing signal handler with sigaction,
2886 so that there's no need to block and unblock SIGHUP.
2887 * sysdep.c (struct save_signal): New member 'action', replacing
2888 old member 'handler'.
2889 (save_signal_handlers, restore_signal_handlers):
2890 Use sigaction instead of 'signal' to save and restore.
2891 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2892 New function. All users of 'signal' modified to use set_sighandler
2893 if they're writeonly, and to use sys_signal if they're read+write.
2894 (emacs_sigaction_init, forwarded_signal): New functions.
2895 (sys_signal): Remove. All uses replaced by calls to sigaction
2896 and emacs_sigaction_init, or by direct calls to 'signal'.
2897 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2898 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2899 all uses replaced by pthread_sigmask etc. calls.
2900 * syssignal.h: Include <signal.h>.
2901 (emacs_sigaction_init, forwarded_signal): New decls.
2902 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2903 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2904 (sigmask, sys_sigmask): Remove; no longer needed.
2905 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2906 (sigblock, sigunblock, sigfree):
2907 (sigsetmask) [!defined sigsetmask]:
2908 Remove. All uses replaced by pthread_sigmask.
2909 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2910 no longer need to be replaced, and its typical old uses
2911 are now done via emacs_sigaction_init and sigaction.
2912 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2913 (sys_sigdel): Remove; unused.
2914 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2916 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2918 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2919 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2921 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2923 Explicitly mark buffer_defaults and buffer_local_symbols.
2924 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2925 mark_local_symbols here.
2926 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2927 since special buffers aren't marked here any more.
2928 (allocate_buffer): Chain new buffer with all_buffers here...
2929 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2931 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2932 (syms_of_buffer): Remove staticpro of the above.
2933 (init_buffer_once): Set names for buffer_defaults and
2934 buffer_local_symbols.
2936 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2938 Use bool for booleans in font-related modules.
2939 * font.c (font_intern_prop, font_style_to_value)
2940 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
2941 (generate_otf_features, font_check_otf_features, font_check_otf)
2942 (font_match_p, font_list_entities, font_at):
2943 * fontset.c (fontset_id_valid_p, reorder_font_vector
2944 (fontset_find_font, Fset_fontset_font)
2945 (face_suitable_for_char_p) [0]:
2946 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
2947 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
2948 (m17n_flt_initialized, ftfont_shape_by_flt):
2949 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
2950 * nsfont.m (nsfont_draw):
2951 * w32font.c (w32font_draw):
2952 * w32term.c (x_draw_glyphless_glyph_string_foreground):
2953 Use bool for booleans.
2954 * font.h: Adjust to above API changes.
2955 (struct font, struct font_driver, struct font_driver_list):
2956 Use bool for booleans.
2957 (struct font): Remove useless member encoding_type.
2959 * fontset.c, xftfont.c: Omit unnecessary static decls.
2961 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2963 * alloc.c (mark_object): Revert window marking code
2964 since it's unsafe for the Fset_window_configuration.
2966 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
2968 Fix race conditions with signal handlers and errno (Bug#12327).
2969 Be more systematic about preserving errno whenever a signal
2970 handler returns, even if it's not in the main thread. Do this by
2971 renaming signal handlers to distinguish between signal delivery
2972 and signal handling. All uses changed.
2973 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
2974 * data.c (deliver_arith_signal): Rename from arith_error.
2975 * dispnew.c (deliver_window_change_signal): Rename from
2976 window_change_signal.
2977 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
2978 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
2979 * keyboard.c (deliver_input_available_signal): Rename from
2980 input_available_signal.
2981 (deliver_user_signal): Rename from handle_user_signal.
2982 (deliver_interrupt_signal): Rename from interrupt_signal.
2983 * process.c (deliver_pipe_signal): Rename from send_process_trap.
2984 (deliver_child_signal): Rename from sigchld_handler.
2985 * atimer.c (handle_alarm_signal):
2986 * data.c (handle_arith_signal):
2987 * dispnew.c (handle_window_change_signal):
2988 * emacs.c (handle_fatal_signal, handle_danger_signal):
2989 * keyboard.c (handle_input_available_signal):
2990 * keyboard.c (handle_user_signal, handle_interrupt_signal):
2991 * process.c (handle_pipe_signal, handle_child_signal):
2992 New functions, with the actual signal-handling code taken from the
2993 original respective signal handlers, sans the sporadic attempts to
2994 preserve errno, since that's now done by handle_on_main_thread.
2995 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
2996 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
2997 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2999 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3000 Move initialization of main_thread to sysdep.c's init_signals.
3001 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3002 our usage, and simplifies the mainline code.
3003 (record_child_status_change): New static function, as a helper
3004 for handle_child_signal, and with most of the old child handler's
3006 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3007 (handle_child_signal): Use the above.
3008 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3009 Moved here from emacs.c.
3010 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3011 code moved here from emacs.c's main function.
3012 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3013 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3014 This lets callers save and restore errno properly.
3016 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3018 Remove redundant or unused things here and there.
3019 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3020 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3021 * editfns.c (Fcompare_buffer_substrings): Likewise.
3022 * frame.h (struct terminal, struct font_driver_list):
3023 Remove redundant declarations.
3024 * window.h (Qleft, Qright): Likewise.
3026 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3028 Do not mark objects from deleted buffers, windows and frames.
3029 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3030 (mark_object): Likewise for windows and frames.
3032 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3034 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3035 buffer_defaults and buffer_local_symbols as valid objects.
3036 Return special value to denote them.
3038 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3040 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3041 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3042 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3043 (file_name_absolute_p, Fsubstitute_in_file_name):
3044 (check_executable, check_writable, Ffile_accessible_directory_p)
3045 (Fset_file_selinux_context, Fdefault_file_modes)
3046 (Finsert_file_contents, choose_write_coding_system)
3047 (Fwrite_region, build_annotations, a_write, e_write)
3049 * filelock.c (boot_time_initialized, get_boot_time)
3050 (get_boot_time_1, lock_file_1, within_one_second):
3051 * floatfns.c (in_float):
3052 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3053 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3054 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3055 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3056 * window.c (compare_window_configurations):
3057 Use bool for booleans.
3058 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3059 (Fdefault_file_modes): Now mode_t, not int, for modes.
3060 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3061 (internal_delete_file): Now returns void, not a (boolean) int,
3062 since nobody was looking at the return value.
3063 * lisp.h, window.h: Adjust to above API changes.
3065 * xdisp.c (set_message): Simplify and reindent last change.
3067 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3069 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3071 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3073 * eval.c (call_debugger): Make the function non-static so that we
3074 can call it from set_message.
3076 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3077 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3079 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3081 Give more-useful info on a fatal error (Bug#12328).
3082 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3083 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3084 of doing the work ourselves.
3085 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3086 do most of the work.
3087 (fatal_error_backtrace): New function, taken from the guts
3088 of the old fatal_error_signal, but with a new option to output
3090 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3091 info about the signal than just its number.
3092 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3093 * sysdep.c: Include <execinfo.h>
3094 (emacs_backtrace): New function, taken partly from the previous
3095 code of the 'die' function.
3096 (emacs_abort): Call fatal_error_backtrace rather than abort.
3098 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3100 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3101 eager (load-time) macro-expansion.
3102 * lisp.mk (lisp): Add macroexp.
3104 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3106 Simplify redefinition of 'abort' (Bug#12316).
3107 Do not try to redefine the 'abort' function. Instead, redo
3108 the code so that it calls 'emacs_abort' rather than 'abort'.
3109 This removes the need for the NO_ABORT configure-time macro
3110 and makes it easier to change the abort code to do a backtrace.
3111 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3112 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3113 Remove; sysdep.c's emacs_abort now takes its place.
3114 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3115 'abort' changed to use 'emacs_abort'.
3116 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3117 (abort) [!defined abort]: Rename to ...
3118 (emacs_abort): ... new name.
3119 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3120 the place of the old 'abort' in emacs.c.
3121 * w32.c, w32fns.c (abort): Do not #undef.
3122 * w32.c (emacs_abort): Rename from w32_abort.
3124 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3126 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3127 offsets[j].dv, since the y axis of the screen coordinates points
3128 down, while the y axis of the font definition coordinates points
3129 up. This fixes display of Arabic diacritics such as KASRA and
3130 KASRATAN. (Bug#11860)
3132 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3134 Be more systematic about _setjmp vs setjmp.
3135 * alloc.c (test_setjmp, mark_stack):
3136 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3137 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3138 (png_load, my_error_exit, jpeg_load):
3139 * process.c (send_process_trap, send_process):
3140 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3141 The underscored versions are up to 30x faster on some hosts.
3142 Formerly, the code used setjmp+longjmp sometimes and
3143 _setjmp+_longjmp at other times, with no particular reason to
3144 prefer setjmp+longjmp.
3146 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3148 Fix minor problem found by static checking.
3149 * buffer.c (Fdelete_all_overlays): Return nil.
3151 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3153 * buffer.c (Fdelete_all_overlays): New function.
3155 2012-09-03 Chong Yidong <cyd@gnu.org>
3157 * gtkutil.c: Add extern decl for Qxft.
3159 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3161 * emacs.c, eval.c: Use bool for boolean.
3162 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3163 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3164 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
3165 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
3166 (main, decode_env_path, Fdaemon_initialized):
3167 * eval.c (call_debugger, Finteractive_p, interactive_p):
3168 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
3169 (maybe_call_debugger, Fbacktrace):
3170 * process.c (read_process_output, exec_sentinel):
3171 Use bool for booleans.
3172 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3173 All callers changed.
3174 * eval.c (interactive_p): Omit always-true boolean argument
3175 EXCLUDE_SUBRS_P. All callers changed.
3176 * dispextern.h, lisp.h: Reflect above API changes.
3177 * firstfile.c (dummy): Use the address of 'main', whose signature
3178 won't change, instead of the address of 'initialize', whose
3179 signature just changed from int to bool.
3180 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
3181 * msdos.c (fatal_error_in_progress): ... from here.
3182 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
3184 (redisplay_internal, unwind_redisplay): Simply clear
3185 REDISPLAYING_P when unwinding, instead of saving its previous,
3186 always-false value and then restoring it.
3188 Clean up some extern decls.
3189 Mostly, this hoists extern decls out of .c files and into .h files.
3190 That way, we're more likely to catch errors if the interfaces change.
3191 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
3192 declare xg_mark_data.
3193 * dispextern.h (x_frame_parm_handlers):
3195 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
3196 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
3197 (Qultra_bold, Qoblique, Qitalic):
3198 Move extern decl here from .c file.
3199 * alloc.c (xg_mark_data) [USE_GTK]:
3201 * eval.c (Qlexical_binding):
3202 * fns.c (time) [!HAVE_UNISTD_H]:
3203 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
3204 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
3205 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
3206 * lread.c (Qinternal_interpreter_environment):
3207 * minibuf.c (Qbuffer):
3208 * process.c (QCfamily, QCfilter):
3209 * widget.c (free_frame_faces):
3210 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
3211 * xfont.c (x_clear_errors):
3212 * xterm.c (x_frame_parm_handlers):
3213 Remove now-redundant extern decls.
3214 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
3215 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
3217 * xfaces.c: Remove unnecessary static decls.
3218 * xterm.c (updating_frame): Remove decl of nonexistent object.
3220 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
3221 when building globals.h, as the objects that are not built on
3222 this host are not needed to compile C files on this host.
3224 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>

3278 offset adjustment values separately for each cluster. (Bug#11860)
3280 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3281 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3282 about implicit conversions from integer to pointer.

3340 window system declarations.
3342 * frame.h: Move common functions here: set_frame_menubar,
3343 x_set_window_size, x_sync, x_get_focus_frame,

3402 for GCC 4.7.1 x86-64.
3404 2012-08-30 Glenn Morris <rgm@gnu.org>
3406 * lread.c (init_lread): For out-of-tree builds, only add the
3407 source directory's site-lisp dir to the load-path if it exists,
3408 consistent with in-tree builds. (Bug#12302)
3410 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

3640 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3641 are all boolean, so make them single-bit bitfields.
3643 * lisp.h (ASET): Remove attempt to detect side effects.
3644 It was meant to be temporary and it often doesn't work,
3645 because when IDX has side effects the behavior of IDX==IDX
3646 is undefined. See Stefan Monnier in
3647 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

3655 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3657 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3658 as that's faster and simpler than static storage. Don't bother
3659 with the g_main_context_query overhead if g_main_context_pending
3660 says no events are pending.
3661 (gfds, gfds_size): Remove these static vars.
3662 (xgselect_initialize): Remove; no longer needed.
3663 All uses and decls removed.

3677 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3679 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3681 On assertion failure, print backtrace if available.
3682 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3683 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3684 * Makefile.in (LIB_EXECINFO): New macro.
3687 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3688 * bytecode.c (exec_byte_code):
3689 * callint.c (check_mark, Fcall_interactively):
3690 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3691 (getenv_internal, sync_process_alive, call_process_exited):
3692 * lisp.h (USE_SAFE_ALLOCA):
3693 Use bool for booleans, instead of int.
3694 * lisp.h, process.h: Adjust prototypes to match above changes.
3695 * callint.c (Fcall_interactively): Don't assume the mark's
3696 offset fits in 'int'.
3698 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3700 * buffer.c, buffer.h: Use bool for boolean.
3701 * buffer.c (reset_buffer_local_variables)
3702 (buffer_lisp_local_variables, Fset_buffer_modified_p)
3703 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
3704 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
3705 (overlay_touches_p, overlay_strings, Foverlay_put)
3706 (report_overlay_modification, call_overlay_mod_hooks):
3707 (mmap_enlarge, mmap_set_vars):
3708 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3709 Use bool for booleans, instead of int.
3710 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3711 since the 1-or-0 return value is always ignored anyway.
3712 (mmap_initialized_p):
3713 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3714 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3716 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3718 * bidi.c: Use bool for boolean.
3719 This is a bit more readable, and makes the text segment of bidi.o
3720 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3721 Presumably it's faster too.
3722 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3724 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3725 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
3726 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
3727 (bidi_explicit_dir_char, bidi_level_of_next_char)
3728 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3729 Use bool for booleans, instead of int.
3730 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3731 (bidi_unshelve_cache): Adjust decls to match code.
3733 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3735 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3738 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3740 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3741 * atimer.h: Include <stdbool.h>.
3743 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3745 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3746 compile time tests instead of run time tests on systems that do
3748 (FRAME_MAC_P): Remove leftover from deleted code.
3749 * frame.c (syms_of_frame): Remove leftover from deleted code.
3751 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3753 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3755 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3757 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3758 Otherwise, the compiler complains about (A?B:C) where B is void
3759 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3760 (fontset_add): Return void, for FONTSET_ADD.
3762 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3764 * alloc.c: Use bool for booleans.
3765 (gc_in_progress, abort_on_gc)
3766 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3767 (dont_register_blocks) [GC_MALLOC_CHECK]:
3768 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3769 (check_string_bytes, make_specified_string, memory_full)
3770 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3771 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3772 (mark_stack, valid_pointer_p, make_pure_string)
3773 (Fgarbage_collect, survives_gc_p, gc_sweep):
3774 Use bool for booleans, instead of int.
3775 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3776 Remove unused local.
3777 * alloc.c (PURE_POINTER_P):
3778 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3779 * editfns.c (Fformat):
3780 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3782 * fns.c (sweep_weak_table):
3783 * lisp.h (suppress_checking, push_message, survives_gc_p)
3784 (make_pure_string, gc_in_progress, abort_on_gc):
3785 * lread.c (readchar, read1):
3786 * print.c (Fprin1_to_string):
3787 * xdisp.c (push_message):
3788 Use bool for booleans affected directly or indirectly by
3791 Make recently-introduced setters macros.
3792 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3793 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3794 (set_fontset_default, set_fontset_fallback): Rename from their
3795 upper-case counterparts, and make them functions rather than macros.
3796 This is more consistent with the other recently-introduced setters.
3797 These don't need to be inline, since they're local.
3799 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3801 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3802 the loop (Bug#12247).
3804 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3806 * lisp.h (vcopy): Use memcpy rather than our own loop.
3807 This fixes a performance regression introduced by the recent
3808 addition of vcopy. This means 'vcopy' will need to be modified
3809 for a copying collector, but that's OK. Also, tighten the
3810 checking in the assertion.
3812 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3814 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3815 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3816 non-base glyph for the width of the base character, according to
3817 what x_draw_composite_glyph_string_foreground expects.
3818 Generate WADJUST value according to composition_gstring_width's
3819 expectations, to produce correct width of the composed character.
3820 Reverse the sign of the DU offset produced by ScriptPlace.
3822 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3824 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3826 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3828 Avoid direct writes to contents member of struct Lisp_Vector.
3829 * lisp.h (vcopy): New function to copy data into vector.
3830 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3831 * fns.c (Ffillarray): Use ASET.
3832 * keyboard.c (timer_check_2): Use AREF and ASET.
3833 (append_tool_bar_item, Frecent_keys): Use vcopy.
3834 * lread.c (read_vector): Use ASET.
3835 * msdos.c (Frecent_doskeys): Use vcopy.
3836 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3837 (Finternal_merge_in_global_face): Use ASET and vcopy.

3843 the position of its buffer's point.
3844 (Fset_window_point): For the selected window always go in its
3845 buffer to the specified position.
3847 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3849 Setter macros for fontsets.
3850 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3851 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3852 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3855 2012-08-20 Glenn Morris <rgm@gnu.org>
3857 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3858 Don't assume that `ln -f' works.
3860 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3862 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3863 and later about non-assignments with no effect. See discussion at
3864 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3867 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3869 Inline setter functions for Lisp_Objects slots of struct specbinding.
3870 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3873 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3875 * window.c (select_window): Always make selected window's buffer
3878 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3880 Use AREF and ASET for docstrings of category tables.
3881 * category.h (CATEGORY_DOCSTRING): Use AREF.
3882 (SET_CATEGORY_DOCSTRING): Use ASET.
3883 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3885 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3887 Inline setter functions for hash table members.
3888 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3889 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3890 (set_hash_key_and_value, set_hash_index, set_hash_next)
3891 (set_hash_hash): New functions.
3892 * charset.c, fns.c: Adjust users.
3894 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3896 Inline getter and setter functions for per-buffer values.
3897 * buffer.h (per_buffer_default, set_per_buffer_default)
3898 (per_buffer_value, set_per_buffer_value): New functions.
3899 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
3900 * buffer.c, data.c: Adjust users.
3902 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3904 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3906 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3908 Rely on <config.h> + <unistd.h> to declare 'environ',
3909 as gnulib does this if the system doesn't.
3910 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3911 Remove declaration. MS-Windows declares it on stdlib.h which is
3912 included by conf_post.h.
3913 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3914 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
3915 * vm-limit.c: Include <unistd.h>, for 'environ'.
3917 * unexaix.c, unexcoff.c: Include "mem-limits.h".
3918 (start_of_data): Remove decl; mem-limits.h provides it.
3920 * xdisp.c (handle_invisible_prop): Make it a bit faster
3921 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3923 2012-08-19 Chong Yidong <cyd@gnu.org>
3925 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
3928 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
3930 * .gdbinit: Use call instead of set when calling a function in the
3933 * data.c (set_internal): Don't use set_blv_found.
3934 (Fkill_local_variable): Likewise.
3936 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
3938 * nsfont.m (ns_ascii_average_width): Ensure the string
3939 ascii_printable is initialized with a null-terminated character
3940 array. Otherwise, it can contain undesired extra characters.
3942 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
3944 port new setting code to Sun C 5.8 2005/10/13
3945 * chartab.c, lisp.h (char_table_set, char_table_set_range):
3946 Return void, not Lisp_Object. Otherwise, the compiler
3947 complains about (A?B:C) where B is void and C is Lisp_Object
3948 when compiling CHAR_TABLE_SET, due to the recent change to
3949 the API of sub_char_table_set_contents.
3951 2012-08-18 Chong Yidong <cyd@gnu.org>
3953 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
3954 for the string case (Bug#3874).

4781 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
4782 * w32.c (init_environment): Change the default values of many
4783 environment variables in dflt_envvars[] to NULL, to avoid pushing
4784 them into environment when they were not already defined.
4785 Remove the code that deletes site-lisp subdirectories from the default
4786 value of EMACSLOADPATH, as it is no longer needed.
4787 (check_windows_init_file): Now external, not static.
4788 Use Vload_path as is, without adding anything, as this function is now
4789 called when Vload_path is already set up.
4791 * w32.h (check_windows_init_file): Add prototype.
4793 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

4800 installation tree, as appropriate.
4802 * callproc.c (init_callproc_1): Call decode_env_path instead of
4803 doing its equivalent by hand.

4805 the code that sets Vexec_path run on MS-Windows.
4807 * lread.c (init_lread): Add comments to #ifdef's.
4809 * msdos.c (dos_set_window_size, IT_update_begin)

4836 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
4837 Remove unnecessary pointer casts.
4838 * alloc.c (record_xmalloc): New function.
4839 * lisp.h (record_xmalloc): New decl.
4840 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4841 more like a function. This is because the pointer cast is not
4842 needed. All uses changed.
4843 * print.c (print_string, print_error_message): Avoid length recalc.
4845 Improve fix for macroexp crash with debugging (Bug#12118).
4846 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4847 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4848 not supposed to be invoked from the garbage collector.

4850 (gc_aset): New function, which is like ASET but can be
4851 used in the garbage collector.

4875 (sys_rename): Diagnose renaming of a symlink when the user doesn't
4876 have the required privileges.
4877 (get_file_security_desc_by_name): Rename from

4880 with addition of handling of symlinks and support for 'lstat'.
4881 If possible, get file's attributes and security information by
4882 handle, not by name. Produce S_IFLNK bit for symlinks, when
4883 called from 'lstat'.
4884 (stat, lstat): New functions, call 'stat_worker'.
4885 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4886 symlinks when the underlying filesystem supports them.
4888 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4890 Fix macroexp crash on Windows with debugging (Bug#12118).
4891 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4892 checking subscripts; problem introduced with the recent
4893 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4894 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4895 since it's used in non-static inline functions now.
4897 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
4898 Don't assume buffer size fits in 'int'. Remove unused local.

4918 * composite.c (COMPOSITE_INLINE):
4919 * dispnew.c (DISPEXTERN_INLINE):
4920 * sysdep.c (SYSTIME_INLINE):
4921 Define to EXTERN_INLINE, so that the corresponding functions
4922 are compiled into code.
4923 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
4924 (INLINE_HEADER_END): New macros.
4925 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

4945 hard-coding the path separator.
4947 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
4949 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
4950 This how ASET and AREF are supposed to work, and makes
4951 it easier to think about future improvements. See
4952 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
4953 * charset.h (set_charset_attr): New function.

5441 Fix export of symbols to GDB (Bug#12036).
5442 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
5443 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5444 emacs.c, as this is a more-suitable home. Had this been done earlier
5445 the fix for 12036 would have avoided some of the problems noted in
5446 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5447 would have been more obvious.
5448 * emacs.c: Do not include <verify.h>; no longer needed.
5449 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5450 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5451 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5452 Remove; now done in lisp.h.
5453 * lisp.h (PUBLISH_TO_GDB): New macro.
5454 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
5455 (DATA_SEG_BITS): Use it.
5456 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
5457 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5458 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5459 not be usable in #if. This simplifies things.
5461 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5463 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
5465 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
5467 Simplify export of symbols to GDB (Bug#12036).
5468 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5469 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5470 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5471 Adjust to changes in lisp.h and emacs.c, by using
5472 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5473 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5474 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5475 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5476 instead of gdb_valbits.
5477 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5478 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5479 instead of gdb_array_mark_flag.
5480 (xboolvector): Get size from $->size, not $->header.size.
5481 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5482 (xreload, hook-run, hookpost-run): Remove.
5483 * emacs.c: Include <verify.h>.
5484 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5485 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5487 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5488 (gdb_USE_LSB_TAG): New enum constants.
5489 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5490 Also define these as enum constants, so they're visible to GDB.
5491 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5492 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5493 as constants, so they're visible to GDB.
5494 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
5495 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
5496 Now enum constants, not macros, so they're visible to GDB.
5497 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5498 more convenient now. All uses changed.
5499 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5500 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5502 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
5504 Explicitly free restriction data that are not needed anymore.
5505 * editfns.c (save_restriction_restore): Free restriction data.
5507 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
5509 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5510 add argument, tune behavior, and adjust all callers.
5512 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5514 Use typedef for EMACS_INT, EMACS_UINT.
5515 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5516 than macros. This simplifies debugging in the usual case, since
5517 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5518 and it allows expressions involving EMACS_INT casts.
5519 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5521 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
5523 * nsterm.m (ns_read_socket): Return early if there is a modal

5529 that FOCUS-FRAME can be omitted.
5531 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5533 Adjust buffer text indirection counters at the end of Fkill_buffer.
5534 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5535 buffer is definitely dead. This should really fix an issue reported
5536 by Christoph Scholtes again. (Bug#12007).
5537 (init_buffer_once): Initialize indirection counters of
5538 buffer_defaults and buffer_local_symbols (for sanity and safety).
5540 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5542 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5543 and continuation glyphs on tooltip frames, leave them at zero.
5544 Avoids continued lines in tooltips. (Bug#11832)
5546 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
5548 Simplify copy_overlay.
5549 * buffer.c (copy_overlay): Simplify. Use build_marker.

5552 2012-07-23 Eli Zaretskii <eliz@gnu.org>
5554 * print.c (print_object): Don't crash when a frame's name is nil
5555 or invalid. (Bug#12025)
5557 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
5558 it signals an error when a tooltip frame is being created.
5560 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5562 Cleanup miscellaneous objects allocation and initialization.
5563 * alloc.c (allocate_misc): Change to static. Add argument to
5564 specify the subtype. Adjust comment and users.
5565 (build_overlay): New function.
5566 * buffer.c (copy_overlays, Fmake_overlay): Use it.
5567 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.

5569 (build_overlay): Add prototype.
5571 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5573 Swap buffer text indirection counters in Fbuffer_swap_text.
5574 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5575 This avoids crash reported by Christoph Scholtes at
5576 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5578 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5580 * nsmenu.m (Popdown_data): New struct.
5581 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
5583 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

5585 and autorelease them. Also autorelease img and matrix (Bug#12005).
5586 (dealloc): Remove (Bug#12005).

5599 (live_buffer, set_marker_internal): New function.
5600 (Fset_marker, set_marker_restricted): Use set_marker_internal.

5603 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
5605 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
5606 as it's limited by the amount of memory, not by INT_MAX.
5608 2012-07-21 Eli Zaretskii <eliz@gnu.org>
5610 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
5611 in special-event-map. See the discussion at

5692 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
5693 'for_each_per_buffer_object_at'.

5746 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
5748 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug

5759 than doing the check by hand with an abort ().
5761 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
5763 * eval.c (Fdefvar): Don't check constants since we only set the var if
5764 it's not yet defined anyway (bug#11904).
5766 * lisp.h (last_undo_boundary): Declare new var.
5767 * keyboard.c (command_loop_1): Set it.
5768 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
5769 were auto-added by the command loop (bug#11774).
5771 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>

6339 The functional style also makes code easier to read and maintain.
6340 * systime.h: Include <sys/time.h> on all hosts, not just if
6341 WINDOWSNT, since 'struct timeval' is needed in general.
6342 (EMACS_TIME): Now a typedef, not a macro.
6343 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
6345 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
6346 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
6347 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
6348 (EMACS_TIME_LE): Now functions, not macros.
6349 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
6350 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
6351 which are not functions. All uses rewritten to use:
6352 (make_emacs_time): New function.
6353 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
6354 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
6355 not functions. All uses rewritten to use the following, respectively:
6356 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
6357 (add_emacs_time, sub_emacs_time): New functions.
6358 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
6359 * fileio.c (Fcopy_file):
6360 * xterm.c (XTflash): Get the current time closer to when it's used.
6361 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

6368 * frame.c (Fmake_terminal_frame):
6369 * gtkutil.c (get_utf8_string):
6371 * nsmenu.m (ns_update_menubar):
6372 * regex.c (regerror):
6373 Prefer memcpy to strncpy and strncat when either will do.

6375 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
6376 (menu_separator_name_p):
6377 * nsmenu.m (ns_update_menubar):
6378 Prefer memcmp to strncmp when either will do.
6379 * nsterm.m: Include <ftoastr.h>.
6381 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6382 Prefer snprintf to strncpy.
6383 * nsterm.m (ns_term_init):
6384 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6385 * nsterm.m (ns_term_init):
6386 Avoid the need for strncpy, by using build_string or
6387 make_unibyte_string directly. Use dtoastr, not snprintf.
6388 * process.c (Fmake_network_process): Diagnose service names that
6389 are too long, rather than silently truncating them or creating
6390 non-null-terminated names.
6391 (Fnetwork_interface_info): Likewise, for interface names.
6392 * sysdep.c (system_process_attributes) [GNU_LINUX]:
6393 Prefer sprintf to strncat.
6394 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
6395 Prefer vsnprintf to vsprintf + strncpy.
6397 2012-07-10 Glenn Morris <rgm@gnu.org>
6399 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
6400 Clarify fallback case.
6402 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6404 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
6405 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
6406 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
6407 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
6408 where argument type is known to be a Lisp_Cons.
6410 2012-07-10 Tom Tromey <tromey@redhat.com>

6420 Optimize pure C strings initialization.
6421 * lisp.h (make_pure_string): Fix prototype.
6422 (build_pure_c_string): New function, defined as static inline. This
6423 provides a better opportunity to optimize away calls to strlen when
6424 the function is called with compile-time constant argument.
6425 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
6426 argument, adjust users accordingly. Use build_pure_c_string where
6428 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
6429 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
6430 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
6432 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6434 Avoid calls to strlen in miscellaneous functions.
6435 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
6436 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
6437 * lread.c (openp): Likewise.
6439 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6441 Avoid calls to strlen in path processing functions.
6442 * fileio.c (file_name_as_directory): Add comment. Change to add
6443 srclen argument and return the length of result. Adjust users
6445 (directory_file_name): Fix comment. Change to add srclen argument,
6446 swap 1st and 2nd arguments to obey the common convention.
6447 Adjust users accordingly.
6448 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
6450 2012-07-10 Glenn Morris <rgm@gnu.org>
6452 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
6453 Move PENDING_OUTPUT_COUNT definition to configure.
6455 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
6456 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
6457 * s/gnu.h (DATA_START): Move definitions to configure.
6459 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
6460 We include usg5-4-common.h, which defines them both.
6462 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
6463 O_RDONLY already includes it).
6465 Stop ns builds setting the EMACSLOADPATH environment variable.
6466 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6467 Now it does not set EMACSLOADPATH, just returns the load-path string.
6468 * nsterm.h: Update accordingly.
6469 * lread.c [HAVE_NS]: Include nsterm.h.
6470 (init_lread) [HAVE_NS]: Use ns_load_path.
6471 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
6473 2012-07-09 Glenn Morris <rgm@gnu.org>
6475 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
6476 since the included bsd-common.h does so.
6478 Stop ns builds setting the EMACSPATH environment variable.
6479 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
6480 (ns_init_paths): Do not set EMACSPATH.
6481 * nsterm.h (ns_exec_path): Add it.
6482 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
6485 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
6487 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
6489 * process.c (wait_reading_process_output): 'waitchannels' was unset
6490 when read_kbd || !NILP (wait_for_cell); fix this.
6492 Add GCC-style 'const' attribute to functions that can use it.
6493 * character.h (char_resolve_modifier_mask):
6494 * keyboard.h (make_ctrl_char):
6495 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
6496 (init_character_once, next_almost_prime, init_fns, init_image)
6497 (flush_pending_output, init_sound):
6498 * mem-limits.h (start_of_data):
6499 * menu.h (finish_menu_items):

6502 Declare the dummy function with ATTRIBUTE_CONST.
6503 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
6504 Add decls with ATTRIBUTE_CONST.
6506 Minor improvements to make_formatted_string.
6507 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
6508 where int is good enough, as vsprintf returns an int.
6509 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
6511 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6513 Use make_formatted_string to avoid double length calculation.
6514 * lisp.h (make_formatted_string): New prototype.
6515 * alloc.c (make_formatted_string): New function.
6516 * buffer.c (Fgenerate_new_buffer_name): Use it.
6517 * dbusbind.c (syms_of_dbusbind): Likewise.
6518 * editfns.c (Fcurrent_time_zone): Likewise.
6519 * filelock.c (get_boot_time): Likewise.
6520 * frame.c (make_terminal_frame, set_term_frame_name)
6521 (x_report_frame_params): Likewise.
6522 * image.c (gs_load): Likewise.
6523 * minibuf.c (get_minibuffer): Likewise.

6538 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6540 Move marker debugging code under MARKER_DEBUG.
6541 * marker.c (MARKER_DEBUG): Move marker debugging code under
6542 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6543 for bootstrap with --enable-checking (~3x slowdown reported
6544 by Juanma Barranquero <lekktu@gmail.com>).
6545 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6547 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6549 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6550 See <http://bugs.gnu.org/11825#29>.
6552 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6554 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6555 has no font, use the frame's font. (Bug#11813)
6556 (display_line): Add commentary about displaying truncation glyphs
6558 (produce_special_glyphs): Move here from term.c.
6560 * term.c (produce_special_glyphs): Move to xdisp.c.
6562 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6565 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6567 * xdisp.c (display_line): Avoid warning about implicit declaration
6570 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6572 * lisp.h: Remove empty conditional.
6574 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6576 * lread.c (load_path_check): Now static.
6578 Fix some minor --with-ns problems found by static checking.
6579 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6580 (x_set_font) [!HAVE_X_WINDOWS]:
6581 * image.c (xpm_load_image) [HAVE_NS]:
6582 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6583 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6584 Remove unused local.
6585 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6586 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6587 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6588 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6589 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6590 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6591 Fix pointer signedness problem.
6592 * xfaces.c (FRAME_X_FONT_TABLE):
6593 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6595 2012-07-07 Glenn Morris <rgm@gnu.org>
6597 * lread.c (load_path_check): New function, split from init_lread.
6598 (init_lread): Reorganize. Motivation:
6599 If EMACSLOADPATH is set, check/warn about that rather than the
6600 defaults, which we are not going to use. Hence we can remove
6601 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6602 Don't warn if site-lisp directories are missing.
6603 If not installed, start from a blank load-path, since
6604 PATH_LOADSEARCH refers to the eventual installation directories.
6606 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6608 Support truncation and continuation glyphs on GUI frames, when
6609 fringes are disabled. (Bug#11832)
6610 * xdisp.c (init_iterator): Get dimensions of truncation and
6611 continuation glyphs even if on GUI frames.
6612 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6613 or both, are absent.
6614 (start_display, move_it_in_display_line_to): Handle the case of a
6615 GUI frame without a fringe to display continuation or truncation
6617 (insert_left_trunc_glyphs): Support GUI frames: make sure
6618 truncation glyphs overwrite enough glyphs from the current line to
6619 have sufficient space in pixels.
6620 (display_line): Support truncation and continuation glyphs on GUI
6621 frames. If some spare pixels are left on the line after inserting
6622 the truncation glyphs, fill that space with a stretch glyph of a
6623 suitably computed width.
6625 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6626 produce_glyphs, to support GUI sessions.
6628 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6630 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6632 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6634 Do not require float-time's arg to fit in time_t (Bug#11825).
6635 This works better on hosts where time_t is unsigned, and where
6636 float-time is applied to the (negative) difference between two times.
6637 * editfns.c (decode_time_components): Last arg is now double *,
6638 not int *, and means to store all the result as a double, without
6639 worrying about whether the seconds part fits in time_t.
6640 All callers changed.
6641 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6642 All callers changed.
6643 (Ffloat_time): Do not fail merely because the specified time falls
6644 outside of time_t range.
6646 2012-07-07 Glenn Morris <rgm@gnu.org>
6648 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
6649 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
6650 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
6652 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
6654 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
6655 Update dependencies.
6657 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6659 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6661 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
6662 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
6663 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6664 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6665 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6666 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6668 * xfont.c (compare_font_names): Redo to omit the need for casts.
6670 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6672 * xfns.c (Fx_change_window_property): Doc fix.
6673 * w32fns.c (Fx_change_window_property): Doc fix.
6675 * w32fns.c (Fx_window_property): Accept the same arguments as the
6676 X Windows version. Doc fix.
6677 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6679 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6680 Eli Zaretskii <eliz@gnu.org>
6682 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6683 Windows-specific code from nt/config.nt moved here.
6684 Obsolete settings removed.
6686 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6688 * process.c: Avoid unnecessary calls to gettime.
6689 (wait_reading_process_output): Don't get the time of day
6690 when gobbling data immediately and not waiting, as there's no need
6691 for it in that case. This removes a FIXME.
6693 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6695 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6696 is defined (Bug#11768).
6698 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6700 Fix marker debugging code.
6701 * marker.c (byte_char_debug_check): Do not perform the check
6702 if buffer is not multibyte.
6703 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6704 Call byte_char_debug_check with correct arguments.
6706 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6708 Compile marker debugging code only if ENABLE_CHECKING is defined.
6709 * marker.c (byte_char_debug_check, count_markers):
6710 Use only if ENABLE_CHECKING is defined.
6711 (byte_debug_flag): Remove.
6712 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6713 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6715 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6717 Avoid code repetition in marker-related functions.
6718 * marker.c (attach_marker): New function.
6719 (Fset_marker, set_marker_restricted, set_marker_both)
6720 (set_marker_restricted_both): Use it.
6721 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6722 Consistently rename charno to charpos.
6723 (marker_position): Add eassert.
6724 (marker_byte_position): Convert to eassert.
6726 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6728 Simplify list operations in unchain_overlay and unchain_marker.
6729 * buffer.c (unchain_overlay): Simplify. Add comment.
6730 * marker.c (unchain_marker): Simplify. Fix comments.
6732 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

6742 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6743 * window.c (save_window_save): Likewise.
6745 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6747 Do not use Fdelete_overlay in delete_all_overlays
6748 to avoid redundant calls to unchain_overlay.
6749 * buffer.c (drop_overlay): New function.
6750 (delete_all_overlays, Fdelete_overlay): Use it.
6751 * minibuf.c (get_minibuffer): Fix comment.
6753 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6755 Port to OpenBSD 5.1 amd64.
6756 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6757 This is needed for OpenBSD, and should be harmless on all BSD systems.
6758 Also, include <sys/sysctl.h>, as it should be available on all
6759 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6760 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6761 use p_pid member, not kp_proc.pid.
6763 2012-07-06 Glenn Morris <rgm@gnu.org>
6765 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6767 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6769 More xmalloc and related cleanup.
6770 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
6771 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
6772 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

6778 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6780 Omit needless casts involving void * pointers and allocation.
6781 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6782 as the former is more robust if P's type is changed.
6783 Prefer xzalloc to xmalloc + memset 0.
6784 Simplify malloc-or-realloc to realloc.
6785 Don't worry about xmalloc returning a null pointer.
6786 Prefer xstrdup to xmalloc + strcpy.
6787 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6789 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6790 alloca of a constant.
6792 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6794 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6795 hscroll is larger than the line width. Fixes long and futile
6796 looping inside extend_face_to_end_of_line (on a TTY) producing
6797 glyphs that are not needed and thrown away.
6799 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6801 * marker.c (set_marker_restricted_both): Simplify by using

6806 * editfns.c (region_limit): Simplify by using clip_to_bounds.
6808 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
6810 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
6811 not defined (Bug#11768).
6812 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
6813 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6814 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6815 followed by gtk_box_set_homogeneous (Bug#11768).
6816 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6817 (update_theme_scrollbar_width, xg_create_scroll_bar):
6818 Use gtk_scrollbar_new (Bug#11768).
6819 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.

6827 * xdisp.c (window_hscroll_limited): New function.
6828 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6829 coordinates when window's hscroll is set to insanely large
6832 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6834 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

6896 Problem reported by Troels Nielsen in
6897 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

6901 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6902 This should be fixed in a better way; see Eli Zaretskii in
6903 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6904 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6906 * fileio.c (time_error_value): Rename from special_mtime.
6907 The old name's problems were noted by Eli Zaretskii in
6908 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6910 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6911 This variable's comment says Emacs needs at least one GDB-visible
6912 symbol of type enum pvec_type, to work around GDB problems.
6913 The symbol's value doesn't matter.
6915 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6916 that causes compilation to fail on pre-C99 compilers.
6918 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6920 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

6926 headers for buffer_defaults and buffer_local_symbols.
6927 Reported by Juanma Barranquero <lekktu@gmail.com>.
6929 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6931 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6932 * lisp.h (enum pvec_type): Use fewer bits.
6933 (PSEUDOVECTOR_SIZE_BITS): New constant.
6934 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6935 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6936 change in pvec_type.
6937 (PSEUDOVECTOR_TYPEP): New macro.
6938 (TYPED_PSEUDOVECTORP): Use it.
6939 * fns.c (internal_equal): Adapt code to extract pvectype.

6943 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
6944 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
6945 (sweep_vectors): Use it. Use local var `total_bytes' instead of
6946 abusing vector->header.next.nbytes.
6947 (live_vector_p): Use PVEC_TYPE.
6948 (mark_object): Adapt code to extract pvectype. Use switch.
6950 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6952 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
6953 Tighten new eassert a bit.
6955 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6957 Fix compilation with --enable-gcc-warnings and -O1
6959 * doprnt.c (doprnt): Change type of tem to int, initialize
6960 to avoid compiler warning. Add eassert.
6961 * search.c (simple_search): Initialize match_byte to avoid
6962 compiler warning. Add eassert.
6964 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6966 Avoid weird behavior with large horizontal scrolls.
6967 Without this change, for example, large hscroll values would
6968 mess up Emacs's display on Fedora 15 x86, presumably due to
6969 overflows in int calculations in the display code.
6970 Also, if buffers had long lines, Emacs would freeze.
6971 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
6972 (set_window_hscroll): New function, containing the old guts of
6973 Fset_window_hscroll. Return the clipped value.
6974 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
6975 This avoids the need to check against PTRDIFF_MAX.
6977 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
6979 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6981 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
6983 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6985 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
6986 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
6987 since GCC 4.4.6 issues a bogus warning for them.
6989 Fix bugs in file timestamp newness comparisons.
6990 * fileio.c (Ffile_newer_than_file_p):
6991 * lread.c (Fload): Use full timestamp resolution of files,
6992 not just the 1-second resolution, so that files that are only
6993 slightly newer still count as newer.
6994 * fileio.c (Ffile_newer_than_file_p): Don't assume file
6995 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
6997 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
6999 * fileio.c: Improve handling of file time marker. (Bug#11852)
7000 (special_mtime): New function.
7001 (Finsert_file_contents, Fverify_visited_file_modtime):
7002 Use it to set special mtime values consistently.
7004 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7006 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7007 marker for non-existing file. (Bug#11852)
7009 2012-07-03 Glenn Morris <rgm@gnu.org>
7011 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7012 and did not make it into globals.h).
7014 2012-07-03 Tom Tromey <tromey@redhat.com>
7016 * window.c (Fset_window_margins, Fset_window_fringes)
7017 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
7018 * textprop.c (Fprevious_property_change): No longer static.
7019 * syntax.c (Fsyntax_table_p): No longer static.

7047 * w32term.h: Remove EXFUNs.
7048 * window.h: Remove EXFUNs.

7050 * xterm.h: Remove EXFUN.
7052 2012-07-03 Glenn Morris <rgm@gnu.org>
7054 * lisp.h (Frandom): Make it visible to C.
7055 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7056 buffer for invisible buffers. (Bug#1229)
7058 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7060 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7061 values which aren't power of 2.
7062 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7063 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7066 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7068 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7070 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7072 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7074 * alloc.c (allocate_vector_block): Remove redundant
7075 calls to mallopt if DOUG_LEA_MALLOC is defined.
7076 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7077 avoid calls to mallopt if zero_vector is returned.
7079 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7081 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7082 is enabled, avoid dereferencing NULL current_sblock if
7085 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7087 Cleanup basic buffer management.
7088 * buffer.h (struct buffer): Change layout to use generic vector
7089 marking code. Fix some comments. Change type of 'clip_changed'
7090 to bitfield. Remove unused #ifndef old.
7091 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7092 (GET_OVERLAYS_AT): Fix indentation.
7093 (for_each_per_buffer_object_at): New macro.
7094 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

7096 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
7097 * alloc.c (allocate_buffer): Adjust to match new layout of
7098 struct buffer. Fix comment.
7099 (mark_overlay): New function.

7101 Lisp area of struct buffer.
7102 (mark_object): Use it. Adjust marking of misc objects
7103 and related comments.
7105 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7107 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7108 wrapper that is not needed because the wrapped code is a no-op (zero
7109 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7110 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7112 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7114 * alloc.c (mark_buffer): Simplify. Remove prototype.
7115 (mark_object): Add comment. Reorganize marking of vector-like
7116 objects. Use CHECK_LIVE for all vector-like objects except buffers
7117 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7118 Avoid redundant calls to mark_vectorlike for bool vectors.
7120 2012-06-30 Glenn Morris <rgm@gnu.org>
7122 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7124 * epaths.in (PATH_SITELOADSEARCH): New.
7125 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7126 This is rather than relying on --enable-locallisppath elements
7127 having "site-lisp" in their names. (Bug#10208#25, 11658)
7129 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7131 * w32proc.c (sys_select): Accept and ignore one more argument.
7133 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7135 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7136 (pselect) [!MS_DOS]: Redirect to sys_select.
7138 * sysdep.c: Don't include dos.h and dosfns.h.
7140 * process.c (sys_select):
7141 * msdos.c (sys_select): Accept one more argument and ignore it.
7143 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7144 adapt data types and code to that.
7147 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7148 which clashes with the gnulib function of the same name.
7150 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7152 * font.c (font_style_to_value, font_style_symbolic)
7153 (font_prop_validate_style): Add type checks for values in
7156 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7158 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7161 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7163 * xdisp.c (try_window_id): Undo last change.
7165 * w32.c (getwd): Adjust commentary about startup_dir.
7166 (init_environment): Always call sys_access, even in non-MSVC
7167 builds. Don't chdir to the directory of the Emacs executable.
7168 This undoes code from 1997 which was justified by the need to
7169 "avoid conflicts when removing and renaming directories". But its
7170 downside was that every relative file name was being interpreted
7171 relative to the directory of the Emacs executable, which can never
7172 be TRT. In particular, it broke sys_access when called with
7173 relative file names.
7174 (sys_access): Map GetLastError to errno.
7176 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7178 * window.h (struct window): Change type of 'fringes_outside_margins'

7182 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7185 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
7187 * gnutls.c (emacs_gnutls_handshake):
7188 Add QUIT to make the loop interruptible.
7190 2012-06-29 Glenn Morris <rgm@gnu.org>
7192 * charset.c (init_charset): Make lack of etc/charsets fatal.
7194 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7196 * editfns.c (region_limit): Fix type mismatch.
7198 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7200 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
7201 undefined. Convert from xassert to eassert.
7202 * nsmenu.m: Convert from xassert to eassert.
7203 * nsterm.m: Likewise.
7205 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
7207 * editfns.c (region_limit): Clip to narrowing (bug#11770).
7209 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
7211 Avoid integer overflow on scroll-left and scroll-right.
7212 * window.c (HSCROLL_MAX): New macro.
7213 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
7214 overflow when requested scroll falls outside ptrdiff_t range.
7216 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7218 * window.h (struct window): Change type of 'hscroll',
7219 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
7220 'last_modified' and 'last_overlay_modified' to EMACS_INT.
7221 Adjust users accordingly.
7222 * xdisp.c (try_cursor_movement): Replace type check with eassert.
7223 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
7224 from EMACS_INT to ptrdiff_t.
7225 (make_window): Omit redundant initialization.
7227 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
7229 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
7231 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7233 * window.h (struct window): Change type of 'use_time' and
7234 'sequence_number' from Lisp_Object to int.
7235 * frame.c (make_frame): Adjust users accordingly.
7236 * print.c (print_object): Likewise.
7237 * window.c (select_window, Fwindow_use_time, make_parent_window)
7238 (make_window): Likewise.
7240 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
7242 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
7243 enabled with --enable-checking=[all,glyphs] configure option.
7244 Fix GLYPH_DEBUG usage assuming that it may be undefined,
7245 adjust comments accordingly.
7246 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
7247 undefined, adjust comments accordingly.

7368 Use sprintf return value instead of invoking strlen on result.
7369 In the old days this wasn't portable, since some sprintf
7370 implementations returned char *. But they died out years ago and
7371 Emacs already assumes sprintf returns int.
7372 Similarly for float_to_string.
7373 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

7381 Use sprintf or float_to_string result to avoid need to call strlen.
7382 * data.c (Fnumber_to_string):
7383 Use make_unibyte_string, since the string must be ASCII.
7384 * lisp.h, print.c (float_to_string): Now returns int length.
7385 * term.c (produce_glyphless_glyph):
7386 Use sprintf result rather than recomputing it.
7388 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

7421 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

7426 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7427 instead of truncating it to 63 (admittedly a generous limit).

7487 * keyboard.c (kbd_buffer_get_event):
7488 * process.c (Faccept_process_output):

7557 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7559 Support higher-resolution time stamps (Bug#9000).
7560 The time stamps are only nanosecond-resolution at the C level,
7561 since that's the best that any real-world system supports now.
7562 But they are picosecond-resolution at the Lisp level, as that's
7563 easy, and leaves room for future OS improvements.
7565 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7568 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7569 Don't get current time unless it's needed.
7571 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7572 now provides it if it's absent.
7573 (start_atimer): Port to higher-res time stamps.
7574 Check for time stamp overflow. Don't get current time more
7575 often than is needed.
7577 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7578 Include systime.h, not time.h.
7579 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7581 * dired.c: Include stat-time.h.
7582 (Ffile-attributes): File times now have higher resolution.
7584 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
7585 (struct image): Timestamp now has higher resolution.
7587 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7588 has at least microseconds now. All uses removed.
7589 (update_frame, update_single_window, update_window, update_frame_1)
7590 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7591 (duration_to_sec_usec): Remove; no longer needed.
7593 * editfns.c (time_overflow): Now extern.
7594 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
7595 (float-time, Fformat_time_string, Fcurrent_time_string)

7599 (decode_time_components, lisp_seconds_argument): New functions.
7600 (make_time): Now static.
7601 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7602 Report an error if the time is invalid, rather than having the caller
7605 * fileio.c: Include <stat-time.h>
7606 (Fcopy_file): Copy higher-resolution time stamps.
7607 Prefer to set the time stamp via a file descriptor if that works.

7609 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7610 (Fvisited_file_modtime, Fset_visited_file_modtime):
7611 Support higher-resolution time stamps.
7613 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7615 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7617 * image.c (prepare_image_for_display, clear_image_cache)
7618 (lookup_image): Port to higer-resolution time stamps.
7620 * keyboard.c (start_polling, bind_polling_period):
7621 Check for time stamp overflow.
7622 (read_char, kbd_buffer_get_event, timer_start_idle)
7623 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7624 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7625 Port to higher-resolution time stamps. Do not assume time_t is signed.
7626 (decode_timer): New function. Timers are now vectors of length 9,
7627 not 8, to accommodate the picosecond component.
7628 (timer_check_2): Use it.
7630 * nsterm.m (select_timeout, timeval_subtract): Remove.
7631 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7632 as they're a bit more accurate and handle overflow better.
7633 (ns_select): Change prototype to be compatible with pselect.
7634 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7635 * nsterm.h (ns_select): Adjust prototype.
7637 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7638 us-resolution time stamps.
7639 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7641 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7643 * lisp.h (time_overflow): New decl.
7644 (wait_reading_process_output): First arg is now intmax_t, not int,
7645 to accommodate larger waits.
7647 * process.h (struct Lisp_Process.read_output_delay):
7648 Now counts nanoseconds, not microseconds.
7649 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7651 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7652 (wait_reading_process_output):
7653 Port to ns-resolution time stamps.
7654 (Faccept_process_output, wait_reading_process_output):
7655 Check for time stamp overflow. Do not assume time_t is signed.
7656 (select_wrapper): Remove; we now use pselect.
7657 (Fprocess_attributes): Now generates ns-resolution time stamps.
7659 * sysdep.c: Include utimens.h. Don't include utime.h
7660 or worry about struct utimbuf; gnulib does that for us now.
7661 (gettimeofday): Remove; gnulib provides a substitute.
7662 (make_timeval): New function.
7663 (set_file_times): Now sets ns-resolution time stamps.
7664 New arg FD; all uses changed.
7665 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7666 (system_process_attributes):
7667 Now returns ns-resolution time stamp. All uses changed.
7668 Check for time stamp overflow.
7670 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7671 provides a substitute now.
7673 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7674 since it guarantees struct timespec.
7675 (EMACS_TIME): Now struct timespec, so that we can support
7676 ns-resolution time stamps.
7677 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7678 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7679 (EMACS_USECS): Remove.
7680 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7681 so multiply the arg by 1000 before storing it.
7682 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
7684 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
7685 Port to ns-resolution time stamps.
7686 (EMACS_TIME_NEG_P): Remove; replaced by....
7687 (EMACS_TIME_SIGN): New macro.
7688 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
7689 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
7690 (set_file_times, make_time, lisp_time_argument): Adjust signature.
7691 (make_timeval, make_lisp_time, decode_time_components): New decls.
7692 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7693 that it mishandled time_t overflow. You can't compare by subtracting!
7694 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7695 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
7697 * term.c: Include <sys/time.h>.
7698 (timeval_to_Time): New function, for proper overflow wraparound.
7699 (term_mouse_position, term_mouse_click): Use it.
7701 * undo.c (record_first_change): Support higher-resolution time stamps
7703 (Fprimitive_undo): Use them when restoring time stamps.
7705 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
7706 (w32_get_internal_run_time):
7707 Port to higher-resolution Emacs time stamps.
7708 (ltime): Now accepts single 64-bit integer, as that's more convenient
7711 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
7713 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
7714 for compatibility with pselect. Support ns-resolution time stamps.
7716 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
7718 * xselect.c (wait_for_property_change, x_get_foreign_selection):
7719 Check for time stamp overflow, and support ns-resolution time stamps.
7721 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
7722 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
7723 (timeval_subtract): Remove; no longer needed.
7724 (XTflash, XTring_bell, x_wait_for_event):
7725 Port to ns-resolution time stamps. Don't assume time_t is signed.
7727 2012-06-22 Chong Yidong <cyd@gnu.org>
7729 * xdisp.c (x_consider_frame_title): Revert last change.
7731 2012-06-22 Eli Zaretskii <eliz@gnu.org>
7733 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
7734 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER

8009 as the union type is for debugging, not for production.
8010 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
8011 Use an inline function on all platforms when using the union type,
8012 since this is simpler and 'static inline' can be used portably

8157 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8158 would mishandle a string argument "Xc" if X was a multibyte

8160 rather than including all of X.

8213 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
8214 Convert pctcpu and pctmem to Lisp float properly.
8215 Let the compiler fold better, as 100.0/0x8000 is exact.
8217 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
8219 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
8222 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
8224 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
8226 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
8228 For a 'struct window', replace some Lisp_Object fields to
8229 bitfields where appropriate, remove unused fields.
8230 * window.h (struct window): Remove unused 'last_mark_x' and
8231 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
8232 change its type from Lisp_Object to bitfield.
8233 Change type of 'force_start', 'optional_new_start',
8234 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8235 fields from Lisp_Object to bitfield. Adjust users accordingly.
8237 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8239 Pacify gcc -Wdouble-precision when using Xaw.
8240 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
8241 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
8242 Use 'float' consistently, rather than 'float' in most places
8243 and 'double' in a couple of places.
8245 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8247 * xdisp.c (handle_stop): Detect whether we have overlay strings
8248 loaded by testing it->current.overlay_string_index to be
8249 non-negative, instead of checking whether n_overlay_strings is
8250 positive. (Bug#11587)
8252 2012-05-31 Chong Yidong <cyd@gnu.org>
8254 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
8256 * doc.c (Fsubstitute_command_keys): Doc fix.
8258 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8260 * search.c (search_buffer): Remove calls to
8261 r_alloc_inhibit_buffer_relocation, as it is now called by
8262 maybe_unify_char, which was the cause of relocation of buffer text
8265 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8267 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8268 for the duration of call to load_charset, to avoid problems with
8269 callers of maybe_unify_char that access buffer text through C
8272 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8273 decrement the inhibition flag, instead of just setting or
8276 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8278 Remove obsolete '#define static' cruft.
8279 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8280 This #undef was "temporary" in 2000; it is no longer needed
8281 now that '#define static' has gone away.
8282 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8283 (gray_bitmap_bits): Remove; no longer needed.
8284 All uses replaced with definiens.
8285 * xterm.c: Include "bitmaps/gray.xbm".
8287 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8289 Clean up __executable_start, monstartup when --enable-profiling.
8290 The following changes affect the code only when profiling.
8291 * dispnew.c (__executable_start): Rename from safe_bcopy.
8292 Define only on platforms that need it.
8293 * emacs.c: Include <sys/gmon.h> when profiling.
8294 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
8295 (__executable_start): Remove decl, since lisp.h does it now.
8296 (safe_bcopy): Remove decl; no longer has that name.
8297 (main): Coalesce #if into single bit of code, for simplicity.
8298 Cast pointers to uintptr_t, since standard libraries want integers
8300 * lisp.h (__executable_start): New decl.
8302 2012-05-31 Glenn Morris <rgm@gnu.org>
8304 * image.c (Fimagemagick_types): Doc fix.
8306 2012-05-30 Jim Meyering <meyering@redhat.com>
8308 * callproc.c (Fcall_process_region): Include directory component
8309 in mkstemp error message (Bug#11586).
8311 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8313 * alloc.c, lisp.h (make_pure_vector): Now static.
8315 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

8322 * lisp.h (Qdefun): Remove.
8323 * lread.c (read1): Tiny simplification.
8325 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
8327 Do not create empty overlays with the evaporate property (Bug#9642).
8328 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8329 Bug#9642, but explicitly check that the buffer the overlay would
8330 be moved to is live and rearrange lines to make sure that errors
8331 will not put the overlay in an inconsistent state.
8332 (Fdelete_overlay): Cosmetics.
8334 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8336 * w32term.c (my_bring_window_to_top): New function.
8337 (x_raise_frame): Use handle returned by DeferWindowPos, which
8338 could be different from the original one.
8339 Call my_bring_window_to_top instead of my_set_foreground_window.
8342 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
8343 by calling BringWindowToTop.
8345 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
8346 (WM_EMACS_END): Increase by one.
8348 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
8350 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
8351 This avoids undefined behavior that might cause the eassert
8352 to not catch an out-of-range value.
8354 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8356 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
8357 Update dependencies.
8359 2012-05-27 Eli Zaretskii <eliz@gnu.org>
8361 * bidi.c (bidi_mirror_char): Fix last change.
8363 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
8365 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
8366 when referring to sectname field in printf format.
8368 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
8370 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8371 Only r_alloc_inhibit_buffer_relocation needed to be added;
8372 the others were already declared.
8374 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8375 before checking whether it's out of range. Put the check inside
8377 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8379 2012-05-27 Ken Brown <kbrown@cornell.edu>
8381 * callproc.c (Fcall_process): Restore a line that was accidentally
8382 commented out in the 2011-02-13 change (bug#11547).
8384 2012-05-27 Eli Zaretskii <eliz@gnu.org>
8386 * lisp.h [REL_ALLOC]: Add prototypes for external functions
8387 defined on ralloc.c.
8389 * buffer.c [REL_ALLOC]: Remove prototypes of
8390 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
8391 they are now on lisp.h.
8393 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8395 * search.c (search_buffer): Use it to inhibit relocation of buffer
8396 text while re_search_2 is doing its job, because re_search_2 is
8397 passed C pointers to buffer text. (Bug#11519)
8399 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8402 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8403 state after an additional call to move_it_in_display_line_to, keep
8404 the values of it->max_ascent and it->max_descent found for the
8406 (pos_visible_p): Revert the comparison against bottom_y to what it
8407 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8410 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8412 Fix coding-related core dumps with gcc -ftrapv.
8413 The code was computing A - B, where A and B are pointers, and B is
8414 random garbage. This can lead to core dumps on platforms that
8415 have special pointer registers, and it also leads to core dumps on
8416 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8417 A - B only when B is initialized properly.
8418 * coding.c (coding_set_source, coding_set_destination): Return void.
8419 (coding_change_source, coding_change_destinations): New functions,
8420 with the old behaviors of coding_set_source and coding_set_destination.
8421 All callers that need an offset changed to use these new functions.
8423 2012-05-26 Glenn Morris <rgm@gnu.org>
8425 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
8427 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8429 Extend mouse support on W32 text-mode console.
8430 * xdisp.c (draw_row_with_mouse_face):
8431 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8433 * w32console.c: Include window.h.
8434 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8436 (initialize_w32_display): Initialize mouse-highlight data.
8438 * w32inevt.c: Include termchar.h and window.h.
8439 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8440 moves, call note_mouse_highlight. If help_echo changed, call
8441 gen_help_event to produce help-echo message in the echo area.
8442 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8445 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8447 * lread.c (read1): Simplify slightly to avoid an overflow warning
8448 with GCC 4.7.0 on x86-64.
8450 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8452 * bidi.c (bidi_mirror_char): Revert last change: an int is
8453 definitely wide enough here.
8455 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
8457 Fix integer width and related bugs (Bug#9874).
8458 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
8459 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
8460 (string_bytes, check_sblock, allocate_string_data):
8461 (compact_small_strings, Fmake_bool_vector, make_string)

8463 (make_string_from_bytes, make_specified_string)
8464 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
8465 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
8467 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8468 (allocate_pseudovector):
8469 Use int, not EMACS_INT, where int is wide enough.
8470 (inhibit_garbage_collection, Fgarbage_collect):
8471 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8472 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
8473 int might not be wide enough.
8474 (bidi_cache_search, bidi_cache_find, bidi_init_it)
8475 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
8476 (bidi_at_paragraph_end, bidi_find_paragraph_start)
8477 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
8478 (bidi_level_of_next_char, bidi_move_to_visually_next):
8479 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8480 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
8481 (Fkill_buffer, Fset_buffer_major_mode)
8482 (advance_to_char_boundary, Fbuffer_swap_text)
8483 (Fset_buffer_multibyte, overlays_at, overlays_in)
8484 (overlay_touches_p, struct sortvec, record_overlay_string)
8485 (overlay_strings, recenter_overlay_lists)
8486 (adjust_overlays_for_insert, adjust_overlays_for_delete)
8487 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
8488 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
8489 (Foverlay_recenter, last_overlay_modification_hooks_used)
8490 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8491 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8492 (validate_region): Omit unnecessary test for b <= e,
8493 since that's guaranteed by the previous test.
8494 (adjust_overlays_for_delete): Avoid pos + length overflow.
8495 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8496 (report_overlay_modification):
8497 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8498 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
8499 Omit pointer cast, which isn't needed anyway, and doesn't work
8500 after the EMACS_INT -> ptrdiff_t change.
8501 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
8502 * buffer.h: Adjust decls to match defn changes elsewhere.
8503 (struct buffer_text, struct buffer):
8504 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8505 Use EMACS_INT, not int, where int might not be wide enough.
8506 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
8507 not int, to avoid needless 32-bit limit on 64-bit hosts.
8508 (exec_byte_code): Use tighter memory-full test, one that checks
8509 for alloca overflow. Don't compute the address of the object just
8510 before an array, as that's not portable. Use EMACS_INT, not
8511 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8512 * callint.c (Fcall_interactively):
8513 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8514 * callproc.c (call_process_kill, Fcall_process):
8515 Don't assume pid_t fits into an Emacs fixnum.
8516 (call_process_cleanup, Fcall_process, child_setup):
8517 Don't assume pid_t fits into int.
8518 (call_process_cleanup, Fcall_process, delete_temp_file)
8519 (Fcall_process_region):
8520 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8521 (Fcall_process): Simplify handling of volatile integers.
8522 Use int, not EMACS_INT, where int will do.
8523 * casefiddle.c (casify_object, casify_region, operate_on_word)
8524 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
8525 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8526 (casify_object): Avoid integer overflow when overallocating buffer.
8527 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
8528 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
8529 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
8530 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8531 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8532 integers are now checked earlier. All uses replaced with XINT.
8534 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8535 For CCL_MapSingle, check that content and value are in int range.
8536 (ccl_driver, Fregister_code_conversion_map):
8537 Check that Vcode_version_map_vector is a vector.
8538 (resolve_symbol_ccl_program): Check that vector header is in range.
8539 Always copy the vector, so that we can check its contents reliably
8540 now rather than having to recheck each instruction as it's being
8541 executed. Check that vector words fit in 'int'.
8542 (ccl_get_compiled_code, Fregister_ccl_program)
8543 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8544 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
8545 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
8546 contents are in range.
8547 (Fccl_execute_on_string): Check that status is in range.
8548 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8549 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8550 Accept and return EMACS_INT, not int, because callers can pass values
8552 (c_string_width, strwidth, lisp_string_width, chars_in_text)
8553 (multibyte_chars_in_text, parse_str_as_multibyte)
8554 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
8555 (str_as_unibyte, str_to_unibyte, string_count_byte8)
8556 (string_escape_byte8, Fget_byte):
8557 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8558 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
8559 avoid mishandling large integers.
8560 * character.h: Adjust decls to match defn changes elsewhere.
8561 * charset.c (load_charset_map_from_file, find_charsets_in_text)
8562 (Ffind_charset_region):
8563 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8564 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
8565 (load_charset_map_from_vector, Fdefine_charset_internal):
8566 Don't assume fixnum fits in int.
8567 (load_charset_map_from_vector, Fmap_charset_chars):
8568 Remove now-unnecessary CHECK_NATNUMs.
8569 (Fdefine_charset_internal): Check ranges here, more carefully.
8570 Don't rely on undefined behavior with signed left shift overflow.
8571 Don't assume unsigned int fits into fixnum, or that fixnum fits
8572 into unsigned int. Don't require max_code to be a valid fixnum;
8573 that's not true for gb10830 4-byte on a 32-bit host. Allow
8574 invalid_code to be a cons, for the same reason. Require code_offset
8575 to be a character. Avoid int overflow if max_char is close
8577 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8578 this is intended anyway and avoids some undefined behavior.
8579 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8580 INDEX_TO_CODE_POINT, as that's what it expects.
8581 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8582 * charset.h (DECODE_CHAR): Return int, not unsigned;
8583 this is what was intended anyway, and it avoids undefined behavior.
8584 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8585 integer-overflow issues.
8586 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8587 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8588 where the argument is EMACS_INT, and this behavior is not intended.
8589 * chartab.c (Fmake_char_table, Fset_char_table_range)
8590 (uniprop_get_decoder, uniprop_get_encoder):
8591 Don't assume fixnum fits in int.
8592 * cmds.c (move_point): New function, that does the gist of
8593 Fforward_char and Fbackward_char, but does so while checking
8594 for integer overflow more accurately.
8595 (Fforward_char, Fbackward_char): Use it.
8596 (Fforward_line, Fend_of_line, internal_self_insert)
8597 (internal_self_insert):
8598 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8599 Fix a FIXME, by checking for integer overflow when calculating
8600 target_clm and actual_clm.

9348 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
9350 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
9351 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
9353 2012-05-18 Eli Zaretskii <eliz@gnu.org>
9355 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
9357 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
9358 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
9360 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
9361 reference to image_cache->refcount.
9362 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
9364 2012-05-17 Juri Linkov <juri@jurta.org>
9366 * search.c (Fword_search_regexp, Fword_search_backward)
9367 (Fword_search_forward, Fword_search_backward_lax)
9368 (Fword_search_forward_lax): Move functions to isearch.el
9369 (bug#10145, bug#11381).
9371 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
9373 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
9375 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
9377 * lread.c (init_obarray): Declare Qt and Qnil as special.
9379 2012-05-14 Glenn Morris <rgm@gnu.org>
9381 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9382 Put "libexec" before "bin", for the sake of init_callproc_1.
9384 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9386 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
9388 * unexaix.c: Port to more-recent AIX compilers.
9389 (report_error, report_error_1, make_hdr, copy_sym)
9390 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9391 Make arguments const char *, not char *, to avoid violations of C
9392 standard and to fix some AIX warnings reported by Gilles Pion.
9394 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9396 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9397 already have overlays loaded.
9398 (handle_single_display_spec): Before returning without displaying
9399 fringe bitmap, synchronize the bidi iterator with the main display
9400 iterator, by calling iterate_out_of_display_property.
9401 (iterate_out_of_display_property): Detect buffer iteration by
9402 testing that it->string is a Lisp string.
9403 (get_next_display_element): When the current object is exhausted,
9404 and there's something on it->stack, call set_iterator_to_next to
9405 proceed with what's on the stack, instead of returning zero.
9406 (set_iterator_to_next): If called at the end of a Lisp string,
9407 proceed to consider_string_end without incrementing string
9408 position. Don't increment display vector index past the end of
9409 the display vector. (Bug#11417)
9410 (pos_visible_p): Don't report a position visible when move_it_to
9411 stopped at the last line of window, which happens to be scanned
9412 backwards by the bidi iteration. (Bug#11464)
9414 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9416 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9417 and right-margin display specs even if the spec is invalid or we
9418 are on a TTY, and thus unable to display on the fringes.
9419 That's because the text with the property will not be displayed anyway,
9420 so we need to signal to the caller that this is a "replacing"
9421 display spec. This fixes display when the spec is invalid or we
9424 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9426 * unexaix.c (make_hdr): Fix typo in prototype.
9427 This bug broke the build on AIX. Problem reported by Gilles Pion.
9429 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9431 * keyboard.c (kbd_buffer_get_event): Read special events also in
9432 batch mode. (Bug#11415)
9434 2012-05-12 Glenn Morris <rgm@gnu.org>
9436 * ns.mk: Update for ns_appbindir no longer having trailing "/".
9438 2012-05-12 Eli Zaretskii <eliz@gnu.org>
9440 * lisp.mk (lisp): Add newcomment.elc.
9442 2012-05-12 Glenn Morris <rgm@gnu.org>
9444 * Makefile.in (MKDIR_P): New, set by configure.
9445 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9447 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9449 Remove unused function hourglass_started.
9450 * dispextern.h (hourglass_started):
9451 * w32fns.c (hourglass_started):
9452 * xdisp.c (hourglass_started): Remove.
9454 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
9456 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
9457 Update dependencies.
9459 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9461 * xgselect.c (xg_select): Put maxfds+1 into a var.
9462 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9464 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9466 2012-05-10 Dave Abrahams <dave@boostpro.com>
9468 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9469 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9471 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9473 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9474 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9475 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9476 Initialize xd_registered_buses.
9478 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9480 Untag more efficiently if USE_LSB_TAG.
9481 This is based on a proposal by YAMAMOTO Mitsuharu in
9482 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9483 For an admittedly artificial (nth 8000 longlist) benchmark on
9484 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9485 Emacs's overall text size by 1%.
9486 * lisp.h (XUNTAG): New macro.
9487 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9488 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9489 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9490 * eval.c (Fautoload):
9491 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9492 * frame.h (XFRAME): Use XUNTAG.
9494 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9495 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9496 Remove unportable assumptions about print widths of types like
9498 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9499 intptr_t when converting between pointer and integer, to avoid GCC
9500 warnings about wrong width.
9502 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9504 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9505 stack for each reader_thread, instead of defaulting to 8MB
9506 determined by the linker. This avoids failures in creating
9507 subprocesses on Windows 7, see the discussion in this thread:
9508 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9510 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9512 Fix up display of the *Minibuf-0* buffer in the mini window.
9513 * keyboard.c (read_char): Don't clear the echo area if there's no
9515 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9516 contents of *Minibuf-0*) if there's no message displayed in its stead.
9518 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9520 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9523 2012-05-06 Chong Yidong <cyd@gnu.org>
9525 * lisp.mk (lisp): Update.
9527 2012-05-05 Jim Meyering <meyering@redhat.com>
9529 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9531 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9533 * data.c (PUT_ERROR): New macro.
9534 (syms_of_data): Use it. Add new error type `user-error'.
9535 * undo.c (user_error): New function.
9536 (Fprimitive_undo): Use it.
9537 * print.c (print_error_message): Adjust print style for `user-error'.
9538 * keyboard.c (user_error): New function.
9539 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9541 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9543 Do not limit current-time-string to years 1000..9999.
9544 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9545 (Fcurrent_time_string): Support any year that is supported by the
9546 underlying localtime representation. Don't use asctime, as it
9547 has undefined behavior for years outside the range -999..9999.
9549 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9551 Fix race conditions involving setenv, gmtime, localtime, asctime.
9552 Without this fix, interrupts could mess up code that uses these
9553 nonreentrant functions, since setting TZ invalidates existing
9554 tm_zone or tzname values, and since most of these functions return
9555 pointers to static storage.
9556 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9557 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9558 Grow the critical sections to include not just invoking
9559 localtime/gmtime, but also accessing these functions' results
9560 including their tm_zone values if any, and any related TZ setting.
9561 (format_time_string): Last arg is now struct tm *, not struct tm **,
9562 so that the struct tm is saved in the critical section.
9563 All callers changed. Simplify allocation of initial buffer, partly
9564 motivated by the fact that memory allocation needs to be outside
9565 the critical section.
9567 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9569 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9570 with RESET_INTERVAL.
9572 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9573 Remove duplicated buffer name initialization.
9575 2012-05-02 Jim Meyering <jim@meyering.net>
9577 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9579 * xfns.c (x_window): Use xstrdup (Bug#11375).
9581 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9583 * xdisp.c (pos_visible_p): If already at a newline from the
9584 display string before the 'while' loop, don't walk back the glyphs
9585 from it3.glyph_row. Solves assertion violation when the display
9586 string begins with a newline (egg.el). (Bug#11367)
9588 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9590 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9593 2012-05-01 Glenn Morris <rgm@gnu.org>
9595 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9596 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9597 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9598 All were removed before 23.1.
9600 * dispnew.c: Remove HAVE_LIBNCURSES test;
9601 it is always true on relevant platforms.
9603 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9604 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9606 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9608 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9610 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9611 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9614 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9616 Do not avoid creating empty evaporating overlays (Bug#9642).
9617 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9618 That is, do not delete an evaporating overlay if it becomes
9619 empty after its bounds are adjusted to fit within its buffer.
9620 This fix caused other problems, and I'm reverting it until we get
9621 to the bottom of them.
9623 2012-04-27 Chong Yidong <cyd@gnu.org>
9625 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9627 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9629 * xdisp.c (pos_visible_p): If the window start position is beyond
9630 ZV, start the display from buffer beginning. Prevents assertion
9631 violation in init_iterator when the minibuffer window is scrolled
9634 * window.c (window_scroll_pixel_based): Likewise.
9636 2012-04-27 Chong Yidong <cyd@gnu.org>
9638 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9640 2012-04-27 Glenn Morris <rgm@gnu.org>
9642 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9643 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9645 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9647 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9648 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9650 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9652 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9653 display element, check also the underlying string or buffer
9654 character. (Bug#11341)
9656 * w32menu.c: Include w32heap.h.
9657 (add_menu_item): If the call to AppendMenuW (via
9658 unicode_append_menu) fails, disable Unicode menus only if we are
9659 running on Windows 9X/Me.
9661 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9663 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9664 (xgetint): Add missing shift for LSB tags.
9666 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9668 * keyboard.c (read_char): Don't wipe echo area for select window
9669 events: These might get delayed via `mouse-autoselect-window'
9672 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9674 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9675 manipulation of :loaded-from data.
9677 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9679 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9680 now a cons (bug#11311).
9682 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9684 Do not create empty overlays with the evaporate property (Bug#9642).
9685 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9686 if it becomes empty after its bounds are adjusted to fit within
9687 its buffer. Without this fix, in a nonempty buffer (let ((o
9688 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9689 yields an empty overlay that has the evaporate property, which is
9690 not supposed to happen.
9692 Fix minor GTK3 problems found by static checking.
9693 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9694 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9695 (struct _EmacsFixedClass, emacs_fixed_get_type):
9696 Move decls here from emacsgtkfixed.h, since they needn't be public.
9697 (emacs_fixed_get_type): Now static.
9698 (emacs_fixed_class_init): Omit unused local.
9699 (emacs_fixed_child_type): Remove; unused.

9701 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9702 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
9703 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
9704 (EMACS_FIXED_GET_CLASS): Remove; unused.
9705 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9707 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9708 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9710 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9712 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9713 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9714 (__malloc_size_t, __malloc_ptrdiff_t):
9715 Remove. All uses removed, replaced by the definiens if needed,
9716 since we can assume C89 or better now.
9717 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
9718 (protect_malloc_state, align, get_contiguous_space)
9719 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

9725 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
9726 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9727 Define using prototypes, not old style.
9728 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9729 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
9730 (align): Don't assume that signed integer overflow wraps around.
9731 Omit unused local var.
9732 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
9733 (_free_internal_nolock, memalign, mallochook, reallochook):
9734 Omit no-longer-needed casts.
9735 (valloc): Use getpagesize, not __getpagesize.
9736 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
9737 (struct hdr): The 'magic' member is now size_t, not unsigned long.
9739 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
9741 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
9743 Move functions from C to Lisp. Make non-blocking method calls
9744 the default. Implement further D-Bus standard interfaces.
9746 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
9747 (QCdbus_request_name_allow_replacement)
9748 (QCdbus_request_name_replace_existing)

9786 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9788 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
9789 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
9790 Do not assume ptrdiff_t is the same width as 'int'.
9792 * alloc.c: Handle unusual debugging option combinations.
9793 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
9794 since the two debugging options are incompatible.
9795 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
9797 (mem_init, mem_insert, mem_insert_fixup):
9798 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
9799 (NEED_MEM_INSERT): Remove; no longer needed.

9807 * sysdep.c [__FreeBSD__]: Minor cleanups.
9808 (list_system_processes, system_process_attributes) [__FreeBSD__]:
9809 Use Emacs indenting style more consistently. Avoid some casts.

9824 It is never used otherwise.
9826 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
9828 * print.c (print_preprocess): Only check print_depth if print-circle
9830 (print_object): Check for cycles even when print-circle is nil and
9831 print-gensym is t, but only check print_depth if print-circle is nil.
9833 2012-04-20 Chong Yidong <cyd@gnu.org>
9835 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9836 set the status to "failed" and ensure that sentinel is run.
9838 2012-04-20 Glenn Morris <rgm@gnu.org>

9849 row, return zero immediately.
9850 (try_cursor_movement): If inside continuation line, don't back up
9851 farther than the first row after the header line, if any.
9852 Don't consider the header-line row as "partially visible", even if
9853 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
9855 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

9869 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
9870 -Wunused-result, -Wunused-variable. This should go away once
9871 the Emacs and Gnulib regex code is merged.
9872 (xmalloc, xrealloc): Now static.
9874 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

9890 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
9891 New extern decls, to avoid calling undeclared functions.
9892 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9893 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9894 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
9895 (NEED_MEM_INSERT): New macro.
9896 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9897 Remove one incorrect comment and fix another.

9903 (r_alloc_sbrk): Now static.
9905 Improve ralloc.c interface checking.
9906 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

9911 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
9912 Remove decls. This fixes an "It stinks!".
9914 * alloc.c (which_symbols): Fix alignment issue / type clash.
9916 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9918 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
9919 (struct Lisp_Misc_Any): Likewise.

9929 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
9931 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
9932 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
9933 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
9934 * s/netbsd.h, s/sol2-6.h:
9935 Remove definition of GC_MARK_STACK, since the default now works.
9936 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
9937 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
9938 no longer the default.
9939 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
9941 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
9943 * lread.c (lisp_file_lexically_bound_p):
9944 Fix hang at ";-*-\n" (bug#11238).
9946 2012-04-14 Eli Zaretskii <eliz@gnu.org>

9958 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
9960 2012-04-13 Reuben Thomas <rrt@sc3d.org>
9962 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
9964 2012-04-11 Daniel Colascione <dancol@dancol.org>
9966 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
9967 against is gone. It's better to use vfork now so that when Cygwin
9968 gains a new, working vfork, we use it automatically (bug#10398).
9970 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
9972 * window.c (save_window_save): Obey window-point-insertion-type.

9988 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
9990 * w32.c (w32_delayed_load): Record the full path of the library
9991 being loaded (bug#10424).
9993 2012-04-09 Glenn Morris <rgm@gnu.org>
9995 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
9996 not just in the obarray, before snarfing them. (Bug#11036)
9998 * Makefile.in ($(leimdir)/leim-list.el):

10008 Add convenience `GNUTLS_LOG2i' macro.
10010 * gnutls.c (gnutls_log_function2i): Convenience log function.
10011 (emacs_gnutls_read): Use new log functions,
10012 `gnutls_handshakes_tried' process member, and
10013 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10014 attempts per process (connection).
10016 2012-04-09 Chong Yidong <cyd@gnu.org>
10018 * eval.c (Fuser_variable_p, user_variable_p_eh)

10023 * minibuf.c (Fread_variable): Callers changed.
10025 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10027 * xdisp.c (set_cursor_from_row): If the display string appears in
10028 the buffer at position that is closer to point than the position
10029 after the display string, display the cursor on the first glyph of
10030 the display string. Fixes cursor display when a 'display' text
10031 property immediately follows invisible text. (Bug#11094)
10033 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10035 composite.c: use 'double' consistently
10036 * composite.c (get_composition_id): Use 'double' consistently
10037 instead of converting 'float' to 'double' and vice versa; this is
10038 easier to understand and avoids a GCC warning.
10040 2012-04-09 Glenn Morris <rgm@gnu.org>
10042 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10043 preparation for dumping it with emacs. (Bug#4789)

10064 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
10065 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10066 (mark_memory): Mark Lisp_Objects only if pointers might hide in
10067 objects, as mark_maybe_pointer will catch them otherwise.

10080 * makefile.w32-in (OBJ2): Add xml.$(O).
10081 (GLOBAL_SOURCES): Add xml.c.
10082 ($(BLD)/xml.$(O)): New dependency list.
10084 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
10085 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
10086 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
10087 [!WINDOWSNT]: New macros.
10088 (init_libxml2_functions, libxml2_loaded_p): New functions.
10089 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10090 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10091 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10092 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10094 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10095 Call init_libxml2_functions before calling libxml2 functions.
10096 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10098 * emacs.c: Don't include libxml/parser.h.
10099 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
10100 xmlCleanupParser directly.
10102 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
10104 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10106 * indent.c (Fvertical_motion): If there is a display string at
10107 point, use it.vpos to compute how many lines to backtrack after
10108 move_it_to point. (Bug#11133)
10110 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10112 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10113 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10114 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10115 macros related to unification of CJK characters. For the details,
10116 see the discussion following the message here:
10117 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10119 2012-04-04 Chong Yidong <cyd@gnu.org>
10121 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10123 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10125 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
10126 instead of alloca. (Bug#11138)
10128 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
10130 * w32menu.c (is_simple_dialog): Properly check lisp types.
10133 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10135 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10136 position we get to after a call to move_it_to fails the
10137 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10138 only if we wind up in a string from display property. (Bug#11063)
10140 * window.c (Fdelete_other_windows_internal): Invalidate the row
10141 and column information about mouse highlight, so that redisplay
10142 restores it after reallocating the glyph matrices. (Bug#7464)
10144 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10145 string comes from a `display' text property, use the buffer
10146 position of that property as if we actually saw that position in
10148 (move_it_by_lines): Remove the assertion that
10149 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10150 violated when there's a before-string at the beginning of a line.
10153 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10155 * xdisp.c (append_space_for_newline): If the default face was
10156 remapped, use the remapped face for the appended newline.

10158 extending the face to the end of the line.
10159 (display_line): Call extend_face_to_end_of_line when the default
10160 face was remapped. (Bug#11068)
10162 2012-03-29 Eli Zaretskii <eliz@gnu.org>
10164 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

10182 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10183 (command_loop_1): Use it; inhibit selection update for
10184 handle-select-window too (Bug#8996).

10188 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
10190 2012-03-25 Kenichi Handa <handa@m17n.org>
10192 * dispextern.h (struct glyph): Change the bit length of
10193 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10195 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10197 * s/ms-w32.h (tzname): Include time.h before redirecting to

10202 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10205 * xterm.c (XTread_socket): Only modify handling_signal if
10206 !SYNC_INPUT. (Bug#11080)
10208 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10210 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10211 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10212 when fetching a multibyte character consumes more bytes than
10213 CHAR_BYTES returns, due to unification of CJK characters in
10214 string_char. (Bug#11073)
10216 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10218 * process.c (wait_reading_process_output): Handle pty disconnect
10219 by refraining from sending oneself a SIGCHLD (bug#10933).
10221 2012-03-22 Chong Yidong <cyd@gnu.org>
10223 * dispextern.h (struct it): New member string_from_prefix_prop_p.
10225 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
10226 Mark string as coming from a prefix property.
10227 (handle_face_prop): Use default face for prefix strings (Bug#4281).
10228 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
10230 2012-03-21 Chong Yidong <cyd@gnu.org>
10232 * xfaces.c (Vface_remapping_alist): Doc fix.
10234 2012-03-20 Eli Zaretskii <eliz@gnu.org>
10236 * w32proc.c (Fw32_set_console_codepage)

10248 it fit in a valid range (Bug#11003).
10250 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10252 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10253 that is not from display property, accept the row as a "cursor
10254 row" if one of the string's character has a non-nil `cursor'
10255 property. Fixes cursor positioning when there are newlines in
10256 overlay strings, e.g. in icomplete.el. (Bug#11035)
10258 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10260 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10262 2012-03-12 Chong Yidong <cyd@gnu.org>
10264 * eval.c (inhibit_lisp_code): Rename from

10292 2012-03-03 Glenn Morris <rgm@gnu.org>
10294 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10296 2012-03-02 Eli Zaretskii <eliz@gnu.org>

10300 (redisplay_window, next_element_from_string): Fix typos in
10302 (redisplay_window): Pass to move_it_vertically the margin in

10309 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10311 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10312 push_it before setting up the iterator for the first overlay
10313 string, even if we have an empty string loaded.
10314 (next_overlay_string): If there's an empty string on the iterator
10315 stack, pop the stack. (Bug#10903)
10317 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10319 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10320 Suggested by Stefan Monnier in
10321 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10322 * alloc.c (widen_to_Lisp_Object): New static function.
10323 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10324 and widening them to Lisp_Objects. This would work even if
10325 USE_LSB_TAG is defined and wide integers are used, which might
10326 happen in a future version of Emacs.
10328 2012-02-25 Chong Yidong <cyd@gnu.org>
10330 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

10335 before saving to clipboard manager.
10337 2012-02-24 Chong Yidong <cyd@gnu.org>
10339 * keyboard.c (process_special_events): Handle all X selection
10340 requests in kbd_buffer, not just the next one (Bug#8869).
10342 2012-02-23 Chong Yidong <cyd@gnu.org>
10344 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10345 call when setting menu-bar-lines and tool-bar-lines parameters.
10346 (unwind_create_frame_1): New helper function.
10348 * window.c (inhibit_window_configuration_change_hook): New var.
10349 (run_window_configuration_change_hook): Obey it.

10367 when computing $valmask.
10369 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10370 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10371 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10372 It's useless in that case, and it can cause problems on hosts
10373 that allocate halves of EMACS_INT values separately.
10374 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10375 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10376 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10377 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10378 it avoids undefined behavior on hosts where shifting right by more
10379 than the word width has undefined behavior.
10381 2012-02-19 Chong Yidong <cyd@gnu.org>
10383 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10384 (Funhandled_file_name_directory, Ffile_name_as_directory)
10385 (Fdirectory_file_name, Fexpand_file_name)
10386 (Fsubstitute_in_file_name): Protect against invalid file handler
10387 return values (Bug#10845).

10403 2012-02-15 Chong Yidong <cyd@gnu.org>
10405 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is

10421 2012-02-12 Chong Yidong <cyd@gnu.org>
10423 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10424 as that creates a dangerous corner case.
10426 * window.c (Fdelete_window_internal): Invalidate the mouse
10427 highlight (Bug#9904).
10429 2012-02-12 Glenn Morris <rgm@gnu.org>

10436 (Fx_selection_owner_p, Fx_get_selection_internal):
10437 Sync docs and argument specs with the xselect.c versions.
10439 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

10459 2012-02-07 Chong Yidong <cyd@gnu.org>
10461 * buffer.c (Fbuffer_local_variables)
10462 (buffer_lisp_local_variables): Handle unbound vars correctly;
10463 don't let Qunbound leak into Lisp.
10465 2012-02-07 Glenn Morris <rgm@gnu.org>
10467 * image.c (Fimagemagick_types): Doc fix.
10469 * image.c (imagemagick-render-type): Change it from a lisp object
10470 to an integer. Move the doc here from the lisp manual.

10500 before BEGV. (Bug#10696)
10502 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
10504 Handle overflow when computing char display width (Bug#9496).
10505 * character.c (char_width): Return EMACS_INT, not int.
10506 (char_width, c_string_width): Check for overflow when
10507 computing the width; this is possible now that individual
10508 characters can have unbounded width. Problem introduced
10509 by merge from Emacs 23 on 2012-01-19.

10540 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
10541 first 2 arguments are identical. This makes inserting large
10542 output from a subprocess an order of magnitude faster on
10543 MS-Windows, where all sbrk'ed memory is always contiguous.

10643 DISP_STRING, and accept any glyph in a row whose object is that
10644 string as eligible for mouse highlight. Fixes mouse highlight of
10645 display strings from overlays. (Bug#10464)
10647 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
10649 emacs: fix an auto-save permissions race condition (Bug#10400)

11162 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
11163 is set, removing the need for VIRT_ADDRESS_VARIES.
11164 (PURE_P): Use a more-efficient implementation that needs just one

11179 (erase_phys_cursor, update_window_cursor, show_mouse_face)
11180 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
11181 behave as if the cursor position were at the window margin.
11183 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11184 and the cursor position is out of bounds, behave as if the cursor
11185 position were at the window margin. (Bug#10075)
11187 2011-11-18 Chong Yidong <cyd@gnu.org>
11189 * window.c (Fwindow_combination_limit): Make first argument

11210 * xdisp.c (row_hash): New function, body extracted from
11211 compute_line_metrics.
11212 (compute_line_metrics): Call row_hash, instead of computing the
11215 * dispnew.c (verify_row_hash): Call row_hash for computing the
11216 hash code of a row, instead of duplicating code from xdisp.c.
11218 * dispextern.h (row_hash): Add prototype.
11220 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
11222 * frame.c (delete_frame): Don't delete the terminal when the last

11406 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11407 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11408 * intervals.c (adjust_intervals_for_insertion)

11411 (static_offset_intervals): Remove.
11412 (offset_intervals): Rewrite using the old contents of
11413 static_offset_intervals. The old version didn't conform to C99
11414 because an extern inline function contained a reference to an
11415 identifier with static linkage.

11678 * gnutls.c (emacs_gnutls_deinit): New function.
11679 Deallocate credentials structures as well as calling gnutls_deinit.
11680 (Fgnutls_deinit, Fgnutls_boot): Use it.
11682 * process.c (make_process): Initialize GnuTLS credentials to NULL.
11683 (deactivate_process): Call emacs_gnutls_deinit.
11685 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11687 * image.c (x_create_x_image_and_pixmap):
11688 * w32.c (sys_rename, w32_delayed_load):
11689 * w32font.c (fill_in_logfont):
11690 * w32reg.c (x_get_string_resource): Silence compiler warnings.
11692 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
11694 * w32fns.c (w32_default_color_map): New function,
11695 extracted from Fw32_default_color_map.
11696 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
11698 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
11700 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
11702 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
11704 * keyboard.c (test_undefined): New function (bug#9751).
11705 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
11707 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
11709 * sysdep.c (init_sys_modes): Fix the check for the controlling
11710 terminal (Bug#6649).
11712 2011-10-20 Eli Zaretskii <eliz@gnu.org>
11714 * dispextern.h (struct bidi_it): New member next_en_type.
11716 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11717 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11718 current character, check also for next_en_type being WEAK_EN.
11719 (bidi_resolve_weak): Don't enter the expensive loop if the current
11720 position is before next_en_pos. Record the bidi type of the first
11721 non-ET, non-BN character we find, in addition to its position.
11722 (bidi_level_of_next_char): Invalidate next_en_type when
11723 next_en_pos is over-stepped.
11725 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11727 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11728 * editfns.c: Rewrite current-time-zone so that it invokes
11729 the equivalent of (format-time-string "%Z") to get the time zone name.
11730 This fixes a bug when the time zone name contains characters that
11731 need converting from the system time locale to Emacs internal format.
11732 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11733 that patch fixed format-time-string to do the conversion, but
11734 I forgot to fix current-time-zone.
11735 (format_time_string): New function, containing most of
11736 what Fformat_time_string used to contain.
11737 (Fformat_time_string): Rewrite in terms of format_time_string.
11738 This doesn't change this function's behavior.
11739 (current-time-zone): Rewrite to use format_time_string.
11740 This fixes the bug reported by Michael Schierl in
11741 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11742 Jason Rumney's 2007-06-07 change worked around this bug, but
11744 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11746 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11748 * xdisp.c (start_display): If the character at POS is displayed
11749 via a display vector, reset IT->current.dpvec_index to zero.
11750 (try_window_reusing_current_matrix): If a line ends in a display
11751 vector or the next line starts in a display vector, continue
11752 redrawing the window even though the character position of
11753 start_row was reached.
11756 2011-10-18 Chong Yidong <cyd@gnu.org>
11758 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11759 with nobreak-char-display too.
11761 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11763 Fix part 3 of bug#9771.
11764 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11765 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11766 non-neutral characters if the current character is a paragraph
11767 separator (a.k.a. Newline). This avoids running the same
11768 expensive loop twice, once when we consume the preceding newline
11769 and the other time when the line actually needs to be displayed.
11770 Avoid the loop when we see neutrals on the base embedding level
11771 following a character whose directionality is the same as the
11772 paragraph's. This avoids running the expensive loop when a line
11773 ends in a long sequence of neutrals, like control characters.
11774 Add assertion against STRONG_AL type. Slightly rearrange code
11775 that determines the type of a neutral given the first non-neutral
11777 (bidi_level_of_next_char): Set next_en_pos to zero when
11778 invalidating its info.
11780 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11782 * xdisp.c (push_display_prop): Determine whether to record string
11783 or buffer position by IT->string, not by IT->method. Allow
11784 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11785 (move_it_vertically_backward): Don't look for character position
11786 immediately after the newline when in a continuation line.
11789 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11791 * window.c (coordinates_in_window): Rewrite and delabelize
11792 vertical border check. (Bug#5357) (Bug#9618)
11794 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11796 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11797 errors in XSetWindowBorder (bug#9310).
11799 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11801 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11802 avoid crash when xmalloc overrun checking is enabled.
11804 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11806 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11807 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11808 cursor motion with <left> and <right> arrow keys.
11810 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11811 some callers set that themselves.
11813 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11815 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11816 display string and the previous row comes from the same string and
11817 is empty. (Bug#9739) (Bug#9738)
11819 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11821 * doc.c (get_doc_string): Encode file name (bug#9735).
11823 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11825 * bidi.c (bidi_level_of_next_char):
11826 * xdisp.c (get_visually_first_element): Remove old incorrect
11827 comments regarding the Unicode Line Separator character.
11829 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11831 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11833 * alloc.c (Fgc_status): Do not access beyond zombies array
11834 boundary if nzombies > MAX_ZOMBIES.
11835 * alloc.c (dump_zombies): Add missing format specifier.
11837 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11839 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11840 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11842 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11843 Some packages use them to denote characters with modifiers.
11845 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11847 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11848 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11849 matching a pp-number. Rename parameter var to var1.
11851 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11853 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11855 2011-10-08 Glenn Morris <rgm@gnu.org>
11857 * callint.c (Fcall_interactively): Give a more explicit error for the
11858 'c' case with a non-character input. (Bug#8479)
11860 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11862 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11864 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11865 lines that are hscrolled on the left.
11867 * dispnew.c (buffer_posn_from_coords): Account for a possible
11868 presence of header-line. (Bug#4426)
11870 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11872 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11873 Don't advertise functionality which we discourage or doesn't work.
11875 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11877 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11878 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11879 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11880 this makes Emacs dump core during garbage collection on rare
11881 occasions. sizeof is obviously inferior to offsetof here, so
11882 stick with offsetof.
11883 (GC_POINTER_ALIGNMENT): New macro.
11884 (mark_memory): Omit 3rd (offset) arg; caller changed.
11885 Don't assume EMACS_INT alignment is the same as pointer alignment.
11887 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11889 * keyboard.c (read_key_sequence_remapped): New var.
11890 (read_key_sequence): Compute remapping in the right buffer.
11891 (command_loop_1): Use read_key_sequence's remapping directly.
11893 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11895 * dired.c (file_name_completion): Don't expand file name.
11896 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11897 before checking file name handler.
11899 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11900 they've been requested explicitly (bug#9591).
11902 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11904 * keymap.c (Fsingle_key_description): Use make_specified_string
11905 instead of build_string to build string from push_key_description.
11908 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11910 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11911 This fixes a Y2038 bug on 64-bit hosts.
11912 * buffer.c (reset_buffer):
11913 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11914 (Fclear_buffer_auto_save_failure):
11915 Use 0, not -1, to represent an unset failure time, since time_t
11916 might not be signed.
11918 Remove dependency on glibc malloc internals.
11919 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11920 Move back here from lisp.h, but with their new implementations.
11921 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11922 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11923 * charset.c (charset_table_init): New static var.
11924 (syms_of_charset): Use it instead of xmalloc. This removes a
11925 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11926 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11927 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11928 Move back to alloc.c.
11929 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11930 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11932 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11934 * nsterm.m (windowDidResize): Call x_set_window_size only when
11935 ns_in_resize is true. Otherwise set pixelwidth/height and
11936 call change_frame_size (Bug#9628).
11938 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11940 Port --enable-checking=all to Fedora 14 x86-64.
11941 * charset.c (syms_of_charset): Also account for glibc malloc's
11942 internal overhead when calculating the initial malloc maximum.
11944 Port --enable-checking=all to Fedora 14 x86.
11945 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11947 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
11948 (overrun_check_realloc, overrun_check_free):
11949 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
11950 That way, xmalloc returns a properly-aligned pointer even if
11951 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
11952 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
11953 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
11954 into account when calculating the initial malloc maximum.
11955 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11956 Move here from alloc.c, so that charset.c can use it too.
11957 Properly align; the old code wasn't right for common 32-bit hosts
11958 when configured with --enable-checking=all.
11959 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11960 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
11962 2011-09-29 Eli Zaretskii <eliz@gnu.org>
11964 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
11967 2011-09-28 Eli Zaretskii <eliz@gnu.org>
11969 * xdisp.c (compute_display_string_end): If there's no display
11970 string at CHARPOS, return -1.
11972 * bidi.c (bidi_fetch_char): When compute_display_string_end
11973 returns a negative value, treat the character as a normal
11974 character not covered by a display string. (Bug#9624)
11976 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
11978 * lread.c (Fread_from_string): Fix typo in docstring.
11980 2011-09-27 Eli Zaretskii <eliz@gnu.org>
11982 * xdisp.c (handle_invisible_prop): If invisible text ends on a
11983 newline, reseat the iterator instead of bidi-iterating there one
11984 character at a time. (Bug#9610)
11985 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
11986 TO_CHARPOS if the bidi iterator is at base embedding level.
11988 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
11990 * lread.c (readevalloop): Use correct code for NBSP.
11991 (read1): Likewise. (Bug#9608)
11993 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
11995 * dbusbind.c (Fdbus_register_signal): When service is not
11996 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
11998 2011-09-25 Glenn Morris <rgm@gnu.org>
12000 * buffer.c (truncate-lines): Doc fix.
12002 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12004 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12005 (Fset_window_next_buffers): Doc fix.
12007 2011-09-24 Glenn Morris <rgm@gnu.org>
12009 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12011 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12013 Fix minor problems found by static checking.
12014 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12015 * indent.c (Fvertical_motion): Fix == vs = typo.
12017 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12019 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12020 Default value is now t. Doc fix.
12022 * indent.c (Fvertical_motion): Compute and apply the overshoot
12023 logic when moving up, not only when moving down. Fix the
12024 confusing name and values of the it_overshoot_expected variable;
12025 logic changes accordingly. (Bug#9254) (Bug#9549)
12027 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12028 CHARPOS is covered by a display string which includes newlines.
12029 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12030 is covered by a display string with embedded newlines.
12032 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12034 * dbusbind.c (Fdbus_register_signal): Add match rule to
12035 Vdbus_registered_objects_table. (Bug#9581)
12036 (Fdbus_register_method, Vdbus_registered_objects_table):
12039 2011-09-24 Jim Meyering <meyering@redhat.com>
12041 do not ignore write error for any output size
12042 The previous change was incomplete.
12043 While it makes emacs --batch detect the vast majority of stdout
12044 write failures, errors were still ignored whenever the output size is
12045 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12046 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12047 && echo FAIL: ignored write error
12048 FAIL: ignored write error
12049 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12050 && echo FAIL: ignored write error
12051 FAIL: ignored write error
12052 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12054 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12056 * emacs.c (Fkill_emacs): In noninteractive mode exit
12057 non-successfully if a write error occurred on stdout. (Bug#9574)
12059 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12061 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12064 * dispextern.h (struct it): Update the comment documenting what
12067 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12069 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12070 a display string, extend search for cursor position to end of row.
12071 (find_row_edges): If the row ends in a newline from a display
12072 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12073 Handle the case of a display string with multiple newlines.
12074 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12075 non-empty line. Fixes confusing cursor motion with arrow keys at
12076 the beginning of a line that starts with whitespace.
12078 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12080 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12083 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12085 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12086 boolean (Bug#9154).
12088 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12090 * xdisp.c (display_line): Record maximum and minimum buffer
12091 positions even if no glyphs were produced (e.g., by a zero-width
12092 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12093 buffer positions that will be removed from the glyph row because
12095 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12096 column is beyond frame width: don't subtract 1 "pixel" when
12097 computing width of the stretch.
12098 (reseat_at_next_visible_line_start): Undo the change made on
12099 2011-09-17 that saved paragraph information and restored it after
12100 the call to `reseat'. (Bug#9545)
12102 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12104 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12105 and turn window cursor on if cleared (Bug#9415).
12107 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12109 * search.c (boyer_moore): Take unibyte characters from pattern
12110 literally. (Bug#9458)
12112 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12114 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12116 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12118 Fix minor problem found by static checking.
12119 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12120 initialized, to pacify gcc -Wuninitialized.
12122 * fileio.c: Report proper errno when syscall falls.
12123 (Finsert_file_contents): Save and restore errno,
12124 so that report_file_error outputs the correct diagnostic.
12125 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12127 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12129 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12131 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12133 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12134 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12136 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12138 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12139 about the current paragraph and restore it after the call to reseat.
12141 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12142 (bidi_find_paragraph_start): Search back for paragraph beginning
12143 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12144 (bidi_move_to_visually_next): Only trigger paragraph-related
12145 computations when the last character is a newline or at EOB, not
12146 just any NEUTRAL_B. (Bug#9470)
12148 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12149 truncated lines if point is covered by a display string. (Bug#9524)
12151 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12153 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12154 (cons_to_x_long): New function.
12155 (lisp_data_to_selection_data): Use it. Correct the test for
12156 short-versus-long data; it was negated. Break out of vector
12157 loop, for efficiency, when a long datum is discovered.
12159 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12161 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12163 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12165 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12166 GCC PR/17406) by declaring this function with external scope.
12168 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12170 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12171 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12173 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12175 * editfns.c (Fformat): Correctly handle text properties on "%%".
12177 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12179 * xterm.c (x_draw_composite_glyph_string_foreground):
12180 * w32term.c (x_draw_composite_glyph_string_foreground):
12181 * term.c (encode_terminal_code):
12182 * composite.c (composition_update_it, get_composition_id):
12183 * xdisp.c (get_next_display_element)
12184 (fill_composite_glyph_string): Add comments about special meaning
12185 of TAB characters in a composition.
12187 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12189 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12190 This occurs when processing a multibyte format.
12191 Problem reported by Wolfgang Jenker.
12193 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12195 * xdisp.c (try_cursor_movement): Only check for exact match if
12196 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12198 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12200 Remove unused external symbols.
12201 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12202 * xdisp.c (calc_pixel_width_or_height): Now static.
12203 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12204 * indent.c (check_display_width):
12205 * w32term.c: Fix comment to match code.
12206 * xterm.c, xterm.h (x_catching_errors): Remove.
12208 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12210 * xselect.c: Use signed conversions more consistently (Bug#9498).
12211 (selection_data_to_lisp_data): Assume incoming selection data are
12212 signed integers, not unsigned. This is to be consistent with
12213 outgoing selection data, which was modified to use signed integers
12214 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12215 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12216 expects long, not unsigned long.
12218 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12220 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12221 computation of loop end. Reported by Johan Bockgård
12224 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12226 * frame.c (Fother_visible_frames_p): Function deleted.
12228 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12230 * indent.c (compute_motion): Process display vector front to back
12231 rather than the other way around. (Bug#2496)
12233 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12235 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12237 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12239 * minibuf.c (Fread_from_minibuffer): Doc fix.
12241 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12243 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12244 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12246 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12248 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12249 value for non-existent files.
12251 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12253 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12254 set its "size" to -1. This will set the modtime_size field of
12255 the corresponding buffer to -1, which is what
12256 verify-visited-file-modtime expects for files that do not exist.
12259 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12261 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12263 * lisp.h: ... from here. push_key_description is no longer
12264 defined in keyboard.c, so its declaration should not be in
12265 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12266 logically belongs with push_key_description.
12268 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12270 * buffer.h: Include <sys/types.h> instead of <time.h>.
12271 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12272 Problem reported by Herbert J. Skuhra.
12274 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12276 * xml.c (parse_region): Make the parsing work for
12277 non-comment-starting XML files again (bug#9144).
12279 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12281 * image.c (gif_load): Fix calculation of bottom and right corner.
12284 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12286 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12287 redisplay in small windows.
12289 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12291 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12293 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12295 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12296 Operate on live windows only.
12298 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12300 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12302 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12304 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12305 only under bidi iteration.
12307 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12309 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12311 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12313 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12314 Without this fix, the command to link temacs failed due to an
12315 undefined symbol __builtin_isnan. This is because
12316 /usr/include/iso/math_c99.h #defines isnan(x) to
12317 __builtin_isnan(x), but the bundled gcc, which identifies itself
12318 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12320 * floatfns.c (isnan): #undef, and then #define to a clone of
12322 (Fisnan): Always define, since it's always available now.
12323 (syms_of_floatfns): Always define isnan at the Lisp level.
12325 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12327 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12329 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12331 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12332 The previous code assumed that file offsets (off_t values) fit in
12333 EMACS_INT variables, which is not true on typical 32-bit hosts.
12334 The code messed up by falsely reporting buffer overflow in cases
12335 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12336 when "big" contains more than 2**29 bytes, even though this
12337 inserts just one byte and does not overflow the buffer.
12338 (Finsert_file_contents): Store file offsets as off_t
12339 values, not as EMACS_INT values. Check for overflow when
12340 converting between EMACS_INT and off_t. When checking for
12341 buffer overflow or for overlap, take the offsets into account.
12342 Don't use EMACS_INT for small values where int suffices.
12343 When checking for overlap, fix a typo: ZV was used where
12344 ZV_BYTE was intended.
12345 (Fwrite_region): Don't assume off_t fits into 'long'.
12346 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12348 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12350 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12352 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12354 sprintf-related integer and memory overflow issues (Bug#9412).
12356 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12357 (esprintf, exprintf, evxprintf): New functions.
12358 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12359 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12360 (modify_event_symbol): Do not assume that the length of
12361 name_alist_or_stem is safe to alloca and fits in int.
12362 (Fexecute_extended_command): Likewise for function name and binding.
12363 (Frecursion_depth): Wrap around reliably on integer overflow.
12364 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12365 since some callers pass EMACS_INT values.
12366 (Fsingle_key_description): Don't crash if symbol name contains more
12367 than MAX_ALLOCA bytes.
12368 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12369 (get_minibuffer): Arg is now EMACS_INT, not int.
12370 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12371 (esprintf, exprintf, evxprintf): New decls.
12372 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12374 * dbusbind.c (signature_cat): New function.
12375 (xd_signature, Fdbus_register_signal):
12376 Do not overrun buffer; instead, report string overflow.
12378 * dispnew.c (add_window_display_history): Don't overrun buffer.
12379 Truncate instead; this is OK since it's just a log.
12381 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12382 even if the time zone offset is outlandishly large.
12383 Don't mishandle offset == INT_MIN.
12385 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12386 when creating daemon; the previous buffer-overflow check was incorrect.
12388 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12389 which has the guts of the old verror function.
12391 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12392 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12394 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12395 (font_unparse_xlfd): Don't blindly alloca long strings.
12396 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12397 fits in int, when using sprintf. Use single snprintf to count
12398 length of string rather than counting it via multiple sprintfs;
12399 that's simpler and more reliable.
12400 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12401 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12402 sprintf, in case result does not fit in int.
12404 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12405 (fontset_from_font): Print it.
12407 * frame.c (tty_frame_count): Now printmax_t, not int.
12408 (make_terminal_frame, set_term_frame_name): Print it.
12409 (x_report_frame_params): In X, window IDs are unsigned long,
12410 not signed long, so print them as unsigned.
12411 (validate_x_resource_name): Check for implausibly long names,
12412 and don't assume name length fits in 'int'.
12413 (x_get_resource_string): Don't blindly alloca invocation name;
12414 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12417 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12418 (xg_check_special_colors, xg_set_geometry):
12419 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12421 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12422 Use esprintf, not sprintf, in case result does not fit in int.
12424 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12425 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12426 it as a large positive number.
12427 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12428 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12430 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12431 in case result does not fit in int.
12433 * print.c (float_to_string): Detect width overflow more reliably.
12434 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12435 buffer overrun. Don't assume list length fits in 'int'. Treat
12436 print length of 0 as 0, not as infinity; to be consistent with other
12437 uses of print length in this function. Don't overflow print length
12438 index. Don't assume hash table size fits in 'long', or that
12439 vectorlike size fits in 'unsigned long'.
12441 * process.c (make_process): Use printmax_t, not int, to format
12442 process-name gensyms.
12444 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12446 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12447 to avoid potential buffer overrun.
12449 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12450 if X resource line is longer than 512 bytes.
12452 * xfns.c (x_window): Make sprintf buffer a bit bigger
12453 to avoid potential buffer overrun.
12455 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12457 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12459 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12461 Integer overflow fixes for scrolling, etc.
12462 Without these, Emacs silently mishandles large integers sometimes.
12463 For example, "C-u 4294967297 M-x recenter" was treated as if
12464 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12466 * xdisp.c (try_window_id): Check Emacs fixnum range before
12467 converting to 'int'.
12469 * window.c (window_scroll_line_based, Frecenter):
12470 Check that an Emacs fixnum is in range before assigning it to 'int'.
12471 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12472 values converted from Emacs fixnums.
12473 (Frecenter): Don't wrap around a line count if it is out of 'int'
12474 range; instead, treat it as an extreme value.
12475 (Fset_window_configuration, compare_window_configurations):
12476 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12478 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12479 that can exceed INT_MAX. Check that EMACS_INT value is in range
12480 before assigning it to the (possibly-narrower) index.
12481 (match_limit): Don't assume that a fixnum can fit in 'int'.
12483 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12486 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12487 (Fvertical_motion): Don't wrap around LINES values that don't fit
12488 in 'int'. Instead, treat them as extreme values. This is good
12489 enough for windows, which can't have more than INT_MAX lines anyway.
12491 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12493 * Require libxml/parser.h to avoid compilation warning.
12495 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12497 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12498 since this reportedly can destroy thread storage.
12500 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12502 * syntax.c (find_defun_start): Update all cache variables if
12503 exiting early (Bug#9401).
12505 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12507 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12509 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12510 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12511 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12513 * term.c (tty_append_glyph): New function.
12514 (produce_stretch_glyph): Static function and its prototype deleted.
12516 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12519 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12521 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12522 when checking :margin (Bug#9390).
12523 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12524 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12525 so that the name doesn't mislead. All uses changed.
12527 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12529 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12532 2011-08-27 Eli Zaretskii <eliz@gnu.org>
12534 * xdisp.c (move_it_to): Don't bail out early when reaching
12535 position beyond to_charpos, if we are scanning backwards.
12536 (move_it_vertically_backward): When DY == 0, make sure we get to
12537 the first character in the line after the newline.
12539 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12541 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12542 (ccl_driver): Do not generate an out-of-range pointer.
12543 (Fccl_execute_on_string): Remove unnecessary check for
12544 integer overflow, noted by Stefan Monnier in
12545 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12546 Remove a FIXME that didn't need fixing.
12547 Simplify the newly-introduced buffer reallocation code.
12549 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12551 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12553 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12555 Integer and memory overflow issues (Bug#9196).
12557 * doc.c (get_doc_string): Rework so that
12558 get_doc_string_buffer_size is the actual buffer size, rather than
12559 being 1 less than the actual buffer size; this makes xpalloc more
12562 * image.c (x_allocate_bitmap_record, cache_image):
12563 * xselect.c (Fx_register_dnd_atom):
12564 Simplify previous changes by using xpalloc.
12566 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12567 since either will do and ptrdiff_t is convenient with xpalloc.
12569 * charset.c (charset_table_size)
12570 (struct charset_sort_data.priority): Now ptrdiff_t.
12571 (charset_compare): Don't overflow if priorities differ greatly.
12572 (Fsort_charsets): Don't assume list length fits in int.
12573 Check for size-calculation overflow when allocating sort data.
12574 (syms_of_charset): Allocate an initial charset table that is
12575 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12577 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12579 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12580 The actual value is always <= INT_MAX, and leaving it unsigned made
12581 overflow checking harder.

12595 (revalidate_region_cache, know_region_cache, region_cache_forward)
12596 (region_cache_backward, pp_cache):
12597 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12598 so that ptrdiff_t * can be passed to xpalloc.

12617 Don't update size of array until after memory allocation succeeds,
12618 because xmalloc/xrealloc may not return.
12619 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12620 now that we have proper integer overflow checking.

12624 * callproc.c (Fcall_process): Check for size overflow when

12631 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

12671 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12673 * emacs.c (main): Do not reallocate argv, since there is a null at
12674 the end that can be overwritten, and this way there's no need to
12675 worry about size-calculation overflow.
12676 (sort_args): Check for size-calculation overflow.
12678 * eval.c (init_eval_once, grow_specpdl): Don't update size until

12685 (x_set_alpha): Do not assume XINT fits in int.
12687 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12688 This is for the members text_lines, text_cols, total_lines, total_cols,
12689 where the system imposes an 'int' limit.

12698 Check for size-calculation overflow.
12699 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12700 do, as we prefer signed integers.

12805 (X_LONG_MIN): New macros.
12806 Use them to make the following changes clearer.
12807 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

12810 (SELECTION_QUANTUM): Remove, replacing with ...
12811 (selection_quantum): ... new function, which avoids overflow.
12813 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

12831 Don't store size until memory allocation succeeds.
12832 (x_get_window_property): Plug memory leak on memory exhaustion.
12833 Don't double-block input; malloc is safe here. Don't assume 2**34
12834 - 4 fits in unsigned long. Add an xassert to check
12835 XGetWindowProperty overflow. Be more careful about overflow
12836 calculations, and distinguish size from memory overflow better.

12927 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12928 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12929 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12930 length, not size_t. Use ptrdiff_t for index, not int.
12931 (keyremap_step, read_key_sequence): Redo bufsize check to avoid

12960 Prefer int to unsigned where either will do.
12961 (tiff_handler): New function, combining the cores of the
12962 old tiff_error_handler and tiff_warning_handler.

12964 stack buffer overflows. It uses only the features of vsnprintf
12965 that are common to both POSIX and native Microsoft.
12966 (tiff_error_handler, tiff_warning_handler): Use it.
12967 (tiff_load, gif_load, imagemagick_load_image):

13008 2011-08-24 Eli Zaretskii <eliz@gnu.org>
13010 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
13011 buffers, return left-to-right.
13012 (set_cursor_from_row): Consider candidate row a win if its glyph
13013 represents a newline and point is on that newline. Fixes cursor
13014 positioning on the newline at EOL of R2L text within L2R
13015 paragraph, and vice versa.
13016 (try_cursor_movement): Check continued rows, in addition to
13017 continuation rows. Fixes unwarranted scroll when point enters a
13018 continued line of R2L text within an L2R paragraph, or vice versa.
13019 (cursor_row_p): Consider the case of point being equal to
13020 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13021 from the end of a short line to the beginning of a continued line
13022 of R2L text within L2R paragraph.
13023 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

13041 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
13042 extra slot even if the purpose is char-code-property-table.
13044 2011-08-23 Eli Zaretskii <eliz@gnu.org>
13046 * xdisp.c (redisplay_window): When computing centering_position,
13047 account for the height of the header line. (Bug#8874)
13049 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13050 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13051 candidate is selected by the mouse, and that candidate has a
13052 composed character under the mouse.
13054 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13055 coordinates reported by pos-visible-in-window-p for a composed
13056 character in column zero.
13058 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
13060 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
13062 2011-08-22 Eli Zaretskii <eliz@gnu.org>
13064 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
13065 consider it a hit if to_charpos is anywhere in the range of the
13066 composed buffer positions.
13068 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13070 * image.c (gif_load): Don't assume that each subimage has the same
13071 dimensions as the base image. Handle disposal method that is
13072 "undefined" by the gif spec (Bug#9335).
13074 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13076 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
13077 (Fcondition_case): Document `debug' symbol in error handler.
13079 2011-08-19 Eli Zaretskii <eliz@gnu.org>
13081 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
13082 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13083 from an Org mode buffer to a Speedbar frame.
13085 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13086 a composition, take its buffer position from IT->cmp_it.charpos.
13087 Fixes cursor positioning at the beginning of a line that begins
13088 with a composed character.
13090 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13092 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13093 character bidirectional type, use STRONG_L instead. Fixes crashes
13094 in a buffer produced by `describe-categories'.
13096 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13097 members before the level stack, so they would be saved and
13098 restored when copying iterator state. Fixes incorrect reordering
13099 around TABs covered by display properties.
13101 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
13103 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
13105 2011-08-17 Chong Yidong <cyd@stupidchicken.com>

13108 (internal_condition_case_2, internal_condition_case_n):
13109 Remove unnecessary aborts (Bug#9081).
13111 2011-08-17 Eli Zaretskii <eliz@gnu.org>
13113 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
13114 has no `load' handler, try opening the file locally. (Bug#9311)
13116 2011-08-16 Ken Brown <kbrown@cornell.edu>
13118 * gmalloc.c: Expand comment.
13120 2011-08-16 Eli Zaretskii <eliz@gnu.org>

13169 after the pid of the process is set to -1 (Bug#8162).
13171 2011-08-14 Eli Zaretskii <eliz@gnu.org>
13173 * xdisp.c (move_it_in_display_line_to): Don't invoke
13174 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
13175 ppos_it. Fixes vertical cursor motion when line beginning is
13176 covered by an image. (Bug#9296)
13178 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
13180 * nsterm.h (ns_run_ascript): Declare.

13184 (ns_run_ascript): New function.
13185 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
13186 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
13187 the event loop. Get status from as_status (Bug#7276).
13189 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13190 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13191 the event loop (Bug#7276).
13193 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
13195 * gnutls.c (QCgnutls_bootprop_priority)

13197 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
13198 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)

13217 (Fnetwork_interface_list): Allocate in increments of bytes instead
13218 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13219 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
13221 (struct ifflag_def): notrailers is smart on OSX.
13222 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
13223 Get hardware address with getifaddrs if available.
13225 2011-08-12 Eli Zaretskii <eliz@gnu.org>
13227 * xdisp.c (iterate_out_of_display_property): xassert that
13228 IT->position is set to within IT->object's boundaries. Break from
13229 the loop as soon as EOB is reached; avoids infloops in redisplay
13230 when IT->position is set up wrongly due to some bug.
13231 Set IT->current to match the bidi iterator unconditionally.
13232 (push_display_prop): Allow GET_FROM_STRING as IT->method on
13233 entry. Force push_it to save on the stack the current
13234 buffer/string position, to be restored by pop_it. Fix flags in
13235 the iterator structure wrt the object coming from a display
13236 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13237 properties. (Bug#9284)
13239 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
13241 * fontset.c (fontset_get_font_group): Add proper type checks.

13271 2011-08-07 Juri Linkov <juri@jurta.org>
13273 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
13274 to show the arg `TIME' instead of `TIMEVAL'.
13276 2011-08-06 Eli Zaretskii <eliz@gnu.org>
13278 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
13279 display property strides EOL and includes a newline, as in
13280 longlines-mode. (Bug#9254)
13281 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
13282 word-wrap under bidirectional display. (Bug#9224)
13284 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
13285 is non-zero, even if the data buffer is NULL. Fixes a crash in
13286 vertical-motion with longlines-mode. (Bug#9254)
13288 2011-08-05 Eli Zaretskii <eliz@gnu.org>
13290 * bidi.c <bidi_cache_total_alloc>: Now static.

13293 * xdisp.c (display_line): Release buffer allocated for shelved bidi
13296 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
13297 amount allocated this far in `bidi_cache_total_alloc'.
13298 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
13299 non-zero, only free the data buffer without restoring the cache
13300 contents. All callers changed.
13302 * dispextern.h (bidi_unshelve_cache): Update prototype.
13304 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

13307 to xfree to an equivalent call to bidi_unshelve_cache.
13308 (move_it_in_display_line_to): Fix logic of returning
13309 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)

13364 * bidi.c (bidi_fetch_char): Accept an additional argument
13365 DISP_PROP_P, and pass it to compute_display_string_pos.
13366 Only handle text covered by a display string if DISP_PROP_P is returned
13367 non-zero. All callers of bidi_fetch_char changed.
13369 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

13401 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
13402 This is needed if max-image-size is a floating-point number.

13454 Without this fix, if a signal arrives just after memory fills up,
13455 'malloc' might be invoked reentrantly.
13457 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13458 In other words, assume that every image size is allowed, on non-X
13459 hosts. This assumption is probably wrong, but it lets Emacs compile.

13483 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13484 (bidi_find_other_level_edge):
13485 Use ptrdiff_t instead of EMACS_INT where either will do.
13486 This works better on 32-bit hosts configured --with-wide-int.
13487 (bidi_cache_ensure_space): Check for size-calculation overflow.
13488 Use % rather than repeated addition, for better worst-case speed.
13489 Don't set bidi_cache_size until after xrealloc returns, because it
13491 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13492 (bidi_cache_ensure_space): Also check that the bidi cache size
13493 does not exceed that of the largest Lisp string or buffer. See Eli
13494 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13496 * alloc.c (__malloc_size_t): Remove.
13497 All uses replaced by size_t. See Andreas Schwab's note
13498 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13500 * image.c: Improve checking for integer overflow.
13501 (check_image_size): Assume that f is nonnull, since
13502 it is always nonnull in practice. This is one less thing to
13503 worry about when checking for integer overflow later.
13504 (x_check_image_size): New function, which checks for integer
13505 overflow issues inside X.
13506 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13507 This removes the need for a memory_full check.
13508 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13509 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13510 (xbm_read_bitmap_data): Change locals back to 'int', since
13511 their values must fit in 'int'.
13512 (xpm_load_image, png_load, tiff_load):
13513 Invoke x_create_x_image_and_pixmap earlier,
13514 to avoid much needless work if the image is too large.
13515 (tiff_load): Treat overly large images as if
13516 x_create_x_image_and_pixmap failed, not as malloc failures.
13517 (gs_load): Use x_check_image_size.
13519 * gtkutil.c: Omit integer casts.
13520 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13521 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13523 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13525 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13526 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13527 would wrongly return t on a 64-bit host.
13529 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13530 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13531 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13532 and therefore cause GCC to emit a bogus diagnostic in some cases.
13534 * image.c: Integer signedness and overflow and related fixes.
13535 This is not an exhaustive set of fixes, but it's time to
13536 record what I've got.
13537 (lookup_pixel_color, check_image_size): Remove redundant decls.
13538 (check_image_size): Don't assume that arbitrary EMACS_INT values
13539 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13540 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13541 (tiff_load, imagemagick_load_image):
13542 Check for overflow in size calculations.
13543 (x_create_x_image_and_pixmap): Remove unnecessary test for
13544 xmalloc returning NULL; that can't happen.
13545 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13546 (xpm_color_bucket): Use better integer hashing function.
13547 (xpm_cache_color): Don't possibly over-allocate memory.
13548 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13549 (gif_memory_source):
13550 Use ptrdiff_t, not int or size_t, to record sizes.
13551 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13552 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13553 either works, as we prefer signed integers.
13554 (tiff_read_from_memory, tiff_write_from_memory):
13555 Return tsize_t, not size_t, since that's what the TIFF API wants.
13556 (tiff_read_from_memory): Don't fail simply because the read would
13557 go past EOF; instead, return a short read.
13558 (tiff_load): Omit no-longer-needed casts.
13559 (Fimagemagick_types): Don't assume size fits into 'int'.
13561 Improve hashing quality when configured --with-wide-int.
13562 * fns.c (hash_string): New function, taken from sxhash_string.
13563 Do not discard information about ASCII character case; this
13564 discarding is no longer needed.
13565 (sxhash-string): Use it. Change sig to match it. Caller changed.
13566 * lisp.h: Declare it.
13567 * lread.c (hash_string): Remove, since we now use fns.c's version.
13568 The fns.c version returns a wider integer if --with-wide-int is
13569 specified, so this should help the quality of the hashing a bit.
13571 * emacs.c: Integer overflow minor fix.
13572 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13573 Define only if GNU_LINUX.
13574 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13576 * dispnew.c: Integer signedness and overflow fixes.
13577 Remove unnecessary forward decls, that were a maintenance hassle.
13578 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13580 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13581 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13582 (prepare_desired_row, line_draw_cost):
13583 Use int, not unsigned, where either works.
13584 (save_current_matrix, restore_current_matrix):
13585 Use ptrdiff_t, not size_t, where either works.
13586 (init_display): Check for overflow more accurately, and without
13587 relying on undefined behavior.
13589 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13590 Remove, replacing with the new symbols in lisp.h. All uses changed.
13591 * fileio.c (make_temp_name):
13592 * filelock.c (lock_file_1, lock_file):
13593 * xdisp.c (message_dolog):
13594 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13595 Use pMd etc. instead.
13596 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13597 replacing the pWIDE etc. symbols removed from editfns.c.
13599 * keyboard.h (num_input_events): Now uintmax_t.
13600 This is (very slightly) less likely to mess up due to wraparound.
13603 * buffer.c: Integer signedness fixes.
13604 (alloc_buffer_text, enlarge_buffer_text):
13605 Use ptrdiff_t rather than size_t when either will do, as we prefer
13608 * alloc.c: Integer signedness and overflow fixes.
13609 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13610 (__malloc_size_t): Default to size_t, not to int.
13611 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13612 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13613 Prefer ptrdiff_t to size_t when either would do, as we prefer
13615 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13616 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13617 Now const. Initialize with values that are in range even if char
13619 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13620 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13621 These functions do the right thing with sizes > 2**32.
13622 (check_depth): Now ptrdiff_t, not int.
13623 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13624 Adjust to new way of storing sizes. Check for size overflow bugs
13626 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13627 slightly wrong anyway, as it missed one instance of
13628 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13629 (refill_memory_reserve): Omit needless cast to size_t.
13630 (mark_object_loop_halt): Mark as externally visible.
13632 * xselect.c: Integer signedness and overflow fixes.
13633 (Fx_register_dnd_atom, x_handle_dnd_message):
13634 Use ptrdiff_t, not size_t, since we prefer signed.
13635 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13636 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13637 x_dnd_atoms_size and x_dnd_atoms_length.
13639 * doprnt.c: Prefer signed to unsigned when either works.
13641 * doprnt.c (doprnt):
13643 * xdisp.c (vmessage):
13644 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13645 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13646 prefer signed arithmetic to avoid comparison confusion.
13647 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13648 but is a bit tricky.
13650 Assume freestanding C89 headers, string.h, stdlib.h.
13651 * data.c, doprnt.c, floatfns.c, print.c:
13652 Include float.h unconditionally.
13653 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13654 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13655 * regex.c: Likewise for stddef.h, string.h.
13656 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13657 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13658 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13659 (STDC_HEADERS): Remove obsolete defines.
13660 * sysdep.c: Include limits.h unconditionally.
13662 Assume support for memcmp, memcpy, memmove, memset.
13663 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13664 * regex.c (memcmp, memcpy):
13665 Remove; we assume C89 now.
13667 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13668 (__malloc_safe_bcopy): Remove; no longer needed.
13670 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13671 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13672 well either way, and we prefer signed to unsigned.
13674 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13676 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13677 closes the connection while we're reading (bug#9182).
13679 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13681 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13682 are specified (Bug#9168).
13684 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13686 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13687 Found by GCC static checking and --with-wide-int on a 32-bit host.
13689 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13691 * xdisp.c (compute_display_string_pos): Fix logic of caching
13692 previous display string position. Initialize cached_prev_pos to
13693 -1. Fixes slow-down at the beginning of a buffer.
13695 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13697 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13698 for attrs[LFACE_FONTSET_INDEX].
13700 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13702 * xml.c (parse_region): Remove unused local
13703 that was recently introduced.
13705 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13707 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13708 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13710 * xdisp.c (move_it_in_display_line_to): Record the best matching
13711 position for TO_CHARPOS while scanning the line, and restore it on
13712 exit if none of the characters scanned was an exact match.
13713 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13714 when exact match is impossible due to invisible text, and the
13715 lines are truncated.
13717 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13719 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13722 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13724 Fix a significant slow-down of cursor motion with C-n, C-p,
13725 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13726 auto-repeat under bidi redisplay in fontified buffers.
13727 * xdisp.c (compute_stop_pos_backwards): New function.
13728 (next_element_from_buffer): Call compute_stop_pos_backwards to
13729 find a suitable prev_stop when we find ourselves before
13731 (reseat): Don't look for prev_stop, as that could mean a very long
13733 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13734 <cached_disp_overlay_modiff>: Cache for last found display string
13736 (compute_display_string_pos): Return the cached position if asked
13737 about the same buffer in the same area of character positions, and
13738 the buffer wasn't changed since the time the display string
13739 position was cached.
13741 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13743 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13744 is an integer, which is important for empty lines. (Bug#9149)
13746 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13748 * frame.c (Fmodify_frame_parameters): In tty case, update the
13749 default face if necessary (Bug#4238).
13751 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13753 * editfns.c (Fstring_to_char): No need to explain what a character
13754 is in the docstring (Bug#6576).
13756 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13758 * xml.c (parse_region): Make sure we always return a tree.
13760 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13762 * xml.c (parse_region): If a document contains only comments,
13765 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13767 * xml.c (make_dom): Return comments, too.
13769 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13772 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13773 and the surrounding thread.
13774 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13775 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13776 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13778 * s/openbsd.h (BROKEN_SIGIO): Define.
13779 * unexelf.c (unexec) [__OpenBSD__]:
13780 Don't update the .mdebug section of the Alpha COFF symbol table.
13782 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13784 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13787 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13789 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13790 This fixes some race conditions on the permissions of any newly
13793 * alloc.c (valid_pointer_p): Use pipe, not open.
13794 This fixes some permissions issues when debugging.
13796 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13797 If fchown fails to set both uid and gid, try to set just gid,
13798 as that is sometimes allowed. Adjust the file's mode to eliminate
13799 setuid or setgid bits that are inappropriate if fchown fails.
13801 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13803 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13804 to compare Lisp_Objects.
13805 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
13806 global_gnutls_log_level, don't mistake it for a Lisp_Object.
13807 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
13809 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13811 * lread.c (read_integer): Unread even EOF character.
13812 (read1): Likewise. Properly record start position of symbol.
13814 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13815 symbol character follows.
13817 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13819 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13820 This works around a problem with the previous change to Fcopy_file.
13821 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13822 and without this change, GCC might complain about discarding
13823 fchown's return value.
13825 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13827 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13829 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13831 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13833 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13835 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13836 it's used from the C level.
13838 * process.c: Use the same condition for POLL_FOR_INPUT in both
13839 keyboard.c and process.c (bug#1858).
13841 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13843 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13844 (Fgnutls_boot): Use it.
13846 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13848 * doc.c (Fsubstitute_command_keys): Revert last change.
13850 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13852 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13853 quotes the next character, and doesn't affect other longer
13854 sequences (bug#8935).
13856 * lread.c (syms_of_lread): Clarify that is isn't only
13857 `eval-buffer' and `eval-defun' that's affected by
13858 `lexical-binding' (bug#8460).
13860 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13862 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13863 bidi redisplay when a line includes both an image and is truncated.
13865 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13867 Fix minor problems found by static checking.
13868 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13869 (elsz): Now a signed constant, not a size_t var. We prefer signed
13870 types to unsigned, to avoid integer comparison confusion. Without
13871 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
13872 "cannot optimize loop, the loop counter may overflow", a symptom
13874 * indent.c (Fvertical_motion): Mark locals as initialized.
13875 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
13877 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
13879 * search.c (Fre_search_backward): Mention `case-fold-search' in
13880 all the re_search_* functions (bug#8138).
13882 * keyboard.c (Fopen_dribble_file): Document when the file is
13885 2011-07-14 Eli Zaretskii <eliz@gnu.org>
13887 * bidi.c (bidi_dump_cached_states): Fix format of displaying
13890 Support bidi reordering of display and overlay strings.
13891 * xdisp.c (compute_display_string_pos)
13892 (compute_display_string_end): Accept additional argument STRING.
13893 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
13894 (reseat_to_string): Initialize bidi_it->string.s and
13895 bidi_it->string.schars.
13896 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
13897 NULL (avoids a crash in bidi_paragraph_init).
13898 Initialize itb.string.lstring.
13899 (init_iterator): Call bidi_init_it only of a valid
13900 buffer position was specified. Initialize paragraph_embedding to
13902 (reseat_to_string): Initialize the bidi iterator.
13903 (display_string): If we need to ignore text properties of
13904 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
13905 original value of -1 will not work with bidi.)
13906 (compute_display_string_pos): First arg is now struct
13907 `text_pos *'; all callers changed. Support display properties on
13909 (compute_display_string_end): Support display properties on Lisp
13911 (init_iterator, reseat_1, reseat_to_string): Initialize the
13912 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
13913 when iterating on a string not from display properties).
13914 (compute_display_string_pos, compute_display_string_end):
13915 Fix calculation of the object to scan. Fixes an error when using
13917 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
13918 base_level_stop; instead, set base_level_stop to BEGV.
13919 Fixes crashes in vertical-motion.
13920 (next_element_from_buffer): Improve commentary for when
13921 the iterator is before prev_stop.
13922 (init_iterator): Initialize bidi_p from the default value of
13923 bidi-display-reordering, not from buffer-local value. Use the
13924 buffer-local value only if initializing for buffer iteration.

14399 (clone_per_buffer_values): Don't assume that
14400 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
14401 This isn't true in general, and it's particularly not true
14402 if Emacs is configured with --with-wide-int.
14403 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
14404 New macros, used in the buffer.c change.

14440 Random fixes. E.g., (random) never returned negative values.
14441 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14442 subseconds part to the entropy, as that's a bit more random.
14443 Prefer signed to unsigned, since the signedness doesn't matter and
14444 in general we prefer signed. When given a limit, use a
14445 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14446 latter isn't right if USE_2_TAGS_FOR_INTS.
14447 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14448 not 0..VALMASK. Don't discard "excess" bits that random () returns.
14450 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
14452 * textprop.c (text_property_stickiness):
14453 Obey Vtext_property_default_nonsticky.

14460 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14461 This is more efficient than Ffile_directory_p and avoids a minor race.
14463 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
14465 * buffer.c (Foverlay_put): Say what the return value is
14468 * fileio.c (barf_or_query_if_file_exists): Check first if the file
14469 is a directory before asking whether to use the file name
14471 (barf_or_query_if_file_exists): Make the "File is a directory"
14472 error be more correct.
14474 * fns.c (Frequire): Remove the mention of the .gz files, since
14475 that's installation-specific, but keep the mention of
14476 `get-load-suffixes'.

14480 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

14488 Qgnutls_bootprop_verify_error (which is no longer used).
14490 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
14491 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
14492 Also (re)move comments that are misplaced or no longer relevant.
14494 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14496 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

14555 (syms_of_keymap): Defsubr make-composed-keymap.
14556 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

14593 * eval.c (struct backtrace): Simplify and port the data structure.
14594 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14595 signed bit field, as this assumption is not portable and it makes
14596 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14597 "char debug_on_exit : 1" as this is not portable either; instead,
14598 use the portable "unsigned int debug_on_exit : 1". Remove unused
14599 member evalargs. Remove obsolete comments about cc bombing out.
14601 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

14803 Now ptrdiff_t, not int.
14804 (read1): Don't assume doc string length fits in int. Check for
14805 out-of-range doc string lengths.
14806 (read_list): Don't assume file position fits in int.
14807 (read_escape): Check for hex character overflow.
14809 2011-06-22 Leo Liu <sdl.web@gmail.com>
14811 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14812 Move to minibuffer.el.
14814 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14816 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14817 The following patches are for when GLYPH_DEBUG && !XASSERT.
14818 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14819 * dispnew.c (flush_stdout):
14820 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14821 Mark as externally visible.
14822 * dispnew.c (check_window_matrix_pointers): Now static.
14823 * dispnew.c (window_to_frame_vpos):
14824 * xfns.c (unwind_create_frame):
14825 * xterm.c (x_check_font): Remove unused local.
14826 * scroll.c (CHECK_BOUNDS):
14827 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14828 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14829 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14830 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14831 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14833 (debug_method_add): Use va_list and vsprintf rather than relying
14834 on undefined behavior with wrong number of arguments.
14835 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14836 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14837 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14838 since we're not interested in debugging glyphs with old libraries.
14839 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14840 GCC 4.6.0's static checking.
14842 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14844 Integer overflow and signedness fixes (Bug#8873).

14853 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
14854 (x_create_bitmap_from_xpm_data):
14855 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
14856 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
14858 * xfaces.c (load_pixmap):
14859 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
14860 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14861 (.bitmaps_last, struct x_output.icon_bitmap):
14862 Use ptrdiff_t, not int, for bitmap indexes.
14863 (x_allocate_bitmap_record): Check for size overflow.
14864 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14866 Use ptrdiff_t, not int, for overlay counts.
14867 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14868 * editfns.c (overlays_around, get_pos_property):
14869 * textprop.c (get_char_property_and_overlay):
14870 * xdisp.c (next_overlay_change, note_mouse_highlight):
14871 * xfaces.c (face_at_buffer_position):
14872 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14873 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14874 (Fnext_overlay_change, Fprevious_overlay_change)
14875 (mouse_face_overlay_overlaps, Foverlays_in):
14876 Use ptrdiff_t, not int, for sizes.
14877 (overlays_at, overlays_in): Check for size-calculation overflow.
14879 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14881 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14882 (x_session_initialize): Do not assume string length fits in int.
14884 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14885 This is unlikely, but can occur if DPI is outlandish.
14887 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14888 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14890 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14891 * xrdb.c (magic_file_p, search_magic_path):
14892 Omit last arg SUFFIX; it was always 0. All callers changed.
14893 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14895 * xfont.c (xfont_match): Avoid need for strlen.
14897 * xfns.c: Don't assume strlen fits in int.
14898 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
14900 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14901 not unsigned long, as we prefer signed integers. All callers changed.
14902 Detect integer overflow in repeat count.
14903 (message_dolog): Don't assume print length fits in 39 bytes.
14904 (display_mode_element): Don't assume strlen fits in int.
14906 * termcap.c: Don't assume sizes fit in int and never overflow.
14907 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14908 (gobble_line): Check for size-calculation overflow.
14910 * minibuf.c (Fread_buffer):
14911 * lread.c (intern, intern_c_string):
14912 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
14913 Don't assume string length fits in int.
14915 * keyboard.c (parse_tool_bar_item):
14916 * gtkutil.c (style_changed_cb): Avoid need for strlen.
14918 * font.c: Don't assume string length fits in int.
14919 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
14920 Use ptrdiff_t, not int.
14921 (font_intern_prop): Don't assume string length fits in int.
14922 Don't assume integer property fits in fixnum.
14923 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14925 * filelock.c: Fix some buffer overrun and integer overflow issues.
14926 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14927 Reformulate so as not to need the command string.
14928 Invoke gzip -cd rather than gunzip, as it's more portable.
14929 (lock_info_type, lock_file_1, lock_file):
14930 Don't assume pid_t and time_t fit in unsigned long.
14931 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14932 (current_lock_owner): Prefer signed type for sizes.
14933 Use memcpy, not strncpy, where memcpy is what is really wanted.
14934 Don't assume (via atoi) that time_t and pid_t fit in int.
14935 Check for time_t and/or pid_t out of range, e.g., via a network share.
14936 Don't alloca where an auto var works fine.
14938 * fileio.c: Fix some integer overflow issues.
14939 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
14940 Don't assume string length fits in int.
14941 (directory_file_name): Don't assume string length fits in long.
14942 (make_temp_name): Don't assume pid fits in int, or that its print
14943 length is less than 20.
14945 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
14947 * coding.c (make_subsidiaries): Don't assume string length fits in int.
14949 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
14951 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
14952 We prefer signed integers, even for size calculations.
14954 * emacs.c: Don't assume string length fits in 'int'.
14955 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
14956 (main): Don't invoke strlen when not needed.
14958 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
14959 (XD_DEBUG_MESSAGE): Don't waste a byte.
14961 * callproc.c (getenv_internal_1, getenv_internal)
14962 (Fgetenv_internal):
14963 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
14965 * lread.c (invalid_syntax): Omit length argument.
14966 All uses changed. This doesn't fix a bug, but it simplifies the
14967 code away from its former Hollerith-constant appearance, and it's
14968 one less 'int' to worry about when looking at integer-overflow issues.
14969 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
14971 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
14972 This didn't break anything, but it didn't help either.
14973 It's confusing to put a bogus integer in a place where the actual
14974 value does not matter.
14975 (LIST_END_P): Remove unused macro and its bogus comment.
14976 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
14978 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
14979 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
14981 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
14982 We prefer signed types, and the value cannot exceed the EMACS_INT
14983 range anyway (because otherwise the length would not be representable).
14984 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
14985 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
14986 This avoids a GCC warning when WIDE_EMACS_INT.
14988 * indent.c (sane_tab_width): New function.
14989 (current_column, scan_for_column, Findent_to, position_indentation)
14990 (compute_motion): Use it. This is just for clarity.
14991 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
14993 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
14995 * lisp.h (lint_assume): New macro.
14996 * composite.c (composition_gstring_put_cache):
14997 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
14999 * editfns.c, insdel.c:
15000 Omit unnecessary forward decls, to simplify future changes.
15002 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15004 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15006 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15007 Use much-faster test for byte-length change.
15008 Don't assume string byte-length fits in 'int'.
15009 Check that character arg fits in 'int'.
15010 (mapcar1): Declare byte as byte, for clarity.
15012 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15014 * fns.c (concat): Catch string overflow earlier.
15015 Do not rely on integer wraparound.
15017 * dispextern.h (struct it.overlay_strings_charpos)
15018 (struct it.selective): Now EMACS_INT, not int.
15019 * xdisp.c (forward_to_next_line_start)
15020 (back_to_previous_visible_line_start)
15021 (reseat_at_next_visible_line_start, next_element_from_buffer):
15022 Don't arbitrarily truncate the value of 'selective' to int.
15024 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15026 * composite.c: Don't truncate sizes to 'int'.
15027 (composition_gstring_p, composition_reseat_it)
15028 (composition_adjust_point): Use EMACS_INT, not int.
15029 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15030 not EMACS_UINT, for indexes.
15032 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15034 * buffer.c: Include <verify.h>.
15035 (struct sortvec.priority, struct sortstr.priority):
15036 Now EMACS_INT, not int.
15037 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15038 (struct sortstr.size, record_overlay_string)
15039 (struct sortstrlist.size, struct sortlist.used):
15040 Don't truncate size to int.
15041 (record_overlay_string): Check for size-calculation overflow.
15042 (init_buffer_once): Check at compile-time, not run-time.
15044 2011-06-22 Jim Meyering <meyering@redhat.com>
15046 Don't leak an XBM-image-sized buffer
15047 * image.c (xbm_load): Free the image buffer after using it.
15049 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15052 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15053 that Sun C diagnosed.
15054 * fns.c (secure_hash): Fix pointer signedness issue.
15055 * intervals.c (static_offset_intervals): New function.
15056 (offset_intervals): Use it.
15058 2011-06-21 Leo Liu <sdl.web@gmail.com>
15061 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15064 * fns.c (secure_hash): Rename from crypto_hash_function and change
15065 the first arg to accept symbols.
15066 (Fsecure_hash): New primitive.
15067 (syms_of_fns): New symbols.
15069 2011-06-20 Deniz Dogan <deniz@dogan.se>
15071 * process.c (Fset_process_buffer): Clarify return value in
15074 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15076 * dispnew.c (add_window_display_history): Use BVAR.
15078 * xdisp.c (debug_method_add): Use BVAR.
15079 (check_window_end, dump_glyph_matrix, dump_glyph)
15080 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15082 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15085 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15086 check till after the cache is created in init_frame_faces.
15088 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15090 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15092 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15094 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15095 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15096 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15098 Improve buffer-overflow checking (Bug#8873).
15099 * fileio.c (Finsert_file_contents):
15100 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15101 Remove the old (too-loose) buffer overflow checks.
15102 They weren't needed, since make_gap checks for buffer overflow.
15103 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15104 The old code merely checked for Emacs fixnum overflow, and relied
15105 on undefined (wraparound) behavior. The new code avoids undefined
15106 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15108 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15109 Tune. Don't use wider integers than needed. Don't use alloca.
15110 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15112 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15114 * insdel.c, lisp.h (buffer_overflow): New function.
15115 (insert_from_buffer_1, replace_range, replace_range_2):
15116 * insdel.c (make_gap_larger):
15117 * editfns.c (Finsert_char):
15118 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15120 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15122 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15124 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15126 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15127 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15129 * fileio.c: Don't assume EMACS_INT fits in off_t.
15130 (emacs_lseek): New static function.
15131 (Finsert_file_contents, Fwrite_region): Use it.
15132 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15134 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15136 * fns.c: Don't overflow int when computing a list length.
15137 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15138 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15139 truncation on 64-bit hosts. Check for QUIT every
15140 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15141 faster and is responsive enough.
15142 (Flength): Report an error instead of overflowing an integer.
15143 (Fsafe_length): Return a float if the value is not representable
15144 as a fixnum. This shouldn't happen except in contrived situations.
15145 (Fnthcdr, Fsort): Don't assume list length fits in int.
15146 (Fcopy_sequence): Don't assume vector length fits in int.
15148 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15149 (header_size, word_size): New constants.
15150 (allocate_vectorlike): Don't check size overflow here.
15151 (allocate_vector): Check it here instead, since this is the only
15152 caller of allocate_vectorlike that could cause overflow.
15153 Check that the new vector's length is representable as a fixnum.
15155 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15156 The previous code was bogus. For example, next_almost_prime (32)
15157 returned 39, which is undesirable as it is a multiple of 3; and
15158 next_almost_prime (24) returned 25, which is a multiple of 5 so
15159 why was the code bothering to check for multiples of 7?
15161 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15163 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15165 Variadic C functions now count arguments with ptrdiff_t.
15166 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15167 Back then I didn't know that the Emacs coding style prefers signed int.
15168 Also, in the meantime I found a few more instances where arguments
15169 were being counted with int, which may truncate counts on 64-bit
15170 machines, or EMACS_INT, which may be unnecessarily wide.
15171 * lisp.h (struct Lisp_Subr.function.aMANY)
15172 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15173 Arg counts are now ptrdiff_t, not size_t.
15174 All variadic functions and their callers changed accordingly.
15175 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15176 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15177 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15178 * callint.c (Fcall_interactively): Check arg count for overflow,
15179 to avoid potential buffer overrun. Use signed char, not 'int',
15180 for 'varies' array, so that we needn't bother to check its size
15181 calculation for overflow.
15182 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15183 * eval.c (apply_lambda):
15184 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15185 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15186 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15188 * callint.c (Fcall_interactively): Don't use index var as event count.
15190 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15191 * mem-limits.h (SIZE): Remove; no longer used.
15193 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15195 Remove unnecessary casts.
15196 * xterm.c (x_term_init):
15197 * xfns.c (x_set_border_pixel):
15198 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15199 These aren't needed now that we assume ANSI C.
15201 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15202 It's more likely to cause problems (due to unsigned overflow)
15205 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15207 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15209 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15211 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15213 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15215 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15217 GLYPH_CODE_FACE returns EMACS_INT, not int.
15218 * dispextern.h (merge_faces):
15219 * xfaces.c (merge_faces):
15220 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15221 Don't assume EMACS_INT fits in int.
15223 * character.h (CHAR_VALID_P): Remove unused parameter.
15224 * fontset.c, lisp.h, xdisp.c: All uses changed.
15226 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15228 * fns.c (concat): Minor tuning based on overflow analysis.
15229 This doesn't fix any bugs. Use int to hold character, instead
15230 of constantly refetching from Emacs object. Use XFASTINT, not
15231 XINT, for value known to be a character. Don't bother comparing
15232 a single byte to 0400, as it's always less.
15234 * floatfns.c (Fexpt):
15235 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15237 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15240 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15242 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15243 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15244 incorrectly succeed when S was a string, because 4294967386 was
15245 truncated before it was used.
15247 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15248 Otherwise, an out-of-range integer could cause undefined behavior
15251 * composite.c: Use int, not EMACS_INT, for characters.
15252 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15253 EMACS_INT, for values that are known to be in character range.
15254 This doesn't fix any bugs but is the usual style inside Emacs and
15255 may generate better code on 32-bit machines.
15257 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15258 This is for reasons similar to the recent CHAR_STRING fix.
15259 * charset.c (Fencode_char): Check that character arg is actually
15260 a character. Pass an int to ENCODE_CHAR.
15261 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15262 wider than 'int', as a compile-time check to prevent future regressions
15265 * character.c (char_string): Remove unnecessary casts.
15267 Make sure a 64-bit char is never passed to CHAR_STRING.
15268 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15269 by silently ignoring the top 32 bits, allowing some values
15270 that were far too large to be valid characters.
15271 * character.h: Include <verify.h>.
15272 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15273 arguments are no wider than unsigned, as a compile-time check
15274 to prevent future regressions in this area.
15276 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15277 (Fsubst_char_in_region):
15279 * xdisp.c (decode_mode_spec_coding):
15280 Adjust to CHAR_STRING's new requirement.
15281 * editfns.c (Finsert_char, Fsubst_char_in_region):
15282 * fns.c (concat): Check that character args are actually
15283 characters. Without this test, these functions did the wrong
15284 thing with wildly out-of-range values on 64-bit hosts.
15286 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15287 These casts should not be needed on 32-bit hosts, either.
15288 * keyboard.c (read_char):
15289 * lread.c (Fload): Remove casts to unsigned.
15291 * lisp.h (UNSIGNED_CMP): New macro.
15292 This fixes comparison bugs on 64-bit hosts.
15293 (ASCII_CHAR_P): Use it.
15294 * casefiddle.c (casify_object):
15295 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15296 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15297 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15298 * dispextern.h (FACE_FROM_ID):
15299 * keyboard.c (read_char): Use UNSIGNED_CMP.
15301 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15302 not to EMACS_INT, to avoid GCC warning.
15304 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15306 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15307 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15308 isn't needed on 32-bit machines.
15310 * buffer.c (Fgenerate_new_buffer_name):
15311 Use EMACS_INT for count, not int.
15312 (advance_to_char_boundary): Return EMACS_INT, not int.
15314 * data.c (Qcompiled_function): Now static.
15316 * window.c (window_body_lines): Now static.
15318 * image.c (gif_load): Rename local to avoid shadowing.
15320 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15321 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15322 * alloc.c (make_save_value): Integer argument is now of type
15323 ptrdiff_t, not int.
15324 (mark_object): Use ptrdiff_t, not int.
15325 * lisp.h (pD): New macro.
15326 * print.c (print_object): Use it.
15328 * alloc.c: Use EMACS_INT, not int, to count objects.
15329 (total_conses, total_markers, total_symbols, total_vector_size)
15330 (total_free_conses, total_free_markers, total_free_symbols)
15331 (total_free_floats, total_floats, total_free_intervals)
15332 (total_intervals, total_strings, total_free_strings):
15333 Now EMACS_INT, not int. All uses changed.
15334 (Fgarbage_collect): Compute overall total using a double, so that
15335 integer overflow is less likely to be a problem. Check for overflow
15336 when converting back to an integer.
15337 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15338 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15339 These were 'int' variables that could overflow on 64-bit hosts;
15340 they were never used, so remove them instead of repairing them.
15341 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15342 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15343 Previously, this ceilinged at INT_MAX, but that doesn't work on
15345 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15347 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15348 (allocate_vectorlike): Check for ptrdiff_t overflow.
15349 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15350 when a (possibly-narrower) signed value would do just as well.
15351 We prefer using signed arithmetic, to avoid comparison confusion.
15353 * alloc.c: Catch some string size overflows that we were missing.
15354 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15355 for convenience in STRING_BYTES_MAX.
15356 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15357 The definition here is exact; the one in lisp.h was approximate.
15358 (allocate_string_data): Check for string overflow. This catches
15359 some instances we weren't catching before. Also, it catches
15360 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15361 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15362 and ptrdiff_t and EMACS_INT are both 64 bits.
15364 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15365 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15366 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15368 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15370 * alloc.c (Fmake_string): Check for out-of-range init.
15372 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15374 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15376 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15378 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15379 xg_get_default_scrollbar_width.
15381 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
15382 (int_gtk_range_get_value): Move to the scroll bar part of the file.
15383 (style_changed_cb): Call update_theme_scrollbar_width and call
15384 x_set_scroll_bar_default_width and xg_frame_set_char_size for
15385 all frames (Bug#8505).
15386 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
15387 Call gtk_window_set_resizable if HAVE_GTK3.
15388 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
15389 and height if HAVE_GTK3 (Bug#8505).
15390 (scroll_bar_width_for_theme): New variable.
15391 (update_theme_scrollbar_width): New function.
15392 (xg_get_default_scrollbar_width): Move code to
15393 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
15394 (xg_initialize): Call update_theme_scrollbar_width.
15396 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
15398 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
15400 2011-06-12 Martin Rudalics <rudalics@gmx.at>
15402 * frame.c (make_frame): Call other_buffer_safely instead of
15405 * window.c (temp_output_buffer_show): Call display_buffer with
15406 second argument Vtemp_buffer_show_specifiers and reset latter
15407 immediately after the call.
15408 (Vtemp_buffer_show_specifiers): New variable.
15409 (auto_window_vscroll_p, next_screen_context_lines)
15410 (Vscroll_preserve_screen_position): Remove leading asterisks from

16006 * gnutls.c: Use Emacs's memory allocators.
16007 Without this change, the gnutls library would invoke malloc etc.
16008 directly, which causes problems on non-SYNC_INPUT hosts, and which
16009 runs afoul of improving memory_full behavior. (Bug#8761)
16010 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16011 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16012 xfree instead of the default malloc, realloc, free.
16013 (Fgnutls_boot): No need to check for memory allocation failure,
16014 since xmalloc does that for us.

16038 * alloc.c (allocate_vectorlike):
16039 Check for overflow in vector size calculations.
16040 * ccl.c (ccl_driver):
16041 Check for overflow when converting EMACS_INT to int.

16043 need to be updated by these changes.
16044 * fns.c (make_hash_table, maybe_resize_hash_table):
16045 Check for integer overflow with large hash tables.
16046 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16047 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16048 (SXHASH_REDUCE): New macro.
16049 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16050 Use it instead of discarding useful hash info with large hash values.
16051 (sxhash_float): New function.
16052 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16053 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16054 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16055 Rewrite to use FIXNUM_BITS, as this simplifies things.
16056 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16057 Adjust signatures to match updated version of code.
16058 (consing_since_gc): Now EMACS_INT, since a single hash table can
16059 use more than INT_MAX bytes.

16102 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16103 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16104 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16106 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16108 Make it possible to run ./temacs.
16110 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16111 syms_of_callproc does the same thing. Remove test for
16112 "initialized", do it in the caller.
16113 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16115 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16117 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16118 (read_minibuf): Use get_minibuffer.
16119 (syms_of_minibuf): Use DEFSYM.
16120 (Qmetadata): New var.
16121 * data.c (Qbuffer): Don't make it static.
16122 (syms_of_data): Use DEFSYM.
16124 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16126 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
16127 (CCL_CODE_MIN): New macro.
16129 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16131 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16133 * eval.c (Qdebug): Now static.
16134 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16135 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
16136 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
16138 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16140 * image.c: Various fixes to ImageMagick code comments.
16141 (Fimagemagick_types): Doc fix.
16143 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16145 Minor fixes prompted by GCC 4.6.0 warnings.
16147 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16149 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16150 (x_clipboard_manager_save_all): Move extern decl to ...
16151 * xterm.h: ... here, so that it can be checked for consistency.
16153 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16155 * xselect.c (x_clipboard_manager_save_frame)
16156 (x_clipboard_manager_save_all): New functions.
16157 (Fx_clipboard_manager_save): Lisp function deleted.
16159 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16160 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16162 * xterm.h: Update prototype.
16164 2011-05-28 William Xu <william.xwl@gmail.com>
16166 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16167 exiting (Bug#8239).
16169 2011-05-28 Jim Meyering <meyering@redhat.com>
16171 Avoid a sign-extension bug in crypto_hash_function.
16172 * fns.c (to_uchar): Define.
16173 (crypto_hash_function): Use it to convert some newly-signed
16174 variables to unsigned, to avoid sign-extension bugs. For example,
16175 without this change, (md5 "truc") would evaluate to
16176 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16177 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16178 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16180 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16182 Integer overflow fixes.
16184 * dbusbind.c: Serial number integer overflow fixes.
16185 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16186 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16187 to hold a serial number that is too large for a fixnum.
16188 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16189 Check for serial numbers out of range. Decode any serial number
16190 that was so large that it became a float. (Bug#8722)
16192 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16193 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16194 Use XFASTINT rather than XUINT when numbers are nonnegative.
16195 (xd_append_arg, Fdbus_method_return_internal):
16196 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16197 arguments, check that Lisp number is nonnegative, rather than
16198 silently wrapping negative numbers around. (Bug#8722)
16199 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16202 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16204 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16206 ccl: Add integer overflow checks.
16207 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16208 (IN_INT_RANGE): New macros.
16209 (ccl_driver): Use them to check for integer overflow when
16210 decoding a CCL program. Many of the new checks are whether XINT (x)
16211 fits in int; it doesn't always, on 64-bit hosts. The new version
16212 doesn't catch all possible integer overflows, but it's an
16213 improvement. (Bug#8719)
16215 * alloc.c (make_event_array): Use XINT, not XUINT.
16216 There's no need for unsigned here.
16218 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16219 This follows up to the 2011-05-06 change that substituted uintptr_t
16220 for EMACS_INT. This case wasn't caught back then.
16222 Rework Fformat to avoid integer overflow issues.
16223 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16224 now (part of C89). Include <verify.h>.
16225 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16226 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16227 (Fformat): Avoid the prepass trying to compute sizes; it was only
16228 approximate and thus did not catch overflow reliably. Instead, walk
16229 through the format just once, formatting and computing sizes as we go,
16230 checking for integer overflow at every step, and allocating a larger
16231 buffer as needed. Keep track separately whether the format is
16232 multibyte. Keep only the most-recently calculated precision, rather
16233 than them all. Record whether each argument has been converted to
16234 string. Use EMACS_INT, not int, for byte and char and arg counts.
16235 Support field widths and precisions larger than INT_MAX. Avoid
16236 sprintf's undefined behavior with conversion specifications such as %#d
16237 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16238 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16239 formatting out-of-range floating point numbers with int
16240 formats. (Bug#8668)
16242 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16244 * data.c: Avoid integer truncation in expressions involving floats.
16245 * data.c: Include <intprops.h>.
16246 (arith_driver): When there's an integer overflow in an expression
16247 involving floating point, convert the integers to floating point
16248 so that the resulting value does not suffer from catastrophic
16249 integer truncation. For example, on a 64-bit host (* 4
16250 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16251 Do not rely on undefined behavior after integer overflow.
16253 merge count_size_as_multibyte, parse_str_to_multibyte
16254 * character.c, character.h (count_size_as_multibyte):
16255 Rename from parse_str_to_multibyte; all uses changed.
16256 Check for integer overflow.
16257 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16258 since it's now a duplicate of the other. This is more of
16259 a character than a buffer op, so better that it's in character.c.
16260 * fns.c, print.c: Adjust to above changes.
16262 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16264 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16266 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16268 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16269 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16270 (x_clipboard_manager_save): Now static.
16271 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16273 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16274 (crypto_hash_function): Now static.
16275 Fix pointer signedness problems. Avoid unnecessary initializations.
16277 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16279 * termhooks.h (Vselection_alist): Make it terminal-local.
16281 * terminal.c (create_terminal): Initialize it.
16283 * xselect.c: Support for clipboard managers.
16284 (Vselection_alist): Move to termhooks.h as terminal-local var.
16285 (LOCAL_SELECTION): New macro.
16286 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16287 (symbol_to_x_atom): Remove gratuitous arg.
16288 (x_handle_selection_request, lisp_data_to_selection_data)
16289 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16290 (x_own_selection, x_get_local_selection, x_convert_selection):
16291 New arg, specifying work frame. Use terminal-local Vselection_alist.
16292 (some_frame_on_display): Delete unused function.
16293 (Fx_own_selection_internal, Fx_get_selection_internal)
16294 (Fx_disown_selection_internal, Fx_selection_owner_p)
16295 (Fx_selection_exists_p): New optional frame arg.
16296 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16297 (x_handle_selection_clear): Don't treat other terminals with the
16298 same keyboard specially. Use the terminal-local Vselection_alist.
16299 (x_clear_frame_selections): Use Frun_hook_with_args.
16301 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16303 * xterm.h: Add support for those atoms.
16305 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16307 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16308 (converted_selections, conversion_fail_tag): New global variables.
16309 (x_selection_request_lisp_error): Free the above.
16310 (x_get_local_selection): Remove unnecessary code.
16311 (x_reply_selection_request): Args changed; handle arbitrary array
16312 of converted selections stored in converted_selections.
16313 Separate the XChangeProperty and SelectionNotify steps.
16314 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16315 (x_convert_selection): New function.
16316 (x_handle_selection_event): Simplify.
16317 (x_get_foreign_selection): Don't ignore incoming requests while
16318 waiting for an answer; this will fail when we implement
16319 SAVE_TARGETS, and seems unnecessary anyway.
16320 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16321 (Vx_sent_selection_functions): Doc fix.
16323 2011-05-26 Leo Liu <sdl.web@gmail.com>
16325 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16327 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16329 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16331 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16332 for fringe update if it has periodic bitmap.
16333 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16334 and fringe_bitmap_periodic_p.
16336 * fringe.c (get_fringe_bitmap_data): New function.
16337 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16338 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16339 row. Mark glyph row for fringe update if periodicity changed.
16341 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16342 for fringe update unless it has periodic bitmap.
16344 2011-05-25 Kenichi Handa <handa@m17n.org>
16346 * xdisp.c (get_next_display_element): Set correct it->face_id for
16347 a static composition.
16349 2011-05-24 Leo Liu <sdl.web@gmail.com>
16352 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16354 * fns.c (crypto_hash_function, Fsha1): New function.
16355 (Fmd5): Use crypto_hash_function.
16356 (syms_of_fns): Add Ssha1.
16358 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16360 * gnutls.c: Remove unused macros.
16361 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16362 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16363 Remove macros that are defined and never used.
16364 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16366 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16368 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16369 (Fx_get_selection_internal): Minor cleanup.
16370 (Fx_own_selection_internal): Rename arguments for consistency with
16373 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16375 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16377 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16379 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16381 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16383 * dispnew.c (scrolling_window): Don't exclude the case that the
16384 last enabled row in the desired matrix touches the bottom boundary.
16386 2011-05-21 Glenn Morris <rgm@gnu.org>
16388 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16389 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16390 and add some more files.
16392 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16394 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16395 report_file_error introduced by the change from 2011-05-07.
16397 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16399 * systime.h (Time): Define only if emacs is defined.
16400 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16401 where the include path doesn't have X11/X.h by default. See
16402 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16404 2011-05-20 Kenichi Handa <handa@m17n.org>
16406 * composite.c (find_automatic_composition): Fix previous change.
16408 2011-05-20 Glenn Morris <rgm@gnu.org>
16410 * lisp.mk: New file, split from Makefile.in.
16411 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16412 (shortlisp): Remove.
16413 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16415 2011-05-19 Glenn Morris <rgm@gnu.org>
16417 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16418 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16419 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16420 (lisp): Set the order to that of loadup.el.
16421 (shortlisp): Make it a copy of $lisp.
16422 (SOME_MACHINE_LISP): Remove.
16423 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16424 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16426 2011-05-18 Kenichi Handa <handa@m17n.org>
16428 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16429 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16430 (find_automatic_composition): Mostly rewrite for efficiency.
16432 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16434 * makefile.w32-in: Update dependencies.
16436 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16438 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16439 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16441 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16443 Fix some integer overflow issues, such as string length overflow.
16445 * insdel.c (count_size_as_multibyte): Check for string overflow.
16447 * character.c (lisp_string_width): Check for string overflow.
16448 Use EMACS_INT, not int, for string indexes and lengths; in
16449 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16450 the resulting string length overflows an EMACS_INT; instead,
16451 report a string overflow if no precision given. When checking for
16452 precision exhaustion, use a check that cannot possibly have
16453 integer overflow. (Bug#8675)
16454 * character.h (lisp_string_width): Adjust to new signature.
16456 * alloc.c (string_overflow): New function.
16457 (Fmake_string): Use it. This doesn't change behavior, but saves
16458 a few bytes and will simplify future changes.
16459 * character.c (string_escape_byte8): Likewise.
16460 * lisp.h (string_overflow): New decl.
16462 Fixups, following up to the user-interface timestamp change.
16463 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16464 for UI timestamps, instead of unsigned long.
16465 * msdos.c (mouse_get_pos): Likewise.
16466 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16467 * w32gui.h (Time): Define by including "systime.h" rather than by
16468 declaring it ourselves. (Bug#8664)
16470 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16471 * image.c (clear_image_cache): Likewise.
16473 * term.c (term_mouse_position): Don't assume time_t wraparound.
16475 Be more systematic about user-interface timestamps.
16476 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16477 and sometimes 'EMACS_UINT', to represent these timestamps.
16478 This change causes it to use 'Time' uniformly, as that's what X uses.
16479 This makes the code easier to follow, and makes it easier to catch
16480 integer overflow bugs such as Bug#8664.
16481 * frame.c (Fmouse_position, Fmouse_pixel_position):
16482 Use Time, not unsigned long, for user-interface timestamps.
16483 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16484 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16485 * keyboard.h (last_event_timestamp): Likewise.
16486 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16487 * menu.h (xmenu_show): Likewise.
16488 * term.c (term_mouse_position): Likewise.
16489 * termhooks.h (struct input_event.timestamp): Likewise.
16490 (struct terminal.mouse_position_hook): Likewise.
16491 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16492 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16493 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16494 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16495 what it was before.
16496 * menu.h, termhooks.h: Include "systime.h", for Time.
16498 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16499 Don't assume that the difference between two unsigned long values
16500 can fit into an integer. At this point, we know button_down_time
16501 <= event->timestamp, so the difference must be nonnegative, so
16502 there's no need to cast the result if double-click-time is
16503 nonnegative, as it should be; check that it's nonnegative, just in
16504 case. This bug is triggered when events are more than 2**31 ms
16505 apart (about 25 days). (Bug#8664)
16507 * xselect.c (last_event_timestamp): Remove duplicate decl.
16508 (x_own_selection): Remove needless cast to unsigned long.
16510 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16511 that always fit in int. Use a sentinel instead of a counter, to
16512 avoid a temp and to allay GCC's concerns about possible int overflow.
16513 * frame.h (struct frame): Use int for menu_bar_items_used
16514 instead of EMACS_INT, since it always fits in int.
16516 * menu.c (grow_menu_items): Check for int overflow.
16518 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16520 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16521 Before, the code was not consistent. These values cannot exceed
16522 2**31 - 1 so there's no need to make them unsigned.
16523 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16524 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16525 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16527 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16529 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16530 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16531 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16532 presumably because the widths might not match.
16534 * window.c (size_window): Avoid needless test at loop start.
16536 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16538 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16540 2011-05-12 Drew Adams <drew.adams@oracle.com>
16542 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16544 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16546 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16547 `width' to `bar_area_x' and `bar_area_width', respectively.
16548 (x_scroll_run): Take account of fringe background extension.
16550 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16551 Rename local vars `left' and `width' to `bar_area_x' and
16552 `bar_area_width', respectively.
16553 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16554 background extension.
16556 2011-05-10 Jim Meyering <meyering@redhat.com>
16558 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16560 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16562 * image.c (Finit_image_library): Return t for built-in image types,
16563 like pbm and xbm. (Bug#8640)
16565 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16567 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16569 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16571 * w32console.c (Fset_screen_color): Doc fix.
16572 (Fget_screen_color): New function.
16573 (syms_of_ntterm): Defsubr it.
16575 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16576 unlink the temporary file if Fcall_process didn't create it in the
16578 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16579 child process will be redirected to a file specified with `:file'.
16580 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16581 cue to call_process_cleanup not to close that handle.
16583 2011-05-07 Ben Key <bkey76@gmail.com>
16585 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16586 one of two shell specific rules, either bootstrap-temacs-CMD or
16587 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16588 to the previous implementation of the bootstrap-temacs rule.
16589 The bootstrap-temacs-CMD rule is similar to the previous
16590 implementation of the bootstrap-temacs rule except that it
16591 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16594 These changes, along with some changes to nt/configure.bat,
16595 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16596 earlier fix to add support for --cflags and --ldflags options
16597 that include quotes so that it works whether make uses cmd or
16600 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16602 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16603 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16605 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16606 a string. Handle both cases.
16607 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16608 (Fdbus_register_method): Use Qinvalid_function.
16610 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16612 * makefile.w32-in: Update dependencies.
16613 (LISP_H): Add inttypes.h and stdin.h.
16614 (PROCESS_H): Add unistd.h.
16616 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16618 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16619 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16621 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16623 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16625 * term.c (vfatal): Remove stray call to va_end.
16626 It's not needed and the C Standard doesn't allow it here anyway.
16628 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16629 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16631 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16634 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16636 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16638 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16640 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16642 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16644 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16645 * charset.c (Fdefine_charset_internal): Don't initialize
16646 charset.code_space[15]. The value was garbage, on hosts with
16647 32-bit int (Bug#8600).
16649 * lread.c (read_integer): Be more consistent with string-to-number.
16650 Use string_to_number to do the actual conversion; this avoids
16651 rounding errors and fixes some other screwups. Without this fix,
16652 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16653 (digit_to_number): Move earlier, for benefit of read_integer.
16654 Return -1 if the digit is out of range for the base, -2 if it is
16655 not a digit in any supported base. (Bug#8602)
16657 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16659 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16660 to match comment at start of function. This also removes a
16661 GCC warning about overflow in a 32+64-bit port.
16663 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16665 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16666 Reported by Stefan Monnier in
16667 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16668 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16669 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16671 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16672 (EMACS_UINTPTR): Likewise, with uintptr_t.
16674 * lisp.h: Prefer 64-bit EMACS_INT if available.
16675 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16676 on 32-bit hosts that have 64-bit int, so that they can access
16678 However, temporarily disable this change unless the temporary
16679 symbol WIDE_EMACS_INT is defined.
16681 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16683 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16684 This removes an assumption that EMACS_INT and long are the same
16685 width as pointers. The assumption is true for Emacs porting targets
16686 now, but we want to make other targets possible.
16687 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16688 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16689 In the rest of the code, change types of integers that hold casted
16690 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16691 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16692 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16693 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16694 No need to cast type when ORing.
16695 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16696 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16697 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16698 assume EMACS_INT is the same width as char *.
16699 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16700 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16701 Remove no-longer-needed casts.
16702 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16703 (xg_tool_bar_help_callback, xg_make_tool_item):
16704 Use EMACS_INTPTR to hold an integer
16705 that will be cast to void *; this can avoid a GCC warning
16706 if EMACS_INT is not the same width as void *.
16707 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16708 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16709 (current_message_1, set_message_1):
16710 Use a local to convert to proper width without a cast.
16711 * xmenu.c (dialog_selection_callback): Likewise.
16713 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16714 Also, don't assume VALBITS / RAND_BITS is less than 5,
16715 and don't rely on undefined behavior when shifting a 1 left into
16717 * lisp.h (get_random): Change signature to match.
16719 * lread.c (hash_string): Use size_t, not int, for hash computation.
16720 Normally we prefer signed values; but hashing is special, because
16721 it's better to use unsigned division on hash table sizes so that
16722 the remainder is nonnegative. Also, size_t is the natural width
16723 for hashing into memory. The previous code used 'int', which doesn't
16724 retain enough info to hash well into very large tables.
16725 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16727 * dbusbind.c: Don't possibly lose pointer info when converting.
16728 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16729 Use XPNTR rather than XHASH, so that the high-order bits of
16730 the pointer aren't lost when converting through void *.
16732 * eval.c (Fautoload): Don't double-shift a pointer.
16734 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16736 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16738 * gnutls.c (DEF_GNUTLS_FN):
16739 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16741 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16743 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16746 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16748 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16749 New version that can reserve upto 2GB of heap space.
16751 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16753 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

16757 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16758 `gnutls_certificate_set_x509_key_file'.
16760 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16762 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16763 Update dependencies.
16765 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16767 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16768 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16769 Remove unused parameter `fildes'.
16770 * process.c (read_process_output, send_process): Don't pass it.
16772 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16774 Fix previous change: the library cache is defined in w32.c.
16775 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16776 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16778 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16780 Implement dynamic loading of GnuTLS on Windows.
16782 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16783 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16784 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16787 * gnutls.c (Qgnutls_dll): Define.
16788 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
16789 (gnutls_*): Declare function pointers.

16793 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16794 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
16795 (emacs_gnutls_write, emacs_gnutls_read)
16796 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
16797 (Fgnutls_available_p): New function.
16798 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

16810 * w32.c (QCloaded_from, Vlibrary_cache): Define.
16811 (w32_delayed_load): Move from image.c. When loading a library, record
16812 its filename in the :loaded-from property of the library id.

16818 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16819 instead of gnutls_record_check_pending.
16821 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16823 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16825 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16826 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16829 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16831 * xterm.c (x_set_frame_alpha): Do not set property on anything

16855 (wait_for_termination, interruptible_wait_for_termination):
16856 Move after wait_for_termination_1.
16858 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
16860 * sysdep.c (interruptible_wait_for_termination): New function
16861 which is like wait_for_termination, but allows keyboard
16864 * callproc.c (Fcall_process): Add (:file "file") as an option for
16866 (Fcall_process_region): Ditto.
16868 2011-04-30 Eli Zaretskii <eliz@gnu.org>
16870 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
16871 rather than `XVECTOR (FOO)->size'.
16873 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16874 inttypes.h, as a gnulib replacement is used if it not available in
16877 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16879 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16880 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16881 of MOST_POSITIVE_FIXNUM. (Bug#8528)
16883 * coding.c (coding_alloc_by_realloc): Error out if destination
16884 will grow beyond MOST_POSITIVE_FIXNUM.
16885 (decode_coding_emacs_mule): Abort if there isn't enough place in

16898 * window.c (window_scroll_line_based): Use a marker instead of
16899 simple variables to record original value of point. (Bug#7952)
16901 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16902 produced by %s or %c overflows available buffer space. (Bug#8545)
16904 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16906 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

16941 Improve `doprnt' and its usage. (Bug#8545)
16942 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
16943 `format_end'. Remove support for %l as a conversion specifier.
16944 Don't use xrealloc. Improve diagnostics when the %l size modifier
16945 is used. Update the commentary.
16947 * eval.c (verror): Simplify calculation of size_t.
16949 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
16952 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
16954 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
16957 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16959 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
16960 This makes this file independent of the recent pseudovector change.
16962 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
16964 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
16966 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
16967 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
16968 Remove unused local.
16969 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
16971 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
16972 GCC 4.6.0 optimizes based on type-based alias analysis.
16973 For example, if b is of type struct buffer * and v of type struct
16974 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
16975 != &v->size, and therefore "v->size = 1; b->size = 2; return
16976 v->size;" must therefore return 1. This assumption is incorrect
16977 for Emacs, since it type-puns struct Lisp_Vector * with many other
16978 types. To fix this problem, this patch adds a new type struct
16979 vectorlike_header that documents the constraints on layout of vectors
16980 and pseudovectors, and helps optimizing compilers not get fooled
16981 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
16982 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
16983 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
16985 (XSETPVECTYPE): Rewrite in terms of new macro.
16986 (XSETPVECTYPESIZE): New macro, specifying both type and size.
16987 This is a bit clearer, and further avoids the possibility of
16988 undesirable aliasing.
16989 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
16990 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
16991 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
16992 since Lisp_Subr is a special case (no "next" field).
16993 (ASIZE): Now uses header.size rather than size.
16994 All previous uses of XVECTOR (foo)->size replaced to use this macro,
16995 to avoid the hassle of writing XVECTOR (foo)->header.size.
16996 (struct vectorlike_header): New type.
16997 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
16998 object, to help avoid aliasing.
16999 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17000 (SUBRP): Likewise, since Lisp_Subr is a special case.
17001 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17002 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17003 (struct Lisp_Hash_Table): Combine first two members into a single
17004 struct vectorlike_header member. All uses of "size" and "next" members
17005 changed to be "header.size" and "header.next".
17006 * buffer.h (struct buffer): Likewise.
17007 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17008 * frame.h (struct frame): Likewise.
17009 * process.h (struct Lisp_Process): Likewise.
17010 * termhooks.h (struct terminal): Likewise.
17011 * window.c (struct save_window_data, struct saved_window): Likewise.
17012 * window.h (struct window): Likewise.
17013 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17014 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17015 * buffer.c (init_buffer_once): Likewise.
17016 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17018 * process.c (Fformat_network_address): Use local var for size,
17021 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17023 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17024 * data.c (atof): Remove decl; no longer used or needed.
17025 (digit_to_number): Move to lread.c.
17026 (Fstring_to_number): Use new string_to_number function, to be
17027 consistent with how the Lisp reader treats infinities and NaNs.
17028 Do not assume that floating-point numbers represent EMACS_INT
17029 without losing information; this is not true on most 64-bit hosts.
17030 Avoid double-rounding errors, by insisting on integers when
17031 parsing non-base-10 numbers, as the documentation specifies.
17032 * lisp.h (string_to_number): New decl, replacing ...
17033 (isfloat_string): Remove.
17034 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17035 (read1): Do not accept +. and -. as integers; this
17036 appears to have been a coding error. Similarly, do not accept
17037 strings like +-1e0 as floating point numbers. Do not report
17038 overflow for integer overflows unless the base is not 10 which
17039 means we have no simple and reliable way to continue.
17040 Break out the floating-point parsing into a new
17041 function string_to_number, so that Fstring_to_number parses
17042 floating point numbers consistently with the Lisp reader.
17043 (digit_to_number): Move here from data.c. Make it static inline.
17044 (E_CHAR, EXP_INT): Remove, replacing with ...
17045 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17046 (string_to_number): New function, replacing isfloat_string.
17047 This function checks for valid syntax and produces the resulting
17048 Lisp float number too. Rework it so that string-to-number
17049 no longer mishandles examples like "1.0e+". Use strtoumax,
17050 so that overflow for non-base-10 numbers is reported only when
17051 there's no portable and simple way to convert to floating point.
17053 * textprop.c (set_text_properties_1): Rewrite for clarity,
17054 and to avoid GCC warning about integer overflow.
17056 * intervals.h (struct interval): Use EMACS_INT for members
17057 where EMACS_UINT might cause problems. See
17058 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17059 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17060 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17062 (offset_intervals): Tell GCC not to worry about length overflow
17063 when negating a negative length.
17065 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17066 (overrun_check_free): Likewise.
17068 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17069 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17072 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17073 (gnutls_make_error): Rename local to avoid shadowing.
17074 (gnutls_emacs_global_deinit): ifdef out; not used.
17075 (Fgnutls_boot): Use const for pointer to readonly storage.
17076 Comment out unused local. Fix pointer signedness problems.
17078 * lread.c (openp): Don't stuff size_t into an 'int'.
17079 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17080 about possible signed overflow.
17082 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17083 (GDK_KEY_g): Don't define if already defined.
17084 (xg_prepare_tooltip): Avoid pointer signedness problem.
17085 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17087 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17088 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17090 * xfns.c (Fx_window_property): Simplify a bit,
17091 to make a bit faster and to avoid GCC 4.6.0 warning.
17092 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17094 * fns.c (internal_equal): Don't assume size_t fits in int.
17096 * alloc.c (compact_small_strings): Tighten assertion a little.
17098 Replace pEd with more-general pI, and fix some printf arg casts.
17099 * lisp.h (pI): New macro, generalizing old pEd macro to other
17100 conversion specifiers. For example, use "...%"pI"d..." rather
17101 than "...%"pEd"...".
17102 (pEd): Remove. All uses replaced with similar uses of pI.
17103 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17104 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17105 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17106 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17107 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17108 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17109 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17111 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17112 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17113 * print.c (safe_debug_print, print_object): Likewise.
17114 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17116 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17117 avoiding the 0 flag, which is not portable.
17118 * process.c (Fmake_network_process): Use pI to avoid cast.
17119 * region-cache.c (pp_cache): Likewise.
17120 * xdisp.c (decode_mode_spec): Likewise.
17121 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17122 behavior on 64-bit hosts with printf arg.
17123 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17124 (x_stop_queuing_selection_requests): Likewise.
17125 (x_get_window_property): Don't truncate byte count to an 'int'
17128 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17129 here, since it parses constructs like leading '-' and spaces,
17130 which are not wanted; and it overflows with large numbers.
17131 Instead, simply match F[0-9]+, which is what is wanted anyway.
17133 * alloc.c: Remove unportable assumptions about struct layout.
17134 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17135 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17136 (allocate_vectorlike, make_pure_vector): Use the new macros,
17137 plus offsetof, to remove unportable assumptions about struct layout.
17138 These assumptions hold on all porting targets that I know of, but
17139 they are not guaranteed, they're easy to remove, and removing them
17140 makes further changes easier.
17142 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17143 This doesn't fix a bug but makes the code clearer.
17144 (string_overrun_cookie): Now const. Use initializers that
17145 don't formally overflow signed char, to avoid warnings.
17146 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17147 can cause Emacs to crash when string overrun checking is enabled.
17148 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17149 multiple of sizeof (EMACS_INT); it need not be, if
17150 alignof(EMACS_INT) < sizeof (EMACS_INT).
17151 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17153 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17160 supposed to be handshaking. (Bug#8556)
17161 Reported by Paul Eggert <eggert@cs.ucla.edu>.
17163 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
17165 * lisp.h (Qdebug): List symbol.
17166 * eval.c (Qdebug): Restore global linkage.

17168 (handle_user_signal): Break into debugger when debug-on-event
17169 matches the current signal symbol.
17171 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
17173 * alloc.c (check_sblock, check_string_bytes)
17174 (check_string_free_list): Convert to standard C.
17176 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
17178 * w32.c (emacs_gnutls_push): Fix typo.
17180 2011-04-25 Eli Zaretskii <eliz@gnu.org>
17182 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17183 "cast to pointer from integer of different size".
17185 Improve doprnt and its use in verror. (Bug#8545)
17186 * doprnt.c (doprnt): Document the set of format control sequences
17187 supported by the function. Use SAFE_ALLOCA instead of always
17190 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17191 is one byte too soon. Don't use xrealloc; instead xfree and
17194 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17196 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
17199 * gnutls.c: Renamed global_initialized to
17200 gnutls_global_initialized. Added internals for the
17201 :verify-hostname-error, :verify-error, and :verify-flags
17202 parameters of `gnutls-boot' and documented those parameters in the
17203 docstring. Start callback support.
17204 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17205 unless a fatal error occurred. Call gnutls_alert_send_appropriate
17206 on error. Return error code.
17207 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
17208 (emacs_gnutls_read): Likewise.
17209 (Fgnutls_boot): Return handshake error code.
17210 (emacs_gnutls_handle_error): New function.

17273 <char-direction-table>: Deleted.
17275 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17277 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
17278 * doprnt.c: Include limits.h.
17279 (SIZE_MAX): New macro.
17280 (doprnt): Return a size_t value. 2nd arg is now size_t.
17281 Many local variables are now size_t instead of int or unsigned.
17282 Improve overflow protection. Support `l' modifier for integer
17283 conversions. Support %l conversion. Don't assume an EMACS_INT
17284 argument for integer conversions and for %c.
17286 * lisp.h (doprnt): Restore prototype.
17288 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
17289 $(SRC)/character.h.
17291 * Makefile.in (base_obj): Add back doprnt.o.
17293 * deps.mk (doprnt.o): Add back prerequisites.
17294 (callint.o): Depend on character.h.
17296 * eval.c (internal_lisp_condition_case): Include the handler
17297 representation in the error message.
17298 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
17299 when breaking from the loop.
17301 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
17303 * callint.c (Fcall_interactively): When displaying error message
17304 about invalid control letter, pass the character's codepoint, not
17305 a pointer to its multibyte form. Improve display of the character
17306 in octal and display also its hex code.
17308 * character.c (char_string): Use %x to display the (unsigned)
17309 codepoint of an invalid character, to avoid displaying a bogus
17312 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
17313 `error', not SYMBOL_NAME itself.
17315 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
17316 character arguments to `error'.
17318 * charset.c (check_iso_charset_parameter): Fix incorrect argument
17319 to `error' in error message about FINAL_CHAR argument. Make sure
17320 FINAL_CHAR is a character, and use %c when it is passed as
17321 argument to `error'.

17385 Define only if needed.
17387 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
17388 by pacifying GCC about it. Maybe it's time to retire it?
17389 * xfaces.c (USG, __TIMEVAL__): Likewise.
17391 * dispextern.h (struct redisplay_interface): Rename param
17392 to avoid shadowing.
17393 * termhooks.h (struct terminal): Likewise.
17394 * xterm.c (xembed_send_message): Likewise.
17396 * insdel.c (make_gap_smaller): Define only if
17397 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
17399 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
17402 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
17403 so that we aren't warned about unused symbols.
17405 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
17407 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
17409 * xfns.c (x_real_positions): Mark locals as initialized.
17411 * xmenu.c (xmenu_show): Don't use uninitialized vars.

17414 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
17415 (x_dispatch_event): Declare static if USE_GTK, and
17416 define if USE_GTK || USE_X_TOOLKIT.
17417 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.

17510 * nsfont.m: Fixed bugs in ns_get_family and
17511 ns_descriptor_to_entity that were caused by using free to
17512 deallocate memory blocks that were allocated by xmalloc (via

17514 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
17515 --enable-checking=xmallocoverrun). xfree is now used to
17516 deallocate these memory blocks.

17857 * ccl.c (Vccl_program_table): Now static.
17858 (check_ccl_update): Remove; unused.
17860 * category.c (SET_CATEGORY_SET, set_category_set): Move here.
17861 * category.h: ... from here.
17862 * category.c (check_category_table, set_category_set): Now static.
17864 * casetab.c (Vascii_upcase_table, Vascii_eqv_table): Now static.
17865 * lisp.h: Remove these decls.
17867 * buffer.c (buffer_count): Remove unused var.
17869 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
17870 so that it's not optimized away.
17871 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
17872 * dispextern.h (bidi_dump_cached_states): Remove, since it's
17873 exported only to the debugger.
17875 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
17876 * atimer.h (run_all_atimers): Remove; not exported.
17878 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
17879 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
17880 was inaccessible from Lisp.
17881 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
17882 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
17884 alloc.c: Import and export fewer symbols, and remove unused items.
17885 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
17887 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
17888 it's not optimized away by whole-program optimization.
17889 (message_enable_multibyte, free_misc): Remove.
17890 (catchlist, handlerlist, mark_backtrace):
17891 Declare only if BYTE_MARK_STACK.
17892 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
17893 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
17894 (message_enable_multibyte): Remove decl.
17895 (free_misc, interval_free_list, float_block, float_block_index):
17896 (n_float_blocks, float_free_list, cons_block, cons_block_index):
17897 (cons_free_list, last_marked_index):
17899 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
17900 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
17901 (mark_backtrace): Define only if BYTE_MARK_STACK.
17902 * xdisp.c (message_enable_multibyte): Now static.
17904 Declare Lisp_Object Q* variables to be 'static' if not exported.
17905 This makes it easier for human readers (and static analyzers)
17906 to see whether these variables are used from other modules.
17907 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
17908 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
17909 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
17910 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:

17912 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
17913 * xmenu.c, xselect.c:
17914 Declare Q* vars static if they are not used in other modules.
17915 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
17916 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
17917 Remove decls of unexported vars.
17918 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
17920 * lisp.h (DEFINE_FUNC): Make sname 'static'.
17922 Make Emacs functions such as Fatom 'static' by default.
17923 This makes it easier for human readers (and static analyzers)
17924 to see whether these functions can be called from other modules.
17925 DEFUN now defines a static function. To make the function external
17926 so that it can be used in other C modules, use the new macro DEFUE.
17927 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
17928 (Finit_image_library):
17929 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
17930 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
17931 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
17932 Remove decls, since these functions are now static.
17933 (Funintern, Fget_internal_run_time): New decls, since these functions
17934 were already external.
17936 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
17937 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

17943 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
17944 Mark functions with DEFUE instead of DEFUN,
17945 if they are used in other modules.
17946 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
17947 decls for now-static functions.
17948 * buffer.h (Fdelete_overlay): Remove decl.
17949 * callproc.c (Fgetenv_internal): Mark as internal.
17950 * composite.c (Fremove_list_of_text_properties): Remove decl.

17954 * doc.c (Fdocumntation_property): New forward static decl.
17955 * eval.c (Ffetch_bytecode): New forward static decl.
17956 (Funintern): Remove extern decl; now in .h file where it belongs.
17957 * fileio.c (Fmake_symbolic_link): New forward static decl.
17958 * image.c (Finit_image_library): New forward static decl.
17959 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
17960 * intervals.h (Fprevious_property_change):
17961 (Fremove_list_of_text_properties): Remove decls.
17962 * keyboard.c (Fthis_command_keys): Remove decl.
17963 (Fcommand_execute): New forward static decl.
17964 * keymap.c (Flookup_key): New forward static decl.
17965 (Fcopy_keymap): Now static.
17966 * keymap.h (Flookup_key): Remove decl.
17967 * process.c (Fget_process): New forward static decl.
17968 (Fprocess_datagram_address): Mark as internal.

17979 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
17981 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
17984 2011-04-13 Eli Zaretskii <eliz@gnu.org>
17986 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
17987 when at ZV. (Bug#8487)
17989 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
17991 * charset.c (Fclear_charset_maps): Use xfree instead of free.

17994 * sound.c (sound_cleanup, alsa_close): Likewise.
17995 * termcap.c (tgetent): Likewise.

17997 * xsettings.c (read_and_apply_settings): Likewise.
17999 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18000 (overrun_check_free): Protoize.
18002 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18004 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18005 since callers should never pass a negative size.
18006 Change the signature to match that of plain 'read' and 'write'; see
18007 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18008 * lisp.h: Update prototypes of emacs_write and emacs_read.
18010 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18012 * xdisp.c (redisplay_window): Don't try to determine the character
18013 position of the scroll margin if the window start point w->startp
18014 is outside the buffer's accessible region. (Bug#8468)
18016 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18018 Fix write-region and its subroutines for buffers > 2GB.
18019 * fileio.c (a_write, e_write): Modify declaration of arguments and
18020 local variables to support buffers larger than 2GB.
18021 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18023 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18024 argument, local variables, and return value.
18026 * lisp.h: Update prototypes of emacs_write and emacs_read.
18028 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18030 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18032 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18034 Fix more problems found by GCC 4.6.0's static checks.
18036 * xdisp.c (vmessage): Use a better test for character truncation.
18038 * charset.c (load_charset_map): <, not <=, for optimization,
18039 and to avoid potential problems with integer overflow.
18040 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18041 * casetab.c (set_identity, shuffle): Likewise.
18042 * editfns.c (Fformat): Likewise.
18043 * syntax.c (skip_chars): Likewise.
18045 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18046 This also lets GCC 4.6.0 generate slightly better loop code.
18048 * callint.c (Fcall_interactively): <, not <=, for optimization.
18049 (Fcall_interactively): Count the number of arguments produced,
18050 not the number of arguments given. This is simpler and lets GCC
18051 4.6.0 generate slightly better code.
18053 * ftfont.c: Distingish more carefully between FcChar8 and char.
18054 The previous code passed unsigned char * to a functions like
18055 strlen and xstrcasecmp that expect char *, which does not
18056 conform to the C standard.
18057 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18058 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18059 char * when the C standard requires it.
18061 * keyboard.c (read_char): Remove unused var.
18063 * eval.c: Port to Windows vsnprintf (Bug#8435).
18064 Include <limits.h>.
18065 (SIZE_MAX): Define if the headers do not.
18066 (verror): Do not give up if vsnprintf returns a negative count.
18067 Instead, grow the buffer. This ports to Windows vsnprintf, which
18068 does not conform to C99. Problem reported by Eli Zaretskii.
18069 Also, simplify the allocation scheme, by avoiding the need for
18070 calling realloc, and removing the ALLOCATED variable.
18072 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18074 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18075 But keep the doprint source code for now, as we might revamp it
18076 and use it again (Bug#8435).
18077 * lisp.h (doprnt): Remove.
18078 * Makefile.in (base_obj): Remove doprnt.o.
18079 * deps.mk (doprnt.o): Remove.
18081 error: Print 32- and 64-bit integers portably (Bug#8435).
18082 Without this change, on typical 64-bit hosts error ("...%d...", N)
18083 was used to print both 32- and 64-bit integers N, which relied on
18084 undefined behavior.
18085 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18086 * lisp.h (error, verror): Mark as printf-like functions.
18087 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18088 Report overflow in size calculations when allocating printf buffer.
18089 Do not truncate output string at its first null byte.
18090 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18091 Truncate the output at a character boundary, since vsnprintf does not
18093 * charset.c (check_iso_charset_parameter): Convert internal
18094 character to string before calling 'error', since %c now has the
18096 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18097 overflow when computing char to be passed to 'error'. Do not
18098 pass Lisp_Object to 'error'; pass the integer instead.
18099 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18100 formatted with plain %d.
18102 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18104 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18106 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18108 * xterm.c (x_catch_errors): Remove duplicate declaration.
18110 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18112 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18114 2011-04-10 Jim Meyering <meyering@redhat.com>
18116 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18117 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18118 return ssize_t not "int", and use size_t as the buffer length.
18119 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18120 * gnutls.h: Update declarations.
18121 * process.c (read_process_output): Use ssize_t, to match.
18122 (send_process): Likewise.
18124 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18126 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18128 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18130 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18131 Use unsigned char, to match FcChar8 type definition.
18133 * xterm.c (handle_one_xevent):
18134 * xmenu.c (create_and_show_popup_menu):
18135 * xselect.c (x_decline_selection_request)
18136 (x_reply_selection_request): Avoid type-punned deref of X events.
18138 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18140 Fix some uses of `int' instead of EMACS_INT.
18141 * search.c (string_match_1, fast_string_match)
18142 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18143 (scan_buffer, find_next_newline_no_quit)
18144 (find_before_next_newline, search_command, Freplace_match)
18145 (Fmatch_data): Make some `int' variables be EMACS_INT.
18147 * xdisp.c (display_count_lines): 3rd argument and return value now
18148 EMACS_INT. All callers changed.
18149 (pint2hrstr): Last argument is now EMACS_INT.
18151 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18152 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18153 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
18154 (decode_coding_utf_16, decode_coding_emacs_mule)
18155 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
18156 (decode_coding_ccl, decode_coding_charset)
18157 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
18158 (decode_coding_iso_2022, decode_coding_emacs_mule)
18159 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
18160 <char_offset, last_offset>: Declare EMACS_INT.

18164 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18165 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18167 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18168 (encode_invocation_designation): Last argument P_NCHARS is now
18170 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18171 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18173 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18176 * ccl.c (Fccl_execute_on_string): Declare some variables
18179 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18181 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18183 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18185 * process.c (Fformat_network_address): Doc fix.
18187 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18189 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18191 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18193 * keyboard.c (read_char): Call Lisp function help-form-show,
18194 instead of using internal_with_output_to_temp_buffer.
18195 (Qhelp_form_show): New var.
18196 (syms_of_keyboard): Use DEFSYM macro.
18198 * print.c (internal_with_output_to_temp_buffer): Function deleted.

18205 (list_processes_1): Delete.
18207 2011-04-06 Eli Zaretskii <eliz@gnu.org>
18209 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18211 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18213 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18215 Fix more problems found by GCC 4.6.0's static checks.
18217 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
18219 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18221 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18223 * xdisp.c (vmessage): Mark as a printf-like function.
18225 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
18227 * sound.c (sound_warning): Don't crash if arg contains a printf format.
18229 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
18230 printf-like functions.
18231 (tiff_load): Add casts to remove these marks before passing them
18232 to system-supplied API.
18234 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18236 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18237 This avoids several warnings with gcc -Wstrict-overflow.
18238 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18239 directly, rather than having caller test rule sign. This avoids
18240 some unnecessary tests.
18241 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18242 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18243 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18245 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18246 (xfont_open): Avoid unnecessary tests.
18248 * composite.c (composition_gstring_put_cache): Use unsigned integer.

18257 by using the new macro.
18259 * textprop.c (set_text_properties_1): Change while to do-while,
18260 since the condition is always true at first.
18262 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18263 (interval_deletion_adjustment): Return unsigned value.
18266 * process.c (list_processes_1, create_pty, read_process_output):
18267 (exec_sentinel): Remove vars that were set but not used.
18268 (create_pty): Remove unnecessary "volatile"s.

18295 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18296 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18297 can always succeed if overflow has undefined behavior.

18300 (wordify): Omit three unnecessary tests.
18302 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18303 All callers changed. This avoids the need for an unused var.
18305 * casefiddle.c (casify_region): Remove var that is set but not used.
18307 * dired.c (file_name_completion): Remove var that is set but not used.
18309 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18311 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18312 (Finsert_file_contents): Remove unnecessary code checking fd.
18314 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18315 Check for integer overflow on size calculations.
18317 * buffer.c (Fprevious_overlay_change): Remove var that is set
18320 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18321 Remove vars that are set but not used.
18322 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18323 (timer_check_2): Mark vars as initialized.
18325 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18327 * image.c (lookup_image): Remove var that is set but not used.
18328 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18330 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18331 that are set but not used.
18333 * xfns.c (make_invisible_cursor): Don't return garbage
18334 if XCreateBitmapFromData fails (Bug#8410).
18336 * xselect.c (x_get_local_selection, x_handle_property_notify):
18337 Remove vars that are set but not used.
18339 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18340 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
18342 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
18343 Remove var that is set but not used.
18344 (scroll_bar_windows_size): Now size_t, not int.
18345 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
18346 Check for overflow.
18348 * xfaces.c (realize_named_face): Remove vars that are set but not used.
18349 (map_tty_color) [!defined MSDOS]: Likewise.
18351 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18353 * coding.c: Remove vars that are set but not used.
18354 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18355 All callers changed.
18356 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
18357 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18358 (decode_coding_charset): Remove vars that are set but not used.
18360 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18361 that is set but not used.
18363 * print.c (print_object): Remove var that is set but not used.
18365 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18366 The gnulib version avoids calling malloc in the usual case,
18367 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18368 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18369 * filelock.c (current_lock_owner): Likewise.
18370 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18371 * sysdep.c: Include allocator.h, careadlinkat.h.
18372 (emacs_no_realloc_allocator): New static constant.
18373 (emacs_readlink): New function.
18374 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18375 ../lib/careadlinkat.h.
18377 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18379 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18380 first non-nil return value).

18394 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18395 and thereabouts. All callers changed.
18396 (get_per_char_metric): Remove parameter `f', unused since
18397 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
18399 2011-04-02 Jim Meyering <meyering@redhat.com>
18401 do not dereference NULL upon failed strdup
18402 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18403 (ns_get_family): Likewise.
18405 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18407 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
18409 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
18411 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
18414 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
18416 Add lexical binding.
18418 * window.c (Ftemp_output_buffer_show): New fun.
18419 (Fsave_window_excursion):
18420 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
18422 * lread.c (lisp_file_lexically_bound_p): New function.
18423 (Fload): Bind Qlexical_binding.
18424 (readevalloop): Remove `evalfun' arg.
18425 Bind Qinternal_interpreter_environment.
18426 (Feval_buffer): Bind Qlexical_binding.
18427 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
18429 (syms_of_lread): Declare `lexical-binding'.
18431 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
18433 * keyboard.c (eval_dyn): New fun.
18434 (menu_item_eval_property): Use it.
18436 * image.c (parse_image_spec): Use Ffunctionp.
18438 * fns.c (concat, mapcar1): Accept byte-code-functions.
18440 * eval.c (Fsetq): Handle lexical vars.
18441 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18442 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18443 (FletX, Flet): Obey lexical binding.
18444 (Fcommandp): Handle closures.
18445 (Feval): New `lexical' arg.
18446 (eval_sub): New function extracted from Feval. Use it almost
18447 everywhere where Feval was used. Look up vars in lexical env.
18449 (Ffunctionp): Move from subr.el.
18450 (Ffuncall): Handle closures.
18451 (apply_lambda): Remove `eval_flags'.
18452 (funcall_lambda): Handle closures and new byte-code-functions.
18453 (Fspecial_variable_p): New function.
18454 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18455 but without exporting it to Lisp.
18457 * doc.c (Fdocumentation, store_function_docstring):
18458 * data.c (Finteractive_form): Handle closures.
18460 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18463 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18465 (exec_byte_code): New function extracted from Fbyte_code to handle new
18466 calling convention for byte-code-functions. Add new byte-codes.
18468 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
18470 * alloc.c (Fmake_symbol): Init new `declared_special' field.
18472 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18474 * xdisp.c (redisplay_internal): Fix prototype.
18476 2011-03-31 Eli Zaretskii <eliz@gnu.org>
18478 * xdisp.c (SCROLL_LIMIT): New macro.
18479 (try_scrolling): Use it when setting scroll_limit.
18480 Limit scrolling to 100 screen lines.
18481 (redisplay_window): Even when falling back on "recentering",
18482 position point in the window according to scroll-conservatively,
18483 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18485 (try_scrolling): When point is above the window, allow searching
18486 as far as scroll_max, or one screenful, to compute vertical
18487 distance from PT to the scroll margin position. This prevents
18488 try_scrolling from unnecessarily failing when
18489 scroll-conservatively is set to a value slightly larger than the
18490 window height. Clean up the case of PT below the margin at bottom
18491 of window: scroll_max can no longer be INT_MAX. When aggressive
18492 scrolling is in use, don't let point enter the opposite scroll
18493 margin as result of the scroll.
18494 (syms_of_xdisp) <scroll-conservatively>: Document the
18495 threshold of 100 lines for never-recentering scrolling.
18497 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

18502 (message_log_check_duplicate): Remove parameters `prev_bol' and
18503 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18504 (redisplay_internal): Remove parameter `preserve_echo_area',
18505 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18507 * indent.c (Fvertical_motion):
18508 * window.c (window_scroll_pixel_based, Frecenter):
18509 Don't pass `need_y_p' to `move_it_by_lines'.
18511 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18513 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18514 steal a few bits to be more compact.
18515 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18516 Remove unneeded casts.
18518 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18520 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18522 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18523 binding" message (bug#7967).
18525 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18527 Fix more problems found by GCC 4.6.0's static checks.
18529 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18530 Remove unused local var.
18532 * editfns.c (Fmessage_box): Remove unused local var.
18534 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18535 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18536 Omit unused local vars.
18537 * window.c (shrink_windows): Omit unused local var.
18538 * menu.c (digest_single_submenu): Omit unused local var.
18539 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18540 Omit unused local var.
18542 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18543 Don't assume string length fits in int.
18544 (keyremap_step, read_key_sequence): Use size_t for sizes.
18545 (read_key_sequence): Don't check last_real_key_start redundantly.
18547 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18548 instead of alloca (Bug#8344).
18550 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18551 (Fbacktrace_frame): Don't assume nframes fits in int.
18553 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

18558 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18560 * cm.c (calccost): Turn while-do into do-while, for clarity.
18562 * keyboard.c (syms_of_keyboard): Use the same style as later
18563 in this function when indexing through an array. This also
18564 works around GCC bug 48267.
18566 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18568 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18570 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18571 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18573 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18574 This avoids undefined behavior on integer overflow, and is a bit
18575 more convenient anyway since it is compared to a size_t variable.
18577 Variadic C functions now count arguments with size_t, not int.
18578 This avoids an unnecessary limitation on 64-bit machines, which
18579 caused (substring ...) to crash on large vectors (Bug#8344).

18589 * fns.c (concat): Likewise.
18590 * frame.c (x_set_frame_parameters): Likewise.
18591 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18592 0 if not found, not -1. All callers changed.
18594 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18595 (stack_copy_size): Now size_t, not int.
18596 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
18598 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18600 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
18601 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18602 All callers changed.
18604 * lisp.h (multibyte_char_to_unibyte):
18605 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',

18617 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18618 don't set the hook to nil, but remove the offending function instead.
18619 (Qcommand_hook_internal): Remove, unused.
18620 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18621 Vcommand_hook_internal.

18624 (funcall_nil, funcall_not): New functions.
18625 (run_hook_with_args): Call each function through a `funcall' argument.

18639 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18640 All callers changed.
18642 * w32.c (_wsa_errlist): Use braces for struct initializers.
18644 * xdisp.c (string_buffer_position_lim): Remove parameter `w',

18760 Remove unused variable `width'.
18762 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
18764 * w32term.c (x_set_glyph_string_clipping):
18765 Don't pass uninitialized region to CombineRgn.
18767 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
18769 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

18789 2011-03-23 Julien Danjou <julien@danjou.info>
18791 * term.c (Fsuspend_tty, Fresume_tty):
18792 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
18793 * window.c (temp_output_buffer_show):
18794 * insdel.c (signal_before_change):
18795 * frame.c (Fhandle_switch_frame):
18796 * fileio.c (Fdo_auto_save):

18799 * cmds.c (internal_self_insert):
18800 * callint.c (Fcall_interactively):
18801 * buffer.c (Fkill_all_local_variables):
18802 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18804 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18805 unconditionally since it does the check itself.
18807 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18809 Fix more problems found by GCC 4.5.2's static checks.
18811 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18812 the first time through the loop, since we know p0 < p1 then.
18813 This also avoids a gcc -Wstrict-overflow warning.
18815 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18816 leading to a memory leak, possible in functions like
18817 load_charset_map_from_file that can allocate an unbounded number
18818 of objects (Bug#8318).
18820 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18821 that could (at least in theory) be that large.
18823 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18824 This is less likely to overflow, and avoids undefined behavior if
18825 overflow does occur. All callers changed. Use strtoul to scan
18826 for the unsigned long integer.
18827 (pint2hrstr): Simplify and tune code slightly.
18828 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
18830 * scroll.c (do_scrolling): Work around GCC bug 48228.
18831 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
18833 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
18834 This also avoids a warning with gcc -Wstrict-overflow.
18835 (validate_x_resource_name): Simplify count usage.
18836 This also avoids a warning with gcc -Wstrict-overflow.
18838 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18841 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18843 * process.c (Fmake_network_process): Use socklen_t, not int,
18844 where POSIX says socklen_t is required in portable programs.
18845 This fixes a porting bug on hosts like 64-bit HP-UX, where
18846 socklen_t is wider than int (Bug#8277).
18847 (Fmake_network_process, server_accept_connection):
18848 (wait_reading_process_output, read_process_output):
18851 * process.c: Rename or move locals to avoid shadowing.
18852 (list_processes_1, Fmake_network_process):
18853 (read_process_output_error_handler, exec_sentinel_error_handler):
18854 Rename or move locals.
18855 (Fmake_network_process): Define label "retry_connect" only if needed.
18856 (Fnetwork_interface_info): Fix pointer signedness.

18861 Make tparam.h and terminfo.c consistent.
18862 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18863 Include tparam.h instead, since it declares them.
18864 * cm.h (PC): Remove extern decl; tparam.h now does this.
18865 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18866 * terminfo.c: Include tparam.h, to check interfaces.
18867 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18868 (tparam): Adjust signature to match interface in tparam.h;
18869 this removes some undefined behavior. Check that outstring and len
18870 are zero, which they always are with Emacs.
18871 * tparam.h (PC, BC, UP): New extern decls.
18873 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18874 (xftfont_open): Rename locals to avoid shadowing.
18876 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
18877 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
18878 (OTF_TAG_SYM): Omit macro if not needed.
18879 (ftfont_list): Remove unused local.
18880 (get_adstyle_property, ftfont_pattern_entity):
18881 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):

18886 * xml.c (make_dom): Now static.
18888 * composite.c (composition_compute_stop_pos): Rename local to
18890 (composition_reseat_it): Remove unused locals.
18891 (find_automatic_composition, composition_adjust_point): Likewise.
18892 (composition_update_it): Mark var as initialized.
18893 (find_automatic_composition): Mark vars as initialized,
18894 with a FIXME (Bug#8290).
18896 character.h: Rename locals to avoid shadowing.
18897 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
18898 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18899 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18900 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18901 to avoid shadowing.
18903 * textprop.c (property_change_between_p): Remove; unused.
18905 * intervals.c (interval_start_pos): Now static.
18907 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

18910 Rename locals to avoid shadowing.
18912 * sound.c (wav_play, au_play, Fplay_sound_internal):
18913 Fix pointer signedness.
18914 (alsa_choose_format): Remove unused local var.
18915 (wav_play): Initialize a variable to 0, to prevent undefined
18916 behavior (Bug#8278).
18918 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18920 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18922 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18923 clobbering (Bug#8298).
18924 * sysdep.c (sys_subshell): Likewise.
18925 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18927 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18928 This should get cleaned up, so that child_setup has the
18929 same signature on all platforms.
18931 * callproc.c (call_process_cleanup): Now static.
18932 (relocate_fd): Rename locals to avoid shadowing.
18934 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18936 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18937 not to be necessary, and produces flickering.
18939 2011-03-20 Glenn Morris <rgm@gnu.org>
18941 * config.in: Remove file.
18943 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
18945 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
18946 are now in src/globals.h.
18947 (syms_of_minibuf): Remove spurious & from previous change.
18949 2011-03-20 Leo Liu <sdl.web@gmail.com>
18951 * minibuf.c (completing-read-function): New variable.
18952 (completing-read-default): Rename from completing-read.
18953 (completing-read): Call completing-read-function.
18955 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
18957 * xfaces.c (Fx_load_color_file):
18958 Read color file from absolute filename (bug#8250).
18960 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
18962 * makefile.w32-in: Update dependencies.
18964 2011-03-17 Eli Zaretskii <eliz@gnu.org>
18966 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
18968 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>

18972 * process.c (make_serial_process_unwind, send_process_trap):
18973 (sigchld_handler): Now static.
18975 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
18976 That way, the code declares only the vars that it needs.
18977 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
18978 * s/cygwin.h (PTY_ITERATION): Likewise.
18979 * s/darwin.h (PTY_ITERATION): Likewise.

18983 * process.c (allocate_pty): Don't declare stb unless it's needed.
18985 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
18986 (CONSTANTLIM): Remove; unused.
18987 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
18988 Define only if needed.
18990 * unexelf.c (unexec): Name an expression,
18991 to avoid gcc -Wbad-function-cast warning.
18992 Use a different way to cause a compilation error if anyone uses
18993 n rather than nn, a way that does not involve shadowing.
18994 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
18996 * deps.mk (unexalpha.o): Remove; unused.
18998 New file unexec.h, the (simple) interface for unexec (Bug#8267).
18999 * unexec.h: New file.
19000 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
19001 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
19002 Depend on unexec.h.
19003 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
19004 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
19005 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
19006 Change as necessary to match prototype in unexec.h.
19008 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
19010 (back_comment, skip_chars): Mark vars as initialized.
19012 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

19024 instead of using an uninitialized var.
19025 (font_sort_entities): Mark var as initialized.
19027 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
19029 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

19042 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
19044 * alloc.c (mark_backtrace): Move decl from here ...

19053 * callint.c (quotify_arg, quotify_args): Now static.
19054 (Fcall_interactively): Rename locals to avoid shadowing.
19055 Use const pointer when appropriate.

19059 * process.c (get_operating_system_release): Move decl to lisp.h.
19060 * xrdb.c (get_system_name): Likewise.
19061 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
19062 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
19063 some of which prompt warnings from gcc -Wbad-function-cast.
19064 (Fformat_time_string, Fencode_time, Finsert_char):
19065 (Ftranslate_region_internal, Fformat):
19066 Rename or remove local vars to avoid shadowing.
19067 (Ftranslate_region_internal): Mark var as initialized.
19069 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
19072 * lisp.h (eassert): Check that the argument compiles, even if
19073 ENABLE_CHECKING is not defined.
19075 * data.c (Findirect_variable): Name an expression, to avoid
19076 gcc -Wbad-function-cast warning.
19077 (default_value, arithcompare, arith_driver, arith_error): Now static.

19084 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
19085 Rename locals to avoid shadowing.
19086 (mark_stack): Move local variables into the #ifdef region where
19088 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
19089 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
19091 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
19092 (GC_STRING_CHARS): Remove; not used.
19093 (Fmemory_limit): Cast sbrk's returned value to char *.
19095 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
19096 avoids undefined behavior in theory.
19098 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
19100 Use functions, not macros, for up- and down-casing (Bug#8254).
19101 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19102 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
19103 to use the following functions instead of these macros.
19104 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
19105 EMACS_INT, since callers assume the returned value fits in int.
19106 (upcase1): Likewise, for UPCASE_TABLE.
19107 (uppercasep, lowercasep, upcase): New static inline functions.
19108 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
19109 the race-condition problem in the old DOWNCASE.
19111 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
19112 Rename locals to avoid shadowing.
19113 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
19114 (regex_compile, re_search_2, re_match_2_internal):
19115 Remove unused local vars.
19116 (FREE_VAR): Rewrite so as not to use empty "else",
19117 which gcc can warn about.
19118 (regex_compile, re_match_2_internal): Mark locals as initialized.
19119 (RETALLOC_IF): Define only if needed.
19120 (WORDCHAR_P): Likewise. This one is never needed, but is used
19121 only in a comment talking about a compiler bug, so put inside
19122 the #if 0 of that comment.
19123 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19124 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
19127 * search.c (boyer_moore): Rename locals to avoid shadowing.
19128 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
19129 (PREV_CHAR_BOUNDARY): Likewise.
19131 * search.c (simple_search): Remove unused var.
19133 * dired.c (compile_pattern): Move decl from here ...

19139 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
19141 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
19142 Rename locals to avoid shadowing.
19143 (Fvertical_motion): Mark locals as initialized.
19145 * casefiddle.c (casify_object, casify_region): Now static.
19146 (casify_region): Mark local as initialized.
19148 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
19150 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
19151 New macros, so that the caller can use some names other than
19152 gcpro1, gcpro2, etc.
19153 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19155 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19156 argument, for consistency with GCPRO2_VAR, etc: it is now the
19157 prefix of the variable, not the variable itself. All uses
19159 * dired.c (directory_files_internal, file_name_completion):
19160 Rename locals to avoid shadowing.
19162 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19163 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19164 dired.c's scmp function, had undefined behavior.
19165 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19166 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19167 * buffer.h: ... to here, because these macros use current_buffer,
19168 and the new implementation with inline functions needs to have
19169 current_buffer in scope now, rather than later when the macros
19171 (downcase, upcase1): New static inline functions.
19172 (DOWNCASE, UPCASE1): Reimplement using these functions.
19173 This avoids undefined behavior in expressions like
19174 DOWNCASE (x) == DOWNCASE (y), which previously suffered
