3 * w32.c (sys_open): Zero out the flags for the new file descriptor.
4 (sys_close): Zero out the flags for the file descriptor before
5 closing it. (Bug#13546)
7 2013-01-26 Eli Zaretskii <eliz@gnu.org>
9 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
10 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
11 CharNextExA and CharPrevExA to iterate over file names encoded in
14 2013-01-25 Eli Zaretskii <eliz@gnu.org>
16 * w32.c (w32_get_long_filename, init_environment, readlink):
17 Support file names encoded in DBCS codepages.
18 (readlink): Use the current file-name-coding-system, not the ANSI
19 codepage, to decode and handle targets of symlinks.
21 2013-01-23 Eli Zaretskii <eliz@gnu.org>
23 * w32.c (max_filename_mbslen): New function.
24 (normalize_filename, readdir): Use it to detect locales where ANSI
25 encoding of file names uses a double-byte character set (DBCS).
26 If a DBCS encoding is used, advance by characters using
27 CharNextExA, instead of incrementing a 'char *' pointer. Use
28 _mbslwr instead of _strlwr. (Bug#13515)
30 2013-01-22 Eli Zaretskii <eliz@gnu.org>
32 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
33 request of memory reservation to 1.7GB. (Bug#13065)
35 2013-01-20 Andreas Schwab <schwab@linux-m68k.org>
37 * coding.c (detect_coding_iso_2022): Move back mis-reordered code

48 (ns_glyph_metrics): Add LCD_SMOOTHING_MARGIN to bearings to fix
49 Bug#11484 with LCD smoothing on.
51 2013-01-11 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> (tiny change)
53 * gtkutil.c (xg_initialize): Backport from trunk.
54 Add ifdef HAVE_FREETYPE around x_last_font_name (Bug#13403).
56 2013-01-11 Paul Eggert <eggert@cs.ucla.edu>
58 Backport typo fix from trunk, for AIX (Bug#13408).
59 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
60 This follows up on the 2012-09-29 patch that removed indirection
61 for the 'function' field. Reported by Sergey Vinokurov in
62 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
64 Fix SIGDANGER handlers, for AIX (Bug#13408).
65 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
66 Move handlers here from emacs.c; they were out of place.
68 2013-01-05 Eli Zaretskii <eliz@gnu.org>
70 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
71 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
72 digits for buffer positions, before misalignment starts. Display
73 "0" for integer "object" field.
74 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
75 Display the newline glyph more unambiguously.
77 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
79 * nsterm.m (ns_draw_underwave):
80 * w32term.c (w32_draw_underwave):
81 * xterm.c (x_draw_underwave): Make underwave look more triangular
82 and also degrade gracefully for small fonts. (Bug#13000)
84 * nsterm.m (ns_draw_text_decoration):
85 * w32term.c (x_draw_glyph_string):
86 * xterm.c (x_draw_glyph_string): Don't use previous underline
87 thickness and position if previous underline type is underwave.
89 2012-12-31 Glenn Morris <rgm@gnu.org>
91 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
93 2012-12-29 Andreas Schwab <schwab@linux-m68k.org>
95 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
96 (LIBS_GNUSTEP): Define.
97 (LIBES): Add $(LIBS_GNUSTEP).
98 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
100 2012-12-27 Eli Zaretskii <eliz@gnu.org>
102 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
103 continuation glyph on a TTY with an indication of an empty line.
106 2012-12-27 Glenn Morris <rgm@gnu.org>
108 * cygw32.c (Fcygwin_convert_file_name_to_windows)
109 (Fcygwin_convert_file_name_from_windows): Doc fixes.
111 2012-12-24 Eli Zaretskii <eliz@gnu.org>
113 * fileio.c (file_name_as_directory, directory_file_name): Accept
114 an additional argument MULTIBYTE to indicate whether the input C
115 came from a multibyte or a unibyte Lisp string; all callers
116 adjusted. Don't assume the input string is always multibyte.
118 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
119 don't ENCODE_FILE them, and return a unibyte string if the input
121 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
122 don't assume the input strings will always be multibyte. If the
123 input strings are multibyte, decode strings obtained from C
126 2012-12-22 Martin Rudalics <rudalics@gmx.at>
128 * window.c (Fselect_window): Reword doc-string (Bug#13248).
130 2012-12-21 Eli Zaretskii <eliz@gnu.org>
132 * fileio.c (Finsert_file_contents): Doc fix.
134 * w32proc.c (new_child, delete_child, find_child_pid): For a
135 subprocess, consider its slot being in use as long as its process
136 handle (procinfo.hProcess) is not NULL. This avoids reusing the
137 slot when a new process is started immediately after killing
138 another one, without waiting enough time for the first process to
139 be reaped and resources allocated for it be orderly freed.
141 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
143 2012-12-21 Chong Yidong <cyd@gnu.org>

151 2012-12-14 Eli Zaretskii <eliz@gnu.org>
153 * w32.c (get_name_and_id): Always pass NULL as the first argument
154 of lookup_account_sid. Avoids crashes with UNC file names that
155 refer to DFS domains, not to specific machine names. (Bug#12621)
156 Remove now unused argument FNAME; all callers changed.
157 (get_file_owner_and_group): Remove now unused argument FNAME; all
160 2012-12-11 Eli Zaretskii <eliz@gnu.org>
162 * search.c (search_buffer): Check the inverse translations of each
163 character in pattern when the buffer being searched is unibyte.
166 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>
168 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
169 files, fixing a regression from 24.2.

172 2012-12-08 Jan Djärv <jan.h.d@swipnet.se>
174 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
176 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
178 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
179 DWORD_PTR, for compatibility with 64-bit builds.
181 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
182 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
183 (system_process_attributes): Use SIZE_T rather than DWORD, for
184 compatibility with 64-bit builds.
186 2012-12-08 Christopher Schmidt <christopher@ch.ristopher.com>

190 2012-12-07 Eli Zaretskii <eliz@gnu.org>
192 * indent.c (Fvertical_motion): If a display string will be
193 displayed on the left or the right margin, don't consider it as a
194 factor in cursor positioning. (Bug#13108)
196 2012-12-07 Martin Rudalics <rudalics@gmx.at>
198 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
200 2012-12-05 Eli Zaretskii <eliz@gnu.org>
202 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
203 fails, signal an error instead of continuing with an empty
205 Encode expanded temp file pattern before passing it to mkstemp or
208 2012-12-04 Eli Zaretskii <eliz@gnu.org>
210 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
211 Encode the file name before passing it to dostounix_filename, in
212 case it will downcase it (under w32-downcase-file-names).
215 2012-12-01 Chong Yidong <cyd@gnu.org>
217 * fileio.c (Vauto_save_list_file_name): Doc fix.
219 2012-11-30 Fabrice Popineau <fabrice.popineau@gmail.com>
221 * w32fns.c: Remove prototype of atof.
222 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
224 (file_dialog_callback): Declared UINT_PTR.
226 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
229 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
230 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
233 2012-11-27 Glenn Morris <rgm@gnu.org>
235 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
237 2012-11-26 Eli Zaretskii <eliz@gnu.org>
239 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
242 2012-11-24 Paul Eggert <eggert@cs.ucla.edu>
244 Revert recent change for Bug#8855.
245 As reported by Harald Hanche-Olsen in
246 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00445.html>
247 the change introduces a further bug, of creating lots of zombie
248 processes in some cases. Further work is needed to come up with a
249 better fix for Bug#8855.
251 2012-11-24 Eli Zaretskii <eliz@gnu.org>
253 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
254 highlighting on the frame was cleared. Prevents assertion
255 violations when repeatedly clicking on the "Top" link of the
256 "bread-crumbs" in Info buffers.
258 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
259 Eli Zaretskii <eliz@gnu.org>
261 Fix a race condition with glib (Bug#8855).
262 The symptom is a diagnostic "GLib-WARNING **: In call to
263 g_spawn_sync(), exit status of a child process was requested but
264 SIGCHLD action was set to SIG_IGN and ECHILD was received by
265 waitpid(), so exit status can't be returned." The diagnostic
266 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
267 The real bug is a race condition between Emacs and glib: Emacs
268 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
269 so that glib can't find it. Work around the bug by invoking
270 waitpid only on subprocesses that Emacs itself creates.
272 This is a backport from the trunk, consisting of:
274 * w32proc.c (create_child): Don't clip the PID of the child
275 process to fit into an Emacs integer, as this is no longer a
277 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
278 reaping only the process specified by PID argument, if that is
279 positive. Use PID instead of dead_child to know which process to
280 reap. Wait for the child to die only if WNOHANG is not in
282 (sys_select): Don't set dead_child.
284 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
285 as it is no longer needed.
287 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
289 (create_process, record_child_status_change): Don't use special
290 value -1 in pid field, as the caller now must know the pid rather
291 than having the callee infer it. The inference was sometimes
292 incorrect anyway, due to another race.
293 (create_process): Set new 'alive' member if child is created.
294 (process_status_retrieved): New function.
295 (record_child_status_change): Use it.
296 Accept negative 1st argument, which means to wait for the
297 processes that Emacs already knows about. Move special-case code
298 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
299 processes that have already been waited for, by testing and
300 clearing new 'alive' member. Remove the setting of
301 record_at_most_one_child for the !WNOHANG case.
302 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
303 now does this internally.
304 (handle_child_signal): Let record_child_status_change do all
305 the work, since we do not want to reap all exited child processes,
306 only the child processes that Emacs itself created.
307 * process.h (Lisp_Process): New boolean member 'alive'.
309 2012-11-23 Eli Zaretskii <eliz@gnu.org>
311 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
312 between bpos_covered and bpos_max. This fixes cursor display when
313 several display strings follow each other.
315 * .gdbinit (pgx): If the glyph's object is a string, display the
316 pointer to string data, rather than the value of the string object
317 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
319 2012-11-21 Eli Zaretskii <eliz@gnu.org>
321 * indent.c (Fvertical_motion): If the starting position is covered
322 by a display string, return to one position before that, to avoid
323 overshooting it inside move_it_to. (Bug#12930)
325 2012-11-20 Daniel Colascione <dancol@dancol.org>
327 * w32fns.c (Fx_file_dialog):
328 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
329 cygwin_convert_file_name*.
331 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
332 Rename cygwin_convert_path* to cygwin_convert_file_name*.
334 2012-11-20 Ken Brown <kbrown@cornell.edu>
336 * emacs.c (main): Set the G_SLICE environment variable for all
337 Cygwin builds, not just GTK builds. See
338 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
340 2012-11-19 Eli Zaretskii <eliz@gnu.org>
342 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Don't mix declaration of
343 w32_note_current_window with code. (Backport from trunk.)
345 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
346 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
347 Define for the MSVC compiler.
349 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing
352 2012-11-18 Eli Zaretskii <eliz@gnu.org>
354 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
355 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
356 dostounix_filename. Prevents crashes down the road, because
357 dostounix_filename assumes it gets a unibyte string. Reported by
358 Michel de Ruiter <michel@sentient.nl>, see
359 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
361 2012-11-17 Eli Zaretskii <eliz@gnu.org>
363 * w32select.c: Include w32common.h before w32term.h, so that
364 windows.h gets included before w32term.h uses some of its
367 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
369 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
371 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
373 2012-11-17 Jan Djärv <jan.h.d@swipnet.se>
375 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
376 (ns_select): Return at once if events are held (Bug#12834).
378 2012-11-16 enami tsugutomo <tsugutomo.enami@jp.sony.com>
380 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
381 Needed following 2012-10-20 change. (Bug#12902)
383 2012-11-16 Glenn Morris <rgm@gnu.org>
385 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
387 2012-11-15 Stefan Monnier <monnier@iro.umontreal.ca>
389 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
391 2012-11-14 Eli Zaretskii <eliz@gnu.org>
393 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
394 use the same value of thread handle.
395 (start_timer_thread): If the timer thread exited (due to error),
396 clean up by closing the two handles it used. Duplicate the caller
397 thread's handle here, so it gets duplicated only once, when
398 launching the timer thread. Set priority of the timer thread, not
400 (getitimer): Don't duplicate the caller thread's handle here.
403 2012-11-13 Jan Djärv <jan.h.d@swipnet.se>
405 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
408 2012-11-12 Eli Zaretskii <eliz@gnu.org>
410 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
411 passed to pint2str and pint2hrstr to be at most the size of the
412 frame's decode_mode_spec_buffer. This avoids crashes with very
413 large values of FIELD_WIDTH argument to decode_mode_spec.
416 2012-11-07 Martin Rudalics <rudalics@gmx.at>
418 * window.c (Fsplit_window_internal): Set combination limit of
419 new parent window to t iff Vwindow_combination_limit is t;
420 fixing a regression introduced with the change from 2012-09-22.
421 (Fwindow_combination_limit, Fset_window_combination_limit):
424 2012-11-06 Eli Zaretskii <eliz@gnu.org>
426 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
427 amount when the scroll margins are too large. When scrolling
428 backwards in the buffer, give up if cannot reach point or the
429 scroll margin within a reasonable number of screen lines.
430 Fixes point position in window under scroll-up/down-aggressively when
431 point is positioned many lines beyond the window top/bottom.
434 2012-11-05 Eli Zaretskii <eliz@gnu.org>
436 * ralloc.c (relinquish): If real_morecore fails to return memory
437 to the system, don't crash; instead, leave the last heap
438 unchanged and return. (Bug#12774)
440 2012-11-03 Eli Zaretskii <eliz@gnu.org>
442 * lisp.mk: Adjust comments to the fact that term/internal is now
443 loaded from loadup.el.
445 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
446 (msdos_fatal_signal): New function.
447 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
450 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
451 for GCC versions before 4.
452 (emacs_raise): Define to call msdos_fatal_signal.
454 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
455 iterator when starting in the middle of a display or overlay
458 2012-11-03 Jan Djärv <jan.h.d@swipnet.se>
460 * widget.c (resize_cb): New function.
461 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
462 (EmacsFrameResize): Check if all is up to date before changing frame
465 2012-11-01 Eli Zaretskii <eliz@gnu.org>
467 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
469 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
471 Fix crash when using Emacs as commit editor for git (Bug#12697).
472 * callproc.c (setpgrp): Remove macro, as we now use setpgid
473 and it is configured in conf_post.h.
474 (Fcall_process): Don't invoke both setsid and setpgid; the former
475 is enough, if it exists.
476 * callproc.c (Fcall_process, child_setup):
477 * process.c (create_process): Use setpgid.
478 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
480 * dispnew.c (init_display): Initialize the foreground group
481 if we are running a tty display.
482 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
483 * lisp.h (init_foreground_group): New decl.
484 * sysdep.c (inherited_pgroup): New static var.
485 (init_foreground_group, tcsetpgrp_without_stopping)
486 (narrow_foreground_group, widen_foreground_group): New functions.
487 (init_sys_modes): Narrow foreground group.
488 (reset_sys_modes): Widen foreground group.
490 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
492 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
494 2012-10-31 Martin Rudalics <rudalics@gmx.at>
496 * minibuf.c (read_minibuf): Restore current buffer since
497 choose_minibuf_frame calling Fset_frame_selected_window may
498 change it (Bug#12766).
500 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
502 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
504 2012-10-30 Kenichi Handa <handa@gnu.org>
506 * font.c (Ffont_at): If WINDOW is specified and it is not
507 displaying the current buffer, signal an error.
509 2012-10-29 Daniel Colascione <dancol@dancol.org>
511 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
512 In preparation for fixing bug#12739, move these functions from
515 * coding.h, coding.c: ... to here, and compile them only when
516 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
517 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
519 2012-10-28 Eli Zaretskii <eliz@gnu.org>
521 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
522 (timer_loop, getitimer, setitimer): Use it instead of
523 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
525 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
528 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
530 * nsterm.m (NO_APPDEFINED_DATA): New define.
531 (last_appdefined_event_data): New variable
532 (last_appdefined_event): Remove.
533 (ns_select): Initialize t from last_appdefined_event_data instead
534 of [last_appdefined_event data1].

536 remove last_appdefined_event (Bug#12698).
538 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
540 * frame.c (x_set_font): Catch internal error.
542 2012-10-27 Eli Zaretskii <eliz@gnu.org>
544 Avoid overflow in w32 implementation of interval timers.
545 When possible, for ITIMER_PROF count only times the main thread
547 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
548 'volatile ULONGLONG' types. All the other data which was
549 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
550 (GetThreadTimes_Proc): New typedef.
551 (w32_get_timer_time): New function, returns a suitable time value
553 (timer_loop): Enter critical section when accessing ULONGLONG
554 values of the itimer_data struct, as these accesses are no longer
555 atomic. Call 'w32_get_timer_time' instead of 'clock'.
556 Remove unused variable.
557 (init_timers): Initialize s_pfn_Get_Thread_Times.
558 (start_timer_thread): Don't assign itimer->caller_thread here.
559 (getitimer): Assign itimer->caller_thread here.

565 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
566 mouse movement events if the menu bar is active. This avoids
567 producing a busy "hour-glass" cursor by Windows if the mouse
568 pointer is positioned over a tooltip shown for some menu item.
570 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
572 Don't assume process IDs fit in int.
573 * emacs.c (shut_down_emacs) [!DOS_NT]:
574 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
575 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
576 Use pid_t, not int, to store process IDs, as 'int'
577 is not wide enough on a few platforms (e.g., AIX and IRIX).
579 2012-10-23 Kenichi Handa <handa@gnu.org>
581 The following change is to make face-font-rescale-alist work

607 * frame.c (Fmouse_position, Fmouse_pixel_position):
608 * xdisp.c (produce_stretch_glyph):
609 Declare local vars only when they're needed.
610 This is clearer and avoids a warning on OpenBSD about unused vars.
611 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
612 This is safer, and avoids OpenBSD warnings about unused vars.
613 * keyboard.c (record_menu_key): Remove unnecessary decl.
614 (poll_timer): Define only if POLL_FOR_INPUT is defined.
615 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
616 as our definition clashes with OpenBSD's.
617 * xfaces.c (load_face_colors, check_lface_attrs)
618 (get_lface_attributes_no_remap, get_lface_attributes)
619 (lface_fully_specified_p, x_supports_face_attributes_p)
620 (tty_supports_face_attributes_p, face_fontset, realize_face)
621 (realize_x_face, realize_tty_face):
622 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
623 merely Lisp_Object *. This is more informative and avoids
624 a warning on OpenBSD about accessing beyond an object's size.
626 2012-10-20 Chong Yidong <cyd@gnu.org>
628 * lread.c (Fload): Doc fix (Bug#12592).

654 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
655 (staticpro): If we run out of staticpro slots, die with an
656 informative error instead of just calling emacs_abort.

973 * xdisp.c (start_hourglass): Call w32_note_current_window when
974 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
975 build that caused Emacs to display the hourglass cursor forever.
977 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
978 which is broken under remote desktop, calculate the number of
979 colors available for a display based on the display's number of

1019 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
1020 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
1021 accidental message numbering hole. Change other messages to
1024 * w32select.h (HAVE_W32SELECT): Remove.
1026 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
1027 w32common.h instead of w32heap.h.
1029 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
1030 (get_allocation_unit, get_processor_type, get_w32_major_version)
1031 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1032 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1033 (OS_NT, os_subtype, cache_system_info): Move declarations to
1036 * w32heap.c: Include w32common.h.
1037 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
1038 (w32_minor_version, w32_build_number, w32_subtype):
1039 Remove duplicate definitions.
1041 * w32fns.c: Include w32common.h; include w32heap.h only in
1044 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
1045 Use `report_file_error' instead of `error' in order to better
1046 inform users of what went wrong. Increase NTGUI_UNICODE file
1047 dialog box file name length to 32k, the maximum allowed by the NT
1050 * w32common.h: New file.
1051 (ROUND_UP, ROUND_DOWN, get_page_size)
1052 (get_allocation_unit, get_processor_type, get_w32_major_version)
1053 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1054 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1055 (OS_NT, os_subtype, cache_system_info): Move here.
1057 * unexw32.c, unexcw.c: Include w32common.h.
1059 * emacs.c (main): Use (defined (WINDOWSNT) || defined
1060 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
1061 to call syms_of_w32select.
1063 * cygw32.h: Remove obsolete EXFUN declarations.
1065 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
1067 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
1068 of w32inevt.o from SOME_MACHINE_OBJECTS.
1070 2012-10-08 Daniel Colascione <dancol@dancol.org>
1072 * image.c: Permanent fix for JPEG compilation issue --- limit
1073 jpeglib `boolean' redefinition to Cygwin builds.
1075 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1077 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
1079 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
1082 2012-10-08 Daniel Colascione <dancol@dancol.org>
1084 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1085 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
1086 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
1087 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
1088 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1089 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1090 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1091 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1092 now a supported configuration.
1094 * Makefile.in: consolidate image variables into LIBIMAGE; add
1095 W32_OBJ and W32_LIBS. Compile new files.
1098 (_DebPrint) declare tracing facility for W32 debugging. We need
1099 to unify tracing later.
1101 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1102 unconditional use of W32 Unicode functions. Cygwin runs only on
1103 100% Unicode operating systems.
1105 * cygw32.c: New file. Define Cygwin-specific facilities.
1106 (Fcygwin_convert_path_to_windows)
1107 (Fcygwin_convert_path_from_windows): New user functions for
1108 accessing Cygwin path-munging routines.
1110 * cygw32.h: New file.
1111 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1112 UTF-16LE strings temporarily inside non-Lisp-visible string
1115 (w32_strerror): Just what it says on the tin.
1117 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1118 also run for Cygwin; both systems have the same problem with using
1119 GUI facilities in a forked child. Also call syms_of_cygw32,
1120 syms_of_w32select in correct places.
1122 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1123 needs fork-then-exec for daemon launching.
1125 * font.h: Include frame.h.
1127 * image.c: Use the image library cache machinery only when we're
1128 compiling for native WINDOWSNT; Cygwin can use shared libraries
1129 like any other Unixlike system.
1131 * keyboard.c: Clarify a comment regarding the input loop.
1133 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1134 functions directly instead of trying to detect at runtime that our
1135 host operating system supports them. We make this change for two
1136 reasons: Cygwin lacks support for the multibyte character
1137 conversion functions used by the legacy menu code, and Cygwin
1138 never needs to rely on non-Unicode APIs.
1140 * unexw32.c (hinst): Declare extern.
1142 * w32.c: Change header order;
1143 (w32_strerror): Move to w32fns.c because we need it for
1144 non-WINDOWSNT builds.
1146 * w32.h: Add #error macro to make sure we don't include w32.h for
1147 Cygwin builds. Remove w32select declarations.
1149 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1150 w32fns.c. w32console.c is WINDOWSNT-only.
1152 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1153 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1155 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1156 (w32_major_version, w32_minor_version, w32_build_number)
1157 (os_subtype, sound_type): Define here
1158 (w32_defined_color): Make color parameter const for consistency
1159 with other _defined_color functions.
1160 (w32_createwindow): Unconditionally call w32_init_class instead of
1161 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1162 through the code is complex and unnecessary because class
1163 registration is practically free.
1164 (w32_name_of_message): New EMACSDEBUG-only function.
1165 (Fset_message_beep): Move here
1166 (Fx_open_connection): Require that the display name for Windows be
1167 "w32" for consistency, emacsclient disambiguation, and maybe, one
1168 day, multi-window-system support.
1169 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1170 Cygwin files for W32 GUI facilities, since these clearly don't
1171 expect Cygwin names.
1172 (_DebPrint): Define.
1173 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1174 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1175 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1176 (w32_last_error): Remove.
1178 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1180 * w32heap.c (syspage_mask): Declare here.
1181 (cache_system_info): Remove.
1183 * w32inevt.c (faked_key): Define globally, not statically.
1184 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1185 (w32_console_toggle_lock_key): Move to w32fns.c.
1187 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1189 * w32proc.c (_DebPrint): Move to w32fns.c.
1190 * w32select.c: Include string.h, stdio.h for Cygwin.
1191 * w32select.h: New File.
1193 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1195 (w32_message_fd): New variable. Under Cygwin, holds the file
1196 descriptor the system used to tell us about pending thread
1199 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1200 that prevented compilation under non-WINDOWSNT systems.
1202 (w32_initialize): Open /dev/windows and assign it to
1203 w32_message_fd. Provide w32 feature.
1205 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1206 (WM_EMACS_INPUT_READY): add.
1207 (prepend_msg, w32_message_fd): Declare globally.
1210 (keyboard_handle): Use only when WINDOWSNT.
1211 (notify_msg_ready): New function. Posts a message to the main
1212 thread's message queue under CYGWIN, which wakes up the main
1213 thread from select(2) by making the /dev/windows file descriptor
1214 ready. Under WINDOWSNT, it sets an event the same way the old
1217 (post, prepend_msg): Actually call notify_msg_ready instead of
1218 setting the input event directly.
1220 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1222 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1223 but it still has blocs in it, don't return it to the system,
1224 instead of aborting. (Bug#12402)
1226 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1228 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
1230 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
1231 MAC_OS_X_VERSION_10_6.
1232 (syms_of_nsterm): Remove comment about Panther and above for
1234 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
1235 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
1236 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
1238 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
1239 MAC_OS_X_VERSION_10_4.
1241 * nsmenu.m (fillWithWidgetValue:): Remove code for <
1242 MAC_OS_X_VERSION_10_2.
1244 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
1246 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
1247 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
1249 * nsterm.m (ns_in_resize): Remove (Bug#12479).
1250 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
1251 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
1252 Remove ns_in_resize check.
1253 (ns_clear_frame_area): Remove resize handle code.
1255 * nsfns.m (ns_in_resize): Remove.
1256 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
1257 Remove ns_in_resize check.
1259 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
1261 Improve sys_siglist detection.
1262 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
1263 defined as a macro, as is done in Solaris.
1264 (sys_siglist_entries): New macro.
1265 (save_strsignal): Use it.
1266 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1267 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1269 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1271 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1272 fullscreen/Fullscreen.
1274 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1275 tobar_height is new.
1277 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1278 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1279 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
1280 (windowDidResize:): Check for correct window if old style fullscreen.
1281 Capitalize word in comment. Remove incorrect comment.
1282 (initFrameFromEmacs:): tbar_height renamed tibar_height.
1283 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
1284 error in drawing background.
1285 (toggleFullScreen:): Remove comment. Rearrange calls.
1286 Set toolbar values to zero, save old height in tobar_height.
1287 Restore tool bar height when leaving fullscreen.
1288 (canBecomeMainWindow): New function.
1290 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
1292 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
1294 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1296 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1298 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1299 that time stamps of directories could also be changed.
1300 Don't request the too broad GENERIC_WRITE, only the more restrictive
1301 FILE_WRITE_ATTRIBUTES access rights.
1303 * fileio.c (Fset_file_times): Special-case ignoring errors for
1304 directories only on MSDOS, not on MS-Windows.
1306 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1308 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1310 2012-10-04 Eli Zaretskii <eliz@gnu.org>
1312 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
1313 see whether CreateFile failed.
1315 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1317 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1318 to avoid similar races.
1319 * keyboard.c (pending_signals): Now bool, not int.
1321 Port timers to OpenBSD, plus check for timer failures.
1322 OpenBSD problem reported by Han Boetes.
1323 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1325 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1326 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1327 like OpenBSD, which has timer_settime but does not declare it.
1328 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1329 whether to use itimerspec-related primitives. All uses of
1330 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1332 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1334 * profiler.c (handle_profiler_signal): Fix a malloc race
1335 that caused Emacs to hang on Fedora 17 when profiling Lisp.
1337 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
1339 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1341 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1343 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1344 consistent with the change in return value of 'safe_strsignal'.
1346 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1348 Prefer plain 'static' to 'static inline' (Bug#12541).
1349 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1350 (bidi_set_sor_type, bidi_push_embedding_level)
1351 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
1352 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
1353 (bidi_cache_search, bidi_cache_ensure_space)
1354 (bidi_cache_iterator_state, bidi_cache_find)
1355 (bidi_peek_at_next_level, bidi_set_paragraph_end)
1356 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1357 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1358 Now 'static', not 'static inline'.
1360 Count overruns when profiling; change units to ns.
1361 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1362 Give extra weight to samples after overruns, to attempt to count
1363 the time more accurately.
1364 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1365 the underlying primitives nominally do ns.
1366 (Fprofiler_cpu_start): Document the change. Mention that
1367 the sampling intervals are only approximate.
1369 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1371 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1373 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1374 case for the special 0 coding-system.
1376 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1377 (Fmake_overlay): Remove redundant tests.
1378 (fix_start_end_in_overlays): Remove redundant recentering.
1380 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1382 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1383 Update dependencies.
1385 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1387 Fix a malloc race condition involving strsignal.
1388 A signal can arrive in the middle of a malloc, and Emacs's signal
1389 handler can invoke strsignal, which can invoke malloc, which is
1390 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1391 Fix it by altering the signal handler so that it does not invoke
1393 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1394 * process.c (status_message): Use const pointer, in case strsignal
1395 is #defined to safe_strsignal.
1396 * sysdep.c (sys_siglist, init_signals): Always define and
1397 initialize a substitute sys_siglist if the system does not define
1398 one, even if HAVE_STRSIGNAL.
1399 (safe_strsignal): Rename from strsignal. Always define,
1400 using sys_siglist. Return a const pointer.
1401 * syssignal.h (safe_strsignal): New decl.
1402 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1404 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1406 * w32proc.c (timer_loop): Fix code that waits for timer
1407 expiration, to avoid high CPU usage.
1409 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1411 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1412 (sweep_weak_table): Remove redundant prototypes.
1414 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1416 * emacs.c: Move the inclusion of TERM_HEADER after including
1417 windows.h on WINDOWSNT. This avoids compilation problems with
1420 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1422 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1423 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1424 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1425 as the previous version used 'void *'.
1427 * ralloc.c (ROUNDUP): Fix last change.
1428 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1431 * w32proc.c <disable_itimers>: New static flag.
1432 (init_timers): Initialize it to zero, after creating the critical
1433 sections used by the timer threads.
1434 (term_timers): Set to 1 before deleting the critical sections.
1435 (getitimer, setitimer): If disable_itimers is non-zero, return an
1436 error indication without doing anything. Reported by Fabrice
1437 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1438 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1440 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1443 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1444 term_ntproc after all the other bookkeeping, to get timers working
1445 as long as possible.
1447 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1449 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1450 Suggested by Juri Linkov in
1451 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1453 Prefer plain 'static' to 'static inline' (Bug#12541).
1454 With static functions, modern compilers inline pretty well by
1455 themselves; advice from programmers often hurts as much as it helps.
1456 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1457 this change shrinks the text size of the Emacs executable by 1.1%
1458 without affecting CPU significantly in my benchmark.
1459 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
1460 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
1461 (mark_maybe_object, mark_maybe_pointer, bounded_number):

1760 Prefer timer_settime if available, and prefer
1761 thread cputime clocks, then process cputime clocks, then

1763 to round more-correctly when falling back to setitimer.
1764 (Fprofiler_cpu_start): Use it.
1765 (Fprofiler_cpu_stop): Prefer timer_settime if available.

1831 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1832 Since this stuff is now private to charset.c, there's no need for
1833 a public macro and no need to inline by hand.

1943 now return bool, not int. All uses changed.
1944 * image.c: Omit unnecessary static decls.
1945 (x_create_bitmap_mask, x_build_heuristic_mask):
1946 Return void, not int, since callers don't care about the return value.

1981 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1983 Move pid_t related decls out of lisp.h.
1984 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1985 (interruptible_wait_for_termination):
1986 Move these decls from lisp.h to syswait.h, since they use pid_t.
1987 Needed on FreeBSD; see Herbert J. Skuhra in
1988 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1989 * callproc.c: Include syswait.h.

2035 2012-09-23 Eli Zaretskii <eliz@gnu.org>
2037 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2038 fatal_error_backtrace.
2040 * w32proc.c (sys_kill): Undo last change: don't do anything when
2041 invoked to deliver SIGABRT to our own process. This is now
2042 handled by emacs_raise.
2044 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2046 * w32term.c (w32_read_socket): Remove leftover reference to
2047 interrupt_input_pending.
2049 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2051 Do not use SA_NODEFER.
2052 Problem reported by Dani Moncayo in
2053 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2055 * sysdep.c (emacs_abort): Do not reset signal handler.
2056 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2057 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2058 wanted even on POSIXish hosts, and it doesn't work on Windows.
2060 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2062 * xterm.c (x_term_init): Call fixup_locale before and after calling
2063 gtk_init (Bug#12392).
2065 2012-09-23 Chong Yidong <cyd@gnu.org>
2067 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2068 Vdynamic_library_alist.
2070 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2071 (Fgnutls_available_p): Caller changed.
2073 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2074 (Flibxml_parse_xml_region): Likewise.
2076 * dispextern.h (struct image_type): Remove arg from init function.
2078 * image.c (Finit_image_library, lookup_image_type)
2079 (define_image_type): Remove now-unneeded second arg.
2080 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2081 (init_tiff_functions, init_gif_functions, init_svg_functions):
2082 Arglist and w32_delayed_load calling convention changed.
2083 (gs_type): Remove init_gs_functions; there is no such function.
2084 (valid_image_p, make_image): Fix caller to lookup_image_type.
2086 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2088 Simplify and avoid signal-handling races (Bug#12471).
2090 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2091 Avoid recursive loop if there's a fatal error in the function itself.
2092 * atimer.c (pending_atimers):
2093 * blockinput.h: Don't include "atimer.h"; no longer needed.
2094 (interrupt_input_pending): Remove. All uses removed.
2095 pending_signals now counts both atimers and ordinary interrupts.
2096 This is less racy than having three separate pending-signal flags.
2097 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2099 Rename from their upper-case counterparts BLOCK_INPUT,
2100 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2101 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2102 This makes it easier to access volatile variables more accurately.
2103 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2104 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2105 that's more reliable if the code is buggy and sets
2106 interrupt_input_blocked to a negative value. All uses changed.
2107 * atimer.c (deliver_alarm_signal):
2108 Remove. No need to deliver this to the parent; any thread can
2109 handle this signal now. All uses replaced by underlying handler.
2110 * atimer.c (turn_on_atimers):
2111 * dispnew.c (handle_window_change_signal):
2112 * emacs.c (handle_danger_signal):
2113 * keyboard.c (kbd_buffer_get_event):
2114 Don't reestablish signal handler; not needed with sigaction.
2115 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2117 Rework to avoid unnecessary accesses to volatile variables.
2118 (UNBLOCK_INPUT_TO): Now a function.
2119 (totally_unblock_input, unblock_input): New decls.
2120 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2121 (init_data): Remove. Necessary stuff now done in init_signal.
2122 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2123 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2124 (fatal_error_code): Remove; no longer needed.
2125 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2126 it doesn't always backtrace. All uses changed. No need to reset
2127 signal to default, since sigaction and/or die does that for us now.
2128 Use emacs_raise (FOO), not kill (getpid (), FOO).
2129 (main): Check more-accurately whether we're dumping.
2130 Move fatal-error setup to sysdep.c
2131 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2132 * gtkutil.c (xg_get_file_name, xg_get_font):
2133 Remove no-longer-needed signal-mask manipulation.
2134 * keyboard.c, process.c (POLL_FOR_INPUT):
2135 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2136 * keyboard.c (read_avail_input): Remove.
2137 All uses replaced by gobble_input.
2138 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2139 (kbd_buffer_store_event_hold, gobble_input):
2140 (record_asynch_buffer_change) [USABLE_SIGIO]:
2141 (store_user_signal_events):
2142 No need to mess with signal mask.
2143 (gobble_input): If blocking input and there are terminals, simply
2144 set pending_signals to 1 and return. All hooks changed to not
2145 worry about whether input is blocked.
2146 (process_pending_signals): Clear pending_signals before processing
2147 them, in case a signal comes in while we're processing.
2148 By convention callers now test pending_signals before calling us.
2149 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2150 New functions, to support changes to blockinput.h.
2151 (handle_input_available_signal): Now extern.
2152 (reinvoke_input_signal): Remove. All uses replaced by
2154 (quit_count): Now volatile, since a signal handler uses it.
2155 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2156 All callers changed. Block SIGINT only if not already blocked.
2157 Clear sigmask reliably, even if Fsignal returns, which it can.
2158 Omit unnecessary accesses to volatile var.
2159 (quit_throw_to_read_char): No need to restore sigmask.
2160 * keyboard.c (gobble_input, handle_user_signal):
2161 * process.c (wait_reading_process_output):
2162 Call signal-handling code rather than killing ourselves.
2163 * lisp.h: Include <float.h>, for...
2164 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2165 (pending_signals): Now volatile.
2166 (syms_of_data): Now const if IEEE floating point.
2167 (handle_input_available_signal) [USABLE_SIGIO]:
2168 (terminate_due_to_signal, record_child_status_change): New decls.
2169 * process.c (create_process): Avoid disaster if memory is exhausted
2170 while we're processing a vfork, by tightening the critical section
2172 (send_process_frame, process_sent_to, handle_pipe_signal)
2173 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2175 (send_process): No need for setjmp/longjmp any more, since the
2176 SIGPIPE stuff is now gone. Instead, report an error if errno
2178 (record_child_status_change): Now extern. PID and W are now args.
2179 Return void, not bool. All callers changed.
2180 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2181 Remove. All uses removed. This bug should be fixed now in a
2183 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2184 and record the child status change directly. This avoids the
2185 need to futz with the signal mask.
2186 (process_fatal_action): Move here from emacs.c.
2187 (emacs_sigaction_flags): New function, containing
2188 much of what used to be in emacs_sigaction_init.
2189 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2190 caught by emacs, to make races less likely.
2191 (deliver_process_signal): Rename from handle_on_main_thread.
2193 (BACKTRACE_LIMIT_MAX): Now at top level.
2194 (thread_backtrace_buffer, threadback_backtrace_pointers):
2196 (deliver_thread_signal, deliver_fatal_thread_signal):
2197 New functions, for more-accurate delivery of thread-specific signals.
2198 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2199 (deliver_arith_signal): Handle in this thread, not
2200 in the main thread, since it's triggered by this thread.
2201 (maybe_fatal_sig): New function.
2202 (init_signals): New arg DUMPING so that we can be more accurate
2203 about whether we're dumping. Caller changed.
2204 Treat thread-specific signals differently from process-general signals.
2205 Block all signals while handling fatal error; that's safer.
2206 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2208 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2209 Ignore SIGPIPE unless batch.
2210 (emacs_backtrace): Output backtrace for the appropriate thread,
2211 which is not necessarily the main thread.
2212 * syssignal.h: Include <stdbool.h>.
2213 (emacs_raise): New macro.
2214 * xterm.c (x_connection_signal): Remove; no longer needed
2215 now that we use sigaction.
2216 (x_connection_closed): No need to mess with sigmask now.
2217 (x_initialize): No need to reset SIGPIPE handler here, since
2218 init_signals does this for us now.
2220 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2222 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2223 background rect may be larger (Bug#12245).
2225 2012-09-23 Chong Yidong <cyd@gnu.org>
2227 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2229 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2231 * .gdbinit: Just stop at fatal_error_backtrace.
2232 See Stefan Monnier's request in
2233 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2234 Remove no-longer-used query of system type.
2236 2012-09-22 Chong Yidong <cyd@gnu.org>
2238 * search.c (Freplace_match): Doc fix (Bug#12325).
2240 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2242 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2243 (Fline_end_position): Doc fix.

2250 initialization function.
2252 * image.c (define_image_type): Call the image initializer function
2253 if it is defined. Arguments and return value changed.
2254 (valid_image_p, make_image): Callers changed.
2255 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2256 (gif_type, imagemagick_type, svg_type, gs_type):
2257 Add initialization functions.
2258 (Finit_image_library): Call lookup_image_type.
2259 (CHECK_LIB_AVAILABLE): Macro deleted.
2260 (lookup_image_type): Call define_image_type here, rather than via
2261 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2262 (syms_of_image): Move define_image_type calls for xbm_type and
2263 pbm_type to lookup_image_type.
2265 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2267 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2268 'idle_timers' from here ...
2269 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2270 lists, to avoid infloops when the timer does something stupid,
2271 like reinvoke itself with the same or smaller time-out.
2274 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2276 * window.c (Fsplit_window_internal): Handle only Qt value of
2277 Vwindow_combination_limit separately.
2278 (Qtemp_buffer_resize): New symbol.
2279 (Vwindow_combination_limit): New default value.
2282 2012-09-22 Eli Zaretskii <eliz@gnu.org>

2285 the new overlay string. (Bug#10159)
2287 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2289 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2290 or that fprintf is async-signal-safe. POSIX doesn't require
2293 2012-09-22 Chong Yidong <cyd@gnu.org>
2295 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2298 2012-09-22 Kenichi Handa <handa@gnu.org>
2300 * composite.c (composition_reseat_it): Handle the case that a
2301 grapheme cluster is not covered by a single font (Bug#12352).
2303 2012-09-21 Chong Yidong <cyd@gnu.org>
2305 * image.c (define_image_type): Avoid adding duplicate types to
2306 image_types (Bug#12463). Suggested by Jörg Walter.
2308 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2310 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2311 (print_load_command_name): Add case LC_DATA_IN_CODE.
2312 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

2316 * eval.c (Frun_hook_with_args_until_success)
2317 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2319 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2321 * fileio.c (Ffile_selinux_context): Only call freecon when
2322 lgetfilecon succeeded.
2323 (Fset_file_selinux_context): Likewise. (Bug#12444)
2325 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2327 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2328 reordering, locate the cursor by calling set_cursor_from_row; if
2329 that fails, clear the desired glyph matrix before returning a
2330 failure indication to the caller. Fixes leaving garbled display
2331 when fast scrolling with a down-key. (Bug#12403)
2332 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2333 scrolling through multibyte text.
2335 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2337 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2338 calling mark_vectorlike since that's the one that marks the window.
2339 (mark_discard_killed_buffers): Mark the final cdr.
2340 * window.h (struct window): Move prev/next_buffers to the
2341 non-standard fields.
2342 * window.c (make_window): Initialize prev/next_buffers manually.
2344 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2346 Omit unused arg EXPECTED from socket hooks.
2347 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):

2352 * xterm.c (XTread_socket):
2353 Omit unused arg EXPECTED. All callers changed.
2354 (store_user_signal_events): Return void, not int, since callers no
2355 longer care about the return value. All uses changed.
2357 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2359 * w32gui.h (XParseGeometry): Do not declare.
2361 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2363 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2364 Ignore 'expected'. See Eli Zaretskii in
2365 <http://bugs.gnu.org/12471#8> (last line).
2367 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2368 (XParseGeometry): Now static. Substitute extremal values for
2369 values that are out of range.
2371 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2373 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2375 * nsfns.m (XParseGeometry): Remove.
2376 (Fx_create_frame): Call x_set_offset to correctly interpret
2377 top_pos in geometry.
2379 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2380 (Fx_parse_geometry): If there is a space in string, call
2381 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2383 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2385 * search.c (scan_buffer): Use character positions in calls to
2386 region_cache_forward and region_cache_backward, not byte
2387 positions. (Bug#12196)
2389 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2390 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2392 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2393 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2394 emacs_blocked_malloc, now deleted.
2396 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2398 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2399 The workaround was for improving performance on Solaris 2.4, but
2400 is getting in the way now. Emacs will still work if someone is
2401 still running Solaris 2.4 in a museum somewhere; Sun dropped
2402 support for Solaris 2.4 in 2003.
2403 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2404 * process.c (create_process) [HAVE_WORKING_VFORK]:
2405 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2406 since Emacs no longer uses vfork on that platform.
2408 2012-09-17 Glenn Morris <rgm@gnu.org>
2410 * emacs.c: Use COPYRIGHT.
2412 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2414 Remove configure's --without-sync-input option (Bug#12450).
2415 When auditing signal-handling in preparation for cleaning it up,
2416 I found that SYNC_INPUT has race conditions and would be a real
2417 pain to fix. Since it's an undocumented and deprecated
2418 configure-time option, now seems like a good time to remove it.
2419 Also see <http://bugs.gnu.org/11080#16>.
2420 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2421 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2422 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2423 (malloc_hysteresis):
2424 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2425 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2426 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2427 (dont_register_blocks, bytes_used_when_reconsidered)
2428 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2429 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2430 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2431 Remove. All uses removed.
2432 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2433 implementation, one that depends on whether the new macro
2434 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2436 * atimer.c (run_timers, handle_alarm_signal):
2437 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2438 (handle_async_input, process_pending_signals)
2439 (handle_input_available_signal, init_keyboard):
2440 * nsterm.m (ns_read_socket):
2441 * process.c (wait_reading_process_output):
2442 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2443 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2445 * xterm.c (XTread_socket):
2447 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2448 * eval.c (handling_signal): Remove. All uses removed.
2449 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2450 All uses replaced with the SYNC_INPUT version.
2451 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2453 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2456 * font.c (Ffont_shape_gstring): Remove unused local.
2458 2012-09-16 Glenn Morris <rgm@gnu.org>
2460 * Makefile.in (clean): No longer run nextstep's clean.
2462 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2464 (ns-app): Move here from ns.mk, and simplify.
2465 (clean): Simplify nextstep entry.
2466 * ns.mk: Remove file.
2468 2012-09-17 Kenichi Handa <handa@gnu.org>
2470 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2471 not covert the last few charactes.
2473 2012-09-16 Kenichi Handa <handa@gnu.org>
2475 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2476 here, but just check the validity of glyphs in the glyph-string.
2478 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2480 * window.c (Fwindow_parameter, Fset_window_parameter):
2481 Accept any window as argument (Bug#12452).
2483 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2485 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2486 to ns_term_init to avoid memory leak.
2488 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2489 explicit retain/release.
2490 (ns_term_init): Only allow one display. Initialize outerpool and
2493 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2495 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2496 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2497 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2498 the Microsoft problem in a different way, by altering ../nt/config.nt.
2500 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2515 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2516 by lisp.h. This completes removal of setjmp.h inclusion
2517 erroneously announced in the previous commit. (Bug#12446)
2519 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2522 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2523 not defined as a macro. The latter happens on MS-Windows.
2526 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2528 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2529 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2530 Some instances of '#include <setjmp.h>' removed, if the
2531 only reason for the instance was because "lisp.h" was included.
2532 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2533 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2534 and _longjmp with the new symbols. Emacs already uses _setjmp if
2535 available, so this change affects only POSIXish hosts that have
2536 sigsetjmp but not _setjmp, such as some versions of Solaris and
2537 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2538 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2539 (png_load_body) [HAVE_PNG]:
2540 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2541 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2542 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2543 since PNG requires jmp_buf. This is the only exception to the
2544 general rule that we now use sys_setjmp and sys_longjmp.
2545 This exception is OK since this code does not change the signal
2546 mask or longjmp out of a signal handler.
2548 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2550 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2551 Include "syssignal.h", for 'main_thread'.
2553 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2555 Avoid out-of-range marker position (Bug#12426).
2556 * insdel.c (replace_range, replace_range_2):
2557 Adjust markers before overlays, as suggested by comments.
2558 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2559 Remove redundant check before calling offset_intervals.
2561 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2563 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2564 current buffer (Bug#12387).
2566 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2568 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2570 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2572 Use a more backwards-compatible timer format (Bug#12430).
2573 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2574 vector element, not from the 4th, since PSECS is now at the end.
2575 (Fcurrent_idle_time): Doc fix.
2577 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2579 Function to mark objects and remove killed buffers at once.
2580 * alloc.c (discard_killed_buffers): Rename to ...
2581 (mark_discard_killed buffers) ... new name. Add marking
2582 of remaining objects. Fix comment. Adjust users.
2583 (mark_object): Do not touch frame buffer lists here.
2584 * frame.c (delete_frame): Reset frame buffer lists here.
2586 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2588 Better workaround for GNOME bug when --enable-gcc-warnings.
2589 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2590 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2591 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2593 Simplify SIGIO usage (Bug#12408).
2594 The code that dealt with SIGIO was crufty and confusing, e.g., it
2595 played tricks like "#undef SIGIO" but these tricks were not used
2596 consistently. Simplify mostly by not #undeffing standard symbols,
2597 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2598 or not as we please) rather than "defined SIGIO" (standard symbol
2599 that we probably shouldn't #undef).
2600 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2601 Modules that need it can include it.
2602 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2603 * dispextern.h (ignore_sigio): New decl.
2604 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2605 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2606 * emacs.c (shut_down_emacs):
2607 * keyboard.c (kbd_buffer_store_event_hold):
2608 Use ignore_sigio rather than invoking 'signal' directly.
2609 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2611 (FIONREAD, SIGIO): Do not #undef.
2612 (tty_read_avail_input): Use #error rather than a syntax error.
2613 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2614 for I_PIPE, used by SETUP_SLAVE_PTY.
2615 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2616 * sysdep.c (croak): Remove; no longer needed. This bit of
2617 temporary code, with Fred N. Fish's comment that it's temporary,
2618 has been in Emacs since at least 1992!
2619 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2620 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2621 * syssignal.h (croak): Remove decl.
2622 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2623 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2624 now that we're termios-only.
2625 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2626 * term.c (dissociate_if_controlling_tty): Use #error rather than
2629 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2630 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2631 to work around GNOME bug 683906.
2632 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2633 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2634 This works around GCC bug 54561.
2636 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2638 More fixes for 'volatile' and setjmp/longjmp.
2639 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2640 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2641 (png_load_body) [HAVE_PNG]:
2642 (jpeg_load_body) [HAVE_JPEG]:
2643 New function, with most of the old parent function's body.
2644 (png_load) [HAVE_PNG]:
2645 (jpeg_load) [HAVE_JPEG]:
2646 Invoke the new function, to avoid longjmp munging our locals.
2647 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2648 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2649 longjmp is passed 2, as the C standard doesn't guarantee this.
2650 Instead, store the failure code into mgr->failure_code.
2652 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2654 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2655 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2656 (syms_of_keyboard): Remove support for unread-command-char.
2658 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2660 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2661 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2662 violation. (Bug#12426)
2664 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2666 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2668 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2670 * eval.c: Add `inhibit-debugger'.
2671 (Qinhibit_debugger): New symbol.
2672 (call_debugger): Bind it instead of Qdebug_on_error.
2673 (maybe_call_debugger): Test Vinhibit_debugger.
2674 (syms_of_eval): Define inhibit-debugger.
2675 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2676 (syms_of_xdisp): Remove inhibit-debug-on-message.
2678 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2680 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2681 If a nonvolatile local variable is written before a _longjmp to
2682 the frame containing the variable, and is read after the _longjmp,
2683 the value read is indeterminate. Some local variables of type
2684 'struct handler' and 'struct catchtag' are used in this way, so
2685 mark each of their slots as volatile if the slot can be set before
2686 _longjmp and read afterwards.
2687 * lisp.h (struct handler): var and chosen_clause are now volatile.
2688 (struct catchtag): val, next, and pdlcount are now volatile.
2690 * bidi.c (bidi_push_it, bidi_pop_it):
2691 * fns.c (copy_hash_table):
2692 * image.c (define_image_type):
2693 * keyboard.c (kbd_buffer_store_event_hold):
2694 * process.c (Fprocess_send_eof):
2695 * xfaces.c (x_create_gc) [HAVE_NS]:
2696 * xgselect.c (xg_select):
2697 Prefer assignment to memcpy when either will do.
2699 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2700 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2701 time an item is removed. No need to mark this function 'inline';
2702 the compiler knows better than we do.
2704 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2706 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2707 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2708 to change_frame_size (Bug#12388).
2709 (windowDidResize:): Pass YES to updateFrameSize.
2711 * nsterm.h: Add delay parameter to updateFrameSize.
2713 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2715 Discard killed buffers from deleted window and frame objects.
2716 This reduces an amount of references to killed buffers and
2717 helps GC to reclaim them faster.
2718 * alloc.c (discard_killed_buffers): New function.
2719 (mark_object): Use it for deleted windows and frames.
2720 (mark_object): If symbol's value is set up for a killed buffer
2721 or deleted frame, restore its global binding.
2722 * data.c (swap_in_global_binding): Add GC notice.
2723 (swap_in_symval_forwarding): Use convenient set_blv_where.
2724 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2725 * window.h: ... to here.
2727 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2729 Convenient macro to check whether the buffer is live.
2730 * buffer.h (BUFFER_LIVE_P): New macro.
2731 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2732 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2734 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2736 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2737 composition cases (Bug#12364).
2739 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2740 overhang of succeeding glyphs overlapping box cursor.
2742 * w32term.c (x_draw_glyph_string): Likewise.
2744 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2746 Simplify, document, and port floating-point (Bug#12381).
2747 The porting part of this patch fixes bugs on non-IEEE platforms
2748 with frexp, ldexp, logb.
2749 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2751 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2752 support, by removing commented-out code and briefly listing the
2753 C89 functions excluded. The commented-out stuff was confusing
2754 maintenance, e.g., we thought we needed cbrt but it was commented out.
2755 (logb): Remove decl; no longer needed.
2756 (isfinite): New macro, if not already supplied.
2757 (isnan): Don't replace any existing macro.
2758 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2759 are present on all C89 platforms.
2760 (Ffrexp): Do not special-case zero, as frexp does the right thing
2762 (Flogb): Do not use logb, as it doesn't have the desired meaning
2763 on hosts that use non-base-2 floating point. Instead, stick with
2764 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2765 frexp, to avoid getting an unspecified result.
2767 * xdisp.c (Qinhibit_debug_on_message): Now static.
2769 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2771 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2772 NSBezierPath (Bug#12131).
2774 2012-09-10 Chong Yidong <cyd@gnu.org>
2776 * fns.c (Fdelq, Fdelete): Doc fix.
2778 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2780 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2781 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2783 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2785 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2786 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2789 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2791 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2792 left fringe if the window has a left margin. This avoids leaving
2793 traces of the cursor because its leftmost pixel is not drawn over.
2795 * dispnew.c (update_window_line): When the left margin area of a
2796 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2797 that screen line. (Bug#12277)
2799 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2801 Assume C89 or later for math functions (Bug#12381).
2802 This simplifies the code, and makes it a bit smaller and faster,
2803 and (most important) makes it easier to clean up signal handling
2804 since we can stop worring about floating-point exceptions in
2805 library code. That was a problem before C89, but the problem
2806 went away many years ago on all practical Emacs targets.
2807 * data.c, image.c, lread.c, print.c:
2808 Don't include <math.h>; no longer needed.
2809 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2810 might be autoconfigured, as that never happens.
2812 * doprnt.c (DBL_MAX_10_EXP):
2813 * print.c (DBL_DIG):
2814 Remove. C89 or later always defines these.
2815 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2816 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2817 (arith_error, domain_error, domain_error2):
2818 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2819 no longer needed -- we simply return what C returns. All uses removed.
2820 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2822 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2823 Remove. All uses expanded, as these macros are no longer used
2824 more than once and are now more trouble than they're worth.
2825 (Ftan): Use tan, not sin / cos.
2826 (Flogb): Assume C89 frexp.
2827 (fmod_float): Assume C89 fmod.
2828 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2829 (init_floatfns): Remove. All uses removed.
2831 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2833 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2834 compositeToPoint for OSX < 10.6 (Bug#12390).
2836 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2838 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2839 This produces more-accurate results.
2841 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2843 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2844 changes (Bug#12088).
2846 2012-09-08 Chong Yidong <cyd@gnu.org>
2848 * syntax.c (Fstring_to_syntax): Doc fix.
2850 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2852 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2853 in the internal border.
2854 (x_set_window_size): Remove static variables and their usage.
2855 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2856 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2857 Remove fringe/internal border adjustment (Bug#11052).
2858 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2859 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2860 (ns_fix_rect_ibw): Remove.
2861 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2862 (ns_dumpglyphs_box_or_relief): Ditto.
2863 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2865 (ns_dumpglyphs_image): Ditto.
2866 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2868 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2869 their usage. Add fringe_extended_p and its use as in other terms.
2870 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2871 scroll bar was removed.
2872 (updateFrameSize): New function.
2873 (windowDidResize): Move code to updateFrameSize and call it.
2875 * nsterm.h (EmacsView): Add updateFrameSize.
2877 2012-09-07 Chong Yidong <cyd@gnu.org>
2879 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2881 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2883 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2885 More signal-handler cleanup (Bug#12327).
2886 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2887 Problem introduced when merging patches. Noted by Eli Zaretskii in
2888 <http://bugs.gnu.org/12327#67>.
2889 * floatfns.c: Comment fix.
2890 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2891 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2892 and anyway the declaration is harmless even if SIGDANGER is not defined.
2893 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2894 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2895 source files not surprisingly expected syssignal.h to define, or
2896 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2897 Include <sys/ioctl.h>, for FIONREAD.
2898 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2899 This eliminates a problem whereby other files mysteriously had
2900 to include "syssignal.h" before including "systty.h" if they
2901 wanted to use "#ifdef SIGIO".
2903 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2905 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2907 * w32.c (sigemptyset): Empty the set.
2908 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2910 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2912 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2914 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2915 (mark_object): Likewise for frame objects.
2917 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2919 * syssignal.h (handle_on_main_thread): Always declare,
2920 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2921 This ports to platforms without HAVE_PTHREAD.
2923 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2925 Signal-handler cleanup (Bug#12327).
2926 Emacs's signal handlers were written in the old 4.2BSD style with
2927 sigblock and sigmask and so forth, and this led to some
2928 inefficiencies and confusion. Rewrite these to use
2929 pthread_sigmask etc. without copying signal sets around. Also,
2930 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2931 'signal', and instead use functions that do not attempt to take
2932 over the system name space. This patch causes Emacs's text
2933 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2934 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2935 Do not include <signal.h> or "syssignal.h", as these
2936 modules do not use signals.
2937 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2938 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2939 Do not include <signal.h>, as "syssignal.h" does that for us now.
2940 * atimer.c (sigmask_atimers): New function.
2941 (block_atimers, unblock_atimers): New functions,
2942 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2944 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2945 no longer needed here.
2946 * emacs.c (main): Inspect existing signal handler with sigaction,
2947 so that there's no need to block and unblock SIGHUP.
2948 * sysdep.c (struct save_signal): New member 'action', replacing
2949 old member 'handler'.
2950 (save_signal_handlers, restore_signal_handlers):
2951 Use sigaction instead of 'signal' to save and restore.
2952 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2953 New function. All users of 'signal' modified to use set_sighandler
2954 if they're writeonly, and to use sys_signal if they're read+write.
2955 (emacs_sigaction_init, forwarded_signal): New functions.
2956 (sys_signal): Remove. All uses replaced by calls to sigaction
2957 and emacs_sigaction_init, or by direct calls to 'signal'.
2958 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2959 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2960 all uses replaced by pthread_sigmask etc. calls.
2961 * syssignal.h: Include <signal.h>.
2962 (emacs_sigaction_init, forwarded_signal): New decls.
2963 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2964 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2965 (sigmask, sys_sigmask): Remove; no longer needed.
2966 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2967 (sigblock, sigunblock, sigfree):
2968 (sigsetmask) [!defined sigsetmask]:
2969 Remove. All uses replaced by pthread_sigmask.
2970 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2971 no longer need to be replaced, and its typical old uses
2972 are now done via emacs_sigaction_init and sigaction.
2973 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2974 (sys_sigdel): Remove; unused.
2975 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2977 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2979 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2980 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2982 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2984 Explicitly mark buffer_defaults and buffer_local_symbols.
2985 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2986 mark_local_symbols here.
2987 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2988 since special buffers aren't marked here any more.
2989 (allocate_buffer): Chain new buffer with all_buffers here...
2990 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2992 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2993 (syms_of_buffer): Remove staticpro of the above.
2994 (init_buffer_once): Set names for buffer_defaults and
2995 buffer_local_symbols.
2997 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2999 Use bool for booleans in font-related modules.
3000 * font.c (font_intern_prop, font_style_to_value)
3001 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3002 (generate_otf_features, font_check_otf_features, font_check_otf)
3003 (font_match_p, font_list_entities, font_at):
3004 * fontset.c (fontset_id_valid_p, reorder_font_vector
3005 (fontset_find_font, Fset_fontset_font)
3006 (face_suitable_for_char_p) [0]:
3007 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3008 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3009 (m17n_flt_initialized, ftfont_shape_by_flt):
3010 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3011 * nsfont.m (nsfont_draw):
3012 * w32font.c (w32font_draw):
3013 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3014 Use bool for booleans.
3015 * font.h: Adjust to above API changes.
3016 (struct font, struct font_driver, struct font_driver_list):
3017 Use bool for booleans.
3018 (struct font): Remove useless member encoding_type.
3020 * fontset.c, xftfont.c: Omit unnecessary static decls.
3022 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3024 * alloc.c (mark_object): Revert window marking code
3025 since it's unsafe for the Fset_window_configuration.
3027 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3029 Fix race conditions with signal handlers and errno (Bug#12327).
3030 Be more systematic about preserving errno whenever a signal
3031 handler returns, even if it's not in the main thread. Do this by
3032 renaming signal handlers to distinguish between signal delivery
3033 and signal handling. All uses changed.
3034 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3035 * data.c (deliver_arith_signal): Rename from arith_error.
3036 * dispnew.c (deliver_window_change_signal): Rename from
3037 window_change_signal.
3038 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3039 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3040 * keyboard.c (deliver_input_available_signal): Rename from
3041 input_available_signal.
3042 (deliver_user_signal): Rename from handle_user_signal.
3043 (deliver_interrupt_signal): Rename from interrupt_signal.
3044 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3045 (deliver_child_signal): Rename from sigchld_handler.
3046 * atimer.c (handle_alarm_signal):
3047 * data.c (handle_arith_signal):
3048 * dispnew.c (handle_window_change_signal):
3049 * emacs.c (handle_fatal_signal, handle_danger_signal):
3050 * keyboard.c (handle_input_available_signal):
3051 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3052 * process.c (handle_pipe_signal, handle_child_signal):
3053 New functions, with the actual signal-handling code taken from the
3054 original respective signal handlers, sans the sporadic attempts to
3055 preserve errno, since that's now done by handle_on_main_thread.
3056 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3057 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3058 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3060 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3061 Move initialization of main_thread to sysdep.c's init_signals.
3062 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3063 our usage, and simplifies the mainline code.
3064 (record_child_status_change): New static function, as a helper
3065 for handle_child_signal, and with most of the old child handler's
3067 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3068 (handle_child_signal): Use the above.
3069 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3070 Moved here from emacs.c.
3071 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3072 code moved here from emacs.c's main function.
3073 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3074 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3075 This lets callers save and restore errno properly.
3077 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3079 Remove redundant or unused things here and there.
3080 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3081 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3082 * editfns.c (Fcompare_buffer_substrings): Likewise.
3083 * frame.h (struct terminal, struct font_driver_list):
3084 Remove redundant declarations.
3085 * window.h (Qleft, Qright): Likewise.
3087 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3089 Do not mark objects from deleted buffers, windows and frames.
3090 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3091 (mark_object): Likewise for windows and frames.
3093 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3095 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3096 buffer_defaults and buffer_local_symbols as valid objects.
3097 Return special value to denote them.
3099 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3101 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3102 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3103 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3104 (file_name_absolute_p, Fsubstitute_in_file_name):
3105 (check_executable, check_writable, Ffile_accessible_directory_p)
3106 (Fset_file_selinux_context, Fdefault_file_modes)
3107 (Finsert_file_contents, choose_write_coding_system)
3108 (Fwrite_region, build_annotations, a_write, e_write)
3110 * filelock.c (boot_time_initialized, get_boot_time)
3111 (get_boot_time_1, lock_file_1, within_one_second):
3112 * floatfns.c (in_float):
3113 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3114 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3115 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3116 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3117 * window.c (compare_window_configurations):
3118 Use bool for booleans.
3119 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3120 (Fdefault_file_modes): Now mode_t, not int, for modes.
3121 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3122 (internal_delete_file): Now returns void, not a (boolean) int,
3123 since nobody was looking at the return value.
3124 * lisp.h, window.h: Adjust to above API changes.
3126 * xdisp.c (set_message): Simplify and reindent last change.
3128 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3130 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3132 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3134 * eval.c (call_debugger): Make the function non-static so that we
3135 can call it from set_message.
3137 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3138 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3140 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3142 Give more-useful info on a fatal error (Bug#12328).
3143 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3144 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3145 of doing the work ourselves.
3146 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3147 do most of the work.
3148 (fatal_error_backtrace): New function, taken from the guts
3149 of the old fatal_error_signal, but with a new option to output
3151 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3152 info about the signal than just its number.
3153 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3154 * sysdep.c: Include <execinfo.h>
3155 (emacs_backtrace): New function, taken partly from the previous
3156 code of the 'die' function.
3157 (emacs_abort): Call fatal_error_backtrace rather than abort.
3159 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3161 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3162 eager (load-time) macro-expansion.
3163 * lisp.mk (lisp): Add macroexp.
3165 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3167 Simplify redefinition of 'abort' (Bug#12316).
3168 Do not try to redefine the 'abort' function. Instead, redo
3169 the code so that it calls 'emacs_abort' rather than 'abort'.
3170 This removes the need for the NO_ABORT configure-time macro
3171 and makes it easier to change the abort code to do a backtrace.
3172 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3173 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3174 Remove; sysdep.c's emacs_abort now takes its place.
3175 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3176 'abort' changed to use 'emacs_abort'.
3177 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3178 (abort) [!defined abort]: Rename to ...
3179 (emacs_abort): ... new name.
3180 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3181 the place of the old 'abort' in emacs.c.
3182 * w32.c, w32fns.c (abort): Do not #undef.
3183 * w32.c (emacs_abort): Rename from w32_abort.
3185 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3187 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3188 offsets[j].dv, since the y axis of the screen coordinates points
3189 down, while the y axis of the font definition coordinates points
3190 up. This fixes display of Arabic diacritics such as KASRA and
3191 KASRATAN. (Bug#11860)
3193 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3195 Be more systematic about _setjmp vs setjmp.
3196 * alloc.c (test_setjmp, mark_stack):
3197 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3198 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3199 (png_load, my_error_exit, jpeg_load):
3200 * process.c (send_process_trap, send_process):
3201 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3202 The underscored versions are up to 30x faster on some hosts.
3203 Formerly, the code used setjmp+longjmp sometimes and
3204 _setjmp+_longjmp at other times, with no particular reason to
3205 prefer setjmp+longjmp.
3207 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3209 Fix minor problem found by static checking.
3210 * buffer.c (Fdelete_all_overlays): Return nil.
3212 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3214 * buffer.c (Fdelete_all_overlays): New function.
3216 2012-09-03 Chong Yidong <cyd@gnu.org>
3218 * gtkutil.c: Add extern decl for Qxft.
3220 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3222 * emacs.c, eval.c: Use bool for boolean.
3223 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3224 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3225 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
3226 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
3227 (main, decode_env_path, Fdaemon_initialized):
3228 * eval.c (call_debugger, Finteractive_p, interactive_p):
3229 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
3230 (maybe_call_debugger, Fbacktrace):
3231 * process.c (read_process_output, exec_sentinel):
3232 Use bool for booleans.
3233 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
3234 All callers changed.
3235 * eval.c (interactive_p): Omit always-true boolean argument
3236 EXCLUDE_SUBRS_P. All callers changed.
3237 * dispextern.h, lisp.h: Reflect above API changes.

3242 * msdos.c (fatal_error_in_progress): ... from here.
3243 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead

3246 REDISPLAYING_P when unwinding, instead of saving its previous,
3247 always-false value and then restoring it.
3249 Clean up some extern decls.
3250 Mostly, this hoists extern decls out of .c files and into .h files.
3251 That way, we're more likely to catch errors if the interfaces change.

3337 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3338 more than one grapheme cluster passed to the shaper: compute the
3339 offset adjustment values separately for each cluster. (Bug#11860)
3341 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3342 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3343 about implicit conversions from integer to pointer.
3345 2012-09-01 Daniel Colascione <dancol@dancol.org>
3347 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

3401 window system declarations.
3403 * frame.h: Move common functions here: set_frame_menubar,
3404 x_set_window_size, x_sync, x_get_focus_frame,
3405 x_set_mouse_position, x_set_mouse_pixel_position,
3406 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

3467 * lread.c (init_lread): For out-of-tree builds, only add the
3468 source directory's site-lisp dir to the load-path if it exists,
3469 consistent with in-tree builds. (Bug#12302)
3471 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

3492 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3493 Add window_closed and button_values. Add void as return value for
3494 add(Button|String|Split). addButton takes int instead of Lisp_Object.
3495 Add process_dialog as new member.

3685 (string_escape_byte8):
3686 * charset.c (charset_map_loaded, load_charset_map, read_hex):
3687 (load_charset_map_from_file, map_charset_chars)
3688 (Fdefine_charset_internal, define_charset_internal)
3689 (Fdeclare_equiv_charset, find_charsets_in_text)
3690 (Ffind_charset_region, char_charset, Fiso_charset):
3691 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
3692 (sub_char_table_set, sub_char_table_set_range)
3693 (char_table_set_range, optimize_sub_char_table)
3694 (map_sub_char_table):
3695 Use bool for boolean.
3696 * character.c (str_to_unibyte): Omit last boolean argument; it was
3697 always 0. All callers changed.
3698 * character.h, charset.h: Adjust to match previous changes.
3699 * character.h (char_printable_p): Remove decl of nonexistent function.
3700 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3701 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3702 are all boolean, so make them single-bit bitfields.
3704 * lisp.h (ASET): Remove attempt to detect side effects.
3705 It was meant to be temporary and it often doesn't work,
3706 because when IDX has side effects the behavior of IDX==IDX
3707 is undefined. See Stefan Monnier in
3708 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3710 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3712 * lisp.h (functionp): New function (extracted from Ffunctionp).
3713 (FUNCTIONP): Use it.
3714 * eval.c (Ffunctionp): Use it.
3716 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3718 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3719 as that's faster and simpler than static storage. Don't bother
3720 with the g_main_context_query overhead if g_main_context_pending
3721 says no events are pending.
3722 (gfds, gfds_size): Remove these static vars.
3723 (xgselect_initialize): Remove; no longer needed.
3724 All uses and decls removed.
3726 * emacs.c (fatal_error_signal_hook): Remove.
3727 All uses removed. This leftover from old code was always 0.
3729 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3730 * casefiddle.c (casify_object, casify_region):
3731 * casetab.c (set_case_table):
3732 * category.c, category.h (word_boundary_p):
3733 * category.h (CHAR_HAS_CATEGORY):
3734 Use bool for booleans, instead of int.
3736 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3738 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3740 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3742 On assertion failure, print backtrace if available.
3743 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3744 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3745 * Makefile.in (LIB_EXECINFO): New macro.
3748 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3749 * bytecode.c (exec_byte_code):
3750 * callint.c (check_mark, Fcall_interactively):
3751 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3752 (getenv_internal, sync_process_alive, call_process_exited):
3753 * lisp.h (USE_SAFE_ALLOCA):
3754 Use bool for booleans, instead of int.
3755 * lisp.h, process.h: Adjust prototypes to match above changes.
3756 * callint.c (Fcall_interactively): Don't assume the mark's
3757 offset fits in 'int'.
3759 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3761 * buffer.c, buffer.h: Use bool for boolean.
3762 * buffer.c (reset_buffer_local_variables)
3763 (buffer_lisp_local_variables, Fset_buffer_modified_p)
3764 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
3765 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
3766 (overlay_touches_p, overlay_strings, Foverlay_put)
3767 (report_overlay_modification, call_overlay_mod_hooks):
3768 (mmap_enlarge, mmap_set_vars):
3769 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3770 Use bool for booleans, instead of int.
3771 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3772 since the 1-or-0 return value is always ignored anyway.
3773 (mmap_initialized_p):
3774 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3775 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3777 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3779 * bidi.c: Use bool for boolean.
3780 This is a bit more readable, and makes the text segment of bidi.o
3781 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3782 Presumably it's faster too.
3783 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3785 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3786 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
3787 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
3788 (bidi_explicit_dir_char, bidi_level_of_next_char)
3789 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3790 Use bool for booleans, instead of int.
3791 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3792 (bidi_unshelve_cache): Adjust decls to match code.
3794 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3796 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3799 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3801 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3802 * atimer.h: Include <stdbool.h>.
3804 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3806 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3807 compile time tests instead of run time tests on systems that do
3809 (FRAME_MAC_P): Remove leftover from deleted code.
3810 * frame.c (syms_of_frame): Remove leftover from deleted code.
3812 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3814 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3816 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3818 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3819 Otherwise, the compiler complains about (A?B:C) where B is void
3820 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3821 (fontset_add): Return void, for FONTSET_ADD.
3823 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3825 * alloc.c: Use bool for booleans.
3826 (gc_in_progress, abort_on_gc)
3827 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3828 (dont_register_blocks) [GC_MALLOC_CHECK]:
3829 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3830 (check_string_bytes, make_specified_string, memory_full)
3831 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3832 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3833 (mark_stack, valid_pointer_p, make_pure_string)
3834 (Fgarbage_collect, survives_gc_p, gc_sweep):
3835 Use bool for booleans, instead of int.
3836 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3837 Remove unused local.
3838 * alloc.c (PURE_POINTER_P):
3839 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3840 * editfns.c (Fformat):
3841 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3843 * fns.c (sweep_weak_table):
3844 * lisp.h (suppress_checking, push_message, survives_gc_p)
3845 (make_pure_string, gc_in_progress, abort_on_gc):
3846 * lread.c (readchar, read1):
3847 * print.c (Fprin1_to_string):
3848 * xdisp.c (push_message):
3849 Use bool for booleans affected directly or indirectly by
3852 Make recently-introduced setters macros.
3853 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3854 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3855 (set_fontset_default, set_fontset_fallback): Rename from their
3856 upper-case counterparts, and make them functions rather than macros.
3857 This is more consistent with the other recently-introduced setters.
3858 These don't need to be inline, since they're local.
3860 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3862 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3863 the loop (Bug#12247).
3865 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3867 * lisp.h (vcopy): Use memcpy rather than our own loop.
3868 This fixes a performance regression introduced by the recent
3869 addition of vcopy. This means 'vcopy' will need to be modified
3870 for a copying collector, but that's OK. Also, tighten the
3871 checking in the assertion.
3873 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3875 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3876 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3877 non-base glyph for the width of the base character, according to
3878 what x_draw_composite_glyph_string_foreground expects.
3879 Generate WADJUST value according to composition_gstring_width's
3880 expectations, to produce correct width of the composed character.
3881 Reverse the sign of the DU offset produced by ScriptPlace.
3883 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3885 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3887 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3889 Avoid direct writes to contents member of struct Lisp_Vector.
3890 * lisp.h (vcopy): New function to copy data into vector.
3891 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3892 * fns.c (Ffillarray): Use ASET.
3893 * keyboard.c (timer_check_2): Use AREF and ASET.
3894 (append_tool_bar_item, Frecent_keys): Use vcopy.
3895 * lread.c (read_vector): Use ASET.
3896 * msdos.c (Frecent_doskeys): Use vcopy.
3897 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3898 (Finternal_merge_in_global_face): Use ASET and vcopy.
3899 * xfont.c (xfont_list_pattern): Likewise.
3901 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3903 * window.c (Fwindow_point): For the selected window always return
3904 the position of its buffer's point.
3905 (Fset_window_point): For the selected window always go in its
3906 buffer to the specified position.
3908 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3910 Setter macros for fontsets.
3911 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3912 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3913 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3916 2012-08-20 Glenn Morris <rgm@gnu.org>
3918 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3919 Don't assume that `ln -f' works.
3921 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3923 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3924 and later about non-assignments with no effect. See discussion at
3925 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3928 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3930 Inline setter functions for Lisp_Objects slots of struct specbinding.
3931 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3934 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3936 * window.c (select_window): Always make selected window's buffer
3939 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3941 Use AREF and ASET for docstrings of category tables.
3942 * category.h (CATEGORY_DOCSTRING): Use AREF.
3943 (SET_CATEGORY_DOCSTRING): Use ASET.
3944 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3946 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3948 Inline setter functions for hash table members.
3949 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3950 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3951 (set_hash_key_and_value, set_hash_index, set_hash_next)
3952 (set_hash_hash): New functions.
3953 * charset.c, fns.c: Adjust users.
3955 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3957 Inline getter and setter functions for per-buffer values.
3958 * buffer.h (per_buffer_default, set_per_buffer_default)
3959 (per_buffer_value, set_per_buffer_value): New functions.
3960 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
3961 * buffer.c, data.c: Adjust users.
3963 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3965 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3967 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3969 Rely on <config.h> + <unistd.h> to declare 'environ',
3970 as gnulib does this if the system doesn't.
3971 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3972 Remove declaration. MS-Windows declares it on stdlib.h which is
3973 included by conf_post.h.
3974 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3975 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
3976 * vm-limit.c: Include <unistd.h>, for 'environ'.
3978 * unexaix.c, unexcoff.c: Include "mem-limits.h".
3979 (start_of_data): Remove decl; mem-limits.h provides it.
3981 * xdisp.c (handle_invisible_prop): Make it a bit faster
3982 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3984 2012-08-19 Chong Yidong <cyd@gnu.org>
3986 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
3989 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
3991 * .gdbinit: Use call instead of set when calling a function in the
3994 * data.c (set_internal): Don't use set_blv_found.
3995 (Fkill_local_variable): Likewise.
3997 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
3999 * nsfont.m (ns_ascii_average_width): Ensure the string
4000 ascii_printable is initialized with a null-terminated character
4001 array. Otherwise, it can contain undesired extra characters.
4003 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4005 port new setting code to Sun C 5.8 2005/10/13
4006 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4007 Return void, not Lisp_Object. Otherwise, the compiler
4008 complains about (A?B:C) where B is void and C is Lisp_Object
4009 when compiling CHAR_TABLE_SET, due to the recent change to
4010 the API of sub_char_table_set_contents.
4012 2012-08-18 Chong Yidong <cyd@gnu.org>
4014 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
4015 for the string case (Bug#3874).
4017 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4019 * buffer.h (BSET): Remove (Bug#12215).
4020 Replace all uses with calls to new setter functions.

4089 New setter functions.
4091 * termhooks.h (TSET): Remove (Bug#12215).
4092 Replace all uses with calls to new setter functions.
4093 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4094 (TERMHOOKS_INLINE): New macro.
4095 (tset_charset_list, tset_selection_alist): New setter functions.
4096 * terminal.c (TERMHOOKS_INLINE):
4097 Define to EXTERN_INLINE, so that the corresponding functions
4098 are compiled into code.
4099 (tset_param_alist): New setter function.
4101 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
4103 * keyboard.h (KSET): Remove (Bug#12215).
4104 Replace all uses with calls to new setter functions.

4847 value of EMACSLOADPATH, as it is no longer needed.
4848 (check_windows_init_file): Now external, not static.
4849 Use Vload_path as is, without adding anything, as this function is now
4850 called when Vload_path is already set up.

4854 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

4899 * alloc.c (record_xmalloc): New function.
4900 * lisp.h (record_xmalloc): New decl.
4901 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4902 more like a function. This is because the pointer cast is not
4903 needed. All uses changed.
4904 * print.c (print_string, print_error_message): Avoid length recalc.
4906 Improve fix for macroexp crash with debugging (Bug#12118).
4907 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4908 ARRAY_MARK_FLAG when checking subscripts, because ASET is
4909 not supposed to be invoked from the garbage collector.
4910 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
4911 (gc_aset): New function, which is like ASET but can be
4912 used in the garbage collector.

4941 with addition of handling of symlinks and support for 'lstat'.
4942 If possible, get file's attributes and security information by
4943 handle, not by name. Produce S_IFLNK bit for symlinks, when
4944 called from 'lstat'.
4945 (stat, lstat): New functions, call 'stat_worker'.
4946 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4947 symlinks when the underlying filesystem supports them.
4949 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
4951 Fix macroexp crash on Windows with debugging (Bug#12118).
4952 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4953 checking subscripts; problem introduced with the recent
4954 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4955 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4956 since it's used in non-static inline functions now.
4958 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

5451 arms of an 'if', not using conditional expressions; otherwise GDB
5452 complains about the types in the unevaluated arm when the argument
5453 is an integer literal.
5454 (xgetint): Simplify expression.
5455 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5456 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5457 Zaretskii in <http://bugs.gnu.org/12036#13>.
5458 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5459 needed now that we have gdb_make_enums_visible.
5460 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5461 (enum enum_USE_LSB_TAG):
5462 New enum types, packaging up enums that need to be exported to GDB.
5464 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5466 Utility function to make a list from specified amount of objects.

5480 * xdisp.c (syms_of_xdisp): Likewise.
5481 * xfns.c (syms_of_xfns): Likewise.
5483 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5485 Fast save_excursion_save and save_excursion_restore.
5486 * lisp.h (struct Lisp_Excursion): New data type.
5487 (PVEC_EXCURSION): New pseudovector type.
5488 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
5489 to deal with it. Adjust comments.
5490 (init_marker, attach_marker): New prototype.
5491 (unchain_marker): Adjust prototype.
5492 * marker.c (attach_marker): Change to global.

5500 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
5502 Fix export of symbols to GDB (Bug#12036).
5503 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
5504 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5505 emacs.c, as this is a more-suitable home. Had this been done earlier
5506 the fix for 12036 would have avoided some of the problems noted in
5507 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5508 would have been more obvious.
5509 * emacs.c: Do not include <verify.h>; no longer needed.
5510 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5511 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5512 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5513 Remove; now done in lisp.h.
5514 * lisp.h (PUBLISH_TO_GDB): New macro.
5515 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
5516 (DATA_SEG_BITS): Use it.
5517 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
5518 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5519 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5520 not be usable in #if. This simplifies things.
5522 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5524 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
5526 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
5528 Simplify export of symbols to GDB (Bug#12036).
5529 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5530 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5531 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5532 Adjust to changes in lisp.h and emacs.c, by using
5533 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5534 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5535 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5536 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5537 instead of gdb_valbits.
5538 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5539 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5540 instead of gdb_array_mark_flag.
5541 (xboolvector): Get size from $->size, not $->header.size.
5542 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5543 (xreload, hook-run, hookpost-run): Remove.
5544 * emacs.c: Include <verify.h>.
5545 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5546 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5548 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5549 (gdb_USE_LSB_TAG): New enum constants.
5550 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5551 Also define these as enum constants, so they're visible to GDB.
5552 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5553 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5554 as constants, so they're visible to GDB.
5555 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
5556 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
5557 Now enum constants, not macros, so they're visible to GDB.
5558 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5559 more convenient now. All uses changed.
5560 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5561 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5563 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

5568 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
5570 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5571 add argument, tune behavior, and adjust all callers.
5573 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5575 Use typedef for EMACS_INT, EMACS_UINT.
5576 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5577 than macros. This simplifies debugging in the usual case, since
5578 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5579 and it allows expressions involving EMACS_INT casts.
5580 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5582 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
5584 * nsterm.m (ns_read_socket): Return early if there is a modal

5590 that FOCUS-FRAME can be omitted.
5592 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5594 Adjust buffer text indirection counters at the end of Fkill_buffer.
5595 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5596 buffer is definitely dead. This should really fix an issue reported
5597 by Christoph Scholtes again. (Bug#12007).
5598 (init_buffer_once): Initialize indirection counters of
5599 buffer_defaults and buffer_local_symbols (for sanity and safety).
5601 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5603 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5604 and continuation glyphs on tooltip frames, leave them at zero.
5605 Avoids continued lines in tooltips. (Bug#11832)
5607 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
5609 Simplify copy_overlay.
5610 * buffer.c (copy_overlay): Simplify. Use build_marker.

5632 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5634 Swap buffer text indirection counters in Fbuffer_swap_text.
5635 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5636 This avoids crash reported by Christoph Scholtes at
5637 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5639 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5641 * nsmenu.m (Popdown_data): New struct.
5642 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
5644 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.

5646 and autorelease them. Also autorelease img and matrix (Bug#12005).
5647 (dealloc): Remove (Bug#12005).

5664 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
5666 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
5667 as it's limited by the amount of memory, not by INT_MAX.
5669 2012-07-21 Eli Zaretskii <eliz@gnu.org>
5671 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
5672 in special-event-map. See the discussion at

5731 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
5732 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
5733 Adjust users accordingly.
5734 * font.h (font_open_by_name): Adjust prototype.

5752 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
5753 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
5754 'for_each_per_buffer_object_at'.
5755 All uses changed. It's better to use upper-case for macros that
5756 cannot be implemented as functions, to give the reader a clue
5757 that they're special.
5759 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>

5802 * intervals.c (merge_interval_right, merge_interval_left):
5803 Do not zero out this interval if it is absorbed by its children,
5804 as this interval's total length doesn't change in that case. See
5805 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
5807 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
5809 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
5810 when invoking (make-bool-vector N t) and N is a positive

5813 Remove some struct layout assumptions in bool vectors.
5814 * alloc.c (bool_header_size): New constant.
5815 (header_size, word_size): Move earlier, as they're now used earlier.

5818 padding before the data member of a bool vector.
5819 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
5820 than doing the check by hand with an abort ().
5822 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
5824 * eval.c (Fdefvar): Don't check constants since we only set the var if
5825 it's not yet defined anyway (bug#11904).
5827 * lisp.h (last_undo_boundary): Declare new var.
5828 * keyboard.c (command_loop_1): Set it.
5829 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
5830 were auto-added by the command loop (bug#11774).
5832 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
5834 * w32font.c (Qsymbol): Remove local definition.

6335 * s/gnu.h: Remove file, which is now empty.
6337 * s/gnu.h, s/gnu-linux.h:
6338 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
6340 2012-07-11 John Wiegley <johnw@newartisans.com>
6342 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
6343 function attribute, so we only use it if it exists in the
6346 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
6348 Avoid call to strlen in fast_c_string_match_ignore_case.
6349 * search.c (fast_c_string_match_ignore_case): Change to use
6350 length argument. Adjust users accordingly.
6351 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
6353 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

6370 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
6372 Avoid calls to strlen in font processing functions.
6373 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
6374 (font_open_by_name): Change to use length argument.
6375 Adjust users accordingly.
6376 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
6378 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
6379 Change to return ptrdiff_t.
6380 (xfont_list_pattern, xfont_match): Use length returned by

6392 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
6394 Remove "#define unix" that is no longer needed (Bug#11905).
6395 * s/aix4-2.h (unix): Remove; no longer needed.
6397 EMACS_TIME simplification (Bug#11875).
6398 This replaces macros (which typically do not work in GDB)
6399 with functions, typedefs and enums, making the code easier to debug.
6400 The functional style also makes code easier to read and maintain.
6401 * systime.h: Include <sys/time.h> on all hosts, not just if
6402 WINDOWSNT, since 'struct timeval' is needed in general.
6403 (EMACS_TIME): Now a typedef, not a macro.
6404 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
6406 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

6408 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
6409 (EMACS_TIME_LE): Now functions, not macros.
6410 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
6411 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
6412 which are not functions. All uses rewritten to use:
6413 (make_emacs_time): New function.
6414 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
6415 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
6416 not functions. All uses rewritten to use the following, respectively:
6417 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
6418 (add_emacs_time, sub_emacs_time): New functions.
6419 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
6420 * fileio.c (Fcopy_file):
6421 * xterm.c (XTflash): Get the current time closer to when it's used.
6422 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

6426 Simplify by avoiding confusing use of strncpy etc.
6427 * doc.c (Fsnarf_documentation):
6428 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
6429 * frame.c (Fmake_terminal_frame):
6430 * gtkutil.c (get_utf8_string):
6432 * nsmenu.m (ns_update_menubar):
6433 * regex.c (regerror):
6434 Prefer memcpy to strncpy and strncat when either will do.
6435 * fileio.c (Fsubstitute_in_file_name):
6436 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
6437 (menu_separator_name_p):
6438 * nsmenu.m (ns_update_menubar):
6439 Prefer memcmp to strncmp when either will do.
6440 * nsterm.m: Include <ftoastr.h>.
6442 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6443 Prefer snprintf to strncpy.
6444 * nsterm.m (ns_term_init):
6445 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6446 * nsterm.m (ns_term_init):
6447 Avoid the need for strncpy, by using build_string or
6448 make_unibyte_string directly. Use dtoastr, not snprintf.
6449 * process.c (Fmake_network_process): Diagnose service names that
6450 are too long, rather than silently truncating them or creating
6451 non-null-terminated names.
6452 (Fnetwork_interface_info): Likewise, for interface names.
6453 * sysdep.c (system_process_attributes) [GNU_LINUX]:
6454 Prefer sprintf to strncat.
6455 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
6456 Prefer vsnprintf to vsprintf + strncpy.
6458 2012-07-10 Glenn Morris <rgm@gnu.org>
6460 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
6461 Clarify fallback case.
6463 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6465 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
6466 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
6467 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
6468 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
6469 where argument type is known to be a Lisp_Cons.
6471 2012-07-10 Tom Tromey <tromey@redhat.com>
6473 * bytecode.c (BYTE_CODE_THREADED): New macro.
6474 (BYTE_CODES): New macro. Replaces all old byte-code defines.
6475 (enum byte_code_op): New type.

6479 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6481 Optimize pure C strings initialization.
6482 * lisp.h (make_pure_string): Fix prototype.
6483 (build_pure_c_string): New function, defined as static inline. This
6484 provides a better opportunity to optimize away calls to strlen when
6485 the function is called with compile-time constant argument.
6486 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
6487 argument, adjust users accordingly. Use build_pure_c_string where
6489 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
6490 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
6491 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
6493 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6495 Avoid calls to strlen in miscellaneous functions.
6496 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
6497 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
6498 * lread.c (openp): Likewise.
6500 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6502 Avoid calls to strlen in path processing functions.
6503 * fileio.c (file_name_as_directory): Add comment. Change to add
6504 srclen argument and return the length of result. Adjust users
6506 (directory_file_name): Fix comment. Change to add srclen argument,
6507 swap 1st and 2nd arguments to obey the common convention.
6508 Adjust users accordingly.
6509 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
6511 2012-07-10 Glenn Morris <rgm@gnu.org>
6513 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
6514 Move PENDING_OUTPUT_COUNT definition to configure.
6516 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
6517 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
6518 * s/gnu.h (DATA_START): Move definitions to configure.
6520 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
6521 We include usg5-4-common.h, which defines them both.
6523 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
6524 O_RDONLY already includes it).
6526 Stop ns builds setting the EMACSLOADPATH environment variable.
6527 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6528 Now it does not set EMACSLOADPATH, just returns the load-path string.
6529 * nsterm.h: Update accordingly.
6530 * lread.c [HAVE_NS]: Include nsterm.h.
6531 (init_lread) [HAVE_NS]: Use ns_load_path.
6532 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
6534 2012-07-09 Glenn Morris <rgm@gnu.org>
6536 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
6537 since the included bsd-common.h does so.
6539 Stop ns builds setting the EMACSPATH environment variable.
6540 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
6541 (ns_init_paths): Do not set EMACSPATH.
6542 * nsterm.h (ns_exec_path): Add it.
6543 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
6546 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
6548 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
6550 * process.c (wait_reading_process_output): 'waitchannels' was unset
6551 when read_kbd || !NILP (wait_for_cell); fix this.
6553 Add GCC-style 'const' attribute to functions that can use it.
6554 * character.h (char_resolve_modifier_mask):
6555 * keyboard.h (make_ctrl_char):
6556 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
6557 (init_character_once, next_almost_prime, init_fns, init_image)
6558 (flush_pending_output, init_sound):
6559 * mem-limits.h (start_of_data):
6560 * menu.h (finish_menu_items):
6561 Add ATTRIBUTE_CONST.

6563 Declare the dummy function with ATTRIBUTE_CONST.
6564 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
6565 Add decls with ATTRIBUTE_CONST.
6567 Minor improvements to make_formatted_string.
6568 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
6569 where int is good enough, as vsprintf returns an int.
6570 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
6572 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6574 Use make_formatted_string to avoid double length calculation.
6575 * lisp.h (make_formatted_string): New prototype.
6576 * alloc.c (make_formatted_string): New function.
6577 * buffer.c (Fgenerate_new_buffer_name): Use it.
6578 * dbusbind.c (syms_of_dbusbind): Likewise.

6581 * frame.c (make_terminal_frame, set_term_frame_name)
6582 (x_report_frame_params): Likewise.
6583 * image.c (gs_load): Likewise.
6584 * minibuf.c (get_minibuffer): Likewise.
6585 * msdos.c (dos_set_window_size): Likewise.
6586 * process.c (make_process): Likewise.

6599 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6601 Move marker debugging code under MARKER_DEBUG.
6602 * marker.c (MARKER_DEBUG): Move marker debugging code under
6603 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6604 for bootstrap with --enable-checking (~3x slowdown reported
6605 by Juanma Barranquero <lekktu@gmail.com>).
6606 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6608 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6610 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6611 See <http://bugs.gnu.org/11825#29>.
6613 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6615 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6616 has no font, use the frame's font. (Bug#11813)
6617 (display_line): Add commentary about displaying truncation glyphs
6619 (produce_special_glyphs): Move here from term.c.
6621 * term.c (produce_special_glyphs): Move to xdisp.c.
6623 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6626 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6628 * xdisp.c (display_line): Avoid warning about implicit declaration
6631 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6633 * lisp.h: Remove empty conditional.
6635 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6637 * lread.c (load_path_check): Now static.
6639 Fix some minor --with-ns problems found by static checking.
6640 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6641 (x_set_font) [!HAVE_X_WINDOWS]:
6642 * image.c (xpm_load_image) [HAVE_NS]:
6643 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6644 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6645 Remove unused local.
6646 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6647 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6648 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6649 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6650 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6651 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6652 Fix pointer signedness problem.
6653 * xfaces.c (FRAME_X_FONT_TABLE):
6654 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6656 2012-07-07 Glenn Morris <rgm@gnu.org>
6658 * lread.c (load_path_check): New function, split from init_lread.
6659 (init_lread): Reorganize. Motivation:
6660 If EMACSLOADPATH is set, check/warn about that rather than the
6661 defaults, which we are not going to use. Hence we can remove
6662 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6663 Don't warn if site-lisp directories are missing.
6664 If not installed, start from a blank load-path, since
6665 PATH_LOADSEARCH refers to the eventual installation directories.
6667 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6669 Support truncation and continuation glyphs on GUI frames, when
6670 fringes are disabled. (Bug#11832)
6671 * xdisp.c (init_iterator): Get dimensions of truncation and
6672 continuation glyphs even if on GUI frames.
6673 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6674 or both, are absent.
6675 (start_display, move_it_in_display_line_to): Handle the case of a
6676 GUI frame without a fringe to display continuation or truncation
6678 (insert_left_trunc_glyphs): Support GUI frames: make sure
6679 truncation glyphs overwrite enough glyphs from the current line to
6680 have sufficient space in pixels.
6681 (display_line): Support truncation and continuation glyphs on GUI
6682 frames. If some spare pixels are left on the line after inserting
6683 the truncation glyphs, fill that space with a stretch glyph of a
6684 suitably computed width.
6686 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6687 produce_glyphs, to support GUI sessions.
6689 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6691 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6693 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6695 Do not require float-time's arg to fit in time_t (Bug#11825).
6696 This works better on hosts where time_t is unsigned, and where
6697 float-time is applied to the (negative) difference between two times.
6698 * editfns.c (decode_time_components): Last arg is now double *,
6699 not int *, and means to store all the result as a double, without
6700 worrying about whether the seconds part fits in time_t.
6701 All callers changed.
6702 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6703 All callers changed.
6704 (Ffloat_time): Do not fail merely because the specified time falls
6705 outside of time_t range.
6707 2012-07-07 Glenn Morris <rgm@gnu.org>
6709 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
6710 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

6713 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
6715 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
6716 Update dependencies.
6718 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6720 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6722 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
6723 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
6724 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6725 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6726 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6727 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6729 * xfont.c (compare_font_names): Redo to omit the need for casts.
6731 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6733 * xfns.c (Fx_change_window_property): Doc fix.
6734 * w32fns.c (Fx_change_window_property): Doc fix.
6736 * w32fns.c (Fx_window_property): Accept the same arguments as the
6737 X Windows version. Doc fix.
6738 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6740 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6741 Eli Zaretskii <eliz@gnu.org>
6743 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6744 Windows-specific code from nt/config.nt moved here.
6745 Obsolete settings removed.
6747 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6749 * process.c: Avoid unnecessary calls to gettime.
6750 (wait_reading_process_output): Don't get the time of day
6751 when gobbling data immediately and not waiting, as there's no need
6752 for it in that case. This removes a FIXME.
6754 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6756 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6757 is defined (Bug#11768).
6759 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6761 Fix marker debugging code.
6762 * marker.c (byte_char_debug_check): Do not perform the check
6763 if buffer is not multibyte.
6764 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6765 Call byte_char_debug_check with correct arguments.
6767 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6769 Compile marker debugging code only if ENABLE_CHECKING is defined.
6770 * marker.c (byte_char_debug_check, count_markers):
6771 Use only if ENABLE_CHECKING is defined.
6772 (byte_debug_flag): Remove.
6773 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6774 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
6776 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6778 Avoid code repetition in marker-related functions.
6779 * marker.c (attach_marker): New function.
6780 (Fset_marker, set_marker_restricted, set_marker_both)
6781 (set_marker_restricted_both): Use it.
6782 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6783 Consistently rename charno to charpos.
6784 (marker_position): Add eassert.
6785 (marker_byte_position): Convert to eassert.
6787 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6789 Simplify list operations in unchain_overlay and unchain_marker.
6790 * buffer.c (unchain_overlay): Simplify. Add comment.
6791 * marker.c (unchain_marker): Simplify. Fix comments.
6793 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6795 Introduce fast path for the widely used marker operation.
6796 * alloc.c (build_marker): New function.
6797 * lisp.h (build_marker): New prototype.
6798 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6799 * composite.c (autocmp_chars): Likewise.
6800 * editfns.c (buildmark): Remove.
6801 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6802 (save_restriction_save): Use build_marker.
6803 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6804 * window.c (save_window_save): Likewise.
6806 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

6809 to avoid redundant calls to unchain_overlay.
6810 * buffer.c (drop_overlay): New function.
6811 (delete_all_overlays, Fdelete_overlay): Use it.
6812 * minibuf.c (get_minibuffer): Fix comment.
6814 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6816 Port to OpenBSD 5.1 amd64.
6817 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6818 This is needed for OpenBSD, and should be harmless on all BSD systems.
6819 Also, include <sys/sysctl.h>, as it should be available on all
6820 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6821 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6822 use p_pid member, not kp_proc.pid.
6824 2012-07-06 Glenn Morris <rgm@gnu.org>
6826 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6828 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6830 More xmalloc and related cleanup.
6831 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

6838 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6839 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6841 Omit needless casts involving void * pointers and allocation.
6842 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6843 as the former is more robust if P's type is changed.
6844 Prefer xzalloc to xmalloc + memset 0.
6845 Simplify malloc-or-realloc to realloc.
6846 Don't worry about xmalloc returning a null pointer.
6847 Prefer xstrdup to xmalloc + strcpy.
6848 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6850 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6851 alloca of a constant.
6853 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6855 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6856 hscroll is larger than the line width. Fixes long and futile
6857 looping inside extend_face_to_end_of_line (on a TTY) producing
6858 glyphs that are not needed and thrown away.
6860 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6862 * marker.c (set_marker_restricted_both): Simplify by using
6865 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6867 * editfns.c (region_limit): Simplify by using clip_to_bounds.
6869 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
6871 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
6872 not defined (Bug#11768).
6873 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
6874 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6875 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6876 followed by gtk_box_set_homogeneous (Bug#11768).
6877 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6878 (update_theme_scrollbar_width, xg_create_scroll_bar):
6879 Use gtk_scrollbar_new (Bug#11768).
6880 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6881 (is_box_type): New function (Bug#11768).
6882 (xg_tool_item_stale_p): Call is_box_type.
6883 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6884 with default display (Bug#11768).

6888 * xdisp.c (window_hscroll_limited): New function.
6889 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6890 coordinates when window's hscroll is set to insanely large
6893 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6895 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6896 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6898 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6901 * lisp.h (xzalloc): New prototype. Omit needless casts.
6902 * alloc.c (xzalloc): New function. Omit needless casts.

6954 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6956 * fileio.c (time_error_value): Check the right error number.
6957 Problem reported by Troels Nielsen in
6958 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6960 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6962 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6963 This should be fixed in a better way; see Eli Zaretskii in
6964 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6965 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6967 * fileio.c (time_error_value): Rename from special_mtime.
6968 The old name's problems were noted by Eli Zaretskii in
6969 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6971 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6972 This variable's comment says Emacs needs at least one GDB-visible
6973 symbol of type enum pvec_type, to work around GDB problems.
6974 The symbol's value doesn't matter.
6976 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6977 that causes compilation to fail on pre-C99 compilers.
6979 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6981 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6982 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6984 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6986 * buffer.c (init_buffer_once): Fix initialization of
6987 headers for buffer_defaults and buffer_local_symbols.
6988 Reported by Juanma Barranquero <lekktu@gmail.com>.
6990 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6992 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6993 * lisp.h (enum pvec_type): Use fewer bits.
6994 (PSEUDOVECTOR_SIZE_BITS): New constant.
6995 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
6996 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
6997 change in pvec_type.
6998 (PSEUDOVECTOR_TYPEP): New macro.
6999 (TYPED_PSEUDOVECTORP): Use it.
7000 * fns.c (internal_equal): Adapt code to extract pvectype.

7004 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7005 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7006 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7007 abusing vector->header.next.nbytes.
7008 (live_vector_p): Use PVEC_TYPE.
7009 (mark_object): Adapt code to extract pvectype. Use switch.
7011 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7013 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7014 Tighten new eassert a bit.
7016 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7018 Fix compilation with --enable-gcc-warnings and -O1
7020 * doprnt.c (doprnt): Change type of tem to int, initialize
7021 to avoid compiler warning. Add eassert.
7022 * search.c (simple_search): Initialize match_byte to avoid
7023 compiler warning. Add eassert.
7025 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7027 Avoid weird behavior with large horizontal scrolls.
7028 Without this change, for example, large hscroll values would
7029 mess up Emacs's display on Fedora 15 x86, presumably due to
7030 overflows in int calculations in the display code.
7031 Also, if buffers had long lines, Emacs would freeze.
7032 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7033 (set_window_hscroll): New function, containing the old guts of
7034 Fset_window_hscroll. Return the clipped value.
7035 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7036 This avoids the need to check against PTRDIFF_MAX.
7038 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7040 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7042 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7044 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7046 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7047 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7048 since GCC 4.4.6 issues a bogus warning for them.
7050 Fix bugs in file timestamp newness comparisons.
7051 * fileio.c (Ffile_newer_than_file_p):
7052 * lread.c (Fload): Use full timestamp resolution of files,
7053 not just the 1-second resolution, so that files that are only
7054 slightly newer still count as newer.
7055 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7056 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7058 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7060 * fileio.c: Improve handling of file time marker. (Bug#11852)
7061 (special_mtime): New function.
7062 (Finsert_file_contents, Fverify_visited_file_modtime):
7063 Use it to set special mtime values consistently.
7065 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7067 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7068 marker for non-existing file. (Bug#11852)
7070 2012-07-03 Glenn Morris <rgm@gnu.org>
7072 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7073 and did not make it into globals.h).
7075 2012-07-03 Tom Tromey <tromey@redhat.com>
7077 * window.c (Fset_window_margins, Fset_window_fringes)
7078 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
7079 * textprop.c (Fprevious_property_change): No longer static.
7080 * syntax.c (Fsyntax_table_p): No longer static.
7081 * process.c (Fget_process, Fprocess_datagram_address): No longer

7095 * dired.c (Ffile_attributes): No longer static.
7096 * composite.c (Fcomposition_get_gstring): No longer static.
7097 * callproc.c (Fgetenv_internal): No longer static.
7099 * ccl.h: Remove EXFUNs.
7100 * buffer.h: Remove EXFUNs.
7101 * dispextern.h: Remove EXFUNs.
7102 * intervals.h: Remove EXFUNs.
7103 * fontset.h: Remove EXFUN.
7104 * font.h: Remove EXFUNs.
7105 * dosfns.c (system_process_attributes): Remove EXFUN.
7106 * keymap.h: Remove EXFUNs.
7107 * lisp.h: Remove EXFUNs.
7108 * w32term.h: Remove EXFUNs.
7109 * window.h: Remove EXFUNs.
7110 * xsettings.h: Remove EXFUN.
7111 * xterm.h: Remove EXFUN.
7113 2012-07-03 Glenn Morris <rgm@gnu.org>
7115 * lisp.h (Frandom): Make it visible to C.
7116 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7117 buffer for invisible buffers. (Bug#1229)
7119 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7121 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7122 values which aren't power of 2.
7123 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7124 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7127 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7129 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7131 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7133 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7135 * alloc.c (allocate_vector_block): Remove redundant
7136 calls to mallopt if DOUG_LEA_MALLOC is defined.
7137 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7138 avoid calls to mallopt if zero_vector is returned.
7140 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7142 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7143 is enabled, avoid dereferencing NULL current_sblock if
7146 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7148 Cleanup basic buffer management.
7149 * buffer.h (struct buffer): Change layout to use generic vector
7150 marking code. Fix some comments. Change type of 'clip_changed'
7151 to bitfield. Remove unused #ifndef old.
7152 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7153 (GET_OVERLAYS_AT): Fix indentation.
7154 (for_each_per_buffer_object_at): New macro.
7155 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
7156 (Fbuffer_local_variables): Use it.
7157 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
7158 * alloc.c (allocate_buffer): Adjust to match new layout of
7159 struct buffer. Fix comment.
7160 (mark_overlay): New function.
7161 (mark_buffer): Use it. Use mark_vectorlike to mark normal
7162 Lisp area of struct buffer.
7163 (mark_object): Use it. Adjust marking of misc objects
7164 and related comments.
7166 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7168 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7169 wrapper that is not needed because the wrapped code is a no-op (zero
7170 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7171 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7173 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7175 * alloc.c (mark_buffer): Simplify. Remove prototype.
7176 (mark_object): Add comment. Reorganize marking of vector-like
7177 objects. Use CHECK_LIVE for all vector-like objects except buffers
7178 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7179 Avoid redundant calls to mark_vectorlike for bool vectors.
7181 2012-06-30 Glenn Morris <rgm@gnu.org>
7183 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7185 * epaths.in (PATH_SITELOADSEARCH): New.
7186 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7187 This is rather than relying on --enable-locallisppath elements
7188 having "site-lisp" in their names. (Bug#10208#25, 11658)
7190 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7192 * w32proc.c (sys_select): Accept and ignore one more argument.
7194 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7196 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7197 (pselect) [!MS_DOS]: Redirect to sys_select.
7199 * sysdep.c: Don't include dos.h and dosfns.h.
7201 * process.c (sys_select):
7202 * msdos.c (sys_select): Accept one more argument and ignore it.
7204 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7205 adapt data types and code to that.
7208 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7209 which clashes with the gnulib function of the same name.
7211 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7213 * font.c (font_style_to_value, font_style_symbolic)
7214 (font_prop_validate_style): Add type checks for values in
7217 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7219 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7222 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7224 * xdisp.c (try_window_id): Undo last change.
7226 * w32.c (getwd): Adjust commentary about startup_dir.
7227 (init_environment): Always call sys_access, even in non-MSVC
7228 builds. Don't chdir to the directory of the Emacs executable.
7229 This undoes code from 1997 which was justified by the need to
7230 "avoid conflicts when removing and renaming directories". But its
7231 downside was that every relative file name was being interpreted
7232 relative to the directory of the Emacs executable, which can never
7233 be TRT. In particular, it broke sys_access when called with
7234 relative file names.
7235 (sys_access): Map GetLastError to errno.
7237 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7239 * window.h (struct window): Change type of 'fringes_outside_margins'
7240 to bitfield. Fix comment. Adjust users accordingly.
7241 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
7243 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7246 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
7248 * gnutls.c (emacs_gnutls_handshake):
7249 Add QUIT to make the loop interruptible.
7251 2012-06-29 Glenn Morris <rgm@gnu.org>
7253 * charset.c (init_charset): Make lack of etc/charsets fatal.

7429 Use sprintf return value instead of invoking strlen on result.
7430 In the old days this wasn't portable, since some sprintf
7431 implementations returned char *. But they died out years ago and
7432 Emacs already assumes sprintf returns int.
7433 Similarly for float_to_string.
7434 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

7442 Use sprintf or float_to_string result to avoid need to call strlen.
7443 * data.c (Fnumber_to_string):
7444 Use make_unibyte_string, since the string must be ASCII.
7445 * lisp.h, print.c (float_to_string): Now returns int length.
7446 * term.c (produce_glyphless_glyph):
7447 Use sprintf result rather than recomputing it.
7449 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
7450 * Makefile.in (ALL_CFLAGS):
7451 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

7476 sprintf already null-terminates its output.
7478 * xfns.c (x_window): Remove redundant cast.
7480 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
7482 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
7483 `const char *' to `char *' to avoid compiler warning.
7485 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7487 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7488 instead of truncating it to 63 (admittedly a generous limit).
7490 * process.c: Fix spelling and caps in comments.

7547 * dispnew.c (Fsleep_for, sit_for):
7548 * keyboard.c (kbd_buffer_get_event):
7549 * process.c (Faccept_process_output):
7550 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
7551 This improves on the previous patch, which introduced a bug
7552 when time_t is unsigned and as wide as intmax_t.
7553 See <http://bugs.gnu.org/9000#51>.
7555 2012-06-23 Eli Zaretskii <eliz@gnu.org>

7572 Privately reported by Herbert J. Skuhra.
7573 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

7618 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7620 Support higher-resolution time stamps (Bug#9000).
7621 The time stamps are only nanosecond-resolution at the C level,
7622 since that's the best that any real-world system supports now.
7623 But they are picosecond-resolution at the Lisp level, as that's
7624 easy, and leaves room for future OS improvements.
7626 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7629 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7630 Don't get current time unless it's needed.
7632 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7633 now provides it if it's absent.
7634 (start_atimer): Port to higher-res time stamps.
7635 Check for time stamp overflow. Don't get current time more
7636 often than is needed.
7638 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7639 Include systime.h, not time.h.
7640 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7642 * dired.c: Include stat-time.h.
7643 (Ffile-attributes): File times now have higher resolution.

7646 (struct image): Timestamp now has higher resolution.
7648 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7649 has at least microseconds now. All uses removed.
7650 (update_frame, update_single_window, update_window, update_frame_1)
7651 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7652 (duration_to_sec_usec): Remove; no longer needed.
7654 * editfns.c (time_overflow): Now extern.
7655 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
7656 (float-time, Fformat_time_string, Fcurrent_time_string)

7660 (decode_time_components, lisp_seconds_argument): New functions.
7661 (make_time): Now static.
7662 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7663 Report an error if the time is invalid, rather than having the caller
7666 * fileio.c: Include <stat-time.h>
7667 (Fcopy_file): Copy higher-resolution time stamps.
7668 Prefer to set the time stamp via a file descriptor if that works.
7669 (Fset_file_times, Finsert_file_contents, Fwrite_region)
7670 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7671 (Fvisited_file_modtime, Fset_visited_file_modtime):
7672 Support higher-resolution time stamps.
7674 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7676 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7678 * image.c (prepare_image_for_display, clear_image_cache)
7679 (lookup_image): Port to higer-resolution time stamps.
7681 * keyboard.c (start_polling, bind_polling_period):
7682 Check for time stamp overflow.
7683 (read_char, kbd_buffer_get_event, timer_start_idle)
7684 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7685 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7686 Port to higher-resolution time stamps. Do not assume time_t is signed.
7687 (decode_timer): New function. Timers are now vectors of length 9,
7688 not 8, to accommodate the picosecond component.
7689 (timer_check_2): Use it.
7691 * nsterm.m (select_timeout, timeval_subtract): Remove.
7692 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7693 as they're a bit more accurate and handle overflow better.
7694 (ns_select): Change prototype to be compatible with pselect.
7695 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7696 * nsterm.h (ns_select): Adjust prototype.
7698 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7699 us-resolution time stamps.
7700 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7702 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7704 * lisp.h (time_overflow): New decl.
7705 (wait_reading_process_output): First arg is now intmax_t, not int,
7706 to accommodate larger waits.
7708 * process.h (struct Lisp_Process.read_output_delay):
7709 Now counts nanoseconds, not microseconds.
7710 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7712 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7713 (wait_reading_process_output):
7714 Port to ns-resolution time stamps.
7715 (Faccept_process_output, wait_reading_process_output):
7716 Check for time stamp overflow. Do not assume time_t is signed.
7717 (select_wrapper): Remove; we now use pselect.
7718 (Fprocess_attributes): Now generates ns-resolution time stamps.
7720 * sysdep.c: Include utimens.h. Don't include utime.h
7721 or worry about struct utimbuf; gnulib does that for us now.
7722 (gettimeofday): Remove; gnulib provides a substitute.
7723 (make_timeval): New function.
7724 (set_file_times): Now sets ns-resolution time stamps.
7725 New arg FD; all uses changed.
7726 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7727 (system_process_attributes):
7728 Now returns ns-resolution time stamp. All uses changed.
7729 Check for time stamp overflow.
7731 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7732 provides a substitute now.
7734 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7735 since it guarantees struct timespec.
7736 (EMACS_TIME): Now struct timespec, so that we can support
7737 ns-resolution time stamps.
7738 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7739 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7740 (EMACS_USECS): Remove.
7741 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
7742 so multiply the arg by 1000 before storing it.
7743 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):

7752 (make_timeval, make_lisp_time, decode_time_components): New decls.
7753 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

7848 gets killed during executing of this function (Bug#11665).

8213 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
8215 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
8217 * doprnt.c (doprnt): Truncate multibyte char correctly.
8218 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8219 would mishandle a string argument "Xc" if X was a multibyte
8220 character of length 2: it would truncate after X's first byte
8221 rather than including all of X.
8223 2012-06-06 Chong Yidong <cyd@gnu.org>
8225 * buffer.c (word_wrap): Doc fix.
8227 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
8229 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.
8231 2012-06-03 Glenn Morris <rgm@gnu.org>

8239 binary via PaX flags if the paxctl utility is available.
8240 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8241 Restore PaX flags to their default. (Bug#11398)
8243 2012-06-03 Chong Yidong <cyd@gnu.org>
8245 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
8248 2012-06-03 Chong Yidong <cyd@gnu.org>
8250 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
8251 (note_mode_line_or_margin_highlight): If there is no help echo,
8252 use mode-line-default-help-echo. Handle the case where the mouse
8253 position is past the end of the mode line string.
8255 * buffer.c (buffer_local_value_1): New function, split from
8256 Fbuffer_local_value; can return Qunbound.
8257 (Fbuffer_local_value): Use it.
8258 (Vmode_line_format): Docstring tweaks.
8260 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
8262 * sysdep.c (system_process_attributes): Improve comment.
8264 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
8266 * keyboard.c: Export real-this-command to Elisp.
8267 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
8268 and DEFVAR it. Update all users.
8270 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
8272 * minibuf.c (Fassoc_string): Remove duplicate declaration.
8274 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
8275 Convert pctcpu and pctmem to Lisp float properly.
8276 Let the compiler fold better, as 100.0/0x8000 is exact.
8278 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
8280 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
8283 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
8285 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
8287 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
8289 For a 'struct window', replace some Lisp_Object fields to
8290 bitfields where appropriate, remove unused fields.
8291 * window.h (struct window): Remove unused 'last_mark_x' and
8292 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
8293 change its type from Lisp_Object to bitfield.
8294 Change type of 'force_start', 'optional_new_start',
8295 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8296 fields from Lisp_Object to bitfield. Adjust users accordingly.
8298 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8300 Pacify gcc -Wdouble-precision when using Xaw.
8301 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
8302 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
8303 Use 'float' consistently, rather than 'float' in most places
8304 and 'double' in a couple of places.
8306 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8308 * xdisp.c (handle_stop): Detect whether we have overlay strings
8309 loaded by testing it->current.overlay_string_index to be
8310 non-negative, instead of checking whether n_overlay_strings is
8311 positive. (Bug#11587)
8313 2012-05-31 Chong Yidong <cyd@gnu.org>
8315 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
8317 * doc.c (Fsubstitute_command_keys): Doc fix.
8319 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8321 * search.c (search_buffer): Remove calls to
8322 r_alloc_inhibit_buffer_relocation, as it is now called by
8323 maybe_unify_char, which was the cause of relocation of buffer text
8326 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8328 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8329 for the duration of call to load_charset, to avoid problems with
8330 callers of maybe_unify_char that access buffer text through C
8333 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8334 decrement the inhibition flag, instead of just setting or
8337 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8339 Remove obsolete '#define static' cruft.
8340 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8341 This #undef was "temporary" in 2000; it is no longer needed
8342 now that '#define static' has gone away.
8343 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8344 (gray_bitmap_bits): Remove; no longer needed.
8345 All uses replaced with definiens.
8346 * xterm.c: Include "bitmaps/gray.xbm".
8348 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8350 Clean up __executable_start, monstartup when --enable-profiling.
8351 The following changes affect the code only when profiling.
8352 * dispnew.c (__executable_start): Rename from safe_bcopy.
8353 Define only on platforms that need it.
8354 * emacs.c: Include <sys/gmon.h> when profiling.
8355 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
8356 (__executable_start): Remove decl, since lisp.h does it now.
8357 (safe_bcopy): Remove decl; no longer has that name.
8358 (main): Coalesce #if into single bit of code, for simplicity.
8359 Cast pointers to uintptr_t, since standard libraries want integers
8361 * lisp.h (__executable_start): New decl.
8363 2012-05-31 Glenn Morris <rgm@gnu.org>
8365 * image.c (Fimagemagick_types): Doc fix.
8367 2012-05-30 Jim Meyering <meyering@redhat.com>
8369 * callproc.c (Fcall_process_region): Include directory component
8370 in mkstemp error message (Bug#11586).
8372 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8374 * alloc.c, lisp.h (make_pure_vector): Now static.
8376 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

8379 Move to byte-run.el.
8380 (Fautoload): Do the hash-doc more carefully.
8381 * data.c (Fdefalias): Purify definition, except for keymaps.
8382 (Qdefun): Move from eval.c.
8383 * lisp.h (Qdefun): Remove.
8384 * lread.c (read1): Tiny simplification.
8386 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
8388 Do not create empty overlays with the evaporate property (Bug#9642).
8389 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8390 Bug#9642, but explicitly check that the buffer the overlay would
8391 be moved to is live and rearrange lines to make sure that errors
8392 will not put the overlay in an inconsistent state.
8393 (Fdelete_overlay): Cosmetics.
8395 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8397 * w32term.c (my_bring_window_to_top): New function.
8398 (x_raise_frame): Use handle returned by DeferWindowPos, which
8399 could be different from the original one.
8400 Call my_bring_window_to_top instead of my_set_foreground_window.
8403 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
8404 by calling BringWindowToTop.
8406 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
8407 (WM_EMACS_END): Increase by one.
8409 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
8411 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
8412 This avoids undefined behavior that might cause the eassert
8413 to not catch an out-of-range value.
8415 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8417 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
8418 Update dependencies.
8420 2012-05-27 Eli Zaretskii <eliz@gnu.org>
8422 * bidi.c (bidi_mirror_char): Fix last change.
8424 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
8426 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
8427 when referring to sectname field in printf format.
8429 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
8431 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8432 Only r_alloc_inhibit_buffer_relocation needed to be added;
8433 the others were already declared.
8435 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8436 before checking whether it's out of range. Put the check inside
8438 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8440 2012-05-27 Ken Brown <kbrown@cornell.edu>
8442 * callproc.c (Fcall_process): Restore a line that was accidentally
8443 commented out in the 2011-02-13 change (bug#11547).
8445 2012-05-27 Eli Zaretskii <eliz@gnu.org>
8447 * lisp.h [REL_ALLOC]: Add prototypes for external functions
8448 defined on ralloc.c.
8450 * buffer.c [REL_ALLOC]: Remove prototypes of
8451 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
8452 they are now on lisp.h.
8454 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8456 * search.c (search_buffer): Use it to inhibit relocation of buffer
8457 text while re_search_2 is doing its job, because re_search_2 is
8458 passed C pointers to buffer text. (Bug#11519)
8460 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8463 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8464 state after an additional call to move_it_in_display_line_to, keep
8465 the values of it->max_ascent and it->max_descent found for the
8467 (pos_visible_p): Revert the comparison against bottom_y to what it
8468 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8471 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8473 Fix coding-related core dumps with gcc -ftrapv.
8474 The code was computing A - B, where A and B are pointers, and B is
8475 random garbage. This can lead to core dumps on platforms that
8476 have special pointer registers, and it also leads to core dumps on
8477 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8478 A - B only when B is initialized properly.
8479 * coding.c (coding_set_source, coding_set_destination): Return void.
8480 (coding_change_source, coding_change_destinations): New functions,
8481 with the old behaviors of coding_set_source and coding_set_destination.
8482 All callers that need an offset changed to use these new functions.
8484 2012-05-26 Glenn Morris <rgm@gnu.org>
8486 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
8488 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8490 Extend mouse support on W32 text-mode console.
8491 * xdisp.c (draw_row_with_mouse_face):
8492 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8494 * w32console.c: Include window.h.
8495 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8497 (initialize_w32_display): Initialize mouse-highlight data.
8499 * w32inevt.c: Include termchar.h and window.h.
8500 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8501 moves, call note_mouse_highlight. If help_echo changed, call
8502 gen_help_event to produce help-echo message in the echo area.
8503 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8506 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8508 * lread.c (read1): Simplify slightly to avoid an overflow warning
8509 with GCC 4.7.0 on x86-64.
8511 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8513 * bidi.c (bidi_mirror_char): Revert last change: an int is
8514 definitely wide enough here.
8516 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
8518 Fix integer width and related bugs (Bug#9874).
8519 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
8520 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
8521 (string_bytes, check_sblock, allocate_string_data):
8522 (compact_small_strings, Fmake_bool_vector, make_string)
8523 (make_unibyte_string, make_multibyte_string)
8524 (make_string_from_bytes, make_specified_string)
8525 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
8526 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
8528 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8529 (allocate_pseudovector):
8530 Use int, not EMACS_INT, where int is wide enough.
8531 (inhibit_garbage_collection, Fgarbage_collect):
8532 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8533 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
8534 int might not be wide enough.
8535 (bidi_cache_search, bidi_cache_find, bidi_init_it)
8536 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
8537 (bidi_at_paragraph_end, bidi_find_paragraph_start)
8538 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
8539 (bidi_level_of_next_char, bidi_move_to_visually_next):
8540 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8541 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
8542 (Fkill_buffer, Fset_buffer_major_mode)
8543 (advance_to_char_boundary, Fbuffer_swap_text)
8544 (Fset_buffer_multibyte, overlays_at, overlays_in)
8545 (overlay_touches_p, struct sortvec, record_overlay_string)
8546 (overlay_strings, recenter_overlay_lists)
8547 (adjust_overlays_for_insert, adjust_overlays_for_delete)
8548 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
8549 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
8550 (Foverlay_recenter, last_overlay_modification_hooks_used)
8551 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8552 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8553 (validate_region): Omit unnecessary test for b <= e,
8554 since that's guaranteed by the previous test.
8555 (adjust_overlays_for_delete): Avoid pos + length overflow.
8556 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8557 (report_overlay_modification):
8558 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8559 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
8560 Omit pointer cast, which isn't needed anyway, and doesn't work
8561 after the EMACS_INT -> ptrdiff_t change.
8562 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
8563 * buffer.h: Adjust decls to match defn changes elsewhere.
8564 (struct buffer_text, struct buffer):
8565 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8566 Use EMACS_INT, not int, where int might not be wide enough.
8567 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
8568 not int, to avoid needless 32-bit limit on 64-bit hosts.
8569 (exec_byte_code): Use tighter memory-full test, one that checks
8570 for alloca overflow. Don't compute the address of the object just
8571 before an array, as that's not portable. Use EMACS_INT, not
8572 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8573 * callint.c (Fcall_interactively):
8574 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8575 * callproc.c (call_process_kill, Fcall_process):
8576 Don't assume pid_t fits into an Emacs fixnum.
8577 (call_process_cleanup, Fcall_process, child_setup):
8578 Don't assume pid_t fits into int.
8579 (call_process_cleanup, Fcall_process, delete_temp_file)
8580 (Fcall_process_region):
8581 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8582 (Fcall_process): Simplify handling of volatile integers.
8583 Use int, not EMACS_INT, where int will do.
8584 * casefiddle.c (casify_object, casify_region, operate_on_word)
8585 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
8586 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8587 (casify_object): Avoid integer overflow when overallocating buffer.
8588 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
8589 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
8590 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
8591 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8592 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8593 integers are now checked earlier. All uses replaced with XINT.
8595 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8596 For CCL_MapSingle, check that content and value are in int range.
8597 (ccl_driver, Fregister_code_conversion_map):
8598 Check that Vcode_version_map_vector is a vector.
8599 (resolve_symbol_ccl_program): Check that vector header is in range.
8600 Always copy the vector, so that we can check its contents reliably
8601 now rather than having to recheck each instruction as it's being
8602 executed. Check that vector words fit in 'int'.
8603 (ccl_get_compiled_code, Fregister_ccl_program)
8604 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8605 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
8606 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
8607 contents are in range.
8608 (Fccl_execute_on_string): Check that status is in range.
8609 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8610 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8611 Accept and return EMACS_INT, not int, because callers can pass values
8613 (c_string_width, strwidth, lisp_string_width, chars_in_text)
8614 (multibyte_chars_in_text, parse_str_as_multibyte)
8615 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
8616 (str_as_unibyte, str_to_unibyte, string_count_byte8)
8617 (string_escape_byte8, Fget_byte):
8618 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8619 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
8620 avoid mishandling large integers.
8621 * character.h: Adjust decls to match defn changes elsewhere.
8622 * charset.c (load_charset_map_from_file, find_charsets_in_text)
8623 (Ffind_charset_region):
8624 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8625 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
8626 (load_charset_map_from_vector, Fdefine_charset_internal):
8627 Don't assume fixnum fits in int.
8628 (load_charset_map_from_vector, Fmap_charset_chars):
8629 Remove now-unnecessary CHECK_NATNUMs.
8630 (Fdefine_charset_internal): Check ranges here, more carefully.
8631 Don't rely on undefined behavior with signed left shift overflow.
8632 Don't assume unsigned int fits into fixnum, or that fixnum fits
8633 into unsigned int. Don't require max_code to be a valid fixnum;
8634 that's not true for gb10830 4-byte on a 32-bit host. Allow
8635 invalid_code to be a cons, for the same reason. Require code_offset
8636 to be a character. Avoid int overflow if max_char is close
8638 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8639 this is intended anyway and avoids some undefined behavior.
8640 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8641 INDEX_TO_CODE_POINT, as that's what it expects.
8642 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8643 * charset.h (DECODE_CHAR): Return int, not unsigned;
8644 this is what was intended anyway, and it avoids undefined behavior.
8645 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8646 integer-overflow issues.
8647 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
8648 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
8649 where the argument is EMACS_INT, and this behavior is not intended.
8650 * chartab.c (Fmake_char_table, Fset_char_table_range)

9361 define them any more.
9362 (VAL_MAX): New macro.
9364 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
9365 BITS_PER_EMACS_INT, in #if.
9366 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
9367 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
9368 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
9369 * s/ms-w32.h (DATA_START):
9370 Move here from removed file m/intel386.h.
9371 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
9372 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
9374 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
9376 Assume C89 or later.
9377 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
9378 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
9380 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
9381 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
9382 * textprop.c, tparam.c (NULL): Remove.
9383 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
9384 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
9385 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
9386 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
9387 * xterm.c (input_signal_count): Assume volatile works.
9389 2012-05-21 Ken Brown <kbrown@cornell.edu>
9391 * xgselect.c (xg_select): Fix first argument in call to 'select'
9394 2012-05-20 Ken Brown <kbrown@cornell.edu>
9396 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
9397 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
9399 2012-05-19 Ken Brown <kbrown@cornell.edu>
9401 * xfns.c (x_in_use): Remove `static' qualifier.
9402 * xterm.h (x_in_use): Declare.
9403 * xgselect.c: Include xterm.h.
9404 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
9405 and `display_arg' (bug#9754).
9407 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
9409 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
9411 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
9412 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
9414 2012-05-18 Eli Zaretskii <eliz@gnu.org>
9416 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
9418 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
9419 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
9421 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
9422 reference to image_cache->refcount.
9423 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
9425 2012-05-17 Juri Linkov <juri@jurta.org>
9427 * search.c (Fword_search_regexp, Fword_search_backward)
9428 (Fword_search_forward, Fword_search_backward_lax)
9429 (Fword_search_forward_lax): Move functions to isearch.el
9430 (bug#10145, bug#11381).
9432 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
9434 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
9436 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
9438 * lread.c (init_obarray): Declare Qt and Qnil as special.
9440 2012-05-14 Glenn Morris <rgm@gnu.org>
9442 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9443 Put "libexec" before "bin", for the sake of init_callproc_1.
9445 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9447 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
9449 * unexaix.c: Port to more-recent AIX compilers.
9450 (report_error, report_error_1, make_hdr, copy_sym)
9451 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9452 Make arguments const char *, not char *, to avoid violations of C
9453 standard and to fix some AIX warnings reported by Gilles Pion.
9455 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9457 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9458 already have overlays loaded.
9459 (handle_single_display_spec): Before returning without displaying
9460 fringe bitmap, synchronize the bidi iterator with the main display
9461 iterator, by calling iterate_out_of_display_property.
9462 (iterate_out_of_display_property): Detect buffer iteration by
9463 testing that it->string is a Lisp string.
9464 (get_next_display_element): When the current object is exhausted,
9465 and there's something on it->stack, call set_iterator_to_next to
9466 proceed with what's on the stack, instead of returning zero.
9467 (set_iterator_to_next): If called at the end of a Lisp string,
9468 proceed to consider_string_end without incrementing string
9469 position. Don't increment display vector index past the end of
9470 the display vector. (Bug#11417)
9471 (pos_visible_p): Don't report a position visible when move_it_to
9472 stopped at the last line of window, which happens to be scanned
9473 backwards by the bidi iteration. (Bug#11464)
9475 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9477 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9478 and right-margin display specs even if the spec is invalid or we
9479 are on a TTY, and thus unable to display on the fringes.
9480 That's because the text with the property will not be displayed anyway,
9481 so we need to signal to the caller that this is a "replacing"
9482 display spec. This fixes display when the spec is invalid or we
9485 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9487 * unexaix.c (make_hdr): Fix typo in prototype.
9488 This bug broke the build on AIX. Problem reported by Gilles Pion.
9490 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9492 * keyboard.c (kbd_buffer_get_event): Read special events also in
9493 batch mode. (Bug#11415)
9495 2012-05-12 Glenn Morris <rgm@gnu.org>
9497 * ns.mk: Update for ns_appbindir no longer having trailing "/".
9499 2012-05-12 Eli Zaretskii <eliz@gnu.org>
9501 * lisp.mk (lisp): Add newcomment.elc.
9503 2012-05-12 Glenn Morris <rgm@gnu.org>
9505 * Makefile.in (MKDIR_P): New, set by configure.
9506 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9508 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9510 Remove unused function hourglass_started.
9511 * dispextern.h (hourglass_started):
9512 * w32fns.c (hourglass_started):
9513 * xdisp.c (hourglass_started): Remove.
9515 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
9517 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
9518 Update dependencies.
9520 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9522 * xgselect.c (xg_select): Put maxfds+1 into a var.
9523 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9525 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9527 2012-05-10 Dave Abrahams <dave@boostpro.com>
9529 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9530 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9532 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9534 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9535 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9536 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9537 Initialize xd_registered_buses.
9539 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9541 Untag more efficiently if USE_LSB_TAG.
9542 This is based on a proposal by YAMAMOTO Mitsuharu in
9543 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9544 For an admittedly artificial (nth 8000 longlist) benchmark on
9545 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9546 Emacs's overall text size by 1%.
9547 * lisp.h (XUNTAG): New macro.
9548 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9549 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9550 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9551 * eval.c (Fautoload):
9552 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9553 * frame.h (XFRAME): Use XUNTAG.
9555 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9556 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9557 Remove unportable assumptions about print widths of types like
9559 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9560 intptr_t when converting between pointer and integer, to avoid GCC
9561 warnings about wrong width.
9563 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9565 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9566 stack for each reader_thread, instead of defaulting to 8MB
9567 determined by the linker. This avoids failures in creating
9568 subprocesses on Windows 7, see the discussion in this thread:
9569 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9571 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9573 Fix up display of the *Minibuf-0* buffer in the mini window.
9574 * keyboard.c (read_char): Don't clear the echo area if there's no
9576 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9577 contents of *Minibuf-0*) if there's no message displayed in its stead.
9579 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9581 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9584 2012-05-06 Chong Yidong <cyd@gnu.org>
9586 * lisp.mk (lisp): Update.
9588 2012-05-05 Jim Meyering <meyering@redhat.com>
9590 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9592 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9594 * data.c (PUT_ERROR): New macro.
9595 (syms_of_data): Use it. Add new error type `user-error'.
9596 * undo.c (user_error): New function.
9597 (Fprimitive_undo): Use it.
9598 * print.c (print_error_message): Adjust print style for `user-error'.
9599 * keyboard.c (user_error): New function.
9600 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9602 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9604 Do not limit current-time-string to years 1000..9999.
9605 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9606 (Fcurrent_time_string): Support any year that is supported by the
9607 underlying localtime representation. Don't use asctime, as it
9608 has undefined behavior for years outside the range -999..9999.
9610 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9612 Fix race conditions involving setenv, gmtime, localtime, asctime.
9613 Without this fix, interrupts could mess up code that uses these
9614 nonreentrant functions, since setting TZ invalidates existing
9615 tm_zone or tzname values, and since most of these functions return
9616 pointers to static storage.
9617 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9618 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9619 Grow the critical sections to include not just invoking
9620 localtime/gmtime, but also accessing these functions' results
9621 including their tm_zone values if any, and any related TZ setting.
9622 (format_time_string): Last arg is now struct tm *, not struct tm **,
9623 so that the struct tm is saved in the critical section.
9624 All callers changed. Simplify allocation of initial buffer, partly
9625 motivated by the fact that memory allocation needs to be outside
9626 the critical section.
9628 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9630 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9631 with RESET_INTERVAL.
9633 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9634 Remove duplicated buffer name initialization.
9636 2012-05-02 Jim Meyering <jim@meyering.net>
9638 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9640 * xfns.c (x_window): Use xstrdup (Bug#11375).
9642 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9644 * xdisp.c (pos_visible_p): If already at a newline from the
9645 display string before the 'while' loop, don't walk back the glyphs
9646 from it3.glyph_row. Solves assertion violation when the display
9647 string begins with a newline (egg.el). (Bug#11367)
9649 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9651 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9654 2012-05-01 Glenn Morris <rgm@gnu.org>
9656 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9657 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9658 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9659 All were removed before 23.1.
9661 * dispnew.c: Remove HAVE_LIBNCURSES test;
9662 it is always true on relevant platforms.
9664 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9665 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9667 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9669 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9671 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9672 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9675 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9677 Do not avoid creating empty evaporating overlays (Bug#9642).
9678 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9679 That is, do not delete an evaporating overlay if it becomes
9680 empty after its bounds are adjusted to fit within its buffer.
9681 This fix caused other problems, and I'm reverting it until we get
9682 to the bottom of them.
9684 2012-04-27 Chong Yidong <cyd@gnu.org>
9686 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9688 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9690 * xdisp.c (pos_visible_p): If the window start position is beyond
9691 ZV, start the display from buffer beginning. Prevents assertion
9692 violation in init_iterator when the minibuffer window is scrolled
9695 * window.c (window_scroll_pixel_based): Likewise.
9697 2012-04-27 Chong Yidong <cyd@gnu.org>
9699 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9701 2012-04-27 Glenn Morris <rgm@gnu.org>
9703 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9704 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9706 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9708 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9709 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9711 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9713 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9714 display element, check also the underlying string or buffer
9715 character. (Bug#11341)
9717 * w32menu.c: Include w32heap.h.
9718 (add_menu_item): If the call to AppendMenuW (via
9719 unicode_append_menu) fails, disable Unicode menus only if we are
9720 running on Windows 9X/Me.
9722 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9724 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9725 (xgetint): Add missing shift for LSB tags.
9727 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9729 * keyboard.c (read_char): Don't wipe echo area for select window
9730 events: These might get delayed via `mouse-autoselect-window'
9733 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9735 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9736 manipulation of :loaded-from data.
9738 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9740 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9741 now a cons (bug#11311).
9743 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9745 Do not create empty overlays with the evaporate property (Bug#9642).
9746 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9747 if it becomes empty after its bounds are adjusted to fit within
9748 its buffer. Without this fix, in a nonempty buffer (let ((o
9749 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9750 yields an empty overlay that has the evaporate property, which is
9751 not supposed to happen.
9753 Fix minor GTK3 problems found by static checking.
9754 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9755 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9756 (struct _EmacsFixedClass, emacs_fixed_get_type):
9757 Move decls here from emacsgtkfixed.h, since they needn't be public.
9758 (emacs_fixed_get_type): Now static.
9759 (emacs_fixed_class_init): Omit unused local.
9760 (emacs_fixed_child_type): Remove; unused.

9762 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9763 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
9764 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
9765 (EMACS_FIXED_GET_CLASS): Remove; unused.
9766 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9768 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9769 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9771 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9773 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9774 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9775 (__malloc_size_t, __malloc_ptrdiff_t):
9776 Remove. All uses removed, replaced by the definiens if needed,
9777 since we can assume C89 or better now.
9778 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
9779 (protect_malloc_state, align, get_contiguous_space)
9780 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
9781 (malloc_atfork_handler_child, malloc_enable_thread)

9784 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
9785 (special_realloc, _realloc_internal_nolock, _realloc_internal)
9786 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
9787 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9788 Define using prototypes, not old style.
9789 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9790 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
9791 (align): Don't assume that signed integer overflow wraps around.
9792 Omit unused local var.
9793 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
9794 (_free_internal_nolock, memalign, mallochook, reallochook):
9795 Omit no-longer-needed casts.
9796 (valloc): Use getpagesize, not __getpagesize.
9797 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
9798 (struct hdr): The 'magic' member is now size_t, not unsigned long.
9800 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
9802 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
9804 Move functions from C to Lisp. Make non-blocking method calls
9805 the default. Implement further D-Bus standard interfaces.
9807 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.
9808 (QCdbus_request_name_allow_replacement)
9809 (QCdbus_request_name_replace_existing)
9810 (QCdbus_request_name_do_not_queue)

9855 since the two debugging options are incompatible.
9856 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
9858 (mem_init, mem_insert, mem_insert_fixup):
9859 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
9860 (NEED_MEM_INSERT): Remove; no longer needed.
9862 2012-04-22 Leo Liu <sdl.web@gmail.com>
9864 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
9866 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9868 * sysdep.c [__FreeBSD__]: Minor cleanups.
9869 (list_system_processes, system_process_attributes) [__FreeBSD__]:

9880 * lisp.mk (lisp): Update.
9882 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
9884 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.

9889 * print.c (print_preprocess): Only check print_depth if print-circle
9891 (print_object): Check for cycles even when print-circle is nil and
9892 print-gensym is t, but only check print_depth if print-circle is nil.
9894 2012-04-20 Chong Yidong <cyd@gnu.org>
9896 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9897 set the status to "failed" and ensure that sentinel is run.

9912 farther than the first row after the header line, if any.
9913 Don't consider the header-line row as "partially visible", even if
9914 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
9916 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

9952 New extern decls, to avoid calling undeclared functions.
9953 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9954 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9955 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
9956 (NEED_MEM_INSERT): New macro.
9957 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9958 Remove one incorrect comment and fix another.

9977 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
9979 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

9994 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
9995 * s/netbsd.h, s/sol2-6.h:
9996 Remove definition of GC_MARK_STACK, since the default now works.
9997 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

10023 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
10025 2012-04-11 Daniel Colascione <dancol@dancol.org>
10027 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10028 against is gone. It's better to use vfork now so that when Cygwin
10029 gains a new, working vfork, we use it automatically (bug#10398).
10031 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

10051 * w32.c (w32_delayed_load): Record the full path of the library
10052 being loaded (bug#10424).
10054 2012-04-09 Glenn Morris <rgm@gnu.org>
10056 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

10074 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
10075 attempts per process (connection).
10077 2012-04-09 Chong Yidong <cyd@gnu.org>
10079 * eval.c (Fuser_variable_p, user_variable_p_eh)

10084 * minibuf.c (Fread_variable): Callers changed.
10086 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10088 * xdisp.c (set_cursor_from_row): If the display string appears in
10089 the buffer at position that is closer to point than the position
10090 after the display string, display the cursor on the first glyph of
10091 the display string. Fixes cursor display when a 'display' text
10092 property immediately follows invisible text. (Bug#11094)
10094 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10096 composite.c: use 'double' consistently
10097 * composite.c (get_composition_id): Use 'double' consistently
10098 instead of converting 'float' to 'double' and vice versa; this is
10099 easier to understand and avoids a GCC warning.
10101 2012-04-09 Glenn Morris <rgm@gnu.org>
10103 * Makefile.in: Generate leim-list with bootstrap-emacs, in
10104 preparation for dumping it with emacs. (Bug#4789)

10126 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
10127 (mark_memory): Mark Lisp_Objects only if pointers might hide in

10148 [!WINDOWSNT]: New macros.
10149 (init_libxml2_functions, libxml2_loaded_p): New functions.
10150 (parse_region): Call fn_xmlCheckVersion instead of using the macro
10151 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
10152 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
10153 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10155 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
10156 Call init_libxml2_functions before calling libxml2 functions.
10157 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10159 * emacs.c: Don't include libxml/parser.h.

10165 2012-04-07 Eli Zaretskii <eliz@gnu.org>
10167 * indent.c (Fvertical_motion): If there is a display string at
10168 point, use it.vpos to compute how many lines to backtrack after
10169 move_it_to point. (Bug#11133)
10171 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10173 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10174 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10175 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10176 macros related to unification of CJK characters. For the details,
10177 see the discussion following the message here:
10178 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
10180 2012-04-04 Chong Yidong <cyd@gnu.org>
10182 * keyboard.c (Vdelayed_warnings_list): Doc fix.
10184 2012-04-01 Eli Zaretskii <eliz@gnu.org>
10186 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

10194 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10196 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10197 position we get to after a call to move_it_to fails the
10198 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10199 only if we wind up in a string from display property. (Bug#11063)
10201 * window.c (Fdelete_other_windows_internal): Invalidate the row
10202 and column information about mouse highlight, so that redisplay
10203 restores it after reallocating the glyph matrices. (Bug#7464)
10205 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10206 string comes from a `display' text property, use the buffer
10207 position of that property as if we actually saw that position in
10209 (move_it_by_lines): Remove the assertion that
10210 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10211 violated when there's a before-string at the beginning of a line.
10214 2012-03-30 Eli Zaretskii <eliz@gnu.org>
10216 * xdisp.c (append_space_for_newline): If the default face was

10218 (extend_face_to_end_of_line): Use the remapped default face for
10219 extending the face to the end of the line.
10220 (display_line): Call extend_face_to_end_of_line when the default
10221 face was remapped. (Bug#11068)
10223 2012-03-29 Eli Zaretskii <eliz@gnu.org>

10243 * keyboard.c (Vselection_inhibit_update_commands): New variable.
10244 (command_loop_1): Use it; inhibit selection update for

10254 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10256 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10258 * s/ms-w32.h (tzname): Include time.h before redirecting to

10267 !SYNC_INPUT. (Bug#11080)
10269 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10271 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10272 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10273 when fetching a multibyte character consumes more bytes than
10274 CHAR_BYTES returns, due to unification of CJK characters in
10275 string_char. (Bug#11073)
10277 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10279 * process.c (wait_reading_process_output): Handle pty disconnect

10309 it fit in a valid range (Bug#11003).
10311 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10313 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10314 that is not from display property, accept the row as a "cursor
10315 row" if one of the string's character has a non-nil `cursor'
10316 property. Fixes cursor positioning when there are newlines in
10317 overlay strings, e.g. in icomplete.el. (Bug#11035)
10319 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

10353 2012-03-03 Glenn Morris <rgm@gnu.org>
10355 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10357 2012-03-02 Eli Zaretskii <eliz@gnu.org>

10370 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10372 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10373 push_it before setting up the iterator for the first overlay
10374 string, even if we have an empty string loaded.
10375 (next_overlay_string): If there's an empty string on the iterator
10376 stack, pop the stack. (Bug#10903)
10378 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10380 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10381 Suggested by Stefan Monnier in
10382 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10383 * alloc.c (widen_to_Lisp_Object): New static function.
10384 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10385 and widening them to Lisp_Objects. This would work even if
10386 USE_LSB_TAG is defined and wide integers are used, which might
10387 happen in a future version of Emacs.
10389 2012-02-25 Chong Yidong <cyd@gnu.org>
10391 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

10396 before saving to clipboard manager.
10398 2012-02-24 Chong Yidong <cyd@gnu.org>
10400 * keyboard.c (process_special_events): Handle all X selection
10401 requests in kbd_buffer, not just the next one (Bug#8869).
10403 2012-02-23 Chong Yidong <cyd@gnu.org>
10405 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10406 call when setting menu-bar-lines and tool-bar-lines parameters.
10407 (unwind_create_frame_1): New helper function.

10427 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10428 when computing $valmask.
10430 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10431 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10432 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10433 It's useless in that case, and it can cause problems on hosts
10434 that allocate halves of EMACS_INT values separately.
10435 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10436 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10437 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10438 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10439 it avoids undefined behavior on hosts where shifting right by more
10440 than the word width has undefined behavior.
10442 2012-02-19 Chong Yidong <cyd@gnu.org>
10444 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10445 (Funhandled_file_name_directory, Ffile_name_as_directory)
10446 (Fdirectory_file_name, Fexpand_file_name)
10447 (Fsubstitute_in_file_name): Protect against invalid file handler
10448 return values (Bug#10845).

10464 2012-02-15 Chong Yidong <cyd@gnu.org>
10466 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
10467 marked as special. Also, starting docstrings with * is obsolete.

10482 2012-02-12 Chong Yidong <cyd@gnu.org>
10484 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10485 as that creates a dangerous corner case.
10487 * window.c (Fdelete_window_internal): Invalidate the mouse
10488 highlight (Bug#9904).
10490 2012-02-12 Glenn Morris <rgm@gnu.org>

10496 (Fx_disown_selection_internal, Fx_selection_exists_p)
10497 (Fx_selection_owner_p, Fx_get_selection_internal):
10498 Sync docs and argument specs with the xselect.c versions.
10500 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

10522 * buffer.c (Fbuffer_local_variables)
10523 (buffer_lisp_local_variables): Handle unbound vars correctly;
10524 don't let Qunbound leak into Lisp.
10526 2012-02-07 Glenn Morris <rgm@gnu.org>
10528 * image.c (Fimagemagick_types): Doc fix.
10530 * image.c (imagemagick-render-type): Change it from a lisp object
10531 to an integer. Move the doc here from the lisp manual.

10548 2012-02-04 Eli Zaretskii <eliz@gnu.org>
10550 * w32.c (get_emacs_configuration_options):
10551 Include --enable-checking, if specified, in the return value.

10561 before BEGV. (Bug#10696)
10563 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
10565 Handle overflow when computing char display width (Bug#9496).
10566 * character.c (char_width): Return EMACS_INT, not int.
10567 (char_width, c_string_width): Check for overflow when
10568 computing the width; this is possible now that individual
10569 characters can have unbounded width. Problem introduced
10570 by merge from Emacs 23 on 2012-01-19.

10590 0, do not call append_composite_glyph.
10592 2012-02-02 Kenichi Handa <handa@m17n.org>
10594 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
10596 (x_produce_glyphs): If the component of a composition is a null
10597 string, set it->pixel_width to 1 to avoid zero-width glyph.

10601 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
10602 first 2 arguments are identical. This makes inserting large
10603 output from a subprocess an order of magnitude faster on
10604 MS-Windows, where all sbrk'ed memory is always contiguous.
10606 2012-01-31 Glenn Morris <rgm@gnu.org>
10608 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

10689 2012-01-11 Glenn Morris <rgm@gnu.org>
10691 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
10692 from load-path also when installation-directory is nil. (Bug#10208)

10699 Update template values to be closer to their typical values these days.
10701 2012-01-09 Eli Zaretskii <eliz@gnu.org>
10703 * xdisp.c (rows_from_pos_range): Accept additional argument
10704 DISP_STRING, and accept any glyph in a row whose object is that
10705 string as eligible for mouse highlight. Fixes mouse highlight of
10706 display strings from overlays. (Bug#10464)
10708 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
10710 emacs: fix an auto-save permissions race condition (Bug#10400)
10711 * fileio.c (auto_saving_dir_umask): New static var.
10712 (Fmake_directory_internal): Use it.
10713 (do_auto_save_make_dir): Set it, instead of invoking chmod after
10714 creating the directory. The old code temporarily assigns
10715 too-generous permissions to the directory.
10716 (do_auto_save_eh): Clear it.
10717 (Fdo_auto_save): Catch all errors, not just file errors, so
10718 that the var is always cleared.
10720 2012-01-07 Eli Zaretskii <eliz@gnu.org>
10722 * search.c (scan_buffer): Pass character positions to

10758 * coding.c (Fdefine_coding_system_internal): Make an utf-8 base
10759 coding-system ASCII compatible only when it does not produce BOM

11219 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
11220 Otherwise, valgrind does not work on some platforms.
11221 Problem reported by Andreas Schwab in
11222 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
11223 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
11224 is set, removing the need for VIRT_ADDRESS_VARIES.
11225 (PURE_P): Use a more-efficient implementation that needs just one
11226 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
11227 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
11228 to 4 (xorl, subq, cmpq, setbe).

11232 consistency with the new puresize.h.
11233 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

11323 Fixes assertion violations in row_equal_p. (Bug#10035)
11325 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

11466 Otherwise, these inline functions do not conform to C99 and
11467 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11468 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11469 * intervals.c (adjust_intervals_for_insertion)

11472 (static_offset_intervals): Remove.
11473 (offset_intervals): Rewrite using the old contents of
11474 static_offset_intervals. The old version didn't conform to C99
11475 because an extern inline function contained a reference to an
11476 identifier with static linkage.

11686 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
11688 * window.c (make_window): Initialize phys_cursor_on_p.
11690 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
11692 * lisp.h (struct Lisp_Symbol): Update comments.
11694 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
11696 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
11698 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11700 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
11701 <oslsachem@gmail.com> for helping to debug this.
11703 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
11704 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
11705 (g_b_init_get_glyph_outline_w): New static variables.
11706 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
11707 (GetGlyphOutlineW_Proc): New typedefs.
11708 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
11709 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
11711 (w32font_open_internal, compute_metrics):
11712 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11713 instead of calling the "wide" APIs directly.
11715 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11717 * w32.h (syms_of_w32font): Add prototype.
11719 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11721 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
11722 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
11723 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
11724 (Fmove_to_window_line): Doc fix.
11726 2011-10-27 Chong Yidong <cyd@gnu.org>
11728 * process.c (make_process): Set gnutls_state to NULL.
11730 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11731 non-NULL, regardless of GNUTLS_INITSTAGE.
11732 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
11733 an error. Set process slots as soon as we allocate them.
11735 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
11737 2011-10-27 Chong Yidong <cyd@gnu.org>
11739 * gnutls.c (emacs_gnutls_deinit): New function.
11740 Deallocate credentials structures as well as calling gnutls_deinit.
11741 (Fgnutls_deinit, Fgnutls_boot): Use it.
11743 * process.c (make_process): Initialize GnuTLS credentials to NULL.
11744 (deactivate_process): Call emacs_gnutls_deinit.
11746 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11748 * image.c (x_create_x_image_and_pixmap):
11749 * w32.c (sys_rename, w32_delayed_load):
11750 * w32font.c (fill_in_logfont):
11751 * w32reg.c (x_get_string_resource): Silence compiler warnings.
11753 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
11755 * w32fns.c (w32_default_color_map): New function,
11756 extracted from Fw32_default_color_map.
11757 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
11759 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
11761 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
11763 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
11765 * keyboard.c (test_undefined): New function (bug#9751).
11766 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
11768 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
11770 * sysdep.c (init_sys_modes): Fix the check for the controlling
11771 terminal (Bug#6649).
11773 2011-10-20 Eli Zaretskii <eliz@gnu.org>
11775 * dispextern.h (struct bidi_it): New member next_en_type.
11777 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11778 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11779 current character, check also for next_en_type being WEAK_EN.
11780 (bidi_resolve_weak): Don't enter the expensive loop if the current
11781 position is before next_en_pos. Record the bidi type of the first
11782 non-ET, non-BN character we find, in addition to its position.
11783 (bidi_level_of_next_char): Invalidate next_en_type when
11784 next_en_pos is over-stepped.
11786 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11788 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11789 * editfns.c: Rewrite current-time-zone so that it invokes
11790 the equivalent of (format-time-string "%Z") to get the time zone name.
11791 This fixes a bug when the time zone name contains characters that
11792 need converting from the system time locale to Emacs internal format.
11793 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11794 that patch fixed format-time-string to do the conversion, but
11795 I forgot to fix current-time-zone.
11796 (format_time_string): New function, containing most of
11797 what Fformat_time_string used to contain.
11798 (Fformat_time_string): Rewrite in terms of format_time_string.
11799 This doesn't change this function's behavior.
11800 (current-time-zone): Rewrite to use format_time_string.
11801 This fixes the bug reported by Michael Schierl in
11802 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11803 Jason Rumney's 2007-06-07 change worked around this bug, but
11805 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11807 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11809 * xdisp.c (start_display): If the character at POS is displayed
11810 via a display vector, reset IT->current.dpvec_index to zero.
11811 (try_window_reusing_current_matrix): If a line ends in a display
11812 vector or the next line starts in a display vector, continue
11813 redrawing the window even though the character position of
11814 start_row was reached.
11817 2011-10-18 Chong Yidong <cyd@gnu.org>
11819 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11820 with nobreak-char-display too.
11822 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11824 Fix part 3 of bug#9771.
11825 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11826 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11827 non-neutral characters if the current character is a paragraph
11828 separator (a.k.a. Newline). This avoids running the same
11829 expensive loop twice, once when we consume the preceding newline
11830 and the other time when the line actually needs to be displayed.
11831 Avoid the loop when we see neutrals on the base embedding level
11832 following a character whose directionality is the same as the
11833 paragraph's. This avoids running the expensive loop when a line
11834 ends in a long sequence of neutrals, like control characters.
11835 Add assertion against STRONG_AL type. Slightly rearrange code
11836 that determines the type of a neutral given the first non-neutral
11838 (bidi_level_of_next_char): Set next_en_pos to zero when
11839 invalidating its info.
11841 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11843 * xdisp.c (push_display_prop): Determine whether to record string
11844 or buffer position by IT->string, not by IT->method. Allow
11845 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11846 (move_it_vertically_backward): Don't look for character position
11847 immediately after the newline when in a continuation line.
11850 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11852 * window.c (coordinates_in_window): Rewrite and delabelize
11853 vertical border check. (Bug#5357) (Bug#9618)
11855 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11857 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11858 errors in XSetWindowBorder (bug#9310).
11860 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11862 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11863 avoid crash when xmalloc overrun checking is enabled.
11865 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11867 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11868 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11869 cursor motion with <left> and <right> arrow keys.
11871 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11872 some callers set that themselves.
11874 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11876 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11877 display string and the previous row comes from the same string and
11878 is empty. (Bug#9739) (Bug#9738)
11880 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11882 * doc.c (get_doc_string): Encode file name (bug#9735).
11884 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11886 * bidi.c (bidi_level_of_next_char):
11887 * xdisp.c (get_visually_first_element): Remove old incorrect
11888 comments regarding the Unicode Line Separator character.
11890 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11892 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11894 * alloc.c (Fgc_status): Do not access beyond zombies array
11895 boundary if nzombies > MAX_ZOMBIES.
11896 * alloc.c (dump_zombies): Add missing format specifier.
11898 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11900 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11901 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11903 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11904 Some packages use them to denote characters with modifiers.
11906 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11908 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11909 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11910 matching a pp-number. Rename parameter var to var1.
11912 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11914 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11916 2011-10-08 Glenn Morris <rgm@gnu.org>
11918 * callint.c (Fcall_interactively): Give a more explicit error for the
11919 'c' case with a non-character input. (Bug#8479)
11921 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11923 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11925 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11926 lines that are hscrolled on the left.
11928 * dispnew.c (buffer_posn_from_coords): Account for a possible
11929 presence of header-line. (Bug#4426)
11931 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11933 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11934 Don't advertise functionality which we discourage or doesn't work.
11936 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11938 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11939 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11940 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11941 this makes Emacs dump core during garbage collection on rare
11942 occasions. sizeof is obviously inferior to offsetof here, so
11943 stick with offsetof.
11944 (GC_POINTER_ALIGNMENT): New macro.
11945 (mark_memory): Omit 3rd (offset) arg; caller changed.
11946 Don't assume EMACS_INT alignment is the same as pointer alignment.
11948 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11950 * keyboard.c (read_key_sequence_remapped): New var.
11951 (read_key_sequence): Compute remapping in the right buffer.
11952 (command_loop_1): Use read_key_sequence's remapping directly.
11954 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11956 * dired.c (file_name_completion): Don't expand file name.
11957 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11958 before checking file name handler.
11960 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11961 they've been requested explicitly (bug#9591).
11963 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11965 * keymap.c (Fsingle_key_description): Use make_specified_string
11966 instead of build_string to build string from push_key_description.
11969 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11971 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11972 This fixes a Y2038 bug on 64-bit hosts.
11973 * buffer.c (reset_buffer):
11974 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11975 (Fclear_buffer_auto_save_failure):
11976 Use 0, not -1, to represent an unset failure time, since time_t
11977 might not be signed.
11979 Remove dependency on glibc malloc internals.
11980 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11981 Move back here from lisp.h, but with their new implementations.
11982 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11983 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11984 * charset.c (charset_table_init): New static var.
11985 (syms_of_charset): Use it instead of xmalloc. This removes a
11986 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11987 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11988 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11989 Move back to alloc.c.
11990 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11991 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11993 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
11995 * nsterm.m (windowDidResize): Call x_set_window_size only when
11996 ns_in_resize is true. Otherwise set pixelwidth/height and
11997 call change_frame_size (Bug#9628).
11999 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12001 Port --enable-checking=all to Fedora 14 x86-64.
12002 * charset.c (syms_of_charset): Also account for glibc malloc's
12003 internal overhead when calculating the initial malloc maximum.
12005 Port --enable-checking=all to Fedora 14 x86.
12006 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12008 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12009 (overrun_check_realloc, overrun_check_free):
12010 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12011 That way, xmalloc returns a properly-aligned pointer even if
12012 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12013 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12014 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12015 into account when calculating the initial malloc maximum.
12016 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12017 Move here from alloc.c, so that charset.c can use it too.
12018 Properly align; the old code wasn't right for common 32-bit hosts
12019 when configured with --enable-checking=all.
12020 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12021 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12023 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12025 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12028 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12030 * xdisp.c (compute_display_string_end): If there's no display
12031 string at CHARPOS, return -1.
12033 * bidi.c (bidi_fetch_char): When compute_display_string_end
12034 returns a negative value, treat the character as a normal
12035 character not covered by a display string. (Bug#9624)
12037 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12039 * lread.c (Fread_from_string): Fix typo in docstring.
12041 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12043 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12044 newline, reseat the iterator instead of bidi-iterating there one
12045 character at a time. (Bug#9610)
12046 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12047 TO_CHARPOS if the bidi iterator is at base embedding level.
12049 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12051 * lread.c (readevalloop): Use correct code for NBSP.
12052 (read1): Likewise. (Bug#9608)
12054 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12056 * dbusbind.c (Fdbus_register_signal): When service is not
12057 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12059 2011-09-25 Glenn Morris <rgm@gnu.org>
12061 * buffer.c (truncate-lines): Doc fix.
12063 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12065 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12066 (Fset_window_next_buffers): Doc fix.
12068 2011-09-24 Glenn Morris <rgm@gnu.org>
12070 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12072 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12074 Fix minor problems found by static checking.
12075 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12076 * indent.c (Fvertical_motion): Fix == vs = typo.
12078 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12080 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12081 Default value is now t. Doc fix.
12083 * indent.c (Fvertical_motion): Compute and apply the overshoot
12084 logic when moving up, not only when moving down. Fix the
12085 confusing name and values of the it_overshoot_expected variable;
12086 logic changes accordingly. (Bug#9254) (Bug#9549)
12088 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12089 CHARPOS is covered by a display string which includes newlines.
12090 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12091 is covered by a display string with embedded newlines.
12093 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12095 * dbusbind.c (Fdbus_register_signal): Add match rule to
12096 Vdbus_registered_objects_table. (Bug#9581)
12097 (Fdbus_register_method, Vdbus_registered_objects_table):
12100 2011-09-24 Jim Meyering <meyering@redhat.com>
12102 do not ignore write error for any output size
12103 The previous change was incomplete.
12104 While it makes emacs --batch detect the vast majority of stdout
12105 write failures, errors were still ignored whenever the output size is
12106 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12107 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12108 && echo FAIL: ignored write error
12109 FAIL: ignored write error
12110 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12111 && echo FAIL: ignored write error
12112 FAIL: ignored write error
12113 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12115 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12117 * emacs.c (Fkill_emacs): In noninteractive mode exit
12118 non-successfully if a write error occurred on stdout. (Bug#9574)
12120 2011-09-21 Eli Zaretskii <eliz@gnu.org>
12122 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12125 * dispextern.h (struct it): Update the comment documenting what
12128 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12130 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12131 a display string, extend search for cursor position to end of row.
12132 (find_row_edges): If the row ends in a newline from a display
12133 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12134 Handle the case of a display string with multiple newlines.
12135 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12136 non-empty line. Fixes confusing cursor motion with arrow keys at
12137 the beginning of a line that starts with whitespace.
12139 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12141 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12144 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12146 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12147 boolean (Bug#9154).
12149 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12151 * xdisp.c (display_line): Record maximum and minimum buffer
12152 positions even if no glyphs were produced (e.g., by a zero-width
12153 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12154 buffer positions that will be removed from the glyph row because
12156 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12157 column is beyond frame width: don't subtract 1 "pixel" when
12158 computing width of the stretch.
12159 (reseat_at_next_visible_line_start): Undo the change made on
12160 2011-09-17 that saved paragraph information and restored it after
12161 the call to `reseat'. (Bug#9545)
12163 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12165 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12166 and turn window cursor on if cleared (Bug#9415).
12168 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12170 * search.c (boyer_moore): Take unibyte characters from pattern
12171 literally. (Bug#9458)
12173 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12175 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12177 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12179 Fix minor problem found by static checking.
12180 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12181 initialized, to pacify gcc -Wuninitialized.
12183 * fileio.c: Report proper errno when syscall falls.
12184 (Finsert_file_contents): Save and restore errno,
12185 so that report_file_error outputs the correct diagnostic.
12186 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12188 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12190 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12192 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12194 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12195 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12197 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12199 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12200 about the current paragraph and restore it after the call to reseat.
12202 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12203 (bidi_find_paragraph_start): Search back for paragraph beginning
12204 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12205 (bidi_move_to_visually_next): Only trigger paragraph-related
12206 computations when the last character is a newline or at EOB, not
12207 just any NEUTRAL_B. (Bug#9470)
12209 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12210 truncated lines if point is covered by a display string. (Bug#9524)
12212 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12214 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12215 (cons_to_x_long): New function.
12216 (lisp_data_to_selection_data): Use it. Correct the test for
12217 short-versus-long data; it was negated. Break out of vector
12218 loop, for efficiency, when a long datum is discovered.
12220 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12222 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12224 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12226 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12227 GCC PR/17406) by declaring this function with external scope.
12229 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12231 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12232 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12234 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12236 * editfns.c (Fformat): Correctly handle text properties on "%%".
12238 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12240 * xterm.c (x_draw_composite_glyph_string_foreground):
12241 * w32term.c (x_draw_composite_glyph_string_foreground):
12242 * term.c (encode_terminal_code):
12243 * composite.c (composition_update_it, get_composition_id):
12244 * xdisp.c (get_next_display_element)
12245 (fill_composite_glyph_string): Add comments about special meaning
12246 of TAB characters in a composition.
12248 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12250 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12251 This occurs when processing a multibyte format.
12252 Problem reported by Wolfgang Jenker.
12254 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12256 * xdisp.c (try_cursor_movement): Only check for exact match if
12257 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12259 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12261 Remove unused external symbols.
12262 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12263 * xdisp.c (calc_pixel_width_or_height): Now static.
12264 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12265 * indent.c (check_display_width):
12266 * w32term.c: Fix comment to match code.
12267 * xterm.c, xterm.h (x_catching_errors): Remove.
12269 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12271 * xselect.c: Use signed conversions more consistently (Bug#9498).
12272 (selection_data_to_lisp_data): Assume incoming selection data are
12273 signed integers, not unsigned. This is to be consistent with
12274 outgoing selection data, which was modified to use signed integers
12275 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12276 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12277 expects long, not unsigned long.
12279 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12281 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12282 computation of loop end. Reported by Johan Bockgård
12285 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12287 * frame.c (Fother_visible_frames_p): Function deleted.
12289 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12291 * indent.c (compute_motion): Process display vector front to back
12292 rather than the other way around. (Bug#2496)
12294 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12296 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12298 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12300 * minibuf.c (Fread_from_minibuffer): Doc fix.
12302 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12304 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12305 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12307 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12309 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12310 value for non-existent files.
12312 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12314 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12315 set its "size" to -1. This will set the modtime_size field of
12316 the corresponding buffer to -1, which is what
12317 verify-visited-file-modtime expects for files that do not exist.
12320 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12322 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12324 * lisp.h: ... from here. push_key_description is no longer
12325 defined in keyboard.c, so its declaration should not be in
12326 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12327 logically belongs with push_key_description.
12329 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12331 * buffer.h: Include <sys/types.h> instead of <time.h>.
12332 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12333 Problem reported by Herbert J. Skuhra.
12335 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12337 * xml.c (parse_region): Make the parsing work for
12338 non-comment-starting XML files again (bug#9144).
12340 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12342 * image.c (gif_load): Fix calculation of bottom and right corner.
12345 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12347 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12348 redisplay in small windows.
12350 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12352 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12354 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12356 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12357 Operate on live windows only.
12359 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12361 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12363 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12365 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12366 only under bidi iteration.
12368 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12370 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12372 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12374 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12375 Without this fix, the command to link temacs failed due to an
12376 undefined symbol __builtin_isnan. This is because
12377 /usr/include/iso/math_c99.h #defines isnan(x) to
12378 __builtin_isnan(x), but the bundled gcc, which identifies itself
12379 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12381 * floatfns.c (isnan): #undef, and then #define to a clone of
12383 (Fisnan): Always define, since it's always available now.
12384 (syms_of_floatfns): Always define isnan at the Lisp level.
12386 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12388 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12390 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12392 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12393 The previous code assumed that file offsets (off_t values) fit in
12394 EMACS_INT variables, which is not true on typical 32-bit hosts.
12395 The code messed up by falsely reporting buffer overflow in cases
12396 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12397 when "big" contains more than 2**29 bytes, even though this
12398 inserts just one byte and does not overflow the buffer.
12399 (Finsert_file_contents): Store file offsets as off_t
12400 values, not as EMACS_INT values. Check for overflow when
12401 converting between EMACS_INT and off_t. When checking for
12402 buffer overflow or for overlap, take the offsets into account.
12403 Don't use EMACS_INT for small values where int suffices.
12404 When checking for overlap, fix a typo: ZV was used where
12405 ZV_BYTE was intended.
12406 (Fwrite_region): Don't assume off_t fits into 'long'.
12407 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12409 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12411 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12413 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12415 sprintf-related integer and memory overflow issues (Bug#9412).
12417 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12418 (esprintf, exprintf, evxprintf): New functions.
12419 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12420 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12421 (modify_event_symbol): Do not assume that the length of
12422 name_alist_or_stem is safe to alloca and fits in int.
12423 (Fexecute_extended_command): Likewise for function name and binding.
12424 (Frecursion_depth): Wrap around reliably on integer overflow.
12425 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12426 since some callers pass EMACS_INT values.
12427 (Fsingle_key_description): Don't crash if symbol name contains more
12428 than MAX_ALLOCA bytes.
12429 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12430 (get_minibuffer): Arg is now EMACS_INT, not int.
12431 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12432 (esprintf, exprintf, evxprintf): New decls.
12433 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12435 * dbusbind.c (signature_cat): New function.
12436 (xd_signature, Fdbus_register_signal):
12437 Do not overrun buffer; instead, report string overflow.
12439 * dispnew.c (add_window_display_history): Don't overrun buffer.
12440 Truncate instead; this is OK since it's just a log.
12442 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12443 even if the time zone offset is outlandishly large.
12444 Don't mishandle offset == INT_MIN.
12446 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12447 when creating daemon; the previous buffer-overflow check was incorrect.
12449 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12450 which has the guts of the old verror function.
12452 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12453 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12455 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12456 (font_unparse_xlfd): Don't blindly alloca long strings.
12457 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12458 fits in int, when using sprintf. Use single snprintf to count
12459 length of string rather than counting it via multiple sprintfs;
12460 that's simpler and more reliable.
12461 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12462 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12463 sprintf, in case result does not fit in int.
12465 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12466 (fontset_from_font): Print it.
12468 * frame.c (tty_frame_count): Now printmax_t, not int.
12469 (make_terminal_frame, set_term_frame_name): Print it.
12470 (x_report_frame_params): In X, window IDs are unsigned long,
12471 not signed long, so print them as unsigned.
12472 (validate_x_resource_name): Check for implausibly long names,
12473 and don't assume name length fits in 'int'.
12474 (x_get_resource_string): Don't blindly alloca invocation name;
12475 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12478 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12479 (xg_check_special_colors, xg_set_geometry):
12480 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12482 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12483 Use esprintf, not sprintf, in case result does not fit in int.
12485 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12486 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12487 it as a large positive number.
12488 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12489 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12491 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12492 in case result does not fit in int.
12494 * print.c (float_to_string): Detect width overflow more reliably.
12495 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12496 buffer overrun. Don't assume list length fits in 'int'. Treat
12497 print length of 0 as 0, not as infinity; to be consistent with other
12498 uses of print length in this function. Don't overflow print length
12499 index. Don't assume hash table size fits in 'long', or that
12500 vectorlike size fits in 'unsigned long'.
12502 * process.c (make_process): Use printmax_t, not int, to format
12503 process-name gensyms.
12505 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12507 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12508 to avoid potential buffer overrun.
12510 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12511 if X resource line is longer than 512 bytes.
12513 * xfns.c (x_window): Make sprintf buffer a bit bigger
12514 to avoid potential buffer overrun.
12516 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12518 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12520 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12522 Integer overflow fixes for scrolling, etc.
12523 Without these, Emacs silently mishandles large integers sometimes.
12524 For example, "C-u 4294967297 M-x recenter" was treated as if
12525 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12527 * xdisp.c (try_window_id): Check Emacs fixnum range before
12528 converting to 'int'.
12530 * window.c (window_scroll_line_based, Frecenter):
12531 Check that an Emacs fixnum is in range before assigning it to 'int'.
12532 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12533 values converted from Emacs fixnums.
12534 (Frecenter): Don't wrap around a line count if it is out of 'int'
12535 range; instead, treat it as an extreme value.
12536 (Fset_window_configuration, compare_window_configurations):
12537 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12539 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12540 that can exceed INT_MAX. Check that EMACS_INT value is in range
12541 before assigning it to the (possibly-narrower) index.
12542 (match_limit): Don't assume that a fixnum can fit in 'int'.
12544 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12547 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12548 (Fvertical_motion): Don't wrap around LINES values that don't fit
12549 in 'int'. Instead, treat them as extreme values. This is good
12550 enough for windows, which can't have more than INT_MAX lines anyway.
12552 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12554 * Require libxml/parser.h to avoid compilation warning.
12556 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12558 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12559 since this reportedly can destroy thread storage.
12561 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12563 * syntax.c (find_defun_start): Update all cache variables if
12564 exiting early (Bug#9401).
12566 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12568 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12570 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12571 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12572 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12574 * term.c (tty_append_glyph): New function.
12575 (produce_stretch_glyph): Static function and its prototype deleted.
12577 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
12580 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
12582 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12583 when checking :margin (Bug#9390).
12584 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12585 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12586 so that the name doesn't mislead. All uses changed.
12588 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12590 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after

12598 the first character in the line after the newline.
12600 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12602 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12603 (ccl_driver): Do not generate an out-of-range pointer.
12604 (Fccl_execute_on_string): Remove unnecessary check for
12605 integer overflow, noted by Stefan Monnier in
12606 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12607 Remove a FIXME that didn't need fixing.
12608 Simplify the newly-introduced buffer reallocation code.
12610 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12612 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12614 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12616 Integer and memory overflow issues (Bug#9196).
12618 * doc.c (get_doc_string): Rework so that
12619 get_doc_string_buffer_size is the actual buffer size, rather than
12620 being 1 less than the actual buffer size; this makes xpalloc more
12623 * image.c (x_allocate_bitmap_record, cache_image):
12624 * xselect.c (Fx_register_dnd_atom):
12625 Simplify previous changes by using xpalloc.
12627 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12628 since either will do and ptrdiff_t is convenient with xpalloc.

12631 (struct charset_sort_data.priority): Now ptrdiff_t.
12632 (charset_compare): Don't overflow if priorities differ greatly.
12633 (Fsort_charsets): Don't assume list length fits in int.
12634 Check for size-calculation overflow when allocating sort data.
12635 (syms_of_charset): Allocate an initial charset table that is
12636 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12638 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12640 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12641 The actual value is always <= INT_MAX, and leaving it unsigned made
12642 overflow checking harder.
12644 * dispextern.h (struct glyph_matrix.rows_allocated)
12645 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12646 with xpalloc. The values are still always <= INT_MAX.
12648 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12650 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12651 (SAFE_NALLOCA): New macro.

12654 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12655 (set_cache_region, invalidate_region_cache)
12656 (revalidate_region_cache, know_region_cache, region_cache_forward)
12657 (region_cache_backward, pp_cache):
12658 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12659 so that ptrdiff_t * can be passed to xpalloc.
12660 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12661 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

12663 * region-cache.h: Adjust extern decls to match.

12669 (xnmalloc, xnrealloc, xpalloc): New functions.
12671 * bidi.c (bidi_shelve_header_size): New constant.
12672 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12673 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12675 * bidi.c (bidi_cache_shrink):
12676 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12678 Don't update size of array until after memory allocation succeeds,
12679 because xmalloc/xrealloc may not return.
12680 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12681 now that we have proper integer overflow checking.
12682 (record_overlay_string, overlay_strings): Catch overflows when
12683 calculating size of overlay_str_buf.
12685 * callproc.c (Fcall_process): Check for size overflow when
12686 calculating size of args2.
12687 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12688 Normally we prefer signed values, but sticking with ptrdiff_t would
12689 require adding more-complicated checks.
12691 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12692 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12693 Redo buffer-overflow calculations to avoid integer overflow.
12694 Add a FIXME comment where memory seems to be over-allocated.
12696 * character.c (Fstring): Check for size-calculation overflow.
12698 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12699 unnecessary integer overflow. Check for size overflow.
12700 (encode_coding_object): Don't update size until xmalloc succeeds.
12702 * composite.c (get_composition_id): Check for overflow in glyph
12703 length calculations.
12705 Integer and memory overflow fixes for display code.
12706 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12707 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)

12722 Don't update size until allocation succeeds.
12723 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not

12729 (message_length): Now ptrdiff_t, not int.

12731 Don't assume message length fits in int.
12732 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12734 * emacs.c (main): Do not reallocate argv, since there is a null at
12735 the end that can be overwritten, and this way there's no need to
12736 worry about size-calculation overflow.
12737 (sort_args): Check for size-calculation overflow.
12739 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12741 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12743 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12744 (x_set_scroll_bar_width, x_figure_window_size):
12745 Check for integer overflow.
12746 (x_set_alpha): Do not assume XINT fits in int.
12748 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12749 This is for the members text_lines, text_cols, total_lines, total_cols,
12750 where the system imposes an 'int' limit.
12752 * fringe.c (Fdefine_fringe_bitmap):
12753 Don't update size until alloc works.
12755 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12756 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12758 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12759 Check for size-calculation overflow.
12760 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12761 do, as we prefer signed integers.
12762 (id_to_widget.max_size, id_to_widget.used)
12763 (xg_store_widget_in_map, xg_remove_widget_from_map)
12764 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12765 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12766 Use and return ptrdiff_t, not int.
12767 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12768 * gtkutil.h: Change prototypes to match the above.
12770 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12771 are duplicate now that they've been promoted to lisp.h.
12772 (x_allocate_bitmap_record, x_alloc_image_color)
12773 (make_image_cache, cache_image, xpm_load):

12787 calculations. Don't update size until allocation succeeds.
12788 Redo calculations to avoid overflow.

12817 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12818 for command line length. Do not attempt to address one before the
12819 beginning of an array, as that's not portable.
12821 * term.c (max_frame_lines): Remove; unused.
12822 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12824 (encode_terminal_code, calculate_costs): Check for size

12849 Check for size calculation overflow.
12850 (cache_face): Treat size calculation overflows as if they were

12854 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12855 sizes, since they can exceed INT_MAX in size. Check for size

12860 Don't update size until alloc done.
12862 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12863 as sprintf is limited to int lengths.
12865 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12866 (X_LONG_MIN): New macros.
12867 Use them to make the following changes clearer.
12868 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12869 This change doesn't affect the value now, but it may help remind
12870 future maintainers not to raise the value too much later.
12871 (SELECTION_QUANTUM): Remove, replacing with ...
12872 (selection_quantum): ... new function, which avoids overflow.
12874 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12875 assumption that selection length fits in 'int'.

12892 Don't store size until memory allocation succeeds.
12893 (x_get_window_property): Plug memory leak on memory exhaustion.
12894 Don't double-block input; malloc is safe here. Don't assume 2**34
12895 - 4 fits in unsigned long. Add an xassert to check
12896 XGetWindowProperty overflow. Be more careful about overflow
12897 calculations, and distinguish size from memory overflow better.

12899 unsigned int is less than INT_MAX.
12900 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

12902 (lisp_data_to_selection_data): Don't assume that integers
12903 in the range -65535 through -1 fit in an X unsigned short.
12904 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12905 result parameters unless successful. Rely on cons_to_unsigned
12906 to report problems with elements; the old code wasn't right anyway.
12907 (x_check_property_data): Check for int overflow; we cannot use
12908 a wider type due to X limits.
12909 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

12941 * lisp.h (hash_lookup, hash_put):
12942 * minibuf.c (Ftest_completion):
12943 Use ptrdiff_t for hash table indexes, not int (which is too
12944 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12945 32-bit --with-wide-int hosts).
12947 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12948 Add a FIXME comment about memory leaks.

12956 with outlandish widths.
12957 * character.h (sanitize_tab_width): Rename from sanitize_width,
12958 now that we have two such functions. All uses changed.

12983 (make_lispy_movement): Use same integer type in forward decl
12984 that is used in the definition.

12986 Change bufsize argument back to int, undoing my 2011-03-30 change.
12987 We prefer signed types, and int is wide enough here.
12988 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12989 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12990 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12991 length, not size_t. Use ptrdiff_t for index, not int.
12992 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12993 possibility of integer overflow.

13021 Prefer int to unsigned where either will do.
13022 (tiff_handler): New function, combining the cores of the
13023 old tiff_error_handler and tiff_warning_handler.
13024 This function is rewritten to use vsnprintf and thereby avoid
13025 stack buffer overflows. It uses only the features of vsnprintf
13026 that are common to both POSIX and native Microsoft.
13027 (tiff_error_handler, tiff_warning_handler): Use it.
13028 (tiff_load, gif_load, imagemagick_load_image):
13029 Don't assume :index value fits in 'int'.
13030 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
13031 (imagemagick_load_image): Check that crop parameters fit into
13032 the integer types that MagickCropImage accepts. Don't assume
13033 Vimagemagick_render_type has a nonnegative value. Don't assume
13034 size_t fits in 'long'.
13035 (gs_load): Use printmax_t to print the widest integers possible.
13036 Check for integer overflow when computing image height and width.

13049 (handle_single_display_spec): If the display spec is of the form
13050 `(space ...)', and specifies display in the text area, return 2
13052 (try_cursor_movement): Check for the need to scroll more
13053 accurately, and prefer exact match for point under bidi.
13054 Don't advance `row' beyond the last row of the window.

13075 positioning on the newline at EOL of R2L text within L2R
13076 paragraph, and vice versa.
13077 (try_cursor_movement): Check continued rows, in addition to
13078 continuation rows. Fixes unwarranted scroll when point enters a
13079 continued line of R2L text within an L2R paragraph, or vice versa.
13080 (cursor_row_p): Consider the case of point being equal to
13081 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13082 from the end of a short line to the beginning of a continued line
13083 of R2L text within L2R paragraph.

13107 * xdisp.c (redisplay_window): When computing centering_position,
13108 account for the height of the header line. (Bug#8874)
13110 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13111 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13112 candidate is selected by the mouse, and that candidate has a
13113 composed character under the mouse.
13115 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13116 coordinates reported by pos-visible-in-window-p for a composed
13117 character in column zero.

13126 consider it a hit if to_charpos is anywhere in the range of the
13127 composed buffer positions.
13129 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13131 * image.c (gif_load): Don't assume that each subimage has the same
13132 dimensions as the base image. Handle disposal method that is
13133 "undefined" by the gif spec (Bug#9335).
13135 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13137 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

13143 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13144 from an Org mode buffer to a Speedbar frame.
13146 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13147 a composition, take its buffer position from IT->cmp_it.charpos.
13148 Fixes cursor positioning at the beginning of a line that begins
13149 with a composed character.
13151 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13153 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13154 character bidirectional type, use STRONG_L instead. Fixes crashes
13155 in a buffer produced by `describe-categories'.
13157 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13158 members before the level stack, so they would be saved and
13159 restored when copying iterator state. Fixes incorrect reordering
13160 around TABs covered by display properties.
13162 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

13278 (Fnetwork_interface_list): Allocate in increments of bytes instead
13279 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13280 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct

13294 entry. Force push_it to save on the stack the current
13295 buffer/string position, to be restored by pop_it. Fix flags in
13296 the iterator structure wrt the object coming from a display
13297 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13298 properties. (Bug#9284)

13487 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13489 * nsterm.h (nsfont_info): Remove voffset field.
13491 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13493 Implement strike-through and overline on NextStep (Bug#8863).
13495 * nsfont.m (nsfont_open): Use underline position provided by font,
13496 instead of hard-coded value of 2.
13497 (nsfont_draw): Call ns_draw_text_decoration instead.
13499 * nsterm.h: Add declaration for ns_draw_text_decoration.
13501 * nsterm.m (ns_draw_text_decoration): New function for drawing
13502 underline, overline, and strike-through.
13503 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13504 ns_draw_text_decoration. Change treatment of cursor drawing to
13505 accommodate underlining, etc.
13507 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13509 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13512 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13514 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13515 Without this fix, if a signal arrives just after memory fills up,
13516 'malloc' might be invoked reentrantly.
13518 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13519 In other words, assume that every image size is allowed, on non-X
13520 hosts. This assumption is probably wrong, but it lets Emacs compile.
13522 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13524 * regex.c (re_iswctype): Convert return values to boolean.
13526 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13528 * xdisp.c (compute_display_string_pos): Don't use cached display
13529 string position if the buffer had its restriction changed.
13532 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13534 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13536 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13538 Integer signedness and overflow and related fixes. (Bug#9079)
13540 * bidi.c: Integer size and overflow fixes.
13541 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13542 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13543 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13544 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13545 (bidi_find_other_level_edge):
13546 Use ptrdiff_t instead of EMACS_INT where either will do.
13547 This works better on 32-bit hosts configured --with-wide-int.
13548 (bidi_cache_ensure_space): Check for size-calculation overflow.
13549 Use % rather than repeated addition, for better worst-case speed.
13550 Don't set bidi_cache_size until after xrealloc returns, because it
13552 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13553 (bidi_cache_ensure_space): Also check that the bidi cache size
13554 does not exceed that of the largest Lisp string or buffer. See Eli
13555 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13557 * alloc.c (__malloc_size_t): Remove.
13558 All uses replaced by size_t. See Andreas Schwab's note
13559 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13561 * image.c: Improve checking for integer overflow.
13562 (check_image_size): Assume that f is nonnull, since
13563 it is always nonnull in practice. This is one less thing to
13564 worry about when checking for integer overflow later.
13565 (x_check_image_size): New function, which checks for integer
13566 overflow issues inside X.
13567 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13568 This removes the need for a memory_full check.
13569 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13570 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13571 (xbm_read_bitmap_data): Change locals back to 'int', since
13572 their values must fit in 'int'.
13573 (xpm_load_image, png_load, tiff_load):
13574 Invoke x_create_x_image_and_pixmap earlier,
13575 to avoid much needless work if the image is too large.
13576 (tiff_load): Treat overly large images as if
13577 x_create_x_image_and_pixmap failed, not as malloc failures.
13578 (gs_load): Use x_check_image_size.
13580 * gtkutil.c: Omit integer casts.
13581 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13582 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13584 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13586 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13587 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13588 would wrongly return t on a 64-bit host.
13590 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13591 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13592 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13593 and therefore cause GCC to emit a bogus diagnostic in some cases.
13595 * image.c: Integer signedness and overflow and related fixes.
13596 This is not an exhaustive set of fixes, but it's time to
13597 record what I've got.
13598 (lookup_pixel_color, check_image_size): Remove redundant decls.
13599 (check_image_size): Don't assume that arbitrary EMACS_INT values
13600 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13601 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13602 (tiff_load, imagemagick_load_image):
13603 Check for overflow in size calculations.
13604 (x_create_x_image_and_pixmap): Remove unnecessary test for
13605 xmalloc returning NULL; that can't happen.
13606 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13607 (xpm_color_bucket): Use better integer hashing function.
13608 (xpm_cache_color): Don't possibly over-allocate memory.
13609 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13610 (gif_memory_source):
13611 Use ptrdiff_t, not int or size_t, to record sizes.
13612 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13613 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13614 either works, as we prefer signed integers.
13615 (tiff_read_from_memory, tiff_write_from_memory):
13616 Return tsize_t, not size_t, since that's what the TIFF API wants.
13617 (tiff_read_from_memory): Don't fail simply because the read would
13618 go past EOF; instead, return a short read.
13619 (tiff_load): Omit no-longer-needed casts.
13620 (Fimagemagick_types): Don't assume size fits into 'int'.
13622 Improve hashing quality when configured --with-wide-int.
13623 * fns.c (hash_string): New function, taken from sxhash_string.
13624 Do not discard information about ASCII character case; this
13625 discarding is no longer needed.
13626 (sxhash-string): Use it. Change sig to match it. Caller changed.
13627 * lisp.h: Declare it.
13628 * lread.c (hash_string): Remove, since we now use fns.c's version.
13629 The fns.c version returns a wider integer if --with-wide-int is
13630 specified, so this should help the quality of the hashing a bit.
13632 * emacs.c: Integer overflow minor fix.
13633 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13634 Define only if GNU_LINUX.
13635 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13637 * dispnew.c: Integer signedness and overflow fixes.
13638 Remove unnecessary forward decls, that were a maintenance hassle.
13639 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13641 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13642 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13643 (prepare_desired_row, line_draw_cost):
13644 Use int, not unsigned, where either works.
13645 (save_current_matrix, restore_current_matrix):
13646 Use ptrdiff_t, not size_t, where either works.
13647 (init_display): Check for overflow more accurately, and without
13648 relying on undefined behavior.
13650 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13651 Remove, replacing with the new symbols in lisp.h. All uses changed.
13652 * fileio.c (make_temp_name):
13653 * filelock.c (lock_file_1, lock_file):
13654 * xdisp.c (message_dolog):
13655 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13656 Use pMd etc. instead.
13657 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13658 replacing the pWIDE etc. symbols removed from editfns.c.
13660 * keyboard.h (num_input_events): Now uintmax_t.
13661 This is (very slightly) less likely to mess up due to wraparound.
13664 * buffer.c: Integer signedness fixes.
13665 (alloc_buffer_text, enlarge_buffer_text):
13666 Use ptrdiff_t rather than size_t when either will do, as we prefer
13669 * alloc.c: Integer signedness and overflow fixes.
13670 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13671 (__malloc_size_t): Default to size_t, not to int.
13672 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13673 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13674 Prefer ptrdiff_t to size_t when either would do, as we prefer
13676 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13677 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13678 Now const. Initialize with values that are in range even if char
13680 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13681 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13682 These functions do the right thing with sizes > 2**32.
13683 (check_depth): Now ptrdiff_t, not int.
13684 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13685 Adjust to new way of storing sizes. Check for size overflow bugs
13687 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13688 slightly wrong anyway, as it missed one instance of
13689 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13690 (refill_memory_reserve): Omit needless cast to size_t.
13691 (mark_object_loop_halt): Mark as externally visible.
13693 * xselect.c: Integer signedness and overflow fixes.
13694 (Fx_register_dnd_atom, x_handle_dnd_message):
13695 Use ptrdiff_t, not size_t, since we prefer signed.
13696 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13697 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13698 x_dnd_atoms_size and x_dnd_atoms_length.
13700 * doprnt.c: Prefer signed to unsigned when either works.
13702 * doprnt.c (doprnt):
13704 * xdisp.c (vmessage):
13705 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13706 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13707 prefer signed arithmetic to avoid comparison confusion.
13708 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13709 but is a bit tricky.
13711 Assume freestanding C89 headers, string.h, stdlib.h.
13712 * data.c, doprnt.c, floatfns.c, print.c:
13713 Include float.h unconditionally.
13714 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13715 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13716 * regex.c: Likewise for stddef.h, string.h.
13717 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13718 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13719 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13720 (STDC_HEADERS): Remove obsolete defines.
13721 * sysdep.c: Include limits.h unconditionally.
13723 Assume support for memcmp, memcpy, memmove, memset.
13724 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13725 * regex.c (memcmp, memcpy):
13726 Remove; we assume C89 now.
13728 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13729 (__malloc_safe_bcopy): Remove; no longer needed.
13731 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13732 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13733 well either way, and we prefer signed to unsigned.
13735 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13737 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13738 closes the connection while we're reading (bug#9182).
13740 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13742 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13743 are specified (Bug#9168).
13745 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13747 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13748 Found by GCC static checking and --with-wide-int on a 32-bit host.
13750 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13752 * xdisp.c (compute_display_string_pos): Fix logic of caching
13753 previous display string position. Initialize cached_prev_pos to
13754 -1. Fixes slow-down at the beginning of a buffer.
13756 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13758 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13759 for attrs[LFACE_FONTSET_INDEX].
13761 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13763 * xml.c (parse_region): Remove unused local
13764 that was recently introduced.
13766 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13768 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13769 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13771 * xdisp.c (move_it_in_display_line_to): Record the best matching
13772 position for TO_CHARPOS while scanning the line, and restore it on
13773 exit if none of the characters scanned was an exact match.
13774 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13775 when exact match is impossible due to invisible text, and the
13776 lines are truncated.
13778 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13780 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13783 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13785 Fix a significant slow-down of cursor motion with C-n, C-p,
13786 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13787 auto-repeat under bidi redisplay in fontified buffers.
13788 * xdisp.c (compute_stop_pos_backwards): New function.
13789 (next_element_from_buffer): Call compute_stop_pos_backwards to
13790 find a suitable prev_stop when we find ourselves before
13792 (reseat): Don't look for prev_stop, as that could mean a very long
13794 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13795 <cached_disp_overlay_modiff>: Cache for last found display string
13797 (compute_display_string_pos): Return the cached position if asked
13798 about the same buffer in the same area of character positions, and
13799 the buffer wasn't changed since the time the display string
13800 position was cached.
13802 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13804 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13805 is an integer, which is important for empty lines. (Bug#9149)
13807 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13809 * frame.c (Fmodify_frame_parameters): In tty case, update the
13810 default face if necessary (Bug#4238).
13812 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13814 * editfns.c (Fstring_to_char): No need to explain what a character
13815 is in the docstring (Bug#6576).
13817 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13819 * xml.c (parse_region): Make sure we always return a tree.
13821 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13823 * xml.c (parse_region): If a document contains only comments,
13826 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13828 * xml.c (make_dom): Return comments, too.
13830 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13833 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13834 and the surrounding thread.
13835 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13836 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13837 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13839 * s/openbsd.h (BROKEN_SIGIO): Define.
13840 * unexelf.c (unexec) [__OpenBSD__]:
13841 Don't update the .mdebug section of the Alpha COFF symbol table.
13843 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13845 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13848 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13850 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13851 This fixes some race conditions on the permissions of any newly
13854 * alloc.c (valid_pointer_p): Use pipe, not open.
13855 This fixes some permissions issues when debugging.
13857 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13858 If fchown fails to set both uid and gid, try to set just gid,
13859 as that is sometimes allowed. Adjust the file's mode to eliminate
13860 setuid or setgid bits that are inappropriate if fchown fails.
13862 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13864 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13865 to compare Lisp_Objects.
13866 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
13867 global_gnutls_log_level, don't mistake it for a Lisp_Object.
13868 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
13870 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13872 * lread.c (read_integer): Unread even EOF character.
13873 (read1): Likewise. Properly record start position of symbol.
13875 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13876 symbol character follows.
13878 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13880 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13881 This works around a problem with the previous change to Fcopy_file.
13882 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13883 and without this change, GCC might complain about discarding
13884 fchown's return value.
13886 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13888 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13890 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13892 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13894 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13896 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13897 it's used from the C level.
13899 * process.c: Use the same condition for POLL_FOR_INPUT in both
13900 keyboard.c and process.c (bug#1858).
13902 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13904 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13905 (Fgnutls_boot): Use it.
13907 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13909 * doc.c (Fsubstitute_command_keys): Revert last change.
13911 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13913 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13914 quotes the next character, and doesn't affect other longer
13915 sequences (bug#8935).
13917 * lread.c (syms_of_lread): Clarify that is isn't only
13918 `eval-buffer' and `eval-defun' that's affected by
13919 `lexical-binding' (bug#8460).
13921 2011-07-15 Eli Zaretskii <eliz@gnu.org>
13923 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
13924 bidi redisplay when a line includes both an image and is truncated.
13926 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
13928 Fix minor problems found by static checking.
13929 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13930 (elsz): Now a signed constant, not a size_t var. We prefer signed

13982 the iterator is before prev_stop.

14464 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

14501 Random fixes. E.g., (random) never returned negative values.
14502 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14503 subseconds part to the entropy, as that's a bit more random.
14504 Prefer signed to unsigned, since the signedness doesn't matter and
14505 in general we prefer signed. When given a limit, use a
14506 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14507 latter isn't right if USE_2_TAGS_FOR_INTS.
14508 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14509 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14521 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14522 This is more efficient than Ffile_directory_p and avoids a minor race.

14526 * buffer.c (Foverlay_put): Say what the return value is
14529 * fileio.c (barf_or_query_if_file_exists): Check first if the file

14533 error be more correct.
14535 * fns.c (Frequire): Remove the mention of the .gz files, since

14549 Qgnutls_bootprop_verify_error (which is no longer used).
14551 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
14552 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
14553 Also (re)move comments that are misplaced or no longer relevant.
14555 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
14557 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

14582 * lread.c (syms_of_lread): Mention single symbols defined by

14654 * eval.c (struct backtrace): Simplify and port the data structure.
14655 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14656 signed bit field, as this assumption is not portable and it makes
14657 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14658 "char debug_on_exit : 1" as this is not portable either; instead,
14659 use the portable "unsigned int debug_on_exit : 1". Remove unused
14660 member evalargs. Remove obsolete comments about cc bombing out.
14662 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

14756 Use gnulib's dup2 module instead of rolling our own.

14816 * xmenu.c (syms_of_xmenu):
14817 * xsettings.c (syms_of_xsettings):

14820 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
14822 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
14824 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
14826 Integer and buffer overflow fixes (Bug#8873).
14828 * print.c (printchar, strout): Check for string overflow.
14829 (PRINTPREPARE, printchar, strout):
14830 Don't set size unless allocation succeeds.
14832 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14833 for sizes. Check for string overflow more accurately.
14834 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
14836 * macros.c: Integer and buffer overflow fixes.
14837 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14838 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
14839 Use ptrdiff_t, not int, for sizes.
14840 Don't increment bufsize until after realloc succeeds.
14841 Check for size-calculation overflow.
14842 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
14844 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14846 * lread.c: Integer overflow fixes.
14847 (read_integer): Radix is now EMACS_INT, not int,
14848 to improve quality of diagnostics for out-of-range radices.
14849 Calculate buffer size correctly for out-of-range radices.
14850 (read1): Check for integer overflow in radices, and in
14851 read-circle numbers.
14852 (read_escape): Avoid int overflow.
14853 (Fload, openp, read_buffer_size, read1)
14854 (substitute_object_recurse, read_vector, read_list, map_obarray):
14855 Use ptrdiff_t, not int, for sizes.
14856 (read1): Use EMACS_INT, not int, for sizes.
14857 Check for size overflow.
14859 * image.c (cache_image): Check for size arithmetic overflow.
14861 * lread.c: Integer overflow issues.
14862 (saved_doc_string_size, saved_doc_string_length)
14863 (prev_saved_doc_string_size, prev_saved_doc_string_length):
14864 Now ptrdiff_t, not int.

14868 (read_escape): Check for hex character overflow.
14870 2011-06-22 Leo Liu <sdl.web@gmail.com>
14872 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14873 Move to minibuffer.el.
14875 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14877 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14878 The following patches are for when GLYPH_DEBUG && !XASSERT.
14879 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14880 * dispnew.c (flush_stdout):
14881 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14882 Mark as externally visible.
14883 * dispnew.c (check_window_matrix_pointers): Now static.
14884 * dispnew.c (window_to_frame_vpos):
14885 * xfns.c (unwind_create_frame):
14886 * xterm.c (x_check_font): Remove unused local.
14887 * scroll.c (CHECK_BOUNDS):
14888 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14889 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14890 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14891 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14892 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14894 (debug_method_add): Use va_list and vsprintf rather than relying
14895 on undefined behavior with wrong number of arguments.
14896 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14897 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14898 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14899 since we're not interested in debugging glyphs with old libraries.
14900 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14901 GCC 4.6.0's static checking.
14903 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14905 Integer overflow and signedness fixes (Bug#8873).
14906 A few related buffer overrun fixes, too.

14914 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
14915 (x_create_bitmap_from_xpm_data):
14916 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
14917 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
14919 * xfaces.c (load_pixmap):
14920 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
14921 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14922 (.bitmaps_last, struct x_output.icon_bitmap):
14923 Use ptrdiff_t, not int, for bitmap indexes.
14924 (x_allocate_bitmap_record): Check for size overflow.
14925 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14927 Use ptrdiff_t, not int, for overlay counts.
14928 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14929 * editfns.c (overlays_around, get_pos_property):
14930 * textprop.c (get_char_property_and_overlay):
14931 * xdisp.c (next_overlay_change, note_mouse_highlight):
14932 * xfaces.c (face_at_buffer_position):
14933 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14934 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14935 (Fnext_overlay_change, Fprevious_overlay_change)
14936 (mouse_face_overlay_overlaps, Foverlays_in):
14937 Use ptrdiff_t, not int, for sizes.
14938 (overlays_at, overlays_in): Check for size-calculation overflow.
14940 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14942 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14943 (x_session_initialize): Do not assume string length fits in int.
14945 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14946 This is unlikely, but can occur if DPI is outlandish.
14948 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14949 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14951 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14952 * xrdb.c (magic_file_p, search_magic_path):
14953 Omit last arg SUFFIX; it was always 0. All callers changed.
14954 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14956 * xfont.c (xfont_match): Avoid need for strlen.
14958 * xfns.c: Don't assume strlen fits in int.
14959 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
14961 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14962 not unsigned long, as we prefer signed integers. All callers changed.
14963 Detect integer overflow in repeat count.
14964 (message_dolog): Don't assume print length fits in 39 bytes.
14965 (display_mode_element): Don't assume strlen fits in int.
14967 * termcap.c: Don't assume sizes fit in int and never overflow.
14968 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14969 (gobble_line): Check for size-calculation overflow.
14971 * minibuf.c (Fread_buffer):
14972 * lread.c (intern, intern_c_string):
14973 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
14974 Don't assume string length fits in int.
14976 * keyboard.c (parse_tool_bar_item):
14977 * gtkutil.c (style_changed_cb): Avoid need for strlen.
14979 * font.c: Don't assume string length fits in int.
14980 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
14981 Use ptrdiff_t, not int.
14982 (font_intern_prop): Don't assume string length fits in int.
14983 Don't assume integer property fits in fixnum.
14984 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14986 * filelock.c: Fix some buffer overrun and integer overflow issues.
14987 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14988 Reformulate so as not to need the command string.
14989 Invoke gzip -cd rather than gunzip, as it's more portable.
14990 (lock_info_type, lock_file_1, lock_file):
14991 Don't assume pid_t and time_t fit in unsigned long.
14992 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14993 (current_lock_owner): Prefer signed type for sizes.
14994 Use memcpy, not strncpy, where memcpy is what is really wanted.
14995 Don't assume (via atoi) that time_t and pid_t fit in int.
14996 Check for time_t and/or pid_t out of range, e.g., via a network share.
14997 Don't alloca where an auto var works fine.
14999 * fileio.c: Fix some integer overflow issues.
15000 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15001 Don't assume string length fits in int.
15002 (directory_file_name): Don't assume string length fits in long.
15003 (make_temp_name): Don't assume pid fits in int, or that its print
15004 length is less than 20.
15006 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15008 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15010 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15012 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15013 We prefer signed integers, even for size calculations.
15015 * emacs.c: Don't assume string length fits in 'int'.
15016 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15017 (main): Don't invoke strlen when not needed.
15019 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15020 (XD_DEBUG_MESSAGE): Don't waste a byte.
15022 * callproc.c (getenv_internal_1, getenv_internal)
15023 (Fgetenv_internal):
15024 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15026 * lread.c (invalid_syntax): Omit length argument.
15027 All uses changed. This doesn't fix a bug, but it simplifies the
15028 code away from its former Hollerith-constant appearance, and it's
15029 one less 'int' to worry about when looking at integer-overflow issues.
15030 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15032 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15033 This didn't break anything, but it didn't help either.
15034 It's confusing to put a bogus integer in a place where the actual
15035 value does not matter.
15036 (LIST_END_P): Remove unused macro and its bogus comment.
15037 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15039 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15040 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15042 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15043 We prefer signed types, and the value cannot exceed the EMACS_INT
15044 range anyway (because otherwise the length would not be representable).
15045 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15046 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15047 This avoids a GCC warning when WIDE_EMACS_INT.
15049 * indent.c (sane_tab_width): New function.
15050 (current_column, scan_for_column, Findent_to, position_indentation)
15051 (compute_motion): Use it. This is just for clarity.
15052 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15054 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15056 * lisp.h (lint_assume): New macro.
15057 * composite.c (composition_gstring_put_cache):
15058 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15060 * editfns.c, insdel.c:
15061 Omit unnecessary forward decls, to simplify future changes.
15063 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15065 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15067 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15068 Use much-faster test for byte-length change.
15069 Don't assume string byte-length fits in 'int'.
15070 Check that character arg fits in 'int'.
15071 (mapcar1): Declare byte as byte, for clarity.
15073 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15075 * fns.c (concat): Catch string overflow earlier.
15076 Do not rely on integer wraparound.
15078 * dispextern.h (struct it.overlay_strings_charpos)
15079 (struct it.selective): Now EMACS_INT, not int.
15080 * xdisp.c (forward_to_next_line_start)
15081 (back_to_previous_visible_line_start)
15082 (reseat_at_next_visible_line_start, next_element_from_buffer):
15083 Don't arbitrarily truncate the value of 'selective' to int.
15085 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15087 * composite.c: Don't truncate sizes to 'int'.
15088 (composition_gstring_p, composition_reseat_it)
15089 (composition_adjust_point): Use EMACS_INT, not int.
15090 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15091 not EMACS_UINT, for indexes.
15093 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15095 * buffer.c: Include <verify.h>.
15096 (struct sortvec.priority, struct sortstr.priority):
15097 Now EMACS_INT, not int.
15098 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15099 (struct sortstr.size, record_overlay_string)
15100 (struct sortstrlist.size, struct sortlist.used):
15101 Don't truncate size to int.
15102 (record_overlay_string): Check for size-calculation overflow.
15103 (init_buffer_once): Check at compile-time, not run-time.
15105 2011-06-22 Jim Meyering <meyering@redhat.com>
15107 Don't leak an XBM-image-sized buffer
15108 * image.c (xbm_load): Free the image buffer after using it.
15110 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15113 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15114 that Sun C diagnosed.
15115 * fns.c (secure_hash): Fix pointer signedness issue.
15116 * intervals.c (static_offset_intervals): New function.
15117 (offset_intervals): Use it.
15119 2011-06-21 Leo Liu <sdl.web@gmail.com>
15122 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15125 * fns.c (secure_hash): Rename from crypto_hash_function and change
15126 the first arg to accept symbols.
15127 (Fsecure_hash): New primitive.
15128 (syms_of_fns): New symbols.
15130 2011-06-20 Deniz Dogan <deniz@dogan.se>
15132 * process.c (Fset_process_buffer): Clarify return value in
15135 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15137 * dispnew.c (add_window_display_history): Use BVAR.
15139 * xdisp.c (debug_method_add): Use BVAR.
15140 (check_window_end, dump_glyph_matrix, dump_glyph)
15141 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15143 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15146 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15147 check till after the cache is created in init_frame_faces.
15149 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15151 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15153 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15155 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15156 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15157 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15159 Improve buffer-overflow checking (Bug#8873).
15160 * fileio.c (Finsert_file_contents):
15161 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15162 Remove the old (too-loose) buffer overflow checks.
15163 They weren't needed, since make_gap checks for buffer overflow.
15164 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15165 The old code merely checked for Emacs fixnum overflow, and relied
15166 on undefined (wraparound) behavior. The new code avoids undefined
15167 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15169 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15170 Tune. Don't use wider integers than needed. Don't use alloca.
15171 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15173 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15175 * insdel.c, lisp.h (buffer_overflow): New function.
15176 (insert_from_buffer_1, replace_range, replace_range_2):
15177 * insdel.c (make_gap_larger):
15178 * editfns.c (Finsert_char):
15179 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15181 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15183 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15185 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15187 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15188 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15190 * fileio.c: Don't assume EMACS_INT fits in off_t.
15191 (emacs_lseek): New static function.
15192 (Finsert_file_contents, Fwrite_region): Use it.
15193 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15195 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15197 * fns.c: Don't overflow int when computing a list length.
15198 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15199 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15200 truncation on 64-bit hosts. Check for QUIT every
15201 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15202 faster and is responsive enough.
15203 (Flength): Report an error instead of overflowing an integer.
15204 (Fsafe_length): Return a float if the value is not representable
15205 as a fixnum. This shouldn't happen except in contrived situations.
15206 (Fnthcdr, Fsort): Don't assume list length fits in int.
15207 (Fcopy_sequence): Don't assume vector length fits in int.
15209 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15210 (header_size, word_size): New constants.
15211 (allocate_vectorlike): Don't check size overflow here.
15212 (allocate_vector): Check it here instead, since this is the only
15213 caller of allocate_vectorlike that could cause overflow.
15214 Check that the new vector's length is representable as a fixnum.
15216 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15217 The previous code was bogus. For example, next_almost_prime (32)
15218 returned 39, which is undesirable as it is a multiple of 3; and
15219 next_almost_prime (24) returned 25, which is a multiple of 5 so
15220 why was the code bothering to check for multiples of 7?
15222 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15224 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15226 Variadic C functions now count arguments with ptrdiff_t.
15227 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15228 Back then I didn't know that the Emacs coding style prefers signed int.
15229 Also, in the meantime I found a few more instances where arguments
15230 were being counted with int, which may truncate counts on 64-bit
15231 machines, or EMACS_INT, which may be unnecessarily wide.
15232 * lisp.h (struct Lisp_Subr.function.aMANY)
15233 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15234 Arg counts are now ptrdiff_t, not size_t.
15235 All variadic functions and their callers changed accordingly.
15236 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15237 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15238 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15239 * callint.c (Fcall_interactively): Check arg count for overflow,
15240 to avoid potential buffer overrun. Use signed char, not 'int',
15241 for 'varies' array, so that we needn't bother to check its size
15242 calculation for overflow.
15243 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15244 * eval.c (apply_lambda):
15245 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15246 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15247 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15249 * callint.c (Fcall_interactively): Don't use index var as event count.
15251 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15252 * mem-limits.h (SIZE): Remove; no longer used.
15254 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15256 Remove unnecessary casts.
15257 * xterm.c (x_term_init):
15258 * xfns.c (x_set_border_pixel):
15259 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15260 These aren't needed now that we assume ANSI C.
15262 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15263 It's more likely to cause problems (due to unsigned overflow)
15266 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15268 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15270 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15272 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15274 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15276 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15278 GLYPH_CODE_FACE returns EMACS_INT, not int.
15279 * dispextern.h (merge_faces):
15280 * xfaces.c (merge_faces):
15281 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15282 Don't assume EMACS_INT fits in int.
15284 * character.h (CHAR_VALID_P): Remove unused parameter.
15285 * fontset.c, lisp.h, xdisp.c: All uses changed.
15287 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15289 * fns.c (concat): Minor tuning based on overflow analysis.
15290 This doesn't fix any bugs. Use int to hold character, instead
15291 of constantly refetching from Emacs object. Use XFASTINT, not
15292 XINT, for value known to be a character. Don't bother comparing
15293 a single byte to 0400, as it's always less.
15295 * floatfns.c (Fexpt):
15296 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15298 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15301 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15303 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15304 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15305 incorrectly succeed when S was a string, because 4294967386 was
15306 truncated before it was used.
15308 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15309 Otherwise, an out-of-range integer could cause undefined behavior
15312 * composite.c: Use int, not EMACS_INT, for characters.
15313 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15314 EMACS_INT, for values that are known to be in character range.
15315 This doesn't fix any bugs but is the usual style inside Emacs and
15316 may generate better code on 32-bit machines.
15318 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15319 This is for reasons similar to the recent CHAR_STRING fix.
15320 * charset.c (Fencode_char): Check that character arg is actually
15321 a character. Pass an int to ENCODE_CHAR.
15322 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15323 wider than 'int', as a compile-time check to prevent future regressions
15326 * character.c (char_string): Remove unnecessary casts.
15328 Make sure a 64-bit char is never passed to CHAR_STRING.
15329 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15330 by silently ignoring the top 32 bits, allowing some values
15331 that were far too large to be valid characters.
15332 * character.h: Include <verify.h>.
15333 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15334 arguments are no wider than unsigned, as a compile-time check
15335 to prevent future regressions in this area.
15337 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15338 (Fsubst_char_in_region):
15340 * xdisp.c (decode_mode_spec_coding):
15341 Adjust to CHAR_STRING's new requirement.
15342 * editfns.c (Finsert_char, Fsubst_char_in_region):
15343 * fns.c (concat): Check that character args are actually
15344 characters. Without this test, these functions did the wrong
15345 thing with wildly out-of-range values on 64-bit hosts.
15347 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15348 These casts should not be needed on 32-bit hosts, either.
15349 * keyboard.c (read_char):
15350 * lread.c (Fload): Remove casts to unsigned.
15352 * lisp.h (UNSIGNED_CMP): New macro.
15353 This fixes comparison bugs on 64-bit hosts.
15354 (ASCII_CHAR_P): Use it.
15355 * casefiddle.c (casify_object):
15356 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15357 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15358 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15359 * dispextern.h (FACE_FROM_ID):
15360 * keyboard.c (read_char): Use UNSIGNED_CMP.
15362 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15363 not to EMACS_INT, to avoid GCC warning.
15365 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15367 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15368 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15369 isn't needed on 32-bit machines.
15371 * buffer.c (Fgenerate_new_buffer_name):
15372 Use EMACS_INT for count, not int.
15373 (advance_to_char_boundary): Return EMACS_INT, not int.
15375 * data.c (Qcompiled_function): Now static.
15377 * window.c (window_body_lines): Now static.
15379 * image.c (gif_load): Rename local to avoid shadowing.
15381 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15382 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15383 * alloc.c (make_save_value): Integer argument is now of type
15384 ptrdiff_t, not int.
15385 (mark_object): Use ptrdiff_t, not int.
15386 * lisp.h (pD): New macro.
15387 * print.c (print_object): Use it.
15389 * alloc.c: Use EMACS_INT, not int, to count objects.
15390 (total_conses, total_markers, total_symbols, total_vector_size)
15391 (total_free_conses, total_free_markers, total_free_symbols)
15392 (total_free_floats, total_floats, total_free_intervals)
15393 (total_intervals, total_strings, total_free_strings):
15394 Now EMACS_INT, not int. All uses changed.
15395 (Fgarbage_collect): Compute overall total using a double, so that
15396 integer overflow is less likely to be a problem. Check for overflow
15397 when converting back to an integer.
15398 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15399 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15400 These were 'int' variables that could overflow on 64-bit hosts;
15401 they were never used, so remove them instead of repairing them.
15402 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15403 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15404 Previously, this ceilinged at INT_MAX, but that doesn't work on
15406 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15408 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15409 (allocate_vectorlike): Check for ptrdiff_t overflow.
15410 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15411 when a (possibly-narrower) signed value would do just as well.
15412 We prefer using signed arithmetic, to avoid comparison confusion.
15414 * alloc.c: Catch some string size overflows that we were missing.
15415 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15416 for convenience in STRING_BYTES_MAX.
15417 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15418 The definition here is exact; the one in lisp.h was approximate.
15419 (allocate_string_data): Check for string overflow. This catches
15420 some instances we weren't catching before. Also, it catches
15421 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15422 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15423 and ptrdiff_t and EMACS_INT are both 64 bits.
15425 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15426 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15427 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15429 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15431 * alloc.c (Fmake_string): Check for out-of-range init.
15433 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15435 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15437 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15439 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15440 xg_get_default_scrollbar_width.
15442 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
15443 (int_gtk_range_get_value): Move to the scroll bar part of the file.
15444 (style_changed_cb): Call update_theme_scrollbar_width and call
15445 x_set_scroll_bar_default_width and xg_frame_set_char_size for
15446 all frames (Bug#8505).
15447 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
15448 Call gtk_window_set_resizable if HAVE_GTK3.
15449 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
15450 and height if HAVE_GTK3 (Bug#8505).
15451 (scroll_bar_width_for_theme): New variable.
15452 (update_theme_scrollbar_width): New function.
15453 (xg_get_default_scrollbar_width): Move code to
15454 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
15455 (xg_initialize): Call update_theme_scrollbar_width.
15457 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
15459 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
15461 2011-06-12 Martin Rudalics <rudalics@gmx.at>
15463 * frame.c (make_frame): Call other_buffer_safely instead of
15466 * window.c (temp_output_buffer_show): Call display_buffer with
15467 second argument Vtemp_buffer_show_specifiers and reset latter
15468 immediately after the call.
15469 (Vtemp_buffer_show_specifiers): New variable.
15470 (auto_window_vscroll_p, next_screen_context_lines)
15471 (Vscroll_preserve_screen_position): Remove leading asterisks from

15516 * window.c (delete_deletable_window): Re-add.
15517 (Fset_window_configuration): Rewrite to handle dead buffers and
15518 consequently deletable windows.
15519 (window_tree, Fwindow_tree): Remove. Supply functionality in
15521 (compare_window_configurations): Simplify code.

15654 Remove static from declaration of Qdelete_window, it's
15655 temporarily needed by Fbury_buffer.
15656 (replace_window): Don't assign orig_top_line and
15658 (Fdelete_window, delete_window): Remove. Window deletion is

15660 (window_loop): Remove DELETE_OTHER_WINDOWS case.
15661 Replace Fdelete_window calls with calls to Qdelete_window.
15662 (Fdelete_other_windows): Remove. Deleting other windows is

16035 value of a `display' property is a "replacing spec".
16036 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16037 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

16067 * gnutls.c: Use Emacs's memory allocators.
16068 Without this change, the gnutls library would invoke malloc etc.
16069 directly, which causes problems on non-SYNC_INPUT hosts, and which
16070 runs afoul of improving memory_full behavior. (Bug#8761)
16071 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16072 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16073 xfree instead of the default malloc, realloc, free.
16074 (Fgnutls_boot): No need to check for memory allocation failure,
16075 since xmalloc does that for us.
16077 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

16104 need to be updated by these changes.
16105 * fns.c (make_hash_table, maybe_resize_hash_table):
16106 Check for integer overflow with large hash tables.
16107 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16108 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16109 (SXHASH_REDUCE): New macro.
16110 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16111 Use it instead of discarding useful hash info with large hash values.
16112 (sxhash_float): New function.
16113 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16114 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16115 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16116 Rewrite to use FIXNUM_BITS, as this simplifies things.
16117 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16118 Adjust signatures to match updated version of code.
16119 (consing_since_gc): Now EMACS_INT, since a single hash table can
16120 use more than INT_MAX bytes.
16122 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
16124 Make it possible to build with GCC-4.6+ -O2 -flto.
16126 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
16128 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
16130 * minibuf.c (get_minibuffer, read_minibuf_unwind):
16131 Call minibuffer-inactive-mode.
16133 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
16135 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
16136 Update dependencies.
16138 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16140 * data.c (init_data): Remove code for UTS, this system is not
16143 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16145 Don't force ./temacs to start in terminal mode.
16147 * frame.c (make_initial_frame): Initialize faces in all cases, not
16148 only when CANNOT_DUMP is defined.
16149 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
16151 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16153 * dispnew.c (add_window_display_history): Use const for the string
16154 pointer. Remove declaration, not needed.
16156 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16158 Use 'inline', not 'INLINE'.
16159 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
16160 * alloc.c, fontset.c (INLINE): Remove.
16161 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
16162 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
16163 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16164 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16165 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16167 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16169 Make it possible to run ./temacs.
16171 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16172 syms_of_callproc does the same thing. Remove test for
16173 "initialized", do it in the caller.
16174 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16176 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16178 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16179 (read_minibuf): Use get_minibuffer.
16180 (syms_of_minibuf): Use DEFSYM.
16181 (Qmetadata): New var.
16182 * data.c (Qbuffer): Don't make it static.
16183 (syms_of_data): Use DEFSYM.
16185 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16187 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
16188 (CCL_CODE_MIN): New macro.
16190 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16192 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16194 * eval.c (Qdebug): Now static.
16195 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16196 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
16197 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
16199 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16201 * image.c: Various fixes to ImageMagick code comments.
16202 (Fimagemagick_types): Doc fix.
16204 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16206 Minor fixes prompted by GCC 4.6.0 warnings.
16208 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16210 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16211 (x_clipboard_manager_save_all): Move extern decl to ...
16212 * xterm.h: ... here, so that it can be checked for consistency.
16214 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16216 * xselect.c (x_clipboard_manager_save_frame)
16217 (x_clipboard_manager_save_all): New functions.
16218 (Fx_clipboard_manager_save): Lisp function deleted.
16220 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16221 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16223 * xterm.h: Update prototype.
16225 2011-05-28 William Xu <william.xwl@gmail.com>
16227 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16228 exiting (Bug#8239).
16230 2011-05-28 Jim Meyering <meyering@redhat.com>
16232 Avoid a sign-extension bug in crypto_hash_function.
16233 * fns.c (to_uchar): Define.
16234 (crypto_hash_function): Use it to convert some newly-signed
16235 variables to unsigned, to avoid sign-extension bugs. For example,
16236 without this change, (md5 "truc") would evaluate to
16237 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16238 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16239 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16241 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16243 Integer overflow fixes.
16245 * dbusbind.c: Serial number integer overflow fixes.
16246 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16247 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16248 to hold a serial number that is too large for a fixnum.
16249 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16250 Check for serial numbers out of range. Decode any serial number
16251 that was so large that it became a float. (Bug#8722)
16253 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16254 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16255 Use XFASTINT rather than XUINT when numbers are nonnegative.
16256 (xd_append_arg, Fdbus_method_return_internal):
16257 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16258 arguments, check that Lisp number is nonnegative, rather than
16259 silently wrapping negative numbers around. (Bug#8722)
16260 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16263 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16265 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16267 ccl: Add integer overflow checks.
16268 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16269 (IN_INT_RANGE): New macros.
16270 (ccl_driver): Use them to check for integer overflow when
16271 decoding a CCL program. Many of the new checks are whether XINT (x)
16272 fits in int; it doesn't always, on 64-bit hosts. The new version
16273 doesn't catch all possible integer overflows, but it's an
16274 improvement. (Bug#8719)
16276 * alloc.c (make_event_array): Use XINT, not XUINT.
16277 There's no need for unsigned here.
16279 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16280 This follows up to the 2011-05-06 change that substituted uintptr_t
16281 for EMACS_INT. This case wasn't caught back then.
16283 Rework Fformat to avoid integer overflow issues.
16284 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16285 now (part of C89). Include <verify.h>.
16286 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16287 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16288 (Fformat): Avoid the prepass trying to compute sizes; it was only
16289 approximate and thus did not catch overflow reliably. Instead, walk
16290 through the format just once, formatting and computing sizes as we go,
16291 checking for integer overflow at every step, and allocating a larger
16292 buffer as needed. Keep track separately whether the format is
16293 multibyte. Keep only the most-recently calculated precision, rather
16294 than them all. Record whether each argument has been converted to
16295 string. Use EMACS_INT, not int, for byte and char and arg counts.
16296 Support field widths and precisions larger than INT_MAX. Avoid
16297 sprintf's undefined behavior with conversion specifications such as %#d
16298 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16299 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16300 formatting out-of-range floating point numbers with int
16301 formats. (Bug#8668)
16303 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16305 * data.c: Avoid integer truncation in expressions involving floats.
16306 * data.c: Include <intprops.h>.
16307 (arith_driver): When there's an integer overflow in an expression
16308 involving floating point, convert the integers to floating point
16309 so that the resulting value does not suffer from catastrophic
16310 integer truncation. For example, on a 64-bit host (* 4
16311 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16312 Do not rely on undefined behavior after integer overflow.
16314 merge count_size_as_multibyte, parse_str_to_multibyte
16315 * character.c, character.h (count_size_as_multibyte):
16316 Rename from parse_str_to_multibyte; all uses changed.
16317 Check for integer overflow.
16318 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16319 since it's now a duplicate of the other. This is more of
16320 a character than a buffer op, so better that it's in character.c.
16321 * fns.c, print.c: Adjust to above changes.
16323 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16325 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16327 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16329 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16330 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16331 (x_clipboard_manager_save): Now static.
16332 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16334 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16335 (crypto_hash_function): Now static.
16336 Fix pointer signedness problems. Avoid unnecessary initializations.
16338 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16340 * termhooks.h (Vselection_alist): Make it terminal-local.
16342 * terminal.c (create_terminal): Initialize it.
16344 * xselect.c: Support for clipboard managers.
16345 (Vselection_alist): Move to termhooks.h as terminal-local var.
16346 (LOCAL_SELECTION): New macro.
16347 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16348 (symbol_to_x_atom): Remove gratuitous arg.
16349 (x_handle_selection_request, lisp_data_to_selection_data)
16350 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16351 (x_own_selection, x_get_local_selection, x_convert_selection):
16352 New arg, specifying work frame. Use terminal-local Vselection_alist.
16353 (some_frame_on_display): Delete unused function.
16354 (Fx_own_selection_internal, Fx_get_selection_internal)
16355 (Fx_disown_selection_internal, Fx_selection_owner_p)
16356 (Fx_selection_exists_p): New optional frame arg.
16357 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16358 (x_handle_selection_clear): Don't treat other terminals with the
16359 same keyboard specially. Use the terminal-local Vselection_alist.
16360 (x_clear_frame_selections): Use Frun_hook_with_args.
16362 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16364 * xterm.h: Add support for those atoms.
16366 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16368 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16369 (converted_selections, conversion_fail_tag): New global variables.
16370 (x_selection_request_lisp_error): Free the above.
16371 (x_get_local_selection): Remove unnecessary code.
16372 (x_reply_selection_request): Args changed; handle arbitrary array
16373 of converted selections stored in converted_selections.
16374 Separate the XChangeProperty and SelectionNotify steps.
16375 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16376 (x_convert_selection): New function.
16377 (x_handle_selection_event): Simplify.
16378 (x_get_foreign_selection): Don't ignore incoming requests while
16379 waiting for an answer; this will fail when we implement
16380 SAVE_TARGETS, and seems unnecessary anyway.
16381 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16382 (Vx_sent_selection_functions): Doc fix.
16384 2011-05-26 Leo Liu <sdl.web@gmail.com>
16386 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16388 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16390 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16392 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16393 for fringe update if it has periodic bitmap.
16394 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16395 and fringe_bitmap_periodic_p.
16397 * fringe.c (get_fringe_bitmap_data): New function.
16398 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16399 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16400 row. Mark glyph row for fringe update if periodicity changed.
16402 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16403 for fringe update unless it has periodic bitmap.
16405 2011-05-25 Kenichi Handa <handa@m17n.org>
16407 * xdisp.c (get_next_display_element): Set correct it->face_id for
16408 a static composition.
16410 2011-05-24 Leo Liu <sdl.web@gmail.com>
16413 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16415 * fns.c (crypto_hash_function, Fsha1): New function.
16416 (Fmd5): Use crypto_hash_function.
16417 (syms_of_fns): Add Ssha1.
16419 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16421 * gnutls.c: Remove unused macros.
16422 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16423 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16424 Remove macros that are defined and never used.
16425 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16427 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16429 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16430 (Fx_get_selection_internal): Minor cleanup.
16431 (Fx_own_selection_internal): Rename arguments for consistency with
16434 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16436 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16438 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16440 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
16442 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16444 * dispnew.c (scrolling_window): Don't exclude the case that the
16445 last enabled row in the desired matrix touches the bottom boundary.
16447 2011-05-21 Glenn Morris <rgm@gnu.org>
16449 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16450 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16451 and add some more files.
16453 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16455 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16456 report_file_error introduced by the change from 2011-05-07.
16458 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16460 * systime.h (Time): Define only if emacs is defined.
16461 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16462 where the include path doesn't have X11/X.h by default. See
16463 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16465 2011-05-20 Kenichi Handa <handa@m17n.org>
16467 * composite.c (find_automatic_composition): Fix previous change.
16469 2011-05-20 Glenn Morris <rgm@gnu.org>
16471 * lisp.mk: New file, split from Makefile.in.
16472 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16473 (shortlisp): Remove.
16474 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16476 2011-05-19 Glenn Morris <rgm@gnu.org>
16478 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16479 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16480 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16481 (lisp): Set the order to that of loadup.el.
16482 (shortlisp): Make it a copy of $lisp.
16483 (SOME_MACHINE_LISP): Remove.
16484 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16485 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16487 2011-05-18 Kenichi Handa <handa@m17n.org>
16489 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16490 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16491 (find_automatic_composition): Mostly rewrite for efficiency.
16493 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16495 * makefile.w32-in: Update dependencies.
16497 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16499 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16500 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16502 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16504 Fix some integer overflow issues, such as string length overflow.
16506 * insdel.c (count_size_as_multibyte): Check for string overflow.
16508 * character.c (lisp_string_width): Check for string overflow.
16509 Use EMACS_INT, not int, for string indexes and lengths; in
16510 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16511 the resulting string length overflows an EMACS_INT; instead,
16512 report a string overflow if no precision given. When checking for
16513 precision exhaustion, use a check that cannot possibly have
16514 integer overflow. (Bug#8675)
16515 * character.h (lisp_string_width): Adjust to new signature.
16517 * alloc.c (string_overflow): New function.
16518 (Fmake_string): Use it. This doesn't change behavior, but saves
16519 a few bytes and will simplify future changes.
16520 * character.c (string_escape_byte8): Likewise.
16521 * lisp.h (string_overflow): New decl.
16523 Fixups, following up to the user-interface timestamp change.
16524 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16525 for UI timestamps, instead of unsigned long.
16526 * msdos.c (mouse_get_pos): Likewise.
16527 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16528 * w32gui.h (Time): Define by including "systime.h" rather than by
16529 declaring it ourselves. (Bug#8664)
16531 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16532 * image.c (clear_image_cache): Likewise.
16534 * term.c (term_mouse_position): Don't assume time_t wraparound.
16536 Be more systematic about user-interface timestamps.
16537 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16538 and sometimes 'EMACS_UINT', to represent these timestamps.
16539 This change causes it to use 'Time' uniformly, as that's what X uses.
16540 This makes the code easier to follow, and makes it easier to catch
16541 integer overflow bugs such as Bug#8664.
16542 * frame.c (Fmouse_position, Fmouse_pixel_position):
16543 Use Time, not unsigned long, for user-interface timestamps.
16544 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16545 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16546 * keyboard.h (last_event_timestamp): Likewise.
16547 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16548 * menu.h (xmenu_show): Likewise.
16549 * term.c (term_mouse_position): Likewise.
16550 * termhooks.h (struct input_event.timestamp): Likewise.
16551 (struct terminal.mouse_position_hook): Likewise.
16552 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16553 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16554 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16555 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16556 what it was before.
16557 * menu.h, termhooks.h: Include "systime.h", for Time.
16559 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16560 Don't assume that the difference between two unsigned long values
16561 can fit into an integer. At this point, we know button_down_time
16562 <= event->timestamp, so the difference must be nonnegative, so
16563 there's no need to cast the result if double-click-time is
16564 nonnegative, as it should be; check that it's nonnegative, just in
16565 case. This bug is triggered when events are more than 2**31 ms
16566 apart (about 25 days). (Bug#8664)
16568 * xselect.c (last_event_timestamp): Remove duplicate decl.
16569 (x_own_selection): Remove needless cast to unsigned long.
16571 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16572 that always fit in int. Use a sentinel instead of a counter, to
16573 avoid a temp and to allay GCC's concerns about possible int overflow.
16574 * frame.h (struct frame): Use int for menu_bar_items_used
16575 instead of EMACS_INT, since it always fits in int.
16577 * menu.c (grow_menu_items): Check for int overflow.
16579 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16581 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16582 Before, the code was not consistent. These values cannot exceed
16583 2**31 - 1 so there's no need to make them unsigned.
16584 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16585 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16586 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16588 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16590 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16591 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16592 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16593 presumably because the widths might not match.
16595 * window.c (size_window): Avoid needless test at loop start.
16597 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16599 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16601 2011-05-12 Drew Adams <drew.adams@oracle.com>
16603 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16605 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16607 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16608 `width' to `bar_area_x' and `bar_area_width', respectively.
16609 (x_scroll_run): Take account of fringe background extension.
16611 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16612 Rename local vars `left' and `width' to `bar_area_x' and
16613 `bar_area_width', respectively.
16614 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16615 background extension.
16617 2011-05-10 Jim Meyering <meyering@redhat.com>
16619 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16621 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16623 * image.c (Finit_image_library): Return t for built-in image types,
16624 like pbm and xbm. (Bug#8640)
16626 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16628 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16630 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16632 * w32console.c (Fset_screen_color): Doc fix.
16633 (Fget_screen_color): New function.
16634 (syms_of_ntterm): Defsubr it.
16636 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16637 unlink the temporary file if Fcall_process didn't create it in the
16639 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16640 child process will be redirected to a file specified with `:file'.
16641 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16642 cue to call_process_cleanup not to close that handle.
16644 2011-05-07 Ben Key <bkey76@gmail.com>
16646 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16647 one of two shell specific rules, either bootstrap-temacs-CMD or
16648 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16649 to the previous implementation of the bootstrap-temacs rule.
16650 The bootstrap-temacs-CMD rule is similar to the previous
16651 implementation of the bootstrap-temacs rule except that it
16652 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16655 These changes, along with some changes to nt/configure.bat,
16656 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16657 earlier fix to add support for --cflags and --ldflags options
16658 that include quotes so that it works whether make uses cmd or
16661 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16663 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16664 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16666 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16667 a string. Handle both cases.
16668 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16669 (Fdbus_register_method): Use Qinvalid_function.
16671 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16673 * makefile.w32-in: Update dependencies.
16674 (LISP_H): Add inttypes.h and stdin.h.
16675 (PROCESS_H): Add unistd.h.
16677 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16679 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16680 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16682 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16684 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16686 * term.c (vfatal): Remove stray call to va_end.
16687 It's not needed and the C Standard doesn't allow it here anyway.
16689 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16690 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16692 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16695 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16697 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16699 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16701 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16703 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16705 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16706 * charset.c (Fdefine_charset_internal): Don't initialize
16707 charset.code_space[15]. The value was garbage, on hosts with
16708 32-bit int (Bug#8600).
16710 * lread.c (read_integer): Be more consistent with string-to-number.
16711 Use string_to_number to do the actual conversion; this avoids
16712 rounding errors and fixes some other screwups. Without this fix,
16713 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16714 (digit_to_number): Move earlier, for benefit of read_integer.
16715 Return -1 if the digit is out of range for the base, -2 if it is
16716 not a digit in any supported base. (Bug#8602)
16718 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16720 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16721 to match comment at start of function. This also removes a
16722 GCC warning about overflow in a 32+64-bit port.
16724 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16726 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16727 Reported by Stefan Monnier in
16728 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16729 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16730 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16732 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16733 (EMACS_UINTPTR): Likewise, with uintptr_t.
16735 * lisp.h: Prefer 64-bit EMACS_INT if available.
16736 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16737 on 32-bit hosts that have 64-bit int, so that they can access
16739 However, temporarily disable this change unless the temporary
16740 symbol WIDE_EMACS_INT is defined.
16742 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16744 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16745 This removes an assumption that EMACS_INT and long are the same
16746 width as pointers. The assumption is true for Emacs porting targets
16747 now, but we want to make other targets possible.
16748 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16749 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16750 In the rest of the code, change types of integers that hold casted
16751 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16752 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16753 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16754 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16755 No need to cast type when ORing.
16756 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16757 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16758 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16759 assume EMACS_INT is the same width as char *.
16760 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16761 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16762 Remove no-longer-needed casts.
16763 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16764 (xg_tool_bar_help_callback, xg_make_tool_item):
16765 Use EMACS_INTPTR to hold an integer
16766 that will be cast to void *; this can avoid a GCC warning
16767 if EMACS_INT is not the same width as void *.
16768 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16769 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16770 (current_message_1, set_message_1):
16771 Use a local to convert to proper width without a cast.
16772 * xmenu.c (dialog_selection_callback): Likewise.
16774 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16775 Also, don't assume VALBITS / RAND_BITS is less than 5,
16776 and don't rely on undefined behavior when shifting a 1 left into
16778 * lisp.h (get_random): Change signature to match.
16780 * lread.c (hash_string): Use size_t, not int, for hash computation.
16781 Normally we prefer signed values; but hashing is special, because
16782 it's better to use unsigned division on hash table sizes so that
16783 the remainder is nonnegative. Also, size_t is the natural width
16784 for hashing into memory. The previous code used 'int', which doesn't
16785 retain enough info to hash well into very large tables.
16786 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16788 * dbusbind.c: Don't possibly lose pointer info when converting.
16789 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16790 Use XPNTR rather than XHASH, so that the high-order bits of
16791 the pointer aren't lost when converting through void *.
16793 * eval.c (Fautoload): Don't double-shift a pointer.
16795 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16797 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16799 * gnutls.c (DEF_GNUTLS_FN):
16800 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16802 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16804 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16807 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16809 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16810 New version that can reserve upto 2GB of heap space.
16812 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16814 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16816 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16818 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16819 `gnutls_certificate_set_x509_key_file'.
16821 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16823 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16824 Update dependencies.
16826 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16828 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16829 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16830 Remove unused parameter `fildes'.
16831 * process.c (read_process_output, send_process): Don't pass it.
16833 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16835 Fix previous change: the library cache is defined in w32.c.
16836 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16837 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16839 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16841 Implement dynamic loading of GnuTLS on Windows.
16843 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16844 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16845 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16848 * gnutls.c (Qgnutls_dll): Define.
16849 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
16850 (gnutls_*): Declare function pointers.
16851 (init_gnutls_functions): New function to initialize function pointers.
16852 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
16853 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
16854 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16855 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
16856 (emacs_gnutls_write, emacs_gnutls_read)
16857 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
16858 (Fgnutls_available_p): New function.
16859 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
16860 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
16861 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
16863 * image.c: Include w32.h.
16864 (Vimage_type_cache): Delete.
16865 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
16866 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
16867 (w32_delayed_load): Move to w32.c.
16869 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
16871 * w32.c (QCloaded_from, Vlibrary_cache): Define.
16872 (w32_delayed_load): Move from image.c. When loading a library, record
16873 its filename in the :loaded-from property of the library id.
16874 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
16875 Initialize and staticpro them.
16876 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
16878 * process.c: Include lisp.h before w32.h, not after.
16879 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16880 instead of gnutls_record_check_pending.
16882 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16884 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16886 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16887 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16890 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16892 * xterm.c (x_set_frame_alpha): Do not set property on anything
16893 else than FRAME_X_OUTER_WINDOW (Bug#8608).
16895 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16897 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
16899 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16901 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
16902 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

16908 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
16909 (Qgnutls_bootprop_callbacks_verify): Make static.
16911 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
16913 * callproc.c: Indentation fixup.
16915 * sysdep.c (wait_for_termination_1): Make static.
16916 (wait_for_termination, interruptible_wait_for_termination):
16917 Move after wait_for_termination_1.
16919 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
16921 * sysdep.c (interruptible_wait_for_termination): New function
16922 which is like wait_for_termination, but allows keyboard
16925 * callproc.c (Fcall_process): Add (:file "file") as an option for
16927 (Fcall_process_region): Ditto.
16929 2011-04-30 Eli Zaretskii <eliz@gnu.org>
16931 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
16932 rather than `XVECTOR (FOO)->size'.
16934 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16935 inttypes.h, as a gnulib replacement is used if it not available in
16938 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16940 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16941 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16942 of MOST_POSITIVE_FIXNUM. (Bug#8528)
16944 * coding.c (coding_alloc_by_realloc): Error out if destination
16945 will grow beyond MOST_POSITIVE_FIXNUM.
16946 (decode_coding_emacs_mule): Abort if there isn't enough place in
16947 charbuf for the composition carryover bytes. Reserve an extra
16948 space for up to 2 characters produced in a loop.
16949 (decode_coding_iso_2022): Abort if there isn't enough place in
16950 charbuf for the composition carryover bytes.
16952 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16954 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
16955 aborting when %lld or %lll format is passed.
16956 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16957 %llo or %llx format is passed. (Bug#8545)
16959 * window.c (window_scroll_line_based): Use a marker instead of
16960 simple variables to record original value of point. (Bug#7952)
16962 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16963 produced by %s or %c overflows available buffer space. (Bug#8545)
16965 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16967 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16968 (SIZE_MAX): Move defn after all includes, as they might #define it.
16970 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16972 * w32.c (init_environment): Warn about defaulting HOME to C:\.
16974 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16976 * keyboard.c (Qdelayed_warnings_hook): Define.
16977 (command_loop_1): Run `delayed-warnings-hook'
16978 if Vdelayed_warnings_list is non-nil.
16979 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16980 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16982 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16984 * doprnt.c (doprnt): Don't return value smaller than the buffer
16985 size if the message was truncated. (Bug#8545).
16987 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16989 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16990 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16992 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16994 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
16996 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
16998 * makefile.w32-in: Update dependencies.
17000 2011-04-27 Eli Zaretskii <eliz@gnu.org>
17002 Improve `doprnt' and its usage. (Bug#8545)
17003 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17004 `format_end'. Remove support for %l as a conversion specifier.
17005 Don't use xrealloc. Improve diagnostics when the %l size modifier
17006 is used. Update the commentary.
17008 * eval.c (verror): Simplify calculation of size_t.
17010 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17013 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17015 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17018 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17020 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17021 This makes this file independent of the recent pseudovector change.
17023 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17025 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17027 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17028 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17029 Remove unused local.
17030 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17032 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17033 GCC 4.6.0 optimizes based on type-based alias analysis.
17034 For example, if b is of type struct buffer * and v of type struct
17035 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17036 != &v->size, and therefore "v->size = 1; b->size = 2; return
17037 v->size;" must therefore return 1. This assumption is incorrect
17038 for Emacs, since it type-puns struct Lisp_Vector * with many other
17039 types. To fix this problem, this patch adds a new type struct
17040 vectorlike_header that documents the constraints on layout of vectors
17041 and pseudovectors, and helps optimizing compilers not get fooled
17042 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17043 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17044 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17046 (XSETPVECTYPE): Rewrite in terms of new macro.
17047 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17048 This is a bit clearer, and further avoids the possibility of
17049 undesirable aliasing.
17050 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17051 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17052 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17053 since Lisp_Subr is a special case (no "next" field).
17054 (ASIZE): Now uses header.size rather than size.
17055 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17056 to avoid the hassle of writing XVECTOR (foo)->header.size.
17057 (struct vectorlike_header): New type.
17058 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17059 object, to help avoid aliasing.
17060 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17061 (SUBRP): Likewise, since Lisp_Subr is a special case.
17062 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17063 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17064 (struct Lisp_Hash_Table): Combine first two members into a single
17065 struct vectorlike_header member. All uses of "size" and "next" members
17066 changed to be "header.size" and "header.next".
17067 * buffer.h (struct buffer): Likewise.
17068 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17069 * frame.h (struct frame): Likewise.
17070 * process.h (struct Lisp_Process): Likewise.
17071 * termhooks.h (struct terminal): Likewise.
17072 * window.c (struct save_window_data, struct saved_window): Likewise.
17073 * window.h (struct window): Likewise.
17074 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17075 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17076 * buffer.c (init_buffer_once): Likewise.
17077 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17079 * process.c (Fformat_network_address): Use local var for size,
17082 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17084 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17085 * data.c (atof): Remove decl; no longer used or needed.
17086 (digit_to_number): Move to lread.c.
17087 (Fstring_to_number): Use new string_to_number function, to be
17088 consistent with how the Lisp reader treats infinities and NaNs.
17089 Do not assume that floating-point numbers represent EMACS_INT
17090 without losing information; this is not true on most 64-bit hosts.
17091 Avoid double-rounding errors, by insisting on integers when
17092 parsing non-base-10 numbers, as the documentation specifies.
17093 * lisp.h (string_to_number): New decl, replacing ...
17094 (isfloat_string): Remove.
17095 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17096 (read1): Do not accept +. and -. as integers; this
17097 appears to have been a coding error. Similarly, do not accept
17098 strings like +-1e0 as floating point numbers. Do not report
17099 overflow for integer overflows unless the base is not 10 which
17100 means we have no simple and reliable way to continue.
17101 Break out the floating-point parsing into a new
17102 function string_to_number, so that Fstring_to_number parses
17103 floating point numbers consistently with the Lisp reader.
17104 (digit_to_number): Move here from data.c. Make it static inline.
17105 (E_CHAR, EXP_INT): Remove, replacing with ...
17106 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17107 (string_to_number): New function, replacing isfloat_string.
17108 This function checks for valid syntax and produces the resulting
17109 Lisp float number too. Rework it so that string-to-number
17110 no longer mishandles examples like "1.0e+". Use strtoumax,
17111 so that overflow for non-base-10 numbers is reported only when
17112 there's no portable and simple way to convert to floating point.
17114 * textprop.c (set_text_properties_1): Rewrite for clarity,
17115 and to avoid GCC warning about integer overflow.
17117 * intervals.h (struct interval): Use EMACS_INT for members
17118 where EMACS_UINT might cause problems. See
17119 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17120 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17121 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17123 (offset_intervals): Tell GCC not to worry about length overflow
17124 when negating a negative length.
17126 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17127 (overrun_check_free): Likewise.
17129 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17130 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17133 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17134 (gnutls_make_error): Rename local to avoid shadowing.
17135 (gnutls_emacs_global_deinit): ifdef out; not used.
17136 (Fgnutls_boot): Use const for pointer to readonly storage.
17137 Comment out unused local. Fix pointer signedness problems.
17139 * lread.c (openp): Don't stuff size_t into an 'int'.
17140 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17141 about possible signed overflow.
17143 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17144 (GDK_KEY_g): Don't define if already defined.
17145 (xg_prepare_tooltip): Avoid pointer signedness problem.
17146 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17148 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17149 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17151 * xfns.c (Fx_window_property): Simplify a bit,
17152 to make a bit faster and to avoid GCC 4.6.0 warning.
17153 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17155 * fns.c (internal_equal): Don't assume size_t fits in int.
17157 * alloc.c (compact_small_strings): Tighten assertion a little.
17159 Replace pEd with more-general pI, and fix some printf arg casts.
17160 * lisp.h (pI): New macro, generalizing old pEd macro to other
17161 conversion specifiers. For example, use "...%"pI"d..." rather
17162 than "...%"pEd"...".
17163 (pEd): Remove. All uses replaced with similar uses of pI.
17164 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17165 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17166 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17167 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17168 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17169 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17170 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17172 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17173 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17174 * print.c (safe_debug_print, print_object): Likewise.
17175 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17177 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17178 avoiding the 0 flag, which is not portable.
17179 * process.c (Fmake_network_process): Use pI to avoid cast.
17180 * region-cache.c (pp_cache): Likewise.
17181 * xdisp.c (decode_mode_spec): Likewise.
17182 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17183 behavior on 64-bit hosts with printf arg.
17184 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17185 (x_stop_queuing_selection_requests): Likewise.
17186 (x_get_window_property): Don't truncate byte count to an 'int'
17189 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17190 here, since it parses constructs like leading '-' and spaces,
17191 which are not wanted; and it overflows with large numbers.
17192 Instead, simply match F[0-9]+, which is what is wanted anyway.
17194 * alloc.c: Remove unportable assumptions about struct layout.
17195 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17196 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17197 (allocate_vectorlike, make_pure_vector): Use the new macros,
17198 plus offsetof, to remove unportable assumptions about struct layout.
17199 These assumptions hold on all porting targets that I know of, but
17200 they are not guaranteed, they're easy to remove, and removing them
17201 makes further changes easier.
17203 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17204 This doesn't fix a bug but makes the code clearer.
17205 (string_overrun_cookie): Now const. Use initializers that
17206 don't formally overflow signed char, to avoid warnings.
17207 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17208 can cause Emacs to crash when string overrun checking is enabled.
17209 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17210 multiple of sizeof (EMACS_INT); it need not be, if
17211 alignof(EMACS_INT) < sizeof (EMACS_INT).
17212 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17214 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17218 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
17220 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
17221 supposed to be handshaking. (Bug#8556)
17222 Reported by Paul Eggert <eggert@cs.ucla.edu>.
17224 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
17226 * lisp.h (Qdebug): List symbol.
17227 * eval.c (Qdebug): Restore global linkage.

17229 (handle_user_signal): Break into debugger when debug-on-event
17230 matches the current signal symbol.
17232 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
17234 * alloc.c (check_sblock, check_string_bytes)
17235 (check_string_free_list): Convert to standard C.
17237 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
17239 * w32.c (emacs_gnutls_push): Fix typo.
17241 2011-04-25 Eli Zaretskii <eliz@gnu.org>
17243 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17244 "cast to pointer from integer of different size".
17246 Improve doprnt and its use in verror. (Bug#8545)
17247 * doprnt.c (doprnt): Document the set of format control sequences
17248 supported by the function. Use SAFE_ALLOCA instead of always
17251 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17252 is one byte too soon. Don't use xrealloc; instead xfree and
17255 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17257 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
17260 * gnutls.c: Renamed global_initialized to
17261 gnutls_global_initialized. Added internals for the
17262 :verify-hostname-error, :verify-error, and :verify-flags
17263 parameters of `gnutls-boot' and documented those parameters in the
17264 docstring. Start callback support.
17265 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17266 unless a fatal error occurred. Call gnutls_alert_send_appropriate
17267 on error. Return error code.
17268 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
17269 (emacs_gnutls_read): Likewise.
17270 (Fgnutls_boot): Return handshake error code.
17271 (emacs_gnutls_handle_error): New function.
17272 (wsaerror_to_errno): Likewise.

17334 <char-direction-table>: Deleted.
17336 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17338 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
17339 * doprnt.c: Include limits.h.
17340 (SIZE_MAX): New macro.
17341 (doprnt): Return a size_t value. 2nd arg is now size_t.
17342 Many local variables are now size_t instead of int or unsigned.
17343 Improve overflow protection. Support `l' modifier for integer
17344 conversions. Support %l conversion. Don't assume an EMACS_INT
17345 argument for integer conversions and for %c.
17347 * lisp.h (doprnt): Restore prototype.
17349 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
17350 $(SRC)/character.h.
17352 * Makefile.in (base_obj): Add back doprnt.o.
17354 * deps.mk (doprnt.o): Add back prerequisites.
17355 (callint.o): Depend on character.h.
17357 * eval.c (internal_lisp_condition_case): Include the handler
17358 representation in the error message.
17359 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
17360 when breaking from the loop.
17362 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
17364 * callint.c (Fcall_interactively): When displaying error message
17365 about invalid control letter, pass the character's codepoint, not
17366 a pointer to its multibyte form. Improve display of the character
17367 in octal and display also its hex code.
17369 * character.c (char_string): Use %x to display the (unsigned)
17370 codepoint of an invalid character, to avoid displaying a bogus
17373 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
17374 `error', not SYMBOL_NAME itself.
17376 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
17377 character arguments to `error'.
17379 * charset.c (check_iso_charset_parameter): Fix incorrect argument
17380 to `error' in error message about FINAL_CHAR argument. Make sure
17381 FINAL_CHAR is a character, and use %c when it is passed as
17382 argument to `error'.
17384 2011-04-23 Eli Zaretskii <eliz@gnu.org>

17448 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
17449 by pacifying GCC about it. Maybe it's time to retire it?

17452 * dispextern.h (struct redisplay_interface): Rename param

17571 * nsfont.m: Fixed bugs in ns_get_family and
17572 ns_descriptor_to_entity that were caused by using free to
17573 deallocate memory blocks that were allocated by xmalloc (via
17574 xstrdup). This caused Emacs to crash when compiled with
17575 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
17576 --enable-checking=xmallocoverrun). xfree is now used to
17577 deallocate these memory blocks.

17592 Emacs source code has been audited now.
17593 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
17594 (emacs_read, emacs_write): Use it.
17595 * process.c (send_process): Adjust to the new signatures of
17596 emacs_write and emacs_gnutls_write. Do not attempt to store
17597 a byte offset into an 'int'; it might overflow.

17926 * lisp.h: Remove these decls.
17928 * buffer.c (buffer_count): Remove unused var.
17930 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
17931 so that it's not optimized away.
17932 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
17933 * dispextern.h (bidi_dump_cached_states): Remove, since it's
17934 exported only to the debugger.
17936 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
17937 * atimer.h (run_all_atimers): Remove; not exported.
17939 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
17940 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
17941 was inaccessible from Lisp.
17942 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
17943 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
17945 alloc.c: Import and export fewer symbols, and remove unused items.
17946 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
17948 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
17949 it's not optimized away by whole-program optimization.
17950 (message_enable_multibyte, free_misc): Remove.
17951 (catchlist, handlerlist, mark_backtrace):
17952 Declare only if BYTE_MARK_STACK.

17961 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
17962 (mark_backtrace): Define only if BYTE_MARK_STACK.
17963 * xdisp.c (message_enable_multibyte): Now static.
17965 Declare Lisp_Object Q* variables to be 'static' if not exported.
17966 This makes it easier for human readers (and static analyzers)
17967 to see whether these variables are used from other modules.
17968 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
17969 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
17970 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

17978 Remove decls of unexported vars.
17979 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
17981 * lisp.h (DEFINE_FUNC): Make sname 'static'.
17983 Make Emacs functions such as Fatom 'static' by default.
17984 This makes it easier for human readers (and static analyzers)
17985 to see whether these functions can be called from other modules.
17986 DEFUN now defines a static function. To make the function external
17987 so that it can be used in other C modules, use the new macro DEFUE.
17988 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
17989 (Finit_image_library):
17990 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
17991 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
17992 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
17993 Remove decls, since these functions are now static.
17994 (Funintern, Fget_internal_run_time): New decls, since these functions
17995 were already external.
17997 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
17998 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

18004 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
18005 Mark functions with DEFUE instead of DEFUN,
18006 if they are used in other modules.
18007 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18008 decls for now-static functions.
18009 * buffer.h (Fdelete_overlay): Remove decl.

18019 * image.c (Finit_image_library): New forward static decl.
18020 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
18021 * intervals.h (Fprevious_property_change):
18022 (Fremove_list_of_text_properties): Remove decls.
18023 * keyboard.c (Fthis_command_keys): Remove decl.
18024 (Fcommand_execute): New forward static decl.

18045 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18047 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18048 when at ZV. (Bug#8487)
18050 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18052 * charset.c (Fclear_charset_maps): Use xfree instead of free.

18055 * sound.c (sound_cleanup, alsa_close): Likewise.
18056 * termcap.c (tgetent): Likewise.
18057 * xfns.c (x_default_font_parameter): Likewise.
18058 * xsettings.c (read_and_apply_settings): Likewise.
18060 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18061 (overrun_check_free): Protoize.
18063 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18065 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18066 since callers should never pass a negative size.
18067 Change the signature to match that of plain 'read' and 'write'; see
18068 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18069 * lisp.h: Update prototypes of emacs_write and emacs_read.
18071 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18073 * xdisp.c (redisplay_window): Don't try to determine the character
18074 position of the scroll margin if the window start point w->startp
18075 is outside the buffer's accessible region. (Bug#8468)
18077 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18079 Fix write-region and its subroutines for buffers > 2GB.
18080 * fileio.c (a_write, e_write): Modify declaration of arguments and
18081 local variables to support buffers larger than 2GB.
18082 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18084 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18085 argument, local variables, and return value.
18087 * lisp.h: Update prototypes of emacs_write and emacs_read.
18089 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18091 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18093 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18095 Fix more problems found by GCC 4.6.0's static checks.
18097 * xdisp.c (vmessage): Use a better test for character truncation.
18099 * charset.c (load_charset_map): <, not <=, for optimization,
18100 and to avoid potential problems with integer overflow.
18101 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18102 * casetab.c (set_identity, shuffle): Likewise.
18103 * editfns.c (Fformat): Likewise.
18104 * syntax.c (skip_chars): Likewise.
18106 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18107 This also lets GCC 4.6.0 generate slightly better loop code.
18109 * callint.c (Fcall_interactively): <, not <=, for optimization.
18110 (Fcall_interactively): Count the number of arguments produced,
18111 not the number of arguments given. This is simpler and lets GCC
18112 4.6.0 generate slightly better code.
18114 * ftfont.c: Distingish more carefully between FcChar8 and char.
18115 The previous code passed unsigned char * to a functions like
18116 strlen and xstrcasecmp that expect char *, which does not
18117 conform to the C standard.
18118 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18119 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18120 char * when the C standard requires it.
18122 * keyboard.c (read_char): Remove unused var.
18124 * eval.c: Port to Windows vsnprintf (Bug#8435).
18125 Include <limits.h>.
18126 (SIZE_MAX): Define if the headers do not.
18127 (verror): Do not give up if vsnprintf returns a negative count.
18128 Instead, grow the buffer. This ports to Windows vsnprintf, which
18129 does not conform to C99. Problem reported by Eli Zaretskii.
18130 Also, simplify the allocation scheme, by avoiding the need for
18131 calling realloc, and removing the ALLOCATED variable.
18133 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18135 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18136 But keep the doprint source code for now, as we might revamp it
18137 and use it again (Bug#8435).
18138 * lisp.h (doprnt): Remove.
18139 * Makefile.in (base_obj): Remove doprnt.o.
18140 * deps.mk (doprnt.o): Remove.
18142 error: Print 32- and 64-bit integers portably (Bug#8435).
18143 Without this change, on typical 64-bit hosts error ("...%d...", N)
18144 was used to print both 32- and 64-bit integers N, which relied on
18145 undefined behavior.
18146 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18147 * lisp.h (error, verror): Mark as printf-like functions.
18148 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18149 Report overflow in size calculations when allocating printf buffer.
18150 Do not truncate output string at its first null byte.
18151 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18152 Truncate the output at a character boundary, since vsnprintf does not
18154 * charset.c (check_iso_charset_parameter): Convert internal
18155 character to string before calling 'error', since %c now has the
18157 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18158 overflow when computing char to be passed to 'error'. Do not
18159 pass Lisp_Object to 'error'; pass the integer instead.
18160 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18161 formatted with plain %d.
18163 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18165 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18167 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18169 * xterm.c (x_catch_errors): Remove duplicate declaration.
18171 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18173 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18175 2011-04-10 Jim Meyering <meyering@redhat.com>
18177 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18178 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18179 return ssize_t not "int", and use size_t as the buffer length.
18180 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18181 * gnutls.h: Update declarations.
18182 * process.c (read_process_output): Use ssize_t, to match.
18183 (send_process): Likewise.
18185 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18187 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18189 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18191 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18192 Use unsigned char, to match FcChar8 type definition.
18194 * xterm.c (handle_one_xevent):
18195 * xmenu.c (create_and_show_popup_menu):
18196 * xselect.c (x_decline_selection_request)
18197 (x_reply_selection_request): Avoid type-punned deref of X events.
18199 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18201 Fix some uses of `int' instead of EMACS_INT.
18202 * search.c (string_match_1, fast_string_match)
18203 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18204 (scan_buffer, find_next_newline_no_quit)
18205 (find_before_next_newline, search_command, Freplace_match)
18206 (Fmatch_data): Make some `int' variables be EMACS_INT.
18208 * xdisp.c (display_count_lines): 3rd argument and return value now
18209 EMACS_INT. All callers changed.
18210 (pint2hrstr): Last argument is now EMACS_INT.
18212 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18213 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18214 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

18225 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18226 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18228 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18229 (encode_invocation_designation): Last argument P_NCHARS is now
18231 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18232 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18234 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18237 * ccl.c (Fccl_execute_on_string): Declare some variables
18240 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18242 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18244 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18246 * process.c (Fformat_network_address): Doc fix.
18248 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18250 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18252 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18254 * keyboard.c (read_char): Call Lisp function help-form-show,
18255 instead of using internal_with_output_to_temp_buffer.
18256 (Qhelp_form_show): New var.
18257 (syms_of_keyboard): Use DEFSYM macro.
18259 * print.c (internal_with_output_to_temp_buffer): Function deleted.

18266 (list_processes_1): Delete.
18268 2011-04-06 Eli Zaretskii <eliz@gnu.org>
18270 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
18272 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18274 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>

18292 (tiff_load): Add casts to remove these marks before passing them
18293 to system-supplied API.
18295 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18297 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18298 This avoids several warnings with gcc -Wstrict-overflow.
18299 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18300 directly, rather than having caller test rule sign. This avoids
18301 some unnecessary tests.
18302 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18303 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18304 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18306 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18307 (xfont_open): Avoid unnecessary tests.
18309 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18311 * composite.h, composite.c (composition_gstring_put_cache):
18312 Use EMACS_INT, not int, for length.
18314 * composite.h (COMPOSITION_DECODE_REFS): New macro,
18315 breaking out part of COMPOSITION_DECODE_RULE.
18316 (COMPOSITION_DECODE_RULE): Use it.
18317 * composite.c (get_composition_id): Remove unused local vars,
18318 by using the new macro.
18320 * textprop.c (set_text_properties_1): Change while to do-while,
18321 since the condition is always true at first.
18323 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18324 (interval_deletion_adjustment): Return unsigned value.
18327 * process.c (list_processes_1, create_pty, read_process_output):
18328 (exec_sentinel): Remove vars that were set but not used.
18329 (create_pty): Remove unnecessary "volatile"s.
18330 (Fnetwork_interface_info): Avoid possibility of int overflow.
18331 (read_process_output): Do adaptive read buffering even if carryover.
18332 (read_process_output): Simplify nbytes computation if buffered.

18337 (update_syntax_table): Use unsigned instead of int.
18339 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18340 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18341 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18343 * print.c (print_error_message): Avoid int overflow.
18345 * font.c (font_list_entities): Redo for clarity,
18346 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18348 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18349 (font_score): Avoid potential overflow in diff calculation.
18351 * fns.c (substring_both): Remove var that is set but not used.
18352 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18354 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18356 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18357 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18358 can always succeed if overflow has undefined behavior.
18360 * search.c (boyer_moore, wordify): Remove vars set but not used.
18361 (wordify): Omit three unnecessary tests.
18363 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18364 All callers changed. This avoids the need for an unused var.
18366 * casefiddle.c (casify_region): Remove var that is set but not used.
18368 * dired.c (file_name_completion): Remove var that is set but not used.
18370 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18372 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18373 (Finsert_file_contents): Remove unnecessary code checking fd.
18375 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18376 Check for integer overflow on size calculations.
18378 * buffer.c (Fprevious_overlay_change): Remove var that is set
18381 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18382 Remove vars that are set but not used.
18383 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18384 (timer_check_2): Mark vars as initialized.
18386 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18388 * image.c (lookup_image): Remove var that is set but not used.
18389 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18391 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18392 that are set but not used.
18394 * xfns.c (make_invisible_cursor): Don't return garbage
18395 if XCreateBitmapFromData fails (Bug#8410).
18397 * xselect.c (x_get_local_selection, x_handle_property_notify):
18398 Remove vars that are set but not used.
18400 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18401 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
18403 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
18404 Remove var that is set but not used.
18405 (scroll_bar_windows_size): Now size_t, not int.
18406 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
18407 Check for overflow.
18409 * xfaces.c (realize_named_face): Remove vars that are set but not used.
18410 (map_tty_color) [!defined MSDOS]: Likewise.
18412 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18414 * coding.c: Remove vars that are set but not used.
18415 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18416 All callers changed.
18417 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
18418 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18419 (decode_coding_charset): Remove vars that are set but not used.
18421 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18422 that is set but not used.
18424 * print.c (print_object): Remove var that is set but not used.
18426 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18427 The gnulib version avoids calling malloc in the usual case,
18428 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18429 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18430 * filelock.c (current_lock_owner): Likewise.
18431 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18432 * sysdep.c: Include allocator.h, careadlinkat.h.
18433 (emacs_no_realloc_allocator): New static constant.
18434 (emacs_readlink): New function.
18435 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18436 ../lib/careadlinkat.h.
18438 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18440 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18441 first non-nil return value).
18443 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
18445 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
18446 if not defined (Bug#8403).
18448 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18450 * xdisp.c (display_count_lines): Remove parameter `start',
18451 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18452 (get_char_face_and_encoding): Remove parameter `multibyte_p',
18453 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

18455 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18456 and thereabouts. All callers changed.
18457 (get_per_char_metric): Remove parameter `f', unused since
18458 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
18460 2011-04-02 Jim Meyering <meyering@redhat.com>
18462 do not dereference NULL upon failed strdup
18463 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18464 (ns_get_family): Likewise.
18466 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18468 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
18470 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
18472 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
18475 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
18477 Add lexical binding.
18479 * window.c (Ftemp_output_buffer_show): New fun.
18480 (Fsave_window_excursion):
18481 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
18483 * lread.c (lisp_file_lexically_bound_p): New function.
18484 (Fload): Bind Qlexical_binding.
18485 (readevalloop): Remove `evalfun' arg.
18486 Bind Qinternal_interpreter_environment.
18487 (Feval_buffer): Bind Qlexical_binding.
18488 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
18490 (syms_of_lread): Declare `lexical-binding'.
18492 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
18494 * keyboard.c (eval_dyn): New fun.
18495 (menu_item_eval_property): Use it.
18497 * image.c (parse_image_spec): Use Ffunctionp.
18499 * fns.c (concat, mapcar1): Accept byte-code-functions.
18501 * eval.c (Fsetq): Handle lexical vars.
18502 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18503 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18504 (FletX, Flet): Obey lexical binding.
18505 (Fcommandp): Handle closures.
18506 (Feval): New `lexical' arg.
18507 (eval_sub): New function extracted from Feval. Use it almost
18508 everywhere where Feval was used. Look up vars in lexical env.
18510 (Ffunctionp): Move from subr.el.
18511 (Ffuncall): Handle closures.
18512 (apply_lambda): Remove `eval_flags'.
18513 (funcall_lambda): Handle closures and new byte-code-functions.
18514 (Fspecial_variable_p): New function.
18515 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18516 but without exporting it to Lisp.
18518 * doc.c (Fdocumentation, store_function_docstring):
18519 * data.c (Finteractive_form): Handle closures.
18521 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18524 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18526 (exec_byte_code): New function extracted from Fbyte_code to handle new
18527 calling convention for byte-code-functions. Add new byte-codes.
18529 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
18531 * alloc.c (Fmake_symbol): Init new `declared_special' field.
18533 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18535 * xdisp.c (redisplay_internal): Fix prototype.
18537 2011-03-31 Eli Zaretskii <eliz@gnu.org>
18539 * xdisp.c (SCROLL_LIMIT): New macro.
18540 (try_scrolling): Use it when setting scroll_limit.
18541 Limit scrolling to 100 screen lines.
18542 (redisplay_window): Even when falling back on "recentering",
18543 position point in the window according to scroll-conservatively,
18544 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18546 (try_scrolling): When point is above the window, allow searching
18547 as far as scroll_max, or one screenful, to compute vertical
18548 distance from PT to the scroll margin position. This prevents
18549 try_scrolling from unnecessarily failing when
18550 scroll-conservatively is set to a value slightly larger than the
18551 window height. Clean up the case of PT below the margin at bottom
18552 of window: scroll_max can no longer be INT_MAX. When aggressive
18553 scrolling is in use, don't let point enter the opposite scroll
18554 margin as result of the scroll.
18555 (syms_of_xdisp) <scroll-conservatively>: Document the
18556 threshold of 100 lines for never-recentering scrolling.
18558 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18560 * dispextern.h (move_it_by_lines):

18563 (message_log_check_duplicate): Remove parameters `prev_bol' and
18564 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18565 (redisplay_internal): Remove parameter `preserve_echo_area',
18566 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18568 * indent.c (Fvertical_motion):
18569 * window.c (window_scroll_pixel_based, Frecenter):
18570 Don't pass `need_y_p' to `move_it_by_lines'.
18572 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18574 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18575 steal a few bits to be more compact.
18576 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18577 Remove unneeded casts.
18579 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18581 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18583 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18584 binding" message (bug#7967).
18586 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18588 Fix more problems found by GCC 4.6.0's static checks.
18590 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18591 Remove unused local var.
18593 * editfns.c (Fmessage_box): Remove unused local var.
18595 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18596 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18597 Omit unused local vars.
18598 * window.c (shrink_windows): Omit unused local var.
18599 * menu.c (digest_single_submenu): Omit unused local var.
18600 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18601 Omit unused local var.
18603 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18604 Don't assume string length fits in int.
18605 (keyremap_step, read_key_sequence): Use size_t for sizes.
18606 (read_key_sequence): Don't check last_real_key_start redundantly.
18608 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18609 instead of alloca (Bug#8344).
18611 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18612 (Fbacktrace_frame): Don't assume nframes fits in int.
18614 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18616 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18619 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18621 * cm.c (calccost): Turn while-do into do-while, for clarity.
18623 * keyboard.c (syms_of_keyboard): Use the same style as later
18624 in this function when indexing through an array. This also
18625 works around GCC bug 48267.
18627 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18629 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18631 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18632 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18634 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18635 This avoids undefined behavior on integer overflow, and is a bit
18636 more convenient anyway since it is compared to a size_t variable.
18638 Variadic C functions now count arguments with size_t, not int.
18639 This avoids an unnecessary limitation on 64-bit machines, which
18640 caused (substring ...) to crash on large vectors (Bug#8344).
18641 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18642 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

18650 * fns.c (concat): Likewise.
18651 * frame.c (x_set_frame_parameters): Likewise.
18652 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18653 0 if not found, not -1. All callers changed.
18655 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18656 (stack_copy_size): Now size_t, not int.
18657 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
18659 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18661 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
18662 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18663 All callers changed.
18665 * lisp.h (multibyte_char_to_unibyte):
18666 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18667 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

18675 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18677 * keyboard.c (safe_run_hook_funcall): New function.
18678 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18679 don't set the hook to nil, but remove the offending function instead.
18680 (Qcommand_hook_internal): Remove, unused.
18681 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18682 Vcommand_hook_internal.
18684 * eval.c (enum run_hooks_condition): Remove.
18685 (funcall_nil, funcall_not): New functions.
18686 (run_hook_with_args): Call each function through a `funcall' argument.

18689 (Frun_hook_with_args_until_failure): Adjust accordingly.
18690 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

18700 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18701 All callers changed.
18703 * w32.c (_wsa_errlist): Use braces for struct initializers.
18705 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
18706 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
18707 All callers changed.

18862 * buffer.c (Fkill_all_local_variables):
18863 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18865 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18866 unconditionally since it does the check itself.
18868 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18870 Fix more problems found by GCC 4.5.2's static checks.
18872 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18873 the first time through the loop, since we know p0 < p1 then.
18874 This also avoids a gcc -Wstrict-overflow warning.
18876 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18877 leading to a memory leak, possible in functions like
18878 load_charset_map_from_file that can allocate an unbounded number
18879 of objects (Bug#8318).
18881 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18882 that could (at least in theory) be that large.
18884 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18885 This is less likely to overflow, and avoids undefined behavior if
18886 overflow does occur. All callers changed. Use strtoul to scan
18887 for the unsigned long integer.
18888 (pint2hrstr): Simplify and tune code slightly.
18889 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

18899 * fileio.c (Fcopy_file): Report error if fchown or fchmod
18902 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
18904 * process.c (Fmake_network_process): Use socklen_t, not int,
18905 where POSIX says socklen_t is required in portable programs.
18906 This fixes a porting bug on hosts like 64-bit HP-UX, where
18907 socklen_t is wider than int (Bug#8277).
18908 (Fmake_network_process, server_accept_connection):
18909 (wait_reading_process_output, read_process_output):
18912 * process.c: Rename or move locals to avoid shadowing.

18922 Make tparam.h and terminfo.c consistent.
18923 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18924 Include tparam.h instead, since it declares them.
18925 * cm.h (PC): Remove extern decl; tparam.h now does this.
18926 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18927 * terminfo.c: Include tparam.h, to check interfaces.
18928 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18929 (tparam): Adjust signature to match interface in tparam.h;
18930 this removes some undefined behavior. Check that outstring and len
18931 are zero, which they always are with Emacs.
18932 * tparam.h (PC, BC, UP): New extern decls.
18934 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18935 (xftfont_open): Rename locals to avoid shadowing.
18937 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

18949 * composite.c (composition_compute_stop_pos): Rename local to
18951 (composition_reseat_it): Remove unused locals.
18952 (find_automatic_composition, composition_adjust_point): Likewise.
18953 (composition_update_it): Mark var as initialized.
18954 (find_automatic_composition): Mark vars as initialized,
18955 with a FIXME (Bug#8290).

18959 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18960 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18961 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18962 to avoid shadowing.
18964 * textprop.c (property_change_between_p): Remove; unused.
18966 * intervals.c (interval_start_pos): Now static.
18968 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

18974 Fix pointer signedness.
18975 (alsa_choose_format): Remove unused local var.
18976 (wav_play): Initialize a variable to 0, to prevent undefined
18977 behavior (Bug#8278).
18979 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18981 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18983 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18984 clobbering (Bug#8298).
18985 * sysdep.c (sys_subshell): Likewise.
18986 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18988 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18989 This should get cleaned up, so that child_setup has the
18990 same signature on all platforms.
18992 * callproc.c (call_process_cleanup): Now static.
18993 (relocate_fd): Rename locals to avoid shadowing.
18995 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
18997 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
18998 not to be necessary, and produces flickering.
19000 2011-03-20 Glenn Morris <rgm@gnu.org>
19002 * config.in: Remove file.
19004 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
19006 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
19007 are now in src/globals.h.

19049 Define only if needed.
19051 * unexelf.c (unexec): Name an expression,
19052 to avoid gcc -Wbad-function-cast warning.
19053 Use a different way to cause a compilation error if anyone uses
19054 n rather than nn, a way that does not involve shadowing.
19055 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
19057 * deps.mk (unexalpha.o): Remove; unused.
19059 New file unexec.h, the (simple) interface for unexec (Bug#8267).

19134 ENABLE_CHECKING is not defined.
19136 * data.c (Findirect_variable): Name an expression, to avoid
19137 gcc -Wbad-function-cast warning.

19154 (Fmemory_limit): Cast sbrk's returned value to char *.

19181 (WORDCHAR_P): Likewise. This one is never needed, but is used
19182 only in a comment talking about a compiler bug, so put inside
19183 the #if 0 of that comment.
19184 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19185 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

19212 New macros, so that the caller can use some names other than
19213 gcpro1, gcpro2, etc.
19214 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19216 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19217 argument, for consistency with GCPRO2_VAR, etc: it is now the

19221 Rename locals to avoid shadowing.
19223 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

19225 dired.c's scmp function, had undefined behavior.
19226 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19227 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19228 * buffer.h: ... to here, because these macros use current_buffer,
19229 and the new implementation with inline functions needs to have
19230 current_buffer in scope now, rather than later when the macros
19232 (downcase, upcase1): New static inline functions.
19233 (DOWNCASE, UPCASE1): Reimplement using these functions.
19234 This avoids undefined behavior in expressions like
19235 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19236 from race conditions in accessing the global variables
19237 case_temp1 and case_temp2.
19238 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

19262 * marker.c (bytepos_to_charpos): Remove; unused.
19264 * lisp.h (verify_bytepos, count_markers): New decls,
19265 so that gcc does not warn that these functions aren't declared.

19268 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

19275 * buffer.c (fix_overlays_before): Mark locals as initialized.
19276 (fix_start_end_in_overlays): Likewise. This function should be
19277 simplified by using pointers-to-pointers, but that's a different

19280 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19281 (report_overlay_modification): Rename locals to avoid shadowing.

19286 to suppress a gcc -Wclobbered warning that does not seem to be right.
19287 (MAXPATHLEN): Define only if needed.
19289 * process.c (serial_open, serial_configure): Move decls from here ...
19290 * systty.h: ... to here, so that they can be checked.
19292 * fns.c (get_random, seed_random): Move extern decls from here ...
19293 * lisp.h: ... to here, so that they can be checked.
19295 * sysdep.c (reset_io): Now static.
19296 (wait_for_termination_signal): Remove; unused.
19298 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
