3 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
4 even if w32-quote-process-args is nil.
6 2013-01-27 Eli Zaretskii <eliz@gnu.org>
8 * w32.c (sys_open): Zero out the flags for the new file descriptor.
9 (sys_close): Zero out the flags for the file descriptor before
10 closing it. (Bug#13546)
12 2013-01-26 Eli Zaretskii <eliz@gnu.org>
14 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
15 (logon_network_drive, stat_worker, symlink, chase_symlinks): Use
16 CharNextExA and CharPrevExA to iterate over file names encoded in
19 2013-01-25 Eli Zaretskii <eliz@gnu.org>
21 * w32.c (w32_get_long_filename, init_environment, readlink):
22 Support file names encoded in DBCS codepages.
23 (readlink): Use the current file-name-coding-system, not the ANSI
24 codepage, to decode and handle targets of symlinks.
26 2013-01-23 Eli Zaretskii <eliz@gnu.org>
28 * w32.c (max_filename_mbslen): New function.
29 (normalize_filename, readdir): Use it to detect locales where ANSI
30 encoding of file names uses a double-byte character set (DBCS).
31 If a DBCS encoding is used, advance by characters using
32 CharNextExA, instead of incrementing a 'char *' pointer. Use
33 _mbslwr instead of _strlwr. (Bug#13515)
35 2013-01-22 Eli Zaretskii <eliz@gnu.org>
37 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
38 request of memory reservation to 1.7GB. (Bug#13065)

63 Backport typo fix from trunk, for AIX (Bug#13408).
64 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
65 This follows up on the 2012-09-29 patch that removed indirection
66 for the 'function' field. Reported by Sergey Vinokurov in
67 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
69 Fix SIGDANGER handlers, for AIX (Bug#13408).
70 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
71 Move handlers here from emacs.c; they were out of place.
73 2013-01-05 Eli Zaretskii <eliz@gnu.org>
75 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
76 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
77 digits for buffer positions, before misalignment starts. Display
78 "0" for integer "object" field.
79 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
80 Display the newline glyph more unambiguously.
82 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
84 * nsterm.m (ns_draw_underwave):
85 * w32term.c (w32_draw_underwave):
86 * xterm.c (x_draw_underwave): Make underwave look more triangular
87 and also degrade gracefully for small fonts. (Bug#13000)
89 * nsterm.m (ns_draw_text_decoration):
90 * w32term.c (x_draw_glyph_string):
91 * xterm.c (x_draw_glyph_string): Don't use previous underline
92 thickness and position if previous underline type is underwave.
94 2012-12-31 Glenn Morris <rgm@gnu.org>
96 * keymap.c (Fkey_description): Doc fix. (Bug#13323)
98 2012-12-29 Andreas Schwab <schwab@linux-m68k.org>
100 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
101 (LIBS_GNUSTEP): Define.
102 (LIBES): Add $(LIBS_GNUSTEP).
103 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
105 2012-12-27 Eli Zaretskii <eliz@gnu.org>
107 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
108 continuation glyph on a TTY with an indication of an empty line.
111 2012-12-27 Glenn Morris <rgm@gnu.org>
113 * cygw32.c (Fcygwin_convert_file_name_to_windows)
114 (Fcygwin_convert_file_name_from_windows): Doc fixes.
116 2012-12-24 Eli Zaretskii <eliz@gnu.org>
118 * fileio.c (file_name_as_directory, directory_file_name): Accept
119 an additional argument MULTIBYTE to indicate whether the input C
120 came from a multibyte or a unibyte Lisp string; all callers
121 adjusted. Don't assume the input string is always multibyte.
123 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
124 don't ENCODE_FILE them, and return a unibyte string if the input
126 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
127 don't assume the input strings will always be multibyte. If the
128 input strings are multibyte, decode strings obtained from C
131 2012-12-22 Martin Rudalics <rudalics@gmx.at>
133 * window.c (Fselect_window): Reword doc-string (Bug#13248).
135 2012-12-21 Eli Zaretskii <eliz@gnu.org>
137 * fileio.c (Finsert_file_contents): Doc fix.
139 * w32proc.c (new_child, delete_child, find_child_pid): For a
140 subprocess, consider its slot being in use as long as its process
141 handle (procinfo.hProcess) is not NULL. This avoids reusing the
142 slot when a new process is started immediately after killing
143 another one, without waiting enough time for the first process to
144 be reaped and resources allocated for it be orderly freed.
146 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
148 2012-12-21 Chong Yidong <cyd@gnu.org>

156 2012-12-14 Eli Zaretskii <eliz@gnu.org>
158 * w32.c (get_name_and_id): Always pass NULL as the first argument
159 of lookup_account_sid. Avoids crashes with UNC file names that
160 refer to DFS domains, not to specific machine names. (Bug#12621)
161 Remove now unused argument FNAME; all callers changed.
162 (get_file_owner_and_group): Remove now unused argument FNAME; all
165 2012-12-11 Eli Zaretskii <eliz@gnu.org>
167 * search.c (search_buffer): Check the inverse translations of each
168 character in pattern when the buffer being searched is unibyte.
171 2012-12-10 Paul Eggert <eggert@cs.ucla.edu>

181 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
183 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
184 DWORD_PTR, for compatibility with 64-bit builds.
186 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
187 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)
188 (system_process_attributes): Use SIZE_T rather than DWORD, for
189 compatibility with 64-bit builds.

195 2012-12-07 Eli Zaretskii <eliz@gnu.org>
197 * indent.c (Fvertical_motion): If a display string will be
198 displayed on the left or the right margin, don't consider it as a
199 factor in cursor positioning. (Bug#13108)
201 2012-12-07 Martin Rudalics <rudalics@gmx.at>
203 * editfns.c (Fcompare_buffer_substrings): Reword doc-string.
205 2012-12-05 Eli Zaretskii <eliz@gnu.org>
207 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
208 fails, signal an error instead of continuing with an empty
210 Encode expanded temp file pattern before passing it to mkstemp or
213 2012-12-04 Eli Zaretskii <eliz@gnu.org>
215 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
216 Encode the file name before passing it to dostounix_filename, in
217 case it will downcase it (under w32-downcase-file-names).
220 2012-12-01 Chong Yidong <cyd@gnu.org>
222 * fileio.c (Vauto_save_list_file_name): Doc fix.
224 2012-11-30 Fabrice Popineau <fabrice.popineau@gmail.com>
226 * w32fns.c: Remove prototype of atof.
227 (syspage_mask): Declared DWORD_PTR, for compatibility with 64-bit
229 (file_dialog_callback): Declared UINT_PTR.

247 2012-11-24 Paul Eggert <eggert@cs.ucla.edu>
249 Revert recent change for Bug#8855.
250 As reported by Harald Hanche-Olsen in
251 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00445.html>
252 the change introduces a further bug, of creating lots of zombie
253 processes in some cases. Further work is needed to come up with a
254 better fix for Bug#8855.
256 2012-11-24 Eli Zaretskii <eliz@gnu.org>
258 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
259 highlighting on the frame was cleared. Prevents assertion
260 violations when repeatedly clicking on the "Top" link of the
261 "bread-crumbs" in Info buffers.
263 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
264 Eli Zaretskii <eliz@gnu.org>
266 Fix a race condition with glib (Bug#8855).
267 The symptom is a diagnostic "GLib-WARNING **: In call to
268 g_spawn_sync(), exit status of a child process was requested but
269 SIGCHLD action was set to SIG_IGN and ECHILD was received by
270 waitpid(), so exit status can't be returned." The diagnostic
271 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
272 The real bug is a race condition between Emacs and glib: Emacs
273 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
274 so that glib can't find it. Work around the bug by invoking
275 waitpid only on subprocesses that Emacs itself creates.
277 This is a backport from the trunk, consisting of:
279 * w32proc.c (create_child): Don't clip the PID of the child
280 process to fit into an Emacs integer, as this is no longer a
282 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
283 reaping only the process specified by PID argument, if that is
284 positive. Use PID instead of dead_child to know which process to
285 reap. Wait for the child to die only if WNOHANG is not in
287 (sys_select): Don't set dead_child.
289 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
290 as it is no longer needed.
292 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
294 (create_process, record_child_status_change): Don't use special
295 value -1 in pid field, as the caller now must know the pid rather
296 than having the callee infer it. The inference was sometimes
297 incorrect anyway, due to another race.
298 (create_process): Set new 'alive' member if child is created.
299 (process_status_retrieved): New function.
300 (record_child_status_change): Use it.
301 Accept negative 1st argument, which means to wait for the
302 processes that Emacs already knows about. Move special-case code
303 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
304 processes that have already been waited for, by testing and
305 clearing new 'alive' member. Remove the setting of
306 record_at_most_one_child for the !WNOHANG case.
307 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
308 now does this internally.
309 (handle_child_signal): Let record_child_status_change do all
310 the work, since we do not want to reap all exited child processes,
311 only the child processes that Emacs itself created.
312 * process.h (Lisp_Process): New boolean member 'alive'.
314 2012-11-23 Eli Zaretskii <eliz@gnu.org>
316 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
317 between bpos_covered and bpos_max. This fixes cursor display when
318 several display strings follow each other.
320 * .gdbinit (pgx): If the glyph's object is a string, display the
321 pointer to string data, rather than the value of the string object
322 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
324 2012-11-21 Eli Zaretskii <eliz@gnu.org>
326 * indent.c (Fvertical_motion): If the starting position is covered
327 by a display string, return to one position before that, to avoid
328 overshooting it inside move_it_to. (Bug#12930)
330 2012-11-20 Daniel Colascione <dancol@dancol.org>
332 * w32fns.c (Fx_file_dialog):
333 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
334 cygwin_convert_file_name*.
336 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
337 Rename cygwin_convert_path* to cygwin_convert_file_name*.
339 2012-11-20 Ken Brown <kbrown@cornell.edu>
341 * emacs.c (main): Set the G_SLICE environment variable for all
342 Cygwin builds, not just GTK builds. See
343 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
345 2012-11-19 Eli Zaretskii <eliz@gnu.org>
347 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Don't mix declaration of
348 w32_note_current_window with code. (Backport from trunk.)
350 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
351 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
352 Define for the MSVC compiler.
354 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing
357 2012-11-18 Eli Zaretskii <eliz@gnu.org>
359 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
360 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
361 dostounix_filename. Prevents crashes down the road, because
362 dostounix_filename assumes it gets a unibyte string. Reported by
363 Michel de Ruiter <michel@sentient.nl>, see
364 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
366 2012-11-17 Eli Zaretskii <eliz@gnu.org>
368 * w32select.c: Include w32common.h before w32term.h, so that
369 windows.h gets included before w32term.h uses some of its
372 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]: New
374 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]: New
376 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
378 2012-11-17 Jan Djärv <jan.h.d@swipnet.se>
380 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
381 (ns_select): Return at once if events are held (Bug#12834).
383 2012-11-16 enami tsugutomo <tsugutomo.enami@jp.sony.com>
385 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
386 Needed following 2012-10-20 change. (Bug#12902)
388 2012-11-16 Glenn Morris <rgm@gnu.org>
390 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
392 2012-11-15 Stefan Monnier <monnier@iro.umontreal.ca>
394 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
396 2012-11-14 Eli Zaretskii <eliz@gnu.org>
398 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
399 use the same value of thread handle.
400 (start_timer_thread): If the timer thread exited (due to error),
401 clean up by closing the two handles it used. Duplicate the caller
402 thread's handle here, so it gets duplicated only once, when
403 launching the timer thread. Set priority of the timer thread, not
405 (getitimer): Don't duplicate the caller thread's handle here.
408 2012-11-13 Jan Djärv <jan.h.d@swipnet.se>
410 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
413 2012-11-12 Eli Zaretskii <eliz@gnu.org>
415 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
416 passed to pint2str and pint2hrstr to be at most the size of the
417 frame's decode_mode_spec_buffer. This avoids crashes with very
418 large values of FIELD_WIDTH argument to decode_mode_spec.
421 2012-11-07 Martin Rudalics <rudalics@gmx.at>
423 * window.c (Fsplit_window_internal): Set combination limit of
424 new parent window to t iff Vwindow_combination_limit is t;
425 fixing a regression introduced with the change from 2012-09-22.
426 (Fwindow_combination_limit, Fset_window_combination_limit):
429 2012-11-06 Eli Zaretskii <eliz@gnu.org>
431 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
432 amount when the scroll margins are too large. When scrolling
433 backwards in the buffer, give up if cannot reach point or the
434 scroll margin within a reasonable number of screen lines.
435 Fixes point position in window under scroll-up/down-aggressively when
436 point is positioned many lines beyond the window top/bottom.
439 2012-11-05 Eli Zaretskii <eliz@gnu.org>
441 * ralloc.c (relinquish): If real_morecore fails to return memory
442 to the system, don't crash; instead, leave the last heap
443 unchanged and return. (Bug#12774)
445 2012-11-03 Eli Zaretskii <eliz@gnu.org>
447 * lisp.mk: Adjust comments to the fact that term/internal is now
448 loaded from loadup.el.
450 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
451 (msdos_fatal_signal): New function.
452 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
455 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
456 for GCC versions before 4.
457 (emacs_raise): Define to call msdos_fatal_signal.
459 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
460 iterator when starting in the middle of a display or overlay
463 2012-11-03 Jan Djärv <jan.h.d@swipnet.se>

474 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
476 Fix crash when using Emacs as commit editor for git (Bug#12697).
477 * callproc.c (setpgrp): Remove macro, as we now use setpgid
478 and it is configured in conf_post.h.
479 (Fcall_process): Don't invoke both setsid and setpgid; the former
480 is enough, if it exists.
481 * callproc.c (Fcall_process, child_setup):
482 * process.c (create_process): Use setpgid.
483 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
485 * dispnew.c (init_display): Initialize the foreground group
486 if we are running a tty display.
487 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
488 * lisp.h (init_foreground_group): New decl.
489 * sysdep.c (inherited_pgroup): New static var.
490 (init_foreground_group, tcsetpgrp_without_stopping)
491 (narrow_foreground_group, widen_foreground_group): New functions.

499 2012-10-31 Martin Rudalics <rudalics@gmx.at>
501 * minibuf.c (read_minibuf): Restore current buffer since
502 choose_minibuf_frame calling Fset_frame_selected_window may
503 change it (Bug#12766).
505 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>

516 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
517 In preparation for fixing bug#12739, move these functions from
520 * coding.h, coding.c: ... to here, and compile them only when
521 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
522 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
524 2012-10-28 Eli Zaretskii <eliz@gnu.org>
526 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
527 (timer_loop, getitimer, setitimer): Use it instead of
528 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
530 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
533 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
535 * nsterm.m (NO_APPDEFINED_DATA): New define.
536 (last_appdefined_event_data): New variable
537 (last_appdefined_event): Remove.
538 (ns_select): Initialize t from last_appdefined_event_data instead
539 of [last_appdefined_event data1].
540 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
541 remove last_appdefined_event (Bug#12698).
543 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
545 * frame.c (x_set_font): Catch internal error.
547 2012-10-27 Eli Zaretskii <eliz@gnu.org>
549 Avoid overflow in w32 implementation of interval timers.
550 When possible, for ITIMER_PROF count only times the main thread
552 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
553 'volatile ULONGLONG' types. All the other data which was
554 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
555 (GetThreadTimes_Proc): New typedef.
556 (w32_get_timer_time): New function, returns a suitable time value
558 (timer_loop): Enter critical section when accessing ULONGLONG
559 values of the itimer_data struct, as these accesses are no longer
560 atomic. Call 'w32_get_timer_time' instead of 'clock'.
561 Remove unused variable.
562 (init_timers): Initialize s_pfn_Get_Thread_Times.
563 (start_timer_thread): Don't assign itimer->caller_thread here.
564 (getitimer): Assign itimer->caller_thread here.

568 2012-10-26 Eli Zaretskii <eliz@gnu.org>
570 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
571 mouse movement events if the menu bar is active. This avoids
572 producing a busy "hour-glass" cursor by Windows if the mouse
573 pointer is positioned over a tooltip shown for some menu item.
575 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
577 Don't assume process IDs fit in int.
578 * emacs.c (shut_down_emacs) [!DOS_NT]:
579 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
580 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
581 Use pid_t, not int, to store process IDs, as 'int'
582 is not wide enough on a few platforms (e.g., AIX and IRIX).
584 2012-10-23 Kenichi Handa <handa@gnu.org>
586 The following change is to make face-font-rescale-alist work

590 (font_open_for_lface): Handle Vface_font_rescale_alist.
592 2012-10-23 Chong Yidong <cyd@gnu.org>

609 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
612 * frame.c (Fmouse_position, Fmouse_pixel_position):
613 * xdisp.c (produce_stretch_glyph):
614 Declare local vars only when they're needed.
615 This is clearer and avoids a warning on OpenBSD about unused vars.
616 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
617 This is safer, and avoids OpenBSD warnings about unused vars.
618 * keyboard.c (record_menu_key): Remove unnecessary decl.
619 (poll_timer): Define only if POLL_FOR_INPUT is defined.
620 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
621 as our definition clashes with OpenBSD's.
622 * xfaces.c (load_face_colors, check_lface_attrs)
623 (get_lface_attributes_no_remap, get_lface_attributes)
624 (lface_fully_specified_p, x_supports_face_attributes_p)
625 (tty_supports_face_attributes_p, face_fontset, realize_face)
626 (realize_x_face, realize_tty_face):
627 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
628 merely Lisp_Object *. This is more informative and avoids
629 a warning on OpenBSD about accessing beyond an object's size.
631 2012-10-20 Chong Yidong <cyd@gnu.org>
633 * lread.c (Fload): Doc fix (Bug#12592).

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

978 * xdisp.c (start_hourglass): Call w32_note_current_window when
979 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
980 build that caused Emacs to display the hourglass cursor forever.
982 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
983 which is broken under remote desktop, calculate the number of
984 colors available for a display based on the display's number of
985 planes and number of bits per pixel per plane. (bug#10397).

1018 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
1020 (x_to_w32_color): Don't modify the argument, modify a copy instead.
1022 2012-10-08 Daniel Colascione <dancol@dancol.org>
1024 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
1025 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
1026 accidental message numbering hole. Change other messages to
1029 * w32select.h (HAVE_W32SELECT): Remove.
1031 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
1032 w32common.h instead of w32heap.h.
1034 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
1035 (get_allocation_unit, get_processor_type, get_w32_major_version)
1036 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1037 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1038 (OS_NT, os_subtype, cache_system_info): Move declarations to
1041 * w32heap.c: Include w32common.h.
1042 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
1043 (w32_minor_version, w32_build_number, w32_subtype):
1044 Remove duplicate definitions.
1046 * w32fns.c: Include w32common.h; include w32heap.h only in
1049 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
1050 Use `report_file_error' instead of `error' in order to better
1051 inform users of what went wrong. Increase NTGUI_UNICODE file
1052 dialog box file name length to 32k, the maximum allowed by the NT
1055 * w32common.h: New file.
1056 (ROUND_UP, ROUND_DOWN, get_page_size)
1057 (get_allocation_unit, get_processor_type, get_w32_major_version)
1058 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
1059 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
1060 (OS_NT, os_subtype, cache_system_info): Move here.
1062 * unexw32.c, unexcw.c: Include w32common.h.
1064 * emacs.c (main): Use (defined (WINDOWSNT) || defined
1065 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
1066 to call syms_of_w32select.
1068 * cygw32.h: Remove obsolete EXFUN declarations.
1070 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
1072 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
1073 of w32inevt.o from SOME_MACHINE_OBJECTS.
1075 2012-10-08 Daniel Colascione <dancol@dancol.org>
1077 * image.c: Permanent fix for JPEG compilation issue --- limit
1078 jpeglib `boolean' redefinition to Cygwin builds.
1080 2012-10-08 Eli Zaretskii <eliz@gnu.org>
1082 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
1084 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
1087 2012-10-08 Daniel Colascione <dancol@dancol.org>
1089 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
1090 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
1091 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
1092 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
1093 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
1094 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
1095 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
1096 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
1097 now a supported configuration.
1099 * Makefile.in: consolidate image variables into LIBIMAGE; add
1100 W32_OBJ and W32_LIBS. Compile new files.
1103 (_DebPrint) declare tracing facility for W32 debugging. We need
1104 to unify tracing later.
1106 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
1107 unconditional use of W32 Unicode functions. Cygwin runs only on
1108 100% Unicode operating systems.
1110 * cygw32.c: New file. Define Cygwin-specific facilities.
1111 (Fcygwin_convert_path_to_windows)
1112 (Fcygwin_convert_path_from_windows): New user functions for
1113 accessing Cygwin path-munging routines.
1115 * cygw32.h: New file.
1116 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
1117 UTF-16LE strings temporarily inside non-Lisp-visible string
1120 (w32_strerror): Just what it says on the tin.
1122 * emacs.c: Make the NS fork-then-exec code for daemon-launching
1123 also run for Cygwin; both systems have the same problem with using
1124 GUI facilities in a forked child. Also call syms_of_cygw32,
1125 syms_of_w32select in correct places.
1127 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
1128 needs fork-then-exec for daemon launching.
1130 * font.h: Include frame.h.
1132 * image.c: Use the image library cache machinery only when we're
1133 compiling for native WINDOWSNT; Cygwin can use shared libraries
1134 like any other Unixlike system.
1136 * keyboard.c: Clarify a comment regarding the input loop.
1138 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
1139 functions directly instead of trying to detect at runtime that our
1140 host operating system supports them. We make this change for two
1141 reasons: Cygwin lacks support for the multibyte character
1142 conversion functions used by the legacy menu code, and Cygwin
1143 never needs to rely on non-Unicode APIs.
1145 * unexw32.c (hinst): Declare extern.
1147 * w32.c: Change header order;
1148 (w32_strerror): Move to w32fns.c because we need it for
1149 non-WINDOWSNT builds.
1151 * w32.h: Add #error macro to make sure we don't include w32.h for
1152 Cygwin builds. Remove w32select declarations.
1154 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
1155 w32fns.c. w32console.c is WINDOWSNT-only.
1157 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
1158 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
1160 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
1161 (w32_major_version, w32_minor_version, w32_build_number)
1162 (os_subtype, sound_type): Define here
1163 (w32_defined_color): Make color parameter const for consistency
1164 with other _defined_color functions.
1165 (w32_createwindow): Unconditionally call w32_init_class instead of
1166 doing so only when hprevinst is non-NULL. Plumbing hprevinst
1167 through the code is complex and unnecessary because class
1168 registration is practically free.
1169 (w32_name_of_message): New EMACSDEBUG-only function.
1170 (Fset_message_beep): Move here
1171 (Fx_open_connection): Require that the display name for Windows be
1172 "w32" for consistency, emacsclient disambiguation, and maybe, one
1173 day, multi-window-system support.
1174 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
1175 Cygwin files for W32 GUI facilities, since these clearly don't
1176 expect Cygwin names.
1177 (_DebPrint): Define.
1178 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
1179 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
1180 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
1181 (w32_last_error): Remove.
1183 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
1185 * w32heap.c (syspage_mask): Declare here.
1186 (cache_system_info): Remove.
1188 * w32inevt.c (faked_key): Define globally, not statically.
1189 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
1190 (w32_console_toggle_lock_key): Move to w32fns.c.
1192 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
1194 * w32proc.c (_DebPrint): Move to w32fns.c.
1195 * w32select.c: Include string.h, stdio.h for Cygwin.
1196 * w32select.h: New File.
1198 * w32term.c: Include io.h for non-CYGWIN builds; needed for
1200 (w32_message_fd): New variable. Under Cygwin, holds the file
1201 descriptor the system used to tell us about pending thread
1204 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
1205 that prevented compilation under non-WINDOWSNT systems.
1207 (w32_initialize): Open /dev/windows and assign it to
1208 w32_message_fd. Provide w32 feature.
1210 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
1211 (WM_EMACS_INPUT_READY): add.
1212 (prepend_msg, w32_message_fd): Declare globally.
1215 (keyboard_handle): Use only when WINDOWSNT.
1216 (notify_msg_ready): New function. Posts a message to the main
1217 thread's message queue under CYGWIN, which wakes up the main
1218 thread from select(2) by making the /dev/windows file descriptor
1219 ready. Under WINDOWSNT, it sets an event the same way the old
1222 (post, prepend_msg): Actually call notify_msg_ready instead of
1223 setting the input event directly.
1225 2012-10-07 Eli Zaretskii <eliz@gnu.org>
1227 * ralloc.c (relinquish): If a heap is ready to be relinquished,
1228 but it still has blocs in it, don't return it to the system,
1229 instead of aborting. (Bug#12402)
1231 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
1233 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
1235 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
1236 MAC_OS_X_VERSION_10_6.
1237 (syms_of_nsterm): Remove comment about Panther and above for
1239 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
1240 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
1241 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
1243 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
1244 MAC_OS_X_VERSION_10_4.
1246 * nsmenu.m (fillWithWidgetValue:): Remove code for <
1247 MAC_OS_X_VERSION_10_2.
1249 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
1251 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
1252 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
1254 * nsterm.m (ns_in_resize): Remove (Bug#12479).
1255 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
1256 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
1257 Remove ns_in_resize check.
1258 (ns_clear_frame_area): Remove resize handle code.
1260 * nsfns.m (ns_in_resize): Remove.
1261 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
1262 Remove ns_in_resize check.
1264 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
1266 Improve sys_siglist detection.
1267 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
1268 defined as a macro, as is done in Solaris.
1269 (sys_siglist_entries): New macro.
1270 (save_strsignal): Use it.
1271 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
1272 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
1274 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
1276 * nsfns.m (Fx_create_frame): Call x_default_parameter with
1277 fullscreen/Fullscreen.
1279 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
1280 tobar_height is new.
1282 * nsterm.m (x_make_frame_visible): Check for fullscreen.
1283 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
1284 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
1285 (windowDidResize:): Check for correct window if old style fullscreen.
1286 Capitalize word in comment. Remove incorrect comment.
1287 (initFrameFromEmacs:): tbar_height renamed tibar_height.
1288 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
1289 error in drawing background.
1290 (toggleFullScreen:): Remove comment. Rearrange calls.
1291 Set toolbar values to zero, save old height in tobar_height.
1292 Restore tool bar height when leaving fullscreen.
1293 (canBecomeMainWindow): New function.
1295 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
1297 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
1299 2012-10-05 Eli Zaretskii <eliz@gnu.org>
1301 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
1303 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
1304 that time stamps of directories could also be changed.
1305 Don't request the too broad GENERIC_WRITE, only the more restrictive
1306 FILE_WRITE_ATTRIBUTES access rights.
1308 * fileio.c (Fset_file_times): Special-case ignoring errors for
1309 directories only on MSDOS, not on MS-Windows.
1311 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
1313 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
1315 2012-10-04 Eli Zaretskii <eliz@gnu.org>
1317 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
1318 see whether CreateFile failed.
1320 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
1322 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
1323 to avoid similar races.
1324 * keyboard.c (pending_signals): Now bool, not int.
1326 Port timers to OpenBSD, plus check for timer failures.
1327 OpenBSD problem reported by Han Boetes.
1328 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
1330 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
1331 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
1332 like OpenBSD, which has timer_settime but does not declare it.
1333 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
1334 whether to use itimerspec-related primitives. All uses of
1335 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
1337 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1339 * profiler.c (handle_profiler_signal): Fix a malloc race
1340 that caused Emacs to hang on Fedora 17 when profiling Lisp.
1342 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
1344 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
1346 2012-10-02 Eli Zaretskii <eliz@gnu.org>
1348 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
1349 consistent with the change in return value of 'safe_strsignal'.
1351 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
1353 Prefer plain 'static' to 'static inline' (Bug#12541).
1354 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
1355 (bidi_set_sor_type, bidi_push_embedding_level)
1356 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
1357 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
1358 (bidi_cache_search, bidi_cache_ensure_space)
1359 (bidi_cache_iterator_state, bidi_cache_find)
1360 (bidi_peek_at_next_level, bidi_set_paragraph_end)
1361 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
1362 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
1363 Now 'static', not 'static inline'.
1365 Count overruns when profiling; change units to ns.
1366 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
1367 Give extra weight to samples after overruns, to attempt to count
1368 the time more accurately.
1369 (setup_cpu_timer): Change sampling interval units from ms to ns, since
1370 the underlying primitives nominally do ns.
1371 (Fprofiler_cpu_start): Document the change. Mention that
1372 the sampling intervals are only approximate.
1374 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1376 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
1378 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
1379 case for the special 0 coding-system.
1381 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
1382 (Fmake_overlay): Remove redundant tests.
1383 (fix_start_end_in_overlays): Remove redundant recentering.
1385 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
1387 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
1388 Update dependencies.
1390 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1392 Fix a malloc race condition involving strsignal.
1393 A signal can arrive in the middle of a malloc, and Emacs's signal
1394 handler can invoke strsignal, which can invoke malloc, which is
1395 not portable. This race condition bug makes Emacs hang on GNU/Linux.
1396 Fix it by altering the signal handler so that it does not invoke
1398 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
1399 * process.c (status_message): Use const pointer, in case strsignal
1400 is #defined to safe_strsignal.
1401 * sysdep.c (sys_siglist, init_signals): Always define and
1402 initialize a substitute sys_siglist if the system does not define
1403 one, even if HAVE_STRSIGNAL.
1404 (safe_strsignal): Rename from strsignal. Always define,
1405 using sys_siglist. Return a const pointer.
1406 * syssignal.h (safe_strsignal): New decl.
1407 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
1409 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1411 * w32proc.c (timer_loop): Fix code that waits for timer
1412 expiration, to avoid high CPU usage.
1414 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
1416 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
1417 (sweep_weak_table): Remove redundant prototypes.
1419 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
1421 * emacs.c: Move the inclusion of TERM_HEADER after including
1422 windows.h on WINDOWSNT. This avoids compilation problems with
1425 2012-10-01 Eli Zaretskii <eliz@gnu.org>
1427 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
1428 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
1429 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
1430 as the previous version used 'void *'.
1432 * ralloc.c (ROUNDUP): Fix last change.
1433 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
1436 * w32proc.c <disable_itimers>: New static flag.
1437 (init_timers): Initialize it to zero, after creating the critical
1438 sections used by the timer threads.
1439 (term_timers): Set to 1 before deleting the critical sections.
1440 (getitimer, setitimer): If disable_itimers is non-zero, return an
1441 error indication without doing anything. Reported by Fabrice
1442 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
1443 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
1445 [!HAVE_SETITIMER]: Behave as the previous version that didn't
1448 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
1449 term_ntproc after all the other bookkeeping, to get timers working
1450 as long as possible.
1452 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
1454 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
1455 Suggested by Juri Linkov in
1456 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
1458 Prefer plain 'static' to 'static inline' (Bug#12541).
1459 With static functions, modern compilers inline pretty well by
1460 themselves; advice from programmers often hurts as much as it helps.
1461 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
1462 this change shrinks the text size of the Emacs executable by 1.1%
1463 without affecting CPU significantly in my benchmark.
1464 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
1465 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)
1466 (mark_maybe_object, mark_maybe_pointer, bounded_number):
1467 * buffer.c (bset_abbrev_mode, bset_abbrev_table)
1468 (bset_auto_fill_function, bset_auto_save_file_format)
1469 (bset_auto_save_file_name, bset_backed_up, bset_begv_marker)

1762 for consistency with other handlers.
1763 (setup_cpu_timer): New function, with much of what used to be in

1765 Prefer timer_settime if available, and prefer
1766 thread cputime clocks, then process cputime clocks, then
1767 monotonic clocks, to the old realtime clock. Use make_timeval
1768 to round more-correctly when falling back to setitimer.
1769 (Fprofiler_cpu_start): Use it.
1770 (Fprofiler_cpu_stop): Prefer timer_settime if available.

1835 * charset.c, charset.h (maybe_unify_char): Now static.
1836 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
1837 Since this stuff is now private to charset.c, there's no need for
1838 a public macro and no need to inline by hand.

1912 (sys_kill): Improve commentary.
1914 * w32.c (term_ntproc): Accept (and ignore) one argument, for
1915 consistency with a signature of a signal handler. All callers
1917 (init_ntproc): Accept an argument DUMPING. If dumping, don't
1918 install term_ntproc as a signal handler for SIGABRT, as that
1919 should be done by the dumped Emacs.

1924 invocation by setting clipboard_owner to NULL after calling

1948 now return bool, not int. All uses changed.
1949 * image.c: Omit unnecessary static decls.
1950 (x_create_bitmap_mask, x_build_heuristic_mask):
1951 Return void, not int, since callers don't care about the return value.

1986 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
1988 Move pid_t related decls out of lisp.h.
1989 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
1990 (interruptible_wait_for_termination):
1991 Move these decls from lisp.h to syswait.h, since they use pid_t.
1992 Needed on FreeBSD; see Herbert J. Skuhra in
1993 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
1994 * callproc.c: Include syswait.h.

2014 Use bool for boolean.
2015 * gtkutil.c (xg_update_frame_menubar):

2040 2012-09-23 Eli Zaretskii <eliz@gnu.org>
2042 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
2043 fatal_error_backtrace.
2045 * w32proc.c (sys_kill): Undo last change: don't do anything when
2046 invoked to deliver SIGABRT to our own process. This is now
2047 handled by emacs_raise.
2049 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
2051 * w32term.c (w32_read_socket): Remove leftover reference to
2052 interrupt_input_pending.
2054 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2056 Do not use SA_NODEFER.
2057 Problem reported by Dani Moncayo in
2058 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
2060 * sysdep.c (emacs_abort): Do not reset signal handler.
2061 * emacs.c (terminate_due_to_signal): Reset signal handler here.
2062 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
2063 wanted even on POSIXish hosts, and it doesn't work on Windows.
2065 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2067 * xterm.c (x_term_init): Call fixup_locale before and after calling
2068 gtk_init (Bug#12392).
2070 2012-09-23 Chong Yidong <cyd@gnu.org>
2072 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
2073 Vdynamic_library_alist.
2075 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
2076 (Fgnutls_available_p): Caller changed.
2078 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
2079 (Flibxml_parse_xml_region): Likewise.
2081 * dispextern.h (struct image_type): Remove arg from init function.
2083 * image.c (Finit_image_library, lookup_image_type)
2084 (define_image_type): Remove now-unneeded second arg.
2085 (init_xpm_functions, init_png_functions, init_jpeg_functions)
2086 (init_tiff_functions, init_gif_functions, init_svg_functions):
2087 Arglist and w32_delayed_load calling convention changed.
2088 (gs_type): Remove init_gs_functions; there is no such function.
2089 (valid_image_p, make_image): Fix caller to lookup_image_type.
2091 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
2093 Simplify and avoid signal-handling races (Bug#12471).
2095 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
2096 Avoid recursive loop if there's a fatal error in the function itself.
2097 * atimer.c (pending_atimers):
2098 * blockinput.h: Don't include "atimer.h"; no longer needed.
2099 (interrupt_input_pending): Remove. All uses removed.
2100 pending_signals now counts both atimers and ordinary interrupts.
2101 This is less racy than having three separate pending-signal flags.
2102 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
2104 Rename from their upper-case counterparts BLOCK_INPUT,
2105 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
2106 INPUT_BLOCKED_P, and turn into functions. All uses changed.
2107 This makes it easier to access volatile variables more accurately.
2108 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
2109 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
2110 that's more reliable if the code is buggy and sets
2111 interrupt_input_blocked to a negative value. All uses changed.
2112 * atimer.c (deliver_alarm_signal):
2113 Remove. No need to deliver this to the parent; any thread can
2114 handle this signal now. All uses replaced by underlying handler.
2115 * atimer.c (turn_on_atimers):
2116 * dispnew.c (handle_window_change_signal):
2117 * emacs.c (handle_danger_signal):
2118 * keyboard.c (kbd_buffer_get_event):
2119 Don't reestablish signal handler; not needed with sigaction.
2120 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
2122 Rework to avoid unnecessary accesses to volatile variables.
2123 (UNBLOCK_INPUT_TO): Now a function.
2124 (totally_unblock_input, unblock_input): New decls.
2125 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
2126 (init_data): Remove. Necessary stuff now done in init_signal.
2127 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
2128 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
2129 (fatal_error_code): Remove; no longer needed.
2130 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
2131 it doesn't always backtrace. All uses changed. No need to reset
2132 signal to default, since sigaction and/or die does that for us now.
2133 Use emacs_raise (FOO), not kill (getpid (), FOO).
2134 (main): Check more-accurately whether we're dumping.
2135 Move fatal-error setup to sysdep.c
2136 * floatfns.c: Do not include "syssignal.h"; no longer needed.
2137 * gtkutil.c (xg_get_file_name, xg_get_font):
2138 Remove no-longer-needed signal-mask manipulation.
2139 * keyboard.c, process.c (POLL_FOR_INPUT):
2140 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
2141 * keyboard.c (read_avail_input): Remove.
2142 All uses replaced by gobble_input.
2143 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
2144 (kbd_buffer_store_event_hold, gobble_input):
2145 (record_asynch_buffer_change) [USABLE_SIGIO]:
2146 (store_user_signal_events):
2147 No need to mess with signal mask.
2148 (gobble_input): If blocking input and there are terminals, simply
2149 set pending_signals to 1 and return. All hooks changed to not
2150 worry about whether input is blocked.
2151 (process_pending_signals): Clear pending_signals before processing
2152 them, in case a signal comes in while we're processing.
2153 By convention callers now test pending_signals before calling us.
2154 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
2155 New functions, to support changes to blockinput.h.
2156 (handle_input_available_signal): Now extern.
2157 (reinvoke_input_signal): Remove. All uses replaced by
2159 (quit_count): Now volatile, since a signal handler uses it.
2160 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
2161 All callers changed. Block SIGINT only if not already blocked.
2162 Clear sigmask reliably, even if Fsignal returns, which it can.
2163 Omit unnecessary accesses to volatile var.
2164 (quit_throw_to_read_char): No need to restore sigmask.
2165 * keyboard.c (gobble_input, handle_user_signal):
2166 * process.c (wait_reading_process_output):
2167 Call signal-handling code rather than killing ourselves.
2168 * lisp.h: Include <float.h>, for...
2169 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
2170 (pending_signals): Now volatile.
2171 (syms_of_data): Now const if IEEE floating point.
2172 (handle_input_available_signal) [USABLE_SIGIO]:
2173 (terminate_due_to_signal, record_child_status_change): New decls.
2174 * process.c (create_process): Avoid disaster if memory is exhausted
2175 while we're processing a vfork, by tightening the critical section
2177 (send_process_frame, process_sent_to, handle_pipe_signal)
2178 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
2180 (send_process): No need for setjmp/longjmp any more, since the
2181 SIGPIPE stuff is now gone. Instead, report an error if errno
2183 (record_child_status_change): Now extern. PID and W are now args.
2184 Return void, not bool. All callers changed.
2185 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
2186 Remove. All uses removed. This bug should be fixed now in a
2188 (wait_for_termination_1): Use waitpid rather than sigsuspend,
2189 and record the child status change directly. This avoids the
2190 need to futz with the signal mask.
2191 (process_fatal_action): Move here from emacs.c.
2192 (emacs_sigaction_flags): New function, containing
2193 much of what used to be in emacs_sigaction_init.
2194 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
2195 caught by emacs, to make races less likely.
2196 (deliver_process_signal): Rename from handle_on_main_thread.
2198 (BACKTRACE_LIMIT_MAX): Now at top level.
2199 (thread_backtrace_buffer, threadback_backtrace_pointers):
2201 (deliver_thread_signal, deliver_fatal_thread_signal):
2202 New functions, for more-accurate delivery of thread-specific signals.
2203 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
2204 (deliver_arith_signal): Handle in this thread, not
2205 in the main thread, since it's triggered by this thread.
2206 (maybe_fatal_sig): New function.
2207 (init_signals): New arg DUMPING so that we can be more accurate
2208 about whether we're dumping. Caller changed.
2209 Treat thread-specific signals differently from process-general signals.
2210 Block all signals while handling fatal error; that's safer.
2211 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
2213 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
2214 Ignore SIGPIPE unless batch.
2215 (emacs_backtrace): Output backtrace for the appropriate thread,
2216 which is not necessarily the main thread.
2217 * syssignal.h: Include <stdbool.h>.
2218 (emacs_raise): New macro.
2219 * xterm.c (x_connection_signal): Remove; no longer needed
2220 now that we use sigaction.
2221 (x_connection_closed): No need to mess with sigmask now.
2222 (x_initialize): No need to reset SIGPIPE handler here, since
2223 init_signals does this for us now.
2225 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
2227 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
2228 background rect may be larger (Bug#12245).
2230 2012-09-23 Chong Yidong <cyd@gnu.org>
2232 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
2234 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2236 * .gdbinit: Just stop at fatal_error_backtrace.
2237 See Stefan Monnier's request in
2238 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
2239 Remove no-longer-used query of system type.
2241 2012-09-22 Chong Yidong <cyd@gnu.org>
2243 * search.c (Freplace_match): Doc fix (Bug#12325).
2245 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
2247 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
2248 (Fline_end_position): Doc fix.
2250 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).

2254 * dispextern.h (struct image_type): Add new slot, storing a type
2255 initialization function.
2257 * image.c (define_image_type): Call the image initializer function
2258 if it is defined. Arguments and return value changed.
2259 (valid_image_p, make_image): Callers changed.
2260 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
2261 (gif_type, imagemagick_type, svg_type, gs_type):
2262 Add initialization functions.
2263 (Finit_image_library): Call lookup_image_type.
2264 (CHECK_LIB_AVAILABLE): Macro deleted.
2265 (lookup_image_type): Call define_image_type here, rather than via
2266 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
2267 (syms_of_image): Move define_image_type calls for xbm_type and
2268 pbm_type to lookup_image_type.
2270 2012-09-22 Eli Zaretskii <eliz@gnu.org>
2272 * keyboard.c (timer_check_2): Move calculation of 'timers' and
2273 'idle_timers' from here ...
2274 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
2275 lists, to avoid infloops when the timer does something stupid,
2276 like reinvoke itself with the same or smaller time-out.
2279 2012-09-22 Martin Rudalics <rudalics@gmx.at>
2281 * window.c (Fsplit_window_internal): Handle only Qt value of
2282 Vwindow_combination_limit separately.
2283 (Qtemp_buffer_resize): New symbol.
2284 (Vwindow_combination_limit): New default value.
2287 2012-09-22 Eli Zaretskii <eliz@gnu.org>

2290 the new overlay string. (Bug#10159)
2292 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
2294 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
2295 or that fprintf is async-signal-safe. POSIX doesn't require
2298 2012-09-22 Chong Yidong <cyd@gnu.org>
2300 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
2303 2012-09-22 Kenichi Handa <handa@gnu.org>
2305 * composite.c (composition_reseat_it): Handle the case that a
2306 grapheme cluster is not covered by a single font (Bug#12352).
2308 2012-09-21 Chong Yidong <cyd@gnu.org>
2310 * image.c (define_image_type): Avoid adding duplicate types to
2311 image_types (Bug#12463). Suggested by Jörg Walter.
2313 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2315 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
2316 (print_load_command_name): Add case LC_DATA_IN_CODE.
2317 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

2321 * eval.c (Frun_hook_with_args_until_success)
2322 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
2324 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
2326 * fileio.c (Ffile_selinux_context): Only call freecon when
2327 lgetfilecon succeeded.
2328 (Fset_file_selinux_context): Likewise. (Bug#12444)
2330 2012-09-21 Eli Zaretskii <eliz@gnu.org>
2332 * xdisp.c (try_window_reusing_current_matrix): Under bidi
2333 reordering, locate the cursor by calling set_cursor_from_row; if
2334 that fails, clear the desired glyph matrix before returning a
2335 failure indication to the caller. Fixes leaving garbled display
2336 when fast scrolling with a down-key. (Bug#12403)
2337 (compute_stop_pos_backwards): Fix a typo that caused crashes while
2338 scrolling through multibyte text.
2340 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
2342 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
2343 calling mark_vectorlike since that's the one that marks the window.
2344 (mark_discard_killed_buffers): Mark the final cdr.
2345 * window.h (struct window): Move prev/next_buffers to the
2346 non-standard fields.
2347 * window.c (make_window): Initialize prev/next_buffers manually.
2349 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
2351 Omit unused arg EXPECTED from socket hooks.
2352 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
2353 * nsterm.m (ns_term_init):
2354 * termhooks.h (struct terminal.read_socket_hook):
2355 * w32inevt.c (w32_console_read_socket):
2356 * w32term.c (w32_read_socket):
2357 * xterm.c (XTread_socket):
2358 Omit unused arg EXPECTED. All callers changed.
2359 (store_user_signal_events): Return void, not int, since callers no
2360 longer care about the return value. All uses changed.
2362 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
2364 * w32gui.h (XParseGeometry): Do not declare.
2366 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
2368 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
2369 Ignore 'expected'. See Eli Zaretskii in
2370 <http://bugs.gnu.org/12471#8> (last line).
2372 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
2373 (XParseGeometry): Now static. Substitute extremal values for
2374 values that are out of range.
2376 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
2378 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
2380 * nsfns.m (XParseGeometry): Remove.
2381 (Fx_create_frame): Call x_set_offset to correctly interpret
2382 top_pos in geometry.
2384 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
2385 (Fx_parse_geometry): If there is a space in string, call
2386 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
2388 2012-09-17 Eli Zaretskii <eliz@gnu.org>
2390 * search.c (scan_buffer): Use character positions in calls to
2391 region_cache_forward and region_cache_backward, not byte
2392 positions. (Bug#12196)
2394 * w32term.c (w32_read_socket): Set pending_signals to 1, like
2395 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
2397 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
2398 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
2399 emacs_blocked_malloc, now deleted.
2401 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
2403 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
2404 The workaround was for improving performance on Solaris 2.4, but
2405 is getting in the way now. Emacs will still work if someone is
2406 still running Solaris 2.4 in a museum somewhere; Sun dropped
2407 support for Solaris 2.4 in 2003.
2408 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
2409 * process.c (create_process) [HAVE_WORKING_VFORK]:
2410 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
2411 since Emacs no longer uses vfork on that platform.
2413 2012-09-17 Glenn Morris <rgm@gnu.org>
2415 * emacs.c: Use COPYRIGHT.
2417 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
2419 Remove configure's --without-sync-input option (Bug#12450).
2420 When auditing signal-handling in preparation for cleaning it up,
2421 I found that SYNC_INPUT has race conditions and would be a real
2422 pain to fix. Since it's an undocumented and deprecated
2423 configure-time option, now seems like a good time to remove it.
2424 Also see <http://bugs.gnu.org/11080#16>.
2425 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
2426 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
2427 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2428 (malloc_hysteresis):
2429 (check_depth) [XMALLOC_OVERRUN_CHECK]:
2430 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
2431 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
2432 (dont_register_blocks, bytes_used_when_reconsidered)
2433 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
2434 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
2435 [!SYSTEM_MALLOC && !SYNC_INPUT]:
2436 Remove. All uses removed.
2437 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
2438 implementation, one that depends on whether the new macro
2439 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
2441 * atimer.c (run_timers, handle_alarm_signal):
2442 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
2443 (handle_async_input, process_pending_signals)
2444 (handle_input_available_signal, init_keyboard):
2445 * nsterm.m (ns_read_socket):
2446 * process.c (wait_reading_process_output):
2447 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
2448 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
2450 * xterm.c (XTread_socket):
2452 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
2453 * eval.c (handling_signal): Remove. All uses removed.
2454 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
2455 All uses replaced with the SYNC_INPUT version.
2456 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
2458 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
2461 * font.c (Ffont_shape_gstring): Remove unused local.
2463 2012-09-16 Glenn Morris <rgm@gnu.org>
2465 * Makefile.in (clean): No longer run nextstep's clean.
2467 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
2469 (ns-app): Move here from ns.mk, and simplify.
2470 (clean): Simplify nextstep entry.
2471 * ns.mk: Remove file.
2473 2012-09-17 Kenichi Handa <handa@gnu.org>
2475 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
2476 not covert the last few charactes.
2478 2012-09-16 Kenichi Handa <handa@gnu.org>
2480 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
2481 here, but just check the validity of glyphs in the glyph-string.
2483 2012-09-16 Martin Rudalics <rudalics@gmx.at>
2485 * window.c (Fwindow_parameter, Fset_window_parameter):
2486 Accept any window as argument (Bug#12452).
2488 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
2490 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
2491 to ns_term_init to avoid memory leak.
2493 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
2494 explicit retain/release.
2495 (ns_term_init): Only allow one display. Initialize outerpool and
2498 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2500 Port _setjmp fix to POSIXish hosts as well as Microsoft.
2501 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
2502 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
2503 the Microsoft problem in a different way, by altering ../nt/config.nt.
2505 2012-09-15 Eli Zaretskii <eliz@gnu.org>
2520 * w16select.c: Remove inclusion of setjmp.h, as it is now included
2521 by lisp.h. This completes removal of setjmp.h inclusion
2522 erroneously announced in the previous commit. (Bug#12446)
2524 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
2527 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
2528 not defined as a macro. The latter happens on MS-Windows.
2531 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
2533 Port better to POSIX hosts lacking _setjmp (Bug#12446).
2534 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
2535 Some instances of '#include <setjmp.h>' removed, if the
2536 only reason for the instance was because "lisp.h" was included.
2537 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
2538 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
2539 and _longjmp with the new symbols. Emacs already uses _setjmp if
2540 available, so this change affects only POSIXish hosts that have
2541 sigsetjmp but not _setjmp, such as some versions of Solaris and
2542 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
2543 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
2544 (png_load_body) [HAVE_PNG]:
2545 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
2546 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
2547 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
2548 since PNG requires jmp_buf. This is the only exception to the
2549 general rule that we now use sys_setjmp and sys_longjmp.
2550 This exception is OK since this code does not change the signal
2551 mask or longjmp out of a signal handler.
2553 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
2555 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
2556 Include "syssignal.h", for 'main_thread'.
2558 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
2560 Avoid out-of-range marker position (Bug#12426).
2561 * insdel.c (replace_range, replace_range_2):
2562 Adjust markers before overlays, as suggested by comments.
2563 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
2564 Remove redundant check before calling offset_intervals.
2566 2012-09-14 Martin Rudalics <rudalics@gmx.at>
2568 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
2569 current buffer (Bug#12387).
2571 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
2573 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
2575 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2577 Use a more backwards-compatible timer format (Bug#12430).
2578 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
2579 vector element, not from the 4th, since PSECS is now at the end.
2580 (Fcurrent_idle_time): Doc fix.
2582 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
2584 Function to mark objects and remove killed buffers at once.
2585 * alloc.c (discard_killed_buffers): Rename to ...
2586 (mark_discard_killed buffers) ... new name. Add marking
2587 of remaining objects. Fix comment. Adjust users.
2588 (mark_object): Do not touch frame buffer lists here.
2589 * frame.c (delete_frame): Reset frame buffer lists here.
2591 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
2593 Better workaround for GNOME bug when --enable-gcc-warnings.
2594 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
2595 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
2596 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
2598 Simplify SIGIO usage (Bug#12408).
2599 The code that dealt with SIGIO was crufty and confusing, e.g., it
2600 played tricks like "#undef SIGIO" but these tricks were not used
2601 consistently. Simplify mostly by not #undeffing standard symbols,
2602 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
2603 or not as we please) rather than "defined SIGIO" (standard symbol
2604 that we probably shouldn't #undef).
2605 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
2606 Modules that need it can include it.
2607 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
2608 * dispextern.h (ignore_sigio): New decl.
2609 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
2610 unconditionally, since it's now a no-op if !USABLE_SIGIO.
2611 * emacs.c (shut_down_emacs):
2612 * keyboard.c (kbd_buffer_store_event_hold):
2613 Use ignore_sigio rather than invoking 'signal' directly.
2614 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
2616 (FIONREAD, SIGIO): Do not #undef.
2617 (tty_read_avail_input): Use #error rather than a syntax error.
2618 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
2619 for I_PIPE, used by SETUP_SLAVE_PTY.
2620 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
2621 * sysdep.c (croak): Remove; no longer needed. This bit of
2622 temporary code, with Fred N. Fish's comment that it's temporary,
2623 has been in Emacs since at least 1992!
2624 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
2625 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
2626 * syssignal.h (croak): Remove decl.
2627 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
2628 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
2629 now that we're termios-only.
2630 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
2631 * term.c (dissociate_if_controlling_tty): Use #error rather than
2634 Work around GCC and GNOME bugs when --enable-gcc-warnings.
2635 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
2636 to work around GNOME bug 683906.
2637 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
2638 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
2639 This works around GCC bug 54561.
2641 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2643 More fixes for 'volatile' and setjmp/longjmp.
2644 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
2645 * image.c (struct png_load_context) [HAVE_PNG]: New type.
2646 (png_load_body) [HAVE_PNG]:
2647 (jpeg_load_body) [HAVE_JPEG]:
2648 New function, with most of the old parent function's body.
2649 (png_load) [HAVE_PNG]:
2650 (jpeg_load) [HAVE_JPEG]:
2651 Invoke the new function, to avoid longjmp munging our locals.
2652 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
2653 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
2654 longjmp is passed 2, as the C standard doesn't guarantee this.
2655 Instead, store the failure code into mgr->failure_code.
2657 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2659 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
2660 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
2661 (syms_of_keyboard): Remove support for unread-command-char.
2663 2012-09-12 Eli Zaretskii <eliz@gnu.org>
2665 * w32proc.c (sys_kill): If PID is our process ID and the signal is
2666 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
2667 violation. (Bug#12426)
2669 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
2671 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
2673 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
2675 * eval.c: Add `inhibit-debugger'.
2676 (Qinhibit_debugger): New symbol.
2677 (call_debugger): Bind it instead of Qdebug_on_error.
2678 (maybe_call_debugger): Test Vinhibit_debugger.
2679 (syms_of_eval): Define inhibit-debugger.
2680 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
2681 (syms_of_xdisp): Remove inhibit-debug-on-message.
2683 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2685 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
2686 If a nonvolatile local variable is written before a _longjmp to
2687 the frame containing the variable, and is read after the _longjmp,
2688 the value read is indeterminate. Some local variables of type
2689 'struct handler' and 'struct catchtag' are used in this way, so
2690 mark each of their slots as volatile if the slot can be set before
2691 _longjmp and read afterwards.
2692 * lisp.h (struct handler): var and chosen_clause are now volatile.
2693 (struct catchtag): val, next, and pdlcount are now volatile.
2695 * bidi.c (bidi_push_it, bidi_pop_it):
2696 * fns.c (copy_hash_table):
2697 * image.c (define_image_type):
2698 * keyboard.c (kbd_buffer_store_event_hold):
2699 * process.c (Fprocess_send_eof):
2700 * xfaces.c (x_create_gc) [HAVE_NS]:
2701 * xgselect.c (xg_select):
2702 Prefer assignment to memcpy when either will do.
2704 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
2705 Use pointer-to-a-pointer to simplify and avoid a NILP check each
2706 time an item is removed. No need to mark this function 'inline';
2707 the compiler knows better than we do.
2709 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
2711 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
2712 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
2713 to change_frame_size (Bug#12388).
2714 (windowDidResize:): Pass YES to updateFrameSize.
2716 * nsterm.h: Add delay parameter to updateFrameSize.
2718 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2720 Discard killed buffers from deleted window and frame objects.
2721 This reduces an amount of references to killed buffers and
2722 helps GC to reclaim them faster.
2723 * alloc.c (discard_killed_buffers): New function.
2724 (mark_object): Use it for deleted windows and frames.
2725 (mark_object): If symbol's value is set up for a killed buffer
2726 or deleted frame, restore its global binding.
2727 * data.c (swap_in_global_binding): Add GC notice.
2728 (swap_in_symval_forwarding): Use convenient set_blv_where.
2729 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
2730 * window.h: ... to here.
2732 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
2734 Convenient macro to check whether the buffer is live.
2735 * buffer.h (BUFFER_LIVE_P): New macro.
2736 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
2737 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
2739 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2741 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
2742 composition cases (Bug#12364).
2744 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
2745 overhang of succeeding glyphs overlapping box cursor.
2747 * w32term.c (x_draw_glyph_string): Likewise.
2749 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
2751 Simplify, document, and port floating-point (Bug#12381).
2752 The porting part of this patch fixes bugs on non-IEEE platforms
2753 with frexp, ldexp, logb.
2754 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
2756 * floatfns.c: Simplify discussion of functions that Emacs doesn't
2757 support, by removing commented-out code and briefly listing the
2758 C89 functions excluded. The commented-out stuff was confusing
2759 maintenance, e.g., we thought we needed cbrt but it was commented out.
2760 (logb): Remove decl; no longer needed.
2761 (isfinite): New macro, if not already supplied.
2762 (isnan): Don't replace any existing macro.
2763 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
2764 are present on all C89 platforms.
2765 (Ffrexp): Do not special-case zero, as frexp does the right thing
2767 (Flogb): Do not use logb, as it doesn't have the desired meaning
2768 on hosts that use non-base-2 floating point. Instead, stick with
2769 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
2770 frexp, to avoid getting an unspecified result.
2772 * xdisp.c (Qinhibit_debug_on_message): Now static.
2774 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
2776 * nsterm.m (ns_update_begin): Set clip path to whole view by using
2777 NSBezierPath (Bug#12131).
2779 2012-09-10 Chong Yidong <cyd@gnu.org>
2781 * fns.c (Fdelq, Fdelete): Doc fix.
2783 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
2785 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
2786 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
2788 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
2790 * lisp.h (make_lisp_ptr): New macro to replace XSET.
2791 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
2794 2012-09-09 Eli Zaretskii <eliz@gnu.org>
2796 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
2797 left fringe if the window has a left margin. This avoids leaving
2798 traces of the cursor because its leftmost pixel is not drawn over.
2800 * dispnew.c (update_window_line): When the left margin area of a
2801 screen line is updated, set the redraw_fringe_bitmaps_p flag of
2802 that screen line. (Bug#12277)
2804 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
2806 Assume C89 or later for math functions (Bug#12381).
2807 This simplifies the code, and makes it a bit smaller and faster,
2808 and (most important) makes it easier to clean up signal handling
2809 since we can stop worring about floating-point exceptions in
2810 library code. That was a problem before C89, but the problem
2811 went away many years ago on all practical Emacs targets.
2812 * data.c, image.c, lread.c, print.c:
2813 Don't include <math.h>; no longer needed.
2814 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
2815 might be autoconfigured, as that never happens.
2817 * doprnt.c (DBL_MAX_10_EXP):
2818 * print.c (DBL_DIG):
2819 Remove. C89 or later always defines these.
2820 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
2821 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
2822 (arith_error, domain_error, domain_error2):
2823 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
2824 no longer needed -- we simply return what C returns. All uses removed.
2825 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
2827 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
2828 Remove. All uses expanded, as these macros are no longer used
2829 more than once and are now more trouble than they're worth.
2830 (Ftan): Use tan, not sin / cos.
2831 (Flogb): Assume C89 frexp.
2832 (fmod_float): Assume C89 fmod.
2833 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
2834 (init_floatfns): Remove. All uses removed.
2836 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2838 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
2839 compositeToPoint for OSX < 10.6 (Bug#12390).
2841 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
2843 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
2844 This produces more-accurate results.
2846 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2848 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
2849 changes (Bug#12088).
2851 2012-09-08 Chong Yidong <cyd@gnu.org>
2853 * syntax.c (Fstring_to_syntax): Doc fix.
2855 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
2857 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
2858 in the internal border.
2859 (x_set_window_size): Remove static variables and their usage.
2860 (ns_redraw_scroll_bars): Fix NSTRACE arg.
2861 (ns_after_update_window_line, ns_draw_fringe_bitmap):
2862 Remove fringe/internal border adjustment (Bug#11052).
2863 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
2864 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
2865 (ns_fix_rect_ibw): Remove.
2866 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
2867 (ns_dumpglyphs_box_or_relief): Ditto.
2868 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
2870 (ns_dumpglyphs_image): Ditto.
2871 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
2873 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
2874 their usage. Add fringe_extended_p and its use as in other terms.
2875 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
2876 scroll bar was removed.
2877 (updateFrameSize): New function.
2878 (windowDidResize): Move code to updateFrameSize and call it.
2880 * nsterm.h (EmacsView): Add updateFrameSize.
2882 2012-09-07 Chong Yidong <cyd@gnu.org>
2884 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
2886 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
2888 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2890 More signal-handler cleanup (Bug#12327).
2891 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
2892 Problem introduced when merging patches. Noted by Eli Zaretskii in
2893 <http://bugs.gnu.org/12327#67>.
2894 * floatfns.c: Comment fix.
2895 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
2896 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
2897 and anyway the declaration is harmless even if SIGDANGER is not defined.
2898 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
2899 defined BROKEN_FIONREAD). systty.h formerly did this, but other
2900 source files not surprisingly expected syssignal.h to define, or
2901 not define, SIGIO, and it's cleaner to do it that way, for consistency.
2902 Include <sys/ioctl.h>, for FIONREAD.
2903 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
2904 This eliminates a problem whereby other files mysteriously had
2905 to include "syssignal.h" before including "systty.h" if they
2906 wanted to use "#ifdef SIGIO".
2908 2012-09-07 Eli Zaretskii <eliz@gnu.org>
2910 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
2912 * w32.c (sigemptyset): Empty the set.
2913 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
2915 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
2917 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
2919 * alloc.c (mark_buffer): Revert unsafe marking optimization.
2920 (mark_object): Likewise for frame objects.
2922 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
2924 * syssignal.h (handle_on_main_thread): Always declare,
2925 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
2926 This ports to platforms without HAVE_PTHREAD.
2928 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
2930 Signal-handler cleanup (Bug#12327).
2931 Emacs's signal handlers were written in the old 4.2BSD style with
2932 sigblock and sigmask and so forth, and this led to some
2933 inefficiencies and confusion. Rewrite these to use
2934 pthread_sigmask etc. without copying signal sets around. Also,
2935 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
2936 'signal', and instead use functions that do not attempt to take
2937 over the system name space. This patch causes Emacs's text
2938 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
2939 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
2940 Do not include <signal.h> or "syssignal.h", as these
2941 modules do not use signals.
2942 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
2943 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
2944 Do not include <signal.h>, as "syssignal.h" does that for us now.
2945 * atimer.c (sigmask_atimers): New function.
2946 (block_atimers, unblock_atimers): New functions,
2947 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
2949 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
2950 no longer needed here.
2951 * emacs.c (main): Inspect existing signal handler with sigaction,
2952 so that there's no need to block and unblock SIGHUP.
2953 * sysdep.c (struct save_signal): New member 'action', replacing
2954 old member 'handler'.
2955 (save_signal_handlers, restore_signal_handlers):
2956 Use sigaction instead of 'signal' to save and restore.
2957 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
2958 New function. All users of 'signal' modified to use set_sighandler
2959 if they're writeonly, and to use sys_signal if they're read+write.
2960 (emacs_sigaction_init, forwarded_signal): New functions.
2961 (sys_signal): Remove. All uses replaced by calls to sigaction
2962 and emacs_sigaction_init, or by direct calls to 'signal'.
2963 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
2964 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
2965 all uses replaced by pthread_sigmask etc. calls.
2966 * syssignal.h: Include <signal.h>.
2967 (emacs_sigaction_init, forwarded_signal): New decls.
2968 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
2969 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
2970 (sigmask, sys_sigmask): Remove; no longer needed.
2971 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
2972 (sigblock, sigunblock, sigfree):
2973 (sigsetmask) [!defined sigsetmask]:
2974 Remove. All uses replaced by pthread_sigmask.
2975 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
2976 no longer need to be replaced, and its typical old uses
2977 are now done via emacs_sigaction_init and sigaction.
2978 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
2979 (sys_sigdel): Remove; unused.
2980 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
2982 2012-09-06 Eli Zaretskii <eliz@gnu.org>
2984 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
2985 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
2987 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
2989 Explicitly mark buffer_defaults and buffer_local_symbols.
2990 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
2991 mark_local_symbols here.
2992 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
2993 since special buffers aren't marked here any more.
2994 (allocate_buffer): Chain new buffer with all_buffers here...
2995 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
2997 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
2998 (syms_of_buffer): Remove staticpro of the above.
2999 (init_buffer_once): Set names for buffer_defaults and
3000 buffer_local_symbols.
3002 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
3004 Use bool for booleans in font-related modules.
3005 * font.c (font_intern_prop, font_style_to_value)
3006 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
3007 (generate_otf_features, font_check_otf_features, font_check_otf)
3008 (font_match_p, font_list_entities, font_at):
3009 * fontset.c (fontset_id_valid_p, reorder_font_vector
3010 (fontset_find_font, Fset_fontset_font)
3011 (face_suitable_for_char_p) [0]:
3012 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
3013 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
3014 (m17n_flt_initialized, ftfont_shape_by_flt):
3015 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
3016 * nsfont.m (nsfont_draw):
3017 * w32font.c (w32font_draw):
3018 * w32term.c (x_draw_glyphless_glyph_string_foreground):
3019 Use bool for booleans.
3020 * font.h: Adjust to above API changes.
3021 (struct font, struct font_driver, struct font_driver_list):
3022 Use bool for booleans.
3023 (struct font): Remove useless member encoding_type.
3025 * fontset.c, xftfont.c: Omit unnecessary static decls.
3027 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
3029 * alloc.c (mark_object): Revert window marking code
3030 since it's unsafe for the Fset_window_configuration.
3032 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3034 Fix race conditions with signal handlers and errno (Bug#12327).
3035 Be more systematic about preserving errno whenever a signal
3036 handler returns, even if it's not in the main thread. Do this by
3037 renaming signal handlers to distinguish between signal delivery
3038 and signal handling. All uses changed.
3039 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
3040 * data.c (deliver_arith_signal): Rename from arith_error.
3041 * dispnew.c (deliver_window_change_signal): Rename from
3042 window_change_signal.
3043 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
3044 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
3045 * keyboard.c (deliver_input_available_signal): Rename from
3046 input_available_signal.
3047 (deliver_user_signal): Rename from handle_user_signal.
3048 (deliver_interrupt_signal): Rename from interrupt_signal.
3049 * process.c (deliver_pipe_signal): Rename from send_process_trap.
3050 (deliver_child_signal): Rename from sigchld_handler.
3051 * atimer.c (handle_alarm_signal):
3052 * data.c (handle_arith_signal):
3053 * dispnew.c (handle_window_change_signal):
3054 * emacs.c (handle_fatal_signal, handle_danger_signal):
3055 * keyboard.c (handle_input_available_signal):
3056 * keyboard.c (handle_user_signal, handle_interrupt_signal):
3057 * process.c (handle_pipe_signal, handle_child_signal):
3058 New functions, with the actual signal-handling code taken from the
3059 original respective signal handlers, sans the sporadic attempts to
3060 preserve errno, since that's now done by handle_on_main_thread.
3061 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
3062 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
3063 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3065 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3066 Move initialization of main_thread to sysdep.c's init_signals.
3067 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
3068 our usage, and simplifies the mainline code.
3069 (record_child_status_change): New static function, as a helper
3070 for handle_child_signal, and with most of the old child handler's
3072 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
3073 (handle_child_signal): Use the above.
3074 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
3075 Moved here from emacs.c.
3076 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
3077 code moved here from emacs.c's main function.
3078 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
3079 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
3080 This lets callers save and restore errno properly.
3082 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3084 Remove redundant or unused things here and there.
3085 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
3086 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
3087 * editfns.c (Fcompare_buffer_substrings): Likewise.
3088 * frame.h (struct terminal, struct font_driver_list):
3089 Remove redundant declarations.
3090 * window.h (Qleft, Qright): Likewise.
3092 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3094 Do not mark objects from deleted buffers, windows and frames.
3095 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
3096 (mark_object): Likewise for windows and frames.
3098 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
3100 * alloc.c (valid_lisp_object_p): Treat killed buffers,
3101 buffer_defaults and buffer_local_symbols as valid objects.
3102 Return special value to denote them.
3104 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
3106 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
3107 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
3108 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
3109 (file_name_absolute_p, Fsubstitute_in_file_name):
3110 (check_executable, check_writable, Ffile_accessible_directory_p)
3111 (Fset_file_selinux_context, Fdefault_file_modes)
3112 (Finsert_file_contents, choose_write_coding_system)
3113 (Fwrite_region, build_annotations, a_write, e_write)
3115 * filelock.c (boot_time_initialized, get_boot_time)
3116 (get_boot_time_1, lock_file_1, within_one_second):
3117 * floatfns.c (in_float):
3118 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
3119 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
3120 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
3121 * lisp.h (struct Lisp_Hash_Table.cmpfn):
3122 * window.c (compare_window_configurations):
3123 Use bool for booleans.
3124 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
3125 (Fdefault_file_modes): Now mode_t, not int, for modes.
3126 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
3127 (internal_delete_file): Now returns void, not a (boolean) int,
3128 since nobody was looking at the return value.
3129 * lisp.h, window.h: Adjust to above API changes.
3131 * xdisp.c (set_message): Simplify and reindent last change.
3133 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
3135 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
3137 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
3139 * eval.c (call_debugger): Make the function non-static so that we
3140 can call it from set_message.
3142 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
3143 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
3145 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3147 Give more-useful info on a fatal error (Bug#12328).
3148 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
3149 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
3150 of doing the work ourselves.
3151 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
3152 do most of the work.
3153 (fatal_error_backtrace): New function, taken from the guts
3154 of the old fatal_error_signal, but with a new option to output
3156 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
3157 info about the signal than just its number.
3158 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
3159 * sysdep.c: Include <execinfo.h>
3160 (emacs_backtrace): New function, taken partly from the previous
3161 code of the 'die' function.
3162 (emacs_abort): Call fatal_error_backtrace rather than abort.
3164 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
3166 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
3167 eager (load-time) macro-expansion.
3168 * lisp.mk (lisp): Add macroexp.
3170 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3172 Simplify redefinition of 'abort' (Bug#12316).
3173 Do not try to redefine the 'abort' function. Instead, redo
3174 the code so that it calls 'emacs_abort' rather than 'abort'.
3175 This removes the need for the NO_ABORT configure-time macro
3176 and makes it easier to change the abort code to do a backtrace.
3177 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
3178 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
3179 Remove; sysdep.c's emacs_abort now takes its place.
3180 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
3181 'abort' changed to use 'emacs_abort'.
3182 * msdos.c (dos_abort) [defined abort]: Remove; not used.
3183 (abort) [!defined abort]: Rename to ...
3184 (emacs_abort): ... new name.
3185 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
3186 the place of the old 'abort' in emacs.c.
3187 * w32.c, w32fns.c (abort): Do not #undef.
3188 * w32.c (emacs_abort): Rename from w32_abort.
3190 2012-09-04 Eli Zaretskii <eliz@gnu.org>
3192 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
3193 offsets[j].dv, since the y axis of the screen coordinates points
3194 down, while the y axis of the font definition coordinates points
3195 up. This fixes display of Arabic diacritics such as KASRA and
3196 KASRATAN. (Bug#11860)
3198 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
3200 Be more systematic about _setjmp vs setjmp.
3201 * alloc.c (test_setjmp, mark_stack):
3202 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
3203 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
3204 (png_load, my_error_exit, jpeg_load):
3205 * process.c (send_process_trap, send_process):
3206 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
3207 The underscored versions are up to 30x faster on some hosts.
3208 Formerly, the code used setjmp+longjmp sometimes and
3209 _setjmp+_longjmp at other times, with no particular reason to
3210 prefer setjmp+longjmp.
3212 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
3214 Fix minor problem found by static checking.
3215 * buffer.c (Fdelete_all_overlays): Return nil.
3217 2012-09-03 Martin Rudalics <rudalics@gmx.at>
3219 * buffer.c (Fdelete_all_overlays): New function.
3221 2012-09-03 Chong Yidong <cyd@gnu.org>
3223 * gtkutil.c: Add extern decl for Qxft.
3225 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
3227 * emacs.c, eval.c: Use bool for boolean.
3228 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
3229 (malloc_using_checking) [DOUG_LEA_MALLOC]:
3230 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
3231 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
3232 (main, decode_env_path, Fdaemon_initialized):
3233 * eval.c (call_debugger, Finteractive_p, interactive_p):

3251 REDISPLAYING_P when unwinding, instead of saving its previous,
3252 always-false value and then restoring it.
3254 Clean up some extern decls.
3255 Mostly, this hoists extern decls out of .c files and into .h files.
3256 That way, we're more likely to catch errors if the interfaces change.

3342 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
3343 more than one grapheme cluster passed to the shaper: compute the
3344 offset adjustment values separately for each cluster. (Bug#11860)
3346 * image.c: Restore mistakenly removed inclusion of w32.h. Without
3347 it, GCC doesn't see prototypes of w32_delayed_load, and complains
3348 about implicit conversions from integer to pointer.
3350 2012-09-01 Daniel Colascione <dancol@dancol.org>
3352 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

3406 window system declarations.
3408 * frame.h: Move common functions here: set_frame_menubar,
3409 x_set_window_size, x_sync, x_get_focus_frame,
3410 x_set_mouse_position, x_set_mouse_pixel_position,
3411 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

3472 * lread.c (init_lread): For out-of-tree builds, only add the
3473 source directory's site-lisp dir to the load-path if it exists,
3474 consistent with in-tree builds. (Bug#12302)
3476 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

3497 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
3498 Add window_closed and button_values. Add void as return value for
3499 add(Button|String|Split). addButton takes int instead of Lisp_Object.

3683 (syms_of_data): Do not define 'interval'.
3684 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
3685 * window.h (decode_valid_window):
3688 * character.c, charset.c, chartab.c: Use bool for booleans.
3689 * character.c (lisp_string_width, string_count_byte8)
3690 (string_escape_byte8):
3691 * charset.c (charset_map_loaded, load_charset_map, read_hex):
3692 (load_charset_map_from_file, map_charset_chars)
3693 (Fdefine_charset_internal, define_charset_internal)
3694 (Fdeclare_equiv_charset, find_charsets_in_text)
3695 (Ffind_charset_region, char_charset, Fiso_charset):
3696 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
3697 (sub_char_table_set, sub_char_table_set_range)
3698 (char_table_set_range, optimize_sub_char_table)
3699 (map_sub_char_table):
3700 Use bool for boolean.
3701 * character.c (str_to_unibyte): Omit last boolean argument; it was
3702 always 0. All callers changed.
3703 * character.h, charset.h: Adjust to match previous changes.
3704 * character.h (char_printable_p): Remove decl of nonexistent function.
3705 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
3706 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
3707 are all boolean, so make them single-bit bitfields.
3709 * lisp.h (ASET): Remove attempt to detect side effects.
3710 It was meant to be temporary and it often doesn't work,
3711 because when IDX has side effects the behavior of IDX==IDX
3712 is undefined. See Stefan Monnier in
3713 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
3715 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
3717 * lisp.h (functionp): New function (extracted from Ffunctionp).
3718 (FUNCTIONP): Use it.
3719 * eval.c (Ffunctionp): Use it.
3721 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3723 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
3724 as that's faster and simpler than static storage. Don't bother
3725 with the g_main_context_query overhead if g_main_context_pending
3726 says no events are pending.
3727 (gfds, gfds_size): Remove these static vars.
3728 (xgselect_initialize): Remove; no longer needed.
3729 All uses and decls removed.
3731 * emacs.c (fatal_error_signal_hook): Remove.
3732 All uses removed. This leftover from old code was always 0.
3734 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
3735 * casefiddle.c (casify_object, casify_region):
3736 * casetab.c (set_case_table):
3737 * category.c, category.h (word_boundary_p):
3738 * category.h (CHAR_HAS_CATEGORY):
3739 Use bool for booleans, instead of int.
3741 2012-08-25 Eli Zaretskii <eliz@gnu.org>
3743 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
3745 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
3747 On assertion failure, print backtrace if available.
3748 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
3749 (die) [ENABLE_CHECKING]: Print a backtrace if available.
3750 * Makefile.in (LIB_EXECINFO): New macro.
3753 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
3754 * bytecode.c (exec_byte_code):
3755 * callint.c (check_mark, Fcall_interactively):
3756 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
3757 (getenv_internal, sync_process_alive, call_process_exited):
3758 * lisp.h (USE_SAFE_ALLOCA):
3759 Use bool for booleans, instead of int.
3760 * lisp.h, process.h: Adjust prototypes to match above changes.
3761 * callint.c (Fcall_interactively): Don't assume the mark's
3762 offset fits in 'int'.
3764 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
3766 * buffer.c, buffer.h: Use bool for boolean.
3767 * buffer.c (reset_buffer_local_variables)
3768 (buffer_lisp_local_variables, Fset_buffer_modified_p)
3769 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
3770 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
3771 (overlay_touches_p, overlay_strings, Foverlay_put)
3772 (report_overlay_modification, call_overlay_mod_hooks):
3773 (mmap_enlarge, mmap_set_vars):
3774 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
3775 Use bool for booleans, instead of int.
3776 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
3777 since the 1-or-0 return value is always ignored anyway.
3778 (mmap_initialized_p):
3779 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
3780 * buffer.h, lisp.h: Adjust prototypes to match above changes.
3782 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3784 * bidi.c: Use bool for boolean.
3785 This is a bit more readable, and makes the text segment of bidi.o
3786 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
3787 Presumably it's faster too.
3788 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
3790 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3791 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
3792 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
3793 (bidi_explicit_dir_char, bidi_level_of_next_char)
3794 (bidi_find_other_level_edge, bidi_move_to_visually_next):
3795 Use bool for booleans, instead of int.
3796 * dispextern.h (bidi_init_it, bidi_paragraph_init)
3797 (bidi_unshelve_cache): Adjust decls to match code.
3799 2012-08-23 Martin Rudalics <rudalics@gmx.at>
3801 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
3804 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
3806 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
3807 * atimer.h: Include <stdbool.h>.
3809 2012-08-22 Dan Nicolaescu <dann@gnu.org>
3811 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
3812 compile time tests instead of run time tests on systems that do
3814 (FRAME_MAC_P): Remove leftover from deleted code.
3815 * frame.c (syms_of_frame): Remove leftover from deleted code.
3817 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
3819 * nsterm.m (insertText:): Don't clear modifiers if code is space.
3821 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
3823 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
3824 Otherwise, the compiler complains about (A?B:C) where B is void
3825 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
3826 (fontset_add): Return void, for FONTSET_ADD.
3828 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3830 * alloc.c: Use bool for booleans.
3831 (gc_in_progress, abort_on_gc)
3832 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3833 (dont_register_blocks) [GC_MALLOC_CHECK]:
3834 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
3835 (check_string_bytes, make_specified_string, memory_full)
3836 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
3837 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
3838 (mark_stack, valid_pointer_p, make_pure_string)
3839 (Fgarbage_collect, survives_gc_p, gc_sweep):
3840 Use bool for booleans, instead of int.
3841 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
3842 Remove unused local.
3843 * alloc.c (PURE_POINTER_P):
3844 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
3845 * editfns.c (Fformat):
3846 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
3848 * fns.c (sweep_weak_table):
3849 * lisp.h (suppress_checking, push_message, survives_gc_p)
3850 (make_pure_string, gc_in_progress, abort_on_gc):
3851 * lread.c (readchar, read1):
3852 * print.c (Fprin1_to_string):
3853 * xdisp.c (push_message):
3854 Use bool for booleans affected directly or indirectly by
3857 Make recently-introduced setters macros.
3858 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
3859 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
3860 (set_fontset_default, set_fontset_fallback): Rename from their
3861 upper-case counterparts, and make them functions rather than macros.
3862 This is more consistent with the other recently-introduced setters.
3863 These don't need to be inline, since they're local.
3865 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
3867 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
3868 the loop (Bug#12247).
3870 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3872 * lisp.h (vcopy): Use memcpy rather than our own loop.
3873 This fixes a performance regression introduced by the recent
3874 addition of vcopy. This means 'vcopy' will need to be modified
3875 for a copying collector, but that's OK. Also, tighten the
3876 checking in the assertion.
3878 2012-08-21 Eli Zaretskii <eliz@gnu.org>
3880 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
3881 components for RTL text (Bug#11860). Adjust X-OFFSET of each
3882 non-base glyph for the width of the base character, according to
3883 what x_draw_composite_glyph_string_foreground expects.
3884 Generate WADJUST value according to composition_gstring_width's
3885 expectations, to produce correct width of the composed character.
3886 Reverse the sign of the DU offset produced by ScriptPlace.
3888 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
3890 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
3892 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3894 Avoid direct writes to contents member of struct Lisp_Vector.
3895 * lisp.h (vcopy): New function to copy data into vector.
3896 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
3897 * fns.c (Ffillarray): Use ASET.
3898 * keyboard.c (timer_check_2): Use AREF and ASET.
3899 (append_tool_bar_item, Frecent_keys): Use vcopy.
3900 * lread.c (read_vector): Use ASET.
3901 * msdos.c (Frecent_doskeys): Use vcopy.
3902 * xface.c (Finternal_copy_lisp_face): Use vcopy.
3903 (Finternal_merge_in_global_face): Use ASET and vcopy.
3904 * xfont.c (xfont_list_pattern): Likewise.
3906 2012-08-21 Martin Rudalics <rudalics@gmx.at>
3908 * window.c (Fwindow_point): For the selected window always return
3909 the position of its buffer's point.
3910 (Fset_window_point): For the selected window always go in its
3911 buffer to the specified position.
3913 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
3915 Setter macros for fontsets.
3916 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
3917 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
3918 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
3921 2012-08-20 Glenn Morris <rgm@gnu.org>
3923 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
3924 Don't assume that `ln -f' works.
3926 2012-08-20 Eli Zaretskii <eliz@gnu.org>
3928 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
3929 and later about non-assignments with no effect. See discussion at
3930 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
3933 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3935 Inline setter functions for Lisp_Objects slots of struct specbinding.
3936 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
3939 2012-08-20 Martin Rudalics <rudalics@gmx.at>
3941 * window.c (select_window): Always make selected window's buffer
3944 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3946 Use AREF and ASET for docstrings of category tables.
3947 * category.h (CATEGORY_DOCSTRING): Use AREF.
3948 (SET_CATEGORY_DOCSTRING): Use ASET.
3949 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
3951 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3953 Inline setter functions for hash table members.
3954 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
3955 (set_hash_hash, set_hash_index): Rename with _slot suffix.
3956 (set_hash_key_and_value, set_hash_index, set_hash_next)
3957 (set_hash_hash): New functions.
3958 * charset.c, fns.c: Adjust users.
3960 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
3962 Inline getter and setter functions for per-buffer values.
3963 * buffer.h (per_buffer_default, set_per_buffer_default)
3964 (per_buffer_value, set_per_buffer_value): New functions.
3965 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
3966 * buffer.c, data.c: Adjust users.
3968 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
3970 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
3972 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
3974 Rely on <config.h> + <unistd.h> to declare 'environ',
3975 as gnulib does this if the system doesn't.
3976 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
3977 Remove declaration. MS-Windows declares it on stdlib.h which is
3978 included by conf_post.h.
3979 * emacs.c (environ) [DOUG_LEA_MALLOC]:
3980 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
3981 * vm-limit.c: Include <unistd.h>, for 'environ'.
3983 * unexaix.c, unexcoff.c: Include "mem-limits.h".
3984 (start_of_data): Remove decl; mem-limits.h provides it.
3986 * xdisp.c (handle_invisible_prop): Make it a bit faster
3987 and avoid a gcc -Wmaybe-uninitialized diagnostic.
3989 2012-08-19 Chong Yidong <cyd@gnu.org>
3991 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
3994 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
3996 * .gdbinit: Use call instead of set when calling a function in the
3999 * data.c (set_internal): Don't use set_blv_found.
4000 (Fkill_local_variable): Likewise.
4002 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
4004 * nsfont.m (ns_ascii_average_width): Ensure the string
4005 ascii_printable is initialized with a null-terminated character
4006 array. Otherwise, it can contain undesired extra characters.
4008 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4010 port new setting code to Sun C 5.8 2005/10/13
4011 * chartab.c, lisp.h (char_table_set, char_table_set_range):
4012 Return void, not Lisp_Object. Otherwise, the compiler
4013 complains about (A?B:C) where B is void and C is Lisp_Object
4014 when compiling CHAR_TABLE_SET, due to the recent change to
4015 the API of sub_char_table_set_contents.
4017 2012-08-18 Chong Yidong <cyd@gnu.org>
4019 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
4020 for the string case (Bug#3874).
4022 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
4024 * buffer.h (BSET): Remove (Bug#12215).

4094 New setter functions.
4096 * termhooks.h (TSET): Remove (Bug#12215).

4098 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
4099 (TERMHOOKS_INLINE): New macro.
4100 (tset_charset_list, tset_selection_alist): New setter functions.
4101 * terminal.c (TERMHOOKS_INLINE):
4102 Define to EXTERN_INLINE, so that the corresponding functions
4103 are compiled into code.
4104 (tset_param_alist): New setter function.
4106 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>

4852 value of EMACSLOADPATH, as it is no longer needed.
4853 (check_windows_init_file): Now external, not static.

4904 * alloc.c (record_xmalloc): New function.
4905 * lisp.h (record_xmalloc): New decl.
4906 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
4907 more like a function. This is because the pointer cast is not
4908 needed. All uses changed.
4909 * print.c (print_string, print_error_message): Avoid length recalc.
4911 Improve fix for macroexp crash with debugging (Bug#12118).
4912 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
4913 ARRAY_MARK_FLAG when checking subscripts, because ASET is

4946 with addition of handling of symlinks and support for 'lstat'.
4947 If possible, get file's attributes and security information by
4948 handle, not by name. Produce S_IFLNK bit for symlinks, when
4949 called from 'lstat'.
4950 (stat, lstat): New functions, call 'stat_worker'.
4951 (symlink, readlink, careadlinkat): Rewritten to create and resolve
4952 symlinks when the underlying filesystem supports them.

4956 Fix macroexp crash on Windows with debugging (Bug#12118).
4957 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
4958 checking subscripts; problem introduced with the recent
4959 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
4960 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
4961 since it's used in non-static inline functions now.
4963 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

5455 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
5456 arms of an 'if', not using conditional expressions; otherwise GDB
5457 complains about the types in the unevaluated arm when the argument
5458 is an integer literal.
5459 (xgetint): Simplify expression.
5460 * alloc.c (gdb_make_enums_visible): New constant. This ports to
5461 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
5462 Zaretskii in <http://bugs.gnu.org/12036#13>.
5463 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
5464 needed now that we have gdb_make_enums_visible.
5465 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
5466 (enum enum_USE_LSB_TAG):
5467 New enum types, packaging up enums that need to be exported to GDB.
5469 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

5485 * xdisp.c (syms_of_xdisp): Likewise.
5486 * xfns.c (syms_of_xfns): Likewise.
5488 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
5490 Fast save_excursion_save and save_excursion_restore.
5491 * lisp.h (struct Lisp_Excursion): New data type.
5492 (PVEC_EXCURSION): New pseudovector type.
5493 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
5494 to deal with it. Adjust comments.
5495 (init_marker, attach_marker): New prototype.
5496 (unchain_marker): Adjust prototype.
5497 * marker.c (attach_marker): Change to global.

5505 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
5507 Fix export of symbols to GDB (Bug#12036).
5508 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
5509 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
5510 emacs.c, as this is a more-suitable home. Had this been done earlier
5511 the fix for 12036 would have avoided some of the problems noted in
5512 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
5513 would have been more obvious.
5514 * emacs.c: Do not include <verify.h>; no longer needed.
5515 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
5516 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
5517 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5518 Remove; now done in lisp.h.
5519 * lisp.h (PUBLISH_TO_GDB): New macro.

5521 (DATA_SEG_BITS): Use it.
5522 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
5523 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
5524 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
5525 not be usable in #if. This simplifies things.
5527 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
5529 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
5531 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

5534 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
5535 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
5536 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
5537 Adjust to changes in lisp.h and emacs.c, by using
5538 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
5539 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
5540 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
5541 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
5542 instead of gdb_valbits.
5543 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
5544 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
5545 instead of gdb_array_mark_flag.
5546 (xboolvector): Get size from $->size, not $->header.size.
5547 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
5548 (xreload, hook-run, hookpost-run): Remove.
5549 * emacs.c: Include <verify.h>.
5550 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
5551 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
5553 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
5554 (gdb_USE_LSB_TAG): New enum constants.
5555 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
5556 Also define these as enum constants, so they're visible to GDB.
5557 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
5558 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
5559 as constants, so they're visible to GDB.
5560 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
5561 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
5562 Now enum constants, not macros, so they're visible to GDB.
5563 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
5564 more convenient now. All uses changed.
5565 (VALMASK) [USE_LSB_TAG]: Also define in this case.
5566 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
5568 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

5575 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
5576 add argument, tune behavior, and adjust all callers.
5578 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
5580 Use typedef for EMACS_INT, EMACS_UINT.
5581 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
5582 than macros. This simplifies debugging in the usual case, since
5583 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
5584 and it allows expressions involving EMACS_INT casts.
5585 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
5587 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

5597 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
5599 Adjust buffer text indirection counters at the end of Fkill_buffer.
5600 * buffer.c (Fkill_buffer): Adjust indirection counters when the
5601 buffer is definitely dead. This should really fix an issue reported
5602 by Christoph Scholtes again. (Bug#12007).
5603 (init_buffer_once): Initialize indirection counters of
5604 buffer_defaults and buffer_local_symbols (for sanity and safety).
5606 2012-07-24 Eli Zaretskii <eliz@gnu.org>
5608 * xdisp.c (init_iterator): Don't compute dimensions of truncation
5609 and continuation glyphs on tooltip frames, leave them at zero.

5637 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
5639 Swap buffer text indirection counters in Fbuffer_swap_text.
5640 * buffer.c (Fbuffer_swap_text): Swap indirections too.
5641 This avoids crash reported by Christoph Scholtes at
5642 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
5644 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
5646 * nsmenu.m (Popdown_data): New struct.

5651 and autorelease them. Also autorelease img and matrix (Bug#12005).
5652 (dealloc): Remove (Bug#12005).

5669 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
5671 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
5672 as it's limited by the amount of memory, not by INT_MAX.
5674 2012-07-21 Eli Zaretskii <eliz@gnu.org>
5676 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
5677 in special-event-map. See the discussion at

5737 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
5738 Adjust users accordingly.
5739 * font.h (font_open_by_name): Adjust prototype.

5758 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
5759 'for_each_per_buffer_object_at'.
5760 All uses changed. It's better to use upper-case for macros that
5761 cannot be implemented as functions, to give the reader a clue
5762 that they're special.
5764 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>

5810 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
5812 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
5814 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
5815 when invoking (make-bool-vector N t) and N is a positive

5823 padding before the data member of a bool vector.
5824 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
5825 than doing the check by hand with an abort ().
5827 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
5829 * eval.c (Fdefvar): Don't check constants since we only set the var if
5830 it's not yet defined anyway (bug#11904).
5832 * lisp.h (last_undo_boundary): Declare new var.
5833 * keyboard.c (command_loop_1): Set it.
5834 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
5835 were auto-added by the command loop (bug#11774).
5837 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
5839 * w32font.c (Qsymbol): Remove local definition.

6338 Move CLASH_DETECTION to configure.
6340 * s/gnu.h: Remove file, which is now empty.
6342 * s/gnu.h, s/gnu-linux.h:
6343 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
6345 2012-07-11 John Wiegley <johnw@newartisans.com>
6347 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
6348 function attribute, so we only use it if it exists in the
6351 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
6353 Avoid call to strlen in fast_c_string_match_ignore_case.
6354 * search.c (fast_c_string_match_ignore_case): Change to use
6355 length argument. Adjust users accordingly.
6356 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
6358 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

6379 (font_open_by_name): Change to use length argument.
6380 Adjust users accordingly.
6381 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
6383 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
6384 Change to return ptrdiff_t.
6385 (xfont_list_pattern, xfont_match): Use length returned by
6386 xfont_decode_coding_xlfd.

6397 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
6399 Remove "#define unix" that is no longer needed (Bug#11905).
6400 * s/aix4-2.h (unix): Remove; no longer needed.
6402 EMACS_TIME simplification (Bug#11875).
6403 This replaces macros (which typically do not work in GDB)
6404 with functions, typedefs and enums, making the code easier to debug.
6405 The functional style also makes code easier to read and maintain.
6406 * systime.h: Include <sys/time.h> on all hosts, not just if
6407 WINDOWSNT, since 'struct timeval' is needed in general.
6408 (EMACS_TIME): Now a typedef, not a macro.
6409 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
6411 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

6413 (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
6414 (EMACS_TIME_LE): Now functions, not macros.
6415 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
6416 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
6417 which are not functions. All uses rewritten to use:
6418 (make_emacs_time): New function.
6419 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
6420 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
6421 not functions. All uses rewritten to use the following, respectively:
6422 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
6423 (add_emacs_time, sub_emacs_time): New functions.
6424 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
6425 * fileio.c (Fcopy_file):
6426 * xterm.c (XTflash): Get the current time closer to when it's used.
6427 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

6433 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
6434 * frame.c (Fmake_terminal_frame):
6435 * gtkutil.c (get_utf8_string):
6437 * nsmenu.m (ns_update_menubar):
6438 * regex.c (regerror):
6439 Prefer memcpy to strncpy and strncat when either will do.
6440 * fileio.c (Fsubstitute_in_file_name):
6441 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
6442 (menu_separator_name_p):
6443 * nsmenu.m (ns_update_menubar):
6444 Prefer memcmp to strncmp when either will do.
6445 * nsterm.m: Include <ftoastr.h>.
6447 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
6448 Prefer snprintf to strncpy.
6449 * nsterm.m (ns_term_init):
6450 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
6451 * nsterm.m (ns_term_init):
6452 Avoid the need for strncpy, by using build_string or
6453 make_unibyte_string directly. Use dtoastr, not snprintf.
6454 * process.c (Fmake_network_process): Diagnose service names that
6455 are too long, rather than silently truncating them or creating
6456 non-null-terminated names.
6457 (Fnetwork_interface_info): Likewise, for interface names.
6458 * sysdep.c (system_process_attributes) [GNU_LINUX]:
6459 Prefer sprintf to strncat.
6460 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
6461 Prefer vsnprintf to vsprintf + strncpy.
6463 2012-07-10 Glenn Morris <rgm@gnu.org>
6465 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
6466 Clarify fallback case.
6468 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6470 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
6471 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
6472 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
6473 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
6474 where argument type is known to be a Lisp_Cons.
6476 2012-07-10 Tom Tromey <tromey@redhat.com>
6478 * bytecode.c (BYTE_CODE_THREADED): New macro.
6479 (BYTE_CODES): New macro. Replaces all old byte-code defines.
6480 (enum byte_code_op): New type.
6481 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.

6484 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6486 Optimize pure C strings initialization.
6487 * lisp.h (make_pure_string): Fix prototype.
6488 (build_pure_c_string): New function, defined as static inline. This
6489 provides a better opportunity to optimize away calls to strlen when
6490 the function is called with compile-time constant argument.
6491 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
6492 argument, adjust users accordingly. Use build_pure_c_string where
6494 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
6495 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
6496 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
6498 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6500 Avoid calls to strlen in miscellaneous functions.
6501 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
6502 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
6503 * lread.c (openp): Likewise.
6505 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
6507 Avoid calls to strlen in path processing functions.
6508 * fileio.c (file_name_as_directory): Add comment. Change to add
6509 srclen argument and return the length of result. Adjust users
6511 (directory_file_name): Fix comment. Change to add srclen argument,
6512 swap 1st and 2nd arguments to obey the common convention.
6513 Adjust users accordingly.
6514 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
6516 2012-07-10 Glenn Morris <rgm@gnu.org>
6518 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
6519 Move PENDING_OUTPUT_COUNT definition to configure.
6521 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
6522 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
6523 * s/gnu.h (DATA_START): Move definitions to configure.
6525 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
6526 We include usg5-4-common.h, which defines them both.
6528 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
6529 O_RDONLY already includes it).
6531 Stop ns builds setting the EMACSLOADPATH environment variable.
6532 * nsterm.m (ns_load_path): Rename from ns_init_paths.
6533 Now it does not set EMACSLOADPATH, just returns the load-path string.
6534 * nsterm.h: Update accordingly.
6535 * lread.c [HAVE_NS]: Include nsterm.h.
6536 (init_lread) [HAVE_NS]: Use ns_load_path.
6537 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
6539 2012-07-09 Glenn Morris <rgm@gnu.org>
6541 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
6542 since the included bsd-common.h does so.
6544 Stop ns builds setting the EMACSPATH environment variable.
6545 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
6546 (ns_init_paths): Do not set EMACSPATH.
6547 * nsterm.h (ns_exec_path): Add it.
6548 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
6551 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
6553 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
6555 * process.c (wait_reading_process_output): 'waitchannels' was unset
6556 when read_kbd || !NILP (wait_for_cell); fix this.
6558 Add GCC-style 'const' attribute to functions that can use it.
6559 * character.h (char_resolve_modifier_mask):
6560 * keyboard.h (make_ctrl_char):
6561 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
6562 (init_character_once, next_almost_prime, init_fns, init_image)
6563 (flush_pending_output, init_sound):
6564 * mem-limits.h (start_of_data):

6568 Declare the dummy function with ATTRIBUTE_CONST.
6569 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
6570 Add decls with ATTRIBUTE_CONST.
6572 Minor improvements to make_formatted_string.
6573 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
6574 where int is good enough, as vsprintf returns an int.
6575 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
6577 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6579 Use make_formatted_string to avoid double length calculation.
6580 * lisp.h (make_formatted_string): New prototype.

6586 * frame.c (make_terminal_frame, set_term_frame_name)
6587 (x_report_frame_params): Likewise.
6588 * image.c (gs_load): Likewise.
6589 * minibuf.c (get_minibuffer): Likewise.

6604 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
6606 Move marker debugging code under MARKER_DEBUG.
6607 * marker.c (MARKER_DEBUG): Move marker debugging code under
6608 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
6609 for bootstrap with --enable-checking (~3x slowdown reported
6610 by Juanma Barranquero <lekktu@gmail.com>).
6611 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
6613 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
6615 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
6616 See <http://bugs.gnu.org/11825#29>.
6618 2012-07-08 Eli Zaretskii <eliz@gnu.org>
6620 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
6621 has no font, use the frame's font. (Bug#11813)
6622 (display_line): Add commentary about displaying truncation glyphs
6624 (produce_special_glyphs): Move here from term.c.
6626 * term.c (produce_special_glyphs): Move to xdisp.c.
6628 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
6631 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
6633 * xdisp.c (display_line): Avoid warning about implicit declaration
6636 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
6638 * lisp.h: Remove empty conditional.
6640 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6642 * lread.c (load_path_check): Now static.
6644 Fix some minor --with-ns problems found by static checking.
6645 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
6646 (x_set_font) [!HAVE_X_WINDOWS]:
6647 * image.c (xpm_load_image) [HAVE_NS]:
6648 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
6649 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
6650 Remove unused local.
6651 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
6652 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
6653 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
6654 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
6655 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
6656 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
6657 Fix pointer signedness problem.
6658 * xfaces.c (FRAME_X_FONT_TABLE):
6659 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
6661 2012-07-07 Glenn Morris <rgm@gnu.org>
6663 * lread.c (load_path_check): New function, split from init_lread.
6664 (init_lread): Reorganize. Motivation:
6665 If EMACSLOADPATH is set, check/warn about that rather than the
6666 defaults, which we are not going to use. Hence we can remove
6667 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
6668 Don't warn if site-lisp directories are missing.
6669 If not installed, start from a blank load-path, since
6670 PATH_LOADSEARCH refers to the eventual installation directories.
6672 2012-07-07 Eli Zaretskii <eliz@gnu.org>
6674 Support truncation and continuation glyphs on GUI frames, when
6675 fringes are disabled. (Bug#11832)
6676 * xdisp.c (init_iterator): Get dimensions of truncation and
6677 continuation glyphs even if on GUI frames.
6678 Adjust it->last_visible_x on GUI frames when the left or right fringes,
6679 or both, are absent.
6680 (start_display, move_it_in_display_line_to): Handle the case of a
6681 GUI frame without a fringe to display continuation or truncation
6683 (insert_left_trunc_glyphs): Support GUI frames: make sure
6684 truncation glyphs overwrite enough glyphs from the current line to
6685 have sufficient space in pixels.
6686 (display_line): Support truncation and continuation glyphs on GUI
6687 frames. If some spare pixels are left on the line after inserting
6688 the truncation glyphs, fill that space with a stretch glyph of a
6689 suitably computed width.
6691 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
6692 produce_glyphs, to support GUI sessions.
6694 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
6696 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
6698 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
6700 Do not require float-time's arg to fit in time_t (Bug#11825).
6701 This works better on hosts where time_t is unsigned, and where
6702 float-time is applied to the (negative) difference between two times.
6703 * editfns.c (decode_time_components): Last arg is now double *,
6704 not int *, and means to store all the result as a double, without
6705 worrying about whether the seconds part fits in time_t.
6706 All callers changed.
6707 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
6708 All callers changed.
6709 (Ffloat_time): Do not fail merely because the specified time falls
6710 outside of time_t range.
6712 2012-07-07 Glenn Morris <rgm@gnu.org>
6714 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
6715 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):

6718 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
6720 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
6721 Update dependencies.
6723 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
6725 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6727 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
6728 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
6729 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
6730 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
6731 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
6732 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
6734 * xfont.c (compare_font_names): Redo to omit the need for casts.
6736 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
6738 * xfns.c (Fx_change_window_property): Doc fix.
6739 * w32fns.c (Fx_change_window_property): Doc fix.
6741 * w32fns.c (Fx_window_property): Accept the same arguments as the
6742 X Windows version. Doc fix.
6743 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
6745 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
6746 Eli Zaretskii <eliz@gnu.org>
6748 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
6749 Windows-specific code from nt/config.nt moved here.
6750 Obsolete settings removed.
6752 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6754 * process.c: Avoid unnecessary calls to gettime.
6755 (wait_reading_process_output): Don't get the time of day
6756 when gobbling data immediately and not waiting, as there's no need
6757 for it in that case. This removes a FIXME.
6759 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
6761 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
6762 is defined (Bug#11768).
6764 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6766 Fix marker debugging code.
6767 * marker.c (byte_char_debug_check): Do not perform the check
6768 if buffer is not multibyte.
6769 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6770 Call byte_char_debug_check with correct arguments.
6772 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6774 Compile marker debugging code only if ENABLE_CHECKING is defined.
6775 * marker.c (byte_char_debug_check, count_markers):
6776 Use only if ENABLE_CHECKING is defined.
6777 (byte_debug_flag): Remove.
6778 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
6779 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

6783 Avoid code repetition in marker-related functions.
6784 * marker.c (attach_marker): New function.
6785 (Fset_marker, set_marker_restricted, set_marker_both)
6786 (set_marker_restricted_both): Use it.
6787 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
6788 Consistently rename charno to charpos.
6789 (marker_position): Add eassert.
6790 (marker_byte_position): Convert to eassert.
6792 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6794 Simplify list operations in unchain_overlay and unchain_marker.
6795 * buffer.c (unchain_overlay): Simplify. Add comment.
6796 * marker.c (unchain_marker): Simplify. Fix comments.
6798 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
6800 Introduce fast path for the widely used marker operation.
6801 * alloc.c (build_marker): New function.
6802 * lisp.h (build_marker): New prototype.
6803 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
6804 * composite.c (autocmp_chars): Likewise.
6805 * editfns.c (buildmark): Remove.
6806 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
6807 (save_restriction_save): Use build_marker.
6808 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
6809 * window.c (save_window_save): Likewise.
6811 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

6814 to avoid redundant calls to unchain_overlay.
6815 * buffer.c (drop_overlay): New function.
6816 (delete_all_overlays, Fdelete_overlay): Use it.
6817 * minibuf.c (get_minibuffer): Fix comment.
6819 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
6821 Port to OpenBSD 5.1 amd64.
6822 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
6823 This is needed for OpenBSD, and should be harmless on all BSD systems.
6824 Also, include <sys/sysctl.h>, as it should be available on all
6825 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
6826 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
6827 use p_pid member, not kp_proc.pid.
6829 2012-07-06 Glenn Morris <rgm@gnu.org>
6831 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
6833 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6835 More xmalloc and related cleanup.
6836 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

6843 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
6844 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
6846 Omit needless casts involving void * pointers and allocation.
6847 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
6848 as the former is more robust if P's type is changed.
6849 Prefer xzalloc to xmalloc + memset 0.
6850 Simplify malloc-or-realloc to realloc.
6851 Don't worry about xmalloc returning a null pointer.
6852 Prefer xstrdup to xmalloc + strcpy.
6853 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
6855 * keyboard.c (apply_modifiers_uncached): Prefer local array to
6856 alloca of a constant.
6858 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6860 * xdisp.c (display_line): Fix horizontal pixel coordinates when
6861 hscroll is larger than the line width. Fixes long and futile
6862 looping inside extend_face_to_end_of_line (on a TTY) producing
6863 glyphs that are not needed and thrown away.
6865 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6867 * marker.c (set_marker_restricted_both): Simplify by using
6870 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6872 * editfns.c (region_limit): Simplify by using clip_to_bounds.
6874 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
6876 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
6877 not defined (Bug#11768).
6878 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
6879 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
6880 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
6881 followed by gtk_box_set_homogeneous (Bug#11768).
6882 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
6883 (update_theme_scrollbar_width, xg_create_scroll_bar):
6884 Use gtk_scrollbar_new (Bug#11768).
6885 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
6886 (is_box_type): New function (Bug#11768).
6887 (xg_tool_item_stale_p): Call is_box_type.
6888 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
6889 with default display (Bug#11768).
6891 2012-07-05 Eli Zaretskii <eliz@gnu.org>
6893 * xdisp.c (window_hscroll_limited): New function.
6894 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
6895 coordinates when window's hscroll is set to insanely large
6898 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
6900 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
6901 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
6903 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
6906 * lisp.h (xzalloc): New prototype. Omit needless casts.
6907 * alloc.c (xzalloc): New function. Omit needless casts.
6908 * charset.c: Omit needless casts. Convert all calls to
6909 xmalloc with following memset to xzalloc.

6959 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
6961 * fileio.c (time_error_value): Check the right error number.
6962 Problem reported by Troels Nielsen in
6963 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
6965 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
6967 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
6968 This should be fixed in a better way; see Eli Zaretskii in
6969 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
6970 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
6972 * fileio.c (time_error_value): Rename from special_mtime.
6973 The old name's problems were noted by Eli Zaretskii in
6974 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
6976 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
6977 This variable's comment says Emacs needs at least one GDB-visible
6978 symbol of type enum pvec_type, to work around GDB problems.
6979 The symbol's value doesn't matter.
6981 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
6982 that causes compilation to fail on pre-C99 compilers.
6984 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
6986 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
6987 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
6989 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
6991 * buffer.c (init_buffer_once): Fix initialization of
6992 headers for buffer_defaults and buffer_local_symbols.
6993 Reported by Juanma Barranquero <lekktu@gmail.com>.
6995 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
6997 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
6998 * lisp.h (enum pvec_type): Use fewer bits.
6999 (PSEUDOVECTOR_SIZE_BITS): New constant.
7000 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
7001 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
7002 change in pvec_type.
7003 (PSEUDOVECTOR_TYPEP): New macro.
7004 (TYPED_PSEUDOVECTORP): Use it.
7005 * fns.c (internal_equal): Adapt code to extract pvectype.
7006 * emacs.c (gdb_pvec_type): Update type.
7007 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
7008 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
7009 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
7010 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
7011 (sweep_vectors): Use it. Use local var `total_bytes' instead of
7012 abusing vector->header.next.nbytes.
7013 (live_vector_p): Use PVEC_TYPE.
7014 (mark_object): Adapt code to extract pvectype. Use switch.
7016 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7018 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
7019 Tighten new eassert a bit.
7021 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7023 Fix compilation with --enable-gcc-warnings and -O1
7025 * doprnt.c (doprnt): Change type of tem to int, initialize
7026 to avoid compiler warning. Add eassert.
7027 * search.c (simple_search): Initialize match_byte to avoid
7028 compiler warning. Add eassert.
7030 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7032 Avoid weird behavior with large horizontal scrolls.
7033 Without this change, for example, large hscroll values would
7034 mess up Emacs's display on Fedora 15 x86, presumably due to
7035 overflows in int calculations in the display code.
7036 Also, if buffers had long lines, Emacs would freeze.
7037 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
7038 (set_window_hscroll): New function, containing the old guts of
7039 Fset_window_hscroll. Return the clipped value.
7040 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
7041 This avoids the need to check against PTRDIFF_MAX.
7043 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
7045 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
7047 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
7049 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
7051 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
7052 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
7053 since GCC 4.4.6 issues a bogus warning for them.
7055 Fix bugs in file timestamp newness comparisons.
7056 * fileio.c (Ffile_newer_than_file_p):
7057 * lread.c (Fload): Use full timestamp resolution of files,
7058 not just the 1-second resolution, so that files that are only
7059 slightly newer still count as newer.
7060 * fileio.c (Ffile_newer_than_file_p): Don't assume file
7061 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
7063 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
7065 * fileio.c: Improve handling of file time marker. (Bug#11852)
7066 (special_mtime): New function.
7067 (Finsert_file_contents, Fverify_visited_file_modtime):
7068 Use it to set special mtime values consistently.
7070 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
7072 * fileio.c (Finsert_file_contents): Properly handle st_mtime
7073 marker for non-existing file. (Bug#11852)
7075 2012-07-03 Glenn Morris <rgm@gnu.org>
7077 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
7078 and did not make it into globals.h).
7080 2012-07-03 Tom Tromey <tromey@redhat.com>
7082 * window.c (Fset_window_margins, Fset_window_fringes)
7083 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
7084 * textprop.c (Fprevious_property_change): No longer static.
7085 * syntax.c (Fsyntax_table_p): No longer static.
7086 * process.c (Fget_process, Fprocess_datagram_address): No longer

7100 * dired.c (Ffile_attributes): No longer static.
7101 * composite.c (Fcomposition_get_gstring): No longer static.
7102 * callproc.c (Fgetenv_internal): No longer static.
7104 * ccl.h: Remove EXFUNs.
7105 * buffer.h: Remove EXFUNs.
7106 * dispextern.h: Remove EXFUNs.
7107 * intervals.h: Remove EXFUNs.
7108 * fontset.h: Remove EXFUN.
7109 * font.h: Remove EXFUNs.
7110 * dosfns.c (system_process_attributes): Remove EXFUN.
7111 * keymap.h: Remove EXFUNs.
7112 * lisp.h: Remove EXFUNs.
7113 * w32term.h: Remove EXFUNs.
7114 * window.h: Remove EXFUNs.
7115 * xsettings.h: Remove EXFUN.
7116 * xterm.h: Remove EXFUN.
7118 2012-07-03 Glenn Morris <rgm@gnu.org>
7120 * lisp.h (Frandom): Make it visible to C.
7121 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
7122 buffer for invisible buffers. (Bug#1229)
7124 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7126 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
7127 values which aren't power of 2.
7128 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
7129 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
7132 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
7134 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
7136 * alloc.c (mark_object): Revert part of last patch to use `switch'.
7138 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7140 * alloc.c (allocate_vector_block): Remove redundant
7141 calls to mallopt if DOUG_LEA_MALLOC is defined.
7142 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
7143 avoid calls to mallopt if zero_vector is returned.
7145 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7147 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
7148 is enabled, avoid dereferencing NULL current_sblock if
7151 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
7153 Cleanup basic buffer management.
7154 * buffer.h (struct buffer): Change layout to use generic vector
7155 marking code. Fix some comments. Change type of 'clip_changed'
7156 to bitfield. Remove unused #ifndef old.
7157 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
7158 (GET_OVERLAYS_AT): Fix indentation.
7159 (for_each_per_buffer_object_at): New macro.
7160 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
7161 (Fbuffer_local_variables): Use it.
7162 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
7163 * alloc.c (allocate_buffer): Adjust to match new layout of
7164 struct buffer. Fix comment.
7165 (mark_overlay): New function.
7166 (mark_buffer): Use it. Use mark_vectorlike to mark normal
7167 Lisp area of struct buffer.
7168 (mark_object): Use it. Adjust marking of misc objects
7169 and related comments.
7171 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
7173 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
7174 wrapper that is not needed because the wrapped code is a no-op (zero
7175 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
7176 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
7178 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
7180 * alloc.c (mark_buffer): Simplify. Remove prototype.
7181 (mark_object): Add comment. Reorganize marking of vector-like
7182 objects. Use CHECK_LIVE for all vector-like objects except buffers
7183 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
7184 Avoid redundant calls to mark_vectorlike for bool vectors.
7186 2012-06-30 Glenn Morris <rgm@gnu.org>
7188 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
7190 * epaths.in (PATH_SITELOADSEARCH): New.
7191 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
7192 This is rather than relying on --enable-locallisppath elements
7193 having "site-lisp" in their names. (Bug#10208#25, 11658)
7195 2012-06-30 Eli Zaretskii <eliz@gnu.org>
7197 * w32proc.c (sys_select): Accept and ignore one more argument.
7199 * w32.c (emacs_gnutls_pull): Call select with one more argument.
7201 * sysselect.h [DOS_NT]: Don't include sys/select.h.
7202 (pselect) [!MS_DOS]: Redirect to sys_select.
7204 * sysdep.c: Don't include dos.h and dosfns.h.
7206 * process.c (sys_select):
7207 * msdos.c (sys_select): Accept one more argument and ignore it.
7209 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
7210 adapt data types and code to that.
7213 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
7214 which clashes with the gnulib function of the same name.
7216 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
7218 * font.c (font_style_to_value, font_style_symbolic)
7219 (font_prop_validate_style): Add type checks for values in
7222 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
7224 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
7227 2012-06-29 Eli Zaretskii <eliz@gnu.org>
7229 * xdisp.c (try_window_id): Undo last change.
7231 * w32.c (getwd): Adjust commentary about startup_dir.
7232 (init_environment): Always call sys_access, even in non-MSVC
7233 builds. Don't chdir to the directory of the Emacs executable.
7234 This undoes code from 1997 which was justified by the need to
7235 "avoid conflicts when removing and renaming directories". But its
7236 downside was that every relative file name was being interpreted
7237 relative to the directory of the Emacs executable, which can never
7238 be TRT. In particular, it broke sys_access when called with
7239 relative file names.
7240 (sys_access): Map GetLastError to errno.
7242 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
7244 * window.h (struct window): Change type of 'fringes_outside_margins'
7245 to bitfield. Fix comment. Adjust users accordingly.
7246 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
7248 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
7251 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

7434 Use sprintf return value instead of invoking strlen on result.
7435 In the old days this wasn't portable, since some sprintf
7436 implementations returned char *. But they died out years ago and
7437 Emacs already assumes sprintf returns int.
7438 Similarly for float_to_string.
7439 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

7447 Use sprintf or float_to_string result to avoid need to call strlen.
7448 * data.c (Fnumber_to_string):
7449 Use make_unibyte_string, since the string must be ASCII.
7450 * lisp.h, print.c (float_to_string): Now returns int length.
7451 * term.c (produce_glyphless_glyph):
7452 Use sprintf result rather than recomputing it.
7454 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
7455 * Makefile.in (ALL_CFLAGS):
7456 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

7483 * xfns.c (x_window): Remove redundant cast.
7485 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
7487 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

7490 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
7492 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
7493 instead of truncating it to 63 (admittedly a generous limit).

7552 * dispnew.c (Fsleep_for, sit_for):
7553 * keyboard.c (kbd_buffer_get_event):
7554 * process.c (Faccept_process_output):
7555 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
7556 This improves on the previous patch, which introduced a bug
7557 when time_t is unsigned and as wide as intmax_t.
7558 See <http://bugs.gnu.org/9000#51>.
7560 2012-06-23 Eli Zaretskii <eliz@gnu.org>
7562 * dispnew.c (sit_for, Fsleep_for):

7623 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
7625 Support higher-resolution time stamps (Bug#9000).
7626 The time stamps are only nanosecond-resolution at the C level,
7627 since that's the best that any real-world system supports now.
7628 But they are picosecond-resolution at the Lisp level, as that's
7629 easy, and leaves room for future OS improvements.
7631 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
7634 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
7635 Don't get current time unless it's needed.
7637 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
7638 now provides it if it's absent.
7639 (start_atimer): Port to higher-res time stamps.
7640 Check for time stamp overflow. Don't get current time more
7641 often than is needed.
7643 * buffer.h (struct buffer): Buffer modtime now has high resolution.
7644 Include systime.h, not time.h.
7645 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
7647 * dired.c: Include stat-time.h.
7648 (Ffile-attributes): File times now have higher resolution.

7651 (struct image): Timestamp now has higher resolution.
7653 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
7654 has at least microseconds now. All uses removed.
7655 (update_frame, update_single_window, update_window, update_frame_1)
7656 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
7657 (duration_to_sec_usec): Remove; no longer needed.
7659 * editfns.c (time_overflow): Now extern.
7660 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
7661 (float-time, Fformat_time_string, Fcurrent_time_string)

7665 (decode_time_components, lisp_seconds_argument): New functions.
7666 (make_time): Now static.
7667 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
7668 Report an error if the time is invalid, rather than having the caller
7671 * fileio.c: Include <stat-time.h>
7672 (Fcopy_file): Copy higher-resolution time stamps.
7673 Prefer to set the time stamp via a file descriptor if that works.
7674 (Fset_file_times, Finsert_file_contents, Fwrite_region)
7675 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
7676 (Fvisited_file_modtime, Fset_visited_file_modtime):
7677 Support higher-resolution time stamps.
7679 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
7681 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
7683 * image.c (prepare_image_for_display, clear_image_cache)
7684 (lookup_image): Port to higer-resolution time stamps.
7686 * keyboard.c (start_polling, bind_polling_period):
7687 Check for time stamp overflow.
7688 (read_char, kbd_buffer_get_event, timer_start_idle)
7689 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
7690 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
7691 Port to higher-resolution time stamps. Do not assume time_t is signed.
7692 (decode_timer): New function. Timers are now vectors of length 9,
7693 not 8, to accommodate the picosecond component.
7694 (timer_check_2): Use it.
7696 * nsterm.m (select_timeout, timeval_subtract): Remove.
7697 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
7698 as they're a bit more accurate and handle overflow better.
7699 (ns_select): Change prototype to be compatible with pselect.
7700 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
7701 * nsterm.h (ns_select): Adjust prototype.
7703 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
7704 us-resolution time stamps.
7705 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
7707 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
7709 * lisp.h (time_overflow): New decl.
7710 (wait_reading_process_output): First arg is now intmax_t, not int,
7711 to accommodate larger waits.
7713 * process.h (struct Lisp_Process.read_output_delay):
7714 Now counts nanoseconds, not microseconds.
7715 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
7717 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
7718 (wait_reading_process_output):
7719 Port to ns-resolution time stamps.
7720 (Faccept_process_output, wait_reading_process_output):
7721 Check for time stamp overflow. Do not assume time_t is signed.
7722 (select_wrapper): Remove; we now use pselect.
7723 (Fprocess_attributes): Now generates ns-resolution time stamps.
7725 * sysdep.c: Include utimens.h. Don't include utime.h
7726 or worry about struct utimbuf; gnulib does that for us now.
7727 (gettimeofday): Remove; gnulib provides a substitute.
7728 (make_timeval): New function.
7729 (set_file_times): Now sets ns-resolution time stamps.
7730 New arg FD; all uses changed.
7731 (time_from_jiffies, ltime_from_jiffies, get_up_time)
7732 (system_process_attributes):
7733 Now returns ns-resolution time stamp. All uses changed.
7734 Check for time stamp overflow.
7736 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
7737 provides a substitute now.
7739 * systime.h: Include timespec.h rather than sys/time.h and time.h,
7740 since it guarantees struct timespec.
7741 (EMACS_TIME): Now struct timespec, so that we can support
7742 ns-resolution time stamps.
7743 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
7744 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
7745 (EMACS_USECS): Remove.
7746 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,

7750 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

7757 (make_timeval, make_lisp_time, decode_time_components): New decls.
7758 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
7759 that it mishandled time_t overflow. You can't compare by subtracting!
7760 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
7761 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

7800 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
7801 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,

7840 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
7841 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with

7852 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
7853 gets killed during executing of this function (Bug#11665).
7854 Try to always return Qt when the buffer has been actually killed.
7855 (Vkill_buffer_query_functions): In doc-string say that functions
7856 run by this hook should not change the current buffer.
7858 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

7883 argument were confusing, as 'eassert' typically does not evaluate
7886 * coding.c (produce_chars): Use ptrdiff_t, not int.
7888 * xterm.c (x_draw_underwave): Check for integer overflow.
7889 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

8211 0 items. Allocate new vector from block if vector size is less than
8212 or equal to VBLOCK_BYTES_MAX.
8213 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
8214 (init_alloc_once): Add call to init_vectors.
8216 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
8218 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
8220 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
8222 * doprnt.c (doprnt): Truncate multibyte char correctly.
8223 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
8224 would mishandle a string argument "Xc" if X was a multibyte
8225 character of length 2: it would truncate after X's first byte
8226 rather than including all of X.
8228 2012-06-06 Chong Yidong <cyd@gnu.org>
8230 * buffer.c (word_wrap): Doc fix.
8232 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>
8234 * xdisp.c (note_mode_line_or_margin_highlight): Pacify gcc -Wall.

8248 2012-06-03 Chong Yidong <cyd@gnu.org>
8250 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
8253 2012-06-03 Chong Yidong <cyd@gnu.org>
8255 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
8256 (note_mode_line_or_margin_highlight): If there is no help echo,
8257 use mode-line-default-help-echo. Handle the case where the mouse
8258 position is past the end of the mode line string.
8260 * buffer.c (buffer_local_value_1): New function, split from
8261 Fbuffer_local_value; can return Qunbound.
8262 (Fbuffer_local_value): Use it.
8263 (Vmode_line_format): Docstring tweaks.
8265 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
8267 * sysdep.c (system_process_attributes): Improve comment.
8269 2012-06-02 Stefan Monnier <monnier@iro.umontreal.ca>
8271 * keyboard.c: Export real-this-command to Elisp.
8272 (syms_of_keyboard): Rename real_this_command to Vreal_this_command
8273 and DEFVAR it. Update all users.
8275 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
8277 * minibuf.c (Fassoc_string): Remove duplicate declaration.
8279 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
8280 Convert pctcpu and pctmem to Lisp float properly.
8281 Let the compiler fold better, as 100.0/0x8000 is exact.
8283 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
8285 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
8288 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
8290 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
8292 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
8294 For a 'struct window', replace some Lisp_Object fields to
8295 bitfields where appropriate, remove unused fields.
8296 * window.h (struct window): Remove unused 'last_mark_x' and
8297 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
8298 change its type from Lisp_Object to bitfield.
8299 Change type of 'force_start', 'optional_new_start',
8300 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
8301 fields from Lisp_Object to bitfield. Adjust users accordingly.
8303 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8305 Pacify gcc -Wdouble-precision when using Xaw.
8306 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
8307 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
8308 Use 'float' consistently, rather than 'float' in most places
8309 and 'double' in a couple of places.
8311 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8313 * xdisp.c (handle_stop): Detect whether we have overlay strings
8314 loaded by testing it->current.overlay_string_index to be
8315 non-negative, instead of checking whether n_overlay_strings is
8316 positive. (Bug#11587)
8318 2012-05-31 Chong Yidong <cyd@gnu.org>
8320 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
8322 * doc.c (Fsubstitute_command_keys): Doc fix.
8324 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8326 * search.c (search_buffer): Remove calls to
8327 r_alloc_inhibit_buffer_relocation, as it is now called by
8328 maybe_unify_char, which was the cause of relocation of buffer text
8331 2012-05-31 Eli Zaretskii <eliz@gnu.org>
8333 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
8334 for the duration of call to load_charset, to avoid problems with
8335 callers of maybe_unify_char that access buffer text through C
8338 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
8339 decrement the inhibition flag, instead of just setting or
8342 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
8344 Remove obsolete '#define static' cruft.
8345 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
8346 This #undef was "temporary" in 2000; it is no longer needed
8347 now that '#define static' has gone away.
8348 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
8349 (gray_bitmap_bits): Remove; no longer needed.
8350 All uses replaced with definiens.
8351 * xterm.c: Include "bitmaps/gray.xbm".
8353 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8355 Clean up __executable_start, monstartup when --enable-profiling.
8356 The following changes affect the code only when profiling.
8357 * dispnew.c (__executable_start): Rename from safe_bcopy.
8358 Define only on platforms that need it.
8359 * emacs.c: Include <sys/gmon.h> when profiling.
8360 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
8361 (__executable_start): Remove decl, since lisp.h does it now.
8362 (safe_bcopy): Remove decl; no longer has that name.
8363 (main): Coalesce #if into single bit of code, for simplicity.
8364 Cast pointers to uintptr_t, since standard libraries want integers
8366 * lisp.h (__executable_start): New decl.
8368 2012-05-31 Glenn Morris <rgm@gnu.org>
8370 * image.c (Fimagemagick_types): Doc fix.
8372 2012-05-30 Jim Meyering <meyering@redhat.com>
8374 * callproc.c (Fcall_process_region): Include directory component
8375 in mkstemp error message (Bug#11586).
8377 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
8379 * alloc.c, lisp.h (make_pure_vector): Now static.
8381 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>

8384 Move to byte-run.el.
8385 (Fautoload): Do the hash-doc more carefully.
8386 * data.c (Fdefalias): Purify definition, except for keymaps.
8387 (Qdefun): Move from eval.c.
8388 * lisp.h (Qdefun): Remove.
8389 * lread.c (read1): Tiny simplification.
8391 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
8393 Do not create empty overlays with the evaporate property (Bug#9642).
8394 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
8395 Bug#9642, but explicitly check that the buffer the overlay would
8396 be moved to is live and rearrange lines to make sure that errors
8397 will not put the overlay in an inconsistent state.
8398 (Fdelete_overlay): Cosmetics.
8400 2012-05-28 Eli Zaretskii <eliz@gnu.org>
8402 * w32term.c (my_bring_window_to_top): New function.
8403 (x_raise_frame): Use handle returned by DeferWindowPos, which
8404 could be different from the original one.
8405 Call my_bring_window_to_top instead of my_set_foreground_window.
8408 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
8409 by calling BringWindowToTop.
8411 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
8412 (WM_EMACS_END): Increase by one.
8414 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
8416 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
8417 This avoids undefined behavior that might cause the eassert
8418 to not catch an out-of-range value.
8420 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
8422 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
8423 Update dependencies.
8425 2012-05-27 Eli Zaretskii <eliz@gnu.org>
8427 * bidi.c (bidi_mirror_char): Fix last change.
8429 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
8431 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
8432 when referring to sectname field in printf format.
8434 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
8436 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
8437 Only r_alloc_inhibit_buffer_relocation needed to be added;
8438 the others were already declared.
8440 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
8441 before checking whether it's out of range. Put the check inside
8443 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
8445 2012-05-27 Ken Brown <kbrown@cornell.edu>
8447 * callproc.c (Fcall_process): Restore a line that was accidentally
8448 commented out in the 2011-02-13 change (bug#11547).
8450 2012-05-27 Eli Zaretskii <eliz@gnu.org>
8452 * lisp.h [REL_ALLOC]: Add prototypes for external functions
8453 defined on ralloc.c.
8455 * buffer.c [REL_ALLOC]: Remove prototypes of
8456 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
8457 they are now on lisp.h.
8459 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
8461 * search.c (search_buffer): Use it to inhibit relocation of buffer
8462 text while re_search_2 is doing its job, because re_search_2 is
8463 passed C pointers to buffer text. (Bug#11519)
8465 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
8468 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
8469 state after an additional call to move_it_in_display_line_to, keep
8470 the values of it->max_ascent and it->max_descent found for the
8472 (pos_visible_p): Revert the comparison against bottom_y to what it
8473 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
8476 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8478 Fix coding-related core dumps with gcc -ftrapv.
8479 The code was computing A - B, where A and B are pointers, and B is
8480 random garbage. This can lead to core dumps on platforms that
8481 have special pointer registers, and it also leads to core dumps on
8482 x86-64 when compiled with gcc -ftrapv. The fix is to compute
8483 A - B only when B is initialized properly.
8484 * coding.c (coding_set_source, coding_set_destination): Return void.
8485 (coding_change_source, coding_change_destinations): New functions,
8486 with the old behaviors of coding_set_source and coding_set_destination.
8487 All callers that need an offset changed to use these new functions.
8489 2012-05-26 Glenn Morris <rgm@gnu.org>
8491 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
8493 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8495 Extend mouse support on W32 text-mode console.
8496 * xdisp.c (draw_row_with_mouse_face):
8497 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
8499 * w32console.c: Include window.h.
8500 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
8502 (initialize_w32_display): Initialize mouse-highlight data.
8504 * w32inevt.c: Include termchar.h and window.h.
8505 (do_mouse_event): Support mouse-autoselect-window. When the mouse
8506 moves, call note_mouse_highlight. If help_echo changed, call
8507 gen_help_event to produce help-echo message in the echo area.
8508 Call clear_mouse_face if mouse_face_hidden is set in the mouse
8511 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
8513 * lread.c (read1): Simplify slightly to avoid an overflow warning
8514 with GCC 4.7.0 on x86-64.
8516 2012-05-26 Eli Zaretskii <eliz@gnu.org>
8518 * bidi.c (bidi_mirror_char): Revert last change: an int is
8519 definitely wide enough here.
8521 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
8523 Fix integer width and related bugs (Bug#9874).
8524 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
8525 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
8526 (string_bytes, check_sblock, allocate_string_data):
8527 (compact_small_strings, Fmake_bool_vector, make_string)
8528 (make_unibyte_string, make_multibyte_string)
8529 (make_string_from_bytes, make_specified_string)
8530 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
8531 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
8533 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8534 (allocate_pseudovector):
8535 Use int, not EMACS_INT, where int is wide enough.
8536 (inhibit_garbage_collection, Fgarbage_collect):
8537 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8538 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
8539 int might not be wide enough.
8540 (bidi_cache_search, bidi_cache_find, bidi_init_it)
8541 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
8542 (bidi_at_paragraph_end, bidi_find_paragraph_start)
8543 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
8544 (bidi_level_of_next_char, bidi_move_to_visually_next):
8545 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8546 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
8547 (Fkill_buffer, Fset_buffer_major_mode)
8548 (advance_to_char_boundary, Fbuffer_swap_text)
8549 (Fset_buffer_multibyte, overlays_at, overlays_in)
8550 (overlay_touches_p, struct sortvec, record_overlay_string)
8551 (overlay_strings, recenter_overlay_lists)
8552 (adjust_overlays_for_insert, adjust_overlays_for_delete)
8553 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
8554 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
8555 (Foverlay_recenter, last_overlay_modification_hooks_used)
8556 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
8557 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8558 (validate_region): Omit unnecessary test for b <= e,
8559 since that's guaranteed by the previous test.
8560 (adjust_overlays_for_delete): Avoid pos + length overflow.
8561 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
8562 (report_overlay_modification):
8563 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8564 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
8565 Omit pointer cast, which isn't needed anyway, and doesn't work
8566 after the EMACS_INT -> ptrdiff_t change.
8567 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
8568 * buffer.h: Adjust decls to match defn changes elsewhere.
8569 (struct buffer_text, struct buffer):
8570 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8571 Use EMACS_INT, not int, where int might not be wide enough.
8572 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
8573 not int, to avoid needless 32-bit limit on 64-bit hosts.
8574 (exec_byte_code): Use tighter memory-full test, one that checks
8575 for alloca overflow. Don't compute the address of the object just
8576 before an array, as that's not portable. Use EMACS_INT, not
8577 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
8578 * callint.c (Fcall_interactively):
8579 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8580 * callproc.c (call_process_kill, Fcall_process):
8581 Don't assume pid_t fits into an Emacs fixnum.
8582 (call_process_cleanup, Fcall_process, child_setup):
8583 Don't assume pid_t fits into int.
8584 (call_process_cleanup, Fcall_process, delete_temp_file)
8585 (Fcall_process_region):
8586 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8587 (Fcall_process): Simplify handling of volatile integers.
8588 Use int, not EMACS_INT, where int will do.
8589 * casefiddle.c (casify_object, casify_region, operate_on_word)
8590 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
8591 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8592 (casify_object): Avoid integer overflow when overallocating buffer.
8593 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
8594 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
8595 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
8596 * category.h (CATEGORYP): Don't assume arg is nonnegative.
8597 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
8598 integers are now checked earlier. All uses replaced with XINT.
8600 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8601 For CCL_MapSingle, check that content and value are in int range.
8602 (ccl_driver, Fregister_code_conversion_map):
8603 Check that Vcode_version_map_vector is a vector.
8604 (resolve_symbol_ccl_program): Check that vector header is in range.
8605 Always copy the vector, so that we can check its contents reliably
8606 now rather than having to recheck each instruction as it's being
8607 executed. Check that vector words fit in 'int'.
8608 (ccl_get_compiled_code, Fregister_ccl_program)
8609 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
8610 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
8611 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
8612 contents are in range.
8613 (Fccl_execute_on_string): Check that status is in range.
8614 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
8615 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
8616 Accept and return EMACS_INT, not int, because callers can pass values
8618 (c_string_width, strwidth, lisp_string_width, chars_in_text)
8619 (multibyte_chars_in_text, parse_str_as_multibyte)
8620 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
8621 (str_as_unibyte, str_to_unibyte, string_count_byte8)
8622 (string_escape_byte8, Fget_byte):
8623 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
8624 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
8625 avoid mishandling large integers.
8626 * character.h: Adjust decls to match defn changes elsewhere.
8627 * charset.c (load_charset_map_from_file, find_charsets_in_text)
8628 (Ffind_charset_region):
8629 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
8630 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
8631 (load_charset_map_from_vector, Fdefine_charset_internal):
8632 Don't assume fixnum fits in int.
8633 (load_charset_map_from_vector, Fmap_charset_chars):
8634 Remove now-unnecessary CHECK_NATNUMs.
8635 (Fdefine_charset_internal): Check ranges here, more carefully.
8636 Don't rely on undefined behavior with signed left shift overflow.
8637 Don't assume unsigned int fits into fixnum, or that fixnum fits
8638 into unsigned int. Don't require max_code to be a valid fixnum;
8639 that's not true for gb10830 4-byte on a 32-bit host. Allow
8640 invalid_code to be a cons, for the same reason. Require code_offset
8641 to be a character. Avoid int overflow if max_char is close
8643 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
8644 this is intended anyway and avoids some undefined behavior.
8645 (load_charset_map): Pass unsigned, not int, as 2nd arg of
8646 INDEX_TO_CODE_POINT, as that's what it expects.
8647 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
8648 * charset.h (DECODE_CHAR): Return int, not unsigned;
8649 this is what was intended anyway, and it avoids undefined behavior.
8650 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
8651 integer-overflow issues.

9360 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
9361 (EMACS_UINT): Define unconditionally now.
9362 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
9363 (BITS_PER_EMACS_INT): New constants, replacing
9364 what used to be in config.h, but not useful in #if.
9365 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
9366 define them any more.
9367 (VAL_MAX): New macro.
9369 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
9370 BITS_PER_EMACS_INT, in #if.
9371 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
9372 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
9373 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
9374 * s/ms-w32.h (DATA_START):
9375 Move here from removed file m/intel386.h.
9376 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
9377 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
9379 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
9381 Assume C89 or later.
9382 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
9383 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
9385 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
9386 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
9387 * textprop.c, tparam.c (NULL): Remove.
9388 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
9389 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
9390 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
9391 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
9392 * xterm.c (input_signal_count): Assume volatile works.
9394 2012-05-21 Ken Brown <kbrown@cornell.edu>
9396 * xgselect.c (xg_select): Fix first argument in call to 'select'
9399 2012-05-20 Ken Brown <kbrown@cornell.edu>
9401 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
9402 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
9404 2012-05-19 Ken Brown <kbrown@cornell.edu>
9406 * xfns.c (x_in_use): Remove `static' qualifier.
9407 * xterm.h (x_in_use): Declare.
9408 * xgselect.c: Include xterm.h.
9409 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
9410 and `display_arg' (bug#9754).
9412 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
9414 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
9416 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
9417 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
9419 2012-05-18 Eli Zaretskii <eliz@gnu.org>
9421 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
9423 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
9424 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
9426 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
9427 reference to image_cache->refcount.
9428 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
9430 2012-05-17 Juri Linkov <juri@jurta.org>
9432 * search.c (Fword_search_regexp, Fword_search_backward)
9433 (Fword_search_forward, Fword_search_backward_lax)
9434 (Fword_search_forward_lax): Move functions to isearch.el
9435 (bug#10145, bug#11381).
9437 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
9439 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
9441 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
9443 * lread.c (init_obarray): Declare Qt and Qnil as special.
9445 2012-05-14 Glenn Morris <rgm@gnu.org>
9447 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
9448 Put "libexec" before "bin", for the sake of init_callproc_1.
9450 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9452 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
9454 * unexaix.c: Port to more-recent AIX compilers.
9455 (report_error, report_error_1, make_hdr, copy_sym)
9456 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
9457 Make arguments const char *, not char *, to avoid violations of C
9458 standard and to fix some AIX warnings reported by Gilles Pion.
9460 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9462 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
9463 already have overlays loaded.
9464 (handle_single_display_spec): Before returning without displaying
9465 fringe bitmap, synchronize the bidi iterator with the main display
9466 iterator, by calling iterate_out_of_display_property.
9467 (iterate_out_of_display_property): Detect buffer iteration by
9468 testing that it->string is a Lisp string.
9469 (get_next_display_element): When the current object is exhausted,
9470 and there's something on it->stack, call set_iterator_to_next to
9471 proceed with what's on the stack, instead of returning zero.
9472 (set_iterator_to_next): If called at the end of a Lisp string,
9473 proceed to consider_string_end without incrementing string
9474 position. Don't increment display vector index past the end of
9475 the display vector. (Bug#11417)
9476 (pos_visible_p): Don't report a position visible when move_it_to
9477 stopped at the last line of window, which happens to be scanned
9478 backwards by the bidi iteration. (Bug#11464)
9480 2012-05-14 Eli Zaretskii <eliz@gnu.org>
9482 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
9483 and right-margin display specs even if the spec is invalid or we
9484 are on a TTY, and thus unable to display on the fringes.
9485 That's because the text with the property will not be displayed anyway,
9486 so we need to signal to the caller that this is a "replacing"
9487 display spec. This fixes display when the spec is invalid or we
9490 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
9492 * unexaix.c (make_hdr): Fix typo in prototype.
9493 This bug broke the build on AIX. Problem reported by Gilles Pion.
9495 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
9497 * keyboard.c (kbd_buffer_get_event): Read special events also in
9498 batch mode. (Bug#11415)
9500 2012-05-12 Glenn Morris <rgm@gnu.org>
9502 * ns.mk: Update for ns_appbindir no longer having trailing "/".
9504 2012-05-12 Eli Zaretskii <eliz@gnu.org>
9506 * lisp.mk (lisp): Add newcomment.elc.
9508 2012-05-12 Glenn Morris <rgm@gnu.org>
9510 * Makefile.in (MKDIR_P): New, set by configure.
9511 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
9513 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
9515 Remove unused function hourglass_started.
9516 * dispextern.h (hourglass_started):
9517 * w32fns.c (hourglass_started):
9518 * xdisp.c (hourglass_started): Remove.
9520 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
9522 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
9523 Update dependencies.
9525 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
9527 * xgselect.c (xg_select): Put maxfds+1 into a var.
9528 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
9530 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
9532 2012-05-10 Dave Abrahams <dave@boostpro.com>
9534 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
9535 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
9537 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
9539 * dbusbind.c (xd_registered_buses): New internal Lisp object.
9540 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
9541 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
9542 Initialize xd_registered_buses.
9544 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
9546 Untag more efficiently if USE_LSB_TAG.
9547 This is based on a proposal by YAMAMOTO Mitsuharu in
9548 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
9549 For an admittedly artificial (nth 8000 longlist) benchmark on
9550 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
9551 Emacs's overall text size by 1%.
9552 * lisp.h (XUNTAG): New macro.
9553 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
9554 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
9555 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
9556 * eval.c (Fautoload):
9557 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
9558 * frame.h (XFRAME): Use XUNTAG.
9560 Port recent dbusbind.c changes to 32-bit --with-wide-int.
9561 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
9562 Remove unportable assumptions about print widths of types like
9564 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
9565 intptr_t when converting between pointer and integer, to avoid GCC
9566 warnings about wrong width.
9568 2012-05-09 Eli Zaretskii <eliz@gnu.org>
9570 * w32proc.c (new_child): Force Windows to reserve only 64KB of
9571 stack for each reader_thread, instead of defaulting to 8MB
9572 determined by the linker. This avoids failures in creating
9573 subprocesses on Windows 7, see the discussion in this thread:
9574 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
9576 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
9578 Fix up display of the *Minibuf-0* buffer in the mini window.
9579 * keyboard.c (read_char): Don't clear the echo area if there's no
9581 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
9582 contents of *Minibuf-0*) if there's no message displayed in its stead.
9584 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
9586 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
9589 2012-05-06 Chong Yidong <cyd@gnu.org>
9591 * lisp.mk (lisp): Update.
9593 2012-05-05 Jim Meyering <meyering@redhat.com>
9595 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
9597 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
9599 * data.c (PUT_ERROR): New macro.
9600 (syms_of_data): Use it. Add new error type `user-error'.
9601 * undo.c (user_error): New function.
9602 (Fprimitive_undo): Use it.
9603 * print.c (print_error_message): Adjust print style for `user-error'.
9604 * keyboard.c (user_error): New function.
9605 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
9607 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
9609 Do not limit current-time-string to years 1000..9999.
9610 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
9611 (Fcurrent_time_string): Support any year that is supported by the
9612 underlying localtime representation. Don't use asctime, as it
9613 has undefined behavior for years outside the range -999..9999.
9615 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
9617 Fix race conditions involving setenv, gmtime, localtime, asctime.
9618 Without this fix, interrupts could mess up code that uses these
9619 nonreentrant functions, since setting TZ invalidates existing
9620 tm_zone or tzname values, and since most of these functions return
9621 pointers to static storage.
9622 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
9623 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
9624 Grow the critical sections to include not just invoking
9625 localtime/gmtime, but also accessing these functions' results
9626 including their tm_zone values if any, and any related TZ setting.
9627 (format_time_string): Last arg is now struct tm *, not struct tm **,
9628 so that the struct tm is saved in the critical section.
9629 All callers changed. Simplify allocation of initial buffer, partly
9630 motivated by the fact that memory allocation needs to be outside
9631 the critical section.
9633 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
9635 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
9636 with RESET_INTERVAL.
9638 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
9639 Remove duplicated buffer name initialization.
9641 2012-05-02 Jim Meyering <jim@meyering.net>
9643 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
9645 * xfns.c (x_window): Use xstrdup (Bug#11375).
9647 2012-05-02 Eli Zaretskii <eliz@gnu.org>
9649 * xdisp.c (pos_visible_p): If already at a newline from the
9650 display string before the 'while' loop, don't walk back the glyphs
9651 from it3.glyph_row. Solves assertion violation when the display
9652 string begins with a newline (egg.el). (Bug#11367)
9654 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
9656 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
9659 2012-05-01 Glenn Morris <rgm@gnu.org>
9661 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
9662 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
9663 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
9664 All were removed before 23.1.
9666 * dispnew.c: Remove HAVE_LIBNCURSES test;
9667 it is always true on relevant platforms.
9669 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
9670 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
9672 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
9674 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
9676 * .gdbinit (xpr): Remove checks for no longer existing misc types.
9677 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
9680 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
9682 Do not avoid creating empty evaporating overlays (Bug#9642).
9683 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
9684 That is, do not delete an evaporating overlay if it becomes
9685 empty after its bounds are adjusted to fit within its buffer.
9686 This fix caused other problems, and I'm reverting it until we get
9687 to the bottom of them.
9689 2012-04-27 Chong Yidong <cyd@gnu.org>
9691 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
9693 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9695 * xdisp.c (pos_visible_p): If the window start position is beyond
9696 ZV, start the display from buffer beginning. Prevents assertion
9697 violation in init_iterator when the minibuffer window is scrolled
9700 * window.c (window_scroll_pixel_based): Likewise.
9702 2012-04-27 Chong Yidong <cyd@gnu.org>
9704 * keymap.c (where_is_internal): Doc fix (Bug#10872).
9706 2012-04-27 Glenn Morris <rgm@gnu.org>
9708 * fileio.c (Fcopy_file, Fset_file_selinux_context):
9709 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
9711 2012-04-27 Eli Zaretskii <eliz@gnu.org>
9713 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
9714 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
9716 2012-04-26 Eli Zaretskii <eliz@gnu.org>
9718 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
9719 display element, check also the underlying string or buffer
9720 character. (Bug#11341)
9722 * w32menu.c: Include w32heap.h.
9723 (add_menu_item): If the call to AppendMenuW (via
9724 unicode_append_menu) fails, disable Unicode menus only if we are
9725 running on Windows 9X/Me.
9727 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
9729 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
9730 (xgetint): Add missing shift for LSB tags.
9732 2012-04-24 Martin Rudalics <rudalics@gmx.at>
9734 * keyboard.c (read_char): Don't wipe echo area for select window
9735 events: These might get delayed via `mouse-autoselect-window'
9738 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
9740 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
9741 manipulation of :loaded-from data.
9743 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
9745 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
9746 now a cons (bug#11311).
9748 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
9750 Do not create empty overlays with the evaporate property (Bug#9642).
9751 * buffer.c (Fmove_overlay): Delete an evaporating overlay
9752 if it becomes empty after its bounds are adjusted to fit within
9753 its buffer. Without this fix, in a nonempty buffer (let ((o
9754 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
9755 yields an empty overlay that has the evaporate property, which is
9756 not supposed to happen.
9758 Fix minor GTK3 problems found by static checking.
9759 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
9760 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9761 (struct _EmacsFixedClass, emacs_fixed_get_type):
9762 Move decls here from emacsgtkfixed.h, since they needn't be public.
9763 (emacs_fixed_get_type): Now static.
9764 (emacs_fixed_class_init): Omit unused local.
9765 (emacs_fixed_child_type): Remove; unused.

9767 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
9768 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
9769 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
9770 (EMACS_FIXED_GET_CLASS): Remove; unused.
9771 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
9773 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
9774 Problem reported by Juanma Barranquero for Windows -Wunused-function.
9776 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
9778 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
9779 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
9780 (__malloc_size_t, __malloc_ptrdiff_t):
9781 Remove. All uses removed, replaced by the definiens if needed,
9782 since we can assume C89 or better now.
9783 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
9784 (protect_malloc_state, align, get_contiguous_space)
9785 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
9786 (malloc_atfork_handler_child, malloc_enable_thread)

9791 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
9792 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
9793 Define using prototypes, not old style.
9794 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
9795 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
9796 (align): Don't assume that signed integer overflow wraps around.
9797 Omit unused local var.
9798 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
9799 (_free_internal_nolock, memalign, mallochook, reallochook):
9800 Omit no-longer-needed casts.
9801 (valloc): Use getpagesize, not __getpagesize.
9802 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
9803 (struct hdr): The 'magic' member is now size_t, not unsigned long.
9805 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
9807 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
9809 Move functions from C to Lisp. Make non-blocking method calls
9810 the default. Implement further D-Bus standard interfaces.
9812 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

9860 since the two debugging options are incompatible.
9861 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
9863 (mem_init, mem_insert, mem_insert_fixup):
9864 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
9865 (NEED_MEM_INSERT): Remove; no longer needed.
9867 2012-04-22 Leo Liu <sdl.web@gmail.com>

9894 * print.c (print_preprocess): Only check print_depth if print-circle
9896 (print_object): Check for cycles even when print-circle is nil and
9897 print-gensym is t, but only check print_depth if print-circle is nil.
9899 2012-04-20 Chong Yidong <cyd@gnu.org>
9901 * process.c (wait_reading_process_output): If EIO occurs on a pty,
9902 set the status to "failed" and ensure that sentinel is run.

9917 farther than the first row after the header line, if any.
9918 Don't consider the header-line row as "partially visible", even if

9957 New extern decls, to avoid calling undeclared functions.
9958 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
9959 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
9960 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
9961 (NEED_MEM_INSERT): New macro.
9962 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
9963 Remove one incorrect comment and fix another.

9999 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
10000 * s/netbsd.h, s/sol2-6.h:
10001 Remove definition of GC_MARK_STACK, since the default now works.
10002 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

10030 2012-04-11 Daniel Colascione <dancol@dancol.org>
10032 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
10033 against is gone. It's better to use vfork now so that when Cygwin
10034 gains a new, working vfork, we use it automatically (bug#10398).
10036 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

10089 * minibuf.c (Fread_variable): Callers changed.
10091 2012-04-09 Eli Zaretskii <eliz@gnu.org>
10093 * xdisp.c (set_cursor_from_row): If the display string appears in
10094 the buffer at position that is closer to point than the position
10095 after the display string, display the cursor on the first glyph of
10096 the display string. Fixes cursor display when a 'display' text
10097 property immediately follows invisible text. (Bug#11094)
10099 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
10101 composite.c: use 'double' consistently
10102 * composite.c (get_composition_id): Use 'double' consistently
10103 instead of converting 'float' to 'double' and vice versa; this is
10104 easier to understand and avoids a GCC warning.
10106 2012-04-09 Glenn Morris <rgm@gnu.org>
10108 * Makefile.in: Generate leim-list with bootstrap-emacs, in

10153 [!WINDOWSNT]: New macros.
10154 (init_libxml2_functions, libxml2_loaded_p): New functions.

10158 Calls xmlCleanupParser only if libxml2 was loaded (or statically
10160 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

10162 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
10164 * emacs.c: Don't include libxml/parser.h.

10173 point, use it.vpos to compute how many lines to backtrack after
10174 move_it_to point. (Bug#11133)
10176 2012-04-06 Eli Zaretskii <eliz@gnu.org>
10178 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
10179 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
10180 about subtle differences between FETCH_CHAR* and STRING_CHAR*
10181 macros related to unification of CJK characters. For the details,
10182 see the discussion following the message here:
10183 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.

10199 2012-03-31 Eli Zaretskii <eliz@gnu.org>
10201 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
10202 position we get to after a call to move_it_to fails the
10203 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
10204 only if we wind up in a string from display property. (Bug#11063)
10206 * window.c (Fdelete_other_windows_internal): Invalidate the row
10207 and column information about mouse highlight, so that redisplay
10208 restores it after reallocating the glyph matrices. (Bug#7464)
10210 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
10211 string comes from a `display' text property, use the buffer
10212 position of that property as if we actually saw that position in
10214 (move_it_by_lines): Remove the assertion that
10215 "it->current_x == 0 && it->hpos == 0" which can be legitimately
10216 violated when there's a before-string at the beginning of a line.

10224 extending the face to the end of the line.
10225 (display_line): Call extend_face_to_end_of_line when the default
10226 face was remapped. (Bug#11068)

10259 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
10261 2012-03-24 Eli Zaretskii <eliz@gnu.org>
10263 * s/ms-w32.h (tzname): Include time.h before redirecting to

10268 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
10271 * xterm.c (XTread_socket): Only modify handling_signal if
10272 !SYNC_INPUT. (Bug#11080)
10274 2012-03-23 Eli Zaretskii <eliz@gnu.org>
10276 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
10277 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
10278 when fetching a multibyte character consumes more bytes than
10279 CHAR_BYTES returns, due to unification of CJK characters in
10280 string_char. (Bug#11073)
10282 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
10284 * process.c (wait_reading_process_output): Handle pty disconnect
10285 by refraining from sending oneself a SIGCHLD (bug#10933).

10291 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
10292 Mark string as coming from a prefix property.
10293 (handle_face_prop): Use default face for prefix strings (Bug#4281).
10294 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
10296 2012-03-21 Chong Yidong <cyd@gnu.org>
10298 * xfaces.c (Vface_remapping_alist): Doc fix.
10300 2012-03-20 Eli Zaretskii <eliz@gnu.org>
10302 * w32proc.c (Fw32_set_console_codepage)
10303 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
10306 2012-03-20 Chong Yidong <cyd@gnu.org>
10308 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
10309 to reflect default non-nil value of redisplay-dont-pause.
10311 2012-03-19 Kenichi Handa <handa@m17n.org>
10313 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
10314 it fit in a valid range (Bug#11003).
10316 2012-03-18 Eli Zaretskii <eliz@gnu.org>
10318 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
10319 that is not from display property, accept the row as a "cursor
10320 row" if one of the string's character has a non-nil `cursor'
10321 property. Fixes cursor positioning when there are newlines in
10322 overlay strings, e.g. in icomplete.el. (Bug#11035)
10324 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
10326 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
10328 2012-03-12 Chong Yidong <cyd@gnu.org>
10330 * eval.c (inhibit_lisp_code): Rename from
10331 inhibit_window_configuration_change_hook; move from window.c.
10333 * xfns.c (unwind_create_frame_1, Fx_create_frame):
10334 * window.c (run_window_configuration_change_hook)
10335 (syms_of_window): Callers changed.

10341 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
10343 2012-03-10 Chong Yidong <cyd@gnu.org>
10345 * frame.c (other_visible_frames): Don't assume the selected frame
10346 is visible (Bug#10955).
10348 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
10350 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).

10354 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
10355 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
10358 2012-03-03 Glenn Morris <rgm@gnu.org>
10360 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
10362 2012-03-02 Eli Zaretskii <eliz@gnu.org>
10364 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
10365 position past the first glyph_row that ends at ZV. (Bug#10902)
10366 (redisplay_window, next_element_from_string): Fix typos in
10368 (redisplay_window): Pass to move_it_vertically the margin in
10369 pixels, not in screen lines.
10371 2012-03-02 Glenn Morris <rgm@gnu.org>
10373 * buffer.c (buffer-list-update-hook): Doc fix.
10375 2012-02-29 Eli Zaretskii <eliz@gnu.org>
10377 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
10378 push_it before setting up the iterator for the first overlay
10379 string, even if we have an empty string loaded.
10380 (next_overlay_string): If there's an empty string on the iterator
10381 stack, pop the stack. (Bug#10903)
10383 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
10385 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
10386 Suggested by Stefan Monnier in
10387 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
10388 * alloc.c (widen_to_Lisp_Object): New static function.
10389 (mark_memory): Also mark Lisp_Objects by fetching pointer words
10390 and widening them to Lisp_Objects. This would work even if
10391 USE_LSB_TAG is defined and wide integers are used, which might
10392 happen in a future version of Emacs.
10394 2012-02-25 Chong Yidong <cyd@gnu.org>
10396 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
10399 * xselect.c (Fx_selection_exists_p): Doc fix.
10400 (x_clipboard_manager_save_all): Print an informative message
10401 before saving to clipboard manager.
10403 2012-02-24 Chong Yidong <cyd@gnu.org>
10405 * keyboard.c (process_special_events): Handle all X selection
10406 requests in kbd_buffer, not just the next one (Bug#8869).
10408 2012-02-23 Chong Yidong <cyd@gnu.org>
10410 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
10411 call when setting menu-bar-lines and tool-bar-lines parameters.
10412 (unwind_create_frame_1): New helper function.
10414 * window.c (inhibit_window_configuration_change_hook): New var.
10415 (run_window_configuration_change_hook): Obey it.
10416 (syms_of_window): Initialize it.
10418 2012-02-22 Chong Yidong <cyd@gnu.org>
10420 * xterm.c (x_draw_image_relief): Add missing type check for
10421 Vtool_bar_button_margin (Bug#10743).
10423 2012-02-21 Chong Yidong <cyd@gnu.org>
10425 * fileio.c (Vfile_name_handler_alist): Doc fix.
10427 * buffer.c (Fget_file_buffer): Protect against invalid file
10428 handler return value.
10430 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
10432 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
10433 when computing $valmask.
10435 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
10436 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
10437 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
10438 It's useless in that case, and it can cause problems on hosts
10439 that allocate halves of EMACS_INT values separately.
10440 Reported by Dan Horák. Diagnosed by Andreas Schwab in
10441 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
10442 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
10443 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
10444 it avoids undefined behavior on hosts where shifting right by more
10445 than the word width has undefined behavior.
10447 2012-02-19 Chong Yidong <cyd@gnu.org>
10449 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
10450 (Funhandled_file_name_directory, Ffile_name_as_directory)
10451 (Fdirectory_file_name, Fexpand_file_name)
10452 (Fsubstitute_in_file_name): Protect against invalid file handler
10453 return values (Bug#10845).
10455 2012-02-18 Eli Zaretskii <eliz@gnu.org>
10457 * .gdbinit (pitx): Fix incorrect references to fields of the

10467 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
10469 2012-02-15 Chong Yidong <cyd@gnu.org>
10471 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
10472 marked as special. Also, starting docstrings with * is obsolete.

10485 * keymap.c (Fsingle_key_description): Handle char ranges.
10487 2012-02-12 Chong Yidong <cyd@gnu.org>
10489 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
10490 as that creates a dangerous corner case.
10492 * window.c (Fdelete_window_internal): Invalidate the mouse
10493 highlight (Bug#9904).
10495 2012-02-12 Glenn Morris <rgm@gnu.org>

10498 (Fx_get_selection_internal, Fx_disown_selection_internal)
10499 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
10500 * nsselect.m (Fx_own_selection_internal)
10501 (Fx_disown_selection_internal, Fx_selection_exists_p)
10502 (Fx_selection_owner_p, Fx_get_selection_internal):
10503 Sync docs and argument specs with the xselect.c versions.
10505 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
10507 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
10509 2012-02-11 Eli Zaretskii <eliz@gnu.org>
10511 * w32select.c (Fx_selection_exists_p): Sync doc string and
10512 argument list with xselect.c. (Bug#10783)

10525 2012-02-07 Chong Yidong <cyd@gnu.org>
10527 * buffer.c (Fbuffer_local_variables)
10528 (buffer_lisp_local_variables): Handle unbound vars correctly;
10529 don't let Qunbound leak into Lisp.
10531 2012-02-07 Glenn Morris <rgm@gnu.org>
10533 * image.c (Fimagemagick_types): Doc fix.
10535 * image.c (imagemagick-render-type): Change it from a lisp object
10536 to an integer. Move the doc here from the lisp manual.
10537 Treat all values not equal to 0 the same.

10549 2012-02-04 Chong Yidong <cyd@gnu.org>
10551 * nsterm.m: Declare a global (Bug#10694).
10553 2012-02-04 Eli Zaretskii <eliz@gnu.org>
10555 * w32.c (get_emacs_configuration_options):
10556 Include --enable-checking, if specified, in the return value.
10558 2012-02-04 Martin Rudalics <rudalics@gmx.at>
10560 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
10561 after rounding frame sizes. (Bug#9723)

10566 before BEGV. (Bug#10696)
10568 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
10570 Handle overflow when computing char display width (Bug#9496).
10571 * character.c (char_width): Return EMACS_INT, not int.
10572 (char_width, c_string_width): Check for overflow when
10573 computing the width; this is possible now that individual
10574 characters can have unbounded width. Problem introduced
10575 by merge from Emacs 23 on 2012-01-19.
10577 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
10579 * dbusbind.c (Fdbus_register_method): Mention the return value
10580 :ignore in the docstring.
10582 2012-02-02 Glenn Morris <rgm@gnu.org>
10584 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.

10592 2012-02-02 Kenichi Handa <handa@m17n.org>
10594 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
10595 0, do not call append_composite_glyph.
10597 2012-02-02 Kenichi Handa <handa@m17n.org>
10599 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
10601 (x_produce_glyphs): If the component of a composition is a null
10602 string, set it->pixel_width to 1 to avoid zero-width glyph.
10604 2012-02-01 Eli Zaretskii <eliz@gnu.org>
10606 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
10607 first 2 arguments are identical. This makes inserting large
10608 output from a subprocess an order of magnitude faster on
10609 MS-Windows, where all sbrk'ed memory is always contiguous.
10611 2012-01-31 Glenn Morris <rgm@gnu.org>
10613 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

10649 2012-01-21 Chong Yidong <cyd@gnu.org>
10651 * floatfns.c (Fcopysign): Make the second argument non-optional,
10652 since nil is not allowed anyway.
10654 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>

10667 * character.c (char_width): New function.
10668 (Fchar_width, c_string_width, lisp_string_width):
10669 Use char_width (Bug#9496).

10691 he end column for display of highlight that ends on a newline
10694 2012-01-11 Glenn Morris <rgm@gnu.org>
10696 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
10697 from load-path also when installation-directory is nil. (Bug#10208)
10699 2012-01-10 Glenn Morris <rgm@gnu.org>
10701 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
10703 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
10704 Update template values to be closer to their typical values these days.
10706 2012-01-09 Eli Zaretskii <eliz@gnu.org>
10708 * xdisp.c (rows_from_pos_range): Accept additional argument
10709 DISP_STRING, and accept any glyph in a row whose object is that
10710 string as eligible for mouse highlight. Fixes mouse highlight of
10711 display strings from overlays. (Bug#10464)
10713 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
10715 emacs: fix an auto-save permissions race condition (Bug#10400)
10716 * fileio.c (auto_saving_dir_umask): New static var.
10717 (Fmake_directory_internal): Use it.
10718 (do_auto_save_make_dir): Set it, instead of invoking chmod after
10719 creating the directory. The old code temporarily assigns
10720 too-generous permissions to the directory.
10721 (do_auto_save_eh): Clear it.
10722 (Fdo_auto_save): Catch all errors, not just file errors, so
10723 that the var is always cleared.
10725 2012-01-07 Eli Zaretskii <eliz@gnu.org>
10727 * search.c (scan_buffer): Pass character positions to
10728 know_region_cache, not byte positions. (Bug#6540)

11228 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
11229 is set, removing the need for VIRT_ADDRESS_VARIES.
11230 (PURE_P): Use a more-efficient implementation that needs just one
11231 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
11232 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
11233 to 4 (xorl, subq, cmpq, setbe).
11234 * alloc.c (pure): Always extern now, since that's the
11235 VIRT_ADDR_VARIES behavior.
11236 (PURE_POINTER_P): Use a single comparison, not two, for
11237 consistency with the new puresize.h.
11238 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
11239 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
11240 Remove VIRT_ADDR_VARIES no longer needed.
11242 2011-11-19 Eli Zaretskii <eliz@gnu.org>
11244 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
11245 (erase_phys_cursor, update_window_cursor, show_mouse_face)
11246 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
11247 behave as if the cursor position were at the window margin.
11249 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
11250 and the cursor position is out of bounds, behave as if the cursor
11251 position were at the window margin. (Bug#10075)
11253 2011-11-18 Chong Yidong <cyd@gnu.org>
11255 * window.c (Fwindow_combination_limit): Make first argument

11276 * xdisp.c (row_hash): New function, body extracted from
11277 compute_line_metrics.
11278 (compute_line_metrics): Call row_hash, instead of computing the
11281 * dispnew.c (verify_row_hash): Call row_hash for computing the
11282 hash code of a row, instead of duplicating code from xdisp.c.
11284 * dispextern.h (row_hash): Add prototype.
11286 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

11315 (Fset_window_configuration, save_window_save): Rename all
11316 occurrences of window_nest to window_combination_limit.
11318 2011-11-15 Juanma Barranquero <lekktu@gmail.com>

11322 2011-11-14 Eli Zaretskii <eliz@gnu.org>
11324 * xdisp.c (display_line): Move the call to
11325 highlight_trailing_whitespace before the call to
11326 compute_line_metrics, since the latter needs to see the final

11328 Fixes assertion violations in row_equal_p. (Bug#10035)
11330 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
11332 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
11333 just return (bug#10044).
11335 2011-11-12 Eli Zaretskii <eliz@gnu.org>
11337 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
11338 with user-defined heap size. Bump the default size of the temacs

11340 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
11342 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
11343 current_matrix and desired_matrix. (Bug#9990)
11344 (verify_row_hash) [XASSERTS]: New function.
11345 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
11346 that the hash value of glyph rows is correct.

11375 2011-11-11 Johan Bockgård <bojohan@gnu.org>
11377 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
11378 avoid a crash (bug#9496).
11380 2011-11-09 Chong Yidong <cyd@gnu.org>

11389 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
11391 Avoid some portability problems by eschewing 'extern inline' functions.
11392 The trivial performance wins aren't worth the portability hassles; see
11393 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
11395 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11396 (window_box_width, window_box_left, window_box_left_offset)
11397 (window_box_right, window_box_right_offset): Undo previous change,
11398 by removing the "extern"s.
11399 * intervals.c (adjust_intervals_for_insertion)
11400 (adjust_intervals_for_deletion): Undo previous change,
11401 making these static again.
11402 (offset_intervals, temp_set_point_both, temp_set_point)
11403 (copy_intervals_to_string): No longer inline.
11404 * xdisp.c (window_text_bottom_y, window_box_width)

11428 2011-11-07 Martin Rudalics <rudalics@gmx.at>
11430 * window.h: Declare delete_all_child_windows instead of
11431 delete_all_subwindows.
11432 * window.c (Fwindow_nest, Fset_window_nest)
11433 (Fset_window_new_total, Fset_window_new_normal)
11434 (Fwindow_resize_apply): Don't use term subwindow in doc-strings.
11435 (delete_all_subwindows): Rename to delete_all_child_windows.
11436 (Fdelete_other_windows_internal, Fset_window_configuration):
11437 Call delete_all_child_windows instead of delete_all_subwindows.

11443 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
11444 This is also needed for porting to any host where GC_MARK_STACK is
11445 not GC_MAKE_GCPROS_NOOPS.
11446 (which_symbols): Use it.
11448 2011-11-07 Kenichi Handa <handa@m17n.org>

11461 * xmenu.c (cleanup_widget_value_tree): New function.
11462 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
11463 calling free_menubar_widget_value_tree directly (Bug#9830).

11468 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
11469 (window_box_width, window_box_left, window_box_left_offset)
11470 (window_box_right, window_box_right_offset): Declare extern.
11471 Otherwise, these inline functions do not conform to C99 and
11472 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
11473 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
11474 * intervals.c (adjust_intervals_for_insertion)
11475 (adjust_intervals_for_deletion): Now extern, because otherwise the
11476 extern inline functions 'offset_intervals' couldn't refer to it.
11477 (static_offset_intervals): Remove.
11478 (offset_intervals): Rewrite using the old contents of
11479 static_offset_intervals. The old version didn't conform to C99
11480 because an extern inline function contained a reference to an
11481 identifier with static linkage.
11483 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
11485 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

11491 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
11492 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
11493 return Qleft_to_right.

11500 (Fwindow_use_time, Fwindow_total_size, Fwindow_normal_size)
11501 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
11502 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
11503 (Fwindow_vscroll): Doc fix.
11504 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
11505 argument, since it makes no sense to pass a live window and for
11506 consistency with window-child.

11531 2011-11-05 Jan Djärv <jan.h.d@swipnet.se>
11533 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
11534 (unwind_create_frame): New function (Bug#9943).
11535 (Fx_create_frame): Restructure code to be more similar to the one in
11536 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
11537 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
11538 Move terminal->reference_count++ just before making the frame official
11541 * nsterm.m (x_free_frame_resources): New function.
11542 (x_destroy_window): Move code to x_free_frame_resources.
11544 * xfns.c (unwind_create_frame): Fix comment.
11545 (Fx_create_frame, x_create_tip_frame):
11546 Move terminal->reference_count++ just before making the frame
11547 official. Move initialization of image_cache_refcount and
11548 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

11678 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
11679 Not clear what it was for, and it causes various bugs. (Bug#9839)
11681 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11683 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
11684 possible random value that matches one of those tested as
11685 condition to clear the mouse face.
11687 2011-10-28 Chong Yidong <cyd@gnu.org>
11689 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
11691 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
11693 * window.c (make_window): Initialize phys_cursor_on_p.
11695 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
11697 * lisp.h (struct Lisp_Symbol): Update comments.
11699 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
11701 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
11703 2011-10-28 Eli Zaretskii <eliz@gnu.org>
11705 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
11706 <oslsachem@gmail.com> for helping to debug this.
11708 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
11709 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
11710 (g_b_init_get_glyph_outline_w): New static variables.
11711 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
11712 (GetGlyphOutlineW_Proc): New typedefs.
11713 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
11714 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
11716 (w32font_open_internal, compute_metrics):
11717 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
11718 instead of calling the "wide" APIs directly.
11720 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
11722 * w32.h (syms_of_w32font): Add prototype.
11724 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11726 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
11727 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
11728 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
11729 (Fmove_to_window_line): Doc fix.
11731 2011-10-27 Chong Yidong <cyd@gnu.org>
11733 * process.c (make_process): Set gnutls_state to NULL.
11735 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
11736 non-NULL, regardless of GNUTLS_INITSTAGE.
11737 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
11738 an error. Set process slots as soon as we allocate them.
11740 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
11742 2011-10-27 Chong Yidong <cyd@gnu.org>
11744 * gnutls.c (emacs_gnutls_deinit): New function.
11745 Deallocate credentials structures as well as calling gnutls_deinit.
11746 (Fgnutls_deinit, Fgnutls_boot): Use it.
11748 * process.c (make_process): Initialize GnuTLS credentials to NULL.
11749 (deactivate_process): Call emacs_gnutls_deinit.
11751 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
11753 * image.c (x_create_x_image_and_pixmap):
11754 * w32.c (sys_rename, w32_delayed_load):
11755 * w32font.c (fill_in_logfont):
11756 * w32reg.c (x_get_string_resource): Silence compiler warnings.
11758 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
11760 * w32fns.c (w32_default_color_map): New function,
11761 extracted from Fw32_default_color_map.
11762 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
11764 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
11766 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
11768 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
11770 * keyboard.c (test_undefined): New function (bug#9751).
11771 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
11773 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
11775 * sysdep.c (init_sys_modes): Fix the check for the controlling
11776 terminal (Bug#6649).
11778 2011-10-20 Eli Zaretskii <eliz@gnu.org>
11780 * dispextern.h (struct bidi_it): New member next_en_type.
11782 * bidi.c (bidi_line_init): Initialize the next_en_type member.
11783 (bidi_resolve_explicit_1): When next_en_pos is valid for the
11784 current character, check also for next_en_type being WEAK_EN.
11785 (bidi_resolve_weak): Don't enter the expensive loop if the current
11786 position is before next_en_pos. Record the bidi type of the first
11787 non-ET, non-BN character we find, in addition to its position.
11788 (bidi_level_of_next_char): Invalidate next_en_type when
11789 next_en_pos is over-stepped.
11791 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
11793 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
11794 * editfns.c: Rewrite current-time-zone so that it invokes
11795 the equivalent of (format-time-string "%Z") to get the time zone name.
11796 This fixes a bug when the time zone name contains characters that
11797 need converting from the system time locale to Emacs internal format.
11798 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
11799 that patch fixed format-time-string to do the conversion, but
11800 I forgot to fix current-time-zone.
11801 (format_time_string): New function, containing most of
11802 what Fformat_time_string used to contain.
11803 (Fformat_time_string): Rewrite in terms of format_time_string.
11804 This doesn't change this function's behavior.
11805 (current-time-zone): Rewrite to use format_time_string.
11806 This fixes the bug reported by Michael Schierl in
11807 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
11808 Jason Rumney's 2007-06-07 change worked around this bug, but
11810 * systime.h (tzname, timezone): Remove no-longer-used declarations.
11812 2011-10-19 Eli Zaretskii <eliz@gnu.org>
11814 * xdisp.c (start_display): If the character at POS is displayed
11815 via a display vector, reset IT->current.dpvec_index to zero.
11816 (try_window_reusing_current_matrix): If a line ends in a display
11817 vector or the next line starts in a display vector, continue
11818 redrawing the window even though the character position of
11819 start_row was reached.
11822 2011-10-18 Chong Yidong <cyd@gnu.org>
11824 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
11825 with nobreak-char-display too.
11827 2011-10-18 Eli Zaretskii <eliz@gnu.org>
11829 Fix part 3 of bug#9771.
11830 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
11831 (bidi_resolve_neutral): Don't enter the expensive loop looking for
11832 non-neutral characters if the current character is a paragraph
11833 separator (a.k.a. Newline). This avoids running the same
11834 expensive loop twice, once when we consume the preceding newline
11835 and the other time when the line actually needs to be displayed.
11836 Avoid the loop when we see neutrals on the base embedding level
11837 following a character whose directionality is the same as the
11838 paragraph's. This avoids running the expensive loop when a line
11839 ends in a long sequence of neutrals, like control characters.
11840 Add assertion against STRONG_AL type. Slightly rearrange code
11841 that determines the type of a neutral given the first non-neutral
11843 (bidi_level_of_next_char): Set next_en_pos to zero when
11844 invalidating its info.
11846 2011-10-17 Eli Zaretskii <eliz@gnu.org>
11848 * xdisp.c (push_display_prop): Determine whether to record string
11849 or buffer position by IT->string, not by IT->method. Allow
11850 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
11851 (move_it_vertically_backward): Don't look for character position
11852 immediately after the newline when in a continuation line.
11855 2011-10-15 Martin Rudalics <rudalics@gmx.at>
11857 * window.c (coordinates_in_window): Rewrite and delabelize
11858 vertical border check. (Bug#5357) (Bug#9618)
11860 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
11862 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
11863 errors in XSetWindowBorder (bug#9310).
11865 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
11867 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
11868 avoid crash when xmalloc overrun checking is enabled.
11870 2011-10-13 Eli Zaretskii <eliz@gnu.org>
11872 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
11873 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
11874 cursor motion with <left> and <right> arrow keys.
11876 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
11877 some callers set that themselves.
11879 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11881 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
11882 display string and the previous row comes from the same string and
11883 is empty. (Bug#9739) (Bug#9738)
11885 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
11887 * doc.c (get_doc_string): Encode file name (bug#9735).
11889 2011-10-12 Eli Zaretskii <eliz@gnu.org>
11891 * bidi.c (bidi_level_of_next_char):
11892 * xdisp.c (get_visually_first_element): Remove old incorrect
11893 comments regarding the Unicode Line Separator character.
11895 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
11897 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
11899 * alloc.c (Fgc_status): Do not access beyond zombies array
11900 boundary if nzombies > MAX_ZOMBIES.
11901 * alloc.c (dump_zombies): Add missing format specifier.
11903 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
11905 * xdisp.c (set_cursor_from_row): Simplify conditionals,
11906 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
11908 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
11909 Some packages use them to denote characters with modifiers.
11911 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
11913 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
11914 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
11915 matching a pp-number. Rename parameter var to var1.
11917 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
11919 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
11921 2011-10-08 Glenn Morris <rgm@gnu.org>
11923 * callint.c (Fcall_interactively): Give a more explicit error for the
11924 'c' case with a non-character input. (Bug#8479)
11926 2011-10-08 Eli Zaretskii <eliz@gnu.org>
11928 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
11930 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
11931 lines that are hscrolled on the left.
11933 * dispnew.c (buffer_posn_from_coords): Account for a possible
11934 presence of header-line. (Bug#4426)
11936 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
11938 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
11939 Don't advertise functionality which we discourage or doesn't work.
11941 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
11943 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
11944 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
11945 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
11946 this makes Emacs dump core during garbage collection on rare
11947 occasions. sizeof is obviously inferior to offsetof here, so
11948 stick with offsetof.
11949 (GC_POINTER_ALIGNMENT): New macro.
11950 (mark_memory): Omit 3rd (offset) arg; caller changed.
11951 Don't assume EMACS_INT alignment is the same as pointer alignment.
11953 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
11955 * keyboard.c (read_key_sequence_remapped): New var.
11956 (read_key_sequence): Compute remapping in the right buffer.
11957 (command_loop_1): Use read_key_sequence's remapping directly.
11959 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
11961 * dired.c (file_name_completion): Don't expand file name.
11962 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
11963 before checking file name handler.
11965 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
11966 they've been requested explicitly (bug#9591).
11968 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
11970 * keymap.c (Fsingle_key_description): Use make_specified_string
11971 instead of build_string to build string from push_key_description.
11974 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
11976 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
11977 This fixes a Y2038 bug on 64-bit hosts.
11978 * buffer.c (reset_buffer):
11979 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
11980 (Fclear_buffer_auto_save_failure):
11981 Use 0, not -1, to represent an unset failure time, since time_t
11982 might not be signed.
11984 Remove dependency on glibc malloc internals.
11985 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11986 Move back here from lisp.h, but with their new implementations.
11987 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11988 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
11989 * charset.c (charset_table_init): New static var.
11990 (syms_of_charset): Use it instead of xmalloc. This removes a
11991 dependency on glibc malloc internals. See Eli Zaretskii's comment in
11992 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
11993 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
11994 Move back to alloc.c.
11995 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
11996 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
11998 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
12000 * nsterm.m (windowDidResize): Call x_set_window_size only when
12001 ns_in_resize is true. Otherwise set pixelwidth/height and
12002 call change_frame_size (Bug#9628).
12004 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
12006 Port --enable-checking=all to Fedora 14 x86-64.
12007 * charset.c (syms_of_charset): Also account for glibc malloc's
12008 internal overhead when calculating the initial malloc maximum.
12010 Port --enable-checking=all to Fedora 14 x86.
12011 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12013 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
12014 (overrun_check_realloc, overrun_check_free):
12015 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
12016 That way, xmalloc returns a properly-aligned pointer even if
12017 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
12018 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
12019 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
12020 into account when calculating the initial malloc maximum.
12021 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
12022 Move here from alloc.c, so that charset.c can use it too.
12023 Properly align; the old code wasn't right for common 32-bit hosts
12024 when configured with --enable-checking=all.
12025 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
12026 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
12028 2011-09-29 Eli Zaretskii <eliz@gnu.org>
12030 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
12033 2011-09-28 Eli Zaretskii <eliz@gnu.org>
12035 * xdisp.c (compute_display_string_end): If there's no display
12036 string at CHARPOS, return -1.
12038 * bidi.c (bidi_fetch_char): When compute_display_string_end
12039 returns a negative value, treat the character as a normal
12040 character not covered by a display string. (Bug#9624)
12042 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
12044 * lread.c (Fread_from_string): Fix typo in docstring.
12046 2011-09-27 Eli Zaretskii <eliz@gnu.org>
12048 * xdisp.c (handle_invisible_prop): If invisible text ends on a
12049 newline, reseat the iterator instead of bidi-iterating there one
12050 character at a time. (Bug#9610)
12051 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
12052 TO_CHARPOS if the bidi iterator is at base embedding level.
12054 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
12056 * lread.c (readevalloop): Use correct code for NBSP.
12057 (read1): Likewise. (Bug#9608)
12059 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
12061 * dbusbind.c (Fdbus_register_signal): When service is not
12062 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
12064 2011-09-25 Glenn Morris <rgm@gnu.org>
12066 * buffer.c (truncate-lines): Doc fix.
12068 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
12070 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
12071 (Fset_window_next_buffers): Doc fix.
12073 2011-09-24 Glenn Morris <rgm@gnu.org>
12075 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
12077 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
12079 Fix minor problems found by static checking.
12080 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
12081 * indent.c (Fvertical_motion): Fix == vs = typo.
12083 2011-09-24 Eli Zaretskii <eliz@gnu.org>
12085 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
12086 Default value is now t. Doc fix.
12088 * indent.c (Fvertical_motion): Compute and apply the overshoot
12089 logic when moving up, not only when moving down. Fix the
12090 confusing name and values of the it_overshoot_expected variable;
12091 logic changes accordingly. (Bug#9254) (Bug#9549)
12093 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
12094 CHARPOS is covered by a display string which includes newlines.
12095 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
12096 is covered by a display string with embedded newlines.
12098 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
12100 * dbusbind.c (Fdbus_register_signal): Add match rule to
12101 Vdbus_registered_objects_table. (Bug#9581)
12102 (Fdbus_register_method, Vdbus_registered_objects_table):
12105 2011-09-24 Jim Meyering <meyering@redhat.com>
12107 do not ignore write error for any output size
12108 The previous change was incomplete.
12109 While it makes emacs --batch detect the vast majority of stdout
12110 write failures, errors were still ignored whenever the output size is
12111 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
12112 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
12113 && echo FAIL: ignored write error
12114 FAIL: ignored write error
12115 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
12116 && echo FAIL: ignored write error
12117 FAIL: ignored write error
12118 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
12120 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
12122 * emacs.c (Fkill_emacs): In noninteractive mode exit
12123 non-successfully if a write error occurred on stdout. (Bug#9574)

12127 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
12130 * dispextern.h (struct it): Update the comment documenting what
12133 2011-09-20 Eli Zaretskii <eliz@gnu.org>
12135 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
12136 a display string, extend search for cursor position to end of row.
12137 (find_row_edges): If the row ends in a newline from a display
12138 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
12139 Handle the case of a display string with multiple newlines.
12140 (Fcurrent_bidi_paragraph_direction): Fix search for previous
12141 non-empty line. Fixes confusing cursor motion with arrow keys at
12142 the beginning of a line that starts with whitespace.
12144 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
12146 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
12149 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
12151 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
12152 boolean (Bug#9154).
12154 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12156 * xdisp.c (display_line): Record maximum and minimum buffer
12157 positions even if no glyphs were produced (e.g., by a zero-width
12158 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
12159 buffer positions that will be removed from the glyph row because
12161 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
12162 column is beyond frame width: don't subtract 1 "pixel" when
12163 computing width of the stretch.
12164 (reseat_at_next_visible_line_start): Undo the change made on
12165 2011-09-17 that saved paragraph information and restored it after
12166 the call to `reseat'. (Bug#9545)
12168 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12170 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
12171 and turn window cursor on if cleared (Bug#9415).
12173 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
12175 * search.c (boyer_moore): Take unibyte characters from pattern
12176 literally. (Bug#9458)
12178 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12180 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
12182 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
12184 Fix minor problem found by static checking.
12185 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
12186 initialized, to pacify gcc -Wuninitialized.
12188 * fileio.c: Report proper errno when syscall falls.
12189 (Finsert_file_contents): Save and restore errno,
12190 so that report_file_error outputs the correct diagnostic.
12191 (Fwrite_region) [CLASH_DETECTION]: Likewise.
12193 2011-09-18 Eli Zaretskii <eliz@gnu.org>
12195 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
12197 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12199 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
12200 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
12202 2011-09-17 Eli Zaretskii <eliz@gnu.org>
12204 * xdisp.c (reseat_at_next_visible_line_start): Keep information
12205 about the current paragraph and restore it after the call to reseat.
12207 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
12208 (bidi_find_paragraph_start): Search back for paragraph beginning
12209 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
12210 (bidi_move_to_visually_next): Only trigger paragraph-related
12211 computations when the last character is a newline or at EOB, not
12212 just any NEUTRAL_B. (Bug#9470)
12214 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
12215 truncated lines if point is covered by a display string. (Bug#9524)
12217 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
12219 * xselect.c: Relax test for outgoing X longs (Bug#9498).
12220 (cons_to_x_long): New function.
12221 (lisp_data_to_selection_data): Use it. Correct the test for
12222 short-versus-long data; it was negated. Break out of vector
12223 loop, for efficiency, when a long datum is discovered.
12225 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
12227 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
12229 2011-09-16 Eli Zaretskii <eliz@gnu.org>
12231 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
12232 GCC PR/17406) by declaring this function with external scope.
12234 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12236 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
12237 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
12239 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
12241 * editfns.c (Fformat): Correctly handle text properties on "%%".
12243 2011-09-15 Eli Zaretskii <eliz@gnu.org>
12245 * xterm.c (x_draw_composite_glyph_string_foreground):

12247 * term.c (encode_terminal_code):
12248 * composite.c (composition_update_it, get_composition_id):
12249 * xdisp.c (get_next_display_element)
12250 (fill_composite_glyph_string): Add comments about special meaning
12251 of TAB characters in a composition.
12253 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
12255 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
12256 This occurs when processing a multibyte format.
12257 Problem reported by Wolfgang Jenker.
12259 2011-09-15 Johan Bockgård <bojohan@gnu.org>
12261 * xdisp.c (try_cursor_movement): Only check for exact match if
12262 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
12264 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12266 Remove unused external symbols.
12267 * dispextern.h (calc_pixel_width_or_height): Remove decl.
12268 * xdisp.c (calc_pixel_width_or_height): Now static.
12269 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
12270 * indent.c (check_display_width):
12271 * w32term.c: Fix comment to match code.
12272 * xterm.c, xterm.h (x_catching_errors): Remove.
12274 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
12276 * xselect.c: Use signed conversions more consistently (Bug#9498).
12277 (selection_data_to_lisp_data): Assume incoming selection data are
12278 signed integers, not unsigned. This is to be consistent with
12279 outgoing selection data, which was modified to use signed integers
12280 in as part of the fix to Bug#9196 in response to Jan D.'s comment
12281 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
12282 expects long, not unsigned long.
12284 2011-09-14 Eli Zaretskii <eliz@gnu.org>
12286 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
12287 computation of loop end. Reported by Johan Bockgård
12290 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
12292 * frame.c (Fother_visible_frames_p): Function deleted.
12294 2011-09-12 Eli Zaretskii <eliz@gnu.org>
12296 * indent.c (compute_motion): Process display vector front to back
12297 rather than the other way around. (Bug#2496)
12299 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
12301 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
12303 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
12305 * minibuf.c (Fread_from_minibuffer): Doc fix.
12307 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12309 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
12310 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
12312 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
12314 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
12315 value for non-existent files.
12317 2011-09-11 Eli Zaretskii <eliz@gnu.org>
12319 * fileio.c (Finsert_file_contents): If the file cannot be opened,
12320 set its "size" to -1. This will set the modtime_size field of
12321 the corresponding buffer to -1, which is what
12322 verify-visited-file-modtime expects for files that do not exist.
12325 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
12327 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
12329 * lisp.h: ... from here. push_key_description is no longer
12330 defined in keyboard.c, so its declaration should not be in
12331 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
12332 logically belongs with push_key_description.
12334 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
12336 * buffer.h: Include <sys/types.h> instead of <time.h>.
12337 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
12338 Problem reported by Herbert J. Skuhra.
12340 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
12342 * xml.c (parse_region): Make the parsing work for
12343 non-comment-starting XML files again (bug#9144).
12345 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
12347 * image.c (gif_load): Fix calculation of bottom and right corner.
12350 2011-09-10 Eli Zaretskii <eliz@gnu.org>
12352 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
12353 redisplay in small windows.
12355 2011-09-09 Eli Zaretskii <eliz@gnu.org>
12357 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
12359 2011-09-08 Martin Rudalics <rudalics@gmx.at>
12361 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
12362 Operate on live windows only.
12364 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
12366 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
12368 2011-09-07 Eli Zaretskii <eliz@gnu.org>
12370 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
12371 only under bidi iteration.
12373 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
12375 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
12377 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12379 isnan: Fix porting problem to Solaris 10 with bundled gcc.
12380 Without this fix, the command to link temacs failed due to an
12381 undefined symbol __builtin_isnan. This is because
12382 /usr/include/iso/math_c99.h #defines isnan(x) to
12383 __builtin_isnan(x), but the bundled gcc, which identifies itself
12384 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
12386 * floatfns.c (isnan): #undef, and then #define to a clone of
12388 (Fisnan): Always define, since it's always available now.
12389 (syms_of_floatfns): Always define isnan at the Lisp level.
12391 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12393 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
12395 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
12397 * fileio.c: Fix bugs with large file offsets (Bug#9428).
12398 The previous code assumed that file offsets (off_t values) fit in
12399 EMACS_INT variables, which is not true on typical 32-bit hosts.
12400 The code messed up by falsely reporting buffer overflow in cases
12401 such as (insert-file-contents "big" nil 1 2) into an empty buffer
12402 when "big" contains more than 2**29 bytes, even though this
12403 inserts just one byte and does not overflow the buffer.
12404 (Finsert_file_contents): Store file offsets as off_t
12405 values, not as EMACS_INT values. Check for overflow when
12406 converting between EMACS_INT and off_t. When checking for
12407 buffer overflow or for overlap, take the offsets into account.
12408 Don't use EMACS_INT for small values where int suffices.
12409 When checking for overlap, fix a typo: ZV was used where
12410 ZV_BYTE was intended.
12411 (Fwrite_region): Don't assume off_t fits into 'long'.
12412 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
12414 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
12416 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
12418 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12420 sprintf-related integer and memory overflow issues (Bug#9412).
12422 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
12423 (esprintf, exprintf, evxprintf): New functions.
12424 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
12425 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
12426 (modify_event_symbol): Do not assume that the length of
12427 name_alist_or_stem is safe to alloca and fits in int.
12428 (Fexecute_extended_command): Likewise for function name and binding.
12429 (Frecursion_depth): Wrap around reliably on integer overflow.
12430 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
12431 since some callers pass EMACS_INT values.
12432 (Fsingle_key_description): Don't crash if symbol name contains more
12433 than MAX_ALLOCA bytes.
12434 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
12435 (get_minibuffer): Arg is now EMACS_INT, not int.
12436 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
12437 (esprintf, exprintf, evxprintf): New decls.
12438 * window.h (command_loop_level, minibuf_level): Reflect API changes.
12440 * dbusbind.c (signature_cat): New function.
12441 (xd_signature, Fdbus_register_signal):
12442 Do not overrun buffer; instead, report string overflow.
12444 * dispnew.c (add_window_display_history): Don't overrun buffer.
12445 Truncate instead; this is OK since it's just a log.
12447 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
12448 even if the time zone offset is outlandishly large.
12449 Don't mishandle offset == INT_MIN.
12451 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
12452 when creating daemon; the previous buffer-overflow check was incorrect.
12454 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
12455 which has the guts of the old verror function.
12457 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
12458 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
12460 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
12461 (font_unparse_xlfd): Don't blindly alloca long strings.
12462 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
12463 fits in int, when using sprintf. Use single snprintf to count
12464 length of string rather than counting it via multiple sprintfs;
12465 that's simpler and more reliable.
12466 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
12467 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
12468 sprintf, in case result does not fit in int.
12470 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
12471 (fontset_from_font): Print it.
12473 * frame.c (tty_frame_count): Now printmax_t, not int.
12474 (make_terminal_frame, set_term_frame_name): Print it.
12475 (x_report_frame_params): In X, window IDs are unsigned long,
12476 not signed long, so print them as unsigned.
12477 (validate_x_resource_name): Check for implausibly long names,
12478 and don't assume name length fits in 'int'.
12479 (x_get_resource_string): Don't blindly alloca invocation name;
12480 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
12483 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
12484 (xg_check_special_colors, xg_set_geometry):
12485 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
12487 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
12488 Use esprintf, not sprintf, in case result does not fit in int.
12490 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12491 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
12492 it as a large positive number.
12493 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
12494 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
12496 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
12497 in case result does not fit in int.
12499 * print.c (float_to_string): Detect width overflow more reliably.
12500 (print_object): Make sprintf buffer a bit bigger, to avoid potential
12501 buffer overrun. Don't assume list length fits in 'int'. Treat
12502 print length of 0 as 0, not as infinity; to be consistent with other
12503 uses of print length in this function. Don't overflow print length
12504 index. Don't assume hash table size fits in 'long', or that
12505 vectorlike size fits in 'unsigned long'.
12507 * process.c (make_process): Use printmax_t, not int, to format
12508 process-name gensyms.
12510 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
12512 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
12513 to avoid potential buffer overrun.
12515 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
12516 if X resource line is longer than 512 bytes.
12518 * xfns.c (x_window): Make sprintf buffer a bit bigger
12519 to avoid potential buffer overrun.
12521 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
12523 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
12525 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
12527 Integer overflow fixes for scrolling, etc.
12528 Without these, Emacs silently mishandles large integers sometimes.
12529 For example, "C-u 4294967297 M-x recenter" was treated as if
12530 it were "C-u 1 M-x recenter" on a typical 64-bit host.
12532 * xdisp.c (try_window_id): Check Emacs fixnum range before
12533 converting to 'int'.
12535 * window.c (window_scroll_line_based, Frecenter):
12536 Check that an Emacs fixnum is in range before assigning it to 'int'.
12537 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
12538 values converted from Emacs fixnums.
12539 (Frecenter): Don't wrap around a line count if it is out of 'int'
12540 range; instead, treat it as an extreme value.
12541 (Fset_window_configuration, compare_window_configurations):
12542 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
12544 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
12545 that can exceed INT_MAX. Check that EMACS_INT value is in range
12546 before assigning it to the (possibly-narrower) index.
12547 (match_limit): Don't assume that a fixnum can fit in 'int'.
12549 * print.c (print_object): Use ptrdiff_t, not int, for index that can
12552 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
12553 (Fvertical_motion): Don't wrap around LINES values that don't fit
12554 in 'int'. Instead, treat them as extreme values. This is good
12555 enough for windows, which can't have more than INT_MAX lines anyway.
12557 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
12559 * Require libxml/parser.h to avoid compilation warning.
12561 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
12563 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
12564 since this reportedly can destroy thread storage.
12566 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
12568 * syntax.c (find_defun_start): Update all cache variables if
12569 exiting early (Bug#9401).
12571 2011-08-30 Eli Zaretskii <eliz@gnu.org>
12573 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
12575 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
12576 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
12577 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
12579 * term.c (tty_append_glyph): New function.
12580 (produce_stretch_glyph): Static function and its prototype deleted.

12587 * image.c (parse_image_spec): Check for nonnegative, not for positive,
12588 when checking :margin (Bug#9390).
12589 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
12590 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
12591 so that the name doesn't mislead. All uses changed.
12593 2011-08-28 Johan Bockgård <bojohan@gnu.org>
12595 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
12598 2011-08-27 Eli Zaretskii <eliz@gnu.org>

12601 position beyond to_charpos, if we are scanning backwards.
12602 (move_it_vertically_backward): When DY == 0, make sure we get to
12603 the first character in the line after the newline.
12605 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
12607 * ccl.c: Improve and simplify overflow checking (Bug#9196).
12608 (ccl_driver): Do not generate an out-of-range pointer.
12609 (Fccl_execute_on_string): Remove unnecessary check for
12610 integer overflow, noted by Stefan Monnier in
12611 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
12612 Remove a FIXME that didn't need fixing.
12613 Simplify the newly-introduced buffer reallocation code.
12615 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
12617 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
12619 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
12621 Integer and memory overflow issues (Bug#9196).
12623 * doc.c (get_doc_string): Rework so that
12624 get_doc_string_buffer_size is the actual buffer size, rather than
12625 being 1 less than the actual buffer size; this makes xpalloc more
12628 * image.c (x_allocate_bitmap_record, cache_image):
12629 * xselect.c (Fx_register_dnd_atom):
12630 Simplify previous changes by using xpalloc.
12632 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
12633 since either will do and ptrdiff_t is convenient with xpalloc.
12635 * charset.c (charset_table_size)
12636 (struct charset_sort_data.priority): Now ptrdiff_t.
12637 (charset_compare): Don't overflow if priorities differ greatly.
12638 (Fsort_charsets): Don't assume list length fits in int.
12639 Check for size-calculation overflow when allocating sort data.
12640 (syms_of_charset): Allocate an initial charset table that is
12641 just under 64 KiB, to avoid problems with glibc malloc and mmap.
12643 * cmds.c (internal_self_insert): Check for size-calculation overflow.
12645 * composite.h (struct composition.glyph_len): Now int, not unsigned.
12646 The actual value is always <= INT_MAX, and leaving it unsigned made
12647 overflow checking harder.
12649 * dispextern.h (struct glyph_matrix.rows_allocated)
12650 (struct face_cache.size): Now ptrdiff_t, for convenience in use
12651 with xpalloc. The values are still always <= INT_MAX.
12653 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
12655 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
12656 (SAFE_NALLOCA): New macro.

12659 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
12660 (set_cache_region, invalidate_region_cache)
12661 (revalidate_region_cache, know_region_cache, region_cache_forward)
12662 (region_cache_backward, pp_cache):
12663 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
12664 so that ptrdiff_t * can be passed to xpalloc.
12665 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
12666 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
12667 (pp_cache): Don't assume cache_len fits in int.
12668 * region-cache.h: Adjust extern decls to match.
12670 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
12671 EMACS_INT, since either will do, for xpalloc.
12673 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
12674 (xnmalloc, xnrealloc, xpalloc): New functions.
12676 * bidi.c (bidi_shelve_header_size): New constant.
12677 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
12678 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
12680 * bidi.c (bidi_cache_shrink):
12681 * buffer.c (overlays_at, overlays_in, record_overlay_string)
12683 Don't update size of array until after memory allocation succeeds,
12684 because xmalloc/xrealloc may not return.
12685 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
12686 now that we have proper integer overflow checking.
12687 (record_overlay_string, overlay_strings): Catch overflows when
12688 calculating size of overlay_str_buf.
12690 * callproc.c (Fcall_process): Check for size overflow when
12691 calculating size of args2.
12692 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
12693 Normally we prefer signed values, but sticking with ptrdiff_t would
12694 require adding more-complicated checks.
12696 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
12697 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
12698 Redo buffer-overflow calculations to avoid integer overflow.
12699 Add a FIXME comment where memory seems to be over-allocated.
12701 * character.c (Fstring): Check for size-calculation overflow.
12703 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
12704 unnecessary integer overflow. Check for size overflow.
12705 (encode_coding_object): Don't update size until xmalloc succeeds.
12707 * composite.c (get_composition_id): Check for overflow in glyph
12708 length calculations.
12710 Integer and memory overflow fixes for display code.
12711 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
12712 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)

12725 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
12726 (get_doc_string): Check for size calculation overflow.
12727 Don't update size until allocation succeeds.
12728 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
12729 EMACS_INT, where ptrdiff_t will do.
12730 (Fsubstitute_command_keys): Check for string overflow.
12732 * editfns.c (set_time_zone_rule): Don't assume environment length
12734 (message_length): Now ptrdiff_t, not int.
12735 (Fmessage_box): Don't update size until allocation succeeds.
12736 Don't assume message length fits in int.
12737 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
12739 * emacs.c (main): Do not reallocate argv, since there is a null at
12740 the end that can be overwritten, and this way there's no need to
12741 worry about size-calculation overflow.
12742 (sort_args): Check for size-calculation overflow.
12744 * eval.c (init_eval_once, grow_specpdl): Don't update size until
12746 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
12748 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
12749 (x_set_scroll_bar_width, x_figure_window_size):
12750 Check for integer overflow.
12751 (x_set_alpha): Do not assume XINT fits in int.
12753 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
12754 This is for the members text_lines, text_cols, total_lines, total_cols,
12755 where the system imposes an 'int' limit.
12757 * fringe.c (Fdefine_fringe_bitmap):
12758 Don't update size until alloc works.
12760 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
12761 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
12763 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
12764 Check for size-calculation overflow.
12765 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
12766 do, as we prefer signed integers.
12767 (id_to_widget.max_size, id_to_widget.used)
12768 (xg_store_widget_in_map, xg_remove_widget_from_map)
12769 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
12770 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
12771 Use and return ptrdiff_t, not int.
12772 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
12773 * gtkutil.h: Change prototypes to match the above.
12775 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
12776 are duplicate now that they've been promoted to lisp.h.
12777 (x_allocate_bitmap_record, x_alloc_image_color)
12778 (make_image_cache, cache_image, xpm_load):

12790 Use ptrdiff_t, not int, to count maps.
12791 (read_char_minibuf_menu_prompt): Check for overflow in size
12792 calculations. Don't update size until allocation succeeds.
12793 Redo calculations to avoid overflow.
12794 * keyboard.h: Change prototypes to match the above.
12796 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,

12822 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
12823 for command line length. Do not attempt to address one before the
12824 beginning of an array, as that's not portable.
12826 * term.c (max_frame_lines): Remove; unused.
12827 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
12829 (encode_terminal_code, calculate_costs): Check for size
12830 calculation overflow.

12836 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
12837 subtracting pointers.

12852 Use ptrdiff_t, not int, for sizes.
12853 (Finternal_make_lisp_face, cache_face):
12854 Check for size calculation overflow.
12855 (cache_face): Treat size calculation overflows as if they were
12856 memory exhaustion (the usual treatment), rather than aborting.
12858 * xfns.c (x_encode_text, x_set_name_internal)
12859 (Fx_change_window_property): Use ptrdiff_t, not int, to count
12860 sizes, since they can exceed INT_MAX in size. Check for size
12861 calculation overflow.
12863 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
12864 (xg_select): Check for size calculation overflow.
12865 Don't update size until alloc done.
12867 * xrdb.c (get_environ_db): Don't assume path length fits in int,
12868 as sprintf is limited to int lengths.
12870 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
12871 (X_LONG_MIN): New macros.
12872 Use them to make the following changes clearer.
12873 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
12874 This change doesn't affect the value now, but it may help remind
12875 future maintainers not to raise the value too much later.
12876 (SELECTION_QUANTUM): Remove, replacing with ...
12877 (selection_quantum): ... new function, which avoids overflow.
12879 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
12880 assumption that selection length fits in 'int'.

12893 (lisp_data_to_selection_data, x_property_data_to_lisp):

12895 (x_get_window_property, receive_incremental_selection)
12896 (lisp_data_to_selection_data, Fx_register_dnd_atom):
12897 Don't store size until memory allocation succeeds.
12898 (x_get_window_property): Plug memory leak on memory exhaustion.
12899 Don't double-block input; malloc is safe here. Don't assume 2**34
12900 - 4 fits in unsigned long. Add an xassert to check
12901 XGetWindowProperty overflow. Be more careful about overflow
12902 calculations, and distinguish size from memory overflow better.
12903 (receive_incremental_selection): When tracing, don't assume
12904 unsigned int is less than INT_MAX.
12905 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
12906 harmful) conversions of unsigned short to int.
12907 (lisp_data_to_selection_data): Don't assume that integers
12908 in the range -65535 through -1 fit in an X unsigned short.
12909 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
12910 result parameters unless successful. Rely on cons_to_unsigned
12911 to report problems with elements; the old code wasn't right anyway.
12912 (x_check_property_data): Check for int overflow; we cannot use
12913 a wider type due to X limits.
12914 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

12946 * lisp.h (hash_lookup, hash_put):
12947 * minibuf.c (Ftest_completion):
12948 Use ptrdiff_t for hash table indexes, not int (which is too
12949 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
12950 32-bit --with-wide-int hosts).
12952 * charset.c (Fdefine_charset_internal): Check for integer overflow.
12953 Add a FIXME comment about memory leaks.
12954 (syms_of_charset): Don't assume xmalloc returns.

12961 with outlandish widths.
12962 * character.h (sanitize_tab_width): Rename from sanitize_width,
12963 now that we have two such functions. All uses changed.
12964 (sanitize_char_width): New inline function.
12966 Don't assume that tab-width fits in int.

12974 * fileio.c: Integer overflow issues with file modes.
12975 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
12977 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

12984 exceed limits imposed by XClientMessageEvent, as well as the usual
12985 ptrdiff_t and size_t limits.
12987 * keyboard.c: Overflow, signedness and related fixes.
12988 (make_lispy_movement): Use same integer type in forward decl
12989 that is used in the definition.
12990 (read_key_sequence, keyremap_step):
12991 Change bufsize argument back to int, undoing my 2011-03-30 change.
12992 We prefer signed types, and int is wide enough here.
12993 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
12994 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
12995 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
12996 length, not size_t. Use ptrdiff_t for index, not int.
12997 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
12998 possibility of integer overflow.

13026 Prefer int to unsigned where either will do.
13027 (tiff_handler): New function, combining the cores of the
13028 old tiff_error_handler and tiff_warning_handler.
13029 This function is rewritten to use vsnprintf and thereby avoid
13030 stack buffer overflows. It uses only the features of vsnprintf
13031 that are common to both POSIX and native Microsoft.
13032 (tiff_error_handler, tiff_warning_handler): Use it.
13033 (tiff_load, gif_load, imagemagick_load_image):
13034 Don't assume :index value fits in 'int'.

13036 (imagemagick_load_image): Check that crop parameters fit into
13037 the integer types that MagickCropImage accepts. Don't assume
13038 Vimagemagick_render_type has a nonnegative value. Don't assume
13039 size_t fits in 'long'.
13040 (gs_load): Use printmax_t to print the widest integers possible.
13041 Check for integer overflow when computing image height and width.

13054 (handle_single_display_spec): If the display spec is of the form
13055 `(space ...)', and specifies display in the text area, return 2
13057 (try_cursor_movement): Check for the need to scroll more
13058 accurately, and prefer exact match for point under bidi.
13059 Don't advance `row' beyond the last row of the window.
13061 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
13062 into disp_prop; all users changed.

13077 buffers, return left-to-right.
13078 (set_cursor_from_row): Consider candidate row a win if its glyph
13079 represents a newline and point is on that newline. Fixes cursor
13080 positioning on the newline at EOL of R2L text within L2R
13081 paragraph, and vice versa.
13082 (try_cursor_movement): Check continued rows, in addition to
13083 continuation rows. Fixes unwarranted scroll when point enters a
13084 continued line of R2L text within an L2R paragraph, or vice versa.
13085 (cursor_row_p): Consider the case of point being equal to
13086 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
13087 from the end of a short line to the beginning of a continued line
13088 of R2L text within L2R paragraph.

13110 2011-08-23 Eli Zaretskii <eliz@gnu.org>
13112 * xdisp.c (redisplay_window): When computing centering_position,
13113 account for the height of the header line. (Bug#8874)
13115 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
13116 instead of CHAR_TO_BYTE. Fixes a crash when a completion
13117 candidate is selected by the mouse, and that candidate has a
13118 composed character under the mouse.
13120 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
13121 coordinates reported by pos-visible-in-window-p for a composed
13122 character in column zero.
13124 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

13131 consider it a hit if to_charpos is anywhere in the range of the
13132 composed buffer positions.
13134 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
13136 * image.c (gif_load): Don't assume that each subimage has the same
13137 dimensions as the base image. Handle disposal method that is
13138 "undefined" by the gif spec (Bug#9335).
13140 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
13142 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

13147 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
13148 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
13149 from an Org mode buffer to a Speedbar frame.
13151 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
13152 a composition, take its buffer position from IT->cmp_it.charpos.
13153 Fixes cursor positioning at the beginning of a line that begins
13154 with a composed character.
13156 2011-08-18 Eli Zaretskii <eliz@gnu.org>
13158 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
13159 character bidirectional type, use STRONG_L instead. Fixes crashes
13160 in a buffer produced by `describe-categories'.
13162 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
13163 members before the level stack, so they would be saved and
13164 restored when copying iterator state. Fixes incorrect reordering
13165 around TABs covered by display properties.
13167 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
13169 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

13255 * nsterm.m (sendEvent): If event is NSApplicationDefined and
13256 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
13257 the event loop (Bug#7276).

13283 (Fnetwork_interface_list): Allocate in increments of bytes instead
13284 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
13285 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct

13300 buffer/string position, to be restored by pop_it. Fix flags in
13301 the iterator structure wrt the object coming from a display
13302 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
13303 properties. (Bug#9284)

13480 (x_set_background_color): Likewise.
13482 * nsmenu.m (-setText): Size tooltip dimensions precisely to
13483 contents (Bug#9176).
13484 (EmacsTooltip -init): Remove bezels and add shadows to
13487 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
13488 or scroll bar (Bug#8470).
13490 * nsfont.m (nsfont_open): Remove assignment to voffset and
13491 unnecessary vars hshink, expand, hd, full_height, min_height.
13492 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
13494 * nsterm.h (nsfont_info): Remove voffset field.
13496 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
13498 Implement strike-through and overline on NextStep (Bug#8863).
13500 * nsfont.m (nsfont_open): Use underline position provided by font,
13501 instead of hard-coded value of 2.
13502 (nsfont_draw): Call ns_draw_text_decoration instead.
13504 * nsterm.h: Add declaration for ns_draw_text_decoration.
13506 * nsterm.m (ns_draw_text_decoration): New function for drawing
13507 underline, overline, and strike-through.
13508 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
13509 ns_draw_text_decoration. Change treatment of cursor drawing to
13510 accommodate underlining, etc.
13512 2011-07-28 Eli Zaretskii <eliz@gnu.org>
13514 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
13517 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13519 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
13520 Without this fix, if a signal arrives just after memory fills up,
13521 'malloc' might be invoked reentrantly.
13523 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
13524 In other words, assume that every image size is allowed, on non-X
13525 hosts. This assumption is probably wrong, but it lets Emacs compile.
13527 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
13529 * regex.c (re_iswctype): Convert return values to boolean.
13531 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
13533 * xdisp.c (compute_display_string_pos): Don't use cached display
13534 string position if the buffer had its restriction changed.
13537 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13539 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
13541 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
13543 Integer signedness and overflow and related fixes. (Bug#9079)
13545 * bidi.c: Integer size and overflow fixes.
13546 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
13547 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
13548 (bidi_cache_find_level_change, bidi_cache_ensure_space)
13549 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
13550 (bidi_find_other_level_edge):
13551 Use ptrdiff_t instead of EMACS_INT where either will do.
13552 This works better on 32-bit hosts configured --with-wide-int.
13553 (bidi_cache_ensure_space): Check for size-calculation overflow.
13554 Use % rather than repeated addition, for better worst-case speed.
13555 Don't set bidi_cache_size until after xrealloc returns, because it
13557 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
13558 (bidi_cache_ensure_space): Also check that the bidi cache size
13559 does not exceed that of the largest Lisp string or buffer. See Eli
13560 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
13562 * alloc.c (__malloc_size_t): Remove.
13563 All uses replaced by size_t. See Andreas Schwab's note
13564 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
13566 * image.c: Improve checking for integer overflow.
13567 (check_image_size): Assume that f is nonnull, since
13568 it is always nonnull in practice. This is one less thing to
13569 worry about when checking for integer overflow later.
13570 (x_check_image_size): New function, which checks for integer
13571 overflow issues inside X.
13572 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
13573 This removes the need for a memory_full check.
13574 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
13575 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
13576 (xbm_read_bitmap_data): Change locals back to 'int', since
13577 their values must fit in 'int'.
13578 (xpm_load_image, png_load, tiff_load):
13579 Invoke x_create_x_image_and_pixmap earlier,
13580 to avoid much needless work if the image is too large.
13581 (tiff_load): Treat overly large images as if
13582 x_create_x_image_and_pixmap failed, not as malloc failures.
13583 (gs_load): Use x_check_image_size.
13585 * gtkutil.c: Omit integer casts.
13586 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
13587 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
13589 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
13591 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
13592 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
13593 would wrongly return t on a 64-bit host.
13595 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
13596 The plain *_OVERFLOW macros run afoul of GCC bug 49705
13597 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
13598 and therefore cause GCC to emit a bogus diagnostic in some cases.
13600 * image.c: Integer signedness and overflow and related fixes.
13601 This is not an exhaustive set of fixes, but it's time to
13602 record what I've got.
13603 (lookup_pixel_color, check_image_size): Remove redundant decls.
13604 (check_image_size): Don't assume that arbitrary EMACS_INT values
13605 fit in 'int', or that arbitrary 'double' values fit in 'int'.
13606 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
13607 (tiff_load, imagemagick_load_image):
13608 Check for overflow in size calculations.
13609 (x_create_x_image_and_pixmap): Remove unnecessary test for
13610 xmalloc returning NULL; that can't happen.
13611 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
13612 (xpm_color_bucket): Use better integer hashing function.
13613 (xpm_cache_color): Don't possibly over-allocate memory.
13614 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
13615 (gif_memory_source):
13616 Use ptrdiff_t, not int or size_t, to record sizes.
13617 (png_load): Don't assume values greater than 2**31 fit in 'int'.
13618 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
13619 either works, as we prefer signed integers.
13620 (tiff_read_from_memory, tiff_write_from_memory):
13621 Return tsize_t, not size_t, since that's what the TIFF API wants.
13622 (tiff_read_from_memory): Don't fail simply because the read would
13623 go past EOF; instead, return a short read.
13624 (tiff_load): Omit no-longer-needed casts.
13625 (Fimagemagick_types): Don't assume size fits into 'int'.
13627 Improve hashing quality when configured --with-wide-int.
13628 * fns.c (hash_string): New function, taken from sxhash_string.
13629 Do not discard information about ASCII character case; this
13630 discarding is no longer needed.
13631 (sxhash-string): Use it. Change sig to match it. Caller changed.
13632 * lisp.h: Declare it.
13633 * lread.c (hash_string): Remove, since we now use fns.c's version.
13634 The fns.c version returns a wider integer if --with-wide-int is
13635 specified, so this should help the quality of the hashing a bit.
13637 * emacs.c: Integer overflow minor fix.
13638 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
13639 Define only if GNU_LINUX.
13640 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
13642 * dispnew.c: Integer signedness and overflow fixes.
13643 Remove unnecessary forward decls, that were a maintenance hassle.
13644 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
13646 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
13647 (scrolling_window): Use ptrdiff_t, not int, for byte count.
13648 (prepare_desired_row, line_draw_cost):
13649 Use int, not unsigned, where either works.
13650 (save_current_matrix, restore_current_matrix):
13651 Use ptrdiff_t, not size_t, where either works.
13652 (init_display): Check for overflow more accurately, and without
13653 relying on undefined behavior.
13655 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
13656 Remove, replacing with the new symbols in lisp.h. All uses changed.
13657 * fileio.c (make_temp_name):
13658 * filelock.c (lock_file_1, lock_file):
13659 * xdisp.c (message_dolog):
13660 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
13661 Use pMd etc. instead.
13662 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
13663 replacing the pWIDE etc. symbols removed from editfns.c.
13665 * keyboard.h (num_input_events): Now uintmax_t.
13666 This is (very slightly) less likely to mess up due to wraparound.
13669 * buffer.c: Integer signedness fixes.
13670 (alloc_buffer_text, enlarge_buffer_text):
13671 Use ptrdiff_t rather than size_t when either will do, as we prefer
13674 * alloc.c: Integer signedness and overflow fixes.
13675 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
13676 (__malloc_size_t): Default to size_t, not to int.
13677 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
13678 (Fgarbage_collect, mark_object_loop_halt, mark_object):
13679 Prefer ptrdiff_t to size_t when either would do, as we prefer
13681 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
13682 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
13683 Now const. Initialize with values that are in range even if char
13685 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
13686 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
13687 These functions do the right thing with sizes > 2**32.
13688 (check_depth): Now ptrdiff_t, not int.
13689 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
13690 Adjust to new way of storing sizes. Check for size overflow bugs
13692 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
13693 slightly wrong anyway, as it missed one instance of
13694 XMALLOC_OVERRUN_CHECK_OVERHEAD.
13695 (refill_memory_reserve): Omit needless cast to size_t.
13696 (mark_object_loop_halt): Mark as externally visible.
13698 * xselect.c: Integer signedness and overflow fixes.
13699 (Fx_register_dnd_atom, x_handle_dnd_message):
13700 Use ptrdiff_t, not size_t, since we prefer signed.
13701 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
13702 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
13703 x_dnd_atoms_size and x_dnd_atoms_length.
13705 * doprnt.c: Prefer signed to unsigned when either works.
13707 * doprnt.c (doprnt):
13709 * xdisp.c (vmessage):
13710 Use ptrdiff_t, not size_t, when using or implementing doprnt,
13711 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
13712 prefer signed arithmetic to avoid comparison confusion.
13713 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
13714 but is a bit tricky.
13716 Assume freestanding C89 headers, string.h, stdlib.h.
13717 * data.c, doprnt.c, floatfns.c, print.c:
13718 Include float.h unconditionally.
13719 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
13720 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
13721 * regex.c: Likewise for stddef.h, string.h.
13722 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
13723 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
13724 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
13725 (STDC_HEADERS): Remove obsolete defines.
13726 * sysdep.c: Include limits.h unconditionally.
13728 Assume support for memcmp, memcpy, memmove, memset.
13729 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
13730 * regex.c (memcmp, memcpy):
13731 Remove; we assume C89 now.
13733 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
13734 (__malloc_safe_bcopy): Remove; no longer needed.
13736 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
13737 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
13738 well either way, and we prefer signed to unsigned.
13740 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
13742 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
13743 closes the connection while we're reading (bug#9182).
13745 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
13747 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
13748 are specified (Bug#9168).
13750 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
13752 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
13753 Found by GCC static checking and --with-wide-int on a 32-bit host.
13755 2011-07-25 Eli Zaretskii <eliz@gnu.org>
13757 * xdisp.c (compute_display_string_pos): Fix logic of caching
13758 previous display string position. Initialize cached_prev_pos to
13759 -1. Fixes slow-down at the beginning of a buffer.
13761 2011-07-24 Eli Zaretskii <eliz@gnu.org>
13763 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
13764 for attrs[LFACE_FONTSET_INDEX].
13766 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
13768 * xml.c (parse_region): Remove unused local
13769 that was recently introduced.
13771 2011-07-23 Eli Zaretskii <eliz@gnu.org>
13773 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
13774 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
13776 * xdisp.c (move_it_in_display_line_to): Record the best matching
13777 position for TO_CHARPOS while scanning the line, and restore it on
13778 exit if none of the characters scanned was an exact match.
13779 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
13780 when exact match is impossible due to invisible text, and the
13781 lines are truncated.
13783 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
13785 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
13788 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13790 Fix a significant slow-down of cursor motion with C-n, C-p,
13791 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
13792 auto-repeat under bidi redisplay in fontified buffers.
13793 * xdisp.c (compute_stop_pos_backwards): New function.
13794 (next_element_from_buffer): Call compute_stop_pos_backwards to
13795 find a suitable prev_stop when we find ourselves before
13797 (reseat): Don't look for prev_stop, as that could mean a very long
13799 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
13800 <cached_disp_overlay_modiff>: Cache for last found display string
13802 (compute_display_string_pos): Return the cached position if asked
13803 about the same buffer in the same area of character positions, and
13804 the buffer wasn't changed since the time the display string
13805 position was cached.
13807 2011-07-22 Eli Zaretskii <eliz@gnu.org>
13809 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
13810 is an integer, which is important for empty lines. (Bug#9149)
13812 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
13814 * frame.c (Fmodify_frame_parameters): In tty case, update the
13815 default face if necessary (Bug#4238).
13817 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
13819 * editfns.c (Fstring_to_char): No need to explain what a character
13820 is in the docstring (Bug#6576).
13822 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13824 * xml.c (parse_region): Make sure we always return a tree.
13826 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
13828 * xml.c (parse_region): If a document contains only comments,
13831 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
13833 * xml.c (make_dom): Return comments, too.
13835 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
13838 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
13839 and the surrounding thread.
13840 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
13841 rather than fgets, and retry after EINTR. Otherwise, 'emacs
13842 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
13844 * s/openbsd.h (BROKEN_SIGIO): Define.
13845 * unexelf.c (unexec) [__OpenBSD__]:
13846 Don't update the .mdebug section of the Alpha COFF symbol table.
13848 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
13850 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
13853 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
13855 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
13856 This fixes some race conditions on the permissions of any newly
13859 * alloc.c (valid_pointer_p): Use pipe, not open.
13860 This fixes some permissions issues when debugging.
13862 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
13863 If fchown fails to set both uid and gid, try to set just gid,
13864 as that is sometimes allowed. Adjust the file's mode to eliminate
13865 setuid or setgid bits that are inappropriate if fchown fails.
13867 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
13869 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
13870 to compare Lisp_Objects.
13871 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
13872 global_gnutls_log_level, don't mistake it for a Lisp_Object.
13873 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
13875 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
13877 * lread.c (read_integer): Unread even EOF character.
13878 (read1): Likewise. Properly record start position of symbol.
13880 * lread.c (read1): Read `#:' as empty uninterned symbol if no
13881 symbol character follows.
13883 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
13885 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
13886 This works around a problem with the previous change to Fcopy_file.
13887 Recent glibc declares fchown with __attribute__((warn_unused_result)),
13888 and without this change, GCC might complain about discarding
13889 fchown's return value.
13891 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
13893 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
13895 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
13897 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
13899 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
13901 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
13902 it's used from the C level.
13904 * process.c: Use the same condition for POLL_FOR_INPUT in both
13905 keyboard.c and process.c (bug#1858).
13907 2011-07-09 Lawrence Mitchell <wence@gmx.li>
13909 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
13910 (Fgnutls_boot): Use it.
13912 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
13914 * doc.c (Fsubstitute_command_keys): Revert last change.
13916 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
13918 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
13919 quotes the next character, and doesn't affect other longer
13920 sequences (bug#8935).
13922 * lread.c (syms_of_lread): Clarify that is isn't only

13934 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
13935 (elsz): Now a signed constant, not a size_t var. We prefer signed
13936 types to unsigned, to avoid integer comparison confusion. Without

13987 the iterator is before prev_stop.
13988 (init_iterator): Initialize bidi_p from the default value of

14469 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

14506 Random fixes. E.g., (random) never returned negative values.
14507 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
14508 subseconds part to the entropy, as that's a bit more random.
14509 Prefer signed to unsigned, since the signedness doesn't matter and
14510 in general we prefer signed. When given a limit, use a
14511 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
14512 latter isn't right if USE_2_TAGS_FOR_INTS.
14513 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
14514 not 0..VALMASK. Don't discard "excess" bits that random () returns.

14526 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
14527 This is more efficient than Ffile_directory_p and avoids a minor race.

14531 * buffer.c (Foverlay_put): Say what the return value is
14534 * fileio.c (barf_or_query_if_file_exists): Check first if the file

14538 error be more correct.
14540 * fns.c (Frequire): Remove the mention of the .gz files, since

14554 Qgnutls_bootprop_verify_error (which is no longer used).
14556 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
14557 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
14558 Also (re)move comments that are misplaced or no longer relevant.

14587 * lread.c (syms_of_lread): Mention single symbols defined by

14659 * eval.c (struct backtrace): Simplify and port the data structure.
14660 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
14661 signed bit field, as this assumption is not portable and it makes
14662 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
14663 "char debug_on_exit : 1" as this is not portable either; instead,
14664 use the portable "unsigned int debug_on_exit : 1". Remove unused
14665 member evalargs. Remove obsolete comments about cc bombing out.
14667 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

14825 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
14827 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
14829 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
14831 Integer and buffer overflow fixes (Bug#8873).
14833 * print.c (printchar, strout): Check for string overflow.
14834 (PRINTPREPARE, printchar, strout):
14835 Don't set size unless allocation succeeds.
14837 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
14838 for sizes. Check for string overflow more accurately.
14839 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
14841 * macros.c: Integer and buffer overflow fixes.
14842 * keyboard.h (struct keyboard.kbd_macro_bufsize):
14843 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
14844 Use ptrdiff_t, not int, for sizes.
14845 Don't increment bufsize until after realloc succeeds.
14846 Check for size-calculation overflow.
14847 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
14849 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
14851 * lread.c: Integer overflow fixes.
14852 (read_integer): Radix is now EMACS_INT, not int,
14853 to improve quality of diagnostics for out-of-range radices.
14854 Calculate buffer size correctly for out-of-range radices.
14855 (read1): Check for integer overflow in radices, and in
14856 read-circle numbers.
14857 (read_escape): Avoid int overflow.
14858 (Fload, openp, read_buffer_size, read1)
14859 (substitute_object_recurse, read_vector, read_list, map_obarray):
14860 Use ptrdiff_t, not int, for sizes.
14861 (read1): Use EMACS_INT, not int, for sizes.
14862 Check for size overflow.
14864 * image.c (cache_image): Check for size arithmetic overflow.
14866 * lread.c: Integer overflow issues.
14867 (saved_doc_string_size, saved_doc_string_length)
14868 (prev_saved_doc_string_size, prev_saved_doc_string_length):
14869 Now ptrdiff_t, not int.

14871 out-of-range doc string lengths.
14872 (read_list): Don't assume file position fits in int.
14873 (read_escape): Check for hex character overflow.
14875 2011-06-22 Leo Liu <sdl.web@gmail.com>
14877 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
14878 Move to minibuffer.el.
14880 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14882 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
14883 The following patches are for when GLYPH_DEBUG && !XASSERT.
14884 * dispextern.h (trace_redisplay_p, dump_glyph_string):
14885 * dispnew.c (flush_stdout):
14886 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
14887 Mark as externally visible.
14888 * dispnew.c (check_window_matrix_pointers): Now static.
14889 * dispnew.c (window_to_frame_vpos):
14890 * xfns.c (unwind_create_frame):
14891 * xterm.c (x_check_font): Remove unused local.
14892 * scroll.c (CHECK_BOUNDS):
14893 * xfaces.c (cache_fache): Rename local to avoid shadowing.
14894 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
14895 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
14896 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
14897 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
14899 (debug_method_add): Use va_list and vsprintf rather than relying
14900 on undefined behavior with wrong number of arguments.
14901 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
14902 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
14903 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
14904 since we're not interested in debugging glyphs with old libraries.
14905 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
14906 GCC 4.6.0's static checking.
14908 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
14910 Integer overflow and signedness fixes (Bug#8873).
14911 A few related buffer overrun fixes, too.

14918 (x_create_bitmap_from_data, x_create_bitmap_from_file)
14919 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
14920 (x_create_bitmap_from_xpm_data):
14921 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
14922 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
14924 * xfaces.c (load_pixmap):
14925 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
14926 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
14927 (.bitmaps_last, struct x_output.icon_bitmap):
14928 Use ptrdiff_t, not int, for bitmap indexes.
14929 (x_allocate_bitmap_record): Check for size overflow.
14930 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
14932 Use ptrdiff_t, not int, for overlay counts.
14933 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
14934 * editfns.c (overlays_around, get_pos_property):
14935 * textprop.c (get_char_property_and_overlay):
14936 * xdisp.c (next_overlay_change, note_mouse_highlight):
14937 * xfaces.c (face_at_buffer_position):
14938 * buffer.c (OVERLAY_COUNT_MAX): New macro.
14939 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
14940 (Fnext_overlay_change, Fprevious_overlay_change)
14941 (mouse_face_overlay_overlaps, Foverlays_in):
14942 Use ptrdiff_t, not int, for sizes.
14943 (overlays_at, overlays_in): Check for size-calculation overflow.
14945 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
14947 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
14948 (x_session_initialize): Do not assume string length fits in int.
14950 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
14951 This is unlikely, but can occur if DPI is outlandish.
14953 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
14954 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
14956 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
14957 * xrdb.c (magic_file_p, search_magic_path):
14958 Omit last arg SUFFIX; it was always 0. All callers changed.
14959 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
14961 * xfont.c (xfont_match): Avoid need for strlen.
14963 * xfns.c: Don't assume strlen fits in int.
14964 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
14966 * xdisp.c (message_log_check_duplicate): Return intmax_t,
14967 not unsigned long, as we prefer signed integers. All callers changed.
14968 Detect integer overflow in repeat count.
14969 (message_dolog): Don't assume print length fits in 39 bytes.
14970 (display_mode_element): Don't assume strlen fits in int.
14972 * termcap.c: Don't assume sizes fit in int and never overflow.
14973 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
14974 (gobble_line): Check for size-calculation overflow.
14976 * minibuf.c (Fread_buffer):
14977 * lread.c (intern, intern_c_string):
14978 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
14979 Don't assume string length fits in int.
14981 * keyboard.c (parse_tool_bar_item):
14982 * gtkutil.c (style_changed_cb): Avoid need for strlen.
14984 * font.c: Don't assume string length fits in int.
14985 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
14986 Use ptrdiff_t, not int.
14987 (font_intern_prop): Don't assume string length fits in int.
14988 Don't assume integer property fits in fixnum.
14989 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
14991 * filelock.c: Fix some buffer overrun and integer overflow issues.
14992 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
14993 Reformulate so as not to need the command string.
14994 Invoke gzip -cd rather than gunzip, as it's more portable.
14995 (lock_info_type, lock_file_1, lock_file):
14996 Don't assume pid_t and time_t fit in unsigned long.
14997 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
14998 (current_lock_owner): Prefer signed type for sizes.
14999 Use memcpy, not strncpy, where memcpy is what is really wanted.
15000 Don't assume (via atoi) that time_t and pid_t fit in int.
15001 Check for time_t and/or pid_t out of range, e.g., via a network share.
15002 Don't alloca where an auto var works fine.
15004 * fileio.c: Fix some integer overflow issues.
15005 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
15006 Don't assume string length fits in int.
15007 (directory_file_name): Don't assume string length fits in long.
15008 (make_temp_name): Don't assume pid fits in int, or that its print
15009 length is less than 20.
15011 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
15013 * coding.c (make_subsidiaries): Don't assume string length fits in int.
15015 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
15017 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
15018 We prefer signed integers, even for size calculations.
15020 * emacs.c: Don't assume string length fits in 'int'.
15021 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
15022 (main): Don't invoke strlen when not needed.
15024 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
15025 (XD_DEBUG_MESSAGE): Don't waste a byte.
15027 * callproc.c (getenv_internal_1, getenv_internal)
15028 (Fgetenv_internal):
15029 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
15031 * lread.c (invalid_syntax): Omit length argument.
15032 All uses changed. This doesn't fix a bug, but it simplifies the
15033 code away from its former Hollerith-constant appearance, and it's
15034 one less 'int' to worry about when looking at integer-overflow issues.
15035 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
15037 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
15038 This didn't break anything, but it didn't help either.
15039 It's confusing to put a bogus integer in a place where the actual
15040 value does not matter.
15041 (LIST_END_P): Remove unused macro and its bogus comment.
15042 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
15044 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
15045 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
15047 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
15048 We prefer signed types, and the value cannot exceed the EMACS_INT
15049 range anyway (because otherwise the length would not be representable).
15050 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
15051 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
15052 This avoids a GCC warning when WIDE_EMACS_INT.
15054 * indent.c (sane_tab_width): New function.
15055 (current_column, scan_for_column, Findent_to, position_indentation)
15056 (compute_motion): Use it. This is just for clarity.
15057 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
15059 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
15061 * lisp.h (lint_assume): New macro.
15062 * composite.c (composition_gstring_put_cache):
15063 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
15065 * editfns.c, insdel.c:
15066 Omit unnecessary forward decls, to simplify future changes.
15068 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
15070 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
15072 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
15073 Use much-faster test for byte-length change.
15074 Don't assume string byte-length fits in 'int'.
15075 Check that character arg fits in 'int'.
15076 (mapcar1): Declare byte as byte, for clarity.
15078 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
15080 * fns.c (concat): Catch string overflow earlier.
15081 Do not rely on integer wraparound.
15083 * dispextern.h (struct it.overlay_strings_charpos)
15084 (struct it.selective): Now EMACS_INT, not int.
15085 * xdisp.c (forward_to_next_line_start)
15086 (back_to_previous_visible_line_start)
15087 (reseat_at_next_visible_line_start, next_element_from_buffer):
15088 Don't arbitrarily truncate the value of 'selective' to int.
15090 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
15092 * composite.c: Don't truncate sizes to 'int'.
15093 (composition_gstring_p, composition_reseat_it)
15094 (composition_adjust_point): Use EMACS_INT, not int.
15095 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
15096 not EMACS_UINT, for indexes.
15098 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
15100 * buffer.c: Include <verify.h>.
15101 (struct sortvec.priority, struct sortstr.priority):
15102 Now EMACS_INT, not int.
15103 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
15104 (struct sortstr.size, record_overlay_string)
15105 (struct sortstrlist.size, struct sortlist.used):
15106 Don't truncate size to int.
15107 (record_overlay_string): Check for size-calculation overflow.
15108 (init_buffer_once): Check at compile-time, not run-time.
15110 2011-06-22 Jim Meyering <meyering@redhat.com>
15112 Don't leak an XBM-image-sized buffer
15113 * image.c (xbm_load): Free the image buffer after using it.
15115 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
15118 * composite.c (find_automatic_composition): Omit needless 'return 0;'
15119 that Sun C diagnosed.
15120 * fns.c (secure_hash): Fix pointer signedness issue.
15121 * intervals.c (static_offset_intervals): New function.
15122 (offset_intervals): Use it.
15124 2011-06-21 Leo Liu <sdl.web@gmail.com>
15127 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
15130 * fns.c (secure_hash): Rename from crypto_hash_function and change
15131 the first arg to accept symbols.
15132 (Fsecure_hash): New primitive.
15133 (syms_of_fns): New symbols.
15135 2011-06-20 Deniz Dogan <deniz@dogan.se>
15137 * process.c (Fset_process_buffer): Clarify return value in
15140 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
15142 * dispnew.c (add_window_display_history): Use BVAR.
15144 * xdisp.c (debug_method_add): Use BVAR.
15145 (check_window_end, dump_glyph_matrix, dump_glyph)
15146 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
15148 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
15151 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
15152 check till after the cache is created in init_frame_faces.
15154 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
15156 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
15158 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
15160 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
15161 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
15162 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
15164 Improve buffer-overflow checking (Bug#8873).
15165 * fileio.c (Finsert_file_contents):
15166 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
15167 Remove the old (too-loose) buffer overflow checks.
15168 They weren't needed, since make_gap checks for buffer overflow.
15169 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
15170 The old code merely checked for Emacs fixnum overflow, and relied
15171 on undefined (wraparound) behavior. The new code avoids undefined
15172 behavior, and also checks for ptrdiff_t and/or size_t overflow.
15174 * editfns.c (Finsert_char): Don't dump core with very negative counts.
15175 Tune. Don't use wider integers than needed. Don't use alloca.
15176 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
15178 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
15180 * insdel.c, lisp.h (buffer_overflow): New function.
15181 (insert_from_buffer_1, replace_range, replace_range_2):
15182 * insdel.c (make_gap_larger):
15183 * editfns.c (Finsert_char):
15184 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
15186 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
15188 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
15190 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
15192 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
15193 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
15195 * fileio.c: Don't assume EMACS_INT fits in off_t.
15196 (emacs_lseek): New static function.
15197 (Finsert_file_contents, Fwrite_region): Use it.
15198 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
15200 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
15202 * fns.c: Don't overflow int when computing a list length.
15203 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
15204 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
15205 truncation on 64-bit hosts. Check for QUIT every
15206 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
15207 faster and is responsive enough.
15208 (Flength): Report an error instead of overflowing an integer.
15209 (Fsafe_length): Return a float if the value is not representable
15210 as a fixnum. This shouldn't happen except in contrived situations.
15211 (Fnthcdr, Fsort): Don't assume list length fits in int.
15212 (Fcopy_sequence): Don't assume vector length fits in int.
15214 * alloc.c: Check that resized vectors' lengths fit in fixnums.
15215 (header_size, word_size): New constants.
15216 (allocate_vectorlike): Don't check size overflow here.
15217 (allocate_vector): Check it here instead, since this is the only
15218 caller of allocate_vectorlike that could cause overflow.
15219 Check that the new vector's length is representable as a fixnum.
15221 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
15222 The previous code was bogus. For example, next_almost_prime (32)
15223 returned 39, which is undesirable as it is a multiple of 3; and
15224 next_almost_prime (24) returned 25, which is a multiple of 5 so
15225 why was the code bothering to check for multiples of 7?
15227 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
15229 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
15231 Variadic C functions now count arguments with ptrdiff_t.
15232 This partly undoes my 2011-03-30 change, which replaced int with size_t.
15233 Back then I didn't know that the Emacs coding style prefers signed int.
15234 Also, in the meantime I found a few more instances where arguments
15235 were being counted with int, which may truncate counts on 64-bit
15236 machines, or EMACS_INT, which may be unnecessarily wide.
15237 * lisp.h (struct Lisp_Subr.function.aMANY)
15238 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
15239 Arg counts are now ptrdiff_t, not size_t.
15240 All variadic functions and their callers changed accordingly.
15241 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
15242 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
15243 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
15244 * callint.c (Fcall_interactively): Check arg count for overflow,
15245 to avoid potential buffer overrun. Use signed char, not 'int',
15246 for 'varies' array, so that we needn't bother to check its size
15247 calculation for overflow.
15248 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
15249 * eval.c (apply_lambda):
15250 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
15251 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
15252 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
15254 * callint.c (Fcall_interactively): Don't use index var as event count.
15256 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
15257 * mem-limits.h (SIZE): Remove; no longer used.
15259 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
15261 Remove unnecessary casts.
15262 * xterm.c (x_term_init):
15263 * xfns.c (x_set_border_pixel):
15264 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
15265 These aren't needed now that we assume ANSI C.
15267 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
15268 It's more likely to cause problems (due to unsigned overflow)
15271 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
15273 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
15275 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
15277 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
15279 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
15281 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
15283 GLYPH_CODE_FACE returns EMACS_INT, not int.
15284 * dispextern.h (merge_faces):
15285 * xfaces.c (merge_faces):
15286 * xdisp.c (get_next_display_element, next_element_from_display_vector):
15287 Don't assume EMACS_INT fits in int.
15289 * character.h (CHAR_VALID_P): Remove unused parameter.
15290 * fontset.c, lisp.h, xdisp.c: All uses changed.
15292 * editfns.c (Ftranslate_region_internal): Omit redundant test.
15294 * fns.c (concat): Minor tuning based on overflow analysis.
15295 This doesn't fix any bugs. Use int to hold character, instead
15296 of constantly refetching from Emacs object. Use XFASTINT, not
15297 XINT, for value known to be a character. Don't bother comparing
15298 a single byte to 0400, as it's always less.
15300 * floatfns.c (Fexpt):
15301 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
15303 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
15306 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
15308 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
15309 Without this fix, on a 64-bit host (aset S 0 4294967386) would
15310 incorrectly succeed when S was a string, because 4294967386 was
15311 truncated before it was used.
15313 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
15314 Otherwise, an out-of-range integer could cause undefined behavior
15317 * composite.c: Use int, not EMACS_INT, for characters.
15318 (fill_gstring_body, composition_compute_stop_pos): Use int, not
15319 EMACS_INT, for values that are known to be in character range.
15320 This doesn't fix any bugs but is the usual style inside Emacs and
15321 may generate better code on 32-bit machines.
15323 Make sure a 64-bit char is never passed to ENCODE_CHAR.
15324 This is for reasons similar to the recent CHAR_STRING fix.
15325 * charset.c (Fencode_char): Check that character arg is actually
15326 a character. Pass an int to ENCODE_CHAR.
15327 * charset.h (ENCODE_CHAR): Verify that the character argument is no
15328 wider than 'int', as a compile-time check to prevent future regressions
15331 * character.c (char_string): Remove unnecessary casts.
15333 Make sure a 64-bit char is never passed to CHAR_STRING.
15334 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
15335 by silently ignoring the top 32 bits, allowing some values
15336 that were far too large to be valid characters.
15337 * character.h: Include <verify.h>.
15338 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
15339 arguments are no wider than unsigned, as a compile-time check
15340 to prevent future regressions in this area.
15342 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
15343 (Fsubst_char_in_region):
15345 * xdisp.c (decode_mode_spec_coding):
15346 Adjust to CHAR_STRING's new requirement.
15347 * editfns.c (Finsert_char, Fsubst_char_in_region):
15348 * fns.c (concat): Check that character args are actually
15349 characters. Without this test, these functions did the wrong
15350 thing with wildly out-of-range values on 64-bit hosts.
15352 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
15353 These casts should not be needed on 32-bit hosts, either.
15354 * keyboard.c (read_char):
15355 * lread.c (Fload): Remove casts to unsigned.
15357 * lisp.h (UNSIGNED_CMP): New macro.
15358 This fixes comparison bugs on 64-bit hosts.
15359 (ASCII_CHAR_P): Use it.
15360 * casefiddle.c (casify_object):
15361 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
15362 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
15363 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
15364 * dispextern.h (FACE_FROM_ID):
15365 * keyboard.c (read_char): Use UNSIGNED_CMP.
15367 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
15368 not to EMACS_INT, to avoid GCC warning.
15370 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
15372 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
15373 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
15374 isn't needed on 32-bit machines.
15376 * buffer.c (Fgenerate_new_buffer_name):
15377 Use EMACS_INT for count, not int.
15378 (advance_to_char_boundary): Return EMACS_INT, not int.
15380 * data.c (Qcompiled_function): Now static.
15382 * window.c (window_body_lines): Now static.
15384 * image.c (gif_load): Rename local to avoid shadowing.
15386 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
15387 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
15388 * alloc.c (make_save_value): Integer argument is now of type
15389 ptrdiff_t, not int.
15390 (mark_object): Use ptrdiff_t, not int.
15391 * lisp.h (pD): New macro.
15392 * print.c (print_object): Use it.
15394 * alloc.c: Use EMACS_INT, not int, to count objects.
15395 (total_conses, total_markers, total_symbols, total_vector_size)
15396 (total_free_conses, total_free_markers, total_free_symbols)
15397 (total_free_floats, total_floats, total_free_intervals)
15398 (total_intervals, total_strings, total_free_strings):
15399 Now EMACS_INT, not int. All uses changed.
15400 (Fgarbage_collect): Compute overall total using a double, so that
15401 integer overflow is less likely to be a problem. Check for overflow
15402 when converting back to an integer.
15403 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
15404 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
15405 These were 'int' variables that could overflow on 64-bit hosts;
15406 they were never used, so remove them instead of repairing them.
15407 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
15408 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
15409 Previously, this ceilinged at INT_MAX, but that doesn't work on
15411 (allocate_pseudovector): Don't use EMACS_INT when int would do.
15413 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
15414 (allocate_vectorlike): Check for ptrdiff_t overflow.
15415 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
15416 when a (possibly-narrower) signed value would do just as well.
15417 We prefer using signed arithmetic, to avoid comparison confusion.
15419 * alloc.c: Catch some string size overflows that we were missing.
15420 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
15421 for convenience in STRING_BYTES_MAX.
15422 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
15423 The definition here is exact; the one in lisp.h was approximate.
15424 (allocate_string_data): Check for string overflow. This catches
15425 some instances we weren't catching before. Also, it catches
15426 size_t overflow on (unusual) hosts where SIZE_MAX <= min
15427 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
15428 and ptrdiff_t and EMACS_INT are both 64 bits.
15430 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
15431 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
15432 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
15434 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
15436 * alloc.c (Fmake_string): Check for out-of-range init.
15438 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
15440 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
15442 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
15444 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
15445 xg_get_default_scrollbar_width.
15447 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.

15455 and height if HAVE_GTK3 (Bug#8505).
15456 (scroll_bar_width_for_theme): New variable.
15457 (update_theme_scrollbar_width): New function.
15458 (xg_get_default_scrollbar_width): Move code to
15459 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
15460 (xg_initialize): Call update_theme_scrollbar_width.
15462 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
15464 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
15466 2011-06-12 Martin Rudalics <rudalics@gmx.at>
15468 * frame.c (make_frame): Call other_buffer_safely instead of
15471 * window.c (temp_output_buffer_show): Call display_buffer with
15472 second argument Vtemp_buffer_show_specifiers and reset latter
15473 immediately after the call.
15474 (Vtemp_buffer_show_specifiers): New variable.
15475 (auto_window_vscroll_p, next_screen_context_lines)
15476 (Vscroll_preserve_screen_position): Remove leading asterisks from

15499 wasn't returning anything.
15500 (compare_window_configurations): Remove unused locals.
15501 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
15502 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
15503 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers

15659 Remove static from declaration of Qdelete_window, it's
15660 temporarily needed by Fbury_buffer.
15661 (replace_window): Don't assign orig_top_line and

16021 were just reseat()'ed to a new position.
16023 * xdisp.c (set_cursor_from_row): Set start and stop points

16039 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
16040 value of a `display' property is a "replacing spec".
16041 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
16042 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

16072 * gnutls.c: Use Emacs's memory allocators.
16073 Without this change, the gnutls library would invoke malloc etc.
16074 directly, which causes problems on non-SYNC_INPUT hosts, and which
16075 runs afoul of improving memory_full behavior. (Bug#8761)
16076 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
16077 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
16078 xfree instead of the default malloc, realloc, free.
16079 (Fgnutls_boot): No need to check for memory allocation failure,
16080 since xmalloc does that for us.

16102 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
16103 for hashes and hash indexes, instead of 'unsigned' and 'int'.
16104 * alloc.c (allocate_vectorlike):
16105 Check for overflow in vector size calculations.
16106 * ccl.c (ccl_driver):
16107 Check for overflow when converting EMACS_INT to int.
16108 * fns.c, image.c: Remove unnecessary static decls that would otherwise
16109 need to be updated by these changes.
16110 * fns.c (make_hash_table, maybe_resize_hash_table):
16111 Check for integer overflow with large hash tables.
16112 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
16113 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
16114 (SXHASH_REDUCE): New macro.
16115 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
16116 Use it instead of discarding useful hash info with large hash values.
16117 (sxhash_float): New function.
16118 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
16119 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
16120 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
16121 Rewrite to use FIXNUM_BITS, as this simplifies things.
16122 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
16123 Adjust signatures to match updated version of code.
16124 (consing_since_gc): Now EMACS_INT, since a single hash table can
16125 use more than INT_MAX bytes.
16127 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
16129 Make it possible to build with GCC-4.6+ -O2 -flto.

16133 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
16135 * minibuf.c (get_minibuffer, read_minibuf_unwind):
16136 Call minibuffer-inactive-mode.
16138 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
16140 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
16141 Update dependencies.
16143 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16145 * data.c (init_data): Remove code for UTS, this system is not
16148 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16150 Don't force ./temacs to start in terminal mode.
16152 * frame.c (make_initial_frame): Initialize faces in all cases, not
16153 only when CANNOT_DUMP is defined.
16154 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
16156 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16158 * dispnew.c (add_window_display_history): Use const for the string
16159 pointer. Remove declaration, not needed.
16161 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16163 Use 'inline', not 'INLINE'.
16164 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
16165 * alloc.c, fontset.c (INLINE): Remove.
16166 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
16167 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
16168 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
16169 * gmalloc.c (register_heapinfo): Use inline unconditionally.
16170 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
16172 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
16174 Make it possible to run ./temacs.
16176 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
16177 syms_of_callproc does the same thing. Remove test for
16178 "initialized", do it in the caller.
16179 * emacs.c (main): Avoid calling set_initial_environment when dumping.
16181 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
16183 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
16184 (read_minibuf): Use get_minibuffer.
16185 (syms_of_minibuf): Use DEFSYM.
16186 (Qmetadata): New var.
16187 * data.c (Qbuffer): Don't make it static.
16188 (syms_of_data): Use DEFSYM.
16190 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
16192 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
16193 (CCL_CODE_MIN): New macro.
16195 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
16197 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
16199 * eval.c (Qdebug): Now static.
16200 * lisp.h (Qdebug): Remove decl. This reverts a part of the
16201 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
16202 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
16204 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16206 * image.c: Various fixes to ImageMagick code comments.
16207 (Fimagemagick_types): Doc fix.
16209 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
16211 Minor fixes prompted by GCC 4.6.0 warnings.
16213 * xselect.c (converted_selections, conversion_fail_tag): Now static.
16215 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
16216 (x_clipboard_manager_save_all): Move extern decl to ...
16217 * xterm.h: ... here, so that it can be checked for consistency.
16219 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
16221 * xselect.c (x_clipboard_manager_save_frame)
16222 (x_clipboard_manager_save_all): New functions.
16223 (Fx_clipboard_manager_save): Lisp function deleted.
16225 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
16226 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
16228 * xterm.h: Update prototype.
16230 2011-05-28 William Xu <william.xwl@gmail.com>
16232 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
16233 exiting (Bug#8239).
16235 2011-05-28 Jim Meyering <meyering@redhat.com>
16237 Avoid a sign-extension bug in crypto_hash_function.
16238 * fns.c (to_uchar): Define.
16239 (crypto_hash_function): Use it to convert some newly-signed
16240 variables to unsigned, to avoid sign-extension bugs. For example,
16241 without this change, (md5 "truc") would evaluate to
16242 45723a2aff78ff4fff7fff1114760e62 rather than the expected
16243 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
16244 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
16246 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16248 Integer overflow fixes.
16250 * dbusbind.c: Serial number integer overflow fixes.
16251 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
16252 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
16253 to hold a serial number that is too large for a fixnum.
16254 (Fdbus_method_return_internal, Fdbus_method_error_internal):
16255 Check for serial numbers out of range. Decode any serial number
16256 that was so large that it became a float. (Bug#8722)
16258 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
16259 (Fdbus_call_method, Fdbus_call_method_asynchronously):
16260 Use XFASTINT rather than XUINT when numbers are nonnegative.
16261 (xd_append_arg, Fdbus_method_return_internal):
16262 (Fdbus_method_error_internal): Likewise. Also, for unsigned
16263 arguments, check that Lisp number is nonnegative, rather than
16264 silently wrapping negative numbers around. (Bug#8722)
16265 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
16268 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
16270 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
16272 ccl: Add integer overflow checks.
16273 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
16274 (IN_INT_RANGE): New macros.
16275 (ccl_driver): Use them to check for integer overflow when
16276 decoding a CCL program. Many of the new checks are whether XINT (x)
16277 fits in int; it doesn't always, on 64-bit hosts. The new version
16278 doesn't catch all possible integer overflows, but it's an
16279 improvement. (Bug#8719)
16281 * alloc.c (make_event_array): Use XINT, not XUINT.
16282 There's no need for unsigned here.
16284 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
16285 This follows up to the 2011-05-06 change that substituted uintptr_t
16286 for EMACS_INT. This case wasn't caught back then.
16288 Rework Fformat to avoid integer overflow issues.
16289 * editfns.c: Include <float.h> unconditionally, as it's everywhere
16290 now (part of C89). Include <verify.h>.
16291 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
16292 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
16293 (Fformat): Avoid the prepass trying to compute sizes; it was only
16294 approximate and thus did not catch overflow reliably. Instead, walk
16295 through the format just once, formatting and computing sizes as we go,
16296 checking for integer overflow at every step, and allocating a larger
16297 buffer as needed. Keep track separately whether the format is
16298 multibyte. Keep only the most-recently calculated precision, rather
16299 than them all. Record whether each argument has been converted to
16300 string. Use EMACS_INT, not int, for byte and char and arg counts.
16301 Support field widths and precisions larger than INT_MAX. Avoid
16302 sprintf's undefined behavior with conversion specifications such as %#d
16303 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
16304 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
16305 formatting out-of-range floating point numbers with int
16306 formats. (Bug#8668)
16308 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
16310 * data.c: Avoid integer truncation in expressions involving floats.
16311 * data.c: Include <intprops.h>.
16312 (arith_driver): When there's an integer overflow in an expression
16313 involving floating point, convert the integers to floating point
16314 so that the resulting value does not suffer from catastrophic
16315 integer truncation. For example, on a 64-bit host (* 4
16316 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
16317 Do not rely on undefined behavior after integer overflow.
16319 merge count_size_as_multibyte, parse_str_to_multibyte
16320 * character.c, character.h (count_size_as_multibyte):
16321 Rename from parse_str_to_multibyte; all uses changed.
16322 Check for integer overflow.
16323 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
16324 since it's now a duplicate of the other. This is more of
16325 a character than a buffer op, so better that it's in character.c.
16326 * fns.c, print.c: Adjust to above changes.
16328 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
16330 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
16332 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
16334 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16335 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
16336 (x_clipboard_manager_save): Now static.
16337 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
16339 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
16340 (crypto_hash_function): Now static.
16341 Fix pointer signedness problems. Avoid unnecessary initializations.
16343 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
16345 * termhooks.h (Vselection_alist): Make it terminal-local.
16347 * terminal.c (create_terminal): Initialize it.
16349 * xselect.c: Support for clipboard managers.
16350 (Vselection_alist): Move to termhooks.h as terminal-local var.
16351 (LOCAL_SELECTION): New macro.
16352 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
16353 (symbol_to_x_atom): Remove gratuitous arg.
16354 (x_handle_selection_request, lisp_data_to_selection_data)
16355 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
16356 (x_own_selection, x_get_local_selection, x_convert_selection):
16357 New arg, specifying work frame. Use terminal-local Vselection_alist.
16358 (some_frame_on_display): Delete unused function.
16359 (Fx_own_selection_internal, Fx_get_selection_internal)
16360 (Fx_disown_selection_internal, Fx_selection_owner_p)
16361 (Fx_selection_exists_p): New optional frame arg.
16362 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
16363 (x_handle_selection_clear): Don't treat other terminals with the
16364 same keyboard specially. Use the terminal-local Vselection_alist.
16365 (x_clear_frame_selections): Use Frun_hook_with_args.
16367 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
16369 * xterm.h: Add support for those atoms.
16371 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
16373 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
16374 (converted_selections, conversion_fail_tag): New global variables.
16375 (x_selection_request_lisp_error): Free the above.
16376 (x_get_local_selection): Remove unnecessary code.
16377 (x_reply_selection_request): Args changed; handle arbitrary array
16378 of converted selections stored in converted_selections.
16379 Separate the XChangeProperty and SelectionNotify steps.
16380 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
16381 (x_convert_selection): New function.
16382 (x_handle_selection_event): Simplify.
16383 (x_get_foreign_selection): Don't ignore incoming requests while
16384 waiting for an answer; this will fail when we implement
16385 SAVE_TARGETS, and seems unnecessary anyway.
16386 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
16387 (Vx_sent_selection_functions): Doc fix.
16389 2011-05-26 Leo Liu <sdl.web@gmail.com>
16391 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
16393 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16395 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
16397 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
16398 for fringe update if it has periodic bitmap.
16399 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
16400 and fringe_bitmap_periodic_p.
16402 * fringe.c (get_fringe_bitmap_data): New function.
16403 (draw_fringe_bitmap_1, update_window_fringes): Use it.
16404 (update_window_fringes): Record periodicity of fringe bitmap in glyph
16405 row. Mark glyph row for fringe update if periodicity changed.
16407 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
16408 for fringe update unless it has periodic bitmap.
16410 2011-05-25 Kenichi Handa <handa@m17n.org>
16412 * xdisp.c (get_next_display_element): Set correct it->face_id for
16413 a static composition.
16415 2011-05-24 Leo Liu <sdl.web@gmail.com>
16418 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
16420 * fns.c (crypto_hash_function, Fsha1): New function.
16421 (Fmd5): Use crypto_hash_function.
16422 (syms_of_fns): Add Ssha1.
16424 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16426 * gnutls.c: Remove unused macros.
16427 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
16428 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
16429 Remove macros that are defined and never used.
16430 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
16432 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
16434 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
16435 (Fx_get_selection_internal): Minor cleanup.
16436 (Fx_own_selection_internal): Rename arguments for consistency with
16439 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
16441 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
16443 2011-05-22 Chong Yidong <cyd@stupidchicken.com>

16454 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
16455 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
16456 and add some more files.
16458 2011-05-20 Eli Zaretskii <eliz@gnu.org>
16460 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
16461 report_file_error introduced by the change from 2011-05-07.
16463 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
16465 * systime.h (Time): Define only if emacs is defined.
16466 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
16467 where the include path doesn't have X11/X.h by default. See
16468 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
16470 2011-05-20 Kenichi Handa <handa@m17n.org>
16472 * composite.c (find_automatic_composition): Fix previous change.
16474 2011-05-20 Glenn Morris <rgm@gnu.org>
16476 * lisp.mk: New file, split from Makefile.in.
16477 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
16478 (shortlisp): Remove.
16479 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
16481 2011-05-19 Glenn Morris <rgm@gnu.org>
16483 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
16484 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
16485 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
16486 (lisp): Set the order to that of loadup.el.
16487 (shortlisp): Make it a copy of $lisp.
16488 (SOME_MACHINE_LISP): Remove.
16489 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
16490 Use just $shortlisp, not $SOME_MACHINE_LISP too.
16492 2011-05-18 Kenichi Handa <handa@m17n.org>
16494 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
16495 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
16496 (find_automatic_composition): Mostly rewrite for efficiency.
16498 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
16500 * makefile.w32-in: Update dependencies.
16502 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
16504 * menu.c: Include limits.h (fixes the MS-Windows build broken by
16505 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
16507 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
16509 Fix some integer overflow issues, such as string length overflow.
16511 * insdel.c (count_size_as_multibyte): Check for string overflow.
16513 * character.c (lisp_string_width): Check for string overflow.
16514 Use EMACS_INT, not int, for string indexes and lengths; in
16515 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
16516 the resulting string length overflows an EMACS_INT; instead,
16517 report a string overflow if no precision given. When checking for
16518 precision exhaustion, use a check that cannot possibly have
16519 integer overflow. (Bug#8675)
16520 * character.h (lisp_string_width): Adjust to new signature.
16522 * alloc.c (string_overflow): New function.
16523 (Fmake_string): Use it. This doesn't change behavior, but saves
16524 a few bytes and will simplify future changes.
16525 * character.c (string_escape_byte8): Likewise.
16526 * lisp.h (string_overflow): New decl.
16528 Fixups, following up to the user-interface timestamp change.
16529 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
16530 for UI timestamps, instead of unsigned long.
16531 * msdos.c (mouse_get_pos): Likewise.
16532 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
16533 * w32gui.h (Time): Define by including "systime.h" rather than by
16534 declaring it ourselves. (Bug#8664)
16536 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
16537 * image.c (clear_image_cache): Likewise.
16539 * term.c (term_mouse_position): Don't assume time_t wraparound.
16541 Be more systematic about user-interface timestamps.
16542 Before, the code sometimes used 'Time', sometimes 'unsigned long',
16543 and sometimes 'EMACS_UINT', to represent these timestamps.
16544 This change causes it to use 'Time' uniformly, as that's what X uses.
16545 This makes the code easier to follow, and makes it easier to catch
16546 integer overflow bugs such as Bug#8664.
16547 * frame.c (Fmouse_position, Fmouse_pixel_position):
16548 Use Time, not unsigned long, for user-interface timestamps.
16549 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
16550 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
16551 * keyboard.h (last_event_timestamp): Likewise.
16552 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
16553 * menu.h (xmenu_show): Likewise.
16554 * term.c (term_mouse_position): Likewise.
16555 * termhooks.h (struct input_event.timestamp): Likewise.
16556 (struct terminal.mouse_position_hook): Likewise.
16557 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
16558 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
16559 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
16560 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
16561 what it was before.
16562 * menu.h, termhooks.h: Include "systime.h", for Time.
16564 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
16565 Don't assume that the difference between two unsigned long values
16566 can fit into an integer. At this point, we know button_down_time
16567 <= event->timestamp, so the difference must be nonnegative, so
16568 there's no need to cast the result if double-click-time is
16569 nonnegative, as it should be; check that it's nonnegative, just in
16570 case. This bug is triggered when events are more than 2**31 ms
16571 apart (about 25 days). (Bug#8664)
16573 * xselect.c (last_event_timestamp): Remove duplicate decl.
16574 (x_own_selection): Remove needless cast to unsigned long.
16576 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
16577 that always fit in int. Use a sentinel instead of a counter, to
16578 avoid a temp and to allay GCC's concerns about possible int overflow.
16579 * frame.h (struct frame): Use int for menu_bar_items_used
16580 instead of EMACS_INT, since it always fits in int.
16582 * menu.c (grow_menu_items): Check for int overflow.
16584 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
16586 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
16587 Before, the code was not consistent. These values cannot exceed
16588 2**31 - 1 so there's no need to make them unsigned.
16589 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
16590 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
16591 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
16593 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
16595 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
16596 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
16597 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
16598 presumably because the widths might not match.
16600 * window.c (size_window): Avoid needless test at loop start.
16602 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
16604 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
16606 2011-05-12 Drew Adams <drew.adams@oracle.com>
16608 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
16610 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16612 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
16613 `width' to `bar_area_x' and `bar_area_width', respectively.
16614 (x_scroll_run): Take account of fringe background extension.
16616 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
16617 Rename local vars `left' and `width' to `bar_area_x' and
16618 `bar_area_width', respectively.
16619 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
16620 background extension.
16622 2011-05-10 Jim Meyering <meyering@redhat.com>
16624 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
16626 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
16628 * image.c (Finit_image_library): Return t for built-in image types,
16629 like pbm and xbm. (Bug#8640)
16631 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
16633 * w32menu.c (set_frame_menubar): Fix submenu allocation.
16635 2011-05-07 Eli Zaretskii <eliz@gnu.org>
16637 * w32console.c (Fset_screen_color): Doc fix.
16638 (Fget_screen_color): New function.
16639 (syms_of_ntterm): Defsubr it.
16641 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
16642 unlink the temporary file if Fcall_process didn't create it in the
16644 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
16645 child process will be redirected to a file specified with `:file'.
16646 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
16647 cue to call_process_cleanup not to close that handle.
16649 2011-05-07 Ben Key <bkey76@gmail.com>
16651 * makefile.w32-in: The bootstrap-temacs rule now makes use of
16652 one of two shell specific rules, either bootstrap-temacs-CMD or
16653 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
16654 to the previous implementation of the bootstrap-temacs rule.
16655 The bootstrap-temacs-CMD rule is similar to the previous
16656 implementation of the bootstrap-temacs rule except that it
16657 makes use of the ESC_CFLAGS variable instead of the CFLAGS
16660 These changes, along with some changes to nt/configure.bat,
16661 nt/gmake.defs, and nt/nmake.defs, are required to extend my
16662 earlier fix to add support for --cflags and --ldflags options
16663 that include quotes so that it works whether make uses cmd or
16666 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
16668 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
16669 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
16671 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
16672 a string. Handle both cases.
16673 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
16674 (Fdbus_register_method): Use Qinvalid_function.
16676 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16678 * makefile.w32-in: Update dependencies.
16679 (LISP_H): Add inttypes.h and stdin.h.
16680 (PROCESS_H): Add unistd.h.
16682 2011-05-06 Eli Zaretskii <eliz@gnu.org>
16684 * lread.c: Include limits.h (fixes the MS-Windows build broken by
16685 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
16687 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
16689 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
16691 * term.c (vfatal): Remove stray call to va_end.
16692 It's not needed and the C Standard doesn't allow it here anyway.
16694 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
16695 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
16697 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
16700 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
16702 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16704 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
16706 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
16708 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
16710 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
16711 * charset.c (Fdefine_charset_internal): Don't initialize
16712 charset.code_space[15]. The value was garbage, on hosts with
16713 32-bit int (Bug#8600).
16715 * lread.c (read_integer): Be more consistent with string-to-number.
16716 Use string_to_number to do the actual conversion; this avoids
16717 rounding errors and fixes some other screwups. Without this fix,
16718 for example, #x1fffffffffffffff was misread as -2305843009213693952.
16719 (digit_to_number): Move earlier, for benefit of read_integer.
16720 Return -1 if the digit is out of range for the base, -2 if it is
16721 not a digit in any supported base. (Bug#8602)
16723 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
16725 * dispnew.c (scrolling_window): Return 1 if we scrolled,
16726 to match comment at start of function. This also removes a
16727 GCC warning about overflow in a 32+64-bit port.
16729 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
16731 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
16732 Reported by Stefan Monnier in
16733 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
16734 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16735 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
16737 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
16738 (EMACS_UINTPTR): Likewise, with uintptr_t.
16740 * lisp.h: Prefer 64-bit EMACS_INT if available.
16741 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
16742 on 32-bit hosts that have 64-bit int, so that they can access
16744 However, temporarily disable this change unless the temporary
16745 symbol WIDE_EMACS_INT is defined.
16747 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
16749 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
16750 This removes an assumption that EMACS_INT and long are the same
16751 width as pointers. The assumption is true for Emacs porting targets
16752 now, but we want to make other targets possible.
16753 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
16754 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
16755 In the rest of the code, change types of integers that hold casted
16756 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
16757 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
16758 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
16759 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
16760 No need to cast type when ORing.
16761 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
16762 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
16763 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
16764 assume EMACS_INT is the same width as char *.
16765 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
16766 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
16767 Remove no-longer-needed casts.
16768 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
16769 (xg_tool_bar_help_callback, xg_make_tool_item):
16770 Use EMACS_INTPTR to hold an integer
16771 that will be cast to void *; this can avoid a GCC warning
16772 if EMACS_INT is not the same width as void *.
16773 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
16774 * xdisp.c (display_echo_area_1, resize_mini_window_1):
16775 (current_message_1, set_message_1):
16776 Use a local to convert to proper width without a cast.
16777 * xmenu.c (dialog_selection_callback): Likewise.
16779 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
16780 Also, don't assume VALBITS / RAND_BITS is less than 5,
16781 and don't rely on undefined behavior when shifting a 1 left into
16783 * lisp.h (get_random): Change signature to match.
16785 * lread.c (hash_string): Use size_t, not int, for hash computation.
16786 Normally we prefer signed values; but hashing is special, because
16787 it's better to use unsigned division on hash table sizes so that
16788 the remainder is nonnegative. Also, size_t is the natural width
16789 for hashing into memory. The previous code used 'int', which doesn't
16790 retain enough info to hash well into very large tables.
16791 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
16793 * dbusbind.c: Don't possibly lose pointer info when converting.
16794 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
16795 Use XPNTR rather than XHASH, so that the high-order bits of
16796 the pointer aren't lost when converting through void *.
16798 * eval.c (Fautoload): Don't double-shift a pointer.
16800 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
16802 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
16804 * gnutls.c (DEF_GNUTLS_FN):
16805 * image.c (DEF_IMGLIB_FN): Make function pointers static.
16807 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
16809 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
16812 2011-05-05 Eli Zaretskii <eliz@gnu.org>
16814 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
16815 New version that can reserve upto 2GB of heap space.
16817 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
16819 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
16821 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
16823 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
16824 `gnutls_certificate_set_x509_key_file'.
16826 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
16828 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
16829 Update dependencies.
16831 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16833 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
16834 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
16835 Remove unused parameter `fildes'.
16836 * process.c (read_process_output, send_process): Don't pass it.
16838 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16840 Fix previous change: the library cache is defined in w32.c.
16841 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
16842 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
16844 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
16846 Implement dynamic loading of GnuTLS on Windows.
16848 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
16849 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
16850 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16853 * gnutls.c (Qgnutls_dll): Define.
16854 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
16855 (gnutls_*): Declare function pointers.
16856 (init_gnutls_functions): New function to initialize function pointers.
16857 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
16858 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
16859 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
16860 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
16861 (emacs_gnutls_write, emacs_gnutls_read)
16862 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
16863 (Fgnutls_available_p): New function.
16864 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
16865 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
16866 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
16868 * image.c: Include w32.h.
16869 (Vimage_type_cache): Delete.
16870 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
16871 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
16872 (w32_delayed_load): Move to w32.c.
16874 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
16876 * w32.c (QCloaded_from, Vlibrary_cache): Define.
16877 (w32_delayed_load): Move from image.c. When loading a library, record
16878 its filename in the :loaded-from property of the library id.
16879 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
16880 Initialize and staticpro them.
16881 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
16883 * process.c: Include lisp.h before w32.h, not after.
16884 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
16885 instead of gnutls_record_check_pending.
16887 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
16889 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
16891 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
16892 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
16895 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
16897 * xterm.c (x_set_frame_alpha): Do not set property on anything
16898 else than FRAME_X_OUTER_WINDOW (Bug#8608).
16900 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16902 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
16904 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
16906 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
16907 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

16913 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
16914 (Qgnutls_bootprop_callbacks_verify): Make static.
16916 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
16918 * callproc.c: Indentation fixup.
16920 * sysdep.c (wait_for_termination_1): Make static.
16921 (wait_for_termination, interruptible_wait_for_termination):
16922 Move after wait_for_termination_1.
16924 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
16926 * sysdep.c (interruptible_wait_for_termination): New function
16927 which is like wait_for_termination, but allows keyboard
16930 * callproc.c (Fcall_process): Add (:file "file") as an option for
16932 (Fcall_process_region): Ditto.
16934 2011-04-30 Eli Zaretskii <eliz@gnu.org>
16936 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
16937 rather than `XVECTOR (FOO)->size'.
16939 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
16940 inttypes.h, as a gnulib replacement is used if it not available in
16943 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16945 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
16946 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
16947 of MOST_POSITIVE_FIXNUM. (Bug#8528)
16949 * coding.c (coding_alloc_by_realloc): Error out if destination
16950 will grow beyond MOST_POSITIVE_FIXNUM.
16951 (decode_coding_emacs_mule): Abort if there isn't enough place in
16952 charbuf for the composition carryover bytes. Reserve an extra
16953 space for up to 2 characters produced in a loop.
16954 (decode_coding_iso_2022): Abort if there isn't enough place in
16955 charbuf for the composition carryover bytes.
16957 2011-04-21 Eli Zaretskii <eliz@gnu.org>
16959 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
16960 aborting when %lld or %lll format is passed.
16961 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
16962 %llo or %llx format is passed. (Bug#8545)
16964 * window.c (window_scroll_line_based): Use a marker instead of
16965 simple variables to record original value of point. (Bug#7952)
16967 * doprnt.c (doprnt): Fix the case where a multibyte sequence
16968 produced by %s or %c overflows available buffer space. (Bug#8545)
16970 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
16972 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
16973 (SIZE_MAX): Move defn after all includes, as they might #define it.
16975 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16977 * w32.c (init_environment): Warn about defaulting HOME to C:\.
16979 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16981 * keyboard.c (Qdelayed_warnings_hook): Define.
16982 (command_loop_1): Run `delayed-warnings-hook'
16983 if Vdelayed_warnings_list is non-nil.
16984 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
16985 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
16987 2011-04-28 Eli Zaretskii <eliz@gnu.org>
16989 * doprnt.c (doprnt): Don't return value smaller than the buffer
16990 size if the message was truncated. (Bug#8545).
16992 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
16994 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
16995 (Fx_window_property): #if-0 the whole functions, not just the bodies.
16997 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
16999 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
17001 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
17003 * makefile.w32-in: Update dependencies.
17005 2011-04-27 Eli Zaretskii <eliz@gnu.org>
17007 Improve `doprnt' and its usage. (Bug#8545)
17008 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
17009 `format_end'. Remove support for %l as a conversion specifier.
17010 Don't use xrealloc. Improve diagnostics when the %l size modifier
17011 is used. Update the commentary.
17013 * eval.c (verror): Simplify calculation of size_t.
17015 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
17018 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
17020 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
17023 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
17025 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
17026 This makes this file independent of the recent pseudovector change.
17028 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
17030 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
17032 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
17033 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
17034 Remove unused local.
17035 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
17037 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
17038 GCC 4.6.0 optimizes based on type-based alias analysis.
17039 For example, if b is of type struct buffer * and v of type struct
17040 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
17041 != &v->size, and therefore "v->size = 1; b->size = 2; return
17042 v->size;" must therefore return 1. This assumption is incorrect
17043 for Emacs, since it type-puns struct Lisp_Vector * with many other
17044 types. To fix this problem, this patch adds a new type struct
17045 vectorlike_header that documents the constraints on layout of vectors
17046 and pseudovectors, and helps optimizing compilers not get fooled
17047 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
17048 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
17049 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
17051 (XSETPVECTYPE): Rewrite in terms of new macro.
17052 (XSETPVECTYPESIZE): New macro, specifying both type and size.
17053 This is a bit clearer, and further avoids the possibility of
17054 undesirable aliasing.
17055 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
17056 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
17057 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
17058 since Lisp_Subr is a special case (no "next" field).
17059 (ASIZE): Now uses header.size rather than size.
17060 All previous uses of XVECTOR (foo)->size replaced to use this macro,
17061 to avoid the hassle of writing XVECTOR (foo)->header.size.
17062 (struct vectorlike_header): New type.
17063 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
17064 object, to help avoid aliasing.
17065 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
17066 (SUBRP): Likewise, since Lisp_Subr is a special case.
17067 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
17068 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
17069 (struct Lisp_Hash_Table): Combine first two members into a single
17070 struct vectorlike_header member. All uses of "size" and "next" members
17071 changed to be "header.size" and "header.next".
17072 * buffer.h (struct buffer): Likewise.
17073 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
17074 * frame.h (struct frame): Likewise.
17075 * process.h (struct Lisp_Process): Likewise.
17076 * termhooks.h (struct terminal): Likewise.
17077 * window.c (struct save_window_data, struct saved_window): Likewise.
17078 * window.h (struct window): Likewise.
17079 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
17080 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
17081 * buffer.c (init_buffer_once): Likewise.
17082 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
17084 * process.c (Fformat_network_address): Use local var for size,
17087 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
17089 Make the Lisp reader and string-to-float more consistent (Bug#8525)
17090 * data.c (atof): Remove decl; no longer used or needed.
17091 (digit_to_number): Move to lread.c.
17092 (Fstring_to_number): Use new string_to_number function, to be
17093 consistent with how the Lisp reader treats infinities and NaNs.
17094 Do not assume that floating-point numbers represent EMACS_INT
17095 without losing information; this is not true on most 64-bit hosts.
17096 Avoid double-rounding errors, by insisting on integers when
17097 parsing non-base-10 numbers, as the documentation specifies.
17098 * lisp.h (string_to_number): New decl, replacing ...
17099 (isfloat_string): Remove.
17100 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
17101 (read1): Do not accept +. and -. as integers; this
17102 appears to have been a coding error. Similarly, do not accept
17103 strings like +-1e0 as floating point numbers. Do not report
17104 overflow for integer overflows unless the base is not 10 which
17105 means we have no simple and reliable way to continue.
17106 Break out the floating-point parsing into a new
17107 function string_to_number, so that Fstring_to_number parses
17108 floating point numbers consistently with the Lisp reader.
17109 (digit_to_number): Move here from data.c. Make it static inline.
17110 (E_CHAR, EXP_INT): Remove, replacing with ...
17111 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
17112 (string_to_number): New function, replacing isfloat_string.
17113 This function checks for valid syntax and produces the resulting
17114 Lisp float number too. Rework it so that string-to-number
17115 no longer mishandles examples like "1.0e+". Use strtoumax,
17116 so that overflow for non-base-10 numbers is reported only when
17117 there's no portable and simple way to convert to floating point.
17119 * textprop.c (set_text_properties_1): Rewrite for clarity,
17120 and to avoid GCC warning about integer overflow.
17122 * intervals.h (struct interval): Use EMACS_INT for members
17123 where EMACS_UINT might cause problems. See
17124 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
17125 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
17126 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
17128 (offset_intervals): Tell GCC not to worry about length overflow
17129 when negating a negative length.
17131 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
17132 (overrun_check_free): Likewise.
17134 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
17135 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
17138 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17139 (gnutls_make_error): Rename local to avoid shadowing.
17140 (gnutls_emacs_global_deinit): ifdef out; not used.
17141 (Fgnutls_boot): Use const for pointer to readonly storage.
17142 Comment out unused local. Fix pointer signedness problems.
17144 * lread.c (openp): Don't stuff size_t into an 'int'.
17145 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
17146 about possible signed overflow.
17148 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
17149 (GDK_KEY_g): Don't define if already defined.
17150 (xg_prepare_tooltip): Avoid pointer signedness problem.
17151 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
17153 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
17154 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
17156 * xfns.c (Fx_window_property): Simplify a bit,
17157 to make a bit faster and to avoid GCC 4.6.0 warning.
17158 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
17160 * fns.c (internal_equal): Don't assume size_t fits in int.
17162 * alloc.c (compact_small_strings): Tighten assertion a little.
17164 Replace pEd with more-general pI, and fix some printf arg casts.
17165 * lisp.h (pI): New macro, generalizing old pEd macro to other
17166 conversion specifiers. For example, use "...%"pI"d..." rather
17167 than "...%"pEd"...".
17168 (pEd): Remove. All uses replaced with similar uses of pI.
17169 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
17170 * alloc.c (check_pure_size): Don't overflow by converting size to int.
17171 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
17172 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
17173 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
17174 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
17175 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
17177 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
17178 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
17179 * print.c (safe_debug_print, print_object): Likewise.
17180 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
17182 Use pI instead of if-then-else-abort. Use %p to avoid casts,
17183 avoiding the 0 flag, which is not portable.
17184 * process.c (Fmake_network_process): Use pI to avoid cast.
17185 * region-cache.c (pp_cache): Likewise.
17186 * xdisp.c (decode_mode_spec): Likewise.
17187 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
17188 behavior on 64-bit hosts with printf arg.
17189 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
17190 (x_stop_queuing_selection_requests): Likewise.
17191 (x_get_window_property): Don't truncate byte count to an 'int'
17194 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
17195 here, since it parses constructs like leading '-' and spaces,
17196 which are not wanted; and it overflows with large numbers.
17197 Instead, simply match F[0-9]+, which is what is wanted anyway.
17199 * alloc.c: Remove unportable assumptions about struct layout.
17200 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
17201 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
17202 (allocate_vectorlike, make_pure_vector): Use the new macros,
17203 plus offsetof, to remove unportable assumptions about struct layout.
17204 These assumptions hold on all porting targets that I know of, but
17205 they are not guaranteed, they're easy to remove, and removing them
17206 makes further changes easier.
17208 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
17209 This doesn't fix a bug but makes the code clearer.
17210 (string_overrun_cookie): Now const. Use initializers that
17211 don't formally overflow signed char, to avoid warnings.
17212 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
17213 can cause Emacs to crash when string overrun checking is enabled.
17214 (allocate_buffer): Don't assume sizeof (struct buffer) is a
17215 multiple of sizeof (EMACS_INT); it need not be, if
17216 alignof(EMACS_INT) < sizeof (EMACS_INT).
17217 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
17219 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

17223 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
17225 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
17226 supposed to be handshaking. (Bug#8556)
17227 Reported by Paul Eggert <eggert@cs.ucla.edu>.
17229 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
17231 * lisp.h (Qdebug): List symbol.
17232 * eval.c (Qdebug): Restore global linkage.

17234 (handle_user_signal): Break into debugger when debug-on-event
17235 matches the current signal symbol.
17237 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
17239 * alloc.c (check_sblock, check_string_bytes)
17240 (check_string_free_list): Convert to standard C.
17242 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
17244 * w32.c (emacs_gnutls_push): Fix typo.
17246 2011-04-25 Eli Zaretskii <eliz@gnu.org>
17248 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
17249 "cast to pointer from integer of different size".
17251 Improve doprnt and its use in verror. (Bug#8545)
17252 * doprnt.c (doprnt): Document the set of format control sequences
17253 supported by the function. Use SAFE_ALLOCA instead of always
17256 * eval.c (verror): Don't limit the buffer size at size_max-1, that
17257 is one byte too soon. Don't use xrealloc; instead xfree and
17260 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
17262 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
17265 * gnutls.c: Renamed global_initialized to
17266 gnutls_global_initialized. Added internals for the
17267 :verify-hostname-error, :verify-error, and :verify-flags
17268 parameters of `gnutls-boot' and documented those parameters in the
17269 docstring. Start callback support.
17270 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
17271 unless a fatal error occurred. Call gnutls_alert_send_appropriate
17272 on error. Return error code.
17273 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
17274 (emacs_gnutls_read): Likewise.
17275 (Fgnutls_boot): Return handshake error code.
17276 (emacs_gnutls_handle_error): New function.
17277 (wsaerror_to_errno): Likewise.

17332 changes in globals.h immediately force recompilation.
17333 (TAGS): Depend on $(CURDIR)/m/intel386.h and
17334 $(CURDIR)/s/ms-w32.h.

17339 <char-direction-table>: Deleted.
17341 2011-04-23 Eli Zaretskii <eliz@gnu.org>
17343 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
17344 * doprnt.c: Include limits.h.
17345 (SIZE_MAX): New macro.
17346 (doprnt): Return a size_t value. 2nd arg is now size_t.
17347 Many local variables are now size_t instead of int or unsigned.
17348 Improve overflow protection. Support `l' modifier for integer
17349 conversions. Support %l conversion. Don't assume an EMACS_INT
17350 argument for integer conversions and for %c.
17352 * lisp.h (doprnt): Restore prototype.
17354 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
17355 $(SRC)/character.h.
17357 * Makefile.in (base_obj): Add back doprnt.o.
17359 * deps.mk (doprnt.o): Add back prerequisites.
17360 (callint.o): Depend on character.h.
17362 * eval.c (internal_lisp_condition_case): Include the handler
17363 representation in the error message.
17364 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
17365 when breaking from the loop.
17367 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
17369 * callint.c (Fcall_interactively): When displaying error message
17370 about invalid control letter, pass the character's codepoint, not
17371 a pointer to its multibyte form. Improve display of the character
17372 in octal and display also its hex code.
17374 * character.c (char_string): Use %x to display the (unsigned)
17375 codepoint of an invalid character, to avoid displaying a bogus
17378 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
17379 `error', not SYMBOL_NAME itself.
17381 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
17382 character arguments to `error'.
17384 * charset.c (check_iso_charset_parameter): Fix incorrect argument
17385 to `error' in error message about FINAL_CHAR argument. Make sure
17386 FINAL_CHAR is a character, and use %c when it is passed as
17387 argument to `error'.
17389 2011-04-23 Eli Zaretskii <eliz@gnu.org>

17577 ns_descriptor_to_entity that were caused by using free to
17578 deallocate memory blocks that were allocated by xmalloc (via
17579 xstrdup). This caused Emacs to crash when compiled with

17937 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
17938 * dispextern.h (bidi_dump_cached_states): Remove, since it's
17939 exported only to the debugger.
17941 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
17942 * atimer.h (run_all_atimers): Remove; not exported.
17944 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
17945 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
17946 was inaccessible from Lisp.
17947 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
17948 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
17950 alloc.c: Import and export fewer symbols, and remove unused items.
17951 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
17953 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
17954 it's not optimized away by whole-program optimization.

17966 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
17967 (mark_backtrace): Define only if BYTE_MARK_STACK.
17968 * xdisp.c (message_enable_multibyte): Now static.
17970 Declare Lisp_Object Q* variables to be 'static' if not exported.
17971 This makes it easier for human readers (and static analyzers)
17972 to see whether these variables are used from other modules.
17973 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

17983 Remove decls of unexported vars.
17984 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
17986 * lisp.h (DEFINE_FUNC): Make sname 'static'.
17988 Make Emacs functions such as Fatom 'static' by default.
17989 This makes it easier for human readers (and static analyzers)
17990 to see whether these functions can be called from other modules.
17991 DEFUN now defines a static function. To make the function external
17992 so that it can be used in other C modules, use the new macro DEFUE.
17993 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
17994 (Finit_image_library):
17995 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

17997 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
17998 Remove decls, since these functions are now static.
17999 (Funintern, Fget_internal_run_time): New decls, since these functions
18000 were already external.
18002 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

18010 Mark functions with DEFUE instead of DEFUN,
18011 if they are used in other modules.
18012 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
18013 decls for now-static functions.
18014 * buffer.h (Fdelete_overlay): Remove decl.

18024 * image.c (Finit_image_library): New forward static decl.
18025 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
18026 * intervals.h (Fprevious_property_change):
18027 (Fremove_list_of_text_properties): Remove decls.
18028 * keyboard.c (Fthis_command_keys): Remove decl.
18029 (Fcommand_execute): New forward static decl.

18050 2011-04-13 Eli Zaretskii <eliz@gnu.org>
18052 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
18053 when at ZV. (Bug#8487)
18055 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
18057 * charset.c (Fclear_charset_maps): Use xfree instead of free.

18063 * xsettings.c (read_and_apply_settings): Likewise.
18065 * alloc.c (overrun_check_malloc, overrun_check_realloc)
18066 (overrun_check_free): Protoize.
18068 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
18070 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
18071 since callers should never pass a negative size.
18072 Change the signature to match that of plain 'read' and 'write'; see
18073 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
18074 * lisp.h: Update prototypes of emacs_write and emacs_read.
18076 2011-04-11 Eli Zaretskii <eliz@gnu.org>
18078 * xdisp.c (redisplay_window): Don't try to determine the character
18079 position of the scroll margin if the window start point w->startp
18080 is outside the buffer's accessible region. (Bug#8468)
18082 2011-04-10 Eli Zaretskii <eliz@gnu.org>
18084 Fix write-region and its subroutines for buffers > 2GB.
18085 * fileio.c (a_write, e_write): Modify declaration of arguments and
18086 local variables to support buffers larger than 2GB.
18087 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
18089 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
18090 argument, local variables, and return value.
18092 * lisp.h: Update prototypes of emacs_write and emacs_read.
18094 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
18096 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
18098 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
18100 Fix more problems found by GCC 4.6.0's static checks.
18102 * xdisp.c (vmessage): Use a better test for character truncation.
18104 * charset.c (load_charset_map): <, not <=, for optimization,
18105 and to avoid potential problems with integer overflow.
18106 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
18107 * casetab.c (set_identity, shuffle): Likewise.
18108 * editfns.c (Fformat): Likewise.
18109 * syntax.c (skip_chars): Likewise.
18111 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
18112 This also lets GCC 4.6.0 generate slightly better loop code.
18114 * callint.c (Fcall_interactively): <, not <=, for optimization.
18115 (Fcall_interactively): Count the number of arguments produced,
18116 not the number of arguments given. This is simpler and lets GCC
18117 4.6.0 generate slightly better code.
18119 * ftfont.c: Distingish more carefully between FcChar8 and char.
18120 The previous code passed unsigned char * to a functions like
18121 strlen and xstrcasecmp that expect char *, which does not
18122 conform to the C standard.
18123 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
18124 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
18125 char * when the C standard requires it.
18127 * keyboard.c (read_char): Remove unused var.
18129 * eval.c: Port to Windows vsnprintf (Bug#8435).
18130 Include <limits.h>.
18131 (SIZE_MAX): Define if the headers do not.
18132 (verror): Do not give up if vsnprintf returns a negative count.
18133 Instead, grow the buffer. This ports to Windows vsnprintf, which
18134 does not conform to C99. Problem reported by Eli Zaretskii.
18135 Also, simplify the allocation scheme, by avoiding the need for
18136 calling realloc, and removing the ALLOCATED variable.
18138 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
18140 Remove invocations of doprnt, as Emacs now uses vsnprintf.
18141 But keep the doprint source code for now, as we might revamp it
18142 and use it again (Bug#8435).
18143 * lisp.h (doprnt): Remove.
18144 * Makefile.in (base_obj): Remove doprnt.o.
18145 * deps.mk (doprnt.o): Remove.
18147 error: Print 32- and 64-bit integers portably (Bug#8435).
18148 Without this change, on typical 64-bit hosts error ("...%d...", N)
18149 was used to print both 32- and 64-bit integers N, which relied on
18150 undefined behavior.
18151 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
18152 * lisp.h (error, verror): Mark as printf-like functions.
18153 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
18154 Report overflow in size calculations when allocating printf buffer.
18155 Do not truncate output string at its first null byte.
18156 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
18157 Truncate the output at a character boundary, since vsnprintf does not
18159 * charset.c (check_iso_charset_parameter): Convert internal
18160 character to string before calling 'error', since %c now has the
18162 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
18163 overflow when computing char to be passed to 'error'. Do not
18164 pass Lisp_Object to 'error'; pass the integer instead.
18165 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
18166 formatted with plain %d.
18168 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
18170 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
18172 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
18174 * xterm.c (x_catch_errors): Remove duplicate declaration.
18176 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
18178 * xdisp.c, lisp.h (message_nolog): Remove; unused.
18180 2011-04-10 Jim Meyering <meyering@redhat.com>
18182 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
18183 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
18184 return ssize_t not "int", and use size_t as the buffer length.
18185 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
18186 * gnutls.h: Update declarations.
18187 * process.c (read_process_output): Use ssize_t, to match.
18188 (send_process): Likewise.
18190 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18192 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
18194 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
18196 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
18197 Use unsigned char, to match FcChar8 type definition.
18199 * xterm.c (handle_one_xevent):
18200 * xmenu.c (create_and_show_popup_menu):
18201 * xselect.c (x_decline_selection_request)
18202 (x_reply_selection_request): Avoid type-punned deref of X events.
18204 2011-04-09 Eli Zaretskii <eliz@gnu.org>
18206 Fix some uses of `int' instead of EMACS_INT.
18207 * search.c (string_match_1, fast_string_match)
18208 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
18209 (scan_buffer, find_next_newline_no_quit)
18210 (find_before_next_newline, search_command, Freplace_match)
18211 (Fmatch_data): Make some `int' variables be EMACS_INT.
18213 * xdisp.c (display_count_lines): 3rd argument and return value now
18214 EMACS_INT. All callers changed.
18215 (pint2hrstr): Last argument is now EMACS_INT.
18217 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
18218 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
18219 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

18230 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
18231 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
18233 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
18234 (encode_invocation_designation): Last argument P_NCHARS is now
18236 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
18237 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
18239 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
18242 * ccl.c (Fccl_execute_on_string): Declare some variables
18245 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
18247 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
18249 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
18251 * process.c (Fformat_network_address): Doc fix.
18253 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
18255 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
18257 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
18259 * keyboard.c (read_char): Call Lisp function help-form-show,
18260 instead of using internal_with_output_to_temp_buffer.
18261 (Qhelp_form_show): New var.
18262 (syms_of_keyboard): Use DEFSYM macro.
18264 * print.c (internal_with_output_to_temp_buffer): Function deleted.

18271 (list_processes_1): Delete.
18273 2011-04-06 Eli Zaretskii <eliz@gnu.org>

18277 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
18279 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
18281 Fix more problems found by GCC 4.6.0's static checks.
18283 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
18285 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
18287 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
18289 * xdisp.c (vmessage): Mark as a printf-like function.
18291 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

18295 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
18296 printf-like functions.
18297 (tiff_load): Add casts to remove these marks before passing them
18298 to system-supplied API.
18300 * eval.c (Fsignal): Remove excess argument to 'fatal'.
18302 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
18303 This avoids several warnings with gcc -Wstrict-overflow.
18304 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
18305 directly, rather than having caller test rule sign. This avoids
18306 some unnecessary tests.
18307 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
18308 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
18309 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
18311 * xfont.c (xfont_text_extents): Remove var that was set but not used.
18312 (xfont_open): Avoid unnecessary tests.
18314 * composite.c (composition_gstring_put_cache): Use unsigned integer.
18316 * composite.h, composite.c (composition_gstring_put_cache):
18317 Use EMACS_INT, not int, for length.
18319 * composite.h (COMPOSITION_DECODE_REFS): New macro,
18320 breaking out part of COMPOSITION_DECODE_RULE.
18321 (COMPOSITION_DECODE_RULE): Use it.
18322 * composite.c (get_composition_id): Remove unused local vars,
18323 by using the new macro.
18325 * textprop.c (set_text_properties_1): Change while to do-while,
18326 since the condition is always true at first.
18328 * intervals.c (graft_intervals_into_buffer): Mark var as used.
18329 (interval_deletion_adjustment): Return unsigned value.
18332 * process.c (list_processes_1, create_pty, read_process_output):
18333 (exec_sentinel): Remove vars that were set but not used.
18334 (create_pty): Remove unnecessary "volatile"s.
18335 (Fnetwork_interface_info): Avoid possibility of int overflow.
18336 (read_process_output): Do adaptive read buffering even if carryover.
18337 (read_process_output): Simplify nbytes computation if buffered.
18339 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
18341 * syntax.c (scan_words): Remove var that was set but not used.
18342 (update_syntax_table): Use unsigned instead of int.
18344 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
18345 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
18346 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
18348 * print.c (print_error_message): Avoid int overflow.
18350 * font.c (font_list_entities): Redo for clarity,
18351 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
18353 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
18354 (font_score): Avoid potential overflow in diff calculation.
18356 * fns.c (substring_both): Remove var that is set but not used.
18357 (sxhash): Redo loop for clarity and to avoid wraparound warning.
18359 * eval.c (funcall_lambda): Rename local to avoid shadowing.
18361 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
18362 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
18363 can always succeed if overflow has undefined behavior.
18365 * search.c (boyer_moore, wordify): Remove vars set but not used.
18366 (wordify): Omit three unnecessary tests.
18368 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
18369 All callers changed. This avoids the need for an unused var.
18371 * casefiddle.c (casify_region): Remove var that is set but not used.
18373 * dired.c (file_name_completion): Remove var that is set but not used.
18375 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
18377 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
18378 (Finsert_file_contents): Remove unnecessary code checking fd.
18380 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
18381 Check for integer overflow on size calculations.
18383 * buffer.c (Fprevious_overlay_change): Remove var that is set
18386 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
18387 Remove vars that are set but not used.
18388 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
18389 (timer_check_2): Mark vars as initialized.
18391 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
18393 * image.c (lookup_image): Remove var that is set but not used.
18394 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
18396 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
18397 that are set but not used.
18399 * xfns.c (make_invisible_cursor): Don't return garbage
18400 if XCreateBitmapFromData fails (Bug#8410).
18402 * xselect.c (x_get_local_selection, x_handle_property_notify):
18403 Remove vars that are set but not used.
18405 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
18406 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
18408 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
18409 Remove var that is set but not used.
18410 (scroll_bar_windows_size): Now size_t, not int.
18411 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
18412 Check for overflow.
18414 * xfaces.c (realize_named_face): Remove vars that are set but not used.
18415 (map_tty_color) [!defined MSDOS]: Likewise.
18417 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
18419 * coding.c: Remove vars that are set but not used.
18420 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
18421 All callers changed.
18422 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
18423 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
18424 (decode_coding_charset): Remove vars that are set but not used.
18426 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
18427 that is set but not used.
18429 * print.c (print_object): Remove var that is set but not used.
18431 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
18432 The gnulib version avoids calling malloc in the usual case,
18433 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
18434 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
18435 * filelock.c (current_lock_owner): Likewise.
18436 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
18437 * sysdep.c: Include allocator.h, careadlinkat.h.
18438 (emacs_no_realloc_allocator): New static constant.
18439 (emacs_readlink): New function.
18440 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
18441 ../lib/careadlinkat.h.
18443 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
18445 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
18446 first non-nil return value).
18448 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
18450 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
18451 if not defined (Bug#8403).
18453 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18455 * xdisp.c (display_count_lines): Remove parameter `start',
18456 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18457 (get_char_face_and_encoding): Remove parameter `multibyte_p',
18458 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

18460 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
18461 and thereabouts. All callers changed.
18462 (get_per_char_metric): Remove parameter `f', unused since
18463 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
18465 2011-04-02 Jim Meyering <meyering@redhat.com>
18467 do not dereference NULL upon failed strdup
18468 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
18469 (ns_get_family): Likewise.
18471 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
18473 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
18475 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
18477 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
18480 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
18482 Add lexical binding.
18484 * window.c (Ftemp_output_buffer_show): New fun.
18485 (Fsave_window_excursion):
18486 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
18488 * lread.c (lisp_file_lexically_bound_p): New function.
18489 (Fload): Bind Qlexical_binding.
18490 (readevalloop): Remove `evalfun' arg.
18491 Bind Qinternal_interpreter_environment.
18492 (Feval_buffer): Bind Qlexical_binding.
18493 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
18495 (syms_of_lread): Declare `lexical-binding'.
18497 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
18499 * keyboard.c (eval_dyn): New fun.
18500 (menu_item_eval_property): Use it.
18502 * image.c (parse_image_spec): Use Ffunctionp.
18504 * fns.c (concat, mapcar1): Accept byte-code-functions.
18506 * eval.c (Fsetq): Handle lexical vars.
18507 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
18508 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
18509 (FletX, Flet): Obey lexical binding.
18510 (Fcommandp): Handle closures.
18511 (Feval): New `lexical' arg.
18512 (eval_sub): New function extracted from Feval. Use it almost
18513 everywhere where Feval was used. Look up vars in lexical env.
18515 (Ffunctionp): Move from subr.el.
18516 (Ffuncall): Handle closures.
18517 (apply_lambda): Remove `eval_flags'.
18518 (funcall_lambda): Handle closures and new byte-code-functions.
18519 (Fspecial_variable_p): New function.
18520 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
18521 but without exporting it to Lisp.
18523 * doc.c (Fdocumentation, store_function_docstring):
18524 * data.c (Finteractive_form): Handle closures.
18526 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
18529 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
18531 (exec_byte_code): New function extracted from Fbyte_code to handle new
18532 calling convention for byte-code-functions. Add new byte-codes.
18534 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
18536 * alloc.c (Fmake_symbol): Init new `declared_special' field.
18538 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18540 * xdisp.c (redisplay_internal): Fix prototype.
18542 2011-03-31 Eli Zaretskii <eliz@gnu.org>
18544 * xdisp.c (SCROLL_LIMIT): New macro.
18545 (try_scrolling): Use it when setting scroll_limit.
18546 Limit scrolling to 100 screen lines.
18547 (redisplay_window): Even when falling back on "recentering",
18548 position point in the window according to scroll-conservatively,
18549 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
18551 (try_scrolling): When point is above the window, allow searching
18552 as far as scroll_max, or one screenful, to compute vertical
18553 distance from PT to the scroll margin position. This prevents
18554 try_scrolling from unnecessarily failing when
18555 scroll-conservatively is set to a value slightly larger than the
18556 window height. Clean up the case of PT below the margin at bottom
18557 of window: scroll_max can no longer be INT_MAX. When aggressive
18558 scrolling is in use, don't let point enter the opposite scroll
18559 margin as result of the scroll.
18560 (syms_of_xdisp) <scroll-conservatively>: Document the
18561 threshold of 100 lines for never-recentering scrolling.
18563 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
18565 * dispextern.h (move_it_by_lines):
18566 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

18568 (message_log_check_duplicate): Remove parameters `prev_bol' and
18569 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
18570 (redisplay_internal): Remove parameter `preserve_echo_area',
18571 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
18573 * indent.c (Fvertical_motion):
18574 * window.c (window_scroll_pixel_based, Frecenter):
18575 Don't pass `need_y_p' to `move_it_by_lines'.
18577 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
18579 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
18580 steal a few bits to be more compact.
18581 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
18582 Remove unneeded casts.
18584 * bytecode.c (Fbyte_code): CAR and CDR can GC.
18586 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
18588 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
18589 binding" message (bug#7967).
18591 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
18593 Fix more problems found by GCC 4.6.0's static checks.
18595 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
18596 Remove unused local var.
18598 * editfns.c (Fmessage_box): Remove unused local var.
18600 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
18601 (note_mode_line_or_margin_highlight, note_mouse_highlight):
18602 Omit unused local vars.
18603 * window.c (shrink_windows): Omit unused local var.
18604 * menu.c (digest_single_submenu): Omit unused local var.
18605 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
18606 Omit unused local var.
18608 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
18609 Don't assume string length fits in int.
18610 (keyremap_step, read_key_sequence): Use size_t for sizes.
18611 (read_key_sequence): Don't check last_real_key_start redundantly.
18613 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
18614 instead of alloca (Bug#8344).
18616 * eval.c (Fbacktrace): Don't assume nargs fits in int.
18617 (Fbacktrace_frame): Don't assume nframes fits in int.
18619 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
18621 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
18624 * term.c (produce_glyphless_glyph): Remove unnecessary test.
18626 * cm.c (calccost): Turn while-do into do-while, for clarity.
18628 * keyboard.c (syms_of_keyboard): Use the same style as later
18629 in this function when indexing through an array. This also
18630 works around GCC bug 48267.
18632 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
18634 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
18636 * chartab.c (sub_char_table_ref_and_range): Redo for slight
18637 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
18639 * keyboard.c, keyboard.h (num_input_events): Now size_t.
18640 This avoids undefined behavior on integer overflow, and is a bit
18641 more convenient anyway since it is compared to a size_t variable.
18643 Variadic C functions now count arguments with size_t, not int.
18644 This avoids an unnecessary limitation on 64-bit machines, which
18645 caused (substring ...) to crash on large vectors (Bug#8344).
18646 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
18647 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

18655 * fns.c (concat): Likewise.
18656 * frame.c (x_set_frame_parameters): Likewise.
18657 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
18658 0 if not found, not -1. All callers changed.
18660 * alloc.c (garbage_collect): Don't assume stack size fits in int.
18661 (stack_copy_size): Now size_t, not int.
18662 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
18664 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
18666 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
18667 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
18668 All callers changed.
18670 * lisp.h (multibyte_char_to_unibyte):
18671 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
18672 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

18676 * keymap.c (push_key_description):
18677 * search.c (Freplace_match):
18678 * xdisp.c (message_dolog, set_message_1): All callers changed.
18680 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
18682 * keyboard.c (safe_run_hook_funcall): New function.
18683 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
18684 don't set the hook to nil, but remove the offending function instead.
18685 (Qcommand_hook_internal): Remove, unused.
18686 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
18687 Vcommand_hook_internal.
18689 * eval.c (enum run_hooks_condition): Remove.
18690 (funcall_nil, funcall_not): New functions.
18691 (run_hook_with_args): Call each function through a `funcall' argument.
18692 Remove `cond' argument, now redundant.
18693 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
18694 (Frun_hook_with_args_until_failure): Adjust accordingly.
18695 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
18697 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

18701 * print.c (strout): Remove parameter `multibyte', unused since
18702 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
18704 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
18705 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
18706 All callers changed.
18708 * w32.c (_wsa_errlist): Use braces for struct initializers.
18710 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
18711 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
18712 All callers changed.

18867 * buffer.c (Fkill_all_local_variables):
18868 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
18870 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
18871 unconditionally since it does the check itself.
18873 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
18875 Fix more problems found by GCC 4.5.2's static checks.
18877 * coding.c (encode_coding_raw_text): Avoid unnecessary test
18878 the first time through the loop, since we know p0 < p1 then.
18879 This also avoids a gcc -Wstrict-overflow warning.
18881 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
18882 leading to a memory leak, possible in functions like
18883 load_charset_map_from_file that can allocate an unbounded number
18884 of objects (Bug#8318).
18886 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
18887 that could (at least in theory) be that large.
18889 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
18890 This is less likely to overflow, and avoids undefined behavior if
18891 overflow does occur. All callers changed. Use strtoul to scan
18892 for the unsigned long integer.
18893 (pint2hrstr): Simplify and tune code slightly.
18894 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

18909 * process.c (Fmake_network_process): Use socklen_t, not int,
18910 where POSIX says socklen_t is required in portable programs.
18911 This fixes a porting bug on hosts like 64-bit HP-UX, where
18912 socklen_t is wider than int (Bug#8277).
18913 (Fmake_network_process, server_accept_connection):
18914 (wait_reading_process_output, read_process_output):
18917 * process.c: Rename or move locals to avoid shadowing.

18927 Make tparam.h and terminfo.c consistent.
18928 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
18929 Include tparam.h instead, since it declares them.
18930 * cm.h (PC): Remove extern decl; tparam.h now does this.
18931 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
18932 * terminfo.c: Include tparam.h, to check interfaces.
18933 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
18934 (tparam): Adjust signature to match interface in tparam.h;
18935 this removes some undefined behavior. Check that outstring and len
18936 are zero, which they always are with Emacs.
18937 * tparam.h (PC, BC, UP): New extern decls.
18939 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
18940 (xftfont_open): Rename locals to avoid shadowing.

18957 (find_automatic_composition, composition_adjust_point): Likewise.
18958 (composition_update_it): Mark var as initialized.
18959 (find_automatic_composition): Mark vars as initialized,
18960 with a FIXME (Bug#8290).

18964 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
18965 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
18966 (BUF_DEC_POS): Be more systematic about renaming local temporaries
18967 to avoid shadowing.
18969 * textprop.c (property_change_between_p): Remove; unused.
18971 * intervals.c (interval_start_pos): Now static.
18973 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

18979 Fix pointer signedness.
18980 (alsa_choose_format): Remove unused local var.
18981 (wav_play): Initialize a variable to 0, to prevent undefined
18982 behavior (Bug#8278).
18984 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
18986 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
18988 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
18989 clobbering (Bug#8298).
18990 * sysdep.c (sys_subshell): Likewise.
18991 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
18993 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
18994 This should get cleaned up, so that child_setup has the
18995 same signature on all platforms.
18997 * callproc.c (call_process_cleanup): Now static.
18998 (relocate_fd): Rename locals to avoid shadowing.
19000 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
19002 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
19003 not to be necessary, and produces flickering.
19005 2011-03-20 Glenn Morris <rgm@gnu.org>
19007 * config.in: Remove file.
19009 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
19011 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
19012 are now in src/globals.h.

19053 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
19054 Define only if needed.
19056 * unexelf.c (unexec): Name an expression,
19057 to avoid gcc -Wbad-function-cast warning.
19058 Use a different way to cause a compilation error if anyone uses
19059 n rather than nn, a way that does not involve shadowing.
19060 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
19062 * deps.mk (unexalpha.o): Remove; unused.
19064 New file unexec.h, the (simple) interface for unexec (Bug#8267).

19179 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
19180 (regex_compile, re_search_2, re_match_2_internal):
19181 Remove unused local vars.

19183 which gcc can warn about.
19184 (regex_compile, re_match_2_internal): Mark locals as initialized.
19185 (RETALLOC_IF): Define only if needed.
19186 (WORDCHAR_P): Likewise. This one is never needed, but is used
19187 only in a comment talking about a compiler bug, so put inside
19188 the #if 0 of that comment.
19189 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
19190 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
19193 * search.c (boyer_moore): Rename locals to avoid shadowing.

19217 New macros, so that the caller can use some names other than
19218 gcpro1, gcpro2, etc.
19219 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
19221 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
19222 argument, for consistency with GCPRO2_VAR, etc: it is now the

19226 Rename locals to avoid shadowing.
19228 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
19229 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
19230 dired.c's scmp function, had undefined behavior.
19231 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
19232 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
19233 * buffer.h: ... to here, because these macros use current_buffer,
19234 and the new implementation with inline functions needs to have
19235 current_buffer in scope now, rather than later when the macros
19237 (downcase, upcase1): New static inline functions.
19238 (DOWNCASE, UPCASE1): Reimplement using these functions.
19239 This avoids undefined behavior in expressions like
19240 DOWNCASE (x) == DOWNCASE (y), which previously suffered
19241 from race conditions in accessing the global variables
19242 case_temp1 and case_temp2.
19243 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.

19251 * fileio.c (file_name_as_directory, directory_file_name):

19254 (file_name_as_directory): Use const pointers when appropriate.
19255 (Fexpand_file_name): Likewise. In particular, newdir might
19256 point at constant storage, so make it a const pointer.

19258 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
19260 (Fset_file_times, Finsert_file_contents, auto_save_error):

19265 to avoid shadowing.
19267 * marker.c (bytepos_to_charpos): Remove; unused.
19269 * lisp.h (verify_bytepos, count_markers): New decls,
19270 so that gcc does not warn that these functions aren't declared.
19272 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
19273 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
19274 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
19275 (copy_text): Remove unused local var.

19278 (lock_file_1): Rename local to avoid shadowing.
19280 * buffer.c (fix_overlays_before): Mark locals as initialized.
19281 (fix_start_end_in_overlays): Likewise. This function should be
19282 simplified by using pointers-to-pointers, but that's a different
19284 (switch_to_buffer_1): Now static.
19285 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
19286 (report_overlay_modification): Rename locals to avoid shadowing.

19289 Fix pointer signedness issue.
19290 (sys_subshell): Mark local as volatile if checking for lint,
19291 to suppress a gcc -Wclobbered warning that does not seem to be right.
19292 (MAXPATHLEN): Define only if needed.
19294 * process.c (serial_open, serial_configure): Move decls from here ...
19295 * systty.h: ... to here, so that they can be checked.
19297 * fns.c (get_random, seed_random): Move extern decls from here ...
19298 * lisp.h: ... to here, so that they can be checked.
19300 * sysdep.c (reset_io): Now static.
19301 (wait_for_termination_signal): Remove; unused.
19303 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

19309 (describe_map_tree):
19310 Rename locals to avoid shadowing.
