51 * insdel.c (insert_1_both): Document the arguments, instead of
52 referring to insert_1, which no longer exists.
54 * xdisp.c (message_dolog): If the *Messages* buffer is shown in

163 (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
164 (row_containing_pos): Call row_for_charpos_p instead of partially
165 doing the same. Fixes cursor positioning under longlines-mode
166 when longlines-show-effect includes more than one newline, when
167 moving the cursor vertically up.

187 * unexelf.c: Don't assume ElfW (Half) fits in int.
188 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
189 when dealing with ElfW (Half) values, since they can exceed 2**31
190 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
191 (entry_address): Omit unused NUM arg. All uses changed.
193 2013-05-07 Juri Linkov <juri@jurta.org>

241 (x_get_monitor_attributes_xinerama): New functions.
242 (Fx_display_monitor_attributes_list): New primitive.
243 (syms_of_xfns): Defsubr it.
245 * xterm.h (x_display_info): Add Xatom_net_workarea and
246 Xatom_net_current_desktop.
248 * xterm.c (x_term_init): Initialize dpyinfo->Xatom_net_workarea
249 and dpyinfo->Xatom_net_current_desktop.
251 2013-05-06 Eli Zaretskii <eliz@gnu.org>
253 * xdisp.c (pos_visible_p): Use the special code for finding the
254 beginning of a display property or overlay for any "replacing"
255 display property, not just for display strings. This solves
256 incorrect reporting of position by posn-at-point. (Bug#14241)
258 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
260 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
261 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
262 Verify that ElfW (Half) fits in int.
263 (fatal): Use same signature as lisp.h.
264 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
265 configure and build with -DUNEXELF_DEBUG without worrying about
266 other modules that use DEBUG.
267 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
268 possibly-wide integers now uses it instead of plain fprintf.
269 (entry_address): New function, which avoids problems with 32-bit
270 overflow on 64-bit hosts.
271 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
272 (round_up): Don't assume the remainder fits in int.
273 (find_section): Use bool for boolean. Simplify debug code.
274 (unexec): Don't assume file sizes fit in int or size_t.
275 Omit unnecessary trailing newline in 'fatal' format.
276 Use strerror rather than outputting decimal error number.
277 Remove unused code when emacs is not defined;
278 this file relies on Emacs now.
279 Don't assume e_phnum and e_shnum are positive.
281 * regex.c: Fix problems when DEBUG is defined.
282 (extract_number, extract_number_and_incr): Define regardless of
283 whether DEBUG is defined; that's simpler and makes the code less
284 likely to go stale in the normal case when DEBUG is not defined.
285 Return int rather than taking an int * arg. All callers changed.
286 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
287 Remove, replacing with ...
288 (DEBUG_PRINT): New macro. All callers changed.
289 (DEBUG_COMPILES_ARGUMENTS): New macro.
290 (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
291 (print_compiled_pattern, print_double_string) [DEBUG]:
292 Use prototype rather than old-style definition.
293 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
294 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
295 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
296 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
297 Don't assume ptrdiff_t, size_t, and long are the same width as int.
298 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
299 This matters only when DEBUG is defined.
301 2013-05-05 Eli Zaretskii <eliz@gnu.org>
303 * xdisp.c (set_iterator_to_next): Set the
304 ignore_overlay_strings_at_pos_p flag only if we are _really_
305 iterating over an overlay string, as indicated by the
306 current.overlay_string_index member. (Bug#14306)
308 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
310 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
311 to where it is used, to avoid autorelease issues (Bug#14050).
313 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
315 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
316 * fileio.c (syms_of_fileio): Implement this.
317 * filelock.c (create_lock_file): If symbolic links don't work, so
318 we use a regular file as a lock file, do not fsync the lock file;
321 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
323 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.
324 (syms_of_minibuf): Adjust accodingly.
326 * callint.c (Fcall_interactively): Adjust calls accordingly.
328 2013-05-04 Eli Zaretskii <eliz@gnu.org>
330 * dispextern.h (WINDOW_WANTS_HEADER_LINE_P): Verify that
331 w->contents is a buffer before computing everything else.
332 Use parentheses to disambiguate last part of the condition.
334 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
335 assertion violations. (Bug#14062)
337 2013-05-01 David Reitter <david.reitter@gmail.com>
339 * nsfns.m (ns_tooltip): Initialize.
341 2013-04-28 Eli Zaretskii <eliz@gnu.org>
343 * coding.c (decode_coding_gap): Don't remove the character before
344 a newline unless it's a CR character. (Bug#14287)
346 2013-04-28 Dan Nicolaescu <dann@gnu.org>
348 * dispextern.h (struct face): Move enum face_underline_type
349 earlier so that bitfields can be in the same word.

353 * nsfns.m (handlePanelKeys): New function.
354 (EmacsOpenPanel:performKeyEquivalent:)
355 (EmacsSavePanel:performKeyEquivalent:): Call handlePanelKeys to handle
356 arrows/function/control and copy/paste keys (Bug#14296).
358 2013-04-27 Juri Linkov <juri@jurta.org>
360 * callint.c (Fcall_interactively): Call `Qread_number' for
361 interactive code letter `n' instead of using duplicate code.
364 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
366 * systime.h (make_timeval): Declare as 'const'.
368 2013-04-27 Kenichi Handa <handa@gnu.org>
370 * font.c (font_open_entity): Always open a font of manageable
373 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
375 Port better to AIX (Bug#14258).
376 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
379 2013-04-24 Kenichi Handa <handa@gnu.org>
381 * coding.c (decode_coding_iso_2022): When an invalid escape
382 sequence is encountered, reset the invocation and designation
383 status to the safest one.
385 2013-04-22 Paul Eggert <eggert@cs.ucla.edu>
387 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
388 Without this fix, "make distclean" leaves stamp-h1 behind.
390 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
392 * w32fns.c (w32_fullscreen_rect): New function to compute the
393 window rectangle for the given fullscreen mode.
394 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
395 longer tunes the window size. This keeps the window's edges flush
396 with the screen and allows the taskbar to hide itself in fullboth.
398 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
399 window decorations and uses the entire screen.
401 * w32term.h (w32_fullscreen_rect) Add prototype.
402 (struct w32_output): Replace normal_width, normal_height,
403 normal_top, and normal_left members with a single normal_placement

409 2013-04-16 Juanma Barranquero <lekktu@gmail.com>
411 * minibuf.c (Ftest_completion): Silence compiler warning.
413 2013-04-15 Eli Zaretskii <eliz@gnu.org>
415 * w32fns.c (w32_wnd_proc): Add more assertions to investigate
418 * frame.h (WINDOW_FRAME): Protect macro and its argument with
421 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
422 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
423 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
424 parentheses where appropriate.
426 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
428 * keyboard.c (timer_start_idle): Remove no-longer-used local.
430 2013-04-14 Eli Zaretskii <eliz@gnu.org>
432 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
433 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
434 Mention in the doc string that setting these variables takes
435 effect only after a call to set-window-buffer. (Bug#14200)
437 2013-04-13 Eli Zaretskii <eliz@gnu.org>
439 * indent.c (Fvertical_motion): Don't consider display strings on
440 overlay strings as display strings on the buffer position we
441 started from. This prevents vertical cursor motion from jumping
442 more than one line when there's an overlay string with a display
443 property at end of line.
444 Reported by Karl Chen <Karl.Chen@quarl.org> in
445 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.
447 2013-04-12 Stefan Monnier <monnier@iro.umontreal.ca>
449 * window.c (select_window): `record_buffer' even if window is
450 already selected (bug#14191).
452 2013-04-11 Eli Zaretskii <eliz@gnu.org>
454 * window.c (Fwindow_end): Test more flags, including the buffer's
455 last_overlay_modified flag, to determine whether the window's
456 display is really up-to-date. Prevents the function from
457 returning a stale value. (Bug#14170)
458 (Fwindow_line_height): Fix the test for up-to-date-ness of the
461 2013-04-10 Eli Zaretskii <eliz@gnu.org>
463 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
464 garbaged only if it is not already the top frame on its TTY.
465 This prevents flickering due to constant redrawing of TTY frames when
466 there are GUI frames open in the same session. (Bug#13864)
468 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
470 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
471 of marking the idle timers directly.
473 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
475 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
478 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>
480 * window.c (select_window): Don't record_buffer while the invariant is
481 temporarily broken (bug#14161).
483 * fns.c (Fdelq): Don't assume !NILP => CONSP.
485 2013-04-07 Eli Zaretskii <eliz@gnu.org>

493 (Fcopy_file, Fset_file_acl) [HAVE_POSIX_ACL]: Use it.
495 2013-03-31 Jan Djärv <jan.h.d@swipnet.se>
497 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
500 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
502 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
503 This bug was introduced by my 2013-02-25 change that simplified

505 an Emacs configured with --enable-profiling fails immediately
506 due to a profiler signal.
507 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
508 with these flags. On platforms where special flags are needed

586 This makes it easier to visualize quantities on a number line.
587 This patch doesn't apply to all such range checks,
588 only to the range checks affected by the 2013-03-24 change.
589 This patch reverts most of the 2013-03-24 change.

973 * dispnew.c, frame.c, w32fns.c, window.c, xdisp.c, xfns.c:
974 Adjust users where appropriate.
976 2013-03-20 Dmitry Antipov <dmantipov@yandex.ru>
978 * frame.h (struct frame): Drop resx and resy because the same data is
979 available from window system-specific output context. Adjust users.

1058 * coding.c (detect_ascii): New function.
1059 (detect_coding): Set coding->head_ascii and coding->eol_seen only
1060 when the source bytes are actually scanned. On detecting for
1061 coding_category_utf_8_auto, call detect_ascii instead of scanning
1062 source bytes directly.
1063 (produce_chars): Call insert_from_gap with the new arg 0.
1064 (encode_coding): Likewise.
1065 (decode_coding_gap): Control ASCII optimization by the variable

1092 f->want_fullscreen flag after changing the frame size. If the
1093 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
1096 2013-03-13 Daniel Colascione <dancol@dancol.org>
1098 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
1099 too so that these builds can use Cygwin's file conversion
1100 functions. (We've been building and linking cygw32.o all along
1101 and just not using it.)
1103 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1105 File synchronization fixes (Bug#13944).

1114 2013-03-13 Eli Zaretskii <eliz@gnu.org>
1116 * w32term.c (w32_read_socket): If the Emacs frame is being
1117 activated, call w32fullscreen_hook, to make sure the new frame
1118 dimensions are in effect. (Bug#13937)
1120 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1122 * xdisp.c (init_iterator): Simplify because both character and byte
1123 positions are either specified or -1. Add eassert. Adjust comment.
1124 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1125 character and byte positions can be obtained from marker.

1142 a function pointer type; the C Standard requires this.
1144 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
1145 Include <sys/param.h> unconditionally, as that works elsewhere and
1146 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1147 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
1150 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

1179 common file dialog code.
1181 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
1182 can just use du like other systems.
1184 * coding.c (from_unicode_buffer): Declare.

1233 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
1234 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1235 from Elisp via unread-command-events.
1237 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1238 functions to mean "no change".
1240 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1242 region-cache.c, scroll.c, search.c: Use bool for booleans.

1248 (search_regs_saved, Fregexp_quote):
1249 Use bool for boolean.
1250 * region-cache.c (region_cache_forward, region_cache_backward):
1251 Fix comments to match code: these functions return int, not boolean.
1253 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1255 * search.c (find_newline): Accept start and end byte positions
1256 as arguments and allow -1 if not known.
1257 (find_newline_no_quit): Likewise for start position.
1258 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
1259 * bidi.c (bidi_find_paragraph_start): Pass byte position to

1262 Adjust call to find_newline.
1263 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

1290 * bidi.c (bidi_fetch_char): Swap first and second arguments
1291 to match other functions accepting character and byte positions.
1293 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
1294 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
1295 when you need just to move to the previous buffer position.
1296 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1298 2013-03-07 Eli Zaretskii <eliz@gnu.org>
1300 * .gdbinit (prowlims): Display the enabled_p flag of the row.

1310 (vmotion): Use byte position argument and avoid call to CHAR_TO_BYTE.
1311 Adjust comments, style and calls to compute_motion.

1315 (window_scroll_line_based): Likewise with call to compute_motion.
1317 (Frecenter): Adjust calls to vmotion.
1319 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>

1367 (decode_coding, encode_coding): Add USE_SAFE_ALLOCA and SAFE_FREE.
1368 (decode_coding_object): Simplify since xrealloc never returns NULL.
1371 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1373 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1374 * sysdep.c (list_system_processes)
1375 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1376 Make it a stub in this case; otherwise the build might fail,
1377 and this code hasn't been tested on such hosts anyway.
1378 Problem reported by Nelson H. F. Beebe in
1379 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1380 and analyzed by Jérémie Courrèges-Anglas in
1381 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1383 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1385 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1386 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1387 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1388 * bidi.c (bidi_find_paragraph_start): Likewise.
1389 * indent.c (vmotion): Likewise.
1391 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1393 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1394 * filelock.c: Include <c-ctype.h>.
1395 (MAX_LFINFO): New top-level constant.
1396 (lock_info_type): Remove members pid, boot_time. Add members at,
1397 dot, colon. Change user member to be the entire buffer, not a
1398 pointer. This allows us to handle the case where a foreign
1399 pid or boot time exceeds the local range. All uses changed.
1400 (LINKS_MIGHT_NOT_WORK): New constant.
1401 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1402 (defined_WINDOWSNT): Remove.
1403 (MAKE_LOCK_NAME, file_in_lock_file_name):
1404 Always use .#FILE (not .#-FILE) for the file lock,
1405 even if it is a regular file.
1406 (rename_lock_file): New function.
1407 (create_lock_file): Use it.
1408 (create_lock_file, read_lock_data):
1409 Prefer a symbolic link for the lock file, falling back on a
1410 regular file if symlinks don't work. Do not try to create
1411 symlinks on MS-Windows, due to security hassles. Stick with
1412 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1413 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1414 host may be using a Windowsish file system, and cannot use
1415 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1416 doesn't work. Don't fail merely because of a symlink-contents
1417 length limit in the current file system; fall back on regular
1418 files. Increase the symlink contents length limit to 8 KiB, this
1419 should be big enough for any real use and doesn't crunch the
1421 (create_lock_file, lock_file_1, read_lock_data):
1422 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1423 (lock_file_1): Return error number, not bool. All callers changed.
1424 (ELOOP): New macro, if not already defined.
1425 (read_lock_data): Return size of lock file contents, not Lisp object.
1426 All callers changed. Handle a race condition if some other process
1427 replaces a regular-file lock with a symlink lock or vice versa,
1428 while we're trying to read the lock.
1429 (current_lock_owner): Parse contents more carefully, to help avoid
1430 confusing a regular-file lock with some other application's use
1431 of the file. Check for lock file contents being too long, or
1432 not parsing correctly.
1433 (current_lock_owner, lock_file):
1434 Allow foreign pid and boot times that exceed the local range.
1435 (current_lock_owner, lock_if_free, lock_file):
1436 Simplify allocation of lock file contents.
1437 * w32.c (sys_rename_replace): New function, containing most of
1438 the contents of the old sys_rename.
1439 (sys_rename): Use it.
1440 (fchmod): New dummy function.
1441 * w32.h (sys_rename_replace, fchmod): New decls.
1443 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1445 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1446 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1447 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1448 <dmantipov@yandex.ru>.
1450 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1452 * composite.c (get_composition_id, fill_gstring_header):
1453 Use make_uninit_vector where appropriate.
1454 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1455 * xselect.c (clean_local_selection_data): Likewise.
1457 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1459 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1460 * image.c (imagemagick_load_image): Calculate height and width
1461 after flattening the image, not before.
1463 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1465 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1466 * ftfont.c (ftfont_shape_by_flt): Likewise.
1467 * w32uniscribe.c (uniscribe_shape): Likewise.
1469 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1471 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1472 The old approach, which fell back on DIR/.#FILE.0 through
1473 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1474 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1475 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1476 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1477 because the locking mechanism was never reliable in that case).
1478 This patch fixes this and other bugs discovered by a code
1479 inspection that was prompted by
1480 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1481 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1482 to avoid interoperability problems between the MS-Windows and
1483 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1484 instances of Emacs now ignore each others' locks.
1485 * filelock.c (defined_WINDOWSNT): New constant.
1486 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1487 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1488 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1489 regular files on MS-Windows hosts.
1490 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1491 Use SAFE_ALLOCA to avoid problems with long file names.
1492 (MAX_LFINFO): Now a local constant, not a global macro.
1493 (IS_LOCK_FILE): Remove.
1494 (lock_file_1): Don't inspect errno if symlink call succeeds;
1495 that's not portable.
1496 (lock_file): Document that this function can return if lock
1498 (lock_file): Don't access freed storage.
1500 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1502 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1504 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1506 * textprop.c: Use bool for booleans.
1507 (validate_interval_range, Fadd_text_properties)
1508 (Fremove_text_properties): Prefer bool to int when either works.
1510 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1512 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1513 If the interval tree changes as a side effect of calling
1514 modify_region, re-do processing starting from the call to
1515 validate_interval_range. (Bug#13743)
1517 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1519 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1522 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1524 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1525 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1526 access to the lock file until it is written and closed.
1529 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1531 * callint.c (Qcall_interactively):
1532 * macros.c (Qexecute_kbd_macro):
1535 2013-02-26 Bastien Guerry <bzg@gnu.org>
1537 * window.c (Frecenter): Tiny docstring enhancement.
1539 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1541 Minor textprop integer cleanup.
1542 * intervals.h, textprop.c (add_text_properties_from_list):
1543 Return void, not int, since nobody uses the return value.
1544 * textprop.c (validate_plist, add_properties, remove_properties)
1545 (Fadd_text_properties):
1546 Don't assume list length fits in int.
1547 (interval_has_all_properties, interval_has_some_properties)
1548 (interval_has_some_properties_list, add_properties, remove_properties)
1549 (Fadd_text_properties, Fremove_text_properties)
1550 (Fremove_list_of_text_properties, text_property_stickiness):
1551 Use bool for booleans.
1552 (Fadd_text_properties, Fremove_text_properties):
1553 (Fremove_list_of_text_properties):
1554 Reindent do-while as per GNU style.
1556 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1558 Implement CLASH_DETECTION for MS-Windows.
1560 * filelock.c [WINDOWSNT]: Include w32.h.
1561 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1562 function of that name. Up-case the macro arguments.
1563 (IS_LOCK_FILE): New macro.
1564 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1565 (create_lock_file): New function, with body extracted from
1567 [WINDOWSNT]: Implement lock files by writing a regular file with
1568 the lock information as its contents.
1569 (read_lock_data): New function, on Posix platforms just calls
1571 [WINDOWSNT]: Read the lock info from the file.
1572 (current_lock_owner): Call read_lock_data instead of calling
1573 emacs_readlinkat directly.
1574 (lock_file) [WINDOWSNT]: Run the file name through
1577 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1578 just check if the process by that PID exists.
1580 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1581 also present, as doing so will fail to error out if the file
1584 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1586 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1587 (Fremove_list_of_text_properties): Skip all of the intervals in
1588 the region between START and END that already have resp. don't
1589 have the requested properties, not just the first one.
1590 Add assertions that the loop afterwards always modifies the
1591 properties. (Bug#13743)
1593 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1595 * callint.c (Fcall_interactively): Use the right lexical environment
1596 for `interactive' specs (bug#13811).
1597 * eval.c (Feval): Accept a lexical environment.
1599 2013-02-25 Paul Eggert <eggert@cs.ucla.edu>
1601 Simplify data_start configuration (Bug#13783).
1602 This is a followon simplification to the fix for Bug#13650.
1603 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
1604 (START_FILES): Remove. All uses removed.
1605 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
1606 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
1607 (buildobj.h): Use it.
1608 ($(ALLOBJS)): Depend on globals.h.
1609 (temacs$(EXEEXT)): Use $(ALLOBJS).
1610 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1611 * deps.mk (vm-limit.o):
1612 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
1613 Do not depend on mem-limits.h.
1614 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
1615 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)

1620 (make_hdr): Use DATA_START instead of start_of_data.
1621 * vm-limit.c: Move most of mem-limits.h's contents here.
1622 (data_start): New decl. It's OK if this is approximate,
1623 so simplify-away some unnecessary exactness.
1624 (POINTER): Remove; all uses removed.
1625 (data_space_start): Now char *, to avoid casts.
1626 (exceeds_lisp_ptr): New function, replacing the old
1627 EXCEEDS_LISP_PTR macro. All uses changed.
1628 (check_memory_limits): Simplify and remove casts.
1629 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
1630 (memory_warnings): Use data_start instead of start_of_data.
1632 2013-02-24 Andreas Schwab <schwab@linux-m68k.org>
1634 * xdisp.c (set_message): Only check for debug-on-message if STRING
1635 is a string. (Bug#13797)
1637 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>
1639 Fix regression introduced by July 10 filelock.c patch.
1640 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
1641 2012-07-10 patch to this file. Reported by Eli Zaretskii in
1642 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
1643 and diagnosed by Andreas Schwab in
1644 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
1646 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1648 Assume C89 or better.
1649 * ralloc.c (SIZE, POINTER, NIL):
1650 * vm-limit.c (POINTER):
1651 Remove, replacing all uses with C89 equivalents. These old
1652 symbols were present only for porting to pre-C89 platforms.
1654 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1656 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1657 This avoids warning messages reported as part of Bug#13546.
1659 2013-02-21 Ken Brown <kbrown@cornell.edu>
1661 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.

1672 2013-02-19 Daniel Colascione <dancol@dancol.org>
1674 * sheap.c (report_sheap_usage): Use message, not message1, so
1675 that we don't try to create a buffer while we're in the middle
1676 of dumping Emacs. Explain why.
1678 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1680 * search.c (find_newline): Return byte position in bytepos.
1682 (find_next_newline_no_quit, find_before_next_newline):
1683 Add bytepos argument.
1684 * lisp.h (find_newline, find_next_newline_no_quit)

1690 (get_visually_first_element, move_it_vertically_backward):
1691 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
1693 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1695 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1696 resources were not orderly released.
1698 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1700 * xdisp.c (x_draw_vertical_border): For a window that is neither
1701 the leftmost nor the rightmost, redraw both the left and the right
1702 vertical borders. (Bug#13723)

1724 * w32.c (sys_chown): Remove unused function.
1726 * w32term.c <input_signal_count>: Declare 'volatile'
1727 unconditionally. (Bug#9066)
1729 * w32.c (set_errno): Reset h_errno and don't set it to any other
1730 value. Set errno instead.
1731 (check_errno): Reset h_errno.
1732 (sys_socket, socket_to_fd, sys_bind, sys_connect)
1733 (sys_gethostname, sys_getservbyname, sys_getpeername)
1734 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1735 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set

1745 * keyboard.c (read_char): Fix calculation of auto-save time out
1746 when auto-save-timeout is less than 4. (Bug#13720)
1748 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1749 time. Improve diagnostics in DebPrint. (Bug#13546)

1753 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1754 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
1755 make sure errno is set to an appropriate value. (Bug#13546)
1756 (socket_to_fd): Add assertion against indexing fd_info[] with a
1757 value that is out of bounds.
1758 (sys_accept): If fd is negative, do not set up the child_process
1759 structure for reading.
1761 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1763 * composite.c (fill_gstring_header): Remove useless prototype.

1775 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1777 Fix AIX port (Bug#13650).
1778 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1779 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1780 was #undeffed earlier, so it cannot be used as a macro here.
1781 Use the constant and not the macro.
1783 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1785 * w32proc.c (new_child): If no vacant slots are found in
1786 child_procs[], make another pass looking for slots whose process
1787 has exited or died. (Bug#13546)
1789 * w32.c (sys_pipe): When failing due to file descriptors above
1790 MAXDESC, set errno to EMFILE.
1791 (_sys_read_ahead): Update cp->status when failing to read serial
1792 communications input, so that the status doesn't stay at
1793 STATUS_READ_IN_PROGRESS. (Bug#13546)
1795 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1797 * gtkutil.c (tb_size_cb): New function.
1798 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1800 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1802 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1805 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1807 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1809 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
1811 * font.c (font_range): Add pos_byte argument. Adjust comment
1812 and break long line.
1813 * font.h (font_range): Adjust prototype.
1814 * composite.c (autocmp_chars): Pass byte position to font_range.
1815 Break long line. Remove useless prototype and format comment.
1817 2013-02-13 Glenn Morris <rgm@gnu.org>
1819 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1821 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1823 Improve AIX port some more (Bug#13650).
1824 With this, it should be as good as it was in 23.3, though it's
1825 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1826 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1827 * unexaix.c (start_of_text): Remove.
1828 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1829 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1830 (orig_load_scnptr, orig_data_scnptr):
1831 Now off_t, not long, since they are file offsets.
1832 (make_hdr): Use _data, not start_of_data ().
1833 This is the key part of the fix.
1834 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1835 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1837 * pre-crt0.c (data_start): Initialize to 1.
1838 This ports to compilers that optimize the external declaration
1839 'int x = 0;' as if it were 'int x;' to shrink the executable.
1841 Improve AIX port (Bug#13650).
1842 This doesn't fix the bug, but it makes progress: Emacs builds now.
1843 * unexaix.c: Include inttypes.h, stdarg.h.
1844 (report_error, report_error_1): Mark as _Noreturn.
1845 (report_error): Don't report the wrong errno.
1846 (report_error_1): Now varargs. All callers changed.
1847 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1848 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1849 (write_ptr): Use %p to print address rather than %lx and a cast
1850 to unsigned long. Grow buffer a bit, to be safer.
1852 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1854 * bidi.c (bidi_resolve_neutral): After finding the next
1855 non-neutral character, accept NEUTRAL_ON type as well, because
1856 directional control characters, such as LRE and RLE, have their
1857 type converted to that by bidi_resolve_weak. This avoids aborts
1858 when LRE/RLE follows a run of neutrals.
1859 (bidi_move_to_visually_next): Assert that return value of
1860 bidi_peek_at_next_level is non-negative. Negative values will
1863 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1865 Minor getenv-related fixes.
1866 * callproc.c (Fcall_process_region) [!DOS_NT]:
1867 Avoid unnecessary duplicate call to getenv.
1868 * callproc.c (init_callproc):
1869 * dispnew.c (init_display):
1870 * sysdep.c (sys_subshell):
1871 Omit unnecessary cast of getenv or egetenv.
1873 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1875 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1876 Update dependencies.
1878 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1880 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1882 (display_line): Set w->region_showing to the value of
1883 it->region_beg_charpos, not to -1. This fixes redisplay
1884 optimization when cursor is moved up after M->. (Bug#13623)
1886 (try_scrolling): Scroll text up more if point is too close to ZV
1887 and inside the scroll margin. This makes sure point is moved
1888 outside the scroll margin in these cases.
1890 * window.h (struct window): region_showing can no longer be
1893 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>

1898 * search.c (find_newline, scan_newline):
1899 * xdisp.c (pos_visible_p, display_count_lines):
1900 Use memchr and memrchr rather than scanning byte-by-byte.

1906 (read_key_sequence): Remove unused locals.
1908 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1910 Clean up read_key_sequence a bit; reread active keymaps after first event.

1915 (active_maps): New function.
1916 (test_undefined): Also return true for nil bindings.
1917 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1918 a single (composed) keymap. Remember `first_event' to choose the right
1919 set of active keymaps. Recompute the set of keymaps after receiving
1920 the first event. Remove GOBBLE_FIRST_EVENT.
1921 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1922 * keyboard.h (read_char): Update declaration.
1923 * lread.c (read_filtered_event): Adjust call to read_char.
1925 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1927 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1928 Don't use the limitation on backwards movement when lines are truncated
1929 in the window. (Bug#13675)
1931 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1933 * marker.c (set_marker_internal): If desired position is passed
1934 as a marker, avoid call to buf_charpos_to_bytepos.
1935 * window.c (Fset_window_point): Omit redundant type checking.
1936 (Fset_window_start): Likewise. Format comment.
1937 (window_scroll_pixel_based): Use set_marker_restricted_both
1938 with character and byte positions obtained from an iterator.
1939 (Fset_window_configuration): Use set_marker_restricted_both.
1940 * xdisp.c (message_dolog): Likewise.
1942 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1944 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1945 When text lines are longer than window's screen lines, don't move back
1946 too far. This speeds up some redisplay operations. (Bug#13675)
1948 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1950 * syntax.c (scan_sexps_forward): Fix byte position calculation

1962 (sxhash_float): Return EMACS_UINT, for consistency with the other
1964 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1965 non-static inline function and therefore can't use static vars.
1966 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1967 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1968 with the other hash functions.
1970 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1972 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1973 XXXXXX part of the temporary file pattern is not downcased even
1974 when w32-downcase-file-names is non-nil. (Bug#13661)
1976 * xdisp.c (decode_mode_spec): Remove handling of %t.
1978 * msdos.c (careadlinkatcwd): Remove.
1980 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1982 * lread.c (skip_dyn_bytes): New function (bug#12598).

2018 argument is known to be a vector.
2019 * fns.c (Flocale_info): Likewise for ASET.
2020 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
2021 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
2023 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
2025 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
2028 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
2029 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and

2032 * nsterm.m (NEW_STYLE_FS): Remove.
2033 (ns_last_use_native_fullscreen): New variable.
2034 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
2035 (x_set_window_size): Do not take title bar and tool bar into account
2036 if isFullscreen returns YES.
2037 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
2038 (check_native_fs): New function.
2039 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.

2042 and tool bar if isFullscreen returns NO.
2043 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
2044 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
2045 with HAVE_NATIVE_FS.

2056 (syms_of_nsterm): Add ns-use-native-fullscreen.
2058 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
2060 * fileio.c (Qchoose_write_coding_system): Now static.
2062 2013-02-04 Eli Zaretskii <eliz@gnu.org>
2064 * xdisp.c (window_buffer_changed): region_showing can be negative,
2065 which still means region is being displayed.
2066 (redisplay_internal): Resurrect code that forced redisplay of the
2067 whole window when showing region and the mark has changed.
2068 Record the new mark position to allow redisplay optimizations.
2069 (display_line): If it->region_beg_charpos is non-zero, set the
2070 window's region_showing member to -1. (Bug#13623) (Bug#13626)
2072 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
2073 not bitfield of 1 bit.
2075 2013-02-03 Daniel Colascione <dancol@dancol.org>
2077 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
2078 daemon mode works on cygw32 when Emacs is installed and not just
2081 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2083 Avoid file time stamp bug on MS-Windows (Bug#13149).
2084 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2085 as FAT32 doesn't update time stamps when truncating them.
2086 Also, check that a file time stamp is not a multiple of 100 ns;
2087 this should catch all instances of the problem on MS-Windows,
2088 as its native file system resolution is 100 ns or worse, and
2089 checking for a non-multiple of 100 ns should impose only a small
2090 overhead on systems with ns resolution.
2092 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2094 Avoid encoding file names on MS-Windows when they need to be run
2095 through dostounix_filename.
2096 * w32.c (normalize_filename): Accept an additional argument
2097 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2098 downcase it even if w32-downcase-file-names is non-nil.
2099 (dostounix_filename): Accept an additional argument MULTIBYTE and
2100 pass it to normalize_filename.
2101 (emacs_root_dir): Adjust.
2103 * msdos.h (dostounix_filename): Adjust prototype.
2105 * w32.h (dostounix_filename): Adjust prototype.
2107 * msdos.c (dostounix_filename): Accept an additional argument and
2109 (init_environment): Adjust callers of dostounix_filename.
2111 * fileio.c (Ffile_name_directory, file_name_as_directory)
2112 (directory_file_name, Fexpand_file_name)
2113 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2115 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2117 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2118 variables, as egetenv is case-insensitive for DOS_NT.
2120 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2121 with an encoded file name.
2123 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2124 Adjust calls to dostounix_filename.
2126 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2128 * unexw32.c (unexec): Adjust call to dostounix_filename.
2130 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2132 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2135 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2138 * callproc.c (Fcall_process): Make sure program name in PATH and
2139 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2140 is passed to exec/spawnve, which fails unless the file-name
2143 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2144 even if w32-quote-process-args is nil.
2146 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2148 Fix timestamp bug when write-region appends nothing (Bug#13149).
2149 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2150 the file's time stamp doesn't change if Emacs happens to write nothing
2151 to the file, and on a buggy file system this could cause Emacs to
2152 incorrectly infer that the file system doesn't have the bug.
2153 Avoid this problem by inhibiting the inference in this case.
2155 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2157 * window.h (struct window): Convert base_line_number, base_line_pos
2158 and column_number_displayed members from Lisp_Object to ptrdiff_t.

2162 (make_window): Initialize column_number_displayed.
2163 * print.c (print_object): Follow the printed representation of
2164 frames and print window pointer to distinguish between windows.

2168 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2169 (try_scrolling, try_cursor_movement, redisplay_window)
2170 (try_window_reusing_current_matrix, try_window_id, display_line)
2171 (display_mode_lines, decode_mode_spec): Adjust users.
2172 * .gdbinit (pwinx): Do not print sequence_number.
2174 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2176 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2177 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2178 * dired.c: Include <fcntl.h>.
2179 (open_directory): New function, which uses open and fdopendir
2180 rather than opendir. DOS_NT platforms still use opendir, though.

2182 (file_attributes): New function, with most of the old Ffile_attributes.
2183 (directory_files_internal, Ffile_attributes): Use it.
2184 (file_attributes, file_name_completion_stat): First arg is now fd,
2185 not dir name. All uses changed. Use fstatat rather than lstat +
2187 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2188 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2189 (emacs_readlinkat): New function, with much of the old
2190 Ffile_symlink_p, but with an fd argument for speed.
2191 It uses readlinkat rather than careadlinkatcwd, so that it
2192 need not assume the working directory.
2193 (Ffile_symlink_p): Use it.
2194 * filelock.c (current_lock_owner): Use emacs_readlinkat
2195 rather than emacs_readlink.
2196 * lisp.h (emacs_readlinkat): New decl.
2197 (READLINK_BUFSIZE, emacs_readlink): Remove.
2198 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2199 (emacs_norealloc_allocator, emacs_readlink): Remove.
2200 This stuff is moved to fileio.c.
2201 * w32.c (fstatat, readlinkat): New functions.
2202 (careadlinkat): Don't check that fd == AT_FDCWD.
2203 (careadlinkatcwd): Remove; no longer needed.

2215 (sys_close): Zero out the flags for the file descriptor before
2216 closing it. (Bug#13546)
2218 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2219 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2220 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2223 * w32.c (w32_get_long_filename, init_environment, readlink):
2224 Support file names encoded in DBCS codepages.
2225 (readlink): Use the current file-name-coding-system, not the ANSI
2226 codepage, to decode and handle targets of symlinks.
2228 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2230 * w32.c (opendir): Now accepts a 'const char *'.
2232 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>

2237 (Vredisplay_preemption_period): Likewise.
2238 (update_frame, update_single_window, update_window, update_frame_1):
2239 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2240 used, following the 2012-06-22 change.
2242 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2244 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2246 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2248 * font.c (num_fonts): Remove the leftover from old
2249 debugging code. Adjust comment style here and there.
2250 * insdel.c (insert_1): Remove.
2251 * lisp.h (insert_1): Remove prototype.
2252 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2254 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2256 * w32.c (max_filename_mbslen): New function.
2257 (normalize_filename, readdir): Use it to detect locales where ANSI
2258 encoding of file names uses a double-byte character set (DBCS).
2259 If a DBCS encoding is used, advance by characters using
2260 CharNextExA, instead of incrementing a 'char *' pointer.
2261 Use _mbslwr instead of _strlwr. (Bug#13515)
2263 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2264 request of memory reservation to 1.7GB. (Bug#13065)

2274 Avoid redundant calls to strlen.
2276 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2278 Drop async_visible and async_iconified fields of struct frame.
2279 This is possible because async input is gone; for details, see
2280 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2281 * frame.h (struct frame): Remove async_visible and async_iconified
2282 members, convert garbaged to unsigned bitfield. Adjust comments.
2283 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2284 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2285 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2286 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2287 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2289 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2290 properly. Likewise for obscured.

2300 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2302 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2304 * xdisp.c (message2, message2_nolog): Remove functions.
2305 (message3, message3_nolog): Extract nbytes and multibyteness directly
2306 from the string. Change all callers.
2307 (message3_nolog): Don't set message_enable_multibyte since set_message
2308 will reset it anyway.
2309 (message1, message1_nolog): Use message3.
2310 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2311 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2312 (set_message): Drop all but the second arg, which has to be a string.
2313 (set_message_1): Simplify now that we know that a1 is NULL and the
2314 second arg is a string.
2315 * frame.h (struct frame): Remove `message_buf' field.
2316 Use glyphs_initialized_p instead.
2317 (FRAME_MESSAGE_BUF): Remove macro.

2321 * keyboard.c (read_char_minibuf_menu_text)
2322 (read_char_minibuf_menu_width): Remove vars.
2323 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2324 to correctly handle multibyte strings.
2325 * frame.c (delete_frame): Don't free message_buf any more.
2326 * editfns.c (message_text, message_length): Remove vars.
2327 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2328 * fileio.c (auto_save_error): Use message3 instead of message2.
2329 * dispnew.c (adjust_frame_message_buffer): Remove function.
2331 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2333 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2334 real estate used for the tool bar and the menu bar.
2336 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2338 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2339 hidden buffer is prepared to modification (Bug#13164).
2341 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2343 * window.h (struct window): Change window_end_valid member from
2344 Lisp_Object to a bitfield. Adjust comments.
2345 (wset_window_end_valid): Remove.
2346 * window.c (adjust_window_count): Clear window_end_valid.
2347 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2348 (Fwindow_line_height, set_window_buffer, Frecenter)
2349 (Fsplit_window_internal, Fdelete_other_windows_internal)
2350 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2351 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2352 * xdisp.c (check_window_end, reconsider_clip_changes)
2353 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2354 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2355 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2357 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2359 * xdisp.c (mark_window_display_accurate): Simplify the loop
2360 assuming that the only one of vchild, hchild or buffer window
2361 slots is non-nil. Call mark_window_display_accurate_1 for
2362 the leaf windows only.
2363 (mark_window_display_accurate_1): Always assume leaf window.
2366 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2368 * emacs.c (Qkill_emacs_hook): Now static.
2370 * fileio.c (Finsert_file_contents): Simplify.
2371 Remove unnecessary assignments and tests.
2373 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2375 * w32.c (acl_set_file): Don't test for errors unless
2376 set_file_security returns FALSE. Avoids spurious errors when
2379 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2381 * fileio.c (Finsert_file_contents): Revert code introduced at
2382 2013-01-18 in favor of the simpler and generally better fix.
2383 Save stack space by removing 'buffer' and reusing 'read_buf'
2386 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2388 * lisp.h (eabs): Define unconditionally (Bug#13419).
2389 The old "#if !defined (eabs)" was an unnecessary revenant of back
2390 when this macro was called "abs". Document 'eabs' better.
2392 2013-01-19 Glenn Morris <rgm@gnu.org>
2394 * fns.c (Frandom): Doc fix.
2396 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2398 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2399 segfault when there are lots of overlays.
2401 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2402 when there are lots of overlays.
2403 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2404 for the details and a way to reproduce.
2406 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2408 * fileio.c: Use O_APPEND to append.
2409 This corresponds better to the natural interpretation of "append",
2410 and avoids the need to open the output file twice, or to invoke
2411 lseek when APPEND is neither nil nor a number.
2412 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2413 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2414 file possibly twice, and lseeking to its end; this avoids the
2415 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2416 at the same time: the combination is never needed and apparently
2417 it doesn't work with DOS_NT.
2419 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2420 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2422 Allow floating-point file offsets.
2423 Problem reported by Vitalie Spinu in
2424 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2425 * fileio.c (emacs_lseek): Remove.
2426 (file_offset): New function.
2427 (Finsert_file_contents, Fwrite_region): Use it.
2429 2013-01-19 Chong Yidong <cyd@gnu.org>
2431 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2432 aborting on Fsignal (Bug#13289).
2434 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2436 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2437 set_file_security as failure due to insufficient privileges.
2438 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2439 (fstat): Return owner and group like 'stat' and 'lstat' do.
2441 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2443 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2444 The bug was observed on Ubuntu operating inside a virtual machine,
2445 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2446 The workaround introduces a race condition on non-buggy hosts,
2447 but it's an unlikely race and anyway there's a nearly identical
2448 nearby race that can't be fixed.
2449 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2451 (Fwrite_region): Test for file system time stamp bug.
2452 (init_fileio): New function.
2453 * lisp.h (init_fileio): Declare it.
2454 * emacs.c (main): Call it.
2456 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2457 and make it more consistent with other stat-failure diagnostics.
2459 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2461 Fix crash when inserting data from non-regular files.
2462 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2463 for the error description produced by valgrind.
2464 * fileio.c (read_non_regular): Rename to read_contents.
2465 Free Lisp_Save_Value object used to pass parameters.
2466 (read_non_regular_quit): Rename to read_contents_quit.
2467 (Finsert_file_contents): Redesign internal file reading loop to adjust
2468 gap and end positions after each read and so help make_gap to work
2469 properly. Do not signal an I/O error too early and so do not leave
2470 not yet decoded characters in a buffer, which was the reason of
2471 redisplay crash. Use list2 to build return value. Adjust comments.
2473 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2475 Close a race when statting and reading files (Bug#13149).
2476 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2477 This avoids a race if the file is renamed between stat and open.
2478 This race is not the problem originally noted in Bug#13149;
2479 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2481 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2488 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2489 * alloc.c (format_save_value): Rename to make_save_value.
2490 (make_save_pointer): New function.
2491 (record_xmalloc): Use make_save_pointer.
2492 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2493 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2494 Change users of make_save_value to make_save_pointer.
2495 Likewise for format_save_value and make_save_value.

2506 * alloc.c (free_save_value): Now static.
2508 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2510 * keymap.c (map_keymap_internal): Use format_save_value.
2511 (map_keymap_char_table_item): Adjust accordingly.
2512 * fileio.c (non_regular_fd, non_regular_inserted)
2513 (non_regular_nbytes): Remove.
2514 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2515 Use format_save_value to pass parameters to read_non_regular.
2516 (read_non_regular): Use XSAVE_ macros to extract parameters.
2518 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2520 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2522 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2524 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2525 extraction from any Lisp_Save_Value slot. Add type checking.
2526 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2527 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2528 * xselect.c: All users changed.
2530 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

2540 * editfns.c (save_excursion_save): Use format_save_value.
2541 (save_excursion_restore): Use XSAVE_OBJECT.
2543 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2545 Avoid needless casts with XSAVE_POINTER.
2546 * alloc.c (mark_object) [GC_MARK_STACK]:
2547 * dired.c (directory_files_internal_unwind):
2548 * fileio.c (do_auto_save_unwind):
2549 * gtkutil.c (pop_down_dialog):
2550 * keymap.c (map_keymap_char_table_item):
2551 * lread.c (load_unwind):
2552 * nsmenu.m (pop_down_menu):
2553 * print.c (print_object) [GC_MARK_STACK]:
2554 * xfns.c (clean_up_file_dialog):
2555 * xmenu.c (cleanup_widget_value_tree):
2556 Omit casts between XSAVE_POINTER and a pointer type.
2558 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2560 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
2561 * eval.c (eval_sub): Protect `form' from being GCed before its
2562 car and cdr becomes protected with the backtrace entry.
2564 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2566 Make Lisp_Save_Value more versatile storage for up to four objects.
2567 * lisp.h (toplevel): Enumeration to describe types of saved objects.
2568 (struct Lisp_Save_Value): New layout. Adjust comments.
2569 (XSAVE_POINTER): New macro.
2570 (XSAVE_INTEGER): Likewise.
2571 (allocate_misc): Add prototype.
2572 (free_misc): Likewise.

2576 (free_save_value): Likewise.
2577 (mark_object): Likewise.
2578 * editfns.c (save_excursion_save): Pack everything within
2579 Lisp_Save_Value and so avoid xmalloc.
2580 (save_excursion_restore): Adjust to match new layout. Use free_misc
2581 because we do not allocate extra memory any more. Add eassert.
2582 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2583 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
2584 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
2585 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

2591 (nsfont_draw): Remove disabling of LCD smoothing.
2592 (ns_glyph_metrics): Add LCD_SMOOTHING_MARGIN to bearings to fix
2593 Bug#11484 with LCD smoothing on.
2595 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
2597 Fix SIGDANGER handlers, for AIX (Bug#13408).
2598 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
2599 Move handlers here from emacs.c; they were out of place.
2601 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
2603 * xterm.c (syms_of_xterm): Adjust documentation for
2604 scroll-bar-adjust-thumb-portion.
2606 2012-12-31 Adam Sjøgren <asjo@koldfront.dk> (tiny change)

2619 (doCommandBySelector:): Set processingCompose to NO.
2621 * nsfont.m (ns_findfonts): Add block/unblock_input calls.
2622 Remove check for fkeys count > zero, block/unblock fixes the real bug.
2623 (nsfont_list_family): Add block/unblock_input calls.
2624 (nsfont_open): Move block_input earlier. Add unblock_input before early
2626 (nsfont_draw): Add block/unblock_input calls.
2628 2013-01-12 Dmitry Antipov <dmantipov@yandex.ru>
2630 * indent.c (Fvertical_motion): Remove now-incorrect GCPROs
2631 for old_charpos and old_bytepos.
2633 2013-01-12 Paul Eggert <eggert@cs.ucla.edu>
2635 Fix bug with set-time-zone-rule and LOCALTIME_CACHE (Bug#13415).
2636 * editfns.c (set_time_zone_rule) [LOCALTIME_CACHE]:
2637 Clear tzvalbuf_in_environ if this workaround is in effect.
2638 Problem and fix reported by Kazuhiro Ito.
2640 2013-01-11 Aaron S. Hawley <Aaron.Hawley@vtinfo.com>

2649 string cross-reference(s).
2651 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2653 Avoid unnecessary byte position calculation for the gap movement.
2654 Since all users of move_gap do CHAR_TO_BYTE for other purposes
2655 anyway, all of them should use move_gap_both instead.
2656 * lisp.h (move_gap): Remove prototype.
2657 * insdel.c (move_gap): Remove.
2658 (move_gap_both): Add eassert.

2665 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
2667 * term.c (init_tty): Use them instead of rolling our own code.
2668 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2669 switches from 'signal' to 'pthread_sigmask', which is safer in
2670 multithreaded applications.
2671 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2672 which has already arranged for that.
2673 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2674 This is the main part of the bug fix.

2681 2013-01-10 Dmitry Antipov <dmantipov@yandex.ru>
2683 Omit buffer_slot_type_mismatch and use generic predicates to enforce
2684 the type of per-buffer values where appropriate.
2685 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
2686 predicate, which is how it's really used now. Adjust comment.
2687 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2688 * buffer.c (buffer_slot_type_mismatch): Remove.
2689 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

2693 left-margin-width, right-margin-width, left-fringe-width,
2694 right-fringe-width, scroll-bar-width and buffer-display-count.
2695 Use Qstringp for default-directory, buffer-file-name,
2696 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2697 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
2699 * data.c (store_symval_forwarding): Adjust to call the predicate.
2701 2013-01-09 Juanma Barranquero <lekktu@gmail.com>
2703 * w32.c (get_name_and_id, acl_set_file):
2704 * w32term.c (w32fullscreen_hook): Remove unused local variables.

2714 * insdel.c (make_gap_larger): Use GAP_BYTES_DFL. Adjust comment.
2715 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
2716 (make_gap_1): New function to adjust the gap of any buffer.
2717 * coding.c (coding_alloc_by_making_gap): Use it.
2718 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
2719 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.
2721 2013-01-08 Juri Linkov <juri@jurta.org>
2723 * xfaces.c (tty_supports_face_attributes_p): Return 0 for the case
2724 of (supports :underline (:style wave)). (Bug#13000)
2726 2013-01-08 Aaron S. Hawley <aaron.s.hawley@gmail.com>
2728 * undo.c (Fprimitive_undo): Move to simple.el.

2740 (echo_char): Use it.
2741 (read_key_sequence): When echoing mock input, ensure that the
2742 trailing dash is properly added.
2744 2013-01-05 Eli Zaretskii <eliz@gnu.org>
2746 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
2747 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2748 digits for buffer positions, before misalignment starts.
2749 Display "0" for integer "object" field.
2750 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2751 Display the newline glyph more unambiguously.
2753 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2755 * nsterm.m (ns_draw_underwave):
2756 * w32term.c (w32_draw_underwave):
2757 * xterm.c (x_draw_underwave): Make underwave look more triangular

2761 * w32term.c (x_draw_glyph_string):
2762 * xterm.c (x_draw_glyph_string): Don't use previous underline
2763 thickness and position if previous underline type is underwave.

2784 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2785 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2787 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2789 * w32.c (unsetenv): Set up the string passed to _putenv
2791 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2792 for the bug this caused.
2794 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2796 * coding.c (Qmac): Now static.
2798 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2800 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2801 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
2802 handlebox_widget. Set toolbar_in_hbox to false/true, set
2803 toolbar_is_packed to true.
2804 (xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
2805 (update_frame_tool_bar): Check toolbar_is_packed for packing.
2806 Show all on TOOLBAR_TOP_WIDGET.
2807 (free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
2808 by TOOLBAR_TOP_WIDGET.
2809 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2810 Check toolbar_is_packed.
2811 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2812 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2813 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2815 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2816 (xg_update_menubar): Update title only if
2817 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2818 (xg_update_submenu): Skip tearoff only if
2819 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2820 (xg_initialize): Initialize xg_detached_menus only if
2821 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2823 * xterm.h (struct x_output): Surround handlebox_widget with
2824 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2825 toolbar_in_hbox is bool.
2827 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2829 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2830 (LIBS_GNUSTEP): Define.
2831 (LIBES): Add $(LIBS_GNUSTEP).
2832 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
2834 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2836 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2837 continuation glyph on a TTY with an indication of an empty line.
2840 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2842 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2843 file's SELinux context or ACLs successfully set, nil otherwise.
2845 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
2847 * w32proc.c (reader_thread): Avoid passing NULL handles to
2848 SetEvent and WaitForSingleObject.
2850 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2852 Port EXTERNALLY_VISIBLE to Clang 3.2.
2853 * conf_post.h (__has_attribute): New macro.
2854 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2856 2012-12-27 Glenn Morris <rgm@gnu.org>
2858 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2859 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2861 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2863 * fileio.c (file_name_as_directory, directory_file_name):
2864 Accept an additional argument MULTIBYTE to indicate whether the input C
2865 came from a multibyte or a unibyte Lisp string; all callers
2866 adjusted. Don't assume the input string is always multibyte.
2868 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2869 don't ENCODE_FILE them, and return a unibyte string if the input
2871 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2872 don't assume the input strings will always be multibyte. If the
2873 input strings are multibyte, decode strings obtained from C
2876 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2878 * lisp.h (toplevel): Add two notices to the comment about
2879 defining a new Lisp data type.
2880 * print.c (print_object): If Lisp_Save_Value object's pointer
2881 is the address of a memory area containing Lisp_Objects, try
2883 * alloc.c (valid_lisp_object_p): Adjust comment.
2885 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2887 * keyboard.c (record_asynch_buffer_change): Initialize an event
2888 only if it's really needed.
2889 * frame.h (enum output_method): Remove output_mac member since
2890 it's a leftover from the deleted code.
2891 * frame.c (Fframep): Adjust user here ...
2892 * terminal.c (Fterminal_live_p): ... and here.
2893 * coding.c (Qmac): Now here because it's only used to denote
2894 end-of-line encoding type.
2895 (syms_of_coding): DEFSYM it.
2896 * frame.h (Qmac): Remove duplicated declaration.
2898 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2900 * window.c (select_window_1): Now static, since it's used only here.
2902 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2904 * window.c (window_body_cols): Subtract display margins from the
2905 window body width on TTYs as well. See
2906 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2907 for the original report.
2909 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2911 * xdisp.c (redisplay_window): Remove inner local variable
2912 because the outer shadowed one has the same meaning.
2913 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2915 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2916 (xg_create_tool_bar): Adjust users.
2918 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2920 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2921 * buffer.c (Fget_buffer_create): Use it to set compact field of
2922 struct buffer_text to avoid accessing an uninitialized value
2923 when compact_buffer is called for the first time.
2924 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2925 (Fset_buffer_modified_p): Use buffer_window_count to check
2926 whether the buffer is displayed in some window.
2927 * xdisp.c (message_dolog): Likewise.
2929 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2931 * w32.c (acl_set_file): If setting the file security descriptor
2932 fails, and the new DACL is identical to the existing one, silently
2933 return success. This fixes problems for users backing up their
2934 own files without having the necessary privileges for setting
2935 security descriptors.
2937 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2939 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2940 after WaitForSingleObject returns normally. This expedites reader
2941 thread shutdown when delete_child triggers it.
2942 (reap_subprocess): More accurate commentary for why we call
2943 delete_child only when cp->fd is negative.
2945 * w32.c (sys_close): Do not call delete_child on a subprocess
2946 whose handle is not yet closed. Instead, set its file descriptor
2947 to a negative value, so that reap_subprocess will call
2948 delete_child on that subprocess when its SIGCHLD arrives.
2949 This avoids closing handles used for communications between sys_select
2950 and reader_thread, which doesn't give sys_select a chance to
2951 notice that the process exited and invoke the SIGCHLD handler for
2954 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2956 * nsfns.m (Fns_do_applescript): Run event loop until script has
2957 been executed (Bug#12969).
2958 (ns_run_ascript): Chech as_script for nil, set to nil after
2961 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2963 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2965 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2967 * w32term.c (w32fullscreen_hook): New function.
2968 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2970 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2972 * fileio.c (Finsert_file_contents): Doc fix.
2974 * w32proc.c (new_child, delete_child, find_child_pid): For a
2975 subprocess, consider its slot being in use as long as its process
2976 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2977 slot when a new process is started immediately after killing
2978 another one, without waiting enough time for the first process to
2979 be reaped and resources allocated for it be orderly freed.
2981 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2983 2012-12-21 Chong Yidong <cyd@gnu.org>
2985 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2987 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2989 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2991 * w32.c (get_name_and_id): Always pass NULL as the first argument
2992 of lookup_account_sid. Avoids crashes with UNC file names that
2993 refer to DFS domains, not to specific machine names. (Bug#12621)
2994 Remove now unused argument FNAME; all callers changed.
2995 (get_file_owner_and_group): Remove now unused argument FNAME; all
2998 2012-12-21 Chong Yidong <cyd@gnu.org>
3000 * editfns.c (Finsert_char): Since read-char-by-name now signals an
3001 error for invalid chars, don't check for a nil return value.
3003 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3005 Avoid calls to CHAR_TO_BYTE if byte position is known.
3006 * editfns.c (make_buffer_string_both): Use move_gap_both.
3007 (Fbuffer_string): Use make_buffer_string_both.
3008 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
3010 (buf_bytepos_to_charpos): Likewise.
3011 (charpos_to_bytepos): Remove.
3012 * fileio.c (Finsert_file_contents): Use move_gap_both.
3013 * search.c (Freplace_match): Likewise.
3014 * process.c (process_send_region): Likewise. Use convenient
3015 names for byte positions.
3016 * lisp.h (charpos_to_bytepos): Remove prototype.
3017 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
3018 * insdel.c (move_gap): Likewise.
3020 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
3022 * xdisp.c (redisplay_internal): Remove now-unused local.
3024 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
3026 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
3027 (redisplay_internal): Don't bother selecting the frame to get the
3028 proper value of frame-local variables (bug#13225).
3030 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
3032 * textprop.c (set_text_properties_1): Do not allow NULL interval.
3033 Rename 4th argument since it may be buffer or string. Adjust comment.
3034 * intervals.c (graft_intervals_info_buffer): Find an interval here.
3036 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
3038 * coding.c (Fdetect_coding_region): Do not check start and end with
3039 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
3040 (code_convert_region): Likewise.
3042 2012-12-18 Eli Zaretskii <eliz@gnu.org>
3044 * w32.c (acl_get_file, acl_set_file): Run the file name through
3045 map_w32_filename, and resolve any symlinks in the file name, like
3047 (acl_set_file): Call revert_to_self, if any privileges were
3050 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
3052 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
3053 ($(BLD)/w32.$(O)): Update dependencies.
3055 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
3057 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
3058 propagate redisplay's scrolling (if any) to the right window.
3059 (redisplay_internal): Use ensure_selected_frame.
3060 (display_mode_lines): Complete last fix.
3061 * window.c (select_window_1): New func, extracted from select_window.
3062 (select_window): Use it.
3063 * window.h (select_window_1): Declare.
3065 2012-12-17 Eli Zaretskii <eliz@gnu.org>
3067 Emulate Posix ACL APIs on MS-Windows.
3068 * w32.c: Include sddl.h and sys/acl.h.
3069 (SDDL_REVISION_1): Define if not already defined.
3070 (g_b_init_get_security_descriptor_dacl)
3071 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
3072 (g_b_init_is_valid_security_descriptor)
3073 (g_b_init_set_file_security): New static flags.

3079 (IsValidSecurityDescriptor_Proc): New typedefs.
3080 (get_file_security, get_security_descriptor_owner)
3081 (get_security_descriptor_group): Set errno to ENOTSUP.

3084 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
3085 (acl_free, acl_get_file, acl_set_file): New functions.
3087 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
3089 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
3091 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3092 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3093 for some of that bug's symptoms can now cause Emacs to abort.
3094 Remove the workaround.
3095 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3096 The bug that caused SIGCHLD to get lost has been fixed, and the
3097 workaround for it can now cause Emacs to abort.
3099 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3101 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3102 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3103 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3105 2012-12-16 Romain Francoise <romain@orebokech.com>
3107 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3108 (Fcopy_file): Change last arg to `preserve_extended_attributes'
3109 and copy ACL entries of file in addition to SELinux context if set.
3110 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
3112 * Makefile.in (LIBACL_LIBS): New macro.
3115 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
3117 * fileio.c (internal_delete_file): Use bool for boolean.
3119 2012-12-15 Eli Zaretskii <eliz@gnu.org>
3121 Fix bug #13079 on MS-Windows with temp files not being deleted.

3124 (register_child): First argument is now pid_t.
3125 (record_infile, record_pending_deletion): New prototypes.
3127 * w32proc.c (new_child): Initialize input_file and
3128 pending_deletion members of the child.
3129 (delete_child): Delete the child's temporary input file, if any,
3130 that is pending deletion.
3131 (register_child): First argument is now pid_t.
3132 (record_infile, record_pending_deletion): New functions.
3133 (reap_subprocess): Fix a typo in DebPrint string.
3134 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3136 * fileio.c (internal_delete_file): Return an int again: non-zero
3137 if delete-file succeeds, zero otherwise.
3139 * lisp.h (internal_delete_file): Adjust prototype.
3141 * callproc.c (Fcall_process): Don't overwrite infile with result
3143 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3144 asynchronous subprocess, record the name of the input file name,
3146 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3147 delete the file, record it as pending deletion when the subprocess
3150 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3152 * editfns.c [HAVE_PWD_H]: Include grp.h.
3154 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3156 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3158 Fix permissions bugs with setgid directories etc. (Bug#13125)
3159 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3160 to mark it as a placeholder. The old value was often wrong.
3161 The only user of this attribute has been changed to use
3162 file-ownership-preserved-p instead, with its new group arg.
3163 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3165 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
3167 * xdisp.c (select_frame_for_redisplay, display_mode_lines):

3170 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3172 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3173 try to get accurate owner and group information from NT file
3174 security APIs. This is to make most callers of 'stat' and
3175 'lstat', which don't need that information, much faster.
3177 * dired.c (Ffile_attributes) [WINDOWSNT]:
3178 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3179 owner and group information from 'lstat'.
3181 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3183 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3184 as that confuses set-auto-coding, so insist on the head-read
3185 returning the full 1024 bytes. Let lseek compute the tail offset;
3186 less work for us. Do not ignore I/O errors when reading the tail.
3188 * xdisp.c: Minor style fixes.
3189 (init_iterator): Hoist assignment out of if-expression.
3190 (markpos_of_region): Callers now test for sign, not for -1.
3192 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
3194 Minor redisplay optimization when the region length is zero.
3195 * xdisp.c (markpos_of_region): New function.
3196 (init_iterator): Do not highlight the region of zero length.
3197 (redisplay_window): Check whether the region is of non-zero length.
3198 (try_cursor_movement): Allow if the region length is zero.
3199 (try_window_reusing_current_matrix, try_window_id): Likewise.
3201 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3203 * search.c (search_buffer): Check the inverse translations of each
3204 character in pattern when the buffer being searched is unibyte.
3207 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3209 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3210 files, fixing a regression from 24.2.
3211 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3213 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3215 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3216 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3217 Remove unnecessary S_ISLNK test, as (contra the comments) this
3218 function can't copy symlinks. Improve quality of error message
3219 when attempting to copy files that are neither regular files nor
3222 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
3224 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.
3225 * gtkutil.c (xg_set_toolkit_scroll_bar_thumb):
3226 * window.c (Frecenter):
3227 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
3228 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
3230 2012-12-12 Daniel Colascione <dancol@dancol.org>
3232 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
3233 the dumped Emacs is not a sparse file, greatly improving Cygwin
3234 "make bootstrap" performance.
3236 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
3238 * inotify.c (inotify_callback): Generate an Emacs event for every
3239 incoming inotify event.
3241 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3243 * xdisp.c (handle_face_prop): Fix logic of computing
3244 it->start_of_box_run_p.
3245 (append_space_for_newline): If the glyph row is R2L, reset the
3246 iterator's end_of_box_run_p flag before prepending the space glyph.
3247 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3248 iterator's start_of_box_run_p flag before prepending the stretch.
3249 (append_glyph, produce_image_glyph, append_composite_glyph)
3250 (append_stretch_glyph, append_glyphless_glyph): Reverse the

3452 * dbusbind.c (Fdbus_init_bus):
3454 * xterm.c (x_term_init):

3465 no longer needed here.

3468 (set_time_zone_rule): Maintain the TZ=value string separately.
3469 (syms_of_editfns): Don't initialize initial_tz;
3470 init_editfns now does it.

3490 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3491 Remove USG and vlimit methods; no longer used these days.
3492 Add #error catchall just in case.
3494 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3495 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3496 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

3518 This will cause a production Emacs to dump core instead of
3521 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3523 * frame.c (make_frame): Do not set window's buffer to t.
3524 * window.c (Fsplit_window_internal): Likewise. Previously it was
3525 used to indicate that the window is being set up. Now we use
3526 set_window_buffer for all new windows, so the condition in ...
3527 (Fset_window_buffer): ... is always true and can be removed.
3529 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3531 Convenient macro to check whether the buffer is hidden.
3532 * buffer.h (BUFFER_HIDDEN_P): New macro.

3539 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3540 if the child process is still running. Instead, exit the wait
3541 loop and return zero. (Bug#13086)
3543 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3545 * frame.h (x_char_width, x_char_height): Remove prototypes.

3556 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
3558 Fix a recently-introduced delete-process race condition.
3559 * callproc.c, process.h (record_kill_process):
3560 New function, containing part of the old call_process_kill.
3561 (call_process_kill): Use it.
3562 This does not change call_process_kill's behavior.
3563 * process.c (Fdelete_process): Use record_kill_process to fix a
3564 race condition that could cause Emacs to lose track of a child.
3566 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3568 Avoid code duplication between prev_frame and next_frame.
3569 * frame.c (candidate_frame): New function. Add comment.
3570 (prev_frame, next_frame): Use it. Adjust comment.
3572 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3574 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3575 fails, signal an error instead of continuing with an empty
3577 Encode expanded temp file pattern before passing it to mkstemp or
3580 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3581 Encode the file name before passing it to dostounix_filename, in
3582 case it will downcase it (under w32-downcase-file-names).
3585 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3587 Minor call-process cleanups.
3588 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3589 at the same time as other platforms, to simplify analysis.
3590 No need for fd0_volatile since we have synch_process_fd.
3591 Avoid needless emacs_close; arg is always negative.
3593 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3595 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous

3600 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3601 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer

3607 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3608 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3609 members to a bitfields.
3611 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3613 Don't let call-process be a zombie factory (Bug#12980).
3614 Fixing this bug required some cleanup of the signal-handling code.
3615 As a side effect, this change also fixes a longstanding rare race
3616 condition whereby Emacs could mistakenly kill unrelated processes,
3617 and it fixes a bug where a second C-g does not kill a recalcitrant
3618 synchronous process in GNU/Linux and similar platforms.
3619 The patch should also fix the last vestiges of Bug#9488,
3620 a bug which has mostly been fixed on the trunk by other changes.
3621 * callproc.c, process.h (synch_process_alive, synch_process_death)
3622 (synch_process_termsig, sync_process_retcode):
3623 Remove. All uses removed, to simplify analysis and so that
3624 less consing is done inside critical sections.
3625 * callproc.c (call_process_exited): Remove. All uses replaced
3626 with !synch_process_pid.
3627 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3628 These take the role of what used to be in unwind-protect arg.
3630 (block_child_signal, unblock_child_signal):
3631 New functions, to avoid races that could kill innocent-victim processes.
3632 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3633 (call_process_kill): Record killed processes as deleted, so that
3634 zombies do not clutter up the system. Do this inside a critical
3635 section, to avoid a race that would allow the clutter.
3636 (call_process_cleanup): Fix code so that the second C-g works again
3637 on common platforms such as GNU/Linux.
3638 (Fcall_process): Create the child process in a critical section,
3639 to fix a race condition. If creating an asynchronous process,
3640 record it as deleted so that zombies do not clutter up the system.
3641 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3642 light of these changes. Omit unnecessary call to emacs_close
3643 before failure, as the unwind-protect code does that.
3644 * callproc.c (call_process_cleanup):
3645 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3646 * process.c (record_deleted_pid): New function, containing
3647 code refactored out of Fdelete_process.
3648 (Fdelete_process): Use it.
3649 (process_status_retrieved): Remove. All callers changed to use
3650 child_status_change.
3651 (record_child_status_change): Remove, folding its contents into ...
3652 (handle_child_signal): ... this signal handler. Now, this
3653 function is purely a handler for SIGCHLD, and is not called after
3654 a synchronous waitpid returns; the synchronous code is moved to
3655 wait_for_termination. There is no need to worry about reaping
3656 more than one child now.
3657 * sysdep.c (get_child_status, child_status_changed): New functions.
3658 (wait_for_termination): Now takes int * status and bool
3659 interruptible arguments, too. Do not record child status change;
3660 that's now the caller's responsibility. All callers changed.
3661 Reimplement in terms of get_child_status.
3662 (wait_for_termination_1, interruptible_wait_for_termination):
3663 Remove. All callers changed to use wait_for_termination.
3664 * syswait.h: Include <stdbool.h>, for bool.
3665 (record_child_status_change, interruptible_wait_for_termination):
3667 (record_deleted_pid, child_status_changed): New decls.
3668 (wait_for_termination): Adjust to API changes noted above.
3670 * bytecode.c, lisp.h (Qbytecode): Remove.
3671 No longer needed after 2012-11-20 interactive-p changes.
3673 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3675 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3676 the scroll margin, move point outside the margin. (Bug#13055)
3678 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3680 * gtkutil.c (my_log_handler): New function.
3681 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3683 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3685 * lisp.h (modify_region): Rename to...
3686 (modify_region_1): ...new prototype.
3687 * textprop.c (modify_region): Now static. Adjust users.
3688 * insdel.c (modify_region): Rename to...
3689 (modify_region_1): ...new function to work with current buffer.
3690 Adjust comment and users. Use true and false for booleans.
3692 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3694 * alloc.c (free_save_value): New function.
3695 (safe_alloca_unwind): Use it.
3696 * lisp.h (free_save_value): New prototype.
3697 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3699 (save_excursion_restore): Adjust to match saved data structure.
3700 Use free_save_value to offload some work from GC. Drop obsolete
3703 2012-12-03 Chong Yidong <cyd@gnu.org>
3705 * fileio.c (Vauto_save_list_file_name): Doc fix.
3707 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3709 * w32fns.c: Remove prototype of atof.
3710 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3712 (file_dialog_callback): Make it UINT_PTR.
3714 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3717 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3718 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3721 2012-12-03 Glenn Morris <rgm@gnu.org>
3723 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3725 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3727 Fix xpalloc confusion after memory is exhausted.
3728 * alloc.c (xpalloc): Comment fix.
3729 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3730 and signals an error, do not clear charset_table_size, as
3731 charset_table is still valid.
3732 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3734 Use execve to avoid need to munge environ (Bug#13054).
3735 * callproc.c (Fcall_process):
3736 * process.c (create_process):
3737 Don't save and restore environ; no longer needed.
3738 * callproc.c (child_setup):
3739 Use execve, not execvp, to preserve environ.
3741 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3743 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3745 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3747 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3748 display for sliced images (Bug#10500).
3750 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3752 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3754 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3755 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3757 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3759 * xdisp.c (window_outdated): Remove eassert since it hits
3760 some suspicious corner cases (see Bug#13007 and Bug#13012).
3761 (mode_line_update_needed): New function.
3762 (redisplay_internal, redisplay_window): Use it.
3763 (ensure_selected_frame): New function.
3764 (redisplay_internal, unwind_redisplay): Use it.
3765 (redisplay_internal): Move comment about buffer_shared...
3766 (buffer_shared_and_changed): ...near to its real use.
3768 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3770 * callproc.c (Fcall_process): Don't misreport vfork failure.
3772 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3774 * callproc.c (Fcall_process): Fix vfork portability problems.
3775 Do not assume that fd[0], count, filefd, and save_environ survive
3776 vfork. Fix bug whereby wrong errno value could be reported for
3777 pipe failure. Some minor cleanups, too, as follows. Move buf and
3778 bufsize to the context where they're needed. Change new_argv to
3779 be of type char **, as this is more convenient and avoids casts.
3780 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3781 Now local constants, not macros.
3783 2012-11-18 Kenichi Handa <handa@gnu.org>
3785 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3786 for the variable "f".
3788 2012-11-13 Kenichi Handa <handa@gnu.org>
3790 * font.c (font_unparse_xlfd): Exclude special characters from the
3791 generating XLFD name.
3793 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3795 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
3796 * dired.c (stat_uname, stat_gname):
3797 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
3799 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

3807 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3808 Assume EIO and EAGAIN are defined.
3809 * unexcoff.c (write_segment): Assume EFAULT is defined.

3818 violations when repeatedly clicking on the "Top" link of the
3819 "bread-crumbs" in Info buffers.

3829 were always defined.
3831 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3833 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3834 between bpos_covered and bpos_max. This fixes cursor display when
3835 several display strings follow each other.
3837 * .gdbinit (pgx): If the glyph's object is a string, display the
3838 pointer to string data, rather than the value of the string object
3839 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3841 * indent.c (Fvertical_motion): If the starting position is covered
3842 by a display string, return to one position before that, to avoid
3843 overshooting it inside move_it_to. (Bug#12930)
3845 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3847 * frame.h (struct frame): Remove display_preempted member

3850 * w32menu.c (pending_menu_activation): Remove since not
3852 (set_frame_menubar): Adjust user.
3853 * w32term.h (struct x_output): Drop outdated #if 0 code.
3854 (struct w32_output): Use bitfields for explicit_parent,
3855 asked_for_visible and menubar_active members.
3856 Drop unused pending_menu_activation member.
3857 * xterm.h (struct x_output): Drop outdated #if 0 code.
3858 Use bitfields for explicit_parent, asked_for_visible,
3859 has_been_visible and net_wm_state_hidden_seen members.
3861 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3863 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3864 of a literal "/". (Bug#12955)
3865 (gl-stamp): Invoke fc.exe directly, not through cmd.
3867 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3869 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3870 * dired.c: Assume HAVE_DIRENT_H.
3871 (NAMLEN): Remove, replacing with ...
3872 (dirent_namelen): New function. All uses changed. Use the GNU macro
3873 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3874 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3875 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3876 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3878 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3879 * ndir.h: Rename to ../nt/inc/dirent.h.
3880 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3881 Do not include <dirent.h>; no longer needed.
3882 * w32.c: Include <dirent.h> rather than "ndir.h".
3884 2012-11-23 Chong Yidong <cyd@gnu.org>
3886 * xftfont.c (xftfont_open): Remove duplicate assignment.
3888 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3890 * alloc.c (Fgarbage_collect): Unblock input after clearing
3891 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3892 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3893 * msdos.c (IT_frame_up_to_date): Use it here...
3894 * w32term.c (w32_frame_up_to_date): ...here...
3895 * xterm.c (XTframe_up_to_date): ...and here...
3896 * nsterm.m (ns_frame_up_to_date): ...but not here.
3897 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3899 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3900 Do not check whether GC is in progress.
3902 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3904 * xdisp.c (window_buffer_changed): New function.
3905 (update_menu_bar, update_tool_bar): Use it to
3906 simplify large 'if' statements.
3907 (redisplay_internal): Generalize commonly used
3908 'tail' and 'frame' local variables.
3910 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3912 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3913 with Windows system header.
3915 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3917 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3918 * alloc.c: Assume unistd.h exists.
3919 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3920 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3921 (getwd) [USG]: Remove; no longer needed.
3922 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3923 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3924 * w32.h (getcwd): Remove decl.
3926 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3928 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3929 Make it set selected_window as well.
3930 (update_tool_bar): Use it.
3932 2012-11-21 Ken Brown <kbrown@cornell.edu>
3934 * emacs.c (main): Set the G_SLICE environment variable for all
3935 Cygwin builds, not just GTK builds. See
3936 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3938 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3940 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3941 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3942 Define for the MSVC compiler.
3944 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3946 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3947 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3948 dostounix_filename. Prevents crashes down the road, because
3949 dostounix_filename assumes it gets a unibyte string.
3950 Reported by Michel de Ruiter <michel@sentient.nl>, see

3966 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3968 * eval.c (interactive_p): Remove no-longer-used decl.
3970 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3972 * xdisp.c (buffer_shared): Adjust comment.
3973 (buffer_shared_and_changed): New function.
3974 (prepare_menu_bars, redisplay_internal): Use it to
3975 decide whether all windows or frames should be updated.
3976 (window_outdated): New function.
3977 (text_outside_line_unchanged_p, redisplay_window): Use it.
3978 (redisplay_internal): Likewise. Fix indentation.
3980 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3982 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3983 (syms_of_eval): Remove corresponding defsubr.
3984 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3986 2012-11-19 Daniel Colascione <dancol@dancol.org>
3988 * w32fns.c (Fx_file_dialog):
3989 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3990 cygwin_convert_file_name*.
3992 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3993 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3995 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3997 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3999 2012-11-18 Eli Zaretskii <eliz@gnu.org>
4001 * w32select.c: Include w32common.h before w32term.h, so that
4002 windows.h gets included before w32term.h uses some of its
4003 features, see below.
4005 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
4007 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
4009 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
4011 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
4013 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
4014 (ns_select): Return at once if events are held (Bug#12834).
4016 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
4018 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
4019 Needed following 2012-10-20 change. (Bug#12902)
4021 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
4023 * w32proc.c (waitpid): Remove unused label get_result.
4025 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
4027 * makefile.w32-in (SYSWAIT_H): New macro.
4028 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
4029 ($(BLD)/sysdep.$(O)): Update dependencies.
4031 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4033 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
4034 * callproc.c (relocate_fd): Assume F_DUPFD.
4035 * emacs.c, term.c (O_RDWR): Remove.
4036 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
4037 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
4038 * nsterm.m: Assume <fcntl.h> exists.
4039 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
4040 (create_pty, Fmake_network_process, server_accept_connection)
4041 (wait_reading_process_output, init_process_emacs):
4043 (wait_reading_process_output): Put in a special case for WINDOWSNT
4044 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
4045 It's not clear this is needed, but it's a more-conservative change.
4046 (create_process): Assume FD_CLOEXEC.
4047 (create_process, create_pty): Assume O_NOCTTY.
4048 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
4049 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
4050 Omit if not DOS_NT, since F_GETFL is not defined there.
4051 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
4052 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
4054 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
4055 lack it, since gnulib guarantees this.
4056 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
4058 2012-11-17 Eli Zaretskii <eliz@gnu.org>
4060 * w32.c (faccessat): Pretend that directories have the execute bit
4061 set. Emacs expects that, e.g., in files.el:cd-absolute.
4063 * w32proc.c (create_child): Don't clip the PID of the child
4064 process to fit into an Emacs integer, as this is no longer a
4066 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
4067 reaping only the process specified by PID argument, if that is
4068 positive. Use PID instead of dead_child to know which process to
4069 reap. Wait for the child to die only if WNOHANG is not in
4071 (sys_select): Don't set dead_child.
4073 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
4074 as it is no longer needed.
4076 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
4078 (record_child_status_change): Remove the setting of
4079 record_at_most_one_child for the !WNOHANG case.
4081 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4083 Fix problems in ns port found by static checking.
4084 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4085 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4086 not to process group.
4087 (ns_select): Use emacs_write, not write, as that's more robust
4088 in the presence of signals.
4089 (fd_handler:): Check for read errors.
4091 2012-11-16 Glenn Morris <rgm@gnu.org>
4093 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)

4097 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
4099 2012-11-16 Eli Zaretskii <eliz@gnu.org>
4101 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4102 use the same value of thread handle.
4103 (start_timer_thread): If the timer thread exited (due to error),
4104 clean up by closing the two handles it used. Duplicate the caller
4105 thread's handle here, so it gets duplicated only once, when
4106 launching the timer thread. Set priority of the timer thread, not
4108 (getitimer): Don't duplicate the caller thread's handle here.
4111 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4113 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4116 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4118 Remove no-longer-used pty_max_bytes variable.
4119 * process.c (pty_max_bytes): Remove; unused.
4120 (send_process): Do not set it.
4122 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4124 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4125 Update dependencies.
4127 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4129 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4130 This follows up on the 2012-09-29 patch that removed indirection
4131 for the 'function' field. Reported by Sergey Vinokurov in
4132 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4134 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4136 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4137 different name, as the MS runtime does not have such a function,
4138 and probably never will.) All callers changed. Ignore DIRFD
4139 value if PATH is an absolute file name, to match Posix spec
4140 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4143 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4145 * xdisp.c (echo_area_display, redisplay_internal):
4146 Omit redundant check whether frame_garbaged is set.
4148 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4150 Use faccessat, not access, when checking file permissions (Bug#12632).
4151 This fixes a bug that has been present in Emacs since its creation.
4152 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4153 which must set some sort of record. (Torek's bug report was against
4154 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4155 same common flaw.) See Torek's Usenet posting
4156 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4157 Posted: Fri Apr 8 14:18:56 1983.

4173 * fileio.c (check_existing, check_executable, check_writable)
4175 Use symbolic names instead of integers for the flags, as they're
4177 (check_writable): New arg AMODE. All uses changed.
4178 Set errno on failure.
4179 (Ffile_readable_p): Use faccessat, not stat + open + close.
4180 (Ffile_writable_p): No need to call check_existing + check_writable.
4181 Just call check_writable and then look at errno. This saves a syscall.
4182 dir should never be nil; replace an unnecessary runtime check
4183 with an eassert. When checking the parent directory of a nonexistent
4184 file, check that the directory is searchable as well as writable, as
4185 we can't create files in unsearchable directories.
4186 (file_directory_p): New function, which uses 'stat' on most platforms
4187 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4188 (Ffile_directory_p, Fset_file_times): Use it.
4189 (file_accessible_directory_p): New function, which uses a single
4190 syscall for efficiency.
4191 (Ffile_accessible_directory_p): Use it.
4192 * xrdb.c (file_p): Use file_directory_p.
4193 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4194 * lread.c (openp): When opening a file, use fstat rather than
4195 stat, as that avoids a permissions race. When not opening a file,
4196 use file_directory_p rather than stat.
4197 (dir_warning): First arg is now a usage string, not a format.
4198 Use errno. All uses changed.
4199 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4200 that merely introduced a race.
4201 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4202 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4203 and similarly for the other O_* flags.
4204 * w32.c (sys_faccessat): Rename from sys_access and switch to
4205 faccessat's API. All uses changed.
4206 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4207 (magic_db): Rename from magic_file_p.
4208 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4209 char *, so that we don't have to test for file existence
4210 separately from opening the file for reading. This removes a race
4211 fixes a permission-checking problem, and simplifies the code.
4213 (file_p): Remove; no longer needed.
4215 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4217 Omit glyphs initialization at startup.

4223 * xdisp.c (clear_garbaged_frames): Likewise.
4225 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4227 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4228 passed to pint2str and pint2hrstr to be at most the size of the
4229 frame's decode_mode_spec_buffer. This avoids crashes with very
4230 large values of FIELD_WIDTH argument to decode_mode_spec.
4233 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4235 Fix a race with verify-visited-file-modtime (Bug#12863).
4236 Since at least 1991 Emacs has ignored an mtime difference of no
4237 more than one second, but my guess is that this was to work around
4238 file system bugs that were fixed long ago. Since the race is
4239 causing problems now, let's remove that code.
4240 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4241 whose time stamp is off by no more than a second. Insist that the
4242 file time stamps match exactly.
4244 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4246 * frame.h (struct frame): Convert external_tool_bar member to
4247 1-bit unsigned bitfield.

4249 all users are long dead. Adjust comment on mouse_position_hook.
4251 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4253 Simplify by using FOR_EACH_FRAME here and there.
4254 * frame.c (next_frame, prev_frame, other_visible_frames)
4255 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4256 * w32term.c (x_window_to_scroll_bar): Likewise.
4257 * window.c (window_list): Likewise.
4258 * xdisp.c (x_consider_frame_title): Likewise.
4259 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4260 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4261 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4262 * xmenu.c (menubar_id_to_frame): Likewise.
4263 * xselect.c (frame_for_x_selection): Likewise.
4264 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4265 (x_window_to_menu_bar): Likewise.
4266 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4268 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4270 * data.c (Qdefalias_fset_function): Now static.
4272 Another tweak to vectorlike_header change.
4273 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4274 Remove, and replace all uses with ...
4275 (next_in_free_list, set_next_in_free_list):
4276 New functions, which respect C's aliasing rules better.
4278 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4280 * window.c (list4i): Rename from 'quad'. All uses changed.
4281 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4283 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4285 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4286 warning about mixing declarations and code in ISO C90.
4288 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4290 * window.c (Fsplit_window_internal): Set combination limit of
4291 new parent window to t iff Vwindow_combination_limit is t;
4292 fixing a regression introduced with the change from 2012-09-22.
4293 (Fset_window_combination_limit): Fix doc-string.
4295 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4297 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4298 amount when the scroll margins are too large. When scrolling
4299 backwards in the buffer, give up if cannot reach point or the
4300 scroll margin within a reasonable number of screen lines.
4301 Fixes point position in window under scroll-up/down-aggressively when
4302 point is positioned many lines beyond the window top/bottom.
4305 * ralloc.c (relinquish): If real_morecore fails to return memory
4306 to the system, don't crash; instead, leave the last heap
4307 unchanged and return. (Bug#12774)
4309 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4311 * lisp.h (AUTOLOADP): New macro.

4316 (Finteractive_form): Simplify.
4317 (Fquo): Don't insist on having at least 2 arguments.
4318 (Qdefalias_fset_function): New var.
4320 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4322 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4324 * nsfont.m (Qcondensed, Qexpanded): New variables.

4326 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4328 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4330 Fix recently introduced crash on MS-Windows (Bug#12839).
4331 * w32term.h (struct scroll_bar): Use convenient header.
4332 (SCROLL_BAR_VEC_SIZE): Remove.
4333 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4335 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4337 Tweak last vectorlike_header change.
4338 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4339 vectorlike object on the free list. This is introduced to avoid
4340 some (but not all) pointer casting and aliasing problems, see
4341 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4342 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
4344 (xvectype, xvecsize): Use them to examine Lisp_Object values.
4346 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4348 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4349 been removed, so remove them here also.
4351 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4353 * doc.c (Fdocumentation): Handle new property
4354 dynamic-docstring-function to replace the old ad-advice-info.

4374 special hash function containing a comparison that always yields 1.
4376 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4378 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4379 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4380 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4383 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4385 * image.c (xpm_make_color_table_h): Fix compiler error because
4386 make_hash_table changed.

4390 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4392 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4394 Use ad-hoc comparison function for the profiler's hash-tables.
4395 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4396 (make_log): Use them.
4397 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4398 call Fequal any more.

4408 (hash_lookup, hash_remove_from_table): Move assertion checking of
4409 hashfn result here. Check hash-equality before calling cmpfn.

4446 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4447 (Fmake_bool_vector): Likewise.
4448 (struct large_vector): New type to represent allocation unit for
4449 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4450 (large_vectors): Change type to struct large_vector.
4451 (allocate_vector_from_block): Simplify.
4452 (PSEUDOVECTOR_NBYTES): Replace with...

4474 * keyboard.c (event_to_kboard): Do not dereference
4475 frame_or_window field of SELECTION_REQUEST_EVENT
4476 and SELECTION_CLEAR_EVENT events (Bug#12814).

4479 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4481 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4482 such as Scroll Lock, if the respective keys are treated as
4483 function keys, not as modifiers. This avoids destroying non-ASCII
4484 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4486 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4488 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4490 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4492 Restore some duplicate definitions (Bug#12814).
4493 This undoes part of the 2012-11-03 changes. Some people build
4494 with plain -g rather than with -g3, and they need the duplicate
4495 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4496 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4497 Define as macros, as well as as enums or as constants.

4501 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4502 to keypad keys (Bug#12816).
4504 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4506 Minor adjustments of recently-changed frame functions.
4507 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4508 known to be a frame (we're in the FRAMEP branch).
4509 * lisp.h (Qframep): Remove decl. frame.h declares this.
4510 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4511 since they're meant for Lisp fixnum values.
4513 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4515 * window.c (Fwindow_combination_limit): Revert to the only
4516 required argument and adjust docstring as suggested in
4517 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4518 by Martin Rudalics <rudalics@gmx.at>.

4571 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4572 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4573 file descriptor 2 for standard error. (Bug#12805)
4575 2012-11-05 Chong Yidong <cyd@gnu.org>
4577 * process.c (wait_reading_process_output): Revert previous change.
4579 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4581 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4582 This removes code that has been obsolete since around 1990.
4583 * callproc.c (Fcall_process):
4585 * process.c (create_process):
4586 * term.c (dissociate_if_controlling_tty):
4587 Assume setsid exists.

4606 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4608 Remove EMACS_OUTQSIZE+sleep hack.
4609 * dispnew.c (update_frame_1): Remove hack for terminals slower
4610 than 2400 bps, which throttled Emacs by having it sleep.
4611 This code hasn't worked since at least 2007, when the multi-tty stuff
4612 was added, and anyway those old terminals are long dead.
4613 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4614 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4616 Fix data-loss with --version (Bug#9574).
4617 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4618 as we can't assume that emacs_strerror is initialized, and strerror
4619 is good enough here.
4620 (main): Invoke atexit earlier, to catch earlier instances of
4621 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4623 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4625 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4626 (keyDown): Remap keypad keys to X11 virtual key codes.
4628 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4630 Fix data-loss with --batch (Bug#9574).
4631 * emacs.c: Include <close-stream.h>.
4632 (close_output_streams): New function.
4633 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4634 and handles errors appropriately.
4635 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4638 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4639 The symptom is a diagnostic "GLib-WARNING **: In call to
4640 g_spawn_sync(), exit status of a child process was requested but
4641 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4642 waitpid(), so exit status can't be returned." The diagnostic
4643 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4644 The real bug is a race condition between Emacs and glib: Emacs
4645 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4646 so that glib can't find it. Work around the bug by invoking
4647 waitpid only on subprocesses that Emacs itself creates.
4648 * process.c (create_process, record_child_status_change):
4649 Don't use special value -1 in pid field, as the caller now must
4650 know the pid rather than having the callee infer it.
4651 The inference was sometimes incorrect anyway, due to another race.
4652 (create_process): Set new 'alive' member if child is created.
4653 (process_status_retrieved): New function.
4654 (record_child_status_change): Use it.
4655 Accept negative 1st argument, which means to wait for the
4656 processes that Emacs already knows about. Move special-case code
4657 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4658 processes that have already been waited for, by testing and
4659 clearing new 'alive' member.
4660 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4661 now does this internally.
4662 (handle_child_signal): Let record_child_status_change do all
4663 the work, since we do not want to reap all exited child processes,
4664 only the child processes that Emacs itself created.
4665 * process.h (Lisp_Process): New boolean member 'alive'.
4667 Omit duplicate definitions no longer needed with gcc -g3.
4668 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4669 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4670 Define only as macros. There's no longer any need to also define
4671 these symbols as enums or as constants, since we now assume
4672 gcc -g3 when debugging.
4674 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4676 * lisp.mk: Adjust comments to the fact that term/internal is now
4677 loaded from loadup.el.
4679 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4680 (msdos_fatal_signal): New function.
4681 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4684 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4685 for GCC versions before 4.
4686 (emacs_raise): Define to call msdos_fatal_signal.
4688 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4689 iterator when starting in the middle of a display or overlay
4692 2012-11-03 Chong Yidong <cyd@gnu.org>
4694 * process.c (wait_reading_process_output): Clean up the last
4697 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4699 * process.c (wait_reading_process_output): Avoid a race condition
4700 with SIGIO delivery (Bug#11536).
4702 2012-11-03 Chong Yidong <cyd@gnu.org>
4704 * buffer.c (cursor_type): Untabify docstring.
4706 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4708 * frame.h (struct frame): Drop can_have_scroll_bars member
4709 which is meaningless for a long time. Adjust comments.
4710 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4711 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4713 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4715 * window.c (decode_next_window_args): Update window arg after
4716 calling decode_live_window and so fix crash reported at
4717 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4718 by Juanma Barranquero <lekktu@gmail.com>.
4719 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4720 * font.c (Ffont_at): Likewise.
4722 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4724 * widget.c (resize_cb): New function.
4725 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4726 (EmacsFrameResize): Check if all is up to date before changing frame
4729 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4731 Implement backtrace output for fatal errors on MS-Windows.
4732 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4733 (BACKTRACE_LIMIT_MAX): New macro.
4734 (w32_backtrace): New function.
4735 (emacs_abort): Use w32_backtrace when the user chooses not to
4736 attach a debugger. Update the text of the abort dialog.
4738 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4740 Window-related stuff cleanup here and there.
4741 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4742 Use decode_any_window.
4743 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4744 * xdisp.c (Fformat_mode_line): Likewise.
4745 * font.c (Ffont_at): Use decode_live_window.
4746 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4747 * window.c (decode_next_window_args): Likewise.
4748 (decode_any_window): Remove static.
4749 * window.h (decode_any_window): Add prototype.
4750 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4751 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4754 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4756 Remove pad from struct input_event.
4757 * termhooks.h (struct input_event): Remove padding field.
4759 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4760 member is never cons for a long time. Adjust comment.
4761 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4762 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4763 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4764 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4766 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4768 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4770 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4772 Fix crash when using Emacs as commit editor for git (Bug#12697).
4773 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4774 and it is configured in conf_post.h.
4775 (Fcall_process): Don't invoke both setsid and setpgid; the former
4776 is enough, if it exists.
4777 * callproc.c (Fcall_process, child_setup):
4778 * process.c (create_process): Use setpgid.
4779 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4781 * dispnew.c (init_display): Initialize the foreground group
4782 if we are running a tty display.
4783 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4784 * lisp.h (init_foreground_group): New decl.
4785 * sysdep.c (inherited_pgroup): New static var.
4786 (init_foreground_group, tcsetpgrp_without_stopping)
4787 (narrow_foreground_group, widen_foreground_group): New functions.
4788 (init_sys_modes): Narrow foreground group.
4789 (reset_sys_modes): Widen foreground group.
4791 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4793 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4795 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4797 * minibuf.c (read_minibuf): Restore current buffer since
4798 choose_minibuf_frame calling Fset_frame_selected_window may
4799 change it (Bug#12766).
4801 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4803 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4805 2012-10-30 Kenichi Handa <handa@gnu.org>
4807 * font.c (Ffont_at): If WINDOW is specified and it is not
4808 displaying the current buffer, signal an error.
4810 2012-10-29 Daniel Colascione <dancol@dancol.org>
4812 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4813 In preparation for fixing bug#12739, move these functions from
4816 * coding.h, coding.c: ... to here, and compile them only when
4817 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4818 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4820 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4822 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4823 (timer_loop, getitimer, setitimer): Use it instead of
4824 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4826 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4829 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4831 * nsterm.m (NO_APPDEFINED_DATA): New define.
4832 (last_appdefined_event_data): New variable
4833 (last_appdefined_event): Remove.
4834 (ns_select): Initialize t from last_appdefined_event_data instead
4835 of [last_appdefined_event data1].
4836 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4837 remove last_appdefined_event (Bug#12698).
4839 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4841 * frame.c (x_set_font): Catch internal error.
4843 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4845 Avoid overflow in w32 implementation of interval timers.
4846 When possible, for ITIMER_PROF count only times the main thread
4848 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4849 'volatile ULONGLONG' types. All the other data which was
4850 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4851 (GetThreadTimes_Proc): New typedef.
4852 (w32_get_timer_time): New function, returns a suitable time value
4854 (timer_loop): Enter critical section when accessing ULONGLONG
4855 values of the itimer_data struct, as these accesses are no longer
4856 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4857 Remove unused variable.
4858 (init_timers): Initialize s_pfn_Get_Thread_Times.
4859 (start_timer_thread): Don't assign itimer->caller_thread here.
4860 (getitimer): Assign itimer->caller_thread here.
4861 (setitimer): Always call getitimer to get the value of ticks_now.
4862 (sys_spawnve): Avoid compiler warning about format mismatch.
4864 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4866 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4867 mouse movement events if the menu bar is active. This avoids
4868 producing a busy "hour-glass" cursor by Windows if the mouse
4869 pointer is positioned over a tooltip shown for some menu item.
4871 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4873 Don't assume process IDs fit in int.
4874 * emacs.c (shut_down_emacs) [!DOS_NT]:
4875 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4876 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4877 Use pid_t, not int, to store process IDs, as 'int'
4878 is not wide enough on a few platforms (e.g., AIX and IRIX).
4880 2012-10-23 Kenichi Handa <handa@gnu.org>
4882 The following change is to make face-font-rescale-alist work
4883 correctly for non-ASCII fonts.
4885 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4886 (font_open_for_lface): Handle Vface_font_rescale_alist.
4888 2012-10-23 Chong Yidong <cyd@gnu.org>
4890 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4892 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>
4894 * nsfont.m (nsfont_open, ns_glyph_metrics): Force integer advancement
4896 (nsfont_draw): Turn off LCD-smoothing (Bug#11484).
4898 * xterm.c (x_focus_changed): Check if daemonp when sending focus in
4901 2012-10-21 Glenn Morris <rgm@gnu.org>
4903 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4905 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4907 Port to OpenBSD 5.1.
4908 * frame.c (Fmouse_position, Fmouse_pixel_position):
4909 * xdisp.c (produce_stretch_glyph):
4910 Declare local vars only when they're needed.
4911 This is clearer and avoids a warning on OpenBSD about unused vars.
4912 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
4913 This is safer, and avoids OpenBSD warnings about unused vars.
4914 * keyboard.c (record_menu_key): Remove unnecessary decl.
4915 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4916 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4917 as our definition clashes with OpenBSD's.
4918 * xfaces.c (load_face_colors, check_lface_attrs)
4919 (get_lface_attributes_no_remap, get_lface_attributes)
4920 (lface_fully_specified_p, x_supports_face_attributes_p)
4921 (tty_supports_face_attributes_p, face_fontset, realize_face)
4922 (realize_x_face, realize_tty_face):
4923 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4924 merely Lisp_Object *. This is more informative and avoids
4925 a warning on OpenBSD about accessing beyond an object's size.
4927 2012-10-20 Chong Yidong <cyd@gnu.org>
4929 * lread.c (Fload): Doc fix (Bug#12592).
4931 2012-10-19 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)
4933 * font.c (Ffont_at): Fix previous change.
4935 2012-10-19 Eli Zaretskii <eliz@gnu.org>
4937 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
4938 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

4948 2012-10-18 Jan Djärv <jan.h.d@swipnet.se>
4950 * nsterm.m (ns_select): Check writefds before call to
4951 FD_ISSET (Bug#12668).
4953 2012-10-18 Daniel Colascione <dancol@dancol.org>
4955 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4956 (staticpro): If we run out of staticpro slots, die with an
4957 informative error instead of just calling emacs_abort.
4959 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4961 Fix two flaws reported by Dmitry Antipov.
4962 * window.c (Ftemp_output_buffer_show): Remove.
4963 (Fwindow_vscroll, Fset_window_vscroll): Use decode_live_window.
4964 (syms_of_window): Remove defsubr for Stemp_output_buffer_show.

4982 (unixtodos_filename, init_winsock, srandom, random, sys_pipe)
4983 (set_process_dir, sys_spawnve, register_child, sys_sleep, getwd)
4984 (sys_link): Add prototypes.
4986 * w32.c: Include w32select.h.
4987 (sys_access, e_malloc, sys_select): Add prototypes.
4988 (emacs_gnutls_pull): 'timeout' is now EMACS_TIME, not struct timeval.

4992 * unexw32.c: Include lisp.h and w32.h.
4994 * term.c [WINDOWSNT]: Include w32term.h.

4998 * fileio.c [WINDOWSNT]: Include w32.h.
5000 * dispnew.c [WINDOWSNT]: Include w32.h.
5002 * cygw32.c (Fcygwin_convert_path_to_windows)
5003 (Fcygwin_convert_path_from_windows): Use EQ to compare 2
5004 Lisp_Object values. (Bug#12661)
5006 * w32fns.c (w32_msg_pump): Use XIL instead of casting an integer
5007 to Lisp_Object. (Bug#12661)
5009 2012-10-17 Kenichi Handa <handa@gnu.org>

5022 * buffer.h (BUFFER_CHECK_INDIRECTION): New macro.
5023 * buffer.c (compact_buffer, set_buffer_internal_1): Use it.

5043 2012-10-15 Martin Rudalics <rudalics@gmx.at>
5045 * window.c (Fwindow_end): Rewrite check whether cached position
5046 can be used (Bug#12600).

5050 2012-10-15 Daniel Colascione <dancol@dancol.org>
5052 * dbusbind.c: Fix cygw32 build break when compiling with dbus
5053 enabled by undefining the symbol "interface", which the platform
5054 headers define to something incompatible.
5056 2012-10-14 Daniel Colascione <dancol@dancol.org>
5058 * image.c (init_tiff_functions, init_imagemagick_functions)

5068 * gtkutil.c (xg_set_widget_bg): Divide by 65535 (Bug#12612).
5070 2012-10-13 HANATAKA, Shinya <bogytech@gmail.com> (tiny change)

5075 2012-10-13 Andreas Schwab <schwab@linux-m68k.org>
5077 * fileio.c: Formatting fixes.
5079 2012-10-13 Paul Eggert <eggert@cs.ucla.edu>
5081 Fix some stat-related races.
5082 * fileio.c (Fwrite_region): Avoid race condition if a file is
5083 removed or renamed by some other process immediately after Emacs
5084 writes it but before Emacs stats it. Do not assume that stat (or
5086 * image.c (slurp_file): Resolve the file name with fopen + fstat
5087 rather than stat + fopen.
5088 (pbm_read_file) [0]: Remove unused code with stat race.
5089 * process.c (allocate_pty) [HAVE_PTYS && !PTY_ITERATION && !PTY_OPEN]:
5090 Remove ineffective code with stat race.
5092 2012-10-12 Stefan Monnier <monnier@iro.umontreal.ca>

5104 (setPosition:portion:whole:): Send SIGIO to ourselves if apploopnr
5105 is zero (Bug#12384).
5107 2012-10-12 Juanma Barranquero <lekktu@gmail.com>
5109 * makefile.w32-in ($(BLD)/w32select.$(O)): Update dependencies.

5113 * makefile.w32-in ($(BLD)/fileio.$(O)): Add sys/file.h.
5115 * fileio.c (check_existing): New function.
5116 (make_temp_name, Ffile_exists_p, Ffile_writable_p): Call it
5117 instead of calling 'stat', when what's needed is to check whether
5118 a file exists. This avoids expensive system calls on MS-Windows.
5121 * w32.c (init_environment): Call 'check_existing' instead of 'stat'.
5123 * lread.c (openp) [WINDOWSNT]: Call 'access' instead of 'stat' to
5124 determine whether a file exists and is not a directory.
5126 * lisp.h (check_existing): Add prototype.
5128 2012-10-12 Jan Djärv <jan.h.d@swipnet.se>
5130 * nsfont.m (nsfont_open): Remove font cache, it is not GC correct.
5132 2012-10-12 Glenn Morris <rgm@gnu.org>

5160 Use bool for booleans.
5161 * lread.c (safe_to_load_version): Rename from safe_to_load_p,
5162 as it's not a predicate. All uses changed. Omit unnecessary
5165 2012-10-11 Dmitry Antipov <dmantipov@yandex.ru>
5167 * editfns.c (save_excursion_save): Use nil if mark points to nowhere.
5168 (save_excursion_restore): Do not restore mark if it was not saved.
5170 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
5172 * marker.c (cached_modiff): EMACS_INT, not int.
5174 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
5175 instead of having a wrong decl.
5176 * nsmenu.m (waiting_for_input): Remove wrong decl.
5178 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>

5213 (detect_input_pending_run_timers):
5214 * process.c (wait_reading_process_output):
5215 Use unsigned for counter where wraparound-on-overflow is desired,
5216 since unsigned is guaranteed to have that behavior and signed is not.
5217 (read_char): Use ptrdiff_t for string length.
5218 (get_input_pending): Remove first argument, since it was always
5219 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5220 and behave as if it had that value. Return new value of
5221 input_pending. All callers changed.
5222 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5223 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5225 * keymap.c (push_key_description): Omit last arg, which was always 1.
5226 All callers changed.
5228 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
5230 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

5246 Don't include termopts.h.
5248 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5250 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5252 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5254 * commands.h (immediate_quit): Remove duplicate decl.
5256 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5258 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
5260 (nsfont_open): Remove setting of Vfonts_in_cache.
5261 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5263 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5265 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5266 match what GetLastError returns. Explain why the function is
5269 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5270 'is_tooltip_frame', to avoid confusion with its global namesake.
5272 2012-10-08 Daniel Colascione <dancol@dancol.org>
5274 * xdisp.c (start_hourglass): Call w32_note_current_window when
5275 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5276 build that caused Emacs to display the hourglass cursor forever.
5278 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5279 which is broken under remote desktop, calculate the number of
5280 colors available for a display based on the display's number of
5281 planes and number of bits per pixel per plane. (bug#10397).
5283 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5285 * nsfont.m (Vfonts_in_cache): New variable.
5286 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5287 are used. Add cached fonts to Vfonts_in_cache.
5288 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5290 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5292 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5294 (FONT_H): Define after FRAME_H.
5295 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5296 Update dependencies.
5298 * w32term.c: Remove leftover declaration of keyboard_codepage.
5300 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5302 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5303 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5304 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5305 (GLOBAL_SOURCES): Add cygw32.c.
5306 ($(BLD)/unexw32.$(O)):
5308 ($(BLD)/w32console.$(O)):
5309 ($(BLD)/w32fns.$(O)):
5310 ($(BLD)/w32heap.$(O)):
5311 ($(BLD)/w32menu.$(O)):
5312 ($(BLD)/w32proc.$(O)): Add w32common.h.
5314 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5316 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5318 2012-10-08 Daniel Colascione <dancol@dancol.org>
5320 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5321 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5322 accidental message numbering hole. Change other messages to
5325 * w32select.h (HAVE_W32SELECT): Remove.
5327 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5328 w32common.h instead of w32heap.h.
5330 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5331 (get_allocation_unit, get_processor_type, get_w32_major_version)
5332 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5333 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5334 (OS_NT, os_subtype, cache_system_info): Move declarations to
5337 * w32heap.c: Include w32common.h.
5338 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5339 (w32_minor_version, w32_build_number, w32_subtype):
5340 Remove duplicate definitions.
5342 * w32fns.c: Include w32common.h; include w32heap.h only in
5345 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5346 Use `report_file_error' instead of `error' in order to better
5347 inform users of what went wrong. Increase NTGUI_UNICODE file
5348 dialog box file name length to 32k, the maximum allowed by the NT
5351 * w32common.h: New file.
5352 (ROUND_UP, ROUND_DOWN, get_page_size)
5353 (get_allocation_unit, get_processor_type, get_w32_major_version)
5354 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5355 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5356 (OS_NT, os_subtype, cache_system_info): Move here.
5358 * unexw32.c, unexcw.c: Include w32common.h.
5360 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5361 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5362 to call syms_of_w32select.
5364 * cygw32.h: Remove obsolete EXFUN declarations.
5366 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5368 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5369 of w32inevt.o from SOME_MACHINE_OBJECTS.
5371 2012-10-08 Daniel Colascione <dancol@dancol.org>
5373 * image.c: Permanent fix for JPEG compilation issue --- limit
5374 jpeglib `boolean' redefinition to Cygwin builds.
5376 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5378 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5380 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5383 2012-10-08 Daniel Colascione <dancol@dancol.org>
5385 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5386 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5387 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5388 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5389 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5390 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5391 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5392 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5393 now a supported configuration.
5395 * Makefile.in: consolidate image variables into LIBIMAGE; add
5396 W32_OBJ and W32_LIBS. Compile new files.
5399 (_DebPrint) declare tracing facility for W32 debugging. We need
5400 to unify tracing later.
5402 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5403 unconditional use of W32 Unicode functions. Cygwin runs only on
5404 100% Unicode operating systems.
5406 * cygw32.c: New file. Define Cygwin-specific facilities.
5407 (Fcygwin_convert_path_to_windows)
5408 (Fcygwin_convert_path_from_windows): New user functions for
5409 accessing Cygwin path-munging routines.
5411 * cygw32.h: New file.
5412 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5413 UTF-16LE strings temporarily inside non-Lisp-visible string
5416 (w32_strerror): Just what it says on the tin.
5418 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5419 also run for Cygwin; both systems have the same problem with using
5420 GUI facilities in a forked child. Also call syms_of_cygw32,
5421 syms_of_w32select in correct places.
5423 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5424 needs fork-then-exec for daemon launching.
5426 * font.h: Include frame.h.
5428 * image.c: Use the image library cache machinery only when we're
5429 compiling for native WINDOWSNT; Cygwin can use shared libraries
5430 like any other Unixlike system.
5432 * keyboard.c: Clarify a comment regarding the input loop.
5434 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5435 functions directly instead of trying to detect at runtime that our
5436 host operating system supports them. We make this change for two
5437 reasons: Cygwin lacks support for the multibyte character
5438 conversion functions used by the legacy menu code, and Cygwin
5439 never needs to rely on non-Unicode APIs.
5441 * unexw32.c (hinst): Declare extern.
5443 * w32.c: Change header order;
5444 (w32_strerror): Move to w32fns.c because we need it for
5445 non-WINDOWSNT builds.
5447 * w32.h: Add #error macro to make sure we don't include w32.h for
5448 Cygwin builds. Remove w32select declarations.
5450 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5451 w32fns.c. w32console.c is WINDOWSNT-only.
5453 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5454 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5456 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5457 (w32_major_version, w32_minor_version, w32_build_number)
5458 (os_subtype, sound_type): Define here
5459 (w32_defined_color): Make color parameter const for consistency
5460 with other _defined_color functions.
5461 (w32_createwindow): Unconditionally call w32_init_class instead of
5462 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5463 through the code is complex and unnecessary because class
5464 registration is practically free.
5465 (w32_name_of_message): New EMACSDEBUG-only function.
5466 (Fset_message_beep): Move here
5467 (Fx_open_connection): Require that the display name for Windows be
5468 "w32" for consistency, emacsclient disambiguation, and maybe, one
5469 day, multi-window-system support.
5470 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5471 Cygwin files for W32 GUI facilities, since these clearly don't
5472 expect Cygwin names.
5473 (_DebPrint): Define.
5474 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5475 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5476 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5477 (w32_last_error): Remove.
5479 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5481 * w32heap.c (syspage_mask): Declare here.
5482 (cache_system_info): Remove.
5484 * w32inevt.c (faked_key): Define globally, not statically.
5485 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5486 (w32_console_toggle_lock_key): Move to w32fns.c.
5488 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5490 * w32proc.c (_DebPrint): Move to w32fns.c.
5491 * w32select.c: Include string.h, stdio.h for Cygwin.
5492 * w32select.h: New File.
5494 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5496 (w32_message_fd): New variable. Under Cygwin, holds the file
5497 descriptor the system used to tell us about pending thread
5500 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5501 that prevented compilation under non-WINDOWSNT systems.
5503 (w32_initialize): Open /dev/windows and assign it to
5504 w32_message_fd. Provide w32 feature.
5506 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5507 (WM_EMACS_INPUT_READY): add.
5508 (prepend_msg, w32_message_fd): Declare globally.
5511 (keyboard_handle): Use only when WINDOWSNT.
5512 (notify_msg_ready): New function. Posts a message to the main
5513 thread's message queue under CYGWIN, which wakes up the main
5514 thread from select(2) by making the /dev/windows file descriptor
5515 ready. Under WINDOWSNT, it sets an event the same way the old
5518 (post, prepend_msg): Actually call notify_msg_ready instead of
5519 setting the input event directly.
5521 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5523 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5524 but it still has blocs in it, don't return it to the system,
5525 instead of aborting. (Bug#12402)
5527 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5529 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5531 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5532 MAC_OS_X_VERSION_10_6.

5535 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5536 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5537 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5539 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5540 MAC_OS_X_VERSION_10_4.
5542 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5543 MAC_OS_X_VERSION_10_2.
5545 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5547 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5548 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5550 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5551 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5552 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):

5560 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5562 Improve sys_siglist detection.
5563 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5564 defined as a macro, as is done in Solaris.
5565 (sys_siglist_entries): New macro.
5566 (save_strsignal): Use it.
5567 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5568 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5570 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5572 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5573 fullscreen/Fullscreen.
5575 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5576 tobar_height is new.
5578 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5579 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5580 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5581 (windowDidResize:): Check for correct window if old style fullscreen.
5582 Capitalize word in comment. Remove incorrect comment.
5583 (initFrameFromEmacs:): tbar_height renamed tibar_height.

5593 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5595 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5597 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5599 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5600 that time stamps of directories could also be changed.
5601 Don't request the too broad GENERIC_WRITE, only the more restrictive
5602 FILE_WRITE_ATTRIBUTES access rights.
5604 * fileio.c (Fset_file_times): Special-case ignoring errors for
5605 directories only on MSDOS, not on MS-Windows.
5607 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5609 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5611 2012-10-04 Eli Zaretskii <eliz@gnu.org>

5614 see whether CreateFile failed.
5616 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5618 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5619 to avoid similar races.
5620 * keyboard.c (pending_signals): Now bool, not int.
5622 Port timers to OpenBSD, plus check for timer failures.
5623 OpenBSD problem reported by Han Boetes.
5624 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5626 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5627 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5628 like OpenBSD, which has timer_settime but does not declare it.
5629 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5630 whether to use itimerspec-related primitives. All uses of
5631 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5633 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5635 * profiler.c (handle_profiler_signal): Fix a malloc race
5636 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5638 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5640 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5642 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5644 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5645 consistent with the change in return value of 'safe_strsignal'.
5647 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5649 Prefer plain 'static' to 'static inline' (Bug#12541).
5650 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5651 (bidi_set_sor_type, bidi_push_embedding_level)
5652 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

5657 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5658 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5659 Now 'static', not 'static inline'.
5661 Count overruns when profiling; change units to ns.
5662 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5663 Give extra weight to samples after overruns, to attempt to count
5664 the time more accurately.
5665 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5666 the underlying primitives nominally do ns.
5667 (Fprofiler_cpu_start): Document the change. Mention that
5668 the sampling intervals are only approximate.
5670 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5672 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5674 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5675 case for the special 0 coding-system.
5677 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5678 (Fmake_overlay): Remove redundant tests.
5679 (fix_start_end_in_overlays): Remove redundant recentering.
5681 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5683 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5684 Update dependencies.
5686 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5688 Fix a malloc race condition involving strsignal.
5689 A signal can arrive in the middle of a malloc, and Emacs's signal
5690 handler can invoke strsignal, which can invoke malloc, which is
5691 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5692 Fix it by altering the signal handler so that it does not invoke
5694 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5695 * process.c (status_message): Use const pointer, in case strsignal
5696 is #defined to safe_strsignal.
5697 * sysdep.c (sys_siglist, init_signals): Always define and
5698 initialize a substitute sys_siglist if the system does not define
5699 one, even if HAVE_STRSIGNAL.
5700 (safe_strsignal): Rename from strsignal. Always define,
5701 using sys_siglist. Return a const pointer.
5702 * syssignal.h (safe_strsignal): New decl.
5703 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5705 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5707 * w32proc.c (timer_loop): Fix code that waits for timer
5708 expiration, to avoid high CPU usage.
5710 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5712 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5713 (sweep_weak_table): Remove redundant prototypes.
5715 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5717 * emacs.c: Move the inclusion of TERM_HEADER after including
5718 windows.h on WINDOWSNT. This avoids compilation problems with
5721 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5723 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5724 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5725 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5726 as the previous version used 'void *'.
5728 * ralloc.c (ROUNDUP): Fix last change.
5729 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5732 * w32proc.c <disable_itimers>: New static flag.
5733 (init_timers): Initialize it to zero, after creating the critical
5734 sections used by the timer threads.
5735 (term_timers): Set to 1 before deleting the critical sections.
5736 (getitimer, setitimer): If disable_itimers is non-zero, return an
5737 error indication without doing anything. Reported by Fabrice
5738 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5739 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5741 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5744 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5745 term_ntproc after all the other bookkeeping, to get timers working
5746 as long as possible.
5748 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5750 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5751 Suggested by Juri Linkov in
5752 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5754 Prefer plain 'static' to 'static inline' (Bug#12541).
5755 With static functions, modern compilers inline pretty well by
5756 themselves; advice from programmers often hurts as much as it helps.
5757 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5758 this change shrinks the text size of the Emacs executable by 1.1%
5759 without affecting CPU significantly in my benchmark.
5760 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

5840 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
5842 Revert the FOLLOW-SYMLINKS change for file-attributes.
5843 Doing it right would require several changes to Tramp, and there's
5844 not enough time to get that tested before the freeze today.
5845 * dired.c (directory_files_internal, Ffile_attributes):
5848 * frame.c (x_report_frame_params): Port better to wider ints.
5849 Do not assume that EMACS_UINT is the same width as uprintmax_t,
5850 or that pointers can be printed in 15 decimal digits.
5851 Avoid GCC warnings if EMACS_UINT is wider than a pointer.

5887 * vm-limit.c (lim_data): Now size_t.
5888 (check_memory_limits): Adjust prototypes of real_morecore and
5889 __morecore to receive argument of type ptrdiff_t. Use size_t for

5969 * xdisp.c (start_hourglass, cancel_hourglass): Now used on
5971 (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
5973 * w32.h (init_timers, term_timers): Add prototypes.
5975 2012-09-30 Kenichi Handa <handa@gnu.org>
5977 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
5978 to the buffer relocation which may be caused by ccl_driver.

6009 fullscreen. Set maximized_width/height. Act on next_maximized.
6011 * nsterm.h (MAC_OS_X_VERSION_10_7, MAC_OS_X_VERSION_10_8): New.
6012 (EmacsView): Add variables for fullscreen.
6013 (handleFS, setFSValue, toggleFullScreen): New in EmacsView.
6014 (EmacsFSWindow): New interface for fullscreen.
6016 2012-09-30 Juanma Barranquero <lekktu@gmail.com>
6018 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
6020 2012-09-30 Chong Yidong <cyd@gnu.org>
6022 * fns.c (Frandom): Doc fix.
6024 2012-09-30 Martin Rudalics <rudalics@gmx.at>
6026 * window.c (Vwindow_combination_limit): New default value.
6027 (Qwindow_size): New symbol replacing Qtemp_buffer_resize.
6029 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
6031 * syssignal.h (PROFILER_CPU_SUPPORT): Don't define if PROFILING.
6032 Suggested by Eli Zaretskii in
6033 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
6035 2012-09-30 Eli Zaretskii <eliz@gnu.org>
6037 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
6038 HAVE_TIMER_SETTIME is defined.
6040 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
6042 Profiler improvements: more-accurate timers, overflow checks.
6043 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
6044 signal.h, setjmp.h. Include systime.h instead.
6045 (saturated_add): New function.
6046 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.
6047 (record_backtrace, handle_profiler_signal): Saturate on fixnum overflow.
6048 (profiler_timer, profiler_timer_ok) [HAVE_TIMER_SETTIME]:
6050 (enum profiler_cpu_running): New enum.
6051 (profiler_cpu_running): Now of that enum type, not bool.
6052 All uses changed to store the new value.
6053 (handle_profiler_signal): Rename from sigprof_handler_1,
6054 for consistency with other handlers. Do not check whether
6055 cpu_log is a hash-table if garbage collecting, since it
6056 doesn't matter in that case.
6057 (deliver_profiler_signal): Rename from sigprof_handler,
6058 for consistency with other handlers.
6059 (setup_cpu_timer): New function, with much of what used to be in
6060 Fprofiler_cpu_start. Check for out-of-range argument.
6061 Prefer timer_settime if available, and prefer
6062 thread cputime clocks, then process cputime clocks, then
6063 monotonic clocks, to the old realtime clock. Use make_timeval
6064 to round more-correctly when falling back to setitimer.
6065 (Fprofiler_cpu_start): Use it.
6066 (Fprofiler_cpu_stop): Prefer timer_settime if available.
6067 Don't assume that passing NULL as the 2nd argument of setitimer
6068 is the same as passing a pointer to all-zero storage.
6069 Ignore SIGPROF afterwards.
6070 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
6071 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
6072 non-fatal signal handlers. Ignore SIGPROF on startup.
6073 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
6074 in profiler.c, since sysdep.c now uses it.
6076 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
6077 Suggested by Eli Zaretskii in
6078 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

6100 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
6101 Qautomatic_redisplay and change the symbol name. All users changed.

6128 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
6130 * character.h (MAYBE_UNIFY_CHAR): Remove.
6131 * charset.c, charset.h (maybe_unify_char): Now static.
6132 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6133 Since this stuff is now private to charset.c, there's no need for
6134 a public macro and no need to inline by hand.

6167 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
6169 Prefer POSIX timers if available.
6170 They avoid a race if the timer is too close to the current time.
6171 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
6172 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

6175 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6177 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
6178 CHAR_STRING_ADVANCE.

6196 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
6198 * w32.h (Vlibrary_cache): Do not declare.
6200 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6202 * w32proc.c (sys_signal): Handle all signals defined by the
6203 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6204 handlers for signals supported by Windows. Don't override
6205 term_ntproc as the handler for SIGABRT.
6206 (sigaction): Rewrite to call sys_signal instead of duplicating its
6208 (sys_kill): Improve commentary.
6210 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6211 consistency with a signature of a signal handler. All callers
6213 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6214 install term_ntproc as a signal handler for SIGABRT, as that
6215 should be done by the dumped Emacs.
6217 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6219 * w32select.c (term_w32select): Protect against repeated
6220 invocation by setting clipboard_owner to NULL after calling
6223 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
6224 and term_ntproc to their modified signatures.
6226 * character.c (char_string, string_char): Remove calls to
6227 MAYBE_UNIFY_CHAR. See the discussion starting at

6235 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6237 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6238 when encountering an unknown bytecode.
6240 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6242 image.c, indent.c: Use bool for booleans.
6243 * dispextern.h (struct image_type): Members valid_p, load, init

6245 * image.c: Omit unnecessary static decls.
6246 (x_create_bitmap_mask, x_build_heuristic_mask):

6284 Move pid_t related decls out of lisp.h.
6285 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6286 (interruptible_wait_for_termination):
6287 Move these decls from lisp.h to syswait.h, since they use pid_t.
6288 Needed on FreeBSD; see Herbert J. Skuhra in
6289 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6290 * callproc.c: Include syswait.h.

6336 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6338 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6339 fatal_error_backtrace.
6341 * w32proc.c (sys_kill): Undo last change: don't do anything when
6342 invoked to deliver SIGABRT to our own process. This is now
6343 handled by emacs_raise.
6345 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6347 * w32term.c (w32_read_socket): Remove leftover reference to
6348 interrupt_input_pending.
6350 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6352 Do not use SA_NODEFER.
6353 Problem reported by Dani Moncayo in
6354 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6356 * sysdep.c (emacs_abort): Do not reset signal handler.
6357 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6358 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6359 wanted even on POSIXish hosts, and it doesn't work on Windows.
6361 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6363 * xterm.c (x_term_init): Call fixup_locale before and after calling
6364 gtk_init (Bug#12392).
6366 2012-09-23 Chong Yidong <cyd@gnu.org>
6368 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6369 Vdynamic_library_alist.
6371 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6372 (Fgnutls_available_p): Caller changed.
6374 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6375 (Flibxml_parse_xml_region): Likewise.
6377 * dispextern.h (struct image_type): Remove arg from init function.
6379 * image.c (Finit_image_library, lookup_image_type)
6380 (define_image_type): Remove now-unneeded second arg.
6381 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6382 (init_tiff_functions, init_gif_functions, init_svg_functions):
6383 Arglist and w32_delayed_load calling convention changed.
6384 (gs_type): Remove init_gs_functions; there is no such function.
6385 (valid_image_p, make_image): Fix caller to lookup_image_type.
6387 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6389 Simplify and avoid signal-handling races (Bug#12471).
6391 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6392 Avoid recursive loop if there's a fatal error in the function itself.
6393 * atimer.c (pending_atimers):
6394 * blockinput.h: Don't include "atimer.h"; no longer needed.
6395 (interrupt_input_pending): Remove. All uses removed.
6396 pending_signals now counts both atimers and ordinary interrupts.
6397 This is less racy than having three separate pending-signal flags.
6398 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6400 Rename from their upper-case counterparts BLOCK_INPUT,
6401 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6402 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6403 This makes it easier to access volatile variables more accurately.
6404 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6405 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6406 that's more reliable if the code is buggy and sets
6407 interrupt_input_blocked to a negative value. All uses changed.
6408 * atimer.c (deliver_alarm_signal):
6409 Remove. No need to deliver this to the parent; any thread can
6410 handle this signal now. All uses replaced by underlying handler.
6411 * atimer.c (turn_on_atimers):
6412 * dispnew.c (handle_window_change_signal):
6413 * emacs.c (handle_danger_signal):
6414 * keyboard.c (kbd_buffer_get_event):
6415 Don't reestablish signal handler; not needed with sigaction.
6416 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6418 Rework to avoid unnecessary accesses to volatile variables.
6419 (UNBLOCK_INPUT_TO): Now a function.
6420 (totally_unblock_input, unblock_input): New decls.
6421 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6422 (init_data): Remove. Necessary stuff now done in init_signal.
6423 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6424 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6425 (fatal_error_code): Remove; no longer needed.
6426 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6427 it doesn't always backtrace. All uses changed. No need to reset
6428 signal to default, since sigaction and/or die does that for us now.
6429 Use emacs_raise (FOO), not kill (getpid (), FOO).
6430 (main): Check more-accurately whether we're dumping.
6431 Move fatal-error setup to sysdep.c
6432 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6433 * gtkutil.c (xg_get_file_name, xg_get_font):
6434 Remove no-longer-needed signal-mask manipulation.
6435 * keyboard.c, process.c (POLL_FOR_INPUT):
6436 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6437 * keyboard.c (read_avail_input): Remove.
6438 All uses replaced by gobble_input.
6439 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6440 (kbd_buffer_store_event_hold, gobble_input):
6441 (record_asynch_buffer_change) [USABLE_SIGIO]:
6442 (store_user_signal_events):
6443 No need to mess with signal mask.
6444 (gobble_input): If blocking input and there are terminals, simply
6445 set pending_signals to 1 and return. All hooks changed to not
6446 worry about whether input is blocked.
6447 (process_pending_signals): Clear pending_signals before processing
6448 them, in case a signal comes in while we're processing.
6449 By convention callers now test pending_signals before calling us.
6450 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6451 New functions, to support changes to blockinput.h.
6452 (handle_input_available_signal): Now extern.
6453 (reinvoke_input_signal): Remove. All uses replaced by
6455 (quit_count): Now volatile, since a signal handler uses it.
6456 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6457 All callers changed. Block SIGINT only if not already blocked.
6458 Clear sigmask reliably, even if Fsignal returns, which it can.
6459 Omit unnecessary accesses to volatile var.
6460 (quit_throw_to_read_char): No need to restore sigmask.
6461 * keyboard.c (gobble_input, handle_user_signal):
6462 * process.c (wait_reading_process_output):
6463 Call signal-handling code rather than killing ourselves.
6464 * lisp.h: Include <float.h>, for...
6465 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6466 (pending_signals): Now volatile.
6467 (syms_of_data): Now const if IEEE floating point.
6468 (handle_input_available_signal) [USABLE_SIGIO]:
6469 (terminate_due_to_signal, record_child_status_change): New decls.
6470 * process.c (create_process): Avoid disaster if memory is exhausted
6471 while we're processing a vfork, by tightening the critical section
6473 (send_process_frame, process_sent_to, handle_pipe_signal)
6474 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6476 (send_process): No need for setjmp/longjmp any more, since the
6477 SIGPIPE stuff is now gone. Instead, report an error if errno
6479 (record_child_status_change): Now extern. PID and W are now args.
6480 Return void, not bool. All callers changed.
6481 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6482 Remove. All uses removed. This bug should be fixed now in a
6484 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6485 and record the child status change directly. This avoids the
6486 need to futz with the signal mask.
6487 (process_fatal_action): Move here from emacs.c.
6488 (emacs_sigaction_flags): New function, containing
6489 much of what used to be in emacs_sigaction_init.
6490 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6491 caught by emacs, to make races less likely.
6492 (deliver_process_signal): Rename from handle_on_main_thread.
6494 (BACKTRACE_LIMIT_MAX): Now at top level.
6495 (thread_backtrace_buffer, threadback_backtrace_pointers):
6497 (deliver_thread_signal, deliver_fatal_thread_signal):
6498 New functions, for more-accurate delivery of thread-specific signals.
6499 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6500 (deliver_arith_signal): Handle in this thread, not
6501 in the main thread, since it's triggered by this thread.
6502 (maybe_fatal_sig): New function.
6503 (init_signals): New arg DUMPING so that we can be more accurate
6504 about whether we're dumping. Caller changed.
6505 Treat thread-specific signals differently from process-general signals.
6506 Block all signals while handling fatal error; that's safer.
6507 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6509 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6510 Ignore SIGPIPE unless batch.
6511 (emacs_backtrace): Output backtrace for the appropriate thread,
6512 which is not necessarily the main thread.
6513 * syssignal.h: Include <stdbool.h>.
6514 (emacs_raise): New macro.
6515 * xterm.c (x_connection_signal): Remove; no longer needed
6516 now that we use sigaction.
6517 (x_connection_closed): No need to mess with sigmask now.
6518 (x_initialize): No need to reset SIGPIPE handler here, since
6519 init_signals does this for us now.
6521 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6523 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6524 background rect may be larger (Bug#12245).
6526 2012-09-23 Chong Yidong <cyd@gnu.org>
6528 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6530 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6532 * .gdbinit: Just stop at fatal_error_backtrace.
6533 See Stefan Monnier's request in
6534 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6535 Remove no-longer-used query of system type.
6537 2012-09-22 Chong Yidong <cyd@gnu.org>
6539 * search.c (Freplace_match): Doc fix (Bug#12325).
6541 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6543 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6544 (Fline_end_position): Doc fix.
6546 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6548 2012-09-22 Chong Yidong <cyd@gnu.org>
6550 * dispextern.h (struct image_type): Add new slot, storing a type
6551 initialization function.
6553 * image.c (define_image_type): Call the image initializer function
6554 if it is defined. Arguments and return value changed.
6555 (valid_image_p, make_image): Callers changed.
6556 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6557 (gif_type, imagemagick_type, svg_type, gs_type):
6558 Add initialization functions.
6559 (Finit_image_library): Call lookup_image_type.
6560 (CHECK_LIB_AVAILABLE): Macro deleted.
6561 (lookup_image_type): Call define_image_type here, rather than via
6562 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6563 (syms_of_image): Move define_image_type calls for xbm_type and
6564 pbm_type to lookup_image_type.
6566 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6568 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6569 'idle_timers' from here ...
6570 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6571 lists, to avoid infloops when the timer does something stupid,
6572 like reinvoke itself with the same or smaller time-out.
6575 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6577 * window.c (Fsplit_window_internal): Handle only Qt value of
6578 Vwindow_combination_limit separately.
6579 (Qtemp_buffer_resize): New symbol.
6580 (Vwindow_combination_limit): New default value.
6583 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6585 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6586 the new overlay string. (Bug#10159)
6588 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6590 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6591 or that fprintf is async-signal-safe. POSIX doesn't require
6594 2012-09-22 Chong Yidong <cyd@gnu.org>
6596 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6599 2012-09-22 Kenichi Handa <handa@gnu.org>
6601 * composite.c (composition_reseat_it): Handle the case that a
6602 grapheme cluster is not covered by a single font (Bug#12352).
6604 2012-09-21 Chong Yidong <cyd@gnu.org>
6606 * image.c (define_image_type): Avoid adding duplicate types to
6607 image_types (Bug#12463). Suggested by Jörg Walter.
6609 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6611 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6612 (print_load_command_name): Add case LC_DATA_IN_CODE.
6613 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6615 2012-09-21 Glenn Morris <rgm@gnu.org>
6617 * eval.c (Frun_hook_with_args_until_success)
6618 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6620 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6622 * fileio.c (Ffile_selinux_context): Only call freecon when
6623 lgetfilecon succeeded.
6624 (Fset_file_selinux_context): Likewise. (Bug#12444)
6626 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6628 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6629 reordering, locate the cursor by calling set_cursor_from_row; if
6630 that fails, clear the desired glyph matrix before returning a
6631 failure indication to the caller. Fixes leaving garbled display
6632 when fast scrolling with a down-key. (Bug#12403)
6633 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6634 scrolling through multibyte text.
6636 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6638 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6639 calling mark_vectorlike since that's the one that marks the window.
6640 (mark_discard_killed_buffers): Mark the final cdr.
6641 * window.h (struct window): Move prev/next_buffers to the
6642 non-standard fields.
6643 * window.c (make_window): Initialize prev/next_buffers manually.
6645 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6647 Omit unused arg EXPECTED from socket hooks.
6648 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6649 * nsterm.m (ns_term_init):
6650 * termhooks.h (struct terminal.read_socket_hook):
6651 * w32inevt.c (w32_console_read_socket):
6652 * w32term.c (w32_read_socket):
6653 * xterm.c (XTread_socket):
6654 Omit unused arg EXPECTED. All callers changed.
6655 (store_user_signal_events): Return void, not int, since callers no
6656 longer care about the return value. All uses changed.
6658 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6660 * w32gui.h (XParseGeometry): Do not declare.
6662 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6664 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6665 Ignore 'expected'. See Eli Zaretskii in
6666 <http://bugs.gnu.org/12471#8> (last line).
6668 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6669 (XParseGeometry): Now static. Substitute extremal values for
6670 values that are out of range.
6672 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6674 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6676 * nsfns.m (XParseGeometry): Remove.
6677 (Fx_create_frame): Call x_set_offset to correctly interpret
6678 top_pos in geometry.
6680 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6681 (Fx_parse_geometry): If there is a space in string, call
6682 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6684 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6686 * search.c (scan_buffer): Use character positions in calls to
6687 region_cache_forward and region_cache_backward, not byte
6688 positions. (Bug#12196)
6690 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6691 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6693 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6694 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6695 emacs_blocked_malloc, now deleted.
6697 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6699 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6700 The workaround was for improving performance on Solaris 2.4, but
6701 is getting in the way now. Emacs will still work if someone is
6702 still running Solaris 2.4 in a museum somewhere; Sun dropped
6703 support for Solaris 2.4 in 2003.
6704 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6705 * process.c (create_process) [HAVE_WORKING_VFORK]:
6706 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6707 since Emacs no longer uses vfork on that platform.
6709 2012-09-17 Glenn Morris <rgm@gnu.org>
6711 * emacs.c: Use COPYRIGHT.
6713 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6715 Remove configure's --without-sync-input option (Bug#12450).
6716 When auditing signal-handling in preparation for cleaning it up,
6717 I found that SYNC_INPUT has race conditions and would be a real
6718 pain to fix. Since it's an undocumented and deprecated
6719 configure-time option, now seems like a good time to remove it.
6720 Also see <http://bugs.gnu.org/11080#16>.
6721 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6722 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6723 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6724 (malloc_hysteresis):
6725 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6726 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6727 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6728 (dont_register_blocks, bytes_used_when_reconsidered)
6729 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6730 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6731 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6732 Remove. All uses removed.
6733 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6734 implementation, one that depends on whether the new macro
6735 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6737 * atimer.c (run_timers, handle_alarm_signal):
6738 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6739 (handle_async_input, process_pending_signals)
6740 (handle_input_available_signal, init_keyboard):
6741 * nsterm.m (ns_read_socket):
6742 * process.c (wait_reading_process_output):
6743 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6744 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6746 * xterm.c (XTread_socket):
6748 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6749 * eval.c (handling_signal): Remove. All uses removed.
6750 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6751 All uses replaced with the SYNC_INPUT version.
6752 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6754 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6757 * font.c (Ffont_shape_gstring): Remove unused local.
6759 2012-09-16 Glenn Morris <rgm@gnu.org>
6761 * Makefile.in (clean): No longer run nextstep's clean.
6763 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6765 (ns-app): Move here from ns.mk, and simplify.
6766 (clean): Simplify nextstep entry.
6767 * ns.mk: Remove file.
6769 2012-09-17 Kenichi Handa <handa@gnu.org>
6771 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6772 not covert the last few charactes.
6774 2012-09-16 Kenichi Handa <handa@gnu.org>
6776 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6777 here, but just check the validity of glyphs in the glyph-string.
6779 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6781 * window.c (Fwindow_parameter, Fset_window_parameter):
6782 Accept any window as argument (Bug#12452).
6784 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6786 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6787 to ns_term_init to avoid memory leak.
6789 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6790 explicit retain/release.
6791 (ns_term_init): Only allow one display. Initialize outerpool and
6794 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6796 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6797 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6798 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6799 the Microsoft problem in a different way, by altering ../nt/config.nt.
6801 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6816 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6817 by lisp.h. This completes removal of setjmp.h inclusion
6818 erroneously announced in the previous commit. (Bug#12446)
6820 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6823 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6824 not defined as a macro. The latter happens on MS-Windows.
6827 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6829 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6830 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6831 Some instances of '#include <setjmp.h>' removed, if the
6832 only reason for the instance was because "lisp.h" was included.
6833 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6834 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6835 and _longjmp with the new symbols. Emacs already uses _setjmp if
6836 available, so this change affects only POSIXish hosts that have
6837 sigsetjmp but not _setjmp, such as some versions of Solaris and
6838 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6839 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6840 (png_load_body) [HAVE_PNG]:
6841 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6842 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6843 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6844 since PNG requires jmp_buf. This is the only exception to the
6845 general rule that we now use sys_setjmp and sys_longjmp.
6846 This exception is OK since this code does not change the signal
6847 mask or longjmp out of a signal handler.
6849 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6851 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6852 Include "syssignal.h", for 'main_thread'.
6854 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6856 Avoid out-of-range marker position (Bug#12426).
6857 * insdel.c (replace_range, replace_range_2):
6858 Adjust markers before overlays, as suggested by comments.
6859 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6860 Remove redundant check before calling offset_intervals.
6862 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6864 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6865 current buffer (Bug#12387).
6867 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6869 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6871 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6873 Use a more backwards-compatible timer format (Bug#12430).
6874 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6875 vector element, not from the 4th, since PSECS is now at the end.
6876 (Fcurrent_idle_time): Doc fix.
6878 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6880 Function to mark objects and remove killed buffers at once.
6881 * alloc.c (discard_killed_buffers): Rename to ...
6882 (mark_discard_killed buffers) ... new name. Add marking
6883 of remaining objects. Fix comment. Adjust users.
6884 (mark_object): Do not touch frame buffer lists here.
6885 * frame.c (delete_frame): Reset frame buffer lists here.
6887 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6889 Better workaround for GNOME bug when --enable-gcc-warnings.
6890 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6891 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6892 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6894 Simplify SIGIO usage (Bug#12408).
6895 The code that dealt with SIGIO was crufty and confusing, e.g., it
6896 played tricks like "#undef SIGIO" but these tricks were not used
6897 consistently. Simplify mostly by not #undeffing standard symbols,
6898 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6899 or not as we please) rather than "defined SIGIO" (standard symbol
6900 that we probably shouldn't #undef).
6901 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6902 Modules that need it can include it.
6903 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6904 * dispextern.h (ignore_sigio): New decl.
6905 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6906 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6907 * emacs.c (shut_down_emacs):
6908 * keyboard.c (kbd_buffer_store_event_hold):
6909 Use ignore_sigio rather than invoking 'signal' directly.
6910 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6912 (FIONREAD, SIGIO): Do not #undef.
6913 (tty_read_avail_input): Use #error rather than a syntax error.
6914 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6915 for I_PIPE, used by SETUP_SLAVE_PTY.
6916 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6917 * sysdep.c (croak): Remove; no longer needed. This bit of
6918 temporary code, with Fred N. Fish's comment that it's temporary,
6919 has been in Emacs since at least 1992!
6920 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6921 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6922 * syssignal.h (croak): Remove decl.
6923 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6924 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6925 now that we're termios-only.
6926 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6927 * term.c (dissociate_if_controlling_tty): Use #error rather than
6930 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6931 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6932 to work around GNOME bug 683906.
6933 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6934 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6935 This works around GCC bug 54561.
6937 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6939 More fixes for 'volatile' and setjmp/longjmp.
6940 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6941 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6942 (png_load_body) [HAVE_PNG]:
6943 (jpeg_load_body) [HAVE_JPEG]:
6944 New function, with most of the old parent function's body.
6945 (png_load) [HAVE_PNG]:
6946 (jpeg_load) [HAVE_JPEG]:
6947 Invoke the new function, to avoid longjmp munging our locals.
6948 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6949 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6950 longjmp is passed 2, as the C standard doesn't guarantee this.
6951 Instead, store the failure code into mgr->failure_code.
6953 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6955 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6956 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6957 (syms_of_keyboard): Remove support for unread-command-char.
6959 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6961 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6962 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6963 violation. (Bug#12426)
6965 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6967 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6969 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6971 * eval.c: Add `inhibit-debugger'.
6972 (Qinhibit_debugger): New symbol.
6973 (call_debugger): Bind it instead of Qdebug_on_error.
6974 (maybe_call_debugger): Test Vinhibit_debugger.
6975 (syms_of_eval): Define inhibit-debugger.
6976 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6977 (syms_of_xdisp): Remove inhibit-debug-on-message.
6979 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6981 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6982 If a nonvolatile local variable is written before a _longjmp to
6983 the frame containing the variable, and is read after the _longjmp,
6984 the value read is indeterminate. Some local variables of type
6985 'struct handler' and 'struct catchtag' are used in this way, so
6986 mark each of their slots as volatile if the slot can be set before
6987 _longjmp and read afterwards.
6988 * lisp.h (struct handler): var and chosen_clause are now volatile.
6989 (struct catchtag): val, next, and pdlcount are now volatile.
6991 * bidi.c (bidi_push_it, bidi_pop_it):
6992 * fns.c (copy_hash_table):
6993 * image.c (define_image_type):
6994 * keyboard.c (kbd_buffer_store_event_hold):
6995 * process.c (Fprocess_send_eof):
6996 * xfaces.c (x_create_gc) [HAVE_NS]:
6997 * xgselect.c (xg_select):
6998 Prefer assignment to memcpy when either will do.
7000 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
7001 Use pointer-to-a-pointer to simplify and avoid a NILP check each
7002 time an item is removed. No need to mark this function 'inline';
7003 the compiler knows better than we do.
7005 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
7007 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
7008 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
7009 to change_frame_size (Bug#12388).
7010 (windowDidResize:): Pass YES to updateFrameSize.
7012 * nsterm.h: Add delay parameter to updateFrameSize.
7014 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7016 Discard killed buffers from deleted window and frame objects.
7017 This reduces an amount of references to killed buffers and
7018 helps GC to reclaim them faster.
7019 * alloc.c (discard_killed_buffers): New function.
7020 (mark_object): Use it for deleted windows and frames.
7021 (mark_object): If symbol's value is set up for a killed buffer
7022 or deleted frame, restore its global binding.
7023 * data.c (swap_in_global_binding): Add GC notice.
7024 (swap_in_symval_forwarding): Use convenient set_blv_where.
7025 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
7026 * window.h: ... to here.
7028 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
7030 Convenient macro to check whether the buffer is live.
7031 * buffer.h (BUFFER_LIVE_P): New macro.
7032 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
7033 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
7035 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7037 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
7038 composition cases (Bug#12364).
7040 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
7041 overhang of succeeding glyphs overlapping box cursor.
7043 * w32term.c (x_draw_glyph_string): Likewise.
7045 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
7047 Simplify, document, and port floating-point (Bug#12381).
7048 The porting part of this patch fixes bugs on non-IEEE platforms
7049 with frexp, ldexp, logb.
7050 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
7052 * floatfns.c: Simplify discussion of functions that Emacs doesn't
7053 support, by removing commented-out code and briefly listing the
7054 C89 functions excluded. The commented-out stuff was confusing
7055 maintenance, e.g., we thought we needed cbrt but it was commented out.
7056 (logb): Remove decl; no longer needed.
7057 (isfinite): New macro, if not already supplied.
7058 (isnan): Don't replace any existing macro.
7059 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
7060 are present on all C89 platforms.
7061 (Ffrexp): Do not special-case zero, as frexp does the right thing
7063 (Flogb): Do not use logb, as it doesn't have the desired meaning
7064 on hosts that use non-base-2 floating point. Instead, stick with
7065 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
7066 frexp, to avoid getting an unspecified result.
7068 * xdisp.c (Qinhibit_debug_on_message): Now static.
7070 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
7072 * nsterm.m (ns_update_begin): Set clip path to whole view by using
7073 NSBezierPath (Bug#12131).
7075 2012-09-10 Chong Yidong <cyd@gnu.org>
7077 * fns.c (Fdelq, Fdelete): Doc fix.
7079 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7081 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7082 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7084 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7086 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7087 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7090 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7092 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7093 left fringe if the window has a left margin. This avoids leaving
7094 traces of the cursor because its leftmost pixel is not drawn over.
7096 * dispnew.c (update_window_line): When the left margin area of a
7097 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7098 that screen line. (Bug#12277)
7100 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7102 Assume C89 or later for math functions (Bug#12381).
7103 This simplifies the code, and makes it a bit smaller and faster,
7104 and (most important) makes it easier to clean up signal handling
7105 since we can stop worring about floating-point exceptions in
7106 library code. That was a problem before C89, but the problem
7107 went away many years ago on all practical Emacs targets.
7108 * data.c, image.c, lread.c, print.c:
7109 Don't include <math.h>; no longer needed.
7110 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7111 might be autoconfigured, as that never happens.
7113 * doprnt.c (DBL_MAX_10_EXP):
7114 * print.c (DBL_DIG):
7115 Remove. C89 or later always defines these.
7116 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7117 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7118 (arith_error, domain_error, domain_error2):
7119 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7120 no longer needed -- we simply return what C returns. All uses removed.
7121 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7123 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7124 Remove. All uses expanded, as these macros are no longer used
7125 more than once and are now more trouble than they're worth.
7126 (Ftan): Use tan, not sin / cos.
7127 (Flogb): Assume C89 frexp.
7128 (fmod_float): Assume C89 fmod.
7129 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7130 (init_floatfns): Remove. All uses removed.
7132 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7134 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7135 compositeToPoint for OSX < 10.6 (Bug#12390).
7137 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7139 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7140 This produces more-accurate results.
7142 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7144 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7145 changes (Bug#12088).
7147 2012-09-08 Chong Yidong <cyd@gnu.org>
7149 * syntax.c (Fstring_to_syntax): Doc fix.
7151 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7153 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7154 in the internal border.
7155 (x_set_window_size): Remove static variables and their usage.
7156 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7157 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7158 Remove fringe/internal border adjustment (Bug#11052).
7159 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7160 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7161 (ns_fix_rect_ibw): Remove.
7162 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7163 (ns_dumpglyphs_box_or_relief): Ditto.
7164 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7166 (ns_dumpglyphs_image): Ditto.
7167 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7169 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7170 their usage. Add fringe_extended_p and its use as in other terms.
7171 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7172 scroll bar was removed.
7173 (updateFrameSize): New function.
7174 (windowDidResize): Move code to updateFrameSize and call it.
7176 * nsterm.h (EmacsView): Add updateFrameSize.
7178 2012-09-07 Chong Yidong <cyd@gnu.org>
7180 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7182 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7184 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7186 More signal-handler cleanup (Bug#12327).
7187 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7188 Problem introduced when merging patches. Noted by Eli Zaretskii in
7189 <http://bugs.gnu.org/12327#67>.
7190 * floatfns.c: Comment fix.
7191 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7192 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7193 and anyway the declaration is harmless even if SIGDANGER is not defined.
7194 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7195 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7196 source files not surprisingly expected syssignal.h to define, or
7197 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7198 Include <sys/ioctl.h>, for FIONREAD.
7199 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7200 This eliminates a problem whereby other files mysteriously had
7201 to include "syssignal.h" before including "systty.h" if they
7202 wanted to use "#ifdef SIGIO".
7204 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7206 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7208 * w32.c (sigemptyset): Empty the set.
7209 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7211 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7213 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7215 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7216 (mark_object): Likewise for frame objects.
7218 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7220 * syssignal.h (handle_on_main_thread): Always declare,
7221 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7222 This ports to platforms without HAVE_PTHREAD.
7224 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7226 Signal-handler cleanup (Bug#12327).
7227 Emacs's signal handlers were written in the old 4.2BSD style with
7228 sigblock and sigmask and so forth, and this led to some
7229 inefficiencies and confusion. Rewrite these to use
7230 pthread_sigmask etc. without copying signal sets around. Also,
7231 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7232 'signal', and instead use functions that do not attempt to take
7233 over the system name space. This patch causes Emacs's text
7234 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7235 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7236 Do not include <signal.h> or "syssignal.h", as these
7237 modules do not use signals.
7238 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7239 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7240 Do not include <signal.h>, as "syssignal.h" does that for us now.
7241 * atimer.c (sigmask_atimers): New function.
7242 (block_atimers, unblock_atimers): New functions,
7243 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7245 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7246 no longer needed here.
7247 * emacs.c (main): Inspect existing signal handler with sigaction,
7248 so that there's no need to block and unblock SIGHUP.
7249 * sysdep.c (struct save_signal): New member 'action', replacing
7250 old member 'handler'.
7251 (save_signal_handlers, restore_signal_handlers):
7252 Use sigaction instead of 'signal' to save and restore.
7253 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7254 New function. All users of 'signal' modified to use set_sighandler
7255 if they're writeonly, and to use sys_signal if they're read+write.
7256 (emacs_sigaction_init, forwarded_signal): New functions.
7257 (sys_signal): Remove. All uses replaced by calls to sigaction
7258 and emacs_sigaction_init, or by direct calls to 'signal'.
7259 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7260 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7261 all uses replaced by pthread_sigmask etc. calls.
7262 * syssignal.h: Include <signal.h>.
7263 (emacs_sigaction_init, forwarded_signal): New decls.
7264 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7265 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7266 (sigmask, sys_sigmask): Remove; no longer needed.
7267 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7268 (sigblock, sigunblock, sigfree):
7269 (sigsetmask) [!defined sigsetmask]:
7270 Remove. All uses replaced by pthread_sigmask.
7271 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7272 no longer need to be replaced, and its typical old uses
7273 are now done via emacs_sigaction_init and sigaction.
7274 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7275 (sys_sigdel): Remove; unused.
7276 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7278 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7280 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7281 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7283 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7285 Explicitly mark buffer_defaults and buffer_local_symbols.
7286 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7287 mark_local_symbols here.
7288 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7289 since special buffers aren't marked here any more.
7290 (allocate_buffer): Chain new buffer with all_buffers here...
7291 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7293 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7294 (syms_of_buffer): Remove staticpro of the above.
7295 (init_buffer_once): Set names for buffer_defaults and
7296 buffer_local_symbols.
7298 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7300 Use bool for booleans in font-related modules.
7301 * font.c (font_intern_prop, font_style_to_value)
7302 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7303 (generate_otf_features, font_check_otf_features, font_check_otf)
7304 (font_match_p, font_list_entities, font_at):
7305 * fontset.c (fontset_id_valid_p, reorder_font_vector
7306 (fontset_find_font, Fset_fontset_font)
7307 (face_suitable_for_char_p) [0]:
7308 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7309 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7310 (m17n_flt_initialized, ftfont_shape_by_flt):
7311 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7312 * nsfont.m (nsfont_draw):
7313 * w32font.c (w32font_draw):
7314 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7315 Use bool for booleans.
7316 * font.h: Adjust to above API changes.
7317 (struct font, struct font_driver, struct font_driver_list):
7318 Use bool for booleans.
7319 (struct font): Remove useless member encoding_type.
7321 * fontset.c, xftfont.c: Omit unnecessary static decls.
7323 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7325 * alloc.c (mark_object): Revert window marking code
7326 since it's unsafe for the Fset_window_configuration.
7328 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7330 Fix race conditions with signal handlers and errno (Bug#12327).
7331 Be more systematic about preserving errno whenever a signal
7332 handler returns, even if it's not in the main thread. Do this by
7333 renaming signal handlers to distinguish between signal delivery
7334 and signal handling. All uses changed.
7335 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7336 * data.c (deliver_arith_signal): Rename from arith_error.
7337 * dispnew.c (deliver_window_change_signal): Rename from
7338 window_change_signal.
7339 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7340 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7341 * keyboard.c (deliver_input_available_signal): Rename from
7342 input_available_signal.
7343 (deliver_user_signal): Rename from handle_user_signal.
7344 (deliver_interrupt_signal): Rename from interrupt_signal.
7345 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7346 (deliver_child_signal): Rename from sigchld_handler.
7347 * atimer.c (handle_alarm_signal):
7348 * data.c (handle_arith_signal):
7349 * dispnew.c (handle_window_change_signal):
7350 * emacs.c (handle_fatal_signal, handle_danger_signal):
7351 * keyboard.c (handle_input_available_signal):
7352 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7353 * process.c (handle_pipe_signal, handle_child_signal):
7354 New functions, with the actual signal-handling code taken from the
7355 original respective signal handlers, sans the sporadic attempts to
7356 preserve errno, since that's now done by handle_on_main_thread.
7357 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7358 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7359 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7361 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7362 Move initialization of main_thread to sysdep.c's init_signals.
7363 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7364 our usage, and simplifies the mainline code.
7365 (record_child_status_change): New static function, as a helper
7366 for handle_child_signal, and with most of the old child handler's
7368 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7369 (handle_child_signal): Use the above.
7370 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7371 Moved here from emacs.c.
7372 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7373 code moved here from emacs.c's main function.
7374 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7375 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7376 This lets callers save and restore errno properly.
7378 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7380 Remove redundant or unused things here and there.
7381 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7382 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7383 * editfns.c (Fcompare_buffer_substrings): Likewise.
7384 * frame.h (struct terminal, struct font_driver_list):
7385 Remove redundant declarations.
7386 * window.h (Qleft, Qright): Likewise.
7388 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7390 Do not mark objects from deleted buffers, windows and frames.
7391 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7392 (mark_object): Likewise for windows and frames.
7394 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7396 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7397 buffer_defaults and buffer_local_symbols as valid objects.
7398 Return special value to denote them.
7400 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7402 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7403 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7404 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7405 (file_name_absolute_p, Fsubstitute_in_file_name):
7406 (check_executable, check_writable, Ffile_accessible_directory_p)
7407 (Fset_file_selinux_context, Fdefault_file_modes)
7408 (Finsert_file_contents, choose_write_coding_system)
7409 (Fwrite_region, build_annotations, a_write, e_write)
7411 * filelock.c (boot_time_initialized, get_boot_time)
7412 (get_boot_time_1, lock_file_1, within_one_second):
7413 * floatfns.c (in_float):
7414 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7415 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7416 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7417 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7418 * window.c (compare_window_configurations):
7419 Use bool for booleans.
7420 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7421 (Fdefault_file_modes): Now mode_t, not int, for modes.
7422 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7423 (internal_delete_file): Now returns void, not a (boolean) int,
7424 since nobody was looking at the return value.
7425 * lisp.h, window.h: Adjust to above API changes.
7427 * xdisp.c (set_message): Simplify and reindent last change.
7429 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7431 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7433 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7435 * eval.c (call_debugger): Make the function non-static so that we
7436 can call it from set_message.
7438 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7439 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7441 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7443 Give more-useful info on a fatal error (Bug#12328).
7444 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7445 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7446 of doing the work ourselves.
7447 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7448 do most of the work.
7449 (fatal_error_backtrace): New function, taken from the guts
7450 of the old fatal_error_signal, but with a new option to output
7452 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7453 info about the signal than just its number.
7454 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7455 * sysdep.c: Include <execinfo.h>
7456 (emacs_backtrace): New function, taken partly from the previous
7457 code of the 'die' function.
7458 (emacs_abort): Call fatal_error_backtrace rather than abort.
7460 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7462 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7463 eager (load-time) macro-expansion.
7464 * lisp.mk (lisp): Add macroexp.
7466 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7468 Simplify redefinition of 'abort' (Bug#12316).
7469 Do not try to redefine the 'abort' function. Instead, redo
7470 the code so that it calls 'emacs_abort' rather than 'abort'.
7471 This removes the need for the NO_ABORT configure-time macro
7472 and makes it easier to change the abort code to do a backtrace.
7473 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7474 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7475 Remove; sysdep.c's emacs_abort now takes its place.
7476 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7477 'abort' changed to use 'emacs_abort'.
7478 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7479 (abort) [!defined abort]: Rename to ...
7480 (emacs_abort): ... new name.
7481 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7482 the place of the old 'abort' in emacs.c.
7483 * w32.c, w32fns.c (abort): Do not #undef.
7484 * w32.c (emacs_abort): Rename from w32_abort.
7486 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7488 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7489 offsets[j].dv, since the y axis of the screen coordinates points
7490 down, while the y axis of the font definition coordinates points
7491 up. This fixes display of Arabic diacritics such as KASRA and
7492 KASRATAN. (Bug#11860)
7494 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7496 Be more systematic about _setjmp vs setjmp.
7497 * alloc.c (test_setjmp, mark_stack):
7498 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7499 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7500 (png_load, my_error_exit, jpeg_load):
7501 * process.c (send_process_trap, send_process):
7502 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7503 The underscored versions are up to 30x faster on some hosts.
7504 Formerly, the code used setjmp+longjmp sometimes and
7505 _setjmp+_longjmp at other times, with no particular reason to
7506 prefer setjmp+longjmp.
7508 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7510 Fix minor problem found by static checking.
7511 * buffer.c (Fdelete_all_overlays): Return nil.
7513 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7515 * buffer.c (Fdelete_all_overlays): New function.
7517 2012-09-03 Chong Yidong <cyd@gnu.org>
7519 * gtkutil.c: Add extern decl for Qxft.
7521 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7523 * emacs.c, eval.c: Use bool for boolean.
7524 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
7525 (malloc_using_checking) [DOUG_LEA_MALLOC]:
7526 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
7527 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
7528 (main, decode_env_path, Fdaemon_initialized):
7529 * eval.c (call_debugger, Finteractive_p, interactive_p):
7530 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
7531 (maybe_call_debugger, Fbacktrace):
7532 * process.c (read_process_output, exec_sentinel):
7533 Use bool for booleans.
7534 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
7535 All callers changed.
7536 * eval.c (interactive_p): Omit always-true boolean argument
7537 EXCLUDE_SUBRS_P. All callers changed.
7538 * dispextern.h, lisp.h: Reflect above API changes.
7539 * firstfile.c (dummy): Use the address of 'main', whose signature
7540 won't change, instead of the address of 'initialize', whose
7541 signature just changed from int to bool.
7542 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7543 * msdos.c (fatal_error_in_progress): ... from here.
7544 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7546 (redisplay_internal, unwind_redisplay): Simply clear
7547 REDISPLAYING_P when unwinding, instead of saving its previous,
7548 always-false value and then restoring it.
7550 Clean up some extern decls.
7551 Mostly, this hoists extern decls out of .c files and into .h files.
7552 That way, we're more likely to catch errors if the interfaces change.
7553 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7554 declare xg_mark_data.
7555 * dispextern.h (x_frame_parm_handlers):
7557 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7558 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
7559 (Qultra_bold, Qoblique, Qitalic):
7560 Move extern decl here from .c file.
7561 * alloc.c (xg_mark_data) [USE_GTK]:
7563 * eval.c (Qlexical_binding):
7564 * fns.c (time) [!HAVE_UNISTD_H]:

7571 * widget.c (free_frame_faces):
7572 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
7573 * xfont.c (x_clear_errors):
7574 * xterm.c (x_frame_parm_handlers):
7575 Remove now-redundant extern decls.
7576 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7577 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7579 * xfaces.c: Remove unnecessary static decls.
7580 * xterm.c (updating_frame): Remove decl of nonexistent object.
7582 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7583 when building globals.h, as the objects that are not built on
7584 this host are not needed to compile C files on this host.
7586 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7588 * gtkutil.h: Remove prototype for x_wm_set_size_hint.
7590 * frame.h: Add missing prototype for x_wm_set_size_hint.
7592 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

7596 (Fdocumentation, Fdocumentation_property, Fsnarf_documentation)
7597 (Fsubstitute_command_keys):

7602 (make_buffer_string, make_buffer_string_both)
7603 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

7613 (adjust_for_invis_intang, set_point_both)

7615 (set_intervals_multibyte_1, set_intervals_multibyte):
7616 * keyboard.c (decode_timer):
7617 Use bool for boolean.

7626 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7628 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
7629 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

7634 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
7636 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7638 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7639 more than one grapheme cluster passed to the shaper: compute the
7640 offset adjustment values separately for each cluster. (Bug#11860)
7642 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7643 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7644 about implicit conversions from integer to pointer.
7646 2012-09-01 Daniel Colascione <dancol@dancol.org>
7648 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7649 system used too early.
7651 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7653 Better seed support for (random).
7654 * emacs.c (main): Call init_random.
7655 * fns.c (Frandom): Set the seed from a string argument, if given.
7656 Remove long-obsolete Gentzel cruft.

7666 x_set_menu_bar_lines, x_char_width, x_char_height, x_sync,
7667 x_set_tool_bar_lines, x_activate_menubar, and free_frame_menubar,
7668 all of which have been moved to common code.
7670 * xfaces.c: Include TERM_HEADER instead of listing all possible
7671 window-system headers.
7673 * w32xfns.c (x_sync): Correct definition of x_sync (a no-op here)

7677 directly accessing frame internals.
7679 * w32font.h: Include font.h. Define syms_of_w32font and
7682 * process.c: Include TERM_HEADER instead of listing all possible
7683 window-system headers.
7685 * nsterm.h: Remove declarations now in frame.h.
7686 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
7688 * menu.c: Include TERM_HEADER instead of listing all possible
7689 window-system headers.
7691 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
7694 * keyboard.c: Include TERM_HEADER instead of listing all possible
7695 window-system headers.
7697 * image.c: Include TERM_HEADER instead of listing all possible
7698 window-system headers. Declare Vlibrary_cache when compiling for
7701 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
7702 window system declarations.
7704 * frame.h: Move common functions here: set_frame_menubar,
7705 x_set_window_size, x_sync, x_get_focus_frame,
7706 x_set_mouse_position, x_set_mouse_pixel_position,
7707 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7727 * Makefile.in: Define WINDOW_SYSTEM_OBJ to hold objects needed for
7728 the current window system; include in list of objects to link into
7731 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7733 Remove mark_ttys function and fix tty_display_info initialization.
7734 * lisp.h (mark_ttys): Remove prototype.
7735 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
7736 to mark_ttys because all possible values of 'top_frame' slot are
7737 the frames which are reachable from Vframe_list.
7738 * term.c (mark_ttys): Remove.
7739 (init_tty): Safely initialize 'top_frame' slot with Qnil.
7741 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7743 Change struct frame bitfields from unsigned char to unsigned.
7744 * frame.h (struct frame): Change type of 'display_preempted',
7745 'visible', 'iconified', 'has_minibuffer', 'wants_modeline',
7746 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
7747 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
7748 bitfields from unsigned char to unsigned.
7750 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7752 Remove unused member of struct x_output and struct w32_output.
7753 * xterm.h (struct x_output): Remove unused field 'needs_exposure'.
7754 * w32term.h (struct w32_output): Likewise.
7756 2012-08-30 Jan Djärv <jan.h.d@swipnet.se>
7758 * gtkutil.c (x_wm_set_size_hint): Use 1 col for base_width so it
7759 does not become zero (Bug#12234).
7761 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
7763 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
7764 for GCC 4.7.1 x86-64.
7766 2012-08-30 Glenn Morris <rgm@gnu.org>
7768 * lread.c (init_lread): For out-of-tree builds, only add the
7769 source directory's site-lisp dir to the load-path if it exists,
7770 consistent with in-tree builds. (Bug#12302)
7772 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
7774 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize
7775 button_values to NULL. Call setStykeMask so dialogs get a close button.
7776 (windowShouldClose:): Set window_closed.
7777 (dealloc): New member, free button_values.
7778 (process_dialog:): Make member function. Remove window argument,
7779 replace window with self. Count buttons and allocate and store values
7781 (addButton:value:row:): value is int with the name tag. Call setTag
7782 with tag. Remove return self, declare return value as void.
7783 (addString:row:): Remove return self, declare return value as void.
7784 (addSplit): Remove return self, declare return value as void.
7785 (clicked:): Remove return self, declare return value as void.
7786 Set dialog_return to button_values[seltag]. Code formatting change.
7787 (initFromContents:isQuestion:): Adjust call to process_dialog.
7788 Code formatting change.
7789 (timeout_handler:): Set timer_fired to YES.
7790 (runDialogAt:): Set timer_fired to NO.
7791 Handle click on close button as quit.
7793 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7794 Add window_closed and button_values. Add void as return value for
7795 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7796 Add process_dialog as new member.
7798 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7800 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
7801 is not one of the heaps we manage. (Bug#12242)
7803 2012-08-28 Glenn Morris <rgm@gnu.org>
7805 * eval.c (Fcalled_interactively_p): Doc fix. (Bug#11747)
7807 2012-08-28 Martin Rudalics <rudalics@gmx.at>
7809 * window.c (Fset_window_configuration): Remove handling of
7810 auto-buffer-name window parameter. Install revision of reverted
7813 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7815 Do not allow to set major mode for a dead buffer.
7816 * buffer.c (Fset_buffer_major_mode): Signal an error
7817 if the buffer is dead.
7818 (Fother_buffer, other_buffer_safely): Remove redundant
7821 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7823 Always use set_buffer_if_live to restore original buffer at unwind.
7824 * buffer.h (record_unwind_current_buffer): New function.
7825 * bytecode.c, dispnew.c, editfns.c, fileio.c, fns.c, insdel.c:
7826 * keyboard.c, keymap.c, minibuf.c, print.c, process.c, textprop.c:
7827 * undo.c, window.c: Adjust users.
7828 * buffer.c (set_buffer_if_live): Fix comment.
7830 2012-08-28 Dmitry Antipov <dmantipov@yandex.ru>
7832 Fix usage of set_buffer_internal.
7833 * buffer.h (set_buffer_internal): Make it BUFFER_INLINE.
7834 * buffer.c (set_buffer_if_live): Use set_buffer_internal.
7835 * coding.c (decode_coding): Omit redundant test.
7836 * fileio.c (decide_coding_unwind): Likewise.
7837 * fns.c (secure_hash): Likewise.
7838 * insdel.c (modify_region): Likewise.
7839 * keyboard.c (command_loop_1): Likewise.
7840 * print.c (PRINTFINISH): Likewise.
7841 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
7843 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

7861 (change_frame_size_1, sit_for):
7862 Use bool for boolean.
7863 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
7864 and remove last int (actually boolean) argument, which was always 0.
7865 All callers changed.
7866 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
7867 * dispextern.h (struct composition_it): Use bool for boolean.
7868 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
7869 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
7870 * dired.c (file_name_completion):
7871 Use bool for boolean. (This was missed in an earlier change.)
7873 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7875 * window.c (Fset_window_configuration): Revert first part of
7878 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
7880 * nsterm.h (NSPanel): New class variable dialog_return.
7882 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
7883 Initialize dialog_return.
7884 (windowShouldClose:): Use stop instead of stopModalWithCode.
7885 (clicked:): Ditto, and also set dialog_return (Bug#12258).
7886 (timeout_handler:): Use stop instead of abortModal. Send a dummy
7888 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
7891 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

7903 Use bool for booleans.
7904 * dired.c (file_name_completion):
7905 * process.h (fd_callback):
7906 Omit int (actually boolean) argument. It wasn't being used.
7908 * composite.h, lisp.h: Reflect above API changes.

7932 * fileio.c (Finsert_file_contents):
7933 Use bool for booleans.
7934 * coding.h, lisp.h: Reflect above API changes.
7935 * coding.c: Remove unnecessary static function decls.
7936 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7937 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7938 not a boolean 'int', since callers never look at the return value.
7939 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
7940 * coding.h (decoding_buffer_size, encoding_buffer_size)
7941 (emacs_mule_string_char): Remove unused extern decls.
7942 (struct iso_2022_spec, struct coding_system):
7943 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7944 (struct emacs_mule_spec): Remove unused field 'full_support'.
7945 All initializations removed.
7946 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7948 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7950 Fix spare memory change (Bug#12286).
7951 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7952 (valid_lisp_object_p): Likewise.
7954 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7956 * window.c (Fset_window_configuration): Record any window's old
7957 buffer if it's replaced (see Bug#8789). If the new current
7958 buffer doesn't appear in the selected window, go to its old
7961 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7963 Special MEM_TYPE_SPARE to denote reserved memory.
7964 * alloc.c (enum mem_type): New memory type.
7965 (refill_memory_reserve): Use new type for spare memory.
7966 This prevents live_cons_p and live_string_p from incorrect
7967 detection of uninitialized objects from spare memory as live.
7969 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7972 * Makefile.in (.PHONY): versioclean -> versionclean.
7974 Remove unused external symbols.
7975 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7976 * window.c (Qwindow_valid_p, decode_valid_window):
7977 Now static, not extern.
7978 * data.c (Qinterval): Remove; unused.
7979 (syms_of_data): Do not define 'interval'.
7980 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7981 * window.h (decode_valid_window):
7984 * character.c, charset.c, chartab.c: Use bool for booleans.
7985 * character.c (lisp_string_width, string_count_byte8)

7994 (char_table_set_range, optimize_sub_char_table)
7995 (map_sub_char_table):
7996 Use bool for boolean.
7997 * character.c (str_to_unibyte): Omit last boolean argument; it was
7998 always 0. All callers changed.
7999 * character.h, charset.h: Adjust to match previous changes.
8000 * character.h (char_printable_p): Remove decl of nonexistent function.
8001 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
8002 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
8003 are all boolean, so make them single-bit bitfields.
8005 * lisp.h (ASET): Remove attempt to detect side effects.
8006 It was meant to be temporary and it often doesn't work,
8007 because when IDX has side effects the behavior of IDX==IDX
8008 is undefined. See Stefan Monnier in
8009 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
8011 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
8013 * lisp.h (functionp): New function (extracted from Ffunctionp).
8014 (FUNCTIONP): Use it.
8015 * eval.c (Ffunctionp): Use it.
8017 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8019 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
8020 as that's faster and simpler than static storage. Don't bother
8021 with the g_main_context_query overhead if g_main_context_pending
8022 says no events are pending.
8023 (gfds, gfds_size): Remove these static vars.
8024 (xgselect_initialize): Remove; no longer needed.
8025 All uses and decls removed.
8027 * emacs.c (fatal_error_signal_hook): Remove.
8028 All uses removed. This leftover from old code was always 0.
8030 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
8031 * casefiddle.c (casify_object, casify_region):
8032 * casetab.c (set_case_table):
8033 * category.c, category.h (word_boundary_p):
8034 * category.h (CHAR_HAS_CATEGORY):
8035 Use bool for booleans, instead of int.
8037 2012-08-25 Eli Zaretskii <eliz@gnu.org>
8039 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
8041 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
8043 On assertion failure, print backtrace if available.
8044 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
8045 (die) [ENABLE_CHECKING]: Print a backtrace if available.
8046 * Makefile.in (LIB_EXECINFO): New macro.
8049 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
8050 * bytecode.c (exec_byte_code):
8051 * callint.c (check_mark, Fcall_interactively):
8052 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
8053 (getenv_internal, sync_process_alive, call_process_exited):
8054 * lisp.h (USE_SAFE_ALLOCA):
8055 Use bool for booleans, instead of int.
8056 * lisp.h, process.h: Adjust prototypes to match above changes.
8057 * callint.c (Fcall_interactively): Don't assume the mark's
8058 offset fits in 'int'.
8060 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
8062 * buffer.c, buffer.h: Use bool for boolean.
8063 * buffer.c (reset_buffer_local_variables)

8069 (mmap_enlarge, mmap_set_vars):
8070 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
8071 Use bool for booleans, instead of int.
8072 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
8073 since the 1-or-0 return value is always ignored anyway.
8074 (mmap_initialized_p):
8075 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
8076 * buffer.h, lisp.h: Adjust prototypes to match above changes.
8078 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8080 * bidi.c: Use bool for boolean.
8081 This is a bit more readable, and makes the text segment of bidi.o
8082 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8083 Presumably it's faster too.
8084 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
8086 (bidi_cache_find_level_change, bidi_cache_iterator_state)

8089 (bidi_explicit_dir_char, bidi_level_of_next_char)
8090 (bidi_find_other_level_edge, bidi_move_to_visually_next):
8091 Use bool for booleans, instead of int.
8092 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8093 (bidi_unshelve_cache): Adjust decls to match code.
8095 2012-08-23 Martin Rudalics <rudalics@gmx.at>
8097 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
8100 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8102 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
8103 * atimer.h: Include <stdbool.h>.
8105 2012-08-22 Dan Nicolaescu <dann@gnu.org>
8107 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8108 compile time tests instead of run time tests on systems that do
8110 (FRAME_MAC_P): Remove leftover from deleted code.
8111 * frame.c (syms_of_frame): Remove leftover from deleted code.
8113 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8115 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8117 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8119 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8120 Otherwise, the compiler complains about (A?B:C) where B is void
8121 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8122 (fontset_add): Return void, for FONTSET_ADD.
8124 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8126 * alloc.c: Use bool for booleans.
8127 (gc_in_progress, abort_on_gc)
8128 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8129 (dont_register_blocks) [GC_MALLOC_CHECK]:
8130 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.

8132 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8133 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8134 (mark_stack, valid_pointer_p, make_pure_string)
8135 (Fgarbage_collect, survives_gc_p, gc_sweep):
8136 Use bool for booleans, instead of int.
8137 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8138 Remove unused local.
8139 * alloc.c (PURE_POINTER_P):
8140 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8141 * editfns.c (Fformat):
8142 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8144 * fns.c (sweep_weak_table):
8145 * lisp.h (suppress_checking, push_message, survives_gc_p)
8146 (make_pure_string, gc_in_progress, abort_on_gc):
8147 * lread.c (readchar, read1):
8148 * print.c (Fprin1_to_string):
8149 * xdisp.c (push_message):
8150 Use bool for booleans affected directly or indirectly by
8153 Make recently-introduced setters macros.
8154 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8155 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8156 (set_fontset_default, set_fontset_fallback): Rename from their
8157 upper-case counterparts, and make them functions rather than macros.
8158 This is more consistent with the other recently-introduced setters.
8159 These don't need to be inline, since they're local.
8161 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8163 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8164 the loop (Bug#12247).
8166 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8168 * lisp.h (vcopy): Use memcpy rather than our own loop.
8169 This fixes a performance regression introduced by the recent
8170 addition of vcopy. This means 'vcopy' will need to be modified
8171 for a copying collector, but that's OK. Also, tighten the
8172 checking in the assertion.
8174 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8176 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8177 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8178 non-base glyph for the width of the base character, according to
8179 what x_draw_composite_glyph_string_foreground expects.
8180 Generate WADJUST value according to composition_gstring_width's
8181 expectations, to produce correct width of the composed character.
8182 Reverse the sign of the DU offset produced by ScriptPlace.
8184 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8186 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8188 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8190 Avoid direct writes to contents member of struct Lisp_Vector.
8191 * lisp.h (vcopy): New function to copy data into vector.
8192 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
8193 * fns.c (Ffillarray): Use ASET.
8194 * keyboard.c (timer_check_2): Use AREF and ASET.
8195 (append_tool_bar_item, Frecent_keys): Use vcopy.

8268 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8270 Rely on <config.h> + <unistd.h> to declare 'environ',
8271 as gnulib does this if the system doesn't.
8272 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:

9141 2012-08-04 Eli Zaretskii <eliz@gnu.org>
9143 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
9144 * w32.c (init_environment): Change the default values of many
9145 environment variables in dflt_envvars[] to NULL, to avoid pushing
9146 them into environment when they were not already defined.
9147 Remove the code that deletes site-lisp subdirectories from the default
9148 value of EMACSLOADPATH, as it is no longer needed.
9149 (check_windows_init_file): Now external, not static.
9150 Use Vload_path as is, without adding anything, as this function is now
9151 called when Vload_path is already set up.
9153 * w32.h (check_windows_init_file): Add prototype.
9155 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
9156 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
9157 compatibility with Posix platforms.
9158 (main): Move the call to check_windows_init_file to here from
9160 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if

9162 installation tree, as appropriate.
9164 * callproc.c (init_callproc_1): Call decode_env_path instead of
9165 doing its equivalent by hand.
9166 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
9167 the code that sets Vexec_path run on MS-Windows.
9169 * lread.c (init_lread): Add comments to #ifdef's.
9171 * msdos.c (dos_set_window_size, IT_update_begin)

9179 Now constants, not macros.
9181 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
9183 Remove unnecessary casts involving pointers.
9184 These casts are no longer needed now that we assume C89 or later,
9185 since they involve casting to or from void *.

9187 (make_pure_float, make_pure_vector):
9188 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

9198 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
9199 Remove unnecessary pointer casts.
9200 * alloc.c (record_xmalloc): New function.
9201 * lisp.h (record_xmalloc): New decl.
9202 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9203 more like a function. This is because the pointer cast is not
9204 needed. All uses changed.
9205 * print.c (print_string, print_error_message): Avoid length recalc.
9207 Improve fix for macroexp crash with debugging (Bug#12118).
9208 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9209 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9210 not supposed to be invoked from the garbage collector.
9211 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9212 (gc_aset): New function, which is like ASET but can be
9213 used in the garbage collector.
9214 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)

9229 headers (most versions of MinGW w32api don't).
9230 (get_security_info, create_symbolic_link)
9231 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
9233 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
9234 in the argument file name.

9237 (sys_rename): Diagnose renaming of a symlink when the user doesn't
9238 have the required privileges.
9239 (get_file_security_desc_by_name): Rename from

9242 with addition of handling of symlinks and support for 'lstat'.
9243 If possible, get file's attributes and security information by
9244 handle, not by name. Produce S_IFLNK bit for symlinks, when
9245 called from 'lstat'.
9246 (stat, lstat): New functions, call 'stat_worker'.
9247 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9248 symlinks when the underlying filesystem supports them.
9250 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9252 Fix macroexp crash on Windows with debugging (Bug#12118).
9253 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9254 checking subscripts; problem introduced with the recent
9255 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9256 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9257 since it's used in non-static inline functions now.
9259 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9260 Don't assume buffer size fits in 'int'. Remove unused local.

9278 * character.c (CHARACTER_INLINE):
9279 * charset.c (CHARSET_INLINE):
9280 * composite.c (COMPOSITE_INLINE):
9281 * dispnew.c (DISPEXTERN_INLINE):
9282 * sysdep.c (SYSTIME_INLINE):
9283 Define to EXTERN_INLINE, so that the corresponding functions
9284 are compiled into code.
9285 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
9286 (INLINE_HEADER_END): New macros.
9287 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9309 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9311 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9312 This how ASET and AREF are supposed to work, and makes
9313 it easier to think about future improvements. See
9314 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9315 * charset.h (set_charset_attr): New function.

9568 * s/aix4-2.h (sigmask): No need to undefine it, since syssignal.h
9569 does that unconditionally. Remove file, which is now empty.
9571 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
9574 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
9576 Export to GDB most of lisp.h's remaining object-like macros.

9589 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
9590 Move to after the definition of struct Lisp_Char_Table,
9591 since the former now needs that type defined.

9692 * w32inevt.c: Include w32inevt.h.
9693 (w32_read_console_input): New inline function, calls either
9694 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
9695 w32_console_unicode_input.
9696 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
9697 (w32_kbd_patch_key, key_event): Use the codepage returned by
9698 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

9727 * alloc.c (listn): Fix the order the arguments are consed onto the
9730 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9731 enumeration constants, as PURE and HEAP are too general, and clash
9732 with other headers and sources, such as gmalloc.c and the
9733 MS-Windows system headers. All users changed.
9735 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9737 Revert last save_excursion_save and save_excursion_restore changes.
9738 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9748 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
9750 Improve GDB symbol export (Bug#12036).
9751 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9752 arms of an 'if', not using conditional expressions; otherwise GDB
9753 complains about the types in the unevaluated arm when the argument
9754 is an integer literal.
9755 (xgetint): Simplify expression.
9756 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9757 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9758 Zaretskii in <http://bugs.gnu.org/12036#13>.
9759 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9760 needed now that we have gdb_make_enums_visible.
9761 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9762 (enum enum_USE_LSB_TAG):
9763 New enum types, packaging up enums that need to be exported to GDB.
9765 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

9781 * xdisp.c (syms_of_xdisp): Likewise.
9782 * xfns.c (syms_of_xfns): Likewise.
9784 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9786 Fast save_excursion_save and save_excursion_restore.
9787 * lisp.h (struct Lisp_Excursion): New data type.
9788 (PVEC_EXCURSION): New pseudovector type.
9789 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9790 to deal with it. Adjust comments.

9801 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9803 Fix export of symbols to GDB (Bug#12036).
9804 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9805 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9806 emacs.c, as this is a more-suitable home. Had this been done earlier
9807 the fix for 12036 would have avoided some of the problems noted in
9808 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9809 would have been more obvious.
9810 * emacs.c: Do not include <verify.h>; no longer needed.
9811 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9812 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9813 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9814 Remove; now done in lisp.h.

9819 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9820 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9821 not be usable in #if. This simplifies things.
9823 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9825 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9827 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

9830 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9831 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9832 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9833 Adjust to changes in lisp.h and emacs.c, by using
9834 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9835 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9836 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9837 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9838 instead of gdb_valbits.
9839 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9840 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9841 instead of gdb_array_mark_flag.
9842 (xboolvector): Get size from $->size, not $->header.size.
9843 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9844 (xreload, hook-run, hookpost-run): Remove.
9845 * emacs.c: Include <verify.h>.
9846 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9847 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9849 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9850 (gdb_USE_LSB_TAG): New enum constants.
9851 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9852 Also define these as enum constants, so they're visible to GDB.
9853 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9854 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9855 as constants, so they're visible to GDB.
9856 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9857 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9858 Now enum constants, not macros, so they're visible to GDB.
9859 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9860 more convenient now. All uses changed.
9861 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9862 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9864 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
9866 Explicitly free restriction data that are not needed anymore.
9867 * editfns.c (save_restriction_restore): Free restriction data.
9869 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9871 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9872 add argument, tune behavior, and adjust all callers.
9874 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9876 Use typedef for EMACS_INT, EMACS_UINT.
9877 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9878 than macros. This simplifies debugging in the usual case, since
9879 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9880 and it allows expressions involving EMACS_INT casts.
9881 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9883 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
9885 * nsterm.m (ns_read_socket): Return early if there is a modal

9891 that FOCUS-FRAME can be omitted.
9893 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9895 Adjust buffer text indirection counters at the end of Fkill_buffer.
9896 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9897 buffer is definitely dead. This should really fix an issue reported
9898 by Christoph Scholtes again. (Bug#12007).
9899 (init_buffer_once): Initialize indirection counters of
9900 buffer_defaults and buffer_local_symbols (for sanity and safety).
9902 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9904 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9905 and continuation glyphs on tooltip frames, leave them at zero.
9906 Avoids continued lines in tooltips. (Bug#11832)
9908 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
9910 Simplify copy_overlay.
9911 * buffer.c (copy_overlay): Simplify. Use build_marker.

9917 or invalid. (Bug#12025)
9919 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
9920 it signals an error when a tooltip frame is being created.
9922 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9924 Cleanup miscellaneous objects allocation and initialization.
9925 * alloc.c (allocate_misc): Change to static. Add argument to
9926 specify the subtype. Adjust comment and users.
9927 (build_overlay): New function.
9928 * buffer.c (copy_overlays, Fmake_overlay): Use it.
9929 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
9930 (allocate_misc): Remove prototype.
9931 (build_overlay): Add prototype.
9933 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9935 Swap buffer text indirection counters in Fbuffer_swap_text.
9936 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9937 This avoids crash reported by Christoph Scholtes at
9938 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9940 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9942 * nsmenu.m (Popdown_data): New struct.
9943 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9945 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9946 (initWithContentRect): Make imgView and contentView non-static
9947 and autorelease them. Also autorelease img and matrix (Bug#12005).
9948 (dealloc): Remove (Bug#12005).
9950 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9952 Adjust consing_since_gc when objects are explicitly freed.

10819 * s/gnu.h (DATA_START): Move definitions to configure.
10821 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10822 We include usg5-4-common.h, which defines them both.
10824 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10825 O_RDONLY already includes it).
10827 Stop ns builds setting the EMACSLOADPATH environment variable.
10828 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10829 Now it does not set EMACSLOADPATH, just returns the load-path string.
10830 * nsterm.h: Update accordingly.
10831 * lread.c [HAVE_NS]: Include nsterm.h.
10832 (init_lread) [HAVE_NS]: Use ns_load_path.
10833 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10835 2012-07-09 Glenn Morris <rgm@gnu.org>
10837 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10838 since the included bsd-common.h does so.
10840 Stop ns builds setting the EMACSPATH environment variable.
10841 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10842 (ns_init_paths): Do not set EMACSPATH.
10843 * nsterm.h (ns_exec_path): Add it.
10844 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10847 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10849 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10851 * process.c (wait_reading_process_output): 'waitchannels' was unset
10852 when read_kbd || !NILP (wait_for_cell); fix this.
10854 Add GCC-style 'const' attribute to functions that can use it.
10855 * character.h (char_resolve_modifier_mask):
10856 * keyboard.h (make_ctrl_char):
10857 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10858 (init_character_once, next_almost_prime, init_fns, init_image)
10859 (flush_pending_output, init_sound):
10860 * mem-limits.h (start_of_data):
10861 * menu.h (finish_menu_items):

10863 * emacs.c (DEFINE_DUMMY_FUNCTION):
10864 Declare the dummy function with ATTRIBUTE_CONST.
10865 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
10866 Add decls with ATTRIBUTE_CONST.
10868 Minor improvements to make_formatted_string.
10869 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10870 where int is good enough, as vsprintf returns an int.
10871 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10873 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10875 Use make_formatted_string to avoid double length calculation.
10876 * lisp.h (make_formatted_string): New prototype.
10877 * alloc.c (make_formatted_string): New function.
10878 * buffer.c (Fgenerate_new_buffer_name): Use it.

10891 2012-07-09 Glenn Morris <rgm@gnu.org>
10893 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10894 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10895 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10898 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10900 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10902 Move marker debugging code under MARKER_DEBUG.
10903 * marker.c (MARKER_DEBUG): Move marker debugging code under
10904 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10905 for bootstrap with --enable-checking (~3x slowdown reported
10906 by Juanma Barranquero <lekktu@gmail.com>).
10907 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10909 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10911 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10912 See <http://bugs.gnu.org/11825#29>.
10914 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10916 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10917 has no font, use the frame's font. (Bug#11813)
10918 (display_line): Add commentary about displaying truncation glyphs
10920 (produce_special_glyphs): Move here from term.c.
10922 * term.c (produce_special_glyphs): Move to xdisp.c.
10924 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10927 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10929 * xdisp.c (display_line): Avoid warning about implicit declaration
10932 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10934 * lisp.h: Remove empty conditional.
10936 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10938 * lread.c (load_path_check): Now static.
10940 Fix some minor --with-ns problems found by static checking.
10941 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10942 (x_set_font) [!HAVE_X_WINDOWS]:
10943 * image.c (xpm_load_image) [HAVE_NS]:
10944 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10945 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10946 Remove unused local.
10947 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10948 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10949 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10950 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10951 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10952 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10953 Fix pointer signedness problem.
10954 * xfaces.c (FRAME_X_FONT_TABLE):
10955 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10957 2012-07-07 Glenn Morris <rgm@gnu.org>
10959 * lread.c (load_path_check): New function, split from init_lread.
10960 (init_lread): Reorganize. Motivation:
10961 If EMACSLOADPATH is set, check/warn about that rather than the
10962 defaults, which we are not going to use. Hence we can remove
10963 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10964 Don't warn if site-lisp directories are missing.
10965 If not installed, start from a blank load-path, since
10966 PATH_LOADSEARCH refers to the eventual installation directories.
10968 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10970 Support truncation and continuation glyphs on GUI frames, when
10971 fringes are disabled. (Bug#11832)
10972 * xdisp.c (init_iterator): Get dimensions of truncation and
10973 continuation glyphs even if on GUI frames.
10974 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10975 or both, are absent.
10976 (start_display, move_it_in_display_line_to): Handle the case of a
10977 GUI frame without a fringe to display continuation or truncation
10979 (insert_left_trunc_glyphs): Support GUI frames: make sure
10980 truncation glyphs overwrite enough glyphs from the current line to
10981 have sufficient space in pixels.
10982 (display_line): Support truncation and continuation glyphs on GUI
10983 frames. If some spare pixels are left on the line after inserting
10984 the truncation glyphs, fill that space with a stretch glyph of a
10985 suitably computed width.
10987 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10988 produce_glyphs, to support GUI sessions.
10990 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10992 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10994 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10996 Do not require float-time's arg to fit in time_t (Bug#11825).
10997 This works better on hosts where time_t is unsigned, and where
10998 float-time is applied to the (negative) difference between two times.
10999 * editfns.c (decode_time_components): Last arg is now double *,
11000 not int *, and means to store all the result as a double, without
11001 worrying about whether the seconds part fits in time_t.
11002 All callers changed.
11003 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
11004 All callers changed.
11005 (Ffloat_time): Do not fail merely because the specified time falls
11006 outside of time_t range.
11008 2012-07-07 Glenn Morris <rgm@gnu.org>
11010 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
11011 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
11012 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
11014 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
11016 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
11017 Update dependencies.

11025 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
11026 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
11027 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
11028 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
11030 * xfont.c (compare_font_names): Redo to omit the need for casts.
11032 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
11034 * xfns.c (Fx_change_window_property): Doc fix.
11035 * w32fns.c (Fx_change_window_property): Doc fix.
11037 * w32fns.c (Fx_window_property): Accept the same arguments as the
11038 X Windows version. Doc fix.
11039 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
11041 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
11042 Eli Zaretskii <eliz@gnu.org>
11044 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
11045 Windows-specific code from nt/config.nt moved here.
11046 Obsolete settings removed.
11048 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11050 * process.c: Avoid unnecessary calls to gettime.
11051 (wait_reading_process_output): Don't get the time of day
11052 when gobbling data immediately and not waiting, as there's no need
11053 for it in that case. This removes a FIXME.
11055 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
11057 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
11058 is defined (Bug#11768).
11060 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11062 Fix marker debugging code.

11064 if buffer is not multibyte.
11065 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11066 Call byte_char_debug_check with correct arguments.
11068 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11070 Compile marker debugging code only if ENABLE_CHECKING is defined.
11071 * marker.c (byte_char_debug_check, count_markers):
11072 Use only if ENABLE_CHECKING is defined.
11073 (byte_debug_flag): Remove.
11074 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
11075 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
11077 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11079 Avoid code repetition in marker-related functions.

11084 Consistently rename charno to charpos.
11085 (marker_position): Add eassert.
11086 (marker_byte_position): Convert to eassert.
11088 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

11102 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11103 (save_restriction_save): Use build_marker.
11104 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11105 * window.c (save_window_save): Likewise.
11107 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11109 Do not use Fdelete_overlay in delete_all_overlays
11110 to avoid redundant calls to unchain_overlay.

11112 (delete_all_overlays, Fdelete_overlay): Use it.
11113 * minibuf.c (get_minibuffer): Fix comment.
11115 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11117 Port to OpenBSD 5.1 amd64.
11118 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11119 This is needed for OpenBSD, and should be harmless on all BSD systems.
11120 Also, include <sys/sysctl.h>, as it should be available on all
11121 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11122 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11123 use p_pid member, not kp_proc.pid.
11125 2012-07-06 Glenn Morris <rgm@gnu.org>
11127 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11129 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11131 More xmalloc and related cleanup.

11140 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11142 Omit needless casts involving void * pointers and allocation.
11143 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11144 as the former is more robust if P's type is changed.
11145 Prefer xzalloc to xmalloc + memset 0.
11146 Simplify malloc-or-realloc to realloc.
11147 Don't worry about xmalloc returning a null pointer.
11148 Prefer xstrdup to xmalloc + strcpy.
11149 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11151 * keyboard.c (apply_modifiers_uncached): Prefer local array to

11156 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11157 hscroll is larger than the line width. Fixes long and futile
11158 looping inside extend_face_to_end_of_line (on a TTY) producing
11159 glyphs that are not needed and thrown away.
11161 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

11177 followed by gtk_box_set_homogeneous (Bug#11768).
11178 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11179 (update_theme_scrollbar_width, xg_create_scroll_bar):
11180 Use gtk_scrollbar_new (Bug#11768).

11182 (is_box_type): New function (Bug#11768).
11183 (xg_tool_item_stale_p): Call is_box_type.
11184 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11185 with default display (Bug#11768).
11187 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11189 * xdisp.c (window_hscroll_limited): New function.
11190 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11191 coordinates when window's hscroll is set to insanely large
11192 values. (Bug#11857)
11194 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11255 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11257 * fileio.c (time_error_value): Check the right error number.
11258 Problem reported by Troels Nielsen in
11259 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11261 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11263 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11264 This should be fixed in a better way; see Eli Zaretskii in
11265 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11266 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11268 * fileio.c (time_error_value): Rename from special_mtime.
11269 The old name's problems were noted by Eli Zaretskii in
11270 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11272 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11273 This variable's comment says Emacs needs at least one GDB-visible
11274 symbol of type enum pvec_type, to work around GDB problems.
11275 The symbol's value doesn't matter.
11277 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11278 that causes compilation to fail on pre-C99 compilers.
11280 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11282 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
11283 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
11285 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11287 * buffer.c (init_buffer_once): Fix initialization of
11288 headers for buffer_defaults and buffer_local_symbols.
11289 Reported by Juanma Barranquero <lekktu@gmail.com>.
11291 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11293 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11294 * lisp.h (enum pvec_type): Use fewer bits.
11295 (PSEUDOVECTOR_SIZE_BITS): New constant.
11296 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11297 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11298 change in pvec_type.
11299 (PSEUDOVECTOR_TYPEP): New macro.
11300 (TYPED_PSEUDOVECTORP): Use it.
11301 * fns.c (internal_equal): Adapt code to extract pvectype.
11302 * emacs.c (gdb_pvec_type): Update type.
11303 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11304 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11305 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11306 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11307 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11308 abusing vector->header.next.nbytes.
11309 (live_vector_p): Use PVEC_TYPE.
11310 (mark_object): Adapt code to extract pvectype. Use switch.
11312 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11314 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11315 Tighten new eassert a bit.
11317 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11319 Fix compilation with --enable-gcc-warnings and -O1
11320 optimization level.
11321 * doprnt.c (doprnt): Change type of tem to int, initialize
11322 to avoid compiler warning. Add eassert.
11323 * search.c (simple_search): Initialize match_byte to avoid
11324 compiler warning. Add eassert.
11326 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11328 Avoid weird behavior with large horizontal scrolls.
11329 Without this change, for example, large hscroll values would
11330 mess up Emacs's display on Fedora 15 x86, presumably due to
11331 overflows in int calculations in the display code.
11332 Also, if buffers had long lines, Emacs would freeze.
11333 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11334 (set_window_hscroll): New function, containing the old guts of
11335 Fset_window_hscroll. Return the clipped value.
11336 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11337 This avoids the need to check against PTRDIFF_MAX.
11339 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11341 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11343 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11345 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11347 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11348 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11349 since GCC 4.4.6 issues a bogus warning for them.
11351 Fix bugs in file timestamp newness comparisons.
11352 * fileio.c (Ffile_newer_than_file_p):
11353 * lread.c (Fload): Use full timestamp resolution of files,
11354 not just the 1-second resolution, so that files that are only
11355 slightly newer still count as newer.
11356 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11357 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11359 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11361 * fileio.c: Improve handling of file time marker. (Bug#11852)
11362 (special_mtime): New function.
11363 (Finsert_file_contents, Fverify_visited_file_modtime):
11364 Use it to set special mtime values consistently.
11366 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11368 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11369 marker for non-existing file. (Bug#11852)
11371 2012-07-03 Glenn Morris <rgm@gnu.org>
11373 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11374 and did not make it into globals.h).
11376 2012-07-03 Tom Tromey <tromey@redhat.com>
11378 * window.c (Fset_window_margins, Fset_window_fringes)
11379 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11380 * textprop.c (Fprevious_property_change): No longer static.
11381 * syntax.c (Fsyntax_table_p): No longer static.
11382 * process.c (Fget_process, Fprocess_datagram_address): No longer

11405 * font.h: Remove EXFUNs.
11406 * dosfns.c (system_process_attributes): Remove EXFUN.
11407 * keymap.h: Remove EXFUNs.
11408 * lisp.h: Remove EXFUNs.
11409 * w32term.h: Remove EXFUNs.
11410 * window.h: Remove EXFUNs.
11411 * xsettings.h: Remove EXFUN.
11412 * xterm.h: Remove EXFUN.
11414 2012-07-03 Glenn Morris <rgm@gnu.org>
11416 * lisp.h (Frandom): Make it visible to C.
11417 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11418 buffer for invisible buffers. (Bug#1229)
11420 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11422 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11423 values which aren't power of 2.
11424 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11425 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11428 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11430 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11432 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11434 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11436 * alloc.c (allocate_vector_block): Remove redundant
11437 calls to mallopt if DOUG_LEA_MALLOC is defined.
11438 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11439 avoid calls to mallopt if zero_vector is returned.
11441 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11443 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11444 is enabled, avoid dereferencing NULL current_sblock if
11447 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11449 Cleanup basic buffer management.
11450 * buffer.h (struct buffer): Change layout to use generic vector
11451 marking code. Fix some comments. Change type of 'clip_changed'
11452 to bitfield. Remove unused #ifndef old.
11453 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11454 (GET_OVERLAYS_AT): Fix indentation.
11455 (for_each_per_buffer_object_at): New macro.
11456 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

11460 struct buffer. Fix comment.
11461 (mark_overlay): New function.

11464 (mark_object): Use it. Adjust marking of misc objects
11465 and related comments.
11467 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11469 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11470 wrapper that is not needed because the wrapped code is a no-op (zero
11471 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11472 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11474 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11476 * alloc.c (mark_buffer): Simplify. Remove prototype.
11477 (mark_object): Add comment. Reorganize marking of vector-like
11478 objects. Use CHECK_LIVE for all vector-like objects except buffers
11479 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11480 Avoid redundant calls to mark_vectorlike for bool vectors.
11482 2012-06-30 Glenn Morris <rgm@gnu.org>
11484 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11486 * epaths.in (PATH_SITELOADSEARCH): New.
11487 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11488 This is rather than relying on --enable-locallisppath elements
11489 having "site-lisp" in their names. (Bug#10208#25, 11658)
11491 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11493 * w32proc.c (sys_select): Accept and ignore one more argument.
11495 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11497 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11498 (pselect) [!MS_DOS]: Redirect to sys_select.
11500 * sysdep.c: Don't include dos.h and dosfns.h.
11502 * process.c (sys_select):
11503 * msdos.c (sys_select): Accept one more argument and ignore it.
11505 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11506 adapt data types and code to that.
11509 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11510 which clashes with the gnulib function of the same name.
11512 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11514 * font.c (font_style_to_value, font_style_symbolic)
11515 (font_prop_validate_style): Add type checks for values in
11518 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11520 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11523 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11525 * xdisp.c (try_window_id): Undo last change.
11527 * w32.c (getwd): Adjust commentary about startup_dir.
11528 (init_environment): Always call sys_access, even in non-MSVC
11529 builds. Don't chdir to the directory of the Emacs executable.
11530 This undoes code from 1997 which was justified by the need to
11531 "avoid conflicts when removing and renaming directories". But its
11532 downside was that every relative file name was being interpreted
11533 relative to the directory of the Emacs executable, which can never
11534 be TRT. In particular, it broke sys_access when called with
11535 relative file names.
11536 (sys_access): Map GetLastError to errno.
11538 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11544 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11547 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11549 * gnutls.c (emacs_gnutls_handshake):
11550 Add QUIT to make the loop interruptible.
11552 2012-06-29 Glenn Morris <rgm@gnu.org>
11554 * charset.c (init_charset): Make lack of etc/charsets fatal.
11556 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11558 * editfns.c (region_limit): Fix type mismatch.
11560 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11562 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11563 undefined. Convert from xassert to eassert.
11564 * nsmenu.m: Convert from xassert to eassert.
11565 * nsterm.m: Likewise.
11567 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11569 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11571 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11573 Avoid integer overflow on scroll-left and scroll-right.
11574 * window.c (HSCROLL_MAX): New macro.
11575 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11576 overflow when requested scroll falls outside ptrdiff_t range.
11578 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11580 * window.h (struct window): Change type of 'hscroll',
11581 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11582 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11583 Adjust users accordingly.
11584 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11585 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11586 from EMACS_INT to ptrdiff_t.
11587 (make_window): Omit redundant initialization.
11589 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
11591 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
11593 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>

11606 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11607 adjust comments accordingly.

11609 undefined, adjust comments accordingly.

11656 * alloc.c (allocate_string_data): Remove dead code.

11730 Use sprintf return value instead of invoking strlen on result.
11731 In the old days this wasn't portable, since some sprintf
11732 implementations returned char *. But they died out years ago and
11733 Emacs already assumes sprintf returns int.
11734 Similarly for float_to_string.
11735 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
11736 * ccl.c (ccl_driver):
11737 * character.c (string_escape_byte8):

11740 * print.c (print_object):
11741 * xdisp.c (message_dolog):
11742 * xfns.c (syms_of_xfns):
11743 Use sprintf or float_to_string result to avoid need to call strlen.
11744 * data.c (Fnumber_to_string):
11745 Use make_unibyte_string, since the string must be ASCII.
11746 * lisp.h, print.c (float_to_string): Now returns int length.
11747 * term.c (produce_glyphless_glyph):
11748 Use sprintf result rather than recomputing it.
11750 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11751 * Makefile.in (ALL_CFLAGS):
11752 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

11755 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11757 * dispextern.h (xstrcasecmp): Define to library function
11758 strcasecmp if available.

11779 * xfns.c (x_window): Remove redundant cast.
11781 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11783 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11784 `const char *' to `char *' to avoid compiler warning.
11786 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11788 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11789 instead of truncating it to 63 (admittedly a generous limit).
11791 * process.c: Fix spelling and caps in comments.
11793 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11795 * emacs.c (setpgrp): Remove definition, unused.

11809 * s/ms-w32.h (struct timespec): Definition moved from
11810 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
11812 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

11842 Remove unnecessary forward decls.
11844 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11846 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

11848 * dispnew.c (Fsleep_for, sit_for):
11849 * keyboard.c (kbd_buffer_get_event):
11850 * process.c (Faccept_process_output):
11851 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11852 This improves on the previous patch, which introduced a bug
11853 when time_t is unsigned and as wide as intmax_t.
11854 See <http://bugs.gnu.org/9000#51>.
11856 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11874 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
11876 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
11877 not make_lisp_timeval, when the argument is of type EMACS_TIME.
11879 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11885 language ID in the event parameters.
11887 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11888 event.code, not the obscure "character set ID".
11890 2012-06-23 Chong Yidong <cyd@gnu.org>
11892 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

11919 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11921 Support higher-resolution time stamps (Bug#9000).
11922 The time stamps are only nanosecond-resolution at the C level,
11923 since that's the best that any real-world system supports now.
11924 But they are picosecond-resolution at the Lisp level, as that's
11925 easy, and leaves room for future OS improvements.
11927 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11930 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11931 Don't get current time unless it's needed.
11933 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11934 now provides it if it's absent.
11935 (start_atimer): Port to higher-res time stamps.
11936 Check for time stamp overflow. Don't get current time more
11937 often than is needed.
11939 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11940 Include systime.h, not time.h.
11941 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11943 * dired.c: Include stat-time.h.
11944 (Ffile-attributes): File times now have higher resolution.
11946 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11947 (struct image): Timestamp now has higher resolution.
11949 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11950 has at least microseconds now. All uses removed.
11951 (update_frame, update_single_window, update_window, update_frame_1)
11952 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11953 (duration_to_sec_usec): Remove; no longer needed.
11955 * editfns.c (time_overflow): Now extern.
11956 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
11957 (float-time, Fformat_time_string, Fcurrent_time_string)
11958 (Fcurrent_time_zone): Accept and generate higher-resolution
11960 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
11961 (decode_time_components, lisp_seconds_argument): New functions.
11962 (make_time): Now static.
11963 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11964 Report an error if the time is invalid, rather than having the caller
11967 * fileio.c: Include <stat-time.h>
11968 (Fcopy_file): Copy higher-resolution time stamps.
11969 Prefer to set the time stamp via a file descriptor if that works.
11970 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11971 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11972 (Fvisited_file_modtime, Fset_visited_file_modtime):
11973 Support higher-resolution time stamps.
11975 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11977 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11979 * image.c (prepare_image_for_display, clear_image_cache)
11980 (lookup_image): Port to higer-resolution time stamps.
11982 * keyboard.c (start_polling, bind_polling_period):
11983 Check for time stamp overflow.
11984 (read_char, kbd_buffer_get_event, timer_start_idle)
11985 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11986 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11987 Port to higher-resolution time stamps. Do not assume time_t is signed.
11988 (decode_timer): New function. Timers are now vectors of length 9,
11989 not 8, to accommodate the picosecond component.
11990 (timer_check_2): Use it.
11992 * nsterm.m (select_timeout, timeval_subtract): Remove.
11993 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11994 as they're a bit more accurate and handle overflow better.
11995 (ns_select): Change prototype to be compatible with pselect.
11996 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11997 * nsterm.h (ns_select): Adjust prototype.
11999 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
12000 us-resolution time stamps.
12001 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
12003 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
12005 * lisp.h (time_overflow): New decl.
12006 (wait_reading_process_output): First arg is now intmax_t, not int,
12007 to accommodate larger waits.
12009 * process.h (struct Lisp_Process.read_output_delay):
12010 Now counts nanoseconds, not microseconds.
12011 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
12013 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
12014 (wait_reading_process_output):
12015 Port to ns-resolution time stamps.
12016 (Faccept_process_output, wait_reading_process_output):
12017 Check for time stamp overflow. Do not assume time_t is signed.
12018 (select_wrapper): Remove; we now use pselect.
12019 (Fprocess_attributes): Now generates ns-resolution time stamps.
12021 * sysdep.c: Include utimens.h. Don't include utime.h
12022 or worry about struct utimbuf; gnulib does that for us now.
12023 (gettimeofday): Remove; gnulib provides a substitute.
12024 (make_timeval): New function.
12025 (set_file_times): Now sets ns-resolution time stamps.
12026 New arg FD; all uses changed.
12027 (time_from_jiffies, ltime_from_jiffies, get_up_time)
12028 (system_process_attributes):
12029 Now returns ns-resolution time stamp. All uses changed.
12030 Check for time stamp overflow.
12032 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
12033 provides a substitute now.
12035 * systime.h: Include timespec.h rather than sys/time.h and time.h,
12036 since it guarantees struct timespec.
12037 (EMACS_TIME): Now struct timespec, so that we can support
12038 ns-resolution time stamps.
12039 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
12040 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
12041 (EMACS_USECS): Remove.
12042 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
12043 so multiply the arg by 1000 before storing it.
12044 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
12046 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
12047 Port to ns-resolution time stamps.
12048 (EMACS_TIME_NEG_P): Remove; replaced by....
12049 (EMACS_TIME_SIGN): New macro.

12051 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
12052 (set_file_times, make_time, lisp_time_argument): Adjust signature.
12053 (make_timeval, make_lisp_time, decode_time_components): New decls.
12054 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
12055 that it mishandled time_t overflow. You can't compare by subtracting!
12056 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
12057 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
12059 * term.c: Include <sys/time.h>.
12060 (timeval_to_Time): New function, for proper overflow wraparound.
12061 (term_mouse_position, term_mouse_click): Use it.
12063 * undo.c (record_first_change): Support higher-resolution time stamps
12064 in the undo buffer.
12065 (Fprimitive_undo): Use them when restoring time stamps.
12067 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
12068 (w32_get_internal_run_time):
12069 Port to higher-resolution Emacs time stamps.
12070 (ltime): Now accepts single 64-bit integer, as that's more convenient
12073 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
12075 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
12076 for compatibility with pselect. Support ns-resolution time stamps.
12078 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12080 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12081 Check for time stamp overflow, and support ns-resolution time stamps.
12083 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12084 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12085 (timeval_subtract): Remove; no longer needed.
12086 (XTflash, XTring_bell, x_wait_for_event):
12087 Port to ns-resolution time stamps. Don't assume time_t is signed.
12089 2012-06-22 Chong Yidong <cyd@gnu.org>

12093 2012-06-22 Eli Zaretskii <eliz@gnu.org>
12095 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12096 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12097 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12098 staticidx goes up to 1597 out of 1600 = 0x640.)
12100 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12102 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
12103 Otherwise, the umask might be mistakenly 0 while handling input signals.
12105 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>

12114 access to `contents' member of Lisp_Vector objects with AREF and ASET
12117 2012-06-19 Chong Yidong <cyd@gnu.org>
12119 * frame.c (delete_frame): When selecting a frame on a different
12120 text terminal, do not alter the terminal's top-frame.
12122 * xdisp.c (format_mode_line_unwind_data): Record the target
12123 frame's selected window and its terminal's top-frame.
12124 (unwind_format_mode_line): Restore them.
12125 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
12127 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
12128 since tty frames can be explicitly named.
12129 (prepare_menu_bars): Likewise.
12131 * term.c (Ftty_top_frame): New function.
12133 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12135 Port byte-code-meter to modern targets.
12136 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
12137 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
12138 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
12139 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
12140 (METER_1, METER_2): Simplify.
12142 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
12144 * data.c (Fdefalias): Return `symbol' (bug#11686).
12146 2012-06-18 Martin Rudalics <rudalics@gmx.at>
12148 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
12149 gets killed during executing of this function (Bug#11665).
12150 Try to always return Qt when the buffer has been actually killed.
12151 (Vkill_buffer_query_functions): In doc-string say that functions
12152 run by this hook should not change the current buffer.
12154 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12156 Fix recently-introduced process.c problems found by static checking.
12157 * process.c (write_queue_push, write_queue_pop, send_process):
12158 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
12159 (write_queue_pop): Fix pointer signedness problem.
12160 (send_process): Remove unused local.
12162 2012-06-17 Chong Yidong <cyd@gnu.org>

12373 Use an inline function on all platforms when using the union type,

12519 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12520 would mishandle a string argument "Xc" if X was a multibyte

12575 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12576 Convert pctcpu and pctmem to Lisp float properly.

12603 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12604 Use 'float' consistently, rather than 'float' in most places
12605 and 'double' in a couple of places.
12607 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12609 * xdisp.c (handle_stop): Detect whether we have overlay strings
12610 loaded by testing it->current.overlay_string_index to be

12620 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12622 * search.c (search_buffer): Remove calls to
12623 r_alloc_inhibit_buffer_relocation, as it is now called by
12624 maybe_unify_char, which was the cause of relocation of buffer text
12627 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12629 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12630 for the duration of call to load_charset, to avoid problems with
12631 callers of maybe_unify_char that access buffer text through C
12634 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12635 decrement the inhibition flag, instead of just setting or
12638 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12640 Remove obsolete '#define static' cruft.
12641 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12642 This #undef was "temporary" in 2000; it is no longer needed
12643 now that '#define static' has gone away.
12644 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12645 (gray_bitmap_bits): Remove; no longer needed.
12646 All uses replaced with definiens.
12647 * xterm.c: Include "bitmaps/gray.xbm".
12649 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12651 Clean up __executable_start, monstartup when --enable-profiling.
12652 The following changes affect the code only when profiling.
12653 * dispnew.c (__executable_start): Rename from safe_bcopy.
12654 Define only on platforms that need it.
12655 * emacs.c: Include <sys/gmon.h> when profiling.
12656 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12657 (__executable_start): Remove decl, since lisp.h does it now.
12658 (safe_bcopy): Remove decl; no longer has that name.
12659 (main): Coalesce #if into single bit of code, for simplicity.
12660 Cast pointers to uintptr_t, since standard libraries want integers
12662 * lisp.h (__executable_start): New decl.
12664 2012-05-31 Glenn Morris <rgm@gnu.org>
12666 * image.c (Fimagemagick_types): Doc fix.
12668 2012-05-30 Jim Meyering <meyering@redhat.com>
12670 * callproc.c (Fcall_process_region): Include directory component
12671 in mkstemp error message (Bug#11586).
12673 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12675 * alloc.c, lisp.h (make_pure_vector): Now static.
12677 2012-05-30 Stefan Monnier <monnier@iro.umontreal.ca>
12679 * eval.c (Fdefun, Fdefmacro, Vmacro_declaration_function):
12680 Move to byte-run.el.
12681 (Fautoload): Do the hash-doc more carefully.
12682 * data.c (Fdefalias): Purify definition, except for keymaps.
12683 (Qdefun): Move from eval.c.
12684 * lisp.h (Qdefun): Remove.
12685 * lread.c (read1): Tiny simplification.
12687 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
12689 Do not create empty overlays with the evaporate property (Bug#9642).
12690 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12691 Bug#9642, but explicitly check that the buffer the overlay would
12692 be moved to is live and rearrange lines to make sure that errors
12693 will not put the overlay in an inconsistent state.
12694 (Fdelete_overlay): Cosmetics.
12696 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12698 * w32term.c (my_bring_window_to_top): New function.
12699 (x_raise_frame): Use handle returned by DeferWindowPos, which
12700 could be different from the original one.
12701 Call my_bring_window_to_top instead of my_set_foreground_window.
12704 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
12705 by calling BringWindowToTop.
12707 * w32term.h (WM_EMACS_BRINGTOTOP): New message.

12710 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12712 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12713 This avoids undefined behavior that might cause the eassert
12714 to not catch an out-of-range value.
12716 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12718 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
12719 Update dependencies.
12721 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12723 * bidi.c (bidi_mirror_char): Fix last change.
12725 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
12727 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
12728 when referring to sectname field in printf format.
12730 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12732 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12733 Only r_alloc_inhibit_buffer_relocation needed to be added;
12734 the others were already declared.
12736 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12737 before checking whether it's out of range. Put the check inside
12739 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12741 2012-05-27 Ken Brown <kbrown@cornell.edu>
12743 * callproc.c (Fcall_process): Restore a line that was accidentally
12744 commented out in the 2011-02-13 change (bug#11547).
12746 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12748 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12749 defined on ralloc.c.
12751 * buffer.c [REL_ALLOC]: Remove prototypes of
12752 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12753 they are now on lisp.h.
12755 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12757 * search.c (search_buffer): Use it to inhibit relocation of buffer
12758 text while re_search_2 is doing its job, because re_search_2 is
12759 passed C pointers to buffer text. (Bug#11519)
12761 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12762 Update value to 24.
12764 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12765 state after an additional call to move_it_in_display_line_to, keep
12766 the values of it->max_ascent and it->max_descent found for the
12768 (pos_visible_p): Revert the comparison against bottom_y to what it
12769 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12772 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12774 Fix coding-related core dumps with gcc -ftrapv.
12775 The code was computing A - B, where A and B are pointers, and B is
12776 random garbage. This can lead to core dumps on platforms that
12777 have special pointer registers, and it also leads to core dumps on
12778 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12779 A - B only when B is initialized properly.
12780 * coding.c (coding_set_source, coding_set_destination): Return void.
12781 (coding_change_source, coding_change_destinations): New functions,
12782 with the old behaviors of coding_set_source and coding_set_destination.
12783 All callers that need an offset changed to use these new functions.
12785 2012-05-26 Glenn Morris <rgm@gnu.org>
12787 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12789 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12791 Extend mouse support on W32 text-mode console.
12792 * xdisp.c (draw_row_with_mouse_face):
12793 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12795 * w32console.c: Include window.h.
12796 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12798 (initialize_w32_display): Initialize mouse-highlight data.
12800 * w32inevt.c: Include termchar.h and window.h.
12801 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12802 moves, call note_mouse_highlight. If help_echo changed, call
12803 gen_help_event to produce help-echo message in the echo area.
12804 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12807 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12809 * lread.c (read1): Simplify slightly to avoid an overflow warning
12810 with GCC 4.7.0 on x86-64.
12812 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12814 * bidi.c (bidi_mirror_char): Revert last change: an int is
12815 definitely wide enough here.
12817 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12819 Fix integer width and related bugs (Bug#9874).
12820 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
12821 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
12822 (string_bytes, check_sblock, allocate_string_data):
12823 (compact_small_strings, Fmake_bool_vector, make_string)
12824 (make_unibyte_string, make_multibyte_string)
12825 (make_string_from_bytes, make_specified_string)
12826 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12827 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12829 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12830 (allocate_pseudovector):
12831 Use int, not EMACS_INT, where int is wide enough.
12832 (inhibit_garbage_collection, Fgarbage_collect):
12833 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12834 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12835 int might not be wide enough.
12836 (bidi_cache_search, bidi_cache_find, bidi_init_it)
12837 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
12838 (bidi_at_paragraph_end, bidi_find_paragraph_start)
12839 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12840 (bidi_level_of_next_char, bidi_move_to_visually_next):
12841 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12842 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12843 (Fkill_buffer, Fset_buffer_major_mode)
12844 (advance_to_char_boundary, Fbuffer_swap_text)
12845 (Fset_buffer_multibyte, overlays_at, overlays_in)
12846 (overlay_touches_p, struct sortvec, record_overlay_string)
12847 (overlay_strings, recenter_overlay_lists)
12848 (adjust_overlays_for_insert, adjust_overlays_for_delete)
12849 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
12850 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
12851 (Foverlay_recenter, last_overlay_modification_hooks_used)
12852 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12853 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12854 (validate_region): Omit unnecessary test for b <= e,
12855 since that's guaranteed by the previous test.
12856 (adjust_overlays_for_delete): Avoid pos + length overflow.
12857 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12858 (report_overlay_modification):
12859 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12860 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12861 Omit pointer cast, which isn't needed anyway, and doesn't work
12862 after the EMACS_INT -> ptrdiff_t change.
12863 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12864 * buffer.h: Adjust decls to match defn changes elsewhere.
12865 (struct buffer_text, struct buffer):
12866 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12867 Use EMACS_INT, not int, where int might not be wide enough.
12868 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12869 not int, to avoid needless 32-bit limit on 64-bit hosts.
12870 (exec_byte_code): Use tighter memory-full test, one that checks
12871 for alloca overflow. Don't compute the address of the object just
12872 before an array, as that's not portable. Use EMACS_INT, not
12873 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12874 * callint.c (Fcall_interactively):
12875 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12876 * callproc.c (call_process_kill, Fcall_process):
12877 Don't assume pid_t fits into an Emacs fixnum.
12878 (call_process_cleanup, Fcall_process, child_setup):
12879 Don't assume pid_t fits into int.
12880 (call_process_cleanup, Fcall_process, delete_temp_file)
12881 (Fcall_process_region):
12882 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12883 (Fcall_process): Simplify handling of volatile integers.
12884 Use int, not EMACS_INT, where int will do.
12885 * casefiddle.c (casify_object, casify_region, operate_on_word)
12886 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12887 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12888 (casify_object): Avoid integer overflow when overallocating buffer.
12889 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12890 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12891 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12892 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12893 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12894 integers are now checked earlier. All uses replaced with XINT.
12896 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12897 For CCL_MapSingle, check that content and value are in int range.
12898 (ccl_driver, Fregister_code_conversion_map):
12899 Check that Vcode_version_map_vector is a vector.
12900 (resolve_symbol_ccl_program): Check that vector header is in range.
12901 Always copy the vector, so that we can check its contents reliably
12902 now rather than having to recheck each instruction as it's being
12903 executed. Check that vector words fit in 'int'.
12904 (ccl_get_compiled_code, Fregister_ccl_program)
12905 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12906 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12907 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12908 contents are in range.
12909 (Fccl_execute_on_string): Check that status is in range.
12910 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12911 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12912 Accept and return EMACS_INT, not int, because callers can pass values
12913 out of 'int' range.
12914 (c_string_width, strwidth, lisp_string_width, chars_in_text)
12915 (multibyte_chars_in_text, parse_str_as_multibyte)

12917 (str_as_unibyte, str_to_unibyte, string_count_byte8)
12918 (string_escape_byte8, Fget_byte):
12919 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12920 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12921 avoid mishandling large integers.
12922 * character.h: Adjust decls to match defn changes elsewhere.
12923 * charset.c (load_charset_map_from_file, find_charsets_in_text)
12924 (Ffind_charset_region):
12925 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12926 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
12927 (load_charset_map_from_vector, Fdefine_charset_internal):
12928 Don't assume fixnum fits in int.
12929 (load_charset_map_from_vector, Fmap_charset_chars):
12930 Remove now-unnecessary CHECK_NATNUMs.
12931 (Fdefine_charset_internal): Check ranges here, more carefully.
12932 Don't rely on undefined behavior with signed left shift overflow.
12933 Don't assume unsigned int fits into fixnum, or that fixnum fits
12934 into unsigned int. Don't require max_code to be a valid fixnum;
12935 that's not true for gb10830 4-byte on a 32-bit host. Allow
12936 invalid_code to be a cons, for the same reason. Require code_offset
12937 to be a character. Avoid int overflow if max_char is close
12939 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12940 this is intended anyway and avoids some undefined behavior.
12941 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12942 INDEX_TO_CODE_POINT, as that's what it expects.
12943 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12944 * charset.h (DECODE_CHAR): Return int, not unsigned;
12945 this is what was intended anyway, and it avoids undefined behavior.
12946 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12947 integer-overflow issues.
12948 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12949 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12950 where the argument is EMACS_INT, and this behavior is not intended.
12951 * chartab.c (Fmake_char_table, Fset_char_table_range)
12952 (uniprop_get_decoder, uniprop_get_encoder):
12953 Don't assume fixnum fits in int.
12954 * cmds.c (move_point): New function, that does the gist of
12955 Fforward_char and Fbackward_char, but does so while checking
12956 for integer overflow more accurately.
12957 (Fforward_char, Fbackward_char): Use it.
12958 (Fforward_line, Fend_of_line, internal_self_insert)
12959 (internal_self_insert):
12960 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12961 Fix a FIXME, by checking for integer overflow when calculating
12962 target_clm and actual_clm.

12994 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12995 (consume_chars): Rewrite to not calculate an address outside buffer.
12996 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
12997 Don't access memory outside of the args array.
12998 (Fdefine_coding_system_internal): Check for charset-id overflow.
12999 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
13000 result of ENCODE_CHAR.
13001 * coding.h: Adjust decls to match defn changes elsewhere.
13002 (struct coding_system):

13690 2012-05-21 Ken Brown <kbrown@cornell.edu>
13692 * xgselect.c (xg_select): Fix first argument in call to 'select'
13695 2012-05-20 Ken Brown <kbrown@cornell.edu>
13697 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
13698 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
13700 2012-05-19 Ken Brown <kbrown@cornell.edu>
13702 * xfns.c (x_in_use): Remove `static' qualifier.
13703 * xterm.h (x_in_use): Declare.
13704 * xgselect.c: Include xterm.h.
13705 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
13706 and `display_arg' (bug#9754).
13708 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
13710 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
13712 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
13713 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
13715 2012-05-18 Eli Zaretskii <eliz@gnu.org>
13717 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
13719 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
13720 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
13722 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
13723 reference to image_cache->refcount.
13724 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
13726 2012-05-17 Juri Linkov <juri@jurta.org>
13728 * search.c (Fword_search_regexp, Fword_search_backward)
13729 (Fword_search_forward, Fword_search_backward_lax)
13730 (Fword_search_forward_lax): Move functions to isearch.el
13731 (bug#10145, bug#11381).
13733 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13735 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13737 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13739 * lread.c (init_obarray): Declare Qt and Qnil as special.
13741 2012-05-14 Glenn Morris <rgm@gnu.org>
13743 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13744 Put "libexec" before "bin", for the sake of init_callproc_1.
13746 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13748 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13750 * unexaix.c: Port to more-recent AIX compilers.
13751 (report_error, report_error_1, make_hdr, copy_sym)
13752 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13753 Make arguments const char *, not char *, to avoid violations of C
13754 standard and to fix some AIX warnings reported by Gilles Pion.
13756 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13758 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13759 already have overlays loaded.
13760 (handle_single_display_spec): Before returning without displaying
13761 fringe bitmap, synchronize the bidi iterator with the main display
13762 iterator, by calling iterate_out_of_display_property.
13763 (iterate_out_of_display_property): Detect buffer iteration by
13764 testing that it->string is a Lisp string.
13765 (get_next_display_element): When the current object is exhausted,
13766 and there's something on it->stack, call set_iterator_to_next to
13767 proceed with what's on the stack, instead of returning zero.
13768 (set_iterator_to_next): If called at the end of a Lisp string,
13769 proceed to consider_string_end without incrementing string
13770 position. Don't increment display vector index past the end of
13771 the display vector. (Bug#11417)
13772 (pos_visible_p): Don't report a position visible when move_it_to
13773 stopped at the last line of window, which happens to be scanned
13774 backwards by the bidi iteration. (Bug#11464)
13776 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13778 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13779 and right-margin display specs even if the spec is invalid or we
13780 are on a TTY, and thus unable to display on the fringes.
13781 That's because the text with the property will not be displayed anyway,
13782 so we need to signal to the caller that this is a "replacing"
13783 display spec. This fixes display when the spec is invalid or we
13786 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13788 * unexaix.c (make_hdr): Fix typo in prototype.
13789 This bug broke the build on AIX. Problem reported by Gilles Pion.
13791 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13793 * keyboard.c (kbd_buffer_get_event): Read special events also in
13794 batch mode. (Bug#11415)
13796 2012-05-12 Glenn Morris <rgm@gnu.org>
13798 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13800 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13802 * lisp.mk (lisp): Add newcomment.elc.
13804 2012-05-12 Glenn Morris <rgm@gnu.org>
13806 * Makefile.in (MKDIR_P): New, set by configure.
13807 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13809 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13811 Remove unused function hourglass_started.
13812 * dispextern.h (hourglass_started):
13813 * w32fns.c (hourglass_started):
13814 * xdisp.c (hourglass_started): Remove.
13816 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13818 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13819 Update dependencies.
13821 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13823 * xgselect.c (xg_select): Put maxfds+1 into a var.
13824 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13826 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13828 2012-05-10 Dave Abrahams <dave@boostpro.com>
13830 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13831 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13833 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13835 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13836 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13837 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13838 Initialize xd_registered_buses.
13840 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13842 Untag more efficiently if USE_LSB_TAG.
13843 This is based on a proposal by YAMAMOTO Mitsuharu in
13844 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13845 For an admittedly artificial (nth 8000 longlist) benchmark on
13846 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13847 Emacs's overall text size by 1%.
13848 * lisp.h (XUNTAG): New macro.
13849 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13850 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13851 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13852 * eval.c (Fautoload):
13853 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13854 * frame.h (XFRAME): Use XUNTAG.
13856 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13857 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13858 Remove unportable assumptions about print widths of types like
13860 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13861 intptr_t when converting between pointer and integer, to avoid GCC
13862 warnings about wrong width.
13864 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13866 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13867 stack for each reader_thread, instead of defaulting to 8MB
13868 determined by the linker. This avoids failures in creating
13869 subprocesses on Windows 7, see the discussion in this thread:
13870 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13872 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13874 Fix up display of the *Minibuf-0* buffer in the mini window.
13875 * keyboard.c (read_char): Don't clear the echo area if there's no
13877 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13878 contents of *Minibuf-0*) if there's no message displayed in its stead.
13880 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13882 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13885 2012-05-06 Chong Yidong <cyd@gnu.org>
13887 * lisp.mk (lisp): Update.
13889 2012-05-05 Jim Meyering <meyering@redhat.com>
13891 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13893 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13895 * data.c (PUT_ERROR): New macro.
13896 (syms_of_data): Use it. Add new error type `user-error'.
13897 * undo.c (user_error): New function.
13898 (Fprimitive_undo): Use it.
13899 * print.c (print_error_message): Adjust print style for `user-error'.
13900 * keyboard.c (user_error): New function.
13901 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13903 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13905 Do not limit current-time-string to years 1000..9999.
13906 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13907 (Fcurrent_time_string): Support any year that is supported by the
13908 underlying localtime representation. Don't use asctime, as it
13909 has undefined behavior for years outside the range -999..9999.
13911 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13913 Fix race conditions involving setenv, gmtime, localtime, asctime.
13914 Without this fix, interrupts could mess up code that uses these
13915 nonreentrant functions, since setting TZ invalidates existing
13916 tm_zone or tzname values, and since most of these functions return
13917 pointers to static storage.
13918 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13919 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13920 Grow the critical sections to include not just invoking
13921 localtime/gmtime, but also accessing these functions' results
13922 including their tm_zone values if any, and any related TZ setting.
13923 (format_time_string): Last arg is now struct tm *, not struct tm **,
13924 so that the struct tm is saved in the critical section.
13925 All callers changed. Simplify allocation of initial buffer, partly
13926 motivated by the fact that memory allocation needs to be outside
13927 the critical section.
13929 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13931 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13932 with RESET_INTERVAL.
13934 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13935 Remove duplicated buffer name initialization.
13937 2012-05-02 Jim Meyering <jim@meyering.net>
13939 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13941 * xfns.c (x_window): Use xstrdup (Bug#11375).
13943 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13945 * xdisp.c (pos_visible_p): If already at a newline from the
13946 display string before the 'while' loop, don't walk back the glyphs
13947 from it3.glyph_row. Solves assertion violation when the display
13948 string begins with a newline (egg.el). (Bug#11367)
13950 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13952 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13955 2012-05-01 Glenn Morris <rgm@gnu.org>
13957 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13958 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13959 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13960 All were removed before 23.1.
13962 * dispnew.c: Remove HAVE_LIBNCURSES test;
13963 it is always true on relevant platforms.
13965 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13966 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13968 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13970 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13972 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13973 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13976 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13978 Do not avoid creating empty evaporating overlays (Bug#9642).
13979 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13980 That is, do not delete an evaporating overlay if it becomes
13981 empty after its bounds are adjusted to fit within its buffer.
13982 This fix caused other problems, and I'm reverting it until we get
13983 to the bottom of them.
13985 2012-04-27 Chong Yidong <cyd@gnu.org>
13987 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13989 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13991 * xdisp.c (pos_visible_p): If the window start position is beyond
13992 ZV, start the display from buffer beginning. Prevents assertion
13993 violation in init_iterator when the minibuffer window is scrolled
13994 via the scroll bar.
13996 * window.c (window_scroll_pixel_based): Likewise.
13998 2012-04-27 Chong Yidong <cyd@gnu.org>
14000 * keymap.c (where_is_internal): Doc fix (Bug#10872).
14002 2012-04-27 Glenn Morris <rgm@gnu.org>
14004 * fileio.c (Fcopy_file, Fset_file_selinux_context):
14005 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
14007 2012-04-27 Eli Zaretskii <eliz@gnu.org>
14009 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
14010 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
14012 2012-04-26 Eli Zaretskii <eliz@gnu.org>
14014 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
14015 display element, check also the underlying string or buffer
14016 character. (Bug#11341)
14018 * w32menu.c: Include w32heap.h.
14019 (add_menu_item): If the call to AppendMenuW (via
14020 unicode_append_menu) fails, disable Unicode menus only if we are
14021 running on Windows 9X/Me.
14023 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
14025 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
14026 (xgetint): Add missing shift for LSB tags.
14028 2012-04-24 Martin Rudalics <rudalics@gmx.at>
14030 * keyboard.c (read_char): Don't wipe echo area for select window
14031 events: These might get delayed via `mouse-autoselect-window'
14034 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
14036 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
14037 manipulation of :loaded-from data.
14039 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
14041 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
14042 now a cons (bug#11311).
14044 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
14046 Do not create empty overlays with the evaporate property (Bug#9642).
14047 * buffer.c (Fmove_overlay): Delete an evaporating overlay
14048 if it becomes empty after its bounds are adjusted to fit within
14049 its buffer. Without this fix, in a nonempty buffer (let ((o
14050 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
14051 yields an empty overlay that has the evaporate property, which is
14052 not supposed to happen.
14054 Fix minor GTK3 problems found by static checking.
14055 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14056 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14057 (struct _EmacsFixedClass, emacs_fixed_get_type):
14058 Move decls here from emacsgtkfixed.h, since they needn't be public.
14059 (emacs_fixed_get_type): Now static.
14060 (emacs_fixed_class_init): Omit unused local.
14061 (emacs_fixed_child_type): Remove; unused.
14062 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
14063 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
14064 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
14065 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
14066 (EMACS_FIXED_GET_CLASS): Remove; unused.
14067 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
14069 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
14070 Problem reported by Juanma Barranquero for Windows -Wunused-function.
14072 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14074 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
14075 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
14076 (__malloc_size_t, __malloc_ptrdiff_t):
14077 Remove. All uses removed, replaced by the definiens if needed,
14078 since we can assume C89 or better now.
14079 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

14087 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
14088 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
14089 Define using prototypes, not old style.
14090 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
14091 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
14092 (align): Don't assume that signed integer overflow wraps around.
14093 Omit unused local var.
14094 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
14095 (_free_internal_nolock, memalign, mallochook, reallochook):
14096 Omit no-longer-needed casts.
14097 (valloc): Use getpagesize, not __getpagesize.
14098 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
14099 (struct hdr): The 'magic' member is now size_t, not unsigned long.
14101 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
14103 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
14105 Move functions from C to Lisp. Make non-blocking method calls
14106 the default. Implement further D-Bus standard interfaces.
14108 * dbusbind.c (DBUS_NUM_MESSAGE_TYPES): Declare.

14121 (XD_DBUS_VALIDATE_BUS_NAME, XD_DBUS_VALIDATE_PATH)
14122 (XD_DBUS_VALIDATE_INTERFACE, XD_DBUS_VALIDATE_MEMBER): New macros.
14123 (XD_CHECK_DBUS_SERIAL): Rename from CHECK_DBUS_SERIAL_GET_SERIAL.
14124 (xd_signature, xd_append_arg): Allow float for integer types.
14125 (xd_get_connection_references): New function.
14126 (xd_get_connection_address): Rename from xd_initialize.

14165 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
14167 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14169 * sysdep.c [__FreeBSD__]: Minor cleanups.
14170 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14171 Use Emacs indenting style more consistently. Avoid some casts.

14176 * sysdep.c (list_system_processes, system_process_attributes):
14177 Add implementation for FreeBSD (Bug#5243).

14183 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
14185 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
14186 It is never used otherwise.
14188 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
14190 * print.c (print_preprocess): Only check print_depth if print-circle
14192 (print_object): Check for cycles even when print-circle is nil and
14193 print-gensym is t, but only check print_depth if print-circle is nil.

14197 * process.c (wait_reading_process_output): If EIO occurs on a pty,
14198 set the status to "failed" and ensure that sentinel is run.
14200 2012-04-20 Glenn Morris <rgm@gnu.org>
14202 * process.c (Fset_process_inherit_coding_system_flag)
14203 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

14231 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
14232 -Wunused-result, -Wunused-variable. This should go away once
14233 the Emacs and Gnulib regex code is merged.
14234 (xmalloc, xrealloc): Now static.
14236 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

14253 New extern decls, to avoid calling undeclared functions.
14254 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14255 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14256 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14257 (NEED_MEM_INSERT): New macro.
14258 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14259 Remove one incorrect comment and fix another.

14274 Remove decls. This fixes an "It stinks!".
14276 * alloc.c (which_symbols): Fix alignment issue / type clash.
14278 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14280 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
14281 (struct Lisp_Misc_Any): Likewise.

14295 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14296 * s/netbsd.h, s/sol2-6.h:
14297 Remove definition of GC_MARK_STACK, since the default now works.
14298 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14299 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14300 no longer the default.
14301 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14303 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14305 * lread.c (lisp_file_lexically_bound_p):
14306 Fix hang at ";-*-\n" (bug#11238).
14308 2012-04-14 Eli Zaretskii <eliz@gnu.org>

14322 2012-04-13 Reuben Thomas <rrt@sc3d.org>
14324 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14326 2012-04-11 Daniel Colascione <dancol@dancol.org>
14328 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14329 against is gone. It's better to use vfork now so that when Cygwin
14330 gains a new, working vfork, we use it automatically (bug#10398).
14332 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
14334 * window.c (save_window_save): Obey window-point-insertion-type.

14352 * w32.c (w32_delayed_load): Record the full path of the library
14353 being loaded (bug#10424).
14355 2012-04-09 Glenn Morris <rgm@gnu.org>
14357 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14358 not just in the obarray, before snarfing them. (Bug#11036)

14375 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14376 attempts per process (connection).
14378 2012-04-09 Chong Yidong <cyd@gnu.org>
14380 * eval.c (Fuser_variable_p, user_variable_p_eh)

14382 (Fdefvar): Caller changed.
14384 * callint.c (Finteractive, Fcall_interactively):
14385 * minibuf.c (Fread_variable): Callers changed.
14387 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14389 * xdisp.c (set_cursor_from_row): If the display string appears in
14390 the buffer at position that is closer to point than the position
14391 after the display string, display the cursor on the first glyph of
14392 the display string. Fixes cursor display when a 'display' text
14393 property immediately follows invisible text. (Bug#11094)
14395 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14397 composite.c: use 'double' consistently
14398 * composite.c (get_composition_id): Use 'double' consistently
14399 instead of converting 'float' to 'double' and vice versa; this is
14400 easier to understand and avoids a GCC warning.
14402 2012-04-09 Glenn Morris <rgm@gnu.org>
14404 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14405 preparation for dumping it with emacs. (Bug#4789)

14427 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14428 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14429 objects, as mark_maybe_pointer will catch them otherwise.

14444 ($(BLD)/xml.$(O)): New dependency list.
14446 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14447 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14448 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14449 [!WINDOWSNT]: New macros.
14450 (init_libxml2_functions, libxml2_loaded_p): New functions.
14451 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14452 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14453 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14454 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14456 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14457 Call init_libxml2_functions before calling libxml2 functions.
14458 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14460 * emacs.c: Don't include libxml/parser.h.
14461 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14462 xmlCleanupParser directly.
14464 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14466 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14468 * indent.c (Fvertical_motion): If there is a display string at
14469 point, use it.vpos to compute how many lines to backtrack after
14470 move_it_to point. (Bug#11133)
14472 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14474 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14475 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14476 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14477 macros related to unification of CJK characters. For the details,
14478 see the discussion following the message here:
14479 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14481 2012-04-04 Chong Yidong <cyd@gnu.org>
14483 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14485 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14487 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

14495 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14497 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14498 position we get to after a call to move_it_to fails the
14499 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14500 only if we wind up in a string from display property. (Bug#11063)
14502 * window.c (Fdelete_other_windows_internal): Invalidate the row
14503 and column information about mouse highlight, so that redisplay
14504 restores it after reallocating the glyph matrices. (Bug#7464)
14506 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14507 string comes from a `display' text property, use the buffer
14508 position of that property as if we actually saw that position in
14510 (move_it_by_lines): Remove the assertion that
14511 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14512 violated when there's a before-string at the beginning of a line.
14515 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14517 * xdisp.c (append_space_for_newline): If the default face was
14518 remapped, use the remapped face for the appended newline.
14519 (extend_face_to_end_of_line): Use the remapped default face for
14520 extending the face to the end of the line.
14521 (display_line): Call extend_face_to_end_of_line when the default
14522 face was remapped. (Bug#11068)
14524 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14526 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14528 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

14544 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14545 (command_loop_1): Use it; inhibit selection update for

14550 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14552 2012-03-25 Kenichi Handa <handa@m17n.org>
14554 * dispextern.h (struct glyph): Change the bit length of
14555 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14557 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14559 * s/ms-w32.h (tzname): Include time.h before redirecting to

14568 !SYNC_INPUT. (Bug#11080)
14570 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14572 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14573 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14574 when fetching a multibyte character consumes more bytes than
14575 CHAR_BYTES returns, due to unification of CJK characters in
14576 string_char. (Bug#11073)
14578 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14580 * process.c (wait_reading_process_output): Handle pty disconnect

14610 it fit in a valid range (Bug#11003).
14612 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14614 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14615 that is not from display property, accept the row as a "cursor
14616 row" if one of the string's character has a non-nil `cursor'
14617 property. Fixes cursor positioning when there are newlines in
14618 overlay strings, e.g. in icomplete.el. (Bug#11035)
14620 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>

14654 2012-03-03 Glenn Morris <rgm@gnu.org>
14656 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14658 2012-03-02 Eli Zaretskii <eliz@gnu.org>

14671 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14673 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14674 push_it before setting up the iterator for the first overlay
14675 string, even if we have an empty string loaded.
14676 (next_overlay_string): If there's an empty string on the iterator
14677 stack, pop the stack. (Bug#10903)
14679 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14681 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14682 Suggested by Stefan Monnier in
14683 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14684 * alloc.c (widen_to_Lisp_Object): New static function.
14685 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14686 and widening them to Lisp_Objects. This would work even if
14687 USE_LSB_TAG is defined and wide integers are used, which might
14688 happen in a future version of Emacs.
14690 2012-02-25 Chong Yidong <cyd@gnu.org>
14692 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

14697 before saving to clipboard manager.
14699 2012-02-24 Chong Yidong <cyd@gnu.org>
14701 * keyboard.c (process_special_events): Handle all X selection
14702 requests in kbd_buffer, not just the next one (Bug#8869).
14704 2012-02-23 Chong Yidong <cyd@gnu.org>
14706 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14707 call when setting menu-bar-lines and tool-bar-lines parameters.
14708 (unwind_create_frame_1): New helper function.

14729 when computing $valmask.
14731 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14732 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14733 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14734 It's useless in that case, and it can cause problems on hosts
14735 that allocate halves of EMACS_INT values separately.
14736 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14737 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14738 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14739 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14740 it avoids undefined behavior on hosts where shifting right by more
14741 than the word width has undefined behavior.
14743 2012-02-19 Chong Yidong <cyd@gnu.org>
14745 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14746 (Funhandled_file_name_directory, Ffile_name_as_directory)
14747 (Fdirectory_file_name, Fexpand_file_name)
14748 (Fsubstitute_in_file_name): Protect against invalid file handler
14749 return values (Bug#10845).

14765 2012-02-15 Chong Yidong <cyd@gnu.org>
14767 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14768 marked as special. Also, starting docstrings with * is obsolete.

14783 2012-02-12 Chong Yidong <cyd@gnu.org>
14785 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14786 as that creates a dangerous corner case.
14788 * window.c (Fdelete_window_internal): Invalidate the mouse
14789 highlight (Bug#9904).
14791 2012-02-12 Glenn Morris <rgm@gnu.org>

14796 * nsselect.m (Fx_own_selection_internal)
14797 (Fx_disown_selection_internal, Fx_selection_exists_p)
14798 (Fx_selection_owner_p, Fx_get_selection_internal):
14799 Sync docs and argument specs with the xselect.c versions.
14801 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

14821 2012-02-07 Chong Yidong <cyd@gnu.org>
14823 * buffer.c (Fbuffer_local_variables)
14824 (buffer_lisp_local_variables): Handle unbound vars correctly;
14825 don't let Qunbound leak into Lisp.
14827 2012-02-07 Glenn Morris <rgm@gnu.org>
14829 * image.c (Fimagemagick_types): Doc fix.
14831 * image.c (imagemagick-render-type): Change it from a lisp object
14832 to an integer. Move the doc here from the lisp manual.

14866 Handle overflow when computing char display width (Bug#9496).
14867 * character.c (char_width): Return EMACS_INT, not int.
14868 (char_width, c_string_width): Check for overflow when
14869 computing the width; this is possible now that individual
14870 characters can have unbounded width. Problem introduced
14871 by merge from Emacs 23 on 2012-01-19.

14895 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
14897 (x_produce_glyphs): If the component of a composition is a null
14898 string, set it->pixel_width to 1 to avoid zero-width glyph.

14902 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14903 first 2 arguments are identical. This makes inserting large
14904 output from a subprocess an order of magnitude faster on
14905 MS-Windows, where all sbrk'ed memory is always contiguous.
14907 2012-01-31 Glenn Morris <rgm@gnu.org>

15000 Update template values to be closer to their typical values these days.
15002 2012-01-09 Eli Zaretskii <eliz@gnu.org>
15004 * xdisp.c (rows_from_pos_range): Accept additional argument
15005 DISP_STRING, and accept any glyph in a row whose object is that
15006 string as eligible for mouse highlight. Fixes mouse highlight of
15007 display strings from overlays. (Bug#10464)
15009 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
15011 emacs: fix an auto-save permissions race condition (Bug#10400)

15013 (Fmake_directory_internal): Use it.
15014 (do_auto_save_make_dir): Set it, instead of invoking chmod after

15018 (Fdo_auto_save): Catch all errors, not just file errors, so
15019 that the var is always cleared.

15520 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
15521 Otherwise, valgrind does not work on some platforms.
15522 Problem reported by Andreas Schwab in
15523 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
15524 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15525 is set, removing the need for VIRT_ADDRESS_VARIES.
15526 (PURE_P): Use a more-efficient implementation that needs just one
15527 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
15528 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
15529 to 4 (xorl, subq, cmpq, setbe).
15530 * alloc.c (pure): Always extern now, since that's the
15531 VIRT_ADDR_VARIES behavior.
15532 (PURE_POINTER_P): Use a single comparison, not two, for
15533 consistency with the new puresize.h.
15534 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

15995 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
15997 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
15999 2011-10-28 Eli Zaretskii <eliz@gnu.org>
16001 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
16002 <oslsachem@gmail.com> for helping to debug this.
16004 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
16005 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
16006 (g_b_init_get_glyph_outline_w): New static variables.
16007 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
16008 (GetGlyphOutlineW_Proc): New typedefs.
16009 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
16010 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
16012 (w32font_open_internal, compute_metrics):
16013 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
16014 instead of calling the "wide" APIs directly.
16016 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
16018 * w32.h (syms_of_w32font): Add prototype.
16020 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16022 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
16023 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
16024 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
16025 (Fmove_to_window_line): Doc fix.
16027 2011-10-27 Chong Yidong <cyd@gnu.org>
16029 * process.c (make_process): Set gnutls_state to NULL.
16031 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
16032 non-NULL, regardless of GNUTLS_INITSTAGE.
16033 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
16034 an error. Set process slots as soon as we allocate them.
16036 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
16038 2011-10-27 Chong Yidong <cyd@gnu.org>
16040 * gnutls.c (emacs_gnutls_deinit): New function.
16041 Deallocate credentials structures as well as calling gnutls_deinit.
16042 (Fgnutls_deinit, Fgnutls_boot): Use it.
16044 * process.c (make_process): Initialize GnuTLS credentials to NULL.
16045 (deactivate_process): Call emacs_gnutls_deinit.
16047 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
16049 * image.c (x_create_x_image_and_pixmap):
16050 * w32.c (sys_rename, w32_delayed_load):
16051 * w32font.c (fill_in_logfont):
16052 * w32reg.c (x_get_string_resource): Silence compiler warnings.
16054 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
16056 * w32fns.c (w32_default_color_map): New function,
16057 extracted from Fw32_default_color_map.
16058 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
16060 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
16062 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
16064 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
16066 * keyboard.c (test_undefined): New function (bug#9751).
16067 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
16069 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
16071 * sysdep.c (init_sys_modes): Fix the check for the controlling
16072 terminal (Bug#6649).
16074 2011-10-20 Eli Zaretskii <eliz@gnu.org>
16076 * dispextern.h (struct bidi_it): New member next_en_type.
16078 * bidi.c (bidi_line_init): Initialize the next_en_type member.
16079 (bidi_resolve_explicit_1): When next_en_pos is valid for the
16080 current character, check also for next_en_type being WEAK_EN.
16081 (bidi_resolve_weak): Don't enter the expensive loop if the current
16082 position is before next_en_pos. Record the bidi type of the first
16083 non-ET, non-BN character we find, in addition to its position.
16084 (bidi_level_of_next_char): Invalidate next_en_type when
16085 next_en_pos is over-stepped.
16087 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
16089 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16090 * editfns.c: Rewrite current-time-zone so that it invokes
16091 the equivalent of (format-time-string "%Z") to get the time zone name.
16092 This fixes a bug when the time zone name contains characters that
16093 need converting from the system time locale to Emacs internal format.
16094 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16095 that patch fixed format-time-string to do the conversion, but
16096 I forgot to fix current-time-zone.
16097 (format_time_string): New function, containing most of
16098 what Fformat_time_string used to contain.
16099 (Fformat_time_string): Rewrite in terms of format_time_string.
16100 This doesn't change this function's behavior.
16101 (current-time-zone): Rewrite to use format_time_string.
16102 This fixes the bug reported by Michael Schierl in
16103 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16104 Jason Rumney's 2007-06-07 change worked around this bug, but
16106 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16108 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16110 * xdisp.c (start_display): If the character at POS is displayed
16111 via a display vector, reset IT->current.dpvec_index to zero.
16112 (try_window_reusing_current_matrix): If a line ends in a display
16113 vector or the next line starts in a display vector, continue
16114 redrawing the window even though the character position of
16115 start_row was reached.
16118 2011-10-18 Chong Yidong <cyd@gnu.org>
16120 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16121 with nobreak-char-display too.
16123 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16125 Fix part 3 of bug#9771.
16126 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16127 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16128 non-neutral characters if the current character is a paragraph
16129 separator (a.k.a. Newline). This avoids running the same
16130 expensive loop twice, once when we consume the preceding newline
16131 and the other time when the line actually needs to be displayed.
16132 Avoid the loop when we see neutrals on the base embedding level
16133 following a character whose directionality is the same as the
16134 paragraph's. This avoids running the expensive loop when a line
16135 ends in a long sequence of neutrals, like control characters.
16136 Add assertion against STRONG_AL type. Slightly rearrange code
16137 that determines the type of a neutral given the first non-neutral
16139 (bidi_level_of_next_char): Set next_en_pos to zero when
16140 invalidating its info.
16142 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16144 * xdisp.c (push_display_prop): Determine whether to record string
16145 or buffer position by IT->string, not by IT->method. Allow
16146 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16147 (move_it_vertically_backward): Don't look for character position
16148 immediately after the newline when in a continuation line.
16151 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16153 * window.c (coordinates_in_window): Rewrite and delabelize
16154 vertical border check. (Bug#5357) (Bug#9618)
16156 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16158 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16159 errors in XSetWindowBorder (bug#9310).
16161 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16163 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16164 avoid crash when xmalloc overrun checking is enabled.
16166 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16168 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16169 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16170 cursor motion with <left> and <right> arrow keys.
16172 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16173 some callers set that themselves.
16175 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16177 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16178 display string and the previous row comes from the same string and
16179 is empty. (Bug#9739) (Bug#9738)
16181 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16183 * doc.c (get_doc_string): Encode file name (bug#9735).
16185 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16187 * bidi.c (bidi_level_of_next_char):
16188 * xdisp.c (get_visually_first_element): Remove old incorrect
16189 comments regarding the Unicode Line Separator character.
16191 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16193 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16195 * alloc.c (Fgc_status): Do not access beyond zombies array
16196 boundary if nzombies > MAX_ZOMBIES.
16197 * alloc.c (dump_zombies): Add missing format specifier.
16199 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16201 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16202 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16204 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16205 Some packages use them to denote characters with modifiers.
16207 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16209 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16210 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16211 matching a pp-number. Rename parameter var to var1.
16213 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16215 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16217 2011-10-08 Glenn Morris <rgm@gnu.org>
16219 * callint.c (Fcall_interactively): Give a more explicit error for the
16220 'c' case with a non-character input. (Bug#8479)
16222 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16224 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16226 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16227 lines that are hscrolled on the left.
16229 * dispnew.c (buffer_posn_from_coords): Account for a possible
16230 presence of header-line. (Bug#4426)
16232 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16234 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16235 Don't advertise functionality which we discourage or doesn't work.
16237 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16239 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16240 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16241 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16242 this makes Emacs dump core during garbage collection on rare
16243 occasions. sizeof is obviously inferior to offsetof here, so
16244 stick with offsetof.
16245 (GC_POINTER_ALIGNMENT): New macro.
16246 (mark_memory): Omit 3rd (offset) arg; caller changed.
16247 Don't assume EMACS_INT alignment is the same as pointer alignment.
16249 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16251 * keyboard.c (read_key_sequence_remapped): New var.
16252 (read_key_sequence): Compute remapping in the right buffer.
16253 (command_loop_1): Use read_key_sequence's remapping directly.
16255 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16257 * dired.c (file_name_completion): Don't expand file name.
16258 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16259 before checking file name handler.
16261 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16262 they've been requested explicitly (bug#9591).
16264 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16266 * keymap.c (Fsingle_key_description): Use make_specified_string
16267 instead of build_string to build string from push_key_description.
16270 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16272 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16273 This fixes a Y2038 bug on 64-bit hosts.
16274 * buffer.c (reset_buffer):
16275 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16276 (Fclear_buffer_auto_save_failure):
16277 Use 0, not -1, to represent an unset failure time, since time_t
16278 might not be signed.
16280 Remove dependency on glibc malloc internals.
16281 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16282 Move back here from lisp.h, but with their new implementations.
16283 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16284 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16285 * charset.c (charset_table_init): New static var.
16286 (syms_of_charset): Use it instead of xmalloc. This removes a
16287 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16288 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16289 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16290 Move back to alloc.c.
16291 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16292 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16294 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16296 * nsterm.m (windowDidResize): Call x_set_window_size only when
16297 ns_in_resize is true. Otherwise set pixelwidth/height and
16298 call change_frame_size (Bug#9628).
16300 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16302 Port --enable-checking=all to Fedora 14 x86-64.
16303 * charset.c (syms_of_charset): Also account for glibc malloc's
16304 internal overhead when calculating the initial malloc maximum.
16306 Port --enable-checking=all to Fedora 14 x86.
16307 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16309 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16310 (overrun_check_realloc, overrun_check_free):
16311 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16312 That way, xmalloc returns a properly-aligned pointer even if
16313 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16314 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16315 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16316 into account when calculating the initial malloc maximum.
16317 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16318 Move here from alloc.c, so that charset.c can use it too.
16319 Properly align; the old code wasn't right for common 32-bit hosts
16320 when configured with --enable-checking=all.
16321 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16322 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16324 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16326 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16329 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16331 * xdisp.c (compute_display_string_end): If there's no display
16332 string at CHARPOS, return -1.
16334 * bidi.c (bidi_fetch_char): When compute_display_string_end
16335 returns a negative value, treat the character as a normal
16336 character not covered by a display string. (Bug#9624)
16338 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16340 * lread.c (Fread_from_string): Fix typo in docstring.
16342 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16344 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16345 newline, reseat the iterator instead of bidi-iterating there one
16346 character at a time. (Bug#9610)
16347 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16348 TO_CHARPOS if the bidi iterator is at base embedding level.
16350 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16352 * lread.c (readevalloop): Use correct code for NBSP.
16353 (read1): Likewise. (Bug#9608)
16355 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16357 * dbusbind.c (Fdbus_register_signal): When service is not
16358 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16360 2011-09-25 Glenn Morris <rgm@gnu.org>
16362 * buffer.c (truncate-lines): Doc fix.
16364 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16366 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16367 (Fset_window_next_buffers): Doc fix.
16369 2011-09-24 Glenn Morris <rgm@gnu.org>
16371 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16373 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16375 Fix minor problems found by static checking.
16376 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16377 * indent.c (Fvertical_motion): Fix == vs = typo.
16379 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16381 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16382 Default value is now t. Doc fix.
16384 * indent.c (Fvertical_motion): Compute and apply the overshoot
16385 logic when moving up, not only when moving down. Fix the
16386 confusing name and values of the it_overshoot_expected variable;
16387 logic changes accordingly. (Bug#9254) (Bug#9549)
16389 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16390 CHARPOS is covered by a display string which includes newlines.
16391 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16392 is covered by a display string with embedded newlines.
16394 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16396 * dbusbind.c (Fdbus_register_signal): Add match rule to
16397 Vdbus_registered_objects_table. (Bug#9581)
16398 (Fdbus_register_method, Vdbus_registered_objects_table):
16401 2011-09-24 Jim Meyering <meyering@redhat.com>
16403 do not ignore write error for any output size
16404 The previous change was incomplete.
16405 While it makes emacs --batch detect the vast majority of stdout
16406 write failures, errors were still ignored whenever the output size is
16407 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16408 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16409 && echo FAIL: ignored write error
16410 FAIL: ignored write error
16411 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16412 && echo FAIL: ignored write error
16413 FAIL: ignored write error
16414 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16416 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16418 * emacs.c (Fkill_emacs): In noninteractive mode exit
16419 non-successfully if a write error occurred on stdout. (Bug#9574)
16421 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16423 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16426 * dispextern.h (struct it): Update the comment documenting what
16429 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16431 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16432 a display string, extend search for cursor position to end of row.
16433 (find_row_edges): If the row ends in a newline from a display
16434 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16435 Handle the case of a display string with multiple newlines.
16436 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16437 non-empty line. Fixes confusing cursor motion with arrow keys at
16438 the beginning of a line that starts with whitespace.
16440 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16442 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16445 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16447 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16448 boolean (Bug#9154).
16450 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16452 * xdisp.c (display_line): Record maximum and minimum buffer
16453 positions even if no glyphs were produced (e.g., by a zero-width
16454 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16455 buffer positions that will be removed from the glyph row because
16457 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16458 column is beyond frame width: don't subtract 1 "pixel" when
16459 computing width of the stretch.
16460 (reseat_at_next_visible_line_start): Undo the change made on
16461 2011-09-17 that saved paragraph information and restored it after
16462 the call to `reseat'. (Bug#9545)
16464 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16466 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16467 and turn window cursor on if cleared (Bug#9415).
16469 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16471 * search.c (boyer_moore): Take unibyte characters from pattern
16472 literally. (Bug#9458)
16474 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16476 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16478 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16480 Fix minor problem found by static checking.
16481 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16482 initialized, to pacify gcc -Wuninitialized.
16484 * fileio.c: Report proper errno when syscall falls.
16485 (Finsert_file_contents): Save and restore errno,
16486 so that report_file_error outputs the correct diagnostic.
16487 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16489 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16491 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16493 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16495 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16496 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16498 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16500 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16501 about the current paragraph and restore it after the call to reseat.
16503 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16504 (bidi_find_paragraph_start): Search back for paragraph beginning
16505 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16506 (bidi_move_to_visually_next): Only trigger paragraph-related
16507 computations when the last character is a newline or at EOB, not
16508 just any NEUTRAL_B. (Bug#9470)
16510 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16511 truncated lines if point is covered by a display string. (Bug#9524)
16513 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16515 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16516 (cons_to_x_long): New function.
16517 (lisp_data_to_selection_data): Use it. Correct the test for
16518 short-versus-long data; it was negated. Break out of vector
16519 loop, for efficiency, when a long datum is discovered.
16521 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16523 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16525 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16527 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16528 GCC PR/17406) by declaring this function with external scope.
16530 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16532 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16533 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16535 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16537 * editfns.c (Fformat): Correctly handle text properties on "%%".
16539 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16541 * xterm.c (x_draw_composite_glyph_string_foreground):
16542 * w32term.c (x_draw_composite_glyph_string_foreground):
16543 * term.c (encode_terminal_code):
16544 * composite.c (composition_update_it, get_composition_id):
16545 * xdisp.c (get_next_display_element)
16546 (fill_composite_glyph_string): Add comments about special meaning
16547 of TAB characters in a composition.
16549 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16551 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16552 This occurs when processing a multibyte format.
16553 Problem reported by Wolfgang Jenker.
16555 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16557 * xdisp.c (try_cursor_movement): Only check for exact match if
16558 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16560 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16562 Remove unused external symbols.
16563 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16564 * xdisp.c (calc_pixel_width_or_height): Now static.
16565 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16566 * indent.c (check_display_width):
16567 * w32term.c: Fix comment to match code.
16568 * xterm.c, xterm.h (x_catching_errors): Remove.
16570 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16572 * xselect.c: Use signed conversions more consistently (Bug#9498).
16573 (selection_data_to_lisp_data): Assume incoming selection data are
16574 signed integers, not unsigned. This is to be consistent with
16575 outgoing selection data, which was modified to use signed integers
16576 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16577 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16578 expects long, not unsigned long.
16580 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16582 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16583 computation of loop end. Reported by Johan Bockgård
16586 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16588 * frame.c (Fother_visible_frames_p): Function deleted.
16590 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16592 * indent.c (compute_motion): Process display vector front to back
16593 rather than the other way around. (Bug#2496)
16595 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16597 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16599 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16601 * minibuf.c (Fread_from_minibuffer): Doc fix.
16603 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16605 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16606 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16608 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16610 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16611 value for non-existent files.
16613 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16615 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16616 set its "size" to -1. This will set the modtime_size field of
16617 the corresponding buffer to -1, which is what
16618 verify-visited-file-modtime expects for files that do not exist.
16621 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16623 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16625 * lisp.h: ... from here. push_key_description is no longer
16626 defined in keyboard.c, so its declaration should not be in
16627 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16628 logically belongs with push_key_description.
16630 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16632 * buffer.h: Include <sys/types.h> instead of <time.h>.
16633 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16634 Problem reported by Herbert J. Skuhra.
16636 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16638 * xml.c (parse_region): Make the parsing work for
16639 non-comment-starting XML files again (bug#9144).
16641 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16643 * image.c (gif_load): Fix calculation of bottom and right corner.
16646 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16648 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16649 redisplay in small windows.
16651 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16653 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16655 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16657 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16658 Operate on live windows only.
16660 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16662 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16664 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16666 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16667 only under bidi iteration.
16669 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16671 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16673 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16675 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16676 Without this fix, the command to link temacs failed due to an
16677 undefined symbol __builtin_isnan. This is because
16678 /usr/include/iso/math_c99.h #defines isnan(x) to
16679 __builtin_isnan(x), but the bundled gcc, which identifies itself
16680 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16682 * floatfns.c (isnan): #undef, and then #define to a clone of
16684 (Fisnan): Always define, since it's always available now.
16685 (syms_of_floatfns): Always define isnan at the Lisp level.
16687 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16689 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16691 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16693 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16694 The previous code assumed that file offsets (off_t values) fit in
16695 EMACS_INT variables, which is not true on typical 32-bit hosts.
16696 The code messed up by falsely reporting buffer overflow in cases
16697 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16698 when "big" contains more than 2**29 bytes, even though this
16699 inserts just one byte and does not overflow the buffer.
16700 (Finsert_file_contents): Store file offsets as off_t
16701 values, not as EMACS_INT values. Check for overflow when
16702 converting between EMACS_INT and off_t. When checking for
16703 buffer overflow or for overlap, take the offsets into account.
16704 Don't use EMACS_INT for small values where int suffices.
16705 When checking for overlap, fix a typo: ZV was used where
16706 ZV_BYTE was intended.
16707 (Fwrite_region): Don't assume off_t fits into 'long'.
16708 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16710 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16712 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16714 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16716 sprintf-related integer and memory overflow issues (Bug#9412).
16718 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16719 (esprintf, exprintf, evxprintf): New functions.
16720 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16721 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16722 (modify_event_symbol): Do not assume that the length of
16723 name_alist_or_stem is safe to alloca and fits in int.
16724 (Fexecute_extended_command): Likewise for function name and binding.
16725 (Frecursion_depth): Wrap around reliably on integer overflow.
16726 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16727 since some callers pass EMACS_INT values.
16728 (Fsingle_key_description): Don't crash if symbol name contains more
16729 than MAX_ALLOCA bytes.
16730 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16731 (get_minibuffer): Arg is now EMACS_INT, not int.
16732 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16733 (esprintf, exprintf, evxprintf): New decls.
16734 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16736 * dbusbind.c (signature_cat): New function.
16737 (xd_signature, Fdbus_register_signal):
16738 Do not overrun buffer; instead, report string overflow.
16740 * dispnew.c (add_window_display_history): Don't overrun buffer.
16741 Truncate instead; this is OK since it's just a log.
16743 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16744 even if the time zone offset is outlandishly large.
16745 Don't mishandle offset == INT_MIN.
16747 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16748 when creating daemon; the previous buffer-overflow check was incorrect.
16750 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16751 which has the guts of the old verror function.
16753 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16754 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16756 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16757 (font_unparse_xlfd): Don't blindly alloca long strings.
16758 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16759 fits in int, when using sprintf. Use single snprintf to count
16760 length of string rather than counting it via multiple sprintfs;
16761 that's simpler and more reliable.
16762 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16763 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16764 sprintf, in case result does not fit in int.
16766 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16767 (fontset_from_font): Print it.
16769 * frame.c (tty_frame_count): Now printmax_t, not int.
16770 (make_terminal_frame, set_term_frame_name): Print it.
16771 (x_report_frame_params): In X, window IDs are unsigned long,
16772 not signed long, so print them as unsigned.
16773 (validate_x_resource_name): Check for implausibly long names,
16774 and don't assume name length fits in 'int'.
16775 (x_get_resource_string): Don't blindly alloca invocation name;
16776 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16779 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16780 (xg_check_special_colors, xg_set_geometry):
16781 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16783 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16784 Use esprintf, not sprintf, in case result does not fit in int.
16786 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16787 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16788 it as a large positive number.
16789 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16790 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16792 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16793 in case result does not fit in int.
16795 * print.c (float_to_string): Detect width overflow more reliably.
16796 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16797 buffer overrun. Don't assume list length fits in 'int'. Treat
16798 print length of 0 as 0, not as infinity; to be consistent with other
16799 uses of print length in this function. Don't overflow print length
16800 index. Don't assume hash table size fits in 'long', or that
16801 vectorlike size fits in 'unsigned long'.
16803 * process.c (make_process): Use printmax_t, not int, to format
16804 process-name gensyms.
16806 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16808 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16809 to avoid potential buffer overrun.
16811 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16812 if X resource line is longer than 512 bytes.
16814 * xfns.c (x_window): Make sprintf buffer a bit bigger
16815 to avoid potential buffer overrun.
16817 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16819 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16821 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16823 Integer overflow fixes for scrolling, etc.
16824 Without these, Emacs silently mishandles large integers sometimes.
16825 For example, "C-u 4294967297 M-x recenter" was treated as if
16826 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16828 * xdisp.c (try_window_id): Check Emacs fixnum range before
16829 converting to 'int'.
16831 * window.c (window_scroll_line_based, Frecenter):
16832 Check that an Emacs fixnum is in range before assigning it to 'int'.
16833 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16834 values converted from Emacs fixnums.
16835 (Frecenter): Don't wrap around a line count if it is out of 'int'
16836 range; instead, treat it as an extreme value.
16837 (Fset_window_configuration, compare_window_configurations):
16838 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16840 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16841 that can exceed INT_MAX. Check that EMACS_INT value is in range
16842 before assigning it to the (possibly-narrower) index.
16843 (match_limit): Don't assume that a fixnum can fit in 'int'.
16845 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16848 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16849 (Fvertical_motion): Don't wrap around LINES values that don't fit
16850 in 'int'. Instead, treat them as extreme values. This is good
16851 enough for windows, which can't have more than INT_MAX lines anyway.
16853 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16855 * Require libxml/parser.h to avoid compilation warning.
16857 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16859 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16860 since this reportedly can destroy thread storage.
16862 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16864 * syntax.c (find_defun_start): Update all cache variables if
16865 exiting early (Bug#9401).
16867 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16869 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16871 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16872 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16873 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16875 * term.c (tty_append_glyph): New function.
16876 (produce_stretch_glyph): Static function and its prototype deleted.
16878 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16881 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16883 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16884 when checking :margin (Bug#9390).
16885 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16886 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16887 so that the name doesn't mislead. All uses changed.
16889 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16891 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16894 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16896 * xdisp.c (move_it_to): Don't bail out early when reaching
16897 position beyond to_charpos, if we are scanning backwards.

16899 the first character in the line after the newline.
16901 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16903 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16904 (ccl_driver): Do not generate an out-of-range pointer.
16905 (Fccl_execute_on_string): Remove unnecessary check for
16906 integer overflow, noted by Stefan Monnier in
16907 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16908 Remove a FIXME that didn't need fixing.
16909 Simplify the newly-introduced buffer reallocation code.
16911 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16913 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16915 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16917 Integer and memory overflow issues (Bug#9196).
16919 * doc.c (get_doc_string): Rework so that
16920 get_doc_string_buffer_size is the actual buffer size, rather than
16921 being 1 less than the actual buffer size; this makes xpalloc more
16924 * image.c (x_allocate_bitmap_record, cache_image):
16925 * xselect.c (Fx_register_dnd_atom):
16926 Simplify previous changes by using xpalloc.
16928 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16929 since either will do and ptrdiff_t is convenient with xpalloc.
16931 * charset.c (charset_table_size)
16932 (struct charset_sort_data.priority): Now ptrdiff_t.
16933 (charset_compare): Don't overflow if priorities differ greatly.
16934 (Fsort_charsets): Don't assume list length fits in int.
16935 Check for size-calculation overflow when allocating sort data.
16936 (syms_of_charset): Allocate an initial charset table that is
16937 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16939 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16941 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16942 The actual value is always <= INT_MAX, and leaving it unsigned made
16943 overflow checking harder.
16945 * dispextern.h (struct glyph_matrix.rows_allocated)
16946 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16947 with xpalloc. The values are still always <= INT_MAX.
16949 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16951 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16952 (SAFE_NALLOCA): New macro.
16954 * region-cache.c (struct boundary.pos, find_cache_boundary)
16955 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16956 (set_cache_region, invalidate_region_cache)
16957 (revalidate_region_cache, know_region_cache, region_cache_forward)
16958 (region_cache_backward, pp_cache):
16959 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16960 so that ptrdiff_t * can be passed to xpalloc.
16961 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16962 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16963 (pp_cache): Don't assume cache_len fits in int.
16964 * region-cache.h: Adjust extern decls to match.
16966 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16967 EMACS_INT, since either will do, for xpalloc.
16969 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16970 (xnmalloc, xnrealloc, xpalloc): New functions.
16972 * bidi.c (bidi_shelve_header_size): New constant.
16973 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16974 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16976 * bidi.c (bidi_cache_shrink):
16977 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16979 Don't update size of array until after memory allocation succeeds,
16980 because xmalloc/xrealloc may not return.
16981 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16982 now that we have proper integer overflow checking.
16983 (record_overlay_string, overlay_strings): Catch overflows when
16984 calculating size of overlay_str_buf.
16986 * callproc.c (Fcall_process): Check for size overflow when
16987 calculating size of args2.
16988 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16989 Normally we prefer signed values, but sticking with ptrdiff_t would
16990 require adding more-complicated checks.
16992 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16993 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16994 Redo buffer-overflow calculations to avoid integer overflow.
16995 Add a FIXME comment where memory seems to be over-allocated.
16997 * character.c (Fstring): Check for size-calculation overflow.
16999 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
17000 unnecessary integer overflow. Check for size overflow.
17001 (encode_coding_object): Don't update size until xmalloc succeeds.
17003 * composite.c (get_composition_id): Check for overflow in glyph
17004 length calculations.
17006 Integer and memory overflow fixes for display code.
17007 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
17008 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
17009 (scrolling_window): Check for overflow in size calculations.

17021 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
17022 (get_doc_string): Check for size calculation overflow.
17023 Don't update size until allocation succeeds.
17024 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
17025 EMACS_INT, where ptrdiff_t will do.
17026 (Fsubstitute_command_keys): Check for string overflow.
17028 * editfns.c (set_time_zone_rule): Don't assume environment length
17030 (message_length): Now ptrdiff_t, not int.
17031 (Fmessage_box): Don't update size until allocation succeeds.
17032 Don't assume message length fits in int.
17033 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
17035 * emacs.c (main): Do not reallocate argv, since there is a null at
17036 the end that can be overwritten, and this way there's no need to
17037 worry about size-calculation overflow.
17038 (sort_args): Check for size-calculation overflow.
17040 * eval.c (init_eval_once, grow_specpdl): Don't update size until
17042 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
17044 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
17045 (x_set_scroll_bar_width, x_figure_window_size):
17046 Check for integer overflow.
17047 (x_set_alpha): Do not assume XINT fits in int.
17049 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
17050 This is for the members text_lines, text_cols, total_lines, total_cols,
17051 where the system imposes an 'int' limit.
17053 * fringe.c (Fdefine_fringe_bitmap):
17054 Don't update size until alloc works.
17056 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
17057 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
17059 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
17060 Check for size-calculation overflow.
17061 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
17062 do, as we prefer signed integers.
17063 (id_to_widget.max_size, id_to_widget.used)
17064 (xg_store_widget_in_map, xg_remove_widget_from_map)
17065 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
17066 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
17067 Use and return ptrdiff_t, not int.
17068 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
17069 * gtkutil.h: Change prototypes to match the above.
17071 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
17072 are duplicate now that they've been promoted to lisp.h.
17073 (x_allocate_bitmap_record, x_alloc_image_color)
17074 (make_image_cache, cache_image, xpm_load):

17088 calculations. Don't update size until allocation succeeds.
17089 Redo calculations to avoid overflow.

17118 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
17119 for command line length. Do not attempt to address one before the
17120 beginning of an array, as that's not portable.
17122 * term.c (max_frame_lines): Remove; unused.
17123 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
17125 (encode_terminal_code, calculate_costs): Check for size
17126 calculation overflow.

17132 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
17133 subtracting pointers.
17134 (gobble_line): Check for overflow more carefully. Don't update size
17137 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
17138 Don't update size until alloc done.

17148 Use ptrdiff_t, not int, for sizes.
17149 (Finternal_make_lisp_face, cache_face):
17150 Check for size calculation overflow.
17151 (cache_face): Treat size calculation overflows as if they were
17152 memory exhaustion (the usual treatment), rather than aborting.
17154 * xfns.c (x_encode_text, x_set_name_internal)
17155 (Fx_change_window_property): Use ptrdiff_t, not int, to count
17156 sizes, since they can exceed INT_MAX in size. Check for size

17160 (xg_select): Check for size calculation overflow.
17161 Don't update size until alloc done.
17163 * xrdb.c (get_environ_db): Don't assume path length fits in int,
17164 as sprintf is limited to int lengths.
17166 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17167 (X_LONG_MIN): New macros.
17168 Use them to make the following changes clearer.
17169 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17170 This change doesn't affect the value now, but it may help remind
17171 future maintainers not to raise the value too much later.
17172 (SELECTION_QUANTUM): Remove, replacing with ...
17173 (selection_quantum): ... new function, which avoids overflow.
17175 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17176 assumption that selection length fits in 'int'.

17189 (lisp_data_to_selection_data, x_property_data_to_lisp):

17193 Don't store size until memory allocation succeeds.
17194 (x_get_window_property): Plug memory leak on memory exhaustion.
17195 Don't double-block input; malloc is safe here. Don't assume 2**34
17196 - 4 fits in unsigned long. Add an xassert to check
17197 XGetWindowProperty overflow. Be more careful about overflow
17198 calculations, and distinguish size from memory overflow better.
17199 (receive_incremental_selection): When tracing, don't assume
17200 unsigned int is less than INT_MAX.
17201 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
17202 harmful) conversions of unsigned short to int.
17203 (lisp_data_to_selection_data): Don't assume that integers
17204 in the range -65535 through -1 fit in an X unsigned short.
17205 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17206 result parameters unless successful. Rely on cons_to_unsigned
17207 to report problems with elements; the old code wasn't right anyway.
17208 (x_check_property_data): Check for int overflow; we cannot use
17209 a wider type due to X limits.
17210 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

17242 * lisp.h (hash_lookup, hash_put):
17243 * minibuf.c (Ftest_completion):
17244 Use ptrdiff_t for hash table indexes, not int (which is too
17245 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17246 32-bit --with-wide-int hosts).
17248 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17249 Add a FIXME comment about memory leaks.
17250 (syms_of_charset): Don't assume xmalloc returns.

17254 * character.h (CHAR_WIDTH):
17255 * indent.c (MULTIBYTE_BYTES_WIDTH):
17256 Use sanitize_char_width to avoid undefined and/or bad behavior
17257 with outlandish widths.
17258 * character.h (sanitize_tab_width): Rename from sanitize_width,
17259 now that we have two such functions. All uses changed.
17260 (sanitize_char_width): New inline function.
17262 Don't assume that tab-width fits in int.
17263 * character.h (sanitize_width): New inline function.

17280 exceed limits imposed by XClientMessageEvent, as well as the usual
17281 ptrdiff_t and size_t limits.
17283 * keyboard.c: Overflow, signedness and related fixes.
17284 (make_lispy_movement): Use same integer type in forward decl
17285 that is used in the definition.
17286 (read_key_sequence, keyremap_step):
17287 Change bufsize argument back to int, undoing my 2011-03-30 change.
17288 We prefer signed types, and int is wide enough here.
17289 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17290 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17291 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17292 length, not size_t. Use ptrdiff_t for index, not int.
17293 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17294 possibility of integer overflow.
17296 Overflow, signedness and related fixes for images.

17306 * xdisp.c (calc_pixel_width_or_height):
17307 * xfns.c (image_cache_refcount):
17308 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

17317 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
17318 (lookup_image): Remove unnecessary tests.
17319 (xbm_image_p): Locals are now of int, not EMACS_INT,
17320 since parse_image_check makes sure they fit into int.
17321 (png_load, gif_load, svg_load_image):
17322 Prefer int to unsigned where either will do.
17323 (tiff_handler): New function, combining the cores of the
17324 old tiff_error_handler and tiff_warning_handler.
17325 This function is rewritten to use vsnprintf and thereby avoid
17326 stack buffer overflows. It uses only the features of vsnprintf
17327 that are common to both POSIX and native Microsoft.
17328 (tiff_error_handler, tiff_warning_handler): Use it.
17329 (tiff_load, gif_load, imagemagick_load_image):
17330 Don't assume :index value fits in 'int'.
17331 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17332 (imagemagick_load_image): Check that crop parameters fit into
17333 the integer types that MagickCropImage accepts. Don't assume
17334 Vimagemagick_render_type has a nonnegative value. Don't assume
17335 size_t fits in 'long'.
17336 (gs_load): Use printmax_t to print the widest integers possible.
17337 Check for integer overflow when computing image height and width.

17350 (handle_single_display_spec): If the display spec is of the form
17351 `(space ...)', and specifies display in the text area, return 2
17353 (try_cursor_movement): Check for the need to scroll more
17354 accurately, and prefer exact match for point under bidi.
17355 Don't advance `row' beyond the last row of the window.

17376 positioning on the newline at EOL of R2L text within L2R
17377 paragraph, and vice versa.
17378 (try_cursor_movement): Check continued rows, in addition to
17379 continuation rows. Fixes unwarranted scroll when point enters a
17380 continued line of R2L text within an L2R paragraph, or vice versa.
17381 (cursor_row_p): Consider the case of point being equal to
17382 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17383 from the end of a short line to the beginning of a continued line
17384 of R2L text within L2R paragraph.

17408 * xdisp.c (redisplay_window): When computing centering_position,
17409 account for the height of the header line. (Bug#8874)
17411 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17412 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17413 candidate is selected by the mouse, and that candidate has a
17414 composed character under the mouse.
17416 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17417 coordinates reported by pos-visible-in-window-p for a composed
17418 character in column zero.

17427 consider it a hit if to_charpos is anywhere in the range of the
17428 composed buffer positions.
17430 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17432 * image.c (gif_load): Don't assume that each subimage has the same
17433 dimensions as the base image. Handle disposal method that is
17434 "undefined" by the gif spec (Bug#9335).
17436 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17438 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17443 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17444 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17445 from an Org mode buffer to a Speedbar frame.
17447 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17448 a composition, take its buffer position from IT->cmp_it.charpos.
17449 Fixes cursor positioning at the beginning of a line that begins
17450 with a composed character.
17452 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17454 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17455 character bidirectional type, use STRONG_L instead. Fixes crashes
17456 in a buffer produced by `describe-categories'.
17458 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17459 members before the level stack, so they would be saved and
17460 restored when copying iterator state. Fixes incorrect reordering
17461 around TABs covered by display properties.
17463 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

17551 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17552 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17553 the event loop (Bug#7276).

17596 buffer/string position, to be restored by pop_it. Fix flags in
17597 the iterator structure wrt the object coming from a display
17598 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17599 properties. (Bug#9284)

17797 instead of hard-coded value of 2.
17798 (nsfont_draw): Call ns_draw_text_decoration instead.
17800 * nsterm.h: Add declaration for ns_draw_text_decoration.
17802 * nsterm.m (ns_draw_text_decoration): New function for drawing
17803 underline, overline, and strike-through.
17804 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17805 ns_draw_text_decoration. Change treatment of cursor drawing to
17806 accommodate underlining, etc.
17808 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17810 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17813 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17815 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17816 Without this fix, if a signal arrives just after memory fills up,
17817 'malloc' might be invoked reentrantly.
17819 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17820 In other words, assume that every image size is allowed, on non-X
17821 hosts. This assumption is probably wrong, but it lets Emacs compile.
17823 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17825 * regex.c (re_iswctype): Convert return values to boolean.
17827 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17829 * xdisp.c (compute_display_string_pos): Don't use cached display
17830 string position if the buffer had its restriction changed.
17833 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17835 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17837 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17839 Integer signedness and overflow and related fixes. (Bug#9079)
17841 * bidi.c: Integer size and overflow fixes.
17842 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17843 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17844 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17845 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17846 (bidi_find_other_level_edge):
17847 Use ptrdiff_t instead of EMACS_INT where either will do.
17848 This works better on 32-bit hosts configured --with-wide-int.
17849 (bidi_cache_ensure_space): Check for size-calculation overflow.
17850 Use % rather than repeated addition, for better worst-case speed.
17851 Don't set bidi_cache_size until after xrealloc returns, because it
17853 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17854 (bidi_cache_ensure_space): Also check that the bidi cache size
17855 does not exceed that of the largest Lisp string or buffer. See Eli
17856 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17858 * alloc.c (__malloc_size_t): Remove.
17859 All uses replaced by size_t. See Andreas Schwab's note
17860 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17862 * image.c: Improve checking for integer overflow.
17863 (check_image_size): Assume that f is nonnull, since
17864 it is always nonnull in practice. This is one less thing to
17865 worry about when checking for integer overflow later.
17866 (x_check_image_size): New function, which checks for integer
17867 overflow issues inside X.
17868 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17869 This removes the need for a memory_full check.
17870 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17871 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17872 (xbm_read_bitmap_data): Change locals back to 'int', since
17873 their values must fit in 'int'.
17874 (xpm_load_image, png_load, tiff_load):
17875 Invoke x_create_x_image_and_pixmap earlier,
17876 to avoid much needless work if the image is too large.
17877 (tiff_load): Treat overly large images as if
17878 x_create_x_image_and_pixmap failed, not as malloc failures.
17879 (gs_load): Use x_check_image_size.
17881 * gtkutil.c: Omit integer casts.
17882 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17883 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17885 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17887 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17888 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17889 would wrongly return t on a 64-bit host.
17891 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17892 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17893 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17894 and therefore cause GCC to emit a bogus diagnostic in some cases.
17896 * image.c: Integer signedness and overflow and related fixes.
17897 This is not an exhaustive set of fixes, but it's time to
17898 record what I've got.
17899 (lookup_pixel_color, check_image_size): Remove redundant decls.
17900 (check_image_size): Don't assume that arbitrary EMACS_INT values
17901 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17902 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17903 (tiff_load, imagemagick_load_image):
17904 Check for overflow in size calculations.
17905 (x_create_x_image_and_pixmap): Remove unnecessary test for
17906 xmalloc returning NULL; that can't happen.
17907 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17908 (xpm_color_bucket): Use better integer hashing function.
17909 (xpm_cache_color): Don't possibly over-allocate memory.
17910 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17911 (gif_memory_source):
17912 Use ptrdiff_t, not int or size_t, to record sizes.
17913 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17914 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17915 either works, as we prefer signed integers.
17916 (tiff_read_from_memory, tiff_write_from_memory):
17917 Return tsize_t, not size_t, since that's what the TIFF API wants.
17918 (tiff_read_from_memory): Don't fail simply because the read would
17919 go past EOF; instead, return a short read.
17920 (tiff_load): Omit no-longer-needed casts.
17921 (Fimagemagick_types): Don't assume size fits into 'int'.
17923 Improve hashing quality when configured --with-wide-int.
17924 * fns.c (hash_string): New function, taken from sxhash_string.
17925 Do not discard information about ASCII character case; this
17926 discarding is no longer needed.
17927 (sxhash-string): Use it. Change sig to match it. Caller changed.
17928 * lisp.h: Declare it.
17929 * lread.c (hash_string): Remove, since we now use fns.c's version.
17930 The fns.c version returns a wider integer if --with-wide-int is
17931 specified, so this should help the quality of the hashing a bit.
17933 * emacs.c: Integer overflow minor fix.
17934 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17935 Define only if GNU_LINUX.
17936 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17938 * dispnew.c: Integer signedness and overflow fixes.
17939 Remove unnecessary forward decls, that were a maintenance hassle.
17940 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17942 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17943 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17944 (prepare_desired_row, line_draw_cost):
17945 Use int, not unsigned, where either works.
17946 (save_current_matrix, restore_current_matrix):
17947 Use ptrdiff_t, not size_t, where either works.
17948 (init_display): Check for overflow more accurately, and without
17949 relying on undefined behavior.
17951 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17952 Remove, replacing with the new symbols in lisp.h. All uses changed.
17953 * fileio.c (make_temp_name):
17954 * filelock.c (lock_file_1, lock_file):
17955 * xdisp.c (message_dolog):
17956 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17957 Use pMd etc. instead.
17958 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17959 replacing the pWIDE etc. symbols removed from editfns.c.
17961 * keyboard.h (num_input_events): Now uintmax_t.
17962 This is (very slightly) less likely to mess up due to wraparound.
17965 * buffer.c: Integer signedness fixes.
17966 (alloc_buffer_text, enlarge_buffer_text):
17967 Use ptrdiff_t rather than size_t when either will do, as we prefer
17970 * alloc.c: Integer signedness and overflow fixes.
17971 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17972 (__malloc_size_t): Default to size_t, not to int.
17973 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17974 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17975 Prefer ptrdiff_t to size_t when either would do, as we prefer
17977 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17978 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17979 Now const. Initialize with values that are in range even if char
17981 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17982 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17983 These functions do the right thing with sizes > 2**32.
17984 (check_depth): Now ptrdiff_t, not int.
17985 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17986 Adjust to new way of storing sizes. Check for size overflow bugs
17988 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17989 slightly wrong anyway, as it missed one instance of
17990 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17991 (refill_memory_reserve): Omit needless cast to size_t.
17992 (mark_object_loop_halt): Mark as externally visible.
17994 * xselect.c: Integer signedness and overflow fixes.
17995 (Fx_register_dnd_atom, x_handle_dnd_message):
17996 Use ptrdiff_t, not size_t, since we prefer signed.
17997 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17998 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17999 x_dnd_atoms_size and x_dnd_atoms_length.
18001 * doprnt.c: Prefer signed to unsigned when either works.
18003 * doprnt.c (doprnt):
18005 * xdisp.c (vmessage):
18006 Use ptrdiff_t, not size_t, when using or implementing doprnt,
18007 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
18008 prefer signed arithmetic to avoid comparison confusion.
18009 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
18010 but is a bit tricky.
18012 Assume freestanding C89 headers, string.h, stdlib.h.
18013 * data.c, doprnt.c, floatfns.c, print.c:
18014 Include float.h unconditionally.
18015 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
18016 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
18017 * regex.c: Likewise for stddef.h, string.h.
18018 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
18019 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
18020 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
18021 (STDC_HEADERS): Remove obsolete defines.
18022 * sysdep.c: Include limits.h unconditionally.
18024 Assume support for memcmp, memcpy, memmove, memset.
18025 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
18026 * regex.c (memcmp, memcpy):
18027 Remove; we assume C89 now.
18029 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
18030 (__malloc_safe_bcopy): Remove; no longer needed.
18032 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
18033 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
18034 well either way, and we prefer signed to unsigned.
18036 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
18038 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
18039 closes the connection while we're reading (bug#9182).
18041 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
18043 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
18044 are specified (Bug#9168).
18046 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
18048 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
18049 Found by GCC static checking and --with-wide-int on a 32-bit host.
18051 2011-07-25 Eli Zaretskii <eliz@gnu.org>
18053 * xdisp.c (compute_display_string_pos): Fix logic of caching
18054 previous display string position. Initialize cached_prev_pos to
18055 -1. Fixes slow-down at the beginning of a buffer.
18057 2011-07-24 Eli Zaretskii <eliz@gnu.org>
18059 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
18060 for attrs[LFACE_FONTSET_INDEX].
18062 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
18064 * xml.c (parse_region): Remove unused local
18065 that was recently introduced.
18067 2011-07-23 Eli Zaretskii <eliz@gnu.org>
18069 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
18070 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
18072 * xdisp.c (move_it_in_display_line_to): Record the best matching
18073 position for TO_CHARPOS while scanning the line, and restore it on
18074 exit if none of the characters scanned was an exact match.
18075 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
18076 when exact match is impossible due to invisible text, and the
18077 lines are truncated.
18079 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18081 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18084 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18086 Fix a significant slow-down of cursor motion with C-n, C-p,
18087 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18088 auto-repeat under bidi redisplay in fontified buffers.
18089 * xdisp.c (compute_stop_pos_backwards): New function.
18090 (next_element_from_buffer): Call compute_stop_pos_backwards to
18091 find a suitable prev_stop when we find ourselves before
18093 (reseat): Don't look for prev_stop, as that could mean a very long
18095 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18096 <cached_disp_overlay_modiff>: Cache for last found display string
18098 (compute_display_string_pos): Return the cached position if asked
18099 about the same buffer in the same area of character positions, and
18100 the buffer wasn't changed since the time the display string
18101 position was cached.
18103 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18105 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18106 is an integer, which is important for empty lines. (Bug#9149)
18108 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18110 * frame.c (Fmodify_frame_parameters): In tty case, update the
18111 default face if necessary (Bug#4238).
18113 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18115 * editfns.c (Fstring_to_char): No need to explain what a character
18116 is in the docstring (Bug#6576).
18118 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18120 * xml.c (parse_region): Make sure we always return a tree.
18122 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18124 * xml.c (parse_region): If a document contains only comments,
18127 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18129 * xml.c (make_dom): Return comments, too.
18131 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18134 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18135 and the surrounding thread.
18136 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18137 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18138 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18140 * s/openbsd.h (BROKEN_SIGIO): Define.
18141 * unexelf.c (unexec) [__OpenBSD__]:
18142 Don't update the .mdebug section of the Alpha COFF symbol table.
18144 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18146 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18149 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18151 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18152 This fixes some race conditions on the permissions of any newly
18155 * alloc.c (valid_pointer_p): Use pipe, not open.
18156 This fixes some permissions issues when debugging.
18158 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18159 If fchown fails to set both uid and gid, try to set just gid,
18160 as that is sometimes allowed. Adjust the file's mode to eliminate
18161 setuid or setgid bits that are inappropriate if fchown fails.
18163 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18165 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18166 to compare Lisp_Objects.
18167 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18168 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18169 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18171 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18173 * lread.c (read_integer): Unread even EOF character.
18174 (read1): Likewise. Properly record start position of symbol.
18176 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18177 symbol character follows.
18179 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18181 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18182 This works around a problem with the previous change to Fcopy_file.
18183 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18184 and without this change, GCC might complain about discarding
18185 fchown's return value.
18187 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18189 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18191 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18193 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18195 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18197 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18198 it's used from the C level.
18200 * process.c: Use the same condition for POLL_FOR_INPUT in both
18201 keyboard.c and process.c (bug#1858).
18203 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18205 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18206 (Fgnutls_boot): Use it.
18208 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18210 * doc.c (Fsubstitute_command_keys): Revert last change.
18212 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18214 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18215 quotes the next character, and doesn't affect other longer
18216 sequences (bug#8935).
18218 * lread.c (syms_of_lread): Clarify that is isn't only
18219 `eval-buffer' and `eval-defun' that's affected by
18220 `lexical-binding' (bug#8460).
18222 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18224 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18225 bidi redisplay when a line includes both an image and is truncated.
18227 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18229 Fix minor problems found by static checking.
18230 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18231 (elsz): Now a signed constant, not a size_t var. We prefer signed
18232 types to unsigned, to avoid integer comparison confusion. Without
18233 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18234 "cannot optimize loop, the loop counter may overflow", a symptom
18236 * indent.c (Fvertical_motion): Mark locals as initialized.

18761 (clone_per_buffer_values): Don't assume that

18765 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18766 New macros, used in the buffer.c change.

18802 Random fixes. E.g., (random) never returned negative values.
18803 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18804 subseconds part to the entropy, as that's a bit more random.
18805 Prefer signed to unsigned, since the signedness doesn't matter and
18806 in general we prefer signed. When given a limit, use a
18807 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18808 latter isn't right if USE_2_TAGS_FOR_INTS.
18809 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18810 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18822 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18823 This is more efficient than Ffile_directory_p and avoids a minor race.

18827 * buffer.c (Foverlay_put): Say what the return value is
18830 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18831 is a directory before asking whether to use the file name

18834 error be more correct.
18836 * fns.c (Frequire): Remove the mention of the .gz files, since
18837 that's installation-specific, but keep the mention of
18838 `get-load-suffixes'.

18850 Qgnutls_bootprop_verify_error (which is no longer used).
18852 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18853 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18854 Also (re)move comments that are misplaced or no longer relevant.
18856 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
18858 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

18883 * lread.c (syms_of_lread): Mention single symbols defined by

18886 * fns.c (Frequire): Mention .el.gz files (bug#7314).
18887 (Frequire): Mention get-load-suffixes.

18917 (syms_of_keymap): Defsubr make-composed-keymap.
18918 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

18955 * eval.c (struct backtrace): Simplify and port the data structure.
18956 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18957 signed bit field, as this assumption is not portable and it makes
18958 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18959 "char debug_on_exit : 1" as this is not portable either; instead,
18960 use the portable "unsigned int debug_on_exit : 1". Remove unused
18961 member evalargs. Remove obsolete comments about cc bombing out.
18963 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

19115 * xfaces.c (syms_of_xfaces):
19116 * xfns.c (syms_of_xfns):
19117 * xmenu.c (syms_of_xmenu):
19118 * xsettings.c (syms_of_xsettings):
19119 * xterm.c (syms_of_xterm): Use DEFSYM.
19121 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
19123 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
19125 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
19127 Integer and buffer overflow fixes (Bug#8873).
19129 * print.c (printchar, strout): Check for string overflow.
19130 (PRINTPREPARE, printchar, strout):
19131 Don't set size unless allocation succeeds.
19133 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
19134 for sizes. Check for string overflow more accurately.
19135 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
19137 * macros.c: Integer and buffer overflow fixes.
19138 * keyboard.h (struct keyboard.kbd_macro_bufsize):
19139 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
19140 Use ptrdiff_t, not int, for sizes.
19141 Don't increment bufsize until after realloc succeeds.
19142 Check for size-calculation overflow.
19143 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
19145 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
19147 * lread.c: Integer overflow fixes.
19148 (read_integer): Radix is now EMACS_INT, not int,
19149 to improve quality of diagnostics for out-of-range radices.
19150 Calculate buffer size correctly for out-of-range radices.
19151 (read1): Check for integer overflow in radices, and in
19152 read-circle numbers.
19153 (read_escape): Avoid int overflow.
19154 (Fload, openp, read_buffer_size, read1)
19155 (substitute_object_recurse, read_vector, read_list, map_obarray):
19156 Use ptrdiff_t, not int, for sizes.
19157 (read1): Use EMACS_INT, not int, for sizes.
19158 Check for size overflow.
19160 * image.c (cache_image): Check for size arithmetic overflow.

19169 (read_escape): Check for hex character overflow.
19171 2011-06-22 Leo Liu <sdl.web@gmail.com>
19173 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
19174 Move to minibuffer.el.
19176 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19178 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19179 The following patches are for when GLYPH_DEBUG && !XASSERT.
19180 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19181 * dispnew.c (flush_stdout):
19182 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19183 Mark as externally visible.
19184 * dispnew.c (check_window_matrix_pointers): Now static.
19185 * dispnew.c (window_to_frame_vpos):
19186 * xfns.c (unwind_create_frame):
19187 * xterm.c (x_check_font): Remove unused local.
19188 * scroll.c (CHECK_BOUNDS):
19189 * xfaces.c (cache_fache): Rename local to avoid shadowing.
19190 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
19191 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
19192 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
19193 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19195 (debug_method_add): Use va_list and vsprintf rather than relying
19196 on undefined behavior with wrong number of arguments.
19197 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19198 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19199 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19200 since we're not interested in debugging glyphs with old libraries.
19201 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19202 GCC 4.6.0's static checking.
19204 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19206 Integer overflow and signedness fixes (Bug#8873).

19215 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
19216 (x_create_bitmap_from_xpm_data):
19217 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
19218 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
19220 * xfaces.c (load_pixmap):
19221 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
19222 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
19223 (.bitmaps_last, struct x_output.icon_bitmap):
19224 Use ptrdiff_t, not int, for bitmap indexes.
19225 (x_allocate_bitmap_record): Check for size overflow.
19226 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19228 Use ptrdiff_t, not int, for overlay counts.
19229 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19230 * editfns.c (overlays_around, get_pos_property):
19231 * textprop.c (get_char_property_and_overlay):
19232 * xdisp.c (next_overlay_change, note_mouse_highlight):
19233 * xfaces.c (face_at_buffer_position):
19234 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19235 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19236 (Fnext_overlay_change, Fprevious_overlay_change)
19237 (mouse_face_overlay_overlaps, Foverlays_in):
19238 Use ptrdiff_t, not int, for sizes.
19239 (overlays_at, overlays_in): Check for size-calculation overflow.
19241 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19243 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19244 (x_session_initialize): Do not assume string length fits in int.
19246 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19247 This is unlikely, but can occur if DPI is outlandish.
19249 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19250 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19252 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19253 * xrdb.c (magic_file_p, search_magic_path):
19254 Omit last arg SUFFIX; it was always 0. All callers changed.
19255 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19257 * xfont.c (xfont_match): Avoid need for strlen.
19259 * xfns.c: Don't assume strlen fits in int.
19260 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19262 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19263 not unsigned long, as we prefer signed integers. All callers changed.
19264 Detect integer overflow in repeat count.
19265 (message_dolog): Don't assume print length fits in 39 bytes.
19266 (display_mode_element): Don't assume strlen fits in int.
19268 * termcap.c: Don't assume sizes fit in int and never overflow.
19269 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19270 (gobble_line): Check for size-calculation overflow.
19272 * minibuf.c (Fread_buffer):
19273 * lread.c (intern, intern_c_string):
19274 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19275 Don't assume string length fits in int.
19277 * keyboard.c (parse_tool_bar_item):
19278 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19280 * font.c: Don't assume string length fits in int.
19281 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19282 Use ptrdiff_t, not int.
19283 (font_intern_prop): Don't assume string length fits in int.
19284 Don't assume integer property fits in fixnum.
19285 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19287 * filelock.c: Fix some buffer overrun and integer overflow issues.
19288 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19289 Reformulate so as not to need the command string.
19290 Invoke gzip -cd rather than gunzip, as it's more portable.
19291 (lock_info_type, lock_file_1, lock_file):
19292 Don't assume pid_t and time_t fit in unsigned long.
19293 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19294 (current_lock_owner): Prefer signed type for sizes.
19295 Use memcpy, not strncpy, where memcpy is what is really wanted.
19296 Don't assume (via atoi) that time_t and pid_t fit in int.
19297 Check for time_t and/or pid_t out of range, e.g., via a network share.
19298 Don't alloca where an auto var works fine.
19300 * fileio.c: Fix some integer overflow issues.
19301 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19302 Don't assume string length fits in int.
19303 (directory_file_name): Don't assume string length fits in long.
19304 (make_temp_name): Don't assume pid fits in int, or that its print
19305 length is less than 20.
19307 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19309 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19311 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19313 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19314 We prefer signed integers, even for size calculations.
19316 * emacs.c: Don't assume string length fits in 'int'.
19317 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19318 (main): Don't invoke strlen when not needed.
19320 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19321 (XD_DEBUG_MESSAGE): Don't waste a byte.
19323 * callproc.c (getenv_internal_1, getenv_internal)
19324 (Fgetenv_internal):
19325 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19327 * lread.c (invalid_syntax): Omit length argument.
19328 All uses changed. This doesn't fix a bug, but it simplifies the
19329 code away from its former Hollerith-constant appearance, and it's
19330 one less 'int' to worry about when looking at integer-overflow issues.
19331 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19333 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19334 This didn't break anything, but it didn't help either.
19335 It's confusing to put a bogus integer in a place where the actual
19336 value does not matter.
19337 (LIST_END_P): Remove unused macro and its bogus comment.
19338 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19340 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19341 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19343 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19344 We prefer signed types, and the value cannot exceed the EMACS_INT
19345 range anyway (because otherwise the length would not be representable).
19346 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19347 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19348 This avoids a GCC warning when WIDE_EMACS_INT.
19350 * indent.c (sane_tab_width): New function.
19351 (current_column, scan_for_column, Findent_to, position_indentation)
19352 (compute_motion): Use it. This is just for clarity.
19353 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19355 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19357 * lisp.h (lint_assume): New macro.
19358 * composite.c (composition_gstring_put_cache):
19359 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19361 * editfns.c, insdel.c:
19362 Omit unnecessary forward decls, to simplify future changes.
19364 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19366 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19368 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19369 Use much-faster test for byte-length change.
19370 Don't assume string byte-length fits in 'int'.
19371 Check that character arg fits in 'int'.
19372 (mapcar1): Declare byte as byte, for clarity.
19374 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19376 * fns.c (concat): Catch string overflow earlier.
19377 Do not rely on integer wraparound.
19379 * dispextern.h (struct it.overlay_strings_charpos)
19380 (struct it.selective): Now EMACS_INT, not int.
19381 * xdisp.c (forward_to_next_line_start)
19382 (back_to_previous_visible_line_start)
19383 (reseat_at_next_visible_line_start, next_element_from_buffer):
19384 Don't arbitrarily truncate the value of 'selective' to int.
19386 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19388 * composite.c: Don't truncate sizes to 'int'.
19389 (composition_gstring_p, composition_reseat_it)
19390 (composition_adjust_point): Use EMACS_INT, not int.
19391 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19392 not EMACS_UINT, for indexes.
19394 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19396 * buffer.c: Include <verify.h>.
19397 (struct sortvec.priority, struct sortstr.priority):
19398 Now EMACS_INT, not int.
19399 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19400 (struct sortstr.size, record_overlay_string)
19401 (struct sortstrlist.size, struct sortlist.used):
19402 Don't truncate size to int.
19403 (record_overlay_string): Check for size-calculation overflow.
19404 (init_buffer_once): Check at compile-time, not run-time.
19406 2011-06-22 Jim Meyering <meyering@redhat.com>
19408 Don't leak an XBM-image-sized buffer
19409 * image.c (xbm_load): Free the image buffer after using it.
19411 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19414 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19415 that Sun C diagnosed.
19416 * fns.c (secure_hash): Fix pointer signedness issue.
19417 * intervals.c (static_offset_intervals): New function.
19418 (offset_intervals): Use it.
19420 2011-06-21 Leo Liu <sdl.web@gmail.com>
19423 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19426 * fns.c (secure_hash): Rename from crypto_hash_function and change
19427 the first arg to accept symbols.
19428 (Fsecure_hash): New primitive.
19429 (syms_of_fns): New symbols.
19431 2011-06-20 Deniz Dogan <deniz@dogan.se>
19433 * process.c (Fset_process_buffer): Clarify return value in
19436 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19438 * dispnew.c (add_window_display_history): Use BVAR.
19440 * xdisp.c (debug_method_add): Use BVAR.
19441 (check_window_end, dump_glyph_matrix, dump_glyph)
19442 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19444 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19447 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19448 check till after the cache is created in init_frame_faces.
19450 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19452 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19454 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19456 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19457 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19458 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19460 Improve buffer-overflow checking (Bug#8873).
19461 * fileio.c (Finsert_file_contents):
19462 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19463 Remove the old (too-loose) buffer overflow checks.
19464 They weren't needed, since make_gap checks for buffer overflow.
19465 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19466 The old code merely checked for Emacs fixnum overflow, and relied
19467 on undefined (wraparound) behavior. The new code avoids undefined
19468 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19470 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19471 Tune. Don't use wider integers than needed. Don't use alloca.
19472 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19474 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19476 * insdel.c, lisp.h (buffer_overflow): New function.
19477 (insert_from_buffer_1, replace_range, replace_range_2):
19478 * insdel.c (make_gap_larger):
19479 * editfns.c (Finsert_char):
19480 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19482 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19484 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19486 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19488 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19489 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19491 * fileio.c: Don't assume EMACS_INT fits in off_t.
19492 (emacs_lseek): New static function.
19493 (Finsert_file_contents, Fwrite_region): Use it.
19494 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19496 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19498 * fns.c: Don't overflow int when computing a list length.
19499 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19500 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19501 truncation on 64-bit hosts. Check for QUIT every
19502 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19503 faster and is responsive enough.
19504 (Flength): Report an error instead of overflowing an integer.
19505 (Fsafe_length): Return a float if the value is not representable
19506 as a fixnum. This shouldn't happen except in contrived situations.
19507 (Fnthcdr, Fsort): Don't assume list length fits in int.
19508 (Fcopy_sequence): Don't assume vector length fits in int.
19510 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19511 (header_size, word_size): New constants.
19512 (allocate_vectorlike): Don't check size overflow here.
19513 (allocate_vector): Check it here instead, since this is the only
19514 caller of allocate_vectorlike that could cause overflow.
19515 Check that the new vector's length is representable as a fixnum.
19517 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19518 The previous code was bogus. For example, next_almost_prime (32)
19519 returned 39, which is undesirable as it is a multiple of 3; and
19520 next_almost_prime (24) returned 25, which is a multiple of 5 so
19521 why was the code bothering to check for multiples of 7?
19523 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19525 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19527 Variadic C functions now count arguments with ptrdiff_t.
19528 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19529 Back then I didn't know that the Emacs coding style prefers signed int.
19530 Also, in the meantime I found a few more instances where arguments
19531 were being counted with int, which may truncate counts on 64-bit
19532 machines, or EMACS_INT, which may be unnecessarily wide.
19533 * lisp.h (struct Lisp_Subr.function.aMANY)
19534 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19535 Arg counts are now ptrdiff_t, not size_t.
19536 All variadic functions and their callers changed accordingly.
19537 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19538 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19539 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19540 * callint.c (Fcall_interactively): Check arg count for overflow,
19541 to avoid potential buffer overrun. Use signed char, not 'int',
19542 for 'varies' array, so that we needn't bother to check its size
19543 calculation for overflow.
19544 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19545 * eval.c (apply_lambda):
19546 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19547 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19548 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19550 * callint.c (Fcall_interactively): Don't use index var as event count.
19552 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19553 * mem-limits.h (SIZE): Remove; no longer used.
19555 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19557 Remove unnecessary casts.
19558 * xterm.c (x_term_init):
19559 * xfns.c (x_set_border_pixel):
19560 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19561 These aren't needed now that we assume ANSI C.
19563 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19564 It's more likely to cause problems (due to unsigned overflow)
19567 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19569 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19571 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19573 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19575 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19577 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19579 GLYPH_CODE_FACE returns EMACS_INT, not int.
19580 * dispextern.h (merge_faces):
19581 * xfaces.c (merge_faces):
19582 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19583 Don't assume EMACS_INT fits in int.
19585 * character.h (CHAR_VALID_P): Remove unused parameter.
19586 * fontset.c, lisp.h, xdisp.c: All uses changed.
19588 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19590 * fns.c (concat): Minor tuning based on overflow analysis.
19591 This doesn't fix any bugs. Use int to hold character, instead
19592 of constantly refetching from Emacs object. Use XFASTINT, not
19593 XINT, for value known to be a character. Don't bother comparing
19594 a single byte to 0400, as it's always less.
19596 * floatfns.c (Fexpt):
19597 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19599 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19602 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19604 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19605 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19606 incorrectly succeed when S was a string, because 4294967386 was
19607 truncated before it was used.
19609 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19610 Otherwise, an out-of-range integer could cause undefined behavior
19613 * composite.c: Use int, not EMACS_INT, for characters.
19614 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19615 EMACS_INT, for values that are known to be in character range.
19616 This doesn't fix any bugs but is the usual style inside Emacs and
19617 may generate better code on 32-bit machines.
19619 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19620 This is for reasons similar to the recent CHAR_STRING fix.
19621 * charset.c (Fencode_char): Check that character arg is actually
19622 a character. Pass an int to ENCODE_CHAR.
19623 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19624 wider than 'int', as a compile-time check to prevent future regressions
19627 * character.c (char_string): Remove unnecessary casts.
19629 Make sure a 64-bit char is never passed to CHAR_STRING.
19630 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19631 by silently ignoring the top 32 bits, allowing some values
19632 that were far too large to be valid characters.
19633 * character.h: Include <verify.h>.
19634 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19635 arguments are no wider than unsigned, as a compile-time check
19636 to prevent future regressions in this area.
19638 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19639 (Fsubst_char_in_region):
19641 * xdisp.c (decode_mode_spec_coding):
19642 Adjust to CHAR_STRING's new requirement.
19643 * editfns.c (Finsert_char, Fsubst_char_in_region):
19644 * fns.c (concat): Check that character args are actually
19645 characters. Without this test, these functions did the wrong
19646 thing with wildly out-of-range values on 64-bit hosts.
19648 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19649 These casts should not be needed on 32-bit hosts, either.
19650 * keyboard.c (read_char):
19651 * lread.c (Fload): Remove casts to unsigned.
19653 * lisp.h (UNSIGNED_CMP): New macro.
19654 This fixes comparison bugs on 64-bit hosts.
19655 (ASCII_CHAR_P): Use it.
19656 * casefiddle.c (casify_object):
19657 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19658 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19659 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19660 * dispextern.h (FACE_FROM_ID):
19661 * keyboard.c (read_char): Use UNSIGNED_CMP.
19663 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19664 not to EMACS_INT, to avoid GCC warning.
19666 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19668 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19669 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19670 isn't needed on 32-bit machines.
19672 * buffer.c (Fgenerate_new_buffer_name):
19673 Use EMACS_INT for count, not int.
19674 (advance_to_char_boundary): Return EMACS_INT, not int.
19676 * data.c (Qcompiled_function): Now static.
19678 * window.c (window_body_lines): Now static.
19680 * image.c (gif_load): Rename local to avoid shadowing.
19682 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19683 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19684 * alloc.c (make_save_value): Integer argument is now of type
19685 ptrdiff_t, not int.
19686 (mark_object): Use ptrdiff_t, not int.
19687 * lisp.h (pD): New macro.
19688 * print.c (print_object): Use it.
19690 * alloc.c: Use EMACS_INT, not int, to count objects.
19691 (total_conses, total_markers, total_symbols, total_vector_size)
19692 (total_free_conses, total_free_markers, total_free_symbols)
19693 (total_free_floats, total_floats, total_free_intervals)
19694 (total_intervals, total_strings, total_free_strings):
19695 Now EMACS_INT, not int. All uses changed.
19696 (Fgarbage_collect): Compute overall total using a double, so that
19697 integer overflow is less likely to be a problem. Check for overflow
19698 when converting back to an integer.
19699 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19700 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19701 These were 'int' variables that could overflow on 64-bit hosts;
19702 they were never used, so remove them instead of repairing them.
19703 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19704 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19705 Previously, this ceilinged at INT_MAX, but that doesn't work on
19707 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19709 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19710 (allocate_vectorlike): Check for ptrdiff_t overflow.
19711 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19712 when a (possibly-narrower) signed value would do just as well.
19713 We prefer using signed arithmetic, to avoid comparison confusion.
19715 * alloc.c: Catch some string size overflows that we were missing.
19716 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19717 for convenience in STRING_BYTES_MAX.
19718 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19719 The definition here is exact; the one in lisp.h was approximate.
19720 (allocate_string_data): Check for string overflow. This catches
19721 some instances we weren't catching before. Also, it catches
19722 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19723 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19724 and ptrdiff_t and EMACS_INT are both 64 bits.
19726 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19727 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19728 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19730 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19732 * alloc.c (Fmake_string): Check for out-of-range init.
19734 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19736 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19738 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19740 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19741 xg_get_default_scrollbar_width.
19743 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19744 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19745 (style_changed_cb): Call update_theme_scrollbar_width and call

19747 all frames (Bug#8505).
19748 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19749 Call gtk_window_set_resizable if HAVE_GTK3.

19751 and height if HAVE_GTK3 (Bug#8505).
19752 (scroll_bar_width_for_theme): New variable.
19753 (update_theme_scrollbar_width): New function.
19754 (xg_get_default_scrollbar_width): Move code to
19755 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19756 (xg_initialize): Call update_theme_scrollbar_width.
19758 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19760 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19762 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19764 * frame.c (make_frame): Call other_buffer_safely instead of
19767 * window.c (temp_output_buffer_show): Call display_buffer with
19768 second argument Vtemp_buffer_show_specifiers and reset latter
19769 immediately after the call.
19770 (Vtemp_buffer_show_specifiers): New variable.
19771 (auto_window_vscroll_p, next_screen_context_lines)
19772 (Vscroll_preserve_screen_position): Remove leading asterisks from

19817 * window.c (delete_deletable_window): Re-add.
19818 (Fset_window_configuration): Rewrite to handle dead buffers and
19819 consequently deletable windows.
19820 (window_tree, Fwindow_tree): Remove. Supply functionality in
19822 (compare_window_configurations): Simplify code.

19955 Remove static from declaration of Qdelete_window, it's
19956 temporarily needed by Fbury_buffer.
19957 (replace_window): Don't assign orig_top_line and
19959 (Fdelete_window, delete_window): Remove. Window deletion is

19961 (window_loop): Remove DELETE_OTHER_WINDOWS case.
19962 Replace Fdelete_window calls with calls to Qdelete_window.
19963 (Fdelete_other_windows): Remove. Deleting other windows is

20371 runs afoul of improving memory_full behavior. (Bug#8761)
20372 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20373 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,

20375 (Fgnutls_boot): No need to check for memory allocation failure,
20376 since xmalloc does that for us.

20407 Check for integer overflow with large hash tables.
20408 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20409 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20410 (SXHASH_REDUCE): New macro.

20414 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20415 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20416 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20417 Rewrite to use FIXNUM_BITS, as this simplifies things.
20418 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20419 Adjust signatures to match updated version of code.
20420 (consing_since_gc): Now EMACS_INT, since a single hash table can
20421 use more than INT_MAX bytes.
20423 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20425 Make it possible to build with GCC-4.6+ -O2 -flto.
20427 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20429 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20431 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20432 Call minibuffer-inactive-mode.
20434 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20436 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20437 Update dependencies.
20439 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20441 * data.c (init_data): Remove code for UTS, this system is not
20444 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20446 Don't force ./temacs to start in terminal mode.
20448 * frame.c (make_initial_frame): Initialize faces in all cases, not
20449 only when CANNOT_DUMP is defined.
20450 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20452 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20454 * dispnew.c (add_window_display_history): Use const for the string
20455 pointer. Remove declaration, not needed.
20457 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20459 Use 'inline', not 'INLINE'.
20460 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20461 * alloc.c, fontset.c (INLINE): Remove.
20462 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20463 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20464 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20465 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20466 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20468 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20470 Make it possible to run ./temacs.
20472 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20473 syms_of_callproc does the same thing. Remove test for
20474 "initialized", do it in the caller.
20475 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20477 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20479 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20480 (read_minibuf): Use get_minibuffer.
20481 (syms_of_minibuf): Use DEFSYM.
20482 (Qmetadata): New var.
20483 * data.c (Qbuffer): Don't make it static.
20484 (syms_of_data): Use DEFSYM.
20486 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20488 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20489 (CCL_CODE_MIN): New macro.
20491 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20493 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20495 * eval.c (Qdebug): Now static.
20496 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20497 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20498 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20500 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20502 * image.c: Various fixes to ImageMagick code comments.
20503 (Fimagemagick_types): Doc fix.
20505 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20507 Minor fixes prompted by GCC 4.6.0 warnings.
20509 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20511 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20512 (x_clipboard_manager_save_all): Move extern decl to ...
20513 * xterm.h: ... here, so that it can be checked for consistency.
20515 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20517 * xselect.c (x_clipboard_manager_save_frame)
20518 (x_clipboard_manager_save_all): New functions.
20519 (Fx_clipboard_manager_save): Lisp function deleted.
20521 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20522 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20524 * xterm.h: Update prototype.
20526 2011-05-28 William Xu <william.xwl@gmail.com>
20528 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20529 exiting (Bug#8239).
20531 2011-05-28 Jim Meyering <meyering@redhat.com>
20533 Avoid a sign-extension bug in crypto_hash_function.
20534 * fns.c (to_uchar): Define.
20535 (crypto_hash_function): Use it to convert some newly-signed
20536 variables to unsigned, to avoid sign-extension bugs. For example,
20537 without this change, (md5 "truc") would evaluate to
20538 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20539 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20540 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20542 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20544 Integer overflow fixes.
20546 * dbusbind.c: Serial number integer overflow fixes.
20547 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20548 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20549 to hold a serial number that is too large for a fixnum.
20550 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20551 Check for serial numbers out of range. Decode any serial number
20552 that was so large that it became a float. (Bug#8722)
20554 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20555 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20556 Use XFASTINT rather than XUINT when numbers are nonnegative.
20557 (xd_append_arg, Fdbus_method_return_internal):
20558 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20559 arguments, check that Lisp number is nonnegative, rather than
20560 silently wrapping negative numbers around. (Bug#8722)
20561 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20564 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20566 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20568 ccl: Add integer overflow checks.
20569 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20570 (IN_INT_RANGE): New macros.
20571 (ccl_driver): Use them to check for integer overflow when
20572 decoding a CCL program. Many of the new checks are whether XINT (x)
20573 fits in int; it doesn't always, on 64-bit hosts. The new version
20574 doesn't catch all possible integer overflows, but it's an
20575 improvement. (Bug#8719)
20577 * alloc.c (make_event_array): Use XINT, not XUINT.
20578 There's no need for unsigned here.
20580 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20581 This follows up to the 2011-05-06 change that substituted uintptr_t
20582 for EMACS_INT. This case wasn't caught back then.
20584 Rework Fformat to avoid integer overflow issues.
20585 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20586 now (part of C89). Include <verify.h>.
20587 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20588 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20589 (Fformat): Avoid the prepass trying to compute sizes; it was only
20590 approximate and thus did not catch overflow reliably. Instead, walk
20591 through the format just once, formatting and computing sizes as we go,
20592 checking for integer overflow at every step, and allocating a larger
20593 buffer as needed. Keep track separately whether the format is
20594 multibyte. Keep only the most-recently calculated precision, rather
20595 than them all. Record whether each argument has been converted to
20596 string. Use EMACS_INT, not int, for byte and char and arg counts.
20597 Support field widths and precisions larger than INT_MAX. Avoid
20598 sprintf's undefined behavior with conversion specifications such as %#d
20599 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20600 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20601 formatting out-of-range floating point numbers with int
20602 formats. (Bug#8668)
20604 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20606 * data.c: Avoid integer truncation in expressions involving floats.
20607 * data.c: Include <intprops.h>.
20608 (arith_driver): When there's an integer overflow in an expression
20609 involving floating point, convert the integers to floating point
20610 so that the resulting value does not suffer from catastrophic
20611 integer truncation. For example, on a 64-bit host (* 4
20612 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20613 Do not rely on undefined behavior after integer overflow.
20615 merge count_size_as_multibyte, parse_str_to_multibyte
20616 * character.c, character.h (count_size_as_multibyte):
20617 Rename from parse_str_to_multibyte; all uses changed.
20618 Check for integer overflow.
20619 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20620 since it's now a duplicate of the other. This is more of
20621 a character than a buffer op, so better that it's in character.c.
20622 * fns.c, print.c: Adjust to above changes.
20624 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20626 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20628 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20630 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20631 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20632 (x_clipboard_manager_save): Now static.
20633 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20635 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20636 (crypto_hash_function): Now static.
20637 Fix pointer signedness problems. Avoid unnecessary initializations.
20639 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20641 * termhooks.h (Vselection_alist): Make it terminal-local.
20643 * terminal.c (create_terminal): Initialize it.
20645 * xselect.c: Support for clipboard managers.
20646 (Vselection_alist): Move to termhooks.h as terminal-local var.
20647 (LOCAL_SELECTION): New macro.
20648 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20649 (symbol_to_x_atom): Remove gratuitous arg.
20650 (x_handle_selection_request, lisp_data_to_selection_data)
20651 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20652 (x_own_selection, x_get_local_selection, x_convert_selection):
20653 New arg, specifying work frame. Use terminal-local Vselection_alist.
20654 (some_frame_on_display): Delete unused function.
20655 (Fx_own_selection_internal, Fx_get_selection_internal)
20656 (Fx_disown_selection_internal, Fx_selection_owner_p)
20657 (Fx_selection_exists_p): New optional frame arg.
20658 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20659 (x_handle_selection_clear): Don't treat other terminals with the
20660 same keyboard specially. Use the terminal-local Vselection_alist.
20661 (x_clear_frame_selections): Use Frun_hook_with_args.
20663 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20665 * xterm.h: Add support for those atoms.
20667 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20669 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20670 (converted_selections, conversion_fail_tag): New global variables.
20671 (x_selection_request_lisp_error): Free the above.
20672 (x_get_local_selection): Remove unnecessary code.
20673 (x_reply_selection_request): Args changed; handle arbitrary array
20674 of converted selections stored in converted_selections.
20675 Separate the XChangeProperty and SelectionNotify steps.
20676 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20677 (x_convert_selection): New function.
20678 (x_handle_selection_event): Simplify.
20679 (x_get_foreign_selection): Don't ignore incoming requests while
20680 waiting for an answer; this will fail when we implement
20681 SAVE_TARGETS, and seems unnecessary anyway.
20682 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20683 (Vx_sent_selection_functions): Doc fix.
20685 2011-05-26 Leo Liu <sdl.web@gmail.com>
20687 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20689 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20691 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20693 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20694 for fringe update if it has periodic bitmap.
20695 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20696 and fringe_bitmap_periodic_p.
20698 * fringe.c (get_fringe_bitmap_data): New function.
20699 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20700 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20701 row. Mark glyph row for fringe update if periodicity changed.
20703 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20704 for fringe update unless it has periodic bitmap.
20706 2011-05-25 Kenichi Handa <handa@m17n.org>
20708 * xdisp.c (get_next_display_element): Set correct it->face_id for
20709 a static composition.
20711 2011-05-24 Leo Liu <sdl.web@gmail.com>
20714 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20716 * fns.c (crypto_hash_function, Fsha1): New function.
20717 (Fmd5): Use crypto_hash_function.
20718 (syms_of_fns): Add Ssha1.
20720 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20722 * gnutls.c: Remove unused macros.
20723 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20724 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20725 Remove macros that are defined and never used.
20726 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20728 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20730 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20731 (Fx_get_selection_internal): Minor cleanup.
20732 (Fx_own_selection_internal): Rename arguments for consistency with
20735 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20737 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20739 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20741 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20743 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20745 * dispnew.c (scrolling_window): Don't exclude the case that the
20746 last enabled row in the desired matrix touches the bottom boundary.
20748 2011-05-21 Glenn Morris <rgm@gnu.org>
20750 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20751 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20752 and add some more files.
20754 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20756 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20757 report_file_error introduced by the change from 2011-05-07.
20759 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20761 * systime.h (Time): Define only if emacs is defined.
20762 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20763 where the include path doesn't have X11/X.h by default. See
20764 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20766 2011-05-20 Kenichi Handa <handa@m17n.org>
20768 * composite.c (find_automatic_composition): Fix previous change.
20770 2011-05-20 Glenn Morris <rgm@gnu.org>
20772 * lisp.mk: New file, split from Makefile.in.
20773 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20774 (shortlisp): Remove.
20775 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20777 2011-05-19 Glenn Morris <rgm@gnu.org>
20779 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20780 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20781 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20782 (lisp): Set the order to that of loadup.el.
20783 (shortlisp): Make it a copy of $lisp.
20784 (SOME_MACHINE_LISP): Remove.
20785 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20786 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20788 2011-05-18 Kenichi Handa <handa@m17n.org>
20790 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20791 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20792 (find_automatic_composition): Mostly rewrite for efficiency.
20794 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20796 * makefile.w32-in: Update dependencies.
20798 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20800 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20801 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20803 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20805 Fix some integer overflow issues, such as string length overflow.
20807 * insdel.c (count_size_as_multibyte): Check for string overflow.
20809 * character.c (lisp_string_width): Check for string overflow.
20810 Use EMACS_INT, not int, for string indexes and lengths; in
20811 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20812 the resulting string length overflows an EMACS_INT; instead,
20813 report a string overflow if no precision given. When checking for
20814 precision exhaustion, use a check that cannot possibly have
20815 integer overflow. (Bug#8675)
20816 * character.h (lisp_string_width): Adjust to new signature.
20818 * alloc.c (string_overflow): New function.
20819 (Fmake_string): Use it. This doesn't change behavior, but saves
20820 a few bytes and will simplify future changes.
20821 * character.c (string_escape_byte8): Likewise.
20822 * lisp.h (string_overflow): New decl.
20824 Fixups, following up to the user-interface timestamp change.
20825 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20826 for UI timestamps, instead of unsigned long.
20827 * msdos.c (mouse_get_pos): Likewise.
20828 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20829 * w32gui.h (Time): Define by including "systime.h" rather than by
20830 declaring it ourselves. (Bug#8664)
20832 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20833 * image.c (clear_image_cache): Likewise.
20835 * term.c (term_mouse_position): Don't assume time_t wraparound.
20837 Be more systematic about user-interface timestamps.
20838 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20839 and sometimes 'EMACS_UINT', to represent these timestamps.
20840 This change causes it to use 'Time' uniformly, as that's what X uses.
20841 This makes the code easier to follow, and makes it easier to catch
20842 integer overflow bugs such as Bug#8664.
20843 * frame.c (Fmouse_position, Fmouse_pixel_position):
20844 Use Time, not unsigned long, for user-interface timestamps.
20845 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20846 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20847 * keyboard.h (last_event_timestamp): Likewise.
20848 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20849 * menu.h (xmenu_show): Likewise.
20850 * term.c (term_mouse_position): Likewise.
20851 * termhooks.h (struct input_event.timestamp): Likewise.
20852 (struct terminal.mouse_position_hook): Likewise.
20853 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20854 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20855 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20856 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20857 what it was before.
20858 * menu.h, termhooks.h: Include "systime.h", for Time.
20860 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20861 Don't assume that the difference between two unsigned long values
20862 can fit into an integer. At this point, we know button_down_time
20863 <= event->timestamp, so the difference must be nonnegative, so
20864 there's no need to cast the result if double-click-time is
20865 nonnegative, as it should be; check that it's nonnegative, just in
20866 case. This bug is triggered when events are more than 2**31 ms
20867 apart (about 25 days). (Bug#8664)
20869 * xselect.c (last_event_timestamp): Remove duplicate decl.
20870 (x_own_selection): Remove needless cast to unsigned long.
20872 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20873 that always fit in int. Use a sentinel instead of a counter, to
20874 avoid a temp and to allay GCC's concerns about possible int overflow.
20875 * frame.h (struct frame): Use int for menu_bar_items_used
20876 instead of EMACS_INT, since it always fits in int.
20878 * menu.c (grow_menu_items): Check for int overflow.
20880 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20882 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20883 Before, the code was not consistent. These values cannot exceed
20884 2**31 - 1 so there's no need to make them unsigned.
20885 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20886 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20887 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20889 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20891 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20892 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20893 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20894 presumably because the widths might not match.
20896 * window.c (size_window): Avoid needless test at loop start.
20898 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20900 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20902 2011-05-12 Drew Adams <drew.adams@oracle.com>
20904 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20906 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20908 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20909 `width' to `bar_area_x' and `bar_area_width', respectively.
20910 (x_scroll_run): Take account of fringe background extension.
20912 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20913 Rename local vars `left' and `width' to `bar_area_x' and
20914 `bar_area_width', respectively.
20915 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20916 background extension.
20918 2011-05-10 Jim Meyering <meyering@redhat.com>
20920 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20922 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20924 * image.c (Finit_image_library): Return t for built-in image types,
20925 like pbm and xbm. (Bug#8640)
20927 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20929 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20931 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20933 * w32console.c (Fset_screen_color): Doc fix.
20934 (Fget_screen_color): New function.
20935 (syms_of_ntterm): Defsubr it.
20937 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20938 unlink the temporary file if Fcall_process didn't create it in the
20940 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20941 child process will be redirected to a file specified with `:file'.
20942 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20943 cue to call_process_cleanup not to close that handle.
20945 2011-05-07 Ben Key <bkey76@gmail.com>
20947 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20948 one of two shell specific rules, either bootstrap-temacs-CMD or
20949 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20950 to the previous implementation of the bootstrap-temacs rule.
20951 The bootstrap-temacs-CMD rule is similar to the previous
20952 implementation of the bootstrap-temacs rule except that it
20953 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20956 These changes, along with some changes to nt/configure.bat,
20957 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20958 earlier fix to add support for --cflags and --ldflags options
20959 that include quotes so that it works whether make uses cmd or
20962 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20964 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20965 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20967 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20968 a string. Handle both cases.
20969 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20970 (Fdbus_register_method): Use Qinvalid_function.
20972 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20974 * makefile.w32-in: Update dependencies.
20975 (LISP_H): Add inttypes.h and stdin.h.
20976 (PROCESS_H): Add unistd.h.
20978 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20980 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20981 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20983 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20985 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20987 * term.c (vfatal): Remove stray call to va_end.
20988 It's not needed and the C Standard doesn't allow it here anyway.
20990 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20991 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20993 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20996 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20998 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
21000 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
21002 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
21004 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
21006 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
21007 * charset.c (Fdefine_charset_internal): Don't initialize
21008 charset.code_space[15]. The value was garbage, on hosts with
21009 32-bit int (Bug#8600).
21011 * lread.c (read_integer): Be more consistent with string-to-number.
21012 Use string_to_number to do the actual conversion; this avoids
21013 rounding errors and fixes some other screwups. Without this fix,
21014 for example, #x1fffffffffffffff was misread as -2305843009213693952.
21015 (digit_to_number): Move earlier, for benefit of read_integer.
21016 Return -1 if the digit is out of range for the base, -2 if it is
21017 not a digit in any supported base. (Bug#8602)
21019 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
21021 * dispnew.c (scrolling_window): Return 1 if we scrolled,
21022 to match comment at start of function. This also removes a
21023 GCC warning about overflow in a 32+64-bit port.
21025 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
21027 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
21028 Reported by Stefan Monnier in
21029 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
21030 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21031 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
21033 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
21034 (EMACS_UINTPTR): Likewise, with uintptr_t.
21036 * lisp.h: Prefer 64-bit EMACS_INT if available.
21037 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
21038 on 32-bit hosts that have 64-bit int, so that they can access
21040 However, temporarily disable this change unless the temporary
21041 symbol WIDE_EMACS_INT is defined.
21043 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
21045 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
21046 This removes an assumption that EMACS_INT and long are the same
21047 width as pointers. The assumption is true for Emacs porting targets
21048 now, but we want to make other targets possible.
21049 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
21050 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
21051 In the rest of the code, change types of integers that hold casted
21052 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
21053 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
21054 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
21055 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
21056 No need to cast type when ORing.
21057 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
21058 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
21059 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
21060 assume EMACS_INT is the same width as char *.
21061 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
21062 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
21063 Remove no-longer-needed casts.
21064 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
21065 (xg_tool_bar_help_callback, xg_make_tool_item):
21066 Use EMACS_INTPTR to hold an integer
21067 that will be cast to void *; this can avoid a GCC warning
21068 if EMACS_INT is not the same width as void *.
21069 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
21070 * xdisp.c (display_echo_area_1, resize_mini_window_1):
21071 (current_message_1, set_message_1):
21072 Use a local to convert to proper width without a cast.
21073 * xmenu.c (dialog_selection_callback): Likewise.
21075 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
21076 Also, don't assume VALBITS / RAND_BITS is less than 5,
21077 and don't rely on undefined behavior when shifting a 1 left into
21079 * lisp.h (get_random): Change signature to match.
21081 * lread.c (hash_string): Use size_t, not int, for hash computation.
21082 Normally we prefer signed values; but hashing is special, because
21083 it's better to use unsigned division on hash table sizes so that
21084 the remainder is nonnegative. Also, size_t is the natural width
21085 for hashing into memory. The previous code used 'int', which doesn't
21086 retain enough info to hash well into very large tables.
21087 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21089 * dbusbind.c: Don't possibly lose pointer info when converting.
21090 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21091 Use XPNTR rather than XHASH, so that the high-order bits of
21092 the pointer aren't lost when converting through void *.
21094 * eval.c (Fautoload): Don't double-shift a pointer.
21096 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21098 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21100 * gnutls.c (DEF_GNUTLS_FN):
21101 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21103 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21105 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21108 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21110 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21111 New version that can reserve upto 2GB of heap space.
21113 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21115 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21117 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21119 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21120 `gnutls_certificate_set_x509_key_file'.
21122 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21124 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21125 Update dependencies.
21127 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21129 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21130 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21131 Remove unused parameter `fildes'.
21132 * process.c (read_process_output, send_process): Don't pass it.
21134 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21136 Fix previous change: the library cache is defined in w32.c.
21137 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21138 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21140 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21142 Implement dynamic loading of GnuTLS on Windows.
21144 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21145 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21146 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21149 * gnutls.c (Qgnutls_dll): Define.
21150 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21151 (gnutls_*): Declare function pointers.
21152 (init_gnutls_functions): New function to initialize function pointers.
21153 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
21154 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21155 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21156 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21157 (emacs_gnutls_write, emacs_gnutls_read)
21158 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21159 (Fgnutls_available_p): New function.
21160 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21161 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21162 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21164 * image.c: Include w32.h.
21165 (Vimage_type_cache): Delete.
21166 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
21167 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
21168 (w32_delayed_load): Move to w32.c.
21170 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21172 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21173 (w32_delayed_load): Move from image.c. When loading a library, record
21174 its filename in the :loaded-from property of the library id.
21175 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21176 Initialize and staticpro them.
21177 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21179 * process.c: Include lisp.h before w32.h, not after.
21180 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21181 instead of gnutls_record_check_pending.
21183 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21185 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21187 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21188 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21191 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21193 * xterm.c (x_set_frame_alpha): Do not set property on anything
21194 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21196 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21198 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21200 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21202 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
21203 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

21209 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
21210 (Qgnutls_bootprop_callbacks_verify): Make static.
21212 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
21214 * callproc.c: Indentation fixup.
21216 * sysdep.c (wait_for_termination_1): Make static.
21217 (wait_for_termination, interruptible_wait_for_termination):
21218 Move after wait_for_termination_1.
21220 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21222 * sysdep.c (interruptible_wait_for_termination): New function
21223 which is like wait_for_termination, but allows keyboard
21226 * callproc.c (Fcall_process): Add (:file "file") as an option for
21228 (Fcall_process_region): Ditto.
21230 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21232 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21233 rather than `XVECTOR (FOO)->size'.
21235 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21236 inttypes.h, as a gnulib replacement is used if it not available in
21239 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21241 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21242 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21243 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21245 * coding.c (coding_alloc_by_realloc): Error out if destination
21246 will grow beyond MOST_POSITIVE_FIXNUM.
21247 (decode_coding_emacs_mule): Abort if there isn't enough place in
21248 charbuf for the composition carryover bytes. Reserve an extra
21249 space for up to 2 characters produced in a loop.
21250 (decode_coding_iso_2022): Abort if there isn't enough place in
21251 charbuf for the composition carryover bytes.

21256 aborting when %lld or %lll format is passed.
21257 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21258 %llo or %llx format is passed. (Bug#8545)
21260 * window.c (window_scroll_line_based): Use a marker instead of
21261 simple variables to record original value of point. (Bug#7952)
21263 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21264 produced by %s or %c overflows available buffer space. (Bug#8545)
21266 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21268 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21269 (SIZE_MAX): Move defn after all includes, as they might #define it.
21271 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21273 * w32.c (init_environment): Warn about defaulting HOME to C:\.
21275 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

21278 (command_loop_1): Run `delayed-warnings-hook'
21279 if Vdelayed_warnings_list is non-nil.
21280 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21281 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21283 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21285 * doprnt.c (doprnt): Don't return value smaller than the buffer
21286 size if the message was truncated. (Bug#8545).
21288 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21290 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21291 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21293 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21295 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21297 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21299 * makefile.w32-in: Update dependencies.
21301 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21303 Improve `doprnt' and its usage. (Bug#8545)
21304 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21305 `format_end'. Remove support for %l as a conversion specifier.
21306 Don't use xrealloc. Improve diagnostics when the %l size modifier
21307 is used. Update the commentary.
21309 * eval.c (verror): Simplify calculation of size_t.
21311 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21314 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21316 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21319 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21321 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21322 This makes this file independent of the recent pseudovector change.
21324 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21326 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21328 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21329 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21330 Remove unused local.
21331 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21333 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21334 GCC 4.6.0 optimizes based on type-based alias analysis.
21335 For example, if b is of type struct buffer * and v of type struct
21336 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21337 != &v->size, and therefore "v->size = 1; b->size = 2; return
21338 v->size;" must therefore return 1. This assumption is incorrect
21339 for Emacs, since it type-puns struct Lisp_Vector * with many other
21340 types. To fix this problem, this patch adds a new type struct
21341 vectorlike_header that documents the constraints on layout of vectors
21342 and pseudovectors, and helps optimizing compilers not get fooled
21343 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21344 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21345 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21347 (XSETPVECTYPE): Rewrite in terms of new macro.
21348 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21349 This is a bit clearer, and further avoids the possibility of
21350 undesirable aliasing.
21351 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21352 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21353 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21354 since Lisp_Subr is a special case (no "next" field).
21355 (ASIZE): Now uses header.size rather than size.
21356 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21357 to avoid the hassle of writing XVECTOR (foo)->header.size.
21358 (struct vectorlike_header): New type.
21359 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21360 object, to help avoid aliasing.
21361 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21362 (SUBRP): Likewise, since Lisp_Subr is a special case.
21363 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21364 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21365 (struct Lisp_Hash_Table): Combine first two members into a single
21366 struct vectorlike_header member. All uses of "size" and "next" members
21367 changed to be "header.size" and "header.next".
21368 * buffer.h (struct buffer): Likewise.
21369 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21370 * frame.h (struct frame): Likewise.
21371 * process.h (struct Lisp_Process): Likewise.
21372 * termhooks.h (struct terminal): Likewise.
21373 * window.c (struct save_window_data, struct saved_window): Likewise.
21374 * window.h (struct window): Likewise.
21375 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21376 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21377 * buffer.c (init_buffer_once): Likewise.
21378 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21380 * process.c (Fformat_network_address): Use local var for size,
21383 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21385 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21386 * data.c (atof): Remove decl; no longer used or needed.
21387 (digit_to_number): Move to lread.c.
21388 (Fstring_to_number): Use new string_to_number function, to be
21389 consistent with how the Lisp reader treats infinities and NaNs.
21390 Do not assume that floating-point numbers represent EMACS_INT
21391 without losing information; this is not true on most 64-bit hosts.
21392 Avoid double-rounding errors, by insisting on integers when
21393 parsing non-base-10 numbers, as the documentation specifies.
21394 * lisp.h (string_to_number): New decl, replacing ...
21395 (isfloat_string): Remove.
21396 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21397 (read1): Do not accept +. and -. as integers; this
21398 appears to have been a coding error. Similarly, do not accept
21399 strings like +-1e0 as floating point numbers. Do not report
21400 overflow for integer overflows unless the base is not 10 which
21401 means we have no simple and reliable way to continue.
21402 Break out the floating-point parsing into a new
21403 function string_to_number, so that Fstring_to_number parses
21404 floating point numbers consistently with the Lisp reader.
21405 (digit_to_number): Move here from data.c. Make it static inline.
21406 (E_CHAR, EXP_INT): Remove, replacing with ...
21407 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21408 (string_to_number): New function, replacing isfloat_string.
21409 This function checks for valid syntax and produces the resulting
21410 Lisp float number too. Rework it so that string-to-number
21411 no longer mishandles examples like "1.0e+". Use strtoumax,
21412 so that overflow for non-base-10 numbers is reported only when
21413 there's no portable and simple way to convert to floating point.
21415 * textprop.c (set_text_properties_1): Rewrite for clarity,
21416 and to avoid GCC warning about integer overflow.
21418 * intervals.h (struct interval): Use EMACS_INT for members
21419 where EMACS_UINT might cause problems. See
21420 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21421 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21422 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21424 (offset_intervals): Tell GCC not to worry about length overflow
21425 when negating a negative length.
21427 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21428 (overrun_check_free): Likewise.
21430 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21431 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21434 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21435 (gnutls_make_error): Rename local to avoid shadowing.
21436 (gnutls_emacs_global_deinit): ifdef out; not used.
21437 (Fgnutls_boot): Use const for pointer to readonly storage.
21438 Comment out unused local. Fix pointer signedness problems.
21440 * lread.c (openp): Don't stuff size_t into an 'int'.
21441 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21442 about possible signed overflow.
21444 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21445 (GDK_KEY_g): Don't define if already defined.
21446 (xg_prepare_tooltip): Avoid pointer signedness problem.
21447 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21449 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21450 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21452 * xfns.c (Fx_window_property): Simplify a bit,
21453 to make a bit faster and to avoid GCC 4.6.0 warning.
21454 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21456 * fns.c (internal_equal): Don't assume size_t fits in int.
21458 * alloc.c (compact_small_strings): Tighten assertion a little.
21460 Replace pEd with more-general pI, and fix some printf arg casts.
21461 * lisp.h (pI): New macro, generalizing old pEd macro to other
21462 conversion specifiers. For example, use "...%"pI"d..." rather
21463 than "...%"pEd"...".
21464 (pEd): Remove. All uses replaced with similar uses of pI.
21465 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21466 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21467 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21468 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21469 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21470 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21471 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21473 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21474 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21475 * print.c (safe_debug_print, print_object): Likewise.
21476 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21478 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21479 avoiding the 0 flag, which is not portable.
21480 * process.c (Fmake_network_process): Use pI to avoid cast.
21481 * region-cache.c (pp_cache): Likewise.
21482 * xdisp.c (decode_mode_spec): Likewise.
21483 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21484 behavior on 64-bit hosts with printf arg.
21485 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21486 (x_stop_queuing_selection_requests): Likewise.
21487 (x_get_window_property): Don't truncate byte count to an 'int'
21490 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21491 here, since it parses constructs like leading '-' and spaces,
21492 which are not wanted; and it overflows with large numbers.
21493 Instead, simply match F[0-9]+, which is what is wanted anyway.
21495 * alloc.c: Remove unportable assumptions about struct layout.
21496 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21497 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21498 (allocate_vectorlike, make_pure_vector): Use the new macros,
21499 plus offsetof, to remove unportable assumptions about struct layout.
21500 These assumptions hold on all porting targets that I know of, but
21501 they are not guaranteed, they're easy to remove, and removing them
21502 makes further changes easier.
21504 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21505 This doesn't fix a bug but makes the code clearer.
21506 (string_overrun_cookie): Now const. Use initializers that
21507 don't formally overflow signed char, to avoid warnings.
21508 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21509 can cause Emacs to crash when string overrun checking is enabled.
21510 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21511 multiple of sizeof (EMACS_INT); it need not be, if
21512 alignof(EMACS_INT) < sizeof (EMACS_INT).
21513 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21515 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21519 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
21521 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
21522 supposed to be handshaking. (Bug#8556)
21523 Reported by Paul Eggert <eggert@cs.ucla.edu>.
21525 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
21527 * lisp.h (Qdebug): List symbol.
21528 * eval.c (Qdebug): Restore global linkage.

21530 (handle_user_signal): Break into debugger when debug-on-event
21531 matches the current signal symbol.
21533 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
21535 * alloc.c (check_sblock, check_string_bytes)
21536 (check_string_free_list): Convert to standard C.
21538 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21540 * w32.c (emacs_gnutls_push): Fix typo.
21542 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21544 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21545 "cast to pointer from integer of different size".
21547 Improve doprnt and its use in verror. (Bug#8545)
21548 * doprnt.c (doprnt): Document the set of format control sequences
21549 supported by the function. Use SAFE_ALLOCA instead of always
21552 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21553 is one byte too soon. Don't use xrealloc; instead xfree and
21556 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21558 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21561 * gnutls.c: Renamed global_initialized to
21562 gnutls_global_initialized. Added internals for the
21563 :verify-hostname-error, :verify-error, and :verify-flags
21564 parameters of `gnutls-boot' and documented those parameters in the
21565 docstring. Start callback support.
21566 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21567 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21568 on error. Return error code.
21569 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
21570 (emacs_gnutls_read): Likewise.
21571 (Fgnutls_boot): Return handshake error code.
21572 (emacs_gnutls_handle_error): New function.
21573 (wsaerror_to_errno): Likewise.

21584 buffered some data internally if no FDs are set for TLS
21587 * makefile.w32-in (OBJ2): Add gnutls.$(O).

21635 <char-direction-table>: Deleted.
21637 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21639 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
21640 * doprnt.c: Include limits.h.
21641 (SIZE_MAX): New macro.
21642 (doprnt): Return a size_t value. 2nd arg is now size_t.
21643 Many local variables are now size_t instead of int or unsigned.
21644 Improve overflow protection. Support `l' modifier for integer
21645 conversions. Support %l conversion. Don't assume an EMACS_INT
21646 argument for integer conversions and for %c.
21648 * lisp.h (doprnt): Restore prototype.
21650 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
21651 $(SRC)/character.h.
21653 * Makefile.in (base_obj): Add back doprnt.o.
21655 * deps.mk (doprnt.o): Add back prerequisites.
21656 (callint.o): Depend on character.h.
21658 * eval.c (internal_lisp_condition_case): Include the handler
21659 representation in the error message.
21660 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
21661 when breaking from the loop.
21663 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
21665 * callint.c (Fcall_interactively): When displaying error message
21666 about invalid control letter, pass the character's codepoint, not
21667 a pointer to its multibyte form. Improve display of the character
21668 in octal and display also its hex code.
21670 * character.c (char_string): Use %x to display the (unsigned)
21671 codepoint of an invalid character, to avoid displaying a bogus
21674 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21675 `error', not SYMBOL_NAME itself.
21677 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
21678 character arguments to `error'.
21680 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21681 to `error' in error message about FINAL_CHAR argument. Make sure
21682 FINAL_CHAR is a character, and use %c when it is passed as
21683 argument to `error'.

21747 Define only if needed.
21749 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
21750 by pacifying GCC about it. Maybe it's time to retire it?
21751 * xfaces.c (USG, __TIMEVAL__): Likewise.
21753 * dispextern.h (struct redisplay_interface): Rename param
21754 to avoid shadowing.

21802 compatible char. Avoid the old compiler warnings about
21803 out-of-range initializers by using, for example, '\xab' rather
21806 * xgselect.c (xgselect_initialize): Check vs interface
21807 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

21872 * nsfont.m: Fixed bugs in ns_get_family and
21873 ns_descriptor_to_entity that were caused by using free to
21874 deallocate memory blocks that were allocated by xmalloc (via
21875 xstrdup). This caused Emacs to crash when compiled with
21876 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21877 --enable-checking=xmallocoverrun). xfree is now used to
21878 deallocate these memory blocks.

21892 (emacs_read, emacs_write): Remove check for negative size, as the
21893 Emacs source code has been audited now.
21894 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
21895 (emacs_read, emacs_write): Use it.
21896 * process.c (send_process): Adjust to the new signatures of
21897 emacs_write and emacs_gnutls_write. Do not attempt to store
21898 a byte offset into an 'int'; it might overflow.
21899 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

22233 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
22234 * dispextern.h (bidi_dump_cached_states): Remove, since it's
22235 exported only to the debugger.
22237 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
22238 * atimer.h (run_all_atimers): Remove; not exported.
22240 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
22241 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
22242 was inaccessible from Lisp.
22243 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
22244 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
22246 alloc.c: Import and export fewer symbols, and remove unused items.
22247 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
22249 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
22250 it's not optimized away by whole-program optimization.

22263 (mark_backtrace): Define only if BYTE_MARK_STACK.
22264 * xdisp.c (message_enable_multibyte): Now static.
22266 Declare Lisp_Object Q* variables to be 'static' if not exported.
22267 This makes it easier for human readers (and static analyzers)
22268 to see whether these variables are used from other modules.
22269 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

22280 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
22282 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22284 Make Emacs functions such as Fatom 'static' by default.
22285 This makes it easier for human readers (and static analyzers)
22286 to see whether these functions can be called from other modules.
22287 DEFUN now defines a static function. To make the function external
22288 so that it can be used in other C modules, use the new macro DEFUE.

22294 Remove decls, since these functions are now static.
22295 (Funintern, Fget_internal_run_time): New decls, since these functions
22296 were already external.

22309 decls for now-static functions.
22310 * buffer.h (Fdelete_overlay): Remove decl.

22346 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22348 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22349 when at ZV. (Bug#8487)
22351 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>

22359 * xsettings.c (read_and_apply_settings): Likewise.
22361 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22362 (overrun_check_free): Protoize.
22364 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22366 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22367 since callers should never pass a negative size.
22368 Change the signature to match that of plain 'read' and 'write'; see
22369 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22370 * lisp.h: Update prototypes of emacs_write and emacs_read.
22372 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22374 * xdisp.c (redisplay_window): Don't try to determine the character
22375 position of the scroll margin if the window start point w->startp
22376 is outside the buffer's accessible region. (Bug#8468)
22378 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22380 Fix write-region and its subroutines for buffers > 2GB.
22381 * fileio.c (a_write, e_write): Modify declaration of arguments and
22382 local variables to support buffers larger than 2GB.
22383 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22385 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22386 argument, local variables, and return value.
22388 * lisp.h: Update prototypes of emacs_write and emacs_read.
22390 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22392 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22394 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22396 Fix more problems found by GCC 4.6.0's static checks.
22398 * xdisp.c (vmessage): Use a better test for character truncation.
22400 * charset.c (load_charset_map): <, not <=, for optimization,
22401 and to avoid potential problems with integer overflow.
22402 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22403 * casetab.c (set_identity, shuffle): Likewise.
22404 * editfns.c (Fformat): Likewise.
22405 * syntax.c (skip_chars): Likewise.
22407 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22408 This also lets GCC 4.6.0 generate slightly better loop code.
22410 * callint.c (Fcall_interactively): <, not <=, for optimization.
22411 (Fcall_interactively): Count the number of arguments produced,
22412 not the number of arguments given. This is simpler and lets GCC
22413 4.6.0 generate slightly better code.
22415 * ftfont.c: Distingish more carefully between FcChar8 and char.
22416 The previous code passed unsigned char * to a functions like
22417 strlen and xstrcasecmp that expect char *, which does not
22418 conform to the C standard.
22419 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22420 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22421 char * when the C standard requires it.
22423 * keyboard.c (read_char): Remove unused var.
22425 * eval.c: Port to Windows vsnprintf (Bug#8435).
22426 Include <limits.h>.
22427 (SIZE_MAX): Define if the headers do not.
22428 (verror): Do not give up if vsnprintf returns a negative count.
22429 Instead, grow the buffer. This ports to Windows vsnprintf, which
22430 does not conform to C99. Problem reported by Eli Zaretskii.
22431 Also, simplify the allocation scheme, by avoiding the need for
22432 calling realloc, and removing the ALLOCATED variable.
22434 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22436 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22437 But keep the doprint source code for now, as we might revamp it
22438 and use it again (Bug#8435).
22439 * lisp.h (doprnt): Remove.
22440 * Makefile.in (base_obj): Remove doprnt.o.
22441 * deps.mk (doprnt.o): Remove.
22443 error: Print 32- and 64-bit integers portably (Bug#8435).
22444 Without this change, on typical 64-bit hosts error ("...%d...", N)
22445 was used to print both 32- and 64-bit integers N, which relied on
22446 undefined behavior.
22447 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22448 * lisp.h (error, verror): Mark as printf-like functions.
22449 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22450 Report overflow in size calculations when allocating printf buffer.
22451 Do not truncate output string at its first null byte.
22452 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22453 Truncate the output at a character boundary, since vsnprintf does not
22455 * charset.c (check_iso_charset_parameter): Convert internal
22456 character to string before calling 'error', since %c now has the
22458 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22459 overflow when computing char to be passed to 'error'. Do not
22460 pass Lisp_Object to 'error'; pass the integer instead.
22461 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22462 formatted with plain %d.
22464 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22466 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22468 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22470 * xterm.c (x_catch_errors): Remove duplicate declaration.
22472 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22474 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22476 2011-04-10 Jim Meyering <meyering@redhat.com>
22478 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22479 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22480 return ssize_t not "int", and use size_t as the buffer length.
22481 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22482 * gnutls.h: Update declarations.
22483 * process.c (read_process_output): Use ssize_t, to match.
22484 (send_process): Likewise.
22486 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22488 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22490 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22492 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22493 Use unsigned char, to match FcChar8 type definition.
22495 * xterm.c (handle_one_xevent):
22496 * xmenu.c (create_and_show_popup_menu):
22497 * xselect.c (x_decline_selection_request)
22498 (x_reply_selection_request): Avoid type-punned deref of X events.
22500 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22502 Fix some uses of `int' instead of EMACS_INT.
22503 * search.c (string_match_1, fast_string_match)
22504 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22505 (scan_buffer, find_next_newline_no_quit)
22506 (find_before_next_newline, search_command, Freplace_match)
22507 (Fmatch_data): Make some `int' variables be EMACS_INT.
22509 * xdisp.c (display_count_lines): 3rd argument and return value now
22510 EMACS_INT. All callers changed.
22511 (pint2hrstr): Last argument is now EMACS_INT.
22513 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22514 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22515 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

22529 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22530 (encode_invocation_designation): Last argument P_NCHARS is now
22532 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22533 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22535 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22538 * ccl.c (Fccl_execute_on_string): Declare some variables
22541 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22543 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22545 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22547 * process.c (Fformat_network_address): Doc fix.
22549 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22551 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22553 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22555 * keyboard.c (read_char): Call Lisp function help-form-show,
22556 instead of using internal_with_output_to_temp_buffer.
22557 (Qhelp_form_show): New var.
22558 (syms_of_keyboard): Use DEFSYM macro.
22560 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22567 (list_processes_1): Delete.
22569 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22571 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22573 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22575 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22577 Fix more problems found by GCC 4.6.0's static checks.

22599 This avoids several warnings with gcc -Wstrict-overflow.
22600 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22601 directly, rather than having caller test rule sign. This avoids
22602 some unnecessary tests.
22603 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22604 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22605 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22607 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22608 (xfont_open): Avoid unnecessary tests.
22610 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22612 * composite.h, composite.c (composition_gstring_put_cache):
22613 Use EMACS_INT, not int, for length.
22615 * composite.h (COMPOSITION_DECODE_REFS): New macro,
22616 breaking out part of COMPOSITION_DECODE_RULE.
22617 (COMPOSITION_DECODE_RULE): Use it.
22618 * composite.c (get_composition_id): Remove unused local vars,
22619 by using the new macro.
22621 * textprop.c (set_text_properties_1): Change while to do-while,
22622 since the condition is always true at first.
22624 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22625 (interval_deletion_adjustment): Return unsigned value.
22628 * process.c (list_processes_1, create_pty, read_process_output):
22629 (exec_sentinel): Remove vars that were set but not used.
22630 (create_pty): Remove unnecessary "volatile"s.
22631 (Fnetwork_interface_info): Avoid possibility of int overflow.
22632 (read_process_output): Do adaptive read buffering even if carryover.
22633 (read_process_output): Simplify nbytes computation if buffered.

22641 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22642 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22644 * print.c (print_error_message): Avoid int overflow.
22646 * font.c (font_list_entities): Redo for clarity,
22647 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22649 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22650 (font_score): Avoid potential overflow in diff calculation.
22652 * fns.c (substring_both): Remove var that is set but not used.
22653 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22655 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22657 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22658 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22659 can always succeed if overflow has undefined behavior.
22661 * search.c (boyer_moore, wordify): Remove vars set but not used.
22662 (wordify): Omit three unnecessary tests.
22664 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22665 All callers changed. This avoids the need for an unused var.
22667 * casefiddle.c (casify_region): Remove var that is set but not used.
22669 * dired.c (file_name_completion): Remove var that is set but not used.
22671 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22673 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22674 (Finsert_file_contents): Remove unnecessary code checking fd.
22676 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22677 Check for integer overflow on size calculations.
22679 * buffer.c (Fprevious_overlay_change): Remove var that is set
22682 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22683 Remove vars that are set but not used.
22684 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22685 (timer_check_2): Mark vars as initialized.
22687 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22689 * image.c (lookup_image): Remove var that is set but not used.
22690 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22692 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22693 that are set but not used.
22695 * xfns.c (make_invisible_cursor): Don't return garbage
22696 if XCreateBitmapFromData fails (Bug#8410).
22698 * xselect.c (x_get_local_selection, x_handle_property_notify):
22699 Remove vars that are set but not used.
22701 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22702 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22704 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22705 Remove var that is set but not used.
22706 (scroll_bar_windows_size): Now size_t, not int.
22707 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22708 Check for overflow.
22710 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22711 (map_tty_color) [!defined MSDOS]: Likewise.
22713 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22715 * coding.c: Remove vars that are set but not used.
22716 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22717 All callers changed.
22718 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22719 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22720 (decode_coding_charset): Remove vars that are set but not used.
22722 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22723 that is set but not used.
22725 * print.c (print_object): Remove var that is set but not used.
22727 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22728 The gnulib version avoids calling malloc in the usual case,
22729 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22730 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22731 * filelock.c (current_lock_owner): Likewise.
22732 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22733 * sysdep.c: Include allocator.h, careadlinkat.h.
22734 (emacs_no_realloc_allocator): New static constant.
22735 (emacs_readlink): New function.
22736 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22737 ../lib/careadlinkat.h.
22739 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22741 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22742 first non-nil return value).
22744 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
22746 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22747 if not defined (Bug#8403).
22749 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22751 * xdisp.c (display_count_lines): Remove parameter `start',
22752 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22753 (get_char_face_and_encoding): Remove parameter `multibyte_p',
22754 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22756 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22757 and thereabouts. All callers changed.
22758 (get_per_char_metric): Remove parameter `f', unused since
22759 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22761 2011-04-02 Jim Meyering <meyering@redhat.com>
22763 do not dereference NULL upon failed strdup
22764 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22765 (ns_get_family): Likewise.
22767 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22769 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22771 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22773 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22776 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22778 Add lexical binding.
22780 * window.c (Ftemp_output_buffer_show): New fun.
22781 (Fsave_window_excursion):
22782 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
22784 * lread.c (lisp_file_lexically_bound_p): New function.
22785 (Fload): Bind Qlexical_binding.
22786 (readevalloop): Remove `evalfun' arg.
22787 Bind Qinternal_interpreter_environment.
22788 (Feval_buffer): Bind Qlexical_binding.
22789 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22791 (syms_of_lread): Declare `lexical-binding'.
22793 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22795 * keyboard.c (eval_dyn): New fun.
22796 (menu_item_eval_property): Use it.
22798 * image.c (parse_image_spec): Use Ffunctionp.
22800 * fns.c (concat, mapcar1): Accept byte-code-functions.
22802 * eval.c (Fsetq): Handle lexical vars.
22803 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22804 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22805 (FletX, Flet): Obey lexical binding.
22806 (Fcommandp): Handle closures.
22807 (Feval): New `lexical' arg.
22808 (eval_sub): New function extracted from Feval. Use it almost
22809 everywhere where Feval was used. Look up vars in lexical env.
22811 (Ffunctionp): Move from subr.el.
22812 (Ffuncall): Handle closures.
22813 (apply_lambda): Remove `eval_flags'.
22814 (funcall_lambda): Handle closures and new byte-code-functions.
22815 (Fspecial_variable_p): New function.
22816 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22817 but without exporting it to Lisp.
22819 * doc.c (Fdocumentation, store_function_docstring):
22820 * data.c (Finteractive_form): Handle closures.
22822 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22825 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22827 (exec_byte_code): New function extracted from Fbyte_code to handle new
22828 calling convention for byte-code-functions. Add new byte-codes.
22830 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22832 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22834 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22836 * xdisp.c (redisplay_internal): Fix prototype.
22838 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22840 * xdisp.c (SCROLL_LIMIT): New macro.
22841 (try_scrolling): Use it when setting scroll_limit.
22842 Limit scrolling to 100 screen lines.
22843 (redisplay_window): Even when falling back on "recentering",
22844 position point in the window according to scroll-conservatively,
22845 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22847 (try_scrolling): When point is above the window, allow searching
22848 as far as scroll_max, or one screenful, to compute vertical
22849 distance from PT to the scroll margin position. This prevents
22850 try_scrolling from unnecessarily failing when
22851 scroll-conservatively is set to a value slightly larger than the
22852 window height. Clean up the case of PT below the margin at bottom
22853 of window: scroll_max can no longer be INT_MAX. When aggressive
22854 scrolling is in use, don't let point enter the opposite scroll
22855 margin as result of the scroll.
22856 (syms_of_xdisp) <scroll-conservatively>: Document the
22857 threshold of 100 lines for never-recentering scrolling.
22859 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22861 * dispextern.h (move_it_by_lines):
22862 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22863 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22864 (message_log_check_duplicate): Remove parameters `prev_bol' and
22865 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22866 (redisplay_internal): Remove parameter `preserve_echo_area',
22867 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22869 * indent.c (Fvertical_motion):
22870 * window.c (window_scroll_pixel_based, Frecenter):
22871 Don't pass `need_y_p' to `move_it_by_lines'.
22873 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22875 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22876 steal a few bits to be more compact.
22877 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22878 Remove unneeded casts.
22880 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22882 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22884 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22885 binding" message (bug#7967).
22887 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22889 Fix more problems found by GCC 4.6.0's static checks.
22891 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22892 Remove unused local var.
22894 * editfns.c (Fmessage_box): Remove unused local var.
22896 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22897 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22898 Omit unused local vars.
22899 * window.c (shrink_windows): Omit unused local var.
22900 * menu.c (digest_single_submenu): Omit unused local var.
22901 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22902 Omit unused local var.
22904 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22905 Don't assume string length fits in int.
22906 (keyremap_step, read_key_sequence): Use size_t for sizes.
22907 (read_key_sequence): Don't check last_real_key_start redundantly.
22909 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22910 instead of alloca (Bug#8344).
22912 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22913 (Fbacktrace_frame): Don't assume nframes fits in int.
22915 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22917 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22920 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22922 * cm.c (calccost): Turn while-do into do-while, for clarity.
22924 * keyboard.c (syms_of_keyboard): Use the same style as later
22925 in this function when indexing through an array. This also
22926 works around GCC bug 48267.
22928 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22930 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22932 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22933 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22935 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22936 This avoids undefined behavior on integer overflow, and is a bit
22937 more convenient anyway since it is compared to a size_t variable.
22939 Variadic C functions now count arguments with size_t, not int.
22940 This avoids an unnecessary limitation on 64-bit machines, which
22941 caused (substring ...) to crash on large vectors (Bug#8344).
22942 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22943 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

22951 * fns.c (concat): Likewise.
22952 * frame.c (x_set_frame_parameters): Likewise.
22953 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22954 0 if not found, not -1. All callers changed.
22956 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22957 (stack_copy_size): Now size_t, not int.
22958 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22960 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22962 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22963 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22964 All callers changed.
22966 * lisp.h (multibyte_char_to_unibyte):
22967 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22968 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22979 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22980 don't set the hook to nil, but remove the offending function instead.
22981 (Qcommand_hook_internal): Remove, unused.
22982 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22983 Vcommand_hook_internal.
22985 * eval.c (enum run_hooks_condition): Remove.
22986 (funcall_nil, funcall_not): New functions.
22987 (run_hook_with_args): Call each function through a `funcall' argument.

23001 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
23002 All callers changed.
23004 * w32.c (_wsa_errlist): Use braces for struct initializers.
23006 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
23007 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
23008 All callers changed.

23163 * buffer.c (Fkill_all_local_variables):
23164 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
23166 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23167 unconditionally since it does the check itself.
23169 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23171 Fix more problems found by GCC 4.5.2's static checks.
23173 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23174 the first time through the loop, since we know p0 < p1 then.
23175 This also avoids a gcc -Wstrict-overflow warning.
23177 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23178 leading to a memory leak, possible in functions like
23179 load_charset_map_from_file that can allocate an unbounded number
23180 of objects (Bug#8318).
23182 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23183 that could (at least in theory) be that large.
23185 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23186 This is less likely to overflow, and avoids undefined behavior if
23187 overflow does occur. All callers changed. Use strtoul to scan
23188 for the unsigned long integer.
23189 (pint2hrstr): Simplify and tune code slightly.
23190 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

23200 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23203 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23205 * process.c (Fmake_network_process): Use socklen_t, not int,
23206 where POSIX says socklen_t is required in portable programs.
23207 This fixes a porting bug on hosts like 64-bit HP-UX, where
23208 socklen_t is wider than int (Bug#8277).
23209 (Fmake_network_process, server_accept_connection):
23210 (wait_reading_process_output, read_process_output):
23213 * process.c: Rename or move locals to avoid shadowing.

23223 Make tparam.h and terminfo.c consistent.
23224 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23225 Include tparam.h instead, since it declares them.
23226 * cm.h (PC): Remove extern decl; tparam.h now does this.
23227 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23228 * terminfo.c: Include tparam.h, to check interfaces.
23229 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23230 (tparam): Adjust signature to match interface in tparam.h;
23231 this removes some undefined behavior. Check that outstring and len
23232 are zero, which they always are with Emacs.
23233 * tparam.h (PC, BC, UP): New extern decls.
23235 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23236 (xftfont_open): Rename locals to avoid shadowing.
23238 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

23250 * composite.c (composition_compute_stop_pos): Rename local to
23252 (composition_reseat_it): Remove unused locals.
23253 (find_automatic_composition, composition_adjust_point): Likewise.
23254 (composition_update_it): Mark var as initialized.
23255 (find_automatic_composition): Mark vars as initialized,
23256 with a FIXME (Bug#8290).

23260 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
23261 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
23262 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23263 to avoid shadowing.
23265 * textprop.c (property_change_between_p): Remove; unused.
23267 * intervals.c (interval_start_pos): Now static.
23269 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

23275 Fix pointer signedness.
23276 (alsa_choose_format): Remove unused local var.
23277 (wav_play): Initialize a variable to 0, to prevent undefined
23278 behavior (Bug#8278).
23280 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23282 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23284 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23285 clobbering (Bug#8298).
23286 * sysdep.c (sys_subshell): Likewise.
23287 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23289 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23290 This should get cleaned up, so that child_setup has the
23291 same signature on all platforms.
23293 * callproc.c (call_process_cleanup): Now static.
23294 (relocate_fd): Rename locals to avoid shadowing.
23296 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23298 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23299 not to be necessary, and produces flickering.
23301 2011-03-20 Glenn Morris <rgm@gnu.org>
23303 * config.in: Remove file.
23305 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
23307 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
23308 are now in src/globals.h.

23335 (sigchld_handler): Now static.
23337 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
23338 That way, the code declares only the vars that it needs.

23349 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
23350 Define only if needed.
23352 * unexelf.c (unexec): Name an expression,
23353 to avoid gcc -Wbad-function-cast warning.
23354 Use a different way to cause a compilation error if anyone uses
23355 n rather than nn, a way that does not involve shadowing.
23356 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23358 * deps.mk (unexalpha.o): Remove; unused.
23360 New file unexec.h, the (simple) interface for unexec (Bug#8267).

23431 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
23434 * lisp.h (eassert): Check that the argument compiles, even if
23435 ENABLE_CHECKING is not defined.
23437 * data.c (Findirect_variable): Name an expression, to avoid
23438 gcc -Wbad-function-cast warning.

23455 (Fmemory_limit): Cast sbrk's returned value to char *.

23481 (RETALLOC_IF): Define only if needed.
23482 (WORDCHAR_P): Likewise. This one is never needed, but is used
23483 only in a comment talking about a compiler bug, so put inside
23484 the #if 0 of that comment.

23514 gcpro1, gcpro2, etc.
23515 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23517 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second

23522 Rename locals to avoid shadowing.
23524 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).

23533 (downcase, upcase1): New static inline functions.
23534 (DOWNCASE, UPCASE1): Reimplement using these functions.
23535 This avoids undefined behavior in expressions like

23569 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

23576 * buffer.c (fix_overlays_before): Mark locals as initialized.
23577 (fix_start_end_in_overlays): Likewise. This function should be
23578 simplified by using pointers-to-pointers, but that's a different

23587 to suppress a gcc -Wclobbered warning that does not seem to be right.
23588 (MAXPATHLEN): Define only if needed.
23590 * process.c (serial_open, serial_configure): Move decls from here ...
23591 * systty.h: ... to here, so that they can be checked.

23937 a block, when the outer 'i' will do.

23950 -Wuninitialized does not deduce are never used uninitialized.
23951 (detect_coding_iso_2022): Initialize a local variable that might
23952 be used uninitialized. Leave a FIXME because it's not clear that
