3 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
4 The old approach, which fell back on DIR/.#FILE.0 through
5 DIR/.#FILE.9, had race conditions that could not be easily fixed.
6 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
7 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
8 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
9 because the locking mechanism was never reliable in that case).
10 This patch fixes this and other bugs discovered by a code
11 inspection that was prompted by
12 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
13 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
14 to avoid interoperability problems between the MS-Windows and
15 non-MS-Windows implementations. MS-Windows and non-MS-Windows
16 instances of Emacs now ignore each others' locks.
17 * filelock.c (defined_WINDOWSNT): New constant.
18 (MAKE_LOCK_NAME, fill_in_lock_file_name):
19 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
20 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
21 regular files on MS-Windows hosts.
22 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
23 Use SAFE_ALLOCA to avoid problems with long file names.
24 (MAX_LFINFO): Now a local constant, not a global macro.
25 (IS_LOCK_FILE): Remove.
26 (lock_file_1): Don't inspect errno if symlink call succeeds;
28 (lock_file): Document that this function can return if lock
30 (lock_file): Don't access freed storage.
32 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
34 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
36 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
38 * textprop.c: Use bool for booleans.
39 (validate_interval_range, Fadd_text_properties)
40 (Fremove_text_properties): Prefer bool to int when either works.
42 2013-03-02 Eli Zaretskii <eliz@gnu.org>
44 * textprop.c (Fadd_text_properties, Fremove_text_properties): If
45 the interval tree changes as a side effect of calling
46 modify_region, re-do processing starting from the call to
47 validate_interval_range. (Bug#13743)
49 2013-02-28 Eli Zaretskii <eliz@gnu.org>
51 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
54 2013-02-27 Eli Zaretskii <eliz@gnu.org>
56 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
57 _SH_DENYRW flag, instead of emacs_open, to deny any other process
58 access to the lock file until it is written and closed.
61 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
63 * callint.c (Qcall_interactively):
64 * macros.c (Qexecute_kbd_macro):
67 2013-02-26 Bastien Guerry <bzg@gnu.org>

71 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
73 Minor textprop integer cleanup.
74 * intervals.h, textprop.c (add_text_properties_from_list):
75 Return void, not int, since nobody uses the return value.
76 * textprop.c (validate_plist, add_properties, remove_properties)
77 (Fadd_text_properties):
78 Don't assume list length fits in int.
79 (interval_has_all_properties, interval_has_some_properties)
80 (interval_has_some_properties_list, add_properties, remove_properties)
81 (Fadd_text_properties, Fremove_text_properties)
82 (Fremove_list_of_text_properties, text_property_stickiness):
83 Use bool for booleans.
84 (Fadd_text_properties, Fremove_text_properties):
85 (Fremove_list_of_text_properties):
86 Reindent do-while as per GNU style.
88 2013-02-25 Eli Zaretskii <eliz@gnu.org>
90 Implement CLASH_DETECTION for MS-Windows.
92 * filelock.c [WINDOWSNT]: Include w32.h.
93 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
94 function of that name. Up-case the macro arguments.
95 (IS_LOCK_FILE): New macro.
96 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
97 (create_lock_file): New function, with body extracted from
99 [WINDOWSNT]: Implement lock files by writing a regular file with
100 the lock information as its contents.
101 (read_lock_data): New function, on Posix platforms just calls
103 [WINDOWSNT]: Read the lock info from the file.
104 (current_lock_owner): Call read_lock_data instead of calling
105 emacs_readlinkat directly.
106 (lock_file) [WINDOWSNT]: Run the file name through
109 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
110 just check if the process by that PID exists.
112 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
113 also present, as doing so will fail to error out if the file
116 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
118 * textprop.c (Fadd_text_properties, Fremove_text_properties)
119 (Fremove_list_of_text_properties): Skip all of the intervals in
120 the region between START and END that already have resp. don't
121 have the requested properties, not just the first one. Add
122 assertions that the loop afterwards always modifies the
123 properties. (Bug#13743)
125 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
127 * callint.c (Fcall_interactively): Use the right lexical environment

135 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
136 (START_FILES): Remove. All uses removed.
137 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
138 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
139 (buildobj.h): Use it.
140 ($(ALLOBJS)): Depend on globals.h.

143 * deps.mk (vm-limit.o):
144 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
145 Do not depend on mem-limits.h.
146 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
147 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
148 [__GNUC__ && !ORDINARY_LINK]: Remove.
149 * mem-limits.h, pre-crt0.c: Remove.
150 * unexaix.c, unexcoff.c: Don't include mem-limits.h.

152 (make_hdr): Use DATA_START instead of start_of_data.
153 * vm-limit.c: Move most of mem-limits.h's contents here.
154 (data_start): New decl. It's OK if this is approximate,
155 so simplify-away some unnecessary exactness.
156 (POINTER): Remove; all uses removed.
157 (data_space_start): Now char *, to avoid casts.
158 (exceeds_lisp_ptr): New function, replacing the old
159 EXCEEDS_LISP_PTR macro. All uses changed.
160 (check_memory_limits): Simplify and remove casts.
161 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

166 * xdisp.c (set_message): Only check for debug-on-message if STRING
167 is a string. (Bug#13797)
169 2013-02-24 Paul Eggert <eggert@cs.ucla.edu>
171 Fix regression introduced by July 10 filelock.c patch.
172 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
173 2012-07-10 patch to this file. Reported by Eli Zaretskii in
174 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
175 and diagnosed by Andreas Schwab in
176 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
178 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
180 Assume C89 or better.
181 * ralloc.c (SIZE, POINTER, NIL):
182 * vm-limit.c (POINTER):
183 Remove, replacing all uses with C89 equivalents. These old
184 symbols were present only for porting to pre-C89 platforms.
186 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
188 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
189 This avoids warning messages reported as part of Bug#13546.
191 2013-02-21 Ken Brown <kbrown@cornell.edu>
193 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.

200 (command_loop_1, read_char): Use it.
201 (Fcommand_execute): Remove, replace by an Elisp implementation.
202 (syms_of_keyboard): Adjust accordingly.
204 2013-02-19 Daniel Colascione <dancol@dancol.org>
206 * sheap.c (report_sheap_usage): Use message, not message1, so
207 that we don't try to create a buffer while we're in the middle
208 of dumping Emacs. Explain why.
210 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
211 * search.c (find_newline): Return byte position in bytepos.
213 (find_next_newline_no_quit, find_before_next_newline):
214 Add bytepos argument.

221 (get_visually_first_element, move_it_vertically_backward):
222 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
224 2013-02-19 Eli Zaretskii <eliz@gnu.org>
226 * w32proc.c (new_child): Avoid leaking handles if the subprocess

231 * xdisp.c (x_draw_vertical_border): For a window that is neither
232 the leftmost nor the rightmost, redraw both the left and the right
233 vertical borders. (Bug#13723)
235 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
237 * xml.c (init_libxml2_functions):

251 * frame.c (syms_of_frame): ... to here.
253 2013-02-16 Eli Zaretskii <eliz@gnu.org>
255 * w32.c (sys_chown): Remove unused function.
257 * w32term.c <input_signal_count>: Declare 'volatile'
258 unconditionally. (Bug#9066)
260 * w32.c (set_errno): Reset h_errno and don't set it to any other
261 value. Set errno instead.
262 (check_errno): Reset h_errno.
263 (sys_socket, socket_to_fd, sys_bind, sys_connect)
264 (sys_gethostname, sys_getservbyname, sys_getpeername)
265 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
266 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set

276 * keyboard.c (read_char): Fix calculation of auto-save time out
277 when auto-save-timeout is less than 4. (Bug#13720)
279 * w32proc.c (new_child): Free up to 2 slots of dead processes at a

288 value that is out of bounds.
289 (sys_accept): If fd is negative, do not set up the child_process
290 structure for reading.

302 (decode_mode_spec_coding, message3):
303 * xfaces.c (face_at_string_position): Use bool for booleans.
306 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
308 Fix AIX port (Bug#13650).
309 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
310 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
311 was #undeffed earlier, so it cannot be used as a macro here.
312 Use the constant and not the macro.
314 2013-02-15 Eli Zaretskii <eliz@gnu.org>
316 * w32proc.c (new_child): If no vacant slots are found in
317 child_procs[], make another pass looking for slots whose process
318 has exited or died. (Bug#13546)
320 * w32.c (sys_pipe): When failing due to file descriptors above
321 MAXDESC, set errno to EMFILE.
322 (_sys_read_ahead): Update cp->status when failing to read serial
323 communications input, so that the status doesn't stay at
324 STATUS_READ_IN_PROGRESS. (Bug#13546)
326 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
328 * gtkutil.c (tb_size_cb): New function.
329 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
331 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
333 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
336 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
338 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
340 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
342 * font.c (font_range): Add pos_byte argument. Adjust comment
344 * font.h (font_range): Adjust prototype.
345 * composite.c (autocmp_chars): Pass byte position to font_range.
346 Break long line. Remove useless prototype and format comment.
348 2013-02-13 Glenn Morris <rgm@gnu.org>
350 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
352 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
354 Improve AIX port some more (Bug#13650).
355 With this, it should be as good as it was in 23.3, though it's
356 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
357 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
358 * unexaix.c (start_of_text): Remove.
359 (_data, _text): Declare as char[], not int, as AIX manual suggests.
360 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
361 (orig_load_scnptr, orig_data_scnptr):
362 Now off_t, not long, since they are file offsets.
363 (make_hdr): Use _data, not start_of_data ().
364 This is the key part of the fix.
365 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
366 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
368 * pre-crt0.c (data_start): Initialize to 1.
369 This ports to compilers that optimize the external declaration
370 'int x = 0;' as if it were 'int x;' to shrink the executable.
372 Improve AIX port (Bug#13650).
373 This doesn't fix the bug, but it makes progress: Emacs builds now.
374 * unexaix.c: Include inttypes.h, stdarg.h.
375 (report_error, report_error_1): Mark as _Noreturn.
376 (report_error): Don't report the wrong errno.
377 (report_error_1): Now varargs. All callers changed.
378 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
379 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
380 (write_ptr): Use %p to print address rather than %lx and a cast
381 to unsigned long. Grow buffer a bit, to be safer.
383 2013-02-13 Eli Zaretskii <eliz@gnu.org>
385 * bidi.c (bidi_resolve_neutral): After finding the next
386 non-neutral character, accept NEUTRAL_ON type as well, because
387 directional control characters, such as LRE and RLE, have their
388 type converted to that by bidi_resolve_weak. This avoids aborts
389 when LRE/RLE follows a run of neutrals.
390 (bidi_move_to_visually_next): Assert that return value of
391 bidi_peek_at_next_level is non-negative. Negative values will
394 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
396 Minor getenv-related fixes.
397 * callproc.c (Fcall_process_region) [!DOS_NT]:
398 Avoid unnecessary duplicate call to getenv.
399 * callproc.c (init_callproc):
400 * dispnew.c (init_display):
401 * sysdep.c (sys_subshell):
402 Omit unnecessary cast of getenv or egetenv.
404 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
406 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
409 2013-02-12 Eli Zaretskii <eliz@gnu.org>
411 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
413 (display_line): Set w->region_showing to the value of
414 it->region_beg_charpos, not to -1. This fixes redisplay
415 optimization when cursor is moved up after M->. (Bug#13623)
417 (try_scrolling): Scroll text up more if point is too close to ZV
418 and inside the scroll margin. This makes sure point is moved
419 outside the scroll margin in these cases.
421 * window.h (struct window): region_showing can no longer be
424 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
426 Tune by using memchr and memrchr.
427 * doc.c (Fsnarf_documentation):
428 * fileio.c (Fsubstitute_in_file_name):
429 * search.c (find_newline, scan_newline):
430 * xdisp.c (pos_visible_p, display_count_lines):
431 Use memchr and memrchr rather than scanning byte-by-byte.
432 * search.c (find_newline): Rename from scan_buffer.
433 Omit first arg TARGET, as it's always '\n'. All callers changed.
435 Clean up read_key_sequence a tiny bit more.
436 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
437 (read_key_sequence): Remove unused locals.
439 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
441 Clean up read_key_sequence a bit; reread active keymaps after first event.
442 * keyboard.c (read_char, read_char_x_menu_prompt)
443 (read_char_minibuf_menu_prompt):
444 Replace nmaps+maps with a single `map' arg.
445 (follow_key): Operate on a single map.
446 (active_maps): New function.
447 (test_undefined): Also return true for nil bindings.
448 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
449 a single (composed) keymap. Remember `first_event' to choose the right
450 set of active keymaps. Recompute the set of keymaps after receiving
451 the first event. Remove GOBBLE_FIRST_EVENT.
452 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
453 * keyboard.h (read_char): Update declaration.
454 * lread.c (read_filtered_event): Adjust call to read_char.
456 2013-02-11 Eli Zaretskii <eliz@gnu.org>
458 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
459 Don't use the limitation on backwards movement when lines are truncated
460 in the window. (Bug#13675)
462 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
464 * marker.c (set_marker_internal): If desired position is passed
465 as a marker, avoid call to buf_charpos_to_bytepos.
466 * window.c (Fset_window_point): Omit redundant type checking.
467 (Fset_window_start): Likewise. Format comment.
468 (window_scroll_pixel_based): Use set_marker_restricted_both
469 with character and byte positions obtained from an iterator.
470 (Fset_window_configuration): Use set_marker_restricted_both.
471 * xdisp.c (message_dolog): Likewise.
473 2013-02-10 Eli Zaretskii <eliz@gnu.org>
475 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
476 When text lines are longer than window's screen lines, don't move back
477 too far. This speeds up some redisplay operations. (Bug#13675)
479 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
481 * syntax.c (scan_sexps_forward): Fix byte position calculation

486 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
489 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
491 Minor hashing refactoring.
492 * fns.c (SXHASH_REDUCE): Move to lisp.h.
493 (sxhash_float): Return EMACS_UINT, for consistency with the other
495 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
496 non-static inline function and therefore can't use static vars.
497 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
498 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
499 with the other hash functions.
501 2013-02-09 Eli Zaretskii <eliz@gnu.org>
503 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
504 XXXXXX part of the temporary file pattern is not downcased even
505 when w32-downcase-file-names is non-nil. (Bug#13661)
507 * xdisp.c (decode_mode_spec): Remove handling of %t.
509 * msdos.c (careadlinkatcwd): Remove.
511 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
513 * lread.c (skip_dyn_bytes): New function (bug#12598).

530 * alloc.c (Fvector, Fmake_byte_code):
531 * ccl.c (Fregister_ccl_program):
532 * charset.c (Fdefine_charset_internal, define_charset_internal):

546 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
548 * coding.c (Fdefine_coding_system_internal): Use AREF where
549 argument is known to be a vector.
550 * fns.c (Flocale_info): Likewise for ASET.
551 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
552 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
554 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
556 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
559 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.

569 (check_native_fs): New function.
570 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
571 (ns_term_init): Remove NEW_STYLE_FS.

589 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
591 * fileio.c (Qchoose_write_coding_system): Now static.
593 2013-02-04 Eli Zaretskii <eliz@gnu.org>
595 * xdisp.c (window_buffer_changed): region_showing can be negative,
596 which still means region is being displayed.
597 (redisplay_internal): Resurrect code that forced redisplay of the
598 whole window when showing region and the mark has changed.
599 Record the new mark position to allow redisplay optimizations.
600 (display_line): If it->region_beg_charpos is non-zero, set the

603 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
604 not bitfield of 1 bit.
606 2013-02-03 Daniel Colascione <dancol@dancol.org>
608 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
609 daemon mode works on cygw32 when Emacs is installed and not just
612 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
614 Avoid file time stamp bug on MS-Windows (Bug#13149).
615 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
616 as FAT32 doesn't update time stamps when truncating them.
617 Also, check that a file time stamp is not a multiple of 100 ns;
618 this should catch all instances of the problem on MS-Windows,
619 as its native file system resolution is 100 ns or worse, and
620 checking for a non-multiple of 100 ns should impose only a small
621 overhead on systems with ns resolution.
623 2013-02-02 Eli Zaretskii <eliz@gnu.org>
625 Avoid encoding file names on MS-Windows when they need to be run
626 through dostounix_filename.
627 * w32.c (normalize_filename): Accept an additional argument
628 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
629 downcase it even if w32-downcase-file-names is non-nil.
630 (dostounix_filename): Accept an additional argument MULTIBYTE and
631 pass it to normalize_filename.
632 (emacs_root_dir): Adjust.
634 * msdos.h (dostounix_filename): Adjust prototype.
636 * w32.h (dostounix_filename): Adjust prototype.
638 * msdos.c (dostounix_filename): Accept an additional argument and
640 (init_environment): Adjust callers of dostounix_filename.
642 * fileio.c (Ffile_name_directory, file_name_as_directory)
643 (directory_file_name, Fexpand_file_name)
644 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
646 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
648 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
649 variables, as egetenv is case-insensitive for DOS_NT.
651 * dired.c (file_name_completion): Don't call Fdirectory_file_name
652 with an encoded file name.
654 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
655 Adjust calls to dostounix_filename.
657 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
659 * unexw32.c (unexec): Adjust call to dostounix_filename.
661 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
663 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
666 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
669 * callproc.c (Fcall_process): Make sure program name in PATH and
670 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
671 is passed to exec/spawnve, which fails unless the file-name
674 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
675 even if w32-quote-process-args is nil.
677 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
679 Fix timestamp bug when write-region appends nothing (Bug#13149).
680 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
681 the file's time stamp doesn't change if Emacs happens to write nothing
682 to the file, and on a buggy file system this could cause Emacs to
683 incorrectly infer that the file system doesn't have the bug.
684 Avoid this problem by inhibiting the inference in this case.
686 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
688 * window.h (struct window): Convert base_line_number, base_line_pos
689 and column_number_displayed members from Lisp_Object to ptrdiff_t.
690 Convert region_showing member from Lisp_Object to bitfield.
691 Remove sequence_number member. Adjust comments.
692 * window.c (sequence_number): Remove.
693 (make_window): Initialize column_number_displayed.
694 * print.c (print_object): Follow the printed representation of
695 frames and print window pointer to distinguish between windows.
696 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
697 * xdisp.c (wset_base_line_number, wset_base_line_pos)
698 (wset_column_number_displayed, wset_region_showing): Remove.
699 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
700 (try_scrolling, try_cursor_movement, redisplay_window)
701 (try_window_reusing_current_matrix, try_window_id, display_line)
702 (display_mode_lines, decode_mode_spec): Adjust users.
703 * .gdbinit (pwinx): Do not print sequence_number.
705 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
707 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
708 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
709 * dired.c: Include <fcntl.h>.
710 (open_directory): New function, which uses open and fdopendir
711 rather than opendir. DOS_NT platforms still use opendir, though.
712 (directory_files_internal, file_name_completion): Use it.
713 (file_attributes): New function, with most of the old Ffile_attributes.
714 (directory_files_internal, Ffile_attributes): Use it.
715 (file_attributes, file_name_completion_stat): First arg is now fd,
716 not dir name. All uses changed. Use fstatat rather than lstat +
718 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
719 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
720 (emacs_readlinkat): New function, with much of the old
721 Ffile_symlink_p, but with an fd argument for speed.
722 It uses readlinkat rather than careadlinkatcwd, so that it
723 need not assume the working directory.
724 (Ffile_symlink_p): Use it.
725 * filelock.c (current_lock_owner): Use emacs_readlinkat
726 rather than emacs_readlink.
727 * lisp.h (emacs_readlinkat): New decl.
728 (READLINK_BUFSIZE, emacs_readlink): Remove.
729 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
730 (emacs_norealloc_allocator, emacs_readlink): Remove.
731 This stuff is moved to fileio.c.
732 * w32.c (fstatat, readlinkat): New functions.
733 (careadlinkat): Don't check that fd == AT_FDCWD.
734 (careadlinkatcwd): Remove; no longer needed.
736 2013-01-31 Glenn Morris <rgm@gnu.org>
738 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
739 (Fwrite_region): Update for new choose_write_coding_system args.
740 Move the last piece of choose_write_coding_system here. (Bug#13522)
741 (syms_of_fileio): Add choose-write-coding-system.
743 2013-01-30 Eli Zaretskii <eliz@gnu.org>
745 * w32.c (sys_open): Zero out the flags for the new file descriptor.
746 (sys_close): Zero out the flags for the file descriptor before
747 closing it. (Bug#13546)
749 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
750 (logon_network_drive, stat_worker, symlink, chase_symlinks):
751 Use CharNextExA and CharPrevExA to iterate over file names encoded in
754 * w32.c (w32_get_long_filename, init_environment, readlink):
755 Support file names encoded in DBCS codepages.
756 (readlink): Use the current file-name-coding-system, not the ANSI
757 codepage, to decode and handle targets of symlinks.
759 2013-01-28 Eli Zaretskii <eliz@gnu.org>
761 * w32.c (opendir): Now accepts a 'const char *'.
763 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
765 Remove obsolete redisplay code. See the discussion at
766 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
767 * dispnew.c (preemption_period, preemption_next_check): Remove.
768 (Vredisplay_preemption_period): Likewise.
769 (update_frame, update_single_window, update_window, update_frame_1):
770 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
771 used, following the 2012-06-22 change.
773 2013-01-25 Eli Zaretskii <eliz@gnu.org>
775 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
777 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
779 * font.c (num_fonts): Remove the leftover from old
780 debugging code. Adjust comment style here and there.
781 * insdel.c (insert_1): Remove.
782 * lisp.h (insert_1): Remove prototype.
783 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
785 2013-01-25 Eli Zaretskii <eliz@gnu.org>
787 * w32.c (max_filename_mbslen): New function.
788 (normalize_filename, readdir): Use it to detect locales where ANSI
789 encoding of file names uses a double-byte character set (DBCS).
790 If a DBCS encoding is used, advance by characters using
791 CharNextExA, instead of incrementing a 'char *' pointer.
792 Use _mbslwr instead of _strlwr. (Bug#13515)
794 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
795 request of memory reservation to 1.7GB. (Bug#13065)
797 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
799 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
800 at check_extra_latin label. (Bug#13505)
802 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
804 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
805 Avoid redundant calls to strlen.
807 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
809 Drop async_visible and async_iconified fields of struct frame.
810 This is possible because async input is gone; for details, see
811 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
812 * frame.h (struct frame): Remove async_visible and async_iconified
813 members, convert garbaged to unsigned bitfield. Adjust comments.
814 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
815 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
816 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
817 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
818 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
820 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
821 properly. Likewise for obscured.
823 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
826 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
828 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
830 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
831 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
833 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
835 * xdisp.c (message2, message2_nolog): Remove functions.
836 (message3, message3_nolog): Extract nbytes and multibyteness directly
837 from the string. Change all callers.
838 (message3_nolog): Don't set message_enable_multibyte since set_message
839 will reset it anyway.
840 (message1, message1_nolog): Use message3.
841 (vmessage): Use a stack allocated buffer rather than f->message_buf.
842 (with_echo_area_buffer): Remove last two arguments. Update all callers.
843 (set_message): Drop all but the second arg, which has to be a string.
844 (set_message_1): Simplify now that we know that a1 is NULL and the
845 second arg is a string.
846 * frame.h (struct frame): Remove `message_buf' field.
847 Use glyphs_initialized_p instead.
848 (FRAME_MESSAGE_BUF): Remove macro.
849 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
850 * lisp.h (message2, message2_nolog): Remove declarations.

853 (read_char_minibuf_menu_width): Remove vars.
854 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
855 to correctly handle multibyte strings.
856 * frame.c (delete_frame): Don't free message_buf any more.
857 * editfns.c (message_text, message_length): Remove vars.
858 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
859 * fileio.c (auto_save_error): Use message3 instead of message2.
860 * dispnew.c (adjust_frame_message_buffer): Remove function.
862 2013-01-23 Eli Zaretskii <eliz@gnu.org>
864 * w32term.c (w32fullscreen_hook): Account correctly for the screen
865 real estate used for the tool bar and the menu bar.
867 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
869 * insdel.c (prepare_to_modify_buffer): Force redisplay if
870 hidden buffer is prepared to modification (Bug#13164).
872 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
874 * window.h (struct window): Change window_end_valid member from
875 Lisp_Object to a bitfield. Adjust comments.

877 * window.c (adjust_window_count): Clear window_end_valid.
878 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
879 (Fwindow_line_height, set_window_buffer, Frecenter)
880 (Fsplit_window_internal, Fdelete_other_windows_internal)
881 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
882 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
883 * xdisp.c (check_window_end, reconsider_clip_changes)
884 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
885 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
886 (find_first_unchanged_at_end_row, try_window_id): Likewise.
888 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
890 * xdisp.c (mark_window_display_accurate): Simplify the loop
891 assuming that the only one of vchild, hchild or buffer window
892 slots is non-nil. Call mark_window_display_accurate_1 for
893 the leaf windows only.
894 (mark_window_display_accurate_1): Always assume leaf window.
897 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
899 * emacs.c (Qkill_emacs_hook): Now static.
901 * fileio.c (Finsert_file_contents): Simplify.
902 Remove unnecessary assignments and tests.
904 2013-01-21 Eli Zaretskii <eliz@gnu.org>
906 * w32.c (acl_set_file): Don't test for errors unless
907 set_file_security returns FALSE. Avoids spurious errors when
910 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
912 * fileio.c (Finsert_file_contents): Revert code introduced at
913 2013-01-18 in favor of the simpler and generally better fix.
914 Save stack space by removing 'buffer' and reusing 'read_buf'
917 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
919 * lisp.h (eabs): Define unconditionally (Bug#13419).
920 The old "#if !defined (eabs)" was an unnecessary revenant of back
921 when this macro was called "abs". Document 'eabs' better.
923 2013-01-19 Glenn Morris <rgm@gnu.org>
925 * fns.c (Frandom): Doc fix.
927 2013-01-19 Eli Zaretskii <eliz@gnu.org>
929 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
930 segfault when there are lots of overlays.
932 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
933 when there are lots of overlays.
934 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
935 for the details and a way to reproduce.
937 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
939 * fileio.c: Use O_APPEND to append.
940 This corresponds better to the natural interpretation of "append",
941 and avoids the need to open the output file twice, or to invoke
942 lseek when APPEND is neither nil nor a number.
943 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
944 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
945 file possibly twice, and lseeking to its end; this avoids the
946 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
947 at the same time: the combination is never needed and apparently
948 it doesn't work with DOS_NT.
950 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
951 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
953 Allow floating-point file offsets.
954 Problem reported by Vitalie Spinu in
955 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
956 * fileio.c (emacs_lseek): Remove.
957 (file_offset): New function.
958 (Finsert_file_contents, Fwrite_region): Use it.
960 2013-01-19 Chong Yidong <cyd@gnu.org>
962 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
963 aborting on Fsignal (Bug#13289).
965 2013-01-19 Eli Zaretskii <eliz@gnu.org>
967 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
968 set_file_security as failure due to insufficient privileges.

972 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
974 Work around bug in CIFS and vboxsf file systems (Bug#13149).
975 The bug was observed on Ubuntu operating inside a virtual machine,
976 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
977 The workaround introduces a race condition on non-buggy hosts,
978 but it's an unlikely race and anyway there's a nearly identical
979 nearby race that can't be fixed.
980 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
982 (Fwrite_region): Test for file system time stamp bug.
983 (init_fileio): New function.
984 * lisp.h (init_fileio): Declare it.

996 Free Lisp_Save_Value object used to pass parameters.
997 (read_non_regular_quit): Rename to read_contents_quit.
998 (Finsert_file_contents): Redesign internal file reading loop to adjust
999 gap and end positions after each read and so help make_gap to work
1000 properly. Do not signal an I/O error too early and so do not leave
1001 not yet decoded characters in a buffer, which was the reason of
1002 redisplay crash. Use list2 to build return value. Adjust comments.
1004 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1006 Close a race when statting and reading files (Bug#13149).
1007 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1008 This avoids a race if the file is renamed between stat and open.
1009 This race is not the problem originally noted in Bug#13149;
1010 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

1416 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
1418 * keyboard.c (record_asynch_buffer_change): Initialize an event
1419 only if it's really needed.
1420 * frame.h (enum output_method): Remove output_mac member since
1421 it's a leftover from the deleted code.
1422 * frame.c (Fframep): Adjust user here ...
1423 * terminal.c (Fterminal_live_p): ... and here.
1424 * coding.c (Qmac): Now here because it's only used to denote
1425 end-of-line encoding type.
1426 (syms_of_coding): DEFSYM it.
1427 * frame.h (Qmac): Remove duplicated declaration.
1429 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
1431 * window.c (select_window_1): Now static, since it's used only here.
1433 2012-12-25 Eli Zaretskii <eliz@gnu.org>
1435 * window.c (window_body_cols): Subtract display margins from the
1436 window body width on TTYs as well. See
1437 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
1438 for the original report.
1440 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
1442 * xdisp.c (redisplay_window): Remove inner local variable
1443 because the outer shadowed one has the same meaning.
1444 * xterm.h (struct x_output): Remove toolbar_detached member since it's
1446 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
1447 (xg_create_tool_bar): Adjust users.
1449 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
1451 * buffer.h (BUF_COMPACT): New macro to follow the common style.
1452 * buffer.c (Fget_buffer_create): Use it to set compact field of
1453 struct buffer_text to avoid accessing an uninitialized value
1454 when compact_buffer is called for the first time.
1455 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
1456 (Fset_buffer_modified_p): Use buffer_window_count to check
1457 whether the buffer is displayed in some window.
1458 * xdisp.c (message_dolog): Likewise.
1460 2012-12-23 Eli Zaretskii <eliz@gnu.org>
1462 * w32.c (acl_set_file): If setting the file security descriptor
1463 fails, and the new DACL is identical to the existing one, silently
1464 return success. This fixes problems for users backing up their
1465 own files without having the necessary privileges for setting
1466 security descriptors.
1468 * w32proc.c (reader_thread): Do not index fd_info[] with negative
1470 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
1471 after WaitForSingleObject returns normally. This expedites reader
1472 thread shutdown when delete_child triggers it.
1473 (reap_subprocess): More accurate commentary for why we call
1474 delete_child only when cp->fd is negative.
1476 * w32.c (sys_close): Do not call delete_child on a subprocess
1477 whose handle is not yet closed. Instead, set its file descriptor
1478 to a negative value, so that reap_subprocess will call
1479 delete_child on that subprocess when its SIGCHLD arrives.
1480 This avoids closing handles used for communications between sys_select
1481 and reader_thread, which doesn't give sys_select a chance to
1482 notice that the process exited and invoke the SIGCHLD handler for
1485 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
1487 * nsfns.m (Fns_do_applescript): Run event loop until script has
1488 been executed (Bug#12969).
1489 (ns_run_ascript): Chech as_script for nil, set to nil after
1492 2012-12-22 Martin Rudalics <rudalics@gmx.at>
1494 * window.c (Fselect_window): Reword doc-string (Bug#13248).
1496 2012-12-22 Eli Zaretskii <eliz@gnu.org>
1498 * w32term.c (w32fullscreen_hook): New function.
1499 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
1501 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1503 * fileio.c (Finsert_file_contents): Doc fix.
1505 * w32proc.c (new_child, delete_child, find_child_pid): For a
1506 subprocess, consider its slot being in use as long as its process
1507 handle (procinfo.hProcess) is not NULL. This avoids reusing the
1508 slot when a new process is started immediately after killing
1509 another one, without waiting enough time for the first process to
1510 be reaped and resources allocated for it be orderly freed.
1512 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1514 2012-12-21 Chong Yidong <cyd@gnu.org>
1516 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
1518 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
1520 2012-12-21 Eli Zaretskii <eliz@gnu.org>
1522 * w32.c (get_name_and_id): Always pass NULL as the first argument
1523 of lookup_account_sid. Avoids crashes with UNC file names that
1524 refer to DFS domains, not to specific machine names. (Bug#12621)
1525 Remove now unused argument FNAME; all callers changed.
1526 (get_file_owner_and_group): Remove now unused argument FNAME; all
1529 2012-12-21 Chong Yidong <cyd@gnu.org>
1531 * editfns.c (Finsert_char): Since read-char-by-name now signals an
1532 error for invalid chars, don't check for a nil return value.
1534 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1536 Avoid calls to CHAR_TO_BYTE if byte position is known.
1537 * editfns.c (make_buffer_string_both): Use move_gap_both.
1538 (Fbuffer_string): Use make_buffer_string_both.
1539 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
1541 (buf_bytepos_to_charpos): Likewise.
1542 (charpos_to_bytepos): Remove.
1543 * fileio.c (Finsert_file_contents): Use move_gap_both.
1544 * search.c (Freplace_match): Likewise.
1545 * process.c (process_send_region): Likewise. Use convenient
1546 names for byte positions.
1547 * lisp.h (charpos_to_bytepos): Remove prototype.
1548 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
1549 * insdel.c (move_gap): Likewise.
1551 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
1553 * xdisp.c (redisplay_internal): Remove now-unused local.
1555 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
1557 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
1558 (redisplay_internal): Don't bother selecting the frame to get the
1559 proper value of frame-local variables (bug#13225).
1561 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
1563 * textprop.c (set_text_properties_1): Do not allow NULL interval.
1564 Rename 4th argument since it may be buffer or string. Adjust comment.
1565 * intervals.c (graft_intervals_info_buffer): Find an interval here.
1567 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
1569 * coding.c (Fdetect_coding_region): Do not check start and end with
1570 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
1571 (code_convert_region): Likewise.
1573 2012-12-18 Eli Zaretskii <eliz@gnu.org>
1575 * w32.c (acl_get_file, acl_set_file): Run the file name through
1576 map_w32_filename, and resolve any symlinks in the file name, like
1578 (acl_set_file): Call revert_to_self, if any privileges were
1581 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
1583 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
1584 ($(BLD)/w32.$(O)): Update dependencies.
1586 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
1588 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
1589 propagate redisplay's scrolling (if any) to the right window.
1590 (redisplay_internal): Use ensure_selected_frame.
1591 (display_mode_lines): Complete last fix.
1592 * window.c (select_window_1): New func, extracted from select_window.
1593 (select_window): Use it.
1594 * window.h (select_window_1): Declare.
1596 2012-12-17 Eli Zaretskii <eliz@gnu.org>
1598 Emulate Posix ACL APIs on MS-Windows.
1599 * w32.c: Include sddl.h and sys/acl.h.
1600 (SDDL_REVISION_1): Define if not already defined.
1601 (g_b_init_get_security_descriptor_dacl)
1602 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
1603 (g_b_init_is_valid_security_descriptor)
1604 (g_b_init_set_file_security): New static flags.

1616 (acl_free, acl_get_file, acl_set_file): New functions.
1618 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
1620 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
1622 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
1623 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
1624 for some of that bug's symptoms can now cause Emacs to abort.
1625 Remove the workaround.
1626 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
1627 The bug that caused SIGCHLD to get lost has been fixed, and the
1628 workaround for it can now cause Emacs to abort.
1630 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
1632 * sysdep.c (emacs_abort): Bump backtrace size to 40.
1633 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
1634 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
1636 2012-12-16 Romain Francoise <romain@orebokech.com>
1638 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
1639 (Fcopy_file): Change last arg to `preserve_extended_attributes'
1640 and copy ACL entries of file in addition to SELinux context if set.
1641 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
1643 * Makefile.in (LIBACL_LIBS): New macro.
1646 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
1648 * fileio.c (internal_delete_file): Use bool for boolean.
1650 2012-12-15 Eli Zaretskii <eliz@gnu.org>
1652 Fix bug #13079 on MS-Windows with temp files not being deleted.

1655 (register_child): First argument is now pid_t.
1656 (record_infile, record_pending_deletion): New prototypes.
1658 * w32proc.c (new_child): Initialize input_file and
1659 pending_deletion members of the child.
1660 (delete_child): Delete the child's temporary input file, if any,
1661 that is pending deletion.
1662 (register_child): First argument is now pid_t.
1663 (record_infile, record_pending_deletion): New functions.
1664 (reap_subprocess): Fix a typo in DebPrint string.
1665 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
1667 * fileio.c (internal_delete_file): Return an int again: non-zero
1668 if delete-file succeeds, zero otherwise.
1670 * lisp.h (internal_delete_file): Adjust prototype.
1672 * callproc.c (Fcall_process): Don't overwrite infile with result
1674 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
1675 asynchronous subprocess, record the name of the input file name,
1677 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
1678 delete the file, record it as pending deletion when the subprocess
1681 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1683 * editfns.c [HAVE_PWD_H]: Include grp.h.
1685 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
1687 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
1689 Fix permissions bugs with setgid directories etc. (Bug#13125)
1690 * dired.c (Ffile_attributes): Return t as the 9th attribute,
1691 to mark it as a placeholder. The old value was often wrong.
1692 The only user of this attribute has been changed to use
1693 file-ownership-preserved-p instead, with its new group arg.
1694 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
1696 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>

1701 2012-12-14 Eli Zaretskii <eliz@gnu.org>
1703 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
1704 try to get accurate owner and group information from NT file
1705 security APIs. This is to make most callers of 'stat' and
1706 'lstat', which don't need that information, much faster.
1708 * dired.c (Ffile_attributes) [WINDOWSNT]:
1709 Set w32_stat_get_owner_group to a non-zero value, to request accurate
1710 owner and group information from 'lstat'.
1712 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1714 * fileio.c (Finsert_file_contents): Don't put tail into head area,
1715 as that confuses set-auto-coding, so insist on the head-read
1716 returning the full 1024 bytes. Let lseek compute the tail offset;
1717 less work for us. Do not ignore I/O errors when reading the tail.
1719 * xdisp.c: Minor style fixes.
1720 (init_iterator): Hoist assignment out of if-expression.
1721 (markpos_of_region): Callers now test for sign, not for -1.
1723 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
1725 Minor redisplay optimization when the region length is zero.
1726 * xdisp.c (markpos_of_region): New function.
1727 (init_iterator): Do not highlight the region of zero length.
1728 (redisplay_window): Check whether the region is of non-zero length.
1729 (try_cursor_movement): Allow if the region length is zero.
1730 (try_window_reusing_current_matrix, try_window_id): Likewise.
1732 2012-12-13 Eli Zaretskii <eliz@gnu.org>
1734 * search.c (search_buffer): Check the inverse translations of each
1735 character in pattern when the buffer being searched is unibyte.
1738 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1740 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
1741 files, fixing a regression from 24.2.
1742 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
1744 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
1746 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
1747 fstat shouldn't fail, and if it does fail copy-file should not proceed.
1748 Remove unnecessary S_ISLNK test, as (contra the comments) this
1749 function can't copy symlinks. Improve quality of error message
1750 when attempting to copy files that are neither regular files nor

1758 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
1759 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
1761 2012-12-12 Daniel Colascione <dancol@dancol.org>
1763 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
1764 the dumped Emacs is not a sparse file, greatly improving Cygwin
1765 "make bootstrap" performance.
1767 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
1769 * inotify.c (inotify_callback): Generate an Emacs event for every
1770 incoming inotify event.
1772 2012-12-11 Eli Zaretskii <eliz@gnu.org>
1774 * xdisp.c (handle_face_prop): Fix logic of computing
1775 it->start_of_box_run_p.
1776 (append_space_for_newline): If the glyph row is R2L, reset the
1777 iterator's end_of_box_run_p flag before prepending the space glyph.
1778 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
1779 iterator's start_of_box_run_p flag before prepending the stretch.
1780 (append_glyph, produce_image_glyph, append_composite_glyph)
1781 (append_stretch_glyph, append_glyphless_glyph): Reverse the
1782 left_box_line_p and right_box_line_p flags of the glyph for R2L
1783 glyph rows. (Bug#13011)
1785 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1787 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
1788 if changed buffer is not shown in a window.
1789 * insdel.c (prepare_to_modify_buffer): Likewise.
1790 * window.c (replace_buffer_in_windows_safely): Do nothing
1791 if buffer is not shown in a window.

1797 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
1798 encoded_file_name, which is what it is.
1800 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
1802 Consistently use marker_position and marker_byte_position.
1803 * fringe.c (Ffringe_bitmaps_at_pos):

1810 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
1811 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
1812 Replace direct access to marker fields with calls
1813 to marker_position and/or marker_byte_position.
1815 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
1817 * makefile.w32-in (SIG2STR_H): New macro.
1818 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
1819 ($(BLD)/w32notify.$(O)): Update dependencies.

1824 Windows file notification functionality unless WINDOWSNT.
1826 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
1829 * w32fns.c (cache_system_info): Initialize the global hinst
1830 variable here so various initialization calls DTRT.
1832 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
1833 (hinst): Remove unneeded extern declaration.
1834 (_start): Remove initialization of above variables; remove
1835 initialization of hinst, as cache_system_info now does that.
1837 * emacs.c (main): Call cache_system_info early in startup; we
1838 previously weren't calling it in Cygwin builds.
1840 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
1841 Teach the autoconf build system how to compile a Windows resource file
1842 and link it to Emacs.

1979 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
1981 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
1982 * alloc.c (xputenv): New function.
1983 * dbusbind.c (Fdbus_init_bus):
1985 * xterm.c (x_term_init):

1996 no longer needed here.
1997 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
1998 Move to inside set_time_zone_rule; they don't need file scope any more.
1999 (set_time_zone_rule): Maintain the TZ=value string separately.
2000 (syms_of_editfns): Don't initialize initial_tz;
2001 init_editfns now does it.
2002 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2003 * lisp.h (xputenv): New decl.
2005 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

2016 informative (Bug#12992).
2018 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2020 Simplify get_lim_data.
2021 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2022 Remove USG and vlimit methods; no longer used these days.
2023 Add #error catchall just in case.
2025 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2026 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2027 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.

2049 This will cause a production Emacs to dump core instead of
2052 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2054 * frame.c (make_frame): Do not set window's buffer to t.
2055 * window.c (Fsplit_window_internal): Likewise. Previously it was
2056 used to indicate that the window is being set up. Now we use
2057 set_window_buffer for all new windows, so the condition in ...
2058 (Fset_window_buffer): ... is always true and can be removed.
2060 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2062 Convenient macro to check whether the buffer is hidden.
2063 * buffer.h (BUFFER_HIDDEN_P): New macro.
2064 * frame.c (make_frame): Use it. Adjust comment.
2065 * buffer.c (candidate_buffer): New function.
2066 (Fother_buffer, other_buffer_safely): Use it.

2090 * callproc.c, process.h (record_kill_process):
2091 New function, containing part of the old call_process_kill.
2092 (call_process_kill): Use it.
2093 This does not change call_process_kill's behavior.
2094 * process.c (Fdelete_process): Use record_kill_process to fix a
2095 race condition that could cause Emacs to lose track of a child.
2097 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2099 Avoid code duplication between prev_frame and next_frame.
2100 * frame.c (candidate_frame): New function. Add comment.
2101 (prev_frame, next_frame): Use it. Adjust comment.
2103 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2105 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2106 fails, signal an error instead of continuing with an empty
2108 Encode expanded temp file pattern before passing it to mkstemp or
2111 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2112 Encode the file name before passing it to dostounix_filename, in
2113 case it will downcase it (under w32-downcase-file-names).
2116 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2118 Minor call-process cleanups.
2119 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2120 at the same time as other platforms, to simplify analysis.
2121 No need for fd0_volatile since we have synch_process_fd.
2122 Avoid needless emacs_close; arg is always negative.
2124 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2126 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2129 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2131 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2132 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2133 and mouse_face_hidden members to a bitfields.
2134 * frame.h (struct frame): Remove set-but-not-used space_width member.
2135 (FRAME_SPACE_WIDTH): Remove.
2136 * nsterm.m, w32term.c, xterm.c: Adjust users.
2137 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2138 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2139 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2140 members to a bitfields.
2142 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2144 Don't let call-process be a zombie factory (Bug#12980).
2145 Fixing this bug required some cleanup of the signal-handling code.
2146 As a side effect, this change also fixes a longstanding rare race
2147 condition whereby Emacs could mistakenly kill unrelated processes,
2148 and it fixes a bug where a second C-g does not kill a recalcitrant
2149 synchronous process in GNU/Linux and similar platforms.
2150 The patch should also fix the last vestiges of Bug#9488,
2151 a bug which has mostly been fixed on the trunk by other changes.
2152 * callproc.c, process.h (synch_process_alive, synch_process_death)
2153 (synch_process_termsig, sync_process_retcode):
2154 Remove. All uses removed, to simplify analysis and so that
2155 less consing is done inside critical sections.
2156 * callproc.c (call_process_exited): Remove. All uses replaced
2157 with !synch_process_pid.
2158 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2159 These take the role of what used to be in unwind-protect arg.
2161 (block_child_signal, unblock_child_signal):
2162 New functions, to avoid races that could kill innocent-victim processes.
2163 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2164 (call_process_kill): Record killed processes as deleted, so that
2165 zombies do not clutter up the system. Do this inside a critical
2166 section, to avoid a race that would allow the clutter.
2167 (call_process_cleanup): Fix code so that the second C-g works again
2168 on common platforms such as GNU/Linux.
2169 (Fcall_process): Create the child process in a critical section,
2170 to fix a race condition. If creating an asynchronous process,
2171 record it as deleted so that zombies do not clutter up the system.
2172 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2173 light of these changes. Omit unnecessary call to emacs_close
2174 before failure, as the unwind-protect code does that.
2175 * callproc.c (call_process_cleanup):
2176 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2177 * process.c (record_deleted_pid): New function, containing
2178 code refactored out of Fdelete_process.
2179 (Fdelete_process): Use it.
2180 (process_status_retrieved): Remove. All callers changed to use
2181 child_status_change.
2182 (record_child_status_change): Remove, folding its contents into ...
2183 (handle_child_signal): ... this signal handler. Now, this
2184 function is purely a handler for SIGCHLD, and is not called after
2185 a synchronous waitpid returns; the synchronous code is moved to
2186 wait_for_termination. There is no need to worry about reaping
2187 more than one child now.
2188 * sysdep.c (get_child_status, child_status_changed): New functions.
2189 (wait_for_termination): Now takes int * status and bool
2190 interruptible arguments, too. Do not record child status change;
2191 that's now the caller's responsibility. All callers changed.
2192 Reimplement in terms of get_child_status.
2193 (wait_for_termination_1, interruptible_wait_for_termination):
2194 Remove. All callers changed to use wait_for_termination.
2195 * syswait.h: Include <stdbool.h>, for bool.
2196 (record_child_status_change, interruptible_wait_for_termination):
2198 (record_deleted_pid, child_status_changed): New decls.
2199 (wait_for_termination): Adjust to API changes noted above.
2201 * bytecode.c, lisp.h (Qbytecode): Remove.
2202 No longer needed after 2012-11-20 interactive-p changes.
2204 2012-12-03 Eli Zaretskii <eliz@gnu.org>
2206 * xdisp.c (redisplay_window): If the cursor is visible, but inside
2207 the scroll margin, move point outside the margin. (Bug#13055)
2209 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
2211 * gtkutil.c (my_log_handler): New function.
2212 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
2214 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2216 * lisp.h (modify_region): Rename to...
2217 (modify_region_1): ...new prototype.
2218 * textprop.c (modify_region): Now static. Adjust users.
2219 * insdel.c (modify_region): Rename to...
2220 (modify_region_1): ...new function to work with current buffer.
2221 Adjust comment and users. Use true and false for booleans.
2223 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
2225 * alloc.c (free_save_value): New function.
2226 (safe_alloca_unwind): Use it.
2227 * lisp.h (free_save_value): New prototype.
2228 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
2230 (save_excursion_restore): Adjust to match saved data structure.
2231 Use free_save_value to offload some work from GC. Drop obsolete
2234 2012-12-03 Chong Yidong <cyd@gnu.org>
2236 * fileio.c (Vauto_save_list_file_name): Doc fix.
2238 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
2240 * w32fns.c: Remove prototype of atof.
2241 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
2243 (file_dialog_callback): Make it UINT_PTR.
2245 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
2248 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2249 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
2252 2012-12-03 Glenn Morris <rgm@gnu.org>
2254 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
2256 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
2258 Fix xpalloc confusion after memory is exhausted.
2259 * alloc.c (xpalloc): Comment fix.
2260 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
2261 and signals an error, do not clear charset_table_size, as
2262 charset_table is still valid.
2263 * doprnt.c (evxprintf): Clear *BUF after freeing it.
2265 Use execve to avoid need to munge environ (Bug#13054).
2266 * callproc.c (Fcall_process):
2267 * process.c (create_process):
2268 Don't save and restore environ; no longer needed.
2269 * callproc.c (child_setup):
2270 Use execve, not execvp, to preserve environ.
2272 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
2274 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
2276 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2278 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
2279 display for sliced images (Bug#10500).

2283 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
2285 * doc.c (Fdocumentation): Re-add handling of function-documentation,
2286 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
2288 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
2290 * xdisp.c (window_outdated): Remove eassert since it hits
2291 some suspicious corner cases (see Bug#13007 and Bug#13012).
2292 (mode_line_update_needed): New function.
2293 (redisplay_internal, redisplay_window): Use it.

2297 (buffer_shared_and_changed): ...near to its real use.
2299 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
2301 * callproc.c (Fcall_process): Don't misreport vfork failure.
2303 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
2305 * callproc.c (Fcall_process): Fix vfork portability problems.
2306 Do not assume that fd[0], count, filefd, and save_environ survive
2307 vfork. Fix bug whereby wrong errno value could be reported for
2308 pipe failure. Some minor cleanups, too, as follows. Move buf and
2309 bufsize to the context where they're needed. Change new_argv to
2310 be of type char **, as this is more convenient and avoids casts.
2311 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
2312 Now local constants, not macros.
2314 2012-11-18 Kenichi Handa <handa@gnu.org>

2358 * keyboard.c (HAVE_MOUSE):
2359 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
2360 were always defined.
2362 2012-11-24 Eli Zaretskii <eliz@gnu.org>
2364 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
2365 between bpos_covered and bpos_max. This fixes cursor display when
2366 several display strings follow each other.
2368 * .gdbinit (pgx): If the glyph's object is a string, display the
2369 pointer to string data, rather than the value of the string object
2370 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
2372 * indent.c (Fvertical_motion): If the starting position is covered
2373 by a display string, return to one position before that, to avoid
2374 overshooting it inside move_it_to. (Bug#12930)
2376 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
2378 * frame.h (struct frame): Remove display_preempted member
2379 since all users are dead long ago.
2380 * nsterm.h (struct x_output): Use the only dummy member.
2381 * w32menu.c (pending_menu_activation): Remove since not
2383 (set_frame_menubar): Adjust user.
2384 * w32term.h (struct x_output): Drop outdated #if 0 code.
2385 (struct w32_output): Use bitfields for explicit_parent,
2386 asked_for_visible and menubar_active members.
2387 Drop unused pending_menu_activation member.
2388 * xterm.h (struct x_output): Drop outdated #if 0 code.
2389 Use bitfields for explicit_parent, asked_for_visible,
2390 has_been_visible and net_wm_state_hidden_seen members.
2392 2012-11-23 Eli Zaretskii <eliz@gnu.org>
2394 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
2395 of a literal "/". (Bug#12955)
2396 (gl-stamp): Invoke fc.exe directly, not through cmd.
2398 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
2400 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
2401 * dired.c: Assume HAVE_DIRENT_H.
2402 (NAMLEN): Remove, replacing with ...
2403 (dirent_namelen): New function. All uses changed. Use the GNU macro
2404 _D_EXACT_NAMELEN if available, as it's faster than strlen.
2405 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
2406 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
2407 * makefile.w32-in (DIR_H): Remove. All uses replaced with
2409 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
2410 * ndir.h: Rename to ../nt/inc/dirent.h.
2411 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
2412 Do not include <dirent.h>; no longer needed.
2413 * w32.c: Include <dirent.h> rather than "ndir.h".
2415 2012-11-23 Chong Yidong <cyd@gnu.org>
2417 * xftfont.c (xftfont_open): Remove duplicate assignment.
2419 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2421 * alloc.c (Fgarbage_collect): Unblock input after clearing
2422 gc_in_progress to avoid note_mouse_highlight glitch with GC.
2423 * frame.h (FRAME_MOUSE_UPDATE): New macro.
2424 * msdos.c (IT_frame_up_to_date): Use it here...
2425 * w32term.c (w32_frame_up_to_date): ...here...
2426 * xterm.c (XTframe_up_to_date): ...and here...
2427 * nsterm.m (ns_frame_up_to_date): ...but not here.
2428 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
2430 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
2431 Do not check whether GC is in progress.
2433 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
2435 * xdisp.c (window_buffer_changed): New function.
2436 (update_menu_bar, update_tool_bar): Use it to
2437 simplify large 'if' statements.
2438 (redisplay_internal): Generalize commonly used
2439 'tail' and 'frame' local variables.
2441 2012-11-22 Eli Zaretskii <eliz@gnu.org>
2443 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
2444 with Windows system header.
2446 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
2448 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
2449 * alloc.c: Assume unistd.h exists.
2450 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
2451 * sysdep.c (get_current_dir_name): Assume getcwd exists.
2452 (getwd) [USG]: Remove; no longer needed.
2453 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
2454 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
2455 * w32.h (getcwd): Remove decl.
2457 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
2459 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
2460 Make it set selected_window as well.
2461 (update_tool_bar): Use it.
2463 2012-11-21 Ken Brown <kbrown@cornell.edu>
2465 * emacs.c (main): Set the G_SLICE environment variable for all
2466 Cygwin builds, not just GTK builds. See
2467 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
2469 2012-11-21 Eli Zaretskii <eliz@gnu.org>
2471 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
2472 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
2473 Define for the MSVC compiler.
2475 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
2477 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
2478 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
2479 dostounix_filename. Prevents crashes down the road, because
2480 dostounix_filename assumes it gets a unibyte string.
2481 Reported by Michel de Ruiter <michel@sentient.nl>, see
2482 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
2484 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2486 Conflate Qnil and Qunbound for `symbol-function'.
2487 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
2488 * lread.c (init_obarray): Set `function' fields to Qnil.
2489 * eval.c (Fcommandp): Ignore Qunbound.
2490 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
2491 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
2492 Test NILP rather than Qunbound.
2493 (Ffmakunbound): Set to Qnil.
2494 (Fsymbol_function): Never signal an error.
2495 (Finteractive_form): Ignore Qunbound.
2497 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
2499 * eval.c (interactive_p): Remove no-longer-used decl.
2501 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
2503 * xdisp.c (buffer_shared): Adjust comment.
2504 (buffer_shared_and_changed): New function.
2505 (prepare_menu_bars, redisplay_internal): Use it to
2506 decide whether all windows or frames should be updated.
2507 (window_outdated): New function.
2508 (text_outside_line_unchanged_p, redisplay_window): Use it.
2509 (redisplay_internal): Likewise. Fix indentation.
2511 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
2513 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
2514 (syms_of_eval): Remove corresponding defsubr.
2515 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
2517 2012-11-19 Daniel Colascione <dancol@dancol.org>
2519 * w32fns.c (Fx_file_dialog):
2520 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
2521 cygwin_convert_file_name*.
2523 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
2524 Rename cygwin_convert_path* to cygwin_convert_file_name*.
2526 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
2528 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
2530 2012-11-18 Eli Zaretskii <eliz@gnu.org>
2532 * w32select.c: Include w32common.h before w32term.h, so that
2533 windows.h gets included before w32term.h uses some of its
2534 features, see below.
2536 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
2538 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
2540 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
2542 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
2544 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
2545 (ns_select): Return at once if events are held (Bug#12834).
2547 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
2549 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
2550 Needed following 2012-10-20 change. (Bug#12902)
2552 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
2554 * w32proc.c (waitpid): Remove unused label get_result.
2556 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
2558 * makefile.w32-in (SYSWAIT_H): New macro.
2559 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
2560 ($(BLD)/sysdep.$(O)): Update dependencies.
2562 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2564 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
2565 * callproc.c (relocate_fd): Assume F_DUPFD.
2566 * emacs.c, term.c (O_RDWR): Remove.
2567 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
2568 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
2569 * nsterm.m: Assume <fcntl.h> exists.
2570 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
2571 (create_pty, Fmake_network_process, server_accept_connection)
2572 (wait_reading_process_output, init_process_emacs):
2574 (wait_reading_process_output): Put in a special case for WINDOWSNT
2575 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
2576 It's not clear this is needed, but it's a more-conservative change.
2577 (create_process): Assume FD_CLOEXEC.
2578 (create_process, create_pty): Assume O_NOCTTY.
2579 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
2580 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
2581 Omit if not DOS_NT, since F_GETFL is not defined there.
2582 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
2583 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
2585 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
2586 lack it, since gnulib guarantees this.
2587 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
2589 2012-11-17 Eli Zaretskii <eliz@gnu.org>
2591 * w32.c (faccessat): Pretend that directories have the execute bit
2592 set. Emacs expects that, e.g., in files.el:cd-absolute.
2594 * w32proc.c (create_child): Don't clip the PID of the child
2595 process to fit into an Emacs integer, as this is no longer a
2597 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
2598 reaping only the process specified by PID argument, if that is
2599 positive. Use PID instead of dead_child to know which process to
2600 reap. Wait for the child to die only if WNOHANG is not in
2602 (sys_select): Don't set dead_child.
2604 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
2605 as it is no longer needed.
2607 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
2609 (record_child_status_change): Remove the setting of
2610 record_at_most_one_child for the !WNOHANG case.
2612 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
2614 Fix problems in ns port found by static checking.
2615 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
2616 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
2617 not to process group.
2618 (ns_select): Use emacs_write, not write, as that's more robust
2619 in the presence of signals.
2620 (fd_handler:): Check for read errors.
2622 2012-11-16 Glenn Morris <rgm@gnu.org>
2624 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
2626 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
2628 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
2630 2012-11-16 Eli Zaretskii <eliz@gnu.org>
2632 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
2633 use the same value of thread handle.
2634 (start_timer_thread): If the timer thread exited (due to error),
2635 clean up by closing the two handles it used. Duplicate the caller
2636 thread's handle here, so it gets duplicated only once, when
2637 launching the timer thread. Set priority of the timer thread, not
2639 (getitimer): Don't duplicate the caller thread's handle here.
2642 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
2644 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
2647 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
2649 Remove no-longer-used pty_max_bytes variable.
2650 * process.c (pty_max_bytes): Remove; unused.
2651 (send_process): Do not set it.
2653 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
2655 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
2656 Update dependencies.
2658 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
2660 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
2661 This follows up on the 2012-09-29 patch that removed indirection
2662 for the 'function' field. Reported by Sergey Vinokurov in
2663 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
2665 2012-11-14 Eli Zaretskii <eliz@gnu.org>
2667 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
2668 different name, as the MS runtime does not have such a function,
2669 and probably never will.) All callers changed. Ignore DIRFD
2670 value if PATH is an absolute file name, to match Posix spec
2671 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
2674 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
2676 * xdisp.c (echo_area_display, redisplay_internal):
2677 Omit redundant check whether frame_garbaged is set.
2679 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
2681 Use faccessat, not access, when checking file permissions (Bug#12632).
2682 This fixes a bug that has been present in Emacs since its creation.
2683 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
2684 which must set some sort of record. (Torek's bug report was against
2685 a predecessor of GNU Emacs, but GNU Emacs happened to have the
2686 same common flaw.) See Torek's Usenet posting
2687 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
2688 Posted: Fri Apr 8 14:18:56 1983.
2689 * Makefile.in (LIB_EACCESS): New macro.
2691 * callproc.c (init_callproc):
2692 * charset.c (init_charset):
2693 * fileio.c (check_existing, check_executable, check_writable)
2695 * lread.c (openp, load_path_check):
2696 * process.c (allocate_pty):
2698 Use effective UID when checking permissions, not real UID.
2699 * callproc.c (init_callproc):
2700 * charset.c (init_charset):
2701 * lread.c (load_path_check, init_lread):
2702 Test whether directories are accessible, not merely whether they exist.
2703 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
2704 * fileio.c (check_existing, check_executable, check_writable)
2706 Use symbolic names instead of integers for the flags, as they're
2708 (check_writable): New arg AMODE. All uses changed.
2709 Set errno on failure.
2710 (Ffile_readable_p): Use faccessat, not stat + open + close.
2711 (Ffile_writable_p): No need to call check_existing + check_writable.
2712 Just call check_writable and then look at errno. This saves a syscall.
2713 dir should never be nil; replace an unnecessary runtime check
2714 with an eassert. When checking the parent directory of a nonexistent
2715 file, check that the directory is searchable as well as writable, as
2716 we can't create files in unsearchable directories.
2717 (file_directory_p): New function, which uses 'stat' on most platforms
2718 but faccessat with D_OK (for efficiency) if WINDOWSNT.
2719 (Ffile_directory_p, Fset_file_times): Use it.
2720 (file_accessible_directory_p): New function, which uses a single
2721 syscall for efficiency.
2722 (Ffile_accessible_directory_p): Use it.
2723 * xrdb.c (file_p): Use file_directory_p.
2724 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
2725 * lread.c (openp): When opening a file, use fstat rather than
2726 stat, as that avoids a permissions race. When not opening a file,
2727 use file_directory_p rather than stat.
2728 (dir_warning): First arg is now a usage string, not a format.
2729 Use errno. All uses changed.
2730 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
2731 that merely introduced a race.
2732 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
2733 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
2734 and similarly for the other O_* flags.
2735 * w32.c (sys_faccessat): Rename from sys_access and switch to
2736 faccessat's API. All uses changed.
2737 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
2738 (magic_db): Rename from magic_file_p.
2739 (magic_db, search_magic_path): Return an XrmDatabase rather than a
2740 char *, so that we don't have to test for file existence
2741 separately from opening the file for reading. This removes a race
2742 fixes a permission-checking problem, and simplifies the code.
2744 (file_p): Remove; no longer needed.
2746 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
2748 Omit glyphs initialization at startup.
2749 * dispnew.c (glyphs_initialized_initially_p): Remove.
2750 (adjust_frame_glyphs_initially): Likewise. Adjust users.
2751 (Fredraw_frame): Move actual code from here...
2752 (redraw_frame): ...to here. Add eassert. Adjust comment.
2753 (Fredraw_display): Use redraw_frame.
2754 * xdisp.c (clear_garbaged_frames): Likewise.
2756 2012-11-13 Eli Zaretskii <eliz@gnu.org>
2758 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
2759 passed to pint2str and pint2hrstr to be at most the size of the
2760 frame's decode_mode_spec_buffer. This avoids crashes with very
2761 large values of FIELD_WIDTH argument to decode_mode_spec.
2764 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
2766 Fix a race with verify-visited-file-modtime (Bug#12863).
2767 Since at least 1991 Emacs has ignored an mtime difference of no
2768 more than one second, but my guess is that this was to work around
2769 file system bugs that were fixed long ago. Since the race is
2770 causing problems now, let's remove that code.
2771 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
2772 whose time stamp is off by no more than a second. Insist that the
2773 file time stamps match exactly.
2775 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2777 * frame.h (struct frame): Convert external_tool_bar member to
2778 1-bit unsigned bitfield.
2779 * termhooks.h (struct terminal): Remove mouse_moved member since
2780 all users are long dead. Adjust comment on mouse_position_hook.
2782 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
2784 Simplify by using FOR_EACH_FRAME here and there.
2785 * frame.c (next_frame, prev_frame, other_visible_frames)
2786 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
2787 * w32term.c (x_window_to_scroll_bar): Likewise.
2788 * window.c (window_list): Likewise.
2789 * xdisp.c (x_consider_frame_title): Likewise.
2790 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
2791 * xfns.c (x_window_to_frame, x_any_window_to_frame)
2792 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
2793 * xmenu.c (menubar_id_to_frame): Likewise.
2794 * xselect.c (frame_for_x_selection): Likewise.
2795 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
2796 (x_window_to_menu_bar): Likewise.
2797 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
2799 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
2801 * data.c (Qdefalias_fset_function): Now static.
2803 Another tweak to vectorlike_header change.

2805 Remove, and replace all uses with ...
2806 (next_in_free_list, set_next_in_free_list):
2807 New functions, which respect C's aliasing rules better.
2809 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
2811 * window.c (list4i): Rename from 'quad'. All uses changed.
2812 Needed because <sys/types.h> defines 'quad' on Solaris 10.
2814 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
2816 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence

2824 (Fset_window_combination_limit): Fix doc-string.
2826 2012-11-10 Eli Zaretskii <eliz@gnu.org>
2828 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
2829 amount when the scroll margins are too large. When scrolling
2830 backwards in the buffer, give up if cannot reach point or the
2831 scroll margin within a reasonable number of screen lines.
2832 Fixes point position in window under scroll-up/down-aggressively when
2833 point is positioned many lines beyond the window top/bottom.
2836 * ralloc.c (relinquish): If real_morecore fails to return memory
2837 to the system, don't crash; instead, leave the last heap
2838 unchanged and return. (Bug#12774)

2847 (Finteractive_form): Simplify.
2848 (Fquo): Don't insist on having at least 2 arguments.
2849 (Qdefalias_fset_function): New var.
2851 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2853 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

2859 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2861 Fix recently introduced crash on MS-Windows (Bug#12839).
2862 * w32term.h (struct scroll_bar): Use convenient header.
2863 (SCROLL_BAR_VEC_SIZE): Remove.
2864 * w32term.c (x_scroll_bar_create): Use VECSIZE.
2866 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
2868 Tweak last vectorlike_header change.
2869 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
2870 vectorlike object on the free list. This is introduced to avoid
2871 some (but not all) pointer casting and aliasing problems, see
2872 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
2873 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

2877 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
2879 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
2880 been removed, so remove them here also.
2882 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
2884 * doc.c (Fdocumentation): Handle new property
2885 dynamic-docstring-function to replace the old ad-advice-info.
2887 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
2889 * fns.c (Qeql, hashtest_eq): Now static.
2891 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2893 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
2894 * fns.c (hashfn_eq, hashfn_eql, sxhash):
2895 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

2900 Use same hash function for hashfn_profiler as for hash_string etc.
2901 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
2902 * lisp.h (sxhash_combine): New inline function, with the contents
2903 of the old SXHASH_COMBINE.
2904 * profiler.c (hashfn_profiler): Use it, instead of having a
2905 special hash function containing a comparison that always yields 1.
2907 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2909 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
2910 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
2911 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
2914 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
2916 * image.c (xpm_make_color_table_h): Fix compiler error because
2917 make_hash_table changed.
2919 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
2921 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
2923 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
2925 Use ad-hoc comparison function for the profiler's hash-tables.
2926 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
2927 (make_log): Use them.
2928 (handle_profiler_signal): Don't inhibit quit any longer since we don't
2929 call Fequal any more.

2938 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
2939 (hash_lookup, hash_remove_from_table): Move assertion checking of
2940 hashfn result here. Check hash-equality before calling cmpfn.

2942 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
2943 (syms_of_fns): Initialize them.

2950 2012-11-08 Eli Zaretskii <eliz@gnu.org>
2952 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
2953 value of w32-scroll-lock-modifier is neither nil nor one of the
2954 known key modifiers. (Bug#12806)
2956 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
2958 Shrink struct vectorlike_header to the only size field.
2959 * lisp.h (enum pvec_type): Avoid explicit enum member values.
2961 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
2962 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
2963 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
2964 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
2965 information from the vector header. Adjust comment.

2980 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
2981 (large_vectors): Change type to struct large_vector.
2982 (allocate_vector_from_block): Simplify.
2983 (PSEUDOVECTOR_NBYTES): Replace with...
2984 (vector_nbytes): ...new function. Adjust users.
2985 (sweep_vectors): Adjust processing of large vectors.
2986 (allocate_vectorlike): Likewise.
2987 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
2988 Add easserts. Adjust XSETPVECTYPESIZE usage.
2989 (allocate_buffer): Use BUFFER_PVEC_INIT.
2990 (live_vector_p): Adjust to match large vector.
2991 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
2992 * buffer.h (struct buffer): Add next member.
2993 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
2995 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
2996 * fns.c (internal_equal): Adjust to match enum pvec_type change.

3001 (xvecsize): New command.
3003 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3005 * keyboard.c (event_to_kboard): Do not dereference
3006 frame_or_window field of SELECTION_REQUEST_EVENT
3007 and SELECTION_CLEAR_EVENT events (Bug#12814).
3008 * xterm.h (struct selection_input_event): Adjust comment.
3010 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3012 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3013 such as Scroll Lock, if the respective keys are treated as
3014 function keys, not as modifiers. This avoids destroying non-ASCII
3015 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3017 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3019 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3021 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3023 Restore some duplicate definitions (Bug#12814).
3024 This undoes part of the 2012-11-03 changes. Some people build
3025 with plain -g rather than with -g3, and they need the duplicate
3026 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3027 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3028 Define as macros, as well as as enums or as constants.
3030 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3032 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3033 to keypad keys (Bug#12816).
3035 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3037 Minor adjustments of recently-changed frame functions.
3038 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3039 known to be a frame (we're in the FRAMEP branch).
3040 * lisp.h (Qframep): Remove decl. frame.h declares this.
3041 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3042 since they're meant for Lisp fixnum values.
3044 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3046 * window.c (Fwindow_combination_limit): Revert to the only
3047 required argument and adjust docstring as suggested in
3048 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3049 by Martin Rudalics <rudalics@gmx.at>.
3051 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3053 Widely used frame validity and checking functions.
3054 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3055 * frame.c (decode_live_frame, decode_any_frame): New functions.
3056 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3057 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3058 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
3059 (Fframe_pointer_visible_p): Use decode_any_frame.
3060 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
3061 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
3062 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3063 (Fframe_focus): Likewise. Allow zero number of arguments.
3065 (frame_buffer_list, frame_buffer_predicate): Remove.
3066 * lisp.h (frame_buffer_predicate): Remove prototype.
3067 * buffer.c (Fother_buffer): Use decode_any_frame.
3068 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3069 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3070 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3071 (Fclose_font, Ffont_info): Use decode_live_frame.
3072 * fontset.c (check_fontset_name): Likewise.
3073 * terminal.c (Fframe_terminal): Likewise.
3074 * w32fns.c (check_x_frame): Likewise.
3075 * window.c (Fminibuffer_window, Fwindow_at)
3076 (Fcurrent_window_configuration): Likewise.
3077 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3078 Likewise. Allow zero number of arguments. Adjust docstring.
3079 * dispnew.c (Fredraw_frame): Likewise.
3080 * xfaces.c (frame_or_selected_frame): Remove.
3081 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3082 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3083 (Fframe_face_alist): Use decode_live_frame.
3084 * xfns.c (check_x_frame): Likewise.
3086 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3088 * window.c (quad): New function.
3089 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3090 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3091 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3092 (Fwindow_line_height): Use it.
3093 (Fwindow_fringes): Use list3.
3094 (Fwindow_scroll_bars): Use list4.
3095 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3096 (Fwindow_combination_limit): Allow zero number of arguments.
3098 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3100 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3102 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3103 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3104 file descriptor 2 for standard error. (Bug#12805)
3106 2012-11-05 Chong Yidong <cyd@gnu.org>
3108 * process.c (wait_reading_process_output): Revert previous change.
3110 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3112 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3113 This removes code that has been obsolete since around 1990.
3114 * callproc.c (Fcall_process):
3116 * process.c (create_process):
3117 * term.c (dissociate_if_controlling_tty):
3118 Assume setsid exists.
3119 * callproc.c (child_setup): Assume setpgid exists and behaves as
3120 per POSIX.1-1988 or later.
3121 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3122 * emacs.c (shut_down_emacs):
3123 * sysdep.c (sys_suspend, init_foreground_group):
3124 Assume getpgrp behaves as per POSIX.1-1998 or later.
3125 * msdos.c (setpgrp): Remove.
3126 (tcgetpgrp, setpgid, setsid): New functions.
3127 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3128 * term.c (no_controlling_tty): Remove; unused.
3129 * w32proc.c (setpgrp): Remove.
3130 (setsid, tcgetpgrp): New functions.
3132 Simplify by assuming __fpending.
3133 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3134 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3135 Do not assume that __fpending's result fits in int.
3137 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3139 Remove EMACS_OUTQSIZE+sleep hack.
3140 * dispnew.c (update_frame_1): Remove hack for terminals slower
3141 than 2400 bps, which throttled Emacs by having it sleep.
3142 This code hasn't worked since at least 2007, when the multi-tty stuff
3143 was added, and anyway those old terminals are long dead.
3144 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3145 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3147 Fix data-loss with --version (Bug#9574).
3148 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3149 as we can't assume that emacs_strerror is initialized, and strerror
3150 is good enough here.
3151 (main): Invoke atexit earlier, to catch earlier instances of
3152 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3154 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3156 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3157 (keyDown): Remap keypad keys to X11 virtual key codes.
3159 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3161 Fix data-loss with --batch (Bug#9574).
3162 * emacs.c: Include <close-stream.h>.
3163 (close_output_streams): New function.
3164 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3165 and handles errors appropriately.
3166 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3169 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3170 The symptom is a diagnostic "GLib-WARNING **: In call to
3171 g_spawn_sync(), exit status of a child process was requested but
3172 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3173 waitpid(), so exit status can't be returned." The diagnostic
3174 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3175 The real bug is a race condition between Emacs and glib: Emacs
3176 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3177 so that glib can't find it. Work around the bug by invoking
3178 waitpid only on subprocesses that Emacs itself creates.
3179 * process.c (create_process, record_child_status_change):
3180 Don't use special value -1 in pid field, as the caller now must
3181 know the pid rather than having the callee infer it.
3182 The inference was sometimes incorrect anyway, due to another race.
3183 (create_process): Set new 'alive' member if child is created.
3184 (process_status_retrieved): New function.
3185 (record_child_status_change): Use it.
3186 Accept negative 1st argument, which means to wait for the
3187 processes that Emacs already knows about. Move special-case code
3188 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
3189 processes that have already been waited for, by testing and
3190 clearing new 'alive' member.
3191 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
3192 now does this internally.
3193 (handle_child_signal): Let record_child_status_change do all
3194 the work, since we do not want to reap all exited child processes,
3195 only the child processes that Emacs itself created.
3196 * process.h (Lisp_Process): New boolean member 'alive'.
3198 Omit duplicate definitions no longer needed with gcc -g3.
3199 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
3200 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
3201 Define only as macros. There's no longer any need to also define
3202 these symbols as enums or as constants, since we now assume
3203 gcc -g3 when debugging.
3205 2012-11-03 Eli Zaretskii <eliz@gnu.org>
3207 * lisp.mk: Adjust comments to the fact that term/internal is now
3208 loaded from loadup.el.
3210 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
3211 (msdos_fatal_signal): New function.
3212 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
3215 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
3216 for GCC versions before 4.
3217 (emacs_raise): Define to call msdos_fatal_signal.
3219 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
3220 iterator when starting in the middle of a display or overlay
3223 2012-11-03 Chong Yidong <cyd@gnu.org>
3225 * process.c (wait_reading_process_output): Clean up the last
3228 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
3230 * process.c (wait_reading_process_output): Avoid a race condition
3231 with SIGIO delivery (Bug#11536).
3233 2012-11-03 Chong Yidong <cyd@gnu.org>
3235 * buffer.c (cursor_type): Untabify docstring.
3237 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
3239 * frame.h (struct frame): Drop can_have_scroll_bars member
3240 which is meaningless for a long time. Adjust comments.

3285 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
3287 Remove pad from struct input_event.
3288 * termhooks.h (struct input_event): Remove padding field.
3290 * keyboard.c (event_to_kboard): Simplify because frame_or_window
3291 member is never cons for a long time. Adjust comment.
3292 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
3293 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
3294 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
3295 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
3297 2012-11-01 Eli Zaretskii <eliz@gnu.org>
3299 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
3301 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
3303 Fix crash when using Emacs as commit editor for git (Bug#12697).
3304 * callproc.c (setpgrp): Remove macro, as we now use setpgid
3305 and it is configured in conf_post.h.
3306 (Fcall_process): Don't invoke both setsid and setpgid; the former
3307 is enough, if it exists.
3308 * callproc.c (Fcall_process, child_setup):
3309 * process.c (create_process): Use setpgid.
3310 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
3312 * dispnew.c (init_display): Initialize the foreground group
3313 if we are running a tty display.
3314 * emacs.c (main): Do not worry about setpgrp; init_display does it now.

3322 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
3324 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
3326 2012-10-31 Martin Rudalics <rudalics@gmx.at>
3328 * minibuf.c (read_minibuf): Restore current buffer since
3329 choose_minibuf_frame calling Fset_frame_selected_window may
3330 change it (Bug#12766).

3338 * font.c (Ffont_at): If WINDOW is specified and it is not
3339 displaying the current buffer, signal an error.
3341 2012-10-29 Daniel Colascione <dancol@dancol.org>
3343 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
3344 In preparation for fixing bug#12739, move these functions from
3347 * coding.h, coding.c: ... to here, and compile them only when
3348 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
3349 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
3351 2012-10-28 Eli Zaretskii <eliz@gnu.org>
3353 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.

3368 remove last_appdefined_event (Bug#12698).
3370 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
3372 * frame.c (x_set_font): Catch internal error.
3374 2012-10-27 Eli Zaretskii <eliz@gnu.org>
3376 Avoid overflow in w32 implementation of interval timers.
3377 When possible, for ITIMER_PROF count only times the main thread
3379 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
3380 'volatile ULONGLONG' types. All the other data which was
3381 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
3382 (GetThreadTimes_Proc): New typedef.
3383 (w32_get_timer_time): New function, returns a suitable time value
3385 (timer_loop): Enter critical section when accessing ULONGLONG
3386 values of the itimer_data struct, as these accesses are no longer
3387 atomic. Call 'w32_get_timer_time' instead of 'clock'.
3388 Remove unused variable.
3389 (init_timers): Initialize s_pfn_Get_Thread_Times.
3390 (start_timer_thread): Don't assign itimer->caller_thread here.

3397 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
3398 mouse movement events if the menu bar is active. This avoids
3399 producing a busy "hour-glass" cursor by Windows if the mouse
3400 pointer is positioned over a tooltip shown for some menu item.
3402 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
3404 Don't assume process IDs fit in int.
3405 * emacs.c (shut_down_emacs) [!DOS_NT]:
3406 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
3407 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
3408 Use pid_t, not int, to store process IDs, as 'int'
3409 is not wide enough on a few platforms (e.g., AIX and IRIX).
3411 2012-10-23 Kenichi Handa <handa@gnu.org>
3413 The following change is to make face-font-rescale-alist work
3414 correctly for non-ASCII fonts.

3434 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
3436 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>

3439 * frame.c (Fmouse_position, Fmouse_pixel_position):
3440 * xdisp.c (produce_stretch_glyph):
3441 Declare local vars only when they're needed.
3442 This is clearer and avoids a warning on OpenBSD about unused vars.

3444 This is safer, and avoids OpenBSD warnings about unused vars.
3445 * keyboard.c (record_menu_key): Remove unnecessary decl.
3446 (poll_timer): Define only if POLL_FOR_INPUT is defined.
3447 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
3448 as our definition clashes with OpenBSD's.
3449 * xfaces.c (load_face_colors, check_lface_attrs)
3450 (get_lface_attributes_no_remap, get_lface_attributes)
3451 (lface_fully_specified_p, x_supports_face_attributes_p)
3452 (tty_supports_face_attributes_p, face_fontset, realize_face)
3453 (realize_x_face, realize_tty_face):
3454 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
3455 merely Lisp_Object *. This is more informative and avoids
3456 a warning on OpenBSD about accessing beyond an object's size.
3458 2012-10-20 Chong Yidong <cyd@gnu.org>
3460 * lread.c (Fload): Doc fix (Bug#12592).

3486 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
3487 (staticpro): If we run out of staticpro slots, die with an
3488 informative error instead of just calling emacs_abort.

3744 (detect_input_pending_run_timers):
3745 * process.c (wait_reading_process_output):
3746 Use unsigned for counter where wraparound-on-overflow is desired,
3747 since unsigned is guaranteed to have that behavior and signed is not.
3748 (read_char): Use ptrdiff_t for string length.
3749 (get_input_pending): Remove first argument, since it was always
3750 the same pointer-to-int (now pointer-to-boolean) &input_pending,
3751 and behave as if it had that value. Return new value of
3752 input_pending. All callers changed.
3753 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
3754 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
3756 * keymap.c (push_key_description): Omit last arg, which was always 1.
3757 All callers changed.

3775 * termopts.h (flow_control, meta_key): Remove unused decls.
3776 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
3777 Don't include termopts.h.
3779 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
3781 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
3783 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
3785 * commands.h (immediate_quit): Remove duplicate decl.
3787 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
3789 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

3792 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
3794 2012-10-09 Eli Zaretskii <eliz@gnu.org>
3796 * w32fns.c (w32_last_error): Change the return value to DWORD, to
3797 match what GetLastError returns. Explain why the function is
3800 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
3801 'is_tooltip_frame', to avoid confusion with its global namesake.
3803 2012-10-08 Daniel Colascione <dancol@dancol.org>
3805 * xdisp.c (start_hourglass): Call w32_note_current_window when
3806 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
3807 build that caused Emacs to display the hourglass cursor forever.
3809 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
3810 which is broken under remote desktop, calculate the number of
3811 colors available for a display based on the display's number of
3812 planes and number of bits per pixel per plane. (bug#10397).
3814 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
3816 * nsfont.m (Vfonts_in_cache): New variable.
3817 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
3818 are used. Add cached fonts to Vfonts_in_cache.
3819 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
3821 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
3823 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
3825 (FONT_H): Define after FRAME_H.
3826 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
3827 Update dependencies.
3829 * w32term.c: Remove leftover declaration of keyboard_codepage.
3831 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3833 * makefile.w32-in (FONT_H): Add $(FRAME_H).
3834 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
3835 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.

3842 ($(BLD)/w32menu.$(O)):
3843 ($(BLD)/w32proc.$(O)): Add w32common.h.
3845 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
3847 (x_to_w32_color): Don't modify the argument, modify a copy instead.
3849 2012-10-08 Daniel Colascione <dancol@dancol.org>
3851 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
3852 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
3853 accidental message numbering hole. Change other messages to
3856 * w32select.h (HAVE_W32SELECT): Remove.
3858 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
3859 w32common.h instead of w32heap.h.

3869 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
3870 (w32_minor_version, w32_build_number, w32_subtype):
3871 Remove duplicate definitions.
3873 * w32fns.c: Include w32common.h; include w32heap.h only in
3876 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
3877 Use `report_file_error' instead of `error' in order to better
3878 inform users of what went wrong. Increase NTGUI_UNICODE file
3879 dialog box file name length to 32k, the maximum allowed by the NT
3882 * w32common.h: New file.
3883 (ROUND_UP, ROUND_DOWN, get_page_size)
3884 (get_allocation_unit, get_processor_type, get_w32_major_version)
3885 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
3886 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
3887 (OS_NT, os_subtype, cache_system_info): Move here.
3889 * unexw32.c, unexcw.c: Include w32common.h.
3891 * emacs.c (main): Use (defined (WINDOWSNT) || defined
3892 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
3893 to call syms_of_w32select.
3895 * cygw32.h: Remove obsolete EXFUN declarations.
3897 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
3899 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
3900 of w32inevt.o from SOME_MACHINE_OBJECTS.
3902 2012-10-08 Daniel Colascione <dancol@dancol.org>
3904 * image.c: Permanent fix for JPEG compilation issue --- limit
3905 jpeglib `boolean' redefinition to Cygwin builds.
3907 2012-10-08 Eli Zaretskii <eliz@gnu.org>
3909 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
3911 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
3914 2012-10-08 Daniel Colascione <dancol@dancol.org>
3916 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
3917 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
3918 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
3919 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
3920 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
3921 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
3922 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
3923 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
3924 now a supported configuration.
3926 * Makefile.in: consolidate image variables into LIBIMAGE; add
3927 W32_OBJ and W32_LIBS. Compile new files.
3930 (_DebPrint) declare tracing facility for W32 debugging. We need
3931 to unify tracing later.
3933 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
3934 unconditional use of W32 Unicode functions. Cygwin runs only on
3935 100% Unicode operating systems.
3937 * cygw32.c: New file. Define Cygwin-specific facilities.
3938 (Fcygwin_convert_path_to_windows)
3939 (Fcygwin_convert_path_from_windows): New user functions for
3940 accessing Cygwin path-munging routines.
3942 * cygw32.h: New file.
3943 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
3944 UTF-16LE strings temporarily inside non-Lisp-visible string
3947 (w32_strerror): Just what it says on the tin.
3949 * emacs.c: Make the NS fork-then-exec code for daemon-launching
3950 also run for Cygwin; both systems have the same problem with using
3951 GUI facilities in a forked child. Also call syms_of_cygw32,
3952 syms_of_w32select in correct places.
3954 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
3955 needs fork-then-exec for daemon launching.
3957 * font.h: Include frame.h.
3959 * image.c: Use the image library cache machinery only when we're
3960 compiling for native WINDOWSNT; Cygwin can use shared libraries
3961 like any other Unixlike system.
3963 * keyboard.c: Clarify a comment regarding the input loop.
3965 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
3966 functions directly instead of trying to detect at runtime that our
3967 host operating system supports them. We make this change for two
3968 reasons: Cygwin lacks support for the multibyte character
3969 conversion functions used by the legacy menu code, and Cygwin
3970 never needs to rely on non-Unicode APIs.
3972 * unexw32.c (hinst): Declare extern.
3974 * w32.c: Change header order;
3975 (w32_strerror): Move to w32fns.c because we need it for
3976 non-WINDOWSNT builds.
3978 * w32.h: Add #error macro to make sure we don't include w32.h for
3979 Cygwin builds. Remove w32select declarations.
3981 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
3982 w32fns.c. w32console.c is WINDOWSNT-only.
3984 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
3985 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
3987 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
3988 (w32_major_version, w32_minor_version, w32_build_number)
3989 (os_subtype, sound_type): Define here
3990 (w32_defined_color): Make color parameter const for consistency
3991 with other _defined_color functions.
3992 (w32_createwindow): Unconditionally call w32_init_class instead of
3993 doing so only when hprevinst is non-NULL. Plumbing hprevinst
3994 through the code is complex and unnecessary because class
3995 registration is practically free.
3996 (w32_name_of_message): New EMACSDEBUG-only function.
3997 (Fset_message_beep): Move here
3998 (Fx_open_connection): Require that the display name for Windows be
3999 "w32" for consistency, emacsclient disambiguation, and maybe, one
4000 day, multi-window-system support.
4001 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4002 Cygwin files for W32 GUI facilities, since these clearly don't
4003 expect Cygwin names.
4004 (_DebPrint): Define.
4005 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4006 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4007 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4008 (w32_last_error): Remove.
4010 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4012 * w32heap.c (syspage_mask): Declare here.
4013 (cache_system_info): Remove.
4015 * w32inevt.c (faked_key): Define globally, not statically.
4016 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4017 (w32_console_toggle_lock_key): Move to w32fns.c.
4019 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4021 * w32proc.c (_DebPrint): Move to w32fns.c.
4022 * w32select.c: Include string.h, stdio.h for Cygwin.
4023 * w32select.h: New File.
4025 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4027 (w32_message_fd): New variable. Under Cygwin, holds the file
4028 descriptor the system used to tell us about pending thread
4031 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4032 that prevented compilation under non-WINDOWSNT systems.
4034 (w32_initialize): Open /dev/windows and assign it to
4035 w32_message_fd. Provide w32 feature.
4037 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4038 (WM_EMACS_INPUT_READY): add.
4039 (prepend_msg, w32_message_fd): Declare globally.
4042 (keyboard_handle): Use only when WINDOWSNT.
4043 (notify_msg_ready): New function. Posts a message to the main
4044 thread's message queue under CYGWIN, which wakes up the main
4045 thread from select(2) by making the /dev/windows file descriptor
4046 ready. Under WINDOWSNT, it sets an event the same way the old
4049 (post, prepend_msg): Actually call notify_msg_ready instead of
4050 setting the input event directly.
4052 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4054 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4055 but it still has blocs in it, don't return it to the system,
4056 instead of aborting. (Bug#12402)
4058 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4060 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4062 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4063 MAC_OS_X_VERSION_10_6.

4068 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4070 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4071 MAC_OS_X_VERSION_10_4.
4073 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4074 MAC_OS_X_VERSION_10_2.
4076 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4078 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4079 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4081 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4082 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4083 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4084 Remove ns_in_resize check.
4085 (ns_clear_frame_area): Remove resize handle code.
4087 * nsfns.m (ns_in_resize): Remove.
4088 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4089 Remove ns_in_resize check.
4091 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4093 Improve sys_siglist detection.
4094 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4095 defined as a macro, as is done in Solaris.
4096 (sys_siglist_entries): New macro.
4097 (save_strsignal): Use it.
4098 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4099 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4101 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4103 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4104 fullscreen/Fullscreen.
4106 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4107 tobar_height is new.
4109 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4110 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4111 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4112 (windowDidResize:): Check for correct window if old style fullscreen.
4113 Capitalize word in comment. Remove incorrect comment.
4114 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4115 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4116 error in drawing background.
4117 (toggleFullScreen:): Remove comment. Rearrange calls.
4118 Set toolbar values to zero, save old height in tobar_height.
4119 Restore tool bar height when leaving fullscreen.
4120 (canBecomeMainWindow): New function.
4122 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4124 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4126 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4128 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4130 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4131 that time stamps of directories could also be changed.
4132 Don't request the too broad GENERIC_WRITE, only the more restrictive
4133 FILE_WRITE_ATTRIBUTES access rights.
4135 * fileio.c (Fset_file_times): Special-case ignoring errors for
4136 directories only on MSDOS, not on MS-Windows.
4138 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4140 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4142 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4144 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4145 see whether CreateFile failed.
4147 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4149 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4150 to avoid similar races.
4151 * keyboard.c (pending_signals): Now bool, not int.
4153 Port timers to OpenBSD, plus check for timer failures.
4154 OpenBSD problem reported by Han Boetes.
4155 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4157 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4158 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4159 like OpenBSD, which has timer_settime but does not declare it.
4160 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4161 whether to use itimerspec-related primitives. All uses of
4162 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4164 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4166 * profiler.c (handle_profiler_signal): Fix a malloc race
4167 that caused Emacs to hang on Fedora 17 when profiling Lisp.

4176 consistent with the change in return value of 'safe_strsignal'.
4178 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4180 Prefer plain 'static' to 'static inline' (Bug#12541).
4181 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
4182 (bidi_set_sor_type, bidi_push_embedding_level)
4183 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

4190 Now 'static', not 'static inline'.
4192 Count overruns when profiling; change units to ns.
4193 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
4194 Give extra weight to samples after overruns, to attempt to count
4195 the time more accurately.
4196 (setup_cpu_timer): Change sampling interval units from ms to ns, since
4197 the underlying primitives nominally do ns.
4198 (Fprofiler_cpu_start): Document the change. Mention that
4199 the sampling intervals are only approximate.
4201 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
4203 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

4219 Fix a malloc race condition involving strsignal.
4220 A signal can arrive in the middle of a malloc, and Emacs's signal
4221 handler can invoke strsignal, which can invoke malloc, which is
4222 not portable. This race condition bug makes Emacs hang on GNU/Linux.
4223 Fix it by altering the signal handler so that it does not invoke
4225 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
4226 * process.c (status_message): Use const pointer, in case strsignal
4227 is #defined to safe_strsignal.
4228 * sysdep.c (sys_siglist, init_signals): Always define and
4229 initialize a substitute sys_siglist if the system does not define
4230 one, even if HAVE_STRSIGNAL.
4231 (safe_strsignal): Rename from strsignal. Always define,
4232 using sys_siglist. Return a const pointer.
4233 * syssignal.h (safe_strsignal): New decl.
4234 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
4236 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4238 * w32proc.c (timer_loop): Fix code that waits for timer
4239 expiration, to avoid high CPU usage.
4241 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
4243 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
4244 (sweep_weak_table): Remove redundant prototypes.
4246 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
4248 * emacs.c: Move the inclusion of TERM_HEADER after including
4249 windows.h on WINDOWSNT. This avoids compilation problems with
4252 2012-10-01 Eli Zaretskii <eliz@gnu.org>
4254 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
4255 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
4256 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
4257 as the previous version used 'void *'.
4259 * ralloc.c (ROUNDUP): Fix last change.
4260 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
4263 * w32proc.c <disable_itimers>: New static flag.
4264 (init_timers): Initialize it to zero, after creating the critical
4265 sections used by the timer threads.
4266 (term_timers): Set to 1 before deleting the critical sections.
4267 (getitimer, setitimer): If disable_itimers is non-zero, return an
4268 error indication without doing anything. Reported by Fabrice
4269 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
4270 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
4272 [!HAVE_SETITIMER]: Behave as the previous version that didn't
4275 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
4276 term_ntproc after all the other bookkeeping, to get timers working
4277 as long as possible.
4279 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
4281 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
4282 Suggested by Juri Linkov in
4283 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
4285 Prefer plain 'static' to 'static inline' (Bug#12541).
4286 With static functions, modern compilers inline pretty well by
4287 themselves; advice from programmers often hurts as much as it helps.
4288 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
4289 this change shrinks the text size of the Emacs executable by 1.1%
4290 without affecting CPU significantly in my benchmark.

4371 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
4373 Revert the FOLLOW-SYMLINKS change for file-attributes.
4374 Doing it right would require several changes to Tramp, and there's
4375 not enough time to get that tested before the freeze today.
4376 * dired.c (directory_files_internal, Ffile_attributes):

4413 * w32.c (init_environment, get_emacs_configuration): Support AMD64
4415 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
4416 compatibility with x64.
4418 * vm-limit.c (lim_data): Now size_t.
4419 (check_memory_limits): Adjust prototypes of real_morecore and
4420 __morecore to receive argument of type ptrdiff_t. Use size_t for
4421 five_percent and data_size.
4423 * unexw32.c: Use DWORD_PTR instead of DWORD for file-scope
4424 variables, for compatibility with x64.

4447 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows

4569 HAVE_TIMER_SETTIME is defined.
4571 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
4573 Profiler improvements: more-accurate timers, overflow checks.
4574 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
4575 signal.h, setjmp.h. Include systime.h instead.
4576 (saturated_add): New function.
4577 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

4583 All uses changed to store the new value.
4584 (handle_profiler_signal): Rename from sigprof_handler_1,
4585 for consistency with other handlers. Do not check whether
4586 cpu_log is a hash-table if garbage collecting, since it
4587 doesn't matter in that case.
4588 (deliver_profiler_signal): Rename from sigprof_handler,
4589 for consistency with other handlers.
4590 (setup_cpu_timer): New function, with much of what used to be in
4591 Fprofiler_cpu_start. Check for out-of-range argument.
4592 Prefer timer_settime if available, and prefer
4593 thread cputime clocks, then process cputime clocks, then
4594 monotonic clocks, to the old realtime clock. Use make_timeval
4595 to round more-correctly when falling back to setitimer.
4596 (Fprofiler_cpu_start): Use it.
4597 (Fprofiler_cpu_stop): Prefer timer_settime if available.
4598 Don't assume that passing NULL as the 2nd argument of setitimer
4599 is the same as passing a pointer to all-zero storage.
4600 Ignore SIGPROF afterwards.
4601 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
4602 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
4603 non-fatal signal handlers. Ignore SIGPROF on startup.
4604 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
4605 in profiler.c, since sysdep.c now uses it.
4607 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

4627 (Frun_hook_with_args_until_failure): Doc fixes.
4629 2012-09-28 Eli Zaretskii <eliz@gnu.org>
4631 * xdisp.c (syms_of_xdisp) <Qredisplay_internal>: Rename from
4632 Qautomatic_redisplay and change the symbol name. All users changed.

4645 * Makefile.in (LIB_TIMER_TIME): New macro.
4647 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
4648 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
4651 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
4653 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.

4659 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
4661 * character.h (MAYBE_UNIFY_CHAR): Remove.
4662 * charset.c, charset.h (maybe_unify_char): Now static.
4663 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
4664 Since this stuff is now private to charset.c, there's no need for
4665 a public macro and no need to inline by hand.

4694 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4696 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
4698 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
4700 Prefer POSIX timers if available.
4701 They avoid a race if the timer is too close to the current time.
4702 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
4703 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
4704 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
4706 2012-09-25 Eli Zaretskii <eliz@gnu.org>

4711 STRING_CHAR_ADVANCE.
4713 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
4715 Move Vlibrary_cache to emacs.c and reset before dumping.
4717 * lisp.h (reset_image_types): Declare.

4720 * image.c (reset_image_types): New function.
4722 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

4729 * w32.h (Vlibrary_cache): Do not declare.
4731 2012-09-25 Eli Zaretskii <eliz@gnu.org>
4733 * w32proc.c (sys_signal): Handle all signals defined by the
4734 MS-Windows runtime, not just SIGCHLD. Actually install the signal
4735 handlers for signals supported by Windows. Don't override
4736 term_ntproc as the handler for SIGABRT.
4737 (sigaction): Rewrite to call sys_signal instead of duplicating its
4739 (sys_kill): Improve commentary.
4741 * w32.c (term_ntproc): Accept (and ignore) one argument, for
4742 consistency with a signature of a signal handler. All callers
4744 (init_ntproc): Accept an argument DUMPING. If dumping, don't
4745 install term_ntproc as a signal handler for SIGABRT, as that
4746 should be done by the dumped Emacs.
4748 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
4750 * w32select.c (term_w32select): Protect against repeated
4751 invocation by setting clipboard_owner to NULL after calling

4755 and term_ntproc to their modified signatures.
4757 * character.c (char_string, string_char): Remove calls to
4758 MAYBE_UNIFY_CHAR. See the discussion starting at

4762 2012-09-25 Chong Yidong <cyd@gnu.org>
4764 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
4766 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
4768 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
4769 when encountering an unknown bytecode.
4771 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
4773 image.c, indent.c: Use bool for booleans.
4774 * dispextern.h (struct image_type): Members valid_p, load, init
4775 now return bool, not int. All uses changed.
4776 * image.c: Omit unnecessary static decls.
4777 (x_create_bitmap_mask, x_build_heuristic_mask):
4778 Return void, not int, since callers don't care about the return value.

4811 * chartab.c (Fset_char_table_default): Obsolete function removed.
4813 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4815 Move pid_t related decls out of lisp.h.
4816 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
4817 (interruptible_wait_for_termination):
4818 Move these decls from lisp.h to syswait.h, since they use pid_t.
4819 Needed on FreeBSD; see Herbert J. Skuhra in
4820 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
4821 * callproc.c: Include syswait.h.

4839 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):

4841 Use bool for boolean.
4842 * gtkutil.c (xg_update_frame_menubar):
4843 * xmenu.c (update_frame_menubar):
4844 Return void, not int, since caller ignores return value.

4848 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4850 * makefile.w32-in (BLOCKINPUT_H): Remove.

4867 2012-09-23 Eli Zaretskii <eliz@gnu.org>
4869 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
4870 fatal_error_backtrace.
4872 * w32proc.c (sys_kill): Undo last change: don't do anything when
4873 invoked to deliver SIGABRT to our own process. This is now
4874 handled by emacs_raise.
4876 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
4878 * w32term.c (w32_read_socket): Remove leftover reference to
4879 interrupt_input_pending.
4881 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4883 Do not use SA_NODEFER.
4884 Problem reported by Dani Moncayo in
4885 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
4887 * sysdep.c (emacs_abort): Do not reset signal handler.
4888 * emacs.c (terminate_due_to_signal): Reset signal handler here.
4889 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
4890 wanted even on POSIXish hosts, and it doesn't work on Windows.
4892 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
4894 * xterm.c (x_term_init): Call fixup_locale before and after calling
4895 gtk_init (Bug#12392).
4897 2012-09-23 Chong Yidong <cyd@gnu.org>
4899 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
4900 Vdynamic_library_alist.
4902 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
4903 (Fgnutls_available_p): Caller changed.
4905 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
4906 (Flibxml_parse_xml_region): Likewise.
4908 * dispextern.h (struct image_type): Remove arg from init function.
4910 * image.c (Finit_image_library, lookup_image_type)
4911 (define_image_type): Remove now-unneeded second arg.
4912 (init_xpm_functions, init_png_functions, init_jpeg_functions)
4913 (init_tiff_functions, init_gif_functions, init_svg_functions):
4914 Arglist and w32_delayed_load calling convention changed.
4915 (gs_type): Remove init_gs_functions; there is no such function.
4916 (valid_image_p, make_image): Fix caller to lookup_image_type.
4918 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
4920 Simplify and avoid signal-handling races (Bug#12471).
4922 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
4923 Avoid recursive loop if there's a fatal error in the function itself.
4924 * atimer.c (pending_atimers):
4925 * blockinput.h: Don't include "atimer.h"; no longer needed.
4926 (interrupt_input_pending): Remove. All uses removed.
4927 pending_signals now counts both atimers and ordinary interrupts.
4928 This is less racy than having three separate pending-signal flags.
4929 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
4931 Rename from their upper-case counterparts BLOCK_INPUT,
4932 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
4933 INPUT_BLOCKED_P, and turn into functions. All uses changed.
4934 This makes it easier to access volatile variables more accurately.
4935 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
4936 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
4937 that's more reliable if the code is buggy and sets
4938 interrupt_input_blocked to a negative value. All uses changed.
4939 * atimer.c (deliver_alarm_signal):
4940 Remove. No need to deliver this to the parent; any thread can
4941 handle this signal now. All uses replaced by underlying handler.
4942 * atimer.c (turn_on_atimers):
4943 * dispnew.c (handle_window_change_signal):
4944 * emacs.c (handle_danger_signal):
4945 * keyboard.c (kbd_buffer_get_event):
4946 Don't reestablish signal handler; not needed with sigaction.
4947 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
4949 Rework to avoid unnecessary accesses to volatile variables.
4950 (UNBLOCK_INPUT_TO): Now a function.
4951 (totally_unblock_input, unblock_input): New decls.
4952 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
4953 (init_data): Remove. Necessary stuff now done in init_signal.
4954 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
4955 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
4956 (fatal_error_code): Remove; no longer needed.
4957 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
4958 it doesn't always backtrace. All uses changed. No need to reset
4959 signal to default, since sigaction and/or die does that for us now.
4960 Use emacs_raise (FOO), not kill (getpid (), FOO).
4961 (main): Check more-accurately whether we're dumping.
4962 Move fatal-error setup to sysdep.c
4963 * floatfns.c: Do not include "syssignal.h"; no longer needed.
4964 * gtkutil.c (xg_get_file_name, xg_get_font):
4965 Remove no-longer-needed signal-mask manipulation.
4966 * keyboard.c, process.c (POLL_FOR_INPUT):
4967 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
4968 * keyboard.c (read_avail_input): Remove.
4969 All uses replaced by gobble_input.
4970 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
4971 (kbd_buffer_store_event_hold, gobble_input):
4972 (record_asynch_buffer_change) [USABLE_SIGIO]:
4973 (store_user_signal_events):
4974 No need to mess with signal mask.
4975 (gobble_input): If blocking input and there are terminals, simply
4976 set pending_signals to 1 and return. All hooks changed to not
4977 worry about whether input is blocked.
4978 (process_pending_signals): Clear pending_signals before processing
4979 them, in case a signal comes in while we're processing.
4980 By convention callers now test pending_signals before calling us.
4981 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
4982 New functions, to support changes to blockinput.h.
4983 (handle_input_available_signal): Now extern.
4984 (reinvoke_input_signal): Remove. All uses replaced by
4986 (quit_count): Now volatile, since a signal handler uses it.
4987 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
4988 All callers changed. Block SIGINT only if not already blocked.
4989 Clear sigmask reliably, even if Fsignal returns, which it can.
4990 Omit unnecessary accesses to volatile var.
4991 (quit_throw_to_read_char): No need to restore sigmask.
4992 * keyboard.c (gobble_input, handle_user_signal):
4993 * process.c (wait_reading_process_output):
4994 Call signal-handling code rather than killing ourselves.
4995 * lisp.h: Include <float.h>, for...
4996 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
4997 (pending_signals): Now volatile.
4998 (syms_of_data): Now const if IEEE floating point.
4999 (handle_input_available_signal) [USABLE_SIGIO]:
5000 (terminate_due_to_signal, record_child_status_change): New decls.
5001 * process.c (create_process): Avoid disaster if memory is exhausted
5002 while we're processing a vfork, by tightening the critical section
5004 (send_process_frame, process_sent_to, handle_pipe_signal)
5005 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5007 (send_process): No need for setjmp/longjmp any more, since the
5008 SIGPIPE stuff is now gone. Instead, report an error if errno
5010 (record_child_status_change): Now extern. PID and W are now args.
5011 Return void, not bool. All callers changed.
5012 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5013 Remove. All uses removed. This bug should be fixed now in a
5015 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5016 and record the child status change directly. This avoids the
5017 need to futz with the signal mask.
5018 (process_fatal_action): Move here from emacs.c.
5019 (emacs_sigaction_flags): New function, containing
5020 much of what used to be in emacs_sigaction_init.
5021 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5022 caught by emacs, to make races less likely.
5023 (deliver_process_signal): Rename from handle_on_main_thread.
5025 (BACKTRACE_LIMIT_MAX): Now at top level.
5026 (thread_backtrace_buffer, threadback_backtrace_pointers):
5028 (deliver_thread_signal, deliver_fatal_thread_signal):
5029 New functions, for more-accurate delivery of thread-specific signals.
5030 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5031 (deliver_arith_signal): Handle in this thread, not
5032 in the main thread, since it's triggered by this thread.
5033 (maybe_fatal_sig): New function.
5034 (init_signals): New arg DUMPING so that we can be more accurate
5035 about whether we're dumping. Caller changed.
5036 Treat thread-specific signals differently from process-general signals.
5037 Block all signals while handling fatal error; that's safer.
5038 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5040 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5041 Ignore SIGPIPE unless batch.
5042 (emacs_backtrace): Output backtrace for the appropriate thread,
5043 which is not necessarily the main thread.
5044 * syssignal.h: Include <stdbool.h>.
5045 (emacs_raise): New macro.
5046 * xterm.c (x_connection_signal): Remove; no longer needed
5047 now that we use sigaction.
5048 (x_connection_closed): No need to mess with sigmask now.
5049 (x_initialize): No need to reset SIGPIPE handler here, since
5050 init_signals does this for us now.
5052 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5054 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5055 background rect may be larger (Bug#12245).
5057 2012-09-23 Chong Yidong <cyd@gnu.org>
5059 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5061 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5063 * .gdbinit: Just stop at fatal_error_backtrace.
5064 See Stefan Monnier's request in
5065 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5066 Remove no-longer-used query of system type.
5068 2012-09-22 Chong Yidong <cyd@gnu.org>
5070 * search.c (Freplace_match): Doc fix (Bug#12325).
5072 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5074 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5075 (Fline_end_position): Doc fix.
5077 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5079 2012-09-22 Chong Yidong <cyd@gnu.org>
5081 * dispextern.h (struct image_type): Add new slot, storing a type
5082 initialization function.
5084 * image.c (define_image_type): Call the image initializer function
5085 if it is defined. Arguments and return value changed.
5086 (valid_image_p, make_image): Callers changed.
5087 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5088 (gif_type, imagemagick_type, svg_type, gs_type):
5089 Add initialization functions.
5090 (Finit_image_library): Call lookup_image_type.
5091 (CHECK_LIB_AVAILABLE): Macro deleted.
5092 (lookup_image_type): Call define_image_type here, rather than via
5093 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5094 (syms_of_image): Move define_image_type calls for xbm_type and
5095 pbm_type to lookup_image_type.
5097 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5099 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5100 'idle_timers' from here ...
5101 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5102 lists, to avoid infloops when the timer does something stupid,
5103 like reinvoke itself with the same or smaller time-out.
5106 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5108 * window.c (Fsplit_window_internal): Handle only Qt value of
5109 Vwindow_combination_limit separately.
5110 (Qtemp_buffer_resize): New symbol.
5111 (Vwindow_combination_limit): New default value.
5114 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5116 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5117 the new overlay string. (Bug#10159)
5119 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5121 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5122 or that fprintf is async-signal-safe. POSIX doesn't require
5125 2012-09-22 Chong Yidong <cyd@gnu.org>
5127 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5130 2012-09-22 Kenichi Handa <handa@gnu.org>
5132 * composite.c (composition_reseat_it): Handle the case that a
5133 grapheme cluster is not covered by a single font (Bug#12352).
5135 2012-09-21 Chong Yidong <cyd@gnu.org>
5137 * image.c (define_image_type): Avoid adding duplicate types to
5138 image_types (Bug#12463). Suggested by Jörg Walter.
5140 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5142 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5143 (print_load_command_name): Add case LC_DATA_IN_CODE.
5144 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5146 2012-09-21 Glenn Morris <rgm@gnu.org>
5148 * eval.c (Frun_hook_with_args_until_success)
5149 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5151 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5153 * fileio.c (Ffile_selinux_context): Only call freecon when
5154 lgetfilecon succeeded.
5155 (Fset_file_selinux_context): Likewise. (Bug#12444)
5157 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5159 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5160 reordering, locate the cursor by calling set_cursor_from_row; if
5161 that fails, clear the desired glyph matrix before returning a
5162 failure indication to the caller. Fixes leaving garbled display
5163 when fast scrolling with a down-key. (Bug#12403)
5164 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5165 scrolling through multibyte text.
5167 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5169 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5170 calling mark_vectorlike since that's the one that marks the window.
5171 (mark_discard_killed_buffers): Mark the final cdr.
5172 * window.h (struct window): Move prev/next_buffers to the
5173 non-standard fields.
5174 * window.c (make_window): Initialize prev/next_buffers manually.
5176 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5178 Omit unused arg EXPECTED from socket hooks.
5179 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
5180 * nsterm.m (ns_term_init):
5181 * termhooks.h (struct terminal.read_socket_hook):
5182 * w32inevt.c (w32_console_read_socket):
5183 * w32term.c (w32_read_socket):
5184 * xterm.c (XTread_socket):
5185 Omit unused arg EXPECTED. All callers changed.
5186 (store_user_signal_events): Return void, not int, since callers no
5187 longer care about the return value. All uses changed.
5189 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
5191 * w32gui.h (XParseGeometry): Do not declare.
5193 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
5195 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
5196 Ignore 'expected'. See Eli Zaretskii in
5197 <http://bugs.gnu.org/12471#8> (last line).
5199 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
5200 (XParseGeometry): Now static. Substitute extremal values for
5201 values that are out of range.
5203 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
5205 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
5207 * nsfns.m (XParseGeometry): Remove.
5208 (Fx_create_frame): Call x_set_offset to correctly interpret
5209 top_pos in geometry.
5211 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
5212 (Fx_parse_geometry): If there is a space in string, call
5213 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
5215 2012-09-17 Eli Zaretskii <eliz@gnu.org>
5217 * search.c (scan_buffer): Use character positions in calls to
5218 region_cache_forward and region_cache_backward, not byte
5219 positions. (Bug#12196)
5221 * w32term.c (w32_read_socket): Set pending_signals to 1, like
5222 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
5224 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
5225 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
5226 emacs_blocked_malloc, now deleted.
5228 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
5230 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
5231 The workaround was for improving performance on Solaris 2.4, but
5232 is getting in the way now. Emacs will still work if someone is
5233 still running Solaris 2.4 in a museum somewhere; Sun dropped
5234 support for Solaris 2.4 in 2003.
5235 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
5236 * process.c (create_process) [HAVE_WORKING_VFORK]:
5237 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
5238 since Emacs no longer uses vfork on that platform.
5240 2012-09-17 Glenn Morris <rgm@gnu.org>
5242 * emacs.c: Use COPYRIGHT.
5244 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
5246 Remove configure's --without-sync-input option (Bug#12450).
5247 When auditing signal-handling in preparation for cleaning it up,
5248 I found that SYNC_INPUT has race conditions and would be a real
5249 pain to fix. Since it's an undocumented and deprecated
5250 configure-time option, now seems like a good time to remove it.
5251 Also see <http://bugs.gnu.org/11080#16>.
5252 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
5253 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
5254 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5255 (malloc_hysteresis):
5256 (check_depth) [XMALLOC_OVERRUN_CHECK]:
5257 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
5258 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
5259 (dont_register_blocks, bytes_used_when_reconsidered)
5260 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
5261 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
5262 [!SYSTEM_MALLOC && !SYNC_INPUT]:
5263 Remove. All uses removed.
5264 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
5265 implementation, one that depends on whether the new macro
5266 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
5268 * atimer.c (run_timers, handle_alarm_signal):
5269 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
5270 (handle_async_input, process_pending_signals)
5271 (handle_input_available_signal, init_keyboard):
5272 * nsterm.m (ns_read_socket):
5273 * process.c (wait_reading_process_output):
5274 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
5275 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
5277 * xterm.c (XTread_socket):
5279 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
5280 * eval.c (handling_signal): Remove. All uses removed.
5281 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
5282 All uses replaced with the SYNC_INPUT version.
5283 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
5285 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5288 * font.c (Ffont_shape_gstring): Remove unused local.
5290 2012-09-16 Glenn Morris <rgm@gnu.org>
5292 * Makefile.in (clean): No longer run nextstep's clean.
5294 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
5296 (ns-app): Move here from ns.mk, and simplify.
5297 (clean): Simplify nextstep entry.
5298 * ns.mk: Remove file.
5300 2012-09-17 Kenichi Handa <handa@gnu.org>
5302 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
5303 not covert the last few charactes.
5305 2012-09-16 Kenichi Handa <handa@gnu.org>
5307 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
5308 here, but just check the validity of glyphs in the glyph-string.
5310 2012-09-16 Martin Rudalics <rudalics@gmx.at>
5312 * window.c (Fwindow_parameter, Fset_window_parameter):
5313 Accept any window as argument (Bug#12452).
5315 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
5317 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
5318 to ns_term_init to avoid memory leak.
5320 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
5321 explicit retain/release.
5322 (ns_term_init): Only allow one display. Initialize outerpool and
5325 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5327 Port _setjmp fix to POSIXish hosts as well as Microsoft.
5328 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
5329 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
5330 the Microsoft problem in a different way, by altering ../nt/config.nt.
5332 2012-09-15 Eli Zaretskii <eliz@gnu.org>
5347 * w16select.c: Remove inclusion of setjmp.h, as it is now included
5348 by lisp.h. This completes removal of setjmp.h inclusion
5349 erroneously announced in the previous commit. (Bug#12446)
5351 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
5354 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
5355 not defined as a macro. The latter happens on MS-Windows.
5358 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
5360 Port better to POSIX hosts lacking _setjmp (Bug#12446).
5361 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
5362 Some instances of '#include <setjmp.h>' removed, if the
5363 only reason for the instance was because "lisp.h" was included.
5364 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
5365 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
5366 and _longjmp with the new symbols. Emacs already uses _setjmp if
5367 available, so this change affects only POSIXish hosts that have
5368 sigsetjmp but not _setjmp, such as some versions of Solaris and
5369 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
5370 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
5371 (png_load_body) [HAVE_PNG]:
5372 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
5373 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
5374 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
5375 since PNG requires jmp_buf. This is the only exception to the
5376 general rule that we now use sys_setjmp and sys_longjmp.
5377 This exception is OK since this code does not change the signal
5378 mask or longjmp out of a signal handler.
5380 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
5382 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
5383 Include "syssignal.h", for 'main_thread'.
5385 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
5387 Avoid out-of-range marker position (Bug#12426).
5388 * insdel.c (replace_range, replace_range_2):
5389 Adjust markers before overlays, as suggested by comments.
5390 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
5391 Remove redundant check before calling offset_intervals.
5393 2012-09-14 Martin Rudalics <rudalics@gmx.at>
5395 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
5396 current buffer (Bug#12387).
5398 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
5400 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
5402 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5404 Use a more backwards-compatible timer format (Bug#12430).
5405 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
5406 vector element, not from the 4th, since PSECS is now at the end.
5407 (Fcurrent_idle_time): Doc fix.
5409 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
5411 Function to mark objects and remove killed buffers at once.
5412 * alloc.c (discard_killed_buffers): Rename to ...
5413 (mark_discard_killed buffers) ... new name. Add marking
5414 of remaining objects. Fix comment. Adjust users.
5415 (mark_object): Do not touch frame buffer lists here.
5416 * frame.c (delete_frame): Reset frame buffer lists here.
5418 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
5420 Better workaround for GNOME bug when --enable-gcc-warnings.
5421 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
5422 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
5423 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
5425 Simplify SIGIO usage (Bug#12408).
5426 The code that dealt with SIGIO was crufty and confusing, e.g., it
5427 played tricks like "#undef SIGIO" but these tricks were not used
5428 consistently. Simplify mostly by not #undeffing standard symbols,
5429 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
5430 or not as we please) rather than "defined SIGIO" (standard symbol
5431 that we probably shouldn't #undef).
5432 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
5433 Modules that need it can include it.
5434 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
5435 * dispextern.h (ignore_sigio): New decl.
5436 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
5437 unconditionally, since it's now a no-op if !USABLE_SIGIO.
5438 * emacs.c (shut_down_emacs):
5439 * keyboard.c (kbd_buffer_store_event_hold):
5440 Use ignore_sigio rather than invoking 'signal' directly.
5441 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
5443 (FIONREAD, SIGIO): Do not #undef.
5444 (tty_read_avail_input): Use #error rather than a syntax error.
5445 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
5446 for I_PIPE, used by SETUP_SLAVE_PTY.
5447 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
5448 * sysdep.c (croak): Remove; no longer needed. This bit of
5449 temporary code, with Fred N. Fish's comment that it's temporary,
5450 has been in Emacs since at least 1992!
5451 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
5452 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
5453 * syssignal.h (croak): Remove decl.
5454 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
5455 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
5456 now that we're termios-only.
5457 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
5458 * term.c (dissociate_if_controlling_tty): Use #error rather than
5461 Work around GCC and GNOME bugs when --enable-gcc-warnings.
5462 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
5463 to work around GNOME bug 683906.
5464 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
5465 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
5466 This works around GCC bug 54561.
5468 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5470 More fixes for 'volatile' and setjmp/longjmp.
5471 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
5472 * image.c (struct png_load_context) [HAVE_PNG]: New type.
5473 (png_load_body) [HAVE_PNG]:
5474 (jpeg_load_body) [HAVE_JPEG]:
5475 New function, with most of the old parent function's body.
5476 (png_load) [HAVE_PNG]:
5477 (jpeg_load) [HAVE_JPEG]:
5478 Invoke the new function, to avoid longjmp munging our locals.
5479 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
5480 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
5481 longjmp is passed 2, as the C standard doesn't guarantee this.
5482 Instead, store the failure code into mgr->failure_code.
5484 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5486 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
5487 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
5488 (syms_of_keyboard): Remove support for unread-command-char.
5490 2012-09-12 Eli Zaretskii <eliz@gnu.org>
5492 * w32proc.c (sys_kill): If PID is our process ID and the signal is
5493 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
5494 violation. (Bug#12426)
5496 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
5498 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
5500 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
5502 * eval.c: Add `inhibit-debugger'.
5503 (Qinhibit_debugger): New symbol.
5504 (call_debugger): Bind it instead of Qdebug_on_error.
5505 (maybe_call_debugger): Test Vinhibit_debugger.
5506 (syms_of_eval): Define inhibit-debugger.
5507 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
5508 (syms_of_xdisp): Remove inhibit-debug-on-message.
5510 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5512 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
5513 If a nonvolatile local variable is written before a _longjmp to
5514 the frame containing the variable, and is read after the _longjmp,
5515 the value read is indeterminate. Some local variables of type
5516 'struct handler' and 'struct catchtag' are used in this way, so
5517 mark each of their slots as volatile if the slot can be set before
5518 _longjmp and read afterwards.
5519 * lisp.h (struct handler): var and chosen_clause are now volatile.
5520 (struct catchtag): val, next, and pdlcount are now volatile.
5522 * bidi.c (bidi_push_it, bidi_pop_it):
5523 * fns.c (copy_hash_table):
5524 * image.c (define_image_type):
5525 * keyboard.c (kbd_buffer_store_event_hold):
5526 * process.c (Fprocess_send_eof):
5527 * xfaces.c (x_create_gc) [HAVE_NS]:
5528 * xgselect.c (xg_select):
5529 Prefer assignment to memcpy when either will do.
5531 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
5532 Use pointer-to-a-pointer to simplify and avoid a NILP check each
5533 time an item is removed. No need to mark this function 'inline';
5534 the compiler knows better than we do.
5536 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
5538 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
5539 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
5540 to change_frame_size (Bug#12388).
5541 (windowDidResize:): Pass YES to updateFrameSize.
5543 * nsterm.h: Add delay parameter to updateFrameSize.
5545 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5547 Discard killed buffers from deleted window and frame objects.
5548 This reduces an amount of references to killed buffers and
5549 helps GC to reclaim them faster.
5550 * alloc.c (discard_killed_buffers): New function.
5551 (mark_object): Use it for deleted windows and frames.
5552 (mark_object): If symbol's value is set up for a killed buffer
5553 or deleted frame, restore its global binding.
5554 * data.c (swap_in_global_binding): Add GC notice.
5555 (swap_in_symval_forwarding): Use convenient set_blv_where.
5556 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
5557 * window.h: ... to here.
5559 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
5561 Convenient macro to check whether the buffer is live.
5562 * buffer.h (BUFFER_LIVE_P): New macro.
5563 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
5564 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
5566 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5568 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
5569 composition cases (Bug#12364).
5571 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
5572 overhang of succeeding glyphs overlapping box cursor.
5574 * w32term.c (x_draw_glyph_string): Likewise.
5576 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
5578 Simplify, document, and port floating-point (Bug#12381).
5579 The porting part of this patch fixes bugs on non-IEEE platforms
5580 with frexp, ldexp, logb.
5581 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
5583 * floatfns.c: Simplify discussion of functions that Emacs doesn't
5584 support, by removing commented-out code and briefly listing the
5585 C89 functions excluded. The commented-out stuff was confusing
5586 maintenance, e.g., we thought we needed cbrt but it was commented out.
5587 (logb): Remove decl; no longer needed.
5588 (isfinite): New macro, if not already supplied.
5589 (isnan): Don't replace any existing macro.
5590 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
5591 are present on all C89 platforms.
5592 (Ffrexp): Do not special-case zero, as frexp does the right thing
5594 (Flogb): Do not use logb, as it doesn't have the desired meaning
5595 on hosts that use non-base-2 floating point. Instead, stick with
5596 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
5597 frexp, to avoid getting an unspecified result.
5599 * xdisp.c (Qinhibit_debug_on_message): Now static.
5601 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
5603 * nsterm.m (ns_update_begin): Set clip path to whole view by using
5604 NSBezierPath (Bug#12131).
5606 2012-09-10 Chong Yidong <cyd@gnu.org>
5608 * fns.c (Fdelq, Fdelete): Doc fix.
5610 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
5612 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
5613 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
5615 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
5617 * lisp.h (make_lisp_ptr): New macro to replace XSET.
5618 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
5621 2012-09-09 Eli Zaretskii <eliz@gnu.org>
5623 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
5624 left fringe if the window has a left margin. This avoids leaving
5625 traces of the cursor because its leftmost pixel is not drawn over.
5627 * dispnew.c (update_window_line): When the left margin area of a
5628 screen line is updated, set the redraw_fringe_bitmaps_p flag of
5629 that screen line. (Bug#12277)
5631 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
5633 Assume C89 or later for math functions (Bug#12381).
5634 This simplifies the code, and makes it a bit smaller and faster,
5635 and (most important) makes it easier to clean up signal handling
5636 since we can stop worring about floating-point exceptions in
5637 library code. That was a problem before C89, but the problem
5638 went away many years ago on all practical Emacs targets.
5639 * data.c, image.c, lread.c, print.c:
5640 Don't include <math.h>; no longer needed.
5641 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
5642 might be autoconfigured, as that never happens.
5644 * doprnt.c (DBL_MAX_10_EXP):
5645 * print.c (DBL_DIG):
5646 Remove. C89 or later always defines these.
5647 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
5648 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
5649 (arith_error, domain_error, domain_error2):
5650 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
5651 no longer needed -- we simply return what C returns. All uses removed.
5652 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
5654 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
5655 Remove. All uses expanded, as these macros are no longer used
5656 more than once and are now more trouble than they're worth.
5657 (Ftan): Use tan, not sin / cos.
5658 (Flogb): Assume C89 frexp.
5659 (fmod_float): Assume C89 fmod.
5660 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
5661 (init_floatfns): Remove. All uses removed.
5663 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5665 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
5666 compositeToPoint for OSX < 10.6 (Bug#12390).
5668 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
5670 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
5671 This produces more-accurate results.
5673 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5675 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
5676 changes (Bug#12088).
5678 2012-09-08 Chong Yidong <cyd@gnu.org>
5680 * syntax.c (Fstring_to_syntax): Doc fix.
5682 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
5684 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
5685 in the internal border.
5686 (x_set_window_size): Remove static variables and their usage.
5687 (ns_redraw_scroll_bars): Fix NSTRACE arg.
5688 (ns_after_update_window_line, ns_draw_fringe_bitmap):
5689 Remove fringe/internal border adjustment (Bug#11052).
5690 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
5691 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
5692 (ns_fix_rect_ibw): Remove.
5693 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
5694 (ns_dumpglyphs_box_or_relief): Ditto.
5695 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
5697 (ns_dumpglyphs_image): Ditto.
5698 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
5700 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
5701 their usage. Add fringe_extended_p and its use as in other terms.
5702 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
5703 scroll bar was removed.
5704 (updateFrameSize): New function.
5705 (windowDidResize): Move code to updateFrameSize and call it.
5707 * nsterm.h (EmacsView): Add updateFrameSize.
5709 2012-09-07 Chong Yidong <cyd@gnu.org>
5711 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
5713 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
5715 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5717 More signal-handler cleanup (Bug#12327).
5718 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
5719 Problem introduced when merging patches. Noted by Eli Zaretskii in
5720 <http://bugs.gnu.org/12327#67>.
5721 * floatfns.c: Comment fix.
5722 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
5723 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
5724 and anyway the declaration is harmless even if SIGDANGER is not defined.
5725 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
5726 defined BROKEN_FIONREAD). systty.h formerly did this, but other
5727 source files not surprisingly expected syssignal.h to define, or
5728 not define, SIGIO, and it's cleaner to do it that way, for consistency.
5729 Include <sys/ioctl.h>, for FIONREAD.
5730 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
5731 This eliminates a problem whereby other files mysteriously had
5732 to include "syssignal.h" before including "systty.h" if they
5733 wanted to use "#ifdef SIGIO".
5735 2012-09-07 Eli Zaretskii <eliz@gnu.org>
5737 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
5739 * w32.c (sigemptyset): Empty the set.
5740 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
5742 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
5744 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
5746 * alloc.c (mark_buffer): Revert unsafe marking optimization.
5747 (mark_object): Likewise for frame objects.
5749 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
5751 * syssignal.h (handle_on_main_thread): Always declare,
5752 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
5753 This ports to platforms without HAVE_PTHREAD.
5755 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5757 Signal-handler cleanup (Bug#12327).
5758 Emacs's signal handlers were written in the old 4.2BSD style with
5759 sigblock and sigmask and so forth, and this led to some
5760 inefficiencies and confusion. Rewrite these to use
5761 pthread_sigmask etc. without copying signal sets around. Also,
5762 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
5763 'signal', and instead use functions that do not attempt to take
5764 over the system name space. This patch causes Emacs's text
5765 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
5766 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
5767 Do not include <signal.h> or "syssignal.h", as these
5768 modules do not use signals.
5769 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
5770 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
5771 Do not include <signal.h>, as "syssignal.h" does that for us now.
5772 * atimer.c (sigmask_atimers): New function.
5773 (block_atimers, unblock_atimers): New functions,
5774 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
5776 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
5777 no longer needed here.
5778 * emacs.c (main): Inspect existing signal handler with sigaction,
5779 so that there's no need to block and unblock SIGHUP.
5780 * sysdep.c (struct save_signal): New member 'action', replacing
5781 old member 'handler'.
5782 (save_signal_handlers, restore_signal_handlers):
5783 Use sigaction instead of 'signal' to save and restore.
5784 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
5785 New function. All users of 'signal' modified to use set_sighandler
5786 if they're writeonly, and to use sys_signal if they're read+write.
5787 (emacs_sigaction_init, forwarded_signal): New functions.
5788 (sys_signal): Remove. All uses replaced by calls to sigaction
5789 and emacs_sigaction_init, or by direct calls to 'signal'.
5790 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
5791 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
5792 all uses replaced by pthread_sigmask etc. calls.
5793 * syssignal.h: Include <signal.h>.
5794 (emacs_sigaction_init, forwarded_signal): New decls.
5795 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
5796 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
5797 (sigmask, sys_sigmask): Remove; no longer needed.
5798 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
5799 (sigblock, sigunblock, sigfree):
5800 (sigsetmask) [!defined sigsetmask]:
5801 Remove. All uses replaced by pthread_sigmask.
5802 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
5803 no longer need to be replaced, and its typical old uses
5804 are now done via emacs_sigaction_init and sigaction.
5805 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
5806 (sys_sigdel): Remove; unused.
5807 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
5809 2012-09-06 Eli Zaretskii <eliz@gnu.org>
5811 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
5812 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
5814 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5816 Explicitly mark buffer_defaults and buffer_local_symbols.
5817 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
5818 mark_local_symbols here.
5819 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
5820 since special buffers aren't marked here any more.
5821 (allocate_buffer): Chain new buffer with all_buffers here...
5822 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
5824 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
5825 (syms_of_buffer): Remove staticpro of the above.
5826 (init_buffer_once): Set names for buffer_defaults and
5827 buffer_local_symbols.
5829 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
5831 Use bool for booleans in font-related modules.
5832 * font.c (font_intern_prop, font_style_to_value)
5833 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
5834 (generate_otf_features, font_check_otf_features, font_check_otf)
5835 (font_match_p, font_list_entities, font_at):
5836 * fontset.c (fontset_id_valid_p, reorder_font_vector
5837 (fontset_find_font, Fset_fontset_font)
5838 (face_suitable_for_char_p) [0]:
5839 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
5840 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
5841 (m17n_flt_initialized, ftfont_shape_by_flt):
5842 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
5843 * nsfont.m (nsfont_draw):
5844 * w32font.c (w32font_draw):
5845 * w32term.c (x_draw_glyphless_glyph_string_foreground):
5846 Use bool for booleans.
5847 * font.h: Adjust to above API changes.
5848 (struct font, struct font_driver, struct font_driver_list):
5849 Use bool for booleans.
5850 (struct font): Remove useless member encoding_type.
5852 * fontset.c, xftfont.c: Omit unnecessary static decls.
5854 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
5856 * alloc.c (mark_object): Revert window marking code
5857 since it's unsafe for the Fset_window_configuration.
5859 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5861 Fix race conditions with signal handlers and errno (Bug#12327).
5862 Be more systematic about preserving errno whenever a signal
5863 handler returns, even if it's not in the main thread. Do this by
5864 renaming signal handlers to distinguish between signal delivery
5865 and signal handling. All uses changed.
5866 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
5867 * data.c (deliver_arith_signal): Rename from arith_error.
5868 * dispnew.c (deliver_window_change_signal): Rename from
5869 window_change_signal.
5870 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
5871 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
5872 * keyboard.c (deliver_input_available_signal): Rename from
5873 input_available_signal.
5874 (deliver_user_signal): Rename from handle_user_signal.
5875 (deliver_interrupt_signal): Rename from interrupt_signal.
5876 * process.c (deliver_pipe_signal): Rename from send_process_trap.
5877 (deliver_child_signal): Rename from sigchld_handler.
5878 * atimer.c (handle_alarm_signal):
5879 * data.c (handle_arith_signal):
5880 * dispnew.c (handle_window_change_signal):
5881 * emacs.c (handle_fatal_signal, handle_danger_signal):
5882 * keyboard.c (handle_input_available_signal):
5883 * keyboard.c (handle_user_signal, handle_interrupt_signal):
5884 * process.c (handle_pipe_signal, handle_child_signal):
5885 New functions, with the actual signal-handling code taken from the
5886 original respective signal handlers, sans the sporadic attempts to
5887 preserve errno, since that's now done by handle_on_main_thread.
5888 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
5889 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
5890 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5892 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5893 Move initialization of main_thread to sysdep.c's init_signals.
5894 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
5895 our usage, and simplifies the mainline code.
5896 (record_child_status_change): New static function, as a helper
5897 for handle_child_signal, and with most of the old child handler's
5899 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
5900 (handle_child_signal): Use the above.
5901 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
5902 Moved here from emacs.c.
5903 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
5904 code moved here from emacs.c's main function.
5905 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
5906 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
5907 This lets callers save and restore errno properly.
5909 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5911 Remove redundant or unused things here and there.
5912 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
5913 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
5914 * editfns.c (Fcompare_buffer_substrings): Likewise.
5915 * frame.h (struct terminal, struct font_driver_list):
5916 Remove redundant declarations.
5917 * window.h (Qleft, Qright): Likewise.
5919 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5921 Do not mark objects from deleted buffers, windows and frames.
5922 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
5923 (mark_object): Likewise for windows and frames.
5925 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
5927 * alloc.c (valid_lisp_object_p): Treat killed buffers,
5928 buffer_defaults and buffer_local_symbols as valid objects.
5929 Return special value to denote them.
5931 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
5933 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
5934 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
5935 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
5936 (file_name_absolute_p, Fsubstitute_in_file_name):

5939 (Finsert_file_contents, choose_write_coding_system)
5940 (Fwrite_region, build_annotations, a_write, e_write)
5942 * filelock.c (boot_time_initialized, get_boot_time)
5943 (get_boot_time_1, lock_file_1, within_one_second):
5944 * floatfns.c (in_float):
5945 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
5946 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
5947 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
5948 * lisp.h (struct Lisp_Hash_Table.cmpfn):
5949 * window.c (compare_window_configurations):
5950 Use bool for booleans.
5951 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
5952 (Fdefault_file_modes): Now mode_t, not int, for modes.
5953 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
5954 (internal_delete_file): Now returns void, not a (boolean) int,
5955 since nobody was looking at the return value.
5956 * lisp.h, window.h: Adjust to above API changes.
5958 * xdisp.c (set_message): Simplify and reindent last change.
5960 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
5962 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
5964 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
5966 * eval.c (call_debugger): Make the function non-static so that we
5967 can call it from set_message.
5969 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
5970 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
5972 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5974 Give more-useful info on a fatal error (Bug#12328).
5975 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
5976 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
5977 of doing the work ourselves.
5978 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
5979 do most of the work.
5980 (fatal_error_backtrace): New function, taken from the guts
5981 of the old fatal_error_signal, but with a new option to output
5983 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
5984 info about the signal than just its number.
5985 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
5986 * sysdep.c: Include <execinfo.h>
5987 (emacs_backtrace): New function, taken partly from the previous
5988 code of the 'die' function.
5989 (emacs_abort): Call fatal_error_backtrace rather than abort.
5991 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
5993 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
5994 eager (load-time) macro-expansion.
5995 * lisp.mk (lisp): Add macroexp.
5997 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
5999 Simplify redefinition of 'abort' (Bug#12316).
6000 Do not try to redefine the 'abort' function. Instead, redo
6001 the code so that it calls 'emacs_abort' rather than 'abort'.
6002 This removes the need for the NO_ABORT configure-time macro
6003 and makes it easier to change the abort code to do a backtrace.
6004 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6005 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6006 Remove; sysdep.c's emacs_abort now takes its place.
6007 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6008 'abort' changed to use 'emacs_abort'.
6009 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6010 (abort) [!defined abort]: Rename to ...
6011 (emacs_abort): ... new name.
6012 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6013 the place of the old 'abort' in emacs.c.
6014 * w32.c, w32fns.c (abort): Do not #undef.
6015 * w32.c (emacs_abort): Rename from w32_abort.
6017 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6019 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6020 offsets[j].dv, since the y axis of the screen coordinates points
6021 down, while the y axis of the font definition coordinates points
6022 up. This fixes display of Arabic diacritics such as KASRA and
6023 KASRATAN. (Bug#11860)
6025 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6027 Be more systematic about _setjmp vs setjmp.
6028 * alloc.c (test_setjmp, mark_stack):
6029 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6030 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6031 (png_load, my_error_exit, jpeg_load):
6032 * process.c (send_process_trap, send_process):
6033 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6034 The underscored versions are up to 30x faster on some hosts.
6035 Formerly, the code used setjmp+longjmp sometimes and
6036 _setjmp+_longjmp at other times, with no particular reason to
6037 prefer setjmp+longjmp.
6039 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
6041 Fix minor problem found by static checking.
6042 * buffer.c (Fdelete_all_overlays): Return nil.
6044 2012-09-03 Martin Rudalics <rudalics@gmx.at>
6046 * buffer.c (Fdelete_all_overlays): New function.
6048 2012-09-03 Chong Yidong <cyd@gnu.org>
6050 * gtkutil.c: Add extern decl for Qxft.
6052 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
6054 * emacs.c, eval.c: Use bool for boolean.
6055 * emacs.c (initialized, inhibit_window_system, running_asynch_code):

6066 All callers changed.
6067 * eval.c (interactive_p): Omit always-true boolean argument
6068 EXCLUDE_SUBRS_P. All callers changed.
6069 * dispextern.h, lisp.h: Reflect above API changes.
6070 * firstfile.c (dummy): Use the address of 'main', whose signature
6071 won't change, instead of the address of 'initialize', whose
6072 signature just changed from int to bool.
6073 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6074 * msdos.c (fatal_error_in_progress): ... from here.
6075 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6077 (redisplay_internal, unwind_redisplay): Simply clear
6078 REDISPLAYING_P when unwinding, instead of saving its previous,
6079 always-false value and then restoring it.
6081 Clean up some extern decls.
6082 Mostly, this hoists extern decls out of .c files and into .h files.
6083 That way, we're more likely to catch errors if the interfaces change.
6084 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6085 declare xg_mark_data.
6086 * dispextern.h (x_frame_parm_handlers):
6088 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
6089 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)

6104 * xfont.c (x_clear_errors):
6105 * xterm.c (x_frame_parm_handlers):
6106 Remove now-redundant extern decls.
6107 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6108 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6110 * xfaces.c: Remove unnecessary static decls.
6111 * xterm.c (updating_frame): Remove decl of nonexistent object.
6113 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6114 when building globals.h, as the objects that are not built on
6115 this host are not needed to compile C files on this host.
6117 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6119 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6147 * keyboard.c (decode_timer):
6148 Use bool for boolean.
6149 * intervals.h, lisp.h, systime.h: Reflect above API changes.

6157 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
6159 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
6160 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

6167 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6169 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6170 more than one grapheme cluster passed to the shaper: compute the
6171 offset adjustment values separately for each cluster. (Bug#11860)
6173 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6174 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6175 about implicit conversions from integer to pointer.
6177 2012-09-01 Daniel Colascione <dancol@dancol.org>
6179 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
6180 system used too early.
6182 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
6184 Better seed support for (random).

6217 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
6219 * menu.c: Include TERM_HEADER instead of listing all possible
6220 window-system headers.
6222 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
6225 * keyboard.c: Include TERM_HEADER instead of listing all possible
6226 window-system headers.
6228 * image.c: Include TERM_HEADER instead of listing all possible
6229 window-system headers. Declare Vlibrary_cache when compiling for
6232 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
6233 window system declarations.
6235 * frame.h: Move common functions here: set_frame_menubar,
6236 x_set_window_size, x_sync, x_get_focus_frame,
6237 x_set_mouse_position, x_set_mouse_pixel_position,
6238 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

6262 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6264 Remove mark_ttys function and fix tty_display_info initialization.
6265 * lisp.h (mark_ttys): Remove prototype.
6266 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
6267 to mark_ttys because all possible values of 'top_frame' slot are
6268 the frames which are reachable from Vframe_list.
6269 * term.c (mark_ttys): Remove.
6270 (init_tty): Safely initialize 'top_frame' slot with Qnil.
6272 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
6274 Change struct frame bitfields from unsigned char to unsigned.
6275 * frame.h (struct frame): Change type of 'display_preempted',

6277 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
6278 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
6279 bitfields from unsigned char to unsigned.

6292 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
6294 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
6295 for GCC 4.7.1 x86-64.
6297 2012-08-30 Glenn Morris <rgm@gnu.org>
6299 * lread.c (init_lread): For out-of-tree builds, only add the
6300 source directory's site-lisp dir to the load-path if it exists,
6301 consistent with in-tree builds. (Bug#12302)
6303 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
6305 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

6314 (addString:row:): Remove return self, declare return value as void.
6315 (addSplit): Remove return self, declare return value as void.
6316 (clicked:): Remove return self, declare return value as void.
6317 Set dialog_return to button_values[seltag]. Code formatting change.
6318 (initFromContents:isQuestion:): Adjust call to process_dialog.
6319 Code formatting change.
6320 (timeout_handler:): Set timer_fired to YES.
6321 (runDialogAt:): Set timer_fired to NO.
6322 Handle click on close button as quit.
6324 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
6325 Add window_closed and button_values. Add void as return value for
6326 add(Button|String|Split). addButton takes int instead of Lisp_Object.
6327 Add process_dialog as new member.
6329 2012-08-28 Eli Zaretskii <eliz@gnu.org>
6331 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
6332 is not one of the heaps we manage. (Bug#12242)

6393 Use bool for boolean.
6394 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
6395 and remove last int (actually boolean) argument, which was always 0.
6396 All callers changed.
6397 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
6398 * dispextern.h (struct composition_it): Use bool for boolean.
6399 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
6400 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
6401 * dired.c (file_name_completion):
6402 Use bool for boolean. (This was missed in an earlier change.)
6404 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6406 * window.c (Fset_window_configuration): Revert first part of
6409 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
6411 * nsterm.h (NSPanel): New class variable dialog_return.
6413 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
6414 Initialize dialog_return.
6415 (windowShouldClose:): Use stop instead of stopModalWithCode.
6416 (clicked:): Ditto, and also set dialog_return (Bug#12258).
6417 (timeout_handler:): Use stop instead of abortModal. Send a dummy
6419 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
6422 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
6424 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
6425 * composite.c (find_composition, composition_gstring_p)
6426 (composition_reseat_it, find_automatic_composition):

6432 * dbusbind.c (xd_in_read_queued_messages):
6433 * dired.c (directory_files_internal, file_name_completion):
6434 Use bool for booleans.
6435 * dired.c (file_name_completion):
6436 * process.h (fd_callback):
6437 Omit int (actually boolean) argument. It wasn't being used.
6439 * composite.h, lisp.h: Reflect above API changes.
6441 * cmds.c, coding.c: Use bool for booleans.
6442 * cmds.c (move_point, Fself_insert_command):

6462 (Fset_coding_system_priority):
6463 * fileio.c (Finsert_file_contents):
6464 Use bool for booleans.
6465 * coding.h, lisp.h: Reflect above API changes.
6466 * coding.c: Remove unnecessary static function decls.
6467 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
6468 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
6469 not a boolean 'int', since callers never look at the return value.
6470 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
6471 * coding.h (decoding_buffer_size, encoding_buffer_size)
6472 (emacs_mule_string_char): Remove unused extern decls.
6473 (struct iso_2022_spec, struct coding_system):
6474 Use 'unsigned int : 1' for boolean fields, since there's more than one.
6475 (struct emacs_mule_spec): Remove unused field 'full_support'.
6476 All initializations removed.
6477 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
6479 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6481 Fix spare memory change (Bug#12286).
6482 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
6483 (valid_lisp_object_p): Likewise.
6485 2012-08-27 Martin Rudalics <rudalics@gmx.at>
6487 * window.c (Fset_window_configuration): Record any window's old
6488 buffer if it's replaced (see Bug#8789). If the new current
6489 buffer doesn't appear in the selected window, go to its old
6492 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
6494 Special MEM_TYPE_SPARE to denote reserved memory.
6495 * alloc.c (enum mem_type): New memory type.
6496 (refill_memory_reserve): Use new type for spare memory.
6497 This prevents live_cons_p and live_string_p from incorrect
6498 detection of uninitialized objects from spare memory as live.
6500 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
6503 * Makefile.in (.PHONY): versioclean -> versionclean.
6505 Remove unused external symbols.
6506 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
6507 * window.c (Qwindow_valid_p, decode_valid_window):
6508 Now static, not extern.
6509 * data.c (Qinterval): Remove; unused.
6510 (syms_of_data): Do not define 'interval'.
6511 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
6512 * window.h (decode_valid_window):
6515 * character.c, charset.c, chartab.c: Use bool for booleans.
6516 * character.c (lisp_string_width, string_count_byte8)
6517 (string_escape_byte8):
6518 * charset.c (charset_map_loaded, load_charset_map, read_hex):
6519 (load_charset_map_from_file, map_charset_chars)
6520 (Fdefine_charset_internal, define_charset_internal)
6521 (Fdeclare_equiv_charset, find_charsets_in_text)
6522 (Ffind_charset_region, char_charset, Fiso_charset):

6524 (sub_char_table_set, sub_char_table_set_range)
6525 (char_table_set_range, optimize_sub_char_table)
6526 (map_sub_char_table):
6527 Use bool for boolean.
6528 * character.c (str_to_unibyte): Omit last boolean argument; it was
6529 always 0. All callers changed.
6530 * character.h, charset.h: Adjust to match previous changes.
6531 * character.h (char_printable_p): Remove decl of nonexistent function.
6532 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
6533 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
6534 are all boolean, so make them single-bit bitfields.
6536 * lisp.h (ASET): Remove attempt to detect side effects.
6537 It was meant to be temporary and it often doesn't work,
6538 because when IDX has side effects the behavior of IDX==IDX
6539 is undefined. See Stefan Monnier in
6540 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
6542 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
6544 * lisp.h (functionp): New function (extracted from Ffunctionp).
6545 (FUNCTIONP): Use it.
6546 * eval.c (Ffunctionp): Use it.
6548 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6550 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
6551 as that's faster and simpler than static storage. Don't bother
6552 with the g_main_context_query overhead if g_main_context_pending
6553 says no events are pending.
6554 (gfds, gfds_size): Remove these static vars.
6555 (xgselect_initialize): Remove; no longer needed.
6556 All uses and decls removed.
6558 * emacs.c (fatal_error_signal_hook): Remove.
6559 All uses removed. This leftover from old code was always 0.
6561 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
6562 * casefiddle.c (casify_object, casify_region):
6563 * casetab.c (set_case_table):
6564 * category.c, category.h (word_boundary_p):
6565 * category.h (CHAR_HAS_CATEGORY):
6566 Use bool for booleans, instead of int.
6568 2012-08-25 Eli Zaretskii <eliz@gnu.org>
6570 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
6572 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
6574 On assertion failure, print backtrace if available.
6575 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
6576 (die) [ENABLE_CHECKING]: Print a backtrace if available.
6577 * Makefile.in (LIB_EXECINFO): New macro.
6580 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
6581 * bytecode.c (exec_byte_code):
6582 * callint.c (check_mark, Fcall_interactively):
6583 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
6584 (getenv_internal, sync_process_alive, call_process_exited):
6585 * lisp.h (USE_SAFE_ALLOCA):
6586 Use bool for booleans, instead of int.
6587 * lisp.h, process.h: Adjust prototypes to match above changes.
6588 * callint.c (Fcall_interactively): Don't assume the mark's
6589 offset fits in 'int'.
6591 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
6593 * buffer.c, buffer.h: Use bool for boolean.
6594 * buffer.c (reset_buffer_local_variables)
6595 (buffer_lisp_local_variables, Fset_buffer_modified_p)
6596 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
6597 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
6598 (overlay_touches_p, overlay_strings, Foverlay_put)
6599 (report_overlay_modification, call_overlay_mod_hooks):
6600 (mmap_enlarge, mmap_set_vars):
6601 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
6602 Use bool for booleans, instead of int.
6603 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
6604 since the 1-or-0 return value is always ignored anyway.
6605 (mmap_initialized_p):
6606 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
6607 * buffer.h, lisp.h: Adjust prototypes to match above changes.
6609 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6611 * bidi.c: Use bool for boolean.
6612 This is a bit more readable, and makes the text segment of bidi.o
6613 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
6614 Presumably it's faster too.
6615 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
6617 (bidi_cache_find_level_change, bidi_cache_iterator_state)
6618 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
6619 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
6620 (bidi_explicit_dir_char, bidi_level_of_next_char)
6621 (bidi_find_other_level_edge, bidi_move_to_visually_next):
6622 Use bool for booleans, instead of int.
6623 * dispextern.h (bidi_init_it, bidi_paragraph_init)
6624 (bidi_unshelve_cache): Adjust decls to match code.
6626 2012-08-23 Martin Rudalics <rudalics@gmx.at>
6628 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
6631 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
6633 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
6634 * atimer.h: Include <stdbool.h>.
6636 2012-08-22 Dan Nicolaescu <dann@gnu.org>
6638 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
6639 compile time tests instead of run time tests on systems that do
6641 (FRAME_MAC_P): Remove leftover from deleted code.
6642 * frame.c (syms_of_frame): Remove leftover from deleted code.
6644 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
6646 * nsterm.m (insertText:): Don't clear modifiers if code is space.
6648 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
6650 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
6651 Otherwise, the compiler complains about (A?B:C) where B is void
6652 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
6653 (fontset_add): Return void, for FONTSET_ADD.
6655 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6657 * alloc.c: Use bool for booleans.
6658 (gc_in_progress, abort_on_gc)
6659 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6660 (dont_register_blocks) [GC_MALLOC_CHECK]:
6661 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
6662 (check_string_bytes, make_specified_string, memory_full)
6663 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
6664 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
6665 (mark_stack, valid_pointer_p, make_pure_string)
6666 (Fgarbage_collect, survives_gc_p, gc_sweep):
6667 Use bool for booleans, instead of int.
6668 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
6669 Remove unused local.
6670 * alloc.c (PURE_POINTER_P):
6671 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
6672 * editfns.c (Fformat):
6673 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
6675 * fns.c (sweep_weak_table):
6676 * lisp.h (suppress_checking, push_message, survives_gc_p)
6677 (make_pure_string, gc_in_progress, abort_on_gc):
6678 * lread.c (readchar, read1):
6679 * print.c (Fprin1_to_string):
6680 * xdisp.c (push_message):
6681 Use bool for booleans affected directly or indirectly by
6684 Make recently-introduced setters macros.
6685 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
6686 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
6687 (set_fontset_default, set_fontset_fallback): Rename from their
6688 upper-case counterparts, and make them functions rather than macros.
6689 This is more consistent with the other recently-introduced setters.
6690 These don't need to be inline, since they're local.
6692 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
6694 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
6695 the loop (Bug#12247).
6697 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6699 * lisp.h (vcopy): Use memcpy rather than our own loop.
6700 This fixes a performance regression introduced by the recent
6701 addition of vcopy. This means 'vcopy' will need to be modified
6702 for a copying collector, but that's OK. Also, tighten the
6703 checking in the assertion.
6705 2012-08-21 Eli Zaretskii <eliz@gnu.org>
6707 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
6708 components for RTL text (Bug#11860). Adjust X-OFFSET of each
6709 non-base glyph for the width of the base character, according to
6710 what x_draw_composite_glyph_string_foreground expects.
6711 Generate WADJUST value according to composition_gstring_width's
6712 expectations, to produce correct width of the composed character.
6713 Reverse the sign of the DU offset produced by ScriptPlace.
6715 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
6717 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
6719 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6721 Avoid direct writes to contents member of struct Lisp_Vector.
6722 * lisp.h (vcopy): New function to copy data into vector.
6723 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
6724 * fns.c (Ffillarray): Use ASET.
6725 * keyboard.c (timer_check_2): Use AREF and ASET.
6726 (append_tool_bar_item, Frecent_keys): Use vcopy.
6727 * lread.c (read_vector): Use ASET.
6728 * msdos.c (Frecent_doskeys): Use vcopy.
6729 * xface.c (Finternal_copy_lisp_face): Use vcopy.
6730 (Finternal_merge_in_global_face): Use ASET and vcopy.
6731 * xfont.c (xfont_list_pattern): Likewise.
6733 2012-08-21 Martin Rudalics <rudalics@gmx.at>
6735 * window.c (Fwindow_point): For the selected window always return
6736 the position of its buffer's point.
6737 (Fset_window_point): For the selected window always go in its
6738 buffer to the specified position.
6740 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
6742 Setter macros for fontsets.
6743 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
6744 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
6745 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
6748 2012-08-20 Glenn Morris <rgm@gnu.org>
6750 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
6751 Don't assume that `ln -f' works.
6753 2012-08-20 Eli Zaretskii <eliz@gnu.org>
6755 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
6756 and later about non-assignments with no effect. See discussion at
6757 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
6760 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6762 Inline setter functions for Lisp_Objects slots of struct specbinding.
6763 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
6766 2012-08-20 Martin Rudalics <rudalics@gmx.at>
6768 * window.c (select_window): Always make selected window's buffer
6771 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6773 Use AREF and ASET for docstrings of category tables.
6774 * category.h (CATEGORY_DOCSTRING): Use AREF.
6775 (SET_CATEGORY_DOCSTRING): Use ASET.
6776 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
6778 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6780 Inline setter functions for hash table members.
6781 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
6782 (set_hash_hash, set_hash_index): Rename with _slot suffix.
6783 (set_hash_key_and_value, set_hash_index, set_hash_next)
6784 (set_hash_hash): New functions.
6785 * charset.c, fns.c: Adjust users.
6787 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
6789 Inline getter and setter functions for per-buffer values.
6790 * buffer.h (per_buffer_default, set_per_buffer_default)
6791 (per_buffer_value, set_per_buffer_value): New functions.
6792 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
6793 * buffer.c, data.c: Adjust users.
6795 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
6797 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
6799 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
6801 Rely on <config.h> + <unistd.h> to declare 'environ',
6802 as gnulib does this if the system doesn't.
6803 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
6804 Remove declaration. MS-Windows declares it on stdlib.h which is
6805 included by conf_post.h.
6806 * emacs.c (environ) [DOUG_LEA_MALLOC]:
6807 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
6808 * vm-limit.c: Include <unistd.h>, for 'environ'.
6810 * unexaix.c, unexcoff.c: Include "mem-limits.h".
6811 (start_of_data): Remove decl; mem-limits.h provides it.
6813 * xdisp.c (handle_invisible_prop): Make it a bit faster
6814 and avoid a gcc -Wmaybe-uninitialized diagnostic.
6816 2012-08-19 Chong Yidong <cyd@gnu.org>
6818 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
6821 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
6823 * .gdbinit: Use call instead of set when calling a function in the
6826 * data.c (set_internal): Don't use set_blv_found.
6827 (Fkill_local_variable): Likewise.
6829 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
6831 * nsfont.m (ns_ascii_average_width): Ensure the string
6832 ascii_printable is initialized with a null-terminated character
6833 array. Otherwise, it can contain undesired extra characters.
6835 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
6837 port new setting code to Sun C 5.8 2005/10/13
6838 * chartab.c, lisp.h (char_table_set, char_table_set_range):

7227 Use bool, not int, for Lisp booleans.

7706 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
7708 Export DEFAULT_REHASH_* to GDB.
7709 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
7710 Now constants, not macros.
7712 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
7714 Remove unnecessary casts involving pointers.
7715 These casts are no longer needed now that we assume C89 or later,
7716 since they involve casting to or from void *.
7717 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
7718 (make_pure_float, make_pure_vector):
7719 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

7721 * menu.c (find_and_return_menu_selection):
7722 * minibuf.c (read_minibuf_noninteractive):
7723 * sysdep.c (closedir):
7724 * xdisp.c (x_produce_glyphs):
7725 * xfaces.c (compare_fonts_by_sort_order):
7726 * xfns.c (x_real_positions, select_visual):
7727 * xselect.c (x_stop_queuing_selection_requests)
7728 (x_get_window_property, x_get_window_property_as_lisp_data):
7729 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
7730 Remove unnecessary pointer casts.
7731 * alloc.c (record_xmalloc): New function.
7732 * lisp.h (record_xmalloc): New decl.
7733 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
7734 more like a function. This is because the pointer cast is not
7735 needed. All uses changed.
7736 * print.c (print_string, print_error_message): Avoid length recalc.
7738 Improve fix for macroexp crash with debugging (Bug#12118).
7739 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
7740 ARRAY_MARK_FLAG when checking subscripts, because ASET is
7741 not supposed to be invoked from the garbage collector.
7742 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
7743 (gc_aset): New function, which is like ASET but can be
7744 used in the garbage collector.
7745 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
7746 (set_hash_index): Use it instead of ASET.
7748 2012-08-03 Eli Zaretskii <eliz@gnu.org>

7755 <g_b_init_create_symbolic_link>: New static flags.
7756 (globals_of_w32): Initialize them to zero.
7757 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
7758 (map_w32_filename): Improve commentary. Simplify switch.
7759 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
7760 headers (most versions of MinGW w32api don't).
7761 (get_security_info, create_symbolic_link)
7762 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
7764 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
7765 in the argument file name.

7767 GetFileAttributes fails with network-related error codes.
7768 (sys_rename): Diagnose renaming of a symlink when the user doesn't
7769 have the required privileges.
7770 (get_file_security_desc_by_name): Rename from
7771 get_file_security_desc.
7772 (stat_worker): New function, with most of the guts of 'stat', and
7773 with addition of handling of symlinks and support for 'lstat'.
7774 If possible, get file's attributes and security information by
7775 handle, not by name. Produce S_IFLNK bit for symlinks, when
7776 called from 'lstat'.
7777 (stat, lstat): New functions, call 'stat_worker'.
7778 (symlink, readlink, careadlinkat): Rewritten to create and resolve
7779 symlinks when the underlying filesystem supports them.
7781 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
7783 Fix macroexp crash on Windows with debugging (Bug#12118).
7784 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
7785 checking subscripts; problem introduced with the recent
7786 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
7787 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
7788 since it's used in non-static inline functions now.
7790 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
7791 Don't assume buffer size fits in 'int'. Remove unused local.
7793 Use C99-style 'extern inline' if available.

7802 New macro, replacing 'static inline' in this header.
7803 * buffer.h, category.h, character.h, charset.h, composite.h:
7804 * dispextern.h, lisp.h, systime.h:
7805 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
7806 * alloc.c (LISP_INLINE):
7807 * buffer.c (BUFFER_INLINE):
7808 * category.c (CATEGORY_INLINE):
7809 * character.c (CHARACTER_INLINE):
7810 * charset.c (CHARSET_INLINE):
7811 * composite.c (COMPOSITE_INLINE):
7812 * dispnew.c (DISPEXTERN_INLINE):
7813 * sysdep.c (SYSTIME_INLINE):
7814 Define to EXTERN_INLINE, so that the corresponding functions
7815 are compiled into code.
7816 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
7817 (INLINE_HEADER_END): New macros.
7818 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,
7819 since it's used in non-static inline functions now.

7838 hard-coding the path separator.
7840 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
7842 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
7843 This how ASET and AREF are supposed to work, and makes
7844 it easier to think about future improvements. See
7845 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
7846 * charset.h (set_charset_attr): New function.
7847 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
7848 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

8105 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>

8120 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):

8261 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
8262 enumeration constants, as PURE and HEAP are too general, and clash
8263 with other headers and sources, such as gmalloc.c and the
8264 MS-Windows system headers. All users changed.
8266 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
8268 Revert last save_excursion_save and save_excursion_restore changes.
8269 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

8282 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
8283 arms of an 'if', not using conditional expressions; otherwise GDB
8284 complains about the types in the unevaluated arm when the argument
8285 is an integer literal.
8286 (xgetint): Simplify expression.
8287 * alloc.c (gdb_make_enums_visible): New constant. This ports to
8288 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
8289 Zaretskii in <http://bugs.gnu.org/12036#13>.
8290 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
8291 needed now that we have gdb_make_enums_visible.
8292 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
8293 (enum enum_USE_LSB_TAG):
8294 New enum types, packaging up enums that need to be exported to GDB.

8336 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
8337 emacs.c, as this is a more-suitable home. Had this been done earlier
8338 the fix for 12036 would have avoided some of the problems noted in
8339 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
8340 would have been more obvious.
8341 * emacs.c: Do not include <verify.h>; no longer needed.
8342 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
8343 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
8344 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

8350 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
8351 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
8352 not be usable in #if. This simplifies things.
8354 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
8356 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

8361 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
8362 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
8363 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
8364 Adjust to changes in lisp.h and emacs.c, by using
8365 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
8366 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
8367 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
8368 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
8369 instead of gdb_valbits.
8370 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
8371 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
8372 instead of gdb_array_mark_flag.
8373 (xboolvector): Get size from $->size, not $->header.size.
8374 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
8375 (xreload, hook-run, hookpost-run): Remove.
8376 * emacs.c: Include <verify.h>.
8377 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
8378 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
8380 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
8381 (gdb_USE_LSB_TAG): New enum constants.
8382 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
8383 Also define these as enum constants, so they're visible to GDB.
8384 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
8385 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
8386 as constants, so they're visible to GDB.

8389 Now enum constants, not macros, so they're visible to GDB.
8390 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
8391 more convenient now. All uses changed.
8392 (VALMASK) [USE_LSB_TAG]: Also define in this case.
8393 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
8395 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

8402 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
8403 add argument, tune behavior, and adjust all callers.
8405 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
8407 Use typedef for EMACS_INT, EMACS_UINT.
8408 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
8409 than macros. This simplifies debugging in the usual case, since
8410 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
8411 and it allows expressions involving EMACS_INT casts.
8412 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
8414 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

8426 Adjust buffer text indirection counters at the end of Fkill_buffer.
8427 * buffer.c (Fkill_buffer): Adjust indirection counters when the
8428 buffer is definitely dead. This should really fix an issue reported
8429 by Christoph Scholtes again. (Bug#12007).
8430 (init_buffer_once): Initialize indirection counters of
8431 buffer_defaults and buffer_local_symbols (for sanity and safety).
8433 2012-07-24 Eli Zaretskii <eliz@gnu.org>
8435 * xdisp.c (init_iterator): Don't compute dimensions of truncation
8436 and continuation glyphs on tooltip frames, leave them at zero.

8464 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
8466 Swap buffer text indirection counters in Fbuffer_swap_text.
8467 * buffer.c (Fbuffer_swap_text): Swap indirections too.
8468 This avoids crash reported by Christoph Scholtes at
8469 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
8471 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
8473 * nsmenu.m (Popdown_data): New struct.
8474 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
8476 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
8477 (initWithContentRect): Make imgView and contentView non-static
8478 and autorelease them. Also autorelease img and matrix (Bug#12005).
8479 (dealloc): Remove (Bug#12005).
8481 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
8483 Adjust consing_since_gc when objects are explicitly freed.

8496 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
8498 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
8499 as it's limited by the amount of memory, not by INT_MAX.
8501 2012-07-21 Eli Zaretskii <eliz@gnu.org>
8503 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
8504 in special-event-map. See the discussion at

8563 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
8564 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
8565 Adjust users accordingly.

9227 * s/aix4-2.h (unix): Remove; no longer needed.
9229 EMACS_TIME simplification (Bug#11875).
9230 This replaces macros (which typically do not work in GDB)
9231 with functions, typedefs and enums, making the code easier to debug.
9232 The functional style also makes code easier to read and maintain.
9233 * systime.h: Include <sys/time.h> on all hosts, not just if
9234 WINDOWSNT, since 'struct timeval' is needed in general.

9250 (add_emacs_time, sub_emacs_time): New functions.
9251 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

9274 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
9275 Prefer snprintf to strncpy.
9276 * nsterm.m (ns_term_init):
9277 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
9278 * nsterm.m (ns_term_init):
9279 Avoid the need for strncpy, by using build_string or
9280 make_unibyte_string directly. Use dtoastr, not snprintf.
9281 * process.c (Fmake_network_process): Diagnose service names that
9282 are too long, rather than silently truncating them or creating
9283 non-null-terminated names.

9300 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
9301 where argument type is known to be a Lisp_Cons.

9356 O_RDONLY already includes it).
9358 Stop ns builds setting the EMACSLOADPATH environment variable.
9359 * nsterm.m (ns_load_path): Rename from ns_init_paths.
9360 Now it does not set EMACSLOADPATH, just returns the load-path string.

9362 * lread.c [HAVE_NS]: Include nsterm.h.
9363 (init_lread) [HAVE_NS]: Use ns_load_path.

9373 (ns_init_paths): Do not set EMACSPATH.

9433 Move marker debugging code under MARKER_DEBUG.
9434 * marker.c (MARKER_DEBUG): Move marker debugging code under
9435 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
9436 for bootstrap with --enable-checking (~3x slowdown reported

9488 2012-07-07 Glenn Morris <rgm@gnu.org>
9490 * lread.c (load_path_check): New function, split from init_lread.
9491 (init_lread): Reorganize. Motivation:
9492 If EMACSLOADPATH is set, check/warn about that rather than the
9493 defaults, which we are not going to use. Hence we can remove
9494 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
9495 Don't warn if site-lisp directories are missing.
9496 If not installed, start from a blank load-path, since
9497 PATH_LOADSEARCH refers to the eventual installation directories.
9499 2012-07-07 Eli Zaretskii <eliz@gnu.org>
9501 Support truncation and continuation glyphs on GUI frames, when
9502 fringes are disabled. (Bug#11832)
9503 * xdisp.c (init_iterator): Get dimensions of truncation and
9504 continuation glyphs even if on GUI frames.
9505 Adjust it->last_visible_x on GUI frames when the left or right fringes,
9506 or both, are absent.
9507 (start_display, move_it_in_display_line_to): Handle the case of a
9508 GUI frame without a fringe to display continuation or truncation
9510 (insert_left_trunc_glyphs): Support GUI frames: make sure
9511 truncation glyphs overwrite enough glyphs from the current line to
9512 have sufficient space in pixels.
9513 (display_line): Support truncation and continuation glyphs on GUI
9514 frames. If some spare pixels are left on the line after inserting
9515 the truncation glyphs, fill that space with a stretch glyph of a
9516 suitably computed width.
9518 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
9519 produce_glyphs, to support GUI sessions.
9521 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
9523 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
9525 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
9527 Do not require float-time's arg to fit in time_t (Bug#11825).
9528 This works better on hosts where time_t is unsigned, and where
9529 float-time is applied to the (negative) difference between two times.
9530 * editfns.c (decode_time_components): Last arg is now double *,
9531 not int *, and means to store all the result as a double, without
9532 worrying about whether the seconds part fits in time_t.
9533 All callers changed.
9534 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
9535 All callers changed.
9536 (Ffloat_time): Do not fail merely because the specified time falls
9537 outside of time_t range.
9539 2012-07-07 Glenn Morris <rgm@gnu.org>
9541 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

9548 Update dependencies.
9550 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
9552 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9554 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
9555 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
9556 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
9557 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
9558 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
9559 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
9561 * xfont.c (compare_font_names): Redo to omit the need for casts.
9563 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
9565 * xfns.c (Fx_change_window_property): Doc fix.
9566 * w32fns.c (Fx_change_window_property): Doc fix.
9568 * w32fns.c (Fx_window_property): Accept the same arguments as the
9569 X Windows version. Doc fix.
9570 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
9572 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
9573 Eli Zaretskii <eliz@gnu.org>
9575 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
9576 Windows-specific code from nt/config.nt moved here.
9577 Obsolete settings removed.
9579 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9581 * process.c: Avoid unnecessary calls to gettime.
9582 (wait_reading_process_output): Don't get the time of day
9583 when gobbling data immediately and not waiting, as there's no need
9584 for it in that case. This removes a FIXME.
9586 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
9588 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
9589 is defined (Bug#11768).
9591 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9593 Fix marker debugging code.
9594 * marker.c (byte_char_debug_check): Do not perform the check
9595 if buffer is not multibyte.
9596 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9597 Call byte_char_debug_check with correct arguments.
9599 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9601 Compile marker debugging code only if ENABLE_CHECKING is defined.
9602 * marker.c (byte_char_debug_check, count_markers):
9603 Use only if ENABLE_CHECKING is defined.
9604 (byte_debug_flag): Remove.
9605 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
9606 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
9608 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9610 Avoid code repetition in marker-related functions.
9611 * marker.c (attach_marker): New function.
9612 (Fset_marker, set_marker_restricted, set_marker_both)
9613 (set_marker_restricted_both): Use it.
9614 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
9615 Consistently rename charno to charpos.
9616 (marker_position): Add eassert.
9617 (marker_byte_position): Convert to eassert.
9619 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9621 Simplify list operations in unchain_overlay and unchain_marker.

9623 * marker.c (unchain_marker): Simplify. Fix comments.
9625 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9627 Introduce fast path for the widely used marker operation.
9628 * alloc.c (build_marker): New function.
9629 * lisp.h (build_marker): New prototype.
9630 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
9631 * composite.c (autocmp_chars): Likewise.
9632 * editfns.c (buildmark): Remove.
9633 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
9634 (save_restriction_save): Use build_marker.
9635 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
9636 * window.c (save_window_save): Likewise.
9638 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
9640 Do not use Fdelete_overlay in delete_all_overlays
9641 to avoid redundant calls to unchain_overlay.
9642 * buffer.c (drop_overlay): New function.
9643 (delete_all_overlays, Fdelete_overlay): Use it.
9644 * minibuf.c (get_minibuffer): Fix comment.
9646 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
9648 Port to OpenBSD 5.1 amd64.
9649 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
9650 This is needed for OpenBSD, and should be harmless on all BSD systems.
9651 Also, include <sys/sysctl.h>, as it should be available on all
9652 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
9653 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
9654 use p_pid member, not kp_proc.pid.
9656 2012-07-06 Glenn Morris <rgm@gnu.org>
9658 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
9660 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9662 More xmalloc and related cleanup.
9663 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
9664 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
9665 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

9669 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
9670 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
9671 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
9673 Omit needless casts involving void * pointers and allocation.
9674 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
9675 as the former is more robust if P's type is changed.
9676 Prefer xzalloc to xmalloc + memset 0.
9677 Simplify malloc-or-realloc to realloc.
9678 Don't worry about xmalloc returning a null pointer.
9679 Prefer xstrdup to xmalloc + strcpy.
9680 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
9682 * keyboard.c (apply_modifiers_uncached): Prefer local array to
9683 alloca of a constant.
9685 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9687 * xdisp.c (display_line): Fix horizontal pixel coordinates when
9688 hscroll is larger than the line width. Fixes long and futile
9689 looping inside extend_face_to_end_of_line (on a TTY) producing
9690 glyphs that are not needed and thrown away.
9692 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9694 * marker.c (set_marker_restricted_both): Simplify by using
9697 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9699 * editfns.c (region_limit): Simplify by using clip_to_bounds.
9701 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
9703 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
9704 not defined (Bug#11768).
9705 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
9706 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
9707 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
9708 followed by gtk_box_set_homogeneous (Bug#11768).
9709 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
9710 (update_theme_scrollbar_width, xg_create_scroll_bar):
9711 Use gtk_scrollbar_new (Bug#11768).
9712 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
9713 (is_box_type): New function (Bug#11768).
9714 (xg_tool_item_stale_p): Call is_box_type.
9715 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
9716 with default display (Bug#11768).
9718 2012-07-05 Eli Zaretskii <eliz@gnu.org>
9720 * xdisp.c (window_hscroll_limited): New function.
9721 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
9722 coordinates when window's hscroll is set to insanely large
9725 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
9727 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
9728 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
9730 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
9733 * lisp.h (xzalloc): New prototype. Omit needless casts.
9734 * alloc.c (xzalloc): New function. Omit needless casts.

9786 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
9788 * fileio.c (time_error_value): Check the right error number.
9789 Problem reported by Troels Nielsen in
9790 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
9792 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9794 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
9795 This should be fixed in a better way; see Eli Zaretskii in
9796 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
9797 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
9799 * fileio.c (time_error_value): Rename from special_mtime.
9800 The old name's problems were noted by Eli Zaretskii in
9801 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
9803 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
9804 This variable's comment says Emacs needs at least one GDB-visible
9805 symbol of type enum pvec_type, to work around GDB problems.
9806 The symbol's value doesn't matter.
9808 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
9809 that causes compilation to fail on pre-C99 compilers.
9811 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
9813 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
9814 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
9816 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9818 * buffer.c (init_buffer_once): Fix initialization of
9819 headers for buffer_defaults and buffer_local_symbols.
9820 Reported by Juanma Barranquero <lekktu@gmail.com>.
9822 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9824 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
9825 * lisp.h (enum pvec_type): Use fewer bits.
9826 (PSEUDOVECTOR_SIZE_BITS): New constant.
9827 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
9828 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
9829 change in pvec_type.
9830 (PSEUDOVECTOR_TYPEP): New macro.
9831 (TYPED_PSEUDOVECTORP): Use it.
9832 * fns.c (internal_equal): Adapt code to extract pvectype.
9833 * emacs.c (gdb_pvec_type): Update type.
9834 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
9835 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
9836 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
9837 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
9838 (sweep_vectors): Use it. Use local var `total_bytes' instead of
9839 abusing vector->header.next.nbytes.
9840 (live_vector_p): Use PVEC_TYPE.
9841 (mark_object): Adapt code to extract pvectype. Use switch.
9843 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9845 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
9846 Tighten new eassert a bit.
9848 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9850 Fix compilation with --enable-gcc-warnings and -O1
9852 * doprnt.c (doprnt): Change type of tem to int, initialize
9853 to avoid compiler warning. Add eassert.
9854 * search.c (simple_search): Initialize match_byte to avoid
9855 compiler warning. Add eassert.
9857 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9859 Avoid weird behavior with large horizontal scrolls.
9860 Without this change, for example, large hscroll values would
9861 mess up Emacs's display on Fedora 15 x86, presumably due to
9862 overflows in int calculations in the display code.
9863 Also, if buffers had long lines, Emacs would freeze.
9864 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
9865 (set_window_hscroll): New function, containing the old guts of
9866 Fset_window_hscroll. Return the clipped value.
9867 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
9868 This avoids the need to check against PTRDIFF_MAX.
9870 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
9872 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
9874 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
9876 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
9878 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
9879 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
9880 since GCC 4.4.6 issues a bogus warning for them.
9882 Fix bugs in file timestamp newness comparisons.
9883 * fileio.c (Ffile_newer_than_file_p):
9884 * lread.c (Fload): Use full timestamp resolution of files,
9885 not just the 1-second resolution, so that files that are only
9886 slightly newer still count as newer.
9887 * fileio.c (Ffile_newer_than_file_p): Don't assume file
9888 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
9890 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
9892 * fileio.c: Improve handling of file time marker. (Bug#11852)
9893 (special_mtime): New function.
9894 (Finsert_file_contents, Fverify_visited_file_modtime):
9895 Use it to set special mtime values consistently.
9897 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
9899 * fileio.c (Finsert_file_contents): Properly handle st_mtime
9900 marker for non-existing file. (Bug#11852)
9902 2012-07-03 Glenn Morris <rgm@gnu.org>
9904 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
9905 and did not make it into globals.h).
9907 2012-07-03 Tom Tromey <tromey@redhat.com>

9943 * xterm.h: Remove EXFUN.
9945 2012-07-03 Glenn Morris <rgm@gnu.org>
9947 * lisp.h (Frandom): Make it visible to C.
9948 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
9949 buffer for invisible buffers. (Bug#1229)
9951 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9953 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
9954 values which aren't power of 2.
9955 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
9956 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
9959 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
9961 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
9963 * alloc.c (mark_object): Revert part of last patch to use `switch'.
9965 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9967 * alloc.c (allocate_vector_block): Remove redundant
9968 calls to mallopt if DOUG_LEA_MALLOC is defined.
9969 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
9970 avoid calls to mallopt if zero_vector is returned.
9972 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9974 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
9975 is enabled, avoid dereferencing NULL current_sblock if
9978 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
9980 Cleanup basic buffer management.
9981 * buffer.h (struct buffer): Change layout to use generic vector
9982 marking code. Fix some comments. Change type of 'clip_changed'
9983 to bitfield. Remove unused #ifndef old.
9984 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
9985 (GET_OVERLAYS_AT): Fix indentation.
9986 (for_each_per_buffer_object_at): New macro.
9987 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
9988 (Fbuffer_local_variables): Use it.
9989 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
9990 * alloc.c (allocate_buffer): Adjust to match new layout of
9991 struct buffer. Fix comment.
9992 (mark_overlay): New function.
9993 (mark_buffer): Use it. Use mark_vectorlike to mark normal
9994 Lisp area of struct buffer.
9995 (mark_object): Use it. Adjust marking of misc objects
9996 and related comments.
9998 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10000 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10001 wrapper that is not needed because the wrapped code is a no-op (zero
10002 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10003 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10005 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10007 * alloc.c (mark_buffer): Simplify. Remove prototype.
10008 (mark_object): Add comment. Reorganize marking of vector-like
10009 objects. Use CHECK_LIVE for all vector-like objects except buffers
10010 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10011 Avoid redundant calls to mark_vectorlike for bool vectors.
10013 2012-06-30 Glenn Morris <rgm@gnu.org>
10015 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10017 * epaths.in (PATH_SITELOADSEARCH): New.
10018 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10019 This is rather than relying on --enable-locallisppath elements
10020 having "site-lisp" in their names. (Bug#10208#25, 11658)
10022 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10024 * w32proc.c (sys_select): Accept and ignore one more argument.
10026 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10028 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10029 (pselect) [!MS_DOS]: Redirect to sys_select.
10031 * sysdep.c: Don't include dos.h and dosfns.h.
10033 * process.c (sys_select):
10034 * msdos.c (sys_select): Accept one more argument and ignore it.
10036 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10037 adapt data types and code to that.
10040 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10041 which clashes with the gnulib function of the same name.
10043 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10045 * font.c (font_style_to_value, font_style_symbolic)
10046 (font_prop_validate_style): Add type checks for values in
10049 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10051 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10054 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10056 * xdisp.c (try_window_id): Undo last change.
10058 * w32.c (getwd): Adjust commentary about startup_dir.
10059 (init_environment): Always call sys_access, even in non-MSVC
10060 builds. Don't chdir to the directory of the Emacs executable.
10061 This undoes code from 1997 which was justified by the need to
10062 "avoid conflicts when removing and renaming directories". But its
10063 downside was that every relative file name was being interpreted
10064 relative to the directory of the Emacs executable, which can never
10065 be TRT. In particular, it broke sys_access when called with
10066 relative file names.
10067 (sys_access): Map GetLastError to errno.
10069 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10071 * window.h (struct window): Change type of 'fringes_outside_margins'

10073 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
10075 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10078 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10080 * gnutls.c (emacs_gnutls_handshake):
10081 Add QUIT to make the loop interruptible.
10083 2012-06-29 Glenn Morris <rgm@gnu.org>
10085 * charset.c (init_charset): Make lack of etc/charsets fatal.
10087 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10089 * editfns.c (region_limit): Fix type mismatch.
10091 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
10093 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10094 undefined. Convert from xassert to eassert.
10095 * nsmenu.m: Convert from xassert to eassert.
10096 * nsterm.m: Likewise.
10098 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
10100 * editfns.c (region_limit): Clip to narrowing (bug#11770).
10102 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
10104 Avoid integer overflow on scroll-left and scroll-right.
10105 * window.c (HSCROLL_MAX): New macro.
10106 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10107 overflow when requested scroll falls outside ptrdiff_t range.
10109 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10111 * window.h (struct window): Change type of 'hscroll',
10112 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10113 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10114 Adjust users accordingly.
10115 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10116 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10117 from EMACS_INT to ptrdiff_t.
10118 (make_window): Omit redundant initialization.

10137 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10138 adjust comments accordingly.

10261 Use sprintf return value instead of invoking strlen on result.
10262 In the old days this wasn't portable, since some sprintf
10263 implementations returned char *. But they died out years ago and
10264 Emacs already assumes sprintf returns int.
10265 Similarly for float_to_string.
10266 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

10272 * xdisp.c (message_dolog):
10273 * xfns.c (syms_of_xfns):
10274 Use sprintf or float_to_string result to avoid need to call strlen.
10275 * data.c (Fnumber_to_string):
10276 Use make_unibyte_string, since the string must be ASCII.
10277 * lisp.h, print.c (float_to_string): Now returns int length.
10278 * term.c (produce_glyphless_glyph):
10279 Use sprintf result rather than recomputing it.
10281 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

10310 * xfns.c (x_window): Remove redundant cast.
10312 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
10314 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
10315 `const char *' to `char *' to avoid compiler warning.
10317 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10319 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
10320 instead of truncating it to 63 (admittedly a generous limit).
10322 * process.c: Fix spelling and caps in comments.
10324 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
10326 * emacs.c (setpgrp): Remove definition, unused.

10373 Remove unnecessary forward decls.
10375 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
10377 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

10379 * dispnew.c (Fsleep_for, sit_for):
10380 * keyboard.c (kbd_buffer_get_event):
10381 * process.c (Faccept_process_output):
10382 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
10383 This improves on the previous patch, which introduced a bug
10384 when time_t is unsigned and as wide as intmax_t.
10385 See <http://bugs.gnu.org/9000#51>.

10416 language ID in the event parameters.
10418 * w32term.c (w32_read_socket): Put the new keyboard codepage into

10428 * w32.c (fdutimens): New function.
10430 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
10432 * s/ms-w32.h (pselect): Redirect to sys_select.
10434 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
10436 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
10437 in the logic of incrementing and decrementing the value of
10438 use_relocatable_buffers.
10440 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
10442 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
10443 Privately reported by Herbert J. Skuhra.
10444 [__FreeBSD__]: Remove "*/" typo after "#include".
10445 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
10446 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
10447 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
10448 Don't assume EMACS_TIME and struct timeval are the same type.
10450 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
10452 Support higher-resolution time stamps (Bug#9000).
10453 The time stamps are only nanosecond-resolution at the C level,
10454 since that's the best that any real-world system supports now.
10455 But they are picosecond-resolution at the Lisp level, as that's
10456 easy, and leaves room for future OS improvements.
10458 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
10461 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
10462 Don't get current time unless it's needed.
10464 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
10465 now provides it if it's absent.
10466 (start_atimer): Port to higher-res time stamps.
10467 Check for time stamp overflow. Don't get current time more
10468 often than is needed.
10470 * buffer.h (struct buffer): Buffer modtime now has high resolution.
10471 Include systime.h, not time.h.
10472 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
10474 * dired.c: Include stat-time.h.
10475 (Ffile-attributes): File times now have higher resolution.
10477 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
10478 (struct image): Timestamp now has higher resolution.
10480 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
10481 has at least microseconds now. All uses removed.
10482 (update_frame, update_single_window, update_window, update_frame_1)
10483 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
10484 (duration_to_sec_usec): Remove; no longer needed.
10486 * editfns.c (time_overflow): Now extern.
10487 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
10488 (float-time, Fformat_time_string, Fcurrent_time_string)
10489 (Fcurrent_time_zone): Accept and generate higher-resolution
10491 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
10492 (decode_time_components, lisp_seconds_argument): New functions.
10493 (make_time): Now static.
10494 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
10495 Report an error if the time is invalid, rather than having the caller
10498 * fileio.c: Include <stat-time.h>
10499 (Fcopy_file): Copy higher-resolution time stamps.
10500 Prefer to set the time stamp via a file descriptor if that works.
10501 (Fset_file_times, Finsert_file_contents, Fwrite_region)
10502 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
10503 (Fvisited_file_modtime, Fset_visited_file_modtime):
10504 Support higher-resolution time stamps.
10506 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
10508 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
10510 * image.c (prepare_image_for_display, clear_image_cache)
10511 (lookup_image): Port to higer-resolution time stamps.
10513 * keyboard.c (start_polling, bind_polling_period):
10514 Check for time stamp overflow.
10515 (read_char, kbd_buffer_get_event, timer_start_idle)
10516 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
10517 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
10518 Port to higher-resolution time stamps. Do not assume time_t is signed.
10519 (decode_timer): New function. Timers are now vectors of length 9,
10520 not 8, to accommodate the picosecond component.
10521 (timer_check_2): Use it.
10523 * nsterm.m (select_timeout, timeval_subtract): Remove.
10524 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
10525 as they're a bit more accurate and handle overflow better.
10526 (ns_select): Change prototype to be compatible with pselect.
10527 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
10528 * nsterm.h (ns_select): Adjust prototype.
10530 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
10531 us-resolution time stamps.
10532 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
10534 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
10536 * lisp.h (time_overflow): New decl.
10537 (wait_reading_process_output): First arg is now intmax_t, not int,
10538 to accommodate larger waits.
10540 * process.h (struct Lisp_Process.read_output_delay):
10541 Now counts nanoseconds, not microseconds.
10542 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
10544 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
10545 (wait_reading_process_output):
10546 Port to ns-resolution time stamps.
10547 (Faccept_process_output, wait_reading_process_output):
10548 Check for time stamp overflow. Do not assume time_t is signed.
10549 (select_wrapper): Remove; we now use pselect.
10550 (Fprocess_attributes): Now generates ns-resolution time stamps.
10552 * sysdep.c: Include utimens.h. Don't include utime.h
10553 or worry about struct utimbuf; gnulib does that for us now.
10554 (gettimeofday): Remove; gnulib provides a substitute.
10555 (make_timeval): New function.
10556 (set_file_times): Now sets ns-resolution time stamps.
10557 New arg FD; all uses changed.
10558 (time_from_jiffies, ltime_from_jiffies, get_up_time)
10559 (system_process_attributes):
10560 Now returns ns-resolution time stamp. All uses changed.
10561 Check for time stamp overflow.
10563 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
10564 provides a substitute now.
10566 * systime.h: Include timespec.h rather than sys/time.h and time.h,
10567 since it guarantees struct timespec.
10568 (EMACS_TIME): Now struct timespec, so that we can support
10569 ns-resolution time stamps.
10570 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
10571 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
10572 (EMACS_USECS): Remove.
10573 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
10574 so multiply the arg by 1000 before storing it.
10575 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
10577 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
10578 Port to ns-resolution time stamps.
10579 (EMACS_TIME_NEG_P): Remove; replaced by....
10580 (EMACS_TIME_SIGN): New macro.
10581 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
10582 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
10583 (set_file_times, make_time, lisp_time_argument): Adjust signature.
10584 (make_timeval, make_lisp_time, decode_time_components): New decls.
10585 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
10586 that it mishandled time_t overflow. You can't compare by subtracting!
10587 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
10588 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
10590 * term.c: Include <sys/time.h>.
10591 (timeval_to_Time): New function, for proper overflow wraparound.
10592 (term_mouse_position, term_mouse_click): Use it.
10594 * undo.c (record_first_change): Support higher-resolution time stamps
10595 in the undo buffer.
10596 (Fprimitive_undo): Use them when restoring time stamps.
10598 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
10599 (w32_get_internal_run_time):
10600 Port to higher-resolution Emacs time stamps.
10601 (ltime): Now accepts single 64-bit integer, as that's more convenient
10604 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
10606 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
10607 for compatibility with pselect. Support ns-resolution time stamps.
10609 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
10611 * xselect.c (wait_for_property_change, x_get_foreign_selection):
10612 Check for time stamp overflow, and support ns-resolution time stamps.
10614 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
10615 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
10616 (timeval_subtract): Remove; no longer needed.
10617 (XTflash, XTring_bell, x_wait_for_event):
10618 Port to ns-resolution time stamps. Don't assume time_t is signed.
10620 2012-06-22 Chong Yidong <cyd@gnu.org>

10624 2012-06-22 Eli Zaretskii <eliz@gnu.org>
10626 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
10627 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
10628 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
10629 staticidx goes up to 1597 out of 1600 = 0x640.)
10631 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
10633 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
10634 Otherwise, the umask might be mistakenly 0 while handling input signals.
10636 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
10638 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

10644 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
10645 access to `contents' member of Lisp_Vector objects with AREF and ASET
10648 2012-06-19 Chong Yidong <cyd@gnu.org>
10650 * frame.c (delete_frame): When selecting a frame on a different
10651 text terminal, do not alter the terminal's top-frame.
10653 * xdisp.c (format_mode_line_unwind_data): Record the target
10654 frame's selected window and its terminal's top-frame.
10655 (unwind_format_mode_line): Restore them.
10656 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
10658 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
10659 since tty frames can be explicitly named.
10660 (prepare_menu_bars): Likewise.
10662 * term.c (Ftty_top_frame): New function.
10664 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

10667 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
10668 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
10669 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
10670 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
10671 (METER_1, METER_2): Simplify.
10673 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
10675 * data.c (Fdefalias): Return `symbol' (bug#11686).
10677 2012-06-18 Martin Rudalics <rudalics@gmx.at>
10679 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
10680 gets killed during executing of this function (Bug#11665).
10681 Try to always return Qt when the buffer has been actually killed.
10682 (Vkill_buffer_query_functions): In doc-string say that functions
10683 run by this hook should not change the current buffer.
10685 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
10687 Fix recently-introduced process.c problems found by static checking.
10688 * process.c (write_queue_push, write_queue_pop, send_process):
10689 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
10690 (write_queue_pop): Fix pointer signedness problem.
10691 (send_process): Remove unused local.
10693 2012-06-17 Chong Yidong <cyd@gnu.org>
10695 * xdisp.c (redisplay_internal): No need to redisplay terminal
10696 frames that are not on top.

10705 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
10707 * lisp.h (eassert): Assume C89 or later.
10708 This removes the need for CHECK.
10709 (CHECK): Remove. Its comments about always evaluating its
10710 argument were confusing, as 'eassert' typically does not evaluate
10713 * coding.c (produce_chars): Use ptrdiff_t, not int.
10715 * xterm.c (x_draw_underwave): Check for integer overflow.
10716 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
10718 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
10720 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
10721 referenced (Bug#11583).
10723 2012-06-16 Aurelien Aptel <aurelien.aptel@gmail.com>
10725 Implement wave-style variant of underlining.

10870 USE_LISP_UNION_TYPE.
10871 (Fw32_unregister_hot_key): Likewise.
10872 (Fw32_toggle_lock_key): Likewise.
10873 * w32menu.c (add_menu_item): Likewise.
10874 (w32_menu_display_help): Use XIL instead of checking
10875 USE_LISP_UNION_TYPE.
10876 * w32heap.c (allocate_heap): Don't check USE_LISP_UNION_TYPE.
10877 (init_heap): Likewise.
10878 * w32term.c (w32_read_socket): Update comment.
10880 2012-06-13 Glenn Morris <rgm@gnu.org>
10882 * s/usg5-4-common.h, src/s/unixware.h:
10883 Remove define/undef of HAVE_SYSV_SIGPAUSE (not used since 2010-05-04).
10885 * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).
10887 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
10889 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
10890 * alloc.c (make_number) [!defined make_number]:
10891 Remove, as lisp.h always defines this now.
10892 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
10893 (roundup_size): Verify that it is a power of 2.
10894 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
10895 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
10896 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
10897 -DUSE_LSB_TAG=0, to override the automatically-selected default.
10898 USE_LSB_TAG now is always defined to be either 0 or 1.
10900 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
10901 code works fine either way, and efficiency is not a concern here,
10902 as the union type is for debugging, not for production.
10903 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
10904 Use an inline function on all platforms when using the union type,
10905 since this is simpler and 'static inline' can be used portably
10907 (LISP_INITIALLY_ZERO): New macro.
10908 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
10909 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
10911 2012-06-12 Glenn Morris <rgm@gnu.org>

10936 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
10937 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
10938 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
10940 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
10942 * alloc.c (make_byte_code): New function.

10975 2012-06-09 Michael Albinus <michael.albinus@gmx.de>
10977 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
10978 dbus_type_is_basic if available.
10979 (xd_extract_signed, xd_extract_unsigned): Rename from
10980 extract_signed and extract_unsigned, respectively. Adapt callers.

10991 * xdisp.c (vmessage): Treat frame message as multibyte.
10992 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
10993 would generate the diagnostic "Making \302\247 buffer-local while
10996 2012-06-08 Eli Zaretskii <eliz@gnu.org>
10998 * dispnew.c (showing_window_margins_p): Undo last change, which
10999 was done due to an inadvertent commit.
11000 (adjust_frame_glyphs_for_frame_redisplay): Do call
11001 showing_window_margins_p.

11009 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
11011 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
11012 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11014 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11016 * alloc.c (allocate_vectorlike): Fix last change.
11018 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
11020 Block-based vector allocation of small vectors.
11021 * lisp.h (struct vectorlike_header): New field `nbytes',
11022 adjust comment accordingly.
11023 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11024 to denote vector blocks. Adjust users (live_vector_p,
11025 mark_maybe_pointer, valid_lisp_object_p) accordingly.
11026 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
11027 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),

11047 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11049 * doprnt.c (doprnt): Truncate multibyte char correctly.
11050 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11051 would mishandle a string argument "Xc" if X was a multibyte
11052 character of length 2: it would truncate after X's first byte
11053 rather than including all of X.
11055 2012-06-06 Chong Yidong <cyd@gnu.org>
11057 * buffer.c (word_wrap): Doc fix.
11059 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11085 position is past the end of the mode line string.
11087 * buffer.c (buffer_local_value_1): New function, split from
11088 Fbuffer_local_value; can return Qunbound.
11089 (Fbuffer_local_value): Use it.
11090 (Vmode_line_format): Docstring tweaks.
11092 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

11104 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11106 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11107 Convert pctcpu and pctmem to Lisp float properly.
11108 Let the compiler fold better, as 100.0/0x8000 is exact.
11110 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11112 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11115 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

11119 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11121 For a 'struct window', replace some Lisp_Object fields to
11122 bitfields where appropriate, remove unused fields.
11123 * window.h (struct window): Remove unused 'last_mark_x' and
11124 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11125 change its type from Lisp_Object to bitfield.
11126 Change type of 'force_start', 'optional_new_start',
11127 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11128 fields from Lisp_Object to bitfield. Adjust users accordingly.
11130 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11132 Pacify gcc -Wdouble-precision when using Xaw.
11133 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11134 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11135 Use 'float' consistently, rather than 'float' in most places
11136 and 'double' in a couple of places.
11138 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11140 * xdisp.c (handle_stop): Detect whether we have overlay strings
11141 loaded by testing it->current.overlay_string_index to be
11142 non-negative, instead of checking whether n_overlay_strings is
11143 positive. (Bug#11587)
11145 2012-05-31 Chong Yidong <cyd@gnu.org>
11147 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11151 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11153 * search.c (search_buffer): Remove calls to
11154 r_alloc_inhibit_buffer_relocation, as it is now called by
11155 maybe_unify_char, which was the cause of relocation of buffer text
11158 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11160 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11161 for the duration of call to load_charset, to avoid problems with
11162 callers of maybe_unify_char that access buffer text through C
11165 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11166 decrement the inhibition flag, instead of just setting or
11169 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11171 Remove obsolete '#define static' cruft.
11172 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11173 This #undef was "temporary" in 2000; it is no longer needed
11174 now that '#define static' has gone away.
11175 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11176 (gray_bitmap_bits): Remove; no longer needed.
11177 All uses replaced with definiens.

11183 The following changes affect the code only when profiling.
11184 * dispnew.c (__executable_start): Rename from safe_bcopy.
11185 Define only on platforms that need it.
11186 * emacs.c: Include <sys/gmon.h> when profiling.
11187 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
11188 (__executable_start): Remove decl, since lisp.h does it now.
11189 (safe_bcopy): Remove decl; no longer has that name.
11190 (main): Coalesce #if into single bit of code, for simplicity.
11191 Cast pointers to uintptr_t, since standard libraries want integers
11193 * lisp.h (__executable_start): New decl.
11195 2012-05-31 Glenn Morris <rgm@gnu.org>
11197 * image.c (Fimagemagick_types): Doc fix.

11218 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
11220 Do not create empty overlays with the evaporate property (Bug#9642).
11221 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
11222 Bug#9642, but explicitly check that the buffer the overlay would
11223 be moved to is live and rearrange lines to make sure that errors
11224 will not put the overlay in an inconsistent state.
11225 (Fdelete_overlay): Cosmetics.
11227 2012-05-28 Eli Zaretskii <eliz@gnu.org>
11229 * w32term.c (my_bring_window_to_top): New function.
11230 (x_raise_frame): Use handle returned by DeferWindowPos, which
11231 could be different from the original one.

11241 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
11243 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
11244 This avoids undefined behavior that might cause the eassert
11245 to not catch an out-of-range value.
11247 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
11249 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

11261 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
11263 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
11264 Only r_alloc_inhibit_buffer_relocation needed to be added;
11265 the others were already declared.
11267 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
11268 before checking whether it's out of range. Put the check inside
11270 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
11272 2012-05-27 Ken Brown <kbrown@cornell.edu>
11274 * callproc.c (Fcall_process): Restore a line that was accidentally
11275 commented out in the 2011-02-13 change (bug#11547).

11279 * lisp.h [REL_ALLOC]: Add prototypes for external functions
11280 defined on ralloc.c.
11282 * buffer.c [REL_ALLOC]: Remove prototypes of
11283 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
11284 they are now on lisp.h.
11286 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
11288 * search.c (search_buffer): Use it to inhibit relocation of buffer
11289 text while re_search_2 is doing its job, because re_search_2 is
11290 passed C pointers to buffer text. (Bug#11519)
11292 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
11293 Update value to 24.
11295 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
11296 state after an additional call to move_it_in_display_line_to, keep
11297 the values of it->max_ascent and it->max_descent found for the
11299 (pos_visible_p): Revert the comparison against bottom_y to what it
11300 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
11303 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11305 Fix coding-related core dumps with gcc -ftrapv.
11306 The code was computing A - B, where A and B are pointers, and B is
11307 random garbage. This can lead to core dumps on platforms that
11308 have special pointer registers, and it also leads to core dumps on
11309 x86-64 when compiled with gcc -ftrapv. The fix is to compute
11310 A - B only when B is initialized properly.
11311 * coding.c (coding_set_source, coding_set_destination): Return void.
11312 (coding_change_source, coding_change_destinations): New functions,
11313 with the old behaviors of coding_set_source and coding_set_destination.
11314 All callers that need an offset changed to use these new functions.
11316 2012-05-26 Glenn Morris <rgm@gnu.org>
11318 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)

11333 moves, call note_mouse_highlight. If help_echo changed, call
11334 gen_help_event to produce help-echo message in the echo area.
11335 Call clear_mouse_face if mouse_face_hidden is set in the mouse
11338 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
11340 * lread.c (read1): Simplify slightly to avoid an overflow warning
11341 with GCC 4.7.0 on x86-64.
11343 2012-05-26 Eli Zaretskii <eliz@gnu.org>
11345 * bidi.c (bidi_mirror_char): Revert last change: an int is
11346 definitely wide enough here.
11348 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

11362 Use int, not EMACS_INT, where int is wide enough.
11363 (inhibit_garbage_collection, Fgarbage_collect):
11364 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11365 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
11366 int might not be wide enough.

11382 (Foverlay_recenter, last_overlay_modification_hooks_used)
11383 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
11384 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11385 (validate_region): Omit unnecessary test for b <= e,
11386 since that's guaranteed by the previous test.
11387 (adjust_overlays_for_delete): Avoid pos + length overflow.
11388 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
11389 (report_overlay_modification):
11390 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11391 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
11392 Omit pointer cast, which isn't needed anyway, and doesn't work
11393 after the EMACS_INT -> ptrdiff_t change.
11394 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
11395 * buffer.h: Adjust decls to match defn changes elsewhere.

11400 not int, to avoid needless 32-bit limit on 64-bit hosts.
11401 (exec_byte_code): Use tighter memory-full test, one that checks
11402 for alloca overflow. Don't compute the address of the object just
11403 before an array, as that's not portable. Use EMACS_INT, not
11404 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
11405 * callint.c (Fcall_interactively):
11406 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
11407 * callproc.c (call_process_kill, Fcall_process):
11408 Don't assume pid_t fits into an Emacs fixnum.

11418 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11419 (casify_object): Avoid integer overflow when overallocating buffer.
11420 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
11421 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.

11423 * category.h (CATEGORYP): Don't assume arg is nonnegative.
11424 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
11425 integers are now checked earlier. All uses replaced with XINT.
11427 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11428 For CCL_MapSingle, check that content and value are in int range.
11429 (ccl_driver, Fregister_code_conversion_map):
11430 Check that Vcode_version_map_vector is a vector.
11431 (resolve_symbol_ccl_program): Check that vector header is in range.
11432 Always copy the vector, so that we can check its contents reliably
11433 now rather than having to recheck each instruction as it's being
11434 executed. Check that vector words fit in 'int'.
11435 (ccl_get_compiled_code, Fregister_ccl_program)
11436 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
11437 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
11438 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
11439 contents are in range.
11440 (Fccl_execute_on_string): Check that status is in range.
11441 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
11442 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
11443 Accept and return EMACS_INT, not int, because callers can pass values
11444 out of 'int' range.

11450 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
11451 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
11452 avoid mishandling large integers.

11459 Don't assume fixnum fits in int.

11461 Remove now-unnecessary CHECK_NATNUMs.
11462 (Fdefine_charset_internal): Check ranges here, more carefully.
11463 Don't rely on undefined behavior with signed left shift overflow.
11464 Don't assume unsigned int fits into fixnum, or that fixnum fits
11465 into unsigned int. Don't require max_code to be a valid fixnum;
11466 that's not true for gb10830 4-byte on a 32-bit host. Allow
11467 invalid_code to be a cons, for the same reason. Require code_offset
11468 to be a character. Avoid int overflow if max_char is close
11470 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
11471 this is intended anyway and avoids some undefined behavior.
11472 (load_charset_map): Pass unsigned, not int, as 2nd arg of
11473 INDEX_TO_CODE_POINT, as that's what it expects.
11474 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
11475 * charset.h (DECODE_CHAR): Return int, not unsigned;
11476 this is what was intended anyway, and it avoids undefined behavior.
11477 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
11478 integer-overflow issues.
11479 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
11480 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
11481 where the argument is EMACS_INT, and this behavior is not intended.
11482 * chartab.c (Fmake_char_table, Fset_char_table_range)
11483 (uniprop_get_decoder, uniprop_get_encoder):
11484 Don't assume fixnum fits in int.
11485 * cmds.c (move_point): New function, that does the gist of
11486 Fforward_char and Fbackward_char, but does so while checking
11487 for integer overflow more accurately.
11488 (Fforward_char, Fbackward_char): Use it.
11489 (Fforward_line, Fend_of_line, internal_self_insert)
11490 (internal_self_insert):
11491 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12260 (Fword_search_forward, Fword_search_backward_lax)
12261 (Fword_search_forward_lax): Move functions to isearch.el
12262 (bug#10145, bug#11381).
12264 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
12266 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
12268 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
12270 * lread.c (init_obarray): Declare Qt and Qnil as special.
12272 2012-05-14 Glenn Morris <rgm@gnu.org>
12274 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
12275 Put "libexec" before "bin", for the sake of init_callproc_1.
12277 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12279 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
12281 * unexaix.c: Port to more-recent AIX compilers.
12282 (report_error, report_error_1, make_hdr, copy_sym)
12283 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
12284 Make arguments const char *, not char *, to avoid violations of C
12285 standard and to fix some AIX warnings reported by Gilles Pion.
12287 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12289 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
12290 already have overlays loaded.
12291 (handle_single_display_spec): Before returning without displaying
12292 fringe bitmap, synchronize the bidi iterator with the main display
12293 iterator, by calling iterate_out_of_display_property.
12294 (iterate_out_of_display_property): Detect buffer iteration by
12295 testing that it->string is a Lisp string.
12296 (get_next_display_element): When the current object is exhausted,
12297 and there's something on it->stack, call set_iterator_to_next to
12298 proceed with what's on the stack, instead of returning zero.
12299 (set_iterator_to_next): If called at the end of a Lisp string,
12300 proceed to consider_string_end without incrementing string
12301 position. Don't increment display vector index past the end of
12302 the display vector. (Bug#11417)
12303 (pos_visible_p): Don't report a position visible when move_it_to
12304 stopped at the last line of window, which happens to be scanned
12305 backwards by the bidi iteration. (Bug#11464)
12307 2012-05-14 Eli Zaretskii <eliz@gnu.org>
12309 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
12310 and right-margin display specs even if the spec is invalid or we
12311 are on a TTY, and thus unable to display on the fringes.
12312 That's because the text with the property will not be displayed anyway,
12313 so we need to signal to the caller that this is a "replacing"
12314 display spec. This fixes display when the spec is invalid or we
12317 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
12319 * unexaix.c (make_hdr): Fix typo in prototype.
12320 This bug broke the build on AIX. Problem reported by Gilles Pion.
12322 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
12324 * keyboard.c (kbd_buffer_get_event): Read special events also in
12325 batch mode. (Bug#11415)
12327 2012-05-12 Glenn Morris <rgm@gnu.org>

12335 2012-05-12 Glenn Morris <rgm@gnu.org>
12337 * Makefile.in (MKDIR_P): New, set by configure.
12338 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
12340 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>

12350 Update dependencies.
12352 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
12354 * xgselect.c (xg_select): Put maxfds+1 into a var.
12355 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
12357 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
12359 2012-05-10 Dave Abrahams <dave@boostpro.com>
12361 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
12362 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
12364 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
12366 * dbusbind.c (xd_registered_buses): New internal Lisp object.
12367 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
12368 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
12369 Initialize xd_registered_buses.
12371 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
12373 Untag more efficiently if USE_LSB_TAG.
12374 This is based on a proposal by YAMAMOTO Mitsuharu in
12375 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
12376 For an admittedly artificial (nth 8000 longlist) benchmark on
12377 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
12378 Emacs's overall text size by 1%.
12379 * lisp.h (XUNTAG): New macro.
12380 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
12381 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
12382 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
12383 * eval.c (Fautoload):
12384 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
12385 * frame.h (XFRAME): Use XUNTAG.
12387 Port recent dbusbind.c changes to 32-bit --with-wide-int.
12388 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
12389 Remove unportable assumptions about print widths of types like
12391 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
12392 intptr_t when converting between pointer and integer, to avoid GCC
12393 warnings about wrong width.
12395 2012-05-09 Eli Zaretskii <eliz@gnu.org>
12397 * w32proc.c (new_child): Force Windows to reserve only 64KB of
12398 stack for each reader_thread, instead of defaulting to 8MB
12399 determined by the linker. This avoids failures in creating
12400 subprocesses on Windows 7, see the discussion in this thread:
12401 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
12403 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
12405 Fix up display of the *Minibuf-0* buffer in the mini window.
12406 * keyboard.c (read_char): Don't clear the echo area if there's no
12408 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
12409 contents of *Minibuf-0*) if there's no message displayed in its stead.
12411 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
12413 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
12416 2012-05-06 Chong Yidong <cyd@gnu.org>
12418 * lisp.mk (lisp): Update.
12420 2012-05-05 Jim Meyering <meyering@redhat.com>
12422 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
12424 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
12426 * data.c (PUT_ERROR): New macro.
12427 (syms_of_data): Use it. Add new error type `user-error'.
12428 * undo.c (user_error): New function.
12429 (Fprimitive_undo): Use it.
12430 * print.c (print_error_message): Adjust print style for `user-error'.
12431 * keyboard.c (user_error): New function.
12432 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
12434 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
12436 Do not limit current-time-string to years 1000..9999.
12437 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
12438 (Fcurrent_time_string): Support any year that is supported by the
12439 underlying localtime representation. Don't use asctime, as it
12440 has undefined behavior for years outside the range -999..9999.
12442 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
12444 Fix race conditions involving setenv, gmtime, localtime, asctime.
12445 Without this fix, interrupts could mess up code that uses these
12446 nonreentrant functions, since setting TZ invalidates existing
12447 tm_zone or tzname values, and since most of these functions return
12448 pointers to static storage.
12449 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
12450 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
12451 Grow the critical sections to include not just invoking
12452 localtime/gmtime, but also accessing these functions' results
12453 including their tm_zone values if any, and any related TZ setting.
12454 (format_time_string): Last arg is now struct tm *, not struct tm **,
12455 so that the struct tm is saved in the critical section.
12456 All callers changed. Simplify allocation of initial buffer, partly
12457 motivated by the fact that memory allocation needs to be outside
12458 the critical section.
12460 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
12462 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
12463 with RESET_INTERVAL.
12465 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
12466 Remove duplicated buffer name initialization.
12468 2012-05-02 Jim Meyering <jim@meyering.net>
12470 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
12472 * xfns.c (x_window): Use xstrdup (Bug#11375).
12474 2012-05-02 Eli Zaretskii <eliz@gnu.org>
12476 * xdisp.c (pos_visible_p): If already at a newline from the
12477 display string before the 'while' loop, don't walk back the glyphs
12478 from it3.glyph_row. Solves assertion violation when the display
12479 string begins with a newline (egg.el). (Bug#11367)
12481 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
12483 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
12486 2012-05-01 Glenn Morris <rgm@gnu.org>
12488 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
12489 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
12490 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
12491 All were removed before 23.1.
12493 * dispnew.c: Remove HAVE_LIBNCURSES test;
12494 it is always true on relevant platforms.
12496 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
12497 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
12499 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
12501 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
12503 * .gdbinit (xpr): Remove checks for no longer existing misc types.
12504 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
12507 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
12509 Do not avoid creating empty evaporating overlays (Bug#9642).
12510 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
12511 That is, do not delete an evaporating overlay if it becomes
12512 empty after its bounds are adjusted to fit within its buffer.
12513 This fix caused other problems, and I'm reverting it until we get
12514 to the bottom of them.
12516 2012-04-27 Chong Yidong <cyd@gnu.org>
12518 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
12520 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12522 * xdisp.c (pos_visible_p): If the window start position is beyond
12523 ZV, start the display from buffer beginning. Prevents assertion
12524 violation in init_iterator when the minibuffer window is scrolled
12525 via the scroll bar.
12527 * window.c (window_scroll_pixel_based): Likewise.
12529 2012-04-27 Chong Yidong <cyd@gnu.org>
12531 * keymap.c (where_is_internal): Doc fix (Bug#10872).
12533 2012-04-27 Glenn Morris <rgm@gnu.org>
12535 * fileio.c (Fcopy_file, Fset_file_selinux_context):
12536 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
12538 2012-04-27 Eli Zaretskii <eliz@gnu.org>
12540 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
12541 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
12543 2012-04-26 Eli Zaretskii <eliz@gnu.org>
12545 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
12546 display element, check also the underlying string or buffer
12547 character. (Bug#11341)
12549 * w32menu.c: Include w32heap.h.
12550 (add_menu_item): If the call to AppendMenuW (via
12551 unicode_append_menu) fails, disable Unicode menus only if we are
12552 running on Windows 9X/Me.
12554 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
12556 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
12557 (xgetint): Add missing shift for LSB tags.
12559 2012-04-24 Martin Rudalics <rudalics@gmx.at>
12561 * keyboard.c (read_char): Don't wipe echo area for select window
12562 events: These might get delayed via `mouse-autoselect-window'
12565 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
12567 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
12568 manipulation of :loaded-from data.
12570 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
12572 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
12573 now a cons (bug#11311).
12575 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
12577 Do not create empty overlays with the evaporate property (Bug#9642).
12578 * buffer.c (Fmove_overlay): Delete an evaporating overlay
12579 if it becomes empty after its bounds are adjusted to fit within
12580 its buffer. Without this fix, in a nonempty buffer (let ((o
12581 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
12582 yields an empty overlay that has the evaporate property, which is
12583 not supposed to happen.
12585 Fix minor GTK3 problems found by static checking.
12586 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

12603 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
12605 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
12606 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
12607 (__malloc_size_t, __malloc_ptrdiff_t):
12608 Remove. All uses removed, replaced by the definiens if needed,
12609 since we can assume C89 or better now.
12610 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

12618 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
12619 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
12620 Define using prototypes, not old style.

12685 * alloc.c: Handle unusual debugging option combinations.
12686 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
12687 since the two debugging options are incompatible.
12688 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

12742 row, return zero immediately.
12743 (try_cursor_movement): If inside continuation line, don't back up
12744 farther than the first row after the header line, if any.
12745 Don't consider the header-line row as "partially visible", even if

12794 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
12795 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
12796 (r_alloc_sbrk): Now static.
12798 Improve ralloc.c interface checking.
12799 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
12800 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

12822 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
12824 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
12825 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
12826 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
12827 * s/netbsd.h, s/sol2-6.h:
12828 Remove definition of GC_MARK_STACK, since the default now works.
12829 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
12830 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
12831 no longer the default.
12832 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
12834 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
12836 * lread.c (lisp_file_lexically_bound_p):
12837 Fix hang at ";-*-\n" (bug#11238).
12839 2012-04-14 Eli Zaretskii <eliz@gnu.org>
12841 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
12842 "unchanged" if its end.pos is beyond ZV. (Bug#11199)
12844 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
12846 * nsterm.m (constrainFrameRect): Always constrain when there is only
12847 one screen (Bug#10962).
12849 2012-04-13 Ken Brown <kbrown@cornell.edu>
12851 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
12853 2012-04-13 Reuben Thomas <rrt@sc3d.org>
12855 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
12857 2012-04-11 Daniel Colascione <dancol@dancol.org>
12859 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
12860 against is gone. It's better to use vfork now so that when Cygwin
12861 gains a new, working vfork, we use it automatically (bug#10398).
12863 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
12865 * window.c (save_window_save): Obey window-point-insertion-type.
12867 2012-04-11 Glenn Morris <rgm@gnu.org>
12869 * Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.

12877 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
12878 (force_quit_count): New var.
12879 (handle_interrupt): Use it.
12881 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
12883 * w32.c (w32_delayed_load): Record the full path of the library
12884 being loaded (bug#10424).
12886 2012-04-09 Glenn Morris <rgm@gnu.org>
12888 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
12889 not just in the obarray, before snarfing them. (Bug#11036)
12891 * Makefile.in ($(leimdir)/leim-list.el):
12892 Pass EMACS rather than BUILT_EMACS.
12894 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
12896 * process.c (make_process):
12897 * process.h: Add integer `gnutls_handshakes_tried' member to
12900 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
12901 Add convenience `GNUTLS_LOG2i' macro.
12903 * gnutls.c (gnutls_log_function2i): Convenience log function.
12904 (emacs_gnutls_read): Use new log functions,
12905 `gnutls_handshakes_tried' process member, and
12906 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
12907 attempts per process (connection).
12909 2012-04-09 Chong Yidong <cyd@gnu.org>
12911 * eval.c (Fuser_variable_p, user_variable_p_eh)
12912 (lisp_indirect_variable): Functions deleted.
12913 (Fdefvar): Caller changed.
12915 * callint.c (Finteractive, Fcall_interactively):
12916 * minibuf.c (Fread_variable): Callers changed.
12918 2012-04-09 Eli Zaretskii <eliz@gnu.org>
12920 * xdisp.c (set_cursor_from_row): If the display string appears in
12921 the buffer at position that is closer to point than the position
12922 after the display string, display the cursor on the first glyph of
12923 the display string. Fixes cursor display when a 'display' text
12924 property immediately follows invisible text. (Bug#11094)
12926 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
12928 composite.c: use 'double' consistently
12929 * composite.c (get_composition_id): Use 'double' consistently
12930 instead of converting 'float' to 'double' and vice versa; this is
12931 easier to understand and avoids a GCC warning.
12933 2012-04-09 Glenn Morris <rgm@gnu.org>
12935 * Makefile.in: Generate leim-list with bootstrap-emacs, in
12936 preparation for dumping it with emacs. (Bug#4789)
12937 (leimdir): New variable.
12938 ($(leimdir)/leim-list.el): New rule.
12939 (emacs$(EXEEXT)): Depend on leim-list.el.
12941 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
12942 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
12943 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
12945 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
12947 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
12950 2012-04-07 Juanma Barranquero <lekktu@gmail.com>
12952 * xml.c (init_libxml2_functions) [WINDOWSNT]:
12953 Remove unused local variable.
12955 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12957 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
12958 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
12959 (mark_memory): Mark Lisp_Objects only if pointers might hide in
12960 objects, as mark_maybe_pointer will catch them otherwise.
12961 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
12962 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
12964 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
12966 Fix typo that broke non-Windows builds.
12967 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
12969 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12971 Support building on MS-Windows with libxml2.
12973 * makefile.w32-in (OBJ2): Add xml.$(O).
12974 (GLOBAL_SOURCES): Add xml.c.
12975 ($(BLD)/xml.$(O)): New dependency list.
12977 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
12978 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
12979 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
12980 [!WINDOWSNT]: New macros.
12981 (init_libxml2_functions, libxml2_loaded_p): New functions.
12982 (parse_region): Call fn_xmlCheckVersion instead of using the macro
12983 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
12984 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
12985 Calls xmlCleanupParser only if libxml2 was loaded (or statically
12987 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
12988 Call init_libxml2_functions before calling libxml2 functions.
12989 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
12991 * emacs.c: Don't include libxml/parser.h.
12992 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
12993 xmlCleanupParser directly.
12995 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
12997 2012-04-07 Eli Zaretskii <eliz@gnu.org>
12999 * indent.c (Fvertical_motion): If there is a display string at
13000 point, use it.vpos to compute how many lines to backtrack after
13001 move_it_to point. (Bug#11133)
13003 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13005 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13006 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13007 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13008 macros related to unification of CJK characters. For the details,
13009 see the discussion following the message here:
13010 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13012 2012-04-04 Chong Yidong <cyd@gnu.org>
13014 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13016 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13018 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13019 instead of alloca. (Bug#11138)
13021 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13023 * w32menu.c (is_simple_dialog): Properly check lisp types.
13026 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13028 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13029 position we get to after a call to move_it_to fails the
13030 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13031 only if we wind up in a string from display property. (Bug#11063)
13033 * window.c (Fdelete_other_windows_internal): Invalidate the row
13034 and column information about mouse highlight, so that redisplay
13035 restores it after reallocating the glyph matrices. (Bug#7464)
13037 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13038 string comes from a `display' text property, use the buffer
13039 position of that property as if we actually saw that position in
13041 (move_it_by_lines): Remove the assertion that
13042 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13043 violated when there's a before-string at the beginning of a line.
13046 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13048 * xdisp.c (append_space_for_newline): If the default face was
13049 remapped, use the remapped face for the appended newline.
13050 (extend_face_to_end_of_line): Use the remapped default face for
13051 extending the face to the end of the line.
13052 (display_line): Call extend_face_to_end_of_line when the default
13053 face was remapped. (Bug#11068)
13055 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13057 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13059 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13061 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13063 2012-03-27 Glenn Morris <rgm@gnu.org>
13065 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13068 2012-03-26 Kenichi Handa <handa@m17n.org>
13070 * dispextern.h (struct glyph): Fix previous change. Change the
13071 bit length of glyphless.ch to 25 (Bug#11082).
13073 2012-03-26 Chong Yidong <cyd@gnu.org>
13075 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13076 (command_loop_1): Use it; inhibit selection update for
13077 handle-select-window too (Bug#8996).
13079 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13081 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13083 2012-03-25 Kenichi Handa <handa@m17n.org>
13085 * dispextern.h (struct glyph): Change the bit length of
13086 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13088 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13090 * s/ms-w32.h (tzname): Include time.h before redirecting to
13091 _tzname. Fixes the MSVC build. (Bug#9960)
13093 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13095 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13098 * xterm.c (XTread_socket): Only modify handling_signal if
13099 !SYNC_INPUT. (Bug#11080)
13101 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13103 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13104 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13105 when fetching a multibyte character consumes more bytes than
13106 CHAR_BYTES returns, due to unification of CJK characters in
13107 string_char. (Bug#11073)
13109 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13111 * process.c (wait_reading_process_output): Handle pty disconnect
13112 by refraining from sending oneself a SIGCHLD (bug#10933).
13114 2012-03-22 Chong Yidong <cyd@gnu.org>
13116 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13118 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13119 Mark string as coming from a prefix property.
13120 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13121 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13123 2012-03-21 Chong Yidong <cyd@gnu.org>
13125 * xfaces.c (Vface_remapping_alist): Doc fix.
13127 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13129 * w32proc.c (Fw32_set_console_codepage)
13130 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13133 2012-03-20 Chong Yidong <cyd@gnu.org>
13135 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13136 to reflect default non-nil value of redisplay-dont-pause.
13138 2012-03-19 Kenichi Handa <handa@m17n.org>
13140 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13141 it fit in a valid range (Bug#11003).
13143 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13145 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13146 that is not from display property, accept the row as a "cursor
13147 row" if one of the string's character has a non-nil `cursor'
13148 property. Fixes cursor positioning when there are newlines in
13149 overlay strings, e.g. in icomplete.el. (Bug#11035)
13151 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13153 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13155 2012-03-12 Chong Yidong <cyd@gnu.org>
13157 * eval.c (inhibit_lisp_code): Rename from
13158 inhibit_window_configuration_change_hook; move from window.c.
13160 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13161 * window.c (run_window_configuration_change_hook)
13162 (syms_of_window): Callers changed.
13164 2012-03-11 Chong Yidong <cyd@gnu.org>
13166 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13168 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13170 2012-03-10 Chong Yidong <cyd@gnu.org>
13172 * frame.c (other_visible_frames): Don't assume the selected frame
13173 is visible (Bug#10955).
13175 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13177 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
13179 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
13181 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
13182 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
13185 2012-03-03 Glenn Morris <rgm@gnu.org>
13187 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
13189 2012-03-02 Eli Zaretskii <eliz@gnu.org>
13191 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
13192 position past the first glyph_row that ends at ZV. (Bug#10902)
13193 (redisplay_window, next_element_from_string): Fix typos in
13195 (redisplay_window): Pass to move_it_vertically the margin in
13196 pixels, not in screen lines.
13198 2012-03-02 Glenn Morris <rgm@gnu.org>
13200 * buffer.c (buffer-list-update-hook): Doc fix.
13202 2012-02-29 Eli Zaretskii <eliz@gnu.org>
13204 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
13205 push_it before setting up the iterator for the first overlay
13206 string, even if we have an empty string loaded.
13207 (next_overlay_string): If there's an empty string on the iterator
13208 stack, pop the stack. (Bug#10903)
13210 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
13212 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
13213 Suggested by Stefan Monnier in
13214 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
13215 * alloc.c (widen_to_Lisp_Object): New static function.
13216 (mark_memory): Also mark Lisp_Objects by fetching pointer words
13217 and widening them to Lisp_Objects. This would work even if
13218 USE_LSB_TAG is defined and wide integers are used, which might
13219 happen in a future version of Emacs.
13221 2012-02-25 Chong Yidong <cyd@gnu.org>
13223 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
13226 * xselect.c (Fx_selection_exists_p): Doc fix.
13227 (x_clipboard_manager_save_all): Print an informative message
13228 before saving to clipboard manager.
13230 2012-02-24 Chong Yidong <cyd@gnu.org>
13232 * keyboard.c (process_special_events): Handle all X selection
13233 requests in kbd_buffer, not just the next one (Bug#8869).
13235 2012-02-23 Chong Yidong <cyd@gnu.org>
13237 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
13238 call when setting menu-bar-lines and tool-bar-lines parameters.
13239 (unwind_create_frame_1): New helper function.
13241 * window.c (inhibit_window_configuration_change_hook): New var.
13242 (run_window_configuration_change_hook): Obey it.
13243 (syms_of_window): Initialize it.
13245 2012-02-22 Chong Yidong <cyd@gnu.org>
13247 * xterm.c (x_draw_image_relief): Add missing type check for
13248 Vtool_bar_button_margin (Bug#10743).
13250 2012-02-21 Chong Yidong <cyd@gnu.org>
13252 * fileio.c (Vfile_name_handler_alist): Doc fix.
13254 * buffer.c (Fget_file_buffer): Protect against invalid file
13255 handler return value.
13257 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
13259 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
13260 when computing $valmask.
13262 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
13263 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
13264 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
13265 It's useless in that case, and it can cause problems on hosts
13266 that allocate halves of EMACS_INT values separately.
13267 Reported by Dan Horák. Diagnosed by Andreas Schwab in
13268 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
13269 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
13270 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
13271 it avoids undefined behavior on hosts where shifting right by more
13272 than the word width has undefined behavior.
13274 2012-02-19 Chong Yidong <cyd@gnu.org>
13276 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
13277 (Funhandled_file_name_directory, Ffile_name_as_directory)
13278 (Fdirectory_file_name, Fexpand_file_name)
13279 (Fsubstitute_in_file_name): Protect against invalid file handler
13280 return values (Bug#10845).
13282 2012-02-18 Eli Zaretskii <eliz@gnu.org>
13284 * .gdbinit (pitx): Fix incorrect references to fields of the
13287 2012-02-17 Chong Yidong <cyd@gnu.org>

13889 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
13890 verifies glyph row's hash code--we have just reallocated the

14056 is set, removing the need for VIRT_ADDRESS_VARIES.
14057 (PURE_P): Use a more-efficient implementation that needs just one

14064 consistency with the new puresize.h.
14065 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14066 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14074 behave as if the cursor position were at the window margin.
14076 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14077 and the cursor position is out of bounds, behave as if the cursor
14078 position were at the window margin. (Bug#10075)
14080 2011-11-18 Chong Yidong <cyd@gnu.org>
14082 * window.c (Fwindow_combination_limit): Make first argument

14104 compute_line_metrics.
14105 (compute_line_metrics): Call row_hash, instead of computing the
14108 * dispnew.c (verify_row_hash): Call row_hash for computing the
14109 hash code of a row, instead of duplicating code from xdisp.c.
14111 * dispextern.h (row_hash): Add prototype.
14113 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

14164 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14165 with user-defined heap size. Bump the default size of the temacs

14169 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14170 current_matrix and desired_matrix. (Bug#9990)
14171 (verify_row_hash) [XASSERTS]: New function.

14216 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
14218 Avoid some portability problems by eschewing 'extern inline' functions.
14219 The trivial performance wins aren't worth the portability hassles; see
14220 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
14222 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

14263 (Fdelete_other_windows_internal, Fset_window_configuration):
14264 Call delete_all_child_windows instead of delete_all_subwindows.
14265 * frame.c (delete_frame): Call delete_all_child_windows instead

14270 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
14271 This is also needed for porting to any host where GC_MARK_STACK is
14272 not GC_MAKE_GCPROS_NOOPS.
14273 (which_symbols): Use it.
14275 2011-11-07 Kenichi Handa <handa@m17n.org>
14277 * coding.c (coding_set_destination): Check coding->src_pos only
14278 when coding->src_object is a buffer (bug#9910).

14288 * xmenu.c (cleanup_widget_value_tree): New function.
14289 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
14290 calling free_menubar_widget_value_tree directly (Bug#9830).
14292 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
14294 Fix some portability problems with 'inline'.

14296 (window_box_width, window_box_left, window_box_left_offset)
14297 (window_box_right, window_box_right_offset): Declare extern.
14298 Otherwise, these inline functions do not conform to C99 and
14299 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
14300 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
14301 * intervals.c (adjust_intervals_for_insertion)
14302 (adjust_intervals_for_deletion): Now extern, because otherwise the

14304 (static_offset_intervals): Remove.
14305 (offset_intervals): Rewrite using the old contents of
14306 static_offset_intervals. The old version didn't conform to C99
14307 because an extern inline function contained a reference to an
14308 identifier with static linkage.
14310 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
14312 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

14330 (Fwindow_vscroll): Doc fix.
14331 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
14332 argument, since it makes no sense to pass a live window and for
14333 consistency with window-child.

14361 (unwind_create_frame): New function (Bug#9943).
14362 (Fx_create_frame): Restructure code to be more similar to the one in
14363 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).

14374 official. Move initialization of image_cache_refcount and
14375 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

14415 previous/next-single-property-change returns nil, treat that as
14416 the beginning or the end of the buffer. (Bug#9955)
14418 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
14420 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

14452 2011-10-30 Eli Zaretskii <eliz@gnu.org>
14454 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
14455 past the beginning of the current glyph matrix.
14457 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
14459 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

14543 (w32font_open_internal, compute_metrics):
14544 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
14545 instead of calling the "wide" APIs directly.

14549 * w32.h (syms_of_w32font): Add prototype.
14551 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

14558 2011-10-27 Chong Yidong <cyd@gnu.org>
14560 * process.c (make_process): Set gnutls_state to NULL.
14562 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
14563 non-NULL, regardless of GNUTLS_INITSTAGE.

14612 (bidi_resolve_weak): Don't enter the expensive loop if the current
14613 position is before next_en_pos. Record the bidi type of the first
14614 non-ET, non-BN character we find, in addition to its position.
14615 (bidi_level_of_next_char): Invalidate next_en_type when
14616 next_en_pos is over-stepped.
14618 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
14620 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
14621 * editfns.c: Rewrite current-time-zone so that it invokes
14622 the equivalent of (format-time-string "%Z") to get the time zone name.
14623 This fixes a bug when the time zone name contains characters that
14624 need converting from the system time locale to Emacs internal format.
14625 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
14626 that patch fixed format-time-string to do the conversion, but
14627 I forgot to fix current-time-zone.
14628 (format_time_string): New function, containing most of
14629 what Fformat_time_string used to contain.
14630 (Fformat_time_string): Rewrite in terms of format_time_string.
14631 This doesn't change this function's behavior.
14632 (current-time-zone): Rewrite to use format_time_string.
14633 This fixes the bug reported by Michael Schierl in
14634 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
14635 Jason Rumney's 2007-06-07 change worked around this bug, but
14637 * systime.h (tzname, timezone): Remove no-longer-used declarations.
14639 2011-10-19 Eli Zaretskii <eliz@gnu.org>
14641 * xdisp.c (start_display): If the character at POS is displayed
14642 via a display vector, reset IT->current.dpvec_index to zero.
14643 (try_window_reusing_current_matrix): If a line ends in a display
14644 vector or the next line starts in a display vector, continue
14645 redrawing the window even though the character position of
14646 start_row was reached.
14649 2011-10-18 Chong Yidong <cyd@gnu.org>
14651 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
14652 with nobreak-char-display too.
14654 2011-10-18 Eli Zaretskii <eliz@gnu.org>
14656 Fix part 3 of bug#9771.
14657 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
14658 (bidi_resolve_neutral): Don't enter the expensive loop looking for
14659 non-neutral characters if the current character is a paragraph
14660 separator (a.k.a. Newline). This avoids running the same
14661 expensive loop twice, once when we consume the preceding newline
14662 and the other time when the line actually needs to be displayed.
14663 Avoid the loop when we see neutrals on the base embedding level
14664 following a character whose directionality is the same as the
14665 paragraph's. This avoids running the expensive loop when a line
14666 ends in a long sequence of neutrals, like control characters.
14667 Add assertion against STRONG_AL type. Slightly rearrange code
14668 that determines the type of a neutral given the first non-neutral
14670 (bidi_level_of_next_char): Set next_en_pos to zero when
14671 invalidating its info.
14673 2011-10-17 Eli Zaretskii <eliz@gnu.org>
14675 * xdisp.c (push_display_prop): Determine whether to record string
14676 or buffer position by IT->string, not by IT->method. Allow
14677 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
14678 (move_it_vertically_backward): Don't look for character position
14679 immediately after the newline when in a continuation line.
14682 2011-10-15 Martin Rudalics <rudalics@gmx.at>
14684 * window.c (coordinates_in_window): Rewrite and delabelize
14685 vertical border check. (Bug#5357) (Bug#9618)
14687 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
14689 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
14690 errors in XSetWindowBorder (bug#9310).
14692 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
14694 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
14695 avoid crash when xmalloc overrun checking is enabled.
14697 2011-10-13 Eli Zaretskii <eliz@gnu.org>
14699 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
14700 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
14701 cursor motion with <left> and <right> arrow keys.
14703 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
14704 some callers set that themselves.
14706 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14708 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
14709 display string and the previous row comes from the same string and
14710 is empty. (Bug#9739) (Bug#9738)
14712 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
14714 * doc.c (get_doc_string): Encode file name (bug#9735).
14716 2011-10-12 Eli Zaretskii <eliz@gnu.org>
14718 * bidi.c (bidi_level_of_next_char):
14719 * xdisp.c (get_visually_first_element): Remove old incorrect
14720 comments regarding the Unicode Line Separator character.
14722 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
14724 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
14726 * alloc.c (Fgc_status): Do not access beyond zombies array
14727 boundary if nzombies > MAX_ZOMBIES.
14728 * alloc.c (dump_zombies): Add missing format specifier.
14730 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
14732 * xdisp.c (set_cursor_from_row): Simplify conditionals,
14733 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
14735 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
14736 Some packages use them to denote characters with modifiers.
14738 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
14740 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
14741 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
14742 matching a pp-number. Rename parameter var to var1.
14744 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
14746 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
14748 2011-10-08 Glenn Morris <rgm@gnu.org>
14750 * callint.c (Fcall_interactively): Give a more explicit error for the
14751 'c' case with a non-character input. (Bug#8479)
14753 2011-10-08 Eli Zaretskii <eliz@gnu.org>
14755 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
14757 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
14758 lines that are hscrolled on the left.
14760 * dispnew.c (buffer_posn_from_coords): Account for a possible
14761 presence of header-line. (Bug#4426)
14763 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
14765 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
14766 Don't advertise functionality which we discourage or doesn't work.
14768 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
14770 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
14771 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
14772 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
14773 this makes Emacs dump core during garbage collection on rare
14774 occasions. sizeof is obviously inferior to offsetof here, so
14775 stick with offsetof.
14776 (GC_POINTER_ALIGNMENT): New macro.
14777 (mark_memory): Omit 3rd (offset) arg; caller changed.
14778 Don't assume EMACS_INT alignment is the same as pointer alignment.
14780 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
14782 * keyboard.c (read_key_sequence_remapped): New var.
14783 (read_key_sequence): Compute remapping in the right buffer.
14784 (command_loop_1): Use read_key_sequence's remapping directly.
14786 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
14788 * dired.c (file_name_completion): Don't expand file name.
14789 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
14790 before checking file name handler.
14792 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
14793 they've been requested explicitly (bug#9591).
14795 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
14797 * keymap.c (Fsingle_key_description): Use make_specified_string
14798 instead of build_string to build string from push_key_description.
14801 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14803 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
14804 This fixes a Y2038 bug on 64-bit hosts.
14805 * buffer.c (reset_buffer):
14806 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
14807 (Fclear_buffer_auto_save_failure):
14808 Use 0, not -1, to represent an unset failure time, since time_t
14809 might not be signed.
14811 Remove dependency on glibc malloc internals.
14812 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14813 Move back here from lisp.h, but with their new implementations.
14814 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14815 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
14816 * charset.c (charset_table_init): New static var.
14817 (syms_of_charset): Use it instead of xmalloc. This removes a
14818 dependency on glibc malloc internals. See Eli Zaretskii's comment in
14819 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
14820 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14821 Move back to alloc.c.
14822 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14823 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
14825 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
14827 * nsterm.m (windowDidResize): Call x_set_window_size only when
14828 ns_in_resize is true. Otherwise set pixelwidth/height and
14829 call change_frame_size (Bug#9628).
14831 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
14833 Port --enable-checking=all to Fedora 14 x86-64.
14834 * charset.c (syms_of_charset): Also account for glibc malloc's
14835 internal overhead when calculating the initial malloc maximum.
14837 Port --enable-checking=all to Fedora 14 x86.
14838 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14840 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
14841 (overrun_check_realloc, overrun_check_free):
14842 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
14843 That way, xmalloc returns a properly-aligned pointer even if
14844 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
14845 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
14846 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
14847 into account when calculating the initial malloc maximum.
14848 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
14849 Move here from alloc.c, so that charset.c can use it too.
14850 Properly align; the old code wasn't right for common 32-bit hosts
14851 when configured with --enable-checking=all.
14852 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
14853 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
14855 2011-09-29 Eli Zaretskii <eliz@gnu.org>
14857 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
14860 2011-09-28 Eli Zaretskii <eliz@gnu.org>
14862 * xdisp.c (compute_display_string_end): If there's no display
14863 string at CHARPOS, return -1.
14865 * bidi.c (bidi_fetch_char): When compute_display_string_end
14866 returns a negative value, treat the character as a normal
14867 character not covered by a display string. (Bug#9624)
14869 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
14871 * lread.c (Fread_from_string): Fix typo in docstring.
14873 2011-09-27 Eli Zaretskii <eliz@gnu.org>
14875 * xdisp.c (handle_invisible_prop): If invisible text ends on a
14876 newline, reseat the iterator instead of bidi-iterating there one
14877 character at a time. (Bug#9610)
14878 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
14879 TO_CHARPOS if the bidi iterator is at base embedding level.
14881 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
14883 * lread.c (readevalloop): Use correct code for NBSP.
14884 (read1): Likewise. (Bug#9608)
14886 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
14888 * dbusbind.c (Fdbus_register_signal): When service is not
14889 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
14891 2011-09-25 Glenn Morris <rgm@gnu.org>
14893 * buffer.c (truncate-lines): Doc fix.
14895 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
14897 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
14898 (Fset_window_next_buffers): Doc fix.
14900 2011-09-24 Glenn Morris <rgm@gnu.org>
14902 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
14904 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
14906 Fix minor problems found by static checking.
14907 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
14908 * indent.c (Fvertical_motion): Fix == vs = typo.
14910 2011-09-24 Eli Zaretskii <eliz@gnu.org>
14912 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
14913 Default value is now t. Doc fix.
14915 * indent.c (Fvertical_motion): Compute and apply the overshoot
14916 logic when moving up, not only when moving down. Fix the
14917 confusing name and values of the it_overshoot_expected variable;
14918 logic changes accordingly. (Bug#9254) (Bug#9549)
14920 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
14921 CHARPOS is covered by a display string which includes newlines.
14922 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
14923 is covered by a display string with embedded newlines.
14925 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
14927 * dbusbind.c (Fdbus_register_signal): Add match rule to
14928 Vdbus_registered_objects_table. (Bug#9581)
14929 (Fdbus_register_method, Vdbus_registered_objects_table):
14932 2011-09-24 Jim Meyering <meyering@redhat.com>
14934 do not ignore write error for any output size
14935 The previous change was incomplete.
14936 While it makes emacs --batch detect the vast majority of stdout
14937 write failures, errors were still ignored whenever the output size is
14938 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
14939 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
14940 && echo FAIL: ignored write error
14941 FAIL: ignored write error
14942 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
14943 && echo FAIL: ignored write error
14944 FAIL: ignored write error
14945 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
14947 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
14949 * emacs.c (Fkill_emacs): In noninteractive mode exit
14950 non-successfully if a write error occurred on stdout. (Bug#9574)
14952 2011-09-21 Eli Zaretskii <eliz@gnu.org>
14954 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
14957 * dispextern.h (struct it): Update the comment documenting what
14960 2011-09-20 Eli Zaretskii <eliz@gnu.org>
14962 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
14963 a display string, extend search for cursor position to end of row.
14964 (find_row_edges): If the row ends in a newline from a display
14965 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
14966 Handle the case of a display string with multiple newlines.
14967 (Fcurrent_bidi_paragraph_direction): Fix search for previous
14968 non-empty line. Fixes confusing cursor motion with arrow keys at
14969 the beginning of a line that starts with whitespace.
14971 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
14973 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
14976 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
14978 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
14979 boolean (Bug#9154).
14981 2011-09-18 Eli Zaretskii <eliz@gnu.org>
14983 * xdisp.c (display_line): Record maximum and minimum buffer
14984 positions even if no glyphs were produced (e.g., by a zero-width
14985 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
14986 buffer positions that will be removed from the glyph row because
14988 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
14989 column is beyond frame width: don't subtract 1 "pixel" when
14990 computing width of the stretch.
14991 (reseat_at_next_visible_line_start): Undo the change made on
14992 2011-09-17 that saved paragraph information and restored it after
14993 the call to `reseat'. (Bug#9545)
14995 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
14997 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
14998 and turn window cursor on if cleared (Bug#9415).
15000 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15002 * search.c (boyer_moore): Take unibyte characters from pattern
15003 literally. (Bug#9458)
15005 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15007 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15009 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15011 Fix minor problem found by static checking.
15012 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15013 initialized, to pacify gcc -Wuninitialized.
15015 * fileio.c: Report proper errno when syscall falls.
15016 (Finsert_file_contents): Save and restore errno,
15017 so that report_file_error outputs the correct diagnostic.
15018 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15020 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15022 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15024 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15026 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15027 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)

15031 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15032 about the current paragraph and restore it after the call to reseat.
15034 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15035 (bidi_find_paragraph_start): Search back for paragraph beginning
15036 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15037 (bidi_move_to_visually_next): Only trigger paragraph-related
15038 computations when the last character is a newline or at EOB, not
15039 just any NEUTRAL_B. (Bug#9470)
15041 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15042 truncated lines if point is covered by a display string. (Bug#9524)
15044 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15046 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15047 (cons_to_x_long): New function.
15048 (lisp_data_to_selection_data): Use it. Correct the test for
15049 short-versus-long data; it was negated. Break out of vector
15050 loop, for efficiency, when a long datum is discovered.
15052 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15054 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15056 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15058 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see

15074 * term.c (encode_terminal_code):
15075 * composite.c (composition_update_it, get_composition_id):
15076 * xdisp.c (get_next_display_element)
15077 (fill_composite_glyph_string): Add comments about special meaning
15078 of TAB characters in a composition.
15080 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15082 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15083 This occurs when processing a multibyte format.
15084 Problem reported by Wolfgang Jenker.
15086 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15088 * xdisp.c (try_cursor_movement): Only check for exact match if
15089 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15091 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15093 Remove unused external symbols.
15094 * dispextern.h (calc_pixel_width_or_height): Remove decl.

15101 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15103 * xselect.c: Use signed conversions more consistently (Bug#9498).
15104 (selection_data_to_lisp_data): Assume incoming selection data are
15105 signed integers, not unsigned. This is to be consistent with
15106 outgoing selection data, which was modified to use signed integers
15107 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15108 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15109 expects long, not unsigned long.

15121 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15123 * indent.c (compute_motion): Process display vector front to back
15124 rather than the other way around. (Bug#2496)
15126 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15128 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.

15141 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15142 value for non-existent files.
15144 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15146 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15147 set its "size" to -1. This will set the modtime_size field of
15148 the corresponding buffer to -1, which is what
15149 verify-visited-file-modtime expects for files that do not exist.
15152 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15154 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15156 * lisp.h: ... from here. push_key_description is no longer
15157 defined in keyboard.c, so its declaration should not be in
15158 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15159 logically belongs with push_key_description.
15161 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15163 * buffer.h: Include <sys/types.h> instead of <time.h>.
15164 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15165 Problem reported by Herbert J. Skuhra.
15167 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15169 * xml.c (parse_region): Make the parsing work for
15170 non-comment-starting XML files again (bug#9144).
15172 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15174 * image.c (gif_load): Fix calculation of bottom and right corner.
15177 2011-09-10 Eli Zaretskii <eliz@gnu.org>
15179 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
15180 redisplay in small windows.
15182 2011-09-09 Eli Zaretskii <eliz@gnu.org>
15184 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
15186 2011-09-08 Martin Rudalics <rudalics@gmx.at>
15188 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
15189 Operate on live windows only.
15191 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
15193 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
15195 2011-09-07 Eli Zaretskii <eliz@gnu.org>
15197 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
15198 only under bidi iteration.
15200 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
15202 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
15204 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15206 isnan: Fix porting problem to Solaris 10 with bundled gcc.
15207 Without this fix, the command to link temacs failed due to an
15208 undefined symbol __builtin_isnan. This is because
15209 /usr/include/iso/math_c99.h #defines isnan(x) to
15210 __builtin_isnan(x), but the bundled gcc, which identifies itself
15211 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
15213 * floatfns.c (isnan): #undef, and then #define to a clone of
15215 (Fisnan): Always define, since it's always available now.
15216 (syms_of_floatfns): Always define isnan at the Lisp level.
15218 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15220 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
15222 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
15224 * fileio.c: Fix bugs with large file offsets (Bug#9428).
15225 The previous code assumed that file offsets (off_t values) fit in
15226 EMACS_INT variables, which is not true on typical 32-bit hosts.
15227 The code messed up by falsely reporting buffer overflow in cases
15228 such as (insert-file-contents "big" nil 1 2) into an empty buffer
15229 when "big" contains more than 2**29 bytes, even though this
15230 inserts just one byte and does not overflow the buffer.
15231 (Finsert_file_contents): Store file offsets as off_t
15232 values, not as EMACS_INT values. Check for overflow when
15233 converting between EMACS_INT and off_t. When checking for
15234 buffer overflow or for overlap, take the offsets into account.
15235 Don't use EMACS_INT for small values where int suffices.
15236 When checking for overlap, fix a typo: ZV was used where
15237 ZV_BYTE was intended.
15238 (Fwrite_region): Don't assume off_t fits into 'long'.
15239 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
15241 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
15243 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
15245 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15247 sprintf-related integer and memory overflow issues (Bug#9412).
15249 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
15250 (esprintf, exprintf, evxprintf): New functions.
15251 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
15252 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
15253 (modify_event_symbol): Do not assume that the length of
15254 name_alist_or_stem is safe to alloca and fits in int.
15255 (Fexecute_extended_command): Likewise for function name and binding.
15256 (Frecursion_depth): Wrap around reliably on integer overflow.
15257 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
15258 since some callers pass EMACS_INT values.
15259 (Fsingle_key_description): Don't crash if symbol name contains more
15260 than MAX_ALLOCA bytes.
15261 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
15262 (get_minibuffer): Arg is now EMACS_INT, not int.
15263 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
15264 (esprintf, exprintf, evxprintf): New decls.
15265 * window.h (command_loop_level, minibuf_level): Reflect API changes.
15267 * dbusbind.c (signature_cat): New function.
15268 (xd_signature, Fdbus_register_signal):
15269 Do not overrun buffer; instead, report string overflow.
15271 * dispnew.c (add_window_display_history): Don't overrun buffer.
15272 Truncate instead; this is OK since it's just a log.
15274 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
15275 even if the time zone offset is outlandishly large.
15276 Don't mishandle offset == INT_MIN.
15278 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
15279 when creating daemon; the previous buffer-overflow check was incorrect.
15281 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
15282 which has the guts of the old verror function.
15284 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
15285 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
15287 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
15288 (font_unparse_xlfd): Don't blindly alloca long strings.
15289 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
15290 fits in int, when using sprintf. Use single snprintf to count
15291 length of string rather than counting it via multiple sprintfs;
15292 that's simpler and more reliable.
15293 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
15294 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
15295 sprintf, in case result does not fit in int.
15297 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
15298 (fontset_from_font): Print it.
15300 * frame.c (tty_frame_count): Now printmax_t, not int.
15301 (make_terminal_frame, set_term_frame_name): Print it.
15302 (x_report_frame_params): In X, window IDs are unsigned long,
15303 not signed long, so print them as unsigned.
15304 (validate_x_resource_name): Check for implausibly long names,
15305 and don't assume name length fits in 'int'.
15306 (x_get_resource_string): Don't blindly alloca invocation name;
15307 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
15310 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
15311 (xg_check_special_colors, xg_set_geometry):
15312 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
15314 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
15315 Use esprintf, not sprintf, in case result does not fit in int.
15317 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15318 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
15319 it as a large positive number.
15320 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
15321 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
15323 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
15324 in case result does not fit in int.
15326 * print.c (float_to_string): Detect width overflow more reliably.
15327 (print_object): Make sprintf buffer a bit bigger, to avoid potential
15328 buffer overrun. Don't assume list length fits in 'int'. Treat
15329 print length of 0 as 0, not as infinity; to be consistent with other
15330 uses of print length in this function. Don't overflow print length
15331 index. Don't assume hash table size fits in 'long', or that
15332 vectorlike size fits in 'unsigned long'.
15334 * process.c (make_process): Use printmax_t, not int, to format
15335 process-name gensyms.
15337 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
15339 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
15340 to avoid potential buffer overrun.
15342 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
15343 if X resource line is longer than 512 bytes.
15345 * xfns.c (x_window): Make sprintf buffer a bit bigger
15346 to avoid potential buffer overrun.
15348 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
15350 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
15352 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
15354 Integer overflow fixes for scrolling, etc.
15355 Without these, Emacs silently mishandles large integers sometimes.
15356 For example, "C-u 4294967297 M-x recenter" was treated as if
15357 it were "C-u 1 M-x recenter" on a typical 64-bit host.
15359 * xdisp.c (try_window_id): Check Emacs fixnum range before
15360 converting to 'int'.
15362 * window.c (window_scroll_line_based, Frecenter):
15363 Check that an Emacs fixnum is in range before assigning it to 'int'.
15364 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
15365 values converted from Emacs fixnums.
15366 (Frecenter): Don't wrap around a line count if it is out of 'int'
15367 range; instead, treat it as an extreme value.
15368 (Fset_window_configuration, compare_window_configurations):
15369 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
15371 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
15372 that can exceed INT_MAX. Check that EMACS_INT value is in range
15373 before assigning it to the (possibly-narrower) index.
15374 (match_limit): Don't assume that a fixnum can fit in 'int'.
15376 * print.c (print_object): Use ptrdiff_t, not int, for index that can
15379 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
15380 (Fvertical_motion): Don't wrap around LINES values that don't fit
15381 in 'int'. Instead, treat them as extreme values. This is good
15382 enough for windows, which can't have more than INT_MAX lines anyway.
15384 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
15386 * Require libxml/parser.h to avoid compilation warning.
15388 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
15390 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
15391 since this reportedly can destroy thread storage.
15393 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
15395 * syntax.c (find_defun_start): Update all cache variables if
15396 exiting early (Bug#9401).
15398 2011-08-30 Eli Zaretskii <eliz@gnu.org>
15400 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
15402 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
15403 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
15404 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
15406 * term.c (tty_append_glyph): New function.
15407 (produce_stretch_glyph): Static function and its prototype deleted.
15409 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
15412 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
15414 * image.c (parse_image_spec): Check for nonnegative, not for positive,
15415 when checking :margin (Bug#9390).
15416 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
15417 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
15418 so that the name doesn't mislead. All uses changed.
15420 2011-08-28 Johan Bockgård <bojohan@gnu.org>
15422 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
15425 2011-08-27 Eli Zaretskii <eliz@gnu.org>
15427 * xdisp.c (move_it_to): Don't bail out early when reaching
15428 position beyond to_charpos, if we are scanning backwards.
15429 (move_it_vertically_backward): When DY == 0, make sure we get to
15430 the first character in the line after the newline.
15432 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
15434 * ccl.c: Improve and simplify overflow checking (Bug#9196).
15435 (ccl_driver): Do not generate an out-of-range pointer.
15436 (Fccl_execute_on_string): Remove unnecessary check for
15437 integer overflow, noted by Stefan Monnier in
15438 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
15439 Remove a FIXME that didn't need fixing.
15440 Simplify the newly-introduced buffer reallocation code.
15442 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
15444 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
15446 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
15448 Integer and memory overflow issues (Bug#9196).
15450 * doc.c (get_doc_string): Rework so that
15451 get_doc_string_buffer_size is the actual buffer size, rather than
15452 being 1 less than the actual buffer size; this makes xpalloc more
15455 * image.c (x_allocate_bitmap_record, cache_image):
15456 * xselect.c (Fx_register_dnd_atom):
15457 Simplify previous changes by using xpalloc.
15459 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
15460 since either will do and ptrdiff_t is convenient with xpalloc.
15462 * charset.c (charset_table_size)
15463 (struct charset_sort_data.priority): Now ptrdiff_t.
15464 (charset_compare): Don't overflow if priorities differ greatly.
15465 (Fsort_charsets): Don't assume list length fits in int.
15466 Check for size-calculation overflow when allocating sort data.
15467 (syms_of_charset): Allocate an initial charset table that is
15468 just under 64 KiB, to avoid problems with glibc malloc and mmap.
15470 * cmds.c (internal_self_insert): Check for size-calculation overflow.
15472 * composite.h (struct composition.glyph_len): Now int, not unsigned.
15473 The actual value is always <= INT_MAX, and leaving it unsigned made
15474 overflow checking harder.
15476 * dispextern.h (struct glyph_matrix.rows_allocated)
15477 (struct face_cache.size): Now ptrdiff_t, for convenience in use
15478 with xpalloc. The values are still always <= INT_MAX.
15480 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
15482 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
15483 (SAFE_NALLOCA): New macro.
15485 * region-cache.c (struct boundary.pos, find_cache_boundary)
15486 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
15487 (set_cache_region, invalidate_region_cache)
15488 (revalidate_region_cache, know_region_cache, region_cache_forward)
15489 (region_cache_backward, pp_cache):
15490 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
15491 so that ptrdiff_t * can be passed to xpalloc.
15492 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
15493 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
15494 (pp_cache): Don't assume cache_len fits in int.
15495 * region-cache.h: Adjust extern decls to match.
15497 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
15498 EMACS_INT, since either will do, for xpalloc.
15500 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
15501 (xnmalloc, xnrealloc, xpalloc): New functions.
15503 * bidi.c (bidi_shelve_header_size): New constant.
15504 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
15505 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
15507 * bidi.c (bidi_cache_shrink):
15508 * buffer.c (overlays_at, overlays_in, record_overlay_string)
15510 Don't update size of array until after memory allocation succeeds,
15511 because xmalloc/xrealloc may not return.
15512 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
15513 now that we have proper integer overflow checking.
15514 (record_overlay_string, overlay_strings): Catch overflows when
15515 calculating size of overlay_str_buf.
15517 * callproc.c (Fcall_process): Check for size overflow when
15518 calculating size of args2.
15519 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
15520 Normally we prefer signed values, but sticking with ptrdiff_t would
15521 require adding more-complicated checks.
15523 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
15524 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
15525 Redo buffer-overflow calculations to avoid integer overflow.
15526 Add a FIXME comment where memory seems to be over-allocated.
15528 * character.c (Fstring): Check for size-calculation overflow.
15530 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
15531 unnecessary integer overflow. Check for size overflow.
15532 (encode_coding_object): Don't update size until xmalloc succeeds.
15534 * composite.c (get_composition_id): Check for overflow in glyph
15535 length calculations.
15537 Integer and memory overflow fixes for display code.
15538 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
15539 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
15540 (scrolling_window): Check for overflow in size calculations.
15541 (line_draw_cost, realloc_glyph_pool, add_row_entry):
15542 Don't assume glyph table len fits in int.
15543 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
15544 (row_table_size): Now ptrdiff_t, not int.
15545 (scrolling_window): Avoid overflow in size calculations.
15546 Don't update size until allocation succeeds.
15547 * fns.c (concat): Check for overflow in size calculations.
15548 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
15549 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
15550 (NEXT_ALMOST_PRIME_LIMIT): New constant.
15552 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
15553 (get_doc_string): Check for size calculation overflow.
15554 Don't update size until allocation succeeds.
15555 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
15556 EMACS_INT, where ptrdiff_t will do.
15557 (Fsubstitute_command_keys): Check for string overflow.
15559 * editfns.c (set_time_zone_rule): Don't assume environment length
15561 (message_length): Now ptrdiff_t, not int.
15562 (Fmessage_box): Don't update size until allocation succeeds.
15563 Don't assume message length fits in int.
15564 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
15566 * emacs.c (main): Do not reallocate argv, since there is a null at
15567 the end that can be overwritten, and this way there's no need to
15568 worry about size-calculation overflow.
15569 (sort_args): Check for size-calculation overflow.
15571 * eval.c (init_eval_once, grow_specpdl): Don't update size until
15573 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
15575 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
15576 (x_set_scroll_bar_width, x_figure_window_size):
15577 Check for integer overflow.
15578 (x_set_alpha): Do not assume XINT fits in int.
15580 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
15581 This is for the members text_lines, text_cols, total_lines, total_cols,
15582 where the system imposes an 'int' limit.
15584 * fringe.c (Fdefine_fringe_bitmap):
15585 Don't update size until alloc works.
15587 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
15588 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
15590 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
15591 Check for size-calculation overflow.
15592 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
15593 do, as we prefer signed integers.

15649 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
15650 for command line length. Do not attempt to address one before the
15651 beginning of an array, as that's not portable.
15653 * term.c (max_frame_lines): Remove; unused.

15683 memory exhaustion (the usual treatment), rather than aborting.
15685 * xfns.c (x_encode_text, x_set_name_internal)
15686 (Fx_change_window_property): Use ptrdiff_t, not int, to count
15687 sizes, since they can exceed INT_MAX in size. Check for size
15688 calculation overflow.

15691 (xg_select): Check for size calculation overflow.
15692 Don't update size until alloc done.
15694 * xrdb.c (get_environ_db): Don't assume path length fits in int,
15695 as sprintf is limited to int lengths.
15697 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
15698 (X_LONG_MIN): New macros.
15699 Use them to make the following changes clearer.
15700 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
15701 This change doesn't affect the value now, but it may help remind
15702 future maintainers not to raise the value too much later.
15703 (SELECTION_QUANTUM): Remove, replacing with ...
15704 (selection_quantum): ... new function, which avoids overflow.
15706 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
15707 assumption that selection length fits in 'int'.

15724 Don't store size until memory allocation succeeds.
15725 (x_get_window_property): Plug memory leak on memory exhaustion.
15726 Don't double-block input; malloc is safe here. Don't assume 2**34
15727 - 4 fits in unsigned long. Add an xassert to check
15728 XGetWindowProperty overflow. Be more careful about overflow
15729 calculations, and distinguish size from memory overflow better.
15730 (receive_incremental_selection): When tracing, don't assume
15731 unsigned int is less than INT_MAX.
15732 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

15736 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
15737 result parameters unless successful. Rely on cons_to_unsigned
15738 to report problems with elements; the old code wasn't right anyway.
15739 (x_check_property_data): Check for int overflow; we cannot use
15740 a wider type due to X limits.

15773 * lisp.h (hash_lookup, hash_put):
15774 * minibuf.c (Ftest_completion):
15775 Use ptrdiff_t for hash table indexes, not int (which is too
15776 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
15777 32-bit --with-wide-int hosts).
15779 * charset.c (Fdefine_charset_internal): Check for integer overflow.
15780 Add a FIXME comment about memory leaks.

15788 with outlandish widths.
15789 * character.h (sanitize_tab_width): Rename from sanitize_width,
15790 now that we have two such functions. All uses changed.

15808 * xterm.c: Don't go over XClientMessageEvent limit.
15809 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
15810 (x_send_scroll_bar_event): Likewise. Check that the size does not
15811 exceed limits imposed by XClientMessageEvent, as well as the usual
15812 ptrdiff_t and size_t limits.
15814 * keyboard.c: Overflow, signedness and related fixes.
15815 (make_lispy_movement): Use same integer type in forward decl
15816 that is used in the definition.
15817 (read_key_sequence, keyremap_step):
15818 Change bufsize argument back to int, undoing my 2011-03-30 change.
15819 We prefer signed types, and int is wide enough here.
15820 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
15821 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
15822 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
15823 length, not size_t. Use ptrdiff_t for index, not int.
15824 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
15825 possibility of integer overflow.
15827 Overflow, signedness and related fixes for images.

15849 (lookup_image): Remove unnecessary tests.
15850 (xbm_image_p): Locals are now of int, not EMACS_INT,
15851 since parse_image_check makes sure they fit into int.
15852 (png_load, gif_load, svg_load_image):
15853 Prefer int to unsigned where either will do.
15854 (tiff_handler): New function, combining the cores of the
15855 old tiff_error_handler and tiff_warning_handler.
15856 This function is rewritten to use vsnprintf and thereby avoid
15857 stack buffer overflows. It uses only the features of vsnprintf
15858 that are common to both POSIX and native Microsoft.
15859 (tiff_error_handler, tiff_warning_handler): Use it.
15860 (tiff_load, gif_load, imagemagick_load_image):
15861 Don't assume :index value fits in 'int'.
15862 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
15863 (imagemagick_load_image): Check that crop parameters fit into
15864 the integer types that MagickCropImage accepts. Don't assume
15865 Vimagemagick_render_type has a nonnegative value. Don't assume
15866 size_t fits in 'long'.
15867 (gs_load): Use printmax_t to print the widest integers possible.
15868 Check for integer overflow when computing image height and width.

15881 (handle_single_display_spec): If the display spec is of the form
15882 `(space ...)', and specifies display in the text area, return 2
15884 (try_cursor_movement): Check for the need to scroll more
15885 accurately, and prefer exact match for point under bidi.
15886 Don't advance `row' beyond the last row of the window.

15904 buffers, return left-to-right.
15905 (set_cursor_from_row): Consider candidate row a win if its glyph
15906 represents a newline and point is on that newline. Fixes cursor
15907 positioning on the newline at EOL of R2L text within L2R
15908 paragraph, and vice versa.
15909 (try_cursor_movement): Check continued rows, in addition to
15910 continuation rows. Fixes unwarranted scroll when point enters a
15911 continued line of R2L text within an L2R paragraph, or vice versa.
15912 (cursor_row_p): Consider the case of point being equal to
15913 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
15914 from the end of a short line to the beginning of a continued line
15915 of R2L text within L2R paragraph.
15916 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

15939 * xdisp.c (redisplay_window): When computing centering_position,
15940 account for the height of the header line. (Bug#8874)
15942 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
15943 instead of CHAR_TO_BYTE. Fixes a crash when a completion
15944 candidate is selected by the mouse, and that candidate has a
15945 composed character under the mouse.
15947 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
15948 coordinates reported by pos-visible-in-window-p for a composed
15949 character in column zero.
15951 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

15955 2011-08-22 Eli Zaretskii <eliz@gnu.org>
15957 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
15958 consider it a hit if to_charpos is anywhere in the range of the
15959 composed buffer positions.
15961 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
15963 * image.c (gif_load): Don't assume that each subimage has the same
15964 dimensions as the base image. Handle disposal method that is
15965 "undefined" by the gif spec (Bug#9335).
15967 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
15969 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

15974 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
15975 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
15976 from an Org mode buffer to a Speedbar frame.
15978 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
15979 a composition, take its buffer position from IT->cmp_it.charpos.
15980 Fixes cursor positioning at the beginning of a line that begins
15981 with a composed character.
15983 2011-08-18 Eli Zaretskii <eliz@gnu.org>
15985 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
15986 character bidirectional type, use STRONG_L instead. Fixes crashes
15987 in a buffer produced by `describe-categories'.
15989 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
15990 members before the level stack, so they would be saved and
15991 restored when copying iterator state. Fixes incorrect reordering
15992 around TABs covered by display properties.
15994 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
15996 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

16020 Fix memory allocation problems in Cygwin build (Bug#9273).
16022 * unexcw.c ( __malloc_initialized): Declare external variable.
16023 (fixup_executable): Force the dumped emacs to reinitialize malloc.
16025 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
16027 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

16030 in the static heap.
16031 [CYGWIN] (special_realloc): New function.
16032 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
16033 requests to realloc storage in the static heap.
16035 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
16037 * bidi.c (bidi_initialize): Remove unused local.
16039 2011-08-15 Eli Zaretskii <eliz@gnu.org>
16042 * biditype.h: Remove file.
16043 * makefile.w32-in ($(BLD)/bidi.$(O)):
16044 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
16046 * dispextern.h: Fix a typo in the comment to bidi_type_t.
16048 * chartab.c: Improve commentary for the uniprop_table API.
16050 * bidi.c (bidi_paragraph_init): Support zero value of
16051 bidi_ignore_explicit_marks_for_paragraph_level.
16052 (bidi_initialize): Use uniprop_table instead of including
16053 biditype.h and bidimirror.h.
16055 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
16056 coordinates of the iterator when restoring from ppos_it.
16059 2011-08-14 Kenichi Handa <handa@m17n.org>
16061 * process.c (create_process): Call setup_process_coding_systems
16062 after the pid of the process is set to -1 (Bug#8162).
16064 2011-08-14 Eli Zaretskii <eliz@gnu.org>
16066 * xdisp.c (move_it_in_display_line_to): Don't invoke
16067 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16068 ppos_it. Fixes vertical cursor motion when line beginning is
16069 covered by an image. (Bug#9296)
16071 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16073 * nsterm.h (ns_run_ascript): Declare.
16074 (NSAPP_DATA2_RUNASSCRIPT): Define.
16076 * nsfns.m (as_script, as_result, as_status): New static variables.
16077 (ns_run_ascript): New function.
16078 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16079 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16080 the event loop. Get status from as_status (Bug#7276).
16082 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16083 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16084 the event loop (Bug#7276).
16086 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16088 * gnutls.c (QCgnutls_bootprop_priority)
16089 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16090 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16091 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16092 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16093 (QCgnutls_bootprop_verify_hostname_error)
16094 (QCgnutls_bootprop_callbacks_verify): Rename from
16095 Qgnutls_bootprop_..., all uses changed.
16097 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16100 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16102 * xfaces.c (Qframe_set_background_mode): Now static.
16103 * dispextern.h (Qframe_set_background_mode): Remove decl.
16105 * process.c (Fnetwork_interface_info): Declare local only if needed.
16107 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16109 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16110 (Fnetwork_interface_list): Allocate in increments of bytes instead
16111 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16112 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16114 (struct ifflag_def): notrailers is smart on OSX.
16115 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16116 Get hardware address with getifaddrs if available.
16118 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16120 * xdisp.c (iterate_out_of_display_property): xassert that
16121 IT->position is set to within IT->object's boundaries. Break from
16122 the loop as soon as EOB is reached; avoids infloops in redisplay
16123 when IT->position is set up wrongly due to some bug.
16124 Set IT->current to match the bidi iterator unconditionally.
16125 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16126 entry. Force push_it to save on the stack the current
16127 buffer/string position, to be restored by pop_it. Fix flags in
16128 the iterator structure wrt the object coming from a display
16129 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16130 properties. (Bug#9284)
16132 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16134 * fontset.c (fontset_get_font_group): Add proper type checks.
16137 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16139 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16140 and LC_VERSION_MIN_MACOSX.
16141 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16142 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16144 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16146 * xdisp.c (forward_to_next_line_start): Allow to use the
16147 no-display-properties-and-no-overlays under bidi display.
16148 Set disp_pos in the bidi iterator to avoid searches for display
16149 properties and overlays.
16151 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16153 * editfns.c (Fset_time_zone_rule): Document relationship with the
16156 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16157 the font entity extracted from the cache (Bug#8109).
16159 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16161 * composite.c (autocmp_chars): Don't reset point. That is done by
16162 restore_point_unwind (Bug#5984).
16164 2011-08-07 Juri Linkov <juri@jurta.org>
16166 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16167 to show the arg `TIME' instead of `TIMEVAL'.
16169 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16171 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16172 display property strides EOL and includes a newline, as in
16173 longlines-mode. (Bug#9254)
16174 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16175 word-wrap under bidirectional display. (Bug#9224)
16177 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16178 is non-zero, even if the data buffer is NULL. Fixes a crash in
16179 vertical-motion with longlines-mode. (Bug#9254)
16181 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16183 * bidi.c <bidi_cache_total_alloc>: Now static.
16184 (bidi_initialize): Initialize bidi_cache_total_alloc.
16186 * xdisp.c (display_line): Release buffer allocated for shelved bidi
16189 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
16190 amount allocated this far in `bidi_cache_total_alloc'.
16191 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
16192 non-zero, only free the data buffer without restoring the cache
16193 contents. All callers changed.
16195 * dispextern.h (bidi_unshelve_cache): Update prototype.
16197 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
16198 (move_it_in_display_line, move_it_to)
16199 (move_it_vertically_backward, move_it_by_lines): Replace the call
16200 to xfree to an equivalent call to bidi_unshelve_cache.
16201 (move_it_in_display_line_to): Fix logic of returning
16202 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
16204 2011-08-05 Eli Zaretskii <eliz@gnu.org>
16206 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
16207 came from a string character with a `cursor' property. (Bug#9229)
16209 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16211 * Makefile.in (LIB_PTHREAD): New variable.
16212 (LIBES): Add LIB_PTHREAD (Bug#9216).
16214 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
16215 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
16217 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
16219 * regex.c (re_iswctype): Remove some redundant boolean conversions.
16221 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
16223 * xterm.c (x_find_topmost_parent): New function.
16224 (x_set_frame_alpha): Find topmost parent window with
16225 x_find_topmost_parent and set the property there also (bug#9181).
16226 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
16228 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
16230 * callproc.c (Fcall_process): Avoid vfork clobbering
16231 the local vars buffer, coding_systems, current_dir.
16233 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
16235 * keymap.c (Fmake_composed_keymap): Move to subr.el.
16237 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
16239 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
16240 so that it is not optimized away.
16242 * xdisp.c (compute_display_string_pos): Remove unused local.
16244 2011-08-02 Eli Zaretskii <eliz@gnu.org>
16246 Fix slow cursor motion and scrolling in large buffers with
16247 selective display, like Org Mode buffers. (Bug#9218)
16249 * dispextern.h (struct bidi_it): New member disp_prop_p.
16251 * xdisp.c: Remove one-slot cache of display string positions.
16252 (compute_display_string_pos): Accept an additional argument
16253 DISP_PROP_P; callers changed. Scan at most 5K characters forward
16254 for a display string or property. If found, set DISP_PROP_P
16257 * bidi.c (bidi_fetch_char): Accept an additional argument
16258 DISP_PROP_P, and pass it to compute_display_string_pos.
16259 Only handle text covered by a display string if DISP_PROP_P is returned
16260 non-zero. All callers of bidi_fetch_char changed.
16262 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
16264 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
16266 2010-12-03 Don March <don@ohspite.net>
16268 * keymap.c (Fdefine_key): Fix non-prefix key error message when
16269 last character M-[char] is translated to ESC [char] (bug#7541).
16271 2011-08-02 Kenichi Handa <handa@m17n.org>
16273 * lisp.h (uniprop_table): Extern it.
16275 * chartab.c (uniprop_table): Make it non-static.
16277 2011-08-01 Eli Zaretskii <eliz@gnu.org>
16279 * xdisp.c (forward_to_next_line_start): Accept additional argument
16280 BIDI_IT_PREV, and store into it the state of the bidi iterator had
16282 (reseat_at_next_visible_line_start): Use the bidi iterator state
16283 returned by forward_to_next_line_start to restore the state of
16284 it->bidi_it after backing up to previous newline. (Bug#9212)
16286 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
16288 * regex.c (re_comp): Protoize.
16289 (re_exec): Fix return type.
16290 (regexec): Fix type of `ret'. (Bug#9203)
16292 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16294 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
16295 This is needed if max-image-size is a floating-point number.
16297 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16299 * print.c (print_object): Print empty symbol as ##.
16301 * lread.c (read1): Read ## as empty symbol.
16303 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16305 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
16306 setting frame foreground color (Bug#9175).
16307 (x_set_background_color): Likewise.
16309 * nsmenu.m (-setText): Size tooltip dimensions precisely to
16310 contents (Bug#9176).
16311 (EmacsTooltip -init): Remove bezels and add shadows to
16314 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
16315 or scroll bar (Bug#8470).
16317 * nsfont.m (nsfont_open): Remove assignment to voffset and
16318 unnecessary vars hshink, expand, hd, full_height, min_height.
16319 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
16321 * nsterm.h (nsfont_info): Remove voffset field.
16323 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
16325 Implement strike-through and overline on NextStep (Bug#8863).
16327 * nsfont.m (nsfont_open): Use underline position provided by font,
16328 instead of hard-coded value of 2.
16329 (nsfont_draw): Call ns_draw_text_decoration instead.
16331 * nsterm.h: Add declaration for ns_draw_text_decoration.
16333 * nsterm.m (ns_draw_text_decoration): New function for drawing
16334 underline, overline, and strike-through.
16335 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
16336 ns_draw_text_decoration. Change treatment of cursor drawing to
16337 accommodate underlining, etc.
16339 2011-07-28 Eli Zaretskii <eliz@gnu.org>
16341 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
16344 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16346 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
16347 Without this fix, if a signal arrives just after memory fills up,
16348 'malloc' might be invoked reentrantly.
16350 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
16351 In other words, assume that every image size is allowed, on non-X
16352 hosts. This assumption is probably wrong, but it lets Emacs compile.
16354 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
16356 * regex.c (re_iswctype): Convert return values to boolean.
16358 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
16360 * xdisp.c (compute_display_string_pos): Don't use cached display
16361 string position if the buffer had its restriction changed.
16364 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16366 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
16368 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
16370 Integer signedness and overflow and related fixes. (Bug#9079)
16372 * bidi.c: Integer size and overflow fixes.
16373 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
16374 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
16375 (bidi_cache_find_level_change, bidi_cache_ensure_space)
16376 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
16377 (bidi_find_other_level_edge):
16378 Use ptrdiff_t instead of EMACS_INT where either will do.
16379 This works better on 32-bit hosts configured --with-wide-int.
16380 (bidi_cache_ensure_space): Check for size-calculation overflow.
16381 Use % rather than repeated addition, for better worst-case speed.
16382 Don't set bidi_cache_size until after xrealloc returns, because it
16384 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
16385 (bidi_cache_ensure_space): Also check that the bidi cache size
16386 does not exceed that of the largest Lisp string or buffer. See Eli
16387 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
16389 * alloc.c (__malloc_size_t): Remove.
16390 All uses replaced by size_t. See Andreas Schwab's note
16391 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
16393 * image.c: Improve checking for integer overflow.
16394 (check_image_size): Assume that f is nonnull, since
16395 it is always nonnull in practice. This is one less thing to
16396 worry about when checking for integer overflow later.
16397 (x_check_image_size): New function, which checks for integer
16398 overflow issues inside X.
16399 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
16400 This removes the need for a memory_full check.
16401 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
16402 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
16403 (xbm_read_bitmap_data): Change locals back to 'int', since
16404 their values must fit in 'int'.
16405 (xpm_load_image, png_load, tiff_load):
16406 Invoke x_create_x_image_and_pixmap earlier,
16407 to avoid much needless work if the image is too large.
16408 (tiff_load): Treat overly large images as if
16409 x_create_x_image_and_pixmap failed, not as malloc failures.
16410 (gs_load): Use x_check_image_size.
16412 * gtkutil.c: Omit integer casts.
16413 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
16414 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
16416 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
16418 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
16419 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
16420 would wrongly return t on a 64-bit host.
16422 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
16423 The plain *_OVERFLOW macros run afoul of GCC bug 49705
16424 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
16425 and therefore cause GCC to emit a bogus diagnostic in some cases.
16427 * image.c: Integer signedness and overflow and related fixes.
16428 This is not an exhaustive set of fixes, but it's time to
16429 record what I've got.
16430 (lookup_pixel_color, check_image_size): Remove redundant decls.
16431 (check_image_size): Don't assume that arbitrary EMACS_INT values
16432 fit in 'int', or that arbitrary 'double' values fit in 'int'.
16433 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
16434 (tiff_load, imagemagick_load_image):
16435 Check for overflow in size calculations.
16436 (x_create_x_image_and_pixmap): Remove unnecessary test for
16437 xmalloc returning NULL; that can't happen.
16438 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
16439 (xpm_color_bucket): Use better integer hashing function.
16440 (xpm_cache_color): Don't possibly over-allocate memory.
16441 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
16442 (gif_memory_source):
16443 Use ptrdiff_t, not int or size_t, to record sizes.
16444 (png_load): Don't assume values greater than 2**31 fit in 'int'.
16445 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
16446 either works, as we prefer signed integers.
16447 (tiff_read_from_memory, tiff_write_from_memory):
16448 Return tsize_t, not size_t, since that's what the TIFF API wants.
16449 (tiff_read_from_memory): Don't fail simply because the read would
16450 go past EOF; instead, return a short read.
16451 (tiff_load): Omit no-longer-needed casts.
16452 (Fimagemagick_types): Don't assume size fits into 'int'.
16454 Improve hashing quality when configured --with-wide-int.
16455 * fns.c (hash_string): New function, taken from sxhash_string.
16456 Do not discard information about ASCII character case; this
16457 discarding is no longer needed.
16458 (sxhash-string): Use it. Change sig to match it. Caller changed.
16459 * lisp.h: Declare it.
16460 * lread.c (hash_string): Remove, since we now use fns.c's version.
16461 The fns.c version returns a wider integer if --with-wide-int is
16462 specified, so this should help the quality of the hashing a bit.
16464 * emacs.c: Integer overflow minor fix.
16465 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
16466 Define only if GNU_LINUX.
16467 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
16469 * dispnew.c: Integer signedness and overflow fixes.
16470 Remove unnecessary forward decls, that were a maintenance hassle.
16471 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
16473 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
16474 (scrolling_window): Use ptrdiff_t, not int, for byte count.
16475 (prepare_desired_row, line_draw_cost):
16476 Use int, not unsigned, where either works.
16477 (save_current_matrix, restore_current_matrix):
16478 Use ptrdiff_t, not size_t, where either works.
16479 (init_display): Check for overflow more accurately, and without
16480 relying on undefined behavior.
16482 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
16483 Remove, replacing with the new symbols in lisp.h. All uses changed.
16484 * fileio.c (make_temp_name):
16485 * filelock.c (lock_file_1, lock_file):
16486 * xdisp.c (message_dolog):
16487 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
16488 Use pMd etc. instead.
16489 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
16490 replacing the pWIDE etc. symbols removed from editfns.c.
16492 * keyboard.h (num_input_events): Now uintmax_t.
16493 This is (very slightly) less likely to mess up due to wraparound.
16496 * buffer.c: Integer signedness fixes.
16497 (alloc_buffer_text, enlarge_buffer_text):
16498 Use ptrdiff_t rather than size_t when either will do, as we prefer
16501 * alloc.c: Integer signedness and overflow fixes.
16502 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
16503 (__malloc_size_t): Default to size_t, not to int.
16504 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
16505 (Fgarbage_collect, mark_object_loop_halt, mark_object):
16506 Prefer ptrdiff_t to size_t when either would do, as we prefer
16508 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
16509 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
16510 Now const. Initialize with values that are in range even if char
16512 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
16513 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
16514 These functions do the right thing with sizes > 2**32.
16515 (check_depth): Now ptrdiff_t, not int.
16516 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
16517 Adjust to new way of storing sizes. Check for size overflow bugs
16519 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
16520 slightly wrong anyway, as it missed one instance of
16521 XMALLOC_OVERRUN_CHECK_OVERHEAD.
16522 (refill_memory_reserve): Omit needless cast to size_t.
16523 (mark_object_loop_halt): Mark as externally visible.
16525 * xselect.c: Integer signedness and overflow fixes.
16526 (Fx_register_dnd_atom, x_handle_dnd_message):
16527 Use ptrdiff_t, not size_t, since we prefer signed.
16528 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
16529 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
16530 x_dnd_atoms_size and x_dnd_atoms_length.
16532 * doprnt.c: Prefer signed to unsigned when either works.
16534 * doprnt.c (doprnt):
16536 * xdisp.c (vmessage):
16537 Use ptrdiff_t, not size_t, when using or implementing doprnt,
16538 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
16539 prefer signed arithmetic to avoid comparison confusion.
16540 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
16541 but is a bit tricky.
16543 Assume freestanding C89 headers, string.h, stdlib.h.
16544 * data.c, doprnt.c, floatfns.c, print.c:
16545 Include float.h unconditionally.
16546 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
16547 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
16548 * regex.c: Likewise for stddef.h, string.h.
16549 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
16550 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
16551 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
16552 (STDC_HEADERS): Remove obsolete defines.
16553 * sysdep.c: Include limits.h unconditionally.
16555 Assume support for memcmp, memcpy, memmove, memset.
16556 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
16557 * regex.c (memcmp, memcpy):
16558 Remove; we assume C89 now.
16560 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
16561 (__malloc_safe_bcopy): Remove; no longer needed.
16563 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
16564 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
16565 well either way, and we prefer signed to unsigned.
16567 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
16569 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
16570 closes the connection while we're reading (bug#9182).
16572 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
16574 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
16575 are specified (Bug#9168).
16577 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
16579 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
16580 Found by GCC static checking and --with-wide-int on a 32-bit host.
16582 2011-07-25 Eli Zaretskii <eliz@gnu.org>
16584 * xdisp.c (compute_display_string_pos): Fix logic of caching
16585 previous display string position. Initialize cached_prev_pos to
16586 -1. Fixes slow-down at the beginning of a buffer.
16588 2011-07-24 Eli Zaretskii <eliz@gnu.org>
16590 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
16591 for attrs[LFACE_FONTSET_INDEX].
16593 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
16595 * xml.c (parse_region): Remove unused local
16596 that was recently introduced.
16598 2011-07-23 Eli Zaretskii <eliz@gnu.org>
16600 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
16601 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
16603 * xdisp.c (move_it_in_display_line_to): Record the best matching
16604 position for TO_CHARPOS while scanning the line, and restore it on
16605 exit if none of the characters scanned was an exact match.
16606 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
16607 when exact match is impossible due to invisible text, and the
16608 lines are truncated.
16610 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
16612 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
16615 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16617 Fix a significant slow-down of cursor motion with C-n, C-p,
16618 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
16619 auto-repeat under bidi redisplay in fontified buffers.
16620 * xdisp.c (compute_stop_pos_backwards): New function.
16621 (next_element_from_buffer): Call compute_stop_pos_backwards to
16622 find a suitable prev_stop when we find ourselves before
16624 (reseat): Don't look for prev_stop, as that could mean a very long
16626 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
16627 <cached_disp_overlay_modiff>: Cache for last found display string
16629 (compute_display_string_pos): Return the cached position if asked
16630 about the same buffer in the same area of character positions, and
16631 the buffer wasn't changed since the time the display string
16632 position was cached.
16634 2011-07-22 Eli Zaretskii <eliz@gnu.org>
16636 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
16637 is an integer, which is important for empty lines. (Bug#9149)
16639 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
16641 * frame.c (Fmodify_frame_parameters): In tty case, update the
16642 default face if necessary (Bug#4238).
16644 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
16646 * editfns.c (Fstring_to_char): No need to explain what a character
16647 is in the docstring (Bug#6576).
16649 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16651 * xml.c (parse_region): Make sure we always return a tree.
16653 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
16655 * xml.c (parse_region): If a document contains only comments,
16658 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
16660 * xml.c (make_dom): Return comments, too.
16662 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
16665 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
16666 and the surrounding thread.
16667 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
16668 rather than fgets, and retry after EINTR. Otherwise, 'emacs
16669 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
16671 * s/openbsd.h (BROKEN_SIGIO): Define.
16672 * unexelf.c (unexec) [__OpenBSD__]:
16673 Don't update the .mdebug section of the Alpha COFF symbol table.
16675 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16677 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
16680 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
16682 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
16683 This fixes some race conditions on the permissions of any newly
16686 * alloc.c (valid_pointer_p): Use pipe, not open.
16687 This fixes some permissions issues when debugging.
16689 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
16690 If fchown fails to set both uid and gid, try to set just gid,
16691 as that is sometimes allowed. Adjust the file's mode to eliminate
16692 setuid or setgid bits that are inappropriate if fchown fails.
16694 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
16696 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
16697 to compare Lisp_Objects.
16698 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
16699 global_gnutls_log_level, don't mistake it for a Lisp_Object.
16700 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
16702 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
16704 * lread.c (read_integer): Unread even EOF character.
16705 (read1): Likewise. Properly record start position of symbol.
16707 * lread.c (read1): Read `#:' as empty uninterned symbol if no
16708 symbol character follows.
16710 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
16712 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
16713 This works around a problem with the previous change to Fcopy_file.
16714 Recent glibc declares fchown with __attribute__((warn_unused_result)),
16715 and without this change, GCC might complain about discarding
16716 fchown's return value.
16718 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
16720 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
16722 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
16724 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
16726 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
16728 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
16729 it's used from the C level.
16731 * process.c: Use the same condition for POLL_FOR_INPUT in both
16732 keyboard.c and process.c (bug#1858).
16734 2011-07-09 Lawrence Mitchell <wence@gmx.li>
16736 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
16737 (Fgnutls_boot): Use it.
16739 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
16741 * doc.c (Fsubstitute_command_keys): Revert last change.
16743 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
16745 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
16746 quotes the next character, and doesn't affect other longer
16747 sequences (bug#8935).
16749 * lread.c (syms_of_lread): Clarify that is isn't only
16750 `eval-buffer' and `eval-defun' that's affected by
16751 `lexical-binding' (bug#8460).
16753 2011-07-15 Eli Zaretskii <eliz@gnu.org>
16755 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
16756 bidi redisplay when a line includes both an image and is truncated.
16758 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
16760 Fix minor problems found by static checking.
16761 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
16762 (elsz): Now a signed constant, not a size_t var. We prefer signed
16763 types to unsigned, to avoid integer comparison confusion. Without
16764 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
16765 "cannot optimize loop, the loop counter may overflow", a symptom
16767 * indent.c (Fvertical_motion): Mark locals as initialized.
16768 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
16770 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
16772 * search.c (Fre_search_backward): Mention `case-fold-search' in
16773 all the re_search_* functions (bug#8138).
16775 * keyboard.c (Fopen_dribble_file): Document when the file is

16780 * bidi.c (bidi_dump_cached_states): Fix format of displaying
16783 Support bidi reordering of display and overlay strings.

16785 (compute_display_string_end): Accept additional argument STRING.
16786 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
16787 (reseat_to_string): Initialize bidi_it->string.s and
16788 bidi_it->string.schars.
16789 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
16790 NULL (avoids a crash in bidi_paragraph_init).
16791 Initialize itb.string.lstring.
16792 (init_iterator): Call bidi_init_it only of a valid
16793 buffer position was specified. Initialize paragraph_embedding to
16795 (reseat_to_string): Initialize the bidi iterator.
16796 (display_string): If we need to ignore text properties of
16797 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
16798 original value of -1 will not work with bidi.)
16799 (compute_display_string_pos): First arg is now struct
16800 `text_pos *'; all callers changed. Support display properties on
16802 (compute_display_string_end): Support display properties on Lisp
16804 (init_iterator, reseat_1, reseat_to_string): Initialize the
16805 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
16806 when iterating on a string not from display properties).
16807 (compute_display_string_pos, compute_display_string_end):
16808 Fix calculation of the object to scan. Fixes an error when using
16810 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
16811 base_level_stop; instead, set base_level_stop to BEGV.
16812 Fixes crashes in vertical-motion.
16813 (next_element_from_buffer): Improve commentary for when
16814 the iterator is before prev_stop.
16815 (init_iterator): Initialize bidi_p from the default value of
16816 bidi-display-reordering, not from buffer-local value. Use the
16817 buffer-local value only if initializing for buffer iteration.
16818 (handle_invisible_prop): Support invisible properties on strings
16819 that are being bidi-reordered.
16820 (set_iterator_to_next): Support bidi reordering of C strings and
16822 (next_element_from_string): Support bidi reordering of Lisp
16824 (handle_stop_backwards): Support Lisp strings as well.
16825 (display_string): Support display of R2L glyph rows.
16826 Use IT_STRING_CHARPOS when displaying from a Lisp string.
16827 (init_iterator): Don't initialize it->bidi_p for strings
16829 (reseat_to_string): Initialize it->bidi_p for strings here.
16830 (next_element_from_string, next_element_from_c_string)
16831 (next_element_from_buffer): Add xassert's for correspondence
16832 between IT's object being iterated and it->bidi_it.string
16834 (face_before_or_after_it_pos): Support bidi iteration.
16835 (next_element_from_c_string): Handle the case of the first string
16836 character that is not the first one in the visual order.
16837 (get_visually_first_element): New function, refactored from common
16838 parts of next_element_from_buffer, next_element_from_string, and
16839 next_element_from_c_string.
16840 (tool_bar_lines_needed, redisplay_tool_bar)
16841 (display_menu_bar): Force left-to-right direction. Add a FIXME
16842 comment for making that be controlled by a user option.
16843 (push_it, pop_it): Save and restore the state of the
16844 bidi iterator. Save and restore the bidi_p flag.
16845 (pop_it): Iterate out of display property for string iteration as
16847 (iterate_out_of_display_property): Support iteration over strings.
16848 (handle_single_display_spec): Set up it->bidi_it for iteration
16849 over a display string, and call bidi_init_it.
16850 (handle_single_display_spec, next_overlay_string)
16851 (get_overlay_strings_1, push_display_prop): Set up the bidi
16852 iterator for displaying display or overlay strings.
16853 (forward_to_next_line_start): Don't use the shortcut if
16855 (back_to_previous_visible_line_start): If handle_display_prop
16856 pushed the iterator stack, restore the internal state of the bidi
16857 iterator by calling bidi_pop_it same number of times.
16858 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
16859 and we are bidi-iterating, don't decrement the iterator position;
16860 instead, set the first_elt flag in the bidi iterator, to produce
16862 (reseat_1): Remove redundant setting of string_from_display_prop_p.
16863 (push_display_prop): xassert that we are iterating a buffer.
16864 (push_it, pop_it): Save and restore paragraph_embedding member.
16865 (handle_single_display_spec, next_overlay_string)
16866 (get_overlay_strings_1, reseat_1, reseat_to_string)
16867 (push_display_prop): Set up the `unibyte' member of bidi_it.string
16868 correctly. Don't assume unibyte strings are not bidi-reordered.
16869 (compute_display_string_pos)
16870 (compute_display_string_end): Fix handling the case of C string.
16871 (push_it, pop_it): Save and restore from_disp_prop_p.
16872 (handle_single_display_spec, push_display_prop): Set the
16873 from_disp_prop_p flag.
16874 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
16875 (pop_it): Call iterate_out_of_display_property only if we are
16876 popping after iteration over a string that came from a display
16877 property. Fix a typo in popping stretch info. Add an assertion
16878 for verifying that the iterator position is in sync with the bidi
16880 (handle_single_display_spec, get_overlay_strings_1)
16881 (push_display_prop): Fix initialization of paragraph direction for
16882 string when that of the parent object is not yet determined.
16883 (reseat_1): Call bidi_init_it to resync the bidi
16884 iterator with IT's position. (Bug#7616)
16885 (find_row_edges): If ROW->start.pos gives position
16886 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
16887 (handle_stop, back_to_previous_visible_line_start, reseat_1):
16888 Reset the from_disp_prop_p flag.
16889 (SAVE_IT, RESTORE_IT): New macros.
16890 (pos_visible_p, face_before_or_after_it_pos)
16891 (back_to_previous_visible_line_start)
16892 (move_it_in_display_line_to, move_it_in_display_line)
16893 (move_it_to, move_it_vertically_backward, move_it_by_lines)
16894 (try_scrolling, redisplay_window, display_line): Use them when
16895 saving a temporary copy of the iterator and restoring it back.
16896 (back_to_previous_visible_line_start, reseat_1)
16897 (init_iterator): Empty the bidi cache "stack".
16898 (move_it_in_display_line_to): If iterator ended up at
16899 EOL, but we never saw any buffer positions smaller than
16900 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
16901 motion in bidi-reordered lines.
16902 (move_it_in_display_line_to): Record prev_method and prev_pos
16903 immediately before the call to set_iterator_to_next. Fixes cursor
16904 motion in bidi-reordered lines with stretch glyphs and strings
16905 displayed in margins. (Bug#8133) (Bug#8867)
16906 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
16908 (pos_visible_p): Support positions in bidi-reordered lines.
16909 Save and restore bidi cache.
16911 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
16912 (bidi_paragraph_info): Delete unused struct.
16913 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
16914 (bidi_cache_start): New variable.
16915 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

17334 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
17335 subseconds part to the entropy, as that's a bit more random.
17336 Prefer signed to unsigned, since the signedness doesn't matter and
17337 in general we prefer signed. When given a limit, use a
17338 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
17339 latter isn't right if USE_2_TAGS_FOR_INTS.
17340 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
17341 not 0..VALMASK. Don't discard "excess" bits that random () returns.

17367 * fns.c (Frequire): Remove the mention of the .gz files, since
17368 that's installation-specific, but keep the mention of

17486 * eval.c (struct backtrace): Simplify and port the data structure.
17487 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
17488 signed bit field, as this assumption is not portable and it makes
17489 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
17490 "char debug_on_exit : 1" as this is not portable either; instead,
17491 use the portable "unsigned int debug_on_exit : 1". Remove unused
17492 member evalargs. Remove obsolete comments about cc bombing out.
17494 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

17564 (emacs_fixed_get_preferred_height): Use min_width/height from
17565 frames size_hint to set minimum and natural (Bug#8919).
17566 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
17567 and use min_width/height from frames size_hint to set
17568 min_width/height (Bug#8919).

17661 (PRINTPREPARE, printchar, strout):
17662 Don't set size unless allocation succeeds.
17664 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
17665 for sizes. Check for string overflow more accurately.

17680 to improve quality of diagnostics for out-of-range radices.
17681 Calculate buffer size correctly for out-of-range radices.
17682 (read1): Check for integer overflow in radices, and in
17683 read-circle numbers.
17684 (read_escape): Avoid int overflow.
17685 (Fload, openp, read_buffer_size, read1)
17686 (substitute_object_recurse, read_vector, read_list, map_obarray):

17709 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
17710 The following patches are for when GLYPH_DEBUG && !XASSERT.
17711 * dispextern.h (trace_redisplay_p, dump_glyph_string):
17712 * dispnew.c (flush_stdout):
17713 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
17714 Mark as externally visible.
17715 * dispnew.c (check_window_matrix_pointers): Now static.

17726 (debug_method_add): Use va_list and vsprintf rather than relying
17727 on undefined behavior with wrong number of arguments.
17728 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
17729 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
17730 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
17731 since we're not interested in debugging glyphs with old libraries.
17732 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
17733 GCC 4.6.0's static checking.
17735 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

17769 Use ptrdiff_t, not int, for sizes.
17770 (overlays_at, overlays_in): Check for size-calculation overflow.
17772 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
17774 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
17775 (x_session_initialize): Do not assume string length fits in int.
17777 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
17778 This is unlikely, but can occur if DPI is outlandish.
17780 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
17781 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
17783 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
17784 * xrdb.c (magic_file_p, search_magic_path):
17785 Omit last arg SUFFIX; it was always 0. All callers changed.
17786 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
17788 * xfont.c (xfont_match): Avoid need for strlen.
17790 * xfns.c: Don't assume strlen fits in int.

17793 * xdisp.c (message_log_check_duplicate): Return intmax_t,
17794 not unsigned long, as we prefer signed integers. All callers changed.
17795 Detect integer overflow in repeat count.
17796 (message_dolog): Don't assume print length fits in 39 bytes.
17797 (display_mode_element): Don't assume strlen fits in int.
17799 * termcap.c: Don't assume sizes fit in int and never overflow.
17800 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
17801 (gobble_line): Check for size-calculation overflow.
17803 * minibuf.c (Fread_buffer):
17804 * lread.c (intern, intern_c_string):
17805 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
17806 Don't assume string length fits in int.
17808 * keyboard.c (parse_tool_bar_item):
17809 * gtkutil.c (style_changed_cb): Avoid need for strlen.
17811 * font.c: Don't assume string length fits in int.
17812 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
17813 Use ptrdiff_t, not int.
17814 (font_intern_prop): Don't assume string length fits in int.
17815 Don't assume integer property fits in fixnum.
17816 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
17818 * filelock.c: Fix some buffer overrun and integer overflow issues.
17819 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
17820 Reformulate so as not to need the command string.
17821 Invoke gzip -cd rather than gunzip, as it's more portable.
17822 (lock_info_type, lock_file_1, lock_file):
17823 Don't assume pid_t and time_t fit in unsigned long.
17824 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
17825 (current_lock_owner): Prefer signed type for sizes.
17826 Use memcpy, not strncpy, where memcpy is what is really wanted.
17827 Don't assume (via atoi) that time_t and pid_t fit in int.
17828 Check for time_t and/or pid_t out of range, e.g., via a network share.
17829 Don't alloca where an auto var works fine.
17831 * fileio.c: Fix some integer overflow issues.
17832 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
17833 Don't assume string length fits in int.
17834 (directory_file_name): Don't assume string length fits in long.
17835 (make_temp_name): Don't assume pid fits in int, or that its print
17836 length is less than 20.
17838 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
17840 * coding.c (make_subsidiaries): Don't assume string length fits in int.
17842 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
17844 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
17845 We prefer signed integers, even for size calculations.
17847 * emacs.c: Don't assume string length fits in 'int'.
17848 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
17849 (main): Don't invoke strlen when not needed.
17851 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
17852 (XD_DEBUG_MESSAGE): Don't waste a byte.
17854 * callproc.c (getenv_internal_1, getenv_internal)
17855 (Fgetenv_internal):
17856 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
17858 * lread.c (invalid_syntax): Omit length argument.
17859 All uses changed. This doesn't fix a bug, but it simplifies the
17860 code away from its former Hollerith-constant appearance, and it's
17861 one less 'int' to worry about when looking at integer-overflow issues.
17862 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
17864 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
17865 This didn't break anything, but it didn't help either.
17866 It's confusing to put a bogus integer in a place where the actual
17867 value does not matter.
17868 (LIST_END_P): Remove unused macro and its bogus comment.
17869 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
17871 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
17872 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
17874 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
17875 We prefer signed types, and the value cannot exceed the EMACS_INT
17876 range anyway (because otherwise the length would not be representable).
17877 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
17878 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
17879 This avoids a GCC warning when WIDE_EMACS_INT.
17881 * indent.c (sane_tab_width): New function.
17882 (current_column, scan_for_column, Findent_to, position_indentation)
17883 (compute_motion): Use it. This is just for clarity.
17884 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
17886 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
17888 * lisp.h (lint_assume): New macro.
17889 * composite.c (composition_gstring_put_cache):
17890 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
17892 * editfns.c, insdel.c:
17893 Omit unnecessary forward decls, to simplify future changes.
17895 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
17897 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
17899 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
17900 Use much-faster test for byte-length change.
17901 Don't assume string byte-length fits in 'int'.
17902 Check that character arg fits in 'int'.
17903 (mapcar1): Declare byte as byte, for clarity.
17905 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
17907 * fns.c (concat): Catch string overflow earlier.
17908 Do not rely on integer wraparound.
17910 * dispextern.h (struct it.overlay_strings_charpos)
17911 (struct it.selective): Now EMACS_INT, not int.
17912 * xdisp.c (forward_to_next_line_start)
17913 (back_to_previous_visible_line_start)
17914 (reseat_at_next_visible_line_start, next_element_from_buffer):
17915 Don't arbitrarily truncate the value of 'selective' to int.
17917 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
17919 * composite.c: Don't truncate sizes to 'int'.
17920 (composition_gstring_p, composition_reseat_it)
17921 (composition_adjust_point): Use EMACS_INT, not int.
17922 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
17923 not EMACS_UINT, for indexes.
17925 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
17927 * buffer.c: Include <verify.h>.
17928 (struct sortvec.priority, struct sortstr.priority):
17929 Now EMACS_INT, not int.
17930 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
17931 (struct sortstr.size, record_overlay_string)
17932 (struct sortstrlist.size, struct sortlist.used):
17933 Don't truncate size to int.
17934 (record_overlay_string): Check for size-calculation overflow.
17935 (init_buffer_once): Check at compile-time, not run-time.
17937 2011-06-22 Jim Meyering <meyering@redhat.com>
17939 Don't leak an XBM-image-sized buffer
17940 * image.c (xbm_load): Free the image buffer after using it.
17942 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
17945 * composite.c (find_automatic_composition): Omit needless 'return 0;'
17946 that Sun C diagnosed.
17947 * fns.c (secure_hash): Fix pointer signedness issue.
17948 * intervals.c (static_offset_intervals): New function.
17949 (offset_intervals): Use it.
17951 2011-06-21 Leo Liu <sdl.web@gmail.com>
17954 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
17957 * fns.c (secure_hash): Rename from crypto_hash_function and change
17958 the first arg to accept symbols.
17959 (Fsecure_hash): New primitive.
17960 (syms_of_fns): New symbols.
17962 2011-06-20 Deniz Dogan <deniz@dogan.se>
17964 * process.c (Fset_process_buffer): Clarify return value in
17967 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
17969 * dispnew.c (add_window_display_history): Use BVAR.
17971 * xdisp.c (debug_method_add): Use BVAR.
17972 (check_window_end, dump_glyph_matrix, dump_glyph)
17973 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
17975 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
17978 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
17979 check till after the cache is created in init_frame_faces.
17981 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
17983 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
17985 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
17987 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
17988 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
17989 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
17991 Improve buffer-overflow checking (Bug#8873).
17992 * fileio.c (Finsert_file_contents):
17993 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
17994 Remove the old (too-loose) buffer overflow checks.
17995 They weren't needed, since make_gap checks for buffer overflow.
17996 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
17997 The old code merely checked for Emacs fixnum overflow, and relied
17998 on undefined (wraparound) behavior. The new code avoids undefined
17999 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18001 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18002 Tune. Don't use wider integers than needed. Don't use alloca.
18003 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18005 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18007 * insdel.c, lisp.h (buffer_overflow): New function.
18008 (insert_from_buffer_1, replace_range, replace_range_2):
18009 * insdel.c (make_gap_larger):
18010 * editfns.c (Finsert_char):
18011 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18013 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18015 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18017 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18019 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18020 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18022 * fileio.c: Don't assume EMACS_INT fits in off_t.
18023 (emacs_lseek): New static function.
18024 (Finsert_file_contents, Fwrite_region): Use it.
18025 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18027 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18029 * fns.c: Don't overflow int when computing a list length.
18030 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18031 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18032 truncation on 64-bit hosts. Check for QUIT every
18033 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18034 faster and is responsive enough.
18035 (Flength): Report an error instead of overflowing an integer.
18036 (Fsafe_length): Return a float if the value is not representable
18037 as a fixnum. This shouldn't happen except in contrived situations.
18038 (Fnthcdr, Fsort): Don't assume list length fits in int.
18039 (Fcopy_sequence): Don't assume vector length fits in int.
18041 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18042 (header_size, word_size): New constants.
18043 (allocate_vectorlike): Don't check size overflow here.
18044 (allocate_vector): Check it here instead, since this is the only
18045 caller of allocate_vectorlike that could cause overflow.
18046 Check that the new vector's length is representable as a fixnum.
18048 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18049 The previous code was bogus. For example, next_almost_prime (32)
18050 returned 39, which is undesirable as it is a multiple of 3; and
18051 next_almost_prime (24) returned 25, which is a multiple of 5 so
18052 why was the code bothering to check for multiples of 7?
18054 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18056 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18058 Variadic C functions now count arguments with ptrdiff_t.
18059 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18060 Back then I didn't know that the Emacs coding style prefers signed int.
18061 Also, in the meantime I found a few more instances where arguments
18062 were being counted with int, which may truncate counts on 64-bit
18063 machines, or EMACS_INT, which may be unnecessarily wide.
18064 * lisp.h (struct Lisp_Subr.function.aMANY)
18065 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18066 Arg counts are now ptrdiff_t, not size_t.
18067 All variadic functions and their callers changed accordingly.
18068 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18069 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18070 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18071 * callint.c (Fcall_interactively): Check arg count for overflow,
18072 to avoid potential buffer overrun. Use signed char, not 'int',
18073 for 'varies' array, so that we needn't bother to check its size
18074 calculation for overflow.
18075 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18076 * eval.c (apply_lambda):
18077 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18078 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18079 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18081 * callint.c (Fcall_interactively): Don't use index var as event count.
18083 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18084 * mem-limits.h (SIZE): Remove; no longer used.
18086 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18088 Remove unnecessary casts.
18089 * xterm.c (x_term_init):
18090 * xfns.c (x_set_border_pixel):
18091 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18092 These aren't needed now that we assume ANSI C.
18094 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18095 It's more likely to cause problems (due to unsigned overflow)
18098 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18100 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18102 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18104 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18106 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18108 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18110 GLYPH_CODE_FACE returns EMACS_INT, not int.
18111 * dispextern.h (merge_faces):
18112 * xfaces.c (merge_faces):
18113 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18114 Don't assume EMACS_INT fits in int.
18116 * character.h (CHAR_VALID_P): Remove unused parameter.
18117 * fontset.c, lisp.h, xdisp.c: All uses changed.
18119 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18121 * fns.c (concat): Minor tuning based on overflow analysis.
18122 This doesn't fix any bugs. Use int to hold character, instead
18123 of constantly refetching from Emacs object. Use XFASTINT, not
18124 XINT, for value known to be a character. Don't bother comparing
18125 a single byte to 0400, as it's always less.
18127 * floatfns.c (Fexpt):
18128 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18130 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18133 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18135 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18136 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18137 incorrectly succeed when S was a string, because 4294967386 was
18138 truncated before it was used.
18140 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18141 Otherwise, an out-of-range integer could cause undefined behavior
18144 * composite.c: Use int, not EMACS_INT, for characters.
18145 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18146 EMACS_INT, for values that are known to be in character range.
18147 This doesn't fix any bugs but is the usual style inside Emacs and
18148 may generate better code on 32-bit machines.
18150 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18151 This is for reasons similar to the recent CHAR_STRING fix.
18152 * charset.c (Fencode_char): Check that character arg is actually
18153 a character. Pass an int to ENCODE_CHAR.
18154 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18155 wider than 'int', as a compile-time check to prevent future regressions
18158 * character.c (char_string): Remove unnecessary casts.
18160 Make sure a 64-bit char is never passed to CHAR_STRING.
18161 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18162 by silently ignoring the top 32 bits, allowing some values
18163 that were far too large to be valid characters.
18164 * character.h: Include <verify.h>.
18165 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18166 arguments are no wider than unsigned, as a compile-time check
18167 to prevent future regressions in this area.
18169 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18170 (Fsubst_char_in_region):
18172 * xdisp.c (decode_mode_spec_coding):
18173 Adjust to CHAR_STRING's new requirement.
18174 * editfns.c (Finsert_char, Fsubst_char_in_region):
18175 * fns.c (concat): Check that character args are actually
18176 characters. Without this test, these functions did the wrong
18177 thing with wildly out-of-range values on 64-bit hosts.
18179 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
18180 These casts should not be needed on 32-bit hosts, either.
18181 * keyboard.c (read_char):
18182 * lread.c (Fload): Remove casts to unsigned.
18184 * lisp.h (UNSIGNED_CMP): New macro.
18185 This fixes comparison bugs on 64-bit hosts.
18186 (ASCII_CHAR_P): Use it.
18187 * casefiddle.c (casify_object):
18188 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
18189 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
18190 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
18191 * dispextern.h (FACE_FROM_ID):
18192 * keyboard.c (read_char): Use UNSIGNED_CMP.
18194 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
18195 not to EMACS_INT, to avoid GCC warning.
18197 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
18199 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
18200 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
18201 isn't needed on 32-bit machines.
18203 * buffer.c (Fgenerate_new_buffer_name):
18204 Use EMACS_INT for count, not int.
18205 (advance_to_char_boundary): Return EMACS_INT, not int.
18207 * data.c (Qcompiled_function): Now static.
18209 * window.c (window_body_lines): Now static.
18211 * image.c (gif_load): Rename local to avoid shadowing.
18213 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
18214 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
18215 * alloc.c (make_save_value): Integer argument is now of type
18216 ptrdiff_t, not int.
18217 (mark_object): Use ptrdiff_t, not int.
18218 * lisp.h (pD): New macro.
18219 * print.c (print_object): Use it.
18221 * alloc.c: Use EMACS_INT, not int, to count objects.
18222 (total_conses, total_markers, total_symbols, total_vector_size)
18223 (total_free_conses, total_free_markers, total_free_symbols)
18224 (total_free_floats, total_floats, total_free_intervals)
18225 (total_intervals, total_strings, total_free_strings):
18226 Now EMACS_INT, not int. All uses changed.
18227 (Fgarbage_collect): Compute overall total using a double, so that
18228 integer overflow is less likely to be a problem. Check for overflow
18229 when converting back to an integer.
18230 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
18231 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
18232 These were 'int' variables that could overflow on 64-bit hosts;
18233 they were never used, so remove them instead of repairing them.
18234 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
18235 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
18236 Previously, this ceilinged at INT_MAX, but that doesn't work on

18686 (slurp_file): Switch from int to ptrdiff_t.
18688 (slurp_file): Check that file size fits in both size_t (for
18689 malloc) and ptrdiff_t (for sanity and safety).

18692 if b->modtime has its maximal value.
18694 * dired.c (Ffile_attributes): Don't assume EMACS_INT has >32 bits.

18701 Minor fixes for signed vs unsigned integers.
18702 * character.h (MAYBE_UNIFY_CHAR):
18703 * charset.c (maybe_unify_char):
18704 * keyboard.c (read_char, reorder_modifiers):
18705 XINT -> XFASTINT, since the integer must be nonnegative.

18710 since it makes no difference and we prefer signed.
18711 * keyboard.c (record_char): Use XUINT when all the neighbors do.
18712 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

18763 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
18764 Do not assume that spare memory exists; that assumption is valid
18765 only if SYSTEM_MALLOC.
18766 (LARGE_REQUEST): New macro, so that the issue of large requests
18767 is separated from the issue of spare memory.
18769 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>

18828 (bidi_paragraph_init, bidi_resolve_explicit_1)
18829 (bidi_level_of_next_char): Call bidi_fetch_char and

18836 instead of using explicit *_CHAR codes.
18837 (bidi_resolve_explicit, bidi_resolve_weak):
18838 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
18839 bidirectional text is supported only in multibyte buffers.

18846 (bidi_level_of_next_char): Don't try to lookup the cache for the
18847 next/previous character if nothing is cached there yet, or if we
18848 were just reseat()'ed to a new position.
18850 * xdisp.c (set_cursor_from_row): Set start and stop points
18851 according to the row's direction when priming the loop that looks
18852 for the glyph on which to display cursor.
18853 (single_display_spec_intangible_p): Function deleted.
18854 (display_prop_intangible_p): Reimplement to call
18855 handle_display_spec instead of single_display_spec_intangible_p.
18856 Accept 3 additional arguments needed by handle_display_spec.
18857 This fixes incorrect cursor motion across display property with complex
18858 values: lists, `(when COND...)' forms, etc.

18860 lists with the argument STRING its top-level element.
18861 (display_prop_string_p): Fix the condition for processing a
18862 property that is a list to be consistent with handle_display_spec.

18864 last portion of handle_display_prop.
18865 (compute_display_string_pos): Accept additional argument
18866 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
18867 value of a `display' property is a "replacing spec".
18868 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
18869 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
18870 the display property, but just return a value indicating whether
18871 the display property will replace the characters it covers.
18872 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
18873 frame_window_p members of struct bidi_it.
18874 (compute_display_string_pos, compute_display_string_end):

18877 jump to continue iteration.
18878 (reseat_1): Initialize bidi_it.disp_pos.
18880 * keyboard.c (adjust_point_for_property): Adjust the call to
18881 display_prop_intangible_p to its new signature.
18883 * dispextern.h (struct bidi_it): New member frame_window_p.
18884 (bidi_init_it): Update prototypes.

18895 * lisp.h: Change signatures accordingly.
18896 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
18897 All callers changed. (Bug#8762)
18899 * gnutls.c: Use Emacs's memory allocators.
18900 Without this change, the gnutls library would invoke malloc etc.
18901 directly, which causes problems on non-SYNC_INPUT hosts, and which
18902 runs afoul of improving memory_full behavior. (Bug#8761)
18903 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
18904 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
18905 xfree instead of the default malloc, realloc, free.
18906 (Fgnutls_boot): No need to check for memory allocation failure,
18907 since xmalloc does that for us.
18909 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
18910 * category.c (hash_get_category_set):

18927 * lisp.h (struct Lisp_Hash_Table):
18928 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
18929 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
18930 for hashes and hash indexes, instead of 'unsigned' and 'int'.
18931 * alloc.c (allocate_vectorlike):
18932 Check for overflow in vector size calculations.
18933 * ccl.c (ccl_driver):
18934 Check for overflow when converting EMACS_INT to int.
18935 * fns.c, image.c: Remove unnecessary static decls that would otherwise
18936 need to be updated by these changes.
18937 * fns.c (make_hash_table, maybe_resize_hash_table):
18938 Check for integer overflow with large hash tables.
18939 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
18940 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
18941 (SXHASH_REDUCE): New macro.
18942 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
18943 Use it instead of discarding useful hash info with large hash values.
18944 (sxhash_float): New function.
18945 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
18946 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
18947 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
18948 Rewrite to use FIXNUM_BITS, as this simplifies things.
18949 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
18950 Adjust signatures to match updated version of code.
18951 (consing_since_gc): Now EMACS_INT, since a single hash table can
18952 use more than INT_MAX bytes.
18954 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
18956 Make it possible to build with GCC-4.6+ -O2 -flto.
18958 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
18960 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
18962 * minibuf.c (get_minibuffer, read_minibuf_unwind):
18963 Call minibuffer-inactive-mode.
18965 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
18967 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
18968 Update dependencies.
18970 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18972 * data.c (init_data): Remove code for UTS, this system is not
18975 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18977 Don't force ./temacs to start in terminal mode.
18979 * frame.c (make_initial_frame): Initialize faces in all cases, not
18980 only when CANNOT_DUMP is defined.
18981 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
18983 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
18985 * dispnew.c (add_window_display_history): Use const for the string
18986 pointer. Remove declaration, not needed.
18988 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
18990 Use 'inline', not 'INLINE'.
18991 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
18992 * alloc.c, fontset.c (INLINE): Remove.
18993 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
18994 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
18995 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
18996 * gmalloc.c (register_heapinfo): Use inline unconditionally.
18997 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
18999 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19001 Make it possible to run ./temacs.
19003 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19004 syms_of_callproc does the same thing. Remove test for
19005 "initialized", do it in the caller.
19006 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19008 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19010 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.

19022 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19024 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19026 * eval.c (Qdebug): Now static.
19027 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19028 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19029 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19031 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19033 * image.c: Various fixes to ImageMagick code comments.
19034 (Fimagemagick_types): Doc fix.

19038 Minor fixes prompted by GCC 4.6.0 warnings.
19040 * xselect.c (converted_selections, conversion_fail_tag): Now static.

19043 (x_clipboard_manager_save_all): Move extern decl to ...
19044 * xterm.h: ... here, so that it can be checked for consistency.
19046 2011-05-29 Chong Yidong <cyd@stupidchicken.com>

19062 2011-05-28 Jim Meyering <meyering@redhat.com>
19064 Avoid a sign-extension bug in crypto_hash_function.
19065 * fns.c (to_uchar): Define.
19066 (crypto_hash_function): Use it to convert some newly-signed
19067 variables to unsigned, to avoid sign-extension bugs. For example,
19068 without this change, (md5 "truc") would evaluate to
19069 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19070 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19071 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19073 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19075 Integer overflow fixes.
19077 * dbusbind.c: Serial number integer overflow fixes.
19078 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19079 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19080 to hold a serial number that is too large for a fixnum.
19081 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19082 Check for serial numbers out of range. Decode any serial number
19083 that was so large that it became a float. (Bug#8722)
19085 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19086 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19087 Use XFASTINT rather than XUINT when numbers are nonnegative.
19088 (xd_append_arg, Fdbus_method_return_internal):
19089 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19090 arguments, check that Lisp number is nonnegative, rather than
19091 silently wrapping negative numbers around. (Bug#8722)
19092 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19095 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19097 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19099 ccl: Add integer overflow checks.
19100 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19101 (IN_INT_RANGE): New macros.
19102 (ccl_driver): Use them to check for integer overflow when
19103 decoding a CCL program. Many of the new checks are whether XINT (x)
19104 fits in int; it doesn't always, on 64-bit hosts. The new version
19105 doesn't catch all possible integer overflows, but it's an
19106 improvement. (Bug#8719)
19108 * alloc.c (make_event_array): Use XINT, not XUINT.
19109 There's no need for unsigned here.
19111 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19112 This follows up to the 2011-05-06 change that substituted uintptr_t
19113 for EMACS_INT. This case wasn't caught back then.
19115 Rework Fformat to avoid integer overflow issues.
19116 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19117 now (part of C89). Include <verify.h>.
19118 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19119 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19120 (Fformat): Avoid the prepass trying to compute sizes; it was only
19121 approximate and thus did not catch overflow reliably. Instead, walk
19122 through the format just once, formatting and computing sizes as we go,
19123 checking for integer overflow at every step, and allocating a larger
19124 buffer as needed. Keep track separately whether the format is
19125 multibyte. Keep only the most-recently calculated precision, rather
19126 than them all. Record whether each argument has been converted to
19127 string. Use EMACS_INT, not int, for byte and char and arg counts.
19128 Support field widths and precisions larger than INT_MAX. Avoid
19129 sprintf's undefined behavior with conversion specifications such as %#d
19130 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19131 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19132 formatting out-of-range floating point numbers with int
19133 formats. (Bug#8668)
19135 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19137 * data.c: Avoid integer truncation in expressions involving floats.
19138 * data.c: Include <intprops.h>.
19139 (arith_driver): When there's an integer overflow in an expression
19140 involving floating point, convert the integers to floating point
19141 so that the resulting value does not suffer from catastrophic
19142 integer truncation. For example, on a 64-bit host (* 4
19143 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19144 Do not rely on undefined behavior after integer overflow.
19146 merge count_size_as_multibyte, parse_str_to_multibyte
19147 * character.c, character.h (count_size_as_multibyte):
19148 Rename from parse_str_to_multibyte; all uses changed.
19149 Check for integer overflow.
19150 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19151 since it's now a duplicate of the other. This is more of
19152 a character than a buffer op, so better that it's in character.c.
19153 * fns.c, print.c: Adjust to above changes.
19155 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19157 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19159 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19161 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19162 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19163 (x_clipboard_manager_save): Now static.
19164 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19166 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19167 (crypto_hash_function): Now static.
19168 Fix pointer signedness problems. Avoid unnecessary initializations.
19170 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19172 * termhooks.h (Vselection_alist): Make it terminal-local.
19174 * terminal.c (create_terminal): Initialize it.
19176 * xselect.c: Support for clipboard managers.
19177 (Vselection_alist): Move to termhooks.h as terminal-local var.
19178 (LOCAL_SELECTION): New macro.
19179 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
19180 (symbol_to_x_atom): Remove gratuitous arg.
19181 (x_handle_selection_request, lisp_data_to_selection_data)
19182 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
19183 (x_own_selection, x_get_local_selection, x_convert_selection):
19184 New arg, specifying work frame. Use terminal-local Vselection_alist.
19185 (some_frame_on_display): Delete unused function.
19186 (Fx_own_selection_internal, Fx_get_selection_internal)
19187 (Fx_disown_selection_internal, Fx_selection_owner_p)
19188 (Fx_selection_exists_p): New optional frame arg.
19189 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
19190 (x_handle_selection_clear): Don't treat other terminals with the
19191 same keyboard specially. Use the terminal-local Vselection_alist.
19192 (x_clear_frame_selections): Use Frun_hook_with_args.
19194 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
19196 * xterm.h: Add support for those atoms.
19198 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
19200 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
19201 (converted_selections, conversion_fail_tag): New global variables.
19202 (x_selection_request_lisp_error): Free the above.
19203 (x_get_local_selection): Remove unnecessary code.
19204 (x_reply_selection_request): Args changed; handle arbitrary array
19205 of converted selections stored in converted_selections.
19206 Separate the XChangeProperty and SelectionNotify steps.
19207 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
19208 (x_convert_selection): New function.
19209 (x_handle_selection_event): Simplify.
19210 (x_get_foreign_selection): Don't ignore incoming requests while
19211 waiting for an answer; this will fail when we implement
19212 SAVE_TARGETS, and seems unnecessary anyway.
19213 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
19214 (Vx_sent_selection_functions): Doc fix.
19216 2011-05-26 Leo Liu <sdl.web@gmail.com>
19218 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
19220 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19222 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
19224 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
19225 for fringe update if it has periodic bitmap.
19226 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
19227 and fringe_bitmap_periodic_p.
19229 * fringe.c (get_fringe_bitmap_data): New function.
19230 (draw_fringe_bitmap_1, update_window_fringes): Use it.
19231 (update_window_fringes): Record periodicity of fringe bitmap in glyph
19232 row. Mark glyph row for fringe update if periodicity changed.
19234 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
19235 for fringe update unless it has periodic bitmap.
19237 2011-05-25 Kenichi Handa <handa@m17n.org>
19239 * xdisp.c (get_next_display_element): Set correct it->face_id for
19240 a static composition.
19242 2011-05-24 Leo Liu <sdl.web@gmail.com>
19245 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
19247 * fns.c (crypto_hash_function, Fsha1): New function.
19248 (Fmd5): Use crypto_hash_function.
19249 (syms_of_fns): Add Ssha1.
19251 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19253 * gnutls.c: Remove unused macros.
19254 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
19255 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
19256 Remove macros that are defined and never used.
19257 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
19259 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19261 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
19262 (Fx_get_selection_internal): Minor cleanup.
19263 (Fx_own_selection_internal): Rename arguments for consistency with
19266 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
19268 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
19270 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
19272 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
19274 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19276 * dispnew.c (scrolling_window): Don't exclude the case that the
19277 last enabled row in the desired matrix touches the bottom boundary.
19279 2011-05-21 Glenn Morris <rgm@gnu.org>
19281 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
19282 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
19283 and add some more files.
19285 2011-05-20 Eli Zaretskii <eliz@gnu.org>
19287 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
19288 report_file_error introduced by the change from 2011-05-07.
19290 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
19292 * systime.h (Time): Define only if emacs is defined.
19293 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
19294 where the include path doesn't have X11/X.h by default. See
19295 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
19297 2011-05-20 Kenichi Handa <handa@m17n.org>
19299 * composite.c (find_automatic_composition): Fix previous change.
19301 2011-05-20 Glenn Morris <rgm@gnu.org>
19303 * lisp.mk: New file, split from Makefile.in.
19304 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
19305 (shortlisp): Remove.
19306 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
19308 2011-05-19 Glenn Morris <rgm@gnu.org>
19310 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
19311 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
19312 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
19313 (lisp): Set the order to that of loadup.el.
19314 (shortlisp): Make it a copy of $lisp.
19315 (SOME_MACHINE_LISP): Remove.
19316 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
19317 Use just $shortlisp, not $SOME_MACHINE_LISP too.
19319 2011-05-18 Kenichi Handa <handa@m17n.org>
19321 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
19322 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
19323 (find_automatic_composition): Mostly rewrite for efficiency.
19325 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
19327 * makefile.w32-in: Update dependencies.
19329 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
19331 * menu.c: Include limits.h (fixes the MS-Windows build broken by
19332 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
19334 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
19336 Fix some integer overflow issues, such as string length overflow.
19338 * insdel.c (count_size_as_multibyte): Check for string overflow.
19340 * character.c (lisp_string_width): Check for string overflow.
19341 Use EMACS_INT, not int, for string indexes and lengths; in
19342 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
19343 the resulting string length overflows an EMACS_INT; instead,
19344 report a string overflow if no precision given. When checking for
19345 precision exhaustion, use a check that cannot possibly have
19346 integer overflow. (Bug#8675)
19347 * character.h (lisp_string_width): Adjust to new signature.
19349 * alloc.c (string_overflow): New function.
19350 (Fmake_string): Use it. This doesn't change behavior, but saves
19351 a few bytes and will simplify future changes.
19352 * character.c (string_escape_byte8): Likewise.
19353 * lisp.h (string_overflow): New decl.
19355 Fixups, following up to the user-interface timestamp change.
19356 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
19357 for UI timestamps, instead of unsigned long.
19358 * msdos.c (mouse_get_pos): Likewise.
19359 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
19360 * w32gui.h (Time): Define by including "systime.h" rather than by
19361 declaring it ourselves. (Bug#8664)
19363 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
19364 * image.c (clear_image_cache): Likewise.
19366 * term.c (term_mouse_position): Don't assume time_t wraparound.
19368 Be more systematic about user-interface timestamps.
19369 Before, the code sometimes used 'Time', sometimes 'unsigned long',
19370 and sometimes 'EMACS_UINT', to represent these timestamps.
19371 This change causes it to use 'Time' uniformly, as that's what X uses.
19372 This makes the code easier to follow, and makes it easier to catch
19373 integer overflow bugs such as Bug#8664.
19374 * frame.c (Fmouse_position, Fmouse_pixel_position):
19375 Use Time, not unsigned long, for user-interface timestamps.
19376 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
19377 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
19378 * keyboard.h (last_event_timestamp): Likewise.
19379 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
19380 * menu.h (xmenu_show): Likewise.
19381 * term.c (term_mouse_position): Likewise.
19382 * termhooks.h (struct input_event.timestamp): Likewise.
19383 (struct terminal.mouse_position_hook): Likewise.
19384 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
19385 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
19386 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
19387 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
19388 what it was before.
19389 * menu.h, termhooks.h: Include "systime.h", for Time.
19391 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
19392 Don't assume that the difference between two unsigned long values
19393 can fit into an integer. At this point, we know button_down_time
19394 <= event->timestamp, so the difference must be nonnegative, so
19395 there's no need to cast the result if double-click-time is
19396 nonnegative, as it should be; check that it's nonnegative, just in
19397 case. This bug is triggered when events are more than 2**31 ms
19398 apart (about 25 days). (Bug#8664)
19400 * xselect.c (last_event_timestamp): Remove duplicate decl.
19401 (x_own_selection): Remove needless cast to unsigned long.
19403 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
19404 that always fit in int. Use a sentinel instead of a counter, to
19405 avoid a temp and to allay GCC's concerns about possible int overflow.
19406 * frame.h (struct frame): Use int for menu_bar_items_used
19407 instead of EMACS_INT, since it always fits in int.
19409 * menu.c (grow_menu_items): Check for int overflow.
19411 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
19413 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
19414 Before, the code was not consistent. These values cannot exceed
19415 2**31 - 1 so there's no need to make them unsigned.
19416 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
19417 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
19418 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
19420 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
19422 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
19423 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
19424 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
19425 presumably because the widths might not match.
19427 * window.c (size_window): Avoid needless test at loop start.
19429 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
19431 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
19433 2011-05-12 Drew Adams <drew.adams@oracle.com>
19435 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
19437 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19439 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
19440 `width' to `bar_area_x' and `bar_area_width', respectively.
19441 (x_scroll_run): Take account of fringe background extension.
19443 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
19444 Rename local vars `left' and `width' to `bar_area_x' and
19445 `bar_area_width', respectively.
19446 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
19447 background extension.
19449 2011-05-10 Jim Meyering <meyering@redhat.com>
19451 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
19453 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
19455 * image.c (Finit_image_library): Return t for built-in image types,
19456 like pbm and xbm. (Bug#8640)
19458 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
19460 * w32menu.c (set_frame_menubar): Fix submenu allocation.
19462 2011-05-07 Eli Zaretskii <eliz@gnu.org>
19464 * w32console.c (Fset_screen_color): Doc fix.
19465 (Fget_screen_color): New function.
19466 (syms_of_ntterm): Defsubr it.
19468 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
19469 unlink the temporary file if Fcall_process didn't create it in the
19471 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
19472 child process will be redirected to a file specified with `:file'.
19473 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
19474 cue to call_process_cleanup not to close that handle.
19476 2011-05-07 Ben Key <bkey76@gmail.com>
19478 * makefile.w32-in: The bootstrap-temacs rule now makes use of
19479 one of two shell specific rules, either bootstrap-temacs-CMD or
19480 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
19481 to the previous implementation of the bootstrap-temacs rule.
19482 The bootstrap-temacs-CMD rule is similar to the previous
19483 implementation of the bootstrap-temacs rule except that it
19484 makes use of the ESC_CFLAGS variable instead of the CFLAGS
19487 These changes, along with some changes to nt/configure.bat,
19488 nt/gmake.defs, and nt/nmake.defs, are required to extend my
19489 earlier fix to add support for --cflags and --ldflags options
19490 that include quotes so that it works whether make uses cmd or
19493 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
19495 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
19496 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
19498 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
19499 a string. Handle both cases.
19500 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
19501 (Fdbus_register_method): Use Qinvalid_function.
19503 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19505 * makefile.w32-in: Update dependencies.
19506 (LISP_H): Add inttypes.h and stdin.h.
19507 (PROCESS_H): Add unistd.h.
19509 2011-05-06 Eli Zaretskii <eliz@gnu.org>
19511 * lread.c: Include limits.h (fixes the MS-Windows build broken by
19512 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
19514 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
19516 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
19518 * term.c (vfatal): Remove stray call to va_end.
19519 It's not needed and the C Standard doesn't allow it here anyway.
19521 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
19522 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
19524 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
19527 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
19529 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
19531 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
19533 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
19535 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
19537 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
19538 * charset.c (Fdefine_charset_internal): Don't initialize
19539 charset.code_space[15]. The value was garbage, on hosts with
19540 32-bit int (Bug#8600).
19542 * lread.c (read_integer): Be more consistent with string-to-number.
19543 Use string_to_number to do the actual conversion; this avoids
19544 rounding errors and fixes some other screwups. Without this fix,
19545 for example, #x1fffffffffffffff was misread as -2305843009213693952.
19546 (digit_to_number): Move earlier, for benefit of read_integer.
19547 Return -1 if the digit is out of range for the base, -2 if it is
19548 not a digit in any supported base. (Bug#8602)
19550 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
19552 * dispnew.c (scrolling_window): Return 1 if we scrolled,
19553 to match comment at start of function. This also removes a
19554 GCC warning about overflow in a 32+64-bit port.
19556 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
19558 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
19559 Reported by Stefan Monnier in
19560 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
19561 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19562 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
19564 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
19565 (EMACS_UINTPTR): Likewise, with uintptr_t.
19567 * lisp.h: Prefer 64-bit EMACS_INT if available.
19568 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
19569 on 32-bit hosts that have 64-bit int, so that they can access
19571 However, temporarily disable this change unless the temporary
19572 symbol WIDE_EMACS_INT is defined.
19574 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
19576 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
19577 This removes an assumption that EMACS_INT and long are the same
19578 width as pointers. The assumption is true for Emacs porting targets
19579 now, but we want to make other targets possible.
19580 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
19581 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
19582 In the rest of the code, change types of integers that hold casted
19583 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
19584 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
19585 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
19586 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
19587 No need to cast type when ORing.
19588 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
19589 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
19590 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
19591 assume EMACS_INT is the same width as char *.
19592 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
19593 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
19594 Remove no-longer-needed casts.
19595 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
19596 (xg_tool_bar_help_callback, xg_make_tool_item):
19597 Use EMACS_INTPTR to hold an integer
19598 that will be cast to void *; this can avoid a GCC warning
19599 if EMACS_INT is not the same width as void *.
19600 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
19601 * xdisp.c (display_echo_area_1, resize_mini_window_1):
19602 (current_message_1, set_message_1):
19603 Use a local to convert to proper width without a cast.
19604 * xmenu.c (dialog_selection_callback): Likewise.
19606 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
19607 Also, don't assume VALBITS / RAND_BITS is less than 5,
19608 and don't rely on undefined behavior when shifting a 1 left into
19610 * lisp.h (get_random): Change signature to match.
19612 * lread.c (hash_string): Use size_t, not int, for hash computation.
19613 Normally we prefer signed values; but hashing is special, because
19614 it's better to use unsigned division on hash table sizes so that
19615 the remainder is nonnegative. Also, size_t is the natural width
19616 for hashing into memory. The previous code used 'int', which doesn't
19617 retain enough info to hash well into very large tables.
19618 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
19620 * dbusbind.c: Don't possibly lose pointer info when converting.
19621 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
19622 Use XPNTR rather than XHASH, so that the high-order bits of
19623 the pointer aren't lost when converting through void *.
19625 * eval.c (Fautoload): Don't double-shift a pointer.
19627 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
19629 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
19631 * gnutls.c (DEF_GNUTLS_FN):
19632 * image.c (DEF_IMGLIB_FN): Make function pointers static.
19634 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
19636 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
19639 2011-05-05 Eli Zaretskii <eliz@gnu.org>
19641 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
19642 New version that can reserve upto 2GB of heap space.
19644 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
19646 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
19648 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
19650 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
19651 `gnutls_certificate_set_x509_key_file'.
19653 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
19655 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
19656 Update dependencies.
19658 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19660 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
19661 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
19662 Remove unused parameter `fildes'.
19663 * process.c (read_process_output, send_process): Don't pass it.
19665 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19667 Fix previous change: the library cache is defined in w32.c.
19668 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
19669 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
19671 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
19673 Implement dynamic loading of GnuTLS on Windows.
19675 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
19676 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
19677 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19680 * gnutls.c (Qgnutls_dll): Define.
19681 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
19682 (gnutls_*): Declare function pointers.

19686 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
19687 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
19688 (emacs_gnutls_write, emacs_gnutls_read)
19689 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
19690 (Fgnutls_available_p): New function.
19691 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
19692 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
19693 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
19695 * image.c: Include w32.h.
19696 (Vimage_type_cache): Delete.

19698 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
19699 (w32_delayed_load): Move to w32.c.
19701 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
19703 * w32.c (QCloaded_from, Vlibrary_cache): Define.
19704 (w32_delayed_load): Move from image.c. When loading a library, record
19705 its filename in the :loaded-from property of the library id.
19706 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
19707 Initialize and staticpro them.
19708 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
19710 * process.c: Include lisp.h before w32.h, not after.
19711 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
19712 instead of gnutls_record_check_pending.
19714 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
19716 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
19718 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
19719 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
19722 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
19724 * xterm.c (x_set_frame_alpha): Do not set property on anything
19725 else than FRAME_X_OUTER_WINDOW (Bug#8608).
19727 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19729 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
19731 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
19733 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
19734 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

19747 * sysdep.c (wait_for_termination_1): Make static.
19748 (wait_for_termination, interruptible_wait_for_termination):
19749 Move after wait_for_termination_1.
19751 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
19753 * sysdep.c (interruptible_wait_for_termination): New function
19754 which is like wait_for_termination, but allows keyboard
19757 * callproc.c (Fcall_process): Add (:file "file") as an option for
19759 (Fcall_process_region): Ditto.
19761 2011-04-30 Eli Zaretskii <eliz@gnu.org>
19763 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
19764 rather than `XVECTOR (FOO)->size'.
19766 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
19767 inttypes.h, as a gnulib replacement is used if it not available in
19770 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19772 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
19773 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
19774 of MOST_POSITIVE_FIXNUM. (Bug#8528)
19776 * coding.c (coding_alloc_by_realloc): Error out if destination
19777 will grow beyond MOST_POSITIVE_FIXNUM.
19778 (decode_coding_emacs_mule): Abort if there isn't enough place in
19779 charbuf for the composition carryover bytes. Reserve an extra
19780 space for up to 2 characters produced in a loop.
19781 (decode_coding_iso_2022): Abort if there isn't enough place in
19782 charbuf for the composition carryover bytes.
19784 2011-04-21 Eli Zaretskii <eliz@gnu.org>
19786 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
19787 aborting when %lld or %lll format is passed.
19788 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
19789 %llo or %llx format is passed. (Bug#8545)
19791 * window.c (window_scroll_line_based): Use a marker instead of
19792 simple variables to record original value of point. (Bug#7952)
19794 * doprnt.c (doprnt): Fix the case where a multibyte sequence
19795 produced by %s or %c overflows available buffer space. (Bug#8545)
19797 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
19799 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
19800 (SIZE_MAX): Move defn after all includes, as they might #define it.
19802 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19804 * w32.c (init_environment): Warn about defaulting HOME to C:\.
19806 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19808 * keyboard.c (Qdelayed_warnings_hook): Define.
19809 (command_loop_1): Run `delayed-warnings-hook'
19810 if Vdelayed_warnings_list is non-nil.
19811 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
19812 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
19814 2011-04-28 Eli Zaretskii <eliz@gnu.org>
19816 * doprnt.c (doprnt): Don't return value smaller than the buffer
19817 size if the message was truncated. (Bug#8545).
19819 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
19821 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
19822 (Fx_window_property): #if-0 the whole functions, not just the bodies.
19824 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19826 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
19828 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
19830 * makefile.w32-in: Update dependencies.
19832 2011-04-27 Eli Zaretskii <eliz@gnu.org>
19834 Improve `doprnt' and its usage. (Bug#8545)
19835 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
19836 `format_end'. Remove support for %l as a conversion specifier.
19837 Don't use xrealloc. Improve diagnostics when the %l size modifier
19838 is used. Update the commentary.
19840 * eval.c (verror): Simplify calculation of size_t.
19842 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
19845 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
19847 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
19850 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
19852 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
19853 This makes this file independent of the recent pseudovector change.
19855 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
19857 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
19859 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
19860 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
19861 Remove unused local.
19862 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
19864 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
19865 GCC 4.6.0 optimizes based on type-based alias analysis.
19866 For example, if b is of type struct buffer * and v of type struct
19867 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
19868 != &v->size, and therefore "v->size = 1; b->size = 2; return
19869 v->size;" must therefore return 1. This assumption is incorrect
19870 for Emacs, since it type-puns struct Lisp_Vector * with many other
19871 types. To fix this problem, this patch adds a new type struct
19872 vectorlike_header that documents the constraints on layout of vectors
19873 and pseudovectors, and helps optimizing compilers not get fooled
19874 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
19875 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
19876 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
19878 (XSETPVECTYPE): Rewrite in terms of new macro.
19879 (XSETPVECTYPESIZE): New macro, specifying both type and size.
19880 This is a bit clearer, and further avoids the possibility of
19881 undesirable aliasing.
19882 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
19883 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
19884 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
19885 since Lisp_Subr is a special case (no "next" field).
19886 (ASIZE): Now uses header.size rather than size.
19887 All previous uses of XVECTOR (foo)->size replaced to use this macro,
19888 to avoid the hassle of writing XVECTOR (foo)->header.size.
19889 (struct vectorlike_header): New type.
19890 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
19891 object, to help avoid aliasing.
19892 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
19893 (SUBRP): Likewise, since Lisp_Subr is a special case.
19894 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
19895 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
19896 (struct Lisp_Hash_Table): Combine first two members into a single
19897 struct vectorlike_header member. All uses of "size" and "next" members
19898 changed to be "header.size" and "header.next".
19899 * buffer.h (struct buffer): Likewise.
19900 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
19901 * frame.h (struct frame): Likewise.
19902 * process.h (struct Lisp_Process): Likewise.
19903 * termhooks.h (struct terminal): Likewise.
19904 * window.c (struct save_window_data, struct saved_window): Likewise.
19905 * window.h (struct window): Likewise.
19906 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
19907 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
19908 * buffer.c (init_buffer_once): Likewise.
19909 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
19911 * process.c (Fformat_network_address): Use local var for size,
19914 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
19916 Make the Lisp reader and string-to-float more consistent (Bug#8525)
19917 * data.c (atof): Remove decl; no longer used or needed.
19918 (digit_to_number): Move to lread.c.
19919 (Fstring_to_number): Use new string_to_number function, to be
19920 consistent with how the Lisp reader treats infinities and NaNs.
19921 Do not assume that floating-point numbers represent EMACS_INT
19922 without losing information; this is not true on most 64-bit hosts.
19923 Avoid double-rounding errors, by insisting on integers when
19924 parsing non-base-10 numbers, as the documentation specifies.
19925 * lisp.h (string_to_number): New decl, replacing ...
19926 (isfloat_string): Remove.
19927 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
19928 (read1): Do not accept +. and -. as integers; this
19929 appears to have been a coding error. Similarly, do not accept
19930 strings like +-1e0 as floating point numbers. Do not report
19931 overflow for integer overflows unless the base is not 10 which
19932 means we have no simple and reliable way to continue.
19933 Break out the floating-point parsing into a new
19934 function string_to_number, so that Fstring_to_number parses
19935 floating point numbers consistently with the Lisp reader.
19936 (digit_to_number): Move here from data.c. Make it static inline.
19937 (E_CHAR, EXP_INT): Remove, replacing with ...
19938 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
19939 (string_to_number): New function, replacing isfloat_string.
19940 This function checks for valid syntax and produces the resulting
19941 Lisp float number too. Rework it so that string-to-number
19942 no longer mishandles examples like "1.0e+". Use strtoumax,
19943 so that overflow for non-base-10 numbers is reported only when
19944 there's no portable and simple way to convert to floating point.
19946 * textprop.c (set_text_properties_1): Rewrite for clarity,
19947 and to avoid GCC warning about integer overflow.
19949 * intervals.h (struct interval): Use EMACS_INT for members
19950 where EMACS_UINT might cause problems. See
19951 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
19952 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
19953 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
19955 (offset_intervals): Tell GCC not to worry about length overflow
19956 when negating a negative length.
19958 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
19959 (overrun_check_free): Likewise.
19961 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
19962 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs

19971 * lread.c (openp): Don't stuff size_t into an 'int'.
19972 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
19973 about possible signed overflow.
19975 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
19976 (GDK_KEY_g): Don't define if already defined.
19977 (xg_prepare_tooltip): Avoid pointer signedness problem.
19978 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
19980 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
19981 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
19983 * xfns.c (Fx_window_property): Simplify a bit,
19984 to make a bit faster and to avoid GCC 4.6.0 warning.
19985 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
19987 * fns.c (internal_equal): Don't assume size_t fits in int.
19989 * alloc.c (compact_small_strings): Tighten assertion a little.
19991 Replace pEd with more-general pI, and fix some printf arg casts.
19992 * lisp.h (pI): New macro, generalizing old pEd macro to other
19993 conversion specifiers. For example, use "...%"pI"d..." rather
19994 than "...%"pEd"...".
19995 (pEd): Remove. All uses replaced with similar uses of pI.
19996 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
19997 * alloc.c (check_pure_size): Don't overflow by converting size to int.

20001 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20002 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20004 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20005 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20006 * print.c (safe_debug_print, print_object): Likewise.
20007 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20009 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20010 avoiding the 0 flag, which is not portable.

20012 * region-cache.c (pp_cache): Likewise.
20013 * xdisp.c (decode_mode_spec): Likewise.

20015 behavior on 64-bit hosts with printf arg.
20016 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
20017 (x_stop_queuing_selection_requests): Likewise.
20018 (x_get_window_property): Don't truncate byte count to an 'int'
20021 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20022 here, since it parses constructs like leading '-' and spaces,
20023 which are not wanted; and it overflows with large numbers.
20024 Instead, simply match F[0-9]+, which is what is wanted anyway.
20026 * alloc.c: Remove unportable assumptions about struct layout.
20027 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20028 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20029 (allocate_vectorlike, make_pure_vector): Use the new macros,
20030 plus offsetof, to remove unportable assumptions about struct layout.
20031 These assumptions hold on all porting targets that I know of, but
20032 they are not guaranteed, they're easy to remove, and removing them
20033 makes further changes easier.
20035 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20036 This doesn't fix a bug but makes the code clearer.
20037 (string_overrun_cookie): Now const. Use initializers that
20038 don't formally overflow signed char, to avoid warnings.
20039 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20040 can cause Emacs to crash when string overrun checking is enabled.
20041 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20042 multiple of sizeof (EMACS_INT); it need not be, if
20043 alignof(EMACS_INT) < sizeof (EMACS_INT).
20044 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
20046 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

20073 2011-04-25 Eli Zaretskii <eliz@gnu.org>
20075 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
20076 "cast to pointer from integer of different size".
20078 Improve doprnt and its use in verror. (Bug#8545)
20079 * doprnt.c (doprnt): Document the set of format control sequences
20080 supported by the function. Use SAFE_ALLOCA instead of always
20083 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20084 is one byte too soon. Don't use xrealloc; instead xfree and
20087 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
20089 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

20095 parameters of `gnutls-boot' and documented those parameters in the
20096 docstring. Start callback support.
20097 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20098 unless a fatal error occurred. Call gnutls_alert_send_appropriate

20176 conversions. Support %l conversion. Don't assume an EMACS_INT
20177 argument for integer conversions and for %c.
20179 * lisp.h (doprnt): Restore prototype.
20181 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

20202 codepoint of an invalid character, to avoid displaying a bogus
20205 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
20206 `error', not SYMBOL_NAME itself.

20211 * charset.c (check_iso_charset_parameter): Fix incorrect argument
20212 to `error' in error message about FINAL_CHAR argument. Make sure
20213 FINAL_CHAR is a character, and use %c when it is passed as
20214 argument to `error'.
20216 2011-04-23 Eli Zaretskii <eliz@gnu.org>
20218 * s/ms-w32.h (localtime): Redirect to sys_localtime.
20220 * w32.c: Include <time.h>.

20280 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
20281 by pacifying GCC about it. Maybe it's time to retire it?
20282 * xfaces.c (USG, __TIMEVAL__): Likewise.
20284 * dispextern.h (struct redisplay_interface): Rename param
20285 to avoid shadowing.
20286 * termhooks.h (struct terminal): Likewise.
20287 * xterm.c (xembed_send_message): Likewise.

20388 (group_in_compile_stack, re_search, re_search_2, regex_compile)
20389 (re_compile_pattern, re_exec): Declare arguments and local
20390 variables `size_t' and `ssize_t' and return values `regoff_t', as

20403 * nsfont.m: Fixed bugs in ns_get_family and
20404 ns_descriptor_to_entity that were caused by using free to
20405 deallocate memory blocks that were allocated by xmalloc (via
20406 xstrdup). This caused Emacs to crash when compiled with
20407 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
20408 --enable-checking=xmallocoverrun). xfree is now used to
20409 deallocate these memory blocks.
20411 2011-04-15 Paul Eggert <eggert@cs.ucla.edu>
20413 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

20423 (emacs_read, emacs_write): Remove check for negative size, as the
20424 Emacs source code has been audited now.
20425 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
20426 (emacs_read, emacs_write): Use it.
20427 * process.c (send_process): Adjust to the new signatures of
20428 emacs_write and emacs_gnutls_write. Do not attempt to store
20429 a byte offset into an 'int'; it might overflow.
20430 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

20849 (Funintern): Remove extern decl; now in .h file where it belongs.
20850 * fileio.c (Fmake_symbolic_link): New forward static decl.
20851 * image.c (Finit_image_library): New forward static decl.
20852 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
20853 * intervals.h (Fprevious_property_change):
20854 (Fremove_list_of_text_properties): Remove decls.
20855 * keyboard.c (Fthis_command_keys): Remove decl.

20877 2011-04-13 Eli Zaretskii <eliz@gnu.org>
20879 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
20880 when at ZV. (Bug#8487)
20882 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
20884 * charset.c (Fclear_charset_maps): Use xfree instead of free.
20886 * keyboard.c (parse_tool_bar_item): Likewise.
20887 * sound.c (sound_cleanup, alsa_close): Likewise.
20888 * termcap.c (tgetent): Likewise.
20889 * xfns.c (x_default_font_parameter): Likewise.
20890 * xsettings.c (read_and_apply_settings): Likewise.
20892 * alloc.c (overrun_check_malloc, overrun_check_realloc)
20893 (overrun_check_free): Protoize.
20895 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
20897 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
20898 since callers should never pass a negative size.
20899 Change the signature to match that of plain 'read' and 'write'; see
20900 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
20901 * lisp.h: Update prototypes of emacs_write and emacs_read.
20903 2011-04-11 Eli Zaretskii <eliz@gnu.org>
20905 * xdisp.c (redisplay_window): Don't try to determine the character
20906 position of the scroll margin if the window start point w->startp
20907 is outside the buffer's accessible region. (Bug#8468)
20909 2011-04-10 Eli Zaretskii <eliz@gnu.org>
20911 Fix write-region and its subroutines for buffers > 2GB.
20912 * fileio.c (a_write, e_write): Modify declaration of arguments and
20913 local variables to support buffers larger than 2GB.
20914 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
20916 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
20917 argument, local variables, and return value.
20919 * lisp.h: Update prototypes of emacs_write and emacs_read.
20921 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
20923 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
20925 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
20927 Fix more problems found by GCC 4.6.0's static checks.
20929 * xdisp.c (vmessage): Use a better test for character truncation.
20931 * charset.c (load_charset_map): <, not <=, for optimization,
20932 and to avoid potential problems with integer overflow.
20933 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
20934 * casetab.c (set_identity, shuffle): Likewise.
20935 * editfns.c (Fformat): Likewise.
20936 * syntax.c (skip_chars): Likewise.
20938 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
20939 This also lets GCC 4.6.0 generate slightly better loop code.
20941 * callint.c (Fcall_interactively): <, not <=, for optimization.
20942 (Fcall_interactively): Count the number of arguments produced,
20943 not the number of arguments given. This is simpler and lets GCC
20944 4.6.0 generate slightly better code.
20946 * ftfont.c: Distingish more carefully between FcChar8 and char.
20947 The previous code passed unsigned char * to a functions like
20948 strlen and xstrcasecmp that expect char *, which does not
20949 conform to the C standard.
20950 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
20951 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
20952 char * when the C standard requires it.
20954 * keyboard.c (read_char): Remove unused var.
20956 * eval.c: Port to Windows vsnprintf (Bug#8435).
20957 Include <limits.h>.
20958 (SIZE_MAX): Define if the headers do not.
20959 (verror): Do not give up if vsnprintf returns a negative count.
20960 Instead, grow the buffer. This ports to Windows vsnprintf, which
20961 does not conform to C99. Problem reported by Eli Zaretskii.
20962 Also, simplify the allocation scheme, by avoiding the need for
20963 calling realloc, and removing the ALLOCATED variable.
20965 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
20967 Remove invocations of doprnt, as Emacs now uses vsnprintf.
20968 But keep the doprint source code for now, as we might revamp it
20969 and use it again (Bug#8435).
20970 * lisp.h (doprnt): Remove.
20971 * Makefile.in (base_obj): Remove doprnt.o.
20972 * deps.mk (doprnt.o): Remove.
20974 error: Print 32- and 64-bit integers portably (Bug#8435).
20975 Without this change, on typical 64-bit hosts error ("...%d...", N)
20976 was used to print both 32- and 64-bit integers N, which relied on
20977 undefined behavior.
20978 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
20979 * lisp.h (error, verror): Mark as printf-like functions.
20980 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
20981 Report overflow in size calculations when allocating printf buffer.
20982 Do not truncate output string at its first null byte.
20983 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
20984 Truncate the output at a character boundary, since vsnprintf does not
20986 * charset.c (check_iso_charset_parameter): Convert internal
20987 character to string before calling 'error', since %c now has the
20989 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
20990 overflow when computing char to be passed to 'error'. Do not
20991 pass Lisp_Object to 'error'; pass the integer instead.
20992 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
20993 formatted with plain %d.
20995 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
20997 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
20999 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21001 * xterm.c (x_catch_errors): Remove duplicate declaration.
21003 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21005 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21007 2011-04-10 Jim Meyering <meyering@redhat.com>
21009 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21010 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21011 return ssize_t not "int", and use size_t as the buffer length.
21012 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21013 * gnutls.h: Update declarations.
21014 * process.c (read_process_output): Use ssize_t, to match.
21015 (send_process): Likewise.
21017 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21019 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21021 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21023 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21024 Use unsigned char, to match FcChar8 type definition.
21026 * xterm.c (handle_one_xevent):
21027 * xmenu.c (create_and_show_popup_menu):
21028 * xselect.c (x_decline_selection_request)
21029 (x_reply_selection_request): Avoid type-punned deref of X events.
21031 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21033 Fix some uses of `int' instead of EMACS_INT.
21034 * search.c (string_match_1, fast_string_match)
21035 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21036 (scan_buffer, find_next_newline_no_quit)
21037 (find_before_next_newline, search_command, Freplace_match)
21038 (Fmatch_data): Make some `int' variables be EMACS_INT.
21040 * xdisp.c (display_count_lines): 3rd argument and return value now
21041 EMACS_INT. All callers changed.
21042 (pint2hrstr): Last argument is now EMACS_INT.
21044 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21045 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21046 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21047 (decode_coding_utf_16, decode_coding_emacs_mule)

21049 (decode_coding_ccl, decode_coding_charset)
21050 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21051 (decode_coding_iso_2022, decode_coding_emacs_mule)
21052 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21053 <char_offset, last_offset>: Declare EMACS_INT.

21055 (encode_coding_emacs_mule, encode_invocation_designation)
21056 (encode_designation_at_bol, encode_coding_iso_2022)
21057 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21058 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21060 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21061 (encode_invocation_designation): Last argument P_NCHARS is now
21063 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21064 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21066 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21069 * ccl.c (Fccl_execute_on_string): Declare some variables
21072 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21074 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21076 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21078 * process.c (Fformat_network_address): Doc fix.
21080 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21082 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21084 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21086 * keyboard.c (read_char): Call Lisp function help-form-show,
21087 instead of using internal_with_output_to_temp_buffer.
21088 (Qhelp_form_show): New var.
21089 (syms_of_keyboard): Use DEFSYM macro.
21091 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21093 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21095 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21097 * process.c (Flist_processes): Remove to Lisp.
21098 (list_processes_1): Delete.
21100 2011-04-06 Eli Zaretskii <eliz@gnu.org>
21102 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21104 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21106 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21108 Fix more problems found by GCC 4.6.0's static checks.
21110 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
21112 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21114 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21116 * xdisp.c (vmessage): Mark as a printf-like function.
21118 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21120 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21122 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21123 printf-like functions.
21124 (tiff_load): Add casts to remove these marks before passing them
21125 to system-supplied API.
21127 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21129 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21130 This avoids several warnings with gcc -Wstrict-overflow.
21131 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21132 directly, rather than having caller test rule sign. This avoids
21133 some unnecessary tests.
21134 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21135 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21136 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21138 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21139 (xfont_open): Avoid unnecessary tests.
21141 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21143 * composite.h, composite.c (composition_gstring_put_cache):
21144 Use EMACS_INT, not int, for length.

21147 breaking out part of COMPOSITION_DECODE_RULE.
21148 (COMPOSITION_DECODE_RULE): Use it.

21150 by using the new macro.
21152 * textprop.c (set_text_properties_1): Change while to do-while,
21153 since the condition is always true at first.
21155 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21156 (interval_deletion_adjustment): Return unsigned value.
21159 * process.c (list_processes_1, create_pty, read_process_output):

21171 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21172 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21173 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21175 * print.c (print_error_message): Avoid int overflow.
21177 * font.c (font_list_entities): Redo for clarity,
21178 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
21180 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
21181 (font_score): Avoid potential overflow in diff calculation.
21183 * fns.c (substring_both): Remove var that is set but not used.
21184 (sxhash): Redo loop for clarity and to avoid wraparound warning.
21186 * eval.c (funcall_lambda): Rename local to avoid shadowing.
21188 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
21189 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
21190 can always succeed if overflow has undefined behavior.
21192 * search.c (boyer_moore, wordify): Remove vars set but not used.
21193 (wordify): Omit three unnecessary tests.
21195 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
21196 All callers changed. This avoids the need for an unused var.
21198 * casefiddle.c (casify_region): Remove var that is set but not used.
21200 * dired.c (file_name_completion): Remove var that is set but not used.
21202 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
21204 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
21205 (Finsert_file_contents): Remove unnecessary code checking fd.
21207 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
21208 Check for integer overflow on size calculations.
21210 * buffer.c (Fprevious_overlay_change): Remove var that is set
21213 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
21214 Remove vars that are set but not used.
21215 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
21216 (timer_check_2): Mark vars as initialized.
21218 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
21220 * image.c (lookup_image): Remove var that is set but not used.
21221 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
21223 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
21224 that are set but not used.
21226 * xfns.c (make_invisible_cursor): Don't return garbage
21227 if XCreateBitmapFromData fails (Bug#8410).
21229 * xselect.c (x_get_local_selection, x_handle_property_notify):
21230 Remove vars that are set but not used.
21232 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

21242 (map_tty_color) [!defined MSDOS]: Likewise.
21244 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
21246 * coding.c: Remove vars that are set but not used.
21247 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
21248 All callers changed.
21249 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
21250 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
21251 (decode_coding_charset): Remove vars that are set but not used.
21253 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
21254 that is set but not used.
21256 * print.c (print_object): Remove var that is set but not used.
21258 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
21259 The gnulib version avoids calling malloc in the usual case,
21260 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
21261 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
21262 * filelock.c (current_lock_owner): Likewise.
21263 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
21264 * sysdep.c: Include allocator.h, careadlinkat.h.
21265 (emacs_no_realloc_allocator): New static constant.
21266 (emacs_readlink): New function.
21267 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
21268 ../lib/careadlinkat.h.
21270 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
21272 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
21273 first non-nil return value).
21275 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
21277 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
21278 if not defined (Bug#8403).
21280 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21282 * xdisp.c (display_count_lines): Remove parameter `start',
21283 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21284 (get_char_face_and_encoding): Remove parameter `multibyte_p',
21285 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21287 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
21288 and thereabouts. All callers changed.
21289 (get_per_char_metric): Remove parameter `f', unused since
21290 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

21295 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
21296 (ns_get_family): Likewise.
21298 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
21300 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
21302 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
21304 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
21307 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
21309 Add lexical binding.
21311 * window.c (Ftemp_output_buffer_show): New fun.
21312 (Fsave_window_excursion):
21313 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
21315 * lread.c (lisp_file_lexically_bound_p): New function.
21316 (Fload): Bind Qlexical_binding.
21317 (readevalloop): Remove `evalfun' arg.
21318 Bind Qinternal_interpreter_environment.
21319 (Feval_buffer): Bind Qlexical_binding.
21320 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
21322 (syms_of_lread): Declare `lexical-binding'.
21324 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
21326 * keyboard.c (eval_dyn): New fun.
21327 (menu_item_eval_property): Use it.
21329 * image.c (parse_image_spec): Use Ffunctionp.
21331 * fns.c (concat, mapcar1): Accept byte-code-functions.
21333 * eval.c (Fsetq): Handle lexical vars.
21334 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
21335 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
21336 (FletX, Flet): Obey lexical binding.
21337 (Fcommandp): Handle closures.
21338 (Feval): New `lexical' arg.
21339 (eval_sub): New function extracted from Feval. Use it almost
21340 everywhere where Feval was used. Look up vars in lexical env.
21342 (Ffunctionp): Move from subr.el.
21343 (Ffuncall): Handle closures.
21344 (apply_lambda): Remove `eval_flags'.
21345 (funcall_lambda): Handle closures and new byte-code-functions.
21346 (Fspecial_variable_p): New function.
21347 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
21348 but without exporting it to Lisp.
21350 * doc.c (Fdocumentation, store_function_docstring):
21351 * data.c (Finteractive_form): Handle closures.
21353 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
21356 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
21358 (exec_byte_code): New function extracted from Fbyte_code to handle new
21359 calling convention for byte-code-functions. Add new byte-codes.
21361 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
21363 * alloc.c (Fmake_symbol): Init new `declared_special' field.
21365 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21367 * xdisp.c (redisplay_internal): Fix prototype.
21369 2011-03-31 Eli Zaretskii <eliz@gnu.org>
21371 * xdisp.c (SCROLL_LIMIT): New macro.
21372 (try_scrolling): Use it when setting scroll_limit.
21373 Limit scrolling to 100 screen lines.
21374 (redisplay_window): Even when falling back on "recentering",
21375 position point in the window according to scroll-conservatively,
21376 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
21378 (try_scrolling): When point is above the window, allow searching
21379 as far as scroll_max, or one screenful, to compute vertical
21380 distance from PT to the scroll margin position. This prevents
21381 try_scrolling from unnecessarily failing when
21382 scroll-conservatively is set to a value slightly larger than the
21383 window height. Clean up the case of PT below the margin at bottom
21384 of window: scroll_max can no longer be INT_MAX. When aggressive
21385 scrolling is in use, don't let point enter the opposite scroll
21386 margin as result of the scroll.
21387 (syms_of_xdisp) <scroll-conservatively>: Document the
21388 threshold of 100 lines for never-recentering scrolling.
21390 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
21392 * dispextern.h (move_it_by_lines):
21393 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
21394 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
21395 (message_log_check_duplicate): Remove parameters `prev_bol' and
21396 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
21397 (redisplay_internal): Remove parameter `preserve_echo_area',
21398 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
21400 * indent.c (Fvertical_motion):
21401 * window.c (window_scroll_pixel_based, Frecenter):
21402 Don't pass `need_y_p' to `move_it_by_lines'.
21404 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
21406 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
21407 steal a few bits to be more compact.
21408 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
21409 Remove unneeded casts.
21411 * bytecode.c (Fbyte_code): CAR and CDR can GC.
21413 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
21415 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
21416 binding" message (bug#7967).
21418 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
21420 Fix more problems found by GCC 4.6.0's static checks.
21422 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
21423 Remove unused local var.
21425 * editfns.c (Fmessage_box): Remove unused local var.
21427 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
21428 (note_mode_line_or_margin_highlight, note_mouse_highlight):
21429 Omit unused local vars.
21430 * window.c (shrink_windows): Omit unused local var.
21431 * menu.c (digest_single_submenu): Omit unused local var.
21432 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
21433 Omit unused local var.
21435 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
21436 Don't assume string length fits in int.
21437 (keyremap_step, read_key_sequence): Use size_t for sizes.
21438 (read_key_sequence): Don't check last_real_key_start redundantly.
21440 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
21441 instead of alloca (Bug#8344).
21443 * eval.c (Fbacktrace): Don't assume nargs fits in int.
21444 (Fbacktrace_frame): Don't assume nframes fits in int.
21446 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
21448 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
21451 * term.c (produce_glyphless_glyph): Remove unnecessary test.
21453 * cm.c (calccost): Turn while-do into do-while, for clarity.
21455 * keyboard.c (syms_of_keyboard): Use the same style as later
21456 in this function when indexing through an array. This also
21457 works around GCC bug 48267.
21459 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
21461 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
21463 * chartab.c (sub_char_table_ref_and_range): Redo for slight
21464 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
21466 * keyboard.c, keyboard.h (num_input_events): Now size_t.
21467 This avoids undefined behavior on integer overflow, and is a bit
21468 more convenient anyway since it is compared to a size_t variable.
21470 Variadic C functions now count arguments with size_t, not int.
21471 This avoids an unnecessary limitation on 64-bit machines, which
21472 caused (substring ...) to crash on large vectors (Bug#8344).
21473 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
21474 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

21480 (internal_condition_case_n, run_hook_with_args, apply_lambda)
21481 (funcall_lambda, mark_backtrace): Likewise.
21482 * fns.c (concat): Likewise.
21483 * frame.c (x_set_frame_parameters): Likewise.
21484 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
21485 0 if not found, not -1. All callers changed.
21487 * alloc.c (garbage_collect): Don't assume stack size fits in int.
21488 (stack_copy_size): Now size_t, not int.
21489 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
21491 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
21493 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

21497 * lisp.h (multibyte_char_to_unibyte):
21498 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
21499 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

21509 * keyboard.c (safe_run_hook_funcall): New function.
21510 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
21511 don't set the hook to nil, but remove the offending function instead.
21512 (Qcommand_hook_internal): Remove, unused.
21513 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
21514 Vcommand_hook_internal.
21516 * eval.c (enum run_hooks_condition): Remove.
21517 (funcall_nil, funcall_not): New functions.
21518 (run_hook_with_args): Call each function through a `funcall' argument.
21519 Remove `cond' argument, now redundant.
21520 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
21521 (Frun_hook_with_args_until_failure): Adjust accordingly.
21522 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

21528 * print.c (strout): Remove parameter `multibyte', unused since
21529 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
21531 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
21532 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
21533 All callers changed.
21535 * w32.c (_wsa_errlist): Use braces for struct initializers.

21545 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
21546 All callers changed.
21548 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
21550 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

21590 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
21592 * keyboard.c (timer_check): Remove parameter `do_it_now',
21593 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
21594 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
21595 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.

21598 * w32menu.c (w32_menu_display_help):
21599 * xmenu.c (show_help_event, menu_help_callback):
21600 Adjust calls to `show_help_echo'.
21602 * gtkutil.c (xg_maybe_add_timer):
21603 * keyboard.c (readable_events):
21604 * process.c (wait_reading_process_output):
21605 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.

21694 * buffer.c (Fkill_all_local_variables):
21695 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
21697 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
21698 unconditionally since it does the check itself.
21700 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
21702 Fix more problems found by GCC 4.5.2's static checks.
21704 * coding.c (encode_coding_raw_text): Avoid unnecessary test
21705 the first time through the loop, since we know p0 < p1 then.
21706 This also avoids a gcc -Wstrict-overflow warning.
21708 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
21709 leading to a memory leak, possible in functions like
21710 load_charset_map_from_file that can allocate an unbounded number
21711 of objects (Bug#8318).
21713 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
21714 that could (at least in theory) be that large.
21716 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
21717 This is less likely to overflow, and avoids undefined behavior if
21718 overflow does occur. All callers changed. Use strtoul to scan
21719 for the unsigned long integer.
21720 (pint2hrstr): Simplify and tune code slightly.
21721 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
21723 * scroll.c (do_scrolling): Work around GCC bug 48228.
21724 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
21726 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
21727 This also avoids a warning with gcc -Wstrict-overflow.
21728 (validate_x_resource_name): Simplify count usage.
21729 This also avoids a warning with gcc -Wstrict-overflow.
21731 * fileio.c (Fcopy_file): Report error if fchown or fchmod
21734 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
21736 * process.c (Fmake_network_process): Use socklen_t, not int,
21737 where POSIX says socklen_t is required in portable programs.
21738 This fixes a porting bug on hosts like 64-bit HP-UX, where
21739 socklen_t is wider than int (Bug#8277).
21740 (Fmake_network_process, server_accept_connection):
21741 (wait_reading_process_output, read_process_output):

21756 Include tparam.h instead, since it declares them.
21757 * cm.h (PC): Remove extern decl; tparam.h now does this.
21758 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
21759 * terminfo.c: Include tparam.h, to check interfaces.
21760 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
21761 (tparam): Adjust signature to match interface in tparam.h;
21762 this removes some undefined behavior. Check that outstring and len
21763 are zero, which they always are with Emacs.
21764 * tparam.h (PC, BC, UP): New extern decls.
21766 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

21808 (wav_play): Initialize a variable to 0, to prevent undefined
21809 behavior (Bug#8278).

21813 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
21815 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
21816 clobbering (Bug#8298).
21817 * sysdep.c (sys_subshell): Likewise.
21818 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
21820 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
21821 This should get cleaned up, so that child_setup has the
21822 same signature on all platforms.
21824 * callproc.c (call_process_cleanup): Now static.
21825 (relocate_fd): Rename locals to avoid shadowing.
21827 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
21829 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
21830 not to be necessary, and produces flickering.

21883 * unexelf.c (unexec): Name an expression,
21884 to avoid gcc -Wbad-function-cast warning.
21885 Use a different way to cause a compilation error if anyone uses
21886 n rather than nn, a way that does not involve shadowing.
21887 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
21889 * deps.mk (unexalpha.o): Remove; unused.

21985 (GC_STRING_CHARS): Remove; not used.
21986 (Fmemory_limit): Cast sbrk's returned value to char *.
21988 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

21994 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
21995 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
21996 to use the following functions instead of these macros.
21997 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
21998 EMACS_INT, since callers assume the returned value fits in int.
21999 (upcase1): Likewise, for UPCASE_TABLE.
22000 (uppercasep, lowercasep, upcase): New static inline functions.
22001 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22011 (regex_compile, re_match_2_internal): Mark locals as initialized.
22012 (RETALLOC_IF): Define only if needed.
22013 (WORDCHAR_P): Likewise. This one is never needed, but is used
22014 only in a comment talking about a compiler bug, so put inside
22015 the #if 0 of that comment.
22016 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22017 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22043 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
22044 New macros, so that the caller can use some names other than
22045 gcpro1, gcpro2, etc.
22046 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22048 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22049 argument, for consistency with GCPRO2_VAR, etc: it is now the
22050 prefix of the variable, not the variable itself. All uses
22052 * dired.c (directory_files_internal, file_name_completion):
22053 Rename locals to avoid shadowing.
22055 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22056 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22057 dired.c's scmp function, had undefined behavior.
22058 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22059 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22060 * buffer.h: ... to here, because these macros use current_buffer,
22061 and the new implementation with inline functions needs to have
22062 current_buffer in scope now, rather than later when the macros
22064 (downcase, upcase1): New static inline functions.
22065 (DOWNCASE, UPCASE1): Reimplement using these functions.
22066 This avoids undefined behavior in expressions like
22067 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22068 from race conditions in accessing the global variables
22069 case_temp1 and case_temp2.
22070 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22071 * lisp.h (case_temp1, case_temp2): Remove their decls.
22072 * character.h (ASCII_CHAR_P): Move from here ...
22073 * lisp.h: ... to here, so that the inline functions mentioned
22074 above can use them.
22076 * dired.c (directory_files_internal_unwind): Now static.
22078 * fileio.c (file_name_as_directory, directory_file_name):

22081 (file_name_as_directory): Use const pointers when appropriate.
22082 (Fexpand_file_name): Likewise. In particular, newdir might
22083 point at constant storage, so make it a const pointer.
22084 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
22085 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22087 (Fset_file_times, Finsert_file_contents, auto_save_error):

22092 to avoid shadowing.
22094 * marker.c (bytepos_to_charpos): Remove; unused.
22096 * lisp.h (verify_bytepos, count_markers): New decls,
22097 so that gcc does not warn that these functions aren't declared.
22099 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22100 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22101 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22102 (copy_text): Remove unused local var.

22107 * buffer.c (fix_overlays_before): Mark locals as initialized.
22108 (fix_start_end_in_overlays): Likewise. This function should be
22109 simplified by using pointers-to-pointers, but that's a different
22111 (switch_to_buffer_1): Now static.
22112 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22113 (report_overlay_modification): Rename locals to avoid shadowing.

22116 Fix pointer signedness issue.
22117 (sys_subshell): Mark local as volatile if checking for lint,
22118 to suppress a gcc -Wclobbered warning that does not seem to be right.
22119 (MAXPATHLEN): Define only if needed.
22121 * process.c (serial_open, serial_configure): Move decls from here ...
22122 * systty.h: ... to here, so that they can be checked.
22124 * fns.c (get_random, seed_random): Move extern decls from here ...
