3 * regex.c: Fix problems when DEBUG is defined.
4 (extract_number, extract_number_and_incr): Define regardless of
5 whether DEBUG is defined; that's simpler and makes the code less
6 likely to go stale in the normal case when DEBUG is not defined.
7 Return int rather than taking an int * arg. All callers changed.

11 (DEBUG_COMPILES_ARGUMENTS): New macro.
12 (print_fastmap, print_partial_compiled_pattern) [DEBUG]:

15 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
16 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
17 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
18 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
19 Don't assume ptrdiff_t, size_t, and long are the same width as int.
20 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
21 This matters only when DEBUG is defined.
23 2013-05-05 Eli Zaretskii <eliz@gnu.org>
25 * xdisp.c (set_iterator_to_next): Set the
26 ignore_overlay_strings_at_pos_p flag only if we are _really_
27 iterating over an overlay string, as indicated by the
28 current.overlay_string_index member. (Bug#14306)
30 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
32 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle

38 * fileio.c (syms_of_fileio): Implement this.
39 * filelock.c (create_lock_file): If symbolic links don't work, so
40 we use a regular file as a lock file, do not fsync the lock file;

114 * w32fns.c (w32_fullscreen_rect): New function to compute the
115 window rectangle for the given fullscreen mode.
116 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
117 longer tunes the window size. This keeps the window's edges flush
118 with the screen and allows the taskbar to hide itself in fullboth.
120 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
121 window decorations and uses the entire screen.
123 * w32term.h (w32_fullscreen_rect) Add prototype.
124 (struct w32_output): Replace normal_width, normal_height,
125 normal_top, and normal_left members with a single normal_placement

150 * keyboard.c (timer_start_idle): Remove no-longer-used local.
152 2013-04-14 Eli Zaretskii <eliz@gnu.org>
154 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
155 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
156 Mention in the doc string that setting these variables takes
157 effect only after a call to set-window-buffer. (Bug#14200)
159 2013-04-13 Eli Zaretskii <eliz@gnu.org>
161 * indent.c (Fvertical_motion): Don't consider display strings on
162 overlay strings as display strings on the buffer position we
163 started from. This prevents vertical cursor motion from jumping
164 more than one line when there's an overlay string with a display
165 property at end of line.
166 Reported by Karl Chen <Karl.Chen@quarl.org> in
167 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

172 already selected (bug#14191).
174 2013-04-11 Eli Zaretskii <eliz@gnu.org>
176 * window.c (Fwindow_end): Test more flags, including the buffer's
177 last_overlay_modified flag, to determine whether the window's
178 display is really up-to-date. Prevents the function from
179 returning a stale value. (Bug#14170)
180 (Fwindow_line_height): Fix the test for up-to-date-ness of the
183 2013-04-10 Eli Zaretskii <eliz@gnu.org>
185 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
186 garbaged only if it is not already the top frame on its TTY.
187 This prevents flickering due to constant redrawing of TTY frames when
188 there are GUI frames open in the same session. (Bug#13864)
190 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
192 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
193 of marking the idle timers directly.

217 2013-03-31 Jan Djärv <jan.h.d@swipnet.se>
219 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
222 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
224 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
225 This bug was introduced by my 2013-02-25 change that simplified
226 data_start configuration. Without this change, on GNU/Linux
227 an Emacs configured with --enable-profiling fails immediately
228 due to a profiler signal.
229 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
230 with these flags. On platforms where special flags are needed
231 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
232 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
233 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
235 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>

307 Prefer < to > in range checks such as 0 <= i && i < N.
308 This makes it easier to visualize quantities on a number line.
309 This patch doesn't apply to all such range checks,
310 only to the range checks affected by the 2013-03-24 change.
311 This patch reverts most of the 2013-03-24 change.

440 Use contents slot, not buffer, where appropriate.
441 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
442 to avoid deleted windows. Use contents slot instead of buffer.
443 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
444 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:
445 * nsfns.m, nsmenu.m, nsterm.m, print.c, w32fns.c, w32menu.c, xfaces.c:

463 (unwind_with_echo_area_buffer): ...to restore it here.
464 This is needed to ensure that...
465 (redisplay_window): ...both window markers are valid here,
466 which is verified by eassert.
467 * editfns.c (save_excursion_save): Do not assume that
468 selected_window always displays the buffer.
469 * buffer.c (Fbuffer_swap_text): Adjust window start markers.

627 'fullscreen' parameter. Always record previous width and height
628 of the frame, except when switching out of maximized modes, so
629 that they could be restored correctly, instead of resetting to the
630 default frame dimensions. Send SC_RESTORE command to the frame,
631 unless we are going to send SC_MAXIMIZE, to restore the frame
632 resize hints in the mouse pointer shown by the window manager.

666 * alloc.c: Verify some properties of Lisp_Save_Value's representation.
667 (make_save_value): Change 1st arg from string to enum. All callers
670 (mark_object): Use if, not #if, for GC_MARK_STACK.

681 type3 with a single member save_type. All uses changed.
682 (save_type, set_save_pointer, set_save_integer): New functions.
683 * print.c (PRINTX): Remove.

780 * coding.c (detect_ascii): New function.
781 (detect_coding): Set coding->head_ascii and coding->eol_seen only
782 when the source bytes are actually scanned. On detecting for
783 coding_category_utf_8_auto, call detect_ascii instead of scanning
784 source bytes directly.
785 (produce_chars): Call insert_from_gap with the new arg 0.
786 (encode_coding): Likewise.
787 (decode_coding_gap): Control ASCII optimization by the variable

820 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
821 too so that these builds can use Cygwin's file conversion
822 functions. (We've been building and linking cygw32.o all along
823 and just not using it.)
825 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

839 activated, call w32fullscreen_hook, to make sure the new frame
840 dimensions are in effect. (Bug#13937)
842 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
844 * xdisp.c (init_iterator): Simplify because both character and byte
845 positions are either specified or -1. Add eassert. Adjust comment.
846 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
847 character and byte positions can be obtained from marker.

867 Include <sys/param.h> unconditionally, as that works elsewhere and
868 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
869 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

876 2013-03-11 Stefan Monnier <monnier@iro.umontreal.ca>

983 * editfns.c (Fconstrain_to_field): Break long line.
984 Adjust call to find_newline.
985 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

1010 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1012 * bidi.c (bidi_fetch_char): Swap first and second arguments
1013 to match other functions accepting character and byte positions.
1015 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
1016 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
1017 when you need just to move to the previous buffer position.
1018 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1020 2013-03-07 Eli Zaretskii <eliz@gnu.org>
1022 * .gdbinit (prowlims): Display the enabled_p flag of the row.
1024 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>

1039 (Frecenter): Adjust calls to vmotion.
1041 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
1043 * lisp.h (list2i, list3i): New functions.

1090 (decode_coding_object): Simplify since xrealloc never returns NULL.
1093 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1095 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1096 * sysdep.c (list_system_processes)
1097 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1098 Make it a stub in this case; otherwise the build might fail,
1099 and this code hasn't been tested on such hosts anyway.
1100 Problem reported by Nelson H. F. Beebe in
1101 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1102 and analyzed by Jérémie Courrèges-Anglas in
1103 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1105 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1107 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1108 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1109 (get_visually_first_element, move_it_vertically_backward): Ajust users.

1113 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1115 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1116 * filelock.c: Include <c-ctype.h>.
1117 (MAX_LFINFO): New top-level constant.
1118 (lock_info_type): Remove members pid, boot_time. Add members at,
1119 dot, colon. Change user member to be the entire buffer, not a
1120 pointer. This allows us to handle the case where a foreign
1121 pid or boot time exceeds the local range. All uses changed.
1122 (LINKS_MIGHT_NOT_WORK): New constant.
1123 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1124 (defined_WINDOWSNT): Remove.
1125 (MAKE_LOCK_NAME, file_in_lock_file_name):
1126 Always use .#FILE (not .#-FILE) for the file lock,
1127 even if it is a regular file.
1128 (rename_lock_file): New function.
1129 (create_lock_file): Use it.
1130 (create_lock_file, read_lock_data):
1131 Prefer a symbolic link for the lock file, falling back on a
1132 regular file if symlinks don't work. Do not try to create
1133 symlinks on MS-Windows, due to security hassles. Stick with
1134 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1135 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1136 host may be using a Windowsish file system, and cannot use
1137 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1138 doesn't work. Don't fail merely because of a symlink-contents
1139 length limit in the current file system; fall back on regular
1140 files. Increase the symlink contents length limit to 8 KiB, this
1141 should be big enough for any real use and doesn't crunch the
1143 (create_lock_file, lock_file_1, read_lock_data):
1144 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1145 (lock_file_1): Return error number, not bool. All callers changed.
1146 (ELOOP): New macro, if not already defined.
1147 (read_lock_data): Return size of lock file contents, not Lisp object.
1148 All callers changed. Handle a race condition if some other process
1149 replaces a regular-file lock with a symlink lock or vice versa,
1150 while we're trying to read the lock.
1151 (current_lock_owner): Parse contents more carefully, to help avoid
1152 confusing a regular-file lock with some other application's use
1153 of the file. Check for lock file contents being too long, or
1154 not parsing correctly.
1155 (current_lock_owner, lock_file):
1156 Allow foreign pid and boot times that exceed the local range.
1157 (current_lock_owner, lock_if_free, lock_file):
1158 Simplify allocation of lock file contents.
1159 * w32.c (sys_rename_replace): New function, containing most of
1160 the contents of the old sys_rename.
1161 (sys_rename): Use it.
1162 (fchmod): New dummy function.
1163 * w32.h (sys_rename_replace, fchmod): New decls.
1165 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1167 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1168 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1169 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1170 <dmantipov@yandex.ru>.
1172 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1174 * composite.c (get_composition_id, fill_gstring_header):
1175 Use make_uninit_vector where appropriate.
1176 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1177 * xselect.c (clean_local_selection_data): Likewise.
1179 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1181 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1182 * image.c (imagemagick_load_image): Calculate height and width
1183 after flattening the image, not before.
1185 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1187 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1188 * ftfont.c (ftfont_shape_by_flt): Likewise.
1189 * w32uniscribe.c (uniscribe_shape): Likewise.
1191 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1193 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1194 The old approach, which fell back on DIR/.#FILE.0 through
1195 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1196 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1197 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1198 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1199 because the locking mechanism was never reliable in that case).
1200 This patch fixes this and other bugs discovered by a code
1201 inspection that was prompted by
1202 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1203 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1204 to avoid interoperability problems between the MS-Windows and
1205 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1206 instances of Emacs now ignore each others' locks.
1207 * filelock.c (defined_WINDOWSNT): New constant.
1208 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1209 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1210 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1211 regular files on MS-Windows hosts.
1212 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1213 Use SAFE_ALLOCA to avoid problems with long file names.
1214 (MAX_LFINFO): Now a local constant, not a global macro.
1215 (IS_LOCK_FILE): Remove.
1216 (lock_file_1): Don't inspect errno if symlink call succeeds;
1217 that's not portable.
1218 (lock_file): Document that this function can return if lock
1220 (lock_file): Don't access freed storage.
1222 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1224 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1226 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1228 * textprop.c: Use bool for booleans.
1229 (validate_interval_range, Fadd_text_properties)
1230 (Fremove_text_properties): Prefer bool to int when either works.
1232 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1234 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1235 If the interval tree changes as a side effect of calling
1236 modify_region, re-do processing starting from the call to
1237 validate_interval_range. (Bug#13743)
1239 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1241 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1244 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1246 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1247 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1248 access to the lock file until it is written and closed.
1251 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1253 * callint.c (Qcall_interactively):
1254 * macros.c (Qexecute_kbd_macro):
1257 2013-02-26 Bastien Guerry <bzg@gnu.org>
1259 * window.c (Frecenter): Tiny docstring enhancement.
1261 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1263 Minor textprop integer cleanup.
1264 * intervals.h, textprop.c (add_text_properties_from_list):
1265 Return void, not int, since nobody uses the return value.
1266 * textprop.c (validate_plist, add_properties, remove_properties)
1267 (Fadd_text_properties):
1268 Don't assume list length fits in int.
1269 (interval_has_all_properties, interval_has_some_properties)
1270 (interval_has_some_properties_list, add_properties, remove_properties)
1271 (Fadd_text_properties, Fremove_text_properties)
1272 (Fremove_list_of_text_properties, text_property_stickiness):
1273 Use bool for booleans.
1274 (Fadd_text_properties, Fremove_text_properties):
1275 (Fremove_list_of_text_properties):
1276 Reindent do-while as per GNU style.
1278 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1280 Implement CLASH_DETECTION for MS-Windows.
1282 * filelock.c [WINDOWSNT]: Include w32.h.
1283 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1284 function of that name. Up-case the macro arguments.
1285 (IS_LOCK_FILE): New macro.
1286 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1287 (create_lock_file): New function, with body extracted from
1289 [WINDOWSNT]: Implement lock files by writing a regular file with
1290 the lock information as its contents.
1291 (read_lock_data): New function, on Posix platforms just calls
1293 [WINDOWSNT]: Read the lock info from the file.
1294 (current_lock_owner): Call read_lock_data instead of calling
1295 emacs_readlinkat directly.
1296 (lock_file) [WINDOWSNT]: Run the file name through
1299 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1300 just check if the process by that PID exists.
1302 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1303 also present, as doing so will fail to error out if the file
1306 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1308 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1309 (Fremove_list_of_text_properties): Skip all of the intervals in
1310 the region between START and END that already have resp. don't
1311 have the requested properties, not just the first one.
1312 Add assertions that the loop afterwards always modifies the
1313 properties. (Bug#13743)
1315 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1317 * callint.c (Fcall_interactively): Use the right lexical environment
1318 for `interactive' specs (bug#13811).

1325 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
1326 (START_FILES): Remove. All uses removed.
1327 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.

1342 (make_hdr): Use DATA_START instead of start_of_data.
1343 * vm-limit.c: Move most of mem-limits.h's contents here.
1344 (data_start): New decl. It's OK if this is approximate,
1345 so simplify-away some unnecessary exactness.
1346 (POINTER): Remove; all uses removed.
1347 (data_space_start): Now char *, to avoid casts.
1348 (exceeds_lisp_ptr): New function, replacing the old
1349 EXCEEDS_LISP_PTR macro. All uses changed.

1363 2012-07-10 patch to this file. Reported by Eli Zaretskii in
1364 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
1365 and diagnosed by Andreas Schwab in

1368 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1370 Assume C89 or better.
1371 * ralloc.c (SIZE, POINTER, NIL):
1372 * vm-limit.c (POINTER):
1373 Remove, replacing all uses with C89 equivalents. These old
1374 symbols were present only for porting to pre-C89 platforms.
1376 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1378 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1379 This avoids warning messages reported as part of Bug#13546.

1394 2013-02-19 Daniel Colascione <dancol@dancol.org>
1396 * sheap.c (report_sheap_usage): Use message, not message1, so
1397 that we don't try to create a buffer while we're in the middle
1398 of dumping Emacs. Explain why.

1417 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1418 resources were not orderly released.
1420 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1422 * xdisp.c (x_draw_vertical_border): For a window that is neither
1423 the leftmost nor the rightmost, redraw both the left and the right
1424 vertical borders. (Bug#13723)

1439 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
1441 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...

1444 2013-02-16 Eli Zaretskii <eliz@gnu.org>
1446 * w32.c (sys_chown): Remove unused function.
1448 * w32term.c <input_signal_count>: Declare 'volatile'
1449 unconditionally. (Bug#9066)
1451 * w32.c (set_errno): Reset h_errno and don't set it to any other
1452 value. Set errno instead.
1453 (check_errno): Reset h_errno.
1454 (sys_socket, socket_to_fd, sys_bind, sys_connect)

1461 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1463 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
1465 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1467 * keyboard.c (read_char): Fix calculation of auto-save time out
1468 when auto-save-timeout is less than 4. (Bug#13720)
1470 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1471 time. Improve diagnostics in DebPrint. (Bug#13546)

1477 make sure errno is set to an appropriate value. (Bug#13546)
1478 (socket_to_fd): Add assertion against indexing fd_info[] with a
1479 value that is out of bounds.
1480 (sys_accept): If fd is negative, do not set up the child_process
1481 structure for reading.
1483 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1485 * composite.c (fill_gstring_header): Remove useless prototype.

1497 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1499 Fix AIX port (Bug#13650).
1500 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1501 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1502 was #undeffed earlier, so it cannot be used as a macro here.
1503 Use the constant and not the macro.
1505 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1507 * w32proc.c (new_child): If no vacant slots are found in
1508 child_procs[], make another pass looking for slots whose process
1509 has exited or died. (Bug#13546)
1511 * w32.c (sys_pipe): When failing due to file descriptors above
1512 MAXDESC, set errno to EMFILE.
1513 (_sys_read_ahead): Update cp->status when failing to read serial
1514 communications input, so that the status doesn't stay at
1515 STATUS_READ_IN_PROGRESS. (Bug#13546)
1517 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1519 * gtkutil.c (tb_size_cb): New function.

1522 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1524 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not

1539 2013-02-13 Glenn Morris <rgm@gnu.org>
1541 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1543 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1545 Improve AIX port some more (Bug#13650).
1546 With this, it should be as good as it was in 23.3, though it's
1547 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1548 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1549 * unexaix.c (start_of_text): Remove.
1550 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1551 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1552 (orig_load_scnptr, orig_data_scnptr):
1553 Now off_t, not long, since they are file offsets.
1554 (make_hdr): Use _data, not start_of_data ().
1555 This is the key part of the fix.
1556 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1557 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1559 * pre-crt0.c (data_start): Initialize to 1.
1560 This ports to compilers that optimize the external declaration
1561 'int x = 0;' as if it were 'int x;' to shrink the executable.
1563 Improve AIX port (Bug#13650).
1564 This doesn't fix the bug, but it makes progress: Emacs builds now.
1565 * unexaix.c: Include inttypes.h, stdarg.h.
1566 (report_error, report_error_1): Mark as _Noreturn.
1567 (report_error): Don't report the wrong errno.
1568 (report_error_1): Now varargs. All callers changed.
1569 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1570 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1571 (write_ptr): Use %p to print address rather than %lx and a cast
1572 to unsigned long. Grow buffer a bit, to be safer.
1574 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1576 * bidi.c (bidi_resolve_neutral): After finding the next
1577 non-neutral character, accept NEUTRAL_ON type as well, because
1578 directional control characters, such as LRE and RLE, have their
1579 type converted to that by bidi_resolve_weak. This avoids aborts
1580 when LRE/RLE follows a run of neutrals.
1581 (bidi_move_to_visually_next): Assert that return value of
1582 bidi_peek_at_next_level is non-negative. Negative values will
1585 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1587 Minor getenv-related fixes.
1588 * callproc.c (Fcall_process_region) [!DOS_NT]:
1589 Avoid unnecessary duplicate call to getenv.
1590 * callproc.c (init_callproc):
1591 * dispnew.c (init_display):
1592 * sysdep.c (sys_subshell):
1593 Omit unnecessary cast of getenv or egetenv.
1595 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1597 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1598 Update dependencies.
1600 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1602 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1604 (display_line): Set w->region_showing to the value of
1605 it->region_beg_charpos, not to -1. This fixes redisplay
1606 optimization when cursor is moved up after M->. (Bug#13623)
1608 (try_scrolling): Scroll text up more if point is too close to ZV
1609 and inside the scroll margin. This makes sure point is moved
1610 outside the scroll margin in these cases.
1612 * window.h (struct window): region_showing can no longer be
1615 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1617 Tune by using memchr and memrchr.
1618 * doc.c (Fsnarf_documentation):
1619 * fileio.c (Fsubstitute_in_file_name):
1620 * search.c (find_newline, scan_newline):
1621 * xdisp.c (pos_visible_p, display_count_lines):
1622 Use memchr and memrchr rather than scanning byte-by-byte.
1623 * search.c (find_newline): Rename from scan_buffer.
1624 Omit first arg TARGET, as it's always '\n'. All callers changed.
1626 Clean up read_key_sequence a tiny bit more.
1627 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1628 (read_key_sequence): Remove unused locals.
1630 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1632 Clean up read_key_sequence a bit; reread active keymaps after first event.
1633 * keyboard.c (read_char, read_char_x_menu_prompt)
1634 (read_char_minibuf_menu_prompt):
1635 Replace nmaps+maps with a single `map' arg.
1636 (follow_key): Operate on a single map.
1637 (active_maps): New function.
1638 (test_undefined): Also return true for nil bindings.
1639 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1640 a single (composed) keymap. Remember `first_event' to choose the right
1641 set of active keymaps. Recompute the set of keymaps after receiving
1642 the first event. Remove GOBBLE_FIRST_EVENT.
1643 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1644 * keyboard.h (read_char): Update declaration.
1645 * lread.c (read_filtered_event): Adjust call to read_char.
1647 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1649 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1650 Don't use the limitation on backwards movement when lines are truncated
1651 in the window. (Bug#13675)
1653 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1655 * marker.c (set_marker_internal): If desired position is passed
1656 as a marker, avoid call to buf_charpos_to_bytepos.
1657 * window.c (Fset_window_point): Omit redundant type checking.
1658 (Fset_window_start): Likewise. Format comment.
1659 (window_scroll_pixel_based): Use set_marker_restricted_both
1660 with character and byte positions obtained from an iterator.
1661 (Fset_window_configuration): Use set_marker_restricted_both.
1662 * xdisp.c (message_dolog): Likewise.
1664 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1666 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1667 When text lines are longer than window's screen lines, don't move back
1668 too far. This speeds up some redisplay operations. (Bug#13675)
1670 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1672 * syntax.c (scan_sexps_forward): Fix byte position calculation
1673 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1675 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1677 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1678 that was not needed.
1680 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1682 Minor hashing refactoring.
1683 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1684 (sxhash_float): Return EMACS_UINT, for consistency with the other
1686 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1687 non-static inline function and therefore can't use static vars.
1688 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1689 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1690 with the other hash functions.
1692 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1694 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1695 XXXXXX part of the temporary file pattern is not downcased even
1696 when w32-downcase-file-names is non-nil. (Bug#13661)
1698 * xdisp.c (decode_mode_spec): Remove handling of %t.
1700 * msdos.c (careadlinkatcwd): Remove.
1702 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1704 * lread.c (skip_dyn_bytes): New function (bug#12598).
1705 (read1): Use it. Use getc instead of READCHAR to read bytes.
1706 (load_each_byte): Remove. Update users.
1708 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1710 * search.c (scan_buffer): Calculate end byte position just once.

1713 * syntax.c (struct lisp_parse_state): New member location_byte.
1714 (scan_sexps_forward): Record from_byte and avoid redundant
1715 character to byte position calculation ...
1716 (Fparse_partial_sexp): ... here. Break too long line.
1718 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1720 * lisp.h (make_uninit_vector): New function.
1721 * alloc.c (Fvector, Fmake_byte_code):
1722 * ccl.c (Fregister_ccl_program):
1723 * charset.c (Fdefine_charset_internal, define_charset_internal):

1733 * window.c (Fcurrent_window_configuration):
1734 * xfaces.c (Fx_family_fonts):
1735 * xselect.c (selection_data_to_lisp_data): Use it.
1737 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
1739 * coding.c (Fdefine_coding_system_internal): Use AREF where
1740 argument is known to be a vector.
1741 * fns.c (Flocale_info): Likewise for ASET.
1742 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1743 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1745 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1747 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1750 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1751 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
1752 updateCollectionBehaviour.
1754 * nsterm.m (NEW_STYLE_FS): Remove.
1755 (ns_last_use_native_fullscreen): New variable.
1756 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1757 (x_set_window_size): Do not take title bar and tool bar into account
1758 if isFullscreen returns YES.
1759 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1760 (check_native_fs): New function.
1761 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1762 (ns_term_init): Remove NEW_STYLE_FS.
1763 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1764 and tool bar if isFullscreen returns NO.
1765 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1766 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1767 with HAVE_NATIVE_FS.
1768 (window:willUseFullScreenPresentationOptions:): New method.
1769 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
1770 Hide toolbar if not enabled (Bug#13444).
1771 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
1772 Restore tool bar if enabled, hide it otherwise (Bug#13444).
1773 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1774 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1775 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1776 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1777 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1778 (syms_of_nsterm): Add ns-use-native-fullscreen.
1780 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1782 * fileio.c (Qchoose_write_coding_system): Now static.
1784 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1786 * xdisp.c (window_buffer_changed): region_showing can be negative,
1787 which still means region is being displayed.
1788 (redisplay_internal): Resurrect code that forced redisplay of the
1789 whole window when showing region and the mark has changed.
1790 Record the new mark position to allow redisplay optimizations.
1791 (display_line): If it->region_beg_charpos is non-zero, set the
1792 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1794 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1795 not bitfield of 1 bit.
1797 2013-02-03 Daniel Colascione <dancol@dancol.org>
1799 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1800 daemon mode works on cygw32 when Emacs is installed and not just
1803 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1805 Avoid file time stamp bug on MS-Windows (Bug#13149).
1806 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1807 as FAT32 doesn't update time stamps when truncating them.
1808 Also, check that a file time stamp is not a multiple of 100 ns;
1809 this should catch all instances of the problem on MS-Windows,
1810 as its native file system resolution is 100 ns or worse, and
1811 checking for a non-multiple of 100 ns should impose only a small
1812 overhead on systems with ns resolution.
1814 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1816 Avoid encoding file names on MS-Windows when they need to be run
1817 through dostounix_filename.
1818 * w32.c (normalize_filename): Accept an additional argument
1819 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1820 downcase it even if w32-downcase-file-names is non-nil.
1821 (dostounix_filename): Accept an additional argument MULTIBYTE and
1822 pass it to normalize_filename.
1823 (emacs_root_dir): Adjust.
1825 * msdos.h (dostounix_filename): Adjust prototype.
1827 * w32.h (dostounix_filename): Adjust prototype.
1829 * msdos.c (dostounix_filename): Accept an additional argument and
1831 (init_environment): Adjust callers of dostounix_filename.
1833 * fileio.c (Ffile_name_directory, file_name_as_directory)
1834 (directory_file_name, Fexpand_file_name)
1835 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1837 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1839 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1840 variables, as egetenv is case-insensitive for DOS_NT.
1842 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1843 with an encoded file name.
1845 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1846 Adjust calls to dostounix_filename.
1848 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1850 * unexw32.c (unexec): Adjust call to dostounix_filename.
1852 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1854 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1857 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1860 * callproc.c (Fcall_process): Make sure program name in PATH and
1861 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1862 is passed to exec/spawnve, which fails unless the file-name
1865 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1866 even if w32-quote-process-args is nil.
1868 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1870 Fix timestamp bug when write-region appends nothing (Bug#13149).
1871 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1872 the file's time stamp doesn't change if Emacs happens to write nothing
1873 to the file, and on a buggy file system this could cause Emacs to
1874 incorrectly infer that the file system doesn't have the bug.
1875 Avoid this problem by inhibiting the inference in this case.

1884 (make_window): Initialize column_number_displayed.
1885 * print.c (print_object): Follow the printed representation of
1886 frames and print window pointer to distinguish between windows.

1893 (display_mode_lines, decode_mode_spec): Adjust users.
1894 * .gdbinit (pwinx): Do not print sequence_number.
1896 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>

1899 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1900 * dired.c: Include <fcntl.h>.
1901 (open_directory): New function, which uses open and fdopendir
1902 rather than opendir. DOS_NT platforms still use opendir, though.

1904 (file_attributes): New function, with most of the old Ffile_attributes.
1905 (directory_files_internal, Ffile_attributes): Use it.
1906 (file_attributes, file_name_completion_stat): First arg is now fd,

1911 (emacs_readlinkat): New function, with much of the old
1912 Ffile_symlink_p, but with an fd argument for speed.
1913 It uses readlinkat rather than careadlinkatcwd, so that it
1914 need not assume the working directory.
1915 (Ffile_symlink_p): Use it.
1916 * filelock.c (current_lock_owner): Use emacs_readlinkat
1917 rather than emacs_readlink.
1918 * lisp.h (emacs_readlinkat): New decl.
1919 (READLINK_BUFSIZE, emacs_readlink): Remove.
1920 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.

1941 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1942 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1945 * w32.c (w32_get_long_filename, init_environment, readlink):
1946 Support file names encoded in DBCS codepages.
1947 (readlink): Use the current file-name-coding-system, not the ANSI
1948 codepage, to decode and handle targets of symlinks.
1950 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1952 * w32.c (opendir): Now accepts a 'const char *'.

1956 Remove obsolete redisplay code. See the discussion at
1957 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1958 * dispnew.c (preemption_period, preemption_next_check): Remove.
1959 (Vredisplay_preemption_period): Likewise.
1960 (update_frame, update_single_window, update_window, update_frame_1):
1961 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1962 used, following the 2012-06-22 change.
1964 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1966 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1968 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1970 * font.c (num_fonts): Remove the leftover from old
1971 debugging code. Adjust comment style here and there.

1976 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1978 * w32.c (max_filename_mbslen): New function.
1979 (normalize_filename, readdir): Use it to detect locales where ANSI
1980 encoding of file names uses a double-byte character set (DBCS).
1981 If a DBCS encoding is used, advance by characters using
1982 CharNextExA, instead of incrementing a 'char *' pointer.
1983 Use _mbslwr instead of _strlwr. (Bug#13515)
1985 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1986 request of memory reservation to 1.7GB. (Bug#13065)
1988 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1990 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1991 at check_extra_latin label. (Bug#13505)
1993 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1995 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1996 Avoid redundant calls to strlen.
1998 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2000 Drop async_visible and async_iconified fields of struct frame.
2001 This is possible because async input is gone; for details, see
2002 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2003 * frame.h (struct frame): Remove async_visible and async_iconified
2004 members, convert garbaged to unsigned bitfield. Adjust comments.
2005 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2006 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2007 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2008 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2009 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2011 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2012 properly. Likewise for obscured.
2014 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2017 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2019 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2021 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2022 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2024 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2026 * xdisp.c (message2, message2_nolog): Remove functions.
2027 (message3, message3_nolog): Extract nbytes and multibyteness directly
2028 from the string. Change all callers.
2029 (message3_nolog): Don't set message_enable_multibyte since set_message
2030 will reset it anyway.
2031 (message1, message1_nolog): Use message3.
2032 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2033 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2034 (set_message): Drop all but the second arg, which has to be a string.
2035 (set_message_1): Simplify now that we know that a1 is NULL and the
2036 second arg is a string.
2037 * frame.h (struct frame): Remove `message_buf' field.
2038 Use glyphs_initialized_p instead.
2039 (FRAME_MESSAGE_BUF): Remove macro.

2044 (read_char_minibuf_menu_width): Remove vars.
2045 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2046 to correctly handle multibyte strings.

2048 * editfns.c (message_text, message_length): Remove vars.
2049 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2050 * fileio.c (auto_save_error): Use message3 instead of message2.
2051 * dispnew.c (adjust_frame_message_buffer): Remove function.
2053 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2055 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2056 real estate used for the tool bar and the menu bar.
2058 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2060 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2061 hidden buffer is prepared to modification (Bug#13164).
2063 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2065 * window.h (struct window): Change window_end_valid member from
2066 Lisp_Object to a bitfield. Adjust comments.
2067 (wset_window_end_valid): Remove.
2068 * window.c (adjust_window_count): Clear window_end_valid.

2073 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2074 * xdisp.c (check_window_end, reconsider_clip_changes)
2075 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2076 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2077 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2079 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2081 * xdisp.c (mark_window_display_accurate): Simplify the loop
2082 assuming that the only one of vchild, hchild or buffer window
2083 slots is non-nil. Call mark_window_display_accurate_1 for
2084 the leaf windows only.
2085 (mark_window_display_accurate_1): Always assume leaf window.
2088 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2090 * emacs.c (Qkill_emacs_hook): Now static.
2092 * fileio.c (Finsert_file_contents): Simplify.
2093 Remove unnecessary assignments and tests.
2095 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2097 * w32.c (acl_set_file): Don't test for errors unless
2098 set_file_security returns FALSE. Avoids spurious errors when
2101 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2103 * fileio.c (Finsert_file_contents): Revert code introduced at
2104 2013-01-18 in favor of the simpler and generally better fix.
2105 Save stack space by removing 'buffer' and reusing 'read_buf'
2108 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2110 * lisp.h (eabs): Define unconditionally (Bug#13419).
2111 The old "#if !defined (eabs)" was an unnecessary revenant of back
2112 when this macro was called "abs". Document 'eabs' better.
2114 2013-01-19 Glenn Morris <rgm@gnu.org>
2116 * fns.c (Frandom): Doc fix.
2118 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2120 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2121 segfault when there are lots of overlays.
2123 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2124 when there are lots of overlays.
2125 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2126 for the details and a way to reproduce.
2128 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2130 * fileio.c: Use O_APPEND to append.
2131 This corresponds better to the natural interpretation of "append",
2132 and avoids the need to open the output file twice, or to invoke
2133 lseek when APPEND is neither nil nor a number.
2134 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2135 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2136 file possibly twice, and lseeking to its end; this avoids the
2137 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2138 at the same time: the combination is never needed and apparently
2139 it doesn't work with DOS_NT.
2141 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2142 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2144 Allow floating-point file offsets.
2145 Problem reported by Vitalie Spinu in
2146 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2147 * fileio.c (emacs_lseek): Remove.
2148 (file_offset): New function.
2149 (Finsert_file_contents, Fwrite_region): Use it.
2151 2013-01-19 Chong Yidong <cyd@gnu.org>
2153 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2154 aborting on Fsignal (Bug#13289).
2156 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2158 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2159 set_file_security as failure due to insufficient privileges.
2160 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2161 (fstat): Return owner and group like 'stat' and 'lstat' do.
2163 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2165 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2166 The bug was observed on Ubuntu operating inside a virtual machine,
2167 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2168 The workaround introduces a race condition on non-buggy hosts,
2169 but it's an unlikely race and anyway there's a nearly identical
2170 nearby race that can't be fixed.
2171 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2173 (Fwrite_region): Test for file system time stamp bug.
2174 (init_fileio): New function.
2175 * lisp.h (init_fileio): Declare it.
2176 * emacs.c (main): Call it.
2178 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2179 and make it more consistent with other stat-failure diagnostics.
2181 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2183 Fix crash when inserting data from non-regular files.
2184 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2185 for the error description produced by valgrind.
2186 * fileio.c (read_non_regular): Rename to read_contents.
2187 Free Lisp_Save_Value object used to pass parameters.
2188 (read_non_regular_quit): Rename to read_contents_quit.
2189 (Finsert_file_contents): Redesign internal file reading loop to adjust
2190 gap and end positions after each read and so help make_gap to work
2191 properly. Do not signal an I/O error too early and so do not leave
2192 not yet decoded characters in a buffer, which was the reason of
2193 redisplay crash. Use list2 to build return value. Adjust comments.
2195 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2197 Close a race when statting and reading files (Bug#13149).
2198 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2199 This avoids a race if the file is renamed between stat and open.
2200 This race is not the problem originally noted in Bug#13149;
2201 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2203 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2210 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2211 * alloc.c (format_save_value): Rename to make_save_value.
2212 (make_save_pointer): New function.
2213 (record_xmalloc): Use make_save_pointer.
2214 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2215 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2216 Change users of make_save_value to make_save_pointer.

2233 (map_keymap_char_table_item): Adjust accordingly.
2234 * fileio.c (non_regular_fd, non_regular_inserted)
2235 (non_regular_nbytes): Remove.
2236 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2237 Use format_save_value to pass parameters to read_non_regular.
2238 (read_non_regular): Use XSAVE_ macros to extract parameters.
2240 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2242 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2244 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2246 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2247 extraction from any Lisp_Save_Value slot. Add type checking.
2248 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2249 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2250 * xselect.c: All users changed.
2252 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>

2263 (save_excursion_restore): Use XSAVE_OBJECT.
2265 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2267 Avoid needless casts with XSAVE_POINTER.
2268 * alloc.c (mark_object) [GC_MARK_STACK]:
2269 * dired.c (directory_files_internal_unwind):
2270 * fileio.c (do_auto_save_unwind):
2271 * gtkutil.c (pop_down_dialog):
2272 * keymap.c (map_keymap_char_table_item):
2273 * lread.c (load_unwind):
2274 * nsmenu.m (pop_down_menu):
2275 * print.c (print_object) [GC_MARK_STACK]:
2276 * xfns.c (clean_up_file_dialog):
2277 * xmenu.c (cleanup_widget_value_tree):
2278 Omit casts between XSAVE_POINTER and a pointer type.
2280 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2282 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
2283 * eval.c (eval_sub): Protect `form' from being GCed before its
2284 car and cdr becomes protected with the backtrace entry.
2286 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2288 Make Lisp_Save_Value more versatile storage for up to four objects.

2290 (struct Lisp_Save_Value): New layout. Adjust comments.
2291 (XSAVE_POINTER): New macro.
2292 (XSAVE_INTEGER): Likewise.

2294 (free_misc): Likewise.
2295 * alloc.c (allocate_misc): Now global.
2296 (free_misc): Likewise. Adjust comment.
2297 (make_save_value): Use new Lisp_Save_Value layout. Adjust comment.
2298 (free_save_value): Likewise.
2299 (mark_object): Likewise.
2300 * editfns.c (save_excursion_save): Pack everything within
2301 Lisp_Save_Value and so avoid xmalloc.
2302 (save_excursion_restore): Adjust to match new layout. Use free_misc
2303 because we do not allocate extra memory any more. Add eassert.
2304 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2305 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
2306 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,

2319 Fix SIGDANGER handlers, for AIX (Bug#13408).
2320 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

2345 (nsfont_list_family): Add block/unblock_input calls.
2346 (nsfont_open): Move block_input earlier. Add unblock_input before early
2348 (nsfont_draw): Add block/unblock_input calls.

2373 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2375 Avoid unnecessary byte position calculation for the gap movement.
2376 Since all users of move_gap do CHAR_TO_BYTE for other purposes
2377 anyway, all of them should use move_gap_both instead.

2387 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
2389 * term.c (init_tty): Use them instead of rolling our own code.
2390 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2391 switches from 'signal' to 'pthread_sigmask', which is safer in
2392 multithreaded applications.
2393 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2394 which has already arranged for that.
2395 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2396 This is the main part of the bug fix.

2408 predicate, which is how it's really used now. Adjust comment.
2409 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2410 * buffer.c (buffer_slot_type_mismatch): Remove.
2411 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
2412 predicate. Adjust comment.

2416 right-fringe-width, scroll-bar-width and buffer-display-count.
2417 Use Qstringp for default-directory, buffer-file-name,
2418 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2419 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
2421 * data.c (store_symval_forwarding): Adjust to call the predicate.
2423 2013-01-09 Juanma Barranquero <lekktu@gmail.com>

2437 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
2438 (make_gap_1): New function to adjust the gap of any buffer.
2439 * coding.c (coding_alloc_by_making_gap): Use it.
2440 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
2441 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

2464 trailing dash is properly added.
2466 2013-01-05 Eli Zaretskii <eliz@gnu.org>
2468 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
2469 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2470 digits for buffer positions, before misalignment starts.
2471 Display "0" for integer "object" field.
2472 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2473 Display the newline glyph more unambiguously.
2475 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2477 * nsterm.m (ns_draw_underwave):
2478 * w32term.c (w32_draw_underwave):
2479 * xterm.c (x_draw_underwave): Make underwave look more triangular
2480 and also degrade gracefully for small fonts. (Bug#13000)
2482 * nsterm.m (ns_draw_text_decoration):
2483 * w32term.c (x_draw_glyph_string):
2484 * xterm.c (x_draw_glyph_string): Don't use previous underline
2485 thickness and position if previous underline type is underwave.
2487 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
2489 * fileio.c (Ffile_acl): Undocument return format.
2491 2013-01-02 Glenn Morris <rgm@gnu.org>
2493 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

2505 * term.c (tty_ins_del_lines):
2506 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2507 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2509 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2511 * w32.c (unsetenv): Set up the string passed to _putenv
2513 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2514 for the bug this caused.
2516 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2518 * coding.c (Qmac): Now static.
2520 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2522 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2523 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

2530 by TOOLBAR_TOP_WIDGET.
2531 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2532 Check toolbar_is_packed.
2533 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on

2535 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2537 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2538 (xg_update_menubar): Update title only if
2539 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2540 (xg_update_submenu): Skip tearoff only if
2541 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2542 (xg_initialize): Initialize xg_detached_menus only if
2543 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2545 * xterm.h (struct x_output): Surround handlebox_widget with
2546 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2547 toolbar_in_hbox is bool.
2549 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2551 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2552 (LIBS_GNUSTEP): Define.
2553 (LIBES): Add $(LIBS_GNUSTEP).

2556 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2558 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2559 continuation glyph on a TTY with an indication of an empty line.
2562 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2564 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2565 file's SELinux context or ACLs successfully set, nil otherwise.
2567 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

2572 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2574 Port EXTERNALLY_VISIBLE to Clang 3.2.
2575 * conf_post.h (__has_attribute): New macro.
2576 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2578 2012-12-27 Glenn Morris <rgm@gnu.org>
2580 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2581 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2583 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2585 * fileio.c (file_name_as_directory, directory_file_name):
2586 Accept an additional argument MULTIBYTE to indicate whether the input C
2587 came from a multibyte or a unibyte Lisp string; all callers
2588 adjusted. Don't assume the input string is always multibyte.
2590 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2591 don't ENCODE_FILE them, and return a unibyte string if the input
2593 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2594 don't assume the input strings will always be multibyte. If the
2595 input strings are multibyte, decode strings obtained from C
2598 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2600 * lisp.h (toplevel): Add two notices to the comment about
2601 defining a new Lisp data type.

2605 * alloc.c (valid_lisp_object_p): Adjust comment.
2607 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2609 * keyboard.c (record_asynch_buffer_change): Initialize an event
2610 only if it's really needed.
2611 * frame.h (enum output_method): Remove output_mac member since
2612 it's a leftover from the deleted code.
2613 * frame.c (Fframep): Adjust user here ...
2614 * terminal.c (Fterminal_live_p): ... and here.
2615 * coding.c (Qmac): Now here because it's only used to denote
2616 end-of-line encoding type.
2617 (syms_of_coding): DEFSYM it.
2618 * frame.h (Qmac): Remove duplicated declaration.
2620 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2622 * window.c (select_window_1): Now static, since it's used only here.
2624 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2626 * window.c (window_body_cols): Subtract display margins from the
2627 window body width on TTYs as well. See
2628 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2629 for the original report.
2631 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2633 * xdisp.c (redisplay_window): Remove inner local variable
2634 because the outer shadowed one has the same meaning.
2635 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2637 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2638 (xg_create_tool_bar): Adjust users.
2640 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2642 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2643 * buffer.c (Fget_buffer_create): Use it to set compact field of
2644 struct buffer_text to avoid accessing an uninitialized value
2645 when compact_buffer is called for the first time.
2646 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2647 (Fset_buffer_modified_p): Use buffer_window_count to check
2648 whether the buffer is displayed in some window.
2649 * xdisp.c (message_dolog): Likewise.
2651 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2653 * w32.c (acl_set_file): If setting the file security descriptor
2654 fails, and the new DACL is identical to the existing one, silently
2655 return success. This fixes problems for users backing up their
2656 own files without having the necessary privileges for setting
2657 security descriptors.
2659 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2661 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2662 after WaitForSingleObject returns normally. This expedites reader
2663 thread shutdown when delete_child triggers it.
2664 (reap_subprocess): More accurate commentary for why we call
2665 delete_child only when cp->fd is negative.
2667 * w32.c (sys_close): Do not call delete_child on a subprocess
2668 whose handle is not yet closed. Instead, set its file descriptor
2669 to a negative value, so that reap_subprocess will call
2670 delete_child on that subprocess when its SIGCHLD arrives.
2671 This avoids closing handles used for communications between sys_select
2672 and reader_thread, which doesn't give sys_select a chance to
2673 notice that the process exited and invoke the SIGCHLD handler for
2676 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2678 * nsfns.m (Fns_do_applescript): Run event loop until script has
2679 been executed (Bug#12969).

2687 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2689 * w32term.c (w32fullscreen_hook): New function.
2690 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2692 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2694 * fileio.c (Finsert_file_contents): Doc fix.
2696 * w32proc.c (new_child, delete_child, find_child_pid): For a
2697 subprocess, consider its slot being in use as long as its process
2698 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2699 slot when a new process is started immediately after killing
2700 another one, without waiting enough time for the first process to
2701 be reaped and resources allocated for it be orderly freed.
2703 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2705 2012-12-21 Chong Yidong <cyd@gnu.org>
2707 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2709 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2711 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2713 * w32.c (get_name_and_id): Always pass NULL as the first argument
2714 of lookup_account_sid. Avoids crashes with UNC file names that
2715 refer to DFS domains, not to specific machine names. (Bug#12621)
2716 Remove now unused argument FNAME; all callers changed.
2717 (get_file_owner_and_group): Remove now unused argument FNAME; all
2720 2012-12-21 Chong Yidong <cyd@gnu.org>
2722 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2723 error for invalid chars, don't check for a nil return value.
2725 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2727 Avoid calls to CHAR_TO_BYTE if byte position is known.
2728 * editfns.c (make_buffer_string_both): Use move_gap_both.
2729 (Fbuffer_string): Use make_buffer_string_both.

2732 (buf_bytepos_to_charpos): Likewise.
2733 (charpos_to_bytepos): Remove.
2734 * fileio.c (Finsert_file_contents): Use move_gap_both.
2735 * search.c (Freplace_match): Likewise.
2736 * process.c (process_send_region): Likewise. Use convenient
2737 names for byte positions.
2738 * lisp.h (charpos_to_bytepos): Remove prototype.
2739 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2740 * insdel.c (move_gap): Likewise.

2748 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2749 (redisplay_internal): Don't bother selecting the frame to get the
2750 proper value of frame-local variables (bug#13225).
2752 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2754 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2755 Rename 4th argument since it may be buffer or string. Adjust comment.
2756 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2758 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2760 * coding.c (Fdetect_coding_region): Do not check start and end with
2761 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2762 (code_convert_region): Likewise.
2764 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2766 * w32.c (acl_get_file, acl_set_file): Run the file name through
2767 map_w32_filename, and resolve any symlinks in the file name, like
2769 (acl_set_file): Call revert_to_self, if any privileges were
2772 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2774 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2775 ($(BLD)/w32.$(O)): Update dependencies.
2777 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2779 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2780 propagate redisplay's scrolling (if any) to the right window.
2781 (redisplay_internal): Use ensure_selected_frame.
2782 (display_mode_lines): Complete last fix.
2783 * window.c (select_window_1): New func, extracted from select_window.
2784 (select_window): Use it.
2785 * window.h (select_window_1): Declare.
2787 2012-12-17 Eli Zaretskii <eliz@gnu.org>

2811 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2813 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2814 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2815 for some of that bug's symptoms can now cause Emacs to abort.
2816 Remove the workaround.
2817 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2818 The bug that caused SIGCHLD to get lost has been fixed, and the
2819 workaround for it can now cause Emacs to abort.
2821 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2823 * sysdep.c (emacs_abort): Bump backtrace size to 40.

2829 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2830 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2831 and copy ACL entries of file in addition to SELinux context if set.
2832 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2834 * Makefile.in (LIBACL_LIBS): New macro.

2849 * w32proc.c (new_child): Initialize input_file and
2850 pending_deletion members of the child.
2851 (delete_child): Delete the child's temporary input file, if any,
2852 that is pending deletion.
2853 (register_child): First argument is now pid_t.
2854 (record_infile, record_pending_deletion): New functions.

2856 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
2858 * fileio.c (internal_delete_file): Return an int again: non-zero

2863 * callproc.c (Fcall_process): Don't overwrite infile with result
2865 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2866 asynchronous subprocess, record the name of the input file name,
2868 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2869 delete the file, record it as pending deletion when the subprocess
2872 2012-12-14 Eli Zaretskii <eliz@gnu.org>

2892 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2894 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2895 try to get accurate owner and group information from NT file
2896 security APIs. This is to make most callers of 'stat' and
2897 'lstat', which don't need that information, much faster.
2899 * dired.c (Ffile_attributes) [WINDOWSNT]:
2900 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2901 owner and group information from 'lstat'.
2903 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2905 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2906 as that confuses set-auto-coding, so insist on the head-read
2907 returning the full 1024 bytes. Let lseek compute the tail offset;
2908 less work for us. Do not ignore I/O errors when reading the tail.

2931 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2932 files, fixing a regression from 24.2.
2933 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2935 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2937 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2938 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2939 Remove unnecessary S_ISLNK test, as (contra the comments) this
2940 function can't copy symlinks. Improve quality of error message
2941 when attempting to copy files that are neither regular files nor

2960 * inotify.c (inotify_callback): Generate an Emacs event for every
2961 incoming inotify event.
2963 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2965 * xdisp.c (handle_face_prop): Fix logic of computing
2966 it->start_of_box_run_p.

2973 left_box_line_p and right_box_line_p flags of the glyph for R2L
2974 glyph rows. (Bug#13011)

3024 (hinst): Remove unneeded extern declaration.
3025 (_start): Remove initialization of above variables; remove

3262 if the child process is still running. Instead, exit the wait
3263 loop and return zero. (Bug#13086)
3265 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3267 * frame.h (x_char_width, x_char_height): Remove prototypes.
3268 * w32term.h (x_char_width, x_char_height): Likewise.
3269 * xfns.c (x_char_width, x_char_height): Remove.
3270 * w32fns.c (x_char_width, x_char_height): Likewise.
3271 * nsfns.c (x_char_width, x_char_height): Likewise.
3272 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
3274 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
3275 * keyboard.c (command_loop_1): Remove prototype.
3276 (command_loop_2, top_level_1): Add static to match prototype.
3278 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
3280 Fix a recently-introduced delete-process race condition.
3281 * callproc.c, process.h (record_kill_process):
3282 New function, containing part of the old call_process_kill.
3283 (call_process_kill): Use it.
3284 This does not change call_process_kill's behavior.
3285 * process.c (Fdelete_process): Use record_kill_process to fix a
3286 race condition that could cause Emacs to lose track of a child.
3288 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3290 Avoid code duplication between prev_frame and next_frame.
3291 * frame.c (candidate_frame): New function. Add comment.
3292 (prev_frame, next_frame): Use it. Adjust comment.
3294 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3296 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3297 fails, signal an error instead of continuing with an empty
3299 Encode expanded temp file pattern before passing it to mkstemp or
3302 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3303 Encode the file name before passing it to dostounix_filename, in
3304 case it will downcase it (under w32-downcase-file-names).
3307 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3309 Minor call-process cleanups.
3310 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3311 at the same time as other platforms, to simplify analysis.
3312 No need for fd0_volatile since we have synch_process_fd.
3313 Avoid needless emacs_close; arg is always negative.
3315 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3317 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3320 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3322 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3323 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3324 and mouse_face_hidden members to a bitfields.
3325 * frame.h (struct frame): Remove set-but-not-used space_width member.
3326 (FRAME_SPACE_WIDTH): Remove.
3327 * nsterm.m, w32term.c, xterm.c: Adjust users.
3328 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3329 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3330 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3331 members to a bitfields.
3333 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3335 Don't let call-process be a zombie factory (Bug#12980).
3336 Fixing this bug required some cleanup of the signal-handling code.
3337 As a side effect, this change also fixes a longstanding rare race
3338 condition whereby Emacs could mistakenly kill unrelated processes,
3339 and it fixes a bug where a second C-g does not kill a recalcitrant
3340 synchronous process in GNU/Linux and similar platforms.
3341 The patch should also fix the last vestiges of Bug#9488,
3342 a bug which has mostly been fixed on the trunk by other changes.
3343 * callproc.c, process.h (synch_process_alive, synch_process_death)
3344 (synch_process_termsig, sync_process_retcode):
3345 Remove. All uses removed, to simplify analysis and so that
3346 less consing is done inside critical sections.
3347 * callproc.c (call_process_exited): Remove. All uses replaced
3348 with !synch_process_pid.
3349 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3350 These take the role of what used to be in unwind-protect arg.
3352 (block_child_signal, unblock_child_signal):
3353 New functions, to avoid races that could kill innocent-victim processes.
3354 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3355 (call_process_kill): Record killed processes as deleted, so that
3356 zombies do not clutter up the system. Do this inside a critical
3357 section, to avoid a race that would allow the clutter.
3358 (call_process_cleanup): Fix code so that the second C-g works again
3359 on common platforms such as GNU/Linux.
3360 (Fcall_process): Create the child process in a critical section,
3361 to fix a race condition. If creating an asynchronous process,
3362 record it as deleted so that zombies do not clutter up the system.
3363 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3364 light of these changes. Omit unnecessary call to emacs_close
3365 before failure, as the unwind-protect code does that.
3366 * callproc.c (call_process_cleanup):
3367 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3368 * process.c (record_deleted_pid): New function, containing
3369 code refactored out of Fdelete_process.
3370 (Fdelete_process): Use it.
3371 (process_status_retrieved): Remove. All callers changed to use
3372 child_status_change.
3373 (record_child_status_change): Remove, folding its contents into ...
3374 (handle_child_signal): ... this signal handler. Now, this
3375 function is purely a handler for SIGCHLD, and is not called after
3376 a synchronous waitpid returns; the synchronous code is moved to
3377 wait_for_termination. There is no need to worry about reaping
3378 more than one child now.
3379 * sysdep.c (get_child_status, child_status_changed): New functions.
3380 (wait_for_termination): Now takes int * status and bool
3381 interruptible arguments, too. Do not record child status change;
3382 that's now the caller's responsibility. All callers changed.
3383 Reimplement in terms of get_child_status.
3384 (wait_for_termination_1, interruptible_wait_for_termination):
3385 Remove. All callers changed to use wait_for_termination.
3386 * syswait.h: Include <stdbool.h>, for bool.
3387 (record_child_status_change, interruptible_wait_for_termination):
3389 (record_deleted_pid, child_status_changed): New decls.
3390 (wait_for_termination): Adjust to API changes noted above.
3392 * bytecode.c, lisp.h (Qbytecode): Remove.
3393 No longer needed after 2012-11-20 interactive-p changes.
3395 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3397 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3398 the scroll margin, move point outside the margin. (Bug#13055)
3400 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3402 * gtkutil.c (my_log_handler): New function.
3403 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3405 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3407 * lisp.h (modify_region): Rename to...
3408 (modify_region_1): ...new prototype.
3409 * textprop.c (modify_region): Now static. Adjust users.
3410 * insdel.c (modify_region): Rename to...
3411 (modify_region_1): ...new function to work with current buffer.
3412 Adjust comment and users. Use true and false for booleans.
3414 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3416 * alloc.c (free_save_value): New function.
3417 (safe_alloca_unwind): Use it.
3418 * lisp.h (free_save_value): New prototype.
3419 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3421 (save_excursion_restore): Adjust to match saved data structure.
3422 Use free_save_value to offload some work from GC. Drop obsolete
3425 2012-12-03 Chong Yidong <cyd@gnu.org>
3427 * fileio.c (Vauto_save_list_file_name): Doc fix.
3429 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3431 * w32fns.c: Remove prototype of atof.
3432 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3434 (file_dialog_callback): Make it UINT_PTR.
3436 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3439 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3440 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3443 2012-12-03 Glenn Morris <rgm@gnu.org>
3445 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3447 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3449 Fix xpalloc confusion after memory is exhausted.
3450 * alloc.c (xpalloc): Comment fix.
3451 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3452 and signals an error, do not clear charset_table_size, as
3453 charset_table is still valid.
3454 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3456 Use execve to avoid need to munge environ (Bug#13054).
3457 * callproc.c (Fcall_process):
3458 * process.c (create_process):
3459 Don't save and restore environ; no longer needed.
3460 * callproc.c (child_setup):
3461 Use execve, not execvp, to preserve environ.
3463 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3465 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3467 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3469 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3470 display for sliced images (Bug#10500).
3472 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3474 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3476 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3477 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3479 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3481 * xdisp.c (window_outdated): Remove eassert since it hits
3482 some suspicious corner cases (see Bug#13007 and Bug#13012).
3483 (mode_line_update_needed): New function.
3484 (redisplay_internal, redisplay_window): Use it.
3485 (ensure_selected_frame): New function.
3486 (redisplay_internal, unwind_redisplay): Use it.
3487 (redisplay_internal): Move comment about buffer_shared...
3488 (buffer_shared_and_changed): ...near to its real use.
3490 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3492 * callproc.c (Fcall_process): Don't misreport vfork failure.
3494 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3496 * callproc.c (Fcall_process): Fix vfork portability problems.
3497 Do not assume that fd[0], count, filefd, and save_environ survive
3498 vfork. Fix bug whereby wrong errno value could be reported for
3499 pipe failure. Some minor cleanups, too, as follows. Move buf and
3500 bufsize to the context where they're needed. Change new_argv to
3501 be of type char **, as this is more convenient and avoids casts.
3502 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3503 Now local constants, not macros.
3505 2012-11-18 Kenichi Handa <handa@gnu.org>
3507 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3508 for the variable "f".
3510 2012-11-13 Kenichi Handa <handa@gnu.org>
3512 * font.c (font_unparse_xlfd): Exclude special characters from the
3513 generating XLFD name.
3515 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>

3519 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
3521 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

3528 * lread.c (readbyte_from_file): Assume EINTR is defined.
3529 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3530 Assume EIO and EAGAIN are defined.
3531 * unexcoff.c (write_segment): Assume EFAULT is defined.
3533 2012-11-27 Eli Zaretskii <eliz@gnu.org>

3540 violations when repeatedly clicking on the "Top" link of the
3541 "bread-crumbs" in Info buffers.

3551 were always defined.
3553 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3555 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3556 between bpos_covered and bpos_max. This fixes cursor display when
3557 several display strings follow each other.
3559 * .gdbinit (pgx): If the glyph's object is a string, display the
3560 pointer to string data, rather than the value of the string object
3561 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3563 * indent.c (Fvertical_motion): If the starting position is covered
3564 by a display string, return to one position before that, to avoid
3565 overshooting it inside move_it_to. (Bug#12930)
3567 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

3578 Drop unused pending_menu_activation member.
3579 * xterm.h (struct x_output): Drop outdated #if 0 code.
3580 Use bitfields for explicit_parent, asked_for_visible,
3581 has_been_visible and net_wm_state_hidden_seen members.

3586 of a literal "/". (Bug#12955)
3587 (gl-stamp): Invoke fc.exe directly, not through cmd.

3592 * dired.c: Assume HAVE_DIRENT_H.
3593 (NAMLEN): Remove, replacing with ...
3594 (dirent_namelen): New function. All uses changed. Use the GNU macro
3595 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3596 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3597 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3598 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3600 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3601 * ndir.h: Rename to ../nt/inc/dirent.h.
3602 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3603 Do not include <dirent.h>; no longer needed.
3604 * w32.c: Include <dirent.h> rather than "ndir.h".
3606 2012-11-23 Chong Yidong <cyd@gnu.org>
3608 * xftfont.c (xftfont_open): Remove duplicate assignment.
3610 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3612 * alloc.c (Fgarbage_collect): Unblock input after clearing
3613 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3614 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3615 * msdos.c (IT_frame_up_to_date): Use it here...
3616 * w32term.c (w32_frame_up_to_date): ...here...
3617 * xterm.c (XTframe_up_to_date): ...and here...
3618 * nsterm.m (ns_frame_up_to_date): ...but not here.
3619 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3621 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3622 Do not check whether GC is in progress.

3626 * xdisp.c (window_buffer_changed): New function.
3627 (update_menu_bar, update_tool_bar): Use it to
3628 simplify large 'if' statements.

3630 'tail' and 'frame' local variables.
3632 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3634 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3635 with Windows system header.
3637 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3639 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).

3656 * emacs.c (main): Set the G_SLICE environment variable for all
3657 Cygwin builds, not just GTK builds. See
3658 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3660 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3662 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3663 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3664 Define for the MSVC compiler.
3666 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3668 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3669 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3670 dostounix_filename. Prevents crashes down the road, because
3671 dostounix_filename assumes it gets a unibyte string.
3672 Reported by Michel de Ruiter <michel@sentient.nl>, see

3719 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3721 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3723 * w32select.c: Include w32common.h before w32term.h, so that
3724 windows.h gets included before w32term.h uses some of its
3725 features, see below.
3727 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3729 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3731 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3733 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3735 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3736 (ns_select): Return at once if events are held (Bug#12834).
3738 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3740 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3741 Needed following 2012-10-20 change. (Bug#12902)
3743 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3745 * w32proc.c (waitpid): Remove unused label get_result.
3747 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3749 * makefile.w32-in (SYSWAIT_H): New macro.
3750 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3751 ($(BLD)/sysdep.$(O)): Update dependencies.
3753 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3755 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3756 * callproc.c (relocate_fd): Assume F_DUPFD.
3757 * emacs.c, term.c (O_RDWR): Remove.
3758 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3759 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3760 * nsterm.m: Assume <fcntl.h> exists.
3761 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3762 (create_pty, Fmake_network_process, server_accept_connection)
3763 (wait_reading_process_output, init_process_emacs):
3765 (wait_reading_process_output): Put in a special case for WINDOWSNT
3766 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3767 It's not clear this is needed, but it's a more-conservative change.
3768 (create_process): Assume FD_CLOEXEC.
3769 (create_process, create_pty): Assume O_NOCTTY.
3770 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3771 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3772 Omit if not DOS_NT, since F_GETFL is not defined there.
3773 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3774 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3776 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3777 lack it, since gnulib guarantees this.
3778 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3780 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3782 * w32.c (faccessat): Pretend that directories have the execute bit
3783 set. Emacs expects that, e.g., in files.el:cd-absolute.
3785 * w32proc.c (create_child): Don't clip the PID of the child
3786 process to fit into an Emacs integer, as this is no longer a
3788 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3789 reaping only the process specified by PID argument, if that is
3790 positive. Use PID instead of dead_child to know which process to
3791 reap. Wait for the child to die only if WNOHANG is not in
3793 (sys_select): Don't set dead_child.
3795 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3796 as it is no longer needed.
3798 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3800 (record_child_status_change): Remove the setting of
3801 record_at_most_one_child for the !WNOHANG case.
3803 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3805 Fix problems in ns port found by static checking.
3806 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3807 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3808 not to process group.
3809 (ns_select): Use emacs_write, not write, as that's more robust
3810 in the presence of signals.
3811 (fd_handler:): Check for read errors.
3813 2012-11-16 Glenn Morris <rgm@gnu.org>
3815 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3817 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3819 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3821 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3823 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3824 use the same value of thread handle.
3825 (start_timer_thread): If the timer thread exited (due to error),
3826 clean up by closing the two handles it used. Duplicate the caller
3827 thread's handle here, so it gets duplicated only once, when
3828 launching the timer thread. Set priority of the timer thread, not
3830 (getitimer): Don't duplicate the caller thread's handle here.
3833 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3835 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3838 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3840 Remove no-longer-used pty_max_bytes variable.
3841 * process.c (pty_max_bytes): Remove; unused.
3842 (send_process): Do not set it.
3844 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3846 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3847 Update dependencies.
3849 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3851 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3852 This follows up on the 2012-09-29 patch that removed indirection
3853 for the 'function' field. Reported by Sergey Vinokurov in
3854 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3856 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3858 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3859 different name, as the MS runtime does not have such a function,
3860 and probably never will.) All callers changed. Ignore DIRFD
3861 value if PATH is an absolute file name, to match Posix spec
3862 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3865 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3867 * xdisp.c (echo_area_display, redisplay_internal):
3868 Omit redundant check whether frame_garbaged is set.
3870 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3872 Use faccessat, not access, when checking file permissions (Bug#12632).
3873 This fixes a bug that has been present in Emacs since its creation.
3874 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3875 which must set some sort of record. (Torek's bug report was against
3876 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3877 same common flaw.) See Torek's Usenet posting
3878 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3879 Posted: Fri Apr 8 14:18:56 1983.
3880 * Makefile.in (LIB_EACCESS): New macro.
3882 * callproc.c (init_callproc):
3883 * charset.c (init_charset):
3884 * fileio.c (check_existing, check_executable, check_writable)
3886 * lread.c (openp, load_path_check):
3887 * process.c (allocate_pty):
3889 Use effective UID when checking permissions, not real UID.
3890 * callproc.c (init_callproc):
3891 * charset.c (init_charset):
3892 * lread.c (load_path_check, init_lread):
3893 Test whether directories are accessible, not merely whether they exist.
3894 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3895 * fileio.c (check_existing, check_executable, check_writable)
3897 Use symbolic names instead of integers for the flags, as they're
3899 (check_writable): New arg AMODE. All uses changed.
3900 Set errno on failure.
3901 (Ffile_readable_p): Use faccessat, not stat + open + close.
3902 (Ffile_writable_p): No need to call check_existing + check_writable.
3903 Just call check_writable and then look at errno. This saves a syscall.
3904 dir should never be nil; replace an unnecessary runtime check
3905 with an eassert. When checking the parent directory of a nonexistent
3906 file, check that the directory is searchable as well as writable, as
3907 we can't create files in unsearchable directories.
3908 (file_directory_p): New function, which uses 'stat' on most platforms
3909 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3910 (Ffile_directory_p, Fset_file_times): Use it.
3911 (file_accessible_directory_p): New function, which uses a single
3912 syscall for efficiency.
3913 (Ffile_accessible_directory_p): Use it.
3914 * xrdb.c (file_p): Use file_directory_p.
3915 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3916 * lread.c (openp): When opening a file, use fstat rather than
3917 stat, as that avoids a permissions race. When not opening a file,
3918 use file_directory_p rather than stat.
3919 (dir_warning): First arg is now a usage string, not a format.
3920 Use errno. All uses changed.
3921 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3922 that merely introduced a race.
3923 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3924 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3925 and similarly for the other O_* flags.
3926 * w32.c (sys_faccessat): Rename from sys_access and switch to
3927 faccessat's API. All uses changed.
3928 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3929 (magic_db): Rename from magic_file_p.
3930 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3931 char *, so that we don't have to test for file existence
3932 separately from opening the file for reading. This removes a race
3933 fixes a permission-checking problem, and simplifies the code.
3935 (file_p): Remove; no longer needed.
3937 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3939 Omit glyphs initialization at startup.
3940 * dispnew.c (glyphs_initialized_initially_p): Remove.
3941 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3942 (Fredraw_frame): Move actual code from here...
3943 (redraw_frame): ...to here. Add eassert. Adjust comment.
3944 (Fredraw_display): Use redraw_frame.
3945 * xdisp.c (clear_garbaged_frames): Likewise.
3947 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3949 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3950 passed to pint2str and pint2hrstr to be at most the size of the
3951 frame's decode_mode_spec_buffer. This avoids crashes with very
3952 large values of FIELD_WIDTH argument to decode_mode_spec.
3955 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3957 Fix a race with verify-visited-file-modtime (Bug#12863).
3958 Since at least 1991 Emacs has ignored an mtime difference of no
3959 more than one second, but my guess is that this was to work around
3960 file system bugs that were fixed long ago. Since the race is
3961 causing problems now, let's remove that code.
3962 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3963 whose time stamp is off by no more than a second. Insist that the
3964 file time stamps match exactly.
3966 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3968 * frame.h (struct frame): Convert external_tool_bar member to
3969 1-bit unsigned bitfield.
3970 * termhooks.h (struct terminal): Remove mouse_moved member since
3971 all users are long dead. Adjust comment on mouse_position_hook.
3973 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3975 Simplify by using FOR_EACH_FRAME here and there.
3976 * frame.c (next_frame, prev_frame, other_visible_frames)
3977 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3978 * w32term.c (x_window_to_scroll_bar): Likewise.
3979 * window.c (window_list): Likewise.
3980 * xdisp.c (x_consider_frame_title): Likewise.
3981 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3982 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3983 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3984 * xmenu.c (menubar_id_to_frame): Likewise.
3985 * xselect.c (frame_for_x_selection): Likewise.
3986 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3987 (x_window_to_menu_bar): Likewise.
3988 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3990 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3992 * data.c (Qdefalias_fset_function): Now static.
3994 Another tweak to vectorlike_header change.
3995 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3996 Remove, and replace all uses with ...
3997 (next_in_free_list, set_next_in_free_list):
3998 New functions, which respect C's aliasing rules better.
4000 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4002 * window.c (list4i): Rename from 'quad'. All uses changed.
4003 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4005 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4007 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4008 warning about mixing declarations and code in ISO C90.
4010 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4012 * window.c (Fsplit_window_internal): Set combination limit of
4013 new parent window to t iff Vwindow_combination_limit is t;
4014 fixing a regression introduced with the change from 2012-09-22.
4015 (Fset_window_combination_limit): Fix doc-string.
4017 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4019 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4020 amount when the scroll margins are too large. When scrolling
4021 backwards in the buffer, give up if cannot reach point or the
4022 scroll margin within a reasonable number of screen lines.
4023 Fixes point position in window under scroll-up/down-aggressively when
4024 point is positioned many lines beyond the window top/bottom.
4027 * ralloc.c (relinquish): If real_morecore fails to return memory
4028 to the system, don't crash; instead, leave the last heap
4029 unchanged and return. (Bug#12774)
4031 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4033 * lisp.h (AUTOLOADP): New macro.
4034 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
4035 * data.c (Ffset): Remove special ad-advice-info handling.
4036 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
4038 (Finteractive_form): Simplify.
4039 (Fquo): Don't insist on having at least 2 arguments.
4040 (Qdefalias_fset_function): New var.
4042 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4044 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4046 * nsfont.m (Qcondensed, Qexpanded): New variables.
4047 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
4048 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4050 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4052 Fix recently introduced crash on MS-Windows (Bug#12839).
4053 * w32term.h (struct scroll_bar): Use convenient header.
4054 (SCROLL_BAR_VEC_SIZE): Remove.
4055 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4057 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4059 Tweak last vectorlike_header change.
4060 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4061 vectorlike object on the free list. This is introduced to avoid
4062 some (but not all) pointer casting and aliasing problems, see
4063 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4064 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
4066 (xvectype, xvecsize): Use them to examine Lisp_Object values.
4068 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4070 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4071 been removed, so remove them here also.
4073 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4075 * doc.c (Fdocumentation): Handle new property
4076 dynamic-docstring-function to replace the old ad-advice-info.
4078 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4080 * fns.c (Qeql, hashtest_eq): Now static.
4082 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4084 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4085 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4086 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
4087 * buffer.c (compare_overlays): Use XLI rather than XHASH.
4089 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
4091 Use same hash function for hashfn_profiler as for hash_string etc.
4092 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4093 * lisp.h (sxhash_combine): New inline function, with the contents
4094 of the old SXHASH_COMBINE.
4095 * profiler.c (hashfn_profiler): Use it, instead of having a
4096 special hash function containing a comparison that always yields 1.
4098 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4100 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4101 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4102 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4105 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4107 * image.c (xpm_make_color_table_h): Fix compiler error because
4108 make_hash_table changed.
4110 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4112 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4114 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4116 Use ad-hoc comparison function for the profiler's hash-tables.
4117 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4118 (make_log): Use them.
4119 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4120 call Fequal any more.
4121 (Ffunction_equal): New function.

4129 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4130 (hash_lookup, hash_remove_from_table): Move assertion checking of
4131 hashfn result here. Check hash-equality before calling cmpfn.
4132 (Fmake_hash_table): Adjust call to make_hash_table.
4133 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
4134 (syms_of_fns): Initialize them.

4141 2012-11-08 Eli Zaretskii <eliz@gnu.org>
4143 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4144 value of w32-scroll-lock-modifier is neither nil nor one of the
4145 known key modifiers. (Bug#12806)
4147 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4149 Shrink struct vectorlike_header to the only size field.
4150 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4152 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4153 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4154 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4155 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4156 information from the vector header. Adjust comment.
4157 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)

4165 (sweep_string, lisp_malloc): Remove useless prototypes.
4166 (enum mem_type): Adjust comment.
4167 (NEXT_IN_FREE_LIST): New macro.
4168 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4169 (Fmake_bool_vector): Likewise.
4170 (struct large_vector): New type to represent allocation unit for
4171 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4172 (large_vectors): Change type to struct large_vector.
4173 (allocate_vector_from_block): Simplify.
4174 (PSEUDOVECTOR_NBYTES): Replace with...
4175 (vector_nbytes): ...new function. Adjust users.
4176 (sweep_vectors): Adjust processing of large vectors.
4177 (allocate_vectorlike): Likewise.
4178 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4179 Add easserts. Adjust XSETPVECTYPESIZE usage.
4180 (allocate_buffer): Use BUFFER_PVEC_INIT.
4181 (live_vector_p): Adjust to match large vector.
4182 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4183 * buffer.h (struct buffer): Add next member.
4184 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4186 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
4187 * fns.c (internal_equal): Adjust to match enum pvec_type change.
4188 (copy_hash_table): Adjust to match vector header change.
4189 * lread.c (defsubr): Use XSETPVECTYPE.
4190 * .gdbinit (xpr, xbacktrace): Adjust to match vector header change.
4191 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
4192 (xvecsize): New command.
4194 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4196 * keyboard.c (event_to_kboard): Do not dereference
4197 frame_or_window field of SELECTION_REQUEST_EVENT
4198 and SELECTION_CLEAR_EVENT events (Bug#12814).
4199 * xterm.h (struct selection_input_event): Adjust comment.
4201 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4203 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4204 such as Scroll Lock, if the respective keys are treated as
4205 function keys, not as modifiers. This avoids destroying non-ASCII
4206 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4208 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4210 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4212 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4214 Restore some duplicate definitions (Bug#12814).
4215 This undoes part of the 2012-11-03 changes. Some people build
4216 with plain -g rather than with -g3, and they need the duplicate
4217 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4218 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4219 Define as macros, as well as as enums or as constants.
4221 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4223 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4224 to keypad keys (Bug#12816).
4226 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4228 Minor adjustments of recently-changed frame functions.
4229 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4230 known to be a frame (we're in the FRAMEP branch).
4231 * lisp.h (Qframep): Remove decl. frame.h declares this.
4232 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4233 since they're meant for Lisp fixnum values.
4235 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4237 * window.c (Fwindow_combination_limit): Revert to the only
4238 required argument and adjust docstring as suggested in
4239 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4240 by Martin Rudalics <rudalics@gmx.at>.
4242 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4244 Widely used frame validity and checking functions.
4245 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4246 * frame.c (decode_live_frame, decode_any_frame): New functions.
4247 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4248 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4249 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
4250 (Fframe_pointer_visible_p): Use decode_any_frame.
4251 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
4252 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
4253 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
4254 (Fframe_focus): Likewise. Allow zero number of arguments.
4256 (frame_buffer_list, frame_buffer_predicate): Remove.
4257 * lisp.h (frame_buffer_predicate): Remove prototype.
4258 * buffer.c (Fother_buffer): Use decode_any_frame.
4259 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4260 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4261 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4262 (Fclose_font, Ffont_info): Use decode_live_frame.
4263 * fontset.c (check_fontset_name): Likewise.
4264 * terminal.c (Fframe_terminal): Likewise.
4265 * w32fns.c (check_x_frame): Likewise.
4266 * window.c (Fminibuffer_window, Fwindow_at)
4267 (Fcurrent_window_configuration): Likewise.
4268 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4269 Likewise. Allow zero number of arguments. Adjust docstring.
4270 * dispnew.c (Fredraw_frame): Likewise.
4271 * xfaces.c (frame_or_selected_frame): Remove.
4272 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4273 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4274 (Fframe_face_alist): Use decode_live_frame.
4275 * xfns.c (check_x_frame): Likewise.
4277 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4279 * window.c (quad): New function.
4280 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4281 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4282 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4283 (Fwindow_line_height): Use it.
4284 (Fwindow_fringes): Use list3.
4285 (Fwindow_scroll_bars): Use list4.
4286 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4287 (Fwindow_combination_limit): Allow zero number of arguments.
4289 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4291 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4293 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4294 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4295 file descriptor 2 for standard error. (Bug#12805)
4297 2012-11-05 Chong Yidong <cyd@gnu.org>
4299 * process.c (wait_reading_process_output): Revert previous change.
4301 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4303 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4304 This removes code that has been obsolete since around 1990.
4305 * callproc.c (Fcall_process):
4307 * process.c (create_process):
4308 * term.c (dissociate_if_controlling_tty):
4309 Assume setsid exists.
4310 * callproc.c (child_setup): Assume setpgid exists and behaves as
4311 per POSIX.1-1988 or later.
4312 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4313 * emacs.c (shut_down_emacs):
4314 * sysdep.c (sys_suspend, init_foreground_group):
4315 Assume getpgrp behaves as per POSIX.1-1998 or later.
4316 * msdos.c (setpgrp): Remove.
4317 (tcgetpgrp, setpgid, setsid): New functions.
4318 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4319 * term.c (no_controlling_tty): Remove; unused.
4320 * w32proc.c (setpgrp): Remove.
4321 (setsid, tcgetpgrp): New functions.
4323 Simplify by assuming __fpending.
4324 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4325 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4326 Do not assume that __fpending's result fits in int.
4328 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4330 Remove EMACS_OUTQSIZE+sleep hack.
4331 * dispnew.c (update_frame_1): Remove hack for terminals slower
4332 than 2400 bps, which throttled Emacs by having it sleep.
4333 This code hasn't worked since at least 2007, when the multi-tty stuff
4334 was added, and anyway those old terminals are long dead.
4335 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4336 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4338 Fix data-loss with --version (Bug#9574).
4339 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4340 as we can't assume that emacs_strerror is initialized, and strerror
4341 is good enough here.
4342 (main): Invoke atexit earlier, to catch earlier instances of
4343 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4345 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4347 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4348 (keyDown): Remap keypad keys to X11 virtual key codes.
4350 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4352 Fix data-loss with --batch (Bug#9574).
4353 * emacs.c: Include <close-stream.h>.
4354 (close_output_streams): New function.
4355 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4356 and handles errors appropriately.
4357 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4360 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4361 The symptom is a diagnostic "GLib-WARNING **: In call to
4362 g_spawn_sync(), exit status of a child process was requested but
4363 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4364 waitpid(), so exit status can't be returned." The diagnostic
4365 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4366 The real bug is a race condition between Emacs and glib: Emacs
4367 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4368 so that glib can't find it. Work around the bug by invoking
4369 waitpid only on subprocesses that Emacs itself creates.
4370 * process.c (create_process, record_child_status_change):
4371 Don't use special value -1 in pid field, as the caller now must
4372 know the pid rather than having the callee infer it.
4373 The inference was sometimes incorrect anyway, due to another race.
4374 (create_process): Set new 'alive' member if child is created.
4375 (process_status_retrieved): New function.
4376 (record_child_status_change): Use it.
4377 Accept negative 1st argument, which means to wait for the
4378 processes that Emacs already knows about. Move special-case code
4379 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4380 processes that have already been waited for, by testing and
4381 clearing new 'alive' member.
4382 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4383 now does this internally.
4384 (handle_child_signal): Let record_child_status_change do all
4385 the work, since we do not want to reap all exited child processes,
4386 only the child processes that Emacs itself created.
4387 * process.h (Lisp_Process): New boolean member 'alive'.
4389 Omit duplicate definitions no longer needed with gcc -g3.
4390 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4391 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4392 Define only as macros. There's no longer any need to also define
4393 these symbols as enums or as constants, since we now assume
4394 gcc -g3 when debugging.
4396 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4398 * lisp.mk: Adjust comments to the fact that term/internal is now
4399 loaded from loadup.el.
4401 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4402 (msdos_fatal_signal): New function.
4403 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4406 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4407 for GCC versions before 4.
4408 (emacs_raise): Define to call msdos_fatal_signal.
4410 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4411 iterator when starting in the middle of a display or overlay
4414 2012-11-03 Chong Yidong <cyd@gnu.org>
4416 * process.c (wait_reading_process_output): Clean up the last
4419 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4421 * process.c (wait_reading_process_output): Avoid a race condition
4422 with SIGIO delivery (Bug#11536).
4424 2012-11-03 Chong Yidong <cyd@gnu.org>
4426 * buffer.c (cursor_type): Untabify docstring.
4428 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4430 * frame.h (struct frame): Drop can_have_scroll_bars member
4431 which is meaningless for a long time. Adjust comments.
4432 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4433 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4435 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4437 * window.c (decode_next_window_args): Update window arg after
4438 calling decode_live_window and so fix crash reported at
4439 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4440 by Juanma Barranquero <lekktu@gmail.com>.
4441 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4442 * font.c (Ffont_at): Likewise.
4444 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4446 * widget.c (resize_cb): New function.
4447 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4448 (EmacsFrameResize): Check if all is up to date before changing frame
4451 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4453 Implement backtrace output for fatal errors on MS-Windows.
4454 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4455 (BACKTRACE_LIMIT_MAX): New macro.
4456 (w32_backtrace): New function.
4457 (emacs_abort): Use w32_backtrace when the user chooses not to
4458 attach a debugger. Update the text of the abort dialog.
4460 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4462 Window-related stuff cleanup here and there.
4463 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4464 Use decode_any_window.
4465 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4466 * xdisp.c (Fformat_mode_line): Likewise.
4467 * font.c (Ffont_at): Use decode_live_window.
4468 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4469 * window.c (decode_next_window_args): Likewise.
4470 (decode_any_window): Remove static.
4471 * window.h (decode_any_window): Add prototype.
4472 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4473 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4476 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4478 Remove pad from struct input_event.
4479 * termhooks.h (struct input_event): Remove padding field.
4481 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4482 member is never cons for a long time. Adjust comment.
4483 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4484 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4485 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4486 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4488 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4490 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4492 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4494 Fix crash when using Emacs as commit editor for git (Bug#12697).
4495 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4496 and it is configured in conf_post.h.
4497 (Fcall_process): Don't invoke both setsid and setpgid; the former
4498 is enough, if it exists.
4499 * callproc.c (Fcall_process, child_setup):
4500 * process.c (create_process): Use setpgid.
4501 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4503 * dispnew.c (init_display): Initialize the foreground group
4504 if we are running a tty display.
4505 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4506 * lisp.h (init_foreground_group): New decl.
4507 * sysdep.c (inherited_pgroup): New static var.
4508 (init_foreground_group, tcsetpgrp_without_stopping)
4509 (narrow_foreground_group, widen_foreground_group): New functions.
4510 (init_sys_modes): Narrow foreground group.
4511 (reset_sys_modes): Widen foreground group.
4513 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4515 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4517 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4519 * minibuf.c (read_minibuf): Restore current buffer since
4520 choose_minibuf_frame calling Fset_frame_selected_window may
4521 change it (Bug#12766).
4523 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4525 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4527 2012-10-30 Kenichi Handa <handa@gnu.org>
4529 * font.c (Ffont_at): If WINDOW is specified and it is not
4530 displaying the current buffer, signal an error.
4532 2012-10-29 Daniel Colascione <dancol@dancol.org>
4534 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4535 In preparation for fixing bug#12739, move these functions from
4538 * coding.h, coding.c: ... to here, and compile them only when
4539 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4540 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4542 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4544 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4545 (timer_loop, getitimer, setitimer): Use it instead of
4546 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4548 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4551 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4553 * nsterm.m (NO_APPDEFINED_DATA): New define.
4554 (last_appdefined_event_data): New variable
4555 (last_appdefined_event): Remove.
4556 (ns_select): Initialize t from last_appdefined_event_data instead
4557 of [last_appdefined_event data1].
4558 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4559 remove last_appdefined_event (Bug#12698).
4561 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4563 * frame.c (x_set_font): Catch internal error.
4565 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4567 Avoid overflow in w32 implementation of interval timers.
4568 When possible, for ITIMER_PROF count only times the main thread
4570 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4571 'volatile ULONGLONG' types. All the other data which was
4572 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4573 (GetThreadTimes_Proc): New typedef.
4574 (w32_get_timer_time): New function, returns a suitable time value
4576 (timer_loop): Enter critical section when accessing ULONGLONG
4577 values of the itimer_data struct, as these accesses are no longer
4578 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4579 Remove unused variable.
4580 (init_timers): Initialize s_pfn_Get_Thread_Times.
4581 (start_timer_thread): Don't assign itimer->caller_thread here.
4582 (getitimer): Assign itimer->caller_thread here.
4583 (setitimer): Always call getitimer to get the value of ticks_now.
4584 (sys_spawnve): Avoid compiler warning about format mismatch.
4586 2012-10-26 Eli Zaretskii <eliz@gnu.org>
4588 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4589 mouse movement events if the menu bar is active. This avoids
4590 producing a busy "hour-glass" cursor by Windows if the mouse
4591 pointer is positioned over a tooltip shown for some menu item.
4593 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4595 Don't assume process IDs fit in int.
4596 * emacs.c (shut_down_emacs) [!DOS_NT]:
4597 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4598 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4599 Use pid_t, not int, to store process IDs, as 'int'
4600 is not wide enough on a few platforms (e.g., AIX and IRIX).
4602 2012-10-23 Kenichi Handa <handa@gnu.org>
4604 The following change is to make face-font-rescale-alist work

5086 * cygw32.h: Remove obsolete EXFUN declarations.
5088 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5090 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5091 of w32inevt.o from SOME_MACHINE_OBJECTS.
5093 2012-10-08 Daniel Colascione <dancol@dancol.org>
5095 * image.c: Permanent fix for JPEG compilation issue --- limit
5096 jpeglib `boolean' redefinition to Cygwin builds.
5098 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5100 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5102 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5105 2012-10-08 Daniel Colascione <dancol@dancol.org>
5107 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5108 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5109 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5110 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5111 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5112 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5113 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5114 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5115 now a supported configuration.
5117 * Makefile.in: consolidate image variables into LIBIMAGE; add
5118 W32_OBJ and W32_LIBS. Compile new files.
5121 (_DebPrint) declare tracing facility for W32 debugging. We need
5122 to unify tracing later.
5124 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5125 unconditional use of W32 Unicode functions. Cygwin runs only on
5126 100% Unicode operating systems.
5128 * cygw32.c: New file. Define Cygwin-specific facilities.
5129 (Fcygwin_convert_path_to_windows)
5130 (Fcygwin_convert_path_from_windows): New user functions for
5131 accessing Cygwin path-munging routines.
5133 * cygw32.h: New file.
5134 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5135 UTF-16LE strings temporarily inside non-Lisp-visible string
5138 (w32_strerror): Just what it says on the tin.
5140 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5141 also run for Cygwin; both systems have the same problem with using
5142 GUI facilities in a forked child. Also call syms_of_cygw32,
5143 syms_of_w32select in correct places.
5145 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5146 needs fork-then-exec for daemon launching.
5148 * font.h: Include frame.h.
5150 * image.c: Use the image library cache machinery only when we're
5151 compiling for native WINDOWSNT; Cygwin can use shared libraries
5152 like any other Unixlike system.
5154 * keyboard.c: Clarify a comment regarding the input loop.
5156 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5157 functions directly instead of trying to detect at runtime that our
5158 host operating system supports them. We make this change for two
5159 reasons: Cygwin lacks support for the multibyte character
5160 conversion functions used by the legacy menu code, and Cygwin
5161 never needs to rely on non-Unicode APIs.
5163 * unexw32.c (hinst): Declare extern.
5165 * w32.c: Change header order;
5166 (w32_strerror): Move to w32fns.c because we need it for
5167 non-WINDOWSNT builds.
5169 * w32.h: Add #error macro to make sure we don't include w32.h for
5170 Cygwin builds. Remove w32select declarations.
5172 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5173 w32fns.c. w32console.c is WINDOWSNT-only.
5175 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5176 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5178 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5179 (w32_major_version, w32_minor_version, w32_build_number)
5180 (os_subtype, sound_type): Define here
5181 (w32_defined_color): Make color parameter const for consistency
5182 with other _defined_color functions.
5183 (w32_createwindow): Unconditionally call w32_init_class instead of
5184 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5185 through the code is complex and unnecessary because class
5186 registration is practically free.
5187 (w32_name_of_message): New EMACSDEBUG-only function.
5188 (Fset_message_beep): Move here
5189 (Fx_open_connection): Require that the display name for Windows be
5190 "w32" for consistency, emacsclient disambiguation, and maybe, one
5191 day, multi-window-system support.
5192 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5193 Cygwin files for W32 GUI facilities, since these clearly don't
5194 expect Cygwin names.
5195 (_DebPrint): Define.
5196 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5197 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5198 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5199 (w32_last_error): Remove.
5201 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5203 * w32heap.c (syspage_mask): Declare here.
5204 (cache_system_info): Remove.
5206 * w32inevt.c (faked_key): Define globally, not statically.
5207 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5208 (w32_console_toggle_lock_key): Move to w32fns.c.
5210 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5212 * w32proc.c (_DebPrint): Move to w32fns.c.
5213 * w32select.c: Include string.h, stdio.h for Cygwin.
5214 * w32select.h: New File.
5216 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5218 (w32_message_fd): New variable. Under Cygwin, holds the file
5219 descriptor the system used to tell us about pending thread
5222 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5223 that prevented compilation under non-WINDOWSNT systems.
5225 (w32_initialize): Open /dev/windows and assign it to
5226 w32_message_fd. Provide w32 feature.
5228 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5229 (WM_EMACS_INPUT_READY): add.
5230 (prepend_msg, w32_message_fd): Declare globally.
5233 (keyboard_handle): Use only when WINDOWSNT.
5234 (notify_msg_ready): New function. Posts a message to the main
5235 thread's message queue under CYGWIN, which wakes up the main
5236 thread from select(2) by making the /dev/windows file descriptor
5237 ready. Under WINDOWSNT, it sets an event the same way the old
5240 (post, prepend_msg): Actually call notify_msg_ready instead of
5241 setting the input event directly.
5243 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5245 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5246 but it still has blocs in it, don't return it to the system,
5247 instead of aborting. (Bug#12402)
5249 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5251 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5253 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5254 MAC_OS_X_VERSION_10_6.
5255 (syms_of_nsterm): Remove comment about Panther and above for
5257 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5258 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5259 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5261 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5262 MAC_OS_X_VERSION_10_4.
5264 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5265 MAC_OS_X_VERSION_10_2.
5267 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5269 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5270 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5272 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5273 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5274 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5275 Remove ns_in_resize check.
5276 (ns_clear_frame_area): Remove resize handle code.
5278 * nsfns.m (ns_in_resize): Remove.
5279 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5280 Remove ns_in_resize check.
5282 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5284 Improve sys_siglist detection.
5285 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5286 defined as a macro, as is done in Solaris.
5287 (sys_siglist_entries): New macro.
5288 (save_strsignal): Use it.
5289 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5290 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5292 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5294 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5295 fullscreen/Fullscreen.
5297 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5298 tobar_height is new.
5300 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5301 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5302 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5303 (windowDidResize:): Check for correct window if old style fullscreen.
5304 Capitalize word in comment. Remove incorrect comment.
5305 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5306 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5307 error in drawing background.
5308 (toggleFullScreen:): Remove comment. Rearrange calls.
5309 Set toolbar values to zero, save old height in tobar_height.
5310 Restore tool bar height when leaving fullscreen.
5311 (canBecomeMainWindow): New function.
5313 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5315 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5317 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5319 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5321 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5322 that time stamps of directories could also be changed.
5323 Don't request the too broad GENERIC_WRITE, only the more restrictive
5324 FILE_WRITE_ATTRIBUTES access rights.
5326 * fileio.c (Fset_file_times): Special-case ignoring errors for
5327 directories only on MSDOS, not on MS-Windows.
5329 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5331 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5333 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5335 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5336 see whether CreateFile failed.
5338 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5340 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5341 to avoid similar races.
5342 * keyboard.c (pending_signals): Now bool, not int.
5344 Port timers to OpenBSD, plus check for timer failures.
5345 OpenBSD problem reported by Han Boetes.
5346 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5348 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5349 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5350 like OpenBSD, which has timer_settime but does not declare it.
5351 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5352 whether to use itimerspec-related primitives. All uses of
5353 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5355 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5357 * profiler.c (handle_profiler_signal): Fix a malloc race
5358 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5360 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5362 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5364 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5366 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5367 consistent with the change in return value of 'safe_strsignal'.
5369 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5371 Prefer plain 'static' to 'static inline' (Bug#12541).
5372 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5373 (bidi_set_sor_type, bidi_push_embedding_level)
5374 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5375 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5376 (bidi_cache_search, bidi_cache_ensure_space)
5377 (bidi_cache_iterator_state, bidi_cache_find)
5378 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5379 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5380 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5381 Now 'static', not 'static inline'.
5383 Count overruns when profiling; change units to ns.
5384 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5385 Give extra weight to samples after overruns, to attempt to count
5386 the time more accurately.
5387 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5388 the underlying primitives nominally do ns.
5389 (Fprofiler_cpu_start): Document the change. Mention that
5390 the sampling intervals are only approximate.
5392 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5394 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5396 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5397 case for the special 0 coding-system.
5399 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5400 (Fmake_overlay): Remove redundant tests.
5401 (fix_start_end_in_overlays): Remove redundant recentering.
5403 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5405 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5406 Update dependencies.
5408 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5410 Fix a malloc race condition involving strsignal.
5411 A signal can arrive in the middle of a malloc, and Emacs's signal
5412 handler can invoke strsignal, which can invoke malloc, which is
5413 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5414 Fix it by altering the signal handler so that it does not invoke
5416 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5417 * process.c (status_message): Use const pointer, in case strsignal
5418 is #defined to safe_strsignal.
5419 * sysdep.c (sys_siglist, init_signals): Always define and
5420 initialize a substitute sys_siglist if the system does not define
5421 one, even if HAVE_STRSIGNAL.
5422 (safe_strsignal): Rename from strsignal. Always define,
5423 using sys_siglist. Return a const pointer.
5424 * syssignal.h (safe_strsignal): New decl.
5425 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5427 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5429 * w32proc.c (timer_loop): Fix code that waits for timer
5430 expiration, to avoid high CPU usage.
5432 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5434 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5435 (sweep_weak_table): Remove redundant prototypes.
5437 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5439 * emacs.c: Move the inclusion of TERM_HEADER after including
5440 windows.h on WINDOWSNT. This avoids compilation problems with
5443 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5445 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5446 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5447 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5448 as the previous version used 'void *'.
5450 * ralloc.c (ROUNDUP): Fix last change.
5451 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5454 * w32proc.c <disable_itimers>: New static flag.
5455 (init_timers): Initialize it to zero, after creating the critical
5456 sections used by the timer threads.
5457 (term_timers): Set to 1 before deleting the critical sections.
5458 (getitimer, setitimer): If disable_itimers is non-zero, return an
5459 error indication without doing anything. Reported by Fabrice
5460 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5461 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5463 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5466 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5467 term_ntproc after all the other bookkeeping, to get timers working
5468 as long as possible.
5470 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5472 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5473 Suggested by Juri Linkov in
5474 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5476 Prefer plain 'static' to 'static inline' (Bug#12541).
5477 With static functions, modern compilers inline pretty well by
5478 themselves; advice from programmers often hurts as much as it helps.
5479 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5480 this change shrinks the text size of the Emacs executable by 1.1%
5481 without affecting CPU significantly in my benchmark.

5566 not enough time to get that tested before the freeze today.
5567 * dired.c (directory_files_internal, Ffile_attributes):
5570 * frame.c (x_report_frame_params): Port better to wider ints.
5571 Do not assume that EMACS_UINT is the same width as uprintmax_t,

5780 for consistency with other handlers.
5781 (setup_cpu_timer): New function, with much of what used to be in

5783 Prefer timer_settime if available, and prefer
5784 thread cputime clocks, then process cputime clocks, then
5785 monotonic clocks, to the old realtime clock. Use make_timeval
5786 to round more-correctly when falling back to setitimer.
5787 (Fprofiler_cpu_start): Use it.
5788 (Fprofiler_cpu_stop): Prefer timer_settime if available.

5855 Since this stuff is now private to charset.c, there's no need for
5856 a public macro and no need to inline by hand.

5994 (x_alloc_lighter_color):
5995 * indent.c (disptab_matches_widthtab, current_column)
5996 (scan_for_column, string_display_width, indented_beyond_p)
5997 (compute_motion, vmotion, Fvertical_motion):
5998 Use bool for booleans.
6000 2012-09-24 Chong Yidong <cyd@gnu.org>
6002 * chartab.c (Fset_char_table_default): Obsolete function removed.
6004 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6006 Move pid_t related decls out of lisp.h.
6007 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6008 (interruptible_wait_for_termination):
6009 Move these decls from lisp.h to syswait.h, since they use pid_t.
6010 Needed on FreeBSD; see Herbert J. Skuhra in
6011 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6012 * callproc.c: Include syswait.h.
6014 gnutls.c, gtkutil.c: Use bool for boolean.
6015 * gnutls.c (gnutls_global_initialized, init_gnutls_functions)
6016 (emacs_gnutls_handle_error):
6017 * gtkutil.c (xg_check_special_colors, xg_prepare_tooltip)

6030 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
6031 * xfns.c (Fx_show_tip) [USE_GTK]:
6032 Use bool for boolean.
6033 * gtkutil.c (xg_update_frame_menubar):
6034 * xmenu.c (update_frame_menubar):
6035 Return void, not int, since caller ignores return value.

6039 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6041 * makefile.w32-in (BLOCKINPUT_H): Remove.

6058 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6060 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6061 fatal_error_backtrace.
6063 * w32proc.c (sys_kill): Undo last change: don't do anything when
6064 invoked to deliver SIGABRT to our own process. This is now
6065 handled by emacs_raise.
6067 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6069 * w32term.c (w32_read_socket): Remove leftover reference to
6070 interrupt_input_pending.
6072 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6074 Do not use SA_NODEFER.
6075 Problem reported by Dani Moncayo in
6076 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6078 * sysdep.c (emacs_abort): Do not reset signal handler.
6079 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6080 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6081 wanted even on POSIXish hosts, and it doesn't work on Windows.
6083 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6085 * xterm.c (x_term_init): Call fixup_locale before and after calling
6086 gtk_init (Bug#12392).
6088 2012-09-23 Chong Yidong <cyd@gnu.org>
6090 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6091 Vdynamic_library_alist.
6093 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6094 (Fgnutls_available_p): Caller changed.
6096 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6097 (Flibxml_parse_xml_region): Likewise.
6099 * dispextern.h (struct image_type): Remove arg from init function.
6101 * image.c (Finit_image_library, lookup_image_type)
6102 (define_image_type): Remove now-unneeded second arg.
6103 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6104 (init_tiff_functions, init_gif_functions, init_svg_functions):
6105 Arglist and w32_delayed_load calling convention changed.
6106 (gs_type): Remove init_gs_functions; there is no such function.
6107 (valid_image_p, make_image): Fix caller to lookup_image_type.
6109 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6111 Simplify and avoid signal-handling races (Bug#12471).
6113 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6114 Avoid recursive loop if there's a fatal error in the function itself.
6115 * atimer.c (pending_atimers):
6116 * blockinput.h: Don't include "atimer.h"; no longer needed.
6117 (interrupt_input_pending): Remove. All uses removed.
6118 pending_signals now counts both atimers and ordinary interrupts.
6119 This is less racy than having three separate pending-signal flags.
6120 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6122 Rename from their upper-case counterparts BLOCK_INPUT,
6123 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6124 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6125 This makes it easier to access volatile variables more accurately.
6126 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6127 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6128 that's more reliable if the code is buggy and sets
6129 interrupt_input_blocked to a negative value. All uses changed.
6130 * atimer.c (deliver_alarm_signal):
6131 Remove. No need to deliver this to the parent; any thread can
6132 handle this signal now. All uses replaced by underlying handler.
6133 * atimer.c (turn_on_atimers):
6134 * dispnew.c (handle_window_change_signal):
6135 * emacs.c (handle_danger_signal):
6136 * keyboard.c (kbd_buffer_get_event):
6137 Don't reestablish signal handler; not needed with sigaction.
6138 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6140 Rework to avoid unnecessary accesses to volatile variables.
6141 (UNBLOCK_INPUT_TO): Now a function.
6142 (totally_unblock_input, unblock_input): New decls.
6143 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6144 (init_data): Remove. Necessary stuff now done in init_signal.
6145 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6146 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6147 (fatal_error_code): Remove; no longer needed.
6148 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6149 it doesn't always backtrace. All uses changed. No need to reset
6150 signal to default, since sigaction and/or die does that for us now.
6151 Use emacs_raise (FOO), not kill (getpid (), FOO).
6152 (main): Check more-accurately whether we're dumping.
6153 Move fatal-error setup to sysdep.c
6154 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6155 * gtkutil.c (xg_get_file_name, xg_get_font):
6156 Remove no-longer-needed signal-mask manipulation.
6157 * keyboard.c, process.c (POLL_FOR_INPUT):
6158 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6159 * keyboard.c (read_avail_input): Remove.
6160 All uses replaced by gobble_input.
6161 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6162 (kbd_buffer_store_event_hold, gobble_input):
6163 (record_asynch_buffer_change) [USABLE_SIGIO]:
6164 (store_user_signal_events):
6165 No need to mess with signal mask.
6166 (gobble_input): If blocking input and there are terminals, simply
6167 set pending_signals to 1 and return. All hooks changed to not
6168 worry about whether input is blocked.
6169 (process_pending_signals): Clear pending_signals before processing
6170 them, in case a signal comes in while we're processing.
6171 By convention callers now test pending_signals before calling us.
6172 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6173 New functions, to support changes to blockinput.h.
6174 (handle_input_available_signal): Now extern.
6175 (reinvoke_input_signal): Remove. All uses replaced by
6177 (quit_count): Now volatile, since a signal handler uses it.
6178 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6179 All callers changed. Block SIGINT only if not already blocked.
6180 Clear sigmask reliably, even if Fsignal returns, which it can.
6181 Omit unnecessary accesses to volatile var.
6182 (quit_throw_to_read_char): No need to restore sigmask.
6183 * keyboard.c (gobble_input, handle_user_signal):
6184 * process.c (wait_reading_process_output):
6185 Call signal-handling code rather than killing ourselves.
6186 * lisp.h: Include <float.h>, for...
6187 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6188 (pending_signals): Now volatile.
6189 (syms_of_data): Now const if IEEE floating point.
6190 (handle_input_available_signal) [USABLE_SIGIO]:
6191 (terminate_due_to_signal, record_child_status_change): New decls.
6192 * process.c (create_process): Avoid disaster if memory is exhausted
6193 while we're processing a vfork, by tightening the critical section
6195 (send_process_frame, process_sent_to, handle_pipe_signal)
6196 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6198 (send_process): No need for setjmp/longjmp any more, since the
6199 SIGPIPE stuff is now gone. Instead, report an error if errno
6201 (record_child_status_change): Now extern. PID and W are now args.
6202 Return void, not bool. All callers changed.
6203 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6204 Remove. All uses removed. This bug should be fixed now in a
6206 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6207 and record the child status change directly. This avoids the
6208 need to futz with the signal mask.
6209 (process_fatal_action): Move here from emacs.c.
6210 (emacs_sigaction_flags): New function, containing
6211 much of what used to be in emacs_sigaction_init.
6212 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6213 caught by emacs, to make races less likely.
6214 (deliver_process_signal): Rename from handle_on_main_thread.
6216 (BACKTRACE_LIMIT_MAX): Now at top level.
6217 (thread_backtrace_buffer, threadback_backtrace_pointers):
6219 (deliver_thread_signal, deliver_fatal_thread_signal):
6220 New functions, for more-accurate delivery of thread-specific signals.
6221 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6222 (deliver_arith_signal): Handle in this thread, not
6223 in the main thread, since it's triggered by this thread.
6224 (maybe_fatal_sig): New function.
6225 (init_signals): New arg DUMPING so that we can be more accurate
6226 about whether we're dumping. Caller changed.
6227 Treat thread-specific signals differently from process-general signals.
6228 Block all signals while handling fatal error; that's safer.
6229 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6231 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6232 Ignore SIGPIPE unless batch.
6233 (emacs_backtrace): Output backtrace for the appropriate thread,
6234 which is not necessarily the main thread.
6235 * syssignal.h: Include <stdbool.h>.
6236 (emacs_raise): New macro.
6237 * xterm.c (x_connection_signal): Remove; no longer needed
6238 now that we use sigaction.
6239 (x_connection_closed): No need to mess with sigmask now.
6240 (x_initialize): No need to reset SIGPIPE handler here, since
6241 init_signals does this for us now.
6243 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6245 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6246 background rect may be larger (Bug#12245).
6248 2012-09-23 Chong Yidong <cyd@gnu.org>
6250 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6252 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6254 * .gdbinit: Just stop at fatal_error_backtrace.
6255 See Stefan Monnier's request in
6256 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6257 Remove no-longer-used query of system type.
6259 2012-09-22 Chong Yidong <cyd@gnu.org>
6261 * search.c (Freplace_match): Doc fix (Bug#12325).
6263 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6265 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6266 (Fline_end_position): Doc fix.
6268 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6270 2012-09-22 Chong Yidong <cyd@gnu.org>
6272 * dispextern.h (struct image_type): Add new slot, storing a type
6273 initialization function.
6275 * image.c (define_image_type): Call the image initializer function
6276 if it is defined. Arguments and return value changed.
6277 (valid_image_p, make_image): Callers changed.
6278 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6279 (gif_type, imagemagick_type, svg_type, gs_type):
6280 Add initialization functions.
6281 (Finit_image_library): Call lookup_image_type.
6282 (CHECK_LIB_AVAILABLE): Macro deleted.
6283 (lookup_image_type): Call define_image_type here, rather than via
6284 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6285 (syms_of_image): Move define_image_type calls for xbm_type and
6286 pbm_type to lookup_image_type.
6288 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6290 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6291 'idle_timers' from here ...
6292 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6293 lists, to avoid infloops when the timer does something stupid,
6294 like reinvoke itself with the same or smaller time-out.
6297 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6299 * window.c (Fsplit_window_internal): Handle only Qt value of
6300 Vwindow_combination_limit separately.
6301 (Qtemp_buffer_resize): New symbol.
6302 (Vwindow_combination_limit): New default value.
6305 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6307 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6308 the new overlay string. (Bug#10159)
6310 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6312 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6313 or that fprintf is async-signal-safe. POSIX doesn't require
6316 2012-09-22 Chong Yidong <cyd@gnu.org>
6318 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6321 2012-09-22 Kenichi Handa <handa@gnu.org>
6323 * composite.c (composition_reseat_it): Handle the case that a
6324 grapheme cluster is not covered by a single font (Bug#12352).
6326 2012-09-21 Chong Yidong <cyd@gnu.org>
6328 * image.c (define_image_type): Avoid adding duplicate types to
6329 image_types (Bug#12463). Suggested by Jörg Walter.
6331 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6333 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6334 (print_load_command_name): Add case LC_DATA_IN_CODE.
6335 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6337 2012-09-21 Glenn Morris <rgm@gnu.org>
6339 * eval.c (Frun_hook_with_args_until_success)
6340 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6342 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6344 * fileio.c (Ffile_selinux_context): Only call freecon when
6345 lgetfilecon succeeded.
6346 (Fset_file_selinux_context): Likewise. (Bug#12444)
6348 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6350 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6351 reordering, locate the cursor by calling set_cursor_from_row; if
6352 that fails, clear the desired glyph matrix before returning a
6353 failure indication to the caller. Fixes leaving garbled display
6354 when fast scrolling with a down-key. (Bug#12403)
6355 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6356 scrolling through multibyte text.
6358 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6360 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6361 calling mark_vectorlike since that's the one that marks the window.
6362 (mark_discard_killed_buffers): Mark the final cdr.
6363 * window.h (struct window): Move prev/next_buffers to the
6364 non-standard fields.
6365 * window.c (make_window): Initialize prev/next_buffers manually.
6367 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6369 Omit unused arg EXPECTED from socket hooks.
6370 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6371 * nsterm.m (ns_term_init):
6372 * termhooks.h (struct terminal.read_socket_hook):
6373 * w32inevt.c (w32_console_read_socket):
6374 * w32term.c (w32_read_socket):
6375 * xterm.c (XTread_socket):
6376 Omit unused arg EXPECTED. All callers changed.
6377 (store_user_signal_events): Return void, not int, since callers no
6378 longer care about the return value. All uses changed.
6380 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6382 * w32gui.h (XParseGeometry): Do not declare.
6384 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6386 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6387 Ignore 'expected'. See Eli Zaretskii in
6388 <http://bugs.gnu.org/12471#8> (last line).
6390 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6391 (XParseGeometry): Now static. Substitute extremal values for
6392 values that are out of range.
6394 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6396 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6398 * nsfns.m (XParseGeometry): Remove.
6399 (Fx_create_frame): Call x_set_offset to correctly interpret
6400 top_pos in geometry.
6402 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6403 (Fx_parse_geometry): If there is a space in string, call
6404 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6406 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6408 * search.c (scan_buffer): Use character positions in calls to
6409 region_cache_forward and region_cache_backward, not byte
6410 positions. (Bug#12196)
6412 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6413 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6415 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6416 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6417 emacs_blocked_malloc, now deleted.
6419 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6421 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6422 The workaround was for improving performance on Solaris 2.4, but
6423 is getting in the way now. Emacs will still work if someone is
6424 still running Solaris 2.4 in a museum somewhere; Sun dropped
6425 support for Solaris 2.4 in 2003.
6426 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6427 * process.c (create_process) [HAVE_WORKING_VFORK]:
6428 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6429 since Emacs no longer uses vfork on that platform.
6431 2012-09-17 Glenn Morris <rgm@gnu.org>
6433 * emacs.c: Use COPYRIGHT.
6435 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6437 Remove configure's --without-sync-input option (Bug#12450).
6438 When auditing signal-handling in preparation for cleaning it up,
6439 I found that SYNC_INPUT has race conditions and would be a real
6440 pain to fix. Since it's an undocumented and deprecated
6441 configure-time option, now seems like a good time to remove it.
6442 Also see <http://bugs.gnu.org/11080#16>.
6443 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6444 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6445 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6446 (malloc_hysteresis):
6447 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6448 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6449 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6450 (dont_register_blocks, bytes_used_when_reconsidered)
6451 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6452 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6453 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6454 Remove. All uses removed.
6455 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6456 implementation, one that depends on whether the new macro
6457 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6459 * atimer.c (run_timers, handle_alarm_signal):
6460 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6461 (handle_async_input, process_pending_signals)
6462 (handle_input_available_signal, init_keyboard):
6463 * nsterm.m (ns_read_socket):
6464 * process.c (wait_reading_process_output):
6465 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6466 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6468 * xterm.c (XTread_socket):
6470 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6471 * eval.c (handling_signal): Remove. All uses removed.
6472 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6473 All uses replaced with the SYNC_INPUT version.
6474 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6476 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6479 * font.c (Ffont_shape_gstring): Remove unused local.
6481 2012-09-16 Glenn Morris <rgm@gnu.org>
6483 * Makefile.in (clean): No longer run nextstep's clean.
6485 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6487 (ns-app): Move here from ns.mk, and simplify.
6488 (clean): Simplify nextstep entry.
6489 * ns.mk: Remove file.
6491 2012-09-17 Kenichi Handa <handa@gnu.org>
6493 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6494 not covert the last few charactes.
6496 2012-09-16 Kenichi Handa <handa@gnu.org>
6498 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6499 here, but just check the validity of glyphs in the glyph-string.
6501 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6503 * window.c (Fwindow_parameter, Fset_window_parameter):
6504 Accept any window as argument (Bug#12452).
6506 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6508 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6509 to ns_term_init to avoid memory leak.
6511 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6512 explicit retain/release.
6513 (ns_term_init): Only allow one display. Initialize outerpool and
6516 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6518 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6519 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6520 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6521 the Microsoft problem in a different way, by altering ../nt/config.nt.
6523 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6538 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6539 by lisp.h. This completes removal of setjmp.h inclusion
6540 erroneously announced in the previous commit. (Bug#12446)
6542 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6545 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6546 not defined as a macro. The latter happens on MS-Windows.
6549 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6551 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6552 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6553 Some instances of '#include <setjmp.h>' removed, if the
6554 only reason for the instance was because "lisp.h" was included.
6555 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6556 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6557 and _longjmp with the new symbols. Emacs already uses _setjmp if
6558 available, so this change affects only POSIXish hosts that have
6559 sigsetjmp but not _setjmp, such as some versions of Solaris and
6560 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6561 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6562 (png_load_body) [HAVE_PNG]:
6563 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6564 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6565 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6566 since PNG requires jmp_buf. This is the only exception to the
6567 general rule that we now use sys_setjmp and sys_longjmp.
6568 This exception is OK since this code does not change the signal
6569 mask or longjmp out of a signal handler.
6571 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6573 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6574 Include "syssignal.h", for 'main_thread'.
6576 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6578 Avoid out-of-range marker position (Bug#12426).
6579 * insdel.c (replace_range, replace_range_2):
6580 Adjust markers before overlays, as suggested by comments.
6581 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6582 Remove redundant check before calling offset_intervals.
6584 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6586 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6587 current buffer (Bug#12387).
6589 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6591 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6593 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6595 Use a more backwards-compatible timer format (Bug#12430).
6596 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6597 vector element, not from the 4th, since PSECS is now at the end.
6598 (Fcurrent_idle_time): Doc fix.
6600 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6602 Function to mark objects and remove killed buffers at once.
6603 * alloc.c (discard_killed_buffers): Rename to ...
6604 (mark_discard_killed buffers) ... new name. Add marking
6605 of remaining objects. Fix comment. Adjust users.
6606 (mark_object): Do not touch frame buffer lists here.
6607 * frame.c (delete_frame): Reset frame buffer lists here.
6609 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6611 Better workaround for GNOME bug when --enable-gcc-warnings.
6612 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6613 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6614 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6616 Simplify SIGIO usage (Bug#12408).
6617 The code that dealt with SIGIO was crufty and confusing, e.g., it
6618 played tricks like "#undef SIGIO" but these tricks were not used
6619 consistently. Simplify mostly by not #undeffing standard symbols,
6620 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6621 or not as we please) rather than "defined SIGIO" (standard symbol
6622 that we probably shouldn't #undef).
6623 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6624 Modules that need it can include it.
6625 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6626 * dispextern.h (ignore_sigio): New decl.
6627 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6628 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6629 * emacs.c (shut_down_emacs):
6630 * keyboard.c (kbd_buffer_store_event_hold):
6631 Use ignore_sigio rather than invoking 'signal' directly.
6632 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6634 (FIONREAD, SIGIO): Do not #undef.
6635 (tty_read_avail_input): Use #error rather than a syntax error.
6636 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6637 for I_PIPE, used by SETUP_SLAVE_PTY.
6638 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6639 * sysdep.c (croak): Remove; no longer needed. This bit of
6640 temporary code, with Fred N. Fish's comment that it's temporary,
6641 has been in Emacs since at least 1992!
6642 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6643 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6644 * syssignal.h (croak): Remove decl.
6645 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6646 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6647 now that we're termios-only.
6648 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6649 * term.c (dissociate_if_controlling_tty): Use #error rather than
6652 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6653 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6654 to work around GNOME bug 683906.
6655 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6656 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6657 This works around GCC bug 54561.
6659 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6661 More fixes for 'volatile' and setjmp/longjmp.
6662 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6663 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6664 (png_load_body) [HAVE_PNG]:
6665 (jpeg_load_body) [HAVE_JPEG]:
6666 New function, with most of the old parent function's body.
6667 (png_load) [HAVE_PNG]:
6668 (jpeg_load) [HAVE_JPEG]:
6669 Invoke the new function, to avoid longjmp munging our locals.
6670 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6671 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6672 longjmp is passed 2, as the C standard doesn't guarantee this.
6673 Instead, store the failure code into mgr->failure_code.
6675 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6677 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6678 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6679 (syms_of_keyboard): Remove support for unread-command-char.
6681 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6683 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6684 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6685 violation. (Bug#12426)
6687 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6689 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6691 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6693 * eval.c: Add `inhibit-debugger'.
6694 (Qinhibit_debugger): New symbol.
6695 (call_debugger): Bind it instead of Qdebug_on_error.
6696 (maybe_call_debugger): Test Vinhibit_debugger.
6697 (syms_of_eval): Define inhibit-debugger.
6698 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6699 (syms_of_xdisp): Remove inhibit-debug-on-message.
6701 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6703 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6704 If a nonvolatile local variable is written before a _longjmp to
6705 the frame containing the variable, and is read after the _longjmp,
6706 the value read is indeterminate. Some local variables of type
6707 'struct handler' and 'struct catchtag' are used in this way, so
6708 mark each of their slots as volatile if the slot can be set before
6709 _longjmp and read afterwards.
6710 * lisp.h (struct handler): var and chosen_clause are now volatile.
6711 (struct catchtag): val, next, and pdlcount are now volatile.
6713 * bidi.c (bidi_push_it, bidi_pop_it):
6714 * fns.c (copy_hash_table):
6715 * image.c (define_image_type):
6716 * keyboard.c (kbd_buffer_store_event_hold):
6717 * process.c (Fprocess_send_eof):
6718 * xfaces.c (x_create_gc) [HAVE_NS]:
6719 * xgselect.c (xg_select):
6720 Prefer assignment to memcpy when either will do.
6722 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6723 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6724 time an item is removed. No need to mark this function 'inline';
6725 the compiler knows better than we do.
6727 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6729 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6730 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6731 to change_frame_size (Bug#12388).
6732 (windowDidResize:): Pass YES to updateFrameSize.
6734 * nsterm.h: Add delay parameter to updateFrameSize.
6736 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6738 Discard killed buffers from deleted window and frame objects.
6739 This reduces an amount of references to killed buffers and
6740 helps GC to reclaim them faster.
6741 * alloc.c (discard_killed_buffers): New function.
6742 (mark_object): Use it for deleted windows and frames.
6743 (mark_object): If symbol's value is set up for a killed buffer
6744 or deleted frame, restore its global binding.
6745 * data.c (swap_in_global_binding): Add GC notice.
6746 (swap_in_symval_forwarding): Use convenient set_blv_where.
6747 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6748 * window.h: ... to here.
6750 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6752 Convenient macro to check whether the buffer is live.
6753 * buffer.h (BUFFER_LIVE_P): New macro.
6754 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6755 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6757 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6759 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6760 composition cases (Bug#12364).
6762 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6763 overhang of succeeding glyphs overlapping box cursor.
6765 * w32term.c (x_draw_glyph_string): Likewise.
6767 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6769 Simplify, document, and port floating-point (Bug#12381).
6770 The porting part of this patch fixes bugs on non-IEEE platforms
6771 with frexp, ldexp, logb.
6772 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6774 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6775 support, by removing commented-out code and briefly listing the
6776 C89 functions excluded. The commented-out stuff was confusing
6777 maintenance, e.g., we thought we needed cbrt but it was commented out.
6778 (logb): Remove decl; no longer needed.
6779 (isfinite): New macro, if not already supplied.
6780 (isnan): Don't replace any existing macro.
6781 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6782 are present on all C89 platforms.
6783 (Ffrexp): Do not special-case zero, as frexp does the right thing
6785 (Flogb): Do not use logb, as it doesn't have the desired meaning
6786 on hosts that use non-base-2 floating point. Instead, stick with
6787 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6788 frexp, to avoid getting an unspecified result.
6790 * xdisp.c (Qinhibit_debug_on_message): Now static.
6792 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6794 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6795 NSBezierPath (Bug#12131).
6797 2012-09-10 Chong Yidong <cyd@gnu.org>
6799 * fns.c (Fdelq, Fdelete): Doc fix.
6801 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6803 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6804 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6806 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6808 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6809 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6812 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6814 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6815 left fringe if the window has a left margin. This avoids leaving
6816 traces of the cursor because its leftmost pixel is not drawn over.
6818 * dispnew.c (update_window_line): When the left margin area of a
6819 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6820 that screen line. (Bug#12277)
6822 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6824 Assume C89 or later for math functions (Bug#12381).
6825 This simplifies the code, and makes it a bit smaller and faster,
6826 and (most important) makes it easier to clean up signal handling
6827 since we can stop worring about floating-point exceptions in
6828 library code. That was a problem before C89, but the problem
6829 went away many years ago on all practical Emacs targets.
6830 * data.c, image.c, lread.c, print.c:
6831 Don't include <math.h>; no longer needed.
6832 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6833 might be autoconfigured, as that never happens.
6835 * doprnt.c (DBL_MAX_10_EXP):
6836 * print.c (DBL_DIG):
6837 Remove. C89 or later always defines these.
6838 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6839 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6840 (arith_error, domain_error, domain_error2):
6841 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6842 no longer needed -- we simply return what C returns. All uses removed.
6843 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6845 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6846 Remove. All uses expanded, as these macros are no longer used
6847 more than once and are now more trouble than they're worth.
6848 (Ftan): Use tan, not sin / cos.
6849 (Flogb): Assume C89 frexp.
6850 (fmod_float): Assume C89 fmod.
6851 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6852 (init_floatfns): Remove. All uses removed.
6854 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6856 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6857 compositeToPoint for OSX < 10.6 (Bug#12390).
6859 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6861 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6862 This produces more-accurate results.
6864 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6866 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6867 changes (Bug#12088).
6869 2012-09-08 Chong Yidong <cyd@gnu.org>
6871 * syntax.c (Fstring_to_syntax): Doc fix.
6873 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6875 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6876 in the internal border.
6877 (x_set_window_size): Remove static variables and their usage.
6878 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6879 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6880 Remove fringe/internal border adjustment (Bug#11052).
6881 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6882 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6883 (ns_fix_rect_ibw): Remove.
6884 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6885 (ns_dumpglyphs_box_or_relief): Ditto.
6886 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6888 (ns_dumpglyphs_image): Ditto.
6889 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6891 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6892 their usage. Add fringe_extended_p and its use as in other terms.
6893 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6894 scroll bar was removed.
6895 (updateFrameSize): New function.
6896 (windowDidResize): Move code to updateFrameSize and call it.
6898 * nsterm.h (EmacsView): Add updateFrameSize.
6900 2012-09-07 Chong Yidong <cyd@gnu.org>
6902 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6904 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6906 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6908 More signal-handler cleanup (Bug#12327).
6909 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6910 Problem introduced when merging patches. Noted by Eli Zaretskii in
6911 <http://bugs.gnu.org/12327#67>.
6912 * floatfns.c: Comment fix.
6913 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6914 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6915 and anyway the declaration is harmless even if SIGDANGER is not defined.
6916 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6917 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6918 source files not surprisingly expected syssignal.h to define, or
6919 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6920 Include <sys/ioctl.h>, for FIONREAD.
6921 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6922 This eliminates a problem whereby other files mysteriously had
6923 to include "syssignal.h" before including "systty.h" if they
6924 wanted to use "#ifdef SIGIO".
6926 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6928 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6930 * w32.c (sigemptyset): Empty the set.
6931 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6933 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6935 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6937 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6938 (mark_object): Likewise for frame objects.
6940 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6942 * syssignal.h (handle_on_main_thread): Always declare,
6943 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6944 This ports to platforms without HAVE_PTHREAD.
6946 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6948 Signal-handler cleanup (Bug#12327).
6949 Emacs's signal handlers were written in the old 4.2BSD style with
6950 sigblock and sigmask and so forth, and this led to some
6951 inefficiencies and confusion. Rewrite these to use
6952 pthread_sigmask etc. without copying signal sets around. Also,
6953 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6954 'signal', and instead use functions that do not attempt to take
6955 over the system name space. This patch causes Emacs's text
6956 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6957 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6958 Do not include <signal.h> or "syssignal.h", as these
6959 modules do not use signals.
6960 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6961 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6962 Do not include <signal.h>, as "syssignal.h" does that for us now.
6963 * atimer.c (sigmask_atimers): New function.
6964 (block_atimers, unblock_atimers): New functions,
6965 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6967 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6968 no longer needed here.
6969 * emacs.c (main): Inspect existing signal handler with sigaction,
6970 so that there's no need to block and unblock SIGHUP.
6971 * sysdep.c (struct save_signal): New member 'action', replacing
6972 old member 'handler'.
6973 (save_signal_handlers, restore_signal_handlers):
6974 Use sigaction instead of 'signal' to save and restore.
6975 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6976 New function. All users of 'signal' modified to use set_sighandler
6977 if they're writeonly, and to use sys_signal if they're read+write.
6978 (emacs_sigaction_init, forwarded_signal): New functions.
6979 (sys_signal): Remove. All uses replaced by calls to sigaction
6980 and emacs_sigaction_init, or by direct calls to 'signal'.
6981 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6982 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6983 all uses replaced by pthread_sigmask etc. calls.
6984 * syssignal.h: Include <signal.h>.
6985 (emacs_sigaction_init, forwarded_signal): New decls.
6986 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6987 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6988 (sigmask, sys_sigmask): Remove; no longer needed.
6989 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6990 (sigblock, sigunblock, sigfree):
6991 (sigsetmask) [!defined sigsetmask]:
6992 Remove. All uses replaced by pthread_sigmask.
6993 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6994 no longer need to be replaced, and its typical old uses
6995 are now done via emacs_sigaction_init and sigaction.
6996 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6997 (sys_sigdel): Remove; unused.
6998 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7000 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7002 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7003 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7005 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7007 Explicitly mark buffer_defaults and buffer_local_symbols.
7008 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7009 mark_local_symbols here.
7010 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7011 since special buffers aren't marked here any more.
7012 (allocate_buffer): Chain new buffer with all_buffers here...
7013 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7015 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7016 (syms_of_buffer): Remove staticpro of the above.
7017 (init_buffer_once): Set names for buffer_defaults and
7018 buffer_local_symbols.
7020 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7022 Use bool for booleans in font-related modules.
7023 * font.c (font_intern_prop, font_style_to_value)
7024 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7025 (generate_otf_features, font_check_otf_features, font_check_otf)
7026 (font_match_p, font_list_entities, font_at):
7027 * fontset.c (fontset_id_valid_p, reorder_font_vector
7028 (fontset_find_font, Fset_fontset_font)
7029 (face_suitable_for_char_p) [0]:
7030 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7031 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7032 (m17n_flt_initialized, ftfont_shape_by_flt):
7033 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7034 * nsfont.m (nsfont_draw):
7035 * w32font.c (w32font_draw):
7036 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7037 Use bool for booleans.
7038 * font.h: Adjust to above API changes.
7039 (struct font, struct font_driver, struct font_driver_list):
7040 Use bool for booleans.
7041 (struct font): Remove useless member encoding_type.
7043 * fontset.c, xftfont.c: Omit unnecessary static decls.
7045 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7047 * alloc.c (mark_object): Revert window marking code
7048 since it's unsafe for the Fset_window_configuration.
7050 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7052 Fix race conditions with signal handlers and errno (Bug#12327).
7053 Be more systematic about preserving errno whenever a signal
7054 handler returns, even if it's not in the main thread. Do this by
7055 renaming signal handlers to distinguish between signal delivery
7056 and signal handling. All uses changed.
7057 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7058 * data.c (deliver_arith_signal): Rename from arith_error.
7059 * dispnew.c (deliver_window_change_signal): Rename from
7060 window_change_signal.
7061 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7062 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7063 * keyboard.c (deliver_input_available_signal): Rename from
7064 input_available_signal.
7065 (deliver_user_signal): Rename from handle_user_signal.
7066 (deliver_interrupt_signal): Rename from interrupt_signal.
7067 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7068 (deliver_child_signal): Rename from sigchld_handler.
7069 * atimer.c (handle_alarm_signal):
7070 * data.c (handle_arith_signal):
7071 * dispnew.c (handle_window_change_signal):
7072 * emacs.c (handle_fatal_signal, handle_danger_signal):
7073 * keyboard.c (handle_input_available_signal):
7074 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7075 * process.c (handle_pipe_signal, handle_child_signal):
7076 New functions, with the actual signal-handling code taken from the
7077 original respective signal handlers, sans the sporadic attempts to
7078 preserve errno, since that's now done by handle_on_main_thread.
7079 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7080 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7081 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7083 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7084 Move initialization of main_thread to sysdep.c's init_signals.
7085 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7086 our usage, and simplifies the mainline code.
7087 (record_child_status_change): New static function, as a helper
7088 for handle_child_signal, and with most of the old child handler's
7090 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7091 (handle_child_signal): Use the above.
7092 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7093 Moved here from emacs.c.
7094 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7095 code moved here from emacs.c's main function.
7096 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7097 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7098 This lets callers save and restore errno properly.
7100 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7102 Remove redundant or unused things here and there.
7103 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7104 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7105 * editfns.c (Fcompare_buffer_substrings): Likewise.
7106 * frame.h (struct terminal, struct font_driver_list):
7107 Remove redundant declarations.
7108 * window.h (Qleft, Qright): Likewise.
7110 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7112 Do not mark objects from deleted buffers, windows and frames.
7113 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7114 (mark_object): Likewise for windows and frames.
7116 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7118 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7119 buffer_defaults and buffer_local_symbols as valid objects.
7120 Return special value to denote them.
7122 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7124 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7125 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7126 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7127 (file_name_absolute_p, Fsubstitute_in_file_name):
7128 (check_executable, check_writable, Ffile_accessible_directory_p)
7129 (Fset_file_selinux_context, Fdefault_file_modes)
7130 (Finsert_file_contents, choose_write_coding_system)
7131 (Fwrite_region, build_annotations, a_write, e_write)
7133 * filelock.c (boot_time_initialized, get_boot_time)
7134 (get_boot_time_1, lock_file_1, within_one_second):
7135 * floatfns.c (in_float):
7136 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7137 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7138 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7139 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7140 * window.c (compare_window_configurations):
7141 Use bool for booleans.
7142 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7143 (Fdefault_file_modes): Now mode_t, not int, for modes.
7144 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7145 (internal_delete_file): Now returns void, not a (boolean) int,
7146 since nobody was looking at the return value.
7147 * lisp.h, window.h: Adjust to above API changes.
7149 * xdisp.c (set_message): Simplify and reindent last change.
7151 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7153 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7155 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7157 * eval.c (call_debugger): Make the function non-static so that we
7158 can call it from set_message.
7160 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7161 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7163 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7165 Give more-useful info on a fatal error (Bug#12328).
7166 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7167 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7168 of doing the work ourselves.
7169 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7170 do most of the work.
7171 (fatal_error_backtrace): New function, taken from the guts
7172 of the old fatal_error_signal, but with a new option to output
7174 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7175 info about the signal than just its number.
7176 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7177 * sysdep.c: Include <execinfo.h>
7178 (emacs_backtrace): New function, taken partly from the previous
7179 code of the 'die' function.
7180 (emacs_abort): Call fatal_error_backtrace rather than abort.
7182 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7184 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7185 eager (load-time) macro-expansion.
7186 * lisp.mk (lisp): Add macroexp.
7188 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7190 Simplify redefinition of 'abort' (Bug#12316).
7191 Do not try to redefine the 'abort' function. Instead, redo
7192 the code so that it calls 'emacs_abort' rather than 'abort'.
7193 This removes the need for the NO_ABORT configure-time macro
7194 and makes it easier to change the abort code to do a backtrace.
7195 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7196 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7197 Remove; sysdep.c's emacs_abort now takes its place.
7198 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7199 'abort' changed to use 'emacs_abort'.
7200 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7201 (abort) [!defined abort]: Rename to ...
7202 (emacs_abort): ... new name.
7203 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7204 the place of the old 'abort' in emacs.c.
7205 * w32.c, w32fns.c (abort): Do not #undef.
7206 * w32.c (emacs_abort): Rename from w32_abort.
7208 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7210 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7211 offsets[j].dv, since the y axis of the screen coordinates points
7212 down, while the y axis of the font definition coordinates points
7213 up. This fixes display of Arabic diacritics such as KASRA and
7214 KASRATAN. (Bug#11860)
7216 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7218 Be more systematic about _setjmp vs setjmp.
7219 * alloc.c (test_setjmp, mark_stack):
7220 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7221 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7222 (png_load, my_error_exit, jpeg_load):
7223 * process.c (send_process_trap, send_process):
7224 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7225 The underscored versions are up to 30x faster on some hosts.
7226 Formerly, the code used setjmp+longjmp sometimes and
7227 _setjmp+_longjmp at other times, with no particular reason to
7228 prefer setjmp+longjmp.
7230 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7232 Fix minor problem found by static checking.
7233 * buffer.c (Fdelete_all_overlays): Return nil.
7235 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7237 * buffer.c (Fdelete_all_overlays): New function.
7239 2012-09-03 Chong Yidong <cyd@gnu.org>
7241 * gtkutil.c: Add extern decl for Qxft.
7243 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7245 * emacs.c, eval.c: Use bool for boolean.
7246 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
7247 (malloc_using_checking) [DOUG_LEA_MALLOC]:
7248 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
7249 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
7250 (main, decode_env_path, Fdaemon_initialized):
7251 * eval.c (call_debugger, Finteractive_p, interactive_p):
7252 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
7253 (maybe_call_debugger, Fbacktrace):
7254 * process.c (read_process_output, exec_sentinel):
7255 Use bool for booleans.
7256 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
7257 All callers changed.
7258 * eval.c (interactive_p): Omit always-true boolean argument
7259 EXCLUDE_SUBRS_P. All callers changed.
7260 * dispextern.h, lisp.h: Reflect above API changes.
7261 * firstfile.c (dummy): Use the address of 'main', whose signature
7262 won't change, instead of the address of 'initialize', whose
7263 signature just changed from int to bool.
7264 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7265 * msdos.c (fatal_error_in_progress): ... from here.
7266 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7268 (redisplay_internal, unwind_redisplay): Simply clear
7269 REDISPLAYING_P when unwinding, instead of saving its previous,
7270 always-false value and then restoring it.
7272 Clean up some extern decls.
7273 Mostly, this hoists extern decls out of .c files and into .h files.
7274 That way, we're more likely to catch errors if the interfaces change.
7275 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7276 declare xg_mark_data.
7277 * dispextern.h (x_frame_parm_handlers):
7279 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)
7280 (Qextra_light, Qlight, Qsemi_light, Qsemi_bold, Qbold, Qextra_bold)
7281 (Qultra_bold, Qoblique, Qitalic):
7282 Move extern decl here from .c file.
7283 * alloc.c (xg_mark_data) [USE_GTK]:
7285 * eval.c (Qlexical_binding):
7286 * fns.c (time) [!HAVE_UNISTD_H]:
7287 * gtkutil.c (Qxft, Qnormal, Qextra_light, Qlight, Qsemi_light)
7288 (Qsemi_bold, Qbold, Qextra_bold, Qultra_bold, Qoblique, Qitalic):
7289 * image.c (Vlibrary_cache, QCloaded_from) [HAVE_NTGUI]:
7290 * lread.c (Qinternal_interpreter_environment):
7291 * minibuf.c (Qbuffer):
7292 * process.c (QCfamily, QCfilter):
7293 * widget.c (free_frame_faces):
7294 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
7295 * xfont.c (x_clear_errors):
7296 * xterm.c (x_frame_parm_handlers):
7297 Remove now-redundant extern decls.

7362 offset adjustment values separately for each cluster. (Bug#11860)
7364 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7365 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7366 about implicit conversions from integer to pointer.

7424 window system declarations.
7426 * frame.h: Move common functions here: set_frame_menubar,
7427 x_set_window_size, x_sync, x_get_focus_frame,
7428 x_set_mouse_position, x_set_mouse_pixel_position,
7429 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7486 for GCC 4.7.1 x86-64.
7488 2012-08-30 Glenn Morris <rgm@gnu.org>
7490 * lread.c (init_lread): For out-of-tree builds, only add the
7491 source directory's site-lisp dir to the load-path if it exists,
7492 consistent with in-tree builds. (Bug#12302)
7494 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>

7513 Handle click on close button as quit.
7515 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7516 Add window_closed and button_values. Add void as return value for
7517 add(Button|String|Split). addButton takes int instead of Lisp_Object.

7728 It was meant to be temporary and it often doesn't work,
7729 because when IDX has side effects the behavior of IDX==IDX
7730 is undefined. See Stefan Monnier in
7731 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.

7742 as that's faster and simpler than static storage. Don't bother
7743 with the g_main_context_query overhead if g_main_context_pending
7744 says no events are pending.
7745 (gfds, gfds_size): Remove these static vars.
7746 (xgselect_initialize): Remove; no longer needed.
7747 All uses and decls removed.
7749 * emacs.c (fatal_error_signal_hook): Remove.
7750 All uses removed. This leftover from old code was always 0.
7752 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7753 * casefiddle.c (casify_object, casify_region):
7754 * casetab.c (set_case_table):
7755 * category.c, category.h (word_boundary_p):
7756 * category.h (CHAR_HAS_CATEGORY):
7757 Use bool for booleans, instead of int.
7759 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7761 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7763 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7765 On assertion failure, print backtrace if available.
7766 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7767 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7768 * Makefile.in (LIB_EXECINFO): New macro.
7771 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7772 * bytecode.c (exec_byte_code):
7773 * callint.c (check_mark, Fcall_interactively):
7774 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7775 (getenv_internal, sync_process_alive, call_process_exited):
7776 * lisp.h (USE_SAFE_ALLOCA):
7777 Use bool for booleans, instead of int.
7778 * lisp.h, process.h: Adjust prototypes to match above changes.
7779 * callint.c (Fcall_interactively): Don't assume the mark's
7780 offset fits in 'int'.
7782 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7784 * buffer.c, buffer.h: Use bool for boolean.
7785 * buffer.c (reset_buffer_local_variables)
7786 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7787 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7788 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7789 (overlay_touches_p, overlay_strings, Foverlay_put)
7790 (report_overlay_modification, call_overlay_mod_hooks):
7791 (mmap_enlarge, mmap_set_vars):
7792 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7793 Use bool for booleans, instead of int.
7794 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7795 since the 1-or-0 return value is always ignored anyway.
7796 (mmap_initialized_p):
7797 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7798 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7800 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7802 * bidi.c: Use bool for boolean.
7803 This is a bit more readable, and makes the text segment of bidi.o
7804 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7805 Presumably it's faster too.
7806 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7808 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7809 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7810 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7811 (bidi_explicit_dir_char, bidi_level_of_next_char)
7812 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7813 Use bool for booleans, instead of int.
7814 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7815 (bidi_unshelve_cache): Adjust decls to match code.
7817 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7819 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7822 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7824 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7825 * atimer.h: Include <stdbool.h>.
7827 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7829 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7830 compile time tests instead of run time tests on systems that do
7832 (FRAME_MAC_P): Remove leftover from deleted code.
7833 * frame.c (syms_of_frame): Remove leftover from deleted code.
7835 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>

7839 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7841 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7842 Otherwise, the compiler complains about (A?B:C) where B is void
7843 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7844 (fontset_add): Return void, for FONTSET_ADD.
7846 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7848 * alloc.c: Use bool for booleans.
7849 (gc_in_progress, abort_on_gc)
7850 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7851 (dont_register_blocks) [GC_MALLOC_CHECK]:
7852 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7853 (check_string_bytes, make_specified_string, memory_full)
7854 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7855 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7856 (mark_stack, valid_pointer_p, make_pure_string)
7857 (Fgarbage_collect, survives_gc_p, gc_sweep):
7858 Use bool for booleans, instead of int.
7859 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7860 Remove unused local.
7861 * alloc.c (PURE_POINTER_P):
7862 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7863 * editfns.c (Fformat):
7864 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7866 * fns.c (sweep_weak_table):
7867 * lisp.h (suppress_checking, push_message, survives_gc_p)
7868 (make_pure_string, gc_in_progress, abort_on_gc):
7869 * lread.c (readchar, read1):
7870 * print.c (Fprin1_to_string):
7871 * xdisp.c (push_message):
7872 Use bool for booleans affected directly or indirectly by
7875 Make recently-introduced setters macros.
7876 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7877 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7878 (set_fontset_default, set_fontset_fallback): Rename from their
7879 upper-case counterparts, and make them functions rather than macros.
7880 This is more consistent with the other recently-introduced setters.
7881 These don't need to be inline, since they're local.
7883 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7885 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7886 the loop (Bug#12247).
7888 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7890 * lisp.h (vcopy): Use memcpy rather than our own loop.
7891 This fixes a performance regression introduced by the recent
7892 addition of vcopy. This means 'vcopy' will need to be modified
7893 for a copying collector, but that's OK. Also, tighten the
7894 checking in the assertion.
7896 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7898 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7899 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7900 non-base glyph for the width of the base character, according to
7901 what x_draw_composite_glyph_string_foreground expects.
7902 Generate WADJUST value according to composition_gstring_width's
7903 expectations, to produce correct width of the composed character.
7904 Reverse the sign of the DU offset produced by ScriptPlace.
7906 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7908 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7910 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7912 Avoid direct writes to contents member of struct Lisp_Vector.
7913 * lisp.h (vcopy): New function to copy data into vector.
7914 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7915 * fns.c (Ffillarray): Use ASET.
7916 * keyboard.c (timer_check_2): Use AREF and ASET.
7917 (append_tool_bar_item, Frecent_keys): Use vcopy.
7918 * lread.c (read_vector): Use ASET.
7919 * msdos.c (Frecent_doskeys): Use vcopy.
7920 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7921 (Finternal_merge_in_global_face): Use ASET and vcopy.

7927 the position of its buffer's point.
7928 (Fset_window_point): For the selected window always go in its
7929 buffer to the specified position.
7931 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7933 Setter macros for fontsets.
7934 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7935 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7936 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7939 2012-08-20 Glenn Morris <rgm@gnu.org>
7941 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7942 Don't assume that `ln -f' works.
7944 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7946 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7947 and later about non-assignments with no effect. See discussion at
7948 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7951 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7953 Inline setter functions for Lisp_Objects slots of struct specbinding.
7954 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7957 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7959 * window.c (select_window): Always make selected window's buffer
7962 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7964 Use AREF and ASET for docstrings of category tables.
7965 * category.h (CATEGORY_DOCSTRING): Use AREF.
7966 (SET_CATEGORY_DOCSTRING): Use ASET.
7967 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7969 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7971 Inline setter functions for hash table members.
7972 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7973 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7974 (set_hash_key_and_value, set_hash_index, set_hash_next)
7975 (set_hash_hash): New functions.
7976 * charset.c, fns.c: Adjust users.
7978 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7980 Inline getter and setter functions for per-buffer values.
7981 * buffer.h (per_buffer_default, set_per_buffer_default)
7982 (per_buffer_value, set_per_buffer_value): New functions.
7983 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7984 * buffer.c, data.c: Adjust users.
7986 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7988 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7990 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7992 Rely on <config.h> + <unistd.h> to declare 'environ',
7993 as gnulib does this if the system doesn't.
7994 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7995 Remove declaration. MS-Windows declares it on stdlib.h which is
7996 included by conf_post.h.
7997 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7998 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7999 * vm-limit.c: Include <unistd.h>, for 'environ'.
8001 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8002 (start_of_data): Remove decl; mem-limits.h provides it.
8004 * xdisp.c (handle_invisible_prop): Make it a bit faster
8005 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8007 2012-08-19 Chong Yidong <cyd@gnu.org>
8009 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8012 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
8014 * .gdbinit: Use call instead of set when calling a function in the
8017 * data.c (set_internal): Don't use set_blv_found.
8018 (Fkill_local_variable): Likewise.
8020 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8022 * nsfont.m (ns_ascii_average_width): Ensure the string
8023 ascii_printable is initialized with a null-terminated character
8024 array. Otherwise, it can contain undesired extra characters.
8026 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8028 port new setting code to Sun C 5.8 2005/10/13
8029 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8030 Return void, not Lisp_Object. Otherwise, the compiler
8031 complains about (A?B:C) where B is void and C is Lisp_Object
8032 when compiling CHAR_TABLE_SET, due to the recent change to
8033 the API of sub_char_table_set_contents.
8035 2012-08-18 Chong Yidong <cyd@gnu.org>
8037 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
8038 for the string case (Bug#3874).
8040 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8042 * buffer.h (BSET): Remove (Bug#12215).

8865 Fix startup warnings about ../site-lisp on MS-Windows. (Bug#11959)
8866 * w32.c (init_environment): Change the default values of many
8867 environment variables in dflt_envvars[] to NULL, to avoid pushing
8868 them into environment when they were not already defined.
8869 Remove the code that deletes site-lisp subdirectories from the default
8870 value of EMACSLOADPATH, as it is no longer needed.
8871 (check_windows_init_file): Now external, not static.
8872 Use Vload_path as is, without adding anything, as this function is now
8873 called when Vload_path is already set up.
8875 * w32.h (check_windows_init_file): Add prototype.
8877 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8921 Remove unnecessary pointer casts.
8922 * alloc.c (record_xmalloc): New function.
8923 * lisp.h (record_xmalloc): New decl.
8924 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8925 more like a function. This is because the pointer cast is not
8926 needed. All uses changed.
8927 * print.c (print_string, print_error_message): Avoid length recalc.
8929 Improve fix for macroexp crash with debugging (Bug#12118).
8930 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8931 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8932 not supposed to be invoked from the garbage collector.

8934 (gc_aset): New function, which is like ASET but can be
8935 used in the garbage collector.

8964 with addition of handling of symlinks and support for 'lstat'.
8965 If possible, get file's attributes and security information by
8966 handle, not by name. Produce S_IFLNK bit for symlinks, when
8967 called from 'lstat'.
8968 (stat, lstat): New functions, call 'stat_worker'.
8969 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8970 symlinks when the underlying filesystem supports them.
8972 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
8974 Fix macroexp crash on Windows with debugging (Bug#12118).
8975 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
8976 checking subscripts; problem introduced with the recent
8977 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
8978 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
8979 since it's used in non-static inline functions now.
8981 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
8982 Don't assume buffer size fits in 'int'. Remove unused local.

9002 * composite.c (COMPOSITE_INLINE):
9003 * dispnew.c (DISPEXTERN_INLINE):
9004 * sysdep.c (SYSTIME_INLINE):
9005 Define to EXTERN_INLINE, so that the corresponding functions
9006 are compiled into code.

9008 (INLINE_HEADER_END): New macros.
9009 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9029 hard-coding the path separator.
9031 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9033 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9034 This how ASET and AREF are supposed to work, and makes
9035 it easier to think about future improvements. See
9036 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9037 * charset.h (set_charset_attr): New function.

9526 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9527 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9528 emacs.c, as this is a more-suitable home. Had this been done earlier
9529 the fix for 12036 would have avoided some of the problems noted in
9530 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9531 would have been more obvious.
9532 * emacs.c: Do not include <verify.h>; no longer needed.
9533 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9534 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9535 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9536 Remove; now done in lisp.h.
9537 * lisp.h (PUBLISH_TO_GDB): New macro.

9541 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9542 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9543 not be usable in #if. This simplifies things.
9545 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9547 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9549 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

9552 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9553 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9554 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9555 Adjust to changes in lisp.h and emacs.c, by using
9556 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9557 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9558 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9559 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9560 instead of gdb_valbits.
9561 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9562 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9563 instead of gdb_array_mark_flag.
9564 (xboolvector): Get size from $->size, not $->header.size.
9565 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9566 (xreload, hook-run, hookpost-run): Remove.
9567 * emacs.c: Include <verify.h>.
9568 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9569 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9571 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9572 (gdb_USE_LSB_TAG): New enum constants.
9573 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9574 Also define these as enum constants, so they're visible to GDB.
9575 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9576 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9577 as constants, so they're visible to GDB.

9579 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9580 Now enum constants, not macros, so they're visible to GDB.
9581 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9582 more convenient now. All uses changed.
9583 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9584 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9586 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9593 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9594 add argument, tune behavior, and adjust all callers.
9596 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9598 Use typedef for EMACS_INT, EMACS_UINT.
9599 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9600 than macros. This simplifies debugging in the usual case, since
9601 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9602 and it allows expressions involving EMACS_INT casts.
9603 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9605 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9617 Adjust buffer text indirection counters at the end of Fkill_buffer.
9618 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9619 buffer is definitely dead. This should really fix an issue reported
9620 by Christoph Scholtes again. (Bug#12007).
9621 (init_buffer_once): Initialize indirection counters of
9622 buffer_defaults and buffer_local_symbols (for sanity and safety).
9624 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9626 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9627 and continuation glyphs on tooltip frames, leave them at zero.

9655 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9657 Swap buffer text indirection counters in Fbuffer_swap_text.
9658 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9659 This avoids crash reported by Christoph Scholtes at
9660 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9662 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9664 * nsmenu.m (Popdown_data): New struct.

9687 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9689 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9690 as it's limited by the amount of memory, not by INT_MAX.
9692 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9694 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'

9845 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9847 * eval.c (Fdefvar): Don't check constants since we only set the var if
9848 it's not yet defined anyway (bug#11904).
9850 * lisp.h (last_undo_boundary): Declare new var.
9851 * keyboard.c (command_loop_1): Set it.
9852 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
9853 were auto-added by the command loop (bug#11774).

10398 Adjust users accordingly.
10399 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
10401 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
10402 Change to return ptrdiff_t.
10403 (xfont_list_pattern, xfont_match): Use length returned by
10404 xfont_decode_coding_xlfd.

10407 2012-07-11 Glenn Morris <rgm@gnu.org>
10409 * s/darwin.h, s/freebsd.h, s/netbsd.h:
10410 Move DONT_REOPEN_PTY to configure.
10412 * sound.c (DEFAULT_SOUND_DEVICE) [!WINDOWSNT]:
10413 * s/netbsd.h (DEFAULT_SOUND_DEVICE): Let configure set it.
10415 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
10417 Remove "#define unix" that is no longer needed (Bug#11905).
10418 * s/aix4-2.h (unix): Remove; no longer needed.
10420 EMACS_TIME simplification (Bug#11875).
10421 This replaces macros (which typically do not work in GDB)
10422 with functions, typedefs and enums, making the code easier to debug.
10423 The functional style also makes code easier to read and maintain.
10424 * systime.h: Include <sys/time.h> on all hosts, not just if
10425 WINDOWSNT, since 'struct timeval' is needed in general.
10426 (EMACS_TIME): Now a typedef, not a macro.
10427 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
10429 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
10430 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

10433 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
10434 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
10435 which are not functions. All uses rewritten to use:
10436 (make_emacs_time): New function.
10437 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
10438 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
10439 not functions. All uses rewritten to use the following, respectively:
10440 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
10441 (add_emacs_time, sub_emacs_time): New functions.
10442 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
10443 * fileio.c (Fcopy_file):
10444 * xterm.c (XTflash): Get the current time closer to when it's used.
10445 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
10447 * bytecode.c (targets): Suppress -Woverride-init warnings.

10450 * doc.c (Fsnarf_documentation):
10451 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
10452 * frame.c (Fmake_terminal_frame):
10453 * gtkutil.c (get_utf8_string):
10455 * nsmenu.m (ns_update_menubar):
10456 * regex.c (regerror):
10457 Prefer memcpy to strncpy and strncat when either will do.
10458 * fileio.c (Fsubstitute_in_file_name):
10459 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
10460 (menu_separator_name_p):
10461 * nsmenu.m (ns_update_menubar):
10462 Prefer memcmp to strncmp when either will do.
10463 * nsterm.m: Include <ftoastr.h>.
10465 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10466 Prefer snprintf to strncpy.
10467 * nsterm.m (ns_term_init):
10468 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10469 * nsterm.m (ns_term_init):
10470 Avoid the need for strncpy, by using build_string or
10471 make_unibyte_string directly. Use dtoastr, not snprintf.
10472 * process.c (Fmake_network_process): Diagnose service names that
10473 are too long, rather than silently truncating them or creating
10474 non-null-terminated names.
10475 (Fnetwork_interface_info): Likewise, for interface names.
10476 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10477 Prefer sprintf to strncat.
10478 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10479 Prefer vsnprintf to vsprintf + strncpy.
10481 2012-07-10 Glenn Morris <rgm@gnu.org>
10483 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
10484 Clarify fallback case.
10486 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10488 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10489 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10490 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10491 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10492 where argument type is known to be a Lisp_Cons.
10494 2012-07-10 Tom Tromey <tromey@redhat.com>
10496 * bytecode.c (BYTE_CODE_THREADED): New macro.
10497 (BYTE_CODES): New macro. Replaces all old byte-code defines.
10498 (enum byte_code_op): New type.
10499 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
10500 (exec_byte_code): Use them. Use token threading when applicable.
10502 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10504 Optimize pure C strings initialization.
10505 * lisp.h (make_pure_string): Fix prototype.
10506 (build_pure_c_string): New function, defined as static inline. This
10507 provides a better opportunity to optimize away calls to strlen when
10508 the function is called with compile-time constant argument.
10509 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10510 argument, adjust users accordingly. Use build_pure_c_string where
10512 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10513 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10514 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10516 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10518 Avoid calls to strlen in miscellaneous functions.
10519 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10520 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10521 * lread.c (openp): Likewise.
10523 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10525 Avoid calls to strlen in path processing functions.
10526 * fileio.c (file_name_as_directory): Add comment. Change to add
10527 srclen argument and return the length of result. Adjust users
10529 (directory_file_name): Fix comment. Change to add srclen argument,
10530 swap 1st and 2nd arguments to obey the common convention.
10531 Adjust users accordingly.
10532 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10534 2012-07-10 Glenn Morris <rgm@gnu.org>
10536 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
10537 Move PENDING_OUTPUT_COUNT definition to configure.
10539 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10540 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10541 * s/gnu.h (DATA_START): Move definitions to configure.
10543 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10544 We include usg5-4-common.h, which defines them both.
10546 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10547 O_RDONLY already includes it).
10549 Stop ns builds setting the EMACSLOADPATH environment variable.
10550 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10551 Now it does not set EMACSLOADPATH, just returns the load-path string.
10552 * nsterm.h: Update accordingly.
10553 * lread.c [HAVE_NS]: Include nsterm.h.
10554 (init_lread) [HAVE_NS]: Use ns_load_path.
10555 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10557 2012-07-09 Glenn Morris <rgm@gnu.org>
10559 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10560 since the included bsd-common.h does so.
10562 Stop ns builds setting the EMACSPATH environment variable.
10563 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10564 (ns_init_paths): Do not set EMACSPATH.
10565 * nsterm.h (ns_exec_path): Add it.
10566 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10569 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10571 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10573 * process.c (wait_reading_process_output): 'waitchannels' was unset
10574 when read_kbd || !NILP (wait_for_cell); fix this.
10576 Add GCC-style 'const' attribute to functions that can use it.
10577 * character.h (char_resolve_modifier_mask):
10578 * keyboard.h (make_ctrl_char):
10579 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10580 (init_character_once, next_almost_prime, init_fns, init_image)
10581 (flush_pending_output, init_sound):
10582 * mem-limits.h (start_of_data):
10583 * menu.h (finish_menu_items):

10588 Add decls with ATTRIBUTE_CONST.
10590 Minor improvements to make_formatted_string.
10591 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10592 where int is good enough, as vsprintf returns an int.
10593 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10595 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10597 Use make_formatted_string to avoid double length calculation.
10598 * lisp.h (make_formatted_string): New prototype.
10599 * alloc.c (make_formatted_string): New function.

10605 (x_report_frame_params): Likewise.
10606 * image.c (gs_load): Likewise.
10607 * minibuf.c (get_minibuffer): Likewise.
10608 * msdos.c (dos_set_window_size): Likewise.
10609 * process.c (make_process): Likewise.
10610 * xdisp.c (ensure_echo_area_buffers): Likewise.
10611 * xsettings.c (apply_xft_settings): Likewise.
10613 2012-07-09 Glenn Morris <rgm@gnu.org>
10615 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10616 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10617 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10620 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10622 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10624 Move marker debugging code under MARKER_DEBUG.
10625 * marker.c (MARKER_DEBUG): Move marker debugging code under
10626 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10627 for bootstrap with --enable-checking (~3x slowdown reported
10628 by Juanma Barranquero <lekktu@gmail.com>).
10629 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10631 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10633 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10634 See <http://bugs.gnu.org/11825#29>.
10636 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10638 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10639 has no font, use the frame's font. (Bug#11813)
10640 (display_line): Add commentary about displaying truncation glyphs
10642 (produce_special_glyphs): Move here from term.c.
10644 * term.c (produce_special_glyphs): Move to xdisp.c.
10646 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10649 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10651 * xdisp.c (display_line): Avoid warning about implicit declaration
10654 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10656 * lisp.h: Remove empty conditional.
10658 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10660 * lread.c (load_path_check): Now static.
10662 Fix some minor --with-ns problems found by static checking.
10663 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10664 (x_set_font) [!HAVE_X_WINDOWS]:
10665 * image.c (xpm_load_image) [HAVE_NS]:
10666 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10667 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10668 Remove unused local.
10669 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10670 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10671 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10672 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10673 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10674 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10675 Fix pointer signedness problem.
10676 * xfaces.c (FRAME_X_FONT_TABLE):
10677 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10679 2012-07-07 Glenn Morris <rgm@gnu.org>
10681 * lread.c (load_path_check): New function, split from init_lread.
10682 (init_lread): Reorganize. Motivation:
10683 If EMACSLOADPATH is set, check/warn about that rather than the
10684 defaults, which we are not going to use. Hence we can remove
10685 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10686 Don't warn if site-lisp directories are missing.
10687 If not installed, start from a blank load-path, since
10688 PATH_LOADSEARCH refers to the eventual installation directories.
10690 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10692 Support truncation and continuation glyphs on GUI frames, when
10693 fringes are disabled. (Bug#11832)
10694 * xdisp.c (init_iterator): Get dimensions of truncation and
10695 continuation glyphs even if on GUI frames.
10696 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10697 or both, are absent.
10698 (start_display, move_it_in_display_line_to): Handle the case of a
10699 GUI frame without a fringe to display continuation or truncation
10701 (insert_left_trunc_glyphs): Support GUI frames: make sure
10702 truncation glyphs overwrite enough glyphs from the current line to
10703 have sufficient space in pixels.
10704 (display_line): Support truncation and continuation glyphs on GUI
10705 frames. If some spare pixels are left on the line after inserting
10706 the truncation glyphs, fill that space with a stretch glyph of a
10707 suitably computed width.
10709 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10710 produce_glyphs, to support GUI sessions.
10712 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10714 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10716 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10718 Do not require float-time's arg to fit in time_t (Bug#11825).
10719 This works better on hosts where time_t is unsigned, and where
10720 float-time is applied to the (negative) difference between two times.
10721 * editfns.c (decode_time_components): Last arg is now double *,
10722 not int *, and means to store all the result as a double, without
10723 worrying about whether the seconds part fits in time_t.
10724 All callers changed.
10725 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10726 All callers changed.
10727 (Ffloat_time): Do not fail merely because the specified time falls
10728 outside of time_t range.
10730 2012-07-07 Glenn Morris <rgm@gnu.org>
10732 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10733 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10734 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10736 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10738 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10739 Update dependencies.
10741 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10743 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10745 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
10746 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
10747 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10748 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10749 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10750 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10752 * xfont.c (compare_font_names): Redo to omit the need for casts.
10754 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10756 * xfns.c (Fx_change_window_property): Doc fix.
10757 * w32fns.c (Fx_change_window_property): Doc fix.
10759 * w32fns.c (Fx_window_property): Accept the same arguments as the
10760 X Windows version. Doc fix.
10761 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10763 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10764 Eli Zaretskii <eliz@gnu.org>
10766 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10767 Windows-specific code from nt/config.nt moved here.
10768 Obsolete settings removed.
10770 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10772 * process.c: Avoid unnecessary calls to gettime.
10773 (wait_reading_process_output): Don't get the time of day
10774 when gobbling data immediately and not waiting, as there's no need
10775 for it in that case. This removes a FIXME.
10777 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10779 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10780 is defined (Bug#11768).
10782 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10784 Fix marker debugging code.
10785 * marker.c (byte_char_debug_check): Do not perform the check
10786 if buffer is not multibyte.
10787 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10788 Call byte_char_debug_check with correct arguments.
10790 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10792 Compile marker debugging code only if ENABLE_CHECKING is defined.
10793 * marker.c (byte_char_debug_check, count_markers):
10794 Use only if ENABLE_CHECKING is defined.
10795 (byte_debug_flag): Remove.
10796 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10797 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10799 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10801 Avoid code repetition in marker-related functions.

10821 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
10822 * composite.c (autocmp_chars): Likewise.
10823 * editfns.c (buildmark): Remove.
10824 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10825 (save_restriction_save): Use build_marker.
10826 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10827 * window.c (save_window_save): Likewise.
10829 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10831 Do not use Fdelete_overlay in delete_all_overlays
10832 to avoid redundant calls to unchain_overlay.
10833 * buffer.c (drop_overlay): New function.
10834 (delete_all_overlays, Fdelete_overlay): Use it.
10835 * minibuf.c (get_minibuffer): Fix comment.
10837 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10839 Port to OpenBSD 5.1 amd64.
10840 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10841 This is needed for OpenBSD, and should be harmless on all BSD systems.
10842 Also, include <sys/sysctl.h>, as it should be available on all
10843 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10844 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10845 use p_pid member, not kp_proc.pid.
10847 2012-07-06 Glenn Morris <rgm@gnu.org>
10849 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10851 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10853 More xmalloc and related cleanup.
10854 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

10862 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10864 Omit needless casts involving void * pointers and allocation.
10865 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10866 as the former is more robust if P's type is changed.
10867 Prefer xzalloc to xmalloc + memset 0.
10868 Simplify malloc-or-realloc to realloc.
10869 Don't worry about xmalloc returning a null pointer.
10870 Prefer xstrdup to xmalloc + strcpy.
10871 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10873 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10874 alloca of a constant.
10876 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10878 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10879 hscroll is larger than the line width. Fixes long and futile
10880 looping inside extend_face_to_end_of_line (on a TTY) producing
10881 glyphs that are not needed and thrown away.
10883 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10885 * marker.c (set_marker_restricted_both): Simplify by using
10888 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10890 * editfns.c (region_limit): Simplify by using clip_to_bounds.
10892 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
10894 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10895 not defined (Bug#11768).
10896 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10897 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
10898 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
10899 followed by gtk_box_set_homogeneous (Bug#11768).
10900 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10901 (update_theme_scrollbar_width, xg_create_scroll_bar):
10902 Use gtk_scrollbar_new (Bug#11768).
10903 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10904 (is_box_type): New function (Bug#11768).
10905 (xg_tool_item_stale_p): Call is_box_type.
10906 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10907 with default display (Bug#11768).
10909 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10911 * xdisp.c (window_hscroll_limited): New function.
10912 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10913 coordinates when window's hscroll is set to insanely large
10914 values. (Bug#11857)
10916 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10977 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10979 * fileio.c (time_error_value): Check the right error number.
10980 Problem reported by Troels Nielsen in
10981 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10983 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10985 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10986 This should be fixed in a better way; see Eli Zaretskii in
10987 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10988 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10990 * fileio.c (time_error_value): Rename from special_mtime.
10991 The old name's problems were noted by Eli Zaretskii in
10992 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10994 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10995 This variable's comment says Emacs needs at least one GDB-visible
10996 symbol of type enum pvec_type, to work around GDB problems.
10997 The symbol's value doesn't matter.
10999 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11000 that causes compilation to fail on pre-C99 compilers.
11002 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11004 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
11005 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
11007 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11009 * buffer.c (init_buffer_once): Fix initialization of
11010 headers for buffer_defaults and buffer_local_symbols.
11011 Reported by Juanma Barranquero <lekktu@gmail.com>.
11013 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11015 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11016 * lisp.h (enum pvec_type): Use fewer bits.
11017 (PSEUDOVECTOR_SIZE_BITS): New constant.
11018 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11019 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11020 change in pvec_type.
11021 (PSEUDOVECTOR_TYPEP): New macro.
11022 (TYPED_PSEUDOVECTORP): Use it.
11023 * fns.c (internal_equal): Adapt code to extract pvectype.
11024 * emacs.c (gdb_pvec_type): Update type.
11025 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11026 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11027 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11028 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11029 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11030 abusing vector->header.next.nbytes.
11031 (live_vector_p): Use PVEC_TYPE.
11032 (mark_object): Adapt code to extract pvectype. Use switch.
11034 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11036 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11037 Tighten new eassert a bit.
11039 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11041 Fix compilation with --enable-gcc-warnings and -O1
11042 optimization level.
11043 * doprnt.c (doprnt): Change type of tem to int, initialize
11044 to avoid compiler warning. Add eassert.
11045 * search.c (simple_search): Initialize match_byte to avoid
11046 compiler warning. Add eassert.
11048 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11050 Avoid weird behavior with large horizontal scrolls.
11051 Without this change, for example, large hscroll values would
11052 mess up Emacs's display on Fedora 15 x86, presumably due to
11053 overflows in int calculations in the display code.
11054 Also, if buffers had long lines, Emacs would freeze.
11055 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11056 (set_window_hscroll): New function, containing the old guts of
11057 Fset_window_hscroll. Return the clipped value.
11058 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11059 This avoids the need to check against PTRDIFF_MAX.
11061 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11063 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11065 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11067 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11069 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11070 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11071 since GCC 4.4.6 issues a bogus warning for them.
11073 Fix bugs in file timestamp newness comparisons.
11074 * fileio.c (Ffile_newer_than_file_p):
11075 * lread.c (Fload): Use full timestamp resolution of files,
11076 not just the 1-second resolution, so that files that are only
11077 slightly newer still count as newer.
11078 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11079 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11081 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11083 * fileio.c: Improve handling of file time marker. (Bug#11852)
11084 (special_mtime): New function.
11085 (Finsert_file_contents, Fverify_visited_file_modtime):
11086 Use it to set special mtime values consistently.
11088 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11090 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11091 marker for non-existing file. (Bug#11852)
11093 2012-07-03 Glenn Morris <rgm@gnu.org>
11095 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11096 and did not make it into globals.h).
11098 2012-07-03 Tom Tromey <tromey@redhat.com>
11100 * window.c (Fset_window_margins, Fset_window_fringes)
11101 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11102 * textprop.c (Fprevious_property_change): No longer static.

11124 * dispextern.h: Remove EXFUNs.
11125 * intervals.h: Remove EXFUNs.
11126 * fontset.h: Remove EXFUN.
11127 * font.h: Remove EXFUNs.
11128 * dosfns.c (system_process_attributes): Remove EXFUN.
11129 * keymap.h: Remove EXFUNs.
11130 * lisp.h: Remove EXFUNs.
11131 * w32term.h: Remove EXFUNs.
11132 * window.h: Remove EXFUNs.
11133 * xsettings.h: Remove EXFUN.
11134 * xterm.h: Remove EXFUN.
11136 2012-07-03 Glenn Morris <rgm@gnu.org>
11138 * lisp.h (Frandom): Make it visible to C.
11139 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11140 buffer for invisible buffers. (Bug#1229)
11142 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11144 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11145 values which aren't power of 2.
11146 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11147 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11150 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11152 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11154 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11156 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11158 * alloc.c (allocate_vector_block): Remove redundant
11159 calls to mallopt if DOUG_LEA_MALLOC is defined.
11160 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11161 avoid calls to mallopt if zero_vector is returned.
11163 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11165 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11166 is enabled, avoid dereferencing NULL current_sblock if
11169 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11171 Cleanup basic buffer management.
11172 * buffer.h (struct buffer): Change layout to use generic vector
11173 marking code. Fix some comments. Change type of 'clip_changed'
11174 to bitfield. Remove unused #ifndef old.
11175 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11176 (GET_OVERLAYS_AT): Fix indentation.
11177 (for_each_per_buffer_object_at): New macro.
11178 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
11179 (Fbuffer_local_variables): Use it.
11180 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
11181 * alloc.c (allocate_buffer): Adjust to match new layout of
11182 struct buffer. Fix comment.
11183 (mark_overlay): New function.
11184 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11185 Lisp area of struct buffer.
11186 (mark_object): Use it. Adjust marking of misc objects
11187 and related comments.
11189 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11191 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11192 wrapper that is not needed because the wrapped code is a no-op (zero
11193 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11194 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11196 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11198 * alloc.c (mark_buffer): Simplify. Remove prototype.
11199 (mark_object): Add comment. Reorganize marking of vector-like
11200 objects. Use CHECK_LIVE for all vector-like objects except buffers
11201 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11202 Avoid redundant calls to mark_vectorlike for bool vectors.
11204 2012-06-30 Glenn Morris <rgm@gnu.org>
11206 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11208 * epaths.in (PATH_SITELOADSEARCH): New.
11209 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11210 This is rather than relying on --enable-locallisppath elements
11211 having "site-lisp" in their names. (Bug#10208#25, 11658)
11213 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11215 * w32proc.c (sys_select): Accept and ignore one more argument.
11217 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11219 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11220 (pselect) [!MS_DOS]: Redirect to sys_select.
11222 * sysdep.c: Don't include dos.h and dosfns.h.
11224 * process.c (sys_select):
11225 * msdos.c (sys_select): Accept one more argument and ignore it.
11227 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11228 adapt data types and code to that.
11231 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11232 which clashes with the gnulib function of the same name.
11234 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11236 * font.c (font_style_to_value, font_style_symbolic)
11237 (font_prop_validate_style): Add type checks for values in
11240 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11242 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11245 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11247 * xdisp.c (try_window_id): Undo last change.
11249 * w32.c (getwd): Adjust commentary about startup_dir.
11250 (init_environment): Always call sys_access, even in non-MSVC
11251 builds. Don't chdir to the directory of the Emacs executable.
11252 This undoes code from 1997 which was justified by the need to
11253 "avoid conflicts when removing and renaming directories". But its
11254 downside was that every relative file name was being interpreted
11255 relative to the directory of the Emacs executable, which can never
11256 be TRT. In particular, it broke sys_access when called with
11257 relative file names.
11258 (sys_access): Map GetLastError to errno.
11260 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11262 * window.h (struct window): Change type of 'fringes_outside_margins'
11263 to bitfield. Fix comment. Adjust users accordingly.

11450 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11452 Use sprintf return value instead of invoking strlen on result.
11453 In the old days this wasn't portable, since some sprintf
11454 implementations returned char *. But they died out years ago and
11455 Emacs already assumes sprintf returns int.
11456 Similarly for float_to_string.
11457 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11465 Use sprintf or float_to_string result to avoid need to call strlen.
11466 * data.c (Fnumber_to_string):
11467 Use make_unibyte_string, since the string must be ASCII.
11468 * lisp.h, print.c (float_to_string): Now returns int length.
11469 * term.c (produce_glyphless_glyph):
11470 Use sprintf result rather than recomputing it.
11472 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

11480 strcasecmp if available.

11501 * xfns.c (x_window): Remove redundant cast.
11503 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11505 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11506 `const char *' to `char *' to avoid compiler warning.
11508 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11510 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11511 instead of truncating it to 63 (admittedly a generous limit).
11513 * process.c: Fix spelling and caps in comments.

11564 Remove unnecessary forward decls.
11566 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11568 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

11571 * keyboard.c (kbd_buffer_get_event):
11572 * process.c (Faccept_process_output):
11573 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11574 This improves on the previous patch, which introduced a bug
11575 when time_t is unsigned and as wide as intmax_t.
11576 See <http://bugs.gnu.org/9000#51>.
11578 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11607 language ID in the event parameters.
11609 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11610 event.code, not the obscure "character set ID".

11643 Support higher-resolution time stamps (Bug#9000).
11644 The time stamps are only nanosecond-resolution at the C level,
11645 since that's the best that any real-world system supports now.
11646 But they are picosecond-resolution at the Lisp level, as that's
11647 easy, and leaves room for future OS improvements.
11649 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11652 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11653 Don't get current time unless it's needed.
11655 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11656 now provides it if it's absent.
11657 (start_atimer): Port to higher-res time stamps.
11658 Check for time stamp overflow. Don't get current time more
11659 often than is needed.
11661 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11662 Include systime.h, not time.h.
11663 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11665 * dired.c: Include stat-time.h.
11666 (Ffile-attributes): File times now have higher resolution.
11668 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11669 (struct image): Timestamp now has higher resolution.
11671 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11672 has at least microseconds now. All uses removed.
11673 (update_frame, update_single_window, update_window, update_frame_1)
11674 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11675 (duration_to_sec_usec): Remove; no longer needed.
11677 * editfns.c (time_overflow): Now extern.
11678 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
11679 (float-time, Fformat_time_string, Fcurrent_time_string)

11683 (decode_time_components, lisp_seconds_argument): New functions.
11684 (make_time): Now static.
11685 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11686 Report an error if the time is invalid, rather than having the caller
11689 * fileio.c: Include <stat-time.h>
11690 (Fcopy_file): Copy higher-resolution time stamps.
11691 Prefer to set the time stamp via a file descriptor if that works.
11692 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11693 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11694 (Fvisited_file_modtime, Fset_visited_file_modtime):
11695 Support higher-resolution time stamps.
11697 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11699 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11701 * image.c (prepare_image_for_display, clear_image_cache)
11702 (lookup_image): Port to higer-resolution time stamps.
11704 * keyboard.c (start_polling, bind_polling_period):
11705 Check for time stamp overflow.
11706 (read_char, kbd_buffer_get_event, timer_start_idle)
11707 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11708 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11709 Port to higher-resolution time stamps. Do not assume time_t is signed.
11710 (decode_timer): New function. Timers are now vectors of length 9,
11711 not 8, to accommodate the picosecond component.
11712 (timer_check_2): Use it.
11714 * nsterm.m (select_timeout, timeval_subtract): Remove.
11715 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11716 as they're a bit more accurate and handle overflow better.
11717 (ns_select): Change prototype to be compatible with pselect.
11718 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11719 * nsterm.h (ns_select): Adjust prototype.
11721 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11722 us-resolution time stamps.
11723 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11725 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11727 * lisp.h (time_overflow): New decl.
11728 (wait_reading_process_output): First arg is now intmax_t, not int,
11729 to accommodate larger waits.
11731 * process.h (struct Lisp_Process.read_output_delay):
11732 Now counts nanoseconds, not microseconds.
11733 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11735 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11736 (wait_reading_process_output):
11737 Port to ns-resolution time stamps.
11738 (Faccept_process_output, wait_reading_process_output):
11739 Check for time stamp overflow. Do not assume time_t is signed.
11740 (select_wrapper): Remove; we now use pselect.
11741 (Fprocess_attributes): Now generates ns-resolution time stamps.
11743 * sysdep.c: Include utimens.h. Don't include utime.h
11744 or worry about struct utimbuf; gnulib does that for us now.
11745 (gettimeofday): Remove; gnulib provides a substitute.
11746 (make_timeval): New function.
11747 (set_file_times): Now sets ns-resolution time stamps.
11748 New arg FD; all uses changed.
11749 (time_from_jiffies, ltime_from_jiffies, get_up_time)

11751 Now returns ns-resolution time stamp. All uses changed.
11752 Check for time stamp overflow.

11755 provides a substitute now.
11757 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11758 since it guarantees struct timespec.
11759 (EMACS_TIME): Now struct timespec, so that we can support
11760 ns-resolution time stamps.
11761 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11762 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11763 (EMACS_USECS): Remove.
11764 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11765 so multiply the arg by 1000 before storing it.

11775 (make_timeval, make_lisp_time, decode_time_components): New decls.
11776 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11777 that it mishandled time_t overflow. You can't compare by subtracting!
11778 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11779 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11781 * term.c: Include <sys/time.h>.
11782 (timeval_to_Time): New function, for proper overflow wraparound.
11783 (term_mouse_position, term_mouse_click): Use it.

11786 in the undo buffer.
11787 (Fprimitive_undo): Use them when restoring time stamps.
11789 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11790 (w32_get_internal_run_time):
11791 Port to higher-resolution Emacs time stamps.
11792 (ltime): Now accepts single 64-bit integer, as that's more convenient
11795 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11797 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11798 for compatibility with pselect. Support ns-resolution time stamps.
11800 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11802 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11803 Check for time stamp overflow, and support ns-resolution time stamps.
11805 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11806 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11807 (timeval_subtract): Remove; no longer needed.
11808 (XTflash, XTring_bell, x_wait_for_event):
11809 Port to ns-resolution time stamps. Don't assume time_t is signed.

11815 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11817 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11818 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11819 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11820 staticidx goes up to 1597 out of 1600 = 0x640.)
11822 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11824 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11825 Otherwise, the umask might be mistakenly 0 while handling input signals.
11827 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
11829 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

11845 frame's selected window and its terminal's top-frame.
11846 (unwind_format_mode_line): Restore them.
11847 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11849 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11850 since tty frames can be explicitly named.
11851 (prepare_menu_bars): Likewise.
11853 * term.c (Ftty_top_frame): New function.
11855 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11857 Port byte-code-meter to modern targets.
11858 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11859 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11860 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11861 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

11868 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11870 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11871 gets killed during executing of this function (Bug#11665).
11872 Try to always return Qt when the buffer has been actually killed.
11873 (Vkill_buffer_query_functions): In doc-string say that functions
11874 run by this hook should not change the current buffer.
11876 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11878 Fix recently-introduced process.c problems found by static checking.

11898 * lisp.h (eassert): Assume C89 or later.
11899 This removes the need for CHECK.
11900 (CHECK): Remove. Its comments about always evaluating its
11901 argument were confusing, as 'eassert' typically does not evaluate
11904 * coding.c (produce_chars): Use ptrdiff_t, not int.
11906 * xterm.c (x_draw_underwave): Check for integer overflow.
11907 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

12095 Use an inline function on all platforms when using the union type,

12182 * xdisp.c (vmessage): Treat frame message as multibyte.
12183 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
12184 would generate the diagnostic "Making \302\247 buffer-local while
12187 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12189 * dispnew.c (showing_window_margins_p): Undo last change, which
12190 was done due to an inadvertent commit.
12191 (adjust_frame_glyphs_for_frame_redisplay): Do call
12192 showing_window_margins_p.
12194 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
12196 * eval.c (Fmake_var_non_special): New primitive.

12202 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
12203 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
12205 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12207 * alloc.c (allocate_vectorlike): Fix last change.
12209 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
12211 Block-based vector allocation of small vectors.
12212 * lisp.h (struct vectorlike_header): New field `nbytes',
12213 adjust comment accordingly.
12214 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
12215 to denote vector blocks. Adjust users (live_vector_p,
12216 mark_maybe_pointer, valid_lisp_object_p) accordingly.
12217 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
12218 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES)

12232 (init_alloc_once): Add call to init_vectors.
12234 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
12236 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
12238 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
12240 * doprnt.c (doprnt): Truncate multibyte char correctly.
12241 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12242 would mishandle a string argument "Xc" if X was a multibyte
12243 character of length 2: it would truncate after X's first byte
12244 rather than including all of X.
12246 2012-06-06 Chong Yidong <cyd@gnu.org>
12248 * buffer.c (word_wrap): Doc fix.
12250 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

12262 binary via PaX flags if the paxctl utility is available.
12263 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
12264 Restore PaX flags to their default. (Bug#11398)
12266 2012-06-03 Chong Yidong <cyd@gnu.org>
12268 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte
12269 buffer (Bug#11226).

12273 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
12274 (note_mode_line_or_margin_highlight): If there is no help echo,
12275 use mode-line-default-help-echo. Handle the case where the mouse
12276 position is past the end of the mode line string.
12278 * buffer.c (buffer_local_value_1): New function, split from
12279 Fbuffer_local_value; can return Qunbound.
12280 (Fbuffer_local_value): Use it.
12281 (Vmode_line_format): Docstring tweaks.
12283 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

12295 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12297 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12298 Convert pctcpu and pctmem to Lisp float properly.
12299 Let the compiler fold better, as 100.0/0x8000 is exact.
12301 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12303 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12306 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

12310 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12312 For a 'struct window', replace some Lisp_Object fields to
12313 bitfields where appropriate, remove unused fields.
12314 * window.h (struct window): Remove unused 'last_mark_x' and
12315 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12316 change its type from Lisp_Object to bitfield.
12317 Change type of 'force_start', 'optional_new_start',
12318 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
12319 fields from Lisp_Object to bitfield. Adjust users accordingly.
12321 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12323 Pacify gcc -Wdouble-precision when using Xaw.
12324 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12325 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12326 Use 'float' consistently, rather than 'float' in most places
12327 and 'double' in a couple of places.
12329 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12331 * xdisp.c (handle_stop): Detect whether we have overlay strings
12332 loaded by testing it->current.overlay_string_index to be
12333 non-negative, instead of checking whether n_overlay_strings is
12334 positive. (Bug#11587)
12336 2012-05-31 Chong Yidong <cyd@gnu.org>
12338 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12342 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12344 * search.c (search_buffer): Remove calls to
12345 r_alloc_inhibit_buffer_relocation, as it is now called by
12346 maybe_unify_char, which was the cause of relocation of buffer text
12349 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12351 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12352 for the duration of call to load_charset, to avoid problems with
12353 callers of maybe_unify_char that access buffer text through C
12356 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12357 decrement the inhibition flag, instead of just setting or
12360 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12362 Remove obsolete '#define static' cruft.
12363 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12364 This #undef was "temporary" in 2000; it is no longer needed
12365 now that '#define static' has gone away.
12366 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12367 (gray_bitmap_bits): Remove; no longer needed.
12368 All uses replaced with definiens.
12369 * xterm.c: Include "bitmaps/gray.xbm".
12371 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
12373 Clean up __executable_start, monstartup when --enable-profiling.
12374 The following changes affect the code only when profiling.
12375 * dispnew.c (__executable_start): Rename from safe_bcopy.
12376 Define only on platforms that need it.
12377 * emacs.c: Include <sys/gmon.h> when profiling.
12378 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12379 (__executable_start): Remove decl, since lisp.h does it now.
12380 (safe_bcopy): Remove decl; no longer has that name.
12381 (main): Coalesce #if into single bit of code, for simplicity.
12382 Cast pointers to uintptr_t, since standard libraries want integers
12384 * lisp.h (__executable_start): New decl.
12386 2012-05-31 Glenn Morris <rgm@gnu.org>
12388 * image.c (Fimagemagick_types): Doc fix.

12406 * lisp.h (Qdefun): Remove.
12407 * lread.c (read1): Tiny simplification.
12409 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
12411 Do not create empty overlays with the evaporate property (Bug#9642).
12412 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12413 Bug#9642, but explicitly check that the buffer the overlay would
12414 be moved to is live and rearrange lines to make sure that errors
12415 will not put the overlay in an inconsistent state.
12416 (Fdelete_overlay): Cosmetics.
12418 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12420 * w32term.c (my_bring_window_to_top): New function.
12421 (x_raise_frame): Use handle returned by DeferWindowPos, which
12422 could be different from the original one.
12423 Call my_bring_window_to_top instead of my_set_foreground_window.

12432 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12434 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12435 This avoids undefined behavior that might cause the eassert
12436 to not catch an out-of-range value.
12438 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12440 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
12441 Update dependencies.
12443 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12445 * bidi.c (bidi_mirror_char): Fix last change.
12447 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>

12452 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12454 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12455 Only r_alloc_inhibit_buffer_relocation needed to be added;
12456 the others were already declared.
12458 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12459 before checking whether it's out of range. Put the check inside
12461 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12463 2012-05-27 Ken Brown <kbrown@cornell.edu>
12465 * callproc.c (Fcall_process): Restore a line that was accidentally
12466 commented out in the 2011-02-13 change (bug#11547).
12468 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12470 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12471 defined on ralloc.c.
12473 * buffer.c [REL_ALLOC]: Remove prototypes of
12474 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12475 they are now on lisp.h.
12477 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12479 * search.c (search_buffer): Use it to inhibit relocation of buffer
12480 text while re_search_2 is doing its job, because re_search_2 is
12481 passed C pointers to buffer text. (Bug#11519)
12483 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12484 Update value to 24.
12486 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12487 state after an additional call to move_it_in_display_line_to, keep
12488 the values of it->max_ascent and it->max_descent found for the
12490 (pos_visible_p): Revert the comparison against bottom_y to what it
12491 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12494 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12496 Fix coding-related core dumps with gcc -ftrapv.
12497 The code was computing A - B, where A and B are pointers, and B is
12498 random garbage. This can lead to core dumps on platforms that
12499 have special pointer registers, and it also leads to core dumps on
12500 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12501 A - B only when B is initialized properly.
12502 * coding.c (coding_set_source, coding_set_destination): Return void.
12503 (coding_change_source, coding_change_destinations): New functions,
12504 with the old behaviors of coding_set_source and coding_set_destination.
12505 All callers that need an offset changed to use these new functions.
12507 2012-05-26 Glenn Morris <rgm@gnu.org>
12509 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12511 2012-05-26 Eli Zaretskii <eliz@gnu.org>

12514 * xdisp.c (draw_row_with_mouse_face):
12515 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12517 * w32console.c: Include window.h.
12518 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12520 (initialize_w32_display): Initialize mouse-highlight data.
12522 * w32inevt.c: Include termchar.h and window.h.
12523 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12524 moves, call note_mouse_highlight. If help_echo changed, call
12525 gen_help_event to produce help-echo message in the echo area.
12526 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12529 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12531 * lread.c (read1): Simplify slightly to avoid an overflow warning
12532 with GCC 4.7.0 on x86-64.
12534 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12536 * bidi.c (bidi_mirror_char): Revert last change: an int is
12537 definitely wide enough here.
12539 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12541 Fix integer width and related bugs (Bug#9874).

12548 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12549 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12551 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12552 (allocate_pseudovector):
12553 Use int, not EMACS_INT, where int is wide enough.
12554 (inhibit_garbage_collection, Fgarbage_collect):
12555 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12556 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12557 int might not be wide enough.
12558 (bidi_cache_search, bidi_cache_find, bidi_init_it)
12559 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
12560 (bidi_at_paragraph_end, bidi_find_paragraph_start)
12561 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
12562 (bidi_level_of_next_char, bidi_move_to_visually_next):
12563 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12564 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
12565 (Fkill_buffer, Fset_buffer_major_mode)
12566 (advance_to_char_boundary, Fbuffer_swap_text)
12567 (Fset_buffer_multibyte, overlays_at, overlays_in)
12568 (overlay_touches_p, struct sortvec, record_overlay_string)
12569 (overlay_strings, recenter_overlay_lists)
12570 (adjust_overlays_for_insert, adjust_overlays_for_delete)
12571 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)

12573 (Foverlay_recenter, last_overlay_modification_hooks_used)
12574 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12575 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12576 (validate_region): Omit unnecessary test for b <= e,
12577 since that's guaranteed by the previous test.
12578 (adjust_overlays_for_delete): Avoid pos + length overflow.
12579 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12580 (report_overlay_modification):
12581 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12582 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12583 Omit pointer cast, which isn't needed anyway, and doesn't work
12584 after the EMACS_INT -> ptrdiff_t change.
12585 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12586 * buffer.h: Adjust decls to match defn changes elsewhere.
12587 (struct buffer_text, struct buffer):
12588 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12589 Use EMACS_INT, not int, where int might not be wide enough.
12590 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12591 not int, to avoid needless 32-bit limit on 64-bit hosts.
12592 (exec_byte_code): Use tighter memory-full test, one that checks
12593 for alloca overflow. Don't compute the address of the object just
12594 before an array, as that's not portable. Use EMACS_INT, not
12595 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12596 * callint.c (Fcall_interactively):
12597 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12598 * callproc.c (call_process_kill, Fcall_process):
12599 Don't assume pid_t fits into an Emacs fixnum.

12608 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12609 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12610 (casify_object): Avoid integer overflow when overallocating buffer.
12611 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12612 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.

12614 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12615 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12616 integers are now checked earlier. All uses replaced with XINT.
12618 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12619 For CCL_MapSingle, check that content and value are in int range.
12620 (ccl_driver, Fregister_code_conversion_map):
12621 Check that Vcode_version_map_vector is a vector.
12622 (resolve_symbol_ccl_program): Check that vector header is in range.
12623 Always copy the vector, so that we can check its contents reliably
12624 now rather than having to recheck each instruction as it's being
12625 executed. Check that vector words fit in 'int'.
12626 (ccl_get_compiled_code, Fregister_ccl_program)
12627 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12628 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12629 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12630 contents are in range.
12631 (Fccl_execute_on_string): Check that status is in range.
12632 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12633 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

12641 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12642 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12643 avoid mishandling large integers.

12653 (Fdefine_charset_internal): Check ranges here, more carefully.
12654 Don't rely on undefined behavior with signed left shift overflow.
12655 Don't assume unsigned int fits into fixnum, or that fixnum fits
12656 into unsigned int. Don't require max_code to be a valid fixnum;
12657 that's not true for gb10830 4-byte on a 32-bit host. Allow
12658 invalid_code to be a cons, for the same reason. Require code_offset
12659 to be a character. Avoid int overflow if max_char is close
12661 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12662 this is intended anyway and avoids some undefined behavior.
12663 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12664 INDEX_TO_CODE_POINT, as that's what it expects.
12665 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12666 * charset.h (DECODE_CHAR): Return int, not unsigned;
12667 this is what was intended anyway, and it avoids undefined behavior.
12668 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12669 integer-overflow issues.
12670 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12671 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12672 where the argument is EMACS_INT, and this behavior is not intended.
12673 * chartab.c (Fmake_char_table, Fset_char_table_range)
12674 (uniprop_get_decoder, uniprop_get_encoder):
12675 Don't assume fixnum fits in int.
12676 * cmds.c (move_point): New function, that does the gist of
12677 Fforward_char and Fbackward_char, but does so while checking
12678 for integer overflow more accurately.
12679 (Fforward_char, Fbackward_char): Use it.
12680 (Fforward_line, Fend_of_line, internal_self_insert)
12681 (internal_self_insert):
12682 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13284 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):
13285 (handle_tool_bar_click):
13286 Use int, not unsigned, since we prefer signed and the signedness
13287 doesn't matter here.
13288 (get_next_display_element, next_element_from_display_vector):
13289 Use int, not EMACS_INT, when int is wide enough.
13290 (start_hourglass): Use duration_to_sec_usec to do proper
13291 overflow checking on durations.
13292 * xfaces.c (Fbitmap_spec_p):
13293 Check that fixnums are in proper range for system types.
13294 (compare_fonts_by_sort_order):
13295 Avoid mishandling comparisons due to subtraction overflow.
13296 (Fx_family_fonts, realize_basic_faces):
13297 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13299 Don't assume fixnum fits in int.
13300 Use SAFE_ALLOCA_LISP, not alloca.
13301 (merge_face_heights): Remove unnecessary cast to EMACS_INT.

13313 (Fx_change_window_property): Don't assume fixnums fit in int.
13314 * xfont.c (xfont_chars_supported):
13315 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

13323 (x_get_local_selection, x_reply_selection_request)
13324 (x_handle_selection_request, wait_for_property_change):
13325 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13326 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
13327 short is wide enough.
13328 (x_send_client_event): Don't assume fixnum fits in int.
13329 * xterm.c (x_x_to_emacs_modifiers):
13330 Don't assume EMACS_INT overflows nicely into int.
13331 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
13332 may come from Lisp.
13333 (handle_one_xevent): NATNUMP can eval its arg twice.
13334 (x_connection_closed):
13335 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
13336 * xterm.h: Adjust decls to match defn changes elsewhere.
13337 (struct scroll_bar): Use struct vectorlike_header
13338 rather than rolling our own approximation.
13339 (SCROLL_BAR_VEC_SIZE): Remove; not used.
13341 2012-05-25 Glenn Morris <rgm@gnu.org>
13343 * lisp.mk (lisp): Update for more files being compiled now.
13345 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
13347 * lread.c: Remove `read_pure' which makes no difference.
13348 (read_pure): Remove var.
13349 (unreadpure): Remove function.
13350 (readevalloop): Don't call read_list with -1 flag.
13351 (read1, read_vector): Don't test read_pure any more.
13352 (read_list): Simplify.
13354 * fileio.c, character.h: Minor style tweaks.
13356 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
13358 * window.h (clip_changed): Remove useless declaration.
13360 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
13362 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
13363 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
13365 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
13368 This directory predates autoconf and is no longer needed nowadays.
13369 Move its few remaining bits of functionality to where they're needed.
13370 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
13371 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
13372 * m/template.h: Remove.
13373 * Makefile.in (M_FILE): Remove. All uses removed.
13374 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
13375 * lisp.h (USE_LSB_TAG):
13376 * mem-limits.h (EXCEEDS_LISP_PTR):
13377 Use VAL_MAX, not VALBITS, in #if.
13378 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
13379 (EMACS_UINT): Define unconditionally now.
13380 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
13381 (BITS_PER_EMACS_INT): New constants, replacing
13382 what used to be in config.h, but not useful in #if.
13383 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
13384 define them any more.
13385 (VAL_MAX): New macro.
13387 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
13388 BITS_PER_EMACS_INT, in #if.
13389 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
13390 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
13391 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
13392 * s/ms-w32.h (DATA_START):
13393 Move here from removed file m/intel386.h.
13394 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
13395 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
13397 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
13399 Assume C89 or later.
13400 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
13401 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
13403 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

13409 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
13410 * xterm.c (input_signal_count): Assume volatile works.
13412 2012-05-21 Ken Brown <kbrown@cornell.edu>
13414 * xgselect.c (xg_select): Fix first argument in call to 'select'
13417 2012-05-20 Ken Brown <kbrown@cornell.edu>

13420 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
13422 2012-05-19 Ken Brown <kbrown@cornell.edu>
13424 * xfns.c (x_in_use): Remove `static' qualifier.
13425 * xterm.h (x_in_use): Declare.
13426 * xgselect.c: Include xterm.h.
13427 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
13428 and `display_arg' (bug#9754).
13430 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
13432 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
13434 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
13435 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
13437 2012-05-18 Eli Zaretskii <eliz@gnu.org>
13439 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
13441 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
13442 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
13444 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
13445 reference to image_cache->refcount.
13446 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
13448 2012-05-17 Juri Linkov <juri@jurta.org>
13450 * search.c (Fword_search_regexp, Fword_search_backward)
13451 (Fword_search_forward, Fword_search_backward_lax)
13452 (Fword_search_forward_lax): Move functions to isearch.el
13453 (bug#10145, bug#11381).
13455 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13457 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13459 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13461 * lread.c (init_obarray): Declare Qt and Qnil as special.
13463 2012-05-14 Glenn Morris <rgm@gnu.org>
13465 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13466 Put "libexec" before "bin", for the sake of init_callproc_1.
13468 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13470 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13472 * unexaix.c: Port to more-recent AIX compilers.
13473 (report_error, report_error_1, make_hdr, copy_sym)
13474 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13475 Make arguments const char *, not char *, to avoid violations of C
13476 standard and to fix some AIX warnings reported by Gilles Pion.
13478 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13480 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13481 already have overlays loaded.
13482 (handle_single_display_spec): Before returning without displaying
13483 fringe bitmap, synchronize the bidi iterator with the main display
13484 iterator, by calling iterate_out_of_display_property.
13485 (iterate_out_of_display_property): Detect buffer iteration by
13486 testing that it->string is a Lisp string.
13487 (get_next_display_element): When the current object is exhausted,
13488 and there's something on it->stack, call set_iterator_to_next to
13489 proceed with what's on the stack, instead of returning zero.
13490 (set_iterator_to_next): If called at the end of a Lisp string,
13491 proceed to consider_string_end without incrementing string
13492 position. Don't increment display vector index past the end of
13493 the display vector. (Bug#11417)
13494 (pos_visible_p): Don't report a position visible when move_it_to
13495 stopped at the last line of window, which happens to be scanned
13496 backwards by the bidi iteration. (Bug#11464)
13498 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13500 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13501 and right-margin display specs even if the spec is invalid or we
13502 are on a TTY, and thus unable to display on the fringes.
13503 That's because the text with the property will not be displayed anyway,
13504 so we need to signal to the caller that this is a "replacing"
13505 display spec. This fixes display when the spec is invalid or we
13508 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13510 * unexaix.c (make_hdr): Fix typo in prototype.
13511 This bug broke the build on AIX. Problem reported by Gilles Pion.
13513 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13515 * keyboard.c (kbd_buffer_get_event): Read special events also in
13516 batch mode. (Bug#11415)
13518 2012-05-12 Glenn Morris <rgm@gnu.org>
13520 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13522 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13524 * lisp.mk (lisp): Add newcomment.elc.
13526 2012-05-12 Glenn Morris <rgm@gnu.org>
13528 * Makefile.in (MKDIR_P): New, set by configure.
13529 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13531 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13533 Remove unused function hourglass_started.
13534 * dispextern.h (hourglass_started):
13535 * w32fns.c (hourglass_started):
13536 * xdisp.c (hourglass_started): Remove.
13538 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13540 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13541 Update dependencies.
13543 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13545 * xgselect.c (xg_select): Put maxfds+1 into a var.
13546 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13548 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13550 2012-05-10 Dave Abrahams <dave@boostpro.com>
13552 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13553 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13555 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13557 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13558 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13559 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13560 Initialize xd_registered_buses.
13562 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13564 Untag more efficiently if USE_LSB_TAG.
13565 This is based on a proposal by YAMAMOTO Mitsuharu in
13566 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13567 For an admittedly artificial (nth 8000 longlist) benchmark on
13568 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13569 Emacs's overall text size by 1%.
13570 * lisp.h (XUNTAG): New macro.
13571 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13572 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13573 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13574 * eval.c (Fautoload):
13575 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13576 * frame.h (XFRAME): Use XUNTAG.
13578 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13579 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13580 Remove unportable assumptions about print widths of types like
13582 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13583 intptr_t when converting between pointer and integer, to avoid GCC
13584 warnings about wrong width.
13586 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13588 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13589 stack for each reader_thread, instead of defaulting to 8MB
13590 determined by the linker. This avoids failures in creating
13591 subprocesses on Windows 7, see the discussion in this thread:
13592 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13594 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13596 Fix up display of the *Minibuf-0* buffer in the mini window.
13597 * keyboard.c (read_char): Don't clear the echo area if there's no
13599 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13600 contents of *Minibuf-0*) if there's no message displayed in its stead.
13602 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13604 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13607 2012-05-06 Chong Yidong <cyd@gnu.org>
13609 * lisp.mk (lisp): Update.
13611 2012-05-05 Jim Meyering <meyering@redhat.com>
13613 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13615 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13617 * data.c (PUT_ERROR): New macro.
13618 (syms_of_data): Use it. Add new error type `user-error'.
13619 * undo.c (user_error): New function.
13620 (Fprimitive_undo): Use it.
13621 * print.c (print_error_message): Adjust print style for `user-error'.
13622 * keyboard.c (user_error): New function.
13623 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13625 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13627 Do not limit current-time-string to years 1000..9999.
13628 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13629 (Fcurrent_time_string): Support any year that is supported by the
13630 underlying localtime representation. Don't use asctime, as it
13631 has undefined behavior for years outside the range -999..9999.
13633 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13635 Fix race conditions involving setenv, gmtime, localtime, asctime.
13636 Without this fix, interrupts could mess up code that uses these
13637 nonreentrant functions, since setting TZ invalidates existing
13638 tm_zone or tzname values, and since most of these functions return
13639 pointers to static storage.
13640 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13641 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13642 Grow the critical sections to include not just invoking
13643 localtime/gmtime, but also accessing these functions' results
13644 including their tm_zone values if any, and any related TZ setting.
13645 (format_time_string): Last arg is now struct tm *, not struct tm **,
13646 so that the struct tm is saved in the critical section.
13647 All callers changed. Simplify allocation of initial buffer, partly
13648 motivated by the fact that memory allocation needs to be outside
13649 the critical section.
13651 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13653 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13654 with RESET_INTERVAL.
13656 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13657 Remove duplicated buffer name initialization.
13659 2012-05-02 Jim Meyering <jim@meyering.net>
13661 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13663 * xfns.c (x_window): Use xstrdup (Bug#11375).
13665 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13667 * xdisp.c (pos_visible_p): If already at a newline from the
13668 display string before the 'while' loop, don't walk back the glyphs
13669 from it3.glyph_row. Solves assertion violation when the display
13670 string begins with a newline (egg.el). (Bug#11367)
13672 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13674 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13677 2012-05-01 Glenn Morris <rgm@gnu.org>
13679 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13680 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13681 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13682 All were removed before 23.1.
13684 * dispnew.c: Remove HAVE_LIBNCURSES test;
13685 it is always true on relevant platforms.
13687 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13688 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13690 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13692 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13694 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13695 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13698 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13700 Do not avoid creating empty evaporating overlays (Bug#9642).
13701 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13702 That is, do not delete an evaporating overlay if it becomes
13703 empty after its bounds are adjusted to fit within its buffer.
13704 This fix caused other problems, and I'm reverting it until we get
13705 to the bottom of them.
13707 2012-04-27 Chong Yidong <cyd@gnu.org>
13709 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13711 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13713 * xdisp.c (pos_visible_p): If the window start position is beyond
13714 ZV, start the display from buffer beginning. Prevents assertion
13715 violation in init_iterator when the minibuffer window is scrolled
13716 via the scroll bar.
13718 * window.c (window_scroll_pixel_based): Likewise.
13720 2012-04-27 Chong Yidong <cyd@gnu.org>

13726 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13727 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13729 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13731 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13732 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13734 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13736 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13737 display element, check also the underlying string or buffer
13738 character. (Bug#11341)
13740 * w32menu.c: Include w32heap.h.
13741 (add_menu_item): If the call to AppendMenuW (via
13742 unicode_append_menu) fails, disable Unicode menus only if we are
13743 running on Windows 9X/Me.
13745 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13747 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13748 (xgetint): Add missing shift for LSB tags.

13764 now a cons (bug#11311).
13766 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13768 Do not create empty overlays with the evaporate property (Bug#9642).
13769 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13770 if it becomes empty after its bounds are adjusted to fit within
13771 its buffer. Without this fix, in a nonempty buffer (let ((o
13772 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13773 yields an empty overlay that has the evaporate property, which is
13774 not supposed to happen.

13889 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13891 * sysdep.c [__FreeBSD__]: Minor cleanups.
13892 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13893 Use Emacs indenting style more consistently. Avoid some casts.
13894 Use 'double' consistently rather than mixing 'float' and 'double'.
13896 2012-04-21 Eduard Wiebe <usenet@pusto.de>
13898 * sysdep.c (list_system_processes, system_process_attributes):
13899 Add implementation for FreeBSD (Bug#5243).

13905 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13907 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13908 It is never used otherwise.
13910 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13912 * print.c (print_preprocess): Only check print_depth if print-circle

13919 * process.c (wait_reading_process_output): If EIO occurs on a pty,
13920 set the status to "failed" and ensure that sentinel is run.
13922 2012-04-20 Glenn Morris <rgm@gnu.org>
13924 * process.c (Fset_process_inherit_coding_system_flag)
13925 (Fset_process_query_on_exit_flag): Doc fix (mention return value).

13953 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
13954 -Wunused-result, -Wunused-variable. This should go away once
13955 the Emacs and Gnulib regex code is merged.

13975 New extern decls, to avoid calling undeclared functions.
13976 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13977 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
13978 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
13979 (NEED_MEM_INSERT): New macro.
13980 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13981 Remove one incorrect comment and fix another.

14017 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14018 * s/netbsd.h, s/sol2-6.h:
14019 Remove definition of GC_MARK_STACK, since the default now works.
14020 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

14048 2012-04-11 Daniel Colascione <dancol@dancol.org>
14050 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14051 against is gone. It's better to use vfork now so that when Cygwin
14052 gains a new, working vfork, we use it automatically (bug#10398).
14054 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14075 being loaded (bug#10424).
14077 2012-04-09 Glenn Morris <rgm@gnu.org>
14079 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14080 not just in the obarray, before snarfing them. (Bug#11036)

14095 (emacs_gnutls_read): Use new log functions,
14096 `gnutls_handshakes_tried' process member, and
14097 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14098 attempts per process (connection).
14100 2012-04-09 Chong Yidong <cyd@gnu.org>
14102 * eval.c (Fuser_variable_p, user_variable_p_eh)

14104 (Fdefvar): Caller changed.
14106 * callint.c (Finteractive, Fcall_interactively):
14107 * minibuf.c (Fread_variable): Callers changed.
14109 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14111 * xdisp.c (set_cursor_from_row): If the display string appears in
14112 the buffer at position that is closer to point than the position
14113 after the display string, display the cursor on the first glyph of
14114 the display string. Fixes cursor display when a 'display' text
14115 property immediately follows invisible text. (Bug#11094)
14117 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14119 composite.c: use 'double' consistently
14120 * composite.c (get_composition_id): Use 'double' consistently
14121 instead of converting 'float' to 'double' and vice versa; this is
14122 easier to understand and avoids a GCC warning.
14124 2012-04-09 Glenn Morris <rgm@gnu.org>
14126 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14127 preparation for dumping it with emacs. (Bug#4789)

14148 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14149 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14150 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14151 objects, as mark_maybe_pointer will catch them otherwise.
14152 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
14153 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

14171 [!WINDOWSNT]: New macros.
14172 (init_libxml2_functions, libxml2_loaded_p): New functions.
14173 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14174 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14175 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14176 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14178 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14179 Call init_libxml2_functions before calling libxml2 functions.
14180 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14182 * emacs.c: Don't include libxml/parser.h.
14183 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14184 xmlCleanupParser directly.
14186 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14188 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14190 * indent.c (Fvertical_motion): If there is a display string at
14191 point, use it.vpos to compute how many lines to backtrack after

14194 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14196 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14197 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14198 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14199 macros related to unification of CJK characters. For the details,
14200 see the discussion following the message here:
14201 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14203 2012-04-04 Chong Yidong <cyd@gnu.org>
14205 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14207 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14209 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
14210 instead of alloca. (Bug#11138)
14212 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>

14217 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14219 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14220 position we get to after a call to move_it_to fails the
14221 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14222 only if we wind up in a string from display property. (Bug#11063)
14224 * window.c (Fdelete_other_windows_internal): Invalidate the row
14225 and column information about mouse highlight, so that redisplay
14226 restores it after reallocating the glyph matrices. (Bug#7464)
14228 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14229 string comes from a `display' text property, use the buffer
14230 position of that property as if we actually saw that position in
14232 (move_it_by_lines): Remove the assertion that
14233 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14234 violated when there's a before-string at the beginning of a line.
14237 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14239 * xdisp.c (append_space_for_newline): If the default face was
14240 remapped, use the remapped face for the appended newline.
14241 (extend_face_to_end_of_line): Use the remapped default face for
14242 extending the face to the end of the line.
14243 (display_line): Call extend_face_to_end_of_line when the default
14244 face was remapped. (Bug#11068)
14246 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14248 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

14252 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
14254 2012-03-27 Glenn Morris <rgm@gnu.org>
14256 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
14259 2012-03-26 Kenichi Handa <handa@m17n.org>

14266 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14267 (command_loop_1): Use it; inhibit selection update for
14268 handle-select-window too (Bug#8996).
14270 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
14272 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14274 2012-03-25 Kenichi Handa <handa@m17n.org>
14276 * dispextern.h (struct glyph): Change the bit length of
14277 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14279 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14281 * s/ms-w32.h (tzname): Include time.h before redirecting to
14282 _tzname. Fixes the MSVC build. (Bug#9960)
14284 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
14286 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14289 * xterm.c (XTread_socket): Only modify handling_signal if
14290 !SYNC_INPUT. (Bug#11080)
14292 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14294 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14295 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14296 when fetching a multibyte character consumes more bytes than
14297 CHAR_BYTES returns, due to unification of CJK characters in
14298 string_char. (Bug#11073)
14300 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14302 * process.c (wait_reading_process_output): Handle pty disconnect
14303 by refraining from sending oneself a SIGCHLD (bug#10933).

14311 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14312 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14314 2012-03-21 Chong Yidong <cyd@gnu.org>
14316 * xfaces.c (Vface_remapping_alist): Doc fix.
14318 2012-03-20 Eli Zaretskii <eliz@gnu.org>
14320 * w32proc.c (Fw32_set_console_codepage)
14321 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

14326 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
14327 to reflect default non-nil value of redisplay-dont-pause.
14329 2012-03-19 Kenichi Handa <handa@m17n.org>
14331 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
14332 it fit in a valid range (Bug#11003).
14334 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14336 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14337 that is not from display property, accept the row as a "cursor
14338 row" if one of the string's character has a non-nil `cursor'
14339 property. Fixes cursor positioning when there are newlines in
14340 overlay strings, e.g. in icomplete.el. (Bug#11035)
14342 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14344 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14346 2012-03-12 Chong Yidong <cyd@gnu.org>
14348 * eval.c (inhibit_lisp_code): Rename from
14349 inhibit_window_configuration_change_hook; move from window.c.
14351 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14352 * window.c (run_window_configuration_change_hook)
14353 (syms_of_window): Callers changed.

14373 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14376 2012-03-03 Glenn Morris <rgm@gnu.org>
14378 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14380 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14382 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14383 position past the first glyph_row that ends at ZV. (Bug#10902)
14384 (redisplay_window, next_element_from_string): Fix typos in
14386 (redisplay_window): Pass to move_it_vertically the margin in
14387 pixels, not in screen lines.
14389 2012-03-02 Glenn Morris <rgm@gnu.org>
14391 * buffer.c (buffer-list-update-hook): Doc fix.
14393 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14395 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14396 push_it before setting up the iterator for the first overlay
14397 string, even if we have an empty string loaded.
14398 (next_overlay_string): If there's an empty string on the iterator
14399 stack, pop the stack. (Bug#10903)
14401 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14403 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14404 Suggested by Stefan Monnier in
14405 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14406 * alloc.c (widen_to_Lisp_Object): New static function.
14407 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14408 and widening them to Lisp_Objects. This would work even if
14409 USE_LSB_TAG is defined and wide integers are used, which might
14410 happen in a future version of Emacs.
14412 2012-02-25 Chong Yidong <cyd@gnu.org>
14414 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14417 * xselect.c (Fx_selection_exists_p): Doc fix.

14419 before saving to clipboard manager.
14421 2012-02-24 Chong Yidong <cyd@gnu.org>
14423 * keyboard.c (process_special_events): Handle all X selection
14424 requests in kbd_buffer, not just the next one (Bug#8869).
14426 2012-02-23 Chong Yidong <cyd@gnu.org>
14428 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14429 call when setting menu-bar-lines and tool-bar-lines parameters.
14430 (unwind_create_frame_1): New helper function.

14451 when computing $valmask.
14453 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14454 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14455 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14456 It's useless in that case, and it can cause problems on hosts
14457 that allocate halves of EMACS_INT values separately.
14458 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14459 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14460 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14461 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14462 it avoids undefined behavior on hosts where shifting right by more
14463 than the word width has undefined behavior.
14465 2012-02-19 Chong Yidong <cyd@gnu.org>
14467 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14468 (Funhandled_file_name_directory, Ffile_name_as_directory)
14469 (Fdirectory_file_name, Fexpand_file_name)

14485 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14487 2012-02-15 Chong Yidong <cyd@gnu.org>
14489 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14490 marked as special. Also, starting docstrings with * is obsolete.

14505 2012-02-12 Chong Yidong <cyd@gnu.org>
14507 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14508 as that creates a dangerous corner case.
14510 * window.c (Fdelete_window_internal): Invalidate the mouse
14511 highlight (Bug#9904).
14513 2012-02-12 Glenn Morris <rgm@gnu.org>

14516 (Fx_get_selection_internal, Fx_disown_selection_internal)
14517 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
14518 * nsselect.m (Fx_own_selection_internal)
14519 (Fx_disown_selection_internal, Fx_selection_exists_p)
14520 (Fx_selection_owner_p, Fx_get_selection_internal):
14521 Sync docs and argument specs with the xselect.c versions.
14523 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
14525 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.

14543 2012-02-07 Chong Yidong <cyd@gnu.org>
14545 * buffer.c (Fbuffer_local_variables)
14546 (buffer_lisp_local_variables): Handle unbound vars correctly;
14547 don't let Qunbound leak into Lisp.
14549 2012-02-07 Glenn Morris <rgm@gnu.org>
14551 * image.c (Fimagemagick_types): Doc fix.
14553 * image.c (imagemagick-render-type): Change it from a lisp object
14554 to an integer. Move the doc here from the lisp manual.
14555 Treat all values not equal to 0 the same.
14557 2012-02-06 Chong Yidong <cyd@gnu.org>
14559 * doc.c (store_function_docstring): Avoid applying docstring of

14578 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
14579 after rounding frame sizes. (Bug#9723)
14581 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14583 * keyboard.c (adjust_point_for_property): Don't position point
14584 before BEGV. (Bug#10696)
14586 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14588 Handle overflow when computing char display width (Bug#9496).
14589 * character.c (char_width): Return EMACS_INT, not int.
14590 (char_width, c_string_width): Check for overflow when
14591 computing the width; this is possible now that individual
14592 characters can have unbounded width. Problem introduced
14593 by merge from Emacs 23 on 2012-01-19.
14595 2012-02-02 Michael Albinus <michael.albinus@gmx.de>

15128 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
15129 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
15130 this macro definition.
15132 * s/ms-w32.h (tzname): Redirect to _tzname for all values of

15157 * xdisp.c (redisplay_window): If cursor row is not fully visible
15158 after recentering, and scroll-conservatively is set to a large
15159 number, scroll window by a few more lines to make the cursor fully
15160 visible and out of scroll-margin. (Bug#10105)
15161 (start_display): Don't move to the next line if the display should
15162 start at a newline that is part of a display vector or an overlay
15163 string. (Bug#10119)

15246 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15247 is set, removing the need for VIRT_ADDRESS_VARIES.
15248 (PURE_P): Use a more-efficient implementation that needs just one
15249 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
15250 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
15251 to 4 (xorl, subq, cmpq, setbe).
15252 * alloc.c (pure): Always extern now, since that's the
15253 VIRT_ADDR_VARIES behavior.

15255 consistency with the new puresize.h.
15256 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
15257 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

15263 (erase_phys_cursor, update_window_cursor, show_mouse_face)
15264 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
15265 behave as if the cursor position were at the window margin.
15267 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15268 and the cursor position is out of bounds, behave as if the cursor
15269 position were at the window margin. (Bug#10075)
15271 2011-11-18 Chong Yidong <cyd@gnu.org>
15273 * window.c (Fwindow_combination_limit): Make first argument

15292 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
15294 * xdisp.c (row_hash): New function, body extracted from
15295 compute_line_metrics.
15296 (compute_line_metrics): Call row_hash, instead of computing the
15299 * dispnew.c (verify_row_hash): Call row_hash for computing the
15300 hash code of a row, instead of duplicating code from xdisp.c.
15302 * dispextern.h (row_hash): Add prototype.
15304 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
15306 * frame.c (delete_frame): Don't delete the terminal when the last

15332 (Fsplit_window_internal, saved_window)
15333 (Fset_window_configuration, save_window_save): Rename all
15334 occurrences of window_nest to window_combination_limit.

15340 2011-11-14 Eli Zaretskii <eliz@gnu.org>
15342 * xdisp.c (display_line): Move the call to
15343 highlight_trailing_whitespace before the call to
15344 compute_line_metrics, since the latter needs to see the final
15345 faces of all the glyphs to compute ROW's hash value.
15346 Fixes assertion violations in row_equal_p. (Bug#10035)
15348 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
15350 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
15351 just return (bug#10044).
15353 2011-11-12 Eli Zaretskii <eliz@gnu.org>
15355 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
15356 with user-defined heap size. Bump the default size of the temacs
15357 heap to 27MB, to avoid memory warning when running temacs.
15358 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
15360 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15361 current_matrix and desired_matrix. (Bug#9990)
15362 (verify_row_hash) [XASSERTS]: New function.
15363 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify

15396 avoid a crash (bug#9496).
15398 2011-11-09 Chong Yidong <cyd@gnu.org>
15400 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

15407 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
15409 Avoid some portability problems by eschewing 'extern inline' functions.
15410 The trivial performance wins aren't worth the portability hassles; see
15411 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15413 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
15414 (window_box_width, window_box_left, window_box_left_offset)
15415 (window_box_right, window_box_right_offset): Undo previous change,
15416 by removing the "extern"s.
15417 * intervals.c (adjust_intervals_for_insertion)
15418 (adjust_intervals_for_deletion): Undo previous change,
15419 making these static again.
15420 (offset_intervals, temp_set_point_both, temp_set_point)
15421 (copy_intervals_to_string): No longer inline.
15422 * xdisp.c (window_text_bottom_y, window_box_width)

15462 This is also needed for porting to any host where GC_MARK_STACK is
15463 not GC_MAKE_GCPROS_NOOPS.
15464 (which_symbols): Use it.
15466 2011-11-07 Kenichi Handa <handa@m17n.org>

15479 * xmenu.c (cleanup_widget_value_tree): New function.
15480 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15481 calling free_menubar_widget_value_tree directly (Bug#9830).
15483 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
15485 Fix some portability problems with 'inline'.

15487 (window_box_width, window_box_left, window_box_left_offset)
15488 (window_box_right, window_box_right_offset): Declare extern.
15489 Otherwise, these inline functions do not conform to C99 and
15490 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15491 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15492 * intervals.c (adjust_intervals_for_insertion)
15493 (adjust_intervals_for_deletion): Now extern, because otherwise the
15494 extern inline functions 'offset_intervals' couldn't refer to it.
15495 (static_offset_intervals): Remove.
15496 (offset_intervals): Rewrite using the old contents of
15497 static_offset_intervals. The old version didn't conform to C99
15498 because an extern inline function contained a reference to an
15499 identifier with static linkage.

15606 previous/next-single-property-change returns nil, treat that as
15607 the beginning or the end of the buffer. (Bug#9955)
15609 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
15611 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
15612 label is not null (Bug#9951).
15613 (xg_tool_item_stale_p): Handle the fact that wimage and/or wlbl

15645 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
15646 past the beginning of the current glyph matrix.
15648 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
15650 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
15651 (x_error_handler): Ignore BadMatch for X_SetInputFocus for

15694 2011-10-29 Glenn Morris <rgm@gnu.org>
15696 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
15697 Not clear what it was for, and it causes various bugs. (Bug#9839)
15699 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15701 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
15702 possible random value that matches one of those tested as
15703 condition to clear the mouse face.
15705 2011-10-28 Chong Yidong <cyd@gnu.org>

15721 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15723 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
15724 <oslsachem@gmail.com> for helping to debug this.
15726 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

15732 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
15734 (w32font_open_internal, compute_metrics):
15735 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15736 instead of calling the "wide" APIs directly.
15738 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15740 * w32.h (syms_of_w32font): Add prototype.
15742 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15744 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
15745 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
15746 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15747 (Fmove_to_window_line): Doc fix.
15749 2011-10-27 Chong Yidong <cyd@gnu.org>
15751 * process.c (make_process): Set gnutls_state to NULL.
15753 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15754 non-NULL, regardless of GNUTLS_INITSTAGE.
15755 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
15756 an error. Set process slots as soon as we allocate them.
15758 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
15760 2011-10-27 Chong Yidong <cyd@gnu.org>
15762 * gnutls.c (emacs_gnutls_deinit): New function.

15767 (deactivate_process): Call emacs_gnutls_deinit.
15769 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15771 * image.c (x_create_x_image_and_pixmap):
15772 * w32.c (sys_rename, w32_delayed_load):
15773 * w32font.c (fill_in_logfont):

15779 extracted from Fw32_default_color_map.
15780 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
15782 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15784 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
15786 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
15788 * keyboard.c (test_undefined): New function (bug#9751).
15789 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
15791 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15793 * sysdep.c (init_sys_modes): Fix the check for the controlling
15794 terminal (Bug#6649).
15796 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15798 * dispextern.h (struct bidi_it): New member next_en_type.
15800 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15801 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15802 current character, check also for next_en_type being WEAK_EN.
15803 (bidi_resolve_weak): Don't enter the expensive loop if the current
15804 position is before next_en_pos. Record the bidi type of the first
15805 non-ET, non-BN character we find, in addition to its position.
15806 (bidi_level_of_next_char): Invalidate next_en_type when
15807 next_en_pos is over-stepped.
15809 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15811 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15812 * editfns.c: Rewrite current-time-zone so that it invokes
15813 the equivalent of (format-time-string "%Z") to get the time zone name.
15814 This fixes a bug when the time zone name contains characters that
15815 need converting from the system time locale to Emacs internal format.
15816 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15817 that patch fixed format-time-string to do the conversion, but
15818 I forgot to fix current-time-zone.
15819 (format_time_string): New function, containing most of
15820 what Fformat_time_string used to contain.
15821 (Fformat_time_string): Rewrite in terms of format_time_string.
15822 This doesn't change this function's behavior.
15823 (current-time-zone): Rewrite to use format_time_string.
15824 This fixes the bug reported by Michael Schierl in
15825 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15826 Jason Rumney's 2007-06-07 change worked around this bug, but
15828 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15830 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15832 * xdisp.c (start_display): If the character at POS is displayed
15833 via a display vector, reset IT->current.dpvec_index to zero.
15834 (try_window_reusing_current_matrix): If a line ends in a display
15835 vector or the next line starts in a display vector, continue
15836 redrawing the window even though the character position of
15837 start_row was reached.
15840 2011-10-18 Chong Yidong <cyd@gnu.org>
15842 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15843 with nobreak-char-display too.
15845 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15847 Fix part 3 of bug#9771.
15848 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15849 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15850 non-neutral characters if the current character is a paragraph
15851 separator (a.k.a. Newline). This avoids running the same
15852 expensive loop twice, once when we consume the preceding newline
15853 and the other time when the line actually needs to be displayed.
15854 Avoid the loop when we see neutrals on the base embedding level
15855 following a character whose directionality is the same as the
15856 paragraph's. This avoids running the expensive loop when a line
15857 ends in a long sequence of neutrals, like control characters.
15858 Add assertion against STRONG_AL type. Slightly rearrange code
15859 that determines the type of a neutral given the first non-neutral
15861 (bidi_level_of_next_char): Set next_en_pos to zero when
15862 invalidating its info.
15864 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15866 * xdisp.c (push_display_prop): Determine whether to record string
15867 or buffer position by IT->string, not by IT->method. Allow
15868 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15869 (move_it_vertically_backward): Don't look for character position
15870 immediately after the newline when in a continuation line.
15873 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15875 * window.c (coordinates_in_window): Rewrite and delabelize
15876 vertical border check. (Bug#5357) (Bug#9618)
15878 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15880 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15881 errors in XSetWindowBorder (bug#9310).
15883 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15885 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15886 avoid crash when xmalloc overrun checking is enabled.
15888 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15890 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15891 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15892 cursor motion with <left> and <right> arrow keys.
15894 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15895 some callers set that themselves.
15897 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15899 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15900 display string and the previous row comes from the same string and
15901 is empty. (Bug#9739) (Bug#9738)
15903 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15905 * doc.c (get_doc_string): Encode file name (bug#9735).
15907 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15909 * bidi.c (bidi_level_of_next_char):
15910 * xdisp.c (get_visually_first_element): Remove old incorrect
15911 comments regarding the Unicode Line Separator character.
15913 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15915 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15917 * alloc.c (Fgc_status): Do not access beyond zombies array
15918 boundary if nzombies > MAX_ZOMBIES.
15919 * alloc.c (dump_zombies): Add missing format specifier.
15921 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15923 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15924 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15926 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15927 Some packages use them to denote characters with modifiers.
15929 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15931 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15932 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15933 matching a pp-number. Rename parameter var to var1.
15935 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15937 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15939 2011-10-08 Glenn Morris <rgm@gnu.org>
15941 * callint.c (Fcall_interactively): Give a more explicit error for the
15942 'c' case with a non-character input. (Bug#8479)
15944 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15946 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15948 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15949 lines that are hscrolled on the left.
15951 * dispnew.c (buffer_posn_from_coords): Account for a possible
15952 presence of header-line. (Bug#4426)
15954 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15956 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15957 Don't advertise functionality which we discourage or doesn't work.
15959 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15961 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15962 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15963 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15964 this makes Emacs dump core during garbage collection on rare
15965 occasions. sizeof is obviously inferior to offsetof here, so
15966 stick with offsetof.
15967 (GC_POINTER_ALIGNMENT): New macro.
15968 (mark_memory): Omit 3rd (offset) arg; caller changed.
15969 Don't assume EMACS_INT alignment is the same as pointer alignment.
15971 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15973 * keyboard.c (read_key_sequence_remapped): New var.
15974 (read_key_sequence): Compute remapping in the right buffer.
15975 (command_loop_1): Use read_key_sequence's remapping directly.
15977 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15979 * dired.c (file_name_completion): Don't expand file name.
15980 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15981 before checking file name handler.
15983 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15984 they've been requested explicitly (bug#9591).
15986 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15988 * keymap.c (Fsingle_key_description): Use make_specified_string
15989 instead of build_string to build string from push_key_description.
15992 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15994 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15995 This fixes a Y2038 bug on 64-bit hosts.
15996 * buffer.c (reset_buffer):
15997 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15998 (Fclear_buffer_auto_save_failure):
15999 Use 0, not -1, to represent an unset failure time, since time_t
16000 might not be signed.
16002 Remove dependency on glibc malloc internals.
16003 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16004 Move back here from lisp.h, but with their new implementations.
16005 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16006 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16007 * charset.c (charset_table_init): New static var.
16008 (syms_of_charset): Use it instead of xmalloc. This removes a
16009 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16010 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16011 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16012 Move back to alloc.c.
16013 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16014 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16016 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16018 * nsterm.m (windowDidResize): Call x_set_window_size only when
16019 ns_in_resize is true. Otherwise set pixelwidth/height and
16020 call change_frame_size (Bug#9628).
16022 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16024 Port --enable-checking=all to Fedora 14 x86-64.
16025 * charset.c (syms_of_charset): Also account for glibc malloc's
16026 internal overhead when calculating the initial malloc maximum.
16028 Port --enable-checking=all to Fedora 14 x86.
16029 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16031 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16032 (overrun_check_realloc, overrun_check_free):
16033 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16034 That way, xmalloc returns a properly-aligned pointer even if
16035 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16036 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16037 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16038 into account when calculating the initial malloc maximum.
16039 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16040 Move here from alloc.c, so that charset.c can use it too.
16041 Properly align; the old code wasn't right for common 32-bit hosts
16042 when configured with --enable-checking=all.
16043 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16044 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16046 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16048 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16051 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16053 * xdisp.c (compute_display_string_end): If there's no display
16054 string at CHARPOS, return -1.
16056 * bidi.c (bidi_fetch_char): When compute_display_string_end
16057 returns a negative value, treat the character as a normal
16058 character not covered by a display string. (Bug#9624)
16060 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16062 * lread.c (Fread_from_string): Fix typo in docstring.
16064 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16066 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16067 newline, reseat the iterator instead of bidi-iterating there one
16068 character at a time. (Bug#9610)
16069 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16070 TO_CHARPOS if the bidi iterator is at base embedding level.
16072 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16074 * lread.c (readevalloop): Use correct code for NBSP.
16075 (read1): Likewise. (Bug#9608)
16077 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16079 * dbusbind.c (Fdbus_register_signal): When service is not
16080 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16082 2011-09-25 Glenn Morris <rgm@gnu.org>
16084 * buffer.c (truncate-lines): Doc fix.
16086 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16088 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16089 (Fset_window_next_buffers): Doc fix.
16091 2011-09-24 Glenn Morris <rgm@gnu.org>
16093 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16095 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16097 Fix minor problems found by static checking.
16098 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16099 * indent.c (Fvertical_motion): Fix == vs = typo.
16101 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16103 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16104 Default value is now t. Doc fix.
16106 * indent.c (Fvertical_motion): Compute and apply the overshoot
16107 logic when moving up, not only when moving down. Fix the
16108 confusing name and values of the it_overshoot_expected variable;
16109 logic changes accordingly. (Bug#9254) (Bug#9549)
16111 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16112 CHARPOS is covered by a display string which includes newlines.
16113 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16114 is covered by a display string with embedded newlines.
16116 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16118 * dbusbind.c (Fdbus_register_signal): Add match rule to
16119 Vdbus_registered_objects_table. (Bug#9581)
16120 (Fdbus_register_method, Vdbus_registered_objects_table):
16123 2011-09-24 Jim Meyering <meyering@redhat.com>
16125 do not ignore write error for any output size
16126 The previous change was incomplete.
16127 While it makes emacs --batch detect the vast majority of stdout
16128 write failures, errors were still ignored whenever the output size is
16129 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16130 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16131 && echo FAIL: ignored write error
16132 FAIL: ignored write error
16133 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16134 && echo FAIL: ignored write error
16135 FAIL: ignored write error
16136 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16138 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16140 * emacs.c (Fkill_emacs): In noninteractive mode exit
16141 non-successfully if a write error occurred on stdout. (Bug#9574)
16143 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16145 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16148 * dispextern.h (struct it): Update the comment documenting what
16151 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16153 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16154 a display string, extend search for cursor position to end of row.
16155 (find_row_edges): If the row ends in a newline from a display
16156 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16157 Handle the case of a display string with multiple newlines.
16158 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16159 non-empty line. Fixes confusing cursor motion with arrow keys at
16160 the beginning of a line that starts with whitespace.
16162 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16164 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16167 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16169 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16170 boolean (Bug#9154).
16172 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16174 * xdisp.c (display_line): Record maximum and minimum buffer
16175 positions even if no glyphs were produced (e.g., by a zero-width
16176 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16177 buffer positions that will be removed from the glyph row because
16179 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16180 column is beyond frame width: don't subtract 1 "pixel" when
16181 computing width of the stretch.
16182 (reseat_at_next_visible_line_start): Undo the change made on
16183 2011-09-17 that saved paragraph information and restored it after
16184 the call to `reseat'. (Bug#9545)
16186 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16188 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16189 and turn window cursor on if cleared (Bug#9415).
16191 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16193 * search.c (boyer_moore): Take unibyte characters from pattern
16194 literally. (Bug#9458)
16196 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16198 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16200 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16202 Fix minor problem found by static checking.
16203 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16204 initialized, to pacify gcc -Wuninitialized.
16206 * fileio.c: Report proper errno when syscall falls.
16207 (Finsert_file_contents): Save and restore errno,
16208 so that report_file_error outputs the correct diagnostic.
16209 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16211 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16213 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16215 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16217 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16218 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16220 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16222 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16223 about the current paragraph and restore it after the call to reseat.
16225 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16226 (bidi_find_paragraph_start): Search back for paragraph beginning
16227 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16228 (bidi_move_to_visually_next): Only trigger paragraph-related
16229 computations when the last character is a newline or at EOB, not
16230 just any NEUTRAL_B. (Bug#9470)
16232 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16233 truncated lines if point is covered by a display string. (Bug#9524)
16235 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16237 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16238 (cons_to_x_long): New function.
16239 (lisp_data_to_selection_data): Use it. Correct the test for
16240 short-versus-long data; it was negated. Break out of vector
16241 loop, for efficiency, when a long datum is discovered.
16243 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16245 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16247 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16249 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16250 GCC PR/17406) by declaring this function with external scope.
16252 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16254 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16255 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16257 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16259 * editfns.c (Fformat): Correctly handle text properties on "%%".

16267 * xdisp.c (get_next_display_element)
16268 (fill_composite_glyph_string): Add comments about special meaning
16269 of TAB characters in a composition.
16271 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16273 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16274 This occurs when processing a multibyte format.
16275 Problem reported by Wolfgang Jenker.
16277 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16279 * xdisp.c (try_cursor_movement): Only check for exact match if
16280 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16282 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16284 Remove unused external symbols.
16285 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16286 * xdisp.c (calc_pixel_width_or_height): Now static.
16287 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16288 * indent.c (check_display_width):
16289 * w32term.c: Fix comment to match code.
16290 * xterm.c, xterm.h (x_catching_errors): Remove.
16292 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16294 * xselect.c: Use signed conversions more consistently (Bug#9498).
16295 (selection_data_to_lisp_data): Assume incoming selection data are
16296 signed integers, not unsigned. This is to be consistent with
16297 outgoing selection data, which was modified to use signed integers
16298 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16299 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16300 expects long, not unsigned long.
16302 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16304 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16305 computation of loop end. Reported by Johan Bockgård
16308 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16310 * frame.c (Fother_visible_frames_p): Function deleted.
16312 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16314 * indent.c (compute_motion): Process display vector front to back
16315 rather than the other way around. (Bug#2496)
16317 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16319 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16321 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16323 * minibuf.c (Fread_from_minibuffer): Doc fix.
16325 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16327 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16328 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16330 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16332 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16333 value for non-existent files.
16335 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16337 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16338 set its "size" to -1. This will set the modtime_size field of
16339 the corresponding buffer to -1, which is what
16340 verify-visited-file-modtime expects for files that do not exist.
16343 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16345 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16347 * lisp.h: ... from here. push_key_description is no longer
16348 defined in keyboard.c, so its declaration should not be in
16349 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16350 logically belongs with push_key_description.
16352 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16354 * buffer.h: Include <sys/types.h> instead of <time.h>.
16355 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16356 Problem reported by Herbert J. Skuhra.
16358 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16360 * xml.c (parse_region): Make the parsing work for
16361 non-comment-starting XML files again (bug#9144).
16363 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16365 * image.c (gif_load): Fix calculation of bottom and right corner.
16368 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16370 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16371 redisplay in small windows.
16373 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16375 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16377 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16379 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16380 Operate on live windows only.
16382 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16384 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16386 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16388 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16389 only under bidi iteration.
16391 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16393 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16395 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16397 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16398 Without this fix, the command to link temacs failed due to an
16399 undefined symbol __builtin_isnan. This is because
16400 /usr/include/iso/math_c99.h #defines isnan(x) to
16401 __builtin_isnan(x), but the bundled gcc, which identifies itself
16402 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16404 * floatfns.c (isnan): #undef, and then #define to a clone of
16406 (Fisnan): Always define, since it's always available now.
16407 (syms_of_floatfns): Always define isnan at the Lisp level.
16409 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16411 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16413 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16415 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16416 The previous code assumed that file offsets (off_t values) fit in
16417 EMACS_INT variables, which is not true on typical 32-bit hosts.
16418 The code messed up by falsely reporting buffer overflow in cases
16419 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16420 when "big" contains more than 2**29 bytes, even though this
16421 inserts just one byte and does not overflow the buffer.
16422 (Finsert_file_contents): Store file offsets as off_t
16423 values, not as EMACS_INT values. Check for overflow when
16424 converting between EMACS_INT and off_t. When checking for
16425 buffer overflow or for overlap, take the offsets into account.
16426 Don't use EMACS_INT for small values where int suffices.
16427 When checking for overlap, fix a typo: ZV was used where
16428 ZV_BYTE was intended.
16429 (Fwrite_region): Don't assume off_t fits into 'long'.
16430 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16432 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16434 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16436 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16438 sprintf-related integer and memory overflow issues (Bug#9412).
16440 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16441 (esprintf, exprintf, evxprintf): New functions.
16442 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16443 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16444 (modify_event_symbol): Do not assume that the length of
16445 name_alist_or_stem is safe to alloca and fits in int.
16446 (Fexecute_extended_command): Likewise for function name and binding.
16447 (Frecursion_depth): Wrap around reliably on integer overflow.
16448 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16449 since some callers pass EMACS_INT values.
16450 (Fsingle_key_description): Don't crash if symbol name contains more
16451 than MAX_ALLOCA bytes.
16452 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16453 (get_minibuffer): Arg is now EMACS_INT, not int.
16454 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16455 (esprintf, exprintf, evxprintf): New decls.
16456 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16458 * dbusbind.c (signature_cat): New function.
16459 (xd_signature, Fdbus_register_signal):
16460 Do not overrun buffer; instead, report string overflow.
16462 * dispnew.c (add_window_display_history): Don't overrun buffer.
16463 Truncate instead; this is OK since it's just a log.
16465 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16466 even if the time zone offset is outlandishly large.
16467 Don't mishandle offset == INT_MIN.
16469 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16470 when creating daemon; the previous buffer-overflow check was incorrect.
16472 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16473 which has the guts of the old verror function.
16475 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16476 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16478 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16479 (font_unparse_xlfd): Don't blindly alloca long strings.
16480 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16481 fits in int, when using sprintf. Use single snprintf to count
16482 length of string rather than counting it via multiple sprintfs;
16483 that's simpler and more reliable.
16484 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16485 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16486 sprintf, in case result does not fit in int.
16488 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16489 (fontset_from_font): Print it.
16491 * frame.c (tty_frame_count): Now printmax_t, not int.
16492 (make_terminal_frame, set_term_frame_name): Print it.
16493 (x_report_frame_params): In X, window IDs are unsigned long,
16494 not signed long, so print them as unsigned.
16495 (validate_x_resource_name): Check for implausibly long names,
16496 and don't assume name length fits in 'int'.
16497 (x_get_resource_string): Don't blindly alloca invocation name;
16498 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16501 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16502 (xg_check_special_colors, xg_set_geometry):
16503 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16505 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16506 Use esprintf, not sprintf, in case result does not fit in int.
16508 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16509 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16510 it as a large positive number.
16511 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16512 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16514 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16515 in case result does not fit in int.
16517 * print.c (float_to_string): Detect width overflow more reliably.
16518 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16519 buffer overrun. Don't assume list length fits in 'int'. Treat
16520 print length of 0 as 0, not as infinity; to be consistent with other
16521 uses of print length in this function. Don't overflow print length
16522 index. Don't assume hash table size fits in 'long', or that
16523 vectorlike size fits in 'unsigned long'.
16525 * process.c (make_process): Use printmax_t, not int, to format
16526 process-name gensyms.
16528 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16530 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16531 to avoid potential buffer overrun.
16533 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16534 if X resource line is longer than 512 bytes.
16536 * xfns.c (x_window): Make sprintf buffer a bit bigger
16537 to avoid potential buffer overrun.
16539 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16541 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16543 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16545 Integer overflow fixes for scrolling, etc.
16546 Without these, Emacs silently mishandles large integers sometimes.
16547 For example, "C-u 4294967297 M-x recenter" was treated as if
16548 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16550 * xdisp.c (try_window_id): Check Emacs fixnum range before
16551 converting to 'int'.
16553 * window.c (window_scroll_line_based, Frecenter):
16554 Check that an Emacs fixnum is in range before assigning it to 'int'.
16555 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16556 values converted from Emacs fixnums.
16557 (Frecenter): Don't wrap around a line count if it is out of 'int'
16558 range; instead, treat it as an extreme value.
16559 (Fset_window_configuration, compare_window_configurations):
16560 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16562 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16563 that can exceed INT_MAX. Check that EMACS_INT value is in range
16564 before assigning it to the (possibly-narrower) index.
16565 (match_limit): Don't assume that a fixnum can fit in 'int'.
16567 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16570 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16571 (Fvertical_motion): Don't wrap around LINES values that don't fit
16572 in 'int'. Instead, treat them as extreme values. This is good
16573 enough for windows, which can't have more than INT_MAX lines anyway.
16575 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16577 * Require libxml/parser.h to avoid compilation warning.
16579 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16581 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16582 since this reportedly can destroy thread storage.
16584 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16586 * syntax.c (find_defun_start): Update all cache variables if
16587 exiting early (Bug#9401).
16589 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16591 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16593 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16594 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16595 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16597 * term.c (tty_append_glyph): New function.
16598 (produce_stretch_glyph): Static function and its prototype deleted.
16600 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16603 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16605 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16606 when checking :margin (Bug#9390).
16607 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16608 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16609 so that the name doesn't mislead. All uses changed.
16611 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16613 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16616 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16618 * xdisp.c (move_it_to): Don't bail out early when reaching
16619 position beyond to_charpos, if we are scanning backwards.
16620 (move_it_vertically_backward): When DY == 0, make sure we get to
16621 the first character in the line after the newline.
16623 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16625 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16626 (ccl_driver): Do not generate an out-of-range pointer.
16627 (Fccl_execute_on_string): Remove unnecessary check for
16628 integer overflow, noted by Stefan Monnier in
16629 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16630 Remove a FIXME that didn't need fixing.
16631 Simplify the newly-introduced buffer reallocation code.
16633 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16635 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16637 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16639 Integer and memory overflow issues (Bug#9196).
16641 * doc.c (get_doc_string): Rework so that
16642 get_doc_string_buffer_size is the actual buffer size, rather than
16643 being 1 less than the actual buffer size; this makes xpalloc more
16646 * image.c (x_allocate_bitmap_record, cache_image):
16647 * xselect.c (Fx_register_dnd_atom):
16648 Simplify previous changes by using xpalloc.
16650 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16651 since either will do and ptrdiff_t is convenient with xpalloc.
16653 * charset.c (charset_table_size)
16654 (struct charset_sort_data.priority): Now ptrdiff_t.
16655 (charset_compare): Don't overflow if priorities differ greatly.
16656 (Fsort_charsets): Don't assume list length fits in int.
16657 Check for size-calculation overflow when allocating sort data.
16658 (syms_of_charset): Allocate an initial charset table that is
16659 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16661 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16663 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16664 The actual value is always <= INT_MAX, and leaving it unsigned made
16665 overflow checking harder.
16667 * dispextern.h (struct glyph_matrix.rows_allocated)
16668 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16669 with xpalloc. The values are still always <= INT_MAX.
16671 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16673 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16674 (SAFE_NALLOCA): New macro.
16676 * region-cache.c (struct boundary.pos, find_cache_boundary)
16677 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16678 (set_cache_region, invalidate_region_cache)
16679 (revalidate_region_cache, know_region_cache, region_cache_forward)
16680 (region_cache_backward, pp_cache):
16681 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16682 so that ptrdiff_t * can be passed to xpalloc.
16683 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16684 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16685 (pp_cache): Don't assume cache_len fits in int.
16686 * region-cache.h: Adjust extern decls to match.
16688 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16689 EMACS_INT, since either will do, for xpalloc.
16691 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16692 (xnmalloc, xnrealloc, xpalloc): New functions.
16694 * bidi.c (bidi_shelve_header_size): New constant.
16695 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16696 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16698 * bidi.c (bidi_cache_shrink):
16699 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16701 Don't update size of array until after memory allocation succeeds,
16702 because xmalloc/xrealloc may not return.
16703 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16704 now that we have proper integer overflow checking.
16705 (record_overlay_string, overlay_strings): Catch overflows when
16706 calculating size of overlay_str_buf.
16708 * callproc.c (Fcall_process): Check for size overflow when
16709 calculating size of args2.
16710 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16711 Normally we prefer signed values, but sticking with ptrdiff_t would
16712 require adding more-complicated checks.
16714 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16715 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16716 Redo buffer-overflow calculations to avoid integer overflow.
16717 Add a FIXME comment where memory seems to be over-allocated.
16719 * character.c (Fstring): Check for size-calculation overflow.
16721 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16722 unnecessary integer overflow. Check for size overflow.
16723 (encode_coding_object): Don't update size until xmalloc succeeds.
16725 * composite.c (get_composition_id): Check for overflow in glyph
16726 length calculations.
16728 Integer and memory overflow fixes for display code.
16729 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16730 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16731 (scrolling_window): Check for overflow in size calculations.

16739 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16740 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

16743 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16744 (get_doc_string): Check for size calculation overflow.
16745 Don't update size until allocation succeeds.
16746 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16747 EMACS_INT, where ptrdiff_t will do.
16748 (Fsubstitute_command_keys): Check for string overflow.
16750 * editfns.c (set_time_zone_rule): Don't assume environment length
16752 (message_length): Now ptrdiff_t, not int.
16753 (Fmessage_box): Don't update size until allocation succeeds.
16754 Don't assume message length fits in int.
16755 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16757 * emacs.c (main): Do not reallocate argv, since there is a null at
16758 the end that can be overwritten, and this way there's no need to
16759 worry about size-calculation overflow.
16760 (sort_args): Check for size-calculation overflow.
16762 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16764 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16766 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16767 (x_set_scroll_bar_width, x_figure_window_size):
16768 Check for integer overflow.
16769 (x_set_alpha): Do not assume XINT fits in int.
16771 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16772 This is for the members text_lines, text_cols, total_lines, total_cols,
16773 where the system imposes an 'int' limit.
16775 * fringe.c (Fdefine_fringe_bitmap):
16776 Don't update size until alloc works.
16778 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16779 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16781 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16782 Check for size-calculation overflow.
16783 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16784 do, as we prefer signed integers.
16785 (id_to_widget.max_size, id_to_widget.used)
16786 (xg_store_widget_in_map, xg_remove_widget_from_map)
16787 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16788 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16789 Use and return ptrdiff_t, not int.
16790 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16791 * gtkutil.h: Change prototypes to match the above.
16793 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16794 are duplicate now that they've been promoted to lisp.h.
16795 (x_allocate_bitmap_record, x_alloc_image_color)
16796 (make_image_cache, cache_image, xpm_load):
16797 Don't update size until alloc is done.
16798 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)

16807 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16808 Use ptrdiff_t, not int, to count maps.
16809 (read_char_minibuf_menu_prompt): Check for overflow in size
16810 calculations. Don't update size until allocation succeeds.
16811 Redo calculations to avoid overflow.
16812 * keyboard.h: Change prototypes to match the above.
16814 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16816 (current_minor_maps): Check for size calculation overflow.
16817 * keymap.h: Change prototypes to match the above.
16819 * lread.c (read1, init_obarray): Don't update size until alloc done.
16821 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

16840 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16841 for command line length. Do not attempt to address one before the
16842 beginning of an array, as that's not portable.
16844 * term.c (max_frame_lines): Remove; unused.
16845 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16847 (encode_terminal_code, calculate_costs): Check for size
16848 calculation overflow.

16870 Use ptrdiff_t, not int, for sizes.
16871 (Finternal_make_lisp_face, cache_face):
16872 Check for size calculation overflow.
16873 (cache_face): Treat size calculation overflows as if they were
16874 memory exhaustion (the usual treatment), rather than aborting.
16876 * xfns.c (x_encode_text, x_set_name_internal)
16877 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16878 sizes, since they can exceed INT_MAX in size. Check for size
16879 calculation overflow.
16881 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16882 (xg_select): Check for size calculation overflow.
16883 Don't update size until alloc done.
16885 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16886 as sprintf is limited to int lengths.
16888 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16889 (X_LONG_MIN): New macros.
16890 Use them to make the following changes clearer.
16891 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16892 This change doesn't affect the value now, but it may help remind
16893 future maintainers not to raise the value too much later.
16894 (SELECTION_QUANTUM): Remove, replacing with ...
16895 (selection_quantum): ... new function, which avoids overflow.
16897 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16898 assumption that selection length fits in 'int'.

16902 (lisp_data_to_selection_data, clean_local_selection_data):
16903 Use ptrdiff_t, not int, to record length of selection.
16904 (x_reply_selection_request, x_get_window_property)
16905 (receive_incremental_selection, x_property_data_to_lisp):
16906 Redo calculations to avoid overflow.
16907 (x_reply_selection_request): When sending hint, ceiling it at
16908 X_LONG_MAX rather than relying on wraparound overflow to send
16910 (x_get_window_property, receive_incremental_selection)
16911 (lisp_data_to_selection_data, x_property_data_to_lisp):
16912 Check for size-calculation overflow.
16913 (x_get_window_property, receive_incremental_selection)

16915 Don't store size until memory allocation succeeds.
16916 (x_get_window_property): Plug memory leak on memory exhaustion.
16917 Don't double-block input; malloc is safe here. Don't assume 2**34
16918 - 4 fits in unsigned long. Add an xassert to check
16919 XGetWindowProperty overflow. Be more careful about overflow
16920 calculations, and distinguish size from memory overflow better.
16921 (receive_incremental_selection): When tracing, don't assume
16922 unsigned int is less than INT_MAX.
16923 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16924 harmful) conversions of unsigned short to int.
16925 (lisp_data_to_selection_data): Don't assume that integers
16926 in the range -65535 through -1 fit in an X unsigned short.
16927 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16928 result parameters unless successful. Rely on cons_to_unsigned
16929 to report problems with elements; the old code wasn't right anyway.
16930 (x_check_property_data): Check for int overflow; we cannot use
16931 a wider type due to X limits.
16932 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16934 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
16936 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
16937 (x_term_init): Check for size calculation overflow.
16938 (x_color_cells): Don't store size until memory allocation succeeds.
16939 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16940 Don't assume alloca size is less than MAX_ALLOCA.
16941 (x_term_init): Don't assume length fits in int (sprintf is limited
16944 Use ptrdiff_t for composition IDs.

16963 * image.c (xpm_get_color_table_h):
16964 * lisp.h (hash_lookup, hash_put):
16965 * minibuf.c (Ftest_completion):
16966 Use ptrdiff_t for hash table indexes, not int (which is too
16967 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16968 32-bit --with-wide-int hosts).
16970 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16971 Add a FIXME comment about memory leaks.
16972 (syms_of_charset): Don't assume xmalloc returns.

16976 * character.h (CHAR_WIDTH):
16977 * indent.c (MULTIBYTE_BYTES_WIDTH):
16978 Use sanitize_char_width to avoid undefined and/or bad behavior
16979 with outlandish widths.
16980 * character.h (sanitize_tab_width): Rename from sanitize_width,
16981 now that we have two such functions. All uses changed.
16982 (sanitize_char_width): New inline function.
16984 Don't assume that tab-width fits in int.
16985 * character.h (sanitize_width): New inline function.
16986 (SANE_TAB_WIDTH): New macro.
16987 (ASCII_CHAR_WIDTH): Use it.
16988 * indent.c (sane_tab_width): Remove. All uses replaced by

16992 * fileio.c: Integer overflow issues with file modes.
16993 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
16995 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
16996 Remove unreachable code.
16997 (read_hex, load_charset_map_from_file): Check for integer overflow.
16999 * xterm.c: Don't go over XClientMessageEvent limit.
17000 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17001 (x_send_scroll_bar_event): Likewise. Check that the size does not
17002 exceed limits imposed by XClientMessageEvent, as well as the usual
17003 ptrdiff_t and size_t limits.
17005 * keyboard.c: Overflow, signedness and related fixes.
17006 (make_lispy_movement): Use same integer type in forward decl
17007 that is used in the definition.
17008 (read_key_sequence, keyremap_step):
17009 Change bufsize argument back to int, undoing my 2011-03-30 change.
17010 We prefer signed types, and int is wide enough here.
17011 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17012 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17013 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17014 length, not size_t. Use ptrdiff_t for index, not int.
17015 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17016 possibility of integer overflow.
17018 Overflow, signedness and related fixes for images.
17020 * dispextern.h (struct it.stack[0].u.image.image_id)

17039 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
17040 (lookup_image): Remove unnecessary tests.
17041 (xbm_image_p): Locals are now of int, not EMACS_INT,
17042 since parse_image_check makes sure they fit into int.
17043 (png_load, gif_load, svg_load_image):
17044 Prefer int to unsigned where either will do.
17045 (tiff_handler): New function, combining the cores of the
17046 old tiff_error_handler and tiff_warning_handler.
17047 This function is rewritten to use vsnprintf and thereby avoid
17048 stack buffer overflows. It uses only the features of vsnprintf
17049 that are common to both POSIX and native Microsoft.
17050 (tiff_error_handler, tiff_warning_handler): Use it.
17051 (tiff_load, gif_load, imagemagick_load_image):
17052 Don't assume :index value fits in 'int'.
17053 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17054 (imagemagick_load_image): Check that crop parameters fit into
17055 the integer types that MagickCropImage accepts. Don't assume
17056 Vimagemagick_render_type has a nonnegative value. Don't assume
17057 size_t fits in 'long'.
17058 (gs_load): Use printmax_t to print the widest integers possible.
17059 Check for integer overflow when computing image height and width.
17061 2011-08-26 Eli Zaretskii <eliz@gnu.org>
17063 * xdisp.c (redisplay_window): Don't force window start if point
17064 will be invisible in the resulting window. (Bug#9324)

17068 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
17069 the display spec is of the form `(space ...)'.
17070 (handle_display_spec): Return the value returned by
17071 handle_single_display_spec, not just 1 or zero.
17072 (handle_single_display_spec): If the display spec is of the form
17073 `(space ...)', and specifies display in the text area, return 2
17075 (try_cursor_movement): Check for the need to scroll more
17076 accurately, and prefer exact match for point under bidi.
17077 Don't advance `row' beyond the last row of the window.
17079 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
17080 into disp_prop; all users changed.
17082 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
17083 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
17084 for the text covered by the display property.

17094 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
17095 buffers, return left-to-right.
17096 (set_cursor_from_row): Consider candidate row a win if its glyph
17097 represents a newline and point is on that newline. Fixes cursor
17098 positioning on the newline at EOL of R2L text within L2R
17099 paragraph, and vice versa.
17100 (try_cursor_movement): Check continued rows, in addition to
17101 continuation rows. Fixes unwarranted scroll when point enters a
17102 continued line of R2L text within an L2R paragraph, or vice versa.
17103 (cursor_row_p): Consider the case of point being equal to
17104 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17105 from the end of a short line to the beginning of a continued line
17106 of R2L text within L2R paragraph.
17107 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
17108 composed characters.

17123 2011-08-22 Kenichi Handa <handa@m17n.org>
17125 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
17126 extra slot even if the purpose is char-code-property-table.
17128 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17130 * xdisp.c (redisplay_window): When computing centering_position,
17131 account for the height of the header line. (Bug#8874)
17133 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17134 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17135 candidate is selected by the mouse, and that candidate has a
17136 composed character under the mouse.
17138 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17139 coordinates reported by pos-visible-in-window-p for a composed
17140 character in column zero.
17142 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
17144 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
17146 2011-08-22 Eli Zaretskii <eliz@gnu.org>
17148 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17149 consider it a hit if to_charpos is anywhere in the range of the
17150 composed buffer positions.
17152 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17154 * image.c (gif_load): Don't assume that each subimage has the same
17155 dimensions as the base image. Handle disposal method that is
17156 "undefined" by the gif spec (Bug#9335).
17158 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17160 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
17161 (Fcondition_case): Document `debug' symbol in error handler.
17163 2011-08-19 Eli Zaretskii <eliz@gnu.org>
17165 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17166 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17167 from an Org mode buffer to a Speedbar frame.
17169 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17170 a composition, take its buffer position from IT->cmp_it.charpos.
17171 Fixes cursor positioning at the beginning of a line that begins
17172 with a composed character.
17174 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17176 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17177 character bidirectional type, use STRONG_L instead. Fixes crashes
17178 in a buffer produced by `describe-categories'.
17180 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17181 members before the level stack, so they would be saved and
17182 restored when copying iterator state. Fixes incorrect reordering
17183 around TABs covered by display properties.
17185 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17187 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

17191 * eval.c (internal_condition_case, internal_condition_case_1)
17192 (internal_condition_case_2, internal_condition_case_n):
17193 Remove unnecessary aborts (Bug#9081).
17195 2011-08-17 Eli Zaretskii <eliz@gnu.org>
17197 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
17198 has no `load' handler, try opening the file locally. (Bug#9311)
17200 2011-08-16 Ken Brown <kbrown@cornell.edu>

17206 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
17207 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
17209 2011-08-16 Ken Brown <kbrown@cornell.edu>
17211 Fix memory allocation problems in Cygwin build (Bug#9273).
17213 * unexcw.c ( __malloc_initialized): Declare external variable.
17214 (fixup_executable): Force the dumped emacs to reinitialize malloc.
17216 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
17218 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

17246 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
17247 coordinates of the iterator when restoring from ppos_it.
17250 2011-08-14 Kenichi Handa <handa@m17n.org>
17252 * process.c (create_process): Call setup_process_coding_systems
17253 after the pid of the process is set to -1 (Bug#8162).
17255 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17257 * xdisp.c (move_it_in_display_line_to): Don't invoke
17258 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17259 ppos_it. Fixes vertical cursor motion when line beginning is
17260 covered by an image. (Bug#9296)
17262 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17264 * nsterm.h (ns_run_ascript): Declare.

17267 * nsfns.m (as_script, as_result, as_status): New static variables.
17268 (ns_run_ascript): New function.
17269 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17270 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17271 the event loop. Get status from as_status (Bug#7276).
17273 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17274 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17275 the event loop (Bug#7276).
17277 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17279 * gnutls.c (QCgnutls_bootprop_priority)

17300 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
17301 (Fnetwork_interface_list): Allocate in increments of bytes instead
17302 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17303 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17305 (struct ifflag_def): notrailers is smart on OSX.
17306 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17307 Get hardware address with getifaddrs if available.
17309 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17311 * xdisp.c (iterate_out_of_display_property): xassert that
17312 IT->position is set to within IT->object's boundaries. Break from
17313 the loop as soon as EOB is reached; avoids infloops in redisplay
17314 when IT->position is set up wrongly due to some bug.
17315 Set IT->current to match the bidi iterator unconditionally.
17316 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17317 entry. Force push_it to save on the stack the current
17318 buffer/string position, to be restored by pop_it. Fix flags in
17319 the iterator structure wrt the object coming from a display
17320 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17321 properties. (Bug#9284)
17323 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17325 * fontset.c (fontset_get_font_group): Add proper type checks.

17335 2011-08-08 Eli Zaretskii <eliz@gnu.org>
17337 * xdisp.c (forward_to_next_line_start): Allow to use the
17338 no-display-properties-and-no-overlays under bidi display.
17339 Set disp_pos in the bidi iterator to avoid searches for display
17340 properties and overlays.

17348 the font entity extracted from the cache (Bug#8109).
17350 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17352 * composite.c (autocmp_chars): Don't reset point. That is done by
17353 restore_point_unwind (Bug#5984).
17355 2011-08-07 Juri Linkov <juri@jurta.org>
17357 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17358 to show the arg `TIME' instead of `TIMEVAL'.
17360 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17362 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17363 display property strides EOL and includes a newline, as in
17364 longlines-mode. (Bug#9254)
17365 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17366 word-wrap under bidirectional display. (Bug#9224)
17368 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17369 is non-zero, even if the data buffer is NULL. Fixes a crash in
17370 vertical-motion with longlines-mode. (Bug#9254)
17372 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17374 * bidi.c <bidi_cache_total_alloc>: Now static.
17375 (bidi_initialize): Initialize bidi_cache_total_alloc.
17377 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17380 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17381 amount allocated this far in `bidi_cache_total_alloc'.
17382 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17383 non-zero, only free the data buffer without restoring the cache
17384 contents. All callers changed.
17386 * dispextern.h (bidi_unshelve_cache): Update prototype.
17388 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17389 (move_it_in_display_line, move_it_to)
17390 (move_it_vertically_backward, move_it_by_lines): Replace the call
17391 to xfree to an equivalent call to bidi_unshelve_cache.
17392 (move_it_in_display_line_to): Fix logic of returning
17393 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17395 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17397 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17398 came from a string character with a `cursor' property. (Bug#9229)
17400 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17402 * Makefile.in (LIB_PTHREAD): New variable.
17403 (LIBES): Add LIB_PTHREAD (Bug#9216).
17405 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17406 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17408 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17410 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17412 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17414 * xterm.c (x_find_topmost_parent): New function.
17415 (x_set_frame_alpha): Find topmost parent window with
17416 x_find_topmost_parent and set the property there also (bug#9181).
17417 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17419 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17421 * callproc.c (Fcall_process): Avoid vfork clobbering
17422 the local vars buffer, coding_systems, current_dir.
17424 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17426 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17428 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17430 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17431 so that it is not optimized away.
17433 * xdisp.c (compute_display_string_pos): Remove unused local.
17435 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17437 Fix slow cursor motion and scrolling in large buffers with
17438 selective display, like Org Mode buffers. (Bug#9218)
17440 * dispextern.h (struct bidi_it): New member disp_prop_p.
17442 * xdisp.c: Remove one-slot cache of display string positions.
17443 (compute_display_string_pos): Accept an additional argument
17444 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17445 for a display string or property. If found, set DISP_PROP_P
17448 * bidi.c (bidi_fetch_char): Accept an additional argument
17449 DISP_PROP_P, and pass it to compute_display_string_pos.
17450 Only handle text covered by a display string if DISP_PROP_P is returned
17451 non-zero. All callers of bidi_fetch_char changed.
17453 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17455 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17457 2010-12-03 Don March <don@ohspite.net>
17459 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17460 last character M-[char] is translated to ESC [char] (bug#7541).
17462 2011-08-02 Kenichi Handa <handa@m17n.org>
17464 * lisp.h (uniprop_table): Extern it.
17466 * chartab.c (uniprop_table): Make it non-static.
17468 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17470 * xdisp.c (forward_to_next_line_start): Accept additional argument
17471 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17473 (reseat_at_next_visible_line_start): Use the bidi iterator state
17474 returned by forward_to_next_line_start to restore the state of
17475 it->bidi_it after backing up to previous newline. (Bug#9212)
17477 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17479 * regex.c (re_comp): Protoize.
17480 (re_exec): Fix return type.
17481 (regexec): Fix type of `ret'. (Bug#9203)
17483 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17485 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17486 This is needed if max-image-size is a floating-point number.
17488 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17490 * print.c (print_object): Print empty symbol as ##.
17492 * lread.c (read1): Read ## as empty symbol.
17494 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17496 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17497 setting frame foreground color (Bug#9175).
17498 (x_set_background_color): Likewise.
17500 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17501 contents (Bug#9176).
17502 (EmacsTooltip -init): Remove bezels and add shadows to
17505 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17506 or scroll bar (Bug#8470).
17508 * nsfont.m (nsfont_open): Remove assignment to voffset and
17509 unnecessary vars hshink, expand, hd, full_height, min_height.
17510 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17512 * nsterm.h (nsfont_info): Remove voffset field.
17514 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17516 Implement strike-through and overline on NextStep (Bug#8863).
17518 * nsfont.m (nsfont_open): Use underline position provided by font,
17519 instead of hard-coded value of 2.
17520 (nsfont_draw): Call ns_draw_text_decoration instead.
17522 * nsterm.h: Add declaration for ns_draw_text_decoration.
17524 * nsterm.m (ns_draw_text_decoration): New function for drawing
17525 underline, overline, and strike-through.
17526 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17527 ns_draw_text_decoration. Change treatment of cursor drawing to
17528 accommodate underlining, etc.
17530 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17532 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17535 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17537 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17538 Without this fix, if a signal arrives just after memory fills up,
17539 'malloc' might be invoked reentrantly.
17541 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17542 In other words, assume that every image size is allowed, on non-X
17543 hosts. This assumption is probably wrong, but it lets Emacs compile.
17545 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17547 * regex.c (re_iswctype): Convert return values to boolean.
17549 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17551 * xdisp.c (compute_display_string_pos): Don't use cached display
17552 string position if the buffer had its restriction changed.
17555 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17557 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17559 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17561 Integer signedness and overflow and related fixes. (Bug#9079)
17563 * bidi.c: Integer size and overflow fixes.
17564 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17565 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17566 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17567 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17568 (bidi_find_other_level_edge):
17569 Use ptrdiff_t instead of EMACS_INT where either will do.
17570 This works better on 32-bit hosts configured --with-wide-int.
17571 (bidi_cache_ensure_space): Check for size-calculation overflow.
17572 Use % rather than repeated addition, for better worst-case speed.
17573 Don't set bidi_cache_size until after xrealloc returns, because it
17575 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17576 (bidi_cache_ensure_space): Also check that the bidi cache size
17577 does not exceed that of the largest Lisp string or buffer. See Eli
17578 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17580 * alloc.c (__malloc_size_t): Remove.
17581 All uses replaced by size_t. See Andreas Schwab's note
17582 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17584 * image.c: Improve checking for integer overflow.
17585 (check_image_size): Assume that f is nonnull, since
17586 it is always nonnull in practice. This is one less thing to
17587 worry about when checking for integer overflow later.
17588 (x_check_image_size): New function, which checks for integer
17589 overflow issues inside X.
17590 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17591 This removes the need for a memory_full check.
17592 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17593 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17594 (xbm_read_bitmap_data): Change locals back to 'int', since
17595 their values must fit in 'int'.
17596 (xpm_load_image, png_load, tiff_load):
17597 Invoke x_create_x_image_and_pixmap earlier,
17598 to avoid much needless work if the image is too large.
17599 (tiff_load): Treat overly large images as if
17600 x_create_x_image_and_pixmap failed, not as malloc failures.
17601 (gs_load): Use x_check_image_size.
17603 * gtkutil.c: Omit integer casts.
17604 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17605 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17607 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17609 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17610 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17611 would wrongly return t on a 64-bit host.
17613 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17614 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17615 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17616 and therefore cause GCC to emit a bogus diagnostic in some cases.
17618 * image.c: Integer signedness and overflow and related fixes.
17619 This is not an exhaustive set of fixes, but it's time to
17620 record what I've got.
17621 (lookup_pixel_color, check_image_size): Remove redundant decls.
17622 (check_image_size): Don't assume that arbitrary EMACS_INT values
17623 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17624 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17625 (tiff_load, imagemagick_load_image):
17626 Check for overflow in size calculations.
17627 (x_create_x_image_and_pixmap): Remove unnecessary test for
17628 xmalloc returning NULL; that can't happen.
17629 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17630 (xpm_color_bucket): Use better integer hashing function.
17631 (xpm_cache_color): Don't possibly over-allocate memory.
17632 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17633 (gif_memory_source):
17634 Use ptrdiff_t, not int or size_t, to record sizes.
17635 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17636 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17637 either works, as we prefer signed integers.
17638 (tiff_read_from_memory, tiff_write_from_memory):
17639 Return tsize_t, not size_t, since that's what the TIFF API wants.
17640 (tiff_read_from_memory): Don't fail simply because the read would
17641 go past EOF; instead, return a short read.
17642 (tiff_load): Omit no-longer-needed casts.
17643 (Fimagemagick_types): Don't assume size fits into 'int'.
17645 Improve hashing quality when configured --with-wide-int.
17646 * fns.c (hash_string): New function, taken from sxhash_string.
17647 Do not discard information about ASCII character case; this
17648 discarding is no longer needed.
17649 (sxhash-string): Use it. Change sig to match it. Caller changed.
17650 * lisp.h: Declare it.
17651 * lread.c (hash_string): Remove, since we now use fns.c's version.
17652 The fns.c version returns a wider integer if --with-wide-int is
17653 specified, so this should help the quality of the hashing a bit.
17655 * emacs.c: Integer overflow minor fix.
17656 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17657 Define only if GNU_LINUX.
17658 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17660 * dispnew.c: Integer signedness and overflow fixes.
17661 Remove unnecessary forward decls, that were a maintenance hassle.
17662 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17664 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17665 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17666 (prepare_desired_row, line_draw_cost):
17667 Use int, not unsigned, where either works.
17668 (save_current_matrix, restore_current_matrix):
17669 Use ptrdiff_t, not size_t, where either works.
17670 (init_display): Check for overflow more accurately, and without
17671 relying on undefined behavior.
17673 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17674 Remove, replacing with the new symbols in lisp.h. All uses changed.
17675 * fileio.c (make_temp_name):
17676 * filelock.c (lock_file_1, lock_file):
17677 * xdisp.c (message_dolog):
17678 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17679 Use pMd etc. instead.
17680 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17681 replacing the pWIDE etc. symbols removed from editfns.c.
17683 * keyboard.h (num_input_events): Now uintmax_t.
17684 This is (very slightly) less likely to mess up due to wraparound.
17687 * buffer.c: Integer signedness fixes.
17688 (alloc_buffer_text, enlarge_buffer_text):
17689 Use ptrdiff_t rather than size_t when either will do, as we prefer
17692 * alloc.c: Integer signedness and overflow fixes.
17693 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17694 (__malloc_size_t): Default to size_t, not to int.
17695 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17696 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17697 Prefer ptrdiff_t to size_t when either would do, as we prefer
17699 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17700 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17701 Now const. Initialize with values that are in range even if char
17703 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17704 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17705 These functions do the right thing with sizes > 2**32.
17706 (check_depth): Now ptrdiff_t, not int.
17707 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17708 Adjust to new way of storing sizes. Check for size overflow bugs
17710 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17711 slightly wrong anyway, as it missed one instance of
17712 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17713 (refill_memory_reserve): Omit needless cast to size_t.
17714 (mark_object_loop_halt): Mark as externally visible.
17716 * xselect.c: Integer signedness and overflow fixes.
17717 (Fx_register_dnd_atom, x_handle_dnd_message):
17718 Use ptrdiff_t, not size_t, since we prefer signed.
17719 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17720 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17721 x_dnd_atoms_size and x_dnd_atoms_length.
17723 * doprnt.c: Prefer signed to unsigned when either works.
17725 * doprnt.c (doprnt):
17727 * xdisp.c (vmessage):
17728 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17729 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17730 prefer signed arithmetic to avoid comparison confusion.
17731 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17732 but is a bit tricky.
17734 Assume freestanding C89 headers, string.h, stdlib.h.
17735 * data.c, doprnt.c, floatfns.c, print.c:
17736 Include float.h unconditionally.
17737 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17738 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17739 * regex.c: Likewise for stddef.h, string.h.
17740 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17741 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17742 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17743 (STDC_HEADERS): Remove obsolete defines.
17744 * sysdep.c: Include limits.h unconditionally.
17746 Assume support for memcmp, memcpy, memmove, memset.
17747 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17748 * regex.c (memcmp, memcpy):
17749 Remove; we assume C89 now.
17751 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17752 (__malloc_safe_bcopy): Remove; no longer needed.
17754 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17755 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17756 well either way, and we prefer signed to unsigned.
17758 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17760 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17761 closes the connection while we're reading (bug#9182).
17763 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17765 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17766 are specified (Bug#9168).
17768 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17770 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17771 Found by GCC static checking and --with-wide-int on a 32-bit host.
17773 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17775 * xdisp.c (compute_display_string_pos): Fix logic of caching
17776 previous display string position. Initialize cached_prev_pos to
17777 -1. Fixes slow-down at the beginning of a buffer.
17779 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17781 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17782 for attrs[LFACE_FONTSET_INDEX].
17784 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17786 * xml.c (parse_region): Remove unused local
17787 that was recently introduced.
17789 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17791 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17792 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17794 * xdisp.c (move_it_in_display_line_to): Record the best matching
17795 position for TO_CHARPOS while scanning the line, and restore it on
17796 exit if none of the characters scanned was an exact match.
17797 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17798 when exact match is impossible due to invisible text, and the
17799 lines are truncated.
17801 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17803 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17806 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17808 Fix a significant slow-down of cursor motion with C-n, C-p,
17809 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17810 auto-repeat under bidi redisplay in fontified buffers.
17811 * xdisp.c (compute_stop_pos_backwards): New function.
17812 (next_element_from_buffer): Call compute_stop_pos_backwards to
17813 find a suitable prev_stop when we find ourselves before
17815 (reseat): Don't look for prev_stop, as that could mean a very long
17817 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17818 <cached_disp_overlay_modiff>: Cache for last found display string
17820 (compute_display_string_pos): Return the cached position if asked
17821 about the same buffer in the same area of character positions, and
17822 the buffer wasn't changed since the time the display string
17823 position was cached.
17825 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17827 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17828 is an integer, which is important for empty lines. (Bug#9149)
17830 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17832 * frame.c (Fmodify_frame_parameters): In tty case, update the
17833 default face if necessary (Bug#4238).
17835 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17837 * editfns.c (Fstring_to_char): No need to explain what a character
17838 is in the docstring (Bug#6576).
17840 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17842 * xml.c (parse_region): Make sure we always return a tree.
17844 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17846 * xml.c (parse_region): If a document contains only comments,
17849 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17851 * xml.c (make_dom): Return comments, too.
17853 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17856 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17857 and the surrounding thread.
17858 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17859 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17860 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17862 * s/openbsd.h (BROKEN_SIGIO): Define.
17863 * unexelf.c (unexec) [__OpenBSD__]:
17864 Don't update the .mdebug section of the Alpha COFF symbol table.
17866 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17868 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17871 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17873 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17874 This fixes some race conditions on the permissions of any newly
17877 * alloc.c (valid_pointer_p): Use pipe, not open.
17878 This fixes some permissions issues when debugging.
17880 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17881 If fchown fails to set both uid and gid, try to set just gid,
17882 as that is sometimes allowed. Adjust the file's mode to eliminate
17883 setuid or setgid bits that are inappropriate if fchown fails.
17885 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17887 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17888 to compare Lisp_Objects.

17891 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17893 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17895 * lread.c (read_integer): Unread even EOF character.
17896 (read1): Likewise. Properly record start position of symbol.
17898 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17899 symbol character follows.
17901 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17903 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17904 This works around a problem with the previous change to Fcopy_file.
17905 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17906 and without this change, GCC might complain about discarding
17907 fchown's return value.
17909 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17911 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17913 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17915 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17917 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17919 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17920 it's used from the C level.
17922 * process.c: Use the same condition for POLL_FOR_INPUT in both
17923 keyboard.c and process.c (bug#1858).
17925 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17927 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17928 (Fgnutls_boot): Use it.
17930 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17932 * doc.c (Fsubstitute_command_keys): Revert last change.
17934 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17936 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17937 quotes the next character, and doesn't affect other longer
17938 sequences (bug#8935).
17940 * lread.c (syms_of_lread): Clarify that is isn't only
17941 `eval-buffer' and `eval-defun' that's affected by
17942 `lexical-binding' (bug#8460).
17944 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17946 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17947 bidi redisplay when a line includes both an image and is truncated.
17949 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17951 Fix minor problems found by static checking.
17952 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17953 (elsz): Now a signed constant, not a size_t var. We prefer signed
17954 types to unsigned, to avoid integer comparison confusion. Without
17955 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17956 "cannot optimize loop, the loop counter may overflow", a symptom
17958 * indent.c (Fvertical_motion): Mark locals as initialized.
17959 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17961 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17963 * search.c (Fre_search_backward): Mention `case-fold-search' in
17964 all the re_search_* functions (bug#8138).
17966 * keyboard.c (Fopen_dribble_file): Document when the file is

17984 buffer position was specified. Initialize paragraph_embedding to
17986 (reseat_to_string): Initialize the bidi iterator.
17987 (display_string): If we need to ignore text properties of
17988 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17989 original value of -1 will not work with bidi.)
17990 (compute_display_string_pos): First arg is now struct
17991 `text_pos *'; all callers changed. Support display properties on
17993 (compute_display_string_end): Support display properties on Lisp
17995 (init_iterator, reseat_1, reseat_to_string): Initialize the
17996 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17997 when iterating on a string not from display properties).
17998 (compute_display_string_pos, compute_display_string_end):
17999 Fix calculation of the object to scan. Fixes an error when using
18001 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18002 base_level_stop; instead, set base_level_stop to BEGV.
18003 Fixes crashes in vertical-motion.
18004 (next_element_from_buffer): Improve commentary for when
18005 the iterator is before prev_stop.
18006 (init_iterator): Initialize bidi_p from the default value of
18007 bidi-display-reordering, not from buffer-local value. Use the
18008 buffer-local value only if initializing for buffer iteration.
18009 (handle_invisible_prop): Support invisible properties on strings
18010 that are being bidi-reordered.
18011 (set_iterator_to_next): Support bidi reordering of C strings and

18017 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18018 (init_iterator): Don't initialize it->bidi_p for strings
18020 (reseat_to_string): Initialize it->bidi_p for strings here.
18021 (next_element_from_string, next_element_from_c_string)
18022 (next_element_from_buffer): Add xassert's for correspondence

18027 character that is not the first one in the visual order.
18028 (get_visually_first_element): New function, refactored from common
18029 parts of next_element_from_buffer, next_element_from_string, and
18030 next_element_from_c_string.
18031 (tool_bar_lines_needed, redisplay_tool_bar)
18032 (display_menu_bar): Force left-to-right direction. Add a FIXME
18033 comment for making that be controlled by a user option.
18034 (push_it, pop_it): Save and restore the state of the
18035 bidi iterator. Save and restore the bidi_p flag.
18036 (pop_it): Iterate out of display property for string iteration as

18039 (handle_single_display_spec): Set up it->bidi_it for iteration
18040 over a display string, and call bidi_init_it.

18042 (get_overlay_strings_1, push_display_prop): Set up the bidi
18043 iterator for displaying display or overlay strings.
18044 (forward_to_next_line_start): Don't use the shortcut if
18046 (back_to_previous_visible_line_start): If handle_display_prop
18047 pushed the iterator stack, restore the internal state of the bidi
18048 iterator by calling bidi_pop_it same number of times.
18049 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18050 and we are bidi-iterating, don't decrement the iterator position;
18051 instead, set the first_elt flag in the bidi iterator, to produce
18053 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18054 (push_display_prop): xassert that we are iterating a buffer.
18055 (push_it, pop_it): Save and restore paragraph_embedding member.
18056 (handle_single_display_spec, next_overlay_string)
18057 (get_overlay_strings_1, reseat_1, reseat_to_string)
18058 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18059 correctly. Don't assume unibyte strings are not bidi-reordered.
18060 (compute_display_string_pos)
18061 (compute_display_string_end): Fix handling the case of C string.
18062 (push_it, pop_it): Save and restore from_disp_prop_p.

18065 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
18066 (pop_it): Call iterate_out_of_display_property only if we are
18067 popping after iteration over a string that came from a display
18068 property. Fix a typo in popping stretch info. Add an assertion
18069 for verifying that the iterator position is in sync with the bidi
18071 (handle_single_display_spec, get_overlay_strings_1)
18072 (push_display_prop): Fix initialization of paragraph direction for
18073 string when that of the parent object is not yet determined.

18075 iterator with IT's position. (Bug#7616)
18076 (find_row_edges): If ROW->start.pos gives position
18077 smaller than min_pos, use it as ROW->minpos. (Bug#7616)

18079 Reset the from_disp_prop_p flag.
18080 (SAVE_IT, RESTORE_IT): New macros.

18085 (try_scrolling, redisplay_window, display_line): Use them when
18086 saving a temporary copy of the iterator and restoring it back.
18087 (back_to_previous_visible_line_start, reseat_1)
18088 (init_iterator): Empty the bidi cache "stack".
18089 (move_it_in_display_line_to): If iterator ended up at
18090 EOL, but we never saw any buffer positions smaller than
18091 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
18092 motion in bidi-reordered lines.
18093 (move_it_in_display_line_to): Record prev_method and prev_pos
18094 immediately before the call to set_iterator_to_next. Fixes cursor

18096 displayed in margins. (Bug#8133) (Bug#8867)
18097 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
18099 (pos_visible_p): Support positions in bidi-reordered lines.
18100 Save and restore bidi cache.
18102 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
18103 (bidi_paragraph_info): Delete unused struct.
18104 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
18105 (bidi_cache_start): New variable.

18121 Support iteration over a string.
18122 (bidi_set_sor_type, bidi_resolve_explicit_1)
18123 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
18124 can now be zero (for strings); special values 0 and -1 were
18125 changed to -1 and -2, respectively.
18126 (bidi_char_at_pos): New function.
18127 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

18138 (bidi_initialize): Initialize the bidi cache start stack pointer.
18139 (bidi_cache_ensure_space): New function, refactored from part of

18155 * dispextern.h (struct bidi_string_data): New structure.
18156 (struct bidi_it): New member `string'. Make flag members be 1-bit
18157 fields, and put them last in the struct.
18158 (compute_display_string_pos, compute_display_string_end):
18160 (bidi_push_it, bidi_pop_it): Add prototypes.
18161 (struct iterator_stack_entry): New members bidi_p,
18162 paragraph_embedding, and from_disp_prop_p.
18163 (struct it): Member bidi_p is now a bit field 1 bit wide.
18164 (bidi_shelve_cache, bidi_unshelve_cache):
18165 Declare prototypes.
18167 * .gdbinit (xvectype, xvector, xcompiled, xchartable, xboolvector)

18185 * indent.c (Fvertical_motion): Set and restore w->pointm when
18186 saving and restoring the window's buffer (Bug#9006).

18209 (x_handle_selection_clear,x_clear_frame_selections):
18210 Pass Qx_lost_selection_functions rather than
18211 Vx_lost_selection_functions to Frun_hook_with_args.
18213 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
18215 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
18216 The old code sometimes used this field without initializing it.
18218 * alloc.c (gc_sweep): Don't read past end of array.
18219 In theory, the old code could also have corrupted Emacs internals,

18525 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18526 subseconds part to the entropy, as that's a bit more random.
18527 Prefer signed to unsigned, since the signedness doesn't matter and
18528 in general we prefer signed. When given a limit, use a
18529 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18530 latter isn't right if USE_2_TAGS_FOR_INTS.
18531 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18532 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18545 This is more efficient than Ffile_directory_p and avoids a minor race.

18549 * buffer.c (Foverlay_put): Say what the return value is
18552 * fileio.c (barf_or_query_if_file_exists): Check first if the file

18556 error be more correct.

18575 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

18675 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
18677 * eval.c (struct backtrace): Simplify and port the data structure.
18678 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18679 signed bit field, as this assumption is not portable and it makes
18680 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18681 "char debug_on_exit : 1" as this is not portable either; instead,
18682 use the portable "unsigned int debug_on_exit : 1". Remove unused
18683 member evalargs. Remove obsolete comments about cc bombing out.
18685 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18753 (emacs_fixed_new): Set priv->f to argument.
18754 (emacs_fixed_get_preferred_width)
18755 (emacs_fixed_get_preferred_height): Use min_width/height from
18756 frames size_hint to set minimum and natural (Bug#8919).
18757 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18758 and use min_width/height from frames size_hint to set
18759 min_width/height (Bug#8919).

18779 Use gnulib's dup2 module instead of rolling our own.
18780 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

18847 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
18849 Integer and buffer overflow fixes (Bug#8873).
18851 * print.c (printchar, strout): Check for string overflow.
18852 (PRINTPREPARE, printchar, strout):
18853 Don't set size unless allocation succeeds.
18855 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18856 for sizes. Check for string overflow more accurately.
18857 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
18859 * macros.c: Integer and buffer overflow fixes.
18860 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18861 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

18865 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
18867 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18869 * lread.c: Integer overflow fixes.
18870 (read_integer): Radix is now EMACS_INT, not int,
18871 to improve quality of diagnostics for out-of-range radices.
18872 Calculate buffer size correctly for out-of-range radices.
18873 (read1): Check for integer overflow in radices, and in
18874 read-circle numbers.
18875 (read_escape): Avoid int overflow.
18876 (Fload, openp, read_buffer_size, read1)
18877 (substitute_object_recurse, read_vector, read_list, map_obarray):
18878 Use ptrdiff_t, not int, for sizes.

18893 2011-06-22 Leo Liu <sdl.web@gmail.com>
18895 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18896 Move to minibuffer.el.
18898 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18900 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18901 The following patches are for when GLYPH_DEBUG && !XASSERT.
18902 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18903 * dispnew.c (flush_stdout):
18904 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18905 Mark as externally visible.
18906 * dispnew.c (check_window_matrix_pointers): Now static.
18907 * dispnew.c (window_to_frame_vpos):
18908 * xfns.c (unwind_create_frame):
18909 * xterm.c (x_check_font): Remove unused local.
18910 * scroll.c (CHECK_BOUNDS):
18911 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18912 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18913 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18914 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18915 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18917 (debug_method_add): Use va_list and vsprintf rather than relying
18918 on undefined behavior with wrong number of arguments.
18919 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18920 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18921 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18922 since we're not interested in debugging glyphs with old libraries.
18923 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18924 GCC 4.6.0's static checking.
18926 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18928 Integer overflow and signedness fixes (Bug#8873).

18940 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18942 * xfaces.c (load_pixmap):

18944 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18945 (.bitmaps_last, struct x_output.icon_bitmap):
18946 Use ptrdiff_t, not int, for bitmap indexes.
18947 (x_allocate_bitmap_record): Check for size overflow.
18948 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18950 Use ptrdiff_t, not int, for overlay counts.
18951 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18952 * editfns.c (overlays_around, get_pos_property):
18953 * textprop.c (get_char_property_and_overlay):
18954 * xdisp.c (next_overlay_change, note_mouse_highlight):
18955 * xfaces.c (face_at_buffer_position):
18956 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18957 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18958 (Fnext_overlay_change, Fprevious_overlay_change)
18959 (mouse_face_overlay_overlaps, Foverlays_in):
18960 Use ptrdiff_t, not int, for sizes.
18961 (overlays_at, overlays_in): Check for size-calculation overflow.
18963 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18965 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18966 (x_session_initialize): Do not assume string length fits in int.
18968 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18969 This is unlikely, but can occur if DPI is outlandish.
18971 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
18972 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
18974 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
18975 * xrdb.c (magic_file_p, search_magic_path):
18976 Omit last arg SUFFIX; it was always 0. All callers changed.
18977 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
18979 * xfont.c (xfont_match): Avoid need for strlen.
18981 * xfns.c: Don't assume strlen fits in int.

18984 * xdisp.c (message_log_check_duplicate): Return intmax_t,
18985 not unsigned long, as we prefer signed integers. All callers changed.
18986 Detect integer overflow in repeat count.
18987 (message_dolog): Don't assume print length fits in 39 bytes.
18988 (display_mode_element): Don't assume strlen fits in int.
18990 * termcap.c: Don't assume sizes fit in int and never overflow.
18991 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
18992 (gobble_line): Check for size-calculation overflow.
18994 * minibuf.c (Fread_buffer):
18995 * lread.c (intern, intern_c_string):
18996 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

19007 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19009 * filelock.c: Fix some buffer overrun and integer overflow issues.
19010 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19011 Reformulate so as not to need the command string.
19012 Invoke gzip -cd rather than gunzip, as it's more portable.
19013 (lock_info_type, lock_file_1, lock_file):
19014 Don't assume pid_t and time_t fit in unsigned long.
19015 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19016 (current_lock_owner): Prefer signed type for sizes.
19017 Use memcpy, not strncpy, where memcpy is what is really wanted.
19018 Don't assume (via atoi) that time_t and pid_t fit in int.
19019 Check for time_t and/or pid_t out of range, e.g., via a network share.
19020 Don't alloca where an auto var works fine.
19022 * fileio.c: Fix some integer overflow issues.
19023 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19024 Don't assume string length fits in int.
19025 (directory_file_name): Don't assume string length fits in long.
19026 (make_temp_name): Don't assume pid fits in int, or that its print
19027 length is less than 20.
19029 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19031 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19033 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19035 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19036 We prefer signed integers, even for size calculations.
19038 * emacs.c: Don't assume string length fits in 'int'.
19039 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19040 (main): Don't invoke strlen when not needed.

19046 (Fgetenv_internal):
19047 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19049 * lread.c (invalid_syntax): Omit length argument.
19050 All uses changed. This doesn't fix a bug, but it simplifies the
19051 code away from its former Hollerith-constant appearance, and it's
19052 one less 'int' to worry about when looking at integer-overflow issues.
19053 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19055 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19056 This didn't break anything, but it didn't help either.
19057 It's confusing to put a bogus integer in a place where the actual
19058 value does not matter.
19059 (LIST_END_P): Remove unused macro and its bogus comment.
19060 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19062 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19063 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19065 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19066 We prefer signed types, and the value cannot exceed the EMACS_INT
19067 range anyway (because otherwise the length would not be representable).
19068 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19069 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19070 This avoids a GCC warning when WIDE_EMACS_INT.
19072 * indent.c (sane_tab_width): New function.
19073 (current_column, scan_for_column, Findent_to, position_indentation)
19074 (compute_motion): Use it. This is just for clarity.
19075 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19077 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19079 * lisp.h (lint_assume): New macro.
19080 * composite.c (composition_gstring_put_cache):
19081 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19083 * editfns.c, insdel.c:
19084 Omit unnecessary forward decls, to simplify future changes.
19086 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19088 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19090 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19091 Use much-faster test for byte-length change.
19092 Don't assume string byte-length fits in 'int'.
19093 Check that character arg fits in 'int'.
19094 (mapcar1): Declare byte as byte, for clarity.
19096 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19098 * fns.c (concat): Catch string overflow earlier.
19099 Do not rely on integer wraparound.
19101 * dispextern.h (struct it.overlay_strings_charpos)
19102 (struct it.selective): Now EMACS_INT, not int.
19103 * xdisp.c (forward_to_next_line_start)
19104 (back_to_previous_visible_line_start)
19105 (reseat_at_next_visible_line_start, next_element_from_buffer):
19106 Don't arbitrarily truncate the value of 'selective' to int.
19108 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19110 * composite.c: Don't truncate sizes to 'int'.
19111 (composition_gstring_p, composition_reseat_it)
19112 (composition_adjust_point): Use EMACS_INT, not int.
19113 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19114 not EMACS_UINT, for indexes.
19116 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19118 * buffer.c: Include <verify.h>.
19119 (struct sortvec.priority, struct sortstr.priority):
19120 Now EMACS_INT, not int.
19121 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19122 (struct sortstr.size, record_overlay_string)
19123 (struct sortstrlist.size, struct sortlist.used):
19124 Don't truncate size to int.
19125 (record_overlay_string): Check for size-calculation overflow.
19126 (init_buffer_once): Check at compile-time, not run-time.
19128 2011-06-22 Jim Meyering <meyering@redhat.com>
19130 Don't leak an XBM-image-sized buffer
19131 * image.c (xbm_load): Free the image buffer after using it.
19133 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19136 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19137 that Sun C diagnosed.
19138 * fns.c (secure_hash): Fix pointer signedness issue.
19139 * intervals.c (static_offset_intervals): New function.
19140 (offset_intervals): Use it.
19142 2011-06-21 Leo Liu <sdl.web@gmail.com>
19145 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19148 * fns.c (secure_hash): Rename from crypto_hash_function and change
19149 the first arg to accept symbols.
19150 (Fsecure_hash): New primitive.
19151 (syms_of_fns): New symbols.
19153 2011-06-20 Deniz Dogan <deniz@dogan.se>
19155 * process.c (Fset_process_buffer): Clarify return value in
19158 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19160 * dispnew.c (add_window_display_history): Use BVAR.
19162 * xdisp.c (debug_method_add): Use BVAR.
19163 (check_window_end, dump_glyph_matrix, dump_glyph)
19164 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19166 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19169 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19170 check till after the cache is created in init_frame_faces.
19172 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19174 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19176 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19178 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19179 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19180 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19182 Improve buffer-overflow checking (Bug#8873).
19183 * fileio.c (Finsert_file_contents):
19184 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19185 Remove the old (too-loose) buffer overflow checks.
19186 They weren't needed, since make_gap checks for buffer overflow.
19187 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19188 The old code merely checked for Emacs fixnum overflow, and relied
19189 on undefined (wraparound) behavior. The new code avoids undefined
19190 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19192 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19193 Tune. Don't use wider integers than needed. Don't use alloca.
19194 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19196 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19198 * insdel.c, lisp.h (buffer_overflow): New function.
19199 (insert_from_buffer_1, replace_range, replace_range_2):
19200 * insdel.c (make_gap_larger):
19201 * editfns.c (Finsert_char):
19202 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19204 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19206 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19208 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19210 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19211 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19213 * fileio.c: Don't assume EMACS_INT fits in off_t.
19214 (emacs_lseek): New static function.
19215 (Finsert_file_contents, Fwrite_region): Use it.
19216 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19218 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19220 * fns.c: Don't overflow int when computing a list length.
19221 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19222 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19223 truncation on 64-bit hosts. Check for QUIT every
19224 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19225 faster and is responsive enough.
19226 (Flength): Report an error instead of overflowing an integer.
19227 (Fsafe_length): Return a float if the value is not representable
19228 as a fixnum. This shouldn't happen except in contrived situations.
19229 (Fnthcdr, Fsort): Don't assume list length fits in int.
19230 (Fcopy_sequence): Don't assume vector length fits in int.
19232 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19233 (header_size, word_size): New constants.
19234 (allocate_vectorlike): Don't check size overflow here.
19235 (allocate_vector): Check it here instead, since this is the only
19236 caller of allocate_vectorlike that could cause overflow.
19237 Check that the new vector's length is representable as a fixnum.
19239 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19240 The previous code was bogus. For example, next_almost_prime (32)
19241 returned 39, which is undesirable as it is a multiple of 3; and
19242 next_almost_prime (24) returned 25, which is a multiple of 5 so
19243 why was the code bothering to check for multiples of 7?
19245 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19247 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19249 Variadic C functions now count arguments with ptrdiff_t.
19250 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19251 Back then I didn't know that the Emacs coding style prefers signed int.
19252 Also, in the meantime I found a few more instances where arguments
19253 were being counted with int, which may truncate counts on 64-bit
19254 machines, or EMACS_INT, which may be unnecessarily wide.
19255 * lisp.h (struct Lisp_Subr.function.aMANY)
19256 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19257 Arg counts are now ptrdiff_t, not size_t.
19258 All variadic functions and their callers changed accordingly.
19259 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19260 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19261 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19262 * callint.c (Fcall_interactively): Check arg count for overflow,
19263 to avoid potential buffer overrun. Use signed char, not 'int',
19264 for 'varies' array, so that we needn't bother to check its size
19265 calculation for overflow.
19266 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19267 * eval.c (apply_lambda):
19268 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19269 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19270 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19272 * callint.c (Fcall_interactively): Don't use index var as event count.
19274 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19275 * mem-limits.h (SIZE): Remove; no longer used.
19277 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19279 Remove unnecessary casts.
19280 * xterm.c (x_term_init):
19281 * xfns.c (x_set_border_pixel):
19282 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19283 These aren't needed now that we assume ANSI C.
19285 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19286 It's more likely to cause problems (due to unsigned overflow)
19289 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19291 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19293 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19295 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19297 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19299 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19301 GLYPH_CODE_FACE returns EMACS_INT, not int.
19302 * dispextern.h (merge_faces):
19303 * xfaces.c (merge_faces):
19304 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19305 Don't assume EMACS_INT fits in int.
19307 * character.h (CHAR_VALID_P): Remove unused parameter.
19308 * fontset.c, lisp.h, xdisp.c: All uses changed.
19310 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19312 * fns.c (concat): Minor tuning based on overflow analysis.
19313 This doesn't fix any bugs. Use int to hold character, instead
19314 of constantly refetching from Emacs object. Use XFASTINT, not
19315 XINT, for value known to be a character. Don't bother comparing
19316 a single byte to 0400, as it's always less.
19318 * floatfns.c (Fexpt):
19319 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19321 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19324 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19326 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19327 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19328 incorrectly succeed when S was a string, because 4294967386 was
19329 truncated before it was used.
19331 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19332 Otherwise, an out-of-range integer could cause undefined behavior
19335 * composite.c: Use int, not EMACS_INT, for characters.
19336 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19337 EMACS_INT, for values that are known to be in character range.
19338 This doesn't fix any bugs but is the usual style inside Emacs and
19339 may generate better code on 32-bit machines.
19341 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19342 This is for reasons similar to the recent CHAR_STRING fix.
19343 * charset.c (Fencode_char): Check that character arg is actually
19344 a character. Pass an int to ENCODE_CHAR.
19345 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19346 wider than 'int', as a compile-time check to prevent future regressions
19349 * character.c (char_string): Remove unnecessary casts.
19351 Make sure a 64-bit char is never passed to CHAR_STRING.
19352 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19353 by silently ignoring the top 32 bits, allowing some values
19354 that were far too large to be valid characters.
19355 * character.h: Include <verify.h>.
19356 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19357 arguments are no wider than unsigned, as a compile-time check
19358 to prevent future regressions in this area.
19360 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19361 (Fsubst_char_in_region):
19363 * xdisp.c (decode_mode_spec_coding):
19364 Adjust to CHAR_STRING's new requirement.
19365 * editfns.c (Finsert_char, Fsubst_char_in_region):
19366 * fns.c (concat): Check that character args are actually
19367 characters. Without this test, these functions did the wrong
19368 thing with wildly out-of-range values on 64-bit hosts.
19370 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19371 These casts should not be needed on 32-bit hosts, either.
19372 * keyboard.c (read_char):
19373 * lread.c (Fload): Remove casts to unsigned.
19375 * lisp.h (UNSIGNED_CMP): New macro.
19376 This fixes comparison bugs on 64-bit hosts.
19377 (ASCII_CHAR_P): Use it.
19378 * casefiddle.c (casify_object):
19379 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19380 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19381 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19382 * dispextern.h (FACE_FROM_ID):
19383 * keyboard.c (read_char): Use UNSIGNED_CMP.
19385 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19386 not to EMACS_INT, to avoid GCC warning.
19388 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19390 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19391 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19392 isn't needed on 32-bit machines.
19394 * buffer.c (Fgenerate_new_buffer_name):
19395 Use EMACS_INT for count, not int.
19396 (advance_to_char_boundary): Return EMACS_INT, not int.
19398 * data.c (Qcompiled_function): Now static.
19400 * window.c (window_body_lines): Now static.
19402 * image.c (gif_load): Rename local to avoid shadowing.
19404 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19405 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19406 * alloc.c (make_save_value): Integer argument is now of type
19407 ptrdiff_t, not int.
19408 (mark_object): Use ptrdiff_t, not int.
19409 * lisp.h (pD): New macro.
19410 * print.c (print_object): Use it.
19412 * alloc.c: Use EMACS_INT, not int, to count objects.
19413 (total_conses, total_markers, total_symbols, total_vector_size)
19414 (total_free_conses, total_free_markers, total_free_symbols)
19415 (total_free_floats, total_floats, total_free_intervals)
19416 (total_intervals, total_strings, total_free_strings):
19417 Now EMACS_INT, not int. All uses changed.
19418 (Fgarbage_collect): Compute overall total using a double, so that
19419 integer overflow is less likely to be a problem. Check for overflow
19420 when converting back to an integer.
19421 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19422 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19423 These were 'int' variables that could overflow on 64-bit hosts;
19424 they were never used, so remove them instead of repairing them.
19425 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19426 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19427 Previously, this ceilinged at INT_MAX, but that doesn't work on
19429 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19431 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19432 (allocate_vectorlike): Check for ptrdiff_t overflow.
19433 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19434 when a (possibly-narrower) signed value would do just as well.
19435 We prefer using signed arithmetic, to avoid comparison confusion.
19437 * alloc.c: Catch some string size overflows that we were missing.
19438 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19439 for convenience in STRING_BYTES_MAX.
19440 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19441 The definition here is exact; the one in lisp.h was approximate.
19442 (allocate_string_data): Check for string overflow. This catches
19443 some instances we weren't catching before. Also, it catches
19444 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19445 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19446 and ptrdiff_t and EMACS_INT are both 64 bits.
19448 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19449 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19450 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19452 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19454 * alloc.c (Fmake_string): Check for out-of-range init.
19456 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19458 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19460 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19462 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19463 xg_get_default_scrollbar_width.
19465 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19466 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19467 (style_changed_cb): Call update_theme_scrollbar_width and call
19468 x_set_scroll_bar_default_width and xg_frame_set_char_size for
19469 all frames (Bug#8505).
19470 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19471 Call gtk_window_set_resizable if HAVE_GTK3.
19472 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
19473 and height if HAVE_GTK3 (Bug#8505).
19474 (scroll_bar_width_for_theme): New variable.
19475 (update_theme_scrollbar_width): New function.
19476 (xg_get_default_scrollbar_width): Move code to
19477 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19478 (xg_initialize): Call update_theme_scrollbar_width.
19480 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19482 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19484 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19486 * frame.c (make_frame): Call other_buffer_safely instead of
19489 * window.c (temp_output_buffer_show): Call display_buffer with
19490 second argument Vtemp_buffer_show_specifiers and reset latter
19491 immediately after the call.
19492 (Vtemp_buffer_show_specifiers): New variable.
19493 (auto_window_vscroll_p, next_screen_context_lines)
19494 (Vscroll_preserve_screen_position): Remove leading asterisks from
19497 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
19499 Fix minor problems found by GCC 4.6.0 static checking.
19500 * buffer.c (Qclone_number): Remove for now, as it's unused.
19501 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
19502 (record_buffer): Remove unused local.
19503 * frame.c (other_visible_frames, frame_buffer_list): Now static.
19504 (set_frame_buffer_list): Remove; unused.
19505 * frame.h (other_visible_frames): Remove decl.
19506 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
19507 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
19508 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
19510 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
19511 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
19512 Define only if HAVE_GPM.
19513 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
19514 (update_hints_inhibit): Remove; never set. All uses removed.
19515 * widgetprv.h (emacsFrameClassRec): Remove decl.
19516 * window.c (delete_deletable_window): Now returns void, since it
19517 wasn't returning anything.
19518 (compare_window_configurations): Remove unused locals.
19519 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
19520 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
19521 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
19522 the same widths as pointers. This follows up on the 2011-05-06 patch.
19523 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
19524 * xterm.h: Likewise.
19525 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
19527 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
19529 * makefile.w32-in: Update dependencies.
19530 (LISP_H): Add lib/intprops.h.
19532 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
19534 * image.c (gif_load): Add animation frame delay to the metadata.
19535 (syms_of_image): Use DEFSYM. New symbol `delay'.
19537 2011-06-11 Martin Rudalics <rudalics@gmx.at>
19539 * window.c (delete_deletable_window): Re-add.

19993 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
19995 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
19997 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
19999 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20001 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
20002 in the current matrix if keep_current_p is non-zero.
20004 2011-06-04 Eli Zaretskii <eliz@gnu.org>
20006 * bidi.c (bidi_level_of_next_char): Fix last change.
20008 2011-06-03 Eli Zaretskii <eliz@gnu.org>
20010 Support bidi reordering of text covered by display properties.
20012 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
20013 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
20014 (bidi_cache_search, bidi_cache_iterator_state)
20015 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
20016 (bidi_level_of_next_char, bidi_move_to_visually_next):
20017 Support character positions inside a run of characters covered by a
20019 (bidi_paragraph_init, bidi_resolve_explicit_1)
20020 (bidi_level_of_next_char): Call bidi_fetch_char and
20021 bidi_fetch_char_advance instead of FETCH_CHAR and
20022 FETCH_CHAR_ADVANCE.
20023 (bidi_init_it): Initialize new members.
20024 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
20026 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
20027 instead of using explicit *_CHAR codes.
20028 (bidi_resolve_explicit, bidi_resolve_weak):
20029 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
20030 bidirectional text is supported only in multibyte buffers.
20031 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
20032 it to initialize the frame_window_p member of struct bidi_it.
20033 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
20034 (bidi_resolve_explicit, bidi_resolve_weak)
20035 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
20036 bidi_it->nchars is non-positive.
20037 (bidi_level_of_next_char): Don't try to lookup the cache for the
20038 next/previous character if nothing is cached there yet, or if we
20039 were just reseat()'ed to a new position.
20041 * xdisp.c (set_cursor_from_row): Set start and stop points
20042 according to the row's direction when priming the loop that looks
20043 for the glyph on which to display cursor.
20044 (single_display_spec_intangible_p): Function deleted.
20045 (display_prop_intangible_p): Reimplement to call
20046 handle_display_spec instead of single_display_spec_intangible_p.
20047 Accept 3 additional arguments needed by handle_display_spec.
20048 This fixes incorrect cursor motion across display property with complex
20049 values: lists, `(when COND...)' forms, etc.
20050 (single_display_spec_string_p): Support property values that are
20051 lists with the argument STRING its top-level element.
20052 (display_prop_string_p): Fix the condition for processing a
20053 property that is a list to be consistent with handle_display_spec.
20054 (handle_display_spec): New function, refactored from the
20055 last portion of handle_display_prop.
20056 (compute_display_string_pos): Accept additional argument
20057 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20058 value of a `display' property is a "replacing spec".
20059 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20060 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20061 the display property, but just return a value indicating whether
20062 the display property will replace the characters it covers.
20063 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20064 frame_window_p members of struct bidi_it.
20065 (compute_display_string_pos, compute_display_string_end):
20067 (push_it): Accept second argument POSITION, where pop_it should
20068 jump to continue iteration.
20069 (reseat_1): Initialize bidi_it.disp_pos.
20071 * keyboard.c (adjust_point_for_property): Adjust the call to
20072 display_prop_intangible_p to its new signature.
20074 * dispextern.h (struct bidi_it): New member frame_window_p.
20075 (bidi_init_it): Update prototypes.
20076 (display_prop_intangible_p): Update prototype.
20077 (compute_display_string_pos, compute_display_string_end):
20078 Declare prototypes.
20079 (struct bidi_it): New members nchars and disp_pos. ch_len is now
20082 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
20084 Malloc failure behavior now depends on size of allocation.
20085 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
20086 * lisp.h: Change signatures accordingly.
20087 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
20088 All callers changed. (Bug#8762)
20090 * gnutls.c: Use Emacs's memory allocators.
20091 Without this change, the gnutls library would invoke malloc etc.
20092 directly, which causes problems on non-SYNC_INPUT hosts, and which
20093 runs afoul of improving memory_full behavior. (Bug#8761)
20094 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20095 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20096 xfree instead of the default malloc, realloc, free.
20097 (Fgnutls_boot): No need to check for memory allocation failure,
20098 since xmalloc does that for us.
20100 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
20101 * category.c (hash_get_category_set):
20102 * ccl.c (ccl_driver):
20103 * charset.c (Fdefine_charset_internal):
20104 * charset.h (struct charset.hash_index):

20114 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
20115 (Fsxhash, Fgethash, Fputhash, Fmaphash):
20116 * image.c (make_image, search_image_cache, lookup_image)
20117 (xpm_put_color_table_h):
20118 * lisp.h (struct Lisp_Hash_Table):
20119 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20120 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20121 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20122 * alloc.c (allocate_vectorlike):
20123 Check for overflow in vector size calculations.
20124 * ccl.c (ccl_driver):
20125 Check for overflow when converting EMACS_INT to int.
20126 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20127 need to be updated by these changes.
20128 * fns.c (make_hash_table, maybe_resize_hash_table):
20129 Check for integer overflow with large hash tables.
20130 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20131 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20132 (SXHASH_REDUCE): New macro.
20133 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20134 Use it instead of discarding useful hash info with large hash values.
20135 (sxhash_float): New function.
20136 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20137 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20138 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20139 Rewrite to use FIXNUM_BITS, as this simplifies things.
20140 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20141 Adjust signatures to match updated version of code.
20142 (consing_since_gc): Now EMACS_INT, since a single hash table can
20143 use more than INT_MAX bytes.
20145 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20147 Make it possible to build with GCC-4.6+ -O2 -flto.
20149 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20151 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20153 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20154 Call minibuffer-inactive-mode.
20156 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20158 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20159 Update dependencies.
20161 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20163 * data.c (init_data): Remove code for UTS, this system is not
20166 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20168 Don't force ./temacs to start in terminal mode.
20170 * frame.c (make_initial_frame): Initialize faces in all cases, not
20171 only when CANNOT_DUMP is defined.
20172 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20174 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20176 * dispnew.c (add_window_display_history): Use const for the string
20177 pointer. Remove declaration, not needed.
20179 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20181 Use 'inline', not 'INLINE'.
20182 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20183 * alloc.c, fontset.c (INLINE): Remove.
20184 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20185 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20186 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20187 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20188 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20190 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20192 Make it possible to run ./temacs.
20194 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20195 syms_of_callproc does the same thing. Remove test for
20196 "initialized", do it in the caller.
20197 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20199 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20201 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20202 (read_minibuf): Use get_minibuffer.
20203 (syms_of_minibuf): Use DEFSYM.
20204 (Qmetadata): New var.
20205 * data.c (Qbuffer): Don't make it static.
20206 (syms_of_data): Use DEFSYM.
20208 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20210 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20211 (CCL_CODE_MIN): New macro.
20213 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20215 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20217 * eval.c (Qdebug): Now static.
20218 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20219 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20220 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20222 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20224 * image.c: Various fixes to ImageMagick code comments.
20225 (Fimagemagick_types): Doc fix.
20227 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20229 Minor fixes prompted by GCC 4.6.0 warnings.
20231 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20233 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20234 (x_clipboard_manager_save_all): Move extern decl to ...
20235 * xterm.h: ... here, so that it can be checked for consistency.
20237 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20239 * xselect.c (x_clipboard_manager_save_frame)
20240 (x_clipboard_manager_save_all): New functions.
20241 (Fx_clipboard_manager_save): Lisp function deleted.
20243 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20244 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20246 * xterm.h: Update prototype.
20248 2011-05-28 William Xu <william.xwl@gmail.com>
20250 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20251 exiting (Bug#8239).
20253 2011-05-28 Jim Meyering <meyering@redhat.com>
20255 Avoid a sign-extension bug in crypto_hash_function.
20256 * fns.c (to_uchar): Define.
20257 (crypto_hash_function): Use it to convert some newly-signed
20258 variables to unsigned, to avoid sign-extension bugs. For example,
20259 without this change, (md5 "truc") would evaluate to
20260 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20261 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20262 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20264 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20266 Integer overflow fixes.
20268 * dbusbind.c: Serial number integer overflow fixes.
20269 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20270 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20271 to hold a serial number that is too large for a fixnum.
20272 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20273 Check for serial numbers out of range. Decode any serial number
20274 that was so large that it became a float. (Bug#8722)
20276 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20277 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20278 Use XFASTINT rather than XUINT when numbers are nonnegative.
20279 (xd_append_arg, Fdbus_method_return_internal):
20280 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20281 arguments, check that Lisp number is nonnegative, rather than
20282 silently wrapping negative numbers around. (Bug#8722)
20283 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20286 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20288 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20290 ccl: Add integer overflow checks.
20291 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20292 (IN_INT_RANGE): New macros.
20293 (ccl_driver): Use them to check for integer overflow when
20294 decoding a CCL program. Many of the new checks are whether XINT (x)
20295 fits in int; it doesn't always, on 64-bit hosts. The new version
20296 doesn't catch all possible integer overflows, but it's an
20297 improvement. (Bug#8719)
20299 * alloc.c (make_event_array): Use XINT, not XUINT.
20300 There's no need for unsigned here.
20302 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20303 This follows up to the 2011-05-06 change that substituted uintptr_t
20304 for EMACS_INT. This case wasn't caught back then.
20306 Rework Fformat to avoid integer overflow issues.
20307 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20308 now (part of C89). Include <verify.h>.
20309 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20310 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20311 (Fformat): Avoid the prepass trying to compute sizes; it was only
20312 approximate and thus did not catch overflow reliably. Instead, walk
20313 through the format just once, formatting and computing sizes as we go,
20314 checking for integer overflow at every step, and allocating a larger
20315 buffer as needed. Keep track separately whether the format is
20316 multibyte. Keep only the most-recently calculated precision, rather
20317 than them all. Record whether each argument has been converted to
20318 string. Use EMACS_INT, not int, for byte and char and arg counts.
20319 Support field widths and precisions larger than INT_MAX. Avoid
20320 sprintf's undefined behavior with conversion specifications such as %#d
20321 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20322 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20323 formatting out-of-range floating point numbers with int
20324 formats. (Bug#8668)
20326 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20328 * data.c: Avoid integer truncation in expressions involving floats.
20329 * data.c: Include <intprops.h>.
20330 (arith_driver): When there's an integer overflow in an expression
20331 involving floating point, convert the integers to floating point
20332 so that the resulting value does not suffer from catastrophic
20333 integer truncation. For example, on a 64-bit host (* 4
20334 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20335 Do not rely on undefined behavior after integer overflow.
20337 merge count_size_as_multibyte, parse_str_to_multibyte
20338 * character.c, character.h (count_size_as_multibyte):
20339 Rename from parse_str_to_multibyte; all uses changed.
20340 Check for integer overflow.
20341 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20342 since it's now a duplicate of the other. This is more of
20343 a character than a buffer op, so better that it's in character.c.
20344 * fns.c, print.c: Adjust to above changes.
20346 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20348 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20350 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20352 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20353 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20354 (x_clipboard_manager_save): Now static.
20355 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20357 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20358 (crypto_hash_function): Now static.
20359 Fix pointer signedness problems. Avoid unnecessary initializations.
20361 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20363 * termhooks.h (Vselection_alist): Make it terminal-local.
20365 * terminal.c (create_terminal): Initialize it.
20367 * xselect.c: Support for clipboard managers.
20368 (Vselection_alist): Move to termhooks.h as terminal-local var.
20369 (LOCAL_SELECTION): New macro.
20370 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20371 (symbol_to_x_atom): Remove gratuitous arg.
20372 (x_handle_selection_request, lisp_data_to_selection_data)
20373 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20374 (x_own_selection, x_get_local_selection, x_convert_selection):
20375 New arg, specifying work frame. Use terminal-local Vselection_alist.
20376 (some_frame_on_display): Delete unused function.
20377 (Fx_own_selection_internal, Fx_get_selection_internal)
20378 (Fx_disown_selection_internal, Fx_selection_owner_p)
20379 (Fx_selection_exists_p): New optional frame arg.
20380 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20381 (x_handle_selection_clear): Don't treat other terminals with the
20382 same keyboard specially. Use the terminal-local Vselection_alist.
20383 (x_clear_frame_selections): Use Frun_hook_with_args.
20385 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20387 * xterm.h: Add support for those atoms.
20389 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20391 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20392 (converted_selections, conversion_fail_tag): New global variables.
20393 (x_selection_request_lisp_error): Free the above.
20394 (x_get_local_selection): Remove unnecessary code.
20395 (x_reply_selection_request): Args changed; handle arbitrary array
20396 of converted selections stored in converted_selections.
20397 Separate the XChangeProperty and SelectionNotify steps.
20398 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20399 (x_convert_selection): New function.
20400 (x_handle_selection_event): Simplify.
20401 (x_get_foreign_selection): Don't ignore incoming requests while
20402 waiting for an answer; this will fail when we implement
20403 SAVE_TARGETS, and seems unnecessary anyway.
20404 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20405 (Vx_sent_selection_functions): Doc fix.
20407 2011-05-26 Leo Liu <sdl.web@gmail.com>
20409 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20411 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20413 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20415 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20416 for fringe update if it has periodic bitmap.
20417 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20418 and fringe_bitmap_periodic_p.
20420 * fringe.c (get_fringe_bitmap_data): New function.
20421 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20422 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20423 row. Mark glyph row for fringe update if periodicity changed.
20425 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20426 for fringe update unless it has periodic bitmap.
20428 2011-05-25 Kenichi Handa <handa@m17n.org>
20430 * xdisp.c (get_next_display_element): Set correct it->face_id for
20431 a static composition.
20433 2011-05-24 Leo Liu <sdl.web@gmail.com>
20436 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20438 * fns.c (crypto_hash_function, Fsha1): New function.
20439 (Fmd5): Use crypto_hash_function.
20440 (syms_of_fns): Add Ssha1.
20442 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20444 * gnutls.c: Remove unused macros.
20445 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20446 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20447 Remove macros that are defined and never used.
20448 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20450 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20452 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20453 (Fx_get_selection_internal): Minor cleanup.
20454 (Fx_own_selection_internal): Rename arguments for consistency with
20457 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20459 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20461 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20463 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20465 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20467 * dispnew.c (scrolling_window): Don't exclude the case that the
20468 last enabled row in the desired matrix touches the bottom boundary.
20470 2011-05-21 Glenn Morris <rgm@gnu.org>
20472 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20473 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20474 and add some more files.
20476 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20478 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20479 report_file_error introduced by the change from 2011-05-07.
20481 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20483 * systime.h (Time): Define only if emacs is defined.
20484 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20485 where the include path doesn't have X11/X.h by default. See
20486 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20488 2011-05-20 Kenichi Handa <handa@m17n.org>
20490 * composite.c (find_automatic_composition): Fix previous change.
20492 2011-05-20 Glenn Morris <rgm@gnu.org>
20494 * lisp.mk: New file, split from Makefile.in.
20495 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20496 (shortlisp): Remove.
20497 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20499 2011-05-19 Glenn Morris <rgm@gnu.org>
20501 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20502 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20503 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20504 (lisp): Set the order to that of loadup.el.
20505 (shortlisp): Make it a copy of $lisp.
20506 (SOME_MACHINE_LISP): Remove.
20507 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20508 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20510 2011-05-18 Kenichi Handa <handa@m17n.org>
20512 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20513 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20514 (find_automatic_composition): Mostly rewrite for efficiency.
20516 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20518 * makefile.w32-in: Update dependencies.
20520 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20522 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20523 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20525 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20527 Fix some integer overflow issues, such as string length overflow.
20529 * insdel.c (count_size_as_multibyte): Check for string overflow.
20531 * character.c (lisp_string_width): Check for string overflow.
20532 Use EMACS_INT, not int, for string indexes and lengths; in
20533 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20534 the resulting string length overflows an EMACS_INT; instead,
20535 report a string overflow if no precision given. When checking for
20536 precision exhaustion, use a check that cannot possibly have
20537 integer overflow. (Bug#8675)
20538 * character.h (lisp_string_width): Adjust to new signature.
20540 * alloc.c (string_overflow): New function.
20541 (Fmake_string): Use it. This doesn't change behavior, but saves
20542 a few bytes and will simplify future changes.
20543 * character.c (string_escape_byte8): Likewise.
20544 * lisp.h (string_overflow): New decl.
20546 Fixups, following up to the user-interface timestamp change.
20547 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20548 for UI timestamps, instead of unsigned long.
20549 * msdos.c (mouse_get_pos): Likewise.
20550 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20551 * w32gui.h (Time): Define by including "systime.h" rather than by
20552 declaring it ourselves. (Bug#8664)
20554 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20555 * image.c (clear_image_cache): Likewise.
20557 * term.c (term_mouse_position): Don't assume time_t wraparound.
20559 Be more systematic about user-interface timestamps.
20560 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20561 and sometimes 'EMACS_UINT', to represent these timestamps.
20562 This change causes it to use 'Time' uniformly, as that's what X uses.
20563 This makes the code easier to follow, and makes it easier to catch
20564 integer overflow bugs such as Bug#8664.
20565 * frame.c (Fmouse_position, Fmouse_pixel_position):
20566 Use Time, not unsigned long, for user-interface timestamps.
20567 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20568 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20569 * keyboard.h (last_event_timestamp): Likewise.
20570 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20571 * menu.h (xmenu_show): Likewise.
20572 * term.c (term_mouse_position): Likewise.
20573 * termhooks.h (struct input_event.timestamp): Likewise.
20574 (struct terminal.mouse_position_hook): Likewise.
20575 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20576 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20577 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20578 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20579 what it was before.
20580 * menu.h, termhooks.h: Include "systime.h", for Time.
20582 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20583 Don't assume that the difference between two unsigned long values
20584 can fit into an integer. At this point, we know button_down_time
20585 <= event->timestamp, so the difference must be nonnegative, so
20586 there's no need to cast the result if double-click-time is
20587 nonnegative, as it should be; check that it's nonnegative, just in
20588 case. This bug is triggered when events are more than 2**31 ms
20589 apart (about 25 days). (Bug#8664)
20591 * xselect.c (last_event_timestamp): Remove duplicate decl.
20592 (x_own_selection): Remove needless cast to unsigned long.
20594 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20595 that always fit in int. Use a sentinel instead of a counter, to
20596 avoid a temp and to allay GCC's concerns about possible int overflow.
20597 * frame.h (struct frame): Use int for menu_bar_items_used
20598 instead of EMACS_INT, since it always fits in int.
20600 * menu.c (grow_menu_items): Check for int overflow.
20602 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20604 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20605 Before, the code was not consistent. These values cannot exceed
20606 2**31 - 1 so there's no need to make them unsigned.
20607 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20608 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20609 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20611 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20613 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20614 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20615 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20616 presumably because the widths might not match.
20618 * window.c (size_window): Avoid needless test at loop start.
20620 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20622 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20624 2011-05-12 Drew Adams <drew.adams@oracle.com>
20626 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20628 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20630 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20631 `width' to `bar_area_x' and `bar_area_width', respectively.
20632 (x_scroll_run): Take account of fringe background extension.
20634 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20635 Rename local vars `left' and `width' to `bar_area_x' and
20636 `bar_area_width', respectively.
20637 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20638 background extension.
20640 2011-05-10 Jim Meyering <meyering@redhat.com>
20642 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20644 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20646 * image.c (Finit_image_library): Return t for built-in image types,
20647 like pbm and xbm. (Bug#8640)
20649 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20651 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20653 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20655 * w32console.c (Fset_screen_color): Doc fix.
20656 (Fget_screen_color): New function.
20657 (syms_of_ntterm): Defsubr it.
20659 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20660 unlink the temporary file if Fcall_process didn't create it in the
20662 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20663 child process will be redirected to a file specified with `:file'.
20664 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20665 cue to call_process_cleanup not to close that handle.
20667 2011-05-07 Ben Key <bkey76@gmail.com>
20669 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20670 one of two shell specific rules, either bootstrap-temacs-CMD or
20671 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20672 to the previous implementation of the bootstrap-temacs rule.
20673 The bootstrap-temacs-CMD rule is similar to the previous
20674 implementation of the bootstrap-temacs rule except that it
20675 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20678 These changes, along with some changes to nt/configure.bat,
20679 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20680 earlier fix to add support for --cflags and --ldflags options
20681 that include quotes so that it works whether make uses cmd or
20684 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20686 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20687 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20689 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20690 a string. Handle both cases.
20691 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20692 (Fdbus_register_method): Use Qinvalid_function.
20694 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20696 * makefile.w32-in: Update dependencies.
20697 (LISP_H): Add inttypes.h and stdin.h.
20698 (PROCESS_H): Add unistd.h.
20700 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20702 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20703 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20705 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20707 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20709 * term.c (vfatal): Remove stray call to va_end.
20710 It's not needed and the C Standard doesn't allow it here anyway.
20712 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20713 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20715 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20718 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20720 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20722 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20724 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20726 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20728 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20729 * charset.c (Fdefine_charset_internal): Don't initialize
20730 charset.code_space[15]. The value was garbage, on hosts with
20731 32-bit int (Bug#8600).
20733 * lread.c (read_integer): Be more consistent with string-to-number.
20734 Use string_to_number to do the actual conversion; this avoids
20735 rounding errors and fixes some other screwups. Without this fix,
20736 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20737 (digit_to_number): Move earlier, for benefit of read_integer.
20738 Return -1 if the digit is out of range for the base, -2 if it is
20739 not a digit in any supported base. (Bug#8602)
20741 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20743 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20744 to match comment at start of function. This also removes a
20745 GCC warning about overflow in a 32+64-bit port.
20747 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20749 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20750 Reported by Stefan Monnier in
20751 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20752 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20753 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20755 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20756 (EMACS_UINTPTR): Likewise, with uintptr_t.
20758 * lisp.h: Prefer 64-bit EMACS_INT if available.
20759 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20760 on 32-bit hosts that have 64-bit int, so that they can access
20762 However, temporarily disable this change unless the temporary
20763 symbol WIDE_EMACS_INT is defined.
20765 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20767 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20768 This removes an assumption that EMACS_INT and long are the same
20769 width as pointers. The assumption is true for Emacs porting targets
20770 now, but we want to make other targets possible.
20771 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20772 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20773 In the rest of the code, change types of integers that hold casted
20774 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20775 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20776 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20777 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20778 No need to cast type when ORing.
20779 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20780 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20781 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20782 assume EMACS_INT is the same width as char *.
20783 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20784 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20785 Remove no-longer-needed casts.
20786 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20787 (xg_tool_bar_help_callback, xg_make_tool_item):
20788 Use EMACS_INTPTR to hold an integer
20789 that will be cast to void *; this can avoid a GCC warning
20790 if EMACS_INT is not the same width as void *.
20791 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20792 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20793 (current_message_1, set_message_1):
20794 Use a local to convert to proper width without a cast.
20795 * xmenu.c (dialog_selection_callback): Likewise.
20797 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20798 Also, don't assume VALBITS / RAND_BITS is less than 5,
20799 and don't rely on undefined behavior when shifting a 1 left into
20801 * lisp.h (get_random): Change signature to match.
20803 * lread.c (hash_string): Use size_t, not int, for hash computation.
20804 Normally we prefer signed values; but hashing is special, because
20805 it's better to use unsigned division on hash table sizes so that
20806 the remainder is nonnegative. Also, size_t is the natural width
20807 for hashing into memory. The previous code used 'int', which doesn't
20808 retain enough info to hash well into very large tables.
20809 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20811 * dbusbind.c: Don't possibly lose pointer info when converting.
20812 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20813 Use XPNTR rather than XHASH, so that the high-order bits of
20814 the pointer aren't lost when converting through void *.
20816 * eval.c (Fautoload): Don't double-shift a pointer.
20818 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20820 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20822 * gnutls.c (DEF_GNUTLS_FN):
20823 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20825 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20827 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20830 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20832 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20833 New version that can reserve upto 2GB of heap space.
20835 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20837 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20839 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20841 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20842 `gnutls_certificate_set_x509_key_file'.
20844 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

20901 * process.c: Include lisp.h before w32.h, not after.
20902 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20903 instead of gnutls_record_check_pending.
20905 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20907 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20909 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

20955 rather than `XVECTOR (FOO)->size'.
20957 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20958 inttypes.h, as a gnulib replacement is used if it not available in
20961 2011-04-21 Eli Zaretskii <eliz@gnu.org>

20973 charbuf for the composition carryover bytes.
20975 2011-04-21 Eli Zaretskii <eliz@gnu.org>

20980 %llo or %llx format is passed. (Bug#8545)
20982 * window.c (window_scroll_line_based): Use a marker instead of
20983 simple variables to record original value of point. (Bug#7952)
20985 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20986 produced by %s or %c overflows available buffer space. (Bug#8545)
20988 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20990 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20991 (SIZE_MAX): Move defn after all includes, as they might #define it.
20993 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20995 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20997 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20999 * keyboard.c (Qdelayed_warnings_hook): Define.
21000 (command_loop_1): Run `delayed-warnings-hook'
21001 if Vdelayed_warnings_list is non-nil.
21002 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21003 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21005 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21007 * doprnt.c (doprnt): Don't return value smaller than the buffer
21008 size if the message was truncated. (Bug#8545).
21010 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21012 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21013 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21015 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21017 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21019 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21021 * makefile.w32-in: Update dependencies.
21023 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21025 Improve `doprnt' and its usage. (Bug#8545)
21026 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21027 `format_end'. Remove support for %l as a conversion specifier.
21028 Don't use xrealloc. Improve diagnostics when the %l size modifier
21029 is used. Update the commentary.
21031 * eval.c (verror): Simplify calculation of size_t.
21033 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21036 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21038 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21041 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21043 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21044 This makes this file independent of the recent pseudovector change.
21046 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21048 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21050 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21051 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21052 Remove unused local.
21053 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21055 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21056 GCC 4.6.0 optimizes based on type-based alias analysis.
21057 For example, if b is of type struct buffer * and v of type struct
21058 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21059 != &v->size, and therefore "v->size = 1; b->size = 2; return
21060 v->size;" must therefore return 1. This assumption is incorrect
21061 for Emacs, since it type-puns struct Lisp_Vector * with many other
21062 types. To fix this problem, this patch adds a new type struct
21063 vectorlike_header that documents the constraints on layout of vectors
21064 and pseudovectors, and helps optimizing compilers not get fooled
21065 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21066 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21067 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21069 (XSETPVECTYPE): Rewrite in terms of new macro.
21070 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21071 This is a bit clearer, and further avoids the possibility of
21072 undesirable aliasing.
21073 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21074 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21075 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21076 since Lisp_Subr is a special case (no "next" field).
21077 (ASIZE): Now uses header.size rather than size.
21078 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21079 to avoid the hassle of writing XVECTOR (foo)->header.size.
21080 (struct vectorlike_header): New type.
21081 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21082 object, to help avoid aliasing.
21083 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21084 (SUBRP): Likewise, since Lisp_Subr is a special case.
21085 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21086 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21087 (struct Lisp_Hash_Table): Combine first two members into a single
21088 struct vectorlike_header member. All uses of "size" and "next" members
21089 changed to be "header.size" and "header.next".
21090 * buffer.h (struct buffer): Likewise.
21091 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21092 * frame.h (struct frame): Likewise.
21093 * process.h (struct Lisp_Process): Likewise.
21094 * termhooks.h (struct terminal): Likewise.
21095 * window.c (struct save_window_data, struct saved_window): Likewise.
21096 * window.h (struct window): Likewise.
21097 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21098 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21099 * buffer.c (init_buffer_once): Likewise.
21100 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21102 * process.c (Fformat_network_address): Use local var for size,
21105 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21107 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21108 * data.c (atof): Remove decl; no longer used or needed.
21109 (digit_to_number): Move to lread.c.
21110 (Fstring_to_number): Use new string_to_number function, to be
21111 consistent with how the Lisp reader treats infinities and NaNs.
21112 Do not assume that floating-point numbers represent EMACS_INT
21113 without losing information; this is not true on most 64-bit hosts.
21114 Avoid double-rounding errors, by insisting on integers when
21115 parsing non-base-10 numbers, as the documentation specifies.
21116 * lisp.h (string_to_number): New decl, replacing ...
21117 (isfloat_string): Remove.
21118 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21119 (read1): Do not accept +. and -. as integers; this
21120 appears to have been a coding error. Similarly, do not accept
21121 strings like +-1e0 as floating point numbers. Do not report
21122 overflow for integer overflows unless the base is not 10 which
21123 means we have no simple and reliable way to continue.
21124 Break out the floating-point parsing into a new
21125 function string_to_number, so that Fstring_to_number parses
21126 floating point numbers consistently with the Lisp reader.
21127 (digit_to_number): Move here from data.c. Make it static inline.
21128 (E_CHAR, EXP_INT): Remove, replacing with ...
21129 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21130 (string_to_number): New function, replacing isfloat_string.
21131 This function checks for valid syntax and produces the resulting
21132 Lisp float number too. Rework it so that string-to-number
21133 no longer mishandles examples like "1.0e+". Use strtoumax,
21134 so that overflow for non-base-10 numbers is reported only when
21135 there's no portable and simple way to convert to floating point.
21137 * textprop.c (set_text_properties_1): Rewrite for clarity,
21138 and to avoid GCC warning about integer overflow.
21140 * intervals.h (struct interval): Use EMACS_INT for members
21141 where EMACS_UINT might cause problems. See
21142 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21143 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21144 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21146 (offset_intervals): Tell GCC not to worry about length overflow
21147 when negating a negative length.
21149 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21150 (overrun_check_free): Likewise.
21152 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21153 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21156 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21157 (gnutls_make_error): Rename local to avoid shadowing.
21158 (gnutls_emacs_global_deinit): ifdef out; not used.
21159 (Fgnutls_boot): Use const for pointer to readonly storage.
21160 Comment out unused local. Fix pointer signedness problems.
21162 * lread.c (openp): Don't stuff size_t into an 'int'.
21163 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21164 about possible signed overflow.
21166 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21167 (GDK_KEY_g): Don't define if already defined.
21168 (xg_prepare_tooltip): Avoid pointer signedness problem.
21169 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21171 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21172 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21174 * xfns.c (Fx_window_property): Simplify a bit,
21175 to make a bit faster and to avoid GCC 4.6.0 warning.
21176 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21178 * fns.c (internal_equal): Don't assume size_t fits in int.
21180 * alloc.c (compact_small_strings): Tighten assertion a little.
21182 Replace pEd with more-general pI, and fix some printf arg casts.
21183 * lisp.h (pI): New macro, generalizing old pEd macro to other
21184 conversion specifiers. For example, use "...%"pI"d..." rather
21185 than "...%"pEd"...".
21186 (pEd): Remove. All uses replaced with similar uses of pI.
21187 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21188 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21189 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21190 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21191 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21192 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21193 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21195 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21196 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21197 * print.c (safe_debug_print, print_object): Likewise.
21198 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21200 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21201 avoiding the 0 flag, which is not portable.
21202 * process.c (Fmake_network_process): Use pI to avoid cast.
21203 * region-cache.c (pp_cache): Likewise.
21204 * xdisp.c (decode_mode_spec): Likewise.
21205 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21206 behavior on 64-bit hosts with printf arg.
21207 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21208 (x_stop_queuing_selection_requests): Likewise.
21209 (x_get_window_property): Don't truncate byte count to an 'int'
21212 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21213 here, since it parses constructs like leading '-' and spaces,
21214 which are not wanted; and it overflows with large numbers.
21215 Instead, simply match F[0-9]+, which is what is wanted anyway.
21217 * alloc.c: Remove unportable assumptions about struct layout.
21218 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21219 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21220 (allocate_vectorlike, make_pure_vector): Use the new macros,
21221 plus offsetof, to remove unportable assumptions about struct layout.
21222 These assumptions hold on all porting targets that I know of, but
21223 they are not guaranteed, they're easy to remove, and removing them
21224 makes further changes easier.
21226 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21227 This doesn't fix a bug but makes the code clearer.
21228 (string_overrun_cookie): Now const. Use initializers that
21229 don't formally overflow signed char, to avoid warnings.
21230 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21231 can cause Emacs to crash when string overrun checking is enabled.
21232 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21233 multiple of sizeof (EMACS_INT); it need not be, if
21234 alignof(EMACS_INT) < sizeof (EMACS_INT).
21235 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21237 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
21239 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
21241 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
21243 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
21244 supposed to be handshaking. (Bug#8556)
21245 Reported by Paul Eggert <eggert@cs.ucla.edu>.
21247 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
21249 * lisp.h (Qdebug): List symbol.
21250 * eval.c (Qdebug): Restore global linkage.
21251 * keyboard.c (debug-on-event): New variable.
21252 (handle_user_signal): Break into debugger when debug-on-event
21253 matches the current signal symbol.
21255 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
21257 * alloc.c (check_sblock, check_string_bytes)
21258 (check_string_free_list): Convert to standard C.
21260 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>

21818 * xfaces.c (face_at_string_position):
21819 Use FACE_SUITABLE_FOR_ASCII_CHAR_P, not FACE_SUITABLE_FOR_CHAR_P,

21988 Declare Lisp_Object Q* variables to be 'static' if not exported.
21989 This makes it easier for human readers (and static analyzers)
21990 to see whether these variables are used from other modules.

22004 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22006 Make Emacs functions such as Fatom 'static' by default.
22007 This makes it easier for human readers (and static analyzers)
22008 to see whether these functions can be called from other modules.
22009 DEFUN now defines a static function. To make the function external
22010 so that it can be used in other C modules, use the new macro DEFUE.

22016 Remove decls, since these functions are now static.
22017 (Funintern, Fget_internal_run_time): New decls, since these functions
22018 were already external.
22020 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

22028 Mark functions with DEFUE instead of DEFUN,
22029 if they are used in other modules.
22030 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22031 decls for now-static functions.

22068 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22070 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init

22073 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22075 * charset.c (Fclear_charset_maps): Use xfree instead of free.

22084 (overrun_check_free): Protoize.
22086 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22088 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22089 since callers should never pass a negative size.
22090 Change the signature to match that of plain 'read' and 'write'; see
22091 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22092 * lisp.h: Update prototypes of emacs_write and emacs_read.
22094 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22096 * xdisp.c (redisplay_window): Don't try to determine the character
22097 position of the scroll margin if the window start point w->startp
22098 is outside the buffer's accessible region. (Bug#8468)
22100 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22102 Fix write-region and its subroutines for buffers > 2GB.
22103 * fileio.c (a_write, e_write): Modify declaration of arguments and
22104 local variables to support buffers larger than 2GB.
22105 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22107 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22108 argument, local variables, and return value.
22110 * lisp.h: Update prototypes of emacs_write and emacs_read.
22112 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22114 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22116 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22118 Fix more problems found by GCC 4.6.0's static checks.
22120 * xdisp.c (vmessage): Use a better test for character truncation.
22122 * charset.c (load_charset_map): <, not <=, for optimization,
22123 and to avoid potential problems with integer overflow.
22124 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22125 * casetab.c (set_identity, shuffle): Likewise.
22126 * editfns.c (Fformat): Likewise.
22127 * syntax.c (skip_chars): Likewise.
22129 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22130 This also lets GCC 4.6.0 generate slightly better loop code.
22132 * callint.c (Fcall_interactively): <, not <=, for optimization.
22133 (Fcall_interactively): Count the number of arguments produced,
22134 not the number of arguments given. This is simpler and lets GCC
22135 4.6.0 generate slightly better code.
22137 * ftfont.c: Distingish more carefully between FcChar8 and char.
22138 The previous code passed unsigned char * to a functions like
22139 strlen and xstrcasecmp that expect char *, which does not
22140 conform to the C standard.
22141 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22142 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22143 char * when the C standard requires it.
22145 * keyboard.c (read_char): Remove unused var.
22147 * eval.c: Port to Windows vsnprintf (Bug#8435).
22148 Include <limits.h>.
22149 (SIZE_MAX): Define if the headers do not.
22150 (verror): Do not give up if vsnprintf returns a negative count.
22151 Instead, grow the buffer. This ports to Windows vsnprintf, which
22152 does not conform to C99. Problem reported by Eli Zaretskii.
22153 Also, simplify the allocation scheme, by avoiding the need for
22154 calling realloc, and removing the ALLOCATED variable.
22156 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22158 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22159 But keep the doprint source code for now, as we might revamp it
22160 and use it again (Bug#8435).
22161 * lisp.h (doprnt): Remove.
22162 * Makefile.in (base_obj): Remove doprnt.o.
22163 * deps.mk (doprnt.o): Remove.
22165 error: Print 32- and 64-bit integers portably (Bug#8435).
22166 Without this change, on typical 64-bit hosts error ("...%d...", N)
22167 was used to print both 32- and 64-bit integers N, which relied on
22168 undefined behavior.
22169 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22170 * lisp.h (error, verror): Mark as printf-like functions.
22171 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22172 Report overflow in size calculations when allocating printf buffer.
22173 Do not truncate output string at its first null byte.
22174 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22175 Truncate the output at a character boundary, since vsnprintf does not
22177 * charset.c (check_iso_charset_parameter): Convert internal
22178 character to string before calling 'error', since %c now has the
22180 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22181 overflow when computing char to be passed to 'error'. Do not
22182 pass Lisp_Object to 'error'; pass the integer instead.
22183 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22184 formatted with plain %d.
22186 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22188 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22190 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.

22200 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22201 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22202 return ssize_t not "int", and use size_t as the buffer length.
22203 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22204 * gnutls.h: Update declarations.
22205 * process.c (read_process_output): Use ssize_t, to match.

22212 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22214 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22215 Use unsigned char, to match FcChar8 type definition.
22217 * xterm.c (handle_one_xevent):
22218 * xmenu.c (create_and_show_popup_menu):
22219 * xselect.c (x_decline_selection_request)

22232 EMACS_INT. All callers changed.
22233 (pint2hrstr): Last argument is now EMACS_INT.

22251 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22252 (encode_invocation_designation): Last argument P_NCHARS is now
22254 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.

22279 (Qhelp_form_show): New var.
22280 (syms_of_keyboard): Use DEFSYM macro.
22282 * print.c (internal_with_output_to_temp_buffer): Function deleted.

22318 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22320 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22321 This avoids several warnings with gcc -Wstrict-overflow.
22322 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22323 directly, rather than having caller test rule sign. This avoids
22324 some unnecessary tests.
22325 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22326 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22327 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22329 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22330 (xfont_open): Avoid unnecessary tests.
22332 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22334 * composite.h, composite.c (composition_gstring_put_cache):

22338 breaking out part of COMPOSITION_DECODE_RULE.
22339 (COMPOSITION_DECODE_RULE): Use it.
22340 * composite.c (get_composition_id): Remove unused local vars,
22341 by using the new macro.
22343 * textprop.c (set_text_properties_1): Change while to do-while,
22344 since the condition is always true at first.
22346 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22347 (interval_deletion_adjustment): Return unsigned value.
22350 * process.c (list_processes_1, create_pty, read_process_output):

22366 * print.c (print_error_message): Avoid int overflow.
22368 * font.c (font_list_entities): Redo for clarity,
22369 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22371 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22372 (font_score): Avoid potential overflow in diff calculation.
22374 * fns.c (substring_both): Remove var that is set but not used.
22375 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22377 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22379 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22380 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22381 can always succeed if overflow has undefined behavior.
22383 * search.c (boyer_moore, wordify): Remove vars set but not used.
22384 (wordify): Omit three unnecessary tests.
22386 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22387 All callers changed. This avoids the need for an unused var.
22389 * casefiddle.c (casify_region): Remove var that is set but not used.
22391 * dired.c (file_name_completion): Remove var that is set but not used.
22393 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22395 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22396 (Finsert_file_contents): Remove unnecessary code checking fd.
22398 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22399 Check for integer overflow on size calculations.
22401 * buffer.c (Fprevious_overlay_change): Remove var that is set
22404 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22405 Remove vars that are set but not used.
22406 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22407 (timer_check_2): Mark vars as initialized.
22409 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22411 * image.c (lookup_image): Remove var that is set but not used.
22412 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22414 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22415 that are set but not used.
22417 * xfns.c (make_invisible_cursor): Don't return garbage
22418 if XCreateBitmapFromData fails (Bug#8410).
22420 * xselect.c (x_get_local_selection, x_handle_property_notify):
22421 Remove vars that are set but not used.
22423 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22424 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22426 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22427 Remove var that is set but not used.
22428 (scroll_bar_windows_size): Now size_t, not int.
22429 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22430 Check for overflow.

22433 (map_tty_color) [!defined MSDOS]: Likewise.
22435 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22437 * coding.c: Remove vars that are set but not used.

22441 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22442 (decode_coding_charset): Remove vars that are set but not used.
22444 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22445 that is set but not used.
22447 * print.c (print_object): Remove var that is set but not used.
22449 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22450 The gnulib version avoids calling malloc in the usual case,
22451 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22452 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22453 * filelock.c (current_lock_owner): Likewise.
22454 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22455 * sysdep.c: Include allocator.h, careadlinkat.h.
22456 (emacs_no_realloc_allocator): New static constant.
22457 (emacs_readlink): New function.
22458 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22459 ../lib/careadlinkat.h.
22461 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22463 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22464 first non-nil return value).

22478 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22479 and thereabouts. All callers changed.
22480 (get_per_char_metric): Remove parameter `f', unused since
22481 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22483 2011-04-02 Jim Meyering <meyering@redhat.com>
22485 do not dereference NULL upon failed strdup
22486 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22487 (ns_get_family): Likewise.
22489 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22491 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22493 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22495 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or

22515 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22517 * keyboard.c (eval_dyn): New fun.
22518 (menu_item_eval_property): Use it.

22522 * fns.c (concat, mapcar1): Accept byte-code-functions.
22524 * eval.c (Fsetq): Handle lexical vars.
22525 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22526 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22527 (FletX, Flet): Obey lexical binding.
22528 (Fcommandp): Handle closures.
22529 (Feval): New `lexical' arg.
22530 (eval_sub): New function extracted from Feval. Use it almost
22531 everywhere where Feval was used. Look up vars in lexical env.
22533 (Ffunctionp): Move from subr.el.
22534 (Ffuncall): Handle closures.
22535 (apply_lambda): Remove `eval_flags'.
22536 (funcall_lambda): Handle closures and new byte-code-functions.
22537 (Fspecial_variable_p): New function.
22538 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22539 but without exporting it to Lisp.
22541 * doc.c (Fdocumentation, store_function_docstring):
22542 * data.c (Finteractive_form): Handle closures.
22544 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22547 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22549 (exec_byte_code): New function extracted from Fbyte_code to handle new
22550 calling convention for byte-code-functions. Add new byte-codes.
22552 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22554 * alloc.c (Fmake_symbol): Init new `declared_special' field.

22563 (try_scrolling): Use it when setting scroll_limit.
22564 Limit scrolling to 100 screen lines.
22565 (redisplay_window): Even when falling back on "recentering",
22566 position point in the window according to scroll-conservatively,
22567 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22569 (try_scrolling): When point is above the window, allow searching
22570 as far as scroll_max, or one screenful, to compute vertical
22571 distance from PT to the scroll margin position. This prevents
22572 try_scrolling from unnecessarily failing when
22573 scroll-conservatively is set to a value slightly larger than the
22574 window height. Clean up the case of PT below the margin at bottom
22575 of window: scroll_max can no longer be INT_MAX. When aggressive
22576 scrolling is in use, don't let point enter the opposite scroll
22577 margin as result of the scroll.
22578 (syms_of_xdisp) <scroll-conservatively>: Document the
22579 threshold of 100 lines for never-recentering scrolling.

22587 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22588 (redisplay_internal): Remove parameter `preserve_echo_area',
22589 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22591 * indent.c (Fvertical_motion):
22592 * window.c (window_scroll_pixel_based, Frecenter):
22593 Don't pass `need_y_p' to `move_it_by_lines'.
22595 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22597 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22598 steal a few bits to be more compact.
22599 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22600 Remove unneeded casts.
22602 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22604 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22606 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22607 binding" message (bug#7967).

22613 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22614 Remove unused local var.
22616 * editfns.c (Fmessage_box): Remove unused local var.
22618 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22619 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22620 Omit unused local vars.
22621 * window.c (shrink_windows): Omit unused local var.
22622 * menu.c (digest_single_submenu): Omit unused local var.
22623 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22624 Omit unused local var.
22626 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22627 Don't assume string length fits in int.
22628 (keyremap_step, read_key_sequence): Use size_t for sizes.
22629 (read_key_sequence): Don't check last_real_key_start redundantly.
22631 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22632 instead of alloca (Bug#8344).
22634 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22635 (Fbacktrace_frame): Don't assume nframes fits in int.
22637 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22639 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22642 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22644 * cm.c (calccost): Turn while-do into do-while, for clarity.
22646 * keyboard.c (syms_of_keyboard): Use the same style as later
22647 in this function when indexing through an array. This also
22648 works around GCC bug 48267.
22650 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22652 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

22655 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22657 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22658 This avoids undefined behavior on integer overflow, and is a bit
22659 more convenient anyway since it is compared to a size_t variable.
22661 Variadic C functions now count arguments with size_t, not int.
22662 This avoids an unnecessary limitation on 64-bit machines, which
22663 caused (substring ...) to crash on large vectors (Bug#8344).
22664 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22665 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22666 All variadic functions and their callers changed accordingly.
22667 (struct gcpro.nvars): Now size_t, not int. All uses changed.
22668 * data.c (arith_driver, float_arith_driver): Likewise.
22669 * editfns.c (general_insert_function): Likewise.

22671 (internal_condition_case_n, run_hook_with_args, apply_lambda)
22672 (funcall_lambda, mark_backtrace): Likewise.
22673 * fns.c (concat): Likewise.
22674 * frame.c (x_set_frame_parameters): Likewise.
22675 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22676 0 if not found, not -1. All callers changed.
22678 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22679 (stack_copy_size): Now size_t, not int.
22680 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

22685 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22686 All callers changed.
22688 * lisp.h (multibyte_char_to_unibyte):
22689 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22690 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22691 * character.h (CHAR_TO_BYTE8):
22692 * cmds.c (internal_self_insert):
22693 * editfns.c (general_insert_function):
22694 * keymap.c (push_key_description):
22695 * search.c (Freplace_match):
22696 * xdisp.c (message_dolog, set_message_1): All callers changed.
22698 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
22700 * keyboard.c (safe_run_hook_funcall): New function.
22701 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22702 don't set the hook to nil, but remove the offending function instead.
22703 (Qcommand_hook_internal): Remove, unused.
22704 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22705 Vcommand_hook_internal.
22707 * eval.c (enum run_hooks_condition): Remove.
22708 (funcall_nil, funcall_not): New functions.
22709 (run_hook_with_args): Call each function through a `funcall' argument.
22710 Remove `cond' argument, now redundant.
22711 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
22712 (Frun_hook_with_args_until_failure): Adjust accordingly.
22713 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

22719 * print.c (strout): Remove parameter `multibyte', unused since
22720 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
22722 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
22723 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22724 All callers changed.
22726 * w32.c (_wsa_errlist): Use braces for struct initializers.
22728 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
22729 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
22730 All callers changed.
22731 (string_buffer_position): Likewise. Also, make static (it's never
22732 used outside xdisp.c).

22736 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
22737 All callers changed.
22739 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22741 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

22752 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
22754 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22756 * nsmenu.m (runDialogAt): Remove argument to timer_check.
22758 2011-03-27 Glenn Morris <rgm@gnu.org>

22761 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
22762 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
22763 Replace SIGTYPE with void everywhere.

22774 * w32.c (read_unc_volume): Use parameter `henum', instead of
22775 global variable `wget_enum_handle'.
22777 * keymap.c (describe_vector): Remove parameters `indices' and
22778 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

22793 * gtkutil.c (xg_maybe_add_timer):
22794 * keyboard.c (readable_events):
22795 * process.c (wait_reading_process_output):
22796 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
22798 * insdel.c (adjust_markers_gap_motion):
22799 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

22873 2011-03-23 Julien Danjou <julien@danjou.info>
22875 * term.c (Fsuspend_tty, Fresume_tty):
22876 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22877 * window.c (temp_output_buffer_show):
22878 * insdel.c (signal_before_change):
22879 * frame.c (Fhandle_switch_frame):
22880 * fileio.c (Fdo_auto_save):
22881 * emacs.c (Fkill_emacs):
22882 * editfns.c (save_excursion_restore):
22883 * cmds.c (internal_self_insert):
22884 * callint.c (Fcall_interactively):
22885 * buffer.c (Fkill_all_local_variables):
22886 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22888 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22889 unconditionally since it does the check itself.
22891 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22893 Fix more problems found by GCC 4.5.2's static checks.
22895 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22896 the first time through the loop, since we know p0 < p1 then.
22897 This also avoids a gcc -Wstrict-overflow warning.
22899 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22900 leading to a memory leak, possible in functions like
22901 load_charset_map_from_file that can allocate an unbounded number
22902 of objects (Bug#8318).
22904 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22905 that could (at least in theory) be that large.
22907 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22908 This is less likely to overflow, and avoids undefined behavior if
22909 overflow does occur. All callers changed. Use strtoul to scan
22910 for the unsigned long integer.
22911 (pint2hrstr): Simplify and tune code slightly.
22912 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

22922 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22925 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22927 * process.c (Fmake_network_process): Use socklen_t, not int,
22928 where POSIX says socklen_t is required in portable programs.
22929 This fixes a porting bug on hosts like 64-bit HP-UX, where
22930 socklen_t is wider than int (Bug#8277).
22931 (Fmake_network_process, server_accept_connection):
22932 (wait_reading_process_output, read_process_output):
22935 * process.c: Rename or move locals to avoid shadowing.
22936 (list_processes_1, Fmake_network_process):
22937 (read_process_output_error_handler, exec_sentinel_error_handler):
22938 Rename or move locals.
22939 (Fmake_network_process): Define label "retry_connect" only if needed.
22940 (Fnetwork_interface_info): Fix pointer signedness.
22941 (process_send_signal): Add cast to avoid pointer signedness problem.
22942 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22943 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22945 Make tparam.h and terminfo.c consistent.
22946 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22947 Include tparam.h instead, since it declares them.
22948 * cm.h (PC): Remove extern decl; tparam.h now does this.
22949 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22950 * terminfo.c: Include tparam.h, to check interfaces.
22951 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22952 (tparam): Adjust signature to match interface in tparam.h;
22953 this removes some undefined behavior. Check that outstring and len
22954 are zero, which they always are with Emacs.
22955 * tparam.h (PC, BC, UP): New extern decls.
22957 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22958 (xftfont_open): Rename locals to avoid shadowing.
22960 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22961 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22962 (OTF_TAG_SYM): Omit macro if not needed.
22963 (ftfont_list): Remove unused local.
22964 (get_adstyle_property, ftfont_pattern_entity):
22965 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22966 Rename locals to avoid shadowing.
22968 * xfont.c (xfont_list_family): Mark var as initialized.
22970 * xml.c (make_dom): Now static.
22972 * composite.c (composition_compute_stop_pos): Rename local to
22974 (composition_reseat_it): Remove unused locals.
22975 (find_automatic_composition, composition_adjust_point): Likewise.
22976 (composition_update_it): Mark var as initialized.
22977 (find_automatic_composition): Mark vars as initialized,
22978 with a FIXME (Bug#8290).
22980 character.h: Rename locals to avoid shadowing.
22981 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
22982 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
22983 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
22984 (BUF_DEC_POS): Be more systematic about renaming local temporaries
22985 to avoid shadowing.
22987 * textprop.c (property_change_between_p): Remove; unused.
22989 * intervals.c (interval_start_pos): Now static.
22991 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
22993 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
22994 Rename locals to avoid shadowing.
22996 * sound.c (wav_play, au_play, Fplay_sound_internal):
22997 Fix pointer signedness.
22998 (alsa_choose_format): Remove unused local var.
22999 (wav_play): Initialize a variable to 0, to prevent undefined
23000 behavior (Bug#8278).
23002 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23004 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23006 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23007 clobbering (Bug#8298).
23008 * sysdep.c (sys_subshell): Likewise.
23009 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23011 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23012 This should get cleaned up, so that child_setup has the
23013 same signature on all platforms.
23015 * callproc.c (call_process_cleanup): Now static.
23016 (relocate_fd): Rename locals to avoid shadowing.
23018 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23020 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23021 not to be necessary, and produces flickering.
23023 2011-03-20 Glenn Morris <rgm@gnu.org>
23025 * config.in: Remove file.
23027 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

23041 * xfaces.c (Fx_load_color_file):
23042 Read color file from absolute filename (bug#8250).
23044 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23046 * makefile.w32-in: Update dependencies.
23048 2011-03-17 Eli Zaretskii <eliz@gnu.org>

23108 instead of using an uninitialized var.
23109 (font_sort_entities): Mark var as initialized.
23111 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.

23128 * alloc.c (mark_backtrace): Move decl from here ...
23129 * lisp.h: ... to here, so that it can be checked.
23131 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
23132 (Fdefvar): Rewrite so as not to use empty "else".

23137 * callint.c (quotify_arg, quotify_args): Now static.
23138 (Fcall_interactively): Rename locals to avoid shadowing.

23145 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
23146 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
23147 some of which prompt warnings from gcc -Wbad-function-cast.
23148 (Fformat_time_string, Fencode_time, Finsert_char):
23149 (Ftranslate_region_internal, Fformat):
23150 Rename or remove local vars to avoid shadowing.

23177 (Fmemory_limit): Cast sbrk's returned value to char *.
23179 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23180 avoids undefined behavior in theory.
23182 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23184 Use functions, not macros, for up- and down-casing (Bug#8254).
23185 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23186 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23187 to use the following functions instead of these macros.
23188 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23189 EMACS_INT, since callers assume the returned value fits in int.
23190 (upcase1): Likewise, for UPCASE_TABLE.
23191 (uppercasep, lowercasep, upcase): New static inline functions.
23192 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

23198 (regex_compile, re_search_2, re_match_2_internal):
23199 Remove unused local vars.

23201 which gcc can warn about.
23202 (regex_compile, re_match_2_internal): Mark locals as initialized.
23203 (RETALLOC_IF): Define only if needed.
23204 (WORDCHAR_P): Likewise. This one is never needed, but is used
23205 only in a comment talking about a compiler bug, so put inside
23206 the #if 0 of that comment.
23207 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23208 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23211 * search.c (boyer_moore): Rename locals to avoid shadowing.

23226 Rename locals to avoid shadowing.
23227 (Fvertical_motion): Mark locals as initialized.
23229 * casefiddle.c (casify_object, casify_region): Now static.
23230 (casify_region): Mark local as initialized.

23234 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23235 New macros, so that the caller can use some names other than
23236 gcpro1, gcpro2, etc.
23237 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23239 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23240 argument, for consistency with GCPRO2_VAR, etc: it is now the
23241 prefix of the variable, not the variable itself. All uses
23243 * dired.c (directory_files_internal, file_name_completion):
23244 Rename locals to avoid shadowing.
23246 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23247 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23248 dired.c's scmp function, had undefined behavior.
23249 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23250 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23251 * buffer.h: ... to here, because these macros use current_buffer,
23252 and the new implementation with inline functions needs to have
23253 current_buffer in scope now, rather than later when the macros
23255 (downcase, upcase1): New static inline functions.
23256 (DOWNCASE, UPCASE1): Reimplement using these functions.
23257 This avoids undefined behavior in expressions like
23258 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23259 from race conditions in accessing the global variables
23260 case_temp1 and case_temp2.
23261 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23262 * lisp.h (case_temp1, case_temp2): Remove their decls.
23263 * character.h (ASCII_CHAR_P): Move from here ...
23264 * lisp.h: ... to here, so that the inline functions mentioned
23265 above can use them.
23267 * dired.c (directory_files_internal_unwind): Now static.
23269 * fileio.c (file_name_as_directory, directory_file_name):
23270 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
23272 (file_name_as_directory): Use const pointers when appropriate.
23273 (Fexpand_file_name): Likewise. In particular, newdir might
23274 point at constant storage, so make it a const pointer.
23275 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23276 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23278 (Fset_file_times, Finsert_file_contents, auto_save_error):
23279 Rename locals to avoid shadowing.

23282 (Ftry_completion, Fall_completions): Rename or remove locals
23283 to avoid shadowing.
23285 * marker.c (bytepos_to_charpos): Remove; unused.
23287 * lisp.h (verify_bytepos, count_markers): New decls,
23288 so that gcc does not warn that these functions aren't declared.
23290 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23291 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23292 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23293 (copy_text): Remove unused local var.
23295 * filelock.c (within_one_second): Now static.
23296 (lock_file_1): Rename local to avoid shadowing.
23298 * buffer.c (fix_overlays_before): Mark locals as initialized.
23299 (fix_start_end_in_overlays): Likewise. This function should be
23300 simplified by using pointers-to-pointers, but that's a different
23302 (switch_to_buffer_1): Now static.
23303 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23304 (report_overlay_modification): Rename locals to avoid shadowing.
23306 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
23307 Fix pointer signedness issue.
23308 (sys_subshell): Mark local as volatile if checking for lint,
23309 to suppress a gcc -Wclobbered warning that does not seem to be right.
23310 (MAXPATHLEN): Define only if needed.
23312 * process.c (serial_open, serial_configure): Move decls from here ...
23313 * systty.h: ... to here, so that they can be checked.
23315 * fns.c (get_random, seed_random): Move extern decls from here ...
23316 * lisp.h: ... to here, so that they can be checked.
23318 * sysdep.c (reset_io): Now static.
23319 (wait_for_termination_signal): Remove; unused.
23321 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
23322 (copy_keymap_item, append_key, push_text_char_description):
23324 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
23325 (DENSE_TABLE_SIZE): Remove; unused.
23326 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23327 (describe_map_tree):
23328 Rename locals to avoid shadowing.
23330 * keyboard.c: Declare functions static if they are not used elsewhere.
23331 (echo_char, echo_dash, cmd_error, top_level_2):
23332 (poll_for_input, handle_async_input): Now static.
23333 (read_char, kbd_buffer_get_event, make_lispy_position):
23334 (make_lispy_event, make_lispy_movement, apply_modifiers):
23335 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
23336 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
23337 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
23338 (read_key_sequence, read_char): Mark locals as initialized.

23352 if GCC considers string literals to be constants.
23354 * lisp.h (fatal_error_signal): Add decl, since it's exported.

23357 (xd_signature, xd_append_arg, xd_initialize):

23415 (BUF_PT_BYTE): Rewrite to handle indirect buffers (Bug#8219).
23416 These macros can no longer be used for assignment.
23418 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):

23474 2011-03-12 Paul Eggert <eggert@cs.ucla.edu>
23476 Improve quality of tests for time stamp overflow.
23477 For example, without this patch (encode-time 0 0 0 1 1
23478 1152921504606846976) returns the obviously-bogus value (-948597
23479 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
23480 reports time overflow. See
23481 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
23482 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
