109 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
110 when dealing with ElfW (Half) values, since they can exceed 2**31
111 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
112 (entry_address): Omit unused NUM arg. All uses changed.
114 2013-05-07 Juri Linkov <juri@jurta.org>

170 and dpyinfo->Xatom_net_current_desktop.
172 2013-05-06 Eli Zaretskii <eliz@gnu.org>
174 * xdisp.c (pos_visible_p): Use the special code for finding the
175 beginning of a display property or overlay for any "replacing"
176 display property, not just for display strings. This solves
177 incorrect reporting of position by posn-at-point. (Bug#14241)
179 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
181 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
182 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
183 Verify that ElfW (Half) fits in int.
184 (fatal): Use same signature as lisp.h.
185 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
186 configure and build with -DUNEXELF_DEBUG without worrying about
187 other modules that use DEBUG.
188 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
189 possibly-wide integers now uses it instead of plain fprintf.
190 (entry_address): New function, which avoids problems with 32-bit
191 overflow on 64-bit hosts.
192 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
193 (round_up): Don't assume the remainder fits in int.
194 (find_section): Use bool for boolean. Simplify debug code.
195 (unexec): Don't assume file sizes fit in int or size_t.
196 Omit unnecessary trailing newline in 'fatal' format.
197 Use strerror rather than outputting decimal error number.
198 Remove unused code when emacs is not defined;
199 this file relies on Emacs now.
200 Don't assume e_phnum and e_shnum are positive.
202 * regex.c: Fix problems when DEBUG is defined.
203 (extract_number, extract_number_and_incr): Define regardless of
204 whether DEBUG is defined; that's simpler and makes the code less
205 likely to go stale in the normal case when DEBUG is not defined.
206 Return int rather than taking an int * arg. All callers changed.
207 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
208 Remove, replacing with ...
209 (DEBUG_PRINT): New macro. All callers changed.
210 (DEBUG_COMPILES_ARGUMENTS): New macro.

215 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
216 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
217 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
218 Don't assume ptrdiff_t, size_t, and long are the same width as int.
219 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
220 This matters only when DEBUG is defined.
222 2013-05-05 Eli Zaretskii <eliz@gnu.org>
224 * xdisp.c (set_iterator_to_next): Set the
225 ignore_overlay_strings_at_pos_p flag only if we are _really_
226 iterating over an overlay string, as indicated by the
227 current.overlay_string_index member. (Bug#14306)
229 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
231 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
232 to where it is used, to avoid autorelease issues (Bug#14050).
234 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
236 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
237 * fileio.c (syms_of_fileio): Implement this.
238 * filelock.c (create_lock_file): If symbolic links don't work, so
239 we use a regular file as a lock file, do not fsync the lock file;
242 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
244 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.

253 Use parentheses to disambiguate last part of the condition.
255 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
256 assertion violations. (Bug#14062)
258 2013-05-01 David Reitter <david.reitter@gmail.com>
260 * nsfns.m (ns_tooltip): Initialize.
262 2013-04-28 Eli Zaretskii <eliz@gnu.org>

265 a newline unless it's a CR character. (Bug#14287)
267 2013-04-28 Dan Nicolaescu <dann@gnu.org>
269 * dispextern.h (struct face): Move enum face_underline_type

281 * callint.c (Fcall_interactively): Call `Qread_number' for
282 interactive code letter `n' instead of using duplicate code.
285 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
287 * systime.h (make_timeval): Declare as 'const'.
289 2013-04-27 Kenichi Handa <handa@gnu.org>
291 * font.c (font_open_entity): Always open a font of manageable
294 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
296 Port better to AIX (Bug#14258).
297 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,

308 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
309 Without this fix, "make distclean" leaves stamp-h1 behind.
311 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
313 * w32fns.c (w32_fullscreen_rect): New function to compute the
314 window rectangle for the given fullscreen mode.
315 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
316 longer tunes the window size. This keeps the window's edges flush
317 with the screen and allows the taskbar to hide itself in fullboth.
319 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
320 window decorations and uses the entire screen.
322 * w32term.h (w32_fullscreen_rect) Add prototype.

343 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
344 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
345 parentheses where appropriate.
347 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
349 * keyboard.c (timer_start_idle): Remove no-longer-used local.
351 2013-04-14 Eli Zaretskii <eliz@gnu.org>
353 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
354 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
355 Mention in the doc string that setting these variables takes
356 effect only after a call to set-window-buffer. (Bug#14200)
358 2013-04-13 Eli Zaretskii <eliz@gnu.org>
360 * indent.c (Fvertical_motion): Don't consider display strings on
361 overlay strings as display strings on the buffer position we
362 started from. This prevents vertical cursor motion from jumping
363 more than one line when there's an overlay string with a display
364 property at end of line.
365 Reported by Karl Chen <Karl.Chen@quarl.org> in
366 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

371 already selected (bug#14191).
373 2013-04-11 Eli Zaretskii <eliz@gnu.org>
375 * window.c (Fwindow_end): Test more flags, including the buffer's
376 last_overlay_modified flag, to determine whether the window's
377 display is really up-to-date. Prevents the function from
378 returning a stale value. (Bug#14170)
379 (Fwindow_line_height): Fix the test for up-to-date-ness of the
382 2013-04-10 Eli Zaretskii <eliz@gnu.org>
384 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
385 garbaged only if it is not already the top frame on its TTY.
386 This prevents flickering due to constant redrawing of TTY frames when
387 there are GUI frames open in the same session. (Bug#13864)
389 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
391 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
392 of marking the idle timers directly.
394 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
396 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
399 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>

418 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
421 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
423 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
424 This bug was introduced by my 2013-02-25 change that simplified
425 data_start configuration. Without this change, on GNU/Linux
426 an Emacs configured with --enable-profiling fails immediately
427 due to a profiler signal.
428 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
429 with these flags. On platforms where special flags are needed
430 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
431 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
432 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
434 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>

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

961 directories. If filename is nil, get directory name (Bug#13932).
962 Use getFilename and getDirectory.
963 (getFilename, getDirectory): New methods for EmacsSavePanel and
965 (ok:): In EmacsOpenPanel, if we can't choose directories, just return.

975 arg text_at_gap_tail. Cancel the code for handling it.
977 * coding.h (struct coding_system): New member eol_seen.
979 * coding.c (detect_ascii): New function.
980 (detect_coding): Set coding->head_ascii and coding->eol_seen only
981 when the source bytes are actually scanned. On detecting for
982 coding_category_utf_8_auto, call detect_ascii instead of scanning
983 source bytes directly.
984 (produce_chars): Call insert_from_gap with the new arg 0.
985 (encode_coding): Likewise.
986 (decode_coding_gap): Control ASCII optimization by the variable
987 disable_ascii_optimization instead of #ifndef .. #endif.
988 Deccode EOL format according to coding->eol_seen.
989 (syms_of_coding): Declare disable-ascii-optimization as a Lisp
992 * lisp.h (adjust_after_replace): Cancel externing it.

1005 (pp_cache): Put under ENABLE_CHECKING.
1007 2013-03-14 Eli Zaretskii <eliz@gnu.org>
1009 * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
1010 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
1012 (w32fullscreen_hook): If the frame is visible, reset
1013 f->want_fullscreen flag after changing the frame size. If the
1014 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
1017 2013-03-13 Daniel Colascione <dancol@dancol.org>
1019 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
1020 too so that these builds can use Cygwin's file conversion
1021 functions. (We've been building and linking cygw32.o all along
1022 and just not using it.)
1024 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1026 File synchronization fixes (Bug#13944).
1027 * Makefile.in (LIB_FDATASYNC): New macro.
1029 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
1030 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
1031 Don't worry about HAVE_FSYNC, since a substitute fsync is
1032 available if the system lacks one.
1033 (Fwrite_regin): Retry fsync if interrupted.
1035 2013-03-13 Eli Zaretskii <eliz@gnu.org>
1037 * w32term.c (w32_read_socket): If the Emacs frame is being
1038 activated, call w32fullscreen_hook, to make sure the new frame
1039 dimensions are in effect. (Bug#13937)
1041 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1043 * xdisp.c (init_iterator): Simplify because both character and byte
1044 positions are either specified or -1. Add eassert. Adjust comment.
1045 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1046 character and byte positions can be obtained from marker.
1048 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

1063 a function pointer type; the C Standard requires this.
1065 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
1066 Include <sys/param.h> unconditionally, as that works elsewhere and
1067 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1068 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
1071 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

1097 call ShellExecute in cygw32 builds.
1099 * w32fn.c (Fx_file_dialog): Use the above macros to simplify the
1100 common file dialog code.
1102 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
1103 can just use du like other systems.
1105 * coding.c (from_unicode_buffer): Declare.
1106 * coding.c (from_unicode_buffer): Implement.
1108 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

1152 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
1154 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
1155 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1156 from Elisp via unread-command-events.
1158 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1159 functions to mean "no change".
1161 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1163 region-cache.c, scroll.c, search.c: Use bool for booleans.
1164 * lisp.h (compile_pattern):

1169 (search_regs_saved, Fregexp_quote):
1170 Use bool for boolean.
1171 * region-cache.c (region_cache_forward, region_cache_backward):
1172 Fix comments to match code: these functions return int, not boolean.
1174 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1176 * search.c (find_newline): Accept start and end byte positions
1177 as arguments and allow -1 if not known.
1178 (find_newline_no_quit): Likewise for start position.
1179 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
1180 * bidi.c (bidi_find_paragraph_start): Pass byte position to
1181 find_newline_no_quit, thus eliminating CHAR_TO_BYTE.
1182 * editfns.c (Fconstrain_to_field): Break long line.
1183 Adjust call to find_newline.
1184 * indent.c (vmotion): Adjust calls to find_newline_no_quit.

1188 (get_visually_first_element, move_it_vertically_backward): Likewise.
1189 Obtain byte position from the display iterator, where appropriate.
1191 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1193 print.c, process.c: Use bool for booleans.
1194 * lisp.h (wait_reading_process_output):
1195 * print.c (print_output_debug_flag, PRINTDECLARE, printchar)
1196 (strout, debug_output_compilation_hack, float_to_string, print)

1209 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1211 * bidi.c (bidi_fetch_char): Swap first and second arguments
1212 to match other functions accepting character and byte positions.
1214 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
1215 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
1216 when you need just to move to the previous buffer position.
1217 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1219 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1232 Adjust comments, style and calls to compute_motion.
1233 (Fvertical_motion): Adjust call to vmotion.
1234 * window.c (Fdelete_other_windows_internal): Record window start
1235 byte position and adjust call to vmotion.
1236 (window_scroll_line_based): Likewise with call to compute_motion.
1238 (Frecenter): Adjust calls to vmotion.
1240 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
1242 * lisp.h (list2i, list3i): New functions.
1243 (list4i): Move from window.c and make LISP_INLINE.
1244 * editfns.c (make_lisp_time):
1245 * fns.c (Flocale_info):
1246 * keyboard.c (parse_modifiers):
1247 * xterm.c (x_ewmh_activate_frame): Use list2i.

1256 2013-03-06 Eli Zaretskii <eliz@gnu.org>
1258 * search.c (find_newline_no_quit): Rename from find_next_newline.
1261 * lisp.h (find_newline_no_quit): Rename prototype.
1263 * xdisp.c (back_to_previous_line_start)

1265 (move_it_vertically_backward): Callers of find_newline_no_quit changed.
1266 * indent.c (vmotion): Callers of find_newline_no_quit changed.
1267 * bidi.c (bidi_find_paragraph_start): Callers of
1268 find_newline_no_quit changed.

1273 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1275 Coding system support cleanup and minor refactoring.
1276 * coding.h (enum coding_result_code): Remove
1277 CODING_RESULT_INCONSISTENT_EOL and CODING_RESULT_INSUFFICIENT_MEM.
1278 (toplevel): Remove unused CODING_MODE_INHIBIT_INCONSISTENT_EOL.
1279 (CODING_MODE_LAST_BLOCK, CODING_MODE_SELECTIVE_DISPLAY)
1280 (CODING_MODE_DIRECTION, CODING_MODE_FIXED_DESTINATION)
1281 (CODING_MODE_SAFE_ENCODING): Rearrange bit values.

1287 (ALLOC_CONVERSION_WORK_AREA): Use SAFE_ALLOCA.
1288 (decode_coding, encode_coding): Add USE_SAFE_ALLOCA and SAFE_FREE.
1289 (decode_coding_object): Simplify since xrealloc never returns NULL.
1292 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1294 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1295 * sysdep.c (list_system_processes)
1296 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1297 Make it a stub in this case; otherwise the build might fail,
1298 and this code hasn't been tested on such hosts anyway.
1299 Problem reported by Nelson H. F. Beebe in
1300 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1301 and analyzed by Jérémie Courrèges-Anglas in
1302 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1304 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1306 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1307 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1308 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1309 * bidi.c (bidi_find_paragraph_start): Likewise.
1310 * indent.c (vmotion): Likewise.
1312 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1314 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1315 * filelock.c: Include <c-ctype.h>.
1316 (MAX_LFINFO): New top-level constant.
1317 (lock_info_type): Remove members pid, boot_time. Add members at,
1318 dot, colon. Change user member to be the entire buffer, not a
1319 pointer. This allows us to handle the case where a foreign
1320 pid or boot time exceeds the local range. All uses changed.
1321 (LINKS_MIGHT_NOT_WORK): New constant.
1322 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1323 (defined_WINDOWSNT): Remove.
1324 (MAKE_LOCK_NAME, file_in_lock_file_name):
1325 Always use .#FILE (not .#-FILE) for the file lock,
1326 even if it is a regular file.
1327 (rename_lock_file): New function.
1328 (create_lock_file): Use it.
1329 (create_lock_file, read_lock_data):
1330 Prefer a symbolic link for the lock file, falling back on a
1331 regular file if symlinks don't work. Do not try to create
1332 symlinks on MS-Windows, due to security hassles. Stick with
1333 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1334 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1335 host may be using a Windowsish file system, and cannot use
1336 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1337 doesn't work. Don't fail merely because of a symlink-contents
1338 length limit in the current file system; fall back on regular
1339 files. Increase the symlink contents length limit to 8 KiB, this
1340 should be big enough for any real use and doesn't crunch the
1342 (create_lock_file, lock_file_1, read_lock_data):
1343 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1344 (lock_file_1): Return error number, not bool. All callers changed.
1345 (ELOOP): New macro, if not already defined.
1346 (read_lock_data): Return size of lock file contents, not Lisp object.
1347 All callers changed. Handle a race condition if some other process
1348 replaces a regular-file lock with a symlink lock or vice versa,
1349 while we're trying to read the lock.
1350 (current_lock_owner): Parse contents more carefully, to help avoid
1351 confusing a regular-file lock with some other application's use
1352 of the file. Check for lock file contents being too long, or
1353 not parsing correctly.
1354 (current_lock_owner, lock_file):
1355 Allow foreign pid and boot times that exceed the local range.
1356 (current_lock_owner, lock_if_free, lock_file):
1357 Simplify allocation of lock file contents.
1358 * w32.c (sys_rename_replace): New function, containing most of
1359 the contents of the old sys_rename.
1360 (sys_rename): Use it.
1361 (fchmod): New dummy function.
1362 * w32.h (sys_rename_replace, fchmod): New decls.
1364 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1366 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1367 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1368 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1369 <dmantipov@yandex.ru>.
1371 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1373 * composite.c (get_composition_id, fill_gstring_header):
1374 Use make_uninit_vector where appropriate.
1375 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1376 * xselect.c (clean_local_selection_data): Likewise.
1378 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1380 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1381 * image.c (imagemagick_load_image): Calculate height and width
1382 after flattening the image, not before.
1384 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1386 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1387 * ftfont.c (ftfont_shape_by_flt): Likewise.
1388 * w32uniscribe.c (uniscribe_shape): Likewise.
1390 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1392 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1393 The old approach, which fell back on DIR/.#FILE.0 through
1394 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1395 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1396 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1397 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1398 because the locking mechanism was never reliable in that case).
1399 This patch fixes this and other bugs discovered by a code
1400 inspection that was prompted by
1401 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1402 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1403 to avoid interoperability problems between the MS-Windows and
1404 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1405 instances of Emacs now ignore each others' locks.
1406 * filelock.c (defined_WINDOWSNT): New constant.
1407 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1408 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1409 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1410 regular files on MS-Windows hosts.
1411 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1412 Use SAFE_ALLOCA to avoid problems with long file names.
1413 (MAX_LFINFO): Now a local constant, not a global macro.
1414 (IS_LOCK_FILE): Remove.
1415 (lock_file_1): Don't inspect errno if symlink call succeeds;
1416 that's not portable.
1417 (lock_file): Document that this function can return if lock
1419 (lock_file): Don't access freed storage.
1421 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

1427 * textprop.c: Use bool for booleans.
1428 (validate_interval_range, Fadd_text_properties)
1429 (Fremove_text_properties): Prefer bool to int when either works.
1431 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1433 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1434 If the interval tree changes as a side effect of calling
1435 modify_region, re-do processing starting from the call to
1436 validate_interval_range. (Bug#13743)
1438 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1440 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].

1445 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1446 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1447 access to the lock file until it is written and closed.

1462 Minor textprop integer cleanup.
1463 * intervals.h, textprop.c (add_text_properties_from_list):
1464 Return void, not int, since nobody uses the return value.
1465 * textprop.c (validate_plist, add_properties, remove_properties)
1466 (Fadd_text_properties):
1467 Don't assume list length fits in int.
1468 (interval_has_all_properties, interval_has_some_properties)
1469 (interval_has_some_properties_list, add_properties, remove_properties)

1479 Implement CLASH_DETECTION for MS-Windows.
1481 * filelock.c [WINDOWSNT]: Include w32.h.

1483 function of that name. Up-case the macro arguments.
1484 (IS_LOCK_FILE): New macro.
1485 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1486 (create_lock_file): New function, with body extracted from

1489 the lock information as its contents.
1490 (read_lock_data): New function, on Posix platforms just calls
1492 [WINDOWSNT]: Read the lock info from the file.
1493 (current_lock_owner): Call read_lock_data instead of calling
1494 emacs_readlinkat directly.
1495 (lock_file) [WINDOWSNT]: Run the file name through
1498 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1499 just check if the process by that PID exists.
1501 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1502 also present, as doing so will fail to error out if the file
1505 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1507 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1508 (Fremove_list_of_text_properties): Skip all of the intervals in
1509 the region between START and END that already have resp. don't
1510 have the requested properties, not just the first one.
1511 Add assertions that the loop afterwards always modifies the
1512 properties. (Bug#13743)
1514 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1516 * callint.c (Fcall_interactively): Use the right lexical environment

1525 (START_FILES): Remove. All uses removed.
1526 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
1527 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
1528 (buildobj.h): Use it.
1529 ($(ALLOBJS)): Depend on globals.h.
1530 (temacs$(EXEEXT)): Use $(ALLOBJS).
1531 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1532 * deps.mk (vm-limit.o):
1533 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
1534 Do not depend on mem-limits.h.
1535 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
1536 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)

1542 * vm-limit.c: Move most of mem-limits.h's contents here.
1543 (data_start): New decl. It's OK if this is approximate,
1544 so simplify-away some unnecessary exactness.
1545 (POINTER): Remove; all uses removed.
1546 (data_space_start): Now char *, to avoid casts.
1547 (exceeds_lisp_ptr): New function, replacing the old
1548 EXCEEDS_LISP_PTR macro. All uses changed.
1549 (check_memory_limits): Simplify and remove casts.
1550 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

1555 * xdisp.c (set_message): Only check for debug-on-message if STRING
1556 is a string. (Bug#13797)

1560 Fix regression introduced by July 10 filelock.c patch.
1561 * filelock.c (fill_in_lock_file_name): Fix crash caused by the
1562 2012-07-10 patch to this file. Reported by Eli Zaretskii in
1563 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
1564 and diagnosed by Andreas Schwab in
1565 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
1567 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1569 Assume C89 or better.
1570 * ralloc.c (SIZE, POINTER, NIL):
1571 * vm-limit.c (POINTER):
1572 Remove, replacing all uses with C89 equivalents. These old
1573 symbols were present only for porting to pre-C89 platforms.
1575 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1577 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1578 This avoids warning messages reported as part of Bug#13546.
1580 2013-02-21 Ken Brown <kbrown@cornell.edu>
1582 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
1584 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
1586 * sheap.c (report_sheap_usage): Prefer message1_nolog.
1588 * keyboard.c (Qcommand_execute): New var.
1589 (command_loop_1, read_char): Use it.
1590 (Fcommand_execute): Remove, replace by an Elisp implementation.

1593 2013-02-19 Daniel Colascione <dancol@dancol.org>
1595 * sheap.c (report_sheap_usage): Use message, not message1, so
1596 that we don't try to create a buffer while we're in the middle
1597 of dumping Emacs. Explain why.
1599 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1601 * search.c (find_newline): Return byte position in bytepos.
1603 (find_next_newline_no_quit, find_before_next_newline):
1604 Add bytepos argument.
1605 * lisp.h (find_newline, find_next_newline_no_quit)

1611 (get_visually_first_element, move_it_vertically_backward):
1612 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
1614 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1616 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1617 resources were not orderly released.
1619 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1621 * xdisp.c (x_draw_vertical_border): For a window that is neither
1622 the leftmost nor the rightmost, redraw both the left and the right
1623 vertical borders. (Bug#13723)

1643 2013-02-16 Eli Zaretskii <eliz@gnu.org>
1645 * w32.c (sys_chown): Remove unused function.
1647 * w32term.c <input_signal_count>: Declare 'volatile'
1648 unconditionally. (Bug#9066)
1650 * w32.c (set_errno): Reset h_errno and don't set it to any other
1651 value. Set errno instead.
1652 (check_errno): Reset h_errno.
1653 (sys_socket, socket_to_fd, sys_bind, sys_connect)
1654 (sys_gethostname, sys_getservbyname, sys_getpeername)
1655 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1656 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
1658 (sys_gethostbyname): Set h_errno only errors detected.
1660 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1662 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
1664 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1666 * keyboard.c (read_char): Fix calculation of auto-save time out
1667 when auto-save-timeout is less than 4. (Bug#13720)
1669 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1670 time. Improve diagnostics in DebPrint. (Bug#13546)

1676 make sure errno is set to an appropriate value. (Bug#13546)
1677 (socket_to_fd): Add assertion against indexing fd_info[] with a
1678 value that is out of bounds.
1679 (sys_accept): If fd is negative, do not set up the child_process
1680 structure for reading.
1682 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1684 * composite.c (fill_gstring_header): Remove useless prototype.

1691 (get_overlay_arrow_glyph_row, display_mode_element):
1692 (decode_mode_spec_coding, message3):
1693 * xfaces.c (face_at_string_position): Use bool for booleans.
1696 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1698 Fix AIX port (Bug#13650).
1699 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1700 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1701 was #undeffed earlier, so it cannot be used as a macro here.
1702 Use the constant and not the macro.
1704 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1706 * w32proc.c (new_child): If no vacant slots are found in
1707 child_procs[], make another pass looking for slots whose process
1708 has exited or died. (Bug#13546)
1710 * w32.c (sys_pipe): When failing due to file descriptors above
1711 MAXDESC, set errno to EMFILE.
1712 (_sys_read_ahead): Update cp->status when failing to read serial
1713 communications input, so that the status doesn't stay at
1714 STATUS_READ_IN_PROGRESS. (Bug#13546)
1716 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1718 * gtkutil.c (tb_size_cb): New function.
1719 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1721 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1723 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1726 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1728 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1730 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>
1732 * font.c (font_range): Add pos_byte argument. Adjust comment
1733 and break long line.
1734 * font.h (font_range): Adjust prototype.
1735 * composite.c (autocmp_chars): Pass byte position to font_range.
1736 Break long line. Remove useless prototype and format comment.
1738 2013-02-13 Glenn Morris <rgm@gnu.org>
1740 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1742 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1744 Improve AIX port some more (Bug#13650).
1745 With this, it should be as good as it was in 23.3, though it's
1746 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1747 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1748 * unexaix.c (start_of_text): Remove.
1749 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1750 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1751 (orig_load_scnptr, orig_data_scnptr):
1752 Now off_t, not long, since they are file offsets.
1753 (make_hdr): Use _data, not start_of_data ().
1754 This is the key part of the fix.
1755 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1756 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1758 * pre-crt0.c (data_start): Initialize to 1.
1759 This ports to compilers that optimize the external declaration
1760 'int x = 0;' as if it were 'int x;' to shrink the executable.
1762 Improve AIX port (Bug#13650).
1763 This doesn't fix the bug, but it makes progress: Emacs builds now.
1764 * unexaix.c: Include inttypes.h, stdarg.h.
1765 (report_error, report_error_1): Mark as _Noreturn.
1766 (report_error): Don't report the wrong errno.
1767 (report_error_1): Now varargs. All callers changed.
1768 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1769 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1770 (write_ptr): Use %p to print address rather than %lx and a cast
1771 to unsigned long. Grow buffer a bit, to be safer.
1773 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1775 * bidi.c (bidi_resolve_neutral): After finding the next
1776 non-neutral character, accept NEUTRAL_ON type as well, because
1777 directional control characters, such as LRE and RLE, have their
1778 type converted to that by bidi_resolve_weak. This avoids aborts
1779 when LRE/RLE follows a run of neutrals.
1780 (bidi_move_to_visually_next): Assert that return value of
1781 bidi_peek_at_next_level is non-negative. Negative values will
1784 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1786 Minor getenv-related fixes.
1787 * callproc.c (Fcall_process_region) [!DOS_NT]:
1788 Avoid unnecessary duplicate call to getenv.
1789 * callproc.c (init_callproc):
1790 * dispnew.c (init_display):
1791 * sysdep.c (sys_subshell):
1792 Omit unnecessary cast of getenv or egetenv.
1794 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1796 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1797 Update dependencies.
1799 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1801 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1803 (display_line): Set w->region_showing to the value of
1804 it->region_beg_charpos, not to -1. This fixes redisplay
1805 optimization when cursor is moved up after M->. (Bug#13623)
1807 (try_scrolling): Scroll text up more if point is too close to ZV
1808 and inside the scroll margin. This makes sure point is moved
1809 outside the scroll margin in these cases.
1811 * window.h (struct window): region_showing can no longer be
1814 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1816 Tune by using memchr and memrchr.
1817 * doc.c (Fsnarf_documentation):
1818 * fileio.c (Fsubstitute_in_file_name):
1819 * search.c (find_newline, scan_newline):
1820 * xdisp.c (pos_visible_p, display_count_lines):
1821 Use memchr and memrchr rather than scanning byte-by-byte.
1822 * search.c (find_newline): Rename from scan_buffer.
1823 Omit first arg TARGET, as it's always '\n'. All callers changed.
1825 Clean up read_key_sequence a tiny bit more.
1826 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1827 (read_key_sequence): Remove unused locals.
1829 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1831 Clean up read_key_sequence a bit; reread active keymaps after first event.
1832 * keyboard.c (read_char, read_char_x_menu_prompt)
1833 (read_char_minibuf_menu_prompt):
1834 Replace nmaps+maps with a single `map' arg.
1835 (follow_key): Operate on a single map.
1836 (active_maps): New function.
1837 (test_undefined): Also return true for nil bindings.
1838 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1839 a single (composed) keymap. Remember `first_event' to choose the right
1840 set of active keymaps. Recompute the set of keymaps after receiving
1841 the first event. Remove GOBBLE_FIRST_EVENT.
1842 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1843 * keyboard.h (read_char): Update declaration.
1844 * lread.c (read_filtered_event): Adjust call to read_char.
1846 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1848 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1849 Don't use the limitation on backwards movement when lines are truncated
1850 in the window. (Bug#13675)
1852 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1854 * marker.c (set_marker_internal): If desired position is passed
1855 as a marker, avoid call to buf_charpos_to_bytepos.
1856 * window.c (Fset_window_point): Omit redundant type checking.
1857 (Fset_window_start): Likewise. Format comment.
1858 (window_scroll_pixel_based): Use set_marker_restricted_both
1859 with character and byte positions obtained from an iterator.
1860 (Fset_window_configuration): Use set_marker_restricted_both.
1861 * xdisp.c (message_dolog): Likewise.
1863 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1865 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1866 When text lines are longer than window's screen lines, don't move back
1867 too far. This speeds up some redisplay operations. (Bug#13675)
1869 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1871 * syntax.c (scan_sexps_forward): Fix byte position calculation

1883 (sxhash_float): Return EMACS_UINT, for consistency with the other
1885 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1886 non-static inline function and therefore can't use static vars.
1887 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1888 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1889 with the other hash functions.
1891 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1893 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1894 XXXXXX part of the temporary file pattern is not downcased even
1895 when w32-downcase-file-names is non-nil. (Bug#13661)
1897 * xdisp.c (decode_mode_spec): Remove handling of %t.
1899 * msdos.c (careadlinkatcwd): Remove.
1901 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1903 * lread.c (skip_dyn_bytes): New function (bug#12598).

1983 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1985 * xdisp.c (window_buffer_changed): region_showing can be negative,
1986 which still means region is being displayed.
1987 (redisplay_internal): Resurrect code that forced redisplay of the
1988 whole window when showing region and the mark has changed.
1989 Record the new mark position to allow redisplay optimizations.
1990 (display_line): If it->region_beg_charpos is non-zero, set the

1993 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1994 not bitfield of 1 bit.
1996 2013-02-03 Daniel Colascione <dancol@dancol.org>
1998 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1999 daemon mode works on cygw32 when Emacs is installed and not just
2002 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
2004 Avoid file time stamp bug on MS-Windows (Bug#13149).
2005 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
2006 as FAT32 doesn't update time stamps when truncating them.
2007 Also, check that a file time stamp is not a multiple of 100 ns;
2008 this should catch all instances of the problem on MS-Windows,
2009 as its native file system resolution is 100 ns or worse, and
2010 checking for a non-multiple of 100 ns should impose only a small
2011 overhead on systems with ns resolution.
2013 2013-02-02 Eli Zaretskii <eliz@gnu.org>
2015 Avoid encoding file names on MS-Windows when they need to be run
2016 through dostounix_filename.
2017 * w32.c (normalize_filename): Accept an additional argument
2018 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
2019 downcase it even if w32-downcase-file-names is non-nil.
2020 (dostounix_filename): Accept an additional argument MULTIBYTE and
2021 pass it to normalize_filename.
2022 (emacs_root_dir): Adjust.
2024 * msdos.h (dostounix_filename): Adjust prototype.
2026 * w32.h (dostounix_filename): Adjust prototype.
2028 * msdos.c (dostounix_filename): Accept an additional argument and
2030 (init_environment): Adjust callers of dostounix_filename.
2032 * fileio.c (Ffile_name_directory, file_name_as_directory)
2033 (directory_file_name, Fexpand_file_name)
2034 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
2036 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
2038 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
2039 variables, as egetenv is case-insensitive for DOS_NT.
2041 * dired.c (file_name_completion): Don't call Fdirectory_file_name
2042 with an encoded file name.
2044 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2045 Adjust calls to dostounix_filename.
2047 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2049 * unexw32.c (unexec): Adjust call to dostounix_filename.
2051 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2053 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2056 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2059 * callproc.c (Fcall_process): Make sure program name in PATH and
2060 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2061 is passed to exec/spawnve, which fails unless the file-name
2064 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2065 even if w32-quote-process-args is nil.
2067 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2069 Fix timestamp bug when write-region appends nothing (Bug#13149).
2070 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2071 the file's time stamp doesn't change if Emacs happens to write nothing
2072 to the file, and on a buggy file system this could cause Emacs to
2073 incorrectly infer that the file system doesn't have the bug.
2074 Avoid this problem by inhibiting the inference in this case.
2076 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2078 * window.h (struct window): Convert base_line_number, base_line_pos
2079 and column_number_displayed members from Lisp_Object to ptrdiff_t.

2087 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2088 (wset_column_number_displayed, wset_region_showing): Remove.
2089 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2090 (try_scrolling, try_cursor_movement, redisplay_window)
2091 (try_window_reusing_current_matrix, try_window_id, display_line)
2092 (display_mode_lines, decode_mode_spec): Adjust users.
2093 * .gdbinit (pwinx): Do not print sequence_number.
2095 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2097 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2098 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2099 * dired.c: Include <fcntl.h>.
2100 (open_directory): New function, which uses open and fdopendir
2101 rather than opendir. DOS_NT platforms still use opendir, though.

2104 (directory_files_internal, Ffile_attributes): Use it.
2105 (file_attributes, file_name_completion_stat): First arg is now fd,
2106 not dir name. All uses changed. Use fstatat rather than lstat +

2109 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2110 (emacs_readlinkat): New function, with much of the old
2111 Ffile_symlink_p, but with an fd argument for speed.
2112 It uses readlinkat rather than careadlinkatcwd, so that it
2113 need not assume the working directory.
2114 (Ffile_symlink_p): Use it.
2115 * filelock.c (current_lock_owner): Use emacs_readlinkat
2116 rather than emacs_readlink.
2117 * lisp.h (emacs_readlinkat): New decl.
2118 (READLINK_BUFSIZE, emacs_readlink): Remove.
2119 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2120 (emacs_norealloc_allocator, emacs_readlink): Remove.
2121 This stuff is moved to fileio.c.
2122 * w32.c (fstatat, readlinkat): New functions.
2123 (careadlinkat): Don't check that fd == AT_FDCWD.
2124 (careadlinkatcwd): Remove; no longer needed.

2133 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2135 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2136 (sys_close): Zero out the flags for the file descriptor before
2137 closing it. (Bug#13546)
2139 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2140 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2141 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2144 * w32.c (w32_get_long_filename, init_environment, readlink):
2145 Support file names encoded in DBCS codepages.
2146 (readlink): Use the current file-name-coding-system, not the ANSI
2147 codepage, to decode and handle targets of symlinks.
2149 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2151 * w32.c (opendir): Now accepts a 'const char *'.

2158 (Vredisplay_preemption_period): Likewise.
2159 (update_frame, update_single_window, update_window, update_frame_1):
2160 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2161 used, following the 2012-06-22 change.

2165 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2167 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>

2170 debugging code. Adjust comment style here and there.
2171 * insdel.c (insert_1): Remove.
2172 * lisp.h (insert_1): Remove prototype.
2173 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2175 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2177 * w32.c (max_filename_mbslen): New function.
2178 (normalize_filename, readdir): Use it to detect locales where ANSI
2179 encoding of file names uses a double-byte character set (DBCS).
2180 If a DBCS encoding is used, advance by characters using
2181 CharNextExA, instead of incrementing a 'char *' pointer.
2182 Use _mbslwr instead of _strlwr. (Bug#13515)
2184 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2185 request of memory reservation to 1.7GB. (Bug#13065)

2197 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2199 Drop async_visible and async_iconified fields of struct frame.
2200 This is possible because async input is gone; for details, see
2201 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2202 * frame.h (struct frame): Remove async_visible and async_iconified
2203 members, convert garbaged to unsigned bitfield. Adjust comments.

2205 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2206 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2207 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2208 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2210 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2211 properly. Likewise for obscured.

2225 * xdisp.c (message2, message2_nolog): Remove functions.
2226 (message3, message3_nolog): Extract nbytes and multibyteness directly
2227 from the string. Change all callers.
2228 (message3_nolog): Don't set message_enable_multibyte since set_message
2229 will reset it anyway.
2230 (message1, message1_nolog): Use message3.
2231 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2232 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2233 (set_message): Drop all but the second arg, which has to be a string.
2234 (set_message_1): Simplify now that we know that a1 is NULL and the
2235 second arg is a string.

2247 * editfns.c (message_text, message_length): Remove vars.
2248 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2249 * fileio.c (auto_save_error): Use message3 instead of message2.

2297 set_file_security returns FALSE. Avoids spurious errors when
2300 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2302 * fileio.c (Finsert_file_contents): Revert code introduced at
2303 2013-01-18 in favor of the simpler and generally better fix.
2304 Save stack space by removing 'buffer' and reusing 'read_buf'
2307 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2309 * lisp.h (eabs): Define unconditionally (Bug#13419).
2310 The old "#if !defined (eabs)" was an unnecessary revenant of back
2311 when this macro was called "abs". Document 'eabs' better.
2313 2013-01-19 Glenn Morris <rgm@gnu.org>
2315 * fns.c (Frandom): Doc fix.
2317 2013-01-19 Eli Zaretskii <eliz@gnu.org>

2322 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2323 when there are lots of overlays.
2324 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2325 for the details and a way to reproduce.
2327 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2329 * fileio.c: Use O_APPEND to append.
2330 This corresponds better to the natural interpretation of "append",
2331 and avoids the need to open the output file twice, or to invoke
2332 lseek when APPEND is neither nil nor a number.
2333 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2334 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2335 file possibly twice, and lseeking to its end; this avoids the
2336 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2337 at the same time: the combination is never needed and apparently
2338 it doesn't work with DOS_NT.
2340 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2341 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2343 Allow floating-point file offsets.
2344 Problem reported by Vitalie Spinu in
2345 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2346 * fileio.c (emacs_lseek): Remove.
2347 (file_offset): New function.
2348 (Finsert_file_contents, Fwrite_region): Use it.
2350 2013-01-19 Chong Yidong <cyd@gnu.org>
2352 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2353 aborting on Fsignal (Bug#13289).
2355 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2357 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2358 set_file_security as failure due to insufficient privileges.
2359 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2360 (fstat): Return owner and group like 'stat' and 'lstat' do.
2362 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2364 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2365 The bug was observed on Ubuntu operating inside a virtual machine,
2366 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2367 The workaround introduces a race condition on non-buggy hosts,
2368 but it's an unlikely race and anyway there's a nearly identical
2369 nearby race that can't be fixed.
2370 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2372 (Fwrite_region): Test for file system time stamp bug.
2373 (init_fileio): New function.
2374 * lisp.h (init_fileio): Declare it.
2375 * emacs.c (main): Call it.

2383 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2384 for the error description produced by valgrind.
2385 * fileio.c (read_non_regular): Rename to read_contents.
2386 Free Lisp_Save_Value object used to pass parameters.
2387 (read_non_regular_quit): Rename to read_contents_quit.
2388 (Finsert_file_contents): Redesign internal file reading loop to adjust
2389 gap and end positions after each read and so help make_gap to work
2390 properly. Do not signal an I/O error too early and so do not leave
2391 not yet decoded characters in a buffer, which was the reason of
2392 redisplay crash. Use list2 to build return value. Adjust comments.
2394 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2396 Close a race when statting and reading files (Bug#13149).
2397 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2398 This avoids a race if the file is renamed between stat and open.
2399 This race is not the problem originally noted in Bug#13149;
2400 see <http://bugs.gnu.org/13149#73> and later messages in the thread.

2445 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2446 extraction from any Lisp_Save_Value slot. Add type checking.

2472 * lread.c (load_unwind):
2473 * nsmenu.m (pop_down_menu):

2499 * editfns.c (save_excursion_save): Pack everything within
2500 Lisp_Save_Value and so avoid xmalloc.
2501 (save_excursion_restore): Adjust to match new layout. Use free_misc
2502 because we do not allocate extra memory any more. Add eassert.
2503 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2504 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

2593 which has already arranged for that.
2594 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.

2777 2012-12-27 Glenn Morris <rgm@gnu.org>
2779 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2780 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2782 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2784 * fileio.c (file_name_as_directory, directory_file_name):
2785 Accept an additional argument MULTIBYTE to indicate whether the input C
2786 came from a multibyte or a unibyte Lisp string; all callers
2787 adjusted. Don't assume the input string is always multibyte.
2789 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2790 don't ENCODE_FILE them, and return a unibyte string if the input
2792 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2793 don't assume the input strings will always be multibyte. If the
2794 input strings are multibyte, decode strings obtained from C
2797 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2799 * lisp.h (toplevel): Add two notices to the comment about
2800 defining a new Lisp data type.
2801 * print.c (print_object): If Lisp_Save_Value object's pointer
2802 is the address of a memory area containing Lisp_Objects, try
2804 * alloc.c (valid_lisp_object_p): Adjust comment.
2806 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2808 * keyboard.c (record_asynch_buffer_change): Initialize an event
2809 only if it's really needed.
2810 * frame.h (enum output_method): Remove output_mac member since
2811 it's a leftover from the deleted code.
2812 * frame.c (Fframep): Adjust user here ...
2813 * terminal.c (Fterminal_live_p): ... and here.
2814 * coding.c (Qmac): Now here because it's only used to denote
2815 end-of-line encoding type.
2816 (syms_of_coding): DEFSYM it.
2817 * frame.h (Qmac): Remove duplicated declaration.
2819 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2821 * window.c (select_window_1): Now static, since it's used only here.
2823 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2825 * window.c (window_body_cols): Subtract display margins from the
2826 window body width on TTYs as well. See
2827 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2828 for the original report.
2830 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2832 * xdisp.c (redisplay_window): Remove inner local variable
2833 because the outer shadowed one has the same meaning.
2834 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2836 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2837 (xg_create_tool_bar): Adjust users.
2839 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2841 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2842 * buffer.c (Fget_buffer_create): Use it to set compact field of
2843 struct buffer_text to avoid accessing an uninitialized value
2844 when compact_buffer is called for the first time.
2845 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2846 (Fset_buffer_modified_p): Use buffer_window_count to check
2847 whether the buffer is displayed in some window.
2848 * xdisp.c (message_dolog): Likewise.
2850 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2852 * w32.c (acl_set_file): If setting the file security descriptor
2853 fails, and the new DACL is identical to the existing one, silently
2854 return success. This fixes problems for users backing up their
2855 own files without having the necessary privileges for setting
2856 security descriptors.
2858 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2860 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2861 after WaitForSingleObject returns normally. This expedites reader
2862 thread shutdown when delete_child triggers it.
2863 (reap_subprocess): More accurate commentary for why we call
2864 delete_child only when cp->fd is negative.
2866 * w32.c (sys_close): Do not call delete_child on a subprocess
2867 whose handle is not yet closed. Instead, set its file descriptor
2868 to a negative value, so that reap_subprocess will call
2869 delete_child on that subprocess when its SIGCHLD arrives.
2870 This avoids closing handles used for communications between sys_select
2871 and reader_thread, which doesn't give sys_select a chance to
2872 notice that the process exited and invoke the SIGCHLD handler for
2875 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2877 * nsfns.m (Fns_do_applescript): Run event loop until script has
2878 been executed (Bug#12969).
2879 (ns_run_ascript): Chech as_script for nil, set to nil after
2882 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2884 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2886 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2888 * w32term.c (w32fullscreen_hook): New function.
2889 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2891 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2893 * fileio.c (Finsert_file_contents): Doc fix.
2895 * w32proc.c (new_child, delete_child, find_child_pid): For a
2896 subprocess, consider its slot being in use as long as its process
2897 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2898 slot when a new process is started immediately after killing
2899 another one, without waiting enough time for the first process to
2900 be reaped and resources allocated for it be orderly freed.
2902 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2904 2012-12-21 Chong Yidong <cyd@gnu.org>
2906 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2908 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2910 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2912 * w32.c (get_name_and_id): Always pass NULL as the first argument
2913 of lookup_account_sid. Avoids crashes with UNC file names that
2914 refer to DFS domains, not to specific machine names. (Bug#12621)
2915 Remove now unused argument FNAME; all callers changed.
2916 (get_file_owner_and_group): Remove now unused argument FNAME; all
2919 2012-12-21 Chong Yidong <cyd@gnu.org>
2921 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2922 error for invalid chars, don't check for a nil return value.
2924 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2926 Avoid calls to CHAR_TO_BYTE if byte position is known.
2927 * editfns.c (make_buffer_string_both): Use move_gap_both.
2928 (Fbuffer_string): Use make_buffer_string_both.
2929 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2931 (buf_bytepos_to_charpos): Likewise.
2932 (charpos_to_bytepos): Remove.
2933 * fileio.c (Finsert_file_contents): Use move_gap_both.
2934 * search.c (Freplace_match): Likewise.
2935 * process.c (process_send_region): Likewise. Use convenient
2936 names for byte positions.
2937 * lisp.h (charpos_to_bytepos): Remove prototype.
2938 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2939 * insdel.c (move_gap): Likewise.
2941 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2943 * xdisp.c (redisplay_internal): Remove now-unused local.
2945 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2947 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2948 (redisplay_internal): Don't bother selecting the frame to get the
2949 proper value of frame-local variables (bug#13225).
2951 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2953 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2954 Rename 4th argument since it may be buffer or string. Adjust comment.
2955 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2957 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2959 * coding.c (Fdetect_coding_region): Do not check start and end with
2960 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2961 (code_convert_region): Likewise.
2963 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2965 * w32.c (acl_get_file, acl_set_file): Run the file name through
2966 map_w32_filename, and resolve any symlinks in the file name, like
2968 (acl_set_file): Call revert_to_self, if any privileges were
2971 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2973 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2974 ($(BLD)/w32.$(O)): Update dependencies.
2976 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2978 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2979 propagate redisplay's scrolling (if any) to the right window.
2980 (redisplay_internal): Use ensure_selected_frame.
2981 (display_mode_lines): Complete last fix.
2982 * window.c (select_window_1): New func, extracted from select_window.
2983 (select_window): Use it.
2984 * window.h (select_window_1): Declare.
2986 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2988 Emulate Posix ACL APIs on MS-Windows.
2989 * w32.c: Include sddl.h and sys/acl.h.
2990 (SDDL_REVISION_1): Define if not already defined.
2991 (g_b_init_get_security_descriptor_dacl)
2992 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2993 (g_b_init_is_valid_security_descriptor)
2994 (g_b_init_set_file_security): New static flags.

3005 (convert_sddl_to_sd, acl_valid, acl_to_text, acl_from_text)
3006 (acl_free, acl_get_file, acl_set_file): New functions.
3008 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
3010 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
3012 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
3013 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
3014 for some of that bug's symptoms can now cause Emacs to abort.
3015 Remove the workaround.
3016 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
3017 The bug that caused SIGCHLD to get lost has been fixed, and the
3018 workaround for it can now cause Emacs to abort.
3020 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
3022 * sysdep.c (emacs_abort): Bump backtrace size to 40.
3023 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
3024 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
3026 2012-12-16 Romain Francoise <romain@orebokech.com>
3028 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
3029 (Fcopy_file): Change last arg to `preserve_extended_attributes'
3030 and copy ACL entries of file in addition to SELinux context if set.
3031 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
3033 * Makefile.in (LIBACL_LIBS): New macro.
3036 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
3038 * fileio.c (internal_delete_file): Use bool for boolean.
3040 2012-12-15 Eli Zaretskii <eliz@gnu.org>
3042 Fix bug #13079 on MS-Windows with temp files not being deleted.
3043 * w32.h (_child_process): New members input_file and
3045 (register_child): First argument is now pid_t.
3046 (record_infile, record_pending_deletion): New prototypes.
3048 * w32proc.c (new_child): Initialize input_file and
3049 pending_deletion members of the child.
3050 (delete_child): Delete the child's temporary input file, if any,
3051 that is pending deletion.
3052 (register_child): First argument is now pid_t.
3053 (record_infile, record_pending_deletion): New functions.
3054 (reap_subprocess): Fix a typo in DebPrint string.
3055 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3057 * fileio.c (internal_delete_file): Return an int again: non-zero
3058 if delete-file succeeds, zero otherwise.
3060 * lisp.h (internal_delete_file): Adjust prototype.
3062 * callproc.c (Fcall_process): Don't overwrite infile with result
3064 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3065 asynchronous subprocess, record the name of the input file name,
3067 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3068 delete the file, record it as pending deletion when the subprocess
3071 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3073 * editfns.c [HAVE_PWD_H]: Include grp.h.
3075 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3077 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3079 Fix permissions bugs with setgid directories etc. (Bug#13125)
3080 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3081 to mark it as a placeholder. The old value was often wrong.
3082 The only user of this attribute has been changed to use
3083 file-ownership-preserved-p instead, with its new group arg.
3084 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3086 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
3088 * xdisp.c (select_frame_for_redisplay, display_mode_lines):

3091 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3093 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3094 try to get accurate owner and group information from NT file
3095 security APIs. This is to make most callers of 'stat' and
3096 'lstat', which don't need that information, much faster.
3098 * dired.c (Ffile_attributes) [WINDOWSNT]:
3099 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3100 owner and group information from 'lstat'.
3102 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3104 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3105 as that confuses set-auto-coding, so insist on the head-read
3106 returning the full 1024 bytes. Let lseek compute the tail offset;
3107 less work for us. Do not ignore I/O errors when reading the tail.
3109 * xdisp.c: Minor style fixes.
3110 (init_iterator): Hoist assignment out of if-expression.
3111 (markpos_of_region): Callers now test for sign, not for -1.
3113 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
3115 Minor redisplay optimization when the region length is zero.
3116 * xdisp.c (markpos_of_region): New function.
3117 (init_iterator): Do not highlight the region of zero length.
3118 (redisplay_window): Check whether the region is of non-zero length.
3119 (try_cursor_movement): Allow if the region length is zero.
3120 (try_window_reusing_current_matrix, try_window_id): Likewise.
3122 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3124 * search.c (search_buffer): Check the inverse translations of each
3125 character in pattern when the buffer being searched is unibyte.
3128 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3130 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3131 files, fixing a regression from 24.2.
3132 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3134 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3136 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3137 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3138 Remove unnecessary S_ISLNK test, as (contra the comments) this
3139 function can't copy symlinks. Improve quality of error message
3140 when attempting to copy files that are neither regular files nor
3143 2012-12-12 Dmitry Antipov <dmantipov@yandex.ru>
3145 * dispnew.c (set_window_cursor_after_update): Use clip_to_bounds.

3147 * window.c (Frecenter):
3148 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
3149 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
3151 2012-12-12 Daniel Colascione <dancol@dancol.org>
3153 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
3154 the dumped Emacs is not a sparse file, greatly improving Cygwin
3155 "make bootstrap" performance.
3157 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
3159 * inotify.c (inotify_callback): Generate an Emacs event for every
3160 incoming inotify event.
3162 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3164 * xdisp.c (handle_face_prop): Fix logic of computing
3165 it->start_of_box_run_p.
3166 (append_space_for_newline): If the glyph row is R2L, reset the
3167 iterator's end_of_box_run_p flag before prepending the space glyph.
3168 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3169 iterator's start_of_box_run_p flag before prepending the stretch.
3170 (append_glyph, produce_image_glyph, append_composite_glyph)
3171 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3172 left_box_line_p and right_box_line_p flags of the glyph for R2L
3173 glyph rows. (Bug#13011)
3175 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3177 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
3178 if changed buffer is not shown in a window.
3179 * insdel.c (prepare_to_modify_buffer): Likewise.
3180 * window.c (replace_buffer_in_windows_safely): Do nothing
3181 if buffer is not shown in a window.
3182 (Fforce_window_update): Likewise if string or buffer argument
3185 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3187 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
3188 encoded_file_name, which is what it is.
3190 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3192 Consistently use marker_position and marker_byte_position.
3193 * fringe.c (Ffringe_bitmaps_at_pos):
3194 * indent.c (Fvertical_motion):
3195 * insdel.c (prepare_to_modify_buffer):
3196 * keyboard.c (make_lispy_position):

3199 (Fset_window_configuration):
3200 * xdisp.c (message_dolog, with_echo_area_buffer_unwind_data)
3201 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
3202 Replace direct access to marker fields with calls
3203 to marker_position and/or marker_byte_position.
3205 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
3207 * makefile.w32-in (SIG2STR_H): New macro.
3208 (SYSWAIT_H, $(BLD)/emacs.$(O), $(BLD)/process.$(O))
3209 ($(BLD)/w32notify.$(O)): Update dependencies.
3211 2012-12-10 Daniel Colascione <dancol@dancol.org>
3213 * w32term.c, keyboard.c: Fix build break in cygw32 by omitting
3214 Windows file notification functionality unless WINDOWSNT.
3216 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
3219 * w32fns.c (cache_system_info): Initialize the global hinst
3220 variable here so various initialization calls DTRT.
3222 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
3223 (hinst): Remove unneeded extern declaration.
3224 (_start): Remove initialization of above variables; remove
3225 initialization of hinst, as cache_system_info now does that.
3227 * emacs.c (main): Call cache_system_info early in startup; we
3228 previously weren't calling it in Cygwin builds.
3230 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
3231 Teach the autoconf build system how to compile a Windows resource file
3232 and link it to Emacs.

3245 and buffer_local_symbols.
3246 * window.h (buffer_shared): Remove declaration.
3247 (wset_buffer): Convert from inline ...
3248 * window.c (wset_buffer): ... to an ordinary function.
3249 (adjust_window_count): New function.

3369 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3371 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).

3373 * dbusbind.c (Fdbus_init_bus):
3375 * xterm.c (x_term_init):

3386 no longer needed here.
3387 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3388 Move to inside set_time_zone_rule; they don't need file scope any more.
3389 (set_time_zone_rule): Maintain the TZ=value string separately.
3390 (syms_of_editfns): Don't initialize initial_tz;
3391 init_editfns now does it.
3392 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3393 * lisp.h (xputenv): New decl.
3395 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>

3411 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3412 Remove USG and vlimit methods; no longer used these days.
3413 Add #error catchall just in case.
3415 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3416 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3417 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3418 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.

3439 This will cause a production Emacs to dump core instead of
3442 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3444 * frame.c (make_frame): Do not set window's buffer to t.
3445 * window.c (Fsplit_window_internal): Likewise. Previously it was
3446 used to indicate that the window is being set up. Now we use
3447 set_window_buffer for all new windows, so the condition in ...
3448 (Fset_window_buffer): ... is always true and can be removed.
3450 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3452 Convenient macro to check whether the buffer is hidden.
3453 * buffer.h (BUFFER_HIDDEN_P): New macro.
3454 * frame.c (make_frame): Use it. Adjust comment.
3455 * buffer.c (candidate_buffer): New function.
3456 (Fother_buffer, other_buffer_safely): Use it.
3458 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3460 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG

3466 * frame.h (x_char_width, x_char_height): Remove prototypes.

3480 * callproc.c, process.h (record_kill_process):
3481 New function, containing part of the old call_process_kill.
3482 (call_process_kill): Use it.
3483 This does not change call_process_kill's behavior.
3484 * process.c (Fdelete_process): Use record_kill_process to fix a
3485 race condition that could cause Emacs to lose track of a child.
3487 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3489 Avoid code duplication between prev_frame and next_frame.
3490 * frame.c (candidate_frame): New function. Add comment.
3491 (prev_frame, next_frame): Use it. Adjust comment.
3493 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3495 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3496 fails, signal an error instead of continuing with an empty
3498 Encode expanded temp file pattern before passing it to mkstemp or
3501 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3502 Encode the file name before passing it to dostounix_filename, in
3503 case it will downcase it (under w32-downcase-file-names).
3506 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3508 Minor call-process cleanups.
3509 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3510 at the same time as other platforms, to simplify analysis.
3511 No need for fd0_volatile since we have synch_process_fd.
3512 Avoid needless emacs_close; arg is always negative.
3514 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3516 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3519 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3521 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3522 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3523 and mouse_face_hidden members to a bitfields.
3524 * frame.h (struct frame): Remove set-but-not-used space_width member.
3525 (FRAME_SPACE_WIDTH): Remove.
3526 * nsterm.m, w32term.c, xterm.c: Adjust users.
3527 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3528 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3529 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3530 members to a bitfields.
3532 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3534 Don't let call-process be a zombie factory (Bug#12980).
3535 Fixing this bug required some cleanup of the signal-handling code.
3536 As a side effect, this change also fixes a longstanding rare race
3537 condition whereby Emacs could mistakenly kill unrelated processes,
3538 and it fixes a bug where a second C-g does not kill a recalcitrant
3539 synchronous process in GNU/Linux and similar platforms.
3540 The patch should also fix the last vestiges of Bug#9488,
3541 a bug which has mostly been fixed on the trunk by other changes.
3542 * callproc.c, process.h (synch_process_alive, synch_process_death)
3543 (synch_process_termsig, sync_process_retcode):
3544 Remove. All uses removed, to simplify analysis and so that
3545 less consing is done inside critical sections.
3546 * callproc.c (call_process_exited): Remove. All uses replaced
3547 with !synch_process_pid.
3548 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3549 These take the role of what used to be in unwind-protect arg.
3551 (block_child_signal, unblock_child_signal):
3552 New functions, to avoid races that could kill innocent-victim processes.
3553 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3554 (call_process_kill): Record killed processes as deleted, so that
3555 zombies do not clutter up the system. Do this inside a critical
3556 section, to avoid a race that would allow the clutter.
3557 (call_process_cleanup): Fix code so that the second C-g works again
3558 on common platforms such as GNU/Linux.
3559 (Fcall_process): Create the child process in a critical section,
3560 to fix a race condition. If creating an asynchronous process,
3561 record it as deleted so that zombies do not clutter up the system.
3562 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3563 light of these changes. Omit unnecessary call to emacs_close
3564 before failure, as the unwind-protect code does that.
3565 * callproc.c (call_process_cleanup):
3566 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3567 * process.c (record_deleted_pid): New function, containing
3568 code refactored out of Fdelete_process.
3569 (Fdelete_process): Use it.
3570 (process_status_retrieved): Remove. All callers changed to use
3571 child_status_change.
3572 (record_child_status_change): Remove, folding its contents into ...
3573 (handle_child_signal): ... this signal handler. Now, this
3574 function is purely a handler for SIGCHLD, and is not called after
3575 a synchronous waitpid returns; the synchronous code is moved to
3576 wait_for_termination. There is no need to worry about reaping
3577 more than one child now.
3578 * sysdep.c (get_child_status, child_status_changed): New functions.
3579 (wait_for_termination): Now takes int * status and bool
3580 interruptible arguments, too. Do not record child status change;
3581 that's now the caller's responsibility. All callers changed.
3582 Reimplement in terms of get_child_status.
3583 (wait_for_termination_1, interruptible_wait_for_termination):
3584 Remove. All callers changed to use wait_for_termination.
3585 * syswait.h: Include <stdbool.h>, for bool.
3586 (record_child_status_change, interruptible_wait_for_termination):
3588 (record_deleted_pid, child_status_changed): New decls.
3589 (wait_for_termination): Adjust to API changes noted above.
3591 * bytecode.c, lisp.h (Qbytecode): Remove.
3592 No longer needed after 2012-11-20 interactive-p changes.
3594 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3596 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3597 the scroll margin, move point outside the margin. (Bug#13055)
3599 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3601 * gtkutil.c (my_log_handler): New function.
3602 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3604 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3606 * lisp.h (modify_region): Rename to...
3607 (modify_region_1): ...new prototype.
3608 * textprop.c (modify_region): Now static. Adjust users.
3609 * insdel.c (modify_region): Rename to...
3610 (modify_region_1): ...new function to work with current buffer.
3611 Adjust comment and users. Use true and false for booleans.
3613 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3615 * alloc.c (free_save_value): New function.
3616 (safe_alloca_unwind): Use it.
3617 * lisp.h (free_save_value): New prototype.
3618 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3620 (save_excursion_restore): Adjust to match saved data structure.
3621 Use free_save_value to offload some work from GC. Drop obsolete
3624 2012-12-03 Chong Yidong <cyd@gnu.org>
3626 * fileio.c (Vauto_save_list_file_name): Doc fix.
3628 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3630 * w32fns.c: Remove prototype of atof.
3631 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3633 (file_dialog_callback): Make it UINT_PTR.
3635 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3638 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3639 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3642 2012-12-03 Glenn Morris <rgm@gnu.org>
3644 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3646 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3648 Fix xpalloc confusion after memory is exhausted.
3649 * alloc.c (xpalloc): Comment fix.
3650 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3651 and signals an error, do not clear charset_table_size, as
3652 charset_table is still valid.
3653 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3655 Use execve to avoid need to munge environ (Bug#13054).
3656 * callproc.c (Fcall_process):
3657 * process.c (create_process):
3658 Don't save and restore environ; no longer needed.
3659 * callproc.c (child_setup):
3660 Use execve, not execvp, to preserve environ.
3662 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3664 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3666 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3668 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3669 display for sliced images (Bug#10500).

3673 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3675 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3676 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3678 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3680 * xdisp.c (window_outdated): Remove eassert since it hits
3681 some suspicious corner cases (see Bug#13007 and Bug#13012).
3682 (mode_line_update_needed): New function.
3683 (redisplay_internal, redisplay_window): Use it.

3687 (buffer_shared_and_changed): ...near to its real use.
3689 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3691 * callproc.c (Fcall_process): Don't misreport vfork failure.
3693 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3695 * callproc.c (Fcall_process): Fix vfork portability problems.
3696 Do not assume that fd[0], count, filefd, and save_environ survive
3697 vfork. Fix bug whereby wrong errno value could be reported for
3698 pipe failure. Some minor cleanups, too, as follows. Move buf and
3699 bufsize to the context where they're needed. Change new_argv to
3700 be of type char **, as this is more convenient and avoids casts.
3701 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3702 Now local constants, not macros.
3704 2012-11-18 Kenichi Handa <handa@gnu.org>

3720 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).
3721 * dired.c (directory_files_internal, file_name_completion):
3722 Assume EAGAIN and EINTR are defined.
3724 * fileio.c (Fcopy_file): Assume EISDIR is defined.
3725 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
3726 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
3727 * lread.c (readbyte_from_file): Assume EINTR is defined.
3728 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3729 Assume EIO and EAGAIN are defined.
3730 * unexcoff.c (write_segment): Assume EFAULT is defined.
3732 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3734 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3737 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3738 highlighting on the frame was cleared. Prevents assertion
3739 violations when repeatedly clicking on the "Top" link of the
3740 "bread-crumbs" in Info buffers.
3742 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
3744 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
3746 2012-11-24 Ken Brown <kbrown@cornell.edu>
3748 * keyboard.c (HAVE_MOUSE):
3749 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3750 were always defined.
3752 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3754 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3755 between bpos_covered and bpos_max. This fixes cursor display when
3756 several display strings follow each other.
3758 * .gdbinit (pgx): If the glyph's object is a string, display the
3759 pointer to string data, rather than the value of the string object
3760 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3762 * indent.c (Fvertical_motion): If the starting position is covered
3763 by a display string, return to one position before that, to avoid
3764 overshooting it inside move_it_to. (Bug#12930)
3766 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3768 * frame.h (struct frame): Remove display_preempted member
3769 since all users are dead long ago.
3770 * nsterm.h (struct x_output): Use the only dummy member.
3771 * w32menu.c (pending_menu_activation): Remove since not
3773 (set_frame_menubar): Adjust user.
3774 * w32term.h (struct x_output): Drop outdated #if 0 code.
3775 (struct w32_output): Use bitfields for explicit_parent,
3776 asked_for_visible and menubar_active members.
3777 Drop unused pending_menu_activation member.
3778 * xterm.h (struct x_output): Drop outdated #if 0 code.
3779 Use bitfields for explicit_parent, asked_for_visible,
3780 has_been_visible and net_wm_state_hidden_seen members.
3782 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3784 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3785 of a literal "/". (Bug#12955)
3786 (gl-stamp): Invoke fc.exe directly, not through cmd.
3788 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3790 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3791 * dired.c: Assume HAVE_DIRENT_H.
3792 (NAMLEN): Remove, replacing with ...
3793 (dirent_namelen): New function. All uses changed. Use the GNU macro
3794 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3795 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3796 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3797 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3799 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3800 * ndir.h: Rename to ../nt/inc/dirent.h.
3801 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3802 Do not include <dirent.h>; no longer needed.
3803 * w32.c: Include <dirent.h> rather than "ndir.h".
3805 2012-11-23 Chong Yidong <cyd@gnu.org>
3807 * xftfont.c (xftfont_open): Remove duplicate assignment.
3809 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3811 * alloc.c (Fgarbage_collect): Unblock input after clearing
3812 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3813 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3814 * msdos.c (IT_frame_up_to_date): Use it here...
3815 * w32term.c (w32_frame_up_to_date): ...here...
3816 * xterm.c (XTframe_up_to_date): ...and here...
3817 * nsterm.m (ns_frame_up_to_date): ...but not here.
3818 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3820 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3821 Do not check whether GC is in progress.
3823 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3825 * xdisp.c (window_buffer_changed): New function.
3826 (update_menu_bar, update_tool_bar): Use it to
3827 simplify large 'if' statements.
3828 (redisplay_internal): Generalize commonly used
3829 'tail' and 'frame' local variables.
3831 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3833 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3834 with Windows system header.
3836 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3838 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3839 * alloc.c: Assume unistd.h exists.
3840 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3841 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3842 (getwd) [USG]: Remove; no longer needed.
3843 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3844 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3845 * w32.h (getcwd): Remove decl.
3847 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3849 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3850 Make it set selected_window as well.
3851 (update_tool_bar): Use it.
3853 2012-11-21 Ken Brown <kbrown@cornell.edu>
3855 * emacs.c (main): Set the G_SLICE environment variable for all
3856 Cygwin builds, not just GTK builds. See
3857 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3859 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3861 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3862 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3863 Define for the MSVC compiler.
3865 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3867 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3868 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3869 dostounix_filename. Prevents crashes down the road, because
3870 dostounix_filename assumes it gets a unibyte string.
3871 Reported by Michel de Ruiter <michel@sentient.nl>, see
3872 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3874 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3876 Conflate Qnil and Qunbound for `symbol-function'.
3877 * alloc.c (Fmake_symbol): Initialize `function' to Qnil.
3878 * lread.c (init_obarray): Set `function' fields to Qnil.
3879 * eval.c (Fcommandp): Ignore Qunbound.
3880 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3881 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3882 Test NILP rather than Qunbound.
3883 (Ffmakunbound): Set to Qnil.
3884 (Fsymbol_function): Never signal an error.
3885 (Finteractive_form): Ignore Qunbound.
3887 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3889 * eval.c (interactive_p): Remove no-longer-used decl.
3891 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3893 * xdisp.c (buffer_shared): Adjust comment.
3894 (buffer_shared_and_changed): New function.
3895 (prepare_menu_bars, redisplay_internal): Use it to
3896 decide whether all windows or frames should be updated.
3897 (window_outdated): New function.
3898 (text_outside_line_unchanged_p, redisplay_window): Use it.
3899 (redisplay_internal): Likewise. Fix indentation.
3901 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3903 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3904 (syms_of_eval): Remove corresponding defsubr.
3905 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3907 2012-11-19 Daniel Colascione <dancol@dancol.org>
3909 * w32fns.c (Fx_file_dialog):
3910 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3911 cygwin_convert_file_name*.
3913 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3914 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3916 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3918 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3920 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3922 * w32select.c: Include w32common.h before w32term.h, so that
3923 windows.h gets included before w32term.h uses some of its
3924 features, see below.
3926 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3928 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3930 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3932 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3934 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3935 (ns_select): Return at once if events are held (Bug#12834).
3937 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3939 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3940 Needed following 2012-10-20 change. (Bug#12902)
3942 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3944 * w32proc.c (waitpid): Remove unused label get_result.
3946 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3948 * makefile.w32-in (SYSWAIT_H): New macro.
3949 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3950 ($(BLD)/sysdep.$(O)): Update dependencies.
3952 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3954 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3955 * callproc.c (relocate_fd): Assume F_DUPFD.
3956 * emacs.c, term.c (O_RDWR): Remove.
3957 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3958 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3959 * nsterm.m: Assume <fcntl.h> exists.
3960 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3961 (create_pty, Fmake_network_process, server_accept_connection)
3962 (wait_reading_process_output, init_process_emacs):
3964 (wait_reading_process_output): Put in a special case for WINDOWSNT
3965 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3966 It's not clear this is needed, but it's a more-conservative change.
3967 (create_process): Assume FD_CLOEXEC.
3968 (create_process, create_pty): Assume O_NOCTTY.
3969 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3970 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3971 Omit if not DOS_NT, since F_GETFL is not defined there.
3972 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3973 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3975 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3976 lack it, since gnulib guarantees this.
3977 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3979 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3981 * w32.c (faccessat): Pretend that directories have the execute bit
3982 set. Emacs expects that, e.g., in files.el:cd-absolute.
3984 * w32proc.c (create_child): Don't clip the PID of the child
3985 process to fit into an Emacs integer, as this is no longer a
3987 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3988 reaping only the process specified by PID argument, if that is
3989 positive. Use PID instead of dead_child to know which process to
3990 reap. Wait for the child to die only if WNOHANG is not in
3992 (sys_select): Don't set dead_child.
3994 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3995 as it is no longer needed.
3997 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3999 (record_child_status_change): Remove the setting of
4000 record_at_most_one_child for the !WNOHANG case.
4002 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
4004 Fix problems in ns port found by static checking.
4005 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
4006 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
4007 not to process group.
4008 (ns_select): Use emacs_write, not write, as that's more robust
4009 in the presence of signals.
4010 (fd_handler:): Check for read errors.
4012 2012-11-16 Glenn Morris <rgm@gnu.org>
4014 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
4016 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
4018 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
4020 2012-11-16 Eli Zaretskii <eliz@gnu.org>
4022 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
4023 use the same value of thread handle.
4024 (start_timer_thread): If the timer thread exited (due to error),
4025 clean up by closing the two handles it used. Duplicate the caller
4026 thread's handle here, so it gets duplicated only once, when
4027 launching the timer thread. Set priority of the timer thread, not
4029 (getitimer): Don't duplicate the caller thread's handle here.
4032 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
4034 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
4037 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
4039 Remove no-longer-used pty_max_bytes variable.
4040 * process.c (pty_max_bytes): Remove; unused.
4041 (send_process): Do not set it.
4043 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4045 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4046 Update dependencies.
4048 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4050 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4051 This follows up on the 2012-09-29 patch that removed indirection
4052 for the 'function' field. Reported by Sergey Vinokurov in
4053 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4055 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4057 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4058 different name, as the MS runtime does not have such a function,
4059 and probably never will.) All callers changed. Ignore DIRFD
4060 value if PATH is an absolute file name, to match Posix spec
4061 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4064 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4066 * xdisp.c (echo_area_display, redisplay_internal):
4067 Omit redundant check whether frame_garbaged is set.
4069 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4071 Use faccessat, not access, when checking file permissions (Bug#12632).
4072 This fixes a bug that has been present in Emacs since its creation.
4073 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4074 which must set some sort of record. (Torek's bug report was against
4075 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4076 same common flaw.) See Torek's Usenet posting
4077 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4078 Posted: Fri Apr 8 14:18:56 1983.
4079 * Makefile.in (LIB_EACCESS): New macro.
4081 * callproc.c (init_callproc):
4082 * charset.c (init_charset):
4083 * fileio.c (check_existing, check_executable, check_writable)
4085 * lread.c (openp, load_path_check):
4086 * process.c (allocate_pty):
4088 Use effective UID when checking permissions, not real UID.
4089 * callproc.c (init_callproc):
4090 * charset.c (init_charset):
4091 * lread.c (load_path_check, init_lread):
4092 Test whether directories are accessible, not merely whether they exist.
4093 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4094 * fileio.c (check_existing, check_executable, check_writable)
4096 Use symbolic names instead of integers for the flags, as they're
4098 (check_writable): New arg AMODE. All uses changed.
4099 Set errno on failure.
4100 (Ffile_readable_p): Use faccessat, not stat + open + close.
4101 (Ffile_writable_p): No need to call check_existing + check_writable.
4102 Just call check_writable and then look at errno. This saves a syscall.
4103 dir should never be nil; replace an unnecessary runtime check
4104 with an eassert. When checking the parent directory of a nonexistent
4105 file, check that the directory is searchable as well as writable, as
4106 we can't create files in unsearchable directories.
4107 (file_directory_p): New function, which uses 'stat' on most platforms
4108 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4109 (Ffile_directory_p, Fset_file_times): Use it.
4110 (file_accessible_directory_p): New function, which uses a single
4111 syscall for efficiency.
4112 (Ffile_accessible_directory_p): Use it.
4113 * xrdb.c (file_p): Use file_directory_p.
4114 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4115 * lread.c (openp): When opening a file, use fstat rather than
4116 stat, as that avoids a permissions race. When not opening a file,
4117 use file_directory_p rather than stat.
4118 (dir_warning): First arg is now a usage string, not a format.
4119 Use errno. All uses changed.
4120 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4121 that merely introduced a race.
4122 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4123 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4124 and similarly for the other O_* flags.
4125 * w32.c (sys_faccessat): Rename from sys_access and switch to
4126 faccessat's API. All uses changed.
4127 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4128 (magic_db): Rename from magic_file_p.
4129 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4130 char *, so that we don't have to test for file existence
4131 separately from opening the file for reading. This removes a race
4132 fixes a permission-checking problem, and simplifies the code.
4134 (file_p): Remove; no longer needed.
4136 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4138 Omit glyphs initialization at startup.
4139 * dispnew.c (glyphs_initialized_initially_p): Remove.
4140 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4141 (Fredraw_frame): Move actual code from here...
4142 (redraw_frame): ...to here. Add eassert. Adjust comment.
4143 (Fredraw_display): Use redraw_frame.
4144 * xdisp.c (clear_garbaged_frames): Likewise.
4146 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4148 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4149 passed to pint2str and pint2hrstr to be at most the size of the
4150 frame's decode_mode_spec_buffer. This avoids crashes with very
4151 large values of FIELD_WIDTH argument to decode_mode_spec.
4154 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4156 Fix a race with verify-visited-file-modtime (Bug#12863).
4157 Since at least 1991 Emacs has ignored an mtime difference of no
4158 more than one second, but my guess is that this was to work around
4159 file system bugs that were fixed long ago. Since the race is
4160 causing problems now, let's remove that code.
4161 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4162 whose time stamp is off by no more than a second. Insist that the
4163 file time stamps match exactly.
4165 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4167 * frame.h (struct frame): Convert external_tool_bar member to
4168 1-bit unsigned bitfield.
4169 * termhooks.h (struct terminal): Remove mouse_moved member since
4170 all users are long dead. Adjust comment on mouse_position_hook.

4186 (x_window_to_menu_bar): Likewise.
4187 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4189 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4191 * data.c (Qdefalias_fset_function): Now static.
4193 Another tweak to vectorlike_header change.

4195 Remove, and replace all uses with ...
4196 (next_in_free_list, set_next_in_free_list):
4197 New functions, which respect C's aliasing rules better.
4199 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4201 * window.c (list4i): Rename from 'quad'. All uses changed.
4202 Needed because <sys/types.h> defines 'quad' on Solaris 10.

4216 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4218 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4219 amount when the scroll margins are too large. When scrolling
4220 backwards in the buffer, give up if cannot reach point or the
4221 scroll margin within a reasonable number of screen lines.
4222 Fixes point position in window under scroll-up/down-aggressively when
4223 point is positioned many lines beyond the window top/bottom.
4226 * ralloc.c (relinquish): If real_morecore fails to return memory
4227 to the system, don't crash; instead, leave the last heap

4249 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4251 Fix recently introduced crash on MS-Windows (Bug#12839).
4252 * w32term.h (struct scroll_bar): Use convenient header.
4253 (SCROLL_BAR_VEC_SIZE): Remove.
4254 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4256 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4258 Tweak last vectorlike_header change.
4259 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4260 vectorlike object on the free list. This is introduced to avoid
4261 some (but not all) pointer casting and aliasing problems, see
4262 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4263 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

4267 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4269 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4270 been removed, so remove them here also.
4272 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4274 * doc.c (Fdocumentation): Handle new property
4275 dynamic-docstring-function to replace the old ad-advice-info.
4277 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4279 * fns.c (Qeql, hashtest_eq): Now static.
4281 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4283 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4284 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4285 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

4292 * lisp.h (sxhash_combine): New inline function, with the contents
4293 of the old SXHASH_COMBINE.

4295 special hash function containing a comparison that always yields 1.
4297 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4299 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4300 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4301 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4304 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4306 * image.c (xpm_make_color_table_h): Fix compiler error because
4307 make_hash_table changed.
4309 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4311 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4313 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4315 Use ad-hoc comparison function for the profiler's hash-tables.
4316 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4317 (make_log): Use them.
4318 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4319 call Fequal any more.

4328 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4329 (hash_lookup, hash_remove_from_table): Move assertion checking of
4330 hashfn result here. Check hash-equality before calling cmpfn.

4332 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.
4333 (syms_of_fns): Initialize them.

4342 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4343 value of w32-scroll-lock-modifier is neither nil nor one of the
4344 known key modifiers. (Bug#12806)
4346 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4348 Shrink struct vectorlike_header to the only size field.
4349 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4351 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4352 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4353 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4354 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4355 information from the vector header. Adjust comment.

4370 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4371 (large_vectors): Change type to struct large_vector.
4372 (allocate_vector_from_block): Simplify.
4373 (PSEUDOVECTOR_NBYTES): Replace with...
4374 (vector_nbytes): ...new function. Adjust users.
4375 (sweep_vectors): Adjust processing of large vectors.
4376 (allocate_vectorlike): Likewise.
4377 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4378 Add easserts. Adjust XSETPVECTYPESIZE usage.
4379 (allocate_buffer): Use BUFFER_PVEC_INIT.
4380 (live_vector_p): Adjust to match large vector.
4381 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4382 * buffer.h (struct buffer): Add next member.
4383 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4385 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
4386 * fns.c (internal_equal): Adjust to match enum pvec_type change.

4391 (xvecsize): New command.
4393 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4395 * keyboard.c (event_to_kboard): Do not dereference
4396 frame_or_window field of SELECTION_REQUEST_EVENT
4397 and SELECTION_CLEAR_EVENT events (Bug#12814).
4398 * xterm.h (struct selection_input_event): Adjust comment.
4400 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4402 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4403 such as Scroll Lock, if the respective keys are treated as
4404 function keys, not as modifiers. This avoids destroying non-ASCII
4405 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4407 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4409 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4411 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4413 Restore some duplicate definitions (Bug#12814).
4414 This undoes part of the 2012-11-03 changes. Some people build
4415 with plain -g rather than with -g3, and they need the duplicate
4416 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4417 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4418 Define as macros, as well as as enums or as constants.
4420 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4422 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4423 to keypad keys (Bug#12816).
4425 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4427 Minor adjustments of recently-changed frame functions.
4428 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4429 known to be a frame (we're in the FRAMEP branch).
4430 * lisp.h (Qframep): Remove decl. frame.h declares this.
4431 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4432 since they're meant for Lisp fixnum values.
4434 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4436 * window.c (Fwindow_combination_limit): Revert to the only
4437 required argument and adjust docstring as suggested in
4438 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4439 by Martin Rudalics <rudalics@gmx.at>.
4441 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4443 Widely used frame validity and checking functions.
4444 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4445 * frame.c (decode_live_frame, decode_any_frame): New functions.
4446 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4447 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4448 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
4449 (Fframe_pointer_visible_p): Use decode_any_frame.

4451 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
4452 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
4453 (Fframe_focus): Likewise. Allow zero number of arguments.
4455 (frame_buffer_list, frame_buffer_predicate): Remove.
4456 * lisp.h (frame_buffer_predicate): Remove prototype.
4457 * buffer.c (Fother_buffer): Use decode_any_frame.
4458 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4459 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4460 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4461 (Fclose_font, Ffont_info): Use decode_live_frame.
4462 * fontset.c (check_fontset_name): Likewise.
4463 * terminal.c (Fframe_terminal): Likewise.
4464 * w32fns.c (check_x_frame): Likewise.
4465 * window.c (Fminibuffer_window, Fwindow_at)
4466 (Fcurrent_window_configuration): Likewise.
4467 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4468 Likewise. Allow zero number of arguments. Adjust docstring.
4469 * dispnew.c (Fredraw_frame): Likewise.
4470 * xfaces.c (frame_or_selected_frame): Remove.
4471 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4472 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4473 (Fframe_face_alist): Use decode_live_frame.
4474 * xfns.c (check_x_frame): Likewise.
4476 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4478 * window.c (quad): New function.
4479 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4480 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4481 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4482 (Fwindow_line_height): Use it.
4483 (Fwindow_fringes): Use list3.
4484 (Fwindow_scroll_bars): Use list4.
4485 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4486 (Fwindow_combination_limit): Allow zero number of arguments.
4488 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4490 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4492 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4493 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4494 file descriptor 2 for standard error. (Bug#12805)
4496 2012-11-05 Chong Yidong <cyd@gnu.org>
4498 * process.c (wait_reading_process_output): Revert previous change.
4500 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4502 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4503 This removes code that has been obsolete since around 1990.
4504 * callproc.c (Fcall_process):
4506 * process.c (create_process):
4507 * term.c (dissociate_if_controlling_tty):
4508 Assume setsid exists.
4509 * callproc.c (child_setup): Assume setpgid exists and behaves as
4510 per POSIX.1-1988 or later.
4511 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4512 * emacs.c (shut_down_emacs):
4513 * sysdep.c (sys_suspend, init_foreground_group):
4514 Assume getpgrp behaves as per POSIX.1-1998 or later.
4515 * msdos.c (setpgrp): Remove.
4516 (tcgetpgrp, setpgid, setsid): New functions.
4517 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4518 * term.c (no_controlling_tty): Remove; unused.
4519 * w32proc.c (setpgrp): Remove.
4520 (setsid, tcgetpgrp): New functions.
4522 Simplify by assuming __fpending.
4523 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4524 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4525 Do not assume that __fpending's result fits in int.
4527 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4529 Remove EMACS_OUTQSIZE+sleep hack.
4530 * dispnew.c (update_frame_1): Remove hack for terminals slower
4531 than 2400 bps, which throttled Emacs by having it sleep.
4532 This code hasn't worked since at least 2007, when the multi-tty stuff
4533 was added, and anyway those old terminals are long dead.
4534 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4535 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4537 Fix data-loss with --version (Bug#9574).
4538 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4539 as we can't assume that emacs_strerror is initialized, and strerror
4540 is good enough here.
4541 (main): Invoke atexit earlier, to catch earlier instances of
4542 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4544 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4546 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4547 (keyDown): Remap keypad keys to X11 virtual key codes.
4549 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4551 Fix data-loss with --batch (Bug#9574).
4552 * emacs.c: Include <close-stream.h>.
4553 (close_output_streams): New function.
4554 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4555 and handles errors appropriately.
4556 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4559 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4560 The symptom is a diagnostic "GLib-WARNING **: In call to
4561 g_spawn_sync(), exit status of a child process was requested but
4562 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4563 waitpid(), so exit status can't be returned." The diagnostic
4564 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4565 The real bug is a race condition between Emacs and glib: Emacs
4566 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4567 so that glib can't find it. Work around the bug by invoking
4568 waitpid only on subprocesses that Emacs itself creates.
4569 * process.c (create_process, record_child_status_change):
4570 Don't use special value -1 in pid field, as the caller now must
4571 know the pid rather than having the callee infer it.
4572 The inference was sometimes incorrect anyway, due to another race.
4573 (create_process): Set new 'alive' member if child is created.
4574 (process_status_retrieved): New function.
4575 (record_child_status_change): Use it.
4576 Accept negative 1st argument, which means to wait for the
4577 processes that Emacs already knows about. Move special-case code
4578 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4579 processes that have already been waited for, by testing and
4580 clearing new 'alive' member.
4581 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4582 now does this internally.
4583 (handle_child_signal): Let record_child_status_change do all
4584 the work, since we do not want to reap all exited child processes,
4585 only the child processes that Emacs itself created.
4586 * process.h (Lisp_Process): New boolean member 'alive'.
4588 Omit duplicate definitions no longer needed with gcc -g3.
4589 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4590 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4591 Define only as macros. There's no longer any need to also define
4592 these symbols as enums or as constants, since we now assume
4593 gcc -g3 when debugging.
4595 2012-11-03 Eli Zaretskii <eliz@gnu.org>

4675 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4677 Remove pad from struct input_event.
4678 * termhooks.h (struct input_event): Remove padding field.
4680 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4681 member is never cons for a long time. Adjust comment.
4682 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4683 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4684 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4685 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.

4693 Fix crash when using Emacs as commit editor for git (Bug#12697).
4694 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4695 and it is configured in conf_post.h.
4696 (Fcall_process): Don't invoke both setsid and setpgid; the former
4697 is enough, if it exists.
4698 * callproc.c (Fcall_process, child_setup):
4699 * process.c (create_process): Use setpgid.
4700 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4702 * dispnew.c (init_display): Initialize the foreground group
4703 if we are running a tty display.

4716 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4718 * minibuf.c (read_minibuf): Restore current buffer since
4719 choose_minibuf_frame calling Fset_frame_selected_window may
4720 change it (Bug#12766).

4731 2012-10-29 Daniel Colascione <dancol@dancol.org>
4733 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4734 In preparation for fixing bug#12739, move these functions from
4737 * coding.h, coding.c: ... to here, and compile them only when
4738 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4739 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4741 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4743 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.

4758 remove last_appdefined_event (Bug#12698).
4760 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4762 * frame.c (x_set_font): Catch internal error.
4764 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4766 Avoid overflow in w32 implementation of interval timers.
4767 When possible, for ITIMER_PROF count only times the main thread
4769 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4770 'volatile ULONGLONG' types. All the other data which was
4771 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4772 (GetThreadTimes_Proc): New typedef.
4773 (w32_get_timer_time): New function, returns a suitable time value
4775 (timer_loop): Enter critical section when accessing ULONGLONG
4776 values of the itimer_data struct, as these accesses are no longer
4777 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4778 Remove unused variable.
4779 (init_timers): Initialize s_pfn_Get_Thread_Times.
4780 (start_timer_thread): Don't assign itimer->caller_thread here.

4787 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4788 mouse movement events if the menu bar is active. This avoids
4789 producing a busy "hour-glass" cursor by Windows if the mouse
4790 pointer is positioned over a tooltip shown for some menu item.
4792 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4794 Don't assume process IDs fit in int.
4795 * emacs.c (shut_down_emacs) [!DOS_NT]:
4796 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4797 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4798 Use pid_t, not int, to store process IDs, as 'int'
4799 is not wide enough on a few platforms (e.g., AIX and IRIX).
4801 2012-10-23 Kenichi Handa <handa@gnu.org>
4803 The following change is to make face-font-rescale-alist work

4829 * frame.c (Fmouse_position, Fmouse_pixel_position):
4830 * xdisp.c (produce_stretch_glyph):
4831 Declare local vars only when they're needed.
4832 This is clearer and avoids a warning on OpenBSD about unused vars.

4834 This is safer, and avoids OpenBSD warnings about unused vars.
4835 * keyboard.c (record_menu_key): Remove unnecessary decl.
4836 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4837 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4838 as our definition clashes with OpenBSD's.
4839 * xfaces.c (load_face_colors, check_lface_attrs)
4840 (get_lface_attributes_no_remap, get_lface_attributes)
4841 (lface_fully_specified_p, x_supports_face_attributes_p)
4842 (tty_supports_face_attributes_p, face_fontset, realize_face)
4843 (realize_x_face, realize_tty_face):
4844 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4845 merely Lisp_Object *. This is more informative and avoids
4846 a warning on OpenBSD about accessing beyond an object's size.
4848 2012-10-20 Chong Yidong <cyd@gnu.org>
4850 * lread.c (Fload): Doc fix (Bug#12592).

4876 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4877 (staticpro): If we run out of staticpro slots, die with an
4878 informative error instead of just calling emacs_abort.
4880 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4882 Fix two flaws reported by Dmitry Antipov.

5091 2012-10-11 Paul Eggert <eggert@cs.ucla.edu>
5093 * marker.c (cached_modiff): EMACS_INT, not int.
5095 * w32select.c (waiting_for_input): Declare by including "keyboard.h"
5096 instead of having a wrong decl.
5097 * nsmenu.m (waiting_for_input): Remove wrong decl.
5099 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5101 keyboard.c, keymap.c: Use bool for booleans.
5102 * dispnew.c (sit_for): Distinguish between 3-way display_option
5103 and boolean do_display.

5133 * keyboard.c (timers_run, swallow_events)
5134 (detect_input_pending_run_timers):
5135 * process.c (wait_reading_process_output):
5136 Use unsigned for counter where wraparound-on-overflow is desired,
5137 since unsigned is guaranteed to have that behavior and signed is not.
5138 (read_char): Use ptrdiff_t for string length.
5139 (get_input_pending): Remove first argument, since it was always
5140 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5141 and behave as if it had that value. Return new value of
5142 input_pending. All callers changed.
5143 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5144 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5146 * keymap.c (push_key_description): Omit last arg, which was always 1.
5147 All callers changed.
5149 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.
5151 2012-10-10 Juanma Barranquero <lekktu@gmail.com>

5165 * termopts.h (flow_control, meta_key): Remove unused decls.
5166 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
5167 Don't include termopts.h.
5169 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5171 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5173 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5175 * commands.h (immediate_quit): Remove duplicate decl.
5177 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5179 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles

5182 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5184 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5186 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5187 match what GetLastError returns. Explain why the function is
5190 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5191 'is_tooltip_frame', to avoid confusion with its global namesake.
5193 2012-10-08 Daniel Colascione <dancol@dancol.org>
5195 * xdisp.c (start_hourglass): Call w32_note_current_window when
5196 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5197 build that caused Emacs to display the hourglass cursor forever.
5199 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5200 which is broken under remote desktop, calculate the number of
5201 colors available for a display based on the display's number of
5202 planes and number of bits per pixel per plane. (bug#10397).
5204 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5206 * nsfont.m (Vfonts_in_cache): New variable.
5207 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5208 are used. Add cached fonts to Vfonts_in_cache.
5209 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5211 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5213 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5215 (FONT_H): Define after FRAME_H.
5216 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5217 Update dependencies.
5219 * w32term.c: Remove leftover declaration of keyboard_codepage.
5221 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5223 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5224 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5225 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5226 (GLOBAL_SOURCES): Add cygw32.c.
5227 ($(BLD)/unexw32.$(O)):
5229 ($(BLD)/w32console.$(O)):
5230 ($(BLD)/w32fns.$(O)):
5231 ($(BLD)/w32heap.$(O)):
5232 ($(BLD)/w32menu.$(O)):
5233 ($(BLD)/w32proc.$(O)): Add w32common.h.
5235 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5237 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5239 2012-10-08 Daniel Colascione <dancol@dancol.org>
5241 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5242 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5243 accidental message numbering hole. Change other messages to
5246 * w32select.h (HAVE_W32SELECT): Remove.
5248 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5249 w32common.h instead of w32heap.h.
5251 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5252 (get_allocation_unit, get_processor_type, get_w32_major_version)
5253 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5254 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5255 (OS_NT, os_subtype, cache_system_info): Move declarations to
5258 * w32heap.c: Include w32common.h.
5259 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5260 (w32_minor_version, w32_build_number, w32_subtype):
5261 Remove duplicate definitions.
5263 * w32fns.c: Include w32common.h; include w32heap.h only in
5266 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5267 Use `report_file_error' instead of `error' in order to better
5268 inform users of what went wrong. Increase NTGUI_UNICODE file
5269 dialog box file name length to 32k, the maximum allowed by the NT
5272 * w32common.h: New file.
5273 (ROUND_UP, ROUND_DOWN, get_page_size)
5274 (get_allocation_unit, get_processor_type, get_w32_major_version)
5275 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5276 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5277 (OS_NT, os_subtype, cache_system_info): Move here.
5279 * unexw32.c, unexcw.c: Include w32common.h.
5281 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5282 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5283 to call syms_of_w32select.
5285 * cygw32.h: Remove obsolete EXFUN declarations.
5287 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5289 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5290 of w32inevt.o from SOME_MACHINE_OBJECTS.
5292 2012-10-08 Daniel Colascione <dancol@dancol.org>
5294 * image.c: Permanent fix for JPEG compilation issue --- limit
5295 jpeglib `boolean' redefinition to Cygwin builds.
5297 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5299 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5301 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5304 2012-10-08 Daniel Colascione <dancol@dancol.org>
5306 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5307 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5308 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5309 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5310 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5311 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5312 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5313 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5314 now a supported configuration.
5316 * Makefile.in: consolidate image variables into LIBIMAGE; add
5317 W32_OBJ and W32_LIBS. Compile new files.
5320 (_DebPrint) declare tracing facility for W32 debugging. We need
5321 to unify tracing later.
5323 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5324 unconditional use of W32 Unicode functions. Cygwin runs only on
5325 100% Unicode operating systems.
5327 * cygw32.c: New file. Define Cygwin-specific facilities.
5328 (Fcygwin_convert_path_to_windows)
5329 (Fcygwin_convert_path_from_windows): New user functions for
5330 accessing Cygwin path-munging routines.
5332 * cygw32.h: New file.
5333 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5334 UTF-16LE strings temporarily inside non-Lisp-visible string
5337 (w32_strerror): Just what it says on the tin.
5339 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5340 also run for Cygwin; both systems have the same problem with using
5341 GUI facilities in a forked child. Also call syms_of_cygw32,
5342 syms_of_w32select in correct places.
5344 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5345 needs fork-then-exec for daemon launching.
5347 * font.h: Include frame.h.
5349 * image.c: Use the image library cache machinery only when we're
5350 compiling for native WINDOWSNT; Cygwin can use shared libraries
5351 like any other Unixlike system.
5353 * keyboard.c: Clarify a comment regarding the input loop.
5355 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5356 functions directly instead of trying to detect at runtime that our
5357 host operating system supports them. We make this change for two
5358 reasons: Cygwin lacks support for the multibyte character
5359 conversion functions used by the legacy menu code, and Cygwin
5360 never needs to rely on non-Unicode APIs.
5362 * unexw32.c (hinst): Declare extern.
5364 * w32.c: Change header order;
5365 (w32_strerror): Move to w32fns.c because we need it for
5366 non-WINDOWSNT builds.
5368 * w32.h: Add #error macro to make sure we don't include w32.h for
5369 Cygwin builds. Remove w32select declarations.
5371 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5372 w32fns.c. w32console.c is WINDOWSNT-only.
5374 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5375 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5377 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5378 (w32_major_version, w32_minor_version, w32_build_number)
5379 (os_subtype, sound_type): Define here
5380 (w32_defined_color): Make color parameter const for consistency
5381 with other _defined_color functions.
5382 (w32_createwindow): Unconditionally call w32_init_class instead of
5383 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5384 through the code is complex and unnecessary because class
5385 registration is practically free.
5386 (w32_name_of_message): New EMACSDEBUG-only function.
5387 (Fset_message_beep): Move here
5388 (Fx_open_connection): Require that the display name for Windows be
5389 "w32" for consistency, emacsclient disambiguation, and maybe, one
5390 day, multi-window-system support.
5391 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5392 Cygwin files for W32 GUI facilities, since these clearly don't
5393 expect Cygwin names.
5394 (_DebPrint): Define.
5395 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5396 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5397 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5398 (w32_last_error): Remove.
5400 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5402 * w32heap.c (syspage_mask): Declare here.
5403 (cache_system_info): Remove.
5405 * w32inevt.c (faked_key): Define globally, not statically.
5406 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5407 (w32_console_toggle_lock_key): Move to w32fns.c.
5409 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5411 * w32proc.c (_DebPrint): Move to w32fns.c.
5412 * w32select.c: Include string.h, stdio.h for Cygwin.
5413 * w32select.h: New File.
5415 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5417 (w32_message_fd): New variable. Under Cygwin, holds the file
5418 descriptor the system used to tell us about pending thread
5421 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5422 that prevented compilation under non-WINDOWSNT systems.
5424 (w32_initialize): Open /dev/windows and assign it to
5425 w32_message_fd. Provide w32 feature.
5427 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5428 (WM_EMACS_INPUT_READY): add.
5429 (prepend_msg, w32_message_fd): Declare globally.
5432 (keyboard_handle): Use only when WINDOWSNT.
5433 (notify_msg_ready): New function. Posts a message to the main
5434 thread's message queue under CYGWIN, which wakes up the main
5435 thread from select(2) by making the /dev/windows file descriptor
5436 ready. Under WINDOWSNT, it sets an event the same way the old
5439 (post, prepend_msg): Actually call notify_msg_ready instead of
5440 setting the input event directly.
5442 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5444 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5445 but it still has blocs in it, don't return it to the system,
5446 instead of aborting. (Bug#12402)
5448 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5450 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5452 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5453 MAC_OS_X_VERSION_10_6.
5454 (syms_of_nsterm): Remove comment about Panther and above for
5456 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5457 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5458 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5460 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5461 MAC_OS_X_VERSION_10_4.
5463 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5464 MAC_OS_X_VERSION_10_2.
5466 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5468 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5469 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5471 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5472 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5473 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5474 Remove ns_in_resize check.
5475 (ns_clear_frame_area): Remove resize handle code.
5477 * nsfns.m (ns_in_resize): Remove.
5478 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5479 Remove ns_in_resize check.
5481 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5483 Improve sys_siglist detection.
5484 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5485 defined as a macro, as is done in Solaris.
5486 (sys_siglist_entries): New macro.
5487 (save_strsignal): Use it.
5488 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5489 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5491 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5493 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5494 fullscreen/Fullscreen.
5496 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5497 tobar_height is new.
5499 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5500 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5501 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5502 (windowDidResize:): Check for correct window if old style fullscreen.
5503 Capitalize word in comment. Remove incorrect comment.
5504 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5505 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5506 error in drawing background.
5507 (toggleFullScreen:): Remove comment. Rearrange calls.
5508 Set toolbar values to zero, save old height in tobar_height.
5509 Restore tool bar height when leaving fullscreen.
5510 (canBecomeMainWindow): New function.
5512 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5514 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5516 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5518 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5520 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5521 that time stamps of directories could also be changed.
5522 Don't request the too broad GENERIC_WRITE, only the more restrictive
5523 FILE_WRITE_ATTRIBUTES access rights.
5525 * fileio.c (Fset_file_times): Special-case ignoring errors for
5526 directories only on MSDOS, not on MS-Windows.
5528 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5530 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5532 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5534 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5535 see whether CreateFile failed.
5537 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5539 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5540 to avoid similar races.
5541 * keyboard.c (pending_signals): Now bool, not int.
5543 Port timers to OpenBSD, plus check for timer failures.
5544 OpenBSD problem reported by Han Boetes.
5545 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5547 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5548 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5549 like OpenBSD, which has timer_settime but does not declare it.
5550 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5551 whether to use itimerspec-related primitives. All uses of
5552 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5554 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5556 * profiler.c (handle_profiler_signal): Fix a malloc race
5557 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5559 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5561 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5563 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5565 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5566 consistent with the change in return value of 'safe_strsignal'.
5568 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5570 Prefer plain 'static' to 'static inline' (Bug#12541).
5571 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5572 (bidi_set_sor_type, bidi_push_embedding_level)
5573 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)

5578 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5579 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5580 Now 'static', not 'static inline'.
5582 Count overruns when profiling; change units to ns.
5583 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5584 Give extra weight to samples after overruns, to attempt to count
5585 the time more accurately.
5586 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5587 the underlying primitives nominally do ns.
5588 (Fprofiler_cpu_start): Document the change. Mention that
5589 the sampling intervals are only approximate.
5591 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5593 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

5596 case for the special 0 coding-system.
5598 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5599 (Fmake_overlay): Remove redundant tests.
5600 (fix_start_end_in_overlays): Remove redundant recentering.

5605 Update dependencies.
5607 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5609 Fix a malloc race condition involving strsignal.
5610 A signal can arrive in the middle of a malloc, and Emacs's signal
5611 handler can invoke strsignal, which can invoke malloc, which is
5612 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5613 Fix it by altering the signal handler so that it does not invoke
5615 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5616 * process.c (status_message): Use const pointer, in case strsignal
5617 is #defined to safe_strsignal.
5618 * sysdep.c (sys_siglist, init_signals): Always define and
5619 initialize a substitute sys_siglist if the system does not define
5620 one, even if HAVE_STRSIGNAL.
5621 (safe_strsignal): Rename from strsignal. Always define,
5622 using sys_siglist. Return a const pointer.
5623 * syssignal.h (safe_strsignal): New decl.
5624 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5626 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5628 * w32proc.c (timer_loop): Fix code that waits for timer
5629 expiration, to avoid high CPU usage.
5631 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5633 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5634 (sweep_weak_table): Remove redundant prototypes.
5636 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5638 * emacs.c: Move the inclusion of TERM_HEADER after including
5639 windows.h on WINDOWSNT. This avoids compilation problems with
5642 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5644 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5645 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5646 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5647 as the previous version used 'void *'.
5649 * ralloc.c (ROUNDUP): Fix last change.
5650 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5653 * w32proc.c <disable_itimers>: New static flag.
5654 (init_timers): Initialize it to zero, after creating the critical
5655 sections used by the timer threads.
5656 (term_timers): Set to 1 before deleting the critical sections.
5657 (getitimer, setitimer): If disable_itimers is non-zero, return an
5658 error indication without doing anything. Reported by Fabrice
5659 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5660 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5662 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5665 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5666 term_ntproc after all the other bookkeeping, to get timers working
5667 as long as possible.
5669 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5671 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5672 Suggested by Juri Linkov in
5673 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5675 Prefer plain 'static' to 'static inline' (Bug#12541).
5676 With static functions, modern compilers inline pretty well by
5677 themselves; advice from programmers often hurts as much as it helps.
5678 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5679 this change shrinks the text size of the Emacs executable by 1.1%
5680 without affecting CPU significantly in my benchmark.
5681 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)

5761 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
5763 Revert the FOLLOW-SYMLINKS change for file-attributes.
5764 Doing it right would require several changes to Tramp, and there's
5765 not enough time to get that tested before the freeze today.
5766 * dired.c (directory_files_internal, Ffile_attributes):
5769 * frame.c (x_report_frame_params): Port better to wider ints.
5770 Do not assume that EMACS_UINT is the same width as uprintmax_t,

5803 * w32.c (init_environment, get_emacs_configuration): Support AMD64
5805 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
5806 compatibility with x64.
5808 * vm-limit.c (lim_data): Now size_t.
5809 (check_memory_limits): Adjust prototypes of real_morecore and
5810 __morecore to receive argument of type ptrdiff_t. Use size_t for

5896 2012-09-30 Kenichi Handa <handa@gnu.org>
5898 * coding.c (decode_coding_ccl, encode_coding_ccl): Pay attention
5899 to the buffer relocation which may be caused by ccl_driver.

5953 Suggested by Eli Zaretskii in
5954 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00811.html>.
5956 2012-09-30 Eli Zaretskii <eliz@gnu.org>
5958 * profiler.c (Fprofiler_cpu_stop): Use timer_settime only if
5959 HAVE_TIMER_SETTIME is defined.
5961 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5963 Profiler improvements: more-accurate timers, overflow checks.
5964 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5965 signal.h, setjmp.h. Include systime.h instead.
5966 (saturated_add): New function.

5973 All uses changed to store the new value.
5974 (handle_profiler_signal): Rename from sigprof_handler_1,
5975 for consistency with other handlers. Do not check whether
5976 cpu_log is a hash-table if garbage collecting, since it
5977 doesn't matter in that case.

5979 for consistency with other handlers.
5980 (setup_cpu_timer): New function, with much of what used to be in
5981 Fprofiler_cpu_start. Check for out-of-range argument.
5982 Prefer timer_settime if available, and prefer
5983 thread cputime clocks, then process cputime clocks, then
5984 monotonic clocks, to the old realtime clock. Use make_timeval
5985 to round more-correctly when falling back to setitimer.
5986 (Fprofiler_cpu_start): Use it.
5987 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5988 Don't assume that passing NULL as the 2nd argument of setitimer
5989 is the same as passing a pointer to all-zero storage.
5990 Ignore SIGPROF afterwards.
5991 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5992 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5993 non-fatal signal handlers. Ignore SIGPROF on startup.
5994 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5995 in profiler.c, since sysdep.c now uses it.
5997 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.
5998 Suggested by Eli Zaretskii in
5999 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

6012 (Fbacktrace_frame): Adjust accordingly.
6014 2012-09-28 Glenn Morris <rgm@gnu.org>
6016 * eval.c (Frun_hook_with_args, Frun_hook_with_args_until_success)

6052 * charset.c, charset.h (maybe_unify_char): Now static.
6053 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6054 Since this stuff is now private to charset.c, there's no need for
6055 a public macro and no need to inline by hand.

6086 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
6088 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
6090 Prefer POSIX timers if available.
6091 They avoid a race if the timer is too close to the current time.
6092 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
6093 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.

6119 * w32.h (Vlibrary_cache): Do not declare.
6121 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6123 * w32proc.c (sys_signal): Handle all signals defined by the
6124 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6125 handlers for signals supported by Windows. Don't override
6126 term_ntproc as the handler for SIGABRT.
6127 (sigaction): Rewrite to call sys_signal instead of duplicating its
6129 (sys_kill): Improve commentary.
6131 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6132 consistency with a signature of a signal handler. All callers
6134 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6135 install term_ntproc as a signal handler for SIGABRT, as that
6136 should be done by the dumped Emacs.
6138 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6140 * w32select.c (term_w32select): Protect against repeated
6141 invocation by setting clipboard_owner to NULL after calling

6156 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6158 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6159 when encountering an unknown bytecode.
6161 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6163 image.c, indent.c: Use bool for booleans.
6164 * dispextern.h (struct image_type): Members valid_p, load, init
6165 now return bool, not int. All uses changed.
6166 * image.c: Omit unnecessary static decls.
6167 (x_create_bitmap_mask, x_build_heuristic_mask):
6168 Return void, not int, since callers don't care about the return value.

6199 2012-09-24 Chong Yidong <cyd@gnu.org>
6201 * chartab.c (Fset_char_table_default): Obsolete function removed.
6203 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6205 Move pid_t related decls out of lisp.h.
6206 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6207 (interruptible_wait_for_termination):
6208 Move these decls from lisp.h to syswait.h, since they use pid_t.
6209 Needed on FreeBSD; see Herbert J. Skuhra in
6210 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6211 * callproc.c: Include syswait.h.

6231 Use bool for boolean.
6232 * gtkutil.c (xg_update_frame_menubar):

6257 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6259 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6260 fatal_error_backtrace.
6262 * w32proc.c (sys_kill): Undo last change: don't do anything when
6263 invoked to deliver SIGABRT to our own process. This is now
6264 handled by emacs_raise.
6266 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6268 * w32term.c (w32_read_socket): Remove leftover reference to
6269 interrupt_input_pending.
6271 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6273 Do not use SA_NODEFER.
6274 Problem reported by Dani Moncayo in
6275 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6277 * sysdep.c (emacs_abort): Do not reset signal handler.
6278 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6279 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6280 wanted even on POSIXish hosts, and it doesn't work on Windows.
6282 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6284 * xterm.c (x_term_init): Call fixup_locale before and after calling
6285 gtk_init (Bug#12392).
6287 2012-09-23 Chong Yidong <cyd@gnu.org>
6289 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6290 Vdynamic_library_alist.
6292 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6293 (Fgnutls_available_p): Caller changed.
6295 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6296 (Flibxml_parse_xml_region): Likewise.
6298 * dispextern.h (struct image_type): Remove arg from init function.
6300 * image.c (Finit_image_library, lookup_image_type)
6301 (define_image_type): Remove now-unneeded second arg.
6302 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6303 (init_tiff_functions, init_gif_functions, init_svg_functions):
6304 Arglist and w32_delayed_load calling convention changed.
6305 (gs_type): Remove init_gs_functions; there is no such function.
6306 (valid_image_p, make_image): Fix caller to lookup_image_type.
6308 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6310 Simplify and avoid signal-handling races (Bug#12471).
6312 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6313 Avoid recursive loop if there's a fatal error in the function itself.
6314 * atimer.c (pending_atimers):
6315 * blockinput.h: Don't include "atimer.h"; no longer needed.
6316 (interrupt_input_pending): Remove. All uses removed.
6317 pending_signals now counts both atimers and ordinary interrupts.
6318 This is less racy than having three separate pending-signal flags.
6319 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6321 Rename from their upper-case counterparts BLOCK_INPUT,
6322 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6323 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6324 This makes it easier to access volatile variables more accurately.
6325 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6326 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6327 that's more reliable if the code is buggy and sets
6328 interrupt_input_blocked to a negative value. All uses changed.
6329 * atimer.c (deliver_alarm_signal):
6330 Remove. No need to deliver this to the parent; any thread can
6331 handle this signal now. All uses replaced by underlying handler.
6332 * atimer.c (turn_on_atimers):
6333 * dispnew.c (handle_window_change_signal):
6334 * emacs.c (handle_danger_signal):
6335 * keyboard.c (kbd_buffer_get_event):
6336 Don't reestablish signal handler; not needed with sigaction.
6337 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6339 Rework to avoid unnecessary accesses to volatile variables.
6340 (UNBLOCK_INPUT_TO): Now a function.
6341 (totally_unblock_input, unblock_input): New decls.
6342 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6343 (init_data): Remove. Necessary stuff now done in init_signal.
6344 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6345 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6346 (fatal_error_code): Remove; no longer needed.
6347 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6348 it doesn't always backtrace. All uses changed. No need to reset
6349 signal to default, since sigaction and/or die does that for us now.
6350 Use emacs_raise (FOO), not kill (getpid (), FOO).
6351 (main): Check more-accurately whether we're dumping.
6352 Move fatal-error setup to sysdep.c
6353 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6354 * gtkutil.c (xg_get_file_name, xg_get_font):
6355 Remove no-longer-needed signal-mask manipulation.
6356 * keyboard.c, process.c (POLL_FOR_INPUT):
6357 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6358 * keyboard.c (read_avail_input): Remove.
6359 All uses replaced by gobble_input.
6360 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6361 (kbd_buffer_store_event_hold, gobble_input):
6362 (record_asynch_buffer_change) [USABLE_SIGIO]:
6363 (store_user_signal_events):
6364 No need to mess with signal mask.
6365 (gobble_input): If blocking input and there are terminals, simply
6366 set pending_signals to 1 and return. All hooks changed to not
6367 worry about whether input is blocked.
6368 (process_pending_signals): Clear pending_signals before processing
6369 them, in case a signal comes in while we're processing.
6370 By convention callers now test pending_signals before calling us.
6371 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6372 New functions, to support changes to blockinput.h.
6373 (handle_input_available_signal): Now extern.
6374 (reinvoke_input_signal): Remove. All uses replaced by
6376 (quit_count): Now volatile, since a signal handler uses it.
6377 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6378 All callers changed. Block SIGINT only if not already blocked.
6379 Clear sigmask reliably, even if Fsignal returns, which it can.
6380 Omit unnecessary accesses to volatile var.
6381 (quit_throw_to_read_char): No need to restore sigmask.
6382 * keyboard.c (gobble_input, handle_user_signal):
6383 * process.c (wait_reading_process_output):
6384 Call signal-handling code rather than killing ourselves.
6385 * lisp.h: Include <float.h>, for...
6386 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6387 (pending_signals): Now volatile.
6388 (syms_of_data): Now const if IEEE floating point.
6389 (handle_input_available_signal) [USABLE_SIGIO]:
6390 (terminate_due_to_signal, record_child_status_change): New decls.
6391 * process.c (create_process): Avoid disaster if memory is exhausted
6392 while we're processing a vfork, by tightening the critical section
6394 (send_process_frame, process_sent_to, handle_pipe_signal)
6395 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6397 (send_process): No need for setjmp/longjmp any more, since the
6398 SIGPIPE stuff is now gone. Instead, report an error if errno
6400 (record_child_status_change): Now extern. PID and W are now args.
6401 Return void, not bool. All callers changed.
6402 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6403 Remove. All uses removed. This bug should be fixed now in a
6405 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6406 and record the child status change directly. This avoids the
6407 need to futz with the signal mask.
6408 (process_fatal_action): Move here from emacs.c.
6409 (emacs_sigaction_flags): New function, containing
6410 much of what used to be in emacs_sigaction_init.
6411 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6412 caught by emacs, to make races less likely.
6413 (deliver_process_signal): Rename from handle_on_main_thread.
6415 (BACKTRACE_LIMIT_MAX): Now at top level.
6416 (thread_backtrace_buffer, threadback_backtrace_pointers):
6418 (deliver_thread_signal, deliver_fatal_thread_signal):
6419 New functions, for more-accurate delivery of thread-specific signals.
6420 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6421 (deliver_arith_signal): Handle in this thread, not
6422 in the main thread, since it's triggered by this thread.
6423 (maybe_fatal_sig): New function.
6424 (init_signals): New arg DUMPING so that we can be more accurate
6425 about whether we're dumping. Caller changed.
6426 Treat thread-specific signals differently from process-general signals.
6427 Block all signals while handling fatal error; that's safer.
6428 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6430 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6431 Ignore SIGPIPE unless batch.
6432 (emacs_backtrace): Output backtrace for the appropriate thread,
6433 which is not necessarily the main thread.
6434 * syssignal.h: Include <stdbool.h>.
6435 (emacs_raise): New macro.
6436 * xterm.c (x_connection_signal): Remove; no longer needed
6437 now that we use sigaction.
6438 (x_connection_closed): No need to mess with sigmask now.
6439 (x_initialize): No need to reset SIGPIPE handler here, since
6440 init_signals does this for us now.
6442 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6444 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6445 background rect may be larger (Bug#12245).
6447 2012-09-23 Chong Yidong <cyd@gnu.org>
6449 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6451 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6453 * .gdbinit: Just stop at fatal_error_backtrace.
6454 See Stefan Monnier's request in
6455 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6456 Remove no-longer-used query of system type.
6458 2012-09-22 Chong Yidong <cyd@gnu.org>
6460 * search.c (Freplace_match): Doc fix (Bug#12325).
6462 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6464 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6465 (Fline_end_position): Doc fix.
6467 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6469 2012-09-22 Chong Yidong <cyd@gnu.org>
6471 * dispextern.h (struct image_type): Add new slot, storing a type
6472 initialization function.
6474 * image.c (define_image_type): Call the image initializer function
6475 if it is defined. Arguments and return value changed.
6476 (valid_image_p, make_image): Callers changed.
6477 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6478 (gif_type, imagemagick_type, svg_type, gs_type):
6479 Add initialization functions.
6480 (Finit_image_library): Call lookup_image_type.
6481 (CHECK_LIB_AVAILABLE): Macro deleted.
6482 (lookup_image_type): Call define_image_type here, rather than via
6483 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6484 (syms_of_image): Move define_image_type calls for xbm_type and
6485 pbm_type to lookup_image_type.
6487 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6489 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6490 'idle_timers' from here ...
6491 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6492 lists, to avoid infloops when the timer does something stupid,
6493 like reinvoke itself with the same or smaller time-out.
6496 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6498 * window.c (Fsplit_window_internal): Handle only Qt value of
6499 Vwindow_combination_limit separately.
6500 (Qtemp_buffer_resize): New symbol.
6501 (Vwindow_combination_limit): New default value.
6504 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6506 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6507 the new overlay string. (Bug#10159)
6509 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6511 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6512 or that fprintf is async-signal-safe. POSIX doesn't require
6515 2012-09-22 Chong Yidong <cyd@gnu.org>
6517 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6520 2012-09-22 Kenichi Handa <handa@gnu.org>
6522 * composite.c (composition_reseat_it): Handle the case that a
6523 grapheme cluster is not covered by a single font (Bug#12352).
6525 2012-09-21 Chong Yidong <cyd@gnu.org>
6527 * image.c (define_image_type): Avoid adding duplicate types to
6528 image_types (Bug#12463). Suggested by Jörg Walter.
6530 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6532 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6533 (print_load_command_name): Add case LC_DATA_IN_CODE.
6534 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6536 2012-09-21 Glenn Morris <rgm@gnu.org>
6538 * eval.c (Frun_hook_with_args_until_success)
6539 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6541 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6543 * fileio.c (Ffile_selinux_context): Only call freecon when
6544 lgetfilecon succeeded.
6545 (Fset_file_selinux_context): Likewise. (Bug#12444)
6547 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6549 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6550 reordering, locate the cursor by calling set_cursor_from_row; if
6551 that fails, clear the desired glyph matrix before returning a
6552 failure indication to the caller. Fixes leaving garbled display
6553 when fast scrolling with a down-key. (Bug#12403)
6554 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6555 scrolling through multibyte text.
6557 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6559 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6560 calling mark_vectorlike since that's the one that marks the window.
6561 (mark_discard_killed_buffers): Mark the final cdr.
6562 * window.h (struct window): Move prev/next_buffers to the
6563 non-standard fields.
6564 * window.c (make_window): Initialize prev/next_buffers manually.
6566 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6568 Omit unused arg EXPECTED from socket hooks.
6569 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6570 * nsterm.m (ns_term_init):
6571 * termhooks.h (struct terminal.read_socket_hook):
6572 * w32inevt.c (w32_console_read_socket):
6573 * w32term.c (w32_read_socket):
6574 * xterm.c (XTread_socket):
6575 Omit unused arg EXPECTED. All callers changed.
6576 (store_user_signal_events): Return void, not int, since callers no
6577 longer care about the return value. All uses changed.
6579 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6581 * w32gui.h (XParseGeometry): Do not declare.
6583 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6585 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6586 Ignore 'expected'. See Eli Zaretskii in
6587 <http://bugs.gnu.org/12471#8> (last line).
6589 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6590 (XParseGeometry): Now static. Substitute extremal values for
6591 values that are out of range.
6593 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6595 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6597 * nsfns.m (XParseGeometry): Remove.
6598 (Fx_create_frame): Call x_set_offset to correctly interpret
6599 top_pos in geometry.
6601 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6602 (Fx_parse_geometry): If there is a space in string, call
6603 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6605 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6607 * search.c (scan_buffer): Use character positions in calls to
6608 region_cache_forward and region_cache_backward, not byte
6609 positions. (Bug#12196)
6611 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6612 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6614 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6615 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6616 emacs_blocked_malloc, now deleted.
6618 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6620 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6621 The workaround was for improving performance on Solaris 2.4, but
6622 is getting in the way now. Emacs will still work if someone is
6623 still running Solaris 2.4 in a museum somewhere; Sun dropped
6624 support for Solaris 2.4 in 2003.
6625 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6626 * process.c (create_process) [HAVE_WORKING_VFORK]:
6627 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6628 since Emacs no longer uses vfork on that platform.
6630 2012-09-17 Glenn Morris <rgm@gnu.org>
6632 * emacs.c: Use COPYRIGHT.
6634 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6636 Remove configure's --without-sync-input option (Bug#12450).
6637 When auditing signal-handling in preparation for cleaning it up,
6638 I found that SYNC_INPUT has race conditions and would be a real
6639 pain to fix. Since it's an undocumented and deprecated
6640 configure-time option, now seems like a good time to remove it.
6641 Also see <http://bugs.gnu.org/11080#16>.
6642 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6643 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6644 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6645 (malloc_hysteresis):
6646 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6647 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6648 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6649 (dont_register_blocks, bytes_used_when_reconsidered)
6650 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6651 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6652 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6653 Remove. All uses removed.
6654 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6655 implementation, one that depends on whether the new macro
6656 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6658 * atimer.c (run_timers, handle_alarm_signal):
6659 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6660 (handle_async_input, process_pending_signals)
6661 (handle_input_available_signal, init_keyboard):
6662 * nsterm.m (ns_read_socket):
6663 * process.c (wait_reading_process_output):
6664 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6665 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6667 * xterm.c (XTread_socket):
6669 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6670 * eval.c (handling_signal): Remove. All uses removed.
6671 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6672 All uses replaced with the SYNC_INPUT version.
6673 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6675 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6678 * font.c (Ffont_shape_gstring): Remove unused local.
6680 2012-09-16 Glenn Morris <rgm@gnu.org>
6682 * Makefile.in (clean): No longer run nextstep's clean.
6684 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6686 (ns-app): Move here from ns.mk, and simplify.
6687 (clean): Simplify nextstep entry.
6688 * ns.mk: Remove file.
6690 2012-09-17 Kenichi Handa <handa@gnu.org>
6692 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6693 not covert the last few charactes.
6695 2012-09-16 Kenichi Handa <handa@gnu.org>
6697 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6698 here, but just check the validity of glyphs in the glyph-string.
6700 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6702 * window.c (Fwindow_parameter, Fset_window_parameter):
6703 Accept any window as argument (Bug#12452).
6705 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6707 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6708 to ns_term_init to avoid memory leak.
6710 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6711 explicit retain/release.
6712 (ns_term_init): Only allow one display. Initialize outerpool and
6715 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6717 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6718 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6719 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6720 the Microsoft problem in a different way, by altering ../nt/config.nt.
6722 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6737 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6738 by lisp.h. This completes removal of setjmp.h inclusion
6739 erroneously announced in the previous commit. (Bug#12446)
6741 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6744 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6745 not defined as a macro. The latter happens on MS-Windows.
6748 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6750 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6751 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6752 Some instances of '#include <setjmp.h>' removed, if the
6753 only reason for the instance was because "lisp.h" was included.
6754 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6755 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6756 and _longjmp with the new symbols. Emacs already uses _setjmp if
6757 available, so this change affects only POSIXish hosts that have
6758 sigsetjmp but not _setjmp, such as some versions of Solaris and
6759 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6760 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6761 (png_load_body) [HAVE_PNG]:
6762 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6763 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6764 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6765 since PNG requires jmp_buf. This is the only exception to the
6766 general rule that we now use sys_setjmp and sys_longjmp.
6767 This exception is OK since this code does not change the signal
6768 mask or longjmp out of a signal handler.
6770 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6772 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6773 Include "syssignal.h", for 'main_thread'.
6775 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6777 Avoid out-of-range marker position (Bug#12426).
6778 * insdel.c (replace_range, replace_range_2):
6779 Adjust markers before overlays, as suggested by comments.
6780 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6781 Remove redundant check before calling offset_intervals.
6783 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6785 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6786 current buffer (Bug#12387).
6788 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6790 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6792 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6794 Use a more backwards-compatible timer format (Bug#12430).
6795 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6796 vector element, not from the 4th, since PSECS is now at the end.
6797 (Fcurrent_idle_time): Doc fix.
6799 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6801 Function to mark objects and remove killed buffers at once.
6802 * alloc.c (discard_killed_buffers): Rename to ...
6803 (mark_discard_killed buffers) ... new name. Add marking
6804 of remaining objects. Fix comment. Adjust users.
6805 (mark_object): Do not touch frame buffer lists here.
6806 * frame.c (delete_frame): Reset frame buffer lists here.
6808 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6810 Better workaround for GNOME bug when --enable-gcc-warnings.
6811 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6812 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6813 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6815 Simplify SIGIO usage (Bug#12408).
6816 The code that dealt with SIGIO was crufty and confusing, e.g., it
6817 played tricks like "#undef SIGIO" but these tricks were not used
6818 consistently. Simplify mostly by not #undeffing standard symbols,
6819 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6820 or not as we please) rather than "defined SIGIO" (standard symbol
6821 that we probably shouldn't #undef).
6822 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6823 Modules that need it can include it.
6824 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6825 * dispextern.h (ignore_sigio): New decl.
6826 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6827 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6828 * emacs.c (shut_down_emacs):
6829 * keyboard.c (kbd_buffer_store_event_hold):
6830 Use ignore_sigio rather than invoking 'signal' directly.
6831 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6833 (FIONREAD, SIGIO): Do not #undef.
6834 (tty_read_avail_input): Use #error rather than a syntax error.
6835 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6836 for I_PIPE, used by SETUP_SLAVE_PTY.
6837 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6838 * sysdep.c (croak): Remove; no longer needed. This bit of
6839 temporary code, with Fred N. Fish's comment that it's temporary,
6840 has been in Emacs since at least 1992!
6841 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6842 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6843 * syssignal.h (croak): Remove decl.
6844 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6845 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6846 now that we're termios-only.
6847 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6848 * term.c (dissociate_if_controlling_tty): Use #error rather than
6851 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6852 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6853 to work around GNOME bug 683906.
6854 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6855 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6856 This works around GCC bug 54561.
6858 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6860 More fixes for 'volatile' and setjmp/longjmp.
6861 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6862 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6863 (png_load_body) [HAVE_PNG]:
6864 (jpeg_load_body) [HAVE_JPEG]:
6865 New function, with most of the old parent function's body.
6866 (png_load) [HAVE_PNG]:
6867 (jpeg_load) [HAVE_JPEG]:
6868 Invoke the new function, to avoid longjmp munging our locals.
6869 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6870 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6871 longjmp is passed 2, as the C standard doesn't guarantee this.
6872 Instead, store the failure code into mgr->failure_code.
6874 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6876 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6877 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6878 (syms_of_keyboard): Remove support for unread-command-char.
6880 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6882 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6883 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6884 violation. (Bug#12426)
6886 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6888 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6890 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6892 * eval.c: Add `inhibit-debugger'.
6893 (Qinhibit_debugger): New symbol.
6894 (call_debugger): Bind it instead of Qdebug_on_error.
6895 (maybe_call_debugger): Test Vinhibit_debugger.
6896 (syms_of_eval): Define inhibit-debugger.
6897 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6898 (syms_of_xdisp): Remove inhibit-debug-on-message.
6900 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6902 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6903 If a nonvolatile local variable is written before a _longjmp to
6904 the frame containing the variable, and is read after the _longjmp,
6905 the value read is indeterminate. Some local variables of type
6906 'struct handler' and 'struct catchtag' are used in this way, so
6907 mark each of their slots as volatile if the slot can be set before
6908 _longjmp and read afterwards.
6909 * lisp.h (struct handler): var and chosen_clause are now volatile.
6910 (struct catchtag): val, next, and pdlcount are now volatile.
6912 * bidi.c (bidi_push_it, bidi_pop_it):
6913 * fns.c (copy_hash_table):
6914 * image.c (define_image_type):
6915 * keyboard.c (kbd_buffer_store_event_hold):
6916 * process.c (Fprocess_send_eof):
6917 * xfaces.c (x_create_gc) [HAVE_NS]:
6918 * xgselect.c (xg_select):
6919 Prefer assignment to memcpy when either will do.
6921 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6922 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6923 time an item is removed. No need to mark this function 'inline';
6924 the compiler knows better than we do.
6926 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6928 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6929 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6930 to change_frame_size (Bug#12388).
6931 (windowDidResize:): Pass YES to updateFrameSize.
6933 * nsterm.h: Add delay parameter to updateFrameSize.
6935 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6937 Discard killed buffers from deleted window and frame objects.
6938 This reduces an amount of references to killed buffers and
6939 helps GC to reclaim them faster.
6940 * alloc.c (discard_killed_buffers): New function.
6941 (mark_object): Use it for deleted windows and frames.
6942 (mark_object): If symbol's value is set up for a killed buffer
6943 or deleted frame, restore its global binding.
6944 * data.c (swap_in_global_binding): Add GC notice.
6945 (swap_in_symval_forwarding): Use convenient set_blv_where.
6946 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6947 * window.h: ... to here.
6949 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6951 Convenient macro to check whether the buffer is live.
6952 * buffer.h (BUFFER_LIVE_P): New macro.
6953 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6954 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6956 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6958 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6959 composition cases (Bug#12364).
6961 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6962 overhang of succeeding glyphs overlapping box cursor.
6964 * w32term.c (x_draw_glyph_string): Likewise.
6966 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6968 Simplify, document, and port floating-point (Bug#12381).
6969 The porting part of this patch fixes bugs on non-IEEE platforms
6970 with frexp, ldexp, logb.
6971 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6973 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6974 support, by removing commented-out code and briefly listing the
6975 C89 functions excluded. The commented-out stuff was confusing
6976 maintenance, e.g., we thought we needed cbrt but it was commented out.
6977 (logb): Remove decl; no longer needed.
6978 (isfinite): New macro, if not already supplied.
6979 (isnan): Don't replace any existing macro.
6980 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6981 are present on all C89 platforms.
6982 (Ffrexp): Do not special-case zero, as frexp does the right thing
6984 (Flogb): Do not use logb, as it doesn't have the desired meaning
6985 on hosts that use non-base-2 floating point. Instead, stick with
6986 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6987 frexp, to avoid getting an unspecified result.
6989 * xdisp.c (Qinhibit_debug_on_message): Now static.
6991 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6993 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6994 NSBezierPath (Bug#12131).
6996 2012-09-10 Chong Yidong <cyd@gnu.org>
6998 * fns.c (Fdelq, Fdelete): Doc fix.
7000 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
7002 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
7003 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
7005 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
7007 * lisp.h (make_lisp_ptr): New macro to replace XSET.
7008 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
7011 2012-09-09 Eli Zaretskii <eliz@gnu.org>
7013 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
7014 left fringe if the window has a left margin. This avoids leaving
7015 traces of the cursor because its leftmost pixel is not drawn over.
7017 * dispnew.c (update_window_line): When the left margin area of a
7018 screen line is updated, set the redraw_fringe_bitmaps_p flag of
7019 that screen line. (Bug#12277)
7021 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
7023 Assume C89 or later for math functions (Bug#12381).
7024 This simplifies the code, and makes it a bit smaller and faster,
7025 and (most important) makes it easier to clean up signal handling
7026 since we can stop worring about floating-point exceptions in
7027 library code. That was a problem before C89, but the problem
7028 went away many years ago on all practical Emacs targets.
7029 * data.c, image.c, lread.c, print.c:
7030 Don't include <math.h>; no longer needed.
7031 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
7032 might be autoconfigured, as that never happens.
7034 * doprnt.c (DBL_MAX_10_EXP):
7035 * print.c (DBL_DIG):
7036 Remove. C89 or later always defines these.
7037 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
7038 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
7039 (arith_error, domain_error, domain_error2):
7040 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
7041 no longer needed -- we simply return what C returns. All uses removed.
7042 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7044 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7045 Remove. All uses expanded, as these macros are no longer used
7046 more than once and are now more trouble than they're worth.
7047 (Ftan): Use tan, not sin / cos.
7048 (Flogb): Assume C89 frexp.
7049 (fmod_float): Assume C89 fmod.
7050 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7051 (init_floatfns): Remove. All uses removed.
7053 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7055 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7056 compositeToPoint for OSX < 10.6 (Bug#12390).
7058 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7060 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7061 This produces more-accurate results.
7063 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7065 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7066 changes (Bug#12088).
7068 2012-09-08 Chong Yidong <cyd@gnu.org>
7070 * syntax.c (Fstring_to_syntax): Doc fix.
7072 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7074 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7075 in the internal border.
7076 (x_set_window_size): Remove static variables and their usage.
7077 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7078 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7079 Remove fringe/internal border adjustment (Bug#11052).
7080 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7081 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7082 (ns_fix_rect_ibw): Remove.
7083 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7084 (ns_dumpglyphs_box_or_relief): Ditto.
7085 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7087 (ns_dumpglyphs_image): Ditto.
7088 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7090 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7091 their usage. Add fringe_extended_p and its use as in other terms.
7092 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7093 scroll bar was removed.
7094 (updateFrameSize): New function.
7095 (windowDidResize): Move code to updateFrameSize and call it.
7097 * nsterm.h (EmacsView): Add updateFrameSize.
7099 2012-09-07 Chong Yidong <cyd@gnu.org>
7101 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7103 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7105 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7107 More signal-handler cleanup (Bug#12327).
7108 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7109 Problem introduced when merging patches. Noted by Eli Zaretskii in
7110 <http://bugs.gnu.org/12327#67>.
7111 * floatfns.c: Comment fix.
7112 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7113 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7114 and anyway the declaration is harmless even if SIGDANGER is not defined.
7115 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7116 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7117 source files not surprisingly expected syssignal.h to define, or
7118 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7119 Include <sys/ioctl.h>, for FIONREAD.
7120 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7121 This eliminates a problem whereby other files mysteriously had
7122 to include "syssignal.h" before including "systty.h" if they
7123 wanted to use "#ifdef SIGIO".
7125 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7127 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7129 * w32.c (sigemptyset): Empty the set.
7130 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7132 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7134 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7136 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7137 (mark_object): Likewise for frame objects.
7139 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7141 * syssignal.h (handle_on_main_thread): Always declare,
7142 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7143 This ports to platforms without HAVE_PTHREAD.
7145 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7147 Signal-handler cleanup (Bug#12327).
7148 Emacs's signal handlers were written in the old 4.2BSD style with
7149 sigblock and sigmask and so forth, and this led to some
7150 inefficiencies and confusion. Rewrite these to use
7151 pthread_sigmask etc. without copying signal sets around. Also,
7152 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7153 'signal', and instead use functions that do not attempt to take
7154 over the system name space. This patch causes Emacs's text
7155 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7156 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7157 Do not include <signal.h> or "syssignal.h", as these
7158 modules do not use signals.
7159 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7160 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7161 Do not include <signal.h>, as "syssignal.h" does that for us now.
7162 * atimer.c (sigmask_atimers): New function.
7163 (block_atimers, unblock_atimers): New functions,
7164 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7166 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7167 no longer needed here.
7168 * emacs.c (main): Inspect existing signal handler with sigaction,
7169 so that there's no need to block and unblock SIGHUP.
7170 * sysdep.c (struct save_signal): New member 'action', replacing
7171 old member 'handler'.
7172 (save_signal_handlers, restore_signal_handlers):
7173 Use sigaction instead of 'signal' to save and restore.
7174 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7175 New function. All users of 'signal' modified to use set_sighandler
7176 if they're writeonly, and to use sys_signal if they're read+write.
7177 (emacs_sigaction_init, forwarded_signal): New functions.
7178 (sys_signal): Remove. All uses replaced by calls to sigaction
7179 and emacs_sigaction_init, or by direct calls to 'signal'.
7180 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7181 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7182 all uses replaced by pthread_sigmask etc. calls.
7183 * syssignal.h: Include <signal.h>.
7184 (emacs_sigaction_init, forwarded_signal): New decls.
7185 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7186 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7187 (sigmask, sys_sigmask): Remove; no longer needed.
7188 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7189 (sigblock, sigunblock, sigfree):
7190 (sigsetmask) [!defined sigsetmask]:
7191 Remove. All uses replaced by pthread_sigmask.
7192 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7193 no longer need to be replaced, and its typical old uses
7194 are now done via emacs_sigaction_init and sigaction.
7195 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7196 (sys_sigdel): Remove; unused.
7197 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7199 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7201 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7202 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7204 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7206 Explicitly mark buffer_defaults and buffer_local_symbols.
7207 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7208 mark_local_symbols here.
7209 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7210 since special buffers aren't marked here any more.
7211 (allocate_buffer): Chain new buffer with all_buffers here...
7212 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7214 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7215 (syms_of_buffer): Remove staticpro of the above.
7216 (init_buffer_once): Set names for buffer_defaults and
7217 buffer_local_symbols.
7219 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7221 Use bool for booleans in font-related modules.
7222 * font.c (font_intern_prop, font_style_to_value)
7223 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7224 (generate_otf_features, font_check_otf_features, font_check_otf)
7225 (font_match_p, font_list_entities, font_at):
7226 * fontset.c (fontset_id_valid_p, reorder_font_vector
7227 (fontset_find_font, Fset_fontset_font)
7228 (face_suitable_for_char_p) [0]:
7229 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7230 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7231 (m17n_flt_initialized, ftfont_shape_by_flt):
7232 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7233 * nsfont.m (nsfont_draw):
7234 * w32font.c (w32font_draw):
7235 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7236 Use bool for booleans.
7237 * font.h: Adjust to above API changes.
7238 (struct font, struct font_driver, struct font_driver_list):
7239 Use bool for booleans.
7240 (struct font): Remove useless member encoding_type.
7242 * fontset.c, xftfont.c: Omit unnecessary static decls.
7244 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7246 * alloc.c (mark_object): Revert window marking code
7247 since it's unsafe for the Fset_window_configuration.
7249 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7251 Fix race conditions with signal handlers and errno (Bug#12327).
7252 Be more systematic about preserving errno whenever a signal
7253 handler returns, even if it's not in the main thread. Do this by
7254 renaming signal handlers to distinguish between signal delivery
7255 and signal handling. All uses changed.
7256 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7257 * data.c (deliver_arith_signal): Rename from arith_error.
7258 * dispnew.c (deliver_window_change_signal): Rename from
7259 window_change_signal.
7260 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7261 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7262 * keyboard.c (deliver_input_available_signal): Rename from
7263 input_available_signal.
7264 (deliver_user_signal): Rename from handle_user_signal.
7265 (deliver_interrupt_signal): Rename from interrupt_signal.
7266 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7267 (deliver_child_signal): Rename from sigchld_handler.
7268 * atimer.c (handle_alarm_signal):
7269 * data.c (handle_arith_signal):
7270 * dispnew.c (handle_window_change_signal):
7271 * emacs.c (handle_fatal_signal, handle_danger_signal):
7272 * keyboard.c (handle_input_available_signal):
7273 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7274 * process.c (handle_pipe_signal, handle_child_signal):
7275 New functions, with the actual signal-handling code taken from the
7276 original respective signal handlers, sans the sporadic attempts to
7277 preserve errno, since that's now done by handle_on_main_thread.
7278 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7279 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7280 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7282 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7283 Move initialization of main_thread to sysdep.c's init_signals.
7284 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7285 our usage, and simplifies the mainline code.
7286 (record_child_status_change): New static function, as a helper
7287 for handle_child_signal, and with most of the old child handler's
7289 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7290 (handle_child_signal): Use the above.
7291 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7292 Moved here from emacs.c.
7293 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7294 code moved here from emacs.c's main function.
7295 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7296 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7297 This lets callers save and restore errno properly.
7299 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7301 Remove redundant or unused things here and there.
7302 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7303 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7304 * editfns.c (Fcompare_buffer_substrings): Likewise.
7305 * frame.h (struct terminal, struct font_driver_list):
7306 Remove redundant declarations.
7307 * window.h (Qleft, Qright): Likewise.
7309 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7311 Do not mark objects from deleted buffers, windows and frames.
7312 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7313 (mark_object): Likewise for windows and frames.
7315 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7317 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7318 buffer_defaults and buffer_local_symbols as valid objects.
7319 Return special value to denote them.
7321 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7323 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7324 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7325 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7326 (file_name_absolute_p, Fsubstitute_in_file_name):
7327 (check_executable, check_writable, Ffile_accessible_directory_p)
7328 (Fset_file_selinux_context, Fdefault_file_modes)
7329 (Finsert_file_contents, choose_write_coding_system)
7330 (Fwrite_region, build_annotations, a_write, e_write)
7332 * filelock.c (boot_time_initialized, get_boot_time)
7333 (get_boot_time_1, lock_file_1, within_one_second):
7334 * floatfns.c (in_float):
7335 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7336 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7337 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7338 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7339 * window.c (compare_window_configurations):
7340 Use bool for booleans.
7341 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7342 (Fdefault_file_modes): Now mode_t, not int, for modes.
7343 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7344 (internal_delete_file): Now returns void, not a (boolean) int,
7345 since nobody was looking at the return value.
7346 * lisp.h, window.h: Adjust to above API changes.
7348 * xdisp.c (set_message): Simplify and reindent last change.
7350 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7352 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7354 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7356 * eval.c (call_debugger): Make the function non-static so that we
7357 can call it from set_message.
7359 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7360 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7362 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7364 Give more-useful info on a fatal error (Bug#12328).
7365 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7366 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7367 of doing the work ourselves.
7368 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7369 do most of the work.
7370 (fatal_error_backtrace): New function, taken from the guts
7371 of the old fatal_error_signal, but with a new option to output
7373 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7374 info about the signal than just its number.
7375 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7376 * sysdep.c: Include <execinfo.h>
7377 (emacs_backtrace): New function, taken partly from the previous
7378 code of the 'die' function.
7379 (emacs_abort): Call fatal_error_backtrace rather than abort.
7381 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7383 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7384 eager (load-time) macro-expansion.
7385 * lisp.mk (lisp): Add macroexp.
7387 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7389 Simplify redefinition of 'abort' (Bug#12316).
7390 Do not try to redefine the 'abort' function. Instead, redo
7391 the code so that it calls 'emacs_abort' rather than 'abort'.
7392 This removes the need for the NO_ABORT configure-time macro
7393 and makes it easier to change the abort code to do a backtrace.
7394 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7395 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7396 Remove; sysdep.c's emacs_abort now takes its place.
7397 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7398 'abort' changed to use 'emacs_abort'.
7399 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7400 (abort) [!defined abort]: Rename to ...
7401 (emacs_abort): ... new name.
7402 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7403 the place of the old 'abort' in emacs.c.
7404 * w32.c, w32fns.c (abort): Do not #undef.
7405 * w32.c (emacs_abort): Rename from w32_abort.
7407 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7409 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7410 offsets[j].dv, since the y axis of the screen coordinates points
7411 down, while the y axis of the font definition coordinates points
7412 up. This fixes display of Arabic diacritics such as KASRA and
7413 KASRATAN. (Bug#11860)
7415 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7417 Be more systematic about _setjmp vs setjmp.
7418 * alloc.c (test_setjmp, mark_stack):
7419 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7420 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7421 (png_load, my_error_exit, jpeg_load):
7422 * process.c (send_process_trap, send_process):
7423 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7424 The underscored versions are up to 30x faster on some hosts.
7425 Formerly, the code used setjmp+longjmp sometimes and
7426 _setjmp+_longjmp at other times, with no particular reason to
7427 prefer setjmp+longjmp.
7429 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7431 Fix minor problem found by static checking.
7432 * buffer.c (Fdelete_all_overlays): Return nil.
7434 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7436 * buffer.c (Fdelete_all_overlays): New function.
7438 2012-09-03 Chong Yidong <cyd@gnu.org>
7440 * gtkutil.c: Add extern decl for Qxft.
7442 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

7456 All callers changed.
7457 * eval.c (interactive_p): Omit always-true boolean argument
7458 EXCLUDE_SUBRS_P. All callers changed.
7459 * dispextern.h, lisp.h: Reflect above API changes.
7460 * firstfile.c (dummy): Use the address of 'main', whose signature
7461 won't change, instead of the address of 'initialize', whose
7462 signature just changed from int to bool.
7463 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7464 * msdos.c (fatal_error_in_progress): ... from here.
7465 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7467 (redisplay_internal, unwind_redisplay): Simply clear
7468 REDISPLAYING_P when unwinding, instead of saving its previous,
7469 always-false value and then restoring it.
7471 Clean up some extern decls.
7472 Mostly, this hoists extern decls out of .c files and into .h files.
7473 That way, we're more likely to catch errors if the interfaces change.
7474 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7475 declare xg_mark_data.
7476 * dispextern.h (x_frame_parm_handlers):
7478 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

7494 * xfont.c (x_clear_errors):
7495 * xterm.c (x_frame_parm_handlers):
7496 Remove now-redundant extern decls.
7497 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7498 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7500 * xfaces.c: Remove unnecessary static decls.
7501 * xterm.c (updating_frame): Remove decl of nonexistent object.
7503 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7504 when building globals.h, as the objects that are not built on
7505 this host are not needed to compile C files on this host.
7507 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7509 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

7523 (make_buffer_string, make_buffer_string_both)
7524 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

7536 (set_intervals_multibyte_1, set_intervals_multibyte):
7537 * keyboard.c (decode_timer):
7538 Use bool for boolean.
7539 * intervals.h, lisp.h, systime.h: Reflect above API changes.
7540 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.
7542 2012-09-02 Chong Yidong <cyd@gnu.org>

7547 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7549 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
7550 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

7555 ($(BLD)/w32font.$(O), $(BLD)/w32uniscribe.$(O)): Update dependencies.
7557 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7559 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7560 more than one grapheme cluster passed to the shaper: compute the
7561 offset adjustment values separately for each cluster. (Bug#11860)
7563 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7564 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7565 about implicit conversions from integer to pointer.
7567 2012-09-01 Daniel Colascione <dancol@dancol.org>
7569 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7570 system used too early.
7572 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7574 Better seed support for (random).

7607 Define FRAME_X_SCREEN, FRAME_X_VISUAL.
7609 * menu.c: Include TERM_HEADER instead of listing all possible
7610 window-system headers.
7612 * keyboard.h: Declare ignore_mouse_drag_p whenever we have a
7615 * keyboard.c: Include TERM_HEADER instead of listing all possible
7616 window-system headers.

7622 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
7623 window system declarations.
7625 * frame.h: Move common functions here: set_frame_menubar,
7626 x_set_window_size, x_sync, x_get_focus_frame,
7627 x_set_mouse_position, x_set_mouse_pixel_position,
7628 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7652 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7654 Remove mark_ttys function and fix tty_display_info initialization.
7655 * lisp.h (mark_ttys): Remove prototype.
7656 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
7657 to mark_ttys because all possible values of 'top_frame' slot are
7658 the frames which are reachable from Vframe_list.
7659 * term.c (mark_ttys): Remove.
7660 (init_tty): Safely initialize 'top_frame' slot with Qnil.
7662 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7664 Change struct frame bitfields from unsigned char to unsigned.
7665 * frame.h (struct frame): Change type of 'display_preempted',

7667 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
7668 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
7669 bitfields from unsigned char to unsigned.

7682 2012-08-30 Paul Eggert <eggert@cs.ucla.edu>
7684 * dispnew.c (update_frame_1): Pacify gcc -Wstrict-overflow
7685 for GCC 4.7.1 x86-64.
7687 2012-08-30 Glenn Morris <rgm@gnu.org>
7689 * lread.c (init_lread): For out-of-tree builds, only add the
7690 source directory's site-lisp dir to the load-path if it exists,
7691 consistent with in-tree builds. (Bug#12302)
7693 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
7695 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

7704 (addString:row:): Remove return self, declare return value as void.
7705 (addSplit): Remove return self, declare return value as void.
7706 (clicked:): Remove return self, declare return value as void.
7707 Set dialog_return to button_values[seltag]. Code formatting change.
7708 (initFromContents:isQuestion:): Adjust call to process_dialog.
7709 Code formatting change.
7710 (timeout_handler:): Set timer_fired to YES.
7711 (runDialogAt:): Set timer_fired to NO.
7712 Handle click on close button as quit.
7714 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7715 Add window_closed and button_values. Add void as return value for
7716 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7717 Add process_dialog as new member.
7719 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7721 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it
7722 is not one of the heaps we manage. (Bug#12242)

7762 * xdisp.c (run_window_scroll_functions): Use set_buffer_internal.
7764 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
7766 * dispnew.c: Use bool for boolean.

7781 (do_pending_window_change, change_frame_size)
7782 (change_frame_size_1, sit_for):
7783 Use bool for boolean.
7784 (clear_glyph_matrix_rows): Rename from enable_glyph_matrix_rows,
7785 and remove last int (actually boolean) argument, which was always 0.
7786 All callers changed.
7787 * dispextern.h, frame.h, lisp.h: Reflect above API changes.
7788 * dispextern.h (struct composition_it): Use bool for boolean.
7789 (struct glyph_matrix): Don't assume buffer sizes can fit in 'int'.
7790 (struct bidi_it): Use unsigned:1, not int, for boolean prev_was_pdf.
7791 * dired.c (file_name_completion):
7792 Use bool for boolean. (This was missed in an earlier change.)
7794 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7796 * window.c (Fset_window_configuration): Revert first part of
7799 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
7801 * nsterm.h (NSPanel): New class variable dialog_return.
7803 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
7804 Initialize dialog_return.
7805 (windowShouldClose:): Use stop instead of stopModalWithCode.
7806 (clicked:): Ditto, and also set dialog_return (Bug#12258).
7807 (timeout_handler:): Use stop instead of abortModal. Send a dummy
7809 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
7812 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>

7824 Use bool for booleans.
7825 * dired.c (file_name_completion):

7853 * fileio.c (Finsert_file_contents):
7854 Use bool for booleans.
7855 * coding.h, lisp.h: Reflect above API changes.
7856 * coding.c: Remove unnecessary static function decls.
7857 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7858 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7859 not a boolean 'int', since callers never look at the return value.
7860 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
7861 * coding.h (decoding_buffer_size, encoding_buffer_size)
7862 (emacs_mule_string_char): Remove unused extern decls.
7863 (struct iso_2022_spec, struct coding_system):
7864 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7865 (struct emacs_mule_spec): Remove unused field 'full_support'.
7866 All initializations removed.
7867 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7869 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7871 Fix spare memory change (Bug#12286).
7872 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7873 (valid_lisp_object_p): Likewise.
7875 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7877 * window.c (Fset_window_configuration): Record any window's old
7878 buffer if it's replaced (see Bug#8789). If the new current
7879 buffer doesn't appear in the selected window, go to its old
7882 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7884 Special MEM_TYPE_SPARE to denote reserved memory.
7885 * alloc.c (enum mem_type): New memory type.
7886 (refill_memory_reserve): Use new type for spare memory.
7887 This prevents live_cons_p and live_string_p from incorrect
7888 detection of uninitialized objects from spare memory as live.
7890 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7893 * Makefile.in (.PHONY): versioclean -> versionclean.
7895 Remove unused external symbols.
7896 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7897 * window.c (Qwindow_valid_p, decode_valid_window):
7898 Now static, not extern.
7899 * data.c (Qinterval): Remove; unused.
7900 (syms_of_data): Do not define 'interval'.
7901 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7902 * window.h (decode_valid_window):
7905 * character.c, charset.c, chartab.c: Use bool for booleans.

7915 (char_table_set_range, optimize_sub_char_table)
7916 (map_sub_char_table):
7917 Use bool for boolean.
7918 * character.c (str_to_unibyte): Omit last boolean argument; it was
7919 always 0. All callers changed.
7920 * character.h, charset.h: Adjust to match previous changes.
7921 * character.h (char_printable_p): Remove decl of nonexistent function.
7922 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7923 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7924 are all boolean, so make them single-bit bitfields.
7926 * lisp.h (ASET): Remove attempt to detect side effects.
7927 It was meant to be temporary and it often doesn't work,
7928 because when IDX has side effects the behavior of IDX==IDX
7929 is undefined. See Stefan Monnier in
7930 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7932 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7934 * lisp.h (functionp): New function (extracted from Ffunctionp).
7935 (FUNCTIONP): Use it.
7936 * eval.c (Ffunctionp): Use it.
7938 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7940 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7941 as that's faster and simpler than static storage. Don't bother
7942 with the g_main_context_query overhead if g_main_context_pending
7943 says no events are pending.
7944 (gfds, gfds_size): Remove these static vars.
7945 (xgselect_initialize): Remove; no longer needed.
7946 All uses and decls removed.
7948 * emacs.c (fatal_error_signal_hook): Remove.
7949 All uses removed. This leftover from old code was always 0.
7951 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7952 * casefiddle.c (casify_object, casify_region):
7953 * casetab.c (set_case_table):
7954 * category.c, category.h (word_boundary_p):
7955 * category.h (CHAR_HAS_CATEGORY):
7956 Use bool for booleans, instead of int.
7958 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7960 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7962 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7964 On assertion failure, print backtrace if available.
7965 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7966 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7967 * Makefile.in (LIB_EXECINFO): New macro.
7970 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7971 * bytecode.c (exec_byte_code):
7972 * callint.c (check_mark, Fcall_interactively):
7973 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7974 (getenv_internal, sync_process_alive, call_process_exited):
7975 * lisp.h (USE_SAFE_ALLOCA):
7976 Use bool for booleans, instead of int.
7977 * lisp.h, process.h: Adjust prototypes to match above changes.
7978 * callint.c (Fcall_interactively): Don't assume the mark's
7979 offset fits in 'int'.
7981 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7983 * buffer.c, buffer.h: Use bool for boolean.
7984 * buffer.c (reset_buffer_local_variables)
7985 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7986 (Frestore_buffer_modified_p, Fset_buffer_multibyte):

7988 (overlay_touches_p, overlay_strings, Foverlay_put)
7989 (report_overlay_modification, call_overlay_mod_hooks):
7990 (mmap_enlarge, mmap_set_vars):
7991 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7992 Use bool for booleans, instead of int.
7993 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7994 since the 1-or-0 return value is always ignored anyway.
7995 (mmap_initialized_p):
7996 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7997 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7999 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8001 * bidi.c: Use bool for boolean.
8002 This is a bit more readable, and makes the text segment of bidi.o
8003 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
8004 Presumably it's faster too.
8005 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
8007 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8008 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
8009 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
8010 (bidi_explicit_dir_char, bidi_level_of_next_char)
8011 (bidi_find_other_level_edge, bidi_move_to_visually_next):
8012 Use bool for booleans, instead of int.
8013 * dispextern.h (bidi_init_it, bidi_paragraph_init)
8014 (bidi_unshelve_cache): Adjust decls to match code.
8016 2012-08-23 Martin Rudalics <rudalics@gmx.at>
8018 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
8021 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
8023 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
8024 * atimer.h: Include <stdbool.h>.
8026 2012-08-22 Dan Nicolaescu <dann@gnu.org>
8028 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
8029 compile time tests instead of run time tests on systems that do
8031 (FRAME_MAC_P): Remove leftover from deleted code.
8032 * frame.c (syms_of_frame): Remove leftover from deleted code.
8034 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
8036 * nsterm.m (insertText:): Don't clear modifiers if code is space.
8038 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
8040 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
8041 Otherwise, the compiler complains about (A?B:C) where B is void
8042 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8043 (fontset_add): Return void, for FONTSET_ADD.
8045 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8047 * alloc.c: Use bool for booleans.
8048 (gc_in_progress, abort_on_gc)
8049 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8050 (dont_register_blocks) [GC_MALLOC_CHECK]:
8051 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
8052 (check_string_bytes, make_specified_string, memory_full)
8053 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8054 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8055 (mark_stack, valid_pointer_p, make_pure_string)
8056 (Fgarbage_collect, survives_gc_p, gc_sweep):
8057 Use bool for booleans, instead of int.
8058 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8059 Remove unused local.
8060 * alloc.c (PURE_POINTER_P):
8061 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8062 * editfns.c (Fformat):
8063 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8065 * fns.c (sweep_weak_table):
8066 * lisp.h (suppress_checking, push_message, survives_gc_p)
8067 (make_pure_string, gc_in_progress, abort_on_gc):
8068 * lread.c (readchar, read1):
8069 * print.c (Fprin1_to_string):
8070 * xdisp.c (push_message):
8071 Use bool for booleans affected directly or indirectly by
8074 Make recently-introduced setters macros.
8075 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8076 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8077 (set_fontset_default, set_fontset_fallback): Rename from their
8078 upper-case counterparts, and make them functions rather than macros.
8079 This is more consistent with the other recently-introduced setters.
8080 These don't need to be inline, since they're local.
8082 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8084 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8085 the loop (Bug#12247).
8087 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8089 * lisp.h (vcopy): Use memcpy rather than our own loop.
8090 This fixes a performance regression introduced by the recent
8091 addition of vcopy. This means 'vcopy' will need to be modified
8092 for a copying collector, but that's OK. Also, tighten the
8093 checking in the assertion.
8095 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8097 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8098 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8099 non-base glyph for the width of the base character, according to
8100 what x_draw_composite_glyph_string_foreground expects.
8101 Generate WADJUST value according to composition_gstring_width's
8102 expectations, to produce correct width of the composed character.
8103 Reverse the sign of the DU offset produced by ScriptPlace.
8105 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8107 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8109 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8111 Avoid direct writes to contents member of struct Lisp_Vector.
8112 * lisp.h (vcopy): New function to copy data into vector.
8113 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
8114 * fns.c (Ffillarray): Use ASET.
8115 * keyboard.c (timer_check_2): Use AREF and ASET.
8116 (append_tool_bar_item, Frecent_keys): Use vcopy.
8117 * lread.c (read_vector): Use ASET.
8118 * msdos.c (Frecent_doskeys): Use vcopy.
8119 * xface.c (Finternal_copy_lisp_face): Use vcopy.
8120 (Finternal_merge_in_global_face): Use ASET and vcopy.
8121 * xfont.c (xfont_list_pattern): Likewise.
8123 2012-08-21 Martin Rudalics <rudalics@gmx.at>
8125 * window.c (Fwindow_point): For the selected window always return
8126 the position of its buffer's point.
8127 (Fset_window_point): For the selected window always go in its
8128 buffer to the specified position.
8130 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8132 Setter macros for fontsets.
8133 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8134 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8135 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8138 2012-08-20 Glenn Morris <rgm@gnu.org>
8140 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8141 Don't assume that `ln -f' works.
8143 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8145 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8146 and later about non-assignments with no effect. See discussion at
8147 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8150 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8152 Inline setter functions for Lisp_Objects slots of struct specbinding.
8153 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8156 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8158 * window.c (select_window): Always make selected window's buffer
8161 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8163 Use AREF and ASET for docstrings of category tables.
8164 * category.h (CATEGORY_DOCSTRING): Use AREF.
8165 (SET_CATEGORY_DOCSTRING): Use ASET.
8166 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8168 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8170 Inline setter functions for hash table members.
8171 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8172 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8173 (set_hash_key_and_value, set_hash_index, set_hash_next)
8174 (set_hash_hash): New functions.
8175 * charset.c, fns.c: Adjust users.
8177 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8179 Inline getter and setter functions for per-buffer values.
8180 * buffer.h (per_buffer_default, set_per_buffer_default)
8181 (per_buffer_value, set_per_buffer_value): New functions.
8182 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8183 * buffer.c, data.c: Adjust users.
8185 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8187 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8189 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8191 Rely on <config.h> + <unistd.h> to declare 'environ',
8192 as gnulib does this if the system doesn't.
8193 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8194 Remove declaration. MS-Windows declares it on stdlib.h which is
8195 included by conf_post.h.
8196 * emacs.c (environ) [DOUG_LEA_MALLOC]:

8201 (start_of_data): Remove decl; mem-limits.h provides it.
8203 * xdisp.c (handle_invisible_prop): Make it a bit faster
8204 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8206 2012-08-19 Chong Yidong <cyd@gnu.org>

8617 Use bool, not int, for Lisp booleans.

9069 value of EMACSLOADPATH, as it is no longer needed.
9070 (check_windows_init_file): Now external, not static.
9071 Use Vload_path as is, without adding anything, as this function is now
9072 called when Vload_path is already set up.
9074 * w32.h (check_windows_init_file): Add prototype.
9076 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
9077 directory, ignore the /*/i386/ tail in Vinvocation_directory, for
9078 compatibility with Posix platforms.
9079 (main): Move the call to check_windows_init_file to here from
9081 (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
9082 any, in the DEFALT argument into the root of the Emacs build or
9083 installation tree, as appropriate.
9085 * callproc.c (init_callproc_1): Call decode_env_path instead of
9086 doing its equivalent by hand.
9087 (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
9088 the code that sets Vexec_path run on MS-Windows.
9090 * lread.c (init_lread): Add comments to #ifdef's.
9092 * msdos.c (dos_set_window_size, IT_update_begin)
9093 (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
9094 instead of direct references.
9096 2012-08-04 Paul Eggert <eggert@cs.ucla.edu>
9098 Export DEFAULT_REHASH_* to GDB.
9099 * lisp.h (DEFAULT_REHASH_THRESHOLD, DEFAULT_REHASH_SIZE):
9100 Now constants, not macros.
9102 2012-08-03 Paul Eggert <eggert@cs.ucla.edu>
9104 Remove unnecessary casts involving pointers.
9105 These casts are no longer needed now that we assume C89 or later,
9106 since they involve casting to or from void *.
9107 * alloc.c (make_pure_string, make_pure_c_string, pure_cons)
9108 (make_pure_float, make_pure_vector):
9109 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP):

9117 * xselect.c (x_stop_queuing_selection_requests)
9118 (x_get_window_property, x_get_window_property_as_lisp_data):
9119 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
9120 Remove unnecessary pointer casts.
9121 * alloc.c (record_xmalloc): New function.
9122 * lisp.h (record_xmalloc): New decl.
9123 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9124 more like a function. This is because the pointer cast is not
9125 needed. All uses changed.
9126 * print.c (print_string, print_error_message): Avoid length recalc.
9128 Improve fix for macroexp crash with debugging (Bug#12118).
9129 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9130 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9131 not supposed to be invoked from the garbage collector.
9132 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9133 (gc_aset): New function, which is like ASET but can be
9134 used in the garbage collector.
9135 (set_hash_key, set_hash_value, set_hash_next, set_hash_hash)
9136 (set_hash_index): Use it instead of ASET.

9145 <g_b_init_create_symbolic_link>: New static flags.
9146 (globals_of_w32): Initialize them to zero.
9147 (GetSecurityInfo_Proc, CreateSymbolicLink_Proc): New typedefs.
9148 (map_w32_filename): Improve commentary. Simplify switch.
9149 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
9150 headers (most versions of MinGW w32api don't).
9151 (get_security_info, create_symbolic_link)
9152 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
9154 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks
9155 in the argument file name.

9157 GetFileAttributes fails with network-related error codes.
9158 (sys_rename): Diagnose renaming of a symlink when the user doesn't
9159 have the required privileges.
9160 (get_file_security_desc_by_name): Rename from
9161 get_file_security_desc.
9162 (stat_worker): New function, with most of the guts of 'stat', and
9163 with addition of handling of symlinks and support for 'lstat'.
9164 If possible, get file's attributes and security information by
9165 handle, not by name. Produce S_IFLNK bit for symlinks, when
9166 called from 'lstat'.
9167 (stat, lstat): New functions, call 'stat_worker'.
9168 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9169 symlinks when the underlying filesystem supports them.
9171 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9173 Fix macroexp crash on Windows with debugging (Bug#12118).
9174 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9175 checking subscripts; problem introduced with the recent
9176 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9177 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9178 since it's used in non-static inline functions now.
9180 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9181 Don't assume buffer size fits in 'int'. Remove unused local.
9183 Use C99-style 'extern inline' if available.

9195 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
9196 * alloc.c (LISP_INLINE):
9197 * buffer.c (BUFFER_INLINE):
9198 * category.c (CATEGORY_INLINE):
9199 * character.c (CHARACTER_INLINE):
9200 * charset.c (CHARSET_INLINE):
9201 * composite.c (COMPOSITE_INLINE):
9202 * dispnew.c (DISPEXTERN_INLINE):
9203 * sysdep.c (SYSTIME_INLINE):
9204 Define to EXTERN_INLINE, so that the corresponding functions
9205 are compiled into code.
9206 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
9207 (INLINE_HEADER_END): New macros.
9208 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9228 hard-coding the path separator.
9230 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9232 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9233 This how ASET and AREF are supposed to work, and makes
9234 it easier to think about future improvements. See
9235 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9236 * charset.h (set_charset_attr): New function.
9237 All lvalue-style uses of CHARSET_DECODER etc. changed to use it.
9238 * lisp.h (ASET): Rewrite so as not to use AREF in an lvalue style.

9651 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9652 enumeration constants, as PURE and HEAP are too general, and clash
9653 with other headers and sources, such as gmalloc.c and the
9654 MS-Windows system headers. All users changed.
9656 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9658 Revert last save_excursion_save and save_excursion_restore changes.
9659 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9672 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9673 arms of an 'if', not using conditional expressions; otherwise GDB
9674 complains about the types in the unevaluated arm when the argument
9675 is an integer literal.
9676 (xgetint): Simplify expression.
9677 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9678 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9679 Zaretskii in <http://bugs.gnu.org/12036#13>.
9680 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9681 needed now that we have gdb_make_enums_visible.
9682 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9683 (enum enum_USE_LSB_TAG):
9684 New enum types, packaging up enums that need to be exported to GDB.

9726 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9727 emacs.c, as this is a more-suitable home. Had this been done earlier
9728 the fix for 12036 would have avoided some of the problems noted in
9729 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9730 would have been more obvious.
9731 * emacs.c: Do not include <verify.h>; no longer needed.
9732 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9733 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9734 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

9740 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9741 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9742 not be usable in #if. This simplifies things.
9744 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9746 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

9751 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9752 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9753 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9754 Adjust to changes in lisp.h and emacs.c, by using
9755 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9756 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9757 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9758 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9759 instead of gdb_valbits.
9760 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9761 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9762 instead of gdb_array_mark_flag.
9763 (xboolvector): Get size from $->size, not $->header.size.
9764 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9765 (xreload, hook-run, hookpost-run): Remove.
9766 * emacs.c: Include <verify.h>.
9767 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9768 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9770 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9771 (gdb_USE_LSB_TAG): New enum constants.
9772 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9773 Also define these as enum constants, so they're visible to GDB.
9774 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9775 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9776 as constants, so they're visible to GDB.

9779 Now enum constants, not macros, so they're visible to GDB.
9780 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9781 more convenient now. All uses changed.
9782 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9783 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9785 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9792 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9793 add argument, tune behavior, and adjust all callers.
9795 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9797 Use typedef for EMACS_INT, EMACS_UINT.
9798 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9799 than macros. This simplifies debugging in the usual case, since
9800 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9801 and it allows expressions involving EMACS_INT casts.
9802 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9804 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9816 Adjust buffer text indirection counters at the end of Fkill_buffer.
9817 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9818 buffer is definitely dead. This should really fix an issue reported
9819 by Christoph Scholtes again. (Bug#12007).
9820 (init_buffer_once): Initialize indirection counters of
9821 buffer_defaults and buffer_local_symbols (for sanity and safety).
9823 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9825 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9826 and continuation glyphs on tooltip frames, leave them at zero.

9854 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9856 Swap buffer text indirection counters in Fbuffer_swap_text.
9857 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9858 This avoids crash reported by Christoph Scholtes at
9859 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9861 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9863 * nsmenu.m (Popdown_data): New struct.
9864 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9866 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9867 (initWithContentRect): Make imgView and contentView non-static
9868 and autorelease them. Also autorelease img and matrix (Bug#12005).
9869 (dealloc): Remove (Bug#12005).
9871 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9873 Adjust consing_since_gc when objects are explicitly freed.

9886 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9888 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9889 as it's limited by the amount of memory, not by INT_MAX.
9891 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9893 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9894 in special-event-map. See the discussion at

10617 * s/aix4-2.h (unix): Remove; no longer needed.
10619 EMACS_TIME simplification (Bug#11875).
10620 This replaces macros (which typically do not work in GDB)
10621 with functions, typedefs and enums, making the code easier to debug.
10622 The functional style also makes code easier to read and maintain.
10623 * systime.h: Include <sys/time.h> on all hosts, not just if
10624 WINDOWSNT, since 'struct timeval' is needed in general.
10625 (EMACS_TIME): Now a typedef, not a macro.

10628 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

10639 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
10640 (add_emacs_time, sub_emacs_time): New functions.
10641 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

10658 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
10659 (menu_separator_name_p):
10660 * nsmenu.m (ns_update_menubar):
10661 Prefer memcmp to strncmp when either will do.
10662 * nsterm.m: Include <ftoastr.h>.
10664 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10665 Prefer snprintf to strncpy.
10666 * nsterm.m (ns_term_init):
10667 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10668 * nsterm.m (ns_term_init):
10669 Avoid the need for strncpy, by using build_string or
10670 make_unibyte_string directly. Use dtoastr, not snprintf.
10671 * process.c (Fmake_network_process): Diagnose service names that
10672 are too long, rather than silently truncating them or creating
10673 non-null-terminated names.
10674 (Fnetwork_interface_info): Likewise, for interface names.
10675 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10676 Prefer sprintf to strncat.
10677 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10678 Prefer vsnprintf to vsprintf + strncpy.
10680 2012-07-10 Glenn Morris <rgm@gnu.org>

10688 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10689 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10690 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10691 where argument type is known to be a Lisp_Cons.

10705 (build_pure_c_string): New function, defined as static inline. This
10706 provides a better opportunity to optimize away calls to strlen when
10707 the function is called with compile-time constant argument.
10708 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10709 argument, adjust users accordingly. Use build_pure_c_string where

10712 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10713 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

10742 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10743 We include usg5-4-common.h, which defines them both.
10745 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10746 O_RDONLY already includes it).
10748 Stop ns builds setting the EMACSLOADPATH environment variable.
10749 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10750 Now it does not set EMACSLOADPATH, just returns the load-path string.
10751 * nsterm.h: Update accordingly.
10752 * lread.c [HAVE_NS]: Include nsterm.h.
10753 (init_lread) [HAVE_NS]: Use ns_load_path.

10762 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10763 (ns_init_paths): Do not set EMACSPATH.

10792 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10794 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>

10814 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10815 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10816 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
10817 * nsterm.h (ns_etc_directory): Add it.
10818 * callproc.c [HAVE_NS]: Include nsterm.h.
10819 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10821 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10823 Move marker debugging code under MARKER_DEBUG.
10824 * marker.c (MARKER_DEBUG): Move marker debugging code under
10825 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10826 for bootstrap with --enable-checking (~3x slowdown reported
10827 by Juanma Barranquero <lekktu@gmail.com>).
10828 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10830 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10832 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10833 See <http://bugs.gnu.org/11825#29>.
10835 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10837 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10838 has no font, use the frame's font. (Bug#11813)
10839 (display_line): Add commentary about displaying truncation glyphs
10841 (produce_special_glyphs): Move here from term.c.
10843 * term.c (produce_special_glyphs): Move to xdisp.c.
10845 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10848 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10850 * xdisp.c (display_line): Avoid warning about implicit declaration
10853 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10855 * lisp.h: Remove empty conditional.
10857 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10859 * lread.c (load_path_check): Now static.
10861 Fix some minor --with-ns problems found by static checking.
10862 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10863 (x_set_font) [!HAVE_X_WINDOWS]:
10864 * image.c (xpm_load_image) [HAVE_NS]:
10865 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10866 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10867 Remove unused local.
10868 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10869 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10870 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10871 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10872 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10873 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10874 Fix pointer signedness problem.
10875 * xfaces.c (FRAME_X_FONT_TABLE):
10876 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10878 2012-07-07 Glenn Morris <rgm@gnu.org>
10880 * lread.c (load_path_check): New function, split from init_lread.
10881 (init_lread): Reorganize. Motivation:
10882 If EMACSLOADPATH is set, check/warn about that rather than the
10883 defaults, which we are not going to use. Hence we can remove
10884 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10885 Don't warn if site-lisp directories are missing.
10886 If not installed, start from a blank load-path, since
10887 PATH_LOADSEARCH refers to the eventual installation directories.
10889 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10891 Support truncation and continuation glyphs on GUI frames, when
10892 fringes are disabled. (Bug#11832)
10893 * xdisp.c (init_iterator): Get dimensions of truncation and
10894 continuation glyphs even if on GUI frames.
10895 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10896 or both, are absent.
10897 (start_display, move_it_in_display_line_to): Handle the case of a
10898 GUI frame without a fringe to display continuation or truncation
10900 (insert_left_trunc_glyphs): Support GUI frames: make sure
10901 truncation glyphs overwrite enough glyphs from the current line to
10902 have sufficient space in pixels.
10903 (display_line): Support truncation and continuation glyphs on GUI
10904 frames. If some spare pixels are left on the line after inserting
10905 the truncation glyphs, fill that space with a stretch glyph of a
10906 suitably computed width.
10908 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10909 produce_glyphs, to support GUI sessions.
10911 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10913 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10915 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10917 Do not require float-time's arg to fit in time_t (Bug#11825).
10918 This works better on hosts where time_t is unsigned, and where
10919 float-time is applied to the (negative) difference between two times.
10920 * editfns.c (decode_time_components): Last arg is now double *,
10921 not int *, and means to store all the result as a double, without
10922 worrying about whether the seconds part fits in time_t.
10923 All callers changed.
10924 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10925 All callers changed.
10926 (Ffloat_time): Do not fail merely because the specified time falls
10927 outside of time_t range.
10929 2012-07-07 Glenn Morris <rgm@gnu.org>
10931 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10932 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10933 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10935 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10937 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10938 Update dependencies.

10946 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10947 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10948 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10949 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10951 * xfont.c (compare_font_names): Redo to omit the need for casts.
10953 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10955 * xfns.c (Fx_change_window_property): Doc fix.
10956 * w32fns.c (Fx_change_window_property): Doc fix.
10958 * w32fns.c (Fx_window_property): Accept the same arguments as the
10959 X Windows version. Doc fix.
10960 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10962 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10963 Eli Zaretskii <eliz@gnu.org>
10965 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10966 Windows-specific code from nt/config.nt moved here.
10967 Obsolete settings removed.
10969 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10971 * process.c: Avoid unnecessary calls to gettime.
10972 (wait_reading_process_output): Don't get the time of day
10973 when gobbling data immediately and not waiting, as there's no need
10974 for it in that case. This removes a FIXME.
10976 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10978 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10979 is defined (Bug#11768).
10981 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10983 Fix marker debugging code.
10984 * marker.c (byte_char_debug_check): Do not perform the check
10985 if buffer is not multibyte.
10986 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10987 Call byte_char_debug_check with correct arguments.
10989 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10991 Compile marker debugging code only if ENABLE_CHECKING is defined.
10992 * marker.c (byte_char_debug_check, count_markers):
10993 Use only if ENABLE_CHECKING is defined.
10994 (byte_debug_flag): Remove.
10995 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10996 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10998 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11000 Avoid code repetition in marker-related functions.
11001 * marker.c (attach_marker): New function.

11005 Consistently rename charno to charpos.
11006 (marker_position): Add eassert.
11007 (marker_byte_position): Convert to eassert.
11009 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

11023 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
11024 (save_restriction_save): Use build_marker.
11025 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
11026 * window.c (save_window_save): Likewise.
11028 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
11030 Do not use Fdelete_overlay in delete_all_overlays
11031 to avoid redundant calls to unchain_overlay.
11032 * buffer.c (drop_overlay): New function.
11033 (delete_all_overlays, Fdelete_overlay): Use it.
11034 * minibuf.c (get_minibuffer): Fix comment.
11036 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
11038 Port to OpenBSD 5.1 amd64.
11039 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
11040 This is needed for OpenBSD, and should be harmless on all BSD systems.
11041 Also, include <sys/sysctl.h>, as it should be available on all
11042 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11043 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11044 use p_pid member, not kp_proc.pid.
11046 2012-07-06 Glenn Morris <rgm@gnu.org>
11048 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11050 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11052 More xmalloc and related cleanup.

11061 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11063 Omit needless casts involving void * pointers and allocation.
11064 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11065 as the former is more robust if P's type is changed.
11066 Prefer xzalloc to xmalloc + memset 0.
11067 Simplify malloc-or-realloc to realloc.
11068 Don't worry about xmalloc returning a null pointer.
11069 Prefer xstrdup to xmalloc + strcpy.
11070 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11072 * keyboard.c (apply_modifiers_uncached): Prefer local array to

11077 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11078 hscroll is larger than the line width. Fixes long and futile
11079 looping inside extend_face_to_end_of_line (on a TTY) producing
11080 glyphs that are not needed and thrown away.
11082 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11084 * marker.c (set_marker_restricted_both): Simplify by using
11087 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

11098 followed by gtk_box_set_homogeneous (Bug#11768).
11099 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11100 (update_theme_scrollbar_width, xg_create_scroll_bar):
11101 Use gtk_scrollbar_new (Bug#11768).

11103 (is_box_type): New function (Bug#11768).
11104 (xg_tool_item_stale_p): Call is_box_type.
11105 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11106 with default display (Bug#11768).
11108 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11110 * xdisp.c (window_hscroll_limited): New function.
11111 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11112 coordinates when window's hscroll is set to insanely large
11113 values. (Bug#11857)
11115 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11179 Problem reported by Troels Nielsen in
11180 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11182 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11184 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11185 This should be fixed in a better way; see Eli Zaretskii in
11186 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11187 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11189 * fileio.c (time_error_value): Rename from special_mtime.
11190 The old name's problems were noted by Eli Zaretskii in
11191 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11193 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11194 This variable's comment says Emacs needs at least one GDB-visible
11195 symbol of type enum pvec_type, to work around GDB problems.
11196 The symbol's value doesn't matter.
11198 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11199 that causes compilation to fail on pre-C99 compilers.
11201 2012-07-04 Juanma Barranquero <lekktu@gmail.com>

11206 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11208 * buffer.c (init_buffer_once): Fix initialization of
11209 headers for buffer_defaults and buffer_local_symbols.

11230 (live_vector_p): Use PVEC_TYPE.
11231 (mark_object): Adapt code to extract pvectype. Use switch.
11233 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11235 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11236 Tighten new eassert a bit.
11238 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11240 Fix compilation with --enable-gcc-warnings and -O1
11241 optimization level.
11242 * doprnt.c (doprnt): Change type of tem to int, initialize
11243 to avoid compiler warning. Add eassert.
11244 * search.c (simple_search): Initialize match_byte to avoid
11245 compiler warning. Add eassert.

11249 Avoid weird behavior with large horizontal scrolls.
11250 Without this change, for example, large hscroll values would
11251 mess up Emacs's display on Fedora 15 x86, presumably due to
11252 overflows in int calculations in the display code.
11253 Also, if buffers had long lines, Emacs would freeze.
11254 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11255 (set_window_hscroll): New function, containing the old guts of
11256 Fset_window_hscroll. Return the clipped value.
11257 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11258 This avoids the need to check against PTRDIFF_MAX.
11260 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11262 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11264 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11266 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11268 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11269 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11270 since GCC 4.4.6 issues a bogus warning for them.
11272 Fix bugs in file timestamp newness comparisons.
11273 * fileio.c (Ffile_newer_than_file_p):
11274 * lread.c (Fload): Use full timestamp resolution of files,
11275 not just the 1-second resolution, so that files that are only
11276 slightly newer still count as newer.
11277 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11278 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11280 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11282 * fileio.c: Improve handling of file time marker. (Bug#11852)
11283 (special_mtime): New function.
11284 (Finsert_file_contents, Fverify_visited_file_modtime):
11285 Use it to set special mtime values consistently.
11287 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11289 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11290 marker for non-existing file. (Bug#11852)
11292 2012-07-03 Glenn Morris <rgm@gnu.org>
11294 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11295 and did not make it into globals.h).
11297 2012-07-03 Tom Tromey <tromey@redhat.com>
11299 * window.c (Fset_window_margins, Fset_window_fringes)
11300 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
11301 * textprop.c (Fprevious_property_change): No longer static.
11302 * syntax.c (Fsyntax_table_p): No longer static.
11303 * process.c (Fget_process, Fprocess_datagram_address): No longer
11305 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
11306 * keyboard.c (Fcommand_execute): No longer static.

11326 * font.h: Remove EXFUNs.
11327 * dosfns.c (system_process_attributes): Remove EXFUN.
11328 * keymap.h: Remove EXFUNs.
11329 * lisp.h: Remove EXFUNs.
11330 * w32term.h: Remove EXFUNs.
11331 * window.h: Remove EXFUNs.
11332 * xsettings.h: Remove EXFUN.
11333 * xterm.h: Remove EXFUN.
11335 2012-07-03 Glenn Morris <rgm@gnu.org>
11337 * lisp.h (Frandom): Make it visible to C.
11338 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11339 buffer for invisible buffers. (Bug#1229)
11341 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11343 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11344 values which aren't power of 2.
11345 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11346 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11349 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11351 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11353 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11355 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11357 * alloc.c (allocate_vector_block): Remove redundant
11358 calls to mallopt if DOUG_LEA_MALLOC is defined.
11359 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11360 avoid calls to mallopt if zero_vector is returned.
11362 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11364 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11365 is enabled, avoid dereferencing NULL current_sblock if
11368 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11370 Cleanup basic buffer management.
11371 * buffer.h (struct buffer): Change layout to use generic vector
11372 marking code. Fix some comments. Change type of 'clip_changed'
11373 to bitfield. Remove unused #ifndef old.
11374 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11375 (GET_OVERLAYS_AT): Fix indentation.
11376 (for_each_per_buffer_object_at): New macro.
11377 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
11378 (Fbuffer_local_variables): Use it.
11379 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
11380 * alloc.c (allocate_buffer): Adjust to match new layout of
11381 struct buffer. Fix comment.
11382 (mark_overlay): New function.
11383 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11384 Lisp area of struct buffer.
11385 (mark_object): Use it. Adjust marking of misc objects
11386 and related comments.
11388 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11390 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11391 wrapper that is not needed because the wrapped code is a no-op (zero
11392 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11393 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11395 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11397 * alloc.c (mark_buffer): Simplify. Remove prototype.
11398 (mark_object): Add comment. Reorganize marking of vector-like
11399 objects. Use CHECK_LIVE for all vector-like objects except buffers
11400 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11401 Avoid redundant calls to mark_vectorlike for bool vectors.
11403 2012-06-30 Glenn Morris <rgm@gnu.org>
11405 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11407 * epaths.in (PATH_SITELOADSEARCH): New.
11408 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11409 This is rather than relying on --enable-locallisppath elements
11410 having "site-lisp" in their names. (Bug#10208#25, 11658)
11412 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11414 * w32proc.c (sys_select): Accept and ignore one more argument.
11416 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11418 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11419 (pselect) [!MS_DOS]: Redirect to sys_select.
11421 * sysdep.c: Don't include dos.h and dosfns.h.
11423 * process.c (sys_select):
11424 * msdos.c (sys_select): Accept one more argument and ignore it.
11426 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11427 adapt data types and code to that.
11430 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11431 which clashes with the gnulib function of the same name.
11433 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11435 * font.c (font_style_to_value, font_style_symbolic)
11436 (font_prop_validate_style): Add type checks for values in
11439 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11441 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11444 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11446 * xdisp.c (try_window_id): Undo last change.
11448 * w32.c (getwd): Adjust commentary about startup_dir.
11449 (init_environment): Always call sys_access, even in non-MSVC
11450 builds. Don't chdir to the directory of the Emacs executable.
11451 This undoes code from 1997 which was justified by the need to
11452 "avoid conflicts when removing and renaming directories". But its
11453 downside was that every relative file name was being interpreted
11454 relative to the directory of the Emacs executable, which can never
11455 be TRT. In particular, it broke sys_access when called with
11456 relative file names.
11457 (sys_access): Map GetLastError to errno.
11459 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11461 * window.h (struct window): Change type of 'fringes_outside_margins'
11462 to bitfield. Fix comment. Adjust users accordingly.
11463 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11465 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11468 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11470 * gnutls.c (emacs_gnutls_handshake):
11471 Add QUIT to make the loop interruptible.
11473 2012-06-29 Glenn Morris <rgm@gnu.org>
11475 * charset.c (init_charset): Make lack of etc/charsets fatal.
11477 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11479 * editfns.c (region_limit): Fix type mismatch.
11481 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11483 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11484 undefined. Convert from xassert to eassert.
11485 * nsmenu.m: Convert from xassert to eassert.
11486 * nsterm.m: Likewise.
11488 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11490 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11492 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11494 Avoid integer overflow on scroll-left and scroll-right.
11495 * window.c (HSCROLL_MAX): New macro.
11496 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11497 overflow when requested scroll falls outside ptrdiff_t range.
11499 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11501 * window.h (struct window): Change type of 'hscroll',
11502 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11503 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11504 Adjust users accordingly.
11505 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11506 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11507 from EMACS_INT to ptrdiff_t.

11527 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11528 adjust comments accordingly.

11649 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11651 Use sprintf return value instead of invoking strlen on result.
11652 In the old days this wasn't portable, since some sprintf
11653 implementations returned char *. But they died out years ago and
11654 Emacs already assumes sprintf returns int.
11655 Similarly for float_to_string.
11656 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
11657 * ccl.c (ccl_driver):

11661 * print.c (print_object):
11662 * xdisp.c (message_dolog):
11663 * xfns.c (syms_of_xfns):
11664 Use sprintf or float_to_string result to avoid need to call strlen.
11665 * data.c (Fnumber_to_string):
11666 Use make_unibyte_string, since the string must be ASCII.
11667 * lisp.h, print.c (float_to_string): Now returns int length.
11668 * term.c (produce_glyphless_glyph):
11669 Use sprintf result rather than recomputing it.
11671 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11672 * Makefile.in (ALL_CFLAGS):
11673 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

11679 strcasecmp if available.

11698 sprintf already null-terminates its output.
11700 * xfns.c (x_window): Remove redundant cast.
11702 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11704 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11705 `const char *' to `char *' to avoid compiler warning.
11707 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11709 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11710 instead of truncating it to 63 (admittedly a generous limit).
11712 * process.c: Fix spelling and caps in comments.
11714 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11716 * emacs.c (setpgrp): Remove definition, unused.

11806 language ID in the event parameters.
11808 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11809 event.code, not the obscure "character set ID".

11840 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11842 Support higher-resolution time stamps (Bug#9000).
11843 The time stamps are only nanosecond-resolution at the C level,
11844 since that's the best that any real-world system supports now.
11845 But they are picosecond-resolution at the Lisp level, as that's
11846 easy, and leaves room for future OS improvements.
11848 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11851 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11852 Don't get current time unless it's needed.
11854 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11855 now provides it if it's absent.
11856 (start_atimer): Port to higher-res time stamps.
11857 Check for time stamp overflow. Don't get current time more
11858 often than is needed.
11860 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11861 Include systime.h, not time.h.
11862 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11864 * dired.c: Include stat-time.h.
11865 (Ffile-attributes): File times now have higher resolution.
11867 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11868 (struct image): Timestamp now has higher resolution.
11870 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11871 has at least microseconds now. All uses removed.
11872 (update_frame, update_single_window, update_window, update_frame_1)
11873 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11874 (duration_to_sec_usec): Remove; no longer needed.
11876 * editfns.c (time_overflow): Now extern.
11877 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

11882 (decode_time_components, lisp_seconds_argument): New functions.
11883 (make_time): Now static.
11884 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11885 Report an error if the time is invalid, rather than having the caller
11888 * fileio.c: Include <stat-time.h>
11889 (Fcopy_file): Copy higher-resolution time stamps.
11890 Prefer to set the time stamp via a file descriptor if that works.
11891 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11892 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11893 (Fvisited_file_modtime, Fset_visited_file_modtime):
11894 Support higher-resolution time stamps.
11896 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11898 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11900 * image.c (prepare_image_for_display, clear_image_cache)
11901 (lookup_image): Port to higer-resolution time stamps.
11903 * keyboard.c (start_polling, bind_polling_period):
11904 Check for time stamp overflow.
11905 (read_char, kbd_buffer_get_event, timer_start_idle)
11906 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11907 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11908 Port to higher-resolution time stamps. Do not assume time_t is signed.
11909 (decode_timer): New function. Timers are now vectors of length 9,
11910 not 8, to accommodate the picosecond component.
11911 (timer_check_2): Use it.
11913 * nsterm.m (select_timeout, timeval_subtract): Remove.
11914 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11915 as they're a bit more accurate and handle overflow better.
11916 (ns_select): Change prototype to be compatible with pselect.
11917 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11918 * nsterm.h (ns_select): Adjust prototype.
11920 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11921 us-resolution time stamps.
11922 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11924 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11926 * lisp.h (time_overflow): New decl.
11927 (wait_reading_process_output): First arg is now intmax_t, not int,
11928 to accommodate larger waits.
11930 * process.h (struct Lisp_Process.read_output_delay):
11931 Now counts nanoseconds, not microseconds.
11932 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11934 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11935 (wait_reading_process_output):
11936 Port to ns-resolution time stamps.
11937 (Faccept_process_output, wait_reading_process_output):
11938 Check for time stamp overflow. Do not assume time_t is signed.
11939 (select_wrapper): Remove; we now use pselect.
11940 (Fprocess_attributes): Now generates ns-resolution time stamps.
11942 * sysdep.c: Include utimens.h. Don't include utime.h
11943 or worry about struct utimbuf; gnulib does that for us now.
11944 (gettimeofday): Remove; gnulib provides a substitute.
11945 (make_timeval): New function.
11946 (set_file_times): Now sets ns-resolution time stamps.
11947 New arg FD; all uses changed.
11948 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11949 (system_process_attributes):
11950 Now returns ns-resolution time stamp. All uses changed.
11951 Check for time stamp overflow.
11953 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11954 provides a substitute now.
11956 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11957 since it guarantees struct timespec.
11958 (EMACS_TIME): Now struct timespec, so that we can support
11959 ns-resolution time stamps.
11960 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11961 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11962 (EMACS_USECS): Remove.
11963 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11964 so multiply the arg by 1000 before storing it.
11965 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11967 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11968 Port to ns-resolution time stamps.
11969 (EMACS_TIME_NEG_P): Remove; replaced by....

11974 (make_timeval, make_lisp_time, decode_time_components): New decls.
11975 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11976 that it mishandled time_t overflow. You can't compare by subtracting!
11977 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11978 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11980 * term.c: Include <sys/time.h>.
11981 (timeval_to_Time): New function, for proper overflow wraparound.
11982 (term_mouse_position, term_mouse_click): Use it.
11984 * undo.c (record_first_change): Support higher-resolution time stamps
11985 in the undo buffer.
11986 (Fprimitive_undo): Use them when restoring time stamps.
11988 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11989 (w32_get_internal_run_time):
11990 Port to higher-resolution Emacs time stamps.
11991 (ltime): Now accepts single 64-bit integer, as that's more convenient
11994 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11996 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11997 for compatibility with pselect. Support ns-resolution time stamps.
11999 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
12001 * xselect.c (wait_for_property_change, x_get_foreign_selection):
12002 Check for time stamp overflow, and support ns-resolution time stamps.
12004 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
12005 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
12006 (timeval_subtract): Remove; no longer needed.
12007 (XTflash, XTring_bell, x_wait_for_event):
12008 Port to ns-resolution time stamps. Don't assume time_t is signed.

12014 2012-06-22 Eli Zaretskii <eliz@gnu.org>
12016 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
12017 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
12018 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
12019 staticidx goes up to 1597 out of 1600 = 0x640.)
12021 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
12023 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

12035 access to `contents' member of Lisp_Vector objects with AREF and ASET
12038 2012-06-19 Chong Yidong <cyd@gnu.org>
12040 * frame.c (delete_frame): When selecting a frame on a different
12041 text terminal, do not alter the terminal's top-frame.

12044 frame's selected window and its terminal's top-frame.
12045 (unwind_format_mode_line): Restore them.
12046 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
12048 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
12049 since tty frames can be explicitly named.
12050 (prepare_menu_bars): Likewise.
12052 * term.c (Ftty_top_frame): New function.
12054 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

12057 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
12058 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
12059 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
12060 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

12067 2012-06-18 Martin Rudalics <rudalics@gmx.at>
12069 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
12070 gets killed during executing of this function (Bug#11665).
12071 Try to always return Qt when the buffer has been actually killed.
12072 (Vkill_buffer_query_functions): In doc-string say that functions
12073 run by this hook should not change the current buffer.
12075 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12077 Fix recently-introduced process.c problems found by static checking.
12078 * process.c (write_queue_push, write_queue_pop, send_process):
12079 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
12080 (write_queue_pop): Fix pointer signedness problem.
12081 (send_process): Remove unused local.
12083 2012-06-17 Chong Yidong <cyd@gnu.org>

12097 * lisp.h (eassert): Assume C89 or later.
12098 This removes the need for CHECK.
12099 (CHECK): Remove. Its comments about always evaluating its
12100 argument were confusing, as 'eassert' typically does not evaluate
12103 * coding.c (produce_chars): Use ptrdiff_t, not int.
12105 * xterm.c (x_draw_underwave): Check for integer overflow.
12106 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

12204 indexing into it->string_overlays array. (Bug#11653)
12205 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not

12280 * alloc.c (make_number) [!defined make_number]:
12281 Remove, as lisp.h always defines this now.

12292 as the union type is for debugging, not for production.
12293 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12294 Use an inline function on all platforms when using the union type,
12295 since this is simpler and 'static inline' can be used portably

12298 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
12299 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

12402 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
12404 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12406 * alloc.c (allocate_vectorlike): Fix last change.

12439 * doprnt.c (doprnt): Truncate multibyte char correctly.
12440 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12441 would mishandle a string argument "Xc" if X was a multibyte
12442 character of length 2: it would truncate after X's first byte
12443 rather than including all of X.
12445 2012-06-06 Chong Yidong <cyd@gnu.org>
12447 * buffer.c (word_wrap): Doc fix.

12494 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12496 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12497 Convert pctcpu and pctmem to Lisp float properly.
12498 Let the compiler fold better, as 100.0/0x8000 is exact.
12500 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12502 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of

12512 bitfields where appropriate, remove unused fields.
12513 * window.h (struct window): Remove unused 'last_mark_x' and
12514 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12515 change its type from Lisp_Object to bitfield.
12516 Change type of 'force_start', 'optional_new_start',
12517 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

12524 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12525 Use 'float' consistently, rather than 'float' in most places
12526 and 'double' in a couple of places.
12528 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12530 * xdisp.c (handle_stop): Detect whether we have overlay strings
12531 loaded by testing it->current.overlay_string_index to be
12532 non-negative, instead of checking whether n_overlay_strings is
12533 positive. (Bug#11587)
12535 2012-05-31 Chong Yidong <cyd@gnu.org>
12537 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12543 * search.c (search_buffer): Remove calls to
12544 r_alloc_inhibit_buffer_relocation, as it is now called by

12550 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12551 for the duration of call to load_charset, to avoid problems with
12552 callers of maybe_unify_char that access buffer text through C
12555 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12556 decrement the inhibition flag, instead of just setting or
12559 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12561 Remove obsolete '#define static' cruft.
12562 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12563 This #undef was "temporary" in 2000; it is no longer needed
12564 now that '#define static' has gone away.

12579 (safe_bcopy): Remove decl; no longer has that name.
12580 (main): Coalesce #if into single bit of code, for simplicity.

12611 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12612 Bug#9642, but explicitly check that the buffer the overlay would
12613 be moved to is live and rearrange lines to make sure that errors
12614 will not put the overlay in an inconsistent state.
12615 (Fdelete_overlay): Cosmetics.
12617 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12619 * w32term.c (my_bring_window_to_top): New function.

12631 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12633 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12634 This avoids undefined behavior that might cause the eassert
12635 to not catch an out-of-range value.
12637 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12639 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
12640 Update dependencies.
12642 2012-05-27 Eli Zaretskii <eliz@gnu.org>

12649 when referring to sectname field in printf format.
12651 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12653 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12654 Only r_alloc_inhibit_buffer_relocation needed to be added;
12655 the others were already declared.
12657 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12658 before checking whether it's out of range. Put the check inside
12660 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12662 2012-05-27 Ken Brown <kbrown@cornell.edu>
12664 * callproc.c (Fcall_process): Restore a line that was accidentally
12665 commented out in the 2011-02-13 change (bug#11547).
12667 2012-05-27 Eli Zaretskii <eliz@gnu.org>
12669 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12670 defined on ralloc.c.
12672 * buffer.c [REL_ALLOC]: Remove prototypes of
12673 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12674 they are now on lisp.h.
12676 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12678 * search.c (search_buffer): Use it to inhibit relocation of buffer
12679 text while re_search_2 is doing its job, because re_search_2 is
12680 passed C pointers to buffer text. (Bug#11519)
12682 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12683 Update value to 24.
12685 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12686 state after an additional call to move_it_in_display_line_to, keep
12687 the values of it->max_ascent and it->max_descent found for the
12689 (pos_visible_p): Revert the comparison against bottom_y to what it
12690 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12693 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12695 Fix coding-related core dumps with gcc -ftrapv.
12696 The code was computing A - B, where A and B are pointers, and B is
12697 random garbage. This can lead to core dumps on platforms that
12698 have special pointer registers, and it also leads to core dumps on
12699 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12700 A - B only when B is initialized properly.
12701 * coding.c (coding_set_source, coding_set_destination): Return void.
12702 (coding_change_source, coding_change_destinations): New functions,
12703 with the old behaviors of coding_set_source and coding_set_destination.
12704 All callers that need an offset changed to use these new functions.
12706 2012-05-26 Glenn Morris <rgm@gnu.org>
12708 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
12710 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12712 Extend mouse support on W32 text-mode console.
12713 * xdisp.c (draw_row_with_mouse_face):
12714 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12716 * w32console.c: Include window.h.
12717 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12719 (initialize_w32_display): Initialize mouse-highlight data.
12721 * w32inevt.c: Include termchar.h and window.h.
12722 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12723 moves, call note_mouse_highlight. If help_echo changed, call
12724 gen_help_event to produce help-echo message in the echo area.
12725 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12728 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12730 * lread.c (read1): Simplify slightly to avoid an overflow warning
12731 with GCC 4.7.0 on x86-64.
12733 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12735 * bidi.c (bidi_mirror_char): Revert last change: an int is
12736 definitely wide enough here.
12738 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12740 Fix integer width and related bugs (Bug#9874).

12750 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12751 (allocate_pseudovector):
12752 Use int, not EMACS_INT, where int is wide enough.
12753 (inhibit_garbage_collection, Fgarbage_collect):
12754 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12755 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12756 int might not be wide enough.
12757 (bidi_cache_search, bidi_cache_find, bidi_init_it)

12772 (Foverlay_recenter, last_overlay_modification_hooks_used)
12773 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12774 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12775 (validate_region): Omit unnecessary test for b <= e,
12776 since that's guaranteed by the previous test.
12777 (adjust_overlays_for_delete): Avoid pos + length overflow.
12778 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12779 (report_overlay_modification):
12780 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12781 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12782 Omit pointer cast, which isn't needed anyway, and doesn't work
12783 after the EMACS_INT -> ptrdiff_t change.
12784 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12785 * buffer.h: Adjust decls to match defn changes elsewhere.
12786 (struct buffer_text, struct buffer):
12787 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12788 Use EMACS_INT, not int, where int might not be wide enough.
12789 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12790 not int, to avoid needless 32-bit limit on 64-bit hosts.
12791 (exec_byte_code): Use tighter memory-full test, one that checks
12792 for alloca overflow. Don't compute the address of the object just
12793 before an array, as that's not portable. Use EMACS_INT, not
12794 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12795 * callint.c (Fcall_interactively):
12796 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12797 * callproc.c (call_process_kill, Fcall_process):
12798 Don't assume pid_t fits into an Emacs fixnum.
12799 (call_process_cleanup, Fcall_process, child_setup):

12807 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
12808 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12809 (casify_object): Avoid integer overflow when overallocating buffer.
12810 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12811 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12812 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12813 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12814 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12815 integers are now checked earlier. All uses replaced with XINT.
12817 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12818 For CCL_MapSingle, check that content and value are in int range.
12819 (ccl_driver, Fregister_code_conversion_map):
12820 Check that Vcode_version_map_vector is a vector.
12821 (resolve_symbol_ccl_program): Check that vector header is in range.
12822 Always copy the vector, so that we can check its contents reliably
12823 now rather than having to recheck each instruction as it's being
12824 executed. Check that vector words fit in 'int'.
12825 (ccl_get_compiled_code, Fregister_ccl_program)
12826 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12827 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12828 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12829 contents are in range.
12830 (Fccl_execute_on_string): Check that status is in range.
12831 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12832 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12833 Accept and return EMACS_INT, not int, because callers can pass values
12834 out of 'int' range.

12840 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12841 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12842 avoid mishandling large integers.
12843 * character.h: Adjust decls to match defn changes elsewhere.
12844 * charset.c (load_charset_map_from_file, find_charsets_in_text)

12849 Don't assume fixnum fits in int.
12850 (load_charset_map_from_vector, Fmap_charset_chars):
12851 Remove now-unnecessary CHECK_NATNUMs.
12852 (Fdefine_charset_internal): Check ranges here, more carefully.
12853 Don't rely on undefined behavior with signed left shift overflow.
12854 Don't assume unsigned int fits into fixnum, or that fixnum fits
12855 into unsigned int. Don't require max_code to be a valid fixnum;
12856 that's not true for gb10830 4-byte on a 32-bit host. Allow
12857 invalid_code to be a cons, for the same reason. Require code_offset
12858 to be a character. Avoid int overflow if max_char is close
12860 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12861 this is intended anyway and avoids some undefined behavior.
12862 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12863 INDEX_TO_CODE_POINT, as that's what it expects.
12864 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12865 * charset.h (DECODE_CHAR): Return int, not unsigned;
12866 this is what was intended anyway, and it avoids undefined behavior.
12867 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12868 integer-overflow issues.
12869 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12870 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12871 where the argument is EMACS_INT, and this behavior is not intended.
12872 * chartab.c (Fmake_char_table, Fset_char_table_range)
12873 (uniprop_get_decoder, uniprop_get_encoder):
12874 Don't assume fixnum fits in int.
12875 * cmds.c (move_point): New function, that does the gist of
12876 Fforward_char and Fbackward_char, but does so while checking
12877 for integer overflow more accurately.
12878 (Fforward_char, Fbackward_char): Use it.
12879 (Fforward_line, Fend_of_line, internal_self_insert)
12880 (internal_self_insert):
12881 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12941 Do not attempt to compute the address of the object just before a

13691 position. Don't increment display vector index past the end of
13692 the display vector. (Bug#11417)
13693 (pos_visible_p): Don't report a position visible when move_it_to
13694 stopped at the last line of window, which happens to be scanned
13695 backwards by the bidi iteration. (Bug#11464)
13697 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13699 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13700 and right-margin display specs even if the spec is invalid or we
13701 are on a TTY, and thus unable to display on the fringes.
13702 That's because the text with the property will not be displayed anyway,
13703 so we need to signal to the caller that this is a "replacing"
13704 display spec. This fixes display when the spec is invalid or we
13707 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13709 * unexaix.c (make_hdr): Fix typo in prototype.
13710 This bug broke the build on AIX. Problem reported by Gilles Pion.
13712 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13714 * keyboard.c (kbd_buffer_get_event): Read special events also in
13715 batch mode. (Bug#11415)
13717 2012-05-12 Glenn Morris <rgm@gnu.org>
13719 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13721 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13723 * lisp.mk (lisp): Add newcomment.elc.
13725 2012-05-12 Glenn Morris <rgm@gnu.org>
13727 * Makefile.in (MKDIR_P): New, set by configure.
13728 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13730 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13732 Remove unused function hourglass_started.
13733 * dispextern.h (hourglass_started):
13734 * w32fns.c (hourglass_started):
13735 * xdisp.c (hourglass_started): Remove.
13737 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13739 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13740 Update dependencies.
13742 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13744 * xgselect.c (xg_select): Put maxfds+1 into a var.
13745 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13747 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13749 2012-05-10 Dave Abrahams <dave@boostpro.com>
13751 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13752 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13754 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13756 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13757 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13758 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13759 Initialize xd_registered_buses.
13761 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13763 Untag more efficiently if USE_LSB_TAG.
13764 This is based on a proposal by YAMAMOTO Mitsuharu in
13765 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13766 For an admittedly artificial (nth 8000 longlist) benchmark on
13767 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13768 Emacs's overall text size by 1%.
13769 * lisp.h (XUNTAG): New macro.
13770 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13771 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13772 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13773 * eval.c (Fautoload):
13774 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13775 * frame.h (XFRAME): Use XUNTAG.
13777 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13778 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13779 Remove unportable assumptions about print widths of types like
13781 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13782 intptr_t when converting between pointer and integer, to avoid GCC
13783 warnings about wrong width.
13785 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13787 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13788 stack for each reader_thread, instead of defaulting to 8MB
13789 determined by the linker. This avoids failures in creating
13790 subprocesses on Windows 7, see the discussion in this thread:
13791 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13793 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13795 Fix up display of the *Minibuf-0* buffer in the mini window.
13796 * keyboard.c (read_char): Don't clear the echo area if there's no
13798 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13799 contents of *Minibuf-0*) if there's no message displayed in its stead.
13801 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13803 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13806 2012-05-06 Chong Yidong <cyd@gnu.org>
13808 * lisp.mk (lisp): Update.
13810 2012-05-05 Jim Meyering <meyering@redhat.com>
13812 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13814 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13816 * data.c (PUT_ERROR): New macro.
13817 (syms_of_data): Use it. Add new error type `user-error'.
13818 * undo.c (user_error): New function.
13819 (Fprimitive_undo): Use it.
13820 * print.c (print_error_message): Adjust print style for `user-error'.
13821 * keyboard.c (user_error): New function.
13822 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13824 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13826 Do not limit current-time-string to years 1000..9999.
13827 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13828 (Fcurrent_time_string): Support any year that is supported by the
13829 underlying localtime representation. Don't use asctime, as it
13830 has undefined behavior for years outside the range -999..9999.
13832 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13834 Fix race conditions involving setenv, gmtime, localtime, asctime.
13835 Without this fix, interrupts could mess up code that uses these
13836 nonreentrant functions, since setting TZ invalidates existing
13837 tm_zone or tzname values, and since most of these functions return
13838 pointers to static storage.
13839 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13840 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13841 Grow the critical sections to include not just invoking
13842 localtime/gmtime, but also accessing these functions' results
13843 including their tm_zone values if any, and any related TZ setting.
13844 (format_time_string): Last arg is now struct tm *, not struct tm **,
13845 so that the struct tm is saved in the critical section.
13846 All callers changed. Simplify allocation of initial buffer, partly
13847 motivated by the fact that memory allocation needs to be outside
13848 the critical section.
13850 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13852 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13853 with RESET_INTERVAL.
13855 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13856 Remove duplicated buffer name initialization.
13858 2012-05-02 Jim Meyering <jim@meyering.net>
13860 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13862 * xfns.c (x_window): Use xstrdup (Bug#11375).
13864 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13866 * xdisp.c (pos_visible_p): If already at a newline from the
13867 display string before the 'while' loop, don't walk back the glyphs
13868 from it3.glyph_row. Solves assertion violation when the display
13869 string begins with a newline (egg.el). (Bug#11367)
13871 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13873 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13876 2012-05-01 Glenn Morris <rgm@gnu.org>
13878 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13879 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13880 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13881 All were removed before 23.1.
13883 * dispnew.c: Remove HAVE_LIBNCURSES test;
13884 it is always true on relevant platforms.
13886 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13887 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13889 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13891 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13893 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13894 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13897 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13899 Do not avoid creating empty evaporating overlays (Bug#9642).
13900 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13901 That is, do not delete an evaporating overlay if it becomes
13902 empty after its bounds are adjusted to fit within its buffer.
13903 This fix caused other problems, and I'm reverting it until we get
13904 to the bottom of them.
13906 2012-04-27 Chong Yidong <cyd@gnu.org>
13908 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13910 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13912 * xdisp.c (pos_visible_p): If the window start position is beyond
13913 ZV, start the display from buffer beginning. Prevents assertion
13914 violation in init_iterator when the minibuffer window is scrolled
13915 via the scroll bar.
13917 * window.c (window_scroll_pixel_based): Likewise.
13919 2012-04-27 Chong Yidong <cyd@gnu.org>
13921 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13923 2012-04-27 Glenn Morris <rgm@gnu.org>
13925 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13926 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13928 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13930 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13931 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13933 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13935 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13936 display element, check also the underlying string or buffer
13937 character. (Bug#11341)
13939 * w32menu.c: Include w32heap.h.
13940 (add_menu_item): If the call to AppendMenuW (via
13941 unicode_append_menu) fails, disable Unicode menus only if we are
13942 running on Windows 9X/Me.
13944 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13946 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13947 (xgetint): Add missing shift for LSB tags.
13949 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13951 * keyboard.c (read_char): Don't wipe echo area for select window
13952 events: These might get delayed via `mouse-autoselect-window'
13955 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13957 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13958 manipulation of :loaded-from data.
13960 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13962 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13963 now a cons (bug#11311).
13965 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13967 Do not create empty overlays with the evaporate property (Bug#9642).
13968 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13969 if it becomes empty after its bounds are adjusted to fit within
13970 its buffer. Without this fix, in a nonempty buffer (let ((o
13971 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13972 yields an empty overlay that has the evaporate property, which is
13973 not supposed to happen.
13975 Fix minor GTK3 problems found by static checking.
13976 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13977 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13978 (struct _EmacsFixedClass, emacs_fixed_get_type):
13979 Move decls here from emacsgtkfixed.h, since they needn't be public.
13980 (emacs_fixed_get_type): Now static.
13981 (emacs_fixed_class_init): Omit unused local.
13982 (emacs_fixed_child_type): Remove; unused.
13983 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13984 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13985 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13986 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13987 (EMACS_FIXED_GET_CLASS): Remove; unused.
13988 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13990 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13991 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13993 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13995 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13996 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13997 (__malloc_size_t, __malloc_ptrdiff_t):
13998 Remove. All uses removed, replaced by the definiens if needed,
13999 since we can assume C89 or better now.
14000 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

14007 (special_realloc, _realloc_internal_nolock, _realloc_internal)
14008 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
14009 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
14010 Define using prototypes, not old style.
14011 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
14012 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
14013 (align): Don't assume that signed integer overflow wraps around.
14014 Omit unused local var.
14015 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

14017 Omit no-longer-needed casts.
14018 (valloc): Use getpagesize, not __getpagesize.
14019 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
14020 (struct hdr): The 'magic' member is now size_t, not unsigned long.
14022 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
14024 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
14026 Move functions from C to Lisp. Make non-blocking method calls
14027 the default. Implement further D-Bus standard interfaces.

14057 (Fdbus_method_return_internal, Fdbus_method_error_internal)
14058 (Fdbus_send_signal, Fdbus_register_service)
14059 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

14071 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
14072 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
14073 Do not assume ptrdiff_t is the same width as 'int'.
14075 * alloc.c: Handle unusual debugging option combinations.
14076 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
14077 since the two debugging options are incompatible.
14078 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
14080 (mem_init, mem_insert, mem_insert_fixup):
14081 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

14088 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
14090 * sysdep.c [__FreeBSD__]: Minor cleanups.
14091 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14092 Use Emacs indenting style more consistently. Avoid some casts.
14093 Use 'double' consistently rather than mixing 'float' and 'double'.
14095 2012-04-21 Eduard Wiebe <usenet@pusto.de>
14097 * sysdep.c (list_system_processes, system_process_attributes):

14111 * print.c (print_preprocess): Only check print_depth if print-circle
14113 (print_object): Check for cycles even when print-circle is nil and

14133 (try_cursor_movement): If inside continuation line, don't back up
14134 farther than the first row after the header line, if any.
14135 Don't consider the header-line row as "partially visible", even if
14136 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)

14147 * Makefile.in (C_WARNINGS_SWITCH): Remove.
14148 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
14149 (ALL_CFLAGS): Use new macros rather than old.
14150 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
14151 * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
14152 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
14153 -Wunused-result, -Wunused-variable. This should go away once
14154 the Emacs and Gnulib regex code is merged.
14155 (xmalloc, xrealloc): Now static.
14157 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>

14174 New extern decls, to avoid calling undeclared functions.
14175 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14176 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14177 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14178 (NEED_MEM_INSERT): New macro.
14179 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14180 Remove one incorrect comment and fix another.
14182 Fix minor ralloc.c problems found by static checking.
14183 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

14194 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
14195 Remove decls. This fixes an "It stinks!".
14197 * alloc.c (which_symbols): Fix alignment issue / type clash.
14199 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14201 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
14202 (struct Lisp_Misc_Any): Likewise.
14203 (struct Lisp_Free): Likewise.
14204 * alloc.c (union aligned_Lisp_Symbol): Define.

14212 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
14214 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
14215 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
14216 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14217 * s/netbsd.h, s/sol2-6.h:
14218 Remove definition of GC_MARK_STACK, since the default now works.
14219 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14220 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14221 no longer the default.
14222 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14224 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14226 * lread.c (lisp_file_lexically_bound_p):
14227 Fix hang at ";-*-\n" (bug#11238).
14229 2012-04-14 Eli Zaretskii <eliz@gnu.org>
14231 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row
14232 "unchanged" if its end.pos is beyond ZV. (Bug#11199)

14241 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
14243 2012-04-13 Reuben Thomas <rrt@sc3d.org>
14245 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14247 2012-04-11 Daniel Colascione <dancol@dancol.org>
14249 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14250 against is gone. It's better to use vfork now so that when Cygwin
14251 gains a new, working vfork, we use it automatically (bug#10398).
14253 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
14255 * window.c (save_window_save): Obey window-point-insertion-type.

14271 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
14273 * w32.c (w32_delayed_load): Record the full path of the library
14274 being loaded (bug#10424).
14276 2012-04-09 Glenn Morris <rgm@gnu.org>
14278 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14279 not just in the obarray, before snarfing them. (Bug#11036)
14281 * Makefile.in ($(leimdir)/leim-list.el):
14282 Pass EMACS rather than BUILT_EMACS.
14284 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
14286 * process.c (make_process):
14287 * process.h: Add integer `gnutls_handshakes_tried' member to
14290 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
14291 Add convenience `GNUTLS_LOG2i' macro.
14293 * gnutls.c (gnutls_log_function2i): Convenience log function.
14294 (emacs_gnutls_read): Use new log functions,
14295 `gnutls_handshakes_tried' process member, and
14296 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14297 attempts per process (connection).
14299 2012-04-09 Chong Yidong <cyd@gnu.org>
14301 * eval.c (Fuser_variable_p, user_variable_p_eh)
14302 (lisp_indirect_variable): Functions deleted.
14303 (Fdefvar): Caller changed.
14305 * callint.c (Finteractive, Fcall_interactively):
14306 * minibuf.c (Fread_variable): Callers changed.
14308 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14310 * xdisp.c (set_cursor_from_row): If the display string appears in
14311 the buffer at position that is closer to point than the position
14312 after the display string, display the cursor on the first glyph of
14313 the display string. Fixes cursor display when a 'display' text
14314 property immediately follows invisible text. (Bug#11094)
14316 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14318 composite.c: use 'double' consistently
14319 * composite.c (get_composition_id): Use 'double' consistently
14320 instead of converting 'float' to 'double' and vice versa; this is
14321 easier to understand and avoids a GCC warning.
14323 2012-04-09 Glenn Morris <rgm@gnu.org>
14325 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14326 preparation for dumping it with emacs. (Bug#4789)
14327 (leimdir): New variable.
14328 ($(leimdir)/leim-list.el): New rule.
14329 (emacs$(EXEEXT)): Depend on leim-list.el.

14347 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14348 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14349 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14350 objects, as mark_maybe_pointer will catch them otherwise.
14351 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
14352 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

14359 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14361 Support building on MS-Windows with libxml2.
14363 * makefile.w32-in (OBJ2): Add xml.$(O).
14364 (GLOBAL_SOURCES): Add xml.c.
14365 ($(BLD)/xml.$(O)): New dependency list.
14367 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14368 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14369 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14370 [!WINDOWSNT]: New macros.
14371 (init_libxml2_functions, libxml2_loaded_p): New functions.
14372 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14373 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14374 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14375 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14377 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14378 Call init_libxml2_functions before calling libxml2 functions.
14379 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14381 * emacs.c: Don't include libxml/parser.h.
14382 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14383 xmlCleanupParser directly.
14385 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14387 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14389 * indent.c (Fvertical_motion): If there is a display string at
14390 point, use it.vpos to compute how many lines to backtrack after
14391 move_it_to point. (Bug#11133)
14393 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14395 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14396 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14397 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14398 macros related to unification of CJK characters. For the details,
14399 see the discussion following the message here:
14400 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14402 2012-04-04 Chong Yidong <cyd@gnu.org>
14404 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14406 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14408 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
14409 instead of alloca. (Bug#11138)
14411 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
14413 * w32menu.c (is_simple_dialog): Properly check lisp types.
14416 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14418 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14419 position we get to after a call to move_it_to fails the
14420 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14421 only if we wind up in a string from display property. (Bug#11063)
14423 * window.c (Fdelete_other_windows_internal): Invalidate the row
14424 and column information about mouse highlight, so that redisplay
14425 restores it after reallocating the glyph matrices. (Bug#7464)
14427 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14428 string comes from a `display' text property, use the buffer
14429 position of that property as if we actually saw that position in
14431 (move_it_by_lines): Remove the assertion that
14432 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14433 violated when there's a before-string at the beginning of a line.
14436 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14438 * xdisp.c (append_space_for_newline): If the default face was
14439 remapped, use the remapped face for the appended newline.
14440 (extend_face_to_end_of_line): Use the remapped default face for
14441 extending the face to the end of the line.
14442 (display_line): Call extend_face_to_end_of_line when the default
14443 face was remapped. (Bug#11068)
14445 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14447 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14449 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>

14465 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14466 (command_loop_1): Use it; inhibit selection update for
14467 handle-select-window too (Bug#8996).

14471 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14473 2012-03-25 Kenichi Handa <handa@m17n.org>
14475 * dispextern.h (struct glyph): Change the bit length of
14476 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14478 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14480 * s/ms-w32.h (tzname): Include time.h before redirecting to
14481 _tzname. Fixes the MSVC build. (Bug#9960)

14485 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14488 * xterm.c (XTread_socket): Only modify handling_signal if
14489 !SYNC_INPUT. (Bug#11080)
14491 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14493 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14494 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14495 when fetching a multibyte character consumes more bytes than
14496 CHAR_BYTES returns, due to unification of CJK characters in
14497 string_char. (Bug#11073)
14499 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14501 * process.c (wait_reading_process_output): Handle pty disconnect
14502 by refraining from sending oneself a SIGCHLD (bug#10933).
14504 2012-03-22 Chong Yidong <cyd@gnu.org>
14506 * dispextern.h (struct it): New member string_from_prefix_prop_p.
14508 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
14509 Mark string as coming from a prefix property.
14510 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14511 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14513 2012-03-21 Chong Yidong <cyd@gnu.org>
14515 * xfaces.c (Vface_remapping_alist): Doc fix.
14517 2012-03-20 Eli Zaretskii <eliz@gnu.org>

14531 it fit in a valid range (Bug#11003).
14533 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14535 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14536 that is not from display property, accept the row as a "cursor
14537 row" if one of the string's character has a non-nil `cursor'
14538 property. Fixes cursor positioning when there are newlines in
14539 overlay strings, e.g. in icomplete.el. (Bug#11035)
14541 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14543 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14545 2012-03-12 Chong Yidong <cyd@gnu.org>
14547 * eval.c (inhibit_lisp_code): Rename from
14548 inhibit_window_configuration_change_hook; move from window.c.
14550 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14551 * window.c (run_window_configuration_change_hook)
14552 (syms_of_window): Callers changed.
14554 2012-03-11 Chong Yidong <cyd@gnu.org>
14556 * keymap.c (Fkey_description): Doc fix (Bug#9700).

14560 2012-03-10 Chong Yidong <cyd@gnu.org>
14562 * frame.c (other_visible_frames): Don't assume the selected frame
14563 is visible (Bug#10955).
14565 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
14567 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14569 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14571 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14572 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14575 2012-03-03 Glenn Morris <rgm@gnu.org>
14577 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14579 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14581 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14582 position past the first glyph_row that ends at ZV. (Bug#10902)
14583 (redisplay_window, next_element_from_string): Fix typos in
14585 (redisplay_window): Pass to move_it_vertically the margin in
14586 pixels, not in screen lines.
14588 2012-03-02 Glenn Morris <rgm@gnu.org>
14590 * buffer.c (buffer-list-update-hook): Doc fix.
14592 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14594 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14595 push_it before setting up the iterator for the first overlay
14596 string, even if we have an empty string loaded.
14597 (next_overlay_string): If there's an empty string on the iterator
14598 stack, pop the stack. (Bug#10903)
14600 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14602 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14603 Suggested by Stefan Monnier in
14604 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14605 * alloc.c (widen_to_Lisp_Object): New static function.
14606 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14607 and widening them to Lisp_Objects. This would work even if
14608 USE_LSB_TAG is defined and wide integers are used, which might
14609 happen in a future version of Emacs.
14611 2012-02-25 Chong Yidong <cyd@gnu.org>
14613 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14616 * xselect.c (Fx_selection_exists_p): Doc fix.

14618 before saving to clipboard manager.
14620 2012-02-24 Chong Yidong <cyd@gnu.org>
14622 * keyboard.c (process_special_events): Handle all X selection
14623 requests in kbd_buffer, not just the next one (Bug#8869).
14625 2012-02-23 Chong Yidong <cyd@gnu.org>
14627 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14628 call when setting menu-bar-lines and tool-bar-lines parameters.
14629 (unwind_create_frame_1): New helper function.
14631 * window.c (inhibit_window_configuration_change_hook): New var.
14632 (run_window_configuration_change_hook): Obey it.
14633 (syms_of_window): Initialize it.
14635 2012-02-22 Chong Yidong <cyd@gnu.org>
14637 * xterm.c (x_draw_image_relief): Add missing type check for
14638 Vtool_bar_button_margin (Bug#10743).

14642 * fileio.c (Vfile_name_handler_alist): Doc fix.
14644 * buffer.c (Fget_file_buffer): Protect against invalid file
14645 handler return value.
14647 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
14649 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
14650 when computing $valmask.
14652 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14653 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14654 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14655 It's useless in that case, and it can cause problems on hosts
14656 that allocate halves of EMACS_INT values separately.
14657 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14658 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14659 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14660 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14661 it avoids undefined behavior on hosts where shifting right by more
14662 than the word width has undefined behavior.
14664 2012-02-19 Chong Yidong <cyd@gnu.org>
14666 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14667 (Funhandled_file_name_directory, Ffile_name_as_directory)
14668 (Fdirectory_file_name, Fexpand_file_name)
14669 (Fsubstitute_in_file_name): Protect against invalid file handler
14670 return values (Bug#10845).
14672 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14674 * .gdbinit (pitx): Fix incorrect references to fields of the

14684 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14686 2012-02-15 Chong Yidong <cyd@gnu.org>
14688 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14689 marked as special. Also, starting docstrings with * is obsolete.

14702 * keymap.c (Fsingle_key_description): Handle char ranges.
14704 2012-02-12 Chong Yidong <cyd@gnu.org>
14706 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14707 as that creates a dangerous corner case.
14709 * window.c (Fdelete_window_internal): Invalidate the mouse
14710 highlight (Bug#9904).
14712 2012-02-12 Glenn Morris <rgm@gnu.org>

14717 * nsselect.m (Fx_own_selection_internal)
14718 (Fx_disown_selection_internal, Fx_selection_exists_p)
14719 (Fx_selection_owner_p, Fx_get_selection_internal):
14720 Sync docs and argument specs with the xselect.c versions.
14722 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>

14742 2012-02-07 Chong Yidong <cyd@gnu.org>
14744 * buffer.c (Fbuffer_local_variables)
14745 (buffer_lisp_local_variables): Handle unbound vars correctly;
14746 don't let Qunbound leak into Lisp.
14748 2012-02-07 Glenn Morris <rgm@gnu.org>
14750 * image.c (Fimagemagick_types): Doc fix.
14752 * image.c (imagemagick-render-type): Change it from a lisp object
14753 to an integer. Move the doc here from the lisp manual.

14770 2012-02-04 Eli Zaretskii <eliz@gnu.org>
14772 * w32.c (get_emacs_configuration_options):
14773 Include --enable-checking, if specified, in the return value.

14777 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
14778 after rounding frame sizes. (Bug#9723)

14783 before BEGV. (Bug#10696)
14785 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
14787 Handle overflow when computing char display width (Bug#9496).
14788 * character.c (char_width): Return EMACS_INT, not int.
14789 (char_width, c_string_width): Check for overflow when
14790 computing the width; this is possible now that individual
14791 characters can have unbounded width. Problem introduced
14792 by merge from Emacs 23 on 2012-01-19.

14812 0, do not call append_composite_glyph.
14814 2012-02-02 Kenichi Handa <handa@m17n.org>
14816 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
14818 (x_produce_glyphs): If the component of a composition is a null
14819 string, set it->pixel_width to 1 to avoid zero-width glyph.

14823 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14824 first 2 arguments are identical. This makes inserting large
14825 output from a subprocess an order of magnitude faster on
14826 MS-Windows, where all sbrk'ed memory is always contiguous.
14828 2012-01-31 Glenn Morris <rgm@gnu.org>
14830 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

14926 DISP_STRING, and accept any glyph in a row whose object is that
14927 string as eligible for mouse highlight. Fixes mouse highlight of
14928 display strings from overlays. (Bug#10464)
14930 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
14932 emacs: fix an auto-save permissions race condition (Bug#10400)

14934 (Fmake_directory_internal): Use it.

15279 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
15280 verifies glyph row's hash code--we have just reallocated the
15281 glyphs, so their contents can be complete garbage. (Bug#10164)

15445 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15446 is set, removing the need for VIRT_ADDRESS_VARIES.
15447 (PURE_P): Use a more-efficient implementation that needs just one
15448 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the

15450 to 4 (xorl, subq, cmpq, setbe).
15451 * alloc.c (pure): Always extern now, since that's the

15454 consistency with the new puresize.h.
15455 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
15456 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

15462 (erase_phys_cursor, update_window_cursor, show_mouse_face)
15463 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
15464 behave as if the cursor position were at the window margin.
15466 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15467 and the cursor position is out of bounds, behave as if the cursor
15468 position were at the window margin. (Bug#10075)
15470 2011-11-18 Chong Yidong <cyd@gnu.org>
15472 * window.c (Fwindow_combination_limit): Make first argument

15493 * xdisp.c (row_hash): New function, body extracted from
15494 compute_line_metrics.
15495 (compute_line_metrics): Call row_hash, instead of computing the
15498 * dispnew.c (verify_row_hash): Call row_hash for computing the
15499 hash code of a row, instead of duplicating code from xdisp.c.
15501 * dispextern.h (row_hash): Add prototype.
15503 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
15505 * frame.c (delete_frame): Don't delete the terminal when the last

15527 * window.c (Fwindow_nest): Rename to Fwindow_combination_limit.
15528 (Fset_window_nest): Rename to Fset_window_combination_limit.
15529 (Vwindow_nest): Rename to Vwindow_combination_limit.
15530 (recombine_windows, make_parent_window, make_window)
15531 (Fsplit_window_internal, saved_window)
15532 (Fset_window_configuration, save_window_save): Rename all
15533 occurrences of window_nest to window_combination_limit.
15535 2011-11-15 Juanma Barranquero <lekktu@gmail.com>

15539 2011-11-14 Eli Zaretskii <eliz@gnu.org>
15541 * xdisp.c (display_line): Move the call to
15542 highlight_trailing_whitespace before the call to

15993 terminal (Bug#6649).
15995 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15997 * dispextern.h (struct bidi_it): New member next_en_type.
15999 * bidi.c (bidi_line_init): Initialize the next_en_type member.
16000 (bidi_resolve_explicit_1): When next_en_pos is valid for the
16001 current character, check also for next_en_type being WEAK_EN.
16002 (bidi_resolve_weak): Don't enter the expensive loop if the current
16003 position is before next_en_pos. Record the bidi type of the first
16004 non-ET, non-BN character we find, in addition to its position.
16005 (bidi_level_of_next_char): Invalidate next_en_type when
16006 next_en_pos is over-stepped.
16008 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
16010 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
16011 * editfns.c: Rewrite current-time-zone so that it invokes
16012 the equivalent of (format-time-string "%Z") to get the time zone name.
16013 This fixes a bug when the time zone name contains characters that
16014 need converting from the system time locale to Emacs internal format.
16015 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
16016 that patch fixed format-time-string to do the conversion, but
16017 I forgot to fix current-time-zone.
16018 (format_time_string): New function, containing most of
16019 what Fformat_time_string used to contain.
16020 (Fformat_time_string): Rewrite in terms of format_time_string.
16021 This doesn't change this function's behavior.
16022 (current-time-zone): Rewrite to use format_time_string.
16023 This fixes the bug reported by Michael Schierl in
16024 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
16025 Jason Rumney's 2007-06-07 change worked around this bug, but
16027 * systime.h (tzname, timezone): Remove no-longer-used declarations.
16029 2011-10-19 Eli Zaretskii <eliz@gnu.org>
16031 * xdisp.c (start_display): If the character at POS is displayed
16032 via a display vector, reset IT->current.dpvec_index to zero.
16033 (try_window_reusing_current_matrix): If a line ends in a display
16034 vector or the next line starts in a display vector, continue
16035 redrawing the window even though the character position of
16036 start_row was reached.
16039 2011-10-18 Chong Yidong <cyd@gnu.org>
16041 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
16042 with nobreak-char-display too.
16044 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16046 Fix part 3 of bug#9771.
16047 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16048 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16049 non-neutral characters if the current character is a paragraph
16050 separator (a.k.a. Newline). This avoids running the same
16051 expensive loop twice, once when we consume the preceding newline
16052 and the other time when the line actually needs to be displayed.
16053 Avoid the loop when we see neutrals on the base embedding level
16054 following a character whose directionality is the same as the
16055 paragraph's. This avoids running the expensive loop when a line
16056 ends in a long sequence of neutrals, like control characters.
16057 Add assertion against STRONG_AL type. Slightly rearrange code
16058 that determines the type of a neutral given the first non-neutral
16060 (bidi_level_of_next_char): Set next_en_pos to zero when
16061 invalidating its info.
16063 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16065 * xdisp.c (push_display_prop): Determine whether to record string
16066 or buffer position by IT->string, not by IT->method. Allow
16067 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16068 (move_it_vertically_backward): Don't look for character position
16069 immediately after the newline when in a continuation line.
16072 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16074 * window.c (coordinates_in_window): Rewrite and delabelize
16075 vertical border check. (Bug#5357) (Bug#9618)
16077 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16079 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16080 errors in XSetWindowBorder (bug#9310).
16082 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16084 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16085 avoid crash when xmalloc overrun checking is enabled.
16087 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16089 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16090 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16091 cursor motion with <left> and <right> arrow keys.
16093 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16094 some callers set that themselves.
16096 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16098 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16099 display string and the previous row comes from the same string and
16100 is empty. (Bug#9739) (Bug#9738)
16102 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16104 * doc.c (get_doc_string): Encode file name (bug#9735).
16106 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16108 * bidi.c (bidi_level_of_next_char):
16109 * xdisp.c (get_visually_first_element): Remove old incorrect
16110 comments regarding the Unicode Line Separator character.
16112 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16114 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16116 * alloc.c (Fgc_status): Do not access beyond zombies array
16117 boundary if nzombies > MAX_ZOMBIES.
16118 * alloc.c (dump_zombies): Add missing format specifier.
16120 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16122 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16123 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16125 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16126 Some packages use them to denote characters with modifiers.
16128 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16130 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16131 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16132 matching a pp-number. Rename parameter var to var1.
16134 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16136 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16138 2011-10-08 Glenn Morris <rgm@gnu.org>
16140 * callint.c (Fcall_interactively): Give a more explicit error for the
16141 'c' case with a non-character input. (Bug#8479)
16143 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16145 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16147 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16148 lines that are hscrolled on the left.
16150 * dispnew.c (buffer_posn_from_coords): Account for a possible
16151 presence of header-line. (Bug#4426)
16153 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16155 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16156 Don't advertise functionality which we discourage or doesn't work.
16158 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16160 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16161 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16162 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16163 this makes Emacs dump core during garbage collection on rare
16164 occasions. sizeof is obviously inferior to offsetof here, so
16165 stick with offsetof.
16166 (GC_POINTER_ALIGNMENT): New macro.
16167 (mark_memory): Omit 3rd (offset) arg; caller changed.
16168 Don't assume EMACS_INT alignment is the same as pointer alignment.
16170 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16172 * keyboard.c (read_key_sequence_remapped): New var.
16173 (read_key_sequence): Compute remapping in the right buffer.
16174 (command_loop_1): Use read_key_sequence's remapping directly.
16176 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16178 * dired.c (file_name_completion): Don't expand file name.
16179 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16180 before checking file name handler.
16182 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16183 they've been requested explicitly (bug#9591).
16185 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16187 * keymap.c (Fsingle_key_description): Use make_specified_string
16188 instead of build_string to build string from push_key_description.
16191 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16193 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16194 This fixes a Y2038 bug on 64-bit hosts.
16195 * buffer.c (reset_buffer):
16196 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16197 (Fclear_buffer_auto_save_failure):
16198 Use 0, not -1, to represent an unset failure time, since time_t
16199 might not be signed.
16201 Remove dependency on glibc malloc internals.
16202 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16203 Move back here from lisp.h, but with their new implementations.
16204 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16205 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16206 * charset.c (charset_table_init): New static var.
16207 (syms_of_charset): Use it instead of xmalloc. This removes a
16208 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16209 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16210 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16211 Move back to alloc.c.
16212 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16213 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16215 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16217 * nsterm.m (windowDidResize): Call x_set_window_size only when
16218 ns_in_resize is true. Otherwise set pixelwidth/height and
16219 call change_frame_size (Bug#9628).
16221 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16223 Port --enable-checking=all to Fedora 14 x86-64.
16224 * charset.c (syms_of_charset): Also account for glibc malloc's
16225 internal overhead when calculating the initial malloc maximum.
16227 Port --enable-checking=all to Fedora 14 x86.
16228 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16230 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16231 (overrun_check_realloc, overrun_check_free):
16232 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16233 That way, xmalloc returns a properly-aligned pointer even if
16234 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16235 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16236 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16237 into account when calculating the initial malloc maximum.
16238 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16239 Move here from alloc.c, so that charset.c can use it too.
16240 Properly align; the old code wasn't right for common 32-bit hosts
16241 when configured with --enable-checking=all.
16242 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16243 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16245 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16247 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16250 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16252 * xdisp.c (compute_display_string_end): If there's no display
16253 string at CHARPOS, return -1.
16255 * bidi.c (bidi_fetch_char): When compute_display_string_end
16256 returns a negative value, treat the character as a normal
16257 character not covered by a display string. (Bug#9624)
16259 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16261 * lread.c (Fread_from_string): Fix typo in docstring.
16263 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16265 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16266 newline, reseat the iterator instead of bidi-iterating there one
16267 character at a time. (Bug#9610)
16268 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16269 TO_CHARPOS if the bidi iterator is at base embedding level.
16271 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16273 * lread.c (readevalloop): Use correct code for NBSP.
16274 (read1): Likewise. (Bug#9608)
16276 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16278 * dbusbind.c (Fdbus_register_signal): When service is not
16279 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16281 2011-09-25 Glenn Morris <rgm@gnu.org>
16283 * buffer.c (truncate-lines): Doc fix.
16285 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16287 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16288 (Fset_window_next_buffers): Doc fix.
16290 2011-09-24 Glenn Morris <rgm@gnu.org>
16292 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16294 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16296 Fix minor problems found by static checking.
16297 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16298 * indent.c (Fvertical_motion): Fix == vs = typo.
16300 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16302 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16303 Default value is now t. Doc fix.
16305 * indent.c (Fvertical_motion): Compute and apply the overshoot
16306 logic when moving up, not only when moving down. Fix the
16307 confusing name and values of the it_overshoot_expected variable;
16308 logic changes accordingly. (Bug#9254) (Bug#9549)
16310 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16311 CHARPOS is covered by a display string which includes newlines.
16312 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16313 is covered by a display string with embedded newlines.
16315 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16317 * dbusbind.c (Fdbus_register_signal): Add match rule to
16318 Vdbus_registered_objects_table. (Bug#9581)
16319 (Fdbus_register_method, Vdbus_registered_objects_table):
16322 2011-09-24 Jim Meyering <meyering@redhat.com>
16324 do not ignore write error for any output size
16325 The previous change was incomplete.
16326 While it makes emacs --batch detect the vast majority of stdout
16327 write failures, errors were still ignored whenever the output size is
16328 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16329 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16330 && echo FAIL: ignored write error
16331 FAIL: ignored write error
16332 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16333 && echo FAIL: ignored write error
16334 FAIL: ignored write error
16335 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16337 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16339 * emacs.c (Fkill_emacs): In noninteractive mode exit
16340 non-successfully if a write error occurred on stdout. (Bug#9574)
16342 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16344 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16347 * dispextern.h (struct it): Update the comment documenting what
16350 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16352 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16353 a display string, extend search for cursor position to end of row.
16354 (find_row_edges): If the row ends in a newline from a display
16355 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16356 Handle the case of a display string with multiple newlines.
16357 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16358 non-empty line. Fixes confusing cursor motion with arrow keys at
16359 the beginning of a line that starts with whitespace.
16361 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16363 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16366 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16368 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16369 boolean (Bug#9154).
16371 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16373 * xdisp.c (display_line): Record maximum and minimum buffer
16374 positions even if no glyphs were produced (e.g., by a zero-width
16375 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16376 buffer positions that will be removed from the glyph row because
16378 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16379 column is beyond frame width: don't subtract 1 "pixel" when
16380 computing width of the stretch.
16381 (reseat_at_next_visible_line_start): Undo the change made on
16382 2011-09-17 that saved paragraph information and restored it after
16383 the call to `reseat'. (Bug#9545)
16385 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16387 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16388 and turn window cursor on if cleared (Bug#9415).
16390 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16392 * search.c (boyer_moore): Take unibyte characters from pattern
16393 literally. (Bug#9458)
16395 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16397 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16399 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16401 Fix minor problem found by static checking.
16402 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16403 initialized, to pacify gcc -Wuninitialized.
16405 * fileio.c: Report proper errno when syscall falls.
16406 (Finsert_file_contents): Save and restore errno,
16407 so that report_file_error outputs the correct diagnostic.
16408 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16410 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16412 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16414 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16416 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16417 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16419 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16421 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16422 about the current paragraph and restore it after the call to reseat.
16424 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16425 (bidi_find_paragraph_start): Search back for paragraph beginning
16426 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16427 (bidi_move_to_visually_next): Only trigger paragraph-related
16428 computations when the last character is a newline or at EOB, not
16429 just any NEUTRAL_B. (Bug#9470)
16431 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16432 truncated lines if point is covered by a display string. (Bug#9524)
16434 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16436 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16437 (cons_to_x_long): New function.
16438 (lisp_data_to_selection_data): Use it. Correct the test for
16439 short-versus-long data; it was negated. Break out of vector
16440 loop, for efficiency, when a long datum is discovered.
16442 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16444 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16446 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16448 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16449 GCC PR/17406) by declaring this function with external scope.
16451 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16453 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16454 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16456 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16458 * editfns.c (Fformat): Correctly handle text properties on "%%".
16460 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16462 * xterm.c (x_draw_composite_glyph_string_foreground):
16463 * w32term.c (x_draw_composite_glyph_string_foreground):
16464 * term.c (encode_terminal_code):
16465 * composite.c (composition_update_it, get_composition_id):
16466 * xdisp.c (get_next_display_element)
16467 (fill_composite_glyph_string): Add comments about special meaning
16468 of TAB characters in a composition.
16470 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16472 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16473 This occurs when processing a multibyte format.
16474 Problem reported by Wolfgang Jenker.
16476 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16478 * xdisp.c (try_cursor_movement): Only check for exact match if
16479 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16481 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16483 Remove unused external symbols.
16484 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16485 * xdisp.c (calc_pixel_width_or_height): Now static.
16486 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16487 * indent.c (check_display_width):
16488 * w32term.c: Fix comment to match code.
16489 * xterm.c, xterm.h (x_catching_errors): Remove.
16491 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16493 * xselect.c: Use signed conversions more consistently (Bug#9498).
16494 (selection_data_to_lisp_data): Assume incoming selection data are
16495 signed integers, not unsigned. This is to be consistent with
16496 outgoing selection data, which was modified to use signed integers
16497 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16498 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16499 expects long, not unsigned long.
16501 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16503 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16504 computation of loop end. Reported by Johan Bockgård
16507 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16509 * frame.c (Fother_visible_frames_p): Function deleted.
16511 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16513 * indent.c (compute_motion): Process display vector front to back
16514 rather than the other way around. (Bug#2496)
16516 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16518 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16520 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16522 * minibuf.c (Fread_from_minibuffer): Doc fix.
16524 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16526 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16527 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16529 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16531 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16532 value for non-existent files.
16534 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16536 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16537 set its "size" to -1. This will set the modtime_size field of
16538 the corresponding buffer to -1, which is what
16539 verify-visited-file-modtime expects for files that do not exist.
16542 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16544 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16546 * lisp.h: ... from here. push_key_description is no longer
16547 defined in keyboard.c, so its declaration should not be in
16548 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16549 logically belongs with push_key_description.
16551 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16553 * buffer.h: Include <sys/types.h> instead of <time.h>.
16554 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16555 Problem reported by Herbert J. Skuhra.
16557 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16559 * xml.c (parse_region): Make the parsing work for
16560 non-comment-starting XML files again (bug#9144).
16562 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16564 * image.c (gif_load): Fix calculation of bottom and right corner.
16567 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16569 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16570 redisplay in small windows.
16572 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16574 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16576 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16578 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16579 Operate on live windows only.
16581 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16583 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16585 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16587 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16588 only under bidi iteration.
16590 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16592 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16594 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16596 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16597 Without this fix, the command to link temacs failed due to an
16598 undefined symbol __builtin_isnan. This is because
16599 /usr/include/iso/math_c99.h #defines isnan(x) to
16600 __builtin_isnan(x), but the bundled gcc, which identifies itself
16601 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16603 * floatfns.c (isnan): #undef, and then #define to a clone of
16605 (Fisnan): Always define, since it's always available now.
16606 (syms_of_floatfns): Always define isnan at the Lisp level.
16608 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16610 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16612 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16614 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16615 The previous code assumed that file offsets (off_t values) fit in
16616 EMACS_INT variables, which is not true on typical 32-bit hosts.
16617 The code messed up by falsely reporting buffer overflow in cases
16618 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16619 when "big" contains more than 2**29 bytes, even though this
16620 inserts just one byte and does not overflow the buffer.
16621 (Finsert_file_contents): Store file offsets as off_t
16622 values, not as EMACS_INT values. Check for overflow when
16623 converting between EMACS_INT and off_t. When checking for
16624 buffer overflow or for overlap, take the offsets into account.
16625 Don't use EMACS_INT for small values where int suffices.
16626 When checking for overlap, fix a typo: ZV was used where
16627 ZV_BYTE was intended.
16628 (Fwrite_region): Don't assume off_t fits into 'long'.
16629 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16631 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16633 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16635 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16637 sprintf-related integer and memory overflow issues (Bug#9412).
16639 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16640 (esprintf, exprintf, evxprintf): New functions.
16641 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16642 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16643 (modify_event_symbol): Do not assume that the length of
16644 name_alist_or_stem is safe to alloca and fits in int.
16645 (Fexecute_extended_command): Likewise for function name and binding.
16646 (Frecursion_depth): Wrap around reliably on integer overflow.
16647 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16648 since some callers pass EMACS_INT values.
16649 (Fsingle_key_description): Don't crash if symbol name contains more
16650 than MAX_ALLOCA bytes.
16651 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16652 (get_minibuffer): Arg is now EMACS_INT, not int.
16653 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16654 (esprintf, exprintf, evxprintf): New decls.
16655 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16657 * dbusbind.c (signature_cat): New function.
16658 (xd_signature, Fdbus_register_signal):
16659 Do not overrun buffer; instead, report string overflow.
16661 * dispnew.c (add_window_display_history): Don't overrun buffer.
16662 Truncate instead; this is OK since it's just a log.
16664 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16665 even if the time zone offset is outlandishly large.
16666 Don't mishandle offset == INT_MIN.
16668 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16669 when creating daemon; the previous buffer-overflow check was incorrect.
16671 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16672 which has the guts of the old verror function.
16674 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16675 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16677 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16678 (font_unparse_xlfd): Don't blindly alloca long strings.
16679 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16680 fits in int, when using sprintf. Use single snprintf to count
16681 length of string rather than counting it via multiple sprintfs;
16682 that's simpler and more reliable.
16683 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16684 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16685 sprintf, in case result does not fit in int.
16687 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16688 (fontset_from_font): Print it.
16690 * frame.c (tty_frame_count): Now printmax_t, not int.
16691 (make_terminal_frame, set_term_frame_name): Print it.
16692 (x_report_frame_params): In X, window IDs are unsigned long,
16693 not signed long, so print them as unsigned.
16694 (validate_x_resource_name): Check for implausibly long names,
16695 and don't assume name length fits in 'int'.
16696 (x_get_resource_string): Don't blindly alloca invocation name;
16697 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16700 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16701 (xg_check_special_colors, xg_set_geometry):
16702 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16704 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16705 Use esprintf, not sprintf, in case result does not fit in int.
16707 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16708 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16709 it as a large positive number.
16710 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16711 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16713 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16714 in case result does not fit in int.
16716 * print.c (float_to_string): Detect width overflow more reliably.
16717 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16718 buffer overrun. Don't assume list length fits in 'int'. Treat
16719 print length of 0 as 0, not as infinity; to be consistent with other
16720 uses of print length in this function. Don't overflow print length
16721 index. Don't assume hash table size fits in 'long', or that
16722 vectorlike size fits in 'unsigned long'.
16724 * process.c (make_process): Use printmax_t, not int, to format
16725 process-name gensyms.
16727 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16729 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16730 to avoid potential buffer overrun.
16732 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16733 if X resource line is longer than 512 bytes.
16735 * xfns.c (x_window): Make sprintf buffer a bit bigger
16736 to avoid potential buffer overrun.
16738 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16740 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16742 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16744 Integer overflow fixes for scrolling, etc.
16745 Without these, Emacs silently mishandles large integers sometimes.
16746 For example, "C-u 4294967297 M-x recenter" was treated as if
16747 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16749 * xdisp.c (try_window_id): Check Emacs fixnum range before
16750 converting to 'int'.
16752 * window.c (window_scroll_line_based, Frecenter):
16753 Check that an Emacs fixnum is in range before assigning it to 'int'.
16754 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16755 values converted from Emacs fixnums.
16756 (Frecenter): Don't wrap around a line count if it is out of 'int'
16757 range; instead, treat it as an extreme value.
16758 (Fset_window_configuration, compare_window_configurations):
16759 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16761 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16762 that can exceed INT_MAX. Check that EMACS_INT value is in range
16763 before assigning it to the (possibly-narrower) index.
16764 (match_limit): Don't assume that a fixnum can fit in 'int'.
16766 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16769 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16770 (Fvertical_motion): Don't wrap around LINES values that don't fit
16771 in 'int'. Instead, treat them as extreme values. This is good
16772 enough for windows, which can't have more than INT_MAX lines anyway.
16774 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16776 * Require libxml/parser.h to avoid compilation warning.
16778 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16780 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16781 since this reportedly can destroy thread storage.
16783 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16785 * syntax.c (find_defun_start): Update all cache variables if
16786 exiting early (Bug#9401).
16788 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16790 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16792 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16793 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16794 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16796 * term.c (tty_append_glyph): New function.
16797 (produce_stretch_glyph): Static function and its prototype deleted.
16799 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16802 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16804 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16805 when checking :margin (Bug#9390).
16806 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16807 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16808 so that the name doesn't mislead. All uses changed.
16810 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16812 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16815 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16817 * xdisp.c (move_it_to): Don't bail out early when reaching
16818 position beyond to_charpos, if we are scanning backwards.
16819 (move_it_vertically_backward): When DY == 0, make sure we get to
16820 the first character in the line after the newline.
16822 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16824 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16825 (ccl_driver): Do not generate an out-of-range pointer.
16826 (Fccl_execute_on_string): Remove unnecessary check for
16827 integer overflow, noted by Stefan Monnier in
16828 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16829 Remove a FIXME that didn't need fixing.
16830 Simplify the newly-introduced buffer reallocation code.
16832 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16834 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16836 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16838 Integer and memory overflow issues (Bug#9196).
16840 * doc.c (get_doc_string): Rework so that
16841 get_doc_string_buffer_size is the actual buffer size, rather than
16842 being 1 less than the actual buffer size; this makes xpalloc more
16845 * image.c (x_allocate_bitmap_record, cache_image):
16846 * xselect.c (Fx_register_dnd_atom):
16847 Simplify previous changes by using xpalloc.
16849 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16850 since either will do and ptrdiff_t is convenient with xpalloc.
16852 * charset.c (charset_table_size)
16853 (struct charset_sort_data.priority): Now ptrdiff_t.
16854 (charset_compare): Don't overflow if priorities differ greatly.
16855 (Fsort_charsets): Don't assume list length fits in int.
16856 Check for size-calculation overflow when allocating sort data.
16857 (syms_of_charset): Allocate an initial charset table that is
16858 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16860 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16862 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16863 The actual value is always <= INT_MAX, and leaving it unsigned made
16864 overflow checking harder.
16866 * dispextern.h (struct glyph_matrix.rows_allocated)
16867 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16868 with xpalloc. The values are still always <= INT_MAX.
16870 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16872 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16873 (SAFE_NALLOCA): New macro.
16875 * region-cache.c (struct boundary.pos, find_cache_boundary)
16876 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16877 (set_cache_region, invalidate_region_cache)
16878 (revalidate_region_cache, know_region_cache, region_cache_forward)
16879 (region_cache_backward, pp_cache):
16880 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16881 so that ptrdiff_t * can be passed to xpalloc.
16882 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16883 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16884 (pp_cache): Don't assume cache_len fits in int.
16885 * region-cache.h: Adjust extern decls to match.
16887 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16888 EMACS_INT, since either will do, for xpalloc.
16890 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16891 (xnmalloc, xnrealloc, xpalloc): New functions.
16893 * bidi.c (bidi_shelve_header_size): New constant.
16894 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16895 (bidi_cache_ensure_space): Avoid integer overflow when allocating.

16898 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16900 Don't update size of array until after memory allocation succeeds,
16901 because xmalloc/xrealloc may not return.
16902 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16903 now that we have proper integer overflow checking.
16904 (record_overlay_string, overlay_strings): Catch overflows when
16905 calculating size of overlay_str_buf.
16907 * callproc.c (Fcall_process): Check for size overflow when
16908 calculating size of args2.
16909 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16910 Normally we prefer signed values, but sticking with ptrdiff_t would
16911 require adding more-complicated checks.
16913 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16914 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.

16954 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16956 * emacs.c (main): Do not reallocate argv, since there is a null at
16957 the end that can be overwritten, and this way there's no need to
16958 worry about size-calculation overflow.
16959 (sort_args): Check for size-calculation overflow.
16961 * eval.c (init_eval_once, grow_specpdl): Don't update size until

16967 Check for integer overflow.
16968 (x_set_alpha): Do not assume XINT fits in int.
16970 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16971 This is for the members text_lines, text_cols, total_lines, total_cols,
16972 where the system imposes an 'int' limit.
16974 * fringe.c (Fdefine_fringe_bitmap):
16975 Don't update size until alloc works.

16980 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16981 Check for size-calculation overflow.
16982 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16983 do, as we prefer signed integers.

16990 * gtkutil.h: Change prototypes to match the above.
16992 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

17039 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
17040 for command line length. Do not attempt to address one before the
17041 beginning of an array, as that's not portable.

17087 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
17088 (X_LONG_MIN): New macros.
17089 Use them to make the following changes clearer.
17090 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
17091 This change doesn't affect the value now, but it may help remind
17092 future maintainers not to raise the value too much later.
17093 (SELECTION_QUANTUM): Remove, replacing with ...
17094 (selection_quantum): ... new function, which avoids overflow.
17096 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17097 assumption that selection length fits in 'int'.

17114 Don't store size until memory allocation succeeds.
17115 (x_get_window_property): Plug memory leak on memory exhaustion.
17116 Don't double-block input; malloc is safe here. Don't assume 2**34
17117 - 4 fits in unsigned long. Add an xassert to check
17118 XGetWindowProperty overflow. Be more careful about overflow
17119 calculations, and distinguish size from memory overflow better.
17120 (receive_incremental_selection): When tracing, don't assume
17121 unsigned int is less than INT_MAX.
17122 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

17125 in the range -65535 through -1 fit in an X unsigned short.
17126 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17127 result parameters unless successful. Rely on cons_to_unsigned
17128 to report problems with elements; the old code wasn't right anyway.
17129 (x_check_property_data): Check for int overflow; we cannot use
17130 a wider type due to X limits.

17163 * lisp.h (hash_lookup, hash_put):
17164 * minibuf.c (Ftest_completion):
17165 Use ptrdiff_t for hash table indexes, not int (which is too
17166 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17167 32-bit --with-wide-int hosts).
17169 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17170 Add a FIXME comment about memory leaks.

17178 with outlandish widths.
17179 * character.h (sanitize_tab_width): Rename from sanitize_width,
17180 now that we have two such functions. All uses changed.

17199 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17200 (x_send_scroll_bar_event): Likewise. Check that the size does not
17201 exceed limits imposed by XClientMessageEvent, as well as the usual
17202 ptrdiff_t and size_t limits.
17204 * keyboard.c: Overflow, signedness and related fixes.
17205 (make_lispy_movement): Use same integer type in forward decl
17206 that is used in the definition.
17207 (read_key_sequence, keyremap_step):
17208 Change bufsize argument back to int, undoing my 2011-03-30 change.
17209 We prefer signed types, and int is wide enough here.
17210 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17211 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17212 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17213 length, not size_t. Use ptrdiff_t for index, not int.
17214 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17215 possibility of integer overflow.

17243 Prefer int to unsigned where either will do.
17244 (tiff_handler): New function, combining the cores of the
17245 old tiff_error_handler and tiff_warning_handler.
17246 This function is rewritten to use vsnprintf and thereby avoid
17247 stack buffer overflows. It uses only the features of vsnprintf
17248 that are common to both POSIX and native Microsoft.
17249 (tiff_error_handler, tiff_warning_handler): Use it.
17250 (tiff_load, gif_load, imagemagick_load_image):
17251 Don't assume :index value fits in 'int'.

17254 the integer types that MagickCropImage accepts. Don't assume
17255 Vimagemagick_render_type has a nonnegative value. Don't assume

17270 handle_single_display_spec, not just 1 or zero.
17271 (handle_single_display_spec): If the display spec is of the form
17272 `(space ...)', and specifies display in the text area, return 2
17274 (try_cursor_movement): Check for the need to scroll more
17275 accurately, and prefer exact match for point under bidi.
17276 Don't advance `row' beyond the last row of the window.

17294 buffers, return left-to-right.
17295 (set_cursor_from_row): Consider candidate row a win if its glyph
17296 represents a newline and point is on that newline. Fixes cursor
17297 positioning on the newline at EOL of R2L text within L2R
17298 paragraph, and vice versa.
17299 (try_cursor_movement): Check continued rows, in addition to
17300 continuation rows. Fixes unwarranted scroll when point enters a
17301 continued line of R2L text within an L2R paragraph, or vice versa.
17302 (cursor_row_p): Consider the case of point being equal to
17303 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17304 from the end of a short line to the beginning of a continued line
17305 of R2L text within L2R paragraph.
17306 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

17325 extra slot even if the purpose is char-code-property-table.
17327 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17329 * xdisp.c (redisplay_window): When computing centering_position,
17330 account for the height of the header line. (Bug#8874)
17332 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17333 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17334 candidate is selected by the mouse, and that candidate has a
17335 composed character under the mouse.
17337 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17338 coordinates reported by pos-visible-in-window-p for a composed
17339 character in column zero.
17341 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

17349 composed buffer positions.
17351 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17353 * image.c (gif_load): Don't assume that each subimage has the same
17354 dimensions as the base image. Handle disposal method that is
17355 "undefined" by the gif spec (Bug#9335).
17357 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17359 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17365 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17366 from an Org mode buffer to a Speedbar frame.
17368 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17369 a composition, take its buffer position from IT->cmp_it.charpos.
17370 Fixes cursor positioning at the beginning of a line that begins
17371 with a composed character.
17373 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17375 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17376 character bidirectional type, use STRONG_L instead. Fixes crashes
17377 in a buffer produced by `describe-categories'.
17379 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17380 members before the level stack, so they would be saved and
17381 restored when copying iterator state. Fixes incorrect reordering
17382 around TABs covered by display properties.
17384 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17386 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

17391 (internal_condition_case_2, internal_condition_case_n):
17392 Remove unnecessary aborts (Bug#9081).
17394 2011-08-17 Eli Zaretskii <eliz@gnu.org>
17396 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
17397 has no `load' handler, try opening the file locally. (Bug#9311)
17399 2011-08-16 Ken Brown <kbrown@cornell.edu>
17401 * gmalloc.c: Expand comment.
17403 2011-08-16 Eli Zaretskii <eliz@gnu.org>

17417 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
17419 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
17420 in the static heap.
17421 [CYGWIN] (special_realloc): New function.
17422 (_realloc_internal_nolock) [CYGWIN]: Use the new function on

17452 after the pid of the process is set to -1 (Bug#8162).
17454 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17456 * xdisp.c (move_it_in_display_line_to): Don't invoke
17457 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17458 ppos_it. Fixes vertical cursor motion when line beginning is
17459 covered by an image. (Bug#9296)
17461 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17463 * nsterm.h (ns_run_ascript): Declare.
17464 (NSAPP_DATA2_RUNASSCRIPT): Define.
17466 * nsfns.m (as_script, as_result, as_status): New static variables.
17467 (ns_run_ascript): New function.
17468 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17469 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17470 the event loop. Get status from as_status (Bug#7276).
17472 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17473 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17474 the event loop (Bug#7276).
17476 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17478 * gnutls.c (QCgnutls_bootprop_priority)

17480 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
17481 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
17482 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
17483 (QCgnutls_bootprop_verify_hostname_error)

17500 (Fnetwork_interface_list): Allocate in increments of bytes instead
17501 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17502 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17504 (struct ifflag_def): notrailers is smart on OSX.
17505 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17506 Get hardware address with getifaddrs if available.
17508 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17510 * xdisp.c (iterate_out_of_display_property): xassert that
17511 IT->position is set to within IT->object's boundaries. Break from
17512 the loop as soon as EOB is reached; avoids infloops in redisplay
17513 when IT->position is set up wrongly due to some bug.
17514 Set IT->current to match the bidi iterator unconditionally.
17515 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17516 entry. Force push_it to save on the stack the current
17517 buffer/string position, to be restored by pop_it. Fix flags in
17518 the iterator structure wrt the object coming from a display
17519 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17520 properties. (Bug#9284)
17522 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17524 * fontset.c (fontset_get_font_group): Add proper type checks.

17537 no-display-properties-and-no-overlays under bidi display.
17538 Set disp_pos in the bidi iterator to avoid searches for display
17539 properties and overlays.
17541 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17543 * editfns.c (Fset_time_zone_rule): Document relationship with the

17552 restore_point_unwind (Bug#5984).
17554 2011-08-07 Juri Linkov <juri@jurta.org>
17556 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17557 to show the arg `TIME' instead of `TIMEVAL'.
17559 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17561 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17562 display property strides EOL and includes a newline, as in
17563 longlines-mode. (Bug#9254)
17564 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17565 word-wrap under bidirectional display. (Bug#9224)
17567 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17568 is non-zero, even if the data buffer is NULL. Fixes a crash in
17569 vertical-motion with longlines-mode. (Bug#9254)
17571 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17573 * bidi.c <bidi_cache_total_alloc>: Now static.
17574 (bidi_initialize): Initialize bidi_cache_total_alloc.
17576 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17579 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17580 amount allocated this far in `bidi_cache_total_alloc'.
17581 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17582 non-zero, only free the data buffer without restoring the cache
17583 contents. All callers changed.
17585 * dispextern.h (bidi_unshelve_cache): Update prototype.
17587 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17588 (move_it_in_display_line, move_it_to)
17589 (move_it_vertically_backward, move_it_by_lines): Replace the call
17590 to xfree to an equivalent call to bidi_unshelve_cache.
17591 (move_it_in_display_line_to): Fix logic of returning
17592 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17594 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17596 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17597 came from a string character with a `cursor' property. (Bug#9229)
17599 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17601 * Makefile.in (LIB_PTHREAD): New variable.
17602 (LIBES): Add LIB_PTHREAD (Bug#9216).
17604 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17605 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17607 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17609 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17611 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17613 * xterm.c (x_find_topmost_parent): New function.
17614 (x_set_frame_alpha): Find topmost parent window with
17615 x_find_topmost_parent and set the property there also (bug#9181).
17616 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17618 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17620 * callproc.c (Fcall_process): Avoid vfork clobbering

17644 for a display string or property. If found, set DISP_PROP_P
17647 * bidi.c (bidi_fetch_char): Accept an additional argument
17648 DISP_PROP_P, and pass it to compute_display_string_pos.
17649 Only handle text covered by a display string if DISP_PROP_P is returned
17650 non-zero. All callers of bidi_fetch_char changed.
17652 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17654 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17656 2010-12-03 Don March <don@ohspite.net>
17658 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17659 last character M-[char] is translated to ESC [char] (bug#7541).
17661 2011-08-02 Kenichi Handa <handa@m17n.org>
17663 * lisp.h (uniprop_table): Extern it.
17665 * chartab.c (uniprop_table): Make it non-static.
17667 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17669 * xdisp.c (forward_to_next_line_start): Accept additional argument
17670 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17672 (reseat_at_next_visible_line_start): Use the bidi iterator state
17673 returned by forward_to_next_line_start to restore the state of
17674 it->bidi_it after backing up to previous newline. (Bug#9212)
17676 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17678 * regex.c (re_comp): Protoize.
17679 (re_exec): Fix return type.
17680 (regexec): Fix type of `ret'. (Bug#9203)
17682 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17684 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17685 This is needed if max-image-size is a floating-point number.
17687 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17689 * print.c (print_object): Print empty symbol as ##.

17700 contents (Bug#9176).
17701 (EmacsTooltip -init): Remove bezels and add shadows to
17704 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17705 or scroll bar (Bug#8470).
17707 * nsfont.m (nsfont_open): Remove assignment to voffset and

17711 * nsterm.h (nsfont_info): Remove voffset field.
17713 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17715 Implement strike-through and overline on NextStep (Bug#8863).
17717 * nsfont.m (nsfont_open): Use underline position provided by font,
17718 instead of hard-coded value of 2.
17719 (nsfont_draw): Call ns_draw_text_decoration instead.

17734 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17736 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17737 Without this fix, if a signal arrives just after memory fills up,
17738 'malloc' might be invoked reentrantly.
17740 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17741 In other words, assume that every image size is allowed, on non-X
17742 hosts. This assumption is probably wrong, but it lets Emacs compile.
17744 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17746 * regex.c (re_iswctype): Convert return values to boolean.
17748 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17750 * xdisp.c (compute_display_string_pos): Don't use cached display
17751 string position if the buffer had its restriction changed.
17754 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17756 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17758 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17760 Integer signedness and overflow and related fixes. (Bug#9079)
17762 * bidi.c: Integer size and overflow fixes.

17764 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17765 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17766 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17767 (bidi_find_other_level_edge):
17768 Use ptrdiff_t instead of EMACS_INT where either will do.
17769 This works better on 32-bit hosts configured --with-wide-int.
17770 (bidi_cache_ensure_space): Check for size-calculation overflow.
17771 Use % rather than repeated addition, for better worst-case speed.
17772 Don't set bidi_cache_size until after xrealloc returns, because it
17774 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17775 (bidi_cache_ensure_space): Also check that the bidi cache size
17776 does not exceed that of the largest Lisp string or buffer. See Eli
17777 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17779 * alloc.c (__malloc_size_t): Remove.
17780 All uses replaced by size_t. See Andreas Schwab's note
17781 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17783 * image.c: Improve checking for integer overflow.
17784 (check_image_size): Assume that f is nonnull, since
17785 it is always nonnull in practice. This is one less thing to
17786 worry about when checking for integer overflow later.
17787 (x_check_image_size): New function, which checks for integer
17788 overflow issues inside X.
17789 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17790 This removes the need for a memory_full check.
17791 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17792 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17793 (xbm_read_bitmap_data): Change locals back to 'int', since
17794 their values must fit in 'int'.
17795 (xpm_load_image, png_load, tiff_load):
17796 Invoke x_create_x_image_and_pixmap earlier,
17797 to avoid much needless work if the image is too large.
17798 (tiff_load): Treat overly large images as if
17799 x_create_x_image_and_pixmap failed, not as malloc failures.
17800 (gs_load): Use x_check_image_size.
17802 * gtkutil.c: Omit integer casts.
17803 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17804 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17806 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17808 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17809 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17810 would wrongly return t on a 64-bit host.
17812 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17813 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17814 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17815 and therefore cause GCC to emit a bogus diagnostic in some cases.
17817 * image.c: Integer signedness and overflow and related fixes.
17818 This is not an exhaustive set of fixes, but it's time to
17819 record what I've got.
17820 (lookup_pixel_color, check_image_size): Remove redundant decls.
17821 (check_image_size): Don't assume that arbitrary EMACS_INT values
17822 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17823 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17824 (tiff_load, imagemagick_load_image):
17825 Check for overflow in size calculations.
17826 (x_create_x_image_and_pixmap): Remove unnecessary test for
17827 xmalloc returning NULL; that can't happen.
17828 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17829 (xpm_color_bucket): Use better integer hashing function.
17830 (xpm_cache_color): Don't possibly over-allocate memory.
17831 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17832 (gif_memory_source):
17833 Use ptrdiff_t, not int or size_t, to record sizes.
17834 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17835 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17836 either works, as we prefer signed integers.
17837 (tiff_read_from_memory, tiff_write_from_memory):
17838 Return tsize_t, not size_t, since that's what the TIFF API wants.
17839 (tiff_read_from_memory): Don't fail simply because the read would
17840 go past EOF; instead, return a short read.
17841 (tiff_load): Omit no-longer-needed casts.
17842 (Fimagemagick_types): Don't assume size fits into 'int'.
17844 Improve hashing quality when configured --with-wide-int.
17845 * fns.c (hash_string): New function, taken from sxhash_string.
17846 Do not discard information about ASCII character case; this
17847 discarding is no longer needed.
17848 (sxhash-string): Use it. Change sig to match it. Caller changed.
17849 * lisp.h: Declare it.
17850 * lread.c (hash_string): Remove, since we now use fns.c's version.
17851 The fns.c version returns a wider integer if --with-wide-int is
17852 specified, so this should help the quality of the hashing a bit.
17854 * emacs.c: Integer overflow minor fix.
17855 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17856 Define only if GNU_LINUX.
17857 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17859 * dispnew.c: Integer signedness and overflow fixes.
17860 Remove unnecessary forward decls, that were a maintenance hassle.
17861 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17863 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17864 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17865 (prepare_desired_row, line_draw_cost):
17866 Use int, not unsigned, where either works.
17867 (save_current_matrix, restore_current_matrix):
17868 Use ptrdiff_t, not size_t, where either works.
17869 (init_display): Check for overflow more accurately, and without
17870 relying on undefined behavior.
17872 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17873 Remove, replacing with the new symbols in lisp.h. All uses changed.
17874 * fileio.c (make_temp_name):
17875 * filelock.c (lock_file_1, lock_file):
17876 * xdisp.c (message_dolog):
17877 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17878 Use pMd etc. instead.
17879 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17880 replacing the pWIDE etc. symbols removed from editfns.c.
17882 * keyboard.h (num_input_events): Now uintmax_t.
17883 This is (very slightly) less likely to mess up due to wraparound.
17886 * buffer.c: Integer signedness fixes.
17887 (alloc_buffer_text, enlarge_buffer_text):
17888 Use ptrdiff_t rather than size_t when either will do, as we prefer
17891 * alloc.c: Integer signedness and overflow fixes.
17892 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17893 (__malloc_size_t): Default to size_t, not to int.
17894 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17895 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17896 Prefer ptrdiff_t to size_t when either would do, as we prefer
17898 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17899 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17900 Now const. Initialize with values that are in range even if char
17902 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17903 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17904 These functions do the right thing with sizes > 2**32.
17905 (check_depth): Now ptrdiff_t, not int.
17906 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17907 Adjust to new way of storing sizes. Check for size overflow bugs
17909 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17910 slightly wrong anyway, as it missed one instance of
17911 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17912 (refill_memory_reserve): Omit needless cast to size_t.
17913 (mark_object_loop_halt): Mark as externally visible.
17915 * xselect.c: Integer signedness and overflow fixes.
17916 (Fx_register_dnd_atom, x_handle_dnd_message):
17917 Use ptrdiff_t, not size_t, since we prefer signed.
17918 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17919 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17920 x_dnd_atoms_size and x_dnd_atoms_length.
17922 * doprnt.c: Prefer signed to unsigned when either works.
17924 * doprnt.c (doprnt):
17926 * xdisp.c (vmessage):
17927 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17928 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17929 prefer signed arithmetic to avoid comparison confusion.
17930 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17931 but is a bit tricky.
17933 Assume freestanding C89 headers, string.h, stdlib.h.
17934 * data.c, doprnt.c, floatfns.c, print.c:
17935 Include float.h unconditionally.
17936 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17937 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17938 * regex.c: Likewise for stddef.h, string.h.
17939 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17940 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17941 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17942 (STDC_HEADERS): Remove obsolete defines.
17943 * sysdep.c: Include limits.h unconditionally.
17945 Assume support for memcmp, memcpy, memmove, memset.
17946 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17947 * regex.c (memcmp, memcpy):
17948 Remove; we assume C89 now.
17950 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17951 (__malloc_safe_bcopy): Remove; no longer needed.
17953 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17954 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17955 well either way, and we prefer signed to unsigned.
17957 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17959 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17960 closes the connection while we're reading (bug#9182).
17962 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17964 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17965 are specified (Bug#9168).
17967 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17969 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17970 Found by GCC static checking and --with-wide-int on a 32-bit host.
17972 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17974 * xdisp.c (compute_display_string_pos): Fix logic of caching
17975 previous display string position. Initialize cached_prev_pos to
17976 -1. Fixes slow-down at the beginning of a buffer.
17978 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17980 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17981 for attrs[LFACE_FONTSET_INDEX].
17983 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17985 * xml.c (parse_region): Remove unused local
17986 that was recently introduced.
17988 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17990 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17991 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17993 * xdisp.c (move_it_in_display_line_to): Record the best matching
17994 position for TO_CHARPOS while scanning the line, and restore it on
17995 exit if none of the characters scanned was an exact match.
17996 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17997 when exact match is impossible due to invisible text, and the
17998 lines are truncated.
18000 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
18002 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
18005 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18007 Fix a significant slow-down of cursor motion with C-n, C-p,
18008 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
18009 auto-repeat under bidi redisplay in fontified buffers.
18010 * xdisp.c (compute_stop_pos_backwards): New function.
18011 (next_element_from_buffer): Call compute_stop_pos_backwards to
18012 find a suitable prev_stop when we find ourselves before
18014 (reseat): Don't look for prev_stop, as that could mean a very long
18016 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
18017 <cached_disp_overlay_modiff>: Cache for last found display string
18019 (compute_display_string_pos): Return the cached position if asked
18020 about the same buffer in the same area of character positions, and
18021 the buffer wasn't changed since the time the display string
18022 position was cached.
18024 2011-07-22 Eli Zaretskii <eliz@gnu.org>
18026 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
18027 is an integer, which is important for empty lines. (Bug#9149)
18029 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
18031 * frame.c (Fmodify_frame_parameters): In tty case, update the
18032 default face if necessary (Bug#4238).
18034 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
18036 * editfns.c (Fstring_to_char): No need to explain what a character
18037 is in the docstring (Bug#6576).
18039 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18041 * xml.c (parse_region): Make sure we always return a tree.
18043 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18045 * xml.c (parse_region): If a document contains only comments,
18048 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18050 * xml.c (make_dom): Return comments, too.
18052 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18055 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18056 and the surrounding thread.
18057 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18058 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18059 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18061 * s/openbsd.h (BROKEN_SIGIO): Define.
18062 * unexelf.c (unexec) [__OpenBSD__]:
18063 Don't update the .mdebug section of the Alpha COFF symbol table.
18065 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18067 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18070 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18072 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18073 This fixes some race conditions on the permissions of any newly
18076 * alloc.c (valid_pointer_p): Use pipe, not open.
18077 This fixes some permissions issues when debugging.
18079 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18080 If fchown fails to set both uid and gid, try to set just gid,
18081 as that is sometimes allowed. Adjust the file's mode to eliminate
18082 setuid or setgid bits that are inappropriate if fchown fails.
18084 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18086 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18087 to compare Lisp_Objects.
18088 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18089 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18090 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18092 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18094 * lread.c (read_integer): Unread even EOF character.
18095 (read1): Likewise. Properly record start position of symbol.
18097 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18098 symbol character follows.
18100 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18102 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18103 This works around a problem with the previous change to Fcopy_file.
18104 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18105 and without this change, GCC might complain about discarding
18106 fchown's return value.
18108 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18110 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18112 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18114 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18116 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18118 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18119 it's used from the C level.
18121 * process.c: Use the same condition for POLL_FOR_INPUT in both
18122 keyboard.c and process.c (bug#1858).
18124 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18126 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18127 (Fgnutls_boot): Use it.
18129 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18131 * doc.c (Fsubstitute_command_keys): Revert last change.
18133 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18135 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18136 quotes the next character, and doesn't affect other longer
18137 sequences (bug#8935).
18139 * lread.c (syms_of_lread): Clarify that is isn't only
18140 `eval-buffer' and `eval-defun' that's affected by
18141 `lexical-binding' (bug#8460).
18143 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18145 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18146 bidi redisplay when a line includes both an image and is truncated.
18148 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18150 Fix minor problems found by static checking.
18151 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18152 (elsz): Now a signed constant, not a size_t var. We prefer signed
18153 types to unsigned, to avoid integer comparison confusion. Without
18154 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18155 "cannot optimize loop, the loop counter may overflow", a symptom
18157 * indent.c (Fvertical_motion): Mark locals as initialized.
18158 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18160 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18162 * search.c (Fre_search_backward): Mention `case-fold-search' in
18163 all the re_search_* functions (bug#8138).
18165 * keyboard.c (Fopen_dribble_file): Document when the file is
18168 2011-07-14 Eli Zaretskii <eliz@gnu.org>
18170 * bidi.c (bidi_dump_cached_states): Fix format of displaying
18173 Support bidi reordering of display and overlay strings.
18174 * xdisp.c (compute_display_string_pos)
18175 (compute_display_string_end): Accept additional argument STRING.
18176 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
18177 (reseat_to_string): Initialize bidi_it->string.s and
18178 bidi_it->string.schars.
18179 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
18180 NULL (avoids a crash in bidi_paragraph_init).
18181 Initialize itb.string.lstring.
18182 (init_iterator): Call bidi_init_it only of a valid
18183 buffer position was specified. Initialize paragraph_embedding to
18185 (reseat_to_string): Initialize the bidi iterator.
18186 (display_string): If we need to ignore text properties of
18187 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18188 original value of -1 will not work with bidi.)
18189 (compute_display_string_pos): First arg is now struct
18190 `text_pos *'; all callers changed. Support display properties on
18192 (compute_display_string_end): Support display properties on Lisp
18194 (init_iterator, reseat_1, reseat_to_string): Initialize the
18195 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18196 when iterating on a string not from display properties).
18197 (compute_display_string_pos, compute_display_string_end):
18198 Fix calculation of the object to scan. Fixes an error when using
18200 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18201 base_level_stop; instead, set base_level_stop to BEGV.
18202 Fixes crashes in vertical-motion.
18203 (next_element_from_buffer): Improve commentary for when
18204 the iterator is before prev_stop.
18205 (init_iterator): Initialize bidi_p from the default value of
18206 bidi-display-reordering, not from buffer-local value. Use the
18207 buffer-local value only if initializing for buffer iteration.
18208 (handle_invisible_prop): Support invisible properties on strings
18209 that are being bidi-reordered.
18210 (set_iterator_to_next): Support bidi reordering of C strings and
18212 (next_element_from_string): Support bidi reordering of Lisp
18214 (handle_stop_backwards): Support Lisp strings as well.
18215 (display_string): Support display of R2L glyph rows.
18216 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18217 (init_iterator): Don't initialize it->bidi_p for strings
18219 (reseat_to_string): Initialize it->bidi_p for strings here.
18220 (next_element_from_string, next_element_from_c_string)
18221 (next_element_from_buffer): Add xassert's for correspondence
18222 between IT's object being iterated and it->bidi_it.string
18224 (face_before_or_after_it_pos): Support bidi iteration.
18225 (next_element_from_c_string): Handle the case of the first string
18226 character that is not the first one in the visual order.
18227 (get_visually_first_element): New function, refactored from common
18228 parts of next_element_from_buffer, next_element_from_string, and
18229 next_element_from_c_string.
18230 (tool_bar_lines_needed, redisplay_tool_bar)
18231 (display_menu_bar): Force left-to-right direction. Add a FIXME
18232 comment for making that be controlled by a user option.
18233 (push_it, pop_it): Save and restore the state of the
18234 bidi iterator. Save and restore the bidi_p flag.

18680 * alloc.c (mark_buffer):
18681 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
18682 (clone_per_buffer_values): Don't assume that
18683 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
18684 This isn't true in general, and it's particularly not true
18685 if Emacs is configured with --with-wide-int.
18686 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18687 New macros, used in the buffer.c change.

18708 (read_settings, apply_xft_settings): Add comment.
18709 (read_and_apply_settings): Add comment. Call map_tool_bar_style and

18721 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
18723 Random fixes. E.g., (random) never returned negative values.
18724 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18725 subseconds part to the entropy, as that's a bit more random.
18726 Prefer signed to unsigned, since the signedness doesn't matter and
18727 in general we prefer signed. When given a limit, use a
18728 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18729 latter isn't right if USE_2_TAGS_FOR_INTS.
18730 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18731 not 0..VALMASK. Don't discard "excess" bits that random () returns.
18733 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
18735 * textprop.c (text_property_stickiness):
18736 Obey Vtext_property_default_nonsticky.
18737 (syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.

18743 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18744 This is more efficient than Ffile_directory_p and avoids a minor race.
18746 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18748 * buffer.c (Foverlay_put): Say what the return value is
18751 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18752 is a directory before asking whether to use the file name
18754 (barf_or_query_if_file_exists): Make the "File is a directory"
18755 error be more correct.
18757 * fns.c (Frequire): Remove the mention of the .gz files, since
18758 that's installation-specific, but keep the mention of
18759 `get-load-suffixes'.
18761 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
18763 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18769 (syms_of_gnutls): Remove duplicate DEFSYM for
18770 Qgnutls_bootprop_verify_hostname_error, an error for
18771 Qgnutls_bootprop_verify_error (which is no longer used).
18773 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18774 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18775 Also (re)move comments that are misplaced or no longer relevant.
18777 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
18779 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

18807 * fns.c (Frequire): Mention .el.gz files (bug#7314).
18808 (Frequire): Mention get-load-suffixes.

18838 (syms_of_keymap): Defsubr make-composed-keymap.
18839 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

18876 * eval.c (struct backtrace): Simplify and port the data structure.
18877 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18878 signed bit field, as this assumption is not portable and it makes
18879 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18880 "char debug_on_exit : 1" as this is not portable either; instead,
18881 use the portable "unsigned int debug_on_exit : 1". Remove unused
18882 member evalargs. Remove obsolete comments about cc bombing out.
18884 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

19112 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
19113 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
19114 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19116 (debug_method_add): Use va_list and vsprintf rather than relying
19117 on undefined behavior with wrong number of arguments.
19118 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19119 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19120 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19121 since we're not interested in debugging glyphs with old libraries.
19122 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19123 GCC 4.6.0's static checking.
19125 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
19127 Integer overflow and signedness fixes (Bug#8873).
19128 A few related buffer overrun fixes, too.

19132 * dispextern.h (struct face.stipple):
19133 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)

19136 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
19137 (x_create_bitmap_from_xpm_data):
19138 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
19139 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
19141 * xfaces.c (load_pixmap):
19142 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
19143 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
19144 (.bitmaps_last, struct x_output.icon_bitmap):
19145 Use ptrdiff_t, not int, for bitmap indexes.
19146 (x_allocate_bitmap_record): Check for size overflow.
19147 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19149 Use ptrdiff_t, not int, for overlay counts.
19150 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19151 * editfns.c (overlays_around, get_pos_property):
19152 * textprop.c (get_char_property_and_overlay):
19153 * xdisp.c (next_overlay_change, note_mouse_highlight):
19154 * xfaces.c (face_at_buffer_position):
19155 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19156 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19157 (Fnext_overlay_change, Fprevious_overlay_change)
19158 (mouse_face_overlay_overlaps, Foverlays_in):
19159 Use ptrdiff_t, not int, for sizes.
19160 (overlays_at, overlays_in): Check for size-calculation overflow.
19162 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19164 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19165 (x_session_initialize): Do not assume string length fits in int.
19167 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19168 This is unlikely, but can occur if DPI is outlandish.
19170 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19171 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19173 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19174 * xrdb.c (magic_file_p, search_magic_path):
19175 Omit last arg SUFFIX; it was always 0. All callers changed.
19176 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19178 * xfont.c (xfont_match): Avoid need for strlen.
19180 * xfns.c: Don't assume strlen fits in int.
19181 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19183 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19184 not unsigned long, as we prefer signed integers. All callers changed.
19185 Detect integer overflow in repeat count.
19186 (message_dolog): Don't assume print length fits in 39 bytes.
19187 (display_mode_element): Don't assume strlen fits in int.
19189 * termcap.c: Don't assume sizes fit in int and never overflow.
19190 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19191 (gobble_line): Check for size-calculation overflow.
19193 * minibuf.c (Fread_buffer):
19194 * lread.c (intern, intern_c_string):
19195 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19196 Don't assume string length fits in int.
19198 * keyboard.c (parse_tool_bar_item):
19199 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19201 * font.c: Don't assume string length fits in int.
19202 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19203 Use ptrdiff_t, not int.
19204 (font_intern_prop): Don't assume string length fits in int.
19205 Don't assume integer property fits in fixnum.
19206 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19208 * filelock.c: Fix some buffer overrun and integer overflow issues.
19209 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19210 Reformulate so as not to need the command string.
19211 Invoke gzip -cd rather than gunzip, as it's more portable.
19212 (lock_info_type, lock_file_1, lock_file):
19213 Don't assume pid_t and time_t fit in unsigned long.
19214 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19215 (current_lock_owner): Prefer signed type for sizes.
19216 Use memcpy, not strncpy, where memcpy is what is really wanted.
19217 Don't assume (via atoi) that time_t and pid_t fit in int.
19218 Check for time_t and/or pid_t out of range, e.g., via a network share.
19219 Don't alloca where an auto var works fine.
19221 * fileio.c: Fix some integer overflow issues.
19222 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19223 Don't assume string length fits in int.
19224 (directory_file_name): Don't assume string length fits in long.
19225 (make_temp_name): Don't assume pid fits in int, or that its print
19226 length is less than 20.
19228 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19230 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19232 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19234 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19235 We prefer signed integers, even for size calculations.
19237 * emacs.c: Don't assume string length fits in 'int'.
19238 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19239 (main): Don't invoke strlen when not needed.
19241 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19242 (XD_DEBUG_MESSAGE): Don't waste a byte.
19244 * callproc.c (getenv_internal_1, getenv_internal)
19245 (Fgetenv_internal):
19246 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19248 * lread.c (invalid_syntax): Omit length argument.
19249 All uses changed. This doesn't fix a bug, but it simplifies the
19250 code away from its former Hollerith-constant appearance, and it's
19251 one less 'int' to worry about when looking at integer-overflow issues.
19252 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19254 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19255 This didn't break anything, but it didn't help either.
19256 It's confusing to put a bogus integer in a place where the actual
19257 value does not matter.
19258 (LIST_END_P): Remove unused macro and its bogus comment.
19259 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19261 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19262 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19264 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19265 We prefer signed types, and the value cannot exceed the EMACS_INT
19266 range anyway (because otherwise the length would not be representable).
19267 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19268 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19269 This avoids a GCC warning when WIDE_EMACS_INT.
19271 * indent.c (sane_tab_width): New function.
19272 (current_column, scan_for_column, Findent_to, position_indentation)
19273 (compute_motion): Use it. This is just for clarity.
19274 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19276 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19278 * lisp.h (lint_assume): New macro.
19279 * composite.c (composition_gstring_put_cache):
19280 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19282 * editfns.c, insdel.c:
19283 Omit unnecessary forward decls, to simplify future changes.
19285 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19287 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19289 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19290 Use much-faster test for byte-length change.
19291 Don't assume string byte-length fits in 'int'.
19292 Check that character arg fits in 'int'.
19293 (mapcar1): Declare byte as byte, for clarity.
19295 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19297 * fns.c (concat): Catch string overflow earlier.
19298 Do not rely on integer wraparound.
19300 * dispextern.h (struct it.overlay_strings_charpos)
19301 (struct it.selective): Now EMACS_INT, not int.
19302 * xdisp.c (forward_to_next_line_start)
19303 (back_to_previous_visible_line_start)
19304 (reseat_at_next_visible_line_start, next_element_from_buffer):
19305 Don't arbitrarily truncate the value of 'selective' to int.
19307 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19309 * composite.c: Don't truncate sizes to 'int'.
19310 (composition_gstring_p, composition_reseat_it)
19311 (composition_adjust_point): Use EMACS_INT, not int.
19312 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19313 not EMACS_UINT, for indexes.
19315 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19317 * buffer.c: Include <verify.h>.
19318 (struct sortvec.priority, struct sortstr.priority):
19319 Now EMACS_INT, not int.
19320 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19321 (struct sortstr.size, record_overlay_string)
19322 (struct sortstrlist.size, struct sortlist.used):
19323 Don't truncate size to int.
19324 (record_overlay_string): Check for size-calculation overflow.
19325 (init_buffer_once): Check at compile-time, not run-time.
19327 2011-06-22 Jim Meyering <meyering@redhat.com>
19329 Don't leak an XBM-image-sized buffer
19330 * image.c (xbm_load): Free the image buffer after using it.
19332 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19335 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19336 that Sun C diagnosed.
19337 * fns.c (secure_hash): Fix pointer signedness issue.
19338 * intervals.c (static_offset_intervals): New function.
19339 (offset_intervals): Use it.
19341 2011-06-21 Leo Liu <sdl.web@gmail.com>
19344 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19347 * fns.c (secure_hash): Rename from crypto_hash_function and change
19348 the first arg to accept symbols.
19349 (Fsecure_hash): New primitive.
19350 (syms_of_fns): New symbols.
19352 2011-06-20 Deniz Dogan <deniz@dogan.se>
19354 * process.c (Fset_process_buffer): Clarify return value in
19357 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19359 * dispnew.c (add_window_display_history): Use BVAR.
19361 * xdisp.c (debug_method_add): Use BVAR.
19362 (check_window_end, dump_glyph_matrix, dump_glyph)
19363 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19365 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19368 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19369 check till after the cache is created in init_frame_faces.
19371 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19373 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19375 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19377 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19378 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19379 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19381 Improve buffer-overflow checking (Bug#8873).
19382 * fileio.c (Finsert_file_contents):
19383 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19384 Remove the old (too-loose) buffer overflow checks.
19385 They weren't needed, since make_gap checks for buffer overflow.
19386 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19387 The old code merely checked for Emacs fixnum overflow, and relied
19388 on undefined (wraparound) behavior. The new code avoids undefined
19389 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19391 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19392 Tune. Don't use wider integers than needed. Don't use alloca.
19393 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19395 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19397 * insdel.c, lisp.h (buffer_overflow): New function.
19398 (insert_from_buffer_1, replace_range, replace_range_2):
19399 * insdel.c (make_gap_larger):
19400 * editfns.c (Finsert_char):
19401 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19403 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19405 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19407 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19409 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19410 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19412 * fileio.c: Don't assume EMACS_INT fits in off_t.
19413 (emacs_lseek): New static function.
19414 (Finsert_file_contents, Fwrite_region): Use it.
19415 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19417 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19419 * fns.c: Don't overflow int when computing a list length.
19420 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19421 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19422 truncation on 64-bit hosts. Check for QUIT every
19423 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19424 faster and is responsive enough.
19425 (Flength): Report an error instead of overflowing an integer.
19426 (Fsafe_length): Return a float if the value is not representable
19427 as a fixnum. This shouldn't happen except in contrived situations.
19428 (Fnthcdr, Fsort): Don't assume list length fits in int.
19429 (Fcopy_sequence): Don't assume vector length fits in int.
19431 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19432 (header_size, word_size): New constants.
19433 (allocate_vectorlike): Don't check size overflow here.
19434 (allocate_vector): Check it here instead, since this is the only
19435 caller of allocate_vectorlike that could cause overflow.
19436 Check that the new vector's length is representable as a fixnum.
19438 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19439 The previous code was bogus. For example, next_almost_prime (32)
19440 returned 39, which is undesirable as it is a multiple of 3; and
19441 next_almost_prime (24) returned 25, which is a multiple of 5 so
19442 why was the code bothering to check for multiples of 7?
19444 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19446 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19448 Variadic C functions now count arguments with ptrdiff_t.
19449 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19450 Back then I didn't know that the Emacs coding style prefers signed int.
19451 Also, in the meantime I found a few more instances where arguments
19452 were being counted with int, which may truncate counts on 64-bit
19453 machines, or EMACS_INT, which may be unnecessarily wide.
19454 * lisp.h (struct Lisp_Subr.function.aMANY)
19455 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19456 Arg counts are now ptrdiff_t, not size_t.
19457 All variadic functions and their callers changed accordingly.
19458 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19459 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19460 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19461 * callint.c (Fcall_interactively): Check arg count for overflow,
19462 to avoid potential buffer overrun. Use signed char, not 'int',
19463 for 'varies' array, so that we needn't bother to check its size
19464 calculation for overflow.
19465 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19466 * eval.c (apply_lambda):
19467 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19468 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19469 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19471 * callint.c (Fcall_interactively): Don't use index var as event count.
19473 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19474 * mem-limits.h (SIZE): Remove; no longer used.
19476 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19478 Remove unnecessary casts.
19479 * xterm.c (x_term_init):
19480 * xfns.c (x_set_border_pixel):
19481 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19482 These aren't needed now that we assume ANSI C.
19484 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19485 It's more likely to cause problems (due to unsigned overflow)
19488 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19490 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19492 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19494 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19496 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19498 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19500 GLYPH_CODE_FACE returns EMACS_INT, not int.
19501 * dispextern.h (merge_faces):
19502 * xfaces.c (merge_faces):
19503 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19504 Don't assume EMACS_INT fits in int.
19506 * character.h (CHAR_VALID_P): Remove unused parameter.
19507 * fontset.c, lisp.h, xdisp.c: All uses changed.
19509 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19511 * fns.c (concat): Minor tuning based on overflow analysis.
19512 This doesn't fix any bugs. Use int to hold character, instead
19513 of constantly refetching from Emacs object. Use XFASTINT, not
19514 XINT, for value known to be a character. Don't bother comparing
19515 a single byte to 0400, as it's always less.
19517 * floatfns.c (Fexpt):
19518 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19520 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19523 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19525 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19526 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19527 incorrectly succeed when S was a string, because 4294967386 was
19528 truncated before it was used.
19530 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19531 Otherwise, an out-of-range integer could cause undefined behavior
19534 * composite.c: Use int, not EMACS_INT, for characters.
19535 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19536 EMACS_INT, for values that are known to be in character range.
19537 This doesn't fix any bugs but is the usual style inside Emacs and
19538 may generate better code on 32-bit machines.
19540 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19541 This is for reasons similar to the recent CHAR_STRING fix.
19542 * charset.c (Fencode_char): Check that character arg is actually
19543 a character. Pass an int to ENCODE_CHAR.
19544 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19545 wider than 'int', as a compile-time check to prevent future regressions
19548 * character.c (char_string): Remove unnecessary casts.
19550 Make sure a 64-bit char is never passed to CHAR_STRING.
19551 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19552 by silently ignoring the top 32 bits, allowing some values
19553 that were far too large to be valid characters.
19554 * character.h: Include <verify.h>.
19555 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19556 arguments are no wider than unsigned, as a compile-time check
19557 to prevent future regressions in this area.
19559 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19560 (Fsubst_char_in_region):
19562 * xdisp.c (decode_mode_spec_coding):
19563 Adjust to CHAR_STRING's new requirement.
19564 * editfns.c (Finsert_char, Fsubst_char_in_region):
19565 * fns.c (concat): Check that character args are actually
19566 characters. Without this test, these functions did the wrong
19567 thing with wildly out-of-range values on 64-bit hosts.
19569 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19570 These casts should not be needed on 32-bit hosts, either.
19571 * keyboard.c (read_char):
19572 * lread.c (Fload): Remove casts to unsigned.
19574 * lisp.h (UNSIGNED_CMP): New macro.
19575 This fixes comparison bugs on 64-bit hosts.
19576 (ASCII_CHAR_P): Use it.
19577 * casefiddle.c (casify_object):
19578 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19579 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19580 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19581 * dispextern.h (FACE_FROM_ID):
19582 * keyboard.c (read_char): Use UNSIGNED_CMP.
19584 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19585 not to EMACS_INT, to avoid GCC warning.
19587 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19589 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19590 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19591 isn't needed on 32-bit machines.
19593 * buffer.c (Fgenerate_new_buffer_name):
19594 Use EMACS_INT for count, not int.
19595 (advance_to_char_boundary): Return EMACS_INT, not int.
19597 * data.c (Qcompiled_function): Now static.
19599 * window.c (window_body_lines): Now static.
19601 * image.c (gif_load): Rename local to avoid shadowing.
19603 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19604 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19605 * alloc.c (make_save_value): Integer argument is now of type
19606 ptrdiff_t, not int.
19607 (mark_object): Use ptrdiff_t, not int.
19608 * lisp.h (pD): New macro.
19609 * print.c (print_object): Use it.
19611 * alloc.c: Use EMACS_INT, not int, to count objects.
19612 (total_conses, total_markers, total_symbols, total_vector_size)
19613 (total_free_conses, total_free_markers, total_free_symbols)
19614 (total_free_floats, total_floats, total_free_intervals)
19615 (total_intervals, total_strings, total_free_strings):
19616 Now EMACS_INT, not int. All uses changed.
19617 (Fgarbage_collect): Compute overall total using a double, so that
19618 integer overflow is less likely to be a problem. Check for overflow
19619 when converting back to an integer.
19620 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19621 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19622 These were 'int' variables that could overflow on 64-bit hosts;
19623 they were never used, so remove them instead of repairing them.
19624 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19625 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19626 Previously, this ceilinged at INT_MAX, but that doesn't work on
19628 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19630 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19631 (allocate_vectorlike): Check for ptrdiff_t overflow.
19632 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19633 when a (possibly-narrower) signed value would do just as well.
19634 We prefer using signed arithmetic, to avoid comparison confusion.
19636 * alloc.c: Catch some string size overflows that we were missing.
19637 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19638 for convenience in STRING_BYTES_MAX.
19639 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19640 The definition here is exact; the one in lisp.h was approximate.
19641 (allocate_string_data): Check for string overflow. This catches
19642 some instances we weren't catching before. Also, it catches
19643 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19644 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19645 and ptrdiff_t and EMACS_INT are both 64 bits.
19647 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19648 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19649 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19651 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19653 * alloc.c (Fmake_string): Check for out-of-range init.
19655 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19657 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.

19679 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19681 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

20238 were just reseat()'ed to a new position.
20240 * xdisp.c (set_cursor_from_row): Set start and stop points
20241 according to the row's direction when priming the loop that looks

20244 (display_prop_intangible_p): Reimplement to call
20245 handle_display_spec instead of single_display_spec_intangible_p.

20257 value of a `display' property is a "replacing spec".
20258 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20259 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20260 the display property, but just return a value indicating whether
20261 the display property will replace the characters it covers.
20262 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20263 frame_window_p members of struct bidi_it.

20289 * gnutls.c: Use Emacs's memory allocators.
20290 Without this change, the gnutls library would invoke malloc etc.
20291 directly, which causes problems on non-SYNC_INPUT hosts, and which
20292 runs afoul of improving memory_full behavior. (Bug#8761)
20293 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20294 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20295 xfree instead of the default malloc, realloc, free.
20296 (Fgnutls_boot): No need to check for memory allocation failure,
20297 since xmalloc does that for us.

20326 need to be updated by these changes.
20327 * fns.c (make_hash_table, maybe_resize_hash_table):
20328 Check for integer overflow with large hash tables.
20329 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20330 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20331 (SXHASH_REDUCE): New macro.
20332 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20333 Use it instead of discarding useful hash info with large hash values.
20334 (sxhash_float): New function.
20335 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20336 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20337 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20338 Rewrite to use FIXNUM_BITS, as this simplifies things.
20339 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20340 Adjust signatures to match updated version of code.
20341 (consing_since_gc): Now EMACS_INT, since a single hash table can
20342 use more than INT_MAX bytes.

20391 Make it possible to run ./temacs.
20393 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20394 syms_of_callproc does the same thing. Remove test for

20417 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20418 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20419 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20421 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20423 * image.c: Various fixes to ImageMagick code comments.
20424 (Fimagemagick_types): Doc fix.
20426 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20428 Minor fixes prompted by GCC 4.6.0 warnings.
20430 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20432 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20433 (x_clipboard_manager_save_all): Move extern decl to ...
20434 * xterm.h: ... here, so that it can be checked for consistency.
20436 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20438 * xselect.c (x_clipboard_manager_save_frame)
20439 (x_clipboard_manager_save_all): New functions.
20440 (Fx_clipboard_manager_save): Lisp function deleted.
20442 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20443 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20445 * xterm.h: Update prototype.
20447 2011-05-28 William Xu <william.xwl@gmail.com>
20449 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20450 exiting (Bug#8239).
20452 2011-05-28 Jim Meyering <meyering@redhat.com>
20454 Avoid a sign-extension bug in crypto_hash_function.
20455 * fns.c (to_uchar): Define.
20456 (crypto_hash_function): Use it to convert some newly-signed
20457 variables to unsigned, to avoid sign-extension bugs. For example,
20458 without this change, (md5 "truc") would evaluate to
20459 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20460 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20461 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20463 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20465 Integer overflow fixes.
20467 * dbusbind.c: Serial number integer overflow fixes.
20468 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20469 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20470 to hold a serial number that is too large for a fixnum.
20471 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20472 Check for serial numbers out of range. Decode any serial number
20473 that was so large that it became a float. (Bug#8722)
20475 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20476 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20477 Use XFASTINT rather than XUINT when numbers are nonnegative.
20478 (xd_append_arg, Fdbus_method_return_internal):
20479 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20480 arguments, check that Lisp number is nonnegative, rather than
20481 silently wrapping negative numbers around. (Bug#8722)
20482 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20485 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20487 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20489 ccl: Add integer overflow checks.
20490 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20491 (IN_INT_RANGE): New macros.
20492 (ccl_driver): Use them to check for integer overflow when
20493 decoding a CCL program. Many of the new checks are whether XINT (x)
20494 fits in int; it doesn't always, on 64-bit hosts. The new version
20495 doesn't catch all possible integer overflows, but it's an
20496 improvement. (Bug#8719)
20498 * alloc.c (make_event_array): Use XINT, not XUINT.
20499 There's no need for unsigned here.
20501 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20502 This follows up to the 2011-05-06 change that substituted uintptr_t
20503 for EMACS_INT. This case wasn't caught back then.
20505 Rework Fformat to avoid integer overflow issues.
20506 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20507 now (part of C89). Include <verify.h>.
20508 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20509 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20510 (Fformat): Avoid the prepass trying to compute sizes; it was only
20511 approximate and thus did not catch overflow reliably. Instead, walk
20512 through the format just once, formatting and computing sizes as we go,
20513 checking for integer overflow at every step, and allocating a larger
20514 buffer as needed. Keep track separately whether the format is
20515 multibyte. Keep only the most-recently calculated precision, rather
20516 than them all. Record whether each argument has been converted to
20517 string. Use EMACS_INT, not int, for byte and char and arg counts.
20518 Support field widths and precisions larger than INT_MAX. Avoid
20519 sprintf's undefined behavior with conversion specifications such as %#d
20520 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20521 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20522 formatting out-of-range floating point numbers with int
20523 formats. (Bug#8668)
20525 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20527 * data.c: Avoid integer truncation in expressions involving floats.
20528 * data.c: Include <intprops.h>.
20529 (arith_driver): When there's an integer overflow in an expression
20530 involving floating point, convert the integers to floating point
20531 so that the resulting value does not suffer from catastrophic
20532 integer truncation. For example, on a 64-bit host (* 4
20533 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20534 Do not rely on undefined behavior after integer overflow.
20536 merge count_size_as_multibyte, parse_str_to_multibyte
20537 * character.c, character.h (count_size_as_multibyte):
20538 Rename from parse_str_to_multibyte; all uses changed.
20539 Check for integer overflow.
20540 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20541 since it's now a duplicate of the other. This is more of
20542 a character than a buffer op, so better that it's in character.c.
20543 * fns.c, print.c: Adjust to above changes.
20545 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20547 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20549 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20551 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20552 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20553 (x_clipboard_manager_save): Now static.
20554 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20556 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20557 (crypto_hash_function): Now static.
20558 Fix pointer signedness problems. Avoid unnecessary initializations.
20560 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20562 * termhooks.h (Vselection_alist): Make it terminal-local.
20564 * terminal.c (create_terminal): Initialize it.
20566 * xselect.c: Support for clipboard managers.
20567 (Vselection_alist): Move to termhooks.h as terminal-local var.
20568 (LOCAL_SELECTION): New macro.
20569 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20570 (symbol_to_x_atom): Remove gratuitous arg.
20571 (x_handle_selection_request, lisp_data_to_selection_data)
20572 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20573 (x_own_selection, x_get_local_selection, x_convert_selection):
20574 New arg, specifying work frame. Use terminal-local Vselection_alist.
20575 (some_frame_on_display): Delete unused function.
20576 (Fx_own_selection_internal, Fx_get_selection_internal)
20577 (Fx_disown_selection_internal, Fx_selection_owner_p)
20578 (Fx_selection_exists_p): New optional frame arg.
20579 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20580 (x_handle_selection_clear): Don't treat other terminals with the
20581 same keyboard specially. Use the terminal-local Vselection_alist.
20582 (x_clear_frame_selections): Use Frun_hook_with_args.
20584 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20586 * xterm.h: Add support for those atoms.
20588 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20590 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20591 (converted_selections, conversion_fail_tag): New global variables.
20592 (x_selection_request_lisp_error): Free the above.
20593 (x_get_local_selection): Remove unnecessary code.
20594 (x_reply_selection_request): Args changed; handle arbitrary array
20595 of converted selections stored in converted_selections.
20596 Separate the XChangeProperty and SelectionNotify steps.
20597 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20598 (x_convert_selection): New function.
20599 (x_handle_selection_event): Simplify.
20600 (x_get_foreign_selection): Don't ignore incoming requests while
20601 waiting for an answer; this will fail when we implement
20602 SAVE_TARGETS, and seems unnecessary anyway.
20603 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20604 (Vx_sent_selection_functions): Doc fix.
20606 2011-05-26 Leo Liu <sdl.web@gmail.com>
20608 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20610 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20612 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20614 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20615 for fringe update if it has periodic bitmap.
20616 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20617 and fringe_bitmap_periodic_p.
20619 * fringe.c (get_fringe_bitmap_data): New function.
20620 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20621 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20622 row. Mark glyph row for fringe update if periodicity changed.
20624 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20625 for fringe update unless it has periodic bitmap.
20627 2011-05-25 Kenichi Handa <handa@m17n.org>
20629 * xdisp.c (get_next_display_element): Set correct it->face_id for
20630 a static composition.
20632 2011-05-24 Leo Liu <sdl.web@gmail.com>
20635 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20637 * fns.c (crypto_hash_function, Fsha1): New function.
20638 (Fmd5): Use crypto_hash_function.
20639 (syms_of_fns): Add Ssha1.
20641 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20643 * gnutls.c: Remove unused macros.
20644 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20645 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20646 Remove macros that are defined and never used.
20647 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20649 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20651 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20652 (Fx_get_selection_internal): Minor cleanup.
20653 (Fx_own_selection_internal): Rename arguments for consistency with
20656 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20658 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20660 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20662 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20664 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20666 * dispnew.c (scrolling_window): Don't exclude the case that the
20667 last enabled row in the desired matrix touches the bottom boundary.
20669 2011-05-21 Glenn Morris <rgm@gnu.org>
20671 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20672 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20673 and add some more files.
20675 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20677 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20678 report_file_error introduced by the change from 2011-05-07.
20680 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20682 * systime.h (Time): Define only if emacs is defined.
20683 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20684 where the include path doesn't have X11/X.h by default. See
20685 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20687 2011-05-20 Kenichi Handa <handa@m17n.org>
20689 * composite.c (find_automatic_composition): Fix previous change.
20691 2011-05-20 Glenn Morris <rgm@gnu.org>
20693 * lisp.mk: New file, split from Makefile.in.
20694 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20695 (shortlisp): Remove.
20696 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20698 2011-05-19 Glenn Morris <rgm@gnu.org>
20700 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20701 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20702 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20703 (lisp): Set the order to that of loadup.el.
20704 (shortlisp): Make it a copy of $lisp.
20705 (SOME_MACHINE_LISP): Remove.
20706 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20707 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20709 2011-05-18 Kenichi Handa <handa@m17n.org>
20711 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20712 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20713 (find_automatic_composition): Mostly rewrite for efficiency.
20715 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20717 * makefile.w32-in: Update dependencies.
20719 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20721 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20722 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20724 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20726 Fix some integer overflow issues, such as string length overflow.
20728 * insdel.c (count_size_as_multibyte): Check for string overflow.
20730 * character.c (lisp_string_width): Check for string overflow.
20731 Use EMACS_INT, not int, for string indexes and lengths; in
20732 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20733 the resulting string length overflows an EMACS_INT; instead,
20734 report a string overflow if no precision given. When checking for
20735 precision exhaustion, use a check that cannot possibly have
20736 integer overflow. (Bug#8675)
20737 * character.h (lisp_string_width): Adjust to new signature.
20739 * alloc.c (string_overflow): New function.
20740 (Fmake_string): Use it. This doesn't change behavior, but saves
20741 a few bytes and will simplify future changes.
20742 * character.c (string_escape_byte8): Likewise.
20743 * lisp.h (string_overflow): New decl.
20745 Fixups, following up to the user-interface timestamp change.
20746 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20747 for UI timestamps, instead of unsigned long.
20748 * msdos.c (mouse_get_pos): Likewise.
20749 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20750 * w32gui.h (Time): Define by including "systime.h" rather than by
20751 declaring it ourselves. (Bug#8664)
20753 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20754 * image.c (clear_image_cache): Likewise.
20756 * term.c (term_mouse_position): Don't assume time_t wraparound.
20758 Be more systematic about user-interface timestamps.
20759 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20760 and sometimes 'EMACS_UINT', to represent these timestamps.
20761 This change causes it to use 'Time' uniformly, as that's what X uses.
20762 This makes the code easier to follow, and makes it easier to catch
20763 integer overflow bugs such as Bug#8664.
20764 * frame.c (Fmouse_position, Fmouse_pixel_position):
20765 Use Time, not unsigned long, for user-interface timestamps.
20766 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20767 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20768 * keyboard.h (last_event_timestamp): Likewise.
20769 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20770 * menu.h (xmenu_show): Likewise.
20771 * term.c (term_mouse_position): Likewise.
20772 * termhooks.h (struct input_event.timestamp): Likewise.
20773 (struct terminal.mouse_position_hook): Likewise.
20774 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20775 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20776 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20777 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20778 what it was before.
20779 * menu.h, termhooks.h: Include "systime.h", for Time.
20781 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20782 Don't assume that the difference between two unsigned long values
20783 can fit into an integer. At this point, we know button_down_time
20784 <= event->timestamp, so the difference must be nonnegative, so
20785 there's no need to cast the result if double-click-time is
20786 nonnegative, as it should be; check that it's nonnegative, just in
20787 case. This bug is triggered when events are more than 2**31 ms
20788 apart (about 25 days). (Bug#8664)
20790 * xselect.c (last_event_timestamp): Remove duplicate decl.
20791 (x_own_selection): Remove needless cast to unsigned long.
20793 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20794 that always fit in int. Use a sentinel instead of a counter, to
20795 avoid a temp and to allay GCC's concerns about possible int overflow.
20796 * frame.h (struct frame): Use int for menu_bar_items_used
20797 instead of EMACS_INT, since it always fits in int.
20799 * menu.c (grow_menu_items): Check for int overflow.
20801 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20803 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20804 Before, the code was not consistent. These values cannot exceed
20805 2**31 - 1 so there's no need to make them unsigned.
20806 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20807 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20808 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20810 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20812 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20813 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20814 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20815 presumably because the widths might not match.
20817 * window.c (size_window): Avoid needless test at loop start.
20819 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20821 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20823 2011-05-12 Drew Adams <drew.adams@oracle.com>
20825 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20827 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20829 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20830 `width' to `bar_area_x' and `bar_area_width', respectively.
20831 (x_scroll_run): Take account of fringe background extension.
20833 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20834 Rename local vars `left' and `width' to `bar_area_x' and
20835 `bar_area_width', respectively.
20836 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20837 background extension.
20839 2011-05-10 Jim Meyering <meyering@redhat.com>
20841 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20843 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20845 * image.c (Finit_image_library): Return t for built-in image types,
20846 like pbm and xbm. (Bug#8640)
20848 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20850 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20852 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20854 * w32console.c (Fset_screen_color): Doc fix.
20855 (Fget_screen_color): New function.
20856 (syms_of_ntterm): Defsubr it.
20858 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20859 unlink the temporary file if Fcall_process didn't create it in the
20861 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20862 child process will be redirected to a file specified with `:file'.
20863 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20864 cue to call_process_cleanup not to close that handle.
20866 2011-05-07 Ben Key <bkey76@gmail.com>
20868 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20869 one of two shell specific rules, either bootstrap-temacs-CMD or
20870 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20871 to the previous implementation of the bootstrap-temacs rule.
20872 The bootstrap-temacs-CMD rule is similar to the previous
20873 implementation of the bootstrap-temacs rule except that it
20874 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20877 These changes, along with some changes to nt/configure.bat,
20878 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20879 earlier fix to add support for --cflags and --ldflags options
20880 that include quotes so that it works whether make uses cmd or
20883 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20885 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20886 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20888 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20889 a string. Handle both cases.
20890 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20891 (Fdbus_register_method): Use Qinvalid_function.
20893 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20895 * makefile.w32-in: Update dependencies.
20896 (LISP_H): Add inttypes.h and stdin.h.
20897 (PROCESS_H): Add unistd.h.
20899 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20901 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20902 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20904 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20906 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20908 * term.c (vfatal): Remove stray call to va_end.
20909 It's not needed and the C Standard doesn't allow it here anyway.
20911 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20912 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20914 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20917 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20919 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20921 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20923 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20925 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20927 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20928 * charset.c (Fdefine_charset_internal): Don't initialize
20929 charset.code_space[15]. The value was garbage, on hosts with
20930 32-bit int (Bug#8600).
20932 * lread.c (read_integer): Be more consistent with string-to-number.
20933 Use string_to_number to do the actual conversion; this avoids
20934 rounding errors and fixes some other screwups. Without this fix,
20935 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20936 (digit_to_number): Move earlier, for benefit of read_integer.
20937 Return -1 if the digit is out of range for the base, -2 if it is
20938 not a digit in any supported base. (Bug#8602)
20940 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20942 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20943 to match comment at start of function. This also removes a
20944 GCC warning about overflow in a 32+64-bit port.
20946 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20948 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20949 Reported by Stefan Monnier in
20950 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20951 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20952 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20954 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20955 (EMACS_UINTPTR): Likewise, with uintptr_t.
20957 * lisp.h: Prefer 64-bit EMACS_INT if available.
20958 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20959 on 32-bit hosts that have 64-bit int, so that they can access
20961 However, temporarily disable this change unless the temporary
20962 symbol WIDE_EMACS_INT is defined.
20964 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20966 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20967 This removes an assumption that EMACS_INT and long are the same
20968 width as pointers. The assumption is true for Emacs porting targets
20969 now, but we want to make other targets possible.
20970 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20971 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20972 In the rest of the code, change types of integers that hold casted
20973 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20974 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20975 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20976 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20977 No need to cast type when ORing.
20978 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20979 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20980 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20981 assume EMACS_INT is the same width as char *.
20982 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20983 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20984 Remove no-longer-needed casts.
20985 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20986 (xg_tool_bar_help_callback, xg_make_tool_item):
20987 Use EMACS_INTPTR to hold an integer
20988 that will be cast to void *; this can avoid a GCC warning
20989 if EMACS_INT is not the same width as void *.
20990 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20991 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20992 (current_message_1, set_message_1):
20993 Use a local to convert to proper width without a cast.
20994 * xmenu.c (dialog_selection_callback): Likewise.
20996 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20997 Also, don't assume VALBITS / RAND_BITS is less than 5,
20998 and don't rely on undefined behavior when shifting a 1 left into
21000 * lisp.h (get_random): Change signature to match.
21002 * lread.c (hash_string): Use size_t, not int, for hash computation.
21003 Normally we prefer signed values; but hashing is special, because
21004 it's better to use unsigned division on hash table sizes so that
21005 the remainder is nonnegative. Also, size_t is the natural width
21006 for hashing into memory. The previous code used 'int', which doesn't
21007 retain enough info to hash well into very large tables.
21008 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
21010 * dbusbind.c: Don't possibly lose pointer info when converting.
21011 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
21012 Use XPNTR rather than XHASH, so that the high-order bits of
21013 the pointer aren't lost when converting through void *.
21015 * eval.c (Fautoload): Don't double-shift a pointer.
21017 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
21019 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
21021 * gnutls.c (DEF_GNUTLS_FN):
21022 * image.c (DEF_IMGLIB_FN): Make function pointers static.
21024 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
21026 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
21029 2011-05-05 Eli Zaretskii <eliz@gnu.org>
21031 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
21032 New version that can reserve upto 2GB of heap space.
21034 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
21036 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
21038 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
21040 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
21041 `gnutls_certificate_set_x509_key_file'.
21043 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21045 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21046 Update dependencies.
21048 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21050 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21051 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21052 Remove unused parameter `fildes'.
21053 * process.c (read_process_output, send_process): Don't pass it.
21055 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21057 Fix previous change: the library cache is defined in w32.c.
21058 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21059 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21061 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21063 Implement dynamic loading of GnuTLS on Windows.
21065 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21066 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21067 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21070 * gnutls.c (Qgnutls_dll): Define.
21071 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21072 (gnutls_*): Declare function pointers.
21073 (init_gnutls_functions): New function to initialize function pointers.
21074 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
21075 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21076 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21077 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21078 (emacs_gnutls_write, emacs_gnutls_read)
21079 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21080 (Fgnutls_available_p): New function.
21081 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21082 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21083 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.

21089 (w32_delayed_load): Move to w32.c.
21091 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21093 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21094 (w32_delayed_load): Move from image.c. When loading a library, record
21095 its filename in the :loaded-from property of the library id.
21096 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21097 Initialize and staticpro them.
21098 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21100 * process.c: Include lisp.h before w32.h, not after.
21101 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21102 instead of gnutls_record_check_pending.
21104 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21106 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21108 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21109 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21112 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21114 * xterm.c (x_set_frame_alpha): Do not set property on anything
21115 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21117 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21119 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21121 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21123 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

21137 * sysdep.c (wait_for_termination_1): Make static.
21138 (wait_for_termination, interruptible_wait_for_termination):
21139 Move after wait_for_termination_1.
21141 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21143 * sysdep.c (interruptible_wait_for_termination): New function
21144 which is like wait_for_termination, but allows keyboard
21147 * callproc.c (Fcall_process): Add (:file "file") as an option for
21149 (Fcall_process_region): Ditto.
21151 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21153 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21154 rather than `XVECTOR (FOO)->size'.
21156 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21157 inttypes.h, as a gnulib replacement is used if it not available in
21160 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21162 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21163 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21164 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21166 * coding.c (coding_alloc_by_realloc): Error out if destination
21167 will grow beyond MOST_POSITIVE_FIXNUM.
21168 (decode_coding_emacs_mule): Abort if there isn't enough place in
21169 charbuf for the composition carryover bytes. Reserve an extra
21170 space for up to 2 characters produced in a loop.
21171 (decode_coding_iso_2022): Abort if there isn't enough place in
21172 charbuf for the composition carryover bytes.

21177 aborting when %lld or %lll format is passed.
21178 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21179 %llo or %llx format is passed. (Bug#8545)
21181 * window.c (window_scroll_line_based): Use a marker instead of
21182 simple variables to record original value of point. (Bug#7952)
21184 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21185 produced by %s or %c overflows available buffer space. (Bug#8545)
21187 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21189 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21190 (SIZE_MAX): Move defn after all includes, as they might #define it.
21192 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21194 * w32.c (init_environment): Warn about defaulting HOME to C:\.

21204 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21206 * doprnt.c (doprnt): Don't return value smaller than the buffer
21207 size if the message was truncated. (Bug#8545).
21209 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21211 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)

21214 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21216 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21218 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21220 * makefile.w32-in: Update dependencies.
21222 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21224 Improve `doprnt' and its usage. (Bug#8545)
21225 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21226 `format_end'. Remove support for %l as a conversion specifier.
21227 Don't use xrealloc. Improve diagnostics when the %l size modifier
21228 is used. Update the commentary.
21230 * eval.c (verror): Simplify calculation of size_t.
21232 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21235 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21237 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21240 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21242 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21243 This makes this file independent of the recent pseudovector change.
21245 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21247 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21249 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21250 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21251 Remove unused local.
21252 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21254 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21255 GCC 4.6.0 optimizes based on type-based alias analysis.
21256 For example, if b is of type struct buffer * and v of type struct
21257 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21258 != &v->size, and therefore "v->size = 1; b->size = 2; return
21259 v->size;" must therefore return 1. This assumption is incorrect
21260 for Emacs, since it type-puns struct Lisp_Vector * with many other
21261 types. To fix this problem, this patch adds a new type struct
21262 vectorlike_header that documents the constraints on layout of vectors
21263 and pseudovectors, and helps optimizing compilers not get fooled
21264 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21265 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21266 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21268 (XSETPVECTYPE): Rewrite in terms of new macro.
21269 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21270 This is a bit clearer, and further avoids the possibility of
21271 undesirable aliasing.
21272 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21273 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21274 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21275 since Lisp_Subr is a special case (no "next" field).
21276 (ASIZE): Now uses header.size rather than size.
21277 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21278 to avoid the hassle of writing XVECTOR (foo)->header.size.
21279 (struct vectorlike_header): New type.
21280 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21281 object, to help avoid aliasing.
21282 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21283 (SUBRP): Likewise, since Lisp_Subr is a special case.
21284 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21285 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21286 (struct Lisp_Hash_Table): Combine first two members into a single
21287 struct vectorlike_header member. All uses of "size" and "next" members
21288 changed to be "header.size" and "header.next".
21289 * buffer.h (struct buffer): Likewise.
21290 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21291 * frame.h (struct frame): Likewise.
21292 * process.h (struct Lisp_Process): Likewise.
21293 * termhooks.h (struct terminal): Likewise.
21294 * window.c (struct save_window_data, struct saved_window): Likewise.
21295 * window.h (struct window): Likewise.
21296 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21297 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21298 * buffer.c (init_buffer_once): Likewise.
21299 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21301 * process.c (Fformat_network_address): Use local var for size,
21304 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21306 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21307 * data.c (atof): Remove decl; no longer used or needed.
21308 (digit_to_number): Move to lread.c.
21309 (Fstring_to_number): Use new string_to_number function, to be
21310 consistent with how the Lisp reader treats infinities and NaNs.
21311 Do not assume that floating-point numbers represent EMACS_INT
21312 without losing information; this is not true on most 64-bit hosts.
21313 Avoid double-rounding errors, by insisting on integers when
21314 parsing non-base-10 numbers, as the documentation specifies.
21315 * lisp.h (string_to_number): New decl, replacing ...
21316 (isfloat_string): Remove.
21317 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21318 (read1): Do not accept +. and -. as integers; this
21319 appears to have been a coding error. Similarly, do not accept
21320 strings like +-1e0 as floating point numbers. Do not report
21321 overflow for integer overflows unless the base is not 10 which
21322 means we have no simple and reliable way to continue.
21323 Break out the floating-point parsing into a new
21324 function string_to_number, so that Fstring_to_number parses
21325 floating point numbers consistently with the Lisp reader.
21326 (digit_to_number): Move here from data.c. Make it static inline.
21327 (E_CHAR, EXP_INT): Remove, replacing with ...
21328 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21329 (string_to_number): New function, replacing isfloat_string.
21330 This function checks for valid syntax and produces the resulting
21331 Lisp float number too. Rework it so that string-to-number
21332 no longer mishandles examples like "1.0e+". Use strtoumax,
21333 so that overflow for non-base-10 numbers is reported only when
21334 there's no portable and simple way to convert to floating point.
21336 * textprop.c (set_text_properties_1): Rewrite for clarity,
21337 and to avoid GCC warning about integer overflow.
21339 * intervals.h (struct interval): Use EMACS_INT for members
21340 where EMACS_UINT might cause problems. See
21341 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21342 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21343 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21345 (offset_intervals): Tell GCC not to worry about length overflow
21346 when negating a negative length.
21348 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21349 (overrun_check_free): Likewise.
21351 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21352 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21355 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21356 (gnutls_make_error): Rename local to avoid shadowing.
21357 (gnutls_emacs_global_deinit): ifdef out; not used.
21358 (Fgnutls_boot): Use const for pointer to readonly storage.
21359 Comment out unused local. Fix pointer signedness problems.
21361 * lread.c (openp): Don't stuff size_t into an 'int'.
21362 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21363 about possible signed overflow.
21365 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21366 (GDK_KEY_g): Don't define if already defined.
21367 (xg_prepare_tooltip): Avoid pointer signedness problem.
21368 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21370 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21371 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21373 * xfns.c (Fx_window_property): Simplify a bit,
21374 to make a bit faster and to avoid GCC 4.6.0 warning.
21375 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21377 * fns.c (internal_equal): Don't assume size_t fits in int.
21379 * alloc.c (compact_small_strings): Tighten assertion a little.
21381 Replace pEd with more-general pI, and fix some printf arg casts.
21382 * lisp.h (pI): New macro, generalizing old pEd macro to other
21383 conversion specifiers. For example, use "...%"pI"d..." rather
21384 than "...%"pEd"...".
21385 (pEd): Remove. All uses replaced with similar uses of pI.
21386 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21387 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21388 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21389 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21390 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21391 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21392 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21394 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21395 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21396 * print.c (safe_debug_print, print_object): Likewise.
21397 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21399 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21400 avoiding the 0 flag, which is not portable.
21401 * process.c (Fmake_network_process): Use pI to avoid cast.
21402 * region-cache.c (pp_cache): Likewise.
21403 * xdisp.c (decode_mode_spec): Likewise.
21404 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21405 behavior on 64-bit hosts with printf arg.
21406 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21407 (x_stop_queuing_selection_requests): Likewise.
21408 (x_get_window_property): Don't truncate byte count to an 'int'
21411 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21412 here, since it parses constructs like leading '-' and spaces,
21413 which are not wanted; and it overflows with large numbers.
21414 Instead, simply match F[0-9]+, which is what is wanted anyway.
21416 * alloc.c: Remove unportable assumptions about struct layout.
21417 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21418 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21419 (allocate_vectorlike, make_pure_vector): Use the new macros,
21420 plus offsetof, to remove unportable assumptions about struct layout.
21421 These assumptions hold on all porting targets that I know of, but
21422 they are not guaranteed, they're easy to remove, and removing them
21423 makes further changes easier.
21425 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21426 This doesn't fix a bug but makes the code clearer.
21427 (string_overrun_cookie): Now const. Use initializers that
21428 don't formally overflow signed char, to avoid warnings.
21429 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21430 can cause Emacs to crash when string overrun checking is enabled.
21431 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21432 multiple of sizeof (EMACS_INT); it need not be, if
21433 alignof(EMACS_INT) < sizeof (EMACS_INT).
21434 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21436 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21443 supposed to be handshaking. (Bug#8556)
21444 Reported by Paul Eggert <eggert@cs.ucla.edu>.
21446 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

21456 * alloc.c (check_sblock, check_string_bytes)
21457 (check_string_free_list): Convert to standard C.
21459 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
21461 * w32.c (emacs_gnutls_push): Fix typo.
21463 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21465 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21466 "cast to pointer from integer of different size".
21468 Improve doprnt and its use in verror. (Bug#8545)
21469 * doprnt.c (doprnt): Document the set of format control sequences
21470 supported by the function. Use SAFE_ALLOCA instead of always
21473 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21474 is one byte too soon. Don't use xrealloc; instead xfree and
21477 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21479 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21482 * gnutls.c: Renamed global_initialized to
21483 gnutls_global_initialized. Added internals for the
21484 :verify-hostname-error, :verify-error, and :verify-flags
21485 parameters of `gnutls-boot' and documented those parameters in the
21486 docstring. Start callback support.
21487 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21488 unless a fatal error occurred. Call gnutls_alert_send_appropriate
21489 on error. Return error code.

21491 (emacs_gnutls_read): Likewise.
21492 (Fgnutls_boot): Return handshake error code.
21493 (emacs_gnutls_handle_error): New function.

21549 changes in globals.h immediately force recompilation.
21550 (TAGS): Depend on $(CURDIR)/m/intel386.h and
21551 $(CURDIR)/s/ms-w32.h.

21561 * doprnt.c: Include limits.h.
21562 (SIZE_MAX): New macro.
21563 (doprnt): Return a size_t value. 2nd arg is now size_t.
21564 Many local variables are now size_t instead of int or unsigned.
21565 Improve overflow protection. Support `l' modifier for integer
21566 conversions. Support %l conversion. Don't assume an EMACS_INT
21567 argument for integer conversions and for %c.
21569 * lisp.h (doprnt): Restore prototype.
21571 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
21572 $(SRC)/character.h.
21574 * Makefile.in (base_obj): Add back doprnt.o.
21576 * deps.mk (doprnt.o): Add back prerequisites.
21577 (callint.o): Depend on character.h.
21579 * eval.c (internal_lisp_condition_case): Include the handler
21580 representation in the error message.
21581 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
21582 when breaking from the loop.
21584 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
21586 * callint.c (Fcall_interactively): When displaying error message
21587 about invalid control letter, pass the character's codepoint, not
21588 a pointer to its multibyte form. Improve display of the character
21589 in octal and display also its hex code.
21591 * character.c (char_string): Use %x to display the (unsigned)
21592 codepoint of an invalid character, to avoid displaying a bogus
21595 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21596 `error', not SYMBOL_NAME itself.
21598 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
21599 character arguments to `error'.
21601 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21602 to `error' in error message about FINAL_CHAR argument. Make sure
21603 FINAL_CHAR is a character, and use %c when it is passed as
21604 argument to `error'.

21668 Define only if needed.
21670 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
21671 by pacifying GCC about it. Maybe it's time to retire it?
21672 * xfaces.c (USG, __TIMEVAL__): Likewise.
21674 * dispextern.h (struct redisplay_interface): Rename param
21675 to avoid shadowing.
21676 * termhooks.h (struct terminal): Likewise.
21677 * xterm.c (xembed_send_message): Likewise.
21679 * insdel.c (make_gap_smaller): Define only if
21680 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
21682 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
21685 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
21686 so that we aren't warned about unused symbols.
21688 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
21690 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
21692 * xfns.c (x_real_positions): Mark locals as initialized.
21694 * xmenu.c (xmenu_show): Don't use uninitialized vars.
21696 * xterm.c: Fix problems found by static analysis with other toolkits.
21697 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
21698 (x_dispatch_event): Declare static if USE_GTK, and
21699 define if USE_GTK || USE_X_TOOLKIT.
21700 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
21701 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
21702 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
21703 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
21705 * xmenu.c (menu_help_callback): Pointer type fixes.
21706 Use const pointers when pointing at readonly data. Avoid pointer

21720 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
21722 * bitmaps: Change bitmaps from unsigned char back to the X11
21723 compatible char. Avoid the old compiler warnings about
21724 out-of-range initializers by using, for example, '\xab' rather
21727 * xgselect.c (xgselect_initialize): Check vs interface
21728 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

21797 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21798 --enable-checking=xmallocoverrun). xfree is now used to
21799 deallocate these memory blocks.

22170 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
22171 it's not optimized away by whole-program optimization.
22172 (message_enable_multibyte, free_misc): Remove.
22173 (catchlist, handlerlist, mark_backtrace):
22174 Declare only if BYTE_MARK_STACK.
22175 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
22176 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
22177 (message_enable_multibyte): Remove decl.
22178 (free_misc, interval_free_list, float_block, float_block_index):
22179 (n_float_blocks, float_free_list, cons_block, cons_block_index):
22180 (cons_free_list, last_marked_index):
22182 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
22183 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
22184 (mark_backtrace): Define only if BYTE_MARK_STACK.
22185 * xdisp.c (message_enable_multibyte): Now static.
22187 Declare Lisp_Object Q* variables to be 'static' if not exported.
22188 This makes it easier for human readers (and static analyzers)
22189 to see whether these variables are used from other modules.
22190 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
22191 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
22192 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
22193 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
22194 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
22195 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
22196 * xmenu.c, xselect.c:
22197 Declare Q* vars static if they are not used in other modules.
22198 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
22199 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
22200 Remove decls of unexported vars.
22201 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
22203 * lisp.h (DEFINE_FUNC): Make sname 'static'.
22205 Make Emacs functions such as Fatom 'static' by default.
22206 This makes it easier for human readers (and static analyzers)
22207 to see whether these functions can be called from other modules.
22208 DEFUN now defines a static function. To make the function external
22209 so that it can be used in other C modules, use the new macro DEFUE.
22210 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
22211 (Finit_image_library):
22212 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
22213 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
22214 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
22215 Remove decls, since these functions are now static.
22216 (Funintern, Fget_internal_run_time): New decls, since these functions
22217 were already external.
22219 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
22220 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
22221 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
22222 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
22223 * keyboard.c, keymap.c, lread.c:
22224 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
22225 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
22226 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
22227 Mark functions with DEFUE instead of DEFUN,
22228 if they are used in other modules.
22229 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22230 decls for now-static functions.
22231 * buffer.h (Fdelete_overlay): Remove decl.
22232 * callproc.c (Fgetenv_internal): Mark as internal.
22233 * composite.c (Fremove_list_of_text_properties): Remove decl.

22237 * doc.c (Fdocumntation_property): New forward static decl.
22238 * eval.c (Ffetch_bytecode): New forward static decl.
22239 (Funintern): Remove extern decl; now in .h file where it belongs.
22240 * fileio.c (Fmake_symbolic_link): New forward static decl.
22241 * image.c (Finit_image_library): New forward static decl.
22242 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
22243 * intervals.h (Fprevious_property_change):
22244 (Fremove_list_of_text_properties): Remove decls.
22245 * keyboard.c (Fthis_command_keys): Remove decl.
22246 (Fcommand_execute): New forward static decl.
22247 * keymap.c (Flookup_key): New forward static decl.
22248 (Fcopy_keymap): Now static.
22249 * keymap.h (Flookup_key): Remove decl.
22250 * process.c (Fget_process): New forward static decl.
22251 (Fprocess_datagram_address): Mark as internal.
22252 * syntax.c (Fsyntax_table_p): New forward static decl.
22253 (skip_chars): Remove duplicate decl.
22254 * textprop.c (Fprevious_property_change): New forward static decl.
22255 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
22257 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
22258 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
22260 * editfns.c (Fformat): Remove unreachable code.
22262 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
22264 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
22267 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22269 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22270 when at ZV. (Bug#8487)
22272 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22274 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22276 * keyboard.c (parse_tool_bar_item): Likewise.
22277 * sound.c (sound_cleanup, alsa_close): Likewise.
22278 * termcap.c (tgetent): Likewise.
22279 * xfns.c (x_default_font_parameter): Likewise.
22280 * xsettings.c (read_and_apply_settings): Likewise.
22282 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22283 (overrun_check_free): Protoize.
22285 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22287 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22288 since callers should never pass a negative size.
22289 Change the signature to match that of plain 'read' and 'write'; see
22290 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22291 * lisp.h: Update prototypes of emacs_write and emacs_read.
22293 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22295 * xdisp.c (redisplay_window): Don't try to determine the character
22296 position of the scroll margin if the window start point w->startp
22297 is outside the buffer's accessible region. (Bug#8468)
22299 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22301 Fix write-region and its subroutines for buffers > 2GB.
22302 * fileio.c (a_write, e_write): Modify declaration of arguments and
22303 local variables to support buffers larger than 2GB.
22304 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22306 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22307 argument, local variables, and return value.
22309 * lisp.h: Update prototypes of emacs_write and emacs_read.
22311 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22313 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22315 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22317 Fix more problems found by GCC 4.6.0's static checks.
22319 * xdisp.c (vmessage): Use a better test for character truncation.
22321 * charset.c (load_charset_map): <, not <=, for optimization,
22322 and to avoid potential problems with integer overflow.
22323 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22324 * casetab.c (set_identity, shuffle): Likewise.
22325 * editfns.c (Fformat): Likewise.
22326 * syntax.c (skip_chars): Likewise.
22328 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22329 This also lets GCC 4.6.0 generate slightly better loop code.
22331 * callint.c (Fcall_interactively): <, not <=, for optimization.
22332 (Fcall_interactively): Count the number of arguments produced,
22333 not the number of arguments given. This is simpler and lets GCC
22334 4.6.0 generate slightly better code.
22336 * ftfont.c: Distingish more carefully between FcChar8 and char.
22337 The previous code passed unsigned char * to a functions like
22338 strlen and xstrcasecmp that expect char *, which does not
22339 conform to the C standard.
22340 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22341 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22342 char * when the C standard requires it.
22344 * keyboard.c (read_char): Remove unused var.
22346 * eval.c: Port to Windows vsnprintf (Bug#8435).
22347 Include <limits.h>.
22348 (SIZE_MAX): Define if the headers do not.
22349 (verror): Do not give up if vsnprintf returns a negative count.
22350 Instead, grow the buffer. This ports to Windows vsnprintf, which
22351 does not conform to C99. Problem reported by Eli Zaretskii.
22352 Also, simplify the allocation scheme, by avoiding the need for
22353 calling realloc, and removing the ALLOCATED variable.
22355 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22357 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22358 But keep the doprint source code for now, as we might revamp it
22359 and use it again (Bug#8435).
22360 * lisp.h (doprnt): Remove.
22361 * Makefile.in (base_obj): Remove doprnt.o.
22362 * deps.mk (doprnt.o): Remove.
22364 error: Print 32- and 64-bit integers portably (Bug#8435).
22365 Without this change, on typical 64-bit hosts error ("...%d...", N)
22366 was used to print both 32- and 64-bit integers N, which relied on
22367 undefined behavior.
22368 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22369 * lisp.h (error, verror): Mark as printf-like functions.
22370 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22371 Report overflow in size calculations when allocating printf buffer.
22372 Do not truncate output string at its first null byte.
22373 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22374 Truncate the output at a character boundary, since vsnprintf does not
22376 * charset.c (check_iso_charset_parameter): Convert internal
22377 character to string before calling 'error', since %c now has the
22379 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22380 overflow when computing char to be passed to 'error'. Do not
22381 pass Lisp_Object to 'error'; pass the integer instead.
22382 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22383 formatted with plain %d.
22385 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22387 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22389 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22391 * xterm.c (x_catch_errors): Remove duplicate declaration.
22393 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22395 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22397 2011-04-10 Jim Meyering <meyering@redhat.com>
22399 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22400 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22401 return ssize_t not "int", and use size_t as the buffer length.
22402 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22403 * gnutls.h: Update declarations.
22404 * process.c (read_process_output): Use ssize_t, to match.
22405 (send_process): Likewise.
22407 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22409 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22411 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22413 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22414 Use unsigned char, to match FcChar8 type definition.
22416 * xterm.c (handle_one_xevent):
22417 * xmenu.c (create_and_show_popup_menu):
22418 * xselect.c (x_decline_selection_request)
22419 (x_reply_selection_request): Avoid type-punned deref of X events.
22421 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22423 Fix some uses of `int' instead of EMACS_INT.
22424 * search.c (string_match_1, fast_string_match)
22425 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22426 (scan_buffer, find_next_newline_no_quit)
22427 (find_before_next_newline, search_command, Freplace_match)
22428 (Fmatch_data): Make some `int' variables be EMACS_INT.
22430 * xdisp.c (display_count_lines): 3rd argument and return value now
22431 EMACS_INT. All callers changed.
22432 (pint2hrstr): Last argument is now EMACS_INT.
22434 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22435 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22436 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22437 (decode_coding_utf_16, decode_coding_emacs_mule)
22438 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
22439 (decode_coding_ccl, decode_coding_charset)
22440 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22441 (decode_coding_iso_2022, decode_coding_emacs_mule)
22442 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22443 <char_offset, last_offset>: Declare EMACS_INT.
22444 (encode_coding_utf_8, encode_coding_utf_16)
22445 (encode_coding_emacs_mule, encode_invocation_designation)
22446 (encode_designation_at_bol, encode_coding_iso_2022)
22447 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22448 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22450 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22451 (encode_invocation_designation): Last argument P_NCHARS is now
22453 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22454 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22456 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22459 * ccl.c (Fccl_execute_on_string): Declare some variables
22462 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22464 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22466 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22468 * process.c (Fformat_network_address): Doc fix.
22470 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22472 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22474 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22476 * keyboard.c (read_char): Call Lisp function help-form-show,
22477 instead of using internal_with_output_to_temp_buffer.
22478 (Qhelp_form_show): New var.
22479 (syms_of_keyboard): Use DEFSYM macro.
22481 * print.c (internal_with_output_to_temp_buffer): Function deleted.
22483 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
22485 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22487 * process.c (Flist_processes): Remove to Lisp.
22488 (list_processes_1): Delete.
22490 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22492 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22494 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22496 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22498 Fix more problems found by GCC 4.6.0's static checks.
22500 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22502 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22504 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22506 * xdisp.c (vmessage): Mark as a printf-like function.
22508 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22510 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22512 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22513 printf-like functions.
22514 (tiff_load): Add casts to remove these marks before passing them
22515 to system-supplied API.
22517 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22519 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22520 This avoids several warnings with gcc -Wstrict-overflow.
22521 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22522 directly, rather than having caller test rule sign. This avoids
22523 some unnecessary tests.
22524 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22525 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22526 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22528 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22529 (xfont_open): Avoid unnecessary tests.
22531 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22533 * composite.h, composite.c (composition_gstring_put_cache):
22534 Use EMACS_INT, not int, for length.
22536 * composite.h (COMPOSITION_DECODE_REFS): New macro,
22537 breaking out part of COMPOSITION_DECODE_RULE.
22538 (COMPOSITION_DECODE_RULE): Use it.
22539 * composite.c (get_composition_id): Remove unused local vars,
22540 by using the new macro.
22542 * textprop.c (set_text_properties_1): Change while to do-while,
22543 since the condition is always true at first.
22545 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22546 (interval_deletion_adjustment): Return unsigned value.
22549 * process.c (list_processes_1, create_pty, read_process_output):
22550 (exec_sentinel): Remove vars that were set but not used.
22551 (create_pty): Remove unnecessary "volatile"s.
22552 (Fnetwork_interface_info): Avoid possibility of int overflow.

22554 (read_process_output): Simplify nbytes computation if buffered.
22556 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
22558 * syntax.c (scan_words): Remove var that was set but not used.
22559 (update_syntax_table): Use unsigned instead of int.
22561 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22562 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22563 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22565 * print.c (print_error_message): Avoid int overflow.
22567 * font.c (font_list_entities): Redo for clarity,
22568 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22570 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22571 (font_score): Avoid potential overflow in diff calculation.
22573 * fns.c (substring_both): Remove var that is set but not used.
22574 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22576 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22578 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22579 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22580 can always succeed if overflow has undefined behavior.
22582 * search.c (boyer_moore, wordify): Remove vars set but not used.
22583 (wordify): Omit three unnecessary tests.
22585 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22586 All callers changed. This avoids the need for an unused var.
22588 * casefiddle.c (casify_region): Remove var that is set but not used.
22590 * dired.c (file_name_completion): Remove var that is set but not used.
22592 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22594 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22595 (Finsert_file_contents): Remove unnecessary code checking fd.
22597 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22598 Check for integer overflow on size calculations.
22600 * buffer.c (Fprevious_overlay_change): Remove var that is set
22603 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22604 Remove vars that are set but not used.
22605 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22606 (timer_check_2): Mark vars as initialized.
22608 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22610 * image.c (lookup_image): Remove var that is set but not used.
22611 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22613 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22614 that are set but not used.
22616 * xfns.c (make_invisible_cursor): Don't return garbage
22617 if XCreateBitmapFromData fails (Bug#8410).
22619 * xselect.c (x_get_local_selection, x_handle_property_notify):
22620 Remove vars that are set but not used.
22622 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

22628 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22629 Check for overflow.
22631 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22632 (map_tty_color) [!defined MSDOS]: Likewise.
22634 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22636 * coding.c: Remove vars that are set but not used.
22637 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

22646 * print.c (print_object): Remove var that is set but not used.
22648 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22649 The gnulib version avoids calling malloc in the usual case,
22650 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22651 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22652 * filelock.c (current_lock_owner): Likewise.
22653 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22654 * sysdep.c: Include allocator.h, careadlinkat.h.
22655 (emacs_no_realloc_allocator): New static constant.
22656 (emacs_readlink): New function.
22657 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22658 ../lib/careadlinkat.h.
22660 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22662 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

22684 do not dereference NULL upon failed strdup
22685 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22686 (ns_get_family): Likewise.
22688 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22690 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22692 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22694 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22697 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22699 Add lexical binding.
22701 * window.c (Ftemp_output_buffer_show): New fun.

22710 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22712 (syms_of_lread): Declare `lexical-binding'.
22714 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22716 * keyboard.c (eval_dyn): New fun.
22717 (menu_item_eval_property): Use it.
22719 * image.c (parse_image_spec): Use Ffunctionp.
22721 * fns.c (concat, mapcar1): Accept byte-code-functions.
22723 * eval.c (Fsetq): Handle lexical vars.
22724 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22725 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22726 (FletX, Flet): Obey lexical binding.
22727 (Fcommandp): Handle closures.
22728 (Feval): New `lexical' arg.
22729 (eval_sub): New function extracted from Feval. Use it almost
22730 everywhere where Feval was used. Look up vars in lexical env.
22732 (Ffunctionp): Move from subr.el.
22733 (Ffuncall): Handle closures.
22734 (apply_lambda): Remove `eval_flags'.
22735 (funcall_lambda): Handle closures and new byte-code-functions.
22736 (Fspecial_variable_p): New function.
22737 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22738 but without exporting it to Lisp.
22740 * doc.c (Fdocumentation, store_function_docstring):
22741 * data.c (Finteractive_form): Handle closures.
22743 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22746 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22748 (exec_byte_code): New function extracted from Fbyte_code to handle new
22749 calling convention for byte-code-functions. Add new byte-codes.
22751 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22753 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22755 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22757 * xdisp.c (redisplay_internal): Fix prototype.
22759 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22761 * xdisp.c (SCROLL_LIMIT): New macro.
22762 (try_scrolling): Use it when setting scroll_limit.
22763 Limit scrolling to 100 screen lines.
22764 (redisplay_window): Even when falling back on "recentering",
22765 position point in the window according to scroll-conservatively,
22766 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22768 (try_scrolling): When point is above the window, allow searching
22769 as far as scroll_max, or one screenful, to compute vertical
22770 distance from PT to the scroll margin position. This prevents
22771 try_scrolling from unnecessarily failing when
22772 scroll-conservatively is set to a value slightly larger than the
22773 window height. Clean up the case of PT below the margin at bottom
22774 of window: scroll_max can no longer be INT_MAX. When aggressive
22775 scrolling is in use, don't let point enter the opposite scroll
22776 margin as result of the scroll.
22777 (syms_of_xdisp) <scroll-conservatively>: Document the
22778 threshold of 100 lines for never-recentering scrolling.

22785 (message_log_check_duplicate): Remove parameters `prev_bol' and
22786 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22787 (redisplay_internal): Remove parameter `preserve_echo_area',
22788 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22790 * indent.c (Fvertical_motion):
22791 * window.c (window_scroll_pixel_based, Frecenter):
22792 Don't pass `need_y_p' to `move_it_by_lines'.
22794 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22796 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22797 steal a few bits to be more compact.
22798 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22799 Remove unneeded casts.
22801 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22803 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22805 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22806 binding" message (bug#7967).
22808 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22810 Fix more problems found by GCC 4.6.0's static checks.
22812 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22813 Remove unused local var.
22815 * editfns.c (Fmessage_box): Remove unused local var.
22817 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22818 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22819 Omit unused local vars.
22820 * window.c (shrink_windows): Omit unused local var.
22821 * menu.c (digest_single_submenu): Omit unused local var.
22822 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22823 Omit unused local var.
22825 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22826 Don't assume string length fits in int.
22827 (keyremap_step, read_key_sequence): Use size_t for sizes.

22831 instead of alloca (Bug#8344).
22833 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22834 (Fbacktrace_frame): Don't assume nframes fits in int.
22836 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

22841 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22843 * cm.c (calccost): Turn while-do into do-while, for clarity.
22845 * keyboard.c (syms_of_keyboard): Use the same style as later
22846 in this function when indexing through an array. This also
22847 works around GCC bug 48267.
22849 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22851 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22853 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22854 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22856 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22857 This avoids undefined behavior on integer overflow, and is a bit
22858 more convenient anyway since it is compared to a size_t variable.
22860 Variadic C functions now count arguments with size_t, not int.
22861 This avoids an unnecessary limitation on 64-bit machines, which
22862 caused (substring ...) to crash on large vectors (Bug#8344).

22872 * fns.c (concat): Likewise.
22873 * frame.c (x_set_frame_parameters): Likewise.
22874 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22875 0 if not found, not -1. All callers changed.
22877 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22878 (stack_copy_size): Now size_t, not int.
22879 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22881 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22883 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22884 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22900 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22901 don't set the hook to nil, but remove the offending function instead.

22903 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22904 Vcommand_hook_internal.

23037 (x_create_tip_frame): Remove unused variable `tem'.
23039 * w32inevt.c (w32_console_read_socket):
23040 Remove unused variable `no_events'.
23042 * w32term.c (x_draw_composite_glyph_string_foreground):
23043 Remove unused variable `width'.
23045 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
23047 * w32term.c (x_set_glyph_string_clipping):
23048 Don't pass uninitialized region to CombineRgn.
23050 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
23052 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
23053 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
23054 (Fx_close_connection): Remove unused variable `i'.

23072 2011-03-23 Julien Danjou <julien@danjou.info>
23074 * term.c (Fsuspend_tty, Fresume_tty):
23075 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
23076 * window.c (temp_output_buffer_show):
23077 * insdel.c (signal_before_change):
23078 * frame.c (Fhandle_switch_frame):
23079 * fileio.c (Fdo_auto_save):

23082 * cmds.c (internal_self_insert):
23083 * callint.c (Fcall_interactively):
23084 * buffer.c (Fkill_all_local_variables):
23085 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
23087 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23088 unconditionally since it does the check itself.
23090 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23092 Fix more problems found by GCC 4.5.2's static checks.
23094 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23095 the first time through the loop, since we know p0 < p1 then.
23096 This also avoids a gcc -Wstrict-overflow warning.
23098 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23099 leading to a memory leak, possible in functions like
23100 load_charset_map_from_file that can allocate an unbounded number
23101 of objects (Bug#8318).
23103 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23104 that could (at least in theory) be that large.
23106 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23107 This is less likely to overflow, and avoids undefined behavior if
23108 overflow does occur. All callers changed. Use strtoul to scan
23109 for the unsigned long integer.
23110 (pint2hrstr): Simplify and tune code slightly.
23111 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
23113 * scroll.c (do_scrolling): Work around GCC bug 48228.
23114 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
23116 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
23117 This also avoids a warning with gcc -Wstrict-overflow.
23118 (validate_x_resource_name): Simplify count usage.
23119 This also avoids a warning with gcc -Wstrict-overflow.
23121 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23124 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23126 * process.c (Fmake_network_process): Use socklen_t, not int,
23127 where POSIX says socklen_t is required in portable programs.
23128 This fixes a porting bug on hosts like 64-bit HP-UX, where
23129 socklen_t is wider than int (Bug#8277).
23130 (Fmake_network_process, server_accept_connection):
23131 (wait_reading_process_output, read_process_output):
23134 * process.c: Rename or move locals to avoid shadowing.

23144 Make tparam.h and terminfo.c consistent.
23145 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23146 Include tparam.h instead, since it declares them.
23147 * cm.h (PC): Remove extern decl; tparam.h now does this.
23148 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23149 * terminfo.c: Include tparam.h, to check interfaces.
23150 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23151 (tparam): Adjust signature to match interface in tparam.h;
23152 this removes some undefined behavior. Check that outstring and len
23153 are zero, which they always are with Emacs.
23154 * tparam.h (PC, BC, UP): New extern decls.
23156 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23157 (xftfont_open): Rename locals to avoid shadowing.
23159 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
23160 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
23161 (OTF_TAG_SYM): Omit macro if not needed.

23169 * xml.c (make_dom): Now static.
23171 * composite.c (composition_compute_stop_pos): Rename local to
23173 (composition_reseat_it): Remove unused locals.
23174 (find_automatic_composition, composition_adjust_point): Likewise.
23175 (composition_update_it): Mark var as initialized.
23176 (find_automatic_composition): Mark vars as initialized,
23177 with a FIXME (Bug#8290).
23179 character.h: Rename locals to avoid shadowing.
23180 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
23181 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
23182 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
23183 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23184 to avoid shadowing.
23186 * textprop.c (property_change_between_p): Remove; unused.
23188 * intervals.c (interval_start_pos): Now static.
23190 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

23193 Rename locals to avoid shadowing.
23195 * sound.c (wav_play, au_play, Fplay_sound_internal):
23196 Fix pointer signedness.
23197 (alsa_choose_format): Remove unused local var.
23198 (wav_play): Initialize a variable to 0, to prevent undefined
23199 behavior (Bug#8278).
23201 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23203 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23205 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23206 clobbering (Bug#8298).
23207 * sysdep.c (sys_subshell): Likewise.
23208 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23210 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23211 This should get cleaned up, so that child_setup has the
23212 same signature on all platforms.
23214 * callproc.c (call_process_cleanup): Now static.
23215 (relocate_fd): Rename locals to avoid shadowing.
23217 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23219 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23220 not to be necessary, and produces flickering.
23222 2011-03-20 Glenn Morris <rgm@gnu.org>
23224 * config.in: Remove file.
23226 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
23228 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
23229 are now in src/globals.h.
23230 (syms_of_minibuf): Remove spurious & from previous change.
23232 2011-03-20 Leo Liu <sdl.web@gmail.com>
23234 * minibuf.c (completing-read-function): New variable.
23235 (completing-read-default): Rename from completing-read.
23236 (completing-read): Call completing-read-function.
23238 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23240 * xfaces.c (Fx_load_color_file):
23241 Read color file from absolute filename (bug#8250).
23243 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23245 * makefile.w32-in: Update dependencies.
23247 2011-03-17 Eli Zaretskii <eliz@gnu.org>
23249 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

23256 (sigchld_handler): Now static.
23258 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
23259 That way, the code declares only the vars that it needs.
23260 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
23261 * s/cygwin.h (PTY_ITERATION): Likewise.
23262 * s/darwin.h (PTY_ITERATION): Likewise.

23268 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
23269 (CONSTANTLIM): Remove; unused.
23270 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
23271 Define only if needed.
23273 * unexelf.c (unexec): Name an expression,
23274 to avoid gcc -Wbad-function-cast warning.
23275 Use a different way to cause a compilation error if anyone uses
23276 n rather than nn, a way that does not involve shadowing.
23277 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23279 * deps.mk (unexalpha.o): Remove; unused.
23281 New file unexec.h, the (simple) interface for unexec (Bug#8267).
23282 * unexec.h: New file.
23283 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
23284 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
23285 Depend on unexec.h.
23286 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
23287 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
23288 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
23289 Change as necessary to match prototype in unexec.h.
23291 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
23293 (back_comment, skip_chars): Mark vars as initialized.

23307 instead of using an uninitialized var.
23308 (font_sort_entities): Mark var as initialized.
23310 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
23312 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

23324 * floatfns.c (domain_error2): Define only if needed.
23325 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
23327 * alloc.c (mark_backtrace): Move decl from here ...

23330 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
23331 (Fdefvar): Rewrite so as not to use empty "else".

23336 * callint.c (quotify_arg, quotify_args): Now static.
23337 (Fcall_interactively): Rename locals to avoid shadowing.
23338 Use const pointer when appropriate.
23340 * lisp.h (get_system_name, get_operating_system_release):

23344 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
23345 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
23346 some of which prompt warnings from gcc -Wbad-function-cast.
23347 (Fformat_time_string, Fencode_time, Finsert_char):
23348 (Ftranslate_region_internal, Fformat):
23349 Rename or remove local vars to avoid shadowing.
23350 (Ftranslate_region_internal): Mark var as initialized.
23352 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
23355 * lisp.h (eassert): Check that the argument compiles, even if
23356 ENABLE_CHECKING is not defined.
23358 * data.c (Findirect_variable): Name an expression, to avoid
23359 gcc -Wbad-function-cast warning.

23367 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
23368 Rename locals to avoid shadowing.
23369 (mark_stack): Move local variables into the #ifdef region where
23371 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
23372 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
23374 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
23375 (GC_STRING_CHARS): Remove; not used.
23376 (Fmemory_limit): Cast sbrk's returned value to char *.
23378 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23379 avoids undefined behavior in theory.

23384 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23385 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23386 to use the following functions instead of these macros.
23387 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23388 EMACS_INT, since callers assume the returned value fits in int.
23389 (upcase1): Likewise, for UPCASE_TABLE.
23390 (uppercasep, lowercasep, upcase): New static inline functions.
23391 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
23392 the race-condition problem in the old DOWNCASE.
23394 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

23396 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
23397 (regex_compile, re_search_2, re_match_2_internal):
23398 Remove unused local vars.
23399 (FREE_VAR): Rewrite so as not to use empty "else",
23400 which gcc can warn about.
23401 (regex_compile, re_match_2_internal): Mark locals as initialized.
23402 (RETALLOC_IF): Define only if needed.
23403 (WORDCHAR_P): Likewise. This one is never needed, but is used
23404 only in a comment talking about a compiler bug, so put inside
23405 the #if 0 of that comment.
23406 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23407 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23410 * search.c (boyer_moore): Rename locals to avoid shadowing.
23411 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
23412 (PREV_CHAR_BOUNDARY): Likewise.
23414 * search.c (simple_search): Remove unused var.
23416 * dired.c (compile_pattern): Move decl from here ...

23424 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
23425 Rename locals to avoid shadowing.
23426 (Fvertical_motion): Mark locals as initialized.
23428 * casefiddle.c (casify_object, casify_region): Now static.
23429 (casify_region): Mark local as initialized.
23431 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
23433 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23434 New macros, so that the caller can use some names other than
23435 gcpro1, gcpro2, etc.
23436 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23438 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23439 argument, for consistency with GCPRO2_VAR, etc: it is now the
23440 prefix of the variable, not the variable itself. All uses
23442 * dired.c (directory_files_internal, file_name_completion):
23443 Rename locals to avoid shadowing.
23445 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23446 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23447 dired.c's scmp function, had undefined behavior.
23448 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23449 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23450 * buffer.h: ... to here, because these macros use current_buffer,
23451 and the new implementation with inline functions needs to have
23452 current_buffer in scope now, rather than later when the macros
23454 (downcase, upcase1): New static inline functions.
23455 (DOWNCASE, UPCASE1): Reimplement using these functions.
23456 This avoids undefined behavior in expressions like
23457 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23458 from race conditions in accessing the global variables
23459 case_temp1 and case_temp2.
23460 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23461 * lisp.h (case_temp1, case_temp2): Remove their decls.
23462 * character.h (ASCII_CHAR_P): Move from here ...
23463 * lisp.h: ... to here, so that the inline functions mentioned
23464 above can use them.
23466 * dired.c (directory_files_internal_unwind): Now static.
23468 * fileio.c (file_name_as_directory, directory_file_name):
23469 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
23471 (file_name_as_directory): Use const pointers when appropriate.
23472 (Fexpand_file_name): Likewise. In particular, newdir might
23473 point at constant storage, so make it a const pointer.
23474 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23475 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23477 (Fset_file_times, Finsert_file_contents, auto_save_error):
23478 Rename locals to avoid shadowing.
23480 * minibuf.c (choose_minibuf_frame_1): Now static.
23481 (Ftry_completion, Fall_completions): Rename or remove locals
23482 to avoid shadowing.
23484 * marker.c (bytepos_to_charpos): Remove; unused.
23486 * lisp.h (verify_bytepos, count_markers): New decls,
23487 so that gcc does not warn that these functions aren't declared.

23910 All callers of tparam changed to use tparam's actual API.
23911 * tparam.c (tparam1, tparam, tgoto):
23912 Use const pointers where appropriate.
23914 * cm.c (calccost, cmgoto): Use const pointers where appropriate.
23915 * cm.h (struct cm): Likewise.
23916 * dispextern.h (do_line_insertion_deletion_costs): Likewise.
23917 * scroll.c (ins_del_costs, do_line_insertion_deletion_costs): Likewise.
23918 * term.c (tty_ins_del_lines, calculate_costs, struct fkey_table):
23919 (term_get_fkeys_1, append_glyphless_glyph, produce_glyphless_glyph):
23920 (turn_on_face, init_tty): Likewise.
23921 * termchar.h (struct tty_display_info): Likewise.
23923 * term.c (term_mouse_position): Rename local to avoid shadowing.
23925 * alloc.c (mark_ttys): Move decl from here ...
23926 * lisp.h (mark_ttys): ... to here, so that it's checked against defn.
23928 2011-03-11 Andreas Schwab <schwab@linux-m68k.org>
23930 * .gdbinit (pwinx, xbuffer): Fix access to buffer name.
