38 * xdisp.c (row_for_charpos_p): New function, with code of
39 cursor_row_p, but accepts an additional argument CHARPOS instead
40 of using a hardcoded PT.
41 (cursor_row_p): Call row_for_charpos_p with 2nd argument PT.
42 (row_containing_pos): Call row_for_charpos_p instead of partially
43 doing the same. Fixes cursor positioning under longlines-mode
44 when longlines-show-effect includes more than one newline, when
45 moving the cursor vertically up.
47 2013-05-08 Juanma Barranquero <lekktu@gmail.com>

65 * unexelf.c: Don't assume ElfW (Half) fits in int.
66 (entry_address, find_section, unexec): Use ptrdiff_t, not int,
67 when dealing with ElfW (Half) values, since they can exceed 2**31
68 on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
69 (entry_address): Omit unused NUM arg. All uses changed.
71 2013-05-07 Juri Linkov <juri@jurta.org>

124 Xatom_net_current_desktop.
126 * xterm.c (x_term_init): Initialize dpyinfo->Xatom_net_workarea
127 and dpyinfo->Xatom_net_current_desktop.
129 2013-05-06 Eli Zaretskii <eliz@gnu.org>
131 * xdisp.c (pos_visible_p): Use the special code for finding the
132 beginning of a display property or overlay for any "replacing"
133 display property, not just for display strings. This solves
134 incorrect reporting of position by posn-at-point. (Bug#14241)
136 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
138 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
139 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
140 Verify that ElfW (Half) fits in int.
141 (fatal): Use same signature as lisp.h.
142 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
143 configure and build with -DUNEXELF_DEBUG without worrying about
144 other modules that use DEBUG.
145 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
146 possibly-wide integers now uses it instead of plain fprintf.
147 (entry_address): New function, which avoids problems with 32-bit
148 overflow on 64-bit hosts.
149 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
150 (round_up): Don't assume the remainder fits in int.
151 (find_section): Use bool for boolean. Simplify debug code.
152 (unexec): Don't assume file sizes fit in int or size_t.
153 Omit unnecessary trailing newline in 'fatal' format.
154 Use strerror rather than outputting decimal error number.
155 Remove unused code when emacs is not defined;
156 this file relies on Emacs now.
157 Don't assume e_phnum and e_shnum are positive.
159 * regex.c: Fix problems when DEBUG is defined.
160 (extract_number, extract_number_and_incr): Define regardless of
161 whether DEBUG is defined; that's simpler and makes the code less
162 likely to go stale in the normal case when DEBUG is not defined.
163 Return int rather than taking an int * arg. All callers changed.
164 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
165 Remove, replacing with ...
166 (DEBUG_PRINT): New macro. All callers changed.
167 (DEBUG_COMPILES_ARGUMENTS): New macro.

172 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
173 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
174 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
175 Don't assume ptrdiff_t, size_t, and long are the same width as int.
176 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
177 This matters only when DEBUG is defined.
179 2013-05-05 Eli Zaretskii <eliz@gnu.org>
181 * xdisp.c (set_iterator_to_next): Set the
182 ignore_overlay_strings_at_pos_p flag only if we are _really_
183 iterating over an overlay string, as indicated by the
184 current.overlay_string_index member. (Bug#14306)
186 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
188 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
189 to where it is used, to avoid autorelease issues (Bug#14050).
191 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
193 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
194 * fileio.c (syms_of_fileio): Implement this.
195 * filelock.c (create_lock_file): If symbolic links don't work, so
196 we use a regular file as a lock file, do not fsync the lock file;
199 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
201 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.

210 Use parentheses to disambiguate last part of the condition.
212 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
213 assertion violations. (Bug#14062)
215 2013-05-01 David Reitter <david.reitter@gmail.com>
217 * nsfns.m (ns_tooltip): Initialize.
219 2013-04-28 Eli Zaretskii <eliz@gnu.org>
221 * coding.c (decode_coding_gap): Don't remove the character before
222 a newline unless it's a CR character. (Bug#14287)
224 2013-04-28 Dan Nicolaescu <dann@gnu.org>
226 * dispextern.h (struct face): Move enum face_underline_type

236 2013-04-27 Juri Linkov <juri@jurta.org>
238 * callint.c (Fcall_interactively): Call `Qread_number' for
239 interactive code letter `n' instead of using duplicate code.
242 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
244 * systime.h (make_timeval): Declare as 'const'.
246 2013-04-27 Kenichi Handa <handa@gnu.org>

251 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
253 Port better to AIX (Bug#14258).
254 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,

265 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
266 Without this fix, "make distclean" leaves stamp-h1 behind.
268 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
270 * w32fns.c (w32_fullscreen_rect): New function to compute the
271 window rectangle for the given fullscreen mode.
272 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
273 longer tunes the window size. This keeps the window's edges flush
274 with the screen and allows the taskbar to hide itself in fullboth.
276 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
277 window decorations and uses the entire screen.
279 * w32term.h (w32_fullscreen_rect) Add prototype.
280 (struct w32_output): Replace normal_width, normal_height,
281 normal_top, and normal_left members with a single normal_placement

299 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
300 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
301 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
302 parentheses where appropriate.
304 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
306 * keyboard.c (timer_start_idle): Remove no-longer-used local.
308 2013-04-14 Eli Zaretskii <eliz@gnu.org>
310 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
311 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
312 Mention in the doc string that setting these variables takes
313 effect only after a call to set-window-buffer. (Bug#14200)
315 2013-04-13 Eli Zaretskii <eliz@gnu.org>
317 * indent.c (Fvertical_motion): Don't consider display strings on
318 overlay strings as display strings on the buffer position we
319 started from. This prevents vertical cursor motion from jumping
320 more than one line when there's an overlay string with a display
321 property at end of line.
322 Reported by Karl Chen <Karl.Chen@quarl.org> in
323 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.

328 already selected (bug#14191).
330 2013-04-11 Eli Zaretskii <eliz@gnu.org>
332 * window.c (Fwindow_end): Test more flags, including the buffer's
333 last_overlay_modified flag, to determine whether the window's
334 display is really up-to-date. Prevents the function from
335 returning a stale value. (Bug#14170)
336 (Fwindow_line_height): Fix the test for up-to-date-ness of the
339 2013-04-10 Eli Zaretskii <eliz@gnu.org>
341 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
342 garbaged only if it is not already the top frame on its TTY.
343 This prevents flickering due to constant redrawing of TTY frames when
344 there are GUI frames open in the same session. (Bug#13864)
346 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
348 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
349 of marking the idle timers directly.
351 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
353 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
356 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>

375 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
378 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
380 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
381 This bug was introduced by my 2013-02-25 change that simplified
382 data_start configuration. Without this change, on GNU/Linux
383 an Emacs configured with --enable-profiling fails immediately
384 due to a profiler signal.
385 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
386 with these flags. On platforms where special flags are needed
387 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
388 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
389 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
391 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>

399 * frame.h (decode_window_system_frame, window_system_available):
400 ...here, add new prototypes.

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

596 Use contents slot, not buffer, where appropriate.
597 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
598 to avoid deleted windows. Use contents slot instead of buffer.
599 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
600 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:

961 Simplify debugging check and convert to eassert. Adjust comment.
962 (pp_cache): Put under ENABLE_CHECKING.
964 2013-03-14 Eli Zaretskii <eliz@gnu.org>
966 * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
967 and incorrect code. Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
969 (w32fullscreen_hook): If the frame is visible, reset
970 f->want_fullscreen flag after changing the frame size. If the
971 frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
974 2013-03-13 Daniel Colascione <dancol@dancol.org>
976 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
977 too so that these builds can use Cygwin's file conversion
978 functions. (We've been building and linking cygw32.o all along
979 and just not using it.)
981 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
983 File synchronization fixes (Bug#13944).
984 * Makefile.in (LIB_FDATASYNC): New macro.
986 * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
987 * fileio.c (Fwrite_region, write_region_inhibit_fsync):
988 Don't worry about HAVE_FSYNC, since a substitute fsync is
989 available if the system lacks one.
990 (Fwrite_regin): Retry fsync if interrupted.
992 2013-03-13 Eli Zaretskii <eliz@gnu.org>
994 * w32term.c (w32_read_socket): If the Emacs frame is being
995 activated, call w32fullscreen_hook, to make sure the new frame
996 dimensions are in effect. (Bug#13937)
998 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
1000 * xdisp.c (init_iterator): Simplify because both character and byte
1001 positions are either specified or -1. Add eassert. Adjust comment.
1002 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
1003 character and byte positions can be obtained from marker.
1005 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>
1007 Static checking by Sun C 5.12.

1020 a function pointer type; the C Standard requires this.
1022 * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
1023 Include <sys/param.h> unconditionally, as that works elsewhere and
1024 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
1025 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
1028 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>

1057 common file dialog code.
1059 * w32fns.c (Ffile_system_info): Remove from cygw32 builds, which
1060 can just use du like other systems.
1062 * coding.c (from_unicode_buffer): Declare.
1063 * coding.c (from_unicode_buffer): Implement.
1065 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>
1067 * lread.c: Minor cleanup.

1109 2013-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
1111 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
1112 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1113 from Elisp via unread-command-events.
1115 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1116 functions to mean "no change".
1118 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1120 region-cache.c, scroll.c, search.c: Use bool for booleans.
1121 * lisp.h (compile_pattern):

1126 (search_regs_saved, Fregexp_quote):
1127 Use bool for boolean.
1128 * region-cache.c (region_cache_forward, region_cache_backward):
1129 Fix comments to match code: these functions return int, not boolean.
1131 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1133 * search.c (find_newline): Accept start and end byte positions
1134 as arguments and allow -1 if not known.
1135 (find_newline_no_quit): Likewise for start position.
1136 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
1137 * bidi.c (bidi_find_paragraph_start): Pass byte position to
1138 find_newline_no_quit, thus eliminating CHAR_TO_BYTE.
1139 * editfns.c (Fconstrain_to_field): Break long line.
1140 Adjust call to find_newline.
1141 * indent.c (vmotion): Adjust calls to find_newline_no_quit.
1142 Use DEC_BOTH to start next search from the previous buffer
1143 position, where appropriate.
1144 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1145 (get_visually_first_element, move_it_vertically_backward): Likewise.
1146 Obtain byte position from the display iterator, where appropriate.
1148 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>
1150 print.c, process.c: Use bool for booleans.
1151 * lisp.h (wait_reading_process_output):
1152 * print.c (print_output_debug_flag, PRINTDECLARE, printchar)
1153 (strout, debug_output_compilation_hack, float_to_string, print)

1166 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1168 * bidi.c (bidi_fetch_char): Swap first and second arguments
1169 to match other functions accepting character and byte positions.
1171 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.
1172 (bidi_paragraph_init): Likewise. Use DEC_BOTH which is faster
1173 when you need just to move to the previous buffer position.
1174 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1176 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1189 Adjust comments, style and calls to compute_motion.
1190 (Fvertical_motion): Adjust call to vmotion.
1191 * window.c (Fdelete_other_windows_internal): Record window start
1192 byte position and adjust call to vmotion.
1193 (window_scroll_line_based): Likewise with call to compute_motion.
1195 (Frecenter): Adjust calls to vmotion.
1197 2013-03-07 Dmitry Antipov <dmantipov@yandex.ru>
1199 * lisp.h (list2i, list3i): New functions.
1200 (list4i): Move from window.c and make LISP_INLINE.
1201 * editfns.c (make_lisp_time):
1202 * fns.c (Flocale_info):

1213 2013-03-06 Eli Zaretskii <eliz@gnu.org>
1215 * search.c (find_newline_no_quit): Rename from find_next_newline.
1218 * lisp.h (find_newline_no_quit): Rename prototype.
1220 * xdisp.c (back_to_previous_line_start)

1222 (move_it_vertically_backward): Callers of find_newline_no_quit changed.
1223 * indent.c (vmotion): Callers of find_newline_no_quit changed.
1224 * bidi.c (bidi_find_paragraph_start): Callers of
1225 find_newline_no_quit changed.

1230 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1232 Coding system support cleanup and minor refactoring.
1233 * coding.h (enum coding_result_code): Remove
1234 CODING_RESULT_INCONSISTENT_EOL and CODING_RESULT_INSUFFICIENT_MEM.
1235 (toplevel): Remove unused CODING_MODE_INHIBIT_INCONSISTENT_EOL.
1236 (CODING_MODE_LAST_BLOCK, CODING_MODE_SELECTIVE_DISPLAY)
1237 (CODING_MODE_DIRECTION, CODING_MODE_FIXED_DESTINATION)
1238 (CODING_MODE_SAFE_ENCODING): Rearrange bit values.

1245 (decode_coding, encode_coding): Add USE_SAFE_ALLOCA and SAFE_FREE.
1246 (decode_coding_object): Simplify since xrealloc never returns NULL.
1249 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1251 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1252 * sysdep.c (list_system_processes)
1253 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1254 Make it a stub in this case; otherwise the build might fail,
1255 and this code hasn't been tested on such hosts anyway.
1256 Problem reported by Nelson H. F. Beebe in
1257 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1258 and analyzed by Jérémie Courrèges-Anglas in
1259 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1261 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1263 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1264 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1265 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1266 * bidi.c (bidi_find_paragraph_start): Likewise.
1267 * indent.c (vmotion): Likewise.
1269 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1271 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1272 * filelock.c: Include <c-ctype.h>.
1273 (MAX_LFINFO): New top-level constant.
1274 (lock_info_type): Remove members pid, boot_time. Add members at,
1275 dot, colon. Change user member to be the entire buffer, not a
1276 pointer. This allows us to handle the case where a foreign
1277 pid or boot time exceeds the local range. All uses changed.
1278 (LINKS_MIGHT_NOT_WORK): New constant.
1279 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1280 (defined_WINDOWSNT): Remove.
1281 (MAKE_LOCK_NAME, file_in_lock_file_name):
1282 Always use .#FILE (not .#-FILE) for the file lock,
1283 even if it is a regular file.
1284 (rename_lock_file): New function.
1285 (create_lock_file): Use it.
1286 (create_lock_file, read_lock_data):
1287 Prefer a symbolic link for the lock file, falling back on a
1288 regular file if symlinks don't work. Do not try to create
1289 symlinks on MS-Windows, due to security hassles. Stick with
1290 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1291 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1292 host may be using a Windowsish file system, and cannot use
1293 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1294 doesn't work. Don't fail merely because of a symlink-contents
1295 length limit in the current file system; fall back on regular
1296 files. Increase the symlink contents length limit to 8 KiB, this
1297 should be big enough for any real use and doesn't crunch the
1299 (create_lock_file, lock_file_1, read_lock_data):
1300 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1301 (lock_file_1): Return error number, not bool. All callers changed.
1302 (ELOOP): New macro, if not already defined.
1303 (read_lock_data): Return size of lock file contents, not Lisp object.
1304 All callers changed. Handle a race condition if some other process
1305 replaces a regular-file lock with a symlink lock or vice versa,
1306 while we're trying to read the lock.
1307 (current_lock_owner): Parse contents more carefully, to help avoid
1308 confusing a regular-file lock with some other application's use
1309 of the file. Check for lock file contents being too long, or
1310 not parsing correctly.
1311 (current_lock_owner, lock_file):
1312 Allow foreign pid and boot times that exceed the local range.
1313 (current_lock_owner, lock_if_free, lock_file):
1314 Simplify allocation of lock file contents.
1315 * w32.c (sys_rename_replace): New function, containing most of
1316 the contents of the old sys_rename.
1317 (sys_rename): Use it.
1318 (fchmod): New dummy function.
1319 * w32.h (sys_rename_replace, fchmod): New decls.
1321 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1323 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1324 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1325 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1326 <dmantipov@yandex.ru>.
1328 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1330 * composite.c (get_composition_id, fill_gstring_header):
1331 Use make_uninit_vector where appropriate.
1332 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1333 * xselect.c (clean_local_selection_data): Likewise.
1335 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1337 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1338 * image.c (imagemagick_load_image): Calculate height and width
1339 after flattening the image, not before.
1341 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1343 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1344 * ftfont.c (ftfont_shape_by_flt): Likewise.
1345 * w32uniscribe.c (uniscribe_shape): Likewise.
1347 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1349 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1350 The old approach, which fell back on DIR/.#FILE.0 through
1351 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1352 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1353 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1354 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1355 because the locking mechanism was never reliable in that case).
1356 This patch fixes this and other bugs discovered by a code
1357 inspection that was prompted by
1358 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1359 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1360 to avoid interoperability problems between the MS-Windows and
1361 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1362 instances of Emacs now ignore each others' locks.
1363 * filelock.c (defined_WINDOWSNT): New constant.
1364 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1365 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1366 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1367 regular files on MS-Windows hosts.
1368 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1369 Use SAFE_ALLOCA to avoid problems with long file names.
1370 (MAX_LFINFO): Now a local constant, not a global macro.
1371 (IS_LOCK_FILE): Remove.
1372 (lock_file_1): Don't inspect errno if symlink call succeeds;
1373 that's not portable.
1374 (lock_file): Document that this function can return if lock
1376 (lock_file): Don't access freed storage.
1378 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1380 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1382 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1384 * textprop.c: Use bool for booleans.
1385 (validate_interval_range, Fadd_text_properties)
1386 (Fremove_text_properties): Prefer bool to int when either works.
1388 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1390 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1391 If the interval tree changes as a side effect of calling
1392 modify_region, re-do processing starting from the call to
1393 validate_interval_range. (Bug#13743)
1395 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1397 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1400 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1402 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1403 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1404 access to the lock file until it is written and closed.
1407 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1409 * callint.c (Qcall_interactively):
1410 * macros.c (Qexecute_kbd_macro):

1415 * window.c (Frecenter): Tiny docstring enhancement.
1417 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1419 Minor textprop integer cleanup.
1420 * intervals.h, textprop.c (add_text_properties_from_list):
1421 Return void, not int, since nobody uses the return value.
1422 * textprop.c (validate_plist, add_properties, remove_properties)
1423 (Fadd_text_properties):
1424 Don't assume list length fits in int.
1425 (interval_has_all_properties, interval_has_some_properties)
1426 (interval_has_some_properties_list, add_properties, remove_properties)

1436 Implement CLASH_DETECTION for MS-Windows.
1438 * filelock.c [WINDOWSNT]: Include w32.h.

1440 function of that name. Up-case the macro arguments.
1441 (IS_LOCK_FILE): New macro.
1442 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1443 (create_lock_file): New function, with body extracted from

1446 the lock information as its contents.
1447 (read_lock_data): New function, on Posix platforms just calls
1449 [WINDOWSNT]: Read the lock info from the file.
1450 (current_lock_owner): Call read_lock_data instead of calling
1451 emacs_readlinkat directly.
1452 (lock_file) [WINDOWSNT]: Run the file name through
1455 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1456 just check if the process by that PID exists.
1458 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1459 also present, as doing so will fail to error out if the file
1462 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1464 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1465 (Fremove_list_of_text_properties): Skip all of the intervals in
1466 the region between START and END that already have resp. don't
1467 have the requested properties, not just the first one.
1468 Add assertions that the loop afterwards always modifies the
1469 properties. (Bug#13743)
1471 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1473 * callint.c (Fcall_interactively): Use the right lexical environment

1482 (START_FILES): Remove. All uses removed.
1483 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
1484 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
1485 (buildobj.h): Use it.

1487 (temacs$(EXEEXT)): Use $(ALLOBJS).
1488 * autodeps.mk (ALLOBJS): Move to Makefile.in.
1489 * deps.mk (vm-limit.o):
1490 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
1491 Do not depend on mem-limits.h.
1492 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
1493 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)

1498 (make_hdr): Use DATA_START instead of start_of_data.
1499 * vm-limit.c: Move most of mem-limits.h's contents here.
1500 (data_start): New decl. It's OK if this is approximate,
1501 so simplify-away some unnecessary exactness.
1502 (POINTER): Remove; all uses removed.
1503 (data_space_start): Now char *, to avoid casts.
1504 (exceeds_lisp_ptr): New function, replacing the old
1505 EXCEEDS_LISP_PTR macro. All uses changed.

1520 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00533.html>
1521 and diagnosed by Andreas Schwab in
1522 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
1524 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1526 Assume C89 or better.
1527 * ralloc.c (SIZE, POINTER, NIL):
1528 * vm-limit.c (POINTER):
1529 Remove, replacing all uses with C89 equivalents. These old
1530 symbols were present only for porting to pre-C89 platforms.
1532 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1534 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1535 This avoids warning messages reported as part of Bug#13546.
1537 2013-02-21 Ken Brown <kbrown@cornell.edu>
1539 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
1541 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
1543 * sheap.c (report_sheap_usage): Prefer message1_nolog.
1545 * keyboard.c (Qcommand_execute): New var.
1546 (command_loop_1, read_char): Use it.
1547 (Fcommand_execute): Remove, replace by an Elisp implementation.

1550 2013-02-19 Daniel Colascione <dancol@dancol.org>
1552 * sheap.c (report_sheap_usage): Use message, not message1, so
1553 that we don't try to create a buffer while we're in the middle
1554 of dumping Emacs. Explain why.
1556 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1558 * search.c (find_newline): Return byte position in bytepos.

1568 (get_visually_first_element, move_it_vertically_backward):
1569 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
1571 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1573 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1574 resources were not orderly released.
1576 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1578 * xdisp.c (x_draw_vertical_border): For a window that is neither
1579 the leftmost nor the rightmost, redraw both the left and the right
1580 vertical borders. (Bug#13723)
1582 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>

1600 2013-02-16 Eli Zaretskii <eliz@gnu.org>
1602 * w32.c (sys_chown): Remove unused function.
1604 * w32term.c <input_signal_count>: Declare 'volatile'
1605 unconditionally. (Bug#9066)
1607 * w32.c (set_errno): Reset h_errno and don't set it to any other
1608 value. Set errno instead.
1609 (check_errno): Reset h_errno.
1610 (sys_socket, socket_to_fd, sys_bind, sys_connect)
1611 (sys_gethostname, sys_getservbyname, sys_getpeername)
1612 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1613 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
1615 (sys_gethostbyname): Set h_errno only errors detected.
1617 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1619 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
1621 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1623 * keyboard.c (read_char): Fix calculation of auto-save time out
1624 when auto-save-timeout is less than 4. (Bug#13720)
1626 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1627 time. Improve diagnostics in DebPrint. (Bug#13546)

1632 (sys_accept, sys_recvfrom, sys_sendto, fcntl): In case of failure,
1633 make sure errno is set to an appropriate value. (Bug#13546)
1634 (socket_to_fd): Add assertion against indexing fd_info[] with a
1635 value that is out of bounds.
1636 (sys_accept): If fd is negative, do not set up the child_process
1637 structure for reading.
1639 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1641 * composite.c (fill_gstring_header): Remove useless prototype.

1648 (get_overlay_arrow_glyph_row, display_mode_element):
1649 (decode_mode_spec_coding, message3):
1650 * xfaces.c (face_at_string_position): Use bool for booleans.
1653 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1655 Fix AIX port (Bug#13650).
1656 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1657 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1658 was #undeffed earlier, so it cannot be used as a macro here.
1659 Use the constant and not the macro.
1661 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1663 * w32proc.c (new_child): If no vacant slots are found in
1664 child_procs[], make another pass looking for slots whose process
1665 has exited or died. (Bug#13546)
1667 * w32.c (sys_pipe): When failing due to file descriptors above
1668 MAXDESC, set errno to EMFILE.
1669 (_sys_read_ahead): Update cp->status when failing to read serial
1670 communications input, so that the status doesn't stay at
1671 STATUS_READ_IN_PROGRESS. (Bug#13546)
1673 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1675 * gtkutil.c (tb_size_cb): New function.
1676 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1678 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1680 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1683 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1685 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1687 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1693 Break long line. Remove useless prototype and format comment.
1695 2013-02-13 Glenn Morris <rgm@gnu.org>
1697 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1699 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1701 Improve AIX port some more (Bug#13650).
1702 With this, it should be as good as it was in 23.3, though it's
1703 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1704 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1705 * unexaix.c (start_of_text): Remove.
1706 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1707 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1708 (orig_load_scnptr, orig_data_scnptr):
1709 Now off_t, not long, since they are file offsets.
1710 (make_hdr): Use _data, not start_of_data ().
1711 This is the key part of the fix.
1712 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1713 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1715 * pre-crt0.c (data_start): Initialize to 1.
1716 This ports to compilers that optimize the external declaration
1717 'int x = 0;' as if it were 'int x;' to shrink the executable.
1719 Improve AIX port (Bug#13650).
1720 This doesn't fix the bug, but it makes progress: Emacs builds now.
1721 * unexaix.c: Include inttypes.h, stdarg.h.
1722 (report_error, report_error_1): Mark as _Noreturn.
1723 (report_error): Don't report the wrong errno.
1724 (report_error_1): Now varargs. All callers changed.
1725 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1726 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1727 (write_ptr): Use %p to print address rather than %lx and a cast
1728 to unsigned long. Grow buffer a bit, to be safer.
1730 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1732 * bidi.c (bidi_resolve_neutral): After finding the next
1733 non-neutral character, accept NEUTRAL_ON type as well, because
1734 directional control characters, such as LRE and RLE, have their
1735 type converted to that by bidi_resolve_weak. This avoids aborts
1736 when LRE/RLE follows a run of neutrals.
1737 (bidi_move_to_visually_next): Assert that return value of
1738 bidi_peek_at_next_level is non-negative. Negative values will
1741 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1743 Minor getenv-related fixes.
1744 * callproc.c (Fcall_process_region) [!DOS_NT]:
1745 Avoid unnecessary duplicate call to getenv.
1746 * callproc.c (init_callproc):
1747 * dispnew.c (init_display):
1748 * sysdep.c (sys_subshell):
1749 Omit unnecessary cast of getenv or egetenv.
1751 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1753 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1754 Update dependencies.
1756 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1758 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1760 (display_line): Set w->region_showing to the value of
1761 it->region_beg_charpos, not to -1. This fixes redisplay
1762 optimization when cursor is moved up after M->. (Bug#13623)
1764 (try_scrolling): Scroll text up more if point is too close to ZV
1765 and inside the scroll margin. This makes sure point is moved
1766 outside the scroll margin in these cases.
1768 * window.h (struct window): region_showing can no longer be
1771 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1773 Tune by using memchr and memrchr.
1774 * doc.c (Fsnarf_documentation):
1775 * fileio.c (Fsubstitute_in_file_name):
1776 * search.c (find_newline, scan_newline):
1777 * xdisp.c (pos_visible_p, display_count_lines):
1778 Use memchr and memrchr rather than scanning byte-by-byte.
1779 * search.c (find_newline): Rename from scan_buffer.
1780 Omit first arg TARGET, as it's always '\n'. All callers changed.
1782 Clean up read_key_sequence a tiny bit more.
1783 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1784 (read_key_sequence): Remove unused locals.
1786 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1788 Clean up read_key_sequence a bit; reread active keymaps after first event.
1789 * keyboard.c (read_char, read_char_x_menu_prompt)
1790 (read_char_minibuf_menu_prompt):
1791 Replace nmaps+maps with a single `map' arg.
1792 (follow_key): Operate on a single map.
1793 (active_maps): New function.
1794 (test_undefined): Also return true for nil bindings.
1795 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1796 a single (composed) keymap. Remember `first_event' to choose the right
1797 set of active keymaps. Recompute the set of keymaps after receiving
1798 the first event. Remove GOBBLE_FIRST_EVENT.
1799 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1800 * keyboard.h (read_char): Update declaration.
1801 * lread.c (read_filtered_event): Adjust call to read_char.
1803 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1805 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1806 Don't use the limitation on backwards movement when lines are truncated
1807 in the window. (Bug#13675)
1809 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1811 * marker.c (set_marker_internal): If desired position is passed
1812 as a marker, avoid call to buf_charpos_to_bytepos.
1813 * window.c (Fset_window_point): Omit redundant type checking.
1814 (Fset_window_start): Likewise. Format comment.
1815 (window_scroll_pixel_based): Use set_marker_restricted_both
1816 with character and byte positions obtained from an iterator.
1817 (Fset_window_configuration): Use set_marker_restricted_both.
1818 * xdisp.c (message_dolog): Likewise.
1820 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1822 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1823 When text lines are longer than window's screen lines, don't move back
1824 too far. This speeds up some redisplay operations. (Bug#13675)
1826 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1828 * syntax.c (scan_sexps_forward): Fix byte position calculation
1829 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1831 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1833 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1834 that was not needed.
1836 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1838 Minor hashing refactoring.
1839 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1840 (sxhash_float): Return EMACS_UINT, for consistency with the other
1842 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1843 non-static inline function and therefore can't use static vars.
1844 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1845 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1846 with the other hash functions.
1848 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1850 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1851 XXXXXX part of the temporary file pattern is not downcased even
1852 when w32-downcase-file-names is non-nil. (Bug#13661)
1854 * xdisp.c (decode_mode_spec): Remove handling of %t.
1856 * msdos.c (careadlinkatcwd): Remove.

1861 (read1): Use it. Use getc instead of READCHAR to read bytes.
1862 (load_each_byte): Remove. Update users.
1864 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1866 * search.c (scan_buffer): Calculate end byte position just once.
1867 (scan_newline): Do not recalculate start_byte.
1868 (search_command): Use eassert.
1869 * syntax.c (struct lisp_parse_state): New member location_byte.
1870 (scan_sexps_forward): Record from_byte and avoid redundant
1871 character to byte position calculation ...
1872 (Fparse_partial_sexp): ... here. Break too long line.
1874 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1876 * lisp.h (make_uninit_vector): New function.
1877 * alloc.c (Fvector, Fmake_byte_code):

1896 argument is known to be a vector.
1897 * fns.c (Flocale_info): Likewise for ASET.
1898 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1899 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1901 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1903 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1906 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.

1911 (ns_last_use_native_fullscreen): New variable.
1912 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.
1913 (x_set_window_size): Do not take title bar and tool bar into account
1914 if isFullscreen returns YES.
1915 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1916 (check_native_fs): New function.
1917 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1918 (ns_term_init): Remove NEW_STYLE_FS.

1920 and tool bar if isFullscreen returns NO.
1921 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1922 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1923 with HAVE_NATIVE_FS.

1931 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1932 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1933 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1934 (syms_of_nsterm): Add ns-use-native-fullscreen.
1936 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1938 * fileio.c (Qchoose_write_coding_system): Now static.
1940 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1942 * xdisp.c (window_buffer_changed): region_showing can be negative,
1943 which still means region is being displayed.
1944 (redisplay_internal): Resurrect code that forced redisplay of the
1945 whole window when showing region and the mark has changed.
1946 Record the new mark position to allow redisplay optimizations.
1947 (display_line): If it->region_beg_charpos is non-zero, set the
1948 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1950 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1951 not bitfield of 1 bit.
1953 2013-02-03 Daniel Colascione <dancol@dancol.org>
1955 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1956 daemon mode works on cygw32 when Emacs is installed and not just
1959 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1961 Avoid file time stamp bug on MS-Windows (Bug#13149).
1962 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1963 as FAT32 doesn't update time stamps when truncating them.
1964 Also, check that a file time stamp is not a multiple of 100 ns;
1965 this should catch all instances of the problem on MS-Windows,
1966 as its native file system resolution is 100 ns or worse, and
1967 checking for a non-multiple of 100 ns should impose only a small
1968 overhead on systems with ns resolution.
1970 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1972 Avoid encoding file names on MS-Windows when they need to be run
1973 through dostounix_filename.
1974 * w32.c (normalize_filename): Accept an additional argument
1975 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1976 downcase it even if w32-downcase-file-names is non-nil.
1977 (dostounix_filename): Accept an additional argument MULTIBYTE and
1978 pass it to normalize_filename.
1979 (emacs_root_dir): Adjust.
1981 * msdos.h (dostounix_filename): Adjust prototype.
1983 * w32.h (dostounix_filename): Adjust prototype.
1985 * msdos.c (dostounix_filename): Accept an additional argument and
1987 (init_environment): Adjust callers of dostounix_filename.
1989 * fileio.c (Ffile_name_directory, file_name_as_directory)
1990 (directory_file_name, Fexpand_file_name)
1991 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1993 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1995 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1996 variables, as egetenv is case-insensitive for DOS_NT.
1998 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1999 with an encoded file name.
2001 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
2002 Adjust calls to dostounix_filename.
2004 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
2006 * unexw32.c (unexec): Adjust call to dostounix_filename.
2008 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
2010 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
2013 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
2016 * callproc.c (Fcall_process): Make sure program name in PATH and
2017 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
2018 is passed to exec/spawnve, which fails unless the file-name
2021 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
2022 even if w32-quote-process-args is nil.
2024 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2026 Fix timestamp bug when write-region appends nothing (Bug#13149).
2027 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
2028 the file's time stamp doesn't change if Emacs happens to write nothing
2029 to the file, and on a buggy file system this could cause Emacs to
2030 incorrectly infer that the file system doesn't have the bug.
2031 Avoid this problem by inhibiting the inference in this case.
2033 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
2035 * window.h (struct window): Convert base_line_number, base_line_pos
2036 and column_number_displayed members from Lisp_Object to ptrdiff_t.
2037 Convert region_showing member from Lisp_Object to bitfield.

2040 (make_window): Initialize column_number_displayed.
2041 * print.c (print_object): Follow the printed representation of
2042 frames and print window pointer to distinguish between windows.

2044 * xdisp.c (wset_base_line_number, wset_base_line_pos)
2045 (wset_column_number_displayed, wset_region_showing): Remove.
2046 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
2047 (try_scrolling, try_cursor_movement, redisplay_window)
2048 (try_window_reusing_current_matrix, try_window_id, display_line)
2049 (display_mode_lines, decode_mode_spec): Adjust users.
2050 * .gdbinit (pwinx): Do not print sequence_number.
2052 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
2054 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
2055 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
2056 * dired.c: Include <fcntl.h>.
2057 (open_directory): New function, which uses open and fdopendir
2058 rather than opendir. DOS_NT platforms still use opendir, though.
2059 (directory_files_internal, file_name_completion): Use it.
2060 (file_attributes): New function, with most of the old Ffile_attributes.
2061 (directory_files_internal, Ffile_attributes): Use it.
2062 (file_attributes, file_name_completion_stat): First arg is now fd,
2063 not dir name. All uses changed. Use fstatat rather than lstat +
2065 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
2066 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
2067 (emacs_readlinkat): New function, with much of the old
2068 Ffile_symlink_p, but with an fd argument for speed.
2069 It uses readlinkat rather than careadlinkatcwd, so that it
2070 need not assume the working directory.
2071 (Ffile_symlink_p): Use it.
2072 * filelock.c (current_lock_owner): Use emacs_readlinkat
2073 rather than emacs_readlink.
2074 * lisp.h (emacs_readlinkat): New decl.
2075 (READLINK_BUFSIZE, emacs_readlink): Remove.
2076 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2077 (emacs_norealloc_allocator, emacs_readlink): Remove.
2078 This stuff is moved to fileio.c.
2079 * w32.c (fstatat, readlinkat): New functions.
2080 (careadlinkat): Don't check that fd == AT_FDCWD.
2081 (careadlinkatcwd): Remove; no longer needed.
2083 2013-01-31 Glenn Morris <rgm@gnu.org>
2085 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2086 (Fwrite_region): Update for new choose_write_coding_system args.
2087 Move the last piece of choose_write_coding_system here. (Bug#13522)
2088 (syms_of_fileio): Add choose-write-coding-system.
2090 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2092 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2093 (sys_close): Zero out the flags for the file descriptor before
2094 closing it. (Bug#13546)
2096 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2097 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2098 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2101 * w32.c (w32_get_long_filename, init_environment, readlink):
2102 Support file names encoded in DBCS codepages.
2103 (readlink): Use the current file-name-coding-system, not the ANSI
2104 codepage, to decode and handle targets of symlinks.
2106 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2108 * w32.c (opendir): Now accepts a 'const char *'.
2110 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2112 Remove obsolete redisplay code. See the discussion at
2113 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2114 * dispnew.c (preemption_period, preemption_next_check): Remove.
2115 (Vredisplay_preemption_period): Likewise.
2116 (update_frame, update_single_window, update_window, update_frame_1):
2117 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2118 used, following the 2012-06-22 change.
2120 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2122 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2124 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2126 * font.c (num_fonts): Remove the leftover from old
2127 debugging code. Adjust comment style here and there.
2128 * insdel.c (insert_1): Remove.
2129 * lisp.h (insert_1): Remove prototype.
2130 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2132 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2134 * w32.c (max_filename_mbslen): New function.
2135 (normalize_filename, readdir): Use it to detect locales where ANSI
2136 encoding of file names uses a double-byte character set (DBCS).
2137 If a DBCS encoding is used, advance by characters using
2138 CharNextExA, instead of incrementing a 'char *' pointer.
2139 Use _mbslwr instead of _strlwr. (Bug#13515)
2141 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2142 request of memory reservation to 1.7GB. (Bug#13065)
2144 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2146 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2147 at check_extra_latin label. (Bug#13505)
2149 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2151 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2152 Avoid redundant calls to strlen.
2154 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2156 Drop async_visible and async_iconified fields of struct frame.
2157 This is possible because async input is gone; for details, see
2158 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2159 * frame.h (struct frame): Remove async_visible and async_iconified
2160 members, convert garbaged to unsigned bitfield. Adjust comments.
2161 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2162 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2163 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2164 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2165 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2167 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2168 properly. Likewise for obscured.
2170 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2173 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2175 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2177 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2178 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2180 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2182 * xdisp.c (message2, message2_nolog): Remove functions.
2183 (message3, message3_nolog): Extract nbytes and multibyteness directly
2184 from the string. Change all callers.
2185 (message3_nolog): Don't set message_enable_multibyte since set_message
2186 will reset it anyway.
2187 (message1, message1_nolog): Use message3.
2188 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2189 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2190 (set_message): Drop all but the second arg, which has to be a string.
2191 (set_message_1): Simplify now that we know that a1 is NULL and the
2192 second arg is a string.
2193 * frame.h (struct frame): Remove `message_buf' field.
2194 Use glyphs_initialized_p instead.
2195 (FRAME_MESSAGE_BUF): Remove macro.

2197 * lisp.h (message2, message2_nolog): Remove declarations.
2198 (message3, message3_nolog): Update declarations.
2199 * keyboard.c (read_char_minibuf_menu_text)
2200 (read_char_minibuf_menu_width): Remove vars.
2201 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2202 to correctly handle multibyte strings.
2203 * frame.c (delete_frame): Don't free message_buf any more.
2204 * editfns.c (message_text, message_length): Remove vars.
2205 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2206 * fileio.c (auto_save_error): Use message3 instead of message2.
2207 * dispnew.c (adjust_frame_message_buffer): Remove function.
2209 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2211 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2212 real estate used for the tool bar and the menu bar.
2214 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2216 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2217 hidden buffer is prepared to modification (Bug#13164).
2219 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2221 * window.h (struct window): Change window_end_valid member from
2222 Lisp_Object to a bitfield. Adjust comments.
2223 (wset_window_end_valid): Remove.
2224 * window.c (adjust_window_count): Clear window_end_valid.
2225 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2226 (Fwindow_line_height, set_window_buffer, Frecenter)
2227 (Fsplit_window_internal, Fdelete_other_windows_internal)
2228 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2229 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2230 * xdisp.c (check_window_end, reconsider_clip_changes)
2231 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2232 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2233 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2235 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2237 * xdisp.c (mark_window_display_accurate): Simplify the loop
2238 assuming that the only one of vchild, hchild or buffer window
2239 slots is non-nil. Call mark_window_display_accurate_1 for
2240 the leaf windows only.
2241 (mark_window_display_accurate_1): Always assume leaf window.
2244 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2246 * emacs.c (Qkill_emacs_hook): Now static.
2248 * fileio.c (Finsert_file_contents): Simplify.
2249 Remove unnecessary assignments and tests.
2251 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2253 * w32.c (acl_set_file): Don't test for errors unless
2254 set_file_security returns FALSE. Avoids spurious errors when
2257 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2259 * fileio.c (Finsert_file_contents): Revert code introduced at
2260 2013-01-18 in favor of the simpler and generally better fix.
2261 Save stack space by removing 'buffer' and reusing 'read_buf'
2264 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2266 * lisp.h (eabs): Define unconditionally (Bug#13419).
2267 The old "#if !defined (eabs)" was an unnecessary revenant of back
2268 when this macro was called "abs". Document 'eabs' better.
2270 2013-01-19 Glenn Morris <rgm@gnu.org>
2272 * fns.c (Frandom): Doc fix.
2274 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2276 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2277 segfault when there are lots of overlays.
2279 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2280 when there are lots of overlays.
2281 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2282 for the details and a way to reproduce.
2284 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2286 * fileio.c: Use O_APPEND to append.
2287 This corresponds better to the natural interpretation of "append",
2288 and avoids the need to open the output file twice, or to invoke
2289 lseek when APPEND is neither nil nor a number.
2290 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2291 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2292 file possibly twice, and lseeking to its end; this avoids the
2293 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2294 at the same time: the combination is never needed and apparently
2295 it doesn't work with DOS_NT.
2297 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2298 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2300 Allow floating-point file offsets.
2301 Problem reported by Vitalie Spinu in
2302 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2303 * fileio.c (emacs_lseek): Remove.
2304 (file_offset): New function.
2305 (Finsert_file_contents, Fwrite_region): Use it.
2307 2013-01-19 Chong Yidong <cyd@gnu.org>
2309 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2310 aborting on Fsignal (Bug#13289).
2312 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2314 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2315 set_file_security as failure due to insufficient privileges.
2316 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.

2319 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2321 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2322 The bug was observed on Ubuntu operating inside a virtual machine,
2323 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2324 The workaround introduces a race condition on non-buggy hosts,
2325 but it's an unlikely race and anyway there's a nearly identical
2326 nearby race that can't be fixed.
2327 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2329 (Fwrite_region): Test for file system time stamp bug.
2330 (init_fileio): New function.

2346 gap and end positions after each read and so help make_gap to work
2347 properly. Do not signal an I/O error too early and so do not leave
2348 not yet decoded characters in a buffer, which was the reason of
2349 redisplay crash. Use list2 to build return value. Adjust comments.
2351 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2353 Close a race when statting and reading files (Bug#13149).
2354 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2355 This avoids a race if the file is renamed between stat and open.

2778 * window.c (select_window_1): Now static, since it's used only here.
2780 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2782 * window.c (window_body_cols): Subtract display margins from the
2783 window body width on TTYs as well. See
2784 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2785 for the original report.
2787 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2789 * xdisp.c (redisplay_window): Remove inner local variable
2790 because the outer shadowed one has the same meaning.
2791 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2793 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2794 (xg_create_tool_bar): Adjust users.
2796 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2798 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2799 * buffer.c (Fget_buffer_create): Use it to set compact field of
2800 struct buffer_text to avoid accessing an uninitialized value
2801 when compact_buffer is called for the first time.
2802 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2803 (Fset_buffer_modified_p): Use buffer_window_count to check
2804 whether the buffer is displayed in some window.
2805 * xdisp.c (message_dolog): Likewise.
2807 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2809 * w32.c (acl_set_file): If setting the file security descriptor
2810 fails, and the new DACL is identical to the existing one, silently
2811 return success. This fixes problems for users backing up their
2812 own files without having the necessary privileges for setting
2813 security descriptors.
2815 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2817 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2818 after WaitForSingleObject returns normally. This expedites reader
2819 thread shutdown when delete_child triggers it.
2820 (reap_subprocess): More accurate commentary for why we call
2821 delete_child only when cp->fd is negative.
2823 * w32.c (sys_close): Do not call delete_child on a subprocess
2824 whose handle is not yet closed. Instead, set its file descriptor
2825 to a negative value, so that reap_subprocess will call
2826 delete_child on that subprocess when its SIGCHLD arrives.
2827 This avoids closing handles used for communications between sys_select
2828 and reader_thread, which doesn't give sys_select a chance to
2829 notice that the process exited and invoke the SIGCHLD handler for
2832 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2834 * nsfns.m (Fns_do_applescript): Run event loop until script has
2835 been executed (Bug#12969).
2836 (ns_run_ascript): Chech as_script for nil, set to nil after
2839 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2841 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2843 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2845 * w32term.c (w32fullscreen_hook): New function.
2846 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2848 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2850 * fileio.c (Finsert_file_contents): Doc fix.
2852 * w32proc.c (new_child, delete_child, find_child_pid): For a
2853 subprocess, consider its slot being in use as long as its process
2854 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2855 slot when a new process is started immediately after killing
2856 another one, without waiting enough time for the first process to
2857 be reaped and resources allocated for it be orderly freed.
2859 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2861 2012-12-21 Chong Yidong <cyd@gnu.org>
2863 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2865 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2867 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2869 * w32.c (get_name_and_id): Always pass NULL as the first argument
2870 of lookup_account_sid. Avoids crashes with UNC file names that
2871 refer to DFS domains, not to specific machine names. (Bug#12621)
2872 Remove now unused argument FNAME; all callers changed.
2873 (get_file_owner_and_group): Remove now unused argument FNAME; all
2876 2012-12-21 Chong Yidong <cyd@gnu.org>
2878 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2879 error for invalid chars, don't check for a nil return value.
2881 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2883 Avoid calls to CHAR_TO_BYTE if byte position is known.
2884 * editfns.c (make_buffer_string_both): Use move_gap_both.
2885 (Fbuffer_string): Use make_buffer_string_both.
2886 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2888 (buf_bytepos_to_charpos): Likewise.
2889 (charpos_to_bytepos): Remove.
2890 * fileio.c (Finsert_file_contents): Use move_gap_both.
2891 * search.c (Freplace_match): Likewise.
2892 * process.c (process_send_region): Likewise. Use convenient
2893 names for byte positions.
2894 * lisp.h (charpos_to_bytepos): Remove prototype.
2895 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2896 * insdel.c (move_gap): Likewise.
2898 2012-12-20 Paul Eggert <eggert@cs.ucla.edu>
2900 * xdisp.c (redisplay_internal): Remove now-unused local.
2902 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2904 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2905 (redisplay_internal): Don't bother selecting the frame to get the
2906 proper value of frame-local variables (bug#13225).
2908 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2910 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2911 Rename 4th argument since it may be buffer or string. Adjust comment.
2912 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2914 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2916 * coding.c (Fdetect_coding_region): Do not check start and end with
2917 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2918 (code_convert_region): Likewise.
2920 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2922 * w32.c (acl_get_file, acl_set_file): Run the file name through
2923 map_w32_filename, and resolve any symlinks in the file name, like
2925 (acl_set_file): Call revert_to_self, if any privileges were
2928 2012-12-17 Juanma Barranquero <lekktu@gmail.com>
2930 * makefile.w32-in ($(BLD)/editfns.$(O), $(BLD)/fileio.$(O))
2931 ($(BLD)/w32.$(O)): Update dependencies.
2933 2012-12-17 Stefan Monnier <monnier@iro.umontreal.ca>
2935 * xdisp.c (select_frame_for_redisplay): Use select_window_1 to
2936 propagate redisplay's scrolling (if any) to the right window.
2937 (redisplay_internal): Use ensure_selected_frame.
2938 (display_mode_lines): Complete last fix.
2939 * window.c (select_window_1): New func, extracted from select_window.
2940 (select_window): Use it.
2941 * window.h (select_window_1): Declare.
2943 2012-12-17 Eli Zaretskii <eliz@gnu.org>
2945 Emulate Posix ACL APIs on MS-Windows.
2946 * w32.c: Include sddl.h and sys/acl.h.
2947 (SDDL_REVISION_1): Define if not already defined.
2948 (g_b_init_get_security_descriptor_dacl)
2949 (g_b_init_convert_sd_to_sddl, g_b_init_convert_sddl_to_sd)
2950 (g_b_init_is_valid_security_descriptor)
2951 (g_b_init_set_file_security): New static flags.

2963 (acl_free, acl_get_file, acl_set_file): New functions.
2965 * fileio.c (Fcopy_file) [WINDOWSNT]: Support copying ACLs.
2967 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2969 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2970 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2971 for some of that bug's symptoms can now cause Emacs to abort.
2972 Remove the workaround.
2973 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2974 The bug that caused SIGCHLD to get lost has been fixed, and the
2975 workaround for it can now cause Emacs to abort.
2977 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2979 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2980 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2981 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.
2983 2012-12-16 Romain Francoise <romain@orebokech.com>
2985 * fileio.c (Ffile_acl, Fset_file_acl): New functions.
2986 (Fcopy_file): Change last arg to `preserve_extended_attributes'
2987 and copy ACL entries of file in addition to SELinux context if set.
2988 (syms_of_fileio): Add `file-acl' and `set-file-acl'.
2990 * Makefile.in (LIBACL_LIBS): New macro.
2993 2012-12-15 Paul Eggert <eggert@cs.ucla.edu>
2995 * fileio.c (internal_delete_file): Use bool for boolean.
2997 2012-12-15 Eli Zaretskii <eliz@gnu.org>
2999 Fix bug #13079 on MS-Windows with temp files not being deleted.

3002 (register_child): First argument is now pid_t.
3003 (record_infile, record_pending_deletion): New prototypes.
3005 * w32proc.c (new_child): Initialize input_file and
3006 pending_deletion members of the child.
3007 (delete_child): Delete the child's temporary input file, if any,
3008 that is pending deletion.
3009 (register_child): First argument is now pid_t.
3010 (record_infile, record_pending_deletion): New functions.
3011 (reap_subprocess): Fix a typo in DebPrint string.
3012 (sys_spawnve, sys_kill): Use pid_t for PID arguments.
3014 * fileio.c (internal_delete_file): Return an int again: non-zero
3015 if delete-file succeeds, zero otherwise.
3017 * lisp.h (internal_delete_file): Adjust prototype.
3019 * callproc.c (Fcall_process): Don't overwrite infile with result
3021 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
3022 asynchronous subprocess, record the name of the input file name,
3024 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
3025 delete the file, record it as pending deletion when the subprocess
3028 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3030 * editfns.c [HAVE_PWD_H]: Include grp.h.
3032 * makefile.w32-in ($(BLD)/editfns.$(O)): Add $(NT_INC)/grp.h.
3034 2012-12-14 Paul Eggert <eggert@cs.ucla.edu>
3036 Fix permissions bugs with setgid directories etc. (Bug#13125)
3037 * dired.c (Ffile_attributes): Return t as the 9th attribute,
3038 to mark it as a placeholder. The old value was often wrong.
3039 The only user of this attribute has been changed to use
3040 file-ownership-preserved-p instead, with its new group arg.
3041 * editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
3043 2012-12-14 Stefan Monnier <monnier@iro.umontreal.ca>
3045 * xdisp.c (select_frame_for_redisplay, display_mode_lines):

3048 2012-12-14 Eli Zaretskii <eliz@gnu.org>
3050 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
3051 try to get accurate owner and group information from NT file
3052 security APIs. This is to make most callers of 'stat' and
3053 'lstat', which don't need that information, much faster.
3055 * dired.c (Ffile_attributes) [WINDOWSNT]:
3056 Set w32_stat_get_owner_group to a non-zero value, to request accurate
3057 owner and group information from 'lstat'.
3059 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3061 * fileio.c (Finsert_file_contents): Don't put tail into head area,
3062 as that confuses set-auto-coding, so insist on the head-read
3063 returning the full 1024 bytes. Let lseek compute the tail offset;
3064 less work for us. Do not ignore I/O errors when reading the tail.
3066 * xdisp.c: Minor style fixes.
3067 (init_iterator): Hoist assignment out of if-expression.
3068 (markpos_of_region): Callers now test for sign, not for -1.
3070 2012-12-13 Dmitry Antipov <dmantipov@yandex.ru>
3072 Minor redisplay optimization when the region length is zero.
3073 * xdisp.c (markpos_of_region): New function.
3074 (init_iterator): Do not highlight the region of zero length.
3075 (redisplay_window): Check whether the region is of non-zero length.
3076 (try_cursor_movement): Allow if the region length is zero.
3077 (try_window_reusing_current_matrix, try_window_id): Likewise.
3079 2012-12-13 Eli Zaretskii <eliz@gnu.org>
3081 * search.c (search_buffer): Check the inverse translations of each
3082 character in pattern when the buffer being searched is unibyte.
3085 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3087 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3088 files, fixing a regression from 24.2.
3089 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3091 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3093 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3094 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3095 Remove unnecessary S_ISLNK test, as (contra the comments) this
3096 function can't copy symlinks. Improve quality of error message
3097 when attempting to copy files that are neither regular files nor

3105 * xdisp.c (resize_mini_window, hscroll_window_tree, draw_glyphs):
3106 * xterm.c (x_set_toolkit_scroll_bar_thumb): Likewise.
3108 2012-12-12 Daniel Colascione <dancol@dancol.org>
3110 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
3111 the dumped Emacs is not a sparse file, greatly improving Cygwin
3112 "make bootstrap" performance.
3114 2012-12-11 Michael Albinus <michael.albinus@gmx.de>
3116 * inotify.c (inotify_callback): Generate an Emacs event for every
3117 incoming inotify event.
3119 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3121 * xdisp.c (handle_face_prop): Fix logic of computing
3122 it->start_of_box_run_p.
3123 (append_space_for_newline): If the glyph row is R2L, reset the
3124 iterator's end_of_box_run_p flag before prepending the space glyph.
3125 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3126 iterator's start_of_box_run_p flag before prepending the stretch.
3127 (append_glyph, produce_image_glyph, append_composite_glyph)
3128 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3129 left_box_line_p and right_box_line_p flags of the glyph for R2L
3130 glyph rows. (Bug#13011)
3132 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3134 * buffer.c (Fset_buffer_multibyte): Do not force redisplay
3135 if changed buffer is not shown in a window.
3136 * insdel.c (prepare_to_modify_buffer): Likewise.
3137 * window.c (replace_buffer_in_windows_safely): Do nothing
3138 if buffer is not shown in a window.

3144 * inotify.c (Finotify_add_watch): Rename decoded_file_name to
3145 encoded_file_name, which is what it is.
3147 2012-12-11 Dmitry Antipov <dmantipov@yandex.ru>
3149 Consistently use marker_position and marker_byte_position.
3150 * fringe.c (Ffringe_bitmaps_at_pos):

3158 (mark_window_display_accurate_1, redisplay_window, decode_mode_spec):
3159 Replace direct access to marker fields with calls
3160 to marker_position and/or marker_byte_position.
3162 2012-12-11 Juanma Barranquero <lekktu@gmail.com>
3164 * makefile.w32-in (SIG2STR_H): New macro.

3171 Windows file notification functionality unless WINDOWSNT.
3173 * w32gui.h (hprevinst, lpCmdLine, nCmdShow): Remove unused
3176 * w32fns.c (cache_system_info): Initialize the global hinst
3177 variable here so various initialization calls DTRT.
3179 * unexw32.c (hprevinst, lpCmdLine, nCmdShow): Remove unused variables.
3180 (hinst): Remove unneeded extern declaration.
3181 (_start): Remove initialization of above variables; remove
3182 initialization of hinst, as cache_system_info now does that.
3184 * emacs.c (main): Call cache_system_info early in startup; we
3185 previously weren't calling it in Cygwin builds.
3187 * Makefile.in (ntsource, WINDRES, W32_RES, W#@_RES_LINK):
3188 Teach the autoconf build system how to compile a Windows resource file
3189 and link it to Emacs.

3291 * nsterm.m (fd_handler:): FD_ZERO fds (Bug#13103).
3293 2012-12-10 Fabrice Popineau <fabrice.popineau@gmail.com>
3295 * w32fns.c (cache_system_info): Cast sysinfo_cache.dwPageSize to
3296 DWORD_PTR, for compatibility with 64-bit builds.
3298 * w32.c (_PROCESS_MEMORY_COUNTERS_EX):
3299 (GetProcessWorkingSetSize_Proc, get_process_working_set_size)

3310 displayed on the left or the right margin, don't consider it as a
3311 factor in cursor positioning. (Bug#13108)

3322 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3324 * w32.c (unsetenv): Return 0 if the input string is too long.
3326 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3328 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
3329 * alloc.c (xputenv): New function.
3330 * dbusbind.c (Fdbus_init_bus):
3332 * xterm.c (x_term_init):
3333 Use xputenv instead of setenv or putenv, to detect memory exhaustion.

3336 (init_editfns): Initialize these two static vars.
3337 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
3338 Save old TZ value on stack, if it's small.
3339 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
3340 instead, use xputenv+unsetenv to set and restore TZ.
3341 (environbuf): Remove static var. All uses removed.
3342 (Fset_time_zone_rule): Do not save TZ and environ;
3343 no longer needed here.
3344 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3345 Move to inside set_time_zone_rule; they don't need file scope any more.
3346 (set_time_zone_rule): Maintain the TZ=value string separately.
3347 (syms_of_editfns): Don't initialize initial_tz;
3348 init_editfns now does it.
3349 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3350 * lisp.h (xputenv): New decl.
3352 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
3354 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
3356 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3358 * w32.c (unsetenv, sys_putenv): New functions.
3360 2012-12-08 Chong Yidong <cyd@gnu.org>

3363 informative (Bug#12992).
3365 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3367 Simplify get_lim_data.
3368 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3369 Remove USG and vlimit methods; no longer used these days.
3370 Add #error catchall just in case.
3372 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3373 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3374 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3375 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
3376 (deleted_pid_list, Fdelete_process, create_process)
3377 (record_child_status_change, handle_child_signal, deliver_child_signal)
3378 (init_process_emacs, syms_of_process):
3379 Assume SIGCHLD is defined.
3380 (parse_signal): Remove. All uses removed.
3381 (abbr_to_signal): New static function.
3382 (Fsignal_process): Use it to convert signal names to ints.
3383 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
3384 kill (getpgrp (), ...).
3385 (emacs_sigaction_init): Assume SIGCHLD is defined.
3386 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
3387 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.

3389 All uses replaced by 'kill' with a negative pid.
3390 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
3391 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
3393 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3395 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3396 This will cause a production Emacs to dump core instead of
3399 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3401 * frame.c (make_frame): Do not set window's buffer to t.
3402 * window.c (Fsplit_window_internal): Likewise. Previously it was
3403 used to indicate that the window is being set up. Now we use
3404 set_window_buffer for all new windows, so the condition in ...
3405 (Fset_window_buffer): ... is always true and can be removed.
3407 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3409 Convenient macro to check whether the buffer is hidden.
3410 * buffer.h (BUFFER_HIDDEN_P): New macro.
3411 * frame.c (make_frame): Use it. Adjust comment.
3412 * buffer.c (candidate_buffer): New function.
3413 (Fother_buffer, other_buffer_safely): Use it.
3415 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3417 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3418 if the child process is still running. Instead, exit the wait
3419 loop and return zero. (Bug#13086)
3421 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3423 * frame.h (x_char_width, x_char_height): Remove prototypes.
3424 * w32term.h (x_char_width, x_char_height): Likewise.

3437 * callproc.c, process.h (record_kill_process):
3438 New function, containing part of the old call_process_kill.
3439 (call_process_kill): Use it.
3440 This does not change call_process_kill's behavior.
3441 * process.c (Fdelete_process): Use record_kill_process to fix a
3442 race condition that could cause Emacs to lose track of a child.
3444 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3446 Avoid code duplication between prev_frame and next_frame.
3447 * frame.c (candidate_frame): New function. Add comment.
3448 (prev_frame, next_frame): Use it. Adjust comment.
3450 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3452 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3453 fails, signal an error instead of continuing with an empty
3455 Encode expanded temp file pattern before passing it to mkstemp or
3458 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3459 Encode the file name before passing it to dostounix_filename, in
3460 case it will downcase it (under w32-downcase-file-names).
3463 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3465 Minor call-process cleanups.
3466 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3467 at the same time as other platforms, to simplify analysis.
3468 No need for fd0_volatile since we have synch_process_fd.
3469 Avoid needless emacs_close; arg is always negative.
3471 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3473 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3476 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3478 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3479 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3480 and mouse_face_hidden members to a bitfields.
3481 * frame.h (struct frame): Remove set-but-not-used space_width member.
3482 (FRAME_SPACE_WIDTH): Remove.
3483 * nsterm.m, w32term.c, xterm.c: Adjust users.
3484 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3485 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3486 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3487 members to a bitfields.
3489 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3491 Don't let call-process be a zombie factory (Bug#12980).
3492 Fixing this bug required some cleanup of the signal-handling code.
3493 As a side effect, this change also fixes a longstanding rare race
3494 condition whereby Emacs could mistakenly kill unrelated processes,
3495 and it fixes a bug where a second C-g does not kill a recalcitrant
3496 synchronous process in GNU/Linux and similar platforms.
3497 The patch should also fix the last vestiges of Bug#9488,
3498 a bug which has mostly been fixed on the trunk by other changes.
3499 * callproc.c, process.h (synch_process_alive, synch_process_death)
3500 (synch_process_termsig, sync_process_retcode):
3501 Remove. All uses removed, to simplify analysis and so that
3502 less consing is done inside critical sections.
3503 * callproc.c (call_process_exited): Remove. All uses replaced
3504 with !synch_process_pid.
3505 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3506 These take the role of what used to be in unwind-protect arg.
3508 (block_child_signal, unblock_child_signal):
3509 New functions, to avoid races that could kill innocent-victim processes.
3510 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3511 (call_process_kill): Record killed processes as deleted, so that
3512 zombies do not clutter up the system. Do this inside a critical
3513 section, to avoid a race that would allow the clutter.
3514 (call_process_cleanup): Fix code so that the second C-g works again
3515 on common platforms such as GNU/Linux.
3516 (Fcall_process): Create the child process in a critical section,
3517 to fix a race condition. If creating an asynchronous process,
3518 record it as deleted so that zombies do not clutter up the system.
3519 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3520 light of these changes. Omit unnecessary call to emacs_close
3521 before failure, as the unwind-protect code does that.
3522 * callproc.c (call_process_cleanup):
3523 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3524 * process.c (record_deleted_pid): New function, containing
3525 code refactored out of Fdelete_process.
3526 (Fdelete_process): Use it.
3527 (process_status_retrieved): Remove. All callers changed to use
3528 child_status_change.
3529 (record_child_status_change): Remove, folding its contents into ...
3530 (handle_child_signal): ... this signal handler. Now, this
3531 function is purely a handler for SIGCHLD, and is not called after
3532 a synchronous waitpid returns; the synchronous code is moved to
3533 wait_for_termination. There is no need to worry about reaping
3534 more than one child now.
3535 * sysdep.c (get_child_status, child_status_changed): New functions.
3536 (wait_for_termination): Now takes int * status and bool
3537 interruptible arguments, too. Do not record child status change;
3538 that's now the caller's responsibility. All callers changed.
3539 Reimplement in terms of get_child_status.
3540 (wait_for_termination_1, interruptible_wait_for_termination):
3541 Remove. All callers changed to use wait_for_termination.
3542 * syswait.h: Include <stdbool.h>, for bool.
3543 (record_child_status_change, interruptible_wait_for_termination):
3545 (record_deleted_pid, child_status_changed): New decls.
3546 (wait_for_termination): Adjust to API changes noted above.
3548 * bytecode.c, lisp.h (Qbytecode): Remove.
3549 No longer needed after 2012-11-20 interactive-p changes.
3551 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3553 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3554 the scroll margin, move point outside the margin. (Bug#13055)
3556 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3558 * gtkutil.c (my_log_handler): New function.
3559 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3561 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3563 * lisp.h (modify_region): Rename to...
3564 (modify_region_1): ...new prototype.
3565 * textprop.c (modify_region): Now static. Adjust users.
3566 * insdel.c (modify_region): Rename to...
3567 (modify_region_1): ...new function to work with current buffer.
3568 Adjust comment and users. Use true and false for booleans.
3570 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3572 * alloc.c (free_save_value): New function.
3573 (safe_alloca_unwind): Use it.
3574 * lisp.h (free_save_value): New prototype.
3575 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3577 (save_excursion_restore): Adjust to match saved data structure.
3578 Use free_save_value to offload some work from GC. Drop obsolete
3581 2012-12-03 Chong Yidong <cyd@gnu.org>
3583 * fileio.c (Vauto_save_list_file_name): Doc fix.
3585 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3587 * w32fns.c: Remove prototype of atof.
3588 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3590 (file_dialog_callback): Make it UINT_PTR.
3592 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3595 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3596 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3599 2012-12-03 Glenn Morris <rgm@gnu.org>
3601 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3603 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3605 Fix xpalloc confusion after memory is exhausted.
3606 * alloc.c (xpalloc): Comment fix.
3607 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3608 and signals an error, do not clear charset_table_size, as
3609 charset_table is still valid.
3610 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3612 Use execve to avoid need to munge environ (Bug#13054).
3613 * callproc.c (Fcall_process):
3614 * process.c (create_process):
3615 Don't save and restore environ; no longer needed.
3616 * callproc.c (child_setup):
3617 Use execve, not execvp, to preserve environ.
3619 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3621 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3623 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3625 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3626 display for sliced images (Bug#10500).
3628 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3630 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3632 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3633 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3635 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3637 * xdisp.c (window_outdated): Remove eassert since it hits
3638 some suspicious corner cases (see Bug#13007 and Bug#13012).
3639 (mode_line_update_needed): New function.
3640 (redisplay_internal, redisplay_window): Use it.
3641 (ensure_selected_frame): New function.
3642 (redisplay_internal, unwind_redisplay): Use it.
3643 (redisplay_internal): Move comment about buffer_shared...
3644 (buffer_shared_and_changed): ...near to its real use.
3646 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3648 * callproc.c (Fcall_process): Don't misreport vfork failure.
3650 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3652 * callproc.c (Fcall_process): Fix vfork portability problems.
3653 Do not assume that fd[0], count, filefd, and save_environ survive
3654 vfork. Fix bug whereby wrong errno value could be reported for
3655 pipe failure. Some minor cleanups, too, as follows. Move buf and
3656 bufsize to the context where they're needed. Change new_argv to
3657 be of type char **, as this is more convenient and avoids casts.
3658 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3659 Now local constants, not macros.
3661 2012-11-18 Kenichi Handa <handa@gnu.org>
3663 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3664 for the variable "f".
3666 2012-11-13 Kenichi Handa <handa@gnu.org>
3668 * font.c (font_unparse_xlfd): Exclude special characters from the
3669 generating XLFD name.
3671 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3673 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.
3674 * dired.c (stat_uname, stat_gname):
3675 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
3677 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).
3678 * dired.c (directory_files_internal, file_name_completion):
3679 Assume EAGAIN and EINTR are defined.
3681 * fileio.c (Fcopy_file): Assume EISDIR is defined.
3682 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
3683 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
3684 * lread.c (readbyte_from_file): Assume EINTR is defined.
3685 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3686 Assume EIO and EAGAIN are defined.
3687 * unexcoff.c (write_segment): Assume EFAULT is defined.
3689 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3691 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3694 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3695 highlighting on the frame was cleared. Prevents assertion
3696 violations when repeatedly clicking on the "Top" link of the
3697 "bread-crumbs" in Info buffers.
3699 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
3701 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
3703 2012-11-24 Ken Brown <kbrown@cornell.edu>
3705 * keyboard.c (HAVE_MOUSE):
3706 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3707 were always defined.
3709 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3711 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3712 between bpos_covered and bpos_max. This fixes cursor display when
3713 several display strings follow each other.
3715 * .gdbinit (pgx): If the glyph's object is a string, display the
3716 pointer to string data, rather than the value of the string object
3717 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3719 * indent.c (Fvertical_motion): If the starting position is covered
3720 by a display string, return to one position before that, to avoid
3721 overshooting it inside move_it_to. (Bug#12930)
3723 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3725 * frame.h (struct frame): Remove display_preempted member
3726 since all users are dead long ago.
3727 * nsterm.h (struct x_output): Use the only dummy member.
3728 * w32menu.c (pending_menu_activation): Remove since not
3730 (set_frame_menubar): Adjust user.
3731 * w32term.h (struct x_output): Drop outdated #if 0 code.
3732 (struct w32_output): Use bitfields for explicit_parent,
3733 asked_for_visible and menubar_active members.
3734 Drop unused pending_menu_activation member.
3735 * xterm.h (struct x_output): Drop outdated #if 0 code.
3736 Use bitfields for explicit_parent, asked_for_visible,
3737 has_been_visible and net_wm_state_hidden_seen members.
3739 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3741 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3742 of a literal "/". (Bug#12955)
3743 (gl-stamp): Invoke fc.exe directly, not through cmd.
3745 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3747 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3748 * dired.c: Assume HAVE_DIRENT_H.
3749 (NAMLEN): Remove, replacing with ...
3750 (dirent_namelen): New function. All uses changed. Use the GNU macro
3751 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3752 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3753 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3754 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3756 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3757 * ndir.h: Rename to ../nt/inc/dirent.h.
3758 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3759 Do not include <dirent.h>; no longer needed.
3760 * w32.c: Include <dirent.h> rather than "ndir.h".
3762 2012-11-23 Chong Yidong <cyd@gnu.org>
3764 * xftfont.c (xftfont_open): Remove duplicate assignment.
3766 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3768 * alloc.c (Fgarbage_collect): Unblock input after clearing
3769 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3770 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3771 * msdos.c (IT_frame_up_to_date): Use it here...
3772 * w32term.c (w32_frame_up_to_date): ...here...
3773 * xterm.c (XTframe_up_to_date): ...and here...
3774 * nsterm.m (ns_frame_up_to_date): ...but not here.
3775 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3777 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3778 Do not check whether GC is in progress.
3780 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3782 * xdisp.c (window_buffer_changed): New function.
3783 (update_menu_bar, update_tool_bar): Use it to
3784 simplify large 'if' statements.
3785 (redisplay_internal): Generalize commonly used
3786 'tail' and 'frame' local variables.
3788 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3790 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3791 with Windows system header.
3793 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3795 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3796 * alloc.c: Assume unistd.h exists.
3797 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3798 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3799 (getwd) [USG]: Remove; no longer needed.
3800 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3801 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3802 * w32.h (getcwd): Remove decl.
3804 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3806 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3807 Make it set selected_window as well.
3808 (update_tool_bar): Use it.
3810 2012-11-21 Ken Brown <kbrown@cornell.edu>
3812 * emacs.c (main): Set the G_SLICE environment variable for all
3813 Cygwin builds, not just GTK builds. See
3814 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3816 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3818 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3819 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3820 Define for the MSVC compiler.
3822 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3824 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3825 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3826 dostounix_filename. Prevents crashes down the road, because
3827 dostounix_filename assumes it gets a unibyte string.
3828 Reported by Michel de Ruiter <michel@sentient.nl>, see
3829 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3831 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

3835 * lread.c (init_obarray): Set `function' fields to Qnil.
3836 * eval.c (Fcommandp): Ignore Qunbound.
3837 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3838 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3839 Test NILP rather than Qunbound.
3840 (Ffmakunbound): Set to Qnil.
3841 (Fsymbol_function): Never signal an error.
3842 (Finteractive_form): Ignore Qunbound.
3844 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3846 * eval.c (interactive_p): Remove no-longer-used decl.
3848 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3850 * xdisp.c (buffer_shared): Adjust comment.
3851 (buffer_shared_and_changed): New function.
3852 (prepare_menu_bars, redisplay_internal): Use it to
3853 decide whether all windows or frames should be updated.
3854 (window_outdated): New function.
3855 (text_outside_line_unchanged_p, redisplay_window): Use it.
3856 (redisplay_internal): Likewise. Fix indentation.
3858 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3860 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3861 (syms_of_eval): Remove corresponding defsubr.
3862 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3864 2012-11-19 Daniel Colascione <dancol@dancol.org>
3866 * w32fns.c (Fx_file_dialog):
3867 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3868 cygwin_convert_file_name*.
3870 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3871 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3873 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3875 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3877 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3879 * w32select.c: Include w32common.h before w32term.h, so that
3880 windows.h gets included before w32term.h uses some of its
3881 features, see below.
3883 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3885 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3887 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3889 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3891 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3892 (ns_select): Return at once if events are held (Bug#12834).
3894 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3896 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3897 Needed following 2012-10-20 change. (Bug#12902)
3899 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3901 * w32proc.c (waitpid): Remove unused label get_result.
3903 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3905 * makefile.w32-in (SYSWAIT_H): New macro.
3906 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3907 ($(BLD)/sysdep.$(O)): Update dependencies.
3909 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3911 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3912 * callproc.c (relocate_fd): Assume F_DUPFD.
3913 * emacs.c, term.c (O_RDWR): Remove.
3914 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3915 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3916 * nsterm.m: Assume <fcntl.h> exists.
3917 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3918 (create_pty, Fmake_network_process, server_accept_connection)
3919 (wait_reading_process_output, init_process_emacs):
3921 (wait_reading_process_output): Put in a special case for WINDOWSNT
3922 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3923 It's not clear this is needed, but it's a more-conservative change.
3924 (create_process): Assume FD_CLOEXEC.
3925 (create_process, create_pty): Assume O_NOCTTY.
3926 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3927 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3928 Omit if not DOS_NT, since F_GETFL is not defined there.
3929 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3930 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3932 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3933 lack it, since gnulib guarantees this.
3934 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3936 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3938 * w32.c (faccessat): Pretend that directories have the execute bit
3939 set. Emacs expects that, e.g., in files.el:cd-absolute.
3941 * w32proc.c (create_child): Don't clip the PID of the child
3942 process to fit into an Emacs integer, as this is no longer a
3944 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3945 reaping only the process specified by PID argument, if that is
3946 positive. Use PID instead of dead_child to know which process to
3947 reap. Wait for the child to die only if WNOHANG is not in
3949 (sys_select): Don't set dead_child.
3951 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3952 as it is no longer needed.
3954 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3956 (record_child_status_change): Remove the setting of
3957 record_at_most_one_child for the !WNOHANG case.
3959 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3961 Fix problems in ns port found by static checking.
3962 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3963 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3964 not to process group.
3965 (ns_select): Use emacs_write, not write, as that's more robust
3966 in the presence of signals.
3967 (fd_handler:): Check for read errors.
3969 2012-11-16 Glenn Morris <rgm@gnu.org>
3971 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3973 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3975 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3977 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3979 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3980 use the same value of thread handle.
3981 (start_timer_thread): If the timer thread exited (due to error),
3982 clean up by closing the two handles it used. Duplicate the caller
3983 thread's handle here, so it gets duplicated only once, when
3984 launching the timer thread. Set priority of the timer thread, not
3986 (getitimer): Don't duplicate the caller thread's handle here.
3989 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3991 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3994 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3996 Remove no-longer-used pty_max_bytes variable.
3997 * process.c (pty_max_bytes): Remove; unused.
3998 (send_process): Do not set it.
4000 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
4002 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
4003 Update dependencies.
4005 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
4007 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
4008 This follows up on the 2012-09-29 patch that removed indirection
4009 for the 'function' field. Reported by Sergey Vinokurov in
4010 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
4012 2012-11-14 Eli Zaretskii <eliz@gnu.org>
4014 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
4015 different name, as the MS runtime does not have such a function,
4016 and probably never will.) All callers changed. Ignore DIRFD
4017 value if PATH is an absolute file name, to match Posix spec
4018 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
4021 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
4023 * xdisp.c (echo_area_display, redisplay_internal):
4024 Omit redundant check whether frame_garbaged is set.
4026 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
4028 Use faccessat, not access, when checking file permissions (Bug#12632).
4029 This fixes a bug that has been present in Emacs since its creation.
4030 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
4031 which must set some sort of record. (Torek's bug report was against
4032 a predecessor of GNU Emacs, but GNU Emacs happened to have the
4033 same common flaw.) See Torek's Usenet posting
4034 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
4035 Posted: Fri Apr 8 14:18:56 1983.
4036 * Makefile.in (LIB_EACCESS): New macro.
4038 * callproc.c (init_callproc):
4039 * charset.c (init_charset):
4040 * fileio.c (check_existing, check_executable, check_writable)
4042 * lread.c (openp, load_path_check):
4043 * process.c (allocate_pty):
4045 Use effective UID when checking permissions, not real UID.
4046 * callproc.c (init_callproc):
4047 * charset.c (init_charset):
4048 * lread.c (load_path_check, init_lread):
4049 Test whether directories are accessible, not merely whether they exist.
4050 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
4051 * fileio.c (check_existing, check_executable, check_writable)
4053 Use symbolic names instead of integers for the flags, as they're
4055 (check_writable): New arg AMODE. All uses changed.
4056 Set errno on failure.
4057 (Ffile_readable_p): Use faccessat, not stat + open + close.
4058 (Ffile_writable_p): No need to call check_existing + check_writable.
4059 Just call check_writable and then look at errno. This saves a syscall.
4060 dir should never be nil; replace an unnecessary runtime check
4061 with an eassert. When checking the parent directory of a nonexistent
4062 file, check that the directory is searchable as well as writable, as
4063 we can't create files in unsearchable directories.
4064 (file_directory_p): New function, which uses 'stat' on most platforms
4065 but faccessat with D_OK (for efficiency) if WINDOWSNT.
4066 (Ffile_directory_p, Fset_file_times): Use it.
4067 (file_accessible_directory_p): New function, which uses a single
4068 syscall for efficiency.
4069 (Ffile_accessible_directory_p): Use it.
4070 * xrdb.c (file_p): Use file_directory_p.
4071 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
4072 * lread.c (openp): When opening a file, use fstat rather than
4073 stat, as that avoids a permissions race. When not opening a file,
4074 use file_directory_p rather than stat.
4075 (dir_warning): First arg is now a usage string, not a format.
4076 Use errno. All uses changed.
4077 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4078 that merely introduced a race.
4079 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4080 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4081 and similarly for the other O_* flags.
4082 * w32.c (sys_faccessat): Rename from sys_access and switch to
4083 faccessat's API. All uses changed.
4084 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4085 (magic_db): Rename from magic_file_p.
4086 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4087 char *, so that we don't have to test for file existence
4088 separately from opening the file for reading. This removes a race
4089 fixes a permission-checking problem, and simplifies the code.
4091 (file_p): Remove; no longer needed.
4093 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4095 Omit glyphs initialization at startup.
4096 * dispnew.c (glyphs_initialized_initially_p): Remove.
4097 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4098 (Fredraw_frame): Move actual code from here...
4099 (redraw_frame): ...to here. Add eassert. Adjust comment.
4100 (Fredraw_display): Use redraw_frame.
4101 * xdisp.c (clear_garbaged_frames): Likewise.
4103 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4105 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4106 passed to pint2str and pint2hrstr to be at most the size of the
4107 frame's decode_mode_spec_buffer. This avoids crashes with very
4108 large values of FIELD_WIDTH argument to decode_mode_spec.
4111 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4113 Fix a race with verify-visited-file-modtime (Bug#12863).
4114 Since at least 1991 Emacs has ignored an mtime difference of no
4115 more than one second, but my guess is that this was to work around
4116 file system bugs that were fixed long ago. Since the race is
4117 causing problems now, let's remove that code.
4118 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4119 whose time stamp is off by no more than a second. Insist that the
4120 file time stamps match exactly.
4122 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4124 * frame.h (struct frame): Convert external_tool_bar member to
4125 1-bit unsigned bitfield.
4126 * termhooks.h (struct terminal): Remove mouse_moved member since
4127 all users are long dead. Adjust comment on mouse_position_hook.
4129 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4131 Simplify by using FOR_EACH_FRAME here and there.
4132 * frame.c (next_frame, prev_frame, other_visible_frames)
4133 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4134 * w32term.c (x_window_to_scroll_bar): Likewise.
4135 * window.c (window_list): Likewise.
4136 * xdisp.c (x_consider_frame_title): Likewise.
4137 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4138 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4139 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4140 * xmenu.c (menubar_id_to_frame): Likewise.
4141 * xselect.c (frame_for_x_selection): Likewise.
4142 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4143 (x_window_to_menu_bar): Likewise.
4144 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4146 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4148 * data.c (Qdefalias_fset_function): Now static.
4150 Another tweak to vectorlike_header change.
4151 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4152 Remove, and replace all uses with ...
4153 (next_in_free_list, set_next_in_free_list):
4154 New functions, which respect C's aliasing rules better.
4156 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4158 * window.c (list4i): Rename from 'quad'. All uses changed.
4159 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4161 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4163 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence

4173 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4175 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4176 amount when the scroll margins are too large. When scrolling
4177 backwards in the buffer, give up if cannot reach point or the
4178 scroll margin within a reasonable number of screen lines.
4179 Fixes point position in window under scroll-up/down-aggressively when
4180 point is positioned many lines beyond the window top/bottom.
4183 * ralloc.c (relinquish): If real_morecore fails to return memory
4184 to the system, don't crash; instead, leave the last heap

4196 (Qdefalias_fset_function): New var.
4198 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4200 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4202 * nsfont.m (Qcondensed, Qexpanded): New variables.

4210 (SCROLL_BAR_VEC_SIZE): Remove.
4211 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4213 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4215 Tweak last vectorlike_header change.
4216 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4217 vectorlike object on the free list. This is introduced to avoid
4218 some (but not all) pointer casting and aliasing problems, see
4219 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4220 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike

4232 dynamic-docstring-function to replace the old ad-advice-info.
4234 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4236 * fns.c (Qeql, hashtest_eq): Now static.
4238 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4240 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4241 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4242 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

4249 * lisp.h (sxhash_combine): New inline function, with the contents
4250 of the old SXHASH_COMBINE.

4252 special hash function containing a comparison that always yields 1.
4254 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4256 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4257 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4258 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4261 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4263 * image.c (xpm_make_color_table_h): Fix compiler error because
4264 make_hash_table changed.
4266 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4268 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4270 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4272 Use ad-hoc comparison function for the profiler's hash-tables.
4273 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4274 (make_log): Use them.
4275 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4276 call Fequal any more.

4285 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4286 (hash_lookup, hash_remove_from_table): Move assertion checking of
4287 hashfn result here. Check hash-equality before calling cmpfn.

4299 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4300 value of w32-scroll-lock-modifier is neither nil nor one of the
4301 known key modifiers. (Bug#12806)
4303 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4305 Shrink struct vectorlike_header to the only size field.
4306 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4308 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4309 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4310 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4311 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4312 information from the vector header. Adjust comment.

4329 (allocate_vector_from_block): Simplify.
4330 (PSEUDOVECTOR_NBYTES): Replace with...
4331 (vector_nbytes): ...new function. Adjust users.
4332 (sweep_vectors): Adjust processing of large vectors.
4333 (allocate_vectorlike): Likewise.
4334 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4335 Add easserts. Adjust XSETPVECTYPESIZE usage.
4336 (allocate_buffer): Use BUFFER_PVEC_INIT.
4337 (live_vector_p): Adjust to match large vector.
4338 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4339 * buffer.h (struct buffer): Add next member.
4340 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4342 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

4348 (xvecsize): New command.
4350 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4352 * keyboard.c (event_to_kboard): Do not dereference
4353 frame_or_window field of SELECTION_REQUEST_EVENT
4354 and SELECTION_CLEAR_EVENT events (Bug#12814).
4355 * xterm.h (struct selection_input_event): Adjust comment.
4357 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4359 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4360 such as Scroll Lock, if the respective keys are treated as
4361 function keys, not as modifiers. This avoids destroying non-ASCII
4362 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4364 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4366 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4368 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4370 Restore some duplicate definitions (Bug#12814).
4371 This undoes part of the 2012-11-03 changes. Some people build
4372 with plain -g rather than with -g3, and they need the duplicate
4373 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4374 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4375 Define as macros, as well as as enums or as constants.
4377 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4379 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4380 to keypad keys (Bug#12816).
4382 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4384 Minor adjustments of recently-changed frame functions.
4385 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4386 known to be a frame (we're in the FRAMEP branch).
4387 * lisp.h (Qframep): Remove decl. frame.h declares this.
4388 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4389 since they're meant for Lisp fixnum values.
4391 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4393 * window.c (Fwindow_combination_limit): Revert to the only
4394 required argument and adjust docstring as suggested in
4395 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4396 by Martin Rudalics <rudalics@gmx.at>.
4398 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4400 Widely used frame validity and checking functions.
4401 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4402 * frame.c (decode_live_frame, decode_any_frame): New functions.
4403 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4404 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4405 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

4412 (frame_buffer_list, frame_buffer_predicate): Remove.
4413 * lisp.h (frame_buffer_predicate): Remove prototype.
4414 * buffer.c (Fother_buffer): Use decode_any_frame.
4415 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4416 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4417 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4418 (Fclose_font, Ffont_info): Use decode_live_frame.
4419 * fontset.c (check_fontset_name): Likewise.
4420 * terminal.c (Fframe_terminal): Likewise.
4421 * w32fns.c (check_x_frame): Likewise.
4422 * window.c (Fminibuffer_window, Fwindow_at)
4423 (Fcurrent_window_configuration): Likewise.
4424 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4425 Likewise. Allow zero number of arguments. Adjust docstring.
4426 * dispnew.c (Fredraw_frame): Likewise.
4427 * xfaces.c (frame_or_selected_frame): Remove.
4428 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4429 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4430 (Fframe_face_alist): Use decode_live_frame.
4431 * xfns.c (check_x_frame): Likewise.
4433 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4435 * window.c (quad): New function.
4436 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4437 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4438 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4439 (Fwindow_line_height): Use it.
4440 (Fwindow_fringes): Use list3.
4441 (Fwindow_scroll_bars): Use list4.
4442 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4443 (Fwindow_combination_limit): Allow zero number of arguments.
4445 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4447 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4449 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4450 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4451 file descriptor 2 for standard error. (Bug#12805)
4453 2012-11-05 Chong Yidong <cyd@gnu.org>
4455 * process.c (wait_reading_process_output): Revert previous change.
4457 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4459 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4460 This removes code that has been obsolete since around 1990.
4461 * callproc.c (Fcall_process):
4463 * process.c (create_process):
4464 * term.c (dissociate_if_controlling_tty):
4465 Assume setsid exists.
4466 * callproc.c (child_setup): Assume setpgid exists and behaves as
4467 per POSIX.1-1988 or later.
4468 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4469 * emacs.c (shut_down_emacs):
4470 * sysdep.c (sys_suspend, init_foreground_group):
4471 Assume getpgrp behaves as per POSIX.1-1998 or later.
4472 * msdos.c (setpgrp): Remove.
4473 (tcgetpgrp, setpgid, setsid): New functions.
4474 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4475 * term.c (no_controlling_tty): Remove; unused.
4476 * w32proc.c (setpgrp): Remove.
4477 (setsid, tcgetpgrp): New functions.
4479 Simplify by assuming __fpending.
4480 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4481 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4482 Do not assume that __fpending's result fits in int.
4484 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4486 Remove EMACS_OUTQSIZE+sleep hack.
4487 * dispnew.c (update_frame_1): Remove hack for terminals slower
4488 than 2400 bps, which throttled Emacs by having it sleep.
4489 This code hasn't worked since at least 2007, when the multi-tty stuff
4490 was added, and anyway those old terminals are long dead.
4491 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4492 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4494 Fix data-loss with --version (Bug#9574).
4495 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4496 as we can't assume that emacs_strerror is initialized, and strerror
4497 is good enough here.
4498 (main): Invoke atexit earlier, to catch earlier instances of
4499 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4501 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4503 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4504 (keyDown): Remap keypad keys to X11 virtual key codes.
4506 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4508 Fix data-loss with --batch (Bug#9574).
4509 * emacs.c: Include <close-stream.h>.
4510 (close_output_streams): New function.
4511 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4512 and handles errors appropriately.
4513 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4516 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4517 The symptom is a diagnostic "GLib-WARNING **: In call to
4518 g_spawn_sync(), exit status of a child process was requested but
4519 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4520 waitpid(), so exit status can't be returned." The diagnostic
4521 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4522 The real bug is a race condition between Emacs and glib: Emacs
4523 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4524 so that glib can't find it. Work around the bug by invoking
4525 waitpid only on subprocesses that Emacs itself creates.
4526 * process.c (create_process, record_child_status_change):
4527 Don't use special value -1 in pid field, as the caller now must
4528 know the pid rather than having the callee infer it.
4529 The inference was sometimes incorrect anyway, due to another race.
4530 (create_process): Set new 'alive' member if child is created.
4531 (process_status_retrieved): New function.
4532 (record_child_status_change): Use it.
4533 Accept negative 1st argument, which means to wait for the
4534 processes that Emacs already knows about. Move special-case code
4535 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4536 processes that have already been waited for, by testing and
4537 clearing new 'alive' member.
4538 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4539 now does this internally.
4540 (handle_child_signal): Let record_child_status_change do all
4541 the work, since we do not want to reap all exited child processes,
4542 only the child processes that Emacs itself created.
4543 * process.h (Lisp_Process): New boolean member 'alive'.
4545 Omit duplicate definitions no longer needed with gcc -g3.
4546 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4547 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4548 Define only as macros. There's no longer any need to also define
4549 these symbols as enums or as constants, since we now assume
4550 gcc -g3 when debugging.
4552 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4554 * lisp.mk: Adjust comments to the fact that term/internal is now
4555 loaded from loadup.el.
4557 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4558 (msdos_fatal_signal): New function.
4559 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4562 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4563 for GCC versions before 4.
4564 (emacs_raise): Define to call msdos_fatal_signal.
4566 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4567 iterator when starting in the middle of a display or overlay
4570 2012-11-03 Chong Yidong <cyd@gnu.org>
4572 * process.c (wait_reading_process_output): Clean up the last
4575 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4577 * process.c (wait_reading_process_output): Avoid a race condition
4578 with SIGIO delivery (Bug#11536).
4580 2012-11-03 Chong Yidong <cyd@gnu.org>
4582 * buffer.c (cursor_type): Untabify docstring.
4584 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4586 * frame.h (struct frame): Drop can_have_scroll_bars member
4587 which is meaningless for a long time. Adjust comments.
4588 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4589 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4591 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4593 * window.c (decode_next_window_args): Update window arg after
4594 calling decode_live_window and so fix crash reported at
4595 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4596 by Juanma Barranquero <lekktu@gmail.com>.
4597 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4598 * font.c (Ffont_at): Likewise.

4632 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4634 Remove pad from struct input_event.
4635 * termhooks.h (struct input_event): Remove padding field.
4637 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4638 member is never cons for a long time. Adjust comment.
4639 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4640 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4641 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4642 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4644 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4646 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4648 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4650 Fix crash when using Emacs as commit editor for git (Bug#12697).
4651 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4652 and it is configured in conf_post.h.
4653 (Fcall_process): Don't invoke both setsid and setpgid; the former
4654 is enough, if it exists.
4655 * callproc.c (Fcall_process, child_setup):
4656 * process.c (create_process): Use setpgid.
4657 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4659 * dispnew.c (init_display): Initialize the foreground group
4660 if we are running a tty display.
4661 * emacs.c (main): Do not worry about setpgrp; init_display does it now.

4669 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4671 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4673 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4675 * minibuf.c (read_minibuf): Restore current buffer since
4676 choose_minibuf_frame calling Fset_frame_selected_window may
4677 change it (Bug#12766).

4685 * font.c (Ffont_at): If WINDOW is specified and it is not
4686 displaying the current buffer, signal an error.
4688 2012-10-29 Daniel Colascione <dancol@dancol.org>
4690 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4691 In preparation for fixing bug#12739, move these functions from
4694 * coding.h, coding.c: ... to here, and compile them only when
4695 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4696 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4698 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4700 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4701 (timer_loop, getitimer, setitimer): Use it instead of

4704 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4707 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>

4713 of [last_appdefined_event data1].
4714 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4715 remove last_appdefined_event (Bug#12698).
4717 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4719 * frame.c (x_set_font): Catch internal error.
4721 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4723 Avoid overflow in w32 implementation of interval timers.
4724 When possible, for ITIMER_PROF count only times the main thread
4726 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4727 'volatile ULONGLONG' types. All the other data which was
4728 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4729 (GetThreadTimes_Proc): New typedef.
4730 (w32_get_timer_time): New function, returns a suitable time value
4732 (timer_loop): Enter critical section when accessing ULONGLONG
4733 values of the itimer_data struct, as these accesses are no longer
4734 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4735 Remove unused variable.
4736 (init_timers): Initialize s_pfn_Get_Thread_Times.
4737 (start_timer_thread): Don't assign itimer->caller_thread here.

4744 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4745 mouse movement events if the menu bar is active. This avoids
4746 producing a busy "hour-glass" cursor by Windows if the mouse
4747 pointer is positioned over a tooltip shown for some menu item.
4749 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4751 Don't assume process IDs fit in int.
4752 * emacs.c (shut_down_emacs) [!DOS_NT]:
4753 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4754 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4755 Use pid_t, not int, to store process IDs, as 'int'
4756 is not wide enough on a few platforms (e.g., AIX and IRIX).
4758 2012-10-23 Kenichi Handa <handa@gnu.org>
4760 The following change is to make face-font-rescale-alist work
4761 correctly for non-ASCII fonts.

4781 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4783 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4785 Port to OpenBSD 5.1.
4786 * frame.c (Fmouse_position, Fmouse_pixel_position):
4787 * xdisp.c (produce_stretch_glyph):
4788 Declare local vars only when they're needed.
4789 This is clearer and avoids a warning on OpenBSD about unused vars.

4791 This is safer, and avoids OpenBSD warnings about unused vars.
4792 * keyboard.c (record_menu_key): Remove unnecessary decl.
4793 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4794 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4795 as our definition clashes with OpenBSD's.
4796 * xfaces.c (load_face_colors, check_lface_attrs)
4797 (get_lface_attributes_no_remap, get_lface_attributes)
4798 (lface_fully_specified_p, x_supports_face_attributes_p)
4799 (tty_supports_face_attributes_p, face_fontset, realize_face)
4800 (realize_x_face, realize_tty_face):
4801 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4802 merely Lisp_Object *. This is more informative and avoids
4803 a warning on OpenBSD about accessing beyond an object's size.
4805 2012-10-20 Chong Yidong <cyd@gnu.org>
4807 * lread.c (Fload): Doc fix (Bug#12592).

4833 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4834 (staticpro): If we run out of staticpro slots, die with an
4835 informative error instead of just calling emacs_abort.
4837 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4839 Fix two flaws reported by Dmitry Antipov.

5091 (detect_input_pending_run_timers):
5092 * process.c (wait_reading_process_output):
5093 Use unsigned for counter where wraparound-on-overflow is desired,
5094 since unsigned is guaranteed to have that behavior and signed is not.
5095 (read_char): Use ptrdiff_t for string length.
5096 (get_input_pending): Remove first argument, since it was always
5097 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5098 and behave as if it had that value. Return new value of
5099 input_pending. All callers changed.
5100 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5101 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's
5103 * keymap.c (push_key_description): Omit last arg, which was always 1.
5104 All callers changed.
5106 * regex.c (immediate_quit) [emacs]: Remove duplicate decl.

5119 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5121 Clean out old termopts cruft.
5122 * termopts.h (flow_control, meta_key): Remove unused decls.
5123 * dispnew.c, indent.c, nsterm.m, term.c, xsettings.c, xsmfns.c:
5124 Don't include termopts.h.
5126 2012-10-10 Dmitry Antipov <dmantipov@yandex.ru>
5128 * alloc.c (gc_sweep): Use pointer-to-a-pointer loop for buffers.
5130 2012-10-10 Paul Eggert <eggert@cs.ucla.edu>
5132 * commands.h (immediate_quit): Remove duplicate decl.
5134 2012-10-09 Jan Djärv <jan.h.d@swipnet.se>
5136 * nsfont.m (Vfonts_in_cache): Remove, not needed as font.c handles
5138 (nsfont_open): Remove setting of Vfonts_in_cache.
5139 (syms_of_nsfont): Remove initialization of Vfonts_in_cache.
5141 2012-10-09 Eli Zaretskii <eliz@gnu.org>
5143 * w32fns.c (w32_last_error): Change the return value to DWORD, to
5144 match what GetLastError returns. Explain why the function is
5147 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5148 'is_tooltip_frame', to avoid confusion with its global namesake.
5150 2012-10-08 Daniel Colascione <dancol@dancol.org>
5152 * xdisp.c (start_hourglass): Call w32_note_current_window when
5153 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5154 build that caused Emacs to display the hourglass cursor forever.
5156 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5157 which is broken under remote desktop, calculate the number of
5158 colors available for a display based on the display's number of
5159 planes and number of bits per pixel per plane. (bug#10397).
5161 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5163 * nsfont.m (Vfonts_in_cache): New variable.
5164 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5165 are used. Add cached fonts to Vfonts_in_cache.
5166 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5168 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5170 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5172 (FONT_H): Define after FRAME_H.
5173 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5174 Update dependencies.
5176 * w32term.c: Remove leftover declaration of keyboard_codepage.
5178 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5180 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5181 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5182 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5183 (GLOBAL_SOURCES): Add cygw32.c.

5189 ($(BLD)/w32menu.$(O)):
5190 ($(BLD)/w32proc.$(O)): Add w32common.h.
5192 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5194 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5196 2012-10-08 Daniel Colascione <dancol@dancol.org>
5198 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5199 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5200 accidental message numbering hole. Change other messages to
5203 * w32select.h (HAVE_W32SELECT): Remove.
5205 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5206 w32common.h instead of w32heap.h.

5216 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5217 (w32_minor_version, w32_build_number, w32_subtype):
5218 Remove duplicate definitions.
5220 * w32fns.c: Include w32common.h; include w32heap.h only in
5223 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5224 Use `report_file_error' instead of `error' in order to better
5225 inform users of what went wrong. Increase NTGUI_UNICODE file
5226 dialog box file name length to 32k, the maximum allowed by the NT
5229 * w32common.h: New file.
5230 (ROUND_UP, ROUND_DOWN, get_page_size)
5231 (get_allocation_unit, get_processor_type, get_w32_major_version)
5232 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5233 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5234 (OS_NT, os_subtype, cache_system_info): Move here.
5236 * unexw32.c, unexcw.c: Include w32common.h.
5238 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5239 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5240 to call syms_of_w32select.
5242 * cygw32.h: Remove obsolete EXFUN declarations.
5244 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5246 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5247 of w32inevt.o from SOME_MACHINE_OBJECTS.
5249 2012-10-08 Daniel Colascione <dancol@dancol.org>
5251 * image.c: Permanent fix for JPEG compilation issue --- limit
5252 jpeglib `boolean' redefinition to Cygwin builds.
5254 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5256 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5258 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5261 2012-10-08 Daniel Colascione <dancol@dancol.org>
5263 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5264 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,

5267 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5268 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5269 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5270 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5271 now a supported configuration.
5273 * Makefile.in: consolidate image variables into LIBIMAGE; add
5274 W32_OBJ and W32_LIBS. Compile new files.
5277 (_DebPrint) declare tracing facility for W32 debugging. We need
5278 to unify tracing later.
5280 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5281 unconditional use of W32 Unicode functions. Cygwin runs only on
5282 100% Unicode operating systems.
5284 * cygw32.c: New file. Define Cygwin-specific facilities.
5285 (Fcygwin_convert_path_to_windows)
5286 (Fcygwin_convert_path_from_windows): New user functions for
5287 accessing Cygwin path-munging routines.
5289 * cygw32.h: New file.
5290 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5291 UTF-16LE strings temporarily inside non-Lisp-visible string
5294 (w32_strerror): Just what it says on the tin.
5296 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5297 also run for Cygwin; both systems have the same problem with using
5298 GUI facilities in a forked child. Also call syms_of_cygw32,
5299 syms_of_w32select in correct places.
5301 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5302 needs fork-then-exec for daemon launching.
5304 * font.h: Include frame.h.
5306 * image.c: Use the image library cache machinery only when we're
5307 compiling for native WINDOWSNT; Cygwin can use shared libraries
5308 like any other Unixlike system.
5310 * keyboard.c: Clarify a comment regarding the input loop.
5312 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5313 functions directly instead of trying to detect at runtime that our
5314 host operating system supports them. We make this change for two
5315 reasons: Cygwin lacks support for the multibyte character
5316 conversion functions used by the legacy menu code, and Cygwin
5317 never needs to rely on non-Unicode APIs.
5319 * unexw32.c (hinst): Declare extern.
5321 * w32.c: Change header order;
5322 (w32_strerror): Move to w32fns.c because we need it for
5323 non-WINDOWSNT builds.
5325 * w32.h: Add #error macro to make sure we don't include w32.h for
5326 Cygwin builds. Remove w32select declarations.
5328 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5329 w32fns.c. w32console.c is WINDOWSNT-only.
5331 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5332 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5334 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5335 (w32_major_version, w32_minor_version, w32_build_number)
5336 (os_subtype, sound_type): Define here
5337 (w32_defined_color): Make color parameter const for consistency
5338 with other _defined_color functions.
5339 (w32_createwindow): Unconditionally call w32_init_class instead of
5340 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5341 through the code is complex and unnecessary because class
5342 registration is practically free.
5343 (w32_name_of_message): New EMACSDEBUG-only function.
5344 (Fset_message_beep): Move here
5345 (Fx_open_connection): Require that the display name for Windows be
5346 "w32" for consistency, emacsclient disambiguation, and maybe, one
5347 day, multi-window-system support.
5348 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5349 Cygwin files for W32 GUI facilities, since these clearly don't
5350 expect Cygwin names.
5351 (_DebPrint): Define.
5352 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5353 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5354 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5355 (w32_last_error): Remove.
5357 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5359 * w32heap.c (syspage_mask): Declare here.
5360 (cache_system_info): Remove.
5362 * w32inevt.c (faked_key): Define globally, not statically.
5363 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5364 (w32_console_toggle_lock_key): Move to w32fns.c.
5366 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5368 * w32proc.c (_DebPrint): Move to w32fns.c.
5369 * w32select.c: Include string.h, stdio.h for Cygwin.
5370 * w32select.h: New File.
5372 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5374 (w32_message_fd): New variable. Under Cygwin, holds the file
5375 descriptor the system used to tell us about pending thread
5378 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5379 that prevented compilation under non-WINDOWSNT systems.
5381 (w32_initialize): Open /dev/windows and assign it to
5382 w32_message_fd. Provide w32 feature.
5384 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5385 (WM_EMACS_INPUT_READY): add.
5386 (prepend_msg, w32_message_fd): Declare globally.
5389 (keyboard_handle): Use only when WINDOWSNT.
5390 (notify_msg_ready): New function. Posts a message to the main
5391 thread's message queue under CYGWIN, which wakes up the main
5392 thread from select(2) by making the /dev/windows file descriptor
5393 ready. Under WINDOWSNT, it sets an event the same way the old
5396 (post, prepend_msg): Actually call notify_msg_ready instead of
5397 setting the input event directly.
5399 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5401 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5402 but it still has blocs in it, don't return it to the system,
5403 instead of aborting. (Bug#12402)
5405 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5407 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5409 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5410 MAC_OS_X_VERSION_10_6.
5411 (syms_of_nsterm): Remove comment about Panther and above for
5413 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5414 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5415 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5417 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5418 MAC_OS_X_VERSION_10_4.
5420 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5421 MAC_OS_X_VERSION_10_2.
5423 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5425 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5426 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5428 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5429 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5430 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5431 Remove ns_in_resize check.
5432 (ns_clear_frame_area): Remove resize handle code.
5434 * nsfns.m (ns_in_resize): Remove.
5435 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5436 Remove ns_in_resize check.
5438 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5440 Improve sys_siglist detection.
5441 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5442 defined as a macro, as is done in Solaris.
5443 (sys_siglist_entries): New macro.
5444 (save_strsignal): Use it.
5445 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5446 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5448 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5450 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5451 fullscreen/Fullscreen.
5453 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5454 tobar_height is new.
5456 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5457 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5458 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5459 (windowDidResize:): Check for correct window if old style fullscreen.
5460 Capitalize word in comment. Remove incorrect comment.
5461 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5462 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5463 error in drawing background.
5464 (toggleFullScreen:): Remove comment. Rearrange calls.
5465 Set toolbar values to zero, save old height in tobar_height.
5466 Restore tool bar height when leaving fullscreen.
5467 (canBecomeMainWindow): New function.
5469 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5471 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5473 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5475 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5477 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5478 that time stamps of directories could also be changed.
5479 Don't request the too broad GENERIC_WRITE, only the more restrictive
5480 FILE_WRITE_ATTRIBUTES access rights.
5482 * fileio.c (Fset_file_times): Special-case ignoring errors for
5483 directories only on MSDOS, not on MS-Windows.
5485 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5487 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5489 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5491 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5492 see whether CreateFile failed.
5494 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5496 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5497 to avoid similar races.
5498 * keyboard.c (pending_signals): Now bool, not int.
5500 Port timers to OpenBSD, plus check for timer failures.
5501 OpenBSD problem reported by Han Boetes.
5502 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5504 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5505 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5506 like OpenBSD, which has timer_settime but does not declare it.
5507 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5508 whether to use itimerspec-related primitives. All uses of
5509 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5511 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5513 * profiler.c (handle_profiler_signal): Fix a malloc race
5514 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5516 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5518 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5520 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5522 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5523 consistent with the change in return value of 'safe_strsignal'.
5525 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5527 Prefer plain 'static' to 'static inline' (Bug#12541).
5528 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5529 (bidi_set_sor_type, bidi_push_embedding_level)
5530 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5531 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5532 (bidi_cache_search, bidi_cache_ensure_space)
5533 (bidi_cache_iterator_state, bidi_cache_find)
5534 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5535 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5536 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5537 Now 'static', not 'static inline'.
5539 Count overruns when profiling; change units to ns.
5540 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5541 Give extra weight to samples after overruns, to attempt to count
5542 the time more accurately.
5543 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5544 the underlying primitives nominally do ns.
5545 (Fprofiler_cpu_start): Document the change. Mention that
5546 the sampling intervals are only approximate.

5566 Fix a malloc race condition involving strsignal.
5567 A signal can arrive in the middle of a malloc, and Emacs's signal
5568 handler can invoke strsignal, which can invoke malloc, which is
5569 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5570 Fix it by altering the signal handler so that it does not invoke
5572 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5573 * process.c (status_message): Use const pointer, in case strsignal
5574 is #defined to safe_strsignal.
5575 * sysdep.c (sys_siglist, init_signals): Always define and
5576 initialize a substitute sys_siglist if the system does not define
5577 one, even if HAVE_STRSIGNAL.
5578 (safe_strsignal): Rename from strsignal. Always define,
5579 using sys_siglist. Return a const pointer.
5580 * syssignal.h (safe_strsignal): New decl.
5581 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5583 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5585 * w32proc.c (timer_loop): Fix code that waits for timer
5586 expiration, to avoid high CPU usage.
5588 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5590 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5591 (sweep_weak_table): Remove redundant prototypes.
5593 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5595 * emacs.c: Move the inclusion of TERM_HEADER after including
5596 windows.h on WINDOWSNT. This avoids compilation problems with
5599 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5601 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5602 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5603 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5604 as the previous version used 'void *'.
5606 * ralloc.c (ROUNDUP): Fix last change.
5607 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5610 * w32proc.c <disable_itimers>: New static flag.
5611 (init_timers): Initialize it to zero, after creating the critical
5612 sections used by the timer threads.
5613 (term_timers): Set to 1 before deleting the critical sections.
5614 (getitimer, setitimer): If disable_itimers is non-zero, return an
5615 error indication without doing anything. Reported by Fabrice
5616 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5617 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5619 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5622 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5623 term_ntproc after all the other bookkeeping, to get timers working
5624 as long as possible.
5626 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5628 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5629 Suggested by Juri Linkov in
5630 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5632 Prefer plain 'static' to 'static inline' (Bug#12541).
5633 With static functions, modern compilers inline pretty well by
5634 themselves; advice from programmers often hurts as much as it helps.
5635 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5636 this change shrinks the text size of the Emacs executable by 1.1%
5637 without affecting CPU significantly in my benchmark.

5718 (bidi_char_at_pos): Merge the two STRING_CHAR calls into one.
5720 Revert the FOLLOW-SYMLINKS change for file-attributes.
5721 Doing it right would require several changes to Tramp, and there's
5722 not enough time to get that tested before the freeze today.
5723 * dired.c (directory_files_internal, Ffile_attributes):
5726 * frame.c (x_report_frame_params): Port better to wider ints.
5727 Do not assume that EMACS_UINT is the same width as uprintmax_t,

5760 * w32.c (init_environment, get_emacs_configuration): Support AMD64
5762 (init_ntproc): Cast arguments of _open_osfhandle to intptr_t, for
5763 compatibility with x64.
5765 * vm-limit.c (lim_data): Now size_t.
5766 (check_memory_limits): Adjust prototypes of real_morecore and
5767 __morecore to receive argument of type ptrdiff_t. Use size_t for

5794 value of FRAME_X_WINDOW, to fit a 64-bit pointer on 64-bit Windows

5916 HAVE_TIMER_SETTIME is defined.
5918 2012-09-30 Paul Eggert <eggert@cs.ucla.edu>
5920 Profiler improvements: more-accurate timers, overflow checks.
5921 * profiler.c: Don't include stdio.h, limits.h, sys/time.h,
5922 signal.h, setjmp.h. Include systime.h instead.
5923 (saturated_add): New function.
5924 (record_backtrace, current_sample_interval): Use EMACS_INT, not size_t.

5930 All uses changed to store the new value.
5931 (handle_profiler_signal): Rename from sigprof_handler_1,
5932 for consistency with other handlers. Do not check whether
5933 cpu_log is a hash-table if garbage collecting, since it
5934 doesn't matter in that case.
5935 (deliver_profiler_signal): Rename from sigprof_handler,
5936 for consistency with other handlers.
5937 (setup_cpu_timer): New function, with much of what used to be in
5938 Fprofiler_cpu_start. Check for out-of-range argument.
5939 Prefer timer_settime if available, and prefer
5940 thread cputime clocks, then process cputime clocks, then
5941 monotonic clocks, to the old realtime clock. Use make_timeval
5942 to round more-correctly when falling back to setitimer.
5943 (Fprofiler_cpu_start): Use it.
5944 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5945 Don't assume that passing NULL as the 2nd argument of setitimer
5946 is the same as passing a pointer to all-zero storage.
5947 Ignore SIGPROF afterwards.
5948 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5949 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5950 non-fatal signal handlers. Ignore SIGPROF on startup.
5951 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5952 in profiler.c, since sysdep.c now uses it.
5954 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

5991 Check more robustly for timer_settime.
5992 * Makefile.in (LIB_TIMER_TIME): New macro.
5994 * atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
5995 Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
5998 2012-09-26 Tomohiro Matsuyama <tomo@cx4a.org>
6000 * profiler.c (Fprofiler_cpu_start): Remove unnecessary flag SA_SIGINFO.

6004 * makefile.w32-in ($(BLD)/profiler.$(O)): Update dependencies.
6006 2012-09-26 Paul Eggert <eggert@cs.ucla.edu>
6008 * character.h (MAYBE_UNIFY_CHAR): Remove.
6009 * charset.c, charset.h (maybe_unify_char): Now static.
6010 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
6011 Since this stuff is now private to charset.c, there's no need for
6012 a public macro and no need to inline by hand.

6041 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
6043 * makefile.w32-in ($(BLD)/callproc.$(O)): Update dependencies.
6045 2012-09-25 Paul Eggert <eggert@cs.ucla.edu>
6047 Prefer POSIX timers if available.
6048 They avoid a race if the timer is too close to the current time.
6049 * atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
6050 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
6051 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
6053 2012-09-25 Eli Zaretskii <eliz@gnu.org>

6062 Move Vlibrary_cache to emacs.c and reset before dumping.
6064 * lisp.h (reset_image_types): Declare.
6065 [WINDOWSNT] (Vlibrary_cache): Declare.
6067 * image.c (reset_image_types): New function.
6069 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.

6076 * w32.h (Vlibrary_cache): Do not declare.
6078 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6080 * w32proc.c (sys_signal): Handle all signals defined by the
6081 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6082 handlers for signals supported by Windows. Don't override
6083 term_ntproc as the handler for SIGABRT.
6084 (sigaction): Rewrite to call sys_signal instead of duplicating its
6086 (sys_kill): Improve commentary.
6088 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6089 consistency with a signature of a signal handler. All callers
6091 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6092 install term_ntproc as a signal handler for SIGABRT, as that
6093 should be done by the dumped Emacs.
6095 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6097 * w32select.c (term_w32select): Protect against repeated
6098 invocation by setting clipboard_owner to NULL after calling

6102 and term_ntproc to their modified signatures.
6104 * character.c (char_string, string_char): Remove calls to
6105 MAYBE_UNIFY_CHAR. See the discussion starting at

6109 2012-09-25 Chong Yidong <cyd@gnu.org>
6111 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
6113 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6115 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6116 when encountering an unknown bytecode.
6118 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6120 image.c, indent.c: Use bool for booleans.
6121 * dispextern.h (struct image_type): Members valid_p, load, init
6122 now return bool, not int. All uses changed.
6123 * image.c: Omit unnecessary static decls.
6124 (x_create_bitmap_mask, x_build_heuristic_mask):
6125 Return void, not int, since callers don't care about the return value.

6160 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6162 Move pid_t related decls out of lisp.h.
6163 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6164 (interruptible_wait_for_termination):
6165 Move these decls from lisp.h to syswait.h, since they use pid_t.
6166 Needed on FreeBSD; see Herbert J. Skuhra in
6167 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6168 * callproc.c: Include syswait.h.

6186 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):

6188 Use bool for boolean.
6189 * gtkutil.c (xg_update_frame_menubar):
6190 * xmenu.c (update_frame_menubar):
6191 Return void, not int, since caller ignores return value.

6195 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6197 * makefile.w32-in (BLOCKINPUT_H): Remove.

6214 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6216 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6217 fatal_error_backtrace.
6219 * w32proc.c (sys_kill): Undo last change: don't do anything when
6220 invoked to deliver SIGABRT to our own process. This is now
6221 handled by emacs_raise.
6223 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6225 * w32term.c (w32_read_socket): Remove leftover reference to
6226 interrupt_input_pending.
6228 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6230 Do not use SA_NODEFER.
6231 Problem reported by Dani Moncayo in
6232 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6234 * sysdep.c (emacs_abort): Do not reset signal handler.
6235 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6236 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6237 wanted even on POSIXish hosts, and it doesn't work on Windows.
6239 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6241 * xterm.c (x_term_init): Call fixup_locale before and after calling
6242 gtk_init (Bug#12392).
6244 2012-09-23 Chong Yidong <cyd@gnu.org>
6246 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6247 Vdynamic_library_alist.
6249 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6250 (Fgnutls_available_p): Caller changed.
6252 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6253 (Flibxml_parse_xml_region): Likewise.
6255 * dispextern.h (struct image_type): Remove arg from init function.
6257 * image.c (Finit_image_library, lookup_image_type)
6258 (define_image_type): Remove now-unneeded second arg.
6259 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6260 (init_tiff_functions, init_gif_functions, init_svg_functions):
6261 Arglist and w32_delayed_load calling convention changed.
6262 (gs_type): Remove init_gs_functions; there is no such function.
6263 (valid_image_p, make_image): Fix caller to lookup_image_type.
6265 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6267 Simplify and avoid signal-handling races (Bug#12471).
6269 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6270 Avoid recursive loop if there's a fatal error in the function itself.
6271 * atimer.c (pending_atimers):
6272 * blockinput.h: Don't include "atimer.h"; no longer needed.
6273 (interrupt_input_pending): Remove. All uses removed.
6274 pending_signals now counts both atimers and ordinary interrupts.
6275 This is less racy than having three separate pending-signal flags.
6276 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6278 Rename from their upper-case counterparts BLOCK_INPUT,
6279 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6280 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6281 This makes it easier to access volatile variables more accurately.
6282 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6283 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6284 that's more reliable if the code is buggy and sets
6285 interrupt_input_blocked to a negative value. All uses changed.
6286 * atimer.c (deliver_alarm_signal):
6287 Remove. No need to deliver this to the parent; any thread can
6288 handle this signal now. All uses replaced by underlying handler.
6289 * atimer.c (turn_on_atimers):
6290 * dispnew.c (handle_window_change_signal):
6291 * emacs.c (handle_danger_signal):
6292 * keyboard.c (kbd_buffer_get_event):
6293 Don't reestablish signal handler; not needed with sigaction.
6294 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6296 Rework to avoid unnecessary accesses to volatile variables.
6297 (UNBLOCK_INPUT_TO): Now a function.
6298 (totally_unblock_input, unblock_input): New decls.
6299 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6300 (init_data): Remove. Necessary stuff now done in init_signal.
6301 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6302 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6303 (fatal_error_code): Remove; no longer needed.
6304 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6305 it doesn't always backtrace. All uses changed. No need to reset
6306 signal to default, since sigaction and/or die does that for us now.
6307 Use emacs_raise (FOO), not kill (getpid (), FOO).
6308 (main): Check more-accurately whether we're dumping.
6309 Move fatal-error setup to sysdep.c
6310 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6311 * gtkutil.c (xg_get_file_name, xg_get_font):
6312 Remove no-longer-needed signal-mask manipulation.
6313 * keyboard.c, process.c (POLL_FOR_INPUT):
6314 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6315 * keyboard.c (read_avail_input): Remove.
6316 All uses replaced by gobble_input.
6317 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6318 (kbd_buffer_store_event_hold, gobble_input):
6319 (record_asynch_buffer_change) [USABLE_SIGIO]:
6320 (store_user_signal_events):
6321 No need to mess with signal mask.
6322 (gobble_input): If blocking input and there are terminals, simply
6323 set pending_signals to 1 and return. All hooks changed to not
6324 worry about whether input is blocked.
6325 (process_pending_signals): Clear pending_signals before processing
6326 them, in case a signal comes in while we're processing.
6327 By convention callers now test pending_signals before calling us.
6328 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6329 New functions, to support changes to blockinput.h.
6330 (handle_input_available_signal): Now extern.
6331 (reinvoke_input_signal): Remove. All uses replaced by
6333 (quit_count): Now volatile, since a signal handler uses it.
6334 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6335 All callers changed. Block SIGINT only if not already blocked.
6336 Clear sigmask reliably, even if Fsignal returns, which it can.
6337 Omit unnecessary accesses to volatile var.
6338 (quit_throw_to_read_char): No need to restore sigmask.
6339 * keyboard.c (gobble_input, handle_user_signal):
6340 * process.c (wait_reading_process_output):
6341 Call signal-handling code rather than killing ourselves.
6342 * lisp.h: Include <float.h>, for...
6343 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6344 (pending_signals): Now volatile.
6345 (syms_of_data): Now const if IEEE floating point.
6346 (handle_input_available_signal) [USABLE_SIGIO]:
6347 (terminate_due_to_signal, record_child_status_change): New decls.
6348 * process.c (create_process): Avoid disaster if memory is exhausted
6349 while we're processing a vfork, by tightening the critical section
6351 (send_process_frame, process_sent_to, handle_pipe_signal)
6352 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6354 (send_process): No need for setjmp/longjmp any more, since the
6355 SIGPIPE stuff is now gone. Instead, report an error if errno
6357 (record_child_status_change): Now extern. PID and W are now args.
6358 Return void, not bool. All callers changed.
6359 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6360 Remove. All uses removed. This bug should be fixed now in a
6362 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6363 and record the child status change directly. This avoids the
6364 need to futz with the signal mask.
6365 (process_fatal_action): Move here from emacs.c.
6366 (emacs_sigaction_flags): New function, containing
6367 much of what used to be in emacs_sigaction_init.
6368 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6369 caught by emacs, to make races less likely.
6370 (deliver_process_signal): Rename from handle_on_main_thread.
6372 (BACKTRACE_LIMIT_MAX): Now at top level.
6373 (thread_backtrace_buffer, threadback_backtrace_pointers):
6375 (deliver_thread_signal, deliver_fatal_thread_signal):
6376 New functions, for more-accurate delivery of thread-specific signals.
6377 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6378 (deliver_arith_signal): Handle in this thread, not
6379 in the main thread, since it's triggered by this thread.
6380 (maybe_fatal_sig): New function.
6381 (init_signals): New arg DUMPING so that we can be more accurate
6382 about whether we're dumping. Caller changed.
6383 Treat thread-specific signals differently from process-general signals.
6384 Block all signals while handling fatal error; that's safer.
6385 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6387 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6388 Ignore SIGPIPE unless batch.
6389 (emacs_backtrace): Output backtrace for the appropriate thread,
6390 which is not necessarily the main thread.
6391 * syssignal.h: Include <stdbool.h>.
6392 (emacs_raise): New macro.
6393 * xterm.c (x_connection_signal): Remove; no longer needed
6394 now that we use sigaction.
6395 (x_connection_closed): No need to mess with sigmask now.
6396 (x_initialize): No need to reset SIGPIPE handler here, since
6397 init_signals does this for us now.
6399 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6401 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6402 background rect may be larger (Bug#12245).
6404 2012-09-23 Chong Yidong <cyd@gnu.org>
6406 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6408 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6410 * .gdbinit: Just stop at fatal_error_backtrace.
6411 See Stefan Monnier's request in
6412 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6413 Remove no-longer-used query of system type.
6415 2012-09-22 Chong Yidong <cyd@gnu.org>
6417 * search.c (Freplace_match): Doc fix (Bug#12325).
6419 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6421 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6422 (Fline_end_position): Doc fix.
6424 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6426 2012-09-22 Chong Yidong <cyd@gnu.org>
6428 * dispextern.h (struct image_type): Add new slot, storing a type
6429 initialization function.
6431 * image.c (define_image_type): Call the image initializer function
6432 if it is defined. Arguments and return value changed.
6433 (valid_image_p, make_image): Callers changed.
6434 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6435 (gif_type, imagemagick_type, svg_type, gs_type):
6436 Add initialization functions.
6437 (Finit_image_library): Call lookup_image_type.
6438 (CHECK_LIB_AVAILABLE): Macro deleted.
6439 (lookup_image_type): Call define_image_type here, rather than via
6440 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6441 (syms_of_image): Move define_image_type calls for xbm_type and
6442 pbm_type to lookup_image_type.
6444 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6446 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6447 'idle_timers' from here ...
6448 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6449 lists, to avoid infloops when the timer does something stupid,
6450 like reinvoke itself with the same or smaller time-out.
6453 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6455 * window.c (Fsplit_window_internal): Handle only Qt value of
6456 Vwindow_combination_limit separately.
6457 (Qtemp_buffer_resize): New symbol.
6458 (Vwindow_combination_limit): New default value.
6461 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6463 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6464 the new overlay string. (Bug#10159)
6466 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6468 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6469 or that fprintf is async-signal-safe. POSIX doesn't require
6472 2012-09-22 Chong Yidong <cyd@gnu.org>
6474 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6477 2012-09-22 Kenichi Handa <handa@gnu.org>
6479 * composite.c (composition_reseat_it): Handle the case that a
6480 grapheme cluster is not covered by a single font (Bug#12352).
6482 2012-09-21 Chong Yidong <cyd@gnu.org>
6484 * image.c (define_image_type): Avoid adding duplicate types to
6485 image_types (Bug#12463). Suggested by Jörg Walter.
6487 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6489 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6490 (print_load_command_name): Add case LC_DATA_IN_CODE.
6491 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6493 2012-09-21 Glenn Morris <rgm@gnu.org>
6495 * eval.c (Frun_hook_with_args_until_success)
6496 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6498 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6500 * fileio.c (Ffile_selinux_context): Only call freecon when
6501 lgetfilecon succeeded.
6502 (Fset_file_selinux_context): Likewise. (Bug#12444)
6504 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6506 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6507 reordering, locate the cursor by calling set_cursor_from_row; if
6508 that fails, clear the desired glyph matrix before returning a
6509 failure indication to the caller. Fixes leaving garbled display
6510 when fast scrolling with a down-key. (Bug#12403)
6511 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6512 scrolling through multibyte text.
6514 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6516 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6517 calling mark_vectorlike since that's the one that marks the window.
6518 (mark_discard_killed_buffers): Mark the final cdr.
6519 * window.h (struct window): Move prev/next_buffers to the
6520 non-standard fields.
6521 * window.c (make_window): Initialize prev/next_buffers manually.
6523 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6525 Omit unused arg EXPECTED from socket hooks.
6526 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6527 * nsterm.m (ns_term_init):
6528 * termhooks.h (struct terminal.read_socket_hook):
6529 * w32inevt.c (w32_console_read_socket):
6530 * w32term.c (w32_read_socket):
6531 * xterm.c (XTread_socket):
6532 Omit unused arg EXPECTED. All callers changed.
6533 (store_user_signal_events): Return void, not int, since callers no
6534 longer care about the return value. All uses changed.
6536 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6538 * w32gui.h (XParseGeometry): Do not declare.
6540 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6542 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6543 Ignore 'expected'. See Eli Zaretskii in
6544 <http://bugs.gnu.org/12471#8> (last line).
6546 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6547 (XParseGeometry): Now static. Substitute extremal values for
6548 values that are out of range.
6550 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6552 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6554 * nsfns.m (XParseGeometry): Remove.
6555 (Fx_create_frame): Call x_set_offset to correctly interpret
6556 top_pos in geometry.
6558 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6559 (Fx_parse_geometry): If there is a space in string, call
6560 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6562 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6564 * search.c (scan_buffer): Use character positions in calls to
6565 region_cache_forward and region_cache_backward, not byte
6566 positions. (Bug#12196)
6568 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6569 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6571 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6572 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6573 emacs_blocked_malloc, now deleted.
6575 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6577 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6578 The workaround was for improving performance on Solaris 2.4, but
6579 is getting in the way now. Emacs will still work if someone is
6580 still running Solaris 2.4 in a museum somewhere; Sun dropped
6581 support for Solaris 2.4 in 2003.
6582 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6583 * process.c (create_process) [HAVE_WORKING_VFORK]:
6584 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6585 since Emacs no longer uses vfork on that platform.
6587 2012-09-17 Glenn Morris <rgm@gnu.org>
6589 * emacs.c: Use COPYRIGHT.
6591 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6593 Remove configure's --without-sync-input option (Bug#12450).
6594 When auditing signal-handling in preparation for cleaning it up,
6595 I found that SYNC_INPUT has race conditions and would be a real
6596 pain to fix. Since it's an undocumented and deprecated
6597 configure-time option, now seems like a good time to remove it.
6598 Also see <http://bugs.gnu.org/11080#16>.
6599 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6600 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6601 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6602 (malloc_hysteresis):
6603 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6604 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6605 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6606 (dont_register_blocks, bytes_used_when_reconsidered)
6607 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6608 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6609 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6610 Remove. All uses removed.
6611 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6612 implementation, one that depends on whether the new macro
6613 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6615 * atimer.c (run_timers, handle_alarm_signal):
6616 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6617 (handle_async_input, process_pending_signals)
6618 (handle_input_available_signal, init_keyboard):
6619 * nsterm.m (ns_read_socket):
6620 * process.c (wait_reading_process_output):
6621 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6622 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6624 * xterm.c (XTread_socket):
6626 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6627 * eval.c (handling_signal): Remove. All uses removed.
6628 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6629 All uses replaced with the SYNC_INPUT version.
6630 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6632 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6635 * font.c (Ffont_shape_gstring): Remove unused local.
6637 2012-09-16 Glenn Morris <rgm@gnu.org>
6639 * Makefile.in (clean): No longer run nextstep's clean.
6641 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6643 (ns-app): Move here from ns.mk, and simplify.
6644 (clean): Simplify nextstep entry.
6645 * ns.mk: Remove file.
6647 2012-09-17 Kenichi Handa <handa@gnu.org>
6649 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6650 not covert the last few charactes.
6652 2012-09-16 Kenichi Handa <handa@gnu.org>
6654 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6655 here, but just check the validity of glyphs in the glyph-string.
6657 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6659 * window.c (Fwindow_parameter, Fset_window_parameter):
6660 Accept any window as argument (Bug#12452).
6662 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6664 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6665 to ns_term_init to avoid memory leak.
6667 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6668 explicit retain/release.
6669 (ns_term_init): Only allow one display. Initialize outerpool and
6672 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6674 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6675 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6676 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6677 the Microsoft problem in a different way, by altering ../nt/config.nt.
6679 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6694 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6695 by lisp.h. This completes removal of setjmp.h inclusion
6696 erroneously announced in the previous commit. (Bug#12446)
6698 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6701 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6702 not defined as a macro. The latter happens on MS-Windows.
6705 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6707 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6708 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6709 Some instances of '#include <setjmp.h>' removed, if the
6710 only reason for the instance was because "lisp.h" was included.
6711 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6712 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6713 and _longjmp with the new symbols. Emacs already uses _setjmp if
6714 available, so this change affects only POSIXish hosts that have
6715 sigsetjmp but not _setjmp, such as some versions of Solaris and
6716 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6717 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6718 (png_load_body) [HAVE_PNG]:
6719 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6720 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6721 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6722 since PNG requires jmp_buf. This is the only exception to the
6723 general rule that we now use sys_setjmp and sys_longjmp.
6724 This exception is OK since this code does not change the signal
6725 mask or longjmp out of a signal handler.
6727 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6729 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6730 Include "syssignal.h", for 'main_thread'.
6732 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6734 Avoid out-of-range marker position (Bug#12426).
6735 * insdel.c (replace_range, replace_range_2):
6736 Adjust markers before overlays, as suggested by comments.
6737 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6738 Remove redundant check before calling offset_intervals.
6740 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6742 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6743 current buffer (Bug#12387).
6745 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6747 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6749 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6751 Use a more backwards-compatible timer format (Bug#12430).
6752 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6753 vector element, not from the 4th, since PSECS is now at the end.
6754 (Fcurrent_idle_time): Doc fix.
6756 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6758 Function to mark objects and remove killed buffers at once.
6759 * alloc.c (discard_killed_buffers): Rename to ...
6760 (mark_discard_killed buffers) ... new name. Add marking
6761 of remaining objects. Fix comment. Adjust users.
6762 (mark_object): Do not touch frame buffer lists here.
6763 * frame.c (delete_frame): Reset frame buffer lists here.
6765 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6767 Better workaround for GNOME bug when --enable-gcc-warnings.
6768 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6769 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6770 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6772 Simplify SIGIO usage (Bug#12408).
6773 The code that dealt with SIGIO was crufty and confusing, e.g., it
6774 played tricks like "#undef SIGIO" but these tricks were not used
6775 consistently. Simplify mostly by not #undeffing standard symbols,
6776 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6777 or not as we please) rather than "defined SIGIO" (standard symbol
6778 that we probably shouldn't #undef).
6779 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6780 Modules that need it can include it.
6781 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6782 * dispextern.h (ignore_sigio): New decl.
6783 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6784 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6785 * emacs.c (shut_down_emacs):
6786 * keyboard.c (kbd_buffer_store_event_hold):
6787 Use ignore_sigio rather than invoking 'signal' directly.
6788 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6790 (FIONREAD, SIGIO): Do not #undef.
6791 (tty_read_avail_input): Use #error rather than a syntax error.
6792 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6793 for I_PIPE, used by SETUP_SLAVE_PTY.
6794 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6795 * sysdep.c (croak): Remove; no longer needed. This bit of
6796 temporary code, with Fred N. Fish's comment that it's temporary,
6797 has been in Emacs since at least 1992!
6798 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6799 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6800 * syssignal.h (croak): Remove decl.
6801 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6802 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6803 now that we're termios-only.
6804 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6805 * term.c (dissociate_if_controlling_tty): Use #error rather than
6808 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6809 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6810 to work around GNOME bug 683906.
6811 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6812 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6813 This works around GCC bug 54561.
6815 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6817 More fixes for 'volatile' and setjmp/longjmp.
6818 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6819 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6820 (png_load_body) [HAVE_PNG]:
6821 (jpeg_load_body) [HAVE_JPEG]:
6822 New function, with most of the old parent function's body.
6823 (png_load) [HAVE_PNG]:
6824 (jpeg_load) [HAVE_JPEG]:
6825 Invoke the new function, to avoid longjmp munging our locals.
6826 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6827 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6828 longjmp is passed 2, as the C standard doesn't guarantee this.
6829 Instead, store the failure code into mgr->failure_code.
6831 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6833 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6834 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6835 (syms_of_keyboard): Remove support for unread-command-char.
6837 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6839 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6840 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6841 violation. (Bug#12426)
6843 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6845 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6847 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6849 * eval.c: Add `inhibit-debugger'.
6850 (Qinhibit_debugger): New symbol.
6851 (call_debugger): Bind it instead of Qdebug_on_error.
6852 (maybe_call_debugger): Test Vinhibit_debugger.
6853 (syms_of_eval): Define inhibit-debugger.
6854 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6855 (syms_of_xdisp): Remove inhibit-debug-on-message.
6857 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6859 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6860 If a nonvolatile local variable is written before a _longjmp to
6861 the frame containing the variable, and is read after the _longjmp,
6862 the value read is indeterminate. Some local variables of type
6863 'struct handler' and 'struct catchtag' are used in this way, so
6864 mark each of their slots as volatile if the slot can be set before
6865 _longjmp and read afterwards.
6866 * lisp.h (struct handler): var and chosen_clause are now volatile.
6867 (struct catchtag): val, next, and pdlcount are now volatile.
6869 * bidi.c (bidi_push_it, bidi_pop_it):
6870 * fns.c (copy_hash_table):
6871 * image.c (define_image_type):
6872 * keyboard.c (kbd_buffer_store_event_hold):
6873 * process.c (Fprocess_send_eof):
6874 * xfaces.c (x_create_gc) [HAVE_NS]:
6875 * xgselect.c (xg_select):
6876 Prefer assignment to memcpy when either will do.
6878 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6879 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6880 time an item is removed. No need to mark this function 'inline';
6881 the compiler knows better than we do.
6883 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6885 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6886 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6887 to change_frame_size (Bug#12388).
6888 (windowDidResize:): Pass YES to updateFrameSize.
6890 * nsterm.h: Add delay parameter to updateFrameSize.
6892 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6894 Discard killed buffers from deleted window and frame objects.
6895 This reduces an amount of references to killed buffers and
6896 helps GC to reclaim them faster.
6897 * alloc.c (discard_killed_buffers): New function.
6898 (mark_object): Use it for deleted windows and frames.
6899 (mark_object): If symbol's value is set up for a killed buffer
6900 or deleted frame, restore its global binding.
6901 * data.c (swap_in_global_binding): Add GC notice.
6902 (swap_in_symval_forwarding): Use convenient set_blv_where.
6903 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6904 * window.h: ... to here.
6906 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6908 Convenient macro to check whether the buffer is live.
6909 * buffer.h (BUFFER_LIVE_P): New macro.
6910 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6911 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6913 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6915 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6916 composition cases (Bug#12364).
6918 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6919 overhang of succeeding glyphs overlapping box cursor.
6921 * w32term.c (x_draw_glyph_string): Likewise.
6923 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6925 Simplify, document, and port floating-point (Bug#12381).
6926 The porting part of this patch fixes bugs on non-IEEE platforms
6927 with frexp, ldexp, logb.
6928 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6930 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6931 support, by removing commented-out code and briefly listing the
6932 C89 functions excluded. The commented-out stuff was confusing
6933 maintenance, e.g., we thought we needed cbrt but it was commented out.
6934 (logb): Remove decl; no longer needed.
6935 (isfinite): New macro, if not already supplied.
6936 (isnan): Don't replace any existing macro.
6937 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6938 are present on all C89 platforms.
6939 (Ffrexp): Do not special-case zero, as frexp does the right thing
6941 (Flogb): Do not use logb, as it doesn't have the desired meaning
6942 on hosts that use non-base-2 floating point. Instead, stick with
6943 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6944 frexp, to avoid getting an unspecified result.
6946 * xdisp.c (Qinhibit_debug_on_message): Now static.
6948 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6950 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6951 NSBezierPath (Bug#12131).
6953 2012-09-10 Chong Yidong <cyd@gnu.org>
6955 * fns.c (Fdelq, Fdelete): Doc fix.
6957 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6959 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6960 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6962 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6964 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6965 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6968 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6970 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6971 left fringe if the window has a left margin. This avoids leaving
6972 traces of the cursor because its leftmost pixel is not drawn over.
6974 * dispnew.c (update_window_line): When the left margin area of a
6975 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6976 that screen line. (Bug#12277)
6978 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6980 Assume C89 or later for math functions (Bug#12381).
6981 This simplifies the code, and makes it a bit smaller and faster,
6982 and (most important) makes it easier to clean up signal handling
6983 since we can stop worring about floating-point exceptions in
6984 library code. That was a problem before C89, but the problem
6985 went away many years ago on all practical Emacs targets.
6986 * data.c, image.c, lread.c, print.c:
6987 Don't include <math.h>; no longer needed.
6988 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6989 might be autoconfigured, as that never happens.
6991 * doprnt.c (DBL_MAX_10_EXP):
6992 * print.c (DBL_DIG):
6993 Remove. C89 or later always defines these.
6994 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6995 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6996 (arith_error, domain_error, domain_error2):
6997 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6998 no longer needed -- we simply return what C returns. All uses removed.
6999 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
7001 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
7002 Remove. All uses expanded, as these macros are no longer used
7003 more than once and are now more trouble than they're worth.
7004 (Ftan): Use tan, not sin / cos.
7005 (Flogb): Assume C89 frexp.
7006 (fmod_float): Assume C89 fmod.
7007 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
7008 (init_floatfns): Remove. All uses removed.
7010 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7012 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
7013 compositeToPoint for OSX < 10.6 (Bug#12390).
7015 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
7017 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
7018 This produces more-accurate results.
7020 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7022 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
7023 changes (Bug#12088).
7025 2012-09-08 Chong Yidong <cyd@gnu.org>
7027 * syntax.c (Fstring_to_syntax): Doc fix.
7029 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
7031 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
7032 in the internal border.
7033 (x_set_window_size): Remove static variables and their usage.
7034 (ns_redraw_scroll_bars): Fix NSTRACE arg.
7035 (ns_after_update_window_line, ns_draw_fringe_bitmap):
7036 Remove fringe/internal border adjustment (Bug#11052).
7037 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
7038 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
7039 (ns_fix_rect_ibw): Remove.
7040 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
7041 (ns_dumpglyphs_box_or_relief): Ditto.
7042 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
7044 (ns_dumpglyphs_image): Ditto.
7045 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
7047 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
7048 their usage. Add fringe_extended_p and its use as in other terms.
7049 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
7050 scroll bar was removed.
7051 (updateFrameSize): New function.
7052 (windowDidResize): Move code to updateFrameSize and call it.
7054 * nsterm.h (EmacsView): Add updateFrameSize.
7056 2012-09-07 Chong Yidong <cyd@gnu.org>
7058 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
7060 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
7062 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7064 More signal-handler cleanup (Bug#12327).
7065 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
7066 Problem introduced when merging patches. Noted by Eli Zaretskii in
7067 <http://bugs.gnu.org/12327#67>.
7068 * floatfns.c: Comment fix.
7069 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
7070 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
7071 and anyway the declaration is harmless even if SIGDANGER is not defined.
7072 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
7073 defined BROKEN_FIONREAD). systty.h formerly did this, but other
7074 source files not surprisingly expected syssignal.h to define, or
7075 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7076 Include <sys/ioctl.h>, for FIONREAD.
7077 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7078 This eliminates a problem whereby other files mysteriously had
7079 to include "syssignal.h" before including "systty.h" if they
7080 wanted to use "#ifdef SIGIO".
7082 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7084 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7086 * w32.c (sigemptyset): Empty the set.
7087 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7089 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7091 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7093 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7094 (mark_object): Likewise for frame objects.
7096 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7098 * syssignal.h (handle_on_main_thread): Always declare,
7099 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7100 This ports to platforms without HAVE_PTHREAD.
7102 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7104 Signal-handler cleanup (Bug#12327).
7105 Emacs's signal handlers were written in the old 4.2BSD style with
7106 sigblock and sigmask and so forth, and this led to some
7107 inefficiencies and confusion. Rewrite these to use
7108 pthread_sigmask etc. without copying signal sets around. Also,
7109 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7110 'signal', and instead use functions that do not attempt to take
7111 over the system name space. This patch causes Emacs's text
7112 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7113 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7114 Do not include <signal.h> or "syssignal.h", as these
7115 modules do not use signals.
7116 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7117 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7118 Do not include <signal.h>, as "syssignal.h" does that for us now.
7119 * atimer.c (sigmask_atimers): New function.
7120 (block_atimers, unblock_atimers): New functions,
7121 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7123 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7124 no longer needed here.
7125 * emacs.c (main): Inspect existing signal handler with sigaction,
7126 so that there's no need to block and unblock SIGHUP.
7127 * sysdep.c (struct save_signal): New member 'action', replacing
7128 old member 'handler'.
7129 (save_signal_handlers, restore_signal_handlers):
7130 Use sigaction instead of 'signal' to save and restore.
7131 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7132 New function. All users of 'signal' modified to use set_sighandler
7133 if they're writeonly, and to use sys_signal if they're read+write.
7134 (emacs_sigaction_init, forwarded_signal): New functions.
7135 (sys_signal): Remove. All uses replaced by calls to sigaction
7136 and emacs_sigaction_init, or by direct calls to 'signal'.
7137 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7138 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7139 all uses replaced by pthread_sigmask etc. calls.
7140 * syssignal.h: Include <signal.h>.
7141 (emacs_sigaction_init, forwarded_signal): New decls.
7142 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7143 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7144 (sigmask, sys_sigmask): Remove; no longer needed.
7145 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7146 (sigblock, sigunblock, sigfree):
7147 (sigsetmask) [!defined sigsetmask]:
7148 Remove. All uses replaced by pthread_sigmask.
7149 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7150 no longer need to be replaced, and its typical old uses
7151 are now done via emacs_sigaction_init and sigaction.
7152 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7153 (sys_sigdel): Remove; unused.
7154 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7156 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7158 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7159 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7161 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7163 Explicitly mark buffer_defaults and buffer_local_symbols.
7164 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7165 mark_local_symbols here.
7166 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7167 since special buffers aren't marked here any more.
7168 (allocate_buffer): Chain new buffer with all_buffers here...
7169 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7171 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7172 (syms_of_buffer): Remove staticpro of the above.
7173 (init_buffer_once): Set names for buffer_defaults and
7174 buffer_local_symbols.
7176 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7178 Use bool for booleans in font-related modules.
7179 * font.c (font_intern_prop, font_style_to_value)
7180 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7181 (generate_otf_features, font_check_otf_features, font_check_otf)
7182 (font_match_p, font_list_entities, font_at):
7183 * fontset.c (fontset_id_valid_p, reorder_font_vector
7184 (fontset_find_font, Fset_fontset_font)
7185 (face_suitable_for_char_p) [0]:
7186 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7187 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7188 (m17n_flt_initialized, ftfont_shape_by_flt):
7189 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7190 * nsfont.m (nsfont_draw):
7191 * w32font.c (w32font_draw):
7192 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7193 Use bool for booleans.
7194 * font.h: Adjust to above API changes.
7195 (struct font, struct font_driver, struct font_driver_list):
7196 Use bool for booleans.
7197 (struct font): Remove useless member encoding_type.
7199 * fontset.c, xftfont.c: Omit unnecessary static decls.
7201 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7203 * alloc.c (mark_object): Revert window marking code
7204 since it's unsafe for the Fset_window_configuration.
7206 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7208 Fix race conditions with signal handlers and errno (Bug#12327).
7209 Be more systematic about preserving errno whenever a signal
7210 handler returns, even if it's not in the main thread. Do this by
7211 renaming signal handlers to distinguish between signal delivery
7212 and signal handling. All uses changed.
7213 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7214 * data.c (deliver_arith_signal): Rename from arith_error.
7215 * dispnew.c (deliver_window_change_signal): Rename from
7216 window_change_signal.
7217 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7218 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7219 * keyboard.c (deliver_input_available_signal): Rename from
7220 input_available_signal.
7221 (deliver_user_signal): Rename from handle_user_signal.
7222 (deliver_interrupt_signal): Rename from interrupt_signal.
7223 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7224 (deliver_child_signal): Rename from sigchld_handler.
7225 * atimer.c (handle_alarm_signal):
7226 * data.c (handle_arith_signal):
7227 * dispnew.c (handle_window_change_signal):
7228 * emacs.c (handle_fatal_signal, handle_danger_signal):
7229 * keyboard.c (handle_input_available_signal):
7230 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7231 * process.c (handle_pipe_signal, handle_child_signal):
7232 New functions, with the actual signal-handling code taken from the
7233 original respective signal handlers, sans the sporadic attempts to
7234 preserve errno, since that's now done by handle_on_main_thread.
7235 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7236 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7237 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7239 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7240 Move initialization of main_thread to sysdep.c's init_signals.
7241 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7242 our usage, and simplifies the mainline code.
7243 (record_child_status_change): New static function, as a helper
7244 for handle_child_signal, and with most of the old child handler's
7246 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7247 (handle_child_signal): Use the above.
7248 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7249 Moved here from emacs.c.
7250 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7251 code moved here from emacs.c's main function.
7252 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7253 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7254 This lets callers save and restore errno properly.
7256 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7258 Remove redundant or unused things here and there.
7259 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7260 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7261 * editfns.c (Fcompare_buffer_substrings): Likewise.
7262 * frame.h (struct terminal, struct font_driver_list):
7263 Remove redundant declarations.
7264 * window.h (Qleft, Qright): Likewise.
7266 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7268 Do not mark objects from deleted buffers, windows and frames.
7269 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7270 (mark_object): Likewise for windows and frames.
7272 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7274 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7275 buffer_defaults and buffer_local_symbols as valid objects.
7276 Return special value to denote them.
7278 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7280 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7281 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7282 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7283 (file_name_absolute_p, Fsubstitute_in_file_name):
7284 (check_executable, check_writable, Ffile_accessible_directory_p)
7285 (Fset_file_selinux_context, Fdefault_file_modes)
7286 (Finsert_file_contents, choose_write_coding_system)
7287 (Fwrite_region, build_annotations, a_write, e_write)
7289 * filelock.c (boot_time_initialized, get_boot_time)
7290 (get_boot_time_1, lock_file_1, within_one_second):
7291 * floatfns.c (in_float):
7292 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7293 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7294 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7295 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7296 * window.c (compare_window_configurations):
7297 Use bool for booleans.
7298 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7299 (Fdefault_file_modes): Now mode_t, not int, for modes.
7300 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7301 (internal_delete_file): Now returns void, not a (boolean) int,
7302 since nobody was looking at the return value.
7303 * lisp.h, window.h: Adjust to above API changes.
7305 * xdisp.c (set_message): Simplify and reindent last change.
7307 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7309 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7311 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7313 * eval.c (call_debugger): Make the function non-static so that we
7314 can call it from set_message.
7316 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7317 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7319 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7321 Give more-useful info on a fatal error (Bug#12328).
7322 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7323 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7324 of doing the work ourselves.
7325 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7326 do most of the work.
7327 (fatal_error_backtrace): New function, taken from the guts
7328 of the old fatal_error_signal, but with a new option to output
7330 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7331 info about the signal than just its number.
7332 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7333 * sysdep.c: Include <execinfo.h>
7334 (emacs_backtrace): New function, taken partly from the previous
7335 code of the 'die' function.
7336 (emacs_abort): Call fatal_error_backtrace rather than abort.
7338 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7340 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7341 eager (load-time) macro-expansion.
7342 * lisp.mk (lisp): Add macroexp.
7344 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7346 Simplify redefinition of 'abort' (Bug#12316).
7347 Do not try to redefine the 'abort' function. Instead, redo
7348 the code so that it calls 'emacs_abort' rather than 'abort'.
7349 This removes the need for the NO_ABORT configure-time macro
7350 and makes it easier to change the abort code to do a backtrace.
7351 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7352 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7353 Remove; sysdep.c's emacs_abort now takes its place.
7354 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7355 'abort' changed to use 'emacs_abort'.
7356 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7357 (abort) [!defined abort]: Rename to ...
7358 (emacs_abort): ... new name.
7359 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7360 the place of the old 'abort' in emacs.c.
7361 * w32.c, w32fns.c (abort): Do not #undef.
7362 * w32.c (emacs_abort): Rename from w32_abort.
7364 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7366 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7367 offsets[j].dv, since the y axis of the screen coordinates points
7368 down, while the y axis of the font definition coordinates points
7369 up. This fixes display of Arabic diacritics such as KASRA and
7370 KASRATAN. (Bug#11860)
7372 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7374 Be more systematic about _setjmp vs setjmp.
7375 * alloc.c (test_setjmp, mark_stack):
7376 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7377 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7378 (png_load, my_error_exit, jpeg_load):
7379 * process.c (send_process_trap, send_process):
7380 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7381 The underscored versions are up to 30x faster on some hosts.
7382 Formerly, the code used setjmp+longjmp sometimes and
7383 _setjmp+_longjmp at other times, with no particular reason to
7384 prefer setjmp+longjmp.
7386 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7388 Fix minor problem found by static checking.
7389 * buffer.c (Fdelete_all_overlays): Return nil.
7391 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7393 * buffer.c (Fdelete_all_overlays): New function.
7395 2012-09-03 Chong Yidong <cyd@gnu.org>
7397 * gtkutil.c: Add extern decl for Qxft.
7399 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>

7413 All callers changed.
7414 * eval.c (interactive_p): Omit always-true boolean argument
7415 EXCLUDE_SUBRS_P. All callers changed.
7416 * dispextern.h, lisp.h: Reflect above API changes.
7417 * firstfile.c (dummy): Use the address of 'main', whose signature
7418 won't change, instead of the address of 'initialize', whose
7419 signature just changed from int to bool.
7420 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7421 * msdos.c (fatal_error_in_progress): ... from here.
7422 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7424 (redisplay_internal, unwind_redisplay): Simply clear
7425 REDISPLAYING_P when unwinding, instead of saving its previous,
7426 always-false value and then restoring it.
7428 Clean up some extern decls.
7429 Mostly, this hoists extern decls out of .c files and into .h files.
7430 That way, we're more likely to catch errors if the interfaces change.
7431 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7432 declare xg_mark_data.
7433 * dispextern.h (x_frame_parm_handlers):
7435 * lisp.h (Qlexical_binding, Qinternal_interpreter_environment)

7449 * widget.c (free_frame_faces):
7450 * xfaces.c (free_frame_menubar) [USE_X_TOOLKIT]:
7451 * xfont.c (x_clear_errors):
7452 * xterm.c (x_frame_parm_handlers):
7453 Remove now-redundant extern decls.
7454 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
7455 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
7457 * xfaces.c: Remove unnecessary static decls.
7458 * xterm.c (updating_frame): Remove decl of nonexistent object.
7460 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7461 when building globals.h, as the objects that are not built on
7462 this host are not needed to compile C files on this host.
7464 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
7466 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

7480 (make_buffer_string, make_buffer_string_both)
7481 (Fsubst_char_in_region, Ftranslate_region_internal, Fformat):

7493 (set_intervals_multibyte_1, set_intervals_multibyte):
7494 * keyboard.c (decode_timer):
7495 Use bool for boolean.
7496 * intervals.h, lisp.h, systime.h: Reflect above API changes.
7497 * editfns.c (struct info): Use 1-bit unsigned bitfields for booleans.

7504 2012-09-02 Juanma Barranquero <lekktu@gmail.com>
7506 * makefile.w32-in (CCL_H, W32FONT_H): New macros.
7507 (ATIMER_H, FONT_H, $(BLD)/alloc.$(O), $(BLD)/callproc.$(O))

7514 2012-09-01 Eli Zaretskii <eliz@gnu.org>
7516 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7517 more than one grapheme cluster passed to the shaper: compute the
7518 offset adjustment values separately for each cluster. (Bug#11860)
7520 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7521 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7522 about implicit conversions from integer to pointer.
7524 2012-09-01 Daniel Colascione <dancol@dancol.org>
7526 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7527 system used too early.
7529 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>
7531 Better seed support for (random).

7572 * keyboard.c: Include TERM_HEADER instead of listing all possible
7573 window-system headers.

7576 window-system headers. Declare Vlibrary_cache when compiling for
7579 * gtkutil.h (xg_list_node_): Include xterm.h to pick up needed
7580 window system declarations.
7582 * frame.h: Move common functions here: set_frame_menubar,
7583 x_set_window_size, x_sync, x_get_focus_frame,
7584 x_set_mouse_position, x_set_mouse_pixel_position,
7585 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7609 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>
7611 Remove mark_ttys function and fix tty_display_info initialization.
7612 * lisp.h (mark_ttys): Remove prototype.
7613 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call
7614 to mark_ttys because all possible values of 'top_frame' slot are
7615 the frames which are reachable from Vframe_list.
7616 * term.c (mark_ttys): Remove.
7617 (init_tty): Safely initialize 'top_frame' slot with Qnil.
7619 2012-08-31 Dmitry Antipov <dmantipov@yandex.ru>

7624 'auto_raise', 'auto_lower', 'no_split', 'explicit_name',
7625 'window_sizes_changed', 'mouse_moved' and 'pointer_invisible'
7626 bitfields from unsigned char to unsigned.

7642 for GCC 4.7.1 x86-64.
7644 2012-08-30 Glenn Morris <rgm@gnu.org>
7646 * lread.c (init_lread): For out-of-tree builds, only add the
7647 source directory's site-lisp dir to the load-path if it exists,
7648 consistent with in-tree builds. (Bug#12302)
7650 2012-08-28 Jan Djärv <jan.h.d@swipnet.se>
7652 * nsmenu.m (initWithContentRect:styleMask:backing:defer:): Initialize

7662 (addSplit): Remove return self, declare return value as void.
7663 (clicked:): Remove return self, declare return value as void.
7664 Set dialog_return to button_values[seltag]. Code formatting change.

7666 Code formatting change.
7667 (timeout_handler:): Set timer_fired to YES.
7668 (runDialogAt:): Set timer_fired to NO.
7669 Handle click on close button as quit.
7671 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7672 Add window_closed and button_values. Add void as return value for
7673 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7674 Add process_dialog as new member.
7676 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7678 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

7756 2012-08-27 Jan Djärv <jan.h.d@swipnet.se>
7758 * nsterm.h (NSPanel): New class variable dialog_return.
7760 * nsmenu.m (initWithContentRect:styleMask:backing:defer:):
7761 Initialize dialog_return.
7762 (windowShouldClose:): Use stop instead of stopModalWithCode.
7763 (clicked:): Ditto, and also set dialog_return (Bug#12258).
7764 (timeout_handler:): Use stop instead of abortModal. Send a dummy
7766 (runDialogAt:): Make ret Lisp_Object. Set it from dialog_return when
7769 2012-08-27 Paul Eggert <eggert@cs.ucla.edu>
7771 * composite.c, data.c, dbusbind.c, dired.c: Use bool for booleans.
7772 * composite.c (find_composition, composition_gstring_p)
7773 (composition_reseat_it, find_automatic_composition):
7774 * data.c (let_shadows_buffer_binding_p)
7775 (let_shadows_global_binding_p, set_internal, make_blv)
7776 (Fmake_variable_buffer_local, Fmake_local_variable)
7777 (Fmake_variable_frame_local, arithcompare, cons_to_unsigned)
7778 (cons_to_signed, arith_driver):
7779 * dbusbind.c (xd_in_read_queued_messages):
7780 * dired.c (directory_files_internal, file_name_completion):
7781 Use bool for booleans.
7782 * dired.c (file_name_completion):
7783 * process.h (fd_callback):
7784 Omit int (actually boolean) argument. It wasn't being used.
7786 * composite.h, lisp.h: Reflect above API changes.
7788 * cmds.c, coding.c: Use bool for booleans.
7789 * cmds.c (move_point, Fself_insert_command):
7790 * coding.h (struct composition status, struct coding_system):
7791 * coding.c (detect_coding_utf_8, encode_coding_utf_8)
7792 (detect_coding_utf_16, encode_coding_utf_16, detect_coding_emacs_mule)
7793 (emacs_mule_char, decode_coding_emacs_mule)
7794 (encode_coding_emacs_mule, detect_coding_iso_2022)
7795 (decode_coding_iso_2022, encode_invocation_designation)
7796 (encode_designation_at_bol, encode_coding_iso_2022)
7797 (detect_coding_sjis, detect_coding_big5, decode_coding_sjis)
7798 (decode_coding_big5, encode_coding_sjis, encode_coding_big5)
7799 (detect_coding_ccl, encode_coding_ccl, decode_coding_raw_text)
7800 (encode_coding_raw_text, detect_coding_charset)
7801 (decode_coding_charset, encode_coding_charset, detect_eol)

7806 (detect_coding_system, char_encodable_p)
7807 (Funencodable_char_position, code_convert_region)
7808 (code_convert_string, code_convert_string_norecord)
7809 (Fset_coding_system_priority):
7810 * fileio.c (Finsert_file_contents):
7811 Use bool for booleans.
7812 * coding.h, lisp.h: Reflect above API changes.
7813 * coding.c: Remove unnecessary static function decls.
7814 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7815 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7816 not a boolean 'int', since callers never look at the return value.
7817 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
7818 * coding.h (decoding_buffer_size, encoding_buffer_size)
7819 (emacs_mule_string_char): Remove unused extern decls.
7820 (struct iso_2022_spec, struct coding_system):
7821 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7822 (struct emacs_mule_spec): Remove unused field 'full_support'.
7823 All initializations removed.
7824 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7826 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7828 Fix spare memory change (Bug#12286).
7829 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7830 (valid_lisp_object_p): Likewise.
7832 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7834 * window.c (Fset_window_configuration): Record any window's old
7835 buffer if it's replaced (see Bug#8789). If the new current
7836 buffer doesn't appear in the selected window, go to its old
7839 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7841 Special MEM_TYPE_SPARE to denote reserved memory.
7842 * alloc.c (enum mem_type): New memory type.
7843 (refill_memory_reserve): Use new type for spare memory.
7844 This prevents live_cons_p and live_string_p from incorrect
7845 detection of uninitialized objects from spare memory as live.
7847 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7850 * Makefile.in (.PHONY): versioclean -> versionclean.
7852 Remove unused external symbols.
7853 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7854 * window.c (Qwindow_valid_p, decode_valid_window):
7855 Now static, not extern.
7856 * data.c (Qinterval): Remove; unused.
7857 (syms_of_data): Do not define 'interval'.
7858 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7859 * window.h (decode_valid_window):
7862 * character.c, charset.c, chartab.c: Use bool for booleans.
7863 * character.c (lisp_string_width, string_count_byte8)
7864 (string_escape_byte8):
7865 * charset.c (charset_map_loaded, load_charset_map, read_hex):
7866 (load_charset_map_from_file, map_charset_chars)
7867 (Fdefine_charset_internal, define_charset_internal)
7868 (Fdeclare_equiv_charset, find_charsets_in_text)
7869 (Ffind_charset_region, char_charset, Fiso_charset):
7870 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
7871 (sub_char_table_set, sub_char_table_set_range)
7872 (char_table_set_range, optimize_sub_char_table)
7873 (map_sub_char_table):
7874 Use bool for boolean.
7875 * character.c (str_to_unibyte): Omit last boolean argument; it was
7876 always 0. All callers changed.
7877 * character.h, charset.h: Adjust to match previous changes.
7878 * character.h (char_printable_p): Remove decl of nonexistent function.
7879 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7880 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7881 are all boolean, so make them single-bit bitfields.
7883 * lisp.h (ASET): Remove attempt to detect side effects.
7884 It was meant to be temporary and it often doesn't work,
7885 because when IDX has side effects the behavior of IDX==IDX
7886 is undefined. See Stefan Monnier in
7887 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7889 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7891 * lisp.h (functionp): New function (extracted from Ffunctionp).
7892 (FUNCTIONP): Use it.
7893 * eval.c (Ffunctionp): Use it.
7895 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7897 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7898 as that's faster and simpler than static storage. Don't bother
7899 with the g_main_context_query overhead if g_main_context_pending
7900 says no events are pending.
7901 (gfds, gfds_size): Remove these static vars.
7902 (xgselect_initialize): Remove; no longer needed.
7903 All uses and decls removed.
7905 * emacs.c (fatal_error_signal_hook): Remove.
7906 All uses removed. This leftover from old code was always 0.
7908 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7909 * casefiddle.c (casify_object, casify_region):
7910 * casetab.c (set_case_table):
7911 * category.c, category.h (word_boundary_p):
7912 * category.h (CHAR_HAS_CATEGORY):
7913 Use bool for booleans, instead of int.
7915 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7917 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7919 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7921 On assertion failure, print backtrace if available.
7922 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7923 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7924 * Makefile.in (LIB_EXECINFO): New macro.
7927 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7928 * bytecode.c (exec_byte_code):
7929 * callint.c (check_mark, Fcall_interactively):
7930 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7931 (getenv_internal, sync_process_alive, call_process_exited):
7932 * lisp.h (USE_SAFE_ALLOCA):
7933 Use bool for booleans, instead of int.
7934 * lisp.h, process.h: Adjust prototypes to match above changes.
7935 * callint.c (Fcall_interactively): Don't assume the mark's
7936 offset fits in 'int'.
7938 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7940 * buffer.c, buffer.h: Use bool for boolean.
7941 * buffer.c (reset_buffer_local_variables)
7942 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7943 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7944 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7945 (overlay_touches_p, overlay_strings, Foverlay_put)
7946 (report_overlay_modification, call_overlay_mod_hooks):
7947 (mmap_enlarge, mmap_set_vars):
7948 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7949 Use bool for booleans, instead of int.
7950 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7951 since the 1-or-0 return value is always ignored anyway.
7952 (mmap_initialized_p):
7953 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7954 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7956 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7958 * bidi.c: Use bool for boolean.
7959 This is a bit more readable, and makes the text segment of bidi.o
7960 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7961 Presumably it's faster too.
7962 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7964 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7965 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7966 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7967 (bidi_explicit_dir_char, bidi_level_of_next_char)
7968 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7969 Use bool for booleans, instead of int.
7970 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7971 (bidi_unshelve_cache): Adjust decls to match code.
7973 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7975 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7978 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7980 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7981 * atimer.h: Include <stdbool.h>.
7983 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7985 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7986 compile time tests instead of run time tests on systems that do
7988 (FRAME_MAC_P): Remove leftover from deleted code.
7989 * frame.c (syms_of_frame): Remove leftover from deleted code.
7991 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7993 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7995 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7997 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7998 Otherwise, the compiler complains about (A?B:C) where B is void
7999 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
8000 (fontset_add): Return void, for FONTSET_ADD.
8002 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8004 * alloc.c: Use bool for booleans.
8005 (gc_in_progress, abort_on_gc)
8006 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8007 (dont_register_blocks) [GC_MALLOC_CHECK]:
8008 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
8009 (check_string_bytes, make_specified_string, memory_full)
8010 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
8011 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
8012 (mark_stack, valid_pointer_p, make_pure_string)
8013 (Fgarbage_collect, survives_gc_p, gc_sweep):
8014 Use bool for booleans, instead of int.
8015 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
8016 Remove unused local.
8017 * alloc.c (PURE_POINTER_P):
8018 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
8019 * editfns.c (Fformat):
8020 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
8022 * fns.c (sweep_weak_table):
8023 * lisp.h (suppress_checking, push_message, survives_gc_p)
8024 (make_pure_string, gc_in_progress, abort_on_gc):
8025 * lread.c (readchar, read1):
8026 * print.c (Fprin1_to_string):
8027 * xdisp.c (push_message):
8028 Use bool for booleans affected directly or indirectly by
8031 Make recently-introduced setters macros.
8032 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
8033 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
8034 (set_fontset_default, set_fontset_fallback): Rename from their
8035 upper-case counterparts, and make them functions rather than macros.
8036 This is more consistent with the other recently-introduced setters.
8037 These don't need to be inline, since they're local.
8039 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
8041 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
8042 the loop (Bug#12247).
8044 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8046 * lisp.h (vcopy): Use memcpy rather than our own loop.
8047 This fixes a performance regression introduced by the recent
8048 addition of vcopy. This means 'vcopy' will need to be modified
8049 for a copying collector, but that's OK. Also, tighten the
8050 checking in the assertion.
8052 2012-08-21 Eli Zaretskii <eliz@gnu.org>
8054 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
8055 components for RTL text (Bug#11860). Adjust X-OFFSET of each
8056 non-base glyph for the width of the base character, according to
8057 what x_draw_composite_glyph_string_foreground expects.
8058 Generate WADJUST value according to composition_gstring_width's
8059 expectations, to produce correct width of the composed character.
8060 Reverse the sign of the DU offset produced by ScriptPlace.
8062 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
8064 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
8066 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8068 Avoid direct writes to contents member of struct Lisp_Vector.
8069 * lisp.h (vcopy): New function to copy data into vector.
8070 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
8071 * fns.c (Ffillarray): Use ASET.
8072 * keyboard.c (timer_check_2): Use AREF and ASET.
8073 (append_tool_bar_item, Frecent_keys): Use vcopy.
8074 * lread.c (read_vector): Use ASET.
8075 * msdos.c (Frecent_doskeys): Use vcopy.
8076 * xface.c (Finternal_copy_lisp_face): Use vcopy.
8077 (Finternal_merge_in_global_face): Use ASET and vcopy.
8078 * xfont.c (xfont_list_pattern): Likewise.
8080 2012-08-21 Martin Rudalics <rudalics@gmx.at>
8082 * window.c (Fwindow_point): For the selected window always return
8083 the position of its buffer's point.
8084 (Fset_window_point): For the selected window always go in its
8085 buffer to the specified position.
8087 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8089 Setter macros for fontsets.
8090 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8091 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8092 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8095 2012-08-20 Glenn Morris <rgm@gnu.org>
8097 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8098 Don't assume that `ln -f' works.
8100 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8102 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8103 and later about non-assignments with no effect. See discussion at
8104 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8107 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8109 Inline setter functions for Lisp_Objects slots of struct specbinding.
8110 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8113 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8115 * window.c (select_window): Always make selected window's buffer
8118 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8120 Use AREF and ASET for docstrings of category tables.
8121 * category.h (CATEGORY_DOCSTRING): Use AREF.
8122 (SET_CATEGORY_DOCSTRING): Use ASET.
8123 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8125 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8127 Inline setter functions for hash table members.
8128 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8129 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8130 (set_hash_key_and_value, set_hash_index, set_hash_next)
8131 (set_hash_hash): New functions.
8132 * charset.c, fns.c: Adjust users.
8134 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8136 Inline getter and setter functions for per-buffer values.
8137 * buffer.h (per_buffer_default, set_per_buffer_default)
8138 (per_buffer_value, set_per_buffer_value): New functions.
8139 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8140 * buffer.c, data.c: Adjust users.
8142 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8144 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8146 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8148 Rely on <config.h> + <unistd.h> to declare 'environ',
8149 as gnulib does this if the system doesn't.
8150 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8151 Remove declaration. MS-Windows declares it on stdlib.h which is
8152 included by conf_post.h.
8153 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8154 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8155 * vm-limit.c: Include <unistd.h>, for 'environ'.
8157 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8158 (start_of_data): Remove decl; mem-limits.h provides it.
8160 * xdisp.c (handle_invisible_prop): Make it a bit faster
8161 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8163 2012-08-19 Chong Yidong <cyd@gnu.org>
8165 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8168 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
8170 * .gdbinit: Use call instead of set when calling a function in the
8173 * data.c (set_internal): Don't use set_blv_found.
8174 (Fkill_local_variable): Likewise.
8176 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8178 * nsfont.m (ns_ascii_average_width): Ensure the string
8179 ascii_printable is initialized with a null-terminated character
8180 array. Otherwise, it can contain undesired extra characters.
8182 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8184 port new setting code to Sun C 5.8 2005/10/13
8185 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8186 Return void, not Lisp_Object. Otherwise, the compiler
8187 complains about (A?B:C) where B is void and C is Lisp_Object
8188 when compiling CHAR_TABLE_SET, due to the recent change to
8189 the API of sub_char_table_set_contents.
8191 2012-08-18 Chong Yidong <cyd@gnu.org>
8193 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
8194 for the string case (Bug#3874).
8196 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8198 * buffer.h (BSET): Remove (Bug#12215).

8574 Use bool, not int, for Lisp booleans.

9077 Remove unnecessary pointer casts.
9078 * alloc.c (record_xmalloc): New function.
9079 * lisp.h (record_xmalloc): New decl.
9080 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
9081 more like a function. This is because the pointer cast is not
9082 needed. All uses changed.
9083 * print.c (print_string, print_error_message): Avoid length recalc.
9085 Improve fix for macroexp crash with debugging (Bug#12118).
9086 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
9087 ARRAY_MARK_FLAG when checking subscripts, because ASET is
9088 not supposed to be invoked from the garbage collector.
9089 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
9090 (gc_aset): New function, which is like ASET but can be
9091 used in the garbage collector.

9120 with addition of handling of symlinks and support for 'lstat'.
9121 If possible, get file's attributes and security information by
9122 handle, not by name. Produce S_IFLNK bit for symlinks, when
9123 called from 'lstat'.
9124 (stat, lstat): New functions, call 'stat_worker'.
9125 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9126 symlinks when the underlying filesystem supports them.
9128 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9130 Fix macroexp crash on Windows with debugging (Bug#12118).
9131 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9132 checking subscripts; problem introduced with the recent
9133 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9134 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9135 since it's used in non-static inline functions now.
9137 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9138 Don't assume buffer size fits in 'int'. Remove unused local.

9152 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
9153 * alloc.c (LISP_INLINE):

9155 * category.c (CATEGORY_INLINE):
9156 * character.c (CHARACTER_INLINE):
9157 * charset.c (CHARSET_INLINE):
9158 * composite.c (COMPOSITE_INLINE):
9159 * dispnew.c (DISPEXTERN_INLINE):
9160 * sysdep.c (SYSTIME_INLINE):
9161 Define to EXTERN_INLINE, so that the corresponding functions
9162 are compiled into code.

9164 (INLINE_HEADER_END): New macros.
9165 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9185 hard-coding the path separator.
9187 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9189 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9190 This how ASET and AREF are supposed to work, and makes
9191 it easier to think about future improvements. See
9192 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
9193 * charset.h (set_charset_attr): New function.

9575 (w32_kbd_patch_key, key_event): Use the codepage returned by
9576 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.

9608 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9609 enumeration constants, as PURE and HEAP are too general, and clash
9610 with other headers and sources, such as gmalloc.c and the
9611 MS-Windows system headers. All users changed.
9613 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9615 Revert last save_excursion_save and save_excursion_restore changes.
9616 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9629 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9630 arms of an 'if', not using conditional expressions; otherwise GDB
9631 complains about the types in the unevaluated arm when the argument
9632 is an integer literal.
9633 (xgetint): Simplify expression.
9634 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9635 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9636 Zaretskii in <http://bugs.gnu.org/12036#13>.
9637 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9638 needed now that we have gdb_make_enums_visible.
9639 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9640 (enum enum_USE_LSB_TAG):
9641 New enum types, packaging up enums that need to be exported to GDB.

9683 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9684 emacs.c, as this is a more-suitable home. Had this been done earlier
9685 the fix for 12036 would have avoided some of the problems noted in
9686 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9687 would have been more obvious.
9688 * emacs.c: Do not include <verify.h>; no longer needed.
9689 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9690 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9691 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

9696 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9697 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9698 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9699 not be usable in #if. This simplifies things.
9701 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9703 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.

9708 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9709 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9710 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9711 Adjust to changes in lisp.h and emacs.c, by using
9712 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9713 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9714 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9715 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9716 instead of gdb_valbits.
9717 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9718 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9719 instead of gdb_array_mark_flag.
9720 (xboolvector): Get size from $->size, not $->header.size.
9721 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9722 (xreload, hook-run, hookpost-run): Remove.
9723 * emacs.c: Include <verify.h>.
9724 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9725 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9727 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9728 (gdb_USE_LSB_TAG): New enum constants.
9729 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9730 Also define these as enum constants, so they're visible to GDB.
9731 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9732 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9733 as constants, so they're visible to GDB.

9736 Now enum constants, not macros, so they're visible to GDB.
9737 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9738 more convenient now. All uses changed.
9739 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9740 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9742 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9749 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9750 add argument, tune behavior, and adjust all callers.
9752 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9754 Use typedef for EMACS_INT, EMACS_UINT.
9755 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9756 than macros. This simplifies debugging in the usual case, since
9757 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9758 and it allows expressions involving EMACS_INT casts.
9759 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9761 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9771 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9773 Adjust buffer text indirection counters at the end of Fkill_buffer.
9774 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9775 buffer is definitely dead. This should really fix an issue reported
9776 by Christoph Scholtes again. (Bug#12007).
9777 (init_buffer_once): Initialize indirection counters of
9778 buffer_defaults and buffer_local_symbols (for sanity and safety).
9780 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9782 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9783 and continuation glyphs on tooltip frames, leave them at zero.

9811 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9813 Swap buffer text indirection counters in Fbuffer_swap_text.
9814 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9815 This avoids crash reported by Christoph Scholtes at
9816 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9818 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9820 * nsmenu.m (Popdown_data): New struct.
9821 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9823 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9824 (initWithContentRect): Make imgView and contentView non-static
9825 and autorelease them. Also autorelease img and matrix (Bug#12005).
9826 (dealloc): Remove (Bug#12005).
9828 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9830 Adjust consing_since_gc when objects are explicitly freed.

9843 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9845 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9846 as it's limited by the amount of memory, not by INT_MAX.
9848 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9850 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9851 in special-event-map. See the discussion at

9910 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
9911 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
9912 Adjust users accordingly.
9913 * font.h (font_open_by_name): Adjust prototype.
9915 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

9932 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
9933 'for_each_per_buffer_object_at'.
9934 All uses changed. It's better to use upper-case for macros that

9936 that they're special.
9938 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
9940 * alloc.c (Fgarbage_collect): Tweak docstring.

10393 when the right fringe is turned off and variable-size fonts are
10394 used in the window. Move the code that appends a stretch glyph to
10395 produce_special_glyphs, so that it could be used for truncation
10396 and continuation glyphs alike.
10397 (produce_special_glyphs) [HAVE_WINDOW_SYSTEM]: Produce a stretch
10398 glyph of a suitably computed width, to align the special glyphs at
10399 the window margin. Code moved from display_line. (Bug#11832)

10576 EMACS_TIME simplification (Bug#11875).
10577 This replaces macros (which typically do not work in GDB)
10578 with functions, typedefs and enums, making the code easier to debug.
10579 The functional style also makes code easier to read and maintain.
10580 * systime.h: Include <sys/time.h> on all hosts, not just if
10581 WINDOWSNT, since 'struct timeval' is needed in general.
10582 (EMACS_TIME): Now a typedef, not a macro.

10597 (add_emacs_time, sub_emacs_time): New functions.
10598 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

10616 (menu_separator_name_p):
10617 * nsmenu.m (ns_update_menubar):
10618 Prefer memcmp to strncmp when either will do.
10619 * nsterm.m: Include <ftoastr.h>.
10621 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10622 Prefer snprintf to strncpy.
10623 * nsterm.m (ns_term_init):
10624 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10625 * nsterm.m (ns_term_init):
10626 Avoid the need for strncpy, by using build_string or
10627 make_unibyte_string directly. Use dtoastr, not snprintf.
10628 * process.c (Fmake_network_process): Diagnose service names that
10629 are too long, rather than silently truncating them or creating
10630 non-null-terminated names.
10631 (Fnetwork_interface_info): Likewise, for interface names.
10632 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10633 Prefer sprintf to strncat.
10634 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

10646 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10647 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR

10665 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10666 argument, adjust users accordingly. Use build_pure_c_string where

10669 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10670 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

10702 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10703 O_RDONLY already includes it).
10705 Stop ns builds setting the EMACSLOADPATH environment variable.

10707 Now it does not set EMACSLOADPATH, just returns the load-path string.
10708 * nsterm.h: Update accordingly.
10709 * lread.c [HAVE_NS]: Include nsterm.h.
10710 (init_lread) [HAVE_NS]: Use ns_load_path.

10720 (ns_init_paths): Do not set EMACSPATH.

10780 Move marker debugging code under MARKER_DEBUG.
10781 * marker.c (MARKER_DEBUG): Move marker debugging code under
10782 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10783 for bootstrap with --enable-checking (~3x slowdown reported

10819 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10820 (x_set_font) [!HAVE_X_WINDOWS]:
10821 * image.c (xpm_load_image) [HAVE_NS]:
10822 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10823 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10824 Remove unused local.
10825 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10826 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10827 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10828 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10829 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10830 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10831 Fix pointer signedness problem.
10832 * xfaces.c (FRAME_X_FONT_TABLE):
10833 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10835 2012-07-07 Glenn Morris <rgm@gnu.org>
10837 * lread.c (load_path_check): New function, split from init_lread.
10838 (init_lread): Reorganize. Motivation:
10839 If EMACSLOADPATH is set, check/warn about that rather than the
10840 defaults, which we are not going to use. Hence we can remove
10841 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10842 Don't warn if site-lisp directories are missing.
10843 If not installed, start from a blank load-path, since
10844 PATH_LOADSEARCH refers to the eventual installation directories.
10846 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10848 Support truncation and continuation glyphs on GUI frames, when
10849 fringes are disabled. (Bug#11832)
10850 * xdisp.c (init_iterator): Get dimensions of truncation and
10851 continuation glyphs even if on GUI frames.
10852 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10853 or both, are absent.
10854 (start_display, move_it_in_display_line_to): Handle the case of a
10855 GUI frame without a fringe to display continuation or truncation
10857 (insert_left_trunc_glyphs): Support GUI frames: make sure
10858 truncation glyphs overwrite enough glyphs from the current line to
10859 have sufficient space in pixels.
10860 (display_line): Support truncation and continuation glyphs on GUI
10861 frames. If some spare pixels are left on the line after inserting
10862 the truncation glyphs, fill that space with a stretch glyph of a
10863 suitably computed width.
10865 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10866 produce_glyphs, to support GUI sessions.
10868 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10870 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10872 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10874 Do not require float-time's arg to fit in time_t (Bug#11825).
10875 This works better on hosts where time_t is unsigned, and where
10876 float-time is applied to the (negative) difference between two times.
10877 * editfns.c (decode_time_components): Last arg is now double *,
10878 not int *, and means to store all the result as a double, without
10879 worrying about whether the seconds part fits in time_t.
10880 All callers changed.
10881 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10882 All callers changed.
10883 (Ffloat_time): Do not fail merely because the specified time falls
10884 outside of time_t range.
10886 2012-07-07 Glenn Morris <rgm@gnu.org>
10888 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10889 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10890 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10892 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10894 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10895 Update dependencies.
10897 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10899 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>

10903 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10904 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10905 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10906 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10908 * xfont.c (compare_font_names): Redo to omit the need for casts.
10910 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10912 * xfns.c (Fx_change_window_property): Doc fix.
10913 * w32fns.c (Fx_change_window_property): Doc fix.
10915 * w32fns.c (Fx_window_property): Accept the same arguments as the
10916 X Windows version. Doc fix.
10917 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10919 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10920 Eli Zaretskii <eliz@gnu.org>
10922 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10923 Windows-specific code from nt/config.nt moved here.
10924 Obsolete settings removed.
10926 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10928 * process.c: Avoid unnecessary calls to gettime.
10929 (wait_reading_process_output): Don't get the time of day
10930 when gobbling data immediately and not waiting, as there's no need
10931 for it in that case. This removes a FIXME.
10933 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10935 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10936 is defined (Bug#11768).
10938 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10940 Fix marker debugging code.
10941 * marker.c (byte_char_debug_check): Do not perform the check
10942 if buffer is not multibyte.
10943 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10944 Call byte_char_debug_check with correct arguments.
10946 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10948 Compile marker debugging code only if ENABLE_CHECKING is defined.
10949 * marker.c (byte_char_debug_check, count_markers):
10950 Use only if ENABLE_CHECKING is defined.
10951 (byte_debug_flag): Remove.
10952 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10953 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
10955 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10957 Avoid code repetition in marker-related functions.
10958 * marker.c (attach_marker): New function.
10959 (Fset_marker, set_marker_restricted, set_marker_both)
10960 (set_marker_restricted_both): Use it.
10961 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
10962 Consistently rename charno to charpos.
10963 (marker_position): Add eassert.
10964 (marker_byte_position): Convert to eassert.
10966 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10968 Simplify list operations in unchain_overlay and unchain_marker.
10969 * buffer.c (unchain_overlay): Simplify. Add comment.
10970 * marker.c (unchain_marker): Simplify. Fix comments.
10972 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

10977 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
10978 * composite.c (autocmp_chars): Likewise.
10979 * editfns.c (buildmark): Remove.
10980 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
10981 (save_restriction_save): Use build_marker.
10982 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
10983 * window.c (save_window_save): Likewise.
10985 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10987 Do not use Fdelete_overlay in delete_all_overlays
10988 to avoid redundant calls to unchain_overlay.
10989 * buffer.c (drop_overlay): New function.
10990 (delete_all_overlays, Fdelete_overlay): Use it.
10991 * minibuf.c (get_minibuffer): Fix comment.
10993 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10995 Port to OpenBSD 5.1 amd64.
10996 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10997 This is needed for OpenBSD, and should be harmless on all BSD systems.
10998 Also, include <sys/sysctl.h>, as it should be available on all
10999 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
11000 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
11001 use p_pid member, not kp_proc.pid.
11003 2012-07-06 Glenn Morris <rgm@gnu.org>
11005 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
11007 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11009 More xmalloc and related cleanup.
11010 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
11011 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
11012 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

11018 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
11020 Omit needless casts involving void * pointers and allocation.
11021 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
11022 as the former is more robust if P's type is changed.
11023 Prefer xzalloc to xmalloc + memset 0.
11024 Simplify malloc-or-realloc to realloc.
11025 Don't worry about xmalloc returning a null pointer.
11026 Prefer xstrdup to xmalloc + strcpy.
11027 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
11029 * keyboard.c (apply_modifiers_uncached): Prefer local array to
11030 alloca of a constant.
11032 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11034 * xdisp.c (display_line): Fix horizontal pixel coordinates when
11035 hscroll is larger than the line width. Fixes long and futile
11036 looping inside extend_face_to_end_of_line (on a TTY) producing
11037 glyphs that are not needed and thrown away.
11039 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
11041 * marker.c (set_marker_restricted_both): Simplify by using
11044 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11046 * editfns.c (region_limit): Simplify by using clip_to_bounds.
11048 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
11050 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
11051 not defined (Bug#11768).
11052 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
11053 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
11054 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
11055 followed by gtk_box_set_homogeneous (Bug#11768).
11056 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
11057 (update_theme_scrollbar_width, xg_create_scroll_bar):
11058 Use gtk_scrollbar_new (Bug#11768).
11059 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
11060 (is_box_type): New function (Bug#11768).
11061 (xg_tool_item_stale_p): Call is_box_type.
11062 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
11063 with default display (Bug#11768).
11065 2012-07-05 Eli Zaretskii <eliz@gnu.org>
11067 * xdisp.c (window_hscroll_limited): New function.
11068 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
11069 coordinates when window's hscroll is set to insanely large
11070 values. (Bug#11857)
11072 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
11074 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
11075 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.

11133 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11135 * fileio.c (time_error_value): Check the right error number.
11136 Problem reported by Troels Nielsen in
11137 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11139 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11141 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11142 This should be fixed in a better way; see Eli Zaretskii in
11143 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11144 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11146 * fileio.c (time_error_value): Rename from special_mtime.
11147 The old name's problems were noted by Eli Zaretskii in
11148 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11150 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11151 This variable's comment says Emacs needs at least one GDB-visible
11152 symbol of type enum pvec_type, to work around GDB problems.
11153 The symbol's value doesn't matter.
11155 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11156 that causes compilation to fail on pre-C99 compilers.
11158 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11160 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
11161 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
11163 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11165 * buffer.c (init_buffer_once): Fix initialization of
11166 headers for buffer_defaults and buffer_local_symbols.
11167 Reported by Juanma Barranquero <lekktu@gmail.com>.
11169 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
11171 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
11172 * lisp.h (enum pvec_type): Use fewer bits.
11173 (PSEUDOVECTOR_SIZE_BITS): New constant.
11174 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11175 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11176 change in pvec_type.
11177 (PSEUDOVECTOR_TYPEP): New macro.
11178 (TYPED_PSEUDOVECTORP): Use it.
11179 * fns.c (internal_equal): Adapt code to extract pvectype.
11180 * emacs.c (gdb_pvec_type): Update type.
11181 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11182 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11183 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11184 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11185 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11186 abusing vector->header.next.nbytes.
11187 (live_vector_p): Use PVEC_TYPE.
11188 (mark_object): Adapt code to extract pvectype. Use switch.
11190 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11192 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11193 Tighten new eassert a bit.
11195 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11197 Fix compilation with --enable-gcc-warnings and -O1
11198 optimization level.
11199 * doprnt.c (doprnt): Change type of tem to int, initialize
11200 to avoid compiler warning. Add eassert.
11201 * search.c (simple_search): Initialize match_byte to avoid
11202 compiler warning. Add eassert.
11204 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11206 Avoid weird behavior with large horizontal scrolls.
11207 Without this change, for example, large hscroll values would
11208 mess up Emacs's display on Fedora 15 x86, presumably due to
11209 overflows in int calculations in the display code.
11210 Also, if buffers had long lines, Emacs would freeze.
11211 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11212 (set_window_hscroll): New function, containing the old guts of
11213 Fset_window_hscroll. Return the clipped value.
11214 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11215 This avoids the need to check against PTRDIFF_MAX.
11217 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11219 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11221 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11223 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11225 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11226 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11227 since GCC 4.4.6 issues a bogus warning for them.
11229 Fix bugs in file timestamp newness comparisons.
11230 * fileio.c (Ffile_newer_than_file_p):
11231 * lread.c (Fload): Use full timestamp resolution of files,
11232 not just the 1-second resolution, so that files that are only
11233 slightly newer still count as newer.
11234 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11235 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11237 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11239 * fileio.c: Improve handling of file time marker. (Bug#11852)
11240 (special_mtime): New function.
11241 (Finsert_file_contents, Fverify_visited_file_modtime):
11242 Use it to set special mtime values consistently.
11244 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11246 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11247 marker for non-existing file. (Bug#11852)
11249 2012-07-03 Glenn Morris <rgm@gnu.org>
11251 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11252 and did not make it into globals.h).
11254 2012-07-03 Tom Tromey <tromey@redhat.com>
11256 * window.c (Fset_window_margins, Fset_window_fringes)

11292 2012-07-03 Glenn Morris <rgm@gnu.org>
11294 * lisp.h (Frandom): Make it visible to C.
11295 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
11296 buffer for invisible buffers. (Bug#1229)
11298 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11300 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11301 values which aren't power of 2.
11302 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11303 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11306 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11308 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11310 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11312 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11314 * alloc.c (allocate_vector_block): Remove redundant
11315 calls to mallopt if DOUG_LEA_MALLOC is defined.
11316 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11317 avoid calls to mallopt if zero_vector is returned.
11319 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11321 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11322 is enabled, avoid dereferencing NULL current_sblock if
11325 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11327 Cleanup basic buffer management.
11328 * buffer.h (struct buffer): Change layout to use generic vector
11329 marking code. Fix some comments. Change type of 'clip_changed'
11330 to bitfield. Remove unused #ifndef old.
11331 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11332 (GET_OVERLAYS_AT): Fix indentation.
11333 (for_each_per_buffer_object_at): New macro.
11334 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
11335 (Fbuffer_local_variables): Use it.
11336 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
11337 * alloc.c (allocate_buffer): Adjust to match new layout of
11338 struct buffer. Fix comment.
11339 (mark_overlay): New function.
11340 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11341 Lisp area of struct buffer.
11342 (mark_object): Use it. Adjust marking of misc objects
11343 and related comments.
11345 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11347 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11348 wrapper that is not needed because the wrapped code is a no-op (zero
11349 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11350 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11352 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11354 * alloc.c (mark_buffer): Simplify. Remove prototype.
11355 (mark_object): Add comment. Reorganize marking of vector-like
11356 objects. Use CHECK_LIVE for all vector-like objects except buffers
11357 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11358 Avoid redundant calls to mark_vectorlike for bool vectors.
11360 2012-06-30 Glenn Morris <rgm@gnu.org>
11362 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11364 * epaths.in (PATH_SITELOADSEARCH): New.
11365 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11366 This is rather than relying on --enable-locallisppath elements
11367 having "site-lisp" in their names. (Bug#10208#25, 11658)
11369 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11371 * w32proc.c (sys_select): Accept and ignore one more argument.
11373 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11375 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11376 (pselect) [!MS_DOS]: Redirect to sys_select.
11378 * sysdep.c: Don't include dos.h and dosfns.h.
11380 * process.c (sys_select):
11381 * msdos.c (sys_select): Accept one more argument and ignore it.
11383 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11384 adapt data types and code to that.
11387 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11388 which clashes with the gnulib function of the same name.
11390 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11392 * font.c (font_style_to_value, font_style_symbolic)
11393 (font_prop_validate_style): Add type checks for values in
11396 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11398 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11401 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11403 * xdisp.c (try_window_id): Undo last change.
11405 * w32.c (getwd): Adjust commentary about startup_dir.
11406 (init_environment): Always call sys_access, even in non-MSVC
11407 builds. Don't chdir to the directory of the Emacs executable.
11408 This undoes code from 1997 which was justified by the need to
11409 "avoid conflicts when removing and renaming directories". But its
11410 downside was that every relative file name was being interpreted
11411 relative to the directory of the Emacs executable, which can never
11412 be TRT. In particular, it broke sys_access when called with
11413 relative file names.
11414 (sys_access): Map GetLastError to errno.
11416 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11422 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11425 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11427 * gnutls.c (emacs_gnutls_handshake):
11428 Add QUIT to make the loop interruptible.
11430 2012-06-29 Glenn Morris <rgm@gnu.org>
11432 * charset.c (init_charset): Make lack of etc/charsets fatal.

11440 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11441 undefined. Convert from xassert to eassert.

11443 * nsterm.m: Likewise.
11445 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

11449 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11451 Avoid integer overflow on scroll-left and scroll-right.
11452 * window.c (HSCROLL_MAX): New macro.
11453 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11454 overflow when requested scroll falls outside ptrdiff_t range.
11456 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11458 * window.h (struct window): Change type of 'hscroll',
11459 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11460 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11461 Adjust users accordingly.
11462 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11463 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11464 from EMACS_INT to ptrdiff_t.
11465 (make_window): Omit redundant initialization.

11484 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11485 adjust comments accordingly.

11567 when building with Clang.

11606 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11608 Use sprintf return value instead of invoking strlen on result.
11609 In the old days this wasn't portable, since some sprintf
11610 implementations returned char *. But they died out years ago and
11611 Emacs already assumes sprintf returns int.
11612 Similarly for float_to_string.
11613 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11619 * xdisp.c (message_dolog):
11620 * xfns.c (syms_of_xfns):
11621 Use sprintf or float_to_string result to avoid need to call strlen.
11622 * data.c (Fnumber_to_string):
11623 Use make_unibyte_string, since the string must be ASCII.
11624 * lisp.h, print.c (float_to_string): Now returns int length.
11625 * term.c (produce_glyphless_glyph):
11626 Use sprintf result rather than recomputing it.
11628 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11629 * Makefile.in (ALL_CFLAGS):
11630 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

11657 * xfns.c (x_window): Remove redundant cast.
11659 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11661 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11662 `const char *' to `char *' to avoid compiler warning.
11664 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11666 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11667 instead of truncating it to 63 (admittedly a generous limit).
11669 * process.c: Fix spelling and caps in comments.
11671 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11673 * emacs.c (setpgrp): Remove definition, unused.

11720 Remove unnecessary forward decls.
11722 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

11726 * dispnew.c (Fsleep_for, sit_for):
11727 * keyboard.c (kbd_buffer_get_event):
11728 * process.c (Faccept_process_output):
11729 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11730 This improves on the previous patch, which introduced a bug
11731 when time_t is unsigned and as wide as intmax_t.
11732 See <http://bugs.gnu.org/9000#51>.

11763 language ID in the event parameters.
11765 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11766 event.code, not the obscure "character set ID".
11768 2012-06-23 Chong Yidong <cyd@gnu.org>
11770 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

11797 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11799 Support higher-resolution time stamps (Bug#9000).
11800 The time stamps are only nanosecond-resolution at the C level,
11801 since that's the best that any real-world system supports now.
11802 But they are picosecond-resolution at the Lisp level, as that's
11803 easy, and leaves room for future OS improvements.
11805 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11808 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11809 Don't get current time unless it's needed.
11811 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11812 now provides it if it's absent.
11813 (start_atimer): Port to higher-res time stamps.
11814 Check for time stamp overflow. Don't get current time more
11815 often than is needed.
11817 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11818 Include systime.h, not time.h.
11819 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
11821 * dired.c: Include stat-time.h.
11822 (Ffile-attributes): File times now have higher resolution.
11824 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11825 (struct image): Timestamp now has higher resolution.
11827 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11828 has at least microseconds now. All uses removed.
11829 (update_frame, update_single_window, update_window, update_frame_1)
11830 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11831 (duration_to_sec_usec): Remove; no longer needed.
11833 * editfns.c (time_overflow): Now extern.
11834 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)

11839 (decode_time_components, lisp_seconds_argument): New functions.
11840 (make_time): Now static.
11841 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11842 Report an error if the time is invalid, rather than having the caller
11845 * fileio.c: Include <stat-time.h>
11846 (Fcopy_file): Copy higher-resolution time stamps.
11847 Prefer to set the time stamp via a file descriptor if that works.
11848 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11849 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11850 (Fvisited_file_modtime, Fset_visited_file_modtime):
11851 Support higher-resolution time stamps.
11853 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11855 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11857 * image.c (prepare_image_for_display, clear_image_cache)
11858 (lookup_image): Port to higer-resolution time stamps.
11860 * keyboard.c (start_polling, bind_polling_period):
11861 Check for time stamp overflow.
11862 (read_char, kbd_buffer_get_event, timer_start_idle)
11863 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11864 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11865 Port to higher-resolution time stamps. Do not assume time_t is signed.
11866 (decode_timer): New function. Timers are now vectors of length 9,
11867 not 8, to accommodate the picosecond component.
11868 (timer_check_2): Use it.
11870 * nsterm.m (select_timeout, timeval_subtract): Remove.
11871 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11872 as they're a bit more accurate and handle overflow better.
11873 (ns_select): Change prototype to be compatible with pselect.
11874 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11875 * nsterm.h (ns_select): Adjust prototype.
11877 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11878 us-resolution time stamps.
11879 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11881 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11883 * lisp.h (time_overflow): New decl.
11884 (wait_reading_process_output): First arg is now intmax_t, not int,
11885 to accommodate larger waits.
11887 * process.h (struct Lisp_Process.read_output_delay):
11888 Now counts nanoseconds, not microseconds.
11889 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11891 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11892 (wait_reading_process_output):
11893 Port to ns-resolution time stamps.
11894 (Faccept_process_output, wait_reading_process_output):
11895 Check for time stamp overflow. Do not assume time_t is signed.
11896 (select_wrapper): Remove; we now use pselect.
11897 (Fprocess_attributes): Now generates ns-resolution time stamps.
11899 * sysdep.c: Include utimens.h. Don't include utime.h
11900 or worry about struct utimbuf; gnulib does that for us now.
11901 (gettimeofday): Remove; gnulib provides a substitute.
11902 (make_timeval): New function.
11903 (set_file_times): Now sets ns-resolution time stamps.
11904 New arg FD; all uses changed.
11905 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11906 (system_process_attributes):
11907 Now returns ns-resolution time stamp. All uses changed.
11908 Check for time stamp overflow.
11910 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11911 provides a substitute now.
11913 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11914 since it guarantees struct timespec.
11915 (EMACS_TIME): Now struct timespec, so that we can support
11916 ns-resolution time stamps.
11917 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11918 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11919 (EMACS_USECS): Remove.
11920 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11921 so multiply the arg by 1000 before storing it.
11922 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11924 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
11925 Port to ns-resolution time stamps.
11926 (EMACS_TIME_NEG_P): Remove; replaced by....

11931 (make_timeval, make_lisp_time, decode_time_components): New decls.
11932 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11933 that it mishandled time_t overflow. You can't compare by subtracting!
11934 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11935 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11937 * term.c: Include <sys/time.h>.
11938 (timeval_to_Time): New function, for proper overflow wraparound.
11939 (term_mouse_position, term_mouse_click): Use it.
11941 * undo.c (record_first_change): Support higher-resolution time stamps
11942 in the undo buffer.
11943 (Fprimitive_undo): Use them when restoring time stamps.
11945 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11946 (w32_get_internal_run_time):
11947 Port to higher-resolution Emacs time stamps.
11948 (ltime): Now accepts single 64-bit integer, as that's more convenient
11951 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11953 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11954 for compatibility with pselect. Support ns-resolution time stamps.
11956 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11958 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11959 Check for time stamp overflow, and support ns-resolution time stamps.
11961 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11962 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11963 (timeval_subtract): Remove; no longer needed.
11964 (XTflash, XTring_bell, x_wait_for_event):
11965 Port to ns-resolution time stamps. Don't assume time_t is signed.

11971 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11973 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11974 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11975 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11976 staticidx goes up to 1597 out of 1600 = 0x640.)
11978 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11980 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

11992 access to `contents' member of Lisp_Vector objects with AREF and ASET
11995 2012-06-19 Chong Yidong <cyd@gnu.org>
11997 * frame.c (delete_frame): When selecting a frame on a different
11998 text terminal, do not alter the terminal's top-frame.

12001 frame's selected window and its terminal's top-frame.
12002 (unwind_format_mode_line): Restore them.
12003 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
12005 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
12006 since tty frames can be explicitly named.
12007 (prepare_menu_bars): Likewise.
12009 * term.c (Ftty_top_frame): New function.
12011 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>

12014 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
12015 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
12016 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
12017 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

12024 2012-06-18 Martin Rudalics <rudalics@gmx.at>
12026 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
12027 gets killed during executing of this function (Bug#11665).
12028 Try to always return Qt when the buffer has been actually killed.
12029 (Vkill_buffer_query_functions): In doc-string say that functions
12030 run by this hook should not change the current buffer.
12032 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
12034 Fix recently-introduced process.c problems found by static checking.
12035 * process.c (write_queue_push, write_queue_pop, send_process):
12036 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
12037 (write_queue_pop): Fix pointer signedness problem.
12038 (send_process): Remove unused local.
12040 2012-06-17 Chong Yidong <cyd@gnu.org>

12054 * lisp.h (eassert): Assume C89 or later.
12055 This removes the need for CHECK.
12056 (CHECK): Remove. Its comments about always evaluating its
12057 argument were confusing, as 'eassert' typically does not evaluate
12060 * coding.c (produce_chars): Use ptrdiff_t, not int.
12062 * xterm.c (x_draw_underwave): Check for integer overflow.
12063 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

12185 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
12186 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):

12236 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
12237 * alloc.c (make_number) [!defined make_number]:
12238 Remove, as lisp.h always defines this now.
12239 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
12240 (roundup_size): Verify that it is a power of 2.
12241 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):

12245 USE_LSB_TAG now is always defined to be either 0 or 1.
12247 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
12248 code works fine either way, and efficiency is not a concern here,
12249 as the union type is for debugging, not for production.
12250 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12251 Use an inline function on all platforms when using the union type,
12252 since this is simpler and 'static inline' can be used portably
12254 (LISP_INITIALLY_ZERO): New macro.
12255 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
12256 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

12322 2012-06-09 Michael Albinus <michael.albinus@gmx.de>
12324 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
12325 dbus_type_is_basic if available.
12326 (xd_extract_signed, xd_extract_unsigned): Rename from
12327 extract_signed and extract_unsigned, respectively. Adapt callers.

12340 would generate the diagnostic "Making \302\247 buffer-local while
12343 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12345 * dispnew.c (showing_window_margins_p): Undo last change, which

12358 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
12359 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
12361 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12363 * alloc.c (allocate_vectorlike): Fix last change.
12365 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
12367 Block-based vector allocation of small vectors.

12369 adjust comment accordingly.
12370 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
12371 to denote vector blocks. Adjust users (live_vector_p,

12394 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
12396 * doprnt.c (doprnt): Truncate multibyte char correctly.
12397 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12398 would mishandle a string argument "Xc" if X was a multibyte
12399 character of length 2: it would truncate after X's first byte
12400 rather than including all of X.
12402 2012-06-06 Chong Yidong <cyd@gnu.org>
12404 * buffer.c (word_wrap): Doc fix.
12406 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

12435 Fbuffer_local_value; can return Qunbound.
12436 (Fbuffer_local_value): Use it.
12437 (Vmode_line_format): Docstring tweaks.

12451 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12453 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12454 Convert pctcpu and pctmem to Lisp float properly.
12455 Let the compiler fold better, as 100.0/0x8000 is exact.
12457 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12459 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12462 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
12464 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
12466 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12468 For a 'struct window', replace some Lisp_Object fields to
12469 bitfields where appropriate, remove unused fields.
12470 * window.h (struct window): Remove unused 'last_mark_x' and
12471 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12472 change its type from Lisp_Object to bitfield.
12473 Change type of 'force_start', 'optional_new_start',
12474 'last_had_star', 'update_mode_line' and 'start_at_line_beg'

12479 Pacify gcc -Wdouble-precision when using Xaw.
12480 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12481 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12482 Use 'float' consistently, rather than 'float' in most places
12483 and 'double' in a couple of places.
12485 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12487 * xdisp.c (handle_stop): Detect whether we have overlay strings
12488 loaded by testing it->current.overlay_string_index to be
12489 non-negative, instead of checking whether n_overlay_strings is
12490 positive. (Bug#11587)
12492 2012-05-31 Chong Yidong <cyd@gnu.org>
12494 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12500 * search.c (search_buffer): Remove calls to
12501 r_alloc_inhibit_buffer_relocation, as it is now called by
12502 maybe_unify_char, which was the cause of relocation of buffer text
12505 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12507 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12508 for the duration of call to load_charset, to avoid problems with
12509 callers of maybe_unify_char that access buffer text through C
12512 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12513 decrement the inhibition flag, instead of just setting or
12516 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12518 Remove obsolete '#define static' cruft.
12519 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12520 This #undef was "temporary" in 2000; it is no longer needed
12521 now that '#define static' has gone away.
12522 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12523 (gray_bitmap_bits): Remove; no longer needed.
12524 All uses replaced with definiens.

12536 (safe_bcopy): Remove decl; no longer has that name.
12537 (main): Coalesce #if into single bit of code, for simplicity.
12538 Cast pointers to uintptr_t, since standard libraries want integers

12567 Do not create empty overlays with the evaporate property (Bug#9642).
12568 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12569 Bug#9642, but explicitly check that the buffer the overlay would
12570 be moved to is live and rearrange lines to make sure that errors
12571 will not put the overlay in an inconsistent state.
12572 (Fdelete_overlay): Cosmetics.
12574 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12576 * w32term.c (my_bring_window_to_top): New function.
12577 (x_raise_frame): Use handle returned by DeferWindowPos, which

12590 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12591 This avoids undefined behavior that might cause the eassert
12592 to not catch an out-of-range value.
12594 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12596 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

12611 Only r_alloc_inhibit_buffer_relocation needed to be added;
12612 the others were already declared.
12614 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12615 before checking whether it's out of range. Put the check inside
12617 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

12630 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12631 they are now on lisp.h.
12633 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12635 * search.c (search_buffer): Use it to inhibit relocation of buffer
12636 text while re_search_2 is doing its job, because re_search_2 is
12637 passed C pointers to buffer text. (Bug#11519)
12639 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12640 Update value to 24.
12642 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12643 state after an additional call to move_it_in_display_line_to, keep
12644 the values of it->max_ascent and it->max_descent found for the
12646 (pos_visible_p): Revert the comparison against bottom_y to what it
12647 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.

12652 Fix coding-related core dumps with gcc -ftrapv.
12653 The code was computing A - B, where A and B are pointers, and B is
12654 random garbage. This can lead to core dumps on platforms that
12655 have special pointer registers, and it also leads to core dumps on
12656 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12657 A - B only when B is initialized properly.
12658 * coding.c (coding_set_source, coding_set_destination): Return void.
12659 (coding_change_source, coding_change_destinations): New functions,
12660 with the old behaviors of coding_set_source and coding_set_destination.
12661 All callers that need an offset changed to use these new functions.
12663 2012-05-26 Glenn Morris <rgm@gnu.org>

12678 * w32inevt.c: Include termchar.h and window.h.
12679 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12680 moves, call note_mouse_highlight. If help_echo changed, call
12681 gen_help_event to produce help-echo message in the echo area.
12682 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12685 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12687 * lread.c (read1): Simplify slightly to avoid an overflow warning
12688 with GCC 4.7.0 on x86-64.
12690 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12692 * bidi.c (bidi_mirror_char): Revert last change: an int is
12693 definitely wide enough here.
12695 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>

12709 Use int, not EMACS_INT, where int is wide enough.
12710 (inhibit_garbage_collection, Fgarbage_collect):
12711 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12712 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
12713 int might not be wide enough.

12729 (Foverlay_recenter, last_overlay_modification_hooks_used)
12730 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
12731 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12732 (validate_region): Omit unnecessary test for b <= e,
12733 since that's guaranteed by the previous test.
12734 (adjust_overlays_for_delete): Avoid pos + length overflow.
12735 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12736 (report_overlay_modification):
12737 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12738 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12739 Omit pointer cast, which isn't needed anyway, and doesn't work
12740 after the EMACS_INT -> ptrdiff_t change.
12741 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12742 * buffer.h: Adjust decls to match defn changes elsewhere.

12746 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12747 not int, to avoid needless 32-bit limit on 64-bit hosts.
12748 (exec_byte_code): Use tighter memory-full test, one that checks
12749 for alloca overflow. Don't compute the address of the object just
12750 before an array, as that's not portable. Use EMACS_INT, not
12751 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12752 * callint.c (Fcall_interactively):
12753 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12754 * callproc.c (call_process_kill, Fcall_process):
12755 Don't assume pid_t fits into an Emacs fixnum.

12765 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12766 (casify_object): Avoid integer overflow when overallocating buffer.
12767 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12768 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12769 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12770 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12771 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
12772 integers are now checked earlier. All uses replaced with XINT.
12774 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12775 For CCL_MapSingle, check that content and value are in int range.

12777 Check that Vcode_version_map_vector is a vector.
12778 (resolve_symbol_ccl_program): Check that vector header is in range.
12779 Always copy the vector, so that we can check its contents reliably
12780 now rather than having to recheck each instruction as it's being
12781 executed. Check that vector words fit in 'int'.
12782 (ccl_get_compiled_code, Fregister_ccl_program)
12783 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12784 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
12785 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
12786 contents are in range.
12787 (Fccl_execute_on_string): Check that status is in range.
12788 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12789 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12790 Accept and return EMACS_INT, not int, because callers can pass values
12791 out of 'int' range.

12797 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12798 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12799 avoid mishandling large integers.
12800 * character.h: Adjust decls to match defn changes elsewhere.
12801 * charset.c (load_charset_map_from_file, find_charsets_in_text)

12808 Remove now-unnecessary CHECK_NATNUMs.
12809 (Fdefine_charset_internal): Check ranges here, more carefully.
12810 Don't rely on undefined behavior with signed left shift overflow.
12811 Don't assume unsigned int fits into fixnum, or that fixnum fits
12812 into unsigned int. Don't require max_code to be a valid fixnum;
12813 that's not true for gb10830 4-byte on a 32-bit host. Allow
12814 invalid_code to be a cons, for the same reason. Require code_offset
12815 to be a character. Avoid int overflow if max_char is close
12817 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12818 this is intended anyway and avoids some undefined behavior.
12819 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12820 INDEX_TO_CODE_POINT, as that's what it expects.
12821 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12822 * charset.h (DECODE_CHAR): Return int, not unsigned;
12823 this is what was intended anyway, and it avoids undefined behavior.
12824 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12825 integer-overflow issues.
12826 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12827 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12828 where the argument is EMACS_INT, and this behavior is not intended.
12829 * chartab.c (Fmake_char_table, Fset_char_table_range)
12830 (uniprop_get_decoder, uniprop_get_encoder):
12831 Don't assume fixnum fits in int.
12832 * cmds.c (move_point): New function, that does the gist of
12833 Fforward_char and Fbackward_char, but does so while checking
12834 for integer overflow more accurately.
12835 (Fforward_char, Fbackward_char): Use it.
12836 (Fforward_line, Fend_of_line, internal_self_insert)
12837 (internal_self_insert):
12838 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12897 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
12898 Do not attempt to compute the address of the object just before a

13619 2012-05-14 Glenn Morris <rgm@gnu.org>

13626 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

13629 (report_error, report_error_1, make_hdr, copy_sym)
13630 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13631 Make arguments const char *, not char *, to avoid violations of C
13632 standard and to fix some AIX warnings reported by Gilles Pion.
13634 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13636 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13637 already have overlays loaded.
13638 (handle_single_display_spec): Before returning without displaying
13639 fringe bitmap, synchronize the bidi iterator with the main display
13640 iterator, by calling iterate_out_of_display_property.
13641 (iterate_out_of_display_property): Detect buffer iteration by
13642 testing that it->string is a Lisp string.
13643 (get_next_display_element): When the current object is exhausted,
13644 and there's something on it->stack, call set_iterator_to_next to
13645 proceed with what's on the stack, instead of returning zero.
13646 (set_iterator_to_next): If called at the end of a Lisp string,
13647 proceed to consider_string_end without incrementing string
13648 position. Don't increment display vector index past the end of
13649 the display vector. (Bug#11417)
13650 (pos_visible_p): Don't report a position visible when move_it_to
13651 stopped at the last line of window, which happens to be scanned
13652 backwards by the bidi iteration. (Bug#11464)
13654 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13656 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13657 and right-margin display specs even if the spec is invalid or we
13658 are on a TTY, and thus unable to display on the fringes.
13659 That's because the text with the property will not be displayed anyway,
13660 so we need to signal to the caller that this is a "replacing"
13661 display spec. This fixes display when the spec is invalid or we
13664 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13666 * unexaix.c (make_hdr): Fix typo in prototype.
13667 This bug broke the build on AIX. Problem reported by Gilles Pion.

13671 * keyboard.c (kbd_buffer_get_event): Read special events also in

13682 2012-05-12 Glenn Morris <rgm@gnu.org>
13684 * Makefile.in (MKDIR_P): New, set by configure.
13685 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.

13696 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13697 Update dependencies.
13699 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13701 * xgselect.c (xg_select): Put maxfds+1 into a var.
13702 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13704 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13706 2012-05-10 Dave Abrahams <dave@boostpro.com>
13708 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13709 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13711 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13713 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13714 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13715 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13716 Initialize xd_registered_buses.
13718 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13720 Untag more efficiently if USE_LSB_TAG.
13721 This is based on a proposal by YAMAMOTO Mitsuharu in
13722 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13723 For an admittedly artificial (nth 8000 longlist) benchmark on
13724 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13725 Emacs's overall text size by 1%.
13726 * lisp.h (XUNTAG): New macro.
13727 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13728 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13729 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13730 * eval.c (Fautoload):
13731 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13732 * frame.h (XFRAME): Use XUNTAG.
13734 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13735 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13736 Remove unportable assumptions about print widths of types like
13738 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13739 intptr_t when converting between pointer and integer, to avoid GCC
13740 warnings about wrong width.
13742 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13744 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13745 stack for each reader_thread, instead of defaulting to 8MB
13746 determined by the linker. This avoids failures in creating
13747 subprocesses on Windows 7, see the discussion in this thread:
13748 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13750 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13752 Fix up display of the *Minibuf-0* buffer in the mini window.
13753 * keyboard.c (read_char): Don't clear the echo area if there's no
13755 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13756 contents of *Minibuf-0*) if there's no message displayed in its stead.
13758 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13760 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13763 2012-05-06 Chong Yidong <cyd@gnu.org>
13765 * lisp.mk (lisp): Update.
13767 2012-05-05 Jim Meyering <meyering@redhat.com>
13769 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13771 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13773 * data.c (PUT_ERROR): New macro.
13774 (syms_of_data): Use it. Add new error type `user-error'.
13775 * undo.c (user_error): New function.
13776 (Fprimitive_undo): Use it.
13777 * print.c (print_error_message): Adjust print style for `user-error'.
13778 * keyboard.c (user_error): New function.
13779 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13781 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13783 Do not limit current-time-string to years 1000..9999.
13784 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13785 (Fcurrent_time_string): Support any year that is supported by the
13786 underlying localtime representation. Don't use asctime, as it
13787 has undefined behavior for years outside the range -999..9999.
13789 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13791 Fix race conditions involving setenv, gmtime, localtime, asctime.
13792 Without this fix, interrupts could mess up code that uses these
13793 nonreentrant functions, since setting TZ invalidates existing
13794 tm_zone or tzname values, and since most of these functions return
13795 pointers to static storage.
13796 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13797 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13798 Grow the critical sections to include not just invoking
13799 localtime/gmtime, but also accessing these functions' results
13800 including their tm_zone values if any, and any related TZ setting.
13801 (format_time_string): Last arg is now struct tm *, not struct tm **,
13802 so that the struct tm is saved in the critical section.
13803 All callers changed. Simplify allocation of initial buffer, partly
13804 motivated by the fact that memory allocation needs to be outside
13805 the critical section.
13807 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13809 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13810 with RESET_INTERVAL.
13812 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13813 Remove duplicated buffer name initialization.
13815 2012-05-02 Jim Meyering <jim@meyering.net>
13817 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13819 * xfns.c (x_window): Use xstrdup (Bug#11375).
13821 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13823 * xdisp.c (pos_visible_p): If already at a newline from the
13824 display string before the 'while' loop, don't walk back the glyphs
13825 from it3.glyph_row. Solves assertion violation when the display
13826 string begins with a newline (egg.el). (Bug#11367)
13828 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13830 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13833 2012-05-01 Glenn Morris <rgm@gnu.org>
13835 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13836 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13837 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13838 All were removed before 23.1.
13840 * dispnew.c: Remove HAVE_LIBNCURSES test;
13841 it is always true on relevant platforms.
13843 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13844 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13846 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13848 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13850 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13851 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13854 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13856 Do not avoid creating empty evaporating overlays (Bug#9642).
13857 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13858 That is, do not delete an evaporating overlay if it becomes
13859 empty after its bounds are adjusted to fit within its buffer.
13860 This fix caused other problems, and I'm reverting it until we get
13861 to the bottom of them.
13863 2012-04-27 Chong Yidong <cyd@gnu.org>
13865 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13867 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13869 * xdisp.c (pos_visible_p): If the window start position is beyond
13870 ZV, start the display from buffer beginning. Prevents assertion
13871 violation in init_iterator when the minibuffer window is scrolled
13872 via the scroll bar.
13874 * window.c (window_scroll_pixel_based): Likewise.
13876 2012-04-27 Chong Yidong <cyd@gnu.org>
13878 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13880 2012-04-27 Glenn Morris <rgm@gnu.org>
13882 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13883 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13885 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13887 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13888 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13890 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13892 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13893 display element, check also the underlying string or buffer
13894 character. (Bug#11341)
13896 * w32menu.c: Include w32heap.h.
13897 (add_menu_item): If the call to AppendMenuW (via
13898 unicode_append_menu) fails, disable Unicode menus only if we are
13899 running on Windows 9X/Me.
13901 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13903 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13904 (xgetint): Add missing shift for LSB tags.
13906 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13908 * keyboard.c (read_char): Don't wipe echo area for select window
13909 events: These might get delayed via `mouse-autoselect-window'
13912 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13914 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13915 manipulation of :loaded-from data.
13917 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13919 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13920 now a cons (bug#11311).
13922 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13924 Do not create empty overlays with the evaporate property (Bug#9642).
13925 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13926 if it becomes empty after its bounds are adjusted to fit within
13927 its buffer. Without this fix, in a nonempty buffer (let ((o
13928 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13929 yields an empty overlay that has the evaporate property, which is
13930 not supposed to happen.
13932 Fix minor GTK3 problems found by static checking.
13933 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
13934 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13935 (struct _EmacsFixedClass, emacs_fixed_get_type):
13936 Move decls here from emacsgtkfixed.h, since they needn't be public.
13937 (emacs_fixed_get_type): Now static.
13938 (emacs_fixed_class_init): Omit unused local.
13939 (emacs_fixed_child_type): Remove; unused.

13941 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13942 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13943 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
13944 (EMACS_FIXED_GET_CLASS): Remove; unused.
13945 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
13947 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
13948 Problem reported by Juanma Barranquero for Windows -Wunused-function.
13950 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13952 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13953 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13954 (__malloc_size_t, __malloc_ptrdiff_t):
13955 Remove. All uses removed, replaced by the definiens if needed,
13956 since we can assume C89 or better now.
13957 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
13958 (protect_malloc_state, align, get_contiguous_space)
13959 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)

13964 (special_realloc, _realloc_internal_nolock, _realloc_internal)
13965 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13966 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13967 Define using prototypes, not old style.
13968 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
13969 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
13970 (align): Don't assume that signed integer overflow wraps around.
13971 Omit unused local var.
13972 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)

13974 Omit no-longer-needed casts.
13975 (valloc): Use getpagesize, not __getpagesize.
13976 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
13977 (struct hdr): The 'magic' member is now size_t, not unsigned long.
13979 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
13981 2012-04-22 Michael Albinus <michael.albinus@gmx.de>

14015 (Fdbus_send_signal, Fdbus_register_service)
14016 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.

14032 * alloc.c: Handle unusual debugging option combinations.
14033 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
14034 since the two debugging options are incompatible.
14035 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
14037 (mem_init, mem_insert, mem_insert_fixup):
14038 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

14048 (list_system_processes, system_process_attributes) [__FreeBSD__]:
14049 Use Emacs indenting style more consistently. Avoid some casts.
14050 Use 'double' consistently rather than mixing 'float' and 'double'.
14052 2012-04-21 Eduard Wiebe <usenet@pusto.de>
14054 * sysdep.c (list_system_processes, system_process_attributes):

14089 row, return zero immediately.
14090 (try_cursor_movement): If inside continuation line, don't back up
14091 farther than the first row after the header line, if any.
14092 Don't consider the header-line row as "partially visible", even if
14093 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
14095 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

14131 New extern decls, to avoid calling undeclared functions.
14132 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14133 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
14134 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
14135 (NEED_MEM_INSERT): New macro.
14136 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14137 Remove one incorrect comment and fix another.

14151 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
14152 Remove decls. This fixes an "It stinks!".
14154 * alloc.c (which_symbols): Fix alignment issue / type clash.
14156 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
14158 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
14159 (struct Lisp_Misc_Any): Likewise.
14160 (struct Lisp_Free): Likewise.
14161 * alloc.c (union aligned_Lisp_Symbol): Define.

14171 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
14172 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
14173 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14174 * s/netbsd.h, s/sol2-6.h:
14175 Remove definition of GC_MARK_STACK, since the default now works.
14176 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14177 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14178 no longer the default.
14179 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14181 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14183 * lread.c (lisp_file_lexically_bound_p):
14184 Fix hang at ";-*-\n" (bug#11238).
14186 2012-04-14 Eli Zaretskii <eliz@gnu.org>
14188 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

14200 2012-04-13 Reuben Thomas <rrt@sc3d.org>
14202 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14204 2012-04-11 Daniel Colascione <dancol@dancol.org>
14206 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14207 against is gone. It's better to use vfork now so that when Cygwin
14208 gains a new, working vfork, we use it automatically (bug#10398).
14210 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

14228 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
14230 * w32.c (w32_delayed_load): Record the full path of the library
14231 being loaded (bug#10424).
14233 2012-04-09 Glenn Morris <rgm@gnu.org>
14235 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14236 not just in the obarray, before snarfing them. (Bug#11036)
14238 * Makefile.in ($(leimdir)/leim-list.el):
14239 Pass EMACS rather than BUILT_EMACS.
14241 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
14243 * process.c (make_process):
14244 * process.h: Add integer `gnutls_handshakes_tried' member to

14253 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14254 attempts per process (connection).
14256 2012-04-09 Chong Yidong <cyd@gnu.org>
14258 * eval.c (Fuser_variable_p, user_variable_p_eh)
14259 (lisp_indirect_variable): Functions deleted.
14260 (Fdefvar): Caller changed.
14262 * callint.c (Finteractive, Fcall_interactively):
14263 * minibuf.c (Fread_variable): Callers changed.
14265 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14267 * xdisp.c (set_cursor_from_row): If the display string appears in
14268 the buffer at position that is closer to point than the position
14269 after the display string, display the cursor on the first glyph of
14270 the display string. Fixes cursor display when a 'display' text
14271 property immediately follows invisible text. (Bug#11094)
14273 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14275 composite.c: use 'double' consistently
14276 * composite.c (get_composition_id): Use 'double' consistently
14277 instead of converting 'float' to 'double' and vice versa; this is
14278 easier to understand and avoids a GCC warning.
14280 2012-04-09 Glenn Morris <rgm@gnu.org>
14282 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14283 preparation for dumping it with emacs. (Bug#4789)
14284 (leimdir): New variable.
14285 ($(leimdir)/leim-list.el): New rule.
14286 (emacs$(EXEEXT)): Depend on leim-list.el.

14304 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14305 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14306 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14307 objects, as mark_maybe_pointer will catch them otherwise.
14308 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
14309 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

14318 Support building on MS-Windows with libxml2.
14320 * makefile.w32-in (OBJ2): Add xml.$(O).
14321 (GLOBAL_SOURCES): Add xml.c.
14322 ($(BLD)/xml.$(O)): New dependency list.
14324 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14325 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14326 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14327 [!WINDOWSNT]: New macros.
14328 (init_libxml2_functions, libxml2_loaded_p): New functions.
14329 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14330 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14331 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14332 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14334 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14335 Call init_libxml2_functions before calling libxml2 functions.
14336 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14338 * emacs.c: Don't include libxml/parser.h.
14339 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14340 xmlCleanupParser directly.
14342 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14344 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14346 * indent.c (Fvertical_motion): If there is a display string at
14347 point, use it.vpos to compute how many lines to backtrack after
14348 move_it_to point. (Bug#11133)
14350 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14352 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14353 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14354 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14355 macros related to unification of CJK characters. For the details,
14356 see the discussion following the message here:
14357 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14359 2012-04-04 Chong Yidong <cyd@gnu.org>
14361 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14363 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14365 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

14373 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14375 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14376 position we get to after a call to move_it_to fails the
14377 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14378 only if we wind up in a string from display property. (Bug#11063)
14380 * window.c (Fdelete_other_windows_internal): Invalidate the row
14381 and column information about mouse highlight, so that redisplay
14382 restores it after reallocating the glyph matrices. (Bug#7464)
14384 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14385 string comes from a `display' text property, use the buffer
14386 position of that property as if we actually saw that position in
14388 (move_it_by_lines): Remove the assertion that
14389 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14390 violated when there's a before-string at the beginning of a line.
14393 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14395 * xdisp.c (append_space_for_newline): If the default face was

14397 (extend_face_to_end_of_line): Use the remapped default face for
14398 extending the face to the end of the line.
14399 (display_line): Call extend_face_to_end_of_line when the default
14400 face was remapped. (Bug#11068)
14402 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14404 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14406 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14408 * keyboard.c (safe_run_hooks_error): Don't unquote strings.

14422 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14423 (command_loop_1): Use it; inhibit selection update for

14428 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14430 2012-03-25 Kenichi Handa <handa@m17n.org>
14432 * dispextern.h (struct glyph): Change the bit length of
14433 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14435 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14437 * s/ms-w32.h (tzname): Include time.h before redirecting to

14442 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14445 * xterm.c (XTread_socket): Only modify handling_signal if
14446 !SYNC_INPUT. (Bug#11080)
14448 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14450 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14451 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14452 when fetching a multibyte character consumes more bytes than
14453 CHAR_BYTES returns, due to unification of CJK characters in
14454 string_char. (Bug#11073)
14456 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14458 * process.c (wait_reading_process_output): Handle pty disconnect
14459 by refraining from sending oneself a SIGCHLD (bug#10933).
14461 2012-03-22 Chong Yidong <cyd@gnu.org>
14463 * dispextern.h (struct it): New member string_from_prefix_prop_p.

14490 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14492 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14493 that is not from display property, accept the row as a "cursor
14494 row" if one of the string's character has a non-nil `cursor'
14495 property. Fixes cursor positioning when there are newlines in
14496 overlay strings, e.g. in icomplete.el. (Bug#11035)
14498 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14500 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14502 2012-03-12 Chong Yidong <cyd@gnu.org>
14504 * eval.c (inhibit_lisp_code): Rename from
14505 inhibit_window_configuration_change_hook; move from window.c.
14507 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14508 * window.c (run_window_configuration_change_hook)
14509 (syms_of_window): Callers changed.
14511 2012-03-11 Chong Yidong <cyd@gnu.org>
14513 * keymap.c (Fkey_description): Doc fix (Bug#9700).

14517 2012-03-10 Chong Yidong <cyd@gnu.org>
14519 * frame.c (other_visible_frames): Don't assume the selected frame
14520 is visible (Bug#10955).
14522 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
14524 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14526 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14528 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14529 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14532 2012-03-03 Glenn Morris <rgm@gnu.org>
14534 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14536 2012-03-02 Eli Zaretskii <eliz@gnu.org>

14539 position past the first glyph_row that ends at ZV. (Bug#10902)
14540 (redisplay_window, next_element_from_string): Fix typos in
14542 (redisplay_window): Pass to move_it_vertically the margin in
14543 pixels, not in screen lines.
14545 2012-03-02 Glenn Morris <rgm@gnu.org>
14547 * buffer.c (buffer-list-update-hook): Doc fix.
14549 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14551 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14552 push_it before setting up the iterator for the first overlay
14553 string, even if we have an empty string loaded.
14554 (next_overlay_string): If there's an empty string on the iterator
14555 stack, pop the stack. (Bug#10903)
14557 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14559 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14560 Suggested by Stefan Monnier in
14561 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14562 * alloc.c (widen_to_Lisp_Object): New static function.
14563 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14564 and widening them to Lisp_Objects. This would work even if
14565 USE_LSB_TAG is defined and wide integers are used, which might
14566 happen in a future version of Emacs.
14568 2012-02-25 Chong Yidong <cyd@gnu.org>
14570 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14573 * xselect.c (Fx_selection_exists_p): Doc fix.

14610 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14611 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14612 It's useless in that case, and it can cause problems on hosts
14613 that allocate halves of EMACS_INT values separately.
14614 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14615 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14616 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14617 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14618 it avoids undefined behavior on hosts where shifting right by more
14619 than the word width has undefined behavior.
14621 2012-02-19 Chong Yidong <cyd@gnu.org>
14623 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14624 (Funhandled_file_name_directory, Ffile_name_as_directory)

14666 * window.c (Fdelete_window_internal): Invalidate the mouse
14667 highlight (Bug#9904).

14745 * character.c (char_width): Return EMACS_INT, not int.
14746 (char_width, c_string_width): Check for overflow when

14780 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
14781 first 2 arguments are identical. This makes inserting large
14782 output from a subprocess an order of magnitude faster on

15236 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
15237 verifies glyph row's hash code--we have just reallocated the

15402 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15403 is set, removing the need for VIRT_ADDRESS_VARIES.
15404 (PURE_P): Use a more-efficient implementation that needs just one

15421 behave as if the cursor position were at the window margin.
15423 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15424 and the cursor position is out of bounds, behave as if the cursor
15425 position were at the window margin. (Bug#10075)
15427 2011-11-18 Chong Yidong <cyd@gnu.org>
15429 * window.c (Fwindow_combination_limit): Make first argument

15451 compute_line_metrics.
15452 (compute_line_metrics): Call row_hash, instead of computing the
15455 * dispnew.c (verify_row_hash): Call row_hash for computing the
15456 hash code of a row, instead of duplicating code from xdisp.c.
15458 * dispextern.h (row_hash): Add prototype.
15460 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
15462 * frame.c (delete_frame): Don't delete the terminal when the last

15511 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
15512 with user-defined heap size. Bump the default size of the temacs

15516 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15517 current_matrix and desired_matrix. (Bug#9990)
15518 (verify_row_hash) [XASSERTS]: New function.

15563 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
15565 Avoid some portability problems by eschewing 'extern inline' functions.
15566 The trivial performance wins aren't worth the portability hassles; see
15567 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15569 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

15617 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
15618 This is also needed for porting to any host where GC_MARK_STACK is
15619 not GC_MAKE_GCPROS_NOOPS.
15620 (which_symbols): Use it.

15635 * xmenu.c (cleanup_widget_value_tree): New function.
15636 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15637 calling free_menubar_widget_value_tree directly (Bug#9830).
15639 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>

15643 (window_box_width, window_box_left, window_box_left_offset)
15644 (window_box_right, window_box_right_offset): Declare extern.
15645 Otherwise, these inline functions do not conform to C99 and
15646 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15647 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15648 * intervals.c (adjust_intervals_for_insertion)

15651 (static_offset_intervals): Remove.
15652 (offset_intervals): Rewrite using the old contents of
15653 static_offset_intervals. The old version didn't conform to C99
15654 because an extern inline function contained a reference to an
15655 identifier with static linkage.

15677 (Fwindow_vscroll): Doc fix.

15679 argument, since it makes no sense to pass a live window and for
15680 consistency with window-child.

15721 official. Move initialization of image_cache_refcount and
15722 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15890 (w32font_open_internal, compute_metrics):
15891 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15892 instead of calling the "wide" APIs directly.

15967 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15968 * editfns.c: Rewrite current-time-zone so that it invokes
15969 the equivalent of (format-time-string "%Z") to get the time zone name.
15970 This fixes a bug when the time zone name contains characters that
15971 need converting from the system time locale to Emacs internal format.
15972 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15973 that patch fixed format-time-string to do the conversion, but
15974 I forgot to fix current-time-zone.
15975 (format_time_string): New function, containing most of
15976 what Fformat_time_string used to contain.
15977 (Fformat_time_string): Rewrite in terms of format_time_string.
15978 This doesn't change this function's behavior.
15979 (current-time-zone): Rewrite to use format_time_string.
15980 This fixes the bug reported by Michael Schierl in
15981 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15982 Jason Rumney's 2007-06-07 change worked around this bug, but
15984 * systime.h (tzname, timezone): Remove no-longer-used declarations.

15988 * xdisp.c (start_display): If the character at POS is displayed
15989 via a display vector, reset IT->current.dpvec_index to zero.
15990 (try_window_reusing_current_matrix): If a line ends in a display
15991 vector or the next line starts in a display vector, continue
15992 redrawing the window even though the character position of
15993 start_row was reached.
15996 2011-10-18 Chong Yidong <cyd@gnu.org>
15998 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15999 with nobreak-char-display too.
16001 2011-10-18 Eli Zaretskii <eliz@gnu.org>
16003 Fix part 3 of bug#9771.
16004 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
16005 (bidi_resolve_neutral): Don't enter the expensive loop looking for
16006 non-neutral characters if the current character is a paragraph
16007 separator (a.k.a. Newline). This avoids running the same
16008 expensive loop twice, once when we consume the preceding newline
16009 and the other time when the line actually needs to be displayed.
16010 Avoid the loop when we see neutrals on the base embedding level
16011 following a character whose directionality is the same as the
16012 paragraph's. This avoids running the expensive loop when a line
16013 ends in a long sequence of neutrals, like control characters.
16014 Add assertion against STRONG_AL type. Slightly rearrange code
16015 that determines the type of a neutral given the first non-neutral
16017 (bidi_level_of_next_char): Set next_en_pos to zero when
16018 invalidating its info.
16020 2011-10-17 Eli Zaretskii <eliz@gnu.org>
16022 * xdisp.c (push_display_prop): Determine whether to record string
16023 or buffer position by IT->string, not by IT->method. Allow
16024 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
16025 (move_it_vertically_backward): Don't look for character position
16026 immediately after the newline when in a continuation line.
16029 2011-10-15 Martin Rudalics <rudalics@gmx.at>
16031 * window.c (coordinates_in_window): Rewrite and delabelize
16032 vertical border check. (Bug#5357) (Bug#9618)
16034 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
16036 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
16037 errors in XSetWindowBorder (bug#9310).
16039 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
16041 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
16042 avoid crash when xmalloc overrun checking is enabled.
16044 2011-10-13 Eli Zaretskii <eliz@gnu.org>
16046 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
16047 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
16048 cursor motion with <left> and <right> arrow keys.
16050 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
16051 some callers set that themselves.
16053 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16055 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
16056 display string and the previous row comes from the same string and
16057 is empty. (Bug#9739) (Bug#9738)
16059 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
16061 * doc.c (get_doc_string): Encode file name (bug#9735).
16063 2011-10-12 Eli Zaretskii <eliz@gnu.org>
16065 * bidi.c (bidi_level_of_next_char):
16066 * xdisp.c (get_visually_first_element): Remove old incorrect
16067 comments regarding the Unicode Line Separator character.
16069 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
16071 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
16073 * alloc.c (Fgc_status): Do not access beyond zombies array
16074 boundary if nzombies > MAX_ZOMBIES.
16075 * alloc.c (dump_zombies): Add missing format specifier.
16077 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16079 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16080 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16082 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16083 Some packages use them to denote characters with modifiers.
16085 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16087 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16088 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16089 matching a pp-number. Rename parameter var to var1.
16091 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16093 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16095 2011-10-08 Glenn Morris <rgm@gnu.org>
16097 * callint.c (Fcall_interactively): Give a more explicit error for the
16098 'c' case with a non-character input. (Bug#8479)
16100 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16102 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16104 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16105 lines that are hscrolled on the left.
16107 * dispnew.c (buffer_posn_from_coords): Account for a possible
16108 presence of header-line. (Bug#4426)
16110 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16112 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16113 Don't advertise functionality which we discourage or doesn't work.
16115 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16117 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16118 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16119 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16120 this makes Emacs dump core during garbage collection on rare
16121 occasions. sizeof is obviously inferior to offsetof here, so
16122 stick with offsetof.
16123 (GC_POINTER_ALIGNMENT): New macro.
16124 (mark_memory): Omit 3rd (offset) arg; caller changed.
16125 Don't assume EMACS_INT alignment is the same as pointer alignment.
16127 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16129 * keyboard.c (read_key_sequence_remapped): New var.
16130 (read_key_sequence): Compute remapping in the right buffer.
16131 (command_loop_1): Use read_key_sequence's remapping directly.
16133 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16135 * dired.c (file_name_completion): Don't expand file name.
16136 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16137 before checking file name handler.
16139 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16140 they've been requested explicitly (bug#9591).
16142 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16144 * keymap.c (Fsingle_key_description): Use make_specified_string
16145 instead of build_string to build string from push_key_description.
16148 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16150 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16151 This fixes a Y2038 bug on 64-bit hosts.
16152 * buffer.c (reset_buffer):
16153 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16154 (Fclear_buffer_auto_save_failure):
16155 Use 0, not -1, to represent an unset failure time, since time_t
16156 might not be signed.
16158 Remove dependency on glibc malloc internals.
16159 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16160 Move back here from lisp.h, but with their new implementations.
16161 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16162 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16163 * charset.c (charset_table_init): New static var.
16164 (syms_of_charset): Use it instead of xmalloc. This removes a
16165 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16166 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16167 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16168 Move back to alloc.c.
16169 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16170 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16172 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16174 * nsterm.m (windowDidResize): Call x_set_window_size only when
16175 ns_in_resize is true. Otherwise set pixelwidth/height and
16176 call change_frame_size (Bug#9628).
16178 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16180 Port --enable-checking=all to Fedora 14 x86-64.
16181 * charset.c (syms_of_charset): Also account for glibc malloc's
16182 internal overhead when calculating the initial malloc maximum.
16184 Port --enable-checking=all to Fedora 14 x86.
16185 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16187 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16188 (overrun_check_realloc, overrun_check_free):
16189 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16190 That way, xmalloc returns a properly-aligned pointer even if
16191 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16192 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16193 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16194 into account when calculating the initial malloc maximum.
16195 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16196 Move here from alloc.c, so that charset.c can use it too.
16197 Properly align; the old code wasn't right for common 32-bit hosts
16198 when configured with --enable-checking=all.
16199 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16200 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16202 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16204 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16207 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16209 * xdisp.c (compute_display_string_end): If there's no display
16210 string at CHARPOS, return -1.
16212 * bidi.c (bidi_fetch_char): When compute_display_string_end
16213 returns a negative value, treat the character as a normal
16214 character not covered by a display string. (Bug#9624)
16216 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16218 * lread.c (Fread_from_string): Fix typo in docstring.
16220 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16222 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16223 newline, reseat the iterator instead of bidi-iterating there one
16224 character at a time. (Bug#9610)
16225 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16226 TO_CHARPOS if the bidi iterator is at base embedding level.
16228 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16230 * lread.c (readevalloop): Use correct code for NBSP.
16231 (read1): Likewise. (Bug#9608)
16233 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16235 * dbusbind.c (Fdbus_register_signal): When service is not
16236 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16238 2011-09-25 Glenn Morris <rgm@gnu.org>
16240 * buffer.c (truncate-lines): Doc fix.
16242 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16244 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16245 (Fset_window_next_buffers): Doc fix.
16247 2011-09-24 Glenn Morris <rgm@gnu.org>
16249 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16251 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16253 Fix minor problems found by static checking.
16254 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16255 * indent.c (Fvertical_motion): Fix == vs = typo.
16257 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16259 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16260 Default value is now t. Doc fix.
16262 * indent.c (Fvertical_motion): Compute and apply the overshoot
16263 logic when moving up, not only when moving down. Fix the
16264 confusing name and values of the it_overshoot_expected variable;
16265 logic changes accordingly. (Bug#9254) (Bug#9549)
16267 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16268 CHARPOS is covered by a display string which includes newlines.
16269 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16270 is covered by a display string with embedded newlines.
16272 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16274 * dbusbind.c (Fdbus_register_signal): Add match rule to
16275 Vdbus_registered_objects_table. (Bug#9581)
16276 (Fdbus_register_method, Vdbus_registered_objects_table):
16279 2011-09-24 Jim Meyering <meyering@redhat.com>
16281 do not ignore write error for any output size
16282 The previous change was incomplete.
16283 While it makes emacs --batch detect the vast majority of stdout
16284 write failures, errors were still ignored whenever the output size is
16285 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16286 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16287 && echo FAIL: ignored write error
16288 FAIL: ignored write error
16289 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16290 && echo FAIL: ignored write error
16291 FAIL: ignored write error
16292 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16294 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16296 * emacs.c (Fkill_emacs): In noninteractive mode exit
16297 non-successfully if a write error occurred on stdout. (Bug#9574)
16299 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16301 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16304 * dispextern.h (struct it): Update the comment documenting what
16307 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16309 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16310 a display string, extend search for cursor position to end of row.
16311 (find_row_edges): If the row ends in a newline from a display
16312 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16313 Handle the case of a display string with multiple newlines.
16314 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16315 non-empty line. Fixes confusing cursor motion with arrow keys at
16316 the beginning of a line that starts with whitespace.
16318 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16320 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16323 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16325 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16326 boolean (Bug#9154).
16328 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16330 * xdisp.c (display_line): Record maximum and minimum buffer
16331 positions even if no glyphs were produced (e.g., by a zero-width
16332 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16333 buffer positions that will be removed from the glyph row because
16335 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16336 column is beyond frame width: don't subtract 1 "pixel" when
16337 computing width of the stretch.
16338 (reseat_at_next_visible_line_start): Undo the change made on
16339 2011-09-17 that saved paragraph information and restored it after
16340 the call to `reseat'. (Bug#9545)
16342 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16344 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16345 and turn window cursor on if cleared (Bug#9415).
16347 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16349 * search.c (boyer_moore): Take unibyte characters from pattern
16350 literally. (Bug#9458)
16352 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16354 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16356 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16358 Fix minor problem found by static checking.
16359 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16360 initialized, to pacify gcc -Wuninitialized.
16362 * fileio.c: Report proper errno when syscall falls.
16363 (Finsert_file_contents): Save and restore errno,
16364 so that report_file_error outputs the correct diagnostic.
16365 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16367 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16369 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16371 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16373 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16374 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16376 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16378 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16379 about the current paragraph and restore it after the call to reseat.
16381 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16382 (bidi_find_paragraph_start): Search back for paragraph beginning
16383 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16384 (bidi_move_to_visually_next): Only trigger paragraph-related
16385 computations when the last character is a newline or at EOB, not
16386 just any NEUTRAL_B. (Bug#9470)
16388 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16389 truncated lines if point is covered by a display string. (Bug#9524)
16391 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16393 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16394 (cons_to_x_long): New function.
16395 (lisp_data_to_selection_data): Use it. Correct the test for
16396 short-versus-long data; it was negated. Break out of vector
16397 loop, for efficiency, when a long datum is discovered.
16399 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16401 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16403 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16405 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16406 GCC PR/17406) by declaring this function with external scope.
16408 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16410 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

16415 * editfns.c (Fformat): Correctly handle text properties on "%%".
16417 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16419 * xterm.c (x_draw_composite_glyph_string_foreground):
16420 * w32term.c (x_draw_composite_glyph_string_foreground):
16421 * term.c (encode_terminal_code):
16422 * composite.c (composition_update_it, get_composition_id):
16423 * xdisp.c (get_next_display_element)
16424 (fill_composite_glyph_string): Add comments about special meaning
16425 of TAB characters in a composition.
16427 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16429 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16430 This occurs when processing a multibyte format.
16431 Problem reported by Wolfgang Jenker.
16433 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16435 * xdisp.c (try_cursor_movement): Only check for exact match if
16436 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16438 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16440 Remove unused external symbols.
16441 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16442 * xdisp.c (calc_pixel_width_or_height): Now static.
16443 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16444 * indent.c (check_display_width):
16445 * w32term.c: Fix comment to match code.
16446 * xterm.c, xterm.h (x_catching_errors): Remove.
16448 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16450 * xselect.c: Use signed conversions more consistently (Bug#9498).
16451 (selection_data_to_lisp_data): Assume incoming selection data are
16452 signed integers, not unsigned. This is to be consistent with
16453 outgoing selection data, which was modified to use signed integers
16454 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16455 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16456 expects long, not unsigned long.
16458 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16460 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16461 computation of loop end. Reported by Johan Bockgård
16464 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16466 * frame.c (Fother_visible_frames_p): Function deleted.
16468 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16470 * indent.c (compute_motion): Process display vector front to back
16471 rather than the other way around. (Bug#2496)
16473 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16475 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16477 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16479 * minibuf.c (Fread_from_minibuffer): Doc fix.
16481 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16483 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16484 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16486 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16488 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16489 value for non-existent files.
16491 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16493 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16494 set its "size" to -1. This will set the modtime_size field of
16495 the corresponding buffer to -1, which is what
16496 verify-visited-file-modtime expects for files that do not exist.
16499 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16501 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16503 * lisp.h: ... from here. push_key_description is no longer
16504 defined in keyboard.c, so its declaration should not be in
16505 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16506 logically belongs with push_key_description.
16508 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16510 * buffer.h: Include <sys/types.h> instead of <time.h>.
16511 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16512 Problem reported by Herbert J. Skuhra.
16514 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16516 * xml.c (parse_region): Make the parsing work for
16517 non-comment-starting XML files again (bug#9144).
16519 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16521 * image.c (gif_load): Fix calculation of bottom and right corner.
16524 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16526 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16527 redisplay in small windows.
16529 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16531 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16533 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16535 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16536 Operate on live windows only.
16538 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16540 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16542 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16544 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16545 only under bidi iteration.
16547 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16549 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16551 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16553 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16554 Without this fix, the command to link temacs failed due to an
16555 undefined symbol __builtin_isnan. This is because
16556 /usr/include/iso/math_c99.h #defines isnan(x) to
16557 __builtin_isnan(x), but the bundled gcc, which identifies itself
16558 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16560 * floatfns.c (isnan): #undef, and then #define to a clone of
16562 (Fisnan): Always define, since it's always available now.
16563 (syms_of_floatfns): Always define isnan at the Lisp level.
16565 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16567 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16569 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16571 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16572 The previous code assumed that file offsets (off_t values) fit in
16573 EMACS_INT variables, which is not true on typical 32-bit hosts.
16574 The code messed up by falsely reporting buffer overflow in cases
16575 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16576 when "big" contains more than 2**29 bytes, even though this
16577 inserts just one byte and does not overflow the buffer.
16578 (Finsert_file_contents): Store file offsets as off_t
16579 values, not as EMACS_INT values. Check for overflow when
16580 converting between EMACS_INT and off_t. When checking for
16581 buffer overflow or for overlap, take the offsets into account.
16582 Don't use EMACS_INT for small values where int suffices.
16583 When checking for overlap, fix a typo: ZV was used where
16584 ZV_BYTE was intended.
16585 (Fwrite_region): Don't assume off_t fits into 'long'.
16586 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16588 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16590 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16592 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16594 sprintf-related integer and memory overflow issues (Bug#9412).
16596 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16597 (esprintf, exprintf, evxprintf): New functions.
16598 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16599 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16600 (modify_event_symbol): Do not assume that the length of
16601 name_alist_or_stem is safe to alloca and fits in int.
16602 (Fexecute_extended_command): Likewise for function name and binding.
16603 (Frecursion_depth): Wrap around reliably on integer overflow.
16604 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16605 since some callers pass EMACS_INT values.
16606 (Fsingle_key_description): Don't crash if symbol name contains more
16607 than MAX_ALLOCA bytes.
16608 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16609 (get_minibuffer): Arg is now EMACS_INT, not int.
16610 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16611 (esprintf, exprintf, evxprintf): New decls.
16612 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16614 * dbusbind.c (signature_cat): New function.
16615 (xd_signature, Fdbus_register_signal):
16616 Do not overrun buffer; instead, report string overflow.
16618 * dispnew.c (add_window_display_history): Don't overrun buffer.
16619 Truncate instead; this is OK since it's just a log.
16621 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16622 even if the time zone offset is outlandishly large.
16623 Don't mishandle offset == INT_MIN.
16625 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16626 when creating daemon; the previous buffer-overflow check was incorrect.
16628 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16629 which has the guts of the old verror function.
16631 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16632 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16634 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16635 (font_unparse_xlfd): Don't blindly alloca long strings.
16636 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16637 fits in int, when using sprintf. Use single snprintf to count
16638 length of string rather than counting it via multiple sprintfs;
16639 that's simpler and more reliable.
16640 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16641 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16642 sprintf, in case result does not fit in int.
16644 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16645 (fontset_from_font): Print it.
16647 * frame.c (tty_frame_count): Now printmax_t, not int.
16648 (make_terminal_frame, set_term_frame_name): Print it.
16649 (x_report_frame_params): In X, window IDs are unsigned long,
16650 not signed long, so print them as unsigned.
16651 (validate_x_resource_name): Check for implausibly long names,
16652 and don't assume name length fits in 'int'.
16653 (x_get_resource_string): Don't blindly alloca invocation name;
16654 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16657 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16658 (xg_check_special_colors, xg_set_geometry):
16659 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16661 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16662 Use esprintf, not sprintf, in case result does not fit in int.
16664 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16665 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16666 it as a large positive number.
16667 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16668 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16670 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16671 in case result does not fit in int.
16673 * print.c (float_to_string): Detect width overflow more reliably.
16674 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16675 buffer overrun. Don't assume list length fits in 'int'. Treat
16676 print length of 0 as 0, not as infinity; to be consistent with other
16677 uses of print length in this function. Don't overflow print length
16678 index. Don't assume hash table size fits in 'long', or that
16679 vectorlike size fits in 'unsigned long'.
16681 * process.c (make_process): Use printmax_t, not int, to format
16682 process-name gensyms.
16684 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16686 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16687 to avoid potential buffer overrun.
16689 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16690 if X resource line is longer than 512 bytes.
16692 * xfns.c (x_window): Make sprintf buffer a bit bigger
16693 to avoid potential buffer overrun.
16695 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16697 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16699 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16701 Integer overflow fixes for scrolling, etc.
16702 Without these, Emacs silently mishandles large integers sometimes.
16703 For example, "C-u 4294967297 M-x recenter" was treated as if
16704 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16706 * xdisp.c (try_window_id): Check Emacs fixnum range before
16707 converting to 'int'.
16709 * window.c (window_scroll_line_based, Frecenter):
16710 Check that an Emacs fixnum is in range before assigning it to 'int'.
16711 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16712 values converted from Emacs fixnums.
16713 (Frecenter): Don't wrap around a line count if it is out of 'int'
16714 range; instead, treat it as an extreme value.
16715 (Fset_window_configuration, compare_window_configurations):
16716 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16718 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16719 that can exceed INT_MAX. Check that EMACS_INT value is in range
16720 before assigning it to the (possibly-narrower) index.
16721 (match_limit): Don't assume that a fixnum can fit in 'int'.
16723 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16726 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16727 (Fvertical_motion): Don't wrap around LINES values that don't fit
16728 in 'int'. Instead, treat them as extreme values. This is good
16729 enough for windows, which can't have more than INT_MAX lines anyway.
16731 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16733 * Require libxml/parser.h to avoid compilation warning.
16735 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16737 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16738 since this reportedly can destroy thread storage.
16740 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16742 * syntax.c (find_defun_start): Update all cache variables if
16743 exiting early (Bug#9401).
16745 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16747 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16749 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16750 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16751 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16753 * term.c (tty_append_glyph): New function.
16754 (produce_stretch_glyph): Static function and its prototype deleted.
16756 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16759 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16761 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16762 when checking :margin (Bug#9390).
16763 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16764 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16765 so that the name doesn't mislead. All uses changed.
16767 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16769 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16772 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16774 * xdisp.c (move_it_to): Don't bail out early when reaching
16775 position beyond to_charpos, if we are scanning backwards.
16776 (move_it_vertically_backward): When DY == 0, make sure we get to
16777 the first character in the line after the newline.
16779 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16781 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16782 (ccl_driver): Do not generate an out-of-range pointer.
16783 (Fccl_execute_on_string): Remove unnecessary check for
16784 integer overflow, noted by Stefan Monnier in
16785 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16786 Remove a FIXME that didn't need fixing.
16787 Simplify the newly-introduced buffer reallocation code.
16789 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16791 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16793 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16795 Integer and memory overflow issues (Bug#9196).
16797 * doc.c (get_doc_string): Rework so that
16798 get_doc_string_buffer_size is the actual buffer size, rather than
16799 being 1 less than the actual buffer size; this makes xpalloc more
16802 * image.c (x_allocate_bitmap_record, cache_image):
16803 * xselect.c (Fx_register_dnd_atom):
16804 Simplify previous changes by using xpalloc.
16806 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16807 since either will do and ptrdiff_t is convenient with xpalloc.
16809 * charset.c (charset_table_size)
16810 (struct charset_sort_data.priority): Now ptrdiff_t.
16811 (charset_compare): Don't overflow if priorities differ greatly.
16812 (Fsort_charsets): Don't assume list length fits in int.
16813 Check for size-calculation overflow when allocating sort data.
16814 (syms_of_charset): Allocate an initial charset table that is
16815 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16817 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16819 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16820 The actual value is always <= INT_MAX, and leaving it unsigned made
16821 overflow checking harder.
16823 * dispextern.h (struct glyph_matrix.rows_allocated)
16824 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16825 with xpalloc. The values are still always <= INT_MAX.
16827 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16829 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16830 (SAFE_NALLOCA): New macro.
16832 * region-cache.c (struct boundary.pos, find_cache_boundary)
16833 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16834 (set_cache_region, invalidate_region_cache)
16835 (revalidate_region_cache, know_region_cache, region_cache_forward)
16836 (region_cache_backward, pp_cache):
16837 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16838 so that ptrdiff_t * can be passed to xpalloc.
16839 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16840 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16841 (pp_cache): Don't assume cache_len fits in int.
16842 * region-cache.h: Adjust extern decls to match.
16844 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16845 EMACS_INT, since either will do, for xpalloc.
16847 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16848 (xnmalloc, xnrealloc, xpalloc): New functions.
16850 * bidi.c (bidi_shelve_header_size): New constant.
16851 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16852 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16854 * bidi.c (bidi_cache_shrink):
16855 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16857 Don't update size of array until after memory allocation succeeds,
16858 because xmalloc/xrealloc may not return.
16859 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16860 now that we have proper integer overflow checking.
16861 (record_overlay_string, overlay_strings): Catch overflows when
16862 calculating size of overlay_str_buf.
16864 * callproc.c (Fcall_process): Check for size overflow when
16865 calculating size of args2.
16866 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16867 Normally we prefer signed values, but sticking with ptrdiff_t would
16868 require adding more-complicated checks.
16870 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16871 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16872 Redo buffer-overflow calculations to avoid integer overflow.
16873 Add a FIXME comment where memory seems to be over-allocated.
16875 * character.c (Fstring): Check for size-calculation overflow.
16877 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16878 unnecessary integer overflow. Check for size overflow.
16879 (encode_coding_object): Don't update size until xmalloc succeeds.
16881 * composite.c (get_composition_id): Check for overflow in glyph
16882 length calculations.
16884 Integer and memory overflow fixes for display code.
16885 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16886 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16887 (scrolling_window): Check for overflow in size calculations.
16888 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16889 Don't assume glyph table len fits in int.
16890 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
16891 (row_table_size): Now ptrdiff_t, not int.
16892 (scrolling_window): Avoid overflow in size calculations.
16893 Don't update size until allocation succeeds.
16894 * fns.c (concat): Check for overflow in size calculations.
16895 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.

16911 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16913 * emacs.c (main): Do not reallocate argv, since there is a null at
16914 the end that can be overwritten, and this way there's no need to
16915 worry about size-calculation overflow.

17033 (Fx_change_window_property): Use ptrdiff_t, not int, to count
17034 sizes, since they can exceed INT_MAX in size. Check for size

17045 (X_LONG_MIN): New macros.
17046 Use them to make the following changes clearer.
17047 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

17049 future maintainers not to raise the value too much later.
17050 (SELECTION_QUANTUM): Remove, replacing with ...
17051 (selection_quantum): ... new function, which avoids overflow.
17053 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
17054 assumption that selection length fits in 'int'.

17071 Don't store size until memory allocation succeeds.
17072 (x_get_window_property): Plug memory leak on memory exhaustion.
17073 Don't double-block input; malloc is safe here. Don't assume 2**34
17074 - 4 fits in unsigned long. Add an xassert to check
17075 XGetWindowProperty overflow. Be more careful about overflow
17076 calculations, and distinguish size from memory overflow better.

17083 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17084 result parameters unless successful. Rely on cons_to_unsigned
17085 to report problems with elements; the old code wasn't right anyway.

17120 * lisp.h (hash_lookup, hash_put):
17121 * minibuf.c (Ftest_completion):
17122 Use ptrdiff_t for hash table indexes, not int (which is too
17123 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17124 32-bit --with-wide-int hosts).
17126 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17127 Add a FIXME comment about memory leaks.

17165 Change bufsize argument back to int, undoing my 2011-03-30 change.
17166 We prefer signed types, and int is wide enough here.
17167 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17168 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17169 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17170 length, not size_t. Use ptrdiff_t for index, not int.
17171 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17172 possibility of integer overflow.

17200 Prefer int to unsigned where either will do.
17201 (tiff_handler): New function, combining the cores of the
17202 old tiff_error_handler and tiff_warning_handler.

17204 stack buffer overflows. It uses only the features of vsnprintf
17205 that are common to both POSIX and native Microsoft.
17206 (tiff_error_handler, tiff_warning_handler): Use it.
17207 (tiff_load, gif_load, imagemagick_load_image):
17208 Don't assume :index value fits in 'int'.
17209 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

17254 positioning on the newline at EOL of R2L text within L2R
17255 paragraph, and vice versa.
17256 (try_cursor_movement): Check continued rows, in addition to
17257 continuation rows. Fixes unwarranted scroll when point enters a
17258 continued line of R2L text within an L2R paragraph, or vice versa.
17259 (cursor_row_p): Consider the case of point being equal to
17260 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

17289 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17290 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17291 candidate is selected by the mouse, and that candidate has a
17292 composed character under the mouse.
17294 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17295 coordinates reported by pos-visible-in-window-p for a composed

17305 consider it a hit if to_charpos is anywhere in the range of the
17306 composed buffer positions.
17308 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17310 * image.c (gif_load): Don't assume that each subimage has the same
17311 dimensions as the base image. Handle disposal method that is
17312 "undefined" by the gif spec (Bug#9335).
17314 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17316 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17326 a composition, take its buffer position from IT->cmp_it.charpos.
17327 Fixes cursor positioning at the beginning of a line that begins
17328 with a composed character.
17330 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17332 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17333 character bidirectional type, use STRONG_L instead. Fixes crashes
17334 in a buffer produced by `describe-categories'.
17336 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17337 members before the level stack, so they would be saved and
17338 restored when copying iterator state. Fixes incorrect reordering
17339 around TABs covered by display properties.
17341 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17343 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
17345 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
17347 * eval.c (internal_condition_case, internal_condition_case_1)
17348 (internal_condition_case_2, internal_condition_case_n):
17349 Remove unnecessary aborts (Bug#9081).
17351 2011-08-17 Eli Zaretskii <eliz@gnu.org>
17353 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
17354 has no `load' handler, try opening the file locally. (Bug#9311)
17356 2011-08-16 Ken Brown <kbrown@cornell.edu>
17358 * gmalloc.c: Expand comment.
17360 2011-08-16 Eli Zaretskii <eliz@gnu.org>
17362 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
17363 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
17365 2011-08-16 Ken Brown <kbrown@cornell.edu>
17367 Fix memory allocation problems in Cygwin build (Bug#9273).
17369 * unexcw.c ( __malloc_initialized): Declare external variable.

17374 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
17376 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
17377 in the static heap.
17378 [CYGWIN] (special_realloc): New function.
17379 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
17380 requests to realloc storage in the static heap.
17382 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
17384 * bidi.c (bidi_initialize): Remove unused local.

17391 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
17393 * dispextern.h: Fix a typo in the comment to bidi_type_t.
17395 * chartab.c: Improve commentary for the uniprop_table API.
17397 * bidi.c (bidi_paragraph_init): Support zero value of
17398 bidi_ignore_explicit_marks_for_paragraph_level.
17399 (bidi_initialize): Use uniprop_table instead of including
17400 biditype.h and bidimirror.h.
17402 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
17403 coordinates of the iterator when restoring from ppos_it.
17406 2011-08-14 Kenichi Handa <handa@m17n.org>
17408 * process.c (create_process): Call setup_process_coding_systems
17409 after the pid of the process is set to -1 (Bug#8162).
17411 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17413 * xdisp.c (move_it_in_display_line_to): Don't invoke
17414 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17415 ppos_it. Fixes vertical cursor motion when line beginning is
17416 covered by an image. (Bug#9296)
17418 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17420 * nsterm.h (ns_run_ascript): Declare.
17421 (NSAPP_DATA2_RUNASSCRIPT): Define.
17423 * nsfns.m (as_script, as_result, as_status): New static variables.
17424 (ns_run_ascript): New function.
17425 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17426 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17427 the event loop. Get status from as_status (Bug#7276).
17429 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17430 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17431 the event loop (Bug#7276).
17433 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17435 * gnutls.c (QCgnutls_bootprop_priority)
17436 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
17437 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
17438 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
17439 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
17440 (QCgnutls_bootprop_verify_hostname_error)
17441 (QCgnutls_bootprop_callbacks_verify): Rename from
17442 Qgnutls_bootprop_..., all uses changed.
17444 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
17447 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
17449 * xfaces.c (Qframe_set_background_mode): Now static.
17450 * dispextern.h (Qframe_set_background_mode): Remove decl.

17454 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
17456 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
17457 (Fnetwork_interface_list): Allocate in increments of bytes instead
17458 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17459 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17461 (struct ifflag_def): notrailers is smart on OSX.
17462 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17463 Get hardware address with getifaddrs if available.
17465 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17467 * xdisp.c (iterate_out_of_display_property): xassert that
17468 IT->position is set to within IT->object's boundaries. Break from
17469 the loop as soon as EOB is reached; avoids infloops in redisplay
17470 when IT->position is set up wrongly due to some bug.
17471 Set IT->current to match the bidi iterator unconditionally.
17472 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17473 entry. Force push_it to save on the stack the current
17474 buffer/string position, to be restored by pop_it. Fix flags in
17475 the iterator structure wrt the object coming from a display
17476 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17477 properties. (Bug#9284)
17479 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17481 * fontset.c (fontset_get_font_group): Add proper type checks.
17484 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17486 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
17487 and LC_VERSION_MIN_MACOSX.
17488 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
17489 (dump_it) [LC_FUNCTION_STARTS]: Use it.
17491 2011-08-08 Eli Zaretskii <eliz@gnu.org>
17493 * xdisp.c (forward_to_next_line_start): Allow to use the
17494 no-display-properties-and-no-overlays under bidi display.
17495 Set disp_pos in the bidi iterator to avoid searches for display
17496 properties and overlays.
17498 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17500 * editfns.c (Fset_time_zone_rule): Document relationship with the
17503 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
17504 the font entity extracted from the cache (Bug#8109).
17506 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17508 * composite.c (autocmp_chars): Don't reset point. That is done by
17509 restore_point_unwind (Bug#5984).
17511 2011-08-07 Juri Linkov <juri@jurta.org>
17513 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17514 to show the arg `TIME' instead of `TIMEVAL'.
17516 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17518 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17519 display property strides EOL and includes a newline, as in
17520 longlines-mode. (Bug#9254)
17521 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17522 word-wrap under bidirectional display. (Bug#9224)
17524 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17525 is non-zero, even if the data buffer is NULL. Fixes a crash in
17526 vertical-motion with longlines-mode. (Bug#9254)
17528 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17530 * bidi.c <bidi_cache_total_alloc>: Now static.
17531 (bidi_initialize): Initialize bidi_cache_total_alloc.
17533 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17536 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17537 amount allocated this far in `bidi_cache_total_alloc'.
17538 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17539 non-zero, only free the data buffer without restoring the cache
17540 contents. All callers changed.
17542 * dispextern.h (bidi_unshelve_cache): Update prototype.
17544 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17545 (move_it_in_display_line, move_it_to)
17546 (move_it_vertically_backward, move_it_by_lines): Replace the call
17547 to xfree to an equivalent call to bidi_unshelve_cache.
17548 (move_it_in_display_line_to): Fix logic of returning
17549 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17551 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17553 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17554 came from a string character with a `cursor' property. (Bug#9229)
17556 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17558 * Makefile.in (LIB_PTHREAD): New variable.
17559 (LIBES): Add LIB_PTHREAD (Bug#9216).
17561 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17562 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17564 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17566 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17568 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17570 * xterm.c (x_find_topmost_parent): New function.
17571 (x_set_frame_alpha): Find topmost parent window with
17572 x_find_topmost_parent and set the property there also (bug#9181).
17573 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17575 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17577 * callproc.c (Fcall_process): Avoid vfork clobbering
17578 the local vars buffer, coding_systems, current_dir.
17580 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17582 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17584 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17586 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17587 so that it is not optimized away.
17589 * xdisp.c (compute_display_string_pos): Remove unused local.
17591 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17593 Fix slow cursor motion and scrolling in large buffers with
17594 selective display, like Org Mode buffers. (Bug#9218)
17596 * dispextern.h (struct bidi_it): New member disp_prop_p.
17598 * xdisp.c: Remove one-slot cache of display string positions.
17599 (compute_display_string_pos): Accept an additional argument
17600 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17601 for a display string or property. If found, set DISP_PROP_P
17604 * bidi.c (bidi_fetch_char): Accept an additional argument
17605 DISP_PROP_P, and pass it to compute_display_string_pos.
17606 Only handle text covered by a display string if DISP_PROP_P is returned
17607 non-zero. All callers of bidi_fetch_char changed.
17609 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17611 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17613 2010-12-03 Don March <don@ohspite.net>
17615 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17616 last character M-[char] is translated to ESC [char] (bug#7541).
17618 2011-08-02 Kenichi Handa <handa@m17n.org>
17620 * lisp.h (uniprop_table): Extern it.
17622 * chartab.c (uniprop_table): Make it non-static.
17624 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17626 * xdisp.c (forward_to_next_line_start): Accept additional argument
17627 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17629 (reseat_at_next_visible_line_start): Use the bidi iterator state
17630 returned by forward_to_next_line_start to restore the state of
17631 it->bidi_it after backing up to previous newline. (Bug#9212)
17633 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17635 * regex.c (re_comp): Protoize.
17636 (re_exec): Fix return type.
17637 (regexec): Fix type of `ret'. (Bug#9203)
17639 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17641 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17642 This is needed if max-image-size is a floating-point number.
17644 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17646 * print.c (print_object): Print empty symbol as ##.
17648 * lread.c (read1): Read ## as empty symbol.
17650 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17652 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17653 setting frame foreground color (Bug#9175).
17654 (x_set_background_color): Likewise.
17656 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17657 contents (Bug#9176).
17658 (EmacsTooltip -init): Remove bezels and add shadows to
17661 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17662 or scroll bar (Bug#8470).
17664 * nsfont.m (nsfont_open): Remove assignment to voffset and
17665 unnecessary vars hshink, expand, hd, full_height, min_height.
17666 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17668 * nsterm.h (nsfont_info): Remove voffset field.
17670 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17672 Implement strike-through and overline on NextStep (Bug#8863).
17674 * nsfont.m (nsfont_open): Use underline position provided by font,
17675 instead of hard-coded value of 2.
17676 (nsfont_draw): Call ns_draw_text_decoration instead.
17678 * nsterm.h: Add declaration for ns_draw_text_decoration.
17680 * nsterm.m (ns_draw_text_decoration): New function for drawing
17681 underline, overline, and strike-through.
17682 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17683 ns_draw_text_decoration. Change treatment of cursor drawing to
17684 accommodate underlining, etc.
17686 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17688 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17691 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17693 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17694 Without this fix, if a signal arrives just after memory fills up,
17695 'malloc' might be invoked reentrantly.
17697 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17698 In other words, assume that every image size is allowed, on non-X
17699 hosts. This assumption is probably wrong, but it lets Emacs compile.
17701 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17703 * regex.c (re_iswctype): Convert return values to boolean.
17705 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17707 * xdisp.c (compute_display_string_pos): Don't use cached display
17708 string position if the buffer had its restriction changed.
17711 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17713 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17715 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17717 Integer signedness and overflow and related fixes. (Bug#9079)
17719 * bidi.c: Integer size and overflow fixes.
17720 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17721 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17722 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17723 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17724 (bidi_find_other_level_edge):
17725 Use ptrdiff_t instead of EMACS_INT where either will do.
17726 This works better on 32-bit hosts configured --with-wide-int.
17727 (bidi_cache_ensure_space): Check for size-calculation overflow.
17728 Use % rather than repeated addition, for better worst-case speed.
17729 Don't set bidi_cache_size until after xrealloc returns, because it
17731 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17732 (bidi_cache_ensure_space): Also check that the bidi cache size
17733 does not exceed that of the largest Lisp string or buffer. See Eli
17734 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17736 * alloc.c (__malloc_size_t): Remove.
17737 All uses replaced by size_t. See Andreas Schwab's note
17738 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17740 * image.c: Improve checking for integer overflow.
17741 (check_image_size): Assume that f is nonnull, since
17742 it is always nonnull in practice. This is one less thing to
17743 worry about when checking for integer overflow later.
17744 (x_check_image_size): New function, which checks for integer
17745 overflow issues inside X.
17746 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17747 This removes the need for a memory_full check.
17748 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17749 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17750 (xbm_read_bitmap_data): Change locals back to 'int', since
17751 their values must fit in 'int'.
17752 (xpm_load_image, png_load, tiff_load):
17753 Invoke x_create_x_image_and_pixmap earlier,
17754 to avoid much needless work if the image is too large.
17755 (tiff_load): Treat overly large images as if
17756 x_create_x_image_and_pixmap failed, not as malloc failures.
17757 (gs_load): Use x_check_image_size.
17759 * gtkutil.c: Omit integer casts.
17760 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17761 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17763 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17765 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17766 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17767 would wrongly return t on a 64-bit host.
17769 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17770 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17771 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17772 and therefore cause GCC to emit a bogus diagnostic in some cases.
17774 * image.c: Integer signedness and overflow and related fixes.
17775 This is not an exhaustive set of fixes, but it's time to
17776 record what I've got.
17777 (lookup_pixel_color, check_image_size): Remove redundant decls.
17778 (check_image_size): Don't assume that arbitrary EMACS_INT values
17779 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17780 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17781 (tiff_load, imagemagick_load_image):
17782 Check for overflow in size calculations.
17783 (x_create_x_image_and_pixmap): Remove unnecessary test for
17784 xmalloc returning NULL; that can't happen.
17785 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17786 (xpm_color_bucket): Use better integer hashing function.
17787 (xpm_cache_color): Don't possibly over-allocate memory.
17788 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17789 (gif_memory_source):
17790 Use ptrdiff_t, not int or size_t, to record sizes.
17791 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17792 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17793 either works, as we prefer signed integers.
17794 (tiff_read_from_memory, tiff_write_from_memory):
17795 Return tsize_t, not size_t, since that's what the TIFF API wants.
17796 (tiff_read_from_memory): Don't fail simply because the read would
17797 go past EOF; instead, return a short read.
17798 (tiff_load): Omit no-longer-needed casts.
17799 (Fimagemagick_types): Don't assume size fits into 'int'.
17801 Improve hashing quality when configured --with-wide-int.
17802 * fns.c (hash_string): New function, taken from sxhash_string.
17803 Do not discard information about ASCII character case; this
17804 discarding is no longer needed.
17805 (sxhash-string): Use it. Change sig to match it. Caller changed.
17806 * lisp.h: Declare it.
17807 * lread.c (hash_string): Remove, since we now use fns.c's version.
17808 The fns.c version returns a wider integer if --with-wide-int is
17809 specified, so this should help the quality of the hashing a bit.
17811 * emacs.c: Integer overflow minor fix.
17812 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17813 Define only if GNU_LINUX.
17814 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17816 * dispnew.c: Integer signedness and overflow fixes.
17817 Remove unnecessary forward decls, that were a maintenance hassle.
17818 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17820 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17821 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17822 (prepare_desired_row, line_draw_cost):
17823 Use int, not unsigned, where either works.
17824 (save_current_matrix, restore_current_matrix):
17825 Use ptrdiff_t, not size_t, where either works.
17826 (init_display): Check for overflow more accurately, and without
17827 relying on undefined behavior.
17829 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17830 Remove, replacing with the new symbols in lisp.h. All uses changed.
17831 * fileio.c (make_temp_name):
17832 * filelock.c (lock_file_1, lock_file):
17833 * xdisp.c (message_dolog):
17834 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17835 Use pMd etc. instead.
17836 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17837 replacing the pWIDE etc. symbols removed from editfns.c.
17839 * keyboard.h (num_input_events): Now uintmax_t.
17840 This is (very slightly) less likely to mess up due to wraparound.
17843 * buffer.c: Integer signedness fixes.
17844 (alloc_buffer_text, enlarge_buffer_text):
17845 Use ptrdiff_t rather than size_t when either will do, as we prefer
17848 * alloc.c: Integer signedness and overflow fixes.
17849 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17850 (__malloc_size_t): Default to size_t, not to int.
17851 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17852 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17853 Prefer ptrdiff_t to size_t when either would do, as we prefer
17855 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17856 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17857 Now const. Initialize with values that are in range even if char
17859 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17860 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17861 These functions do the right thing with sizes > 2**32.
17862 (check_depth): Now ptrdiff_t, not int.
17863 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17864 Adjust to new way of storing sizes. Check for size overflow bugs
17866 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17867 slightly wrong anyway, as it missed one instance of
17868 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17869 (refill_memory_reserve): Omit needless cast to size_t.
17870 (mark_object_loop_halt): Mark as externally visible.
17872 * xselect.c: Integer signedness and overflow fixes.
17873 (Fx_register_dnd_atom, x_handle_dnd_message):
17874 Use ptrdiff_t, not size_t, since we prefer signed.
17875 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17876 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17877 x_dnd_atoms_size and x_dnd_atoms_length.
17879 * doprnt.c: Prefer signed to unsigned when either works.
17881 * doprnt.c (doprnt):
17883 * xdisp.c (vmessage):
17884 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17885 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17886 prefer signed arithmetic to avoid comparison confusion.
17887 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17888 but is a bit tricky.
17890 Assume freestanding C89 headers, string.h, stdlib.h.
17891 * data.c, doprnt.c, floatfns.c, print.c:
17892 Include float.h unconditionally.
17893 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17894 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17895 * regex.c: Likewise for stddef.h, string.h.
17896 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17897 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17898 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17899 (STDC_HEADERS): Remove obsolete defines.
17900 * sysdep.c: Include limits.h unconditionally.
17902 Assume support for memcmp, memcpy, memmove, memset.
17903 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17904 * regex.c (memcmp, memcpy):
17905 Remove; we assume C89 now.
17907 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17908 (__malloc_safe_bcopy): Remove; no longer needed.
17910 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17911 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17912 well either way, and we prefer signed to unsigned.
17914 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17916 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17917 closes the connection while we're reading (bug#9182).
17919 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17921 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17922 are specified (Bug#9168).
17924 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17926 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17927 Found by GCC static checking and --with-wide-int on a 32-bit host.
17929 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17931 * xdisp.c (compute_display_string_pos): Fix logic of caching
17932 previous display string position. Initialize cached_prev_pos to
17933 -1. Fixes slow-down at the beginning of a buffer.
17935 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17937 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17938 for attrs[LFACE_FONTSET_INDEX].
17940 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17942 * xml.c (parse_region): Remove unused local
17943 that was recently introduced.
17945 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17947 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17948 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17950 * xdisp.c (move_it_in_display_line_to): Record the best matching
17951 position for TO_CHARPOS while scanning the line, and restore it on
17952 exit if none of the characters scanned was an exact match.
17953 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17954 when exact match is impossible due to invisible text, and the
17955 lines are truncated.
17957 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17959 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17962 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17964 Fix a significant slow-down of cursor motion with C-n, C-p,
17965 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17966 auto-repeat under bidi redisplay in fontified buffers.
17967 * xdisp.c (compute_stop_pos_backwards): New function.
17968 (next_element_from_buffer): Call compute_stop_pos_backwards to
17969 find a suitable prev_stop when we find ourselves before
17971 (reseat): Don't look for prev_stop, as that could mean a very long
17973 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17974 <cached_disp_overlay_modiff>: Cache for last found display string
17976 (compute_display_string_pos): Return the cached position if asked
17977 about the same buffer in the same area of character positions, and
17978 the buffer wasn't changed since the time the display string
17979 position was cached.
17981 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17983 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17984 is an integer, which is important for empty lines. (Bug#9149)
17986 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17988 * frame.c (Fmodify_frame_parameters): In tty case, update the
17989 default face if necessary (Bug#4238).
17991 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17993 * editfns.c (Fstring_to_char): No need to explain what a character
17994 is in the docstring (Bug#6576).
17996 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17998 * xml.c (parse_region): Make sure we always return a tree.
18000 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
18002 * xml.c (parse_region): If a document contains only comments,
18005 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
18007 * xml.c (make_dom): Return comments, too.
18009 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
18012 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
18013 and the surrounding thread.
18014 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
18015 rather than fgets, and retry after EINTR. Otherwise, 'emacs
18016 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
18018 * s/openbsd.h (BROKEN_SIGIO): Define.
18019 * unexelf.c (unexec) [__OpenBSD__]:
18020 Don't update the .mdebug section of the Alpha COFF symbol table.
18022 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
18024 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
18027 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
18029 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
18030 This fixes some race conditions on the permissions of any newly
18033 * alloc.c (valid_pointer_p): Use pipe, not open.
18034 This fixes some permissions issues when debugging.
18036 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
18037 If fchown fails to set both uid and gid, try to set just gid,
18038 as that is sometimes allowed. Adjust the file's mode to eliminate
18039 setuid or setgid bits that are inappropriate if fchown fails.
18041 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
18043 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
18044 to compare Lisp_Objects.
18045 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
18046 global_gnutls_log_level, don't mistake it for a Lisp_Object.
18047 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
18049 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
18051 * lread.c (read_integer): Unread even EOF character.
18052 (read1): Likewise. Properly record start position of symbol.
18054 * lread.c (read1): Read `#:' as empty uninterned symbol if no
18055 symbol character follows.
18057 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
18059 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
18060 This works around a problem with the previous change to Fcopy_file.
18061 Recent glibc declares fchown with __attribute__((warn_unused_result)),
18062 and without this change, GCC might complain about discarding
18063 fchown's return value.
18065 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
18067 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
18069 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
18071 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
18073 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
18075 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18076 it's used from the C level.
18078 * process.c: Use the same condition for POLL_FOR_INPUT in both
18079 keyboard.c and process.c (bug#1858).
18081 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18083 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18084 (Fgnutls_boot): Use it.
18086 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18088 * doc.c (Fsubstitute_command_keys): Revert last change.
18090 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18092 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18093 quotes the next character, and doesn't affect other longer
18094 sequences (bug#8935).
18096 * lread.c (syms_of_lread): Clarify that is isn't only
18097 `eval-buffer' and `eval-defun' that's affected by
18098 `lexical-binding' (bug#8460).
18100 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18102 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18103 bidi redisplay when a line includes both an image and is truncated.
18105 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18107 Fix minor problems found by static checking.
18108 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18109 (elsz): Now a signed constant, not a size_t var. We prefer signed
18110 types to unsigned, to avoid integer comparison confusion. Without
18111 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18112 "cannot optimize loop, the loop counter may overflow", a symptom
18114 * indent.c (Fvertical_motion): Mark locals as initialized.
18115 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18117 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18119 * search.c (Fre_search_backward): Mention `case-fold-search' in
18120 all the re_search_* functions (bug#8138).
18122 * keyboard.c (Fopen_dribble_file): Document when the file is
18125 2011-07-14 Eli Zaretskii <eliz@gnu.org>
18127 * bidi.c (bidi_dump_cached_states): Fix format of displaying
18130 Support bidi reordering of display and overlay strings.

18132 (compute_display_string_end): Accept additional argument STRING.
18133 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
18134 (reseat_to_string): Initialize bidi_it->string.s and
18135 bidi_it->string.schars.
18136 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
18137 NULL (avoids a crash in bidi_paragraph_init).
18138 Initialize itb.string.lstring.
18139 (init_iterator): Call bidi_init_it only of a valid
18140 buffer position was specified. Initialize paragraph_embedding to
18142 (reseat_to_string): Initialize the bidi iterator.
18143 (display_string): If we need to ignore text properties of
18144 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18145 original value of -1 will not work with bidi.)
18146 (compute_display_string_pos): First arg is now struct
18147 `text_pos *'; all callers changed. Support display properties on
18149 (compute_display_string_end): Support display properties on Lisp
18151 (init_iterator, reseat_1, reseat_to_string): Initialize the
18152 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18153 when iterating on a string not from display properties).
18154 (compute_display_string_pos, compute_display_string_end):
18155 Fix calculation of the object to scan. Fixes an error when using
18157 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18158 base_level_stop; instead, set base_level_stop to BEGV.
18159 Fixes crashes in vertical-motion.
18160 (next_element_from_buffer): Improve commentary for when
18161 the iterator is before prev_stop.
18162 (init_iterator): Initialize bidi_p from the default value of
18163 bidi-display-reordering, not from buffer-local value. Use the
18164 buffer-local value only if initializing for buffer iteration.
18165 (handle_invisible_prop): Support invisible properties on strings
18166 that are being bidi-reordered.
18167 (set_iterator_to_next): Support bidi reordering of C strings and
18169 (next_element_from_string): Support bidi reordering of Lisp
18171 (handle_stop_backwards): Support Lisp strings as well.
18172 (display_string): Support display of R2L glyph rows.
18173 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18174 (init_iterator): Don't initialize it->bidi_p for strings
18176 (reseat_to_string): Initialize it->bidi_p for strings here.
18177 (next_element_from_string, next_element_from_c_string)
18178 (next_element_from_buffer): Add xassert's for correspondence
18179 between IT's object being iterated and it->bidi_it.string
18181 (face_before_or_after_it_pos): Support bidi iteration.
18182 (next_element_from_c_string): Handle the case of the first string
18183 character that is not the first one in the visual order.
18184 (get_visually_first_element): New function, refactored from common
18185 parts of next_element_from_buffer, next_element_from_string, and
18186 next_element_from_c_string.
18187 (tool_bar_lines_needed, redisplay_tool_bar)
18188 (display_menu_bar): Force left-to-right direction. Add a FIXME
18189 comment for making that be controlled by a user option.
18190 (push_it, pop_it): Save and restore the state of the
18191 bidi iterator. Save and restore the bidi_p flag.
18192 (pop_it): Iterate out of display property for string iteration as
18194 (iterate_out_of_display_property): Support iteration over strings.
18195 (handle_single_display_spec): Set up it->bidi_it for iteration
18196 over a display string, and call bidi_init_it.
18197 (handle_single_display_spec, next_overlay_string)
18198 (get_overlay_strings_1, push_display_prop): Set up the bidi
18199 iterator for displaying display or overlay strings.
18200 (forward_to_next_line_start): Don't use the shortcut if
18202 (back_to_previous_visible_line_start): If handle_display_prop
18203 pushed the iterator stack, restore the internal state of the bidi
18204 iterator by calling bidi_pop_it same number of times.
18205 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18206 and we are bidi-iterating, don't decrement the iterator position;
18207 instead, set the first_elt flag in the bidi iterator, to produce
18209 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18210 (push_display_prop): xassert that we are iterating a buffer.
18211 (push_it, pop_it): Save and restore paragraph_embedding member.
18212 (handle_single_display_spec, next_overlay_string)
18213 (get_overlay_strings_1, reseat_1, reseat_to_string)
18214 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18215 correctly. Don't assume unibyte strings are not bidi-reordered.
18216 (compute_display_string_pos)
18217 (compute_display_string_end): Fix handling the case of C string.
18218 (push_it, pop_it): Save and restore from_disp_prop_p.
18219 (handle_single_display_spec, push_display_prop): Set the
18220 from_disp_prop_p flag.
18221 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
18222 (pop_it): Call iterate_out_of_display_property only if we are
18223 popping after iteration over a string that came from a display
18224 property. Fix a typo in popping stretch info. Add an assertion
18225 for verifying that the iterator position is in sync with the bidi
18227 (handle_single_display_spec, get_overlay_strings_1)
18228 (push_display_prop): Fix initialization of paragraph direction for
18229 string when that of the parent object is not yet determined.
18230 (reseat_1): Call bidi_init_it to resync the bidi

18678 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
18680 Random fixes. E.g., (random) never returned negative values.
18681 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18682 subseconds part to the entropy, as that's a bit more random.
18683 Prefer signed to unsigned, since the signedness doesn't matter and
18684 in general we prefer signed. When given a limit, use a
18685 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18686 latter isn't right if USE_2_TAGS_FOR_INTS.
18687 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18688 not 0..VALMASK. Don't discard "excess" bits that random () returns.
18690 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
18692 * textprop.c (text_property_stickiness):
18693 Obey Vtext_property_default_nonsticky.

18700 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18701 This is more efficient than Ffile_directory_p and avoids a minor race.
18703 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18705 * buffer.c (Foverlay_put): Say what the return value is
18708 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18709 is a directory before asking whether to use the file name
18711 (barf_or_query_if_file_exists): Make the "File is a directory"
18712 error be more correct.
18714 * fns.c (Frequire): Remove the mention of the .gz files, since
18715 that's installation-specific, but keep the mention of
18716 `get-load-suffixes'.
18718 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
18720 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18725 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
18726 (syms_of_gnutls): Remove duplicate DEFSYM for
18727 Qgnutls_bootprop_verify_hostname_error, an error for
18728 Qgnutls_bootprop_verify_error (which is no longer used).
18730 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18731 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18732 Also (re)move comments that are misplaced or no longer relevant.
18734 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
18736 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

18740 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
18741 and background color parameters if they have been changed.

18761 * lread.c (syms_of_lread): Mention single symbols defined by
18762 `defvar' or `defconst' (bug#7154).
18764 * fns.c (Frequire): Mention .el.gz files (bug#7314).
18765 (Frequire): Mention get-load-suffixes.
18767 2011-07-02 Martin Rudalics <rudalics@gmx.at>

18795 (syms_of_keymap): Defsubr make-composed-keymap.
18796 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

18833 * eval.c (struct backtrace): Simplify and port the data structure.
18834 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18835 signed bit field, as this assumption is not portable and it makes
18836 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18837 "char debug_on_exit : 1" as this is not portable either; instead,
18838 use the portable "unsigned int debug_on_exit : 1". Remove unused
18839 member evalargs. Remove obsolete comments about cc bombing out.
18841 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
18843 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

18911 (emacs_fixed_get_preferred_height): Use min_width/height from
18912 frames size_hint to set minimum and natural (Bug#8919).
18913 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18914 and use min_width/height from frames size_hint to set
18915 min_width/height (Bug#8919).

19007 * print.c (printchar, strout): Check for string overflow.
19008 (PRINTPREPARE, printchar, strout):
19009 Don't set size unless allocation succeeds.
19011 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
19012 for sizes. Check for string overflow more accurately.

19016 * keyboard.h (struct keyboard.kbd_macro_bufsize):
19017 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

19026 (read_integer): Radix is now EMACS_INT, not int,
19027 to improve quality of diagnostics for out-of-range radices.
19028 Calculate buffer size correctly for out-of-range radices.
19029 (read1): Check for integer overflow in radices, and in
19030 read-circle numbers.
19031 (read_escape): Avoid int overflow.
19032 (Fload, openp, read_buffer_size, read1)
19033 (substitute_object_recurse, read_vector, read_list, map_obarray):

19056 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
19057 The following patches are for when GLYPH_DEBUG && !XASSERT.
19058 * dispextern.h (trace_redisplay_p, dump_glyph_string):
19059 * dispnew.c (flush_stdout):
19060 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
19061 Mark as externally visible.
19062 * dispnew.c (check_window_matrix_pointers): Now static.
19063 * dispnew.c (window_to_frame_vpos):
19064 * xfns.c (unwind_create_frame):

19071 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
19073 (debug_method_add): Use va_list and vsprintf rather than relying
19074 on undefined behavior with wrong number of arguments.
19075 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19076 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19077 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19078 since we're not interested in debugging glyphs with old libraries.
19079 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19080 GCC 4.6.0's static checking.
19082 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

19101 (.bitmaps_last, struct x_output.icon_bitmap):
19102 Use ptrdiff_t, not int, for bitmap indexes.
19103 (x_allocate_bitmap_record): Check for size overflow.
19104 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
19106 Use ptrdiff_t, not int, for overlay counts.
19107 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
19108 * editfns.c (overlays_around, get_pos_property):
19109 * textprop.c (get_char_property_and_overlay):
19110 * xdisp.c (next_overlay_change, note_mouse_highlight):
19111 * xfaces.c (face_at_buffer_position):
19112 * buffer.c (OVERLAY_COUNT_MAX): New macro.
19113 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
19114 (Fnext_overlay_change, Fprevious_overlay_change)
19115 (mouse_face_overlay_overlaps, Foverlays_in):
19116 Use ptrdiff_t, not int, for sizes.
19117 (overlays_at, overlays_in): Check for size-calculation overflow.
19119 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
19121 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19122 (x_session_initialize): Do not assume string length fits in int.
19124 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19125 This is unlikely, but can occur if DPI is outlandish.
19127 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19128 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19130 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19131 * xrdb.c (magic_file_p, search_magic_path):
19132 Omit last arg SUFFIX; it was always 0. All callers changed.
19133 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19135 * xfont.c (xfont_match): Avoid need for strlen.
19137 * xfns.c: Don't assume strlen fits in int.
19138 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
19140 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19141 not unsigned long, as we prefer signed integers. All callers changed.
19142 Detect integer overflow in repeat count.
19143 (message_dolog): Don't assume print length fits in 39 bytes.
19144 (display_mode_element): Don't assume strlen fits in int.
19146 * termcap.c: Don't assume sizes fit in int and never overflow.
19147 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19148 (gobble_line): Check for size-calculation overflow.
19150 * minibuf.c (Fread_buffer):
19151 * lread.c (intern, intern_c_string):
19152 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19153 Don't assume string length fits in int.
19155 * keyboard.c (parse_tool_bar_item):
19156 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19158 * font.c: Don't assume string length fits in int.
19159 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
19160 Use ptrdiff_t, not int.
19161 (font_intern_prop): Don't assume string length fits in int.
19162 Don't assume integer property fits in fixnum.
19163 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19165 * filelock.c: Fix some buffer overrun and integer overflow issues.
19166 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19167 Reformulate so as not to need the command string.
19168 Invoke gzip -cd rather than gunzip, as it's more portable.
19169 (lock_info_type, lock_file_1, lock_file):
19170 Don't assume pid_t and time_t fit in unsigned long.
19171 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19172 (current_lock_owner): Prefer signed type for sizes.
19173 Use memcpy, not strncpy, where memcpy is what is really wanted.
19174 Don't assume (via atoi) that time_t and pid_t fit in int.
19175 Check for time_t and/or pid_t out of range, e.g., via a network share.
19176 Don't alloca where an auto var works fine.
19178 * fileio.c: Fix some integer overflow issues.
19179 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19180 Don't assume string length fits in int.
19181 (directory_file_name): Don't assume string length fits in long.
19182 (make_temp_name): Don't assume pid fits in int, or that its print
19183 length is less than 20.
19185 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19187 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19189 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19191 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19192 We prefer signed integers, even for size calculations.
19194 * emacs.c: Don't assume string length fits in 'int'.
19195 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19196 (main): Don't invoke strlen when not needed.
19198 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19199 (XD_DEBUG_MESSAGE): Don't waste a byte.
19201 * callproc.c (getenv_internal_1, getenv_internal)
19202 (Fgetenv_internal):
19203 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19205 * lread.c (invalid_syntax): Omit length argument.
19206 All uses changed. This doesn't fix a bug, but it simplifies the
19207 code away from its former Hollerith-constant appearance, and it's
19208 one less 'int' to worry about when looking at integer-overflow issues.
19209 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19211 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19212 This didn't break anything, but it didn't help either.
19213 It's confusing to put a bogus integer in a place where the actual
19214 value does not matter.
19215 (LIST_END_P): Remove unused macro and its bogus comment.
19216 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19218 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19219 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19221 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19222 We prefer signed types, and the value cannot exceed the EMACS_INT
19223 range anyway (because otherwise the length would not be representable).
19224 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19225 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19226 This avoids a GCC warning when WIDE_EMACS_INT.
19228 * indent.c (sane_tab_width): New function.
19229 (current_column, scan_for_column, Findent_to, position_indentation)
19230 (compute_motion): Use it. This is just for clarity.
19231 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19233 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19235 * lisp.h (lint_assume): New macro.
19236 * composite.c (composition_gstring_put_cache):
19237 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19239 * editfns.c, insdel.c:
19240 Omit unnecessary forward decls, to simplify future changes.
19242 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19244 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19246 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19247 Use much-faster test for byte-length change.
19248 Don't assume string byte-length fits in 'int'.
19249 Check that character arg fits in 'int'.
19250 (mapcar1): Declare byte as byte, for clarity.
19252 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19254 * fns.c (concat): Catch string overflow earlier.
19255 Do not rely on integer wraparound.
19257 * dispextern.h (struct it.overlay_strings_charpos)
19258 (struct it.selective): Now EMACS_INT, not int.
19259 * xdisp.c (forward_to_next_line_start)
19260 (back_to_previous_visible_line_start)
19261 (reseat_at_next_visible_line_start, next_element_from_buffer):
19262 Don't arbitrarily truncate the value of 'selective' to int.
19264 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19266 * composite.c: Don't truncate sizes to 'int'.
19267 (composition_gstring_p, composition_reseat_it)
19268 (composition_adjust_point): Use EMACS_INT, not int.
19269 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19270 not EMACS_UINT, for indexes.
19272 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19274 * buffer.c: Include <verify.h>.
19275 (struct sortvec.priority, struct sortstr.priority):
19276 Now EMACS_INT, not int.
19277 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19278 (struct sortstr.size, record_overlay_string)
19279 (struct sortstrlist.size, struct sortlist.used):
19280 Don't truncate size to int.
19281 (record_overlay_string): Check for size-calculation overflow.
19282 (init_buffer_once): Check at compile-time, not run-time.
19284 2011-06-22 Jim Meyering <meyering@redhat.com>
19286 Don't leak an XBM-image-sized buffer
19287 * image.c (xbm_load): Free the image buffer after using it.
19289 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19292 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19293 that Sun C diagnosed.
19294 * fns.c (secure_hash): Fix pointer signedness issue.
19295 * intervals.c (static_offset_intervals): New function.
19296 (offset_intervals): Use it.
19298 2011-06-21 Leo Liu <sdl.web@gmail.com>
19301 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19304 * fns.c (secure_hash): Rename from crypto_hash_function and change
19305 the first arg to accept symbols.
19306 (Fsecure_hash): New primitive.
19307 (syms_of_fns): New symbols.
19309 2011-06-20 Deniz Dogan <deniz@dogan.se>
19311 * process.c (Fset_process_buffer): Clarify return value in
19314 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19316 * dispnew.c (add_window_display_history): Use BVAR.
19318 * xdisp.c (debug_method_add): Use BVAR.
19319 (check_window_end, dump_glyph_matrix, dump_glyph)
19320 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19322 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19325 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19326 check till after the cache is created in init_frame_faces.
19328 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19330 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19332 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19334 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19335 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19336 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19338 Improve buffer-overflow checking (Bug#8873).
19339 * fileio.c (Finsert_file_contents):
19340 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19341 Remove the old (too-loose) buffer overflow checks.
19342 They weren't needed, since make_gap checks for buffer overflow.
19343 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19344 The old code merely checked for Emacs fixnum overflow, and relied
19345 on undefined (wraparound) behavior. The new code avoids undefined
19346 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19348 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19349 Tune. Don't use wider integers than needed. Don't use alloca.
19350 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19352 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19354 * insdel.c, lisp.h (buffer_overflow): New function.
19355 (insert_from_buffer_1, replace_range, replace_range_2):
19356 * insdel.c (make_gap_larger):
19357 * editfns.c (Finsert_char):
19358 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19360 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19362 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19364 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19366 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19367 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19369 * fileio.c: Don't assume EMACS_INT fits in off_t.
19370 (emacs_lseek): New static function.
19371 (Finsert_file_contents, Fwrite_region): Use it.
19372 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19374 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19376 * fns.c: Don't overflow int when computing a list length.
19377 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19378 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19379 truncation on 64-bit hosts. Check for QUIT every
19380 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19381 faster and is responsive enough.
19382 (Flength): Report an error instead of overflowing an integer.
19383 (Fsafe_length): Return a float if the value is not representable
19384 as a fixnum. This shouldn't happen except in contrived situations.
19385 (Fnthcdr, Fsort): Don't assume list length fits in int.
19386 (Fcopy_sequence): Don't assume vector length fits in int.
19388 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19389 (header_size, word_size): New constants.
19390 (allocate_vectorlike): Don't check size overflow here.
19391 (allocate_vector): Check it here instead, since this is the only
19392 caller of allocate_vectorlike that could cause overflow.
19393 Check that the new vector's length is representable as a fixnum.
19395 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19396 The previous code was bogus. For example, next_almost_prime (32)
19397 returned 39, which is undesirable as it is a multiple of 3; and
19398 next_almost_prime (24) returned 25, which is a multiple of 5 so
19399 why was the code bothering to check for multiples of 7?
19401 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19403 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19405 Variadic C functions now count arguments with ptrdiff_t.
19406 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19407 Back then I didn't know that the Emacs coding style prefers signed int.
19408 Also, in the meantime I found a few more instances where arguments
19409 were being counted with int, which may truncate counts on 64-bit
19410 machines, or EMACS_INT, which may be unnecessarily wide.
19411 * lisp.h (struct Lisp_Subr.function.aMANY)
19412 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19413 Arg counts are now ptrdiff_t, not size_t.
19414 All variadic functions and their callers changed accordingly.
19415 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19416 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19417 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19418 * callint.c (Fcall_interactively): Check arg count for overflow,
19419 to avoid potential buffer overrun. Use signed char, not 'int',
19420 for 'varies' array, so that we needn't bother to check its size
19421 calculation for overflow.
19422 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19423 * eval.c (apply_lambda):
19424 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19425 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19426 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19428 * callint.c (Fcall_interactively): Don't use index var as event count.
19430 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19431 * mem-limits.h (SIZE): Remove; no longer used.
19433 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19435 Remove unnecessary casts.
19436 * xterm.c (x_term_init):
19437 * xfns.c (x_set_border_pixel):
19438 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19439 These aren't needed now that we assume ANSI C.
19441 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19442 It's more likely to cause problems (due to unsigned overflow)
19445 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19447 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19449 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19451 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19453 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19455 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19457 GLYPH_CODE_FACE returns EMACS_INT, not int.
19458 * dispextern.h (merge_faces):
19459 * xfaces.c (merge_faces):
19460 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19461 Don't assume EMACS_INT fits in int.
19463 * character.h (CHAR_VALID_P): Remove unused parameter.
19464 * fontset.c, lisp.h, xdisp.c: All uses changed.
19466 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19468 * fns.c (concat): Minor tuning based on overflow analysis.
19469 This doesn't fix any bugs. Use int to hold character, instead
19470 of constantly refetching from Emacs object. Use XFASTINT, not
19471 XINT, for value known to be a character. Don't bother comparing
19472 a single byte to 0400, as it's always less.
19474 * floatfns.c (Fexpt):
19475 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19477 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19480 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19482 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19483 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19484 incorrectly succeed when S was a string, because 4294967386 was
19485 truncated before it was used.
19487 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19488 Otherwise, an out-of-range integer could cause undefined behavior
19491 * composite.c: Use int, not EMACS_INT, for characters.
19492 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19493 EMACS_INT, for values that are known to be in character range.
19494 This doesn't fix any bugs but is the usual style inside Emacs and
19495 may generate better code on 32-bit machines.
19497 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19498 This is for reasons similar to the recent CHAR_STRING fix.
19499 * charset.c (Fencode_char): Check that character arg is actually
19500 a character. Pass an int to ENCODE_CHAR.
19501 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19502 wider than 'int', as a compile-time check to prevent future regressions
19505 * character.c (char_string): Remove unnecessary casts.
19507 Make sure a 64-bit char is never passed to CHAR_STRING.
19508 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19509 by silently ignoring the top 32 bits, allowing some values
19510 that were far too large to be valid characters.
19511 * character.h: Include <verify.h>.
19512 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19513 arguments are no wider than unsigned, as a compile-time check
19514 to prevent future regressions in this area.
19516 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19517 (Fsubst_char_in_region):
19519 * xdisp.c (decode_mode_spec_coding):
19520 Adjust to CHAR_STRING's new requirement.
19521 * editfns.c (Finsert_char, Fsubst_char_in_region):
19522 * fns.c (concat): Check that character args are actually
19523 characters. Without this test, these functions did the wrong
19524 thing with wildly out-of-range values on 64-bit hosts.
19526 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19527 These casts should not be needed on 32-bit hosts, either.
19528 * keyboard.c (read_char):
19529 * lread.c (Fload): Remove casts to unsigned.
19531 * lisp.h (UNSIGNED_CMP): New macro.
19532 This fixes comparison bugs on 64-bit hosts.
19533 (ASCII_CHAR_P): Use it.
19534 * casefiddle.c (casify_object):
19535 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19536 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19537 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19538 * dispextern.h (FACE_FROM_ID):
19539 * keyboard.c (read_char): Use UNSIGNED_CMP.
19541 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19542 not to EMACS_INT, to avoid GCC warning.
19544 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19546 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19547 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and

20183 instead of using explicit *_CHAR codes.
20184 (bidi_resolve_explicit, bidi_resolve_weak):

20193 (bidi_level_of_next_char): Don't try to lookup the cache for the
20194 next/previous character if nothing is cached there yet, or if we
20195 were just reseat()'ed to a new position.
20197 * xdisp.c (set_cursor_from_row): Set start and stop points
20198 according to the row's direction when priming the loop that looks

20201 (display_prop_intangible_p): Reimplement to call
20202 handle_display_spec instead of single_display_spec_intangible_p.
20203 Accept 3 additional arguments needed by handle_display_spec.

20207 lists with the argument STRING its top-level element.
20208 (display_prop_string_p): Fix the condition for processing a

20212 (compute_display_string_pos): Accept additional argument
20213 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20214 value of a `display' property is a "replacing spec".
20215 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20216 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20217 the display property, but just return a value indicating whether
20218 the display property will replace the characters it covers.
20219 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20220 frame_window_p members of struct bidi_it.

20246 * gnutls.c: Use Emacs's memory allocators.
20247 Without this change, the gnutls library would invoke malloc etc.
20248 directly, which causes problems on non-SYNC_INPUT hosts, and which
20249 runs afoul of improving memory_full behavior. (Bug#8761)
20250 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20251 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20252 xfree instead of the default malloc, realloc, free.
20253 (Fgnutls_boot): No need to check for memory allocation failure,
20254 since xmalloc does that for us.

20277 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20278 * alloc.c (allocate_vectorlike):
20279 Check for overflow in vector size calculations.
20280 * ccl.c (ccl_driver):
20281 Check for overflow when converting EMACS_INT to int.

20283 need to be updated by these changes.
20284 * fns.c (make_hash_table, maybe_resize_hash_table):
20285 Check for integer overflow with large hash tables.
20286 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20287 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20288 (SXHASH_REDUCE): New macro.
20289 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20290 Use it instead of discarding useful hash info with large hash values.
20291 (sxhash_float): New function.
20292 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20293 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20294 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20295 Rewrite to use FIXNUM_BITS, as this simplifies things.
20296 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20297 Adjust signatures to match updated version of code.
20298 (consing_since_gc): Now EMACS_INT, since a single hash table can
20299 use more than INT_MAX bytes.

20348 Make it possible to run ./temacs.
20350 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,

20420 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20422 Integer overflow fixes.
20424 * dbusbind.c: Serial number integer overflow fixes.
20425 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20426 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20427 to hold a serial number that is too large for a fixnum.
20428 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20429 Check for serial numbers out of range. Decode any serial number
20430 that was so large that it became a float. (Bug#8722)
20432 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20433 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20434 Use XFASTINT rather than XUINT when numbers are nonnegative.
20435 (xd_append_arg, Fdbus_method_return_internal):
20436 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20437 arguments, check that Lisp number is nonnegative, rather than
20438 silently wrapping negative numbers around. (Bug#8722)
20439 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20442 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20444 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20446 ccl: Add integer overflow checks.
20447 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20448 (IN_INT_RANGE): New macros.
20449 (ccl_driver): Use them to check for integer overflow when
20450 decoding a CCL program. Many of the new checks are whether XINT (x)
20451 fits in int; it doesn't always, on 64-bit hosts. The new version
20452 doesn't catch all possible integer overflows, but it's an
20453 improvement. (Bug#8719)
20455 * alloc.c (make_event_array): Use XINT, not XUINT.
20456 There's no need for unsigned here.
20458 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20459 This follows up to the 2011-05-06 change that substituted uintptr_t
20460 for EMACS_INT. This case wasn't caught back then.
20462 Rework Fformat to avoid integer overflow issues.
20463 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20464 now (part of C89). Include <verify.h>.
20465 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20466 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20467 (Fformat): Avoid the prepass trying to compute sizes; it was only
20468 approximate and thus did not catch overflow reliably. Instead, walk
20469 through the format just once, formatting and computing sizes as we go,
20470 checking for integer overflow at every step, and allocating a larger
20471 buffer as needed. Keep track separately whether the format is
20472 multibyte. Keep only the most-recently calculated precision, rather
20473 than them all. Record whether each argument has been converted to
20474 string. Use EMACS_INT, not int, for byte and char and arg counts.
20475 Support field widths and precisions larger than INT_MAX. Avoid
20476 sprintf's undefined behavior with conversion specifications such as %#d
20477 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20478 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20479 formatting out-of-range floating point numbers with int
20480 formats. (Bug#8668)
20482 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20484 * data.c: Avoid integer truncation in expressions involving floats.
20485 * data.c: Include <intprops.h>.
20486 (arith_driver): When there's an integer overflow in an expression
20487 involving floating point, convert the integers to floating point
20488 so that the resulting value does not suffer from catastrophic
20489 integer truncation. For example, on a 64-bit host (* 4
20490 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20491 Do not rely on undefined behavior after integer overflow.
20493 merge count_size_as_multibyte, parse_str_to_multibyte
20494 * character.c, character.h (count_size_as_multibyte):
20495 Rename from parse_str_to_multibyte; all uses changed.
20496 Check for integer overflow.
20497 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20498 since it's now a duplicate of the other. This is more of
20499 a character than a buffer op, so better that it's in character.c.
20500 * fns.c, print.c: Adjust to above changes.
20502 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20504 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20506 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20508 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20509 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20510 (x_clipboard_manager_save): Now static.
20511 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20513 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20514 (crypto_hash_function): Now static.
20515 Fix pointer signedness problems. Avoid unnecessary initializations.
20517 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20519 * termhooks.h (Vselection_alist): Make it terminal-local.
20521 * terminal.c (create_terminal): Initialize it.
20523 * xselect.c: Support for clipboard managers.
20524 (Vselection_alist): Move to termhooks.h as terminal-local var.
20525 (LOCAL_SELECTION): New macro.
20526 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20527 (symbol_to_x_atom): Remove gratuitous arg.
20528 (x_handle_selection_request, lisp_data_to_selection_data)
20529 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20530 (x_own_selection, x_get_local_selection, x_convert_selection):
20531 New arg, specifying work frame. Use terminal-local Vselection_alist.
20532 (some_frame_on_display): Delete unused function.
20533 (Fx_own_selection_internal, Fx_get_selection_internal)
20534 (Fx_disown_selection_internal, Fx_selection_owner_p)
20535 (Fx_selection_exists_p): New optional frame arg.
20536 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20537 (x_handle_selection_clear): Don't treat other terminals with the
20538 same keyboard specially. Use the terminal-local Vselection_alist.
20539 (x_clear_frame_selections): Use Frun_hook_with_args.
20541 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20543 * xterm.h: Add support for those atoms.
20545 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20547 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20548 (converted_selections, conversion_fail_tag): New global variables.
20549 (x_selection_request_lisp_error): Free the above.
20550 (x_get_local_selection): Remove unnecessary code.
20551 (x_reply_selection_request): Args changed; handle arbitrary array
20552 of converted selections stored in converted_selections.
20553 Separate the XChangeProperty and SelectionNotify steps.
20554 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20555 (x_convert_selection): New function.
20556 (x_handle_selection_event): Simplify.
20557 (x_get_foreign_selection): Don't ignore incoming requests while
20558 waiting for an answer; this will fail when we implement
20559 SAVE_TARGETS, and seems unnecessary anyway.
20560 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20561 (Vx_sent_selection_functions): Doc fix.
20563 2011-05-26 Leo Liu <sdl.web@gmail.com>
20565 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20567 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20569 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20571 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20572 for fringe update if it has periodic bitmap.
20573 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20574 and fringe_bitmap_periodic_p.
20576 * fringe.c (get_fringe_bitmap_data): New function.
20577 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20578 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20579 row. Mark glyph row for fringe update if periodicity changed.
20581 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20582 for fringe update unless it has periodic bitmap.
20584 2011-05-25 Kenichi Handa <handa@m17n.org>
20586 * xdisp.c (get_next_display_element): Set correct it->face_id for
20587 a static composition.
20589 2011-05-24 Leo Liu <sdl.web@gmail.com>
20592 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20594 * fns.c (crypto_hash_function, Fsha1): New function.
20595 (Fmd5): Use crypto_hash_function.
20596 (syms_of_fns): Add Ssha1.
20598 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20600 * gnutls.c: Remove unused macros.
20601 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20602 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20603 Remove macros that are defined and never used.
20604 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20606 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20608 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20609 (Fx_get_selection_internal): Minor cleanup.
20610 (Fx_own_selection_internal): Rename arguments for consistency with
20613 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20615 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20617 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20619 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20621 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20623 * dispnew.c (scrolling_window): Don't exclude the case that the
20624 last enabled row in the desired matrix touches the bottom boundary.
20626 2011-05-21 Glenn Morris <rgm@gnu.org>
20628 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20629 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20630 and add some more files.
20632 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20634 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20635 report_file_error introduced by the change from 2011-05-07.
20637 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20639 * systime.h (Time): Define only if emacs is defined.
20640 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20641 where the include path doesn't have X11/X.h by default. See
20642 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20644 2011-05-20 Kenichi Handa <handa@m17n.org>
20646 * composite.c (find_automatic_composition): Fix previous change.
20648 2011-05-20 Glenn Morris <rgm@gnu.org>
20650 * lisp.mk: New file, split from Makefile.in.
20651 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20652 (shortlisp): Remove.
20653 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20655 2011-05-19 Glenn Morris <rgm@gnu.org>
20657 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20658 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20659 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20660 (lisp): Set the order to that of loadup.el.
20661 (shortlisp): Make it a copy of $lisp.
20662 (SOME_MACHINE_LISP): Remove.
20663 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20664 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20666 2011-05-18 Kenichi Handa <handa@m17n.org>
20668 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20669 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20670 (find_automatic_composition): Mostly rewrite for efficiency.
20672 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20674 * makefile.w32-in: Update dependencies.
20676 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20678 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20679 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20681 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20683 Fix some integer overflow issues, such as string length overflow.
20685 * insdel.c (count_size_as_multibyte): Check for string overflow.
20687 * character.c (lisp_string_width): Check for string overflow.
20688 Use EMACS_INT, not int, for string indexes and lengths; in
20689 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20690 the resulting string length overflows an EMACS_INT; instead,
20691 report a string overflow if no precision given. When checking for
20692 precision exhaustion, use a check that cannot possibly have
20693 integer overflow. (Bug#8675)
20694 * character.h (lisp_string_width): Adjust to new signature.
20696 * alloc.c (string_overflow): New function.
20697 (Fmake_string): Use it. This doesn't change behavior, but saves
20698 a few bytes and will simplify future changes.
20699 * character.c (string_escape_byte8): Likewise.
20700 * lisp.h (string_overflow): New decl.
20702 Fixups, following up to the user-interface timestamp change.
20703 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20704 for UI timestamps, instead of unsigned long.
20705 * msdos.c (mouse_get_pos): Likewise.
20706 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20707 * w32gui.h (Time): Define by including "systime.h" rather than by
20708 declaring it ourselves. (Bug#8664)
20710 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20711 * image.c (clear_image_cache): Likewise.
20713 * term.c (term_mouse_position): Don't assume time_t wraparound.
20715 Be more systematic about user-interface timestamps.
20716 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20717 and sometimes 'EMACS_UINT', to represent these timestamps.
20718 This change causes it to use 'Time' uniformly, as that's what X uses.
20719 This makes the code easier to follow, and makes it easier to catch
20720 integer overflow bugs such as Bug#8664.
20721 * frame.c (Fmouse_position, Fmouse_pixel_position):
20722 Use Time, not unsigned long, for user-interface timestamps.
20723 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20724 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20725 * keyboard.h (last_event_timestamp): Likewise.
20726 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20727 * menu.h (xmenu_show): Likewise.
20728 * term.c (term_mouse_position): Likewise.
20729 * termhooks.h (struct input_event.timestamp): Likewise.
20730 (struct terminal.mouse_position_hook): Likewise.
20731 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20732 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20733 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20734 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20735 what it was before.
20736 * menu.h, termhooks.h: Include "systime.h", for Time.
20738 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20739 Don't assume that the difference between two unsigned long values
20740 can fit into an integer. At this point, we know button_down_time
20741 <= event->timestamp, so the difference must be nonnegative, so
20742 there's no need to cast the result if double-click-time is
20743 nonnegative, as it should be; check that it's nonnegative, just in
20744 case. This bug is triggered when events are more than 2**31 ms
20745 apart (about 25 days). (Bug#8664)
20747 * xselect.c (last_event_timestamp): Remove duplicate decl.
20748 (x_own_selection): Remove needless cast to unsigned long.
20750 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20751 that always fit in int. Use a sentinel instead of a counter, to
20752 avoid a temp and to allay GCC's concerns about possible int overflow.
20753 * frame.h (struct frame): Use int for menu_bar_items_used
20754 instead of EMACS_INT, since it always fits in int.
20756 * menu.c (grow_menu_items): Check for int overflow.
20758 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20760 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20761 Before, the code was not consistent. These values cannot exceed
20762 2**31 - 1 so there's no need to make them unsigned.
20763 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20764 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20765 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20767 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20769 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20770 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20771 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20772 presumably because the widths might not match.
20774 * window.c (size_window): Avoid needless test at loop start.
20776 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20778 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20780 2011-05-12 Drew Adams <drew.adams@oracle.com>
20782 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20784 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20786 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20787 `width' to `bar_area_x' and `bar_area_width', respectively.
20788 (x_scroll_run): Take account of fringe background extension.
20790 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20791 Rename local vars `left' and `width' to `bar_area_x' and
20792 `bar_area_width', respectively.
20793 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20794 background extension.
20796 2011-05-10 Jim Meyering <meyering@redhat.com>
20798 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20800 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20802 * image.c (Finit_image_library): Return t for built-in image types,
20803 like pbm and xbm. (Bug#8640)
20805 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20807 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20809 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20811 * w32console.c (Fset_screen_color): Doc fix.
20812 (Fget_screen_color): New function.
20813 (syms_of_ntterm): Defsubr it.
20815 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20816 unlink the temporary file if Fcall_process didn't create it in the
20818 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20819 child process will be redirected to a file specified with `:file'.
20820 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20821 cue to call_process_cleanup not to close that handle.
20823 2011-05-07 Ben Key <bkey76@gmail.com>
20825 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20826 one of two shell specific rules, either bootstrap-temacs-CMD or
20827 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20828 to the previous implementation of the bootstrap-temacs rule.
20829 The bootstrap-temacs-CMD rule is similar to the previous
20830 implementation of the bootstrap-temacs rule except that it
20831 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20834 These changes, along with some changes to nt/configure.bat,
20835 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20836 earlier fix to add support for --cflags and --ldflags options
20837 that include quotes so that it works whether make uses cmd or
20840 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20842 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20843 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20845 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20846 a string. Handle both cases.
20847 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20848 (Fdbus_register_method): Use Qinvalid_function.
20850 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20852 * makefile.w32-in: Update dependencies.
20853 (LISP_H): Add inttypes.h and stdin.h.
20854 (PROCESS_H): Add unistd.h.
20856 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20858 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20859 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20861 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20863 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20865 * term.c (vfatal): Remove stray call to va_end.
20866 It's not needed and the C Standard doesn't allow it here anyway.
20868 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20869 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20871 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20874 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20876 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20878 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20880 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20882 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20884 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20885 * charset.c (Fdefine_charset_internal): Don't initialize
20886 charset.code_space[15]. The value was garbage, on hosts with
20887 32-bit int (Bug#8600).
20889 * lread.c (read_integer): Be more consistent with string-to-number.
20890 Use string_to_number to do the actual conversion; this avoids
20891 rounding errors and fixes some other screwups. Without this fix,
20892 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20893 (digit_to_number): Move earlier, for benefit of read_integer.
20894 Return -1 if the digit is out of range for the base, -2 if it is
20895 not a digit in any supported base. (Bug#8602)
20897 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20899 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20900 to match comment at start of function. This also removes a
20901 GCC warning about overflow in a 32+64-bit port.
20903 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20905 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20906 Reported by Stefan Monnier in
20907 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20908 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20909 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20911 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20912 (EMACS_UINTPTR): Likewise, with uintptr_t.
20914 * lisp.h: Prefer 64-bit EMACS_INT if available.
20915 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20916 on 32-bit hosts that have 64-bit int, so that they can access
20918 However, temporarily disable this change unless the temporary
20919 symbol WIDE_EMACS_INT is defined.
20921 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20923 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20924 This removes an assumption that EMACS_INT and long are the same
20925 width as pointers. The assumption is true for Emacs porting targets
20926 now, but we want to make other targets possible.
20927 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20928 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20929 In the rest of the code, change types of integers that hold casted
20930 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20931 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20932 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20933 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20934 No need to cast type when ORing.
20935 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20936 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20937 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20938 assume EMACS_INT is the same width as char *.
20939 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20940 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20941 Remove no-longer-needed casts.
20942 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20943 (xg_tool_bar_help_callback, xg_make_tool_item):
20944 Use EMACS_INTPTR to hold an integer
20945 that will be cast to void *; this can avoid a GCC warning
20946 if EMACS_INT is not the same width as void *.
20947 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20948 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20949 (current_message_1, set_message_1):
20950 Use a local to convert to proper width without a cast.
20951 * xmenu.c (dialog_selection_callback): Likewise.
20953 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20954 Also, don't assume VALBITS / RAND_BITS is less than 5,
20955 and don't rely on undefined behavior when shifting a 1 left into
20957 * lisp.h (get_random): Change signature to match.
20959 * lread.c (hash_string): Use size_t, not int, for hash computation.
20960 Normally we prefer signed values; but hashing is special, because
20961 it's better to use unsigned division on hash table sizes so that
20962 the remainder is nonnegative. Also, size_t is the natural width
20963 for hashing into memory. The previous code used 'int', which doesn't
20964 retain enough info to hash well into very large tables.
20965 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20967 * dbusbind.c: Don't possibly lose pointer info when converting.
20968 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20969 Use XPNTR rather than XHASH, so that the high-order bits of
20970 the pointer aren't lost when converting through void *.
20972 * eval.c (Fautoload): Don't double-shift a pointer.
20974 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20976 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20978 * gnutls.c (DEF_GNUTLS_FN):
20979 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20981 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20983 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20986 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20988 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20989 New version that can reserve upto 2GB of heap space.
20991 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20993 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20995 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20997 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20998 `gnutls_certificate_set_x509_key_file'.
21000 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
21002 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
21003 Update dependencies.
21005 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21007 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
21008 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
21009 Remove unused parameter `fildes'.
21010 * process.c (read_process_output, send_process): Don't pass it.
21012 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21014 Fix previous change: the library cache is defined in w32.c.
21015 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
21016 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
21018 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
21020 Implement dynamic loading of GnuTLS on Windows.
21022 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
21023 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
21024 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21027 * gnutls.c (Qgnutls_dll): Define.
21028 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
21029 (gnutls_*): Declare function pointers.
21030 (init_gnutls_functions): New function to initialize function pointers.

21032 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
21033 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
21034 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
21035 (emacs_gnutls_write, emacs_gnutls_read)
21036 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
21037 (Fgnutls_available_p): New function.
21038 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
21039 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
21040 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
21042 * image.c: Include w32.h.
21043 (Vimage_type_cache): Delete.

21048 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
21050 * w32.c (QCloaded_from, Vlibrary_cache): Define.
21051 (w32_delayed_load): Move from image.c. When loading a library, record
21052 its filename in the :loaded-from property of the library id.
21053 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
21054 Initialize and staticpro them.
21055 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
21057 * process.c: Include lisp.h before w32.h, not after.
21058 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
21059 instead of gnutls_record_check_pending.
21061 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
21063 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
21065 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
21066 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
21069 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
21071 * xterm.c (x_set_frame_alpha): Do not set property on anything
21072 else than FRAME_X_OUTER_WINDOW (Bug#8608).
21074 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21076 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21078 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21080 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
21081 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

21090 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
21092 * callproc.c: Indentation fixup.
21094 * sysdep.c (wait_for_termination_1): Make static.
21095 (wait_for_termination, interruptible_wait_for_termination):
21096 Move after wait_for_termination_1.
21098 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21100 * sysdep.c (interruptible_wait_for_termination): New function
21101 which is like wait_for_termination, but allows keyboard
21104 * callproc.c (Fcall_process): Add (:file "file") as an option for
21106 (Fcall_process_region): Ditto.
21108 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21110 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21111 rather than `XVECTOR (FOO)->size'.
21113 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21114 inttypes.h, as a gnulib replacement is used if it not available in
21117 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21119 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21120 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21121 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21123 * coding.c (coding_alloc_by_realloc): Error out if destination
21124 will grow beyond MOST_POSITIVE_FIXNUM.
21125 (decode_coding_emacs_mule): Abort if there isn't enough place in
21126 charbuf for the composition carryover bytes. Reserve an extra
21127 space for up to 2 characters produced in a loop.
21128 (decode_coding_iso_2022): Abort if there isn't enough place in
21129 charbuf for the composition carryover bytes.
21131 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21133 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
21134 aborting when %lld or %lll format is passed.
21135 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21136 %llo or %llx format is passed. (Bug#8545)
21138 * window.c (window_scroll_line_based): Use a marker instead of
21139 simple variables to record original value of point. (Bug#7952)
21141 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21142 produced by %s or %c overflows available buffer space. (Bug#8545)
21144 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21146 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21147 (SIZE_MAX): Move defn after all includes, as they might #define it.
21149 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21151 * w32.c (init_environment): Warn about defaulting HOME to C:\.
21153 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21155 * keyboard.c (Qdelayed_warnings_hook): Define.
21156 (command_loop_1): Run `delayed-warnings-hook'
21157 if Vdelayed_warnings_list is non-nil.
21158 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21159 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21161 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21163 * doprnt.c (doprnt): Don't return value smaller than the buffer
21164 size if the message was truncated. (Bug#8545).
21166 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21168 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21169 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21171 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21173 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21175 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21177 * makefile.w32-in: Update dependencies.
21179 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21181 Improve `doprnt' and its usage. (Bug#8545)
21182 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21183 `format_end'. Remove support for %l as a conversion specifier.
21184 Don't use xrealloc. Improve diagnostics when the %l size modifier
21185 is used. Update the commentary.
21187 * eval.c (verror): Simplify calculation of size_t.
21189 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21192 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21194 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21197 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21199 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21200 This makes this file independent of the recent pseudovector change.
21202 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21204 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21206 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21207 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21208 Remove unused local.
21209 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21211 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21212 GCC 4.6.0 optimizes based on type-based alias analysis.
21213 For example, if b is of type struct buffer * and v of type struct
21214 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21215 != &v->size, and therefore "v->size = 1; b->size = 2; return
21216 v->size;" must therefore return 1. This assumption is incorrect
21217 for Emacs, since it type-puns struct Lisp_Vector * with many other
21218 types. To fix this problem, this patch adds a new type struct
21219 vectorlike_header that documents the constraints on layout of vectors
21220 and pseudovectors, and helps optimizing compilers not get fooled
21221 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21222 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21223 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21225 (XSETPVECTYPE): Rewrite in terms of new macro.
21226 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21227 This is a bit clearer, and further avoids the possibility of
21228 undesirable aliasing.
21229 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21230 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21231 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21232 since Lisp_Subr is a special case (no "next" field).
21233 (ASIZE): Now uses header.size rather than size.
21234 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21235 to avoid the hassle of writing XVECTOR (foo)->header.size.
21236 (struct vectorlike_header): New type.
21237 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21238 object, to help avoid aliasing.
21239 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21240 (SUBRP): Likewise, since Lisp_Subr is a special case.
21241 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21242 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21243 (struct Lisp_Hash_Table): Combine first two members into a single
21244 struct vectorlike_header member. All uses of "size" and "next" members
21245 changed to be "header.size" and "header.next".
21246 * buffer.h (struct buffer): Likewise.
21247 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21248 * frame.h (struct frame): Likewise.
21249 * process.h (struct Lisp_Process): Likewise.
21250 * termhooks.h (struct terminal): Likewise.
21251 * window.c (struct save_window_data, struct saved_window): Likewise.
21252 * window.h (struct window): Likewise.
21253 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21254 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21255 * buffer.c (init_buffer_once): Likewise.
21256 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21258 * process.c (Fformat_network_address): Use local var for size,
21261 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21263 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21264 * data.c (atof): Remove decl; no longer used or needed.
21265 (digit_to_number): Move to lread.c.
21266 (Fstring_to_number): Use new string_to_number function, to be
21267 consistent with how the Lisp reader treats infinities and NaNs.
21268 Do not assume that floating-point numbers represent EMACS_INT
21269 without losing information; this is not true on most 64-bit hosts.
21270 Avoid double-rounding errors, by insisting on integers when
21271 parsing non-base-10 numbers, as the documentation specifies.
21272 * lisp.h (string_to_number): New decl, replacing ...
21273 (isfloat_string): Remove.
21274 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21275 (read1): Do not accept +. and -. as integers; this
21276 appears to have been a coding error. Similarly, do not accept
21277 strings like +-1e0 as floating point numbers. Do not report
21278 overflow for integer overflows unless the base is not 10 which
21279 means we have no simple and reliable way to continue.
21280 Break out the floating-point parsing into a new
21281 function string_to_number, so that Fstring_to_number parses
21282 floating point numbers consistently with the Lisp reader.
21283 (digit_to_number): Move here from data.c. Make it static inline.
21284 (E_CHAR, EXP_INT): Remove, replacing with ...
21285 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21286 (string_to_number): New function, replacing isfloat_string.
21287 This function checks for valid syntax and produces the resulting
21288 Lisp float number too. Rework it so that string-to-number
21289 no longer mishandles examples like "1.0e+". Use strtoumax,
21290 so that overflow for non-base-10 numbers is reported only when
21291 there's no portable and simple way to convert to floating point.
21293 * textprop.c (set_text_properties_1): Rewrite for clarity,
21294 and to avoid GCC warning about integer overflow.
21296 * intervals.h (struct interval): Use EMACS_INT for members
21297 where EMACS_UINT might cause problems. See
21298 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21299 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21300 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21302 (offset_intervals): Tell GCC not to worry about length overflow
21303 when negating a negative length.
21305 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21306 (overrun_check_free): Likewise.
21308 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21309 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21312 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21313 (gnutls_make_error): Rename local to avoid shadowing.
21314 (gnutls_emacs_global_deinit): ifdef out; not used.
21315 (Fgnutls_boot): Use const for pointer to readonly storage.
21316 Comment out unused local. Fix pointer signedness problems.
21318 * lread.c (openp): Don't stuff size_t into an 'int'.
21319 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21320 about possible signed overflow.
21322 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21323 (GDK_KEY_g): Don't define if already defined.
21324 (xg_prepare_tooltip): Avoid pointer signedness problem.
21325 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21327 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21328 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21330 * xfns.c (Fx_window_property): Simplify a bit,
21331 to make a bit faster and to avoid GCC 4.6.0 warning.
21332 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21334 * fns.c (internal_equal): Don't assume size_t fits in int.
21336 * alloc.c (compact_small_strings): Tighten assertion a little.
21338 Replace pEd with more-general pI, and fix some printf arg casts.
21339 * lisp.h (pI): New macro, generalizing old pEd macro to other
21340 conversion specifiers. For example, use "...%"pI"d..." rather
21341 than "...%"pEd"...".
21342 (pEd): Remove. All uses replaced with similar uses of pI.
21343 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21344 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21345 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21346 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21347 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21348 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21349 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21351 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21352 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21353 * print.c (safe_debug_print, print_object): Likewise.
21354 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21356 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21357 avoiding the 0 flag, which is not portable.
21358 * process.c (Fmake_network_process): Use pI to avoid cast.
21359 * region-cache.c (pp_cache): Likewise.
21360 * xdisp.c (decode_mode_spec): Likewise.
21361 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21362 behavior on 64-bit hosts with printf arg.
21363 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21364 (x_stop_queuing_selection_requests): Likewise.
21365 (x_get_window_property): Don't truncate byte count to an 'int'
21368 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21369 here, since it parses constructs like leading '-' and spaces,
21370 which are not wanted; and it overflows with large numbers.
21371 Instead, simply match F[0-9]+, which is what is wanted anyway.
21373 * alloc.c: Remove unportable assumptions about struct layout.
21374 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21375 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21376 (allocate_vectorlike, make_pure_vector): Use the new macros,
21377 plus offsetof, to remove unportable assumptions about struct layout.
21378 These assumptions hold on all porting targets that I know of, but
21379 they are not guaranteed, they're easy to remove, and removing them
21380 makes further changes easier.
21382 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21383 This doesn't fix a bug but makes the code clearer.
21384 (string_overrun_cookie): Now const. Use initializers that
21385 don't formally overflow signed char, to avoid warnings.
21386 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21387 can cause Emacs to crash when string overrun checking is enabled.
21388 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21389 multiple of sizeof (EMACS_INT); it need not be, if
21390 alignof(EMACS_INT) < sizeof (EMACS_INT).
21391 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21393 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21400 supposed to be handshaking. (Bug#8556)
21401 Reported by Paul Eggert <eggert@cs.ucla.edu>.
21403 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

21420 2011-04-25 Eli Zaretskii <eliz@gnu.org>
21422 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21423 "cast to pointer from integer of different size".
21425 Improve doprnt and its use in verror. (Bug#8545)
21426 * doprnt.c (doprnt): Document the set of format control sequences
21427 supported by the function. Use SAFE_ALLOCA instead of always
21430 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21431 is one byte too soon. Don't use xrealloc; instead xfree and
21434 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21436 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
21439 * gnutls.c: Renamed global_initialized to
21440 gnutls_global_initialized. Added internals for the
21441 :verify-hostname-error, :verify-error, and :verify-flags
21442 parameters of `gnutls-boot' and documented those parameters in the
21443 docstring. Start callback support.
21444 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21445 unless a fatal error occurred. Call gnutls_alert_send_appropriate

21519 (SIZE_MAX): New macro.
21520 (doprnt): Return a size_t value. 2nd arg is now size_t.
21521 Many local variables are now size_t instead of int or unsigned.
21522 Improve overflow protection. Support `l' modifier for integer
21523 conversions. Support %l conversion. Don't assume an EMACS_INT
21524 argument for integer conversions and for %c.
21526 * lisp.h (doprnt): Restore prototype.
21528 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
21529 $(SRC)/character.h.
21531 * Makefile.in (base_obj): Add back doprnt.o.
21533 * deps.mk (doprnt.o): Add back prerequisites.

21543 * callint.c (Fcall_interactively): When displaying error message
21544 about invalid control letter, pass the character's codepoint, not
21545 a pointer to its multibyte form. Improve display of the character
21546 in octal and display also its hex code.
21548 * character.c (char_string): Use %x to display the (unsigned)
21549 codepoint of an invalid character, to avoid displaying a bogus
21552 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21553 `error', not SYMBOL_NAME itself.
21555 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
21556 character arguments to `error'.
21558 * charset.c (check_iso_charset_parameter): Fix incorrect argument

21631 * dispextern.h (struct redisplay_interface): Rename param
21632 to avoid shadowing.
21633 * termhooks.h (struct terminal): Likewise.

21637 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
21639 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
21642 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
21643 so that we aren't warned about unused symbols.

21660 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
21662 * xmenu.c (menu_help_callback): Pointer type fixes.

21680 compatible char. Avoid the old compiler warnings about
21681 out-of-range initializers by using, for example, '\xab' rather
21684 * xgselect.c (xgselect_initialize): Check vs interface
21685 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

21750 * nsfont.m: Fixed bugs in ns_get_family and
21751 ns_descriptor_to_entity that were caused by using free to
21752 deallocate memory blocks that were allocated by xmalloc (via
21753 xstrdup). This caused Emacs to crash when compiled with
21754 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21755 --enable-checking=xmallocoverrun). xfree is now used to
21756 deallocate these memory blocks.

22165 DEFUN now defines a static function. To make the function external
22166 so that it can be used in other C modules, use the new macro DEFUE.
22167 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
22168 (Finit_image_library):
22169 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
22170 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
22171 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
22172 Remove decls, since these functions are now static.
22173 (Funintern, Fget_internal_run_time): New decls, since these functions
22174 were already external.
22176 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
22177 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
22178 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:

22180 * keyboard.c, keymap.c, lread.c:
22181 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
22182 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
22183 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
22184 Mark functions with DEFUE instead of DEFUN,
22185 if they are used in other modules.
22186 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
22187 decls for now-static functions.
22188 * buffer.h (Fdelete_overlay): Remove decl.
22189 * callproc.c (Fgetenv_internal): Mark as internal.
22190 * composite.c (Fremove_list_of_text_properties): Remove decl.

22196 (Funintern): Remove extern decl; now in .h file where it belongs.
22197 * fileio.c (Fmake_symbolic_link): New forward static decl.
22198 * image.c (Finit_image_library): New forward static decl.
22199 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
22200 * intervals.h (Fprevious_property_change):
22201 (Fremove_list_of_text_properties): Remove decls.

22224 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22226 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22227 when at ZV. (Bug#8487)
22229 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22231 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22233 * keyboard.c (parse_tool_bar_item): Likewise.
22234 * sound.c (sound_cleanup, alsa_close): Likewise.
22235 * termcap.c (tgetent): Likewise.
22236 * xfns.c (x_default_font_parameter): Likewise.
22237 * xsettings.c (read_and_apply_settings): Likewise.
22239 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22240 (overrun_check_free): Protoize.
22242 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22244 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22245 since callers should never pass a negative size.
22246 Change the signature to match that of plain 'read' and 'write'; see
22247 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22248 * lisp.h: Update prototypes of emacs_write and emacs_read.
22250 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22252 * xdisp.c (redisplay_window): Don't try to determine the character
22253 position of the scroll margin if the window start point w->startp
22254 is outside the buffer's accessible region. (Bug#8468)
22256 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22258 Fix write-region and its subroutines for buffers > 2GB.
22259 * fileio.c (a_write, e_write): Modify declaration of arguments and
22260 local variables to support buffers larger than 2GB.
22261 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22263 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22264 argument, local variables, and return value.
22266 * lisp.h: Update prototypes of emacs_write and emacs_read.
22268 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22270 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22272 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22274 Fix more problems found by GCC 4.6.0's static checks.
22276 * xdisp.c (vmessage): Use a better test for character truncation.
22278 * charset.c (load_charset_map): <, not <=, for optimization,
22279 and to avoid potential problems with integer overflow.
22280 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22281 * casetab.c (set_identity, shuffle): Likewise.
22282 * editfns.c (Fformat): Likewise.
22283 * syntax.c (skip_chars): Likewise.
22285 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22286 This also lets GCC 4.6.0 generate slightly better loop code.
22288 * callint.c (Fcall_interactively): <, not <=, for optimization.
22289 (Fcall_interactively): Count the number of arguments produced,
22290 not the number of arguments given. This is simpler and lets GCC
22291 4.6.0 generate slightly better code.
22293 * ftfont.c: Distingish more carefully between FcChar8 and char.
22294 The previous code passed unsigned char * to a functions like
22295 strlen and xstrcasecmp that expect char *, which does not
22296 conform to the C standard.
22297 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22298 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22299 char * when the C standard requires it.
22301 * keyboard.c (read_char): Remove unused var.
22303 * eval.c: Port to Windows vsnprintf (Bug#8435).
22304 Include <limits.h>.
22305 (SIZE_MAX): Define if the headers do not.
22306 (verror): Do not give up if vsnprintf returns a negative count.
22307 Instead, grow the buffer. This ports to Windows vsnprintf, which
22308 does not conform to C99. Problem reported by Eli Zaretskii.
22309 Also, simplify the allocation scheme, by avoiding the need for
22310 calling realloc, and removing the ALLOCATED variable.
22312 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22314 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22315 But keep the doprint source code for now, as we might revamp it
22316 and use it again (Bug#8435).
22317 * lisp.h (doprnt): Remove.
22318 * Makefile.in (base_obj): Remove doprnt.o.
22319 * deps.mk (doprnt.o): Remove.
22321 error: Print 32- and 64-bit integers portably (Bug#8435).
22322 Without this change, on typical 64-bit hosts error ("...%d...", N)
22323 was used to print both 32- and 64-bit integers N, which relied on
22324 undefined behavior.
22325 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22326 * lisp.h (error, verror): Mark as printf-like functions.
22327 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22328 Report overflow in size calculations when allocating printf buffer.
22329 Do not truncate output string at its first null byte.
22330 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22331 Truncate the output at a character boundary, since vsnprintf does not
22333 * charset.c (check_iso_charset_parameter): Convert internal
22334 character to string before calling 'error', since %c now has the
22336 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22337 overflow when computing char to be passed to 'error'. Do not
22338 pass Lisp_Object to 'error'; pass the integer instead.
22339 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22340 formatted with plain %d.
22342 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22344 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22346 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22348 * xterm.c (x_catch_errors): Remove duplicate declaration.
22350 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22352 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22354 2011-04-10 Jim Meyering <meyering@redhat.com>
22356 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22357 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22358 return ssize_t not "int", and use size_t as the buffer length.
22359 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22360 * gnutls.h: Update declarations.
22361 * process.c (read_process_output): Use ssize_t, to match.
22362 (send_process): Likewise.
22364 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22366 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22368 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22370 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22371 Use unsigned char, to match FcChar8 type definition.
22373 * xterm.c (handle_one_xevent):
22374 * xmenu.c (create_and_show_popup_menu):
22375 * xselect.c (x_decline_selection_request)
22376 (x_reply_selection_request): Avoid type-punned deref of X events.
22378 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22380 Fix some uses of `int' instead of EMACS_INT.
22381 * search.c (string_match_1, fast_string_match)
22382 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22383 (scan_buffer, find_next_newline_no_quit)
22384 (find_before_next_newline, search_command, Freplace_match)
22385 (Fmatch_data): Make some `int' variables be EMACS_INT.
22387 * xdisp.c (display_count_lines): 3rd argument and return value now
22388 EMACS_INT. All callers changed.
22389 (pint2hrstr): Last argument is now EMACS_INT.
22391 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22392 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22393 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22394 (decode_coding_utf_16, decode_coding_emacs_mule)

22396 (decode_coding_ccl, decode_coding_charset)
22397 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22398 (decode_coding_iso_2022, decode_coding_emacs_mule)
22399 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)

22404 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22405 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22407 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22408 (encode_invocation_designation): Last argument P_NCHARS is now
22410 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22411 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22413 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22416 * ccl.c (Fccl_execute_on_string): Declare some variables
22419 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22421 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22423 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22425 * process.c (Fformat_network_address): Doc fix.
22427 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22429 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22431 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22433 * keyboard.c (read_char): Call Lisp function help-form-show,
22434 instead of using internal_with_output_to_temp_buffer.
22435 (Qhelp_form_show): New var.
22436 (syms_of_keyboard): Use DEFSYM macro.
22438 * print.c (internal_with_output_to_temp_buffer): Function deleted.
22440 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
22442 2011-04-06 Chong Yidong <cyd@stupidchicken.com>

22449 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22451 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22453 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22455 Fix more problems found by GCC 4.6.0's static checks.

22461 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22463 * xdisp.c (vmessage): Mark as a printf-like function.
22465 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

22472 to system-supplied API.
22474 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22476 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22477 This avoids several warnings with gcc -Wstrict-overflow.
22478 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22479 directly, rather than having caller test rule sign. This avoids
22480 some unnecessary tests.
22481 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22482 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22483 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22485 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22486 (xfont_open): Avoid unnecessary tests.
22488 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22490 * composite.h, composite.c (composition_gstring_put_cache):
22491 Use EMACS_INT, not int, for length.

22497 by using the new macro.
22499 * textprop.c (set_text_properties_1): Change while to do-while,
22500 since the condition is always true at first.
22502 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22503 (interval_deletion_adjustment): Return unsigned value.
22506 * process.c (list_processes_1, create_pty, read_process_output):

22516 (update_syntax_table): Use unsigned instead of int.
22518 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22519 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22520 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22522 * print.c (print_error_message): Avoid int overflow.
22524 * font.c (font_list_entities): Redo for clarity,
22525 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22527 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22528 (font_score): Avoid potential overflow in diff calculation.
22530 * fns.c (substring_both): Remove var that is set but not used.
22531 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22533 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22535 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22536 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22537 can always succeed if overflow has undefined behavior.
22539 * search.c (boyer_moore, wordify): Remove vars set but not used.
22540 (wordify): Omit three unnecessary tests.
22542 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22543 All callers changed. This avoids the need for an unused var.
22545 * casefiddle.c (casify_region): Remove var that is set but not used.
22547 * dired.c (file_name_completion): Remove var that is set but not used.
22549 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22551 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22552 (Finsert_file_contents): Remove unnecessary code checking fd.
22554 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22555 Check for integer overflow on size calculations.
22557 * buffer.c (Fprevious_overlay_change): Remove var that is set
22560 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22561 Remove vars that are set but not used.
22562 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22563 (timer_check_2): Mark vars as initialized.
22565 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22567 * image.c (lookup_image): Remove var that is set but not used.
22568 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22570 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22571 that are set but not used.
22573 * xfns.c (make_invisible_cursor): Don't return garbage
22574 if XCreateBitmapFromData fails (Bug#8410).
22576 * xselect.c (x_get_local_selection, x_handle_property_notify):
22577 Remove vars that are set but not used.
22579 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22580 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22582 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22583 Remove var that is set but not used.
22584 (scroll_bar_windows_size): Now size_t, not int.
22585 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22586 Check for overflow.
22588 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22589 (map_tty_color) [!defined MSDOS]: Likewise.
22591 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22593 * coding.c: Remove vars that are set but not used.
22594 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22595 All callers changed.
22596 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22597 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22598 (decode_coding_charset): Remove vars that are set but not used.
22600 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22601 that is set but not used.
22603 * print.c (print_object): Remove var that is set but not used.
22605 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22606 The gnulib version avoids calling malloc in the usual case,
22607 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22608 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22609 * filelock.c (current_lock_owner): Likewise.

22612 (emacs_no_realloc_allocator): New static constant.
22613 (emacs_readlink): New function.
22614 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on

22642 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22643 (ns_get_family): Likewise.

22651 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22654 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22656 Add lexical binding.

22667 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22669 (syms_of_lread): Declare `lexical-binding'.
22671 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22673 * keyboard.c (eval_dyn): New fun.
22674 (menu_item_eval_property): Use it.

22682 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22683 (FletX, Flet): Obey lexical binding.
22684 (Fcommandp): Handle closures.
22685 (Feval): New `lexical' arg.
22686 (eval_sub): New function extracted from Feval. Use it almost
22687 everywhere where Feval was used. Look up vars in lexical env.
22689 (Ffunctionp): Move from subr.el.
22690 (Ffuncall): Handle closures.
22691 (apply_lambda): Remove `eval_flags'.
22692 (funcall_lambda): Handle closures and new byte-code-functions.
22693 (Fspecial_variable_p): New function.
22694 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22695 but without exporting it to Lisp.
22697 * doc.c (Fdocumentation, store_function_docstring):
22698 * data.c (Finteractive_form): Handle closures.
22700 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22703 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22705 (exec_byte_code): New function extracted from Fbyte_code to handle new
22706 calling convention for byte-code-functions. Add new byte-codes.
22708 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

22720 Limit scrolling to 100 screen lines.
22721 (redisplay_window): Even when falling back on "recentering",
22722 position point in the window according to scroll-conservatively,
22723 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22725 (try_scrolling): When point is above the window, allow searching
22726 as far as scroll_max, or one screenful, to compute vertical
22727 distance from PT to the scroll margin position. This prevents
22728 try_scrolling from unnecessarily failing when
22729 scroll-conservatively is set to a value slightly larger than the
22730 window height. Clean up the case of PT below the margin at bottom
22731 of window: scroll_max can no longer be INT_MAX. When aggressive
22732 scrolling is in use, don't let point enter the opposite scroll
22733 margin as result of the scroll.
22734 (syms_of_xdisp) <scroll-conservatively>: Document the
22735 threshold of 100 lines for never-recentering scrolling.

22745 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22747 * indent.c (Fvertical_motion):
22748 * window.c (window_scroll_pixel_based, Frecenter):
22749 Don't pass `need_y_p' to `move_it_by_lines'.

22753 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22754 steal a few bits to be more compact.
22755 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22756 Remove unneeded casts.
22758 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22760 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22762 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22763 binding" message (bug#7967).
22765 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22767 Fix more problems found by GCC 4.6.0's static checks.
22769 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22770 Remove unused local var.
22772 * editfns.c (Fmessage_box): Remove unused local var.
22774 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22775 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22776 Omit unused local vars.
22777 * window.c (shrink_windows): Omit unused local var.
22778 * menu.c (digest_single_submenu): Omit unused local var.
22779 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22780 Omit unused local var.
22782 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22783 Don't assume string length fits in int.
22784 (keyremap_step, read_key_sequence): Use size_t for sizes.

22788 instead of alloca (Bug#8344).
22790 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22791 (Fbacktrace_frame): Don't assume nframes fits in int.

22800 * cm.c (calccost): Turn while-do into do-while, for clarity.
22802 * keyboard.c (syms_of_keyboard): Use the same style as later
22803 in this function when indexing through an array. This also
22804 works around GCC bug 48267.
22806 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22808 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22810 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22811 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22813 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22814 This avoids undefined behavior on integer overflow, and is a bit
22815 more convenient anyway since it is compared to a size_t variable.
22817 Variadic C functions now count arguments with size_t, not int.
22818 This avoids an unnecessary limitation on 64-bit machines, which
22819 caused (substring ...) to crash on large vectors (Bug#8344).

22829 * fns.c (concat): Likewise.
22830 * frame.c (x_set_frame_parameters): Likewise.
22831 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22832 0 if not found, not -1. All callers changed.
22834 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22835 (stack_copy_size): Now size_t, not int.
22836 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22838 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

22857 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22858 don't set the hook to nil, but remove the offending function instead.

22861 Vcommand_hook_internal.

22864 (funcall_nil, funcall_not): New functions.
22865 (run_hook_with_args): Call each function through a `funcall' argument.

23044 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
23045 unconditionally since it does the check itself.
23047 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
23049 Fix more problems found by GCC 4.5.2's static checks.
23051 * coding.c (encode_coding_raw_text): Avoid unnecessary test
23052 the first time through the loop, since we know p0 < p1 then.
23053 This also avoids a gcc -Wstrict-overflow warning.
23055 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
23056 leading to a memory leak, possible in functions like
23057 load_charset_map_from_file that can allocate an unbounded number
23058 of objects (Bug#8318).
23060 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
23061 that could (at least in theory) be that large.
23063 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
23064 This is less likely to overflow, and avoids undefined behavior if
23065 overflow does occur. All callers changed. Use strtoul to scan
23066 for the unsigned long integer.
23067 (pint2hrstr): Simplify and tune code slightly.
23068 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
23070 * scroll.c (do_scrolling): Work around GCC bug 48228.
23071 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
23073 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
23074 This also avoids a warning with gcc -Wstrict-overflow.
23075 (validate_x_resource_name): Simplify count usage.
23076 This also avoids a warning with gcc -Wstrict-overflow.
23078 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23081 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23083 * process.c (Fmake_network_process): Use socklen_t, not int,
23084 where POSIX says socklen_t is required in portable programs.
23085 This fixes a porting bug on hosts like 64-bit HP-UX, where
23086 socklen_t is wider than int (Bug#8277).
23087 (Fmake_network_process, server_accept_connection):
23088 (wait_reading_process_output, read_process_output):
23091 * process.c: Rename or move locals to avoid shadowing.

23101 Make tparam.h and terminfo.c consistent.
23102 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23103 Include tparam.h instead, since it declares them.
23104 * cm.h (PC): Remove extern decl; tparam.h now does this.
23105 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23106 * terminfo.c: Include tparam.h, to check interfaces.
23107 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23108 (tparam): Adjust signature to match interface in tparam.h;
23109 this removes some undefined behavior. Check that outstring and len
23110 are zero, which they always are with Emacs.
23111 * tparam.h (PC, BC, UP): New extern decls.
23113 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
23114 (xftfont_open): Rename locals to avoid shadowing.
23116 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

23126 * xml.c (make_dom): Now static.
23128 * composite.c (composition_compute_stop_pos): Rename local to
23130 (composition_reseat_it): Remove unused locals.
23131 (find_automatic_composition, composition_adjust_point): Likewise.
23132 (composition_update_it): Mark var as initialized.
23133 (find_automatic_composition): Mark vars as initialized,
23134 with a FIXME (Bug#8290).

23138 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
23139 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
23140 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23141 to avoid shadowing.
23143 * textprop.c (property_change_between_p): Remove; unused.
23145 * intervals.c (interval_start_pos): Now static.
23147 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

23150 Rename locals to avoid shadowing.
23152 * sound.c (wav_play, au_play, Fplay_sound_internal):
23153 Fix pointer signedness.
23154 (alsa_choose_format): Remove unused local var.
23155 (wav_play): Initialize a variable to 0, to prevent undefined
23156 behavior (Bug#8278).
23158 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23160 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23162 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23163 clobbering (Bug#8298).
23164 * sysdep.c (sys_subshell): Likewise.
23165 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23167 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23168 This should get cleaned up, so that child_setup has the
23169 same signature on all platforms.
23171 * callproc.c (call_process_cleanup): Now static.
23172 (relocate_fd): Rename locals to avoid shadowing.
23174 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
23176 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
23177 not to be necessary, and produces flickering.
23179 2011-03-20 Glenn Morris <rgm@gnu.org>
23181 * config.in: Remove file.
23183 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
23185 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
23186 are now in src/globals.h.
23187 (syms_of_minibuf): Remove spurious & from previous change.
23189 2011-03-20 Leo Liu <sdl.web@gmail.com>
23191 * minibuf.c (completing-read-function): New variable.
23192 (completing-read-default): Rename from completing-read.
23193 (completing-read): Call completing-read-function.
23195 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23197 * xfaces.c (Fx_load_color_file):
23198 Read color file from absolute filename (bug#8250).
23200 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
23202 * makefile.w32-in: Update dependencies.
23204 2011-03-17 Eli Zaretskii <eliz@gnu.org>
23206 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

23213 (sigchld_handler): Now static.
23215 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
23216 That way, the code declares only the vars that it needs.
23217 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
23218 * s/cygwin.h (PTY_ITERATION): Likewise.
23219 * s/darwin.h (PTY_ITERATION): Likewise.

23226 (CONSTANTLIM): Remove; unused.
23227 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
23228 Define only if needed.
23230 * unexelf.c (unexec): Name an expression,
23231 to avoid gcc -Wbad-function-cast warning.
23232 Use a different way to cause a compilation error if anyone uses
23233 n rather than nn, a way that does not involve shadowing.
23234 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
23236 * deps.mk (unexalpha.o): Remove; unused.
23238 New file unexec.h, the (simple) interface for unexec (Bug#8267).
23239 * unexec.h: New file.
23240 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
23241 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
23242 Depend on unexec.h.
23243 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
23244 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
23245 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
23246 Change as necessary to match prototype in unexec.h.
23248 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
23250 (back_comment, skip_chars): Mark vars as initialized.

23265 (font_sort_entities): Mark var as initialized.
23267 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
23269 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

23293 * callint.c (quotify_arg, quotify_args): Now static.
23294 (Fcall_interactively): Rename locals to avoid shadowing.
23295 Use const pointer when appropriate.

23301 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
23302 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
23303 some of which prompt warnings from gcc -Wbad-function-cast.
23304 (Fformat_time_string, Fencode_time, Finsert_char):
23305 (Ftranslate_region_internal, Fformat):
23306 Rename or remove local vars to avoid shadowing.
23307 (Ftranslate_region_internal): Mark var as initialized.
23309 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
23312 * lisp.h (eassert): Check that the argument compiles, even if
23313 ENABLE_CHECKING is not defined.
23315 * data.c (Findirect_variable): Name an expression, to avoid
23316 gcc -Wbad-function-cast warning.
23317 (default_value, arithcompare, arith_driver, arith_error): Now static.

23325 Rename locals to avoid shadowing.
23326 (mark_stack): Move local variables into the #ifdef region where
23328 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
23329 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
23331 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
23332 (GC_STRING_CHARS): Remove; not used.
23333 (Fmemory_limit): Cast sbrk's returned value to char *.
23335 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
23336 avoids undefined behavior in theory.
23338 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
23340 Use functions, not macros, for up- and down-casing (Bug#8254).
23341 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23342 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23343 to use the following functions instead of these macros.
23344 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23345 EMACS_INT, since callers assume the returned value fits in int.
23346 (upcase1): Likewise, for UPCASE_TABLE.
23347 (uppercasep, lowercasep, upcase): New static inline functions.
23348 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
23349 the race-condition problem in the old DOWNCASE.
23351 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

23357 which gcc can warn about.
23358 (regex_compile, re_match_2_internal): Mark locals as initialized.
23359 (RETALLOC_IF): Define only if needed.
23360 (WORDCHAR_P): Likewise. This one is never needed, but is used
23361 only in a comment talking about a compiler bug, so put inside
23362 the #if 0 of that comment.
23363 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23364 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
23367 * search.c (boyer_moore): Rename locals to avoid shadowing.
23368 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
23369 (PREV_CHAR_BOUNDARY): Likewise.

23379 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
23381 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
23382 Rename locals to avoid shadowing.
23383 (Fvertical_motion): Mark locals as initialized.
23385 * casefiddle.c (casify_object, casify_region): Now static.
23386 (casify_region): Mark local as initialized.
23388 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
23390 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23391 New macros, so that the caller can use some names other than
23392 gcpro1, gcpro2, etc.
23393 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23395 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23396 argument, for consistency with GCPRO2_VAR, etc: it is now the
23397 prefix of the variable, not the variable itself. All uses
23399 * dired.c (directory_files_internal, file_name_completion):
23400 Rename locals to avoid shadowing.
23402 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23403 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23404 dired.c's scmp function, had undefined behavior.
23405 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23406 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23407 * buffer.h: ... to here, because these macros use current_buffer,
23408 and the new implementation with inline functions needs to have
23409 current_buffer in scope now, rather than later when the macros
23411 (downcase, upcase1): New static inline functions.
23412 (DOWNCASE, UPCASE1): Reimplement using these functions.
23413 This avoids undefined behavior in expressions like
23414 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23415 from race conditions in accessing the global variables
23416 case_temp1 and case_temp2.
23417 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23418 * lisp.h (case_temp1, case_temp2): Remove their decls.
23419 * character.h (ASCII_CHAR_P): Move from here ...
23420 * lisp.h: ... to here, so that the inline functions mentioned
23421 above can use them.
23423 * dired.c (directory_files_internal_unwind): Now static.
23425 * fileio.c (file_name_as_directory, directory_file_name):
23426 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
23428 (file_name_as_directory): Use const pointers when appropriate.
23429 (Fexpand_file_name): Likewise. In particular, newdir might
23430 point at constant storage, so make it a const pointer.
23431 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23432 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23434 (Fset_file_times, Finsert_file_contents, auto_save_error):
23435 Rename locals to avoid shadowing.
23437 * minibuf.c (choose_minibuf_frame_1): Now static.
23438 (Ftry_completion, Fall_completions): Rename or remove locals
23439 to avoid shadowing.
23441 * marker.c (bytepos_to_charpos): Remove; unused.
23443 * lisp.h (verify_bytepos, count_markers): New decls,
23444 so that gcc does not warn that these functions aren't declared.
23446 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23447 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23448 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23449 (copy_text): Remove unused local var.
23451 * filelock.c (within_one_second): Now static.
23452 (lock_file_1): Rename local to avoid shadowing.
23454 * buffer.c (fix_overlays_before): Mark locals as initialized.
23455 (fix_start_end_in_overlays): Likewise. This function should be
23456 simplified by using pointers-to-pointers, but that's a different
23458 (switch_to_buffer_1): Now static.
23459 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23460 (report_overlay_modification): Rename locals to avoid shadowing.
23462 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
23463 Fix pointer signedness issue.
23464 (sys_subshell): Mark local as volatile if checking for lint,
23465 to suppress a gcc -Wclobbered warning that does not seem to be right.
23466 (MAXPATHLEN): Define only if needed.
23468 * process.c (serial_open, serial_configure): Move decls from here ...
23469 * systty.h: ... to here, so that they can be checked.
23471 * fns.c (get_random, seed_random): Move extern decls from here ...
23472 * lisp.h: ... to here, so that they can be checked.
23474 * sysdep.c (reset_io): Now static.
23475 (wait_for_termination_signal): Remove; unused.
23477 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
23478 (copy_keymap_item, append_key, push_text_char_description):
23480 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
23481 (DENSE_TABLE_SIZE): Remove; unused.
23482 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23483 (describe_map_tree):
23484 Rename locals to avoid shadowing.
23486 * keyboard.c: Declare functions static if they are not used elsewhere.
23487 (echo_char, echo_dash, cmd_error, top_level_2):
23488 (poll_for_input, handle_async_input): Now static.
23489 (read_char, kbd_buffer_get_event, make_lispy_position):
23490 (make_lispy_event, make_lispy_movement, apply_modifiers):
23491 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
23492 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
