6 (x_get_monitor_attributes_fallback)
7 (x_get_monitor_attributes_xinerama)
8 (x_get_monitor_attributes_xrandr, x_get_monitor_attributes):
9 Define only if USE_GTK.
10 (free_monitors): Define only if HAVE_XINERAMA || HAVE_XRANDR.
11 (x_get_monitor_attributes_fallback): Omit unused locals.
12 (x_get_monitor_attributes_xinerama, Fx_display_monitor_attributes_list):
13 Use double, not float, to avoid mixed-mode floating point arithmetic.

16 Jan Djärv <jan.h.d@swipnet.se>
18 * Makefile.in (XRANDR_LIBS, XRANDR_CFLAGS, XINERAMA_LIBS)
19 (XINERAMA_CFLAGS): New macros.
20 (ALL_CFLAGS, LIBES): Use them.
22 * xfns.c: Include <X11/extensions/Xrandr.h> if HAVE_XRANDR, and
23 include <X11/extensions/Xinerama.h> if HAVE_XINERAMA.
24 (Qgeometry, Qworkarea, Qmm_size, Qframes, Qsource): New variables.
25 (syms_of_xfns): DEFSYM them.

30 (x_get_monitor_attributes_xinerama): New functions.
31 (Fx_display_monitor_attributes_list): New primitive.
32 (syms_of_xfns): Defsubr it.
34 * xterm.h (x_display_info): Add Xatom_net_workarea and
35 Xatom_net_current_desktop.
37 * xterm.c (x_term_init): Initialize dpyinfo->Xatom_net_workarea
38 and dpyinfo->Xatom_net_current_desktop.
40 2013-05-06 Eli Zaretskii <eliz@gnu.org>
42 * xdisp.c (pos_visible_p): Use the special code for finding the
43 beginning of a display property or overlay for any "replacing"
44 display property, not just for display strings. This solves
45 incorrect reporting of position by posn-at-point. (Bug#14241)
47 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
49 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
50 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
51 Verify that ElfW (Half) fits in int.
52 (fatal): Use same signature as lisp.h.
53 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
54 configure and build with -DUNEXELF_DEBUG without worrying about
55 other modules that use DEBUG.
56 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
57 possibly-wide integers now uses it instead of plain fprintf.
58 (entry_address): New function, which avoids problems with 32-bit
59 overflow on 64-bit hosts.
60 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
61 (round_up): Don't assume the remainder fits in int.
62 (find_section): Use bool for boolean. Simplify debug code.
63 (unexec): Don't assume file sizes fit in int or size_t.
64 Omit unnecessary trailing newline in 'fatal' format.
65 Use strerror rather than outputting decimal error number.
66 Remove unused code when emacs is not defined;
67 this file relies on Emacs now.
68 Don't assume e_phnum and e_shnum are positive.
70 * regex.c: Fix problems when DEBUG is defined.
71 (extract_number, extract_number_and_incr): Define regardless of
72 whether DEBUG is defined; that's simpler and makes the code less
73 likely to go stale in the normal case when DEBUG is not defined.
74 Return int rather than taking an int * arg. All callers changed.
75 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
76 Remove, replacing with ...
77 (DEBUG_PRINT): New macro. All callers changed.
78 (DEBUG_COMPILES_ARGUMENTS): New macro.
79 (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
80 (print_compiled_pattern, print_double_string) [DEBUG]:
81 Use prototype rather than old-style definition.
82 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
83 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
84 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
85 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
86 Don't assume ptrdiff_t, size_t, and long are the same width as int.
87 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
88 This matters only when DEBUG is defined.
90 2013-05-05 Eli Zaretskii <eliz@gnu.org>
92 * xdisp.c (set_iterator_to_next): Set the
93 ignore_overlay_strings_at_pos_p flag only if we are _really_
94 iterating over an overlay string, as indicated by the
95 current.overlay_string_index member. (Bug#14306)
97 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
99 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
100 to where it is used, to avoid autorelease issues (Bug#14050).
102 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
104 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
105 * fileio.c (syms_of_fileio): Implement this.
106 * filelock.c (create_lock_file): If symbolic links don't work, so
107 we use a regular file as a lock file, do not fsync the lock file;
110 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
112 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.

123 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
124 assertion violations. (Bug#14062)
126 2013-05-01 David Reitter <david.reitter@gmail.com>
128 * nsfns.m (ns_tooltip): Initialize.
130 2013-04-28 Eli Zaretskii <eliz@gnu.org>
132 * coding.c (decode_coding_gap): Don't remove the character before
133 a newline unless it's a CR character. (Bug#14287)
135 2013-04-28 Dan Nicolaescu <dann@gnu.org>
137 * dispextern.h (struct face): Move enum face_underline_type

149 * callint.c (Fcall_interactively): Call `Qread_number' for
150 interactive code letter `n' instead of using duplicate code.
153 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
155 * systime.h (make_timeval): Declare as 'const'.

162 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
164 Port better to AIX (Bug#14258).
165 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
168 2013-04-24 Kenichi Handa <handa@gnu.org>
170 * coding.c (decode_coding_iso_2022): When an invalid escape
171 sequence is encountered, reset the invocation and designation
172 status to the safest one.
174 2013-04-22 Paul Eggert <eggert@cs.ucla.edu>
176 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
177 Without this fix, "make distclean" leaves stamp-h1 behind.
179 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
181 * w32fns.c (w32_fullscreen_rect): New function to compute the
182 window rectangle for the given fullscreen mode.
183 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
184 longer tunes the window size. This keeps the window's edges flush
185 with the screen and allows the taskbar to hide itself in fullboth.
187 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
188 window decorations and uses the entire screen.
190 * w32term.h (w32_fullscreen_rect) Add prototype.
191 (struct w32_output): Replace normal_width, normal_height,
192 normal_top, and normal_left members with a single normal_placement
194 (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP):
196 (FRAME_NORMAL_PLACEMENT): New macro.
198 2013-04-16 Juanma Barranquero <lekktu@gmail.com>
200 * minibuf.c (Ftest_completion): Silence compiler warning.
202 2013-04-15 Eli Zaretskii <eliz@gnu.org>
204 * w32fns.c (w32_wnd_proc): Add more assertions to investigate
207 * frame.h (WINDOW_FRAME): Protect macro and its argument with
210 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
211 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
212 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
213 parentheses where appropriate.
215 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
217 * keyboard.c (timer_start_idle): Remove no-longer-used local.
219 2013-04-14 Eli Zaretskii <eliz@gnu.org>
221 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
222 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
223 Mention in the doc string that setting these variables takes
224 effect only after a call to set-window-buffer. (Bug#14200)
226 2013-04-13 Eli Zaretskii <eliz@gnu.org>
228 * indent.c (Fvertical_motion): Don't consider display strings on
229 overlay strings as display strings on the buffer position we
230 started from. This prevents vertical cursor motion from jumping
231 more than one line when there's an overlay string with a display
232 property at end of line.
233 Reported by Karl Chen <Karl.Chen@quarl.org> in
234 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.
236 2013-04-12 Stefan Monnier <monnier@iro.umontreal.ca>
238 * window.c (select_window): `record_buffer' even if window is
239 already selected (bug#14191).
241 2013-04-11 Eli Zaretskii <eliz@gnu.org>
243 * window.c (Fwindow_end): Test more flags, including the buffer's
244 last_overlay_modified flag, to determine whether the window's
245 display is really up-to-date. Prevents the function from
246 returning a stale value. (Bug#14170)
247 (Fwindow_line_height): Fix the test for up-to-date-ness of the
250 2013-04-10 Eli Zaretskii <eliz@gnu.org>
252 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
253 garbaged only if it is not already the top frame on its TTY.
254 This prevents flickering due to constant redrawing of TTY frames when
255 there are GUI frames open in the same session. (Bug#13864)
257 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
259 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
260 of marking the idle timers directly.
262 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
264 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
267 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>
269 * window.c (select_window): Don't record_buffer while the invariant is
270 temporarily broken (bug#14161).

284 2013-03-31 Jan Djärv <jan.h.d@swipnet.se>
286 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
289 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
291 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
292 This bug was introduced by my 2013-02-25 change that simplified
293 data_start configuration. Without this change, on GNU/Linux
294 an Emacs configured with --enable-profiling fails immediately
295 due to a profiler signal.
296 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
297 with these flags. On platforms where special flags are needed
298 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
299 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
300 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
302 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>
304 Get rid of some platform-specific functions examining window
305 system and its capabilities. This is a partial rework of the
307 * lisp.h (have_menus_p): Remove prototype. This function is
308 replaced with platform-independent window_system_available.
309 (check_window_system): Move to...
310 * frame.h (decode_window_system_frame, window_system_available):
311 ...here, add new prototypes.

317 * w32term.h (check_x_frame):
318 * nsterm.h (check_x_frame): Remove prototypes. This function
319 is replaced with platform-independent decode_window_system_frame.
320 * msdos.c (have_menus_p): Remove.
321 * nsfns.m (check_window_system, have_menus_p, check_ns_frame):
322 Remove platform-specific functions. Use check_window_system,
323 decode_window_system_frame and check_ns_display_info where
324 appropriate. Minor style and comment tweaks.

339 changed. Check EOL format. Do not call adjust_coding_eol_type
341 (check_utf_8): New function.
342 (adjust_coding_eol_type): Do nothing if already adjusted.
343 (detect_coding): Compare the return value of check_ascii with
344 coding->src_bytes. Call adjust_coding_eol_type if necessary.
345 (decode_coding_gap): Optimize for valid UTF-8.
347 2013-03-21 Kenichi Handa <handa@gnu.org>
349 * coding.c (syms_of_coding): Cancel previous change.
351 * insdel.c (insert_from_gap): Fix previous change.
353 2013-04-05 Dmitry Antipov <dmantipov@yandex.ru>
355 Consistently use platform-specific function to detect window system.

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

403 Prefer < to > for range checks.
404 * dispnew.c (sit_for): Don't mishandle NaNs.
405 This fixes a bug introduced in the 2013-03-24 change.
406 * editfns.c (decode_time_components): Don't hoist comparison.
407 This fixes another bug introduced in the 2013-03-24 change.

461 2013-03-28 Dmitry Antipov <dmantipov@yandex.ru>
463 * window.h (struct window): Replace hchild, vchild and buffer slots
464 with the only contents slot. This is possible because each valid
465 window may have either the child window (in vertical or horizontal
466 combination) or buffer to display (for the leaf window). Using that,
467 a lof of operations to traverse and/or change window hierarchies may
468 be simplified. New member horizontal is used to distinguish between
469 horizontal and vertical combinations of internal windows.

694 'fullscreen' parameter. Always record previous width and height
695 of the frame, except when switching out of maximized modes, so
696 that they could be restored correctly, instead of resetting to the

845 * coding.h (struct coding_system): New member eol_seen.
847 * coding.c (detect_ascii): New function.
848 (detect_coding): Set coding->head_ascii and coding->eol_seen only
849 when the source bytes are actually scanned. On detecting for

851 source bytes directly.
852 (produce_chars): Call insert_from_gap with the new arg 0.
853 (encode_coding): Likewise.
854 (decode_coding_gap): Control ASCII optimization by the variable

887 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
888 too so that these builds can use Cygwin's file conversion
889 functions. (We've been building and linking cygw32.o all along
890 and just not using it.)
892 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

905 * w32term.c (w32_read_socket): If the Emacs frame is being
906 activated, call w32fullscreen_hook, to make sure the new frame
907 dimensions are in effect. (Bug#13937)
909 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
911 * xdisp.c (init_iterator): Simplify because both character and byte
912 positions are either specified or -1. Add eassert. Adjust comment.
913 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
914 character and byte positions can be obtained from marker.

934 Include <sys/param.h> unconditionally, as that works elsewhere and
935 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
936 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
939 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>
941 * insdel.c (adjust_after_replace): Use bool for boolean.
943 2013-03-11 Stefan Monnier <monnier@iro.umontreal.ca>

1023 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1024 from Elisp via unread-command-events.
1026 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1027 functions to mean "no change".

1037 (search_regs_saved, Fregexp_quote):
1038 Use bool for boolean.
1039 * region-cache.c (region_cache_forward, region_cache_backward):
1040 Fix comments to match code: these functions return int, not boolean.
1042 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1044 * search.c (find_newline): Accept start and end byte positions
1045 as arguments and allow -1 if not known.

1047 * lisp.h (find_newline, find_newline_no_quit): Adjust prototype.
1048 * bidi.c (bidi_find_paragraph_start): Pass byte position to

1080 to match other functions accepting character and byte positions.
1082 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

1084 when you need just to move to the previous buffer position.
1085 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1087 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1160 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1162 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1163 * sysdep.c (list_system_processes)
1164 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1165 Make it a stub in this case; otherwise the build might fail,
1166 and this code hasn't been tested on such hosts anyway.
1167 Problem reported by Nelson H. F. Beebe in
1168 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1169 and analyzed by Jérémie Courrèges-Anglas in
1170 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1172 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1174 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1175 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1176 (get_visually_first_element, move_it_vertically_backward): Ajust users.
1177 * bidi.c (bidi_find_paragraph_start): Likewise.
1178 * indent.c (vmotion): Likewise.
1180 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1182 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1183 * filelock.c: Include <c-ctype.h>.
1184 (MAX_LFINFO): New top-level constant.
1185 (lock_info_type): Remove members pid, boot_time. Add members at,
1186 dot, colon. Change user member to be the entire buffer, not a
1187 pointer. This allows us to handle the case where a foreign
1188 pid or boot time exceeds the local range. All uses changed.
1189 (LINKS_MIGHT_NOT_WORK): New constant.
1190 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1191 (defined_WINDOWSNT): Remove.
1192 (MAKE_LOCK_NAME, file_in_lock_file_name):
1193 Always use .#FILE (not .#-FILE) for the file lock,
1194 even if it is a regular file.
1195 (rename_lock_file): New function.
1196 (create_lock_file): Use it.
1197 (create_lock_file, read_lock_data):
1198 Prefer a symbolic link for the lock file, falling back on a
1199 regular file if symlinks don't work. Do not try to create
1200 symlinks on MS-Windows, due to security hassles. Stick with
1201 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1202 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1203 host may be using a Windowsish file system, and cannot use
1204 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1205 doesn't work. Don't fail merely because of a symlink-contents
1206 length limit in the current file system; fall back on regular
1207 files. Increase the symlink contents length limit to 8 KiB, this
1208 should be big enough for any real use and doesn't crunch the
1210 (create_lock_file, lock_file_1, read_lock_data):
1211 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1212 (lock_file_1): Return error number, not bool. All callers changed.
1213 (ELOOP): New macro, if not already defined.
1214 (read_lock_data): Return size of lock file contents, not Lisp object.
1215 All callers changed. Handle a race condition if some other process
1216 replaces a regular-file lock with a symlink lock or vice versa,
1217 while we're trying to read the lock.
1218 (current_lock_owner): Parse contents more carefully, to help avoid
1219 confusing a regular-file lock with some other application's use
1220 of the file. Check for lock file contents being too long, or
1221 not parsing correctly.
1222 (current_lock_owner, lock_file):
1223 Allow foreign pid and boot times that exceed the local range.
1224 (current_lock_owner, lock_if_free, lock_file):
1225 Simplify allocation of lock file contents.
1226 * w32.c (sys_rename_replace): New function, containing most of
1227 the contents of the old sys_rename.
1228 (sys_rename): Use it.
1229 (fchmod): New dummy function.
1230 * w32.h (sys_rename_replace, fchmod): New decls.
1232 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1234 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1235 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1236 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1237 <dmantipov@yandex.ru>.
1239 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1241 * composite.c (get_composition_id, fill_gstring_header):
1242 Use make_uninit_vector where appropriate.
1243 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1244 * xselect.c (clean_local_selection_data): Likewise.
1246 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1248 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1249 * image.c (imagemagick_load_image): Calculate height and width
1250 after flattening the image, not before.
1252 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1254 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1255 * ftfont.c (ftfont_shape_by_flt): Likewise.
1256 * w32uniscribe.c (uniscribe_shape): Likewise.
1258 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1260 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1261 The old approach, which fell back on DIR/.#FILE.0 through
1262 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1263 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1264 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1265 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1266 because the locking mechanism was never reliable in that case).
1267 This patch fixes this and other bugs discovered by a code
1268 inspection that was prompted by
1269 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1270 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1271 to avoid interoperability problems between the MS-Windows and
1272 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1273 instances of Emacs now ignore each others' locks.
1274 * filelock.c (defined_WINDOWSNT): New constant.
1275 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1276 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1277 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1278 regular files on MS-Windows hosts.
1279 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1280 Use SAFE_ALLOCA to avoid problems with long file names.
1281 (MAX_LFINFO): Now a local constant, not a global macro.
1282 (IS_LOCK_FILE): Remove.
1283 (lock_file_1): Don't inspect errno if symlink call succeeds;
1284 that's not portable.
1285 (lock_file): Document that this function can return if lock
1287 (lock_file): Don't access freed storage.
1289 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

1293 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1295 * textprop.c: Use bool for booleans.
1296 (validate_interval_range, Fadd_text_properties)
1297 (Fremove_text_properties): Prefer bool to int when either works.
1299 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1301 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1302 If the interval tree changes as a side effect of calling
1303 modify_region, re-do processing starting from the call to
1304 validate_interval_range. (Bug#13743)
1306 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1308 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1311 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1313 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1314 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1315 access to the lock file until it is written and closed.
1318 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1320 * callint.c (Qcall_interactively):
1321 * macros.c (Qexecute_kbd_macro):

1330 Minor textprop integer cleanup.
1331 * intervals.h, textprop.c (add_text_properties_from_list):
1332 Return void, not int, since nobody uses the return value.
1333 * textprop.c (validate_plist, add_properties, remove_properties)
1334 (Fadd_text_properties):
1335 Don't assume list length fits in int.
1336 (interval_has_all_properties, interval_has_some_properties)
1337 (interval_has_some_properties_list, add_properties, remove_properties)
1338 (Fadd_text_properties, Fremove_text_properties)
1339 (Fremove_list_of_text_properties, text_property_stickiness):
1340 Use bool for booleans.
1341 (Fadd_text_properties, Fremove_text_properties):
1342 (Fremove_list_of_text_properties):
1343 Reindent do-while as per GNU style.
1345 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1347 Implement CLASH_DETECTION for MS-Windows.
1349 * filelock.c [WINDOWSNT]: Include w32.h.
1350 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1351 function of that name. Up-case the macro arguments.
1352 (IS_LOCK_FILE): New macro.
1353 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1354 (create_lock_file): New function, with body extracted from
1356 [WINDOWSNT]: Implement lock files by writing a regular file with
1357 the lock information as its contents.
1358 (read_lock_data): New function, on Posix platforms just calls
1360 [WINDOWSNT]: Read the lock info from the file.
1361 (current_lock_owner): Call read_lock_data instead of calling
1362 emacs_readlinkat directly.
1363 (lock_file) [WINDOWSNT]: Run the file name through
1366 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1367 just check if the process by that PID exists.
1369 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1370 also present, as doing so will fail to error out if the file
1373 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1375 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1376 (Fremove_list_of_text_properties): Skip all of the intervals in
1377 the region between START and END that already have resp. don't
1378 have the requested properties, not just the first one.
1379 Add assertions that the loop afterwards always modifies the
1380 properties. (Bug#13743)
1382 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1384 * callint.c (Fcall_interactively): Use the right lexical environment
1385 for `interactive' specs (bug#13811).

1388 2013-02-25 Paul Eggert <eggert@cs.ucla.edu>
1390 Simplify data_start configuration (Bug#13783).
1391 This is a followon simplification to the fix for Bug#13650.
1392 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
1393 (START_FILES): Remove. All uses removed.
1394 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
1395 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.

1402 Do not depend on mem-limits.h.
1403 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
1404 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)

1410 * vm-limit.c: Move most of mem-limits.h's contents here.
1411 (data_start): New decl. It's OK if this is approximate,
1412 so simplify-away some unnecessary exactness.
1413 (POINTER): Remove; all uses removed.
1414 (data_space_start): Now char *, to avoid casts.
1415 (exceeds_lisp_ptr): New function, replacing the old
1416 EXCEEDS_LISP_PTR macro. All uses changed.
1417 (check_memory_limits): Simplify and remove casts.
1418 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.
1419 (memory_warnings): Use data_start instead of start_of_data.

1443 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1445 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.

1461 2013-02-19 Daniel Colascione <dancol@dancol.org>
1463 * sheap.c (report_sheap_usage): Use message, not message1, so
1464 that we don't try to create a buffer while we're in the middle
1465 of dumping Emacs. Explain why.
1467 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1469 * search.c (find_newline): Return byte position in bytepos.

1482 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1484 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1485 resources were not orderly released.
1487 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1489 * xdisp.c (x_draw_vertical_border): For a window that is neither

1516 unconditionally. (Bug#9066)
1518 * w32.c (set_errno): Reset h_errno and don't set it to any other
1519 value. Set errno instead.

1532 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1534 * keyboard.c (read_char): Fix calculation of auto-save time out
1535 when auto-save-timeout is less than 4. (Bug#13720)

1564 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1566 Fix AIX port (Bug#13650).
1567 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1568 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1569 was #undeffed earlier, so it cannot be used as a macro here.
1570 Use the constant and not the macro.
1572 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1574 * w32proc.c (new_child): If no vacant slots are found in
1575 child_procs[], make another pass looking for slots whose process
1576 has exited or died. (Bug#13546)

1579 MAXDESC, set errno to EMFILE.
1580 (_sys_read_ahead): Update cp->status when failing to read serial
1581 communications input, so that the status doesn't stay at
1582 STATUS_READ_IN_PROGRESS. (Bug#13546)
1584 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1586 * gtkutil.c (tb_size_cb): New function.

1596 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1598 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1608 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1610 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1612 Improve AIX port some more (Bug#13650).
1613 With this, it should be as good as it was in 23.3, though it's
1614 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1615 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1616 * unexaix.c (start_of_text): Remove.
1617 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1618 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1619 (orig_load_scnptr, orig_data_scnptr):
1620 Now off_t, not long, since they are file offsets.
1621 (make_hdr): Use _data, not start_of_data ().
1622 This is the key part of the fix.
1623 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1624 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1626 * pre-crt0.c (data_start): Initialize to 1.
1627 This ports to compilers that optimize the external declaration
1628 'int x = 0;' as if it were 'int x;' to shrink the executable.
1630 Improve AIX port (Bug#13650).
1631 This doesn't fix the bug, but it makes progress: Emacs builds now.
1632 * unexaix.c: Include inttypes.h, stdarg.h.
1633 (report_error, report_error_1): Mark as _Noreturn.
1634 (report_error): Don't report the wrong errno.
1635 (report_error_1): Now varargs. All callers changed.
1636 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1637 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1638 (write_ptr): Use %p to print address rather than %lx and a cast
1639 to unsigned long. Grow buffer a bit, to be safer.
1641 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1643 * bidi.c (bidi_resolve_neutral): After finding the next
1644 non-neutral character, accept NEUTRAL_ON type as well, because
1645 directional control characters, such as LRE and RLE, have their
1646 type converted to that by bidi_resolve_weak. This avoids aborts
1647 when LRE/RLE follows a run of neutrals.
1648 (bidi_move_to_visually_next): Assert that return value of
1649 bidi_peek_at_next_level is non-negative. Negative values will
1652 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1654 Minor getenv-related fixes.
1655 * callproc.c (Fcall_process_region) [!DOS_NT]:
1656 Avoid unnecessary duplicate call to getenv.
1657 * callproc.c (init_callproc):
1658 * dispnew.c (init_display):
1659 * sysdep.c (sys_subshell):
1660 Omit unnecessary cast of getenv or egetenv.
1662 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1664 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1665 Update dependencies.
1667 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1669 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1671 (display_line): Set w->region_showing to the value of
1672 it->region_beg_charpos, not to -1. This fixes redisplay
1673 optimization when cursor is moved up after M->. (Bug#13623)
1675 (try_scrolling): Scroll text up more if point is too close to ZV
1676 and inside the scroll margin. This makes sure point is moved
1677 outside the scroll margin in these cases.
1679 * window.h (struct window): region_showing can no longer be
1682 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1684 Tune by using memchr and memrchr.
1685 * doc.c (Fsnarf_documentation):
1686 * fileio.c (Fsubstitute_in_file_name):
1687 * search.c (find_newline, scan_newline):
1688 * xdisp.c (pos_visible_p, display_count_lines):
1689 Use memchr and memrchr rather than scanning byte-by-byte.
1690 * search.c (find_newline): Rename from scan_buffer.
1691 Omit first arg TARGET, as it's always '\n'. All callers changed.
1693 Clean up read_key_sequence a tiny bit more.
1694 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1695 (read_key_sequence): Remove unused locals.
1697 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1699 Clean up read_key_sequence a bit; reread active keymaps after first event.
1700 * keyboard.c (read_char, read_char_x_menu_prompt)
1701 (read_char_minibuf_menu_prompt):
1702 Replace nmaps+maps with a single `map' arg.
1703 (follow_key): Operate on a single map.
1704 (active_maps): New function.
1705 (test_undefined): Also return true for nil bindings.
1706 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1707 a single (composed) keymap. Remember `first_event' to choose the right
1708 set of active keymaps. Recompute the set of keymaps after receiving
1709 the first event. Remove GOBBLE_FIRST_EVENT.
1710 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1711 * keyboard.h (read_char): Update declaration.
1712 * lread.c (read_filtered_event): Adjust call to read_char.
1714 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1716 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1717 Don't use the limitation on backwards movement when lines are truncated
1718 in the window. (Bug#13675)
1720 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1722 * marker.c (set_marker_internal): If desired position is passed
1723 as a marker, avoid call to buf_charpos_to_bytepos.
1724 * window.c (Fset_window_point): Omit redundant type checking.
1725 (Fset_window_start): Likewise. Format comment.
1726 (window_scroll_pixel_based): Use set_marker_restricted_both
1727 with character and byte positions obtained from an iterator.
1728 (Fset_window_configuration): Use set_marker_restricted_both.
1729 * xdisp.c (message_dolog): Likewise.
1731 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1733 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1734 When text lines are longer than window's screen lines, don't move back
1735 too far. This speeds up some redisplay operations. (Bug#13675)
1737 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1739 * syntax.c (scan_sexps_forward): Fix byte position calculation
1740 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1742 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1744 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1745 that was not needed.
1747 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1749 Minor hashing refactoring.
1750 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1751 (sxhash_float): Return EMACS_UINT, for consistency with the other
1753 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1754 non-static inline function and therefore can't use static vars.
1755 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1756 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1757 with the other hash functions.
1759 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1761 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1762 XXXXXX part of the temporary file pattern is not downcased even
1763 when w32-downcase-file-names is non-nil. (Bug#13661)
1765 * xdisp.c (decode_mode_spec): Remove handling of %t.

1851 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1853 * xdisp.c (window_buffer_changed): region_showing can be negative,

1866 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1867 daemon mode works on cygw32 when Emacs is installed and not just
1870 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1872 Avoid file time stamp bug on MS-Windows (Bug#13149).
1873 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1874 as FAT32 doesn't update time stamps when truncating them.
1875 Also, check that a file time stamp is not a multiple of 100 ns;
1876 this should catch all instances of the problem on MS-Windows,
1877 as its native file system resolution is 100 ns or worse, and
1878 checking for a non-multiple of 100 ns should impose only a small
1879 overhead on systems with ns resolution.
1881 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1883 Avoid encoding file names on MS-Windows when they need to be run
1884 through dostounix_filename.
1885 * w32.c (normalize_filename): Accept an additional argument
1886 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1887 downcase it even if w32-downcase-file-names is non-nil.
1888 (dostounix_filename): Accept an additional argument MULTIBYTE and
1889 pass it to normalize_filename.
1890 (emacs_root_dir): Adjust.
1892 * msdos.h (dostounix_filename): Adjust prototype.
1894 * w32.h (dostounix_filename): Adjust prototype.
1896 * msdos.c (dostounix_filename): Accept an additional argument and
1898 (init_environment): Adjust callers of dostounix_filename.
1900 * fileio.c (Ffile_name_directory, file_name_as_directory)
1901 (directory_file_name, Fexpand_file_name)
1902 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1904 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1906 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1907 variables, as egetenv is case-insensitive for DOS_NT.
1909 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1910 with an encoded file name.
1912 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1913 Adjust calls to dostounix_filename.
1915 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1917 * unexw32.c (unexec): Adjust call to dostounix_filename.
1919 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1921 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1924 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1927 * callproc.c (Fcall_process): Make sure program name in PATH and
1928 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1929 is passed to exec/spawnve, which fails unless the file-name
1932 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1933 even if w32-quote-process-args is nil.
1935 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1937 Fix timestamp bug when write-region appends nothing (Bug#13149).
1938 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1939 the file's time stamp doesn't change if Emacs happens to write nothing
1940 to the file, and on a buggy file system this could cause Emacs to
1941 incorrectly infer that the file system doesn't have the bug.
1942 Avoid this problem by inhibiting the inference in this case.
1944 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1946 * window.h (struct window): Convert base_line_number, base_line_pos
1947 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1948 Convert region_showing member from Lisp_Object to bitfield.
1949 Remove sequence_number member. Adjust comments.
1950 * window.c (sequence_number): Remove.
1951 (make_window): Initialize column_number_displayed.
1952 * print.c (print_object): Follow the printed representation of
1953 frames and print window pointer to distinguish between windows.
1954 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1955 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1956 (wset_column_number_displayed, wset_region_showing): Remove.
1957 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1958 (try_scrolling, try_cursor_movement, redisplay_window)
1959 (try_window_reusing_current_matrix, try_window_id, display_line)
1960 (display_mode_lines, decode_mode_spec): Adjust users.
1961 * .gdbinit (pwinx): Do not print sequence_number.
1963 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1965 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1966 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1967 * dired.c: Include <fcntl.h>.
1968 (open_directory): New function, which uses open and fdopendir
1969 rather than opendir. DOS_NT platforms still use opendir, though.
1970 (directory_files_internal, file_name_completion): Use it.
1971 (file_attributes): New function, with most of the old Ffile_attributes.
1972 (directory_files_internal, Ffile_attributes): Use it.
1973 (file_attributes, file_name_completion_stat): First arg is now fd,
1974 not dir name. All uses changed. Use fstatat rather than lstat +
1976 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1977 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1978 (emacs_readlinkat): New function, with much of the old
1979 Ffile_symlink_p, but with an fd argument for speed.
1980 It uses readlinkat rather than careadlinkatcwd, so that it
1981 need not assume the working directory.
1982 (Ffile_symlink_p): Use it.
1983 * filelock.c (current_lock_owner): Use emacs_readlinkat
1984 rather than emacs_readlink.
1985 * lisp.h (emacs_readlinkat): New decl.
1986 (READLINK_BUFSIZE, emacs_readlink): Remove.
1987 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1988 (emacs_norealloc_allocator, emacs_readlink): Remove.
1989 This stuff is moved to fileio.c.
1990 * w32.c (fstatat, readlinkat): New functions.
1991 (careadlinkat): Don't check that fd == AT_FDCWD.
1992 (careadlinkatcwd): Remove; no longer needed.
1994 2013-01-31 Glenn Morris <rgm@gnu.org>
1996 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1997 (Fwrite_region): Update for new choose_write_coding_system args.
1998 Move the last piece of choose_write_coding_system here. (Bug#13522)
1999 (syms_of_fileio): Add choose-write-coding-system.
2001 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2003 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2004 (sys_close): Zero out the flags for the file descriptor before
2005 closing it. (Bug#13546)
2007 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2008 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2009 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2012 * w32.c (w32_get_long_filename, init_environment, readlink):
2013 Support file names encoded in DBCS codepages.
2014 (readlink): Use the current file-name-coding-system, not the ANSI
2015 codepage, to decode and handle targets of symlinks.
2017 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2019 * w32.c (opendir): Now accepts a 'const char *'.
2021 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2023 Remove obsolete redisplay code. See the discussion at
2024 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2025 * dispnew.c (preemption_period, preemption_next_check): Remove.
2026 (Vredisplay_preemption_period): Likewise.
2027 (update_frame, update_single_window, update_window, update_frame_1):
2028 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2029 used, following the 2012-06-22 change.
2031 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2033 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2035 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2037 * font.c (num_fonts): Remove the leftover from old
2038 debugging code. Adjust comment style here and there.
2039 * insdel.c (insert_1): Remove.
2040 * lisp.h (insert_1): Remove prototype.
2041 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2043 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2045 * w32.c (max_filename_mbslen): New function.
2046 (normalize_filename, readdir): Use it to detect locales where ANSI
2047 encoding of file names uses a double-byte character set (DBCS).
2048 If a DBCS encoding is used, advance by characters using
2049 CharNextExA, instead of incrementing a 'char *' pointer.
2050 Use _mbslwr instead of _strlwr. (Bug#13515)
2052 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2053 request of memory reservation to 1.7GB. (Bug#13065)
2055 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2057 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2058 at check_extra_latin label. (Bug#13505)
2060 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2062 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2063 Avoid redundant calls to strlen.
2065 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2067 Drop async_visible and async_iconified fields of struct frame.
2068 This is possible because async input is gone; for details, see
2069 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2070 * frame.h (struct frame): Remove async_visible and async_iconified
2071 members, convert garbaged to unsigned bitfield. Adjust comments.
2072 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2073 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2074 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2075 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2076 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2078 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2079 properly. Likewise for obscured.
2081 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2084 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2086 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2088 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2089 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2091 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2093 * xdisp.c (message2, message2_nolog): Remove functions.
2094 (message3, message3_nolog): Extract nbytes and multibyteness directly
2095 from the string. Change all callers.
2096 (message3_nolog): Don't set message_enable_multibyte since set_message
2097 will reset it anyway.
2098 (message1, message1_nolog): Use message3.
2099 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2100 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2101 (set_message): Drop all but the second arg, which has to be a string.
2102 (set_message_1): Simplify now that we know that a1 is NULL and the
2103 second arg is a string.
2104 * frame.h (struct frame): Remove `message_buf' field.
2105 Use glyphs_initialized_p instead.
2106 (FRAME_MESSAGE_BUF): Remove macro.
2107 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2108 * lisp.h (message2, message2_nolog): Remove declarations.
2109 (message3, message3_nolog): Update declarations.
2110 * keyboard.c (read_char_minibuf_menu_text)
2111 (read_char_minibuf_menu_width): Remove vars.
2112 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2113 to correctly handle multibyte strings.
2114 * frame.c (delete_frame): Don't free message_buf any more.
2115 * editfns.c (message_text, message_length): Remove vars.
2116 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2117 * fileio.c (auto_save_error): Use message3 instead of message2.
2118 * dispnew.c (adjust_frame_message_buffer): Remove function.
2120 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2122 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2123 real estate used for the tool bar and the menu bar.
2125 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2127 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2128 hidden buffer is prepared to modification (Bug#13164).
2130 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2132 * window.h (struct window): Change window_end_valid member from
2133 Lisp_Object to a bitfield. Adjust comments.
2134 (wset_window_end_valid): Remove.
2135 * window.c (adjust_window_count): Clear window_end_valid.
2136 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2137 (Fwindow_line_height, set_window_buffer, Frecenter)
2138 (Fsplit_window_internal, Fdelete_other_windows_internal)
2139 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2140 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2141 * xdisp.c (check_window_end, reconsider_clip_changes)
2142 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2143 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2144 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2146 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2148 * xdisp.c (mark_window_display_accurate): Simplify the loop
2149 assuming that the only one of vchild, hchild or buffer window
2150 slots is non-nil. Call mark_window_display_accurate_1 for
2151 the leaf windows only.
2152 (mark_window_display_accurate_1): Always assume leaf window.
2155 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2157 * emacs.c (Qkill_emacs_hook): Now static.
2159 * fileio.c (Finsert_file_contents): Simplify.
2160 Remove unnecessary assignments and tests.
2162 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2164 * w32.c (acl_set_file): Don't test for errors unless
2165 set_file_security returns FALSE. Avoids spurious errors when
2168 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2170 * fileio.c (Finsert_file_contents): Revert code introduced at
2171 2013-01-18 in favor of the simpler and generally better fix.
2172 Save stack space by removing 'buffer' and reusing 'read_buf'
2175 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2177 * lisp.h (eabs): Define unconditionally (Bug#13419).
2178 The old "#if !defined (eabs)" was an unnecessary revenant of back
2179 when this macro was called "abs". Document 'eabs' better.
2181 2013-01-19 Glenn Morris <rgm@gnu.org>
2183 * fns.c (Frandom): Doc fix.
2185 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2187 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2188 segfault when there are lots of overlays.
2190 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2191 when there are lots of overlays.
2192 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2193 for the details and a way to reproduce.
2195 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2197 * fileio.c: Use O_APPEND to append.
2198 This corresponds better to the natural interpretation of "append",
2199 and avoids the need to open the output file twice, or to invoke
2200 lseek when APPEND is neither nil nor a number.
2201 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2202 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2203 file possibly twice, and lseeking to its end; this avoids the
2204 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2205 at the same time: the combination is never needed and apparently
2206 it doesn't work with DOS_NT.
2208 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2209 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2211 Allow floating-point file offsets.
2212 Problem reported by Vitalie Spinu in
2213 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2214 * fileio.c (emacs_lseek): Remove.
2215 (file_offset): New function.
2216 (Finsert_file_contents, Fwrite_region): Use it.
2218 2013-01-19 Chong Yidong <cyd@gnu.org>
2220 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2221 aborting on Fsignal (Bug#13289).
2223 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2225 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2226 set_file_security as failure due to insufficient privileges.
2227 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2228 (fstat): Return owner and group like 'stat' and 'lstat' do.
2230 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2232 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2233 The bug was observed on Ubuntu operating inside a virtual machine,
2234 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2235 The workaround introduces a race condition on non-buggy hosts,
2236 but it's an unlikely race and anyway there's a nearly identical
2237 nearby race that can't be fixed.
2238 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2240 (Fwrite_region): Test for file system time stamp bug.
2241 (init_fileio): New function.
2242 * lisp.h (init_fileio): Declare it.
2243 * emacs.c (main): Call it.
2245 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2246 and make it more consistent with other stat-failure diagnostics.
2248 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2250 Fix crash when inserting data from non-regular files.
2251 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2252 for the error description produced by valgrind.
2253 * fileio.c (read_non_regular): Rename to read_contents.
2254 Free Lisp_Save_Value object used to pass parameters.
2255 (read_non_regular_quit): Rename to read_contents_quit.
2256 (Finsert_file_contents): Redesign internal file reading loop to adjust
2257 gap and end positions after each read and so help make_gap to work
2258 properly. Do not signal an I/O error too early and so do not leave
2259 not yet decoded characters in a buffer, which was the reason of
2260 redisplay crash. Use list2 to build return value. Adjust comments.
2262 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2264 Close a race when statting and reading files (Bug#13149).
2265 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2266 This avoids a race if the file is renamed between stat and open.
2267 This race is not the problem originally noted in Bug#13149;
2268 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2270 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
2272 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
2273 objects, related functions and macros.
2274 (make_save_value): Adjust prototype.
2275 (make_save_pointer): New prototype.
2276 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
2277 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2278 * alloc.c (format_save_value): Rename to make_save_value.
2279 (make_save_pointer): New function.
2280 (record_xmalloc): Use make_save_pointer.
2281 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2282 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2283 Change users of make_save_value to make_save_pointer.
2284 Likewise for format_save_value and make_save_value.
2286 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
2288 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
2289 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
2290 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
2293 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
2295 * alloc.c (free_save_value): Now static.
2297 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2299 * keymap.c (map_keymap_internal): Use format_save_value.
2300 (map_keymap_char_table_item): Adjust accordingly.
2301 * fileio.c (non_regular_fd, non_regular_inserted)
2302 (non_regular_nbytes): Remove.
2303 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2304 Use format_save_value to pass parameters to read_non_regular.
2305 (read_non_regular): Use XSAVE_ macros to extract parameters.
2307 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2309 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2311 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2313 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2314 extraction from any Lisp_Save_Value slot. Add type checking.

2367 * editfns.c (save_excursion_save): Pack everything within
2368 Lisp_Save_Value and so avoid xmalloc.
2369 (save_excursion_restore): Adjust to match new layout. Use free_misc
2370 because we do not allocate extra memory any more. Add eassert.
2371 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2372 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

2384 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
2386 Fix SIGDANGER handlers, for AIX (Bug#13408).
2387 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

2440 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2442 Avoid unnecessary byte position calculation for the gap movement.
2443 Since all users of move_gap do CHAR_TO_BYTE for other purposes

2454 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
2456 * term.c (init_tty): Use them instead of rolling our own code.
2457 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2458 switches from 'signal' to 'pthread_sigmask', which is safer in
2459 multithreaded applications.
2460 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2461 which has already arranged for that.
2462 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2463 This is the main part of the bug fix.

2473 the type of per-buffer values where appropriate.
2474 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
2475 predicate, which is how it's really used now. Adjust comment.
2476 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2477 * buffer.c (buffer_slot_type_mismatch): Remove.
2478 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
2479 predicate. Adjust comment.

2482 left-margin-width, right-margin-width, left-fringe-width,
2483 right-fringe-width, scroll-bar-width and buffer-display-count.
2484 Use Qstringp for default-directory, buffer-file-name,
2485 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2486 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
2488 * data.c (store_symval_forwarding): Adjust to call the predicate.

2505 (make_gap_1): New function to adjust the gap of any buffer.
2506 * coding.c (coding_alloc_by_making_gap): Use it.
2507 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,

2531 trailing dash is properly added.
2533 2013-01-05 Eli Zaretskii <eliz@gnu.org>
2535 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
2536 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2537 digits for buffer positions, before misalignment starts.
2538 Display "0" for integer "object" field.
2539 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2540 Display the newline glyph more unambiguously.
2542 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2544 * nsterm.m (ns_draw_underwave):
2545 * w32term.c (w32_draw_underwave):
2546 * xterm.c (x_draw_underwave): Make underwave look more triangular
2547 and also degrade gracefully for small fonts. (Bug#13000)
2549 * nsterm.m (ns_draw_text_decoration):
2550 * w32term.c (x_draw_glyph_string):
2551 * xterm.c (x_draw_glyph_string): Don't use previous underline
2552 thickness and position if previous underline type is underwave.
2554 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
2556 * fileio.c (Ffile_acl): Undocument return format.
2558 2013-01-02 Glenn Morris <rgm@gnu.org>
2560 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

2570 * lread.c (read_list):
2571 * minibuf.c (Ftry_completion):
2572 * term.c (tty_ins_del_lines):
2573 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2574 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2576 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2578 * w32.c (unsetenv): Set up the string passed to _putenv
2580 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2581 for the bug this caused.
2583 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2585 * coding.c (Qmac): Now static.
2587 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2589 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2590 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

2597 by TOOLBAR_TOP_WIDGET.
2598 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2599 Check toolbar_is_packed.
2600 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2601 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2602 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2604 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2605 (xg_update_menubar): Update title only if
2606 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2607 (xg_update_submenu): Skip tearoff only if
2608 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2609 (xg_initialize): Initialize xg_detached_menus only if
2610 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2612 * xterm.h (struct x_output): Surround handlebox_widget with
2613 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2614 toolbar_in_hbox is bool.
2616 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2618 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2619 (LIBS_GNUSTEP): Define.
2620 (LIBES): Add $(LIBS_GNUSTEP).
2621 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
2623 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2625 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2626 continuation glyph on a TTY with an indication of an empty line.
2629 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2631 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2632 file's SELinux context or ACLs successfully set, nil otherwise.
2634 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
2636 * w32proc.c (reader_thread): Avoid passing NULL handles to
2637 SetEvent and WaitForSingleObject.
2639 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2641 Port EXTERNALLY_VISIBLE to Clang 3.2.
2642 * conf_post.h (__has_attribute): New macro.
2643 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2645 2012-12-27 Glenn Morris <rgm@gnu.org>
2647 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2648 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2650 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2652 * fileio.c (file_name_as_directory, directory_file_name):
2653 Accept an additional argument MULTIBYTE to indicate whether the input C
2654 came from a multibyte or a unibyte Lisp string; all callers
2655 adjusted. Don't assume the input string is always multibyte.
2657 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2658 don't ENCODE_FILE them, and return a unibyte string if the input
2660 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2661 don't assume the input strings will always be multibyte. If the
2662 input strings are multibyte, decode strings obtained from C
2665 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2667 * lisp.h (toplevel): Add two notices to the comment about
2668 defining a new Lisp data type.

2672 * alloc.c (valid_lisp_object_p): Adjust comment.
2674 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2676 * keyboard.c (record_asynch_buffer_change): Initialize an event
2677 only if it's really needed.
2678 * frame.h (enum output_method): Remove output_mac member since
2679 it's a leftover from the deleted code.
2680 * frame.c (Fframep): Adjust user here ...
2681 * terminal.c (Fterminal_live_p): ... and here.
2682 * coding.c (Qmac): Now here because it's only used to denote
2683 end-of-line encoding type.
2684 (syms_of_coding): DEFSYM it.
2685 * frame.h (Qmac): Remove duplicated declaration.
2687 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2689 * window.c (select_window_1): Now static, since it's used only here.
2691 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2693 * window.c (window_body_cols): Subtract display margins from the
2694 window body width on TTYs as well. See
2695 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2696 for the original report.
2698 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2700 * xdisp.c (redisplay_window): Remove inner local variable
2701 because the outer shadowed one has the same meaning.
2702 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2704 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2705 (xg_create_tool_bar): Adjust users.
2707 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2709 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2710 * buffer.c (Fget_buffer_create): Use it to set compact field of
2711 struct buffer_text to avoid accessing an uninitialized value
2712 when compact_buffer is called for the first time.
2713 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2714 (Fset_buffer_modified_p): Use buffer_window_count to check
2715 whether the buffer is displayed in some window.
2716 * xdisp.c (message_dolog): Likewise.
2718 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2720 * w32.c (acl_set_file): If setting the file security descriptor
2721 fails, and the new DACL is identical to the existing one, silently
2722 return success. This fixes problems for users backing up their
2723 own files without having the necessary privileges for setting
2724 security descriptors.
2726 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2728 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2729 after WaitForSingleObject returns normally. This expedites reader
2730 thread shutdown when delete_child triggers it.
2731 (reap_subprocess): More accurate commentary for why we call
2732 delete_child only when cp->fd is negative.
2734 * w32.c (sys_close): Do not call delete_child on a subprocess
2735 whose handle is not yet closed. Instead, set its file descriptor
2736 to a negative value, so that reap_subprocess will call
2737 delete_child on that subprocess when its SIGCHLD arrives.
2738 This avoids closing handles used for communications between sys_select
2739 and reader_thread, which doesn't give sys_select a chance to
2740 notice that the process exited and invoke the SIGCHLD handler for
2743 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2745 * nsfns.m (Fns_do_applescript): Run event loop until script has
2746 been executed (Bug#12969).
2747 (ns_run_ascript): Chech as_script for nil, set to nil after
2750 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2752 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2754 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2756 * w32term.c (w32fullscreen_hook): New function.
2757 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2759 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2761 * fileio.c (Finsert_file_contents): Doc fix.
2763 * w32proc.c (new_child, delete_child, find_child_pid): For a
2764 subprocess, consider its slot being in use as long as its process
2765 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2766 slot when a new process is started immediately after killing
2767 another one, without waiting enough time for the first process to
2768 be reaped and resources allocated for it be orderly freed.
2770 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2772 2012-12-21 Chong Yidong <cyd@gnu.org>
2774 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2776 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2778 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2780 * w32.c (get_name_and_id): Always pass NULL as the first argument
2781 of lookup_account_sid. Avoids crashes with UNC file names that

2787 2012-12-21 Chong Yidong <cyd@gnu.org>
2789 * editfns.c (Finsert_char): Since read-char-by-name now signals an

2878 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2880 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2881 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2882 for some of that bug's symptoms can now cause Emacs to abort.
2883 Remove the workaround.
2884 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2885 The bug that caused SIGCHLD to get lost has been fixed, and the
2886 workaround for it can now cause Emacs to abort.
2888 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2890 * sysdep.c (emacs_abort): Bump backtrace size to 40.

2932 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2933 asynchronous subprocess, record the name of the input file name,
2935 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2936 delete the file, record it as pending deletion when the subprocess
2939 2012-12-14 Eli Zaretskii <eliz@gnu.org>

2959 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2961 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2962 try to get accurate owner and group information from NT file
2963 security APIs. This is to make most callers of 'stat' and
2964 'lstat', which don't need that information, much faster.
2966 * dired.c (Ffile_attributes) [WINDOWSNT]:
2967 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2968 owner and group information from 'lstat'.
2970 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2972 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2973 as that confuses set-auto-coding, so insist on the head-read

3002 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3004 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3005 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3006 Remove unnecessary S_ISLNK test, as (contra the comments) this
3007 function can't copy symlinks. Improve quality of error message
3008 when attempting to copy files that are neither regular files nor

3027 * inotify.c (inotify_callback): Generate an Emacs event for every
3028 incoming inotify event.
3030 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3032 * xdisp.c (handle_face_prop): Fix logic of computing
3033 it->start_of_box_run_p.
3034 (append_space_for_newline): If the glyph row is R2L, reset the
3035 iterator's end_of_box_run_p flag before prepending the space glyph.
3036 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3037 iterator's start_of_box_run_p flag before prepending the stretch.

3040 left_box_line_p and right_box_line_p flags of the glyph for R2L
3041 glyph rows. (Bug#13011)

3260 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3261 * lisp.h (xputenv): New decl.
3263 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
3265 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
3267 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3269 * w32.c (unsetenv, sys_putenv): New functions.
3271 2012-12-08 Chong Yidong <cyd@gnu.org>
3273 * editfns.c (Finsert_char): Make the error message more
3274 informative (Bug#12992).
3276 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3278 Simplify get_lim_data.
3279 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3280 Remove USG and vlimit methods; no longer used these days.
3281 Add #error catchall just in case.
3283 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3284 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3285 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3286 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
3287 (deleted_pid_list, Fdelete_process, create_process)
3288 (record_child_status_change, handle_child_signal, deliver_child_signal)
3289 (init_process_emacs, syms_of_process):
3290 Assume SIGCHLD is defined.
3291 (parse_signal): Remove. All uses removed.
3292 (abbr_to_signal): New static function.
3293 (Fsignal_process): Use it to convert signal names to ints.
3294 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
3295 kill (getpgrp (), ...).
3296 (emacs_sigaction_init): Assume SIGCHLD is defined.
3297 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
3298 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
3299 * syssignal.h (EMACS_KILLPG): Remove.
3300 All uses replaced by 'kill' with a negative pid.
3301 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
3302 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
3304 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3306 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3307 This will cause a production Emacs to dump core instead of
3310 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3312 * frame.c (make_frame): Do not set window's buffer to t.
3313 * window.c (Fsplit_window_internal): Likewise. Previously it was
3314 used to indicate that the window is being set up. Now we use
3315 set_window_buffer for all new windows, so the condition in ...
3316 (Fset_window_buffer): ... is always true and can be removed.
3318 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3320 Convenient macro to check whether the buffer is hidden.
3321 * buffer.h (BUFFER_HIDDEN_P): New macro.
3322 * frame.c (make_frame): Use it. Adjust comment.
3323 * buffer.c (candidate_buffer): New function.
3324 (Fother_buffer, other_buffer_safely): Use it.
3326 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3328 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3329 if the child process is still running. Instead, exit the wait
3330 loop and return zero. (Bug#13086)
3332 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3334 * frame.h (x_char_width, x_char_height): Remove prototypes.
3335 * w32term.h (x_char_width, x_char_height): Likewise.
3336 * xfns.c (x_char_width, x_char_height): Remove.
3337 * w32fns.c (x_char_width, x_char_height): Likewise.
3338 * nsfns.c (x_char_width, x_char_height): Likewise.
3339 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
3341 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
3342 * keyboard.c (command_loop_1): Remove prototype.

3345 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
3347 Fix a recently-introduced delete-process race condition.
3348 * callproc.c, process.h (record_kill_process):
3349 New function, containing part of the old call_process_kill.
3350 (call_process_kill): Use it.
3351 This does not change call_process_kill's behavior.
3352 * process.c (Fdelete_process): Use record_kill_process to fix a
3353 race condition that could cause Emacs to lose track of a child.
3355 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3357 Avoid code duplication between prev_frame and next_frame.
3358 * frame.c (candidate_frame): New function. Add comment.
3359 (prev_frame, next_frame): Use it. Adjust comment.
3361 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3363 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3364 fails, signal an error instead of continuing with an empty
3366 Encode expanded temp file pattern before passing it to mkstemp or
3369 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3370 Encode the file name before passing it to dostounix_filename, in
3371 case it will downcase it (under w32-downcase-file-names).
3374 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3376 Minor call-process cleanups.
3377 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3378 at the same time as other platforms, to simplify analysis.
3379 No need for fd0_volatile since we have synch_process_fd.
3380 Avoid needless emacs_close; arg is always negative.
3382 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3384 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3387 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3389 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3390 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3391 and mouse_face_hidden members to a bitfields.
3392 * frame.h (struct frame): Remove set-but-not-used space_width member.
3393 (FRAME_SPACE_WIDTH): Remove.
3394 * nsterm.m, w32term.c, xterm.c: Adjust users.
3395 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3396 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3397 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3398 members to a bitfields.
3400 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3402 Don't let call-process be a zombie factory (Bug#12980).
3403 Fixing this bug required some cleanup of the signal-handling code.
3404 As a side effect, this change also fixes a longstanding rare race
3405 condition whereby Emacs could mistakenly kill unrelated processes,
3406 and it fixes a bug where a second C-g does not kill a recalcitrant
3407 synchronous process in GNU/Linux and similar platforms.
3408 The patch should also fix the last vestiges of Bug#9488,
3409 a bug which has mostly been fixed on the trunk by other changes.
3410 * callproc.c, process.h (synch_process_alive, synch_process_death)
3411 (synch_process_termsig, sync_process_retcode):
3412 Remove. All uses removed, to simplify analysis and so that
3413 less consing is done inside critical sections.
3414 * callproc.c (call_process_exited): Remove. All uses replaced
3415 with !synch_process_pid.
3416 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3417 These take the role of what used to be in unwind-protect arg.
3419 (block_child_signal, unblock_child_signal):
3420 New functions, to avoid races that could kill innocent-victim processes.
3421 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3422 (call_process_kill): Record killed processes as deleted, so that
3423 zombies do not clutter up the system. Do this inside a critical
3424 section, to avoid a race that would allow the clutter.
3425 (call_process_cleanup): Fix code so that the second C-g works again
3426 on common platforms such as GNU/Linux.
3427 (Fcall_process): Create the child process in a critical section,
3428 to fix a race condition. If creating an asynchronous process,
3429 record it as deleted so that zombies do not clutter up the system.
3430 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3431 light of these changes. Omit unnecessary call to emacs_close
3432 before failure, as the unwind-protect code does that.
3433 * callproc.c (call_process_cleanup):
3434 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3435 * process.c (record_deleted_pid): New function, containing
3436 code refactored out of Fdelete_process.
3437 (Fdelete_process): Use it.
3438 (process_status_retrieved): Remove. All callers changed to use
3439 child_status_change.
3440 (record_child_status_change): Remove, folding its contents into ...
3441 (handle_child_signal): ... this signal handler. Now, this
3442 function is purely a handler for SIGCHLD, and is not called after
3443 a synchronous waitpid returns; the synchronous code is moved to
3444 wait_for_termination. There is no need to worry about reaping
3445 more than one child now.
3446 * sysdep.c (get_child_status, child_status_changed): New functions.
3447 (wait_for_termination): Now takes int * status and bool
3448 interruptible arguments, too. Do not record child status change;
3449 that's now the caller's responsibility. All callers changed.
3450 Reimplement in terms of get_child_status.
3451 (wait_for_termination_1, interruptible_wait_for_termination):
3452 Remove. All callers changed to use wait_for_termination.
3453 * syswait.h: Include <stdbool.h>, for bool.
3454 (record_child_status_change, interruptible_wait_for_termination):
3456 (record_deleted_pid, child_status_changed): New decls.
3457 (wait_for_termination): Adjust to API changes noted above.
3459 * bytecode.c, lisp.h (Qbytecode): Remove.
3460 No longer needed after 2012-11-20 interactive-p changes.
3462 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3464 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3465 the scroll margin, move point outside the margin. (Bug#13055)
3467 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3469 * gtkutil.c (my_log_handler): New function.
3470 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3472 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3474 * lisp.h (modify_region): Rename to...
3475 (modify_region_1): ...new prototype.
3476 * textprop.c (modify_region): Now static. Adjust users.
3477 * insdel.c (modify_region): Rename to...
3478 (modify_region_1): ...new function to work with current buffer.
3479 Adjust comment and users. Use true and false for booleans.
3481 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3483 * alloc.c (free_save_value): New function.
3484 (safe_alloca_unwind): Use it.
3485 * lisp.h (free_save_value): New prototype.
3486 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3488 (save_excursion_restore): Adjust to match saved data structure.
3489 Use free_save_value to offload some work from GC. Drop obsolete
3492 2012-12-03 Chong Yidong <cyd@gnu.org>
3494 * fileio.c (Vauto_save_list_file_name): Doc fix.
3496 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3498 * w32fns.c: Remove prototype of atof.
3499 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3501 (file_dialog_callback): Make it UINT_PTR.
3503 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3506 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3507 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3510 2012-12-03 Glenn Morris <rgm@gnu.org>
3512 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3514 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3516 Fix xpalloc confusion after memory is exhausted.
3517 * alloc.c (xpalloc): Comment fix.
3518 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3519 and signals an error, do not clear charset_table_size, as
3520 charset_table is still valid.
3521 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3523 Use execve to avoid need to munge environ (Bug#13054).
3524 * callproc.c (Fcall_process):
3525 * process.c (create_process):
3526 Don't save and restore environ; no longer needed.
3527 * callproc.c (child_setup):
3528 Use execve, not execvp, to preserve environ.
3530 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3532 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3534 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3536 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3537 display for sliced images (Bug#10500).
3539 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3541 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3543 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3544 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3546 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3548 * xdisp.c (window_outdated): Remove eassert since it hits
3549 some suspicious corner cases (see Bug#13007 and Bug#13012).
3550 (mode_line_update_needed): New function.
3551 (redisplay_internal, redisplay_window): Use it.
3552 (ensure_selected_frame): New function.
3553 (redisplay_internal, unwind_redisplay): Use it.
3554 (redisplay_internal): Move comment about buffer_shared...
3555 (buffer_shared_and_changed): ...near to its real use.
3557 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3559 * callproc.c (Fcall_process): Don't misreport vfork failure.
3561 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3563 * callproc.c (Fcall_process): Fix vfork portability problems.
3564 Do not assume that fd[0], count, filefd, and save_environ survive
3565 vfork. Fix bug whereby wrong errno value could be reported for
3566 pipe failure. Some minor cleanups, too, as follows. Move buf and
3567 bufsize to the context where they're needed. Change new_argv to
3568 be of type char **, as this is more convenient and avoids casts.
3569 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3570 Now local constants, not macros.
3572 2012-11-18 Kenichi Handa <handa@gnu.org>
3574 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3575 for the variable "f".
3577 2012-11-13 Kenichi Handa <handa@gnu.org>
3579 * font.c (font_unparse_xlfd): Exclude special characters from the
3580 generating XLFD name.
3582 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3584 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

3595 * lread.c (readbyte_from_file): Assume EINTR is defined.
3596 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3597 Assume EIO and EAGAIN are defined.
3598 * unexcoff.c (write_segment): Assume EFAULT is defined.
3600 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3602 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3605 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3606 highlighting on the frame was cleared. Prevents assertion
3607 violations when repeatedly clicking on the "Top" link of the
3608 "bread-crumbs" in Info buffers.
3610 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
3612 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.

3617 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3618 were always defined.
3620 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3622 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3623 between bpos_covered and bpos_max. This fixes cursor display when
3624 several display strings follow each other.
3626 * .gdbinit (pgx): If the glyph's object is a string, display the
3627 pointer to string data, rather than the value of the string object
3628 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3630 * indent.c (Fvertical_motion): If the starting position is covered
3631 by a display string, return to one position before that, to avoid
3632 overshooting it inside move_it_to. (Bug#12930)
3634 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3636 * frame.h (struct frame): Remove display_preempted member

3639 * w32menu.c (pending_menu_activation): Remove since not
3641 (set_frame_menubar): Adjust user.
3642 * w32term.h (struct x_output): Drop outdated #if 0 code.
3643 (struct w32_output): Use bitfields for explicit_parent,
3644 asked_for_visible and menubar_active members.
3645 Drop unused pending_menu_activation member.
3646 * xterm.h (struct x_output): Drop outdated #if 0 code.
3647 Use bitfields for explicit_parent, asked_for_visible,
3648 has_been_visible and net_wm_state_hidden_seen members.
3650 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3652 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3653 of a literal "/". (Bug#12955)
3654 (gl-stamp): Invoke fc.exe directly, not through cmd.
3656 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

3659 * dired.c: Assume HAVE_DIRENT_H.
3660 (NAMLEN): Remove, replacing with ...
3661 (dirent_namelen): New function. All uses changed. Use the GNU macro
3662 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3663 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3664 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3665 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3667 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3668 * ndir.h: Rename to ../nt/inc/dirent.h.
3669 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3670 Do not include <dirent.h>; no longer needed.
3671 * w32.c: Include <dirent.h> rather than "ndir.h".
3673 2012-11-23 Chong Yidong <cyd@gnu.org>
3675 * xftfont.c (xftfont_open): Remove duplicate assignment.
3677 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3679 * alloc.c (Fgarbage_collect): Unblock input after clearing
3680 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3681 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3682 * msdos.c (IT_frame_up_to_date): Use it here...
3683 * w32term.c (w32_frame_up_to_date): ...here...
3684 * xterm.c (XTframe_up_to_date): ...and here...
3685 * nsterm.m (ns_frame_up_to_date): ...but not here.
3686 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3688 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3689 Do not check whether GC is in progress.
3691 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3693 * xdisp.c (window_buffer_changed): New function.
3694 (update_menu_bar, update_tool_bar): Use it to
3695 simplify large 'if' statements.
3696 (redisplay_internal): Generalize commonly used
3697 'tail' and 'frame' local variables.
3699 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3701 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3702 with Windows system header.
3704 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3706 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3707 * alloc.c: Assume unistd.h exists.

3711 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3712 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3713 * w32.h (getcwd): Remove decl.

3717 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3718 Make it set selected_window as well.
3719 (update_tool_bar): Use it.
3721 2012-11-21 Ken Brown <kbrown@cornell.edu>
3723 * emacs.c (main): Set the G_SLICE environment variable for all
3724 Cygwin builds, not just GTK builds. See
3725 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3727 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3729 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3730 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3731 Define for the MSVC compiler.
3733 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3735 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3736 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3737 dostounix_filename. Prevents crashes down the road, because
3738 dostounix_filename assumes it gets a unibyte string.
3739 Reported by Michel de Ruiter <michel@sentient.nl>, see
3740 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3742 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3744 Conflate Qnil and Qunbound for `symbol-function'.

3746 * lread.c (init_obarray): Set `function' fields to Qnil.
3747 * eval.c (Fcommandp): Ignore Qunbound.
3748 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3749 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3750 Test NILP rather than Qunbound.
3751 (Ffmakunbound): Set to Qnil.
3752 (Fsymbol_function): Never signal an error.
3753 (Finteractive_form): Ignore Qunbound.
3755 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3757 * eval.c (interactive_p): Remove no-longer-used decl.
3759 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3761 * xdisp.c (buffer_shared): Adjust comment.
3762 (buffer_shared_and_changed): New function.
3763 (prepare_menu_bars, redisplay_internal): Use it to
3764 decide whether all windows or frames should be updated.
3765 (window_outdated): New function.
3766 (text_outside_line_unchanged_p, redisplay_window): Use it.
3767 (redisplay_internal): Likewise. Fix indentation.
3769 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3771 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3772 (syms_of_eval): Remove corresponding defsubr.
3773 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3775 2012-11-19 Daniel Colascione <dancol@dancol.org>
3777 * w32fns.c (Fx_file_dialog):
3778 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3779 cygwin_convert_file_name*.
3781 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3782 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3784 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3786 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3788 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3790 * w32select.c: Include w32common.h before w32term.h, so that
3791 windows.h gets included before w32term.h uses some of its
3792 features, see below.
3794 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3796 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3798 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3800 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3802 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3803 (ns_select): Return at once if events are held (Bug#12834).
3805 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3807 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3808 Needed following 2012-10-20 change. (Bug#12902)
3810 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3812 * w32proc.c (waitpid): Remove unused label get_result.
3814 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3816 * makefile.w32-in (SYSWAIT_H): New macro.
3817 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3818 ($(BLD)/sysdep.$(O)): Update dependencies.
3820 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3822 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3823 * callproc.c (relocate_fd): Assume F_DUPFD.
3824 * emacs.c, term.c (O_RDWR): Remove.
3825 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3826 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3827 * nsterm.m: Assume <fcntl.h> exists.
3828 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3829 (create_pty, Fmake_network_process, server_accept_connection)
3830 (wait_reading_process_output, init_process_emacs):
3832 (wait_reading_process_output): Put in a special case for WINDOWSNT
3833 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3834 It's not clear this is needed, but it's a more-conservative change.
3835 (create_process): Assume FD_CLOEXEC.
3836 (create_process, create_pty): Assume O_NOCTTY.
3837 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3838 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3839 Omit if not DOS_NT, since F_GETFL is not defined there.
3840 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3841 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3843 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3844 lack it, since gnulib guarantees this.
3845 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3847 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3849 * w32.c (faccessat): Pretend that directories have the execute bit
3850 set. Emacs expects that, e.g., in files.el:cd-absolute.
3852 * w32proc.c (create_child): Don't clip the PID of the child
3853 process to fit into an Emacs integer, as this is no longer a
3855 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3856 reaping only the process specified by PID argument, if that is
3857 positive. Use PID instead of dead_child to know which process to
3858 reap. Wait for the child to die only if WNOHANG is not in
3860 (sys_select): Don't set dead_child.
3862 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3863 as it is no longer needed.
3865 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3867 (record_child_status_change): Remove the setting of
3868 record_at_most_one_child for the !WNOHANG case.
3870 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3872 Fix problems in ns port found by static checking.
3873 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3874 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3875 not to process group.
3876 (ns_select): Use emacs_write, not write, as that's more robust
3877 in the presence of signals.
3878 (fd_handler:): Check for read errors.
3880 2012-11-16 Glenn Morris <rgm@gnu.org>
3882 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3884 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3886 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3888 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3890 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3891 use the same value of thread handle.
3892 (start_timer_thread): If the timer thread exited (due to error),
3893 clean up by closing the two handles it used. Duplicate the caller
3894 thread's handle here, so it gets duplicated only once, when
3895 launching the timer thread. Set priority of the timer thread, not
3897 (getitimer): Don't duplicate the caller thread's handle here.
3900 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3902 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3905 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3907 Remove no-longer-used pty_max_bytes variable.
3908 * process.c (pty_max_bytes): Remove; unused.
3909 (send_process): Do not set it.
3911 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3913 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3914 Update dependencies.
3916 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3918 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3919 This follows up on the 2012-09-29 patch that removed indirection
3920 for the 'function' field. Reported by Sergey Vinokurov in
3921 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3923 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3925 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3926 different name, as the MS runtime does not have such a function,
3927 and probably never will.) All callers changed. Ignore DIRFD
3928 value if PATH is an absolute file name, to match Posix spec
3929 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3932 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3934 * xdisp.c (echo_area_display, redisplay_internal):
3935 Omit redundant check whether frame_garbaged is set.
3937 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3939 Use faccessat, not access, when checking file permissions (Bug#12632).
3940 This fixes a bug that has been present in Emacs since its creation.
3941 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3942 which must set some sort of record. (Torek's bug report was against
3943 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3944 same common flaw.) See Torek's Usenet posting
3945 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3946 Posted: Fri Apr 8 14:18:56 1983.
3947 * Makefile.in (LIB_EACCESS): New macro.
3949 * callproc.c (init_callproc):
3950 * charset.c (init_charset):
3951 * fileio.c (check_existing, check_executable, check_writable)
3953 * lread.c (openp, load_path_check):
3954 * process.c (allocate_pty):
3956 Use effective UID when checking permissions, not real UID.
3957 * callproc.c (init_callproc):
3958 * charset.c (init_charset):
3959 * lread.c (load_path_check, init_lread):
3960 Test whether directories are accessible, not merely whether they exist.
3961 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3962 * fileio.c (check_existing, check_executable, check_writable)
3964 Use symbolic names instead of integers for the flags, as they're
3966 (check_writable): New arg AMODE. All uses changed.
3967 Set errno on failure.
3968 (Ffile_readable_p): Use faccessat, not stat + open + close.
3969 (Ffile_writable_p): No need to call check_existing + check_writable.
3970 Just call check_writable and then look at errno. This saves a syscall.
3971 dir should never be nil; replace an unnecessary runtime check
3972 with an eassert. When checking the parent directory of a nonexistent
3973 file, check that the directory is searchable as well as writable, as
3974 we can't create files in unsearchable directories.
3975 (file_directory_p): New function, which uses 'stat' on most platforms
3976 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3977 (Ffile_directory_p, Fset_file_times): Use it.
3978 (file_accessible_directory_p): New function, which uses a single
3979 syscall for efficiency.
3980 (Ffile_accessible_directory_p): Use it.
3981 * xrdb.c (file_p): Use file_directory_p.
3982 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3983 * lread.c (openp): When opening a file, use fstat rather than
3984 stat, as that avoids a permissions race. When not opening a file,
3985 use file_directory_p rather than stat.
3986 (dir_warning): First arg is now a usage string, not a format.
3987 Use errno. All uses changed.
3988 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3989 that merely introduced a race.
3990 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3991 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3992 and similarly for the other O_* flags.
3993 * w32.c (sys_faccessat): Rename from sys_access and switch to
3994 faccessat's API. All uses changed.
3995 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3996 (magic_db): Rename from magic_file_p.
3997 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3998 char *, so that we don't have to test for file existence
3999 separately from opening the file for reading. This removes a race
4000 fixes a permission-checking problem, and simplifies the code.
4002 (file_p): Remove; no longer needed.
4004 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4006 Omit glyphs initialization at startup.
4007 * dispnew.c (glyphs_initialized_initially_p): Remove.
4008 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4009 (Fredraw_frame): Move actual code from here...
4010 (redraw_frame): ...to here. Add eassert. Adjust comment.
4011 (Fredraw_display): Use redraw_frame.
4012 * xdisp.c (clear_garbaged_frames): Likewise.
4014 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4016 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4017 passed to pint2str and pint2hrstr to be at most the size of the
4018 frame's decode_mode_spec_buffer. This avoids crashes with very
4019 large values of FIELD_WIDTH argument to decode_mode_spec.
4022 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4024 Fix a race with verify-visited-file-modtime (Bug#12863).
4025 Since at least 1991 Emacs has ignored an mtime difference of no
4026 more than one second, but my guess is that this was to work around
4027 file system bugs that were fixed long ago. Since the race is
4028 causing problems now, let's remove that code.
4029 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4030 whose time stamp is off by no more than a second. Insist that the
4031 file time stamps match exactly.
4033 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4035 * frame.h (struct frame): Convert external_tool_bar member to
4036 1-bit unsigned bitfield.
4037 * termhooks.h (struct terminal): Remove mouse_moved member since
4038 all users are long dead. Adjust comment on mouse_position_hook.
4040 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4042 Simplify by using FOR_EACH_FRAME here and there.
4043 * frame.c (next_frame, prev_frame, other_visible_frames)
4044 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4045 * w32term.c (x_window_to_scroll_bar): Likewise.
4046 * window.c (window_list): Likewise.
4047 * xdisp.c (x_consider_frame_title): Likewise.
4048 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4049 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4050 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4051 * xmenu.c (menubar_id_to_frame): Likewise.
4052 * xselect.c (frame_for_x_selection): Likewise.
4053 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4054 (x_window_to_menu_bar): Likewise.
4055 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4057 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4059 * data.c (Qdefalias_fset_function): Now static.
4061 Another tweak to vectorlike_header change.
4062 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4063 Remove, and replace all uses with ...
4064 (next_in_free_list, set_next_in_free_list):
4065 New functions, which respect C's aliasing rules better.
4067 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4069 * window.c (list4i): Rename from 'quad'. All uses changed.
4070 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4072 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4074 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4075 warning about mixing declarations and code in ISO C90.
4077 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4079 * window.c (Fsplit_window_internal): Set combination limit of
4080 new parent window to t iff Vwindow_combination_limit is t;
4081 fixing a regression introduced with the change from 2012-09-22.
4082 (Fset_window_combination_limit): Fix doc-string.
4084 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4086 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4087 amount when the scroll margins are too large. When scrolling
4088 backwards in the buffer, give up if cannot reach point or the
4089 scroll margin within a reasonable number of screen lines.
4090 Fixes point position in window under scroll-up/down-aggressively when
4091 point is positioned many lines beyond the window top/bottom.
4094 * ralloc.c (relinquish): If real_morecore fails to return memory
4095 to the system, don't crash; instead, leave the last heap
4096 unchanged and return. (Bug#12774)
4098 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4100 * lisp.h (AUTOLOADP): New macro.
4101 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
4102 * data.c (Ffset): Remove special ad-advice-info handling.
4103 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
4105 (Finteractive_form): Simplify.
4106 (Fquo): Don't insist on having at least 2 arguments.
4107 (Qdefalias_fset_function): New var.
4109 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4111 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4113 * nsfont.m (Qcondensed, Qexpanded): New variables.
4114 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
4115 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4117 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4119 Fix recently introduced crash on MS-Windows (Bug#12839).
4120 * w32term.h (struct scroll_bar): Use convenient header.
4121 (SCROLL_BAR_VEC_SIZE): Remove.
4122 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4124 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4126 Tweak last vectorlike_header change.
4127 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4128 vectorlike object on the free list. This is introduced to avoid
4129 some (but not all) pointer casting and aliasing problems, see
4130 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4131 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
4133 (xvectype, xvecsize): Use them to examine Lisp_Object values.
4135 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4137 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4138 been removed, so remove them here also.
4140 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4142 * doc.c (Fdocumentation): Handle new property
4143 dynamic-docstring-function to replace the old ad-advice-info.
4145 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4147 * fns.c (Qeql, hashtest_eq): Now static.
4149 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4151 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4152 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4153 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
4154 * buffer.c (compare_overlays): Use XLI rather than XHASH.
4156 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
4158 Use same hash function for hashfn_profiler as for hash_string etc.
4159 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4160 * lisp.h (sxhash_combine): New inline function, with the contents
4161 of the old SXHASH_COMBINE.
4162 * profiler.c (hashfn_profiler): Use it, instead of having a
4163 special hash function containing a comparison that always yields 1.
4165 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>

4172 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4174 * image.c (xpm_make_color_table_h): Fix compiler error because
4175 make_hash_table changed.

4179 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4181 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4183 Use ad-hoc comparison function for the profiler's hash-tables.
4184 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4185 (make_log): Use them.
4186 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4187 call Fequal any more.

4196 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4197 (hash_lookup, hash_remove_from_table): Move assertion checking of
4198 hashfn result here. Check hash-equality before calling cmpfn.

4208 2012-11-08 Eli Zaretskii <eliz@gnu.org>
4210 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4211 value of w32-scroll-lock-modifier is neither nil nor one of the
4212 known key modifiers. (Bug#12806)
4214 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4216 Shrink struct vectorlike_header to the only size field.
4217 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4219 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and

4221 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4222 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4223 information from the vector header. Adjust comment.

4238 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4239 (large_vectors): Change type to struct large_vector.
4240 (allocate_vector_from_block): Simplify.
4241 (PSEUDOVECTOR_NBYTES): Replace with...

4244 (allocate_vectorlike): Likewise.
4245 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4246 Add easserts. Adjust XSETPVECTYPESIZE usage.
4247 (allocate_buffer): Use BUFFER_PVEC_INIT.
4248 (live_vector_p): Adjust to match large vector.
4249 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4250 * buffer.h (struct buffer): Add next member.
4251 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4253 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

4261 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4263 * keyboard.c (event_to_kboard): Do not dereference
4264 frame_or_window field of SELECTION_REQUEST_EVENT
4265 and SELECTION_CLEAR_EVENT events (Bug#12814).
4266 * xterm.h (struct selection_input_event): Adjust comment.
4268 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4270 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4271 such as Scroll Lock, if the respective keys are treated as
4272 function keys, not as modifiers. This avoids destroying non-ASCII
4273 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4275 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4277 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4279 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4281 Restore some duplicate definitions (Bug#12814).
4282 This undoes part of the 2012-11-03 changes. Some people build
4283 with plain -g rather than with -g3, and they need the duplicate
4284 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4285 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4286 Define as macros, as well as as enums or as constants.
4288 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4290 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4291 to keypad keys (Bug#12816).
4293 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4295 Minor adjustments of recently-changed frame functions.
4296 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4297 known to be a frame (we're in the FRAMEP branch).
4298 * lisp.h (Qframep): Remove decl. frame.h declares this.
4299 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4300 since they're meant for Lisp fixnum values.
4302 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4304 * window.c (Fwindow_combination_limit): Revert to the only
4305 required argument and adjust docstring as suggested in
4306 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4307 by Martin Rudalics <rudalics@gmx.at>.
4309 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4311 Widely used frame validity and checking functions.
4312 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.

4325 * buffer.c (Fother_buffer): Use decode_any_frame.
4326 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4327 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4328 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4329 (Fclose_font, Ffont_info): Use decode_live_frame.
4330 * fontset.c (check_fontset_name): Likewise.

4332 * w32fns.c (check_x_frame): Likewise.
4333 * window.c (Fminibuffer_window, Fwindow_at)
4334 (Fcurrent_window_configuration): Likewise.

4338 * xfaces.c (frame_or_selected_frame): Remove.
4339 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4340 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4341 (Fframe_face_alist): Use decode_live_frame.
4342 * xfns.c (check_x_frame): Likewise.
4344 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4346 * window.c (quad): New function.
4347 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4348 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4349 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4350 (Fwindow_line_height): Use it.
4351 (Fwindow_fringes): Use list3.
4352 (Fwindow_scroll_bars): Use list4.
4353 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4354 (Fwindow_combination_limit): Allow zero number of arguments.
4356 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4358 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4360 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4361 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4362 file descriptor 2 for standard error. (Bug#12805)
4364 2012-11-05 Chong Yidong <cyd@gnu.org>
4366 * process.c (wait_reading_process_output): Revert previous change.
4368 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4370 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4371 This removes code that has been obsolete since around 1990.
4372 * callproc.c (Fcall_process):
4374 * process.c (create_process):
4375 * term.c (dissociate_if_controlling_tty):
4376 Assume setsid exists.
4377 * callproc.c (child_setup): Assume setpgid exists and behaves as
4378 per POSIX.1-1988 or later.
4379 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4380 * emacs.c (shut_down_emacs):
4381 * sysdep.c (sys_suspend, init_foreground_group):
4382 Assume getpgrp behaves as per POSIX.1-1998 or later.
4383 * msdos.c (setpgrp): Remove.
4384 (tcgetpgrp, setpgid, setsid): New functions.
4385 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4386 * term.c (no_controlling_tty): Remove; unused.
4387 * w32proc.c (setpgrp): Remove.
4388 (setsid, tcgetpgrp): New functions.
4390 Simplify by assuming __fpending.
4391 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4392 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4393 Do not assume that __fpending's result fits in int.
4395 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4397 Remove EMACS_OUTQSIZE+sleep hack.
4398 * dispnew.c (update_frame_1): Remove hack for terminals slower
4399 than 2400 bps, which throttled Emacs by having it sleep.
4400 This code hasn't worked since at least 2007, when the multi-tty stuff
4401 was added, and anyway those old terminals are long dead.
4402 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4403 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4405 Fix data-loss with --version (Bug#9574).
4406 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4407 as we can't assume that emacs_strerror is initialized, and strerror
4408 is good enough here.
4409 (main): Invoke atexit earlier, to catch earlier instances of
4410 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4412 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4414 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4415 (keyDown): Remap keypad keys to X11 virtual key codes.
4417 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4419 Fix data-loss with --batch (Bug#9574).
4420 * emacs.c: Include <close-stream.h>.
4421 (close_output_streams): New function.
4422 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4423 and handles errors appropriately.
4424 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4427 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4428 The symptom is a diagnostic "GLib-WARNING **: In call to
4429 g_spawn_sync(), exit status of a child process was requested but
4430 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4431 waitpid(), so exit status can't be returned." The diagnostic
4432 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4433 The real bug is a race condition between Emacs and glib: Emacs
4434 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4435 so that glib can't find it. Work around the bug by invoking
4436 waitpid only on subprocesses that Emacs itself creates.
4437 * process.c (create_process, record_child_status_change):
4438 Don't use special value -1 in pid field, as the caller now must
4439 know the pid rather than having the callee infer it.
4440 The inference was sometimes incorrect anyway, due to another race.
4441 (create_process): Set new 'alive' member if child is created.
4442 (process_status_retrieved): New function.
4443 (record_child_status_change): Use it.
4444 Accept negative 1st argument, which means to wait for the
4445 processes that Emacs already knows about. Move special-case code
4446 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4447 processes that have already been waited for, by testing and
4448 clearing new 'alive' member.
4449 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4450 now does this internally.
4451 (handle_child_signal): Let record_child_status_change do all
4452 the work, since we do not want to reap all exited child processes,
4453 only the child processes that Emacs itself created.
4454 * process.h (Lisp_Process): New boolean member 'alive'.
4456 Omit duplicate definitions no longer needed with gcc -g3.
4457 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4458 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4459 Define only as macros. There's no longer any need to also define
4460 these symbols as enums or as constants, since we now assume
4461 gcc -g3 when debugging.
4463 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4465 * lisp.mk: Adjust comments to the fact that term/internal is now
4466 loaded from loadup.el.
4468 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4469 (msdos_fatal_signal): New function.
4470 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4473 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4474 for GCC versions before 4.
4475 (emacs_raise): Define to call msdos_fatal_signal.
4477 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4478 iterator when starting in the middle of a display or overlay
4481 2012-11-03 Chong Yidong <cyd@gnu.org>
4483 * process.c (wait_reading_process_output): Clean up the last
4486 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4488 * process.c (wait_reading_process_output): Avoid a race condition
4489 with SIGIO delivery (Bug#11536).
4491 2012-11-03 Chong Yidong <cyd@gnu.org>
4493 * buffer.c (cursor_type): Untabify docstring.
4495 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4497 * frame.h (struct frame): Drop can_have_scroll_bars member
4498 which is meaningless for a long time. Adjust comments.
4499 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4500 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4502 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4504 * window.c (decode_next_window_args): Update window arg after
4505 calling decode_live_window and so fix crash reported at
4506 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4507 by Juanma Barranquero <lekktu@gmail.com>.
4508 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4509 * font.c (Ffont_at): Likewise.
4511 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4513 * widget.c (resize_cb): New function.
4514 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4515 (EmacsFrameResize): Check if all is up to date before changing frame
4518 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4520 Implement backtrace output for fatal errors on MS-Windows.
4521 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4522 (BACKTRACE_LIMIT_MAX): New macro.
4523 (w32_backtrace): New function.
4524 (emacs_abort): Use w32_backtrace when the user chooses not to
4525 attach a debugger. Update the text of the abort dialog.
4527 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4529 Window-related stuff cleanup here and there.
4530 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4531 Use decode_any_window.
4532 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4533 * xdisp.c (Fformat_mode_line): Likewise.

4539 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4540 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4543 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4545 Remove pad from struct input_event.
4546 * termhooks.h (struct input_event): Remove padding field.
4548 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4549 member is never cons for a long time. Adjust comment.
4550 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4551 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4552 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4553 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4555 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4557 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4559 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4561 Fix crash when using Emacs as commit editor for git (Bug#12697).
4562 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4563 and it is configured in conf_post.h.
4564 (Fcall_process): Don't invoke both setsid and setpgid; the former
4565 is enough, if it exists.
4566 * callproc.c (Fcall_process, child_setup):
4567 * process.c (create_process): Use setpgid.
4568 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4570 * dispnew.c (init_display): Initialize the foreground group
4571 if we are running a tty display.
4572 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4573 * lisp.h (init_foreground_group): New decl.
4574 * sysdep.c (inherited_pgroup): New static var.
4575 (init_foreground_group, tcsetpgrp_without_stopping)
4576 (narrow_foreground_group, widen_foreground_group): New functions.
4577 (init_sys_modes): Narrow foreground group.
4578 (reset_sys_modes): Widen foreground group.

4584 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4586 * minibuf.c (read_minibuf): Restore current buffer since
4587 choose_minibuf_frame calling Fset_frame_selected_window may
4588 change it (Bug#12766).
4590 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4592 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).

4601 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4602 In preparation for fixing bug#12739, move these functions from
4605 * coding.h, coding.c: ... to here, and compile them only when
4606 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4607 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4609 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4611 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4612 (timer_loop, getitimer, setitimer): Use it instead of
4613 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4615 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4618 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4620 * nsterm.m (NO_APPDEFINED_DATA): New define.
4621 (last_appdefined_event_data): New variable
4622 (last_appdefined_event): Remove.
4623 (ns_select): Initialize t from last_appdefined_event_data instead
4624 of [last_appdefined_event data1].
4625 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4626 remove last_appdefined_event (Bug#12698).
4628 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4630 * frame.c (x_set_font): Catch internal error.
4632 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4634 Avoid overflow in w32 implementation of interval timers.
4635 When possible, for ITIMER_PROF count only times the main thread
4637 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4638 'volatile ULONGLONG' types. All the other data which was
4639 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4640 (GetThreadTimes_Proc): New typedef.
4641 (w32_get_timer_time): New function, returns a suitable time value
4643 (timer_loop): Enter critical section when accessing ULONGLONG
4644 values of the itimer_data struct, as these accesses are no longer
4645 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4646 Remove unused variable.
4647 (init_timers): Initialize s_pfn_Get_Thread_Times.
4648 (start_timer_thread): Don't assign itimer->caller_thread here.
4649 (getitimer): Assign itimer->caller_thread here.
4650 (setitimer): Always call getitimer to get the value of ticks_now.

4655 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4656 mouse movement events if the menu bar is active. This avoids
4657 producing a busy "hour-glass" cursor by Windows if the mouse
4658 pointer is positioned over a tooltip shown for some menu item.
4660 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4662 Don't assume process IDs fit in int.
4663 * emacs.c (shut_down_emacs) [!DOS_NT]:
4664 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4665 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4666 Use pid_t, not int, to store process IDs, as 'int'
4667 is not wide enough on a few platforms (e.g., AIX and IRIX).
4669 2012-10-23 Kenichi Handa <handa@gnu.org>
4671 The following change is to make face-font-rescale-alist work
4672 correctly for non-ASCII fonts.
4674 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4675 (font_open_for_lface): Handle Vface_font_rescale_alist.
4677 2012-10-23 Chong Yidong <cyd@gnu.org>
4679 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4681 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

4690 2012-10-21 Glenn Morris <rgm@gnu.org>
4692 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4694 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4696 Port to OpenBSD 5.1.
4697 * frame.c (Fmouse_position, Fmouse_pixel_position):
4698 * xdisp.c (produce_stretch_glyph):
4699 Declare local vars only when they're needed.
4700 This is clearer and avoids a warning on OpenBSD about unused vars.

4702 This is safer, and avoids OpenBSD warnings about unused vars.
4703 * keyboard.c (record_menu_key): Remove unnecessary decl.
4704 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4705 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4706 as our definition clashes with OpenBSD's.
4707 * xfaces.c (load_face_colors, check_lface_attrs)
4708 (get_lface_attributes_no_remap, get_lface_attributes)
4709 (lface_fully_specified_p, x_supports_face_attributes_p)
4710 (tty_supports_face_attributes_p, face_fontset, realize_face)
4711 (realize_x_face, realize_tty_face):
4712 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4713 merely Lisp_Object *. This is more informative and avoids
4714 a warning on OpenBSD about accessing beyond an object's size.
4716 2012-10-20 Chong Yidong <cyd@gnu.org>
4718 * lread.c (Fload): Doc fix (Bug#12592).

4744 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4745 (staticpro): If we run out of staticpro slots, die with an
4746 informative error instead of just calling emacs_abort.
4748 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4750 Fix two flaws reported by Dmitry Antipov.

5005 since unsigned is guaranteed to have that behavior and signed is not.

5007 (get_input_pending): Remove first argument, since it was always
5008 the same pointer-to-int (now pointer-to-boolean) &input_pending,

5010 input_pending. All callers changed.
5011 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5012 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

5055 match what GetLastError returns. Explain why the function is
5058 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5059 'is_tooltip_frame', to avoid confusion with its global namesake.
5061 2012-10-08 Daniel Colascione <dancol@dancol.org>
5063 * xdisp.c (start_hourglass): Call w32_note_current_window when
5064 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5065 build that caused Emacs to display the hourglass cursor forever.
5067 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5068 which is broken under remote desktop, calculate the number of
5069 colors available for a display based on the display's number of
5070 planes and number of bits per pixel per plane. (bug#10397).
5072 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5074 * nsfont.m (Vfonts_in_cache): New variable.

5081 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5083 (FONT_H): Define after FRAME_H.
5084 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5085 Update dependencies.
5087 * w32term.c: Remove leftover declaration of keyboard_codepage.
5089 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5091 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5092 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5093 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5094 (GLOBAL_SOURCES): Add cygw32.c.
5095 ($(BLD)/unexw32.$(O)):
5097 ($(BLD)/w32console.$(O)):
5098 ($(BLD)/w32fns.$(O)):
5099 ($(BLD)/w32heap.$(O)):
5100 ($(BLD)/w32menu.$(O)):
5101 ($(BLD)/w32proc.$(O)): Add w32common.h.
5103 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5105 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5107 2012-10-08 Daniel Colascione <dancol@dancol.org>
5109 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5110 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5111 accidental message numbering hole. Change other messages to
5114 * w32select.h (HAVE_W32SELECT): Remove.
5116 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5117 w32common.h instead of w32heap.h.
5119 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5120 (get_allocation_unit, get_processor_type, get_w32_major_version)
5121 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5122 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5123 (OS_NT, os_subtype, cache_system_info): Move declarations to
5126 * w32heap.c: Include w32common.h.
5127 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5128 (w32_minor_version, w32_build_number, w32_subtype):
5129 Remove duplicate definitions.
5131 * w32fns.c: Include w32common.h; include w32heap.h only in
5134 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5135 Use `report_file_error' instead of `error' in order to better
5136 inform users of what went wrong. Increase NTGUI_UNICODE file
5137 dialog box file name length to 32k, the maximum allowed by the NT
5140 * w32common.h: New file.
5141 (ROUND_UP, ROUND_DOWN, get_page_size)
5142 (get_allocation_unit, get_processor_type, get_w32_major_version)
5143 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5144 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5145 (OS_NT, os_subtype, cache_system_info): Move here.
5147 * unexw32.c, unexcw.c: Include w32common.h.
5149 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5150 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5151 to call syms_of_w32select.
5153 * cygw32.h: Remove obsolete EXFUN declarations.
5155 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5157 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5158 of w32inevt.o from SOME_MACHINE_OBJECTS.
5160 2012-10-08 Daniel Colascione <dancol@dancol.org>
5162 * image.c: Permanent fix for JPEG compilation issue --- limit
5163 jpeglib `boolean' redefinition to Cygwin builds.
5165 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5167 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5169 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5172 2012-10-08 Daniel Colascione <dancol@dancol.org>
5174 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5175 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5176 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5177 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5178 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5179 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5180 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5181 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5182 now a supported configuration.
5184 * Makefile.in: consolidate image variables into LIBIMAGE; add
5185 W32_OBJ and W32_LIBS. Compile new files.
5188 (_DebPrint) declare tracing facility for W32 debugging. We need
5189 to unify tracing later.
5191 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5192 unconditional use of W32 Unicode functions. Cygwin runs only on
5193 100% Unicode operating systems.
5195 * cygw32.c: New file. Define Cygwin-specific facilities.
5196 (Fcygwin_convert_path_to_windows)
5197 (Fcygwin_convert_path_from_windows): New user functions for
5198 accessing Cygwin path-munging routines.
5200 * cygw32.h: New file.
5201 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5202 UTF-16LE strings temporarily inside non-Lisp-visible string
5205 (w32_strerror): Just what it says on the tin.
5207 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5208 also run for Cygwin; both systems have the same problem with using
5209 GUI facilities in a forked child. Also call syms_of_cygw32,
5210 syms_of_w32select in correct places.
5212 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5213 needs fork-then-exec for daemon launching.
5215 * font.h: Include frame.h.
5217 * image.c: Use the image library cache machinery only when we're
5218 compiling for native WINDOWSNT; Cygwin can use shared libraries
5219 like any other Unixlike system.
5221 * keyboard.c: Clarify a comment regarding the input loop.
5223 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5224 functions directly instead of trying to detect at runtime that our
5225 host operating system supports them. We make this change for two
5226 reasons: Cygwin lacks support for the multibyte character
5227 conversion functions used by the legacy menu code, and Cygwin
5228 never needs to rely on non-Unicode APIs.
5230 * unexw32.c (hinst): Declare extern.
5232 * w32.c: Change header order;
5233 (w32_strerror): Move to w32fns.c because we need it for
5234 non-WINDOWSNT builds.
5236 * w32.h: Add #error macro to make sure we don't include w32.h for
5237 Cygwin builds. Remove w32select declarations.
5239 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5240 w32fns.c. w32console.c is WINDOWSNT-only.
5242 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5243 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5245 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5246 (w32_major_version, w32_minor_version, w32_build_number)
5247 (os_subtype, sound_type): Define here
5248 (w32_defined_color): Make color parameter const for consistency
5249 with other _defined_color functions.
5250 (w32_createwindow): Unconditionally call w32_init_class instead of
5251 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5252 through the code is complex and unnecessary because class
5253 registration is practically free.
5254 (w32_name_of_message): New EMACSDEBUG-only function.
5255 (Fset_message_beep): Move here
5256 (Fx_open_connection): Require that the display name for Windows be
5257 "w32" for consistency, emacsclient disambiguation, and maybe, one
5258 day, multi-window-system support.
5259 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5260 Cygwin files for W32 GUI facilities, since these clearly don't
5261 expect Cygwin names.
5262 (_DebPrint): Define.
5263 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5264 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5265 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5266 (w32_last_error): Remove.
5268 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5270 * w32heap.c (syspage_mask): Declare here.
5271 (cache_system_info): Remove.
5273 * w32inevt.c (faked_key): Define globally, not statically.
5274 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5275 (w32_console_toggle_lock_key): Move to w32fns.c.
5277 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5279 * w32proc.c (_DebPrint): Move to w32fns.c.
5280 * w32select.c: Include string.h, stdio.h for Cygwin.
5281 * w32select.h: New File.
5283 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5285 (w32_message_fd): New variable. Under Cygwin, holds the file
5286 descriptor the system used to tell us about pending thread
5289 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5290 that prevented compilation under non-WINDOWSNT systems.
5292 (w32_initialize): Open /dev/windows and assign it to
5293 w32_message_fd. Provide w32 feature.
5295 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5296 (WM_EMACS_INPUT_READY): add.
5297 (prepend_msg, w32_message_fd): Declare globally.
5300 (keyboard_handle): Use only when WINDOWSNT.
5301 (notify_msg_ready): New function. Posts a message to the main
5302 thread's message queue under CYGWIN, which wakes up the main
5303 thread from select(2) by making the /dev/windows file descriptor
5304 ready. Under WINDOWSNT, it sets an event the same way the old
5307 (post, prepend_msg): Actually call notify_msg_ready instead of
5308 setting the input event directly.
5310 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5312 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5313 but it still has blocs in it, don't return it to the system,
5314 instead of aborting. (Bug#12402)
5316 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5318 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5320 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5321 MAC_OS_X_VERSION_10_6.
5322 (syms_of_nsterm): Remove comment about Panther and above for
5324 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5325 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5326 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5328 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5329 MAC_OS_X_VERSION_10_4.
5331 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5332 MAC_OS_X_VERSION_10_2.
5334 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5336 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5337 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5339 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5340 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5341 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5342 Remove ns_in_resize check.
5343 (ns_clear_frame_area): Remove resize handle code.
5345 * nsfns.m (ns_in_resize): Remove.
5346 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5347 Remove ns_in_resize check.
5349 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5351 Improve sys_siglist detection.
5352 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5353 defined as a macro, as is done in Solaris.
5354 (sys_siglist_entries): New macro.
5355 (save_strsignal): Use it.
5356 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5357 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5359 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5361 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5362 fullscreen/Fullscreen.
5364 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5365 tobar_height is new.
5367 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5368 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5369 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5370 (windowDidResize:): Check for correct window if old style fullscreen.
5371 Capitalize word in comment. Remove incorrect comment.
5372 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5373 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5374 error in drawing background.
5375 (toggleFullScreen:): Remove comment. Rearrange calls.
5376 Set toolbar values to zero, save old height in tobar_height.
5377 Restore tool bar height when leaving fullscreen.
5378 (canBecomeMainWindow): New function.
5380 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5382 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5384 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5386 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5388 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5389 that time stamps of directories could also be changed.
5390 Don't request the too broad GENERIC_WRITE, only the more restrictive
5391 FILE_WRITE_ATTRIBUTES access rights.
5393 * fileio.c (Fset_file_times): Special-case ignoring errors for
5394 directories only on MSDOS, not on MS-Windows.
5396 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5398 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5400 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5402 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5403 see whether CreateFile failed.
5405 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5407 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5408 to avoid similar races.
5409 * keyboard.c (pending_signals): Now bool, not int.
5411 Port timers to OpenBSD, plus check for timer failures.
5412 OpenBSD problem reported by Han Boetes.
5413 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5415 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5416 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5417 like OpenBSD, which has timer_settime but does not declare it.
5418 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5419 whether to use itimerspec-related primitives. All uses of
5420 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5422 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5424 * profiler.c (handle_profiler_signal): Fix a malloc race
5425 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5427 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5429 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5431 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5433 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5434 consistent with the change in return value of 'safe_strsignal'.
5436 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5438 Prefer plain 'static' to 'static inline' (Bug#12541).
5439 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5440 (bidi_set_sor_type, bidi_push_embedding_level)
5441 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5442 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5443 (bidi_cache_search, bidi_cache_ensure_space)
5444 (bidi_cache_iterator_state, bidi_cache_find)
5445 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5446 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5447 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5448 Now 'static', not 'static inline'.
5450 Count overruns when profiling; change units to ns.
5451 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5452 Give extra weight to samples after overruns, to attempt to count
5453 the time more accurately.
5454 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5455 the underlying primitives nominally do ns.
5456 (Fprofiler_cpu_start): Document the change. Mention that
5457 the sampling intervals are only approximate.
5459 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5461 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5463 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5464 case for the special 0 coding-system.
5466 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5467 (Fmake_overlay): Remove redundant tests.
5468 (fix_start_end_in_overlays): Remove redundant recentering.
5470 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5472 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5473 Update dependencies.
5475 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5477 Fix a malloc race condition involving strsignal.
5478 A signal can arrive in the middle of a malloc, and Emacs's signal
5479 handler can invoke strsignal, which can invoke malloc, which is
5480 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5481 Fix it by altering the signal handler so that it does not invoke
5483 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5484 * process.c (status_message): Use const pointer, in case strsignal
5485 is #defined to safe_strsignal.
5486 * sysdep.c (sys_siglist, init_signals): Always define and
5487 initialize a substitute sys_siglist if the system does not define
5488 one, even if HAVE_STRSIGNAL.
5489 (safe_strsignal): Rename from strsignal. Always define,
5490 using sys_siglist. Return a const pointer.
5491 * syssignal.h (safe_strsignal): New decl.
5492 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5494 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5496 * w32proc.c (timer_loop): Fix code that waits for timer
5497 expiration, to avoid high CPU usage.
5499 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5501 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5502 (sweep_weak_table): Remove redundant prototypes.
5504 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5506 * emacs.c: Move the inclusion of TERM_HEADER after including
5507 windows.h on WINDOWSNT. This avoids compilation problems with
5510 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5512 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5513 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5514 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5515 as the previous version used 'void *'.
5517 * ralloc.c (ROUNDUP): Fix last change.
5518 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5521 * w32proc.c <disable_itimers>: New static flag.
5522 (init_timers): Initialize it to zero, after creating the critical
5523 sections used by the timer threads.
5524 (term_timers): Set to 1 before deleting the critical sections.
5525 (getitimer, setitimer): If disable_itimers is non-zero, return an
5526 error indication without doing anything. Reported by Fabrice
5527 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5528 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5530 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5533 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5534 term_ntproc after all the other bookkeeping, to get timers working
5535 as long as possible.
5537 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5539 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5540 Suggested by Juri Linkov in
5541 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5543 Prefer plain 'static' to 'static inline' (Bug#12541).
5544 With static functions, modern compilers inline pretty well by
5545 themselves; advice from programmers often hurts as much as it helps.
5546 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5547 this change shrinks the text size of the Emacs executable by 1.1%
5548 without affecting CPU significantly in my benchmark.

5921 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5922 Since this stuff is now private to charset.c, there's no need for
5923 a public macro and no need to inline by hand.

5991 * w32proc.c (sys_signal): Handle all signals defined by the
5992 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5993 handlers for signals supported by Windows. Don't override
5994 term_ntproc as the handler for SIGABRT.
5995 (sigaction): Rewrite to call sys_signal instead of duplicating its
5997 (sys_kill): Improve commentary.
5999 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6000 consistency with a signature of a signal handler. All callers
6002 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6003 install term_ntproc as a signal handler for SIGABRT, as that
6004 should be done by the dumped Emacs.
6006 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6008 * w32select.c (term_w32select): Protect against repeated
6009 invocation by setting clipboard_owner to NULL after calling
6012 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
6013 and term_ntproc to their modified signatures.
6015 * character.c (char_string, string_char): Remove calls to
6016 MAYBE_UNIFY_CHAR. See the discussion starting at
6017 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
6020 2012-09-25 Chong Yidong <cyd@gnu.org>
6022 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
6024 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6026 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6027 when encountering an unknown bytecode.
6029 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6031 image.c, indent.c: Use bool for booleans.
6032 * dispextern.h (struct image_type): Members valid_p, load, init
6033 now return bool, not int. All uses changed.
6034 * image.c: Omit unnecessary static decls.
6035 (x_create_bitmap_mask, x_build_heuristic_mask):
6036 Return void, not int, since callers don't care about the return value.

6065 Use bool for booleans.
6067 2012-09-24 Chong Yidong <cyd@gnu.org>
6069 * chartab.c (Fset_char_table_default): Obsolete function removed.
6071 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6073 Move pid_t related decls out of lisp.h.
6074 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6075 (interruptible_wait_for_termination):
6076 Move these decls from lisp.h to syswait.h, since they use pid_t.
6077 Needed on FreeBSD; see Herbert J. Skuhra in
6078 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6079 * callproc.c: Include syswait.h.
6081 gnutls.c, gtkutil.c: Use bool for boolean.

6096 * nsmenu.m (ns_update_menubar):
6097 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
6098 * xfns.c (Fx_show_tip) [USE_GTK]:
6099 Use bool for boolean.
6100 * gtkutil.c (xg_update_frame_menubar):
6101 * xmenu.c (update_frame_menubar):
6102 Return void, not int, since caller ignores return value.
6103 * gtkutil.c (xg_change_toolbar_position):
6106 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6108 * makefile.w32-in (BLOCKINPUT_H): Remove.

6125 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6127 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6128 fatal_error_backtrace.
6130 * w32proc.c (sys_kill): Undo last change: don't do anything when
6131 invoked to deliver SIGABRT to our own process. This is now
6132 handled by emacs_raise.
6134 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6136 * w32term.c (w32_read_socket): Remove leftover reference to
6137 interrupt_input_pending.
6139 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6141 Do not use SA_NODEFER.
6142 Problem reported by Dani Moncayo in
6143 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6145 * sysdep.c (emacs_abort): Do not reset signal handler.
6146 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6147 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6148 wanted even on POSIXish hosts, and it doesn't work on Windows.
6150 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6152 * xterm.c (x_term_init): Call fixup_locale before and after calling
6153 gtk_init (Bug#12392).
6155 2012-09-23 Chong Yidong <cyd@gnu.org>
6157 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6158 Vdynamic_library_alist.
6160 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6161 (Fgnutls_available_p): Caller changed.
6163 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6164 (Flibxml_parse_xml_region): Likewise.
6166 * dispextern.h (struct image_type): Remove arg from init function.
6168 * image.c (Finit_image_library, lookup_image_type)
6169 (define_image_type): Remove now-unneeded second arg.
6170 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6171 (init_tiff_functions, init_gif_functions, init_svg_functions):
6172 Arglist and w32_delayed_load calling convention changed.
6173 (gs_type): Remove init_gs_functions; there is no such function.
6174 (valid_image_p, make_image): Fix caller to lookup_image_type.
6176 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6178 Simplify and avoid signal-handling races (Bug#12471).
6180 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6181 Avoid recursive loop if there's a fatal error in the function itself.
6182 * atimer.c (pending_atimers):
6183 * blockinput.h: Don't include "atimer.h"; no longer needed.
6184 (interrupt_input_pending): Remove. All uses removed.
6185 pending_signals now counts both atimers and ordinary interrupts.
6186 This is less racy than having three separate pending-signal flags.
6187 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6189 Rename from their upper-case counterparts BLOCK_INPUT,
6190 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6191 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6192 This makes it easier to access volatile variables more accurately.
6193 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6194 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6195 that's more reliable if the code is buggy and sets
6196 interrupt_input_blocked to a negative value. All uses changed.
6197 * atimer.c (deliver_alarm_signal):
6198 Remove. No need to deliver this to the parent; any thread can
6199 handle this signal now. All uses replaced by underlying handler.
6200 * atimer.c (turn_on_atimers):
6201 * dispnew.c (handle_window_change_signal):
6202 * emacs.c (handle_danger_signal):
6203 * keyboard.c (kbd_buffer_get_event):
6204 Don't reestablish signal handler; not needed with sigaction.
6205 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6207 Rework to avoid unnecessary accesses to volatile variables.
6208 (UNBLOCK_INPUT_TO): Now a function.
6209 (totally_unblock_input, unblock_input): New decls.
6210 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6211 (init_data): Remove. Necessary stuff now done in init_signal.
6212 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6213 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6214 (fatal_error_code): Remove; no longer needed.
6215 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6216 it doesn't always backtrace. All uses changed. No need to reset
6217 signal to default, since sigaction and/or die does that for us now.
6218 Use emacs_raise (FOO), not kill (getpid (), FOO).
6219 (main): Check more-accurately whether we're dumping.
6220 Move fatal-error setup to sysdep.c
6221 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6222 * gtkutil.c (xg_get_file_name, xg_get_font):
6223 Remove no-longer-needed signal-mask manipulation.
6224 * keyboard.c, process.c (POLL_FOR_INPUT):
6225 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6226 * keyboard.c (read_avail_input): Remove.
6227 All uses replaced by gobble_input.
6228 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6229 (kbd_buffer_store_event_hold, gobble_input):
6230 (record_asynch_buffer_change) [USABLE_SIGIO]:
6231 (store_user_signal_events):
6232 No need to mess with signal mask.
6233 (gobble_input): If blocking input and there are terminals, simply
6234 set pending_signals to 1 and return. All hooks changed to not
6235 worry about whether input is blocked.
6236 (process_pending_signals): Clear pending_signals before processing
6237 them, in case a signal comes in while we're processing.
6238 By convention callers now test pending_signals before calling us.
6239 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6240 New functions, to support changes to blockinput.h.
6241 (handle_input_available_signal): Now extern.
6242 (reinvoke_input_signal): Remove. All uses replaced by
6244 (quit_count): Now volatile, since a signal handler uses it.
6245 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6246 All callers changed. Block SIGINT only if not already blocked.
6247 Clear sigmask reliably, even if Fsignal returns, which it can.
6248 Omit unnecessary accesses to volatile var.
6249 (quit_throw_to_read_char): No need to restore sigmask.
6250 * keyboard.c (gobble_input, handle_user_signal):
6251 * process.c (wait_reading_process_output):
6252 Call signal-handling code rather than killing ourselves.
6253 * lisp.h: Include <float.h>, for...
6254 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6255 (pending_signals): Now volatile.
6256 (syms_of_data): Now const if IEEE floating point.
6257 (handle_input_available_signal) [USABLE_SIGIO]:
6258 (terminate_due_to_signal, record_child_status_change): New decls.
6259 * process.c (create_process): Avoid disaster if memory is exhausted
6260 while we're processing a vfork, by tightening the critical section
6262 (send_process_frame, process_sent_to, handle_pipe_signal)
6263 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6265 (send_process): No need for setjmp/longjmp any more, since the
6266 SIGPIPE stuff is now gone. Instead, report an error if errno
6268 (record_child_status_change): Now extern. PID and W are now args.
6269 Return void, not bool. All callers changed.
6270 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6271 Remove. All uses removed. This bug should be fixed now in a
6273 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6274 and record the child status change directly. This avoids the
6275 need to futz with the signal mask.
6276 (process_fatal_action): Move here from emacs.c.
6277 (emacs_sigaction_flags): New function, containing
6278 much of what used to be in emacs_sigaction_init.
6279 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6280 caught by emacs, to make races less likely.
6281 (deliver_process_signal): Rename from handle_on_main_thread.
6283 (BACKTRACE_LIMIT_MAX): Now at top level.
6284 (thread_backtrace_buffer, threadback_backtrace_pointers):
6286 (deliver_thread_signal, deliver_fatal_thread_signal):
6287 New functions, for more-accurate delivery of thread-specific signals.
6288 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6289 (deliver_arith_signal): Handle in this thread, not
6290 in the main thread, since it's triggered by this thread.
6291 (maybe_fatal_sig): New function.
6292 (init_signals): New arg DUMPING so that we can be more accurate
6293 about whether we're dumping. Caller changed.
6294 Treat thread-specific signals differently from process-general signals.
6295 Block all signals while handling fatal error; that's safer.
6296 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6298 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6299 Ignore SIGPIPE unless batch.
6300 (emacs_backtrace): Output backtrace for the appropriate thread,
6301 which is not necessarily the main thread.
6302 * syssignal.h: Include <stdbool.h>.
6303 (emacs_raise): New macro.
6304 * xterm.c (x_connection_signal): Remove; no longer needed
6305 now that we use sigaction.
6306 (x_connection_closed): No need to mess with sigmask now.
6307 (x_initialize): No need to reset SIGPIPE handler here, since
6308 init_signals does this for us now.
6310 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6312 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6313 background rect may be larger (Bug#12245).
6315 2012-09-23 Chong Yidong <cyd@gnu.org>
6317 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6319 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6321 * .gdbinit: Just stop at fatal_error_backtrace.
6322 See Stefan Monnier's request in
6323 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6324 Remove no-longer-used query of system type.
6326 2012-09-22 Chong Yidong <cyd@gnu.org>
6328 * search.c (Freplace_match): Doc fix (Bug#12325).
6330 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6332 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6333 (Fline_end_position): Doc fix.
6335 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6337 2012-09-22 Chong Yidong <cyd@gnu.org>
6339 * dispextern.h (struct image_type): Add new slot, storing a type
6340 initialization function.
6342 * image.c (define_image_type): Call the image initializer function
6343 if it is defined. Arguments and return value changed.
6344 (valid_image_p, make_image): Callers changed.
6345 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6346 (gif_type, imagemagick_type, svg_type, gs_type):
6347 Add initialization functions.
6348 (Finit_image_library): Call lookup_image_type.
6349 (CHECK_LIB_AVAILABLE): Macro deleted.
6350 (lookup_image_type): Call define_image_type here, rather than via
6351 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6352 (syms_of_image): Move define_image_type calls for xbm_type and
6353 pbm_type to lookup_image_type.
6355 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6357 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6358 'idle_timers' from here ...
6359 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6360 lists, to avoid infloops when the timer does something stupid,
6361 like reinvoke itself with the same or smaller time-out.
6364 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6366 * window.c (Fsplit_window_internal): Handle only Qt value of
6367 Vwindow_combination_limit separately.
6368 (Qtemp_buffer_resize): New symbol.
6369 (Vwindow_combination_limit): New default value.
6372 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6374 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6375 the new overlay string. (Bug#10159)
6377 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6379 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6380 or that fprintf is async-signal-safe. POSIX doesn't require
6383 2012-09-22 Chong Yidong <cyd@gnu.org>
6385 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6388 2012-09-22 Kenichi Handa <handa@gnu.org>
6390 * composite.c (composition_reseat_it): Handle the case that a
6391 grapheme cluster is not covered by a single font (Bug#12352).
6393 2012-09-21 Chong Yidong <cyd@gnu.org>
6395 * image.c (define_image_type): Avoid adding duplicate types to
6396 image_types (Bug#12463). Suggested by Jörg Walter.
6398 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6400 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6401 (print_load_command_name): Add case LC_DATA_IN_CODE.
6402 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6404 2012-09-21 Glenn Morris <rgm@gnu.org>
6406 * eval.c (Frun_hook_with_args_until_success)
6407 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6409 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6411 * fileio.c (Ffile_selinux_context): Only call freecon when
6412 lgetfilecon succeeded.
6413 (Fset_file_selinux_context): Likewise. (Bug#12444)
6415 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6417 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6418 reordering, locate the cursor by calling set_cursor_from_row; if
6419 that fails, clear the desired glyph matrix before returning a
6420 failure indication to the caller. Fixes leaving garbled display
6421 when fast scrolling with a down-key. (Bug#12403)
6422 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6423 scrolling through multibyte text.
6425 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6427 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6428 calling mark_vectorlike since that's the one that marks the window.
6429 (mark_discard_killed_buffers): Mark the final cdr.
6430 * window.h (struct window): Move prev/next_buffers to the
6431 non-standard fields.
6432 * window.c (make_window): Initialize prev/next_buffers manually.
6434 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6436 Omit unused arg EXPECTED from socket hooks.
6437 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6438 * nsterm.m (ns_term_init):
6439 * termhooks.h (struct terminal.read_socket_hook):
6440 * w32inevt.c (w32_console_read_socket):
6441 * w32term.c (w32_read_socket):
6442 * xterm.c (XTread_socket):
6443 Omit unused arg EXPECTED. All callers changed.
6444 (store_user_signal_events): Return void, not int, since callers no
6445 longer care about the return value. All uses changed.
6447 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6449 * w32gui.h (XParseGeometry): Do not declare.
6451 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6453 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6454 Ignore 'expected'. See Eli Zaretskii in
6455 <http://bugs.gnu.org/12471#8> (last line).
6457 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6458 (XParseGeometry): Now static. Substitute extremal values for
6459 values that are out of range.
6461 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6463 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6465 * nsfns.m (XParseGeometry): Remove.
6466 (Fx_create_frame): Call x_set_offset to correctly interpret
6467 top_pos in geometry.
6469 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6470 (Fx_parse_geometry): If there is a space in string, call
6471 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6473 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6475 * search.c (scan_buffer): Use character positions in calls to
6476 region_cache_forward and region_cache_backward, not byte
6477 positions. (Bug#12196)
6479 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6480 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6482 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6483 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6484 emacs_blocked_malloc, now deleted.
6486 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6488 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6489 The workaround was for improving performance on Solaris 2.4, but
6490 is getting in the way now. Emacs will still work if someone is
6491 still running Solaris 2.4 in a museum somewhere; Sun dropped
6492 support for Solaris 2.4 in 2003.
6493 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6494 * process.c (create_process) [HAVE_WORKING_VFORK]:
6495 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6496 since Emacs no longer uses vfork on that platform.
6498 2012-09-17 Glenn Morris <rgm@gnu.org>
6500 * emacs.c: Use COPYRIGHT.
6502 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6504 Remove configure's --without-sync-input option (Bug#12450).
6505 When auditing signal-handling in preparation for cleaning it up,
6506 I found that SYNC_INPUT has race conditions and would be a real
6507 pain to fix. Since it's an undocumented and deprecated
6508 configure-time option, now seems like a good time to remove it.
6509 Also see <http://bugs.gnu.org/11080#16>.
6510 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6511 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6512 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6513 (malloc_hysteresis):
6514 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6515 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6516 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6517 (dont_register_blocks, bytes_used_when_reconsidered)
6518 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6519 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6520 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6521 Remove. All uses removed.
6522 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6523 implementation, one that depends on whether the new macro
6524 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6526 * atimer.c (run_timers, handle_alarm_signal):
6527 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6528 (handle_async_input, process_pending_signals)
6529 (handle_input_available_signal, init_keyboard):
6530 * nsterm.m (ns_read_socket):
6531 * process.c (wait_reading_process_output):
6532 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6533 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6535 * xterm.c (XTread_socket):
6537 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6538 * eval.c (handling_signal): Remove. All uses removed.
6539 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6540 All uses replaced with the SYNC_INPUT version.
6541 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6543 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6546 * font.c (Ffont_shape_gstring): Remove unused local.
6548 2012-09-16 Glenn Morris <rgm@gnu.org>
6550 * Makefile.in (clean): No longer run nextstep's clean.
6552 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6554 (ns-app): Move here from ns.mk, and simplify.
6555 (clean): Simplify nextstep entry.
6556 * ns.mk: Remove file.
6558 2012-09-17 Kenichi Handa <handa@gnu.org>
6560 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6561 not covert the last few charactes.
6563 2012-09-16 Kenichi Handa <handa@gnu.org>
6565 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6566 here, but just check the validity of glyphs in the glyph-string.
6568 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6570 * window.c (Fwindow_parameter, Fset_window_parameter):
6571 Accept any window as argument (Bug#12452).
6573 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6575 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6576 to ns_term_init to avoid memory leak.
6578 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6579 explicit retain/release.
6580 (ns_term_init): Only allow one display. Initialize outerpool and
6583 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6585 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6586 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6587 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6588 the Microsoft problem in a different way, by altering ../nt/config.nt.
6590 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6605 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6606 by lisp.h. This completes removal of setjmp.h inclusion
6607 erroneously announced in the previous commit. (Bug#12446)
6609 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6612 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6613 not defined as a macro. The latter happens on MS-Windows.
6616 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6618 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6619 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6620 Some instances of '#include <setjmp.h>' removed, if the
6621 only reason for the instance was because "lisp.h" was included.
6622 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6623 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6624 and _longjmp with the new symbols. Emacs already uses _setjmp if
6625 available, so this change affects only POSIXish hosts that have
6626 sigsetjmp but not _setjmp, such as some versions of Solaris and
6627 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6628 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6629 (png_load_body) [HAVE_PNG]:
6630 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6631 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6632 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6633 since PNG requires jmp_buf. This is the only exception to the
6634 general rule that we now use sys_setjmp and sys_longjmp.
6635 This exception is OK since this code does not change the signal
6636 mask or longjmp out of a signal handler.
6638 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6640 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6641 Include "syssignal.h", for 'main_thread'.
6643 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6645 Avoid out-of-range marker position (Bug#12426).
6646 * insdel.c (replace_range, replace_range_2):
6647 Adjust markers before overlays, as suggested by comments.
6648 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6649 Remove redundant check before calling offset_intervals.
6651 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6653 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6654 current buffer (Bug#12387).
6656 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6658 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6660 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6662 Use a more backwards-compatible timer format (Bug#12430).
6663 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6664 vector element, not from the 4th, since PSECS is now at the end.
6665 (Fcurrent_idle_time): Doc fix.
6667 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6669 Function to mark objects and remove killed buffers at once.
6670 * alloc.c (discard_killed_buffers): Rename to ...
6671 (mark_discard_killed buffers) ... new name. Add marking
6672 of remaining objects. Fix comment. Adjust users.
6673 (mark_object): Do not touch frame buffer lists here.
6674 * frame.c (delete_frame): Reset frame buffer lists here.
6676 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6678 Better workaround for GNOME bug when --enable-gcc-warnings.
6679 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6680 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6681 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6683 Simplify SIGIO usage (Bug#12408).
6684 The code that dealt with SIGIO was crufty and confusing, e.g., it
6685 played tricks like "#undef SIGIO" but these tricks were not used
6686 consistently. Simplify mostly by not #undeffing standard symbols,
6687 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6688 or not as we please) rather than "defined SIGIO" (standard symbol
6689 that we probably shouldn't #undef).
6690 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6691 Modules that need it can include it.
6692 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6693 * dispextern.h (ignore_sigio): New decl.
6694 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6695 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6696 * emacs.c (shut_down_emacs):
6697 * keyboard.c (kbd_buffer_store_event_hold):
6698 Use ignore_sigio rather than invoking 'signal' directly.
6699 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6701 (FIONREAD, SIGIO): Do not #undef.
6702 (tty_read_avail_input): Use #error rather than a syntax error.
6703 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6704 for I_PIPE, used by SETUP_SLAVE_PTY.
6705 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6706 * sysdep.c (croak): Remove; no longer needed. This bit of
6707 temporary code, with Fred N. Fish's comment that it's temporary,
6708 has been in Emacs since at least 1992!
6709 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6710 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6711 * syssignal.h (croak): Remove decl.
6712 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6713 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6714 now that we're termios-only.
6715 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6716 * term.c (dissociate_if_controlling_tty): Use #error rather than
6719 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6720 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6721 to work around GNOME bug 683906.
6722 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6723 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6724 This works around GCC bug 54561.
6726 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6728 More fixes for 'volatile' and setjmp/longjmp.
6729 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6730 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6731 (png_load_body) [HAVE_PNG]:
6732 (jpeg_load_body) [HAVE_JPEG]:
6733 New function, with most of the old parent function's body.
6734 (png_load) [HAVE_PNG]:
6735 (jpeg_load) [HAVE_JPEG]:
6736 Invoke the new function, to avoid longjmp munging our locals.
6737 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6738 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6739 longjmp is passed 2, as the C standard doesn't guarantee this.
6740 Instead, store the failure code into mgr->failure_code.
6742 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6744 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6745 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6746 (syms_of_keyboard): Remove support for unread-command-char.
6748 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6750 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6751 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6752 violation. (Bug#12426)
6754 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6756 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6758 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6760 * eval.c: Add `inhibit-debugger'.
6761 (Qinhibit_debugger): New symbol.
6762 (call_debugger): Bind it instead of Qdebug_on_error.
6763 (maybe_call_debugger): Test Vinhibit_debugger.
6764 (syms_of_eval): Define inhibit-debugger.
6765 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6766 (syms_of_xdisp): Remove inhibit-debug-on-message.
6768 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6770 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6771 If a nonvolatile local variable is written before a _longjmp to
6772 the frame containing the variable, and is read after the _longjmp,
6773 the value read is indeterminate. Some local variables of type
6774 'struct handler' and 'struct catchtag' are used in this way, so
6775 mark each of their slots as volatile if the slot can be set before
6776 _longjmp and read afterwards.
6777 * lisp.h (struct handler): var and chosen_clause are now volatile.
6778 (struct catchtag): val, next, and pdlcount are now volatile.
6780 * bidi.c (bidi_push_it, bidi_pop_it):
6781 * fns.c (copy_hash_table):
6782 * image.c (define_image_type):
6783 * keyboard.c (kbd_buffer_store_event_hold):
6784 * process.c (Fprocess_send_eof):
6785 * xfaces.c (x_create_gc) [HAVE_NS]:
6786 * xgselect.c (xg_select):
6787 Prefer assignment to memcpy when either will do.
6789 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6790 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6791 time an item is removed. No need to mark this function 'inline';
6792 the compiler knows better than we do.
6794 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6796 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6797 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6798 to change_frame_size (Bug#12388).
6799 (windowDidResize:): Pass YES to updateFrameSize.
6801 * nsterm.h: Add delay parameter to updateFrameSize.
6803 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6805 Discard killed buffers from deleted window and frame objects.
6806 This reduces an amount of references to killed buffers and
6807 helps GC to reclaim them faster.
6808 * alloc.c (discard_killed_buffers): New function.
6809 (mark_object): Use it for deleted windows and frames.
6810 (mark_object): If symbol's value is set up for a killed buffer
6811 or deleted frame, restore its global binding.
6812 * data.c (swap_in_global_binding): Add GC notice.
6813 (swap_in_symval_forwarding): Use convenient set_blv_where.
6814 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6815 * window.h: ... to here.
6817 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6819 Convenient macro to check whether the buffer is live.
6820 * buffer.h (BUFFER_LIVE_P): New macro.
6821 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6822 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6824 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6826 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6827 composition cases (Bug#12364).
6829 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6830 overhang of succeeding glyphs overlapping box cursor.
6832 * w32term.c (x_draw_glyph_string): Likewise.
6834 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6836 Simplify, document, and port floating-point (Bug#12381).
6837 The porting part of this patch fixes bugs on non-IEEE platforms
6838 with frexp, ldexp, logb.
6839 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6841 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6842 support, by removing commented-out code and briefly listing the
6843 C89 functions excluded. The commented-out stuff was confusing
6844 maintenance, e.g., we thought we needed cbrt but it was commented out.
6845 (logb): Remove decl; no longer needed.
6846 (isfinite): New macro, if not already supplied.
6847 (isnan): Don't replace any existing macro.
6848 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6849 are present on all C89 platforms.
6850 (Ffrexp): Do not special-case zero, as frexp does the right thing
6852 (Flogb): Do not use logb, as it doesn't have the desired meaning
6853 on hosts that use non-base-2 floating point. Instead, stick with
6854 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6855 frexp, to avoid getting an unspecified result.
6857 * xdisp.c (Qinhibit_debug_on_message): Now static.
6859 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6861 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6862 NSBezierPath (Bug#12131).
6864 2012-09-10 Chong Yidong <cyd@gnu.org>
6866 * fns.c (Fdelq, Fdelete): Doc fix.
6868 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6870 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6871 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6873 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6875 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6876 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6879 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6881 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6882 left fringe if the window has a left margin. This avoids leaving
6883 traces of the cursor because its leftmost pixel is not drawn over.
6885 * dispnew.c (update_window_line): When the left margin area of a
6886 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6887 that screen line. (Bug#12277)
6889 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6891 Assume C89 or later for math functions (Bug#12381).
6892 This simplifies the code, and makes it a bit smaller and faster,
6893 and (most important) makes it easier to clean up signal handling
6894 since we can stop worring about floating-point exceptions in
6895 library code. That was a problem before C89, but the problem
6896 went away many years ago on all practical Emacs targets.
6897 * data.c, image.c, lread.c, print.c:
6898 Don't include <math.h>; no longer needed.
6899 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6900 might be autoconfigured, as that never happens.
6902 * doprnt.c (DBL_MAX_10_EXP):
6903 * print.c (DBL_DIG):
6904 Remove. C89 or later always defines these.
6905 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6906 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6907 (arith_error, domain_error, domain_error2):
6908 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6909 no longer needed -- we simply return what C returns. All uses removed.
6910 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6912 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6913 Remove. All uses expanded, as these macros are no longer used
6914 more than once and are now more trouble than they're worth.
6915 (Ftan): Use tan, not sin / cos.
6916 (Flogb): Assume C89 frexp.
6917 (fmod_float): Assume C89 fmod.
6918 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6919 (init_floatfns): Remove. All uses removed.
6921 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6923 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6924 compositeToPoint for OSX < 10.6 (Bug#12390).
6926 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6928 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6929 This produces more-accurate results.
6931 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6933 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6934 changes (Bug#12088).
6936 2012-09-08 Chong Yidong <cyd@gnu.org>
6938 * syntax.c (Fstring_to_syntax): Doc fix.
6940 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6942 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6943 in the internal border.
6944 (x_set_window_size): Remove static variables and their usage.
6945 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6946 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6947 Remove fringe/internal border adjustment (Bug#11052).
6948 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6949 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6950 (ns_fix_rect_ibw): Remove.
6951 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6952 (ns_dumpglyphs_box_or_relief): Ditto.
6953 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6955 (ns_dumpglyphs_image): Ditto.
6956 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6958 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6959 their usage. Add fringe_extended_p and its use as in other terms.
6960 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6961 scroll bar was removed.
6962 (updateFrameSize): New function.
6963 (windowDidResize): Move code to updateFrameSize and call it.
6965 * nsterm.h (EmacsView): Add updateFrameSize.
6967 2012-09-07 Chong Yidong <cyd@gnu.org>
6969 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6971 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6973 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6975 More signal-handler cleanup (Bug#12327).
6976 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6977 Problem introduced when merging patches. Noted by Eli Zaretskii in
6978 <http://bugs.gnu.org/12327#67>.
6979 * floatfns.c: Comment fix.
6980 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6981 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6982 and anyway the declaration is harmless even if SIGDANGER is not defined.
6983 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6984 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6985 source files not surprisingly expected syssignal.h to define, or
6986 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6987 Include <sys/ioctl.h>, for FIONREAD.
6988 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6989 This eliminates a problem whereby other files mysteriously had
6990 to include "syssignal.h" before including "systty.h" if they
6991 wanted to use "#ifdef SIGIO".
6993 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6995 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6997 * w32.c (sigemptyset): Empty the set.
6998 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7000 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7002 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7004 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7005 (mark_object): Likewise for frame objects.
7007 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7009 * syssignal.h (handle_on_main_thread): Always declare,
7010 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7011 This ports to platforms without HAVE_PTHREAD.
7013 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7015 Signal-handler cleanup (Bug#12327).
7016 Emacs's signal handlers were written in the old 4.2BSD style with
7017 sigblock and sigmask and so forth, and this led to some
7018 inefficiencies and confusion. Rewrite these to use
7019 pthread_sigmask etc. without copying signal sets around. Also,
7020 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7021 'signal', and instead use functions that do not attempt to take
7022 over the system name space. This patch causes Emacs's text
7023 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7024 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7025 Do not include <signal.h> or "syssignal.h", as these
7026 modules do not use signals.
7027 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7028 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7029 Do not include <signal.h>, as "syssignal.h" does that for us now.
7030 * atimer.c (sigmask_atimers): New function.
7031 (block_atimers, unblock_atimers): New functions,
7032 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7034 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7035 no longer needed here.
7036 * emacs.c (main): Inspect existing signal handler with sigaction,
7037 so that there's no need to block and unblock SIGHUP.
7038 * sysdep.c (struct save_signal): New member 'action', replacing
7039 old member 'handler'.
7040 (save_signal_handlers, restore_signal_handlers):
7041 Use sigaction instead of 'signal' to save and restore.
7042 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7043 New function. All users of 'signal' modified to use set_sighandler
7044 if they're writeonly, and to use sys_signal if they're read+write.
7045 (emacs_sigaction_init, forwarded_signal): New functions.
7046 (sys_signal): Remove. All uses replaced by calls to sigaction
7047 and emacs_sigaction_init, or by direct calls to 'signal'.
7048 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7049 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7050 all uses replaced by pthread_sigmask etc. calls.
7051 * syssignal.h: Include <signal.h>.
7052 (emacs_sigaction_init, forwarded_signal): New decls.
7053 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7054 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7055 (sigmask, sys_sigmask): Remove; no longer needed.
7056 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7057 (sigblock, sigunblock, sigfree):
7058 (sigsetmask) [!defined sigsetmask]:
7059 Remove. All uses replaced by pthread_sigmask.
7060 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7061 no longer need to be replaced, and its typical old uses
7062 are now done via emacs_sigaction_init and sigaction.
7063 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7064 (sys_sigdel): Remove; unused.
7065 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7067 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7069 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7070 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7072 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7074 Explicitly mark buffer_defaults and buffer_local_symbols.
7075 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7076 mark_local_symbols here.
7077 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7078 since special buffers aren't marked here any more.
7079 (allocate_buffer): Chain new buffer with all_buffers here...
7080 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7082 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7083 (syms_of_buffer): Remove staticpro of the above.
7084 (init_buffer_once): Set names for buffer_defaults and
7085 buffer_local_symbols.
7087 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7089 Use bool for booleans in font-related modules.
7090 * font.c (font_intern_prop, font_style_to_value)
7091 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7092 (generate_otf_features, font_check_otf_features, font_check_otf)
7093 (font_match_p, font_list_entities, font_at):
7094 * fontset.c (fontset_id_valid_p, reorder_font_vector
7095 (fontset_find_font, Fset_fontset_font)
7096 (face_suitable_for_char_p) [0]:
7097 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7098 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7099 (m17n_flt_initialized, ftfont_shape_by_flt):
7100 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7101 * nsfont.m (nsfont_draw):
7102 * w32font.c (w32font_draw):
7103 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7104 Use bool for booleans.
7105 * font.h: Adjust to above API changes.
7106 (struct font, struct font_driver, struct font_driver_list):
7107 Use bool for booleans.
7108 (struct font): Remove useless member encoding_type.
7110 * fontset.c, xftfont.c: Omit unnecessary static decls.
7112 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7114 * alloc.c (mark_object): Revert window marking code
7115 since it's unsafe for the Fset_window_configuration.
7117 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7119 Fix race conditions with signal handlers and errno (Bug#12327).
7120 Be more systematic about preserving errno whenever a signal
7121 handler returns, even if it's not in the main thread. Do this by
7122 renaming signal handlers to distinguish between signal delivery
7123 and signal handling. All uses changed.
7124 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7125 * data.c (deliver_arith_signal): Rename from arith_error.
7126 * dispnew.c (deliver_window_change_signal): Rename from
7127 window_change_signal.
7128 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7129 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7130 * keyboard.c (deliver_input_available_signal): Rename from
7131 input_available_signal.
7132 (deliver_user_signal): Rename from handle_user_signal.
7133 (deliver_interrupt_signal): Rename from interrupt_signal.
7134 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7135 (deliver_child_signal): Rename from sigchld_handler.
7136 * atimer.c (handle_alarm_signal):
7137 * data.c (handle_arith_signal):
7138 * dispnew.c (handle_window_change_signal):
7139 * emacs.c (handle_fatal_signal, handle_danger_signal):
7140 * keyboard.c (handle_input_available_signal):
7141 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7142 * process.c (handle_pipe_signal, handle_child_signal):
7143 New functions, with the actual signal-handling code taken from the
7144 original respective signal handlers, sans the sporadic attempts to
7145 preserve errno, since that's now done by handle_on_main_thread.
7146 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7147 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7148 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7150 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7151 Move initialization of main_thread to sysdep.c's init_signals.
7152 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7153 our usage, and simplifies the mainline code.
7154 (record_child_status_change): New static function, as a helper
7155 for handle_child_signal, and with most of the old child handler's
7157 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7158 (handle_child_signal): Use the above.
7159 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7160 Moved here from emacs.c.
7161 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7162 code moved here from emacs.c's main function.
7163 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7164 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7165 This lets callers save and restore errno properly.
7167 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7169 Remove redundant or unused things here and there.
7170 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7171 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7172 * editfns.c (Fcompare_buffer_substrings): Likewise.
7173 * frame.h (struct terminal, struct font_driver_list):
7174 Remove redundant declarations.
7175 * window.h (Qleft, Qright): Likewise.
7177 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7179 Do not mark objects from deleted buffers, windows and frames.
7180 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7181 (mark_object): Likewise for windows and frames.
7183 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7185 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7186 buffer_defaults and buffer_local_symbols as valid objects.
7187 Return special value to denote them.
7189 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7191 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7192 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7193 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7194 (file_name_absolute_p, Fsubstitute_in_file_name):
7195 (check_executable, check_writable, Ffile_accessible_directory_p)
7196 (Fset_file_selinux_context, Fdefault_file_modes)
7197 (Finsert_file_contents, choose_write_coding_system)
7198 (Fwrite_region, build_annotations, a_write, e_write)
7200 * filelock.c (boot_time_initialized, get_boot_time)
7201 (get_boot_time_1, lock_file_1, within_one_second):
7202 * floatfns.c (in_float):
7203 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7204 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7205 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7206 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7207 * window.c (compare_window_configurations):
7208 Use bool for booleans.
7209 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7210 (Fdefault_file_modes): Now mode_t, not int, for modes.
7211 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7212 (internal_delete_file): Now returns void, not a (boolean) int,
7213 since nobody was looking at the return value.
7214 * lisp.h, window.h: Adjust to above API changes.
7216 * xdisp.c (set_message): Simplify and reindent last change.
7218 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7220 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7222 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7224 * eval.c (call_debugger): Make the function non-static so that we
7225 can call it from set_message.
7227 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7228 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7230 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7232 Give more-useful info on a fatal error (Bug#12328).
7233 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7234 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7235 of doing the work ourselves.
7236 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7237 do most of the work.
7238 (fatal_error_backtrace): New function, taken from the guts
7239 of the old fatal_error_signal, but with a new option to output
7241 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7242 info about the signal than just its number.
7243 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7244 * sysdep.c: Include <execinfo.h>
7245 (emacs_backtrace): New function, taken partly from the previous
7246 code of the 'die' function.
7247 (emacs_abort): Call fatal_error_backtrace rather than abort.
7249 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7251 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7252 eager (load-time) macro-expansion.
7253 * lisp.mk (lisp): Add macroexp.
7255 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7257 Simplify redefinition of 'abort' (Bug#12316).
7258 Do not try to redefine the 'abort' function. Instead, redo
7259 the code so that it calls 'emacs_abort' rather than 'abort'.
7260 This removes the need for the NO_ABORT configure-time macro
7261 and makes it easier to change the abort code to do a backtrace.
7262 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7263 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7264 Remove; sysdep.c's emacs_abort now takes its place.
7265 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7266 'abort' changed to use 'emacs_abort'.
7267 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7268 (abort) [!defined abort]: Rename to ...
7269 (emacs_abort): ... new name.
7270 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7271 the place of the old 'abort' in emacs.c.
7272 * w32.c, w32fns.c (abort): Do not #undef.
7273 * w32.c (emacs_abort): Rename from w32_abort.
7275 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7277 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7278 offsets[j].dv, since the y axis of the screen coordinates points
7279 down, while the y axis of the font definition coordinates points
7280 up. This fixes display of Arabic diacritics such as KASRA and
7281 KASRATAN. (Bug#11860)
7283 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7285 Be more systematic about _setjmp vs setjmp.
7286 * alloc.c (test_setjmp, mark_stack):
7287 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7288 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7289 (png_load, my_error_exit, jpeg_load):
7290 * process.c (send_process_trap, send_process):
7291 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7292 The underscored versions are up to 30x faster on some hosts.
7293 Formerly, the code used setjmp+longjmp sometimes and
7294 _setjmp+_longjmp at other times, with no particular reason to
7295 prefer setjmp+longjmp.

7332 * msdos.c (fatal_error_in_progress): ... from here.

7336 REDISPLAYING_P when unwinding, instead of saving its previous,
7337 always-false value and then restoring it.
7339 Clean up some extern decls.
7340 Mostly, this hoists extern decls out of .c files and into .h files.
7341 That way, we're more likely to catch errors if the interfaces change.

7369 * xterm.c (updating_frame): Remove decl of nonexistent object.
7371 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7372 when building globals.h, as the objects that are not built on
7373 this host are not needed to compile C files on this host.

7427 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7428 more than one grapheme cluster passed to the shaper: compute the
7429 offset adjustment values separately for each cluster. (Bug#11860)
7431 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7432 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7433 about implicit conversions from integer to pointer.
7435 2012-09-01 Daniel Colascione <dancol@dancol.org>
7437 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window

7491 window system declarations.
7493 * frame.h: Move common functions here: set_frame_menubar,
7494 x_set_window_size, x_sync, x_get_focus_frame,
7495 x_set_mouse_position, x_set_mouse_pixel_position,
7496 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7557 * lread.c (init_lread): For out-of-tree builds, only add the
7558 source directory's site-lisp dir to the load-path if it exists,
7559 consistent with in-tree builds. (Bug#12302)

7582 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7583 Add window_closed and button_values. Add void as return value for
7584 add(Button|String|Split). addButton takes int instead of Lisp_Object.

7740 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7741 (valid_lisp_object_p): Likewise.
7743 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7745 * window.c (Fset_window_configuration): Record any window's old
7746 buffer if it's replaced (see Bug#8789). If the new current
7747 buffer doesn't appear in the selected window, go to its old
7750 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7752 Special MEM_TYPE_SPARE to denote reserved memory.
7753 * alloc.c (enum mem_type): New memory type.
7754 (refill_memory_reserve): Use new type for spare memory.
7755 This prevents live_cons_p and live_string_p from incorrect
7756 detection of uninitialized objects from spare memory as live.
7758 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7761 * Makefile.in (.PHONY): versioclean -> versionclean.
7763 Remove unused external symbols.
7764 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7765 * window.c (Qwindow_valid_p, decode_valid_window):
7766 Now static, not extern.
7767 * data.c (Qinterval): Remove; unused.
7768 (syms_of_data): Do not define 'interval'.
7769 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7770 * window.h (decode_valid_window):
7773 * character.c, charset.c, chartab.c: Use bool for booleans.
7774 * character.c (lisp_string_width, string_count_byte8)
7775 (string_escape_byte8):
7776 * charset.c (charset_map_loaded, load_charset_map, read_hex):
7777 (load_charset_map_from_file, map_charset_chars)
7778 (Fdefine_charset_internal, define_charset_internal)
7779 (Fdeclare_equiv_charset, find_charsets_in_text)
7780 (Ffind_charset_region, char_charset, Fiso_charset):
7781 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
7782 (sub_char_table_set, sub_char_table_set_range)
7783 (char_table_set_range, optimize_sub_char_table)
7784 (map_sub_char_table):
7785 Use bool for boolean.
7786 * character.c (str_to_unibyte): Omit last boolean argument; it was
7787 always 0. All callers changed.
7788 * character.h, charset.h: Adjust to match previous changes.
7789 * character.h (char_printable_p): Remove decl of nonexistent function.
7790 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7791 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7792 are all boolean, so make them single-bit bitfields.
7794 * lisp.h (ASET): Remove attempt to detect side effects.
7795 It was meant to be temporary and it often doesn't work,
7796 because when IDX has side effects the behavior of IDX==IDX
7797 is undefined. See Stefan Monnier in
7798 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7800 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7802 * lisp.h (functionp): New function (extracted from Ffunctionp).
7803 (FUNCTIONP): Use it.
7804 * eval.c (Ffunctionp): Use it.
7806 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7808 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7809 as that's faster and simpler than static storage. Don't bother
7810 with the g_main_context_query overhead if g_main_context_pending
7811 says no events are pending.
7812 (gfds, gfds_size): Remove these static vars.
7813 (xgselect_initialize): Remove; no longer needed.
7814 All uses and decls removed.
7816 * emacs.c (fatal_error_signal_hook): Remove.
7817 All uses removed. This leftover from old code was always 0.
7819 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7820 * casefiddle.c (casify_object, casify_region):
7821 * casetab.c (set_case_table):
7822 * category.c, category.h (word_boundary_p):
7823 * category.h (CHAR_HAS_CATEGORY):
7824 Use bool for booleans, instead of int.
7826 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7828 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7830 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7832 On assertion failure, print backtrace if available.
7833 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7834 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7835 * Makefile.in (LIB_EXECINFO): New macro.
7838 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7839 * bytecode.c (exec_byte_code):
7840 * callint.c (check_mark, Fcall_interactively):
7841 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7842 (getenv_internal, sync_process_alive, call_process_exited):
7843 * lisp.h (USE_SAFE_ALLOCA):
7844 Use bool for booleans, instead of int.
7845 * lisp.h, process.h: Adjust prototypes to match above changes.
7846 * callint.c (Fcall_interactively): Don't assume the mark's
7847 offset fits in 'int'.
7849 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7851 * buffer.c, buffer.h: Use bool for boolean.
7852 * buffer.c (reset_buffer_local_variables)
7853 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7854 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7855 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7856 (overlay_touches_p, overlay_strings, Foverlay_put)
7857 (report_overlay_modification, call_overlay_mod_hooks):
7858 (mmap_enlarge, mmap_set_vars):
7859 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7860 Use bool for booleans, instead of int.
7861 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7862 since the 1-or-0 return value is always ignored anyway.
7863 (mmap_initialized_p):
7864 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7865 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7867 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7869 * bidi.c: Use bool for boolean.
7870 This is a bit more readable, and makes the text segment of bidi.o
7871 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7872 Presumably it's faster too.
7873 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7875 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7876 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7877 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7878 (bidi_explicit_dir_char, bidi_level_of_next_char)
7879 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7880 Use bool for booleans, instead of int.
7881 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7882 (bidi_unshelve_cache): Adjust decls to match code.
7884 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7886 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7889 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7891 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7892 * atimer.h: Include <stdbool.h>.
7894 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7896 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7897 compile time tests instead of run time tests on systems that do
7899 (FRAME_MAC_P): Remove leftover from deleted code.
7900 * frame.c (syms_of_frame): Remove leftover from deleted code.
7902 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7904 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7906 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7908 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7909 Otherwise, the compiler complains about (A?B:C) where B is void
7910 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7911 (fontset_add): Return void, for FONTSET_ADD.
7913 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7915 * alloc.c: Use bool for booleans.
7916 (gc_in_progress, abort_on_gc)
7917 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7918 (dont_register_blocks) [GC_MALLOC_CHECK]:
7919 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7920 (check_string_bytes, make_specified_string, memory_full)
7921 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7922 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7923 (mark_stack, valid_pointer_p, make_pure_string)
7924 (Fgarbage_collect, survives_gc_p, gc_sweep):
7925 Use bool for booleans, instead of int.
7926 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7927 Remove unused local.
7928 * alloc.c (PURE_POINTER_P):
7929 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7930 * editfns.c (Fformat):
7931 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7933 * fns.c (sweep_weak_table):
7934 * lisp.h (suppress_checking, push_message, survives_gc_p)
7935 (make_pure_string, gc_in_progress, abort_on_gc):
7936 * lread.c (readchar, read1):
7937 * print.c (Fprin1_to_string):
7938 * xdisp.c (push_message):
7939 Use bool for booleans affected directly or indirectly by
7942 Make recently-introduced setters macros.
7943 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7944 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7945 (set_fontset_default, set_fontset_fallback): Rename from their
7946 upper-case counterparts, and make them functions rather than macros.
7947 This is more consistent with the other recently-introduced setters.
7948 These don't need to be inline, since they're local.
7950 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7952 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7953 the loop (Bug#12247).
7955 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7957 * lisp.h (vcopy): Use memcpy rather than our own loop.
7958 This fixes a performance regression introduced by the recent
7959 addition of vcopy. This means 'vcopy' will need to be modified
7960 for a copying collector, but that's OK. Also, tighten the
7961 checking in the assertion.
7963 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7965 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7966 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7967 non-base glyph for the width of the base character, according to
7968 what x_draw_composite_glyph_string_foreground expects.
7969 Generate WADJUST value according to composition_gstring_width's
7970 expectations, to produce correct width of the composed character.
7971 Reverse the sign of the DU offset produced by ScriptPlace.
7973 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7975 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7977 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7979 Avoid direct writes to contents member of struct Lisp_Vector.
7980 * lisp.h (vcopy): New function to copy data into vector.
7981 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7982 * fns.c (Ffillarray): Use ASET.
7983 * keyboard.c (timer_check_2): Use AREF and ASET.
7984 (append_tool_bar_item, Frecent_keys): Use vcopy.
7985 * lread.c (read_vector): Use ASET.
7986 * msdos.c (Frecent_doskeys): Use vcopy.
7987 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7988 (Finternal_merge_in_global_face): Use ASET and vcopy.
7989 * xfont.c (xfont_list_pattern): Likewise.
7991 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7993 * window.c (Fwindow_point): For the selected window always return
7994 the position of its buffer's point.
7995 (Fset_window_point): For the selected window always go in its
7996 buffer to the specified position.
7998 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8000 Setter macros for fontsets.
8001 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8002 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8003 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8006 2012-08-20 Glenn Morris <rgm@gnu.org>
8008 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8009 Don't assume that `ln -f' works.
8011 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8013 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8014 and later about non-assignments with no effect. See discussion at
8015 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8018 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8020 Inline setter functions for Lisp_Objects slots of struct specbinding.
8021 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8024 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8026 * window.c (select_window): Always make selected window's buffer
8029 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8031 Use AREF and ASET for docstrings of category tables.
8032 * category.h (CATEGORY_DOCSTRING): Use AREF.
8033 (SET_CATEGORY_DOCSTRING): Use ASET.
8034 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8036 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8038 Inline setter functions for hash table members.
8039 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8040 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8041 (set_hash_key_and_value, set_hash_index, set_hash_next)
8042 (set_hash_hash): New functions.
8043 * charset.c, fns.c: Adjust users.
8045 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8047 Inline getter and setter functions for per-buffer values.
8048 * buffer.h (per_buffer_default, set_per_buffer_default)
8049 (per_buffer_value, set_per_buffer_value): New functions.
8050 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8051 * buffer.c, data.c: Adjust users.
8053 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8055 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8057 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8059 Rely on <config.h> + <unistd.h> to declare 'environ',
8060 as gnulib does this if the system doesn't.
8061 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8062 Remove declaration. MS-Windows declares it on stdlib.h which is
8063 included by conf_post.h.
8064 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8065 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8066 * vm-limit.c: Include <unistd.h>, for 'environ'.
8068 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8069 (start_of_data): Remove decl; mem-limits.h provides it.
8071 * xdisp.c (handle_invisible_prop): Make it a bit faster
8072 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8074 2012-08-19 Chong Yidong <cyd@gnu.org>
8076 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8079 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
8081 * .gdbinit: Use call instead of set when calling a function in the
8084 * data.c (set_internal): Don't use set_blv_found.
8085 (Fkill_local_variable): Likewise.
8087 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8089 * nsfont.m (ns_ascii_average_width): Ensure the string
8090 ascii_printable is initialized with a null-terminated character
8091 array. Otherwise, it can contain undesired extra characters.
8093 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8095 port new setting code to Sun C 5.8 2005/10/13
8096 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8097 Return void, not Lisp_Object. Otherwise, the compiler
8098 complains about (A?B:C) where B is void and C is Lisp_Object
8099 when compiling CHAR_TABLE_SET, due to the recent change to
8100 the API of sub_char_table_set_contents.
8102 2012-08-18 Chong Yidong <cyd@gnu.org>
8104 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
8105 for the string case (Bug#3874).
8107 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8109 * buffer.h (BSET): Remove (Bug#12215).
8110 Replace all uses with calls to new setter functions.

8138 * category.c (bset_category_table):
8139 * syntax.c (bset_syntax_table):
8140 New setter functions.
8142 * process.h (PSET): Remove (Bug#12215).
8143 Replace all uses with calls to new setter functions.

8147 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
8148 * process.c (PROCESS_INLINE):
8149 Define to EXTERN_INLINE, so that the corresponding functions
8150 are compiled into code.

8154 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
8155 (pset_type, pset_write_queue): New setter functions.
8157 * window.h (WSET): Remove (Bug#12215).
8158 Replace all uses with calls to new setter functions.
8159 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
8160 (WINDOW_INLINE): New macro.

8937 value of EMACSLOADPATH, as it is no longer needed.
8938 (check_windows_init_file): Now external, not static.
8939 Use Vload_path as is, without adding anything, as this function is now
8940 called when Vload_path is already set up.

8944 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8989 * alloc.c (record_xmalloc): New function.
8990 * lisp.h (record_xmalloc): New decl.
8991 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8992 more like a function. This is because the pointer cast is not
8993 needed. All uses changed.
8994 * print.c (print_string, print_error_message): Avoid length recalc.
8996 Improve fix for macroexp crash with debugging (Bug#12118).
8997 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8998 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8999 not supposed to be invoked from the garbage collector.

9001 (gc_aset): New function, which is like ASET but can be
9002 used in the garbage collector.

9031 with addition of handling of symlinks and support for 'lstat'.
9032 If possible, get file's attributes and security information by
9033 handle, not by name. Produce S_IFLNK bit for symlinks, when
9034 called from 'lstat'.
9035 (stat, lstat): New functions, call 'stat_worker'.
9036 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9037 symlinks when the underlying filesystem supports them.
9039 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9041 Fix macroexp crash on Windows with debugging (Bug#12118).
9042 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9043 checking subscripts; problem introduced with the recent
9044 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9045 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9046 since it's used in non-static inline functions now.
9048 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9049 Don't assume buffer size fits in 'int'. Remove unused local.

9508 2012-07-27 Michael Albinus <michael.albinus@gmx.de>
9510 * dbusbind.c (XD_DBUS_VALIDATE_BUS_ADDRESS): Canonicalize session
9512 (xd_close_bus, Fdbus_init_bus): Handle reference counter properly.
9514 2012-07-27 Eli Zaretskii <eliz@gnu.org>
9516 * alloc.c (listn): Fix the order the arguments are consed onto the
9519 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9520 enumeration constants, as PURE and HEAP are too general, and clash
9521 with other headers and sources, such as gmalloc.c and the
9522 MS-Windows system headers. All users changed.
9524 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9526 Revert last save_excursion_save and save_excursion_restore changes.
9527 * alloc.c, editfns.c, marker.c, lisp.h: Revert.
9528 Lots of crashes reported by Chong Yidong <cyd@gnu.org>.

9537 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
9539 Improve GDB symbol export (Bug#12036).
9540 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9541 arms of an 'if', not using conditional expressions; otherwise GDB
9542 complains about the types in the unevaluated arm when the argument
9543 is an integer literal.
9544 (xgetint): Simplify expression.
9545 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9546 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9547 Zaretskii in <http://bugs.gnu.org/12036#13>.
9548 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9549 needed now that we have gdb_make_enums_visible.
9550 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9551 (enum enum_USE_LSB_TAG):
9552 New enum types, packaging up enums that need to be exported to GDB.
9554 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9556 Utility function to make a list from specified amount of objects.
9557 * lisp.h (enum constype): New datatype.
9558 (listn): New prototype.
9559 * alloc.c (listn): New function.
9560 (Fmemory_use_count, syms_of_alloc): Use it.

9569 * w32fns.c (Fw32_battery_status, syms_of_w32fns): Likewise.
9570 * xdisp.c (syms_of_xdisp): Likewise.
9571 * xfns.c (syms_of_xfns): Likewise.
9573 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9575 Fast save_excursion_save and save_excursion_restore.
9576 * lisp.h (struct Lisp_Excursion): New data type.
9577 (PVEC_EXCURSION): New pseudovector type.
9578 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9579 to deal with it. Adjust comments.
9580 (init_marker, attach_marker): New prototype.
9581 (unchain_marker): Adjust prototype.
9582 * marker.c (attach_marker): Change to global.

9587 * editfns.c (save_excursion_save, save_excursion_restore):
9588 Reimplement to use struct Lisp_Excursion. Add comments.
9590 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9592 Fix export of symbols to GDB (Bug#12036).
9593 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9594 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9595 emacs.c, as this is a more-suitable home. Had this been done earlier
9596 the fix for 12036 would have avoided some of the problems noted in
9597 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9598 would have been more obvious.
9599 * emacs.c: Do not include <verify.h>; no longer needed.
9600 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9601 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9602 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9603 Remove; now done in lisp.h.
9604 * lisp.h (PUBLISH_TO_GDB): New macro.
9605 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
9606 (DATA_SEG_BITS): Use it.
9607 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9608 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9609 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9610 not be usable in #if. This simplifies things.
9612 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9614 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9616 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9618 Simplify export of symbols to GDB (Bug#12036).
9619 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9620 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9621 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9622 Adjust to changes in lisp.h and emacs.c, by using
9623 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9624 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9625 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9626 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9627 instead of gdb_valbits.
9628 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9629 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9630 instead of gdb_array_mark_flag.
9631 (xboolvector): Get size from $->size, not $->header.size.
9632 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9633 (xreload, hook-run, hookpost-run): Remove.
9634 * emacs.c: Include <verify.h>.
9635 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9636 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9638 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9639 (gdb_USE_LSB_TAG): New enum constants.
9640 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9641 Also define these as enum constants, so they're visible to GDB.
9642 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9643 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9644 as constants, so they're visible to GDB.
9645 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9646 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9647 Now enum constants, not macros, so they're visible to GDB.
9648 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9649 more convenient now. All uses changed.
9650 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9651 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9653 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
9655 Explicitly free restriction data that are not needed anymore.
9656 * editfns.c (save_restriction_restore): Free restriction data.
9658 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9660 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9661 add argument, tune behavior, and adjust all callers.
9663 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9665 Use typedef for EMACS_INT, EMACS_UINT.
9666 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9667 than macros. This simplifies debugging in the usual case, since
9668 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9669 and it allows expressions involving EMACS_INT casts.
9670 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9672 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
9674 * nsterm.m (ns_read_socket): Return early if there is a modal

9680 that FOCUS-FRAME can be omitted.
9682 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9684 Adjust buffer text indirection counters at the end of Fkill_buffer.
9685 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9686 buffer is definitely dead. This should really fix an issue reported
9687 by Christoph Scholtes again. (Bug#12007).
9688 (init_buffer_once): Initialize indirection counters of
9689 buffer_defaults and buffer_local_symbols (for sanity and safety).
9691 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9693 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9694 and continuation glyphs on tooltip frames, leave them at zero.
9695 Avoids continued lines in tooltips. (Bug#11832)
9697 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
9699 Simplify copy_overlay.
9700 * buffer.c (copy_overlay): Simplify. Use build_marker.

9706 or invalid. (Bug#12025)
9708 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
9709 it signals an error when a tooltip frame is being created.
9711 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9713 Cleanup miscellaneous objects allocation and initialization.
9714 * alloc.c (allocate_misc): Change to static. Add argument to
9715 specify the subtype. Adjust comment and users.
9716 (build_overlay): New function.
9717 * buffer.c (copy_overlays, Fmake_overlay): Use it.
9718 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.

9720 (build_overlay): Add prototype.
9722 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9724 Swap buffer text indirection counters in Fbuffer_swap_text.
9725 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9726 This avoids crash reported by Christoph Scholtes at
9727 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9729 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9731 * nsmenu.m (Popdown_data): New struct.
9732 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9734 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9735 (initWithContentRect): Make imgView and contentView non-static
9736 and autorelease them. Also autorelease img and matrix (Bug#12005).
9737 (dealloc): Remove (Bug#12005).
9739 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9741 Adjust consing_since_gc when objects are explicitly freed.
9742 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
9743 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
9744 (free_cons, free_misc): Subtract object size from consing_since_gc.
9746 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9748 Simplify and cleanup markers positioning code.

9750 (live_buffer, set_marker_internal): New function.
9751 (Fset_marker, set_marker_restricted): Use set_marker_internal.
9752 (set_marker_both, set_marker_restricted_both): Use live_buffer.
9754 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9756 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9757 as it's limited by the amount of memory, not by INT_MAX.
9759 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9761 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9762 in special-event-map. See the discussion at
9763 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
9766 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

9821 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
9822 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
9823 Adjust users accordingly.
9824 * font.h (font_open_by_name): Adjust prototype.
9826 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

9835 * bytecode.c (MAYBE_GC): Use maybe_gc.
9836 * eval.c (eval_sub, Ffuncall): Likewise.
9837 * keyboard.c (read_char): Likewise. Adjust call to maybe_gc
9838 to avoid dependency from auto-save feature.
9840 2012-07-19 Paul Eggert <eggert@cs.ucla.edu>
9842 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
9843 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
9844 'for_each_per_buffer_object_at'.
9845 All uses changed. It's better to use upper-case for macros that
9846 cannot be implemented as functions, to give the reader a clue
9847 that they're special.
9849 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
9851 * alloc.c (Fgarbage_collect): Tweak docstring.

9892 * intervals.c (merge_interval_right, merge_interval_left):
9893 Do not zero out this interval if it is absorbed by its children,
9894 as this interval's total length doesn't change in that case. See
9895 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
9897 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
9899 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
9900 when invoking (make-bool-vector N t) and N is a positive
9901 multiple of 8 -- the last 8 bits were mistakenly cleared.
9903 Remove some struct layout assumptions in bool vectors.
9904 * alloc.c (bool_header_size): New constant.
9905 (header_size, word_size): Move earlier, as they're now used earlier.
9906 Use 'word_size' in a few more places, where it's appropriate.
9907 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
9908 padding before the data member of a bool vector.
9909 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
9910 than doing the check by hand with an abort ().
9912 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9914 * eval.c (Fdefvar): Don't check constants since we only set the var if
9915 it's not yet defined anyway (bug#11904).
9917 * lisp.h (last_undo_boundary): Declare new var.
9918 * keyboard.c (command_loop_1): Set it.
9919 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
9920 were auto-added by the command loop (bug#11774).
9922 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
9924 * w32font.c (Qsymbol): Remove local definition.

10413 2012-07-11 Glenn Morris <rgm@gnu.org>
10415 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
10416 since nothing has defined it on these platforms.
10418 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
10419 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

10428 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
10430 2012-07-11 John Wiegley <johnw@newartisans.com>
10432 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
10433 function attribute, so we only use it if it exists in the
10436 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10438 Avoid call to strlen in fast_c_string_match_ignore_case.
10439 * search.c (fast_c_string_match_ignore_case): Change to use
10440 length argument. Adjust users accordingly.
10441 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
10443 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

10460 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10462 Avoid calls to strlen in font processing functions.
10463 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
10464 (font_open_by_name): Change to use length argument.

10482 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
10484 Remove "#define unix" that is no longer needed (Bug#11905).
10485 * s/aix4-2.h (unix): Remove; no longer needed.
10487 EMACS_TIME simplification (Bug#11875).
10488 This replaces macros (which typically do not work in GDB)
10489 with functions, typedefs and enums, making the code easier to debug.
10490 The functional style also makes code easier to read and maintain.
10491 * systime.h: Include <sys/time.h> on all hosts, not just if
10492 WINDOWSNT, since 'struct timeval' is needed in general.
10493 (EMACS_TIME): Now a typedef, not a macro.
10494 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
10496 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
10497 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

10501 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
10502 which are not functions. All uses rewritten to use:
10503 (make_emacs_time): New function.
10504 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
10505 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
10506 not functions. All uses rewritten to use the following, respectively:
10507 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
10508 (add_emacs_time, sub_emacs_time): New functions.
10509 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
10510 * fileio.c (Fcopy_file):
10511 * xterm.c (XTflash): Get the current time closer to when it's used.
10512 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

10517 * doc.c (Fsnarf_documentation):
10518 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
10519 * frame.c (Fmake_terminal_frame):
10520 * gtkutil.c (get_utf8_string):
10522 * nsmenu.m (ns_update_menubar):
10523 * regex.c (regerror):
10524 Prefer memcpy to strncpy and strncat when either will do.
10525 * fileio.c (Fsubstitute_in_file_name):
10526 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
10527 (menu_separator_name_p):
10528 * nsmenu.m (ns_update_menubar):
10529 Prefer memcmp to strncmp when either will do.
10530 * nsterm.m: Include <ftoastr.h>.
10532 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10533 Prefer snprintf to strncpy.
10534 * nsterm.m (ns_term_init):
10535 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10536 * nsterm.m (ns_term_init):
10537 Avoid the need for strncpy, by using build_string or
10538 make_unibyte_string directly. Use dtoastr, not snprintf.
10539 * process.c (Fmake_network_process): Diagnose service names that
10540 are too long, rather than silently truncating them or creating
10541 non-null-terminated names.
10542 (Fnetwork_interface_info): Likewise, for interface names.
10543 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10544 Prefer sprintf to strncat.
10545 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10546 Prefer vsnprintf to vsprintf + strncpy.
10548 2012-07-10 Glenn Morris <rgm@gnu.org>
10550 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
10551 Clarify fallback case.
10553 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10555 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10556 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10557 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10558 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10559 where argument type is known to be a Lisp_Cons.
10561 2012-07-10 Tom Tromey <tromey@redhat.com>
10563 * bytecode.c (BYTE_CODE_THREADED): New macro.
10564 (BYTE_CODES): New macro. Replaces all old byte-code defines.
10565 (enum byte_code_op): New type.
10566 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
10567 (exec_byte_code): Use them. Use token threading when applicable.
10569 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10571 Optimize pure C strings initialization.
10572 * lisp.h (make_pure_string): Fix prototype.
10573 (build_pure_c_string): New function, defined as static inline. This
10574 provides a better opportunity to optimize away calls to strlen when
10575 the function is called with compile-time constant argument.
10576 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10577 argument, adjust users accordingly. Use build_pure_c_string where
10579 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10580 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10581 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10583 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10585 Avoid calls to strlen in miscellaneous functions.
10586 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10587 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10588 * lread.c (openp): Likewise.
10590 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10592 Avoid calls to strlen in path processing functions.
10593 * fileio.c (file_name_as_directory): Add comment. Change to add
10594 srclen argument and return the length of result. Adjust users
10596 (directory_file_name): Fix comment. Change to add srclen argument,
10597 swap 1st and 2nd arguments to obey the common convention.
10598 Adjust users accordingly.
10599 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10601 2012-07-10 Glenn Morris <rgm@gnu.org>
10603 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
10604 Move PENDING_OUTPUT_COUNT definition to configure.
10606 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10607 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10608 * s/gnu.h (DATA_START): Move definitions to configure.
10610 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10611 We include usg5-4-common.h, which defines them both.
10613 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10614 O_RDONLY already includes it).
10616 Stop ns builds setting the EMACSLOADPATH environment variable.
10617 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10618 Now it does not set EMACSLOADPATH, just returns the load-path string.
10619 * nsterm.h: Update accordingly.
10620 * lread.c [HAVE_NS]: Include nsterm.h.
10621 (init_lread) [HAVE_NS]: Use ns_load_path.
10622 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10624 2012-07-09 Glenn Morris <rgm@gnu.org>
10626 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10627 since the included bsd-common.h does so.
10629 Stop ns builds setting the EMACSPATH environment variable.
10630 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10631 (ns_init_paths): Do not set EMACSPATH.
10632 * nsterm.h (ns_exec_path): Add it.
10633 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10636 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10638 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10640 * process.c (wait_reading_process_output): 'waitchannels' was unset
10641 when read_kbd || !NILP (wait_for_cell); fix this.
10643 Add GCC-style 'const' attribute to functions that can use it.
10644 * character.h (char_resolve_modifier_mask):
10645 * keyboard.h (make_ctrl_char):
10646 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10647 (init_character_once, next_almost_prime, init_fns, init_image)
10648 (flush_pending_output, init_sound):
10649 * mem-limits.h (start_of_data):
10650 * menu.h (finish_menu_items):
10651 Add ATTRIBUTE_CONST.
10652 * emacs.c (DEFINE_DUMMY_FUNCTION):
10653 Declare the dummy function with ATTRIBUTE_CONST.
10654 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
10655 Add decls with ATTRIBUTE_CONST.
10657 Minor improvements to make_formatted_string.
10658 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10659 where int is good enough, as vsprintf returns an int.
10660 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10662 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10664 Use make_formatted_string to avoid double length calculation.
10665 * lisp.h (make_formatted_string): New prototype.
10666 * alloc.c (make_formatted_string): New function.
10667 * buffer.c (Fgenerate_new_buffer_name): Use it.
10668 * dbusbind.c (syms_of_dbusbind): Likewise.
10669 * editfns.c (Fcurrent_time_zone): Likewise.
10670 * filelock.c (get_boot_time): Likewise.
10671 * frame.c (make_terminal_frame, set_term_frame_name)
10672 (x_report_frame_params): Likewise.
10673 * image.c (gs_load): Likewise.
10674 * minibuf.c (get_minibuffer): Likewise.
10675 * msdos.c (dos_set_window_size): Likewise.
10676 * process.c (make_process): Likewise.
10677 * xdisp.c (ensure_echo_area_buffers): Likewise.
10678 * xsettings.c (apply_xft_settings): Likewise.
10680 2012-07-09 Glenn Morris <rgm@gnu.org>
10682 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10683 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10684 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10686 * callproc.c [HAVE_NS]: Include nsterm.h.
10687 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10689 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10691 Move marker debugging code under MARKER_DEBUG.
10692 * marker.c (MARKER_DEBUG): Move marker debugging code under
10693 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10694 for bootstrap with --enable-checking (~3x slowdown reported
10695 by Juanma Barranquero <lekktu@gmail.com>).
10696 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10698 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10700 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10701 See <http://bugs.gnu.org/11825#29>.
10703 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10705 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10706 has no font, use the frame's font. (Bug#11813)
10707 (display_line): Add commentary about displaying truncation glyphs
10709 (produce_special_glyphs): Move here from term.c.
10711 * term.c (produce_special_glyphs): Move to xdisp.c.
10713 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10716 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10718 * xdisp.c (display_line): Avoid warning about implicit declaration
10721 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10723 * lisp.h: Remove empty conditional.
10725 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10727 * lread.c (load_path_check): Now static.
10729 Fix some minor --with-ns problems found by static checking.
10730 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10731 (x_set_font) [!HAVE_X_WINDOWS]:
10732 * image.c (xpm_load_image) [HAVE_NS]:
10733 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10734 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10735 Remove unused local.
10736 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10737 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10738 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10739 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10740 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10741 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10742 Fix pointer signedness problem.
10743 * xfaces.c (FRAME_X_FONT_TABLE):
10744 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10746 2012-07-07 Glenn Morris <rgm@gnu.org>
10748 * lread.c (load_path_check): New function, split from init_lread.
10749 (init_lread): Reorganize. Motivation:
10750 If EMACSLOADPATH is set, check/warn about that rather than the
10751 defaults, which we are not going to use. Hence we can remove
10752 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10753 Don't warn if site-lisp directories are missing.
10754 If not installed, start from a blank load-path, since
10755 PATH_LOADSEARCH refers to the eventual installation directories.
10757 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10759 Support truncation and continuation glyphs on GUI frames, when
10760 fringes are disabled. (Bug#11832)
10761 * xdisp.c (init_iterator): Get dimensions of truncation and
10762 continuation glyphs even if on GUI frames.
10763 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10764 or both, are absent.
10765 (start_display, move_it_in_display_line_to): Handle the case of a
10766 GUI frame without a fringe to display continuation or truncation
10768 (insert_left_trunc_glyphs): Support GUI frames: make sure
10769 truncation glyphs overwrite enough glyphs from the current line to
10770 have sufficient space in pixels.
10771 (display_line): Support truncation and continuation glyphs on GUI
10772 frames. If some spare pixels are left on the line after inserting
10773 the truncation glyphs, fill that space with a stretch glyph of a
10774 suitably computed width.
10776 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10777 produce_glyphs, to support GUI sessions.
10779 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10781 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10783 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10785 Do not require float-time's arg to fit in time_t (Bug#11825).
10786 This works better on hosts where time_t is unsigned, and where
10787 float-time is applied to the (negative) difference between two times.
10788 * editfns.c (decode_time_components): Last arg is now double *,
10789 not int *, and means to store all the result as a double, without
10790 worrying about whether the seconds part fits in time_t.
10791 All callers changed.
10792 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10793 All callers changed.
10794 (Ffloat_time): Do not fail merely because the specified time falls
10795 outside of time_t range.
10797 2012-07-07 Glenn Morris <rgm@gnu.org>
10799 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10800 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10801 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10803 2012-07-07 Juanma Barranquero <lekktu@gmail.com>

10830 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10831 Eli Zaretskii <eliz@gnu.org>
10833 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10834 Windows-specific code from nt/config.nt moved here.
10835 Obsolete settings removed.
10837 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10839 * process.c: Avoid unnecessary calls to gettime.
10840 (wait_reading_process_output): Don't get the time of day
10841 when gobbling data immediately and not waiting, as there's no need
10842 for it in that case. This removes a FIXME.
10844 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10846 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10847 is defined (Bug#11768).

10855 Call byte_char_debug_check with correct arguments.
10857 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10859 Compile marker debugging code only if ENABLE_CHECKING is defined.
10860 * marker.c (byte_char_debug_check, count_markers):
10861 Use only if ENABLE_CHECKING is defined.
10862 (byte_debug_flag): Remove.
10863 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10864 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

10894 * window.c (save_window_save): Likewise.
10896 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10898 Do not use Fdelete_overlay in delete_all_overlays
10899 to avoid redundant calls to unchain_overlay.
10900 * buffer.c (drop_overlay): New function.
10901 (delete_all_overlays, Fdelete_overlay): Use it.
10902 * minibuf.c (get_minibuffer): Fix comment.
10904 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10906 Port to OpenBSD 5.1 amd64.
10907 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10908 This is needed for OpenBSD, and should be harmless on all BSD systems.
10909 Also, include <sys/sysctl.h>, as it should be available on all
10910 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10911 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10912 use p_pid member, not kp_proc.pid.
10914 2012-07-06 Glenn Morris <rgm@gnu.org>
10916 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10918 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10920 More xmalloc and related cleanup.

10929 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10931 Omit needless casts involving void * pointers and allocation.
10932 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10933 as the former is more robust if P's type is changed.
10934 Prefer xzalloc to xmalloc + memset 0.
10935 Simplify malloc-or-realloc to realloc.
10936 Don't worry about xmalloc returning a null pointer.
10937 Prefer xstrdup to xmalloc + strcpy.

10945 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10946 hscroll is larger than the line width. Fixes long and futile
10947 looping inside extend_face_to_end_of_line (on a TTY) producing
10948 glyphs that are not needed and thrown away.
10950 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10952 * marker.c (set_marker_restricted_both): Simplify by using
10955 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10957 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10966 followed by gtk_box_set_homogeneous (Bug#11768).
10967 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10968 (update_theme_scrollbar_width, xg_create_scroll_bar):
10969 Use gtk_scrollbar_new (Bug#11768).

10971 (is_box_type): New function (Bug#11768).
10972 (xg_tool_item_stale_p): Call is_box_type.
10973 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10974 with default display (Bug#11768).
10976 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10978 * xdisp.c (window_hscroll_limited): New function.
10979 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10980 coordinates when window's hscroll is set to insanely large
10981 values. (Bug#11857)
10983 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11047 Problem reported by Troels Nielsen in
11048 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11050 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11052 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11053 This should be fixed in a better way; see Eli Zaretskii in
11054 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11055 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11057 * fileio.c (time_error_value): Rename from special_mtime.
11058 The old name's problems were noted by Eli Zaretskii in
11059 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11061 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11062 This variable's comment says Emacs needs at least one GDB-visible
11063 symbol of type enum pvec_type, to work around GDB problems.
11064 The symbol's value doesn't matter.
11066 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11067 that causes compilation to fail on pre-C99 compilers.
11069 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11071 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

11095 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11096 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11097 abusing vector->header.next.nbytes.
11098 (live_vector_p): Use PVEC_TYPE.
11099 (mark_object): Adapt code to extract pvectype. Use switch.
11101 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11103 * doprnt.c (doprnt): Don't assume string length fits in 'int'.

11108 Fix compilation with --enable-gcc-warnings and -O1
11109 optimization level.
11110 * doprnt.c (doprnt): Change type of tem to int, initialize
11111 to avoid compiler warning. Add eassert.
11112 * search.c (simple_search): Initialize match_byte to avoid
11113 compiler warning. Add eassert.
11115 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11117 Avoid weird behavior with large horizontal scrolls.
11118 Without this change, for example, large hscroll values would
11119 mess up Emacs's display on Fedora 15 x86, presumably due to
11120 overflows in int calculations in the display code.
11121 Also, if buffers had long lines, Emacs would freeze.
11122 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11123 (set_window_hscroll): New function, containing the old guts of
11124 Fset_window_hscroll. Return the clipped value.
11125 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11126 This avoids the need to check against PTRDIFF_MAX.
11128 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11130 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

11134 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11136 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11137 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11138 since GCC 4.4.6 issues a bogus warning for them.
11140 Fix bugs in file timestamp newness comparisons.
11141 * fileio.c (Ffile_newer_than_file_p):
11142 * lread.c (Fload): Use full timestamp resolution of files,
11143 not just the 1-second resolution, so that files that are only
11144 slightly newer still count as newer.
11145 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11146 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11148 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11150 * fileio.c: Improve handling of file time marker. (Bug#11852)

11160 2012-07-03 Glenn Morris <rgm@gnu.org>
11162 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11163 and did not make it into globals.h).
11165 2012-07-03 Tom Tromey <tromey@redhat.com>

11225 * alloc.c (allocate_vector_block): Remove redundant
11226 calls to mallopt if DOUG_LEA_MALLOC is defined.
11227 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11228 avoid calls to mallopt if zero_vector is returned.
11230 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11232 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11233 is enabled, avoid dereferencing NULL current_sblock if
11236 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11238 Cleanup basic buffer management.
11239 * buffer.h (struct buffer): Change layout to use generic vector

11246 (Fbuffer_local_variables): Use it.
11247 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
11248 * alloc.c (allocate_buffer): Adjust to match new layout of
11249 struct buffer. Fix comment.
11250 (mark_overlay): New function.
11251 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11252 Lisp area of struct buffer.
11253 (mark_object): Use it. Adjust marking of misc objects
11254 and related comments.
11256 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11258 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11259 wrapper that is not needed because the wrapped code is a no-op (zero
11260 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11261 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11263 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11265 * alloc.c (mark_buffer): Simplify. Remove prototype.
11266 (mark_object): Add comment. Reorganize marking of vector-like
11267 objects. Use CHECK_LIVE for all vector-like objects except buffers
11268 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11269 Avoid redundant calls to mark_vectorlike for bool vectors.
11271 2012-06-30 Glenn Morris <rgm@gnu.org>
11273 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11275 * epaths.in (PATH_SITELOADSEARCH): New.
11276 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11277 This is rather than relying on --enable-locallisppath elements
11278 having "site-lisp" in their names. (Bug#10208#25, 11658)
11280 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11282 * w32proc.c (sys_select): Accept and ignore one more argument.
11284 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11286 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11287 (pselect) [!MS_DOS]: Redirect to sys_select.
11289 * sysdep.c: Don't include dos.h and dosfns.h.
11291 * process.c (sys_select):
11292 * msdos.c (sys_select): Accept one more argument and ignore it.
11294 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11295 adapt data types and code to that.
11298 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11299 which clashes with the gnulib function of the same name.
11301 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11303 * font.c (font_style_to_value, font_style_symbolic)
11304 (font_prop_validate_style): Add type checks for values in
11307 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11309 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11312 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11314 * xdisp.c (try_window_id): Undo last change.
11316 * w32.c (getwd): Adjust commentary about startup_dir.
11317 (init_environment): Always call sys_access, even in non-MSVC
11318 builds. Don't chdir to the directory of the Emacs executable.
11319 This undoes code from 1997 which was justified by the need to
11320 "avoid conflicts when removing and renaming directories". But its
11321 downside was that every relative file name was being interpreted
11322 relative to the directory of the Emacs executable, which can never
11323 be TRT. In particular, it broke sys_access when called with
11324 relative file names.
11325 (sys_access): Map GetLastError to errno.
11327 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11330 to bitfield. Fix comment. Adjust users accordingly.
11331 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11333 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11336 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11338 * gnutls.c (emacs_gnutls_handshake):
11339 Add QUIT to make the loop interruptible.
11341 2012-06-29 Glenn Morris <rgm@gnu.org>
11343 * charset.c (init_charset): Make lack of etc/charsets fatal.
11345 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11347 * editfns.c (region_limit): Fix type mismatch.
11349 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11351 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11352 undefined. Convert from xassert to eassert.
11353 * nsmenu.m: Convert from xassert to eassert.
11354 * nsterm.m: Likewise.
11356 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

11360 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11362 Avoid integer overflow on scroll-left and scroll-right.
11363 * window.c (HSCROLL_MAX): New macro.
11364 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11365 overflow when requested scroll falls outside ptrdiff_t range.
11367 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11369 * window.h (struct window): Change type of 'hscroll',
11370 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11371 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11372 Adjust users accordingly.
11373 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11374 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11375 from EMACS_INT to ptrdiff_t.
11376 (make_window): Omit redundant initialization.

11393 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
11394 enabled with --enable-checking=[all,glyphs] configure option.
11395 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11396 adjust comments accordingly.
11397 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
11398 undefined, adjust comments accordingly.

11445 * alloc.c (allocate_string_data): Remove dead code.
11446 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
11447 avoid GCC warning about unused macro.
11449 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
11451 * alloc.c (allocate_string): Omit intervals initialization.
11452 * alloc.c (make_uninit_multibyte_string): Initialize intervals

11477 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
11478 when building with Clang.

11509 * alloc.c: Remove build_string.
11510 * lisp.h: Define build_string as static inline. This provides
11511 a better opportunity to optimize away calls to strlen when the
11512 function is called with compile-time constant argument.
11513 * image.c (imagemagick_error): Convert to build_string.
11514 * w32proc.c (sys_spawnve): Likewise.
11515 * xterm.c (x_term_init): Likewise.
11517 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11519 Use sprintf return value instead of invoking strlen on result.
11520 In the old days this wasn't portable, since some sprintf
11521 implementations returned char *. But they died out years ago and
11522 Emacs already assumes sprintf returns int.
11523 Similarly for float_to_string.
11524 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
11525 * ccl.c (ccl_driver):

11529 * print.c (print_object):
11530 * xdisp.c (message_dolog):
11531 * xfns.c (syms_of_xfns):
11532 Use sprintf or float_to_string result to avoid need to call strlen.
11533 * data.c (Fnumber_to_string):
11534 Use make_unibyte_string, since the string must be ASCII.
11535 * lisp.h, print.c (float_to_string): Now returns int length.
11536 * term.c (produce_glyphless_glyph):
11537 Use sprintf result rather than recomputing it.
11539 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11540 * Makefile.in (ALL_CFLAGS):
11541 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
11542 * gmalloc.c, regex.c: Include <config.h> unconditionally.
11544 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11546 * dispextern.h (xstrcasecmp): Define to library function
11547 strcasecmp if available.

11565 * gtkutil.c (get_utf8_string): Remove redundant assignment.
11566 sprintf already null-terminates its output.
11568 * xfns.c (x_window): Remove redundant cast.
11570 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11572 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11573 `const char *' to `char *' to avoid compiler warning.
11575 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11577 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11578 instead of truncating it to 63 (admittedly a generous limit).
11580 * process.c: Fix spelling and caps in comments.
11582 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11584 * emacs.c (setpgrp): Remove definition, unused.

11594 (SYSTIME_H): Add nt/inc/sys/time.h.
11596 * systime.h [WINDOWSNT]: Include sys/time.h.
11598 * s/ms-w32.h (struct timespec): Definition moved from
11599 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.

11629 No need for separate decl merely because of _Noreturn.
11630 * sound.c (sound_warning, parse_sound):
11631 Remove unnecessary forward decls.
11633 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11635 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
11636 * lisp.h (WAIT_READING_MAX): New macro.
11637 * dispnew.c (Fsleep_for, sit_for):
11638 * keyboard.c (kbd_buffer_get_event):
11639 * process.c (Faccept_process_output):
11640 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11641 This improves on the previous patch, which introduced a bug
11642 when time_t is unsigned and as wide as intmax_t.
11643 See <http://bugs.gnu.org/9000#51>.
11645 2012-06-23 Eli Zaretskii <eliz@gnu.org>
11647 * dispnew.c (sit_for, Fsleep_for):
11648 * keyboard.c (kbd_buffer_get_event):

11654 * makefile.w32-in: Update dependencies.
11656 * w32.c (ltime): Add return type and declare static.

11659 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
11661 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
11662 Privately reported by Herbert J. Skuhra.
11663 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
11665 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
11666 not make_lisp_timeval, when the argument is of type EMACS_TIME.
11668 2012-06-23 Eli Zaretskii <eliz@gnu.org>
11670 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
11671 last argument of make_unibyte_string.
11673 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
11674 language ID in the event parameters.
11676 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11677 event.code, not the obscure "character set ID".
11679 2012-06-23 Chong Yidong <cyd@gnu.org>
11681 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
11683 2012-06-23 Eli Zaretskii <eliz@gnu.org>
11685 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
11686 * w32.c (fdutimens): New function.
11688 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
11690 * s/ms-w32.h (pselect): Redirect to sys_select.
11692 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
11694 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
11695 in the logic of incrementing and decrementing the value of
11696 use_relocatable_buffers.
11698 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
11700 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
11701 Privately reported by Herbert J. Skuhra.
11702 [__FreeBSD__]: Remove "*/" typo after "#include".
11703 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
11704 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
11705 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
11706 Don't assume EMACS_TIME and struct timeval are the same type.
11708 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
11710 Support higher-resolution time stamps (Bug#9000).
11711 The time stamps are only nanosecond-resolution at the C level,
11712 since that's the best that any real-world system supports now.
11713 But they are picosecond-resolution at the Lisp level, as that's
11714 easy, and leaves room for future OS improvements.
11716 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11719 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11720 Don't get current time unless it's needed.
11722 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11723 now provides it if it's absent.
11724 (start_atimer): Port to higher-res time stamps.
11725 Check for time stamp overflow. Don't get current time more
11726 often than is needed.
11728 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11729 Include systime.h, not time.h.

11756 * fileio.c: Include <stat-time.h>
11757 (Fcopy_file): Copy higher-resolution time stamps.
11758 Prefer to set the time stamp via a file descriptor if that works.

11774 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
11775 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11776 Port to higher-resolution time stamps. Do not assume time_t is signed.
11777 (decode_timer): New function. Timers are now vectors of length 9,
11778 not 8, to accommodate the picosecond component.
11779 (timer_check_2): Use it.
11781 * nsterm.m (select_timeout, timeval_subtract): Remove.
11782 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11783 as they're a bit more accurate and handle overflow better.
11784 (ns_select): Change prototype to be compatible with pselect.
11785 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11786 * nsterm.h (ns_select): Adjust prototype.

11805 (Faccept_process_output, wait_reading_process_output):
11806 Check for time stamp overflow. Do not assume time_t is signed.
11807 (select_wrapper): Remove; we now use pselect.
11808 (Fprocess_attributes): Now generates ns-resolution time stamps.
11810 * sysdep.c: Include utimens.h. Don't include utime.h
11811 or worry about struct utimbuf; gnulib does that for us now.
11812 (gettimeofday): Remove; gnulib provides a substitute.
11813 (make_timeval): New function.
11814 (set_file_times): Now sets ns-resolution time stamps.
11815 New arg FD; all uses changed.

11822 provides a substitute now.
11824 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11825 since it guarantees struct timespec.
11826 (EMACS_TIME): Now struct timespec, so that we can support
11827 ns-resolution time stamps.
11828 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11829 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11830 (EMACS_USECS): Remove.
11831 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11832 so multiply the arg by 1000 before storing it.
11833 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11835 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

11842 (make_timeval, make_lisp_time, decode_time_components): New decls.
11843 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11844 that it mishandled time_t overflow. You can't compare by subtracting!
11845 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11846 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

11864 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11865 for compatibility with pselect. Support ns-resolution time stamps.

11869 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11870 Check for time stamp overflow, and support ns-resolution time stamps.

11873 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11874 (timeval_subtract): Remove; no longer needed.
11875 (XTflash, XTring_bell, x_wait_for_event):
11876 Port to ns-resolution time stamps. Don't assume time_t is signed.

11882 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11884 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11885 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11886 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11887 staticidx goes up to 1597 out of 1600 = 0x640.)
11889 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11891 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

11925 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11926 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11927 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11928 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

11935 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11937 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11938 gets killed during executing of this function (Bug#11665).
11939 Try to always return Qt when the buffer has been actually killed.
11940 (Vkill_buffer_query_functions): In doc-string say that functions
11941 run by this hook should not change the current buffer.
11943 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11945 Fix recently-introduced process.c problems found by static checking.

11965 * lisp.h (eassert): Assume C89 or later.
11966 This removes the need for CHECK.
11967 (CHECK): Remove. Its comments about always evaluating its
11968 argument were confusing, as 'eassert' typically does not evaluate
11971 * coding.c (produce_chars): Use ptrdiff_t, not int.
11973 * xterm.c (x_draw_underwave): Check for integer overflow.
11974 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

12159 code works fine either way, and efficiency is not a concern here,
12160 as the union type is for debugging, not for production.
12161 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12162 Use an inline function on all platforms when using the union type,
12163 since this is simpler and 'static inline' can be used portably
12165 (LISP_INITIALLY_ZERO): New macro.
12166 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
12167 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

12280 adjust comment accordingly.
12281 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
12282 to denote vector blocks. Adjust users (live_vector_p,

12305 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
12307 * doprnt.c (doprnt): Truncate multibyte char correctly.
12308 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12309 would mishandle a string argument "Xc" if X was a multibyte
12310 character of length 2: it would truncate after X's first byte
12311 rather than including all of X.
12313 2012-06-06 Chong Yidong <cyd@gnu.org>
12315 * buffer.c (word_wrap): Doc fix.

12362 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12364 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12365 Convert pctcpu and pctmem to Lisp float properly.
12366 Let the compiler fold better, as 100.0/0x8000 is exact.
12368 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12370 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12373 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

12377 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12379 For a 'struct window', replace some Lisp_Object fields to
12380 bitfields where appropriate, remove unused fields.
12381 * window.h (struct window): Remove unused 'last_mark_x' and
12382 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12383 change its type from Lisp_Object to bitfield.
12384 Change type of 'force_start', 'optional_new_start',
12385 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
12386 fields from Lisp_Object to bitfield. Adjust users accordingly.
12388 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12390 Pacify gcc -Wdouble-precision when using Xaw.
12391 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12392 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12393 Use 'float' consistently, rather than 'float' in most places
12394 and 'double' in a couple of places.
12396 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12398 * xdisp.c (handle_stop): Detect whether we have overlay strings
12399 loaded by testing it->current.overlay_string_index to be
12400 non-negative, instead of checking whether n_overlay_strings is
12401 positive. (Bug#11587)
12403 2012-05-31 Chong Yidong <cyd@gnu.org>
12405 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12409 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12411 * search.c (search_buffer): Remove calls to
12412 r_alloc_inhibit_buffer_relocation, as it is now called by
12413 maybe_unify_char, which was the cause of relocation of buffer text
12416 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12418 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12419 for the duration of call to load_charset, to avoid problems with
12420 callers of maybe_unify_char that access buffer text through C
12423 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12424 decrement the inhibition flag, instead of just setting or
12427 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12429 Remove obsolete '#define static' cruft.
12430 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12431 This #undef was "temporary" in 2000; it is no longer needed
12432 now that '#define static' has gone away.
12433 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12434 (gray_bitmap_bits): Remove; no longer needed.
12435 All uses replaced with definiens.

12442 * dispnew.c (__executable_start): Rename from safe_bcopy.
12443 Define only on platforms that need it.
12444 * emacs.c: Include <sys/gmon.h> when profiling.
12445 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12446 (__executable_start): Remove decl, since lisp.h does it now.
12447 (safe_bcopy): Remove decl; no longer has that name.
12448 (main): Coalesce #if into single bit of code, for simplicity.
12449 Cast pointers to uintptr_t, since standard libraries want integers
12451 * lisp.h (__executable_start): New decl.
12453 2012-05-31 Glenn Morris <rgm@gnu.org>
12455 * image.c (Fimagemagick_types): Doc fix.

12478 Do not create empty overlays with the evaporate property (Bug#9642).
12479 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12480 Bug#9642, but explicitly check that the buffer the overlay would
12481 be moved to is live and rearrange lines to make sure that errors
12482 will not put the overlay in an inconsistent state.
12483 (Fdelete_overlay): Cosmetics.
12485 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12487 * w32term.c (my_bring_window_to_top): New function.
12488 (x_raise_frame): Use handle returned by DeferWindowPos, which
12489 could be different from the original one.

12499 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12501 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12502 This avoids undefined behavior that might cause the eassert
12503 to not catch an out-of-range value.
12505 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12507 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

12521 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12522 Only r_alloc_inhibit_buffer_relocation needed to be added;
12523 the others were already declared.
12525 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12526 before checking whether it's out of range. Put the check inside
12528 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12530 2012-05-27 Ken Brown <kbrown@cornell.edu>
12532 * callproc.c (Fcall_process): Restore a line that was accidentally
12533 commented out in the 2011-02-13 change (bug#11547).

12537 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12538 defined on ralloc.c.
12540 * buffer.c [REL_ALLOC]: Remove prototypes of

12542 they are now on lisp.h.
12544 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12546 * search.c (search_buffer): Use it to inhibit relocation of buffer
12547 text while re_search_2 is doing its job, because re_search_2 is
12548 passed C pointers to buffer text. (Bug#11519)
12550 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12551 Update value to 24.
12553 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12554 state after an additional call to move_it_in_display_line_to, keep
12555 the values of it->max_ascent and it->max_descent found for the
12557 (pos_visible_p): Revert the comparison against bottom_y to what it
12558 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12561 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12563 Fix coding-related core dumps with gcc -ftrapv.
12564 The code was computing A - B, where A and B are pointers, and B is
12565 random garbage. This can lead to core dumps on platforms that
12566 have special pointer registers, and it also leads to core dumps on
12567 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12568 A - B only when B is initialized properly.
12569 * coding.c (coding_set_source, coding_set_destination): Return void.
12570 (coding_change_source, coding_change_destinations): New functions,
12571 with the old behaviors of coding_set_source and coding_set_destination.

12582 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12584 * w32console.c: Include window.h.
12585 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12587 (initialize_w32_display): Initialize mouse-highlight data.
12589 * w32inevt.c: Include termchar.h and window.h.
12590 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12591 moves, call note_mouse_highlight. If help_echo changed, call
12592 gen_help_event to produce help-echo message in the echo area.
12593 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12596 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12598 * lread.c (read1): Simplify slightly to avoid an overflow warning
12599 with GCC 4.7.0 on x86-64.
12601 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12603 * bidi.c (bidi_mirror_char): Revert last change: an int is
12604 definitely wide enough here.

12613 (make_unibyte_string, make_multibyte_string)
12614 (make_string_from_bytes, make_specified_string)
12615 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
12616 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12618 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12619 (allocate_pseudovector):

12642 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12643 (validate_region): Omit unnecessary test for b <= e,
12644 since that's guaranteed by the previous test.
12645 (adjust_overlays_for_delete): Avoid pos + length overflow.
12646 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12647 (report_overlay_modification):
12648 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12649 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12650 Omit pointer cast, which isn't needed anyway, and doesn't work
12651 after the EMACS_INT -> ptrdiff_t change.
12652 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12653 * buffer.h: Adjust decls to match defn changes elsewhere.

12658 not int, to avoid needless 32-bit limit on 64-bit hosts.
12659 (exec_byte_code): Use tighter memory-full test, one that checks
12660 for alloca overflow. Don't compute the address of the object just
12661 before an array, as that's not portable. Use EMACS_INT, not
12662 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12663 * callint.c (Fcall_interactively):
12664 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12665 * callproc.c (call_process_kill, Fcall_process):
12666 Don't assume pid_t fits into an Emacs fixnum.

12676 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12677 (casify_object): Avoid integer overflow when overallocating buffer.
12678 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12679 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12680 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12681 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12682 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

12685 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12686 For CCL_MapSingle, check that content and value are in int range.
12687 (ccl_driver, Fregister_code_conversion_map):
12688 Check that Vcode_version_map_vector is a vector.
12689 (resolve_symbol_ccl_program): Check that vector header is in range.
12690 Always copy the vector, so that we can check its contents reliably
12691 now rather than having to recheck each instruction as it's being
12692 executed. Check that vector words fit in 'int'.
12693 (ccl_get_compiled_code, Fregister_ccl_program)
12694 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12695 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

12697 contents are in range.
12698 (Fccl_execute_on_string): Check that status is in range.
12699 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12700 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12701 Accept and return EMACS_INT, not int, because callers can pass values
12702 out of 'int' range.

12708 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12709 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12710 avoid mishandling large integers.

12719 Remove now-unnecessary CHECK_NATNUMs.
12720 (Fdefine_charset_internal): Check ranges here, more carefully.
12721 Don't rely on undefined behavior with signed left shift overflow.
12722 Don't assume unsigned int fits into fixnum, or that fixnum fits
12723 into unsigned int. Don't require max_code to be a valid fixnum;
12724 that's not true for gb10830 4-byte on a 32-bit host. Allow
12725 invalid_code to be a cons, for the same reason. Require code_offset
12726 to be a character. Avoid int overflow if max_char is close
12728 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12729 this is intended anyway and avoids some undefined behavior.
12730 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12731 INDEX_TO_CODE_POINT, as that's what it expects.
12732 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12733 * charset.h (DECODE_CHAR): Return int, not unsigned;
12734 this is what was intended anyway, and it avoids undefined behavior.
12735 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12736 integer-overflow issues.
12737 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12738 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12739 where the argument is EMACS_INT, and this behavior is not intended.
12740 * chartab.c (Fmake_char_table, Fset_char_table_range)
12741 (uniprop_get_decoder, uniprop_get_encoder):
12742 Don't assume fixnum fits in int.
12743 * cmds.c (move_point): New function, that does the gist of
12744 Fforward_char and Fbackward_char, but does so while checking
12745 for integer overflow more accurately.
12746 (Fforward_char, Fbackward_char): Use it.
12747 (Fforward_line, Fend_of_line, internal_self_insert)
12748 (internal_self_insert):
12749 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13518 (Fword_search_forward, Fword_search_backward_lax)
13519 (Fword_search_forward_lax): Move functions to isearch.el

13522 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13524 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13526 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13528 * lread.c (init_obarray): Declare Qt and Qnil as special.
13530 2012-05-14 Glenn Morris <rgm@gnu.org>
13532 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13533 Put "libexec" before "bin", for the sake of init_callproc_1.
13535 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13537 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13539 * unexaix.c: Port to more-recent AIX compilers.
13540 (report_error, report_error_1, make_hdr, copy_sym)
13541 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13542 Make arguments const char *, not char *, to avoid violations of C
13543 standard and to fix some AIX warnings reported by Gilles Pion.
13545 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13547 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13548 already have overlays loaded.
13549 (handle_single_display_spec): Before returning without displaying
13550 fringe bitmap, synchronize the bidi iterator with the main display
13551 iterator, by calling iterate_out_of_display_property.
13552 (iterate_out_of_display_property): Detect buffer iteration by
13553 testing that it->string is a Lisp string.
13554 (get_next_display_element): When the current object is exhausted,
13555 and there's something on it->stack, call set_iterator_to_next to
13556 proceed with what's on the stack, instead of returning zero.
13557 (set_iterator_to_next): If called at the end of a Lisp string,
13558 proceed to consider_string_end without incrementing string
13559 position. Don't increment display vector index past the end of
13560 the display vector. (Bug#11417)
13561 (pos_visible_p): Don't report a position visible when move_it_to
13562 stopped at the last line of window, which happens to be scanned
13563 backwards by the bidi iteration. (Bug#11464)
13565 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13567 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13568 and right-margin display specs even if the spec is invalid or we
13569 are on a TTY, and thus unable to display on the fringes.
13570 That's because the text with the property will not be displayed anyway,
13571 so we need to signal to the caller that this is a "replacing"
13572 display spec. This fixes display when the spec is invalid or we
13575 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13577 * unexaix.c (make_hdr): Fix typo in prototype.
13578 This bug broke the build on AIX. Problem reported by Gilles Pion.
13580 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13582 * keyboard.c (kbd_buffer_get_event): Read special events also in
13583 batch mode. (Bug#11415)
13585 2012-05-12 Glenn Morris <rgm@gnu.org>

13589 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13591 * lisp.mk (lisp): Add newcomment.elc.
13593 2012-05-12 Glenn Morris <rgm@gnu.org>
13595 * Makefile.in (MKDIR_P): New, set by configure.
13596 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13598 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13600 Remove unused function hourglass_started.
13601 * dispextern.h (hourglass_started):

13608 Update dependencies.
13610 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13612 * xgselect.c (xg_select): Put maxfds+1 into a var.
13613 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13615 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13617 2012-05-10 Dave Abrahams <dave@boostpro.com>
13619 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13620 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13622 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13624 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13625 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13626 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13627 Initialize xd_registered_buses.
13629 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13631 Untag more efficiently if USE_LSB_TAG.
13632 This is based on a proposal by YAMAMOTO Mitsuharu in
13633 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13634 For an admittedly artificial (nth 8000 longlist) benchmark on
13635 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13636 Emacs's overall text size by 1%.
13637 * lisp.h (XUNTAG): New macro.
13638 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13639 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13640 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13641 * eval.c (Fautoload):
13642 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13643 * frame.h (XFRAME): Use XUNTAG.
13645 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13646 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13647 Remove unportable assumptions about print widths of types like
13649 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13650 intptr_t when converting between pointer and integer, to avoid GCC
13651 warnings about wrong width.
13653 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13655 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13656 stack for each reader_thread, instead of defaulting to 8MB
13657 determined by the linker. This avoids failures in creating
13658 subprocesses on Windows 7, see the discussion in this thread:
13659 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13661 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13663 Fix up display of the *Minibuf-0* buffer in the mini window.
13664 * keyboard.c (read_char): Don't clear the echo area if there's no
13666 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13667 contents of *Minibuf-0*) if there's no message displayed in its stead.
13669 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13671 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13674 2012-05-06 Chong Yidong <cyd@gnu.org>
13676 * lisp.mk (lisp): Update.
13678 2012-05-05 Jim Meyering <meyering@redhat.com>
13680 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13682 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13684 * data.c (PUT_ERROR): New macro.
13685 (syms_of_data): Use it. Add new error type `user-error'.
13686 * undo.c (user_error): New function.
13687 (Fprimitive_undo): Use it.
13688 * print.c (print_error_message): Adjust print style for `user-error'.
13689 * keyboard.c (user_error): New function.
13690 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13692 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13694 Do not limit current-time-string to years 1000..9999.
13695 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13696 (Fcurrent_time_string): Support any year that is supported by the
13697 underlying localtime representation. Don't use asctime, as it
13698 has undefined behavior for years outside the range -999..9999.
13700 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13702 Fix race conditions involving setenv, gmtime, localtime, asctime.
13703 Without this fix, interrupts could mess up code that uses these
13704 nonreentrant functions, since setting TZ invalidates existing
13705 tm_zone or tzname values, and since most of these functions return
13706 pointers to static storage.
13707 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13708 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13709 Grow the critical sections to include not just invoking
13710 localtime/gmtime, but also accessing these functions' results
13711 including their tm_zone values if any, and any related TZ setting.
13712 (format_time_string): Last arg is now struct tm *, not struct tm **,
13713 so that the struct tm is saved in the critical section.
13714 All callers changed. Simplify allocation of initial buffer, partly
13715 motivated by the fact that memory allocation needs to be outside
13716 the critical section.
13718 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13720 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13721 with RESET_INTERVAL.
13723 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13724 Remove duplicated buffer name initialization.
13726 2012-05-02 Jim Meyering <jim@meyering.net>
13728 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13730 * xfns.c (x_window): Use xstrdup (Bug#11375).
13732 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13734 * xdisp.c (pos_visible_p): If already at a newline from the
13735 display string before the 'while' loop, don't walk back the glyphs
13736 from it3.glyph_row. Solves assertion violation when the display
13737 string begins with a newline (egg.el). (Bug#11367)
13739 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13741 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13744 2012-05-01 Glenn Morris <rgm@gnu.org>

13747 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13748 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13749 All were removed before 23.1.
13751 * dispnew.c: Remove HAVE_LIBNCURSES test;
13752 it is always true on relevant platforms.
13754 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13755 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13757 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13759 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13761 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13762 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13765 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13767 Do not avoid creating empty evaporating overlays (Bug#9642).
13768 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13769 That is, do not delete an evaporating overlay if it becomes
13770 empty after its bounds are adjusted to fit within its buffer.
13771 This fix caused other problems, and I'm reverting it until we get
13772 to the bottom of them.
13774 2012-04-27 Chong Yidong <cyd@gnu.org>
13776 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13778 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13780 * xdisp.c (pos_visible_p): If the window start position is beyond
13781 ZV, start the display from buffer beginning. Prevents assertion
13782 violation in init_iterator when the minibuffer window is scrolled
13783 via the scroll bar.
13785 * window.c (window_scroll_pixel_based): Likewise.
13787 2012-04-27 Chong Yidong <cyd@gnu.org>
13789 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13791 2012-04-27 Glenn Morris <rgm@gnu.org>
13793 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13794 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13796 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13798 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13799 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13801 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13803 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13804 display element, check also the underlying string or buffer
13805 character. (Bug#11341)
13807 * w32menu.c: Include w32heap.h.
13808 (add_menu_item): If the call to AppendMenuW (via
13809 unicode_append_menu) fails, disable Unicode menus only if we are
13810 running on Windows 9X/Me.
13812 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13814 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13815 (xgetint): Add missing shift for LSB tags.
13817 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13819 * keyboard.c (read_char): Don't wipe echo area for select window
13820 events: These might get delayed via `mouse-autoselect-window'
13823 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13825 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13826 manipulation of :loaded-from data.
13828 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13830 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13831 now a cons (bug#11311).
13833 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13835 Do not create empty overlays with the evaporate property (Bug#9642).
13836 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13837 if it becomes empty after its bounds are adjusted to fit within
13838 its buffer. Without this fix, in a nonempty buffer (let ((o
13839 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13840 yields an empty overlay that has the evaporate property, which is
13841 not supposed to happen.
13843 Fix minor GTK3 problems found by static checking.
13844 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

13863 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13864 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13865 (__malloc_size_t, __malloc_ptrdiff_t):
13866 Remove. All uses removed, replaced by the definiens if needed,
13867 since we can assume C89 or better now.
13868 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

13876 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13877 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):

14053 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
14054 (r_alloc_sbrk): Now static.
14056 Improve ralloc.c interface checking.
14057 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html

14087 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14088 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14089 no longer the default.
14090 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14092 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

14117 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14118 against is gone. It's better to use vfork now so that when Cygwin
14119 gains a new, working vfork, we use it automatically (bug#10398).
14121 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
14123 * window.c (save_window_save): Obey window-point-insertion-type.

14135 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
14136 (force_quit_count): New var.
14137 (handle_interrupt): Use it.
14139 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
14141 * w32.c (w32_delayed_load): Record the full path of the library
14142 being loaded (bug#10424).
14144 2012-04-09 Glenn Morris <rgm@gnu.org>
14146 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14147 not just in the obarray, before snarfing them. (Bug#11036)
14149 * Makefile.in ($(leimdir)/leim-list.el):
14150 Pass EMACS rather than BUILT_EMACS.
14152 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
14154 * process.c (make_process):
14155 * process.h: Add integer `gnutls_handshakes_tried' member to
14158 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
14159 Add convenience `GNUTLS_LOG2i' macro.
14161 * gnutls.c (gnutls_log_function2i): Convenience log function.
14162 (emacs_gnutls_read): Use new log functions,
14163 `gnutls_handshakes_tried' process member, and
14164 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14165 attempts per process (connection).
14167 2012-04-09 Chong Yidong <cyd@gnu.org>
14169 * eval.c (Fuser_variable_p, user_variable_p_eh)
14170 (lisp_indirect_variable): Functions deleted.
14171 (Fdefvar): Caller changed.
14173 * callint.c (Finteractive, Fcall_interactively):
14174 * minibuf.c (Fread_variable): Callers changed.
14176 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14178 * xdisp.c (set_cursor_from_row): If the display string appears in
14179 the buffer at position that is closer to point than the position
14180 after the display string, display the cursor on the first glyph of
14181 the display string. Fixes cursor display when a 'display' text
14182 property immediately follows invisible text. (Bug#11094)
14184 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14186 composite.c: use 'double' consistently
14187 * composite.c (get_composition_id): Use 'double' consistently
14188 instead of converting 'float' to 'double' and vice versa; this is
14189 easier to understand and avoids a GCC warning.
14191 2012-04-09 Glenn Morris <rgm@gnu.org>
14193 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14194 preparation for dumping it with emacs. (Bug#4789)
14195 (leimdir): New variable.
14196 ($(leimdir)/leim-list.el): New rule.
14197 (emacs$(EXEEXT)): Depend on leim-list.el.
14199 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
14200 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
14201 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
14203 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>

14210 * xml.c (init_libxml2_functions) [WINDOWSNT]:
14211 Remove unused local variable.
14213 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
14215 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14216 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14217 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14218 objects, as mark_maybe_pointer will catch them otherwise.
14219 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
14220 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
14222 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
14224 Fix typo that broke non-Windows builds.
14225 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
14227 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14229 Support building on MS-Windows with libxml2.
14231 * makefile.w32-in (OBJ2): Add xml.$(O).
14232 (GLOBAL_SOURCES): Add xml.c.
14233 ($(BLD)/xml.$(O)): New dependency list.
14235 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14236 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14237 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14238 [!WINDOWSNT]: New macros.
14239 (init_libxml2_functions, libxml2_loaded_p): New functions.
14240 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14241 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14242 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14243 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14245 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14246 Call init_libxml2_functions before calling libxml2 functions.
14247 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14249 * emacs.c: Don't include libxml/parser.h.
14250 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14251 xmlCleanupParser directly.
14253 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14255 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14257 * indent.c (Fvertical_motion): If there is a display string at
14258 point, use it.vpos to compute how many lines to backtrack after
14259 move_it_to point. (Bug#11133)
14261 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14263 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14264 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14265 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14266 macros related to unification of CJK characters. For the details,
14267 see the discussion following the message here:
14268 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14270 2012-04-04 Chong Yidong <cyd@gnu.org>
14272 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14274 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14276 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
14277 instead of alloca. (Bug#11138)
14279 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
14281 * w32menu.c (is_simple_dialog): Properly check lisp types.
14284 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14286 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14287 position we get to after a call to move_it_to fails the
14288 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14289 only if we wind up in a string from display property. (Bug#11063)
14291 * window.c (Fdelete_other_windows_internal): Invalidate the row
14292 and column information about mouse highlight, so that redisplay
14293 restores it after reallocating the glyph matrices. (Bug#7464)
14295 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14296 string comes from a `display' text property, use the buffer
14297 position of that property as if we actually saw that position in
14299 (move_it_by_lines): Remove the assertion that
14300 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14301 violated when there's a before-string at the beginning of a line.
14304 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14306 * xdisp.c (append_space_for_newline): If the default face was
14307 remapped, use the remapped face for the appended newline.
14308 (extend_face_to_end_of_line): Use the remapped default face for
14309 extending the face to the end of the line.
14310 (display_line): Call extend_face_to_end_of_line when the default
14311 face was remapped. (Bug#11068)
14313 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14315 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14317 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14319 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
14321 2012-03-27 Glenn Morris <rgm@gnu.org>
14323 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
14326 2012-03-26 Kenichi Handa <handa@m17n.org>
14328 * dispextern.h (struct glyph): Fix previous change. Change the
14329 bit length of glyphless.ch to 25 (Bug#11082).
14331 2012-03-26 Chong Yidong <cyd@gnu.org>
14333 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14334 (command_loop_1): Use it; inhibit selection update for
14335 handle-select-window too (Bug#8996).
14337 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
14339 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14341 2012-03-25 Kenichi Handa <handa@m17n.org>
14343 * dispextern.h (struct glyph): Change the bit length of
14344 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14346 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14348 * s/ms-w32.h (tzname): Include time.h before redirecting to
14349 _tzname. Fixes the MSVC build. (Bug#9960)
14351 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
14353 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14356 * xterm.c (XTread_socket): Only modify handling_signal if
14357 !SYNC_INPUT. (Bug#11080)
14359 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14361 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14362 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14363 when fetching a multibyte character consumes more bytes than
14364 CHAR_BYTES returns, due to unification of CJK characters in
14365 string_char. (Bug#11073)
14367 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14369 * process.c (wait_reading_process_output): Handle pty disconnect
14370 by refraining from sending oneself a SIGCHLD (bug#10933).
14372 2012-03-22 Chong Yidong <cyd@gnu.org>
14374 * dispextern.h (struct it): New member string_from_prefix_prop_p.
14376 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
14377 Mark string as coming from a prefix property.
14378 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14379 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14381 2012-03-21 Chong Yidong <cyd@gnu.org>
14383 * xfaces.c (Vface_remapping_alist): Doc fix.
14385 2012-03-20 Eli Zaretskii <eliz@gnu.org>
14387 * w32proc.c (Fw32_set_console_codepage)
14388 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
14391 2012-03-20 Chong Yidong <cyd@gnu.org>
14393 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
14394 to reflect default non-nil value of redisplay-dont-pause.
14396 2012-03-19 Kenichi Handa <handa@m17n.org>
14398 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
14399 it fit in a valid range (Bug#11003).
14401 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14403 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14404 that is not from display property, accept the row as a "cursor
14405 row" if one of the string's character has a non-nil `cursor'
14406 property. Fixes cursor positioning when there are newlines in
14407 overlay strings, e.g. in icomplete.el. (Bug#11035)
14409 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14411 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14413 2012-03-12 Chong Yidong <cyd@gnu.org>
14415 * eval.c (inhibit_lisp_code): Rename from
14416 inhibit_window_configuration_change_hook; move from window.c.
14418 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14419 * window.c (run_window_configuration_change_hook)
14420 (syms_of_window): Callers changed.
14422 2012-03-11 Chong Yidong <cyd@gnu.org>
14424 * keymap.c (Fkey_description): Doc fix (Bug#9700).
14426 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
14428 2012-03-10 Chong Yidong <cyd@gnu.org>
14430 * frame.c (other_visible_frames): Don't assume the selected frame
14431 is visible (Bug#10955).
14433 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
14435 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14437 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14439 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14440 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14443 2012-03-03 Glenn Morris <rgm@gnu.org>
14445 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14447 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14449 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14450 position past the first glyph_row that ends at ZV. (Bug#10902)
14451 (redisplay_window, next_element_from_string): Fix typos in
14453 (redisplay_window): Pass to move_it_vertically the margin in
14454 pixels, not in screen lines.
14456 2012-03-02 Glenn Morris <rgm@gnu.org>
14458 * buffer.c (buffer-list-update-hook): Doc fix.
14460 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14462 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14463 push_it before setting up the iterator for the first overlay
14464 string, even if we have an empty string loaded.
14465 (next_overlay_string): If there's an empty string on the iterator
14466 stack, pop the stack. (Bug#10903)
14468 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14470 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14471 Suggested by Stefan Monnier in
14472 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14473 * alloc.c (widen_to_Lisp_Object): New static function.
14474 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14475 and widening them to Lisp_Objects. This would work even if
14476 USE_LSB_TAG is defined and wide integers are used, which might
14477 happen in a future version of Emacs.
14479 2012-02-25 Chong Yidong <cyd@gnu.org>
14481 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14484 * xselect.c (Fx_selection_exists_p): Doc fix.
14485 (x_clipboard_manager_save_all): Print an informative message
14486 before saving to clipboard manager.
14488 2012-02-24 Chong Yidong <cyd@gnu.org>
14490 * keyboard.c (process_special_events): Handle all X selection
14491 requests in kbd_buffer, not just the next one (Bug#8869).
14493 2012-02-23 Chong Yidong <cyd@gnu.org>
14495 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14496 call when setting menu-bar-lines and tool-bar-lines parameters.
14497 (unwind_create_frame_1): New helper function.
14499 * window.c (inhibit_window_configuration_change_hook): New var.
14500 (run_window_configuration_change_hook): Obey it.
14501 (syms_of_window): Initialize it.
14503 2012-02-22 Chong Yidong <cyd@gnu.org>
14505 * xterm.c (x_draw_image_relief): Add missing type check for
14506 Vtool_bar_button_margin (Bug#10743).
14508 2012-02-21 Chong Yidong <cyd@gnu.org>
14510 * fileio.c (Vfile_name_handler_alist): Doc fix.
14512 * buffer.c (Fget_file_buffer): Protect against invalid file
14513 handler return value.
14515 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
14517 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
14518 when computing $valmask.
14520 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14521 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14522 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14523 It's useless in that case, and it can cause problems on hosts
14524 that allocate halves of EMACS_INT values separately.
14525 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14526 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14527 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14528 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14529 it avoids undefined behavior on hosts where shifting right by more
14530 than the word width has undefined behavior.
14532 2012-02-19 Chong Yidong <cyd@gnu.org>
14534 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14535 (Funhandled_file_name_directory, Ffile_name_as_directory)
14536 (Fdirectory_file_name, Fexpand_file_name)
14537 (Fsubstitute_in_file_name): Protect against invalid file handler
14538 return values (Bug#10845).
14540 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14542 * .gdbinit (pitx): Fix incorrect references to fields of the
14545 2012-02-17 Chong Yidong <cyd@gnu.org>
14547 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
14549 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
14551 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
14552 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14554 2012-02-15 Chong Yidong <cyd@gnu.org>
14556 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14557 marked as special. Also, starting docstrings with * is obsolete.
14559 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
14561 * gnutls.c (emacs_gnutls_write): Fix last change.
14563 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
14565 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
14568 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
14570 * keymap.c (Fsingle_key_description): Handle char ranges.
14572 2012-02-12 Chong Yidong <cyd@gnu.org>
14574 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14575 as that creates a dangerous corner case.
14577 * window.c (Fdelete_window_internal): Invalidate the mouse
14578 highlight (Bug#9904).
14580 2012-02-12 Glenn Morris <rgm@gnu.org>
14582 * xselect.c (Fx_own_selection_internal)
14583 (Fx_get_selection_internal, Fx_disown_selection_internal)
14584 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
14585 * nsselect.m (Fx_own_selection_internal)
14586 (Fx_disown_selection_internal, Fx_selection_exists_p)
14587 (Fx_selection_owner_p, Fx_get_selection_internal):
14588 Sync docs and argument specs with the xselect.c versions.

15147 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
15148 verifies glyph row's hash code--we have just reallocated the
15149 glyphs, so their contents can be complete garbage. (Bug#10164)

15313 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15314 is set, removing the need for VIRT_ADDRESS_VARIES.
15315 (PURE_P): Use a more-efficient implementation that needs just one
15316 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
15317 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
15318 to 4 (xorl, subq, cmpq, setbe).
15319 * alloc.c (pure): Always extern now, since that's the

15322 consistency with the new puresize.h.
15323 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
15324 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

15330 (erase_phys_cursor, update_window_cursor, show_mouse_face)
15331 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
15332 behave as if the cursor position were at the window margin.
15334 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15335 and the cursor position is out of bounds, behave as if the cursor
15336 position were at the window margin. (Bug#10075)
15338 2011-11-18 Chong Yidong <cyd@gnu.org>
15340 * window.c (Fwindow_combination_limit): Make first argument

15359 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
15361 * xdisp.c (row_hash): New function, body extracted from
15362 compute_line_metrics.
15363 (compute_line_metrics): Call row_hash, instead of computing the
15366 * dispnew.c (verify_row_hash): Call row_hash for computing the
15367 hash code of a row, instead of duplicating code from xdisp.c.
15369 * dispextern.h (row_hash): Add prototype.
15371 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
15373 * frame.c (delete_frame): Don't delete the terminal when the last

15409 * xdisp.c (display_line): Move the call to
15410 highlight_trailing_whitespace before the call to
15411 compute_line_metrics, since the latter needs to see the final
15412 faces of all the glyphs to compute ROW's hash value.

15422 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
15423 with user-defined heap size. Bump the default size of the temacs

15427 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15428 current_matrix and desired_matrix. (Bug#9990)
15429 (verify_row_hash) [XASSERTS]: New function.

15474 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
15476 Avoid some portability problems by eschewing 'extern inline' functions.
15477 The trivial performance wins aren't worth the portability hassles; see
15478 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15480 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

15546 * xmenu.c (cleanup_widget_value_tree): New function.
15547 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15548 calling free_menubar_widget_value_tree directly (Bug#9830).
15550 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
15552 Fix some portability problems with 'inline'.
15553 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
15554 (window_box_width, window_box_left, window_box_left_offset)
15555 (window_box_right, window_box_right_offset): Declare extern.
15556 Otherwise, these inline functions do not conform to C99 and
15557 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15558 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15559 * intervals.c (adjust_intervals_for_insertion)
15560 (adjust_intervals_for_deletion): Now extern, because otherwise the
15561 extern inline functions 'offset_intervals' couldn't refer to it.
15562 (static_offset_intervals): Remove.
15563 (offset_intervals): Rewrite using the old contents of
15564 static_offset_intervals. The old version didn't conform to C99
15565 because an extern inline function contained a reference to an
15566 identifier with static linkage.
15568 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
15570 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

15577 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
15578 return Qleft_to_right.

15588 (Fwindow_vscroll): Doc fix.
15589 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
15590 argument, since it makes no sense to pass a live window and for
15591 consistency with window-child.

15619 (unwind_create_frame): New function (Bug#9943).
15620 (Fx_create_frame): Restructure code to be more similar to the one in
15621 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
15622 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
15623 Move terminal->reference_count++ just before making the frame official

15631 Move terminal->reference_count++ just before making the frame
15632 official. Move initialization of image_cache_refcount and
15633 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15672 * xdisp.c (note_mouse_highlight): If either of
15673 previous/next-single-property-change returns nil, treat that as
15674 the beginning or the end of the buffer. (Bug#9955)
15676 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
15678 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

15710 2011-10-30 Eli Zaretskii <eliz@gnu.org>
15712 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
15713 past the beginning of the current glyph matrix.
15715 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
15717 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

15761 2011-10-29 Glenn Morris <rgm@gnu.org>
15763 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
15764 Not clear what it was for, and it causes various bugs. (Bug#9839)
15766 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15768 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

15770 condition to clear the mouse face.
15772 2011-10-28 Chong Yidong <cyd@gnu.org>

15788 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15790 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
15791 <oslsachem@gmail.com> for helping to debug this.

15801 (w32font_open_internal, compute_metrics):
15802 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15803 instead of calling the "wide" APIs directly.
15805 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15807 * w32.h (syms_of_w32font): Add prototype.
15809 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15811 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)

15813 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15814 (Fmove_to_window_line): Doc fix.
15816 2011-10-27 Chong Yidong <cyd@gnu.org>
15818 * process.c (make_process): Set gnutls_state to NULL.
15820 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15821 non-NULL, regardless of GNUTLS_INITSTAGE.
15822 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

15849 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15851 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).

15870 (bidi_resolve_weak): Don't enter the expensive loop if the current
15871 position is before next_en_pos. Record the bidi type of the first
15872 non-ET, non-BN character we find, in addition to its position.
15873 (bidi_level_of_next_char): Invalidate next_en_type when
15874 next_en_pos is over-stepped.
15876 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15878 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15879 * editfns.c: Rewrite current-time-zone so that it invokes
15880 the equivalent of (format-time-string "%Z") to get the time zone name.
15881 This fixes a bug when the time zone name contains characters that
15882 need converting from the system time locale to Emacs internal format.
15883 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15884 that patch fixed format-time-string to do the conversion, but
15885 I forgot to fix current-time-zone.
15886 (format_time_string): New function, containing most of
15887 what Fformat_time_string used to contain.
15888 (Fformat_time_string): Rewrite in terms of format_time_string.
15889 This doesn't change this function's behavior.
15890 (current-time-zone): Rewrite to use format_time_string.
15891 This fixes the bug reported by Michael Schierl in
15892 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15893 Jason Rumney's 2007-06-07 change worked around this bug, but
15895 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15897 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15899 * xdisp.c (start_display): If the character at POS is displayed
15900 via a display vector, reset IT->current.dpvec_index to zero.
15901 (try_window_reusing_current_matrix): If a line ends in a display
15902 vector or the next line starts in a display vector, continue
15903 redrawing the window even though the character position of
15904 start_row was reached.
15907 2011-10-18 Chong Yidong <cyd@gnu.org>
15909 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15910 with nobreak-char-display too.
15912 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15914 Fix part 3 of bug#9771.
15915 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15916 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15917 non-neutral characters if the current character is a paragraph
15918 separator (a.k.a. Newline). This avoids running the same
15919 expensive loop twice, once when we consume the preceding newline
15920 and the other time when the line actually needs to be displayed.
15921 Avoid the loop when we see neutrals on the base embedding level
15922 following a character whose directionality is the same as the
15923 paragraph's. This avoids running the expensive loop when a line
15924 ends in a long sequence of neutrals, like control characters.
15925 Add assertion against STRONG_AL type. Slightly rearrange code
15926 that determines the type of a neutral given the first non-neutral
15928 (bidi_level_of_next_char): Set next_en_pos to zero when
15929 invalidating its info.
15931 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15933 * xdisp.c (push_display_prop): Determine whether to record string
15934 or buffer position by IT->string, not by IT->method. Allow
15935 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15936 (move_it_vertically_backward): Don't look for character position
15937 immediately after the newline when in a continuation line.
15940 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15942 * window.c (coordinates_in_window): Rewrite and delabelize
15943 vertical border check. (Bug#5357) (Bug#9618)
15945 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15947 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15948 errors in XSetWindowBorder (bug#9310).
15950 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15952 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15953 avoid crash when xmalloc overrun checking is enabled.
15955 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15957 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15958 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15959 cursor motion with <left> and <right> arrow keys.
15961 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15962 some callers set that themselves.
15964 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15966 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15967 display string and the previous row comes from the same string and
15968 is empty. (Bug#9739) (Bug#9738)
15970 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15972 * doc.c (get_doc_string): Encode file name (bug#9735).
15974 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15976 * bidi.c (bidi_level_of_next_char):
15977 * xdisp.c (get_visually_first_element): Remove old incorrect
15978 comments regarding the Unicode Line Separator character.
15980 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15982 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>

15985 boundary if nzombies > MAX_ZOMBIES.
15986 * alloc.c (dump_zombies): Add missing format specifier.
15988 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15990 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15991 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15993 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15994 Some packages use them to denote characters with modifiers.
15996 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15998 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15999 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16000 matching a pp-number. Rename parameter var to var1.
16002 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16004 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16006 2011-10-08 Glenn Morris <rgm@gnu.org>
16008 * callint.c (Fcall_interactively): Give a more explicit error for the
16009 'c' case with a non-character input. (Bug#8479)
16011 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16013 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16015 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16016 lines that are hscrolled on the left.
16018 * dispnew.c (buffer_posn_from_coords): Account for a possible
16019 presence of header-line. (Bug#4426)
16021 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16023 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16024 Don't advertise functionality which we discourage or doesn't work.
16026 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16028 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16029 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16030 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16031 this makes Emacs dump core during garbage collection on rare
16032 occasions. sizeof is obviously inferior to offsetof here, so
16033 stick with offsetof.
16034 (GC_POINTER_ALIGNMENT): New macro.
16035 (mark_memory): Omit 3rd (offset) arg; caller changed.
16036 Don't assume EMACS_INT alignment is the same as pointer alignment.
16038 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16040 * keyboard.c (read_key_sequence_remapped): New var.
16041 (read_key_sequence): Compute remapping in the right buffer.
16042 (command_loop_1): Use read_key_sequence's remapping directly.
16044 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16046 * dired.c (file_name_completion): Don't expand file name.
16047 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16048 before checking file name handler.
16050 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16051 they've been requested explicitly (bug#9591).
16053 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16055 * keymap.c (Fsingle_key_description): Use make_specified_string
16056 instead of build_string to build string from push_key_description.
16059 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16061 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16062 This fixes a Y2038 bug on 64-bit hosts.
16063 * buffer.c (reset_buffer):
16064 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16065 (Fclear_buffer_auto_save_failure):
16066 Use 0, not -1, to represent an unset failure time, since time_t
16067 might not be signed.
16069 Remove dependency on glibc malloc internals.
16070 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16071 Move back here from lisp.h, but with their new implementations.
16072 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16073 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16074 * charset.c (charset_table_init): New static var.
16075 (syms_of_charset): Use it instead of xmalloc. This removes a
16076 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16077 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16078 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16079 Move back to alloc.c.
16080 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16081 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16083 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16085 * nsterm.m (windowDidResize): Call x_set_window_size only when
16086 ns_in_resize is true. Otherwise set pixelwidth/height and
16087 call change_frame_size (Bug#9628).
16089 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16091 Port --enable-checking=all to Fedora 14 x86-64.
16092 * charset.c (syms_of_charset): Also account for glibc malloc's
16093 internal overhead when calculating the initial malloc maximum.
16095 Port --enable-checking=all to Fedora 14 x86.
16096 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16098 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16099 (overrun_check_realloc, overrun_check_free):
16100 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16101 That way, xmalloc returns a properly-aligned pointer even if
16102 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16103 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16104 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16105 into account when calculating the initial malloc maximum.
16106 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16107 Move here from alloc.c, so that charset.c can use it too.
16108 Properly align; the old code wasn't right for common 32-bit hosts
16109 when configured with --enable-checking=all.
16110 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16111 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16113 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16115 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16118 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16120 * xdisp.c (compute_display_string_end): If there's no display
16121 string at CHARPOS, return -1.
16123 * bidi.c (bidi_fetch_char): When compute_display_string_end
16124 returns a negative value, treat the character as a normal
16125 character not covered by a display string. (Bug#9624)
16127 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16129 * lread.c (Fread_from_string): Fix typo in docstring.
16131 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16133 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16134 newline, reseat the iterator instead of bidi-iterating there one
16135 character at a time. (Bug#9610)
16136 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16137 TO_CHARPOS if the bidi iterator is at base embedding level.
16139 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16141 * lread.c (readevalloop): Use correct code for NBSP.
16142 (read1): Likewise. (Bug#9608)
16144 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16146 * dbusbind.c (Fdbus_register_signal): When service is not
16147 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16149 2011-09-25 Glenn Morris <rgm@gnu.org>
16151 * buffer.c (truncate-lines): Doc fix.
16153 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16155 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16156 (Fset_window_next_buffers): Doc fix.
16158 2011-09-24 Glenn Morris <rgm@gnu.org>
16160 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16162 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16164 Fix minor problems found by static checking.
16165 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16166 * indent.c (Fvertical_motion): Fix == vs = typo.
16168 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16170 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16171 Default value is now t. Doc fix.
16173 * indent.c (Fvertical_motion): Compute and apply the overshoot
16174 logic when moving up, not only when moving down. Fix the
16175 confusing name and values of the it_overshoot_expected variable;
16176 logic changes accordingly. (Bug#9254) (Bug#9549)
16178 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16179 CHARPOS is covered by a display string which includes newlines.
16180 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16181 is covered by a display string with embedded newlines.
16183 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16185 * dbusbind.c (Fdbus_register_signal): Add match rule to
16186 Vdbus_registered_objects_table. (Bug#9581)
16187 (Fdbus_register_method, Vdbus_registered_objects_table):
16190 2011-09-24 Jim Meyering <meyering@redhat.com>
16192 do not ignore write error for any output size
16193 The previous change was incomplete.
16194 While it makes emacs --batch detect the vast majority of stdout
16195 write failures, errors were still ignored whenever the output size is
16196 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16197 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16198 && echo FAIL: ignored write error
16199 FAIL: ignored write error
16200 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16201 && echo FAIL: ignored write error
16202 FAIL: ignored write error
16203 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16205 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16207 * emacs.c (Fkill_emacs): In noninteractive mode exit
16208 non-successfully if a write error occurred on stdout. (Bug#9574)
16210 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16212 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16215 * dispextern.h (struct it): Update the comment documenting what
16218 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16220 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16221 a display string, extend search for cursor position to end of row.
16222 (find_row_edges): If the row ends in a newline from a display
16223 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16224 Handle the case of a display string with multiple newlines.
16225 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16226 non-empty line. Fixes confusing cursor motion with arrow keys at
16227 the beginning of a line that starts with whitespace.
16229 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16231 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16234 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16236 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16237 boolean (Bug#9154).
16239 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16241 * xdisp.c (display_line): Record maximum and minimum buffer
16242 positions even if no glyphs were produced (e.g., by a zero-width
16243 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16244 buffer positions that will be removed from the glyph row because
16246 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16247 column is beyond frame width: don't subtract 1 "pixel" when
16248 computing width of the stretch.
16249 (reseat_at_next_visible_line_start): Undo the change made on
16250 2011-09-17 that saved paragraph information and restored it after
16251 the call to `reseat'. (Bug#9545)
16253 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16255 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16256 and turn window cursor on if cleared (Bug#9415).
16258 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16260 * search.c (boyer_moore): Take unibyte characters from pattern
16261 literally. (Bug#9458)
16263 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16265 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16267 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16269 Fix minor problem found by static checking.
16270 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16271 initialized, to pacify gcc -Wuninitialized.
16273 * fileio.c: Report proper errno when syscall falls.
16274 (Finsert_file_contents): Save and restore errno,
16275 so that report_file_error outputs the correct diagnostic.
16276 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16278 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16280 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16282 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16284 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16285 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16287 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16289 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16290 about the current paragraph and restore it after the call to reseat.
16292 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16293 (bidi_find_paragraph_start): Search back for paragraph beginning
16294 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16295 (bidi_move_to_visually_next): Only trigger paragraph-related
16296 computations when the last character is a newline or at EOB, not
16297 just any NEUTRAL_B. (Bug#9470)
16299 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16300 truncated lines if point is covered by a display string. (Bug#9524)
16302 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16304 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16305 (cons_to_x_long): New function.
16306 (lisp_data_to_selection_data): Use it. Correct the test for
16307 short-versus-long data; it was negated. Break out of vector
16308 loop, for efficiency, when a long datum is discovered.
16310 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16312 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16314 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16316 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16317 GCC PR/17406) by declaring this function with external scope.
16319 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16321 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16322 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16324 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16326 * editfns.c (Fformat): Correctly handle text properties on "%%".
16328 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16330 * xterm.c (x_draw_composite_glyph_string_foreground):
16331 * w32term.c (x_draw_composite_glyph_string_foreground):
16332 * term.c (encode_terminal_code):
16333 * composite.c (composition_update_it, get_composition_id):
16334 * xdisp.c (get_next_display_element)
16335 (fill_composite_glyph_string): Add comments about special meaning
16336 of TAB characters in a composition.
16338 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16340 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16341 This occurs when processing a multibyte format.
16342 Problem reported by Wolfgang Jenker.
16344 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16346 * xdisp.c (try_cursor_movement): Only check for exact match if
16347 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16349 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16351 Remove unused external symbols.
16352 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16353 * xdisp.c (calc_pixel_width_or_height): Now static.
16354 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16355 * indent.c (check_display_width):
16356 * w32term.c: Fix comment to match code.
16357 * xterm.c, xterm.h (x_catching_errors): Remove.
16359 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16361 * xselect.c: Use signed conversions more consistently (Bug#9498).
16362 (selection_data_to_lisp_data): Assume incoming selection data are
16363 signed integers, not unsigned. This is to be consistent with
16364 outgoing selection data, which was modified to use signed integers
16365 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16366 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16367 expects long, not unsigned long.
16369 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16371 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16372 computation of loop end. Reported by Johan Bockgård
16375 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16377 * frame.c (Fother_visible_frames_p): Function deleted.
16379 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16381 * indent.c (compute_motion): Process display vector front to back
16382 rather than the other way around. (Bug#2496)
16384 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16386 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16388 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16390 * minibuf.c (Fread_from_minibuffer): Doc fix.
16392 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16394 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16395 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16397 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16399 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16400 value for non-existent files.
16402 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16404 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16405 set its "size" to -1. This will set the modtime_size field of
16406 the corresponding buffer to -1, which is what
16407 verify-visited-file-modtime expects for files that do not exist.
16410 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16412 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16414 * lisp.h: ... from here. push_key_description is no longer
16415 defined in keyboard.c, so its declaration should not be in
16416 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16417 logically belongs with push_key_description.
16419 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16421 * buffer.h: Include <sys/types.h> instead of <time.h>.
16422 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16423 Problem reported by Herbert J. Skuhra.
16425 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16427 * xml.c (parse_region): Make the parsing work for
16428 non-comment-starting XML files again (bug#9144).
16430 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16432 * image.c (gif_load): Fix calculation of bottom and right corner.
16435 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16437 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16438 redisplay in small windows.
16440 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16442 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16444 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16446 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16447 Operate on live windows only.
16449 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16451 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16453 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16455 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16456 only under bidi iteration.
16458 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16460 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16462 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16464 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16465 Without this fix, the command to link temacs failed due to an
16466 undefined symbol __builtin_isnan. This is because
16467 /usr/include/iso/math_c99.h #defines isnan(x) to
16468 __builtin_isnan(x), but the bundled gcc, which identifies itself
16469 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16471 * floatfns.c (isnan): #undef, and then #define to a clone of
16473 (Fisnan): Always define, since it's always available now.
16474 (syms_of_floatfns): Always define isnan at the Lisp level.
16476 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16478 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16480 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16482 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16483 The previous code assumed that file offsets (off_t values) fit in
16484 EMACS_INT variables, which is not true on typical 32-bit hosts.
16485 The code messed up by falsely reporting buffer overflow in cases
16486 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16487 when "big" contains more than 2**29 bytes, even though this
16488 inserts just one byte and does not overflow the buffer.
16489 (Finsert_file_contents): Store file offsets as off_t
16490 values, not as EMACS_INT values. Check for overflow when
16491 converting between EMACS_INT and off_t. When checking for
16492 buffer overflow or for overlap, take the offsets into account.
16493 Don't use EMACS_INT for small values where int suffices.
16494 When checking for overlap, fix a typo: ZV was used where
16495 ZV_BYTE was intended.
16496 (Fwrite_region): Don't assume off_t fits into 'long'.
16497 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16499 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16501 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16503 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16505 sprintf-related integer and memory overflow issues (Bug#9412).
16507 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16508 (esprintf, exprintf, evxprintf): New functions.
16509 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16510 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16511 (modify_event_symbol): Do not assume that the length of
16512 name_alist_or_stem is safe to alloca and fits in int.
16513 (Fexecute_extended_command): Likewise for function name and binding.
16514 (Frecursion_depth): Wrap around reliably on integer overflow.
16515 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16516 since some callers pass EMACS_INT values.
16517 (Fsingle_key_description): Don't crash if symbol name contains more
16518 than MAX_ALLOCA bytes.
16519 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16520 (get_minibuffer): Arg is now EMACS_INT, not int.
16521 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16522 (esprintf, exprintf, evxprintf): New decls.
16523 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16525 * dbusbind.c (signature_cat): New function.
16526 (xd_signature, Fdbus_register_signal):
16527 Do not overrun buffer; instead, report string overflow.
16529 * dispnew.c (add_window_display_history): Don't overrun buffer.
16530 Truncate instead; this is OK since it's just a log.
16532 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16533 even if the time zone offset is outlandishly large.
16534 Don't mishandle offset == INT_MIN.
16536 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16537 when creating daemon; the previous buffer-overflow check was incorrect.
16539 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16540 which has the guts of the old verror function.
16542 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16543 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16545 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16546 (font_unparse_xlfd): Don't blindly alloca long strings.
16547 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16548 fits in int, when using sprintf. Use single snprintf to count
16549 length of string rather than counting it via multiple sprintfs;
16550 that's simpler and more reliable.
16551 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16552 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16553 sprintf, in case result does not fit in int.
16555 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16556 (fontset_from_font): Print it.
16558 * frame.c (tty_frame_count): Now printmax_t, not int.
16559 (make_terminal_frame, set_term_frame_name): Print it.
16560 (x_report_frame_params): In X, window IDs are unsigned long,
16561 not signed long, so print them as unsigned.
16562 (validate_x_resource_name): Check for implausibly long names,
16563 and don't assume name length fits in 'int'.
16564 (x_get_resource_string): Don't blindly alloca invocation name;
16565 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16568 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16569 (xg_check_special_colors, xg_set_geometry):
16570 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16572 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16573 Use esprintf, not sprintf, in case result does not fit in int.
16575 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16576 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16577 it as a large positive number.
16578 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16579 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16581 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16582 in case result does not fit in int.
16584 * print.c (float_to_string): Detect width overflow more reliably.
16585 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16586 buffer overrun. Don't assume list length fits in 'int'. Treat
16587 print length of 0 as 0, not as infinity; to be consistent with other
16588 uses of print length in this function. Don't overflow print length
16589 index. Don't assume hash table size fits in 'long', or that
16590 vectorlike size fits in 'unsigned long'.
16592 * process.c (make_process): Use printmax_t, not int, to format
16593 process-name gensyms.
16595 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16597 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16598 to avoid potential buffer overrun.
16600 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16601 if X resource line is longer than 512 bytes.
16603 * xfns.c (x_window): Make sprintf buffer a bit bigger
16604 to avoid potential buffer overrun.
16606 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16608 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16610 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16612 Integer overflow fixes for scrolling, etc.
16613 Without these, Emacs silently mishandles large integers sometimes.
16614 For example, "C-u 4294967297 M-x recenter" was treated as if
16615 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16617 * xdisp.c (try_window_id): Check Emacs fixnum range before
16618 converting to 'int'.
16620 * window.c (window_scroll_line_based, Frecenter):
16621 Check that an Emacs fixnum is in range before assigning it to 'int'.
16622 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16623 values converted from Emacs fixnums.
16624 (Frecenter): Don't wrap around a line count if it is out of 'int'
16625 range; instead, treat it as an extreme value.
16626 (Fset_window_configuration, compare_window_configurations):
16627 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16629 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16630 that can exceed INT_MAX. Check that EMACS_INT value is in range
16631 before assigning it to the (possibly-narrower) index.
16632 (match_limit): Don't assume that a fixnum can fit in 'int'.
16634 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16637 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16638 (Fvertical_motion): Don't wrap around LINES values that don't fit
16639 in 'int'. Instead, treat them as extreme values. This is good
16640 enough for windows, which can't have more than INT_MAX lines anyway.
16642 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16644 * Require libxml/parser.h to avoid compilation warning.
16646 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16648 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16649 since this reportedly can destroy thread storage.
16651 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16653 * syntax.c (find_defun_start): Update all cache variables if
16654 exiting early (Bug#9401).
16656 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16658 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16660 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16661 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16662 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16664 * term.c (tty_append_glyph): New function.
16665 (produce_stretch_glyph): Static function and its prototype deleted.
16667 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16670 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16672 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16673 when checking :margin (Bug#9390).
16674 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16675 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16676 so that the name doesn't mislead. All uses changed.
16678 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16680 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16683 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16685 * xdisp.c (move_it_to): Don't bail out early when reaching
16686 position beyond to_charpos, if we are scanning backwards.
16687 (move_it_vertically_backward): When DY == 0, make sure we get to
16688 the first character in the line after the newline.
16690 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16692 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16693 (ccl_driver): Do not generate an out-of-range pointer.
16694 (Fccl_execute_on_string): Remove unnecessary check for
16695 integer overflow, noted by Stefan Monnier in
16696 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16697 Remove a FIXME that didn't need fixing.
16698 Simplify the newly-introduced buffer reallocation code.
16700 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16702 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16704 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16706 Integer and memory overflow issues (Bug#9196).
16708 * doc.c (get_doc_string): Rework so that
16709 get_doc_string_buffer_size is the actual buffer size, rather than
16710 being 1 less than the actual buffer size; this makes xpalloc more
16713 * image.c (x_allocate_bitmap_record, cache_image):
16714 * xselect.c (Fx_register_dnd_atom):
16715 Simplify previous changes by using xpalloc.
16717 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16718 since either will do and ptrdiff_t is convenient with xpalloc.
16720 * charset.c (charset_table_size)
16721 (struct charset_sort_data.priority): Now ptrdiff_t.
16722 (charset_compare): Don't overflow if priorities differ greatly.
16723 (Fsort_charsets): Don't assume list length fits in int.
16724 Check for size-calculation overflow when allocating sort data.
16725 (syms_of_charset): Allocate an initial charset table that is
16726 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16728 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16730 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16731 The actual value is always <= INT_MAX, and leaving it unsigned made
16732 overflow checking harder.
16734 * dispextern.h (struct glyph_matrix.rows_allocated)
16735 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16736 with xpalloc. The values are still always <= INT_MAX.
16738 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16740 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16741 (SAFE_NALLOCA): New macro.
16743 * region-cache.c (struct boundary.pos, find_cache_boundary)
16744 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16745 (set_cache_region, invalidate_region_cache)
16746 (revalidate_region_cache, know_region_cache, region_cache_forward)
16747 (region_cache_backward, pp_cache):
16748 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16749 so that ptrdiff_t * can be passed to xpalloc.
16750 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16751 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16752 (pp_cache): Don't assume cache_len fits in int.
16753 * region-cache.h: Adjust extern decls to match.
16755 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16756 EMACS_INT, since either will do, for xpalloc.
16758 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16759 (xnmalloc, xnrealloc, xpalloc): New functions.
16761 * bidi.c (bidi_shelve_header_size): New constant.
16762 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16763 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16765 * bidi.c (bidi_cache_shrink):
16766 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16768 Don't update size of array until after memory allocation succeeds,
16769 because xmalloc/xrealloc may not return.
16770 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16771 now that we have proper integer overflow checking.
16772 (record_overlay_string, overlay_strings): Catch overflows when
16773 calculating size of overlay_str_buf.
16775 * callproc.c (Fcall_process): Check for size overflow when
16776 calculating size of args2.
16777 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16778 Normally we prefer signed values, but sticking with ptrdiff_t would
16779 require adding more-complicated checks.
16781 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16782 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16783 Redo buffer-overflow calculations to avoid integer overflow.
16784 Add a FIXME comment where memory seems to be over-allocated.
16786 * character.c (Fstring): Check for size-calculation overflow.
16788 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16789 unnecessary integer overflow. Check for size overflow.
16790 (encode_coding_object): Don't update size until xmalloc succeeds.
16792 * composite.c (get_composition_id): Check for overflow in glyph
16793 length calculations.
16795 Integer and memory overflow fixes for display code.
16796 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16797 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16798 (scrolling_window): Check for overflow in size calculations.
16799 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16800 Don't assume glyph table len fits in int.
16801 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
16802 (row_table_size): Now ptrdiff_t, not int.
16803 (scrolling_window): Avoid overflow in size calculations.
16804 Don't update size until allocation succeeds.
16805 * fns.c (concat): Check for overflow in size calculations.
16806 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16807 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16808 (NEXT_ALMOST_PRIME_LIMIT): New constant.
16810 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16811 (get_doc_string): Check for size calculation overflow.
16812 Don't update size until allocation succeeds.
16813 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16814 EMACS_INT, where ptrdiff_t will do.
16815 (Fsubstitute_command_keys): Check for string overflow.
16817 * editfns.c (set_time_zone_rule): Don't assume environment length
16819 (message_length): Now ptrdiff_t, not int.
16820 (Fmessage_box): Don't update size until allocation succeeds.
16821 Don't assume message length fits in int.
16822 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16824 * emacs.c (main): Do not reallocate argv, since there is a null at
16825 the end that can be overwritten, and this way there's no need to
16826 worry about size-calculation overflow.
16827 (sort_args): Check for size-calculation overflow.
16829 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16831 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16833 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16834 (x_set_scroll_bar_width, x_figure_window_size):
16835 Check for integer overflow.
16836 (x_set_alpha): Do not assume XINT fits in int.
16838 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16839 This is for the members text_lines, text_cols, total_lines, total_cols,
16840 where the system imposes an 'int' limit.
16842 * fringe.c (Fdefine_fringe_bitmap):
16843 Don't update size until alloc works.
16845 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16846 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16848 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16849 Check for size-calculation overflow.
16850 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16851 do, as we prefer signed integers.
16852 (id_to_widget.max_size, id_to_widget.used)
16853 (xg_store_widget_in_map, xg_remove_widget_from_map)
16854 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16855 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16856 Use and return ptrdiff_t, not int.
16857 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16858 * gtkutil.h: Change prototypes to match the above.
16860 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16861 are duplicate now that they've been promoted to lisp.h.
16862 (x_allocate_bitmap_record, x_alloc_image_color)
16863 (make_image_cache, cache_image, xpm_load):
16864 Don't update size until alloc is done.
16865 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
16867 Check for size calculation overflow.
16868 (ct_colors_allocated_max): New constant.
16869 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
16872 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
16873 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
16874 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16875 Use ptrdiff_t, not int, to count maps.
16876 (read_char_minibuf_menu_prompt): Check for overflow in size
16877 calculations. Don't update size until allocation succeeds.
16878 Redo calculations to avoid overflow.
16879 * keyboard.h: Change prototypes to match the above.
16881 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16883 (current_minor_maps): Check for size calculation overflow.
16884 * keymap.h: Change prototypes to match the above.
16886 * lread.c (read1, init_obarray): Don't update size until alloc done.
16888 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

16905 (Fset_match_data): Don't assume list lengths fit in 'int'.
16907 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16908 for command line length. Do not attempt to address one before the
16909 beginning of an array, as that's not portable.
16911 * term.c (max_frame_lines): Remove; unused.

16939 Check for size calculation overflow.
16940 (cache_face): Treat size calculation overflows as if they were
16941 memory exhaustion (the usual treatment), rather than aborting.
16943 * xfns.c (x_encode_text, x_set_name_internal)
16944 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16945 sizes, since they can exceed INT_MAX in size. Check for size
16946 calculation overflow.
16948 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16949 (xg_select): Check for size calculation overflow.
16950 Don't update size until alloc done.
16952 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16953 as sprintf is limited to int lengths.
16955 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16956 (X_LONG_MIN): New macros.
16957 Use them to make the following changes clearer.
16958 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16959 This change doesn't affect the value now, but it may help remind
16960 future maintainers not to raise the value too much later.
16961 (SELECTION_QUANTUM): Remove, replacing with ...
16962 (selection_quantum): ... new function, which avoids overflow.
16964 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16965 assumption that selection length fits in 'int'.
16966 (x_reply_selection_request, x_handle_selection_request)
16967 (x_get_window_property, receive_incremental_selection)

16982 Don't store size until memory allocation succeeds.
16983 (x_get_window_property): Plug memory leak on memory exhaustion.
16984 Don't double-block input; malloc is safe here. Don't assume 2**34
16985 - 4 fits in unsigned long. Add an xassert to check
16986 XGetWindowProperty overflow. Be more careful about overflow
16987 calculations, and distinguish size from memory overflow better.
16988 (receive_incremental_selection): When tracing, don't assume
16989 unsigned int is less than INT_MAX.
16990 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16991 harmful) conversions of unsigned short to int.

16993 in the range -65535 through -1 fit in an X unsigned short.
16994 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16995 result parameters unless successful. Rely on cons_to_unsigned
16996 to report problems with elements; the old code wasn't right anyway.
16997 (x_check_property_data): Check for int overflow; we cannot use
16998 a wider type due to X limits.
16999 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

17031 * lisp.h (hash_lookup, hash_put):
17032 * minibuf.c (Ftest_completion):
17033 Use ptrdiff_t for hash table indexes, not int (which is too
17034 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17035 32-bit --with-wide-int hosts).
17037 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17038 Add a FIXME comment about memory leaks.

17046 with outlandish widths.
17047 * character.h (sanitize_tab_width): Rename from sanitize_width,
17048 now that we have two such functions. All uses changed.

17066 * xterm.c: Don't go over XClientMessageEvent limit.
17067 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17068 (x_send_scroll_bar_event): Likewise. Check that the size does not
17069 exceed limits imposed by XClientMessageEvent, as well as the usual
17070 ptrdiff_t and size_t limits.
17072 * keyboard.c: Overflow, signedness and related fixes.
17073 (make_lispy_movement): Use same integer type in forward decl
17074 that is used in the definition.
17075 (read_key_sequence, keyremap_step):
17076 Change bufsize argument back to int, undoing my 2011-03-30 change.
17077 We prefer signed types, and int is wide enough here.
17078 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17079 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17080 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17081 length, not size_t. Use ptrdiff_t for index, not int.
17082 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17083 possibility of integer overflow.
17085 Overflow, signedness and related fixes for images.

17107 (lookup_image): Remove unnecessary tests.
17108 (xbm_image_p): Locals are now of int, not EMACS_INT,
17109 since parse_image_check makes sure they fit into int.
17110 (png_load, gif_load, svg_load_image):
17111 Prefer int to unsigned where either will do.
17112 (tiff_handler): New function, combining the cores of the
17113 old tiff_error_handler and tiff_warning_handler.
17114 This function is rewritten to use vsnprintf and thereby avoid
17115 stack buffer overflows. It uses only the features of vsnprintf
17116 that are common to both POSIX and native Microsoft.
17117 (tiff_error_handler, tiff_warning_handler): Use it.
17118 (tiff_load, gif_load, imagemagick_load_image):
17119 Don't assume :index value fits in 'int'.
17120 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17121 (imagemagick_load_image): Check that crop parameters fit into
17122 the integer types that MagickCropImage accepts. Don't assume
17123 Vimagemagick_render_type has a nonnegative value. Don't assume
17124 size_t fits in 'long'.
17125 (gs_load): Use printmax_t to print the widest integers possible.

17138 handle_single_display_spec, not just 1 or zero.
17139 (handle_single_display_spec): If the display spec is of the form
17140 `(space ...)', and specifies display in the text area, return 2
17142 (try_cursor_movement): Check for the need to scroll more
17143 accurately, and prefer exact match for point under bidi.
17144 Don't advance `row' beyond the last row of the window.

17162 buffers, return left-to-right.
17163 (set_cursor_from_row): Consider candidate row a win if its glyph
17164 represents a newline and point is on that newline. Fixes cursor
17165 positioning on the newline at EOL of R2L text within L2R
17166 paragraph, and vice versa.
17167 (try_cursor_movement): Check continued rows, in addition to
17168 continuation rows. Fixes unwarranted scroll when point enters a
17169 continued line of R2L text within an L2R paragraph, or vice versa.
17170 (cursor_row_p): Consider the case of point being equal to
17171 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17172 from the end of a short line to the beginning of a continued line
17173 of R2L text within L2R paragraph.

17200 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17201 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17202 candidate is selected by the mouse, and that candidate has a
17203 composed character under the mouse.
17205 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17206 coordinates reported by pos-visible-in-window-p for a composed
17207 character in column zero.
17209 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

17215 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17216 consider it a hit if to_charpos is anywhere in the range of the
17217 composed buffer positions.
17219 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17221 * image.c (gif_load): Don't assume that each subimage has the same
17222 dimensions as the base image. Handle disposal method that is
17223 "undefined" by the gif spec (Bug#9335).
17225 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17227 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17237 a composition, take its buffer position from IT->cmp_it.charpos.
17238 Fixes cursor positioning at the beginning of a line that begins
17239 with a composed character.
17241 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17243 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17244 character bidirectional type, use STRONG_L instead. Fixes crashes
17245 in a buffer produced by `describe-categories'.
17247 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17248 members before the level stack, so they would be saved and
17249 restored when copying iterator state. Fixes incorrect reordering
17250 around TABs covered by display properties.

17325 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17326 ppos_it. Fixes vertical cursor motion when line beginning is
17327 covered by an image. (Bug#9296)
17329 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17331 * nsterm.h (ns_run_ascript): Declare.
17332 (NSAPP_DATA2_RUNASSCRIPT): Define.
17334 * nsfns.m (as_script, as_result, as_status): New static variables.
17335 (ns_run_ascript): New function.
17336 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17337 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17338 the event loop. Get status from as_status (Bug#7276).
17340 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17341 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17342 the event loop (Bug#7276).
17344 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17346 * gnutls.c (QCgnutls_bootprop_priority)
17347 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
17348 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
17349 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
17350 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
17351 (QCgnutls_bootprop_verify_hostname_error)
17352 (QCgnutls_bootprop_callbacks_verify): Rename from
17353 Qgnutls_bootprop_..., all uses changed.
17355 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
17358 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
17360 * xfaces.c (Qframe_set_background_mode): Now static.
17361 * dispextern.h (Qframe_set_background_mode): Remove decl.
17363 * process.c (Fnetwork_interface_info): Declare local only if needed.
17365 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
17367 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
17368 (Fnetwork_interface_list): Allocate in increments of bytes instead
17369 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17370 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17372 (struct ifflag_def): notrailers is smart on OSX.
17373 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17374 Get hardware address with getifaddrs if available.
17376 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17378 * xdisp.c (iterate_out_of_display_property): xassert that
17379 IT->position is set to within IT->object's boundaries. Break from
17380 the loop as soon as EOB is reached; avoids infloops in redisplay
17381 when IT->position is set up wrongly due to some bug.
17382 Set IT->current to match the bidi iterator unconditionally.
17383 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17384 entry. Force push_it to save on the stack the current
17385 buffer/string position, to be restored by pop_it. Fix flags in
17386 the iterator structure wrt the object coming from a display
17387 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17388 properties. (Bug#9284)
17390 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17392 * fontset.c (fontset_get_font_group): Add proper type checks.
17395 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17397 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
17398 and LC_VERSION_MIN_MACOSX.
17399 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
17400 (dump_it) [LC_FUNCTION_STARTS]: Use it.
17402 2011-08-08 Eli Zaretskii <eliz@gnu.org>
17404 * xdisp.c (forward_to_next_line_start): Allow to use the
17405 no-display-properties-and-no-overlays under bidi display.
17406 Set disp_pos in the bidi iterator to avoid searches for display
17407 properties and overlays.
17409 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17411 * editfns.c (Fset_time_zone_rule): Document relationship with the
17414 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
17415 the font entity extracted from the cache (Bug#8109).
17417 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17419 * composite.c (autocmp_chars): Don't reset point. That is done by
17420 restore_point_unwind (Bug#5984).
17422 2011-08-07 Juri Linkov <juri@jurta.org>
17424 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17425 to show the arg `TIME' instead of `TIMEVAL'.
17427 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17429 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17430 display property strides EOL and includes a newline, as in
17431 longlines-mode. (Bug#9254)
17432 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17433 word-wrap under bidirectional display. (Bug#9224)
17435 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17436 is non-zero, even if the data buffer is NULL. Fixes a crash in
17437 vertical-motion with longlines-mode. (Bug#9254)
17439 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17441 * bidi.c <bidi_cache_total_alloc>: Now static.
17442 (bidi_initialize): Initialize bidi_cache_total_alloc.
17444 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17447 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17448 amount allocated this far in `bidi_cache_total_alloc'.
17449 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17450 non-zero, only free the data buffer without restoring the cache
17451 contents. All callers changed.
17453 * dispextern.h (bidi_unshelve_cache): Update prototype.
17455 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17456 (move_it_in_display_line, move_it_to)
17457 (move_it_vertically_backward, move_it_by_lines): Replace the call
17458 to xfree to an equivalent call to bidi_unshelve_cache.
17459 (move_it_in_display_line_to): Fix logic of returning
17460 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17462 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17464 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17465 came from a string character with a `cursor' property. (Bug#9229)
17467 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17469 * Makefile.in (LIB_PTHREAD): New variable.
17470 (LIBES): Add LIB_PTHREAD (Bug#9216).
17472 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17473 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17475 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17477 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17479 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17481 * xterm.c (x_find_topmost_parent): New function.
17482 (x_set_frame_alpha): Find topmost parent window with
17483 x_find_topmost_parent and set the property there also (bug#9181).
17484 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17486 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17488 * callproc.c (Fcall_process): Avoid vfork clobbering
17489 the local vars buffer, coding_systems, current_dir.
17491 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17493 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17495 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17497 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17498 so that it is not optimized away.
17500 * xdisp.c (compute_display_string_pos): Remove unused local.
17502 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17504 Fix slow cursor motion and scrolling in large buffers with
17505 selective display, like Org Mode buffers. (Bug#9218)
17507 * dispextern.h (struct bidi_it): New member disp_prop_p.
17509 * xdisp.c: Remove one-slot cache of display string positions.
17510 (compute_display_string_pos): Accept an additional argument
17511 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17512 for a display string or property. If found, set DISP_PROP_P
17515 * bidi.c (bidi_fetch_char): Accept an additional argument
17516 DISP_PROP_P, and pass it to compute_display_string_pos.
17517 Only handle text covered by a display string if DISP_PROP_P is returned
17518 non-zero. All callers of bidi_fetch_char changed.
17520 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17522 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17524 2010-12-03 Don March <don@ohspite.net>
17526 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17527 last character M-[char] is translated to ESC [char] (bug#7541).
17529 2011-08-02 Kenichi Handa <handa@m17n.org>
17531 * lisp.h (uniprop_table): Extern it.
17533 * chartab.c (uniprop_table): Make it non-static.
17535 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17537 * xdisp.c (forward_to_next_line_start): Accept additional argument
17538 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17540 (reseat_at_next_visible_line_start): Use the bidi iterator state
17541 returned by forward_to_next_line_start to restore the state of
17542 it->bidi_it after backing up to previous newline. (Bug#9212)
17544 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17546 * regex.c (re_comp): Protoize.
17547 (re_exec): Fix return type.
17548 (regexec): Fix type of `ret'. (Bug#9203)
17550 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17552 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17553 This is needed if max-image-size is a floating-point number.
17555 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17557 * print.c (print_object): Print empty symbol as ##.
17559 * lread.c (read1): Read ## as empty symbol.
17561 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17563 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17564 setting frame foreground color (Bug#9175).
17565 (x_set_background_color): Likewise.
17567 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17568 contents (Bug#9176).
17569 (EmacsTooltip -init): Remove bezels and add shadows to
17572 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17573 or scroll bar (Bug#8470).
17575 * nsfont.m (nsfont_open): Remove assignment to voffset and
17576 unnecessary vars hshink, expand, hd, full_height, min_height.
17577 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17579 * nsterm.h (nsfont_info): Remove voffset field.
17581 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17583 Implement strike-through and overline on NextStep (Bug#8863).
17585 * nsfont.m (nsfont_open): Use underline position provided by font,
17586 instead of hard-coded value of 2.
17587 (nsfont_draw): Call ns_draw_text_decoration instead.
17589 * nsterm.h: Add declaration for ns_draw_text_decoration.
17591 * nsterm.m (ns_draw_text_decoration): New function for drawing
17592 underline, overline, and strike-through.
17593 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17594 ns_draw_text_decoration. Change treatment of cursor drawing to
17595 accommodate underlining, etc.
17597 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17599 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17602 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17604 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17605 Without this fix, if a signal arrives just after memory fills up,
17606 'malloc' might be invoked reentrantly.
17608 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17609 In other words, assume that every image size is allowed, on non-X
17610 hosts. This assumption is probably wrong, but it lets Emacs compile.
17612 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17614 * regex.c (re_iswctype): Convert return values to boolean.
17616 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17618 * xdisp.c (compute_display_string_pos): Don't use cached display
17619 string position if the buffer had its restriction changed.
17622 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17624 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17626 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17628 Integer signedness and overflow and related fixes. (Bug#9079)
17630 * bidi.c: Integer size and overflow fixes.
17631 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17632 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17633 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17634 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17635 (bidi_find_other_level_edge):
17636 Use ptrdiff_t instead of EMACS_INT where either will do.
17637 This works better on 32-bit hosts configured --with-wide-int.
17638 (bidi_cache_ensure_space): Check for size-calculation overflow.
17639 Use % rather than repeated addition, for better worst-case speed.
17640 Don't set bidi_cache_size until after xrealloc returns, because it
17642 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17643 (bidi_cache_ensure_space): Also check that the bidi cache size
17644 does not exceed that of the largest Lisp string or buffer. See Eli
17645 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17647 * alloc.c (__malloc_size_t): Remove.
17648 All uses replaced by size_t. See Andreas Schwab's note
17649 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17651 * image.c: Improve checking for integer overflow.
17652 (check_image_size): Assume that f is nonnull, since
17653 it is always nonnull in practice. This is one less thing to
17654 worry about when checking for integer overflow later.
17655 (x_check_image_size): New function, which checks for integer
17656 overflow issues inside X.
17657 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17658 This removes the need for a memory_full check.
17659 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17660 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17661 (xbm_read_bitmap_data): Change locals back to 'int', since
17662 their values must fit in 'int'.
17663 (xpm_load_image, png_load, tiff_load):
17664 Invoke x_create_x_image_and_pixmap earlier,
17665 to avoid much needless work if the image is too large.
17666 (tiff_load): Treat overly large images as if
17667 x_create_x_image_and_pixmap failed, not as malloc failures.
17668 (gs_load): Use x_check_image_size.
17670 * gtkutil.c: Omit integer casts.
17671 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17672 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17674 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17676 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17677 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17678 would wrongly return t on a 64-bit host.
17680 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17681 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17682 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17683 and therefore cause GCC to emit a bogus diagnostic in some cases.
17685 * image.c: Integer signedness and overflow and related fixes.
17686 This is not an exhaustive set of fixes, but it's time to
17687 record what I've got.
17688 (lookup_pixel_color, check_image_size): Remove redundant decls.
17689 (check_image_size): Don't assume that arbitrary EMACS_INT values
17690 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17691 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17692 (tiff_load, imagemagick_load_image):
17693 Check for overflow in size calculations.
17694 (x_create_x_image_and_pixmap): Remove unnecessary test for
17695 xmalloc returning NULL; that can't happen.
17696 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17697 (xpm_color_bucket): Use better integer hashing function.
17698 (xpm_cache_color): Don't possibly over-allocate memory.
17699 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17700 (gif_memory_source):
17701 Use ptrdiff_t, not int or size_t, to record sizes.
17702 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17703 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17704 either works, as we prefer signed integers.
17705 (tiff_read_from_memory, tiff_write_from_memory):
17706 Return tsize_t, not size_t, since that's what the TIFF API wants.
17707 (tiff_read_from_memory): Don't fail simply because the read would
17708 go past EOF; instead, return a short read.
17709 (tiff_load): Omit no-longer-needed casts.
17710 (Fimagemagick_types): Don't assume size fits into 'int'.
17712 Improve hashing quality when configured --with-wide-int.
17713 * fns.c (hash_string): New function, taken from sxhash_string.
17714 Do not discard information about ASCII character case; this
17715 discarding is no longer needed.
17716 (sxhash-string): Use it. Change sig to match it. Caller changed.
17717 * lisp.h: Declare it.
17718 * lread.c (hash_string): Remove, since we now use fns.c's version.
17719 The fns.c version returns a wider integer if --with-wide-int is
17720 specified, so this should help the quality of the hashing a bit.
17722 * emacs.c: Integer overflow minor fix.
17723 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17724 Define only if GNU_LINUX.
17725 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17727 * dispnew.c: Integer signedness and overflow fixes.
17728 Remove unnecessary forward decls, that were a maintenance hassle.
17729 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17731 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17732 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17733 (prepare_desired_row, line_draw_cost):
17734 Use int, not unsigned, where either works.
17735 (save_current_matrix, restore_current_matrix):
17736 Use ptrdiff_t, not size_t, where either works.
17737 (init_display): Check for overflow more accurately, and without
17738 relying on undefined behavior.
17740 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17741 Remove, replacing with the new symbols in lisp.h. All uses changed.
17742 * fileio.c (make_temp_name):
17743 * filelock.c (lock_file_1, lock_file):
17744 * xdisp.c (message_dolog):
17745 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17746 Use pMd etc. instead.
17747 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17748 replacing the pWIDE etc. symbols removed from editfns.c.
17750 * keyboard.h (num_input_events): Now uintmax_t.
17751 This is (very slightly) less likely to mess up due to wraparound.
17754 * buffer.c: Integer signedness fixes.
17755 (alloc_buffer_text, enlarge_buffer_text):
17756 Use ptrdiff_t rather than size_t when either will do, as we prefer
17759 * alloc.c: Integer signedness and overflow fixes.
17760 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17761 (__malloc_size_t): Default to size_t, not to int.
17762 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17763 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17764 Prefer ptrdiff_t to size_t when either would do, as we prefer
17766 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17767 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17768 Now const. Initialize with values that are in range even if char
17770 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17771 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17772 These functions do the right thing with sizes > 2**32.
17773 (check_depth): Now ptrdiff_t, not int.
17774 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17775 Adjust to new way of storing sizes. Check for size overflow bugs
17777 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17778 slightly wrong anyway, as it missed one instance of
17779 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17780 (refill_memory_reserve): Omit needless cast to size_t.
17781 (mark_object_loop_halt): Mark as externally visible.
17783 * xselect.c: Integer signedness and overflow fixes.
17784 (Fx_register_dnd_atom, x_handle_dnd_message):
17785 Use ptrdiff_t, not size_t, since we prefer signed.
17786 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17787 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17788 x_dnd_atoms_size and x_dnd_atoms_length.
17790 * doprnt.c: Prefer signed to unsigned when either works.
17792 * doprnt.c (doprnt):
17794 * xdisp.c (vmessage):
17795 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17796 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17797 prefer signed arithmetic to avoid comparison confusion.
17798 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17799 but is a bit tricky.
17801 Assume freestanding C89 headers, string.h, stdlib.h.
17802 * data.c, doprnt.c, floatfns.c, print.c:
17803 Include float.h unconditionally.
17804 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17805 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17806 * regex.c: Likewise for stddef.h, string.h.
17807 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17808 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17809 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17810 (STDC_HEADERS): Remove obsolete defines.
17811 * sysdep.c: Include limits.h unconditionally.
17813 Assume support for memcmp, memcpy, memmove, memset.
17814 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17815 * regex.c (memcmp, memcpy):
17816 Remove; we assume C89 now.
17818 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17819 (__malloc_safe_bcopy): Remove; no longer needed.
17821 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17822 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17823 well either way, and we prefer signed to unsigned.
17825 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17827 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17828 closes the connection while we're reading (bug#9182).
17830 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17832 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17833 are specified (Bug#9168).
17835 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17837 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17838 Found by GCC static checking and --with-wide-int on a 32-bit host.
17840 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17842 * xdisp.c (compute_display_string_pos): Fix logic of caching
17843 previous display string position. Initialize cached_prev_pos to
17844 -1. Fixes slow-down at the beginning of a buffer.
17846 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17848 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17849 for attrs[LFACE_FONTSET_INDEX].
17851 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17853 * xml.c (parse_region): Remove unused local
17854 that was recently introduced.
17856 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17858 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17859 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17861 * xdisp.c (move_it_in_display_line_to): Record the best matching
17862 position for TO_CHARPOS while scanning the line, and restore it on
17863 exit if none of the characters scanned was an exact match.
17864 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17865 when exact match is impossible due to invisible text, and the
17866 lines are truncated.
17868 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17870 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17873 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17875 Fix a significant slow-down of cursor motion with C-n, C-p,
17876 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17877 auto-repeat under bidi redisplay in fontified buffers.
17878 * xdisp.c (compute_stop_pos_backwards): New function.
17879 (next_element_from_buffer): Call compute_stop_pos_backwards to
17880 find a suitable prev_stop when we find ourselves before
17882 (reseat): Don't look for prev_stop, as that could mean a very long
17884 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17885 <cached_disp_overlay_modiff>: Cache for last found display string
17887 (compute_display_string_pos): Return the cached position if asked
17888 about the same buffer in the same area of character positions, and
17889 the buffer wasn't changed since the time the display string
17890 position was cached.
17892 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17894 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17895 is an integer, which is important for empty lines. (Bug#9149)
17897 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17899 * frame.c (Fmodify_frame_parameters): In tty case, update the
17900 default face if necessary (Bug#4238).
17902 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17904 * editfns.c (Fstring_to_char): No need to explain what a character
17905 is in the docstring (Bug#6576).
17907 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17909 * xml.c (parse_region): Make sure we always return a tree.
17911 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17913 * xml.c (parse_region): If a document contains only comments,
17916 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17918 * xml.c (make_dom): Return comments, too.
17920 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17923 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17924 and the surrounding thread.
17925 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17926 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17927 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17929 * s/openbsd.h (BROKEN_SIGIO): Define.
17930 * unexelf.c (unexec) [__OpenBSD__]:
17931 Don't update the .mdebug section of the Alpha COFF symbol table.
17933 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17935 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17938 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17940 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17941 This fixes some race conditions on the permissions of any newly
17944 * alloc.c (valid_pointer_p): Use pipe, not open.
17945 This fixes some permissions issues when debugging.
17947 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17948 If fchown fails to set both uid and gid, try to set just gid,
17949 as that is sometimes allowed. Adjust the file's mode to eliminate
17950 setuid or setgid bits that are inappropriate if fchown fails.
17952 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17954 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17955 to compare Lisp_Objects.
17956 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17957 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17958 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17960 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17962 * lread.c (read_integer): Unread even EOF character.
17963 (read1): Likewise. Properly record start position of symbol.
17965 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17966 symbol character follows.
17968 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17970 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17971 This works around a problem with the previous change to Fcopy_file.
17972 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17973 and without this change, GCC might complain about discarding
17974 fchown's return value.
17976 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17978 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17980 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17982 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17984 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17986 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17987 it's used from the C level.
17989 * process.c: Use the same condition for POLL_FOR_INPUT in both
17990 keyboard.c and process.c (bug#1858).
17992 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17994 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17995 (Fgnutls_boot): Use it.
17997 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17999 * doc.c (Fsubstitute_command_keys): Revert last change.
18001 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18003 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18004 quotes the next character, and doesn't affect other longer
18005 sequences (bug#8935).
18007 * lread.c (syms_of_lread): Clarify that is isn't only
18008 `eval-buffer' and `eval-defun' that's affected by
18009 `lexical-binding' (bug#8460).
18011 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18013 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18014 bidi redisplay when a line includes both an image and is truncated.
18016 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18018 Fix minor problems found by static checking.
18019 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18020 (elsz): Now a signed constant, not a size_t var. We prefer signed
18021 types to unsigned, to avoid integer comparison confusion. Without
18022 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18023 "cannot optimize loop, the loop counter may overflow", a symptom
18025 * indent.c (Fvertical_motion): Mark locals as initialized.
18026 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18028 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18030 * search.c (Fre_search_backward): Mention `case-fold-search' in
18031 all the re_search_* functions (bug#8138).
18033 * keyboard.c (Fopen_dribble_file): Document when the file is

18046 bidi_it->string.schars.
18047 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
18048 NULL (avoids a crash in bidi_paragraph_init).
18049 Initialize itb.string.lstring.
18050 (init_iterator): Call bidi_init_it only of a valid
18051 buffer position was specified. Initialize paragraph_embedding to
18053 (reseat_to_string): Initialize the bidi iterator.
18054 (display_string): If we need to ignore text properties of
18055 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18056 original value of -1 will not work with bidi.)
18057 (compute_display_string_pos): First arg is now struct
18058 `text_pos *'; all callers changed. Support display properties on
18060 (compute_display_string_end): Support display properties on Lisp
18062 (init_iterator, reseat_1, reseat_to_string): Initialize the
18063 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18064 when iterating on a string not from display properties).
18065 (compute_display_string_pos, compute_display_string_end):
18066 Fix calculation of the object to scan. Fixes an error when using
18068 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18069 base_level_stop; instead, set base_level_stop to BEGV.
18070 Fixes crashes in vertical-motion.
18071 (next_element_from_buffer): Improve commentary for when
18072 the iterator is before prev_stop.
18073 (init_iterator): Initialize bidi_p from the default value of
18074 bidi-display-reordering, not from buffer-local value. Use the
18075 buffer-local value only if initializing for buffer iteration.
18076 (handle_invisible_prop): Support invisible properties on strings
18077 that are being bidi-reordered.
18078 (set_iterator_to_next): Support bidi reordering of C strings and
18080 (next_element_from_string): Support bidi reordering of Lisp
18082 (handle_stop_backwards): Support Lisp strings as well.
18083 (display_string): Support display of R2L glyph rows.
18084 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18085 (init_iterator): Don't initialize it->bidi_p for strings
18087 (reseat_to_string): Initialize it->bidi_p for strings here.
18088 (next_element_from_string, next_element_from_c_string)
18089 (next_element_from_buffer): Add xassert's for correspondence
18090 between IT's object being iterated and it->bidi_it.string

18093 (next_element_from_c_string): Handle the case of the first string
18094 character that is not the first one in the visual order.
18095 (get_visually_first_element): New function, refactored from common
18096 parts of next_element_from_buffer, next_element_from_string, and
18097 next_element_from_c_string.
18098 (tool_bar_lines_needed, redisplay_tool_bar)
18099 (display_menu_bar): Force left-to-right direction. Add a FIXME
18100 comment for making that be controlled by a user option.
18101 (push_it, pop_it): Save and restore the state of the
18102 bidi iterator. Save and restore the bidi_p flag.
18103 (pop_it): Iterate out of display property for string iteration as
18105 (iterate_out_of_display_property): Support iteration over strings.
18106 (handle_single_display_spec): Set up it->bidi_it for iteration
18107 over a display string, and call bidi_init_it.
18108 (handle_single_display_spec, next_overlay_string)
18109 (get_overlay_strings_1, push_display_prop): Set up the bidi
18110 iterator for displaying display or overlay strings.
18111 (forward_to_next_line_start): Don't use the shortcut if
18113 (back_to_previous_visible_line_start): If handle_display_prop
18114 pushed the iterator stack, restore the internal state of the bidi
18115 iterator by calling bidi_pop_it same number of times.
18116 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18117 and we are bidi-iterating, don't decrement the iterator position;
18118 instead, set the first_elt flag in the bidi iterator, to produce
18120 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18121 (push_display_prop): xassert that we are iterating a buffer.
18122 (push_it, pop_it): Save and restore paragraph_embedding member.
18123 (handle_single_display_spec, next_overlay_string)
18124 (get_overlay_strings_1, reseat_1, reseat_to_string)
18125 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18126 correctly. Don't assume unibyte strings are not bidi-reordered.
18127 (compute_display_string_pos)
18128 (compute_display_string_end): Fix handling the case of C string.
18129 (push_it, pop_it): Save and restore from_disp_prop_p.

18134 popping after iteration over a string that came from a display
18135 property. Fix a typo in popping stretch info. Add an assertion
18136 for verifying that the iterator position is in sync with the bidi
18138 (handle_single_display_spec, get_overlay_strings_1)
18139 (push_display_prop): Fix initialization of paragraph direction for
18140 string when that of the parent object is not yet determined.
18141 (reseat_1): Call bidi_init_it to resync the bidi
18142 iterator with IT's position. (Bug#7616)
18143 (find_row_edges): If ROW->start.pos gives position
18144 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
18145 (handle_stop, back_to_previous_visible_line_start, reseat_1):
18146 Reset the from_disp_prop_p flag.
18147 (SAVE_IT, RESTORE_IT): New macros.
18148 (pos_visible_p, face_before_or_after_it_pos)
18149 (back_to_previous_visible_line_start)
18150 (move_it_in_display_line_to, move_it_in_display_line)
18151 (move_it_to, move_it_vertically_backward, move_it_by_lines)
18152 (try_scrolling, redisplay_window, display_line): Use them when
18153 saving a temporary copy of the iterator and restoring it back.
18154 (back_to_previous_visible_line_start, reseat_1)
18155 (init_iterator): Empty the bidi cache "stack".
18156 (move_it_in_display_line_to): If iterator ended up at
18157 EOL, but we never saw any buffer positions smaller than
18158 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
18159 motion in bidi-reordered lines.
18160 (move_it_in_display_line_to): Record prev_method and prev_pos
18161 immediately before the call to set_iterator_to_next. Fixes cursor
18162 motion in bidi-reordered lines with stretch glyphs and strings
18163 displayed in margins. (Bug#8133) (Bug#8867)
18164 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
18166 (pos_visible_p): Support positions in bidi-reordered lines.
18167 Save and restore bidi cache.
18169 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
18170 (bidi_paragraph_info): Delete unused struct.
18171 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
18172 (bidi_cache_start): New variable.
18173 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
18175 (bidi_cache_fetch_state, bidi_cache_search)
18176 (bidi_cache_find_level_change, bidi_cache_iterator_state)
18177 (bidi_cache_find, bidi_peek_at_next_level)

18181 (bidi_fetch_char): Accept new argument STRING; all callers
18182 changed. Support iteration over a string. Support strings with
18183 display properties. Support unibyte strings. Fix the type of
18184 `len' according to what STRING_CHAR_AND_LENGTH expects.
18185 (bidi_paragraph_init, bidi_resolve_explicit_1)
18186 (bidi_resolve_explicit, bidi_resolve_weak)
18187 (bidi_level_of_next_char, bidi_move_to_visually_next):
18188 Support iteration over a string.
18189 (bidi_set_sor_type, bidi_resolve_explicit_1)
18190 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
18191 can now be zero (for strings); special values 0 and -1 were
18192 changed to -1 and -2, respectively.
18193 (bidi_char_at_pos): New function.
18194 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
18195 Call it instead of FETCH_MULTIBYTE_CHAR.
18196 (bidi_move_to_visually_next): Abort if charpos or bytepos were not
18197 initialized to valid values.
18198 (bidi_init_it): Don't initialize charpos and bytepos with invalid

18280 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
18282 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
18283 The old code sometimes used this field without initializing it.
18285 * alloc.c (gc_sweep): Don't read past end of array.
18286 In theory, the old code could also have corrupted Emacs internals,
18287 though it'd be very unlikely.

18550 (clone_per_buffer_values): Don't assume that

18552 This isn't true in general, and it's particularly not true
18553 if Emacs is configured with --with-wide-int.
18554 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18555 New macros, used in the buffer.c change.

18591 Random fixes. E.g., (random) never returned negative values.
18592 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18593 subseconds part to the entropy, as that's a bit more random.
18594 Prefer signed to unsigned, since the signedness doesn't matter and
18595 in general we prefer signed. When given a limit, use a
18596 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18597 latter isn't right if USE_2_TAGS_FOR_INTS.
18598 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18599 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18611 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18612 This is more efficient than Ffile_directory_p and avoids a minor race.
18614 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18616 * buffer.c (Foverlay_put): Say what the return value is
18619 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18620 is a directory before asking whether to use the file name
18622 (barf_or_query_if_file_exists): Make the "File is a directory"
18623 error be more correct.
18625 * fns.c (Frequire): Remove the mention of the .gz files, since
18626 that's installation-specific, but keep the mention of

18631 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18639 Qgnutls_bootprop_verify_error (which is no longer used).
18641 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18642 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18643 Also (re)move comments that are misplaced or no longer relevant.
18645 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
18647 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

18744 * eval.c (struct backtrace): Simplify and port the data structure.
18745 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18746 signed bit field, as this assumption is not portable and it makes
18747 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18748 "char debug_on_exit : 1" as this is not portable either; instead,
18749 use the portable "unsigned int debug_on_exit : 1". Remove unused
18750 member evalargs. Remove obsolete comments about cc bombing out.

18940 (read1): Check for integer overflow in radices, and in
18941 read-circle numbers.

18985 on undefined behavior with wrong number of arguments.
18986 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18987 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18988 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18989 since we're not interested in debugging glyphs with old libraries.
18990 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18991 GCC 4.6.0's static checking.
18993 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

19032 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
19033 (x_session_initialize): Do not assume string length fits in int.
19035 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
19036 This is unlikely, but can occur if DPI is outlandish.
19038 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19039 * xselect.c (Fx_get_atom_name): Avoid need for strlen.

19054 (message_dolog): Don't assume print length fits in 39 bytes.
19055 (display_mode_element): Don't assume strlen fits in int.
19057 * termcap.c: Don't assume sizes fit in int and never overflow.

19061 * minibuf.c (Fread_buffer):
19062 * lread.c (intern, intern_c_string):
19063 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:

19081 Don't assume pid_t and time_t fit in unsigned long.
19082 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19083 (current_lock_owner): Prefer signed type for sizes.
19084 Use memcpy, not strncpy, where memcpy is what is really wanted.
19085 Don't assume (via atoi) that time_t and pid_t fit in int.
19086 Check for time_t and/or pid_t out of range, e.g., via a network share.
19087 Don't alloca where an auto var works fine.
19089 * fileio.c: Fix some integer overflow issues.
19090 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19091 Don't assume string length fits in int.
19092 (directory_file_name): Don't assume string length fits in long.
19093 (make_temp_name): Don't assume pid fits in int, or that its print
19094 length is less than 20.
19096 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19098 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19100 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19102 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19103 We prefer signed integers, even for size calculations.
19105 * emacs.c: Don't assume string length fits in 'int'.
19106 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19107 (main): Don't invoke strlen when not needed.
19109 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19110 (XD_DEBUG_MESSAGE): Don't waste a byte.
19112 * callproc.c (getenv_internal_1, getenv_internal)
19113 (Fgetenv_internal):
19114 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19116 * lread.c (invalid_syntax): Omit length argument.
19117 All uses changed. This doesn't fix a bug, but it simplifies the
19118 code away from its former Hollerith-constant appearance, and it's
19119 one less 'int' to worry about when looking at integer-overflow issues.
19120 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19122 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19123 This didn't break anything, but it didn't help either.
19124 It's confusing to put a bogus integer in a place where the actual
19125 value does not matter.
19126 (LIST_END_P): Remove unused macro and its bogus comment.
19127 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19129 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19130 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19132 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19133 We prefer signed types, and the value cannot exceed the EMACS_INT
19134 range anyway (because otherwise the length would not be representable).
19135 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19136 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19137 This avoids a GCC warning when WIDE_EMACS_INT.
19139 * indent.c (sane_tab_width): New function.
19140 (current_column, scan_for_column, Findent_to, position_indentation)
19141 (compute_motion): Use it. This is just for clarity.
19142 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19144 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19146 * lisp.h (lint_assume): New macro.
19147 * composite.c (composition_gstring_put_cache):
19148 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19150 * editfns.c, insdel.c:
19151 Omit unnecessary forward decls, to simplify future changes.
19153 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19155 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19157 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19158 Use much-faster test for byte-length change.
19159 Don't assume string byte-length fits in 'int'.
19160 Check that character arg fits in 'int'.
19161 (mapcar1): Declare byte as byte, for clarity.
19163 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19165 * fns.c (concat): Catch string overflow earlier.
19166 Do not rely on integer wraparound.
19168 * dispextern.h (struct it.overlay_strings_charpos)
19169 (struct it.selective): Now EMACS_INT, not int.
19170 * xdisp.c (forward_to_next_line_start)
19171 (back_to_previous_visible_line_start)
19172 (reseat_at_next_visible_line_start, next_element_from_buffer):
19173 Don't arbitrarily truncate the value of 'selective' to int.
19175 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19177 * composite.c: Don't truncate sizes to 'int'.
19178 (composition_gstring_p, composition_reseat_it)
19179 (composition_adjust_point): Use EMACS_INT, not int.
19180 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19181 not EMACS_UINT, for indexes.
19183 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19185 * buffer.c: Include <verify.h>.
19186 (struct sortvec.priority, struct sortstr.priority):
19187 Now EMACS_INT, not int.
19188 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19189 (struct sortstr.size, record_overlay_string)
19190 (struct sortstrlist.size, struct sortlist.used):
19191 Don't truncate size to int.
19192 (record_overlay_string): Check for size-calculation overflow.
19193 (init_buffer_once): Check at compile-time, not run-time.
19195 2011-06-22 Jim Meyering <meyering@redhat.com>
19197 Don't leak an XBM-image-sized buffer
19198 * image.c (xbm_load): Free the image buffer after using it.
19200 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19203 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19204 that Sun C diagnosed.
19205 * fns.c (secure_hash): Fix pointer signedness issue.
19206 * intervals.c (static_offset_intervals): New function.
19207 (offset_intervals): Use it.
19209 2011-06-21 Leo Liu <sdl.web@gmail.com>
19212 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19215 * fns.c (secure_hash): Rename from crypto_hash_function and change
19216 the first arg to accept symbols.
19217 (Fsecure_hash): New primitive.
19218 (syms_of_fns): New symbols.
19220 2011-06-20 Deniz Dogan <deniz@dogan.se>
19222 * process.c (Fset_process_buffer): Clarify return value in
19225 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19227 * dispnew.c (add_window_display_history): Use BVAR.
19229 * xdisp.c (debug_method_add): Use BVAR.
19230 (check_window_end, dump_glyph_matrix, dump_glyph)
19231 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19233 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19236 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19237 check till after the cache is created in init_frame_faces.
19239 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19241 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19243 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19245 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19246 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19247 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19249 Improve buffer-overflow checking (Bug#8873).
19250 * fileio.c (Finsert_file_contents):
19251 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19252 Remove the old (too-loose) buffer overflow checks.
19253 They weren't needed, since make_gap checks for buffer overflow.
19254 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19255 The old code merely checked for Emacs fixnum overflow, and relied
19256 on undefined (wraparound) behavior. The new code avoids undefined
19257 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19259 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19260 Tune. Don't use wider integers than needed. Don't use alloca.
19261 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19263 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19265 * insdel.c, lisp.h (buffer_overflow): New function.
19266 (insert_from_buffer_1, replace_range, replace_range_2):
19267 * insdel.c (make_gap_larger):
19268 * editfns.c (Finsert_char):
19269 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19271 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19273 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19275 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19277 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19278 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19280 * fileio.c: Don't assume EMACS_INT fits in off_t.
19281 (emacs_lseek): New static function.
19282 (Finsert_file_contents, Fwrite_region): Use it.
19283 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19285 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19287 * fns.c: Don't overflow int when computing a list length.
19288 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19289 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19290 truncation on 64-bit hosts. Check for QUIT every
19291 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19292 faster and is responsive enough.
19293 (Flength): Report an error instead of overflowing an integer.
19294 (Fsafe_length): Return a float if the value is not representable
19295 as a fixnum. This shouldn't happen except in contrived situations.
19296 (Fnthcdr, Fsort): Don't assume list length fits in int.
19297 (Fcopy_sequence): Don't assume vector length fits in int.
19299 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19300 (header_size, word_size): New constants.
19301 (allocate_vectorlike): Don't check size overflow here.
19302 (allocate_vector): Check it here instead, since this is the only
19303 caller of allocate_vectorlike that could cause overflow.
19304 Check that the new vector's length is representable as a fixnum.
19306 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19307 The previous code was bogus. For example, next_almost_prime (32)
19308 returned 39, which is undesirable as it is a multiple of 3; and
19309 next_almost_prime (24) returned 25, which is a multiple of 5 so
19310 why was the code bothering to check for multiples of 7?
19312 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19314 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19316 Variadic C functions now count arguments with ptrdiff_t.
19317 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19318 Back then I didn't know that the Emacs coding style prefers signed int.
19319 Also, in the meantime I found a few more instances where arguments
19320 were being counted with int, which may truncate counts on 64-bit
19321 machines, or EMACS_INT, which may be unnecessarily wide.
19322 * lisp.h (struct Lisp_Subr.function.aMANY)
19323 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19324 Arg counts are now ptrdiff_t, not size_t.
19325 All variadic functions and their callers changed accordingly.
19326 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19327 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19328 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19329 * callint.c (Fcall_interactively): Check arg count for overflow,
19330 to avoid potential buffer overrun. Use signed char, not 'int',
19331 for 'varies' array, so that we needn't bother to check its size
19332 calculation for overflow.
19333 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19334 * eval.c (apply_lambda):
19335 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19336 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19337 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19339 * callint.c (Fcall_interactively): Don't use index var as event count.
19341 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19342 * mem-limits.h (SIZE): Remove; no longer used.
19344 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19346 Remove unnecessary casts.
19347 * xterm.c (x_term_init):
19348 * xfns.c (x_set_border_pixel):
19349 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19350 These aren't needed now that we assume ANSI C.
19352 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19353 It's more likely to cause problems (due to unsigned overflow)
19356 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19358 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19360 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19362 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19364 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19366 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19368 GLYPH_CODE_FACE returns EMACS_INT, not int.
19369 * dispextern.h (merge_faces):
19370 * xfaces.c (merge_faces):
19371 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19372 Don't assume EMACS_INT fits in int.
19374 * character.h (CHAR_VALID_P): Remove unused parameter.
19375 * fontset.c, lisp.h, xdisp.c: All uses changed.
19377 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19379 * fns.c (concat): Minor tuning based on overflow analysis.
19380 This doesn't fix any bugs. Use int to hold character, instead
19381 of constantly refetching from Emacs object. Use XFASTINT, not
19382 XINT, for value known to be a character. Don't bother comparing
19383 a single byte to 0400, as it's always less.
19385 * floatfns.c (Fexpt):
19386 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19388 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19391 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19393 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19394 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19395 incorrectly succeed when S was a string, because 4294967386 was
19396 truncated before it was used.
19398 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19399 Otherwise, an out-of-range integer could cause undefined behavior
19402 * composite.c: Use int, not EMACS_INT, for characters.
19403 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19404 EMACS_INT, for values that are known to be in character range.
19405 This doesn't fix any bugs but is the usual style inside Emacs and
19406 may generate better code on 32-bit machines.
19408 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19409 This is for reasons similar to the recent CHAR_STRING fix.
19410 * charset.c (Fencode_char): Check that character arg is actually
19411 a character. Pass an int to ENCODE_CHAR.
19412 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19413 wider than 'int', as a compile-time check to prevent future regressions
19416 * character.c (char_string): Remove unnecessary casts.
19418 Make sure a 64-bit char is never passed to CHAR_STRING.
19419 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19420 by silently ignoring the top 32 bits, allowing some values
19421 that were far too large to be valid characters.
19422 * character.h: Include <verify.h>.
19423 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19424 arguments are no wider than unsigned, as a compile-time check
19425 to prevent future regressions in this area.
19427 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19428 (Fsubst_char_in_region):
19430 * xdisp.c (decode_mode_spec_coding):
19431 Adjust to CHAR_STRING's new requirement.
19432 * editfns.c (Finsert_char, Fsubst_char_in_region):
19433 * fns.c (concat): Check that character args are actually
19434 characters. Without this test, these functions did the wrong
19435 thing with wildly out-of-range values on 64-bit hosts.
19437 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19438 These casts should not be needed on 32-bit hosts, either.
19439 * keyboard.c (read_char):
19440 * lread.c (Fload): Remove casts to unsigned.
19442 * lisp.h (UNSIGNED_CMP): New macro.
19443 This fixes comparison bugs on 64-bit hosts.
19444 (ASCII_CHAR_P): Use it.
19445 * casefiddle.c (casify_object):
19446 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19447 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19448 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19449 * dispextern.h (FACE_FROM_ID):
19450 * keyboard.c (read_char): Use UNSIGNED_CMP.
19452 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19453 not to EMACS_INT, to avoid GCC warning.
19455 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19457 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19458 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19459 isn't needed on 32-bit machines.
19461 * buffer.c (Fgenerate_new_buffer_name):
19462 Use EMACS_INT for count, not int.
19463 (advance_to_char_boundary): Return EMACS_INT, not int.
19465 * data.c (Qcompiled_function): Now static.
19467 * window.c (window_body_lines): Now static.
19469 * image.c (gif_load): Rename local to avoid shadowing.
19471 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19472 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19473 * alloc.c (make_save_value): Integer argument is now of type
19474 ptrdiff_t, not int.
19475 (mark_object): Use ptrdiff_t, not int.
19476 * lisp.h (pD): New macro.
19477 * print.c (print_object): Use it.
19479 * alloc.c: Use EMACS_INT, not int, to count objects.
19480 (total_conses, total_markers, total_symbols, total_vector_size)
19481 (total_free_conses, total_free_markers, total_free_symbols)
19482 (total_free_floats, total_floats, total_free_intervals)
19483 (total_intervals, total_strings, total_free_strings):
19484 Now EMACS_INT, not int. All uses changed.
19485 (Fgarbage_collect): Compute overall total using a double, so that
19486 integer overflow is less likely to be a problem. Check for overflow
19487 when converting back to an integer.
19488 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19489 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19490 These were 'int' variables that could overflow on 64-bit hosts;
19491 they were never used, so remove them instead of repairing them.
19492 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19493 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19494 Previously, this ceilinged at INT_MAX, but that doesn't work on
19496 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19498 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19499 (allocate_vectorlike): Check for ptrdiff_t overflow.
19500 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19501 when a (possibly-narrower) signed value would do just as well.
19502 We prefer using signed arithmetic, to avoid comparison confusion.
19504 * alloc.c: Catch some string size overflows that we were missing.
19505 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19506 for convenience in STRING_BYTES_MAX.
19507 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19508 The definition here is exact; the one in lisp.h was approximate.
19509 (allocate_string_data): Check for string overflow. This catches
19510 some instances we weren't catching before. Also, it catches
19511 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19512 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19513 and ptrdiff_t and EMACS_INT are both 64 bits.
19515 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19516 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19517 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19519 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19521 * alloc.c (Fmake_string): Check for out-of-range init.
19523 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19525 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19527 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19529 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19530 xg_get_default_scrollbar_width.

20017 code. Minor doc-string fixes.
20019 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
20021 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
20022 Do not assume that spare memory exists; that assumption is valid
20023 only if SYSTEM_MALLOC.
20024 (LARGE_REQUEST): New macro, so that the issue of large requests
20025 is separated from the issue of spare memory.
20027 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
20029 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

20055 New error handlers.
20056 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
20057 Obey Vx_select_enable_clipboard_manager. Catch errors in

20081 (bidi_cache_search, bidi_cache_iterator_state)
20082 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
20083 (bidi_level_of_next_char, bidi_move_to_visually_next):
20084 Support character positions inside a run of characters covered by a
20086 (bidi_paragraph_init, bidi_resolve_explicit_1)
20087 (bidi_level_of_next_char): Call bidi_fetch_char and
20088 bidi_fetch_char_advance instead of FETCH_CHAR and

20091 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
20093 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
20094 instead of using explicit *_CHAR codes.
20095 (bidi_resolve_explicit, bidi_resolve_weak):
20096 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
20097 bidirectional text is supported only in multibyte buffers.
20098 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
20099 it to initialize the frame_window_p member of struct bidi_it.

20103 bidi_it->nchars is non-positive.
20104 (bidi_level_of_next_char): Don't try to lookup the cache for the
20105 next/previous character if nothing is cached there yet, or if we
20106 were just reseat()'ed to a new position.
20108 * xdisp.c (set_cursor_from_row): Set start and stop points
20109 according to the row's direction when priming the loop that looks
20110 for the glyph on which to display cursor.
20111 (single_display_spec_intangible_p): Function deleted.
20112 (display_prop_intangible_p): Reimplement to call
20113 handle_display_spec instead of single_display_spec_intangible_p.
20114 Accept 3 additional arguments needed by handle_display_spec.
20115 This fixes incorrect cursor motion across display property with complex
20116 values: lists, `(when COND...)' forms, etc.

20118 lists with the argument STRING its top-level element.
20119 (display_prop_string_p): Fix the condition for processing a
20120 property that is a list to be consistent with handle_display_spec.

20122 last portion of handle_display_prop.
20123 (compute_display_string_pos): Accept additional argument
20124 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20125 value of a `display' property is a "replacing spec".
20126 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20127 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20128 the display property, but just return a value indicating whether
20129 the display property will replace the characters it covers.
20130 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20131 frame_window_p members of struct bidi_it.
20132 (compute_display_string_pos, compute_display_string_end):
20134 (push_it): Accept second argument POSITION, where pop_it should
20135 jump to continue iteration.
20136 (reseat_1): Initialize bidi_it.disp_pos.
20138 * keyboard.c (adjust_point_for_property): Adjust the call to
20139 display_prop_intangible_p to its new signature.
20141 * dispextern.h (struct bidi_it): New member frame_window_p.
20142 (bidi_init_it): Update prototypes.

20152 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
20153 * lisp.h: Change signatures accordingly.
20154 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
20155 All callers changed. (Bug#8762)
20157 * gnutls.c: Use Emacs's memory allocators.
20158 Without this change, the gnutls library would invoke malloc etc.
20159 directly, which causes problems on non-SYNC_INPUT hosts, and which
20160 runs afoul of improving memory_full behavior. (Bug#8761)
20161 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20162 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20163 xfree instead of the default malloc, realloc, free.
20164 (Fgnutls_boot): No need to check for memory allocation failure,
20165 since xmalloc does that for us.
20167 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
20168 * category.c (hash_get_category_set):
20169 * ccl.c (ccl_driver):

20181 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
20182 (Fsxhash, Fgethash, Fputhash, Fmaphash):
20183 * image.c (make_image, search_image_cache, lookup_image)
20184 (xpm_put_color_table_h):
20185 * lisp.h (struct Lisp_Hash_Table):
20186 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20187 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20188 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20189 * alloc.c (allocate_vectorlike):
20190 Check for overflow in vector size calculations.
20191 * ccl.c (ccl_driver):
20192 Check for overflow when converting EMACS_INT to int.
20193 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20194 need to be updated by these changes.
20195 * fns.c (make_hash_table, maybe_resize_hash_table):
20196 Check for integer overflow with large hash tables.
20197 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20198 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20199 (SXHASH_REDUCE): New macro.
20200 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20201 Use it instead of discarding useful hash info with large hash values.
20202 (sxhash_float): New function.
20203 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20204 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20205 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20206 Rewrite to use FIXNUM_BITS, as this simplifies things.
20207 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20208 Adjust signatures to match updated version of code.
20209 (consing_since_gc): Now EMACS_INT, since a single hash table can
20210 use more than INT_MAX bytes.
20212 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20214 Make it possible to build with GCC-4.6+ -O2 -flto.
20216 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20218 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20220 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20221 Call minibuffer-inactive-mode.
20223 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20225 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20226 Update dependencies.
20228 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20230 * data.c (init_data): Remove code for UTS, this system is not
20233 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20235 Don't force ./temacs to start in terminal mode.
20237 * frame.c (make_initial_frame): Initialize faces in all cases, not
20238 only when CANNOT_DUMP is defined.
20239 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20241 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20243 * dispnew.c (add_window_display_history): Use const for the string
20244 pointer. Remove declaration, not needed.
20246 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20248 Use 'inline', not 'INLINE'.
20249 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20250 * alloc.c, fontset.c (INLINE): Remove.
20251 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20252 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20253 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20254 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20255 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20257 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20259 Make it possible to run ./temacs.
20261 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20262 syms_of_callproc does the same thing. Remove test for
20263 "initialized", do it in the caller.
20264 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20266 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20268 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20269 (read_minibuf): Use get_minibuffer.
20270 (syms_of_minibuf): Use DEFSYM.
20271 (Qmetadata): New var.
20272 * data.c (Qbuffer): Don't make it static.
20273 (syms_of_data): Use DEFSYM.
20275 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20277 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20278 (CCL_CODE_MIN): New macro.
20280 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20282 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20284 * eval.c (Qdebug): Now static.
20285 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20286 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20287 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20289 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20291 * image.c: Various fixes to ImageMagick code comments.
20292 (Fimagemagick_types): Doc fix.
20294 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20296 Minor fixes prompted by GCC 4.6.0 warnings.
20298 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20300 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20301 (x_clipboard_manager_save_all): Move extern decl to ...
20302 * xterm.h: ... here, so that it can be checked for consistency.
20304 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20306 * xselect.c (x_clipboard_manager_save_frame)
20307 (x_clipboard_manager_save_all): New functions.
20308 (Fx_clipboard_manager_save): Lisp function deleted.
20310 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20311 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20313 * xterm.h: Update prototype.
20315 2011-05-28 William Xu <william.xwl@gmail.com>
20317 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20318 exiting (Bug#8239).
20320 2011-05-28 Jim Meyering <meyering@redhat.com>
20322 Avoid a sign-extension bug in crypto_hash_function.
20323 * fns.c (to_uchar): Define.
20324 (crypto_hash_function): Use it to convert some newly-signed
20325 variables to unsigned, to avoid sign-extension bugs. For example,
20326 without this change, (md5 "truc") would evaluate to
20327 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20328 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20329 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20331 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20333 Integer overflow fixes.
20335 * dbusbind.c: Serial number integer overflow fixes.
20336 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20337 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20338 to hold a serial number that is too large for a fixnum.
20339 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20340 Check for serial numbers out of range. Decode any serial number
20341 that was so large that it became a float. (Bug#8722)
20343 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20344 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20345 Use XFASTINT rather than XUINT when numbers are nonnegative.
20346 (xd_append_arg, Fdbus_method_return_internal):
20347 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20348 arguments, check that Lisp number is nonnegative, rather than
20349 silently wrapping negative numbers around. (Bug#8722)
20350 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20353 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20355 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20357 ccl: Add integer overflow checks.
20358 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20359 (IN_INT_RANGE): New macros.
20360 (ccl_driver): Use them to check for integer overflow when
20361 decoding a CCL program. Many of the new checks are whether XINT (x)
20362 fits in int; it doesn't always, on 64-bit hosts. The new version
20363 doesn't catch all possible integer overflows, but it's an
20364 improvement. (Bug#8719)
20366 * alloc.c (make_event_array): Use XINT, not XUINT.
20367 There's no need for unsigned here.
20369 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20370 This follows up to the 2011-05-06 change that substituted uintptr_t
20371 for EMACS_INT. This case wasn't caught back then.
20373 Rework Fformat to avoid integer overflow issues.
20374 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20375 now (part of C89). Include <verify.h>.
20376 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20377 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20378 (Fformat): Avoid the prepass trying to compute sizes; it was only
20379 approximate and thus did not catch overflow reliably. Instead, walk
20380 through the format just once, formatting and computing sizes as we go,
20381 checking for integer overflow at every step, and allocating a larger
20382 buffer as needed. Keep track separately whether the format is
20383 multibyte. Keep only the most-recently calculated precision, rather
20384 than them all. Record whether each argument has been converted to
20385 string. Use EMACS_INT, not int, for byte and char and arg counts.
20386 Support field widths and precisions larger than INT_MAX. Avoid
20387 sprintf's undefined behavior with conversion specifications such as %#d
20388 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20389 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20390 formatting out-of-range floating point numbers with int
20391 formats. (Bug#8668)
20393 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20395 * data.c: Avoid integer truncation in expressions involving floats.
20396 * data.c: Include <intprops.h>.
20397 (arith_driver): When there's an integer overflow in an expression
20398 involving floating point, convert the integers to floating point
20399 so that the resulting value does not suffer from catastrophic
20400 integer truncation. For example, on a 64-bit host (* 4
20401 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20402 Do not rely on undefined behavior after integer overflow.
20404 merge count_size_as_multibyte, parse_str_to_multibyte
20405 * character.c, character.h (count_size_as_multibyte):
20406 Rename from parse_str_to_multibyte; all uses changed.
20407 Check for integer overflow.
20408 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20409 since it's now a duplicate of the other. This is more of
20410 a character than a buffer op, so better that it's in character.c.
20411 * fns.c, print.c: Adjust to above changes.
20413 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20415 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20417 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20419 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20420 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20421 (x_clipboard_manager_save): Now static.
20422 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20424 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20425 (crypto_hash_function): Now static.
20426 Fix pointer signedness problems. Avoid unnecessary initializations.
20428 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20430 * termhooks.h (Vselection_alist): Make it terminal-local.
20432 * terminal.c (create_terminal): Initialize it.
20434 * xselect.c: Support for clipboard managers.
20435 (Vselection_alist): Move to termhooks.h as terminal-local var.
20436 (LOCAL_SELECTION): New macro.
20437 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20438 (symbol_to_x_atom): Remove gratuitous arg.
20439 (x_handle_selection_request, lisp_data_to_selection_data)
20440 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20441 (x_own_selection, x_get_local_selection, x_convert_selection):
20442 New arg, specifying work frame. Use terminal-local Vselection_alist.
20443 (some_frame_on_display): Delete unused function.
20444 (Fx_own_selection_internal, Fx_get_selection_internal)
20445 (Fx_disown_selection_internal, Fx_selection_owner_p)
20446 (Fx_selection_exists_p): New optional frame arg.
20447 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20448 (x_handle_selection_clear): Don't treat other terminals with the
20449 same keyboard specially. Use the terminal-local Vselection_alist.
20450 (x_clear_frame_selections): Use Frun_hook_with_args.
20452 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20454 * xterm.h: Add support for those atoms.
20456 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20458 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20459 (converted_selections, conversion_fail_tag): New global variables.
20460 (x_selection_request_lisp_error): Free the above.
20461 (x_get_local_selection): Remove unnecessary code.
20462 (x_reply_selection_request): Args changed; handle arbitrary array
20463 of converted selections stored in converted_selections.
20464 Separate the XChangeProperty and SelectionNotify steps.
20465 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20466 (x_convert_selection): New function.
20467 (x_handle_selection_event): Simplify.
20468 (x_get_foreign_selection): Don't ignore incoming requests while
20469 waiting for an answer; this will fail when we implement
20470 SAVE_TARGETS, and seems unnecessary anyway.
20471 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20472 (Vx_sent_selection_functions): Doc fix.
20474 2011-05-26 Leo Liu <sdl.web@gmail.com>
20476 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20478 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20480 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20482 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20483 for fringe update if it has periodic bitmap.
20484 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20485 and fringe_bitmap_periodic_p.
20487 * fringe.c (get_fringe_bitmap_data): New function.
20488 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20489 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20490 row. Mark glyph row for fringe update if periodicity changed.
20492 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20493 for fringe update unless it has periodic bitmap.
20495 2011-05-25 Kenichi Handa <handa@m17n.org>
20497 * xdisp.c (get_next_display_element): Set correct it->face_id for
20498 a static composition.
20500 2011-05-24 Leo Liu <sdl.web@gmail.com>
20503 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20505 * fns.c (crypto_hash_function, Fsha1): New function.
20506 (Fmd5): Use crypto_hash_function.
20507 (syms_of_fns): Add Ssha1.
20509 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20511 * gnutls.c: Remove unused macros.
20512 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20513 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20514 Remove macros that are defined and never used.
20515 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20517 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20519 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20520 (Fx_get_selection_internal): Minor cleanup.
20521 (Fx_own_selection_internal): Rename arguments for consistency with
20524 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20526 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20528 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20530 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20532 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20534 * dispnew.c (scrolling_window): Don't exclude the case that the
20535 last enabled row in the desired matrix touches the bottom boundary.
20537 2011-05-21 Glenn Morris <rgm@gnu.org>
20539 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20540 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20541 and add some more files.
20543 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20545 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20546 report_file_error introduced by the change from 2011-05-07.
20548 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20550 * systime.h (Time): Define only if emacs is defined.
20551 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20552 where the include path doesn't have X11/X.h by default. See
20553 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20555 2011-05-20 Kenichi Handa <handa@m17n.org>
20557 * composite.c (find_automatic_composition): Fix previous change.
20559 2011-05-20 Glenn Morris <rgm@gnu.org>
20561 * lisp.mk: New file, split from Makefile.in.
20562 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20563 (shortlisp): Remove.
20564 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20566 2011-05-19 Glenn Morris <rgm@gnu.org>
20568 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20569 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20570 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20571 (lisp): Set the order to that of loadup.el.
20572 (shortlisp): Make it a copy of $lisp.
20573 (SOME_MACHINE_LISP): Remove.
20574 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20575 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20577 2011-05-18 Kenichi Handa <handa@m17n.org>
20579 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20580 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20581 (find_automatic_composition): Mostly rewrite for efficiency.
20583 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20585 * makefile.w32-in: Update dependencies.
20587 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20589 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20590 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20592 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20594 Fix some integer overflow issues, such as string length overflow.
20596 * insdel.c (count_size_as_multibyte): Check for string overflow.
20598 * character.c (lisp_string_width): Check for string overflow.
20599 Use EMACS_INT, not int, for string indexes and lengths; in
20600 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20601 the resulting string length overflows an EMACS_INT; instead,
20602 report a string overflow if no precision given. When checking for
20603 precision exhaustion, use a check that cannot possibly have
20604 integer overflow. (Bug#8675)
20605 * character.h (lisp_string_width): Adjust to new signature.
20607 * alloc.c (string_overflow): New function.
20608 (Fmake_string): Use it. This doesn't change behavior, but saves
20609 a few bytes and will simplify future changes.
20610 * character.c (string_escape_byte8): Likewise.
20611 * lisp.h (string_overflow): New decl.
20613 Fixups, following up to the user-interface timestamp change.
20614 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20615 for UI timestamps, instead of unsigned long.
20616 * msdos.c (mouse_get_pos): Likewise.
20617 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20618 * w32gui.h (Time): Define by including "systime.h" rather than by
20619 declaring it ourselves. (Bug#8664)
20621 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20622 * image.c (clear_image_cache): Likewise.
20624 * term.c (term_mouse_position): Don't assume time_t wraparound.
20626 Be more systematic about user-interface timestamps.
20627 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20628 and sometimes 'EMACS_UINT', to represent these timestamps.
20629 This change causes it to use 'Time' uniformly, as that's what X uses.
20630 This makes the code easier to follow, and makes it easier to catch
20631 integer overflow bugs such as Bug#8664.
20632 * frame.c (Fmouse_position, Fmouse_pixel_position):
20633 Use Time, not unsigned long, for user-interface timestamps.
20634 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20635 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20636 * keyboard.h (last_event_timestamp): Likewise.
20637 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20638 * menu.h (xmenu_show): Likewise.
20639 * term.c (term_mouse_position): Likewise.
20640 * termhooks.h (struct input_event.timestamp): Likewise.
20641 (struct terminal.mouse_position_hook): Likewise.
20642 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20643 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20644 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20645 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20646 what it was before.
20647 * menu.h, termhooks.h: Include "systime.h", for Time.
20649 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20650 Don't assume that the difference between two unsigned long values
20651 can fit into an integer. At this point, we know button_down_time
20652 <= event->timestamp, so the difference must be nonnegative, so
20653 there's no need to cast the result if double-click-time is
20654 nonnegative, as it should be; check that it's nonnegative, just in
20655 case. This bug is triggered when events are more than 2**31 ms
20656 apart (about 25 days). (Bug#8664)
20658 * xselect.c (last_event_timestamp): Remove duplicate decl.
20659 (x_own_selection): Remove needless cast to unsigned long.
20661 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20662 that always fit in int. Use a sentinel instead of a counter, to
20663 avoid a temp and to allay GCC's concerns about possible int overflow.
20664 * frame.h (struct frame): Use int for menu_bar_items_used
20665 instead of EMACS_INT, since it always fits in int.
20667 * menu.c (grow_menu_items): Check for int overflow.
20669 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20671 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20672 Before, the code was not consistent. These values cannot exceed
20673 2**31 - 1 so there's no need to make them unsigned.
20674 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20675 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20676 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20678 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20680 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20681 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20682 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20683 presumably because the widths might not match.
20685 * window.c (size_window): Avoid needless test at loop start.
20687 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20689 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20691 2011-05-12 Drew Adams <drew.adams@oracle.com>
20693 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20695 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20697 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20698 `width' to `bar_area_x' and `bar_area_width', respectively.
20699 (x_scroll_run): Take account of fringe background extension.
20701 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20702 Rename local vars `left' and `width' to `bar_area_x' and
20703 `bar_area_width', respectively.
20704 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20705 background extension.
20707 2011-05-10 Jim Meyering <meyering@redhat.com>
20709 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20711 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20713 * image.c (Finit_image_library): Return t for built-in image types,
20714 like pbm and xbm. (Bug#8640)
20716 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20718 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20720 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20722 * w32console.c (Fset_screen_color): Doc fix.
20723 (Fget_screen_color): New function.
20724 (syms_of_ntterm): Defsubr it.
20726 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20727 unlink the temporary file if Fcall_process didn't create it in the
20729 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20730 child process will be redirected to a file specified with `:file'.
20731 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20732 cue to call_process_cleanup not to close that handle.
20734 2011-05-07 Ben Key <bkey76@gmail.com>
20736 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20737 one of two shell specific rules, either bootstrap-temacs-CMD or
20738 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20739 to the previous implementation of the bootstrap-temacs rule.
20740 The bootstrap-temacs-CMD rule is similar to the previous
20741 implementation of the bootstrap-temacs rule except that it
20742 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20745 These changes, along with some changes to nt/configure.bat,
20746 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20747 earlier fix to add support for --cflags and --ldflags options
20748 that include quotes so that it works whether make uses cmd or
20751 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20753 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20754 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20756 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20757 a string. Handle both cases.
20758 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20759 (Fdbus_register_method): Use Qinvalid_function.
20761 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20763 * makefile.w32-in: Update dependencies.
20764 (LISP_H): Add inttypes.h and stdin.h.
20765 (PROCESS_H): Add unistd.h.
20767 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20769 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20770 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20772 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20774 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20776 * term.c (vfatal): Remove stray call to va_end.
20777 It's not needed and the C Standard doesn't allow it here anyway.
20779 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20780 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20782 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20785 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20787 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20789 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20791 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20793 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20795 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20796 * charset.c (Fdefine_charset_internal): Don't initialize
20797 charset.code_space[15]. The value was garbage, on hosts with
20798 32-bit int (Bug#8600).
20800 * lread.c (read_integer): Be more consistent with string-to-number.
20801 Use string_to_number to do the actual conversion; this avoids
20802 rounding errors and fixes some other screwups. Without this fix,
20803 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20804 (digit_to_number): Move earlier, for benefit of read_integer.
20805 Return -1 if the digit is out of range for the base, -2 if it is
20806 not a digit in any supported base. (Bug#8602)
20808 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20810 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20811 to match comment at start of function. This also removes a
20812 GCC warning about overflow in a 32+64-bit port.
20814 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20816 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20817 Reported by Stefan Monnier in
20818 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20819 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20820 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20822 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20823 (EMACS_UINTPTR): Likewise, with uintptr_t.
20825 * lisp.h: Prefer 64-bit EMACS_INT if available.
20826 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20827 on 32-bit hosts that have 64-bit int, so that they can access
20829 However, temporarily disable this change unless the temporary
20830 symbol WIDE_EMACS_INT is defined.
20832 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20834 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20835 This removes an assumption that EMACS_INT and long are the same
20836 width as pointers. The assumption is true for Emacs porting targets
20837 now, but we want to make other targets possible.
20838 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20839 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20840 In the rest of the code, change types of integers that hold casted
20841 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20842 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20843 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20844 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20845 No need to cast type when ORing.
20846 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20847 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20848 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20849 assume EMACS_INT is the same width as char *.
20850 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20851 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20852 Remove no-longer-needed casts.
20853 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20854 (xg_tool_bar_help_callback, xg_make_tool_item):
20855 Use EMACS_INTPTR to hold an integer
20856 that will be cast to void *; this can avoid a GCC warning
20857 if EMACS_INT is not the same width as void *.
20858 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20859 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20860 (current_message_1, set_message_1):
20861 Use a local to convert to proper width without a cast.
20862 * xmenu.c (dialog_selection_callback): Likewise.
20864 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20865 Also, don't assume VALBITS / RAND_BITS is less than 5,
20866 and don't rely on undefined behavior when shifting a 1 left into
20868 * lisp.h (get_random): Change signature to match.
20870 * lread.c (hash_string): Use size_t, not int, for hash computation.
20871 Normally we prefer signed values; but hashing is special, because
20872 it's better to use unsigned division on hash table sizes so that
20873 the remainder is nonnegative. Also, size_t is the natural width
20874 for hashing into memory. The previous code used 'int', which doesn't
20875 retain enough info to hash well into very large tables.
20876 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20878 * dbusbind.c: Don't possibly lose pointer info when converting.
20879 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20880 Use XPNTR rather than XHASH, so that the high-order bits of
20881 the pointer aren't lost when converting through void *.
20883 * eval.c (Fautoload): Don't double-shift a pointer.
20885 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20887 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20889 * gnutls.c (DEF_GNUTLS_FN):
20890 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20892 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20894 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20897 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20899 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:

20916 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20918 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20919 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20920 Remove unused parameter `fildes'.
20921 * process.c (read_process_output, send_process): Don't pass it.
20923 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20925 Fix previous change: the library cache is defined in w32.c.
20926 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20927 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20929 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20931 Implement dynamic loading of GnuTLS on Windows.

20947 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20948 (Fgnutls_available_p): New function.
20949 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

20961 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20962 (w32_delayed_load): Move from image.c. When loading a library, record
20963 its filename in the :loaded-from property of the library id.
20964 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20965 Initialize and staticpro them.
20966 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20968 * process.c: Include lisp.h before w32.h, not after.
20969 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20970 instead of gnutls_record_check_pending.
20972 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20974 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20976 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20977 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20980 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20982 * xterm.c (x_set_frame_alpha): Do not set property on anything
20983 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20985 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20987 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20989 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20991 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

21011 * sysdep.c (interruptible_wait_for_termination): New function
21012 which is like wait_for_termination, but allows keyboard
21015 * callproc.c (Fcall_process): Add (:file "file") as an option for
21017 (Fcall_process_region): Ditto.
21019 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21021 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21022 rather than `XVECTOR (FOO)->size'.
21024 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21025 inttypes.h, as a gnulib replacement is used if it not available in
21028 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21030 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21031 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21032 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21034 * coding.c (coding_alloc_by_realloc): Error out if destination
21035 will grow beyond MOST_POSITIVE_FIXNUM.
21036 (decode_coding_emacs_mule): Abort if there isn't enough place in
21037 charbuf for the composition carryover bytes. Reserve an extra
21038 space for up to 2 characters produced in a loop.
21039 (decode_coding_iso_2022): Abort if there isn't enough place in
21040 charbuf for the composition carryover bytes.
21042 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21044 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
21045 aborting when %lld or %lll format is passed.
21046 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21047 %llo or %llx format is passed. (Bug#8545)
21049 * window.c (window_scroll_line_based): Use a marker instead of
21050 simple variables to record original value of point. (Bug#7952)
21052 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21053 produced by %s or %c overflows available buffer space. (Bug#8545)
21055 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21057 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21058 (SIZE_MAX): Move defn after all includes, as they might #define it.
21060 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

21066 * keyboard.c (Qdelayed_warnings_hook): Define.
21067 (command_loop_1): Run `delayed-warnings-hook'
21068 if Vdelayed_warnings_list is non-nil.
21069 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21070 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21072 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21074 * doprnt.c (doprnt): Don't return value smaller than the buffer
21075 size if the message was truncated. (Bug#8545).
21077 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21079 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21080 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21082 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21084 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21086 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21088 * makefile.w32-in: Update dependencies.
21090 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21092 Improve `doprnt' and its usage. (Bug#8545)
21093 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21094 `format_end'. Remove support for %l as a conversion specifier.
21095 Don't use xrealloc. Improve diagnostics when the %l size modifier
21096 is used. Update the commentary.
21098 * eval.c (verror): Simplify calculation of size_t.
21100 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21103 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21105 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21108 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21110 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21111 This makes this file independent of the recent pseudovector change.
21113 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21115 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21117 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21118 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21119 Remove unused local.
21120 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21122 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21123 GCC 4.6.0 optimizes based on type-based alias analysis.
21124 For example, if b is of type struct buffer * and v of type struct
21125 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21126 != &v->size, and therefore "v->size = 1; b->size = 2; return
21127 v->size;" must therefore return 1. This assumption is incorrect
21128 for Emacs, since it type-puns struct Lisp_Vector * with many other
21129 types. To fix this problem, this patch adds a new type struct
21130 vectorlike_header that documents the constraints on layout of vectors
21131 and pseudovectors, and helps optimizing compilers not get fooled
21132 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21133 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21134 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21136 (XSETPVECTYPE): Rewrite in terms of new macro.
21137 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21138 This is a bit clearer, and further avoids the possibility of
21139 undesirable aliasing.
21140 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21141 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21142 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21143 since Lisp_Subr is a special case (no "next" field).
21144 (ASIZE): Now uses header.size rather than size.
21145 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21146 to avoid the hassle of writing XVECTOR (foo)->header.size.
21147 (struct vectorlike_header): New type.
21148 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21149 object, to help avoid aliasing.
21150 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21151 (SUBRP): Likewise, since Lisp_Subr is a special case.
21152 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21153 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21154 (struct Lisp_Hash_Table): Combine first two members into a single
21155 struct vectorlike_header member. All uses of "size" and "next" members
21156 changed to be "header.size" and "header.next".
21157 * buffer.h (struct buffer): Likewise.
21158 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21159 * frame.h (struct frame): Likewise.
21160 * process.h (struct Lisp_Process): Likewise.
21161 * termhooks.h (struct terminal): Likewise.
21162 * window.c (struct save_window_data, struct saved_window): Likewise.
21163 * window.h (struct window): Likewise.
21164 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21165 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21166 * buffer.c (init_buffer_once): Likewise.
21167 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21169 * process.c (Fformat_network_address): Use local var for size,
21172 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21174 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21175 * data.c (atof): Remove decl; no longer used or needed.
21176 (digit_to_number): Move to lread.c.
21177 (Fstring_to_number): Use new string_to_number function, to be
21178 consistent with how the Lisp reader treats infinities and NaNs.
21179 Do not assume that floating-point numbers represent EMACS_INT
21180 without losing information; this is not true on most 64-bit hosts.
21181 Avoid double-rounding errors, by insisting on integers when
21182 parsing non-base-10 numbers, as the documentation specifies.
21183 * lisp.h (string_to_number): New decl, replacing ...
21184 (isfloat_string): Remove.
21185 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21186 (read1): Do not accept +. and -. as integers; this
21187 appears to have been a coding error. Similarly, do not accept
21188 strings like +-1e0 as floating point numbers. Do not report
21189 overflow for integer overflows unless the base is not 10 which
21190 means we have no simple and reliable way to continue.
21191 Break out the floating-point parsing into a new
21192 function string_to_number, so that Fstring_to_number parses
21193 floating point numbers consistently with the Lisp reader.
21194 (digit_to_number): Move here from data.c. Make it static inline.
21195 (E_CHAR, EXP_INT): Remove, replacing with ...
21196 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21197 (string_to_number): New function, replacing isfloat_string.
21198 This function checks for valid syntax and produces the resulting
21199 Lisp float number too. Rework it so that string-to-number
21200 no longer mishandles examples like "1.0e+". Use strtoumax,
21201 so that overflow for non-base-10 numbers is reported only when
21202 there's no portable and simple way to convert to floating point.
21204 * textprop.c (set_text_properties_1): Rewrite for clarity,
21205 and to avoid GCC warning about integer overflow.
21207 * intervals.h (struct interval): Use EMACS_INT for members
21208 where EMACS_UINT might cause problems. See
21209 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21210 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21211 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21213 (offset_intervals): Tell GCC not to worry about length overflow
21214 when negating a negative length.
21216 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21217 (overrun_check_free): Likewise.
21219 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21220 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21223 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21224 (gnutls_make_error): Rename local to avoid shadowing.
21225 (gnutls_emacs_global_deinit): ifdef out; not used.
21226 (Fgnutls_boot): Use const for pointer to readonly storage.
21227 Comment out unused local. Fix pointer signedness problems.
21229 * lread.c (openp): Don't stuff size_t into an 'int'.
21230 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21231 about possible signed overflow.
21233 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21234 (GDK_KEY_g): Don't define if already defined.
21235 (xg_prepare_tooltip): Avoid pointer signedness problem.
21236 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21238 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21239 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21241 * xfns.c (Fx_window_property): Simplify a bit,
21242 to make a bit faster and to avoid GCC 4.6.0 warning.
21243 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21245 * fns.c (internal_equal): Don't assume size_t fits in int.
21247 * alloc.c (compact_small_strings): Tighten assertion a little.
21249 Replace pEd with more-general pI, and fix some printf arg casts.
21250 * lisp.h (pI): New macro, generalizing old pEd macro to other
21251 conversion specifiers. For example, use "...%"pI"d..." rather
21252 than "...%"pEd"...".
21253 (pEd): Remove. All uses replaced with similar uses of pI.
21254 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21255 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21256 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.

21258 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21259 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21260 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21262 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21263 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21264 * print.c (safe_debug_print, print_object): Likewise.
21265 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21267 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21268 avoiding the 0 flag, which is not portable.

21270 * region-cache.c (pp_cache): Likewise.
21271 * xdisp.c (decode_mode_spec): Likewise.

21276 (x_get_window_property): Don't truncate byte count to an 'int'
21279 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21280 here, since it parses constructs like leading '-' and spaces,
21281 which are not wanted; and it overflows with large numbers.
21282 Instead, simply match F[0-9]+, which is what is wanted anyway.
21284 * alloc.c: Remove unportable assumptions about struct layout.
21285 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21286 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21287 (allocate_vectorlike, make_pure_vector): Use the new macros,
21288 plus offsetof, to remove unportable assumptions about struct layout.
21289 These assumptions hold on all porting targets that I know of, but
21290 they are not guaranteed, they're easy to remove, and removing them
21291 makes further changes easier.
21293 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21294 This doesn't fix a bug but makes the code clearer.
21295 (string_overrun_cookie): Now const. Use initializers that
21296 don't formally overflow signed char, to avoid warnings.
21297 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21298 can cause Emacs to crash when string overrun checking is enabled.
21299 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21300 multiple of sizeof (EMACS_INT); it need not be, if
21301 alignof(EMACS_INT) < sizeof (EMACS_INT).
21302 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

21333 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21334 "cast to pointer from integer of different size".
21336 Improve doprnt and its use in verror. (Bug#8545)
21337 * doprnt.c (doprnt): Document the set of format control sequences
21338 supported by the function. Use SAFE_ALLOCA instead of always
21341 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21342 is one byte too soon. Don't use xrealloc; instead xfree and

21354 docstring. Start callback support.
21355 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21356 unless a fatal error occurred. Call gnutls_alert_send_appropriate

21460 codepoint of an invalid character, to avoid displaying a bogus
21463 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21464 `error', not SYMBOL_NAME itself.
21466 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

21469 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21470 to `error' in error message about FINAL_CHAR argument. Make sure
21471 FINAL_CHAR is a character, and use %c when it is passed as
21472 argument to `error'.
21474 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21476 * s/ms-w32.h (localtime): Redirect to sys_localtime.
21478 * w32.c: Include <time.h>.

21542 * dispextern.h (struct redisplay_interface): Rename param
21543 to avoid shadowing.
21544 * termhooks.h (struct terminal): Likewise.
21545 * xterm.c (xembed_send_message): Likewise.

21661 * nsfont.m: Fixed bugs in ns_get_family and
21662 ns_descriptor_to_entity that were caused by using free to
21663 deallocate memory blocks that were allocated by xmalloc (via
21664 xstrdup). This caused Emacs to crash when compiled with
21665 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21666 --enable-checking=xmallocoverrun). xfree is now used to
21667 deallocate these memory blocks.

21681 (emacs_read, emacs_write): Remove check for negative size, as the
21682 Emacs source code has been audited now.
21683 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
21684 (emacs_read, emacs_write): Use it.
21685 * process.c (send_process): Adjust to the new signatures of
21686 emacs_write and emacs_gnutls_write. Do not attempt to store
21687 a byte offset into an 'int'; it might overflow.
21688 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

22137 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22138 when at ZV. (Bug#8487)
22140 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22142 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22144 * keyboard.c (parse_tool_bar_item): Likewise.
22145 * sound.c (sound_cleanup, alsa_close): Likewise.
22146 * termcap.c (tgetent): Likewise.
22147 * xfns.c (x_default_font_parameter): Likewise.
22148 * xsettings.c (read_and_apply_settings): Likewise.
22150 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22151 (overrun_check_free): Protoize.
22153 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22155 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22156 since callers should never pass a negative size.
22157 Change the signature to match that of plain 'read' and 'write'; see
22158 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22159 * lisp.h: Update prototypes of emacs_write and emacs_read.
22161 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22163 * xdisp.c (redisplay_window): Don't try to determine the character
22164 position of the scroll margin if the window start point w->startp
22165 is outside the buffer's accessible region. (Bug#8468)
22167 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22169 Fix write-region and its subroutines for buffers > 2GB.
22170 * fileio.c (a_write, e_write): Modify declaration of arguments and
22171 local variables to support buffers larger than 2GB.
22172 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22174 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22175 argument, local variables, and return value.
22177 * lisp.h: Update prototypes of emacs_write and emacs_read.
22179 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22181 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22183 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22185 Fix more problems found by GCC 4.6.0's static checks.
22187 * xdisp.c (vmessage): Use a better test for character truncation.
22189 * charset.c (load_charset_map): <, not <=, for optimization,
22190 and to avoid potential problems with integer overflow.
22191 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22192 * casetab.c (set_identity, shuffle): Likewise.
22193 * editfns.c (Fformat): Likewise.
22194 * syntax.c (skip_chars): Likewise.
22196 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22197 This also lets GCC 4.6.0 generate slightly better loop code.
22199 * callint.c (Fcall_interactively): <, not <=, for optimization.
22200 (Fcall_interactively): Count the number of arguments produced,
22201 not the number of arguments given. This is simpler and lets GCC
22202 4.6.0 generate slightly better code.
22204 * ftfont.c: Distingish more carefully between FcChar8 and char.
22205 The previous code passed unsigned char * to a functions like
22206 strlen and xstrcasecmp that expect char *, which does not
22207 conform to the C standard.
22208 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22209 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22210 char * when the C standard requires it.
22212 * keyboard.c (read_char): Remove unused var.
22214 * eval.c: Port to Windows vsnprintf (Bug#8435).
22215 Include <limits.h>.
22216 (SIZE_MAX): Define if the headers do not.
22217 (verror): Do not give up if vsnprintf returns a negative count.
22218 Instead, grow the buffer. This ports to Windows vsnprintf, which
22219 does not conform to C99. Problem reported by Eli Zaretskii.
22220 Also, simplify the allocation scheme, by avoiding the need for
22221 calling realloc, and removing the ALLOCATED variable.
22223 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22225 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22226 But keep the doprint source code for now, as we might revamp it
22227 and use it again (Bug#8435).
22228 * lisp.h (doprnt): Remove.
22229 * Makefile.in (base_obj): Remove doprnt.o.
22230 * deps.mk (doprnt.o): Remove.
22232 error: Print 32- and 64-bit integers portably (Bug#8435).
22233 Without this change, on typical 64-bit hosts error ("...%d...", N)
22234 was used to print both 32- and 64-bit integers N, which relied on
22235 undefined behavior.
22236 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22237 * lisp.h (error, verror): Mark as printf-like functions.
22238 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22239 Report overflow in size calculations when allocating printf buffer.
22240 Do not truncate output string at its first null byte.
22241 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22242 Truncate the output at a character boundary, since vsnprintf does not
22244 * charset.c (check_iso_charset_parameter): Convert internal
22245 character to string before calling 'error', since %c now has the
22247 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22248 overflow when computing char to be passed to 'error'. Do not
22249 pass Lisp_Object to 'error'; pass the integer instead.
22250 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22251 formatted with plain %d.
22253 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22255 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22257 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22259 * xterm.c (x_catch_errors): Remove duplicate declaration.
22261 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22263 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22265 2011-04-10 Jim Meyering <meyering@redhat.com>
22267 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22268 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22269 return ssize_t not "int", and use size_t as the buffer length.
22270 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22271 * gnutls.h: Update declarations.
22272 * process.c (read_process_output): Use ssize_t, to match.
22273 (send_process): Likewise.
22275 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22277 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22279 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22281 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22282 Use unsigned char, to match FcChar8 type definition.
22284 * xterm.c (handle_one_xevent):
22285 * xmenu.c (create_and_show_popup_menu):
22286 * xselect.c (x_decline_selection_request)
22287 (x_reply_selection_request): Avoid type-punned deref of X events.
22289 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22291 Fix some uses of `int' instead of EMACS_INT.
22292 * search.c (string_match_1, fast_string_match)
22293 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22294 (scan_buffer, find_next_newline_no_quit)
22295 (find_before_next_newline, search_command, Freplace_match)
22296 (Fmatch_data): Make some `int' variables be EMACS_INT.
22298 * xdisp.c (display_count_lines): 3rd argument and return value now
22299 EMACS_INT. All callers changed.
22300 (pint2hrstr): Last argument is now EMACS_INT.
22302 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22303 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22304 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22305 (decode_coding_utf_16, decode_coding_emacs_mule)
22306 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
22307 (decode_coding_ccl, decode_coding_charset)
22308 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22309 (decode_coding_iso_2022, decode_coding_emacs_mule)
22310 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22311 <char_offset, last_offset>: Declare EMACS_INT.
22312 (encode_coding_utf_8, encode_coding_utf_16)
22313 (encode_coding_emacs_mule, encode_invocation_designation)
22314 (encode_designation_at_bol, encode_coding_iso_2022)
22315 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22316 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22318 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22319 (encode_invocation_designation): Last argument P_NCHARS is now
22321 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22322 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22324 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22327 * ccl.c (Fccl_execute_on_string): Declare some variables
22330 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22332 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22334 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22336 * process.c (Fformat_network_address): Doc fix.
22338 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22340 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22342 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22344 * keyboard.c (read_char): Call Lisp function help-form-show,
22345 instead of using internal_with_output_to_temp_buffer.
22346 (Qhelp_form_show): New var.
22347 (syms_of_keyboard): Use DEFSYM macro.
22349 * print.c (internal_with_output_to_temp_buffer): Function deleted.
22351 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
22353 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22355 * process.c (Flist_processes): Remove to Lisp.
22356 (list_processes_1): Delete.
22358 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22360 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22362 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22364 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22366 Fix more problems found by GCC 4.6.0's static checks.
22368 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22370 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22372 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22374 * xdisp.c (vmessage): Mark as a printf-like function.
22376 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22378 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22380 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22381 printf-like functions.
22382 (tiff_load): Add casts to remove these marks before passing them
22383 to system-supplied API.
22385 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22387 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22388 This avoids several warnings with gcc -Wstrict-overflow.
22389 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22390 directly, rather than having caller test rule sign. This avoids
22391 some unnecessary tests.
22392 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22393 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22394 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22396 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22397 (xfont_open): Avoid unnecessary tests.
22399 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22401 * composite.h, composite.c (composition_gstring_put_cache):
22402 Use EMACS_INT, not int, for length.

22405 breaking out part of COMPOSITION_DECODE_RULE.
22406 (COMPOSITION_DECODE_RULE): Use it.
22407 * composite.c (get_composition_id): Remove unused local vars,
22408 by using the new macro.
22410 * textprop.c (set_text_properties_1): Change while to do-while,
22411 since the condition is always true at first.
22413 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22414 (interval_deletion_adjustment): Return unsigned value.
22417 * process.c (list_processes_1, create_pty, read_process_output):

22427 (update_syntax_table): Use unsigned instead of int.
22429 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22430 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22431 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22433 * print.c (print_error_message): Avoid int overflow.
22435 * font.c (font_list_entities): Redo for clarity,
22436 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22438 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22439 (font_score): Avoid potential overflow in diff calculation.
22441 * fns.c (substring_both): Remove var that is set but not used.
22442 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22444 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22446 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22447 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22448 can always succeed if overflow has undefined behavior.
22450 * search.c (boyer_moore, wordify): Remove vars set but not used.
22451 (wordify): Omit three unnecessary tests.
22453 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22454 All callers changed. This avoids the need for an unused var.
22456 * casefiddle.c (casify_region): Remove var that is set but not used.
22458 * dired.c (file_name_completion): Remove var that is set but not used.
22460 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22462 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22463 (Finsert_file_contents): Remove unnecessary code checking fd.
22465 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22466 Check for integer overflow on size calculations.
22468 * buffer.c (Fprevious_overlay_change): Remove var that is set
22471 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22472 Remove vars that are set but not used.
22473 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22474 (timer_check_2): Mark vars as initialized.
22476 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22478 * image.c (lookup_image): Remove var that is set but not used.
22479 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22481 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22482 that are set but not used.
22484 * xfns.c (make_invisible_cursor): Don't return garbage
22485 if XCreateBitmapFromData fails (Bug#8410).
22487 * xselect.c (x_get_local_selection, x_handle_property_notify):
22488 Remove vars that are set but not used.
22490 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

22500 (map_tty_color) [!defined MSDOS]: Likewise.
22502 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22504 * coding.c: Remove vars that are set but not used.
22505 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22506 All callers changed.
22507 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22508 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22509 (decode_coding_charset): Remove vars that are set but not used.
22511 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22512 that is set but not used.
22514 * print.c (print_object): Remove var that is set but not used.
22516 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22517 The gnulib version avoids calling malloc in the usual case,
22518 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22519 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22520 * filelock.c (current_lock_owner): Likewise.
22521 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22522 * sysdep.c: Include allocator.h, careadlinkat.h.
22523 (emacs_no_realloc_allocator): New static constant.
22524 (emacs_readlink): New function.
22525 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22526 ../lib/careadlinkat.h.
22528 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22530 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22531 first non-nil return value).

22535 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22536 if not defined (Bug#8403).

22540 * xdisp.c (display_count_lines): Remove parameter `start',
22541 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

22545 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22546 and thereabouts. All callers changed.
22547 (get_per_char_metric): Remove parameter `f', unused since
22548 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22552 do not dereference NULL upon failed strdup
22553 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22554 (ns_get_family): Likewise.
22556 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

22594 (FletX, Flet): Obey lexical binding.
22595 (Fcommandp): Handle closures.
22596 (Feval): New `lexical' arg.
22597 (eval_sub): New function extracted from Feval. Use it almost
22598 everywhere where Feval was used. Look up vars in lexical env.
22600 (Ffunctionp): Move from subr.el.
22601 (Ffuncall): Handle closures.
22602 (apply_lambda): Remove `eval_flags'.
22603 (funcall_lambda): Handle closures and new byte-code-functions.
22604 (Fspecial_variable_p): New function.
22605 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22606 but without exporting it to Lisp.
22608 * doc.c (Fdocumentation, store_function_docstring):
22609 * data.c (Finteractive_form): Handle closures.
22611 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22614 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22616 (exec_byte_code): New function extracted from Fbyte_code to handle new
22617 calling convention for byte-code-functions. Add new byte-codes.
22619 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22621 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22623 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22625 * xdisp.c (redisplay_internal): Fix prototype.
22627 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22629 * xdisp.c (SCROLL_LIMIT): New macro.
22630 (try_scrolling): Use it when setting scroll_limit.
22631 Limit scrolling to 100 screen lines.
22632 (redisplay_window): Even when falling back on "recentering",
22633 position point in the window according to scroll-conservatively,
22634 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22636 (try_scrolling): When point is above the window, allow searching
22637 as far as scroll_max, or one screenful, to compute vertical
22638 distance from PT to the scroll margin position. This prevents
22639 try_scrolling from unnecessarily failing when
22640 scroll-conservatively is set to a value slightly larger than the
22641 window height. Clean up the case of PT below the margin at bottom
22642 of window: scroll_max can no longer be INT_MAX. When aggressive
22643 scrolling is in use, don't let point enter the opposite scroll
22644 margin as result of the scroll.
22645 (syms_of_xdisp) <scroll-conservatively>: Document the
22646 threshold of 100 lines for never-recentering scrolling.
22648 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22650 * dispextern.h (move_it_by_lines):
22651 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22652 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22653 (message_log_check_duplicate): Remove parameters `prev_bol' and
22654 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22655 (redisplay_internal): Remove parameter `preserve_echo_area',
22656 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22658 * indent.c (Fvertical_motion):
22659 * window.c (window_scroll_pixel_based, Frecenter):
22660 Don't pass `need_y_p' to `move_it_by_lines'.
22662 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22664 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22665 steal a few bits to be more compact.
22666 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22667 Remove unneeded casts.
22669 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22671 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22673 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22674 binding" message (bug#7967).
22676 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22678 Fix more problems found by GCC 4.6.0's static checks.
22680 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22681 Remove unused local var.
22683 * editfns.c (Fmessage_box): Remove unused local var.
22685 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22686 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22687 Omit unused local vars.
22688 * window.c (shrink_windows): Omit unused local var.
22689 * menu.c (digest_single_submenu): Omit unused local var.
22690 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22691 Omit unused local var.
22693 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22694 Don't assume string length fits in int.
22695 (keyremap_step, read_key_sequence): Use size_t for sizes.
22696 (read_key_sequence): Don't check last_real_key_start redundantly.
22698 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22699 instead of alloca (Bug#8344).
22701 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22702 (Fbacktrace_frame): Don't assume nframes fits in int.
22704 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22706 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22709 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22711 * cm.c (calccost): Turn while-do into do-while, for clarity.
22713 * keyboard.c (syms_of_keyboard): Use the same style as later
22714 in this function when indexing through an array. This also
22715 works around GCC bug 48267.
22717 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22719 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22721 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22722 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22724 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22725 This avoids undefined behavior on integer overflow, and is a bit
22726 more convenient anyway since it is compared to a size_t variable.
22728 Variadic C functions now count arguments with size_t, not int.
22729 This avoids an unnecessary limitation on 64-bit machines, which
22730 caused (substring ...) to crash on large vectors (Bug#8344).
22731 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22732 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22733 All variadic functions and their callers changed accordingly.
22734 (struct gcpro.nvars): Now size_t, not int. All uses changed.
22735 * data.c (arith_driver, float_arith_driver): Likewise.
22736 * editfns.c (general_insert_function): Likewise.
22737 * eval.c (struct backtrace.nargs, interactive_p)
22738 (internal_condition_case_n, run_hook_with_args, apply_lambda)
22739 (funcall_lambda, mark_backtrace): Likewise.
22740 * fns.c (concat): Likewise.
22741 * frame.c (x_set_frame_parameters): Likewise.
22742 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22743 0 if not found, not -1. All callers changed.
22745 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22746 (stack_copy_size): Now size_t, not int.
22747 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22749 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22751 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22752 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22753 All callers changed.
22755 * lisp.h (multibyte_char_to_unibyte):
22756 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22757 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22758 * character.h (CHAR_TO_BYTE8):
22759 * cmds.c (internal_self_insert):
22760 * editfns.c (general_insert_function):
22761 * keymap.c (push_key_description):
22762 * search.c (Freplace_match):
22763 * xdisp.c (message_dolog, set_message_1): All callers changed.
22765 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
22767 * keyboard.c (safe_run_hook_funcall): New function.
22768 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22769 don't set the hook to nil, but remove the offending function instead.
22770 (Qcommand_hook_internal): Remove, unused.
22771 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22772 Vcommand_hook_internal.
22774 * eval.c (enum run_hooks_condition): Remove.
22775 (funcall_nil, funcall_not): New functions.
22776 (run_hook_with_args): Call each function through a `funcall' argument.
22777 Remove `cond' argument, now redundant.
22778 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
22779 (Frun_hook_with_args_until_failure): Adjust accordingly.
22780 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
22782 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22784 * dispextern.h (string_buffer_position): Remove declaration.
22786 * print.c (strout): Remove parameter `multibyte', unused since
22787 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
22789 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
22790 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22791 All callers changed.
22793 * w32.c (_wsa_errlist): Use braces for struct initializers.
22795 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
22796 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
22797 All callers changed.
22798 (string_buffer_position): Likewise. Also, make static (it's never
22799 used outside xdisp.c).
22800 (cursor_row_p): Remove parameter `w', unused since
22801 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

22803 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
22804 All callers changed.
22806 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22808 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
22810 2011-03-27 Anders Lindgren <andlind@gmail.com>
22812 * nsterm.m (ns_menu_bar_is_hidden): New variable.
22813 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
22814 (ns_update_auto_hide_menu_bar): New functions.
22815 (ns_update_begin): Call ns_update_auto_hide_menu_bar.
22816 (applicationDidBecomeActive): Call ns_update_auto_hide_menu_bar and
22817 ns_constrain_all_frames.

22819 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
22821 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22823 * nsmenu.m (runDialogAt): Remove argument to timer_check.
22825 2011-03-27 Glenn Morris <rgm@gnu.org>
22827 * syssignal.h: Replace RETSIGTYPE with void.
22828 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
22829 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
22830 Replace SIGTYPE with void everywhere.
22831 * s/usg5-4-common.h (SIGTYPE): Remove definition.
22832 * s/template.h (SIGTYPE): Remove commented out definition.
22834 2011-03-26 Eli Zaretskii <eliz@gnu.org>
22836 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
22837 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
22839 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
22841 * w32.c (read_unc_volume): Use parameter `henum', instead of
22842 global variable `wget_enum_handle'.
22844 * keymap.c (describe_vector): Remove parameters `indices' and
22845 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
22846 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
22848 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
22850 * keyboard.c (timer_check): Remove parameter `do_it_now',
22851 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
22852 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
22853 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
22855 * keyboard.c (read_char):
22856 * w32menu.c (w32_menu_display_help):
22857 * xmenu.c (show_help_event, menu_help_callback):
22858 Adjust calls to `show_help_echo'.
22860 * gtkutil.c (xg_maybe_add_timer):
22861 * keyboard.c (readable_events):
22862 * process.c (wait_reading_process_output):
22863 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
22865 * insdel.c (adjust_markers_gap_motion):
22866 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
22867 (gap_left, gap_right): Don't call it.
22869 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
22871 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
22872 incurred during fontification.

22913 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
22915 * w32term.c (x_set_glyph_string_clipping):
22916 Don't pass uninitialized region to CombineRgn.
22918 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
22920 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
22921 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
22922 (Fx_close_connection): Remove unused variable `i'.

22938 (uniscribe_font_driver): Add missing initializers.
22940 2011-03-23 Julien Danjou <julien@danjou.info>
22942 * term.c (Fsuspend_tty, Fresume_tty):
22943 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22944 * window.c (temp_output_buffer_show):
22945 * insdel.c (signal_before_change):
22946 * frame.c (Fhandle_switch_frame):
22947 * fileio.c (Fdo_auto_save):
22948 * emacs.c (Fkill_emacs):
22949 * editfns.c (save_excursion_restore):
22950 * cmds.c (internal_self_insert):
22951 * callint.c (Fcall_interactively):
22952 * buffer.c (Fkill_all_local_variables):
22953 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22955 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22956 unconditionally since it does the check itself.
22958 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22960 Fix more problems found by GCC 4.5.2's static checks.
22962 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22963 the first time through the loop, since we know p0 < p1 then.
22964 This also avoids a gcc -Wstrict-overflow warning.
22966 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22967 leading to a memory leak, possible in functions like
22968 load_charset_map_from_file that can allocate an unbounded number
22969 of objects (Bug#8318).
22971 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22972 that could (at least in theory) be that large.
22974 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22975 This is less likely to overflow, and avoids undefined behavior if
22976 overflow does occur. All callers changed. Use strtoul to scan
22977 for the unsigned long integer.
22978 (pint2hrstr): Simplify and tune code slightly.
22979 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22981 * scroll.c (do_scrolling): Work around GCC bug 48228.
22982 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22984 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22985 This also avoids a warning with gcc -Wstrict-overflow.
22986 (validate_x_resource_name): Simplify count usage.
22987 This also avoids a warning with gcc -Wstrict-overflow.
22989 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22992 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22994 * process.c (Fmake_network_process): Use socklen_t, not int,
22995 where POSIX says socklen_t is required in portable programs.
22996 This fixes a porting bug on hosts like 64-bit HP-UX, where
22997 socklen_t is wider than int (Bug#8277).
22998 (Fmake_network_process, server_accept_connection):
22999 (wait_reading_process_output, read_process_output):
23002 * process.c: Rename or move locals to avoid shadowing.
23003 (list_processes_1, Fmake_network_process):
23004 (read_process_output_error_handler, exec_sentinel_error_handler):
23005 Rename or move locals.
23006 (Fmake_network_process): Define label "retry_connect" only if needed.
23007 (Fnetwork_interface_info): Fix pointer signedness.
23008 (process_send_signal): Add cast to avoid pointer signedness problem.
23009 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
23010 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
23012 Make tparam.h and terminfo.c consistent.
23013 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23014 Include tparam.h instead, since it declares them.
23015 * cm.h (PC): Remove extern decl; tparam.h now does this.
23016 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23017 * terminfo.c: Include tparam.h, to check interfaces.
23018 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
23019 (tparam): Adjust signature to match interface in tparam.h;
23020 this removes some undefined behavior. Check that outstring and len
23021 are zero, which they always are with Emacs.
23022 * tparam.h (PC, BC, UP): New extern decls.
23024 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

23076 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23078 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23079 This should get cleaned up, so that child_setup has the
23080 same signature on all platforms.
23082 * callproc.c (call_process_cleanup): Now static.
23083 (relocate_fd): Rename locals to avoid shadowing.

23214 some of which prompt warnings from gcc -Wbad-function-cast.

23244 (Fmemory_limit): Cast sbrk's returned value to char *.
23246 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

23252 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23253 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23254 to use the following functions instead of these macros.
23255 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23256 EMACS_INT, since callers assume the returned value fits in int.
23257 (upcase1): Likewise, for UPCASE_TABLE.
23258 (uppercasep, lowercasep, upcase): New static inline functions.
23259 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

23269 (regex_compile, re_match_2_internal): Mark locals as initialized.
23270 (RETALLOC_IF): Define only if needed.
23271 (WORDCHAR_P): Likewise. This one is never needed, but is used
23272 only in a comment talking about a compiler bug, so put inside
23273 the #if 0 of that comment.
23274 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23275 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

23302 New macros, so that the caller can use some names other than
23303 gcpro1, gcpro2, etc.
23304 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23306 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23307 argument, for consistency with GCPRO2_VAR, etc: it is now the
23308 prefix of the variable, not the variable itself. All uses
23310 * dired.c (directory_files_internal, file_name_completion):
23311 Rename locals to avoid shadowing.
23313 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23314 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23315 dired.c's scmp function, had undefined behavior.
23316 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23317 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23318 * buffer.h: ... to here, because these macros use current_buffer,
23319 and the new implementation with inline functions needs to have
23320 current_buffer in scope now, rather than later when the macros
23322 (downcase, upcase1): New static inline functions.
23323 (DOWNCASE, UPCASE1): Reimplement using these functions.
23324 This avoids undefined behavior in expressions like
23325 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23326 from race conditions in accessing the global variables
23327 case_temp1 and case_temp2.
23328 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23329 * lisp.h (case_temp1, case_temp2): Remove their decls.
23330 * character.h (ASCII_CHAR_P): Move from here ...
23331 * lisp.h: ... to here, so that the inline functions mentioned
23332 above can use them.
23334 * dired.c (directory_files_internal_unwind): Now static.
23336 * fileio.c (file_name_as_directory, directory_file_name):

23339 (file_name_as_directory): Use const pointers when appropriate.
23340 (Fexpand_file_name): Likewise. In particular, newdir might
23341 point at constant storage, so make it a const pointer.

23343 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23345 (Fset_file_times, Finsert_file_contents, auto_save_error):

23350 to avoid shadowing.
23352 * marker.c (bytepos_to_charpos): Remove; unused.
23354 * lisp.h (verify_bytepos, count_markers): New decls,
23355 so that gcc does not warn that these functions aren't declared.
23357 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23358 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23359 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23360 (copy_text): Remove unused local var.
23362 * filelock.c (within_one_second): Now static.
23363 (lock_file_1): Rename local to avoid shadowing.
23365 * buffer.c (fix_overlays_before): Mark locals as initialized.
23366 (fix_start_end_in_overlays): Likewise. This function should be
23367 simplified by using pointers-to-pointers, but that's a different
23369 (switch_to_buffer_1): Now static.
23370 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23371 (report_overlay_modification): Rename locals to avoid shadowing.

23374 Fix pointer signedness issue.
23375 (sys_subshell): Mark local as volatile if checking for lint,
23376 to suppress a gcc -Wclobbered warning that does not seem to be right.
23377 (MAXPATHLEN): Define only if needed.
23379 * process.c (serial_open, serial_configure): Move decls from here ...
23380 * systty.h: ... to here, so that they can be checked.
23382 * fns.c (get_random, seed_random): Move extern decls from here ...
23383 * lisp.h: ... to here, so that they can be checked.
23385 * sysdep.c (reset_io): Now static.
23386 (wait_for_termination_signal): Remove; unused.
23388 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

23393 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23394 (describe_map_tree):
23395 Rename locals to avoid shadowing.
23397 * keyboard.c: Declare functions static if they are not used elsewhere.
