8 * lread.c (readchar): Don't read from a dead buffer. (Bug#14280)
10 2013-05-07 Jan Djärv <jan.h.d@swipnet.se>
12 * xfns.c: Move misplaced ifndef USE_GTK from previous checkin.
14 2013-05-07 Paul Eggert <eggert@cs.ucla.edu>
16 Static checking by GCC 4.8.0.
17 * xfns.c (x_get_net_workarea, struct MonitorInfo, free_monitors)
18 (x_get_monitor_for_frame, x_make_monitor_attribute_list)
19 (x_get_monitor_attributes_fallback)
20 (x_get_monitor_attributes_xinerama)
21 (x_get_monitor_attributes_xrandr, x_get_monitor_attributes):
22 Define only if USE_GTK.

24 (x_get_monitor_attributes_fallback): Omit unused locals.
25 (x_get_monitor_attributes_xinerama, Fx_display_monitor_attributes_list):
26 Use double, not float, to avoid mixed-mode floating point arithmetic.

43 (x_get_monitor_attributes_xinerama): New functions.
44 (Fx_display_monitor_attributes_list): New primitive.
45 (syms_of_xfns): Defsubr it.
47 * xterm.h (x_display_info): Add Xatom_net_workarea and
48 Xatom_net_current_desktop.
50 * xterm.c (x_term_init): Initialize dpyinfo->Xatom_net_workarea
51 and dpyinfo->Xatom_net_current_desktop.
53 2013-05-06 Eli Zaretskii <eliz@gnu.org>
55 * xdisp.c (pos_visible_p): Use the special code for finding the
56 beginning of a display property or overlay for any "replacing"
57 display property, not just for display strings. This solves
58 incorrect reporting of position by posn-at-point. (Bug#14241)
60 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
62 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
63 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
64 Verify that ElfW (Half) fits in int.
65 (fatal): Use same signature as lisp.h.
66 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
67 configure and build with -DUNEXELF_DEBUG without worrying about
68 other modules that use DEBUG.
69 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
70 possibly-wide integers now uses it instead of plain fprintf.
71 (entry_address): New function, which avoids problems with 32-bit
72 overflow on 64-bit hosts.
73 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
74 (round_up): Don't assume the remainder fits in int.
75 (find_section): Use bool for boolean. Simplify debug code.
76 (unexec): Don't assume file sizes fit in int or size_t.
77 Omit unnecessary trailing newline in 'fatal' format.
78 Use strerror rather than outputting decimal error number.
79 Remove unused code when emacs is not defined;
80 this file relies on Emacs now.
81 Don't assume e_phnum and e_shnum are positive.
83 * regex.c: Fix problems when DEBUG is defined.
84 (extract_number, extract_number_and_incr): Define regardless of
85 whether DEBUG is defined; that's simpler and makes the code less
86 likely to go stale in the normal case when DEBUG is not defined.
87 Return int rather than taking an int * arg. All callers changed.
88 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
89 Remove, replacing with ...
90 (DEBUG_PRINT): New macro. All callers changed.
91 (DEBUG_COMPILES_ARGUMENTS): New macro.

94 Use prototype rather than old-style definition.
95 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
96 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
97 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
98 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
99 Don't assume ptrdiff_t, size_t, and long are the same width as int.
100 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
101 This matters only when DEBUG is defined.
103 2013-05-05 Eli Zaretskii <eliz@gnu.org>
105 * xdisp.c (set_iterator_to_next): Set the
106 ignore_overlay_strings_at_pos_p flag only if we are _really_
107 iterating over an overlay string, as indicated by the
108 current.overlay_string_index member. (Bug#14306)
110 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
112 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
113 to where it is used, to avoid autorelease issues (Bug#14050).
115 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
117 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
118 * fileio.c (syms_of_fileio): Implement this.
119 * filelock.c (create_lock_file): If symbolic links don't work, so
120 we use a regular file as a lock file, do not fsync the lock file;
123 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
125 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.

133 w->contents is a buffer before computing everything else.
134 Use parentheses to disambiguate last part of the condition.
136 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
137 assertion violations. (Bug#14062)
139 2013-05-01 David Reitter <david.reitter@gmail.com>
141 * nsfns.m (ns_tooltip): Initialize.
143 2013-04-28 Eli Zaretskii <eliz@gnu.org>
145 * coding.c (decode_coding_gap): Don't remove the character before
146 a newline unless it's a CR character. (Bug#14287)
148 2013-04-28 Dan Nicolaescu <dann@gnu.org>
150 * dispextern.h (struct face): Move enum face_underline_type

153 2013-04-28 Jan Djärv <jan.h.d@swipnet.se>
155 * nsfns.m (handlePanelKeys): New function.
156 (EmacsOpenPanel:performKeyEquivalent:)
157 (EmacsSavePanel:performKeyEquivalent:): Call handlePanelKeys to handle

160 2013-04-27 Juri Linkov <juri@jurta.org>
162 * callint.c (Fcall_interactively): Call `Qread_number' for
163 interactive code letter `n' instead of using duplicate code.
166 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
168 * systime.h (make_timeval): Declare as 'const'.
170 2013-04-27 Kenichi Handa <handa@gnu.org>
172 * font.c (font_open_entity): Always open a font of manageable
175 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
177 Port better to AIX (Bug#14258).
178 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
181 2013-04-24 Kenichi Handa <handa@gnu.org>
183 * coding.c (decode_coding_iso_2022): When an invalid escape
184 sequence is encountered, reset the invocation and designation
185 status to the safest one.

189 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
190 Without this fix, "make distclean" leaves stamp-h1 behind.
192 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
194 * w32fns.c (w32_fullscreen_rect): New function to compute the
195 window rectangle for the given fullscreen mode.
196 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
197 longer tunes the window size. This keeps the window's edges flush
198 with the screen and allows the taskbar to hide itself in fullboth.
200 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
201 window decorations and uses the entire screen.
203 * w32term.h (w32_fullscreen_rect) Add prototype.
204 (struct w32_output): Replace normal_width, normal_height,
205 normal_top, and normal_left members with a single normal_placement
207 (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP):
209 (FRAME_NORMAL_PLACEMENT): New macro.
211 2013-04-16 Juanma Barranquero <lekktu@gmail.com>
213 * minibuf.c (Ftest_completion): Silence compiler warning.
215 2013-04-15 Eli Zaretskii <eliz@gnu.org>
217 * w32fns.c (w32_wnd_proc): Add more assertions to investigate
220 * frame.h (WINDOW_FRAME): Protect macro and its argument with
223 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
224 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
225 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
226 parentheses where appropriate.
228 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
230 * keyboard.c (timer_start_idle): Remove no-longer-used local.
232 2013-04-14 Eli Zaretskii <eliz@gnu.org>
234 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
235 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
236 Mention in the doc string that setting these variables takes
237 effect only after a call to set-window-buffer. (Bug#14200)
239 2013-04-13 Eli Zaretskii <eliz@gnu.org>
241 * indent.c (Fvertical_motion): Don't consider display strings on
242 overlay strings as display strings on the buffer position we
243 started from. This prevents vertical cursor motion from jumping
244 more than one line when there's an overlay string with a display
245 property at end of line.
246 Reported by Karl Chen <Karl.Chen@quarl.org> in
247 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.
249 2013-04-12 Stefan Monnier <monnier@iro.umontreal.ca>
251 * window.c (select_window): `record_buffer' even if window is
252 already selected (bug#14191).
254 2013-04-11 Eli Zaretskii <eliz@gnu.org>
256 * window.c (Fwindow_end): Test more flags, including the buffer's
257 last_overlay_modified flag, to determine whether the window's
258 display is really up-to-date. Prevents the function from
259 returning a stale value. (Bug#14170)
260 (Fwindow_line_height): Fix the test for up-to-date-ness of the
263 2013-04-10 Eli Zaretskii <eliz@gnu.org>
265 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
266 garbaged only if it is not already the top frame on its TTY.
267 This prevents flickering due to constant redrawing of TTY frames when
268 there are GUI frames open in the same session. (Bug#13864)
270 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
272 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
273 of marking the idle timers directly.
275 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
277 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
280 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>

297 2013-03-31 Jan Djärv <jan.h.d@swipnet.se>
299 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
302 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
304 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
305 This bug was introduced by my 2013-02-25 change that simplified
306 data_start configuration. Without this change, on GNU/Linux
307 an Emacs configured with --enable-profiling fails immediately
308 due to a profiler signal.
309 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
310 with these flags. On platforms where special flags are needed
311 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
312 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
313 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
315 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>
317 Get rid of some platform-specific functions examining window
318 system and its capabilities. This is a partial rework of the
320 * lisp.h (have_menus_p): Remove prototype. This function is
321 replaced with platform-independent window_system_available.
322 (check_window_system): Move to...
323 * frame.h (decode_window_system_frame, window_system_available):
324 ...here, add new prototypes.

328 * xterm.h (x_in_use): Remove declaration.
330 * w32term.h (check_x_frame):
331 * nsterm.h (check_x_frame): Remove prototypes. This function
332 is replaced with platform-independent decode_window_system_frame.
333 * msdos.c (have_menus_p): Remove.
334 * nsfns.m (check_window_system, have_menus_p, check_ns_frame):
335 Remove platform-specific functions. Use check_window_system,
336 decode_window_system_frame and check_ns_display_info where
337 appropriate. Minor style and comment tweaks.

352 changed. Check EOL format. Do not call adjust_coding_eol_type
354 (check_utf_8): New function.
355 (adjust_coding_eol_type): Do nothing if already adjusted.
356 (detect_coding): Compare the return value of check_ascii with
357 coding->src_bytes. Call adjust_coding_eol_type if necessary.
358 (decode_coding_gap): Optimize for valid UTF-8.
360 2013-03-21 Kenichi Handa <handa@gnu.org>
362 * coding.c (syms_of_coding): Cancel previous change.
364 * insdel.c (insert_from_gap): Fix previous change.
366 2013-04-05 Dmitry Antipov <dmantipov@yandex.ru>
368 Consistently use platform-specific function to detect window system.
369 * lisp.h (check_window_system): New prototype. This function is

385 2013-04-02 Paul Eggert <eggert@cs.ucla.edu>
387 Prefer < to > in range checks such as 0 <= i && i < N.
388 This makes it easier to visualize quantities on a number line.
389 This patch doesn't apply to all such range checks,
390 only to the range checks affected by the 2013-03-24 change.
391 This patch reverts most of the 2013-03-24 change.

415 * xsmfns.c (smc_save_yourself_CB):
416 Prefer < to > for range checks.
417 * dispnew.c (sit_for): Don't mishandle NaNs.
418 This fixes a bug introduced in the 2013-03-24 change.
419 * editfns.c (decode_time_components): Don't hoist comparison.
420 This fixes another bug introduced in the 2013-03-24 change.
422 2013-03-31 Dmitry Antipov <dmantipov@yandex.ru>
424 * frame.h (struct frame): Drop scroll_bottom_vpos
425 member becaue all real users are dead long ago.

431 * nsmenu.m (showAtX:Y:for:): setLevel to
432 NSPopUpMenuWindowLevel (Bug#13998).
434 2013-03-30 Jan Djärv <jan.h.d@swipnet.se>
436 * nsterm.h (ns_get_pending_menu_title, ns_check_menu_open)
437 (ns_check_pending_open_menu): Declare.
439 * nsmenu.m (ns_update_menubar): Correct NSTRACE.
440 (x_activate_menubar): Update the menu with title that matches

474 2013-03-28 Dmitry Antipov <dmantipov@yandex.ru>
476 * window.h (struct window): Replace hchild, vchild and buffer slots
477 with the only contents slot. This is possible because each valid
478 window may have either the child window (in vertical or horizontal
479 combination) or buffer to display (for the leaf window). Using that,
480 a lof of operations to traverse and/or change window hierarchies may
481 be simplified. New member horizontal is used to distinguish between
482 horizontal and vertical combinations of internal windows.

707 'fullscreen' parameter. Always record previous width and height
708 of the frame, except when switching out of maximized modes, so
709 that they could be restored correctly, instead of resetting to the
710 default frame dimensions. Send SC_RESTORE command to the frame,
711 unless we are going to send SC_MAXIMIZE, to restore the frame

858 * coding.h (struct coding_system): New member eol_seen.
860 * coding.c (detect_ascii): New function.
861 (detect_coding): Set coding->head_ascii and coding->eol_seen only
862 when the source bytes are actually scanned. On detecting for
863 coding_category_utf_8_auto, call detect_ascii instead of scanning
864 source bytes directly.
865 (produce_chars): Call insert_from_gap with the new arg 0.
866 (encode_coding): Likewise.
867 (decode_coding_gap): Control ASCII optimization by the variable

900 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
901 too so that these builds can use Cygwin's file conversion
902 functions. (We've been building and linking cygw32.o all along
903 and just not using it.)
905 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

918 * w32term.c (w32_read_socket): If the Emacs frame is being
919 activated, call w32fullscreen_hook, to make sure the new frame
920 dimensions are in effect. (Bug#13937)
922 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
924 * xdisp.c (init_iterator): Simplify because both character and byte
925 positions are either specified or -1. Add eassert. Adjust comment.
926 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
927 character and byte positions can be obtained from marker.

947 Include <sys/param.h> unconditionally, as that works elsewhere and
948 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
949 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
952 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>
954 * insdel.c (adjust_after_replace): Use bool for boolean.
956 2013-03-11 Stefan Monnier <monnier@iro.umontreal.ca>

1036 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1037 from Elisp via unread-command-events.
1039 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1040 functions to mean "no change".

1050 (search_regs_saved, Fregexp_quote):
1051 Use bool for boolean.
1052 * region-cache.c (region_cache_forward, region_cache_backward):
1053 Fix comments to match code: these functions return int, not boolean.
1055 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1057 * search.c (find_newline): Accept start and end byte positions
1058 as arguments and allow -1 if not known.

1093 to match other functions accepting character and byte positions.
1095 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

1097 when you need just to move to the previous buffer position.
1098 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1100 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1175 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1176 * sysdep.c (list_system_processes)
1177 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1178 Make it a stub in this case; otherwise the build might fail,
1179 and this code hasn't been tested on such hosts anyway.
1180 Problem reported by Nelson H. F. Beebe in
1181 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1182 and analyzed by Jérémie Courrèges-Anglas in
1183 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1185 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1187 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1188 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1189 (get_visually_first_element, move_it_vertically_backward): Ajust users.

1193 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1195 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1196 * filelock.c: Include <c-ctype.h>.
1197 (MAX_LFINFO): New top-level constant.
1198 (lock_info_type): Remove members pid, boot_time. Add members at,
1199 dot, colon. Change user member to be the entire buffer, not a
1200 pointer. This allows us to handle the case where a foreign
1201 pid or boot time exceeds the local range. All uses changed.
1202 (LINKS_MIGHT_NOT_WORK): New constant.
1203 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1204 (defined_WINDOWSNT): Remove.
1205 (MAKE_LOCK_NAME, file_in_lock_file_name):
1206 Always use .#FILE (not .#-FILE) for the file lock,
1207 even if it is a regular file.
1208 (rename_lock_file): New function.
1209 (create_lock_file): Use it.
1210 (create_lock_file, read_lock_data):
1211 Prefer a symbolic link for the lock file, falling back on a
1212 regular file if symlinks don't work. Do not try to create
1213 symlinks on MS-Windows, due to security hassles. Stick with
1214 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1215 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1216 host may be using a Windowsish file system, and cannot use
1217 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1218 doesn't work. Don't fail merely because of a symlink-contents
1219 length limit in the current file system; fall back on regular
1220 files. Increase the symlink contents length limit to 8 KiB, this
1221 should be big enough for any real use and doesn't crunch the
1223 (create_lock_file, lock_file_1, read_lock_data):
1224 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1225 (lock_file_1): Return error number, not bool. All callers changed.
1226 (ELOOP): New macro, if not already defined.
1227 (read_lock_data): Return size of lock file contents, not Lisp object.
1228 All callers changed. Handle a race condition if some other process
1229 replaces a regular-file lock with a symlink lock or vice versa,
1230 while we're trying to read the lock.
1231 (current_lock_owner): Parse contents more carefully, to help avoid
1232 confusing a regular-file lock with some other application's use
1233 of the file. Check for lock file contents being too long, or
1234 not parsing correctly.
1235 (current_lock_owner, lock_file):
1236 Allow foreign pid and boot times that exceed the local range.
1237 (current_lock_owner, lock_if_free, lock_file):
1238 Simplify allocation of lock file contents.
1239 * w32.c (sys_rename_replace): New function, containing most of
1240 the contents of the old sys_rename.
1241 (sys_rename): Use it.
1242 (fchmod): New dummy function.
1243 * w32.h (sys_rename_replace, fchmod): New decls.
1245 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1247 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1248 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1249 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1250 <dmantipov@yandex.ru>.
1252 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1254 * composite.c (get_composition_id, fill_gstring_header):
1255 Use make_uninit_vector where appropriate.
1256 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1257 * xselect.c (clean_local_selection_data): Likewise.
1259 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1261 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1262 * image.c (imagemagick_load_image): Calculate height and width
1263 after flattening the image, not before.
1265 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1267 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1268 * ftfont.c (ftfont_shape_by_flt): Likewise.
1269 * w32uniscribe.c (uniscribe_shape): Likewise.
1271 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1273 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1274 The old approach, which fell back on DIR/.#FILE.0 through
1275 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1276 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1277 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1278 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1279 because the locking mechanism was never reliable in that case).
1280 This patch fixes this and other bugs discovered by a code
1281 inspection that was prompted by
1282 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1283 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1284 to avoid interoperability problems between the MS-Windows and
1285 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1286 instances of Emacs now ignore each others' locks.
1287 * filelock.c (defined_WINDOWSNT): New constant.
1288 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1289 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1290 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1291 regular files on MS-Windows hosts.
1292 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1293 Use SAFE_ALLOCA to avoid problems with long file names.
1294 (MAX_LFINFO): Now a local constant, not a global macro.
1295 (IS_LOCK_FILE): Remove.
1296 (lock_file_1): Don't inspect errno if symlink call succeeds;
1297 that's not portable.
1298 (lock_file): Document that this function can return if lock
1300 (lock_file): Don't access freed storage.
1302 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

1306 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1308 * textprop.c: Use bool for booleans.
1309 (validate_interval_range, Fadd_text_properties)
1310 (Fremove_text_properties): Prefer bool to int when either works.
1312 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1314 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1315 If the interval tree changes as a side effect of calling
1316 modify_region, re-do processing starting from the call to
1317 validate_interval_range. (Bug#13743)
1319 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1321 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1324 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1326 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1327 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1328 access to the lock file until it is written and closed.
1331 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1333 * callint.c (Qcall_interactively):
1334 * macros.c (Qexecute_kbd_macro):

1339 * window.c (Frecenter): Tiny docstring enhancement.
1341 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1343 Minor textprop integer cleanup.
1344 * intervals.h, textprop.c (add_text_properties_from_list):
1345 Return void, not int, since nobody uses the return value.
1346 * textprop.c (validate_plist, add_properties, remove_properties)
1347 (Fadd_text_properties):
1348 Don't assume list length fits in int.
1349 (interval_has_all_properties, interval_has_some_properties)
1350 (interval_has_some_properties_list, add_properties, remove_properties)

1352 (Fremove_list_of_text_properties, text_property_stickiness):
1353 Use bool for booleans.

1355 (Fremove_list_of_text_properties):
1356 Reindent do-while as per GNU style.
1358 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1360 Implement CLASH_DETECTION for MS-Windows.
1362 * filelock.c [WINDOWSNT]: Include w32.h.
1363 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1364 function of that name. Up-case the macro arguments.
1365 (IS_LOCK_FILE): New macro.
1366 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1367 (create_lock_file): New function, with body extracted from
1369 [WINDOWSNT]: Implement lock files by writing a regular file with
1370 the lock information as its contents.
1371 (read_lock_data): New function, on Posix platforms just calls
1373 [WINDOWSNT]: Read the lock info from the file.
1374 (current_lock_owner): Call read_lock_data instead of calling
1375 emacs_readlinkat directly.
1376 (lock_file) [WINDOWSNT]: Run the file name through
1379 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1380 just check if the process by that PID exists.
1382 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1383 also present, as doing so will fail to error out if the file
1386 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1388 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1389 (Fremove_list_of_text_properties): Skip all of the intervals in
1390 the region between START and END that already have resp. don't
1391 have the requested properties, not just the first one.
1392 Add assertions that the loop afterwards always modifies the
1393 properties. (Bug#13743)
1395 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1397 * callint.c (Fcall_interactively): Use the right lexical environment

1401 2013-02-25 Paul Eggert <eggert@cs.ucla.edu>
1403 Simplify data_start configuration (Bug#13783).
1404 This is a followon simplification to the fix for Bug#13650.

1423 * vm-limit.c: Move most of mem-limits.h's contents here.
1424 (data_start): New decl. It's OK if this is approximate,
1425 so simplify-away some unnecessary exactness.
1426 (POINTER): Remove; all uses removed.
1427 (data_space_start): Now char *, to avoid casts.
1428 (exceeds_lisp_ptr): New function, replacing the old
1429 EXCEEDS_LISP_PTR macro. All uses changed.

1451 * ralloc.c (SIZE, POINTER, NIL):
1452 * vm-limit.c (POINTER):
1453 Remove, replacing all uses with C89 equivalents. These old
1454 symbols were present only for porting to pre-C89 platforms.
1456 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1458 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.

1474 2013-02-19 Daniel Colascione <dancol@dancol.org>
1476 * sheap.c (report_sheap_usage): Use message, not message1, so
1477 that we don't try to create a buffer while we're in the middle
1478 of dumping Emacs. Explain why.
1480 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>

1577 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1579 Fix AIX port (Bug#13650).
1580 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1581 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1582 was #undeffed earlier, so it cannot be used as a macro here.
1583 Use the constant and not the macro.
1585 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1587 * w32proc.c (new_child): If no vacant slots are found in
1588 child_procs[], make another pass looking for slots whose process
1589 has exited or died. (Bug#13546)
1591 * w32.c (sys_pipe): When failing due to file descriptors above
1592 MAXDESC, set errno to EMFILE.
1593 (_sys_read_ahead): Update cp->status when failing to read serial
1594 communications input, so that the status doesn't stay at
1595 STATUS_READ_IN_PROGRESS. (Bug#13546)
1597 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1599 * gtkutil.c (tb_size_cb): New function.

1609 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1611 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1619 2013-02-13 Glenn Morris <rgm@gnu.org>
1621 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1623 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1625 Improve AIX port some more (Bug#13650).
1626 With this, it should be as good as it was in 23.3, though it's
1627 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1628 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1629 * unexaix.c (start_of_text): Remove.
1630 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1631 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1632 (orig_load_scnptr, orig_data_scnptr):
1633 Now off_t, not long, since they are file offsets.
1634 (make_hdr): Use _data, not start_of_data ().
1635 This is the key part of the fix.
1636 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1637 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1639 * pre-crt0.c (data_start): Initialize to 1.
1640 This ports to compilers that optimize the external declaration
1641 'int x = 0;' as if it were 'int x;' to shrink the executable.
1643 Improve AIX port (Bug#13650).
1644 This doesn't fix the bug, but it makes progress: Emacs builds now.
1645 * unexaix.c: Include inttypes.h, stdarg.h.
1646 (report_error, report_error_1): Mark as _Noreturn.
1647 (report_error): Don't report the wrong errno.
1648 (report_error_1): Now varargs. All callers changed.
1649 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1650 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1651 (write_ptr): Use %p to print address rather than %lx and a cast
1652 to unsigned long. Grow buffer a bit, to be safer.
1654 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1656 * bidi.c (bidi_resolve_neutral): After finding the next
1657 non-neutral character, accept NEUTRAL_ON type as well, because
1658 directional control characters, such as LRE and RLE, have their
1659 type converted to that by bidi_resolve_weak. This avoids aborts
1660 when LRE/RLE follows a run of neutrals.
1661 (bidi_move_to_visually_next): Assert that return value of
1662 bidi_peek_at_next_level is non-negative. Negative values will
1665 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1667 Minor getenv-related fixes.
1668 * callproc.c (Fcall_process_region) [!DOS_NT]:
1669 Avoid unnecessary duplicate call to getenv.
1670 * callproc.c (init_callproc):
1671 * dispnew.c (init_display):
1672 * sysdep.c (sys_subshell):
1673 Omit unnecessary cast of getenv or egetenv.
1675 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1677 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1678 Update dependencies.
1680 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1682 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1684 (display_line): Set w->region_showing to the value of
1685 it->region_beg_charpos, not to -1. This fixes redisplay
1686 optimization when cursor is moved up after M->. (Bug#13623)
1688 (try_scrolling): Scroll text up more if point is too close to ZV
1689 and inside the scroll margin. This makes sure point is moved
1690 outside the scroll margin in these cases.
1692 * window.h (struct window): region_showing can no longer be
1695 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1697 Tune by using memchr and memrchr.
1698 * doc.c (Fsnarf_documentation):
1699 * fileio.c (Fsubstitute_in_file_name):
1700 * search.c (find_newline, scan_newline):
1701 * xdisp.c (pos_visible_p, display_count_lines):
1702 Use memchr and memrchr rather than scanning byte-by-byte.
1703 * search.c (find_newline): Rename from scan_buffer.
1704 Omit first arg TARGET, as it's always '\n'. All callers changed.
1706 Clean up read_key_sequence a tiny bit more.
1707 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1708 (read_key_sequence): Remove unused locals.
1710 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1712 Clean up read_key_sequence a bit; reread active keymaps after first event.
1713 * keyboard.c (read_char, read_char_x_menu_prompt)
1714 (read_char_minibuf_menu_prompt):
1715 Replace nmaps+maps with a single `map' arg.
1716 (follow_key): Operate on a single map.
1717 (active_maps): New function.
1718 (test_undefined): Also return true for nil bindings.
1719 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1720 a single (composed) keymap. Remember `first_event' to choose the right
1721 set of active keymaps. Recompute the set of keymaps after receiving
1722 the first event. Remove GOBBLE_FIRST_EVENT.
1723 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1724 * keyboard.h (read_char): Update declaration.
1725 * lread.c (read_filtered_event): Adjust call to read_char.
1727 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1729 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1730 Don't use the limitation on backwards movement when lines are truncated
1731 in the window. (Bug#13675)
1733 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1735 * marker.c (set_marker_internal): If desired position is passed
1736 as a marker, avoid call to buf_charpos_to_bytepos.
1737 * window.c (Fset_window_point): Omit redundant type checking.
1738 (Fset_window_start): Likewise. Format comment.
1739 (window_scroll_pixel_based): Use set_marker_restricted_both
1740 with character and byte positions obtained from an iterator.
1741 (Fset_window_configuration): Use set_marker_restricted_both.
1742 * xdisp.c (message_dolog): Likewise.
1744 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1746 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1747 When text lines are longer than window's screen lines, don't move back
1748 too far. This speeds up some redisplay operations. (Bug#13675)
1750 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1752 * syntax.c (scan_sexps_forward): Fix byte position calculation
1753 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1755 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1757 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1758 that was not needed.
1760 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1762 Minor hashing refactoring.
1763 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1764 (sxhash_float): Return EMACS_UINT, for consistency with the other
1766 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1767 non-static inline function and therefore can't use static vars.
1768 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1769 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1770 with the other hash functions.
1772 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1774 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1775 XXXXXX part of the temporary file pattern is not downcased even
1776 when w32-downcase-file-names is non-nil. (Bug#13661)
1778 * xdisp.c (decode_mode_spec): Remove handling of %t.

1864 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1866 * xdisp.c (window_buffer_changed): region_showing can be negative,
1867 which still means region is being displayed.
1868 (redisplay_internal): Resurrect code that forced redisplay of the
1869 whole window when showing region and the mark has changed.
1870 Record the new mark position to allow redisplay optimizations.
1871 (display_line): If it->region_beg_charpos is non-zero, set the
1872 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1874 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1875 not bitfield of 1 bit.
1877 2013-02-03 Daniel Colascione <dancol@dancol.org>
1879 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1880 daemon mode works on cygw32 when Emacs is installed and not just
1883 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1885 Avoid file time stamp bug on MS-Windows (Bug#13149).
1886 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1887 as FAT32 doesn't update time stamps when truncating them.
1888 Also, check that a file time stamp is not a multiple of 100 ns;
1889 this should catch all instances of the problem on MS-Windows,
1890 as its native file system resolution is 100 ns or worse, and
1891 checking for a non-multiple of 100 ns should impose only a small
1892 overhead on systems with ns resolution.
1894 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1896 Avoid encoding file names on MS-Windows when they need to be run
1897 through dostounix_filename.
1898 * w32.c (normalize_filename): Accept an additional argument
1899 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1900 downcase it even if w32-downcase-file-names is non-nil.
1901 (dostounix_filename): Accept an additional argument MULTIBYTE and
1902 pass it to normalize_filename.
1903 (emacs_root_dir): Adjust.
1905 * msdos.h (dostounix_filename): Adjust prototype.
1907 * w32.h (dostounix_filename): Adjust prototype.
1909 * msdos.c (dostounix_filename): Accept an additional argument and
1911 (init_environment): Adjust callers of dostounix_filename.
1913 * fileio.c (Ffile_name_directory, file_name_as_directory)
1914 (directory_file_name, Fexpand_file_name)
1915 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1917 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1919 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1920 variables, as egetenv is case-insensitive for DOS_NT.
1922 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1923 with an encoded file name.
1925 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1926 Adjust calls to dostounix_filename.
1928 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1930 * unexw32.c (unexec): Adjust call to dostounix_filename.
1932 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1934 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1937 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1940 * callproc.c (Fcall_process): Make sure program name in PATH and
1941 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1942 is passed to exec/spawnve, which fails unless the file-name
1945 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1946 even if w32-quote-process-args is nil.
1948 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1950 Fix timestamp bug when write-region appends nothing (Bug#13149).
1951 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1952 the file's time stamp doesn't change if Emacs happens to write nothing
1953 to the file, and on a buggy file system this could cause Emacs to
1954 incorrectly infer that the file system doesn't have the bug.
1955 Avoid this problem by inhibiting the inference in this case.
1957 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1959 * window.h (struct window): Convert base_line_number, base_line_pos
1960 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1961 Convert region_showing member from Lisp_Object to bitfield.
1962 Remove sequence_number member. Adjust comments.
1963 * window.c (sequence_number): Remove.
1964 (make_window): Initialize column_number_displayed.
1965 * print.c (print_object): Follow the printed representation of
1966 frames and print window pointer to distinguish between windows.
1967 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1968 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1969 (wset_column_number_displayed, wset_region_showing): Remove.
1970 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1971 (try_scrolling, try_cursor_movement, redisplay_window)
1972 (try_window_reusing_current_matrix, try_window_id, display_line)
1973 (display_mode_lines, decode_mode_spec): Adjust users.
1974 * .gdbinit (pwinx): Do not print sequence_number.
1976 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1978 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1979 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1980 * dired.c: Include <fcntl.h>.
1981 (open_directory): New function, which uses open and fdopendir
1982 rather than opendir. DOS_NT platforms still use opendir, though.
1983 (directory_files_internal, file_name_completion): Use it.
1984 (file_attributes): New function, with most of the old Ffile_attributes.
1985 (directory_files_internal, Ffile_attributes): Use it.
1986 (file_attributes, file_name_completion_stat): First arg is now fd,
1987 not dir name. All uses changed. Use fstatat rather than lstat +
1989 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1990 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1991 (emacs_readlinkat): New function, with much of the old
1992 Ffile_symlink_p, but with an fd argument for speed.
1993 It uses readlinkat rather than careadlinkatcwd, so that it
1994 need not assume the working directory.
1995 (Ffile_symlink_p): Use it.
1996 * filelock.c (current_lock_owner): Use emacs_readlinkat
1997 rather than emacs_readlink.
1998 * lisp.h (emacs_readlinkat): New decl.
1999 (READLINK_BUFSIZE, emacs_readlink): Remove.
2000 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
2001 (emacs_norealloc_allocator, emacs_readlink): Remove.
2002 This stuff is moved to fileio.c.
2003 * w32.c (fstatat, readlinkat): New functions.
2004 (careadlinkat): Don't check that fd == AT_FDCWD.
2005 (careadlinkatcwd): Remove; no longer needed.
2007 2013-01-31 Glenn Morris <rgm@gnu.org>
2009 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2010 (Fwrite_region): Update for new choose_write_coding_system args.
2011 Move the last piece of choose_write_coding_system here. (Bug#13522)
2012 (syms_of_fileio): Add choose-write-coding-system.
2014 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2016 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2017 (sys_close): Zero out the flags for the file descriptor before
2018 closing it. (Bug#13546)
2020 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2021 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2022 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2025 * w32.c (w32_get_long_filename, init_environment, readlink):
2026 Support file names encoded in DBCS codepages.
2027 (readlink): Use the current file-name-coding-system, not the ANSI
2028 codepage, to decode and handle targets of symlinks.
2030 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2032 * w32.c (opendir): Now accepts a 'const char *'.
2034 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2036 Remove obsolete redisplay code. See the discussion at
2037 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2038 * dispnew.c (preemption_period, preemption_next_check): Remove.
2039 (Vredisplay_preemption_period): Likewise.
2040 (update_frame, update_single_window, update_window, update_frame_1):
2041 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2042 used, following the 2012-06-22 change.
2044 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2046 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2048 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2050 * font.c (num_fonts): Remove the leftover from old
2051 debugging code. Adjust comment style here and there.
2052 * insdel.c (insert_1): Remove.
2053 * lisp.h (insert_1): Remove prototype.
2054 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2056 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2058 * w32.c (max_filename_mbslen): New function.
2059 (normalize_filename, readdir): Use it to detect locales where ANSI
2060 encoding of file names uses a double-byte character set (DBCS).
2061 If a DBCS encoding is used, advance by characters using
2062 CharNextExA, instead of incrementing a 'char *' pointer.
2063 Use _mbslwr instead of _strlwr. (Bug#13515)
2065 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2066 request of memory reservation to 1.7GB. (Bug#13065)
2068 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2070 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2071 at check_extra_latin label. (Bug#13505)
2073 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2075 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2076 Avoid redundant calls to strlen.
2078 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2080 Drop async_visible and async_iconified fields of struct frame.
2081 This is possible because async input is gone; for details, see
2082 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2083 * frame.h (struct frame): Remove async_visible and async_iconified
2084 members, convert garbaged to unsigned bitfield. Adjust comments.
2085 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2086 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2087 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2088 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2089 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2091 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2092 properly. Likewise for obscured.
2094 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2097 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2099 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2101 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2102 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2104 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2106 * xdisp.c (message2, message2_nolog): Remove functions.
2107 (message3, message3_nolog): Extract nbytes and multibyteness directly
2108 from the string. Change all callers.
2109 (message3_nolog): Don't set message_enable_multibyte since set_message
2110 will reset it anyway.
2111 (message1, message1_nolog): Use message3.
2112 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2113 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2114 (set_message): Drop all but the second arg, which has to be a string.
2115 (set_message_1): Simplify now that we know that a1 is NULL and the
2116 second arg is a string.
2117 * frame.h (struct frame): Remove `message_buf' field.
2118 Use glyphs_initialized_p instead.
2119 (FRAME_MESSAGE_BUF): Remove macro.
2120 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2121 * lisp.h (message2, message2_nolog): Remove declarations.
2122 (message3, message3_nolog): Update declarations.
2123 * keyboard.c (read_char_minibuf_menu_text)
2124 (read_char_minibuf_menu_width): Remove vars.
2125 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2126 to correctly handle multibyte strings.
2127 * frame.c (delete_frame): Don't free message_buf any more.
2128 * editfns.c (message_text, message_length): Remove vars.
2129 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2130 * fileio.c (auto_save_error): Use message3 instead of message2.
2131 * dispnew.c (adjust_frame_message_buffer): Remove function.
2133 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2135 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2136 real estate used for the tool bar and the menu bar.
2138 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2140 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2141 hidden buffer is prepared to modification (Bug#13164).
2143 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2145 * window.h (struct window): Change window_end_valid member from
2146 Lisp_Object to a bitfield. Adjust comments.
2147 (wset_window_end_valid): Remove.
2148 * window.c (adjust_window_count): Clear window_end_valid.
2149 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2150 (Fwindow_line_height, set_window_buffer, Frecenter)
2151 (Fsplit_window_internal, Fdelete_other_windows_internal)
2152 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2153 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2154 * xdisp.c (check_window_end, reconsider_clip_changes)
2155 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2156 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2157 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2159 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2161 * xdisp.c (mark_window_display_accurate): Simplify the loop
2162 assuming that the only one of vchild, hchild or buffer window
2163 slots is non-nil. Call mark_window_display_accurate_1 for
2164 the leaf windows only.
2165 (mark_window_display_accurate_1): Always assume leaf window.
2168 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2170 * emacs.c (Qkill_emacs_hook): Now static.
2172 * fileio.c (Finsert_file_contents): Simplify.
2173 Remove unnecessary assignments and tests.
2175 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2177 * w32.c (acl_set_file): Don't test for errors unless
2178 set_file_security returns FALSE. Avoids spurious errors when
2181 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2183 * fileio.c (Finsert_file_contents): Revert code introduced at
2184 2013-01-18 in favor of the simpler and generally better fix.
2185 Save stack space by removing 'buffer' and reusing 'read_buf'
2188 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2190 * lisp.h (eabs): Define unconditionally (Bug#13419).
2191 The old "#if !defined (eabs)" was an unnecessary revenant of back
2192 when this macro was called "abs". Document 'eabs' better.
2194 2013-01-19 Glenn Morris <rgm@gnu.org>
2196 * fns.c (Frandom): Doc fix.
2198 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2200 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2201 segfault when there are lots of overlays.
2203 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2204 when there are lots of overlays.
2205 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2206 for the details and a way to reproduce.
2208 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2210 * fileio.c: Use O_APPEND to append.
2211 This corresponds better to the natural interpretation of "append",
2212 and avoids the need to open the output file twice, or to invoke
2213 lseek when APPEND is neither nil nor a number.
2214 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2215 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2216 file possibly twice, and lseeking to its end; this avoids the
2217 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2218 at the same time: the combination is never needed and apparently
2219 it doesn't work with DOS_NT.
2221 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2222 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2224 Allow floating-point file offsets.
2225 Problem reported by Vitalie Spinu in
2226 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2227 * fileio.c (emacs_lseek): Remove.
2228 (file_offset): New function.
2229 (Finsert_file_contents, Fwrite_region): Use it.
2231 2013-01-19 Chong Yidong <cyd@gnu.org>
2233 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2234 aborting on Fsignal (Bug#13289).
2236 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2238 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2239 set_file_security as failure due to insufficient privileges.
2240 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2241 (fstat): Return owner and group like 'stat' and 'lstat' do.
2243 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2245 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2246 The bug was observed on Ubuntu operating inside a virtual machine,
2247 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2248 The workaround introduces a race condition on non-buggy hosts,
2249 but it's an unlikely race and anyway there's a nearly identical
2250 nearby race that can't be fixed.
2251 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2253 (Fwrite_region): Test for file system time stamp bug.
2254 (init_fileio): New function.
2255 * lisp.h (init_fileio): Declare it.
2256 * emacs.c (main): Call it.
2258 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2259 and make it more consistent with other stat-failure diagnostics.
2261 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2263 Fix crash when inserting data from non-regular files.
2264 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2265 for the error description produced by valgrind.
2266 * fileio.c (read_non_regular): Rename to read_contents.
2267 Free Lisp_Save_Value object used to pass parameters.
2268 (read_non_regular_quit): Rename to read_contents_quit.
2269 (Finsert_file_contents): Redesign internal file reading loop to adjust
2270 gap and end positions after each read and so help make_gap to work
2271 properly. Do not signal an I/O error too early and so do not leave
2272 not yet decoded characters in a buffer, which was the reason of
2273 redisplay crash. Use list2 to build return value. Adjust comments.
2275 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2277 Close a race when statting and reading files (Bug#13149).
2278 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2279 This avoids a race if the file is renamed between stat and open.
2280 This race is not the problem originally noted in Bug#13149;
2281 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2283 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
2285 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
2286 objects, related functions and macros.
2287 (make_save_value): Adjust prototype.
2288 (make_save_pointer): New prototype.
2289 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
2290 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2291 * alloc.c (format_save_value): Rename to make_save_value.
2292 (make_save_pointer): New function.
2293 (record_xmalloc): Use make_save_pointer.
2294 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2295 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2296 Change users of make_save_value to make_save_pointer.
2297 Likewise for format_save_value and make_save_value.
2299 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
2301 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
2302 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
2303 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
2306 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
2308 * alloc.c (free_save_value): Now static.
2310 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2312 * keymap.c (map_keymap_internal): Use format_save_value.
2313 (map_keymap_char_table_item): Adjust accordingly.
2314 * fileio.c (non_regular_fd, non_regular_inserted)
2315 (non_regular_nbytes): Remove.
2316 (Finsert_file_contents): Convert trytry to ptrdiff_t.

2381 Lisp_Save_Value and so avoid xmalloc.
2382 (save_excursion_restore): Adjust to match new layout. Use free_misc
2383 because we do not allocate extra memory any more. Add eassert.
2384 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2385 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

2399 Fix SIGDANGER handlers, for AIX (Bug#13408).
2400 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

2469 * term.c (init_tty): Use them instead of rolling our own code.
2470 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2471 switches from 'signal' to 'pthread_sigmask', which is safer in
2472 multithreaded applications.
2473 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2474 which has already arranged for that.
2475 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2476 This is the main part of the bug fix.

2490 * buffer.c (buffer_slot_type_mismatch): Remove.
2491 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to

2495 left-margin-width, right-margin-width, left-fringe-width,
2496 right-fringe-width, scroll-bar-width and buffer-display-count.
2497 Use Qstringp for default-directory, buffer-file-name,
2498 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2499 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for

2518 (make_gap_1): New function to adjust the gap of any buffer.
2519 * coding.c (coding_alloc_by_making_gap): Use it.
2520 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,

2544 trailing dash is properly added.
2546 2013-01-05 Eli Zaretskii <eliz@gnu.org>

2549 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2550 digits for buffer positions, before misalignment starts.
2551 Display "0" for integer "object" field.
2552 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2553 Display the newline glyph more unambiguously.
2555 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2557 * nsterm.m (ns_draw_underwave):
2558 * w32term.c (w32_draw_underwave):
2559 * xterm.c (x_draw_underwave): Make underwave look more triangular
2560 and also degrade gracefully for small fonts. (Bug#13000)
2562 * nsterm.m (ns_draw_text_decoration):
2563 * w32term.c (x_draw_glyph_string):
2564 * xterm.c (x_draw_glyph_string): Don't use previous underline
2565 thickness and position if previous underline type is underwave.
2567 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
2569 * fileio.c (Ffile_acl): Undocument return format.
2571 2013-01-02 Glenn Morris <rgm@gnu.org>
2573 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

2585 * term.c (tty_ins_del_lines):
2586 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2587 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2589 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2591 * w32.c (unsetenv): Set up the string passed to _putenv
2593 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2594 for the bug this caused.
2596 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2598 * coding.c (Qmac): Now static.
2600 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2602 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2603 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

2612 Check toolbar_is_packed.
2613 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2614 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2615 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2617 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2618 (xg_update_menubar): Update title only if
2619 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2620 (xg_update_submenu): Skip tearoff only if
2621 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2622 (xg_initialize): Initialize xg_detached_menus only if
2623 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2625 * xterm.h (struct x_output): Surround handlebox_widget with
2626 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2627 toolbar_in_hbox is bool.
2629 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2631 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2632 (LIBS_GNUSTEP): Define.
2633 (LIBES): Add $(LIBS_GNUSTEP).

2636 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2638 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2639 continuation glyph on a TTY with an indication of an empty line.
2642 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2644 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2645 file's SELinux context or ACLs successfully set, nil otherwise.
2647 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
2649 * w32proc.c (reader_thread): Avoid passing NULL handles to
2650 SetEvent and WaitForSingleObject.
2652 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2654 Port EXTERNALLY_VISIBLE to Clang 3.2.
2655 * conf_post.h (__has_attribute): New macro.
2656 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2658 2012-12-27 Glenn Morris <rgm@gnu.org>
2660 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2661 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2663 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2665 * fileio.c (file_name_as_directory, directory_file_name):
2666 Accept an additional argument MULTIBYTE to indicate whether the input C
2667 came from a multibyte or a unibyte Lisp string; all callers
2668 adjusted. Don't assume the input string is always multibyte.
2670 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2671 don't ENCODE_FILE them, and return a unibyte string if the input
2673 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2674 don't assume the input strings will always be multibyte. If the
2675 input strings are multibyte, decode strings obtained from C
2678 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2680 * lisp.h (toplevel): Add two notices to the comment about
2681 defining a new Lisp data type.

2685 * alloc.c (valid_lisp_object_p): Adjust comment.
2687 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2689 * keyboard.c (record_asynch_buffer_change): Initialize an event
2690 only if it's really needed.
2691 * frame.h (enum output_method): Remove output_mac member since
2692 it's a leftover from the deleted code.
2693 * frame.c (Fframep): Adjust user here ...
2694 * terminal.c (Fterminal_live_p): ... and here.
2695 * coding.c (Qmac): Now here because it's only used to denote
2696 end-of-line encoding type.
2697 (syms_of_coding): DEFSYM it.
2698 * frame.h (Qmac): Remove duplicated declaration.
2700 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2702 * window.c (select_window_1): Now static, since it's used only here.
2704 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2706 * window.c (window_body_cols): Subtract display margins from the
2707 window body width on TTYs as well. See
2708 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2709 for the original report.
2711 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2713 * xdisp.c (redisplay_window): Remove inner local variable
2714 because the outer shadowed one has the same meaning.
2715 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2717 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2718 (xg_create_tool_bar): Adjust users.
2720 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2722 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2723 * buffer.c (Fget_buffer_create): Use it to set compact field of
2724 struct buffer_text to avoid accessing an uninitialized value
2725 when compact_buffer is called for the first time.
2726 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2727 (Fset_buffer_modified_p): Use buffer_window_count to check
2728 whether the buffer is displayed in some window.
2729 * xdisp.c (message_dolog): Likewise.
2731 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2733 * w32.c (acl_set_file): If setting the file security descriptor
2734 fails, and the new DACL is identical to the existing one, silently
2735 return success. This fixes problems for users backing up their
2736 own files without having the necessary privileges for setting
2737 security descriptors.
2739 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2741 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2742 after WaitForSingleObject returns normally. This expedites reader
2743 thread shutdown when delete_child triggers it.
2744 (reap_subprocess): More accurate commentary for why we call
2745 delete_child only when cp->fd is negative.
2747 * w32.c (sys_close): Do not call delete_child on a subprocess
2748 whose handle is not yet closed. Instead, set its file descriptor
2749 to a negative value, so that reap_subprocess will call
2750 delete_child on that subprocess when its SIGCHLD arrives.
2751 This avoids closing handles used for communications between sys_select
2752 and reader_thread, which doesn't give sys_select a chance to
2753 notice that the process exited and invoke the SIGCHLD handler for
2756 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2758 * nsfns.m (Fns_do_applescript): Run event loop until script has
2759 been executed (Bug#12969).
2760 (ns_run_ascript): Chech as_script for nil, set to nil after
2763 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2765 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2767 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2769 * w32term.c (w32fullscreen_hook): New function.
2770 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2772 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2774 * fileio.c (Finsert_file_contents): Doc fix.
2776 * w32proc.c (new_child, delete_child, find_child_pid): For a
2777 subprocess, consider its slot being in use as long as its process
2778 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2779 slot when a new process is started immediately after killing
2780 another one, without waiting enough time for the first process to
2781 be reaped and resources allocated for it be orderly freed.

2797 (get_file_owner_and_group): Remove now unused argument FNAME; all
2800 2012-12-21 Chong Yidong <cyd@gnu.org>
2802 * editfns.c (Finsert_char): Since read-char-by-name now signals an

2846 * w32.c (acl_get_file, acl_set_file): Run the file name through

2863 * window.c (select_window_1): New func, extracted from select_window.
2864 (select_window): Use it.

2891 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2893 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2894 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2895 for some of that bug's symptoms can now cause Emacs to abort.
2896 Remove the workaround.
2897 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2898 The bug that caused SIGCHLD to get lost has been fixed, and the
2899 workaround for it can now cause Emacs to abort.
2901 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2903 * sysdep.c (emacs_abort): Bump backtrace size to 40.

2946 asynchronous subprocess, record the name of the input file name,
2948 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2949 delete the file, record it as pending deletion when the subprocess

2960 Fix permissions bugs with setgid directories etc. (Bug#13125)
2961 * dired.c (Ffile_attributes): Return t as the 9th attribute,

2972 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2974 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2975 try to get accurate owner and group information from NT file
2976 security APIs. This is to make most callers of 'stat' and
2977 'lstat', which don't need that information, much faster.
2979 * dired.c (Ffile_attributes) [WINDOWSNT]:
2980 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2981 owner and group information from 'lstat'.
2983 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2985 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2986 as that confuses set-auto-coding, so insist on the head-read

3011 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
3012 files, fixing a regression from 24.2.
3013 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3015 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3017 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3018 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3019 Remove unnecessary S_ISLNK test, as (contra the comments) this
3020 function can't copy symlinks. Improve quality of error message
3021 when attempting to copy files that are neither regular files nor

3040 * inotify.c (inotify_callback): Generate an Emacs event for every
3041 incoming inotify event.
3043 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3045 * xdisp.c (handle_face_prop): Fix logic of computing
3046 it->start_of_box_run_p.
3047 (append_space_for_newline): If the glyph row is R2L, reset the
3048 iterator's end_of_box_run_p flag before prepending the space glyph.
3049 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3050 iterator's start_of_box_run_p flag before prepending the stretch.

3052 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3053 left_box_line_p and right_box_line_p flags of the glyph for R2L
3054 glyph rows. (Bug#13011)

3264 instead, use xputenv+unsetenv to set and restore TZ.
3265 (environbuf): Remove static var. All uses removed.
3266 (Fset_time_zone_rule): Do not save TZ and environ;
3267 no longer needed here.
3268 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3269 Move to inside set_time_zone_rule; they don't need file scope any more.
3270 (set_time_zone_rule): Maintain the TZ=value string separately.
3271 (syms_of_editfns): Don't initialize initial_tz;
3272 init_editfns now does it.
3273 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3274 * lisp.h (xputenv): New decl.
3276 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
3278 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
3280 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3282 * w32.c (unsetenv, sys_putenv): New functions.
3284 2012-12-08 Chong Yidong <cyd@gnu.org>
3286 * editfns.c (Finsert_char): Make the error message more
3287 informative (Bug#12992).
3289 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3291 Simplify get_lim_data.
3292 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3293 Remove USG and vlimit methods; no longer used these days.
3294 Add #error catchall just in case.
3296 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3297 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3298 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3299 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
3300 (deleted_pid_list, Fdelete_process, create_process)
3301 (record_child_status_change, handle_child_signal, deliver_child_signal)
3302 (init_process_emacs, syms_of_process):
3303 Assume SIGCHLD is defined.
3304 (parse_signal): Remove. All uses removed.
3305 (abbr_to_signal): New static function.
3306 (Fsignal_process): Use it to convert signal names to ints.
3307 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
3308 kill (getpgrp (), ...).
3309 (emacs_sigaction_init): Assume SIGCHLD is defined.
3310 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
3311 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
3312 * syssignal.h (EMACS_KILLPG): Remove.
3313 All uses replaced by 'kill' with a negative pid.
3314 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
3315 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
3317 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3319 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3320 This will cause a production Emacs to dump core instead of
3323 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3325 * frame.c (make_frame): Do not set window's buffer to t.
3326 * window.c (Fsplit_window_internal): Likewise. Previously it was
3327 used to indicate that the window is being set up. Now we use
3328 set_window_buffer for all new windows, so the condition in ...
3329 (Fset_window_buffer): ... is always true and can be removed.
3331 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3333 Convenient macro to check whether the buffer is hidden.
3334 * buffer.h (BUFFER_HIDDEN_P): New macro.
3335 * frame.c (make_frame): Use it. Adjust comment.
3336 * buffer.c (candidate_buffer): New function.
3337 (Fother_buffer, other_buffer_safely): Use it.
3339 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3341 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3342 if the child process is still running. Instead, exit the wait
3343 loop and return zero. (Bug#13086)
3345 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3347 * frame.h (x_char_width, x_char_height): Remove prototypes.
3348 * w32term.h (x_char_width, x_char_height): Likewise.
3349 * xfns.c (x_char_width, x_char_height): Remove.
3350 * w32fns.c (x_char_width, x_char_height): Likewise.
3351 * nsfns.c (x_char_width, x_char_height): Likewise.
3352 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
3354 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
3355 * keyboard.c (command_loop_1): Remove prototype.

3358 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
3360 Fix a recently-introduced delete-process race condition.
3361 * callproc.c, process.h (record_kill_process):
3362 New function, containing part of the old call_process_kill.
3363 (call_process_kill): Use it.
3364 This does not change call_process_kill's behavior.
3365 * process.c (Fdelete_process): Use record_kill_process to fix a
3366 race condition that could cause Emacs to lose track of a child.
3368 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3370 Avoid code duplication between prev_frame and next_frame.
3371 * frame.c (candidate_frame): New function. Add comment.
3372 (prev_frame, next_frame): Use it. Adjust comment.
3374 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3376 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3377 fails, signal an error instead of continuing with an empty
3379 Encode expanded temp file pattern before passing it to mkstemp or
3382 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3383 Encode the file name before passing it to dostounix_filename, in
3384 case it will downcase it (under w32-downcase-file-names).
3387 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3389 Minor call-process cleanups.
3390 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3391 at the same time as other platforms, to simplify analysis.
3392 No need for fd0_volatile since we have synch_process_fd.
3393 Avoid needless emacs_close; arg is always negative.
3395 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3397 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3400 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3402 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3403 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3404 and mouse_face_hidden members to a bitfields.
3405 * frame.h (struct frame): Remove set-but-not-used space_width member.
3406 (FRAME_SPACE_WIDTH): Remove.
3407 * nsterm.m, w32term.c, xterm.c: Adjust users.
3408 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3409 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3410 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3411 members to a bitfields.
3413 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3415 Don't let call-process be a zombie factory (Bug#12980).
3416 Fixing this bug required some cleanup of the signal-handling code.
3417 As a side effect, this change also fixes a longstanding rare race
3418 condition whereby Emacs could mistakenly kill unrelated processes,
3419 and it fixes a bug where a second C-g does not kill a recalcitrant
3420 synchronous process in GNU/Linux and similar platforms.
3421 The patch should also fix the last vestiges of Bug#9488,
3422 a bug which has mostly been fixed on the trunk by other changes.
3423 * callproc.c, process.h (synch_process_alive, synch_process_death)
3424 (synch_process_termsig, sync_process_retcode):
3425 Remove. All uses removed, to simplify analysis and so that
3426 less consing is done inside critical sections.
3427 * callproc.c (call_process_exited): Remove. All uses replaced
3428 with !synch_process_pid.
3429 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3430 These take the role of what used to be in unwind-protect arg.
3432 (block_child_signal, unblock_child_signal):
3433 New functions, to avoid races that could kill innocent-victim processes.
3434 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3435 (call_process_kill): Record killed processes as deleted, so that
3436 zombies do not clutter up the system. Do this inside a critical
3437 section, to avoid a race that would allow the clutter.
3438 (call_process_cleanup): Fix code so that the second C-g works again
3439 on common platforms such as GNU/Linux.
3440 (Fcall_process): Create the child process in a critical section,
3441 to fix a race condition. If creating an asynchronous process,
3442 record it as deleted so that zombies do not clutter up the system.
3443 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3444 light of these changes. Omit unnecessary call to emacs_close
3445 before failure, as the unwind-protect code does that.
3446 * callproc.c (call_process_cleanup):
3447 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3448 * process.c (record_deleted_pid): New function, containing
3449 code refactored out of Fdelete_process.
3450 (Fdelete_process): Use it.
3451 (process_status_retrieved): Remove. All callers changed to use
3452 child_status_change.
3453 (record_child_status_change): Remove, folding its contents into ...
3454 (handle_child_signal): ... this signal handler. Now, this
3455 function is purely a handler for SIGCHLD, and is not called after
3456 a synchronous waitpid returns; the synchronous code is moved to
3457 wait_for_termination. There is no need to worry about reaping
3458 more than one child now.
3459 * sysdep.c (get_child_status, child_status_changed): New functions.
3460 (wait_for_termination): Now takes int * status and bool
3461 interruptible arguments, too. Do not record child status change;
3462 that's now the caller's responsibility. All callers changed.
3463 Reimplement in terms of get_child_status.
3464 (wait_for_termination_1, interruptible_wait_for_termination):
3465 Remove. All callers changed to use wait_for_termination.
3466 * syswait.h: Include <stdbool.h>, for bool.
3467 (record_child_status_change, interruptible_wait_for_termination):
3469 (record_deleted_pid, child_status_changed): New decls.
3470 (wait_for_termination): Adjust to API changes noted above.
3472 * bytecode.c, lisp.h (Qbytecode): Remove.
3473 No longer needed after 2012-11-20 interactive-p changes.
3475 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3477 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3478 the scroll margin, move point outside the margin. (Bug#13055)
3480 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3482 * gtkutil.c (my_log_handler): New function.
3483 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3485 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3487 * lisp.h (modify_region): Rename to...
3488 (modify_region_1): ...new prototype.
3489 * textprop.c (modify_region): Now static. Adjust users.
3490 * insdel.c (modify_region): Rename to...
3491 (modify_region_1): ...new function to work with current buffer.
3492 Adjust comment and users. Use true and false for booleans.
3494 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3496 * alloc.c (free_save_value): New function.
3497 (safe_alloca_unwind): Use it.
3498 * lisp.h (free_save_value): New prototype.
3499 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3501 (save_excursion_restore): Adjust to match saved data structure.
3502 Use free_save_value to offload some work from GC. Drop obsolete
3505 2012-12-03 Chong Yidong <cyd@gnu.org>
3507 * fileio.c (Vauto_save_list_file_name): Doc fix.
3509 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3511 * w32fns.c: Remove prototype of atof.
3512 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3514 (file_dialog_callback): Make it UINT_PTR.
3516 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3519 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3520 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3523 2012-12-03 Glenn Morris <rgm@gnu.org>
3525 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3527 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3529 Fix xpalloc confusion after memory is exhausted.
3530 * alloc.c (xpalloc): Comment fix.
3531 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3532 and signals an error, do not clear charset_table_size, as
3533 charset_table is still valid.
3534 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3536 Use execve to avoid need to munge environ (Bug#13054).
3537 * callproc.c (Fcall_process):
3538 * process.c (create_process):
3539 Don't save and restore environ; no longer needed.
3540 * callproc.c (child_setup):
3541 Use execve, not execvp, to preserve environ.
3543 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3545 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3547 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3549 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3550 display for sliced images (Bug#10500).
3552 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3554 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3556 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3557 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3559 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3561 * xdisp.c (window_outdated): Remove eassert since it hits
3562 some suspicious corner cases (see Bug#13007 and Bug#13012).
3563 (mode_line_update_needed): New function.
3564 (redisplay_internal, redisplay_window): Use it.
3565 (ensure_selected_frame): New function.
3566 (redisplay_internal, unwind_redisplay): Use it.
3567 (redisplay_internal): Move comment about buffer_shared...
3568 (buffer_shared_and_changed): ...near to its real use.
3570 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3572 * callproc.c (Fcall_process): Don't misreport vfork failure.
3574 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3576 * callproc.c (Fcall_process): Fix vfork portability problems.
3577 Do not assume that fd[0], count, filefd, and save_environ survive
3578 vfork. Fix bug whereby wrong errno value could be reported for
3579 pipe failure. Some minor cleanups, too, as follows. Move buf and
3580 bufsize to the context where they're needed. Change new_argv to
3581 be of type char **, as this is more convenient and avoids casts.
3582 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3583 Now local constants, not macros.
3585 2012-11-18 Kenichi Handa <handa@gnu.org>
3587 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3588 for the variable "f".
3590 2012-11-13 Kenichi Handa <handa@gnu.org>
3592 * font.c (font_unparse_xlfd): Exclude special characters from the
3593 generating XLFD name.
3595 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3597 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

3608 * lread.c (readbyte_from_file): Assume EINTR is defined.
3609 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3610 Assume EIO and EAGAIN are defined.
3611 * unexcoff.c (write_segment): Assume EFAULT is defined.
3613 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3615 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3618 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3619 highlighting on the frame was cleared. Prevents assertion
3620 violations when repeatedly clicking on the "Top" link of the
3621 "bread-crumbs" in Info buffers.
3623 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
3625 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
3627 2012-11-24 Ken Brown <kbrown@cornell.edu>
3629 * keyboard.c (HAVE_MOUSE):
3630 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3631 were always defined.
3633 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3635 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3636 between bpos_covered and bpos_max. This fixes cursor display when
3637 several display strings follow each other.
3639 * .gdbinit (pgx): If the glyph's object is a string, display the
3640 pointer to string data, rather than the value of the string object
3641 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3643 * indent.c (Fvertical_motion): If the starting position is covered
3644 by a display string, return to one position before that, to avoid
3645 overshooting it inside move_it_to. (Bug#12930)
3647 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3649 * frame.h (struct frame): Remove display_preempted member

3652 * w32menu.c (pending_menu_activation): Remove since not
3654 (set_frame_menubar): Adjust user.
3655 * w32term.h (struct x_output): Drop outdated #if 0 code.
3656 (struct w32_output): Use bitfields for explicit_parent,
3657 asked_for_visible and menubar_active members.
3658 Drop unused pending_menu_activation member.
3659 * xterm.h (struct x_output): Drop outdated #if 0 code.
3660 Use bitfields for explicit_parent, asked_for_visible,
3661 has_been_visible and net_wm_state_hidden_seen members.
3663 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3665 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3666 of a literal "/". (Bug#12955)
3667 (gl-stamp): Invoke fc.exe directly, not through cmd.
3669 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3671 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3672 * dired.c: Assume HAVE_DIRENT_H.
3673 (NAMLEN): Remove, replacing with ...
3674 (dirent_namelen): New function. All uses changed. Use the GNU macro
3675 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3676 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3677 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3678 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3680 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3681 * ndir.h: Rename to ../nt/inc/dirent.h.
3682 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3683 Do not include <dirent.h>; no longer needed.
3684 * w32.c: Include <dirent.h> rather than "ndir.h".
3686 2012-11-23 Chong Yidong <cyd@gnu.org>
3688 * xftfont.c (xftfont_open): Remove duplicate assignment.
3690 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3692 * alloc.c (Fgarbage_collect): Unblock input after clearing
3693 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3694 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3695 * msdos.c (IT_frame_up_to_date): Use it here...
3696 * w32term.c (w32_frame_up_to_date): ...here...
3697 * xterm.c (XTframe_up_to_date): ...and here...
3698 * nsterm.m (ns_frame_up_to_date): ...but not here.
3699 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3701 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3702 Do not check whether GC is in progress.
3704 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3706 * xdisp.c (window_buffer_changed): New function.
3707 (update_menu_bar, update_tool_bar): Use it to
3708 simplify large 'if' statements.
3709 (redisplay_internal): Generalize commonly used
3710 'tail' and 'frame' local variables.
3712 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3714 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3715 with Windows system header.

3719 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3720 * alloc.c: Assume unistd.h exists.
3721 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3722 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3723 (getwd) [USG]: Remove; no longer needed.
3724 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3725 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3726 * w32.h (getcwd): Remove decl.
3728 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3730 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3731 Make it set selected_window as well.
3732 (update_tool_bar): Use it.
3734 2012-11-21 Ken Brown <kbrown@cornell.edu>
3736 * emacs.c (main): Set the G_SLICE environment variable for all
3737 Cygwin builds, not just GTK builds. See
3738 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3740 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3742 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3743 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3744 Define for the MSVC compiler.
3746 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3748 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3749 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3750 dostounix_filename. Prevents crashes down the road, because
3751 dostounix_filename assumes it gets a unibyte string.
3752 Reported by Michel de Ruiter <michel@sentient.nl>, see

3759 * lread.c (init_obarray): Set `function' fields to Qnil.
3760 * eval.c (Fcommandp): Ignore Qunbound.
3761 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3762 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3763 Test NILP rather than Qunbound.
3764 (Ffmakunbound): Set to Qnil.
3765 (Fsymbol_function): Never signal an error.
3766 (Finteractive_form): Ignore Qunbound.
3768 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3770 * eval.c (interactive_p): Remove no-longer-used decl.
3772 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3774 * xdisp.c (buffer_shared): Adjust comment.
3775 (buffer_shared_and_changed): New function.
3776 (prepare_menu_bars, redisplay_internal): Use it to
3777 decide whether all windows or frames should be updated.
3778 (window_outdated): New function.
3779 (text_outside_line_unchanged_p, redisplay_window): Use it.
3780 (redisplay_internal): Likewise. Fix indentation.
3782 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3784 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3785 (syms_of_eval): Remove corresponding defsubr.
3786 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3788 2012-11-19 Daniel Colascione <dancol@dancol.org>
3790 * w32fns.c (Fx_file_dialog):
3791 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3792 cygwin_convert_file_name*.
3794 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3795 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3797 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3799 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3801 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3803 * w32select.c: Include w32common.h before w32term.h, so that
3804 windows.h gets included before w32term.h uses some of its
3805 features, see below.
3807 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3809 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3811 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3813 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3815 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3816 (ns_select): Return at once if events are held (Bug#12834).
3818 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3820 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3821 Needed following 2012-10-20 change. (Bug#12902)
3823 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3825 * w32proc.c (waitpid): Remove unused label get_result.
3827 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3829 * makefile.w32-in (SYSWAIT_H): New macro.
3830 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3831 ($(BLD)/sysdep.$(O)): Update dependencies.
3833 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3835 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3836 * callproc.c (relocate_fd): Assume F_DUPFD.
3837 * emacs.c, term.c (O_RDWR): Remove.
3838 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3839 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3840 * nsterm.m: Assume <fcntl.h> exists.
3841 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3842 (create_pty, Fmake_network_process, server_accept_connection)
3843 (wait_reading_process_output, init_process_emacs):
3845 (wait_reading_process_output): Put in a special case for WINDOWSNT
3846 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3847 It's not clear this is needed, but it's a more-conservative change.
3848 (create_process): Assume FD_CLOEXEC.
3849 (create_process, create_pty): Assume O_NOCTTY.
3850 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3851 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3852 Omit if not DOS_NT, since F_GETFL is not defined there.
3853 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3854 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3856 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3857 lack it, since gnulib guarantees this.
3858 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3860 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3862 * w32.c (faccessat): Pretend that directories have the execute bit
3863 set. Emacs expects that, e.g., in files.el:cd-absolute.
3865 * w32proc.c (create_child): Don't clip the PID of the child
3866 process to fit into an Emacs integer, as this is no longer a
3868 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3869 reaping only the process specified by PID argument, if that is
3870 positive. Use PID instead of dead_child to know which process to
3871 reap. Wait for the child to die only if WNOHANG is not in
3873 (sys_select): Don't set dead_child.
3875 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3876 as it is no longer needed.
3878 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3880 (record_child_status_change): Remove the setting of
3881 record_at_most_one_child for the !WNOHANG case.
3883 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3885 Fix problems in ns port found by static checking.
3886 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3887 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3888 not to process group.
3889 (ns_select): Use emacs_write, not write, as that's more robust
3890 in the presence of signals.
3891 (fd_handler:): Check for read errors.
3893 2012-11-16 Glenn Morris <rgm@gnu.org>
3895 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3897 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3899 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3901 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3903 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3904 use the same value of thread handle.
3905 (start_timer_thread): If the timer thread exited (due to error),
3906 clean up by closing the two handles it used. Duplicate the caller
3907 thread's handle here, so it gets duplicated only once, when
3908 launching the timer thread. Set priority of the timer thread, not
3910 (getitimer): Don't duplicate the caller thread's handle here.
3913 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3915 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3918 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3920 Remove no-longer-used pty_max_bytes variable.
3921 * process.c (pty_max_bytes): Remove; unused.
3922 (send_process): Do not set it.
3924 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3926 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3927 Update dependencies.
3929 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3931 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3932 This follows up on the 2012-09-29 patch that removed indirection
3933 for the 'function' field. Reported by Sergey Vinokurov in
3934 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3936 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3938 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3939 different name, as the MS runtime does not have such a function,
3940 and probably never will.) All callers changed. Ignore DIRFD
3941 value if PATH is an absolute file name, to match Posix spec
3942 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3945 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3947 * xdisp.c (echo_area_display, redisplay_internal):
3948 Omit redundant check whether frame_garbaged is set.
3950 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3952 Use faccessat, not access, when checking file permissions (Bug#12632).
3953 This fixes a bug that has been present in Emacs since its creation.
3954 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3955 which must set some sort of record. (Torek's bug report was against
3956 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3957 same common flaw.) See Torek's Usenet posting
3958 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3959 Posted: Fri Apr 8 14:18:56 1983.
3960 * Makefile.in (LIB_EACCESS): New macro.
3962 * callproc.c (init_callproc):
3963 * charset.c (init_charset):
3964 * fileio.c (check_existing, check_executable, check_writable)
3966 * lread.c (openp, load_path_check):
3967 * process.c (allocate_pty):
3969 Use effective UID when checking permissions, not real UID.
3970 * callproc.c (init_callproc):
3971 * charset.c (init_charset):
3972 * lread.c (load_path_check, init_lread):
3973 Test whether directories are accessible, not merely whether they exist.
3974 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3975 * fileio.c (check_existing, check_executable, check_writable)
3977 Use symbolic names instead of integers for the flags, as they're
3979 (check_writable): New arg AMODE. All uses changed.
3980 Set errno on failure.
3981 (Ffile_readable_p): Use faccessat, not stat + open + close.
3982 (Ffile_writable_p): No need to call check_existing + check_writable.
3983 Just call check_writable and then look at errno. This saves a syscall.
3984 dir should never be nil; replace an unnecessary runtime check
3985 with an eassert. When checking the parent directory of a nonexistent
3986 file, check that the directory is searchable as well as writable, as
3987 we can't create files in unsearchable directories.
3988 (file_directory_p): New function, which uses 'stat' on most platforms
3989 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3990 (Ffile_directory_p, Fset_file_times): Use it.
3991 (file_accessible_directory_p): New function, which uses a single
3992 syscall for efficiency.
3993 (Ffile_accessible_directory_p): Use it.
3994 * xrdb.c (file_p): Use file_directory_p.
3995 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3996 * lread.c (openp): When opening a file, use fstat rather than
3997 stat, as that avoids a permissions race. When not opening a file,
3998 use file_directory_p rather than stat.
3999 (dir_warning): First arg is now a usage string, not a format.
4000 Use errno. All uses changed.
4001 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
4002 that merely introduced a race.
4003 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
4004 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4005 and similarly for the other O_* flags.
4006 * w32.c (sys_faccessat): Rename from sys_access and switch to
4007 faccessat's API. All uses changed.
4008 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4009 (magic_db): Rename from magic_file_p.
4010 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4011 char *, so that we don't have to test for file existence
4012 separately from opening the file for reading. This removes a race
4013 fixes a permission-checking problem, and simplifies the code.
4015 (file_p): Remove; no longer needed.
4017 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4019 Omit glyphs initialization at startup.
4020 * dispnew.c (glyphs_initialized_initially_p): Remove.
4021 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4022 (Fredraw_frame): Move actual code from here...
4023 (redraw_frame): ...to here. Add eassert. Adjust comment.
4024 (Fredraw_display): Use redraw_frame.
4025 * xdisp.c (clear_garbaged_frames): Likewise.
4027 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4029 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4030 passed to pint2str and pint2hrstr to be at most the size of the
4031 frame's decode_mode_spec_buffer. This avoids crashes with very
4032 large values of FIELD_WIDTH argument to decode_mode_spec.
4035 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4037 Fix a race with verify-visited-file-modtime (Bug#12863).
4038 Since at least 1991 Emacs has ignored an mtime difference of no
4039 more than one second, but my guess is that this was to work around
4040 file system bugs that were fixed long ago. Since the race is
4041 causing problems now, let's remove that code.
4042 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4043 whose time stamp is off by no more than a second. Insist that the
4044 file time stamps match exactly.
4046 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4048 * frame.h (struct frame): Convert external_tool_bar member to
4049 1-bit unsigned bitfield.
4050 * termhooks.h (struct terminal): Remove mouse_moved member since
4051 all users are long dead. Adjust comment on mouse_position_hook.
4053 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4055 Simplify by using FOR_EACH_FRAME here and there.
4056 * frame.c (next_frame, prev_frame, other_visible_frames)
4057 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4058 * w32term.c (x_window_to_scroll_bar): Likewise.
4059 * window.c (window_list): Likewise.
4060 * xdisp.c (x_consider_frame_title): Likewise.
4061 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4062 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4063 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4064 * xmenu.c (menubar_id_to_frame): Likewise.
4065 * xselect.c (frame_for_x_selection): Likewise.
4066 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4067 (x_window_to_menu_bar): Likewise.
4068 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4070 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4072 * data.c (Qdefalias_fset_function): Now static.
4074 Another tweak to vectorlike_header change.
4075 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4076 Remove, and replace all uses with ...
4077 (next_in_free_list, set_next_in_free_list):
4078 New functions, which respect C's aliasing rules better.
4080 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4082 * window.c (list4i): Rename from 'quad'. All uses changed.
4083 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4085 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4087 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4088 warning about mixing declarations and code in ISO C90.
4090 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4092 * window.c (Fsplit_window_internal): Set combination limit of
4093 new parent window to t iff Vwindow_combination_limit is t;
4094 fixing a regression introduced with the change from 2012-09-22.
4095 (Fset_window_combination_limit): Fix doc-string.
4097 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4099 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4100 amount when the scroll margins are too large. When scrolling
4101 backwards in the buffer, give up if cannot reach point or the
4102 scroll margin within a reasonable number of screen lines.
4103 Fixes point position in window under scroll-up/down-aggressively when
4104 point is positioned many lines beyond the window top/bottom.
4107 * ralloc.c (relinquish): If real_morecore fails to return memory
4108 to the system, don't crash; instead, leave the last heap
4109 unchanged and return. (Bug#12774)
4111 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4113 * lisp.h (AUTOLOADP): New macro.
4114 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
4115 * data.c (Ffset): Remove special ad-advice-info handling.
4116 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
4118 (Finteractive_form): Simplify.
4119 (Fquo): Don't insist on having at least 2 arguments.
4120 (Qdefalias_fset_function): New var.
4122 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4124 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4126 * nsfont.m (Qcondensed, Qexpanded): New variables.
4127 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
4128 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4130 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4132 Fix recently introduced crash on MS-Windows (Bug#12839).
4133 * w32term.h (struct scroll_bar): Use convenient header.
4134 (SCROLL_BAR_VEC_SIZE): Remove.
4135 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4137 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4139 Tweak last vectorlike_header change.
4140 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4141 vectorlike object on the free list. This is introduced to avoid
4142 some (but not all) pointer casting and aliasing problems, see
4143 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4144 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
4146 (xvectype, xvecsize): Use them to examine Lisp_Object values.
4148 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4150 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4151 been removed, so remove them here also.
4153 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4155 * doc.c (Fdocumentation): Handle new property
4156 dynamic-docstring-function to replace the old ad-advice-info.
4158 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4160 * fns.c (Qeql, hashtest_eq): Now static.
4162 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4164 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4165 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4166 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

4173 * lisp.h (sxhash_combine): New inline function, with the contents
4174 of the old SXHASH_COMBINE.
4175 * profiler.c (hashfn_profiler): Use it, instead of having a
4176 special hash function containing a comparison that always yields 1.
4178 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4180 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4181 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4182 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4185 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4187 * image.c (xpm_make_color_table_h): Fix compiler error because
4188 make_hash_table changed.
4190 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4192 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4194 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4196 Use ad-hoc comparison function for the profiler's hash-tables.
4197 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4198 (make_log): Use them.
4199 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4200 call Fequal any more.

4209 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4210 (hash_lookup, hash_remove_from_table): Move assertion checking of
4211 hashfn result here. Check hash-equality before calling cmpfn.

4221 2012-11-08 Eli Zaretskii <eliz@gnu.org>
4223 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4224 value of w32-scroll-lock-modifier is neither nil nor one of the
4225 known key modifiers. (Bug#12806)
4227 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4229 Shrink struct vectorlike_header to the only size field.
4230 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4232 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4233 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4234 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4235 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4236 information from the vector header. Adjust comment.

4251 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4252 (large_vectors): Change type to struct large_vector.
4253 (allocate_vector_from_block): Simplify.
4254 (PSEUDOVECTOR_NBYTES): Replace with...
4255 (vector_nbytes): ...new function. Adjust users.
4256 (sweep_vectors): Adjust processing of large vectors.
4257 (allocate_vectorlike): Likewise.
4258 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4259 Add easserts. Adjust XSETPVECTYPESIZE usage.
4260 (allocate_buffer): Use BUFFER_PVEC_INIT.
4261 (live_vector_p): Adjust to match large vector.
4262 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4263 * buffer.h (struct buffer): Add next member.
4264 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4266 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

4272 (xvecsize): New command.
4274 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4276 * keyboard.c (event_to_kboard): Do not dereference
4277 frame_or_window field of SELECTION_REQUEST_EVENT
4278 and SELECTION_CLEAR_EVENT events (Bug#12814).
4279 * xterm.h (struct selection_input_event): Adjust comment.
4281 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4283 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4284 such as Scroll Lock, if the respective keys are treated as
4285 function keys, not as modifiers. This avoids destroying non-ASCII
4286 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4288 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4290 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4292 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4294 Restore some duplicate definitions (Bug#12814).
4295 This undoes part of the 2012-11-03 changes. Some people build
4296 with plain -g rather than with -g3, and they need the duplicate
4297 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4298 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4299 Define as macros, as well as as enums or as constants.
4301 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4303 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4304 to keypad keys (Bug#12816).
4306 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4308 Minor adjustments of recently-changed frame functions.
4309 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4310 known to be a frame (we're in the FRAMEP branch).
4311 * lisp.h (Qframep): Remove decl. frame.h declares this.
4312 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4313 since they're meant for Lisp fixnum values.
4315 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4317 * window.c (Fwindow_combination_limit): Revert to the only
4318 required argument and adjust docstring as suggested in
4319 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4320 by Martin Rudalics <rudalics@gmx.at>.
4322 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4324 Widely used frame validity and checking functions.
4325 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4326 * frame.c (decode_live_frame, decode_any_frame): New functions.
4327 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4328 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4329 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

4337 * lisp.h (frame_buffer_predicate): Remove prototype.
4338 * buffer.c (Fother_buffer): Use decode_any_frame.
4339 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4340 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4341 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4342 (Fclose_font, Ffont_info): Use decode_live_frame.
4343 * fontset.c (check_fontset_name): Likewise.
4344 * terminal.c (Fframe_terminal): Likewise.
4345 * w32fns.c (check_x_frame): Likewise.
4346 * window.c (Fminibuffer_window, Fwindow_at)
4347 (Fcurrent_window_configuration): Likewise.
4348 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4349 Likewise. Allow zero number of arguments. Adjust docstring.
4350 * dispnew.c (Fredraw_frame): Likewise.
4351 * xfaces.c (frame_or_selected_frame): Remove.
4352 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4353 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4354 (Fframe_face_alist): Use decode_live_frame.
4355 * xfns.c (check_x_frame): Likewise.
4357 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4359 * window.c (quad): New function.
4360 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4361 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4362 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4363 (Fwindow_line_height): Use it.
4364 (Fwindow_fringes): Use list3.
4365 (Fwindow_scroll_bars): Use list4.
4366 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4367 (Fwindow_combination_limit): Allow zero number of arguments.
4369 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4371 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4373 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4374 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4375 file descriptor 2 for standard error. (Bug#12805)
4377 2012-11-05 Chong Yidong <cyd@gnu.org>
4379 * process.c (wait_reading_process_output): Revert previous change.
4381 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4383 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4384 This removes code that has been obsolete since around 1990.
4385 * callproc.c (Fcall_process):
4387 * process.c (create_process):
4388 * term.c (dissociate_if_controlling_tty):
4389 Assume setsid exists.
4390 * callproc.c (child_setup): Assume setpgid exists and behaves as
4391 per POSIX.1-1988 or later.
4392 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4393 * emacs.c (shut_down_emacs):
4394 * sysdep.c (sys_suspend, init_foreground_group):
4395 Assume getpgrp behaves as per POSIX.1-1998 or later.
4396 * msdos.c (setpgrp): Remove.
4397 (tcgetpgrp, setpgid, setsid): New functions.
4398 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4399 * term.c (no_controlling_tty): Remove; unused.
4400 * w32proc.c (setpgrp): Remove.
4401 (setsid, tcgetpgrp): New functions.
4403 Simplify by assuming __fpending.
4404 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4405 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4406 Do not assume that __fpending's result fits in int.
4408 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4410 Remove EMACS_OUTQSIZE+sleep hack.
4411 * dispnew.c (update_frame_1): Remove hack for terminals slower
4412 than 2400 bps, which throttled Emacs by having it sleep.
4413 This code hasn't worked since at least 2007, when the multi-tty stuff
4414 was added, and anyway those old terminals are long dead.
4415 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4416 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4418 Fix data-loss with --version (Bug#9574).
4419 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4420 as we can't assume that emacs_strerror is initialized, and strerror
4421 is good enough here.
4422 (main): Invoke atexit earlier, to catch earlier instances of
4423 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4425 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4427 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4428 (keyDown): Remap keypad keys to X11 virtual key codes.
4430 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4432 Fix data-loss with --batch (Bug#9574).
4433 * emacs.c: Include <close-stream.h>.
4434 (close_output_streams): New function.
4435 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4436 and handles errors appropriately.
4437 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4440 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4441 The symptom is a diagnostic "GLib-WARNING **: In call to
4442 g_spawn_sync(), exit status of a child process was requested but
4443 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4444 waitpid(), so exit status can't be returned." The diagnostic
4445 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4446 The real bug is a race condition between Emacs and glib: Emacs
4447 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4448 so that glib can't find it. Work around the bug by invoking
4449 waitpid only on subprocesses that Emacs itself creates.
4450 * process.c (create_process, record_child_status_change):
4451 Don't use special value -1 in pid field, as the caller now must
4452 know the pid rather than having the callee infer it.
4453 The inference was sometimes incorrect anyway, due to another race.
4454 (create_process): Set new 'alive' member if child is created.
4455 (process_status_retrieved): New function.
4456 (record_child_status_change): Use it.
4457 Accept negative 1st argument, which means to wait for the
4458 processes that Emacs already knows about. Move special-case code
4459 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4460 processes that have already been waited for, by testing and
4461 clearing new 'alive' member.
4462 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4463 now does this internally.
4464 (handle_child_signal): Let record_child_status_change do all
4465 the work, since we do not want to reap all exited child processes,
4466 only the child processes that Emacs itself created.
4467 * process.h (Lisp_Process): New boolean member 'alive'.
4469 Omit duplicate definitions no longer needed with gcc -g3.
4470 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4471 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4472 Define only as macros. There's no longer any need to also define
4473 these symbols as enums or as constants, since we now assume
4474 gcc -g3 when debugging.
4476 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4478 * lisp.mk: Adjust comments to the fact that term/internal is now
4479 loaded from loadup.el.
4481 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4482 (msdos_fatal_signal): New function.
4483 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4486 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4487 for GCC versions before 4.
4488 (emacs_raise): Define to call msdos_fatal_signal.
4490 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4491 iterator when starting in the middle of a display or overlay
4494 2012-11-03 Chong Yidong <cyd@gnu.org>
4496 * process.c (wait_reading_process_output): Clean up the last
4499 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4501 * process.c (wait_reading_process_output): Avoid a race condition
4502 with SIGIO delivery (Bug#11536).
4504 2012-11-03 Chong Yidong <cyd@gnu.org>
4506 * buffer.c (cursor_type): Untabify docstring.
4508 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4510 * frame.h (struct frame): Drop can_have_scroll_bars member
4511 which is meaningless for a long time. Adjust comments.
4512 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4513 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4515 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4517 * window.c (decode_next_window_args): Update window arg after
4518 calling decode_live_window and so fix crash reported at
4519 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4520 by Juanma Barranquero <lekktu@gmail.com>.
4521 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4522 * font.c (Ffont_at): Likewise.
4524 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4526 * widget.c (resize_cb): New function.
4527 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4528 (EmacsFrameResize): Check if all is up to date before changing frame
4531 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4533 Implement backtrace output for fatal errors on MS-Windows.
4534 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4535 (BACKTRACE_LIMIT_MAX): New macro.
4536 (w32_backtrace): New function.
4537 (emacs_abort): Use w32_backtrace when the user chooses not to
4538 attach a debugger. Update the text of the abort dialog.
4540 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4542 Window-related stuff cleanup here and there.
4543 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4544 Use decode_any_window.
4545 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4546 * xdisp.c (Fformat_mode_line): Likewise.
4547 * font.c (Ffont_at): Use decode_live_window.
4548 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.

4550 (decode_any_window): Remove static.
4551 * window.h (decode_any_window): Add prototype.
4552 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4553 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4556 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4558 Remove pad from struct input_event.
4559 * termhooks.h (struct input_event): Remove padding field.
4561 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4562 member is never cons for a long time. Adjust comment.
4563 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4564 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4565 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4566 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4568 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4570 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4572 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4574 Fix crash when using Emacs as commit editor for git (Bug#12697).
4575 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4576 and it is configured in conf_post.h.
4577 (Fcall_process): Don't invoke both setsid and setpgid; the former
4578 is enough, if it exists.
4579 * callproc.c (Fcall_process, child_setup):
4580 * process.c (create_process): Use setpgid.
4581 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4583 * dispnew.c (init_display): Initialize the foreground group
4584 if we are running a tty display.
4585 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4586 * lisp.h (init_foreground_group): New decl.
4587 * sysdep.c (inherited_pgroup): New static var.
4588 (init_foreground_group, tcsetpgrp_without_stopping)
4589 (narrow_foreground_group, widen_foreground_group): New functions.
4590 (init_sys_modes): Narrow foreground group.
4591 (reset_sys_modes): Widen foreground group.

4597 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4599 * minibuf.c (read_minibuf): Restore current buffer since
4600 choose_minibuf_frame calling Fset_frame_selected_window may
4601 change it (Bug#12766).
4603 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4605 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4607 2012-10-30 Kenichi Handa <handa@gnu.org>
4609 * font.c (Ffont_at): If WINDOW is specified and it is not
4610 displaying the current buffer, signal an error.
4612 2012-10-29 Daniel Colascione <dancol@dancol.org>
4614 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4615 In preparation for fixing bug#12739, move these functions from
4618 * coding.h, coding.c: ... to here, and compile them only when
4619 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4620 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4622 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4624 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4625 (timer_loop, getitimer, setitimer): Use it instead of
4626 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4628 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4631 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4633 * nsterm.m (NO_APPDEFINED_DATA): New define.
4634 (last_appdefined_event_data): New variable
4635 (last_appdefined_event): Remove.
4636 (ns_select): Initialize t from last_appdefined_event_data instead
4637 of [last_appdefined_event data1].
4638 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4639 remove last_appdefined_event (Bug#12698).
4641 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4643 * frame.c (x_set_font): Catch internal error.
4645 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4647 Avoid overflow in w32 implementation of interval timers.
4648 When possible, for ITIMER_PROF count only times the main thread
4650 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4651 'volatile ULONGLONG' types. All the other data which was
4652 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4653 (GetThreadTimes_Proc): New typedef.
4654 (w32_get_timer_time): New function, returns a suitable time value
4656 (timer_loop): Enter critical section when accessing ULONGLONG
4657 values of the itimer_data struct, as these accesses are no longer
4658 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4659 Remove unused variable.
4660 (init_timers): Initialize s_pfn_Get_Thread_Times.
4661 (start_timer_thread): Don't assign itimer->caller_thread here.
4662 (getitimer): Assign itimer->caller_thread here.

4668 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4669 mouse movement events if the menu bar is active. This avoids
4670 producing a busy "hour-glass" cursor by Windows if the mouse
4671 pointer is positioned over a tooltip shown for some menu item.
4673 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4675 Don't assume process IDs fit in int.
4676 * emacs.c (shut_down_emacs) [!DOS_NT]:
4677 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4678 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4679 Use pid_t, not int, to store process IDs, as 'int'
4680 is not wide enough on a few platforms (e.g., AIX and IRIX).
4682 2012-10-23 Kenichi Handa <handa@gnu.org>
4684 The following change is to make face-font-rescale-alist work
4685 correctly for non-ASCII fonts.
4687 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4688 (font_open_for_lface): Handle Vface_font_rescale_alist.
4690 2012-10-23 Chong Yidong <cyd@gnu.org>
4692 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4694 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

4703 2012-10-21 Glenn Morris <rgm@gnu.org>
4705 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4707 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4709 Port to OpenBSD 5.1.
4710 * frame.c (Fmouse_position, Fmouse_pixel_position):
4711 * xdisp.c (produce_stretch_glyph):
4712 Declare local vars only when they're needed.
4713 This is clearer and avoids a warning on OpenBSD about unused vars.
4714 * frame.h (FRAME_WINDOW_P): Always evaluate its argument.
4715 This is safer, and avoids OpenBSD warnings about unused vars.
4716 * keyboard.c (record_menu_key): Remove unnecessary decl.
4717 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4718 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4719 as our definition clashes with OpenBSD's.
4720 * xfaces.c (load_face_colors, check_lface_attrs)
4721 (get_lface_attributes_no_remap, get_lface_attributes)
4722 (lface_fully_specified_p, x_supports_face_attributes_p)
4723 (tty_supports_face_attributes_p, face_fontset, realize_face)
4724 (realize_x_face, realize_tty_face):
4725 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4726 merely Lisp_Object *. This is more informative and avoids
4727 a warning on OpenBSD about accessing beyond an object's size.
4729 2012-10-20 Chong Yidong <cyd@gnu.org>
4731 * lread.c (Fload): Doc fix (Bug#12592).

4735 * font.c (Ffont_at): Fix previous change.
4737 2012-10-19 Eli Zaretskii <eliz@gnu.org>
4739 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
4740 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

4757 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4758 (staticpro): If we run out of staticpro slots, die with an
4759 informative error instead of just calling emacs_abort.
4761 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4763 Fix two flaws reported by Dmitry Antipov.

5018 since unsigned is guaranteed to have that behavior and signed is not.

5020 (get_input_pending): Remove first argument, since it was always
5021 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5022 and behave as if it had that value. Return new value of
5023 input_pending. All callers changed.
5024 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5025 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

5068 match what GetLastError returns. Explain why the function is
5071 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5072 'is_tooltip_frame', to avoid confusion with its global namesake.
5074 2012-10-08 Daniel Colascione <dancol@dancol.org>
5076 * xdisp.c (start_hourglass): Call w32_note_current_window when
5077 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5078 build that caused Emacs to display the hourglass cursor forever.
5080 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5081 which is broken under remote desktop, calculate the number of
5082 colors available for a display based on the display's number of
5083 planes and number of bits per pixel per plane. (bug#10397).
5085 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5087 * nsfont.m (Vfonts_in_cache): New variable.
5088 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5089 are used. Add cached fonts to Vfonts_in_cache.
5090 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5092 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5094 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5096 (FONT_H): Define after FRAME_H.
5097 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5098 Update dependencies.
5100 * w32term.c: Remove leftover declaration of keyboard_codepage.
5102 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5104 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5105 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5106 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5107 (GLOBAL_SOURCES): Add cygw32.c.
5108 ($(BLD)/unexw32.$(O)):
5110 ($(BLD)/w32console.$(O)):
5111 ($(BLD)/w32fns.$(O)):
5112 ($(BLD)/w32heap.$(O)):
5113 ($(BLD)/w32menu.$(O)):
5114 ($(BLD)/w32proc.$(O)): Add w32common.h.
5116 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5118 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5120 2012-10-08 Daniel Colascione <dancol@dancol.org>
5122 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5123 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5124 accidental message numbering hole. Change other messages to
5127 * w32select.h (HAVE_W32SELECT): Remove.
5129 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5130 w32common.h instead of w32heap.h.
5132 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5133 (get_allocation_unit, get_processor_type, get_w32_major_version)
5134 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5135 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5136 (OS_NT, os_subtype, cache_system_info): Move declarations to
5139 * w32heap.c: Include w32common.h.
5140 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5141 (w32_minor_version, w32_build_number, w32_subtype):
5142 Remove duplicate definitions.
5144 * w32fns.c: Include w32common.h; include w32heap.h only in
5147 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5148 Use `report_file_error' instead of `error' in order to better
5149 inform users of what went wrong. Increase NTGUI_UNICODE file
5150 dialog box file name length to 32k, the maximum allowed by the NT
5153 * w32common.h: New file.
5154 (ROUND_UP, ROUND_DOWN, get_page_size)
5155 (get_allocation_unit, get_processor_type, get_w32_major_version)
5156 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5157 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5158 (OS_NT, os_subtype, cache_system_info): Move here.
5160 * unexw32.c, unexcw.c: Include w32common.h.
5162 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5163 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5164 to call syms_of_w32select.
5166 * cygw32.h: Remove obsolete EXFUN declarations.
5168 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5170 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5171 of w32inevt.o from SOME_MACHINE_OBJECTS.
5173 2012-10-08 Daniel Colascione <dancol@dancol.org>
5175 * image.c: Permanent fix for JPEG compilation issue --- limit
5176 jpeglib `boolean' redefinition to Cygwin builds.
5178 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5180 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5182 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5185 2012-10-08 Daniel Colascione <dancol@dancol.org>
5187 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5188 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5189 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5190 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5191 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5192 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5193 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5194 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5195 now a supported configuration.
5197 * Makefile.in: consolidate image variables into LIBIMAGE; add
5198 W32_OBJ and W32_LIBS. Compile new files.
5201 (_DebPrint) declare tracing facility for W32 debugging. We need
5202 to unify tracing later.
5204 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5205 unconditional use of W32 Unicode functions. Cygwin runs only on
5206 100% Unicode operating systems.
5208 * cygw32.c: New file. Define Cygwin-specific facilities.
5209 (Fcygwin_convert_path_to_windows)
5210 (Fcygwin_convert_path_from_windows): New user functions for
5211 accessing Cygwin path-munging routines.
5213 * cygw32.h: New file.
5214 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5215 UTF-16LE strings temporarily inside non-Lisp-visible string
5218 (w32_strerror): Just what it says on the tin.
5220 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5221 also run for Cygwin; both systems have the same problem with using
5222 GUI facilities in a forked child. Also call syms_of_cygw32,
5223 syms_of_w32select in correct places.
5225 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5226 needs fork-then-exec for daemon launching.
5228 * font.h: Include frame.h.
5230 * image.c: Use the image library cache machinery only when we're
5231 compiling for native WINDOWSNT; Cygwin can use shared libraries
5232 like any other Unixlike system.
5234 * keyboard.c: Clarify a comment regarding the input loop.
5236 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5237 functions directly instead of trying to detect at runtime that our
5238 host operating system supports them. We make this change for two
5239 reasons: Cygwin lacks support for the multibyte character
5240 conversion functions used by the legacy menu code, and Cygwin
5241 never needs to rely on non-Unicode APIs.
5243 * unexw32.c (hinst): Declare extern.
5245 * w32.c: Change header order;
5246 (w32_strerror): Move to w32fns.c because we need it for
5247 non-WINDOWSNT builds.
5249 * w32.h: Add #error macro to make sure we don't include w32.h for
5250 Cygwin builds. Remove w32select declarations.
5252 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5253 w32fns.c. w32console.c is WINDOWSNT-only.
5255 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5256 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5258 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5259 (w32_major_version, w32_minor_version, w32_build_number)
5260 (os_subtype, sound_type): Define here
5261 (w32_defined_color): Make color parameter const for consistency
5262 with other _defined_color functions.
5263 (w32_createwindow): Unconditionally call w32_init_class instead of
5264 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5265 through the code is complex and unnecessary because class
5266 registration is practically free.
5267 (w32_name_of_message): New EMACSDEBUG-only function.
5268 (Fset_message_beep): Move here
5269 (Fx_open_connection): Require that the display name for Windows be
5270 "w32" for consistency, emacsclient disambiguation, and maybe, one
5271 day, multi-window-system support.
5272 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5273 Cygwin files for W32 GUI facilities, since these clearly don't
5274 expect Cygwin names.
5275 (_DebPrint): Define.
5276 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5277 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5278 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5279 (w32_last_error): Remove.
5281 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5283 * w32heap.c (syspage_mask): Declare here.
5284 (cache_system_info): Remove.
5286 * w32inevt.c (faked_key): Define globally, not statically.
5287 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5288 (w32_console_toggle_lock_key): Move to w32fns.c.
5290 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5292 * w32proc.c (_DebPrint): Move to w32fns.c.
5293 * w32select.c: Include string.h, stdio.h for Cygwin.
5294 * w32select.h: New File.
5296 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5298 (w32_message_fd): New variable. Under Cygwin, holds the file
5299 descriptor the system used to tell us about pending thread
5302 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5303 that prevented compilation under non-WINDOWSNT systems.
5305 (w32_initialize): Open /dev/windows and assign it to
5306 w32_message_fd. Provide w32 feature.
5308 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5309 (WM_EMACS_INPUT_READY): add.
5310 (prepend_msg, w32_message_fd): Declare globally.
5313 (keyboard_handle): Use only when WINDOWSNT.
5314 (notify_msg_ready): New function. Posts a message to the main
5315 thread's message queue under CYGWIN, which wakes up the main
5316 thread from select(2) by making the /dev/windows file descriptor
5317 ready. Under WINDOWSNT, it sets an event the same way the old
5320 (post, prepend_msg): Actually call notify_msg_ready instead of
5321 setting the input event directly.
5323 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5325 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5326 but it still has blocs in it, don't return it to the system,
5327 instead of aborting. (Bug#12402)
5329 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5331 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5333 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5334 MAC_OS_X_VERSION_10_6.
5335 (syms_of_nsterm): Remove comment about Panther and above for
5337 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5338 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5339 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5341 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5342 MAC_OS_X_VERSION_10_4.
5344 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5345 MAC_OS_X_VERSION_10_2.
5347 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5349 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5350 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5352 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5353 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5354 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5355 Remove ns_in_resize check.
5356 (ns_clear_frame_area): Remove resize handle code.
5358 * nsfns.m (ns_in_resize): Remove.
5359 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5360 Remove ns_in_resize check.
5362 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5364 Improve sys_siglist detection.
5365 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5366 defined as a macro, as is done in Solaris.
5367 (sys_siglist_entries): New macro.
5368 (save_strsignal): Use it.
5369 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5370 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5372 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5374 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5375 fullscreen/Fullscreen.
5377 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5378 tobar_height is new.
5380 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5381 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5382 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5383 (windowDidResize:): Check for correct window if old style fullscreen.
5384 Capitalize word in comment. Remove incorrect comment.
5385 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5386 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5387 error in drawing background.
5388 (toggleFullScreen:): Remove comment. Rearrange calls.
5389 Set toolbar values to zero, save old height in tobar_height.
5390 Restore tool bar height when leaving fullscreen.
5391 (canBecomeMainWindow): New function.
5393 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5395 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5397 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5399 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5401 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5402 that time stamps of directories could also be changed.
5403 Don't request the too broad GENERIC_WRITE, only the more restrictive
5404 FILE_WRITE_ATTRIBUTES access rights.
5406 * fileio.c (Fset_file_times): Special-case ignoring errors for
5407 directories only on MSDOS, not on MS-Windows.
5409 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5411 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5413 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5415 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5416 see whether CreateFile failed.
5418 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5420 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5421 to avoid similar races.
5422 * keyboard.c (pending_signals): Now bool, not int.
5424 Port timers to OpenBSD, plus check for timer failures.
5425 OpenBSD problem reported by Han Boetes.
5426 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5428 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5429 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5430 like OpenBSD, which has timer_settime but does not declare it.
5431 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5432 whether to use itimerspec-related primitives. All uses of
5433 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5435 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5437 * profiler.c (handle_profiler_signal): Fix a malloc race
5438 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5440 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5442 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5444 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5446 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5447 consistent with the change in return value of 'safe_strsignal'.
5449 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5451 Prefer plain 'static' to 'static inline' (Bug#12541).
5452 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5453 (bidi_set_sor_type, bidi_push_embedding_level)
5454 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5455 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5456 (bidi_cache_search, bidi_cache_ensure_space)
5457 (bidi_cache_iterator_state, bidi_cache_find)
5458 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5459 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5460 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5461 Now 'static', not 'static inline'.
5463 Count overruns when profiling; change units to ns.
5464 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5465 Give extra weight to samples after overruns, to attempt to count
5466 the time more accurately.
5467 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5468 the underlying primitives nominally do ns.
5469 (Fprofiler_cpu_start): Document the change. Mention that
5470 the sampling intervals are only approximate.
5472 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5474 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5476 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5477 case for the special 0 coding-system.
5479 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5480 (Fmake_overlay): Remove redundant tests.
5481 (fix_start_end_in_overlays): Remove redundant recentering.
5483 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5485 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5486 Update dependencies.
5488 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5490 Fix a malloc race condition involving strsignal.
5491 A signal can arrive in the middle of a malloc, and Emacs's signal
5492 handler can invoke strsignal, which can invoke malloc, which is
5493 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5494 Fix it by altering the signal handler so that it does not invoke
5496 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5497 * process.c (status_message): Use const pointer, in case strsignal
5498 is #defined to safe_strsignal.
5499 * sysdep.c (sys_siglist, init_signals): Always define and
5500 initialize a substitute sys_siglist if the system does not define
5501 one, even if HAVE_STRSIGNAL.
5502 (safe_strsignal): Rename from strsignal. Always define,
5503 using sys_siglist. Return a const pointer.
5504 * syssignal.h (safe_strsignal): New decl.
5505 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5507 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5509 * w32proc.c (timer_loop): Fix code that waits for timer
5510 expiration, to avoid high CPU usage.
5512 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5514 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5515 (sweep_weak_table): Remove redundant prototypes.
5517 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5519 * emacs.c: Move the inclusion of TERM_HEADER after including
5520 windows.h on WINDOWSNT. This avoids compilation problems with
5523 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5525 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5526 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5527 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5528 as the previous version used 'void *'.
5530 * ralloc.c (ROUNDUP): Fix last change.
5531 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5534 * w32proc.c <disable_itimers>: New static flag.
5535 (init_timers): Initialize it to zero, after creating the critical
5536 sections used by the timer threads.
5537 (term_timers): Set to 1 before deleting the critical sections.
5538 (getitimer, setitimer): If disable_itimers is non-zero, return an
5539 error indication without doing anything. Reported by Fabrice
5540 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5541 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5543 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5546 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5547 term_ntproc after all the other bookkeeping, to get timers working
5548 as long as possible.
5550 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5552 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.

5556 Prefer plain 'static' to 'static inline' (Bug#12541).
5557 With static functions, modern compilers inline pretty well by
5558 themselves; advice from programmers often hurts as much as it helps.
5559 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5560 this change shrinks the text size of the Emacs executable by 1.1%
5561 without affecting CPU significantly in my benchmark.

5860 for consistency with other handlers.
5861 (setup_cpu_timer): New function, with much of what used to be in

5867 (Fprofiler_cpu_start): Use it.
5868 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5869 Don't assume that passing NULL as the 2nd argument of setitimer

5872 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5873 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in

5993 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
5994 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
5995 (Fdump_emacs): Reset Vlibrary_cache and image_types.
5997 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
5998 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
6000 * w32.h (Vlibrary_cache): Do not declare.
6002 2012-09-25 Eli Zaretskii <eliz@gnu.org>
6004 * w32proc.c (sys_signal): Handle all signals defined by the
6005 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6006 handlers for signals supported by Windows. Don't override
6007 term_ntproc as the handler for SIGABRT.
6008 (sigaction): Rewrite to call sys_signal instead of duplicating its
6010 (sys_kill): Improve commentary.
6012 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6013 consistency with a signature of a signal handler. All callers
6015 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6016 install term_ntproc as a signal handler for SIGABRT, as that
6017 should be done by the dumped Emacs.
6019 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6021 * w32select.c (term_w32select): Protect against repeated
6022 invocation by setting clipboard_owner to NULL after calling
6025 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
6026 and term_ntproc to their modified signatures.
6028 * character.c (char_string, string_char): Remove calls to
6029 MAYBE_UNIFY_CHAR. See the discussion starting at
6030 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
6033 2012-09-25 Chong Yidong <cyd@gnu.org>
6035 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
6037 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6039 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6040 when encountering an unknown bytecode.
6042 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6044 image.c, indent.c: Use bool for booleans.
6045 * dispextern.h (struct image_type): Members valid_p, load, init
6046 now return bool, not int. All uses changed.
6047 * image.c: Omit unnecessary static decls.
6048 (x_create_bitmap_mask, x_build_heuristic_mask):
6049 Return void, not int, since callers don't care about the return value.

6078 Use bool for booleans.
6080 2012-09-24 Chong Yidong <cyd@gnu.org>
6082 * chartab.c (Fset_char_table_default): Obsolete function removed.
6084 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6086 Move pid_t related decls out of lisp.h.
6087 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6088 (interruptible_wait_for_termination):
6089 Move these decls from lisp.h to syswait.h, since they use pid_t.
6090 Needed on FreeBSD; see Herbert J. Skuhra in
6091 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6092 * callproc.c: Include syswait.h.

6109 * nsmenu.m (ns_update_menubar):
6110 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
6111 * xfns.c (Fx_show_tip) [USE_GTK]:
6112 Use bool for boolean.
6113 * gtkutil.c (xg_update_frame_menubar):
6114 * xmenu.c (update_frame_menubar):
6115 Return void, not int, since caller ignores return value.
6116 * gtkutil.c (xg_change_toolbar_position):
6119 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6121 * makefile.w32-in (BLOCKINPUT_H): Remove.

6138 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6140 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6141 fatal_error_backtrace.
6143 * w32proc.c (sys_kill): Undo last change: don't do anything when
6144 invoked to deliver SIGABRT to our own process. This is now
6145 handled by emacs_raise.
6147 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6149 * w32term.c (w32_read_socket): Remove leftover reference to
6150 interrupt_input_pending.
6152 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6154 Do not use SA_NODEFER.
6155 Problem reported by Dani Moncayo in
6156 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6158 * sysdep.c (emacs_abort): Do not reset signal handler.
6159 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6160 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6161 wanted even on POSIXish hosts, and it doesn't work on Windows.
6163 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6165 * xterm.c (x_term_init): Call fixup_locale before and after calling
6166 gtk_init (Bug#12392).
6168 2012-09-23 Chong Yidong <cyd@gnu.org>
6170 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6171 Vdynamic_library_alist.
6173 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6174 (Fgnutls_available_p): Caller changed.
6176 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6177 (Flibxml_parse_xml_region): Likewise.
6179 * dispextern.h (struct image_type): Remove arg from init function.
6181 * image.c (Finit_image_library, lookup_image_type)
6182 (define_image_type): Remove now-unneeded second arg.
6183 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6184 (init_tiff_functions, init_gif_functions, init_svg_functions):
6185 Arglist and w32_delayed_load calling convention changed.
6186 (gs_type): Remove init_gs_functions; there is no such function.
6187 (valid_image_p, make_image): Fix caller to lookup_image_type.
6189 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6191 Simplify and avoid signal-handling races (Bug#12471).
6193 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6194 Avoid recursive loop if there's a fatal error in the function itself.
6195 * atimer.c (pending_atimers):
6196 * blockinput.h: Don't include "atimer.h"; no longer needed.
6197 (interrupt_input_pending): Remove. All uses removed.
6198 pending_signals now counts both atimers and ordinary interrupts.
6199 This is less racy than having three separate pending-signal flags.
6200 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6202 Rename from their upper-case counterparts BLOCK_INPUT,
6203 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6204 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6205 This makes it easier to access volatile variables more accurately.
6206 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6207 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6208 that's more reliable if the code is buggy and sets
6209 interrupt_input_blocked to a negative value. All uses changed.
6210 * atimer.c (deliver_alarm_signal):
6211 Remove. No need to deliver this to the parent; any thread can
6212 handle this signal now. All uses replaced by underlying handler.
6213 * atimer.c (turn_on_atimers):
6214 * dispnew.c (handle_window_change_signal):
6215 * emacs.c (handle_danger_signal):
6216 * keyboard.c (kbd_buffer_get_event):
6217 Don't reestablish signal handler; not needed with sigaction.
6218 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6220 Rework to avoid unnecessary accesses to volatile variables.
6221 (UNBLOCK_INPUT_TO): Now a function.
6222 (totally_unblock_input, unblock_input): New decls.
6223 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6224 (init_data): Remove. Necessary stuff now done in init_signal.
6225 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6226 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6227 (fatal_error_code): Remove; no longer needed.
6228 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6229 it doesn't always backtrace. All uses changed. No need to reset
6230 signal to default, since sigaction and/or die does that for us now.
6231 Use emacs_raise (FOO), not kill (getpid (), FOO).
6232 (main): Check more-accurately whether we're dumping.
6233 Move fatal-error setup to sysdep.c
6234 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6235 * gtkutil.c (xg_get_file_name, xg_get_font):
6236 Remove no-longer-needed signal-mask manipulation.
6237 * keyboard.c, process.c (POLL_FOR_INPUT):
6238 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6239 * keyboard.c (read_avail_input): Remove.
6240 All uses replaced by gobble_input.
6241 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6242 (kbd_buffer_store_event_hold, gobble_input):
6243 (record_asynch_buffer_change) [USABLE_SIGIO]:
6244 (store_user_signal_events):
6245 No need to mess with signal mask.
6246 (gobble_input): If blocking input and there are terminals, simply
6247 set pending_signals to 1 and return. All hooks changed to not
6248 worry about whether input is blocked.
6249 (process_pending_signals): Clear pending_signals before processing
6250 them, in case a signal comes in while we're processing.
6251 By convention callers now test pending_signals before calling us.
6252 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6253 New functions, to support changes to blockinput.h.
6254 (handle_input_available_signal): Now extern.
6255 (reinvoke_input_signal): Remove. All uses replaced by
6257 (quit_count): Now volatile, since a signal handler uses it.
6258 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6259 All callers changed. Block SIGINT only if not already blocked.
6260 Clear sigmask reliably, even if Fsignal returns, which it can.
6261 Omit unnecessary accesses to volatile var.
6262 (quit_throw_to_read_char): No need to restore sigmask.
6263 * keyboard.c (gobble_input, handle_user_signal):
6264 * process.c (wait_reading_process_output):
6265 Call signal-handling code rather than killing ourselves.
6266 * lisp.h: Include <float.h>, for...
6267 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6268 (pending_signals): Now volatile.
6269 (syms_of_data): Now const if IEEE floating point.
6270 (handle_input_available_signal) [USABLE_SIGIO]:
6271 (terminate_due_to_signal, record_child_status_change): New decls.
6272 * process.c (create_process): Avoid disaster if memory is exhausted
6273 while we're processing a vfork, by tightening the critical section
6275 (send_process_frame, process_sent_to, handle_pipe_signal)
6276 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6278 (send_process): No need for setjmp/longjmp any more, since the
6279 SIGPIPE stuff is now gone. Instead, report an error if errno
6281 (record_child_status_change): Now extern. PID and W are now args.
6282 Return void, not bool. All callers changed.
6283 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6284 Remove. All uses removed. This bug should be fixed now in a
6286 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6287 and record the child status change directly. This avoids the
6288 need to futz with the signal mask.
6289 (process_fatal_action): Move here from emacs.c.
6290 (emacs_sigaction_flags): New function, containing
6291 much of what used to be in emacs_sigaction_init.
6292 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6293 caught by emacs, to make races less likely.
6294 (deliver_process_signal): Rename from handle_on_main_thread.
6296 (BACKTRACE_LIMIT_MAX): Now at top level.
6297 (thread_backtrace_buffer, threadback_backtrace_pointers):
6299 (deliver_thread_signal, deliver_fatal_thread_signal):
6300 New functions, for more-accurate delivery of thread-specific signals.
6301 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6302 (deliver_arith_signal): Handle in this thread, not
6303 in the main thread, since it's triggered by this thread.
6304 (maybe_fatal_sig): New function.
6305 (init_signals): New arg DUMPING so that we can be more accurate
6306 about whether we're dumping. Caller changed.
6307 Treat thread-specific signals differently from process-general signals.
6308 Block all signals while handling fatal error; that's safer.
6309 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6311 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6312 Ignore SIGPIPE unless batch.
6313 (emacs_backtrace): Output backtrace for the appropriate thread,
6314 which is not necessarily the main thread.
6315 * syssignal.h: Include <stdbool.h>.
6316 (emacs_raise): New macro.
6317 * xterm.c (x_connection_signal): Remove; no longer needed
6318 now that we use sigaction.
6319 (x_connection_closed): No need to mess with sigmask now.
6320 (x_initialize): No need to reset SIGPIPE handler here, since
6321 init_signals does this for us now.
6323 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6325 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6326 background rect may be larger (Bug#12245).
6328 2012-09-23 Chong Yidong <cyd@gnu.org>
6330 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6332 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6334 * .gdbinit: Just stop at fatal_error_backtrace.
6335 See Stefan Monnier's request in
6336 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6337 Remove no-longer-used query of system type.
6339 2012-09-22 Chong Yidong <cyd@gnu.org>
6341 * search.c (Freplace_match): Doc fix (Bug#12325).
6343 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6345 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6346 (Fline_end_position): Doc fix.
6348 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6350 2012-09-22 Chong Yidong <cyd@gnu.org>
6352 * dispextern.h (struct image_type): Add new slot, storing a type
6353 initialization function.
6355 * image.c (define_image_type): Call the image initializer function
6356 if it is defined. Arguments and return value changed.
6357 (valid_image_p, make_image): Callers changed.
6358 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6359 (gif_type, imagemagick_type, svg_type, gs_type):
6360 Add initialization functions.
6361 (Finit_image_library): Call lookup_image_type.
6362 (CHECK_LIB_AVAILABLE): Macro deleted.
6363 (lookup_image_type): Call define_image_type here, rather than via
6364 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6365 (syms_of_image): Move define_image_type calls for xbm_type and
6366 pbm_type to lookup_image_type.
6368 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6370 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6371 'idle_timers' from here ...
6372 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6373 lists, to avoid infloops when the timer does something stupid,
6374 like reinvoke itself with the same or smaller time-out.
6377 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6379 * window.c (Fsplit_window_internal): Handle only Qt value of
6380 Vwindow_combination_limit separately.
6381 (Qtemp_buffer_resize): New symbol.
6382 (Vwindow_combination_limit): New default value.
6385 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6387 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6388 the new overlay string. (Bug#10159)
6390 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6392 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6393 or that fprintf is async-signal-safe. POSIX doesn't require
6396 2012-09-22 Chong Yidong <cyd@gnu.org>
6398 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6401 2012-09-22 Kenichi Handa <handa@gnu.org>
6403 * composite.c (composition_reseat_it): Handle the case that a
6404 grapheme cluster is not covered by a single font (Bug#12352).
6406 2012-09-21 Chong Yidong <cyd@gnu.org>
6408 * image.c (define_image_type): Avoid adding duplicate types to
6409 image_types (Bug#12463). Suggested by Jörg Walter.
6411 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6413 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6414 (print_load_command_name): Add case LC_DATA_IN_CODE.
6415 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6417 2012-09-21 Glenn Morris <rgm@gnu.org>
6419 * eval.c (Frun_hook_with_args_until_success)
6420 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6422 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6424 * fileio.c (Ffile_selinux_context): Only call freecon when
6425 lgetfilecon succeeded.
6426 (Fset_file_selinux_context): Likewise. (Bug#12444)
6428 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6430 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6431 reordering, locate the cursor by calling set_cursor_from_row; if
6432 that fails, clear the desired glyph matrix before returning a
6433 failure indication to the caller. Fixes leaving garbled display
6434 when fast scrolling with a down-key. (Bug#12403)
6435 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6436 scrolling through multibyte text.
6438 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6440 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6441 calling mark_vectorlike since that's the one that marks the window.
6442 (mark_discard_killed_buffers): Mark the final cdr.
6443 * window.h (struct window): Move prev/next_buffers to the
6444 non-standard fields.
6445 * window.c (make_window): Initialize prev/next_buffers manually.
6447 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6449 Omit unused arg EXPECTED from socket hooks.
6450 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6451 * nsterm.m (ns_term_init):
6452 * termhooks.h (struct terminal.read_socket_hook):
6453 * w32inevt.c (w32_console_read_socket):
6454 * w32term.c (w32_read_socket):
6455 * xterm.c (XTread_socket):
6456 Omit unused arg EXPECTED. All callers changed.
6457 (store_user_signal_events): Return void, not int, since callers no
6458 longer care about the return value. All uses changed.
6460 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6462 * w32gui.h (XParseGeometry): Do not declare.
6464 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6466 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6467 Ignore 'expected'. See Eli Zaretskii in
6468 <http://bugs.gnu.org/12471#8> (last line).
6470 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6471 (XParseGeometry): Now static. Substitute extremal values for
6472 values that are out of range.
6474 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6476 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6478 * nsfns.m (XParseGeometry): Remove.
6479 (Fx_create_frame): Call x_set_offset to correctly interpret
6480 top_pos in geometry.
6482 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6483 (Fx_parse_geometry): If there is a space in string, call
6484 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6486 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6488 * search.c (scan_buffer): Use character positions in calls to
6489 region_cache_forward and region_cache_backward, not byte
6490 positions. (Bug#12196)
6492 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6493 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6495 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6496 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6497 emacs_blocked_malloc, now deleted.
6499 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6501 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6502 The workaround was for improving performance on Solaris 2.4, but
6503 is getting in the way now. Emacs will still work if someone is
6504 still running Solaris 2.4 in a museum somewhere; Sun dropped
6505 support for Solaris 2.4 in 2003.
6506 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6507 * process.c (create_process) [HAVE_WORKING_VFORK]:
6508 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6509 since Emacs no longer uses vfork on that platform.
6511 2012-09-17 Glenn Morris <rgm@gnu.org>
6513 * emacs.c: Use COPYRIGHT.
6515 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6517 Remove configure's --without-sync-input option (Bug#12450).
6518 When auditing signal-handling in preparation for cleaning it up,
6519 I found that SYNC_INPUT has race conditions and would be a real
6520 pain to fix. Since it's an undocumented and deprecated
6521 configure-time option, now seems like a good time to remove it.
6522 Also see <http://bugs.gnu.org/11080#16>.
6523 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6524 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6525 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6526 (malloc_hysteresis):
6527 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6528 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6529 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6530 (dont_register_blocks, bytes_used_when_reconsidered)
6531 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6532 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6533 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6534 Remove. All uses removed.
6535 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6536 implementation, one that depends on whether the new macro
6537 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6539 * atimer.c (run_timers, handle_alarm_signal):
6540 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6541 (handle_async_input, process_pending_signals)
6542 (handle_input_available_signal, init_keyboard):
6543 * nsterm.m (ns_read_socket):
6544 * process.c (wait_reading_process_output):
6545 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6546 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6548 * xterm.c (XTread_socket):
6550 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6551 * eval.c (handling_signal): Remove. All uses removed.
6552 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6553 All uses replaced with the SYNC_INPUT version.
6554 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6556 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6559 * font.c (Ffont_shape_gstring): Remove unused local.
6561 2012-09-16 Glenn Morris <rgm@gnu.org>
6563 * Makefile.in (clean): No longer run nextstep's clean.
6565 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6567 (ns-app): Move here from ns.mk, and simplify.
6568 (clean): Simplify nextstep entry.
6569 * ns.mk: Remove file.
6571 2012-09-17 Kenichi Handa <handa@gnu.org>
6573 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6574 not covert the last few charactes.
6576 2012-09-16 Kenichi Handa <handa@gnu.org>
6578 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6579 here, but just check the validity of glyphs in the glyph-string.
6581 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6583 * window.c (Fwindow_parameter, Fset_window_parameter):
6584 Accept any window as argument (Bug#12452).
6586 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6588 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6589 to ns_term_init to avoid memory leak.
6591 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6592 explicit retain/release.
6593 (ns_term_init): Only allow one display. Initialize outerpool and
6596 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6598 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6599 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6600 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6601 the Microsoft problem in a different way, by altering ../nt/config.nt.
6603 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6618 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6619 by lisp.h. This completes removal of setjmp.h inclusion
6620 erroneously announced in the previous commit. (Bug#12446)
6622 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6625 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6626 not defined as a macro. The latter happens on MS-Windows.
6629 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6631 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6632 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6633 Some instances of '#include <setjmp.h>' removed, if the
6634 only reason for the instance was because "lisp.h" was included.
6635 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6636 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6637 and _longjmp with the new symbols. Emacs already uses _setjmp if
6638 available, so this change affects only POSIXish hosts that have
6639 sigsetjmp but not _setjmp, such as some versions of Solaris and
6640 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6641 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6642 (png_load_body) [HAVE_PNG]:
6643 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6644 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6645 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6646 since PNG requires jmp_buf. This is the only exception to the
6647 general rule that we now use sys_setjmp and sys_longjmp.
6648 This exception is OK since this code does not change the signal
6649 mask or longjmp out of a signal handler.
6651 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6653 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6654 Include "syssignal.h", for 'main_thread'.
6656 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6658 Avoid out-of-range marker position (Bug#12426).
6659 * insdel.c (replace_range, replace_range_2):
6660 Adjust markers before overlays, as suggested by comments.
6661 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6662 Remove redundant check before calling offset_intervals.
6664 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6666 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6667 current buffer (Bug#12387).
6669 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6671 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6673 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6675 Use a more backwards-compatible timer format (Bug#12430).
6676 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6677 vector element, not from the 4th, since PSECS is now at the end.
6678 (Fcurrent_idle_time): Doc fix.
6680 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6682 Function to mark objects and remove killed buffers at once.
6683 * alloc.c (discard_killed_buffers): Rename to ...
6684 (mark_discard_killed buffers) ... new name. Add marking
6685 of remaining objects. Fix comment. Adjust users.
6686 (mark_object): Do not touch frame buffer lists here.
6687 * frame.c (delete_frame): Reset frame buffer lists here.
6689 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6691 Better workaround for GNOME bug when --enable-gcc-warnings.
6692 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6693 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6694 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6696 Simplify SIGIO usage (Bug#12408).
6697 The code that dealt with SIGIO was crufty and confusing, e.g., it
6698 played tricks like "#undef SIGIO" but these tricks were not used
6699 consistently. Simplify mostly by not #undeffing standard symbols,
6700 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6701 or not as we please) rather than "defined SIGIO" (standard symbol
6702 that we probably shouldn't #undef).
6703 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6704 Modules that need it can include it.
6705 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6706 * dispextern.h (ignore_sigio): New decl.
6707 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6708 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6709 * emacs.c (shut_down_emacs):
6710 * keyboard.c (kbd_buffer_store_event_hold):
6711 Use ignore_sigio rather than invoking 'signal' directly.
6712 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6714 (FIONREAD, SIGIO): Do not #undef.
6715 (tty_read_avail_input): Use #error rather than a syntax error.
6716 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6717 for I_PIPE, used by SETUP_SLAVE_PTY.
6718 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6719 * sysdep.c (croak): Remove; no longer needed. This bit of
6720 temporary code, with Fred N. Fish's comment that it's temporary,
6721 has been in Emacs since at least 1992!
6722 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6723 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6724 * syssignal.h (croak): Remove decl.
6725 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6726 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6727 now that we're termios-only.
6728 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6729 * term.c (dissociate_if_controlling_tty): Use #error rather than
6732 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6733 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6734 to work around GNOME bug 683906.
6735 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6736 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6737 This works around GCC bug 54561.
6739 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6741 More fixes for 'volatile' and setjmp/longjmp.
6742 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6743 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6744 (png_load_body) [HAVE_PNG]:
6745 (jpeg_load_body) [HAVE_JPEG]:
6746 New function, with most of the old parent function's body.
6747 (png_load) [HAVE_PNG]:
6748 (jpeg_load) [HAVE_JPEG]:
6749 Invoke the new function, to avoid longjmp munging our locals.
6750 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6751 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6752 longjmp is passed 2, as the C standard doesn't guarantee this.
6753 Instead, store the failure code into mgr->failure_code.
6755 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6757 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6758 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6759 (syms_of_keyboard): Remove support for unread-command-char.
6761 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6763 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6764 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6765 violation. (Bug#12426)
6767 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6769 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6771 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6773 * eval.c: Add `inhibit-debugger'.
6774 (Qinhibit_debugger): New symbol.
6775 (call_debugger): Bind it instead of Qdebug_on_error.
6776 (maybe_call_debugger): Test Vinhibit_debugger.
6777 (syms_of_eval): Define inhibit-debugger.
6778 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6779 (syms_of_xdisp): Remove inhibit-debug-on-message.
6781 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6783 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6784 If a nonvolatile local variable is written before a _longjmp to
6785 the frame containing the variable, and is read after the _longjmp,
6786 the value read is indeterminate. Some local variables of type
6787 'struct handler' and 'struct catchtag' are used in this way, so
6788 mark each of their slots as volatile if the slot can be set before
6789 _longjmp and read afterwards.
6790 * lisp.h (struct handler): var and chosen_clause are now volatile.
6791 (struct catchtag): val, next, and pdlcount are now volatile.
6793 * bidi.c (bidi_push_it, bidi_pop_it):
6794 * fns.c (copy_hash_table):
6795 * image.c (define_image_type):
6796 * keyboard.c (kbd_buffer_store_event_hold):
6797 * process.c (Fprocess_send_eof):
6798 * xfaces.c (x_create_gc) [HAVE_NS]:
6799 * xgselect.c (xg_select):
6800 Prefer assignment to memcpy when either will do.
6802 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6803 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6804 time an item is removed. No need to mark this function 'inline';
6805 the compiler knows better than we do.
6807 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6809 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6810 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6811 to change_frame_size (Bug#12388).
6812 (windowDidResize:): Pass YES to updateFrameSize.
6814 * nsterm.h: Add delay parameter to updateFrameSize.
6816 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6818 Discard killed buffers from deleted window and frame objects.
6819 This reduces an amount of references to killed buffers and
6820 helps GC to reclaim them faster.
6821 * alloc.c (discard_killed_buffers): New function.
6822 (mark_object): Use it for deleted windows and frames.
6823 (mark_object): If symbol's value is set up for a killed buffer
6824 or deleted frame, restore its global binding.
6825 * data.c (swap_in_global_binding): Add GC notice.
6826 (swap_in_symval_forwarding): Use convenient set_blv_where.
6827 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6828 * window.h: ... to here.
6830 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6832 Convenient macro to check whether the buffer is live.
6833 * buffer.h (BUFFER_LIVE_P): New macro.
6834 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6835 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6837 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6839 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6840 composition cases (Bug#12364).
6842 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6843 overhang of succeeding glyphs overlapping box cursor.
6845 * w32term.c (x_draw_glyph_string): Likewise.
6847 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6849 Simplify, document, and port floating-point (Bug#12381).
6850 The porting part of this patch fixes bugs on non-IEEE platforms
6851 with frexp, ldexp, logb.
6852 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6854 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6855 support, by removing commented-out code and briefly listing the
6856 C89 functions excluded. The commented-out stuff was confusing
6857 maintenance, e.g., we thought we needed cbrt but it was commented out.
6858 (logb): Remove decl; no longer needed.
6859 (isfinite): New macro, if not already supplied.
6860 (isnan): Don't replace any existing macro.
6861 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6862 are present on all C89 platforms.
6863 (Ffrexp): Do not special-case zero, as frexp does the right thing
6865 (Flogb): Do not use logb, as it doesn't have the desired meaning
6866 on hosts that use non-base-2 floating point. Instead, stick with
6867 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6868 frexp, to avoid getting an unspecified result.
6870 * xdisp.c (Qinhibit_debug_on_message): Now static.
6872 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6874 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6875 NSBezierPath (Bug#12131).
6877 2012-09-10 Chong Yidong <cyd@gnu.org>
6879 * fns.c (Fdelq, Fdelete): Doc fix.
6881 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6883 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6884 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6886 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6888 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6889 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6892 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6894 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6895 left fringe if the window has a left margin. This avoids leaving
6896 traces of the cursor because its leftmost pixel is not drawn over.
6898 * dispnew.c (update_window_line): When the left margin area of a
6899 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6900 that screen line. (Bug#12277)
6902 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6904 Assume C89 or later for math functions (Bug#12381).
6905 This simplifies the code, and makes it a bit smaller and faster,
6906 and (most important) makes it easier to clean up signal handling
6907 since we can stop worring about floating-point exceptions in
6908 library code. That was a problem before C89, but the problem
6909 went away many years ago on all practical Emacs targets.
6910 * data.c, image.c, lread.c, print.c:
6911 Don't include <math.h>; no longer needed.
6912 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6913 might be autoconfigured, as that never happens.
6915 * doprnt.c (DBL_MAX_10_EXP):
6916 * print.c (DBL_DIG):
6917 Remove. C89 or later always defines these.
6918 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6919 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6920 (arith_error, domain_error, domain_error2):
6921 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6922 no longer needed -- we simply return what C returns. All uses removed.
6923 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6925 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6926 Remove. All uses expanded, as these macros are no longer used
6927 more than once and are now more trouble than they're worth.
6928 (Ftan): Use tan, not sin / cos.
6929 (Flogb): Assume C89 frexp.
6930 (fmod_float): Assume C89 fmod.
6931 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6932 (init_floatfns): Remove. All uses removed.
6934 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6936 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6937 compositeToPoint for OSX < 10.6 (Bug#12390).
6939 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6941 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6942 This produces more-accurate results.
6944 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6946 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6947 changes (Bug#12088).
6949 2012-09-08 Chong Yidong <cyd@gnu.org>
6951 * syntax.c (Fstring_to_syntax): Doc fix.
6953 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6955 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6956 in the internal border.
6957 (x_set_window_size): Remove static variables and their usage.
6958 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6959 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6960 Remove fringe/internal border adjustment (Bug#11052).
6961 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6962 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6963 (ns_fix_rect_ibw): Remove.
6964 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6965 (ns_dumpglyphs_box_or_relief): Ditto.
6966 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6968 (ns_dumpglyphs_image): Ditto.
6969 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6971 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6972 their usage. Add fringe_extended_p and its use as in other terms.
6973 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6974 scroll bar was removed.
6975 (updateFrameSize): New function.
6976 (windowDidResize): Move code to updateFrameSize and call it.
6978 * nsterm.h (EmacsView): Add updateFrameSize.
6980 2012-09-07 Chong Yidong <cyd@gnu.org>
6982 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6984 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6986 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6988 More signal-handler cleanup (Bug#12327).
6989 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6990 Problem introduced when merging patches. Noted by Eli Zaretskii in
6991 <http://bugs.gnu.org/12327#67>.
6992 * floatfns.c: Comment fix.
6993 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6994 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6995 and anyway the declaration is harmless even if SIGDANGER is not defined.
6996 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6997 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6998 source files not surprisingly expected syssignal.h to define, or
6999 not define, SIGIO, and it's cleaner to do it that way, for consistency.
7000 Include <sys/ioctl.h>, for FIONREAD.
7001 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
7002 This eliminates a problem whereby other files mysteriously had
7003 to include "syssignal.h" before including "systty.h" if they
7004 wanted to use "#ifdef SIGIO".
7006 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7008 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7010 * w32.c (sigemptyset): Empty the set.
7011 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7013 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7015 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7017 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7018 (mark_object): Likewise for frame objects.
7020 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7022 * syssignal.h (handle_on_main_thread): Always declare,
7023 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7024 This ports to platforms without HAVE_PTHREAD.
7026 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7028 Signal-handler cleanup (Bug#12327).
7029 Emacs's signal handlers were written in the old 4.2BSD style with
7030 sigblock and sigmask and so forth, and this led to some
7031 inefficiencies and confusion. Rewrite these to use
7032 pthread_sigmask etc. without copying signal sets around. Also,
7033 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7034 'signal', and instead use functions that do not attempt to take
7035 over the system name space. This patch causes Emacs's text
7036 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7037 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7038 Do not include <signal.h> or "syssignal.h", as these
7039 modules do not use signals.
7040 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7041 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7042 Do not include <signal.h>, as "syssignal.h" does that for us now.
7043 * atimer.c (sigmask_atimers): New function.
7044 (block_atimers, unblock_atimers): New functions,
7045 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7047 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7048 no longer needed here.
7049 * emacs.c (main): Inspect existing signal handler with sigaction,
7050 so that there's no need to block and unblock SIGHUP.
7051 * sysdep.c (struct save_signal): New member 'action', replacing
7052 old member 'handler'.
7053 (save_signal_handlers, restore_signal_handlers):
7054 Use sigaction instead of 'signal' to save and restore.
7055 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7056 New function. All users of 'signal' modified to use set_sighandler
7057 if they're writeonly, and to use sys_signal if they're read+write.
7058 (emacs_sigaction_init, forwarded_signal): New functions.
7059 (sys_signal): Remove. All uses replaced by calls to sigaction
7060 and emacs_sigaction_init, or by direct calls to 'signal'.
7061 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7062 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7063 all uses replaced by pthread_sigmask etc. calls.
7064 * syssignal.h: Include <signal.h>.
7065 (emacs_sigaction_init, forwarded_signal): New decls.
7066 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7067 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7068 (sigmask, sys_sigmask): Remove; no longer needed.
7069 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7070 (sigblock, sigunblock, sigfree):
7071 (sigsetmask) [!defined sigsetmask]:
7072 Remove. All uses replaced by pthread_sigmask.
7073 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7074 no longer need to be replaced, and its typical old uses
7075 are now done via emacs_sigaction_init and sigaction.
7076 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7077 (sys_sigdel): Remove; unused.
7078 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7080 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7082 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7083 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7085 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7087 Explicitly mark buffer_defaults and buffer_local_symbols.
7088 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7089 mark_local_symbols here.
7090 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7091 since special buffers aren't marked here any more.
7092 (allocate_buffer): Chain new buffer with all_buffers here...
7093 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7095 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7096 (syms_of_buffer): Remove staticpro of the above.
7097 (init_buffer_once): Set names for buffer_defaults and
7098 buffer_local_symbols.
7100 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7102 Use bool for booleans in font-related modules.
7103 * font.c (font_intern_prop, font_style_to_value)
7104 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7105 (generate_otf_features, font_check_otf_features, font_check_otf)
7106 (font_match_p, font_list_entities, font_at):
7107 * fontset.c (fontset_id_valid_p, reorder_font_vector
7108 (fontset_find_font, Fset_fontset_font)
7109 (face_suitable_for_char_p) [0]:
7110 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7111 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7112 (m17n_flt_initialized, ftfont_shape_by_flt):
7113 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7114 * nsfont.m (nsfont_draw):
7115 * w32font.c (w32font_draw):
7116 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7117 Use bool for booleans.
7118 * font.h: Adjust to above API changes.
7119 (struct font, struct font_driver, struct font_driver_list):
7120 Use bool for booleans.
7121 (struct font): Remove useless member encoding_type.
7123 * fontset.c, xftfont.c: Omit unnecessary static decls.
7125 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7127 * alloc.c (mark_object): Revert window marking code
7128 since it's unsafe for the Fset_window_configuration.
7130 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7132 Fix race conditions with signal handlers and errno (Bug#12327).
7133 Be more systematic about preserving errno whenever a signal
7134 handler returns, even if it's not in the main thread. Do this by
7135 renaming signal handlers to distinguish between signal delivery
7136 and signal handling. All uses changed.
7137 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7138 * data.c (deliver_arith_signal): Rename from arith_error.
7139 * dispnew.c (deliver_window_change_signal): Rename from
7140 window_change_signal.
7141 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7142 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7143 * keyboard.c (deliver_input_available_signal): Rename from
7144 input_available_signal.
7145 (deliver_user_signal): Rename from handle_user_signal.
7146 (deliver_interrupt_signal): Rename from interrupt_signal.
7147 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7148 (deliver_child_signal): Rename from sigchld_handler.
7149 * atimer.c (handle_alarm_signal):
7150 * data.c (handle_arith_signal):
7151 * dispnew.c (handle_window_change_signal):
7152 * emacs.c (handle_fatal_signal, handle_danger_signal):
7153 * keyboard.c (handle_input_available_signal):
7154 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7155 * process.c (handle_pipe_signal, handle_child_signal):
7156 New functions, with the actual signal-handling code taken from the
7157 original respective signal handlers, sans the sporadic attempts to
7158 preserve errno, since that's now done by handle_on_main_thread.
7159 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7160 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7161 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7163 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7164 Move initialization of main_thread to sysdep.c's init_signals.
7165 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7166 our usage, and simplifies the mainline code.
7167 (record_child_status_change): New static function, as a helper
7168 for handle_child_signal, and with most of the old child handler's
7170 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7171 (handle_child_signal): Use the above.
7172 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7173 Moved here from emacs.c.
7174 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7175 code moved here from emacs.c's main function.
7176 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7177 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7178 This lets callers save and restore errno properly.
7180 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7182 Remove redundant or unused things here and there.
7183 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7184 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7185 * editfns.c (Fcompare_buffer_substrings): Likewise.
7186 * frame.h (struct terminal, struct font_driver_list):
7187 Remove redundant declarations.
7188 * window.h (Qleft, Qright): Likewise.
7190 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7192 Do not mark objects from deleted buffers, windows and frames.
7193 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7194 (mark_object): Likewise for windows and frames.
7196 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7198 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7199 buffer_defaults and buffer_local_symbols as valid objects.
7200 Return special value to denote them.
7202 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7204 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7205 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7206 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7207 (file_name_absolute_p, Fsubstitute_in_file_name):
7208 (check_executable, check_writable, Ffile_accessible_directory_p)
7209 (Fset_file_selinux_context, Fdefault_file_modes)
7210 (Finsert_file_contents, choose_write_coding_system)
7211 (Fwrite_region, build_annotations, a_write, e_write)
7213 * filelock.c (boot_time_initialized, get_boot_time)
7214 (get_boot_time_1, lock_file_1, within_one_second):
7215 * floatfns.c (in_float):
7216 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7217 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7218 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7219 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7220 * window.c (compare_window_configurations):
7221 Use bool for booleans.
7222 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7223 (Fdefault_file_modes): Now mode_t, not int, for modes.
7224 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7225 (internal_delete_file): Now returns void, not a (boolean) int,
7226 since nobody was looking at the return value.
7227 * lisp.h, window.h: Adjust to above API changes.
7229 * xdisp.c (set_message): Simplify and reindent last change.
7231 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7233 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7235 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7237 * eval.c (call_debugger): Make the function non-static so that we
7238 can call it from set_message.
7240 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7241 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7243 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7245 Give more-useful info on a fatal error (Bug#12328).
7246 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7247 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7248 of doing the work ourselves.
7249 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7250 do most of the work.
7251 (fatal_error_backtrace): New function, taken from the guts
7252 of the old fatal_error_signal, but with a new option to output
7254 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7255 info about the signal than just its number.
7256 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7257 * sysdep.c: Include <execinfo.h>
7258 (emacs_backtrace): New function, taken partly from the previous
7259 code of the 'die' function.
7260 (emacs_abort): Call fatal_error_backtrace rather than abort.
7262 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7264 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7265 eager (load-time) macro-expansion.
7266 * lisp.mk (lisp): Add macroexp.
7268 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7270 Simplify redefinition of 'abort' (Bug#12316).
7271 Do not try to redefine the 'abort' function. Instead, redo
7272 the code so that it calls 'emacs_abort' rather than 'abort'.
7273 This removes the need for the NO_ABORT configure-time macro
7274 and makes it easier to change the abort code to do a backtrace.
7275 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7276 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7277 Remove; sysdep.c's emacs_abort now takes its place.
7278 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7279 'abort' changed to use 'emacs_abort'.
7280 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7281 (abort) [!defined abort]: Rename to ...
7282 (emacs_abort): ... new name.
7283 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7284 the place of the old 'abort' in emacs.c.
7285 * w32.c, w32fns.c (abort): Do not #undef.
7286 * w32.c (emacs_abort): Rename from w32_abort.
7288 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7290 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7291 offsets[j].dv, since the y axis of the screen coordinates points
7292 down, while the y axis of the font definition coordinates points
7293 up. This fixes display of Arabic diacritics such as KASRA and
7294 KASRATAN. (Bug#11860)
7296 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7298 Be more systematic about _setjmp vs setjmp.

7302 (png_load, my_error_exit, jpeg_load):
7303 * process.c (send_process_trap, send_process):
7304 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7305 The underscored versions are up to 30x faster on some hosts.
7306 Formerly, the code used setjmp+longjmp sometimes and
7307 _setjmp+_longjmp at other times, with no particular reason to
7308 prefer setjmp+longjmp.

7345 * msdos.c (fatal_error_in_progress): ... from here.

7349 REDISPLAYING_P when unwinding, instead of saving its previous,
7350 always-false value and then restoring it.
7352 Clean up some extern decls.
7353 Mostly, this hoists extern decls out of .c files and into .h files.
7354 That way, we're more likely to catch errors if the interfaces change.
7355 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7356 declare xg_mark_data.

7381 * xfaces.c: Remove unnecessary static decls.
7382 * xterm.c (updating_frame): Remove decl of nonexistent object.
7384 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7385 when building globals.h, as the objects that are not built on

7440 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7441 more than one grapheme cluster passed to the shaper: compute the
7442 offset adjustment values separately for each cluster. (Bug#11860)
7444 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7445 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7446 about implicit conversions from integer to pointer.
7448 2012-09-01 Daniel Colascione <dancol@dancol.org>
7450 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7451 system used too early.
7453 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>

7504 window system declarations.
7506 * frame.h: Move common functions here: set_frame_menubar,
7507 x_set_window_size, x_sync, x_get_focus_frame,
7508 x_set_mouse_position, x_set_mouse_pixel_position,
7509 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7570 * lread.c (init_lread): For out-of-tree builds, only add the
7571 source directory's site-lisp dir to the load-path if it exists,
7572 consistent with in-tree builds. (Bug#12302)

7595 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7596 Add window_closed and button_values. Add void as return value for
7597 add(Button|String|Split). addButton takes int instead of Lisp_Object.

7744 (struct iso_2022_spec, struct coding_system):
7745 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7746 (struct emacs_mule_spec): Remove unused field 'full_support'.
7747 All initializations removed.
7748 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7750 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7752 Fix spare memory change (Bug#12286).
7753 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7754 (valid_lisp_object_p): Likewise.
7756 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7758 * window.c (Fset_window_configuration): Record any window's old
7759 buffer if it's replaced (see Bug#8789). If the new current
7760 buffer doesn't appear in the selected window, go to its old
7763 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7765 Special MEM_TYPE_SPARE to denote reserved memory.
7766 * alloc.c (enum mem_type): New memory type.
7767 (refill_memory_reserve): Use new type for spare memory.
7768 This prevents live_cons_p and live_string_p from incorrect
7769 detection of uninitialized objects from spare memory as live.
7771 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7774 * Makefile.in (.PHONY): versioclean -> versionclean.
7776 Remove unused external symbols.
7777 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7778 * window.c (Qwindow_valid_p, decode_valid_window):
7779 Now static, not extern.
7780 * data.c (Qinterval): Remove; unused.
7781 (syms_of_data): Do not define 'interval'.
7782 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7783 * window.h (decode_valid_window):
7786 * character.c, charset.c, chartab.c: Use bool for booleans.
7787 * character.c (lisp_string_width, string_count_byte8)
7788 (string_escape_byte8):
7789 * charset.c (charset_map_loaded, load_charset_map, read_hex):
7790 (load_charset_map_from_file, map_charset_chars)
7791 (Fdefine_charset_internal, define_charset_internal)
7792 (Fdeclare_equiv_charset, find_charsets_in_text)
7793 (Ffind_charset_region, char_charset, Fiso_charset):
7794 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
7795 (sub_char_table_set, sub_char_table_set_range)
7796 (char_table_set_range, optimize_sub_char_table)
7797 (map_sub_char_table):
7798 Use bool for boolean.
7799 * character.c (str_to_unibyte): Omit last boolean argument; it was
7800 always 0. All callers changed.
7801 * character.h, charset.h: Adjust to match previous changes.
7802 * character.h (char_printable_p): Remove decl of nonexistent function.
7803 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7804 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7805 are all boolean, so make them single-bit bitfields.
7807 * lisp.h (ASET): Remove attempt to detect side effects.
7808 It was meant to be temporary and it often doesn't work,
7809 because when IDX has side effects the behavior of IDX==IDX
7810 is undefined. See Stefan Monnier in
7811 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7813 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7815 * lisp.h (functionp): New function (extracted from Ffunctionp).
7816 (FUNCTIONP): Use it.
7817 * eval.c (Ffunctionp): Use it.
7819 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7821 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7822 as that's faster and simpler than static storage. Don't bother
7823 with the g_main_context_query overhead if g_main_context_pending
7824 says no events are pending.
7825 (gfds, gfds_size): Remove these static vars.
7826 (xgselect_initialize): Remove; no longer needed.
7827 All uses and decls removed.
7829 * emacs.c (fatal_error_signal_hook): Remove.
7830 All uses removed. This leftover from old code was always 0.
7832 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7833 * casefiddle.c (casify_object, casify_region):
7834 * casetab.c (set_case_table):
7835 * category.c, category.h (word_boundary_p):
7836 * category.h (CHAR_HAS_CATEGORY):
7837 Use bool for booleans, instead of int.
7839 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7841 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7843 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7845 On assertion failure, print backtrace if available.
7846 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7847 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7848 * Makefile.in (LIB_EXECINFO): New macro.
7851 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7852 * bytecode.c (exec_byte_code):
7853 * callint.c (check_mark, Fcall_interactively):
7854 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7855 (getenv_internal, sync_process_alive, call_process_exited):
7856 * lisp.h (USE_SAFE_ALLOCA):
7857 Use bool for booleans, instead of int.
7858 * lisp.h, process.h: Adjust prototypes to match above changes.
7859 * callint.c (Fcall_interactively): Don't assume the mark's
7860 offset fits in 'int'.
7862 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7864 * buffer.c, buffer.h: Use bool for boolean.
7865 * buffer.c (reset_buffer_local_variables)
7866 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7867 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7868 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7869 (overlay_touches_p, overlay_strings, Foverlay_put)
7870 (report_overlay_modification, call_overlay_mod_hooks):
7871 (mmap_enlarge, mmap_set_vars):
7872 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7873 Use bool for booleans, instead of int.
7874 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7875 since the 1-or-0 return value is always ignored anyway.
7876 (mmap_initialized_p):
7877 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7878 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7880 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7882 * bidi.c: Use bool for boolean.
7883 This is a bit more readable, and makes the text segment of bidi.o
7884 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7885 Presumably it's faster too.
7886 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7888 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7889 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7890 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7891 (bidi_explicit_dir_char, bidi_level_of_next_char)
7892 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7893 Use bool for booleans, instead of int.
7894 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7895 (bidi_unshelve_cache): Adjust decls to match code.
7897 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7899 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7902 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7904 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7905 * atimer.h: Include <stdbool.h>.
7907 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7909 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7910 compile time tests instead of run time tests on systems that do
7912 (FRAME_MAC_P): Remove leftover from deleted code.
7913 * frame.c (syms_of_frame): Remove leftover from deleted code.
7915 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7917 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7919 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7921 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7922 Otherwise, the compiler complains about (A?B:C) where B is void
7923 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7924 (fontset_add): Return void, for FONTSET_ADD.
7926 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7928 * alloc.c: Use bool for booleans.
7929 (gc_in_progress, abort_on_gc)
7930 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7931 (dont_register_blocks) [GC_MALLOC_CHECK]:
7932 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7933 (check_string_bytes, make_specified_string, memory_full)
7934 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7935 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7936 (mark_stack, valid_pointer_p, make_pure_string)
7937 (Fgarbage_collect, survives_gc_p, gc_sweep):
7938 Use bool for booleans, instead of int.
7939 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7940 Remove unused local.
7941 * alloc.c (PURE_POINTER_P):
7942 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7943 * editfns.c (Fformat):
7944 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7946 * fns.c (sweep_weak_table):
7947 * lisp.h (suppress_checking, push_message, survives_gc_p)
7948 (make_pure_string, gc_in_progress, abort_on_gc):
7949 * lread.c (readchar, read1):
7950 * print.c (Fprin1_to_string):
7951 * xdisp.c (push_message):
7952 Use bool for booleans affected directly or indirectly by
7955 Make recently-introduced setters macros.
7956 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7957 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7958 (set_fontset_default, set_fontset_fallback): Rename from their
7959 upper-case counterparts, and make them functions rather than macros.
7960 This is more consistent with the other recently-introduced setters.
7961 These don't need to be inline, since they're local.
7963 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7965 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7966 the loop (Bug#12247).
7968 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7970 * lisp.h (vcopy): Use memcpy rather than our own loop.
7971 This fixes a performance regression introduced by the recent
7972 addition of vcopy. This means 'vcopy' will need to be modified
7973 for a copying collector, but that's OK. Also, tighten the
7974 checking in the assertion.
7976 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7978 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7979 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7980 non-base glyph for the width of the base character, according to
7981 what x_draw_composite_glyph_string_foreground expects.
7982 Generate WADJUST value according to composition_gstring_width's
7983 expectations, to produce correct width of the composed character.
7984 Reverse the sign of the DU offset produced by ScriptPlace.
7986 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7988 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7990 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7992 Avoid direct writes to contents member of struct Lisp_Vector.
7993 * lisp.h (vcopy): New function to copy data into vector.
7994 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7995 * fns.c (Ffillarray): Use ASET.
7996 * keyboard.c (timer_check_2): Use AREF and ASET.
7997 (append_tool_bar_item, Frecent_keys): Use vcopy.
7998 * lread.c (read_vector): Use ASET.
7999 * msdos.c (Frecent_doskeys): Use vcopy.
8000 * xface.c (Finternal_copy_lisp_face): Use vcopy.
8001 (Finternal_merge_in_global_face): Use ASET and vcopy.
8002 * xfont.c (xfont_list_pattern): Likewise.
8004 2012-08-21 Martin Rudalics <rudalics@gmx.at>
8006 * window.c (Fwindow_point): For the selected window always return
8007 the position of its buffer's point.
8008 (Fset_window_point): For the selected window always go in its
8009 buffer to the specified position.
8011 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8013 Setter macros for fontsets.
8014 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8015 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8016 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8019 2012-08-20 Glenn Morris <rgm@gnu.org>
8021 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8022 Don't assume that `ln -f' works.
8024 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8026 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8027 and later about non-assignments with no effect. See discussion at
8028 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8031 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8033 Inline setter functions for Lisp_Objects slots of struct specbinding.
8034 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8037 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8039 * window.c (select_window): Always make selected window's buffer
8042 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8044 Use AREF and ASET for docstrings of category tables.
8045 * category.h (CATEGORY_DOCSTRING): Use AREF.
8046 (SET_CATEGORY_DOCSTRING): Use ASET.
8047 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8049 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8051 Inline setter functions for hash table members.
8052 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8053 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8054 (set_hash_key_and_value, set_hash_index, set_hash_next)
8055 (set_hash_hash): New functions.
8056 * charset.c, fns.c: Adjust users.
8058 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8060 Inline getter and setter functions for per-buffer values.
8061 * buffer.h (per_buffer_default, set_per_buffer_default)
8062 (per_buffer_value, set_per_buffer_value): New functions.
8063 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8064 * buffer.c, data.c: Adjust users.
8066 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8068 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8070 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8072 Rely on <config.h> + <unistd.h> to declare 'environ',
8073 as gnulib does this if the system doesn't.
8074 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8075 Remove declaration. MS-Windows declares it on stdlib.h which is
8076 included by conf_post.h.
8077 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8078 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8079 * vm-limit.c: Include <unistd.h>, for 'environ'.
8081 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8082 (start_of_data): Remove decl; mem-limits.h provides it.
8084 * xdisp.c (handle_invisible_prop): Make it a bit faster
8085 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8087 2012-08-19 Chong Yidong <cyd@gnu.org>
8089 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8092 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
8094 * .gdbinit: Use call instead of set when calling a function in the
8097 * data.c (set_internal): Don't use set_blv_found.
8098 (Fkill_local_variable): Likewise.
8100 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8102 * nsfont.m (ns_ascii_average_width): Ensure the string
8103 ascii_printable is initialized with a null-terminated character
8104 array. Otherwise, it can contain undesired extra characters.
8106 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8108 port new setting code to Sun C 5.8 2005/10/13
8109 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8110 Return void, not Lisp_Object. Otherwise, the compiler
8111 complains about (A?B:C) where B is void and C is Lisp_Object
8112 when compiling CHAR_TABLE_SET, due to the recent change to
8113 the API of sub_char_table_set_contents.
8115 2012-08-18 Chong Yidong <cyd@gnu.org>
8117 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
8118 for the string case (Bug#3874).
8120 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8122 * buffer.h (BSET): Remove (Bug#12215).
8123 Replace all uses with calls to new setter functions.

8151 * category.c (bset_category_table):
8152 * syntax.c (bset_syntax_table):
8153 New setter functions.
8155 * process.h (PSET): Remove (Bug#12215).
8156 Replace all uses with calls to new setter functions.

8158 (PROCESS_INLINE): New macro.
8159 (pset_childp): New setter function.
8160 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
8161 * process.c (PROCESS_INLINE):
8162 Define to EXTERN_INLINE, so that the corresponding functions
8163 are compiled into code.
8164 (pset_buffer, pset_command, pset_decode_coding_system)

8167 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
8168 (pset_type, pset_write_queue): New setter functions.
8170 * window.h (WSET): Remove (Bug#12215).
8171 Replace all uses with calls to new setter functions.
8172 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
8173 (WINDOW_INLINE): New macro.

8177 (wset_window_end_pos, wset_window_end_valid)
8178 (wset_window_end_vpos): New setter functions.
8179 * window.c (WINDOW_INLINE):

9088 (INLINE_HEADER_END): New macros.
9089 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9111 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9113 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9114 This how ASET and AREF are supposed to work, and makes
9115 it easier to think about future improvements. See
9116 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

9529 * alloc.c (listn): Fix the order the arguments are consed onto the
9532 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9533 enumeration constants, as PURE and HEAP are too general, and clash
9534 with other headers and sources, such as gmalloc.c and the
9535 MS-Windows system headers. All users changed.
9537 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9539 Revert last save_excursion_save and save_excursion_restore changes.
9540 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9550 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
9552 Improve GDB symbol export (Bug#12036).
9553 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9554 arms of an 'if', not using conditional expressions; otherwise GDB
9555 complains about the types in the unevaluated arm when the argument
9556 is an integer literal.
9557 (xgetint): Simplify expression.
9558 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9559 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9560 Zaretskii in <http://bugs.gnu.org/12036#13>.
9561 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9562 needed now that we have gdb_make_enums_visible.
9563 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9564 (enum enum_USE_LSB_TAG):
9565 New enum types, packaging up enums that need to be exported to GDB.
9567 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9569 Utility function to make a list from specified amount of objects.

9583 * xdisp.c (syms_of_xdisp): Likewise.
9584 * xfns.c (syms_of_xfns): Likewise.
9586 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9588 Fast save_excursion_save and save_excursion_restore.
9589 * lisp.h (struct Lisp_Excursion): New data type.
9590 (PVEC_EXCURSION): New pseudovector type.
9591 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9592 to deal with it. Adjust comments.
9593 (init_marker, attach_marker): New prototype.
9594 (unchain_marker): Adjust prototype.
9595 * marker.c (attach_marker): Change to global.

9603 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9605 Fix export of symbols to GDB (Bug#12036).
9606 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9607 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9608 emacs.c, as this is a more-suitable home. Had this been done earlier
9609 the fix for 12036 would have avoided some of the problems noted in
9610 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9611 would have been more obvious.
9612 * emacs.c: Do not include <verify.h>; no longer needed.
9613 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9614 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9615 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9616 Remove; now done in lisp.h.
9617 * lisp.h (PUBLISH_TO_GDB): New macro.
9618 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
9619 (DATA_SEG_BITS): Use it.
9620 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9621 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9622 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9623 not be usable in #if. This simplifies things.
9625 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9627 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9629 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9631 Simplify export of symbols to GDB (Bug#12036).
9632 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9633 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9634 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9635 Adjust to changes in lisp.h and emacs.c, by using
9636 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9637 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9638 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9639 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9640 instead of gdb_valbits.
9641 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9642 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9643 instead of gdb_array_mark_flag.
9644 (xboolvector): Get size from $->size, not $->header.size.
9645 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9646 (xreload, hook-run, hookpost-run): Remove.
9647 * emacs.c: Include <verify.h>.
9648 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9649 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9651 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9652 (gdb_USE_LSB_TAG): New enum constants.
9653 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9654 Also define these as enum constants, so they're visible to GDB.
9655 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9656 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9657 as constants, so they're visible to GDB.
9658 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9659 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9660 Now enum constants, not macros, so they're visible to GDB.
9661 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9662 more convenient now. All uses changed.
9663 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9664 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9666 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9671 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9673 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9674 add argument, tune behavior, and adjust all callers.
9676 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9678 Use typedef for EMACS_INT, EMACS_UINT.
9679 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9680 than macros. This simplifies debugging in the usual case, since
9681 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9682 and it allows expressions involving EMACS_INT casts.
9683 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9685 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
9687 * nsterm.m (ns_read_socket): Return early if there is a modal

9693 that FOCUS-FRAME can be omitted.
9695 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9697 Adjust buffer text indirection counters at the end of Fkill_buffer.
9698 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9699 buffer is definitely dead. This should really fix an issue reported
9700 by Christoph Scholtes again. (Bug#12007).
9701 (init_buffer_once): Initialize indirection counters of
9702 buffer_defaults and buffer_local_symbols (for sanity and safety).
9704 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9706 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9707 and continuation glyphs on tooltip frames, leave them at zero.

9710 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
9712 Simplify copy_overlay.
9713 * buffer.c (copy_overlay): Simplify. Use build_marker.

9722 it signals an error when a tooltip frame is being created.
9724 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9726 Cleanup miscellaneous objects allocation and initialization.

9733 (build_overlay): Add prototype.
9735 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9737 Swap buffer text indirection counters in Fbuffer_swap_text.
9738 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9739 This avoids crash reported by Christoph Scholtes at
9740 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9742 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9744 * nsmenu.m (Popdown_data): New struct.
9745 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9747 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9748 (initWithContentRect): Make imgView and contentView non-static
9749 and autorelease them. Also autorelease img and matrix (Bug#12005).
9750 (dealloc): Remove (Bug#12005).
9752 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9754 Adjust consing_since_gc when objects are explicitly freed.

9763 (live_buffer, set_marker_internal): New function.
9764 (Fset_marker, set_marker_restricted): Use set_marker_internal.

9767 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9769 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9770 as it's limited by the amount of memory, not by INT_MAX.
9772 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9774 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9775 in special-event-map. See the discussion at
9776 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
9779 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
9780 info.dwItemData. Fixes crashes on 64-bit Windows.

9834 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
9835 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
9836 Adjust users accordingly.
9837 * font.h (font_open_by_name): Adjust prototype.
9839 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

9855 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
9856 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
9857 'for_each_per_buffer_object_at'.
9858 All uses changed. It's better to use upper-case for macros that
9859 cannot be implemented as functions, to give the reader a clue
9860 that they're special.
9862 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
9864 * alloc.c (Fgarbage_collect): Tweak docstring.

9904 Fix bug that created negative-length intervals.
9905 * intervals.c (merge_interval_right, merge_interval_left):
9906 Do not zero out this interval if it is absorbed by its children,
9907 as this interval's total length doesn't change in that case. See
9908 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
9910 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
9912 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
9913 when invoking (make-bool-vector N t) and N is a positive
9914 multiple of 8 -- the last 8 bits were mistakenly cleared.
9916 Remove some struct layout assumptions in bool vectors.
9917 * alloc.c (bool_header_size): New constant.
9918 (header_size, word_size): Move earlier, as they're now used earlier.
9919 Use 'word_size' in a few more places, where it's appropriate.
9920 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
9921 padding before the data member of a bool vector.
9922 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
9923 than doing the check by hand with an abort ().
9925 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9927 * eval.c (Fdefvar): Don't check constants since we only set the var if
9928 it's not yet defined anyway (bug#11904).
9930 * lisp.h (last_undo_boundary): Declare new var.
9931 * keyboard.c (command_loop_1): Set it.
9932 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
9933 were auto-added by the command loop (bug#11774).
9935 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
9937 * w32font.c (Qsymbol): Remove local definition.

10426 2012-07-11 Glenn Morris <rgm@gnu.org>
10428 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
10429 since nothing has defined it on these platforms.

10441 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
10443 2012-07-11 John Wiegley <johnw@newartisans.com>
10445 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
10446 function attribute, so we only use it if it exists in the
10449 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10451 Avoid call to strlen in fast_c_string_match_ignore_case.
10452 * search.c (fast_c_string_match_ignore_case): Change to use
10453 length argument. Adjust users accordingly.
10454 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
10456 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

10473 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10475 Avoid calls to strlen in font processing functions.
10476 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
10477 (font_open_by_name): Change to use length argument.

10495 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
10497 Remove "#define unix" that is no longer needed (Bug#11905).
10498 * s/aix4-2.h (unix): Remove; no longer needed.
10500 EMACS_TIME simplification (Bug#11875).
10501 This replaces macros (which typically do not work in GDB)
10502 with functions, typedefs and enums, making the code easier to debug.
10503 The functional style also makes code easier to read and maintain.
10504 * systime.h: Include <sys/time.h> on all hosts, not just if
10505 WINDOWSNT, since 'struct timeval' is needed in general.
10506 (EMACS_TIME): Now a typedef, not a macro.
10507 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
10509 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
10510 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

10514 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
10515 which are not functions. All uses rewritten to use:
10516 (make_emacs_time): New function.
10517 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
10518 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
10519 not functions. All uses rewritten to use the following, respectively:
10520 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
10521 (add_emacs_time, sub_emacs_time): New functions.
10522 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
10523 * fileio.c (Fcopy_file):
10524 * xterm.c (XTflash): Get the current time closer to when it's used.
10525 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

10530 * doc.c (Fsnarf_documentation):
10531 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
10532 * frame.c (Fmake_terminal_frame):
10533 * gtkutil.c (get_utf8_string):
10535 * nsmenu.m (ns_update_menubar):
10536 * regex.c (regerror):
10537 Prefer memcpy to strncpy and strncat when either will do.
10538 * fileio.c (Fsubstitute_in_file_name):
10539 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
10540 (menu_separator_name_p):
10541 * nsmenu.m (ns_update_menubar):
10542 Prefer memcmp to strncmp when either will do.
10543 * nsterm.m: Include <ftoastr.h>.
10545 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10546 Prefer snprintf to strncpy.
10547 * nsterm.m (ns_term_init):
10548 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10549 * nsterm.m (ns_term_init):
10550 Avoid the need for strncpy, by using build_string or
10551 make_unibyte_string directly. Use dtoastr, not snprintf.
10552 * process.c (Fmake_network_process): Diagnose service names that
10553 are too long, rather than silently truncating them or creating
10554 non-null-terminated names.
10555 (Fnetwork_interface_info): Likewise, for interface names.
10556 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10557 Prefer sprintf to strncat.
10558 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10559 Prefer vsnprintf to vsprintf + strncpy.
10561 2012-07-10 Glenn Morris <rgm@gnu.org>
10563 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
10564 Clarify fallback case.
10566 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10568 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10569 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10570 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10571 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10572 where argument type is known to be a Lisp_Cons.
10574 2012-07-10 Tom Tromey <tromey@redhat.com>
10576 * bytecode.c (BYTE_CODE_THREADED): New macro.
10577 (BYTE_CODES): New macro. Replaces all old byte-code defines.
10578 (enum byte_code_op): New type.
10579 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
10580 (exec_byte_code): Use them. Use token threading when applicable.
10582 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10584 Optimize pure C strings initialization.
10585 * lisp.h (make_pure_string): Fix prototype.
10586 (build_pure_c_string): New function, defined as static inline. This
10587 provides a better opportunity to optimize away calls to strlen when
10588 the function is called with compile-time constant argument.
10589 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10590 argument, adjust users accordingly. Use build_pure_c_string where
10592 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10593 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10594 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10596 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10598 Avoid calls to strlen in miscellaneous functions.
10599 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10600 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10601 * lread.c (openp): Likewise.
10603 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10605 Avoid calls to strlen in path processing functions.
10606 * fileio.c (file_name_as_directory): Add comment. Change to add
10607 srclen argument and return the length of result. Adjust users
10609 (directory_file_name): Fix comment. Change to add srclen argument,
10610 swap 1st and 2nd arguments to obey the common convention.
10611 Adjust users accordingly.
10612 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10614 2012-07-10 Glenn Morris <rgm@gnu.org>
10616 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
10617 Move PENDING_OUTPUT_COUNT definition to configure.
10619 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10620 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10621 * s/gnu.h (DATA_START): Move definitions to configure.
10623 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10624 We include usg5-4-common.h, which defines them both.
10626 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10627 O_RDONLY already includes it).
10629 Stop ns builds setting the EMACSLOADPATH environment variable.
10630 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10631 Now it does not set EMACSLOADPATH, just returns the load-path string.
10632 * nsterm.h: Update accordingly.
10633 * lread.c [HAVE_NS]: Include nsterm.h.
10634 (init_lread) [HAVE_NS]: Use ns_load_path.
10635 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10637 2012-07-09 Glenn Morris <rgm@gnu.org>
10639 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10640 since the included bsd-common.h does so.
10642 Stop ns builds setting the EMACSPATH environment variable.
10643 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10644 (ns_init_paths): Do not set EMACSPATH.
10645 * nsterm.h (ns_exec_path): Add it.
10646 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10649 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10651 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10653 * process.c (wait_reading_process_output): 'waitchannels' was unset
10654 when read_kbd || !NILP (wait_for_cell); fix this.
10656 Add GCC-style 'const' attribute to functions that can use it.
10657 * character.h (char_resolve_modifier_mask):
10658 * keyboard.h (make_ctrl_char):
10659 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10660 (init_character_once, next_almost_prime, init_fns, init_image)
10661 (flush_pending_output, init_sound):
10662 * mem-limits.h (start_of_data):
10663 * menu.h (finish_menu_items):
10664 Add ATTRIBUTE_CONST.
10665 * emacs.c (DEFINE_DUMMY_FUNCTION):
10666 Declare the dummy function with ATTRIBUTE_CONST.
10667 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
10668 Add decls with ATTRIBUTE_CONST.
10670 Minor improvements to make_formatted_string.
10671 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10672 where int is good enough, as vsprintf returns an int.
10673 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10675 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10677 Use make_formatted_string to avoid double length calculation.
10678 * lisp.h (make_formatted_string): New prototype.
10679 * alloc.c (make_formatted_string): New function.
10680 * buffer.c (Fgenerate_new_buffer_name): Use it.
10681 * dbusbind.c (syms_of_dbusbind): Likewise.
10682 * editfns.c (Fcurrent_time_zone): Likewise.
10683 * filelock.c (get_boot_time): Likewise.
10684 * frame.c (make_terminal_frame, set_term_frame_name)
10685 (x_report_frame_params): Likewise.
10686 * image.c (gs_load): Likewise.
10687 * minibuf.c (get_minibuffer): Likewise.
10688 * msdos.c (dos_set_window_size): Likewise.
10689 * process.c (make_process): Likewise.
10690 * xdisp.c (ensure_echo_area_buffers): Likewise.
10691 * xsettings.c (apply_xft_settings): Likewise.
10693 2012-07-09 Glenn Morris <rgm@gnu.org>
10695 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10696 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10697 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10699 * callproc.c [HAVE_NS]: Include nsterm.h.
10700 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10702 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10704 Move marker debugging code under MARKER_DEBUG.
10705 * marker.c (MARKER_DEBUG): Move marker debugging code under
10706 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10707 for bootstrap with --enable-checking (~3x slowdown reported
10708 by Juanma Barranquero <lekktu@gmail.com>).
10709 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10711 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10713 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10714 See <http://bugs.gnu.org/11825#29>.
10716 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10718 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10719 has no font, use the frame's font. (Bug#11813)
10720 (display_line): Add commentary about displaying truncation glyphs
10722 (produce_special_glyphs): Move here from term.c.
10724 * term.c (produce_special_glyphs): Move to xdisp.c.
10726 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10729 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10731 * xdisp.c (display_line): Avoid warning about implicit declaration
10734 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10736 * lisp.h: Remove empty conditional.
10738 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10740 * lread.c (load_path_check): Now static.
10742 Fix some minor --with-ns problems found by static checking.
10743 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10744 (x_set_font) [!HAVE_X_WINDOWS]:
10745 * image.c (xpm_load_image) [HAVE_NS]:
10746 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10747 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10748 Remove unused local.
10749 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10750 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10751 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10752 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10753 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10754 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10755 Fix pointer signedness problem.
10756 * xfaces.c (FRAME_X_FONT_TABLE):
10757 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10759 2012-07-07 Glenn Morris <rgm@gnu.org>
10761 * lread.c (load_path_check): New function, split from init_lread.
10762 (init_lread): Reorganize. Motivation:
10763 If EMACSLOADPATH is set, check/warn about that rather than the
10764 defaults, which we are not going to use. Hence we can remove
10765 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10766 Don't warn if site-lisp directories are missing.
10767 If not installed, start from a blank load-path, since
10768 PATH_LOADSEARCH refers to the eventual installation directories.
10770 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10772 Support truncation and continuation glyphs on GUI frames, when
10773 fringes are disabled. (Bug#11832)
10774 * xdisp.c (init_iterator): Get dimensions of truncation and
10775 continuation glyphs even if on GUI frames.
10776 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10777 or both, are absent.
10778 (start_display, move_it_in_display_line_to): Handle the case of a
10779 GUI frame without a fringe to display continuation or truncation
10781 (insert_left_trunc_glyphs): Support GUI frames: make sure
10782 truncation glyphs overwrite enough glyphs from the current line to
10783 have sufficient space in pixels.
10784 (display_line): Support truncation and continuation glyphs on GUI
10785 frames. If some spare pixels are left on the line after inserting
10786 the truncation glyphs, fill that space with a stretch glyph of a
10787 suitably computed width.
10789 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10790 produce_glyphs, to support GUI sessions.
10792 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10794 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10796 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10798 Do not require float-time's arg to fit in time_t (Bug#11825).
10799 This works better on hosts where time_t is unsigned, and where
10800 float-time is applied to the (negative) difference between two times.
10801 * editfns.c (decode_time_components): Last arg is now double *,
10802 not int *, and means to store all the result as a double, without
10803 worrying about whether the seconds part fits in time_t.
10804 All callers changed.
10805 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10806 All callers changed.
10807 (Ffloat_time): Do not fail merely because the specified time falls
10808 outside of time_t range.

10843 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10844 Eli Zaretskii <eliz@gnu.org>
10846 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10847 Windows-specific code from nt/config.nt moved here.
10848 Obsolete settings removed.
10850 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10852 * process.c: Avoid unnecessary calls to gettime.
10853 (wait_reading_process_output): Don't get the time of day
10854 when gobbling data immediately and not waiting, as there's no need
10855 for it in that case. This removes a FIXME.
10857 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10859 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10860 is defined (Bug#11768).

10868 Call byte_char_debug_check with correct arguments.
10870 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10872 Compile marker debugging code only if ENABLE_CHECKING is defined.
10873 * marker.c (byte_char_debug_check, count_markers):
10874 Use only if ENABLE_CHECKING is defined.
10875 (byte_debug_flag): Remove.
10876 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10877 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

10912 to avoid redundant calls to unchain_overlay.
10913 * buffer.c (drop_overlay): New function.
10914 (delete_all_overlays, Fdelete_overlay): Use it.
10915 * minibuf.c (get_minibuffer): Fix comment.
10917 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10919 Port to OpenBSD 5.1 amd64.
10920 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10921 This is needed for OpenBSD, and should be harmless on all BSD systems.
10922 Also, include <sys/sysctl.h>, as it should be available on all
10923 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10924 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10925 use p_pid member, not kp_proc.pid.
10927 2012-07-06 Glenn Morris <rgm@gnu.org>
10929 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.

10942 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10944 Omit needless casts involving void * pointers and allocation.
10945 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10946 as the former is more robust if P's type is changed.
10947 Prefer xzalloc to xmalloc + memset 0.
10948 Simplify malloc-or-realloc to realloc.
10949 Don't worry about xmalloc returning a null pointer.
10950 Prefer xstrdup to xmalloc + strcpy.

10958 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10959 hscroll is larger than the line width. Fixes long and futile
10960 looping inside extend_face_to_end_of_line (on a TTY) producing
10961 glyphs that are not needed and thrown away.
10963 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10965 * marker.c (set_marker_restricted_both): Simplify by using
10968 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10970 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10979 followed by gtk_box_set_homogeneous (Bug#11768).
10980 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10981 (update_theme_scrollbar_width, xg_create_scroll_bar):

10985 (xg_tool_item_stale_p): Call is_box_type.
10986 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10987 with default display (Bug#11768).
10989 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10991 * xdisp.c (window_hscroll_limited): New function.
10992 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10993 coordinates when window's hscroll is set to insanely large
10994 values. (Bug#11857)
10996 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11060 Problem reported by Troels Nielsen in
11061 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11063 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11065 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11066 This should be fixed in a better way; see Eli Zaretskii in
11067 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11068 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11070 * fileio.c (time_error_value): Rename from special_mtime.
11071 The old name's problems were noted by Eli Zaretskii in
11072 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11074 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11075 This variable's comment says Emacs needs at least one GDB-visible
11076 symbol of type enum pvec_type, to work around GDB problems.
11077 The symbol's value doesn't matter.
11079 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11080 that causes compilation to fail on pre-C99 compilers.
11082 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11084 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

11108 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11109 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11110 abusing vector->header.next.nbytes.
11111 (live_vector_p): Use PVEC_TYPE.
11112 (mark_object): Adapt code to extract pvectype. Use switch.
11114 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>

11121 Fix compilation with --enable-gcc-warnings and -O1
11122 optimization level.

11124 to avoid compiler warning. Add eassert.
11125 * search.c (simple_search): Initialize match_byte to avoid
11126 compiler warning. Add eassert.
11128 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11130 Avoid weird behavior with large horizontal scrolls.
11131 Without this change, for example, large hscroll values would
11132 mess up Emacs's display on Fedora 15 x86, presumably due to
11133 overflows in int calculations in the display code.
11134 Also, if buffers had long lines, Emacs would freeze.
11135 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11136 (set_window_hscroll): New function, containing the old guts of
11137 Fset_window_hscroll. Return the clipped value.
11138 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11139 This avoids the need to check against PTRDIFF_MAX.
11141 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11143 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11145 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11147 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11149 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11150 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11151 since GCC 4.4.6 issues a bogus warning for them.
11153 Fix bugs in file timestamp newness comparisons.
11154 * fileio.c (Ffile_newer_than_file_p):
11155 * lread.c (Fload): Use full timestamp resolution of files,
11156 not just the 1-second resolution, so that files that are only
11157 slightly newer still count as newer.
11158 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11159 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11161 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11163 * fileio.c: Improve handling of file time marker. (Bug#11852)

11173 2012-07-03 Glenn Morris <rgm@gnu.org>
11175 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11176 and did not make it into globals.h).
11178 2012-07-03 Tom Tromey <tromey@redhat.com>

11238 * alloc.c (allocate_vector_block): Remove redundant
11239 calls to mallopt if DOUG_LEA_MALLOC is defined.
11240 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11241 avoid calls to mallopt if zero_vector is returned.
11243 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11245 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11246 is enabled, avoid dereferencing NULL current_sblock if
11249 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11251 Cleanup basic buffer management.
11252 * buffer.h (struct buffer): Change layout to use generic vector
11253 marking code. Fix some comments. Change type of 'clip_changed'
11254 to bitfield. Remove unused #ifndef old.
11255 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11256 (GET_OVERLAYS_AT): Fix indentation.
11257 (for_each_per_buffer_object_at): New macro.
11258 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
11259 (Fbuffer_local_variables): Use it.
11260 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
11261 * alloc.c (allocate_buffer): Adjust to match new layout of
11262 struct buffer. Fix comment.
11263 (mark_overlay): New function.
11264 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11265 Lisp area of struct buffer.
11266 (mark_object): Use it. Adjust marking of misc objects
11267 and related comments.
11269 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11271 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11272 wrapper that is not needed because the wrapped code is a no-op (zero
11273 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11274 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11276 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11278 * alloc.c (mark_buffer): Simplify. Remove prototype.
11279 (mark_object): Add comment. Reorganize marking of vector-like
11280 objects. Use CHECK_LIVE for all vector-like objects except buffers
11281 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11282 Avoid redundant calls to mark_vectorlike for bool vectors.
11284 2012-06-30 Glenn Morris <rgm@gnu.org>
11286 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11288 * epaths.in (PATH_SITELOADSEARCH): New.
11289 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11290 This is rather than relying on --enable-locallisppath elements
11291 having "site-lisp" in their names. (Bug#10208#25, 11658)
11293 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11295 * w32proc.c (sys_select): Accept and ignore one more argument.
11297 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11299 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11300 (pselect) [!MS_DOS]: Redirect to sys_select.
11302 * sysdep.c: Don't include dos.h and dosfns.h.
11304 * process.c (sys_select):
11305 * msdos.c (sys_select): Accept one more argument and ignore it.
11307 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11308 adapt data types and code to that.
11311 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11312 which clashes with the gnulib function of the same name.
11314 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11316 * font.c (font_style_to_value, font_style_symbolic)
11317 (font_prop_validate_style): Add type checks for values in
11320 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11322 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11325 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11327 * xdisp.c (try_window_id): Undo last change.
11329 * w32.c (getwd): Adjust commentary about startup_dir.
11330 (init_environment): Always call sys_access, even in non-MSVC
11331 builds. Don't chdir to the directory of the Emacs executable.
11332 This undoes code from 1997 which was justified by the need to
11333 "avoid conflicts when removing and renaming directories". But its
11334 downside was that every relative file name was being interpreted
11335 relative to the directory of the Emacs executable, which can never
11336 be TRT. In particular, it broke sys_access when called with
11337 relative file names.
11338 (sys_access): Map GetLastError to errno.
11340 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11342 * window.h (struct window): Change type of 'fringes_outside_margins'
11343 to bitfield. Fix comment. Adjust users accordingly.
11344 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
11346 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11349 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11351 * gnutls.c (emacs_gnutls_handshake):
11352 Add QUIT to make the loop interruptible.
11354 2012-06-29 Glenn Morris <rgm@gnu.org>
11356 * charset.c (init_charset): Make lack of etc/charsets fatal.
11358 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11360 * editfns.c (region_limit): Fix type mismatch.
11362 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
11364 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11365 undefined. Convert from xassert to eassert.
11366 * nsmenu.m: Convert from xassert to eassert.
11367 * nsterm.m: Likewise.
11369 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
11371 * editfns.c (region_limit): Clip to narrowing (bug#11770).
11373 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11375 Avoid integer overflow on scroll-left and scroll-right.
11376 * window.c (HSCROLL_MAX): New macro.
11377 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11378 overflow when requested scroll falls outside ptrdiff_t range.
11380 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11382 * window.h (struct window): Change type of 'hscroll',
11383 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11384 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11385 Adjust users accordingly.
11386 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11387 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11388 from EMACS_INT to ptrdiff_t.
11389 (make_window): Omit redundant initialization.
11391 2012-06-28 Juanma Barranquero <lekktu@gmail.com>

11395 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11397 * window.h (struct window): Change type of 'use_time' and
11398 'sequence_number' from Lisp_Object to int.

11407 enabled with --enable-checking=[all,glyphs] configure option.
11408 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11409 adjust comments accordingly.

11411 undefined, adjust comments accordingly.

11453 * fns.c (maybe_resize_hash_table): Output message when growing the
11456 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
11458 * alloc.c (allocate_string_data): Remove dead code.
11459 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
11460 avoid GCC warning about unused macro.
11462 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
11464 * alloc.c (allocate_string): Omit intervals initialization.

11522 * alloc.c: Remove build_string.
11523 * lisp.h: Define build_string as static inline. This provides
11524 a better opportunity to optimize away calls to strlen when the
11525 function is called with compile-time constant argument.
11526 * image.c (imagemagick_error): Convert to build_string.
11527 * w32proc.c (sys_spawnve): Likewise.

11530 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11532 Use sprintf return value instead of invoking strlen on result.
11533 In the old days this wasn't portable, since some sprintf
11534 implementations returned char *. But they died out years ago and
11535 Emacs already assumes sprintf returns int.
11536 Similarly for float_to_string.
11537 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
11538 * ccl.c (ccl_driver):

11542 * print.c (print_object):
11543 * xdisp.c (message_dolog):
11544 * xfns.c (syms_of_xfns):
11545 Use sprintf or float_to_string result to avoid need to call strlen.
11546 * data.c (Fnumber_to_string):
11547 Use make_unibyte_string, since the string must be ASCII.
11548 * lisp.h, print.c (float_to_string): Now returns int length.
11549 * term.c (produce_glyphless_glyph):
11550 Use sprintf result rather than recomputing it.
11552 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11553 * Makefile.in (ALL_CFLAGS):
11554 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
11555 * gmalloc.c, regex.c: Include <config.h> unconditionally.
11557 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11559 * dispextern.h (xstrcasecmp): Define to library function
11560 strcasecmp if available.
11561 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
11563 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
11565 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

11578 * gtkutil.c (get_utf8_string): Remove redundant assignment.
11579 sprintf already null-terminates its output.
11581 * xfns.c (x_window): Remove redundant cast.
11583 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11585 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11586 `const char *' to `char *' to avoid compiler warning.
11588 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11590 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11591 instead of truncating it to 63 (admittedly a generous limit).
11593 * process.c: Fix spelling and caps in comments.
11595 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11597 * emacs.c (setpgrp): Remove definition, unused.
11598 * sysdep.c (setpgrp): Remove definition, not used in this file.

11607 (SYSTIME_H): Add nt/inc/sys/time.h.
11609 * systime.h [WINDOWSNT]: Include sys/time.h.
11611 * s/ms-w32.h (struct timespec): Definition moved from
11612 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.

11642 No need for separate decl merely because of _Noreturn.
11643 * sound.c (sound_warning, parse_sound):
11644 Remove unnecessary forward decls.
11646 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11648 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
11649 * lisp.h (WAIT_READING_MAX): New macro.
11650 * dispnew.c (Fsleep_for, sit_for):
11651 * keyboard.c (kbd_buffer_get_event):
11652 * process.c (Faccept_process_output):
11653 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11654 This improves on the previous patch, which introduced a bug
11655 when time_t is unsigned and as wide as intmax_t.
11656 See <http://bugs.gnu.org/9000#51>.
11658 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11674 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
11675 Privately reported by Herbert J. Skuhra.
11676 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
11678 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
11679 not make_lisp_timeval, when the argument is of type EMACS_TIME.
11681 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11686 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
11687 language ID in the event parameters.
11689 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11690 event.code, not the obscure "character set ID".
11692 2012-06-23 Chong Yidong <cyd@gnu.org>
11694 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

11708 in the logic of incrementing and decrementing the value of
11709 use_relocatable_buffers.

11723 Support higher-resolution time stamps (Bug#9000).
11724 The time stamps are only nanosecond-resolution at the C level,
11725 since that's the best that any real-world system supports now.
11726 But they are picosecond-resolution at the Lisp level, as that's
11727 easy, and leaves room for future OS improvements.
11729 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11732 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11733 Don't get current time unless it's needed.

11736 now provides it if it's absent.
11737 (start_atimer): Port to higher-res time stamps.
11738 Check for time stamp overflow. Don't get current time more
11739 often than is needed.

11789 Port to higher-resolution time stamps. Do not assume time_t is signed.
11790 (decode_timer): New function. Timers are now vectors of length 9,
11791 not 8, to accommodate the picosecond component.
11792 (timer_check_2): Use it.
11794 * nsterm.m (select_timeout, timeval_subtract): Remove.
11795 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11796 as they're a bit more accurate and handle overflow better.

11799 * nsterm.h (ns_select): Adjust prototype.

11818 (Faccept_process_output, wait_reading_process_output):
11819 Check for time stamp overflow. Do not assume time_t is signed.
11820 (select_wrapper): Remove; we now use pselect.
11821 (Fprocess_attributes): Now generates ns-resolution time stamps.
11823 * sysdep.c: Include utimens.h. Don't include utime.h
11824 or worry about struct utimbuf; gnulib does that for us now.
11825 (gettimeofday): Remove; gnulib provides a substitute.
11826 (make_timeval): New function.
11827 (set_file_times): Now sets ns-resolution time stamps.
11828 New arg FD; all uses changed.

11831 Now returns ns-resolution time stamp. All uses changed.
11832 Check for time stamp overflow.

11835 provides a substitute now.
11837 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11838 since it guarantees struct timespec.
11839 (EMACS_TIME): Now struct timespec, so that we can support
11840 ns-resolution time stamps.
11841 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11842 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11843 (EMACS_USECS): Remove.
11844 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11845 so multiply the arg by 1000 before storing it.
11846 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11848 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

11855 (make_timeval, make_lisp_time, decode_time_components): New decls.
11856 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11857 that it mishandled time_t overflow. You can't compare by subtracting!
11858 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11859 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

11877 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11878 for compatibility with pselect. Support ns-resolution time stamps.

11882 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11883 Check for time stamp overflow, and support ns-resolution time stamps.

11886 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11887 (timeval_subtract): Remove; no longer needed.
11888 (XTflash, XTring_bell, x_wait_for_event):
11889 Port to ns-resolution time stamps. Don't assume time_t is signed.

11898 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11899 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11900 staticidx goes up to 1597 out of 1600 = 0x640.)
11902 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11904 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

11948 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11950 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11951 gets killed during executing of this function (Bug#11665).
11952 Try to always return Qt when the buffer has been actually killed.
11953 (Vkill_buffer_query_functions): In doc-string say that functions
11954 run by this hook should not change the current buffer.

11978 * lisp.h (eassert): Assume C89 or later.
11979 This removes the need for CHECK.
11980 (CHECK): Remove. Its comments about always evaluating its
11981 argument were confusing, as 'eassert' typically does not evaluate
11984 * coding.c (produce_chars): Use ptrdiff_t, not int.
11986 * xterm.c (x_draw_underwave): Check for integer overflow.
11987 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

12168 -DUSE_LSB_TAG=0, to override the automatically-selected default.
12169 USE_LSB_TAG now is always defined to be either 0 or 1.
12171 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
12172 code works fine either way, and efficiency is not a concern here,
12173 as the union type is for debugging, not for production.
12174 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12175 Use an inline function on all platforms when using the union type,
12176 since this is simpler and 'static inline' can be used portably
12178 (LISP_INITIALLY_ZERO): New macro.
12179 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
12180 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

12207 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
12208 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
12209 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
12211 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
12213 * alloc.c (make_byte_code): New function.

12269 * dispnew.c (showing_window_margins_p): Undo last change, which
12270 was done due to an inadvertent commit.
12271 (adjust_frame_glyphs_for_frame_redisplay): Do call

12280 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
12282 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
12283 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
12285 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12287 * alloc.c (allocate_vectorlike): Fix last change.
12289 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
12291 Block-based vector allocation of small vectors.
12292 * lisp.h (struct vectorlike_header): New field `nbytes',
12293 adjust comment accordingly.
12294 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
12295 to denote vector blocks. Adjust users (live_vector_p,
12296 mark_maybe_pointer, valid_lisp_object_p) accordingly.

12318 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
12320 * doprnt.c (doprnt): Truncate multibyte char correctly.
12321 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12322 would mishandle a string argument "Xc" if X was a multibyte
12323 character of length 2: it would truncate after X's first byte
12324 rather than including all of X.
12326 2012-06-06 Chong Yidong <cyd@gnu.org>
12328 * buffer.c (word_wrap): Doc fix.
12330 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

12375 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12377 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12378 Convert pctcpu and pctmem to Lisp float properly.
12379 Let the compiler fold better, as 100.0/0x8000 is exact.
12381 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12383 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12386 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

12390 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12392 For a 'struct window', replace some Lisp_Object fields to
12393 bitfields where appropriate, remove unused fields.
12394 * window.h (struct window): Remove unused 'last_mark_x' and
12395 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12396 change its type from Lisp_Object to bitfield.
12397 Change type of 'force_start', 'optional_new_start',
12398 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
12399 fields from Lisp_Object to bitfield. Adjust users accordingly.
12401 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12403 Pacify gcc -Wdouble-precision when using Xaw.
12404 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12405 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12406 Use 'float' consistently, rather than 'float' in most places
12407 and 'double' in a couple of places.
12409 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12411 * xdisp.c (handle_stop): Detect whether we have overlay strings
12412 loaded by testing it->current.overlay_string_index to be
12413 non-negative, instead of checking whether n_overlay_strings is
12414 positive. (Bug#11587)
12416 2012-05-31 Chong Yidong <cyd@gnu.org>
12418 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12422 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12424 * search.c (search_buffer): Remove calls to
12425 r_alloc_inhibit_buffer_relocation, as it is now called by
12426 maybe_unify_char, which was the cause of relocation of buffer text
12429 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12431 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12432 for the duration of call to load_charset, to avoid problems with
12433 callers of maybe_unify_char that access buffer text through C
12436 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12437 decrement the inhibition flag, instead of just setting or
12440 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12442 Remove obsolete '#define static' cruft.
12443 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12444 This #undef was "temporary" in 2000; it is no longer needed
12445 now that '#define static' has gone away.
12446 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12447 (gray_bitmap_bits): Remove; no longer needed.
12448 All uses replaced with definiens.

12454 The following changes affect the code only when profiling.
12455 * dispnew.c (__executable_start): Rename from safe_bcopy.
12456 Define only on platforms that need it.
12457 * emacs.c: Include <sys/gmon.h> when profiling.
12458 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12459 (__executable_start): Remove decl, since lisp.h does it now.
12460 (safe_bcopy): Remove decl; no longer has that name.
12461 (main): Coalesce #if into single bit of code, for simplicity.
12462 Cast pointers to uintptr_t, since standard libraries want integers
12464 * lisp.h (__executable_start): New decl.
12466 2012-05-31 Glenn Morris <rgm@gnu.org>
12468 * image.c (Fimagemagick_types): Doc fix.

12489 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
12491 Do not create empty overlays with the evaporate property (Bug#9642).
12492 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12493 Bug#9642, but explicitly check that the buffer the overlay would
12494 be moved to is live and rearrange lines to make sure that errors
12495 will not put the overlay in an inconsistent state.
12496 (Fdelete_overlay): Cosmetics.
12498 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12500 * w32term.c (my_bring_window_to_top): New function.
12501 (x_raise_frame): Use handle returned by DeferWindowPos, which
12502 could be different from the original one.

12512 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12514 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12515 This avoids undefined behavior that might cause the eassert
12516 to not catch an out-of-range value.
12518 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12520 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

12532 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12534 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12535 Only r_alloc_inhibit_buffer_relocation needed to be added;
12536 the others were already declared.
12538 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12539 before checking whether it's out of range. Put the check inside
12541 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12543 2012-05-27 Ken Brown <kbrown@cornell.edu>
12545 * callproc.c (Fcall_process): Restore a line that was accidentally
12546 commented out in the 2011-02-13 change (bug#11547).

12550 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12551 defined on ralloc.c.
12553 * buffer.c [REL_ALLOC]: Remove prototypes of
12554 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12555 they are now on lisp.h.
12557 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12559 * search.c (search_buffer): Use it to inhibit relocation of buffer
12560 text while re_search_2 is doing its job, because re_search_2 is
12561 passed C pointers to buffer text. (Bug#11519)
12563 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12564 Update value to 24.
12566 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12567 state after an additional call to move_it_in_display_line_to, keep
12568 the values of it->max_ascent and it->max_descent found for the
12570 (pos_visible_p): Revert the comparison against bottom_y to what it
12571 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12574 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12576 Fix coding-related core dumps with gcc -ftrapv.
12577 The code was computing A - B, where A and B are pointers, and B is
12578 random garbage. This can lead to core dumps on platforms that
12579 have special pointer registers, and it also leads to core dumps on
12580 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12581 A - B only when B is initialized properly.
12582 * coding.c (coding_set_source, coding_set_destination): Return void.
12583 (coding_change_source, coding_change_destinations): New functions,
12584 with the old behaviors of coding_set_source and coding_set_destination.
12585 All callers that need an offset changed to use these new functions.

12595 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12597 * w32console.c: Include window.h.
12598 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12600 (initialize_w32_display): Initialize mouse-highlight data.
12602 * w32inevt.c: Include termchar.h and window.h.
12603 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12604 moves, call note_mouse_highlight. If help_echo changed, call
12605 gen_help_event to produce help-echo message in the echo area.
12606 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12609 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12611 * lread.c (read1): Simplify slightly to avoid an overflow warning
12612 with GCC 4.7.0 on x86-64.
12614 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12616 * bidi.c (bidi_mirror_char): Revert last change: an int is
12617 definitely wide enough here.
12619 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12621 Fix integer width and related bugs (Bug#9874).
12622 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
12623 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
12624 (string_bytes, check_sblock, allocate_string_data):
12625 (compact_small_strings, Fmake_bool_vector, make_string)

12655 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12656 (validate_region): Omit unnecessary test for b <= e,
12657 since that's guaranteed by the previous test.
12658 (adjust_overlays_for_delete): Avoid pos + length overflow.
12659 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12660 (report_overlay_modification):
12661 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12662 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12663 Omit pointer cast, which isn't needed anyway, and doesn't work
12664 after the EMACS_INT -> ptrdiff_t change.
12665 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12666 * buffer.h: Adjust decls to match defn changes elsewhere.

12671 not int, to avoid needless 32-bit limit on 64-bit hosts.
12672 (exec_byte_code): Use tighter memory-full test, one that checks
12673 for alloca overflow. Don't compute the address of the object just
12674 before an array, as that's not portable. Use EMACS_INT, not
12675 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12676 * callint.c (Fcall_interactively):
12677 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12678 * callproc.c (call_process_kill, Fcall_process):

12689 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12690 (casify_object): Avoid integer overflow when overallocating buffer.
12691 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12692 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12693 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12694 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12695 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

12698 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12699 For CCL_MapSingle, check that content and value are in int range.
12700 (ccl_driver, Fregister_code_conversion_map):
12701 Check that Vcode_version_map_vector is a vector.
12702 (resolve_symbol_ccl_program): Check that vector header is in range.
12703 Always copy the vector, so that we can check its contents reliably
12704 now rather than having to recheck each instruction as it's being
12705 executed. Check that vector words fit in 'int'.
12706 (ccl_get_compiled_code, Fregister_ccl_program)
12707 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12708 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

12710 contents are in range.
12711 (Fccl_execute_on_string): Check that status is in range.
12712 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12713 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12714 Accept and return EMACS_INT, not int, because callers can pass values

12721 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12722 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12723 avoid mishandling large integers.

12732 Remove now-unnecessary CHECK_NATNUMs.
12733 (Fdefine_charset_internal): Check ranges here, more carefully.
12734 Don't rely on undefined behavior with signed left shift overflow.
12735 Don't assume unsigned int fits into fixnum, or that fixnum fits
12736 into unsigned int. Don't require max_code to be a valid fixnum;
12737 that's not true for gb10830 4-byte on a 32-bit host. Allow
12738 invalid_code to be a cons, for the same reason. Require code_offset
12739 to be a character. Avoid int overflow if max_char is close
12741 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12742 this is intended anyway and avoids some undefined behavior.
12743 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12744 INDEX_TO_CODE_POINT, as that's what it expects.
12745 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12746 * charset.h (DECODE_CHAR): Return int, not unsigned;
12747 this is what was intended anyway, and it avoids undefined behavior.
12748 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12749 integer-overflow issues.
12750 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12751 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12752 where the argument is EMACS_INT, and this behavior is not intended.
12753 * chartab.c (Fmake_char_table, Fset_char_table_range)
12754 (uniprop_get_decoder, uniprop_get_encoder):
12755 Don't assume fixnum fits in int.
12756 * cmds.c (move_point): New function, that does the gist of
12757 Fforward_char and Fbackward_char, but does so while checking
12758 for integer overflow more accurately.
12759 (Fforward_char, Fbackward_char): Use it.
12760 (Fforward_line, Fend_of_line, internal_self_insert)
12761 (internal_self_insert):
12762 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13531 (Fword_search_forward, Fword_search_backward_lax)
13532 (Fword_search_forward_lax): Move functions to isearch.el

13535 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13537 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13539 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13541 * lread.c (init_obarray): Declare Qt and Qnil as special.
13543 2012-05-14 Glenn Morris <rgm@gnu.org>
13545 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13546 Put "libexec" before "bin", for the sake of init_callproc_1.
13548 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13550 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

13553 (report_error, report_error_1, make_hdr, copy_sym)
13554 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13555 Make arguments const char *, not char *, to avoid violations of C
13556 standard and to fix some AIX warnings reported by Gilles Pion.
13558 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13560 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13561 already have overlays loaded.
13562 (handle_single_display_spec): Before returning without displaying
13563 fringe bitmap, synchronize the bidi iterator with the main display
13564 iterator, by calling iterate_out_of_display_property.
13565 (iterate_out_of_display_property): Detect buffer iteration by
13566 testing that it->string is a Lisp string.
13567 (get_next_display_element): When the current object is exhausted,
13568 and there's something on it->stack, call set_iterator_to_next to
13569 proceed with what's on the stack, instead of returning zero.
13570 (set_iterator_to_next): If called at the end of a Lisp string,
13571 proceed to consider_string_end without incrementing string
13572 position. Don't increment display vector index past the end of
13573 the display vector. (Bug#11417)
13574 (pos_visible_p): Don't report a position visible when move_it_to
13575 stopped at the last line of window, which happens to be scanned
13576 backwards by the bidi iteration. (Bug#11464)
13578 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13580 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13581 and right-margin display specs even if the spec is invalid or we
13582 are on a TTY, and thus unable to display on the fringes.
13583 That's because the text with the property will not be displayed anyway,
13584 so we need to signal to the caller that this is a "replacing"
13585 display spec. This fixes display when the spec is invalid or we
13588 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13590 * unexaix.c (make_hdr): Fix typo in prototype.
13591 This bug broke the build on AIX. Problem reported by Gilles Pion.
13593 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13595 * keyboard.c (kbd_buffer_get_event): Read special events also in
13596 batch mode. (Bug#11415)
13598 2012-05-12 Glenn Morris <rgm@gnu.org>

13602 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13604 * lisp.mk (lisp): Add newcomment.elc.
13606 2012-05-12 Glenn Morris <rgm@gnu.org>
13608 * Makefile.in (MKDIR_P): New, set by configure.
13609 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13611 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13613 Remove unused function hourglass_started.
13614 * dispextern.h (hourglass_started):
13615 * w32fns.c (hourglass_started):
13616 * xdisp.c (hourglass_started): Remove.

13620 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13621 Update dependencies.
13623 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13625 * xgselect.c (xg_select): Put maxfds+1 into a var.
13626 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13628 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13630 2012-05-10 Dave Abrahams <dave@boostpro.com>
13632 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13633 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13635 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13637 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13638 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13639 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13640 Initialize xd_registered_buses.
13642 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13644 Untag more efficiently if USE_LSB_TAG.
13645 This is based on a proposal by YAMAMOTO Mitsuharu in
13646 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13647 For an admittedly artificial (nth 8000 longlist) benchmark on
13648 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13649 Emacs's overall text size by 1%.
13650 * lisp.h (XUNTAG): New macro.
13651 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13652 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13653 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13654 * eval.c (Fautoload):
13655 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13656 * frame.h (XFRAME): Use XUNTAG.
13658 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13659 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13660 Remove unportable assumptions about print widths of types like
13662 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13663 intptr_t when converting between pointer and integer, to avoid GCC
13664 warnings about wrong width.
13666 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13668 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13669 stack for each reader_thread, instead of defaulting to 8MB
13670 determined by the linker. This avoids failures in creating
13671 subprocesses on Windows 7, see the discussion in this thread:
13672 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13674 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13676 Fix up display of the *Minibuf-0* buffer in the mini window.
13677 * keyboard.c (read_char): Don't clear the echo area if there's no
13679 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13680 contents of *Minibuf-0*) if there's no message displayed in its stead.
13682 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13684 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13687 2012-05-06 Chong Yidong <cyd@gnu.org>
13689 * lisp.mk (lisp): Update.
13691 2012-05-05 Jim Meyering <meyering@redhat.com>
13693 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13695 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13697 * data.c (PUT_ERROR): New macro.
13698 (syms_of_data): Use it. Add new error type `user-error'.
13699 * undo.c (user_error): New function.
13700 (Fprimitive_undo): Use it.
13701 * print.c (print_error_message): Adjust print style for `user-error'.
13702 * keyboard.c (user_error): New function.
13703 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13705 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13707 Do not limit current-time-string to years 1000..9999.
13708 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13709 (Fcurrent_time_string): Support any year that is supported by the
13710 underlying localtime representation. Don't use asctime, as it
13711 has undefined behavior for years outside the range -999..9999.
13713 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13715 Fix race conditions involving setenv, gmtime, localtime, asctime.
13716 Without this fix, interrupts could mess up code that uses these
13717 nonreentrant functions, since setting TZ invalidates existing
13718 tm_zone or tzname values, and since most of these functions return
13719 pointers to static storage.
13720 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13721 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13722 Grow the critical sections to include not just invoking
13723 localtime/gmtime, but also accessing these functions' results
13724 including their tm_zone values if any, and any related TZ setting.
13725 (format_time_string): Last arg is now struct tm *, not struct tm **,
13726 so that the struct tm is saved in the critical section.
13727 All callers changed. Simplify allocation of initial buffer, partly
13728 motivated by the fact that memory allocation needs to be outside
13729 the critical section.
13731 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13733 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13734 with RESET_INTERVAL.
13736 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13737 Remove duplicated buffer name initialization.
13739 2012-05-02 Jim Meyering <jim@meyering.net>
13741 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13743 * xfns.c (x_window): Use xstrdup (Bug#11375).
13745 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13747 * xdisp.c (pos_visible_p): If already at a newline from the
13748 display string before the 'while' loop, don't walk back the glyphs
13749 from it3.glyph_row. Solves assertion violation when the display
13750 string begins with a newline (egg.el). (Bug#11367)
13752 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13754 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13757 2012-05-01 Glenn Morris <rgm@gnu.org>
13759 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13760 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13761 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13762 All were removed before 23.1.
13764 * dispnew.c: Remove HAVE_LIBNCURSES test;
13765 it is always true on relevant platforms.
13767 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13768 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13770 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13772 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13774 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13775 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13778 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13780 Do not avoid creating empty evaporating overlays (Bug#9642).
13781 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13782 That is, do not delete an evaporating overlay if it becomes
13783 empty after its bounds are adjusted to fit within its buffer.
13784 This fix caused other problems, and I'm reverting it until we get
13785 to the bottom of them.
13787 2012-04-27 Chong Yidong <cyd@gnu.org>
13789 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13791 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13793 * xdisp.c (pos_visible_p): If the window start position is beyond
13794 ZV, start the display from buffer beginning. Prevents assertion
13795 violation in init_iterator when the minibuffer window is scrolled
13796 via the scroll bar.
13798 * window.c (window_scroll_pixel_based): Likewise.
13800 2012-04-27 Chong Yidong <cyd@gnu.org>
13802 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13804 2012-04-27 Glenn Morris <rgm@gnu.org>
13806 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13807 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13809 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13811 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13812 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13814 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13816 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13817 display element, check also the underlying string or buffer
13818 character. (Bug#11341)
13820 * w32menu.c: Include w32heap.h.
13821 (add_menu_item): If the call to AppendMenuW (via
13822 unicode_append_menu) fails, disable Unicode menus only if we are
13823 running on Windows 9X/Me.
13825 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13827 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13828 (xgetint): Add missing shift for LSB tags.
13830 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13832 * keyboard.c (read_char): Don't wipe echo area for select window
13833 events: These might get delayed via `mouse-autoselect-window'
13836 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13838 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13839 manipulation of :loaded-from data.
13841 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13843 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13844 now a cons (bug#11311).
13846 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13848 Do not create empty overlays with the evaporate property (Bug#9642).
13849 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13850 if it becomes empty after its bounds are adjusted to fit within
13851 its buffer. Without this fix, in a nonempty buffer (let ((o
13852 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13853 yields an empty overlay that has the evaporate property, which is
13854 not supposed to happen.
13856 Fix minor GTK3 problems found by static checking.
13857 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

13865 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
13866 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
13867 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)

13874 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13876 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13877 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13878 (__malloc_size_t, __malloc_ptrdiff_t):
13879 Remove. All uses removed, replaced by the definiens if needed,
13880 since we can assume C89 or better now.
13881 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

13888 (special_realloc, _realloc_internal_nolock, _realloc_internal)
13889 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13890 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13891 Define using prototypes, not old style.
13892 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):

13956 * alloc.c: Handle unusual debugging option combinations.
13957 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13958 since the two debugging options are incompatible.
13959 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
13961 (mem_init, mem_insert, mem_insert_fixup):
13962 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

13972 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13973 Use Emacs indenting style more consistently. Avoid some casts.

14013 row, return zero immediately.
14014 (try_cursor_movement): If inside continuation line, don't back up
14015 farther than the first row after the header line, if any.
14016 Don't consider the header-line row as "partially visible", even if

14055 New extern decls, to avoid calling undeclared functions.
14056 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14057 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined

14059 (NEED_MEM_INSERT): New macro.
14060 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
14061 Remove one incorrect comment and fix another.

14065 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
14066 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
14067 (r_alloc_sbrk): Now static.
14069 Improve ralloc.c interface checking.
14070 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
14071 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

14097 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
14098 * s/netbsd.h, s/sol2-6.h:
14099 Remove definition of GC_MARK_STACK, since the default now works.
14100 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14101 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14102 no longer the default.
14103 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14105 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
14107 * lread.c (lisp_file_lexically_bound_p):

14118 one screen (Bug#10962).
14120 2012-04-13 Ken Brown <kbrown@cornell.edu>
14122 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
14124 2012-04-13 Reuben Thomas <rrt@sc3d.org>
14126 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14128 2012-04-11 Daniel Colascione <dancol@dancol.org>
14130 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14131 against is gone. It's better to use vfork now so that when Cygwin
14132 gains a new, working vfork, we use it automatically (bug#10398).
14134 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
14136 * window.c (save_window_save): Obey window-point-insertion-type.

14149 (force_quit_count): New var.
14150 (handle_interrupt): Use it.
14152 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
14154 * w32.c (w32_delayed_load): Record the full path of the library
14155 being loaded (bug#10424).
14157 2012-04-09 Glenn Morris <rgm@gnu.org>
14159 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14160 not just in the obarray, before snarfing them. (Bug#11036)
14162 * Makefile.in ($(leimdir)/leim-list.el):
14163 Pass EMACS rather than BUILT_EMACS.
14165 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
14167 * process.c (make_process):
14168 * process.h: Add integer `gnutls_handshakes_tried' member to
14171 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
14172 Add convenience `GNUTLS_LOG2i' macro.
14174 * gnutls.c (gnutls_log_function2i): Convenience log function.
14175 (emacs_gnutls_read): Use new log functions,
14176 `gnutls_handshakes_tried' process member, and
14177 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14178 attempts per process (connection).
14180 2012-04-09 Chong Yidong <cyd@gnu.org>
14182 * eval.c (Fuser_variable_p, user_variable_p_eh)
14183 (lisp_indirect_variable): Functions deleted.
14184 (Fdefvar): Caller changed.
14186 * callint.c (Finteractive, Fcall_interactively):
14187 * minibuf.c (Fread_variable): Callers changed.
14189 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14191 * xdisp.c (set_cursor_from_row): If the display string appears in
14192 the buffer at position that is closer to point than the position
14193 after the display string, display the cursor on the first glyph of
14194 the display string. Fixes cursor display when a 'display' text
14195 property immediately follows invisible text. (Bug#11094)
14197 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14199 composite.c: use 'double' consistently
14200 * composite.c (get_composition_id): Use 'double' consistently
14201 instead of converting 'float' to 'double' and vice versa; this is
14202 easier to understand and avoids a GCC warning.
14204 2012-04-09 Glenn Morris <rgm@gnu.org>
14206 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14207 preparation for dumping it with emacs. (Bug#4789)
14208 (leimdir): New variable.
14209 ($(leimdir)/leim-list.el): New rule.
14210 (emacs$(EXEEXT)): Depend on leim-list.el.
14212 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
14213 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
14214 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
14216 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>

14224 Remove unused local variable.
14226 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
14228 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14229 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14230 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14231 objects, as mark_maybe_pointer will catch them otherwise.
14232 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
14233 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
14235 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
14237 Fix typo that broke non-Windows builds.
14238 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
14240 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14242 Support building on MS-Windows with libxml2.
14244 * makefile.w32-in (OBJ2): Add xml.$(O).
14245 (GLOBAL_SOURCES): Add xml.c.
14246 ($(BLD)/xml.$(O)): New dependency list.
14248 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14249 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14250 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14251 [!WINDOWSNT]: New macros.
14252 (init_libxml2_functions, libxml2_loaded_p): New functions.
14253 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14254 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14255 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14256 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14258 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14259 Call init_libxml2_functions before calling libxml2 functions.
14260 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14262 * emacs.c: Don't include libxml/parser.h.
14263 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14264 xmlCleanupParser directly.
14266 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14268 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14270 * indent.c (Fvertical_motion): If there is a display string at
14271 point, use it.vpos to compute how many lines to backtrack after
14272 move_it_to point. (Bug#11133)
14274 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14276 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14277 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14278 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14279 macros related to unification of CJK characters. For the details,
14280 see the discussion following the message here:
14281 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14283 2012-04-04 Chong Yidong <cyd@gnu.org>
14285 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14287 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14289 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
14290 instead of alloca. (Bug#11138)
14292 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
14294 * w32menu.c (is_simple_dialog): Properly check lisp types.
14297 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14299 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14300 position we get to after a call to move_it_to fails the
14301 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14302 only if we wind up in a string from display property. (Bug#11063)
14304 * window.c (Fdelete_other_windows_internal): Invalidate the row
14305 and column information about mouse highlight, so that redisplay
14306 restores it after reallocating the glyph matrices. (Bug#7464)
14308 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14309 string comes from a `display' text property, use the buffer
14310 position of that property as if we actually saw that position in
14312 (move_it_by_lines): Remove the assertion that
14313 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14314 violated when there's a before-string at the beginning of a line.
14317 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14319 * xdisp.c (append_space_for_newline): If the default face was
14320 remapped, use the remapped face for the appended newline.
14321 (extend_face_to_end_of_line): Use the remapped default face for
14322 extending the face to the end of the line.
14323 (display_line): Call extend_face_to_end_of_line when the default
14324 face was remapped. (Bug#11068)
14326 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14328 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14330 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14332 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
14334 2012-03-27 Glenn Morris <rgm@gnu.org>
14336 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
14339 2012-03-26 Kenichi Handa <handa@m17n.org>
14341 * dispextern.h (struct glyph): Fix previous change. Change the
14342 bit length of glyphless.ch to 25 (Bug#11082).
14344 2012-03-26 Chong Yidong <cyd@gnu.org>
14346 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14347 (command_loop_1): Use it; inhibit selection update for
14348 handle-select-window too (Bug#8996).
14350 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
14352 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14354 2012-03-25 Kenichi Handa <handa@m17n.org>
14356 * dispextern.h (struct glyph): Change the bit length of
14357 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14359 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14361 * s/ms-w32.h (tzname): Include time.h before redirecting to
14362 _tzname. Fixes the MSVC build. (Bug#9960)
14364 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
14366 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14369 * xterm.c (XTread_socket): Only modify handling_signal if
14370 !SYNC_INPUT. (Bug#11080)
14372 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14374 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14375 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14376 when fetching a multibyte character consumes more bytes than
14377 CHAR_BYTES returns, due to unification of CJK characters in
14378 string_char. (Bug#11073)
14380 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14382 * process.c (wait_reading_process_output): Handle pty disconnect
14383 by refraining from sending oneself a SIGCHLD (bug#10933).
14385 2012-03-22 Chong Yidong <cyd@gnu.org>
14387 * dispextern.h (struct it): New member string_from_prefix_prop_p.
14389 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
14390 Mark string as coming from a prefix property.
14391 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14392 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14394 2012-03-21 Chong Yidong <cyd@gnu.org>
14396 * xfaces.c (Vface_remapping_alist): Doc fix.
14398 2012-03-20 Eli Zaretskii <eliz@gnu.org>
14400 * w32proc.c (Fw32_set_console_codepage)
14401 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
14404 2012-03-20 Chong Yidong <cyd@gnu.org>
14406 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
14407 to reflect default non-nil value of redisplay-dont-pause.
14409 2012-03-19 Kenichi Handa <handa@m17n.org>
14411 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
14412 it fit in a valid range (Bug#11003).
14414 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14416 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14417 that is not from display property, accept the row as a "cursor
14418 row" if one of the string's character has a non-nil `cursor'
14419 property. Fixes cursor positioning when there are newlines in
14420 overlay strings, e.g. in icomplete.el. (Bug#11035)
14422 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14424 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14426 2012-03-12 Chong Yidong <cyd@gnu.org>
14428 * eval.c (inhibit_lisp_code): Rename from
14429 inhibit_window_configuration_change_hook; move from window.c.
14431 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14432 * window.c (run_window_configuration_change_hook)
14433 (syms_of_window): Callers changed.
14435 2012-03-11 Chong Yidong <cyd@gnu.org>
14437 * keymap.c (Fkey_description): Doc fix (Bug#9700).
14439 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
14441 2012-03-10 Chong Yidong <cyd@gnu.org>
14443 * frame.c (other_visible_frames): Don't assume the selected frame
14444 is visible (Bug#10955).
14446 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
14448 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14450 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14452 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14453 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14456 2012-03-03 Glenn Morris <rgm@gnu.org>
14458 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14460 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14462 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14463 position past the first glyph_row that ends at ZV. (Bug#10902)
14464 (redisplay_window, next_element_from_string): Fix typos in
14466 (redisplay_window): Pass to move_it_vertically the margin in
14467 pixels, not in screen lines.
14469 2012-03-02 Glenn Morris <rgm@gnu.org>
14471 * buffer.c (buffer-list-update-hook): Doc fix.
14473 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14475 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14476 push_it before setting up the iterator for the first overlay
14477 string, even if we have an empty string loaded.
14478 (next_overlay_string): If there's an empty string on the iterator
14479 stack, pop the stack. (Bug#10903)
14481 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14483 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14484 Suggested by Stefan Monnier in
14485 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14486 * alloc.c (widen_to_Lisp_Object): New static function.
14487 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14488 and widening them to Lisp_Objects. This would work even if
14489 USE_LSB_TAG is defined and wide integers are used, which might
14490 happen in a future version of Emacs.
14492 2012-02-25 Chong Yidong <cyd@gnu.org>
14494 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14497 * xselect.c (Fx_selection_exists_p): Doc fix.
14498 (x_clipboard_manager_save_all): Print an informative message
14499 before saving to clipboard manager.
14501 2012-02-24 Chong Yidong <cyd@gnu.org>
14503 * keyboard.c (process_special_events): Handle all X selection
14504 requests in kbd_buffer, not just the next one (Bug#8869).
14506 2012-02-23 Chong Yidong <cyd@gnu.org>
14508 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14509 call when setting menu-bar-lines and tool-bar-lines parameters.
14510 (unwind_create_frame_1): New helper function.
14512 * window.c (inhibit_window_configuration_change_hook): New var.
14513 (run_window_configuration_change_hook): Obey it.
14514 (syms_of_window): Initialize it.
14516 2012-02-22 Chong Yidong <cyd@gnu.org>
14518 * xterm.c (x_draw_image_relief): Add missing type check for
14519 Vtool_bar_button_margin (Bug#10743).
14521 2012-02-21 Chong Yidong <cyd@gnu.org>
14523 * fileio.c (Vfile_name_handler_alist): Doc fix.
14525 * buffer.c (Fget_file_buffer): Protect against invalid file
14526 handler return value.
14528 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
14530 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
14531 when computing $valmask.
14533 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14534 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14535 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14536 It's useless in that case, and it can cause problems on hosts
14537 that allocate halves of EMACS_INT values separately.
14538 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14539 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14540 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14541 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14542 it avoids undefined behavior on hosts where shifting right by more
14543 than the word width has undefined behavior.
14545 2012-02-19 Chong Yidong <cyd@gnu.org>
14547 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14548 (Funhandled_file_name_directory, Ffile_name_as_directory)
14549 (Fdirectory_file_name, Fexpand_file_name)
14550 (Fsubstitute_in_file_name): Protect against invalid file handler
14551 return values (Bug#10845).
14553 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14555 * .gdbinit (pitx): Fix incorrect references to fields of the
14558 2012-02-17 Chong Yidong <cyd@gnu.org>
14560 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
14562 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
14564 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
14565 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14567 2012-02-15 Chong Yidong <cyd@gnu.org>
14569 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14570 marked as special. Also, starting docstrings with * is obsolete.
14572 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
14574 * gnutls.c (emacs_gnutls_write): Fix last change.
14576 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
14578 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
14581 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
14583 * keymap.c (Fsingle_key_description): Handle char ranges.
14585 2012-02-12 Chong Yidong <cyd@gnu.org>
14587 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14588 as that creates a dangerous corner case.
14590 * window.c (Fdelete_window_internal): Invalidate the mouse
14591 highlight (Bug#9904).

15153 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
15155 * keyboard.c (interrupt_signal): Don't call kill-emacs when

15158 2011-11-30 Eli Zaretskii <eliz@gnu.org>
15160 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
15161 verifies glyph row's hash code--we have just reallocated the
15162 glyphs, so their contents can be complete garbage. (Bug#10164)

15208 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
15209 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in

15241 (start_display): Don't move to the next line if the display should
15242 start at a newline that is part of a display vector or an overlay

15322 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
15323 Otherwise, valgrind does not work on some platforms.

15326 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15327 is set, removing the need for VIRT_ADDRESS_VARIES.
15328 (PURE_P): Use a more-efficient implementation that needs just one
15329 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the

15335 consistency with the new puresize.h.
15336 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
15337 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

15343 (erase_phys_cursor, update_window_cursor, show_mouse_face)
15344 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
15345 behave as if the cursor position were at the window margin.
15347 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15348 and the cursor position is out of bounds, behave as if the cursor
15349 position were at the window margin. (Bug#10075)
15351 2011-11-18 Chong Yidong <cyd@gnu.org>
15353 * window.c (Fwindow_combination_limit): Make first argument

15372 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
15374 * xdisp.c (row_hash): New function, body extracted from
15375 compute_line_metrics.
15376 (compute_line_metrics): Call row_hash, instead of computing the
15379 * dispnew.c (verify_row_hash): Call row_hash for computing the
15380 hash code of a row, instead of duplicating code from xdisp.c.
15382 * dispextern.h (row_hash): Add prototype.
15384 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
15386 * frame.c (delete_frame): Don't delete the terminal when the last

15435 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
15436 with user-defined heap size. Bump the default size of the temacs

15440 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15441 current_matrix and desired_matrix. (Bug#9990)
15442 (verify_row_hash) [XASSERTS]: New function.

15487 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
15489 Avoid some portability problems by eschewing 'extern inline' functions.
15490 The trivial performance wins aren't worth the portability hassles; see
15491 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15493 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

15542 This is also needed for porting to any host where GC_MARK_STACK is
15543 not GC_MAKE_GCPROS_NOOPS.
15544 (which_symbols): Use it.
15546 2011-11-07 Kenichi Handa <handa@m17n.org>

15559 * xmenu.c (cleanup_widget_value_tree): New function.
15560 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15561 calling free_menubar_widget_value_tree directly (Bug#9830).
15563 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
15565 Fix some portability problems with 'inline'.
15566 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
15567 (window_box_width, window_box_left, window_box_left_offset)
15568 (window_box_right, window_box_right_offset): Declare extern.
15569 Otherwise, these inline functions do not conform to C99 and
15570 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15571 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15572 * intervals.c (adjust_intervals_for_insertion)
15573 (adjust_intervals_for_deletion): Now extern, because otherwise the
15574 extern inline functions 'offset_intervals' couldn't refer to it.
15575 (static_offset_intervals): Remove.
15576 (offset_intervals): Rewrite using the old contents of
15577 static_offset_intervals. The old version didn't conform to C99
15578 because an extern inline function contained a reference to an
15579 identifier with static linkage.
15581 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
15583 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

15603 argument, since it makes no sense to pass a live window and for
15604 consistency with window-child.

15645 official. Move initialization of image_cache_refcount and
15646 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15686 previous/next-single-property-change returns nil, treat that as
15687 the beginning or the end of the buffer. (Bug#9955)
15689 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
15691 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

15814 (w32font_open_internal, compute_metrics):
15815 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15816 instead of calling the "wide" APIs directly.
15818 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15820 * w32.h (syms_of_w32font): Add prototype.
15822 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

15826 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15827 (Fmove_to_window_line): Doc fix.
15829 2011-10-27 Chong Yidong <cyd@gnu.org>
15831 * process.c (make_process): Set gnutls_state to NULL.
15833 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15834 non-NULL, regardless of GNUTLS_INITSTAGE.

15883 (bidi_resolve_weak): Don't enter the expensive loop if the current
15884 position is before next_en_pos. Record the bidi type of the first
15885 non-ET, non-BN character we find, in addition to its position.
15886 (bidi_level_of_next_char): Invalidate next_en_type when
15887 next_en_pos is over-stepped.
15889 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15891 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15892 * editfns.c: Rewrite current-time-zone so that it invokes
15893 the equivalent of (format-time-string "%Z") to get the time zone name.
15894 This fixes a bug when the time zone name contains characters that
15895 need converting from the system time locale to Emacs internal format.
15896 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15897 that patch fixed format-time-string to do the conversion, but
15898 I forgot to fix current-time-zone.
15899 (format_time_string): New function, containing most of
15900 what Fformat_time_string used to contain.
15901 (Fformat_time_string): Rewrite in terms of format_time_string.
15902 This doesn't change this function's behavior.
15903 (current-time-zone): Rewrite to use format_time_string.
15904 This fixes the bug reported by Michael Schierl in
15905 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15906 Jason Rumney's 2007-06-07 change worked around this bug, but
15908 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15910 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15912 * xdisp.c (start_display): If the character at POS is displayed
15913 via a display vector, reset IT->current.dpvec_index to zero.
15914 (try_window_reusing_current_matrix): If a line ends in a display
15915 vector or the next line starts in a display vector, continue
15916 redrawing the window even though the character position of
15917 start_row was reached.
15920 2011-10-18 Chong Yidong <cyd@gnu.org>
15922 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15923 with nobreak-char-display too.
15925 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15927 Fix part 3 of bug#9771.
15928 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15929 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15930 non-neutral characters if the current character is a paragraph
15931 separator (a.k.a. Newline). This avoids running the same
15932 expensive loop twice, once when we consume the preceding newline
15933 and the other time when the line actually needs to be displayed.
15934 Avoid the loop when we see neutrals on the base embedding level
15935 following a character whose directionality is the same as the
15936 paragraph's. This avoids running the expensive loop when a line
15937 ends in a long sequence of neutrals, like control characters.
15938 Add assertion against STRONG_AL type. Slightly rearrange code
15939 that determines the type of a neutral given the first non-neutral
15941 (bidi_level_of_next_char): Set next_en_pos to zero when
15942 invalidating its info.
15944 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15946 * xdisp.c (push_display_prop): Determine whether to record string
15947 or buffer position by IT->string, not by IT->method. Allow
15948 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15949 (move_it_vertically_backward): Don't look for character position
15950 immediately after the newline when in a continuation line.
15953 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15955 * window.c (coordinates_in_window): Rewrite and delabelize
15956 vertical border check. (Bug#5357) (Bug#9618)

15960 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15961 errors in XSetWindowBorder (bug#9310).
15963 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15965 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15966 avoid crash when xmalloc overrun checking is enabled.
15968 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15970 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15971 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15972 cursor motion with <left> and <right> arrow keys.
15974 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15975 some callers set that themselves.
15977 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15979 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15980 display string and the previous row comes from the same string and
15981 is empty. (Bug#9739) (Bug#9738)
15983 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>

15989 * bidi.c (bidi_level_of_next_char):
15990 * xdisp.c (get_visually_first_element): Remove old incorrect
15991 comments regarding the Unicode Line Separator character.
15993 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15995 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15997 * alloc.c (Fgc_status): Do not access beyond zombies array
15998 boundary if nzombies > MAX_ZOMBIES.
15999 * alloc.c (dump_zombies): Add missing format specifier.
16001 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
16003 * xdisp.c (set_cursor_from_row): Simplify conditionals,
16004 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16006 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16007 Some packages use them to denote characters with modifiers.
16009 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16011 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16012 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16013 matching a pp-number. Rename parameter var to var1.
16015 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16017 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16019 2011-10-08 Glenn Morris <rgm@gnu.org>
16021 * callint.c (Fcall_interactively): Give a more explicit error for the
16022 'c' case with a non-character input. (Bug#8479)
16024 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16026 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16028 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16029 lines that are hscrolled on the left.
16031 * dispnew.c (buffer_posn_from_coords): Account for a possible
16032 presence of header-line. (Bug#4426)
16034 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16036 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16037 Don't advertise functionality which we discourage or doesn't work.
16039 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16041 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16042 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16043 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16044 this makes Emacs dump core during garbage collection on rare
16045 occasions. sizeof is obviously inferior to offsetof here, so
16046 stick with offsetof.
16047 (GC_POINTER_ALIGNMENT): New macro.
16048 (mark_memory): Omit 3rd (offset) arg; caller changed.
16049 Don't assume EMACS_INT alignment is the same as pointer alignment.
16051 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16053 * keyboard.c (read_key_sequence_remapped): New var.
16054 (read_key_sequence): Compute remapping in the right buffer.
16055 (command_loop_1): Use read_key_sequence's remapping directly.
16057 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16059 * dired.c (file_name_completion): Don't expand file name.
16060 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16061 before checking file name handler.
16063 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16064 they've been requested explicitly (bug#9591).
16066 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16068 * keymap.c (Fsingle_key_description): Use make_specified_string
16069 instead of build_string to build string from push_key_description.
16072 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16074 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16075 This fixes a Y2038 bug on 64-bit hosts.
16076 * buffer.c (reset_buffer):
16077 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16078 (Fclear_buffer_auto_save_failure):
16079 Use 0, not -1, to represent an unset failure time, since time_t
16080 might not be signed.
16082 Remove dependency on glibc malloc internals.
16083 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16084 Move back here from lisp.h, but with their new implementations.
16085 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16086 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16087 * charset.c (charset_table_init): New static var.
16088 (syms_of_charset): Use it instead of xmalloc. This removes a
16089 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16090 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16091 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16092 Move back to alloc.c.
16093 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16094 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16096 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16098 * nsterm.m (windowDidResize): Call x_set_window_size only when
16099 ns_in_resize is true. Otherwise set pixelwidth/height and
16100 call change_frame_size (Bug#9628).
16102 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16104 Port --enable-checking=all to Fedora 14 x86-64.
16105 * charset.c (syms_of_charset): Also account for glibc malloc's
16106 internal overhead when calculating the initial malloc maximum.
16108 Port --enable-checking=all to Fedora 14 x86.
16109 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16111 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16112 (overrun_check_realloc, overrun_check_free):
16113 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16114 That way, xmalloc returns a properly-aligned pointer even if
16115 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16116 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16117 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16118 into account when calculating the initial malloc maximum.
16119 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16120 Move here from alloc.c, so that charset.c can use it too.
16121 Properly align; the old code wasn't right for common 32-bit hosts
16122 when configured with --enable-checking=all.
16123 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16124 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16126 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16128 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16131 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16133 * xdisp.c (compute_display_string_end): If there's no display
16134 string at CHARPOS, return -1.
16136 * bidi.c (bidi_fetch_char): When compute_display_string_end
16137 returns a negative value, treat the character as a normal
16138 character not covered by a display string. (Bug#9624)
16140 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16142 * lread.c (Fread_from_string): Fix typo in docstring.
16144 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16146 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16147 newline, reseat the iterator instead of bidi-iterating there one
16148 character at a time. (Bug#9610)
16149 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16150 TO_CHARPOS if the bidi iterator is at base embedding level.
16152 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16154 * lread.c (readevalloop): Use correct code for NBSP.
16155 (read1): Likewise. (Bug#9608)
16157 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16159 * dbusbind.c (Fdbus_register_signal): When service is not
16160 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16162 2011-09-25 Glenn Morris <rgm@gnu.org>
16164 * buffer.c (truncate-lines): Doc fix.
16166 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16168 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16169 (Fset_window_next_buffers): Doc fix.
16171 2011-09-24 Glenn Morris <rgm@gnu.org>
16173 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16175 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16177 Fix minor problems found by static checking.
16178 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16179 * indent.c (Fvertical_motion): Fix == vs = typo.
16181 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16183 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16184 Default value is now t. Doc fix.
16186 * indent.c (Fvertical_motion): Compute and apply the overshoot
16187 logic when moving up, not only when moving down. Fix the
16188 confusing name and values of the it_overshoot_expected variable;
16189 logic changes accordingly. (Bug#9254) (Bug#9549)
16191 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16192 CHARPOS is covered by a display string which includes newlines.
16193 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16194 is covered by a display string with embedded newlines.
16196 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16198 * dbusbind.c (Fdbus_register_signal): Add match rule to
16199 Vdbus_registered_objects_table. (Bug#9581)
16200 (Fdbus_register_method, Vdbus_registered_objects_table):
16203 2011-09-24 Jim Meyering <meyering@redhat.com>
16205 do not ignore write error for any output size
16206 The previous change was incomplete.
16207 While it makes emacs --batch detect the vast majority of stdout
16208 write failures, errors were still ignored whenever the output size is
16209 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16210 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16211 && echo FAIL: ignored write error
16212 FAIL: ignored write error
16213 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16214 && echo FAIL: ignored write error
16215 FAIL: ignored write error
16216 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16218 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16220 * emacs.c (Fkill_emacs): In noninteractive mode exit
16221 non-successfully if a write error occurred on stdout. (Bug#9574)
16223 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16225 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16228 * dispextern.h (struct it): Update the comment documenting what
16231 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16233 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16234 a display string, extend search for cursor position to end of row.
16235 (find_row_edges): If the row ends in a newline from a display
16236 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16237 Handle the case of a display string with multiple newlines.
16238 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16239 non-empty line. Fixes confusing cursor motion with arrow keys at
16240 the beginning of a line that starts with whitespace.
16242 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16244 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16247 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16249 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16250 boolean (Bug#9154).
16252 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16254 * xdisp.c (display_line): Record maximum and minimum buffer
16255 positions even if no glyphs were produced (e.g., by a zero-width
16256 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16257 buffer positions that will be removed from the glyph row because
16259 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16260 column is beyond frame width: don't subtract 1 "pixel" when
16261 computing width of the stretch.
16262 (reseat_at_next_visible_line_start): Undo the change made on
16263 2011-09-17 that saved paragraph information and restored it after
16264 the call to `reseat'. (Bug#9545)
16266 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16268 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16269 and turn window cursor on if cleared (Bug#9415).
16271 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16273 * search.c (boyer_moore): Take unibyte characters from pattern
16274 literally. (Bug#9458)
16276 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16278 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16280 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16282 Fix minor problem found by static checking.
16283 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16284 initialized, to pacify gcc -Wuninitialized.
16286 * fileio.c: Report proper errno when syscall falls.
16287 (Finsert_file_contents): Save and restore errno,
16288 so that report_file_error outputs the correct diagnostic.
16289 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16291 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16293 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16295 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16297 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16298 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16300 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16302 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16303 about the current paragraph and restore it after the call to reseat.
16305 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16306 (bidi_find_paragraph_start): Search back for paragraph beginning
16307 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16308 (bidi_move_to_visually_next): Only trigger paragraph-related
16309 computations when the last character is a newline or at EOB, not
16310 just any NEUTRAL_B. (Bug#9470)
16312 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16313 truncated lines if point is covered by a display string. (Bug#9524)
16315 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16317 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16318 (cons_to_x_long): New function.
16319 (lisp_data_to_selection_data): Use it. Correct the test for
16320 short-versus-long data; it was negated. Break out of vector
16321 loop, for efficiency, when a long datum is discovered.
16323 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16325 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16327 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16329 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16330 GCC PR/17406) by declaring this function with external scope.
16332 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16334 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16335 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16337 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16339 * editfns.c (Fformat): Correctly handle text properties on "%%".
16341 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16343 * xterm.c (x_draw_composite_glyph_string_foreground):
16344 * w32term.c (x_draw_composite_glyph_string_foreground):
16345 * term.c (encode_terminal_code):
16346 * composite.c (composition_update_it, get_composition_id):
16347 * xdisp.c (get_next_display_element)
16348 (fill_composite_glyph_string): Add comments about special meaning
16349 of TAB characters in a composition.
16351 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16353 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16354 This occurs when processing a multibyte format.
16355 Problem reported by Wolfgang Jenker.
16357 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16359 * xdisp.c (try_cursor_movement): Only check for exact match if
16360 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16362 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16364 Remove unused external symbols.
16365 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16366 * xdisp.c (calc_pixel_width_or_height): Now static.
16367 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16368 * indent.c (check_display_width):
16369 * w32term.c: Fix comment to match code.
16370 * xterm.c, xterm.h (x_catching_errors): Remove.
16372 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16374 * xselect.c: Use signed conversions more consistently (Bug#9498).
16375 (selection_data_to_lisp_data): Assume incoming selection data are
16376 signed integers, not unsigned. This is to be consistent with
16377 outgoing selection data, which was modified to use signed integers
16378 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16379 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16380 expects long, not unsigned long.
16382 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16384 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16385 computation of loop end. Reported by Johan Bockgård
16388 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16390 * frame.c (Fother_visible_frames_p): Function deleted.
16392 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16394 * indent.c (compute_motion): Process display vector front to back
16395 rather than the other way around. (Bug#2496)
16397 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16399 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16401 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16403 * minibuf.c (Fread_from_minibuffer): Doc fix.
16405 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16407 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16408 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16410 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16412 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16413 value for non-existent files.
16415 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16417 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16418 set its "size" to -1. This will set the modtime_size field of
16419 the corresponding buffer to -1, which is what
16420 verify-visited-file-modtime expects for files that do not exist.
16423 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16425 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16427 * lisp.h: ... from here. push_key_description is no longer
16428 defined in keyboard.c, so its declaration should not be in
16429 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16430 logically belongs with push_key_description.
16432 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16434 * buffer.h: Include <sys/types.h> instead of <time.h>.
16435 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16436 Problem reported by Herbert J. Skuhra.
16438 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16440 * xml.c (parse_region): Make the parsing work for
16441 non-comment-starting XML files again (bug#9144).
16443 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16445 * image.c (gif_load): Fix calculation of bottom and right corner.
16448 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16450 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16451 redisplay in small windows.
16453 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16455 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16457 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16459 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16460 Operate on live windows only.
16462 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16464 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16466 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16468 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16469 only under bidi iteration.
16471 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16473 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16475 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16477 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16478 Without this fix, the command to link temacs failed due to an
16479 undefined symbol __builtin_isnan. This is because
16480 /usr/include/iso/math_c99.h #defines isnan(x) to
16481 __builtin_isnan(x), but the bundled gcc, which identifies itself
16482 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16484 * floatfns.c (isnan): #undef, and then #define to a clone of
16486 (Fisnan): Always define, since it's always available now.
16487 (syms_of_floatfns): Always define isnan at the Lisp level.
16489 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16491 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16493 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16495 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16496 The previous code assumed that file offsets (off_t values) fit in
16497 EMACS_INT variables, which is not true on typical 32-bit hosts.
16498 The code messed up by falsely reporting buffer overflow in cases
16499 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16500 when "big" contains more than 2**29 bytes, even though this
16501 inserts just one byte and does not overflow the buffer.
16502 (Finsert_file_contents): Store file offsets as off_t
16503 values, not as EMACS_INT values. Check for overflow when
16504 converting between EMACS_INT and off_t. When checking for
16505 buffer overflow or for overlap, take the offsets into account.
16506 Don't use EMACS_INT for small values where int suffices.
16507 When checking for overlap, fix a typo: ZV was used where
16508 ZV_BYTE was intended.
16509 (Fwrite_region): Don't assume off_t fits into 'long'.
16510 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16512 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16514 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16516 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16518 sprintf-related integer and memory overflow issues (Bug#9412).
16520 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16521 (esprintf, exprintf, evxprintf): New functions.
16522 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16523 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16524 (modify_event_symbol): Do not assume that the length of
16525 name_alist_or_stem is safe to alloca and fits in int.
16526 (Fexecute_extended_command): Likewise for function name and binding.
16527 (Frecursion_depth): Wrap around reliably on integer overflow.
16528 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16529 since some callers pass EMACS_INT values.
16530 (Fsingle_key_description): Don't crash if symbol name contains more
16531 than MAX_ALLOCA bytes.
16532 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16533 (get_minibuffer): Arg is now EMACS_INT, not int.
16534 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16535 (esprintf, exprintf, evxprintf): New decls.
16536 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16538 * dbusbind.c (signature_cat): New function.
16539 (xd_signature, Fdbus_register_signal):
16540 Do not overrun buffer; instead, report string overflow.
16542 * dispnew.c (add_window_display_history): Don't overrun buffer.
16543 Truncate instead; this is OK since it's just a log.
16545 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16546 even if the time zone offset is outlandishly large.
16547 Don't mishandle offset == INT_MIN.
16549 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16550 when creating daemon; the previous buffer-overflow check was incorrect.
16552 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16553 which has the guts of the old verror function.
16555 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16556 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16558 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16559 (font_unparse_xlfd): Don't blindly alloca long strings.
16560 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16561 fits in int, when using sprintf. Use single snprintf to count
16562 length of string rather than counting it via multiple sprintfs;
16563 that's simpler and more reliable.
16564 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16565 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16566 sprintf, in case result does not fit in int.
16568 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16569 (fontset_from_font): Print it.
16571 * frame.c (tty_frame_count): Now printmax_t, not int.
16572 (make_terminal_frame, set_term_frame_name): Print it.
16573 (x_report_frame_params): In X, window IDs are unsigned long,
16574 not signed long, so print them as unsigned.
16575 (validate_x_resource_name): Check for implausibly long names,
16576 and don't assume name length fits in 'int'.
16577 (x_get_resource_string): Don't blindly alloca invocation name;
16578 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16581 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16582 (xg_check_special_colors, xg_set_geometry):
16583 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16585 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16586 Use esprintf, not sprintf, in case result does not fit in int.
16588 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16589 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16590 it as a large positive number.
16591 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16592 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16594 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16595 in case result does not fit in int.
16597 * print.c (float_to_string): Detect width overflow more reliably.
16598 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16599 buffer overrun. Don't assume list length fits in 'int'. Treat
16600 print length of 0 as 0, not as infinity; to be consistent with other
16601 uses of print length in this function. Don't overflow print length
16602 index. Don't assume hash table size fits in 'long', or that
16603 vectorlike size fits in 'unsigned long'.
16605 * process.c (make_process): Use printmax_t, not int, to format
16606 process-name gensyms.
16608 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16610 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16611 to avoid potential buffer overrun.
16613 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16614 if X resource line is longer than 512 bytes.
16616 * xfns.c (x_window): Make sprintf buffer a bit bigger
16617 to avoid potential buffer overrun.
16619 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16621 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16623 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16625 Integer overflow fixes for scrolling, etc.
16626 Without these, Emacs silently mishandles large integers sometimes.
16627 For example, "C-u 4294967297 M-x recenter" was treated as if
16628 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16630 * xdisp.c (try_window_id): Check Emacs fixnum range before
16631 converting to 'int'.
16633 * window.c (window_scroll_line_based, Frecenter):
16634 Check that an Emacs fixnum is in range before assigning it to 'int'.
16635 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16636 values converted from Emacs fixnums.
16637 (Frecenter): Don't wrap around a line count if it is out of 'int'
16638 range; instead, treat it as an extreme value.
16639 (Fset_window_configuration, compare_window_configurations):
16640 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16642 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16643 that can exceed INT_MAX. Check that EMACS_INT value is in range
16644 before assigning it to the (possibly-narrower) index.
16645 (match_limit): Don't assume that a fixnum can fit in 'int'.
16647 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16650 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16651 (Fvertical_motion): Don't wrap around LINES values that don't fit
16652 in 'int'. Instead, treat them as extreme values. This is good
16653 enough for windows, which can't have more than INT_MAX lines anyway.
16655 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16657 * Require libxml/parser.h to avoid compilation warning.
16659 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16661 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16662 since this reportedly can destroy thread storage.
16664 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16666 * syntax.c (find_defun_start): Update all cache variables if
16667 exiting early (Bug#9401).
16669 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16671 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16673 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16674 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16675 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16677 * term.c (tty_append_glyph): New function.
16678 (produce_stretch_glyph): Static function and its prototype deleted.
16680 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16683 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16685 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16686 when checking :margin (Bug#9390).
16687 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16688 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16689 so that the name doesn't mislead. All uses changed.
16691 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16693 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16696 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16698 * xdisp.c (move_it_to): Don't bail out early when reaching
16699 position beyond to_charpos, if we are scanning backwards.
16700 (move_it_vertically_backward): When DY == 0, make sure we get to
16701 the first character in the line after the newline.
16703 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16705 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16706 (ccl_driver): Do not generate an out-of-range pointer.
16707 (Fccl_execute_on_string): Remove unnecessary check for
16708 integer overflow, noted by Stefan Monnier in
16709 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16710 Remove a FIXME that didn't need fixing.
16711 Simplify the newly-introduced buffer reallocation code.
16713 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16715 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16717 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16719 Integer and memory overflow issues (Bug#9196).
16721 * doc.c (get_doc_string): Rework so that
16722 get_doc_string_buffer_size is the actual buffer size, rather than
16723 being 1 less than the actual buffer size; this makes xpalloc more
16726 * image.c (x_allocate_bitmap_record, cache_image):
16727 * xselect.c (Fx_register_dnd_atom):
16728 Simplify previous changes by using xpalloc.
16730 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16731 since either will do and ptrdiff_t is convenient with xpalloc.
16733 * charset.c (charset_table_size)
16734 (struct charset_sort_data.priority): Now ptrdiff_t.
16735 (charset_compare): Don't overflow if priorities differ greatly.
16736 (Fsort_charsets): Don't assume list length fits in int.
16737 Check for size-calculation overflow when allocating sort data.
16738 (syms_of_charset): Allocate an initial charset table that is
16739 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16741 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16743 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16744 The actual value is always <= INT_MAX, and leaving it unsigned made
16745 overflow checking harder.
16747 * dispextern.h (struct glyph_matrix.rows_allocated)
16748 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16749 with xpalloc. The values are still always <= INT_MAX.
16751 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16753 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16754 (SAFE_NALLOCA): New macro.
16756 * region-cache.c (struct boundary.pos, find_cache_boundary)
16757 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16758 (set_cache_region, invalidate_region_cache)
16759 (revalidate_region_cache, know_region_cache, region_cache_forward)
16760 (region_cache_backward, pp_cache):
16761 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16762 so that ptrdiff_t * can be passed to xpalloc.
16763 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16764 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16765 (pp_cache): Don't assume cache_len fits in int.
16766 * region-cache.h: Adjust extern decls to match.
16768 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16769 EMACS_INT, since either will do, for xpalloc.
16771 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16772 (xnmalloc, xnrealloc, xpalloc): New functions.
16774 * bidi.c (bidi_shelve_header_size): New constant.
16775 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16776 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16778 * bidi.c (bidi_cache_shrink):
16779 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16781 Don't update size of array until after memory allocation succeeds,
16782 because xmalloc/xrealloc may not return.
16783 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16784 now that we have proper integer overflow checking.
16785 (record_overlay_string, overlay_strings): Catch overflows when
16786 calculating size of overlay_str_buf.
16788 * callproc.c (Fcall_process): Check for size overflow when
16789 calculating size of args2.
16790 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16791 Normally we prefer signed values, but sticking with ptrdiff_t would
16792 require adding more-complicated checks.
16794 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16795 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16796 Redo buffer-overflow calculations to avoid integer overflow.
16797 Add a FIXME comment where memory seems to be over-allocated.
16799 * character.c (Fstring): Check for size-calculation overflow.
16801 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16802 unnecessary integer overflow. Check for size overflow.
16803 (encode_coding_object): Don't update size until xmalloc succeeds.
16805 * composite.c (get_composition_id): Check for overflow in glyph
16806 length calculations.
16808 Integer and memory overflow fixes for display code.
16809 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16810 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16811 (scrolling_window): Check for overflow in size calculations.
16812 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16813 Don't assume glyph table len fits in int.
16814 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
16815 (row_table_size): Now ptrdiff_t, not int.
16816 (scrolling_window): Avoid overflow in size calculations.
16817 Don't update size until allocation succeeds.
16818 * fns.c (concat): Check for overflow in size calculations.
16819 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16820 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16821 (NEXT_ALMOST_PRIME_LIMIT): New constant.
16823 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16824 (get_doc_string): Check for size calculation overflow.
16825 Don't update size until allocation succeeds.
16826 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16827 EMACS_INT, where ptrdiff_t will do.
16828 (Fsubstitute_command_keys): Check for string overflow.
16830 * editfns.c (set_time_zone_rule): Don't assume environment length
16832 (message_length): Now ptrdiff_t, not int.
16833 (Fmessage_box): Don't update size until allocation succeeds.
16834 Don't assume message length fits in int.
16835 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16837 * emacs.c (main): Do not reallocate argv, since there is a null at
16838 the end that can be overwritten, and this way there's no need to
16839 worry about size-calculation overflow.
16840 (sort_args): Check for size-calculation overflow.
16842 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16844 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16846 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16847 (x_set_scroll_bar_width, x_figure_window_size):
16848 Check for integer overflow.
16849 (x_set_alpha): Do not assume XINT fits in int.
16851 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16852 This is for the members text_lines, text_cols, total_lines, total_cols,
16853 where the system imposes an 'int' limit.
16855 * fringe.c (Fdefine_fringe_bitmap):
16856 Don't update size until alloc works.
16858 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16859 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16861 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16862 Check for size-calculation overflow.
16863 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16864 do, as we prefer signed integers.
16865 (id_to_widget.max_size, id_to_widget.used)
16866 (xg_store_widget_in_map, xg_remove_widget_from_map)
16867 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16868 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16869 Use and return ptrdiff_t, not int.
16870 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16871 * gtkutil.h: Change prototypes to match the above.
16873 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16874 are duplicate now that they've been promoted to lisp.h.
16875 (x_allocate_bitmap_record, x_alloc_image_color)
16876 (make_image_cache, cache_image, xpm_load):
16877 Don't update size until alloc is done.
16878 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
16880 Check for size calculation overflow.
16881 (ct_colors_allocated_max): New constant.
16882 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
16885 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
16886 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
16887 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16888 Use ptrdiff_t, not int, to count maps.

16920 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16921 for command line length. Do not attempt to address one before the
16922 beginning of an array, as that's not portable.
16924 * term.c (max_frame_lines): Remove; unused.

16954 memory exhaustion (the usual treatment), rather than aborting.
16956 * xfns.c (x_encode_text, x_set_name_internal)
16957 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16958 sizes, since they can exceed INT_MAX in size. Check for size
16959 calculation overflow.
16961 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16962 (xg_select): Check for size calculation overflow.
16963 Don't update size until alloc done.
16965 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16966 as sprintf is limited to int lengths.
16968 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16969 (X_LONG_MIN): New macros.
16970 Use them to make the following changes clearer.
16971 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16972 This change doesn't affect the value now, but it may help remind
16973 future maintainers not to raise the value too much later.
16974 (SELECTION_QUANTUM): Remove, replacing with ...
16975 (selection_quantum): ... new function, which avoids overflow.
16977 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16978 assumption that selection length fits in 'int'.
16979 (x_reply_selection_request, x_handle_selection_request)
16980 (x_get_window_property, receive_incremental_selection)

16995 Don't store size until memory allocation succeeds.
16996 (x_get_window_property): Plug memory leak on memory exhaustion.
16997 Don't double-block input; malloc is safe here. Don't assume 2**34
16998 - 4 fits in unsigned long. Add an xassert to check
16999 XGetWindowProperty overflow. Be more careful about overflow
17000 calculations, and distinguish size from memory overflow better.
17001 (receive_incremental_selection): When tracing, don't assume
17002 unsigned int is less than INT_MAX.
17003 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

17006 in the range -65535 through -1 fit in an X unsigned short.
17007 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17008 result parameters unless successful. Rely on cons_to_unsigned
17009 to report problems with elements; the old code wasn't right anyway.
17010 (x_check_property_data): Check for int overflow; we cannot use
17011 a wider type due to X limits.
17012 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

17044 * lisp.h (hash_lookup, hash_put):
17045 * minibuf.c (Ftest_completion):
17046 Use ptrdiff_t for hash table indexes, not int (which is too
17047 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17048 32-bit --with-wide-int hosts).
17050 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17051 Add a FIXME comment about memory leaks.

17059 with outlandish widths.
17060 * character.h (sanitize_tab_width): Rename from sanitize_width,
17061 now that we have two such functions. All uses changed.

17079 * xterm.c: Don't go over XClientMessageEvent limit.
17080 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17081 (x_send_scroll_bar_event): Likewise. Check that the size does not
17082 exceed limits imposed by XClientMessageEvent, as well as the usual
17083 ptrdiff_t and size_t limits.
17085 * keyboard.c: Overflow, signedness and related fixes.
17086 (make_lispy_movement): Use same integer type in forward decl
17087 that is used in the definition.
17088 (read_key_sequence, keyremap_step):
17089 Change bufsize argument back to int, undoing my 2011-03-30 change.
17090 We prefer signed types, and int is wide enough here.
17091 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17092 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17093 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17094 length, not size_t. Use ptrdiff_t for index, not int.
17095 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17096 possibility of integer overflow.
17098 Overflow, signedness and related fixes for images.

17124 Prefer int to unsigned where either will do.
17125 (tiff_handler): New function, combining the cores of the
17126 old tiff_error_handler and tiff_warning_handler.
17127 This function is rewritten to use vsnprintf and thereby avoid
17128 stack buffer overflows. It uses only the features of vsnprintf
17129 that are common to both POSIX and native Microsoft.
17130 (tiff_error_handler, tiff_warning_handler): Use it.
17131 (tiff_load, gif_load, imagemagick_load_image):
17132 Don't assume :index value fits in 'int'.
17133 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17134 (imagemagick_load_image): Check that crop parameters fit into
17135 the integer types that MagickCropImage accepts. Don't assume
17136 Vimagemagick_render_type has a nonnegative value. Don't assume
17137 size_t fits in 'long'.
17138 (gs_load): Use printmax_t to print the widest integers possible.

17151 handle_single_display_spec, not just 1 or zero.
17152 (handle_single_display_spec): If the display spec is of the form
17153 `(space ...)', and specifies display in the text area, return 2
17155 (try_cursor_movement): Check for the need to scroll more
17156 accurately, and prefer exact match for point under bidi.
17157 Don't advance `row' beyond the last row of the window.

17175 buffers, return left-to-right.
17176 (set_cursor_from_row): Consider candidate row a win if its glyph
17177 represents a newline and point is on that newline. Fixes cursor
17178 positioning on the newline at EOL of R2L text within L2R
17179 paragraph, and vice versa.
17180 (try_cursor_movement): Check continued rows, in addition to
17181 continuation rows. Fixes unwarranted scroll when point enters a
17182 continued line of R2L text within an L2R paragraph, or vice versa.
17183 (cursor_row_p): Consider the case of point being equal to
17184 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

17213 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17214 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17215 candidate is selected by the mouse, and that candidate has a
17216 composed character under the mouse.
17218 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17219 coordinates reported by pos-visible-in-window-p for a composed
17220 character in column zero.

17228 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17229 consider it a hit if to_charpos is anywhere in the range of the
17230 composed buffer positions.
17232 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17234 * image.c (gif_load): Don't assume that each subimage has the same
17235 dimensions as the base image. Handle disposal method that is
17236 "undefined" by the gif spec (Bug#9335).
17238 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17240 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17250 a composition, take its buffer position from IT->cmp_it.charpos.
17251 Fixes cursor positioning at the beginning of a line that begins
17252 with a composed character.
17254 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17256 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17257 character bidirectional type, use STRONG_L instead. Fixes crashes
17258 in a buffer produced by `describe-categories'.
17260 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17261 members before the level stack, so they would be saved and
17262 restored when copying iterator state. Fixes incorrect reordering
17263 around TABs covered by display properties.

17337 * xdisp.c (move_it_in_display_line_to): Don't invoke
17338 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17339 ppos_it. Fixes vertical cursor motion when line beginning is
17340 covered by an image. (Bug#9296)
17342 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17344 * nsterm.h (ns_run_ascript): Declare.
17345 (NSAPP_DATA2_RUNASSCRIPT): Define.
17347 * nsfns.m (as_script, as_result, as_status): New static variables.
17348 (ns_run_ascript): New function.
17349 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17350 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17351 the event loop. Get status from as_status (Bug#7276).
17353 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17354 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17355 the event loop (Bug#7276).
17357 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17359 * gnutls.c (QCgnutls_bootprop_priority)
17360 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
17361 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
17362 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
17363 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
17364 (QCgnutls_bootprop_verify_hostname_error)
17365 (QCgnutls_bootprop_callbacks_verify): Rename from
17366 Qgnutls_bootprop_..., all uses changed.
17368 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
17371 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
17373 * xfaces.c (Qframe_set_background_mode): Now static.
17374 * dispextern.h (Qframe_set_background_mode): Remove decl.
17376 * process.c (Fnetwork_interface_info): Declare local only if needed.
17378 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
17380 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
17381 (Fnetwork_interface_list): Allocate in increments of bytes instead
17382 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17383 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17385 (struct ifflag_def): notrailers is smart on OSX.
17386 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17387 Get hardware address with getifaddrs if available.
17389 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17391 * xdisp.c (iterate_out_of_display_property): xassert that
17392 IT->position is set to within IT->object's boundaries. Break from
17393 the loop as soon as EOB is reached; avoids infloops in redisplay
17394 when IT->position is set up wrongly due to some bug.
17395 Set IT->current to match the bidi iterator unconditionally.
17396 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17397 entry. Force push_it to save on the stack the current
17398 buffer/string position, to be restored by pop_it. Fix flags in
17399 the iterator structure wrt the object coming from a display
17400 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17401 properties. (Bug#9284)
17403 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17405 * fontset.c (fontset_get_font_group): Add proper type checks.
17408 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17410 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
17411 and LC_VERSION_MIN_MACOSX.
17412 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
17413 (dump_it) [LC_FUNCTION_STARTS]: Use it.
17415 2011-08-08 Eli Zaretskii <eliz@gnu.org>
17417 * xdisp.c (forward_to_next_line_start): Allow to use the
17418 no-display-properties-and-no-overlays under bidi display.
17419 Set disp_pos in the bidi iterator to avoid searches for display
17420 properties and overlays.
17422 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17424 * editfns.c (Fset_time_zone_rule): Document relationship with the
17427 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
17428 the font entity extracted from the cache (Bug#8109).
17430 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17432 * composite.c (autocmp_chars): Don't reset point. That is done by
17433 restore_point_unwind (Bug#5984).
17435 2011-08-07 Juri Linkov <juri@jurta.org>
17437 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17438 to show the arg `TIME' instead of `TIMEVAL'.
17440 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17442 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17443 display property strides EOL and includes a newline, as in
17444 longlines-mode. (Bug#9254)
17445 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17446 word-wrap under bidirectional display. (Bug#9224)
17448 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17449 is non-zero, even if the data buffer is NULL. Fixes a crash in
17450 vertical-motion with longlines-mode. (Bug#9254)
17452 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17454 * bidi.c <bidi_cache_total_alloc>: Now static.
17455 (bidi_initialize): Initialize bidi_cache_total_alloc.
17457 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17460 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17461 amount allocated this far in `bidi_cache_total_alloc'.
17462 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17463 non-zero, only free the data buffer without restoring the cache
17464 contents. All callers changed.
17466 * dispextern.h (bidi_unshelve_cache): Update prototype.
17468 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17469 (move_it_in_display_line, move_it_to)
17470 (move_it_vertically_backward, move_it_by_lines): Replace the call
17471 to xfree to an equivalent call to bidi_unshelve_cache.
17472 (move_it_in_display_line_to): Fix logic of returning
17473 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17475 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17477 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17478 came from a string character with a `cursor' property. (Bug#9229)
17480 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17482 * Makefile.in (LIB_PTHREAD): New variable.
17483 (LIBES): Add LIB_PTHREAD (Bug#9216).
17485 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17486 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17488 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17490 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17492 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17494 * xterm.c (x_find_topmost_parent): New function.
17495 (x_set_frame_alpha): Find topmost parent window with
17496 x_find_topmost_parent and set the property there also (bug#9181).
17497 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17499 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17501 * callproc.c (Fcall_process): Avoid vfork clobbering
17502 the local vars buffer, coding_systems, current_dir.
17504 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17506 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17508 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17510 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17511 so that it is not optimized away.
17513 * xdisp.c (compute_display_string_pos): Remove unused local.
17515 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17517 Fix slow cursor motion and scrolling in large buffers with
17518 selective display, like Org Mode buffers. (Bug#9218)
17520 * dispextern.h (struct bidi_it): New member disp_prop_p.
17522 * xdisp.c: Remove one-slot cache of display string positions.
17523 (compute_display_string_pos): Accept an additional argument
17524 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17525 for a display string or property. If found, set DISP_PROP_P
17528 * bidi.c (bidi_fetch_char): Accept an additional argument
17529 DISP_PROP_P, and pass it to compute_display_string_pos.
17530 Only handle text covered by a display string if DISP_PROP_P is returned
17531 non-zero. All callers of bidi_fetch_char changed.
17533 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17535 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17537 2010-12-03 Don March <don@ohspite.net>
17539 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17540 last character M-[char] is translated to ESC [char] (bug#7541).
17542 2011-08-02 Kenichi Handa <handa@m17n.org>
17544 * lisp.h (uniprop_table): Extern it.
17546 * chartab.c (uniprop_table): Make it non-static.
17548 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17550 * xdisp.c (forward_to_next_line_start): Accept additional argument
17551 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17553 (reseat_at_next_visible_line_start): Use the bidi iterator state
17554 returned by forward_to_next_line_start to restore the state of
17555 it->bidi_it after backing up to previous newline. (Bug#9212)
17557 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17559 * regex.c (re_comp): Protoize.
17560 (re_exec): Fix return type.
17561 (regexec): Fix type of `ret'. (Bug#9203)
17563 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17565 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17566 This is needed if max-image-size is a floating-point number.
17568 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17570 * print.c (print_object): Print empty symbol as ##.
17572 * lread.c (read1): Read ## as empty symbol.
17574 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17576 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17577 setting frame foreground color (Bug#9175).
17578 (x_set_background_color): Likewise.
17580 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17581 contents (Bug#9176).
17582 (EmacsTooltip -init): Remove bezels and add shadows to
17585 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17586 or scroll bar (Bug#8470).
17588 * nsfont.m (nsfont_open): Remove assignment to voffset and
17589 unnecessary vars hshink, expand, hd, full_height, min_height.
17590 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17592 * nsterm.h (nsfont_info): Remove voffset field.
17594 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17596 Implement strike-through and overline on NextStep (Bug#8863).
17598 * nsfont.m (nsfont_open): Use underline position provided by font,
17599 instead of hard-coded value of 2.
17600 (nsfont_draw): Call ns_draw_text_decoration instead.
17602 * nsterm.h: Add declaration for ns_draw_text_decoration.
17604 * nsterm.m (ns_draw_text_decoration): New function for drawing
17605 underline, overline, and strike-through.
17606 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17607 ns_draw_text_decoration. Change treatment of cursor drawing to
17608 accommodate underlining, etc.
17610 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17612 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17615 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17617 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17618 Without this fix, if a signal arrives just after memory fills up,
17619 'malloc' might be invoked reentrantly.
17621 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17622 In other words, assume that every image size is allowed, on non-X
17623 hosts. This assumption is probably wrong, but it lets Emacs compile.
17625 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17627 * regex.c (re_iswctype): Convert return values to boolean.
17629 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17631 * xdisp.c (compute_display_string_pos): Don't use cached display
17632 string position if the buffer had its restriction changed.
17635 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17637 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17639 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17641 Integer signedness and overflow and related fixes. (Bug#9079)
17643 * bidi.c: Integer size and overflow fixes.
17644 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17645 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17646 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17647 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17648 (bidi_find_other_level_edge):
17649 Use ptrdiff_t instead of EMACS_INT where either will do.
17650 This works better on 32-bit hosts configured --with-wide-int.
17651 (bidi_cache_ensure_space): Check for size-calculation overflow.
17652 Use % rather than repeated addition, for better worst-case speed.
17653 Don't set bidi_cache_size until after xrealloc returns, because it
17655 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17656 (bidi_cache_ensure_space): Also check that the bidi cache size
17657 does not exceed that of the largest Lisp string or buffer. See Eli
17658 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17660 * alloc.c (__malloc_size_t): Remove.
17661 All uses replaced by size_t. See Andreas Schwab's note
17662 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17664 * image.c: Improve checking for integer overflow.
17665 (check_image_size): Assume that f is nonnull, since
17666 it is always nonnull in practice. This is one less thing to
17667 worry about when checking for integer overflow later.
17668 (x_check_image_size): New function, which checks for integer
17669 overflow issues inside X.
17670 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17671 This removes the need for a memory_full check.
17672 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17673 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17674 (xbm_read_bitmap_data): Change locals back to 'int', since
17675 their values must fit in 'int'.
17676 (xpm_load_image, png_load, tiff_load):
17677 Invoke x_create_x_image_and_pixmap earlier,
17678 to avoid much needless work if the image is too large.
17679 (tiff_load): Treat overly large images as if
17680 x_create_x_image_and_pixmap failed, not as malloc failures.
17681 (gs_load): Use x_check_image_size.
17683 * gtkutil.c: Omit integer casts.
17684 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17685 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17687 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17689 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17690 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17691 would wrongly return t on a 64-bit host.
17693 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17694 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17695 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17696 and therefore cause GCC to emit a bogus diagnostic in some cases.
17698 * image.c: Integer signedness and overflow and related fixes.
17699 This is not an exhaustive set of fixes, but it's time to
17700 record what I've got.
17701 (lookup_pixel_color, check_image_size): Remove redundant decls.
17702 (check_image_size): Don't assume that arbitrary EMACS_INT values
17703 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17704 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17705 (tiff_load, imagemagick_load_image):
17706 Check for overflow in size calculations.
17707 (x_create_x_image_and_pixmap): Remove unnecessary test for
17708 xmalloc returning NULL; that can't happen.
17709 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17710 (xpm_color_bucket): Use better integer hashing function.
17711 (xpm_cache_color): Don't possibly over-allocate memory.
17712 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17713 (gif_memory_source):
17714 Use ptrdiff_t, not int or size_t, to record sizes.
17715 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17716 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17717 either works, as we prefer signed integers.
17718 (tiff_read_from_memory, tiff_write_from_memory):
17719 Return tsize_t, not size_t, since that's what the TIFF API wants.
17720 (tiff_read_from_memory): Don't fail simply because the read would
17721 go past EOF; instead, return a short read.
17722 (tiff_load): Omit no-longer-needed casts.
17723 (Fimagemagick_types): Don't assume size fits into 'int'.
17725 Improve hashing quality when configured --with-wide-int.
17726 * fns.c (hash_string): New function, taken from sxhash_string.
17727 Do not discard information about ASCII character case; this
17728 discarding is no longer needed.
17729 (sxhash-string): Use it. Change sig to match it. Caller changed.
17730 * lisp.h: Declare it.
17731 * lread.c (hash_string): Remove, since we now use fns.c's version.
17732 The fns.c version returns a wider integer if --with-wide-int is
17733 specified, so this should help the quality of the hashing a bit.
17735 * emacs.c: Integer overflow minor fix.
17736 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17737 Define only if GNU_LINUX.
17738 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17740 * dispnew.c: Integer signedness and overflow fixes.
17741 Remove unnecessary forward decls, that were a maintenance hassle.
17742 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17744 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17745 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17746 (prepare_desired_row, line_draw_cost):
17747 Use int, not unsigned, where either works.
17748 (save_current_matrix, restore_current_matrix):
17749 Use ptrdiff_t, not size_t, where either works.
17750 (init_display): Check for overflow more accurately, and without
17751 relying on undefined behavior.
17753 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17754 Remove, replacing with the new symbols in lisp.h. All uses changed.
17755 * fileio.c (make_temp_name):
17756 * filelock.c (lock_file_1, lock_file):
17757 * xdisp.c (message_dolog):
17758 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17759 Use pMd etc. instead.
17760 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17761 replacing the pWIDE etc. symbols removed from editfns.c.
17763 * keyboard.h (num_input_events): Now uintmax_t.
17764 This is (very slightly) less likely to mess up due to wraparound.
17767 * buffer.c: Integer signedness fixes.
17768 (alloc_buffer_text, enlarge_buffer_text):
17769 Use ptrdiff_t rather than size_t when either will do, as we prefer
17772 * alloc.c: Integer signedness and overflow fixes.
17773 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17774 (__malloc_size_t): Default to size_t, not to int.
17775 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17776 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17777 Prefer ptrdiff_t to size_t when either would do, as we prefer
17779 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17780 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17781 Now const. Initialize with values that are in range even if char
17783 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17784 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17785 These functions do the right thing with sizes > 2**32.
17786 (check_depth): Now ptrdiff_t, not int.
17787 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17788 Adjust to new way of storing sizes. Check for size overflow bugs
17790 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17791 slightly wrong anyway, as it missed one instance of
17792 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17793 (refill_memory_reserve): Omit needless cast to size_t.
17794 (mark_object_loop_halt): Mark as externally visible.
17796 * xselect.c: Integer signedness and overflow fixes.
17797 (Fx_register_dnd_atom, x_handle_dnd_message):
17798 Use ptrdiff_t, not size_t, since we prefer signed.
17799 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17800 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17801 x_dnd_atoms_size and x_dnd_atoms_length.
17803 * doprnt.c: Prefer signed to unsigned when either works.
17805 * doprnt.c (doprnt):
17807 * xdisp.c (vmessage):
17808 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17809 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17810 prefer signed arithmetic to avoid comparison confusion.
17811 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17812 but is a bit tricky.
17814 Assume freestanding C89 headers, string.h, stdlib.h.
17815 * data.c, doprnt.c, floatfns.c, print.c:
17816 Include float.h unconditionally.
17817 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17818 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17819 * regex.c: Likewise for stddef.h, string.h.
17820 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17821 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17822 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17823 (STDC_HEADERS): Remove obsolete defines.
17824 * sysdep.c: Include limits.h unconditionally.
17826 Assume support for memcmp, memcpy, memmove, memset.
17827 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17828 * regex.c (memcmp, memcpy):
17829 Remove; we assume C89 now.
17831 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17832 (__malloc_safe_bcopy): Remove; no longer needed.
17834 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17835 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17836 well either way, and we prefer signed to unsigned.
17838 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17840 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17841 closes the connection while we're reading (bug#9182).
17843 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17845 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17846 are specified (Bug#9168).
17848 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17850 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17851 Found by GCC static checking and --with-wide-int on a 32-bit host.
17853 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17855 * xdisp.c (compute_display_string_pos): Fix logic of caching
17856 previous display string position. Initialize cached_prev_pos to
17857 -1. Fixes slow-down at the beginning of a buffer.
17859 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17861 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17862 for attrs[LFACE_FONTSET_INDEX].
17864 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17866 * xml.c (parse_region): Remove unused local
17867 that was recently introduced.
17869 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17871 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17872 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17874 * xdisp.c (move_it_in_display_line_to): Record the best matching
17875 position for TO_CHARPOS while scanning the line, and restore it on
17876 exit if none of the characters scanned was an exact match.
17877 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17878 when exact match is impossible due to invisible text, and the
17879 lines are truncated.
17881 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17883 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17886 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17888 Fix a significant slow-down of cursor motion with C-n, C-p,
17889 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17890 auto-repeat under bidi redisplay in fontified buffers.
17891 * xdisp.c (compute_stop_pos_backwards): New function.
17892 (next_element_from_buffer): Call compute_stop_pos_backwards to
17893 find a suitable prev_stop when we find ourselves before
17895 (reseat): Don't look for prev_stop, as that could mean a very long
17897 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17898 <cached_disp_overlay_modiff>: Cache for last found display string
17900 (compute_display_string_pos): Return the cached position if asked
17901 about the same buffer in the same area of character positions, and
17902 the buffer wasn't changed since the time the display string
17903 position was cached.
17905 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17907 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17908 is an integer, which is important for empty lines. (Bug#9149)
17910 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17912 * frame.c (Fmodify_frame_parameters): In tty case, update the
17913 default face if necessary (Bug#4238).
17915 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17917 * editfns.c (Fstring_to_char): No need to explain what a character
17918 is in the docstring (Bug#6576).
17920 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17922 * xml.c (parse_region): Make sure we always return a tree.
17924 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17926 * xml.c (parse_region): If a document contains only comments,
17929 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17931 * xml.c (make_dom): Return comments, too.
17933 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17936 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17937 and the surrounding thread.
17938 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17939 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17940 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17942 * s/openbsd.h (BROKEN_SIGIO): Define.
17943 * unexelf.c (unexec) [__OpenBSD__]:
17944 Don't update the .mdebug section of the Alpha COFF symbol table.
17946 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17948 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17951 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17953 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17954 This fixes some race conditions on the permissions of any newly
17957 * alloc.c (valid_pointer_p): Use pipe, not open.
17958 This fixes some permissions issues when debugging.
17960 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17961 If fchown fails to set both uid and gid, try to set just gid,
17962 as that is sometimes allowed. Adjust the file's mode to eliminate
17963 setuid or setgid bits that are inappropriate if fchown fails.
17965 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17967 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17968 to compare Lisp_Objects.
17969 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17970 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17971 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17973 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17975 * lread.c (read_integer): Unread even EOF character.
17976 (read1): Likewise. Properly record start position of symbol.
17978 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17979 symbol character follows.
17981 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17983 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17984 This works around a problem with the previous change to Fcopy_file.
17985 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17986 and without this change, GCC might complain about discarding
17987 fchown's return value.
17989 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17991 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17993 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17995 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17997 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17999 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
18000 it's used from the C level.
18002 * process.c: Use the same condition for POLL_FOR_INPUT in both
18003 keyboard.c and process.c (bug#1858).
18005 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18007 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18008 (Fgnutls_boot): Use it.
18010 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18012 * doc.c (Fsubstitute_command_keys): Revert last change.
18014 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18016 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18017 quotes the next character, and doesn't affect other longer
18018 sequences (bug#8935).
18020 * lread.c (syms_of_lread): Clarify that is isn't only
18021 `eval-buffer' and `eval-defun' that's affected by
18022 `lexical-binding' (bug#8460).
18024 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18026 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18027 bidi redisplay when a line includes both an image and is truncated.
18029 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18031 Fix minor problems found by static checking.
18032 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18033 (elsz): Now a signed constant, not a size_t var. We prefer signed
18034 types to unsigned, to avoid integer comparison confusion. Without
18035 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18036 "cannot optimize loop, the loop counter may overflow", a symptom
18038 * indent.c (Fvertical_motion): Mark locals as initialized.
18039 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18041 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18043 * search.c (Fre_search_backward): Mention `case-fold-search' in
18044 all the re_search_* functions (bug#8138).
18046 * keyboard.c (Fopen_dribble_file): Document when the file is

18057 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
18058 (reseat_to_string): Initialize bidi_it->string.s and
18059 bidi_it->string.schars.
18060 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
18061 NULL (avoids a crash in bidi_paragraph_init).
18062 Initialize itb.string.lstring.
18063 (init_iterator): Call bidi_init_it only of a valid
18064 buffer position was specified. Initialize paragraph_embedding to
18066 (reseat_to_string): Initialize the bidi iterator.
18067 (display_string): If we need to ignore text properties of
18068 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18069 original value of -1 will not work with bidi.)
18070 (compute_display_string_pos): First arg is now struct
18071 `text_pos *'; all callers changed. Support display properties on
18073 (compute_display_string_end): Support display properties on Lisp
18075 (init_iterator, reseat_1, reseat_to_string): Initialize the
18076 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18077 when iterating on a string not from display properties).
18078 (compute_display_string_pos, compute_display_string_end):
18079 Fix calculation of the object to scan. Fixes an error when using
18081 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18082 base_level_stop; instead, set base_level_stop to BEGV.
18083 Fixes crashes in vertical-motion.
18084 (next_element_from_buffer): Improve commentary for when
18085 the iterator is before prev_stop.
18086 (init_iterator): Initialize bidi_p from the default value of
18087 bidi-display-reordering, not from buffer-local value. Use the
18088 buffer-local value only if initializing for buffer iteration.
18089 (handle_invisible_prop): Support invisible properties on strings
18090 that are being bidi-reordered.
18091 (set_iterator_to_next): Support bidi reordering of C strings and
18093 (next_element_from_string): Support bidi reordering of Lisp
18095 (handle_stop_backwards): Support Lisp strings as well.
18096 (display_string): Support display of R2L glyph rows.
18097 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18098 (init_iterator): Don't initialize it->bidi_p for strings
18100 (reseat_to_string): Initialize it->bidi_p for strings here.
18101 (next_element_from_string, next_element_from_c_string)
18102 (next_element_from_buffer): Add xassert's for correspondence
18103 between IT's object being iterated and it->bidi_it.string
18105 (face_before_or_after_it_pos): Support bidi iteration.
18106 (next_element_from_c_string): Handle the case of the first string
18107 character that is not the first one in the visual order.
18108 (get_visually_first_element): New function, refactored from common
18109 parts of next_element_from_buffer, next_element_from_string, and
18110 next_element_from_c_string.
18111 (tool_bar_lines_needed, redisplay_tool_bar)
18112 (display_menu_bar): Force left-to-right direction. Add a FIXME
18113 comment for making that be controlled by a user option.
18114 (push_it, pop_it): Save and restore the state of the
18115 bidi iterator. Save and restore the bidi_p flag.
18116 (pop_it): Iterate out of display property for string iteration as
18118 (iterate_out_of_display_property): Support iteration over strings.
18119 (handle_single_display_spec): Set up it->bidi_it for iteration
18120 over a display string, and call bidi_init_it.
18121 (handle_single_display_spec, next_overlay_string)
18122 (get_overlay_strings_1, push_display_prop): Set up the bidi
18123 iterator for displaying display or overlay strings.
18124 (forward_to_next_line_start): Don't use the shortcut if
18126 (back_to_previous_visible_line_start): If handle_display_prop
18127 pushed the iterator stack, restore the internal state of the bidi
18128 iterator by calling bidi_pop_it same number of times.
18129 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18130 and we are bidi-iterating, don't decrement the iterator position;
18131 instead, set the first_elt flag in the bidi iterator, to produce
18133 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18134 (push_display_prop): xassert that we are iterating a buffer.
18135 (push_it, pop_it): Save and restore paragraph_embedding member.
18136 (handle_single_display_spec, next_overlay_string)
18137 (get_overlay_strings_1, reseat_1, reseat_to_string)
18138 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18139 correctly. Don't assume unibyte strings are not bidi-reordered.
18140 (compute_display_string_pos)
18141 (compute_display_string_end): Fix handling the case of C string.
18142 (push_it, pop_it): Save and restore from_disp_prop_p.
18143 (handle_single_display_spec, push_display_prop): Set the
18144 from_disp_prop_p flag.

18147 popping after iteration over a string that came from a display
18148 property. Fix a typo in popping stretch info. Add an assertion
18149 for verifying that the iterator position is in sync with the bidi
18151 (handle_single_display_spec, get_overlay_strings_1)
18152 (push_display_prop): Fix initialization of paragraph direction for
18153 string when that of the parent object is not yet determined.
18154 (reseat_1): Call bidi_init_it to resync the bidi
18155 iterator with IT's position. (Bug#7616)
18156 (find_row_edges): If ROW->start.pos gives position
18157 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
18158 (handle_stop, back_to_previous_visible_line_start, reseat_1):
18159 Reset the from_disp_prop_p flag.
18160 (SAVE_IT, RESTORE_IT): New macros.
18161 (pos_visible_p, face_before_or_after_it_pos)
18162 (back_to_previous_visible_line_start)
18163 (move_it_in_display_line_to, move_it_in_display_line)
18164 (move_it_to, move_it_vertically_backward, move_it_by_lines)
18165 (try_scrolling, redisplay_window, display_line): Use them when
18166 saving a temporary copy of the iterator and restoring it back.
18167 (back_to_previous_visible_line_start, reseat_1)
18168 (init_iterator): Empty the bidi cache "stack".
18169 (move_it_in_display_line_to): If iterator ended up at
18170 EOL, but we never saw any buffer positions smaller than
18171 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
18172 motion in bidi-reordered lines.
18173 (move_it_in_display_line_to): Record prev_method and prev_pos
18174 immediately before the call to set_iterator_to_next. Fixes cursor
18175 motion in bidi-reordered lines with stretch glyphs and strings
18176 displayed in margins. (Bug#8133) (Bug#8867)
18177 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
18179 (pos_visible_p): Support positions in bidi-reordered lines.
18180 Save and restore bidi cache.
18182 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
18183 (bidi_paragraph_info): Delete unused struct.
18184 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
18185 (bidi_cache_start): New variable.
18186 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
18188 (bidi_cache_fetch_state, bidi_cache_search)
18189 (bidi_cache_find_level_change, bidi_cache_iterator_state)
18190 (bidi_cache_find, bidi_peek_at_next_level)

18194 (bidi_fetch_char): Accept new argument STRING; all callers
18195 changed. Support iteration over a string. Support strings with
18196 display properties. Support unibyte strings. Fix the type of
18197 `len' according to what STRING_CHAR_AND_LENGTH expects.
18198 (bidi_paragraph_init, bidi_resolve_explicit_1)
18199 (bidi_resolve_explicit, bidi_resolve_weak)
18200 (bidi_level_of_next_char, bidi_move_to_visually_next):
18201 Support iteration over a string.
18202 (bidi_set_sor_type, bidi_resolve_explicit_1)
18203 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
18204 can now be zero (for strings); special values 0 and -1 were
18205 changed to -1 and -2, respectively.
18206 (bidi_char_at_pos): New function.
18207 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
18208 Call it instead of FETCH_MULTIBYTE_CHAR.
18209 (bidi_move_to_visually_next): Abort if charpos or bytepos were not

18293 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
18295 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
18296 The old code sometimes used this field without initializing it.
18298 * alloc.c (gc_sweep): Don't read past end of array.
18299 In theory, the old code could also have corrupted Emacs internals,
18300 though it'd be very unlikely.

18563 (clone_per_buffer_values): Don't assume that
18564 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
18565 This isn't true in general, and it's particularly not true
18566 if Emacs is configured with --with-wide-int.
18567 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18568 New macros, used in the buffer.c change.

18604 Random fixes. E.g., (random) never returned negative values.
18605 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18606 subseconds part to the entropy, as that's a bit more random.
18607 Prefer signed to unsigned, since the signedness doesn't matter and
18608 in general we prefer signed. When given a limit, use a
18609 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18610 latter isn't right if USE_2_TAGS_FOR_INTS.
18611 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18612 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18624 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18625 This is more efficient than Ffile_directory_p and avoids a minor race.
18627 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18629 * buffer.c (Foverlay_put): Say what the return value is
18632 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18633 is a directory before asking whether to use the file name
18635 (barf_or_query_if_file_exists): Make the "File is a directory"
18636 error be more correct.
18638 * fns.c (Frequire): Remove the mention of the .gz files, since
18639 that's installation-specific, but keep the mention of
18640 `get-load-suffixes'.
18642 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
18644 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18650 (syms_of_gnutls): Remove duplicate DEFSYM for
18651 Qgnutls_bootprop_verify_hostname_error, an error for
18652 Qgnutls_bootprop_verify_error (which is no longer used).

18757 * eval.c (struct backtrace): Simplify and port the data structure.
18758 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18759 signed bit field, as this assumption is not portable and it makes
18760 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18761 "char debug_on_exit : 1" as this is not portable either; instead,
18762 use the portable "unsigned int debug_on_exit : 1". Remove unused
18763 member evalargs. Remove obsolete comments about cc bombing out.

18999 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
19000 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
19001 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
19002 since we're not interested in debugging glyphs with old libraries.
19003 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
19004 GCC 4.6.0's static checking.

19046 (x_session_initialize): Do not assume string length fits in int.
19048 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

19094 Don't assume pid_t and time_t fit in unsigned long.
19095 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19096 (current_lock_owner): Prefer signed type for sizes.
19097 Use memcpy, not strncpy, where memcpy is what is really wanted.
19098 Don't assume (via atoi) that time_t and pid_t fit in int.
19099 Check for time_t and/or pid_t out of range, e.g., via a network share.
19100 Don't alloca where an auto var works fine.
19102 * fileio.c: Fix some integer overflow issues.
19103 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19104 Don't assume string length fits in int.
19105 (directory_file_name): Don't assume string length fits in long.
19106 (make_temp_name): Don't assume pid fits in int, or that its print
19107 length is less than 20.
19109 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19111 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19113 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19115 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19116 We prefer signed integers, even for size calculations.
19118 * emacs.c: Don't assume string length fits in 'int'.
19119 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19120 (main): Don't invoke strlen when not needed.
19122 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19123 (XD_DEBUG_MESSAGE): Don't waste a byte.
19125 * callproc.c (getenv_internal_1, getenv_internal)
19126 (Fgetenv_internal):
19127 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19129 * lread.c (invalid_syntax): Omit length argument.
19130 All uses changed. This doesn't fix a bug, but it simplifies the
19131 code away from its former Hollerith-constant appearance, and it's
19132 one less 'int' to worry about when looking at integer-overflow issues.
19133 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19135 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19136 This didn't break anything, but it didn't help either.
19137 It's confusing to put a bogus integer in a place where the actual
19138 value does not matter.
19139 (LIST_END_P): Remove unused macro and its bogus comment.
19140 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19142 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19143 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19145 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19146 We prefer signed types, and the value cannot exceed the EMACS_INT
19147 range anyway (because otherwise the length would not be representable).
19148 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19149 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19150 This avoids a GCC warning when WIDE_EMACS_INT.
19152 * indent.c (sane_tab_width): New function.
19153 (current_column, scan_for_column, Findent_to, position_indentation)
19154 (compute_motion): Use it. This is just for clarity.
19155 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19157 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19159 * lisp.h (lint_assume): New macro.
19160 * composite.c (composition_gstring_put_cache):
19161 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19163 * editfns.c, insdel.c:
19164 Omit unnecessary forward decls, to simplify future changes.
19166 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19168 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19170 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19171 Use much-faster test for byte-length change.
19172 Don't assume string byte-length fits in 'int'.
19173 Check that character arg fits in 'int'.
19174 (mapcar1): Declare byte as byte, for clarity.
19176 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19178 * fns.c (concat): Catch string overflow earlier.
19179 Do not rely on integer wraparound.
19181 * dispextern.h (struct it.overlay_strings_charpos)
19182 (struct it.selective): Now EMACS_INT, not int.
19183 * xdisp.c (forward_to_next_line_start)
19184 (back_to_previous_visible_line_start)
19185 (reseat_at_next_visible_line_start, next_element_from_buffer):
19186 Don't arbitrarily truncate the value of 'selective' to int.
19188 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19190 * composite.c: Don't truncate sizes to 'int'.
19191 (composition_gstring_p, composition_reseat_it)
19192 (composition_adjust_point): Use EMACS_INT, not int.
19193 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19194 not EMACS_UINT, for indexes.
19196 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19198 * buffer.c: Include <verify.h>.
19199 (struct sortvec.priority, struct sortstr.priority):
19200 Now EMACS_INT, not int.
19201 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19202 (struct sortstr.size, record_overlay_string)
19203 (struct sortstrlist.size, struct sortlist.used):
19204 Don't truncate size to int.
19205 (record_overlay_string): Check for size-calculation overflow.
19206 (init_buffer_once): Check at compile-time, not run-time.
19208 2011-06-22 Jim Meyering <meyering@redhat.com>
19210 Don't leak an XBM-image-sized buffer
19211 * image.c (xbm_load): Free the image buffer after using it.
19213 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19216 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19217 that Sun C diagnosed.
19218 * fns.c (secure_hash): Fix pointer signedness issue.
19219 * intervals.c (static_offset_intervals): New function.
19220 (offset_intervals): Use it.
19222 2011-06-21 Leo Liu <sdl.web@gmail.com>
19225 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19228 * fns.c (secure_hash): Rename from crypto_hash_function and change
19229 the first arg to accept symbols.
19230 (Fsecure_hash): New primitive.
19231 (syms_of_fns): New symbols.
19233 2011-06-20 Deniz Dogan <deniz@dogan.se>
19235 * process.c (Fset_process_buffer): Clarify return value in
19238 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19240 * dispnew.c (add_window_display_history): Use BVAR.
19242 * xdisp.c (debug_method_add): Use BVAR.
19243 (check_window_end, dump_glyph_matrix, dump_glyph)
19244 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19246 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19249 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19250 check till after the cache is created in init_frame_faces.
19252 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19254 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19256 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19258 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19259 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19260 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19262 Improve buffer-overflow checking (Bug#8873).
19263 * fileio.c (Finsert_file_contents):
19264 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19265 Remove the old (too-loose) buffer overflow checks.
19266 They weren't needed, since make_gap checks for buffer overflow.
19267 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19268 The old code merely checked for Emacs fixnum overflow, and relied
19269 on undefined (wraparound) behavior. The new code avoids undefined
19270 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19272 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19273 Tune. Don't use wider integers than needed. Don't use alloca.
19274 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19276 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19278 * insdel.c, lisp.h (buffer_overflow): New function.
19279 (insert_from_buffer_1, replace_range, replace_range_2):
19280 * insdel.c (make_gap_larger):
19281 * editfns.c (Finsert_char):
19282 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19284 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19286 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19288 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19290 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19291 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19293 * fileio.c: Don't assume EMACS_INT fits in off_t.
19294 (emacs_lseek): New static function.
19295 (Finsert_file_contents, Fwrite_region): Use it.
19296 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19298 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19300 * fns.c: Don't overflow int when computing a list length.
19301 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19302 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19303 truncation on 64-bit hosts. Check for QUIT every
19304 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19305 faster and is responsive enough.
19306 (Flength): Report an error instead of overflowing an integer.
19307 (Fsafe_length): Return a float if the value is not representable
19308 as a fixnum. This shouldn't happen except in contrived situations.
19309 (Fnthcdr, Fsort): Don't assume list length fits in int.
19310 (Fcopy_sequence): Don't assume vector length fits in int.
19312 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19313 (header_size, word_size): New constants.
19314 (allocate_vectorlike): Don't check size overflow here.
19315 (allocate_vector): Check it here instead, since this is the only
19316 caller of allocate_vectorlike that could cause overflow.
19317 Check that the new vector's length is representable as a fixnum.
19319 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19320 The previous code was bogus. For example, next_almost_prime (32)
19321 returned 39, which is undesirable as it is a multiple of 3; and
19322 next_almost_prime (24) returned 25, which is a multiple of 5 so
19323 why was the code bothering to check for multiples of 7?
19325 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19327 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19329 Variadic C functions now count arguments with ptrdiff_t.
19330 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19331 Back then I didn't know that the Emacs coding style prefers signed int.
19332 Also, in the meantime I found a few more instances where arguments
19333 were being counted with int, which may truncate counts on 64-bit
19334 machines, or EMACS_INT, which may be unnecessarily wide.
19335 * lisp.h (struct Lisp_Subr.function.aMANY)
19336 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19337 Arg counts are now ptrdiff_t, not size_t.
19338 All variadic functions and their callers changed accordingly.
19339 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19340 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19341 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19342 * callint.c (Fcall_interactively): Check arg count for overflow,
19343 to avoid potential buffer overrun. Use signed char, not 'int',
19344 for 'varies' array, so that we needn't bother to check its size
19345 calculation for overflow.
19346 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19347 * eval.c (apply_lambda):
19348 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19349 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19350 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19352 * callint.c (Fcall_interactively): Don't use index var as event count.
19354 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19355 * mem-limits.h (SIZE): Remove; no longer used.
19357 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19359 Remove unnecessary casts.
19360 * xterm.c (x_term_init):
19361 * xfns.c (x_set_border_pixel):
19362 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19363 These aren't needed now that we assume ANSI C.
19365 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19366 It's more likely to cause problems (due to unsigned overflow)
19369 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19371 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19373 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19375 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19377 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19379 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19381 GLYPH_CODE_FACE returns EMACS_INT, not int.
19382 * dispextern.h (merge_faces):
19383 * xfaces.c (merge_faces):
19384 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19385 Don't assume EMACS_INT fits in int.
19387 * character.h (CHAR_VALID_P): Remove unused parameter.
19388 * fontset.c, lisp.h, xdisp.c: All uses changed.
19390 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19392 * fns.c (concat): Minor tuning based on overflow analysis.
19393 This doesn't fix any bugs. Use int to hold character, instead
19394 of constantly refetching from Emacs object. Use XFASTINT, not
19395 XINT, for value known to be a character. Don't bother comparing
19396 a single byte to 0400, as it's always less.
19398 * floatfns.c (Fexpt):
19399 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19401 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19404 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19406 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19407 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19408 incorrectly succeed when S was a string, because 4294967386 was
19409 truncated before it was used.
19411 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19412 Otherwise, an out-of-range integer could cause undefined behavior
19415 * composite.c: Use int, not EMACS_INT, for characters.
19416 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19417 EMACS_INT, for values that are known to be in character range.
19418 This doesn't fix any bugs but is the usual style inside Emacs and
19419 may generate better code on 32-bit machines.
19421 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19422 This is for reasons similar to the recent CHAR_STRING fix.
19423 * charset.c (Fencode_char): Check that character arg is actually
19424 a character. Pass an int to ENCODE_CHAR.
19425 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19426 wider than 'int', as a compile-time check to prevent future regressions
19429 * character.c (char_string): Remove unnecessary casts.
19431 Make sure a 64-bit char is never passed to CHAR_STRING.
19432 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19433 by silently ignoring the top 32 bits, allowing some values
19434 that were far too large to be valid characters.
19435 * character.h: Include <verify.h>.
19436 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19437 arguments are no wider than unsigned, as a compile-time check
19438 to prevent future regressions in this area.
19440 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19441 (Fsubst_char_in_region):
19443 * xdisp.c (decode_mode_spec_coding):
19444 Adjust to CHAR_STRING's new requirement.
19445 * editfns.c (Finsert_char, Fsubst_char_in_region):
19446 * fns.c (concat): Check that character args are actually
19447 characters. Without this test, these functions did the wrong
19448 thing with wildly out-of-range values on 64-bit hosts.
19450 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19451 These casts should not be needed on 32-bit hosts, either.
19452 * keyboard.c (read_char):
19453 * lread.c (Fload): Remove casts to unsigned.
19455 * lisp.h (UNSIGNED_CMP): New macro.
19456 This fixes comparison bugs on 64-bit hosts.
19457 (ASCII_CHAR_P): Use it.
19458 * casefiddle.c (casify_object):
19459 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19460 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19461 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19462 * dispextern.h (FACE_FROM_ID):
19463 * keyboard.c (read_char): Use UNSIGNED_CMP.
19465 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19466 not to EMACS_INT, to avoid GCC warning.
19468 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19470 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19471 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19472 isn't needed on 32-bit machines.
19474 * buffer.c (Fgenerate_new_buffer_name):
19475 Use EMACS_INT for count, not int.
19476 (advance_to_char_boundary): Return EMACS_INT, not int.
19478 * data.c (Qcompiled_function): Now static.
19480 * window.c (window_body_lines): Now static.
19482 * image.c (gif_load): Rename local to avoid shadowing.
19484 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19485 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19486 * alloc.c (make_save_value): Integer argument is now of type
19487 ptrdiff_t, not int.
19488 (mark_object): Use ptrdiff_t, not int.
19489 * lisp.h (pD): New macro.
19490 * print.c (print_object): Use it.
19492 * alloc.c: Use EMACS_INT, not int, to count objects.
19493 (total_conses, total_markers, total_symbols, total_vector_size)
19494 (total_free_conses, total_free_markers, total_free_symbols)
19495 (total_free_floats, total_floats, total_free_intervals)
19496 (total_intervals, total_strings, total_free_strings):
19497 Now EMACS_INT, not int. All uses changed.
19498 (Fgarbage_collect): Compute overall total using a double, so that
19499 integer overflow is less likely to be a problem. Check for overflow
19500 when converting back to an integer.
19501 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19502 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19503 These were 'int' variables that could overflow on 64-bit hosts;
19504 they were never used, so remove them instead of repairing them.
19505 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19506 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19507 Previously, this ceilinged at INT_MAX, but that doesn't work on
19509 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19511 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19512 (allocate_vectorlike): Check for ptrdiff_t overflow.
19513 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19514 when a (possibly-narrower) signed value would do just as well.
19515 We prefer using signed arithmetic, to avoid comparison confusion.
19517 * alloc.c: Catch some string size overflows that we were missing.
19518 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19519 for convenience in STRING_BYTES_MAX.
19520 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19521 The definition here is exact; the one in lisp.h was approximate.
19522 (allocate_string_data): Check for string overflow. This catches
19523 some instances we weren't catching before. Also, it catches
19524 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19525 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19526 and ptrdiff_t and EMACS_INT are both 64 bits.
19528 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19529 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19530 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19532 * character.c (string_escape_byte8): Fix nbytes/nchars typo.

19978 * keymap.c (access_keymap, silly_event_symbol_error):
19979 XUINT -> XFASTINT, since the integer must be nonnegative.
19980 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
19981 since it makes no difference and we prefer signed.
19982 * keyboard.c (record_char): Use XUINT when all the neighbors do.
19983 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

20030 code. Minor doc-string fixes.
20032 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
20034 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
20035 Do not assume that spare memory exists; that assumption is valid
20036 only if SYSTEM_MALLOC.
20037 (LARGE_REQUEST): New macro, so that the issue of large requests
20038 is separated from the issue of spare memory.
20040 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
20042 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

20068 New error handlers.
20069 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
20070 Obey Vx_select_enable_clipboard_manager. Catch errors in

20077 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
20079 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20081 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap

20094 (bidi_cache_search, bidi_cache_iterator_state)
20095 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
20096 (bidi_level_of_next_char, bidi_move_to_visually_next):
20097 Support character positions inside a run of characters covered by a
20099 (bidi_paragraph_init, bidi_resolve_explicit_1)
20100 (bidi_level_of_next_char): Call bidi_fetch_char and
20101 bidi_fetch_char_advance instead of FETCH_CHAR and

20104 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
20106 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
20107 instead of using explicit *_CHAR codes.
20108 (bidi_resolve_explicit, bidi_resolve_weak):
20109 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
20110 bidirectional text is supported only in multibyte buffers.
20111 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
20112 it to initialize the frame_window_p member of struct bidi_it.

20116 bidi_it->nchars is non-positive.
20117 (bidi_level_of_next_char): Don't try to lookup the cache for the
20118 next/previous character if nothing is cached there yet, or if we
20119 were just reseat()'ed to a new position.
20121 * xdisp.c (set_cursor_from_row): Set start and stop points
20122 according to the row's direction when priming the loop that looks
20123 for the glyph on which to display cursor.
20124 (single_display_spec_intangible_p): Function deleted.
20125 (display_prop_intangible_p): Reimplement to call
20126 handle_display_spec instead of single_display_spec_intangible_p.
20127 Accept 3 additional arguments needed by handle_display_spec.
20128 This fixes incorrect cursor motion across display property with complex
20129 values: lists, `(when COND...)' forms, etc.

20131 lists with the argument STRING its top-level element.
20132 (display_prop_string_p): Fix the condition for processing a
20133 property that is a list to be consistent with handle_display_spec.

20135 last portion of handle_display_prop.
20136 (compute_display_string_pos): Accept additional argument
20137 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20138 value of a `display' property is a "replacing spec".
20139 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20140 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20141 the display property, but just return a value indicating whether
20142 the display property will replace the characters it covers.
20143 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20144 frame_window_p members of struct bidi_it.
20145 (compute_display_string_pos, compute_display_string_end):
20147 (push_it): Accept second argument POSITION, where pop_it should
20148 jump to continue iteration.
20149 (reseat_1): Initialize bidi_it.disp_pos.
20151 * keyboard.c (adjust_point_for_property): Adjust the call to
20152 display_prop_intangible_p to its new signature.
20154 * dispextern.h (struct bidi_it): New member frame_window_p.
20155 (bidi_init_it): Update prototypes.

20165 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
20166 * lisp.h: Change signatures accordingly.
20167 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
20168 All callers changed. (Bug#8762)
20170 * gnutls.c: Use Emacs's memory allocators.
20171 Without this change, the gnutls library would invoke malloc etc.
20172 directly, which causes problems on non-SYNC_INPUT hosts, and which
20173 runs afoul of improving memory_full behavior. (Bug#8761)
20174 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20175 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20176 xfree instead of the default malloc, realloc, free.
20177 (Fgnutls_boot): No need to check for memory allocation failure,
20178 since xmalloc does that for us.
20180 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
20181 * category.c (hash_get_category_set):
20182 * ccl.c (ccl_driver):

20195 (Fsxhash, Fgethash, Fputhash, Fmaphash):
20196 * image.c (make_image, search_image_cache, lookup_image)
20197 (xpm_put_color_table_h):
20198 * lisp.h (struct Lisp_Hash_Table):
20199 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20200 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20201 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20202 * alloc.c (allocate_vectorlike):
20203 Check for overflow in vector size calculations.
20204 * ccl.c (ccl_driver):
20205 Check for overflow when converting EMACS_INT to int.
20206 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20207 need to be updated by these changes.
20208 * fns.c (make_hash_table, maybe_resize_hash_table):
20209 Check for integer overflow with large hash tables.
20210 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20211 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20212 (SXHASH_REDUCE): New macro.
20213 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20214 Use it instead of discarding useful hash info with large hash values.
20215 (sxhash_float): New function.
20216 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20217 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20218 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20219 Rewrite to use FIXNUM_BITS, as this simplifies things.
20220 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20221 Adjust signatures to match updated version of code.
20222 (consing_since_gc): Now EMACS_INT, since a single hash table can
20223 use more than INT_MAX bytes.
20225 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20227 Make it possible to build with GCC-4.6+ -O2 -flto.
20229 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20231 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20233 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20234 Call minibuffer-inactive-mode.
20236 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20238 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20239 Update dependencies.
20241 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20243 * data.c (init_data): Remove code for UTS, this system is not
20246 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20248 Don't force ./temacs to start in terminal mode.
20250 * frame.c (make_initial_frame): Initialize faces in all cases, not
20251 only when CANNOT_DUMP is defined.
20252 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20254 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20256 * dispnew.c (add_window_display_history): Use const for the string
20257 pointer. Remove declaration, not needed.
20259 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20261 Use 'inline', not 'INLINE'.
20262 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20263 * alloc.c, fontset.c (INLINE): Remove.
20264 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20265 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20266 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20267 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20268 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20270 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20272 Make it possible to run ./temacs.
20274 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20275 syms_of_callproc does the same thing. Remove test for
20276 "initialized", do it in the caller.
20277 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20279 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20281 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20282 (read_minibuf): Use get_minibuffer.
20283 (syms_of_minibuf): Use DEFSYM.
20284 (Qmetadata): New var.
20285 * data.c (Qbuffer): Don't make it static.
20286 (syms_of_data): Use DEFSYM.
20288 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20290 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20291 (CCL_CODE_MIN): New macro.
20293 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20295 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20297 * eval.c (Qdebug): Now static.
20298 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20299 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20300 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20302 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20304 * image.c: Various fixes to ImageMagick code comments.
20305 (Fimagemagick_types): Doc fix.
20307 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20309 Minor fixes prompted by GCC 4.6.0 warnings.
20311 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20313 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20314 (x_clipboard_manager_save_all): Move extern decl to ...
20315 * xterm.h: ... here, so that it can be checked for consistency.
20317 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20319 * xselect.c (x_clipboard_manager_save_frame)
20320 (x_clipboard_manager_save_all): New functions.
20321 (Fx_clipboard_manager_save): Lisp function deleted.
20323 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20324 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20326 * xterm.h: Update prototype.
20328 2011-05-28 William Xu <william.xwl@gmail.com>
20330 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20331 exiting (Bug#8239).
20333 2011-05-28 Jim Meyering <meyering@redhat.com>
20335 Avoid a sign-extension bug in crypto_hash_function.
20336 * fns.c (to_uchar): Define.
20337 (crypto_hash_function): Use it to convert some newly-signed
20338 variables to unsigned, to avoid sign-extension bugs. For example,
20339 without this change, (md5 "truc") would evaluate to
20340 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20341 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20342 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20344 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20346 Integer overflow fixes.
20348 * dbusbind.c: Serial number integer overflow fixes.
20349 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20350 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20351 to hold a serial number that is too large for a fixnum.
20352 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20353 Check for serial numbers out of range. Decode any serial number
20354 that was so large that it became a float. (Bug#8722)
20356 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20357 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20358 Use XFASTINT rather than XUINT when numbers are nonnegative.
20359 (xd_append_arg, Fdbus_method_return_internal):
20360 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20361 arguments, check that Lisp number is nonnegative, rather than
20362 silently wrapping negative numbers around. (Bug#8722)
20363 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20366 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20368 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20370 ccl: Add integer overflow checks.
20371 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20372 (IN_INT_RANGE): New macros.
20373 (ccl_driver): Use them to check for integer overflow when
20374 decoding a CCL program. Many of the new checks are whether XINT (x)
20375 fits in int; it doesn't always, on 64-bit hosts. The new version
20376 doesn't catch all possible integer overflows, but it's an
20377 improvement. (Bug#8719)
20379 * alloc.c (make_event_array): Use XINT, not XUINT.
20380 There's no need for unsigned here.
20382 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20383 This follows up to the 2011-05-06 change that substituted uintptr_t
20384 for EMACS_INT. This case wasn't caught back then.
20386 Rework Fformat to avoid integer overflow issues.
20387 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20388 now (part of C89). Include <verify.h>.
20389 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20390 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20391 (Fformat): Avoid the prepass trying to compute sizes; it was only
20392 approximate and thus did not catch overflow reliably. Instead, walk
20393 through the format just once, formatting and computing sizes as we go,
20394 checking for integer overflow at every step, and allocating a larger
20395 buffer as needed. Keep track separately whether the format is
20396 multibyte. Keep only the most-recently calculated precision, rather
20397 than them all. Record whether each argument has been converted to
20398 string. Use EMACS_INT, not int, for byte and char and arg counts.
20399 Support field widths and precisions larger than INT_MAX. Avoid
20400 sprintf's undefined behavior with conversion specifications such as %#d
20401 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20402 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20403 formatting out-of-range floating point numbers with int
20404 formats. (Bug#8668)
20406 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20408 * data.c: Avoid integer truncation in expressions involving floats.
20409 * data.c: Include <intprops.h>.
20410 (arith_driver): When there's an integer overflow in an expression
20411 involving floating point, convert the integers to floating point
20412 so that the resulting value does not suffer from catastrophic
20413 integer truncation. For example, on a 64-bit host (* 4
20414 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20415 Do not rely on undefined behavior after integer overflow.
20417 merge count_size_as_multibyte, parse_str_to_multibyte
20418 * character.c, character.h (count_size_as_multibyte):
20419 Rename from parse_str_to_multibyte; all uses changed.
20420 Check for integer overflow.
20421 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20422 since it's now a duplicate of the other. This is more of
20423 a character than a buffer op, so better that it's in character.c.
20424 * fns.c, print.c: Adjust to above changes.
20426 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20428 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20430 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20432 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20433 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20434 (x_clipboard_manager_save): Now static.
20435 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20437 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20438 (crypto_hash_function): Now static.
20439 Fix pointer signedness problems. Avoid unnecessary initializations.
20441 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20443 * termhooks.h (Vselection_alist): Make it terminal-local.
20445 * terminal.c (create_terminal): Initialize it.
20447 * xselect.c: Support for clipboard managers.
20448 (Vselection_alist): Move to termhooks.h as terminal-local var.
20449 (LOCAL_SELECTION): New macro.
20450 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20451 (symbol_to_x_atom): Remove gratuitous arg.
20452 (x_handle_selection_request, lisp_data_to_selection_data)
20453 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20454 (x_own_selection, x_get_local_selection, x_convert_selection):
20455 New arg, specifying work frame. Use terminal-local Vselection_alist.
20456 (some_frame_on_display): Delete unused function.
20457 (Fx_own_selection_internal, Fx_get_selection_internal)
20458 (Fx_disown_selection_internal, Fx_selection_owner_p)
20459 (Fx_selection_exists_p): New optional frame arg.
20460 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20461 (x_handle_selection_clear): Don't treat other terminals with the
20462 same keyboard specially. Use the terminal-local Vselection_alist.
20463 (x_clear_frame_selections): Use Frun_hook_with_args.
20465 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20467 * xterm.h: Add support for those atoms.
20469 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20471 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20472 (converted_selections, conversion_fail_tag): New global variables.
20473 (x_selection_request_lisp_error): Free the above.
20474 (x_get_local_selection): Remove unnecessary code.
20475 (x_reply_selection_request): Args changed; handle arbitrary array
20476 of converted selections stored in converted_selections.
20477 Separate the XChangeProperty and SelectionNotify steps.
20478 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20479 (x_convert_selection): New function.
20480 (x_handle_selection_event): Simplify.
20481 (x_get_foreign_selection): Don't ignore incoming requests while
20482 waiting for an answer; this will fail when we implement
20483 SAVE_TARGETS, and seems unnecessary anyway.
20484 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20485 (Vx_sent_selection_functions): Doc fix.
20487 2011-05-26 Leo Liu <sdl.web@gmail.com>
20489 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20491 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20493 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20495 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20496 for fringe update if it has periodic bitmap.
20497 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20498 and fringe_bitmap_periodic_p.
20500 * fringe.c (get_fringe_bitmap_data): New function.
20501 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20502 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20503 row. Mark glyph row for fringe update if periodicity changed.
20505 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20506 for fringe update unless it has periodic bitmap.
20508 2011-05-25 Kenichi Handa <handa@m17n.org>
20510 * xdisp.c (get_next_display_element): Set correct it->face_id for
20511 a static composition.
20513 2011-05-24 Leo Liu <sdl.web@gmail.com>
20516 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20518 * fns.c (crypto_hash_function, Fsha1): New function.
20519 (Fmd5): Use crypto_hash_function.
20520 (syms_of_fns): Add Ssha1.
20522 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20524 * gnutls.c: Remove unused macros.
20525 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20526 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20527 Remove macros that are defined and never used.
20528 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20530 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20532 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20533 (Fx_get_selection_internal): Minor cleanup.
20534 (Fx_own_selection_internal): Rename arguments for consistency with
20537 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20539 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20541 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20543 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20545 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20547 * dispnew.c (scrolling_window): Don't exclude the case that the
20548 last enabled row in the desired matrix touches the bottom boundary.
20550 2011-05-21 Glenn Morris <rgm@gnu.org>
20552 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20553 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20554 and add some more files.
20556 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20558 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20559 report_file_error introduced by the change from 2011-05-07.
20561 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20563 * systime.h (Time): Define only if emacs is defined.
20564 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20565 where the include path doesn't have X11/X.h by default. See
20566 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20568 2011-05-20 Kenichi Handa <handa@m17n.org>
20570 * composite.c (find_automatic_composition): Fix previous change.
20572 2011-05-20 Glenn Morris <rgm@gnu.org>
20574 * lisp.mk: New file, split from Makefile.in.
20575 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20576 (shortlisp): Remove.
20577 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20579 2011-05-19 Glenn Morris <rgm@gnu.org>
20581 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20582 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20583 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20584 (lisp): Set the order to that of loadup.el.
20585 (shortlisp): Make it a copy of $lisp.
20586 (SOME_MACHINE_LISP): Remove.
20587 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20588 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20590 2011-05-18 Kenichi Handa <handa@m17n.org>
20592 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20593 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20594 (find_automatic_composition): Mostly rewrite for efficiency.
20596 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20598 * makefile.w32-in: Update dependencies.
20600 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20602 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20603 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20605 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20607 Fix some integer overflow issues, such as string length overflow.
20609 * insdel.c (count_size_as_multibyte): Check for string overflow.
20611 * character.c (lisp_string_width): Check for string overflow.
20612 Use EMACS_INT, not int, for string indexes and lengths; in
20613 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20614 the resulting string length overflows an EMACS_INT; instead,
20615 report a string overflow if no precision given. When checking for
20616 precision exhaustion, use a check that cannot possibly have
20617 integer overflow. (Bug#8675)
20618 * character.h (lisp_string_width): Adjust to new signature.
20620 * alloc.c (string_overflow): New function.
20621 (Fmake_string): Use it. This doesn't change behavior, but saves
20622 a few bytes and will simplify future changes.
20623 * character.c (string_escape_byte8): Likewise.
20624 * lisp.h (string_overflow): New decl.
20626 Fixups, following up to the user-interface timestamp change.
20627 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20628 for UI timestamps, instead of unsigned long.
20629 * msdos.c (mouse_get_pos): Likewise.
20630 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20631 * w32gui.h (Time): Define by including "systime.h" rather than by
20632 declaring it ourselves. (Bug#8664)
20634 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20635 * image.c (clear_image_cache): Likewise.
20637 * term.c (term_mouse_position): Don't assume time_t wraparound.
20639 Be more systematic about user-interface timestamps.
20640 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20641 and sometimes 'EMACS_UINT', to represent these timestamps.
20642 This change causes it to use 'Time' uniformly, as that's what X uses.
20643 This makes the code easier to follow, and makes it easier to catch
20644 integer overflow bugs such as Bug#8664.
20645 * frame.c (Fmouse_position, Fmouse_pixel_position):
20646 Use Time, not unsigned long, for user-interface timestamps.
20647 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20648 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20649 * keyboard.h (last_event_timestamp): Likewise.
20650 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20651 * menu.h (xmenu_show): Likewise.
20652 * term.c (term_mouse_position): Likewise.
20653 * termhooks.h (struct input_event.timestamp): Likewise.
20654 (struct terminal.mouse_position_hook): Likewise.
20655 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20656 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20657 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20658 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20659 what it was before.
20660 * menu.h, termhooks.h: Include "systime.h", for Time.
20662 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20663 Don't assume that the difference between two unsigned long values
20664 can fit into an integer. At this point, we know button_down_time
20665 <= event->timestamp, so the difference must be nonnegative, so
20666 there's no need to cast the result if double-click-time is
20667 nonnegative, as it should be; check that it's nonnegative, just in
20668 case. This bug is triggered when events are more than 2**31 ms
20669 apart (about 25 days). (Bug#8664)
20671 * xselect.c (last_event_timestamp): Remove duplicate decl.
20672 (x_own_selection): Remove needless cast to unsigned long.
20674 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20675 that always fit in int. Use a sentinel instead of a counter, to
20676 avoid a temp and to allay GCC's concerns about possible int overflow.
20677 * frame.h (struct frame): Use int for menu_bar_items_used
20678 instead of EMACS_INT, since it always fits in int.
20680 * menu.c (grow_menu_items): Check for int overflow.
20682 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20684 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20685 Before, the code was not consistent. These values cannot exceed
20686 2**31 - 1 so there's no need to make them unsigned.
20687 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20688 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20689 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20691 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20693 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20694 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20695 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20696 presumably because the widths might not match.
20698 * window.c (size_window): Avoid needless test at loop start.
20700 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20702 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20704 2011-05-12 Drew Adams <drew.adams@oracle.com>
20706 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20708 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20710 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20711 `width' to `bar_area_x' and `bar_area_width', respectively.
20712 (x_scroll_run): Take account of fringe background extension.
20714 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20715 Rename local vars `left' and `width' to `bar_area_x' and
20716 `bar_area_width', respectively.
20717 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20718 background extension.
20720 2011-05-10 Jim Meyering <meyering@redhat.com>
20722 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20724 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20726 * image.c (Finit_image_library): Return t for built-in image types,
20727 like pbm and xbm. (Bug#8640)
20729 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20731 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20733 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20735 * w32console.c (Fset_screen_color): Doc fix.
20736 (Fget_screen_color): New function.
20737 (syms_of_ntterm): Defsubr it.
20739 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20740 unlink the temporary file if Fcall_process didn't create it in the
20742 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20743 child process will be redirected to a file specified with `:file'.
20744 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20745 cue to call_process_cleanup not to close that handle.
20747 2011-05-07 Ben Key <bkey76@gmail.com>
20749 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20750 one of two shell specific rules, either bootstrap-temacs-CMD or
20751 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20752 to the previous implementation of the bootstrap-temacs rule.
20753 The bootstrap-temacs-CMD rule is similar to the previous
20754 implementation of the bootstrap-temacs rule except that it
20755 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20758 These changes, along with some changes to nt/configure.bat,
20759 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20760 earlier fix to add support for --cflags and --ldflags options
20761 that include quotes so that it works whether make uses cmd or
20764 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20766 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20767 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20769 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20770 a string. Handle both cases.
20771 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20772 (Fdbus_register_method): Use Qinvalid_function.
20774 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20776 * makefile.w32-in: Update dependencies.
20777 (LISP_H): Add inttypes.h and stdin.h.
20778 (PROCESS_H): Add unistd.h.
20780 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20782 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20783 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20785 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20787 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20789 * term.c (vfatal): Remove stray call to va_end.
20790 It's not needed and the C Standard doesn't allow it here anyway.
20792 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20793 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20795 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20798 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20800 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20802 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20804 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20806 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20808 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20809 * charset.c (Fdefine_charset_internal): Don't initialize
20810 charset.code_space[15]. The value was garbage, on hosts with
20811 32-bit int (Bug#8600).
20813 * lread.c (read_integer): Be more consistent with string-to-number.
20814 Use string_to_number to do the actual conversion; this avoids
20815 rounding errors and fixes some other screwups. Without this fix,
20816 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20817 (digit_to_number): Move earlier, for benefit of read_integer.
20818 Return -1 if the digit is out of range for the base, -2 if it is
20819 not a digit in any supported base. (Bug#8602)
20821 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20823 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20824 to match comment at start of function. This also removes a
20825 GCC warning about overflow in a 32+64-bit port.
20827 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20829 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20830 Reported by Stefan Monnier in
20831 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20832 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20833 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20835 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20836 (EMACS_UINTPTR): Likewise, with uintptr_t.
20838 * lisp.h: Prefer 64-bit EMACS_INT if available.
20839 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20840 on 32-bit hosts that have 64-bit int, so that they can access
20842 However, temporarily disable this change unless the temporary
20843 symbol WIDE_EMACS_INT is defined.
20845 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20847 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20848 This removes an assumption that EMACS_INT and long are the same
20849 width as pointers. The assumption is true for Emacs porting targets
20850 now, but we want to make other targets possible.
20851 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20852 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20853 In the rest of the code, change types of integers that hold casted
20854 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20855 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20856 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20857 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20858 No need to cast type when ORing.
20859 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20860 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20861 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20862 assume EMACS_INT is the same width as char *.
20863 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20864 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20865 Remove no-longer-needed casts.
20866 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20867 (xg_tool_bar_help_callback, xg_make_tool_item):
20868 Use EMACS_INTPTR to hold an integer
20869 that will be cast to void *; this can avoid a GCC warning
20870 if EMACS_INT is not the same width as void *.
20871 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20872 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20873 (current_message_1, set_message_1):
20874 Use a local to convert to proper width without a cast.
20875 * xmenu.c (dialog_selection_callback): Likewise.
20877 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20878 Also, don't assume VALBITS / RAND_BITS is less than 5,
20879 and don't rely on undefined behavior when shifting a 1 left into
20881 * lisp.h (get_random): Change signature to match.
20883 * lread.c (hash_string): Use size_t, not int, for hash computation.
20884 Normally we prefer signed values; but hashing is special, because
20885 it's better to use unsigned division on hash table sizes so that
20886 the remainder is nonnegative. Also, size_t is the natural width
20887 for hashing into memory. The previous code used 'int', which doesn't
20888 retain enough info to hash well into very large tables.
20889 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20891 * dbusbind.c: Don't possibly lose pointer info when converting.
20892 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20893 Use XPNTR rather than XHASH, so that the high-order bits of
20894 the pointer aren't lost when converting through void *.
20896 * eval.c (Fautoload): Don't double-shift a pointer.
20898 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20900 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20902 * gnutls.c (DEF_GNUTLS_FN):
20903 * image.c (DEF_IMGLIB_FN): Make function pointers static.

20907 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20910 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20912 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20913 New version that can reserve upto 2GB of heap space.
20915 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20917 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

20921 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to

20927 Update dependencies.
20929 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20931 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20932 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20933 Remove unused parameter `fildes'.
20934 * process.c (read_process_output, send_process): Don't pass it.
20936 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20938 Fix previous change: the library cache is defined in w32.c.
20939 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20940 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20942 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20944 Implement dynamic loading of GnuTLS on Windows.
20946 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20947 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20948 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):

20961 (Fgnutls_available_p): New function.
20962 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

20972 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20974 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20975 (w32_delayed_load): Move from image.c. When loading a library, record
20976 its filename in the :loaded-from property of the library id.
20977 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20978 Initialize and staticpro them.
20979 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20981 * process.c: Include lisp.h before w32.h, not after.
20982 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20983 instead of gnutls_record_check_pending.
20985 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20987 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20989 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20990 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20993 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20995 * xterm.c (x_set_frame_alpha): Do not set property on anything
20996 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20998 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21000 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
21002 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
21004 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
21005 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

21024 * sysdep.c (interruptible_wait_for_termination): New function
21025 which is like wait_for_termination, but allows keyboard
21028 * callproc.c (Fcall_process): Add (:file "file") as an option for
21030 (Fcall_process_region): Ditto.
21032 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21034 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21035 rather than `XVECTOR (FOO)->size'.
21037 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21038 inttypes.h, as a gnulib replacement is used if it not available in
21041 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21043 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21044 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21045 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21047 * coding.c (coding_alloc_by_realloc): Error out if destination
21048 will grow beyond MOST_POSITIVE_FIXNUM.
21049 (decode_coding_emacs_mule): Abort if there isn't enough place in
21050 charbuf for the composition carryover bytes. Reserve an extra
21051 space for up to 2 characters produced in a loop.
21052 (decode_coding_iso_2022): Abort if there isn't enough place in
21053 charbuf for the composition carryover bytes.
21055 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21057 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
21058 aborting when %lld or %lll format is passed.
21059 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21060 %llo or %llx format is passed. (Bug#8545)
21062 * window.c (window_scroll_line_based): Use a marker instead of
21063 simple variables to record original value of point. (Bug#7952)
21065 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21066 produced by %s or %c overflows available buffer space. (Bug#8545)
21068 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21070 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

21079 * keyboard.c (Qdelayed_warnings_hook): Define.
21080 (command_loop_1): Run `delayed-warnings-hook'
21081 if Vdelayed_warnings_list is non-nil.
21082 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21083 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21085 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21087 * doprnt.c (doprnt): Don't return value smaller than the buffer
21088 size if the message was truncated. (Bug#8545).
21090 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21092 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21093 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21095 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21097 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21099 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21101 * makefile.w32-in: Update dependencies.
21103 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21105 Improve `doprnt' and its usage. (Bug#8545)
21106 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21107 `format_end'. Remove support for %l as a conversion specifier.
21108 Don't use xrealloc. Improve diagnostics when the %l size modifier
21109 is used. Update the commentary.
21111 * eval.c (verror): Simplify calculation of size_t.
21113 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21116 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21118 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21121 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21123 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21124 This makes this file independent of the recent pseudovector change.
21126 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21128 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21130 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21131 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21132 Remove unused local.
21133 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21135 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21136 GCC 4.6.0 optimizes based on type-based alias analysis.
21137 For example, if b is of type struct buffer * and v of type struct
21138 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21139 != &v->size, and therefore "v->size = 1; b->size = 2; return
21140 v->size;" must therefore return 1. This assumption is incorrect
21141 for Emacs, since it type-puns struct Lisp_Vector * with many other
21142 types. To fix this problem, this patch adds a new type struct
21143 vectorlike_header that documents the constraints on layout of vectors
21144 and pseudovectors, and helps optimizing compilers not get fooled
21145 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21146 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21147 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21149 (XSETPVECTYPE): Rewrite in terms of new macro.
21150 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21151 This is a bit clearer, and further avoids the possibility of
21152 undesirable aliasing.
21153 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21154 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21155 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21156 since Lisp_Subr is a special case (no "next" field).
21157 (ASIZE): Now uses header.size rather than size.
21158 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21159 to avoid the hassle of writing XVECTOR (foo)->header.size.
21160 (struct vectorlike_header): New type.
21161 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21162 object, to help avoid aliasing.
21163 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21164 (SUBRP): Likewise, since Lisp_Subr is a special case.
21165 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21166 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21167 (struct Lisp_Hash_Table): Combine first two members into a single
21168 struct vectorlike_header member. All uses of "size" and "next" members
21169 changed to be "header.size" and "header.next".
21170 * buffer.h (struct buffer): Likewise.
21171 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21172 * frame.h (struct frame): Likewise.
21173 * process.h (struct Lisp_Process): Likewise.
21174 * termhooks.h (struct terminal): Likewise.
21175 * window.c (struct save_window_data, struct saved_window): Likewise.
21176 * window.h (struct window): Likewise.
21177 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21178 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21179 * buffer.c (init_buffer_once): Likewise.
21180 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21182 * process.c (Fformat_network_address): Use local var for size,
21185 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21187 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21188 * data.c (atof): Remove decl; no longer used or needed.
21189 (digit_to_number): Move to lread.c.
21190 (Fstring_to_number): Use new string_to_number function, to be
21191 consistent with how the Lisp reader treats infinities and NaNs.
21192 Do not assume that floating-point numbers represent EMACS_INT
21193 without losing information; this is not true on most 64-bit hosts.
21194 Avoid double-rounding errors, by insisting on integers when
21195 parsing non-base-10 numbers, as the documentation specifies.
21196 * lisp.h (string_to_number): New decl, replacing ...
21197 (isfloat_string): Remove.
21198 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21199 (read1): Do not accept +. and -. as integers; this
21200 appears to have been a coding error. Similarly, do not accept
21201 strings like +-1e0 as floating point numbers. Do not report
21202 overflow for integer overflows unless the base is not 10 which
21203 means we have no simple and reliable way to continue.
21204 Break out the floating-point parsing into a new
21205 function string_to_number, so that Fstring_to_number parses
21206 floating point numbers consistently with the Lisp reader.
21207 (digit_to_number): Move here from data.c. Make it static inline.
21208 (E_CHAR, EXP_INT): Remove, replacing with ...
21209 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21210 (string_to_number): New function, replacing isfloat_string.
21211 This function checks for valid syntax and produces the resulting
21212 Lisp float number too. Rework it so that string-to-number
21213 no longer mishandles examples like "1.0e+". Use strtoumax,
21214 so that overflow for non-base-10 numbers is reported only when
21215 there's no portable and simple way to convert to floating point.
21217 * textprop.c (set_text_properties_1): Rewrite for clarity,
21218 and to avoid GCC warning about integer overflow.
21220 * intervals.h (struct interval): Use EMACS_INT for members
21221 where EMACS_UINT might cause problems. See
21222 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21223 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21224 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21226 (offset_intervals): Tell GCC not to worry about length overflow
21227 when negating a negative length.
21229 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21230 (overrun_check_free): Likewise.
21232 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21233 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21236 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21237 (gnutls_make_error): Rename local to avoid shadowing.
21238 (gnutls_emacs_global_deinit): ifdef out; not used.
21239 (Fgnutls_boot): Use const for pointer to readonly storage.
21240 Comment out unused local. Fix pointer signedness problems.
21242 * lread.c (openp): Don't stuff size_t into an 'int'.
21243 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21244 about possible signed overflow.
21246 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21247 (GDK_KEY_g): Don't define if already defined.
21248 (xg_prepare_tooltip): Avoid pointer signedness problem.
21249 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21251 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21252 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21254 * xfns.c (Fx_window_property): Simplify a bit,
21255 to make a bit faster and to avoid GCC 4.6.0 warning.
21256 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21258 * fns.c (internal_equal): Don't assume size_t fits in int.
21260 * alloc.c (compact_small_strings): Tighten assertion a little.
21262 Replace pEd with more-general pI, and fix some printf arg casts.
21263 * lisp.h (pI): New macro, generalizing old pEd macro to other
21264 conversion specifiers. For example, use "...%"pI"d..." rather
21265 than "...%"pEd"...".
21266 (pEd): Remove. All uses replaced with similar uses of pI.
21267 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21268 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21269 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21270 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21271 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21272 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21273 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21275 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21276 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21277 * print.c (safe_debug_print, print_object): Likewise.
21278 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21280 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21281 avoiding the 0 flag, which is not portable.
21282 * process.c (Fmake_network_process): Use pI to avoid cast.
21283 * region-cache.c (pp_cache): Likewise.
21284 * xdisp.c (decode_mode_spec): Likewise.
21285 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21286 behavior on 64-bit hosts with printf arg.
21287 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21288 (x_stop_queuing_selection_requests): Likewise.
21289 (x_get_window_property): Don't truncate byte count to an 'int'
21292 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21293 here, since it parses constructs like leading '-' and spaces,
21294 which are not wanted; and it overflows with large numbers.
21295 Instead, simply match F[0-9]+, which is what is wanted anyway.
21297 * alloc.c: Remove unportable assumptions about struct layout.
21298 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21299 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21300 (allocate_vectorlike, make_pure_vector): Use the new macros,
21301 plus offsetof, to remove unportable assumptions about struct layout.
21302 These assumptions hold on all porting targets that I know of, but
21303 they are not guaranteed, they're easy to remove, and removing them
21304 makes further changes easier.
21306 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21307 This doesn't fix a bug but makes the code clearer.
21308 (string_overrun_cookie): Now const. Use initializers that
21309 don't formally overflow signed char, to avoid warnings.
21310 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21311 can cause Emacs to crash when string overrun checking is enabled.
21312 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21313 multiple of sizeof (EMACS_INT); it need not be, if
21314 alignof(EMACS_INT) < sizeof (EMACS_INT).
21315 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21317 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21346 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21347 "cast to pointer from integer of different size".
21349 Improve doprnt and its use in verror. (Bug#8545)
21350 * doprnt.c (doprnt): Document the set of format control sequences
21351 supported by the function. Use SAFE_ALLOCA instead of always
21354 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21355 is one byte too soon. Don't use xrealloc; instead xfree and
21358 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21360 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

21365 :verify-hostname-error, :verify-error, and :verify-flags
21366 parameters of `gnutls-boot' and documented those parameters in the
21367 docstring. Start callback support.
21368 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21369 unless a fatal error occurred. Call gnutls_alert_send_appropriate

21467 * callint.c (Fcall_interactively): When displaying error message
21468 about invalid control letter, pass the character's codepoint, not

21473 codepoint of an invalid character, to avoid displaying a bogus
21476 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21477 `error', not SYMBOL_NAME itself.
21479 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

21482 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21483 to `error' in error message about FINAL_CHAR argument. Make sure
21484 FINAL_CHAR is a character, and use %c when it is passed as
21485 argument to `error'.
21487 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21489 * s/ms-w32.h (localtime): Redirect to sys_localtime.
21491 * w32.c: Include <time.h>.

21555 * dispextern.h (struct redisplay_interface): Rename param
21556 to avoid shadowing.
21557 * termhooks.h (struct terminal): Likewise.

21674 * nsfont.m: Fixed bugs in ns_get_family and
21675 ns_descriptor_to_entity that were caused by using free to
21676 deallocate memory blocks that were allocated by xmalloc (via
21677 xstrdup). This caused Emacs to crash when compiled with
21678 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21679 --enable-checking=xmallocoverrun). xfree is now used to
21680 deallocate these memory blocks.

21694 (emacs_read, emacs_write): Remove check for negative size, as the
21695 Emacs source code has been audited now.
21696 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
21697 (emacs_read, emacs_write): Use it.
21698 * process.c (send_process): Adjust to the new signatures of
21699 emacs_write and emacs_gnutls_write. Do not attempt to store
21700 a byte offset into an 'int'; it might overflow.
21701 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

21727 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>
21729 Improve C-level modularity by making more things 'static'.
21731 Don't publish debugger-only interfaces to other modules.

22143 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
22145 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
22148 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22150 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22151 when at ZV. (Bug#8487)
22153 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22155 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22157 * keyboard.c (parse_tool_bar_item): Likewise.
22158 * sound.c (sound_cleanup, alsa_close): Likewise.
22159 * termcap.c (tgetent): Likewise.
22160 * xfns.c (x_default_font_parameter): Likewise.
22161 * xsettings.c (read_and_apply_settings): Likewise.
22163 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22164 (overrun_check_free): Protoize.
22166 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22168 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22169 since callers should never pass a negative size.
22170 Change the signature to match that of plain 'read' and 'write'; see
22171 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22172 * lisp.h: Update prototypes of emacs_write and emacs_read.
22174 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22176 * xdisp.c (redisplay_window): Don't try to determine the character
22177 position of the scroll margin if the window start point w->startp
22178 is outside the buffer's accessible region. (Bug#8468)
22180 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22182 Fix write-region and its subroutines for buffers > 2GB.
22183 * fileio.c (a_write, e_write): Modify declaration of arguments and
22184 local variables to support buffers larger than 2GB.
22185 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22187 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22188 argument, local variables, and return value.
22190 * lisp.h: Update prototypes of emacs_write and emacs_read.
22192 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22194 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22196 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22198 Fix more problems found by GCC 4.6.0's static checks.
22200 * xdisp.c (vmessage): Use a better test for character truncation.
22202 * charset.c (load_charset_map): <, not <=, for optimization,
22203 and to avoid potential problems with integer overflow.
22204 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22205 * casetab.c (set_identity, shuffle): Likewise.
22206 * editfns.c (Fformat): Likewise.
22207 * syntax.c (skip_chars): Likewise.
22209 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22210 This also lets GCC 4.6.0 generate slightly better loop code.
22212 * callint.c (Fcall_interactively): <, not <=, for optimization.
22213 (Fcall_interactively): Count the number of arguments produced,
22214 not the number of arguments given. This is simpler and lets GCC
22215 4.6.0 generate slightly better code.
22217 * ftfont.c: Distingish more carefully between FcChar8 and char.
22218 The previous code passed unsigned char * to a functions like
22219 strlen and xstrcasecmp that expect char *, which does not
22220 conform to the C standard.
22221 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22222 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22223 char * when the C standard requires it.
22225 * keyboard.c (read_char): Remove unused var.
22227 * eval.c: Port to Windows vsnprintf (Bug#8435).
22228 Include <limits.h>.
22229 (SIZE_MAX): Define if the headers do not.
22230 (verror): Do not give up if vsnprintf returns a negative count.
22231 Instead, grow the buffer. This ports to Windows vsnprintf, which
22232 does not conform to C99. Problem reported by Eli Zaretskii.
22233 Also, simplify the allocation scheme, by avoiding the need for
22234 calling realloc, and removing the ALLOCATED variable.
22236 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22238 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22239 But keep the doprint source code for now, as we might revamp it
22240 and use it again (Bug#8435).
22241 * lisp.h (doprnt): Remove.
22242 * Makefile.in (base_obj): Remove doprnt.o.
22243 * deps.mk (doprnt.o): Remove.
22245 error: Print 32- and 64-bit integers portably (Bug#8435).
22246 Without this change, on typical 64-bit hosts error ("...%d...", N)
22247 was used to print both 32- and 64-bit integers N, which relied on
22248 undefined behavior.
22249 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22250 * lisp.h (error, verror): Mark as printf-like functions.
22251 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22252 Report overflow in size calculations when allocating printf buffer.
22253 Do not truncate output string at its first null byte.
22254 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22255 Truncate the output at a character boundary, since vsnprintf does not
22257 * charset.c (check_iso_charset_parameter): Convert internal
22258 character to string before calling 'error', since %c now has the
22260 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22261 overflow when computing char to be passed to 'error'. Do not
22262 pass Lisp_Object to 'error'; pass the integer instead.
22263 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22264 formatted with plain %d.
22266 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22268 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22270 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22272 * xterm.c (x_catch_errors): Remove duplicate declaration.
22274 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22276 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22278 2011-04-10 Jim Meyering <meyering@redhat.com>
22280 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22281 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22282 return ssize_t not "int", and use size_t as the buffer length.
22283 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22284 * gnutls.h: Update declarations.
22285 * process.c (read_process_output): Use ssize_t, to match.
22286 (send_process): Likewise.
22288 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22290 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22292 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22294 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22295 Use unsigned char, to match FcChar8 type definition.
22297 * xterm.c (handle_one_xevent):
22298 * xmenu.c (create_and_show_popup_menu):
22299 * xselect.c (x_decline_selection_request)
22300 (x_reply_selection_request): Avoid type-punned deref of X events.
22302 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22304 Fix some uses of `int' instead of EMACS_INT.
22305 * search.c (string_match_1, fast_string_match)
22306 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22307 (scan_buffer, find_next_newline_no_quit)
22308 (find_before_next_newline, search_command, Freplace_match)
22309 (Fmatch_data): Make some `int' variables be EMACS_INT.
22311 * xdisp.c (display_count_lines): 3rd argument and return value now
22312 EMACS_INT. All callers changed.
22313 (pint2hrstr): Last argument is now EMACS_INT.
22315 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22316 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22317 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22318 (decode_coding_utf_16, decode_coding_emacs_mule)
22319 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
22320 (decode_coding_ccl, decode_coding_charset)
22321 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22322 (decode_coding_iso_2022, decode_coding_emacs_mule)
22323 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22324 <char_offset, last_offset>: Declare EMACS_INT.
22325 (encode_coding_utf_8, encode_coding_utf_16)
22326 (encode_coding_emacs_mule, encode_invocation_designation)
22327 (encode_designation_at_bol, encode_coding_iso_2022)
22328 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22329 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22331 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22332 (encode_invocation_designation): Last argument P_NCHARS is now
22334 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22335 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22337 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22340 * ccl.c (Fccl_execute_on_string): Declare some variables
22343 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22345 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22347 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22349 * process.c (Fformat_network_address): Doc fix.
22351 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22353 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22355 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22357 * keyboard.c (read_char): Call Lisp function help-form-show,
22358 instead of using internal_with_output_to_temp_buffer.
22359 (Qhelp_form_show): New var.
22360 (syms_of_keyboard): Use DEFSYM macro.
22362 * print.c (internal_with_output_to_temp_buffer): Function deleted.
22364 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
22366 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22368 * process.c (Flist_processes): Remove to Lisp.
22369 (list_processes_1): Delete.
22371 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22373 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22375 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22377 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22379 Fix more problems found by GCC 4.6.0's static checks.

22383 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22385 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22387 * xdisp.c (vmessage): Mark as a printf-like function.
22389 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22391 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22393 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22394 printf-like functions.
22395 (tiff_load): Add casts to remove these marks before passing them
22396 to system-supplied API.
22398 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22400 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22401 This avoids several warnings with gcc -Wstrict-overflow.
22402 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22403 directly, rather than having caller test rule sign. This avoids
22404 some unnecessary tests.
22405 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22406 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22407 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22409 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22410 (xfont_open): Avoid unnecessary tests.
22412 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22414 * composite.h, composite.c (composition_gstring_put_cache):
22415 Use EMACS_INT, not int, for length.

22418 breaking out part of COMPOSITION_DECODE_RULE.
22419 (COMPOSITION_DECODE_RULE): Use it.
22420 * composite.c (get_composition_id): Remove unused local vars,
22421 by using the new macro.
22423 * textprop.c (set_text_properties_1): Change while to do-while,
22424 since the condition is always true at first.
22426 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22427 (interval_deletion_adjustment): Return unsigned value.
22430 * process.c (list_processes_1, create_pty, read_process_output):
22431 (exec_sentinel): Remove vars that were set but not used.
22432 (create_pty): Remove unnecessary "volatile"s.
22433 (Fnetwork_interface_info): Avoid possibility of int overflow.

22440 (update_syntax_table): Use unsigned instead of int.
22442 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22443 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22444 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22446 * print.c (print_error_message): Avoid int overflow.
22448 * font.c (font_list_entities): Redo for clarity,
22449 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22451 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22452 (font_score): Avoid potential overflow in diff calculation.
22454 * fns.c (substring_both): Remove var that is set but not used.
22455 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22457 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22459 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22460 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22461 can always succeed if overflow has undefined behavior.
22463 * search.c (boyer_moore, wordify): Remove vars set but not used.
22464 (wordify): Omit three unnecessary tests.
22466 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22467 All callers changed. This avoids the need for an unused var.
22469 * casefiddle.c (casify_region): Remove var that is set but not used.
22471 * dired.c (file_name_completion): Remove var that is set but not used.
22473 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22475 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22476 (Finsert_file_contents): Remove unnecessary code checking fd.
22478 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22479 Check for integer overflow on size calculations.
22481 * buffer.c (Fprevious_overlay_change): Remove var that is set
22484 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22485 Remove vars that are set but not used.
22486 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22487 (timer_check_2): Mark vars as initialized.
22489 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22491 * image.c (lookup_image): Remove var that is set but not used.
22492 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22494 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22495 that are set but not used.
22497 * xfns.c (make_invisible_cursor): Don't return garbage
22498 if XCreateBitmapFromData fails (Bug#8410).
22500 * xselect.c (x_get_local_selection, x_handle_property_notify):
22501 Remove vars that are set but not used.
22503 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

22513 (map_tty_color) [!defined MSDOS]: Likewise.
22515 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22517 * coding.c: Remove vars that are set but not used.
22518 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22519 All callers changed.
22520 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22521 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22522 (decode_coding_charset): Remove vars that are set but not used.
22524 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22525 that is set but not used.
22527 * print.c (print_object): Remove var that is set but not used.
22529 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22530 The gnulib version avoids calling malloc in the usual case,
22531 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22532 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22533 * filelock.c (current_lock_owner): Likewise.
22534 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22535 * sysdep.c: Include allocator.h, careadlinkat.h.
22536 (emacs_no_realloc_allocator): New static constant.
22537 (emacs_readlink): New function.
22538 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22539 ../lib/careadlinkat.h.
22541 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22543 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22544 first non-nil return value).
22546 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
22548 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22549 if not defined (Bug#8403).

22553 * xdisp.c (display_count_lines): Remove parameter `start',
22554 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

22558 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22559 and thereabouts. All callers changed.
22560 (get_per_char_metric): Remove parameter `f', unused since
22561 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22565 do not dereference NULL upon failed strdup
22566 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22567 (ns_get_family): Likewise.
22569 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22571 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.

22600 * image.c (parse_image_spec): Use Ffunctionp.
22602 * fns.c (concat, mapcar1): Accept byte-code-functions.
22604 * eval.c (Fsetq): Handle lexical vars.
22605 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22606 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22607 (FletX, Flet): Obey lexical binding.
22608 (Fcommandp): Handle closures.
22609 (Feval): New `lexical' arg.
22610 (eval_sub): New function extracted from Feval. Use it almost
22611 everywhere where Feval was used. Look up vars in lexical env.
22613 (Ffunctionp): Move from subr.el.
22614 (Ffuncall): Handle closures.
22615 (apply_lambda): Remove `eval_flags'.
22616 (funcall_lambda): Handle closures and new byte-code-functions.
22617 (Fspecial_variable_p): New function.
22618 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22619 but without exporting it to Lisp.
22621 * doc.c (Fdocumentation, store_function_docstring):
22622 * data.c (Finteractive_form): Handle closures.
22624 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22627 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22629 (exec_byte_code): New function extracted from Fbyte_code to handle new
22630 calling convention for byte-code-functions. Add new byte-codes.
22632 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22634 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22636 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22638 * xdisp.c (redisplay_internal): Fix prototype.
22640 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22642 * xdisp.c (SCROLL_LIMIT): New macro.
22643 (try_scrolling): Use it when setting scroll_limit.
22644 Limit scrolling to 100 screen lines.
22645 (redisplay_window): Even when falling back on "recentering",
22646 position point in the window according to scroll-conservatively,
22647 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22649 (try_scrolling): When point is above the window, allow searching
22650 as far as scroll_max, or one screenful, to compute vertical
22651 distance from PT to the scroll margin position. This prevents
22652 try_scrolling from unnecessarily failing when
22653 scroll-conservatively is set to a value slightly larger than the
22654 window height. Clean up the case of PT below the margin at bottom
22655 of window: scroll_max can no longer be INT_MAX. When aggressive
22656 scrolling is in use, don't let point enter the opposite scroll
22657 margin as result of the scroll.
22658 (syms_of_xdisp) <scroll-conservatively>: Document the
22659 threshold of 100 lines for never-recentering scrolling.
22661 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22663 * dispextern.h (move_it_by_lines):
22664 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22665 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22666 (message_log_check_duplicate): Remove parameters `prev_bol' and
22667 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22668 (redisplay_internal): Remove parameter `preserve_echo_area',
22669 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22671 * indent.c (Fvertical_motion):
22672 * window.c (window_scroll_pixel_based, Frecenter):
22673 Don't pass `need_y_p' to `move_it_by_lines'.
22675 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22677 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22678 steal a few bits to be more compact.
22679 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22680 Remove unneeded casts.
22682 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22684 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22686 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22687 binding" message (bug#7967).
22689 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22691 Fix more problems found by GCC 4.6.0's static checks.
22693 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22694 Remove unused local var.
22696 * editfns.c (Fmessage_box): Remove unused local var.
22698 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22699 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22700 Omit unused local vars.
22701 * window.c (shrink_windows): Omit unused local var.
22702 * menu.c (digest_single_submenu): Omit unused local var.
22703 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22704 Omit unused local var.
22706 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22707 Don't assume string length fits in int.
22708 (keyremap_step, read_key_sequence): Use size_t for sizes.
22709 (read_key_sequence): Don't check last_real_key_start redundantly.
22711 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22712 instead of alloca (Bug#8344).
22714 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22715 (Fbacktrace_frame): Don't assume nframes fits in int.
22717 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22719 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22722 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22724 * cm.c (calccost): Turn while-do into do-while, for clarity.
22726 * keyboard.c (syms_of_keyboard): Use the same style as later
22727 in this function when indexing through an array. This also
22728 works around GCC bug 48267.
22730 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22732 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22734 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22735 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22737 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22738 This avoids undefined behavior on integer overflow, and is a bit
22739 more convenient anyway since it is compared to a size_t variable.
22741 Variadic C functions now count arguments with size_t, not int.
22742 This avoids an unnecessary limitation on 64-bit machines, which
22743 caused (substring ...) to crash on large vectors (Bug#8344).
22744 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22745 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22746 All variadic functions and their callers changed accordingly.
22747 (struct gcpro.nvars): Now size_t, not int. All uses changed.
22748 * data.c (arith_driver, float_arith_driver): Likewise.
22749 * editfns.c (general_insert_function): Likewise.
22750 * eval.c (struct backtrace.nargs, interactive_p)
22751 (internal_condition_case_n, run_hook_with_args, apply_lambda)
22752 (funcall_lambda, mark_backtrace): Likewise.
22753 * fns.c (concat): Likewise.
22754 * frame.c (x_set_frame_parameters): Likewise.
22755 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22756 0 if not found, not -1. All callers changed.
22758 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22759 (stack_copy_size): Now size_t, not int.
22760 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22762 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22764 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22765 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22766 All callers changed.
22768 * lisp.h (multibyte_char_to_unibyte):
22769 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22770 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22771 * character.h (CHAR_TO_BYTE8):
22772 * cmds.c (internal_self_insert):
22773 * editfns.c (general_insert_function):
22774 * keymap.c (push_key_description):
22775 * search.c (Freplace_match):
22776 * xdisp.c (message_dolog, set_message_1): All callers changed.
22778 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
22780 * keyboard.c (safe_run_hook_funcall): New function.
22781 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22782 don't set the hook to nil, but remove the offending function instead.
22783 (Qcommand_hook_internal): Remove, unused.
22784 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22785 Vcommand_hook_internal.
22787 * eval.c (enum run_hooks_condition): Remove.
22788 (funcall_nil, funcall_not): New functions.
22789 (run_hook_with_args): Call each function through a `funcall' argument.
22790 Remove `cond' argument, now redundant.
22791 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
22792 (Frun_hook_with_args_until_failure): Adjust accordingly.
22793 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
22795 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22797 * dispextern.h (string_buffer_position): Remove declaration.
22799 * print.c (strout): Remove parameter `multibyte', unused since
22800 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
22802 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
22803 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22804 All callers changed.
22806 * w32.c (_wsa_errlist): Use braces for struct initializers.
22808 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
22809 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
22810 All callers changed.
22811 (string_buffer_position): Likewise. Also, make static (it's never
22812 used outside xdisp.c).
22813 (cursor_row_p): Remove parameter `w', unused since
22814 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

22816 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
22817 All callers changed.
22819 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22821 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
22823 2011-03-27 Anders Lindgren <andlind@gmail.com>
22825 * nsterm.m (ns_menu_bar_is_hidden): New variable.
22826 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
22827 (ns_update_auto_hide_menu_bar): New functions.
22828 (ns_update_begin): Call ns_update_auto_hide_menu_bar.
22829 (applicationDidBecomeActive): Call ns_update_auto_hide_menu_bar and
22830 ns_constrain_all_frames.
22831 (constrainFrameRect): Return at once if ns_menu_bar_should_be_hidden.
22832 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
22834 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22836 * nsmenu.m (runDialogAt): Remove argument to timer_check.
22838 2011-03-27 Glenn Morris <rgm@gnu.org>
22840 * syssignal.h: Replace RETSIGTYPE with void.
22841 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
22842 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
22843 Replace SIGTYPE with void everywhere.
22844 * s/usg5-4-common.h (SIGTYPE): Remove definition.
22845 * s/template.h (SIGTYPE): Remove commented out definition.
22847 2011-03-26 Eli Zaretskii <eliz@gnu.org>
22849 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
22850 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
22852 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
22854 * w32.c (read_unc_volume): Use parameter `henum', instead of
22855 global variable `wget_enum_handle'.
22857 * keymap.c (describe_vector): Remove parameters `indices' and
22858 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
22859 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
22861 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
22863 * keyboard.c (timer_check): Remove parameter `do_it_now',
22864 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
22865 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
22866 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
22868 * keyboard.c (read_char):
22869 * w32menu.c (w32_menu_display_help):
22870 * xmenu.c (show_help_event, menu_help_callback):
22871 Adjust calls to `show_help_echo'.
22873 * gtkutil.c (xg_maybe_add_timer):
22874 * keyboard.c (readable_events):
22875 * process.c (wait_reading_process_output):
22876 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
22878 * insdel.c (adjust_markers_gap_motion):
22879 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
22880 (gap_left, gap_right): Don't call it.
22882 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
22884 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
22885 incurred during fontification.

22926 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
22928 * w32term.c (x_set_glyph_string_clipping):
22929 Don't pass uninitialized region to CombineRgn.
22931 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
22933 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
22934 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
22935 (Fx_close_connection): Remove unused variable `i'.
22937 * w32font.c (w32font_draw): Return number of glyphs.
22938 (w32font_open_internal): Remove unused variable `i'.

22951 (uniscribe_font_driver): Add missing initializers.
22953 2011-03-23 Julien Danjou <julien@danjou.info>
22955 * term.c (Fsuspend_tty, Fresume_tty):
22956 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22957 * window.c (temp_output_buffer_show):
22958 * insdel.c (signal_before_change):
22959 * frame.c (Fhandle_switch_frame):
22960 * fileio.c (Fdo_auto_save):
22961 * emacs.c (Fkill_emacs):
22962 * editfns.c (save_excursion_restore):
22963 * cmds.c (internal_self_insert):
22964 * callint.c (Fcall_interactively):
22965 * buffer.c (Fkill_all_local_variables):
22966 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22968 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22969 unconditionally since it does the check itself.
22971 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22973 Fix more problems found by GCC 4.5.2's static checks.
22975 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22976 the first time through the loop, since we know p0 < p1 then.
22977 This also avoids a gcc -Wstrict-overflow warning.
22979 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22980 leading to a memory leak, possible in functions like
22981 load_charset_map_from_file that can allocate an unbounded number
22982 of objects (Bug#8318).
22984 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22985 that could (at least in theory) be that large.
22987 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22988 This is less likely to overflow, and avoids undefined behavior if
22989 overflow does occur. All callers changed. Use strtoul to scan
22990 for the unsigned long integer.
22991 (pint2hrstr): Simplify and tune code slightly.
22992 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22994 * scroll.c (do_scrolling): Work around GCC bug 48228.
22995 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22997 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22998 This also avoids a warning with gcc -Wstrict-overflow.
22999 (validate_x_resource_name): Simplify count usage.
23000 This also avoids a warning with gcc -Wstrict-overflow.
23002 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23005 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23007 * process.c (Fmake_network_process): Use socklen_t, not int,
23008 where POSIX says socklen_t is required in portable programs.
23009 This fixes a porting bug on hosts like 64-bit HP-UX, where
23010 socklen_t is wider than int (Bug#8277).
23011 (Fmake_network_process, server_accept_connection):
23012 (wait_reading_process_output, read_process_output):
23015 * process.c: Rename or move locals to avoid shadowing.
23016 (list_processes_1, Fmake_network_process):
23017 (read_process_output_error_handler, exec_sentinel_error_handler):
23018 Rename or move locals.
23019 (Fmake_network_process): Define label "retry_connect" only if needed.
23020 (Fnetwork_interface_info): Fix pointer signedness.
23021 (process_send_signal): Add cast to avoid pointer signedness problem.
23022 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
23023 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
23025 Make tparam.h and terminfo.c consistent.
23026 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23027 Include tparam.h instead, since it declares them.
23028 * cm.h (PC): Remove extern decl; tparam.h now does this.
23029 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23030 * terminfo.c: Include tparam.h, to check interfaces.
23031 (tparm): Make 1st arg a const pointer in decl. Put it at top level.

23087 clobbering (Bug#8298).
23088 * sysdep.c (sys_subshell): Likewise.
23089 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23091 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23092 This should get cleaned up, so that child_setup has the
23093 same signature on all platforms.
23095 * callproc.c (call_process_cleanup): Now static.
23096 (relocate_fd): Rename locals to avoid shadowing.

23227 some of which prompt warnings from gcc -Wbad-function-cast.
23228 (Fformat_time_string, Fencode_time, Finsert_char):

23257 (Fmemory_limit): Cast sbrk's returned value to char *.
23259 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

23265 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23266 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23267 to use the following functions instead of these macros.
23268 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23269 EMACS_INT, since callers assume the returned value fits in int.
23270 (upcase1): Likewise, for UPCASE_TABLE.
23271 (uppercasep, lowercasep, upcase): New static inline functions.
23272 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

23282 (regex_compile, re_match_2_internal): Mark locals as initialized.
23283 (RETALLOC_IF): Define only if needed.
23284 (WORDCHAR_P): Likewise. This one is never needed, but is used
23285 only in a comment talking about a compiler bug, so put inside
23286 the #if 0 of that comment.
23287 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23288 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

23314 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23315 New macros, so that the caller can use some names other than
23316 gcpro1, gcpro2, etc.
23317 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23319 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23320 argument, for consistency with GCPRO2_VAR, etc: it is now the
23321 prefix of the variable, not the variable itself. All uses
23323 * dired.c (directory_files_internal, file_name_completion):
23324 Rename locals to avoid shadowing.
23326 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23327 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23328 dired.c's scmp function, had undefined behavior.
23329 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23330 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23331 * buffer.h: ... to here, because these macros use current_buffer,
23332 and the new implementation with inline functions needs to have
23333 current_buffer in scope now, rather than later when the macros
23335 (downcase, upcase1): New static inline functions.
23336 (DOWNCASE, UPCASE1): Reimplement using these functions.
23337 This avoids undefined behavior in expressions like
23338 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23339 from race conditions in accessing the global variables
23340 case_temp1 and case_temp2.
23341 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23342 * lisp.h (case_temp1, case_temp2): Remove their decls.
23343 * character.h (ASCII_CHAR_P): Move from here ...
23344 * lisp.h: ... to here, so that the inline functions mentioned
23345 above can use them.
23347 * dired.c (directory_files_internal_unwind): Now static.
23349 * fileio.c (file_name_as_directory, directory_file_name):

23352 (file_name_as_directory): Use const pointers when appropriate.
23353 (Fexpand_file_name): Likewise. In particular, newdir might
23354 point at constant storage, so make it a const pointer.
23355 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23356 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23358 (Fset_file_times, Finsert_file_contents, auto_save_error):

23363 to avoid shadowing.
23365 * marker.c (bytepos_to_charpos): Remove; unused.
23367 * lisp.h (verify_bytepos, count_markers): New decls,
23368 so that gcc does not warn that these functions aren't declared.
23370 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23371 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23372 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23373 (copy_text): Remove unused local var.
23375 * filelock.c (within_one_second): Now static.
23376 (lock_file_1): Rename local to avoid shadowing.
23378 * buffer.c (fix_overlays_before): Mark locals as initialized.
23379 (fix_start_end_in_overlays): Likewise. This function should be
23380 simplified by using pointers-to-pointers, but that's a different
23382 (switch_to_buffer_1): Now static.
23383 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23384 (report_overlay_modification): Rename locals to avoid shadowing.

23387 Fix pointer signedness issue.
23388 (sys_subshell): Mark local as volatile if checking for lint,
23389 to suppress a gcc -Wclobbered warning that does not seem to be right.
23390 (MAXPATHLEN): Define only if needed.
23392 * process.c (serial_open, serial_configure): Move decls from here ...
23393 * systty.h: ... to here, so that they can be checked.
23395 * fns.c (get_random, seed_random): Move extern decls from here ...
23396 * lisp.h: ... to here, so that they can be checked.
23398 * sysdep.c (reset_io): Now static.
23399 (wait_for_termination_signal): Remove; unused.
23401 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

23404 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
23405 (DENSE_TABLE_SIZE): Remove; unused.
23406 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23407 (describe_map_tree):
23408 Rename locals to avoid shadowing.
23410 * keyboard.c: Declare functions static if they are not used elsewhere.
