9 2013-05-07 Paul Eggert <eggert@cs.ucla.edu>
11 Static checking by GCC 4.8.0.
12 * xfns.c (x_get_net_workarea, struct MonitorInfo, free_monitors)
13 (x_get_monitor_for_frame, x_make_monitor_attribute_list)
14 (x_get_monitor_attributes_fallback)
15 (x_get_monitor_attributes_xinerama)
16 (x_get_monitor_attributes_xrandr, x_get_monitor_attributes):
17 Define only if USE_GTK.
18 (free_monitors): Define only if HAVE_XINERAMA || HAVE_XRANDR.
19 (x_get_monitor_attributes_fallback): Omit unused locals.
20 (x_get_monitor_attributes_xinerama, Fx_display_monitor_attributes_list):

27 (XINERAMA_CFLAGS): New macros.
28 (ALL_CFLAGS, LIBES): Use them.
30 * xfns.c: Include <X11/extensions/Xrandr.h> if HAVE_XRANDR, and
31 include <X11/extensions/Xinerama.h> if HAVE_XINERAMA.
32 (Qgeometry, Qworkarea, Qmm_size, Qframes, Qsource): New variables.

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

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

129 Use parentheses to disambiguate last part of the condition.
131 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
132 assertion violations. (Bug#14062)
134 2013-05-01 David Reitter <david.reitter@gmail.com>
136 * nsfns.m (ns_tooltip): Initialize.
138 2013-04-28 Eli Zaretskii <eliz@gnu.org>
140 * coding.c (decode_coding_gap): Don't remove the character before
141 a newline unless it's a CR character. (Bug#14287)
143 2013-04-28 Dan Nicolaescu <dann@gnu.org>
145 * dispextern.h (struct face): Move enum face_underline_type

155 2013-04-27 Juri Linkov <juri@jurta.org>
157 * callint.c (Fcall_interactively): Call `Qread_number' for
158 interactive code letter `n' instead of using duplicate code.
161 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
163 * systime.h (make_timeval): Declare as 'const'.
165 2013-04-27 Kenichi Handa <handa@gnu.org>

170 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
172 Port better to AIX (Bug#14258).
173 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
176 2013-04-24 Kenichi Handa <handa@gnu.org>
178 * coding.c (decode_coding_iso_2022): When an invalid escape
179 sequence is encountered, reset the invocation and designation
180 status to the safest one.

184 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
185 Without this fix, "make distclean" leaves stamp-h1 behind.
187 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
189 * w32fns.c (w32_fullscreen_rect): New function to compute the
190 window rectangle for the given fullscreen mode.
191 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
192 longer tunes the window size. This keeps the window's edges flush
193 with the screen and allows the taskbar to hide itself in fullboth.
195 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
196 window decorations and uses the entire screen.
198 * w32term.h (w32_fullscreen_rect) Add prototype.
199 (struct w32_output): Replace normal_width, normal_height,
200 normal_top, and normal_left members with a single normal_placement
202 (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP):
204 (FRAME_NORMAL_PLACEMENT): New macro.
206 2013-04-16 Juanma Barranquero <lekktu@gmail.com>
208 * minibuf.c (Ftest_completion): Silence compiler warning.
210 2013-04-15 Eli Zaretskii <eliz@gnu.org>
212 * w32fns.c (w32_wnd_proc): Add more assertions to investigate
215 * frame.h (WINDOW_FRAME): Protect macro and its argument with
218 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
219 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
220 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
221 parentheses where appropriate.
223 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
225 * keyboard.c (timer_start_idle): Remove no-longer-used local.
227 2013-04-14 Eli Zaretskii <eliz@gnu.org>
229 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
230 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
231 Mention in the doc string that setting these variables takes
232 effect only after a call to set-window-buffer. (Bug#14200)
234 2013-04-13 Eli Zaretskii <eliz@gnu.org>
236 * indent.c (Fvertical_motion): Don't consider display strings on
237 overlay strings as display strings on the buffer position we
238 started from. This prevents vertical cursor motion from jumping
239 more than one line when there's an overlay string with a display
240 property at end of line.
241 Reported by Karl Chen <Karl.Chen@quarl.org> in
242 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.
244 2013-04-12 Stefan Monnier <monnier@iro.umontreal.ca>
246 * window.c (select_window): `record_buffer' even if window is
247 already selected (bug#14191).
249 2013-04-11 Eli Zaretskii <eliz@gnu.org>
251 * window.c (Fwindow_end): Test more flags, including the buffer's
252 last_overlay_modified flag, to determine whether the window's
253 display is really up-to-date. Prevents the function from
254 returning a stale value. (Bug#14170)
255 (Fwindow_line_height): Fix the test for up-to-date-ness of the
258 2013-04-10 Eli Zaretskii <eliz@gnu.org>
260 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
261 garbaged only if it is not already the top frame on its TTY.
262 This prevents flickering due to constant redrawing of TTY frames when
263 there are GUI frames open in the same session. (Bug#13864)
265 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
267 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
268 of marking the idle timers directly.
270 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
272 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
275 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>

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

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

347 changed. Check EOL format. Do not call adjust_coding_eol_type
349 (check_utf_8): New function.
350 (adjust_coding_eol_type): Do nothing if already adjusted.
351 (detect_coding): Compare the return value of check_ascii with
352 coding->src_bytes. Call adjust_coding_eol_type if necessary.
353 (decode_coding_gap): Optimize for valid UTF-8.
355 2013-03-21 Kenichi Handa <handa@gnu.org>
357 * coding.c (syms_of_coding): Cancel previous change.
359 * insdel.c (insert_from_gap): Fix previous change.
361 2013-04-05 Dmitry Antipov <dmantipov@yandex.ru>
363 Consistently use platform-specific function to detect window system.

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

412 * dispnew.c (sit_for): Don't mishandle NaNs.
413 This fixes a bug introduced in the 2013-03-24 change.
414 * editfns.c (decode_time_components): Don't hoist comparison.
415 This fixes another bug introduced in the 2013-03-24 change.

426 * nsmenu.m (showAtX:Y:for:): setLevel to
427 NSPopUpMenuWindowLevel (Bug#13998).
429 2013-03-30 Jan Djärv <jan.h.d@swipnet.se>
431 * nsterm.h (ns_get_pending_menu_title, ns_check_menu_open)

434 * nsmenu.m (ns_update_menubar): Correct NSTRACE.
435 (x_activate_menubar): Update the menu with title that matches

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

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

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

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

913 * w32term.c (w32_read_socket): If the Emacs frame is being
914 activated, call w32fullscreen_hook, to make sure the new frame
915 dimensions are in effect. (Bug#13937)
917 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
919 * xdisp.c (init_iterator): Simplify because both character and byte
920 positions are either specified or -1. Add eassert. Adjust comment.
921 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
922 character and byte positions can be obtained from marker.

942 Include <sys/param.h> unconditionally, as that works elsewhere and
943 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
944 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
947 2013-03-11 Paul Eggert <eggert@cs.ucla.edu>
949 * insdel.c (adjust_after_replace): Use bool for boolean.
951 2013-03-11 Stefan Monnier <monnier@iro.umontreal.ca>

1031 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
1032 from Elisp via unread-command-events.
1034 * keyboard.c (access_keymap_keyremap): Accept nil return value from
1035 functions to mean "no change".
1037 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>

1045 (search_regs_saved, Fregexp_quote):
1046 Use bool for boolean.
1047 * region-cache.c (region_cache_forward, region_cache_backward):
1048 Fix comments to match code: these functions return int, not boolean.
1050 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1052 * search.c (find_newline): Accept start and end byte positions
1053 as arguments and allow -1 if not known.

1088 to match other functions accepting character and byte positions.
1090 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

1092 when you need just to move to the previous buffer position.
1093 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1095 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1168 2013-03-06 Paul Eggert <eggert@cs.ucla.edu>
1170 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1171 * sysdep.c (list_system_processes)
1172 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1173 Make it a stub in this case; otherwise the build might fail,
1174 and this code hasn't been tested on such hosts anyway.
1175 Problem reported by Nelson H. F. Beebe in
1176 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1177 and analyzed by Jérémie Courrèges-Anglas in
1178 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00062.html>.
1180 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1182 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1183 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1184 (get_visually_first_element, move_it_vertically_backward): Ajust users.

1188 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1190 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1191 * filelock.c: Include <c-ctype.h>.
1192 (MAX_LFINFO): New top-level constant.
1193 (lock_info_type): Remove members pid, boot_time. Add members at,
1194 dot, colon. Change user member to be the entire buffer, not a
1195 pointer. This allows us to handle the case where a foreign
1196 pid or boot time exceeds the local range. All uses changed.
1197 (LINKS_MIGHT_NOT_WORK): New constant.
1198 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1199 (defined_WINDOWSNT): Remove.
1200 (MAKE_LOCK_NAME, file_in_lock_file_name):
1201 Always use .#FILE (not .#-FILE) for the file lock,
1202 even if it is a regular file.
1203 (rename_lock_file): New function.
1204 (create_lock_file): Use it.
1205 (create_lock_file, read_lock_data):
1206 Prefer a symbolic link for the lock file, falling back on a
1207 regular file if symlinks don't work. Do not try to create
1208 symlinks on MS-Windows, due to security hassles. Stick with
1209 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1210 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1211 host may be using a Windowsish file system, and cannot use
1212 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1213 doesn't work. Don't fail merely because of a symlink-contents
1214 length limit in the current file system; fall back on regular
1215 files. Increase the symlink contents length limit to 8 KiB, this
1216 should be big enough for any real use and doesn't crunch the
1218 (create_lock_file, lock_file_1, read_lock_data):
1219 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1220 (lock_file_1): Return error number, not bool. All callers changed.
1221 (ELOOP): New macro, if not already defined.
1222 (read_lock_data): Return size of lock file contents, not Lisp object.
1223 All callers changed. Handle a race condition if some other process
1224 replaces a regular-file lock with a symlink lock or vice versa,
1225 while we're trying to read the lock.
1226 (current_lock_owner): Parse contents more carefully, to help avoid
1227 confusing a regular-file lock with some other application's use
1228 of the file. Check for lock file contents being too long, or
1229 not parsing correctly.
1230 (current_lock_owner, lock_file):
1231 Allow foreign pid and boot times that exceed the local range.
1232 (current_lock_owner, lock_if_free, lock_file):
1233 Simplify allocation of lock file contents.
1234 * w32.c (sys_rename_replace): New function, containing most of
1235 the contents of the old sys_rename.
1236 (sys_rename): Use it.
1237 (fchmod): New dummy function.
1238 * w32.h (sys_rename_replace, fchmod): New decls.
1240 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1242 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1243 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1244 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1245 <dmantipov@yandex.ru>.
1247 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1249 * composite.c (get_composition_id, fill_gstring_header):
1250 Use make_uninit_vector where appropriate.
1251 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1252 * xselect.c (clean_local_selection_data): Likewise.
1254 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1256 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1257 * image.c (imagemagick_load_image): Calculate height and width
1258 after flattening the image, not before.
1260 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1262 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1263 * ftfont.c (ftfont_shape_by_flt): Likewise.
1264 * w32uniscribe.c (uniscribe_shape): Likewise.
1266 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1268 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1269 The old approach, which fell back on DIR/.#FILE.0 through
1270 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1271 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1272 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1273 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1274 because the locking mechanism was never reliable in that case).
1275 This patch fixes this and other bugs discovered by a code
1276 inspection that was prompted by
1277 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1278 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1279 to avoid interoperability problems between the MS-Windows and
1280 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1281 instances of Emacs now ignore each others' locks.
1282 * filelock.c (defined_WINDOWSNT): New constant.
1283 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1284 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1285 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1286 regular files on MS-Windows hosts.
1287 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1288 Use SAFE_ALLOCA to avoid problems with long file names.
1289 (MAX_LFINFO): Now a local constant, not a global macro.
1290 (IS_LOCK_FILE): Remove.
1291 (lock_file_1): Don't inspect errno if symlink call succeeds;
1292 that's not portable.
1293 (lock_file): Document that this function can return if lock
1295 (lock_file): Don't access freed storage.
1297 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

1301 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1303 * textprop.c: Use bool for booleans.
1304 (validate_interval_range, Fadd_text_properties)
1305 (Fremove_text_properties): Prefer bool to int when either works.
1307 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1309 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1310 If the interval tree changes as a side effect of calling
1311 modify_region, re-do processing starting from the call to
1312 validate_interval_range. (Bug#13743)
1314 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1316 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1319 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1321 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1322 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1323 access to the lock file until it is written and closed.
1326 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1328 * callint.c (Qcall_interactively):

1338 Minor textprop integer cleanup.
1339 * intervals.h, textprop.c (add_text_properties_from_list):
1340 Return void, not int, since nobody uses the return value.
1341 * textprop.c (validate_plist, add_properties, remove_properties)
1342 (Fadd_text_properties):
1343 Don't assume list length fits in int.

1350 (Fremove_list_of_text_properties):
1351 Reindent do-while as per GNU style.
1353 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1355 Implement CLASH_DETECTION for MS-Windows.
1357 * filelock.c [WINDOWSNT]: Include w32.h.
1358 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1359 function of that name. Up-case the macro arguments.
1360 (IS_LOCK_FILE): New macro.
1361 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1362 (create_lock_file): New function, with body extracted from
1364 [WINDOWSNT]: Implement lock files by writing a regular file with
1365 the lock information as its contents.
1366 (read_lock_data): New function, on Posix platforms just calls
1368 [WINDOWSNT]: Read the lock info from the file.
1369 (current_lock_owner): Call read_lock_data instead of calling
1370 emacs_readlinkat directly.
1371 (lock_file) [WINDOWSNT]: Run the file name through
1374 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1375 just check if the process by that PID exists.
1377 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1378 also present, as doing so will fail to error out if the file
1381 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1383 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1384 (Fremove_list_of_text_properties): Skip all of the intervals in
1385 the region between START and END that already have resp. don't
1386 have the requested properties, not just the first one.
1387 Add assertions that the loop afterwards always modifies the
1388 properties. (Bug#13743)
1390 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>
1392 * callint.c (Fcall_interactively): Use the right lexical environment

1418 * vm-limit.c: Move most of mem-limits.h's contents here.
1419 (data_start): New decl. It's OK if this is approximate,
1420 so simplify-away some unnecessary exactness.
1421 (POINTER): Remove; all uses removed.
1422 (data_space_start): Now char *, to avoid casts.
1423 (exceeds_lisp_ptr): New function, replacing the old
1424 EXCEEDS_LISP_PTR macro. All uses changed.

1446 * ralloc.c (SIZE, POINTER, NIL):
1447 * vm-limit.c (POINTER):
1448 Remove, replacing all uses with C89 equivalents. These old
1449 symbols were present only for porting to pre-C89 platforms.
1451 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1453 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.

1469 2013-02-19 Daniel Colascione <dancol@dancol.org>
1471 * sheap.c (report_sheap_usage): Use message, not message1, so
1472 that we don't try to create a buffer while we're in the middle
1473 of dumping Emacs. Explain why.
1475 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>

1524 unconditionally. (Bug#9066)
1526 * w32.c (set_errno): Reset h_errno and don't set it to any other
1527 value. Set errno instead.

1540 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1542 * keyboard.c (read_char): Fix calculation of auto-save time out
1543 when auto-save-timeout is less than 4. (Bug#13720)

1572 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1574 Fix AIX port (Bug#13650).
1575 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1576 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1577 was #undeffed earlier, so it cannot be used as a macro here.
1578 Use the constant and not the macro.
1580 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1582 * w32proc.c (new_child): If no vacant slots are found in
1583 child_procs[], make another pass looking for slots whose process
1584 has exited or died. (Bug#13546)
1586 * w32.c (sys_pipe): When failing due to file descriptors above
1587 MAXDESC, set errno to EMFILE.
1588 (_sys_read_ahead): Update cp->status when failing to read serial
1589 communications input, so that the status doesn't stay at
1590 STATUS_READ_IN_PROGRESS. (Bug#13546)
1592 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1594 * gtkutil.c (tb_size_cb): New function.

1604 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1606 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1614 2013-02-13 Glenn Morris <rgm@gnu.org>
1616 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1618 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1620 Improve AIX port some more (Bug#13650).
1621 With this, it should be as good as it was in 23.3, though it's
1622 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1623 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1624 * unexaix.c (start_of_text): Remove.
1625 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1626 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1627 (orig_load_scnptr, orig_data_scnptr):
1628 Now off_t, not long, since they are file offsets.
1629 (make_hdr): Use _data, not start_of_data ().
1630 This is the key part of the fix.
1631 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1632 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1634 * pre-crt0.c (data_start): Initialize to 1.
1635 This ports to compilers that optimize the external declaration
1636 'int x = 0;' as if it were 'int x;' to shrink the executable.
1638 Improve AIX port (Bug#13650).
1639 This doesn't fix the bug, but it makes progress: Emacs builds now.
1640 * unexaix.c: Include inttypes.h, stdarg.h.
1641 (report_error, report_error_1): Mark as _Noreturn.
1642 (report_error): Don't report the wrong errno.
1643 (report_error_1): Now varargs. All callers changed.
1644 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1645 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1646 (write_ptr): Use %p to print address rather than %lx and a cast
1647 to unsigned long. Grow buffer a bit, to be safer.
1649 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1651 * bidi.c (bidi_resolve_neutral): After finding the next
1652 non-neutral character, accept NEUTRAL_ON type as well, because
1653 directional control characters, such as LRE and RLE, have their
1654 type converted to that by bidi_resolve_weak. This avoids aborts
1655 when LRE/RLE follows a run of neutrals.
1656 (bidi_move_to_visually_next): Assert that return value of
1657 bidi_peek_at_next_level is non-negative. Negative values will
1660 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1662 Minor getenv-related fixes.
1663 * callproc.c (Fcall_process_region) [!DOS_NT]:
1664 Avoid unnecessary duplicate call to getenv.
1665 * callproc.c (init_callproc):
1666 * dispnew.c (init_display):
1667 * sysdep.c (sys_subshell):
1668 Omit unnecessary cast of getenv or egetenv.
1670 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1672 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1673 Update dependencies.
1675 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1677 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1679 (display_line): Set w->region_showing to the value of
1680 it->region_beg_charpos, not to -1. This fixes redisplay
1681 optimization when cursor is moved up after M->. (Bug#13623)
1683 (try_scrolling): Scroll text up more if point is too close to ZV
1684 and inside the scroll margin. This makes sure point is moved
1685 outside the scroll margin in these cases.
1687 * window.h (struct window): region_showing can no longer be
1690 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1692 Tune by using memchr and memrchr.
1693 * doc.c (Fsnarf_documentation):
1694 * fileio.c (Fsubstitute_in_file_name):
1695 * search.c (find_newline, scan_newline):
1696 * xdisp.c (pos_visible_p, display_count_lines):
1697 Use memchr and memrchr rather than scanning byte-by-byte.
1698 * search.c (find_newline): Rename from scan_buffer.
1699 Omit first arg TARGET, as it's always '\n'. All callers changed.
1701 Clean up read_key_sequence a tiny bit more.
1702 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1703 (read_key_sequence): Remove unused locals.
1705 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1707 Clean up read_key_sequence a bit; reread active keymaps after first event.
1708 * keyboard.c (read_char, read_char_x_menu_prompt)
1709 (read_char_minibuf_menu_prompt):
1710 Replace nmaps+maps with a single `map' arg.
1711 (follow_key): Operate on a single map.
1712 (active_maps): New function.
1713 (test_undefined): Also return true for nil bindings.
1714 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1715 a single (composed) keymap. Remember `first_event' to choose the right
1716 set of active keymaps. Recompute the set of keymaps after receiving
1717 the first event. Remove GOBBLE_FIRST_EVENT.
1718 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1719 * keyboard.h (read_char): Update declaration.
1720 * lread.c (read_filtered_event): Adjust call to read_char.
1722 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1724 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1725 Don't use the limitation on backwards movement when lines are truncated
1726 in the window. (Bug#13675)
1728 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1730 * marker.c (set_marker_internal): If desired position is passed
1731 as a marker, avoid call to buf_charpos_to_bytepos.
1732 * window.c (Fset_window_point): Omit redundant type checking.
1733 (Fset_window_start): Likewise. Format comment.
1734 (window_scroll_pixel_based): Use set_marker_restricted_both
1735 with character and byte positions obtained from an iterator.
1736 (Fset_window_configuration): Use set_marker_restricted_both.
1737 * xdisp.c (message_dolog): Likewise.
1739 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1741 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1742 When text lines are longer than window's screen lines, don't move back
1743 too far. This speeds up some redisplay operations. (Bug#13675)
1745 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1747 * syntax.c (scan_sexps_forward): Fix byte position calculation
1748 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1750 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1752 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1753 that was not needed.
1755 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1757 Minor hashing refactoring.
1758 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1759 (sxhash_float): Return EMACS_UINT, for consistency with the other
1761 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1762 non-static inline function and therefore can't use static vars.
1763 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1764 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1765 with the other hash functions.
1767 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1769 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1770 XXXXXX part of the temporary file pattern is not downcased even
1771 when w32-downcase-file-names is non-nil. (Bug#13661)
1773 * xdisp.c (decode_mode_spec): Remove handling of %t.

1859 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1861 * xdisp.c (window_buffer_changed): region_showing can be negative,

1863 (redisplay_internal): Resurrect code that forced redisplay of the
1864 whole window when showing region and the mark has changed.
1865 Record the new mark position to allow redisplay optimizations.
1866 (display_line): If it->region_beg_charpos is non-zero, set the
1867 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1869 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1870 not bitfield of 1 bit.
1872 2013-02-03 Daniel Colascione <dancol@dancol.org>
1874 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1875 daemon mode works on cygw32 when Emacs is installed and not just
1878 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1880 Avoid file time stamp bug on MS-Windows (Bug#13149).
1881 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1882 as FAT32 doesn't update time stamps when truncating them.
1883 Also, check that a file time stamp is not a multiple of 100 ns;
1884 this should catch all instances of the problem on MS-Windows,
1885 as its native file system resolution is 100 ns or worse, and
1886 checking for a non-multiple of 100 ns should impose only a small
1887 overhead on systems with ns resolution.
1889 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1891 Avoid encoding file names on MS-Windows when they need to be run
1892 through dostounix_filename.
1893 * w32.c (normalize_filename): Accept an additional argument
1894 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1895 downcase it even if w32-downcase-file-names is non-nil.
1896 (dostounix_filename): Accept an additional argument MULTIBYTE and
1897 pass it to normalize_filename.
1898 (emacs_root_dir): Adjust.
1900 * msdos.h (dostounix_filename): Adjust prototype.
1902 * w32.h (dostounix_filename): Adjust prototype.
1904 * msdos.c (dostounix_filename): Accept an additional argument and
1906 (init_environment): Adjust callers of dostounix_filename.
1908 * fileio.c (Ffile_name_directory, file_name_as_directory)
1909 (directory_file_name, Fexpand_file_name)
1910 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1912 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1914 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1915 variables, as egetenv is case-insensitive for DOS_NT.
1917 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1918 with an encoded file name.
1920 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1921 Adjust calls to dostounix_filename.
1923 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1925 * unexw32.c (unexec): Adjust call to dostounix_filename.
1927 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1929 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1932 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1935 * callproc.c (Fcall_process): Make sure program name in PATH and
1936 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1937 is passed to exec/spawnve, which fails unless the file-name
1940 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1941 even if w32-quote-process-args is nil.
1943 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1945 Fix timestamp bug when write-region appends nothing (Bug#13149).
1946 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1947 the file's time stamp doesn't change if Emacs happens to write nothing
1948 to the file, and on a buggy file system this could cause Emacs to
1949 incorrectly infer that the file system doesn't have the bug.
1950 Avoid this problem by inhibiting the inference in this case.
1952 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1954 * window.h (struct window): Convert base_line_number, base_line_pos
1955 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1956 Convert region_showing member from Lisp_Object to bitfield.
1957 Remove sequence_number member. Adjust comments.
1958 * window.c (sequence_number): Remove.
1959 (make_window): Initialize column_number_displayed.
1960 * print.c (print_object): Follow the printed representation of
1961 frames and print window pointer to distinguish between windows.
1962 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1963 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1964 (wset_column_number_displayed, wset_region_showing): Remove.
1965 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1966 (try_scrolling, try_cursor_movement, redisplay_window)
1967 (try_window_reusing_current_matrix, try_window_id, display_line)
1968 (display_mode_lines, decode_mode_spec): Adjust users.
1969 * .gdbinit (pwinx): Do not print sequence_number.
1971 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1973 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1974 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1975 * dired.c: Include <fcntl.h>.
1976 (open_directory): New function, which uses open and fdopendir
1977 rather than opendir. DOS_NT platforms still use opendir, though.
1978 (directory_files_internal, file_name_completion): Use it.
1979 (file_attributes): New function, with most of the old Ffile_attributes.
1980 (directory_files_internal, Ffile_attributes): Use it.
1981 (file_attributes, file_name_completion_stat): First arg is now fd,
1982 not dir name. All uses changed. Use fstatat rather than lstat +
1984 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1985 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1986 (emacs_readlinkat): New function, with much of the old
1987 Ffile_symlink_p, but with an fd argument for speed.
1988 It uses readlinkat rather than careadlinkatcwd, so that it
1989 need not assume the working directory.
1990 (Ffile_symlink_p): Use it.
1991 * filelock.c (current_lock_owner): Use emacs_readlinkat
1992 rather than emacs_readlink.
1993 * lisp.h (emacs_readlinkat): New decl.
1994 (READLINK_BUFSIZE, emacs_readlink): Remove.
1995 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1996 (emacs_norealloc_allocator, emacs_readlink): Remove.
1997 This stuff is moved to fileio.c.
1998 * w32.c (fstatat, readlinkat): New functions.
1999 (careadlinkat): Don't check that fd == AT_FDCWD.
2000 (careadlinkatcwd): Remove; no longer needed.
2002 2013-01-31 Glenn Morris <rgm@gnu.org>
2004 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
2005 (Fwrite_region): Update for new choose_write_coding_system args.
2006 Move the last piece of choose_write_coding_system here. (Bug#13522)
2007 (syms_of_fileio): Add choose-write-coding-system.
2009 2013-01-30 Eli Zaretskii <eliz@gnu.org>
2011 * w32.c (sys_open): Zero out the flags for the new file descriptor.
2012 (sys_close): Zero out the flags for the file descriptor before
2013 closing it. (Bug#13546)
2015 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
2016 (logon_network_drive, stat_worker, symlink, chase_symlinks):
2017 Use CharNextExA and CharPrevExA to iterate over file names encoded in
2020 * w32.c (w32_get_long_filename, init_environment, readlink):
2021 Support file names encoded in DBCS codepages.
2022 (readlink): Use the current file-name-coding-system, not the ANSI
2023 codepage, to decode and handle targets of symlinks.
2025 2013-01-28 Eli Zaretskii <eliz@gnu.org>
2027 * w32.c (opendir): Now accepts a 'const char *'.
2029 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
2031 Remove obsolete redisplay code. See the discussion at
2032 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
2033 * dispnew.c (preemption_period, preemption_next_check): Remove.
2034 (Vredisplay_preemption_period): Likewise.
2035 (update_frame, update_single_window, update_window, update_frame_1):
2036 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
2037 used, following the 2012-06-22 change.
2039 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2041 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
2043 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
2045 * font.c (num_fonts): Remove the leftover from old
2046 debugging code. Adjust comment style here and there.
2047 * insdel.c (insert_1): Remove.
2048 * lisp.h (insert_1): Remove prototype.
2049 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2051 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2053 * w32.c (max_filename_mbslen): New function.
2054 (normalize_filename, readdir): Use it to detect locales where ANSI
2055 encoding of file names uses a double-byte character set (DBCS).
2056 If a DBCS encoding is used, advance by characters using
2057 CharNextExA, instead of incrementing a 'char *' pointer.
2058 Use _mbslwr instead of _strlwr. (Bug#13515)
2060 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2061 request of memory reservation to 1.7GB. (Bug#13065)
2063 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2065 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2066 at check_extra_latin label. (Bug#13505)
2068 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2070 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2071 Avoid redundant calls to strlen.
2073 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2075 Drop async_visible and async_iconified fields of struct frame.
2076 This is possible because async input is gone; for details, see
2077 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2078 * frame.h (struct frame): Remove async_visible and async_iconified
2079 members, convert garbaged to unsigned bitfield. Adjust comments.
2080 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2081 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2082 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2083 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2084 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2086 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2087 properly. Likewise for obscured.
2089 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2092 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2094 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2096 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2097 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2099 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2101 * xdisp.c (message2, message2_nolog): Remove functions.
2102 (message3, message3_nolog): Extract nbytes and multibyteness directly
2103 from the string. Change all callers.
2104 (message3_nolog): Don't set message_enable_multibyte since set_message
2105 will reset it anyway.
2106 (message1, message1_nolog): Use message3.
2107 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2108 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2109 (set_message): Drop all but the second arg, which has to be a string.
2110 (set_message_1): Simplify now that we know that a1 is NULL and the
2111 second arg is a string.
2112 * frame.h (struct frame): Remove `message_buf' field.
2113 Use glyphs_initialized_p instead.
2114 (FRAME_MESSAGE_BUF): Remove macro.
2115 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2116 * lisp.h (message2, message2_nolog): Remove declarations.
2117 (message3, message3_nolog): Update declarations.
2118 * keyboard.c (read_char_minibuf_menu_text)
2119 (read_char_minibuf_menu_width): Remove vars.
2120 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2121 to correctly handle multibyte strings.
2122 * frame.c (delete_frame): Don't free message_buf any more.
2123 * editfns.c (message_text, message_length): Remove vars.
2124 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2125 * fileio.c (auto_save_error): Use message3 instead of message2.
2126 * dispnew.c (adjust_frame_message_buffer): Remove function.
2128 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2130 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2131 real estate used for the tool bar and the menu bar.
2133 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2135 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2136 hidden buffer is prepared to modification (Bug#13164).
2138 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2140 * window.h (struct window): Change window_end_valid member from
2141 Lisp_Object to a bitfield. Adjust comments.
2142 (wset_window_end_valid): Remove.
2143 * window.c (adjust_window_count): Clear window_end_valid.
2144 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2145 (Fwindow_line_height, set_window_buffer, Frecenter)
2146 (Fsplit_window_internal, Fdelete_other_windows_internal)
2147 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2148 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2149 * xdisp.c (check_window_end, reconsider_clip_changes)
2150 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2151 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2152 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2154 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2156 * xdisp.c (mark_window_display_accurate): Simplify the loop
2157 assuming that the only one of vchild, hchild or buffer window
2158 slots is non-nil. Call mark_window_display_accurate_1 for
2159 the leaf windows only.
2160 (mark_window_display_accurate_1): Always assume leaf window.
2163 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2165 * emacs.c (Qkill_emacs_hook): Now static.
2167 * fileio.c (Finsert_file_contents): Simplify.
2168 Remove unnecessary assignments and tests.
2170 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2172 * w32.c (acl_set_file): Don't test for errors unless
2173 set_file_security returns FALSE. Avoids spurious errors when
2176 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2178 * fileio.c (Finsert_file_contents): Revert code introduced at
2179 2013-01-18 in favor of the simpler and generally better fix.
2180 Save stack space by removing 'buffer' and reusing 'read_buf'
2183 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2185 * lisp.h (eabs): Define unconditionally (Bug#13419).
2186 The old "#if !defined (eabs)" was an unnecessary revenant of back
2187 when this macro was called "abs". Document 'eabs' better.
2189 2013-01-19 Glenn Morris <rgm@gnu.org>
2191 * fns.c (Frandom): Doc fix.
2193 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2195 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2196 segfault when there are lots of overlays.
2198 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2199 when there are lots of overlays.
2200 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2201 for the details and a way to reproduce.
2203 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2205 * fileio.c: Use O_APPEND to append.
2206 This corresponds better to the natural interpretation of "append",
2207 and avoids the need to open the output file twice, or to invoke
2208 lseek when APPEND is neither nil nor a number.
2209 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2210 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2211 file possibly twice, and lseeking to its end; this avoids the
2212 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2213 at the same time: the combination is never needed and apparently
2214 it doesn't work with DOS_NT.
2216 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2217 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2219 Allow floating-point file offsets.
2220 Problem reported by Vitalie Spinu in
2221 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2222 * fileio.c (emacs_lseek): Remove.
2223 (file_offset): New function.
2224 (Finsert_file_contents, Fwrite_region): Use it.
2226 2013-01-19 Chong Yidong <cyd@gnu.org>
2228 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2229 aborting on Fsignal (Bug#13289).
2231 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2233 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2234 set_file_security as failure due to insufficient privileges.
2235 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2236 (fstat): Return owner and group like 'stat' and 'lstat' do.
2238 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2240 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2241 The bug was observed on Ubuntu operating inside a virtual machine,
2242 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2243 The workaround introduces a race condition on non-buggy hosts,
2244 but it's an unlikely race and anyway there's a nearly identical
2245 nearby race that can't be fixed.
2246 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2248 (Fwrite_region): Test for file system time stamp bug.
2249 (init_fileio): New function.
2250 * lisp.h (init_fileio): Declare it.
2251 * emacs.c (main): Call it.
2253 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2254 and make it more consistent with other stat-failure diagnostics.
2256 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2258 Fix crash when inserting data from non-regular files.
2259 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2260 for the error description produced by valgrind.
2261 * fileio.c (read_non_regular): Rename to read_contents.
2262 Free Lisp_Save_Value object used to pass parameters.
2263 (read_non_regular_quit): Rename to read_contents_quit.
2264 (Finsert_file_contents): Redesign internal file reading loop to adjust
2265 gap and end positions after each read and so help make_gap to work
2266 properly. Do not signal an I/O error too early and so do not leave
2267 not yet decoded characters in a buffer, which was the reason of
2268 redisplay crash. Use list2 to build return value. Adjust comments.
2270 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2272 Close a race when statting and reading files (Bug#13149).
2273 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2274 This avoids a race if the file is renamed between stat and open.
2275 This race is not the problem originally noted in Bug#13149;
2276 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2278 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
2280 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
2281 objects, related functions and macros.
2282 (make_save_value): Adjust prototype.
2283 (make_save_pointer): New prototype.
2284 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
2285 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2286 * alloc.c (format_save_value): Rename to make_save_value.
2287 (make_save_pointer): New function.
2288 (record_xmalloc): Use make_save_pointer.
2289 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2290 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2291 Change users of make_save_value to make_save_pointer.
2292 Likewise for format_save_value and make_save_value.
2294 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
2296 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
2297 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.
2298 * buffer.c (toplevel, syms_of_buffer): Drop old commented-out
2301 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
2303 * alloc.c (free_save_value): Now static.
2305 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2307 * keymap.c (map_keymap_internal): Use format_save_value.
2308 (map_keymap_char_table_item): Adjust accordingly.
2309 * fileio.c (non_regular_fd, non_regular_inserted)
2310 (non_regular_nbytes): Remove.
2311 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2312 Use format_save_value to pass parameters to read_non_regular.

2376 Lisp_Save_Value and so avoid xmalloc.
2377 (save_excursion_restore): Adjust to match new layout. Use free_misc
2378 because we do not allocate extra memory any more. Add eassert.
2379 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2380 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.

2394 Fix SIGDANGER handlers, for AIX (Bug#13408).
2395 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:

2462 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
2464 * term.c (init_tty): Use them instead of rolling our own code.
2465 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2466 switches from 'signal' to 'pthread_sigmask', which is safer in
2467 multithreaded applications.
2468 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2469 which has already arranged for that.
2470 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2471 This is the main part of the bug fix.

2485 * buffer.c (buffer_slot_type_mismatch): Remove.
2486 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
2487 predicate. Adjust comment.

2490 left-margin-width, right-margin-width, left-fringe-width,
2491 right-fringe-width, scroll-bar-width and buffer-display-count.
2492 Use Qstringp for default-directory, buffer-file-name,
2493 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2494 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
2496 * data.c (store_symval_forwarding): Adjust to call the predicate.

2513 (make_gap_1): New function to adjust the gap of any buffer.
2514 * coding.c (coding_alloc_by_making_gap): Use it.
2515 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,

2539 trailing dash is properly added.
2541 2013-01-05 Eli Zaretskii <eliz@gnu.org>

2544 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2545 digits for buffer positions, before misalignment starts.
2546 Display "0" for integer "object" field.
2547 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2548 Display the newline glyph more unambiguously.
2550 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2552 * nsterm.m (ns_draw_underwave):
2553 * w32term.c (w32_draw_underwave):
2554 * xterm.c (x_draw_underwave): Make underwave look more triangular
2555 and also degrade gracefully for small fonts. (Bug#13000)
2557 * nsterm.m (ns_draw_text_decoration):
2558 * w32term.c (x_draw_glyph_string):
2559 * xterm.c (x_draw_glyph_string): Don't use previous underline
2560 thickness and position if previous underline type is underwave.
2562 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
2564 * fileio.c (Ffile_acl): Undocument return format.
2566 2013-01-02 Glenn Morris <rgm@gnu.org>
2568 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

2580 * term.c (tty_ins_del_lines):
2581 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2582 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2584 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2586 * w32.c (unsetenv): Set up the string passed to _putenv
2588 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2589 for the bug this caused.
2591 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2593 * coding.c (Qmac): Now static.
2595 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2597 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2598 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

2606 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2607 Check toolbar_is_packed.
2608 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2609 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2610 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2612 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2613 (xg_update_menubar): Update title only if
2614 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2615 (xg_update_submenu): Skip tearoff only if
2616 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2617 (xg_initialize): Initialize xg_detached_menus only if
2618 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2620 * xterm.h (struct x_output): Surround handlebox_widget with
2621 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2622 toolbar_in_hbox is bool.
2624 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2626 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2627 (LIBS_GNUSTEP): Define.
2628 (LIBES): Add $(LIBS_GNUSTEP).
2629 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
2631 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2633 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2634 continuation glyph on a TTY with an indication of an empty line.
2637 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2639 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2640 file's SELinux context or ACLs successfully set, nil otherwise.
2642 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.
2644 * w32proc.c (reader_thread): Avoid passing NULL handles to
2645 SetEvent and WaitForSingleObject.
2647 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2649 Port EXTERNALLY_VISIBLE to Clang 3.2.
2650 * conf_post.h (__has_attribute): New macro.
2651 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2653 2012-12-27 Glenn Morris <rgm@gnu.org>
2655 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2656 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2658 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2660 * fileio.c (file_name_as_directory, directory_file_name):
2661 Accept an additional argument MULTIBYTE to indicate whether the input C
2662 came from a multibyte or a unibyte Lisp string; all callers
2663 adjusted. Don't assume the input string is always multibyte.
2665 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2666 don't ENCODE_FILE them, and return a unibyte string if the input
2668 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2669 don't assume the input strings will always be multibyte. If the
2670 input strings are multibyte, decode strings obtained from C
2673 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2675 * lisp.h (toplevel): Add two notices to the comment about
2676 defining a new Lisp data type.

2680 * alloc.c (valid_lisp_object_p): Adjust comment.
2682 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2684 * keyboard.c (record_asynch_buffer_change): Initialize an event
2685 only if it's really needed.
2686 * frame.h (enum output_method): Remove output_mac member since
2687 it's a leftover from the deleted code.
2688 * frame.c (Fframep): Adjust user here ...
2689 * terminal.c (Fterminal_live_p): ... and here.
2690 * coding.c (Qmac): Now here because it's only used to denote
2691 end-of-line encoding type.
2692 (syms_of_coding): DEFSYM it.
2693 * frame.h (Qmac): Remove duplicated declaration.
2695 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2697 * window.c (select_window_1): Now static, since it's used only here.
2699 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2701 * window.c (window_body_cols): Subtract display margins from the
2702 window body width on TTYs as well. See
2703 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2704 for the original report.
2706 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2708 * xdisp.c (redisplay_window): Remove inner local variable
2709 because the outer shadowed one has the same meaning.
2710 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2712 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2713 (xg_create_tool_bar): Adjust users.
2715 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2717 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2718 * buffer.c (Fget_buffer_create): Use it to set compact field of
2719 struct buffer_text to avoid accessing an uninitialized value
2720 when compact_buffer is called for the first time.
2721 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2722 (Fset_buffer_modified_p): Use buffer_window_count to check
2723 whether the buffer is displayed in some window.
2724 * xdisp.c (message_dolog): Likewise.
2726 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2728 * w32.c (acl_set_file): If setting the file security descriptor
2729 fails, and the new DACL is identical to the existing one, silently
2730 return success. This fixes problems for users backing up their
2731 own files without having the necessary privileges for setting
2732 security descriptors.
2734 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2736 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2737 after WaitForSingleObject returns normally. This expedites reader
2738 thread shutdown when delete_child triggers it.
2739 (reap_subprocess): More accurate commentary for why we call
2740 delete_child only when cp->fd is negative.
2742 * w32.c (sys_close): Do not call delete_child on a subprocess
2743 whose handle is not yet closed. Instead, set its file descriptor
2744 to a negative value, so that reap_subprocess will call
2745 delete_child on that subprocess when its SIGCHLD arrives.
2746 This avoids closing handles used for communications between sys_select
2747 and reader_thread, which doesn't give sys_select a chance to
2748 notice that the process exited and invoke the SIGCHLD handler for
2751 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2753 * nsfns.m (Fns_do_applescript): Run event loop until script has
2754 been executed (Bug#12969).
2755 (ns_run_ascript): Chech as_script for nil, set to nil after
2758 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2760 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2762 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2764 * w32term.c (w32fullscreen_hook): New function.
2765 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2767 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2769 * fileio.c (Finsert_file_contents): Doc fix.
2771 * w32proc.c (new_child, delete_child, find_child_pid): For a
2772 subprocess, consider its slot being in use as long as its process
2773 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2774 slot when a new process is started immediately after killing
2775 another one, without waiting enough time for the first process to
2776 be reaped and resources allocated for it be orderly freed.
2778 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.

2791 Remove now unused argument FNAME; all callers changed.
2792 (get_file_owner_and_group): Remove now unused argument FNAME; all
2795 2012-12-21 Chong Yidong <cyd@gnu.org>
2797 * editfns.c (Finsert_char): Since read-char-by-name now signals an

2835 * coding.c (Fdetect_coding_region): Do not check start and end with
2836 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2837 (code_convert_region): Likewise.
2839 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2841 * w32.c (acl_get_file, acl_set_file): Run the file name through

2858 * window.c (select_window_1): New func, extracted from select_window.
2859 (select_window): Use it.

2886 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2888 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2889 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2890 for some of that bug's symptoms can now cause Emacs to abort.
2891 Remove the workaround.
2892 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2893 The bug that caused SIGCHLD to get lost has been fixed, and the
2894 workaround for it can now cause Emacs to abort.
2896 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2898 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2899 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in

2938 * callproc.c (Fcall_process): Don't overwrite infile with result
2940 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2941 asynchronous subprocess, record the name of the input file name,
2943 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2944 delete the file, record it as pending deletion when the subprocess
2947 2012-12-14 Eli Zaretskii <eliz@gnu.org>

2955 Fix permissions bugs with setgid directories etc. (Bug#13125)
2956 * dired.c (Ffile_attributes): Return t as the 9th attribute,

2967 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2969 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2970 try to get accurate owner and group information from NT file
2971 security APIs. This is to make most callers of 'stat' and
2972 'lstat', which don't need that information, much faster.
2974 * dired.c (Ffile_attributes) [WINDOWSNT]:
2975 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2976 owner and group information from 'lstat'.
2978 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2980 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2981 as that confuses set-auto-coding, so insist on the head-read

3007 files, fixing a regression from 24.2.
3008 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
3010 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
3012 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
3013 fstat shouldn't fail, and if it does fail copy-file should not proceed.
3014 Remove unnecessary S_ISLNK test, as (contra the comments) this
3015 function can't copy symlinks. Improve quality of error message
3016 when attempting to copy files that are neither regular files nor

3035 * inotify.c (inotify_callback): Generate an Emacs event for every
3036 incoming inotify event.
3038 2012-12-11 Eli Zaretskii <eliz@gnu.org>
3040 * xdisp.c (handle_face_prop): Fix logic of computing
3041 it->start_of_box_run_p.
3042 (append_space_for_newline): If the glyph row is R2L, reset the
3043 iterator's end_of_box_run_p flag before prepending the space glyph.
3044 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
3045 iterator's start_of_box_run_p flag before prepending the stretch.

3047 (append_stretch_glyph, append_glyphless_glyph): Reverse the
3048 left_box_line_p and right_box_line_p flags of the glyph for R2L
3049 glyph rows. (Bug#13011)

3261 (Fset_time_zone_rule): Do not save TZ and environ;
3262 no longer needed here.
3263 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
3264 Move to inside set_time_zone_rule; they don't need file scope any more.
3265 (set_time_zone_rule): Maintain the TZ=value string separately.
3266 (syms_of_editfns): Don't initialize initial_tz;
3267 init_editfns now does it.
3268 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
3269 * lisp.h (xputenv): New decl.
3271 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
3273 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
3275 2012-12-08 Eli Zaretskii <eliz@gnu.org>
3277 * w32.c (unsetenv, sys_putenv): New functions.
3279 2012-12-08 Chong Yidong <cyd@gnu.org>
3281 * editfns.c (Finsert_char): Make the error message more
3282 informative (Bug#12992).
3284 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
3286 Simplify get_lim_data.
3287 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
3288 Remove USG and vlimit methods; no longer used these days.
3289 Add #error catchall just in case.
3291 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
3292 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
3293 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
3294 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
3295 (deleted_pid_list, Fdelete_process, create_process)
3296 (record_child_status_change, handle_child_signal, deliver_child_signal)
3297 (init_process_emacs, syms_of_process):
3298 Assume SIGCHLD is defined.
3299 (parse_signal): Remove. All uses removed.
3300 (abbr_to_signal): New static function.
3301 (Fsignal_process): Use it to convert signal names to ints.
3302 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
3303 kill (getpgrp (), ...).
3304 (emacs_sigaction_init): Assume SIGCHLD is defined.
3305 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
3306 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
3307 * syssignal.h (EMACS_KILLPG): Remove.
3308 All uses replaced by 'kill' with a negative pid.
3309 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
3310 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
3312 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3314 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3315 This will cause a production Emacs to dump core instead of
3318 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3320 * frame.c (make_frame): Do not set window's buffer to t.
3321 * window.c (Fsplit_window_internal): Likewise. Previously it was
3322 used to indicate that the window is being set up. Now we use
3323 set_window_buffer for all new windows, so the condition in ...
3324 (Fset_window_buffer): ... is always true and can be removed.
3326 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3328 Convenient macro to check whether the buffer is hidden.
3329 * buffer.h (BUFFER_HIDDEN_P): New macro.
3330 * frame.c (make_frame): Use it. Adjust comment.
3331 * buffer.c (candidate_buffer): New function.
3332 (Fother_buffer, other_buffer_safely): Use it.
3334 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3336 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3337 if the child process is still running. Instead, exit the wait
3338 loop and return zero. (Bug#13086)
3340 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3342 * frame.h (x_char_width, x_char_height): Remove prototypes.
3343 * w32term.h (x_char_width, x_char_height): Likewise.
3344 * xfns.c (x_char_width, x_char_height): Remove.
3345 * w32fns.c (x_char_width, x_char_height): Likewise.
3346 * nsfns.c (x_char_width, x_char_height): Likewise.
3347 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for

3353 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
3355 Fix a recently-introduced delete-process race condition.
3356 * callproc.c, process.h (record_kill_process):
3357 New function, containing part of the old call_process_kill.
3358 (call_process_kill): Use it.
3359 This does not change call_process_kill's behavior.
3360 * process.c (Fdelete_process): Use record_kill_process to fix a
3361 race condition that could cause Emacs to lose track of a child.
3363 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3365 Avoid code duplication between prev_frame and next_frame.
3366 * frame.c (candidate_frame): New function. Add comment.
3367 (prev_frame, next_frame): Use it. Adjust comment.
3369 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3371 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3372 fails, signal an error instead of continuing with an empty
3374 Encode expanded temp file pattern before passing it to mkstemp or
3377 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3378 Encode the file name before passing it to dostounix_filename, in
3379 case it will downcase it (under w32-downcase-file-names).
3382 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3384 Minor call-process cleanups.
3385 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3386 at the same time as other platforms, to simplify analysis.
3387 No need for fd0_volatile since we have synch_process_fd.
3388 Avoid needless emacs_close; arg is always negative.
3390 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3392 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3395 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3397 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3398 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3399 and mouse_face_hidden members to a bitfields.
3400 * frame.h (struct frame): Remove set-but-not-used space_width member.
3401 (FRAME_SPACE_WIDTH): Remove.
3402 * nsterm.m, w32term.c, xterm.c: Adjust users.
3403 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3404 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3405 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3406 members to a bitfields.
3408 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3410 Don't let call-process be a zombie factory (Bug#12980).
3411 Fixing this bug required some cleanup of the signal-handling code.
3412 As a side effect, this change also fixes a longstanding rare race
3413 condition whereby Emacs could mistakenly kill unrelated processes,
3414 and it fixes a bug where a second C-g does not kill a recalcitrant
3415 synchronous process in GNU/Linux and similar platforms.
3416 The patch should also fix the last vestiges of Bug#9488,
3417 a bug which has mostly been fixed on the trunk by other changes.
3418 * callproc.c, process.h (synch_process_alive, synch_process_death)
3419 (synch_process_termsig, sync_process_retcode):
3420 Remove. All uses removed, to simplify analysis and so that
3421 less consing is done inside critical sections.
3422 * callproc.c (call_process_exited): Remove. All uses replaced
3423 with !synch_process_pid.
3424 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3425 These take the role of what used to be in unwind-protect arg.
3427 (block_child_signal, unblock_child_signal):
3428 New functions, to avoid races that could kill innocent-victim processes.
3429 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3430 (call_process_kill): Record killed processes as deleted, so that
3431 zombies do not clutter up the system. Do this inside a critical
3432 section, to avoid a race that would allow the clutter.
3433 (call_process_cleanup): Fix code so that the second C-g works again
3434 on common platforms such as GNU/Linux.
3435 (Fcall_process): Create the child process in a critical section,
3436 to fix a race condition. If creating an asynchronous process,
3437 record it as deleted so that zombies do not clutter up the system.
3438 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3439 light of these changes. Omit unnecessary call to emacs_close
3440 before failure, as the unwind-protect code does that.
3441 * callproc.c (call_process_cleanup):
3442 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3443 * process.c (record_deleted_pid): New function, containing
3444 code refactored out of Fdelete_process.
3445 (Fdelete_process): Use it.
3446 (process_status_retrieved): Remove. All callers changed to use
3447 child_status_change.
3448 (record_child_status_change): Remove, folding its contents into ...
3449 (handle_child_signal): ... this signal handler. Now, this
3450 function is purely a handler for SIGCHLD, and is not called after
3451 a synchronous waitpid returns; the synchronous code is moved to
3452 wait_for_termination. There is no need to worry about reaping
3453 more than one child now.
3454 * sysdep.c (get_child_status, child_status_changed): New functions.
3455 (wait_for_termination): Now takes int * status and bool
3456 interruptible arguments, too. Do not record child status change;
3457 that's now the caller's responsibility. All callers changed.
3458 Reimplement in terms of get_child_status.
3459 (wait_for_termination_1, interruptible_wait_for_termination):
3460 Remove. All callers changed to use wait_for_termination.
3461 * syswait.h: Include <stdbool.h>, for bool.
3462 (record_child_status_change, interruptible_wait_for_termination):
3464 (record_deleted_pid, child_status_changed): New decls.
3465 (wait_for_termination): Adjust to API changes noted above.
3467 * bytecode.c, lisp.h (Qbytecode): Remove.
3468 No longer needed after 2012-11-20 interactive-p changes.
3470 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3472 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3473 the scroll margin, move point outside the margin. (Bug#13055)
3475 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3477 * gtkutil.c (my_log_handler): New function.
3478 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3480 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3482 * lisp.h (modify_region): Rename to...
3483 (modify_region_1): ...new prototype.
3484 * textprop.c (modify_region): Now static. Adjust users.
3485 * insdel.c (modify_region): Rename to...
3486 (modify_region_1): ...new function to work with current buffer.
3487 Adjust comment and users. Use true and false for booleans.
3489 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3491 * alloc.c (free_save_value): New function.
3492 (safe_alloca_unwind): Use it.
3493 * lisp.h (free_save_value): New prototype.
3494 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3496 (save_excursion_restore): Adjust to match saved data structure.
3497 Use free_save_value to offload some work from GC. Drop obsolete
3500 2012-12-03 Chong Yidong <cyd@gnu.org>
3502 * fileio.c (Vauto_save_list_file_name): Doc fix.
3504 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3506 * w32fns.c: Remove prototype of atof.
3507 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3509 (file_dialog_callback): Make it UINT_PTR.
3511 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3514 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3515 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3518 2012-12-03 Glenn Morris <rgm@gnu.org>
3520 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3522 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3524 Fix xpalloc confusion after memory is exhausted.
3525 * alloc.c (xpalloc): Comment fix.
3526 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3527 and signals an error, do not clear charset_table_size, as
3528 charset_table is still valid.
3529 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3531 Use execve to avoid need to munge environ (Bug#13054).
3532 * callproc.c (Fcall_process):
3533 * process.c (create_process):
3534 Don't save and restore environ; no longer needed.
3535 * callproc.c (child_setup):
3536 Use execve, not execvp, to preserve environ.
3538 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3540 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3542 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3544 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3545 display for sliced images (Bug#10500).
3547 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3549 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3551 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3552 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3554 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3556 * xdisp.c (window_outdated): Remove eassert since it hits
3557 some suspicious corner cases (see Bug#13007 and Bug#13012).
3558 (mode_line_update_needed): New function.
3559 (redisplay_internal, redisplay_window): Use it.
3560 (ensure_selected_frame): New function.
3561 (redisplay_internal, unwind_redisplay): Use it.
3562 (redisplay_internal): Move comment about buffer_shared...
3563 (buffer_shared_and_changed): ...near to its real use.
3565 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3567 * callproc.c (Fcall_process): Don't misreport vfork failure.
3569 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3571 * callproc.c (Fcall_process): Fix vfork portability problems.
3572 Do not assume that fd[0], count, filefd, and save_environ survive
3573 vfork. Fix bug whereby wrong errno value could be reported for
3574 pipe failure. Some minor cleanups, too, as follows. Move buf and
3575 bufsize to the context where they're needed. Change new_argv to
3576 be of type char **, as this is more convenient and avoids casts.
3577 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3578 Now local constants, not macros.
3580 2012-11-18 Kenichi Handa <handa@gnu.org>
3582 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3583 for the variable "f".
3585 2012-11-13 Kenichi Handa <handa@gnu.org>
3587 * font.c (font_unparse_xlfd): Exclude special characters from the
3588 generating XLFD name.
3590 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3592 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

3603 * lread.c (readbyte_from_file): Assume EINTR is defined.
3604 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3605 Assume EIO and EAGAIN are defined.
3606 * unexcoff.c (write_segment): Assume EFAULT is defined.
3608 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3610 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3613 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3614 highlighting on the frame was cleared. Prevents assertion
3615 violations when repeatedly clicking on the "Top" link of the
3616 "bread-crumbs" in Info buffers.
3618 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

3625 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3626 were always defined.
3628 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3630 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3631 between bpos_covered and bpos_max. This fixes cursor display when
3632 several display strings follow each other.
3634 * .gdbinit (pgx): If the glyph's object is a string, display the
3635 pointer to string data, rather than the value of the string object
3636 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3638 * indent.c (Fvertical_motion): If the starting position is covered
3639 by a display string, return to one position before that, to avoid
3640 overshooting it inside move_it_to. (Bug#12930)
3642 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3644 * frame.h (struct frame): Remove display_preempted member

3647 * w32menu.c (pending_menu_activation): Remove since not
3649 (set_frame_menubar): Adjust user.
3650 * w32term.h (struct x_output): Drop outdated #if 0 code.
3651 (struct w32_output): Use bitfields for explicit_parent,
3652 asked_for_visible and menubar_active members.
3653 Drop unused pending_menu_activation member.
3654 * xterm.h (struct x_output): Drop outdated #if 0 code.
3655 Use bitfields for explicit_parent, asked_for_visible,
3656 has_been_visible and net_wm_state_hidden_seen members.
3658 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3660 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3661 of a literal "/". (Bug#12955)
3662 (gl-stamp): Invoke fc.exe directly, not through cmd.
3664 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>

3667 * dired.c: Assume HAVE_DIRENT_H.
3668 (NAMLEN): Remove, replacing with ...
3669 (dirent_namelen): New function. All uses changed. Use the GNU macro
3670 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3671 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3672 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3673 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3675 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3676 * ndir.h: Rename to ../nt/inc/dirent.h.
3677 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3678 Do not include <dirent.h>; no longer needed.
3679 * w32.c: Include <dirent.h> rather than "ndir.h".
3681 2012-11-23 Chong Yidong <cyd@gnu.org>
3683 * xftfont.c (xftfont_open): Remove duplicate assignment.
3685 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3687 * alloc.c (Fgarbage_collect): Unblock input after clearing
3688 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3689 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3690 * msdos.c (IT_frame_up_to_date): Use it here...
3691 * w32term.c (w32_frame_up_to_date): ...here...
3692 * xterm.c (XTframe_up_to_date): ...and here...
3693 * nsterm.m (ns_frame_up_to_date): ...but not here.
3694 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3696 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3697 Do not check whether GC is in progress.
3699 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3701 * xdisp.c (window_buffer_changed): New function.
3702 (update_menu_bar, update_tool_bar): Use it to
3703 simplify large 'if' statements.
3704 (redisplay_internal): Generalize commonly used
3705 'tail' and 'frame' local variables.
3707 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3709 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3710 with Windows system header.
3712 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3714 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3715 * alloc.c: Assume unistd.h exists.
3716 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3717 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3718 (getwd) [USG]: Remove; no longer needed.
3719 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3720 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3721 * w32.h (getcwd): Remove decl.
3723 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3725 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3726 Make it set selected_window as well.
3727 (update_tool_bar): Use it.
3729 2012-11-21 Ken Brown <kbrown@cornell.edu>
3731 * emacs.c (main): Set the G_SLICE environment variable for all
3732 Cygwin builds, not just GTK builds. See
3733 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3735 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3737 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3738 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3739 Define for the MSVC compiler.
3741 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3743 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3744 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3745 dostounix_filename. Prevents crashes down the road, because
3746 dostounix_filename assumes it gets a unibyte string.
3747 Reported by Michel de Ruiter <michel@sentient.nl>, see
3748 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3750 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3752 Conflate Qnil and Qunbound for `symbol-function'.

3754 * lread.c (init_obarray): Set `function' fields to Qnil.
3755 * eval.c (Fcommandp): Ignore Qunbound.
3756 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3757 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3758 Test NILP rather than Qunbound.
3759 (Ffmakunbound): Set to Qnil.
3760 (Fsymbol_function): Never signal an error.
3761 (Finteractive_form): Ignore Qunbound.
3763 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3765 * eval.c (interactive_p): Remove no-longer-used decl.
3767 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3769 * xdisp.c (buffer_shared): Adjust comment.
3770 (buffer_shared_and_changed): New function.
3771 (prepare_menu_bars, redisplay_internal): Use it to
3772 decide whether all windows or frames should be updated.
3773 (window_outdated): New function.
3774 (text_outside_line_unchanged_p, redisplay_window): Use it.
3775 (redisplay_internal): Likewise. Fix indentation.
3777 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3779 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3780 (syms_of_eval): Remove corresponding defsubr.
3781 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3783 2012-11-19 Daniel Colascione <dancol@dancol.org>
3785 * w32fns.c (Fx_file_dialog):
3786 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3787 cygwin_convert_file_name*.
3789 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3790 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3792 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3794 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3796 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3798 * w32select.c: Include w32common.h before w32term.h, so that
3799 windows.h gets included before w32term.h uses some of its
3800 features, see below.
3802 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3804 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3806 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3808 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3810 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3811 (ns_select): Return at once if events are held (Bug#12834).
3813 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3815 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3816 Needed following 2012-10-20 change. (Bug#12902)
3818 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3820 * w32proc.c (waitpid): Remove unused label get_result.
3822 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3824 * makefile.w32-in (SYSWAIT_H): New macro.
3825 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3826 ($(BLD)/sysdep.$(O)): Update dependencies.
3828 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3830 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3831 * callproc.c (relocate_fd): Assume F_DUPFD.
3832 * emacs.c, term.c (O_RDWR): Remove.
3833 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3834 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3835 * nsterm.m: Assume <fcntl.h> exists.
3836 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3837 (create_pty, Fmake_network_process, server_accept_connection)
3838 (wait_reading_process_output, init_process_emacs):
3840 (wait_reading_process_output): Put in a special case for WINDOWSNT
3841 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3842 It's not clear this is needed, but it's a more-conservative change.
3843 (create_process): Assume FD_CLOEXEC.
3844 (create_process, create_pty): Assume O_NOCTTY.
3845 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3846 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3847 Omit if not DOS_NT, since F_GETFL is not defined there.
3848 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3849 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3851 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3852 lack it, since gnulib guarantees this.
3853 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3855 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3857 * w32.c (faccessat): Pretend that directories have the execute bit
3858 set. Emacs expects that, e.g., in files.el:cd-absolute.
3860 * w32proc.c (create_child): Don't clip the PID of the child
3861 process to fit into an Emacs integer, as this is no longer a
3863 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3864 reaping only the process specified by PID argument, if that is
3865 positive. Use PID instead of dead_child to know which process to
3866 reap. Wait for the child to die only if WNOHANG is not in
3868 (sys_select): Don't set dead_child.
3870 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3871 as it is no longer needed.
3873 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3875 (record_child_status_change): Remove the setting of
3876 record_at_most_one_child for the !WNOHANG case.
3878 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3880 Fix problems in ns port found by static checking.
3881 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3882 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3883 not to process group.
3884 (ns_select): Use emacs_write, not write, as that's more robust
3885 in the presence of signals.
3886 (fd_handler:): Check for read errors.
3888 2012-11-16 Glenn Morris <rgm@gnu.org>
3890 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3892 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3894 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3896 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3898 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3899 use the same value of thread handle.
3900 (start_timer_thread): If the timer thread exited (due to error),
3901 clean up by closing the two handles it used. Duplicate the caller
3902 thread's handle here, so it gets duplicated only once, when
3903 launching the timer thread. Set priority of the timer thread, not
3905 (getitimer): Don't duplicate the caller thread's handle here.
3908 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3910 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3913 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3915 Remove no-longer-used pty_max_bytes variable.
3916 * process.c (pty_max_bytes): Remove; unused.
3917 (send_process): Do not set it.
3919 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3921 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3922 Update dependencies.
3924 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3926 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3927 This follows up on the 2012-09-29 patch that removed indirection
3928 for the 'function' field. Reported by Sergey Vinokurov in
3929 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3931 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3933 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3934 different name, as the MS runtime does not have such a function,
3935 and probably never will.) All callers changed. Ignore DIRFD
3936 value if PATH is an absolute file name, to match Posix spec
3937 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3940 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3942 * xdisp.c (echo_area_display, redisplay_internal):
3943 Omit redundant check whether frame_garbaged is set.
3945 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3947 Use faccessat, not access, when checking file permissions (Bug#12632).
3948 This fixes a bug that has been present in Emacs since its creation.
3949 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3950 which must set some sort of record. (Torek's bug report was against
3951 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3952 same common flaw.) See Torek's Usenet posting
3953 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3954 Posted: Fri Apr 8 14:18:56 1983.
3955 * Makefile.in (LIB_EACCESS): New macro.
3957 * callproc.c (init_callproc):
3958 * charset.c (init_charset):
3959 * fileio.c (check_existing, check_executable, check_writable)
3961 * lread.c (openp, load_path_check):
3962 * process.c (allocate_pty):
3964 Use effective UID when checking permissions, not real UID.
3965 * callproc.c (init_callproc):
3966 * charset.c (init_charset):
3967 * lread.c (load_path_check, init_lread):
3968 Test whether directories are accessible, not merely whether they exist.
3969 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3970 * fileio.c (check_existing, check_executable, check_writable)
3972 Use symbolic names instead of integers for the flags, as they're
3974 (check_writable): New arg AMODE. All uses changed.
3975 Set errno on failure.
3976 (Ffile_readable_p): Use faccessat, not stat + open + close.
3977 (Ffile_writable_p): No need to call check_existing + check_writable.
3978 Just call check_writable and then look at errno. This saves a syscall.
3979 dir should never be nil; replace an unnecessary runtime check
3980 with an eassert. When checking the parent directory of a nonexistent
3981 file, check that the directory is searchable as well as writable, as
3982 we can't create files in unsearchable directories.
3983 (file_directory_p): New function, which uses 'stat' on most platforms
3984 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3985 (Ffile_directory_p, Fset_file_times): Use it.
3986 (file_accessible_directory_p): New function, which uses a single
3987 syscall for efficiency.
3988 (Ffile_accessible_directory_p): Use it.
3989 * xrdb.c (file_p): Use file_directory_p.
3990 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3991 * lread.c (openp): When opening a file, use fstat rather than
3992 stat, as that avoids a permissions race. When not opening a file,
3993 use file_directory_p rather than stat.
3994 (dir_warning): First arg is now a usage string, not a format.
3995 Use errno. All uses changed.
3996 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3997 that merely introduced a race.
3998 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3999 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
4000 and similarly for the other O_* flags.
4001 * w32.c (sys_faccessat): Rename from sys_access and switch to
4002 faccessat's API. All uses changed.
4003 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
4004 (magic_db): Rename from magic_file_p.
4005 (magic_db, search_magic_path): Return an XrmDatabase rather than a
4006 char *, so that we don't have to test for file existence
4007 separately from opening the file for reading. This removes a race
4008 fixes a permission-checking problem, and simplifies the code.
4010 (file_p): Remove; no longer needed.
4012 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
4014 Omit glyphs initialization at startup.
4015 * dispnew.c (glyphs_initialized_initially_p): Remove.
4016 (adjust_frame_glyphs_initially): Likewise. Adjust users.
4017 (Fredraw_frame): Move actual code from here...
4018 (redraw_frame): ...to here. Add eassert. Adjust comment.
4019 (Fredraw_display): Use redraw_frame.
4020 * xdisp.c (clear_garbaged_frames): Likewise.
4022 2012-11-13 Eli Zaretskii <eliz@gnu.org>
4024 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
4025 passed to pint2str and pint2hrstr to be at most the size of the
4026 frame's decode_mode_spec_buffer. This avoids crashes with very
4027 large values of FIELD_WIDTH argument to decode_mode_spec.
4030 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
4032 Fix a race with verify-visited-file-modtime (Bug#12863).
4033 Since at least 1991 Emacs has ignored an mtime difference of no
4034 more than one second, but my guess is that this was to work around
4035 file system bugs that were fixed long ago. Since the race is
4036 causing problems now, let's remove that code.
4037 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
4038 whose time stamp is off by no more than a second. Insist that the
4039 file time stamps match exactly.
4041 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4043 * frame.h (struct frame): Convert external_tool_bar member to
4044 1-bit unsigned bitfield.
4045 * termhooks.h (struct terminal): Remove mouse_moved member since
4046 all users are long dead. Adjust comment on mouse_position_hook.
4048 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4050 Simplify by using FOR_EACH_FRAME here and there.
4051 * frame.c (next_frame, prev_frame, other_visible_frames)
4052 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4053 * w32term.c (x_window_to_scroll_bar): Likewise.
4054 * window.c (window_list): Likewise.
4055 * xdisp.c (x_consider_frame_title): Likewise.
4056 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4057 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4058 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4059 * xmenu.c (menubar_id_to_frame): Likewise.
4060 * xselect.c (frame_for_x_selection): Likewise.
4061 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4062 (x_window_to_menu_bar): Likewise.
4063 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4065 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4067 * data.c (Qdefalias_fset_function): Now static.
4069 Another tweak to vectorlike_header change.
4070 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4071 Remove, and replace all uses with ...
4072 (next_in_free_list, set_next_in_free_list):
4073 New functions, which respect C's aliasing rules better.
4075 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4077 * window.c (list4i): Rename from 'quad'. All uses changed.
4078 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4080 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4082 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4083 warning about mixing declarations and code in ISO C90.
4085 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4087 * window.c (Fsplit_window_internal): Set combination limit of
4088 new parent window to t iff Vwindow_combination_limit is t;
4089 fixing a regression introduced with the change from 2012-09-22.
4090 (Fset_window_combination_limit): Fix doc-string.
4092 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4094 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4095 amount when the scroll margins are too large. When scrolling
4096 backwards in the buffer, give up if cannot reach point or the
4097 scroll margin within a reasonable number of screen lines.
4098 Fixes point position in window under scroll-up/down-aggressively when
4099 point is positioned many lines beyond the window top/bottom.
4102 * ralloc.c (relinquish): If real_morecore fails to return memory
4103 to the system, don't crash; instead, leave the last heap
4104 unchanged and return. (Bug#12774)
4106 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4108 * lisp.h (AUTOLOADP): New macro.
4109 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
4110 * data.c (Ffset): Remove special ad-advice-info handling.
4111 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
4113 (Finteractive_form): Simplify.
4114 (Fquo): Don't insist on having at least 2 arguments.
4115 (Qdefalias_fset_function): New var.
4117 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4119 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
4121 * nsfont.m (Qcondensed, Qexpanded): New variables.
4122 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
4123 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4125 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4127 Fix recently introduced crash on MS-Windows (Bug#12839).
4128 * w32term.h (struct scroll_bar): Use convenient header.
4129 (SCROLL_BAR_VEC_SIZE): Remove.
4130 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4132 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4134 Tweak last vectorlike_header change.
4135 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4136 vectorlike object on the free list. This is introduced to avoid
4137 some (but not all) pointer casting and aliasing problems, see
4138 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4139 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
4141 (xvectype, xvecsize): Use them to examine Lisp_Object values.
4143 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4145 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4146 been removed, so remove them here also.
4148 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4150 * doc.c (Fdocumentation): Handle new property
4151 dynamic-docstring-function to replace the old ad-advice-info.
4153 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4155 * fns.c (Qeql, hashtest_eq): Now static.
4157 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4159 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4160 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4161 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
4162 * buffer.c (compare_overlays): Use XLI rather than XHASH.
4164 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
4166 Use same hash function for hashfn_profiler as for hash_string etc.
4167 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4168 * lisp.h (sxhash_combine): New inline function, with the contents
4169 of the old SXHASH_COMBINE.

4171 special hash function containing a comparison that always yields 1.
4173 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4175 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4176 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4177 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4180 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4182 * image.c (xpm_make_color_table_h): Fix compiler error because
4183 make_hash_table changed.
4185 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4187 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4189 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4191 Use ad-hoc comparison function for the profiler's hash-tables.
4192 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4193 (make_log): Use them.
4194 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4195 call Fequal any more.

4204 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4205 (hash_lookup, hash_remove_from_table): Move assertion checking of
4206 hashfn result here. Check hash-equality before calling cmpfn.

4216 2012-11-08 Eli Zaretskii <eliz@gnu.org>
4218 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4219 value of w32-scroll-lock-modifier is neither nil nor one of the
4220 known key modifiers. (Bug#12806)
4222 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4224 Shrink struct vectorlike_header to the only size field.
4225 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4227 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4228 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4229 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4230 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4231 information from the vector header. Adjust comment.

4243 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4244 (Fmake_bool_vector): Likewise.

4246 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4247 (large_vectors): Change type to struct large_vector.
4248 (allocate_vector_from_block): Simplify.
4249 (PSEUDOVECTOR_NBYTES): Replace with...
4250 (vector_nbytes): ...new function. Adjust users.

4252 (allocate_vectorlike): Likewise.
4253 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4254 Add easserts. Adjust XSETPVECTYPESIZE usage.
4255 (allocate_buffer): Use BUFFER_PVEC_INIT.
4256 (live_vector_p): Adjust to match large vector.
4257 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4258 * buffer.h (struct buffer): Add next member.
4259 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4261 (FOR_EACH_BUFFER): Adjust to match struct buffer change.

4267 (xvecsize): New command.
4269 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4271 * keyboard.c (event_to_kboard): Do not dereference
4272 frame_or_window field of SELECTION_REQUEST_EVENT
4273 and SELECTION_CLEAR_EVENT events (Bug#12814).
4274 * xterm.h (struct selection_input_event): Adjust comment.
4276 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4278 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4279 such as Scroll Lock, if the respective keys are treated as
4280 function keys, not as modifiers. This avoids destroying non-ASCII
4281 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4283 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4285 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4287 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4289 Restore some duplicate definitions (Bug#12814).
4290 This undoes part of the 2012-11-03 changes. Some people build
4291 with plain -g rather than with -g3, and they need the duplicate
4292 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4293 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4294 Define as macros, as well as as enums or as constants.
4296 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4298 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4299 to keypad keys (Bug#12816).
4301 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4303 Minor adjustments of recently-changed frame functions.
4304 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4305 known to be a frame (we're in the FRAMEP branch).
4306 * lisp.h (Qframep): Remove decl. frame.h declares this.
4307 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4308 since they're meant for Lisp fixnum values.
4310 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4312 * window.c (Fwindow_combination_limit): Revert to the only
4313 required argument and adjust docstring as suggested in
4314 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4315 by Martin Rudalics <rudalics@gmx.at>.
4317 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4319 Widely used frame validity and checking functions.
4320 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4321 * frame.c (decode_live_frame, decode_any_frame): New functions.
4322 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4323 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4324 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

4331 (frame_buffer_list, frame_buffer_predicate): Remove.
4332 * lisp.h (frame_buffer_predicate): Remove prototype.
4333 * buffer.c (Fother_buffer): Use decode_any_frame.
4334 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4335 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4336 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4337 (Fclose_font, Ffont_info): Use decode_live_frame.
4338 * fontset.c (check_fontset_name): Likewise.
4339 * terminal.c (Fframe_terminal): Likewise.
4340 * w32fns.c (check_x_frame): Likewise.
4341 * window.c (Fminibuffer_window, Fwindow_at)
4342 (Fcurrent_window_configuration): Likewise.
4343 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4344 Likewise. Allow zero number of arguments. Adjust docstring.
4345 * dispnew.c (Fredraw_frame): Likewise.
4346 * xfaces.c (frame_or_selected_frame): Remove.
4347 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4348 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4349 (Fframe_face_alist): Use decode_live_frame.
4350 * xfns.c (check_x_frame): Likewise.
4352 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4354 * window.c (quad): New function.
4355 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4356 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4357 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4358 (Fwindow_line_height): Use it.
4359 (Fwindow_fringes): Use list3.
4360 (Fwindow_scroll_bars): Use list4.
4361 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4362 (Fwindow_combination_limit): Allow zero number of arguments.
4364 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4366 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4368 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4369 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4370 file descriptor 2 for standard error. (Bug#12805)
4372 2012-11-05 Chong Yidong <cyd@gnu.org>
4374 * process.c (wait_reading_process_output): Revert previous change.
4376 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4378 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4379 This removes code that has been obsolete since around 1990.
4380 * callproc.c (Fcall_process):
4382 * process.c (create_process):
4383 * term.c (dissociate_if_controlling_tty):
4384 Assume setsid exists.
4385 * callproc.c (child_setup): Assume setpgid exists and behaves as
4386 per POSIX.1-1988 or later.
4387 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4388 * emacs.c (shut_down_emacs):
4389 * sysdep.c (sys_suspend, init_foreground_group):
4390 Assume getpgrp behaves as per POSIX.1-1998 or later.
4391 * msdos.c (setpgrp): Remove.
4392 (tcgetpgrp, setpgid, setsid): New functions.
4393 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4394 * term.c (no_controlling_tty): Remove; unused.
4395 * w32proc.c (setpgrp): Remove.
4396 (setsid, tcgetpgrp): New functions.
4398 Simplify by assuming __fpending.
4399 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4400 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4401 Do not assume that __fpending's result fits in int.
4403 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4405 Remove EMACS_OUTQSIZE+sleep hack.
4406 * dispnew.c (update_frame_1): Remove hack for terminals slower
4407 than 2400 bps, which throttled Emacs by having it sleep.
4408 This code hasn't worked since at least 2007, when the multi-tty stuff
4409 was added, and anyway those old terminals are long dead.
4410 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4411 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4413 Fix data-loss with --version (Bug#9574).
4414 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4415 as we can't assume that emacs_strerror is initialized, and strerror
4416 is good enough here.
4417 (main): Invoke atexit earlier, to catch earlier instances of
4418 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4420 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4422 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4423 (keyDown): Remap keypad keys to X11 virtual key codes.
4425 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4427 Fix data-loss with --batch (Bug#9574).
4428 * emacs.c: Include <close-stream.h>.
4429 (close_output_streams): New function.
4430 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4431 and handles errors appropriately.
4432 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4435 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4436 The symptom is a diagnostic "GLib-WARNING **: In call to
4437 g_spawn_sync(), exit status of a child process was requested but
4438 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4439 waitpid(), so exit status can't be returned." The diagnostic
4440 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4441 The real bug is a race condition between Emacs and glib: Emacs
4442 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4443 so that glib can't find it. Work around the bug by invoking
4444 waitpid only on subprocesses that Emacs itself creates.
4445 * process.c (create_process, record_child_status_change):
4446 Don't use special value -1 in pid field, as the caller now must
4447 know the pid rather than having the callee infer it.
4448 The inference was sometimes incorrect anyway, due to another race.
4449 (create_process): Set new 'alive' member if child is created.
4450 (process_status_retrieved): New function.
4451 (record_child_status_change): Use it.
4452 Accept negative 1st argument, which means to wait for the
4453 processes that Emacs already knows about. Move special-case code
4454 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4455 processes that have already been waited for, by testing and
4456 clearing new 'alive' member.
4457 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4458 now does this internally.
4459 (handle_child_signal): Let record_child_status_change do all
4460 the work, since we do not want to reap all exited child processes,
4461 only the child processes that Emacs itself created.
4462 * process.h (Lisp_Process): New boolean member 'alive'.
4464 Omit duplicate definitions no longer needed with gcc -g3.
4465 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4466 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4467 Define only as macros. There's no longer any need to also define
4468 these symbols as enums or as constants, since we now assume
4469 gcc -g3 when debugging.
4471 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4473 * lisp.mk: Adjust comments to the fact that term/internal is now
4474 loaded from loadup.el.
4476 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4477 (msdos_fatal_signal): New function.
4478 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4481 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4482 for GCC versions before 4.
4483 (emacs_raise): Define to call msdos_fatal_signal.
4485 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4486 iterator when starting in the middle of a display or overlay
4489 2012-11-03 Chong Yidong <cyd@gnu.org>
4491 * process.c (wait_reading_process_output): Clean up the last
4494 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4496 * process.c (wait_reading_process_output): Avoid a race condition

4503 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4505 * frame.h (struct frame): Drop can_have_scroll_bars member
4506 which is meaningless for a long time. Adjust comments.
4507 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4508 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4510 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4512 * window.c (decode_next_window_args): Update window arg after
4513 calling decode_live_window and so fix crash reported at
4514 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4515 by Juanma Barranquero <lekktu@gmail.com>.
4516 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4517 * font.c (Ffont_at): Likewise.
4519 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4521 * widget.c (resize_cb): New function.
4522 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4523 (EmacsFrameResize): Check if all is up to date before changing frame
4526 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4528 Implement backtrace output for fatal errors on MS-Windows.
4529 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4530 (BACKTRACE_LIMIT_MAX): New macro.
4531 (w32_backtrace): New function.
4532 (emacs_abort): Use w32_backtrace when the user chooses not to
4533 attach a debugger. Update the text of the abort dialog.
4535 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4537 Window-related stuff cleanup here and there.
4538 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4539 Use decode_any_window.
4540 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4541 * xdisp.c (Fformat_mode_line): Likewise.
4542 * font.c (Ffont_at): Use decode_live_window.

4547 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4548 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4551 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4553 Remove pad from struct input_event.
4554 * termhooks.h (struct input_event): Remove padding field.
4556 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4557 member is never cons for a long time. Adjust comment.
4558 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4559 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4560 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4561 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4563 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4565 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4567 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4569 Fix crash when using Emacs as commit editor for git (Bug#12697).
4570 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4571 and it is configured in conf_post.h.
4572 (Fcall_process): Don't invoke both setsid and setpgid; the former
4573 is enough, if it exists.
4574 * callproc.c (Fcall_process, child_setup):
4575 * process.c (create_process): Use setpgid.
4576 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4578 * dispnew.c (init_display): Initialize the foreground group
4579 if we are running a tty display.
4580 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4581 * lisp.h (init_foreground_group): New decl.
4582 * sysdep.c (inherited_pgroup): New static var.
4583 (init_foreground_group, tcsetpgrp_without_stopping)
4584 (narrow_foreground_group, widen_foreground_group): New functions.
4585 (init_sys_modes): Narrow foreground group.
4586 (reset_sys_modes): Widen foreground group.

4592 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4594 * minibuf.c (read_minibuf): Restore current buffer since
4595 choose_minibuf_frame calling Fset_frame_selected_window may
4596 change it (Bug#12766).
4598 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4600 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4602 2012-10-30 Kenichi Handa <handa@gnu.org>
4604 * font.c (Ffont_at): If WINDOW is specified and it is not
4605 displaying the current buffer, signal an error.
4607 2012-10-29 Daniel Colascione <dancol@dancol.org>
4609 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4610 In preparation for fixing bug#12739, move these functions from
4613 * coding.h, coding.c: ... to here, and compile them only when
4614 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4615 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4617 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4619 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4620 (timer_loop, getitimer, setitimer): Use it instead of
4621 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4623 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4626 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4628 * nsterm.m (NO_APPDEFINED_DATA): New define.
4629 (last_appdefined_event_data): New variable
4630 (last_appdefined_event): Remove.
4631 (ns_select): Initialize t from last_appdefined_event_data instead
4632 of [last_appdefined_event data1].
4633 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4634 remove last_appdefined_event (Bug#12698).
4636 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4638 * frame.c (x_set_font): Catch internal error.
4640 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4642 Avoid overflow in w32 implementation of interval timers.
4643 When possible, for ITIMER_PROF count only times the main thread
4645 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4646 'volatile ULONGLONG' types. All the other data which was
4647 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4648 (GetThreadTimes_Proc): New typedef.
4649 (w32_get_timer_time): New function, returns a suitable time value
4651 (timer_loop): Enter critical section when accessing ULONGLONG
4652 values of the itimer_data struct, as these accesses are no longer
4653 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4654 Remove unused variable.
4655 (init_timers): Initialize s_pfn_Get_Thread_Times.
4656 (start_timer_thread): Don't assign itimer->caller_thread here.
4657 (getitimer): Assign itimer->caller_thread here.
4658 (setitimer): Always call getitimer to get the value of ticks_now.

4663 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4664 mouse movement events if the menu bar is active. This avoids
4665 producing a busy "hour-glass" cursor by Windows if the mouse
4666 pointer is positioned over a tooltip shown for some menu item.
4668 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4670 Don't assume process IDs fit in int.
4671 * emacs.c (shut_down_emacs) [!DOS_NT]:
4672 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4673 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4674 Use pid_t, not int, to store process IDs, as 'int'
4675 is not wide enough on a few platforms (e.g., AIX and IRIX).
4677 2012-10-23 Kenichi Handa <handa@gnu.org>
4679 The following change is to make face-font-rescale-alist work
4680 correctly for non-ASCII fonts.
4682 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4683 (font_open_for_lface): Handle Vface_font_rescale_alist.
4685 2012-10-23 Chong Yidong <cyd@gnu.org>
4687 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4689 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

4698 2012-10-21 Glenn Morris <rgm@gnu.org>
4700 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4702 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4704 Port to OpenBSD 5.1.
4705 * frame.c (Fmouse_position, Fmouse_pixel_position):
4706 * xdisp.c (produce_stretch_glyph):
4707 Declare local vars only when they're needed.
4708 This is clearer and avoids a warning on OpenBSD about unused vars.

4710 This is safer, and avoids OpenBSD warnings about unused vars.
4711 * keyboard.c (record_menu_key): Remove unnecessary decl.
4712 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4713 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4714 as our definition clashes with OpenBSD's.
4715 * xfaces.c (load_face_colors, check_lface_attrs)
4716 (get_lface_attributes_no_remap, get_lface_attributes)
4717 (lface_fully_specified_p, x_supports_face_attributes_p)
4718 (tty_supports_face_attributes_p, face_fontset, realize_face)
4719 (realize_x_face, realize_tty_face):
4720 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4721 merely Lisp_Object *. This is more informative and avoids
4722 a warning on OpenBSD about accessing beyond an object's size.
4724 2012-10-20 Chong Yidong <cyd@gnu.org>
4726 * lread.c (Fload): Doc fix (Bug#12592).

4730 * font.c (Ffont_at): Fix previous change.
4732 2012-10-19 Eli Zaretskii <eliz@gnu.org>
4734 * puresize.h (BASE_PURESIZE): Bump the base value to 1700000.
4735 See http://lists.gnu.org/archive/html/emacs-devel/2012-10/msg00593.html

4752 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4753 (staticpro): If we run out of staticpro slots, die with an
4754 informative error instead of just calling emacs_abort.
4756 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4758 Fix two flaws reported by Dmitry Antipov.

5013 since unsigned is guaranteed to have that behavior and signed is not.

5015 (get_input_pending): Remove first argument, since it was always
5016 the same pointer-to-int (now pointer-to-boolean) &input_pending,
5017 and behave as if it had that value. Return new value of
5018 input_pending. All callers changed.
5019 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
5020 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

5063 match what GetLastError returns. Explain why the function is
5066 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
5067 'is_tooltip_frame', to avoid confusion with its global namesake.
5069 2012-10-08 Daniel Colascione <dancol@dancol.org>
5071 * xdisp.c (start_hourglass): Call w32_note_current_window when
5072 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
5073 build that caused Emacs to display the hourglass cursor forever.
5075 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
5076 which is broken under remote desktop, calculate the number of
5077 colors available for a display based on the display's number of
5078 planes and number of bits per pixel per plane. (bug#10397).
5080 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
5082 * nsfont.m (Vfonts_in_cache): New variable.
5083 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
5084 are used. Add cached fonts to Vfonts_in_cache.
5085 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
5087 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
5089 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
5091 (FONT_H): Define after FRAME_H.
5092 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
5093 Update dependencies.
5095 * w32term.c: Remove leftover declaration of keyboard_codepage.
5097 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5099 * makefile.w32-in (FONT_H): Add $(FRAME_H).
5100 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
5101 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
5102 (GLOBAL_SOURCES): Add cygw32.c.
5103 ($(BLD)/unexw32.$(O)):
5105 ($(BLD)/w32console.$(O)):
5106 ($(BLD)/w32fns.$(O)):
5107 ($(BLD)/w32heap.$(O)):
5108 ($(BLD)/w32menu.$(O)):
5109 ($(BLD)/w32proc.$(O)): Add w32common.h.
5111 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
5113 (x_to_w32_color): Don't modify the argument, modify a copy instead.
5115 2012-10-08 Daniel Colascione <dancol@dancol.org>
5117 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
5118 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
5119 accidental message numbering hole. Change other messages to
5122 * w32select.h (HAVE_W32SELECT): Remove.
5124 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
5125 w32common.h instead of w32heap.h.
5127 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
5128 (get_allocation_unit, get_processor_type, get_w32_major_version)
5129 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5130 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5131 (OS_NT, os_subtype, cache_system_info): Move declarations to
5134 * w32heap.c: Include w32common.h.
5135 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5136 (w32_minor_version, w32_build_number, w32_subtype):
5137 Remove duplicate definitions.
5139 * w32fns.c: Include w32common.h; include w32heap.h only in
5142 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5143 Use `report_file_error' instead of `error' in order to better
5144 inform users of what went wrong. Increase NTGUI_UNICODE file
5145 dialog box file name length to 32k, the maximum allowed by the NT
5148 * w32common.h: New file.
5149 (ROUND_UP, ROUND_DOWN, get_page_size)
5150 (get_allocation_unit, get_processor_type, get_w32_major_version)
5151 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5152 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5153 (OS_NT, os_subtype, cache_system_info): Move here.
5155 * unexw32.c, unexcw.c: Include w32common.h.
5157 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5158 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5159 to call syms_of_w32select.
5161 * cygw32.h: Remove obsolete EXFUN declarations.
5163 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5165 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5166 of w32inevt.o from SOME_MACHINE_OBJECTS.
5168 2012-10-08 Daniel Colascione <dancol@dancol.org>
5170 * image.c: Permanent fix for JPEG compilation issue --- limit
5171 jpeglib `boolean' redefinition to Cygwin builds.
5173 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5175 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5177 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5180 2012-10-08 Daniel Colascione <dancol@dancol.org>
5182 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5183 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5184 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5185 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5186 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5187 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5188 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5189 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5190 now a supported configuration.
5192 * Makefile.in: consolidate image variables into LIBIMAGE; add
5193 W32_OBJ and W32_LIBS. Compile new files.
5196 (_DebPrint) declare tracing facility for W32 debugging. We need
5197 to unify tracing later.
5199 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5200 unconditional use of W32 Unicode functions. Cygwin runs only on
5201 100% Unicode operating systems.
5203 * cygw32.c: New file. Define Cygwin-specific facilities.
5204 (Fcygwin_convert_path_to_windows)
5205 (Fcygwin_convert_path_from_windows): New user functions for
5206 accessing Cygwin path-munging routines.
5208 * cygw32.h: New file.
5209 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5210 UTF-16LE strings temporarily inside non-Lisp-visible string
5213 (w32_strerror): Just what it says on the tin.
5215 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5216 also run for Cygwin; both systems have the same problem with using
5217 GUI facilities in a forked child. Also call syms_of_cygw32,
5218 syms_of_w32select in correct places.
5220 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5221 needs fork-then-exec for daemon launching.
5223 * font.h: Include frame.h.
5225 * image.c: Use the image library cache machinery only when we're
5226 compiling for native WINDOWSNT; Cygwin can use shared libraries
5227 like any other Unixlike system.
5229 * keyboard.c: Clarify a comment regarding the input loop.
5231 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5232 functions directly instead of trying to detect at runtime that our
5233 host operating system supports them. We make this change for two
5234 reasons: Cygwin lacks support for the multibyte character
5235 conversion functions used by the legacy menu code, and Cygwin
5236 never needs to rely on non-Unicode APIs.
5238 * unexw32.c (hinst): Declare extern.
5240 * w32.c: Change header order;
5241 (w32_strerror): Move to w32fns.c because we need it for
5242 non-WINDOWSNT builds.
5244 * w32.h: Add #error macro to make sure we don't include w32.h for
5245 Cygwin builds. Remove w32select declarations.
5247 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5248 w32fns.c. w32console.c is WINDOWSNT-only.
5250 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5251 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5253 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5254 (w32_major_version, w32_minor_version, w32_build_number)
5255 (os_subtype, sound_type): Define here
5256 (w32_defined_color): Make color parameter const for consistency
5257 with other _defined_color functions.
5258 (w32_createwindow): Unconditionally call w32_init_class instead of
5259 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5260 through the code is complex and unnecessary because class
5261 registration is practically free.
5262 (w32_name_of_message): New EMACSDEBUG-only function.
5263 (Fset_message_beep): Move here
5264 (Fx_open_connection): Require that the display name for Windows be
5265 "w32" for consistency, emacsclient disambiguation, and maybe, one
5266 day, multi-window-system support.
5267 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5268 Cygwin files for W32 GUI facilities, since these clearly don't
5269 expect Cygwin names.
5270 (_DebPrint): Define.
5271 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5272 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5273 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5274 (w32_last_error): Remove.
5276 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5278 * w32heap.c (syspage_mask): Declare here.
5279 (cache_system_info): Remove.
5281 * w32inevt.c (faked_key): Define globally, not statically.
5282 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5283 (w32_console_toggle_lock_key): Move to w32fns.c.
5285 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5287 * w32proc.c (_DebPrint): Move to w32fns.c.
5288 * w32select.c: Include string.h, stdio.h for Cygwin.
5289 * w32select.h: New File.
5291 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5293 (w32_message_fd): New variable. Under Cygwin, holds the file
5294 descriptor the system used to tell us about pending thread
5297 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5298 that prevented compilation under non-WINDOWSNT systems.
5300 (w32_initialize): Open /dev/windows and assign it to
5301 w32_message_fd. Provide w32 feature.
5303 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5304 (WM_EMACS_INPUT_READY): add.
5305 (prepend_msg, w32_message_fd): Declare globally.
5308 (keyboard_handle): Use only when WINDOWSNT.
5309 (notify_msg_ready): New function. Posts a message to the main
5310 thread's message queue under CYGWIN, which wakes up the main
5311 thread from select(2) by making the /dev/windows file descriptor
5312 ready. Under WINDOWSNT, it sets an event the same way the old
5315 (post, prepend_msg): Actually call notify_msg_ready instead of
5316 setting the input event directly.
5318 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5320 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5321 but it still has blocs in it, don't return it to the system,
5322 instead of aborting. (Bug#12402)
5324 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5326 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5328 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5329 MAC_OS_X_VERSION_10_6.
5330 (syms_of_nsterm): Remove comment about Panther and above for
5332 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5333 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5334 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5336 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5337 MAC_OS_X_VERSION_10_4.
5339 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5340 MAC_OS_X_VERSION_10_2.
5342 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5344 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5345 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5347 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5348 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5349 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5350 Remove ns_in_resize check.
5351 (ns_clear_frame_area): Remove resize handle code.
5353 * nsfns.m (ns_in_resize): Remove.
5354 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5355 Remove ns_in_resize check.
5357 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5359 Improve sys_siglist detection.
5360 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5361 defined as a macro, as is done in Solaris.
5362 (sys_siglist_entries): New macro.
5363 (save_strsignal): Use it.
5364 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5365 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5367 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5369 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5370 fullscreen/Fullscreen.
5372 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5373 tobar_height is new.
5375 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5376 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5377 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5378 (windowDidResize:): Check for correct window if old style fullscreen.
5379 Capitalize word in comment. Remove incorrect comment.
5380 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5381 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5382 error in drawing background.
5383 (toggleFullScreen:): Remove comment. Rearrange calls.
5384 Set toolbar values to zero, save old height in tobar_height.
5385 Restore tool bar height when leaving fullscreen.
5386 (canBecomeMainWindow): New function.
5388 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5390 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5392 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5394 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5396 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5397 that time stamps of directories could also be changed.
5398 Don't request the too broad GENERIC_WRITE, only the more restrictive
5399 FILE_WRITE_ATTRIBUTES access rights.
5401 * fileio.c (Fset_file_times): Special-case ignoring errors for
5402 directories only on MSDOS, not on MS-Windows.
5404 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5406 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5408 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5410 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5411 see whether CreateFile failed.
5413 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5415 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5416 to avoid similar races.
5417 * keyboard.c (pending_signals): Now bool, not int.
5419 Port timers to OpenBSD, plus check for timer failures.
5420 OpenBSD problem reported by Han Boetes.
5421 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5423 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5424 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5425 like OpenBSD, which has timer_settime but does not declare it.
5426 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5427 whether to use itimerspec-related primitives. All uses of
5428 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5430 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5432 * profiler.c (handle_profiler_signal): Fix a malloc race
5433 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5435 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5437 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5439 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5441 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5442 consistent with the change in return value of 'safe_strsignal'.
5444 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5446 Prefer plain 'static' to 'static inline' (Bug#12541).
5447 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5448 (bidi_set_sor_type, bidi_push_embedding_level)
5449 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5450 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5451 (bidi_cache_search, bidi_cache_ensure_space)
5452 (bidi_cache_iterator_state, bidi_cache_find)
5453 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5454 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5455 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5456 Now 'static', not 'static inline'.
5458 Count overruns when profiling; change units to ns.
5459 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5460 Give extra weight to samples after overruns, to attempt to count
5461 the time more accurately.
5462 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5463 the underlying primitives nominally do ns.
5464 (Fprofiler_cpu_start): Document the change. Mention that
5465 the sampling intervals are only approximate.
5467 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5469 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5471 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5472 case for the special 0 coding-system.
5474 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5475 (Fmake_overlay): Remove redundant tests.
5476 (fix_start_end_in_overlays): Remove redundant recentering.
5478 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5480 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5481 Update dependencies.
5483 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5485 Fix a malloc race condition involving strsignal.
5486 A signal can arrive in the middle of a malloc, and Emacs's signal
5487 handler can invoke strsignal, which can invoke malloc, which is
5488 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5489 Fix it by altering the signal handler so that it does not invoke
5491 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5492 * process.c (status_message): Use const pointer, in case strsignal
5493 is #defined to safe_strsignal.
5494 * sysdep.c (sys_siglist, init_signals): Always define and
5495 initialize a substitute sys_siglist if the system does not define
5496 one, even if HAVE_STRSIGNAL.
5497 (safe_strsignal): Rename from strsignal. Always define,
5498 using sys_siglist. Return a const pointer.
5499 * syssignal.h (safe_strsignal): New decl.
5500 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5502 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5504 * w32proc.c (timer_loop): Fix code that waits for timer
5505 expiration, to avoid high CPU usage.
5507 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5509 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5510 (sweep_weak_table): Remove redundant prototypes.
5512 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5514 * emacs.c: Move the inclusion of TERM_HEADER after including
5515 windows.h on WINDOWSNT. This avoids compilation problems with
5518 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5520 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5521 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5522 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5523 as the previous version used 'void *'.
5525 * ralloc.c (ROUNDUP): Fix last change.
5526 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5529 * w32proc.c <disable_itimers>: New static flag.
5530 (init_timers): Initialize it to zero, after creating the critical
5531 sections used by the timer threads.
5532 (term_timers): Set to 1 before deleting the critical sections.
5533 (getitimer, setitimer): If disable_itimers is non-zero, return an
5534 error indication without doing anything. Reported by Fabrice
5535 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5536 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5538 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5541 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5542 term_ntproc after all the other bookkeeping, to get timers working
5543 as long as possible.
5545 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5547 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5548 Suggested by Juri Linkov in
5549 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5551 Prefer plain 'static' to 'static inline' (Bug#12541).
5552 With static functions, modern compilers inline pretty well by
5553 themselves; advice from programmers often hurts as much as it helps.
5554 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5555 this change shrinks the text size of the Emacs executable by 1.1%
5556 without affecting CPU significantly in my benchmark.

5929 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5930 Since this stuff is now private to charset.c, there's no need for
5931 a public macro and no need to inline by hand.

5992 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
5993 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
5995 * w32.h (Vlibrary_cache): Do not declare.
5997 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5999 * w32proc.c (sys_signal): Handle all signals defined by the
6000 MS-Windows runtime, not just SIGCHLD. Actually install the signal
6001 handlers for signals supported by Windows. Don't override
6002 term_ntproc as the handler for SIGABRT.
6003 (sigaction): Rewrite to call sys_signal instead of duplicating its
6005 (sys_kill): Improve commentary.
6007 * w32.c (term_ntproc): Accept (and ignore) one argument, for
6008 consistency with a signature of a signal handler. All callers
6010 (init_ntproc): Accept an argument DUMPING. If dumping, don't
6011 install term_ntproc as a signal handler for SIGABRT, as that
6012 should be done by the dumped Emacs.
6014 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
6016 * w32select.c (term_w32select): Protect against repeated
6017 invocation by setting clipboard_owner to NULL after calling
6020 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
6021 and term_ntproc to their modified signatures.
6023 * character.c (char_string, string_char): Remove calls to
6024 MAYBE_UNIFY_CHAR. See the discussion starting at
6025 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
6028 2012-09-25 Chong Yidong <cyd@gnu.org>
6030 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
6032 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
6034 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
6035 when encountering an unknown bytecode.
6037 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
6039 image.c, indent.c: Use bool for booleans.
6040 * dispextern.h (struct image_type): Members valid_p, load, init
6041 now return bool, not int. All uses changed.
6042 * image.c: Omit unnecessary static decls.
6043 (x_create_bitmap_mask, x_build_heuristic_mask):
6044 Return void, not int, since callers don't care about the return value.

6075 2012-09-24 Chong Yidong <cyd@gnu.org>
6077 * chartab.c (Fset_char_table_default): Obsolete function removed.
6079 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6081 Move pid_t related decls out of lisp.h.
6082 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6083 (interruptible_wait_for_termination):
6084 Move these decls from lisp.h to syswait.h, since they use pid_t.
6085 Needed on FreeBSD; see Herbert J. Skuhra in
6086 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
6087 * callproc.c: Include syswait.h.

6105 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
6106 * xfns.c (Fx_show_tip) [USE_GTK]:
6107 Use bool for boolean.
6108 * gtkutil.c (xg_update_frame_menubar):
6109 * xmenu.c (update_frame_menubar):
6110 Return void, not int, since caller ignores return value.
6111 * gtkutil.c (xg_change_toolbar_position):
6114 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6116 * makefile.w32-in (BLOCKINPUT_H): Remove.

6133 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6135 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6136 fatal_error_backtrace.
6138 * w32proc.c (sys_kill): Undo last change: don't do anything when
6139 invoked to deliver SIGABRT to our own process. This is now
6140 handled by emacs_raise.
6142 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6144 * w32term.c (w32_read_socket): Remove leftover reference to
6145 interrupt_input_pending.
6147 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6149 Do not use SA_NODEFER.
6150 Problem reported by Dani Moncayo in
6151 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6153 * sysdep.c (emacs_abort): Do not reset signal handler.
6154 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6155 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6156 wanted even on POSIXish hosts, and it doesn't work on Windows.
6158 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6160 * xterm.c (x_term_init): Call fixup_locale before and after calling
6161 gtk_init (Bug#12392).
6163 2012-09-23 Chong Yidong <cyd@gnu.org>
6165 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6166 Vdynamic_library_alist.
6168 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6169 (Fgnutls_available_p): Caller changed.
6171 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6172 (Flibxml_parse_xml_region): Likewise.
6174 * dispextern.h (struct image_type): Remove arg from init function.
6176 * image.c (Finit_image_library, lookup_image_type)
6177 (define_image_type): Remove now-unneeded second arg.
6178 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6179 (init_tiff_functions, init_gif_functions, init_svg_functions):
6180 Arglist and w32_delayed_load calling convention changed.
6181 (gs_type): Remove init_gs_functions; there is no such function.
6182 (valid_image_p, make_image): Fix caller to lookup_image_type.
6184 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6186 Simplify and avoid signal-handling races (Bug#12471).
6188 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6189 Avoid recursive loop if there's a fatal error in the function itself.
6190 * atimer.c (pending_atimers):
6191 * blockinput.h: Don't include "atimer.h"; no longer needed.
6192 (interrupt_input_pending): Remove. All uses removed.
6193 pending_signals now counts both atimers and ordinary interrupts.
6194 This is less racy than having three separate pending-signal flags.
6195 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6197 Rename from their upper-case counterparts BLOCK_INPUT,
6198 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6199 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6200 This makes it easier to access volatile variables more accurately.
6201 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6202 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6203 that's more reliable if the code is buggy and sets
6204 interrupt_input_blocked to a negative value. All uses changed.
6205 * atimer.c (deliver_alarm_signal):
6206 Remove. No need to deliver this to the parent; any thread can
6207 handle this signal now. All uses replaced by underlying handler.
6208 * atimer.c (turn_on_atimers):
6209 * dispnew.c (handle_window_change_signal):
6210 * emacs.c (handle_danger_signal):
6211 * keyboard.c (kbd_buffer_get_event):
6212 Don't reestablish signal handler; not needed with sigaction.
6213 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6215 Rework to avoid unnecessary accesses to volatile variables.
6216 (UNBLOCK_INPUT_TO): Now a function.
6217 (totally_unblock_input, unblock_input): New decls.
6218 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6219 (init_data): Remove. Necessary stuff now done in init_signal.
6220 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6221 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6222 (fatal_error_code): Remove; no longer needed.
6223 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6224 it doesn't always backtrace. All uses changed. No need to reset
6225 signal to default, since sigaction and/or die does that for us now.
6226 Use emacs_raise (FOO), not kill (getpid (), FOO).
6227 (main): Check more-accurately whether we're dumping.
6228 Move fatal-error setup to sysdep.c
6229 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6230 * gtkutil.c (xg_get_file_name, xg_get_font):
6231 Remove no-longer-needed signal-mask manipulation.
6232 * keyboard.c, process.c (POLL_FOR_INPUT):
6233 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6234 * keyboard.c (read_avail_input): Remove.
6235 All uses replaced by gobble_input.
6236 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6237 (kbd_buffer_store_event_hold, gobble_input):
6238 (record_asynch_buffer_change) [USABLE_SIGIO]:
6239 (store_user_signal_events):
6240 No need to mess with signal mask.
6241 (gobble_input): If blocking input and there are terminals, simply
6242 set pending_signals to 1 and return. All hooks changed to not
6243 worry about whether input is blocked.
6244 (process_pending_signals): Clear pending_signals before processing
6245 them, in case a signal comes in while we're processing.
6246 By convention callers now test pending_signals before calling us.
6247 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6248 New functions, to support changes to blockinput.h.
6249 (handle_input_available_signal): Now extern.
6250 (reinvoke_input_signal): Remove. All uses replaced by
6252 (quit_count): Now volatile, since a signal handler uses it.
6253 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6254 All callers changed. Block SIGINT only if not already blocked.
6255 Clear sigmask reliably, even if Fsignal returns, which it can.
6256 Omit unnecessary accesses to volatile var.
6257 (quit_throw_to_read_char): No need to restore sigmask.
6258 * keyboard.c (gobble_input, handle_user_signal):
6259 * process.c (wait_reading_process_output):
6260 Call signal-handling code rather than killing ourselves.
6261 * lisp.h: Include <float.h>, for...
6262 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6263 (pending_signals): Now volatile.
6264 (syms_of_data): Now const if IEEE floating point.
6265 (handle_input_available_signal) [USABLE_SIGIO]:
6266 (terminate_due_to_signal, record_child_status_change): New decls.
6267 * process.c (create_process): Avoid disaster if memory is exhausted
6268 while we're processing a vfork, by tightening the critical section
6270 (send_process_frame, process_sent_to, handle_pipe_signal)
6271 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6273 (send_process): No need for setjmp/longjmp any more, since the
6274 SIGPIPE stuff is now gone. Instead, report an error if errno
6276 (record_child_status_change): Now extern. PID and W are now args.
6277 Return void, not bool. All callers changed.
6278 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6279 Remove. All uses removed. This bug should be fixed now in a
6281 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6282 and record the child status change directly. This avoids the
6283 need to futz with the signal mask.
6284 (process_fatal_action): Move here from emacs.c.
6285 (emacs_sigaction_flags): New function, containing
6286 much of what used to be in emacs_sigaction_init.
6287 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6288 caught by emacs, to make races less likely.
6289 (deliver_process_signal): Rename from handle_on_main_thread.
6291 (BACKTRACE_LIMIT_MAX): Now at top level.
6292 (thread_backtrace_buffer, threadback_backtrace_pointers):
6294 (deliver_thread_signal, deliver_fatal_thread_signal):
6295 New functions, for more-accurate delivery of thread-specific signals.
6296 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6297 (deliver_arith_signal): Handle in this thread, not
6298 in the main thread, since it's triggered by this thread.
6299 (maybe_fatal_sig): New function.
6300 (init_signals): New arg DUMPING so that we can be more accurate
6301 about whether we're dumping. Caller changed.
6302 Treat thread-specific signals differently from process-general signals.
6303 Block all signals while handling fatal error; that's safer.
6304 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6306 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6307 Ignore SIGPIPE unless batch.
6308 (emacs_backtrace): Output backtrace for the appropriate thread,
6309 which is not necessarily the main thread.
6310 * syssignal.h: Include <stdbool.h>.
6311 (emacs_raise): New macro.
6312 * xterm.c (x_connection_signal): Remove; no longer needed
6313 now that we use sigaction.
6314 (x_connection_closed): No need to mess with sigmask now.
6315 (x_initialize): No need to reset SIGPIPE handler here, since
6316 init_signals does this for us now.
6318 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6320 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6321 background rect may be larger (Bug#12245).
6323 2012-09-23 Chong Yidong <cyd@gnu.org>
6325 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6327 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6329 * .gdbinit: Just stop at fatal_error_backtrace.
6330 See Stefan Monnier's request in
6331 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6332 Remove no-longer-used query of system type.
6334 2012-09-22 Chong Yidong <cyd@gnu.org>
6336 * search.c (Freplace_match): Doc fix (Bug#12325).
6338 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6340 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6341 (Fline_end_position): Doc fix.
6343 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6345 2012-09-22 Chong Yidong <cyd@gnu.org>
6347 * dispextern.h (struct image_type): Add new slot, storing a type
6348 initialization function.
6350 * image.c (define_image_type): Call the image initializer function
6351 if it is defined. Arguments and return value changed.
6352 (valid_image_p, make_image): Callers changed.
6353 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6354 (gif_type, imagemagick_type, svg_type, gs_type):
6355 Add initialization functions.
6356 (Finit_image_library): Call lookup_image_type.
6357 (CHECK_LIB_AVAILABLE): Macro deleted.
6358 (lookup_image_type): Call define_image_type here, rather than via
6359 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6360 (syms_of_image): Move define_image_type calls for xbm_type and
6361 pbm_type to lookup_image_type.
6363 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6365 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6366 'idle_timers' from here ...
6367 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6368 lists, to avoid infloops when the timer does something stupid,
6369 like reinvoke itself with the same or smaller time-out.
6372 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6374 * window.c (Fsplit_window_internal): Handle only Qt value of
6375 Vwindow_combination_limit separately.
6376 (Qtemp_buffer_resize): New symbol.
6377 (Vwindow_combination_limit): New default value.
6380 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6382 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
6383 the new overlay string. (Bug#10159)
6385 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6387 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6388 or that fprintf is async-signal-safe. POSIX doesn't require
6391 2012-09-22 Chong Yidong <cyd@gnu.org>
6393 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6396 2012-09-22 Kenichi Handa <handa@gnu.org>
6398 * composite.c (composition_reseat_it): Handle the case that a
6399 grapheme cluster is not covered by a single font (Bug#12352).
6401 2012-09-21 Chong Yidong <cyd@gnu.org>
6403 * image.c (define_image_type): Avoid adding duplicate types to
6404 image_types (Bug#12463). Suggested by Jörg Walter.
6406 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6408 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6409 (print_load_command_name): Add case LC_DATA_IN_CODE.
6410 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
6412 2012-09-21 Glenn Morris <rgm@gnu.org>
6414 * eval.c (Frun_hook_with_args_until_success)
6415 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6417 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6419 * fileio.c (Ffile_selinux_context): Only call freecon when
6420 lgetfilecon succeeded.
6421 (Fset_file_selinux_context): Likewise. (Bug#12444)
6423 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6425 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6426 reordering, locate the cursor by calling set_cursor_from_row; if
6427 that fails, clear the desired glyph matrix before returning a
6428 failure indication to the caller. Fixes leaving garbled display
6429 when fast scrolling with a down-key. (Bug#12403)
6430 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6431 scrolling through multibyte text.
6433 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6435 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6436 calling mark_vectorlike since that's the one that marks the window.
6437 (mark_discard_killed_buffers): Mark the final cdr.
6438 * window.h (struct window): Move prev/next_buffers to the
6439 non-standard fields.
6440 * window.c (make_window): Initialize prev/next_buffers manually.
6442 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6444 Omit unused arg EXPECTED from socket hooks.
6445 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6446 * nsterm.m (ns_term_init):
6447 * termhooks.h (struct terminal.read_socket_hook):
6448 * w32inevt.c (w32_console_read_socket):
6449 * w32term.c (w32_read_socket):
6450 * xterm.c (XTread_socket):
6451 Omit unused arg EXPECTED. All callers changed.
6452 (store_user_signal_events): Return void, not int, since callers no
6453 longer care about the return value. All uses changed.
6455 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6457 * w32gui.h (XParseGeometry): Do not declare.
6459 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6461 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6462 Ignore 'expected'. See Eli Zaretskii in
6463 <http://bugs.gnu.org/12471#8> (last line).
6465 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6466 (XParseGeometry): Now static. Substitute extremal values for
6467 values that are out of range.
6469 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6471 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6473 * nsfns.m (XParseGeometry): Remove.
6474 (Fx_create_frame): Call x_set_offset to correctly interpret
6475 top_pos in geometry.
6477 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6478 (Fx_parse_geometry): If there is a space in string, call
6479 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6481 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6483 * search.c (scan_buffer): Use character positions in calls to
6484 region_cache_forward and region_cache_backward, not byte
6485 positions. (Bug#12196)
6487 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6488 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6490 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6491 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6492 emacs_blocked_malloc, now deleted.
6494 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6496 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6497 The workaround was for improving performance on Solaris 2.4, but
6498 is getting in the way now. Emacs will still work if someone is
6499 still running Solaris 2.4 in a museum somewhere; Sun dropped
6500 support for Solaris 2.4 in 2003.
6501 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6502 * process.c (create_process) [HAVE_WORKING_VFORK]:
6503 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6504 since Emacs no longer uses vfork on that platform.
6506 2012-09-17 Glenn Morris <rgm@gnu.org>
6508 * emacs.c: Use COPYRIGHT.
6510 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6512 Remove configure's --without-sync-input option (Bug#12450).
6513 When auditing signal-handling in preparation for cleaning it up,
6514 I found that SYNC_INPUT has race conditions and would be a real
6515 pain to fix. Since it's an undocumented and deprecated
6516 configure-time option, now seems like a good time to remove it.
6517 Also see <http://bugs.gnu.org/11080#16>.
6518 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6519 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6520 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6521 (malloc_hysteresis):
6522 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6523 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6524 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6525 (dont_register_blocks, bytes_used_when_reconsidered)
6526 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6527 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6528 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6529 Remove. All uses removed.
6530 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6531 implementation, one that depends on whether the new macro
6532 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6534 * atimer.c (run_timers, handle_alarm_signal):
6535 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6536 (handle_async_input, process_pending_signals)
6537 (handle_input_available_signal, init_keyboard):
6538 * nsterm.m (ns_read_socket):
6539 * process.c (wait_reading_process_output):
6540 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6541 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6543 * xterm.c (XTread_socket):
6545 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6546 * eval.c (handling_signal): Remove. All uses removed.
6547 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6548 All uses replaced with the SYNC_INPUT version.
6549 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6551 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6554 * font.c (Ffont_shape_gstring): Remove unused local.
6556 2012-09-16 Glenn Morris <rgm@gnu.org>
6558 * Makefile.in (clean): No longer run nextstep's clean.
6560 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6562 (ns-app): Move here from ns.mk, and simplify.
6563 (clean): Simplify nextstep entry.
6564 * ns.mk: Remove file.
6566 2012-09-17 Kenichi Handa <handa@gnu.org>
6568 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6569 not covert the last few charactes.
6571 2012-09-16 Kenichi Handa <handa@gnu.org>
6573 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6574 here, but just check the validity of glyphs in the glyph-string.
6576 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6578 * window.c (Fwindow_parameter, Fset_window_parameter):
6579 Accept any window as argument (Bug#12452).
6581 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6583 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6584 to ns_term_init to avoid memory leak.
6586 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6587 explicit retain/release.
6588 (ns_term_init): Only allow one display. Initialize outerpool and
6591 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6593 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6594 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6595 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6596 the Microsoft problem in a different way, by altering ../nt/config.nt.
6598 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6613 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6614 by lisp.h. This completes removal of setjmp.h inclusion
6615 erroneously announced in the previous commit. (Bug#12446)
6617 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6620 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6621 not defined as a macro. The latter happens on MS-Windows.
6624 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6626 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6627 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6628 Some instances of '#include <setjmp.h>' removed, if the
6629 only reason for the instance was because "lisp.h" was included.
6630 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6631 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6632 and _longjmp with the new symbols. Emacs already uses _setjmp if
6633 available, so this change affects only POSIXish hosts that have
6634 sigsetjmp but not _setjmp, such as some versions of Solaris and
6635 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6636 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6637 (png_load_body) [HAVE_PNG]:
6638 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6639 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6640 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6641 since PNG requires jmp_buf. This is the only exception to the
6642 general rule that we now use sys_setjmp and sys_longjmp.
6643 This exception is OK since this code does not change the signal
6644 mask or longjmp out of a signal handler.
6646 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6648 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6649 Include "syssignal.h", for 'main_thread'.
6651 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6653 Avoid out-of-range marker position (Bug#12426).
6654 * insdel.c (replace_range, replace_range_2):
6655 Adjust markers before overlays, as suggested by comments.
6656 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6657 Remove redundant check before calling offset_intervals.
6659 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6661 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6662 current buffer (Bug#12387).
6664 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6666 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6668 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6670 Use a more backwards-compatible timer format (Bug#12430).
6671 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6672 vector element, not from the 4th, since PSECS is now at the end.
6673 (Fcurrent_idle_time): Doc fix.
6675 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6677 Function to mark objects and remove killed buffers at once.
6678 * alloc.c (discard_killed_buffers): Rename to ...
6679 (mark_discard_killed buffers) ... new name. Add marking
6680 of remaining objects. Fix comment. Adjust users.
6681 (mark_object): Do not touch frame buffer lists here.
6682 * frame.c (delete_frame): Reset frame buffer lists here.
6684 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6686 Better workaround for GNOME bug when --enable-gcc-warnings.
6687 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6688 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6689 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6691 Simplify SIGIO usage (Bug#12408).
6692 The code that dealt with SIGIO was crufty and confusing, e.g., it
6693 played tricks like "#undef SIGIO" but these tricks were not used
6694 consistently. Simplify mostly by not #undeffing standard symbols,
6695 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6696 or not as we please) rather than "defined SIGIO" (standard symbol
6697 that we probably shouldn't #undef).
6698 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6699 Modules that need it can include it.
6700 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6701 * dispextern.h (ignore_sigio): New decl.
6702 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6703 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6704 * emacs.c (shut_down_emacs):
6705 * keyboard.c (kbd_buffer_store_event_hold):
6706 Use ignore_sigio rather than invoking 'signal' directly.
6707 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6709 (FIONREAD, SIGIO): Do not #undef.
6710 (tty_read_avail_input): Use #error rather than a syntax error.
6711 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6712 for I_PIPE, used by SETUP_SLAVE_PTY.
6713 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6714 * sysdep.c (croak): Remove; no longer needed. This bit of
6715 temporary code, with Fred N. Fish's comment that it's temporary,
6716 has been in Emacs since at least 1992!
6717 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6718 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6719 * syssignal.h (croak): Remove decl.
6720 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6721 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6722 now that we're termios-only.
6723 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6724 * term.c (dissociate_if_controlling_tty): Use #error rather than
6727 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6728 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6729 to work around GNOME bug 683906.
6730 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6731 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6732 This works around GCC bug 54561.
6734 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6736 More fixes for 'volatile' and setjmp/longjmp.
6737 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6738 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6739 (png_load_body) [HAVE_PNG]:
6740 (jpeg_load_body) [HAVE_JPEG]:
6741 New function, with most of the old parent function's body.
6742 (png_load) [HAVE_PNG]:
6743 (jpeg_load) [HAVE_JPEG]:
6744 Invoke the new function, to avoid longjmp munging our locals.
6745 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6746 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6747 longjmp is passed 2, as the C standard doesn't guarantee this.
6748 Instead, store the failure code into mgr->failure_code.
6750 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6752 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6753 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6754 (syms_of_keyboard): Remove support for unread-command-char.
6756 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6758 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6759 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6760 violation. (Bug#12426)
6762 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6764 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6766 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6768 * eval.c: Add `inhibit-debugger'.
6769 (Qinhibit_debugger): New symbol.
6770 (call_debugger): Bind it instead of Qdebug_on_error.
6771 (maybe_call_debugger): Test Vinhibit_debugger.
6772 (syms_of_eval): Define inhibit-debugger.
6773 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6774 (syms_of_xdisp): Remove inhibit-debug-on-message.
6776 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6778 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6779 If a nonvolatile local variable is written before a _longjmp to
6780 the frame containing the variable, and is read after the _longjmp,
6781 the value read is indeterminate. Some local variables of type
6782 'struct handler' and 'struct catchtag' are used in this way, so
6783 mark each of their slots as volatile if the slot can be set before
6784 _longjmp and read afterwards.
6785 * lisp.h (struct handler): var and chosen_clause are now volatile.
6786 (struct catchtag): val, next, and pdlcount are now volatile.
6788 * bidi.c (bidi_push_it, bidi_pop_it):
6789 * fns.c (copy_hash_table):
6790 * image.c (define_image_type):
6791 * keyboard.c (kbd_buffer_store_event_hold):
6792 * process.c (Fprocess_send_eof):
6793 * xfaces.c (x_create_gc) [HAVE_NS]:
6794 * xgselect.c (xg_select):
6795 Prefer assignment to memcpy when either will do.
6797 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6798 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6799 time an item is removed. No need to mark this function 'inline';
6800 the compiler knows better than we do.
6802 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6804 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6805 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6806 to change_frame_size (Bug#12388).
6807 (windowDidResize:): Pass YES to updateFrameSize.
6809 * nsterm.h: Add delay parameter to updateFrameSize.
6811 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6813 Discard killed buffers from deleted window and frame objects.
6814 This reduces an amount of references to killed buffers and
6815 helps GC to reclaim them faster.
6816 * alloc.c (discard_killed_buffers): New function.
6817 (mark_object): Use it for deleted windows and frames.
6818 (mark_object): If symbol's value is set up for a killed buffer
6819 or deleted frame, restore its global binding.
6820 * data.c (swap_in_global_binding): Add GC notice.
6821 (swap_in_symval_forwarding): Use convenient set_blv_where.
6822 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6823 * window.h: ... to here.
6825 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6827 Convenient macro to check whether the buffer is live.
6828 * buffer.h (BUFFER_LIVE_P): New macro.
6829 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6830 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6832 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6834 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6835 composition cases (Bug#12364).
6837 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6838 overhang of succeeding glyphs overlapping box cursor.
6840 * w32term.c (x_draw_glyph_string): Likewise.
6842 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6844 Simplify, document, and port floating-point (Bug#12381).
6845 The porting part of this patch fixes bugs on non-IEEE platforms
6846 with frexp, ldexp, logb.
6847 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6849 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6850 support, by removing commented-out code and briefly listing the
6851 C89 functions excluded. The commented-out stuff was confusing
6852 maintenance, e.g., we thought we needed cbrt but it was commented out.
6853 (logb): Remove decl; no longer needed.
6854 (isfinite): New macro, if not already supplied.
6855 (isnan): Don't replace any existing macro.
6856 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6857 are present on all C89 platforms.
6858 (Ffrexp): Do not special-case zero, as frexp does the right thing
6860 (Flogb): Do not use logb, as it doesn't have the desired meaning
6861 on hosts that use non-base-2 floating point. Instead, stick with
6862 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6863 frexp, to avoid getting an unspecified result.
6865 * xdisp.c (Qinhibit_debug_on_message): Now static.
6867 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6869 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6870 NSBezierPath (Bug#12131).
6872 2012-09-10 Chong Yidong <cyd@gnu.org>
6874 * fns.c (Fdelq, Fdelete): Doc fix.
6876 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6878 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6879 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6881 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6883 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6884 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6887 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6889 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6890 left fringe if the window has a left margin. This avoids leaving
6891 traces of the cursor because its leftmost pixel is not drawn over.
6893 * dispnew.c (update_window_line): When the left margin area of a
6894 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6895 that screen line. (Bug#12277)
6897 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6899 Assume C89 or later for math functions (Bug#12381).
6900 This simplifies the code, and makes it a bit smaller and faster,
6901 and (most important) makes it easier to clean up signal handling
6902 since we can stop worring about floating-point exceptions in
6903 library code. That was a problem before C89, but the problem
6904 went away many years ago on all practical Emacs targets.
6905 * data.c, image.c, lread.c, print.c:
6906 Don't include <math.h>; no longer needed.
6907 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6908 might be autoconfigured, as that never happens.
6910 * doprnt.c (DBL_MAX_10_EXP):
6911 * print.c (DBL_DIG):
6912 Remove. C89 or later always defines these.
6913 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6914 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6915 (arith_error, domain_error, domain_error2):
6916 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6917 no longer needed -- we simply return what C returns. All uses removed.
6918 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6920 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6921 Remove. All uses expanded, as these macros are no longer used
6922 more than once and are now more trouble than they're worth.
6923 (Ftan): Use tan, not sin / cos.
6924 (Flogb): Assume C89 frexp.
6925 (fmod_float): Assume C89 fmod.
6926 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6927 (init_floatfns): Remove. All uses removed.
6929 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6931 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6932 compositeToPoint for OSX < 10.6 (Bug#12390).
6934 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6936 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6937 This produces more-accurate results.
6939 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6941 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6942 changes (Bug#12088).
6944 2012-09-08 Chong Yidong <cyd@gnu.org>
6946 * syntax.c (Fstring_to_syntax): Doc fix.
6948 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6950 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6951 in the internal border.
6952 (x_set_window_size): Remove static variables and their usage.
6953 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6954 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6955 Remove fringe/internal border adjustment (Bug#11052).
6956 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6957 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6958 (ns_fix_rect_ibw): Remove.
6959 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6960 (ns_dumpglyphs_box_or_relief): Ditto.
6961 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6963 (ns_dumpglyphs_image): Ditto.
6964 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6966 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6967 their usage. Add fringe_extended_p and its use as in other terms.
6968 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6969 scroll bar was removed.
6970 (updateFrameSize): New function.
6971 (windowDidResize): Move code to updateFrameSize and call it.
6973 * nsterm.h (EmacsView): Add updateFrameSize.
6975 2012-09-07 Chong Yidong <cyd@gnu.org>
6977 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6979 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6981 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6983 More signal-handler cleanup (Bug#12327).
6984 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6985 Problem introduced when merging patches. Noted by Eli Zaretskii in
6986 <http://bugs.gnu.org/12327#67>.
6987 * floatfns.c: Comment fix.
6988 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6989 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6990 and anyway the declaration is harmless even if SIGDANGER is not defined.
6991 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6992 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6993 source files not surprisingly expected syssignal.h to define, or
6994 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6995 Include <sys/ioctl.h>, for FIONREAD.
6996 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6997 This eliminates a problem whereby other files mysteriously had
6998 to include "syssignal.h" before including "systty.h" if they
6999 wanted to use "#ifdef SIGIO".
7001 2012-09-07 Eli Zaretskii <eliz@gnu.org>
7003 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
7005 * w32.c (sigemptyset): Empty the set.
7006 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
7008 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
7010 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
7012 * alloc.c (mark_buffer): Revert unsafe marking optimization.
7013 (mark_object): Likewise for frame objects.
7015 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
7017 * syssignal.h (handle_on_main_thread): Always declare,
7018 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
7019 This ports to platforms without HAVE_PTHREAD.
7021 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7023 Signal-handler cleanup (Bug#12327).
7024 Emacs's signal handlers were written in the old 4.2BSD style with
7025 sigblock and sigmask and so forth, and this led to some
7026 inefficiencies and confusion. Rewrite these to use
7027 pthread_sigmask etc. without copying signal sets around. Also,
7028 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
7029 'signal', and instead use functions that do not attempt to take
7030 over the system name space. This patch causes Emacs's text
7031 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
7032 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
7033 Do not include <signal.h> or "syssignal.h", as these
7034 modules do not use signals.
7035 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
7036 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
7037 Do not include <signal.h>, as "syssignal.h" does that for us now.
7038 * atimer.c (sigmask_atimers): New function.
7039 (block_atimers, unblock_atimers): New functions,
7040 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
7042 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
7043 no longer needed here.
7044 * emacs.c (main): Inspect existing signal handler with sigaction,
7045 so that there's no need to block and unblock SIGHUP.
7046 * sysdep.c (struct save_signal): New member 'action', replacing
7047 old member 'handler'.
7048 (save_signal_handlers, restore_signal_handlers):
7049 Use sigaction instead of 'signal' to save and restore.
7050 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7051 New function. All users of 'signal' modified to use set_sighandler
7052 if they're writeonly, and to use sys_signal if they're read+write.
7053 (emacs_sigaction_init, forwarded_signal): New functions.
7054 (sys_signal): Remove. All uses replaced by calls to sigaction
7055 and emacs_sigaction_init, or by direct calls to 'signal'.
7056 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7057 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7058 all uses replaced by pthread_sigmask etc. calls.
7059 * syssignal.h: Include <signal.h>.
7060 (emacs_sigaction_init, forwarded_signal): New decls.
7061 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7062 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7063 (sigmask, sys_sigmask): Remove; no longer needed.
7064 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7065 (sigblock, sigunblock, sigfree):
7066 (sigsetmask) [!defined sigsetmask]:
7067 Remove. All uses replaced by pthread_sigmask.
7068 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7069 no longer need to be replaced, and its typical old uses
7070 are now done via emacs_sigaction_init and sigaction.
7071 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7072 (sys_sigdel): Remove; unused.
7073 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7075 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7077 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7078 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7080 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7082 Explicitly mark buffer_defaults and buffer_local_symbols.
7083 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7084 mark_local_symbols here.
7085 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7086 since special buffers aren't marked here any more.
7087 (allocate_buffer): Chain new buffer with all_buffers here...
7088 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7090 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7091 (syms_of_buffer): Remove staticpro of the above.
7092 (init_buffer_once): Set names for buffer_defaults and
7093 buffer_local_symbols.
7095 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7097 Use bool for booleans in font-related modules.
7098 * font.c (font_intern_prop, font_style_to_value)
7099 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7100 (generate_otf_features, font_check_otf_features, font_check_otf)
7101 (font_match_p, font_list_entities, font_at):
7102 * fontset.c (fontset_id_valid_p, reorder_font_vector
7103 (fontset_find_font, Fset_fontset_font)
7104 (face_suitable_for_char_p) [0]:
7105 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7106 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7107 (m17n_flt_initialized, ftfont_shape_by_flt):
7108 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7109 * nsfont.m (nsfont_draw):
7110 * w32font.c (w32font_draw):
7111 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7112 Use bool for booleans.
7113 * font.h: Adjust to above API changes.
7114 (struct font, struct font_driver, struct font_driver_list):
7115 Use bool for booleans.
7116 (struct font): Remove useless member encoding_type.
7118 * fontset.c, xftfont.c: Omit unnecessary static decls.
7120 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7122 * alloc.c (mark_object): Revert window marking code
7123 since it's unsafe for the Fset_window_configuration.
7125 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7127 Fix race conditions with signal handlers and errno (Bug#12327).
7128 Be more systematic about preserving errno whenever a signal
7129 handler returns, even if it's not in the main thread. Do this by
7130 renaming signal handlers to distinguish between signal delivery
7131 and signal handling. All uses changed.
7132 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7133 * data.c (deliver_arith_signal): Rename from arith_error.
7134 * dispnew.c (deliver_window_change_signal): Rename from
7135 window_change_signal.
7136 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7137 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7138 * keyboard.c (deliver_input_available_signal): Rename from
7139 input_available_signal.
7140 (deliver_user_signal): Rename from handle_user_signal.
7141 (deliver_interrupt_signal): Rename from interrupt_signal.
7142 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7143 (deliver_child_signal): Rename from sigchld_handler.
7144 * atimer.c (handle_alarm_signal):
7145 * data.c (handle_arith_signal):
7146 * dispnew.c (handle_window_change_signal):
7147 * emacs.c (handle_fatal_signal, handle_danger_signal):
7148 * keyboard.c (handle_input_available_signal):
7149 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7150 * process.c (handle_pipe_signal, handle_child_signal):
7151 New functions, with the actual signal-handling code taken from the
7152 original respective signal handlers, sans the sporadic attempts to
7153 preserve errno, since that's now done by handle_on_main_thread.
7154 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7155 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7156 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7158 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7159 Move initialization of main_thread to sysdep.c's init_signals.
7160 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7161 our usage, and simplifies the mainline code.
7162 (record_child_status_change): New static function, as a helper
7163 for handle_child_signal, and with most of the old child handler's
7165 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7166 (handle_child_signal): Use the above.
7167 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7168 Moved here from emacs.c.
7169 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7170 code moved here from emacs.c's main function.
7171 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7172 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7173 This lets callers save and restore errno properly.
7175 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7177 Remove redundant or unused things here and there.
7178 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7179 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7180 * editfns.c (Fcompare_buffer_substrings): Likewise.
7181 * frame.h (struct terminal, struct font_driver_list):
7182 Remove redundant declarations.
7183 * window.h (Qleft, Qright): Likewise.
7185 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7187 Do not mark objects from deleted buffers, windows and frames.
7188 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7189 (mark_object): Likewise for windows and frames.
7191 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7193 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7194 buffer_defaults and buffer_local_symbols as valid objects.
7195 Return special value to denote them.
7197 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7199 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7200 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7201 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7202 (file_name_absolute_p, Fsubstitute_in_file_name):
7203 (check_executable, check_writable, Ffile_accessible_directory_p)
7204 (Fset_file_selinux_context, Fdefault_file_modes)
7205 (Finsert_file_contents, choose_write_coding_system)
7206 (Fwrite_region, build_annotations, a_write, e_write)
7208 * filelock.c (boot_time_initialized, get_boot_time)
7209 (get_boot_time_1, lock_file_1, within_one_second):
7210 * floatfns.c (in_float):
7211 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7212 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7213 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7214 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7215 * window.c (compare_window_configurations):
7216 Use bool for booleans.
7217 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7218 (Fdefault_file_modes): Now mode_t, not int, for modes.
7219 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7220 (internal_delete_file): Now returns void, not a (boolean) int,
7221 since nobody was looking at the return value.
7222 * lisp.h, window.h: Adjust to above API changes.
7224 * xdisp.c (set_message): Simplify and reindent last change.
7226 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7228 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7230 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7232 * eval.c (call_debugger): Make the function non-static so that we
7233 can call it from set_message.
7235 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7236 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7238 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7240 Give more-useful info on a fatal error (Bug#12328).
7241 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7242 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7243 of doing the work ourselves.
7244 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7245 do most of the work.
7246 (fatal_error_backtrace): New function, taken from the guts
7247 of the old fatal_error_signal, but with a new option to output
7249 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7250 info about the signal than just its number.
7251 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7252 * sysdep.c: Include <execinfo.h>
7253 (emacs_backtrace): New function, taken partly from the previous
7254 code of the 'die' function.
7255 (emacs_abort): Call fatal_error_backtrace rather than abort.
7257 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7259 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7260 eager (load-time) macro-expansion.
7261 * lisp.mk (lisp): Add macroexp.
7263 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7265 Simplify redefinition of 'abort' (Bug#12316).
7266 Do not try to redefine the 'abort' function. Instead, redo
7267 the code so that it calls 'emacs_abort' rather than 'abort'.
7268 This removes the need for the NO_ABORT configure-time macro
7269 and makes it easier to change the abort code to do a backtrace.
7270 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7271 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7272 Remove; sysdep.c's emacs_abort now takes its place.
7273 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7274 'abort' changed to use 'emacs_abort'.
7275 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7276 (abort) [!defined abort]: Rename to ...
7277 (emacs_abort): ... new name.
7278 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7279 the place of the old 'abort' in emacs.c.
7280 * w32.c, w32fns.c (abort): Do not #undef.
7281 * w32.c (emacs_abort): Rename from w32_abort.
7283 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7285 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7286 offsets[j].dv, since the y axis of the screen coordinates points
7287 down, while the y axis of the font definition coordinates points
7288 up. This fixes display of Arabic diacritics such as KASRA and
7289 KASRATAN. (Bug#11860)
7291 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7293 Be more systematic about _setjmp vs setjmp.
7294 * alloc.c (test_setjmp, mark_stack):
7295 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7296 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7297 (png_load, my_error_exit, jpeg_load):
7298 * process.c (send_process_trap, send_process):
7299 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7300 The underscored versions are up to 30x faster on some hosts.
7301 Formerly, the code used setjmp+longjmp sometimes and
7302 _setjmp+_longjmp at other times, with no particular reason to
7303 prefer setjmp+longjmp.

7340 * msdos.c (fatal_error_in_progress): ... from here.
7341 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead

7344 REDISPLAYING_P when unwinding, instead of saving its previous,
7345 always-false value and then restoring it.
7347 Clean up some extern decls.
7348 Mostly, this hoists extern decls out of .c files and into .h files.
7349 That way, we're more likely to catch errors if the interfaces change.
7350 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
7351 declare xg_mark_data.

7376 * xfaces.c: Remove unnecessary static decls.
7377 * xterm.c (updating_frame): Remove decl of nonexistent object.
7379 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
7380 when building globals.h, as the objects that are not built on
7381 this host are not needed to compile C files on this host.

7435 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
7436 more than one grapheme cluster passed to the shaper: compute the
7437 offset adjustment values separately for each cluster. (Bug#11860)
7439 * image.c: Restore mistakenly removed inclusion of w32.h. Without
7440 it, GCC doesn't see prototypes of w32_delayed_load, and complains
7441 about implicit conversions from integer to pointer.
7443 2012-09-01 Daniel Colascione <dancol@dancol.org>
7445 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7446 system used too early.
7448 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>

7499 window system declarations.
7501 * frame.h: Move common functions here: set_frame_menubar,
7502 x_set_window_size, x_sync, x_get_focus_frame,
7503 x_set_mouse_position, x_set_mouse_pixel_position,
7504 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7565 * lread.c (init_lread): For out-of-tree builds, only add the
7566 source directory's site-lisp dir to the load-path if it exists,
7567 consistent with in-tree builds. (Bug#12302)

7590 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7591 Add window_closed and button_values. Add void as return value for
7592 add(Button|String|Split). addButton takes int instead of Lisp_Object.

7743 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7745 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7747 Fix spare memory change (Bug#12286).
7748 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7749 (valid_lisp_object_p): Likewise.
7751 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7753 * window.c (Fset_window_configuration): Record any window's old
7754 buffer if it's replaced (see Bug#8789). If the new current
7755 buffer doesn't appear in the selected window, go to its old
7758 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7760 Special MEM_TYPE_SPARE to denote reserved memory.
7761 * alloc.c (enum mem_type): New memory type.
7762 (refill_memory_reserve): Use new type for spare memory.
7763 This prevents live_cons_p and live_string_p from incorrect
7764 detection of uninitialized objects from spare memory as live.
7766 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7769 * Makefile.in (.PHONY): versioclean -> versionclean.
7771 Remove unused external symbols.
7772 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7773 * window.c (Qwindow_valid_p, decode_valid_window):
7774 Now static, not extern.
7775 * data.c (Qinterval): Remove; unused.
7776 (syms_of_data): Do not define 'interval'.
7777 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7778 * window.h (decode_valid_window):
7781 * character.c, charset.c, chartab.c: Use bool for booleans.
7782 * character.c (lisp_string_width, string_count_byte8)
7783 (string_escape_byte8):
7784 * charset.c (charset_map_loaded, load_charset_map, read_hex):
7785 (load_charset_map_from_file, map_charset_chars)
7786 (Fdefine_charset_internal, define_charset_internal)
7787 (Fdeclare_equiv_charset, find_charsets_in_text)
7788 (Ffind_charset_region, char_charset, Fiso_charset):
7789 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
7790 (sub_char_table_set, sub_char_table_set_range)
7791 (char_table_set_range, optimize_sub_char_table)
7792 (map_sub_char_table):
7793 Use bool for boolean.
7794 * character.c (str_to_unibyte): Omit last boolean argument; it was
7795 always 0. All callers changed.
7796 * character.h, charset.h: Adjust to match previous changes.
7797 * character.h (char_printable_p): Remove decl of nonexistent function.
7798 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7799 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7800 are all boolean, so make them single-bit bitfields.
7802 * lisp.h (ASET): Remove attempt to detect side effects.
7803 It was meant to be temporary and it often doesn't work,
7804 because when IDX has side effects the behavior of IDX==IDX
7805 is undefined. See Stefan Monnier in
7806 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7808 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7810 * lisp.h (functionp): New function (extracted from Ffunctionp).
7811 (FUNCTIONP): Use it.
7812 * eval.c (Ffunctionp): Use it.
7814 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7816 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7817 as that's faster and simpler than static storage. Don't bother
7818 with the g_main_context_query overhead if g_main_context_pending
7819 says no events are pending.
7820 (gfds, gfds_size): Remove these static vars.
7821 (xgselect_initialize): Remove; no longer needed.
7822 All uses and decls removed.
7824 * emacs.c (fatal_error_signal_hook): Remove.
7825 All uses removed. This leftover from old code was always 0.
7827 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7828 * casefiddle.c (casify_object, casify_region):
7829 * casetab.c (set_case_table):
7830 * category.c, category.h (word_boundary_p):
7831 * category.h (CHAR_HAS_CATEGORY):
7832 Use bool for booleans, instead of int.
7834 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7836 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7838 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7840 On assertion failure, print backtrace if available.
7841 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7842 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7843 * Makefile.in (LIB_EXECINFO): New macro.
7846 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7847 * bytecode.c (exec_byte_code):
7848 * callint.c (check_mark, Fcall_interactively):
7849 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7850 (getenv_internal, sync_process_alive, call_process_exited):
7851 * lisp.h (USE_SAFE_ALLOCA):
7852 Use bool for booleans, instead of int.
7853 * lisp.h, process.h: Adjust prototypes to match above changes.
7854 * callint.c (Fcall_interactively): Don't assume the mark's
7855 offset fits in 'int'.
7857 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7859 * buffer.c, buffer.h: Use bool for boolean.
7860 * buffer.c (reset_buffer_local_variables)
7861 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7862 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7863 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7864 (overlay_touches_p, overlay_strings, Foverlay_put)
7865 (report_overlay_modification, call_overlay_mod_hooks):
7866 (mmap_enlarge, mmap_set_vars):
7867 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7868 Use bool for booleans, instead of int.
7869 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7870 since the 1-or-0 return value is always ignored anyway.
7871 (mmap_initialized_p):
7872 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7873 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7875 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7877 * bidi.c: Use bool for boolean.
7878 This is a bit more readable, and makes the text segment of bidi.o
7879 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7880 Presumably it's faster too.
7881 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7883 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7884 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7885 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7886 (bidi_explicit_dir_char, bidi_level_of_next_char)
7887 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7888 Use bool for booleans, instead of int.
7889 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7890 (bidi_unshelve_cache): Adjust decls to match code.
7892 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7894 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7897 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7899 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7900 * atimer.h: Include <stdbool.h>.
7902 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7904 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7905 compile time tests instead of run time tests on systems that do
7907 (FRAME_MAC_P): Remove leftover from deleted code.
7908 * frame.c (syms_of_frame): Remove leftover from deleted code.
7910 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7912 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7914 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7916 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7917 Otherwise, the compiler complains about (A?B:C) where B is void
7918 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7919 (fontset_add): Return void, for FONTSET_ADD.
7921 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7923 * alloc.c: Use bool for booleans.
7924 (gc_in_progress, abort_on_gc)
7925 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7926 (dont_register_blocks) [GC_MALLOC_CHECK]:
7927 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7928 (check_string_bytes, make_specified_string, memory_full)
7929 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7930 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7931 (mark_stack, valid_pointer_p, make_pure_string)
7932 (Fgarbage_collect, survives_gc_p, gc_sweep):
7933 Use bool for booleans, instead of int.
7934 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7935 Remove unused local.
7936 * alloc.c (PURE_POINTER_P):
7937 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7938 * editfns.c (Fformat):
7939 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7941 * fns.c (sweep_weak_table):
7942 * lisp.h (suppress_checking, push_message, survives_gc_p)
7943 (make_pure_string, gc_in_progress, abort_on_gc):
7944 * lread.c (readchar, read1):
7945 * print.c (Fprin1_to_string):
7946 * xdisp.c (push_message):
7947 Use bool for booleans affected directly or indirectly by
7950 Make recently-introduced setters macros.
7951 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7952 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7953 (set_fontset_default, set_fontset_fallback): Rename from their
7954 upper-case counterparts, and make them functions rather than macros.
7955 This is more consistent with the other recently-introduced setters.
7956 These don't need to be inline, since they're local.
7958 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7960 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7961 the loop (Bug#12247).
7963 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7965 * lisp.h (vcopy): Use memcpy rather than our own loop.
7966 This fixes a performance regression introduced by the recent
7967 addition of vcopy. This means 'vcopy' will need to be modified
7968 for a copying collector, but that's OK. Also, tighten the
7969 checking in the assertion.
7971 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7973 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7974 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7975 non-base glyph for the width of the base character, according to
7976 what x_draw_composite_glyph_string_foreground expects.
7977 Generate WADJUST value according to composition_gstring_width's
7978 expectations, to produce correct width of the composed character.
7979 Reverse the sign of the DU offset produced by ScriptPlace.
7981 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7983 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7985 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7987 Avoid direct writes to contents member of struct Lisp_Vector.
7988 * lisp.h (vcopy): New function to copy data into vector.
7989 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7990 * fns.c (Ffillarray): Use ASET.
7991 * keyboard.c (timer_check_2): Use AREF and ASET.
7992 (append_tool_bar_item, Frecent_keys): Use vcopy.
7993 * lread.c (read_vector): Use ASET.
7994 * msdos.c (Frecent_doskeys): Use vcopy.
7995 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7996 (Finternal_merge_in_global_face): Use ASET and vcopy.
7997 * xfont.c (xfont_list_pattern): Likewise.
7999 2012-08-21 Martin Rudalics <rudalics@gmx.at>
8001 * window.c (Fwindow_point): For the selected window always return
8002 the position of its buffer's point.
8003 (Fset_window_point): For the selected window always go in its
8004 buffer to the specified position.
8006 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
8008 Setter macros for fontsets.
8009 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
8010 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
8011 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
8014 2012-08-20 Glenn Morris <rgm@gnu.org>
8016 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
8017 Don't assume that `ln -f' works.
8019 2012-08-20 Eli Zaretskii <eliz@gnu.org>
8021 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
8022 and later about non-assignments with no effect. See discussion at
8023 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
8026 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8028 Inline setter functions for Lisp_Objects slots of struct specbinding.
8029 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
8032 2012-08-20 Martin Rudalics <rudalics@gmx.at>
8034 * window.c (select_window): Always make selected window's buffer
8037 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8039 Use AREF and ASET for docstrings of category tables.
8040 * category.h (CATEGORY_DOCSTRING): Use AREF.
8041 (SET_CATEGORY_DOCSTRING): Use ASET.
8042 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
8044 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8046 Inline setter functions for hash table members.
8047 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8048 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8049 (set_hash_key_and_value, set_hash_index, set_hash_next)
8050 (set_hash_hash): New functions.
8051 * charset.c, fns.c: Adjust users.
8053 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8055 Inline getter and setter functions for per-buffer values.
8056 * buffer.h (per_buffer_default, set_per_buffer_default)
8057 (per_buffer_value, set_per_buffer_value): New functions.
8058 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8059 * buffer.c, data.c: Adjust users.
8061 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8063 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8065 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8067 Rely on <config.h> + <unistd.h> to declare 'environ',
8068 as gnulib does this if the system doesn't.
8069 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8070 Remove declaration. MS-Windows declares it on stdlib.h which is
8071 included by conf_post.h.
8072 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8073 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8074 * vm-limit.c: Include <unistd.h>, for 'environ'.
8076 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8077 (start_of_data): Remove decl; mem-limits.h provides it.
8079 * xdisp.c (handle_invisible_prop): Make it a bit faster
8080 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8082 2012-08-19 Chong Yidong <cyd@gnu.org>
8084 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8087 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
8089 * .gdbinit: Use call instead of set when calling a function in the
8092 * data.c (set_internal): Don't use set_blv_found.
8093 (Fkill_local_variable): Likewise.
8095 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8097 * nsfont.m (ns_ascii_average_width): Ensure the string
8098 ascii_printable is initialized with a null-terminated character
8099 array. Otherwise, it can contain undesired extra characters.
8101 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8103 port new setting code to Sun C 5.8 2005/10/13
8104 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8105 Return void, not Lisp_Object. Otherwise, the compiler
8106 complains about (A?B:C) where B is void and C is Lisp_Object
8107 when compiling CHAR_TABLE_SET, due to the recent change to
8108 the API of sub_char_table_set_contents.
8110 2012-08-18 Chong Yidong <cyd@gnu.org>
8112 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
8113 for the string case (Bug#3874).
8115 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8117 * buffer.h (BSET): Remove (Bug#12215).
8118 Replace all uses with calls to new setter functions.

8146 * category.c (bset_category_table):
8147 * syntax.c (bset_syntax_table):
8148 New setter functions.
8150 * process.h (PSET): Remove (Bug#12215).
8151 Replace all uses with calls to new setter functions.

8153 (PROCESS_INLINE): New macro.
8154 (pset_childp): New setter function.
8155 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
8156 * process.c (PROCESS_INLINE):
8157 Define to EXTERN_INLINE, so that the corresponding functions
8158 are compiled into code.

8162 (pset_plist, pset_sentinel, pset_status, pset_tty_name)
8163 (pset_type, pset_write_queue): New setter functions.
8165 * window.h (WSET): Remove (Bug#12215).
8166 Replace all uses with calls to new setter functions.
8167 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
8168 (WINDOW_INLINE): New macro.

8172 (wset_window_end_pos, wset_window_end_valid)
8173 (wset_window_end_vpos): New setter functions.

8945 value of EMACSLOADPATH, as it is no longer needed.
8946 (check_windows_init_file): Now external, not static.

8952 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8997 * alloc.c (record_xmalloc): New function.
8998 * lisp.h (record_xmalloc): New decl.
8999 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts

9001 needed. All uses changed.
9002 * print.c (print_string, print_error_message): Avoid length recalc.
9004 Improve fix for macroexp crash with debugging (Bug#12118).
9005 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to

9040 If possible, get file's attributes and security information by
9041 handle, not by name. Produce S_IFLNK bit for symlinks, when
9042 called from 'lstat'.
9043 (stat, lstat): New functions, call 'stat_worker'.
9044 (symlink, readlink, careadlinkat): Rewritten to create and resolve
9045 symlinks when the underlying filesystem supports them.
9047 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9049 Fix macroexp crash on Windows with debugging (Bug#12118).
9050 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9051 checking subscripts; problem introduced with the recent
9052 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.

9512 * .gdbinit (xvectype, xpr, xbacktrace): Adjust to reflect the
9513 2012-07-04 changes to pseudovector representation.
9514 Problem reported by Eli Zaretskii in <http://bugs.gnu.org/12036#30>.
9516 2012-07-27 Michael Albinus <michael.albinus@gmx.de>
9518 * dbusbind.c (XD_DBUS_VALIDATE_BUS_ADDRESS): Canonicalize session
9520 (xd_close_bus, Fdbus_init_bus): Handle reference counter properly.
9522 2012-07-27 Eli Zaretskii <eliz@gnu.org>
9524 * alloc.c (listn): Fix the order the arguments are consed onto the
9527 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9528 enumeration constants, as PURE and HEAP are too general, and clash
9529 with other headers and sources, such as gmalloc.c and the
9530 MS-Windows system headers. All users changed.
9532 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9534 Revert last save_excursion_save and save_excursion_restore changes.
9535 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9545 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
9547 Improve GDB symbol export (Bug#12036).
9548 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9549 arms of an 'if', not using conditional expressions; otherwise GDB
9550 complains about the types in the unevaluated arm when the argument
9551 is an integer literal.
9552 (xgetint): Simplify expression.
9553 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9554 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9555 Zaretskii in <http://bugs.gnu.org/12036#13>.
9556 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9557 needed now that we have gdb_make_enums_visible.
9558 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9559 (enum enum_USE_LSB_TAG):
9560 New enum types, packaging up enums that need to be exported to GDB.
9562 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9564 Utility function to make a list from specified amount of objects.
9565 * lisp.h (enum constype): New datatype.
9566 (listn): New prototype.
9567 * alloc.c (listn): New function.
9568 (Fmemory_use_count, syms_of_alloc): Use it.

9576 * w32.c (init_environment): Likewise.
9577 * w32fns.c (Fw32_battery_status, syms_of_w32fns): Likewise.
9578 * xdisp.c (syms_of_xdisp): Likewise.
9579 * xfns.c (syms_of_xfns): Likewise.
9581 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9583 Fast save_excursion_save and save_excursion_restore.
9584 * lisp.h (struct Lisp_Excursion): New data type.
9585 (PVEC_EXCURSION): New pseudovector type.
9586 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9587 to deal with it. Adjust comments.
9588 (init_marker, attach_marker): New prototype.
9589 (unchain_marker): Adjust prototype.
9590 * marker.c (attach_marker): Change to global.

9595 * editfns.c (save_excursion_save, save_excursion_restore):
9596 Reimplement to use struct Lisp_Excursion. Add comments.
9598 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9600 Fix export of symbols to GDB (Bug#12036).
9601 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9602 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9603 emacs.c, as this is a more-suitable home. Had this been done earlier
9604 the fix for 12036 would have avoided some of the problems noted in
9605 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9606 would have been more obvious.
9607 * emacs.c: Do not include <verify.h>; no longer needed.
9608 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9609 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9610 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9611 Remove; now done in lisp.h.
9612 * lisp.h (PUBLISH_TO_GDB): New macro.
9613 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
9614 (DATA_SEG_BITS): Use it.
9615 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9616 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9617 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9618 not be usable in #if. This simplifies things.
9620 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9622 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9624 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9626 Simplify export of symbols to GDB (Bug#12036).
9627 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9628 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9629 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9630 Adjust to changes in lisp.h and emacs.c, by using
9631 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9632 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9633 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9634 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9635 instead of gdb_valbits.
9636 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9637 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9638 instead of gdb_array_mark_flag.
9639 (xboolvector): Get size from $->size, not $->header.size.
9640 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9641 (xreload, hook-run, hookpost-run): Remove.
9642 * emacs.c: Include <verify.h>.
9643 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9644 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9646 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9647 (gdb_USE_LSB_TAG): New enum constants.
9648 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9649 Also define these as enum constants, so they're visible to GDB.
9650 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9651 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9652 as constants, so they're visible to GDB.
9653 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9654 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9655 Now enum constants, not macros, so they're visible to GDB.
9656 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9657 more convenient now. All uses changed.
9658 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9659 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9661 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
9663 Explicitly free restriction data that are not needed anymore.

9666 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9668 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9669 add argument, tune behavior, and adjust all callers.
9671 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9673 Use typedef for EMACS_INT, EMACS_UINT.
9674 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9675 than macros. This simplifies debugging in the usual case, since
9676 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9677 and it allows expressions involving EMACS_INT casts.
9678 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9680 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
9682 * nsterm.m (ns_read_socket): Return early if there is a modal
9685 2012-07-25 Martin Rudalics <rudalics@gmx.at>

9688 that FOCUS-FRAME can be omitted.
9690 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9692 Adjust buffer text indirection counters at the end of Fkill_buffer.
9693 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9694 buffer is definitely dead. This should really fix an issue reported
9695 by Christoph Scholtes again. (Bug#12007).
9696 (init_buffer_once): Initialize indirection counters of
9697 buffer_defaults and buffer_local_symbols (for sanity and safety).
9699 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9701 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9702 and continuation glyphs on tooltip frames, leave them at zero.
9703 Avoids continued lines in tooltips. (Bug#11832)
9705 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
9707 Simplify copy_overlay.
9708 * buffer.c (copy_overlay): Simplify. Use build_marker.

9714 or invalid. (Bug#12025)
9716 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
9717 it signals an error when a tooltip frame is being created.
9719 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9721 Cleanup miscellaneous objects allocation and initialization.
9722 * alloc.c (allocate_misc): Change to static. Add argument to
9723 specify the subtype. Adjust comment and users.
9724 (build_overlay): New function.
9725 * buffer.c (copy_overlays, Fmake_overlay): Use it.
9726 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.

9728 (build_overlay): Add prototype.
9730 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9732 Swap buffer text indirection counters in Fbuffer_swap_text.
9733 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9734 This avoids crash reported by Christoph Scholtes at
9735 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9737 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9739 * nsmenu.m (Popdown_data): New struct.
9740 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9742 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9743 (initWithContentRect): Make imgView and contentView non-static
9744 and autorelease them. Also autorelease img and matrix (Bug#12005).
9745 (dealloc): Remove (Bug#12005).
9747 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9749 Adjust consing_since_gc when objects are explicitly freed.
9750 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
9751 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.
9752 (free_cons, free_misc): Subtract object size from consing_since_gc.
9754 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9756 Simplify and cleanup markers positioning code.

9758 (live_buffer, set_marker_internal): New function.
9759 (Fset_marker, set_marker_restricted): Use set_marker_internal.
9760 (set_marker_both, set_marker_restricted_both): Use live_buffer.
9762 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9764 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9765 as it's limited by the amount of memory, not by INT_MAX.
9767 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9769 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9770 in special-event-map. See the discussion at
9771 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
9774 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
9775 info.dwItemData. Fixes crashes on 64-bit Windows.

9792 * buffer.h (struct buffer): New member.
9793 * buffer.c (Fget_buffer_create): Set indirection counter to 0.
9794 (Fmake_indirect_buffer): Set indirection counter to -1, increment
9795 base buffer indirection counter.
9796 (compact_buffer): If ENABLE_CHECKING, verify indirection counters.

9829 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
9830 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
9831 Adjust users accordingly.
9832 * font.h (font_open_by_name): Adjust prototype.
9834 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

9843 * bytecode.c (MAYBE_GC): Use maybe_gc.
9844 * eval.c (eval_sub, Ffuncall): Likewise.
9845 * keyboard.c (read_char): Likewise. Adjust call to maybe_gc
9846 to avoid dependency from auto-save feature.
9848 2012-07-19 Paul Eggert <eggert@cs.ucla.edu>
9850 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
9851 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
9852 'for_each_per_buffer_object_at'.
9853 All uses changed. It's better to use upper-case for macros that
9854 cannot be implemented as functions, to give the reader a clue
9855 that they're special.
9857 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
9859 * alloc.c (Fgarbage_collect): Tweak docstring.

9899 Fix bug that created negative-length intervals.
9900 * intervals.c (merge_interval_right, merge_interval_left):
9901 Do not zero out this interval if it is absorbed by its children,
9902 as this interval's total length doesn't change in that case. See
9903 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
9905 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
9907 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
9908 when invoking (make-bool-vector N t) and N is a positive
9909 multiple of 8 -- the last 8 bits were mistakenly cleared.
9911 Remove some struct layout assumptions in bool vectors.
9912 * alloc.c (bool_header_size): New constant.
9913 (header_size, word_size): Move earlier, as they're now used earlier.
9914 Use 'word_size' in a few more places, where it's appropriate.
9915 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
9916 padding before the data member of a bool vector.
9917 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
9918 than doing the check by hand with an abort ().
9920 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9922 * eval.c (Fdefvar): Don't check constants since we only set the var if
9923 it's not yet defined anyway (bug#11904).
9925 * lisp.h (last_undo_boundary): Declare new var.
9926 * keyboard.c (command_loop_1): Set it.
9927 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
9928 were auto-added by the command loop (bug#11774).
9930 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
9932 * w32font.c (Qsymbol): Remove local definition.

10421 2012-07-11 Glenn Morris <rgm@gnu.org>
10423 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
10424 since nothing has defined it on these platforms.
10426 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
10427 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

10436 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
10438 2012-07-11 John Wiegley <johnw@newartisans.com>
10440 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
10441 function attribute, so we only use it if it exists in the
10444 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10446 Avoid call to strlen in fast_c_string_match_ignore_case.
10447 * search.c (fast_c_string_match_ignore_case): Change to use
10448 length argument. Adjust users accordingly.
10449 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
10451 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

10468 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10470 Avoid calls to strlen in font processing functions.
10471 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
10472 (font_open_by_name): Change to use length argument.

10490 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
10492 Remove "#define unix" that is no longer needed (Bug#11905).
10493 * s/aix4-2.h (unix): Remove; no longer needed.
10495 EMACS_TIME simplification (Bug#11875).
10496 This replaces macros (which typically do not work in GDB)
10497 with functions, typedefs and enums, making the code easier to debug.
10498 The functional style also makes code easier to read and maintain.
10499 * systime.h: Include <sys/time.h> on all hosts, not just if
10500 WINDOWSNT, since 'struct timeval' is needed in general.
10501 (EMACS_TIME): Now a typedef, not a macro.
10502 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
10504 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
10505 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

10509 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
10510 which are not functions. All uses rewritten to use:
10511 (make_emacs_time): New function.
10512 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
10513 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
10514 not functions. All uses rewritten to use the following, respectively:
10515 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
10516 (add_emacs_time, sub_emacs_time): New functions.
10517 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
10518 * fileio.c (Fcopy_file):
10519 * xterm.c (XTflash): Get the current time closer to when it's used.
10520 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

10525 * doc.c (Fsnarf_documentation):
10526 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
10527 * frame.c (Fmake_terminal_frame):
10528 * gtkutil.c (get_utf8_string):
10530 * nsmenu.m (ns_update_menubar):
10531 * regex.c (regerror):
10532 Prefer memcpy to strncpy and strncat when either will do.
10533 * fileio.c (Fsubstitute_in_file_name):
10534 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
10535 (menu_separator_name_p):
10536 * nsmenu.m (ns_update_menubar):
10537 Prefer memcmp to strncmp when either will do.
10538 * nsterm.m: Include <ftoastr.h>.
10540 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10541 Prefer snprintf to strncpy.
10542 * nsterm.m (ns_term_init):
10543 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10544 * nsterm.m (ns_term_init):
10545 Avoid the need for strncpy, by using build_string or
10546 make_unibyte_string directly. Use dtoastr, not snprintf.
10547 * process.c (Fmake_network_process): Diagnose service names that
10548 are too long, rather than silently truncating them or creating
10549 non-null-terminated names.
10550 (Fnetwork_interface_info): Likewise, for interface names.
10551 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10552 Prefer sprintf to strncat.
10553 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10554 Prefer vsnprintf to vsprintf + strncpy.
10556 2012-07-10 Glenn Morris <rgm@gnu.org>
10558 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
10559 Clarify fallback case.
10561 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10563 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10564 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10565 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10566 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10567 where argument type is known to be a Lisp_Cons.
10569 2012-07-10 Tom Tromey <tromey@redhat.com>
10571 * bytecode.c (BYTE_CODE_THREADED): New macro.
10572 (BYTE_CODES): New macro. Replaces all old byte-code defines.
10573 (enum byte_code_op): New type.
10574 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
10575 (exec_byte_code): Use them. Use token threading when applicable.
10577 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10579 Optimize pure C strings initialization.
10580 * lisp.h (make_pure_string): Fix prototype.
10581 (build_pure_c_string): New function, defined as static inline. This
10582 provides a better opportunity to optimize away calls to strlen when
10583 the function is called with compile-time constant argument.
10584 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10585 argument, adjust users accordingly. Use build_pure_c_string where
10587 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10588 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10589 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10591 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10593 Avoid calls to strlen in miscellaneous functions.
10594 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10595 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10596 * lread.c (openp): Likewise.
10598 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10600 Avoid calls to strlen in path processing functions.
10601 * fileio.c (file_name_as_directory): Add comment. Change to add
10602 srclen argument and return the length of result. Adjust users
10604 (directory_file_name): Fix comment. Change to add srclen argument,
10605 swap 1st and 2nd arguments to obey the common convention.
10606 Adjust users accordingly.
10607 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10609 2012-07-10 Glenn Morris <rgm@gnu.org>
10611 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
10612 Move PENDING_OUTPUT_COUNT definition to configure.
10614 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10615 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10616 * s/gnu.h (DATA_START): Move definitions to configure.
10618 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10619 We include usg5-4-common.h, which defines them both.
10621 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10622 O_RDONLY already includes it).
10624 Stop ns builds setting the EMACSLOADPATH environment variable.
10625 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10626 Now it does not set EMACSLOADPATH, just returns the load-path string.
10627 * nsterm.h: Update accordingly.
10628 * lread.c [HAVE_NS]: Include nsterm.h.
10629 (init_lread) [HAVE_NS]: Use ns_load_path.
10630 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10632 2012-07-09 Glenn Morris <rgm@gnu.org>
10634 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10635 since the included bsd-common.h does so.
10637 Stop ns builds setting the EMACSPATH environment variable.
10638 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10639 (ns_init_paths): Do not set EMACSPATH.
10640 * nsterm.h (ns_exec_path): Add it.
10641 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10644 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10646 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10648 * process.c (wait_reading_process_output): 'waitchannels' was unset
10649 when read_kbd || !NILP (wait_for_cell); fix this.
10651 Add GCC-style 'const' attribute to functions that can use it.
10652 * character.h (char_resolve_modifier_mask):
10653 * keyboard.h (make_ctrl_char):
10654 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10655 (init_character_once, next_almost_prime, init_fns, init_image)
10656 (flush_pending_output, init_sound):
10657 * mem-limits.h (start_of_data):
10658 * menu.h (finish_menu_items):
10659 Add ATTRIBUTE_CONST.
10660 * emacs.c (DEFINE_DUMMY_FUNCTION):
10661 Declare the dummy function with ATTRIBUTE_CONST.
10662 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
10663 Add decls with ATTRIBUTE_CONST.
10665 Minor improvements to make_formatted_string.
10666 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10667 where int is good enough, as vsprintf returns an int.
10668 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10670 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10672 Use make_formatted_string to avoid double length calculation.
10673 * lisp.h (make_formatted_string): New prototype.
10674 * alloc.c (make_formatted_string): New function.
10675 * buffer.c (Fgenerate_new_buffer_name): Use it.
10676 * dbusbind.c (syms_of_dbusbind): Likewise.
10677 * editfns.c (Fcurrent_time_zone): Likewise.
10678 * filelock.c (get_boot_time): Likewise.
10679 * frame.c (make_terminal_frame, set_term_frame_name)
10680 (x_report_frame_params): Likewise.
10681 * image.c (gs_load): Likewise.
10682 * minibuf.c (get_minibuffer): Likewise.
10683 * msdos.c (dos_set_window_size): Likewise.
10684 * process.c (make_process): Likewise.
10685 * xdisp.c (ensure_echo_area_buffers): Likewise.
10686 * xsettings.c (apply_xft_settings): Likewise.
10688 2012-07-09 Glenn Morris <rgm@gnu.org>
10690 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10691 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10692 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10694 * callproc.c [HAVE_NS]: Include nsterm.h.
10695 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10697 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10699 Move marker debugging code under MARKER_DEBUG.
10700 * marker.c (MARKER_DEBUG): Move marker debugging code under
10701 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10702 for bootstrap with --enable-checking (~3x slowdown reported
10703 by Juanma Barranquero <lekktu@gmail.com>).
10704 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10706 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10708 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10709 See <http://bugs.gnu.org/11825#29>.
10711 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10713 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10714 has no font, use the frame's font. (Bug#11813)
10715 (display_line): Add commentary about displaying truncation glyphs
10717 (produce_special_glyphs): Move here from term.c.
10719 * term.c (produce_special_glyphs): Move to xdisp.c.
10721 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10724 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10726 * xdisp.c (display_line): Avoid warning about implicit declaration
10729 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10731 * lisp.h: Remove empty conditional.
10733 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10735 * lread.c (load_path_check): Now static.
10737 Fix some minor --with-ns problems found by static checking.
10738 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10739 (x_set_font) [!HAVE_X_WINDOWS]:
10740 * image.c (xpm_load_image) [HAVE_NS]:
10741 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10742 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10743 Remove unused local.
10744 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10745 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10746 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10747 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10748 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10749 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10750 Fix pointer signedness problem.
10751 * xfaces.c (FRAME_X_FONT_TABLE):
10752 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10754 2012-07-07 Glenn Morris <rgm@gnu.org>
10756 * lread.c (load_path_check): New function, split from init_lread.
10757 (init_lread): Reorganize. Motivation:
10758 If EMACSLOADPATH is set, check/warn about that rather than the
10759 defaults, which we are not going to use. Hence we can remove
10760 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10761 Don't warn if site-lisp directories are missing.
10762 If not installed, start from a blank load-path, since
10763 PATH_LOADSEARCH refers to the eventual installation directories.
10765 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10767 Support truncation and continuation glyphs on GUI frames, when
10768 fringes are disabled. (Bug#11832)
10769 * xdisp.c (init_iterator): Get dimensions of truncation and
10770 continuation glyphs even if on GUI frames.
10771 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10772 or both, are absent.
10773 (start_display, move_it_in_display_line_to): Handle the case of a
10774 GUI frame without a fringe to display continuation or truncation
10776 (insert_left_trunc_glyphs): Support GUI frames: make sure
10777 truncation glyphs overwrite enough glyphs from the current line to
10778 have sufficient space in pixels.
10779 (display_line): Support truncation and continuation glyphs on GUI
10780 frames. If some spare pixels are left on the line after inserting
10781 the truncation glyphs, fill that space with a stretch glyph of a
10782 suitably computed width.
10784 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10785 produce_glyphs, to support GUI sessions.
10787 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10789 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10791 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10793 Do not require float-time's arg to fit in time_t (Bug#11825).
10794 This works better on hosts where time_t is unsigned, and where
10795 float-time is applied to the (negative) difference between two times.
10796 * editfns.c (decode_time_components): Last arg is now double *,
10797 not int *, and means to store all the result as a double, without
10798 worrying about whether the seconds part fits in time_t.
10799 All callers changed.
10800 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10801 All callers changed.
10802 (Ffloat_time): Do not fail merely because the specified time falls
10803 outside of time_t range.
10805 2012-07-07 Glenn Morris <rgm@gnu.org>

10838 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10839 Eli Zaretskii <eliz@gnu.org>
10841 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10842 Windows-specific code from nt/config.nt moved here.
10843 Obsolete settings removed.
10845 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10847 * process.c: Avoid unnecessary calls to gettime.
10848 (wait_reading_process_output): Don't get the time of day
10849 when gobbling data immediately and not waiting, as there's no need
10850 for it in that case. This removes a FIXME.
10852 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10854 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10855 is defined (Bug#11768).

10861 if buffer is not multibyte.
10862 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10863 Call byte_char_debug_check with correct arguments.
10865 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10867 Compile marker debugging code only if ENABLE_CHECKING is defined.
10868 * marker.c (byte_char_debug_check, count_markers):
10869 Use only if ENABLE_CHECKING is defined.
10870 (byte_debug_flag): Remove.
10871 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10872 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

10902 * window.c (save_window_save): Likewise.
10904 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10906 Do not use Fdelete_overlay in delete_all_overlays
10907 to avoid redundant calls to unchain_overlay.
10908 * buffer.c (drop_overlay): New function.
10909 (delete_all_overlays, Fdelete_overlay): Use it.
10910 * minibuf.c (get_minibuffer): Fix comment.
10912 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10914 Port to OpenBSD 5.1 amd64.
10915 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10916 This is needed for OpenBSD, and should be harmless on all BSD systems.
10917 Also, include <sys/sysctl.h>, as it should be available on all
10918 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10919 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10920 use p_pid member, not kp_proc.pid.
10922 2012-07-06 Glenn Morris <rgm@gnu.org>
10924 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10926 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10928 More xmalloc and related cleanup.

10937 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10939 Omit needless casts involving void * pointers and allocation.
10940 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10941 as the former is more robust if P's type is changed.
10942 Prefer xzalloc to xmalloc + memset 0.
10943 Simplify malloc-or-realloc to realloc.
10944 Don't worry about xmalloc returning a null pointer.
10945 Prefer xstrdup to xmalloc + strcpy.
10946 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10948 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10949 alloca of a constant.

10953 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10954 hscroll is larger than the line width. Fixes long and futile
10955 looping inside extend_face_to_end_of_line (on a TTY) producing
10956 glyphs that are not needed and thrown away.
10958 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10960 * marker.c (set_marker_restricted_both): Simplify by using
10963 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10965 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10974 followed by gtk_box_set_homogeneous (Bug#11768).
10975 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10976 (update_theme_scrollbar_width, xg_create_scroll_bar):
10977 Use gtk_scrollbar_new (Bug#11768).

10979 (is_box_type): New function (Bug#11768).
10980 (xg_tool_item_stale_p): Call is_box_type.
10981 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10982 with default display (Bug#11768).
10984 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10986 * xdisp.c (window_hscroll_limited): New function.
10987 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10988 coordinates when window's hscroll is set to insanely large
10989 values. (Bug#11857)
10991 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11055 Problem reported by Troels Nielsen in
11056 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11058 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11060 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11061 This should be fixed in a better way; see Eli Zaretskii in
11062 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11063 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11065 * fileio.c (time_error_value): Rename from special_mtime.
11066 The old name's problems were noted by Eli Zaretskii in
11067 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11069 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11070 This variable's comment says Emacs needs at least one GDB-visible
11071 symbol of type enum pvec_type, to work around GDB problems.
11072 The symbol's value doesn't matter.
11074 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11075 that causes compilation to fail on pre-C99 compilers.
11077 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11079 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

11103 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11104 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11105 abusing vector->header.next.nbytes.
11106 (live_vector_p): Use PVEC_TYPE.
11107 (mark_object): Adapt code to extract pvectype. Use switch.
11109 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>

11116 Fix compilation with --enable-gcc-warnings and -O1
11117 optimization level.

11119 to avoid compiler warning. Add eassert.
11120 * search.c (simple_search): Initialize match_byte to avoid
11121 compiler warning. Add eassert.
11123 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11125 Avoid weird behavior with large horizontal scrolls.
11126 Without this change, for example, large hscroll values would
11127 mess up Emacs's display on Fedora 15 x86, presumably due to
11128 overflows in int calculations in the display code.
11129 Also, if buffers had long lines, Emacs would freeze.
11130 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11131 (set_window_hscroll): New function, containing the old guts of
11132 Fset_window_hscroll. Return the clipped value.
11133 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11134 This avoids the need to check against PTRDIFF_MAX.
11136 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11138 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

11142 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11144 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11145 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11146 since GCC 4.4.6 issues a bogus warning for them.
11148 Fix bugs in file timestamp newness comparisons.
11149 * fileio.c (Ffile_newer_than_file_p):
11150 * lread.c (Fload): Use full timestamp resolution of files,
11151 not just the 1-second resolution, so that files that are only
11152 slightly newer still count as newer.
11153 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11154 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11156 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11158 * fileio.c: Improve handling of file time marker. (Bug#11852)

11168 2012-07-03 Glenn Morris <rgm@gnu.org>
11170 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11171 and did not make it into globals.h).
11173 2012-07-03 Tom Tromey <tromey@redhat.com>

11231 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11233 * alloc.c (allocate_vector_block): Remove redundant
11234 calls to mallopt if DOUG_LEA_MALLOC is defined.
11235 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11236 avoid calls to mallopt if zero_vector is returned.
11238 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11240 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11241 is enabled, avoid dereferencing NULL current_sblock if
11244 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11246 Cleanup basic buffer management.
11247 * buffer.h (struct buffer): Change layout to use generic vector
11248 marking code. Fix some comments. Change type of 'clip_changed'
11249 to bitfield. Remove unused #ifndef old.
11250 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11251 (GET_OVERLAYS_AT): Fix indentation.
11252 (for_each_per_buffer_object_at): New macro.
11253 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
11254 (Fbuffer_local_variables): Use it.
11255 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
11256 * alloc.c (allocate_buffer): Adjust to match new layout of
11257 struct buffer. Fix comment.
11258 (mark_overlay): New function.
11259 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11260 Lisp area of struct buffer.
11261 (mark_object): Use it. Adjust marking of misc objects
11262 and related comments.
11264 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11266 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11267 wrapper that is not needed because the wrapped code is a no-op (zero
11268 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11269 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11271 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11273 * alloc.c (mark_buffer): Simplify. Remove prototype.
11274 (mark_object): Add comment. Reorganize marking of vector-like
11275 objects. Use CHECK_LIVE for all vector-like objects except buffers
11276 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11277 Avoid redundant calls to mark_vectorlike for bool vectors.
11279 2012-06-30 Glenn Morris <rgm@gnu.org>
11281 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11283 * epaths.in (PATH_SITELOADSEARCH): New.
11284 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11285 This is rather than relying on --enable-locallisppath elements
11286 having "site-lisp" in their names. (Bug#10208#25, 11658)
11288 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11290 * w32proc.c (sys_select): Accept and ignore one more argument.
11292 * w32.c (emacs_gnutls_pull): Call select with one more argument.
11294 * sysselect.h [DOS_NT]: Don't include sys/select.h.
11295 (pselect) [!MS_DOS]: Redirect to sys_select.
11297 * sysdep.c: Don't include dos.h and dosfns.h.
11299 * process.c (sys_select):
11300 * msdos.c (sys_select): Accept one more argument and ignore it.
11302 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11303 adapt data types and code to that.
11306 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11307 which clashes with the gnulib function of the same name.
11309 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11311 * font.c (font_style_to_value, font_style_symbolic)
11312 (font_prop_validate_style): Add type checks for values in
11315 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11317 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11320 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11322 * xdisp.c (try_window_id): Undo last change.
11324 * w32.c (getwd): Adjust commentary about startup_dir.
11325 (init_environment): Always call sys_access, even in non-MSVC
11326 builds. Don't chdir to the directory of the Emacs executable.
11327 This undoes code from 1997 which was justified by the need to
11328 "avoid conflicts when removing and renaming directories". But its
11329 downside was that every relative file name was being interpreted
11330 relative to the directory of the Emacs executable, which can never
11331 be TRT. In particular, it broke sys_access when called with
11332 relative file names.
11333 (sys_access): Map GetLastError to errno.
11335 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11341 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
11344 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
11346 * gnutls.c (emacs_gnutls_handshake):
11347 Add QUIT to make the loop interruptible.
11349 2012-06-29 Glenn Morris <rgm@gnu.org>
11351 * charset.c (init_charset): Make lack of etc/charsets fatal.
11353 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11359 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
11360 undefined. Convert from xassert to eassert.

11362 * nsterm.m: Likewise.
11364 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

11368 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
11370 Avoid integer overflow on scroll-left and scroll-right.
11371 * window.c (HSCROLL_MAX): New macro.
11372 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
11373 overflow when requested scroll falls outside ptrdiff_t range.
11375 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
11377 * window.h (struct window): Change type of 'hscroll',
11378 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11379 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11380 Adjust users accordingly.
11381 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11382 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11383 from EMACS_INT to ptrdiff_t.
11384 (make_window): Omit redundant initialization.

11403 Fix GLYPH_DEBUG usage assuming that it may be undefined,
11404 adjust comments accordingly.

11453 * alloc.c (allocate_string_data): Remove dead code.
11454 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to

11517 * alloc.c: Remove build_string.

11525 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11527 Use sprintf return value instead of invoking strlen on result.
11528 In the old days this wasn't portable, since some sprintf
11529 implementations returned char *. But they died out years ago and
11530 Emacs already assumes sprintf returns int.
11531 Similarly for float_to_string.
11532 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11538 * xdisp.c (message_dolog):
11539 * xfns.c (syms_of_xfns):
11540 Use sprintf or float_to_string result to avoid need to call strlen.
11541 * data.c (Fnumber_to_string):
11542 Use make_unibyte_string, since the string must be ASCII.
11543 * lisp.h, print.c (float_to_string): Now returns int length.
11544 * term.c (produce_glyphless_glyph):
11545 Use sprintf result rather than recomputing it.
11547 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11548 * Makefile.in (ALL_CFLAGS):
11549 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

11554 * dispextern.h (xstrcasecmp): Define to library function
11555 strcasecmp if available.

11574 sprintf already null-terminates its output.
11576 * xfns.c (x_window): Remove redundant cast.
11578 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11580 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11581 `const char *' to `char *' to avoid compiler warning.
11583 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11585 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11586 instead of truncating it to 63 (admittedly a generous limit).
11588 * process.c: Fix spelling and caps in comments.
11590 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11592 * emacs.c (setpgrp): Remove definition, unused.

11639 Remove unnecessary forward decls.
11641 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11643 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).

11645 * dispnew.c (Fsleep_for, sit_for):
11646 * keyboard.c (kbd_buffer_get_event):
11647 * process.c (Faccept_process_output):
11648 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11649 This improves on the previous patch, which introduced a bug
11650 when time_t is unsigned and as wide as intmax_t.
11651 See <http://bugs.gnu.org/9000#51>.
11653 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11671 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
11673 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

11681 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
11682 language ID in the event parameters.
11684 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11685 event.code, not the obscure "character set ID".

11703 in the logic of incrementing and decrementing the value of
11704 use_relocatable_buffers.

11718 Support higher-resolution time stamps (Bug#9000).
11719 The time stamps are only nanosecond-resolution at the C level,
11720 since that's the best that any real-world system supports now.
11721 But they are picosecond-resolution at the Lisp level, as that's
11722 easy, and leaves room for future OS improvements.

11731 now provides it if it's absent.
11732 (start_atimer): Port to higher-res time stamps.
11733 Check for time stamp overflow. Don't get current time more
11734 often than is needed.

11787 (timer_check_2): Use it.
11789 * nsterm.m (select_timeout, timeval_subtract): Remove.
11790 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,

11794 * nsterm.h (ns_select): Adjust prototype.

11815 (select_wrapper): Remove; we now use pselect.
11816 (Fprocess_attributes): Now generates ns-resolution time stamps.
11818 * sysdep.c: Include utimens.h. Don't include utime.h
11819 or worry about struct utimbuf; gnulib does that for us now.
11820 (gettimeofday): Remove; gnulib provides a substitute.
11821 (make_timeval): New function.
11822 (set_file_times): Now sets ns-resolution time stamps.
11823 New arg FD; all uses changed.

11830 provides a substitute now.
11832 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11833 since it guarantees struct timespec.
11834 (EMACS_TIME): Now struct timespec, so that we can support
11835 ns-resolution time stamps.
11836 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11837 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11838 (EMACS_USECS): Remove.
11839 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11840 so multiply the arg by 1000 before storing it.

11850 (make_timeval, make_lisp_time, decode_time_components): New decls.
11851 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

11853 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11854 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

11882 (timeval_subtract): Remove; no longer needed.
11883 (XTflash, XTring_bell, x_wait_for_event):

11893 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11894 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11895 staticidx goes up to 1597 out of 1600 = 0x640.)
11897 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11899 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

11945 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11946 gets killed during executing of this function (Bug#11665).

11973 * lisp.h (eassert): Assume C89 or later.
11974 This removes the need for CHECK.
11975 (CHECK): Remove. Its comments about always evaluating its

12163 -DUSE_LSB_TAG=0, to override the automatically-selected default.
12164 USE_LSB_TAG now is always defined to be either 0 or 1.
12166 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
12167 code works fine either way, and efficiency is not a concern here,
12168 as the union type is for debugging, not for production.
12169 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12170 Use an inline function on all platforms when using the union type,
12171 since this is simpler and 'static inline' can be used portably
12173 (LISP_INITIALLY_ZERO): New macro.
12174 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
12175 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

12202 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
12203 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
12204 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
12206 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
12208 * alloc.c (make_byte_code): New function.

12264 * dispnew.c (showing_window_margins_p): Undo last change, which
12265 was done due to an inadvertent commit.
12266 (adjust_frame_glyphs_for_frame_redisplay): Do call

12275 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
12277 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
12278 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
12280 2012-06-08 Eli Zaretskii <eliz@gnu.org>
12282 * alloc.c (allocate_vectorlike): Fix last change.
12284 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
12286 Block-based vector allocation of small vectors.
12287 * lisp.h (struct vectorlike_header): New field `nbytes',
12288 adjust comment accordingly.
12289 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
12290 to denote vector blocks. Adjust users (live_vector_p,

12313 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
12315 * doprnt.c (doprnt): Truncate multibyte char correctly.
12316 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12317 would mishandle a string argument "Xc" if X was a multibyte
12318 character of length 2: it would truncate after X's first byte
12319 rather than including all of X.
12321 2012-06-06 Chong Yidong <cyd@gnu.org>
12323 * buffer.c (word_wrap): Doc fix.
12325 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

12370 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12372 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12373 Convert pctcpu and pctmem to Lisp float properly.
12374 Let the compiler fold better, as 100.0/0x8000 is exact.
12376 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12378 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12381 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

12385 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12387 For a 'struct window', replace some Lisp_Object fields to
12388 bitfields where appropriate, remove unused fields.
12389 * window.h (struct window): Remove unused 'last_mark_x' and
12390 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12391 change its type from Lisp_Object to bitfield.
12392 Change type of 'force_start', 'optional_new_start',
12393 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
12394 fields from Lisp_Object to bitfield. Adjust users accordingly.
12396 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12398 Pacify gcc -Wdouble-precision when using Xaw.
12399 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12400 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12401 Use 'float' consistently, rather than 'float' in most places
12402 and 'double' in a couple of places.
12404 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12406 * xdisp.c (handle_stop): Detect whether we have overlay strings
12407 loaded by testing it->current.overlay_string_index to be
12408 non-negative, instead of checking whether n_overlay_strings is
12409 positive. (Bug#11587)
12411 2012-05-31 Chong Yidong <cyd@gnu.org>
12413 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12417 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12419 * search.c (search_buffer): Remove calls to
12420 r_alloc_inhibit_buffer_relocation, as it is now called by
12421 maybe_unify_char, which was the cause of relocation of buffer text
12424 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12426 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12427 for the duration of call to load_charset, to avoid problems with
12428 callers of maybe_unify_char that access buffer text through C
12431 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12432 decrement the inhibition flag, instead of just setting or
12435 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12437 Remove obsolete '#define static' cruft.
12438 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12439 This #undef was "temporary" in 2000; it is no longer needed
12440 now that '#define static' has gone away.
12441 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12442 (gray_bitmap_bits): Remove; no longer needed.
12443 All uses replaced with definiens.

12449 The following changes affect the code only when profiling.
12450 * dispnew.c (__executable_start): Rename from safe_bcopy.
12451 Define only on platforms that need it.
12452 * emacs.c: Include <sys/gmon.h> when profiling.
12453 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12454 (__executable_start): Remove decl, since lisp.h does it now.
12455 (safe_bcopy): Remove decl; no longer has that name.
12456 (main): Coalesce #if into single bit of code, for simplicity.
12457 Cast pointers to uintptr_t, since standard libraries want integers
12459 * lisp.h (__executable_start): New decl.
12461 2012-05-31 Glenn Morris <rgm@gnu.org>
12463 * image.c (Fimagemagick_types): Doc fix.

12484 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
12486 Do not create empty overlays with the evaporate property (Bug#9642).
12487 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12488 Bug#9642, but explicitly check that the buffer the overlay would
12489 be moved to is live and rearrange lines to make sure that errors
12490 will not put the overlay in an inconsistent state.
12491 (Fdelete_overlay): Cosmetics.
12493 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12495 * w32term.c (my_bring_window_to_top): New function.
12496 (x_raise_frame): Use handle returned by DeferWindowPos, which
12497 could be different from the original one.

12507 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12509 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12510 This avoids undefined behavior that might cause the eassert
12511 to not catch an out-of-range value.
12513 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12515 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

12527 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12529 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12530 Only r_alloc_inhibit_buffer_relocation needed to be added;
12531 the others were already declared.
12533 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12534 before checking whether it's out of range. Put the check inside
12536 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12538 2012-05-27 Ken Brown <kbrown@cornell.edu>
12540 * callproc.c (Fcall_process): Restore a line that was accidentally
12541 commented out in the 2011-02-13 change (bug#11547).

12545 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12546 defined on ralloc.c.
12548 * buffer.c [REL_ALLOC]: Remove prototypes of
12549 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12550 they are now on lisp.h.
12552 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12554 * search.c (search_buffer): Use it to inhibit relocation of buffer
12555 text while re_search_2 is doing its job, because re_search_2 is
12556 passed C pointers to buffer text. (Bug#11519)
12558 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12559 Update value to 24.
12561 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12562 state after an additional call to move_it_in_display_line_to, keep
12563 the values of it->max_ascent and it->max_descent found for the
12565 (pos_visible_p): Revert the comparison against bottom_y to what it
12566 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12569 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12571 Fix coding-related core dumps with gcc -ftrapv.
12572 The code was computing A - B, where A and B are pointers, and B is
12573 random garbage. This can lead to core dumps on platforms that
12574 have special pointer registers, and it also leads to core dumps on
12575 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12576 A - B only when B is initialized properly.
12577 * coding.c (coding_set_source, coding_set_destination): Return void.
12578 (coding_change_source, coding_change_destinations): New functions,
12579 with the old behaviors of coding_set_source and coding_set_destination.
12580 All callers that need an offset changed to use these new functions.

12590 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12592 * w32console.c: Include window.h.
12593 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12595 (initialize_w32_display): Initialize mouse-highlight data.
12597 * w32inevt.c: Include termchar.h and window.h.
12598 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12599 moves, call note_mouse_highlight. If help_echo changed, call
12600 gen_help_event to produce help-echo message in the echo area.
12601 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12604 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12606 * lread.c (read1): Simplify slightly to avoid an overflow warning
12607 with GCC 4.7.0 on x86-64.
12609 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12611 * bidi.c (bidi_mirror_char): Revert last change: an int is
12612 definitely wide enough here.
12614 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12616 Fix integer width and related bugs (Bug#9874).
12617 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
12618 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
12619 (string_bytes, check_sblock, allocate_string_data):
12620 (compact_small_strings, Fmake_bool_vector, make_string)
12621 (make_unibyte_string, make_multibyte_string)

12650 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12651 (validate_region): Omit unnecessary test for b <= e,
12652 since that's guaranteed by the previous test.
12653 (adjust_overlays_for_delete): Avoid pos + length overflow.
12654 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12655 (report_overlay_modification):
12656 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12657 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12658 Omit pointer cast, which isn't needed anyway, and doesn't work
12659 after the EMACS_INT -> ptrdiff_t change.
12660 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12661 * buffer.h: Adjust decls to match defn changes elsewhere.

12666 not int, to avoid needless 32-bit limit on 64-bit hosts.
12667 (exec_byte_code): Use tighter memory-full test, one that checks
12668 for alloca overflow. Don't compute the address of the object just
12669 before an array, as that's not portable. Use EMACS_INT, not
12670 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12671 * callint.c (Fcall_interactively):
12672 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12673 * callproc.c (call_process_kill, Fcall_process):

12684 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12685 (casify_object): Avoid integer overflow when overallocating buffer.
12686 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12687 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12688 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12689 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12690 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

12693 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12694 For CCL_MapSingle, check that content and value are in int range.
12695 (ccl_driver, Fregister_code_conversion_map):
12696 Check that Vcode_version_map_vector is a vector.
12697 (resolve_symbol_ccl_program): Check that vector header is in range.
12698 Always copy the vector, so that we can check its contents reliably
12699 now rather than having to recheck each instruction as it's being
12700 executed. Check that vector words fit in 'int'.
12701 (ccl_get_compiled_code, Fregister_ccl_program)
12702 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12703 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

12705 contents are in range.
12706 (Fccl_execute_on_string): Check that status is in range.
12707 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12708 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12709 Accept and return EMACS_INT, not int, because callers can pass values

12716 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12717 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12718 avoid mishandling large integers.

12728 (Fdefine_charset_internal): Check ranges here, more carefully.
12729 Don't rely on undefined behavior with signed left shift overflow.
12730 Don't assume unsigned int fits into fixnum, or that fixnum fits
12731 into unsigned int. Don't require max_code to be a valid fixnum;
12732 that's not true for gb10830 4-byte on a 32-bit host. Allow
12733 invalid_code to be a cons, for the same reason. Require code_offset
12734 to be a character. Avoid int overflow if max_char is close
12736 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12737 this is intended anyway and avoids some undefined behavior.
12738 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12739 INDEX_TO_CODE_POINT, as that's what it expects.
12740 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12741 * charset.h (DECODE_CHAR): Return int, not unsigned;
12742 this is what was intended anyway, and it avoids undefined behavior.
12743 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12744 integer-overflow issues.
12745 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12746 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12747 where the argument is EMACS_INT, and this behavior is not intended.
12748 * chartab.c (Fmake_char_table, Fset_char_table_range)
12749 (uniprop_get_decoder, uniprop_get_encoder):
12750 Don't assume fixnum fits in int.
12751 * cmds.c (move_point): New function, that does the gist of
12752 Fforward_char and Fbackward_char, but does so while checking
12753 for integer overflow more accurately.
12754 (Fforward_char, Fbackward_char): Use it.
12755 (Fforward_line, Fend_of_line, internal_self_insert)
12756 (internal_self_insert):
12757 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13526 (Fword_search_forward, Fword_search_backward_lax)
13527 (Fword_search_forward_lax): Move functions to isearch.el

13530 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13532 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13534 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13536 * lread.c (init_obarray): Declare Qt and Qnil as special.
13538 2012-05-14 Glenn Morris <rgm@gnu.org>
13540 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13541 Put "libexec" before "bin", for the sake of init_callproc_1.
13543 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13545 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

13548 (report_error, report_error_1, make_hdr, copy_sym)
13549 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13550 Make arguments const char *, not char *, to avoid violations of C
13551 standard and to fix some AIX warnings reported by Gilles Pion.
13553 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13555 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13556 already have overlays loaded.
13557 (handle_single_display_spec): Before returning without displaying
13558 fringe bitmap, synchronize the bidi iterator with the main display
13559 iterator, by calling iterate_out_of_display_property.
13560 (iterate_out_of_display_property): Detect buffer iteration by
13561 testing that it->string is a Lisp string.
13562 (get_next_display_element): When the current object is exhausted,
13563 and there's something on it->stack, call set_iterator_to_next to
13564 proceed with what's on the stack, instead of returning zero.
13565 (set_iterator_to_next): If called at the end of a Lisp string,
13566 proceed to consider_string_end without incrementing string
13567 position. Don't increment display vector index past the end of
13568 the display vector. (Bug#11417)
13569 (pos_visible_p): Don't report a position visible when move_it_to
13570 stopped at the last line of window, which happens to be scanned
13571 backwards by the bidi iteration. (Bug#11464)
13573 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13575 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13576 and right-margin display specs even if the spec is invalid or we
13577 are on a TTY, and thus unable to display on the fringes.
13578 That's because the text with the property will not be displayed anyway,
13579 so we need to signal to the caller that this is a "replacing"
13580 display spec. This fixes display when the spec is invalid or we
13583 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13585 * unexaix.c (make_hdr): Fix typo in prototype.
13586 This bug broke the build on AIX. Problem reported by Gilles Pion.
13588 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13590 * keyboard.c (kbd_buffer_get_event): Read special events also in
13591 batch mode. (Bug#11415)
13593 2012-05-12 Glenn Morris <rgm@gnu.org>
13595 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13597 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13599 * lisp.mk (lisp): Add newcomment.elc.
13601 2012-05-12 Glenn Morris <rgm@gnu.org>
13603 * Makefile.in (MKDIR_P): New, set by configure.
13604 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13606 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13608 Remove unused function hourglass_started.
13609 * dispextern.h (hourglass_started):
13610 * w32fns.c (hourglass_started):
13611 * xdisp.c (hourglass_started): Remove.
13613 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13615 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13616 Update dependencies.
13618 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13620 * xgselect.c (xg_select): Put maxfds+1 into a var.
13621 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13623 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13625 2012-05-10 Dave Abrahams <dave@boostpro.com>
13627 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13628 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13630 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13632 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13633 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13634 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13635 Initialize xd_registered_buses.
13637 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13639 Untag more efficiently if USE_LSB_TAG.
13640 This is based on a proposal by YAMAMOTO Mitsuharu in
13641 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13642 For an admittedly artificial (nth 8000 longlist) benchmark on
13643 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13644 Emacs's overall text size by 1%.
13645 * lisp.h (XUNTAG): New macro.
13646 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13647 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13648 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13649 * eval.c (Fautoload):
13650 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13651 * frame.h (XFRAME): Use XUNTAG.
13653 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13654 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13655 Remove unportable assumptions about print widths of types like
13657 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13658 intptr_t when converting between pointer and integer, to avoid GCC
13659 warnings about wrong width.
13661 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13663 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13664 stack for each reader_thread, instead of defaulting to 8MB
13665 determined by the linker. This avoids failures in creating
13666 subprocesses on Windows 7, see the discussion in this thread:
13667 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13669 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13671 Fix up display of the *Minibuf-0* buffer in the mini window.
13672 * keyboard.c (read_char): Don't clear the echo area if there's no
13674 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13675 contents of *Minibuf-0*) if there's no message displayed in its stead.
13677 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13679 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13682 2012-05-06 Chong Yidong <cyd@gnu.org>
13684 * lisp.mk (lisp): Update.
13686 2012-05-05 Jim Meyering <meyering@redhat.com>
13688 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13690 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13692 * data.c (PUT_ERROR): New macro.
13693 (syms_of_data): Use it. Add new error type `user-error'.
13694 * undo.c (user_error): New function.
13695 (Fprimitive_undo): Use it.
13696 * print.c (print_error_message): Adjust print style for `user-error'.
13697 * keyboard.c (user_error): New function.
13698 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13700 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13702 Do not limit current-time-string to years 1000..9999.
13703 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13704 (Fcurrent_time_string): Support any year that is supported by the
13705 underlying localtime representation. Don't use asctime, as it
13706 has undefined behavior for years outside the range -999..9999.
13708 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13710 Fix race conditions involving setenv, gmtime, localtime, asctime.
13711 Without this fix, interrupts could mess up code that uses these
13712 nonreentrant functions, since setting TZ invalidates existing
13713 tm_zone or tzname values, and since most of these functions return
13714 pointers to static storage.
13715 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13716 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13717 Grow the critical sections to include not just invoking
13718 localtime/gmtime, but also accessing these functions' results
13719 including their tm_zone values if any, and any related TZ setting.
13720 (format_time_string): Last arg is now struct tm *, not struct tm **,
13721 so that the struct tm is saved in the critical section.
13722 All callers changed. Simplify allocation of initial buffer, partly
13723 motivated by the fact that memory allocation needs to be outside
13724 the critical section.
13726 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13728 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13729 with RESET_INTERVAL.
13731 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13732 Remove duplicated buffer name initialization.
13734 2012-05-02 Jim Meyering <jim@meyering.net>
13736 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13738 * xfns.c (x_window): Use xstrdup (Bug#11375).
13740 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13742 * xdisp.c (pos_visible_p): If already at a newline from the
13743 display string before the 'while' loop, don't walk back the glyphs
13744 from it3.glyph_row. Solves assertion violation when the display
13745 string begins with a newline (egg.el). (Bug#11367)
13747 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13749 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13752 2012-05-01 Glenn Morris <rgm@gnu.org>
13754 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13755 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13756 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13757 All were removed before 23.1.
13759 * dispnew.c: Remove HAVE_LIBNCURSES test;
13760 it is always true on relevant platforms.
13762 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13763 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13765 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13767 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13769 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13770 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13773 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13775 Do not avoid creating empty evaporating overlays (Bug#9642).
13776 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13777 That is, do not delete an evaporating overlay if it becomes
13778 empty after its bounds are adjusted to fit within its buffer.
13779 This fix caused other problems, and I'm reverting it until we get
13780 to the bottom of them.
13782 2012-04-27 Chong Yidong <cyd@gnu.org>
13784 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13786 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13788 * xdisp.c (pos_visible_p): If the window start position is beyond
13789 ZV, start the display from buffer beginning. Prevents assertion
13790 violation in init_iterator when the minibuffer window is scrolled
13791 via the scroll bar.
13793 * window.c (window_scroll_pixel_based): Likewise.
13795 2012-04-27 Chong Yidong <cyd@gnu.org>
13797 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13799 2012-04-27 Glenn Morris <rgm@gnu.org>
13801 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13802 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13804 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13806 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13807 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13809 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13811 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13812 display element, check also the underlying string or buffer
13813 character. (Bug#11341)
13815 * w32menu.c: Include w32heap.h.
13816 (add_menu_item): If the call to AppendMenuW (via
13817 unicode_append_menu) fails, disable Unicode menus only if we are
13818 running on Windows 9X/Me.
13820 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13822 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13823 (xgetint): Add missing shift for LSB tags.
13825 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13827 * keyboard.c (read_char): Don't wipe echo area for select window
13828 events: These might get delayed via `mouse-autoselect-window'
13831 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13833 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13834 manipulation of :loaded-from data.
13836 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13838 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13839 now a cons (bug#11311).
13841 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13843 Do not create empty overlays with the evaporate property (Bug#9642).
13844 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13845 if it becomes empty after its bounds are adjusted to fit within
13846 its buffer. Without this fix, in a nonempty buffer (let ((o
13847 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13848 yields an empty overlay that has the evaporate property, which is
13849 not supposed to happen.
13851 Fix minor GTK3 problems found by static checking.
13852 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

13871 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13872 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13873 (__malloc_size_t, __malloc_ptrdiff_t):
13874 Remove. All uses removed, replaced by the definiens if needed,
13875 since we can assume C89 or better now.
13876 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

13883 (special_realloc, _realloc_internal_nolock, _realloc_internal)
13884 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13885 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13886 Define using prototypes, not old style.
13887 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):

13951 * alloc.c: Handle unusual debugging option combinations.
13952 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13953 since the two debugging options are incompatible.
13954 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

14008 row, return zero immediately.
14009 (try_cursor_movement): If inside continuation line, don't back up
14010 farther than the first row after the header line, if any.

14050 New extern decls, to avoid calling undeclared functions.
14051 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
14052 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined

14060 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
14061 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
14062 (r_alloc_sbrk): Now static.
14064 Improve ralloc.c interface checking.
14065 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
14066 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

14093 * s/netbsd.h, s/sol2-6.h:
14094 Remove definition of GC_MARK_STACK, since the default now works.
14095 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
14096 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
14097 no longer the default.
14098 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
14100 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

14112 * nsterm.m (constrainFrameRect): Always constrain when there is only
14113 one screen (Bug#10962).
14115 2012-04-13 Ken Brown <kbrown@cornell.edu>
14117 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
14119 2012-04-13 Reuben Thomas <rrt@sc3d.org>
14121 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
14123 2012-04-11 Daniel Colascione <dancol@dancol.org>
14125 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
14126 against is gone. It's better to use vfork now so that when Cygwin
14127 gains a new, working vfork, we use it automatically (bug#10398).
14129 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
14131 * window.c (save_window_save): Obey window-point-insertion-type.

14144 (force_quit_count): New var.
14145 (handle_interrupt): Use it.
14147 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
14149 * w32.c (w32_delayed_load): Record the full path of the library
14150 being loaded (bug#10424).
14152 2012-04-09 Glenn Morris <rgm@gnu.org>
14154 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
14155 not just in the obarray, before snarfing them. (Bug#11036)
14157 * Makefile.in ($(leimdir)/leim-list.el):
14158 Pass EMACS rather than BUILT_EMACS.
14160 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
14162 * process.c (make_process):
14163 * process.h: Add integer `gnutls_handshakes_tried' member to
14166 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
14167 Add convenience `GNUTLS_LOG2i' macro.
14169 * gnutls.c (gnutls_log_function2i): Convenience log function.
14170 (emacs_gnutls_read): Use new log functions,
14171 `gnutls_handshakes_tried' process member, and
14172 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
14173 attempts per process (connection).
14175 2012-04-09 Chong Yidong <cyd@gnu.org>
14177 * eval.c (Fuser_variable_p, user_variable_p_eh)
14178 (lisp_indirect_variable): Functions deleted.
14179 (Fdefvar): Caller changed.
14181 * callint.c (Finteractive, Fcall_interactively):
14182 * minibuf.c (Fread_variable): Callers changed.
14184 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14186 * xdisp.c (set_cursor_from_row): If the display string appears in
14187 the buffer at position that is closer to point than the position
14188 after the display string, display the cursor on the first glyph of
14189 the display string. Fixes cursor display when a 'display' text
14190 property immediately follows invisible text. (Bug#11094)
14192 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14194 composite.c: use 'double' consistently
14195 * composite.c (get_composition_id): Use 'double' consistently
14196 instead of converting 'float' to 'double' and vice versa; this is
14197 easier to understand and avoids a GCC warning.
14199 2012-04-09 Glenn Morris <rgm@gnu.org>
14201 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14202 preparation for dumping it with emacs. (Bug#4789)
14203 (leimdir): New variable.
14204 ($(leimdir)/leim-list.el): New rule.
14205 (emacs$(EXEEXT)): Depend on leim-list.el.
14207 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
14208 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
14209 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
14211 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>

14218 * xml.c (init_libxml2_functions) [WINDOWSNT]:
14219 Remove unused local variable.
14221 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
14223 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14224 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14225 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14226 objects, as mark_maybe_pointer will catch them otherwise.
14227 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
14228 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
14230 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
14232 Fix typo that broke non-Windows builds.
14233 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
14235 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14237 Support building on MS-Windows with libxml2.
14239 * makefile.w32-in (OBJ2): Add xml.$(O).
14240 (GLOBAL_SOURCES): Add xml.c.
14241 ($(BLD)/xml.$(O)): New dependency list.
14243 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
14244 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
14245 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
14246 [!WINDOWSNT]: New macros.
14247 (init_libxml2_functions, libxml2_loaded_p): New functions.
14248 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14249 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14250 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14251 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14253 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14254 Call init_libxml2_functions before calling libxml2 functions.
14255 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14257 * emacs.c: Don't include libxml/parser.h.
14258 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14259 xmlCleanupParser directly.
14261 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14263 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14265 * indent.c (Fvertical_motion): If there is a display string at
14266 point, use it.vpos to compute how many lines to backtrack after
14267 move_it_to point. (Bug#11133)
14269 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14271 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14272 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14273 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14274 macros related to unification of CJK characters. For the details,
14275 see the discussion following the message here:
14276 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14278 2012-04-04 Chong Yidong <cyd@gnu.org>
14280 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14282 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14284 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
14285 instead of alloca. (Bug#11138)
14287 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
14289 * w32menu.c (is_simple_dialog): Properly check lisp types.
14292 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14294 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14295 position we get to after a call to move_it_to fails the
14296 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14297 only if we wind up in a string from display property. (Bug#11063)
14299 * window.c (Fdelete_other_windows_internal): Invalidate the row
14300 and column information about mouse highlight, so that redisplay
14301 restores it after reallocating the glyph matrices. (Bug#7464)
14303 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14304 string comes from a `display' text property, use the buffer
14305 position of that property as if we actually saw that position in
14307 (move_it_by_lines): Remove the assertion that
14308 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14309 violated when there's a before-string at the beginning of a line.
14312 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14314 * xdisp.c (append_space_for_newline): If the default face was
14315 remapped, use the remapped face for the appended newline.
14316 (extend_face_to_end_of_line): Use the remapped default face for
14317 extending the face to the end of the line.
14318 (display_line): Call extend_face_to_end_of_line when the default
14319 face was remapped. (Bug#11068)
14321 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14323 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14325 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14327 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
14329 2012-03-27 Glenn Morris <rgm@gnu.org>
14331 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
14334 2012-03-26 Kenichi Handa <handa@m17n.org>
14336 * dispextern.h (struct glyph): Fix previous change. Change the
14337 bit length of glyphless.ch to 25 (Bug#11082).
14339 2012-03-26 Chong Yidong <cyd@gnu.org>
14341 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14342 (command_loop_1): Use it; inhibit selection update for
14343 handle-select-window too (Bug#8996).
14345 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
14347 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14349 2012-03-25 Kenichi Handa <handa@m17n.org>
14351 * dispextern.h (struct glyph): Change the bit length of
14352 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14354 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14356 * s/ms-w32.h (tzname): Include time.h before redirecting to
14357 _tzname. Fixes the MSVC build. (Bug#9960)
14359 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
14361 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14364 * xterm.c (XTread_socket): Only modify handling_signal if
14365 !SYNC_INPUT. (Bug#11080)
14367 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14369 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14370 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14371 when fetching a multibyte character consumes more bytes than
14372 CHAR_BYTES returns, due to unification of CJK characters in
14373 string_char. (Bug#11073)
14375 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14377 * process.c (wait_reading_process_output): Handle pty disconnect
14378 by refraining from sending oneself a SIGCHLD (bug#10933).
14380 2012-03-22 Chong Yidong <cyd@gnu.org>
14382 * dispextern.h (struct it): New member string_from_prefix_prop_p.
14384 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
14385 Mark string as coming from a prefix property.
14386 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14387 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14389 2012-03-21 Chong Yidong <cyd@gnu.org>
14391 * xfaces.c (Vface_remapping_alist): Doc fix.
14393 2012-03-20 Eli Zaretskii <eliz@gnu.org>
14395 * w32proc.c (Fw32_set_console_codepage)
14396 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
14399 2012-03-20 Chong Yidong <cyd@gnu.org>
14401 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
14402 to reflect default non-nil value of redisplay-dont-pause.
14404 2012-03-19 Kenichi Handa <handa@m17n.org>
14406 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
14407 it fit in a valid range (Bug#11003).
14409 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14411 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14412 that is not from display property, accept the row as a "cursor
14413 row" if one of the string's character has a non-nil `cursor'
14414 property. Fixes cursor positioning when there are newlines in
14415 overlay strings, e.g. in icomplete.el. (Bug#11035)
14417 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14419 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14421 2012-03-12 Chong Yidong <cyd@gnu.org>
14423 * eval.c (inhibit_lisp_code): Rename from
14424 inhibit_window_configuration_change_hook; move from window.c.
14426 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14427 * window.c (run_window_configuration_change_hook)
14428 (syms_of_window): Callers changed.
14430 2012-03-11 Chong Yidong <cyd@gnu.org>
14432 * keymap.c (Fkey_description): Doc fix (Bug#9700).
14434 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
14436 2012-03-10 Chong Yidong <cyd@gnu.org>
14438 * frame.c (other_visible_frames): Don't assume the selected frame
14439 is visible (Bug#10955).
14441 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
14443 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14445 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14447 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14448 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14451 2012-03-03 Glenn Morris <rgm@gnu.org>
14453 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14455 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14457 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14458 position past the first glyph_row that ends at ZV. (Bug#10902)
14459 (redisplay_window, next_element_from_string): Fix typos in
14461 (redisplay_window): Pass to move_it_vertically the margin in
14462 pixels, not in screen lines.
14464 2012-03-02 Glenn Morris <rgm@gnu.org>
14466 * buffer.c (buffer-list-update-hook): Doc fix.
14468 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14470 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14471 push_it before setting up the iterator for the first overlay
14472 string, even if we have an empty string loaded.
14473 (next_overlay_string): If there's an empty string on the iterator
14474 stack, pop the stack. (Bug#10903)
14476 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14478 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14479 Suggested by Stefan Monnier in
14480 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14481 * alloc.c (widen_to_Lisp_Object): New static function.
14482 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14483 and widening them to Lisp_Objects. This would work even if
14484 USE_LSB_TAG is defined and wide integers are used, which might
14485 happen in a future version of Emacs.
14487 2012-02-25 Chong Yidong <cyd@gnu.org>
14489 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14492 * xselect.c (Fx_selection_exists_p): Doc fix.
14493 (x_clipboard_manager_save_all): Print an informative message
14494 before saving to clipboard manager.
14496 2012-02-24 Chong Yidong <cyd@gnu.org>
14498 * keyboard.c (process_special_events): Handle all X selection
14499 requests in kbd_buffer, not just the next one (Bug#8869).
14501 2012-02-23 Chong Yidong <cyd@gnu.org>
14503 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14504 call when setting menu-bar-lines and tool-bar-lines parameters.
14505 (unwind_create_frame_1): New helper function.
14507 * window.c (inhibit_window_configuration_change_hook): New var.
14508 (run_window_configuration_change_hook): Obey it.
14509 (syms_of_window): Initialize it.
14511 2012-02-22 Chong Yidong <cyd@gnu.org>
14513 * xterm.c (x_draw_image_relief): Add missing type check for
14514 Vtool_bar_button_margin (Bug#10743).
14516 2012-02-21 Chong Yidong <cyd@gnu.org>
14518 * fileio.c (Vfile_name_handler_alist): Doc fix.
14520 * buffer.c (Fget_file_buffer): Protect against invalid file
14521 handler return value.
14523 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
14525 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
14526 when computing $valmask.
14528 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14529 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14530 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14531 It's useless in that case, and it can cause problems on hosts
14532 that allocate halves of EMACS_INT values separately.
14533 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14534 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14535 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14536 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14537 it avoids undefined behavior on hosts where shifting right by more
14538 than the word width has undefined behavior.
14540 2012-02-19 Chong Yidong <cyd@gnu.org>
14542 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14543 (Funhandled_file_name_directory, Ffile_name_as_directory)
14544 (Fdirectory_file_name, Fexpand_file_name)
14545 (Fsubstitute_in_file_name): Protect against invalid file handler
14546 return values (Bug#10845).
14548 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14550 * .gdbinit (pitx): Fix incorrect references to fields of the
14553 2012-02-17 Chong Yidong <cyd@gnu.org>
14555 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
14557 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
14559 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
14560 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14562 2012-02-15 Chong Yidong <cyd@gnu.org>
14564 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14565 marked as special. Also, starting docstrings with * is obsolete.
14567 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
14569 * gnutls.c (emacs_gnutls_write): Fix last change.
14571 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
14573 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
14576 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
14578 * keymap.c (Fsingle_key_description): Handle char ranges.
14580 2012-02-12 Chong Yidong <cyd@gnu.org>
14582 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14583 as that creates a dangerous corner case.
14585 * window.c (Fdelete_window_internal): Invalidate the mouse
14586 highlight (Bug#9904).

15148 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
15150 * keyboard.c (interrupt_signal): Don't call kill-emacs when

15153 2011-11-30 Eli Zaretskii <eliz@gnu.org>
15155 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
15156 verifies glyph row's hash code--we have just reallocated the
15157 glyphs, so their contents can be complete garbage. (Bug#10164)

15317 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
15318 Otherwise, valgrind does not work on some platforms.

15321 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15322 is set, removing the need for VIRT_ADDRESS_VARIES.
15323 (PURE_P): Use a more-efficient implementation that needs just one
15324 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the

15330 consistency with the new puresize.h.
15331 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
15332 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

15338 (erase_phys_cursor, update_window_cursor, show_mouse_face)
15339 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
15340 behave as if the cursor position were at the window margin.
15342 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15343 and the cursor position is out of bounds, behave as if the cursor
15344 position were at the window margin. (Bug#10075)
15346 2011-11-18 Chong Yidong <cyd@gnu.org>
15348 * window.c (Fwindow_combination_limit): Make first argument

15367 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
15369 * xdisp.c (row_hash): New function, body extracted from
15370 compute_line_metrics.
15371 (compute_line_metrics): Call row_hash, instead of computing the
15374 * dispnew.c (verify_row_hash): Call row_hash for computing the
15375 hash code of a row, instead of duplicating code from xdisp.c.
15377 * dispextern.h (row_hash): Add prototype.
15379 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
15381 * frame.c (delete_frame): Don't delete the terminal when the last

15417 * xdisp.c (display_line): Move the call to
15418 highlight_trailing_whitespace before the call to
15419 compute_line_metrics, since the latter needs to see the final

15430 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
15431 with user-defined heap size. Bump the default size of the temacs

15435 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15436 current_matrix and desired_matrix. (Bug#9990)
15437 (verify_row_hash) [XASSERTS]: New function.
15438 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify

15482 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
15484 Avoid some portability problems by eschewing 'extern inline' functions.
15485 The trivial performance wins aren't worth the portability hassles; see
15486 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15488 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

15537 This is also needed for porting to any host where GC_MARK_STACK is
15538 not GC_MAKE_GCPROS_NOOPS.
15539 (which_symbols): Use it.
15541 2011-11-07 Kenichi Handa <handa@m17n.org>

15554 * xmenu.c (cleanup_widget_value_tree): New function.
15555 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15556 calling free_menubar_widget_value_tree directly (Bug#9830).
15558 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
15560 Fix some portability problems with 'inline'.
15561 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
15562 (window_box_width, window_box_left, window_box_left_offset)
15563 (window_box_right, window_box_right_offset): Declare extern.
15564 Otherwise, these inline functions do not conform to C99 and
15565 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15566 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15567 * intervals.c (adjust_intervals_for_insertion)
15568 (adjust_intervals_for_deletion): Now extern, because otherwise the
15569 extern inline functions 'offset_intervals' couldn't refer to it.
15570 (static_offset_intervals): Remove.
15571 (offset_intervals): Rewrite using the old contents of
15572 static_offset_intervals. The old version didn't conform to C99
15573 because an extern inline function contained a reference to an
15574 identifier with static linkage.
15576 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
15578 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

15596 (Fwindow_vscroll): Doc fix.
15597 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
15598 argument, since it makes no sense to pass a live window and for
15599 consistency with window-child.

15640 official. Move initialization of image_cache_refcount and
15641 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15681 previous/next-single-property-change returns nil, treat that as
15682 the beginning or the end of the buffer. (Bug#9955)
15684 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
15686 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

15718 2011-10-30 Eli Zaretskii <eliz@gnu.org>
15720 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
15721 past the beginning of the current glyph matrix.
15723 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
15725 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.

15809 (w32font_open_internal, compute_metrics):
15810 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15811 instead of calling the "wide" APIs directly.
15813 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15815 * w32.h (syms_of_w32font): Add prototype.
15817 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

15824 2011-10-27 Chong Yidong <cyd@gnu.org>
15826 * process.c (make_process): Set gnutls_state to NULL.
15828 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15829 non-NULL, regardless of GNUTLS_INITSTAGE.
15830 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

15878 (bidi_resolve_weak): Don't enter the expensive loop if the current
15879 position is before next_en_pos. Record the bidi type of the first
15880 non-ET, non-BN character we find, in addition to its position.
15881 (bidi_level_of_next_char): Invalidate next_en_type when
15882 next_en_pos is over-stepped.
15884 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15886 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15887 * editfns.c: Rewrite current-time-zone so that it invokes
15888 the equivalent of (format-time-string "%Z") to get the time zone name.
15889 This fixes a bug when the time zone name contains characters that
15890 need converting from the system time locale to Emacs internal format.
15891 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15892 that patch fixed format-time-string to do the conversion, but
15893 I forgot to fix current-time-zone.
15894 (format_time_string): New function, containing most of
15895 what Fformat_time_string used to contain.
15896 (Fformat_time_string): Rewrite in terms of format_time_string.
15897 This doesn't change this function's behavior.
15898 (current-time-zone): Rewrite to use format_time_string.
15899 This fixes the bug reported by Michael Schierl in
15900 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15901 Jason Rumney's 2007-06-07 change worked around this bug, but
15903 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15905 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15907 * xdisp.c (start_display): If the character at POS is displayed
15908 via a display vector, reset IT->current.dpvec_index to zero.
15909 (try_window_reusing_current_matrix): If a line ends in a display
15910 vector or the next line starts in a display vector, continue
15911 redrawing the window even though the character position of
15912 start_row was reached.
15915 2011-10-18 Chong Yidong <cyd@gnu.org>
15917 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15918 with nobreak-char-display too.
15920 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15922 Fix part 3 of bug#9771.
15923 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15924 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15925 non-neutral characters if the current character is a paragraph
15926 separator (a.k.a. Newline). This avoids running the same
15927 expensive loop twice, once when we consume the preceding newline
15928 and the other time when the line actually needs to be displayed.
15929 Avoid the loop when we see neutrals on the base embedding level
15930 following a character whose directionality is the same as the
15931 paragraph's. This avoids running the expensive loop when a line
15932 ends in a long sequence of neutrals, like control characters.
15933 Add assertion against STRONG_AL type. Slightly rearrange code
15934 that determines the type of a neutral given the first non-neutral
15936 (bidi_level_of_next_char): Set next_en_pos to zero when
15937 invalidating its info.
15939 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15941 * xdisp.c (push_display_prop): Determine whether to record string
15942 or buffer position by IT->string, not by IT->method. Allow
15943 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15944 (move_it_vertically_backward): Don't look for character position
15945 immediately after the newline when in a continuation line.
15948 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15950 * window.c (coordinates_in_window): Rewrite and delabelize
15951 vertical border check. (Bug#5357) (Bug#9618)

15955 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15956 errors in XSetWindowBorder (bug#9310).
15958 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15960 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15961 avoid crash when xmalloc overrun checking is enabled.
15963 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15965 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15966 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15967 cursor motion with <left> and <right> arrow keys.
15969 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15970 some callers set that themselves.
15972 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15974 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15975 display string and the previous row comes from the same string and
15976 is empty. (Bug#9739) (Bug#9738)
15978 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>

15984 * bidi.c (bidi_level_of_next_char):
15985 * xdisp.c (get_visually_first_element): Remove old incorrect
15986 comments regarding the Unicode Line Separator character.
15988 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15990 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15992 * alloc.c (Fgc_status): Do not access beyond zombies array
15993 boundary if nzombies > MAX_ZOMBIES.
15994 * alloc.c (dump_zombies): Add missing format specifier.
15996 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15998 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15999 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
16001 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
16002 Some packages use them to denote characters with modifiers.
16004 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
16006 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
16007 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
16008 matching a pp-number. Rename parameter var to var1.
16010 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
16012 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
16014 2011-10-08 Glenn Morris <rgm@gnu.org>
16016 * callint.c (Fcall_interactively): Give a more explicit error for the
16017 'c' case with a non-character input. (Bug#8479)
16019 2011-10-08 Eli Zaretskii <eliz@gnu.org>
16021 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
16023 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
16024 lines that are hscrolled on the left.
16026 * dispnew.c (buffer_posn_from_coords): Account for a possible
16027 presence of header-line. (Bug#4426)
16029 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
16031 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
16032 Don't advertise functionality which we discourage or doesn't work.
16034 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
16036 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
16037 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
16038 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
16039 this makes Emacs dump core during garbage collection on rare
16040 occasions. sizeof is obviously inferior to offsetof here, so
16041 stick with offsetof.
16042 (GC_POINTER_ALIGNMENT): New macro.
16043 (mark_memory): Omit 3rd (offset) arg; caller changed.
16044 Don't assume EMACS_INT alignment is the same as pointer alignment.
16046 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16048 * keyboard.c (read_key_sequence_remapped): New var.
16049 (read_key_sequence): Compute remapping in the right buffer.
16050 (command_loop_1): Use read_key_sequence's remapping directly.
16052 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16054 * dired.c (file_name_completion): Don't expand file name.
16055 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16056 before checking file name handler.
16058 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16059 they've been requested explicitly (bug#9591).
16061 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16063 * keymap.c (Fsingle_key_description): Use make_specified_string
16064 instead of build_string to build string from push_key_description.
16067 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16069 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16070 This fixes a Y2038 bug on 64-bit hosts.
16071 * buffer.c (reset_buffer):
16072 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16073 (Fclear_buffer_auto_save_failure):
16074 Use 0, not -1, to represent an unset failure time, since time_t
16075 might not be signed.
16077 Remove dependency on glibc malloc internals.
16078 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16079 Move back here from lisp.h, but with their new implementations.
16080 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16081 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16082 * charset.c (charset_table_init): New static var.
16083 (syms_of_charset): Use it instead of xmalloc. This removes a
16084 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16085 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16086 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16087 Move back to alloc.c.
16088 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16089 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16091 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16093 * nsterm.m (windowDidResize): Call x_set_window_size only when
16094 ns_in_resize is true. Otherwise set pixelwidth/height and
16095 call change_frame_size (Bug#9628).
16097 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16099 Port --enable-checking=all to Fedora 14 x86-64.
16100 * charset.c (syms_of_charset): Also account for glibc malloc's
16101 internal overhead when calculating the initial malloc maximum.
16103 Port --enable-checking=all to Fedora 14 x86.
16104 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16106 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16107 (overrun_check_realloc, overrun_check_free):
16108 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16109 That way, xmalloc returns a properly-aligned pointer even if
16110 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16111 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16112 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16113 into account when calculating the initial malloc maximum.
16114 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16115 Move here from alloc.c, so that charset.c can use it too.
16116 Properly align; the old code wasn't right for common 32-bit hosts
16117 when configured with --enable-checking=all.
16118 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16119 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16121 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16123 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16126 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16128 * xdisp.c (compute_display_string_end): If there's no display
16129 string at CHARPOS, return -1.
16131 * bidi.c (bidi_fetch_char): When compute_display_string_end
16132 returns a negative value, treat the character as a normal
16133 character not covered by a display string. (Bug#9624)
16135 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16137 * lread.c (Fread_from_string): Fix typo in docstring.
16139 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16141 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16142 newline, reseat the iterator instead of bidi-iterating there one
16143 character at a time. (Bug#9610)
16144 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16145 TO_CHARPOS if the bidi iterator is at base embedding level.
16147 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16149 * lread.c (readevalloop): Use correct code for NBSP.
16150 (read1): Likewise. (Bug#9608)
16152 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16154 * dbusbind.c (Fdbus_register_signal): When service is not
16155 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16157 2011-09-25 Glenn Morris <rgm@gnu.org>
16159 * buffer.c (truncate-lines): Doc fix.
16161 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16163 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16164 (Fset_window_next_buffers): Doc fix.
16166 2011-09-24 Glenn Morris <rgm@gnu.org>
16168 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16170 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16172 Fix minor problems found by static checking.
16173 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16174 * indent.c (Fvertical_motion): Fix == vs = typo.
16176 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16178 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16179 Default value is now t. Doc fix.
16181 * indent.c (Fvertical_motion): Compute and apply the overshoot
16182 logic when moving up, not only when moving down. Fix the
16183 confusing name and values of the it_overshoot_expected variable;
16184 logic changes accordingly. (Bug#9254) (Bug#9549)
16186 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16187 CHARPOS is covered by a display string which includes newlines.
16188 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16189 is covered by a display string with embedded newlines.
16191 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16193 * dbusbind.c (Fdbus_register_signal): Add match rule to
16194 Vdbus_registered_objects_table. (Bug#9581)
16195 (Fdbus_register_method, Vdbus_registered_objects_table):
16198 2011-09-24 Jim Meyering <meyering@redhat.com>
16200 do not ignore write error for any output size
16201 The previous change was incomplete.
16202 While it makes emacs --batch detect the vast majority of stdout
16203 write failures, errors were still ignored whenever the output size is
16204 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16205 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16206 && echo FAIL: ignored write error
16207 FAIL: ignored write error
16208 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16209 && echo FAIL: ignored write error
16210 FAIL: ignored write error
16211 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16213 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16215 * emacs.c (Fkill_emacs): In noninteractive mode exit
16216 non-successfully if a write error occurred on stdout. (Bug#9574)
16218 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16220 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16223 * dispextern.h (struct it): Update the comment documenting what
16226 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16228 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16229 a display string, extend search for cursor position to end of row.
16230 (find_row_edges): If the row ends in a newline from a display
16231 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16232 Handle the case of a display string with multiple newlines.
16233 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16234 non-empty line. Fixes confusing cursor motion with arrow keys at
16235 the beginning of a line that starts with whitespace.
16237 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16239 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16242 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16244 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16245 boolean (Bug#9154).
16247 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16249 * xdisp.c (display_line): Record maximum and minimum buffer
16250 positions even if no glyphs were produced (e.g., by a zero-width
16251 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16252 buffer positions that will be removed from the glyph row because
16254 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16255 column is beyond frame width: don't subtract 1 "pixel" when
16256 computing width of the stretch.
16257 (reseat_at_next_visible_line_start): Undo the change made on
16258 2011-09-17 that saved paragraph information and restored it after
16259 the call to `reseat'. (Bug#9545)
16261 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16263 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16264 and turn window cursor on if cleared (Bug#9415).
16266 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16268 * search.c (boyer_moore): Take unibyte characters from pattern
16269 literally. (Bug#9458)
16271 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16273 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16275 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16277 Fix minor problem found by static checking.
16278 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16279 initialized, to pacify gcc -Wuninitialized.
16281 * fileio.c: Report proper errno when syscall falls.
16282 (Finsert_file_contents): Save and restore errno,
16283 so that report_file_error outputs the correct diagnostic.
16284 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16286 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16288 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16290 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16292 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16293 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16295 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16297 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16298 about the current paragraph and restore it after the call to reseat.
16300 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16301 (bidi_find_paragraph_start): Search back for paragraph beginning
16302 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16303 (bidi_move_to_visually_next): Only trigger paragraph-related
16304 computations when the last character is a newline or at EOB, not
16305 just any NEUTRAL_B. (Bug#9470)
16307 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16308 truncated lines if point is covered by a display string. (Bug#9524)
16310 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16312 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16313 (cons_to_x_long): New function.
16314 (lisp_data_to_selection_data): Use it. Correct the test for
16315 short-versus-long data; it was negated. Break out of vector
16316 loop, for efficiency, when a long datum is discovered.
16318 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16320 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16322 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16324 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16325 GCC PR/17406) by declaring this function with external scope.
16327 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16329 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16330 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16332 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16334 * editfns.c (Fformat): Correctly handle text properties on "%%".
16336 2011-09-15 Eli Zaretskii <eliz@gnu.org>
16338 * xterm.c (x_draw_composite_glyph_string_foreground):
16339 * w32term.c (x_draw_composite_glyph_string_foreground):
16340 * term.c (encode_terminal_code):
16341 * composite.c (composition_update_it, get_composition_id):
16342 * xdisp.c (get_next_display_element)
16343 (fill_composite_glyph_string): Add comments about special meaning
16344 of TAB characters in a composition.
16346 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16348 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16349 This occurs when processing a multibyte format.
16350 Problem reported by Wolfgang Jenker.
16352 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16354 * xdisp.c (try_cursor_movement): Only check for exact match if
16355 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16357 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16359 Remove unused external symbols.
16360 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16361 * xdisp.c (calc_pixel_width_or_height): Now static.
16362 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16363 * indent.c (check_display_width):
16364 * w32term.c: Fix comment to match code.
16365 * xterm.c, xterm.h (x_catching_errors): Remove.
16367 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16369 * xselect.c: Use signed conversions more consistently (Bug#9498).
16370 (selection_data_to_lisp_data): Assume incoming selection data are
16371 signed integers, not unsigned. This is to be consistent with
16372 outgoing selection data, which was modified to use signed integers
16373 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16374 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16375 expects long, not unsigned long.
16377 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16379 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16380 computation of loop end. Reported by Johan Bockgård
16383 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16385 * frame.c (Fother_visible_frames_p): Function deleted.
16387 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16389 * indent.c (compute_motion): Process display vector front to back
16390 rather than the other way around. (Bug#2496)
16392 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16394 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16396 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16398 * minibuf.c (Fread_from_minibuffer): Doc fix.
16400 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16402 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16403 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16405 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16407 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16408 value for non-existent files.
16410 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16412 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16413 set its "size" to -1. This will set the modtime_size field of
16414 the corresponding buffer to -1, which is what
16415 verify-visited-file-modtime expects for files that do not exist.
16418 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16420 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16422 * lisp.h: ... from here. push_key_description is no longer
16423 defined in keyboard.c, so its declaration should not be in
16424 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16425 logically belongs with push_key_description.
16427 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16429 * buffer.h: Include <sys/types.h> instead of <time.h>.
16430 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16431 Problem reported by Herbert J. Skuhra.
16433 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16435 * xml.c (parse_region): Make the parsing work for
16436 non-comment-starting XML files again (bug#9144).
16438 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16440 * image.c (gif_load): Fix calculation of bottom and right corner.
16443 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16445 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16446 redisplay in small windows.
16448 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16450 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16452 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16454 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16455 Operate on live windows only.
16457 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16459 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16461 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16463 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16464 only under bidi iteration.
16466 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16468 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16470 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16472 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16473 Without this fix, the command to link temacs failed due to an
16474 undefined symbol __builtin_isnan. This is because
16475 /usr/include/iso/math_c99.h #defines isnan(x) to
16476 __builtin_isnan(x), but the bundled gcc, which identifies itself
16477 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16479 * floatfns.c (isnan): #undef, and then #define to a clone of
16481 (Fisnan): Always define, since it's always available now.
16482 (syms_of_floatfns): Always define isnan at the Lisp level.
16484 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16486 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16488 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16490 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16491 The previous code assumed that file offsets (off_t values) fit in
16492 EMACS_INT variables, which is not true on typical 32-bit hosts.
16493 The code messed up by falsely reporting buffer overflow in cases
16494 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16495 when "big" contains more than 2**29 bytes, even though this
16496 inserts just one byte and does not overflow the buffer.
16497 (Finsert_file_contents): Store file offsets as off_t
16498 values, not as EMACS_INT values. Check for overflow when
16499 converting between EMACS_INT and off_t. When checking for
16500 buffer overflow or for overlap, take the offsets into account.
16501 Don't use EMACS_INT for small values where int suffices.
16502 When checking for overlap, fix a typo: ZV was used where
16503 ZV_BYTE was intended.
16504 (Fwrite_region): Don't assume off_t fits into 'long'.
16505 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16507 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16509 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16511 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16513 sprintf-related integer and memory overflow issues (Bug#9412).
16515 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16516 (esprintf, exprintf, evxprintf): New functions.
16517 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16518 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16519 (modify_event_symbol): Do not assume that the length of
16520 name_alist_or_stem is safe to alloca and fits in int.
16521 (Fexecute_extended_command): Likewise for function name and binding.
16522 (Frecursion_depth): Wrap around reliably on integer overflow.
16523 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16524 since some callers pass EMACS_INT values.
16525 (Fsingle_key_description): Don't crash if symbol name contains more
16526 than MAX_ALLOCA bytes.
16527 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16528 (get_minibuffer): Arg is now EMACS_INT, not int.
16529 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16530 (esprintf, exprintf, evxprintf): New decls.
16531 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16533 * dbusbind.c (signature_cat): New function.
16534 (xd_signature, Fdbus_register_signal):
16535 Do not overrun buffer; instead, report string overflow.
16537 * dispnew.c (add_window_display_history): Don't overrun buffer.
16538 Truncate instead; this is OK since it's just a log.
16540 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16541 even if the time zone offset is outlandishly large.
16542 Don't mishandle offset == INT_MIN.
16544 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16545 when creating daemon; the previous buffer-overflow check was incorrect.
16547 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16548 which has the guts of the old verror function.
16550 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16551 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16553 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16554 (font_unparse_xlfd): Don't blindly alloca long strings.
16555 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16556 fits in int, when using sprintf. Use single snprintf to count
16557 length of string rather than counting it via multiple sprintfs;
16558 that's simpler and more reliable.
16559 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16560 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16561 sprintf, in case result does not fit in int.
16563 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16564 (fontset_from_font): Print it.
16566 * frame.c (tty_frame_count): Now printmax_t, not int.
16567 (make_terminal_frame, set_term_frame_name): Print it.
16568 (x_report_frame_params): In X, window IDs are unsigned long,
16569 not signed long, so print them as unsigned.
16570 (validate_x_resource_name): Check for implausibly long names,
16571 and don't assume name length fits in 'int'.
16572 (x_get_resource_string): Don't blindly alloca invocation name;
16573 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16576 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16577 (xg_check_special_colors, xg_set_geometry):
16578 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16580 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16581 Use esprintf, not sprintf, in case result does not fit in int.
16583 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16584 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16585 it as a large positive number.
16586 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16587 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16589 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16590 in case result does not fit in int.
16592 * print.c (float_to_string): Detect width overflow more reliably.
16593 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16594 buffer overrun. Don't assume list length fits in 'int'. Treat
16595 print length of 0 as 0, not as infinity; to be consistent with other
16596 uses of print length in this function. Don't overflow print length
16597 index. Don't assume hash table size fits in 'long', or that
16598 vectorlike size fits in 'unsigned long'.
16600 * process.c (make_process): Use printmax_t, not int, to format
16601 process-name gensyms.
16603 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16605 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16606 to avoid potential buffer overrun.
16608 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16609 if X resource line is longer than 512 bytes.
16611 * xfns.c (x_window): Make sprintf buffer a bit bigger
16612 to avoid potential buffer overrun.
16614 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16616 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16618 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16620 Integer overflow fixes for scrolling, etc.
16621 Without these, Emacs silently mishandles large integers sometimes.
16622 For example, "C-u 4294967297 M-x recenter" was treated as if
16623 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16625 * xdisp.c (try_window_id): Check Emacs fixnum range before
16626 converting to 'int'.
16628 * window.c (window_scroll_line_based, Frecenter):
16629 Check that an Emacs fixnum is in range before assigning it to 'int'.
16630 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16631 values converted from Emacs fixnums.
16632 (Frecenter): Don't wrap around a line count if it is out of 'int'
16633 range; instead, treat it as an extreme value.
16634 (Fset_window_configuration, compare_window_configurations):
16635 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16637 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16638 that can exceed INT_MAX. Check that EMACS_INT value is in range
16639 before assigning it to the (possibly-narrower) index.
16640 (match_limit): Don't assume that a fixnum can fit in 'int'.
16642 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16645 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16646 (Fvertical_motion): Don't wrap around LINES values that don't fit
16647 in 'int'. Instead, treat them as extreme values. This is good
16648 enough for windows, which can't have more than INT_MAX lines anyway.
16650 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16652 * Require libxml/parser.h to avoid compilation warning.
16654 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16656 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16657 since this reportedly can destroy thread storage.
16659 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16661 * syntax.c (find_defun_start): Update all cache variables if
16662 exiting early (Bug#9401).
16664 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16666 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16668 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16669 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16670 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16672 * term.c (tty_append_glyph): New function.
16673 (produce_stretch_glyph): Static function and its prototype deleted.
16675 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16678 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16680 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16681 when checking :margin (Bug#9390).
16682 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16683 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16684 so that the name doesn't mislead. All uses changed.
16686 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16688 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16691 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16693 * xdisp.c (move_it_to): Don't bail out early when reaching
16694 position beyond to_charpos, if we are scanning backwards.
16695 (move_it_vertically_backward): When DY == 0, make sure we get to
16696 the first character in the line after the newline.
16698 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16700 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16701 (ccl_driver): Do not generate an out-of-range pointer.
16702 (Fccl_execute_on_string): Remove unnecessary check for
16703 integer overflow, noted by Stefan Monnier in
16704 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16705 Remove a FIXME that didn't need fixing.
16706 Simplify the newly-introduced buffer reallocation code.
16708 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16710 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16712 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16714 Integer and memory overflow issues (Bug#9196).
16716 * doc.c (get_doc_string): Rework so that
16717 get_doc_string_buffer_size is the actual buffer size, rather than
16718 being 1 less than the actual buffer size; this makes xpalloc more
16721 * image.c (x_allocate_bitmap_record, cache_image):
16722 * xselect.c (Fx_register_dnd_atom):
16723 Simplify previous changes by using xpalloc.
16725 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16726 since either will do and ptrdiff_t is convenient with xpalloc.
16728 * charset.c (charset_table_size)
16729 (struct charset_sort_data.priority): Now ptrdiff_t.
16730 (charset_compare): Don't overflow if priorities differ greatly.
16731 (Fsort_charsets): Don't assume list length fits in int.
16732 Check for size-calculation overflow when allocating sort data.
16733 (syms_of_charset): Allocate an initial charset table that is
16734 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16736 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16738 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16739 The actual value is always <= INT_MAX, and leaving it unsigned made
16740 overflow checking harder.
16742 * dispextern.h (struct glyph_matrix.rows_allocated)
16743 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16744 with xpalloc. The values are still always <= INT_MAX.
16746 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16748 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16749 (SAFE_NALLOCA): New macro.
16751 * region-cache.c (struct boundary.pos, find_cache_boundary)
16752 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16753 (set_cache_region, invalidate_region_cache)
16754 (revalidate_region_cache, know_region_cache, region_cache_forward)
16755 (region_cache_backward, pp_cache):
16756 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16757 so that ptrdiff_t * can be passed to xpalloc.
16758 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16759 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16760 (pp_cache): Don't assume cache_len fits in int.
16761 * region-cache.h: Adjust extern decls to match.
16763 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16764 EMACS_INT, since either will do, for xpalloc.
16766 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16767 (xnmalloc, xnrealloc, xpalloc): New functions.
16769 * bidi.c (bidi_shelve_header_size): New constant.
16770 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16771 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16773 * bidi.c (bidi_cache_shrink):
16774 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16776 Don't update size of array until after memory allocation succeeds,
16777 because xmalloc/xrealloc may not return.
16778 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16779 now that we have proper integer overflow checking.
16780 (record_overlay_string, overlay_strings): Catch overflows when
16781 calculating size of overlay_str_buf.
16783 * callproc.c (Fcall_process): Check for size overflow when
16784 calculating size of args2.
16785 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16786 Normally we prefer signed values, but sticking with ptrdiff_t would
16787 require adding more-complicated checks.
16789 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16790 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16791 Redo buffer-overflow calculations to avoid integer overflow.
16792 Add a FIXME comment where memory seems to be over-allocated.
16794 * character.c (Fstring): Check for size-calculation overflow.
16796 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16797 unnecessary integer overflow. Check for size overflow.
16798 (encode_coding_object): Don't update size until xmalloc succeeds.
16800 * composite.c (get_composition_id): Check for overflow in glyph
16801 length calculations.
16803 Integer and memory overflow fixes for display code.
16804 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16805 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16806 (scrolling_window): Check for overflow in size calculations.
16807 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16808 Don't assume glyph table len fits in int.
16809 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
16810 (row_table_size): Now ptrdiff_t, not int.
16811 (scrolling_window): Avoid overflow in size calculations.
16812 Don't update size until allocation succeeds.
16813 * fns.c (concat): Check for overflow in size calculations.
16814 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16815 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16816 (NEXT_ALMOST_PRIME_LIMIT): New constant.
16818 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16819 (get_doc_string): Check for size calculation overflow.
16820 Don't update size until allocation succeeds.
16821 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16822 EMACS_INT, where ptrdiff_t will do.
16823 (Fsubstitute_command_keys): Check for string overflow.
16825 * editfns.c (set_time_zone_rule): Don't assume environment length
16827 (message_length): Now ptrdiff_t, not int.
16828 (Fmessage_box): Don't update size until allocation succeeds.
16829 Don't assume message length fits in int.
16830 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16832 * emacs.c (main): Do not reallocate argv, since there is a null at
16833 the end that can be overwritten, and this way there's no need to
16834 worry about size-calculation overflow.
16835 (sort_args): Check for size-calculation overflow.
16837 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16839 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16841 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16842 (x_set_scroll_bar_width, x_figure_window_size):
16843 Check for integer overflow.
16844 (x_set_alpha): Do not assume XINT fits in int.
16846 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16847 This is for the members text_lines, text_cols, total_lines, total_cols,
16848 where the system imposes an 'int' limit.
16850 * fringe.c (Fdefine_fringe_bitmap):
16851 Don't update size until alloc works.
16853 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16854 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16856 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16857 Check for size-calculation overflow.
16858 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16859 do, as we prefer signed integers.
16860 (id_to_widget.max_size, id_to_widget.used)
16861 (xg_store_widget_in_map, xg_remove_widget_from_map)
16862 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16863 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16864 Use and return ptrdiff_t, not int.
16865 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16866 * gtkutil.h: Change prototypes to match the above.
16868 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16869 are duplicate now that they've been promoted to lisp.h.
16870 (x_allocate_bitmap_record, x_alloc_image_color)
16871 (make_image_cache, cache_image, xpm_load):
16872 Don't update size until alloc is done.
16873 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
16875 Check for size calculation overflow.
16876 (ct_colors_allocated_max): New constant.
16877 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
16880 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
16881 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
16882 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16883 Use ptrdiff_t, not int, to count maps.

16913 (Fset_match_data): Don't assume list lengths fit in 'int'.
16915 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16916 for command line length. Do not attempt to address one before the
16917 beginning of an array, as that's not portable.

16949 memory exhaustion (the usual treatment), rather than aborting.
16951 * xfns.c (x_encode_text, x_set_name_internal)
16952 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16953 sizes, since they can exceed INT_MAX in size. Check for size
16954 calculation overflow.
16956 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16957 (xg_select): Check for size calculation overflow.
16958 Don't update size until alloc done.
16960 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16961 as sprintf is limited to int lengths.
16963 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16964 (X_LONG_MIN): New macros.
16965 Use them to make the following changes clearer.
16966 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16967 This change doesn't affect the value now, but it may help remind
16968 future maintainers not to raise the value too much later.
16969 (SELECTION_QUANTUM): Remove, replacing with ...
16970 (selection_quantum): ... new function, which avoids overflow.
16972 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16973 assumption that selection length fits in 'int'.
16974 (x_reply_selection_request, x_handle_selection_request)
16975 (x_get_window_property, receive_incremental_selection)

16990 Don't store size until memory allocation succeeds.
16991 (x_get_window_property): Plug memory leak on memory exhaustion.
16992 Don't double-block input; malloc is safe here. Don't assume 2**34
16993 - 4 fits in unsigned long. Add an xassert to check
16994 XGetWindowProperty overflow. Be more careful about overflow
16995 calculations, and distinguish size from memory overflow better.
16996 (receive_incremental_selection): When tracing, don't assume
16997 unsigned int is less than INT_MAX.
16998 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

17001 in the range -65535 through -1 fit in an X unsigned short.
17002 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
17003 result parameters unless successful. Rely on cons_to_unsigned
17004 to report problems with elements; the old code wasn't right anyway.
17005 (x_check_property_data): Check for int overflow; we cannot use
17006 a wider type due to X limits.
17007 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

17039 * lisp.h (hash_lookup, hash_put):
17040 * minibuf.c (Ftest_completion):
17041 Use ptrdiff_t for hash table indexes, not int (which is too
17042 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
17043 32-bit --with-wide-int hosts).
17045 * charset.c (Fdefine_charset_internal): Check for integer overflow.
17046 Add a FIXME comment about memory leaks.

17054 with outlandish widths.
17055 * character.h (sanitize_tab_width): Rename from sanitize_width,
17056 now that we have two such functions. All uses changed.

17074 * xterm.c: Don't go over XClientMessageEvent limit.
17075 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17076 (x_send_scroll_bar_event): Likewise. Check that the size does not
17077 exceed limits imposed by XClientMessageEvent, as well as the usual
17078 ptrdiff_t and size_t limits.
17080 * keyboard.c: Overflow, signedness and related fixes.
17081 (make_lispy_movement): Use same integer type in forward decl
17082 that is used in the definition.
17083 (read_key_sequence, keyremap_step):
17084 Change bufsize argument back to int, undoing my 2011-03-30 change.
17085 We prefer signed types, and int is wide enough here.
17086 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17087 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17088 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17089 length, not size_t. Use ptrdiff_t for index, not int.
17090 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17091 possibility of integer overflow.
17093 Overflow, signedness and related fixes for images.

17117 since parse_image_check makes sure they fit into int.
17118 (png_load, gif_load, svg_load_image):
17119 Prefer int to unsigned where either will do.
17120 (tiff_handler): New function, combining the cores of the
17121 old tiff_error_handler and tiff_warning_handler.
17122 This function is rewritten to use vsnprintf and thereby avoid
17123 stack buffer overflows. It uses only the features of vsnprintf
17124 that are common to both POSIX and native Microsoft.
17125 (tiff_error_handler, tiff_warning_handler): Use it.
17126 (tiff_load, gif_load, imagemagick_load_image):
17127 Don't assume :index value fits in 'int'.
17128 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17129 (imagemagick_load_image): Check that crop parameters fit into
17130 the integer types that MagickCropImage accepts. Don't assume
17131 Vimagemagick_render_type has a nonnegative value. Don't assume
17132 size_t fits in 'long'.
17133 (gs_load): Use printmax_t to print the widest integers possible.

17146 handle_single_display_spec, not just 1 or zero.
17147 (handle_single_display_spec): If the display spec is of the form
17148 `(space ...)', and specifies display in the text area, return 2
17150 (try_cursor_movement): Check for the need to scroll more
17151 accurately, and prefer exact match for point under bidi.
17152 Don't advance `row' beyond the last row of the window.

17170 buffers, return left-to-right.
17171 (set_cursor_from_row): Consider candidate row a win if its glyph
17172 represents a newline and point is on that newline. Fixes cursor
17173 positioning on the newline at EOL of R2L text within L2R
17174 paragraph, and vice versa.
17175 (try_cursor_movement): Check continued rows, in addition to
17176 continuation rows. Fixes unwarranted scroll when point enters a
17177 continued line of R2L text within an L2R paragraph, or vice versa.
17178 (cursor_row_p): Consider the case of point being equal to
17179 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

17209 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17210 candidate is selected by the mouse, and that candidate has a
17211 composed character under the mouse.
17213 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17214 coordinates reported by pos-visible-in-window-p for a composed
17215 character in column zero.

17223 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17224 consider it a hit if to_charpos is anywhere in the range of the
17225 composed buffer positions.
17227 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17229 * image.c (gif_load): Don't assume that each subimage has the same
17230 dimensions as the base image. Handle disposal method that is
17231 "undefined" by the gif spec (Bug#9335).
17233 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17235 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17245 a composition, take its buffer position from IT->cmp_it.charpos.
17246 Fixes cursor positioning at the beginning of a line that begins
17247 with a composed character.
17249 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17251 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17252 character bidirectional type, use STRONG_L instead. Fixes crashes
17253 in a buffer produced by `describe-categories'.
17255 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17256 members before the level stack, so they would be saved and
17257 restored when copying iterator state. Fixes incorrect reordering
17258 around TABs covered by display properties.

17332 * xdisp.c (move_it_in_display_line_to): Don't invoke
17333 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17334 ppos_it. Fixes vertical cursor motion when line beginning is
17335 covered by an image. (Bug#9296)
17337 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17339 * nsterm.h (ns_run_ascript): Declare.
17340 (NSAPP_DATA2_RUNASSCRIPT): Define.
17342 * nsfns.m (as_script, as_result, as_status): New static variables.
17343 (ns_run_ascript): New function.
17344 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17345 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17346 the event loop. Get status from as_status (Bug#7276).
17348 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17349 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17350 the event loop (Bug#7276).
17352 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17354 * gnutls.c (QCgnutls_bootprop_priority)
17355 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
17356 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
17357 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
17358 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
17359 (QCgnutls_bootprop_verify_hostname_error)
17360 (QCgnutls_bootprop_callbacks_verify): Rename from
17361 Qgnutls_bootprop_..., all uses changed.
17363 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
17366 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
17368 * xfaces.c (Qframe_set_background_mode): Now static.
17369 * dispextern.h (Qframe_set_background_mode): Remove decl.
17371 * process.c (Fnetwork_interface_info): Declare local only if needed.
17373 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
17375 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
17376 (Fnetwork_interface_list): Allocate in increments of bytes instead
17377 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17378 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17380 (struct ifflag_def): notrailers is smart on OSX.
17381 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17382 Get hardware address with getifaddrs if available.
17384 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17386 * xdisp.c (iterate_out_of_display_property): xassert that
17387 IT->position is set to within IT->object's boundaries. Break from
17388 the loop as soon as EOB is reached; avoids infloops in redisplay
17389 when IT->position is set up wrongly due to some bug.
17390 Set IT->current to match the bidi iterator unconditionally.
17391 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17392 entry. Force push_it to save on the stack the current
17393 buffer/string position, to be restored by pop_it. Fix flags in
17394 the iterator structure wrt the object coming from a display
17395 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17396 properties. (Bug#9284)
17398 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17400 * fontset.c (fontset_get_font_group): Add proper type checks.
17403 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17405 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
17406 and LC_VERSION_MIN_MACOSX.
17407 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
17408 (dump_it) [LC_FUNCTION_STARTS]: Use it.
17410 2011-08-08 Eli Zaretskii <eliz@gnu.org>
17412 * xdisp.c (forward_to_next_line_start): Allow to use the
17413 no-display-properties-and-no-overlays under bidi display.
17414 Set disp_pos in the bidi iterator to avoid searches for display
17415 properties and overlays.
17417 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17419 * editfns.c (Fset_time_zone_rule): Document relationship with the
17422 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
17423 the font entity extracted from the cache (Bug#8109).
17425 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17427 * composite.c (autocmp_chars): Don't reset point. That is done by
17428 restore_point_unwind (Bug#5984).
17430 2011-08-07 Juri Linkov <juri@jurta.org>
17432 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17433 to show the arg `TIME' instead of `TIMEVAL'.
17435 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17437 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17438 display property strides EOL and includes a newline, as in
17439 longlines-mode. (Bug#9254)
17440 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17441 word-wrap under bidirectional display. (Bug#9224)
17443 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17444 is non-zero, even if the data buffer is NULL. Fixes a crash in
17445 vertical-motion with longlines-mode. (Bug#9254)
17447 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17449 * bidi.c <bidi_cache_total_alloc>: Now static.
17450 (bidi_initialize): Initialize bidi_cache_total_alloc.
17452 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17455 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17456 amount allocated this far in `bidi_cache_total_alloc'.
17457 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17458 non-zero, only free the data buffer without restoring the cache
17459 contents. All callers changed.
17461 * dispextern.h (bidi_unshelve_cache): Update prototype.
17463 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17464 (move_it_in_display_line, move_it_to)
17465 (move_it_vertically_backward, move_it_by_lines): Replace the call
17466 to xfree to an equivalent call to bidi_unshelve_cache.
17467 (move_it_in_display_line_to): Fix logic of returning
17468 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17470 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17472 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17473 came from a string character with a `cursor' property. (Bug#9229)
17475 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17477 * Makefile.in (LIB_PTHREAD): New variable.
17478 (LIBES): Add LIB_PTHREAD (Bug#9216).
17480 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17481 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17483 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17485 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17487 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17489 * xterm.c (x_find_topmost_parent): New function.
17490 (x_set_frame_alpha): Find topmost parent window with
17491 x_find_topmost_parent and set the property there also (bug#9181).
17492 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17494 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17496 * callproc.c (Fcall_process): Avoid vfork clobbering
17497 the local vars buffer, coding_systems, current_dir.
17499 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17501 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17503 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17505 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17506 so that it is not optimized away.
17508 * xdisp.c (compute_display_string_pos): Remove unused local.
17510 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17512 Fix slow cursor motion and scrolling in large buffers with
17513 selective display, like Org Mode buffers. (Bug#9218)
17515 * dispextern.h (struct bidi_it): New member disp_prop_p.
17517 * xdisp.c: Remove one-slot cache of display string positions.
17518 (compute_display_string_pos): Accept an additional argument
17519 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17520 for a display string or property. If found, set DISP_PROP_P
17523 * bidi.c (bidi_fetch_char): Accept an additional argument
17524 DISP_PROP_P, and pass it to compute_display_string_pos.
17525 Only handle text covered by a display string if DISP_PROP_P is returned
17526 non-zero. All callers of bidi_fetch_char changed.
17528 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17530 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17532 2010-12-03 Don March <don@ohspite.net>
17534 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17535 last character M-[char] is translated to ESC [char] (bug#7541).
17537 2011-08-02 Kenichi Handa <handa@m17n.org>
17539 * lisp.h (uniprop_table): Extern it.
17541 * chartab.c (uniprop_table): Make it non-static.
17543 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17545 * xdisp.c (forward_to_next_line_start): Accept additional argument
17546 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17548 (reseat_at_next_visible_line_start): Use the bidi iterator state
17549 returned by forward_to_next_line_start to restore the state of
17550 it->bidi_it after backing up to previous newline. (Bug#9212)
17552 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17554 * regex.c (re_comp): Protoize.
17555 (re_exec): Fix return type.
17556 (regexec): Fix type of `ret'. (Bug#9203)
17558 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17560 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17561 This is needed if max-image-size is a floating-point number.
17563 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17565 * print.c (print_object): Print empty symbol as ##.
17567 * lread.c (read1): Read ## as empty symbol.
17569 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17571 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17572 setting frame foreground color (Bug#9175).
17573 (x_set_background_color): Likewise.
17575 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17576 contents (Bug#9176).
17577 (EmacsTooltip -init): Remove bezels and add shadows to
17580 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17581 or scroll bar (Bug#8470).
17583 * nsfont.m (nsfont_open): Remove assignment to voffset and
17584 unnecessary vars hshink, expand, hd, full_height, min_height.
17585 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17587 * nsterm.h (nsfont_info): Remove voffset field.
17589 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17591 Implement strike-through and overline on NextStep (Bug#8863).
17593 * nsfont.m (nsfont_open): Use underline position provided by font,
17594 instead of hard-coded value of 2.
17595 (nsfont_draw): Call ns_draw_text_decoration instead.
17597 * nsterm.h: Add declaration for ns_draw_text_decoration.
17599 * nsterm.m (ns_draw_text_decoration): New function for drawing
17600 underline, overline, and strike-through.
17601 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17602 ns_draw_text_decoration. Change treatment of cursor drawing to
17603 accommodate underlining, etc.
17605 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17607 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17610 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17612 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17613 Without this fix, if a signal arrives just after memory fills up,
17614 'malloc' might be invoked reentrantly.
17616 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17617 In other words, assume that every image size is allowed, on non-X
17618 hosts. This assumption is probably wrong, but it lets Emacs compile.
17620 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17622 * regex.c (re_iswctype): Convert return values to boolean.
17624 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17626 * xdisp.c (compute_display_string_pos): Don't use cached display
17627 string position if the buffer had its restriction changed.
17630 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17632 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17634 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17636 Integer signedness and overflow and related fixes. (Bug#9079)
17638 * bidi.c: Integer size and overflow fixes.
17639 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17640 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17641 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17642 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17643 (bidi_find_other_level_edge):
17644 Use ptrdiff_t instead of EMACS_INT where either will do.
17645 This works better on 32-bit hosts configured --with-wide-int.
17646 (bidi_cache_ensure_space): Check for size-calculation overflow.
17647 Use % rather than repeated addition, for better worst-case speed.
17648 Don't set bidi_cache_size until after xrealloc returns, because it
17650 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17651 (bidi_cache_ensure_space): Also check that the bidi cache size
17652 does not exceed that of the largest Lisp string or buffer. See Eli
17653 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17655 * alloc.c (__malloc_size_t): Remove.
17656 All uses replaced by size_t. See Andreas Schwab's note
17657 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17659 * image.c: Improve checking for integer overflow.
17660 (check_image_size): Assume that f is nonnull, since
17661 it is always nonnull in practice. This is one less thing to
17662 worry about when checking for integer overflow later.
17663 (x_check_image_size): New function, which checks for integer
17664 overflow issues inside X.
17665 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17666 This removes the need for a memory_full check.
17667 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17668 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17669 (xbm_read_bitmap_data): Change locals back to 'int', since
17670 their values must fit in 'int'.
17671 (xpm_load_image, png_load, tiff_load):
17672 Invoke x_create_x_image_and_pixmap earlier,
17673 to avoid much needless work if the image is too large.
17674 (tiff_load): Treat overly large images as if
17675 x_create_x_image_and_pixmap failed, not as malloc failures.
17676 (gs_load): Use x_check_image_size.
17678 * gtkutil.c: Omit integer casts.
17679 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17680 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17682 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17684 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17685 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17686 would wrongly return t on a 64-bit host.
17688 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17689 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17690 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17691 and therefore cause GCC to emit a bogus diagnostic in some cases.
17693 * image.c: Integer signedness and overflow and related fixes.
17694 This is not an exhaustive set of fixes, but it's time to
17695 record what I've got.
17696 (lookup_pixel_color, check_image_size): Remove redundant decls.
17697 (check_image_size): Don't assume that arbitrary EMACS_INT values
17698 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17699 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17700 (tiff_load, imagemagick_load_image):
17701 Check for overflow in size calculations.
17702 (x_create_x_image_and_pixmap): Remove unnecessary test for
17703 xmalloc returning NULL; that can't happen.
17704 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17705 (xpm_color_bucket): Use better integer hashing function.
17706 (xpm_cache_color): Don't possibly over-allocate memory.
17707 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17708 (gif_memory_source):
17709 Use ptrdiff_t, not int or size_t, to record sizes.
17710 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17711 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17712 either works, as we prefer signed integers.
17713 (tiff_read_from_memory, tiff_write_from_memory):
17714 Return tsize_t, not size_t, since that's what the TIFF API wants.
17715 (tiff_read_from_memory): Don't fail simply because the read would
17716 go past EOF; instead, return a short read.
17717 (tiff_load): Omit no-longer-needed casts.
17718 (Fimagemagick_types): Don't assume size fits into 'int'.
17720 Improve hashing quality when configured --with-wide-int.
17721 * fns.c (hash_string): New function, taken from sxhash_string.
17722 Do not discard information about ASCII character case; this
17723 discarding is no longer needed.
17724 (sxhash-string): Use it. Change sig to match it. Caller changed.
17725 * lisp.h: Declare it.
17726 * lread.c (hash_string): Remove, since we now use fns.c's version.
17727 The fns.c version returns a wider integer if --with-wide-int is
17728 specified, so this should help the quality of the hashing a bit.
17730 * emacs.c: Integer overflow minor fix.
17731 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17732 Define only if GNU_LINUX.
17733 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17735 * dispnew.c: Integer signedness and overflow fixes.
17736 Remove unnecessary forward decls, that were a maintenance hassle.
17737 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17739 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17740 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17741 (prepare_desired_row, line_draw_cost):
17742 Use int, not unsigned, where either works.
17743 (save_current_matrix, restore_current_matrix):
17744 Use ptrdiff_t, not size_t, where either works.
17745 (init_display): Check for overflow more accurately, and without
17746 relying on undefined behavior.
17748 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17749 Remove, replacing with the new symbols in lisp.h. All uses changed.
17750 * fileio.c (make_temp_name):
17751 * filelock.c (lock_file_1, lock_file):
17752 * xdisp.c (message_dolog):
17753 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17754 Use pMd etc. instead.
17755 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17756 replacing the pWIDE etc. symbols removed from editfns.c.
17758 * keyboard.h (num_input_events): Now uintmax_t.
17759 This is (very slightly) less likely to mess up due to wraparound.
17762 * buffer.c: Integer signedness fixes.
17763 (alloc_buffer_text, enlarge_buffer_text):
17764 Use ptrdiff_t rather than size_t when either will do, as we prefer
17767 * alloc.c: Integer signedness and overflow fixes.
17768 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17769 (__malloc_size_t): Default to size_t, not to int.
17770 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17771 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17772 Prefer ptrdiff_t to size_t when either would do, as we prefer
17774 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17775 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17776 Now const. Initialize with values that are in range even if char
17778 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17779 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17780 These functions do the right thing with sizes > 2**32.
17781 (check_depth): Now ptrdiff_t, not int.
17782 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17783 Adjust to new way of storing sizes. Check for size overflow bugs
17785 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17786 slightly wrong anyway, as it missed one instance of
17787 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17788 (refill_memory_reserve): Omit needless cast to size_t.
17789 (mark_object_loop_halt): Mark as externally visible.
17791 * xselect.c: Integer signedness and overflow fixes.
17792 (Fx_register_dnd_atom, x_handle_dnd_message):
17793 Use ptrdiff_t, not size_t, since we prefer signed.
17794 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17795 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17796 x_dnd_atoms_size and x_dnd_atoms_length.
17798 * doprnt.c: Prefer signed to unsigned when either works.
17800 * doprnt.c (doprnt):
17802 * xdisp.c (vmessage):
17803 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17804 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17805 prefer signed arithmetic to avoid comparison confusion.
17806 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17807 but is a bit tricky.
17809 Assume freestanding C89 headers, string.h, stdlib.h.
17810 * data.c, doprnt.c, floatfns.c, print.c:
17811 Include float.h unconditionally.
17812 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17813 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17814 * regex.c: Likewise for stddef.h, string.h.
17815 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17816 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17817 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17818 (STDC_HEADERS): Remove obsolete defines.
17819 * sysdep.c: Include limits.h unconditionally.
17821 Assume support for memcmp, memcpy, memmove, memset.
17822 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17823 * regex.c (memcmp, memcpy):
17824 Remove; we assume C89 now.
17826 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17827 (__malloc_safe_bcopy): Remove; no longer needed.
17829 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17830 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17831 well either way, and we prefer signed to unsigned.
17833 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17835 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17836 closes the connection while we're reading (bug#9182).
17838 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17840 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17841 are specified (Bug#9168).
17843 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17845 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17846 Found by GCC static checking and --with-wide-int on a 32-bit host.
17848 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17850 * xdisp.c (compute_display_string_pos): Fix logic of caching
17851 previous display string position. Initialize cached_prev_pos to
17852 -1. Fixes slow-down at the beginning of a buffer.
17854 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17856 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17857 for attrs[LFACE_FONTSET_INDEX].
17859 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17861 * xml.c (parse_region): Remove unused local
17862 that was recently introduced.
17864 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17866 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17867 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17869 * xdisp.c (move_it_in_display_line_to): Record the best matching
17870 position for TO_CHARPOS while scanning the line, and restore it on
17871 exit if none of the characters scanned was an exact match.
17872 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17873 when exact match is impossible due to invisible text, and the
17874 lines are truncated.
17876 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17878 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17881 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17883 Fix a significant slow-down of cursor motion with C-n, C-p,
17884 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17885 auto-repeat under bidi redisplay in fontified buffers.
17886 * xdisp.c (compute_stop_pos_backwards): New function.
17887 (next_element_from_buffer): Call compute_stop_pos_backwards to
17888 find a suitable prev_stop when we find ourselves before
17890 (reseat): Don't look for prev_stop, as that could mean a very long
17892 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17893 <cached_disp_overlay_modiff>: Cache for last found display string
17895 (compute_display_string_pos): Return the cached position if asked
17896 about the same buffer in the same area of character positions, and
17897 the buffer wasn't changed since the time the display string
17898 position was cached.
17900 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17902 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17903 is an integer, which is important for empty lines. (Bug#9149)
17905 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17907 * frame.c (Fmodify_frame_parameters): In tty case, update the
17908 default face if necessary (Bug#4238).
17910 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17912 * editfns.c (Fstring_to_char): No need to explain what a character
17913 is in the docstring (Bug#6576).
17915 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17917 * xml.c (parse_region): Make sure we always return a tree.
17919 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17921 * xml.c (parse_region): If a document contains only comments,
17924 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17926 * xml.c (make_dom): Return comments, too.
17928 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17931 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17932 and the surrounding thread.
17933 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17934 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17935 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17937 * s/openbsd.h (BROKEN_SIGIO): Define.
17938 * unexelf.c (unexec) [__OpenBSD__]:
17939 Don't update the .mdebug section of the Alpha COFF symbol table.
17941 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17943 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17946 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17948 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17949 This fixes some race conditions on the permissions of any newly
17952 * alloc.c (valid_pointer_p): Use pipe, not open.
17953 This fixes some permissions issues when debugging.
17955 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17956 If fchown fails to set both uid and gid, try to set just gid,
17957 as that is sometimes allowed. Adjust the file's mode to eliminate
17958 setuid or setgid bits that are inappropriate if fchown fails.
17960 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17962 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17963 to compare Lisp_Objects.
17964 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17965 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17966 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17968 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17970 * lread.c (read_integer): Unread even EOF character.
17971 (read1): Likewise. Properly record start position of symbol.
17973 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17974 symbol character follows.
17976 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17978 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17979 This works around a problem with the previous change to Fcopy_file.
17980 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17981 and without this change, GCC might complain about discarding
17982 fchown's return value.
17984 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17986 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17988 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17990 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17992 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17994 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17995 it's used from the C level.
17997 * process.c: Use the same condition for POLL_FOR_INPUT in both
17998 keyboard.c and process.c (bug#1858).
18000 2011-07-09 Lawrence Mitchell <wence@gmx.li>
18002 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
18003 (Fgnutls_boot): Use it.
18005 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
18007 * doc.c (Fsubstitute_command_keys): Revert last change.
18009 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
18011 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
18012 quotes the next character, and doesn't affect other longer
18013 sequences (bug#8935).
18015 * lread.c (syms_of_lread): Clarify that is isn't only
18016 `eval-buffer' and `eval-defun' that's affected by
18017 `lexical-binding' (bug#8460).
18019 2011-07-15 Eli Zaretskii <eliz@gnu.org>
18021 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
18022 bidi redisplay when a line includes both an image and is truncated.
18024 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
18026 Fix minor problems found by static checking.
18027 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
18028 (elsz): Now a signed constant, not a size_t var. We prefer signed
18029 types to unsigned, to avoid integer comparison confusion. Without
18030 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
18031 "cannot optimize loop, the loop counter may overflow", a symptom
18033 * indent.c (Fvertical_motion): Mark locals as initialized.
18034 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
18036 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
18038 * search.c (Fre_search_backward): Mention `case-fold-search' in
18039 all the re_search_* functions (bug#8138).
18041 * keyboard.c (Fopen_dribble_file): Document when the file is

18052 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
18053 (reseat_to_string): Initialize bidi_it->string.s and
18054 bidi_it->string.schars.
18055 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
18056 NULL (avoids a crash in bidi_paragraph_init).
18057 Initialize itb.string.lstring.
18058 (init_iterator): Call bidi_init_it only of a valid
18059 buffer position was specified. Initialize paragraph_embedding to
18061 (reseat_to_string): Initialize the bidi iterator.
18062 (display_string): If we need to ignore text properties of
18063 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18064 original value of -1 will not work with bidi.)
18065 (compute_display_string_pos): First arg is now struct
18066 `text_pos *'; all callers changed. Support display properties on
18068 (compute_display_string_end): Support display properties on Lisp
18070 (init_iterator, reseat_1, reseat_to_string): Initialize the
18071 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18072 when iterating on a string not from display properties).
18073 (compute_display_string_pos, compute_display_string_end):
18074 Fix calculation of the object to scan. Fixes an error when using
18076 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18077 base_level_stop; instead, set base_level_stop to BEGV.
18078 Fixes crashes in vertical-motion.
18079 (next_element_from_buffer): Improve commentary for when
18080 the iterator is before prev_stop.
18081 (init_iterator): Initialize bidi_p from the default value of
18082 bidi-display-reordering, not from buffer-local value. Use the
18083 buffer-local value only if initializing for buffer iteration.
18084 (handle_invisible_prop): Support invisible properties on strings
18085 that are being bidi-reordered.
18086 (set_iterator_to_next): Support bidi reordering of C strings and
18088 (next_element_from_string): Support bidi reordering of Lisp
18090 (handle_stop_backwards): Support Lisp strings as well.
18091 (display_string): Support display of R2L glyph rows.
18092 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18093 (init_iterator): Don't initialize it->bidi_p for strings
18095 (reseat_to_string): Initialize it->bidi_p for strings here.
18096 (next_element_from_string, next_element_from_c_string)
18097 (next_element_from_buffer): Add xassert's for correspondence
18098 between IT's object being iterated and it->bidi_it.string
18100 (face_before_or_after_it_pos): Support bidi iteration.
18101 (next_element_from_c_string): Handle the case of the first string
18102 character that is not the first one in the visual order.
18103 (get_visually_first_element): New function, refactored from common
18104 parts of next_element_from_buffer, next_element_from_string, and
18105 next_element_from_c_string.
18106 (tool_bar_lines_needed, redisplay_tool_bar)
18107 (display_menu_bar): Force left-to-right direction. Add a FIXME
18108 comment for making that be controlled by a user option.
18109 (push_it, pop_it): Save and restore the state of the
18110 bidi iterator. Save and restore the bidi_p flag.
18111 (pop_it): Iterate out of display property for string iteration as
18113 (iterate_out_of_display_property): Support iteration over strings.
18114 (handle_single_display_spec): Set up it->bidi_it for iteration
18115 over a display string, and call bidi_init_it.
18116 (handle_single_display_spec, next_overlay_string)
18117 (get_overlay_strings_1, push_display_prop): Set up the bidi
18118 iterator for displaying display or overlay strings.
18119 (forward_to_next_line_start): Don't use the shortcut if
18121 (back_to_previous_visible_line_start): If handle_display_prop
18122 pushed the iterator stack, restore the internal state of the bidi
18123 iterator by calling bidi_pop_it same number of times.
18124 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18125 and we are bidi-iterating, don't decrement the iterator position;
18126 instead, set the first_elt flag in the bidi iterator, to produce
18128 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18129 (push_display_prop): xassert that we are iterating a buffer.
18130 (push_it, pop_it): Save and restore paragraph_embedding member.
18131 (handle_single_display_spec, next_overlay_string)
18132 (get_overlay_strings_1, reseat_1, reseat_to_string)
18133 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18134 correctly. Don't assume unibyte strings are not bidi-reordered.
18135 (compute_display_string_pos)
18136 (compute_display_string_end): Fix handling the case of C string.
18137 (push_it, pop_it): Save and restore from_disp_prop_p.

18142 popping after iteration over a string that came from a display
18143 property. Fix a typo in popping stretch info. Add an assertion
18144 for verifying that the iterator position is in sync with the bidi
18146 (handle_single_display_spec, get_overlay_strings_1)
18147 (push_display_prop): Fix initialization of paragraph direction for
18148 string when that of the parent object is not yet determined.
18149 (reseat_1): Call bidi_init_it to resync the bidi
18150 iterator with IT's position. (Bug#7616)
18151 (find_row_edges): If ROW->start.pos gives position
18152 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
18153 (handle_stop, back_to_previous_visible_line_start, reseat_1):
18154 Reset the from_disp_prop_p flag.
18155 (SAVE_IT, RESTORE_IT): New macros.
18156 (pos_visible_p, face_before_or_after_it_pos)
18157 (back_to_previous_visible_line_start)
18158 (move_it_in_display_line_to, move_it_in_display_line)
18159 (move_it_to, move_it_vertically_backward, move_it_by_lines)
18160 (try_scrolling, redisplay_window, display_line): Use them when
18161 saving a temporary copy of the iterator and restoring it back.
18162 (back_to_previous_visible_line_start, reseat_1)
18163 (init_iterator): Empty the bidi cache "stack".
18164 (move_it_in_display_line_to): If iterator ended up at
18165 EOL, but we never saw any buffer positions smaller than
18166 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
18167 motion in bidi-reordered lines.
18168 (move_it_in_display_line_to): Record prev_method and prev_pos
18169 immediately before the call to set_iterator_to_next. Fixes cursor
18170 motion in bidi-reordered lines with stretch glyphs and strings
18171 displayed in margins. (Bug#8133) (Bug#8867)
18172 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
18174 (pos_visible_p): Support positions in bidi-reordered lines.
18175 Save and restore bidi cache.
18177 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
18178 (bidi_paragraph_info): Delete unused struct.
18179 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
18180 (bidi_cache_start): New variable.
18181 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
18183 (bidi_cache_fetch_state, bidi_cache_search)
18184 (bidi_cache_find_level_change, bidi_cache_iterator_state)
18185 (bidi_cache_find, bidi_peek_at_next_level)

18189 (bidi_fetch_char): Accept new argument STRING; all callers
18190 changed. Support iteration over a string. Support strings with
18191 display properties. Support unibyte strings. Fix the type of
18192 `len' according to what STRING_CHAR_AND_LENGTH expects.
18193 (bidi_paragraph_init, bidi_resolve_explicit_1)
18194 (bidi_resolve_explicit, bidi_resolve_weak)
18195 (bidi_level_of_next_char, bidi_move_to_visually_next):
18196 Support iteration over a string.
18197 (bidi_set_sor_type, bidi_resolve_explicit_1)
18198 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
18199 can now be zero (for strings); special values 0 and -1 were
18200 changed to -1 and -2, respectively.
18201 (bidi_char_at_pos): New function.
18202 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
18203 Call it instead of FETCH_MULTIBYTE_CHAR.
18204 (bidi_move_to_visually_next): Abort if charpos or bytepos were not

18290 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
18291 The old code sometimes used this field without initializing it.
18293 * alloc.c (gc_sweep): Don't read past end of array.
18294 In theory, the old code could also have corrupted Emacs internals,
18295 though it'd be very unlikely.

18560 This isn't true in general, and it's particularly not true
18561 if Emacs is configured with --with-wide-int.
18562 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

18599 Random fixes. E.g., (random) never returned negative values.
18600 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18601 subseconds part to the entropy, as that's a bit more random.
18602 Prefer signed to unsigned, since the signedness doesn't matter and
18603 in general we prefer signed. When given a limit, use a
18604 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18605 latter isn't right if USE_2_TAGS_FOR_INTS.
18606 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18607 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18619 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18620 This is more efficient than Ffile_directory_p and avoids a minor race.
18622 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18624 * buffer.c (Foverlay_put): Say what the return value is
18627 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18628 is a directory before asking whether to use the file name
18630 (barf_or_query_if_file_exists): Make the "File is a directory"
18631 error be more correct.
18633 * fns.c (Frequire): Remove the mention of the .gz files, since
18634 that's installation-specific, but keep the mention of
18635 `get-load-suffixes'.

18639 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18647 Qgnutls_bootprop_verify_error (which is no longer used).

18752 * eval.c (struct backtrace): Simplify and port the data structure.
18753 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18754 signed bit field, as this assumption is not portable and it makes
18755 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18756 "char debug_on_exit : 1" as this is not portable either; instead,
18757 use the portable "unsigned int debug_on_exit : 1". Remove unused
18758 member evalargs. Remove obsolete comments about cc bombing out.
18760 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18948 (read1): Check for integer overflow in radices, and in
18949 read-circle numbers.
18950 (read_escape): Avoid int overflow.
18951 (Fload, openp, read_buffer_size, read1)

18994 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18995 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18996 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18997 since we're not interested in debugging glyphs with old libraries.
18998 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18999 GCC 4.6.0's static checking.

19089 Don't assume pid_t and time_t fit in unsigned long.
19090 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19091 (current_lock_owner): Prefer signed type for sizes.
19092 Use memcpy, not strncpy, where memcpy is what is really wanted.
19093 Don't assume (via atoi) that time_t and pid_t fit in int.
19094 Check for time_t and/or pid_t out of range, e.g., via a network share.
19095 Don't alloca where an auto var works fine.
19097 * fileio.c: Fix some integer overflow issues.
19098 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19099 Don't assume string length fits in int.
19100 (directory_file_name): Don't assume string length fits in long.
19101 (make_temp_name): Don't assume pid fits in int, or that its print
19102 length is less than 20.
19104 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19106 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19108 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19110 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19111 We prefer signed integers, even for size calculations.
19113 * emacs.c: Don't assume string length fits in 'int'.
19114 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19115 (main): Don't invoke strlen when not needed.
19117 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
19118 (XD_DEBUG_MESSAGE): Don't waste a byte.
19120 * callproc.c (getenv_internal_1, getenv_internal)
19121 (Fgetenv_internal):
19122 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19124 * lread.c (invalid_syntax): Omit length argument.
19125 All uses changed. This doesn't fix a bug, but it simplifies the
19126 code away from its former Hollerith-constant appearance, and it's
19127 one less 'int' to worry about when looking at integer-overflow issues.
19128 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19130 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19131 This didn't break anything, but it didn't help either.
19132 It's confusing to put a bogus integer in a place where the actual
19133 value does not matter.
19134 (LIST_END_P): Remove unused macro and its bogus comment.
19135 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19137 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19138 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19140 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19141 We prefer signed types, and the value cannot exceed the EMACS_INT
19142 range anyway (because otherwise the length would not be representable).
19143 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19144 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19145 This avoids a GCC warning when WIDE_EMACS_INT.
19147 * indent.c (sane_tab_width): New function.
19148 (current_column, scan_for_column, Findent_to, position_indentation)
19149 (compute_motion): Use it. This is just for clarity.
19150 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19152 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19154 * lisp.h (lint_assume): New macro.
19155 * composite.c (composition_gstring_put_cache):
19156 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19158 * editfns.c, insdel.c:
19159 Omit unnecessary forward decls, to simplify future changes.
19161 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19163 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19165 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19166 Use much-faster test for byte-length change.
19167 Don't assume string byte-length fits in 'int'.
19168 Check that character arg fits in 'int'.
19169 (mapcar1): Declare byte as byte, for clarity.
19171 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19173 * fns.c (concat): Catch string overflow earlier.
19174 Do not rely on integer wraparound.
19176 * dispextern.h (struct it.overlay_strings_charpos)
19177 (struct it.selective): Now EMACS_INT, not int.
19178 * xdisp.c (forward_to_next_line_start)
19179 (back_to_previous_visible_line_start)
19180 (reseat_at_next_visible_line_start, next_element_from_buffer):
19181 Don't arbitrarily truncate the value of 'selective' to int.
19183 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19185 * composite.c: Don't truncate sizes to 'int'.
19186 (composition_gstring_p, composition_reseat_it)
19187 (composition_adjust_point): Use EMACS_INT, not int.
19188 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19189 not EMACS_UINT, for indexes.
19191 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19193 * buffer.c: Include <verify.h>.
19194 (struct sortvec.priority, struct sortstr.priority):
19195 Now EMACS_INT, not int.
19196 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19197 (struct sortstr.size, record_overlay_string)
19198 (struct sortstrlist.size, struct sortlist.used):
19199 Don't truncate size to int.
19200 (record_overlay_string): Check for size-calculation overflow.
19201 (init_buffer_once): Check at compile-time, not run-time.
19203 2011-06-22 Jim Meyering <meyering@redhat.com>
19205 Don't leak an XBM-image-sized buffer
19206 * image.c (xbm_load): Free the image buffer after using it.
19208 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19211 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19212 that Sun C diagnosed.
19213 * fns.c (secure_hash): Fix pointer signedness issue.
19214 * intervals.c (static_offset_intervals): New function.
19215 (offset_intervals): Use it.
19217 2011-06-21 Leo Liu <sdl.web@gmail.com>
19220 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19223 * fns.c (secure_hash): Rename from crypto_hash_function and change
19224 the first arg to accept symbols.
19225 (Fsecure_hash): New primitive.
19226 (syms_of_fns): New symbols.
19228 2011-06-20 Deniz Dogan <deniz@dogan.se>
19230 * process.c (Fset_process_buffer): Clarify return value in
19233 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19235 * dispnew.c (add_window_display_history): Use BVAR.
19237 * xdisp.c (debug_method_add): Use BVAR.
19238 (check_window_end, dump_glyph_matrix, dump_glyph)
19239 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19241 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19244 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19245 check till after the cache is created in init_frame_faces.
19247 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19249 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19251 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19253 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19254 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19255 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19257 Improve buffer-overflow checking (Bug#8873).
19258 * fileio.c (Finsert_file_contents):
19259 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19260 Remove the old (too-loose) buffer overflow checks.
19261 They weren't needed, since make_gap checks for buffer overflow.
19262 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19263 The old code merely checked for Emacs fixnum overflow, and relied
19264 on undefined (wraparound) behavior. The new code avoids undefined
19265 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19267 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19268 Tune. Don't use wider integers than needed. Don't use alloca.
19269 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19271 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19273 * insdel.c, lisp.h (buffer_overflow): New function.
19274 (insert_from_buffer_1, replace_range, replace_range_2):
19275 * insdel.c (make_gap_larger):
19276 * editfns.c (Finsert_char):
19277 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19279 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19281 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19283 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19285 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19286 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19288 * fileio.c: Don't assume EMACS_INT fits in off_t.
19289 (emacs_lseek): New static function.
19290 (Finsert_file_contents, Fwrite_region): Use it.
19291 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19293 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19295 * fns.c: Don't overflow int when computing a list length.
19296 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19297 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19298 truncation on 64-bit hosts. Check for QUIT every
19299 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19300 faster and is responsive enough.
19301 (Flength): Report an error instead of overflowing an integer.
19302 (Fsafe_length): Return a float if the value is not representable
19303 as a fixnum. This shouldn't happen except in contrived situations.
19304 (Fnthcdr, Fsort): Don't assume list length fits in int.
19305 (Fcopy_sequence): Don't assume vector length fits in int.
19307 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19308 (header_size, word_size): New constants.
19309 (allocate_vectorlike): Don't check size overflow here.
19310 (allocate_vector): Check it here instead, since this is the only
19311 caller of allocate_vectorlike that could cause overflow.
19312 Check that the new vector's length is representable as a fixnum.
19314 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19315 The previous code was bogus. For example, next_almost_prime (32)
19316 returned 39, which is undesirable as it is a multiple of 3; and
19317 next_almost_prime (24) returned 25, which is a multiple of 5 so
19318 why was the code bothering to check for multiples of 7?
19320 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19322 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19324 Variadic C functions now count arguments with ptrdiff_t.
19325 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19326 Back then I didn't know that the Emacs coding style prefers signed int.
19327 Also, in the meantime I found a few more instances where arguments
19328 were being counted with int, which may truncate counts on 64-bit
19329 machines, or EMACS_INT, which may be unnecessarily wide.
19330 * lisp.h (struct Lisp_Subr.function.aMANY)
19331 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19332 Arg counts are now ptrdiff_t, not size_t.
19333 All variadic functions and their callers changed accordingly.
19334 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19335 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19336 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19337 * callint.c (Fcall_interactively): Check arg count for overflow,
19338 to avoid potential buffer overrun. Use signed char, not 'int',
19339 for 'varies' array, so that we needn't bother to check its size
19340 calculation for overflow.
19341 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19342 * eval.c (apply_lambda):
19343 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19344 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19345 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19347 * callint.c (Fcall_interactively): Don't use index var as event count.
19349 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19350 * mem-limits.h (SIZE): Remove; no longer used.
19352 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19354 Remove unnecessary casts.
19355 * xterm.c (x_term_init):
19356 * xfns.c (x_set_border_pixel):
19357 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19358 These aren't needed now that we assume ANSI C.
19360 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19361 It's more likely to cause problems (due to unsigned overflow)
19364 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19366 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19368 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19370 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19372 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19374 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19376 GLYPH_CODE_FACE returns EMACS_INT, not int.
19377 * dispextern.h (merge_faces):
19378 * xfaces.c (merge_faces):
19379 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19380 Don't assume EMACS_INT fits in int.
19382 * character.h (CHAR_VALID_P): Remove unused parameter.
19383 * fontset.c, lisp.h, xdisp.c: All uses changed.
19385 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19387 * fns.c (concat): Minor tuning based on overflow analysis.
19388 This doesn't fix any bugs. Use int to hold character, instead
19389 of constantly refetching from Emacs object. Use XFASTINT, not
19390 XINT, for value known to be a character. Don't bother comparing
19391 a single byte to 0400, as it's always less.
19393 * floatfns.c (Fexpt):
19394 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19396 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19399 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19401 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19402 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19403 incorrectly succeed when S was a string, because 4294967386 was
19404 truncated before it was used.
19406 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19407 Otherwise, an out-of-range integer could cause undefined behavior
19410 * composite.c: Use int, not EMACS_INT, for characters.
19411 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19412 EMACS_INT, for values that are known to be in character range.
19413 This doesn't fix any bugs but is the usual style inside Emacs and
19414 may generate better code on 32-bit machines.
19416 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19417 This is for reasons similar to the recent CHAR_STRING fix.
19418 * charset.c (Fencode_char): Check that character arg is actually
19419 a character. Pass an int to ENCODE_CHAR.
19420 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19421 wider than 'int', as a compile-time check to prevent future regressions
19424 * character.c (char_string): Remove unnecessary casts.
19426 Make sure a 64-bit char is never passed to CHAR_STRING.
19427 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19428 by silently ignoring the top 32 bits, allowing some values
19429 that were far too large to be valid characters.
19430 * character.h: Include <verify.h>.
19431 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19432 arguments are no wider than unsigned, as a compile-time check
19433 to prevent future regressions in this area.
19435 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19436 (Fsubst_char_in_region):
19438 * xdisp.c (decode_mode_spec_coding):
19439 Adjust to CHAR_STRING's new requirement.
19440 * editfns.c (Finsert_char, Fsubst_char_in_region):
19441 * fns.c (concat): Check that character args are actually
19442 characters. Without this test, these functions did the wrong
19443 thing with wildly out-of-range values on 64-bit hosts.
19445 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19446 These casts should not be needed on 32-bit hosts, either.
19447 * keyboard.c (read_char):
19448 * lread.c (Fload): Remove casts to unsigned.
19450 * lisp.h (UNSIGNED_CMP): New macro.
19451 This fixes comparison bugs on 64-bit hosts.
19452 (ASCII_CHAR_P): Use it.
19453 * casefiddle.c (casify_object):
19454 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19455 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19456 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19457 * dispextern.h (FACE_FROM_ID):
19458 * keyboard.c (read_char): Use UNSIGNED_CMP.
19460 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19461 not to EMACS_INT, to avoid GCC warning.
19463 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19465 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19466 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19467 isn't needed on 32-bit machines.
19469 * buffer.c (Fgenerate_new_buffer_name):
19470 Use EMACS_INT for count, not int.
19471 (advance_to_char_boundary): Return EMACS_INT, not int.
19473 * data.c (Qcompiled_function): Now static.
19475 * window.c (window_body_lines): Now static.
19477 * image.c (gif_load): Rename local to avoid shadowing.
19479 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19480 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19481 * alloc.c (make_save_value): Integer argument is now of type
19482 ptrdiff_t, not int.
19483 (mark_object): Use ptrdiff_t, not int.
19484 * lisp.h (pD): New macro.
19485 * print.c (print_object): Use it.
19487 * alloc.c: Use EMACS_INT, not int, to count objects.
19488 (total_conses, total_markers, total_symbols, total_vector_size)
19489 (total_free_conses, total_free_markers, total_free_symbols)
19490 (total_free_floats, total_floats, total_free_intervals)
19491 (total_intervals, total_strings, total_free_strings):
19492 Now EMACS_INT, not int. All uses changed.
19493 (Fgarbage_collect): Compute overall total using a double, so that
19494 integer overflow is less likely to be a problem. Check for overflow
19495 when converting back to an integer.
19496 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19497 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19498 These were 'int' variables that could overflow on 64-bit hosts;
19499 they were never used, so remove them instead of repairing them.
19500 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19501 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19502 Previously, this ceilinged at INT_MAX, but that doesn't work on
19504 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19506 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19507 (allocate_vectorlike): Check for ptrdiff_t overflow.
19508 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19509 when a (possibly-narrower) signed value would do just as well.
19510 We prefer using signed arithmetic, to avoid comparison confusion.
19512 * alloc.c: Catch some string size overflows that we were missing.
19513 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19514 for convenience in STRING_BYTES_MAX.
19515 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19516 The definition here is exact; the one in lisp.h was approximate.
19517 (allocate_string_data): Check for string overflow. This catches
19518 some instances we weren't catching before. Also, it catches
19519 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19520 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19521 and ptrdiff_t and EMACS_INT are both 64 bits.
19523 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19524 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19525 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19527 * character.c (string_escape_byte8): Fix nbytes/nchars typo.

19973 * keymap.c (access_keymap, silly_event_symbol_error):
19974 XUINT -> XFASTINT, since the integer must be nonnegative.
19975 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
19976 since it makes no difference and we prefer signed.
19977 * keyboard.c (record_char): Use XUINT when all the neighbors do.
19978 (access_keymap): NATNUMP -> INTEGERP, since the integer must be

20025 code. Minor doc-string fixes.
20027 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
20029 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
20030 Do not assume that spare memory exists; that assumption is valid
20031 only if SYSTEM_MALLOC.
20032 (LARGE_REQUEST): New macro, so that the issue of large requests
20033 is separated from the issue of spare memory.
20035 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
20037 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

20063 New error handlers.
20064 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
20065 Obey Vx_select_enable_clipboard_manager. Catch errors in

20089 (bidi_cache_search, bidi_cache_iterator_state)
20090 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
20091 (bidi_level_of_next_char, bidi_move_to_visually_next):
20092 Support character positions inside a run of characters covered by a
20094 (bidi_paragraph_init, bidi_resolve_explicit_1)
20095 (bidi_level_of_next_char): Call bidi_fetch_char and
20096 bidi_fetch_char_advance instead of FETCH_CHAR and

20099 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
20101 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
20102 instead of using explicit *_CHAR codes.
20103 (bidi_resolve_explicit, bidi_resolve_weak):
20104 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
20105 bidirectional text is supported only in multibyte buffers.
20106 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
20107 it to initialize the frame_window_p member of struct bidi_it.

20111 bidi_it->nchars is non-positive.
20112 (bidi_level_of_next_char): Don't try to lookup the cache for the
20113 next/previous character if nothing is cached there yet, or if we
20114 were just reseat()'ed to a new position.
20116 * xdisp.c (set_cursor_from_row): Set start and stop points
20117 according to the row's direction when priming the loop that looks
20118 for the glyph on which to display cursor.
20119 (single_display_spec_intangible_p): Function deleted.
20120 (display_prop_intangible_p): Reimplement to call
20121 handle_display_spec instead of single_display_spec_intangible_p.
20122 Accept 3 additional arguments needed by handle_display_spec.
20123 This fixes incorrect cursor motion across display property with complex
20124 values: lists, `(when COND...)' forms, etc.
20125 (single_display_spec_string_p): Support property values that are
20126 lists with the argument STRING its top-level element.
20127 (display_prop_string_p): Fix the condition for processing a
20128 property that is a list to be consistent with handle_display_spec.

20130 last portion of handle_display_prop.
20131 (compute_display_string_pos): Accept additional argument
20132 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20133 value of a `display' property is a "replacing spec".
20134 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20135 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20136 the display property, but just return a value indicating whether
20137 the display property will replace the characters it covers.
20138 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20139 frame_window_p members of struct bidi_it.
20140 (compute_display_string_pos, compute_display_string_end):
20142 (push_it): Accept second argument POSITION, where pop_it should
20143 jump to continue iteration.
20144 (reseat_1): Initialize bidi_it.disp_pos.
20146 * keyboard.c (adjust_point_for_property): Adjust the call to
20147 display_prop_intangible_p to its new signature.
20149 * dispextern.h (struct bidi_it): New member frame_window_p.
20150 (bidi_init_it): Update prototypes.

20160 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
20161 * lisp.h: Change signatures accordingly.
20162 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
20163 All callers changed. (Bug#8762)
20165 * gnutls.c: Use Emacs's memory allocators.
20166 Without this change, the gnutls library would invoke malloc etc.
20167 directly, which causes problems on non-SYNC_INPUT hosts, and which
20168 runs afoul of improving memory_full behavior. (Bug#8761)
20169 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20170 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20171 xfree instead of the default malloc, realloc, free.
20172 (Fgnutls_boot): No need to check for memory allocation failure,
20173 since xmalloc does that for us.
20175 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
20176 * category.c (hash_get_category_set):
20177 * ccl.c (ccl_driver):

20189 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
20190 (Fsxhash, Fgethash, Fputhash, Fmaphash):
20191 * image.c (make_image, search_image_cache, lookup_image)
20192 (xpm_put_color_table_h):
20193 * lisp.h (struct Lisp_Hash_Table):
20194 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20195 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20196 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20197 * alloc.c (allocate_vectorlike):
20198 Check for overflow in vector size calculations.
20199 * ccl.c (ccl_driver):
20200 Check for overflow when converting EMACS_INT to int.
20201 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20202 need to be updated by these changes.
20203 * fns.c (make_hash_table, maybe_resize_hash_table):
20204 Check for integer overflow with large hash tables.
20205 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20206 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20207 (SXHASH_REDUCE): New macro.
20208 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20209 Use it instead of discarding useful hash info with large hash values.
20210 (sxhash_float): New function.
20211 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20212 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20213 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20214 Rewrite to use FIXNUM_BITS, as this simplifies things.
20215 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20216 Adjust signatures to match updated version of code.
20217 (consing_since_gc): Now EMACS_INT, since a single hash table can
20218 use more than INT_MAX bytes.
20220 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20222 Make it possible to build with GCC-4.6+ -O2 -flto.
20224 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20226 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20228 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20229 Call minibuffer-inactive-mode.
20231 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20233 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20234 Update dependencies.
20236 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20238 * data.c (init_data): Remove code for UTS, this system is not
20241 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20243 Don't force ./temacs to start in terminal mode.
20245 * frame.c (make_initial_frame): Initialize faces in all cases, not
20246 only when CANNOT_DUMP is defined.
20247 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20249 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20251 * dispnew.c (add_window_display_history): Use const for the string
20252 pointer. Remove declaration, not needed.
20254 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20256 Use 'inline', not 'INLINE'.
20257 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20258 * alloc.c, fontset.c (INLINE): Remove.
20259 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20260 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20261 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20262 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20263 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20265 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20267 Make it possible to run ./temacs.
20269 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20270 syms_of_callproc does the same thing. Remove test for
20271 "initialized", do it in the caller.
20272 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20274 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20276 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20277 (read_minibuf): Use get_minibuffer.
20278 (syms_of_minibuf): Use DEFSYM.
20279 (Qmetadata): New var.
20280 * data.c (Qbuffer): Don't make it static.
20281 (syms_of_data): Use DEFSYM.
20283 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20285 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20286 (CCL_CODE_MIN): New macro.
20288 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20290 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20292 * eval.c (Qdebug): Now static.
20293 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20294 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20295 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20297 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20299 * image.c: Various fixes to ImageMagick code comments.
20300 (Fimagemagick_types): Doc fix.
20302 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20304 Minor fixes prompted by GCC 4.6.0 warnings.
20306 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20308 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20309 (x_clipboard_manager_save_all): Move extern decl to ...
20310 * xterm.h: ... here, so that it can be checked for consistency.
20312 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20314 * xselect.c (x_clipboard_manager_save_frame)
20315 (x_clipboard_manager_save_all): New functions.
20316 (Fx_clipboard_manager_save): Lisp function deleted.
20318 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20319 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20321 * xterm.h: Update prototype.
20323 2011-05-28 William Xu <william.xwl@gmail.com>
20325 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20326 exiting (Bug#8239).
20328 2011-05-28 Jim Meyering <meyering@redhat.com>
20330 Avoid a sign-extension bug in crypto_hash_function.
20331 * fns.c (to_uchar): Define.
20332 (crypto_hash_function): Use it to convert some newly-signed
20333 variables to unsigned, to avoid sign-extension bugs. For example,
20334 without this change, (md5 "truc") would evaluate to
20335 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20336 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20337 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20339 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20341 Integer overflow fixes.
20343 * dbusbind.c: Serial number integer overflow fixes.
20344 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20345 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20346 to hold a serial number that is too large for a fixnum.
20347 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20348 Check for serial numbers out of range. Decode any serial number
20349 that was so large that it became a float. (Bug#8722)
20351 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20352 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20353 Use XFASTINT rather than XUINT when numbers are nonnegative.
20354 (xd_append_arg, Fdbus_method_return_internal):
20355 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20356 arguments, check that Lisp number is nonnegative, rather than
20357 silently wrapping negative numbers around. (Bug#8722)
20358 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20361 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20363 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20365 ccl: Add integer overflow checks.
20366 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20367 (IN_INT_RANGE): New macros.
20368 (ccl_driver): Use them to check for integer overflow when
20369 decoding a CCL program. Many of the new checks are whether XINT (x)
20370 fits in int; it doesn't always, on 64-bit hosts. The new version
20371 doesn't catch all possible integer overflows, but it's an
20372 improvement. (Bug#8719)
20374 * alloc.c (make_event_array): Use XINT, not XUINT.
20375 There's no need for unsigned here.
20377 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20378 This follows up to the 2011-05-06 change that substituted uintptr_t
20379 for EMACS_INT. This case wasn't caught back then.
20381 Rework Fformat to avoid integer overflow issues.
20382 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20383 now (part of C89). Include <verify.h>.
20384 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20385 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20386 (Fformat): Avoid the prepass trying to compute sizes; it was only
20387 approximate and thus did not catch overflow reliably. Instead, walk
20388 through the format just once, formatting and computing sizes as we go,
20389 checking for integer overflow at every step, and allocating a larger
20390 buffer as needed. Keep track separately whether the format is
20391 multibyte. Keep only the most-recently calculated precision, rather
20392 than them all. Record whether each argument has been converted to
20393 string. Use EMACS_INT, not int, for byte and char and arg counts.
20394 Support field widths and precisions larger than INT_MAX. Avoid
20395 sprintf's undefined behavior with conversion specifications such as %#d
20396 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20397 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20398 formatting out-of-range floating point numbers with int
20399 formats. (Bug#8668)
20401 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20403 * data.c: Avoid integer truncation in expressions involving floats.
20404 * data.c: Include <intprops.h>.
20405 (arith_driver): When there's an integer overflow in an expression
20406 involving floating point, convert the integers to floating point
20407 so that the resulting value does not suffer from catastrophic
20408 integer truncation. For example, on a 64-bit host (* 4
20409 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20410 Do not rely on undefined behavior after integer overflow.
20412 merge count_size_as_multibyte, parse_str_to_multibyte
20413 * character.c, character.h (count_size_as_multibyte):
20414 Rename from parse_str_to_multibyte; all uses changed.
20415 Check for integer overflow.
20416 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20417 since it's now a duplicate of the other. This is more of
20418 a character than a buffer op, so better that it's in character.c.
20419 * fns.c, print.c: Adjust to above changes.
20421 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20423 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20425 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20427 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20428 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20429 (x_clipboard_manager_save): Now static.
20430 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20432 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20433 (crypto_hash_function): Now static.
20434 Fix pointer signedness problems. Avoid unnecessary initializations.
20436 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20438 * termhooks.h (Vselection_alist): Make it terminal-local.
20440 * terminal.c (create_terminal): Initialize it.
20442 * xselect.c: Support for clipboard managers.
20443 (Vselection_alist): Move to termhooks.h as terminal-local var.
20444 (LOCAL_SELECTION): New macro.
20445 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20446 (symbol_to_x_atom): Remove gratuitous arg.
20447 (x_handle_selection_request, lisp_data_to_selection_data)
20448 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20449 (x_own_selection, x_get_local_selection, x_convert_selection):
20450 New arg, specifying work frame. Use terminal-local Vselection_alist.
20451 (some_frame_on_display): Delete unused function.
20452 (Fx_own_selection_internal, Fx_get_selection_internal)
20453 (Fx_disown_selection_internal, Fx_selection_owner_p)
20454 (Fx_selection_exists_p): New optional frame arg.
20455 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20456 (x_handle_selection_clear): Don't treat other terminals with the
20457 same keyboard specially. Use the terminal-local Vselection_alist.
20458 (x_clear_frame_selections): Use Frun_hook_with_args.
20460 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20462 * xterm.h: Add support for those atoms.
20464 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20466 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20467 (converted_selections, conversion_fail_tag): New global variables.
20468 (x_selection_request_lisp_error): Free the above.
20469 (x_get_local_selection): Remove unnecessary code.
20470 (x_reply_selection_request): Args changed; handle arbitrary array
20471 of converted selections stored in converted_selections.
20472 Separate the XChangeProperty and SelectionNotify steps.
20473 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20474 (x_convert_selection): New function.
20475 (x_handle_selection_event): Simplify.
20476 (x_get_foreign_selection): Don't ignore incoming requests while
20477 waiting for an answer; this will fail when we implement
20478 SAVE_TARGETS, and seems unnecessary anyway.
20479 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20480 (Vx_sent_selection_functions): Doc fix.
20482 2011-05-26 Leo Liu <sdl.web@gmail.com>
20484 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20486 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20488 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20490 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20491 for fringe update if it has periodic bitmap.
20492 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20493 and fringe_bitmap_periodic_p.
20495 * fringe.c (get_fringe_bitmap_data): New function.
20496 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20497 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20498 row. Mark glyph row for fringe update if periodicity changed.
20500 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20501 for fringe update unless it has periodic bitmap.
20503 2011-05-25 Kenichi Handa <handa@m17n.org>
20505 * xdisp.c (get_next_display_element): Set correct it->face_id for
20506 a static composition.
20508 2011-05-24 Leo Liu <sdl.web@gmail.com>
20511 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20513 * fns.c (crypto_hash_function, Fsha1): New function.
20514 (Fmd5): Use crypto_hash_function.
20515 (syms_of_fns): Add Ssha1.
20517 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20519 * gnutls.c: Remove unused macros.
20520 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20521 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20522 Remove macros that are defined and never used.
20523 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20525 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20527 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20528 (Fx_get_selection_internal): Minor cleanup.
20529 (Fx_own_selection_internal): Rename arguments for consistency with
20532 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20534 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20536 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20538 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20540 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20542 * dispnew.c (scrolling_window): Don't exclude the case that the
20543 last enabled row in the desired matrix touches the bottom boundary.
20545 2011-05-21 Glenn Morris <rgm@gnu.org>
20547 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20548 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20549 and add some more files.
20551 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20553 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20554 report_file_error introduced by the change from 2011-05-07.
20556 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20558 * systime.h (Time): Define only if emacs is defined.
20559 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20560 where the include path doesn't have X11/X.h by default. See
20561 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20563 2011-05-20 Kenichi Handa <handa@m17n.org>
20565 * composite.c (find_automatic_composition): Fix previous change.
20567 2011-05-20 Glenn Morris <rgm@gnu.org>
20569 * lisp.mk: New file, split from Makefile.in.
20570 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20571 (shortlisp): Remove.
20572 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20574 2011-05-19 Glenn Morris <rgm@gnu.org>
20576 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20577 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20578 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20579 (lisp): Set the order to that of loadup.el.
20580 (shortlisp): Make it a copy of $lisp.
20581 (SOME_MACHINE_LISP): Remove.
20582 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20583 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20585 2011-05-18 Kenichi Handa <handa@m17n.org>
20587 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20588 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20589 (find_automatic_composition): Mostly rewrite for efficiency.
20591 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20593 * makefile.w32-in: Update dependencies.
20595 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20597 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20598 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20600 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20602 Fix some integer overflow issues, such as string length overflow.
20604 * insdel.c (count_size_as_multibyte): Check for string overflow.
20606 * character.c (lisp_string_width): Check for string overflow.
20607 Use EMACS_INT, not int, for string indexes and lengths; in
20608 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20609 the resulting string length overflows an EMACS_INT; instead,
20610 report a string overflow if no precision given. When checking for
20611 precision exhaustion, use a check that cannot possibly have
20612 integer overflow. (Bug#8675)
20613 * character.h (lisp_string_width): Adjust to new signature.
20615 * alloc.c (string_overflow): New function.
20616 (Fmake_string): Use it. This doesn't change behavior, but saves
20617 a few bytes and will simplify future changes.
20618 * character.c (string_escape_byte8): Likewise.
20619 * lisp.h (string_overflow): New decl.
20621 Fixups, following up to the user-interface timestamp change.
20622 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20623 for UI timestamps, instead of unsigned long.
20624 * msdos.c (mouse_get_pos): Likewise.
20625 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20626 * w32gui.h (Time): Define by including "systime.h" rather than by
20627 declaring it ourselves. (Bug#8664)
20629 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20630 * image.c (clear_image_cache): Likewise.
20632 * term.c (term_mouse_position): Don't assume time_t wraparound.
20634 Be more systematic about user-interface timestamps.
20635 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20636 and sometimes 'EMACS_UINT', to represent these timestamps.
20637 This change causes it to use 'Time' uniformly, as that's what X uses.
20638 This makes the code easier to follow, and makes it easier to catch
20639 integer overflow bugs such as Bug#8664.
20640 * frame.c (Fmouse_position, Fmouse_pixel_position):
20641 Use Time, not unsigned long, for user-interface timestamps.
20642 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20643 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20644 * keyboard.h (last_event_timestamp): Likewise.
20645 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20646 * menu.h (xmenu_show): Likewise.
20647 * term.c (term_mouse_position): Likewise.
20648 * termhooks.h (struct input_event.timestamp): Likewise.
20649 (struct terminal.mouse_position_hook): Likewise.
20650 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20651 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20652 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20653 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20654 what it was before.
20655 * menu.h, termhooks.h: Include "systime.h", for Time.
20657 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20658 Don't assume that the difference between two unsigned long values
20659 can fit into an integer. At this point, we know button_down_time
20660 <= event->timestamp, so the difference must be nonnegative, so
20661 there's no need to cast the result if double-click-time is
20662 nonnegative, as it should be; check that it's nonnegative, just in
20663 case. This bug is triggered when events are more than 2**31 ms
20664 apart (about 25 days). (Bug#8664)
20666 * xselect.c (last_event_timestamp): Remove duplicate decl.
20667 (x_own_selection): Remove needless cast to unsigned long.
20669 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20670 that always fit in int. Use a sentinel instead of a counter, to
20671 avoid a temp and to allay GCC's concerns about possible int overflow.
20672 * frame.h (struct frame): Use int for menu_bar_items_used
20673 instead of EMACS_INT, since it always fits in int.
20675 * menu.c (grow_menu_items): Check for int overflow.
20677 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20679 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20680 Before, the code was not consistent. These values cannot exceed
20681 2**31 - 1 so there's no need to make them unsigned.
20682 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20683 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20684 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20686 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20688 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20689 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20690 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20691 presumably because the widths might not match.
20693 * window.c (size_window): Avoid needless test at loop start.
20695 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20697 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20699 2011-05-12 Drew Adams <drew.adams@oracle.com>
20701 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20703 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20705 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20706 `width' to `bar_area_x' and `bar_area_width', respectively.
20707 (x_scroll_run): Take account of fringe background extension.
20709 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20710 Rename local vars `left' and `width' to `bar_area_x' and
20711 `bar_area_width', respectively.
20712 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20713 background extension.
20715 2011-05-10 Jim Meyering <meyering@redhat.com>
20717 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20719 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20721 * image.c (Finit_image_library): Return t for built-in image types,
20722 like pbm and xbm. (Bug#8640)
20724 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20726 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20728 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20730 * w32console.c (Fset_screen_color): Doc fix.
20731 (Fget_screen_color): New function.
20732 (syms_of_ntterm): Defsubr it.
20734 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20735 unlink the temporary file if Fcall_process didn't create it in the
20737 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20738 child process will be redirected to a file specified with `:file'.
20739 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20740 cue to call_process_cleanup not to close that handle.
20742 2011-05-07 Ben Key <bkey76@gmail.com>
20744 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20745 one of two shell specific rules, either bootstrap-temacs-CMD or
20746 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20747 to the previous implementation of the bootstrap-temacs rule.
20748 The bootstrap-temacs-CMD rule is similar to the previous
20749 implementation of the bootstrap-temacs rule except that it
20750 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20753 These changes, along with some changes to nt/configure.bat,
20754 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20755 earlier fix to add support for --cflags and --ldflags options
20756 that include quotes so that it works whether make uses cmd or
20759 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20761 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20762 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20764 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20765 a string. Handle both cases.
20766 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20767 (Fdbus_register_method): Use Qinvalid_function.
20769 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20771 * makefile.w32-in: Update dependencies.
20772 (LISP_H): Add inttypes.h and stdin.h.
20773 (PROCESS_H): Add unistd.h.
20775 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20777 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20778 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20780 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20782 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20784 * term.c (vfatal): Remove stray call to va_end.
20785 It's not needed and the C Standard doesn't allow it here anyway.
20787 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20788 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20790 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20793 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20795 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20797 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20799 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20801 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20803 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20804 * charset.c (Fdefine_charset_internal): Don't initialize
20805 charset.code_space[15]. The value was garbage, on hosts with
20806 32-bit int (Bug#8600).
20808 * lread.c (read_integer): Be more consistent with string-to-number.
20809 Use string_to_number to do the actual conversion; this avoids
20810 rounding errors and fixes some other screwups. Without this fix,
20811 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20812 (digit_to_number): Move earlier, for benefit of read_integer.
20813 Return -1 if the digit is out of range for the base, -2 if it is
20814 not a digit in any supported base. (Bug#8602)
20816 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20818 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20819 to match comment at start of function. This also removes a
20820 GCC warning about overflow in a 32+64-bit port.
20822 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20824 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20825 Reported by Stefan Monnier in
20826 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20827 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20828 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20830 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20831 (EMACS_UINTPTR): Likewise, with uintptr_t.
20833 * lisp.h: Prefer 64-bit EMACS_INT if available.
20834 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20835 on 32-bit hosts that have 64-bit int, so that they can access
20837 However, temporarily disable this change unless the temporary
20838 symbol WIDE_EMACS_INT is defined.
20840 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20842 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20843 This removes an assumption that EMACS_INT and long are the same
20844 width as pointers. The assumption is true for Emacs porting targets
20845 now, but we want to make other targets possible.
20846 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20847 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20848 In the rest of the code, change types of integers that hold casted
20849 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20850 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20851 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20852 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20853 No need to cast type when ORing.
20854 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20855 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20856 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20857 assume EMACS_INT is the same width as char *.
20858 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20859 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20860 Remove no-longer-needed casts.
20861 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20862 (xg_tool_bar_help_callback, xg_make_tool_item):
20863 Use EMACS_INTPTR to hold an integer
20864 that will be cast to void *; this can avoid a GCC warning
20865 if EMACS_INT is not the same width as void *.
20866 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20867 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20868 (current_message_1, set_message_1):
20869 Use a local to convert to proper width without a cast.
20870 * xmenu.c (dialog_selection_callback): Likewise.
20872 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20873 Also, don't assume VALBITS / RAND_BITS is less than 5,
20874 and don't rely on undefined behavior when shifting a 1 left into
20876 * lisp.h (get_random): Change signature to match.
20878 * lread.c (hash_string): Use size_t, not int, for hash computation.
20879 Normally we prefer signed values; but hashing is special, because
20880 it's better to use unsigned division on hash table sizes so that
20881 the remainder is nonnegative. Also, size_t is the natural width
20882 for hashing into memory. The previous code used 'int', which doesn't
20883 retain enough info to hash well into very large tables.
20884 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20886 * dbusbind.c: Don't possibly lose pointer info when converting.
20887 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20888 Use XPNTR rather than XHASH, so that the high-order bits of
20889 the pointer aren't lost when converting through void *.
20891 * eval.c (Fautoload): Don't double-shift a pointer.
20893 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20895 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20897 * gnutls.c (DEF_GNUTLS_FN):
20898 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20900 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20902 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20905 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20907 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20908 New version that can reserve upto 2GB of heap space.
20910 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
20912 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
20914 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
20916 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20917 `gnutls_certificate_set_x509_key_file'.
20919 2011-05-05 Juanma Barranquero <lekktu@gmail.com>

20922 Update dependencies.
20924 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20926 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20927 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20928 Remove unused parameter `fildes'.
20929 * process.c (read_process_output, send_process): Don't pass it.
20931 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20933 Fix previous change: the library cache is defined in w32.c.
20934 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20935 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20937 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20939 Implement dynamic loading of GnuTLS on Windows.
20941 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20942 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20943 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
20946 * gnutls.c (Qgnutls_dll): Define.

20955 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20956 (Fgnutls_available_p): New function.
20957 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

20967 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20969 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20970 (w32_delayed_load): Move from image.c. When loading a library, record
20971 its filename in the :loaded-from property of the library id.
20972 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20973 Initialize and staticpro them.
20974 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20976 * process.c: Include lisp.h before w32.h, not after.
20977 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20978 instead of gnutls_record_check_pending.
20980 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20982 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20984 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20985 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20988 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20990 * xterm.c (x_set_frame_alpha): Do not set property on anything
20991 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20993 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20995 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20997 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20999 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
21000 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

21015 Move after wait_for_termination_1.
21017 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
21019 * sysdep.c (interruptible_wait_for_termination): New function
21020 which is like wait_for_termination, but allows keyboard
21023 * callproc.c (Fcall_process): Add (:file "file") as an option for
21025 (Fcall_process_region): Ditto.
21027 2011-04-30 Eli Zaretskii <eliz@gnu.org>
21029 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
21030 rather than `XVECTOR (FOO)->size'.
21032 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
21033 inttypes.h, as a gnulib replacement is used if it not available in
21036 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21038 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
21039 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
21040 of MOST_POSITIVE_FIXNUM. (Bug#8528)
21042 * coding.c (coding_alloc_by_realloc): Error out if destination
21043 will grow beyond MOST_POSITIVE_FIXNUM.
21044 (decode_coding_emacs_mule): Abort if there isn't enough place in
21045 charbuf for the composition carryover bytes. Reserve an extra
21046 space for up to 2 characters produced in a loop.
21047 (decode_coding_iso_2022): Abort if there isn't enough place in
21048 charbuf for the composition carryover bytes.
21050 2011-04-21 Eli Zaretskii <eliz@gnu.org>
21052 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
21053 aborting when %lld or %lll format is passed.
21054 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
21055 %llo or %llx format is passed. (Bug#8545)
21057 * window.c (window_scroll_line_based): Use a marker instead of
21058 simple variables to record original value of point. (Bug#7952)
21060 * doprnt.c (doprnt): Fix the case where a multibyte sequence
21061 produced by %s or %c overflows available buffer space. (Bug#8545)
21063 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21065 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21066 (SIZE_MAX): Move defn after all includes, as they might #define it.
21068 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21070 * w32.c (init_environment): Warn about defaulting HOME to C:\.

21074 * keyboard.c (Qdelayed_warnings_hook): Define.
21075 (command_loop_1): Run `delayed-warnings-hook'
21076 if Vdelayed_warnings_list is non-nil.
21077 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21078 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21080 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21082 * doprnt.c (doprnt): Don't return value smaller than the buffer
21083 size if the message was truncated. (Bug#8545).
21085 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21087 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21088 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21090 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21092 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21094 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21096 * makefile.w32-in: Update dependencies.
21098 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21100 Improve `doprnt' and its usage. (Bug#8545)
21101 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21102 `format_end'. Remove support for %l as a conversion specifier.
21103 Don't use xrealloc. Improve diagnostics when the %l size modifier
21104 is used. Update the commentary.
21106 * eval.c (verror): Simplify calculation of size_t.
21108 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21111 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21113 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21116 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21118 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21119 This makes this file independent of the recent pseudovector change.
21121 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21123 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21125 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21126 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21127 Remove unused local.
21128 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21130 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21131 GCC 4.6.0 optimizes based on type-based alias analysis.
21132 For example, if b is of type struct buffer * and v of type struct
21133 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21134 != &v->size, and therefore "v->size = 1; b->size = 2; return
21135 v->size;" must therefore return 1. This assumption is incorrect
21136 for Emacs, since it type-puns struct Lisp_Vector * with many other
21137 types. To fix this problem, this patch adds a new type struct
21138 vectorlike_header that documents the constraints on layout of vectors
21139 and pseudovectors, and helps optimizing compilers not get fooled
21140 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21141 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21142 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21144 (XSETPVECTYPE): Rewrite in terms of new macro.
21145 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21146 This is a bit clearer, and further avoids the possibility of
21147 undesirable aliasing.
21148 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21149 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21150 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21151 since Lisp_Subr is a special case (no "next" field).
21152 (ASIZE): Now uses header.size rather than size.
21153 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21154 to avoid the hassle of writing XVECTOR (foo)->header.size.
21155 (struct vectorlike_header): New type.
21156 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21157 object, to help avoid aliasing.
21158 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21159 (SUBRP): Likewise, since Lisp_Subr is a special case.
21160 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21161 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21162 (struct Lisp_Hash_Table): Combine first two members into a single
21163 struct vectorlike_header member. All uses of "size" and "next" members
21164 changed to be "header.size" and "header.next".
21165 * buffer.h (struct buffer): Likewise.
21166 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21167 * frame.h (struct frame): Likewise.
21168 * process.h (struct Lisp_Process): Likewise.
21169 * termhooks.h (struct terminal): Likewise.
21170 * window.c (struct save_window_data, struct saved_window): Likewise.
21171 * window.h (struct window): Likewise.
21172 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21173 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21174 * buffer.c (init_buffer_once): Likewise.
21175 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21177 * process.c (Fformat_network_address): Use local var for size,
21180 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21182 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21183 * data.c (atof): Remove decl; no longer used or needed.
21184 (digit_to_number): Move to lread.c.
21185 (Fstring_to_number): Use new string_to_number function, to be
21186 consistent with how the Lisp reader treats infinities and NaNs.
21187 Do not assume that floating-point numbers represent EMACS_INT
21188 without losing information; this is not true on most 64-bit hosts.
21189 Avoid double-rounding errors, by insisting on integers when
21190 parsing non-base-10 numbers, as the documentation specifies.
21191 * lisp.h (string_to_number): New decl, replacing ...
21192 (isfloat_string): Remove.
21193 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21194 (read1): Do not accept +. and -. as integers; this
21195 appears to have been a coding error. Similarly, do not accept
21196 strings like +-1e0 as floating point numbers. Do not report
21197 overflow for integer overflows unless the base is not 10 which
21198 means we have no simple and reliable way to continue.
21199 Break out the floating-point parsing into a new
21200 function string_to_number, so that Fstring_to_number parses
21201 floating point numbers consistently with the Lisp reader.
21202 (digit_to_number): Move here from data.c. Make it static inline.
21203 (E_CHAR, EXP_INT): Remove, replacing with ...
21204 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21205 (string_to_number): New function, replacing isfloat_string.
21206 This function checks for valid syntax and produces the resulting
21207 Lisp float number too. Rework it so that string-to-number
21208 no longer mishandles examples like "1.0e+". Use strtoumax,
21209 so that overflow for non-base-10 numbers is reported only when
21210 there's no portable and simple way to convert to floating point.
21212 * textprop.c (set_text_properties_1): Rewrite for clarity,
21213 and to avoid GCC warning about integer overflow.
21215 * intervals.h (struct interval): Use EMACS_INT for members
21216 where EMACS_UINT might cause problems. See
21217 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21218 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21219 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21221 (offset_intervals): Tell GCC not to worry about length overflow
21222 when negating a negative length.
21224 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21225 (overrun_check_free): Likewise.
21227 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21228 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21231 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21232 (gnutls_make_error): Rename local to avoid shadowing.
21233 (gnutls_emacs_global_deinit): ifdef out; not used.
21234 (Fgnutls_boot): Use const for pointer to readonly storage.
21235 Comment out unused local. Fix pointer signedness problems.
21237 * lread.c (openp): Don't stuff size_t into an 'int'.
21238 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21239 about possible signed overflow.
21241 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21242 (GDK_KEY_g): Don't define if already defined.
21243 (xg_prepare_tooltip): Avoid pointer signedness problem.
21244 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21246 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21247 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21249 * xfns.c (Fx_window_property): Simplify a bit,
21250 to make a bit faster and to avoid GCC 4.6.0 warning.
21251 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21253 * fns.c (internal_equal): Don't assume size_t fits in int.
21255 * alloc.c (compact_small_strings): Tighten assertion a little.
21257 Replace pEd with more-general pI, and fix some printf arg casts.
21258 * lisp.h (pI): New macro, generalizing old pEd macro to other
21259 conversion specifiers. For example, use "...%"pI"d..." rather
21260 than "...%"pEd"...".
21261 (pEd): Remove. All uses replaced with similar uses of pI.
21262 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21263 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21264 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21265 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21266 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21267 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21268 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21270 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21271 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21272 * print.c (safe_debug_print, print_object): Likewise.
21273 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21275 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21276 avoiding the 0 flag, which is not portable.
21277 * process.c (Fmake_network_process): Use pI to avoid cast.
21278 * region-cache.c (pp_cache): Likewise.
21279 * xdisp.c (decode_mode_spec): Likewise.
21280 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21281 behavior on 64-bit hosts with printf arg.
21282 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21283 (x_stop_queuing_selection_requests): Likewise.
21284 (x_get_window_property): Don't truncate byte count to an 'int'
21287 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21288 here, since it parses constructs like leading '-' and spaces,
21289 which are not wanted; and it overflows with large numbers.
21290 Instead, simply match F[0-9]+, which is what is wanted anyway.
21292 * alloc.c: Remove unportable assumptions about struct layout.
21293 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21294 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21295 (allocate_vectorlike, make_pure_vector): Use the new macros,
21296 plus offsetof, to remove unportable assumptions about struct layout.
21297 These assumptions hold on all porting targets that I know of, but
21298 they are not guaranteed, they're easy to remove, and removing them
21299 makes further changes easier.
21301 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21302 This doesn't fix a bug but makes the code clearer.
21303 (string_overrun_cookie): Now const. Use initializers that
21304 don't formally overflow signed char, to avoid warnings.
21305 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21306 can cause Emacs to crash when string overrun checking is enabled.
21307 (allocate_buffer): Don't assume sizeof (struct buffer) is a
21308 multiple of sizeof (EMACS_INT); it need not be, if
21309 alignof(EMACS_INT) < sizeof (EMACS_INT).
21310 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
21312 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

21341 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
21342 "cast to pointer from integer of different size".
21344 Improve doprnt and its use in verror. (Bug#8545)
21345 * doprnt.c (doprnt): Document the set of format control sequences
21346 supported by the function. Use SAFE_ALLOCA instead of always
21349 * eval.c (verror): Don't limit the buffer size at size_max-1, that
21350 is one byte too soon. Don't use xrealloc; instead xfree and
21353 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
21355 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

21359 gnutls_global_initialized. Added internals for the
21360 :verify-hostname-error, :verify-error, and :verify-flags
21361 parameters of `gnutls-boot' and documented those parameters in the
21362 docstring. Start callback support.
21363 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
21364 unless a fatal error occurred. Call gnutls_alert_send_appropriate

21462 * callint.c (Fcall_interactively): When displaying error message
21463 about invalid control letter, pass the character's codepoint, not

21468 codepoint of an invalid character, to avoid displaying a bogus
21471 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21472 `error', not SYMBOL_NAME itself.
21474 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

21477 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21478 to `error' in error message about FINAL_CHAR argument. Make sure
21479 FINAL_CHAR is a character, and use %c when it is passed as
21480 argument to `error'.
21482 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21484 * s/ms-w32.h (localtime): Redirect to sys_localtime.
21486 * w32.c: Include <time.h>.

21546 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
21547 by pacifying GCC about it. Maybe it's time to retire it?
21548 * xfaces.c (USG, __TIMEVAL__): Likewise.
21550 * dispextern.h (struct redisplay_interface): Rename param
21551 to avoid shadowing.
21552 * termhooks.h (struct terminal): Likewise.

21669 * nsfont.m: Fixed bugs in ns_get_family and
21670 ns_descriptor_to_entity that were caused by using free to
21671 deallocate memory blocks that were allocated by xmalloc (via
21672 xstrdup). This caused Emacs to crash when compiled with
21673 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21674 --enable-checking=xmallocoverrun). xfree is now used to
21675 deallocate these memory blocks.
21677 2011-04-15 Paul Eggert <eggert@cs.ucla.edu>
21679 * sysdep.c (emacs_read): Remove unnecessary check vs MAX_RW_COUNT.

21689 (emacs_read, emacs_write): Remove check for negative size, as the
21690 Emacs source code has been audited now.
21691 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
21692 (emacs_read, emacs_write): Use it.
21693 * process.c (send_process): Adjust to the new signatures of
21694 emacs_write and emacs_gnutls_write. Do not attempt to store
21695 a byte offset into an 'int'; it might overflow.
21696 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

21722 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>
21724 Improve C-level modularity by making more things 'static'.
21726 Don't publish debugger-only interfaces to other modules.
21727 * lisp.h (safe_debug_print, debug_output_compilation_hack):

22136 * editfns.c (Fformat): Remove unreachable code.
22138 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
22140 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
22143 2011-04-13 Eli Zaretskii <eliz@gnu.org>
22145 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
22146 when at ZV. (Bug#8487)
22148 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
22150 * charset.c (Fclear_charset_maps): Use xfree instead of free.
22152 * keyboard.c (parse_tool_bar_item): Likewise.
22153 * sound.c (sound_cleanup, alsa_close): Likewise.
22154 * termcap.c (tgetent): Likewise.
22155 * xfns.c (x_default_font_parameter): Likewise.
22156 * xsettings.c (read_and_apply_settings): Likewise.
22158 * alloc.c (overrun_check_malloc, overrun_check_realloc)
22159 (overrun_check_free): Protoize.
22161 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
22163 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
22164 since callers should never pass a negative size.
22165 Change the signature to match that of plain 'read' and 'write'; see
22166 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
22167 * lisp.h: Update prototypes of emacs_write and emacs_read.
22169 2011-04-11 Eli Zaretskii <eliz@gnu.org>
22171 * xdisp.c (redisplay_window): Don't try to determine the character
22172 position of the scroll margin if the window start point w->startp
22173 is outside the buffer's accessible region. (Bug#8468)
22175 2011-04-10 Eli Zaretskii <eliz@gnu.org>
22177 Fix write-region and its subroutines for buffers > 2GB.
22178 * fileio.c (a_write, e_write): Modify declaration of arguments and
22179 local variables to support buffers larger than 2GB.
22180 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
22182 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
22183 argument, local variables, and return value.
22185 * lisp.h: Update prototypes of emacs_write and emacs_read.
22187 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
22189 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
22191 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
22193 Fix more problems found by GCC 4.6.0's static checks.
22195 * xdisp.c (vmessage): Use a better test for character truncation.
22197 * charset.c (load_charset_map): <, not <=, for optimization,
22198 and to avoid potential problems with integer overflow.
22199 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
22200 * casetab.c (set_identity, shuffle): Likewise.
22201 * editfns.c (Fformat): Likewise.
22202 * syntax.c (skip_chars): Likewise.
22204 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22205 This also lets GCC 4.6.0 generate slightly better loop code.
22207 * callint.c (Fcall_interactively): <, not <=, for optimization.
22208 (Fcall_interactively): Count the number of arguments produced,
22209 not the number of arguments given. This is simpler and lets GCC
22210 4.6.0 generate slightly better code.
22212 * ftfont.c: Distingish more carefully between FcChar8 and char.
22213 The previous code passed unsigned char * to a functions like
22214 strlen and xstrcasecmp that expect char *, which does not
22215 conform to the C standard.
22216 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22217 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22218 char * when the C standard requires it.
22220 * keyboard.c (read_char): Remove unused var.
22222 * eval.c: Port to Windows vsnprintf (Bug#8435).
22223 Include <limits.h>.
22224 (SIZE_MAX): Define if the headers do not.
22225 (verror): Do not give up if vsnprintf returns a negative count.
22226 Instead, grow the buffer. This ports to Windows vsnprintf, which
22227 does not conform to C99. Problem reported by Eli Zaretskii.
22228 Also, simplify the allocation scheme, by avoiding the need for
22229 calling realloc, and removing the ALLOCATED variable.
22231 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22233 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22234 But keep the doprint source code for now, as we might revamp it
22235 and use it again (Bug#8435).
22236 * lisp.h (doprnt): Remove.
22237 * Makefile.in (base_obj): Remove doprnt.o.
22238 * deps.mk (doprnt.o): Remove.
22240 error: Print 32- and 64-bit integers portably (Bug#8435).
22241 Without this change, on typical 64-bit hosts error ("...%d...", N)
22242 was used to print both 32- and 64-bit integers N, which relied on
22243 undefined behavior.
22244 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22245 * lisp.h (error, verror): Mark as printf-like functions.
22246 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22247 Report overflow in size calculations when allocating printf buffer.
22248 Do not truncate output string at its first null byte.
22249 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22250 Truncate the output at a character boundary, since vsnprintf does not
22252 * charset.c (check_iso_charset_parameter): Convert internal
22253 character to string before calling 'error', since %c now has the
22255 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22256 overflow when computing char to be passed to 'error'. Do not
22257 pass Lisp_Object to 'error'; pass the integer instead.
22258 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22259 formatted with plain %d.
22261 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22263 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22265 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22267 * xterm.c (x_catch_errors): Remove duplicate declaration.
22269 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22271 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22273 2011-04-10 Jim Meyering <meyering@redhat.com>
22275 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22276 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22277 return ssize_t not "int", and use size_t as the buffer length.
22278 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22279 * gnutls.h: Update declarations.
22280 * process.c (read_process_output): Use ssize_t, to match.
22281 (send_process): Likewise.
22283 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22285 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22287 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22289 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22290 Use unsigned char, to match FcChar8 type definition.
22292 * xterm.c (handle_one_xevent):
22293 * xmenu.c (create_and_show_popup_menu):
22294 * xselect.c (x_decline_selection_request)
22295 (x_reply_selection_request): Avoid type-punned deref of X events.
22297 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22299 Fix some uses of `int' instead of EMACS_INT.
22300 * search.c (string_match_1, fast_string_match)
22301 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22302 (scan_buffer, find_next_newline_no_quit)
22303 (find_before_next_newline, search_command, Freplace_match)
22304 (Fmatch_data): Make some `int' variables be EMACS_INT.
22306 * xdisp.c (display_count_lines): 3rd argument and return value now
22307 EMACS_INT. All callers changed.
22308 (pint2hrstr): Last argument is now EMACS_INT.
22310 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22311 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22312 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22313 (decode_coding_utf_16, decode_coding_emacs_mule)
22314 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
22315 (decode_coding_ccl, decode_coding_charset)
22316 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22317 (decode_coding_iso_2022, decode_coding_emacs_mule)
22318 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22319 <char_offset, last_offset>: Declare EMACS_INT.
22320 (encode_coding_utf_8, encode_coding_utf_16)
22321 (encode_coding_emacs_mule, encode_invocation_designation)
22322 (encode_designation_at_bol, encode_coding_iso_2022)
22323 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22324 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22326 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22327 (encode_invocation_designation): Last argument P_NCHARS is now
22329 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22330 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22332 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22335 * ccl.c (Fccl_execute_on_string): Declare some variables
22338 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22340 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22342 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22344 * process.c (Fformat_network_address): Doc fix.
22346 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22348 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22350 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22352 * keyboard.c (read_char): Call Lisp function help-form-show,
22353 instead of using internal_with_output_to_temp_buffer.
22354 (Qhelp_form_show): New var.
22355 (syms_of_keyboard): Use DEFSYM macro.
22357 * print.c (internal_with_output_to_temp_buffer): Function deleted.
22359 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
22361 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22363 * process.c (Flist_processes): Remove to Lisp.
22364 (list_processes_1): Delete.
22366 2011-04-06 Eli Zaretskii <eliz@gnu.org>
22368 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22370 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22372 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22374 Fix more problems found by GCC 4.6.0's static checks.
22376 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22378 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22380 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22382 * xdisp.c (vmessage): Mark as a printf-like function.
22384 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22386 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22388 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22389 printf-like functions.
22390 (tiff_load): Add casts to remove these marks before passing them
22391 to system-supplied API.
22393 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22395 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22396 This avoids several warnings with gcc -Wstrict-overflow.
22397 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22398 directly, rather than having caller test rule sign. This avoids
22399 some unnecessary tests.
22400 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22401 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22402 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22404 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22405 (xfont_open): Avoid unnecessary tests.
22407 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22409 * composite.h, composite.c (composition_gstring_put_cache):
22410 Use EMACS_INT, not int, for length.

22413 breaking out part of COMPOSITION_DECODE_RULE.
22414 (COMPOSITION_DECODE_RULE): Use it.
22415 * composite.c (get_composition_id): Remove unused local vars,
22416 by using the new macro.
22418 * textprop.c (set_text_properties_1): Change while to do-while,
22419 since the condition is always true at first.
22421 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22422 (interval_deletion_adjustment): Return unsigned value.
22425 * process.c (list_processes_1, create_pty, read_process_output):
22426 (exec_sentinel): Remove vars that were set but not used.
22427 (create_pty): Remove unnecessary "volatile"s.
22428 (Fnetwork_interface_info): Avoid possibility of int overflow.

22435 (update_syntax_table): Use unsigned instead of int.
22437 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22438 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22439 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22441 * print.c (print_error_message): Avoid int overflow.
22443 * font.c (font_list_entities): Redo for clarity,
22444 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22446 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22447 (font_score): Avoid potential overflow in diff calculation.
22449 * fns.c (substring_both): Remove var that is set but not used.
22450 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22452 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22454 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22455 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22456 can always succeed if overflow has undefined behavior.
22458 * search.c (boyer_moore, wordify): Remove vars set but not used.
22459 (wordify): Omit three unnecessary tests.
22461 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22462 All callers changed. This avoids the need for an unused var.
22464 * casefiddle.c (casify_region): Remove var that is set but not used.
22466 * dired.c (file_name_completion): Remove var that is set but not used.
22468 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22470 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22471 (Finsert_file_contents): Remove unnecessary code checking fd.
22473 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22474 Check for integer overflow on size calculations.
22476 * buffer.c (Fprevious_overlay_change): Remove var that is set
22479 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22480 Remove vars that are set but not used.
22481 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22482 (timer_check_2): Mark vars as initialized.
22484 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22486 * image.c (lookup_image): Remove var that is set but not used.
22487 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22489 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22490 that are set but not used.
22492 * xfns.c (make_invisible_cursor): Don't return garbage
22493 if XCreateBitmapFromData fails (Bug#8410).
22495 * xselect.c (x_get_local_selection, x_handle_property_notify):
22496 Remove vars that are set but not used.
22498 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22499 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

22508 (map_tty_color) [!defined MSDOS]: Likewise.
22510 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22512 * coding.c: Remove vars that are set but not used.
22513 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22514 All callers changed.
22515 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22516 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22517 (decode_coding_charset): Remove vars that are set but not used.
22519 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22520 that is set but not used.
22522 * print.c (print_object): Remove var that is set but not used.
22524 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22525 The gnulib version avoids calling malloc in the usual case,
22526 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22527 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22528 * filelock.c (current_lock_owner): Likewise.
22529 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22530 * sysdep.c: Include allocator.h, careadlinkat.h.
22531 (emacs_no_realloc_allocator): New static constant.
22532 (emacs_readlink): New function.
22533 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22534 ../lib/careadlinkat.h.
22536 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22538 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22539 first non-nil return value).
22541 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
22543 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22544 if not defined (Bug#8403).

22548 * xdisp.c (display_count_lines): Remove parameter `start',
22549 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

22553 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22554 and thereabouts. All callers changed.
22555 (get_per_char_metric): Remove parameter `f', unused since
22556 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22560 do not dereference NULL upon failed strdup
22561 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22562 (ns_get_family): Likewise.
22564 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22566 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.

22595 * image.c (parse_image_spec): Use Ffunctionp.
22597 * fns.c (concat, mapcar1): Accept byte-code-functions.
22599 * eval.c (Fsetq): Handle lexical vars.
22600 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22601 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22602 (FletX, Flet): Obey lexical binding.
22603 (Fcommandp): Handle closures.
22604 (Feval): New `lexical' arg.
22605 (eval_sub): New function extracted from Feval. Use it almost
22606 everywhere where Feval was used. Look up vars in lexical env.
22608 (Ffunctionp): Move from subr.el.
22609 (Ffuncall): Handle closures.
22610 (apply_lambda): Remove `eval_flags'.
22611 (funcall_lambda): Handle closures and new byte-code-functions.
22612 (Fspecial_variable_p): New function.
22613 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22614 but without exporting it to Lisp.
22616 * doc.c (Fdocumentation, store_function_docstring):
22617 * data.c (Finteractive_form): Handle closures.
22619 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22622 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22624 (exec_byte_code): New function extracted from Fbyte_code to handle new
22625 calling convention for byte-code-functions. Add new byte-codes.
22627 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22629 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22631 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22633 * xdisp.c (redisplay_internal): Fix prototype.
22635 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22637 * xdisp.c (SCROLL_LIMIT): New macro.
22638 (try_scrolling): Use it when setting scroll_limit.
22639 Limit scrolling to 100 screen lines.
22640 (redisplay_window): Even when falling back on "recentering",
22641 position point in the window according to scroll-conservatively,
22642 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22644 (try_scrolling): When point is above the window, allow searching
22645 as far as scroll_max, or one screenful, to compute vertical
22646 distance from PT to the scroll margin position. This prevents
22647 try_scrolling from unnecessarily failing when
22648 scroll-conservatively is set to a value slightly larger than the
22649 window height. Clean up the case of PT below the margin at bottom
22650 of window: scroll_max can no longer be INT_MAX. When aggressive
22651 scrolling is in use, don't let point enter the opposite scroll
22652 margin as result of the scroll.
22653 (syms_of_xdisp) <scroll-conservatively>: Document the
22654 threshold of 100 lines for never-recentering scrolling.
22656 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22658 * dispextern.h (move_it_by_lines):
22659 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22660 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22661 (message_log_check_duplicate): Remove parameters `prev_bol' and
22662 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22663 (redisplay_internal): Remove parameter `preserve_echo_area',
22664 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22666 * indent.c (Fvertical_motion):
22667 * window.c (window_scroll_pixel_based, Frecenter):
22668 Don't pass `need_y_p' to `move_it_by_lines'.
22670 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22672 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22673 steal a few bits to be more compact.
22674 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22675 Remove unneeded casts.
22677 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22679 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22681 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22682 binding" message (bug#7967).
22684 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22686 Fix more problems found by GCC 4.6.0's static checks.
22688 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22689 Remove unused local var.
22691 * editfns.c (Fmessage_box): Remove unused local var.
22693 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22694 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22695 Omit unused local vars.
22696 * window.c (shrink_windows): Omit unused local var.
22697 * menu.c (digest_single_submenu): Omit unused local var.
22698 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22699 Omit unused local var.
22701 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22702 Don't assume string length fits in int.
22703 (keyremap_step, read_key_sequence): Use size_t for sizes.
22704 (read_key_sequence): Don't check last_real_key_start redundantly.
22706 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22707 instead of alloca (Bug#8344).
22709 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22710 (Fbacktrace_frame): Don't assume nframes fits in int.
22712 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22714 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22717 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22719 * cm.c (calccost): Turn while-do into do-while, for clarity.
22721 * keyboard.c (syms_of_keyboard): Use the same style as later
22722 in this function when indexing through an array. This also
22723 works around GCC bug 48267.
22725 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22727 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22729 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22730 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22732 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22733 This avoids undefined behavior on integer overflow, and is a bit
22734 more convenient anyway since it is compared to a size_t variable.
22736 Variadic C functions now count arguments with size_t, not int.
22737 This avoids an unnecessary limitation on 64-bit machines, which
22738 caused (substring ...) to crash on large vectors (Bug#8344).
22739 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22740 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22741 All variadic functions and their callers changed accordingly.
22742 (struct gcpro.nvars): Now size_t, not int. All uses changed.
22743 * data.c (arith_driver, float_arith_driver): Likewise.
22744 * editfns.c (general_insert_function): Likewise.
22745 * eval.c (struct backtrace.nargs, interactive_p)
22746 (internal_condition_case_n, run_hook_with_args, apply_lambda)
22747 (funcall_lambda, mark_backtrace): Likewise.
22748 * fns.c (concat): Likewise.
22749 * frame.c (x_set_frame_parameters): Likewise.
22750 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22751 0 if not found, not -1. All callers changed.
22753 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22754 (stack_copy_size): Now size_t, not int.
22755 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22757 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22759 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22760 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22761 All callers changed.
22763 * lisp.h (multibyte_char_to_unibyte):
22764 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22765 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22766 * character.h (CHAR_TO_BYTE8):
22767 * cmds.c (internal_self_insert):
22768 * editfns.c (general_insert_function):
22769 * keymap.c (push_key_description):
22770 * search.c (Freplace_match):
22771 * xdisp.c (message_dolog, set_message_1): All callers changed.
22773 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
22775 * keyboard.c (safe_run_hook_funcall): New function.
22776 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22777 don't set the hook to nil, but remove the offending function instead.
22778 (Qcommand_hook_internal): Remove, unused.
22779 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22780 Vcommand_hook_internal.
22782 * eval.c (enum run_hooks_condition): Remove.
22783 (funcall_nil, funcall_not): New functions.
22784 (run_hook_with_args): Call each function through a `funcall' argument.
22785 Remove `cond' argument, now redundant.
22786 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
22787 (Frun_hook_with_args_until_failure): Adjust accordingly.
22788 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
22790 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22792 * dispextern.h (string_buffer_position): Remove declaration.
22794 * print.c (strout): Remove parameter `multibyte', unused since
22795 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
22797 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
22798 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22799 All callers changed.
22801 * w32.c (_wsa_errlist): Use braces for struct initializers.
22803 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
22804 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
22805 All callers changed.
22806 (string_buffer_position): Likewise. Also, make static (it's never
22807 used outside xdisp.c).
22808 (cursor_row_p): Remove parameter `w', unused since
22809 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

22811 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
22812 All callers changed.
22814 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22816 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
22818 2011-03-27 Anders Lindgren <andlind@gmail.com>
22820 * nsterm.m (ns_menu_bar_is_hidden): New variable.
22821 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
22822 (ns_update_auto_hide_menu_bar): New functions.
22823 (ns_update_begin): Call ns_update_auto_hide_menu_bar.
22824 (applicationDidBecomeActive): Call ns_update_auto_hide_menu_bar and
22825 ns_constrain_all_frames.

22827 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
22829 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22831 * nsmenu.m (runDialogAt): Remove argument to timer_check.
22833 2011-03-27 Glenn Morris <rgm@gnu.org>
22835 * syssignal.h: Replace RETSIGTYPE with void.
22836 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
22837 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
22838 Replace SIGTYPE with void everywhere.
22839 * s/usg5-4-common.h (SIGTYPE): Remove definition.
22840 * s/template.h (SIGTYPE): Remove commented out definition.
22842 2011-03-26 Eli Zaretskii <eliz@gnu.org>
22844 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
22845 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
22847 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
22849 * w32.c (read_unc_volume): Use parameter `henum', instead of
22850 global variable `wget_enum_handle'.
22852 * keymap.c (describe_vector): Remove parameters `indices' and
22853 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
22854 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
22856 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
22858 * keyboard.c (timer_check): Remove parameter `do_it_now',
22859 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
22860 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
22861 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
22863 * keyboard.c (read_char):
22864 * w32menu.c (w32_menu_display_help):
22865 * xmenu.c (show_help_event, menu_help_callback):
22866 Adjust calls to `show_help_echo'.
22868 * gtkutil.c (xg_maybe_add_timer):
22869 * keyboard.c (readable_events):
22870 * process.c (wait_reading_process_output):
22871 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
22873 * insdel.c (adjust_markers_gap_motion):
22874 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
22875 (gap_left, gap_right): Don't call it.
22877 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
22879 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
22880 incurred during fontification.

22921 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
22923 * w32term.c (x_set_glyph_string_clipping):
22924 Don't pass uninitialized region to CombineRgn.
22926 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
22928 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
22929 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
22930 (Fx_close_connection): Remove unused variable `i'.
22932 * w32font.c (w32font_draw): Return number of glyphs.

22946 (uniscribe_font_driver): Add missing initializers.
22948 2011-03-23 Julien Danjou <julien@danjou.info>
22950 * term.c (Fsuspend_tty, Fresume_tty):
22951 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22952 * window.c (temp_output_buffer_show):
22953 * insdel.c (signal_before_change):
22954 * frame.c (Fhandle_switch_frame):
22955 * fileio.c (Fdo_auto_save):
22956 * emacs.c (Fkill_emacs):
22957 * editfns.c (save_excursion_restore):
22958 * cmds.c (internal_self_insert):
22959 * callint.c (Fcall_interactively):
22960 * buffer.c (Fkill_all_local_variables):
22961 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22963 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22964 unconditionally since it does the check itself.
22966 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22968 Fix more problems found by GCC 4.5.2's static checks.
22970 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22971 the first time through the loop, since we know p0 < p1 then.
22972 This also avoids a gcc -Wstrict-overflow warning.
22974 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22975 leading to a memory leak, possible in functions like
22976 load_charset_map_from_file that can allocate an unbounded number
22977 of objects (Bug#8318).
22979 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22980 that could (at least in theory) be that large.
22982 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22983 This is less likely to overflow, and avoids undefined behavior if
22984 overflow does occur. All callers changed. Use strtoul to scan
22985 for the unsigned long integer.
22986 (pint2hrstr): Simplify and tune code slightly.
22987 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22989 * scroll.c (do_scrolling): Work around GCC bug 48228.
22990 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22992 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22993 This also avoids a warning with gcc -Wstrict-overflow.
22994 (validate_x_resource_name): Simplify count usage.
22995 This also avoids a warning with gcc -Wstrict-overflow.
22997 * fileio.c (Fcopy_file): Report error if fchown or fchmod
23000 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
23002 * process.c (Fmake_network_process): Use socklen_t, not int,
23003 where POSIX says socklen_t is required in portable programs.
23004 This fixes a porting bug on hosts like 64-bit HP-UX, where
23005 socklen_t is wider than int (Bug#8277).
23006 (Fmake_network_process, server_accept_connection):
23007 (wait_reading_process_output, read_process_output):
23010 * process.c: Rename or move locals to avoid shadowing.
23011 (list_processes_1, Fmake_network_process):
23012 (read_process_output_error_handler, exec_sentinel_error_handler):
23013 Rename or move locals.
23014 (Fmake_network_process): Define label "retry_connect" only if needed.
23015 (Fnetwork_interface_info): Fix pointer signedness.
23016 (process_send_signal): Add cast to avoid pointer signedness problem.
23017 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
23018 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
23020 Make tparam.h and terminfo.c consistent.
23021 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
23022 Include tparam.h instead, since it declares them.
23023 * cm.h (PC): Remove extern decl; tparam.h now does this.
23024 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
23025 * terminfo.c: Include tparam.h, to check interfaces.
23026 (tparm): Make 1st arg a const pointer in decl. Put it at top level.

23082 clobbering (Bug#8298).
23083 * sysdep.c (sys_subshell): Likewise.
23084 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23086 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23087 This should get cleaned up, so that child_setup has the
23088 same signature on all platforms.
23090 * callproc.c (call_process_cleanup): Now static.
23091 (relocate_fd): Rename locals to avoid shadowing.
23093 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

23222 some of which prompt warnings from gcc -Wbad-function-cast.

23252 (Fmemory_limit): Cast sbrk's returned value to char *.
23254 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

23260 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23261 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23262 to use the following functions instead of these macros.
23263 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23264 EMACS_INT, since callers assume the returned value fits in int.
23265 (upcase1): Likewise, for UPCASE_TABLE.
23266 (uppercasep, lowercasep, upcase): New static inline functions.
23267 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

23277 (regex_compile, re_match_2_internal): Mark locals as initialized.
23278 (RETALLOC_IF): Define only if needed.
23279 (WORDCHAR_P): Likewise. This one is never needed, but is used
23280 only in a comment talking about a compiler bug, so put inside
23281 the #if 0 of that comment.
23282 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23283 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

23310 New macros, so that the caller can use some names other than
23311 gcpro1, gcpro2, etc.
23312 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23314 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23315 argument, for consistency with GCPRO2_VAR, etc: it is now the
23316 prefix of the variable, not the variable itself. All uses
23318 * dired.c (directory_files_internal, file_name_completion):
23319 Rename locals to avoid shadowing.
23321 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23322 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23323 dired.c's scmp function, had undefined behavior.
23324 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23325 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23326 * buffer.h: ... to here, because these macros use current_buffer,
23327 and the new implementation with inline functions needs to have
23328 current_buffer in scope now, rather than later when the macros
23330 (downcase, upcase1): New static inline functions.
23331 (DOWNCASE, UPCASE1): Reimplement using these functions.
23332 This avoids undefined behavior in expressions like
23333 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23334 from race conditions in accessing the global variables
23335 case_temp1 and case_temp2.
23336 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23337 * lisp.h (case_temp1, case_temp2): Remove their decls.
23338 * character.h (ASCII_CHAR_P): Move from here ...
23339 * lisp.h: ... to here, so that the inline functions mentioned
23340 above can use them.
23342 * dired.c (directory_files_internal_unwind): Now static.
23344 * fileio.c (file_name_as_directory, directory_file_name):

23347 (file_name_as_directory): Use const pointers when appropriate.
23348 (Fexpand_file_name): Likewise. In particular, newdir might
23349 point at constant storage, so make it a const pointer.
23350 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23351 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23353 (Fset_file_times, Finsert_file_contents, auto_save_error):

23358 to avoid shadowing.
23360 * marker.c (bytepos_to_charpos): Remove; unused.
23362 * lisp.h (verify_bytepos, count_markers): New decls,
23363 so that gcc does not warn that these functions aren't declared.
23365 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23366 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23367 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23368 (copy_text): Remove unused local var.
23370 * filelock.c (within_one_second): Now static.
23371 (lock_file_1): Rename local to avoid shadowing.
23373 * buffer.c (fix_overlays_before): Mark locals as initialized.
23374 (fix_start_end_in_overlays): Likewise. This function should be
23375 simplified by using pointers-to-pointers, but that's a different
23377 (switch_to_buffer_1): Now static.
23378 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23379 (report_overlay_modification): Rename locals to avoid shadowing.

23382 Fix pointer signedness issue.
23383 (sys_subshell): Mark local as volatile if checking for lint,
23384 to suppress a gcc -Wclobbered warning that does not seem to be right.
23385 (MAXPATHLEN): Define only if needed.
23387 * process.c (serial_open, serial_configure): Move decls from here ...
23388 * systty.h: ... to here, so that they can be checked.
23390 * fns.c (get_random, seed_random): Move extern decls from here ...
23391 * lisp.h: ... to here, so that they can be checked.
23393 * sysdep.c (reset_io): Now static.
23394 (wait_for_termination_signal): Remove; unused.
23396 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

23399 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
23400 (DENSE_TABLE_SIZE): Remove; unused.
23401 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23402 (describe_map_tree):
23403 Rename locals to avoid shadowing.
23405 * keyboard.c: Declare functions static if they are not used elsewhere.
