3 * xdisp.c (pos_visible_p): Use the special code for finding the
4 beginning of a display property or overlay for any "replacing"
5 display property, not just for display strings. This solves
6 incorrect reporting of position by posn-at-point. (Bug#14241)
8 2013-05-06 Paul Eggert <eggert@cs.ucla.edu>
10 * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
11 Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
12 Verify that ElfW (Half) fits in int.
13 (fatal): Use same signature as lisp.h.
14 (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
15 configure and build with -DUNEXELF_DEBUG without worrying about
16 other modules that use DEBUG.
17 (DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
18 possibly-wide integers now uses it instead of plain fprintf.
19 (entry_address): New function, which avoids problems with 32-bit
20 overflow on 64-bit hosts.
21 (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
22 (round_up): Don't assume the remainder fits in int.
23 (find_section): Use bool for boolean. Simplify debug code.
24 (unexec): Don't assume file sizes fit in int or size_t.
25 Omit unnecessary trailing newline in 'fatal' format.
26 Use strerror rather than outputting decimal error number.
27 Remove unused code when emacs is not defined;
28 this file relies on Emacs now.
29 Don't assume e_phnum and e_shnum are positive.
31 * regex.c: Fix problems when DEBUG is defined.
32 (extract_number, extract_number_and_incr): Define regardless of
33 whether DEBUG is defined; that's simpler and makes the code less
34 likely to go stale in the normal case when DEBUG is not defined.
35 Return int rather than taking an int * arg. All callers changed.
36 (DEBUG_PRINT1, DEBUG_PRINT2, DEBUG_PRINT3, DEBUG_PRINT4):
37 Remove, replacing with ...
38 (DEBUG_PRINT): New macro. All callers changed.
39 (DEBUG_COMPILES_ARGUMENTS): New macro.
40 (print_fastmap, print_partial_compiled_pattern) [DEBUG]:
41 (print_compiled_pattern, print_double_string) [DEBUG]:
42 Use prototype rather than old-style definition.
43 (print_partial_compiled_pattern, print_compiled_pattern) [DEBUG]:
44 (ENSURE_FAIL_STACK, PUSH_FAILURE_REG) [DEBUG]:
45 (POP_FAILURE_REG_OR_COUNT, PUSH_FAILURE_POINT) [DEBUG]:
46 (POP_FAILURE_POINT, re_match_2_internal) [DEBUG]:
47 Don't assume ptrdiff_t, size_t, and long are the same width as int.
48 (POINTER_TO_OFFSET): Return ptrdiff_t, not regoff_t.
49 This matters only when DEBUG is defined.
51 2013-05-05 Eli Zaretskii <eliz@gnu.org>
53 * xdisp.c (set_iterator_to_next): Set the
54 ignore_overlay_strings_at_pos_p flag only if we are _really_
55 iterating over an overlay string, as indicated by the
56 current.overlay_string_index member. (Bug#14306)
58 2013-05-05 Jan Djärv <jan.h.d@swipnet.se>
60 * nsmenu.m (ns_update_menubar): Move initialization of submenuTitle
61 to where it is used, to avoid autorelease issues (Bug#14050).
63 2013-05-05 Paul Eggert <eggert@cs.ucla.edu>
65 `write-region-inhibit-fsync' defaults to noninteractive (Bug#14273).
66 * fileio.c (syms_of_fileio): Implement this.
67 * filelock.c (create_lock_file): If symbolic links don't work, so
68 we use a regular file as a lock file, do not fsync the lock file;
71 2013-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
73 * minibuf.c (Fread_minibuffer, Feval_minibuffer): Move to Elisp.

76 * callint.c (Fcall_interactively): Adjust calls accordingly.
78 2013-05-04 Eli Zaretskii <eliz@gnu.org>
80 * dispextern.h (WINDOW_WANTS_HEADER_LINE_P): Verify that
81 w->contents is a buffer before computing everything else.
82 Use parentheses to disambiguate last part of the condition.
84 * w32fns.c (w32_wnd_proc): Remove temporary code used to trap
85 assertion violations. (Bug#14062)
87 2013-05-01 David Reitter <david.reitter@gmail.com>
89 * nsfns.m (ns_tooltip): Initialize.
91 2013-04-28 Eli Zaretskii <eliz@gnu.org>
93 * coding.c (decode_coding_gap): Don't remove the character before
94 a newline unless it's a CR character. (Bug#14287)
96 2013-04-28 Dan Nicolaescu <dann@gnu.org>
98 * dispextern.h (struct face): Move enum face_underline_type
99 earlier so that bitfields can be in the same word.
101 2013-04-28 Jan Djärv <jan.h.d@swipnet.se>
103 * nsfns.m (handlePanelKeys): New function.
104 (EmacsOpenPanel:performKeyEquivalent:)
105 (EmacsSavePanel:performKeyEquivalent:): Call handlePanelKeys to handle
106 arrows/function/control and copy/paste keys (Bug#14296).
108 2013-04-27 Juri Linkov <juri@jurta.org>
110 * callint.c (Fcall_interactively): Call `Qread_number' for
111 interactive code letter `n' instead of using duplicate code.
114 2013-04-27 Paul Eggert <eggert@cs.ucla.edu>
116 * systime.h (make_timeval): Declare as 'const'.
118 2013-04-27 Kenichi Handa <handa@gnu.org>
120 * font.c (font_open_entity): Always open a font of manageable
123 2013-04-26 Paul Eggert <eggert@cs.ucla.edu>
125 Port better to AIX (Bug#14258).
126 * lisp.h (ENUM_BF) [__IBMC__]: Make it 'unsigned int' here, too,
129 2013-04-24 Kenichi Handa <handa@gnu.org>
131 * coding.c (decode_coding_iso_2022): When an invalid escape
132 sequence is encountered, reset the invocation and designation
133 status to the safest one.
135 2013-04-22 Paul Eggert <eggert@cs.ucla.edu>
137 * Makefile.in (bootstrap-clean): Remove stamp-h1 too.
138 Without this fix, "make distclean" leaves stamp-h1 behind.
140 2013-04-20 Erik Charlebois <erikcharlebois@gmail.com>
142 * w32fns.c (w32_fullscreen_rect): New function to compute the
143 window rectangle for the given fullscreen mode.
144 (w32_wnd_proc): When in a fullscreen mode, WM_WINDOWPOSCHANGING no
145 longer tunes the window size. This keeps the window's edges flush
146 with the screen and allows the taskbar to hide itself in fullboth.
148 * w32term.c (w32fullscreen_hook): 'fullboth' now shows without
149 window decorations and uses the entire screen.
151 * w32term.h (w32_fullscreen_rect) Add prototype.
152 (struct w32_output): Replace normal_width, normal_height,
153 normal_top, and normal_left members with a single normal_placement
155 (FRAME_NORMAL_WIDTH, FRAME_NORMAL_HEIGHT, FRAME_NORMAL_TOP):
157 (FRAME_NORMAL_PLACEMENT): New macro.
159 2013-04-16 Juanma Barranquero <lekktu@gmail.com>
161 * minibuf.c (Ftest_completion): Silence compiler warning.
163 2013-04-15 Eli Zaretskii <eliz@gnu.org>
165 * w32fns.c (w32_wnd_proc): Add more assertions to investigate
168 * frame.h (WINDOW_FRAME): Protect macro and its argument with
171 * dispextern.h (CURRENT_MODE_LINE_HEIGHT)
172 (CURRENT_HEADER_LINE_HEIGHT, WINDOW_WANTS_MODELINE_P)
173 (WINDOW_WANTS_HEADER_LINE_P): Protect macro arguments with
174 parentheses where appropriate.
176 2013-04-14 Paul Eggert <eggert@cs.ucla.edu>
178 * keyboard.c (timer_start_idle): Remove no-longer-used local.
180 2013-04-14 Eli Zaretskii <eliz@gnu.org>
182 * buffer.c (syms_of_buffer) <left-margin-width, right-margin-width>
183 <left-fringe-width, right-fringe-width, fringes-outside-margins>:
184 Mention in the doc string that setting these variables takes
185 effect only after a call to set-window-buffer. (Bug#14200)
187 2013-04-13 Eli Zaretskii <eliz@gnu.org>
189 * indent.c (Fvertical_motion): Don't consider display strings on
190 overlay strings as display strings on the buffer position we
191 started from. This prevents vertical cursor motion from jumping
192 more than one line when there's an overlay string with a display
193 property at end of line.
194 Reported by Karl Chen <Karl.Chen@quarl.org> in
195 http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00362.html.
197 2013-04-12 Stefan Monnier <monnier@iro.umontreal.ca>
199 * window.c (select_window): `record_buffer' even if window is
200 already selected (bug#14191).
202 2013-04-11 Eli Zaretskii <eliz@gnu.org>
204 * window.c (Fwindow_end): Test more flags, including the buffer's
205 last_overlay_modified flag, to determine whether the window's
206 display is really up-to-date. Prevents the function from
207 returning a stale value. (Bug#14170)
208 (Fwindow_line_height): Fix the test for up-to-date-ness of the
211 2013-04-10 Eli Zaretskii <eliz@gnu.org>
213 * frame.c (do_switch_frame): Mark the TTY frame we switch to as
214 garbaged only if it is not already the top frame on its TTY.
215 This prevents flickering due to constant redrawing of TTY frames when
216 there are GUI frames open in the same session. (Bug#13864)
218 2013-04-10 Stefan Monnier <monnier@iro.umontreal.ca>
220 * keyboard.c (timer_start_idle): Call internal-timer-start-idle instead
221 of marking the idle timers directly.
223 2013-04-09 Stefan Monnier <monnier@iro.umontreal.ca>
225 * minibuf.c (Ftest_completion): Ignore non-string/symbol keys in hash
228 2013-04-08 Stefan Monnier <monnier@iro.umontreal.ca>

245 2013-03-31 Jan Djärv <jan.h.d@swipnet.se>
247 * nsterm.m (ns_mouse_position): Use NS_FRAME_P instead of checking
250 2013-04-07 Paul Eggert <eggert@cs.ucla.edu>
252 Fix --enable-profiling bug introduced by 2013-02-25 change (Bug#13783).
253 This bug was introduced by my 2013-02-25 change that simplified
254 data_start configuration. Without this change, on GNU/Linux
255 an Emacs configured with --enable-profiling fails immediately
256 due to a profiler signal.
257 * Makefile.in: Compile with $(PROFILING_CFLAGS), but do not link
258 with these flags. On platforms where special flags are needed
259 when linking temacs, the flags are now in LD_SWITCH_SYSTEM_TEMACS.
260 (ALL_CFLAGS): Remove $(PROFILING_CFLAGS).
261 (.c.o, .m.o): Compile with $(PROFILING_CFLAGS).
263 2013-04-07 Dmitry Antipov <dmantipov@yandex.ru>
265 Get rid of some platform-specific functions examining window
266 system and its capabilities. This is a partial rework of the
268 * lisp.h (have_menus_p): Remove prototype. This function is
269 replaced with platform-independent window_system_available.
270 (check_window_system): Move to...
271 * frame.h (decode_window_system_frame, window_system_available):
272 ...here, add new prototypes.

281 * msdos.c (have_menus_p): Remove.
282 * nsfns.m (check_window_system, have_menus_p, check_ns_frame):
283 Remove platform-specific functions. Use check_window_system,
284 decode_window_system_frame and check_ns_display_info where

300 changed. Check EOL format. Do not call adjust_coding_eol_type
302 (check_utf_8): New function.
303 (adjust_coding_eol_type): Do nothing if already adjusted.
304 (detect_coding): Compare the return value of check_ascii with
305 coding->src_bytes. Call adjust_coding_eol_type if necessary.
306 (decode_coding_gap): Optimize for valid UTF-8.
308 2013-03-21 Kenichi Handa <handa@gnu.org>
310 * coding.c (syms_of_coding): Cancel previous change.
312 * insdel.c (insert_from_gap): Fix previous change.
314 2013-04-05 Dmitry Antipov <dmantipov@yandex.ru>

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

365 * dispnew.c (sit_for): Don't mishandle NaNs.
366 This fixes a bug introduced in the 2013-03-24 change.
367 * editfns.c (decode_time_components): Don't hoist comparison.
368 This fixes another bug introduced in the 2013-03-24 change.

422 2013-03-28 Dmitry Antipov <dmantipov@yandex.ru>
424 * window.h (struct window): Replace hchild, vchild and buffer slots
425 with the only contents slot. This is possible because each valid
426 window may have either the child window (in vertical or horizontal
427 combination) or buffer to display (for the leaf window). Using that,
428 a lof of operations to traverse and/or change window hierarchies may
429 be simplified. New member horizontal is used to distinguish between

466 (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree)
467 (expose_window_tree): Likewise.
468 Use contents slot, not buffer, where appropriate.
469 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
470 to avoid deleted windows. Use contents slot instead of buffer.
471 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
472 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:
473 * nsfns.m, nsmenu.m, nsterm.m, print.c, w32fns.c, w32menu.c, xfaces.c:
474 * xfns.c, xmenu.c: Use contents slot, not buffer, where appropriate.

655 'fullscreen' parameter. Always record previous width and height
656 of the frame, except when switching out of maximized modes, so
657 that they could be restored correctly, instead of resetting to the
658 default frame dimensions. Send SC_RESTORE command to the frame,
659 unless we are going to send SC_MAXIMIZE, to restore the frame
660 resize hints in the mouse pointer shown by the window manager.

694 * alloc.c: Verify some properties of Lisp_Save_Value's representation.
695 (make_save_value): Change 1st arg from string to enum. All callers
698 (mark_object): Use if, not #if, for GC_MARK_STACK.

721 (WINDOW_TOTAL_COLS, WINDOW_TOTAL_LINES, WINDOW_LEFT_EDGE_COL)
722 (WINDOW_TOP_EDGE_LINE): Drop Lisp_Object to integer conversion.
723 * dispnew.c, frame.c, w32fns.c, window.c, xdisp.c, xfns.c:
724 Adjust users where appropriate.
726 2013-03-20 Dmitry Antipov <dmantipov@yandex.ru>

806 * coding.h (struct coding_system): New member eol_seen.
808 * coding.c (detect_ascii): New function.
809 (detect_coding): Set coding->head_ascii and coding->eol_seen only
810 when the source bytes are actually scanned. On detecting for
811 coding_category_utf_8_auto, call detect_ascii instead of scanning
812 source bytes directly.
813 (produce_chars): Call insert_from_gap with the new arg 0.
814 (encode_coding): Likewise.
815 (decode_coding_gap): Control ASCII optimization by the variable

848 * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
849 too so that these builds can use Cygwin's file conversion
850 functions. (We've been building and linking cygw32.o all along
851 and just not using it.)
853 2013-03-13 Paul Eggert <eggert@cs.ucla.edu>

866 * w32term.c (w32_read_socket): If the Emacs frame is being
867 activated, call w32fullscreen_hook, to make sure the new frame
868 dimensions are in effect. (Bug#13937)
870 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
872 * xdisp.c (init_iterator): Simplify because both character and byte
873 positions are either specified or -1. Add eassert. Adjust comment.
874 * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
875 character and byte positions can be obtained from marker.

895 Include <sys/param.h> unconditionally, as that works elsewhere and
896 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
897 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

904 2013-03-11 Stefan Monnier <monnier@iro.umontreal.ca>

932 can just use du like other systems.
934 * coding.c (from_unicode_buffer): Declare.
935 * coding.c (from_unicode_buffer): Implement.
937 2013-03-10 Stefan Monnier <monnier@iro.umontreal.ca>

983 * keyboard.h (EVENT_START, EVENT_END, POSN_WINDOW, POSN_POSN)
984 (POSN_WINDOW_POSN, POSN_TIMESTAMP): Be careful since events may come
985 from Elisp via unread-command-events.
987 * keyboard.c (access_keymap_keyremap): Accept nil return value from
988 functions to mean "no change".
990 2013-03-08 Paul Eggert <eggert@cs.ucla.edu>

999 Use bool for boolean.
1000 * region-cache.c (region_cache_forward, region_cache_backward):
1001 Fix comments to match code: these functions return int, not boolean.
1003 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1005 * search.c (find_newline): Accept start and end byte positions
1006 as arguments and allow -1 if not known.

1038 2013-03-08 Dmitry Antipov <dmantipov@yandex.ru>
1040 * bidi.c (bidi_fetch_char): Swap first and second arguments
1041 to match other functions accepting character and byte positions.
1043 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

1045 when you need just to move to the previous buffer position.
1046 * xdisp.c (Fcurrent_bidi_paragraph_direction): Use DEC_BOTH.
1048 2013-03-07 Eli Zaretskii <eliz@gnu.org>

1123 Fix a build failure on OpenBSD 4.x and MirBSD (Bug#13881).
1124 * sysdep.c (list_system_processes)
1125 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
1126 Make it a stub in this case; otherwise the build might fail,
1127 and this code hasn't been tested on such hosts anyway.
1128 Problem reported by Nelson H. F. Beebe in
1129 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
1130 and analyzed by Jérémie Courrèges-Anglas in

1133 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
1135 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.
1136 * xdisp.c (back_to_previous_line_start, forward_to_next_line_start)
1137 (get_visually_first_element, move_it_vertically_backward): Ajust users.

1141 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
1143 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
1144 * filelock.c: Include <c-ctype.h>.
1145 (MAX_LFINFO): New top-level constant.
1146 (lock_info_type): Remove members pid, boot_time. Add members at,
1147 dot, colon. Change user member to be the entire buffer, not a
1148 pointer. This allows us to handle the case where a foreign
1149 pid or boot time exceeds the local range. All uses changed.
1150 (LINKS_MIGHT_NOT_WORK): New constant.
1151 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
1152 (defined_WINDOWSNT): Remove.
1153 (MAKE_LOCK_NAME, file_in_lock_file_name):
1154 Always use .#FILE (not .#-FILE) for the file lock,
1155 even if it is a regular file.
1156 (rename_lock_file): New function.
1157 (create_lock_file): Use it.
1158 (create_lock_file, read_lock_data):
1159 Prefer a symbolic link for the lock file, falling back on a
1160 regular file if symlinks don't work. Do not try to create
1161 symlinks on MS-Windows, due to security hassles. Stick with
1162 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
1163 link, rename, unlink, mkstemp) when creating locks, as a GNUish
1164 host may be using a Windowsish file system, and cannot use
1165 MS-Windows-only system calls. Fall back on mktemp if mkstemp
1166 doesn't work. Don't fail merely because of a symlink-contents
1167 length limit in the current file system; fall back on regular
1168 files. Increase the symlink contents length limit to 8 KiB, this
1169 should be big enough for any real use and doesn't crunch the
1171 (create_lock_file, lock_file_1, read_lock_data):
1172 Simplify allocation of lock file buffers now that they fit in 8 KiB.
1173 (lock_file_1): Return error number, not bool. All callers changed.
1174 (ELOOP): New macro, if not already defined.
1175 (read_lock_data): Return size of lock file contents, not Lisp object.
1176 All callers changed. Handle a race condition if some other process
1177 replaces a regular-file lock with a symlink lock or vice versa,
1178 while we're trying to read the lock.
1179 (current_lock_owner): Parse contents more carefully, to help avoid
1180 confusing a regular-file lock with some other application's use
1181 of the file. Check for lock file contents being too long, or
1182 not parsing correctly.
1183 (current_lock_owner, lock_file):
1184 Allow foreign pid and boot times that exceed the local range.
1185 (current_lock_owner, lock_if_free, lock_file):
1186 Simplify allocation of lock file contents.
1187 * w32.c (sys_rename_replace): New function, containing most of
1188 the contents of the old sys_rename.
1189 (sys_rename): Use it.
1190 (fchmod): New dummy function.
1191 * w32.h (sys_rename_replace, fchmod): New decls.
1193 2013-03-05 Eli Zaretskii <eliz@gnu.org>
1195 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
1196 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
1197 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
1198 <dmantipov@yandex.ru>.
1200 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
1202 * composite.c (get_composition_id, fill_gstring_header):
1203 Use make_uninit_vector where appropriate.
1204 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
1205 * xselect.c (clean_local_selection_data): Likewise.
1207 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
1209 Fix misuse of ImageMagick that caused core dump (Bug#13846).
1210 * image.c (imagemagick_load_image): Calculate height and width
1211 after flattening the image, not before.
1213 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
1215 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
1216 * ftfont.c (ftfont_shape_by_flt): Likewise.
1217 * w32uniscribe.c (uniscribe_shape): Likewise.
1219 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1221 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
1222 The old approach, which fell back on DIR/.#FILE.0 through
1223 DIR/.#FILE.9, had race conditions that could not be easily fixed.
1224 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
1225 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
1226 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
1227 because the locking mechanism was never reliable in that case).
1228 This patch fixes this and other bugs discovered by a code
1229 inspection that was prompted by
1230 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
1231 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
1232 to avoid interoperability problems between the MS-Windows and
1233 non-MS-Windows implementations. MS-Windows and non-MS-Windows
1234 instances of Emacs now ignore each others' locks.
1235 * filelock.c (defined_WINDOWSNT): New constant.
1236 (MAKE_LOCK_NAME, fill_in_lock_file_name):
1237 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
1238 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
1239 regular files on MS-Windows hosts.
1240 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
1241 Use SAFE_ALLOCA to avoid problems with long file names.
1242 (MAX_LFINFO): Now a local constant, not a global macro.
1243 (IS_LOCK_FILE): Remove.
1244 (lock_file_1): Don't inspect errno if symlink call succeeds;
1245 that's not portable.
1246 (lock_file): Document that this function can return if lock
1248 (lock_file): Don't access freed storage.
1250 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>
1252 * lisp.h (XPNTR) [!USE_LSB_TAG]: Remove extra paren. (Bug#13734)
1254 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
1256 * textprop.c: Use bool for booleans.
1257 (validate_interval_range, Fadd_text_properties)
1258 (Fremove_text_properties): Prefer bool to int when either works.
1260 2013-03-02 Eli Zaretskii <eliz@gnu.org>
1262 * textprop.c (Fadd_text_properties, Fremove_text_properties):
1263 If the interval tree changes as a side effect of calling
1264 modify_region, re-do processing starting from the call to
1265 validate_interval_range. (Bug#13743)
1267 2013-02-28 Eli Zaretskii <eliz@gnu.org>
1269 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
1272 2013-02-27 Eli Zaretskii <eliz@gnu.org>
1274 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
1275 _SH_DENYRW flag, instead of emacs_open, to deny any other process
1276 access to the lock file until it is written and closed.
1279 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
1281 * callint.c (Qcall_interactively):
1282 * macros.c (Qexecute_kbd_macro):

1287 * window.c (Frecenter): Tiny docstring enhancement.
1289 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
1291 Minor textprop integer cleanup.
1292 * intervals.h, textprop.c (add_text_properties_from_list):
1293 Return void, not int, since nobody uses the return value.
1294 * textprop.c (validate_plist, add_properties, remove_properties)
1295 (Fadd_text_properties):
1296 Don't assume list length fits in int.
1297 (interval_has_all_properties, interval_has_some_properties)
1298 (interval_has_some_properties_list, add_properties, remove_properties)

1300 (Fremove_list_of_text_properties, text_property_stickiness):
1301 Use bool for booleans.
1302 (Fadd_text_properties, Fremove_text_properties):
1303 (Fremove_list_of_text_properties):
1304 Reindent do-while as per GNU style.
1306 2013-02-25 Eli Zaretskii <eliz@gnu.org>
1308 Implement CLASH_DETECTION for MS-Windows.
1310 * filelock.c [WINDOWSNT]: Include w32.h.
1311 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
1312 function of that name. Up-case the macro arguments.
1313 (IS_LOCK_FILE): New macro.
1314 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
1315 (create_lock_file): New function, with body extracted from
1317 [WINDOWSNT]: Implement lock files by writing a regular file with
1318 the lock information as its contents.
1319 (read_lock_data): New function, on Posix platforms just calls
1321 [WINDOWSNT]: Read the lock info from the file.
1322 (current_lock_owner): Call read_lock_data instead of calling
1323 emacs_readlinkat directly.
1324 (lock_file) [WINDOWSNT]: Run the file name through
1327 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
1328 just check if the process by that PID exists.
1330 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
1331 also present, as doing so will fail to error out if the file
1334 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
1336 * textprop.c (Fadd_text_properties, Fremove_text_properties)
1337 (Fremove_list_of_text_properties): Skip all of the intervals in
1338 the region between START and END that already have resp. don't
1339 have the requested properties, not just the first one.
1340 Add assertions that the loop afterwards always modifies the
1341 properties. (Bug#13743)

1371 * vm-limit.c: Move most of mem-limits.h's contents here.
1372 (data_start): New decl. It's OK if this is approximate,
1373 so simplify-away some unnecessary exactness.
1374 (POINTER): Remove; all uses removed.
1375 (data_space_start): Now char *, to avoid casts.
1376 (exceeds_lisp_ptr): New function, replacing the old

1401 Remove, replacing all uses with C89 equivalents. These old
1402 symbols were present only for porting to pre-C89 platforms.
1404 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1406 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.

1422 2013-02-19 Daniel Colascione <dancol@dancol.org>
1424 * sheap.c (report_sheap_usage): Use message, not message1, so
1425 that we don't try to create a buffer while we're in the middle
1426 of dumping Emacs. Explain why.
1428 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1430 * search.c (find_newline): Return byte position in bytepos.

1440 (get_visually_first_element, move_it_vertically_backward):
1441 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
1443 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1445 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1446 resources were not orderly released.
1448 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1450 * xdisp.c (x_draw_vertical_border): For a window that is neither
1451 the leftmost nor the rightmost, redraw both the left and the right
1452 vertical borders. (Bug#13723)

1463 * editfns.c (Fmessage, Fmessage_box):
1464 * callint.c (Fcall_interactively):
1465 * fns.c (Fyes_or_no_p): Prefer `message1' over `message'.
1467 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
1469 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
1470 * frame.c (syms_of_frame): ... to here.
1472 2013-02-16 Eli Zaretskii <eliz@gnu.org>
1474 * w32.c (sys_chown): Remove unused function.
1476 * w32term.c <input_signal_count>: Declare 'volatile'
1477 unconditionally. (Bug#9066)
1479 * w32.c (set_errno): Reset h_errno and don't set it to any other
1480 value. Set errno instead.
1481 (check_errno): Reset h_errno.
1482 (sys_socket, socket_to_fd, sys_bind, sys_connect)
1483 (sys_gethostname, sys_getservbyname, sys_getpeername)
1484 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1485 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
1487 (sys_gethostbyname): Set h_errno only errors detected.
1489 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1491 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
1493 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1495 * keyboard.c (read_char): Fix calculation of auto-save time out
1496 when auto-save-timeout is less than 4. (Bug#13720)
1498 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1499 time. Improve diagnostics in DebPrint. (Bug#13546)
1501 * w32.c (sys_socket, sys_bind, sys_connect, sys_gethostname)
1502 (sys_gethostbyname, sys_getservbyname, sys_getpeername)

1507 value that is out of bounds.
1508 (sys_accept): If fd is negative, do not set up the child_process
1509 structure for reading.
1511 2013-02-15 Dmitry Antipov <dmantipov@yandex.ru>
1513 * composite.c (fill_gstring_header): Remove useless prototype.

1525 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1527 Fix AIX port (Bug#13650).
1528 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1529 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1530 was #undeffed earlier, so it cannot be used as a macro here.
1531 Use the constant and not the macro.
1533 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1535 * w32proc.c (new_child): If no vacant slots are found in
1536 child_procs[], make another pass looking for slots whose process
1537 has exited or died. (Bug#13546)
1539 * w32.c (sys_pipe): When failing due to file descriptors above
1540 MAXDESC, set errno to EMFILE.
1541 (_sys_read_ahead): Update cp->status when failing to read serial
1542 communications input, so that the status doesn't stay at
1543 STATUS_READ_IN_PROGRESS. (Bug#13546)
1545 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1547 * gtkutil.c (tb_size_cb): New function.
1548 (xg_create_tool_bar): Connect size-allocate to tb_size_cb (Bug#13512).
1550 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1552 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1555 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1557 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1559 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1565 Break long line. Remove useless prototype and format comment.
1567 2013-02-13 Glenn Morris <rgm@gnu.org>
1569 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1571 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1573 Improve AIX port some more (Bug#13650).
1574 With this, it should be as good as it was in 23.3, though it's
1575 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1576 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1577 * unexaix.c (start_of_text): Remove.
1578 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1579 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1580 (orig_load_scnptr, orig_data_scnptr):
1581 Now off_t, not long, since they are file offsets.
1582 (make_hdr): Use _data, not start_of_data ().
1583 This is the key part of the fix.
1584 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1585 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1587 * pre-crt0.c (data_start): Initialize to 1.
1588 This ports to compilers that optimize the external declaration
1589 'int x = 0;' as if it were 'int x;' to shrink the executable.
1591 Improve AIX port (Bug#13650).
1592 This doesn't fix the bug, but it makes progress: Emacs builds now.
1593 * unexaix.c: Include inttypes.h, stdarg.h.
1594 (report_error, report_error_1): Mark as _Noreturn.
1595 (report_error): Don't report the wrong errno.
1596 (report_error_1): Now varargs. All callers changed.
1597 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1598 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1599 (write_ptr): Use %p to print address rather than %lx and a cast
1600 to unsigned long. Grow buffer a bit, to be safer.
1602 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1604 * bidi.c (bidi_resolve_neutral): After finding the next
1605 non-neutral character, accept NEUTRAL_ON type as well, because
1606 directional control characters, such as LRE and RLE, have their
1607 type converted to that by bidi_resolve_weak. This avoids aborts
1608 when LRE/RLE follows a run of neutrals.
1609 (bidi_move_to_visually_next): Assert that return value of
1610 bidi_peek_at_next_level is non-negative. Negative values will
1613 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1615 Minor getenv-related fixes.
1616 * callproc.c (Fcall_process_region) [!DOS_NT]:
1617 Avoid unnecessary duplicate call to getenv.
1618 * callproc.c (init_callproc):
1619 * dispnew.c (init_display):
1620 * sysdep.c (sys_subshell):
1621 Omit unnecessary cast of getenv or egetenv.
1623 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1625 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1626 Update dependencies.
1628 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1630 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1632 (display_line): Set w->region_showing to the value of
1633 it->region_beg_charpos, not to -1. This fixes redisplay
1634 optimization when cursor is moved up after M->. (Bug#13623)
1636 (try_scrolling): Scroll text up more if point is too close to ZV
1637 and inside the scroll margin. This makes sure point is moved
1638 outside the scroll margin in these cases.
1640 * window.h (struct window): region_showing can no longer be
1643 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1645 Tune by using memchr and memrchr.
1646 * doc.c (Fsnarf_documentation):
1647 * fileio.c (Fsubstitute_in_file_name):
1648 * search.c (find_newline, scan_newline):
1649 * xdisp.c (pos_visible_p, display_count_lines):
1650 Use memchr and memrchr rather than scanning byte-by-byte.
1651 * search.c (find_newline): Rename from scan_buffer.
1652 Omit first arg TARGET, as it's always '\n'. All callers changed.
1654 Clean up read_key_sequence a tiny bit more.
1655 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1656 (read_key_sequence): Remove unused locals.
1658 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1660 Clean up read_key_sequence a bit; reread active keymaps after first event.
1661 * keyboard.c (read_char, read_char_x_menu_prompt)
1662 (read_char_minibuf_menu_prompt):
1663 Replace nmaps+maps with a single `map' arg.
1664 (follow_key): Operate on a single map.
1665 (active_maps): New function.
1666 (test_undefined): Also return true for nil bindings.
1667 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1668 a single (composed) keymap. Remember `first_event' to choose the right
1669 set of active keymaps. Recompute the set of keymaps after receiving
1670 the first event. Remove GOBBLE_FIRST_EVENT.
1671 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1672 * keyboard.h (read_char): Update declaration.
1673 * lread.c (read_filtered_event): Adjust call to read_char.
1675 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1677 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1678 Don't use the limitation on backwards movement when lines are truncated
1679 in the window. (Bug#13675)
1681 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1683 * marker.c (set_marker_internal): If desired position is passed
1684 as a marker, avoid call to buf_charpos_to_bytepos.
1685 * window.c (Fset_window_point): Omit redundant type checking.
1686 (Fset_window_start): Likewise. Format comment.
1687 (window_scroll_pixel_based): Use set_marker_restricted_both
1688 with character and byte positions obtained from an iterator.
1689 (Fset_window_configuration): Use set_marker_restricted_both.
1690 * xdisp.c (message_dolog): Likewise.
1692 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1694 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1695 When text lines are longer than window's screen lines, don't move back
1696 too far. This speeds up some redisplay operations. (Bug#13675)
1698 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1700 * syntax.c (scan_sexps_forward): Fix byte position calculation
1701 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1703 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>
1705 * fileio.c (Fexpand_file_name): Omit confusing pointer comparison
1706 that was not needed.
1708 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1710 Minor hashing refactoring.
1711 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1712 (sxhash_float): Return EMACS_UINT, for consistency with the other
1714 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1715 non-static inline function and therefore can't use static vars.
1716 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1717 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1718 with the other hash functions.
1720 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1722 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1723 XXXXXX part of the temporary file pattern is not downcased even
1724 when w32-downcase-file-names is non-nil. (Bug#13661)
1726 * xdisp.c (decode_mode_spec): Remove handling of %t.
1728 * msdos.c (careadlinkatcwd): Remove.
1730 2013-02-08 Stefan Monnier <monnier@iro.umontreal.ca>
1732 * lread.c (skip_dyn_bytes): New function (bug#12598).
1733 (read1): Use it. Use getc instead of READCHAR to read bytes.
1734 (load_each_byte): Remove. Update users.
1736 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1738 * search.c (scan_buffer): Calculate end byte position just once.

1742 (scan_sexps_forward): Record from_byte and avoid redundant
1743 character to byte position calculation ...
1744 (Fparse_partial_sexp): ... here. Break too long line.
1746 2013-02-08 Dmitry Antipov <dmantipov@yandex.ru>
1748 * lisp.h (make_uninit_vector): New function.
1749 * alloc.c (Fvector, Fmake_byte_code):

1761 * window.c (Fcurrent_window_configuration):
1762 * xfaces.c (Fx_family_fonts):
1763 * xselect.c (selection_data_to_lisp_data): Use it.
1765 2013-02-07 Dmitry Antipov <dmantipov@yandex.ru>
1767 * coding.c (Fdefine_coding_system_internal): Use AREF where
1768 argument is known to be a vector.
1769 * fns.c (Flocale_info): Likewise for ASET.
1770 * xselect.c (selection_data_to_lisp_data): Likewise for ASET.
1771 * w32fns.c (w32_parse_hot_key): Likewise for ASIZE and AREF.
1773 2013-02-05 Jan Djärv <jan.h.d@swipnet.se>
1775 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1778 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.
1779 (EmacsView): Add fs_is_native, fsIsNative, isFullscreen and
1780 updateCollectionBehaviour.

1783 (ns_last_use_native_fullscreen): New variable.
1784 (x_make_frame_visible): Replace NEW_STYLE_FS with isFullscreen.

1786 if isFullscreen returns YES.
1787 (ns_fullscreen_hook): Replace NEW_STYLE_FS with isFullscreen.
1788 (check_native_fs): New function.
1789 (ns_select, ns_read_socket): Call check_native_fs if HAVE_NATIVE_FS.
1790 (ns_term_init): Remove NEW_STYLE_FS.
1791 (updateFrameSize:, windowWillResize:toSize:): Only adjust for title bar
1792 and tool bar if isFullscreen returns NO.
1793 (windowDidResize:): Replace NEW_STYLE_FS with fsIsNative.
1794 (initFrameFromEmacs:): Initialize fs_is_native. Replace NEW_STYLE_FS
1795 with HAVE_NATIVE_FS.
1796 (window:willUseFullScreenPresentationOptions:): New method.
1797 (windowDidEnterFullScreen:): Replace NEW_STYLE_FS with fsIsNative.
1798 Hide toolbar if not enabled (Bug#13444).
1799 (windowDidExitFullScreen:): Call updateCollectionBehaviour.
1800 Restore tool bar if enabled, hide it otherwise (Bug#13444).
1801 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1802 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1803 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1804 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1805 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1806 (syms_of_nsterm): Add ns-use-native-fullscreen.
1808 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1810 * fileio.c (Qchoose_write_coding_system): Now static.
1812 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1814 * xdisp.c (window_buffer_changed): region_showing can be negative,
1815 which still means region is being displayed.
1816 (redisplay_internal): Resurrect code that forced redisplay of the
1817 whole window when showing region and the mark has changed.
1818 Record the new mark position to allow redisplay optimizations.
1819 (display_line): If it->region_beg_charpos is non-zero, set the
1820 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1822 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1823 not bitfield of 1 bit.
1825 2013-02-03 Daniel Colascione <dancol@dancol.org>
1827 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1828 daemon mode works on cygw32 when Emacs is installed and not just
1831 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1833 Avoid file time stamp bug on MS-Windows (Bug#13149).
1834 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1835 as FAT32 doesn't update time stamps when truncating them.
1836 Also, check that a file time stamp is not a multiple of 100 ns;
1837 this should catch all instances of the problem on MS-Windows,
1838 as its native file system resolution is 100 ns or worse, and
1839 checking for a non-multiple of 100 ns should impose only a small
1840 overhead on systems with ns resolution.
1842 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1844 Avoid encoding file names on MS-Windows when they need to be run
1845 through dostounix_filename.
1846 * w32.c (normalize_filename): Accept an additional argument
1847 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1848 downcase it even if w32-downcase-file-names is non-nil.
1849 (dostounix_filename): Accept an additional argument MULTIBYTE and
1850 pass it to normalize_filename.
1851 (emacs_root_dir): Adjust.
1853 * msdos.h (dostounix_filename): Adjust prototype.
1855 * w32.h (dostounix_filename): Adjust prototype.
1857 * msdos.c (dostounix_filename): Accept an additional argument and
1859 (init_environment): Adjust callers of dostounix_filename.
1861 * fileio.c (Ffile_name_directory, file_name_as_directory)
1862 (directory_file_name, Fexpand_file_name)
1863 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1865 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1867 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1868 variables, as egetenv is case-insensitive for DOS_NT.
1870 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1871 with an encoded file name.
1873 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1874 Adjust calls to dostounix_filename.
1876 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.

1882 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1885 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1888 * callproc.c (Fcall_process): Make sure program name in PATH and
1889 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1890 is passed to exec/spawnve, which fails unless the file-name
1893 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1894 even if w32-quote-process-args is nil.
1896 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1898 Fix timestamp bug when write-region appends nothing (Bug#13149).
1899 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1900 the file's time stamp doesn't change if Emacs happens to write nothing
1901 to the file, and on a buggy file system this could cause Emacs to
1902 incorrectly infer that the file system doesn't have the bug.
1903 Avoid this problem by inhibiting the inference in this case.
1905 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1907 * window.h (struct window): Convert base_line_number, base_line_pos

1910 Remove sequence_number member. Adjust comments.
1911 * window.c (sequence_number): Remove.
1912 (make_window): Initialize column_number_displayed.
1913 * print.c (print_object): Follow the printed representation of
1914 frames and print window pointer to distinguish between windows.
1915 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1916 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1917 (wset_column_number_displayed, wset_region_showing): Remove.
1918 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1919 (try_scrolling, try_cursor_movement, redisplay_window)
1920 (try_window_reusing_current_matrix, try_window_id, display_line)
1921 (display_mode_lines, decode_mode_spec): Adjust users.
1922 * .gdbinit (pwinx): Do not print sequence_number.
1924 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1926 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1927 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1928 * dired.c: Include <fcntl.h>.
1929 (open_directory): New function, which uses open and fdopendir
1930 rather than opendir. DOS_NT platforms still use opendir, though.
1931 (directory_files_internal, file_name_completion): Use it.
1932 (file_attributes): New function, with most of the old Ffile_attributes.
1933 (directory_files_internal, Ffile_attributes): Use it.
1934 (file_attributes, file_name_completion_stat): First arg is now fd,
1935 not dir name. All uses changed. Use fstatat rather than lstat +
1937 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1938 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1939 (emacs_readlinkat): New function, with much of the old
1940 Ffile_symlink_p, but with an fd argument for speed.
1941 It uses readlinkat rather than careadlinkatcwd, so that it
1942 need not assume the working directory.
1943 (Ffile_symlink_p): Use it.
1944 * filelock.c (current_lock_owner): Use emacs_readlinkat
1945 rather than emacs_readlink.
1946 * lisp.h (emacs_readlinkat): New decl.
1947 (READLINK_BUFSIZE, emacs_readlink): Remove.
1948 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1949 (emacs_norealloc_allocator, emacs_readlink): Remove.
1950 This stuff is moved to fileio.c.
1951 * w32.c (fstatat, readlinkat): New functions.
1952 (careadlinkat): Don't check that fd == AT_FDCWD.
1953 (careadlinkatcwd): Remove; no longer needed.

1958 (Fwrite_region): Update for new choose_write_coding_system args.
1959 Move the last piece of choose_write_coding_system here. (Bug#13522)
1960 (syms_of_fileio): Add choose-write-coding-system.
1962 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1964 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1965 (sys_close): Zero out the flags for the file descriptor before
1966 closing it. (Bug#13546)
1968 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1969 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1970 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1973 * w32.c (w32_get_long_filename, init_environment, readlink):
1974 Support file names encoded in DBCS codepages.
1975 (readlink): Use the current file-name-coding-system, not the ANSI
1976 codepage, to decode and handle targets of symlinks.
1978 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1980 * w32.c (opendir): Now accepts a 'const char *'.
1982 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1984 Remove obsolete redisplay code. See the discussion at
1985 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1986 * dispnew.c (preemption_period, preemption_next_check): Remove.
1987 (Vredisplay_preemption_period): Likewise.
1988 (update_frame, update_single_window, update_window, update_frame_1):
1989 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1990 used, following the 2012-06-22 change.
1992 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1994 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1996 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1998 * font.c (num_fonts): Remove the leftover from old
1999 debugging code. Adjust comment style here and there.
2000 * insdel.c (insert_1): Remove.
2001 * lisp.h (insert_1): Remove prototype.
2002 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
2004 2013-01-25 Eli Zaretskii <eliz@gnu.org>
2006 * w32.c (max_filename_mbslen): New function.
2007 (normalize_filename, readdir): Use it to detect locales where ANSI
2008 encoding of file names uses a double-byte character set (DBCS).
2009 If a DBCS encoding is used, advance by characters using
2010 CharNextExA, instead of incrementing a 'char *' pointer.
2011 Use _mbslwr instead of _strlwr. (Bug#13515)
2013 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
2014 request of memory reservation to 1.7GB. (Bug#13065)
2016 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
2018 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
2019 at check_extra_latin label. (Bug#13505)
2021 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2023 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
2024 Avoid redundant calls to strlen.
2026 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2028 Drop async_visible and async_iconified fields of struct frame.
2029 This is possible because async input is gone; for details, see
2030 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
2031 * frame.h (struct frame): Remove async_visible and async_iconified
2032 members, convert garbaged to unsigned bitfield. Adjust comments.
2033 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
2034 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
2035 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
2036 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
2037 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
2039 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
2040 properly. Likewise for obscured.
2042 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
2045 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
2047 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
2049 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
2050 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
2052 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
2054 * xdisp.c (message2, message2_nolog): Remove functions.
2055 (message3, message3_nolog): Extract nbytes and multibyteness directly
2056 from the string. Change all callers.
2057 (message3_nolog): Don't set message_enable_multibyte since set_message
2058 will reset it anyway.
2059 (message1, message1_nolog): Use message3.
2060 (vmessage): Use a stack allocated buffer rather than f->message_buf.
2061 (with_echo_area_buffer): Remove last two arguments. Update all callers.
2062 (set_message): Drop all but the second arg, which has to be a string.
2063 (set_message_1): Simplify now that we know that a1 is NULL and the
2064 second arg is a string.
2065 * frame.h (struct frame): Remove `message_buf' field.
2066 Use glyphs_initialized_p instead.
2067 (FRAME_MESSAGE_BUF): Remove macro.
2068 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
2069 * lisp.h (message2, message2_nolog): Remove declarations.
2070 (message3, message3_nolog): Update declarations.
2071 * keyboard.c (read_char_minibuf_menu_text)
2072 (read_char_minibuf_menu_width): Remove vars.
2073 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
2074 to correctly handle multibyte strings.
2075 * frame.c (delete_frame): Don't free message_buf any more.
2076 * editfns.c (message_text, message_length): Remove vars.
2077 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
2078 * fileio.c (auto_save_error): Use message3 instead of message2.
2079 * dispnew.c (adjust_frame_message_buffer): Remove function.
2081 2013-01-23 Eli Zaretskii <eliz@gnu.org>
2083 * w32term.c (w32fullscreen_hook): Account correctly for the screen
2084 real estate used for the tool bar and the menu bar.
2086 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
2088 * insdel.c (prepare_to_modify_buffer): Force redisplay if
2089 hidden buffer is prepared to modification (Bug#13164).
2091 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2093 * window.h (struct window): Change window_end_valid member from
2094 Lisp_Object to a bitfield. Adjust comments.
2095 (wset_window_end_valid): Remove.
2096 * window.c (adjust_window_count): Clear window_end_valid.
2097 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
2098 (Fwindow_line_height, set_window_buffer, Frecenter)
2099 (Fsplit_window_internal, Fdelete_other_windows_internal)
2100 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
2101 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
2102 * xdisp.c (check_window_end, reconsider_clip_changes)
2103 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
2104 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
2105 (find_first_unchanged_at_end_row, try_window_id): Likewise.
2107 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
2109 * xdisp.c (mark_window_display_accurate): Simplify the loop
2110 assuming that the only one of vchild, hchild or buffer window
2111 slots is non-nil. Call mark_window_display_accurate_1 for
2112 the leaf windows only.
2113 (mark_window_display_accurate_1): Always assume leaf window.
2116 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
2118 * emacs.c (Qkill_emacs_hook): Now static.
2120 * fileio.c (Finsert_file_contents): Simplify.
2121 Remove unnecessary assignments and tests.
2123 2013-01-21 Eli Zaretskii <eliz@gnu.org>
2125 * w32.c (acl_set_file): Don't test for errors unless
2126 set_file_security returns FALSE. Avoids spurious errors when
2129 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
2131 * fileio.c (Finsert_file_contents): Revert code introduced at
2132 2013-01-18 in favor of the simpler and generally better fix.
2133 Save stack space by removing 'buffer' and reusing 'read_buf'
2136 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2138 * lisp.h (eabs): Define unconditionally (Bug#13419).
2139 The old "#if !defined (eabs)" was an unnecessary revenant of back
2140 when this macro was called "abs". Document 'eabs' better.
2142 2013-01-19 Glenn Morris <rgm@gnu.org>
2144 * fns.c (Frandom): Doc fix.
2146 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2148 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
2149 segfault when there are lots of overlays.
2151 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
2152 when there are lots of overlays.
2153 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
2154 for the details and a way to reproduce.
2156 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2158 * fileio.c: Use O_APPEND to append.
2159 This corresponds better to the natural interpretation of "append",
2160 and avoids the need to open the output file twice, or to invoke
2161 lseek when APPEND is neither nil nor a number.
2162 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
2163 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
2164 file possibly twice, and lseeking to its end; this avoids the
2165 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
2166 at the same time: the combination is never needed and apparently
2167 it doesn't work with DOS_NT.
2169 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
2170 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
2172 Allow floating-point file offsets.
2173 Problem reported by Vitalie Spinu in
2174 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
2175 * fileio.c (emacs_lseek): Remove.
2176 (file_offset): New function.
2177 (Finsert_file_contents, Fwrite_region): Use it.
2179 2013-01-19 Chong Yidong <cyd@gnu.org>
2181 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
2182 aborting on Fsignal (Bug#13289).
2184 2013-01-19 Eli Zaretskii <eliz@gnu.org>
2186 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
2187 set_file_security as failure due to insufficient privileges.
2188 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2189 (fstat): Return owner and group like 'stat' and 'lstat' do.
2191 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
2193 Work around bug in CIFS and vboxsf file systems (Bug#13149).
2194 The bug was observed on Ubuntu operating inside a virtual machine,
2195 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
2196 The workaround introduces a race condition on non-buggy hosts,
2197 but it's an unlikely race and anyway there's a nearly identical
2198 nearby race that can't be fixed.
2199 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
2201 (Fwrite_region): Test for file system time stamp bug.
2202 (init_fileio): New function.
2203 * lisp.h (init_fileio): Declare it.
2204 * emacs.c (main): Call it.
2206 * fileio.c (Finsert_file_contents): Simplify new diagnostic
2207 and make it more consistent with other stat-failure diagnostics.
2209 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
2211 Fix crash when inserting data from non-regular files.
2212 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
2213 for the error description produced by valgrind.
2214 * fileio.c (read_non_regular): Rename to read_contents.
2215 Free Lisp_Save_Value object used to pass parameters.
2216 (read_non_regular_quit): Rename to read_contents_quit.
2217 (Finsert_file_contents): Redesign internal file reading loop to adjust
2218 gap and end positions after each read and so help make_gap to work
2219 properly. Do not signal an I/O error too early and so do not leave
2220 not yet decoded characters in a buffer, which was the reason of
2221 redisplay crash. Use list2 to build return value. Adjust comments.
2223 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
2225 Close a race when statting and reading files (Bug#13149).
2226 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
2227 This avoids a race if the file is renamed between stat and open.
2228 This race is not the problem originally noted in Bug#13149;
2229 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
2231 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>

2238 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
2239 * alloc.c (format_save_value): Rename to make_save_value.
2240 (make_save_pointer): New function.
2241 (record_xmalloc): Use make_save_pointer.
2242 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
2243 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
2244 Change users of make_save_value to make_save_pointer.
2245 Likewise for format_save_value and make_save_value.
2247 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
2249 * buffer.h (NARROWED, BUF_NARROWED): Drop unused macros.
2250 (DECODE_POSITION, BUFFER_CHECK_INDIRECTION): Fix indentation.

2254 2013-01-15 Paul Eggert <eggert@cs.ucla.edu>
2256 * alloc.c (free_save_value): Now static.
2258 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2260 * keymap.c (map_keymap_internal): Use format_save_value.
2261 (map_keymap_char_table_item): Adjust accordingly.
2262 * fileio.c (non_regular_fd, non_regular_inserted)
2263 (non_regular_nbytes): Remove.
2264 (Finsert_file_contents): Convert trytry to ptrdiff_t.
2265 Use format_save_value to pass parameters to read_non_regular.
2266 (read_non_regular): Use XSAVE_ macros to extract parameters.
2268 * xmenu.c (xmenu_show) [!USE_X_TOOLKIT && !USE_GTK]: Use
2270 (pop_down_menu) [!USE_X_TOOLKIT && !USE_GTK]: Adjust user.
2272 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2274 * lisp.h (XSAVE_POINTER, XSAVE_INTEGER): Change to allow
2275 extraction from any Lisp_Save_Value slot. Add type checking.
2276 * alloc.c, dired.c, editfns.c, fileio.c, ftfont.c, gtkutil.c:
2277 * keymap.c, lread.c, nsterm.h, nsmenu.c, xfns.c, xmenu.c:
2278 * xselect.c: All users changed.
2280 2013-01-15 Dmitry Antipov <dmantipov@yandex.ru>
2282 Some convenient bits to deal with Lisp_Save_Values.
2283 * lisp.h (XSAVE_OBJECT): New macro to extract saved objects.
2284 (allocate_misc): Remove prototype.
2285 (format_save_value): New prototype.
2286 * alloc.c (allocate_misc): Revert back to static.
2287 (format_save_value): New function to build Lisp_Save_Value
2288 object with the specified internal structure.
2289 (make_save_value): Reimplement using format_save_value.
2290 * editfns.c (save_excursion_save): Use format_save_value.
2291 (save_excursion_restore): Use XSAVE_OBJECT.
2293 2013-01-14 Paul Eggert <eggert@cs.ucla.edu>
2295 Avoid needless casts with XSAVE_POINTER.
2296 * alloc.c (mark_object) [GC_MARK_STACK]:
2297 * dired.c (directory_files_internal_unwind):
2298 * fileio.c (do_auto_save_unwind):
2299 * gtkutil.c (pop_down_dialog):
2300 * keymap.c (map_keymap_char_table_item):
2301 * lread.c (load_unwind):
2302 * nsmenu.m (pop_down_menu):
2303 * print.c (print_object) [GC_MARK_STACK]:
2304 * xfns.c (clean_up_file_dialog):
2305 * xmenu.c (cleanup_widget_value_tree):
2306 Omit casts between XSAVE_POINTER and a pointer type.
2308 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>
2310 Fix compilation with GC_MARK_STACK == GC_USE_GCPROS_AS_BEFORE.
2311 * eval.c (eval_sub): Protect `form' from being GCed before its
2312 car and cdr becomes protected with the backtrace entry.
2314 2013-01-14 Dmitry Antipov <dmantipov@yandex.ru>

2328 * editfns.c (save_excursion_save): Pack everything within
2329 Lisp_Save_Value and so avoid xmalloc.
2330 (save_excursion_restore): Adjust to match new layout. Use free_misc
2331 because we do not allocate extra memory any more. Add eassert.
2332 * print.c (print_object): New code to print Lisp_Save_Value. Do not
2333 rely on valid_lisp_object_p if !GC_MARK_STACK. Adjust comments.
2334 * dired.c, fileio.c, font.c, ftfont.c, gtkutil.c, keymap.c,
2335 * lread.c, nsmenu.m, nsterm.h, xfns.c, xmenu.c, xselect.c:

2345 2013-01-13 Paul Eggert <eggert@cs.ucla.edu>
2347 Fix SIGDANGER handlers, for AIX (Bug#13408).
2348 * sysdep.c.c (handle_danger_signal, deliver_danger_signal) [SIGDANGER]:
2349 Move handlers here from emacs.c; they were out of place.
2351 2013-01-11 Jan Djärv <jan.h.d@swipnet.se>
2353 * xterm.c (syms_of_xterm): Adjust documentation for
2354 scroll-bar-adjust-thumb-portion.

2401 2013-01-11 Dmitry Antipov <dmantipov@yandex.ru>
2403 Avoid unnecessary byte position calculation for the gap movement.
2404 Since all users of move_gap do CHAR_TO_BYTE for other purposes

2415 * lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal):
2417 * term.c (init_tty): Use them instead of rolling our own code.
2418 * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this
2419 switches from 'signal' to 'pthread_sigmask', which is safer in
2420 multithreaded applications.
2421 * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY,
2422 which has already arranged for that.
2423 (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY.
2424 This is the main part of the bug fix.

2433 Omit buffer_slot_type_mismatch and use generic predicates to enforce
2434 the type of per-buffer values where appropriate.
2435 * lisp.h (struct Lisp_Buffer_Objfwd): Rename slottype member to
2436 predicate, which is how it's really used now. Adjust comment.
2437 * buffer.h (buffer_slot_type_mismatch): Remove prototype.
2438 * buffer.c (buffer_slot_type_mismatch): Remove.
2439 (DEFVAR_PER_BUFFER, defvar_per_buffer): Rename type argument to
2440 predicate. Adjust comment.
2441 (syms_of_buffer): Use Qsymbolp for major-mode. Use Qintegerp for
2442 fill-column, left-margin, tab-width, buffer-saved-size,
2443 left-margin-width, right-margin-width, left-fringe-width,
2444 right-fringe-width, scroll-bar-width and buffer-display-count.
2445 Use Qstringp for default-directory, buffer-file-name,
2446 buffer-file-truename and buffer-auto-save-file-name. Use Qfloatp for
2447 scroll-up-aggressively and scroll-down-aggressively. Use Qnumberp for
2449 * data.c (store_symval_forwarding): Adjust to call the predicate.
2451 2013-01-09 Juanma Barranquero <lekktu@gmail.com>

2465 (make_gap_smaller): Use GAP_BYTES_MIN. Adjust comment.
2466 (make_gap_1): New function to adjust the gap of any buffer.
2467 * coding.c (coding_alloc_by_making_gap): Use it.
2468 * buffer.c (compact_buffer): Likewise. Use BUF_Z_BYTE, BUF_GAP_SIZE,
2469 GAP_BYTES_DFL and GAP_BYTES_MIN. Adjust comment.

2492 trailing dash is properly added.
2494 2013-01-05 Eli Zaretskii <eliz@gnu.org>
2496 * xdisp.c (dump_glyph): Align glyph data better. Use "pD" instead
2497 of a non-portable "t" to print ptrdiff_t values. Allow up to 9
2498 digits for buffer positions, before misalignment starts.
2499 Display "0" for integer "object" field.
2500 (dump_glyph_row): Adapt the header line to changes in dump_glyph.
2501 Display the newline glyph more unambiguously.
2503 2013-01-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2505 * nsterm.m (ns_draw_underwave):
2506 * w32term.c (w32_draw_underwave):
2507 * xterm.c (x_draw_underwave): Make underwave look more triangular
2508 and also degrade gracefully for small fonts. (Bug#13000)
2510 * nsterm.m (ns_draw_text_decoration):
2511 * w32term.c (x_draw_glyph_string):
2512 * xterm.c (x_draw_glyph_string): Don't use previous underline
2513 thickness and position if previous underline type is underwave.
2515 2013-01-04 Stefan Monnier <monnier@iro.umontreal.ca>
2517 * fileio.c (Ffile_acl): Undocument return format.
2519 2013-01-02 Glenn Morris <rgm@gnu.org>
2521 * keymap.c (Fkey_description): Doc fix. (Bug#13323)

2531 * lread.c (read_list):
2532 * minibuf.c (Ftry_completion):
2533 * term.c (tty_ins_del_lines):
2534 * xterm.c (x_draw_image_foreground, x_draw_image_foreground_1):
2535 Use eabs (x) rather than open-coding it as (x < 0 ? -x : x).
2537 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2539 * w32.c (unsetenv): Set up the string passed to _putenv
2541 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html
2542 for the bug this caused.
2544 2012-12-30 Paul Eggert <eggert@cs.ucla.edu>
2546 * coding.c (Qmac): Now static.
2548 2012-12-30 Jan Djärv <jan.h.d@swipnet.se>
2550 * gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
2551 (xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of

2558 by TOOLBAR_TOP_WIDGET.
2559 (xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
2560 Check toolbar_is_packed.
2561 (xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
2562 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2563 (xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
2565 (create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2566 (xg_update_menubar): Update title only if
2567 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2568 (xg_update_submenu): Skip tearoff only if
2569 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2570 (xg_initialize): Initialize xg_detached_menus only if
2571 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2573 * xterm.h (struct x_output): Surround handlebox_widget with
2574 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
2575 toolbar_in_hbox is bool.
2577 2012-12-30 Andreas Schwab <schwab@linux-m68k.org>
2579 * src/Makefile.in (TEMACS_LDFLAGS2): Remove.
2580 (LIBS_GNUSTEP): Define.
2581 (LIBES): Add $(LIBS_GNUSTEP).
2582 (temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).
2584 2012-12-30 Eli Zaretskii <eliz@gnu.org>
2586 * xdisp.c (set_cursor_from_row): Don't confuse a truncation or
2587 continuation glyph on a TTY with an indication of an empty line.
2590 2012-12-29 Eli Zaretskii <eliz@gnu.org>
2592 * fileio.c (Fset_file_selinux_context, Fset_file_acl): Return t if
2593 file's SELinux context or ACLs successfully set, nil otherwise.
2595 (Fcopy_file) [WINDOWSNT]: Improve diagnostics when CopyFile fails.

2598 SetEvent and WaitForSingleObject.
2600 2012-12-28 Paul Eggert <eggert@cs.ucla.edu>
2602 Port EXTERNALLY_VISIBLE to Clang 3.2.
2603 * conf_post.h (__has_attribute): New macro.
2604 (EXTERNALLY_VISIBLE): Use it. This ports to Clang 3.2.
2606 2012-12-27 Glenn Morris <rgm@gnu.org>
2608 * cygw32.c (Fcygwin_convert_file_name_to_windows)
2609 (Fcygwin_convert_file_name_from_windows): Doc fixes.
2611 2012-12-27 Eli Zaretskii <eliz@gnu.org>
2613 * fileio.c (file_name_as_directory, directory_file_name):
2614 Accept an additional argument MULTIBYTE to indicate whether the input C
2615 came from a multibyte or a unibyte Lisp string; all callers
2616 adjusted. Don't assume the input string is always multibyte.
2618 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2619 don't ENCODE_FILE them, and return a unibyte string if the input
2621 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2622 don't assume the input strings will always be multibyte. If the
2623 input strings are multibyte, decode strings obtained from C
2626 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2628 * lisp.h (toplevel): Add two notices to the comment about
2629 defining a new Lisp data type.

2633 * alloc.c (valid_lisp_object_p): Adjust comment.
2635 2012-12-26 Dmitry Antipov <dmantipov@yandex.ru>
2637 * keyboard.c (record_asynch_buffer_change): Initialize an event
2638 only if it's really needed.
2639 * frame.h (enum output_method): Remove output_mac member since
2640 it's a leftover from the deleted code.
2641 * frame.c (Fframep): Adjust user here ...
2642 * terminal.c (Fterminal_live_p): ... and here.
2643 * coding.c (Qmac): Now here because it's only used to denote
2644 end-of-line encoding type.
2645 (syms_of_coding): DEFSYM it.
2646 * frame.h (Qmac): Remove duplicated declaration.
2648 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2650 * window.c (select_window_1): Now static, since it's used only here.
2652 2012-12-25 Eli Zaretskii <eliz@gnu.org>
2654 * window.c (window_body_cols): Subtract display margins from the
2655 window body width on TTYs as well. See
2656 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2657 for the original report.
2659 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2661 * xdisp.c (redisplay_window): Remove inner local variable
2662 because the outer shadowed one has the same meaning.
2663 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2665 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2666 (xg_create_tool_bar): Adjust users.
2668 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2670 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2671 * buffer.c (Fget_buffer_create): Use it to set compact field of
2672 struct buffer_text to avoid accessing an uninitialized value
2673 when compact_buffer is called for the first time.
2674 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2675 (Fset_buffer_modified_p): Use buffer_window_count to check
2676 whether the buffer is displayed in some window.
2677 * xdisp.c (message_dolog): Likewise.
2679 2012-12-23 Eli Zaretskii <eliz@gnu.org>
2681 * w32.c (acl_set_file): If setting the file security descriptor
2682 fails, and the new DACL is identical to the existing one, silently
2683 return success. This fixes problems for users backing up their
2684 own files without having the necessary privileges for setting
2685 security descriptors.
2687 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2689 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2690 after WaitForSingleObject returns normally. This expedites reader
2691 thread shutdown when delete_child triggers it.
2692 (reap_subprocess): More accurate commentary for why we call
2693 delete_child only when cp->fd is negative.
2695 * w32.c (sys_close): Do not call delete_child on a subprocess
2696 whose handle is not yet closed. Instead, set its file descriptor
2697 to a negative value, so that reap_subprocess will call
2698 delete_child on that subprocess when its SIGCHLD arrives.
2699 This avoids closing handles used for communications between sys_select
2700 and reader_thread, which doesn't give sys_select a chance to
2701 notice that the process exited and invoke the SIGCHLD handler for
2704 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>
2706 * nsfns.m (Fns_do_applescript): Run event loop until script has
2707 been executed (Bug#12969).

2711 2012-12-22 Martin Rudalics <rudalics@gmx.at>
2713 * window.c (Fselect_window): Reword doc-string (Bug#13248).
2715 2012-12-22 Eli Zaretskii <eliz@gnu.org>
2717 * w32term.c (w32fullscreen_hook): New function.
2718 (w32_create_terminal): Plug it into the terminal's fullscreen_hook.
2720 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2722 * fileio.c (Finsert_file_contents): Doc fix.
2724 * w32proc.c (new_child, delete_child, find_child_pid): For a
2725 subprocess, consider its slot being in use as long as its process
2726 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2727 slot when a new process is started immediately after killing
2728 another one, without waiting enough time for the first process to
2729 be reaped and resources allocated for it be orderly freed.
2731 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2733 2012-12-21 Chong Yidong <cyd@gnu.org>
2735 * buffer.c (Fset_buffer_major_mode): Doc fix (Bug#13231).
2737 * fns.c (Fcompare_strings): Doc fix (Bug#13081).
2739 2012-12-21 Eli Zaretskii <eliz@gnu.org>
2741 * w32.c (get_name_and_id): Always pass NULL as the first argument
2742 of lookup_account_sid. Avoids crashes with UNC file names that
2743 refer to DFS domains, not to specific machine names. (Bug#12621)
2744 Remove now unused argument FNAME; all callers changed.
2745 (get_file_owner_and_group): Remove now unused argument FNAME; all
2748 2012-12-21 Chong Yidong <cyd@gnu.org>
2750 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2751 error for invalid chars, don't check for a nil return value.
2753 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2755 Avoid calls to CHAR_TO_BYTE if byte position is known.
2756 * editfns.c (make_buffer_string_both): Use move_gap_both.
2757 (Fbuffer_string): Use make_buffer_string_both.
2758 * marker.c (buf_charpos_to_bytepos): Convert to eassert.
2760 (buf_bytepos_to_charpos): Likewise.
2761 (charpos_to_bytepos): Remove.
2762 * fileio.c (Finsert_file_contents): Use move_gap_both.
2763 * search.c (Freplace_match): Likewise.
2764 * process.c (process_send_region): Likewise. Use convenient
2765 names for byte positions.
2766 * lisp.h (charpos_to_bytepos): Remove prototype.
2767 * indent.c (scan_for_column): Use CHAR_TO_BYTE.
2768 * insdel.c (move_gap): Likewise.

2774 2012-12-20 Stefan Monnier <monnier@iro.umontreal.ca>
2776 * xdisp.c (select_frame_for_redisplay, ensure_selected_frame): Remove.
2777 (redisplay_internal): Don't bother selecting the frame to get the
2778 proper value of frame-local variables (bug#13225).
2780 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2782 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2783 Rename 4th argument since it may be buffer or string. Adjust comment.
2784 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2786 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2788 * coding.c (Fdetect_coding_region): Do not check start and end with

2839 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2841 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2842 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2843 for some of that bug's symptoms can now cause Emacs to abort.
2844 Remove the workaround.
2845 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2846 The bug that caused SIGCHLD to get lost has been fixed, and the
2847 workaround for it can now cause Emacs to abort.
2849 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2851 * sysdep.c (emacs_abort): Bump backtrace size to 40.

2877 * w32proc.c (new_child): Initialize input_file and
2878 pending_deletion members of the child.

2891 * callproc.c (Fcall_process): Don't overwrite infile with result
2893 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2894 asynchronous subprocess, record the name of the input file name,
2896 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2897 delete the file, record it as pending deletion when the subprocess

2925 'lstat', which don't need that information, much faster.
2927 * dired.c (Ffile_attributes) [WINDOWSNT]:
2928 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2929 owner and group information from 'lstat'.
2931 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2933 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2934 as that confuses set-auto-coding, so insist on the head-read

2960 files, fixing a regression from 24.2.
2961 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2963 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2965 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2966 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2967 Remove unnecessary S_ISLNK test, as (contra the comments) this
2968 function can't copy symlinks. Improve quality of error message
2969 when attempting to copy files that are neither regular files nor

2988 * inotify.c (inotify_callback): Generate an Emacs event for every
2989 incoming inotify event.
2991 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2993 * xdisp.c (handle_face_prop): Fix logic of computing
2994 it->start_of_box_run_p.
2995 (append_space_for_newline): If the glyph row is R2L, reset the
2996 iterator's end_of_box_run_p flag before prepending the space glyph.

2998 iterator's start_of_box_run_p flag before prepending the stretch.

3263 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
3265 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
3267 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
3268 This will cause a production Emacs to dump core instead of
3271 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3273 * frame.c (make_frame): Do not set window's buffer to t.
3274 * window.c (Fsplit_window_internal): Likewise. Previously it was
3275 used to indicate that the window is being set up. Now we use
3276 set_window_buffer for all new windows, so the condition in ...
3277 (Fset_window_buffer): ... is always true and can be removed.
3279 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
3281 Convenient macro to check whether the buffer is hidden.
3282 * buffer.h (BUFFER_HIDDEN_P): New macro.
3283 * frame.c (make_frame): Use it. Adjust comment.
3284 * buffer.c (candidate_buffer): New function.
3285 (Fother_buffer, other_buffer_safely): Use it.
3287 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3289 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
3290 if the child process is still running. Instead, exit the wait
3291 loop and return zero. (Bug#13086)
3293 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3295 * frame.h (x_char_width, x_char_height): Remove prototypes.
3296 * w32term.h (x_char_width, x_char_height): Likewise.
3297 * xfns.c (x_char_width, x_char_height): Remove.

3299 * nsfns.c (x_char_width, x_char_height): Likewise.
3300 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
3302 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
3303 * keyboard.c (command_loop_1): Remove prototype.
3304 (command_loop_2, top_level_1): Add static to match prototype.
3306 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
3308 Fix a recently-introduced delete-process race condition.
3309 * callproc.c, process.h (record_kill_process):
3310 New function, containing part of the old call_process_kill.
3311 (call_process_kill): Use it.
3312 This does not change call_process_kill's behavior.
3313 * process.c (Fdelete_process): Use record_kill_process to fix a
3314 race condition that could cause Emacs to lose track of a child.
3316 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
3318 Avoid code duplication between prev_frame and next_frame.
3319 * frame.c (candidate_frame): New function. Add comment.
3320 (prev_frame, next_frame): Use it. Adjust comment.
3322 2012-12-06 Eli Zaretskii <eliz@gnu.org>
3324 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
3325 fails, signal an error instead of continuing with an empty
3327 Encode expanded temp file pattern before passing it to mkstemp or
3330 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
3331 Encode the file name before passing it to dostounix_filename, in
3332 case it will downcase it (under w32-downcase-file-names).
3335 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
3337 Minor call-process cleanups.
3338 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
3339 at the same time as other platforms, to simplify analysis.
3340 No need for fd0_volatile since we have synch_process_fd.
3341 Avoid needless emacs_close; arg is always negative.
3343 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
3345 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
3348 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
3350 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
3351 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
3352 and mouse_face_hidden members to a bitfields.
3353 * frame.h (struct frame): Remove set-but-not-used space_width member.
3354 (FRAME_SPACE_WIDTH): Remove.
3355 * nsterm.m, w32term.c, xterm.c: Adjust users.
3356 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
3357 member. Adjust users. Convert term_initted, delete_in_insert_mode,
3358 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
3359 members to a bitfields.
3361 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
3363 Don't let call-process be a zombie factory (Bug#12980).
3364 Fixing this bug required some cleanup of the signal-handling code.
3365 As a side effect, this change also fixes a longstanding rare race
3366 condition whereby Emacs could mistakenly kill unrelated processes,
3367 and it fixes a bug where a second C-g does not kill a recalcitrant
3368 synchronous process in GNU/Linux and similar platforms.
3369 The patch should also fix the last vestiges of Bug#9488,
3370 a bug which has mostly been fixed on the trunk by other changes.
3371 * callproc.c, process.h (synch_process_alive, synch_process_death)
3372 (synch_process_termsig, sync_process_retcode):
3373 Remove. All uses removed, to simplify analysis and so that
3374 less consing is done inside critical sections.
3375 * callproc.c (call_process_exited): Remove. All uses replaced
3376 with !synch_process_pid.
3377 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
3378 These take the role of what used to be in unwind-protect arg.
3380 (block_child_signal, unblock_child_signal):
3381 New functions, to avoid races that could kill innocent-victim processes.
3382 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
3383 (call_process_kill): Record killed processes as deleted, so that
3384 zombies do not clutter up the system. Do this inside a critical
3385 section, to avoid a race that would allow the clutter.
3386 (call_process_cleanup): Fix code so that the second C-g works again
3387 on common platforms such as GNU/Linux.
3388 (Fcall_process): Create the child process in a critical section,
3389 to fix a race condition. If creating an asynchronous process,
3390 record it as deleted so that zombies do not clutter up the system.
3391 Do unwind-protect for WINDOWSNT too, as that's simpler in the
3392 light of these changes. Omit unnecessary call to emacs_close
3393 before failure, as the unwind-protect code does that.
3394 * callproc.c (call_process_cleanup):
3395 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
3396 * process.c (record_deleted_pid): New function, containing
3397 code refactored out of Fdelete_process.
3398 (Fdelete_process): Use it.
3399 (process_status_retrieved): Remove. All callers changed to use
3400 child_status_change.
3401 (record_child_status_change): Remove, folding its contents into ...
3402 (handle_child_signal): ... this signal handler. Now, this
3403 function is purely a handler for SIGCHLD, and is not called after
3404 a synchronous waitpid returns; the synchronous code is moved to
3405 wait_for_termination. There is no need to worry about reaping
3406 more than one child now.
3407 * sysdep.c (get_child_status, child_status_changed): New functions.
3408 (wait_for_termination): Now takes int * status and bool
3409 interruptible arguments, too. Do not record child status change;
3410 that's now the caller's responsibility. All callers changed.
3411 Reimplement in terms of get_child_status.
3412 (wait_for_termination_1, interruptible_wait_for_termination):
3413 Remove. All callers changed to use wait_for_termination.
3414 * syswait.h: Include <stdbool.h>, for bool.
3415 (record_child_status_change, interruptible_wait_for_termination):
3417 (record_deleted_pid, child_status_changed): New decls.
3418 (wait_for_termination): Adjust to API changes noted above.
3420 * bytecode.c, lisp.h (Qbytecode): Remove.
3421 No longer needed after 2012-11-20 interactive-p changes.
3423 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3425 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3426 the scroll margin, move point outside the margin. (Bug#13055)
3428 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3430 * gtkutil.c (my_log_handler): New function.
3431 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3433 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3435 * lisp.h (modify_region): Rename to...
3436 (modify_region_1): ...new prototype.
3437 * textprop.c (modify_region): Now static. Adjust users.
3438 * insdel.c (modify_region): Rename to...
3439 (modify_region_1): ...new function to work with current buffer.
3440 Adjust comment and users. Use true and false for booleans.
3442 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3444 * alloc.c (free_save_value): New function.
3445 (safe_alloca_unwind): Use it.
3446 * lisp.h (free_save_value): New prototype.
3447 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3449 (save_excursion_restore): Adjust to match saved data structure.
3450 Use free_save_value to offload some work from GC. Drop obsolete
3453 2012-12-03 Chong Yidong <cyd@gnu.org>
3455 * fileio.c (Vauto_save_list_file_name): Doc fix.
3457 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3459 * w32fns.c: Remove prototype of atof.
3460 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3462 (file_dialog_callback): Make it UINT_PTR.
3464 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3467 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3468 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3471 2012-12-03 Glenn Morris <rgm@gnu.org>
3473 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3475 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3477 Fix xpalloc confusion after memory is exhausted.
3478 * alloc.c (xpalloc): Comment fix.
3479 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3480 and signals an error, do not clear charset_table_size, as
3481 charset_table is still valid.
3482 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3484 Use execve to avoid need to munge environ (Bug#13054).
3485 * callproc.c (Fcall_process):
3486 * process.c (create_process):
3487 Don't save and restore environ; no longer needed.
3488 * callproc.c (child_setup):
3489 Use execve, not execvp, to preserve environ.
3491 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3493 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3495 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3497 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3498 display for sliced images (Bug#10500).
3500 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3502 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3504 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3505 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3507 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3509 * xdisp.c (window_outdated): Remove eassert since it hits
3510 some suspicious corner cases (see Bug#13007 and Bug#13012).
3511 (mode_line_update_needed): New function.
3512 (redisplay_internal, redisplay_window): Use it.
3513 (ensure_selected_frame): New function.
3514 (redisplay_internal, unwind_redisplay): Use it.
3515 (redisplay_internal): Move comment about buffer_shared...
3516 (buffer_shared_and_changed): ...near to its real use.
3518 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3520 * callproc.c (Fcall_process): Don't misreport vfork failure.
3522 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3524 * callproc.c (Fcall_process): Fix vfork portability problems.
3525 Do not assume that fd[0], count, filefd, and save_environ survive
3526 vfork. Fix bug whereby wrong errno value could be reported for
3527 pipe failure. Some minor cleanups, too, as follows. Move buf and
3528 bufsize to the context where they're needed. Change new_argv to
3529 be of type char **, as this is more convenient and avoids casts.
3530 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3531 Now local constants, not macros.
3533 2012-11-18 Kenichi Handa <handa@gnu.org>
3535 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3536 for the variable "f".
3538 2012-11-13 Kenichi Handa <handa@gnu.org>
3540 * font.c (font_unparse_xlfd): Exclude special characters from the
3541 generating XLFD name.
3543 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3545 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

3547 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
3549 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

3556 * lread.c (readbyte_from_file): Assume EINTR is defined.
3557 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3558 Assume EIO and EAGAIN are defined.
3559 * unexcoff.c (write_segment): Assume EFAULT is defined.
3561 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3563 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3566 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3567 highlighting on the frame was cleared. Prevents assertion
3568 violations when repeatedly clicking on the "Top" link of the
3569 "bread-crumbs" in Info buffers.
3571 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>

3578 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3579 were always defined.
3581 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3583 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3584 between bpos_covered and bpos_max. This fixes cursor display when
3585 several display strings follow each other.
3587 * .gdbinit (pgx): If the glyph's object is a string, display the
3588 pointer to string data, rather than the value of the string object
3589 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3591 * indent.c (Fvertical_motion): If the starting position is covered
3592 by a display string, return to one position before that, to avoid
3593 overshooting it inside move_it_to. (Bug#12930)
3595 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>

3602 (set_frame_menubar): Adjust user.
3603 * w32term.h (struct x_output): Drop outdated #if 0 code.
3604 (struct w32_output): Use bitfields for explicit_parent,
3605 asked_for_visible and menubar_active members.
3606 Drop unused pending_menu_activation member.
3607 * xterm.h (struct x_output): Drop outdated #if 0 code.
3608 Use bitfields for explicit_parent, asked_for_visible,
3609 has_been_visible and net_wm_state_hidden_seen members.

3613 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3614 of a literal "/". (Bug#12955)
3615 (gl-stamp): Invoke fc.exe directly, not through cmd.
3617 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3619 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3620 * dired.c: Assume HAVE_DIRENT_H.
3621 (NAMLEN): Remove, replacing with ...
3622 (dirent_namelen): New function. All uses changed. Use the GNU macro
3623 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3624 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3625 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3626 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3628 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3629 * ndir.h: Rename to ../nt/inc/dirent.h.
3630 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3631 Do not include <dirent.h>; no longer needed.
3632 * w32.c: Include <dirent.h> rather than "ndir.h".
3634 2012-11-23 Chong Yidong <cyd@gnu.org>
3636 * xftfont.c (xftfont_open): Remove duplicate assignment.
3638 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3640 * alloc.c (Fgarbage_collect): Unblock input after clearing
3641 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3642 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3643 * msdos.c (IT_frame_up_to_date): Use it here...
3644 * w32term.c (w32_frame_up_to_date): ...here...
3645 * xterm.c (XTframe_up_to_date): ...and here...
3646 * nsterm.m (ns_frame_up_to_date): ...but not here.
3647 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3649 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3650 Do not check whether GC is in progress.
3652 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3654 * xdisp.c (window_buffer_changed): New function.
3655 (update_menu_bar, update_tool_bar): Use it to
3656 simplify large 'if' statements.
3657 (redisplay_internal): Generalize commonly used
3658 'tail' and 'frame' local variables.
3660 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3662 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3663 with Windows system header.
3665 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3667 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3668 * alloc.c: Assume unistd.h exists.
3669 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.

3673 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3674 * w32.h (getcwd): Remove decl.
3676 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>

3679 Make it set selected_window as well.
3680 (update_tool_bar): Use it.

3684 * emacs.c (main): Set the G_SLICE environment variable for all
3685 Cygwin builds, not just GTK builds. See
3686 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3688 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3690 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3691 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3692 Define for the MSVC compiler.
3694 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3696 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3697 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3698 dostounix_filename. Prevents crashes down the road, because
3699 dostounix_filename assumes it gets a unibyte string.
3700 Reported by Michel de Ruiter <michel@sentient.nl>, see

3712 (Ffmakunbound): Set to Qnil.
3713 (Fsymbol_function): Never signal an error.
3714 (Finteractive_form): Ignore Qunbound.
3716 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>

3725 decide whether all windows or frames should be updated.
3726 (window_outdated): New function.
3727 (text_outside_line_unchanged_p, redisplay_window): Use it.
3728 (redisplay_internal): Likewise. Fix indentation.
3730 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3732 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3733 (syms_of_eval): Remove corresponding defsubr.
3734 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3736 2012-11-19 Daniel Colascione <dancol@dancol.org>
3738 * w32fns.c (Fx_file_dialog):
3739 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3740 cygwin_convert_file_name*.
3742 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3743 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3745 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3747 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3749 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3751 * w32select.c: Include w32common.h before w32term.h, so that
3752 windows.h gets included before w32term.h uses some of its
3753 features, see below.
3755 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3757 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3759 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3761 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3763 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3764 (ns_select): Return at once if events are held (Bug#12834).
3766 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3768 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3769 Needed following 2012-10-20 change. (Bug#12902)
3771 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3773 * w32proc.c (waitpid): Remove unused label get_result.
3775 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3777 * makefile.w32-in (SYSWAIT_H): New macro.
3778 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3779 ($(BLD)/sysdep.$(O)): Update dependencies.
3781 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3783 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3784 * callproc.c (relocate_fd): Assume F_DUPFD.
3785 * emacs.c, term.c (O_RDWR): Remove.
3786 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3787 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3788 * nsterm.m: Assume <fcntl.h> exists.
3789 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3790 (create_pty, Fmake_network_process, server_accept_connection)
3791 (wait_reading_process_output, init_process_emacs):
3793 (wait_reading_process_output): Put in a special case for WINDOWSNT
3794 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3795 It's not clear this is needed, but it's a more-conservative change.
3796 (create_process): Assume FD_CLOEXEC.
3797 (create_process, create_pty): Assume O_NOCTTY.
3798 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3799 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3800 Omit if not DOS_NT, since F_GETFL is not defined there.
3801 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3802 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3804 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3805 lack it, since gnulib guarantees this.
3806 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3808 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3810 * w32.c (faccessat): Pretend that directories have the execute bit
3811 set. Emacs expects that, e.g., in files.el:cd-absolute.
3813 * w32proc.c (create_child): Don't clip the PID of the child
3814 process to fit into an Emacs integer, as this is no longer a
3816 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3817 reaping only the process specified by PID argument, if that is
3818 positive. Use PID instead of dead_child to know which process to
3819 reap. Wait for the child to die only if WNOHANG is not in
3821 (sys_select): Don't set dead_child.
3823 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3824 as it is no longer needed.
3826 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3828 (record_child_status_change): Remove the setting of
3829 record_at_most_one_child for the !WNOHANG case.
3831 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3833 Fix problems in ns port found by static checking.
3834 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3835 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3836 not to process group.
3837 (ns_select): Use emacs_write, not write, as that's more robust
3838 in the presence of signals.
3839 (fd_handler:): Check for read errors.
3841 2012-11-16 Glenn Morris <rgm@gnu.org>
3843 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3845 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3847 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3849 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3851 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3852 use the same value of thread handle.
3853 (start_timer_thread): If the timer thread exited (due to error),
3854 clean up by closing the two handles it used. Duplicate the caller
3855 thread's handle here, so it gets duplicated only once, when
3856 launching the timer thread. Set priority of the timer thread, not
3858 (getitimer): Don't duplicate the caller thread's handle here.
3861 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3863 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3866 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3868 Remove no-longer-used pty_max_bytes variable.
3869 * process.c (pty_max_bytes): Remove; unused.
3870 (send_process): Do not set it.
3872 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3874 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3875 Update dependencies.
3877 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3879 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3880 This follows up on the 2012-09-29 patch that removed indirection
3881 for the 'function' field. Reported by Sergey Vinokurov in
3882 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3884 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3886 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3887 different name, as the MS runtime does not have such a function,
3888 and probably never will.) All callers changed. Ignore DIRFD
3889 value if PATH is an absolute file name, to match Posix spec
3890 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3893 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3895 * xdisp.c (echo_area_display, redisplay_internal):
3896 Omit redundant check whether frame_garbaged is set.
3898 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3900 Use faccessat, not access, when checking file permissions (Bug#12632).
3901 This fixes a bug that has been present in Emacs since its creation.
3902 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3903 which must set some sort of record. (Torek's bug report was against
3904 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3905 same common flaw.) See Torek's Usenet posting
3906 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3907 Posted: Fri Apr 8 14:18:56 1983.
3908 * Makefile.in (LIB_EACCESS): New macro.
3910 * callproc.c (init_callproc):
3911 * charset.c (init_charset):
3912 * fileio.c (check_existing, check_executable, check_writable)
3914 * lread.c (openp, load_path_check):
3915 * process.c (allocate_pty):
3917 Use effective UID when checking permissions, not real UID.
3918 * callproc.c (init_callproc):
3919 * charset.c (init_charset):
3920 * lread.c (load_path_check, init_lread):
3921 Test whether directories are accessible, not merely whether they exist.
3922 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3923 * fileio.c (check_existing, check_executable, check_writable)
3925 Use symbolic names instead of integers for the flags, as they're
3927 (check_writable): New arg AMODE. All uses changed.
3928 Set errno on failure.
3929 (Ffile_readable_p): Use faccessat, not stat + open + close.
3930 (Ffile_writable_p): No need to call check_existing + check_writable.
3931 Just call check_writable and then look at errno. This saves a syscall.
3932 dir should never be nil; replace an unnecessary runtime check
3933 with an eassert. When checking the parent directory of a nonexistent
3934 file, check that the directory is searchable as well as writable, as
3935 we can't create files in unsearchable directories.
3936 (file_directory_p): New function, which uses 'stat' on most platforms
3937 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3938 (Ffile_directory_p, Fset_file_times): Use it.
3939 (file_accessible_directory_p): New function, which uses a single
3940 syscall for efficiency.
3941 (Ffile_accessible_directory_p): Use it.
3942 * xrdb.c (file_p): Use file_directory_p.
3943 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3944 * lread.c (openp): When opening a file, use fstat rather than
3945 stat, as that avoids a permissions race. When not opening a file,
3946 use file_directory_p rather than stat.
3947 (dir_warning): First arg is now a usage string, not a format.
3948 Use errno. All uses changed.
3949 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3950 that merely introduced a race.
3951 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3952 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3953 and similarly for the other O_* flags.
3954 * w32.c (sys_faccessat): Rename from sys_access and switch to
3955 faccessat's API. All uses changed.
3956 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3957 (magic_db): Rename from magic_file_p.
3958 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3959 char *, so that we don't have to test for file existence
3960 separately from opening the file for reading. This removes a race
3961 fixes a permission-checking problem, and simplifies the code.
3963 (file_p): Remove; no longer needed.
3965 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3967 Omit glyphs initialization at startup.
3968 * dispnew.c (glyphs_initialized_initially_p): Remove.
3969 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3970 (Fredraw_frame): Move actual code from here...
3971 (redraw_frame): ...to here. Add eassert. Adjust comment.
3972 (Fredraw_display): Use redraw_frame.
3973 * xdisp.c (clear_garbaged_frames): Likewise.
3975 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3977 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3978 passed to pint2str and pint2hrstr to be at most the size of the
3979 frame's decode_mode_spec_buffer. This avoids crashes with very
3980 large values of FIELD_WIDTH argument to decode_mode_spec.
3983 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3985 Fix a race with verify-visited-file-modtime (Bug#12863).
3986 Since at least 1991 Emacs has ignored an mtime difference of no
3987 more than one second, but my guess is that this was to work around
3988 file system bugs that were fixed long ago. Since the race is
3989 causing problems now, let's remove that code.
3990 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3991 whose time stamp is off by no more than a second. Insist that the
3992 file time stamps match exactly.
3994 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3996 * frame.h (struct frame): Convert external_tool_bar member to
3997 1-bit unsigned bitfield.
3998 * termhooks.h (struct terminal): Remove mouse_moved member since
3999 all users are long dead. Adjust comment on mouse_position_hook.
4001 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
4003 Simplify by using FOR_EACH_FRAME here and there.
4004 * frame.c (next_frame, prev_frame, other_visible_frames)
4005 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
4006 * w32term.c (x_window_to_scroll_bar): Likewise.
4007 * window.c (window_list): Likewise.
4008 * xdisp.c (x_consider_frame_title): Likewise.
4009 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
4010 * xfns.c (x_window_to_frame, x_any_window_to_frame)
4011 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
4012 * xmenu.c (menubar_id_to_frame): Likewise.
4013 * xselect.c (frame_for_x_selection): Likewise.
4014 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
4015 (x_window_to_menu_bar): Likewise.
4016 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
4018 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
4020 * data.c (Qdefalias_fset_function): Now static.
4022 Another tweak to vectorlike_header change.
4023 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
4024 Remove, and replace all uses with ...
4025 (next_in_free_list, set_next_in_free_list):
4026 New functions, which respect C's aliasing rules better.
4028 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
4030 * window.c (list4i): Rename from 'quad'. All uses changed.
4031 Needed because <sys/types.h> defines 'quad' on Solaris 10.
4033 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
4035 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
4036 warning about mixing declarations and code in ISO C90.
4038 2012-11-10 Martin Rudalics <rudalics@gmx.at>
4040 * window.c (Fsplit_window_internal): Set combination limit of
4041 new parent window to t iff Vwindow_combination_limit is t;
4042 fixing a regression introduced with the change from 2012-09-22.
4043 (Fset_window_combination_limit): Fix doc-string.
4045 2012-11-10 Eli Zaretskii <eliz@gnu.org>
4047 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
4048 amount when the scroll margins are too large. When scrolling
4049 backwards in the buffer, give up if cannot reach point or the
4050 scroll margin within a reasonable number of screen lines.
4051 Fixes point position in window under scroll-up/down-aggressively when
4052 point is positioned many lines beyond the window top/bottom.
4055 * ralloc.c (relinquish): If real_morecore fails to return memory
4056 to the system, don't crash; instead, leave the last heap
4057 unchanged and return. (Bug#12774)
4059 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4061 * lisp.h (AUTOLOADP): New macro.
4062 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
4063 * data.c (Ffset): Remove special ad-advice-info handling.
4064 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
4066 (Finteractive_form): Simplify.
4067 (Fquo): Don't insist on having at least 2 arguments.
4068 (Qdefalias_fset_function): New var.
4070 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4072 * image.c (xpm_make_color_table_h): Change to hashtest_equal.

4076 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
4078 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4080 Fix recently introduced crash on MS-Windows (Bug#12839).
4081 * w32term.h (struct scroll_bar): Use convenient header.
4082 (SCROLL_BAR_VEC_SIZE): Remove.
4083 * w32term.c (x_scroll_bar_create): Use VECSIZE.
4085 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
4087 Tweak last vectorlike_header change.
4088 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
4089 vectorlike object on the free list. This is introduced to avoid
4090 some (but not all) pointer casting and aliasing problems, see
4091 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
4092 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
4094 (xvectype, xvecsize): Use them to examine Lisp_Object values.
4096 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
4098 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
4099 been removed, so remove them here also.
4101 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
4103 * doc.c (Fdocumentation): Handle new property
4104 dynamic-docstring-function to replace the old ad-advice-info.
4106 2012-11-09 Paul Eggert <eggert@cs.ucla.edu>
4108 * fns.c (Qeql, hashtest_eq): Now static.
4110 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4112 * lisp.h (XHASH): Redefine to be imperfect and fit in a Lisp int.
4113 * fns.c (hashfn_eq, hashfn_eql, sxhash):
4114 * profiler.c (hashfn_profiler): Don't use XUINT on non-integers.
4115 * buffer.c (compare_overlays): Use XLI rather than XHASH.
4117 2012-11-08 Paul Eggert <eggert@cs.ucla.edu>
4119 Use same hash function for hashfn_profiler as for hash_string etc.
4120 * fns.c (SXHASH_COMBINE): Remove. All uses replaced by sxhash_combine.
4121 * lisp.h (sxhash_combine): New inline function, with the contents
4122 of the old SXHASH_COMBINE.
4123 * profiler.c (hashfn_profiler): Use it, instead of having a
4124 special hash function containing a comparison that always yields 1.
4126 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4128 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
4129 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
4130 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
4133 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
4135 * image.c (xpm_make_color_table_h): Fix compiler error because
4136 make_hash_table changed.
4138 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
4140 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
4142 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
4144 Use ad-hoc comparison function for the profiler's hash-tables.
4145 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
4146 (make_log): Use them.
4147 (handle_profiler_signal): Don't inhibit quit any longer since we don't
4148 call Fequal any more.
4149 (Ffunction_equal): New function.

4157 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
4158 (hash_lookup, hash_remove_from_table): Move assertion checking of
4159 hashfn result here. Check hash-equality before calling cmpfn.
4160 (Fmake_hash_table): Adjust call to make_hash_table.
4161 (hashtest_eq, hashtest_eql, hashtest_equal): New structs.

4169 2012-11-08 Eli Zaretskii <eliz@gnu.org>
4171 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
4172 value of w32-scroll-lock-modifier is neither nil nor one of the
4173 known key modifiers. (Bug#12806)
4175 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4177 Shrink struct vectorlike_header to the only size field.
4178 * lisp.h (enum pvec_type): Avoid explicit enum member values.
4180 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
4181 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
4182 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
4183 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
4184 information from the vector header. Adjust comment.
4185 (XSETPVECTYPE, XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR)
4186 (PSEUDOVECTOR_TYPEP, DEFUN): Adjust to match new vector header
4188 (XSETSUBR, SUBRP): Adjust to match new Lisp_Subr layout.
4189 (struct vectorlike_header): Remove next member. Adjust comment.
4190 (struct Lisp_Subr): Add convenient header. Adjust comment.
4191 (allocate_pseudovector): Adjust prototype.
4192 * alloc.c (mark_glyph_matrix, mark_face_cache, allocate_string)
4193 (sweep_string, lisp_malloc): Remove useless prototypes.
4194 (enum mem_type): Adjust comment.
4195 (NEXT_IN_FREE_LIST): New macro.
4196 (SETUP_ON_FREE_LIST): Adjust XSETPVECTYPESIZE usage.
4197 (Fmake_bool_vector): Likewise.
4198 (struct large_vector): New type to represent allocation unit for
4199 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
4200 (large_vectors): Change type to struct large_vector.
4201 (allocate_vector_from_block): Simplify.
4202 (PSEUDOVECTOR_NBYTES): Replace with...
4203 (vector_nbytes): ...new function. Adjust users.
4204 (sweep_vectors): Adjust processing of large vectors.
4205 (allocate_vectorlike): Likewise.
4206 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
4207 Add easserts. Adjust XSETPVECTYPESIZE usage.
4208 (allocate_buffer): Use BUFFER_PVEC_INIT.
4209 (live_vector_p): Adjust to match large vector.
4210 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
4211 * buffer.h (struct buffer): Add next member.
4212 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):
4214 (FOR_EACH_BUFFER): Adjust to match struct buffer change.
4215 * fns.c (internal_equal): Adjust to match enum pvec_type change.
4216 (copy_hash_table): Adjust to match vector header change.

4219 (xvectype): Likewise. Print PVEC_NORMAL_VECTOR for regular vectors.
4220 (xvecsize): New command.
4222 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
4224 * keyboard.c (event_to_kboard): Do not dereference
4225 frame_or_window field of SELECTION_REQUEST_EVENT
4226 and SELECTION_CLEAR_EVENT events (Bug#12814).
4227 * xterm.h (struct selection_input_event): Adjust comment.
4229 2012-11-07 Eli Zaretskii <eliz@gnu.org>
4231 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
4232 such as Scroll Lock, if the respective keys are treated as
4233 function keys, not as modifiers. This avoids destroying non-ASCII
4234 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
4236 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
4238 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
4240 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4242 Restore some duplicate definitions (Bug#12814).
4243 This undoes part of the 2012-11-03 changes. Some people build
4244 with plain -g rather than with -g3, and they need the duplicate
4245 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
4246 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
4247 Define as macros, as well as as enums or as constants.
4249 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
4251 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
4252 to keypad keys (Bug#12816).
4254 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
4256 Minor adjustments of recently-changed frame functions.
4257 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
4258 known to be a frame (we're in the FRAMEP branch).
4259 * lisp.h (Qframep): Remove decl. frame.h declares this.
4260 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
4261 since they're meant for Lisp fixnum values.
4263 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4265 * window.c (Fwindow_combination_limit): Revert to the only
4266 required argument and adjust docstring as suggested in
4267 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
4268 by Martin Rudalics <rudalics@gmx.at>.
4270 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4272 Widely used frame validity and checking functions.
4273 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
4274 * frame.c (decode_live_frame, decode_any_frame): New functions.
4275 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
4276 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
4277 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)
4278 (Fframe_pointer_visible_p): Use decode_any_frame.
4279 (Fmake_frame_visible, Fmake_frame_invisible, Ficonify_frame)
4280 (Fraise_frame, Flower_frame, Fmodify_frame_parameters)
4281 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
4282 (Fframe_focus): Likewise. Allow zero number of arguments.
4284 (frame_buffer_list, frame_buffer_predicate): Remove.
4285 * lisp.h (frame_buffer_predicate): Remove prototype.
4286 * buffer.c (Fother_buffer): Use decode_any_frame.
4287 * xdisp.c (Ftool_bar_lines_needed): Likewise.
4288 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
4289 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
4290 (Fclose_font, Ffont_info): Use decode_live_frame.
4291 * fontset.c (check_fontset_name): Likewise.
4292 * terminal.c (Fframe_terminal): Likewise.
4293 * w32fns.c (check_x_frame): Likewise.
4294 * window.c (Fminibuffer_window, Fwindow_at)
4295 (Fcurrent_window_configuration): Likewise.
4296 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
4297 Likewise. Allow zero number of arguments. Adjust docstring.
4298 * dispnew.c (Fredraw_frame): Likewise.
4299 * xfaces.c (frame_or_selected_frame): Remove.
4300 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
4301 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
4302 (Fframe_face_alist): Use decode_live_frame.
4303 * xfns.c (check_x_frame): Likewise.
4305 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
4307 * window.c (quad): New function.
4308 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
4309 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
4310 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
4311 (Fwindow_line_height): Use it.
4312 (Fwindow_fringes): Use list3.
4313 (Fwindow_scroll_bars): Use list4.
4314 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
4315 (Fwindow_combination_limit): Allow zero number of arguments.
4317 2012-11-05 Eli Zaretskii <eliz@gnu.org>
4319 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
4321 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
4322 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
4323 file descriptor 2 for standard error. (Bug#12805)
4325 2012-11-05 Chong Yidong <cyd@gnu.org>
4327 * process.c (wait_reading_process_output): Revert previous change.
4329 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
4331 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
4332 This removes code that has been obsolete since around 1990.
4333 * callproc.c (Fcall_process):
4335 * process.c (create_process):
4336 * term.c (dissociate_if_controlling_tty):
4337 Assume setsid exists.
4338 * callproc.c (child_setup): Assume setpgid exists and behaves as
4339 per POSIX.1-1988 or later.
4340 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
4341 * emacs.c (shut_down_emacs):
4342 * sysdep.c (sys_suspend, init_foreground_group):
4343 Assume getpgrp behaves as per POSIX.1-1998 or later.
4344 * msdos.c (setpgrp): Remove.
4345 (tcgetpgrp, setpgid, setsid): New functions.
4346 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
4347 * term.c (no_controlling_tty): Remove; unused.
4348 * w32proc.c (setpgrp): Remove.
4349 (setsid, tcgetpgrp): New functions.
4351 Simplify by assuming __fpending.
4352 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
4353 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
4354 Do not assume that __fpending's result fits in int.
4356 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
4358 Remove EMACS_OUTQSIZE+sleep hack.
4359 * dispnew.c (update_frame_1): Remove hack for terminals slower
4360 than 2400 bps, which throttled Emacs by having it sleep.
4361 This code hasn't worked since at least 2007, when the multi-tty stuff
4362 was added, and anyway those old terminals are long dead.
4363 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
4364 without the dispnew.c change, as dispnew.c doesn't include systty.h.
4366 Fix data-loss with --version (Bug#9574).
4367 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
4368 as we can't assume that emacs_strerror is initialized, and strerror
4369 is good enough here.
4370 (main): Invoke atexit earlier, to catch earlier instances of
4371 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
4373 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
4375 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
4376 (keyDown): Remap keypad keys to X11 virtual key codes.
4378 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
4380 Fix data-loss with --batch (Bug#9574).
4381 * emacs.c: Include <close-stream.h>.
4382 (close_output_streams): New function.
4383 (main): Pass it to atexit, so that Emacs closes stdout and stderr
4384 and handles errors appropriately.
4385 (Fkill_emacs): Don't worry about flushing, as close_output_stream
4388 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
4389 The symptom is a diagnostic "GLib-WARNING **: In call to
4390 g_spawn_sync(), exit status of a child process was requested but
4391 SIGCHLD action was set to SIG_IGN and ECHILD was received by
4392 waitpid(), so exit status can't be returned." The diagnostic
4393 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
4394 The real bug is a race condition between Emacs and glib: Emacs
4395 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
4396 so that glib can't find it. Work around the bug by invoking
4397 waitpid only on subprocesses that Emacs itself creates.
4398 * process.c (create_process, record_child_status_change):
4399 Don't use special value -1 in pid field, as the caller now must
4400 know the pid rather than having the callee infer it.
4401 The inference was sometimes incorrect anyway, due to another race.
4402 (create_process): Set new 'alive' member if child is created.
4403 (process_status_retrieved): New function.
4404 (record_child_status_change): Use it.
4405 Accept negative 1st argument, which means to wait for the
4406 processes that Emacs already knows about. Move special-case code
4407 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4408 processes that have already been waited for, by testing and
4409 clearing new 'alive' member.
4410 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4411 now does this internally.
4412 (handle_child_signal): Let record_child_status_change do all
4413 the work, since we do not want to reap all exited child processes,
4414 only the child processes that Emacs itself created.
4415 * process.h (Lisp_Process): New boolean member 'alive'.
4417 Omit duplicate definitions no longer needed with gcc -g3.
4418 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4419 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4420 Define only as macros. There's no longer any need to also define
4421 these symbols as enums or as constants, since we now assume
4422 gcc -g3 when debugging.
4424 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4426 * lisp.mk: Adjust comments to the fact that term/internal is now
4427 loaded from loadup.el.
4429 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4430 (msdos_fatal_signal): New function.
4431 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4434 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4435 for GCC versions before 4.
4436 (emacs_raise): Define to call msdos_fatal_signal.
4438 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4439 iterator when starting in the middle of a display or overlay
4442 2012-11-03 Chong Yidong <cyd@gnu.org>
4444 * process.c (wait_reading_process_output): Clean up the last
4447 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4449 * process.c (wait_reading_process_output): Avoid a race condition
4450 with SIGIO delivery (Bug#11536).
4452 2012-11-03 Chong Yidong <cyd@gnu.org>
4454 * buffer.c (cursor_type): Untabify docstring.
4456 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4458 * frame.h (struct frame): Drop can_have_scroll_bars member
4459 which is meaningless for a long time. Adjust comments.
4460 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4461 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4463 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4465 * window.c (decode_next_window_args): Update window arg after
4466 calling decode_live_window and so fix crash reported at
4467 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4468 by Juanma Barranquero <lekktu@gmail.com>.
4469 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4470 * font.c (Ffont_at): Likewise.
4472 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4474 * widget.c (resize_cb): New function.
4475 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4476 (EmacsFrameResize): Check if all is up to date before changing frame
4479 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4481 Implement backtrace output for fatal errors on MS-Windows.
4482 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4483 (BACKTRACE_LIMIT_MAX): New macro.
4484 (w32_backtrace): New function.
4485 (emacs_abort): Use w32_backtrace when the user chooses not to
4486 attach a debugger. Update the text of the abort dialog.
4488 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4490 Window-related stuff cleanup here and there.
4491 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4492 Use decode_any_window.
4493 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4494 * xdisp.c (Fformat_mode_line): Likewise.
4495 * font.c (Ffont_at): Use decode_live_window.
4496 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4497 * window.c (decode_next_window_args): Likewise.
4498 (decode_any_window): Remove static.
4499 * window.h (decode_any_window): Add prototype.
4500 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4501 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4504 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4506 Remove pad from struct input_event.
4507 * termhooks.h (struct input_event): Remove padding field.
4509 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4510 member is never cons for a long time. Adjust comment.
4511 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4512 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4513 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4514 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4516 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4518 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4520 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4522 Fix crash when using Emacs as commit editor for git (Bug#12697).
4523 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4524 and it is configured in conf_post.h.
4525 (Fcall_process): Don't invoke both setsid and setpgid; the former
4526 is enough, if it exists.
4527 * callproc.c (Fcall_process, child_setup):
4528 * process.c (create_process): Use setpgid.
4529 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4531 * dispnew.c (init_display): Initialize the foreground group
4532 if we are running a tty display.
4533 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4534 * lisp.h (init_foreground_group): New decl.
4535 * sysdep.c (inherited_pgroup): New static var.
4536 (init_foreground_group, tcsetpgrp_without_stopping)
4537 (narrow_foreground_group, widen_foreground_group): New functions.
4538 (init_sys_modes): Narrow foreground group.
4539 (reset_sys_modes): Widen foreground group.
4541 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4543 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4545 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4547 * minibuf.c (read_minibuf): Restore current buffer since
4548 choose_minibuf_frame calling Fset_frame_selected_window may
4549 change it (Bug#12766).
4551 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4553 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4555 2012-10-30 Kenichi Handa <handa@gnu.org>
4557 * font.c (Ffont_at): If WINDOW is specified and it is not
4558 displaying the current buffer, signal an error.
4560 2012-10-29 Daniel Colascione <dancol@dancol.org>
4562 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4563 In preparation for fixing bug#12739, move these functions from
4566 * coding.h, coding.c: ... to here, and compile them only when
4567 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4568 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4570 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4572 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4573 (timer_loop, getitimer, setitimer): Use it instead of
4574 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4576 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4579 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>
4581 * nsterm.m (NO_APPDEFINED_DATA): New define.
4582 (last_appdefined_event_data): New variable
4583 (last_appdefined_event): Remove.
4584 (ns_select): Initialize t from last_appdefined_event_data instead
4585 of [last_appdefined_event data1].
4586 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4587 remove last_appdefined_event (Bug#12698).
4589 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4591 * frame.c (x_set_font): Catch internal error.
4593 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4595 Avoid overflow in w32 implementation of interval timers.
4596 When possible, for ITIMER_PROF count only times the main thread
4598 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4599 'volatile ULONGLONG' types. All the other data which was
4600 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4601 (GetThreadTimes_Proc): New typedef.
4602 (w32_get_timer_time): New function, returns a suitable time value
4604 (timer_loop): Enter critical section when accessing ULONGLONG
4605 values of the itimer_data struct, as these accesses are no longer
4606 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4607 Remove unused variable.
4608 (init_timers): Initialize s_pfn_Get_Thread_Times.
4609 (start_timer_thread): Don't assign itimer->caller_thread here.

4616 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4617 mouse movement events if the menu bar is active. This avoids
4618 producing a busy "hour-glass" cursor by Windows if the mouse
4619 pointer is positioned over a tooltip shown for some menu item.
4621 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>

4669 (get_lface_attributes_no_remap, get_lface_attributes)
4670 (lface_fully_specified_p, x_supports_face_attributes_p)
4671 (tty_supports_face_attributes_p, face_fontset, realize_face)
4672 (realize_x_face, realize_tty_face):
4673 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4674 merely Lisp_Object *. This is more informative and avoids
4675 a warning on OpenBSD about accessing beyond an object's size.
4677 2012-10-20 Chong Yidong <cyd@gnu.org>

4706 (staticpro): If we run out of staticpro slots, die with an
4707 informative error instead of just calling emacs_abort.

5029 which is broken under remote desktop, calculate the number of

5088 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
5089 (w32_minor_version, w32_build_number, w32_subtype):
5090 Remove duplicate definitions.
5092 * w32fns.c: Include w32common.h; include w32heap.h only in
5095 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
5096 Use `report_file_error' instead of `error' in order to better
5097 inform users of what went wrong. Increase NTGUI_UNICODE file
5098 dialog box file name length to 32k, the maximum allowed by the NT
5101 * w32common.h: New file.
5102 (ROUND_UP, ROUND_DOWN, get_page_size)
5103 (get_allocation_unit, get_processor_type, get_w32_major_version)
5104 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
5105 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
5106 (OS_NT, os_subtype, cache_system_info): Move here.
5108 * unexw32.c, unexcw.c: Include w32common.h.
5110 * emacs.c (main): Use (defined (WINDOWSNT) || defined
5111 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
5112 to call syms_of_w32select.
5114 * cygw32.h: Remove obsolete EXFUN declarations.
5116 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
5118 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
5119 of w32inevt.o from SOME_MACHINE_OBJECTS.
5121 2012-10-08 Daniel Colascione <dancol@dancol.org>
5123 * image.c: Permanent fix for JPEG compilation issue --- limit
5124 jpeglib `boolean' redefinition to Cygwin builds.
5126 2012-10-08 Eli Zaretskii <eliz@gnu.org>
5128 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
5130 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
5133 2012-10-08 Daniel Colascione <dancol@dancol.org>
5135 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
5136 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
5137 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
5138 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
5139 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
5140 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
5141 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
5142 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
5143 now a supported configuration.
5145 * Makefile.in: consolidate image variables into LIBIMAGE; add
5146 W32_OBJ and W32_LIBS. Compile new files.
5149 (_DebPrint) declare tracing facility for W32 debugging. We need
5150 to unify tracing later.
5152 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
5153 unconditional use of W32 Unicode functions. Cygwin runs only on
5154 100% Unicode operating systems.
5156 * cygw32.c: New file. Define Cygwin-specific facilities.
5157 (Fcygwin_convert_path_to_windows)
5158 (Fcygwin_convert_path_from_windows): New user functions for
5159 accessing Cygwin path-munging routines.
5161 * cygw32.h: New file.
5162 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
5163 UTF-16LE strings temporarily inside non-Lisp-visible string
5166 (w32_strerror): Just what it says on the tin.
5168 * emacs.c: Make the NS fork-then-exec code for daemon-launching
5169 also run for Cygwin; both systems have the same problem with using
5170 GUI facilities in a forked child. Also call syms_of_cygw32,
5171 syms_of_w32select in correct places.
5173 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
5174 needs fork-then-exec for daemon launching.
5176 * font.h: Include frame.h.
5178 * image.c: Use the image library cache machinery only when we're
5179 compiling for native WINDOWSNT; Cygwin can use shared libraries
5180 like any other Unixlike system.
5182 * keyboard.c: Clarify a comment regarding the input loop.
5184 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
5185 functions directly instead of trying to detect at runtime that our
5186 host operating system supports them. We make this change for two
5187 reasons: Cygwin lacks support for the multibyte character
5188 conversion functions used by the legacy menu code, and Cygwin
5189 never needs to rely on non-Unicode APIs.
5191 * unexw32.c (hinst): Declare extern.
5193 * w32.c: Change header order;
5194 (w32_strerror): Move to w32fns.c because we need it for
5195 non-WINDOWSNT builds.
5197 * w32.h: Add #error macro to make sure we don't include w32.h for
5198 Cygwin builds. Remove w32select declarations.
5200 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
5201 w32fns.c. w32console.c is WINDOWSNT-only.
5203 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
5204 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
5206 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
5207 (w32_major_version, w32_minor_version, w32_build_number)
5208 (os_subtype, sound_type): Define here
5209 (w32_defined_color): Make color parameter const for consistency
5210 with other _defined_color functions.
5211 (w32_createwindow): Unconditionally call w32_init_class instead of
5212 doing so only when hprevinst is non-NULL. Plumbing hprevinst
5213 through the code is complex and unnecessary because class
5214 registration is practically free.
5215 (w32_name_of_message): New EMACSDEBUG-only function.
5216 (Fset_message_beep): Move here
5217 (Fx_open_connection): Require that the display name for Windows be
5218 "w32" for consistency, emacsclient disambiguation, and maybe, one
5219 day, multi-window-system support.
5220 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
5221 Cygwin files for W32 GUI facilities, since these clearly don't
5222 expect Cygwin names.
5223 (_DebPrint): Define.
5224 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
5225 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
5226 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
5227 (w32_last_error): Remove.
5229 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
5231 * w32heap.c (syspage_mask): Declare here.
5232 (cache_system_info): Remove.
5234 * w32inevt.c (faked_key): Define globally, not statically.
5235 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
5236 (w32_console_toggle_lock_key): Move to w32fns.c.
5238 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
5240 * w32proc.c (_DebPrint): Move to w32fns.c.
5241 * w32select.c: Include string.h, stdio.h for Cygwin.
5242 * w32select.h: New File.
5244 * w32term.c: Include io.h for non-CYGWIN builds; needed for
5246 (w32_message_fd): New variable. Under Cygwin, holds the file
5247 descriptor the system used to tell us about pending thread
5250 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
5251 that prevented compilation under non-WINDOWSNT systems.
5253 (w32_initialize): Open /dev/windows and assign it to
5254 w32_message_fd. Provide w32 feature.
5256 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
5257 (WM_EMACS_INPUT_READY): add.
5258 (prepend_msg, w32_message_fd): Declare globally.
5261 (keyboard_handle): Use only when WINDOWSNT.
5262 (notify_msg_ready): New function. Posts a message to the main
5263 thread's message queue under CYGWIN, which wakes up the main
5264 thread from select(2) by making the /dev/windows file descriptor
5265 ready. Under WINDOWSNT, it sets an event the same way the old
5268 (post, prepend_msg): Actually call notify_msg_ready instead of
5269 setting the input event directly.
5271 2012-10-07 Eli Zaretskii <eliz@gnu.org>
5273 * ralloc.c (relinquish): If a heap is ready to be relinquished,
5274 but it still has blocs in it, don't return it to the system,
5275 instead of aborting. (Bug#12402)
5277 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
5279 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
5281 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
5282 MAC_OS_X_VERSION_10_6.
5283 (syms_of_nsterm): Remove comment about Panther and above for
5285 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
5286 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
5287 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
5289 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
5290 MAC_OS_X_VERSION_10_4.
5292 * nsmenu.m (fillWithWidgetValue:): Remove code for <
5293 MAC_OS_X_VERSION_10_2.
5295 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
5297 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
5298 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
5300 * nsterm.m (ns_in_resize): Remove (Bug#12479).
5301 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
5302 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
5303 Remove ns_in_resize check.
5304 (ns_clear_frame_area): Remove resize handle code.
5306 * nsfns.m (ns_in_resize): Remove.
5307 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
5308 Remove ns_in_resize check.
5310 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
5312 Improve sys_siglist detection.
5313 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
5314 defined as a macro, as is done in Solaris.
5315 (sys_siglist_entries): New macro.
5316 (save_strsignal): Use it.
5317 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
5318 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
5320 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
5322 * nsfns.m (Fx_create_frame): Call x_default_parameter with
5323 fullscreen/Fullscreen.
5325 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
5326 tobar_height is new.
5328 * nsterm.m (x_make_frame_visible): Check for fullscreen.
5329 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
5330 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
5331 (windowDidResize:): Check for correct window if old style fullscreen.
5332 Capitalize word in comment. Remove incorrect comment.
5333 (initFrameFromEmacs:): tbar_height renamed tibar_height.
5334 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
5335 error in drawing background.
5336 (toggleFullScreen:): Remove comment. Rearrange calls.
5337 Set toolbar values to zero, save old height in tobar_height.
5338 Restore tool bar height when leaving fullscreen.
5339 (canBecomeMainWindow): New function.
5341 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
5343 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
5345 2012-10-05 Eli Zaretskii <eliz@gnu.org>
5347 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
5349 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
5350 that time stamps of directories could also be changed.
5351 Don't request the too broad GENERIC_WRITE, only the more restrictive
5352 FILE_WRITE_ATTRIBUTES access rights.
5354 * fileio.c (Fset_file_times): Special-case ignoring errors for
5355 directories only on MSDOS, not on MS-Windows.
5357 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
5359 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
5361 2012-10-04 Eli Zaretskii <eliz@gnu.org>
5363 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
5364 see whether CreateFile failed.
5366 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
5368 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
5369 to avoid similar races.
5370 * keyboard.c (pending_signals): Now bool, not int.
5372 Port timers to OpenBSD, plus check for timer failures.
5373 OpenBSD problem reported by Han Boetes.
5374 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
5376 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
5377 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
5378 like OpenBSD, which has timer_settime but does not declare it.
5379 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
5380 whether to use itimerspec-related primitives. All uses of
5381 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
5383 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5385 * profiler.c (handle_profiler_signal): Fix a malloc race
5386 that caused Emacs to hang on Fedora 17 when profiling Lisp.
5388 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
5390 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
5392 2012-10-02 Eli Zaretskii <eliz@gnu.org>
5394 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
5395 consistent with the change in return value of 'safe_strsignal'.
5397 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5399 Prefer plain 'static' to 'static inline' (Bug#12541).
5400 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5401 (bidi_set_sor_type, bidi_push_embedding_level)
5402 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5403 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5404 (bidi_cache_search, bidi_cache_ensure_space)
5405 (bidi_cache_iterator_state, bidi_cache_find)
5406 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5407 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5408 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5409 Now 'static', not 'static inline'.
5411 Count overruns when profiling; change units to ns.
5412 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5413 Give extra weight to samples after overruns, to attempt to count
5414 the time more accurately.
5415 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5416 the underlying primitives nominally do ns.
5417 (Fprofiler_cpu_start): Document the change. Mention that
5418 the sampling intervals are only approximate.
5420 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5422 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5424 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5425 case for the special 0 coding-system.
5427 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5428 (Fmake_overlay): Remove redundant tests.
5429 (fix_start_end_in_overlays): Remove redundant recentering.
5431 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5433 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5434 Update dependencies.
5436 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5438 Fix a malloc race condition involving strsignal.
5439 A signal can arrive in the middle of a malloc, and Emacs's signal
5440 handler can invoke strsignal, which can invoke malloc, which is
5441 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5442 Fix it by altering the signal handler so that it does not invoke
5444 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5445 * process.c (status_message): Use const pointer, in case strsignal
5446 is #defined to safe_strsignal.
5447 * sysdep.c (sys_siglist, init_signals): Always define and
5448 initialize a substitute sys_siglist if the system does not define
5449 one, even if HAVE_STRSIGNAL.
5450 (safe_strsignal): Rename from strsignal. Always define,
5451 using sys_siglist. Return a const pointer.
5452 * syssignal.h (safe_strsignal): New decl.
5453 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5455 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5457 * w32proc.c (timer_loop): Fix code that waits for timer
5458 expiration, to avoid high CPU usage.
5460 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5462 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5463 (sweep_weak_table): Remove redundant prototypes.
5465 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5467 * emacs.c: Move the inclusion of TERM_HEADER after including
5468 windows.h on WINDOWSNT. This avoids compilation problems with
5471 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5473 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5474 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5475 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5476 as the previous version used 'void *'.
5478 * ralloc.c (ROUNDUP): Fix last change.
5479 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5482 * w32proc.c <disable_itimers>: New static flag.
5483 (init_timers): Initialize it to zero, after creating the critical
5484 sections used by the timer threads.
5485 (term_timers): Set to 1 before deleting the critical sections.
5486 (getitimer, setitimer): If disable_itimers is non-zero, return an
5487 error indication without doing anything. Reported by Fabrice
5488 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5489 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5491 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5494 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5495 term_ntproc after all the other bookkeeping, to get timers working
5496 as long as possible.
5498 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5500 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5501 Suggested by Juri Linkov in
5502 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5504 Prefer plain 'static' to 'static inline' (Bug#12541).
5505 With static functions, modern compilers inline pretty well by
5506 themselves; advice from programmers often hurts as much as it helps.
5507 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5508 this change shrinks the text size of the Emacs executable by 1.1%
5509 without affecting CPU significantly in my benchmark.
5510 * alloc.c (mem_find, live_string_p, live_cons_p, live_symbol_p)
5511 (live_float_p, live_misc_p, live_vector_p, live_buffer_p)

5808 for consistency with other handlers.
5809 (setup_cpu_timer): New function, with much of what used to be in

5811 Prefer timer_settime if available, and prefer
5812 thread cputime clocks, then process cputime clocks, then
5813 monotonic clocks, to the old realtime clock. Use make_timeval
5814 to round more-correctly when falling back to setitimer.
5815 (Fprofiler_cpu_start): Use it.
5816 (Fprofiler_cpu_stop): Prefer timer_settime if available.

6034 Move pid_t related decls out of lisp.h.
6035 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
6036 (interruptible_wait_for_termination):
6037 Move these decls from lisp.h to syswait.h, since they use pid_t.
6038 Needed on FreeBSD; see Herbert J. Skuhra in
6039 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.

6086 2012-09-23 Eli Zaretskii <eliz@gnu.org>
6088 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
6089 fatal_error_backtrace.
6091 * w32proc.c (sys_kill): Undo last change: don't do anything when
6092 invoked to deliver SIGABRT to our own process. This is now
6093 handled by emacs_raise.
6095 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
6097 * w32term.c (w32_read_socket): Remove leftover reference to
6098 interrupt_input_pending.
6100 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6102 Do not use SA_NODEFER.
6103 Problem reported by Dani Moncayo in
6104 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
6106 * sysdep.c (emacs_abort): Do not reset signal handler.
6107 * emacs.c (terminate_due_to_signal): Reset signal handler here.
6108 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
6109 wanted even on POSIXish hosts, and it doesn't work on Windows.
6111 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6113 * xterm.c (x_term_init): Call fixup_locale before and after calling
6114 gtk_init (Bug#12392).
6116 2012-09-23 Chong Yidong <cyd@gnu.org>
6118 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
6119 Vdynamic_library_alist.
6121 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
6122 (Fgnutls_available_p): Caller changed.
6124 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
6125 (Flibxml_parse_xml_region): Likewise.
6127 * dispextern.h (struct image_type): Remove arg from init function.
6129 * image.c (Finit_image_library, lookup_image_type)
6130 (define_image_type): Remove now-unneeded second arg.
6131 (init_xpm_functions, init_png_functions, init_jpeg_functions)
6132 (init_tiff_functions, init_gif_functions, init_svg_functions):
6133 Arglist and w32_delayed_load calling convention changed.
6134 (gs_type): Remove init_gs_functions; there is no such function.
6135 (valid_image_p, make_image): Fix caller to lookup_image_type.
6137 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
6139 Simplify and avoid signal-handling races (Bug#12471).
6141 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
6142 Avoid recursive loop if there's a fatal error in the function itself.
6143 * atimer.c (pending_atimers):
6144 * blockinput.h: Don't include "atimer.h"; no longer needed.
6145 (interrupt_input_pending): Remove. All uses removed.
6146 pending_signals now counts both atimers and ordinary interrupts.
6147 This is less racy than having three separate pending-signal flags.
6148 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
6150 Rename from their upper-case counterparts BLOCK_INPUT,
6151 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
6152 INPUT_BLOCKED_P, and turn into functions. All uses changed.
6153 This makes it easier to access volatile variables more accurately.
6154 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
6155 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
6156 that's more reliable if the code is buggy and sets
6157 interrupt_input_blocked to a negative value. All uses changed.
6158 * atimer.c (deliver_alarm_signal):
6159 Remove. No need to deliver this to the parent; any thread can
6160 handle this signal now. All uses replaced by underlying handler.
6161 * atimer.c (turn_on_atimers):
6162 * dispnew.c (handle_window_change_signal):
6163 * emacs.c (handle_danger_signal):
6164 * keyboard.c (kbd_buffer_get_event):
6165 Don't reestablish signal handler; not needed with sigaction.
6166 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
6168 Rework to avoid unnecessary accesses to volatile variables.
6169 (UNBLOCK_INPUT_TO): Now a function.
6170 (totally_unblock_input, unblock_input): New decls.
6171 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
6172 (init_data): Remove. Necessary stuff now done in init_signal.
6173 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
6174 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
6175 (fatal_error_code): Remove; no longer needed.
6176 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
6177 it doesn't always backtrace. All uses changed. No need to reset
6178 signal to default, since sigaction and/or die does that for us now.
6179 Use emacs_raise (FOO), not kill (getpid (), FOO).
6180 (main): Check more-accurately whether we're dumping.
6181 Move fatal-error setup to sysdep.c
6182 * floatfns.c: Do not include "syssignal.h"; no longer needed.
6183 * gtkutil.c (xg_get_file_name, xg_get_font):
6184 Remove no-longer-needed signal-mask manipulation.
6185 * keyboard.c, process.c (POLL_FOR_INPUT):
6186 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
6187 * keyboard.c (read_avail_input): Remove.
6188 All uses replaced by gobble_input.
6189 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
6190 (kbd_buffer_store_event_hold, gobble_input):
6191 (record_asynch_buffer_change) [USABLE_SIGIO]:
6192 (store_user_signal_events):
6193 No need to mess with signal mask.
6194 (gobble_input): If blocking input and there are terminals, simply
6195 set pending_signals to 1 and return. All hooks changed to not
6196 worry about whether input is blocked.
6197 (process_pending_signals): Clear pending_signals before processing
6198 them, in case a signal comes in while we're processing.
6199 By convention callers now test pending_signals before calling us.
6200 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
6201 New functions, to support changes to blockinput.h.
6202 (handle_input_available_signal): Now extern.
6203 (reinvoke_input_signal): Remove. All uses replaced by
6205 (quit_count): Now volatile, since a signal handler uses it.
6206 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
6207 All callers changed. Block SIGINT only if not already blocked.
6208 Clear sigmask reliably, even if Fsignal returns, which it can.
6209 Omit unnecessary accesses to volatile var.
6210 (quit_throw_to_read_char): No need to restore sigmask.
6211 * keyboard.c (gobble_input, handle_user_signal):
6212 * process.c (wait_reading_process_output):
6213 Call signal-handling code rather than killing ourselves.
6214 * lisp.h: Include <float.h>, for...
6215 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
6216 (pending_signals): Now volatile.
6217 (syms_of_data): Now const if IEEE floating point.
6218 (handle_input_available_signal) [USABLE_SIGIO]:
6219 (terminate_due_to_signal, record_child_status_change): New decls.
6220 * process.c (create_process): Avoid disaster if memory is exhausted
6221 while we're processing a vfork, by tightening the critical section
6223 (send_process_frame, process_sent_to, handle_pipe_signal)
6224 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
6226 (send_process): No need for setjmp/longjmp any more, since the
6227 SIGPIPE stuff is now gone. Instead, report an error if errno
6229 (record_child_status_change): Now extern. PID and W are now args.
6230 Return void, not bool. All callers changed.
6231 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
6232 Remove. All uses removed. This bug should be fixed now in a
6234 (wait_for_termination_1): Use waitpid rather than sigsuspend,
6235 and record the child status change directly. This avoids the
6236 need to futz with the signal mask.
6237 (process_fatal_action): Move here from emacs.c.
6238 (emacs_sigaction_flags): New function, containing
6239 much of what used to be in emacs_sigaction_init.
6240 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
6241 caught by emacs, to make races less likely.
6242 (deliver_process_signal): Rename from handle_on_main_thread.
6244 (BACKTRACE_LIMIT_MAX): Now at top level.
6245 (thread_backtrace_buffer, threadback_backtrace_pointers):
6247 (deliver_thread_signal, deliver_fatal_thread_signal):
6248 New functions, for more-accurate delivery of thread-specific signals.
6249 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
6250 (deliver_arith_signal): Handle in this thread, not
6251 in the main thread, since it's triggered by this thread.
6252 (maybe_fatal_sig): New function.
6253 (init_signals): New arg DUMPING so that we can be more accurate
6254 about whether we're dumping. Caller changed.
6255 Treat thread-specific signals differently from process-general signals.
6256 Block all signals while handling fatal error; that's safer.
6257 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
6259 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
6260 Ignore SIGPIPE unless batch.
6261 (emacs_backtrace): Output backtrace for the appropriate thread,
6262 which is not necessarily the main thread.
6263 * syssignal.h: Include <stdbool.h>.
6264 (emacs_raise): New macro.
6265 * xterm.c (x_connection_signal): Remove; no longer needed
6266 now that we use sigaction.
6267 (x_connection_closed): No need to mess with sigmask now.
6268 (x_initialize): No need to reset SIGPIPE handler here, since
6269 init_signals does this for us now.
6271 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
6273 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
6274 background rect may be larger (Bug#12245).
6276 2012-09-23 Chong Yidong <cyd@gnu.org>
6278 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
6280 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6282 * .gdbinit: Just stop at fatal_error_backtrace.
6283 See Stefan Monnier's request in
6284 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
6285 Remove no-longer-used query of system type.
6287 2012-09-22 Chong Yidong <cyd@gnu.org>
6289 * search.c (Freplace_match): Doc fix (Bug#12325).
6291 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
6293 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
6294 (Fline_end_position): Doc fix.
6296 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
6298 2012-09-22 Chong Yidong <cyd@gnu.org>
6300 * dispextern.h (struct image_type): Add new slot, storing a type
6301 initialization function.
6303 * image.c (define_image_type): Call the image initializer function
6304 if it is defined. Arguments and return value changed.
6305 (valid_image_p, make_image): Callers changed.
6306 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
6307 (gif_type, imagemagick_type, svg_type, gs_type):
6308 Add initialization functions.
6309 (Finit_image_library): Call lookup_image_type.
6310 (CHECK_LIB_AVAILABLE): Macro deleted.
6311 (lookup_image_type): Call define_image_type here, rather than via
6312 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
6313 (syms_of_image): Move define_image_type calls for xbm_type and
6314 pbm_type to lookup_image_type.
6316 2012-09-22 Eli Zaretskii <eliz@gnu.org>
6318 * keyboard.c (timer_check_2): Move calculation of 'timers' and
6319 'idle_timers' from here ...
6320 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
6321 lists, to avoid infloops when the timer does something stupid,
6322 like reinvoke itself with the same or smaller time-out.
6325 2012-09-22 Martin Rudalics <rudalics@gmx.at>
6327 * window.c (Fsplit_window_internal): Handle only Qt value of
6328 Vwindow_combination_limit separately.
6329 (Qtemp_buffer_resize): New symbol.
6330 (Vwindow_combination_limit): New default value.
6333 2012-09-22 Eli Zaretskii <eliz@gnu.org>

6336 the new overlay string. (Bug#10159)
6338 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
6340 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
6341 or that fprintf is async-signal-safe. POSIX doesn't require
6344 2012-09-22 Chong Yidong <cyd@gnu.org>
6346 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
6349 2012-09-22 Kenichi Handa <handa@gnu.org>
6351 * composite.c (composition_reseat_it): Handle the case that a
6352 grapheme cluster is not covered by a single font (Bug#12352).
6354 2012-09-21 Chong Yidong <cyd@gnu.org>
6356 * image.c (define_image_type): Avoid adding duplicate types to
6357 image_types (Bug#12463). Suggested by Jörg Walter.
6359 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6361 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
6362 (print_load_command_name): Add case LC_DATA_IN_CODE.
6363 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.

6367 * eval.c (Frun_hook_with_args_until_success)
6368 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
6370 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
6372 * fileio.c (Ffile_selinux_context): Only call freecon when
6373 lgetfilecon succeeded.
6374 (Fset_file_selinux_context): Likewise. (Bug#12444)
6376 2012-09-21 Eli Zaretskii <eliz@gnu.org>
6378 * xdisp.c (try_window_reusing_current_matrix): Under bidi
6379 reordering, locate the cursor by calling set_cursor_from_row; if
6380 that fails, clear the desired glyph matrix before returning a
6381 failure indication to the caller. Fixes leaving garbled display
6382 when fast scrolling with a down-key. (Bug#12403)
6383 (compute_stop_pos_backwards): Fix a typo that caused crashes while
6384 scrolling through multibyte text.
6386 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
6388 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
6389 calling mark_vectorlike since that's the one that marks the window.
6390 (mark_discard_killed_buffers): Mark the final cdr.
6391 * window.h (struct window): Move prev/next_buffers to the
6392 non-standard fields.
6393 * window.c (make_window): Initialize prev/next_buffers manually.
6395 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
6397 Omit unused arg EXPECTED from socket hooks.
6398 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6399 * nsterm.m (ns_term_init):
6400 * termhooks.h (struct terminal.read_socket_hook):
6401 * w32inevt.c (w32_console_read_socket):
6402 * w32term.c (w32_read_socket):
6403 * xterm.c (XTread_socket):
6404 Omit unused arg EXPECTED. All callers changed.
6405 (store_user_signal_events): Return void, not int, since callers no
6406 longer care about the return value. All uses changed.
6408 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6410 * w32gui.h (XParseGeometry): Do not declare.
6412 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6414 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6415 Ignore 'expected'. See Eli Zaretskii in

6418 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6419 (XParseGeometry): Now static. Substitute extremal values for
6420 values that are out of range.
6422 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6424 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6426 * nsfns.m (XParseGeometry): Remove.
6427 (Fx_create_frame): Call x_set_offset to correctly interpret
6428 top_pos in geometry.
6430 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6431 (Fx_parse_geometry): If there is a space in string, call
6432 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6434 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6436 * search.c (scan_buffer): Use character positions in calls to
6437 region_cache_forward and region_cache_backward, not byte
6438 positions. (Bug#12196)
6440 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6441 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6443 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6444 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6445 emacs_blocked_malloc, now deleted.
6447 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6449 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6450 The workaround was for improving performance on Solaris 2.4, but
6451 is getting in the way now. Emacs will still work if someone is
6452 still running Solaris 2.4 in a museum somewhere; Sun dropped
6453 support for Solaris 2.4 in 2003.
6454 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6455 * process.c (create_process) [HAVE_WORKING_VFORK]:
6456 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6457 since Emacs no longer uses vfork on that platform.
6459 2012-09-17 Glenn Morris <rgm@gnu.org>
6461 * emacs.c: Use COPYRIGHT.
6463 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6465 Remove configure's --without-sync-input option (Bug#12450).
6466 When auditing signal-handling in preparation for cleaning it up,
6467 I found that SYNC_INPUT has race conditions and would be a real
6468 pain to fix. Since it's an undocumented and deprecated
6469 configure-time option, now seems like a good time to remove it.
6470 Also see <http://bugs.gnu.org/11080#16>.
6471 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6472 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6473 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6474 (malloc_hysteresis):
6475 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6476 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6477 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6478 (dont_register_blocks, bytes_used_when_reconsidered)
6479 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6480 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6481 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6482 Remove. All uses removed.
6483 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6484 implementation, one that depends on whether the new macro
6485 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6487 * atimer.c (run_timers, handle_alarm_signal):
6488 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6489 (handle_async_input, process_pending_signals)
6490 (handle_input_available_signal, init_keyboard):
6491 * nsterm.m (ns_read_socket):
6492 * process.c (wait_reading_process_output):
6493 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6494 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6496 * xterm.c (XTread_socket):
6498 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6499 * eval.c (handling_signal): Remove. All uses removed.
6500 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6501 All uses replaced with the SYNC_INPUT version.
6502 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6504 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6507 * font.c (Ffont_shape_gstring): Remove unused local.
6509 2012-09-16 Glenn Morris <rgm@gnu.org>
6511 * Makefile.in (clean): No longer run nextstep's clean.
6513 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6515 (ns-app): Move here from ns.mk, and simplify.
6516 (clean): Simplify nextstep entry.
6517 * ns.mk: Remove file.
6519 2012-09-17 Kenichi Handa <handa@gnu.org>
6521 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6522 not covert the last few charactes.
6524 2012-09-16 Kenichi Handa <handa@gnu.org>
6526 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6527 here, but just check the validity of glyphs in the glyph-string.
6529 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6531 * window.c (Fwindow_parameter, Fset_window_parameter):
6532 Accept any window as argument (Bug#12452).
6534 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6536 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6537 to ns_term_init to avoid memory leak.
6539 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6540 explicit retain/release.
6541 (ns_term_init): Only allow one display. Initialize outerpool and
6544 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6546 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6547 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6548 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6549 the Microsoft problem in a different way, by altering ../nt/config.nt.
6551 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6566 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6567 by lisp.h. This completes removal of setjmp.h inclusion
6568 erroneously announced in the previous commit. (Bug#12446)
6570 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6573 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6574 not defined as a macro. The latter happens on MS-Windows.
6577 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6579 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6580 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6581 Some instances of '#include <setjmp.h>' removed, if the
6582 only reason for the instance was because "lisp.h" was included.
6583 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6584 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6585 and _longjmp with the new symbols. Emacs already uses _setjmp if
6586 available, so this change affects only POSIXish hosts that have
6587 sigsetjmp but not _setjmp, such as some versions of Solaris and
6588 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6589 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6590 (png_load_body) [HAVE_PNG]:
6591 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6592 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6593 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6594 since PNG requires jmp_buf. This is the only exception to the
6595 general rule that we now use sys_setjmp and sys_longjmp.
6596 This exception is OK since this code does not change the signal
6597 mask or longjmp out of a signal handler.
6599 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6601 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6602 Include "syssignal.h", for 'main_thread'.
6604 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6606 Avoid out-of-range marker position (Bug#12426).
6607 * insdel.c (replace_range, replace_range_2):
6608 Adjust markers before overlays, as suggested by comments.
6609 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6610 Remove redundant check before calling offset_intervals.
6612 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6614 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6615 current buffer (Bug#12387).
6617 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6619 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6621 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6623 Use a more backwards-compatible timer format (Bug#12430).
6624 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6625 vector element, not from the 4th, since PSECS is now at the end.
6626 (Fcurrent_idle_time): Doc fix.
6628 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6630 Function to mark objects and remove killed buffers at once.
6631 * alloc.c (discard_killed_buffers): Rename to ...
6632 (mark_discard_killed buffers) ... new name. Add marking
6633 of remaining objects. Fix comment. Adjust users.
6634 (mark_object): Do not touch frame buffer lists here.
6635 * frame.c (delete_frame): Reset frame buffer lists here.
6637 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6639 Better workaround for GNOME bug when --enable-gcc-warnings.
6640 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6641 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6642 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6644 Simplify SIGIO usage (Bug#12408).
6645 The code that dealt with SIGIO was crufty and confusing, e.g., it
6646 played tricks like "#undef SIGIO" but these tricks were not used
6647 consistently. Simplify mostly by not #undeffing standard symbols,
6648 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6649 or not as we please) rather than "defined SIGIO" (standard symbol
6650 that we probably shouldn't #undef).
6651 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6652 Modules that need it can include it.
6653 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6654 * dispextern.h (ignore_sigio): New decl.
6655 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6656 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6657 * emacs.c (shut_down_emacs):
6658 * keyboard.c (kbd_buffer_store_event_hold):
6659 Use ignore_sigio rather than invoking 'signal' directly.
6660 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6662 (FIONREAD, SIGIO): Do not #undef.
6663 (tty_read_avail_input): Use #error rather than a syntax error.
6664 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6665 for I_PIPE, used by SETUP_SLAVE_PTY.
6666 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6667 * sysdep.c (croak): Remove; no longer needed. This bit of
6668 temporary code, with Fred N. Fish's comment that it's temporary,
6669 has been in Emacs since at least 1992!
6670 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6671 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6672 * syssignal.h (croak): Remove decl.
6673 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6674 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6675 now that we're termios-only.
6676 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6677 * term.c (dissociate_if_controlling_tty): Use #error rather than
6680 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6681 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6682 to work around GNOME bug 683906.
6683 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6684 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6685 This works around GCC bug 54561.
6687 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6689 More fixes for 'volatile' and setjmp/longjmp.
6690 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6691 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6692 (png_load_body) [HAVE_PNG]:
6693 (jpeg_load_body) [HAVE_JPEG]:
6694 New function, with most of the old parent function's body.
6695 (png_load) [HAVE_PNG]:
6696 (jpeg_load) [HAVE_JPEG]:
6697 Invoke the new function, to avoid longjmp munging our locals.
6698 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6699 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6700 longjmp is passed 2, as the C standard doesn't guarantee this.
6701 Instead, store the failure code into mgr->failure_code.
6703 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6705 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6706 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6707 (syms_of_keyboard): Remove support for unread-command-char.
6709 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6711 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6712 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6713 violation. (Bug#12426)
6715 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6717 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6719 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6721 * eval.c: Add `inhibit-debugger'.
6722 (Qinhibit_debugger): New symbol.
6723 (call_debugger): Bind it instead of Qdebug_on_error.
6724 (maybe_call_debugger): Test Vinhibit_debugger.
6725 (syms_of_eval): Define inhibit-debugger.
6726 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6727 (syms_of_xdisp): Remove inhibit-debug-on-message.
6729 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6731 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6732 If a nonvolatile local variable is written before a _longjmp to
6733 the frame containing the variable, and is read after the _longjmp,
6734 the value read is indeterminate. Some local variables of type
6735 'struct handler' and 'struct catchtag' are used in this way, so
6736 mark each of their slots as volatile if the slot can be set before
6737 _longjmp and read afterwards.
6738 * lisp.h (struct handler): var and chosen_clause are now volatile.
6739 (struct catchtag): val, next, and pdlcount are now volatile.
6741 * bidi.c (bidi_push_it, bidi_pop_it):
6742 * fns.c (copy_hash_table):
6743 * image.c (define_image_type):
6744 * keyboard.c (kbd_buffer_store_event_hold):
6745 * process.c (Fprocess_send_eof):
6746 * xfaces.c (x_create_gc) [HAVE_NS]:
6747 * xgselect.c (xg_select):
6748 Prefer assignment to memcpy when either will do.
6750 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6751 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6752 time an item is removed. No need to mark this function 'inline';
6753 the compiler knows better than we do.
6755 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6757 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6758 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6759 to change_frame_size (Bug#12388).
6760 (windowDidResize:): Pass YES to updateFrameSize.
6762 * nsterm.h: Add delay parameter to updateFrameSize.
6764 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6766 Discard killed buffers from deleted window and frame objects.
6767 This reduces an amount of references to killed buffers and
6768 helps GC to reclaim them faster.
6769 * alloc.c (discard_killed_buffers): New function.
6770 (mark_object): Use it for deleted windows and frames.
6771 (mark_object): If symbol's value is set up for a killed buffer
6772 or deleted frame, restore its global binding.
6773 * data.c (swap_in_global_binding): Add GC notice.
6774 (swap_in_symval_forwarding): Use convenient set_blv_where.
6775 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6776 * window.h: ... to here.
6778 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6780 Convenient macro to check whether the buffer is live.
6781 * buffer.h (BUFFER_LIVE_P): New macro.
6782 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6783 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6785 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6787 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6788 composition cases (Bug#12364).
6790 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6791 overhang of succeeding glyphs overlapping box cursor.
6793 * w32term.c (x_draw_glyph_string): Likewise.
6795 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6797 Simplify, document, and port floating-point (Bug#12381).
6798 The porting part of this patch fixes bugs on non-IEEE platforms
6799 with frexp, ldexp, logb.
6800 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6802 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6803 support, by removing commented-out code and briefly listing the
6804 C89 functions excluded. The commented-out stuff was confusing
6805 maintenance, e.g., we thought we needed cbrt but it was commented out.
6806 (logb): Remove decl; no longer needed.
6807 (isfinite): New macro, if not already supplied.
6808 (isnan): Don't replace any existing macro.
6809 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6810 are present on all C89 platforms.
6811 (Ffrexp): Do not special-case zero, as frexp does the right thing
6813 (Flogb): Do not use logb, as it doesn't have the desired meaning
6814 on hosts that use non-base-2 floating point. Instead, stick with
6815 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6816 frexp, to avoid getting an unspecified result.
6818 * xdisp.c (Qinhibit_debug_on_message): Now static.
6820 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6822 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6823 NSBezierPath (Bug#12131).
6825 2012-09-10 Chong Yidong <cyd@gnu.org>
6827 * fns.c (Fdelq, Fdelete): Doc fix.
6829 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6831 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6832 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6834 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6836 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6837 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6840 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6842 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6843 left fringe if the window has a left margin. This avoids leaving
6844 traces of the cursor because its leftmost pixel is not drawn over.
6846 * dispnew.c (update_window_line): When the left margin area of a
6847 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6848 that screen line. (Bug#12277)
6850 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6852 Assume C89 or later for math functions (Bug#12381).
6853 This simplifies the code, and makes it a bit smaller and faster,
6854 and (most important) makes it easier to clean up signal handling
6855 since we can stop worring about floating-point exceptions in
6856 library code. That was a problem before C89, but the problem
6857 went away many years ago on all practical Emacs targets.
6858 * data.c, image.c, lread.c, print.c:
6859 Don't include <math.h>; no longer needed.
6860 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6861 might be autoconfigured, as that never happens.
6863 * doprnt.c (DBL_MAX_10_EXP):
6864 * print.c (DBL_DIG):
6865 Remove. C89 or later always defines these.
6866 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6867 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6868 (arith_error, domain_error, domain_error2):
6869 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6870 no longer needed -- we simply return what C returns. All uses removed.
6871 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6873 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6874 Remove. All uses expanded, as these macros are no longer used
6875 more than once and are now more trouble than they're worth.
6876 (Ftan): Use tan, not sin / cos.
6877 (Flogb): Assume C89 frexp.
6878 (fmod_float): Assume C89 fmod.
6879 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6880 (init_floatfns): Remove. All uses removed.
6882 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6884 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6885 compositeToPoint for OSX < 10.6 (Bug#12390).
6887 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6889 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6890 This produces more-accurate results.
6892 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6894 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6895 changes (Bug#12088).
6897 2012-09-08 Chong Yidong <cyd@gnu.org>
6899 * syntax.c (Fstring_to_syntax): Doc fix.
6901 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6903 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6904 in the internal border.
6905 (x_set_window_size): Remove static variables and their usage.
6906 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6907 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6908 Remove fringe/internal border adjustment (Bug#11052).
6909 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6910 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6911 (ns_fix_rect_ibw): Remove.
6912 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6913 (ns_dumpglyphs_box_or_relief): Ditto.
6914 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6916 (ns_dumpglyphs_image): Ditto.
6917 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6919 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6920 their usage. Add fringe_extended_p and its use as in other terms.
6921 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6922 scroll bar was removed.
6923 (updateFrameSize): New function.
6924 (windowDidResize): Move code to updateFrameSize and call it.
6926 * nsterm.h (EmacsView): Add updateFrameSize.
6928 2012-09-07 Chong Yidong <cyd@gnu.org>
6930 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6932 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6934 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6936 More signal-handler cleanup (Bug#12327).
6937 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6938 Problem introduced when merging patches. Noted by Eli Zaretskii in
6939 <http://bugs.gnu.org/12327#67>.
6940 * floatfns.c: Comment fix.
6941 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6942 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6943 and anyway the declaration is harmless even if SIGDANGER is not defined.
6944 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6945 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6946 source files not surprisingly expected syssignal.h to define, or
6947 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6948 Include <sys/ioctl.h>, for FIONREAD.
6949 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6950 This eliminates a problem whereby other files mysteriously had
6951 to include "syssignal.h" before including "systty.h" if they
6952 wanted to use "#ifdef SIGIO".
6954 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6956 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6958 * w32.c (sigemptyset): Empty the set.
6959 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6961 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6963 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6965 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6966 (mark_object): Likewise for frame objects.
6968 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6970 * syssignal.h (handle_on_main_thread): Always declare,
6971 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6972 This ports to platforms without HAVE_PTHREAD.
6974 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6976 Signal-handler cleanup (Bug#12327).
6977 Emacs's signal handlers were written in the old 4.2BSD style with
6978 sigblock and sigmask and so forth, and this led to some
6979 inefficiencies and confusion. Rewrite these to use
6980 pthread_sigmask etc. without copying signal sets around. Also,
6981 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6982 'signal', and instead use functions that do not attempt to take
6983 over the system name space. This patch causes Emacs's text
6984 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6985 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6986 Do not include <signal.h> or "syssignal.h", as these
6987 modules do not use signals.
6988 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6989 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6990 Do not include <signal.h>, as "syssignal.h" does that for us now.
6991 * atimer.c (sigmask_atimers): New function.
6992 (block_atimers, unblock_atimers): New functions,
6993 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6995 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6996 no longer needed here.
6997 * emacs.c (main): Inspect existing signal handler with sigaction,
6998 so that there's no need to block and unblock SIGHUP.
6999 * sysdep.c (struct save_signal): New member 'action', replacing
7000 old member 'handler'.
7001 (save_signal_handlers, restore_signal_handlers):
7002 Use sigaction instead of 'signal' to save and restore.
7003 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
7004 New function. All users of 'signal' modified to use set_sighandler
7005 if they're writeonly, and to use sys_signal if they're read+write.
7006 (emacs_sigaction_init, forwarded_signal): New functions.
7007 (sys_signal): Remove. All uses replaced by calls to sigaction
7008 and emacs_sigaction_init, or by direct calls to 'signal'.
7009 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
7010 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
7011 all uses replaced by pthread_sigmask etc. calls.
7012 * syssignal.h: Include <signal.h>.
7013 (emacs_sigaction_init, forwarded_signal): New decls.
7014 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
7015 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
7016 (sigmask, sys_sigmask): Remove; no longer needed.
7017 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
7018 (sigblock, sigunblock, sigfree):
7019 (sigsetmask) [!defined sigsetmask]:
7020 Remove. All uses replaced by pthread_sigmask.
7021 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
7022 no longer need to be replaced, and its typical old uses
7023 are now done via emacs_sigaction_init and sigaction.
7024 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
7025 (sys_sigdel): Remove; unused.
7026 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
7028 2012-09-06 Eli Zaretskii <eliz@gnu.org>
7030 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
7031 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
7033 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7035 Explicitly mark buffer_defaults and buffer_local_symbols.
7036 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
7037 mark_local_symbols here.
7038 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
7039 since special buffers aren't marked here any more.
7040 (allocate_buffer): Chain new buffer with all_buffers here...
7041 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
7043 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
7044 (syms_of_buffer): Remove staticpro of the above.
7045 (init_buffer_once): Set names for buffer_defaults and
7046 buffer_local_symbols.
7048 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
7050 Use bool for booleans in font-related modules.
7051 * font.c (font_intern_prop, font_style_to_value)
7052 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
7053 (generate_otf_features, font_check_otf_features, font_check_otf)
7054 (font_match_p, font_list_entities, font_at):
7055 * fontset.c (fontset_id_valid_p, reorder_font_vector
7056 (fontset_find_font, Fset_fontset_font)
7057 (face_suitable_for_char_p) [0]:
7058 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
7059 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
7060 (m17n_flt_initialized, ftfont_shape_by_flt):
7061 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
7062 * nsfont.m (nsfont_draw):
7063 * w32font.c (w32font_draw):
7064 * w32term.c (x_draw_glyphless_glyph_string_foreground):
7065 Use bool for booleans.
7066 * font.h: Adjust to above API changes.
7067 (struct font, struct font_driver, struct font_driver_list):
7068 Use bool for booleans.
7069 (struct font): Remove useless member encoding_type.
7071 * fontset.c, xftfont.c: Omit unnecessary static decls.
7073 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
7075 * alloc.c (mark_object): Revert window marking code
7076 since it's unsafe for the Fset_window_configuration.
7078 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7080 Fix race conditions with signal handlers and errno (Bug#12327).
7081 Be more systematic about preserving errno whenever a signal
7082 handler returns, even if it's not in the main thread. Do this by
7083 renaming signal handlers to distinguish between signal delivery
7084 and signal handling. All uses changed.
7085 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
7086 * data.c (deliver_arith_signal): Rename from arith_error.
7087 * dispnew.c (deliver_window_change_signal): Rename from
7088 window_change_signal.
7089 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
7090 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
7091 * keyboard.c (deliver_input_available_signal): Rename from
7092 input_available_signal.
7093 (deliver_user_signal): Rename from handle_user_signal.
7094 (deliver_interrupt_signal): Rename from interrupt_signal.
7095 * process.c (deliver_pipe_signal): Rename from send_process_trap.
7096 (deliver_child_signal): Rename from sigchld_handler.
7097 * atimer.c (handle_alarm_signal):
7098 * data.c (handle_arith_signal):
7099 * dispnew.c (handle_window_change_signal):
7100 * emacs.c (handle_fatal_signal, handle_danger_signal):
7101 * keyboard.c (handle_input_available_signal):
7102 * keyboard.c (handle_user_signal, handle_interrupt_signal):
7103 * process.c (handle_pipe_signal, handle_child_signal):
7104 New functions, with the actual signal-handling code taken from the
7105 original respective signal handlers, sans the sporadic attempts to
7106 preserve errno, since that's now done by handle_on_main_thread.
7107 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
7108 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
7109 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7111 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7112 Move initialization of main_thread to sysdep.c's init_signals.
7113 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
7114 our usage, and simplifies the mainline code.
7115 (record_child_status_change): New static function, as a helper
7116 for handle_child_signal, and with most of the old child handler's
7118 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
7119 (handle_child_signal): Use the above.
7120 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
7121 Moved here from emacs.c.
7122 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
7123 code moved here from emacs.c's main function.
7124 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
7125 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
7126 This lets callers save and restore errno properly.
7128 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7130 Remove redundant or unused things here and there.
7131 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
7132 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
7133 * editfns.c (Fcompare_buffer_substrings): Likewise.
7134 * frame.h (struct terminal, struct font_driver_list):
7135 Remove redundant declarations.
7136 * window.h (Qleft, Qright): Likewise.
7138 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7140 Do not mark objects from deleted buffers, windows and frames.
7141 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
7142 (mark_object): Likewise for windows and frames.
7144 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
7146 * alloc.c (valid_lisp_object_p): Treat killed buffers,
7147 buffer_defaults and buffer_local_symbols as valid objects.
7148 Return special value to denote them.
7150 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
7152 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
7153 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
7154 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
7155 (file_name_absolute_p, Fsubstitute_in_file_name):
7156 (check_executable, check_writable, Ffile_accessible_directory_p)
7157 (Fset_file_selinux_context, Fdefault_file_modes)
7158 (Finsert_file_contents, choose_write_coding_system)
7159 (Fwrite_region, build_annotations, a_write, e_write)
7161 * filelock.c (boot_time_initialized, get_boot_time)
7162 (get_boot_time_1, lock_file_1, within_one_second):
7163 * floatfns.c (in_float):
7164 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
7165 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
7166 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
7167 * lisp.h (struct Lisp_Hash_Table.cmpfn):
7168 * window.c (compare_window_configurations):
7169 Use bool for booleans.
7170 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
7171 (Fdefault_file_modes): Now mode_t, not int, for modes.
7172 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
7173 (internal_delete_file): Now returns void, not a (boolean) int,
7174 since nobody was looking at the return value.
7175 * lisp.h, window.h: Adjust to above API changes.
7177 * xdisp.c (set_message): Simplify and reindent last change.
7179 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
7181 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
7183 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
7185 * eval.c (call_debugger): Make the function non-static so that we
7186 can call it from set_message.
7188 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
7189 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
7191 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7193 Give more-useful info on a fatal error (Bug#12328).
7194 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
7195 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
7196 of doing the work ourselves.
7197 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
7198 do most of the work.
7199 (fatal_error_backtrace): New function, taken from the guts
7200 of the old fatal_error_signal, but with a new option to output
7202 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
7203 info about the signal than just its number.
7204 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
7205 * sysdep.c: Include <execinfo.h>
7206 (emacs_backtrace): New function, taken partly from the previous
7207 code of the 'die' function.
7208 (emacs_abort): Call fatal_error_backtrace rather than abort.
7210 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
7212 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
7213 eager (load-time) macro-expansion.
7214 * lisp.mk (lisp): Add macroexp.
7216 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7218 Simplify redefinition of 'abort' (Bug#12316).
7219 Do not try to redefine the 'abort' function. Instead, redo
7220 the code so that it calls 'emacs_abort' rather than 'abort'.
7221 This removes the need for the NO_ABORT configure-time macro
7222 and makes it easier to change the abort code to do a backtrace.
7223 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
7224 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
7225 Remove; sysdep.c's emacs_abort now takes its place.
7226 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
7227 'abort' changed to use 'emacs_abort'.
7228 * msdos.c (dos_abort) [defined abort]: Remove; not used.
7229 (abort) [!defined abort]: Rename to ...
7230 (emacs_abort): ... new name.
7231 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
7232 the place of the old 'abort' in emacs.c.
7233 * w32.c, w32fns.c (abort): Do not #undef.
7234 * w32.c (emacs_abort): Rename from w32_abort.
7236 2012-09-04 Eli Zaretskii <eliz@gnu.org>
7238 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
7239 offsets[j].dv, since the y axis of the screen coordinates points
7240 down, while the y axis of the font definition coordinates points
7241 up. This fixes display of Arabic diacritics such as KASRA and
7242 KASRATAN. (Bug#11860)
7244 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
7246 Be more systematic about _setjmp vs setjmp.
7247 * alloc.c (test_setjmp, mark_stack):
7248 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
7249 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
7250 (png_load, my_error_exit, jpeg_load):
7251 * process.c (send_process_trap, send_process):
7252 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
7253 The underscored versions are up to 30x faster on some hosts.
7254 Formerly, the code used setjmp+longjmp sometimes and
7255 _setjmp+_longjmp at other times, with no particular reason to
7256 prefer setjmp+longjmp.
7258 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>
7260 Fix minor problem found by static checking.
7261 * buffer.c (Fdelete_all_overlays): Return nil.
7263 2012-09-03 Martin Rudalics <rudalics@gmx.at>
7265 * buffer.c (Fdelete_all_overlays): New function.
7267 2012-09-03 Chong Yidong <cyd@gnu.org>
7269 * gtkutil.c: Add extern decl for Qxft.
7271 2012-09-02 Paul Eggert <eggert@cs.ucla.edu>
7273 * emacs.c, eval.c: Use bool for boolean.
7274 * emacs.c (initialized, inhibit_window_system, running_asynch_code):
7275 (malloc_using_checking) [DOUG_LEA_MALLOC]:
7276 (display_arg) [HAVE_X_WINDOWS || HAVE_NS]:
7277 (noninteractive, no_site_lisp, fatal_error_in_progress, argmatch)
7278 (main, decode_env_path, Fdaemon_initialized):
7279 * eval.c (call_debugger, Finteractive_p, interactive_p):
7280 (unwind_to_catch, Fsignal, wants_debugger, skip_debugger)
7281 (maybe_call_debugger, Fbacktrace):
7282 * process.c (read_process_output, exec_sentinel):
7283 Use bool for booleans.
7284 * emacs.c (shut_down_emacs): Omit unused boolean argument NO_X.
7285 All callers changed.
7286 * eval.c (interactive_p): Omit always-true boolean argument
7287 EXCLUDE_SUBRS_P. All callers changed.
7288 * dispextern.h, lisp.h: Reflect above API changes.
7289 * firstfile.c (dummy): Use the address of 'main', whose signature
7290 won't change, instead of the address of 'initialize', whose
7291 signature just changed from int to bool.
7292 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
7293 * msdos.c (fatal_error_in_progress): ... from here.
7294 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
7296 (redisplay_internal, unwind_redisplay): Simply clear
7297 REDISPLAYING_P when unwinding, instead of saving its previous,
7298 always-false value and then restoring it.
7300 Clean up some extern decls.
7301 Mostly, this hoists extern decls out of .c files and into .h files.
7302 That way, we're more likely to catch errors if the interfaces change.
7303 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not

7752 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7753 are all boolean, so make them single-bit bitfields.
7755 * lisp.h (ASET): Remove attempt to detect side effects.
7756 It was meant to be temporary and it often doesn't work,
7757 because when IDX has side effects the behavior of IDX==IDX
7758 is undefined. See Stefan Monnier in
7759 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7761 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7763 * lisp.h (functionp): New function (extracted from Ffunctionp).
7764 (FUNCTIONP): Use it.
7765 * eval.c (Ffunctionp): Use it.
7767 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7769 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7770 as that's faster and simpler than static storage. Don't bother
7771 with the g_main_context_query overhead if g_main_context_pending
7772 says no events are pending.
7773 (gfds, gfds_size): Remove these static vars.
7774 (xgselect_initialize): Remove; no longer needed.
7775 All uses and decls removed.
7777 * emacs.c (fatal_error_signal_hook): Remove.
7778 All uses removed. This leftover from old code was always 0.
7780 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7781 * casefiddle.c (casify_object, casify_region):
7782 * casetab.c (set_case_table):
7783 * category.c, category.h (word_boundary_p):
7784 * category.h (CHAR_HAS_CATEGORY):
7785 Use bool for booleans, instead of int.
7787 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7789 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7791 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7793 On assertion failure, print backtrace if available.
7794 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7795 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7796 * Makefile.in (LIB_EXECINFO): New macro.
7799 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7800 * bytecode.c (exec_byte_code):
7801 * callint.c (check_mark, Fcall_interactively):
7802 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7803 (getenv_internal, sync_process_alive, call_process_exited):
7804 * lisp.h (USE_SAFE_ALLOCA):
7805 Use bool for booleans, instead of int.
7806 * lisp.h, process.h: Adjust prototypes to match above changes.
7807 * callint.c (Fcall_interactively): Don't assume the mark's
7808 offset fits in 'int'.
7810 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7812 * buffer.c, buffer.h: Use bool for boolean.
7813 * buffer.c (reset_buffer_local_variables)
7814 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7815 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7816 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7817 (overlay_touches_p, overlay_strings, Foverlay_put)
7818 (report_overlay_modification, call_overlay_mod_hooks):
7819 (mmap_enlarge, mmap_set_vars):
7820 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7821 Use bool for booleans, instead of int.
7822 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7823 since the 1-or-0 return value is always ignored anyway.
7824 (mmap_initialized_p):
7825 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7826 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7828 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7830 * bidi.c: Use bool for boolean.
7831 This is a bit more readable, and makes the text segment of bidi.o
7832 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7833 Presumably it's faster too.
7834 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7836 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7837 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7838 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7839 (bidi_explicit_dir_char, bidi_level_of_next_char)
7840 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7841 Use bool for booleans, instead of int.
7842 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7843 (bidi_unshelve_cache): Adjust decls to match code.
7845 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7847 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7850 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7852 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7853 * atimer.h: Include <stdbool.h>.
7855 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7857 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7858 compile time tests instead of run time tests on systems that do
7860 (FRAME_MAC_P): Remove leftover from deleted code.
7861 * frame.c (syms_of_frame): Remove leftover from deleted code.
7863 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7865 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7867 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7869 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7870 Otherwise, the compiler complains about (A?B:C) where B is void
7871 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7872 (fontset_add): Return void, for FONTSET_ADD.
7874 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7876 * alloc.c: Use bool for booleans.
7877 (gc_in_progress, abort_on_gc)
7878 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7879 (dont_register_blocks) [GC_MALLOC_CHECK]:
7880 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7881 (check_string_bytes, make_specified_string, memory_full)
7882 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7883 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7884 (mark_stack, valid_pointer_p, make_pure_string)
7885 (Fgarbage_collect, survives_gc_p, gc_sweep):
7886 Use bool for booleans, instead of int.
7887 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7888 Remove unused local.
7889 * alloc.c (PURE_POINTER_P):
7890 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7891 * editfns.c (Fformat):
7892 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7894 * fns.c (sweep_weak_table):
7895 * lisp.h (suppress_checking, push_message, survives_gc_p)
7896 (make_pure_string, gc_in_progress, abort_on_gc):
7897 * lread.c (readchar, read1):
7898 * print.c (Fprin1_to_string):
7899 * xdisp.c (push_message):
7900 Use bool for booleans affected directly or indirectly by
7903 Make recently-introduced setters macros.
7904 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7905 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7906 (set_fontset_default, set_fontset_fallback): Rename from their
7907 upper-case counterparts, and make them functions rather than macros.
7908 This is more consistent with the other recently-introduced setters.
7909 These don't need to be inline, since they're local.
7911 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7913 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7914 the loop (Bug#12247).
7916 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7918 * lisp.h (vcopy): Use memcpy rather than our own loop.
7919 This fixes a performance regression introduced by the recent
7920 addition of vcopy. This means 'vcopy' will need to be modified
7921 for a copying collector, but that's OK. Also, tighten the
7922 checking in the assertion.
7924 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7926 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7927 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7928 non-base glyph for the width of the base character, according to
7929 what x_draw_composite_glyph_string_foreground expects.
7930 Generate WADJUST value according to composition_gstring_width's
7931 expectations, to produce correct width of the composed character.
7932 Reverse the sign of the DU offset produced by ScriptPlace.
7934 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7936 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7938 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7940 Avoid direct writes to contents member of struct Lisp_Vector.
7941 * lisp.h (vcopy): New function to copy data into vector.
7942 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7943 * fns.c (Ffillarray): Use ASET.
7944 * keyboard.c (timer_check_2): Use AREF and ASET.
7945 (append_tool_bar_item, Frecent_keys): Use vcopy.
7946 * lread.c (read_vector): Use ASET.
7947 * msdos.c (Frecent_doskeys): Use vcopy.
7948 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7949 (Finternal_merge_in_global_face): Use ASET and vcopy.
7950 * xfont.c (xfont_list_pattern): Likewise.
7952 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7954 * window.c (Fwindow_point): For the selected window always return
7955 the position of its buffer's point.
7956 (Fset_window_point): For the selected window always go in its
7957 buffer to the specified position.
7959 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7961 Setter macros for fontsets.
7962 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7963 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7964 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7967 2012-08-20 Glenn Morris <rgm@gnu.org>
7969 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7970 Don't assume that `ln -f' works.
7972 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7974 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7975 and later about non-assignments with no effect. See discussion at
7976 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7979 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7981 Inline setter functions for Lisp_Objects slots of struct specbinding.
7982 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7985 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7987 * window.c (select_window): Always make selected window's buffer
7990 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7992 Use AREF and ASET for docstrings of category tables.
7993 * category.h (CATEGORY_DOCSTRING): Use AREF.
7994 (SET_CATEGORY_DOCSTRING): Use ASET.
7995 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7997 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7999 Inline setter functions for hash table members.
8000 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
8001 (set_hash_hash, set_hash_index): Rename with _slot suffix.
8002 (set_hash_key_and_value, set_hash_index, set_hash_next)
8003 (set_hash_hash): New functions.
8004 * charset.c, fns.c: Adjust users.
8006 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
8008 Inline getter and setter functions for per-buffer values.
8009 * buffer.h (per_buffer_default, set_per_buffer_default)
8010 (per_buffer_value, set_per_buffer_value): New functions.
8011 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
8012 * buffer.c, data.c: Adjust users.
8014 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
8016 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
8018 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
8020 Rely on <config.h> + <unistd.h> to declare 'environ',
8021 as gnulib does this if the system doesn't.
8022 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
8023 Remove declaration. MS-Windows declares it on stdlib.h which is
8024 included by conf_post.h.
8025 * emacs.c (environ) [DOUG_LEA_MALLOC]:
8026 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
8027 * vm-limit.c: Include <unistd.h>, for 'environ'.
8029 * unexaix.c, unexcoff.c: Include "mem-limits.h".
8030 (start_of_data): Remove decl; mem-limits.h provides it.
8032 * xdisp.c (handle_invisible_prop): Make it a bit faster
8033 and avoid a gcc -Wmaybe-uninitialized diagnostic.
8035 2012-08-19 Chong Yidong <cyd@gnu.org>
8037 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
8040 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
8042 * .gdbinit: Use call instead of set when calling a function in the
8045 * data.c (set_internal): Don't use set_blv_found.
8046 (Fkill_local_variable): Likewise.
8048 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
8050 * nsfont.m (ns_ascii_average_width): Ensure the string
8051 ascii_printable is initialized with a null-terminated character
8052 array. Otherwise, it can contain undesired extra characters.
8054 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8056 port new setting code to Sun C 5.8 2005/10/13
8057 * chartab.c, lisp.h (char_table_set, char_table_set_range):
8058 Return void, not Lisp_Object. Otherwise, the compiler
8059 complains about (A?B:C) where B is void and C is Lisp_Object
8060 when compiling CHAR_TABLE_SET, due to the recent change to
8061 the API of sub_char_table_set_contents.
8063 2012-08-18 Chong Yidong <cyd@gnu.org>
8065 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
8066 for the string case (Bug#3874).
8068 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
8070 * buffer.h (BSET): Remove (Bug#12215).

8147 * terminal.c (TERMHOOKS_INLINE):

8149 are compiled into code.
8150 (tset_param_alist): New setter function.
8152 2012-08-17 Paul Eggert <eggert@cs.ucla.edu>
8154 * keyboard.h (KSET): Remove (Bug#12215).

8894 * w32.c (init_environment): Change the default values of many
8895 environment variables in dflt_envvars[] to NULL, to avoid pushing
8896 them into environment when they were not already defined.
8897 Remove the code that deletes site-lisp subdirectories from the default
8898 value of EMACSLOADPATH, as it is no longer needed.
8899 (check_windows_init_file): Now external, not static.
8900 Use Vload_path as is, without adding anything, as this function is now
8901 called when Vload_path is already set up.
8903 * w32.h (check_windows_init_file): Add prototype.
8905 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

8949 Remove unnecessary pointer casts.
8950 * alloc.c (record_xmalloc): New function.
8951 * lisp.h (record_xmalloc): New decl.
8952 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
8953 more like a function. This is because the pointer cast is not
8954 needed. All uses changed.
8955 * print.c (print_string, print_error_message): Avoid length recalc.
8957 Improve fix for macroexp crash with debugging (Bug#12118).
8958 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
8959 ARRAY_MARK_FLAG when checking subscripts, because ASET is
8960 not supposed to be invoked from the garbage collector.

8962 (gc_aset): New function, which is like ASET but can be
8963 used in the garbage collector.

8992 with addition of handling of symlinks and support for 'lstat'.
8993 If possible, get file's attributes and security information by
8994 handle, not by name. Produce S_IFLNK bit for symlinks, when
8995 called from 'lstat'.
8996 (stat, lstat): New functions, call 'stat_worker'.
8997 (symlink, readlink, careadlinkat): Rewritten to create and resolve
8998 symlinks when the underlying filesystem supports them.
9000 2012-08-02 Paul Eggert <eggert@cs.ucla.edu>
9002 Fix macroexp crash on Windows with debugging (Bug#12118).
9003 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
9004 checking subscripts; problem introduced with the recent
9005 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
9006 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
9007 since it's used in non-static inline functions now.
9009 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
9010 Don't assume buffer size fits in 'int'. Remove unused local.

9030 * composite.c (COMPOSITE_INLINE):
9031 * dispnew.c (DISPEXTERN_INLINE):
9032 * sysdep.c (SYSTIME_INLINE):
9033 Define to EXTERN_INLINE, so that the corresponding functions
9034 are compiled into code.
9035 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
9036 (INLINE_HEADER_END): New macros.
9037 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

9057 hard-coding the path separator.
9059 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
9061 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
9062 This how ASET and AREF are supposed to work, and makes
9063 it easier to think about future improvements. See

9524 * charset.c (define_charset_internal): Likewise.
9525 * coding.c (syms_of_coding): Likewise.
9526 * keymap.c (syms_of_keymap): Likewise.
9527 * search.c (syms_of_search): Likewise.

9532 * xfns.c (syms_of_xfns): Likewise.
9534 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9536 Fast save_excursion_save and save_excursion_restore.
9537 * lisp.h (struct Lisp_Excursion): New data type.
9538 (PVEC_EXCURSION): New pseudovector type.
9539 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9540 to deal with it. Adjust comments.

9554 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9555 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9556 emacs.c, as this is a more-suitable home. Had this been done earlier
9557 the fix for 12036 would have avoided some of the problems noted in
9558 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9559 would have been more obvious.
9560 * emacs.c: Do not include <verify.h>; no longer needed.
9561 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9562 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9563 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9564 Remove; now done in lisp.h.
9565 * lisp.h (PUBLISH_TO_GDB): New macro.

9567 (DATA_SEG_BITS): Use it.
9568 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9569 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9570 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9571 not be usable in #if. This simplifies things.
9573 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9575 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9577 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

9580 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9581 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9582 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9583 Adjust to changes in lisp.h and emacs.c, by using
9584 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9585 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9586 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9587 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9588 instead of gdb_valbits.
9589 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9590 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9591 instead of gdb_array_mark_flag.
9592 (xboolvector): Get size from $->size, not $->header.size.
9593 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9594 (xreload, hook-run, hookpost-run): Remove.
9595 * emacs.c: Include <verify.h>.
9596 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9597 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9599 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9600 (gdb_USE_LSB_TAG): New enum constants.
9601 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9602 Also define these as enum constants, so they're visible to GDB.
9603 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9604 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9605 as constants, so they're visible to GDB.
9606 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9607 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9608 Now enum constants, not macros, so they're visible to GDB.
9609 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9610 more convenient now. All uses changed.
9611 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9612 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9614 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9621 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9622 add argument, tune behavior, and adjust all callers.
9624 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9626 Use typedef for EMACS_INT, EMACS_UINT.
9627 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9628 than macros. This simplifies debugging in the usual case, since
9629 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9630 and it allows expressions involving EMACS_INT casts.
9631 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9633 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

9643 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9645 Adjust buffer text indirection counters at the end of Fkill_buffer.
9646 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9647 buffer is definitely dead. This should really fix an issue reported
9648 by Christoph Scholtes again. (Bug#12007).
9649 (init_buffer_once): Initialize indirection counters of
9650 buffer_defaults and buffer_local_symbols (for sanity and safety).
9652 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9654 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9655 and continuation glyphs on tooltip frames, leave them at zero.
9656 Avoids continued lines in tooltips. (Bug#11832)
9658 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>

9667 or invalid. (Bug#12025)
9669 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
9670 it signals an error when a tooltip frame is being created.
9672 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9674 Cleanup miscellaneous objects allocation and initialization.

9683 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9685 Swap buffer text indirection counters in Fbuffer_swap_text.
9686 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9687 This avoids crash reported by Christoph Scholtes at
9688 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9690 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9692 * nsmenu.m (Popdown_data): New struct.
9693 (pop_down_menu): p->pointer is Popdown_data. Release the pool and

9715 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9717 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9718 as it's limited by the amount of memory, not by INT_MAX.
9720 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9722 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9723 in special-event-map. See the discussion at

9804 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
9805 'for_each_per_buffer_object_at'.
9806 All uses changed. It's better to use upper-case for macros that

9869 padding before the data member of a bool vector.
9870 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
9871 than doing the check by hand with an abort ().
9873 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9875 * eval.c (Fdefvar): Don't check constants since we only set the var if
9876 it's not yet defined anyway (bug#11904).
9878 * lisp.h (last_undo_boundary): Declare new var.
9879 * keyboard.c (command_loop_1): Set it.
9880 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
9881 were auto-added by the command loop (bug#11774).
9883 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>

10389 Move GNU_LIBRARY_PENDING_OUTPUT_COUNT to configure.
10391 2012-07-11 John Wiegley <johnw@newartisans.com>
10393 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
10394 function attribute, so we only use it if it exists in the
10397 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10399 Avoid call to strlen in fast_c_string_match_ignore_case.
10400 * search.c (fast_c_string_match_ignore_case): Change to use
10401 length argument. Adjust users accordingly.
10402 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
10404 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>
10406 Assume mkdir, rmdir.

10408 * sysdep.c (rmdir) [!HAVE_RMDIR]: Remove.
10411 * sysdep.c (rename) [!HAVE_RENAME]: Remove.
10414 * s/hpux10-20.h (HAVE_PERROR): Remove.
10415 * sysdep.c (perror) [HPUX && !HAVE_PERROR]:
10416 Remove dummy definition, as this problem was obsolete long ago.
10419 * sysdep.c (strerror) [!HAVE_STRERROR && !WINDOWSNT]: Remove.
10421 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10423 Avoid calls to strlen in font processing functions.
10424 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
10425 (font_open_by_name): Change to use length argument.
10426 Adjust users accordingly.
10427 * font.h (font_open_by_name, font_parse_xlfd, font_unparse_xlfd):
10429 * xfont.c (xfont_decode_coding_xlfd, font_unparse_xlfd):
10430 Change to return ptrdiff_t.
10431 (xfont_list_pattern, xfont_match): Use length returned by
10432 xfont_decode_coding_xlfd.

10438 Move DONT_REOPEN_PTY to configure.
10440 * sound.c (DEFAULT_SOUND_DEVICE) [!WINDOWSNT]:
10441 * s/netbsd.h (DEFAULT_SOUND_DEVICE): Let configure set it.
10443 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
10445 Remove "#define unix" that is no longer needed (Bug#11905).
10446 * s/aix4-2.h (unix): Remove; no longer needed.
10448 EMACS_TIME simplification (Bug#11875).
10449 This replaces macros (which typically do not work in GDB)
10450 with functions, typedefs and enums, making the code easier to debug.
10451 The functional style also makes code easier to read and maintain.
10452 * systime.h: Include <sys/time.h> on all hosts, not just if
10453 WINDOWSNT, since 'struct timeval' is needed in general.
10454 (EMACS_TIME): Now a typedef, not a macro.
10455 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
10457 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
10458 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

10462 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
10463 which are not functions. All uses rewritten to use:
10464 (make_emacs_time): New function.
10465 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
10466 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
10467 not functions. All uses rewritten to use the following, respectively:
10468 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
10469 (add_emacs_time, sub_emacs_time): New functions.
10470 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
10471 * fileio.c (Fcopy_file):
10472 * xterm.c (XTflash): Get the current time closer to when it's used.
10473 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
10475 * bytecode.c (targets): Suppress -Woverride-init warnings.
10477 Simplify by avoiding confusing use of strncpy etc.
10478 * doc.c (Fsnarf_documentation):
10479 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
10480 * frame.c (Fmake_terminal_frame):
10481 * gtkutil.c (get_utf8_string):
10483 * nsmenu.m (ns_update_menubar):
10484 * regex.c (regerror):
10485 Prefer memcpy to strncpy and strncat when either will do.
10486 * fileio.c (Fsubstitute_in_file_name):
10487 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
10488 (menu_separator_name_p):
10489 * nsmenu.m (ns_update_menubar):
10490 Prefer memcmp to strncmp when either will do.
10491 * nsterm.m: Include <ftoastr.h>.
10493 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10494 Prefer snprintf to strncpy.
10495 * nsterm.m (ns_term_init):
10496 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10497 * nsterm.m (ns_term_init):
10498 Avoid the need for strncpy, by using build_string or
10499 make_unibyte_string directly. Use dtoastr, not snprintf.
10500 * process.c (Fmake_network_process): Diagnose service names that
10501 are too long, rather than silently truncating them or creating
10502 non-null-terminated names.
10503 (Fnetwork_interface_info): Likewise, for interface names.
10504 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10505 Prefer sprintf to strncat.
10506 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10507 Prefer vsnprintf to vsprintf + strncpy.
10509 2012-07-10 Glenn Morris <rgm@gnu.org>
10511 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
10512 Clarify fallback case.
10514 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10516 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10517 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10518 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10519 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10520 where argument type is known to be a Lisp_Cons.
10522 2012-07-10 Tom Tromey <tromey@redhat.com>
10524 * bytecode.c (BYTE_CODE_THREADED): New macro.
10525 (BYTE_CODES): New macro. Replaces all old byte-code defines.
10526 (enum byte_code_op): New type.
10527 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
10528 (exec_byte_code): Use them. Use token threading when applicable.
10530 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10532 Optimize pure C strings initialization.
10533 * lisp.h (make_pure_string): Fix prototype.
10534 (build_pure_c_string): New function, defined as static inline. This
10535 provides a better opportunity to optimize away calls to strlen when
10536 the function is called with compile-time constant argument.
10537 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10538 argument, adjust users accordingly. Use build_pure_c_string where
10540 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10541 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10542 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10544 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10546 Avoid calls to strlen in miscellaneous functions.
10547 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10548 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10549 * lread.c (openp): Likewise.
10551 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10553 Avoid calls to strlen in path processing functions.
10554 * fileio.c (file_name_as_directory): Add comment. Change to add
10555 srclen argument and return the length of result. Adjust users
10557 (directory_file_name): Fix comment. Change to add srclen argument,
10558 swap 1st and 2nd arguments to obey the common convention.
10559 Adjust users accordingly.
10560 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10562 2012-07-10 Glenn Morris <rgm@gnu.org>
10564 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
10565 Move PENDING_OUTPUT_COUNT definition to configure.
10567 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10568 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10569 * s/gnu.h (DATA_START): Move definitions to configure.
10571 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10572 We include usg5-4-common.h, which defines them both.
10574 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10575 O_RDONLY already includes it).
10577 Stop ns builds setting the EMACSLOADPATH environment variable.
10578 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10579 Now it does not set EMACSLOADPATH, just returns the load-path string.
10580 * nsterm.h: Update accordingly.
10581 * lread.c [HAVE_NS]: Include nsterm.h.
10582 (init_lread) [HAVE_NS]: Use ns_load_path.
10583 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10585 2012-07-09 Glenn Morris <rgm@gnu.org>
10587 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10588 since the included bsd-common.h does so.
10590 Stop ns builds setting the EMACSPATH environment variable.
10591 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10592 (ns_init_paths): Do not set EMACSPATH.
10593 * nsterm.h (ns_exec_path): Add it.
10594 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10597 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10599 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10601 * process.c (wait_reading_process_output): 'waitchannels' was unset
10602 when read_kbd || !NILP (wait_for_cell); fix this.
10604 Add GCC-style 'const' attribute to functions that can use it.
10605 * character.h (char_resolve_modifier_mask):
10606 * keyboard.h (make_ctrl_char):
10607 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10608 (init_character_once, next_almost_prime, init_fns, init_image)
10609 (flush_pending_output, init_sound):
10610 * mem-limits.h (start_of_data):
10611 * menu.h (finish_menu_items):
10612 Add ATTRIBUTE_CONST.
10613 * emacs.c (DEFINE_DUMMY_FUNCTION):
10614 Declare the dummy function with ATTRIBUTE_CONST.
10615 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
10616 Add decls with ATTRIBUTE_CONST.
10618 Minor improvements to make_formatted_string.
10619 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10620 where int is good enough, as vsprintf returns an int.
10621 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10623 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10625 Use make_formatted_string to avoid double length calculation.
10626 * lisp.h (make_formatted_string): New prototype.
10627 * alloc.c (make_formatted_string): New function.
10628 * buffer.c (Fgenerate_new_buffer_name): Use it.

10634 * image.c (gs_load): Likewise.
10635 * minibuf.c (get_minibuffer): Likewise.
10636 * msdos.c (dos_set_window_size): Likewise.
10637 * process.c (make_process): Likewise.
10638 * xdisp.c (ensure_echo_area_buffers): Likewise.
10639 * xsettings.c (apply_xft_settings): Likewise.
10641 2012-07-09 Glenn Morris <rgm@gnu.org>
10643 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10644 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10645 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.

10648 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10650 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10652 Move marker debugging code under MARKER_DEBUG.
10653 * marker.c (MARKER_DEBUG): Move marker debugging code under
10654 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10655 for bootstrap with --enable-checking (~3x slowdown reported
10656 by Juanma Barranquero <lekktu@gmail.com>).
10657 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10659 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10661 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10662 See <http://bugs.gnu.org/11825#29>.
10664 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10666 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10667 has no font, use the frame's font. (Bug#11813)
10668 (display_line): Add commentary about displaying truncation glyphs
10670 (produce_special_glyphs): Move here from term.c.
10672 * term.c (produce_special_glyphs): Move to xdisp.c.
10674 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10677 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10679 * xdisp.c (display_line): Avoid warning about implicit declaration
10682 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10684 * lisp.h: Remove empty conditional.
10686 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10688 * lread.c (load_path_check): Now static.
10690 Fix some minor --with-ns problems found by static checking.
10691 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10692 (x_set_font) [!HAVE_X_WINDOWS]:
10693 * image.c (xpm_load_image) [HAVE_NS]:
10694 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10695 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10696 Remove unused local.
10697 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10698 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10699 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10700 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10701 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10702 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10703 Fix pointer signedness problem.
10704 * xfaces.c (FRAME_X_FONT_TABLE):
10705 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10707 2012-07-07 Glenn Morris <rgm@gnu.org>
10709 * lread.c (load_path_check): New function, split from init_lread.
10710 (init_lread): Reorganize. Motivation:
10711 If EMACSLOADPATH is set, check/warn about that rather than the
10712 defaults, which we are not going to use. Hence we can remove
10713 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10714 Don't warn if site-lisp directories are missing.
10715 If not installed, start from a blank load-path, since
10716 PATH_LOADSEARCH refers to the eventual installation directories.
10718 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10720 Support truncation and continuation glyphs on GUI frames, when
10721 fringes are disabled. (Bug#11832)
10722 * xdisp.c (init_iterator): Get dimensions of truncation and
10723 continuation glyphs even if on GUI frames.
10724 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10725 or both, are absent.
10726 (start_display, move_it_in_display_line_to): Handle the case of a
10727 GUI frame without a fringe to display continuation or truncation
10729 (insert_left_trunc_glyphs): Support GUI frames: make sure
10730 truncation glyphs overwrite enough glyphs from the current line to
10731 have sufficient space in pixels.
10732 (display_line): Support truncation and continuation glyphs on GUI
10733 frames. If some spare pixels are left on the line after inserting
10734 the truncation glyphs, fill that space with a stretch glyph of a
10735 suitably computed width.
10737 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10738 produce_glyphs, to support GUI sessions.
10740 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10742 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10744 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10746 Do not require float-time's arg to fit in time_t (Bug#11825).
10747 This works better on hosts where time_t is unsigned, and where
10748 float-time is applied to the (negative) difference between two times.
10749 * editfns.c (decode_time_components): Last arg is now double *,
10750 not int *, and means to store all the result as a double, without
10751 worrying about whether the seconds part fits in time_t.
10752 All callers changed.
10753 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10754 All callers changed.
10755 (Ffloat_time): Do not fail merely because the specified time falls
10756 outside of time_t range.
10758 2012-07-07 Glenn Morris <rgm@gnu.org>
10760 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
10761 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
10762 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
10764 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
10766 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
10767 Update dependencies.
10769 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
10771 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10773 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
10774 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
10775 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
10776 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
10777 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
10778 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
10780 * xfont.c (compare_font_names): Redo to omit the need for casts.
10782 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
10784 * xfns.c (Fx_change_window_property): Doc fix.
10785 * w32fns.c (Fx_change_window_property): Doc fix.
10787 * w32fns.c (Fx_window_property): Accept the same arguments as the
10788 X Windows version. Doc fix.
10789 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
10791 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10792 Eli Zaretskii <eliz@gnu.org>
10794 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
10795 Windows-specific code from nt/config.nt moved here.
10796 Obsolete settings removed.
10798 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10800 * process.c: Avoid unnecessary calls to gettime.
10801 (wait_reading_process_output): Don't get the time of day
10802 when gobbling data immediately and not waiting, as there's no need
10803 for it in that case. This removes a FIXME.
10805 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10807 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10808 is defined (Bug#11768).
10810 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10812 Fix marker debugging code.
10813 * marker.c (byte_char_debug_check): Do not perform the check
10814 if buffer is not multibyte.
10815 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10816 Call byte_char_debug_check with correct arguments.
10818 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10820 Compile marker debugging code only if ENABLE_CHECKING is defined.
10821 * marker.c (byte_char_debug_check, count_markers):
10822 Use only if ENABLE_CHECKING is defined.
10823 (byte_debug_flag): Remove.
10824 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10825 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

10834 Consistently rename charno to charpos.
10835 (marker_position): Add eassert.
10836 (marker_byte_position): Convert to eassert.
10838 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

10855 * window.c (save_window_save): Likewise.
10857 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10859 Do not use Fdelete_overlay in delete_all_overlays
10860 to avoid redundant calls to unchain_overlay.
10861 * buffer.c (drop_overlay): New function.
10862 (delete_all_overlays, Fdelete_overlay): Use it.
10863 * minibuf.c (get_minibuffer): Fix comment.
10865 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10867 Port to OpenBSD 5.1 amd64.
10868 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10869 This is needed for OpenBSD, and should be harmless on all BSD systems.
10870 Also, include <sys/sysctl.h>, as it should be available on all
10871 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10872 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10873 use p_pid member, not kp_proc.pid.
10875 2012-07-06 Glenn Morris <rgm@gnu.org>
10877 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10879 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10881 More xmalloc and related cleanup.

10890 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10892 Omit needless casts involving void * pointers and allocation.
10893 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10894 as the former is more robust if P's type is changed.
10895 Prefer xzalloc to xmalloc + memset 0.
10896 Simplify malloc-or-realloc to realloc.
10897 Don't worry about xmalloc returning a null pointer.
10898 Prefer xstrdup to xmalloc + strcpy.
10899 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
10901 * keyboard.c (apply_modifiers_uncached): Prefer local array to
10902 alloca of a constant.
10904 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10906 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10907 hscroll is larger than the line width. Fixes long and futile
10908 looping inside extend_face_to_end_of_line (on a TTY) producing
10909 glyphs that are not needed and thrown away.
10911 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10913 * marker.c (set_marker_restricted_both): Simplify by using
10916 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10918 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10922 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
10923 not defined (Bug#11768).
10924 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
10925 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
10926 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
10927 followed by gtk_box_set_homogeneous (Bug#11768).
10928 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10929 (update_theme_scrollbar_width, xg_create_scroll_bar):
10930 Use gtk_scrollbar_new (Bug#11768).
10931 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
10932 (is_box_type): New function (Bug#11768).
10933 (xg_tool_item_stale_p): Call is_box_type.
10934 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10935 with default display (Bug#11768).
10937 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10939 * xdisp.c (window_hscroll_limited): New function.
10940 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10941 coordinates when window's hscroll is set to insanely large
10942 values. (Bug#11857)
10944 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

11005 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
11007 * fileio.c (time_error_value): Check the right error number.
11008 Problem reported by Troels Nielsen in
11009 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
11011 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11013 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
11014 This should be fixed in a better way; see Eli Zaretskii in
11015 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
11016 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
11018 * fileio.c (time_error_value): Rename from special_mtime.
11019 The old name's problems were noted by Eli Zaretskii in
11020 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
11022 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
11023 This variable's comment says Emacs needs at least one GDB-visible
11024 symbol of type enum pvec_type, to work around GDB problems.
11025 The symbol's value doesn't matter.
11027 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
11028 that causes compilation to fail on pre-C99 compilers.
11030 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
11032 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
11033 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
11035 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11037 * buffer.c (init_buffer_once): Fix initialization of
11038 headers for buffer_defaults and buffer_local_symbols.
11039 Reported by Juanma Barranquero <lekktu@gmail.com>.

11046 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
11047 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
11048 change in pvec_type.
11049 (PSEUDOVECTOR_TYPEP): New macro.
11050 (TYPED_PSEUDOVECTORP): Use it.
11051 * fns.c (internal_equal): Adapt code to extract pvectype.
11052 * emacs.c (gdb_pvec_type): Update type.
11053 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
11054 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
11055 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
11056 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
11057 (sweep_vectors): Use it. Use local var `total_bytes' instead of
11058 abusing vector->header.next.nbytes.
11059 (live_vector_p): Use PVEC_TYPE.
11060 (mark_object): Adapt code to extract pvectype. Use switch.
11062 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11064 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
11065 Tighten new eassert a bit.
11067 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11069 Fix compilation with --enable-gcc-warnings and -O1
11070 optimization level.
11071 * doprnt.c (doprnt): Change type of tem to int, initialize
11072 to avoid compiler warning. Add eassert.
11073 * search.c (simple_search): Initialize match_byte to avoid
11074 compiler warning. Add eassert.
11076 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11078 Avoid weird behavior with large horizontal scrolls.
11079 Without this change, for example, large hscroll values would
11080 mess up Emacs's display on Fedora 15 x86, presumably due to
11081 overflows in int calculations in the display code.
11082 Also, if buffers had long lines, Emacs would freeze.
11083 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
11084 (set_window_hscroll): New function, containing the old guts of
11085 Fset_window_hscroll. Return the clipped value.
11086 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
11087 This avoids the need to check against PTRDIFF_MAX.
11089 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
11091 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
11093 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
11095 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
11097 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
11098 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
11099 since GCC 4.4.6 issues a bogus warning for them.
11101 Fix bugs in file timestamp newness comparisons.
11102 * fileio.c (Ffile_newer_than_file_p):
11103 * lread.c (Fload): Use full timestamp resolution of files,
11104 not just the 1-second resolution, so that files that are only
11105 slightly newer still count as newer.
11106 * fileio.c (Ffile_newer_than_file_p): Don't assume file
11107 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
11109 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
11111 * fileio.c: Improve handling of file time marker. (Bug#11852)
11112 (special_mtime): New function.
11113 (Finsert_file_contents, Fverify_visited_file_modtime):
11114 Use it to set special mtime values consistently.
11116 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
11118 * fileio.c (Finsert_file_contents): Properly handle st_mtime
11119 marker for non-existing file. (Bug#11852)
11121 2012-07-03 Glenn Morris <rgm@gnu.org>
11123 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
11124 and did not make it into globals.h).
11126 2012-07-03 Tom Tromey <tromey@redhat.com>
11128 * window.c (Fset_window_margins, Fset_window_fringes)

11172 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
11173 values which aren't power of 2.
11174 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
11175 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users
11178 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
11180 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
11182 * alloc.c (mark_object): Revert part of last patch to use `switch'.
11184 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11186 * alloc.c (allocate_vector_block): Remove redundant
11187 calls to mallopt if DOUG_LEA_MALLOC is defined.
11188 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
11189 avoid calls to mallopt if zero_vector is returned.
11191 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11193 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
11194 is enabled, avoid dereferencing NULL current_sblock if
11197 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
11199 Cleanup basic buffer management.
11200 * buffer.h (struct buffer): Change layout to use generic vector
11201 marking code. Fix some comments. Change type of 'clip_changed'
11202 to bitfield. Remove unused #ifndef old.
11203 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
11204 (GET_OVERLAYS_AT): Fix indentation.

11210 struct buffer. Fix comment.
11211 (mark_overlay): New function.
11212 (mark_buffer): Use it. Use mark_vectorlike to mark normal
11213 Lisp area of struct buffer.
11214 (mark_object): Use it. Adjust marking of misc objects
11215 and related comments.
11217 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
11219 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
11220 wrapper that is not needed because the wrapped code is a no-op (zero
11221 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
11222 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
11224 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
11226 * alloc.c (mark_buffer): Simplify. Remove prototype.
11227 (mark_object): Add comment. Reorganize marking of vector-like
11228 objects. Use CHECK_LIVE for all vector-like objects except buffers
11229 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
11230 Avoid redundant calls to mark_vectorlike for bool vectors.
11232 2012-06-30 Glenn Morris <rgm@gnu.org>
11234 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
11236 * epaths.in (PATH_SITELOADSEARCH): New.
11237 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
11238 This is rather than relying on --enable-locallisppath elements
11239 having "site-lisp" in their names. (Bug#10208#25, 11658)
11241 2012-06-30 Eli Zaretskii <eliz@gnu.org>
11243 * w32proc.c (sys_select): Accept and ignore one more argument.
11245 * w32.c (emacs_gnutls_pull): Call select with one more argument.

11250 * sysdep.c: Don't include dos.h and dosfns.h.
11252 * process.c (sys_select):
11253 * msdos.c (sys_select): Accept one more argument and ignore it.
11255 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
11256 adapt data types and code to that.
11259 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
11260 which clashes with the gnulib function of the same name.
11262 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
11264 * font.c (font_style_to_value, font_style_symbolic)
11265 (font_prop_validate_style): Add type checks for values in
11268 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
11270 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
11273 2012-06-29 Eli Zaretskii <eliz@gnu.org>
11275 * xdisp.c (try_window_id): Undo last change.
11277 * w32.c (getwd): Adjust commentary about startup_dir.
11278 (init_environment): Always call sys_access, even in non-MSVC
11279 builds. Don't chdir to the directory of the Emacs executable.
11280 This undoes code from 1997 which was justified by the need to
11281 "avoid conflicts when removing and renaming directories". But its
11282 downside was that every relative file name was being interpreted
11283 relative to the directory of the Emacs executable, which can never
11284 be TRT. In particular, it broke sys_access when called with
11285 relative file names.
11286 (sys_access): Map GetLastError to errno.
11288 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

11330 * window.h (struct window): Change type of 'hscroll',
11331 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
11332 'last_modified' and 'last_overlay_modified' to EMACS_INT.
11333 Adjust users accordingly.
11334 * xdisp.c (try_cursor_movement): Replace type check with eassert.
11335 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
11336 from EMACS_INT to ptrdiff_t.

11439 when building with Clang.

11470 * alloc.c: Remove build_string.

11478 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11480 Use sprintf return value instead of invoking strlen on result.
11481 In the old days this wasn't portable, since some sprintf
11482 implementations returned char *. But they died out years ago and
11483 Emacs already assumes sprintf returns int.
11484 Similarly for float_to_string.
11485 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11492 * xfns.c (syms_of_xfns):
11493 Use sprintf or float_to_string result to avoid need to call strlen.
11494 * data.c (Fnumber_to_string):
11495 Use make_unibyte_string, since the string must be ASCII.
11496 * lisp.h, print.c (float_to_string): Now returns int length.
11497 * term.c (produce_glyphless_glyph):
11498 Use sprintf result rather than recomputing it.
11500 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

11507 * dispextern.h (xstrcasecmp): Define to library function
11508 strcasecmp if available.

11527 sprintf already null-terminates its output.
11529 * xfns.c (x_window): Remove redundant cast.
11531 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11533 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11534 `const char *' to `char *' to avoid compiler warning.
11536 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11538 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11539 instead of truncating it to 63 (admittedly a generous limit).
11541 * process.c: Fix spelling and caps in comments.
11543 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

11599 * keyboard.c (kbd_buffer_get_event):
11600 * process.c (Faccept_process_output):
11601 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11602 This improves on the previous patch, which introduced a bug
11603 when time_t is unsigned and as wide as intmax_t.
11604 See <http://bugs.gnu.org/9000#51>.
11606 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11635 language ID in the event parameters.
11637 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11638 event.code, not the obscure "character set ID".
11640 2012-06-23 Chong Yidong <cyd@gnu.org>

11671 Support higher-resolution time stamps (Bug#9000).
11672 The time stamps are only nanosecond-resolution at the C level,
11673 since that's the best that any real-world system supports now.
11674 But they are picosecond-resolution at the Lisp level, as that's
11675 easy, and leaves room for future OS improvements.
11677 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
11680 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
11681 Don't get current time unless it's needed.
11683 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
11684 now provides it if it's absent.
11685 (start_atimer): Port to higher-res time stamps.
11686 Check for time stamp overflow. Don't get current time more
11687 often than is needed.
11689 * buffer.h (struct buffer): Buffer modtime now has high resolution.
11690 Include systime.h, not time.h.

11694 (Ffile-attributes): File times now have higher resolution.
11696 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
11697 (struct image): Timestamp now has higher resolution.
11699 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
11700 has at least microseconds now. All uses removed.
11701 (update_frame, update_single_window, update_window, update_frame_1)
11702 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
11703 (duration_to_sec_usec): Remove; no longer needed.

11711 (decode_time_components, lisp_seconds_argument): New functions.
11712 (make_time): Now static.
11713 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
11714 Report an error if the time is invalid, rather than having the caller
11717 * fileio.c: Include <stat-time.h>
11718 (Fcopy_file): Copy higher-resolution time stamps.
11719 Prefer to set the time stamp via a file descriptor if that works.
11720 (Fset_file_times, Finsert_file_contents, Fwrite_region)
11721 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
11722 (Fvisited_file_modtime, Fset_visited_file_modtime):
11723 Support higher-resolution time stamps.
11725 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
11727 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
11729 * image.c (prepare_image_for_display, clear_image_cache)
11730 (lookup_image): Port to higer-resolution time stamps.
11732 * keyboard.c (start_polling, bind_polling_period):
11733 Check for time stamp overflow.

11736 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
11737 Port to higher-resolution time stamps. Do not assume time_t is signed.
11738 (decode_timer): New function. Timers are now vectors of length 9,
11739 not 8, to accommodate the picosecond component.
11740 (timer_check_2): Use it.
11742 * nsterm.m (select_timeout, timeval_subtract): Remove.
11743 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
11744 as they're a bit more accurate and handle overflow better.
11745 (ns_select): Change prototype to be compatible with pselect.
11746 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11747 * nsterm.h (ns_select): Adjust prototype.
11749 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
11750 us-resolution time stamps.
11751 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
11753 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
11755 * lisp.h (time_overflow): New decl.

11759 * process.h (struct Lisp_Process.read_output_delay):
11760 Now counts nanoseconds, not microseconds.
11761 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
11763 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
11764 (wait_reading_process_output):
11765 Port to ns-resolution time stamps.
11766 (Faccept_process_output, wait_reading_process_output):
11767 Check for time stamp overflow. Do not assume time_t is signed.
11768 (select_wrapper): Remove; we now use pselect.
11769 (Fprocess_attributes): Now generates ns-resolution time stamps.
11771 * sysdep.c: Include utimens.h. Don't include utime.h
11772 or worry about struct utimbuf; gnulib does that for us now.
11773 (gettimeofday): Remove; gnulib provides a substitute.
11774 (make_timeval): New function.
11775 (set_file_times): Now sets ns-resolution time stamps.
11776 New arg FD; all uses changed.
11777 (time_from_jiffies, ltime_from_jiffies, get_up_time)
11778 (system_process_attributes):
11779 Now returns ns-resolution time stamp. All uses changed.
11780 Check for time stamp overflow.
11782 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
11783 provides a substitute now.
11785 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11786 since it guarantees struct timespec.
11787 (EMACS_TIME): Now struct timespec, so that we can support
11788 ns-resolution time stamps.
11789 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11790 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11791 (EMACS_USECS): Remove.
11792 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11793 so multiply the arg by 1000 before storing it.
11794 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11796 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

11803 (make_timeval, make_lisp_time, decode_time_components): New decls.
11804 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
11805 that it mishandled time_t overflow. You can't compare by subtracting!
11806 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11807 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
11809 * term.c: Include <sys/time.h>.
11810 (timeval_to_Time): New function, for proper overflow wraparound.
11811 (term_mouse_position, term_mouse_click): Use it.
11813 * undo.c (record_first_change): Support higher-resolution time stamps
11814 in the undo buffer.
11815 (Fprimitive_undo): Use them when restoring time stamps.
11817 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
11818 (w32_get_internal_run_time):
11819 Port to higher-resolution Emacs time stamps.
11820 (ltime): Now accepts single 64-bit integer, as that's more convenient
11823 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
11825 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11826 for compatibility with pselect. Support ns-resolution time stamps.
11828 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
11830 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11831 Check for time stamp overflow, and support ns-resolution time stamps.
11833 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
11834 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
11835 (timeval_subtract): Remove; no longer needed.
11836 (XTflash, XTring_bell, x_wait_for_event):
11837 Port to ns-resolution time stamps. Don't assume time_t is signed.
11839 2012-06-22 Chong Yidong <cyd@gnu.org>

11843 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11845 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11846 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11847 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11848 staticidx goes up to 1597 out of 1600 = 0x640.)
11850 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11852 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
11853 Otherwise, the umask might be mistakenly 0 while handling input signals.
11855 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
11857 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

11863 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
11864 access to `contents' member of Lisp_Vector objects with AREF and ASET
11867 2012-06-19 Chong Yidong <cyd@gnu.org>
11869 * frame.c (delete_frame): When selecting a frame on a different
11870 text terminal, do not alter the terminal's top-frame.
11872 * xdisp.c (format_mode_line_unwind_data): Record the target
11873 frame's selected window and its terminal's top-frame.
11874 (unwind_format_mode_line): Restore them.
11875 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
11877 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
11878 since tty frames can be explicitly named.
11879 (prepare_menu_bars): Likewise.
11881 * term.c (Ftty_top_frame): New function.
11883 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11885 Port byte-code-meter to modern targets.
11886 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
11887 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
11888 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
11889 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
11890 (METER_1, METER_2): Simplify.
11892 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
11894 * data.c (Fdefalias): Return `symbol' (bug#11686).
11896 2012-06-18 Martin Rudalics <rudalics@gmx.at>
11898 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11899 gets killed during executing of this function (Bug#11665).
11900 Try to always return Qt when the buffer has been actually killed.
11901 (Vkill_buffer_query_functions): In doc-string say that functions
11902 run by this hook should not change the current buffer.
11904 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
11906 Fix recently-introduced process.c problems found by static checking.

11924 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
11926 * lisp.h (eassert): Assume C89 or later.
11927 This removes the need for CHECK.
11928 (CHECK): Remove. Its comments about always evaluating its
11929 argument were confusing, as 'eassert' typically does not evaluate
11932 * coding.c (produce_chars): Use ptrdiff_t, not int.
11934 * xterm.c (x_draw_underwave): Check for integer overflow.
11935 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

12121 as the union type is for debugging, not for production.
12122 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
12123 Use an inline function on all platforms when using the union type,
12124 since this is simpler and 'static inline' can be used portably

12241 adjust comment accordingly.
12242 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
12243 to denote vector blocks. Adjust users (live_vector_p,

12266 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
12268 * doprnt.c (doprnt): Truncate multibyte char correctly.
12269 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
12270 would mishandle a string argument "Xc" if X was a multibyte
12271 character of length 2: it would truncate after X's first byte
12272 rather than including all of X.
12274 2012-06-06 Chong Yidong <cyd@gnu.org>
12276 * buffer.c (word_wrap): Doc fix.

12323 * minibuf.c (Fassoc_string): Remove duplicate declaration.
12325 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
12326 Convert pctcpu and pctmem to Lisp float properly.
12327 Let the compiler fold better, as 100.0/0x8000 is exact.
12329 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
12331 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
12334 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

12338 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
12340 For a 'struct window', replace some Lisp_Object fields to
12341 bitfields where appropriate, remove unused fields.
12342 * window.h (struct window): Remove unused 'last_mark_x' and
12343 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
12344 change its type from Lisp_Object to bitfield.
12345 Change type of 'force_start', 'optional_new_start',
12346 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
12347 fields from Lisp_Object to bitfield. Adjust users accordingly.
12349 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12351 Pacify gcc -Wdouble-precision when using Xaw.
12352 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
12353 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
12354 Use 'float' consistently, rather than 'float' in most places
12355 and 'double' in a couple of places.
12357 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12359 * xdisp.c (handle_stop): Detect whether we have overlay strings
12360 loaded by testing it->current.overlay_string_index to be
12361 non-negative, instead of checking whether n_overlay_strings is
12362 positive. (Bug#11587)
12364 2012-05-31 Chong Yidong <cyd@gnu.org>
12366 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

12370 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12372 * search.c (search_buffer): Remove calls to
12373 r_alloc_inhibit_buffer_relocation, as it is now called by
12374 maybe_unify_char, which was the cause of relocation of buffer text
12377 2012-05-31 Eli Zaretskii <eliz@gnu.org>
12379 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
12380 for the duration of call to load_charset, to avoid problems with
12381 callers of maybe_unify_char that access buffer text through C
12384 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
12385 decrement the inhibition flag, instead of just setting or
12388 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
12390 Remove obsolete '#define static' cruft.
12391 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
12392 This #undef was "temporary" in 2000; it is no longer needed
12393 now that '#define static' has gone away.
12394 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
12395 (gray_bitmap_bits): Remove; no longer needed.
12396 All uses replaced with definiens.

12402 The following changes affect the code only when profiling.
12403 * dispnew.c (__executable_start): Rename from safe_bcopy.
12404 Define only on platforms that need it.
12405 * emacs.c: Include <sys/gmon.h> when profiling.
12406 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12407 (__executable_start): Remove decl, since lisp.h does it now.
12408 (safe_bcopy): Remove decl; no longer has that name.
12409 (main): Coalesce #if into single bit of code, for simplicity.
12410 Cast pointers to uintptr_t, since standard libraries want integers
12412 * lisp.h (__executable_start): New decl.
12414 2012-05-31 Glenn Morris <rgm@gnu.org>
12416 * image.c (Fimagemagick_types): Doc fix.

12439 Do not create empty overlays with the evaporate property (Bug#9642).
12440 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12441 Bug#9642, but explicitly check that the buffer the overlay would
12442 be moved to is live and rearrange lines to make sure that errors
12443 will not put the overlay in an inconsistent state.
12444 (Fdelete_overlay): Cosmetics.
12446 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12448 * w32term.c (my_bring_window_to_top): New function.
12449 (x_raise_frame): Use handle returned by DeferWindowPos, which
12450 could be different from the original one.

12464 to not catch an out-of-range value.
12466 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12468 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

12482 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12483 Only r_alloc_inhibit_buffer_relocation needed to be added;
12484 the others were already declared.
12486 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12487 before checking whether it's out of range. Put the check inside
12489 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12491 2012-05-27 Ken Brown <kbrown@cornell.edu>

12503 they are now on lisp.h.
12505 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12507 * search.c (search_buffer): Use it to inhibit relocation of buffer
12508 text while re_search_2 is doing its job, because re_search_2 is
12509 passed C pointers to buffer text. (Bug#11519)
12511 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12512 Update value to 24.
12514 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12515 state after an additional call to move_it_in_display_line_to, keep
12516 the values of it->max_ascent and it->max_descent found for the
12518 (pos_visible_p): Revert the comparison against bottom_y to what it
12519 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12522 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12524 Fix coding-related core dumps with gcc -ftrapv.
12525 The code was computing A - B, where A and B are pointers, and B is
12526 random garbage. This can lead to core dumps on platforms that
12527 have special pointer registers, and it also leads to core dumps on
12528 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12529 A - B only when B is initialized properly.
12530 * coding.c (coding_set_source, coding_set_destination): Return void.
12531 (coding_change_source, coding_change_destinations): New functions,
12532 with the old behaviors of coding_set_source and coding_set_destination.

12546 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12548 (initialize_w32_display): Initialize mouse-highlight data.
12550 * w32inevt.c: Include termchar.h and window.h.
12551 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12552 moves, call note_mouse_highlight. If help_echo changed, call
12553 gen_help_event to produce help-echo message in the echo area.
12554 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12557 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12559 * lread.c (read1): Simplify slightly to avoid an overflow warning
12560 with GCC 4.7.0 on x86-64.
12562 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12564 * bidi.c (bidi_mirror_char): Revert last change: an int is
12565 definitely wide enough here.

12577 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
12579 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12581 Use int, not EMACS_INT, where int is wide enough.
12582 (inhibit_garbage_collection, Fgarbage_collect):

12603 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12607 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12608 (report_overlay_modification):

12610 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12611 Omit pointer cast, which isn't needed anyway, and doesn't work
12612 after the EMACS_INT -> ptrdiff_t change.
12613 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12614 * buffer.h: Adjust decls to match defn changes elsewhere.
12615 (struct buffer_text, struct buffer):
12616 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

12618 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
12619 not int, to avoid needless 32-bit limit on 64-bit hosts.
12620 (exec_byte_code): Use tighter memory-full test, one that checks
12621 for alloca overflow. Don't compute the address of the object just
12622 before an array, as that's not portable. Use EMACS_INT, not
12623 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12624 * callint.c (Fcall_interactively):
12625 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12626 * callproc.c (call_process_kill, Fcall_process):
12627 Don't assume pid_t fits into an Emacs fixnum.

12638 (casify_object): Avoid integer overflow when overallocating buffer.
12639 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

12642 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12643 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

12647 For CCL_MapSingle, check that content and value are in int range.
12648 (ccl_driver, Fregister_code_conversion_map):
12649 Check that Vcode_version_map_vector is a vector.
12650 (resolve_symbol_ccl_program): Check that vector header is in range.
12651 Always copy the vector, so that we can check its contents reliably
12652 now rather than having to recheck each instruction as it's being
12653 executed. Check that vector words fit in 'int'.
12654 (ccl_get_compiled_code, Fregister_ccl_program)
12655 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12656 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

12658 contents are in range.
12659 (Fccl_execute_on_string): Check that status is in range.
12660 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12661 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12662 Accept and return EMACS_INT, not int, because callers can pass values

12681 (Fdefine_charset_internal): Check ranges here, more carefully.
12682 Don't rely on undefined behavior with signed left shift overflow.
12683 Don't assume unsigned int fits into fixnum, or that fixnum fits
12684 into unsigned int. Don't require max_code to be a valid fixnum;
12685 that's not true for gb10830 4-byte on a 32-bit host. Allow
12686 invalid_code to be a cons, for the same reason. Require code_offset
12687 to be a character. Avoid int overflow if max_char is close
12689 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12690 this is intended anyway and avoids some undefined behavior.
12691 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12692 INDEX_TO_CODE_POINT, as that's what it expects.
12693 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12694 * charset.h (DECODE_CHAR): Return int, not unsigned;
12695 this is what was intended anyway, and it avoids undefined behavior.

12697 integer-overflow issues.
12698 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12699 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12700 where the argument is EMACS_INT, and this behavior is not intended.
12701 * chartab.c (Fmake_char_table, Fset_char_table_range)
12702 (uniprop_get_decoder, uniprop_get_encoder):
12703 Don't assume fixnum fits in int.
12704 * cmds.c (move_point): New function, that does the gist of
12705 Fforward_char and Fbackward_char, but does so while checking
12706 for integer overflow more accurately.
12707 (Fforward_char, Fbackward_char): Use it.
12708 (Fforward_line, Fend_of_line, internal_self_insert)
12709 (internal_self_insert):
12710 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13357 * xterm.c (x_x_to_emacs_modifiers):
13358 Don't assume EMACS_INT overflows nicely into int.
13359 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
13360 may come from Lisp.
13361 (handle_one_xevent): NATNUMP can eval its arg twice.
13362 (x_connection_closed):

13369 2012-05-25 Glenn Morris <rgm@gnu.org>
13371 * lisp.mk (lisp): Update for more files being compiled now.
13373 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
13375 * lread.c: Remove `read_pure' which makes no difference.
13376 (read_pure): Remove var.
13377 (unreadpure): Remove function.
13378 (readevalloop): Don't call read_list with -1 flag.
13379 (read1, read_vector): Don't test read_pure any more.
13380 (read_list): Simplify.
13382 * fileio.c, character.h: Minor style tweaks.

13388 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
13390 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
13391 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
13393 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
13396 This directory predates autoconf and is no longer needed nowadays.
13397 Move its few remaining bits of functionality to where they're needed.
13398 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
13399 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
13400 * m/template.h: Remove.
13401 * Makefile.in (M_FILE): Remove. All uses removed.
13402 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
13403 * lisp.h (USE_LSB_TAG):
13404 * mem-limits.h (EXCEEDS_LISP_PTR):
13405 Use VAL_MAX, not VALBITS, in #if.
13406 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
13407 (EMACS_UINT): Define unconditionally now.
13408 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
13409 (BITS_PER_EMACS_INT): New constants, replacing
13410 what used to be in config.h, but not useful in #if.
13411 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
13412 define them any more.
13413 (VAL_MAX): New macro.
13415 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
13416 BITS_PER_EMACS_INT, in #if.
13417 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
13418 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
13419 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
13420 * s/ms-w32.h (DATA_START):
13421 Move here from removed file m/intel386.h.
13422 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
13423 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
13425 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
13427 Assume C89 or later.
13428 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
13429 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
13431 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

13437 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
13438 * xterm.c (input_signal_count): Assume volatile works.
13440 2012-05-21 Ken Brown <kbrown@cornell.edu>
13442 * xgselect.c (xg_select): Fix first argument in call to 'select'
13445 2012-05-20 Ken Brown <kbrown@cornell.edu>
13447 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
13448 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
13450 2012-05-19 Ken Brown <kbrown@cornell.edu>
13452 * xfns.c (x_in_use): Remove `static' qualifier.
13453 * xterm.h (x_in_use): Declare.
13454 * xgselect.c: Include xterm.h.
13455 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
13456 and `display_arg' (bug#9754).
13458 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
13460 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
13462 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
13463 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
13465 2012-05-18 Eli Zaretskii <eliz@gnu.org>
13467 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
13469 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
13470 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
13472 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
13473 reference to image_cache->refcount.
13474 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
13476 2012-05-17 Juri Linkov <juri@jurta.org>
13478 * search.c (Fword_search_regexp, Fword_search_backward)
13479 (Fword_search_forward, Fword_search_backward_lax)
13480 (Fword_search_forward_lax): Move functions to isearch.el
13481 (bug#10145, bug#11381).
13483 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13485 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13487 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13489 * lread.c (init_obarray): Declare Qt and Qnil as special.
13491 2012-05-14 Glenn Morris <rgm@gnu.org>
13493 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13494 Put "libexec" before "bin", for the sake of init_callproc_1.
13496 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13498 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
13500 * unexaix.c: Port to more-recent AIX compilers.
13501 (report_error, report_error_1, make_hdr, copy_sym)
13502 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13503 Make arguments const char *, not char *, to avoid violations of C
13504 standard and to fix some AIX warnings reported by Gilles Pion.
13506 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13508 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13509 already have overlays loaded.
13510 (handle_single_display_spec): Before returning without displaying
13511 fringe bitmap, synchronize the bidi iterator with the main display
13512 iterator, by calling iterate_out_of_display_property.
13513 (iterate_out_of_display_property): Detect buffer iteration by
13514 testing that it->string is a Lisp string.
13515 (get_next_display_element): When the current object is exhausted,
13516 and there's something on it->stack, call set_iterator_to_next to
13517 proceed with what's on the stack, instead of returning zero.
13518 (set_iterator_to_next): If called at the end of a Lisp string,
13519 proceed to consider_string_end without incrementing string
13520 position. Don't increment display vector index past the end of
13521 the display vector. (Bug#11417)
13522 (pos_visible_p): Don't report a position visible when move_it_to
13523 stopped at the last line of window, which happens to be scanned
13524 backwards by the bidi iteration. (Bug#11464)
13526 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13528 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13529 and right-margin display specs even if the spec is invalid or we
13530 are on a TTY, and thus unable to display on the fringes.
13531 That's because the text with the property will not be displayed anyway,
13532 so we need to signal to the caller that this is a "replacing"
13533 display spec. This fixes display when the spec is invalid or we
13536 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13538 * unexaix.c (make_hdr): Fix typo in prototype.
13539 This bug broke the build on AIX. Problem reported by Gilles Pion.
13541 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13543 * keyboard.c (kbd_buffer_get_event): Read special events also in
13544 batch mode. (Bug#11415)
13546 2012-05-12 Glenn Morris <rgm@gnu.org>
13548 * ns.mk: Update for ns_appbindir no longer having trailing "/".
13550 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13552 * lisp.mk (lisp): Add newcomment.elc.
13554 2012-05-12 Glenn Morris <rgm@gnu.org>
13556 * Makefile.in (MKDIR_P): New, set by configure.
13557 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13559 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13561 Remove unused function hourglass_started.
13562 * dispextern.h (hourglass_started):
13563 * w32fns.c (hourglass_started):
13564 * xdisp.c (hourglass_started): Remove.
13566 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
13568 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13569 Update dependencies.
13571 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13573 * xgselect.c (xg_select): Put maxfds+1 into a var.
13574 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13576 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13578 2012-05-10 Dave Abrahams <dave@boostpro.com>
13580 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13581 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13583 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13585 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13586 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13587 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13588 Initialize xd_registered_buses.
13590 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13592 Untag more efficiently if USE_LSB_TAG.
13593 This is based on a proposal by YAMAMOTO Mitsuharu in
13594 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13595 For an admittedly artificial (nth 8000 longlist) benchmark on
13596 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13597 Emacs's overall text size by 1%.
13598 * lisp.h (XUNTAG): New macro.
13599 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13600 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13601 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13602 * eval.c (Fautoload):
13603 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13604 * frame.h (XFRAME): Use XUNTAG.
13606 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13607 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13608 Remove unportable assumptions about print widths of types like
13610 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13611 intptr_t when converting between pointer and integer, to avoid GCC
13612 warnings about wrong width.
13614 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13616 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13617 stack for each reader_thread, instead of defaulting to 8MB
13618 determined by the linker. This avoids failures in creating
13619 subprocesses on Windows 7, see the discussion in this thread:
13620 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13622 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13624 Fix up display of the *Minibuf-0* buffer in the mini window.
13625 * keyboard.c (read_char): Don't clear the echo area if there's no
13627 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13628 contents of *Minibuf-0*) if there's no message displayed in its stead.
13630 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13632 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13635 2012-05-06 Chong Yidong <cyd@gnu.org>
13637 * lisp.mk (lisp): Update.
13639 2012-05-05 Jim Meyering <meyering@redhat.com>
13641 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13643 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13645 * data.c (PUT_ERROR): New macro.
13646 (syms_of_data): Use it. Add new error type `user-error'.
13647 * undo.c (user_error): New function.
13648 (Fprimitive_undo): Use it.
13649 * print.c (print_error_message): Adjust print style for `user-error'.
13650 * keyboard.c (user_error): New function.
13651 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13653 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13655 Do not limit current-time-string to years 1000..9999.
13656 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13657 (Fcurrent_time_string): Support any year that is supported by the
13658 underlying localtime representation. Don't use asctime, as it
13659 has undefined behavior for years outside the range -999..9999.
13661 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13663 Fix race conditions involving setenv, gmtime, localtime, asctime.
13664 Without this fix, interrupts could mess up code that uses these
13665 nonreentrant functions, since setting TZ invalidates existing
13666 tm_zone or tzname values, and since most of these functions return
13667 pointers to static storage.
13668 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13669 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13670 Grow the critical sections to include not just invoking
13671 localtime/gmtime, but also accessing these functions' results
13672 including their tm_zone values if any, and any related TZ setting.
13673 (format_time_string): Last arg is now struct tm *, not struct tm **,
13674 so that the struct tm is saved in the critical section.
13675 All callers changed. Simplify allocation of initial buffer, partly
13676 motivated by the fact that memory allocation needs to be outside
13677 the critical section.
13679 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13681 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13682 with RESET_INTERVAL.
13684 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13685 Remove duplicated buffer name initialization.
13687 2012-05-02 Jim Meyering <jim@meyering.net>
13689 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13691 * xfns.c (x_window): Use xstrdup (Bug#11375).
13693 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13695 * xdisp.c (pos_visible_p): If already at a newline from the
13696 display string before the 'while' loop, don't walk back the glyphs
13697 from it3.glyph_row. Solves assertion violation when the display

13708 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13709 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13710 All were removed before 23.1.
13712 * dispnew.c: Remove HAVE_LIBNCURSES test;
13713 it is always true on relevant platforms.
13715 * Makefile.in (LD_SWITCH_X_SITE_RPATH):

13728 Do not avoid creating empty evaporating overlays (Bug#9642).
13729 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13730 That is, do not delete an evaporating overlay if it becomes
13731 empty after its bounds are adjusted to fit within its buffer.
13732 This fix caused other problems, and I'm reverting it until we get
13733 to the bottom of them.
13735 2012-04-27 Chong Yidong <cyd@gnu.org>
13737 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13739 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13741 * xdisp.c (pos_visible_p): If the window start position is beyond
13742 ZV, start the display from buffer beginning. Prevents assertion
13743 violation in init_iterator when the minibuffer window is scrolled
13744 via the scroll bar.
13746 * window.c (window_scroll_pixel_based): Likewise.
13748 2012-04-27 Chong Yidong <cyd@gnu.org>

13755 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13757 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13759 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13760 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13762 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13764 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13765 display element, check also the underlying string or buffer
13766 character. (Bug#11341)
13768 * w32menu.c: Include w32heap.h.
13769 (add_menu_item): If the call to AppendMenuW (via
13770 unicode_append_menu) fails, disable Unicode menus only if we are
13771 running on Windows 9X/Me.
13773 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13775 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13776 (xgetint): Add missing shift for LSB tags.
13778 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13780 * keyboard.c (read_char): Don't wipe echo area for select window

13786 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13787 manipulation of :loaded-from data.
13789 2012-04-23 Juanma Barranquero <lekktu@gmail.com>

13792 now a cons (bug#11311).
13794 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13796 Do not create empty overlays with the evaporate property (Bug#9642).
13797 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13798 if it becomes empty after its bounds are adjusted to fit within
13799 its buffer. Without this fix, in a nonempty buffer (let ((o
13800 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13801 yields an empty overlay that has the evaporate property, which is
13802 not supposed to happen.

13825 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13826 (__malloc_size_t, __malloc_ptrdiff_t):
13827 Remove. All uses removed, replaced by the definiens if needed,

13917 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
13919 * sysdep.c [__FreeBSD__]: Minor cleanups.
13920 (list_system_processes, system_process_attributes) [__FreeBSD__]:
13921 Use Emacs indenting style more consistently. Avoid some casts.

13933 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>
13935 * keyboard.c (process_pending_signals): Define only if SYNC_INPUT.
13936 It is never used otherwise.
13938 2012-04-20 Stefan Monnier <monnier@iro.umontreal.ca>
13940 * print.c (print_preprocess): Only check print_depth if print-circle
13942 (print_object): Check for cycles even when print-circle is nil and

14007 (NEED_MEM_INSERT): New macro.
14008 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.

14137 2012-04-09 Eli Zaretskii <eliz@gnu.org>
14139 * xdisp.c (set_cursor_from_row): If the display string appears in
14140 the buffer at position that is closer to point than the position
14141 after the display string, display the cursor on the first glyph of
14142 the display string. Fixes cursor display when a 'display' text
14143 property immediately follows invisible text. (Bug#11094)
14145 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
14147 composite.c: use 'double' consistently
14148 * composite.c (get_composition_id): Use 'double' consistently
14149 instead of converting 'float' to 'double' and vice versa; this is
14150 easier to understand and avoids a GCC warning.
14152 2012-04-09 Glenn Morris <rgm@gnu.org>
14154 * Makefile.in: Generate leim-list with bootstrap-emacs, in
14155 preparation for dumping it with emacs. (Bug#4789)
14156 (leimdir): New variable.
14157 ($(leimdir)/leim-list.el): New rule.
14158 (emacs$(EXEEXT)): Depend on leim-list.el.

14176 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
14177 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
14178 (mark_memory): Mark Lisp_Objects only if pointers might hide in
14179 objects, as mark_maybe_pointer will catch them otherwise.
14180 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
14181 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
14183 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
14185 Fix typo that broke non-Windows builds.

14188 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14190 Support building on MS-Windows with libxml2.
14192 * makefile.w32-in (OBJ2): Add xml.$(O).

14199 [!WINDOWSNT]: New macros.
14200 (init_libxml2_functions, libxml2_loaded_p): New functions.
14201 (parse_region): Call fn_xmlCheckVersion instead of using the macro
14202 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
14203 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
14204 Calls xmlCleanupParser only if libxml2 was loaded (or statically
14206 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
14207 Call init_libxml2_functions before calling libxml2 functions.
14208 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
14210 * emacs.c: Don't include libxml/parser.h.
14211 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
14212 xmlCleanupParser directly.
14214 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
14216 2012-04-07 Eli Zaretskii <eliz@gnu.org>
14218 * indent.c (Fvertical_motion): If there is a display string at
14219 point, use it.vpos to compute how many lines to backtrack after
14220 move_it_to point. (Bug#11133)
14222 2012-04-06 Eli Zaretskii <eliz@gnu.org>
14224 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
14225 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
14226 about subtle differences between FETCH_CHAR* and STRING_CHAR*
14227 macros related to unification of CJK characters. For the details,
14228 see the discussion following the message here:
14229 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
14231 2012-04-04 Chong Yidong <cyd@gnu.org>
14233 * keyboard.c (Vdelayed_warnings_list): Doc fix.
14235 2012-04-01 Eli Zaretskii <eliz@gnu.org>
14237 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
14238 instead of alloca. (Bug#11138)
14240 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
14242 * w32menu.c (is_simple_dialog): Properly check lisp types.
14245 2012-03-31 Eli Zaretskii <eliz@gnu.org>
14247 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
14248 position we get to after a call to move_it_to fails the
14249 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
14250 only if we wind up in a string from display property. (Bug#11063)
14252 * window.c (Fdelete_other_windows_internal): Invalidate the row
14253 and column information about mouse highlight, so that redisplay
14254 restores it after reallocating the glyph matrices. (Bug#7464)
14256 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
14257 string comes from a `display' text property, use the buffer
14258 position of that property as if we actually saw that position in
14260 (move_it_by_lines): Remove the assertion that
14261 "it->current_x == 0 && it->hpos == 0" which can be legitimately
14262 violated when there's a before-string at the beginning of a line.
14265 2012-03-30 Eli Zaretskii <eliz@gnu.org>
14267 * xdisp.c (append_space_for_newline): If the default face was
14268 remapped, use the remapped face for the appended newline.
14269 (extend_face_to_end_of_line): Use the remapped default face for
14270 extending the face to the end of the line.
14271 (display_line): Call extend_face_to_end_of_line when the default
14272 face was remapped. (Bug#11068)
14274 2012-03-29 Eli Zaretskii <eliz@gnu.org>
14276 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
14278 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
14280 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
14282 2012-03-27 Glenn Morris <rgm@gnu.org>
14284 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
14287 2012-03-26 Kenichi Handa <handa@m17n.org>
14289 * dispextern.h (struct glyph): Fix previous change. Change the
14290 bit length of glyphless.ch to 25 (Bug#11082).
14292 2012-03-26 Chong Yidong <cyd@gnu.org>
14294 * keyboard.c (Vselection_inhibit_update_commands): New variable.
14295 (command_loop_1): Use it; inhibit selection update for
14296 handle-select-window too (Bug#8996).
14298 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
14300 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
14302 2012-03-25 Kenichi Handa <handa@m17n.org>
14304 * dispextern.h (struct glyph): Change the bit length of
14305 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
14307 2012-03-24 Eli Zaretskii <eliz@gnu.org>
14309 * s/ms-w32.h (tzname): Include time.h before redirecting to
14310 _tzname. Fixes the MSVC build. (Bug#9960)
14312 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
14314 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
14317 * xterm.c (XTread_socket): Only modify handling_signal if
14318 !SYNC_INPUT. (Bug#11080)
14320 2012-03-23 Eli Zaretskii <eliz@gnu.org>
14322 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
14323 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
14324 when fetching a multibyte character consumes more bytes than
14325 CHAR_BYTES returns, due to unification of CJK characters in
14326 string_char. (Bug#11073)
14328 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
14330 * process.c (wait_reading_process_output): Handle pty disconnect
14331 by refraining from sending oneself a SIGCHLD (bug#10933).

14338 Mark string as coming from a prefix property.
14339 (handle_face_prop): Use default face for prefix strings (Bug#4281).
14340 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
14342 2012-03-21 Chong Yidong <cyd@gnu.org>
14344 * xfaces.c (Vface_remapping_alist): Doc fix.
14346 2012-03-20 Eli Zaretskii <eliz@gnu.org>
14348 * w32proc.c (Fw32_set_console_codepage)
14349 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

14354 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
14355 to reflect default non-nil value of redisplay-dont-pause.
14357 2012-03-19 Kenichi Handa <handa@m17n.org>
14359 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
14360 it fit in a valid range (Bug#11003).
14362 2012-03-18 Eli Zaretskii <eliz@gnu.org>
14364 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
14365 that is not from display property, accept the row as a "cursor
14366 row" if one of the string's character has a non-nil `cursor'
14367 property. Fixes cursor positioning when there are newlines in
14368 overlay strings, e.g. in icomplete.el. (Bug#11035)
14370 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
14372 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
14374 2012-03-12 Chong Yidong <cyd@gnu.org>
14376 * eval.c (inhibit_lisp_code): Rename from
14377 inhibit_window_configuration_change_hook; move from window.c.
14379 * xfns.c (unwind_create_frame_1, Fx_create_frame):
14380 * window.c (run_window_configuration_change_hook)
14381 (syms_of_window): Callers changed.

14401 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14404 2012-03-03 Glenn Morris <rgm@gnu.org>
14406 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14408 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14410 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14411 position past the first glyph_row that ends at ZV. (Bug#10902)
14412 (redisplay_window, next_element_from_string): Fix typos in
14414 (redisplay_window): Pass to move_it_vertically the margin in
14415 pixels, not in screen lines.
14417 2012-03-02 Glenn Morris <rgm@gnu.org>
14419 * buffer.c (buffer-list-update-hook): Doc fix.
14421 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14423 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14424 push_it before setting up the iterator for the first overlay
14425 string, even if we have an empty string loaded.
14426 (next_overlay_string): If there's an empty string on the iterator
14427 stack, pop the stack. (Bug#10903)
14429 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14431 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14432 Suggested by Stefan Monnier in
14433 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14434 * alloc.c (widen_to_Lisp_Object): New static function.
14435 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14436 and widening them to Lisp_Objects. This would work even if
14437 USE_LSB_TAG is defined and wide integers are used, which might
14438 happen in a future version of Emacs.
14440 2012-02-25 Chong Yidong <cyd@gnu.org>
14442 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14445 * xselect.c (Fx_selection_exists_p): Doc fix.

14447 before saving to clipboard manager.
14449 2012-02-24 Chong Yidong <cyd@gnu.org>
14451 * keyboard.c (process_special_events): Handle all X selection
14452 requests in kbd_buffer, not just the next one (Bug#8869).
14454 2012-02-23 Chong Yidong <cyd@gnu.org>
14456 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14457 call when setting menu-bar-lines and tool-bar-lines parameters.
14458 (unwind_create_frame_1): New helper function.

14479 when computing $valmask.
14481 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14482 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14483 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14484 It's useless in that case, and it can cause problems on hosts
14485 that allocate halves of EMACS_INT values separately.
14486 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14487 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14488 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14489 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14490 it avoids undefined behavior on hosts where shifting right by more
14491 than the word width has undefined behavior.
14493 2012-02-19 Chong Yidong <cyd@gnu.org>
14495 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14496 (Funhandled_file_name_directory, Ffile_name_as_directory)
14497 (Fdirectory_file_name, Fexpand_file_name)

14513 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14515 2012-02-15 Chong Yidong <cyd@gnu.org>
14517 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14518 marked as special. Also, starting docstrings with * is obsolete.

14533 2012-02-12 Chong Yidong <cyd@gnu.org>
14535 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14536 as that creates a dangerous corner case.
14538 * window.c (Fdelete_window_internal): Invalidate the mouse
14539 highlight (Bug#9904).
14541 2012-02-12 Glenn Morris <rgm@gnu.org>
14543 * xselect.c (Fx_own_selection_internal)
14544 (Fx_get_selection_internal, Fx_disown_selection_internal)
14545 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
14546 * nsselect.m (Fx_own_selection_internal)
14547 (Fx_disown_selection_internal, Fx_selection_exists_p)
14548 (Fx_selection_owner_p, Fx_get_selection_internal):
14549 Sync docs and argument specs with the xselect.c versions.
14551 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
14553 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
14555 2012-02-11 Eli Zaretskii <eliz@gnu.org>
14557 * w32select.c (Fx_selection_exists_p): Sync doc string and
14558 argument list with xselect.c. (Bug#10783)
14560 * w16select.c (Fx_selection_exists_p): Sync doc string and
14561 argument list with xselect.c. (Bug#10783)

14571 2012-02-07 Chong Yidong <cyd@gnu.org>
14573 * buffer.c (Fbuffer_local_variables)
14574 (buffer_lisp_local_variables): Handle unbound vars correctly;
14575 don't let Qunbound leak into Lisp.
14577 2012-02-07 Glenn Morris <rgm@gnu.org>
14579 * image.c (Fimagemagick_types): Doc fix.
14581 * image.c (imagemagick-render-type): Change it from a lisp object
14582 to an integer. Move the doc here from the lisp manual.
14583 Treat all values not equal to 0 the same.
14585 2012-02-06 Chong Yidong <cyd@gnu.org>
14587 * doc.c (store_function_docstring): Avoid applying docstring of
14588 alias to base function (Bug#2603).

14602 Include --enable-checking, if specified, in the return value.
14604 2012-02-04 Martin Rudalics <rudalics@gmx.at>
14606 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
14607 after rounding frame sizes. (Bug#9723)
14609 2012-02-04 Eli Zaretskii <eliz@gnu.org>

15092 (syms_of_search): Define `Sword_search_regexp'. (Bug#10145)
15094 2011-12-01 Stefan Monnier <monnier@iro.umontreal.ca>
15096 * fileio.c (Finsert_file_contents): Move after-change-function call
15097 to before the "handled:" label, since all "goto handled" appear in
15098 cases where the *-change-functions have already been properly called
15101 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
15103 * keyboard.c (interrupt_signal): Don't call kill-emacs when

15106 2011-11-30 Eli Zaretskii <eliz@gnu.org>
15108 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
15109 verifies glyph row's hash code--we have just reallocated the
15110 glyphs, so their contents can be complete garbage. (Bug#10164)
15112 2011-11-30 Juanma Barranquero <lekktu@gmail.com>
15114 * dispnew.c (adjust_glyph_matrix) [XASSERTS]: Add missing check.

15143 * dispnew.c (scrolling_window): Truncate overlaps in copy destination
15144 of scroll runs so as to avoid assigning disabled bogus rows and
15145 unnecessary graphics copy operations.
15147 2011-11-27 Eli Zaretskii <eliz@gnu.org>
15149 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.

15155 * lisp.h (GCTYPEBITS): Move before first use.
15156 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
15157 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in
15158 this macro definition.
15160 * s/ms-w32.h (tzname): Redirect to _tzname for all values of
15163 2011-11-27 Jan Djärv <jan.h.d@swipnet.se>

15176 Rename locals to avoid shadowing.
15177 * fileio.c (Finsert_file_contents):
15178 Rename inner 'gcpro1' to 'inner_gcpro1' to avoid shadowing.
15179 * process.c (wait_reading_process_output):
15180 Rename inner 'proc' to 'p' to avoid shadowing.
15181 Indent for consistency with usual Emacs style.
15183 2011-11-25 Eli Zaretskii <eliz@gnu.org>
15185 * xdisp.c (redisplay_window): If cursor row is not fully visible
15186 after recentering, and scroll-conservatively is set to a large
15187 number, scroll window by a few more lines to make the cursor fully
15188 visible and out of scroll-margin. (Bug#10105)
15189 (start_display): Don't move to the next line if the display should
15190 start at a newline that is part of a display vector or an overlay
15191 string. (Bug#10119)
15193 2011-11-24 Juri Linkov <juri@jurta.org>
15195 * image.c (imagemagick_load_image): Move `MagickSetResolution' down

15216 2011-11-22 Eli Zaretskii <eliz@gnu.org>
15218 * dispnew.c (adjust_glyph_matrix): Don't verify hash code of mode-
15219 and header-lines, as they don't have one computed for them.
15222 * .gdbinit (prow): Make displayed values more self-explaining.
15223 Add row's hash code.
15225 2011-11-21 Lars Magne Ingebrigtsen <larsi@gnus.org>

15268 2011-11-20 Paul Eggert <eggert@cs.ucla.edu>
15270 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
15271 Otherwise, valgrind does not work on some platforms.
15272 Problem reported by Andreas Schwab in
15273 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
15274 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
15275 is set, removing the need for VIRT_ADDRESS_VARIES.
15276 (PURE_P): Use a more-efficient implementation that needs just one
15277 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
15278 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
15279 to 4 (xorl, subq, cmpq, setbe).
15280 * alloc.c (pure): Always extern now, since that's the
15281 VIRT_ADDR_VARIES behavior.
15282 (PURE_POINTER_P): Use a single comparison, not two, for
15283 consistency with the new puresize.h.
15284 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
15285 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
15286 Remove VIRT_ADDR_VARIES no longer needed.

15291 (erase_phys_cursor, update_window_cursor, show_mouse_face)
15292 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
15293 behave as if the cursor position were at the window margin.
15295 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
15296 and the cursor position is out of bounds, behave as if the cursor
15297 position were at the window margin. (Bug#10075)
15299 2011-11-18 Chong Yidong <cyd@gnu.org>
15301 * window.c (Fwindow_combination_limit): Make first argument
15302 non-optional, since it is meaningless for live windows like the

15316 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
15317 hash values of the two rows.
15318 (copy_row_except_pointers): Preserve the used[] arrays and the
15319 hash values of the two rows. (Bug#10035)
15320 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
15322 * xdisp.c (row_hash): New function, body extracted from
15323 compute_line_metrics.
15324 (compute_line_metrics): Call row_hash, instead of computing the
15327 * dispnew.c (verify_row_hash): Call row_hash for computing the
15328 hash code of a row, instead of duplicating code from xdisp.c.
15330 * dispextern.h (row_hash): Add prototype.
15332 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
15334 * frame.c (delete_frame): Don't delete the terminal when the last
15335 X frame is closed if emacs is built with GTK toolkit.

15356 * window.c (Fwindow_nest): Rename to Fwindow_combination_limit.
15357 (Fset_window_nest): Rename to Fset_window_combination_limit.
15358 (Vwindow_nest): Rename to Vwindow_combination_limit.
15359 (recombine_windows, make_parent_window, make_window)
15360 (Fsplit_window_internal, saved_window)
15361 (Fset_window_configuration, save_window_save): Rename all
15362 occurrences of window_nest to window_combination_limit.
15364 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
15366 * image.c (imagemagick_load_image): Fix typo.
15368 2011-11-14 Eli Zaretskii <eliz@gnu.org>
15370 * xdisp.c (display_line): Move the call to
15371 highlight_trailing_whitespace before the call to
15372 compute_line_metrics, since the latter needs to see the final
15373 faces of all the glyphs to compute ROW's hash value.
15374 Fixes assertion violations in row_equal_p. (Bug#10035)
15376 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
15378 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
15379 just return (bug#10044).
15381 2011-11-12 Eli Zaretskii <eliz@gnu.org>
15383 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
15384 with user-defined heap size. Bump the default size of the temacs
15385 heap to 27MB, to avoid memory warning when running temacs.
15386 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
15388 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
15389 current_matrix and desired_matrix. (Bug#9990)
15390 (verify_row_hash) [XASSERTS]: New function.
15391 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
15392 that the hash value of glyph rows is correct.

15421 2011-11-11 Johan Bockgård <bojohan@gnu.org>
15423 * xdisp.c (fill_composite_glyph_string): Always set s->face, to
15424 avoid a crash (bug#9496).
15426 2011-11-09 Chong Yidong <cyd@gnu.org>
15428 * window.c (Fwindow_inside_edges, Fwindow_inside_pixel_edges)

15435 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
15437 Avoid some portability problems by eschewing 'extern inline' functions.
15438 The trivial performance wins aren't worth the portability hassles; see
15439 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15441 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
15442 (window_box_width, window_box_left, window_box_left_offset)
15443 (window_box_right, window_box_right_offset): Undo previous change,
15444 by removing the "extern"s.
15445 * intervals.c (adjust_intervals_for_insertion)
15446 (adjust_intervals_for_deletion): Undo previous change,
15447 making these static again.
15448 (offset_intervals, temp_set_point_both, temp_set_point)
15449 (copy_intervals_to_string): No longer inline.
15450 * xdisp.c (window_text_bottom_y, window_box_width)

15481 (delete_all_subwindows): Rename to delete_all_child_windows.
15482 (Fdelete_other_windows_internal, Fset_window_configuration):
15483 Call delete_all_child_windows instead of delete_all_subwindows.
15484 * frame.c (delete_frame): Call delete_all_child_windows instead

15487 2011-11-07 Paul Eggert <eggert@cs.ucla.edu>
15489 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
15490 This is also needed for porting to any host where GC_MARK_STACK is
15491 not GC_MAKE_GCPROS_NOOPS.
15492 (which_symbols): Use it.
15494 2011-11-07 Kenichi Handa <handa@m17n.org>
15496 * coding.c (coding_set_destination): Check coding->src_pos only
15497 when coding->src_object is a buffer (bug#9910).

15503 process_coding to 0 (bug#9912).
15505 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15507 * xmenu.c (cleanup_widget_value_tree): New function.
15508 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15509 calling free_menubar_widget_value_tree directly (Bug#9830).
15511 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
15513 Fix some portability problems with 'inline'.
15514 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
15515 (window_box_width, window_box_left, window_box_left_offset)
15516 (window_box_right, window_box_right_offset): Declare extern.
15517 Otherwise, these inline functions do not conform to C99 and
15518 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15519 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15520 * intervals.c (adjust_intervals_for_insertion)
15521 (adjust_intervals_for_deletion): Now extern, because otherwise the
15522 extern inline functions 'offset_intervals' couldn't refer to it.
15523 (static_offset_intervals): Remove.
15524 (offset_intervals): Rewrite using the old contents of
15525 static_offset_intervals. The old version didn't conform to C99
15526 because an extern inline function contained a reference to an
15527 identifier with static linkage.

15549 (Fwindow_vscroll): Doc fix.
15550 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
15551 argument, since it makes no sense to pass a live window and for
15552 consistency with window-child.

15764 instead of calling the "wide" APIs directly.
15766 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.

15819 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
15821 * sysdep.c (init_sys_modes): Fix the check for the controlling
15822 terminal (Bug#6649).
15824 2011-10-20 Eli Zaretskii <eliz@gnu.org>
15826 * dispextern.h (struct bidi_it): New member next_en_type.
15828 * bidi.c (bidi_line_init): Initialize the next_en_type member.
15829 (bidi_resolve_explicit_1): When next_en_pos is valid for the
15830 current character, check also for next_en_type being WEAK_EN.
15831 (bidi_resolve_weak): Don't enter the expensive loop if the current
15832 position is before next_en_pos. Record the bidi type of the first
15833 non-ET, non-BN character we find, in addition to its position.
15834 (bidi_level_of_next_char): Invalidate next_en_type when
15835 next_en_pos is over-stepped.
15837 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15839 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15840 * editfns.c: Rewrite current-time-zone so that it invokes
15841 the equivalent of (format-time-string "%Z") to get the time zone name.
15842 This fixes a bug when the time zone name contains characters that
15843 need converting from the system time locale to Emacs internal format.
15844 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15845 that patch fixed format-time-string to do the conversion, but
15846 I forgot to fix current-time-zone.
15847 (format_time_string): New function, containing most of
15848 what Fformat_time_string used to contain.
15849 (Fformat_time_string): Rewrite in terms of format_time_string.
15850 This doesn't change this function's behavior.
15851 (current-time-zone): Rewrite to use format_time_string.
15852 This fixes the bug reported by Michael Schierl in
15853 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15854 Jason Rumney's 2007-06-07 change worked around this bug, but
15856 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15858 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15860 * xdisp.c (start_display): If the character at POS is displayed
15861 via a display vector, reset IT->current.dpvec_index to zero.
15862 (try_window_reusing_current_matrix): If a line ends in a display
15863 vector or the next line starts in a display vector, continue
15864 redrawing the window even though the character position of
15865 start_row was reached.
15868 2011-10-18 Chong Yidong <cyd@gnu.org>
15870 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15871 with nobreak-char-display too.
15873 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15875 Fix part 3 of bug#9771.
15876 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15877 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15878 non-neutral characters if the current character is a paragraph
15879 separator (a.k.a. Newline). This avoids running the same
15880 expensive loop twice, once when we consume the preceding newline
15881 and the other time when the line actually needs to be displayed.
15882 Avoid the loop when we see neutrals on the base embedding level
15883 following a character whose directionality is the same as the
15884 paragraph's. This avoids running the expensive loop when a line
15885 ends in a long sequence of neutrals, like control characters.
15886 Add assertion against STRONG_AL type. Slightly rearrange code
15887 that determines the type of a neutral given the first non-neutral
15889 (bidi_level_of_next_char): Set next_en_pos to zero when
15890 invalidating its info.
15892 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15894 * xdisp.c (push_display_prop): Determine whether to record string
15895 or buffer position by IT->string, not by IT->method. Allow
15896 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15897 (move_it_vertically_backward): Don't look for character position
15898 immediately after the newline when in a continuation line.
15901 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15903 * window.c (coordinates_in_window): Rewrite and delabelize
15904 vertical border check. (Bug#5357) (Bug#9618)
15906 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15908 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15909 errors in XSetWindowBorder (bug#9310).
15911 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15913 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15914 avoid crash when xmalloc overrun checking is enabled.
15916 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15918 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15919 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15920 cursor motion with <left> and <right> arrow keys.
15922 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15923 some callers set that themselves.
15925 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15927 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15928 display string and the previous row comes from the same string and
15929 is empty. (Bug#9739) (Bug#9738)
15931 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15933 * doc.c (get_doc_string): Encode file name (bug#9735).
15935 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15937 * bidi.c (bidi_level_of_next_char):
15938 * xdisp.c (get_visually_first_element): Remove old incorrect
15939 comments regarding the Unicode Line Separator character.
15941 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15943 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15945 * alloc.c (Fgc_status): Do not access beyond zombies array
15946 boundary if nzombies > MAX_ZOMBIES.
15947 * alloc.c (dump_zombies): Add missing format specifier.
15949 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15951 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15952 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15954 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15955 Some packages use them to denote characters with modifiers.
15957 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15959 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15960 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15961 matching a pp-number. Rename parameter var to var1.
15963 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15965 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15967 2011-10-08 Glenn Morris <rgm@gnu.org>
15969 * callint.c (Fcall_interactively): Give a more explicit error for the
15970 'c' case with a non-character input. (Bug#8479)
15972 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15974 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15976 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15977 lines that are hscrolled on the left.
15979 * dispnew.c (buffer_posn_from_coords): Account for a possible
15980 presence of header-line. (Bug#4426)
15982 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15984 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15985 Don't advertise functionality which we discourage or doesn't work.
15987 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15989 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15990 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15991 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15992 this makes Emacs dump core during garbage collection on rare
15993 occasions. sizeof is obviously inferior to offsetof here, so
15994 stick with offsetof.
15995 (GC_POINTER_ALIGNMENT): New macro.
15996 (mark_memory): Omit 3rd (offset) arg; caller changed.
15997 Don't assume EMACS_INT alignment is the same as pointer alignment.
15999 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
16001 * keyboard.c (read_key_sequence_remapped): New var.
16002 (read_key_sequence): Compute remapping in the right buffer.
16003 (command_loop_1): Use read_key_sequence's remapping directly.
16005 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
16007 * dired.c (file_name_completion): Don't expand file name.
16008 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
16009 before checking file name handler.
16011 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
16012 they've been requested explicitly (bug#9591).
16014 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
16016 * keymap.c (Fsingle_key_description): Use make_specified_string
16017 instead of build_string to build string from push_key_description.
16020 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16022 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
16023 This fixes a Y2038 bug on 64-bit hosts.
16024 * buffer.c (reset_buffer):
16025 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
16026 (Fclear_buffer_auto_save_failure):
16027 Use 0, not -1, to represent an unset failure time, since time_t
16028 might not be signed.
16030 Remove dependency on glibc malloc internals.
16031 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16032 Move back here from lisp.h, but with their new implementations.
16033 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16034 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
16035 * charset.c (charset_table_init): New static var.
16036 (syms_of_charset): Use it instead of xmalloc. This removes a
16037 dependency on glibc malloc internals. See Eli Zaretskii's comment in
16038 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
16039 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16040 Move back to alloc.c.
16041 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16042 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
16044 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
16046 * nsterm.m (windowDidResize): Call x_set_window_size only when
16047 ns_in_resize is true. Otherwise set pixelwidth/height and
16048 call change_frame_size (Bug#9628).
16050 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
16052 Port --enable-checking=all to Fedora 14 x86-64.
16053 * charset.c (syms_of_charset): Also account for glibc malloc's
16054 internal overhead when calculating the initial malloc maximum.
16056 Port --enable-checking=all to Fedora 14 x86.
16057 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16059 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
16060 (overrun_check_realloc, overrun_check_free):
16061 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
16062 That way, xmalloc returns a properly-aligned pointer even if
16063 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
16064 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
16065 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
16066 into account when calculating the initial malloc maximum.
16067 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
16068 Move here from alloc.c, so that charset.c can use it too.
16069 Properly align; the old code wasn't right for common 32-bit hosts
16070 when configured with --enable-checking=all.
16071 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
16072 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
16074 2011-09-29 Eli Zaretskii <eliz@gnu.org>
16076 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
16079 2011-09-28 Eli Zaretskii <eliz@gnu.org>
16081 * xdisp.c (compute_display_string_end): If there's no display
16082 string at CHARPOS, return -1.
16084 * bidi.c (bidi_fetch_char): When compute_display_string_end
16085 returns a negative value, treat the character as a normal
16086 character not covered by a display string. (Bug#9624)
16088 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
16090 * lread.c (Fread_from_string): Fix typo in docstring.
16092 2011-09-27 Eli Zaretskii <eliz@gnu.org>
16094 * xdisp.c (handle_invisible_prop): If invisible text ends on a
16095 newline, reseat the iterator instead of bidi-iterating there one
16096 character at a time. (Bug#9610)
16097 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
16098 TO_CHARPOS if the bidi iterator is at base embedding level.
16100 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
16102 * lread.c (readevalloop): Use correct code for NBSP.
16103 (read1): Likewise. (Bug#9608)
16105 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
16107 * dbusbind.c (Fdbus_register_signal): When service is not
16108 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
16110 2011-09-25 Glenn Morris <rgm@gnu.org>
16112 * buffer.c (truncate-lines): Doc fix.
16114 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
16116 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
16117 (Fset_window_next_buffers): Doc fix.
16119 2011-09-24 Glenn Morris <rgm@gnu.org>
16121 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
16123 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
16125 Fix minor problems found by static checking.
16126 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
16127 * indent.c (Fvertical_motion): Fix == vs = typo.
16129 2011-09-24 Eli Zaretskii <eliz@gnu.org>
16131 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
16132 Default value is now t. Doc fix.
16134 * indent.c (Fvertical_motion): Compute and apply the overshoot
16135 logic when moving up, not only when moving down. Fix the
16136 confusing name and values of the it_overshoot_expected variable;
16137 logic changes accordingly. (Bug#9254) (Bug#9549)
16139 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
16140 CHARPOS is covered by a display string which includes newlines.
16141 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
16142 is covered by a display string with embedded newlines.
16144 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
16146 * dbusbind.c (Fdbus_register_signal): Add match rule to
16147 Vdbus_registered_objects_table. (Bug#9581)
16148 (Fdbus_register_method, Vdbus_registered_objects_table):
16151 2011-09-24 Jim Meyering <meyering@redhat.com>
16153 do not ignore write error for any output size
16154 The previous change was incomplete.
16155 While it makes emacs --batch detect the vast majority of stdout
16156 write failures, errors were still ignored whenever the output size is
16157 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
16158 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
16159 && echo FAIL: ignored write error
16160 FAIL: ignored write error
16161 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
16162 && echo FAIL: ignored write error
16163 FAIL: ignored write error
16164 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
16166 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
16168 * emacs.c (Fkill_emacs): In noninteractive mode exit
16169 non-successfully if a write error occurred on stdout. (Bug#9574)
16171 2011-09-21 Eli Zaretskii <eliz@gnu.org>
16173 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
16176 * dispextern.h (struct it): Update the comment documenting what
16179 2011-09-20 Eli Zaretskii <eliz@gnu.org>
16181 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
16182 a display string, extend search for cursor position to end of row.
16183 (find_row_edges): If the row ends in a newline from a display
16184 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
16185 Handle the case of a display string with multiple newlines.
16186 (Fcurrent_bidi_paragraph_direction): Fix search for previous
16187 non-empty line. Fixes confusing cursor motion with arrow keys at
16188 the beginning of a line that starts with whitespace.
16190 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
16192 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
16195 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
16197 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
16198 boolean (Bug#9154).
16200 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16202 * xdisp.c (display_line): Record maximum and minimum buffer
16203 positions even if no glyphs were produced (e.g., by a zero-width
16204 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
16205 buffer positions that will be removed from the glyph row because
16207 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
16208 column is beyond frame width: don't subtract 1 "pixel" when
16209 computing width of the stretch.
16210 (reseat_at_next_visible_line_start): Undo the change made on
16211 2011-09-17 that saved paragraph information and restored it after
16212 the call to `reseat'. (Bug#9545)
16214 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16216 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
16217 and turn window cursor on if cleared (Bug#9415).
16219 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
16221 * search.c (boyer_moore): Take unibyte characters from pattern
16222 literally. (Bug#9458)
16224 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16226 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
16228 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
16230 Fix minor problem found by static checking.
16231 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
16232 initialized, to pacify gcc -Wuninitialized.
16234 * fileio.c: Report proper errno when syscall falls.
16235 (Finsert_file_contents): Save and restore errno,
16236 so that report_file_error outputs the correct diagnostic.
16237 (Fwrite_region) [CLASH_DETECTION]: Likewise.
16239 2011-09-18 Eli Zaretskii <eliz@gnu.org>
16241 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
16243 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16245 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
16246 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
16248 2011-09-17 Eli Zaretskii <eliz@gnu.org>
16250 * xdisp.c (reseat_at_next_visible_line_start): Keep information
16251 about the current paragraph and restore it after the call to reseat.
16253 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
16254 (bidi_find_paragraph_start): Search back for paragraph beginning
16255 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
16256 (bidi_move_to_visually_next): Only trigger paragraph-related
16257 computations when the last character is a newline or at EOB, not
16258 just any NEUTRAL_B. (Bug#9470)
16260 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
16261 truncated lines if point is covered by a display string. (Bug#9524)
16263 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
16265 * xselect.c: Relax test for outgoing X longs (Bug#9498).
16266 (cons_to_x_long): New function.
16267 (lisp_data_to_selection_data): Use it. Correct the test for
16268 short-versus-long data; it was negated. Break out of vector
16269 loop, for efficiency, when a long datum is discovered.
16271 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
16273 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
16275 2011-09-16 Eli Zaretskii <eliz@gnu.org>
16277 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
16278 GCC PR/17406) by declaring this function with external scope.
16280 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16282 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
16283 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
16285 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
16287 * editfns.c (Fformat): Correctly handle text properties on "%%".

16296 (fill_composite_glyph_string): Add comments about special meaning
16297 of TAB characters in a composition.
16299 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
16301 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
16302 This occurs when processing a multibyte format.
16303 Problem reported by Wolfgang Jenker.
16305 2011-09-15 Johan Bockgård <bojohan@gnu.org>
16307 * xdisp.c (try_cursor_movement): Only check for exact match if
16308 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
16310 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16312 Remove unused external symbols.
16313 * dispextern.h (calc_pixel_width_or_height): Remove decl.
16314 * xdisp.c (calc_pixel_width_or_height): Now static.
16315 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
16316 * indent.c (check_display_width):
16317 * w32term.c: Fix comment to match code.
16318 * xterm.c, xterm.h (x_catching_errors): Remove.
16320 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
16322 * xselect.c: Use signed conversions more consistently (Bug#9498).
16323 (selection_data_to_lisp_data): Assume incoming selection data are
16324 signed integers, not unsigned. This is to be consistent with
16325 outgoing selection data, which was modified to use signed integers
16326 in as part of the fix to Bug#9196 in response to Jan D.'s comment
16327 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
16328 expects long, not unsigned long.
16330 2011-09-14 Eli Zaretskii <eliz@gnu.org>
16332 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
16333 computation of loop end. Reported by Johan Bockgård
16336 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
16338 * frame.c (Fother_visible_frames_p): Function deleted.
16340 2011-09-12 Eli Zaretskii <eliz@gnu.org>
16342 * indent.c (compute_motion): Process display vector front to back
16343 rather than the other way around. (Bug#2496)
16345 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
16347 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
16349 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
16351 * minibuf.c (Fread_from_minibuffer): Doc fix.
16353 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16355 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
16356 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
16358 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
16360 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
16361 value for non-existent files.
16363 2011-09-11 Eli Zaretskii <eliz@gnu.org>
16365 * fileio.c (Finsert_file_contents): If the file cannot be opened,
16366 set its "size" to -1. This will set the modtime_size field of
16367 the corresponding buffer to -1, which is what
16368 verify-visited-file-modtime expects for files that do not exist.
16371 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
16373 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
16375 * lisp.h: ... from here. push_key_description is no longer
16376 defined in keyboard.c, so its declaration should not be in
16377 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
16378 logically belongs with push_key_description.
16380 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
16382 * buffer.h: Include <sys/types.h> instead of <time.h>.
16383 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
16384 Problem reported by Herbert J. Skuhra.
16386 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
16388 * xml.c (parse_region): Make the parsing work for
16389 non-comment-starting XML files again (bug#9144).
16391 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
16393 * image.c (gif_load): Fix calculation of bottom and right corner.
16396 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16398 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16399 redisplay in small windows.
16401 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16403 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16405 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16407 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16408 Operate on live windows only.
16410 2011-09-08 Juanma Barranquero <lekktu@gmail.com>

16414 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16416 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16417 only under bidi iteration.
16419 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16421 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16423 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16425 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16426 Without this fix, the command to link temacs failed due to an
16427 undefined symbol __builtin_isnan. This is because
16428 /usr/include/iso/math_c99.h #defines isnan(x) to
16429 __builtin_isnan(x), but the bundled gcc, which identifies itself
16430 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16432 * floatfns.c (isnan): #undef, and then #define to a clone of
16434 (Fisnan): Always define, since it's always available now.
16435 (syms_of_floatfns): Always define isnan at the Lisp level.
16437 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16439 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16441 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16443 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16444 The previous code assumed that file offsets (off_t values) fit in
16445 EMACS_INT variables, which is not true on typical 32-bit hosts.
16446 The code messed up by falsely reporting buffer overflow in cases
16447 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16448 when "big" contains more than 2**29 bytes, even though this
16449 inserts just one byte and does not overflow the buffer.
16450 (Finsert_file_contents): Store file offsets as off_t
16451 values, not as EMACS_INT values. Check for overflow when
16452 converting between EMACS_INT and off_t. When checking for
16453 buffer overflow or for overlap, take the offsets into account.
16454 Don't use EMACS_INT for small values where int suffices.
16455 When checking for overlap, fix a typo: ZV was used where
16456 ZV_BYTE was intended.
16457 (Fwrite_region): Don't assume off_t fits into 'long'.
16458 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16460 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16462 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16464 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16466 sprintf-related integer and memory overflow issues (Bug#9412).
16468 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16469 (esprintf, exprintf, evxprintf): New functions.
16470 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16471 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16472 (modify_event_symbol): Do not assume that the length of
16473 name_alist_or_stem is safe to alloca and fits in int.
16474 (Fexecute_extended_command): Likewise for function name and binding.
16475 (Frecursion_depth): Wrap around reliably on integer overflow.
16476 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16477 since some callers pass EMACS_INT values.
16478 (Fsingle_key_description): Don't crash if symbol name contains more
16479 than MAX_ALLOCA bytes.
16480 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16481 (get_minibuffer): Arg is now EMACS_INT, not int.
16482 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16483 (esprintf, exprintf, evxprintf): New decls.
16484 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16486 * dbusbind.c (signature_cat): New function.
16487 (xd_signature, Fdbus_register_signal):
16488 Do not overrun buffer; instead, report string overflow.
16490 * dispnew.c (add_window_display_history): Don't overrun buffer.
16491 Truncate instead; this is OK since it's just a log.
16493 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16494 even if the time zone offset is outlandishly large.
16495 Don't mishandle offset == INT_MIN.
16497 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16498 when creating daemon; the previous buffer-overflow check was incorrect.
16500 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16501 which has the guts of the old verror function.
16503 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16504 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16506 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16507 (font_unparse_xlfd): Don't blindly alloca long strings.
16508 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16509 fits in int, when using sprintf. Use single snprintf to count
16510 length of string rather than counting it via multiple sprintfs;
16511 that's simpler and more reliable.
16512 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16513 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16514 sprintf, in case result does not fit in int.
16516 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16517 (fontset_from_font): Print it.
16519 * frame.c (tty_frame_count): Now printmax_t, not int.
16520 (make_terminal_frame, set_term_frame_name): Print it.
16521 (x_report_frame_params): In X, window IDs are unsigned long,
16522 not signed long, so print them as unsigned.
16523 (validate_x_resource_name): Check for implausibly long names,
16524 and don't assume name length fits in 'int'.
16525 (x_get_resource_string): Don't blindly alloca invocation name;
16526 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16529 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16530 (xg_check_special_colors, xg_set_geometry):
16531 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16533 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16534 Use esprintf, not sprintf, in case result does not fit in int.
16536 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16537 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16538 it as a large positive number.
16539 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16540 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16542 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16543 in case result does not fit in int.
16545 * print.c (float_to_string): Detect width overflow more reliably.
16546 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16547 buffer overrun. Don't assume list length fits in 'int'. Treat
16548 print length of 0 as 0, not as infinity; to be consistent with other
16549 uses of print length in this function. Don't overflow print length
16550 index. Don't assume hash table size fits in 'long', or that
16551 vectorlike size fits in 'unsigned long'.
16553 * process.c (make_process): Use printmax_t, not int, to format
16554 process-name gensyms.
16556 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16558 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16559 to avoid potential buffer overrun.
16561 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16562 if X resource line is longer than 512 bytes.
16564 * xfns.c (x_window): Make sprintf buffer a bit bigger
16565 to avoid potential buffer overrun.
16567 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16569 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16571 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16573 Integer overflow fixes for scrolling, etc.
16574 Without these, Emacs silently mishandles large integers sometimes.
16575 For example, "C-u 4294967297 M-x recenter" was treated as if
16576 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16578 * xdisp.c (try_window_id): Check Emacs fixnum range before
16579 converting to 'int'.
16581 * window.c (window_scroll_line_based, Frecenter):
16582 Check that an Emacs fixnum is in range before assigning it to 'int'.
16583 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16584 values converted from Emacs fixnums.
16585 (Frecenter): Don't wrap around a line count if it is out of 'int'
16586 range; instead, treat it as an extreme value.
16587 (Fset_window_configuration, compare_window_configurations):
16588 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16590 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16591 that can exceed INT_MAX. Check that EMACS_INT value is in range
16592 before assigning it to the (possibly-narrower) index.
16593 (match_limit): Don't assume that a fixnum can fit in 'int'.
16595 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16598 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16599 (Fvertical_motion): Don't wrap around LINES values that don't fit
16600 in 'int'. Instead, treat them as extreme values. This is good
16601 enough for windows, which can't have more than INT_MAX lines anyway.
16603 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16605 * Require libxml/parser.h to avoid compilation warning.
16607 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16609 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16610 since this reportedly can destroy thread storage.
16612 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16614 * syntax.c (find_defun_start): Update all cache variables if
16615 exiting early (Bug#9401).
16617 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16619 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16621 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16622 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16623 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16625 * term.c (tty_append_glyph): New function.
16626 (produce_stretch_glyph): Static function and its prototype deleted.
16628 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16631 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16633 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16634 when checking :margin (Bug#9390).
16635 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16636 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16637 so that the name doesn't mislead. All uses changed.
16639 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16641 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16644 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16646 * xdisp.c (move_it_to): Don't bail out early when reaching
16647 position beyond to_charpos, if we are scanning backwards.
16648 (move_it_vertically_backward): When DY == 0, make sure we get to
16649 the first character in the line after the newline.
16651 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16653 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16654 (ccl_driver): Do not generate an out-of-range pointer.
16655 (Fccl_execute_on_string): Remove unnecessary check for
16656 integer overflow, noted by Stefan Monnier in
16657 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16658 Remove a FIXME that didn't need fixing.
16659 Simplify the newly-introduced buffer reallocation code.
16661 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16663 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16665 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16667 Integer and memory overflow issues (Bug#9196).
16669 * doc.c (get_doc_string): Rework so that
16670 get_doc_string_buffer_size is the actual buffer size, rather than
16671 being 1 less than the actual buffer size; this makes xpalloc more
16674 * image.c (x_allocate_bitmap_record, cache_image):
16675 * xselect.c (Fx_register_dnd_atom):
16676 Simplify previous changes by using xpalloc.
16678 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16679 since either will do and ptrdiff_t is convenient with xpalloc.
16681 * charset.c (charset_table_size)
16682 (struct charset_sort_data.priority): Now ptrdiff_t.
16683 (charset_compare): Don't overflow if priorities differ greatly.
16684 (Fsort_charsets): Don't assume list length fits in int.
16685 Check for size-calculation overflow when allocating sort data.
16686 (syms_of_charset): Allocate an initial charset table that is
16687 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16689 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16691 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16692 The actual value is always <= INT_MAX, and leaving it unsigned made
16693 overflow checking harder.
16695 * dispextern.h (struct glyph_matrix.rows_allocated)
16696 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16697 with xpalloc. The values are still always <= INT_MAX.
16699 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16701 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16702 (SAFE_NALLOCA): New macro.
16704 * region-cache.c (struct boundary.pos, find_cache_boundary)
16705 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16706 (set_cache_region, invalidate_region_cache)
16707 (revalidate_region_cache, know_region_cache, region_cache_forward)
16708 (region_cache_backward, pp_cache):
16709 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16710 so that ptrdiff_t * can be passed to xpalloc.
16711 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16712 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16713 (pp_cache): Don't assume cache_len fits in int.
16714 * region-cache.h: Adjust extern decls to match.
16716 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16717 EMACS_INT, since either will do, for xpalloc.
16719 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16720 (xnmalloc, xnrealloc, xpalloc): New functions.
16722 * bidi.c (bidi_shelve_header_size): New constant.
16723 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16724 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16726 * bidi.c (bidi_cache_shrink):
16727 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16729 Don't update size of array until after memory allocation succeeds,
16730 because xmalloc/xrealloc may not return.
16731 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16732 now that we have proper integer overflow checking.
16733 (record_overlay_string, overlay_strings): Catch overflows when
16734 calculating size of overlay_str_buf.
16736 * callproc.c (Fcall_process): Check for size overflow when
16737 calculating size of args2.
16738 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16739 Normally we prefer signed values, but sticking with ptrdiff_t would
16740 require adding more-complicated checks.
16742 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16743 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16744 Redo buffer-overflow calculations to avoid integer overflow.
16745 Add a FIXME comment where memory seems to be over-allocated.
16747 * character.c (Fstring): Check for size-calculation overflow.
16749 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16750 unnecessary integer overflow. Check for size overflow.
16751 (encode_coding_object): Don't update size until xmalloc succeeds.
16753 * composite.c (get_composition_id): Check for overflow in glyph
16754 length calculations.
16756 Integer and memory overflow fixes for display code.
16757 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16758 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16759 (scrolling_window): Check for overflow in size calculations.
16760 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16761 Don't assume glyph table len fits in int.

16763 (row_table_size): Now ptrdiff_t, not int.
16764 (scrolling_window): Avoid overflow in size calculations.
16765 Don't update size until allocation succeeds.
16766 * fns.c (concat): Check for overflow in size calculations.
16767 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16768 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16769 (NEXT_ALMOST_PRIME_LIMIT): New constant.
16771 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16772 (get_doc_string): Check for size calculation overflow.
16773 Don't update size until allocation succeeds.
16774 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16775 EMACS_INT, where ptrdiff_t will do.
16776 (Fsubstitute_command_keys): Check for string overflow.
16778 * editfns.c (set_time_zone_rule): Don't assume environment length
16780 (message_length): Now ptrdiff_t, not int.
16781 (Fmessage_box): Don't update size until allocation succeeds.
16782 Don't assume message length fits in int.
16783 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16785 * emacs.c (main): Do not reallocate argv, since there is a null at
16786 the end that can be overwritten, and this way there's no need to
16787 worry about size-calculation overflow.
16788 (sort_args): Check for size-calculation overflow.
16790 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16792 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16794 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16795 (x_set_scroll_bar_width, x_figure_window_size):
16796 Check for integer overflow.
16797 (x_set_alpha): Do not assume XINT fits in int.
16799 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16800 This is for the members text_lines, text_cols, total_lines, total_cols,
16801 where the system imposes an 'int' limit.
16803 * fringe.c (Fdefine_fringe_bitmap):
16804 Don't update size until alloc works.
16806 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16807 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16809 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16810 Check for size-calculation overflow.
16811 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16812 do, as we prefer signed integers.
16813 (id_to_widget.max_size, id_to_widget.used)
16814 (xg_store_widget_in_map, xg_remove_widget_from_map)
16815 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16816 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16817 Use and return ptrdiff_t, not int.
16818 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16819 * gtkutil.h: Change prototypes to match the above.
16821 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16822 are duplicate now that they've been promoted to lisp.h.
16823 (x_allocate_bitmap_record, x_alloc_image_color)
16824 (make_image_cache, cache_image, xpm_load):
16825 Don't update size until alloc is done.

16835 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16836 Use ptrdiff_t, not int, to count maps.

16838 calculations. Don't update size until allocation succeeds.
16839 Redo calculations to avoid overflow.
16840 * keyboard.h: Change prototypes to match the above.
16842 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16844 (current_minor_maps): Check for size calculation overflow.
16845 * keymap.h: Change prototypes to match the above.
16847 * lread.c (read1, init_obarray): Don't update size until alloc done.
16849 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.

16868 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16869 for command line length. Do not attempt to address one before the
16870 beginning of an array, as that's not portable.

16873 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
16875 (encode_terminal_code, calculate_costs): Check for size
16876 calculation overflow.
16877 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

16898 Use ptrdiff_t, not int, for sizes.
16899 (Finternal_make_lisp_face, cache_face):
16900 Check for size calculation overflow.
16901 (cache_face): Treat size calculation overflows as if they were
16902 memory exhaustion (the usual treatment), rather than aborting.
16904 * xfns.c (x_encode_text, x_set_name_internal)
16905 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16906 sizes, since they can exceed INT_MAX in size. Check for size
16907 calculation overflow.
16909 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16910 (xg_select): Check for size calculation overflow.
16911 Don't update size until alloc done.
16913 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16914 as sprintf is limited to int lengths.
16916 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16917 (X_LONG_MIN): New macros.
16918 Use them to make the following changes clearer.
16919 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16920 This change doesn't affect the value now, but it may help remind
16921 future maintainers not to raise the value too much later.
16922 (SELECTION_QUANTUM): Remove, replacing with ...
16923 (selection_quantum): ... new function, which avoids overflow.
16925 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16926 assumption that selection length fits in 'int'.
16927 (x_reply_selection_request, x_handle_selection_request)
16928 (x_get_window_property, receive_incremental_selection)
16929 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
16930 (lisp_data_to_selection_data, clean_local_selection_data):
16931 Use ptrdiff_t, not int, to record length of selection.
16932 (x_reply_selection_request, x_get_window_property)
16933 (receive_incremental_selection, x_property_data_to_lisp):
16934 Redo calculations to avoid overflow.
16935 (x_reply_selection_request): When sending hint, ceiling it at
16936 X_LONG_MAX rather than relying on wraparound overflow to send
16938 (x_get_window_property, receive_incremental_selection)
16939 (lisp_data_to_selection_data, x_property_data_to_lisp):
16940 Check for size-calculation overflow.
16941 (x_get_window_property, receive_incremental_selection)

16943 Don't store size until memory allocation succeeds.
16944 (x_get_window_property): Plug memory leak on memory exhaustion.
16945 Don't double-block input; malloc is safe here. Don't assume 2**34
16946 - 4 fits in unsigned long. Add an xassert to check
16947 XGetWindowProperty overflow. Be more careful about overflow
16948 calculations, and distinguish size from memory overflow better.
16949 (receive_incremental_selection): When tracing, don't assume
16950 unsigned int is less than INT_MAX.
16951 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
16952 harmful) conversions of unsigned short to int.
16953 (lisp_data_to_selection_data): Don't assume that integers
16954 in the range -65535 through -1 fit in an X unsigned short.
16955 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16956 result parameters unless successful. Rely on cons_to_unsigned
16957 to report problems with elements; the old code wasn't right anyway.
16958 (x_check_property_data): Check for int overflow; we cannot use
16959 a wider type due to X limits.
16960 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
16962 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
16964 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
16965 (x_term_init): Check for size calculation overflow.
16966 (x_color_cells): Don't store size until memory allocation succeeds.
16967 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
16968 Don't assume alloca size is less than MAX_ALLOCA.
16969 (x_term_init): Don't assume length fits in int (sprintf is limited
16972 Use ptrdiff_t for composition IDs.
16973 * character.c (lisp_string_width):
16974 * composite.c (composition_table_size, n_compositions)
16975 (get_composition_id, composition_gstring_from_id):

16991 * image.c (xpm_get_color_table_h):
16992 * lisp.h (hash_lookup, hash_put):
16993 * minibuf.c (Ftest_completion):
16994 Use ptrdiff_t for hash table indexes, not int (which is too
16995 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16996 32-bit --with-wide-int hosts).
16998 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16999 Add a FIXME comment about memory leaks.
17000 (syms_of_charset): Don't assume xmalloc returns.

17004 * character.h (CHAR_WIDTH):
17005 * indent.c (MULTIBYTE_BYTES_WIDTH):
17006 Use sanitize_char_width to avoid undefined and/or bad behavior
17007 with outlandish widths.
17008 * character.h (sanitize_tab_width): Rename from sanitize_width,
17009 now that we have two such functions. All uses changed.
17010 (sanitize_char_width): New inline function.
17012 Don't assume that tab-width fits in int.
17013 * character.h (sanitize_width): New inline function.
17014 (SANE_TAB_WIDTH): New macro.
17015 (ASCII_CHAR_WIDTH): Use it.

17020 * fileio.c: Integer overflow issues with file modes.
17021 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
17023 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
17024 Remove unreachable code.
17025 (read_hex, load_charset_map_from_file): Check for integer overflow.
17027 * xterm.c: Don't go over XClientMessageEvent limit.
17028 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
17029 (x_send_scroll_bar_event): Likewise. Check that the size does not
17030 exceed limits imposed by XClientMessageEvent, as well as the usual
17031 ptrdiff_t and size_t limits.
17033 * keyboard.c: Overflow, signedness and related fixes.
17034 (make_lispy_movement): Use same integer type in forward decl
17035 that is used in the definition.
17036 (read_key_sequence, keyremap_step):
17037 Change bufsize argument back to int, undoing my 2011-03-30 change.
17038 We prefer signed types, and int is wide enough here.
17039 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
17040 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
17041 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
17042 length, not size_t. Use ptrdiff_t for index, not int.
17043 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
17044 possibility of integer overflow.
17046 Overflow, signedness and related fixes for images.
17048 * dispextern.h (struct it.stack[0].u.image.image_id)
17049 (struct_it.image_id, struct image.id, struct image_cache.size)

17056 * xdisp.c (calc_pixel_width_or_height):
17057 * xfns.c (image_cache_refcount):
17058 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

17065 when the callers expect that.
17066 (image_ascent): Redo ascent calculation to avoid int overflow.
17067 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
17068 (lookup_image): Remove unnecessary tests.
17069 (xbm_image_p): Locals are now of int, not EMACS_INT,
17070 since parse_image_check makes sure they fit into int.
17071 (png_load, gif_load, svg_load_image):
17072 Prefer int to unsigned where either will do.
17073 (tiff_handler): New function, combining the cores of the
17074 old tiff_error_handler and tiff_warning_handler.
17075 This function is rewritten to use vsnprintf and thereby avoid
17076 stack buffer overflows. It uses only the features of vsnprintf
17077 that are common to both POSIX and native Microsoft.
17078 (tiff_error_handler, tiff_warning_handler): Use it.
17079 (tiff_load, gif_load, imagemagick_load_image):
17080 Don't assume :index value fits in 'int'.
17081 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
17082 (imagemagick_load_image): Check that crop parameters fit into
17083 the integer types that MagickCropImage accepts. Don't assume
17084 Vimagemagick_render_type has a nonnegative value. Don't assume
17085 size_t fits in 'long'.
17086 (gs_load): Use printmax_t to print the widest integers possible.
17087 Check for integer overflow when computing image height and width.
17089 2011-08-26 Eli Zaretskii <eliz@gnu.org>
17091 * xdisp.c (redisplay_window): Don't force window start if point
17092 will be invisible in the resulting window. (Bug#9324)

17096 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
17097 the display spec is of the form `(space ...)'.
17098 (handle_display_spec): Return the value returned by
17099 handle_single_display_spec, not just 1 or zero.
17100 (handle_single_display_spec): If the display spec is of the form
17101 `(space ...)', and specifies display in the text area, return 2
17103 (try_cursor_movement): Check for the need to scroll more
17104 accurately, and prefer exact match for point under bidi.
17105 Don't advance `row' beyond the last row of the window.
17107 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
17108 into disp_prop; all users changed.
17110 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
17111 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
17112 for the text covered by the display property.

17122 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
17123 buffers, return left-to-right.
17124 (set_cursor_from_row): Consider candidate row a win if its glyph
17125 represents a newline and point is on that newline. Fixes cursor
17126 positioning on the newline at EOL of R2L text within L2R
17127 paragraph, and vice versa.
17128 (try_cursor_movement): Check continued rows, in addition to
17129 continuation rows. Fixes unwarranted scroll when point enters a
17130 continued line of R2L text within an L2R paragraph, or vice versa.
17131 (cursor_row_p): Consider the case of point being equal to
17132 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
17133 from the end of a short line to the beginning of a continued line
17134 of R2L text within L2R paragraph.
17135 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
17136 composed characters.
17138 * bidi.c (bidi_check_type): Use xassert.

17149 * nsfont.m (ns_otf_to_script): Fix typo.
17151 2011-08-22 Kenichi Handa <handa@m17n.org>
17153 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
17154 extra slot even if the purpose is char-code-property-table.
17156 2011-08-23 Eli Zaretskii <eliz@gnu.org>
17158 * xdisp.c (redisplay_window): When computing centering_position,
17159 account for the height of the header line. (Bug#8874)
17161 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
17162 instead of CHAR_TO_BYTE. Fixes a crash when a completion
17163 candidate is selected by the mouse, and that candidate has a
17164 composed character under the mouse.
17166 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
17167 coordinates reported by pos-visible-in-window-p for a composed
17168 character in column zero.
17170 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
17172 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
17174 2011-08-22 Eli Zaretskii <eliz@gnu.org>
17176 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
17177 consider it a hit if to_charpos is anywhere in the range of the
17178 composed buffer positions.
17180 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
17182 * image.c (gif_load): Don't assume that each subimage has the same
17183 dimensions as the base image. Handle disposal method that is
17184 "undefined" by the gif spec (Bug#9335).
17186 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
17188 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

17191 2011-08-19 Eli Zaretskii <eliz@gnu.org>
17193 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
17194 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
17195 from an Org mode buffer to a Speedbar frame.
17197 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
17198 a composition, take its buffer position from IT->cmp_it.charpos.
17199 Fixes cursor positioning at the beginning of a line that begins
17200 with a composed character.
17202 2011-08-18 Eli Zaretskii <eliz@gnu.org>
17204 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
17205 character bidirectional type, use STRONG_L instead. Fixes crashes
17206 in a buffer produced by `describe-categories'.
17208 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
17209 members before the level stack, so they would be saved and
17210 restored when copying iterator state. Fixes incorrect reordering
17211 around TABs covered by display properties.
17213 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
17215 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

17223 2011-08-17 Eli Zaretskii <eliz@gnu.org>
17225 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
17226 has no `load' handler, try opening the file locally. (Bug#9311)
17228 2011-08-16 Ken Brown <kbrown@cornell.edu>

17239 Fix memory allocation problems in Cygwin build (Bug#9273).
17241 * unexcw.c ( __malloc_initialized): Declare external variable.
17242 (fixup_executable): Force the dumped emacs to reinitialize malloc.
17244 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
17246 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the

17283 2011-08-14 Eli Zaretskii <eliz@gnu.org>
17285 * xdisp.c (move_it_in_display_line_to): Don't invoke
17286 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
17287 ppos_it. Fixes vertical cursor motion when line beginning is
17288 covered by an image. (Bug#9296)
17290 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
17292 * nsterm.h (ns_run_ascript): Declare.

17295 * nsfns.m (as_script, as_result, as_status): New static variables.
17296 (ns_run_ascript): New function.
17297 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
17298 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
17299 the event loop. Get status from as_status (Bug#7276).
17301 * nsterm.m (sendEvent): If event is NSApplicationDefined and
17302 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
17303 the event loop (Bug#7276).
17305 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
17307 * gnutls.c (QCgnutls_bootprop_priority)

17328 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
17329 (Fnetwork_interface_list): Allocate in increments of bytes instead
17330 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
17331 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
17333 (struct ifflag_def): notrailers is smart on OSX.
17334 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
17335 Get hardware address with getifaddrs if available.
17337 2011-08-12 Eli Zaretskii <eliz@gnu.org>
17339 * xdisp.c (iterate_out_of_display_property): xassert that
17340 IT->position is set to within IT->object's boundaries. Break from
17341 the loop as soon as EOB is reached; avoids infloops in redisplay
17342 when IT->position is set up wrongly due to some bug.
17343 Set IT->current to match the bidi iterator unconditionally.
17344 (push_display_prop): Allow GET_FROM_STRING as IT->method on
17345 entry. Force push_it to save on the stack the current
17346 buffer/string position, to be restored by pop_it. Fix flags in
17347 the iterator structure wrt the object coming from a display
17348 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
17349 properties. (Bug#9284)
17351 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
17353 * fontset.c (fontset_get_font_group): Add proper type checks.
17356 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
17358 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
17359 and LC_VERSION_MIN_MACOSX.

17361 (dump_it) [LC_FUNCTION_STARTS]: Use it.
17363 2011-08-08 Eli Zaretskii <eliz@gnu.org>
17365 * xdisp.c (forward_to_next_line_start): Allow to use the
17366 no-display-properties-and-no-overlays under bidi display.
17367 Set disp_pos in the bidi iterator to avoid searches for display
17368 properties and overlays.
17370 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
17372 * editfns.c (Fset_time_zone_rule): Document relationship with the
17375 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
17376 the font entity extracted from the cache (Bug#8109).
17378 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
17380 * composite.c (autocmp_chars): Don't reset point. That is done by
17381 restore_point_unwind (Bug#5984).
17383 2011-08-07 Juri Linkov <juri@jurta.org>
17385 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
17386 to show the arg `TIME' instead of `TIMEVAL'.
17388 2011-08-06 Eli Zaretskii <eliz@gnu.org>
17390 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
17391 display property strides EOL and includes a newline, as in
17392 longlines-mode. (Bug#9254)
17393 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
17394 word-wrap under bidirectional display. (Bug#9224)
17396 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
17397 is non-zero, even if the data buffer is NULL. Fixes a crash in
17398 vertical-motion with longlines-mode. (Bug#9254)
17400 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17402 * bidi.c <bidi_cache_total_alloc>: Now static.
17403 (bidi_initialize): Initialize bidi_cache_total_alloc.
17405 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17408 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17409 amount allocated this far in `bidi_cache_total_alloc'.
17410 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17411 non-zero, only free the data buffer without restoring the cache
17412 contents. All callers changed.
17414 * dispextern.h (bidi_unshelve_cache): Update prototype.
17416 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17417 (move_it_in_display_line, move_it_to)
17418 (move_it_vertically_backward, move_it_by_lines): Replace the call
17419 to xfree to an equivalent call to bidi_unshelve_cache.
17420 (move_it_in_display_line_to): Fix logic of returning
17421 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17423 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17425 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17426 came from a string character with a `cursor' property. (Bug#9229)
17428 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17430 * Makefile.in (LIB_PTHREAD): New variable.
17431 (LIBES): Add LIB_PTHREAD (Bug#9216).
17433 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17434 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17436 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17438 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17440 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17442 * xterm.c (x_find_topmost_parent): New function.
17443 (x_set_frame_alpha): Find topmost parent window with
17444 x_find_topmost_parent and set the property there also (bug#9181).
17445 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17447 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17449 * callproc.c (Fcall_process): Avoid vfork clobbering
17450 the local vars buffer, coding_systems, current_dir.
17452 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17454 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17456 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17458 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17459 so that it is not optimized away.
17461 * xdisp.c (compute_display_string_pos): Remove unused local.
17463 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17465 Fix slow cursor motion and scrolling in large buffers with
17466 selective display, like Org Mode buffers. (Bug#9218)
17468 * dispextern.h (struct bidi_it): New member disp_prop_p.
17470 * xdisp.c: Remove one-slot cache of display string positions.
17471 (compute_display_string_pos): Accept an additional argument
17472 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17473 for a display string or property. If found, set DISP_PROP_P
17476 * bidi.c (bidi_fetch_char): Accept an additional argument
17477 DISP_PROP_P, and pass it to compute_display_string_pos.
17478 Only handle text covered by a display string if DISP_PROP_P is returned
17479 non-zero. All callers of bidi_fetch_char changed.
17481 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17483 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17485 2010-12-03 Don March <don@ohspite.net>
17487 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17488 last character M-[char] is translated to ESC [char] (bug#7541).
17490 2011-08-02 Kenichi Handa <handa@m17n.org>
17492 * lisp.h (uniprop_table): Extern it.
17494 * chartab.c (uniprop_table): Make it non-static.
17496 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17498 * xdisp.c (forward_to_next_line_start): Accept additional argument
17499 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17501 (reseat_at_next_visible_line_start): Use the bidi iterator state
17502 returned by forward_to_next_line_start to restore the state of
17503 it->bidi_it after backing up to previous newline. (Bug#9212)
17505 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17507 * regex.c (re_comp): Protoize.
17508 (re_exec): Fix return type.
17509 (regexec): Fix type of `ret'. (Bug#9203)
17511 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17513 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17514 This is needed if max-image-size is a floating-point number.
17516 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17518 * print.c (print_object): Print empty symbol as ##.
17520 * lread.c (read1): Read ## as empty symbol.
17522 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17524 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17525 setting frame foreground color (Bug#9175).
17526 (x_set_background_color): Likewise.
17528 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17529 contents (Bug#9176).
17530 (EmacsTooltip -init): Remove bezels and add shadows to
17533 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17534 or scroll bar (Bug#8470).
17536 * nsfont.m (nsfont_open): Remove assignment to voffset and
17537 unnecessary vars hshink, expand, hd, full_height, min_height.
17538 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17540 * nsterm.h (nsfont_info): Remove voffset field.
17542 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17544 Implement strike-through and overline on NextStep (Bug#8863).
17546 * nsfont.m (nsfont_open): Use underline position provided by font,
17547 instead of hard-coded value of 2.
17548 (nsfont_draw): Call ns_draw_text_decoration instead.
17550 * nsterm.h: Add declaration for ns_draw_text_decoration.
17552 * nsterm.m (ns_draw_text_decoration): New function for drawing
17553 underline, overline, and strike-through.
17554 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17555 ns_draw_text_decoration. Change treatment of cursor drawing to
17556 accommodate underlining, etc.
17558 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17560 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17563 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17565 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17566 Without this fix, if a signal arrives just after memory fills up,
17567 'malloc' might be invoked reentrantly.
17569 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17570 In other words, assume that every image size is allowed, on non-X
17571 hosts. This assumption is probably wrong, but it lets Emacs compile.
17573 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17575 * regex.c (re_iswctype): Convert return values to boolean.
17577 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17579 * xdisp.c (compute_display_string_pos): Don't use cached display
17580 string position if the buffer had its restriction changed.
17583 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17585 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17587 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17589 Integer signedness and overflow and related fixes. (Bug#9079)
17591 * bidi.c: Integer size and overflow fixes.
17592 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17593 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17594 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17595 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17596 (bidi_find_other_level_edge):
17597 Use ptrdiff_t instead of EMACS_INT where either will do.
17598 This works better on 32-bit hosts configured --with-wide-int.
17599 (bidi_cache_ensure_space): Check for size-calculation overflow.
17600 Use % rather than repeated addition, for better worst-case speed.
17601 Don't set bidi_cache_size until after xrealloc returns, because it
17603 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17604 (bidi_cache_ensure_space): Also check that the bidi cache size
17605 does not exceed that of the largest Lisp string or buffer. See Eli
17606 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17608 * alloc.c (__malloc_size_t): Remove.
17609 All uses replaced by size_t. See Andreas Schwab's note
17610 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17612 * image.c: Improve checking for integer overflow.
17613 (check_image_size): Assume that f is nonnull, since
17614 it is always nonnull in practice. This is one less thing to
17615 worry about when checking for integer overflow later.
17616 (x_check_image_size): New function, which checks for integer
17617 overflow issues inside X.
17618 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17619 This removes the need for a memory_full check.
17620 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17621 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17622 (xbm_read_bitmap_data): Change locals back to 'int', since
17623 their values must fit in 'int'.
17624 (xpm_load_image, png_load, tiff_load):
17625 Invoke x_create_x_image_and_pixmap earlier,
17626 to avoid much needless work if the image is too large.
17627 (tiff_load): Treat overly large images as if
17628 x_create_x_image_and_pixmap failed, not as malloc failures.
17629 (gs_load): Use x_check_image_size.
17631 * gtkutil.c: Omit integer casts.
17632 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17633 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17635 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17637 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17638 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17639 would wrongly return t on a 64-bit host.
17641 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17642 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17643 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17644 and therefore cause GCC to emit a bogus diagnostic in some cases.
17646 * image.c: Integer signedness and overflow and related fixes.
17647 This is not an exhaustive set of fixes, but it's time to
17648 record what I've got.
17649 (lookup_pixel_color, check_image_size): Remove redundant decls.
17650 (check_image_size): Don't assume that arbitrary EMACS_INT values
17651 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17652 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17653 (tiff_load, imagemagick_load_image):
17654 Check for overflow in size calculations.
17655 (x_create_x_image_and_pixmap): Remove unnecessary test for
17656 xmalloc returning NULL; that can't happen.
17657 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17658 (xpm_color_bucket): Use better integer hashing function.
17659 (xpm_cache_color): Don't possibly over-allocate memory.
17660 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17661 (gif_memory_source):
17662 Use ptrdiff_t, not int or size_t, to record sizes.
17663 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17664 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17665 either works, as we prefer signed integers.
17666 (tiff_read_from_memory, tiff_write_from_memory):
17667 Return tsize_t, not size_t, since that's what the TIFF API wants.
17668 (tiff_read_from_memory): Don't fail simply because the read would
17669 go past EOF; instead, return a short read.
17670 (tiff_load): Omit no-longer-needed casts.
17671 (Fimagemagick_types): Don't assume size fits into 'int'.
17673 Improve hashing quality when configured --with-wide-int.
17674 * fns.c (hash_string): New function, taken from sxhash_string.
17675 Do not discard information about ASCII character case; this
17676 discarding is no longer needed.
17677 (sxhash-string): Use it. Change sig to match it. Caller changed.
17678 * lisp.h: Declare it.
17679 * lread.c (hash_string): Remove, since we now use fns.c's version.
17680 The fns.c version returns a wider integer if --with-wide-int is
17681 specified, so this should help the quality of the hashing a bit.
17683 * emacs.c: Integer overflow minor fix.
17684 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17685 Define only if GNU_LINUX.
17686 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17688 * dispnew.c: Integer signedness and overflow fixes.
17689 Remove unnecessary forward decls, that were a maintenance hassle.
17690 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17692 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17693 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17694 (prepare_desired_row, line_draw_cost):
17695 Use int, not unsigned, where either works.
17696 (save_current_matrix, restore_current_matrix):
17697 Use ptrdiff_t, not size_t, where either works.
17698 (init_display): Check for overflow more accurately, and without
17699 relying on undefined behavior.
17701 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17702 Remove, replacing with the new symbols in lisp.h. All uses changed.
17703 * fileio.c (make_temp_name):
17704 * filelock.c (lock_file_1, lock_file):
17705 * xdisp.c (message_dolog):
17706 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17707 Use pMd etc. instead.
17708 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17709 replacing the pWIDE etc. symbols removed from editfns.c.
17711 * keyboard.h (num_input_events): Now uintmax_t.
17712 This is (very slightly) less likely to mess up due to wraparound.
17715 * buffer.c: Integer signedness fixes.
17716 (alloc_buffer_text, enlarge_buffer_text):
17717 Use ptrdiff_t rather than size_t when either will do, as we prefer
17720 * alloc.c: Integer signedness and overflow fixes.
17721 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17722 (__malloc_size_t): Default to size_t, not to int.
17723 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17724 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17725 Prefer ptrdiff_t to size_t when either would do, as we prefer
17727 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17728 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17729 Now const. Initialize with values that are in range even if char
17731 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17732 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17733 These functions do the right thing with sizes > 2**32.
17734 (check_depth): Now ptrdiff_t, not int.
17735 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17736 Adjust to new way of storing sizes. Check for size overflow bugs
17738 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17739 slightly wrong anyway, as it missed one instance of
17740 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17741 (refill_memory_reserve): Omit needless cast to size_t.
17742 (mark_object_loop_halt): Mark as externally visible.
17744 * xselect.c: Integer signedness and overflow fixes.
17745 (Fx_register_dnd_atom, x_handle_dnd_message):
17746 Use ptrdiff_t, not size_t, since we prefer signed.
17747 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17748 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17749 x_dnd_atoms_size and x_dnd_atoms_length.
17751 * doprnt.c: Prefer signed to unsigned when either works.
17753 * doprnt.c (doprnt):
17755 * xdisp.c (vmessage):
17756 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17757 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17758 prefer signed arithmetic to avoid comparison confusion.
17759 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17760 but is a bit tricky.
17762 Assume freestanding C89 headers, string.h, stdlib.h.
17763 * data.c, doprnt.c, floatfns.c, print.c:
17764 Include float.h unconditionally.
17765 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17766 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17767 * regex.c: Likewise for stddef.h, string.h.
17768 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17769 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17770 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17771 (STDC_HEADERS): Remove obsolete defines.
17772 * sysdep.c: Include limits.h unconditionally.
17774 Assume support for memcmp, memcpy, memmove, memset.
17775 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17776 * regex.c (memcmp, memcpy):
17777 Remove; we assume C89 now.
17779 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17780 (__malloc_safe_bcopy): Remove; no longer needed.
17782 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17783 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17784 well either way, and we prefer signed to unsigned.
17786 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17788 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17789 closes the connection while we're reading (bug#9182).
17791 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17793 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17794 are specified (Bug#9168).
17796 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17798 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17799 Found by GCC static checking and --with-wide-int on a 32-bit host.
17801 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17803 * xdisp.c (compute_display_string_pos): Fix logic of caching
17804 previous display string position. Initialize cached_prev_pos to
17805 -1. Fixes slow-down at the beginning of a buffer.
17807 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17809 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17810 for attrs[LFACE_FONTSET_INDEX].
17812 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17814 * xml.c (parse_region): Remove unused local
17815 that was recently introduced.
17817 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17819 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17820 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17822 * xdisp.c (move_it_in_display_line_to): Record the best matching
17823 position for TO_CHARPOS while scanning the line, and restore it on
17824 exit if none of the characters scanned was an exact match.
17825 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17826 when exact match is impossible due to invisible text, and the
17827 lines are truncated.
17829 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17831 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17834 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17836 Fix a significant slow-down of cursor motion with C-n, C-p,
17837 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17838 auto-repeat under bidi redisplay in fontified buffers.
17839 * xdisp.c (compute_stop_pos_backwards): New function.
17840 (next_element_from_buffer): Call compute_stop_pos_backwards to
17841 find a suitable prev_stop when we find ourselves before
17843 (reseat): Don't look for prev_stop, as that could mean a very long
17845 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17846 <cached_disp_overlay_modiff>: Cache for last found display string
17848 (compute_display_string_pos): Return the cached position if asked
17849 about the same buffer in the same area of character positions, and
17850 the buffer wasn't changed since the time the display string
17851 position was cached.
17853 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17855 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17856 is an integer, which is important for empty lines. (Bug#9149)
17858 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17860 * frame.c (Fmodify_frame_parameters): In tty case, update the
17861 default face if necessary (Bug#4238).
17863 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17865 * editfns.c (Fstring_to_char): No need to explain what a character
17866 is in the docstring (Bug#6576).
17868 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17870 * xml.c (parse_region): Make sure we always return a tree.
17872 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17874 * xml.c (parse_region): If a document contains only comments,
17877 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17879 * xml.c (make_dom): Return comments, too.
17881 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17884 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17885 and the surrounding thread.
17886 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17887 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17888 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17890 * s/openbsd.h (BROKEN_SIGIO): Define.
17891 * unexelf.c (unexec) [__OpenBSD__]:
17892 Don't update the .mdebug section of the Alpha COFF symbol table.
17894 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17896 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17899 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17901 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17902 This fixes some race conditions on the permissions of any newly
17905 * alloc.c (valid_pointer_p): Use pipe, not open.
17906 This fixes some permissions issues when debugging.
17908 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17909 If fchown fails to set both uid and gid, try to set just gid,
17910 as that is sometimes allowed. Adjust the file's mode to eliminate
17911 setuid or setgid bits that are inappropriate if fchown fails.
17913 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17915 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17916 to compare Lisp_Objects.

17921 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17923 * lread.c (read_integer): Unread even EOF character.
17924 (read1): Likewise. Properly record start position of symbol.
17926 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17927 symbol character follows.
17929 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17931 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17932 This works around a problem with the previous change to Fcopy_file.
17933 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17934 and without this change, GCC might complain about discarding
17935 fchown's return value.
17937 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17939 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17941 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17943 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17945 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17947 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17948 it's used from the C level.
17950 * process.c: Use the same condition for POLL_FOR_INPUT in both
17951 keyboard.c and process.c (bug#1858).
17953 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17955 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17956 (Fgnutls_boot): Use it.
17958 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17960 * doc.c (Fsubstitute_command_keys): Revert last change.
17962 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17964 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17965 quotes the next character, and doesn't affect other longer
17966 sequences (bug#8935).
17968 * lread.c (syms_of_lread): Clarify that is isn't only
17969 `eval-buffer' and `eval-defun' that's affected by
17970 `lexical-binding' (bug#8460).
17972 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17974 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17975 bidi redisplay when a line includes both an image and is truncated.
17977 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17979 Fix minor problems found by static checking.
17980 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17981 (elsz): Now a signed constant, not a size_t var. We prefer signed
17982 types to unsigned, to avoid integer comparison confusion. Without
17983 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17984 "cannot optimize loop, the loop counter may overflow", a symptom
17986 * indent.c (Fvertical_motion): Mark locals as initialized.
17987 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17989 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17991 * search.c (Fre_search_backward): Mention `case-fold-search' in
17992 all the re_search_* functions (bug#8138).

18012 buffer position was specified. Initialize paragraph_embedding to
18014 (reseat_to_string): Initialize the bidi iterator.
18015 (display_string): If we need to ignore text properties of
18016 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
18017 original value of -1 will not work with bidi.)
18018 (compute_display_string_pos): First arg is now struct
18019 `text_pos *'; all callers changed. Support display properties on
18021 (compute_display_string_end): Support display properties on Lisp
18023 (init_iterator, reseat_1, reseat_to_string): Initialize the
18024 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
18025 when iterating on a string not from display properties).
18026 (compute_display_string_pos, compute_display_string_end):
18027 Fix calculation of the object to scan. Fixes an error when using
18029 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
18030 base_level_stop; instead, set base_level_stop to BEGV.
18031 Fixes crashes in vertical-motion.
18032 (next_element_from_buffer): Improve commentary for when
18033 the iterator is before prev_stop.
18034 (init_iterator): Initialize bidi_p from the default value of
18035 bidi-display-reordering, not from buffer-local value. Use the
18036 buffer-local value only if initializing for buffer iteration.
18037 (handle_invisible_prop): Support invisible properties on strings
18038 that are being bidi-reordered.
18039 (set_iterator_to_next): Support bidi reordering of C strings and

18045 Use IT_STRING_CHARPOS when displaying from a Lisp string.
18046 (init_iterator): Don't initialize it->bidi_p for strings
18048 (reseat_to_string): Initialize it->bidi_p for strings here.

18056 (get_visually_first_element): New function, refactored from common
18057 parts of next_element_from_buffer, next_element_from_string, and
18058 next_element_from_c_string.
18059 (tool_bar_lines_needed, redisplay_tool_bar)
18060 (display_menu_bar): Force left-to-right direction. Add a FIXME
18061 comment for making that be controlled by a user option.
18062 (push_it, pop_it): Save and restore the state of the
18063 bidi iterator. Save and restore the bidi_p flag.
18064 (pop_it): Iterate out of display property for string iteration as

18070 (get_overlay_strings_1, push_display_prop): Set up the bidi
18071 iterator for displaying display or overlay strings.
18072 (forward_to_next_line_start): Don't use the shortcut if
18074 (back_to_previous_visible_line_start): If handle_display_prop
18075 pushed the iterator stack, restore the internal state of the bidi
18076 iterator by calling bidi_pop_it same number of times.
18077 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
18078 and we are bidi-iterating, don't decrement the iterator position;
18079 instead, set the first_elt flag in the bidi iterator, to produce
18081 (reseat_1): Remove redundant setting of string_from_display_prop_p.
18082 (push_display_prop): xassert that we are iterating a buffer.
18083 (push_it, pop_it): Save and restore paragraph_embedding member.
18084 (handle_single_display_spec, next_overlay_string)
18085 (get_overlay_strings_1, reseat_1, reseat_to_string)
18086 (push_display_prop): Set up the `unibyte' member of bidi_it.string
18087 correctly. Don't assume unibyte strings are not bidi-reordered.
18088 (compute_display_string_pos)
18089 (compute_display_string_end): Fix handling the case of C string.
18090 (push_it, pop_it): Save and restore from_disp_prop_p.

18096 property. Fix a typo in popping stretch info. Add an assertion
18097 for verifying that the iterator position is in sync with the bidi
18099 (handle_single_display_spec, get_overlay_strings_1)

18124 displayed in margins. (Bug#8133) (Bug#8867)
18125 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
18127 (pos_visible_p): Support positions in bidi-reordered lines.
18128 Save and restore bidi cache.
18130 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

18149 Support iteration over a string.
18150 (bidi_set_sor_type, bidi_resolve_explicit_1)
18151 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
18152 can now be zero (for strings); special values 0 and -1 were
18153 changed to -1 and -2, respectively.
18154 (bidi_char_at_pos): New function.
18155 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

18241 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
18243 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
18244 The old code sometimes used this field without initializing it.
18246 * alloc.c (gc_sweep): Don't read past end of array.
18247 In theory, the old code could also have corrupted Emacs internals,
18248 though it'd be very unlikely.

18511 (clone_per_buffer_values): Don't assume that

18513 This isn't true in general, and it's particularly not true
18514 if Emacs is configured with --with-wide-int.
18515 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

18552 Random fixes. E.g., (random) never returned negative values.
18553 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18554 subseconds part to the entropy, as that's a bit more random.
18555 Prefer signed to unsigned, since the signedness doesn't matter and
18556 in general we prefer signed. When given a limit, use a
18557 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18558 latter isn't right if USE_2_TAGS_FOR_INTS.
18559 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18560 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18572 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18573 This is more efficient than Ffile_directory_p and avoids a minor race.
18575 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18577 * buffer.c (Foverlay_put): Say what the return value is
18580 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18581 is a directory before asking whether to use the file name

18584 error be more correct.
18586 * fns.c (Frequire): Remove the mention of the .gz files, since
18587 that's installation-specific, but keep the mention of

18600 Qgnutls_bootprop_verify_error (which is no longer used).
18602 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18603 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18604 Also (re)move comments that are misplaced or no longer relevant.

18633 * lread.c (syms_of_lread): Mention single symbols defined by
18634 `defvar' or `defconst' (bug#7154).
18636 * fns.c (Frequire): Mention .el.gz files (bug#7314).
18637 (Frequire): Mention get-load-suffixes.

18667 (syms_of_keymap): Defsubr make-composed-keymap.
18668 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
18669 (parse_menu_item): Trivial simplification.
18671 2011-07-01 Glenn Morris <rgm@gnu.org>
18673 * Makefile.in (SETTINGS_LIBS): Fix typo.
18675 2011-07-01 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny change)

18705 * eval.c (struct backtrace): Simplify and port the data structure.
18706 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18707 signed bit field, as this assumption is not portable and it makes
18708 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18709 "char debug_on_exit : 1" as this is not portable either; instead,
18710 use the portable "unsigned int debug_on_exit : 1". Remove unused
18711 member evalargs. Remove obsolete comments about cc bombing out.
18713 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

18781 (emacs_fixed_new): Set priv->f to argument.
18782 (emacs_fixed_get_preferred_width)
18783 (emacs_fixed_get_preferred_height): Use min_width/height from
18784 frames size_hint to set minimum and natural (Bug#8919).
18785 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18786 and use min_width/height from frames size_hint to set
18787 min_width/height (Bug#8919).
18789 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.

18807 Use gnulib's dup2 module instead of rolling our own.
18808 * sysdep.c (dup2) [!HAVE_DUP2]: Remove; gnulib now does this.

18875 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
18877 Integer and buffer overflow fixes (Bug#8873).
18879 * print.c (printchar, strout): Check for string overflow.
18880 (PRINTPREPARE, printchar, strout):
18881 Don't set size unless allocation succeeds.
18883 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18884 for sizes. Check for string overflow more accurately.
18885 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
18887 * macros.c: Integer and buffer overflow fixes.
18888 * keyboard.h (struct keyboard.kbd_macro_bufsize):
18889 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

18893 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
18895 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
18897 * lread.c: Integer overflow fixes.
18898 (read_integer): Radix is now EMACS_INT, not int,
18899 to improve quality of diagnostics for out-of-range radices.
18900 Calculate buffer size correctly for out-of-range radices.
18901 (read1): Check for integer overflow in radices, and in
18902 read-circle numbers.
18903 (read_escape): Avoid int overflow.
18904 (Fload, openp, read_buffer_size, read1)
18905 (substitute_object_recurse, read_vector, read_list, map_obarray):
18906 Use ptrdiff_t, not int, for sizes.

18921 2011-06-22 Leo Liu <sdl.web@gmail.com>
18923 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
18924 Move to minibuffer.el.
18926 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18928 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
18929 The following patches are for when GLYPH_DEBUG && !XASSERT.
18930 * dispextern.h (trace_redisplay_p, dump_glyph_string):
18931 * dispnew.c (flush_stdout):
18932 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
18933 Mark as externally visible.
18934 * dispnew.c (check_window_matrix_pointers): Now static.
18935 * dispnew.c (window_to_frame_vpos):
18936 * xfns.c (unwind_create_frame):
18937 * xterm.c (x_check_font): Remove unused local.
18938 * scroll.c (CHECK_BOUNDS):
18939 * xfaces.c (cache_fache): Rename local to avoid shadowing.
18940 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
18941 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
18942 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
18943 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
18945 (debug_method_add): Use va_list and vsprintf rather than relying
18946 on undefined behavior with wrong number of arguments.
18947 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18948 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18949 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18950 since we're not interested in debugging glyphs with old libraries.
18951 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18952 GCC 4.6.0's static checking.
18954 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
18956 Integer overflow and signedness fixes (Bug#8873).
18957 A few related buffer overrun fixes, too.

18965 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
18966 (x_create_bitmap_from_xpm_data):
18967 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
18968 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
18970 * xfaces.c (load_pixmap):
18971 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
18972 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
18973 (.bitmaps_last, struct x_output.icon_bitmap):
18974 Use ptrdiff_t, not int, for bitmap indexes.
18975 (x_allocate_bitmap_record): Check for size overflow.
18976 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
18978 Use ptrdiff_t, not int, for overlay counts.
18979 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
18980 * editfns.c (overlays_around, get_pos_property):
18981 * textprop.c (get_char_property_and_overlay):
18982 * xdisp.c (next_overlay_change, note_mouse_highlight):
18983 * xfaces.c (face_at_buffer_position):
18984 * buffer.c (OVERLAY_COUNT_MAX): New macro.
18985 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
18986 (Fnext_overlay_change, Fprevious_overlay_change)
18987 (mouse_face_overlay_overlaps, Foverlays_in):
18988 Use ptrdiff_t, not int, for sizes.
18989 (overlays_at, overlays_in): Check for size-calculation overflow.
18991 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
18993 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18994 (x_session_initialize): Do not assume string length fits in int.
18996 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
18997 This is unlikely, but can occur if DPI is outlandish.
18999 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
19000 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
19002 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
19003 * xrdb.c (magic_file_p, search_magic_path):
19004 Omit last arg SUFFIX; it was always 0. All callers changed.
19005 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
19007 * xfont.c (xfont_match): Avoid need for strlen.
19009 * xfns.c: Don't assume strlen fits in int.

19012 * xdisp.c (message_log_check_duplicate): Return intmax_t,
19013 not unsigned long, as we prefer signed integers. All callers changed.
19014 Detect integer overflow in repeat count.
19015 (message_dolog): Don't assume print length fits in 39 bytes.
19016 (display_mode_element): Don't assume strlen fits in int.
19018 * termcap.c: Don't assume sizes fit in int and never overflow.
19019 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
19020 (gobble_line): Check for size-calculation overflow.
19022 * minibuf.c (Fread_buffer):
19023 * lread.c (intern, intern_c_string):
19024 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
19025 Don't assume string length fits in int.
19027 * keyboard.c (parse_tool_bar_item):
19028 * gtkutil.c (style_changed_cb): Avoid need for strlen.
19030 * font.c: Don't assume string length fits in int.

19033 (font_intern_prop): Don't assume string length fits in int.
19034 Don't assume integer property fits in fixnum.
19035 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
19037 * filelock.c: Fix some buffer overrun and integer overflow issues.
19038 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
19039 Reformulate so as not to need the command string.
19040 Invoke gzip -cd rather than gunzip, as it's more portable.
19041 (lock_info_type, lock_file_1, lock_file):
19042 Don't assume pid_t and time_t fit in unsigned long.
19043 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
19044 (current_lock_owner): Prefer signed type for sizes.
19045 Use memcpy, not strncpy, where memcpy is what is really wanted.
19046 Don't assume (via atoi) that time_t and pid_t fit in int.
19047 Check for time_t and/or pid_t out of range, e.g., via a network share.
19048 Don't alloca where an auto var works fine.
19050 * fileio.c: Fix some integer overflow issues.
19051 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
19052 Don't assume string length fits in int.
19053 (directory_file_name): Don't assume string length fits in long.
19054 (make_temp_name): Don't assume pid fits in int, or that its print
19055 length is less than 20.
19057 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
19059 * coding.c (make_subsidiaries): Don't assume string length fits in int.
19061 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
19063 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
19064 We prefer signed integers, even for size calculations.
19066 * emacs.c: Don't assume string length fits in 'int'.
19067 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
19068 (main): Don't invoke strlen when not needed.
19070 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.

19073 * callproc.c (getenv_internal_1, getenv_internal)
19074 (Fgetenv_internal):
19075 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
19077 * lread.c (invalid_syntax): Omit length argument.
19078 All uses changed. This doesn't fix a bug, but it simplifies the
19079 code away from its former Hollerith-constant appearance, and it's
19080 one less 'int' to worry about when looking at integer-overflow issues.
19081 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
19083 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
19084 This didn't break anything, but it didn't help either.
19085 It's confusing to put a bogus integer in a place where the actual
19086 value does not matter.
19087 (LIST_END_P): Remove unused macro and its bogus comment.
19088 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
19090 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
19091 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
19093 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
19094 We prefer signed types, and the value cannot exceed the EMACS_INT
19095 range anyway (because otherwise the length would not be representable).
19096 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
19097 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
19098 This avoids a GCC warning when WIDE_EMACS_INT.
19100 * indent.c (sane_tab_width): New function.
19101 (current_column, scan_for_column, Findent_to, position_indentation)
19102 (compute_motion): Use it. This is just for clarity.
19103 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
19105 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
19107 * lisp.h (lint_assume): New macro.
19108 * composite.c (composition_gstring_put_cache):
19109 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
19111 * editfns.c, insdel.c:
19112 Omit unnecessary forward decls, to simplify future changes.
19114 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
19116 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
19118 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
19119 Use much-faster test for byte-length change.
19120 Don't assume string byte-length fits in 'int'.
19121 Check that character arg fits in 'int'.
19122 (mapcar1): Declare byte as byte, for clarity.
19124 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
19126 * fns.c (concat): Catch string overflow earlier.
19127 Do not rely on integer wraparound.
19129 * dispextern.h (struct it.overlay_strings_charpos)
19130 (struct it.selective): Now EMACS_INT, not int.
19131 * xdisp.c (forward_to_next_line_start)
19132 (back_to_previous_visible_line_start)
19133 (reseat_at_next_visible_line_start, next_element_from_buffer):
19134 Don't arbitrarily truncate the value of 'selective' to int.
19136 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
19138 * composite.c: Don't truncate sizes to 'int'.
19139 (composition_gstring_p, composition_reseat_it)
19140 (composition_adjust_point): Use EMACS_INT, not int.
19141 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
19142 not EMACS_UINT, for indexes.
19144 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
19146 * buffer.c: Include <verify.h>.
19147 (struct sortvec.priority, struct sortstr.priority):
19148 Now EMACS_INT, not int.
19149 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
19150 (struct sortstr.size, record_overlay_string)
19151 (struct sortstrlist.size, struct sortlist.used):
19152 Don't truncate size to int.
19153 (record_overlay_string): Check for size-calculation overflow.
19154 (init_buffer_once): Check at compile-time, not run-time.
19156 2011-06-22 Jim Meyering <meyering@redhat.com>
19158 Don't leak an XBM-image-sized buffer
19159 * image.c (xbm_load): Free the image buffer after using it.
19161 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
19164 * composite.c (find_automatic_composition): Omit needless 'return 0;'
19165 that Sun C diagnosed.
19166 * fns.c (secure_hash): Fix pointer signedness issue.
19167 * intervals.c (static_offset_intervals): New function.
19168 (offset_intervals): Use it.
19170 2011-06-21 Leo Liu <sdl.web@gmail.com>
19173 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
19176 * fns.c (secure_hash): Rename from crypto_hash_function and change
19177 the first arg to accept symbols.
19178 (Fsecure_hash): New primitive.
19179 (syms_of_fns): New symbols.
19181 2011-06-20 Deniz Dogan <deniz@dogan.se>
19183 * process.c (Fset_process_buffer): Clarify return value in
19186 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
19188 * dispnew.c (add_window_display_history): Use BVAR.
19190 * xdisp.c (debug_method_add): Use BVAR.
19191 (check_window_end, dump_glyph_matrix, dump_glyph)
19192 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
19194 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
19197 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
19198 check till after the cache is created in init_frame_faces.
19200 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
19202 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
19204 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
19206 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
19207 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
19208 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
19210 Improve buffer-overflow checking (Bug#8873).
19211 * fileio.c (Finsert_file_contents):
19212 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
19213 Remove the old (too-loose) buffer overflow checks.
19214 They weren't needed, since make_gap checks for buffer overflow.
19215 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
19216 The old code merely checked for Emacs fixnum overflow, and relied
19217 on undefined (wraparound) behavior. The new code avoids undefined
19218 behavior, and also checks for ptrdiff_t and/or size_t overflow.
19220 * editfns.c (Finsert_char): Don't dump core with very negative counts.
19221 Tune. Don't use wider integers than needed. Don't use alloca.
19222 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
19224 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
19226 * insdel.c, lisp.h (buffer_overflow): New function.
19227 (insert_from_buffer_1, replace_range, replace_range_2):
19228 * insdel.c (make_gap_larger):
19229 * editfns.c (Finsert_char):
19230 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
19232 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
19234 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
19236 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
19238 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
19239 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
19241 * fileio.c: Don't assume EMACS_INT fits in off_t.
19242 (emacs_lseek): New static function.
19243 (Finsert_file_contents, Fwrite_region): Use it.
19244 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
19246 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
19248 * fns.c: Don't overflow int when computing a list length.
19249 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
19250 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
19251 truncation on 64-bit hosts. Check for QUIT every
19252 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
19253 faster and is responsive enough.
19254 (Flength): Report an error instead of overflowing an integer.
19255 (Fsafe_length): Return a float if the value is not representable
19256 as a fixnum. This shouldn't happen except in contrived situations.
19257 (Fnthcdr, Fsort): Don't assume list length fits in int.
19258 (Fcopy_sequence): Don't assume vector length fits in int.
19260 * alloc.c: Check that resized vectors' lengths fit in fixnums.
19261 (header_size, word_size): New constants.
19262 (allocate_vectorlike): Don't check size overflow here.
19263 (allocate_vector): Check it here instead, since this is the only
19264 caller of allocate_vectorlike that could cause overflow.
19265 Check that the new vector's length is representable as a fixnum.
19267 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
19268 The previous code was bogus. For example, next_almost_prime (32)
19269 returned 39, which is undesirable as it is a multiple of 3; and
19270 next_almost_prime (24) returned 25, which is a multiple of 5 so
19271 why was the code bothering to check for multiples of 7?
19273 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
19275 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
19277 Variadic C functions now count arguments with ptrdiff_t.
19278 This partly undoes my 2011-03-30 change, which replaced int with size_t.
19279 Back then I didn't know that the Emacs coding style prefers signed int.
19280 Also, in the meantime I found a few more instances where arguments
19281 were being counted with int, which may truncate counts on 64-bit
19282 machines, or EMACS_INT, which may be unnecessarily wide.
19283 * lisp.h (struct Lisp_Subr.function.aMANY)
19284 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
19285 Arg counts are now ptrdiff_t, not size_t.
19286 All variadic functions and their callers changed accordingly.
19287 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
19288 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
19289 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
19290 * callint.c (Fcall_interactively): Check arg count for overflow,
19291 to avoid potential buffer overrun. Use signed char, not 'int',
19292 for 'varies' array, so that we needn't bother to check its size
19293 calculation for overflow.
19294 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
19295 * eval.c (apply_lambda):
19296 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
19297 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
19298 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
19300 * callint.c (Fcall_interactively): Don't use index var as event count.
19302 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
19303 * mem-limits.h (SIZE): Remove; no longer used.
19305 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
19307 Remove unnecessary casts.
19308 * xterm.c (x_term_init):
19309 * xfns.c (x_set_border_pixel):
19310 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
19311 These aren't needed now that we assume ANSI C.
19313 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
19314 It's more likely to cause problems (due to unsigned overflow)
19317 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
19319 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
19321 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
19323 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
19325 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
19327 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
19329 GLYPH_CODE_FACE returns EMACS_INT, not int.
19330 * dispextern.h (merge_faces):
19331 * xfaces.c (merge_faces):
19332 * xdisp.c (get_next_display_element, next_element_from_display_vector):
19333 Don't assume EMACS_INT fits in int.
19335 * character.h (CHAR_VALID_P): Remove unused parameter.
19336 * fontset.c, lisp.h, xdisp.c: All uses changed.
19338 * editfns.c (Ftranslate_region_internal): Omit redundant test.
19340 * fns.c (concat): Minor tuning based on overflow analysis.
19341 This doesn't fix any bugs. Use int to hold character, instead
19342 of constantly refetching from Emacs object. Use XFASTINT, not
19343 XINT, for value known to be a character. Don't bother comparing
19344 a single byte to 0400, as it's always less.
19346 * floatfns.c (Fexpt):
19347 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
19349 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
19352 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
19354 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
19355 Without this fix, on a 64-bit host (aset S 0 4294967386) would
19356 incorrectly succeed when S was a string, because 4294967386 was
19357 truncated before it was used.
19359 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
19360 Otherwise, an out-of-range integer could cause undefined behavior
19363 * composite.c: Use int, not EMACS_INT, for characters.
19364 (fill_gstring_body, composition_compute_stop_pos): Use int, not
19365 EMACS_INT, for values that are known to be in character range.
19366 This doesn't fix any bugs but is the usual style inside Emacs and
19367 may generate better code on 32-bit machines.
19369 Make sure a 64-bit char is never passed to ENCODE_CHAR.
19370 This is for reasons similar to the recent CHAR_STRING fix.
19371 * charset.c (Fencode_char): Check that character arg is actually
19372 a character. Pass an int to ENCODE_CHAR.
19373 * charset.h (ENCODE_CHAR): Verify that the character argument is no
19374 wider than 'int', as a compile-time check to prevent future regressions
19377 * character.c (char_string): Remove unnecessary casts.
19379 Make sure a 64-bit char is never passed to CHAR_STRING.
19380 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
19381 by silently ignoring the top 32 bits, allowing some values
19382 that were far too large to be valid characters.
19383 * character.h: Include <verify.h>.
19384 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
19385 arguments are no wider than unsigned, as a compile-time check
19386 to prevent future regressions in this area.
19388 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
19389 (Fsubst_char_in_region):
19391 * xdisp.c (decode_mode_spec_coding):
19392 Adjust to CHAR_STRING's new requirement.
19393 * editfns.c (Finsert_char, Fsubst_char_in_region):
19394 * fns.c (concat): Check that character args are actually
19395 characters. Without this test, these functions did the wrong
19396 thing with wildly out-of-range values on 64-bit hosts.
19398 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19399 These casts should not be needed on 32-bit hosts, either.
19400 * keyboard.c (read_char):
19401 * lread.c (Fload): Remove casts to unsigned.
19403 * lisp.h (UNSIGNED_CMP): New macro.
19404 This fixes comparison bugs on 64-bit hosts.
19405 (ASCII_CHAR_P): Use it.
19406 * casefiddle.c (casify_object):
19407 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19408 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19409 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19410 * dispextern.h (FACE_FROM_ID):
19411 * keyboard.c (read_char): Use UNSIGNED_CMP.
19413 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19414 not to EMACS_INT, to avoid GCC warning.
19416 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19418 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19419 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19420 isn't needed on 32-bit machines.
19422 * buffer.c (Fgenerate_new_buffer_name):
19423 Use EMACS_INT for count, not int.
19424 (advance_to_char_boundary): Return EMACS_INT, not int.
19426 * data.c (Qcompiled_function): Now static.
19428 * window.c (window_body_lines): Now static.
19430 * image.c (gif_load): Rename local to avoid shadowing.
19432 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19433 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19434 * alloc.c (make_save_value): Integer argument is now of type
19435 ptrdiff_t, not int.
19436 (mark_object): Use ptrdiff_t, not int.
19437 * lisp.h (pD): New macro.
19438 * print.c (print_object): Use it.
19440 * alloc.c: Use EMACS_INT, not int, to count objects.
19441 (total_conses, total_markers, total_symbols, total_vector_size)
19442 (total_free_conses, total_free_markers, total_free_symbols)
19443 (total_free_floats, total_floats, total_free_intervals)
19444 (total_intervals, total_strings, total_free_strings):
19445 Now EMACS_INT, not int. All uses changed.
19446 (Fgarbage_collect): Compute overall total using a double, so that
19447 integer overflow is less likely to be a problem. Check for overflow
19448 when converting back to an integer.
19449 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19450 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19451 These were 'int' variables that could overflow on 64-bit hosts;
19452 they were never used, so remove them instead of repairing them.
19453 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19454 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19455 Previously, this ceilinged at INT_MAX, but that doesn't work on
19457 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19459 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19460 (allocate_vectorlike): Check for ptrdiff_t overflow.
19461 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19462 when a (possibly-narrower) signed value would do just as well.
19463 We prefer using signed arithmetic, to avoid comparison confusion.
19465 * alloc.c: Catch some string size overflows that we were missing.
19466 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19467 for convenience in STRING_BYTES_MAX.
19468 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19469 The definition here is exact; the one in lisp.h was approximate.
19470 (allocate_string_data): Check for string overflow. This catches
19471 some instances we weren't catching before. Also, it catches
19472 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19473 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19474 and ptrdiff_t and EMACS_INT are both 64 bits.
19476 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19477 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19478 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19480 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19482 * alloc.c (Fmake_string): Check for out-of-range init.
19484 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19486 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
19488 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
19490 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
19491 xg_get_default_scrollbar_width.
19493 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
19494 (int_gtk_range_get_value): Move to the scroll bar part of the file.
19495 (style_changed_cb): Call update_theme_scrollbar_width and call
19496 x_set_scroll_bar_default_width and xg_frame_set_char_size for
19497 all frames (Bug#8505).
19498 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
19499 Call gtk_window_set_resizable if HAVE_GTK3.
19500 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
19501 and height if HAVE_GTK3 (Bug#8505).
19502 (scroll_bar_width_for_theme): New variable.
19503 (update_theme_scrollbar_width): New function.
19504 (xg_get_default_scrollbar_width): Move code to
19505 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
19506 (xg_initialize): Call update_theme_scrollbar_width.
19508 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
19510 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
19512 2011-06-12 Martin Rudalics <rudalics@gmx.at>
19514 * frame.c (make_frame): Call other_buffer_safely instead of
19517 * window.c (temp_output_buffer_show): Call display_buffer with
19518 second argument Vtemp_buffer_show_specifiers and reset latter
19519 immediately after the call.
19520 (Vtemp_buffer_show_specifiers): New variable.
19521 (auto_window_vscroll_p, next_screen_context_lines)
19522 (Vscroll_preserve_screen_position): Remove leading asterisks from
19525 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
19527 Fix minor problems found by GCC 4.6.0 static checking.
19528 * buffer.c (Qclone_number): Remove for now, as it's unused.
19529 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
19530 (record_buffer): Remove unused local.
19531 * frame.c (other_visible_frames, frame_buffer_list): Now static.
19532 (set_frame_buffer_list): Remove; unused.
19533 * frame.h (other_visible_frames): Remove decl.
19534 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
19535 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
19536 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
19538 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
19539 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):

20016 New error handlers.
20017 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
20018 Obey Vx_select_enable_clipboard_manager. Catch errors in
20019 x_clipboard_manager_save (Bug#8779).
20020 (Vx_select_enable_clipboard_manager): New variable.
20021 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
20023 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>

20027 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20029 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap
20030 in the current matrix if keep_current_p is non-zero.

20036 2011-06-03 Eli Zaretskii <eliz@gnu.org>
20038 Support bidi reordering of text covered by display properties.
20040 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
20041 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
20042 (bidi_cache_search, bidi_cache_iterator_state)
20043 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
20044 (bidi_level_of_next_char, bidi_move_to_visually_next):
20045 Support character positions inside a run of characters covered by a
20047 (bidi_paragraph_init, bidi_resolve_explicit_1)
20048 (bidi_level_of_next_char): Call bidi_fetch_char and
20049 bidi_fetch_char_advance instead of FETCH_CHAR and
20050 FETCH_CHAR_ADVANCE.

20052 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
20054 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
20055 instead of using explicit *_CHAR codes.
20056 (bidi_resolve_explicit, bidi_resolve_weak):
20057 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
20058 bidirectional text is supported only in multibyte buffers.
20059 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
20060 it to initialize the frame_window_p member of struct bidi_it.
20061 (bidi_cache_iterator_state, bidi_resolve_explicit_1)

20064 bidi_it->nchars is non-positive.
20065 (bidi_level_of_next_char): Don't try to lookup the cache for the
20066 next/previous character if nothing is cached there yet, or if we
20067 were just reseat()'ed to a new position.
20069 * xdisp.c (set_cursor_from_row): Set start and stop points
20070 according to the row's direction when priming the loop that looks
20071 for the glyph on which to display cursor.
20072 (single_display_spec_intangible_p): Function deleted.
20073 (display_prop_intangible_p): Reimplement to call
20074 handle_display_spec instead of single_display_spec_intangible_p.
20075 Accept 3 additional arguments needed by handle_display_spec.
20076 This fixes incorrect cursor motion across display property with complex
20077 values: lists, `(when COND...)' forms, etc.
20078 (single_display_spec_string_p): Support property values that are
20079 lists with the argument STRING its top-level element.
20080 (display_prop_string_p): Fix the condition for processing a
20081 property that is a list to be consistent with handle_display_spec.
20082 (handle_display_spec): New function, refactored from the
20083 last portion of handle_display_prop.
20084 (compute_display_string_pos): Accept additional argument
20085 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
20086 value of a `display' property is a "replacing spec".
20087 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
20088 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
20089 the display property, but just return a value indicating whether
20090 the display property will replace the characters it covers.
20091 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
20092 frame_window_p members of struct bidi_it.
20093 (compute_display_string_pos, compute_display_string_end):
20095 (push_it): Accept second argument POSITION, where pop_it should
20096 jump to continue iteration.
20097 (reseat_1): Initialize bidi_it.disp_pos.
20099 * keyboard.c (adjust_point_for_property): Adjust the call to
20100 display_prop_intangible_p to its new signature.
20102 * dispextern.h (struct bidi_it): New member frame_window_p.
20103 (bidi_init_it): Update prototypes.
20104 (display_prop_intangible_p): Update prototype.
20105 (compute_display_string_pos, compute_display_string_end):
20106 Declare prototypes.

20113 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
20114 * lisp.h: Change signatures accordingly.
20115 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
20116 All callers changed. (Bug#8762)
20118 * gnutls.c: Use Emacs's memory allocators.
20119 Without this change, the gnutls library would invoke malloc etc.
20120 directly, which causes problems on non-SYNC_INPUT hosts, and which
20121 runs afoul of improving memory_full behavior. (Bug#8761)
20122 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
20123 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
20124 xfree instead of the default malloc, realloc, free.
20125 (Fgnutls_boot): No need to check for memory allocation failure,
20126 since xmalloc does that for us.
20128 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
20129 * category.c (hash_get_category_set):
20130 * ccl.c (ccl_driver):
20131 * charset.c (Fdefine_charset_internal):

20141 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
20142 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
20143 (Fsxhash, Fgethash, Fputhash, Fmaphash):
20144 * image.c (make_image, search_image_cache, lookup_image)
20145 (xpm_put_color_table_h):
20146 * lisp.h (struct Lisp_Hash_Table):
20147 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
20148 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
20149 for hashes and hash indexes, instead of 'unsigned' and 'int'.
20150 * alloc.c (allocate_vectorlike):
20151 Check for overflow in vector size calculations.
20152 * ccl.c (ccl_driver):
20153 Check for overflow when converting EMACS_INT to int.
20154 * fns.c, image.c: Remove unnecessary static decls that would otherwise
20155 need to be updated by these changes.
20156 * fns.c (make_hash_table, maybe_resize_hash_table):
20157 Check for integer overflow with large hash tables.
20158 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
20159 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
20160 (SXHASH_REDUCE): New macro.
20161 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
20162 Use it instead of discarding useful hash info with large hash values.
20163 (sxhash_float): New function.
20164 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
20165 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
20166 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
20167 Rewrite to use FIXNUM_BITS, as this simplifies things.
20168 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
20169 Adjust signatures to match updated version of code.
20170 (consing_since_gc): Now EMACS_INT, since a single hash table can
20171 use more than INT_MAX bytes.
20173 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
20175 Make it possible to build with GCC-4.6+ -O2 -flto.
20177 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
20179 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
20181 * minibuf.c (get_minibuffer, read_minibuf_unwind):
20182 Call minibuffer-inactive-mode.
20184 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
20186 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
20187 Update dependencies.
20189 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20191 * data.c (init_data): Remove code for UTS, this system is not
20194 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20196 Don't force ./temacs to start in terminal mode.
20198 * frame.c (make_initial_frame): Initialize faces in all cases, not
20199 only when CANNOT_DUMP is defined.
20200 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
20202 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20204 * dispnew.c (add_window_display_history): Use const for the string
20205 pointer. Remove declaration, not needed.
20207 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20209 Use 'inline', not 'INLINE'.
20210 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
20211 * alloc.c, fontset.c (INLINE): Remove.
20212 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
20213 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
20214 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
20215 * gmalloc.c (register_heapinfo): Use inline unconditionally.
20216 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
20218 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
20220 Make it possible to run ./temacs.
20222 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
20223 syms_of_callproc does the same thing. Remove test for
20224 "initialized", do it in the caller.
20225 * emacs.c (main): Avoid calling set_initial_environment when dumping.
20227 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
20229 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
20230 (read_minibuf): Use get_minibuffer.
20231 (syms_of_minibuf): Use DEFSYM.
20232 (Qmetadata): New var.
20233 * data.c (Qbuffer): Don't make it static.
20234 (syms_of_data): Use DEFSYM.
20236 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
20238 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
20239 (CCL_CODE_MIN): New macro.
20241 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
20243 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
20245 * eval.c (Qdebug): Now static.
20246 * lisp.h (Qdebug): Remove decl. This reverts a part of the
20247 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
20248 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
20250 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20252 * image.c: Various fixes to ImageMagick code comments.
20253 (Fimagemagick_types): Doc fix.
20255 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
20257 Minor fixes prompted by GCC 4.6.0 warnings.
20259 * xselect.c (converted_selections, conversion_fail_tag): Now static.
20261 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
20262 (x_clipboard_manager_save_all): Move extern decl to ...
20263 * xterm.h: ... here, so that it can be checked for consistency.
20265 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
20267 * xselect.c (x_clipboard_manager_save_frame)
20268 (x_clipboard_manager_save_all): New functions.
20269 (Fx_clipboard_manager_save): Lisp function deleted.
20271 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
20272 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
20274 * xterm.h: Update prototype.
20276 2011-05-28 William Xu <william.xwl@gmail.com>
20278 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
20279 exiting (Bug#8239).
20281 2011-05-28 Jim Meyering <meyering@redhat.com>
20283 Avoid a sign-extension bug in crypto_hash_function.
20284 * fns.c (to_uchar): Define.
20285 (crypto_hash_function): Use it to convert some newly-signed
20286 variables to unsigned, to avoid sign-extension bugs. For example,
20287 without this change, (md5 "truc") would evaluate to
20288 45723a2aff78ff4fff7fff1114760e62 rather than the expected
20289 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
20290 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
20292 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20294 Integer overflow fixes.
20296 * dbusbind.c: Serial number integer overflow fixes.
20297 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
20298 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
20299 to hold a serial number that is too large for a fixnum.
20300 (Fdbus_method_return_internal, Fdbus_method_error_internal):
20301 Check for serial numbers out of range. Decode any serial number
20302 that was so large that it became a float. (Bug#8722)
20304 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
20305 (Fdbus_call_method, Fdbus_call_method_asynchronously):
20306 Use XFASTINT rather than XUINT when numbers are nonnegative.
20307 (xd_append_arg, Fdbus_method_return_internal):
20308 (Fdbus_method_error_internal): Likewise. Also, for unsigned
20309 arguments, check that Lisp number is nonnegative, rather than
20310 silently wrapping negative numbers around. (Bug#8722)
20311 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
20314 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
20316 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
20318 ccl: Add integer overflow checks.
20319 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
20320 (IN_INT_RANGE): New macros.
20321 (ccl_driver): Use them to check for integer overflow when
20322 decoding a CCL program. Many of the new checks are whether XINT (x)
20323 fits in int; it doesn't always, on 64-bit hosts. The new version
20324 doesn't catch all possible integer overflows, but it's an
20325 improvement. (Bug#8719)
20327 * alloc.c (make_event_array): Use XINT, not XUINT.
20328 There's no need for unsigned here.
20330 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
20331 This follows up to the 2011-05-06 change that substituted uintptr_t
20332 for EMACS_INT. This case wasn't caught back then.
20334 Rework Fformat to avoid integer overflow issues.
20335 * editfns.c: Include <float.h> unconditionally, as it's everywhere
20336 now (part of C89). Include <verify.h>.
20337 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
20338 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
20339 (Fformat): Avoid the prepass trying to compute sizes; it was only
20340 approximate and thus did not catch overflow reliably. Instead, walk
20341 through the format just once, formatting and computing sizes as we go,
20342 checking for integer overflow at every step, and allocating a larger
20343 buffer as needed. Keep track separately whether the format is
20344 multibyte. Keep only the most-recently calculated precision, rather
20345 than them all. Record whether each argument has been converted to
20346 string. Use EMACS_INT, not int, for byte and char and arg counts.
20347 Support field widths and precisions larger than INT_MAX. Avoid
20348 sprintf's undefined behavior with conversion specifications such as %#d
20349 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
20350 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
20351 formatting out-of-range floating point numbers with int
20352 formats. (Bug#8668)
20354 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
20356 * data.c: Avoid integer truncation in expressions involving floats.
20357 * data.c: Include <intprops.h>.
20358 (arith_driver): When there's an integer overflow in an expression
20359 involving floating point, convert the integers to floating point
20360 so that the resulting value does not suffer from catastrophic
20361 integer truncation. For example, on a 64-bit host (* 4
20362 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
20363 Do not rely on undefined behavior after integer overflow.
20365 merge count_size_as_multibyte, parse_str_to_multibyte
20366 * character.c, character.h (count_size_as_multibyte):
20367 Rename from parse_str_to_multibyte; all uses changed.
20368 Check for integer overflow.
20369 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
20370 since it's now a duplicate of the other. This is more of
20371 a character than a buffer op, so better that it's in character.c.
20372 * fns.c, print.c: Adjust to above changes.
20374 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
20376 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
20378 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
20380 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20381 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
20382 (x_clipboard_manager_save): Now static.
20383 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
20385 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
20386 (crypto_hash_function): Now static.
20387 Fix pointer signedness problems. Avoid unnecessary initializations.
20389 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
20391 * termhooks.h (Vselection_alist): Make it terminal-local.
20393 * terminal.c (create_terminal): Initialize it.
20395 * xselect.c: Support for clipboard managers.
20396 (Vselection_alist): Move to termhooks.h as terminal-local var.
20397 (LOCAL_SELECTION): New macro.
20398 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20399 (symbol_to_x_atom): Remove gratuitous arg.
20400 (x_handle_selection_request, lisp_data_to_selection_data)
20401 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20402 (x_own_selection, x_get_local_selection, x_convert_selection):
20403 New arg, specifying work frame. Use terminal-local Vselection_alist.
20404 (some_frame_on_display): Delete unused function.
20405 (Fx_own_selection_internal, Fx_get_selection_internal)
20406 (Fx_disown_selection_internal, Fx_selection_owner_p)
20407 (Fx_selection_exists_p): New optional frame arg.
20408 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20409 (x_handle_selection_clear): Don't treat other terminals with the
20410 same keyboard specially. Use the terminal-local Vselection_alist.
20411 (x_clear_frame_selections): Use Frun_hook_with_args.
20413 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20415 * xterm.h: Add support for those atoms.
20417 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20419 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20420 (converted_selections, conversion_fail_tag): New global variables.
20421 (x_selection_request_lisp_error): Free the above.
20422 (x_get_local_selection): Remove unnecessary code.
20423 (x_reply_selection_request): Args changed; handle arbitrary array
20424 of converted selections stored in converted_selections.
20425 Separate the XChangeProperty and SelectionNotify steps.
20426 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20427 (x_convert_selection): New function.
20428 (x_handle_selection_event): Simplify.
20429 (x_get_foreign_selection): Don't ignore incoming requests while
20430 waiting for an answer; this will fail when we implement
20431 SAVE_TARGETS, and seems unnecessary anyway.
20432 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20433 (Vx_sent_selection_functions): Doc fix.
20435 2011-05-26 Leo Liu <sdl.web@gmail.com>
20437 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20439 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20441 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20443 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20444 for fringe update if it has periodic bitmap.
20445 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20446 and fringe_bitmap_periodic_p.
20448 * fringe.c (get_fringe_bitmap_data): New function.
20449 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20450 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20451 row. Mark glyph row for fringe update if periodicity changed.
20453 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20454 for fringe update unless it has periodic bitmap.
20456 2011-05-25 Kenichi Handa <handa@m17n.org>
20458 * xdisp.c (get_next_display_element): Set correct it->face_id for
20459 a static composition.
20461 2011-05-24 Leo Liu <sdl.web@gmail.com>
20464 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20466 * fns.c (crypto_hash_function, Fsha1): New function.
20467 (Fmd5): Use crypto_hash_function.
20468 (syms_of_fns): Add Ssha1.
20470 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20472 * gnutls.c: Remove unused macros.
20473 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20474 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20475 Remove macros that are defined and never used.
20476 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20478 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20480 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20481 (Fx_get_selection_internal): Minor cleanup.
20482 (Fx_own_selection_internal): Rename arguments for consistency with
20485 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20487 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20489 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20491 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20493 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20495 * dispnew.c (scrolling_window): Don't exclude the case that the
20496 last enabled row in the desired matrix touches the bottom boundary.
20498 2011-05-21 Glenn Morris <rgm@gnu.org>
20500 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20501 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20502 and add some more files.
20504 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20506 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20507 report_file_error introduced by the change from 2011-05-07.
20509 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20511 * systime.h (Time): Define only if emacs is defined.
20512 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20513 where the include path doesn't have X11/X.h by default. See
20514 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20516 2011-05-20 Kenichi Handa <handa@m17n.org>
20518 * composite.c (find_automatic_composition): Fix previous change.
20520 2011-05-20 Glenn Morris <rgm@gnu.org>
20522 * lisp.mk: New file, split from Makefile.in.
20523 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20524 (shortlisp): Remove.
20525 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20527 2011-05-19 Glenn Morris <rgm@gnu.org>
20529 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20530 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20531 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20532 (lisp): Set the order to that of loadup.el.
20533 (shortlisp): Make it a copy of $lisp.
20534 (SOME_MACHINE_LISP): Remove.
20535 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20536 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20538 2011-05-18 Kenichi Handa <handa@m17n.org>
20540 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20541 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20542 (find_automatic_composition): Mostly rewrite for efficiency.
20544 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20546 * makefile.w32-in: Update dependencies.
20548 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20550 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20551 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20553 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20555 Fix some integer overflow issues, such as string length overflow.
20557 * insdel.c (count_size_as_multibyte): Check for string overflow.
20559 * character.c (lisp_string_width): Check for string overflow.
20560 Use EMACS_INT, not int, for string indexes and lengths; in
20561 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20562 the resulting string length overflows an EMACS_INT; instead,
20563 report a string overflow if no precision given. When checking for
20564 precision exhaustion, use a check that cannot possibly have
20565 integer overflow. (Bug#8675)
20566 * character.h (lisp_string_width): Adjust to new signature.
20568 * alloc.c (string_overflow): New function.
20569 (Fmake_string): Use it. This doesn't change behavior, but saves
20570 a few bytes and will simplify future changes.
20571 * character.c (string_escape_byte8): Likewise.
20572 * lisp.h (string_overflow): New decl.
20574 Fixups, following up to the user-interface timestamp change.
20575 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20576 for UI timestamps, instead of unsigned long.
20577 * msdos.c (mouse_get_pos): Likewise.
20578 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20579 * w32gui.h (Time): Define by including "systime.h" rather than by
20580 declaring it ourselves. (Bug#8664)
20582 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20583 * image.c (clear_image_cache): Likewise.
20585 * term.c (term_mouse_position): Don't assume time_t wraparound.
20587 Be more systematic about user-interface timestamps.
20588 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20589 and sometimes 'EMACS_UINT', to represent these timestamps.
20590 This change causes it to use 'Time' uniformly, as that's what X uses.
20591 This makes the code easier to follow, and makes it easier to catch
20592 integer overflow bugs such as Bug#8664.
20593 * frame.c (Fmouse_position, Fmouse_pixel_position):
20594 Use Time, not unsigned long, for user-interface timestamps.
20595 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20596 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20597 * keyboard.h (last_event_timestamp): Likewise.
20598 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20599 * menu.h (xmenu_show): Likewise.
20600 * term.c (term_mouse_position): Likewise.
20601 * termhooks.h (struct input_event.timestamp): Likewise.
20602 (struct terminal.mouse_position_hook): Likewise.
20603 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20604 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20605 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20606 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20607 what it was before.
20608 * menu.h, termhooks.h: Include "systime.h", for Time.
20610 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20611 Don't assume that the difference between two unsigned long values
20612 can fit into an integer. At this point, we know button_down_time
20613 <= event->timestamp, so the difference must be nonnegative, so
20614 there's no need to cast the result if double-click-time is
20615 nonnegative, as it should be; check that it's nonnegative, just in
20616 case. This bug is triggered when events are more than 2**31 ms
20617 apart (about 25 days). (Bug#8664)
20619 * xselect.c (last_event_timestamp): Remove duplicate decl.
20620 (x_own_selection): Remove needless cast to unsigned long.
20622 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20623 that always fit in int. Use a sentinel instead of a counter, to
20624 avoid a temp and to allay GCC's concerns about possible int overflow.
20625 * frame.h (struct frame): Use int for menu_bar_items_used
20626 instead of EMACS_INT, since it always fits in int.
20628 * menu.c (grow_menu_items): Check for int overflow.
20630 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20632 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20633 Before, the code was not consistent. These values cannot exceed
20634 2**31 - 1 so there's no need to make them unsigned.
20635 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20636 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20637 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20639 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20641 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20642 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20643 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20644 presumably because the widths might not match.
20646 * window.c (size_window): Avoid needless test at loop start.
20648 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20650 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20652 2011-05-12 Drew Adams <drew.adams@oracle.com>
20654 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20656 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20658 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20659 `width' to `bar_area_x' and `bar_area_width', respectively.
20660 (x_scroll_run): Take account of fringe background extension.
20662 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20663 Rename local vars `left' and `width' to `bar_area_x' and
20664 `bar_area_width', respectively.
20665 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20666 background extension.
20668 2011-05-10 Jim Meyering <meyering@redhat.com>
20670 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20672 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20674 * image.c (Finit_image_library): Return t for built-in image types,
20675 like pbm and xbm. (Bug#8640)
20677 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20679 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20681 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20683 * w32console.c (Fset_screen_color): Doc fix.
20684 (Fget_screen_color): New function.
20685 (syms_of_ntterm): Defsubr it.
20687 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20688 unlink the temporary file if Fcall_process didn't create it in the
20690 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20691 child process will be redirected to a file specified with `:file'.
20692 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20693 cue to call_process_cleanup not to close that handle.
20695 2011-05-07 Ben Key <bkey76@gmail.com>
20697 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20698 one of two shell specific rules, either bootstrap-temacs-CMD or
20699 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20700 to the previous implementation of the bootstrap-temacs rule.
20701 The bootstrap-temacs-CMD rule is similar to the previous
20702 implementation of the bootstrap-temacs rule except that it
20703 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20706 These changes, along with some changes to nt/configure.bat,
20707 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20708 earlier fix to add support for --cflags and --ldflags options
20709 that include quotes so that it works whether make uses cmd or
20712 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20714 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20715 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20717 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20718 a string. Handle both cases.
20719 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20720 (Fdbus_register_method): Use Qinvalid_function.
20722 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20724 * makefile.w32-in: Update dependencies.
20725 (LISP_H): Add inttypes.h and stdin.h.
20726 (PROCESS_H): Add unistd.h.
20728 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20730 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20731 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20733 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20735 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20737 * term.c (vfatal): Remove stray call to va_end.
20738 It's not needed and the C Standard doesn't allow it here anyway.
20740 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20741 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20743 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20746 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20748 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20750 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20752 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20754 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20756 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20757 * charset.c (Fdefine_charset_internal): Don't initialize
20758 charset.code_space[15]. The value was garbage, on hosts with
20759 32-bit int (Bug#8600).
20761 * lread.c (read_integer): Be more consistent with string-to-number.
20762 Use string_to_number to do the actual conversion; this avoids
20763 rounding errors and fixes some other screwups. Without this fix,
20764 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20765 (digit_to_number): Move earlier, for benefit of read_integer.
20766 Return -1 if the digit is out of range for the base, -2 if it is
20767 not a digit in any supported base. (Bug#8602)
20769 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20771 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20772 to match comment at start of function. This also removes a
20773 GCC warning about overflow in a 32+64-bit port.
20775 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20777 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20778 Reported by Stefan Monnier in
20779 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20780 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20781 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20783 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20784 (EMACS_UINTPTR): Likewise, with uintptr_t.
20786 * lisp.h: Prefer 64-bit EMACS_INT if available.
20787 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20788 on 32-bit hosts that have 64-bit int, so that they can access
20790 However, temporarily disable this change unless the temporary
20791 symbol WIDE_EMACS_INT is defined.
20793 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20795 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20796 This removes an assumption that EMACS_INT and long are the same
20797 width as pointers. The assumption is true for Emacs porting targets
20798 now, but we want to make other targets possible.
20799 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20800 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20801 In the rest of the code, change types of integers that hold casted
20802 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20803 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20804 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20805 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20806 No need to cast type when ORing.
20807 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20808 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20809 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20810 assume EMACS_INT is the same width as char *.
20811 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20812 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20813 Remove no-longer-needed casts.
20814 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20815 (xg_tool_bar_help_callback, xg_make_tool_item):
20816 Use EMACS_INTPTR to hold an integer
20817 that will be cast to void *; this can avoid a GCC warning
20818 if EMACS_INT is not the same width as void *.
20819 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20820 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20821 (current_message_1, set_message_1):
20822 Use a local to convert to proper width without a cast.
20823 * xmenu.c (dialog_selection_callback): Likewise.
20825 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20826 Also, don't assume VALBITS / RAND_BITS is less than 5,
20827 and don't rely on undefined behavior when shifting a 1 left into
20829 * lisp.h (get_random): Change signature to match.
20831 * lread.c (hash_string): Use size_t, not int, for hash computation.
20832 Normally we prefer signed values; but hashing is special, because
20833 it's better to use unsigned division on hash table sizes so that
20834 the remainder is nonnegative. Also, size_t is the natural width
20835 for hashing into memory. The previous code used 'int', which doesn't
20836 retain enough info to hash well into very large tables.
20837 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20839 * dbusbind.c: Don't possibly lose pointer info when converting.
20840 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20841 Use XPNTR rather than XHASH, so that the high-order bits of
20842 the pointer aren't lost when converting through void *.

20929 * process.c: Include lisp.h before w32.h, not after.
20930 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20931 instead of gnutls_record_check_pending.

20935 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20937 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options

20986 inttypes.h, as a gnulib replacement is used if it not available in
20989 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20991 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.

21008 %llo or %llx format is passed. (Bug#8545)
21010 * window.c (window_scroll_line_based): Use a marker instead of
21011 simple variables to record original value of point. (Bug#7952)

21014 produced by %s or %c overflows available buffer space. (Bug#8545)
21016 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
21018 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
21019 (SIZE_MAX): Move defn after all includes, as they might #define it.
21021 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21023 * w32.c (init_environment): Warn about defaulting HOME to C:\.
21025 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21027 * keyboard.c (Qdelayed_warnings_hook): Define.
21028 (command_loop_1): Run `delayed-warnings-hook'
21029 if Vdelayed_warnings_list is non-nil.
21030 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
21031 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
21033 2011-04-28 Eli Zaretskii <eliz@gnu.org>
21035 * doprnt.c (doprnt): Don't return value smaller than the buffer
21036 size if the message was truncated. (Bug#8545).
21038 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
21040 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
21041 (Fx_window_property): #if-0 the whole functions, not just the bodies.
21043 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21045 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
21047 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
21049 * makefile.w32-in: Update dependencies.
21051 2011-04-27 Eli Zaretskii <eliz@gnu.org>
21053 Improve `doprnt' and its usage. (Bug#8545)
21054 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
21055 `format_end'. Remove support for %l as a conversion specifier.
21056 Don't use xrealloc. Improve diagnostics when the %l size modifier
21057 is used. Update the commentary.
21059 * eval.c (verror): Simplify calculation of size_t.
21061 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
21064 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
21066 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
21069 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
21071 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
21072 This makes this file independent of the recent pseudovector change.
21074 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
21076 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
21078 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
21079 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
21080 Remove unused local.
21081 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
21083 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
21084 GCC 4.6.0 optimizes based on type-based alias analysis.
21085 For example, if b is of type struct buffer * and v of type struct
21086 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
21087 != &v->size, and therefore "v->size = 1; b->size = 2; return
21088 v->size;" must therefore return 1. This assumption is incorrect
21089 for Emacs, since it type-puns struct Lisp_Vector * with many other
21090 types. To fix this problem, this patch adds a new type struct
21091 vectorlike_header that documents the constraints on layout of vectors
21092 and pseudovectors, and helps optimizing compilers not get fooled
21093 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
21094 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
21095 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
21097 (XSETPVECTYPE): Rewrite in terms of new macro.
21098 (XSETPVECTYPESIZE): New macro, specifying both type and size.
21099 This is a bit clearer, and further avoids the possibility of
21100 undesirable aliasing.
21101 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
21102 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
21103 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
21104 since Lisp_Subr is a special case (no "next" field).
21105 (ASIZE): Now uses header.size rather than size.
21106 All previous uses of XVECTOR (foo)->size replaced to use this macro,
21107 to avoid the hassle of writing XVECTOR (foo)->header.size.
21108 (struct vectorlike_header): New type.
21109 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
21110 object, to help avoid aliasing.
21111 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
21112 (SUBRP): Likewise, since Lisp_Subr is a special case.
21113 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
21114 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
21115 (struct Lisp_Hash_Table): Combine first two members into a single
21116 struct vectorlike_header member. All uses of "size" and "next" members
21117 changed to be "header.size" and "header.next".
21118 * buffer.h (struct buffer): Likewise.
21119 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
21120 * frame.h (struct frame): Likewise.
21121 * process.h (struct Lisp_Process): Likewise.
21122 * termhooks.h (struct terminal): Likewise.
21123 * window.c (struct save_window_data, struct saved_window): Likewise.
21124 * window.h (struct window): Likewise.
21125 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
21126 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
21127 * buffer.c (init_buffer_once): Likewise.
21128 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
21130 * process.c (Fformat_network_address): Use local var for size,
21133 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
21135 Make the Lisp reader and string-to-float more consistent (Bug#8525)
21136 * data.c (atof): Remove decl; no longer used or needed.
21137 (digit_to_number): Move to lread.c.
21138 (Fstring_to_number): Use new string_to_number function, to be
21139 consistent with how the Lisp reader treats infinities and NaNs.
21140 Do not assume that floating-point numbers represent EMACS_INT
21141 without losing information; this is not true on most 64-bit hosts.
21142 Avoid double-rounding errors, by insisting on integers when
21143 parsing non-base-10 numbers, as the documentation specifies.
21144 * lisp.h (string_to_number): New decl, replacing ...
21145 (isfloat_string): Remove.
21146 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
21147 (read1): Do not accept +. and -. as integers; this
21148 appears to have been a coding error. Similarly, do not accept
21149 strings like +-1e0 as floating point numbers. Do not report
21150 overflow for integer overflows unless the base is not 10 which
21151 means we have no simple and reliable way to continue.
21152 Break out the floating-point parsing into a new
21153 function string_to_number, so that Fstring_to_number parses
21154 floating point numbers consistently with the Lisp reader.
21155 (digit_to_number): Move here from data.c. Make it static inline.
21156 (E_CHAR, EXP_INT): Remove, replacing with ...
21157 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
21158 (string_to_number): New function, replacing isfloat_string.
21159 This function checks for valid syntax and produces the resulting
21160 Lisp float number too. Rework it so that string-to-number
21161 no longer mishandles examples like "1.0e+". Use strtoumax,
21162 so that overflow for non-base-10 numbers is reported only when
21163 there's no portable and simple way to convert to floating point.
21165 * textprop.c (set_text_properties_1): Rewrite for clarity,
21166 and to avoid GCC warning about integer overflow.
21168 * intervals.h (struct interval): Use EMACS_INT for members
21169 where EMACS_UINT might cause problems. See
21170 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
21171 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
21172 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
21174 (offset_intervals): Tell GCC not to worry about length overflow
21175 when negating a negative length.
21177 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
21178 (overrun_check_free): Likewise.
21180 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
21181 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
21184 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21185 (gnutls_make_error): Rename local to avoid shadowing.
21186 (gnutls_emacs_global_deinit): ifdef out; not used.
21187 (Fgnutls_boot): Use const for pointer to readonly storage.
21188 Comment out unused local. Fix pointer signedness problems.
21190 * lread.c (openp): Don't stuff size_t into an 'int'.
21191 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
21192 about possible signed overflow.
21194 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
21195 (GDK_KEY_g): Don't define if already defined.
21196 (xg_prepare_tooltip): Avoid pointer signedness problem.
21197 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
21199 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
21200 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
21202 * xfns.c (Fx_window_property): Simplify a bit,
21203 to make a bit faster and to avoid GCC 4.6.0 warning.
21204 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
21206 * fns.c (internal_equal): Don't assume size_t fits in int.
21208 * alloc.c (compact_small_strings): Tighten assertion a little.
21210 Replace pEd with more-general pI, and fix some printf arg casts.
21211 * lisp.h (pI): New macro, generalizing old pEd macro to other
21212 conversion specifiers. For example, use "...%"pI"d..." rather
21213 than "...%"pEd"...".
21214 (pEd): Remove. All uses replaced with similar uses of pI.
21215 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
21216 * alloc.c (check_pure_size): Don't overflow by converting size to int.
21217 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
21218 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
21219 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
21220 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
21221 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
21223 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
21224 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
21225 * print.c (safe_debug_print, print_object): Likewise.
21226 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
21228 Use pI instead of if-then-else-abort. Use %p to avoid casts,
21229 avoiding the 0 flag, which is not portable.
21230 * process.c (Fmake_network_process): Use pI to avoid cast.
21231 * region-cache.c (pp_cache): Likewise.
21232 * xdisp.c (decode_mode_spec): Likewise.
21233 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
21234 behavior on 64-bit hosts with printf arg.
21235 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
21236 (x_stop_queuing_selection_requests): Likewise.
21237 (x_get_window_property): Don't truncate byte count to an 'int'
21240 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
21241 here, since it parses constructs like leading '-' and spaces,
21242 which are not wanted; and it overflows with large numbers.
21243 Instead, simply match F[0-9]+, which is what is wanted anyway.
21245 * alloc.c: Remove unportable assumptions about struct layout.
21246 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
21247 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
21248 (allocate_vectorlike, make_pure_vector): Use the new macros,
21249 plus offsetof, to remove unportable assumptions about struct layout.
21250 These assumptions hold on all porting targets that I know of, but
21251 they are not guaranteed, they're easy to remove, and removing them
21252 makes further changes easier.
21254 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
21255 This doesn't fix a bug but makes the code clearer.
21256 (string_overrun_cookie): Now const. Use initializers that
21257 don't formally overflow signed char, to avoid warnings.
21258 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
21259 can cause Emacs to crash when string overrun checking is enabled.
21260 (allocate_buffer): Don't assume sizeof (struct buffer) is a

22155 * syntax.c (skip_chars): Likewise.
22157 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
22158 This also lets GCC 4.6.0 generate slightly better loop code.
22160 * callint.c (Fcall_interactively): <, not <=, for optimization.
22161 (Fcall_interactively): Count the number of arguments produced,
22162 not the number of arguments given. This is simpler and lets GCC
22163 4.6.0 generate slightly better code.
22165 * ftfont.c: Distingish more carefully between FcChar8 and char.
22166 The previous code passed unsigned char * to a functions like
22167 strlen and xstrcasecmp that expect char *, which does not
22168 conform to the C standard.
22169 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
22170 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
22171 char * when the C standard requires it.
22173 * keyboard.c (read_char): Remove unused var.
22175 * eval.c: Port to Windows vsnprintf (Bug#8435).
22176 Include <limits.h>.
22177 (SIZE_MAX): Define if the headers do not.
22178 (verror): Do not give up if vsnprintf returns a negative count.
22179 Instead, grow the buffer. This ports to Windows vsnprintf, which
22180 does not conform to C99. Problem reported by Eli Zaretskii.
22181 Also, simplify the allocation scheme, by avoiding the need for
22182 calling realloc, and removing the ALLOCATED variable.
22184 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
22186 Remove invocations of doprnt, as Emacs now uses vsnprintf.
22187 But keep the doprint source code for now, as we might revamp it
22188 and use it again (Bug#8435).
22189 * lisp.h (doprnt): Remove.
22190 * Makefile.in (base_obj): Remove doprnt.o.
22191 * deps.mk (doprnt.o): Remove.
22193 error: Print 32- and 64-bit integers portably (Bug#8435).
22194 Without this change, on typical 64-bit hosts error ("...%d...", N)
22195 was used to print both 32- and 64-bit integers N, which relied on
22196 undefined behavior.
22197 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
22198 * lisp.h (error, verror): Mark as printf-like functions.
22199 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
22200 Report overflow in size calculations when allocating printf buffer.
22201 Do not truncate output string at its first null byte.
22202 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
22203 Truncate the output at a character boundary, since vsnprintf does not
22205 * charset.c (check_iso_charset_parameter): Convert internal
22206 character to string before calling 'error', since %c now has the
22208 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
22209 overflow when computing char to be passed to 'error'. Do not
22210 pass Lisp_Object to 'error'; pass the integer instead.
22211 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
22212 formatted with plain %d.
22214 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
22216 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
22218 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
22220 * xterm.c (x_catch_errors): Remove duplicate declaration.
22222 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
22224 * xdisp.c, lisp.h (message_nolog): Remove; unused.
22226 2011-04-10 Jim Meyering <meyering@redhat.com>
22228 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
22229 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
22230 return ssize_t not "int", and use size_t as the buffer length.
22231 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
22232 * gnutls.h: Update declarations.
22233 * process.c (read_process_output): Use ssize_t, to match.
22234 (send_process): Likewise.
22236 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22238 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
22240 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
22242 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
22243 Use unsigned char, to match FcChar8 type definition.
22245 * xterm.c (handle_one_xevent):
22246 * xmenu.c (create_and_show_popup_menu):
22247 * xselect.c (x_decline_selection_request)
22248 (x_reply_selection_request): Avoid type-punned deref of X events.
22250 2011-04-09 Eli Zaretskii <eliz@gnu.org>
22252 Fix some uses of `int' instead of EMACS_INT.
22253 * search.c (string_match_1, fast_string_match)
22254 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
22255 (scan_buffer, find_next_newline_no_quit)
22256 (find_before_next_newline, search_command, Freplace_match)
22257 (Fmatch_data): Make some `int' variables be EMACS_INT.
22259 * xdisp.c (display_count_lines): 3rd argument and return value now
22260 EMACS_INT. All callers changed.
22261 (pint2hrstr): Last argument is now EMACS_INT.
22263 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
22264 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
22265 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
22266 (decode_coding_utf_16, decode_coding_emacs_mule)
22267 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
22268 (decode_coding_ccl, decode_coding_charset)
22269 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
22270 (decode_coding_iso_2022, decode_coding_emacs_mule)
22271 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
22272 <char_offset, last_offset>: Declare EMACS_INT.
22273 (encode_coding_utf_8, encode_coding_utf_16)
22274 (encode_coding_emacs_mule, encode_invocation_designation)
22275 (encode_designation_at_bol, encode_coding_iso_2022)
22276 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
22277 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
22279 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
22280 (encode_invocation_designation): Last argument P_NCHARS is now
22282 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
22283 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
22285 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
22288 * ccl.c (Fccl_execute_on_string): Declare some variables
22291 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
22293 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
22295 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
22297 * process.c (Fformat_network_address): Doc fix.
22299 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
22301 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
22303 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
22305 * keyboard.c (read_char): Call Lisp function help-form-show,
22306 instead of using internal_with_output_to_temp_buffer.
22307 (Qhelp_form_show): New var.
22308 (syms_of_keyboard): Use DEFSYM macro.
22310 * print.c (internal_with_output_to_temp_buffer): Function deleted.
22312 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
22314 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
22316 * process.c (Flist_processes): Remove to Lisp.
22317 (list_processes_1): Delete.

22321 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
22323 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
22325 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
22327 Fix more problems found by GCC 4.6.0's static checks.
22329 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
22331 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
22333 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
22335 * xdisp.c (vmessage): Mark as a printf-like function.
22337 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
22339 * sound.c (sound_warning): Don't crash if arg contains a printf format.
22341 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
22342 printf-like functions.
22343 (tiff_load): Add casts to remove these marks before passing them
22344 to system-supplied API.
22346 * eval.c (Fsignal): Remove excess argument to 'fatal'.
22348 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
22349 This avoids several warnings with gcc -Wstrict-overflow.
22350 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
22351 directly, rather than having caller test rule sign. This avoids
22352 some unnecessary tests.
22353 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
22354 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
22355 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
22357 * xfont.c (xfont_text_extents): Remove var that was set but not used.
22358 (xfont_open): Avoid unnecessary tests.
22360 * composite.c (composition_gstring_put_cache): Use unsigned integer.
22362 * composite.h, composite.c (composition_gstring_put_cache):
22363 Use EMACS_INT, not int, for length.
22365 * composite.h (COMPOSITION_DECODE_REFS): New macro,
22366 breaking out part of COMPOSITION_DECODE_RULE.
22367 (COMPOSITION_DECODE_RULE): Use it.
22368 * composite.c (get_composition_id): Remove unused local vars,
22369 by using the new macro.
22371 * textprop.c (set_text_properties_1): Change while to do-while,
22372 since the condition is always true at first.
22374 * intervals.c (graft_intervals_into_buffer): Mark var as used.
22375 (interval_deletion_adjustment): Return unsigned value.
22378 * process.c (list_processes_1, create_pty, read_process_output):
22379 (exec_sentinel): Remove vars that were set but not used.
22380 (create_pty): Remove unnecessary "volatile"s.

22383 (read_process_output): Simplify nbytes computation if buffered.
22385 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
22387 * syntax.c (scan_words): Remove var that was set but not used.
22388 (update_syntax_table): Use unsigned instead of int.
22390 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
22391 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
22392 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
22394 * print.c (print_error_message): Avoid int overflow.
22396 * font.c (font_list_entities): Redo for clarity,
22397 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22399 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22400 (font_score): Avoid potential overflow in diff calculation.
22402 * fns.c (substring_both): Remove var that is set but not used.
22403 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22405 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22407 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22408 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22409 can always succeed if overflow has undefined behavior.
22411 * search.c (boyer_moore, wordify): Remove vars set but not used.
22412 (wordify): Omit three unnecessary tests.
22414 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22415 All callers changed. This avoids the need for an unused var.
22417 * casefiddle.c (casify_region): Remove var that is set but not used.
22419 * dired.c (file_name_completion): Remove var that is set but not used.
22421 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22423 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22424 (Finsert_file_contents): Remove unnecessary code checking fd.
22426 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22427 Check for integer overflow on size calculations.
22429 * buffer.c (Fprevious_overlay_change): Remove var that is set
22432 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22433 Remove vars that are set but not used.
22434 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22435 (timer_check_2): Mark vars as initialized.
22437 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22439 * image.c (lookup_image): Remove var that is set but not used.
22440 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22442 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22443 that are set but not used.
22445 * xfns.c (make_invisible_cursor): Don't return garbage
22446 if XCreateBitmapFromData fails (Bug#8410).
22448 * xselect.c (x_get_local_selection, x_handle_property_notify):
22449 Remove vars that are set but not used.
22451 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
22452 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
22454 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
22455 Remove var that is set but not used.
22456 (scroll_bar_windows_size): Now size_t, not int.
22457 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
22458 Check for overflow.
22460 * xfaces.c (realize_named_face): Remove vars that are set but not used.
22461 (map_tty_color) [!defined MSDOS]: Likewise.
22463 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22465 * coding.c: Remove vars that are set but not used.
22466 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22467 All callers changed.
22468 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22469 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22470 (decode_coding_charset): Remove vars that are set but not used.
22472 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22473 that is set but not used.
22475 * print.c (print_object): Remove var that is set but not used.
22477 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22478 The gnulib version avoids calling malloc in the usual case,
22479 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22480 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22481 * filelock.c (current_lock_owner): Likewise.
22482 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22483 * sysdep.c: Include allocator.h, careadlinkat.h.
22484 (emacs_no_realloc_allocator): New static constant.
22485 (emacs_readlink): New function.
22486 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22487 ../lib/careadlinkat.h.
22489 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22491 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22492 first non-nil return value).
22494 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
22496 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22497 if not defined (Bug#8403).
22499 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22501 * xdisp.c (display_count_lines): Remove parameter `start',
22502 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22503 (get_char_face_and_encoding): Remove parameter `multibyte_p',
22504 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22505 (fill_stretch_glyph_string): Remove parameters `row' and `area',
22506 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22507 and thereabouts. All callers changed.
22508 (get_per_char_metric): Remove parameter `f', unused since
22509 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
22511 2011-04-02 Jim Meyering <meyering@redhat.com>
22513 do not dereference NULL upon failed strdup
22514 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22515 (ns_get_family): Likewise.
22517 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
22519 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
22521 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
22523 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
22526 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
22528 Add lexical binding.
22530 * window.c (Ftemp_output_buffer_show): New fun.
22531 (Fsave_window_excursion):
22532 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
22534 * lread.c (lisp_file_lexically_bound_p): New function.
22535 (Fload): Bind Qlexical_binding.
22536 (readevalloop): Remove `evalfun' arg.
22537 Bind Qinternal_interpreter_environment.
22538 (Feval_buffer): Bind Qlexical_binding.
22539 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
22541 (syms_of_lread): Declare `lexical-binding'.
22543 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
22545 * keyboard.c (eval_dyn): New fun.
22546 (menu_item_eval_property): Use it.
22548 * image.c (parse_image_spec): Use Ffunctionp.
22550 * fns.c (concat, mapcar1): Accept byte-code-functions.
22552 * eval.c (Fsetq): Handle lexical vars.
22553 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22554 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22555 (FletX, Flet): Obey lexical binding.
22556 (Fcommandp): Handle closures.
22557 (Feval): New `lexical' arg.
22558 (eval_sub): New function extracted from Feval. Use it almost
22559 everywhere where Feval was used. Look up vars in lexical env.
22561 (Ffunctionp): Move from subr.el.
22562 (Ffuncall): Handle closures.
22563 (apply_lambda): Remove `eval_flags'.
22564 (funcall_lambda): Handle closures and new byte-code-functions.
22565 (Fspecial_variable_p): New function.
22566 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22567 but without exporting it to Lisp.
22569 * doc.c (Fdocumentation, store_function_docstring):
22570 * data.c (Finteractive_form): Handle closures.
22572 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22575 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22577 (exec_byte_code): New function extracted from Fbyte_code to handle new
22578 calling convention for byte-code-functions. Add new byte-codes.
22580 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22582 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22584 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22586 * xdisp.c (redisplay_internal): Fix prototype.
22588 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22590 * xdisp.c (SCROLL_LIMIT): New macro.
22591 (try_scrolling): Use it when setting scroll_limit.
22592 Limit scrolling to 100 screen lines.
22593 (redisplay_window): Even when falling back on "recentering",
22594 position point in the window according to scroll-conservatively,
22595 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22597 (try_scrolling): When point is above the window, allow searching
22598 as far as scroll_max, or one screenful, to compute vertical
22599 distance from PT to the scroll margin position. This prevents
22600 try_scrolling from unnecessarily failing when
22601 scroll-conservatively is set to a value slightly larger than the
22602 window height. Clean up the case of PT below the margin at bottom
22603 of window: scroll_max can no longer be INT_MAX. When aggressive
22604 scrolling is in use, don't let point enter the opposite scroll
22605 margin as result of the scroll.
22606 (syms_of_xdisp) <scroll-conservatively>: Document the
22607 threshold of 100 lines for never-recentering scrolling.
22609 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22611 * dispextern.h (move_it_by_lines):
22612 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22613 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22614 (message_log_check_duplicate): Remove parameters `prev_bol' and
22615 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22616 (redisplay_internal): Remove parameter `preserve_echo_area',
22617 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22619 * indent.c (Fvertical_motion):
22620 * window.c (window_scroll_pixel_based, Frecenter):
22621 Don't pass `need_y_p' to `move_it_by_lines'.
22623 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22625 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22626 steal a few bits to be more compact.
22627 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22628 Remove unneeded casts.
22630 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22632 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22634 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22635 binding" message (bug#7967).
22637 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22639 Fix more problems found by GCC 4.6.0's static checks.
22641 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22642 Remove unused local var.
22644 * editfns.c (Fmessage_box): Remove unused local var.
22646 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22647 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22648 Omit unused local vars.
22649 * window.c (shrink_windows): Omit unused local var.
22650 * menu.c (digest_single_submenu): Omit unused local var.
22651 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22652 Omit unused local var.
22654 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22655 Don't assume string length fits in int.
22656 (keyremap_step, read_key_sequence): Use size_t for sizes.
22657 (read_key_sequence): Don't check last_real_key_start redundantly.
22659 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22660 instead of alloca (Bug#8344).
22662 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22663 (Fbacktrace_frame): Don't assume nframes fits in int.
22665 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22667 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22670 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22672 * cm.c (calccost): Turn while-do into do-while, for clarity.
22674 * keyboard.c (syms_of_keyboard): Use the same style as later
22675 in this function when indexing through an array. This also
22676 works around GCC bug 48267.
22678 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22680 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

22683 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22685 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22686 This avoids undefined behavior on integer overflow, and is a bit
22687 more convenient anyway since it is compared to a size_t variable.
22689 Variadic C functions now count arguments with size_t, not int.
22690 This avoids an unnecessary limitation on 64-bit machines, which
22691 caused (substring ...) to crash on large vectors (Bug#8344).
22692 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22693 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

22699 (internal_condition_case_n, run_hook_with_args, apply_lambda)
22700 (funcall_lambda, mark_backtrace): Likewise.
22701 * fns.c (concat): Likewise.
22702 * frame.c (x_set_frame_parameters): Likewise.
22703 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22704 0 if not found, not -1. All callers changed.
22706 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22707 (stack_copy_size): Now size_t, not int.
22708 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

22713 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22714 All callers changed.
22716 * lisp.h (multibyte_char_to_unibyte):
22717 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22718 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

22720 * cmds.c (internal_self_insert):
22721 * editfns.c (general_insert_function):
22722 * keymap.c (push_key_description):
22723 * search.c (Freplace_match):
22724 * xdisp.c (message_dolog, set_message_1): All callers changed.
22726 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
22728 * keyboard.c (safe_run_hook_funcall): New function.
22729 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22730 don't set the hook to nil, but remove the offending function instead.
22731 (Qcommand_hook_internal): Remove, unused.
22732 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22733 Vcommand_hook_internal.
22735 * eval.c (enum run_hooks_condition): Remove.
22736 (funcall_nil, funcall_not): New functions.
22737 (run_hook_with_args): Call each function through a `funcall' argument.
22738 Remove `cond' argument, now redundant.
22739 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
22740 (Frun_hook_with_args_until_failure): Adjust accordingly.
22741 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
22743 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22745 * dispextern.h (string_buffer_position): Remove declaration.
22747 * print.c (strout): Remove parameter `multibyte', unused since
22748 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
22750 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
22751 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22752 All callers changed.
22754 * w32.c (_wsa_errlist): Use braces for struct initializers.
22756 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
22757 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
22758 All callers changed.
22759 (string_buffer_position): Likewise. Also, make static (it's never
22760 used outside xdisp.c).
22761 (cursor_row_p): Remove parameter `w', unused since
22762 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

22764 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
22765 All callers changed.
22767 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22769 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

22780 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
22782 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>

22795 2011-03-26 Eli Zaretskii <eliz@gnu.org>
22797 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
22798 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
22800 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
22802 * w32.c (read_unc_volume): Use parameter `henum', instead of
22803 global variable `wget_enum_handle'.
22805 * keymap.c (describe_vector): Remove parameters `indices' and
22806 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

22818 * xmenu.c (show_help_event, menu_help_callback):
22819 Adjust calls to `show_help_echo'.
22821 * gtkutil.c (xg_maybe_add_timer):
22822 * keyboard.c (readable_events):
22823 * process.c (wait_reading_process_output):
22824 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
22826 * insdel.c (adjust_markers_gap_motion):
22827 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

22901 2011-03-23 Julien Danjou <julien@danjou.info>
22903 * term.c (Fsuspend_tty, Fresume_tty):
22904 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22905 * window.c (temp_output_buffer_show):

22910 * editfns.c (save_excursion_restore):
22911 * cmds.c (internal_self_insert):
22912 * callint.c (Fcall_interactively):
22913 * buffer.c (Fkill_all_local_variables):
22914 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22916 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22917 unconditionally since it does the check itself.
22919 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22921 Fix more problems found by GCC 4.5.2's static checks.
22923 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22924 the first time through the loop, since we know p0 < p1 then.
22925 This also avoids a gcc -Wstrict-overflow warning.
22927 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22928 leading to a memory leak, possible in functions like
22929 load_charset_map_from_file that can allocate an unbounded number
22930 of objects (Bug#8318).
22932 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22933 that could (at least in theory) be that large.
22935 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22936 This is less likely to overflow, and avoids undefined behavior if
22937 overflow does occur. All callers changed. Use strtoul to scan
22938 for the unsigned long integer.
22939 (pint2hrstr): Simplify and tune code slightly.
22940 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

22948 This also avoids a warning with gcc -Wstrict-overflow.
22950 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22953 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22955 * process.c (Fmake_network_process): Use socklen_t, not int,
22956 where POSIX says socklen_t is required in portable programs.
22957 This fixes a porting bug on hosts like 64-bit HP-UX, where
22958 socklen_t is wider than int (Bug#8277).
22959 (Fmake_network_process, server_accept_connection):
22960 (wait_reading_process_output, read_process_output):
22963 * process.c: Rename or move locals to avoid shadowing.
22964 (list_processes_1, Fmake_network_process):
22965 (read_process_output_error_handler, exec_sentinel_error_handler):
22966 Rename or move locals.
22967 (Fmake_network_process): Define label "retry_connect" only if needed.
22968 (Fnetwork_interface_info): Fix pointer signedness.

22970 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22971 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22973 Make tparam.h and terminfo.c consistent.
22974 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22975 Include tparam.h instead, since it declares them.
22976 * cm.h (PC): Remove extern decl; tparam.h now does this.
22977 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22978 * terminfo.c: Include tparam.h, to check interfaces.
22979 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22980 (tparam): Adjust signature to match interface in tparam.h;
22981 this removes some undefined behavior. Check that outstring and len
22982 are zero, which they always are with Emacs.
22983 * tparam.h (PC, BC, UP): New extern decls.
22985 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
22986 (xftfont_open): Rename locals to avoid shadowing.
22988 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
22989 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
22990 (OTF_TAG_SYM): Omit macro if not needed.
22991 (ftfont_list): Remove unused local.
22992 (get_adstyle_property, ftfont_pattern_entity):
22993 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
22994 Rename locals to avoid shadowing.
22996 * xfont.c (xfont_list_family): Mark var as initialized.
22998 * xml.c (make_dom): Now static.
23000 * composite.c (composition_compute_stop_pos): Rename local to
23002 (composition_reseat_it): Remove unused locals.
23003 (find_automatic_composition, composition_adjust_point): Likewise.
23004 (composition_update_it): Mark var as initialized.
23005 (find_automatic_composition): Mark vars as initialized,
23006 with a FIXME (Bug#8290).
23008 character.h: Rename locals to avoid shadowing.
23009 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
23010 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
23011 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
23012 (BUF_DEC_POS): Be more systematic about renaming local temporaries
23013 to avoid shadowing.
23015 * textprop.c (property_change_between_p): Remove; unused.
23017 * intervals.c (interval_start_pos): Now static.
23019 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
23021 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
23022 Rename locals to avoid shadowing.
23024 * sound.c (wav_play, au_play, Fplay_sound_internal):
23025 Fix pointer signedness.
23026 (alsa_choose_format): Remove unused local var.
23027 (wav_play): Initialize a variable to 0, to prevent undefined
23028 behavior (Bug#8278).
23030 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
23032 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
23034 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
23035 clobbering (Bug#8298).
23036 * sysdep.c (sys_subshell): Likewise.
23037 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
23039 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
23040 This should get cleaned up, so that child_setup has the
23041 same signature on all platforms.
23043 * callproc.c (call_process_cleanup): Now static.
23044 (relocate_fd): Rename locals to avoid shadowing.
23046 2011-03-22 Chong Yidong <cyd@stupidchicken.com>

23213 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23214 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
23215 to use the following functions instead of these macros.
23216 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
23217 EMACS_INT, since callers assume the returned value fits in int.
23218 (upcase1): Likewise, for UPCASE_TABLE.
23219 (uppercasep, lowercasep, upcase): New static inline functions.
23220 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

23230 (regex_compile, re_match_2_internal): Mark locals as initialized.
23231 (RETALLOC_IF): Define only if needed.
23232 (WORDCHAR_P): Likewise. This one is never needed, but is used
23233 only in a comment talking about a compiler bug, so put inside
23234 the #if 0 of that comment.
23235 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
23236 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

23262 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
23263 New macros, so that the caller can use some names other than
23264 gcpro1, gcpro2, etc.
23265 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
23267 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
23268 argument, for consistency with GCPRO2_VAR, etc: it is now the
23269 prefix of the variable, not the variable itself. All uses
23271 * dired.c (directory_files_internal, file_name_completion):
23272 Rename locals to avoid shadowing.
23274 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
23275 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
23276 dired.c's scmp function, had undefined behavior.
23277 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
23278 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
23279 * buffer.h: ... to here, because these macros use current_buffer,
23280 and the new implementation with inline functions needs to have
23281 current_buffer in scope now, rather than later when the macros
23283 (downcase, upcase1): New static inline functions.
23284 (DOWNCASE, UPCASE1): Reimplement using these functions.
23285 This avoids undefined behavior in expressions like
23286 DOWNCASE (x) == DOWNCASE (y), which previously suffered
23287 from race conditions in accessing the global variables
23288 case_temp1 and case_temp2.
23289 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
23290 * lisp.h (case_temp1, case_temp2): Remove their decls.
23291 * character.h (ASCII_CHAR_P): Move from here ...
23292 * lisp.h: ... to here, so that the inline functions mentioned
23293 above can use them.
23295 * dired.c (directory_files_internal_unwind): Now static.
23297 * fileio.c (file_name_as_directory, directory_file_name):

23300 (file_name_as_directory): Use const pointers when appropriate.
23301 (Fexpand_file_name): Likewise. In particular, newdir might
23302 point at constant storage, so make it a const pointer.
23303 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
23304 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
23306 (Fset_file_times, Finsert_file_contents, auto_save_error):

23311 to avoid shadowing.
23313 * marker.c (bytepos_to_charpos): Remove; unused.
23315 * lisp.h (verify_bytepos, count_markers): New decls,
23316 so that gcc does not warn that these functions aren't declared.
23318 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
23319 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
23320 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
23321 (copy_text): Remove unused local var.
23323 * filelock.c (within_one_second): Now static.
23324 (lock_file_1): Rename local to avoid shadowing.
23326 * buffer.c (fix_overlays_before): Mark locals as initialized.
23327 (fix_start_end_in_overlays): Likewise. This function should be
23328 simplified by using pointers-to-pointers, but that's a different
23330 (switch_to_buffer_1): Now static.
23331 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
23332 (report_overlay_modification): Rename locals to avoid shadowing.
23334 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
23335 Fix pointer signedness issue.
23336 (sys_subshell): Mark local as volatile if checking for lint,
23337 to suppress a gcc -Wclobbered warning that does not seem to be right.
23338 (MAXPATHLEN): Define only if needed.
23340 * process.c (serial_open, serial_configure): Move decls from here ...
23341 * systty.h: ... to here, so that they can be checked.
23343 * fns.c (get_random, seed_random): Move extern decls from here ...
23344 * lisp.h: ... to here, so that they can be checked.
23346 * sysdep.c (reset_io): Now static.
23347 (wait_for_termination_signal): Remove; unused.
23349 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

23352 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
23353 (DENSE_TABLE_SIZE): Remove; unused.
23354 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
23355 (describe_map_tree):
23356 Rename locals to avoid shadowing.
23358 * keyboard.c: Declare functions static if they are not used elsewhere.
